    We explored physiological changes correlated with song tutoring by recording the responses of caudal nidopallium neurons of zebra finches aged P21-P24 (days post hatching) to a broad spectrum of natural and synthetic stimuli. Those birds raised with their fathers tended to show behavioral evidence of song memorization but not of singing; thus auditory responses were not confounded by the birds' own vocalizations. In study 1, 37 of 158 neurons (23%) in 17 of 22 tutored and untutored birds were selective for only 1 of 10 stimuli comprising broadband signals, early juvenile songs and calls, female calls, and adult songs. Approximately 30% of the selective neurons (12/37 neurons in 9 birds) were selective for adult conspecific songs. All these were found in the song system nuclei HVC and paraHVC. Of 122 neurons (17 birds) in tutored birds, all of the conspecific song-selective neurons (8 neurons in 6 birds) were selective for the adult tutor song; none was selective for unfamiliar song. In study 2 with a different sampling strategy, we found that 11 of 12 song-selective neurons in 6 of 7 birds preferred the tutor song; none preferred unfamiliar or familiar conspecific songs. Most of these neurons were found in caudal lateral nidopallium (NCL) below HVC. Thus by the time a bird begins to sing, there are small numbers of tutor song-selective neurons distributed in several forebrain regions. We hypothesize that a small population of higher-order auditory neurons is innately selective for complex features of behaviorally relevant stimuli and these responses are modified by specific perceptual/social experience during development.

    Full Text Available This paper considers professional development in a context that is familiar and problematic to teaching teams in tertiary education everywhere, that of delivering online programmes with an ever-decreasing complement of staff. The Teaching Qualification Further Education (TQFE teaching team at University of Dundee confronted the reality of reduced staff numbers by centralising tutoring and support for programme participants. The new system involves standardising tutoring as far as possible through generic email, blog and microblog accounts, all badged “TQFE-Tutor” and staffed on a roster basis. Once the new “rules of engagement” via TQFE-Tutor were in place, it became clear that in addition to benefits in terms of student support, there were other unintended positive consequences: opportunities for informal professional development for staff and the promotion of effective team working. The experience of collective tutoring has facilitated collaboration on a range of innovations within online learning. This paper describes the evolution of the TQFE-Tutor innovation and reports upon a small scale study which was carried out to gather the views of the tutor team working with TQFE-Tutor. The authors conclude that the centralisation of communication and tutoring on the TQFE programme has been highly beneficial in terms of professional development for the team.

  5. Social interaction with a tutor modulates responsiveness of specific auditory neurons in juvenile zebra finches.

    Behavioral states of animals, such as observing the behavior of a conspecific, modify signal perception and/or sensations that influence state-dependent higher cognitive behavior, such as learning. Recent studies have shown that neuronal responsiveness to sensory signals is modified when animals are engaged in social interactions with others or in locomotor activities. However, how these changes produce state-dependent differences in higher cognitive function is still largely unknown. Zebra finches, which have served as the premier songbird model, learn to sing from early auditory experiences with tutors. They also learn from playback of recorded songs however, learning can be greatly improved when song models are provided through social communication with tutors (Eales, 1989; Chen et al., 2016). Recently we found a subset of neurons in the higher-level auditory cortex of juvenile zebra finches that exhibit highly selective auditory responses to the tutor song after song learning, suggesting an auditory memory trace of the tutor song (Yanagihara and Yazaki-Sugiyama, 2016). Here we show that auditory responses of these selective neurons became greater when juveniles were paired with their tutors, while responses of non-selective neurons did not change. These results suggest that social interaction modulates cortical activity and might function in state-dependent song learning. Copyright © 2018 Elsevier B.V. All rights reserved.

    Peer tutoring can benefit both tutors and tutored students, but information is lacking regarding establishing and measuring outcomes of such a program at new medical schools. To examine the outcomes of a pilot peer tutoring initiative and explore the implications for long-term program development. Fifty-one osteopathic medical students who participated in a pilot peer tutoring program during the 2013-2014 academic year were surveyed regarding satisfaction with the program. Course grade means for the tutors (all courses) and tutored students (specific courses) were analyzed before and after participating in the tutoring experience. Data analyses were performed using frequency distributions, t tests, and qualitative assessment of emergent themes. The survey had a 76% response rate (39 of 51 students). Both tutored students and tutors were satisfied with the tutoring program. Statistically significant changes in course grades for the tutored courses were noted at 3 to 4 and 8 to 9 months among the tutored students who were most at risk for failure (P=.001). Tutor course grades showed no significant changes for any of the courses in which they were enrolled (P=.445). Learning gains were realized by the students at greatest academic risk. Additional research is needed to evaluate long-term outcomes.

    Discussion: Analyzing the tutors’ scores of their motivation for PBL tutoring yielded three significantly correlated constructs representing tutoring self-efficacy, tutoring interest and tutoring value. The findings demonstrated high internal consistency reliability of the questionnaire, strong correlation between the three constructs as well as correlations between the constructs and the self-rated tutoring skills scores. Taken together, the current study demonstrates that the newly developed instrument measuring motivation for PBL tutoring exhibits good psychometric properties. The findings in this paper pave the way for further studies for refining the measurement of this construct in different problem-based contexts.

    Many interdisciplinary Ph.D. programs admit students of different educational backgrounds who receive a first year of a general curriculum education. However, student preparation for this curriculum varies, and methods are needed to provide academic support. Graduate student peer tutoring was piloted as an initiative funded by a National Institutes of Health (NIH) Initiative for Minority Student Development award to the University of Medicine and Dentistry of New Jersey-Robert Wood Johnson Medical School (UMDNJ-RWJMS) and is now offered to all students in the interdisciplinary Molecular Biosciences Ph.D. program between Rutgers, The State University of New Jersey, and UMDNJ-RWJMS. Tutoring occurs individually or in small groups and has grown over the past 5 years in the number of students tutored and hours of tutoring. The program was evaluated by surveying and interviewing both tutors and students concerning process variables (e.g. awareness, frequency) and impact variables (e.g. perceived benefits, motivators), as well as by assessing changes in exam scores for the four core courses of the first-year graduate curriculum.

    Over the last decade robotics has attracted a great deal of interest from teachers and researchers as a valuable educational tool from preschool to highschool levels. The implementation of social-support behaviors in robot tutors, in particular in the emotional dimension, can make a significant contribution to learning efficiency. With the aim of contributing to the rising field of affective robot tutors we have developed ARTIE (Affective Robot Tutor Integrated Environment). We offer an architectural pattern which integrates any given educational software for primary school children with a component whose function is to identify the emotional state of the students who are interacting with the software, and with the driver of a robot tutor which provides personalized emotional pedagogical support to the students. In order to support the development of affective robot tutors according to the proposed architecture, we also provide a methodology which incorporates a technique for eliciting pedagogical knowledge from teachers, and a generic development platform. This platform contains a component for identiying emotional states by analysing keyboard and mouse interaction data, and a generic affective pedagogical support component which specifies the affective educational interventions (including facial expressions, body language, tone of voice,…) in terms of BML (a Behavior Model Language for virtual agent specification) files which are translated into actions of a robot tutor. The platform and the methodology are both adapted to primary school students. Finally, we illustrate the use of this platform to build a prototype implementation of the architecture, in which the educational software is instantiated with Scratch and the robot tutor with NAO. We also report on a user experiment we carried out to orient the development of the platform and of the prototype. We conclude from our work that, in the case of primary school students, it is possible to identify, without

    Good teaching requires spontaneous, immediate, and appropriate action in response to various situations. It is even more crucial in problem-based learning (PBL) tutorials, as the tutors, while directing students toward the identification and attainment of learning objectives, must stimulate them to contribute to the process and provide them with constructive feedback. PBL tutors in medicine lack opportunities to receive feedback from their peers on their teaching strategies. Moreover, as tutorials provide little or no time to stop and think, more could be learned by reflecting on the experience than from the experience itself. We designed and evaluated a faculty development approach to developing PBL tutors that combined self-reflection and peer feedback processes, both powerful techniques for improving performance in education. We developed an observation instrument for PBL facilitation to be used both by tutors to self-observe and reflect on own teaching strategies and by peers to observe and provide feedback to tutors. Twenty PBL sessions were video-recorded. Tutors completed the instrument immediately after their PBL session and again while watching their video-recorded session (self-observation). A group of three observers completed the instrument while watching each recorded session and provided feedback to each tutor (peer observation and feedback). We investigated tutors' perceptions of the feasibility and acceptability of the approach and gathered data on its effectiveness in enhancing tutors' facilitation skills. The preclinical medical curriculum at the University of Geneva is essentially taught by PBL. A new program of faculty development based on self-observation and peer feedback was offered to voluntary tutors and evaluated. Our results suggest that self-observation and peer feedback, supported by an instrument, can be effective in enhancing tutors' facilitation skills. Reflection on self-observation raised teachers' awareness of the effectiveness of

    Full Text Available Subsongs are vocal trials uttered by young birds to practice songs. Among songbirds, subsongs are displayed by individuals in their first year of life. Studies on Zebra Finches Poephila guttata suggest that the juveniles learn their songs from a vocal tutor, their father. In this study we examine the subsongs in six captive-born Meyer's Parrots Poicephalus meyeri, from fledging time to weaning. Recordings of songs from chicks and fathers were analyzed for similarities in frequency and time parameters. With age, the subsongs of the chicks became more similar to the vocalizations of the fathers with 20% similarity rating in the first week after fledging to 100% at weaning time. Moreover, fledged chicks were exposed to a wide range of stimuli from several species of parrots breeding pairs caged nearby but chicks exclusively learned their fathers' songs. Our data support the hypothesis that Meyer's Parrots are vocal learners and use their father as their tutor.Os ''subsongs'' são ensaios vocais emitidos pelas aves jovens para exercitar suas vozes. Nos pássaros canoros, ''subsongs'' são exibidos por indivíduos em seu primeiro ano de vida. Estudos com Poephila guttata sugerem que os jovens aprendem seus cantos de um tutor vocal, seu pai. Neste trabalho examinamos os ''subsongs'' em seis papagaios Poicephalus meyeri nascidos em cativeiro, desde a saída do ninho até a emancipação. Gravações dos cantos dos filhotes e dos pais foram analisadas para medir as similaridades nos parâmetros de freqüência e tempo. Com a idade, os ''subsongs'' dos filhotes viraram mais semelhantes às vocalizações dos pais, com 20% de similaridade na primeira semana após a saída do ninho até 100% na hora da emancipação. Ademais, os filhotes foram expostos a uma grande variedade de estímulos de várias outras espécies de papagaios nidificando em gaiolas vizinhas, mas eles aprenderam somente os cantos de seus pais.

    NASA also seeks to advance American education by employing the technology utilization process to develop a computerized, artificial intelligence-based Intelligent Tutoring System (ITS) to help high school and college physics students. The tutoring system is designed for use with the lecture and laboratory portions of a typical physics instructional program. Its importance lies in its ability to observe continually as a student develops problem solutions and to intervene when appropriate with assistance specifically directed at the student's difficulty and tailored to his skill level and learning style. ITS originated as a project of the Johnson Space Center (JSC). It is being developed by JSC's Software Technology Branch in cooperation with Dr. R. Bowen Loftin at the University of Houston-Downtown. Program is jointly sponsored by NASA and ACOT (Apple Classrooms of Tomorrow). Other organizations providing support include Texas Higher Education Coordinating Board, the National Research Council, Pennzoil Products Company and the George R. Brown Foundation. The Physics I class of Clear Creek High School, League City, Texas are providing the classroom environment for test and evaluation of the system. The ITS is a spinoff product developed earlier to integrate artificial intelligence into training/tutoring systems for NASA astronauts flight controllers and engineers.

    student tutors have a long tradition in gross anatomy instruction. However, the full potential of the tutors is generally not tapped, since little attention is paid to their technical and didactical training. The aim of this paper is to report a systematic approach to the development, didactic reasoning and implementation of a curriculum for training student tutors in gross anatomy. the training program was developed using the six-step approach of Kern's curriculum development model. For needs assessment, the literature research was amended by a survey among the 1st and 2nd year students of the dissection course (n=167) and two independent 90 min focus group interviews with the tutors who supervised these students (n=15). Protocols were transcribed and analyzed by margin coding. The training curriculum was setup on the basis of these data. corresponding to the literature, the students want student tutors with good teaching competence as well as adequate content knowledge and technical competence. Supporting that, the tutors request a training program enhancing their didactic skills as well as their knowledge of content and working using relevant methods. Thus, a combined didactic and professional training program has been developed. Six professional and 11 didactic learning objectives were defined. A 3 weeks training curriculum was implemented, using microteaching and group exercises for didactics and active dissection for technical training. Both parts were interlocked on a contextual and practical level. our focus group analyses revealed that a specific training program for student tutors in the dissection course is necessary. We describe a feasible task-oriented training curriculum combining didactic and professional objectives. 2010. Published by Elsevier GmbH.

The  aim of this  study  was to show the  profile of a tutor of biochemistry and  its influence in his academic,  didactic  and  social development.  A questionnaire of 31 questions  was answered  by tutors that acted  between  2000 and  2004, and  the  main  comments  were detached.   From  29 tutors  who frequented  the program  during the period (5 tutors II and 24 tutors I, 19 answered the questionnaire. The  average  time  of permanence  of the tutors in  this  program  was  9 months,  varying  from  4 to28 months.   Fourteen from the  19 students that worked  as tutors chose to  act  in the  program  for the  possibility  of teaching  and  also helped  them  to  be more  extroverted and  they  felt satisfied  to help other  people which contributes effectively for the  training of the  ones who want to  follow the academic career.  It also contributes professionally by increasing the capacity of relationship in group, dynamism,  decisions and  organization, characteristics that are more and more appraised  in the  job market.    It  was verified that the  studies  of the  tutors were modified  by  the  necessity  of preparing the  classes because  to teach,  you need to understand the subject  and  you need to present  it to the student in the best way, you have to consider the life and the previous knowledge of the student.

    Full Text Available The development of Diapterus peruvianus (Sauvage 1879 is based on 60 larvae collected in superficial tows made in Bahía Concepción, and on 16 prejuvenile and juvenile organisms collected in Bahía de La Paz, B. C. S., México, using a standard plankton net and a rectangular epibenthonic net, respectively. Larvae of D. peruvianus show three large blotches on the dorsum of the gut that can fuse together and give the appearance of one large continuous blotch. There are two to three pre-anal pigments and 16 post-anal pigments in the ventral midline; cephalic pigments are present from the postflexion stage, as well as a serrated preoperculum. The prejuvenile and juvenile organisms are distinguished by their body depth, the analfin formula, the serrated preoperculum and the base pigments in the dorsal and anal fins.El desarrollo de Diapterus peruvianus se analizó con base en 60 larvas recolectadas en Bahía Concepción y 16 pre-juveniles y juveniles recolectados en la Ensenada de La Paz, B. C. S. México, usando respectivamente, una red estándar de plancton en arrastres superficiales y una red epibentónica para arrastres de plancton. Las larvas presentan desde la pre-flexión tres manchas alargadas sobre la superficie dorsal de la masa visceral, que pueden unirse y dar apariencia de pigmentación continua, observándose hasta 16 pigmentos post-anales en la línea media ventral y de dos a tres pigmentos pre-anales; la pigmentación cefálica así como la forma aserrada del pre-opérculo característica del género, aparecen a partir de la post-flexión. Los organismos pre-juveniles y juveniles se distinguen por la profundidad del cuerpo, la fórmula de la aleta anal, la fina forma aserrada del pre-opérculo y la pigmentación en la base de las aletas dorsal y anal.

    Full Text Available The author deals with tutorship as one of the most effective forms of one-to-one learning. The relationship between a tutor and a student is studied in detail and it is established that the quality of such a relationship can be considerably better than the one, where a tutor and a student arc engaged in a more formal one. The article, which is based on the data gathered from a research, speaks about conditions, which are necessary for an informal tutor-student re lationship to evolve. The author also answers the question of the characteristics the students expect from their tutors. What should, therefore, a personal profile of an informal tutor be? This also partly answers the question of a good leader and the characteristics a good leader possesses, since leaders are also good tutors. Informal tutors, who offered skills, knowledge and useful insight, were mostly people's male and female friends (80 % , individual teachers if they've become close (65 %, a spouse (50% and a co-worker (42 %. When considering the development of a tutor-student relationship, the basis was knowledge and expertise of the other person (29 % of replies, moreover personal characteristics of a tutor were underlined (71 %. The research also revealed that only certain people can assume a role of a tutor. As a single, most important characteristic the following were selected: has the ability to listen, is emphatic and tolerant to the other person. Everybody,without exception selected these characteristics. The second characteristic (53 %, but of a much lesser importance than the first one was: friendly, likeable, amicable, warm, nice, humane. It is of equal importance for a tutor to be open, honest and broad-minded. Everybody believes they could successfully develop (or have successfully developed if being (having been engaged in a relationship with such a tutor.

    Full Text Available Intelligent Tutoring Systems (ITS is an act of impacting knowledge while computer teaches or acts as the tutors which is a supplement to human teachers. The ability to teach each student based on their individual abilities a major advantage posed by ITS and that is why it is being embraced in this work. This work describes the design of an Intelligent Tutoring System that was tagged Scholastic tutor (St*, which has the individual learning and collaborative problem-solving modules. The individual tutoring module was designed to provide appropriate lessons to individuals based on his/her background knowledge level, interest, and learning style and assimilation rate prior to using the tutoring system. A software agent is used to monitor and process these parameters, arrange the learning topic, and exercises, for each individual. The collaborative problem-based tutoring module was designed to present tutorial problems and provides facilities to assist learners with some useful information and advice for problem solving. This is because the present lecturing methodology which is the conventional teaching methodology provides an interactive classroom setting that promotes the open exchange of ideas and allows for the lecturer to communicate directly with the students but has a great disadvantage of not teaching all the students according to their own learning rate and pace. The intelligent tutor solves this problem by providing individualised learning for each student where they can learn according to their own pace and learning abilities it will provide remedy and advice when learners encounter difficulties during learning session. The classical model of ITS architecture has four main modules; domain model, student model, tutoring model and the user interface model.

    Juvenile localized scleroderma (LS) is a chronic inflammatory skin disorder associated with substantial morbidity and disability. Although a wide range of therapeutic strategies has been reported in the literature, a lack of agreement on treatment specifics and accepted methods for clinical assessment has made it difficult to compare approaches and identify optimal therapy. Our objective was to develop standardized treatment plans, clinical assessments, and response criteria for active, moderate to high severity juvenile LS. A core group of pediatric rheumatologists, dermatologists, and a lay advisor was engaged by the Childhood Arthritis and Rheumatology Research Alliance (CARRA) to develop standardized treatment plans and assessment parameters for juvenile LS using consensus methods/nominal group techniques. Recommendations were validated in 2 face-to-face conferences with a larger group of practitioners with expertise in juvenile LS and with the full membership of CARRA, which encompasses the majority of pediatric rheumatologists in the US and Canada. Consensus was achieved on standardized treatment plans that reflect the prevailing treatment practices of CARRA members. Standardized clinical assessment methods and provisional treatment response criteria were also developed. Greater than 90% of pediatric rheumatologists responding to a survey (66% of CARRA membership) affirmed the final recommendations and agreed to utilize these consensus plans to treat patients with juvenile LS. Using consensus methodology, we have developed standardized treatment plans and assessment methods for juvenile LS. The high level of support among pediatric rheumatologists will support future comparative effectiveness studies and enable the development of evidence-based guidelines for the treatment of juvenile LS.

    Full Text Available Teaching online requires different skills, roles and competencies for online instructors compared to teaching in traditional learning environments. Universities should offer ongoing support in various forms to help academic staff through their online journey. This paper provides insights into a multinational faculty development program for teaching online, elaborating on results of expectancy and satisfaction surveys. From a local program to a subproject within the Swiss National Science Foundation Project Scopes, e-Tutor aimed at expanding competencies in online lecturing and providing OER material for training colleagues. Designed in the form of a descriptive case study, this research was conducted with 34 attendees of e-Tutor. Data was collected using an e-learning readiness and expectancy questionnaire, and open-ended questions after the program to measure satisfaction. Descriptive statistics were used to analyze the survey data and content analysis for open-ended data. Participants considered e-Tutor a well-planned and targeted program with good theoretical and practical balance. Duration of such courses, opportunities for adaptation to real-life situations, and localization of the content are areas to be explored further. For future studies, it would also be interesting to see whether participants can apply their newly acquired knowledge and skills to create efficient online learning environments.

    Full Text Available Abstract Background The aim of this study was to research the feasibility of training mental health consumers as tutors for 4th year medical students in psychiatry. Methods A partnership between a consumer network and an academic unit in Psychological Medicine was formed to jointly develop a training package for consumer tutors and a curriculum in interviewing skills for medical students. Student attitudes to mental health consumers were measured pre and post the program. All tutorial evaluation data was analysed using univariate statistics. Both tutors and students evaluated the teaching program using a 4 point rating scale. The mean scores for teaching and content for both students and tutors were compared using an independent samples t-test. Results Consumer tutors were successfully trained and accredited as tutors and able to sustain delivery of tutorials over a 4 year period. The study found that whilst the medical students started with positive attitudes towards consumers prior to the program, there was a general trend towards improved attitude across all measures. Other outcomes for tutors and students (both positive and negative are described. Conclusions Consumer tutors along with professional tutors have a place in the education of medical students, are an untapped resource and deliver largely positive outcomes for students and themselves. Further possible developments are described.

    1997-01-01

    The aim of this study was to develop a new method for quantitative determination of juvenile hormone (JH) based on the principle for radioimmuno assay. Using JH-binding protein (JHBP), the discrimination of the L-form of JH from D-form not occurring naturally was attempted to establish a measuring method for JH. First, the corpus allatum, the JH-producing endocrine organ was cultured and both L-form JH and 3 H or 14 C-labelled JH could be obtained easily. There are several homologs of JH and it is necessary to establish the respective labelling methods for the homologues. Since different species of insects produce JH with its specific structure, each homologue could be produced by selecting an appropriate species. The capacity of JH production was compared among five insects. The biosynthetic ability by the corpus allatum from migratory locust was highest among them and 1 μg of labelled JH type 3 could be obtained from the culture with about 50 corpus allata for 3 hrs. Since other materials than JH were also released into the culture medium, establishment of the effective method for isolation and purification of JH is necessary to use it for bioassay. (M.N.)

    2000-01-01

    This study aimed to develop a new assay method for accurate determination of juvenile hormone (JH) using radioisotope. A new measuring method for JH was designed based on the principle of molecular competition. Namely, JH-binding protein in the insect was used to form a selective binding to JH. At first, corpus allatum was cultured in a medium containing 3 H or 14 C epoxyfarnesyldiazoacetate (EFDA), which is a photoaffinity labeling reagent and JH binding protein (JHBP) was purified using 3 H or 14 C labeled EFDA. Since several kinds of JH homologues different in the molecular structure have been known, it was needed to establish each labeling method appropriate to those homologues. Then, an assay method for micro-quantitative measurement of JH was established utilizing the competition between labeled natural JH and JHBP. Thus, the authors succeeded in the overexpression of the blood JHBA of kind of tabaco moth, H.virescens and also in cloning and overexpression of JHBP in the silk worm. It was confirmed that these JHBPs specifically bind to 3 H labeled JH3, leading to stable supply of blood JHBP. Thus, accurate assay for JH concentration became possible by the use of the labeled JH with natural configuration and the blood JHBP. In the course of this study, several findings were obtained as follows: The JHBP of a sting bug was different from the previously reported ones. The regulation of JH synthesis in the corpus allatum was closely related to the control of diapause in several insects. The JHBP isolated from the cytosol of silk gland was a new protein in respect of amino acid sequence. (M.N.)

    Kashikar-Zuck, Susmita; Ting, Tracy V.

    2015-01-01

    Juvenile-onset fibromyalgia (JFM) is a poorly understood chronic pain condition most commonly affecting adolescent girls. The condition is characterized by widespread musculoskeletal pain and other associated symptoms, including fatigue, nonrestorative sleep, headaches, irritable bowel symptoms, dysautonomia and mood disorders such as anxiety and/or depression. In the past few years, there has been a greater focus on understanding JFM in adolescents. Research studies have provided insight into the clinical characteristics of this condition and its effect on both short-term and long-term psychosocial and physical functioning. The importance of early and effective intervention is being recognized, as research has shown that symptoms of JFM tend to persist and do not resolve over time as was previously believed. Efforts to improve treatments for JFM are underway, and new evidence strongly points to the potential benefits of cognitive–behavioural therapy on improving mood and daily functioning. Research into pharmacotherapy and other nonpharmacological options is in progress. Advancements in the understanding of adult fibromyalgia have paved the way for future studies on diagnosis, assessment and management of JFM. This Review focuses on our current knowledge of the condition, provides an update of the latest research advances, and highlights areas for further study. PMID:24275966

    The computer-based tutoring of visual concepts such as radiological images is a largely unexplored area. A review of the literature highlights limited use of computers as a means of radiological education, with the majority of systems being little more than hypermedia prototypes, on-line teaching files, and passive CD-Roms. Very few of the systems discussed in the research literature draw on the work from cognitive science and educational psychology for tutoring visual concepts. This thesis details and evaluates a method for indexing and retrieving images from large image databases via a cognitively informed graphical representation of visual concepts. This representation is derived using Multiple Correspondence Analysis from a statistical analysis of features present in the images. It is intended that this representation be used to assist in the computer based teaching of any discipline that requires the tutoring of visual concepts. The domain used as a test bed for this research is Magnetic Resonance Imaging in neuroradiology. Tutoring the interpretation of MR scans of the head represents a real practical problem due to the inherent complexity of the brain and variations in tissue contrast within image sequence and disease/pathology.

  1. Two approaches to physics tutoring

    Science.gov (United States)

    Solomaniuck, Tania

    One in two first-year students at science or biomedical faculties fail in basic subjects such as mathematics, chemistry or physics. Course-specific tutoring is one of the available means for improving their performance. In the present research, two tutoring models are developed. Both incorporate independent learning, but from different perspectives and priorities. A pragmatic tutoring approach. The first part of the thesis describes the search process for an optimal course-specific tutoring strategy for a standard first-year physics course in life sciences curricula. After a number of empirical research rounds, a pragmatic compromise emerged as the most suitable form of tutoring. The approach is characterised by: (1) priority to questions from students; (2) a high degree of interactivity with the tutor and among students; (3) due consideration to the number of questions to be dealt with and the depth in which they should be discussed. Most students participating in the tutoring sessions expressed their satisfaction and performed sufficiently well in their exams. However, there was still a problem: the students' insight into the course material was restricted to first-order processing of the syllabus. While this would be satisfactory in non-scientific study programmes, it is deemed insufficient in programmes where deeper insight is required in order that students be able to deal adequately with new conceptual questions or problems. In-depth tutoring. In science programmes, the core objective is for students to acquire in-depth knowledge. Therefore, science educators are designing and studying teaching methods that are geared not only to the acquisition of in-depth knowledge as such, but also to the motivation of students to take a more in-depth approach to learning. Some of the crucial notions in their research are: the extent to which the course content ties in with students' prior knowledge, problem-setting strategies and concept-context linking. 'In

    Nuclear receptor function on DNA is regulated by the balanced recruitment of coregulatory complexes. Recruited proteins that increase gene expression are called coactivators, and those that decrease gene expression are called corepressors. Little is known about the role of corepressors, such as nuclear receptor corepressor (NCoR), on the organization of behavior. We used real-time PCR to show that NCoR mRNA levels are sexually dimorphic, that females express higher levels of NCoR mRNA within the developing amygdala and hypothalamus, and that NCoR mRNA levels are reduced by estradiol treatment. To investigate the functional role of NCoR on juvenile social behavior, we infused small interfering RNA targeted against NCoR within the developing rat amygdala and assessed the enduring impact on juvenile social play behavior, sociability, and anxiety-like behavior. As expected, control males exhibited higher levels of juvenile social play than control females. Reducing NCoR expression during development further increased juvenile play in males only. Interestingly, decreased NCoR expression within the developing amygdala had lasting effects on increasing juvenile anxiety-like behavior in males and females. These data suggest that the corepressor NCoR functions to blunt sex differences in juvenile play behavior, a sexually dimorphic and hormone-dependent behavior, and appears critical for appropriate anxiety-like behavior in juvenile males and females.

    Laboratory-reared Schizothorax davidi larvae and juveniles were examined to assess the formation and characteristics of David's schizothoracin otoliths. Otolith development was observed and their formation period was verified by monitoring larvae and juveniles of known age. The results revealed that lapilli and sagittae developed before hatching, and the first otolith increment was identified at 2 days post hatching in both. The shape of lapilli was relatively stable during development compared with that of sagittae; however, growth of four sagittae and lapilli areas was consistent, but the posterior area grew faster than the anterior area and the ventral surface grew faster than the dorsal surface. Similarly, the sum length of the radius of the anterior and posterior areas on sagittae and lapilli were linearly and binomially related to total fish length, respectively. Moreover, daily deposition rates were validated by monitoring knownage larvae and juveniles. The increase in lapilli width was 1.88±0.080 0 μm at the ninth increment, which reached a maximum and the decreased gradually toward the otolith edge, whereas that of sagittae increased more slowly. These results illustrate the developmental biology of S. davidi, which will aid in population conservation and fish stock management.

    Full Text Available Modern undergraduates join science and engineering courses with poorer mathematical background than most contemporaries of the current faculty had when they were freshers. The problem is very acute in the United Kingdom but more and more countries adopt less resource intensive models of teaching and the problem spreads. University tutors and lecturers spend more and more time covering the basics. However, most of them still rely on traditional methods of delivery which presuppose that learners have a good memory and considerable time to practice, so that they can memorize disjointed facts and discover for themselves various connections between the underlying concepts. These suppositions are particularly unrealistic when dealing with a large number of undergraduates who are ordinary learners with limited mathematics background. The first author has developed a teaching system that allows such adult learners achieve relatively deep learning of mathematics – and remarkably quickly – through a teacher-guided (often called Socratic dialog, which aims at the frequent reinforcement of basic mathematical abstractions through Eulerian sequencing. These ideas have been applied to create a prototype of a Cognitive Mathematics Tutoring System aimed at teaching basic mathematics to University freshers., an electronic Personal Algebra and Calculus Tutor (e- PACT.

    Objective To explore the effects of subcutaneous microenvironment of adult rats on survival, development and androgen secretion of Leydig cells of transplanted juvenile rat testis. Methods Healthy adult SD rats were randomly divided into control group, sham group, castrated group and non-castrated group. Rats in the control group were kept intact, no testis was transplanted subcutaneously after adult recipients were castrated in the sham group; 5-7-day juvenile rat testes were transplanted subcutaneously in the castrated group, with one testis per side; Testes resected from juvenile rats were directly transplanted subcutaneously on both sides of the recipients in the non-castrated group. The grafts were obtained and weighed 4 weeks later. Then the histological features of the grafts were examined by HE staining; the expression and distribution of hydroxysteroid 17-beta dehydrogenase 1 (HSD-17β1) were investigated by immunohistochemistry; and the serum androgen level was determined by ELISA. Results The average mass of grafts obtained from the castrated group was significantly higher than that of the non-castrated group. Immunohistochemistry indicated that Leydig cells were visible in the tissues from both the castrated and non-castrated groups, but the number of HSD-17β1-posotive cells in the castrated group was larger than that in the non-castrated group. ELISA results showed that the serum androgen level was higher in the control group and non-castrated group than in the sham group and castrated group, and compared with the sham group, the serum androgen level in the castrated group was significantly higher. Conclusion The juvenile rat testis subcutaneously transplanted could further develop under the adult recipient rat skin, and the Leydig cells of grafts harbored the ability to produce and secret androgen.

  11. Increased Fos expression among midbrain dopaminergic cell groups during birdsong tutoring.

    During avian vocal learning, birds memorize conspecific song patterns and then use auditory feedback to match their vocal output to this acquired template. Some models of song learning posit that during tutoring, conspecific visual, social and/or auditory cues activate neuromodulatory systems that encourage acquisition of the tutor's song and attach incentive value to that specific acoustic pattern. This hypothesis predicts that stimuli experienced during social tutoring activate cell populations capable of signaling reward. Using immunocytochemistry for the protein product of the immediate early gene c-Fos, we found that brief exposure of juvenile male zebra finches to a live familiar male tutor increased the density of Fos+ cells within two brain regions implicated in reward processing: the ventral tegmental area (VTA) and substantia nigra pars compacta (SNc). This activation of Fos appears to involve both dopaminergic and non-dopaminergic VTA/SNc neurons. Intriguingly, a familiar tutor was more effective than a novel tutor in stimulating Fos expression within these regions. In the periaqueductal gray, a dopamine-enriched cell population that has been implicated in emotional processing, Fos labeling also was increased after tutoring, with a familiar tutor again being more effective than a novel conspecific. As several neural regions implicated in song acquisition receive strong dopaminergic projections from these midbrain nuclei, their activation in conjunction with hearing the tutor's song could help to establish sensory representations that later guide motor sequence learning.

  13. Biological therapy and development of neoplastic disease in patients with juvenile rheumatic disease: a systematic review

    Directory of Open Access Journals (Sweden)

    Vanessa Patricia L. Pereira

    Full Text Available Abstract Juvenile rheumatic diseases affect the musculoskeletal system and begin before the age of 18. These conditions have varied, identifiable or unknown etiologies, but those of an autoimmune inflammatory nature have been associated with an increased risk of development of cancer, regardless of treatment. This study aims to assess, through a systematic review of the literature according to Prisma (Preferred Reporting Items for Systematic Reviews and Meta-Analyses quality criteria, the risk of cancer in patients with juvenile rheumatic disease, and its association with biological agents. The criteria described by the Strengthening the Reporting of Observational Studies in Epidemiology initiative were used in order to assess the methodological quality of those individual items selected in this study. We analyzed nine publications, from a total of 251 papers initially selected. There was an increase in cancer risk in the population with juvenile rheumatic disease versus the general population. Most specified cancers were of a lymphoproliferative nature. Seven studies did not specify the treatment or not defined an association between treatment and cancer risk. Only one study has suggested this association; in it, their authors observed high risk in patients diagnosed in the last 20 years, a period of the advent of new therapies. One study found an increased risk in a population not treated with biological agents, suggesting a disease in its natural course, and not an adverse effect of therapy. Studies have shown an increased risk of malignancy associated with juvenile rheumatic disease, and this may be related to disease activity and not specifically to the treatment with biological agents.

  2. The effect of diet on ontogenic development of the digestive tract in juvenile reared long snout seahorse Hippocampus guttulatus.

    Palma, J; Bureau, D P; Andrade, J P

    2014-06-01

    Ontogenetic development of the digestive tract and associated organs in long snout seahorse Hippocampus guttulatus juveniles was morphologically and histologically examined from the time of release from the male's pouch until 72 h after the first meal. When released from the male's pouch, juvenile seahorses are small adult replicates. This means that unlike other teleost fish larvae, the first developmental phase has already taken place, and juveniles are morphologically prepared and able to feed on live prey immediately following parturition. At this stage, the buccopharynx, oesophagus, and intestine already appear to be fully developed. The intestine is divided into the midgut and hindgut by an intestinal valve, and intestinal villi are visible in the midgut. When fed with DHA-Selco(®) enriched Artemia, H. guttulatus juveniles developed a severe condition of overinflation of the gas bladder. The continuous overinflation of the gas bladder forced air into the gut (48 h after the first meal), resulting in overinflation of both the gut and the gas bladder (72 h after the first meal), and death occurred within 120 h after the first meal. When fed natural copepods, H. guttulatus juveniles continued a normal feeding activity with no signs of intestinal disorders, and the gas bladder and intestine maintained their normal shape. This is the first study to positively associate gas bladder overinflation of juvenile seahorses with nutritionally unbalanced diets, and not to gas supersaturation alone. It is therefore necessary to develop more adequate feed and/or enrichment products to improve the survival of juvenile seahorses in captivity.

    Schluessel, Vera; Bennett, Michael B; Bleckmann, Horst; Collin, Shaun P

    2010-04-01

    Seven elasmobranch species, a group known for their highly-developed sense of smell, were examined for developmental changes in the number of olfactory lamellae, the size of the surface area of the sensory olfactory epithelium and the mass of both the olfactory rosettes (primary input to the CNS), and the olfactory bulbs. Within each species, juveniles possessed miniature versions of the adult olfactory organs, visually not distinguishable from these and without any obvious structural differences (e.g., with respect to the number of lamellae and the extent of secondary folding) between differently sized individuals. The size of the olfactory organs was positively correlated with body length and body mass, although few species showed proportional size scaling. In Aetobatus narinari and Aptychotrema rostrata, olfactory structures increased in proportion to body size. With respect to the growth of the olfactory bulb, all species showed allometric but not proportional growth. Olfaction may be of particular importance to juveniles in general, which are often subjected to heavy predation rates and fierce inter/intraspecific competition. Accordingly, it would be advantageous to possess a fully functional olfactory system early on in development. Slow growth rates of olfactory structures could then be attributed to a greater reliance on other sensory systems with increasing age or simply be regarded as maintaining an already optimized olfactory system.

  5. Peer tutors as learning and teaching partners: a cumulative approach to building peer tutoring capacity in higher education

    Directory of Open Access Journals (Sweden)

    Sherran Clarence

    2016-06-01

    Full Text Available Peer tutors in higher education are frequently given vital teaching and learning work to do, but the training or professional development and support opportunities they are offered vary, and more often than not peer tutors are under-supported. In order to create and sustain teaching and learning environments that are better able to facilitate students’ engagement with knowledge and learning, the role of peer tutors needs to be recognised differently, as that of learning and teaching partners to both lecturers and students. Tutors then need to be offered opportunities for more in-depth professional academic development in order to fully realise this role. This paper explores a tutor development programme within a South African writing centre that aimed at offering tutors such ongoing and cumulative opportunities for learning and growth using a balanced approach, which included scholarly research and practice-based training. Using narrative data tutors provided in reflective written reports, the paper explores the kinds of development in tutors’ thinking and action that are possible when training and development is theoretically informed, coherent, and oriented towards improving practice.

    As a part of an ongoing effort to develop computerized training tools for cryosurgery, the current study presents a proof of concept for a computerized tool for cryosurgery tutoring. The tutoring system lists geometrical constraints of cryoprobes placement, simulates cryoprobe insertion, displays a rendered shape of the prostate, enables distance measurements, simulates the corresponding thermal history, and evaluates the mismatch between the target region shape and a preselected planning isotherm. The quality of trainee planning is measured in comparison with a computer-generated planning, created for each case study by previously developed planning algorithms. The following two versions of the tutoring system have been tested in the current study: (1) an unguided version, where the trainee can practice cases in unstructured sessions and (2) an intelligent tutoring system, which forces the trainee to follow specific steps, believed by the authors to potentially shorten the learning curve. Although the tutoring level in this study aims only at geometrical constraints on cryoprobe placement and the resulting thermal histories, it creates a unique opportunity to gain insight into the process outside the operation room. Post-test results indicate that the intelligent tutoring system may be more beneficial than the nonintelligent tutoring system, but the proof of concept is demonstrated with either system. © The Author(s) 2015.

    Drawing on the nationally representative "Participation and Expenditure in Education" surveys, we document the incidence and cost of private tutoring at different stages of schooling over the last two decades in India. As private tutoring involve two decisions: a) whether to take private tuition or not, and b) how much to spend on private tutoring conditional on positive decision in (a), we analyze the determinants of the two decisions separately using a Hurdle model. We find that private tut...

    Full Text Available Salmacis sphaeroides (Linnaeus, 1758 is one of the regular echinoids, occuring in the warm Indo-West Pacific, including Johor Straits, between Malaysia and Singapore. In order to investigate the developmental basis of morphological changes in embryos and larvae, we documented the ontogeny of S. sphaeroides in laboratory condition. Gametes were obtained from adult individuals by 0.5 M KCl injection into the coelomic cavity. Fertilization rate at limited sperm concentration (10−5 dilution was 96.6±1.4% and the resulting embryos were reared at 24°C. First cleavage (2-cell, 4-cell, 8-cell, 16-cell, 32-cell, and multicell (Morulla stages were achieved 01.12, 02.03, 02.28, 02.51, 03.12, and 03.32 h postfertilization. Ciliated blastulae with a mean length of 174.72±4.43 μm hatched 08.45 h after sperm entry. The gastrulae formed 16.15 h postfertilization and the archenteron elongated constantly while ectodermal red-pigmented cells migrated synchronously to the apical plate. Pluteus larva started to feed unicellular algae in 2 d, grew continuously, and finally attained metamorphic competence in 35 d after fertilization. Metamorphosis took approximately 1 h 30 min from attachment to the complete resorption of larval tissues and the development of complete juvenile structure with adult spines, extended tubefeet and well-developed pedicellaria, the whole event of which usually took place within 1 d postsettlement. This study represents the first successful investigation on embryonic, larval, and early juvenile development of S. sphaeroides. The findings would greatly be helpful towards the understanding of ontogeny and life-history strategies, which will facilitate us to develop the breeding, seed production, and culture techniques of sea urchins in captive condition.

    1987-01-01

    A series of intelligent tutoring systems, or intelligent maintenance simulators, is being developed based on expert and novice problem solving data. A graded series of authentic troubleshooting problems provides the curriculum, and adaptive instructional treatments foster active learning in trainees who engage in extensive fault isolation practice and thus in conditionalizing what they know. A proof of concept training study involving human tutoring was conducted as a precursor to the computer tutors to assess this integrated, problem based approach to task analysis and instruction. Statistically significant improvements in apprentice technicians' troubleshooting efficiency were achieved after approximately six hours of training.

  15. Premaxillary-maxillary suture asymmetry in a juvenile Gorilla. Implications for understanding dentofacial growth and development.

    Science.gov (United States)

    Schwartz, J H

    1983-01-01

    A specimen of juvenile gorilla was found that had the premaxillary-maxillary suture coursing between the lateral deciduous incisor and deciduous canine on one side of the jaw, but between the central and lateral deciduous incisors on the other; in the latter, the suture also separates the alveolus of the lateral deciduous incisor from the crypt of the growing successional lateral incisor. Rather than dismiss this exception to the traditional dictum of tooth identification--which is based on the position to teeth relative to this suture--as some inconsequential anomaly, an attempt is made to understand how this can occur within the confines of present understanding of dentofacial growth and development and developmental theory. An hypothesis relating tooth and tooth class identification is presented in the context of ectomesenchymally predifferentiated stem progenitors and subsequent tooth class proliferation.

  17. Effects of food restriction across stages of juvenile and early adult development on body weight, survival and adult life history.

    Science.gov (United States)

    Wong, J W Y; Kölliker, M

    2014-11-01

    Organisms have to allocate limited resources among multiple life-history traits, which can result in physiological trade-offs, and variation in environmental conditions experienced during ontogeny can influence reproduction later in life. Food restriction may lead to an adaptive reallocation of the limited resources among traits as a phenotypically plastic adjustment, or it can act as an overall constraint with detrimental effects throughout reproductive life. In this study, we investigated experimentally the effects of food restriction during different stages of the juvenile and early adult development on body weight, survival and reproductive success in females and males of the European earwig Forficula auricularia. Individuals either received limited or unlimited access to food across three different stages of development (fully crossed) allowing us to identify sensitive periods during development and to test both additive and interactive effects of food limitation across stages on development and reproduction. Food restriction during the early and late juvenile stage had additive negative effects on juvenile survival and adult body weight. With regard to reproductive success of females which produce up to two clutches in their lifetime, restriction specifically in the late juvenile stage led to smaller first and second clutch size, lower probability of second clutch production and reduced hatching success in the second clutch. Reproductive success of females was not significantly affected when their male mates experienced food restriction during their development. Our findings in general support the 'silver-spoon' hypothesis in that food restriction during juvenile development poses constraints on development and reproduction throughout life. © 2014 European Society For Evolutionary Biology.

  20. EarthTutor: An Interactive Intelligent Tutoring System for Remote Sensing

    Bell, A. M.; Parton, K.; Smith, E.

    2005-12-01

    Earth science classes in colleges and high schools use a variety of satellite image processing software to teach earth science and remote sensing principles. However, current tutorials for image processing software are often paper-based or lecture-based and do not take advantage of the full potential of the computer context to teach, immerse, and stimulate students. We present EarthTutor, an adaptive, interactive Intelligent Tutoring System (ITS) being built for NASA (National Aeronautics and Space Administration) that is integrated directly with an image processing application. The system aims to foster the use of satellite imagery in classrooms and encourage inquiry-based, hands-on earth science scientific study by providing students with an engaging imagery analysis learning environment. EarthTutor's software is available as a plug-in to ImageJ, a free image processing system developed by the NIH (National Institute of Health). Since it is written in Java, it can be run on almost any platform and also as an applet from the Web. Labs developed for EarthTutor combine lesson content (such as HTML web pages) with interactive activities and questions. In each lab the student learns to measure, calibrate, color, slice, plot and otherwise process and analyze earth science imagery. During the activities, EarthTutor monitors students closely as they work, which allows it to provide immediate feedback that is customized to a particular student's needs. As the student moves through the labs, EarthTutor assesses the student, and tailors the presentation of the content to a student's demonstrated skill level. EarthTutor's adaptive approach is based on emerging Artificial Intelligence (AI) research. Bayesian networks are employed to model a student's proficiency with different earth science and image processing concepts. Agent behaviors are used to track the student's progress through activities and provide guidance when a student encounters difficulty. Through individual

  1. Morphological development of Anchoviella vaillanti (Steindachner, 1908 (Clupeiformes: Engraulidae larvae and early juveniles

    Directory of Open Access Journals (Sweden)

    Anailza Cristina G. da Silva

    Full Text Available The considerable similarity in the early life stages of different fish species makes egg and larvae identification in fishery biology and ichthyoplankton surveys a difficult task. Knowledge on early larval development of morphologically similar taxa and species-rich orders, such as Clupeiformes, mainly in the Neotropical fresh waters is rather limited. The aim of the present study was to describe morphological and meristic aspects of the larvae and early juveniles of Anchoviella vaillanti, an endemic species of the São Francisco River basin in Brazil. The characterization was based on an ontogenetic series of 132 individuals (1.3-51.0 mm SL. In the larval period, body varies from elongated to very elongated and the head is small, which is typical of Clupeiformes. The finfold is present beginning in the yolk-sac stage, when larvae have a large yolk sac, until the flexion stage. Pectoral fin buds are the first to form during the preflexion stage, when dorsal- and anal-fin pterygiophores and hypural bones are first visible. The total vertebra count ranges from 36 to 39 and the myomere number ranges from 31 to 45. Complete fin formation obeys the following sequence: anal and dorsal fins during flexion stage; and pectoral, pelvic and caudal fins during postflexion stage. Despite being the only freshwater clupeiform representative in the São Francisco River, A. vaillanti may occur sympatrically with A. lepidentostole in the lower stretches of the river basin. Although early larvae characteristics of A. lepidentostole are not known, its late larvae and early juveniles may be distinguished from those of A. vaillanti, by the higher number of dorsal-fin rays (15 or 16 vs. 12 or 13 in A. vaillanti, higher total vertebra count (40 vs. 37 to 40 and shorter pre-pectoral length (14 to 16 vs. 22.8 to 28.9% SL.

    2012-01-01

    High attrition rates among students in associate degree nursing programs are a concern for faculty, administrators, and students. Programs offering academic and emotional support for students at risk for failing a clinical course may decrease attrition rates and improve academic performance. A peer tutoring program was developed for returning nursing students who were unsuccessful in a previous clinical course. Peer tutors met with returning students weekly to review course work, complete case studies and practice NCLEX questions. Trusting, supportive relationships developed among students and a significant increase in grades was noted at the end of the course for 79% of students. Implementation of peer tutoring was beneficial for returning students, tutors, and the nursing program and may be valuable in other courses where academic achievement is a concern.

    Full Text Available Abstract The osteological development in Sebastes koreanus is described and illustrated on the basis of 32 larvae [6.11–11.10 mm body length (BL] and a single juvenile (18.60 mm BL collected from the Yellow Sea. The first-ossified skeletal elements, which are related to feeding, swimming, and respiration, appear in larvae of 6.27 mm BL; these include the jaw bones, palatine, opercular, hyoid arch, and pectoral girdle. All skeletal elements are fully ossified in the juvenile observed in the study. Ossification of the neurocranium started in the frontal, pterotic, and parietal regions at 6.27 mm BL, and then in the parasphenoid and basioccipital regions at 8.17 mm BL. The vertebrae had started to ossify at ~7.17 mm BL, and their ossification was nearly complete at 11.10 mm BL. In the juvenile, although ossification of the pectoral girdle was fully complete, the fusion of the scapula and uppermost radial had not yet occurred. Thus, the scapula and uppermost radial fuse during or after the juvenile stage. The five hypurals in the caudal skeleton were also fused to form three hypural elements. The osteological results are discussed from a functional viewpoint and in terms of the comparative osteological development in related species.

    Takahashi, Kohji; Masuda, Reiji; Yamashita, Yoh

    2014-03-01

    We assessed whether the development of observational learning in jack mackerel Trachurus japonicus juveniles corresponds with that of their schooling behaviour. Schooling behaviour was quantitatively analyzed by nearest neighbour distance and separation angle in two size classes of fish, 20-mm and 40-mm in body length. Observer and non-observer fish with matching sizes were conditioned to pellets by temporarily stopping aeration. Observer fish were provided with five observation trials of other individuals feeding near an air stone when aeration was stopped. After the observation trial, fish were conditioned to pellets with the stop of aeration, and then the learning process was evaluated by the increase in the association with the feeding area when aeration was stopped. In 20-mm fish, which were at an immature stage of schooling behaviour, there was no difference in the learning process between observer and non-observer fish. In contrast, 40-mm fish were confirmed to have a well-developed schooling behaviour, and the observer learnt the feeding area more efficiently than the non-observer. This study provides evidence that observational learning develops along with the development of the social interaction. Copyright © 2013 Elsevier B.V. All rights reserved.

    Full Text Available Computer-supported learning is an increasingly important form of study since it allows for independent learning and individualized instruction. In this paper, we discuss a novel approach to developing an intelligent tutoring system for teaching textbook-style mathematical proofs. We characterize the particularities of the domain and discuss common ITS design models. Our approach is motivated by phenomena found in a corpus of tutorial dialogs that were collected in a Wizard-of-Oz experiment. We show how an intelligent tutor for textbook-style mathematical proofs can be built on top of an adapted assertion-level proof assistant by reusing representations and proof search strategies originally developed for automated and interactive theorem proving. The resulting prototype was successfully evaluated on a corpus of tutorial dialogs and yields good results.

    In modern times, peer tutoring methods have been explored in health care education for over 30 years. In this paper, we report our experience of implementing a peer-tutoring approach to Clinical Skills Laboratory (CSL) training in the Graduate Entry in Medicine Programme (GEM) at University College Cork. Eighteen fourth-year medical students were recruited as peer tutors for CSL sessions on physical examination. In order to standardise the process, we developed a training course for peer tutors that comprised two stages. They then ran the practical sessions with junior students, under the watchful eye of medical educators. At the end of the last CSL session, the students were given 10 minutes to reflect individually on the experience, and were asked to complete a feedback form. Twenty-four of the 42 GEM students and six of the seven Senior Tutors (STs) completed and returned their feedback forms. With the caveats of small sample sizes and low response rates, both groups reported that they had both positive and negative experiences of peer tutoring, but that the positive experiences predominated. The overall experience was positive. In terms of the primary thesis of this study, the STs thought that they were well prepared by the teaching staff to take part in these teaching sessions. © Blackwell Publishing Ltd 2010.

    2014-11-01

    Full Text Available The Southern rock lobster, Jasus edwardsii, is a temperate species of spiny lobster with established well managed fisheries in Australia and New Zealand. It has also been under consideration as a species with aquaculture potential. Agonistic behaviour has important consequences under aquaculture conditions that encompass direct effects, such as damage or death of protagonists, and indirect effects on growth that relate to resource access, principally food and refuge. This study aimed to identify and characterize behaviours and to make a preliminary investigation of their occurrence under tank culture. Juvenile Jasus edwardsii were examined in a flow-through seawater system using a remote video camera system. Twenty-nine behaviours were divided into three sub-groups: aggressive (11, avoidance (6 and others (12. Aggressive behaviours included attacks, pushing, lifting, clasping and carrying an opponent. Avoidance behaviours included moving away in a backwards-, forwards- or side-stepping motion as well as with more vigorous tail flips. These behaviours were components of twelve behavioural groups that described contact, attack and displacement between individuals. Activity was crepuscular with two clear peaks, one in the morning and the other in the evening. The occurrence of behavioural groups was not different between the morning and evening. The frequency of aggressive behaviours was not affected by changes made to stocking density or access to food. The implications of agonistic behaviours are discussed further in relation to developing aquaculture.

    2007-05-01

    Stress is a risk factor for chronic illnesses such as obesity, type 2 diabetes, and hypertension and has been postulated to cause the metabolic syndrome via perturbation of the hypothalamo-pituitary-adrenal (HPA) axis. In our model of early-life stress (variable foraging demand [VFD]), food insecurity is imposed on monkey mothers for 16 weeks beginning when their nursing offspring are 3-5 months of age. Under VFD, food availability is never restricted, and the infant's growth is unaffected. VFD rearing does, however, cause a range of neurobiological abnormalities, including dysregulation of the HPA axis, manifested in abnormal cerebrospinal fluid cortisol and corticotropin-releasing factor levels. We previously reported spontaneous occurrence of metabolic syndrome in 14% of normally reared peripubertal bonnet macaques given ad libitum access to standard monkey chow. Here, we show that compared with normally reared monkeys, peripubertal VFD juveniles exhibit greater weight, BMI, abdominal circumference, and glucagon-like peptide-1 and decreased glucose disposal rates during hyperinsulinemic-euglycemic clamps. Our data suggest that early-life stress during a critical period of neuro development can result in the peripubertal emergence of obesity and insulin resistance.

    Full Text Available According to the temperature-size rule (TSR, ectotherms developing under cold conditions experience slower growth as juveniles but reach a larger size at maturity. Whether temperature alone causes this phenomenon is unknown, but oxygen limitation can play a role in the temperature-size relationship. Oxygen may become limited under warm conditions when the resulting higher metabolism creates a greater demand for oxygen, especially in larger individuals. We examined the independent effects of oxygen concentration (10% and 22% O2 and temperature (15 °C and 22 °C on duration of ontogenic development, which takes place within the maternal brood pouch (marsupium, and juvenile growth in the terrestrial isopod common rough woodlouse (Porcellio scaber. Individuals inside the marsupium undergo the change from the aqueous to the gaseous environment. Under hypoxia, woodlice hatched from the marsupium sooner, but their subsequent growth was not affected by the level of oxygen. Marsupial development and juvenile growth were almost three times slower at low temperature, and marsupial development was longer in larger females but only in the cold treatment. These results show that temperature and oxygen are important ecological factors affecting developmental time and that the strength of the effect likely depends on the availability of oxygen in the environment.

    Polybrominated diphenyl ethers (PBDEs) and their metabolites (e.g., hydroxylated BDEs [OH-BDEs]) are contaminants frequently detected together in human tissues and are structurally similar to thyroid hormones. Thyroid hormones partially mediate metamorphic transitions between life stages in zebrafish, making this a critical developmental window that may be vulnerable to chemicals disrupting thyroid signaling. In the present study, zebrafish were exposed to 6-OH-BDE-47 (30 nM; 15 μg/L) alone, or to a low-dose (30 μg/L) or high-dose (600 μg/L) mixture of PentaBDEs, 6-OH-BDE-47 (0.5-6 μg/L), and 2,4,6-tribromophenol (5-100 μg/L) during juvenile development (9-23 d postfertilization) and evaluated for developmental endpoints mediated by thyroid hormone signaling. Fish were sampled at 3 time points and examined for developmental and skeletal morphology, apical thyroid and skeletal gene markers, and modifications in swimming behavior (as adults). Exposure to the high-dose mixture resulted in >85% mortality within 1 wk of exposure, despite being below reported acute toxicity thresholds for individual congeners. The low-dose mixture and 6-OH-BDE-47 groups exhibited reductions in body length and delayed maturation, specifically relating to swim bladder, fin, and pigmentation development. Reduced skeletal ossification was also observed in 6-OH-BDE-47-treated fish. Assessment of thyroid and osteochondral gene regulatory networks demonstrated significantly increased expression of genes that regulate skeletal development and thyroid hormones. Overall, these results indicate that exposures to PBDE/OH-BDE mixtures adversely impact zebrafish maturation during metamorphosis. Environ Toxicol Chem 2017;36:36-48. © 2016 SETAC. © 2016 SETAC.

    Many faculties worldwide apply the method of problem-based learning (PBL) in their curricula as a form of instruction by which students in small groups develop problem-solving strategies on the basis of a specific case. This approach fosters self-responsible and context-dependent learning, which aims at providing an improved anchoring of knowledge. For this reason, the previous decades have seen a distribution of the method to medical schools across the world. The role of the tutor assumes particular importance since, in contrast to the traditional university system, he or she serves as a facilitator who fosters and structures content-related and group-dynamic learning processes. In some cases, this requires an intervention by the tutor. The major challenge is to intervene at the right time and in an appropriate manner. This paper presents examples of difficult PBL situations using short film sequences to demonstrate and comments on potential approaches of the tutor in attempting to resolve the problem. Standard problem situations within a PBL tutorial were defined and produced in a film. A collection of seven frequent critical PBL situations are presented in short film sequences. Potential instruments of intervention are demonstrated in the videos and discussed. The film sequences may be downloaded in the supplementary of the electronic version of this article (www.sciencedirect.com). Within the framework of a tutor-training programme, the problematic situations and interventions presented in this article will help to sensitise tutors to potentially critical PBL tutorial situations and aid the development of individual resolution approaches.

    Almost all medical faculties in Germany actively employ peer tutors. However, little is known about the roles these tutors play from a faculty point of view. Also, there are only few descriptions of the tutor recruitment and selection processes. 32 of the medical faculties in Germany, where tutors are used in the training of medical students, were asked to provide information on the role and recruitment of tutors by means of a partially standardized questionnaire. At the surveyed faculties (return rate 28%), tutors are mostly employed for the purpose of teaching staff support. Even though desired in individual cases, tutors rarely play an active role in curriculum- or faculty development. The way tutor recruitment is handled strongly depends on the capabilities of the individual faculties and the way tutors are utilized. In many cases this process is structured, consisting of written and oral application phases, in other cases recruitment takes place without formal application procedures. The selection criteria, however, were found to be very similar at most faculties. The role of tutors from the faculties' point of view depends strongly on the respective nature of the tutorials, which are just as diverse as the approaches to tutor recruitment. Copyright © 2017.

    Regional changes in brain stiffness were previously demonstrated in an experimental obstructive hydrocephalus juvenile rat model. The open cranial sutures in the juvenile rats have influenced brain compression and mechanical properties during hydrocephalus development and the extent by which closed cranial sutures in adult hydrocephalic rat models affect brain stiffness in-vivo remains unclear. The aims of this study were to determine changes in brain tissue mechanical properties and brain structure size during hydrocephalus development in adult rat with fixed cranial volume and how these changes were related to brain tissue deformation. Hydrocephalus was induced in 9 female ten weeks old Sprague-Dawley rats by injecting 60 μL of a kaolin suspension (25%) into the cisterna magna under anaesthesia. 6 sham-injected age-matched female SD rats were used as controls. MR imaging (9.4T, Bruker) was performed 1 day before and then at 3 days post injection. T2-weighted anatomical MR images were collected to quantify ventricle and brain tissue cross-sectional areas. MR elastography (800 Hz) was used to measure the brain stiffness (G*, shear modulus). Brain tissue in the adult hydrocephalic rats was more compressed than the juvenile hydrocephalic rats because the skulls of the adult hydrocephalic rats were unable to expand like the juvenile rats. In the adult hydrocephalic rats, the cortical gray matter thickness and the caudate-putamen cross-sectional area decreased (Spearman, P hydrocephalus is complex and is not solely dependent on brain tissue deformation. Further studies on the interactions between brain tissue stiffness, deformation, tissue oedema and neural damage are necessary before MRE can be used as a tool to track changes in brain biomechanics in hydrocephalus.

    2010-06-01

    Full Text Available Abstract Background Members of Family Nereididae have complex neural morphology exemplary of errant polychaetes and are leading research models in the investigation of annelid nervous systems. However, few studies focus on the development of their nervous system morphology. Such data are particularly relevant today, as nereidids are the subjects of a growing body of "evo-devo" work concerning bilaterian nervous systems, and detailed knowledge of their developing neuroanatomy facilitates the interpretation of gene expression analyses. In addition, new data are needed to resolve discrepancies between classic studies of nereidid neuroanatomy. We present a neuroanatomical overview based on acetylated α-tubulin labeling and confocal microscopy for post-embryonic stages of Neanthes arenaceodentata, a direct-developing nereidid. Results At hatching (2-3 chaetigers, the nervous system has developed much of the complexity of the adult (large brain, circumesophageal connectives, nerve cords, segmental nerves, and the stomatogastric nervous system is partially formed. By the 5-chaetiger stage, the cephalic appendages and anal cirri are well innervated and have clear connections to the central nervous system. Within one week of hatching (9-chaetigers, cephalic sensory structures (e.g., nuchal organs, Langdon's organs and brain substructures (e.g., corpora pedunculata, stomatogastric ganglia are clearly differentiated. Additionally, the segmental-nerve architecture (including interconnections matches descriptions of other, adult nereidids, and the pharynx has developed longitudinal nerves, nerve rings, and ganglia. All central roots of the stomatogastric nervous system are distinguishable in 12-chaetiger juveniles. Evidence was also found for two previously undescribed peripheral nerve interconnections and aspects of parapodial muscle innervation. Conclusions N. arenaceodentata has apparently lost all essential trochophore characteristics typical of

    2007-06-01

    Full Text Available Abstract Background Development of students' teaching skills is increasingly recognised as an important component of UK undergraduate medical curricula and, in consequence, there is renewed interest in the potential benefits of cross-year peer tutoring. Whilst several studies have described the use of cross-year peer tutoring in undergraduate medical courses, its use in the clinical setting is less well reported, particularly the effects of peer tutoring on volunteer tutors' views of teachers and teaching. This study explored the effects of participation in a cross-year peer tutoring programme in clinical examination skills ('OSCE tutor' on volunteer tutors' own skills and on their attitudes towards teachers and teaching. Methods Volunteer tutors were final year MBChB students who took part in the programme as part of a Student Selected Component (SSC. Tutees were year 3 MBChB students preparing for their end of year 'OSCE' examination. Pre and post participation questionnaires, including both Likert-type and open response questions, were used. Paired data was compared using the Wilcoxon signed-rank test. All tests were two-tailed with 5% significance level. Results Tutors reflected their cohort in terms of gender but were drawn from among the more academically successful final year students. Most had previous teaching experience. They were influenced to participate in 'OSCE tutor' by a desire to improve their own teaching and associated generic skills and by contextual factors relating to the organisation or previous experience of the OSCE tutor programme. Issues relating to longer term career aspirations were less important. After the event, tutors felt that participation had enhanced their skills in various areas, including practical teaching skills, confidence in speaking to groups and communication skills; and that as a result of taking part, they were now more likely to undertake further teacher training and to make teaching a major part

    2015-01-01

    As a part of an ongoing effort to develop computerized training tools for cryosurgery, the current study presents a proof-of-concept for a computerized tool for cryosurgery tutoring. The tutoring system lists geometrical constraints of cryoprobes placement, simulates cryoprobe insertion, displays a rendered shape of the prostate, enables distance measurements, simulates the corresponding thermal history, and evaluates the mismatch between the target region shape and a pre-selected planning isotherm. The quality of trainee planning is measured in comparison with a computer-generated planning, created for each case study by previously developed planning algorithms. Two versions of the tutoring system have been tested in the current study: (i) an unguided version, where the trainee can practice cases in unstructured sessions, and (ii) an intelligent tutoring system (ITS), which forces the trainee to follow specific steps, believed by the authors to potentially shorten the learning curve. While the tutoring level in this study aims only at geometrical constraints on cryoprobe placement and the resulting thermal histories, it creates a unique opportunity to gain insight into the process outside of the operation room. Posttest results indicate that the ITS system maybe more beneficial than the non-ITS system, but the proof-of-concept is demonstrated with either system. PMID:25941163

    Juvenile firesetting is a significant cause of morbidity and mortality in the United States. Male gender, substance use, history of maltreatment, interest in fire, and psychiatric illness are commonly reported risk factors. Interventions that have been shown to be effective in juveniles who set fires include cognitive behavior therapy and educational interventions, whereas satiation has not been shown to be an effective intervention. Forensic assessments can assist the legal community in adjudicating youth with effective interventions. Future studies should focus on consistent assessment and outcome measures to create more evidence for directing evaluation and treatment of juvenile firesetters. Copyright © 2016 Elsevier Inc.

    Tutoring is a useful tool in the university teaching-learning binomial, although its development is impaired in large classes. Recent improvements in information and communication technologies have made tutoring possible via the Internet. The aim of this study was to evaluate the efficacy of mixed-method academic tutoring in two basic subjects in Veterinary Science studies at the University of León (Spain) to optimize the usefulness of tutoring support in the college environment. This quasi-experimental study was firstly carried out as a pilot study in a small group of tutored students of "Cytology and Histology" (CH) (47/186; 25.3%) and "Veterinary Pharmacology" (VP) (33/141; 23.4%) subjects, and was implemented in a large class of CH the next academic year (150 students) while comparing the results with those obtained in a previous tutorless course (162 students). Tutored students were given access to online questionnaires with electronic feedback on each subject. In addition to traditional tutoring carried out in both tutored and tutorless students, the pilot study included three sessions of face-to-face tutoring in order to monitor the progress of students. Its efficacy was assessed by monitoring students' examination scores and attendance as well as a satisfaction survey. Although the examination attendance rate in the pilot study was not significantly different between tutored and tutorless groups in both subjects, an increase for numerical scores in tutored groups was observed, with a significant higher final score in VP (p = 0.001) and in the CH practice exams (first term, p = 0.009; final, p = 0.023). Good and merit scores were also better in tutored students with significant differences in VP (p = 0.005). Students felt comfortable with the tutoring service (100% in CH; 91.7% in VP). Implementation of this additional support in CH also resulted in a significant increase of attendance at the final exam in tutored courses (87.3% versus 77

  10. Embryonic, larval, and juvenile development of the sea biscuit Clypeaster subdepressus (Echinodermata: Clypeasteroida.

    Directory of Open Access Journals (Sweden)

    Bruno C Vellutini

    Full Text Available Sea biscuits and sand dollars diverged from other irregular echinoids approximately 55 million years ago and rapidly dispersed to oceans worldwide. A series of morphological changes were associated with the occupation of sand beds such as flattening of the body, shortening of primary spines, multiplication of podia, and retention of the lantern of Aristotle into adulthood. To investigate the developmental basis of such morphological changes we documented the ontogeny of Clypeaster subdepressus. We obtained gametes from adult specimens by KCl injection and raised the embryos at 26 degrees C. Ciliated blastulae hatched 7.5 h after sperm entry. During gastrulation the archenteron elongated continuously while ectodermal red-pigmented cells migrated synchronously to the apical plate. Pluteus larvae began to feed in 3 d and were 20 d old at metamorphosis; starved larvae died 17 d after fertilization. Postlarval juveniles had neither mouth nor anus nor plates on the aboral side, except for the remnants of larval spicules, but their bilateral symmetry became evident after the resorption of larval tissues. Ossicles of the lantern were present and organized in 5 groups. Each group had 1 tooth, 2 demipyramids, and 2 epiphyses with a rotula in between. Early appendages consisted of 15 spines, 15 podia (2 types, and 5 sphaeridia. Podial types were distributed in accordance to Lovén's rule and the first podium of each ambulacrum was not encircled by the skeleton. Seven days after metamorphosis juveniles began to feed by rasping sand grains with the lantern. Juveniles survived in laboratory cultures for 9 months and died with wide, a single open sphaeridium per ambulacrum, aboral anus, and no differentiated food grooves or petaloids. Tracking the morphogenesis of early juveniles is a necessary step to elucidate the developmental mechanisms of echinoid growth and important groundwork to clarify homologies between irregular urchins.

    2005-10-01

    Full Text Available In an effort to support the growing trend of the Java programming language and to promote web-based personalized education, the Java Intelligent Tutoring System (JITS was designed and developed. This tutoring system is unique in a number of ways. Most Intelligent Tutoring Systems require the teacher to author problems with corresponding solutions. JITS, on the other hand, requires the teacher to only supply the problem and problem specification. JITS is designed to "intelligently" examine the student's submitted code and determines appropriate feedback based on a number of factors such as JITS' cognitive model of the student, the student's skill level, and problem details. JITS is intended to be used by beginner programming students in their first year of College or University. This paper discusses the important aspects of the design and development of JITS, the qualitative methods and procedures, and findings. Research was conducted at the Sheridan Institute of Technology and Advanced Learning, Ontario, Canada.

    Conventional intelligent or adaptive tutoring online systems rely on domain-specific models of learner behavior based on rules, deep domain knowledge, and other resource-intensive methods. We have developed and studied a domain-independent methodology of adaptive tutoring based on domain-independent signal-processing approaches that obviate the need for the construction of explicit expert and student models. A key advantage of our method over conventional approaches is a lower barrier to entry for educators who want to develop adaptive online learning materials.

    . Juveniles lack real access to an adequate defense because they cannot afford to pay lawyers. This disconnection between rights and reality undermines the new system, raising the question of whether recent modifications to bring laws in line with international norms are in fact advancing juvenile justice. By approaching the Mexican juvenile justice systems as a single, multilayered system combining international, federal and local laws and procedures, we can better describe some of the substantive inconsistencies that continue to prevail, even as new ones develop in terms of children’s rights.

    Full Text Available Research project tutoring appears as a crucial element for teaching; it is a planned action based on the relationship between a tutor and a student. This paper presents the findings of a design and development research which has as its main aim to create an organization system for the tutoring of online research projects. That system seeks to facilitate the tutoring and supervision task with trainee researchers, providing guidance for its management and instruments for its implementation. The main conclusions arising from this research derive from considering the need to offer a solution to the problem of distance research project supervision and has materialized in organization and sequencing through a model about the variables that influence the research project tutoring problem.

Black-Right-Pointing-Pointer Compared changes in testis-related transcripts with testis germ cell distribution. Black-Right-Pointing-Pointer Our study on endosulfan endorse its prompt and complete phase-out/ban. - Abstract: Endosulfan and flutamide, a widely used pesticide and a prostate cancer/infertility drug, respectively, have an increased risk of causing endocrine disruption if they reach water bodies. Though many studies are available on neurotoxicity/bioaccumulation of endosulfan and receptor antagonism of flutamide, only little is known about their impact on testicular steroidogenesis at molecular level. Sex steroids play an important role in sex differentiation of lower vertebrates including fishes. Hence, a small change in their levels caused by endocrine disruptors affects the gonadal development of aquatic vertebrates significantly. The aim of this study was to evaluate the effects of endosulfan and flutamide on testis-related transcription factor and steroidogenic enzyme genes with a comparison on the levels of androgens during critical period of catfish testicular development. We also analyzed the correlation between the above-mentioned genes and catfish gonadotropin-releasing hormone (cfGnRH)-tryptophan hydroxylase2 (tph2). The Asian catfish, Clarias batrachus males at 50 days post hatch (dph) were exposed to very low dose of endosulfan (2.5 {mu}g/L) and flutamide (33 {mu}g/L), alone and in combination for 50 days. The doses used in this study were far less than those used in the previous studies of flutamide and reported levels of endosulfan in surface water and sediments. Sampling was done at end of the treatments (100

    Tutors report difficult incidents and distressing conflicts that adversely affect learning in their problem-based learning (PBL) groups. Faculty development (training) and peer support should help them to manage this. Yet our understanding of these problems and how to deal with them often seems inadequate to help tutors. The aim of this study was to categorise difficult incidents and the interventions that skilled tutors used in response, and to determine the effectiveness of those responses. Thirty experienced and highly rated tutors in our Year 1 and 2 medical curriculum took part in semi-structured interviews to: identify and describe difficult incidents; describe how they responded, and assess the success of each response. Recorded and transcribed data were analysed thematically to develop typologies of difficult incidents and interventions and compare reported success or failure. The 94 reported difficult incidents belonged to the broad categories 'individual student' or 'group dynamics'. Tutors described 142 interventions in response to these difficult incidents, categorised as: (i) tutor intervenes during tutorial; (ii) tutor gives feedback outside tutorial, or (iii) student or group intervenes. Incidents in the 'individual student' category were addressed relatively unsuccessfully (effective 75% of the time) by response (iii). None of the interventions worked well when used in response to problems related to 'group dynamics'. Overall, 59% of the difficult incidents were dealt with successfully. Dysfunctional PBL groups can be highly challenging, even for experienced and skilled tutors. Within-tutorial feedback, the treatment that tutors are most frequently advised to apply, was often not effective. Our study suggests that the collective responsibility of the group, rather than of the tutor, to deal with these difficulties should be emphasised.

    At the onset of vocal development, both songbirds and humans produce variable vocal babbling with broadly distributed acoustic features. Over development, these vocalizations differentiate into the well-defined, categorical signals that characterize adult vocal behaviour. A broadly distributed signal is ideal for vocal exploration, that is, for matching vocal production to the statistics of the sensory input. The developmental transition to categorical signals is a gradual process during which the vocal output becomes differentiated and stable. But does it require categorical input? We trained juvenile zebra finches with playbacks of their own developing song, produced just a few moments earlier, updated continuously over development. Although the vocalizations of these self-tutored (ST) birds were initially broadly distributed, birds quickly developed categorical signals, as fast as birds that were trained with a categorical, adult song template. By contrast, siblings of those birds that received no training (isolates) developed phonological categories much more slowly and never reached the same level of category differentiation as their ST brothers. Therefore, instead of simply mirroring the statistical properties of their sensory input, songbirds actively transform it into distinct categories. We suggest that the early self-generation of phonological categories facilitates the establishment of vocal culture by making the song easier to transmit at the micro level, while promoting stability of shared vocabulary at the group level over generations.This article is part of the themed issue 'New frontiers for statistical learning in the cognitive sciences'. © 2016 The Authors.

    Background While there is an increasing pool of literature documenting the benefits of near-peer tutoring programme, little is known about the benefits for junior and senior peer tutors. Knowledge of the peer tutors' perceived benefits at different levels of seniority will aid in the development of a near-peer tutoring programme that will better fulfil both curricula and personal aspirations of near-peer tutors. We, therefore, investigated the perceived benefits of participation in a near-peer tutoring programme for junior as well as senior near-peer tutors. Methods Pre- and post-participation questionnaires were distributed to near-peer tutors after their clinical skills teaching sessions with Phase I undergraduate medical students. The Peer Tutor Assessment Instrument questionnaires were distributed to the 1) students, and to the 2) near-peer tutors (junior and senior) after each teaching and learning session for self-evaluation. Results The senior near-peer tutors felt that their participation in the programme had enhanced their skills (p=0.03). As a whole, the near-peer tutors were more motivated (Pre 5.32±0.46; Post 5.47±0.50; p=0.210) to participate in future teaching sessions but did not expect that having teaching experiences would make teaching as their major career path in the future (Pre 4.63±1.07; Post 4.54±0.98; p=0.701). The senior near-peer tutors were evaluated significantly higher by the students (p=0.0001). Students' evaluations of near-peer tutors on the domain of critical analysis was higher than self-evaluations (p=0.003). Conclusions Generally, the near-peer tutors perceived that they have benefited most in their skills enhancement and these near-peer tutors were scored highly by the students. However, senior near-peer tutors do not perceive that the programme has a lasting impact on their choice of career path.

    2012-04-01

    Full Text Available This study aims to develop and implement a tool called intelligent tutoring system in an online course to help a formative evaluation in order to improve student learning. According to Bloom et al. (1971,117 formative evaluation is a systematic evaluation to improve the process of teaching and learning. The intelligent tutoring system may provides a timely and high quality feedback that not only inform the correctness of the solution to the problem, but also informs the students about the accuracy of the response relative to their current knowledge about the solution. Constructive and supportive feedback should be given to the students to reveal the right and wrong answers immediately after taking the test. A feedback about the right answers is a form to reinforce positive behaviors. Identifying possible errors and relating them to the instruction material may help student to strengthen the content under consideration. The remedial suggestion should be given for each answer with detailed prescription with regards the materials and instructional procedures before taking next step. The main idea is to inform the students what he has learned and what he still has to learn. The open-source LMS called Moodle™ was extended to accomplish the formative evaluation, high-quality feedback, and communal knowledge presented here with a short online financial math course that is being offered at a large University in Brazil. The preliminary results shows that the intelligent tutoring system using high quality feedback helped the students to improve their knowledge about the solution to the problems based on the errors of their past cohorts. The results and suggestion for future work are presented and discussed.

    This study examined the effects of scripted peer-tutoring reading activities, with and without programmed common play-related stimuli, on social interactions between a kindergartner with autism spectrum disorder and his typically developing peer-tutoring partners during free play. A withdrawal design with multiple baselines across peers showed no effects of peer tutoring on social interactions. A withdrawal design with 1 peer and continuing baselines across the other 2 peers showed that adding play-related common stimuli to the peer-tutoring activity increased social interactions during free play.

    Although the rat is close to being the automatic choice for regulatory juvenile toxicity studies, there are several shortcomings in this model. Choosing a species should take into serious consideration the importance of gastrointestinal tract development in the period before weaning as this may have a major effect on exposure. A comparison of the anatomical changes in the stomach and small intestine of mini-pig and rat show that the mini-pig is a far closer model for man than is the rat, although there are a few unusual aspects of small intestinal development in the mini-pig. Considerations of the development of the gastrointestinal tract and choice of species have the potential to affect safety assessment and should be a prime consideration when planning an investigation.

    Avian predation of fish is suspected to contribute to the loss of out-migrating juvenile salmonids in the Yakima Basin, potentially constraining natural and artificial production. In 1997 and 1998, the Yakima/ Klickitat Fisheries Project (YKFP)--whose goal is increasing natural production within the Yakima River--initiated investigations to assess the feasibility of developing an index to avian predation of juvenile salmon within the river. This research confirmed that Ring-billed Gulls and Common Mergansers were the primary avian predators of juvenile salmon (Phinney et al. 1998), and that under certain conditions could significantly impact migrating smolt populations. Beginning in 1999, the Washington Cooperative Fish and Wildlife Research Unit (WACFWRU) was asked by the YKFP to continue development of avian consumption indices. Monitoring methods developed by Phinney et al. (1998) were adopted (with modifications) and monitoring of impacts to juvenile salmon along river reaches and at areas of high predator/prey concentrations (colloquially referred to as ''hotspots'') has continued each year through 2001. In 2001, piscivorous birds were counted from river banks at hotspots and from a raft or drift boat along river reaches. Consumption by gulls at hotspots was based on direct observations of foraging success and modeled abundance; consumption by all other piscivorous birds was estimated using published dietary requirements and modeled abundance. Seasonal patterns of avian piscivore abundance were identified, diurnal patterns of gull abundance at hotspots were identified, and predation indices were calculated for hotspots and river reaches (for both spring and summer). Changes in survey methods in 2001 included the addition of surveys in the ''Canyon'' reach during spring and altering the method of directly measuring gull feeding rates at hotspots. Primary avian predators in 2001 were &apos

    Full Text Available Treatment of patients with severe clinical course of juvenile rheumatoid arthritis (JRA is difficult problem. During the last years genetically engineered biological drugs are used equally with traditional immunosuppressive agents in treatment of severe forms of juvenile arthritis. High effectiveness of these drugs can be accompanied with development of unfavorable effects, for example, febrile neutropenia. The article presents results of a study of effectiveness and safety of recombinant human granulocytic colony-stimulating factor — filgrastim (Leucostim — in treatment of granulocytopenia developed during immunosuppressive therapy in 16 patients with JRA. It was shown that administration of filgrastim arrests leucopenia in 100% of patients and granulocytopenia — in 93% of patients in 24 hours after first injection. High effectiveness of drug was combined with good tolerability and safety.Key words: children, treatment, granulocytopenia, filgrastim, juvenile rheumatoid arthritis.(Voprosy sovremennoi pediatrii — Current Pediatrics. – 2010;9(4:94-100

    We have developed computer-assisted speech and language tutors for deaf, hard of hearing, and autistic children. Our language-training program utilizes our computer-animated talking head, Baldi, as the conversational agent, who guides students through a variety of exercises designed to teach vocabulary and grammer, to improve speech articulation, and to develop linguistic and phonological awareness. Baldi is an accurate three-dimensional animated talking head appropriately aligned with either synthesized or natural speech. Baldi has a tongue and palate, which can be displayed by making his skin transparent. Two specific language-training programs have been evaluated to determine if they improve word learning and speech articulation. The results indicate that the programs are effective in teaching receptive and productive language. Advantages of utilizing a computer-animated agent as a language tutor are the popularity of computers and embodied conversational agents with autistic kids, the perpetual availability of the program, and individualized instruction. Students enjoy working with Baldi because he offers extreme patience, he doesn't become angry, tired, or bored, and he is in effect a perpetual teaching machine. The results indicate that the psychology and technology of Baldi holds great promise in language learning and speech therapy. [Work supported by NSF Grant Nos.

    2010-05-01

    Elementary school students often misinterpret the equal sign (=) as an operational rather than a relational symbol. Such misunderstanding is problematic because solving equations with missing numbers may be important for higher-order mathematics skills including word problems. Research indicates equal-sign instruction can alter how typically-developing students use the equal sign, but no study has examined effects for students with mathematics difficulty (MD) or how equal-sign instruction contributes to word-problem skill for students with or without MD. The present study assessed the efficacy of equal-sign instruction within word-problem tutoring. Third-grade students with MD (n = 80) were assigned to word-problem tutoring, word-problem tutoring plus equal-sign instruction (combined) tutoring, or no-tutoring control. Combined tutoring produced better improvement on equal sign tasks and open equations compared to the other 2 conditions. On certain forms of word problems, combined tutoring but not word-problem tutoring alone produced better improvement than control. When compared at posttest to 3(rd)-grade students without MD on equal sign tasks and open equations, only combined tutoring students with MD performed comparably.

    Private tutoring is a common and worldwide phenomenon. However, there is a dearth of up-to-date research on private tutoring compared with that on institutional one-to-one teaching, which could be explained by challenges associated with data collection. This article proposes using publicly available online advertisements of private tutors as a…

  6. Significance of Selective Predation and Development of Prey Protection Measures for Juvenile Salmonids in the Columbia and Snake River Reservoirs: Annual Progress Report, February 1991-February 1992.

    Poe, Thomas P.

    1992-12-31

    This document is the 1991 annual report of progress for the Bonneville Power Administration (BPA) research Project conducted by the US Fish and Wildlife Service (FWS). Our approach was to present the progress achieved during 1991 in a series of separate reports for each major project task. Each report is prepared in the format of a scientific paper and is able to stand alone, whatever the state of progress or completion. This project has two major goals. One is to understand the significance of selective predation and prey vulnerability by determining if substandard juvenile salmonids (dead, injured, stressed, diseased, or naive) are more vulnerable to predation by northern squawfish, than standard or normal juvenile salmonids. The second goal is to develop and test prey protection measures to control predation on juvenile salmonids by reducing predator-smolt encounters or predator capture efficiency.

    Full Text Available The aim of this article is to evaluate the perception of the alumni on tutoring in a public university in Mexico to analyze the way tutoring has contributed to the integral development of students. A questionnaire was applied to a sample of 312 students; the data obtained were analyzed with the IBM SPSS software. In the results, it was found that the students perceive positively the professors’ competences for tutoring. However, just over 50% of the students feel satisfied with the assigned tutor; in so far as 60% consider that their tutor canalize them to regularization courses; in addition, only 50% admit to have a major and life project, also half of the students believe that tutoring has supported to increase their performance and integration to university; and only two thirds think that their professor has pedagogic knowledge. In conclusion, the data indicate that it must be worked on the implementation of educational policies which contribute to strengthen tutoring programs that encourage the youth in Mexico to successfully complete school, thus, prevent scholar underachievement.

    Full Text Available Abstract: This study aimed to identify the most influential theory of learning related to the practice of mentoring from behaviorism, cognitivism, humanism, the sociocultural theory and connectivism, and apply the most appropriate theories to solve common problems in distance education. For this purpose, we used the literature method. It was noted that each of the theories end up being influential to the role of tutor. Therefore, the learning tends to be richer in the ratio and effective to apply different theories together. However, that support better substantiating tutor's role is humanism, the sociocultural theory and connectivism. It was noticed that the problems often experienced by students in distance education are due to failures tutor interaction and affection, implying to resolve them closer tutor with the student to have more responsibility in the exchange of information, meeting deadlines and clarity in the disclosure notes assessments. Knowledge are mainly from humanism and sociocultural theory that end up not only reasons for existence of the tutor as serving to improve the development of the quality of tutor-student interaction. Keywords: learning theories; distance learning (DL; tutor distance.

    2014-01-01

    Aim: To explore the experiences of students and tutors who participated in a residential multi-cultural and multi-professional 3 week summer school event (OPTIMAX). Method: A grounded theory approach was adopted. Two semi-structured focus group interviews (student and tutor) were conducted to explore participant experiences. Both focus groups were audio recorded and then transcribed and coded to identify the main themes and draw conclusions. Results: Inductive coding defined categories and sub-categories to explore the relationships within and between the two sets of focus group data. Discussion: OPTIMAX was seen a positive experience by both students and tutors and provided an opportunity to undertake team learning with peers from different countries or professional backgrounds. However, consideration needs to be given to team size and tutor leadership. Summary: By participating with international collaborative projects such as this, there is an opportunity to develop learning and explore current practices within radiography. - Highlights: • We explored the experiences of students and tutors during a summer school event. • This was a multi-cultural and multi-professional event. • It was found to be a valuable learning experience by both students and tutors. • Key to this was collaborative team learning by students. • However, consideration needs to be given to team size and tutor leadership

    Avian predation of fish is suspected to contribute to the loss of juvenile spring chinook salmon in the Yakima Basin, potentially constraining natural production. In 1997 and 1998, the Yakama/Klickitat Fisheries Project (YKFP) and the Washington Department of Fish and Wildlife (WDFW)--whose goal is to increase natural production historically present within the Yakima River--initiated investigations to assess the feasibility of developing an index to avian predation of juvenile salmon within the river. This research--conducted by Dr. Steve Mathews and David Phinney of the University of Washington--confirmed that Ring-billed Gulls and Common Mergansers were the primary avian predators of juvenile salmon, and that under certain conditions could impact migrating smolt populations. Beginning in 1999, the Washington Cooperative Fish and Wildlife Research Unit (WACFWRU) was asked by the YKFP and the WDFW to continue development of avian consumption indices. Monitoring methods developed by Phinney et al. (1998) were adopted (with modifications) and monitoring of impacts to juvenile salmon along river reaches and at areas of high predator/prey concentrations (colloquially referred to as ''hotspots'') continued through 2000. In 2000, piscivorous birds were counted from river banks at hotspots and from a raft or drift boat along river reaches. Consumption by gulls at Hotspots was based on direct observations of foraging success and modeled abundance; consumption by all other piscivorous birds was estimated using published dietary requirements and modeled abundance. Further development of the avian consumption index model provided an estimation of smolt consumption for the 2000 survey season. Seasonal patterns of avian piscivore abundance were identified, diurnal patterns of gull abundance at hotspots were identified, predation indices were calculated for hotspots and spring and summer river reaches, and the efficacy of aerial surveys for estimating bird

New efforts initiated in 1999 included piscivorous bird surveys at smolt acclimation sites operated by the Yakama Nation, monitoring of the North Fork Teanaway River for changes in avian piscivore abundance associated with the installation of the Jack Creek acclimation facility, and aerial surveys seeking to identify avian piscivores along the length of the Yakima River. In 1999, piscivorous birds were counted from river banks at hotspots and from a raft or drift boat along river reaches. Consumption by gulls was based on direct observations of foraging success and modeled abundance; consumption by Common Mergansers (which forage underwater) was estimated using published dietary requirements and modeled abundance.

    1990-01-01

    HyperCard is a popular hypertext-like system used for building user interfaces to databases and other applications, and CLIPS is a highly portable government-owned expert system shell. We developed HyperCLIPS in order to fill a gap in the U.S. Army's computer-based instruction tool set; it was conceived as a development environment for building adaptive practical exercises for subject-matter problem-solving, though it is not limited to this approach to tutoring. Once HyperCLIPS was developed, we set out to implement a practical exercise prototype using HyperCLIPS in order to demonstrate the following concepts: learning can be facilitated by doing; student performance evaluation can be done in real-time; and the problems in a practical exercise can be adapted to the individual student's knowledge.

    Vogel, Gila; Fresko, Barbara; Wertheim, Cheruta

    2007-01-01

    Peer tutoring is a commonly provided support service for students with learning disabilities (LD) in institutions of higher education. A large-scale survey was conducted to evaluate the PERACH peer tutoring project for students with LD at 25 universities, regional colleges, and teacher training colleges in Israel. The purpose of the study was to understand the tutoring process from the point of view of both tutees and tutors with respect to 5 main areas: tutees' needs, focus of tutoring activities, difficulties surrounding the tutoring endeavor, importance of similar study experiences, and satisfaction with the project. It is our supposition that major discrepancies in perceptions are likely to undermine the effectiveness of the tutoring. Similarities and differences in perceptions were identified, and implications that can be useful in guiding service providers are discussed.

  20. Conversation as Academic Practice: Tutors' Strategies in Integrating Student Learning in a Professional Training Degree Programme

    Directory of Open Access Journals (Sweden)

    Matt Bowden

    2013-04-01

    Full Text Available Tutors are generally considered to be an additional resource in teaching and learning, as a means of augmenting that of the lecturer. This article explores tutors as academic staff with responsibilities for developing practice competencies and integrating student learning in a social care professional training degree programme. The research is small-scale, based upon data from a purposive sample of five interviews; and upon insider-participant observation notes and reflections in one single setting. The author deployed a situated ethnographic methodology alongside a frame analytic approach. The research found that in their academic practice, tutors reveal how their student contact is oriented to developing a reflective practitioner and they discuss how programme inputs impact on the student’s professional self. Simultaneously, tutors seek to create cross programme integration through finding overlaps with academic programme strands.

  12. Medical faculty opinions of peer tutoring.

    Science.gov (United States)

    Rudland, Joy R; Rennie, Sarah C

    2014-01-01

    Peer tutoring is a well-researched and established method of learning defined as 'a medical student facilitating the learning of another medical student'. While it has been adopted in many medical schools, other schools may be reluctant to embrace this approach. The attitude of the teaching staff, responsible for organizing and or teaching students in an undergraduate medical course to formal peer teaching will affect how it is introduced and operationalized. This study elicits faculty opinions on how best to introduce peer tutoring for medical students. Structured telephone interviews were recorded, transcribed and analyzed using thematic analysis. The interviews were with medically qualified staff responsible for organizing or teaching undergraduate medical students at a New Zealand medical school. Six questions were posed regarding perceived advantages and disadvantages of peer tutoring and how the school and staff could support a peer-tutoring scheme if one was introduced. Staff generally supported the peer tutoring concept, offering a safe environment for learning with its teachers being so close in career stage to the learners. They also say disadvantages when the student-teachers imparted wrong information and when schools used peer tutoring to justify a reduction in teaching staff. Subjects felt that faculty would be more accepting of peer tutoring if efforts were made to build staff 'buy in' and empowerment, train peer tutors and introduce a solid evaluation process. Staff of our school expressed some concerns about peer tutoring that are not supported in the literature, signaling a need for better communication about the benefits and disadvantages of peer tutoring.

    Salisbury, Emily J; Dabney, Jonathan D; Russell, Kelli

    2015-04-01

    Identifying victims of commercial sexual exploitation in the juvenile justice system is a challenging complexity requiring concerted organizational commitment. Using a three-tiered, trauma-informed screening process, a 3½-month pilot intervention was implemented in Clark County Juvenile Court (Washington) to identify victims in an effort to connect them to community youth advocates and sexual assault resources. A total of 535 boys and girls ages 9 to 19 were screened during intake; 47 of these youth reported risk factors associated with commercial sexual exploitation of children (CSEC) and were subsequently referred to community advocates. Six youth (all girls) were confirmed CSEC victims and were successfully diverted from juvenile detention. Study results suggest that despite the lack of reliable data surrounding the prevalence of CSEC, juvenile justice agencies need to become educated on the risk factors to triage victims to services. © The Author(s) 2014.

    2016-03-01

    Juvenile hormone analog (JHA) insecticides are biological and structural mimics of JH, a key insect developmental hormone. Toxic and anti-developmental effects of the JHA insecticides methoprene, fenoxycarb, and pyriproxyfen were investigated on the larval and pupal stages of Spodoptera littoralis and Spodoptera frugiperda. Bioassays showed that fenoxycarb has the highest toxicity and fastest speed of kill in 2nd instar S. littoralis. All three JHAs affected the development of 6th instar (i.e., final instar) and pupal S. frugiperda. JH esterase (JHE) is a critical enzyme that helps to regulate JH levels during insect development. JHE activity in the last instar S. littoralis and S. frugiperda was 11 and 23 nmol min(-1) ml(-1) hemolymph, respectively. Methoprene and pyriproxyfen showed poor inhibition of JHE activity from these insects, whereas fenoxycarb showed stronger inhibition. The inhibitory activity of fenoxycarb, however, was more than 1000-fold lower than that of OTFP, a highly potent inhibitor of JHEs. Surprisingly, topical application of methoprene, fenoxycarb or pyriproxyfen on 6th instars of S. littoralis and S. frugiperda prevented the dramatic reduction in JHE activity that was found in control insects. Our findings suggest that JHAs may function as JH agonists that play a disruptive role or a hormonal replacement role in S. littoralis and S. frugiperda. Copyright © 2015 Elsevier B.V.

    Full Text Available The aim of the research is intelligent tutoring system for planning and development of individual learning programs for students. One of the important components of modern training programs is the individual practice programs that are formed from the first course and built up in the process of learning in the subsequent courses. Each individual practice program is formed on the basis of the Working program of practice for a specific group. At later practice stages planning and adjustment of the individual program are worked out for a particular student.The agent-oriented approach for the planning of individual learning programs is used for the formation of individual practice program. Agents of the intelligent learning systems are created according to the requirements of service-oriented architecture. To apply knowledge there used an integrated approach to represent knowledge.As a result of research, the authors propose the architecture of intelligent educational systems of the University Department, using the repository of learning objects, telecommunication systems and such agents as: the learner, the assessment of the student’s knowledge, the formation of individual programs for learning, the personal learning environment, the methodical support, the businesses. The authors demonstrate the possibility for the formation of individual practice programs using an agent of the methodical support.Application of the approaches and technologies which were considered in the article will allow to solve problems of the formation of individual practice programs. The use of such applications will extend the possibilities of intelligent tutoring systems of the University departments.

    Brei-Crawley, M. Jo

    This teacher research study examined an after-school science program called SSTAR (Science Students Teaching as Resources) to determine if this program encourages early scientific involvement for girls, specifically the investigation of simple machines. SSTAR's overall goal was to develop scientific skills in fourth grade tutors who were partnered with second grade tutees. This study was conducted during two different SSTAR study sessions, identified as the pilot study (year one) and the expanded study (year two). The SSTAR program and the data collection instruments were refined and modified during this two-year process. Four data collection instruments were used to gather data and insights into this program; video-taped interactions between tutor and tutee, a writing assessment, a performance assessment and focus group discussions. The video taped partnership interactions found that tutors used similar instructional strategies and tutees gave similar response strategies. However, these strategies varied according to the gender of the partner. A written assessment, in the form of an open ended question was given to just the tutors at the beginning and end of their session. Additionally, a performance assessment was given. This assessment asked the tutors to construct a machine from the Legos(c) that were provided. This assessment was also done in a pretest/post-test format. Scores from the writing and performance assessment were then compared and the performance assessment showed more tutor growth in knowledge of simple machines than the writing assessment. Overall students made comments stating they enjoyed the SSTAR program and would sign up again. They had no preference for a same gender or opposite gender partner among either tutor or tutee discussions. All the data examined shows evidence that SSTAR was an effective program for tutor growth in the scientific area of simple machines. While the original study focus was specifically on girls, both genders

    Tutors in a Problem-Based Learning (PBL) curriculum are thought to play active roles in guiding students to develop frameworks for use in the construction of knowledge. This implies that both subject-matter expertise and the ability of tutors to facilitate the learning process must be important in helping students learn. This study examines the behavioural effects of tutors in terms of subject-matter expertise, social congruence and cognitive congruence on students' learning process and on their final achievement. The extent of students' learning at each PBL phase was estimated by tracking the number of relevant concepts recalled at the end of each learning phase, while student achievement was based on students' ability to describe and elaborate upon the relationship between relevant concepts learned. By using Analysis of Covariance, social congruence of the tutor was found to have a significant influence on learning in each PBL phase while all of the tutor-related behaviours had a significant impact on student achievement. The results suggest that the ability of tutors to communicate informally with students and hence create a less threatening learning environment that promotes a free flow exchange of ideas, has a greater impact on learning at each of the PBL phases as compared to tutors' subject-matter expertise and their ability to explain concepts in a way that is easily understood by students. The data presented indicates that these tutor-related behaviours are determinants of learning in a PBL curriculum, with social congruence having a greater influence on learning in the different PBL phases.

    Forkhead box O (FOXO) functions as the terminal transcription factor of the insulin signaling pathway and regulates multiple physiological processes in many organisms, including lifespan in insects. However, how FOXO interacts with hormone signaling to modulate insect growth and development is largely unknown. Here, using the transgene-based CRISPR/Cas9 system, we generated and characterized mutants of the silkworm Bombyx mori FOXO ( BmFOXO ) to elucidate its physiological functions during development of this lepidopteran insect. The BmFOXO mutant (FOXO-M) exhibited growth delays from the first larval stage and showed precocious metamorphosis, pupating at the end of the fourth instar (trimolter) rather than at the end of the fifth instar as in the wild-type (WT) animals. However, different from previous reports on precocious metamorphosis caused by juvenile hormone (JH) deficiency in silkworm mutants, the total developmental time of the larval period in the FOXO-M was comparable with that of the WT. Exogenous application of 20-hydroxyecdysone (20E) or of the JH analog rescued the trimolter phenotype. RNA-seq and gene expression analyses indicated that genes involved in JH degradation but not in JH biosynthesis were up-regulated in the FOXO-M compared with the WT animals. Moreover, we identified several FOXO-binding sites in the promoter of genes coding for JH-degradation enzymes. These results suggest that FOXO regulates JH degradation rather than its biosynthesis, which further modulates hormone homeostasis to control growth and development in B. mori In conclusion, we have uncovered a pivotal role for FOXO in regulating JH signaling to control insect development. © 2017 by The American Society for Biochemistry and Molecular Biology, Inc.

    Full Text Available This paper reviews the prevalence of girls in the U.S. juvenile justice sys- tem, compares national and international incarceration rates, and reviews the profile needs of justice-involved girls. The authors offer their Model as an example of how to develop a gender-responsive approach to girls in the justice system, including a description of how the model was operationalized in a community in the United States. Critical developments and emerg- ing opportunities for each of the Model’s components: advocacy, model programming, public education, training and technical assistance, gender responsive tools, systems accountability, and evaluation are highlighted. Lessons learned are offered as a springboard for conversations about how the international community can individually assess their needs and resources and work together to improve the response to girls. The paper concludes with recommendations for choosing, evaluating, and implementing best- practice approaches for meaningful reform.

  6. Chloroplast digestion and the development of functional kleptoplasty in juvenile Elysia timida (Risso, 1818 as compared to short-term and non-chloroplast-retaining sacoglossan slugs.

    Directory of Open Access Journals (Sweden)

    Elise Marie Jerschabek Laetz

    Full Text Available Sacoglossan sea slugs are the only metazoans known to perform functional kleptoplasty, the sequestration and retention of functional chloroplasts within their digestive gland cells. Remarkably, a few species with this ability can survive starvation periods of 3-12 months likely due to their stolen chloroplasts. There are no reports of kleptoplast transfer from mother slug to either eggs or juveniles, demonstrating that each animal must independently acquire its kleptoplasts and develop the ability to maintain them within its digestive gland. We present here an investigation into the development of functional kleptoplasty in a long-term kleptoplast retaining species, Elysia timida. Laboratory-reared juvenile slugs of different post-metamorphic ages were placed in starvation and compared to 5 known short-term retaining slug species and 5 non-retaining slug species. The subsequent results indicate that functional kleptoplasty is not performed by E. timida until after 15 days post-metamorphosis and that by 25 days, these animals outlive many of the short-term retention species. Digestive activity was also monitored using lysosomal abundance as an indicator, revealing different patterns in starving juveniles versus adults. Starved juveniles were reintroduced to food to determine any differences in digestive activity when starvation ends, resulting in an increase in the number of kleptoplasts, but no overall change in lysosomal activity. By revealing some of the changes that occur during early development in these animals, which begin as non-kleptoplast-retaining and grow into long-term retaining slugs, this investigation provides a basis for future inquiries into the origin and development of this remarkable ability.

    Nguyen, Tang-Hung; Khoo, I.-Hung

    2010-06-01

    In engineering disciplines, students usually have hard time to visualize different aspects of engineering analysis and design, which inherently are too complex or abstract to fully understand without the aid of visual explanations or visualizations. As examples, when learning materials and sequences of construction process, students need to visualize how all components of a constructed facility are assembled? Such visualization can not be achieved in a textbook and a traditional lecturing environment. In this paper, the authors present the development of a computer tutoring software, in which different visualization tools including video clips, 3 dimensional models, drawings, pictures/photos together with complementary texts are used to assist students in deeply understanding and effectively mastering materials. The paper will also discuss the implementation and the effectiveness evaluation of the proposed tutoring software, which was used to teach a construction engineering management course offered at California State University, Long Beach.

    2017-07-01

    The development of computers and artificial intelligence theory allow their application in the field of education. Intelligent tutoring systems reflect student learning styles and adapt the curriculum according to their individual needs. The building of intelligent tutoring systems requires not only the creation of suitable software, but especially the search and application of the rules enabling ICT to individually adapt the curriculum. The main idea of this paper is to attempt to specify the rules for dividing the students to systematically working students and more practically or pragmatically inclined students. The paper shows that monitoring the work of students in e-learning environment, analysis of various approaches to educational materials and correspondence assignments show different results for the defined groups of students.

    Peer tutoring programs may be one method of maintaining quality of pharmacy education in the face of growing student enrollment and a small faculty body. A critical review of the literature was performed to ascertain whether peer tutoring programs improve or maintain the academic performance of health care professional students. Various electronic databases and abstracts from past American Association of Colleges of Pharmacy's annual meetings were searched to identify pertinent research. Only those articles with quantitative data, an experimental design, and comparative statistical analysis were included for review. Most studies found that peer tutoring had a positive impact on academic performance. These results may not be readily generalizable as there were numerous methodological flaws and limited descriptions of the programs and participants. Studies with better designs and more detail are needed to answer definitively whether peer tutoring is of benefit. Details of what resources were required should be included in the study to allow the reader to determine the feasibility of the intervention.

    There is little evidence about the benefits to junior doctors of participating in teaching, or how to train doctors as teachers. We explore (through South East Scotland based teaching programmes): (a) How prepared do junior doctors feel to teach? (b) What junior doctors consider to be the main challenges of teaching? (c) What motivates the junior doctors to continue teaching, and what is the perceived impact of teaching on their professional development? 'Questionnaire 1', distributed at 'tutor training days', explored (i) attitudes towards teaching and (ii) tutors' preparedness to teach. 'Questionnaire 2', distributed after completion of a teaching programme, evaluated the tutor experience of teaching. Seventy-six per cent of tutors reported no previous teacher training; 10% were able to teach during allocated work hours. The strongest motivation for teaching was to help students with their learning and to develop teaching skills. Ninety one per cent of tutors felt more prepared to teach by the end of the programme. Tutors also improved their clinical skills from teaching. There is a body of junior doctors, who see teaching as an important part of their career, developing both teaching and clinical skills in the tutor. If teaching is expected of foundation doctors, rotas ought to be more flexible to facilitate both teaching and teacher training.

    Modern out-of-season egg production in Atlantic salmon (Salmo salar) increases the risk of postovulatory aging (POA) of oocytes. Postovulatory aging is known to influence oocyte quality in salmonids, but reliable tests for POA are lacking in Atlantic salmon egg production. To address this problem, we have collected oocytes from the same 20 Atlantic salmon females sequentially in approximately 1-week intervals, from the start of ovulation until 28 days postovulation (dpo), to determine the effect of natural retention of matured oocytes in body coelomic cavity on further performance of embryos and juveniles produced from those oocytes. Also, we investigated oocyte water hardening and several coelomic fluid parameters as potential quantitative indicators of POA. Oocyte quality decreased significantly from 22 dpo onward, as inferred from decrease in fertilization success and survival of embryos, alevins, and juveniles and increase in alevin and juvenile deformity rates. The occurrence of head deformities was significantly related to postovulatory age of oocytes. Coelomic fluid pH decreased significantly at 28 dpo and correlated positively with fertilization rates (r = 0.45), normal eyed embryo rates (r = 0.67), and alevin relative survival rates (r = 0.63) and negatively correlated with total alevin deformity rates (r = -0.59). Oocyte weight gain at 60 minutes decreased significantly at 28 dpo and correlated negatively with total alevin deformities and the occurrence of cranial nodules (r = -0.99). Generally, quality of ovulated oocytes remained stable for the first 2 weeks after ovulation. Later on, POA negatively influenced Atlantic salmon embryo, alevin, and juvenile performance. For the first time, we show a long-term effect of POA on salmonid juvenile performance. Standardized pH measurements of coelomic fluid could potentially improve embryo and juvenile production by identifying low-quality oocytes at an early stage during the production. Copyright © 2015

    To describe the experience of using self-audit (SA) as a means of accrediting family and community medicine tutors, to analyse the knowledge that the tutors have on this self-assessment methodology, and to record their opinions on this method. Retrospective descriptive study and analysis of an opinion questionnaire. Family and community medicine teaching units (TU) in Catalonia. Tutors from family and community medicine TU in Catalonia (July 2001-July 2008). Training of the tutors in SA methodology, creation of a reference group and a correction cycle. Correction by peers of the SAs performed by the tutors according to previously determined criteria and subsequent issue of a report-feedback. Self-administered questionnaire by a group of TU tutors. A total of 673 SA were performed. The most frequent topic selected was diabetes mellitus in 27.9% of cases. The overall evaluation of the SA from a methodological point of view was correct in 44.5% of cases, improvable in 45.3%, and deficient in 10.2%. A total of 300 opinion questionnaires were issued. The response rate was 151/300 (50.03%). On the question about the usefulness of the SA in professional practice, 12% considered it very useful, 56% adequate, and 32% of little use or not useful. As regards whether it was a good means for the re-accreditation or accreditation of tutors, 66% considered that it was not. A high percentage of the SAs analysed are not carried out correctly, which indicates that tutors do not know this self-assessment method very well. They consider that SAs are a useful tool for improving clinical practice, but not a good means for accreditation and re-accreditation.

    Full Text Available The article is devoted to the results of empirical studies of the experiences of guilt of juvenile offenders in the context of juvenile justice where a minor appears as the subject of legal relations. Restorative approach of juvenile justice is based on an admission of guilt to the victim. In connection with it, the research of features of the guilt of minors who have committed an offence and the conditions for the development of the subjectivity will enhance understanding of the possibilities of restorative juvenile justice system in the prevention of juvenile delinquency.Thus, the results of empirical research presented in the article are important for determining of the psychological bases of realization of rehabilitation programs in the context of juvenile justice. In particular, the results are important for the organization and conduct of psychological work to overcome the psychological barriers in the behavior of juveniles having inherently maladaptive guilt and destructive psychological defense mechanisms.

    Interest has been growing in the influence siblings may have on individual development. While mammalian research has tended to emphasize competition among siblings for essential but often limited resources such as the mother's milk, there is also evidence of mutual benefits to be had from sibling presence, most notably for altricial young in enhanced thermoregulatory efficiency. In the present study we asked whether littermates of an altricial mammal, the domestic rabbit, might gain other developmental benefits from sibling presence. From postnatal days 1 to 25 we raised rabbit pups either together with their littermates or alone except for the brief, once daily nursing characteristic of this species, while controlling for litter size and ambient nest box temperature. At weaning on Day 25 the young were then transferred to individual cages. Before weaning, we found that pups raised separately from their littermates obtained less milk, and showed lower weight gain and slower development of the ability to maintain body equilibrium than their litter-raised sibs. This was the case even though the two groups did not differ in birth weight or in the ratio of converting milk into body mass in their temperature-controlled nest boxes. Postweaning, the isolation-raised animals were also less successful in competing for food and water when tested after deprivation than their litter-raised sibs. The present study adds to the growing evidence of the influence, in this case positive, that sibs (or half sibs) may have in shaping one another's development. © 2010 Wiley Periodicals, Inc.

    Full Text Available Ontogenetic development of the immune system in crimson snapper (Lutjanus erythropterus Bloch 1790 larvae was histologically and enzymatically studied from hatch to 36 days post-hatch (DPH. Primitive hepatopancreas appeared on 2 DPH and renal tubules started hematopoiesis on 4 DPH. The spleen anlage appeared on 6 DPH and the thymus formed on 14 DPH. Total activities of superoxide dismutase (SOD, catalase (CAT, glutathione peroxidase (GPX and sodium-potassium adenosine triphosphatase (Na+ K+-ATPase gradually increased after hatch, and showed a sharp increase after 29 DPH during the transitional feeding period from Artemia to inert feed. The specific activities of SOD, CAT, and GPX showed a trend of sharp increase and reached the maximum level on 4 DPH when exogenous feeding started, except for Na+ K+-ATPase where the peak occurred on10 DPH. The specific activities of these five enzymes reached the peak during the food transition from rotifers to Artemia, but the total activity of enzymes showed an increasing trend as fish grew. The present study provides new knowledge of the development of functional enzymes relevant to fish larvae immunity, sheds light on the understanding of the change of larval health, and improves hatchery management of crimson snapper.

    Full Text Available Background: Uveitis is one of the most common extra-articular manifestations of juvenile idiopathic arthritis (JIA. Currently, the possibility of reducing the risk of uveitis in children with JIA by using methotrexate has been studied.Objective: Our aim was to analyze the results of treatment of children with JIA by studying the relation between the use of methotrexate and the risk of uveitis.Methods: A retrospective uncontrolled study. The case histories of patients with JIA who were treated for at least 2 years after the onset of the disease were studied. The results of treatment of patients who received and who did not receive methotrexate were studied (standard therapy — non-steroidal anti-inflammatory drugs and intra-articular injections of glucocorticoids. The established cases of uveitis were taken into account.Results: The study analyzed the results of observation of 281 children with JIA. In the methotrexate group, uveitis was detected in 22/191 (11.5%, and in the control group — in 42/90 (46.7% of patients (OR 6.7; 95% CI 3.7–12.3. The time period between the onset of JIA and development of uveitis in two groups under study was the same and equal to 24 (12; 67 and 17 months (7; 35, respectively (p = 0.232. Multivariate regression analysis showed that the main predictors of uveitis were oligoarticular course of JIA (HR = 1.89, positive antinuclear antibody test (HR = 2.14, onset of JIA under the age of 5 (HR = 2.56, female gender (HR = 1.82,and the absence of methotrexate in the therapy (HR = 0.24.Conclusion: The treatment with methotrexate may reduce the risk of uveitis in patients with JIA. To confirm this hypothesis, randomized studies are needed.

    In the present study, the distribution of sulphated glycosaminoglycans (GAGs) in the developing vertebral column of Atlantic salmon (Salmo salar) at 700, 900, 1100 and 1400 d° was examined by light microscopy. The mineralization pattern was outlined by Alizarin red S and soft structures by Alcian blue. The temporal and spatial distribution patterns of different types of GAGs: chondroitin-4-sulphate/dermatan sulphate, chondroitin-6-sulphate, chondroitin-0-sulphate and keratan sulphate were addressed by immunohistochemistry using monoclonal antibodies against the different GAGs. The specific pattern obtained with the different antibodies suggests a unique role of the different GAG types in pattern formation and mineralization. In addition, the distribution of the different GAG types in normal and malformed vertebral columns from 15 g salmon was compared. A changed expression pattern of GAGs was found in the malformed vertebrae, indicating the involvement of these molecules during the pathogenesis. The molecular size of proteoglycans (PGs) in the vertebrae carrying GAGs was analysed with western blotting, and mRNA transcription of the PGs aggrecan, decorin, biglycan, fibromodulin and lumican by real-time qPCR. Our study reveals the importance of GAGs in development of vertebral column also in Atlantic salmon and indicates that a more comprehensive approach is necessary to completely understand the processes involved.

    Peer-assisted learning is widely used in medical education. However, little is known about an appropriate didactic preparation for peer tutors. We herein describe the development of a focused didactic training for skills lab tutors in Internal Medicine and report on a retrospective survey about the student tutors' acceptance and the perceived transferability of attended didactic training modules. The course consisted of five training modules: 1. 'How to present and explain effectively': the student tutors had to give a short presentation with subsequent video analysis and feedback in order to learn methods of effective presentation. 2. 'How to explain precisely': Precise explanation techniques were trained by exercises of exact description of geometric figures and group feedback. 3. 'How to explain on impulse': Spontaneous teaching presentations were simulated and feedback was given. 4. 'Peyton's 4 Step Approach': Peyton's Method for explanation of practical skills was introduced and trained by the participants. 5. 'How to deal with critical incidents': Possibilities to deal with critical teaching situations were worked out in group sessions. Twenty-three student tutors participated in the retrospective survey by filling out an electronic questionnaire, after at least 6 months of teaching experience. The exercise 'How to present and explain effectively' received the student tutors' highest rating for their improvement of didactic qualification and was seen to be most easily transferable into the skills lab environment. This module was rated as the most effective module by nearly half of the participants. It was followed by 'Peyton's 4 Step Approach' , though it was also seen to be the most delicate method in regard to its transfer into the skills lab owing to time concerns. However, it was considered to be highly effective. The other modules received lesser votes by the tutors as the most helpful exercise in improving their didactic qualification for skills lab

    The Endangered Species Act requires actions that improve the passage and survival rates for migrating salmonoids and other fish species that sustain injury and mortality when passing through hydroelectric dams. To develop a low-cost revolutionary acoustic transmitter that may be injected instead of surgically implanted into the fish, one major challenge that needs to be addressed is the micro-battery power source. This work focuses on the design and fabrication of micro-batteries for injectable fish tags. High pulse current and required service life have both been achieved as well as doubling the gravimetric energy density of the battery. The newly designed micro-batteries have intrinsically low impedance, leading to significantly improved electrochemical performances at low temperatures as compared with commercial SR416 batteries. Successful field trial by using the micro-battery powered transmitters injected into fish has been demonstrated, providing an exemplary model of transferring fundamental research into practical devices with controlled qualities.

    Environmental enrichment is of great import to the emotional, intellectual, and physical development of the juvenile psittacine and their success in the human home environment. Five major types of enrichment include social, occupational, physical, sensory, and nutritional. Occupational enrichment includes exercise and psychological enrichment. Physical enrichment includes the cage and accessories and the external home environment. Sensory enrichment may be visual, auditory, tactile, olfactory, or taste oriented. Nutritional enrichment includes variations in appearance, type, and frequency of diet, and treats, novelty, and foraging. Two phases of the preadult period deserve special enrichment considerations: the development of autonomy and puberty. Copyright © 2015 Elsevier Inc. All rights reserved.

    ??-HSD2 and MR mRNA levels increased after four days in SW in both strains, whereas only the anadromous strain maintained elevated gill GR and 11??-HSD2 mRNA levels after one month in SW. The results indicate that hormones and receptors of the GH and cortisol axes are present at significantly lower levels during spring development and SW acclimation in landlocked relative to anadromous salmon. These findings suggest that attenuation of GH and cortisol axes may, at least partially, result in reduced preparatory upregulation of key gill ion-secretory proteins, possibly a result of reduced selection pressure for marine adaptations in landlocked salmon. ?? 2007 Elsevier Inc.

    E-tutoring by means of a digital portfolio offers personal guidance in a context in which regular face-to-face contact between supervisor and student is difficult. However, implementing e-tutoring in practice is not always straightforward. This article investigates the conditions for successful e-tutoring of electronic portfolios. A combination of three methods is used: our own experience with e-tutoring, interviews with 14 tutors using an e-portfolio and the answers on questionnaires by 107 students. We present 12 tips to increase the chances of successful e-tutoring when using electronic portfolios. E-tutoring by means of electronic portfolios can be a feasible alternative in contexts in which face-to-face tutoring is difficult.

  15. An intelligent tutoring system for teaching fundamental physics concepts

    1999-12-01

    Students in traditional elementary mechanics classes can master problem solving of a quantitative nature but not those of a qualitative type. Moreover, students' naive conceptions of physics remain unchanged after completing their class. A few approaches have been implemented to improve this situation however none have met with great success. Since elementary mechanics is the foundation for all of physics and it is a required course for most science majors there is a clear need to improve the instruction of the subject. To address this problem I developed a intelligent tutoring system, called the Conceptual Helper, which coaches students during homework problem solving. The tutor uses a unique cognitive based approach to teaching physics, which presents innovations in three areas. (1) The teaching strategy, which focuses on teaching those links among the concepts of the domain that are essential for conceptual understanding yet are seldom learned by the students. (2) The manner in which the knowledge is taught, which is based on a combination of effective human tutoring techniques (e.g., hinting), effective pedagogical methods (e.g., a microscopic view of matter), and less cognitively demanding approaches (e.g., anthropomorphism). (3) The way in which misconceptions are handled which uses the underlying scientific correct line of reasoning to describe to the student the phenomenon that is the basis for the misconception. From a technological point of view the Conceptual Helper was implemented as a model-tracing tutor which intervenes when students make errors and after completion of each problem, at which time the tutor scaffolds the students on post-problem reflection. The remediation is guided by probabilistic assessment of mastery and the interventions are adapted to the errors. The thesis also presents the results of the evaluation of the system which revealed that the gain scores of the experimental group were statistically significantly higher than those of

    Coaching psychology is of increasing interest to medical educators for its potential benefits as a facilitative method in problem-based learning (PBL). However, the field lacks empirical studies that explore the lived experiences of students and tutors in the PBL coaching process. This study aimed to elicit knowledge regarding medical students' and tutors' experiences and perceptions of PBL coaching in the context of Chinese undergraduate medical education. The qualitative methodology of interpretative phenomenological analysis (IPA) was employed. Participants comprised third year medical students (n=20) and PBL tutors (n=5) who have adopted a coaching approach in PBL for a semester. Semi-structured interviews were utilized to obtain a comprehensive understanding of their experiences of PBL coaching. Data analysis followed an iterative four-stage scheme of Biggerstaff and Thompson. Six main themes emerged from diverse experiences and interpretations: 1) mindsets of coaching and learning, 2) the development of learning dispositions and capacities, 3) student group collaboration, 4) tutor-student relationships, 5) personal and professional development, and 6) challenges and difficulties in implementation. It could be concluded that PBL coaching is a dynamic, facilitative process that makes a particular contribution to the learning process from psychological, emotional, and social perspectives, whilst it demonstrates significant overlaps with PBL tutoring in terms of supporting students' cognitive activities in PBL. Further research is needed to identify the barriers and challenges for medical educators to implement coaching in the PBL process.

    To explore opinions of undergraduate medical students regarding learning outcomes of the instructional strategy of Problem Based Learning (PBL). In addition their views were sought about the role of tutors and qualities of effective tutors. This was a cross-sectional, questionnaire based study which was conducted in two colleges of Medicine, Central region, Saudi Arabia during the period of 1st of April to 30(th) June 2012. One hundred seventy four undergraduate medical students participated in this study. Seventy percent of participants have indicated that PBL strategy contributed to the development of their knowledge, presentation skills, team work abilities, and accepting criticism from other colleagues. Regarding the tutors' role in PBL tutorials, majority of the participants (75%) indicated that this role is essential, nevertheless, only 58% of students indicated that this role is clear and well identified. Sixty three percent of participants preferred a member role in the PBL tutorials and 80 percent of participants preferred both content and process expert tutors in the PBL tutorials. Significant statistical difference was noted between the views of students and their schools, gender, and study phase. Majority of the participants believed that PBL had a positive impact on the development of their cognitive, personal and teamwork skills. The view of the students in this study and the available evidence suggest that tutor should have both qualities; content and process expertise, in order to have the best outcomes from the PBL tutorials.

    Full Text Available Introduction. The problems of stimulation cognitive activity and improvement of student learning motivation are of interest for many Russian and foreign researchers. One of the approaches to solve these problems, actively implemented in educational process abroad, is peer tutoring. Peer tutoring is a form of collaborative learning based on the models of student interactions organized in pairs or groups with shared roles «peer tutor- tutee».The aim of the study is to analyze effective models of peer tutoring used abroad, to develop alternate models and apply them while teaching reading and translation at foreign language lessons in non-linguistic university.Methodology and research methods. Peer tutoring is studied by using both qualitative and quantitative research methods such as data collection, analysis and generalizations along with the experiment and observation.Results and scientific novelty. As a result the peer tutoring models have been developed and implemented within the regular classroom settings while teaching reading and translation to students in non-linguistic university. The offered models of tutoring involve preparation realities of the Russian higher education institutions; meanwhile, there are no special centers of mentoring with separate teaching staff and psychologists in foreign universities. The advantages of peer tutoring over traditional forms of education and a group form of work when students solve a problem are designated, but their roles are not accurately distributed. The undertaken experiment lasted for two years, showed that peer tutoring advantages in foreign language training consist in the following: firstly, such way of lessons allows teachers to avoid time-losing monotonous reading and translations of texts discouraging students; secondly, exchanging opinions, students study each other and gain skills of estimation of personal and others' work; thirdly, interacting in pairs or small groups, pupils are more

    Cyclin-dependent kinase-like 5 (CDKL5) disorder is a severe neurodevelopmental disorder characterized by early-onset epileptic seizures, severe developmental delay, and intellectual disability. To date, no effective pharmacological treatments are available to improve the neurological phenotype that is due to mutations in the CDKL5 gene. Murine models of CDKL5 disorder have recently been generated, making the preclinical testing of pharmacological interventions possible. Using a Cdkl5 knockout (KO) mouse model, we recently demonstrated that deficiency of Cdkl5 causes defects in postnatal hippocampal development and hippocampus-dependent learning and memory. These defects were accompanied by an increased activity of GSK3β, an important inhibitory regulator of many neuronal functions. Pharmacological inhibition of GSK3β activity was able to recover hippocampal defects and cognitive performance in juvenile Cdkl5 KO mice, suggesting that GSK3β inhibitors might be a potential therapeutic option for CDKL5 disorder. As GSK3β inhibitors have been shown to have differential medication responses in young people and adults, this study was designed to examine whether GSK3β is a possible therapeutic target both in juvenile and in adult CDKL5 patients. We found that treatment with the GSK3β inhibitor Tideglusib during the juvenile period improved hippocampal development and hippocampus-dependent behaviors in Cdkl5 KO mice, while treatment later on in adulthood had no positive effects. These results suggest that pharmacological interventions aimed at normalizing impaired GSK3β activity might have different age-dependent outcomes in CDKL5 disorder. This is of utmost importance in the development of therapeutic approaches in CDKL5 patients and in the design of rational clinical trials. © 2018 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

    This paper is written to introduce a multimedia tutoring system for nondestructive testing using personal computer. Nondestructive testing, one of the chief methods for inspecting welds and many other components, is very difficult for the NDT inspectors to understand its technical basis without a wide experience. And it is necessary for considerable repeated education and training for keeping their knowledge. The tutoring system that can simulate NDT works is suggested to solve the above problem based on reasonable condition. The tutoring system shows basic theories of nondestructive testing in a book-style with video images and hyper-links, and it offers practices, in which users can simulate the testing equipment. The book-style and simulation practices provide effective and individual environments for learning nondestructive testing.

    Full Text Available Aim. We investigated perceptions of a new smartphone application (app as a learning resource. Methods. We developed TraumaTutor, an iPhone app consisting of 150 questions and explanatory answers on trauma management. This was used by 20 hospital staff that either had a special interest in managing trauma or who were studying for relevant exams, such as ATLS. A subsequent questionnaire assessed users’ experience of smartphone applications and their perceptions of TraumaTutor. Results. Of those surveyed, 85% had a device capable of running app software, and 94% of them had used apps for medical education. Specific to TraumaTutor, 85% agreed that it was pitched at the right level, 95% felt that the explanations improved understanding of trauma management, and 100% found the app easy to use. In fact, on open questioning, the clear user interface and the quality of the educational material were seen as the major advantages of TraumaTutor, and 85% agreed that the app would be a useful learning resource. Conclusions. Smartphone applications are considered a valuable educational adjunct and are commonly used by our target audience. TraumaTutor shows overwhelming promise as a learning supplement due to its immediacy, accessibility, and relevance to those preparing for courses and managing trauma.

    Collaboration is of increasing importance in medical education and medical practice. Students' and tutors' perceptions about small group learning are valuable to inform the development of strategies to promote group dynamics and collaborative learning. This study investigated medical students' and tutors' views on competencies and behaviours which promote effective learning and interaction in small group settings. This study was conducted at UNSW Australia. Five focus group discussions were conducted with first and second year medical students and eight small group tutors were interviewed. Data were transcribed verbatim and thematic analysis was conducted. Students and tutors identified a range of behaviours that influenced collaborative learning. The main themes that emerged included: respectfulness; dominance, strong opinions and openness; constructiveness of feedback; active listening and contribution; goal orientation; acceptance of roles and responsibilities; engagement and enthusiasm; preparedness; self- awareness and positive personal attributes. An important finding was that some of these student behaviours were found to have a differential impact on group interaction compared with collaborative learning. This information could be used to promote higher quality learning in small groups. This study has identified medical students' and tutors' perceptions regarding interactional behaviours in small groups, as well as behaviours which lead to more effective learning in those settings. This information could be used to promote learning in small groups.

    We examined the effects of a tutoring package (verbal modeling, prompts, and contingent praise/ Chinese conversations with the tutor) on the performance of a college student's Mandarin Chinese pronunciation. The effects of the tutoring package were analyzed using a multiple baseline design across two sets of 50 Chinese characters. The tutoring package produced improvement in the student's correct pronunciation of Chinese characters from 48% (pretutoring) to 90% (posttutoring). Results suggested that the tutoring package produced mastery pronunciation of targeted Mandarin Chinese vocalizations by a nonnative speaker.

  18. Distance learning for training business game tutors

    Mariana de Toledo Marinho

    Full Text Available Abstract This work is the result of research that proposes the incorporation of Distance Learning into a Business Game as a strategy to enhance tutor training, considering entrepreneurship difficulties faced by public school teachers. Part of the problem could be attributed to subject type, because, in general, it is not common to find entrepreneurship on school curricula. The Distance Learning (DL activities were developed using the Moodle platform and structured by topic to increase educational flexibility and achieve a better balance between individual reflection and online discussion. It was developed in four steps: course content development; course evaluation by computer technicians; restructuring the course based on course evaluation done by computer technicians and course evaluation by teachers from the public school system. A preliminary test was performed with informatics technicians to technically evaluate the learning environment. Based on this, the course was restructured, applying corrections and adjustments to improve environment usability. After corrections, a final test was conducted with public school system teachers to analyze user perception, which gave a positive result. Virtual learning environment evaluation is complex and multidisciplinary, requiring the technical knowledge of internet programming and a conceptual knowledge of education, especially in the field of learning. When the evaluation done by teachers was examined, it was found that deficiencies pointed out by computer technicians had been resolved, giving a positive rating. This current research concludes that DL can improve the use of games, because it is possible to structure the content related to the learning gaps of specific groups of students. In this respect the use of games results can guide the development of content.

    Problem-based learning (PBL) has been adopted by many medical schools as an innovative method to deliver an integrated medical curriculum since its inception at McMaster University (Dornan et al., Med Educ 39(2):163-170, 2005; Finucane et al., Med Educ 35(1):56-61, 2001; Barrows, Tutorials in problem-based learning: A new direction in teaching the health professions, 1984). The student experience in PBL has been explored in detail (Merriam, New Directions for Adult and Continuing Education 89: 3-13, 2001; Azer, Kaohsiung J Med Sci 25(5): 240-249, 2009; Boelens et al., BMC Med Ed 15(1): 84, 2015; Dolmans et al., Med Teach 24(2):173-180, 2002; Lee et al., Med Teach 35(2): e935-e942, 2013) but the tutors who facilitate PBL have valuable insight into how PBL functions and this aspect has not been extensively researched. The integrated curriculum for years 1 and 2 at the Graduate Entry Medical School at the University of Limerick is delivered though problem-based learning (PBL). This programme requires collaborative teamwork between students and the tutors who facilitate small-group tutorial sessions. All PBL tutors at GEMS are medically qualified, with the majority (68%) currently working in clinical practice. A mixed-methods approach was adopted, utilising two surveys and follow-up focus groups to fully understand the tutor experience. Thirty-three tutors took part in two online surveys with a response rate of 89%. Thirteen tutors participated in two focus groups. Descriptive analysis was completed on survey data and thematic analysis on focus group discussions which highlighted five main themes. Tutors reported challenges with managing group dynamics, development of confidence in tutoring with experience and a willingness to learn from peers to improve practice. Findings are in keeping with previously published work. Results also identified several less commonly discussed issues impacting student engagement in PBL including the use of mobile device technology

    Research Methods Tutor (RMT) is a dialogue-based intelligent tutoring system for use in conjunction with undergraduate psychology research methods courses. RMT includes five topics that correspond to the curriculum of introductory research methods courses: ethics, variables, reliability, validity, and experimental design. We evaluated the effectiveness of the RMT system in the classroom using a nonequivalent control group design. Students in three classes (n = 83) used RMT, and students in two classes (n = 53) did not use RMT. Results indicated that the use of RMT yieldedstrong learning gains of 0.75 standard deviations above classroom instruction alone. Further, the dialogue-based tutoring condition of the system resulted in higher gains than did the textbook-style condition (CAI version) of the system. Future directions for RMT include the addition of new topics and tutoring elements.

    Co-occurring ocean warming, acidification and reduced carbonate mineral saturation have significant impacts on marine biota, especially calcifying organisms. The effects of these stressors on development and calcification in newly metamorphosed juveniles (ca. 0.5 mm test diameter) of the intertidal sea urchin Heliocidaris erythrogramma, an ecologically important species in temperate Australia, were investigated in context with present and projected future conditions. Habitat temperature and pH/pCO2 were documented to place experiments in a biologically and ecologically relevant context. These parameters fluctuated diurnally up to 10 °C and 0.45 pH units. The juveniles were exposed to three temperature (21, 23 and 25 °C) and four pH (8.1, 7.8, 7.6 and 7.4) treatments in all combinations, representing ambient sea surface conditions (21 °C, pH 8.1; pCO2 397; ΩCa 4.7; ΩAr 3.1), near-future projected change (+2-4 °C, -0.3-0.5 pH units; pCO2 400-1820; ΩCa 5.0-1.6; ΩAr 3.3-1.1), and extreme conditions experienced at low tide (+4 °C, -0.3-0.7 pH units; pCO2 2850-2967; ΩCa 1.1-1.0; ΩAr 0.7-0.6). The lowest pH treatment (pH 7.4) was used to assess tolerance levels. Juvenile survival and test growth were resilient to current and near-future warming and acidification. Spine development, however, was negatively affected by near-future increased temperature (+2-4 °C) and extreme acidification (pH 7.4), with a complex interaction between stressors. Near-future warming was the more significant stressor. Spine tips were dissolved in the pH 7.4 treatments. Adaptation to fluctuating temperature-pH conditions in the intertidal may convey resilience to juvenile H. erythrogramma to changing ocean conditions, however, ocean warming and acidification may shift baseline intertidal temperature and pH/pCO2 to levels that exceed tolerance limits. © 2013 John Wiley & Sons Ltd.

    Early life nutrition is critical for brain development. Dietary prebiotics and bioactive milk fractions support brain development by increasing plasticity and altering activity in brain regions important for cognition and emotion regulation, perhaps through the gut-microbiome-brain axis. Here we examined the impact of a diet containing prebiotics, lactoferrin, and milk fat globule membrane (test diet) on beneficial gut bacteria, basal gene expression for activity and plasticity markers within brain circuits important for cognition and anxiety, and anxiety-related behavior in the open field. Juvenile male F344 rats were fed the test diet or a calorically matched control diet beginning postnatal day 24. After 4 weeks on diets, rats were sacrificed and brains were removed. Test diet significantly increased mRNA expression for cfos, brain derived neurotropic factor, and the GluN1 subunit of the NMDA receptor in the prefrontal cortex and reduced cfos mRNA within the amygdala. Diet-induced increases in fecal Lactobacillus spp., measured using selective bacterial culture, positively correlated with altered gene expression for cfos and serotonin receptors within multiple brain regions. In a separate cohort of juvenile rats, 4 weeks of the test diet increased time spent in the center of the open field, a behavior indicative of reduced anxiety. These data demonstrate that early life diets containing prebiotics and bioactive milk fractions can adaptively alter genes in neural circuits underlying emotion regulation and decrease anxiety-related behavior.

    Baudendistel, Stephen; Hua, Grace

    1987-01-01

    The interface between an Intelligent Tutoring System (ITS) and the person being tutored is critical to the success of the learning process. If the interface to the ITS is confusing or non-supportive of the tutored domain, the effectiveness of the instruction will be diminished or lost entirely. Consequently, the interface to an ITS should be highly integrated with the domain to provide a robust and semantically rich learning environment. In building an ITS for ZetaLISP on a LISP Machine, a Desktop Interface was designed to support a programming learning environment. Using the bitmapped display, windows, and mouse, three desktops were designed to support self-study and tutoring of ZetaLISP. Through organization, well-defined boundaries, and domain support facilities, the desktops provide substantial flexibility and power for the student and facilitate learning ZetaLISP programming while screening the student from the complex LISP Machine environment. The student can concentrate on learning ZetaLISP programming and not on how to operate the interface or a LISP Machine.

    Peer tutoring has been described as "people from similar social groupings who are not professional teachers helping each other to learn and learning themselves by teaching". Peer tutoring is well accepted as a source of support in many medical curricula, where participation and learning involve a process of socialisation. Peer tutoring can ease the transition of the junior students from the university class environment to the hospital workplace. In this paper, we apply the Experienced Based Learning (ExBL) model to explore medical students' perceptions of their experience of taking part in a newly established peer tutoring program at a hospital based clinical school. In 2014, all students at Sydney Medical School - Central, located at Royal Prince Alfred Hospital were invited to voluntarily participate in the peer tutoring program. Year 3 students (n = 46) were invited to act as tutors for Year 1 students (n = 50), and Year 4 students (n = 60) were invited to act as tutors for Year 2 students (n = 51). Similarly, the 'tutees' were invited to take part on a voluntary basis. Students were invited to attend focus groups, which were held at the end of the program. Framework analysis was used to code and categorise data into themes. In total, 108/207 (52 %) students participated in the program. A total of 42/106 (40 %) of Year 3 and 4 students took part as tutors; and of 66/101 (65 %) of Year 1 and 2 students took part as tutees. Five focus groups were held, with 50/108 (46 %) of students voluntarily participating. Senior students (tutors) valued the opportunity to practice and improve their medical knowledge and teaching skills. Junior students (tutees) valued the opportunity for additional practice and patient interaction, within a relaxed, small group learning environment. Students perceived the peer tutoring program as affording opportunities not otherwise available within the curriculum. The peer teaching program provided a framework within the

  10. An Intelligent and Interactive Simulation and Tutoring Environment for Exploring and Learning Simple Machines

    Science.gov (United States)

    Myneni, Lakshman Sundeep

    Students in middle school science classes have difficulty mastering physics concepts such as energy and work, taught in the context of simple machines. Moreover, students' naive conceptions of physics often remain unchanged after completing a science class. To address this problem, I developed an intelligent tutoring system, called the Virtual Physics System (ViPS), which coaches students through problem solving with one class of simple machines, pulley systems. The tutor uses a unique cognitive based approach to teaching simple machines, and includes innovations in three areas. (1) It employs a teaching strategy that focuses on highlighting links among concepts of the domain that are essential for conceptual understanding yet are seldom learned by students. (2) Concepts are taught through a combination of effective human tutoring techniques (e.g., hinting) and simulations. (3) For each student, the system identifies which misconceptions he or she has, from a common set of student misconceptions gathered from domain experts, and tailors tutoring to match the correct line of scientific reasoning regarding the misconceptions. ViPS was implemented as a platform on which students can design and simulate pulley system experiments, integrated with a constraint-based tutor that intervenes when students make errors during problem solving to teach them and to help them. ViPS has a web-based client-server architecture, and has been implemented using Java technologies. ViPS is different from existing physics simulations and tutoring systems due to several original features. (1). It is the first system to integrate a simulation based virtual experimentation platform with an intelligent tutoring component. (2) It uses a novel approach, based on Bayesian networks, to help students construct correct pulley systems for experimental simulation. (3) It identifies student misconceptions based on a novel decision tree applied to student pretest scores, and tailors tutoring to

    Objective: Peer-assisted learning is widely used in medical education. However, little is known about an appropriate didactic preparation for peer tutors. We herein describe the development of a focused didactic training for skills lab tutors in Internal Medicine and report on a retrospective survey about the student tutors’ acceptance and the perceived transferability of attended didactic training modules. Methods: The course consisted of five training modules: ‘How to present and explain effectively’: the student tutors had to give a short presentation with subsequent video analysis and feedback in order to learn methods of effective presentation. ‘How to explain precisely’: Precise explanation techniques were trained by exercises of exact description of geometric figures and group feedback. ‘How to explain on impulse’: Spontaneous teaching presentations were simulated and feedback was given. ‘Peyton’s 4 Step Approach’: Peyton‘s Method for explanation of practical skills was introduced and trained by the participants. ‘How to deal with critical incidents’: Possibilities to deal with critical teaching situations were worked out in group sessions. Twenty-three student tutors participated in the retrospective survey by filling out an electronic questionnaire, after at least 6 months of teaching experience. Results: The exercise ‘How to present and explain effectively’ received the student tutors’ highest rating for their improvement of didactic qualification and was seen to be most easily transferable into the skills lab environment. This module was rated as the most effective module by nearly half of the participants. It was followed by ‘Peyton’s 4 Step Approach’ , though it was also seen to be the most delicate method in regard to its transfer into the skills lab owing to time concerns. However, it was considered to be highly effective. The other modules received lesser votes by the tutors as the most helpful exercise in

    Timely access to holistic multidisciplinary care is the core principle underpinning management of juvenile idiopathic arthritis (JIA). Data collected in national clinical audit programmes fundamentally aim to improve health outcomes of disease, ensuring clinical care is equitable, safe and patient-centred. The aim of this study was to develop a tool for national audit of JIA in the UK. A staged and consultative methodology was used across a broad group of relevant stakeholders to develop a national audit tool, with reference to pre-existing standards of care for JIA. The tool comprises key service delivery quality measures assessed against two aspects of impact, namely disease-related outcome measures and patient/carer reported outcome and experience measures. Eleven service-related quality measures were identified, including those that map to current standards for commissioning of JIA clinical services in the UK. The three-variable Juvenile Arthritis Disease Activity Score and presence/absence of sacro-iliitis in patients with enthesitis-related arthritis were identified as the primary disease-related outcome measures, with presence/absence of uveitis a secondary outcome. Novel patient/carer reported outcomes and patient/carer reported experience measures were developed and face validity confirmed by relevant patient/carer groups. A tool for national audit of JIA has been developed with the aim of benchmarking current clinical practice and setting future standards and targets for improvement. Staged implementation of this national audit tool should facilitate investigation of variability in levels of care and drive quality improvement. This will require engagement from patients and carers, clinical teams and commissioners of JIA services. © The Author 2017.

    Full Text Available With our busy schedules today and the rising cost of education there is a need to find a convenient and cost effective means of maximizing our educational/training experiences. New trends in the delivery/access of information are becoming more technology based in all areas of society with education being no exception. The ubiquitous use of mobile devices has led to a boom in m-commerce. Mobile devices provide many services in commercial environments such as mobile banking, mobile purchasing, mobile learning, etc. It is therefore fitting that we seek to use mobile devices as a platform in delivering our convenient and cost effective solution. The proposed agent based Mobile tutoring system seeks to provide a student with a rich learning experience that will provide them with the relevant reading material based on their stage of development which allows them to move at their own pace. The system will allow the user to be able to ask certain questions and get explanations as if they were interacting with a human tutor but with the added benefit of being able to do this anytime in any location via their mobile phone.

  2. The Learning Tutor: A Web based Authoring System to Support Distance Tutoring

    Directory of Open Access Journals (Sweden)

    Omar Abou Khaled

    2000-01-01

    Full Text Available In distance learning contexts, such as those are being widely promoted and developed with the extensive use of ICT (Information and Communication Technology some important issues have to be carefully addressed, in order to make education more effective and available. Distant students have to face sound organizational problems concerning the working time-management and the regulation of all the learning process. These are far more complex at a distance because of the difficulties to understand and objectively evaluate how the study is progressing in term of knowledge and competence acquisition, both for the students themselves and for the teacher who is supposed to adjust the teaching process in case of need. Moreover, the absence of clear indication for the student of the relative level of importance of each piece of information available comes to be another key issue in distance education. This paper describes a Web-based authoring system, the Learning Tutor, conceived to cover these issues. The environment is composed by several interconnected authoring systems: “The Course Description, the Guiding Thread and the Agenda”, “The Work Plan and Themes Reviewer”, and “The Quizzes self-evaluation facility”. This model of combined tools aims at providing the suitable support for organization, work and time management in distance learning processes using well documented mastery learning principles.

    Juvenile mammary papillomatosis is a benign proliferative disease of young patients, generally under 30 years of age. The most frequent clinical presentation is the existence of an elastic and mobile lymph node of the breast. Anatomopathologically, it is characterized because it presents ductal epithelial hyperplasia, sometimes with marked atypia, and there are numerous cysts having different sizes among the findings. It has been associated with an increase in the incidence of breast cancer, both in the patient herself as well as her family. We review the literature on the subject and present the mammographic and ultrasonographic findings of a 22 year old woman diagnosed of juvenile mammary papillomatosis. (Author) 12 refs.

A hipótese testada é que a ação do hormônio juvenil seja capaz de proteger ou prevenir a degeneração nos ovários das larvas de operárias. Foi feita aplicação tópica de 1 ml de hormônio dissolvido em hexano na concentração de 1 mg/ml do segundo até o quinto dia de vida larval, e a morfologia dos ovários avaliada nos dias subseqüentes à aplicação até ao sexto dia de vida larval. Como controles foram utilizadas larvas nas quais se aplicou 1 ml de hexano e larvas que não receberam nenhum tratamento. Constatou-se que o efeito do hormônio juvenil varia conforme a idade larval em que é aplicado e que este efeito foi maior quando a aplicação foi feita no terceiro dia de vida larval.The influence of juvenile hormone (JH on the ovarian development of worker larvae of Apis mellifera was analyzed, taking into account the trophic determination of the castes. The workers control the larval feeding in order to promote caste differentiation, which is regulated by the production and availability of this hormone. The hypothesis tested was that the action of juvenile hormone is capable of protecting or preventing the degeneration of the ovaries in worker larvae. A preparation of 1 ml of juvenile hormone dissolved in hexane at a concentration of 1 mg/ml was applied topically to 2- to 5-day-old larvae. The morphology of the ovaries was evaluated on the days following the application, until the larvae were 6 days old. The controls consisted of larvae to which 1 ml of hexane was applied, and larvae that received no treatment. The effect of juvenile hormone varied according to the age

    2006-09-01

    The present study aimed to determine the influence of thyroid status on the timing of the pubertal resurgence in gonadotrophin-releasing hormone pulse generator activity [tracked by circulating luteinising hormone (LH) levels] in male rhesus monkeys. Six juvenile monkeys were orchidectomised and then treated with the antithyroid drug, methimazole, from 15-19 months until 36 months of age, at which time thyroxine (T(4)) replacement was initiated. Four additional agonadal monkeys served as controls. Blood samples were drawn weekly for hormonal assessments. Body weight, crown-rump length and bone age were monitored at regular intervals. By 8 weeks of methimazole treatment, plasma T(4) had fallen sharply, and the decline was associated with a plasma thyroid-stimulating hormone increase. In controls, plasma LH levels remained undetectable until the pubertal rise occurred at 29.3 +/- 0.2 months of age. This developmental event occurred in only half of the methimazole-treated animals before 36 months of age when T(4) replacement was initiated. The hypothyroid state was associated with a profound arrest of growth and bone maturation, but increased body mass indices and plasma leptin levels. T(4) replacement in methimazole-treated monkeys was associated with the pubertal rise in LH in the remaining three animals and accelerated somatic development in all six animals. Although pubertal resurgence in LH secretion occurred at a later chronological age in methimazole-treated animals compared to controls, bone age, crown-rump length and body weight at that time did not differ between groups. There were no long-term differences in plasma prolactin between groups. We conclude that juvenile hypothyroidism in male primates causes a marked delay in the pubertal resurgence of LH secretion, probably occasioned at the hypothalamic level. Whether this effect is meditated by an action of thyroid hormone directly on the hypothalamus or indirectly as a result of the concomitant deficit in

    Little attention has been focused on the effect of anthropogenic compounds that disrupt the endocrine systems in crustaceans. Consequently, this study investigated the effects of the juvenile hormone analogue (JHA), Fenoxycarb on selected physiological and developmental processes of the zoeal stages in the European lobster, Homarus gammarus. Chronic exposure to Fenoxycarb (50microg L(-1)) resulted in a significant (p < 0.05) reduction in moult frequency and size at moult. Fenoxycarb exposure extended zoeal duration between zoea I to II (p<0.05) and resulted in total inhibition of the moult from zoea II to III. Significantly greater rates of O2 uptake were observed in Fenoxycarb-exposed larvae in comparison with controls (p<0.05). All rates of O2 uptake decreased significantly between 7 and 12d of exposure (p<0.05). At 12d, exposure to the solvent control no longer influenced rates of O2 uptake, but it was not possible to attribute increased O2 uptake to Fenoxycarb exposure directly, as treated individuals did not moult beyond zoea III. The low exposure concentrations of Fenoxycarb, comparable to those used in plant protection, resulted in endocrine disrupted responses in H. gammarus (albeit with little clear, demonstrable effect on metabolism) a finding that could have important ecological and commercial implications.

  10. The Advancing Potential of Tutor Technologies in the Senior Students Training in the High School

    Directory of Open Access Journals (Sweden)

    Y. A. Lyakh

    2013-01-01

    Full Text Available The paper is devoted to the tutoring system in the modern high school. The system in question is based on the complex developmental educational technology of personalized teaching, aimed at identifying students’ educational motives and interests, and creating individual training programs and educational reflection. The important role is given to the tutor’s competence both in profile teaching and creating the comfortable communicative and stimulating educational environment. The author reveals the structural and functional implementation model of tutoring technologies, and observes its performance in the course of education quality monitoring of senior students in the profile high schools. The effectiveness of the personalized tutor technology system is demonstrated in three different aspects: the students’ education quality and communicative educational activity; development of tutors’ competence in monitoring the profile education quality; and students’ self-assessment and professional self-determination. The experimental research demonstrates that the implementation model of tutor technologies facilitates education quality improvement in the high school. 

  11. Teaching the tacit knowledge of programming to noviceswith natural language tutoring

    2005-09-01

    For beginning programmers, inadequate problem solving and planning skills are among the most salient of their weaknesses. In this paper, we test the efficacy of natural language tutoring to teach and scaffold acquisition of these skills. We describe ProPL (Pro-PELL), a dialogue-based intelligent tutoring system that elicits goal decompositions and program plans from students in natural language. The system uses a variety of tutoring tactics that leverage students' intuitive understandings of the problem, how it might be solved, and the underlying concepts of programming. We report the results of a small-scale evaluation comparing students who used ProPL with a control group who read the same content. Our primary findings are that students who received tutoring from ProPL seem to have developed an improved ability to solve the composition problem and displayed behaviors that suggest they were able to think at greater levels of abstraction than students in the read-only group.

  12. The semantic sphere of juvenile offenders

    2017-01-01

    Full Text Available The article presents the results of a preliminary empirical study aimed to identify features of the semantic sphere of adolescents who have committed illegal, including aggressive acts. The study included 50 male juveniles aged of 16 - 17 years. The first group consisted of adolescents convicted of aggressive and violent crimes; the second – of property socially dangerous acts (SDA. It is shown that evaluation of such adolescents is generally categorical and polar, the semantic field is subdifferentiable, less hierarchic, and has not enough realistic structure of meanings. Developed structure of motives and meanings is the basis of voluntary regulation of socially significant behavior. Thus, assessing the semantic sphere of juvenile offenders we can highlight its characteristics as risk factors of unlawful behavior, as well as the resource side, that will contribute to addressing issues of prevention and correction of unlawful behavior. Key words: juvenile offenders, semantic field of juvenile offenders, unlawful behavior.

  13. A Practical Approach to Juvenile Dermatomyositis and Juvenile Scleroderma.

    2016-02-01

    Juvenile dermatomyositis and juvenile scleroderma are rare multisystem autoimmune disorders. Although they share some pathognomonic hallmarks with adult onset myositis or scleroderma, there are significant differences in presentation, characteristics and associated features when the diseases present in childhood. In view of this, and the rarity of the conditions, it is important for care to be led by teams with expertise in pediatric rheumatology conditions. Prognosis has improved significantly in the West; likely due to early diagnosis and aggressive treatment with immunosuppressive medications. However, this trend is not replicated in the developing world. Early recognition of these diseases is crucial to achieve rapid and sustained remission and prevent disease or medication associated complications. This article aims to provide a practical overview for recognition, diagnosis and treatment of these conditions.

  14. Effects of the juvenile hormone analogue methoprene on rate of behavioural development, foraging performance and navigation in honey bees (Apis mellifera).

    Science.gov (United States)

    Chang, Lun-Hsien; Barron, Andrew B; Cheng, Ken

    2015-06-01

    Worker honey bees change roles as they age as part of a hormonally regulated process of behavioural development that ends with a specialised foraging phase. The rate of behavioural development is highly plastic and responsive to changes in colony condition such that forager losses, disease or nutritional stresses accelerate behavioural development and cause an early onset of foraging in workers. It is not clear to what degree the behavioural development of workers can be accelerated without there being a cost in terms of reduced foraging performance. Here, we compared the foraging performance of bees induced to accelerate their behavioural development by treatment with the juvenile hormone analogue methoprene with that of controls that developed at a normal rate. Methoprene treatment accelerated the onset of both flight and foraging behaviour in workers, but it also reduced foraging span, the total time spent foraging and the number of completed foraging trips. Methoprene treatment did not alter performance in a short-range navigation task, however. These data indicate a limitation to the physiological plasticity of bees, and a trade off between forager performance and the speed at which bees begin foraging. Chronic stressors will be expected to reduce the mean age of the foraging force, and therefore also reduce the efficiency of the foraging force. This interaction may explain why honey bee colonies react to sustained stressors with non-linear population decline. © 2015. Published by The Company of Biologists Ltd.

    Full Text Available The purpose of this paper is to investigate how PBL student teams develop specific leadership configurations when implementing interdisciplinary projects and whether or not tutors help in dealing with the group interactions that are subsequently generated. The data set was drawn from 2 cohorts of first-year students engaged in PBL activities in an engineering school in Belgium in 2011 and 2012. Following qualitative content analysis of tutor and student feedback and the use of sociometric testing, findings for 2011 showed that students developed 4 specific leadership configurations, each of them being positively correlated to specific perceived work outcomes. Findings for 2012 were based on using the sociogram as a pedagogical tool to enable tutors to describe and regulate group dynamics. We found that tutors positively perceive their role in facilitating production outcomes but are more uncomfortable when it comes to regulating the interpersonal problems that arise in student self-managed teams.

    Full Text Available Perinatal exposure to maternal obesity and high-fat diet (HFD consumption not only poses metabolic risks to offspring but also impacts brain development and mental health. Using a non-human primate model, we observed a persistent increase in anxiety in juvenile offspring exposed to a maternal HFD. Postweaning HFD consumption also increased anxiety and independently increased stereotypic behaviors. These behavioral changes were associated with modified cortisol stress response and impairments in the development of the central serotonin synthesis, with altered tryptophan hydroxylase-2 mRNA expression in the dorsal and median raphe. Postweaning HFD consumption decreased serotonergic immunoreactivity in area 10 of the prefrontal cortex. These results suggest that perinatal exposure to HFD consumption programs development of the brain and endocrine system, leading to behavioral impairments associated with mental health and neurodevelopmental disorders. Also, an early nutritional intervention (consumption of the control diet at weaning was not sufficient to ameliorate many of the behavioral changes, such as increased anxiety, that were induced by maternal HFD consumption. Given the level of dietary fat consumption and maternal obesity in developed nations these findings have important implications for the mental health of future generations.

    1993-01-01

    We are interested in developing effective performance-oriented training for the operation of systems that are used for monitor and control purposes. We have focused on one such system, the communications Link Monitor and Control (LMC) system used in NASA's Deep Space Network (DSN), which is a worldwide system for navigating, tracking and communicating with unmanned interplanetary spacecraft. The tasks in this domain are procedural in nature and require reactive, goal-oriented skills; we have previously described a cognitive model for problem solving that accounts for both novice and expert levels of behavior as well as how skill is acquired. Our cognitive modeling work in this task domain led us to make a number of predictions about tutoring that have influenced the design of the system described in this paper.

    2016-01-01

    The aim of the present study was to investigate if the effects of the androgen, dihydrotestosterone (DHT) on the sexual development in juvenile Murray rainbowfish (Melanotaenia fluviatilis) are canceled out by the anti-androgen, flutamide. Fish (60 days post hatch) were exposed to 250ng/L of DHT, 25μg/L of flutamide (Flu-low), 250μg/L of flutamide (Flu-high), DHT+Flu low and DHT+Flu high. After 35 days of exposure, lengths and weights of the fish were measured and the condition factor (CF) calculated; vitellogenin (VTG) concentrations were measured in tail tissue; sex steroid hormones (17β-estradiol [E2] and 11-keto testosterone [11-KT]) were measured in the head tissue and abdominal regions were used in histological investigation of the gonads. Treatment with DHT reduced the body-length of both male and female fish, an effect which was canceled out by low and high concentrations of flutamide. However, flutamide (low or high) could not nullify the DHT-induced reduction in the CF in either sex. The E2 levels were reduced only in female fish after exposure to DHT but returned to normal after treatment with Flu-high. DHT increased the levels of 11-KT and decreased the E2/11-KT ratio in both sexes. Flu-high, but not Flu-low, could nullify these effects. Both DHT and flutamide (low or high) induced VTG production and this effect persisted when both chemicals were co-administered. Treatment with DHT did not affect gonadal cell development in the testes. However, the female fish treated with DHT contained ovaries in early-vitellogenic stage in comparison to the pre-vitellogenic ovaries in control fish. Co-treatment with flutamide (low or high) resulted in oocyte atresia. The results from the present study suggest that treatment with Flu-high could cancel out DHT-induced effects only on the hormonal profile and body-length in both male and female fish. Juvenile fish co-treated with DHT and flutamide (low or high) had high VTG levels and low CF. In addition, the ovaries

    To improve collaboration and the quality of care, healthcare programmes are increasingly promoting interprofessional education thereby enabling students to learn with, from and about each other. A reciprocal peer learning model has developed among pre-registration physiotherapy and adult nursing students at Plymouth University, England. Embedded within the curriculum, it provides voluntary opportunities for year two students to become cross professional peer tutors to year one students while enhancing interprofessional understanding and skills acquisition. To explore participant experiences of two cross professional peer tutored clinical skills workshops delivered to a cohort of nursing (n = 67) and physiotherapy (n = 53) students in 2015. A mixed methods approach generated qualitative and quantitative data. Qualitative data was gathered via focus groups and individual interviews of peer tutors and learners (n = 27). These were recorded, transcribed and thematically analysed. The Readiness for Interprofessional Learning Scale questionnaire (n = 84) was completed before and after the workshops to consider any influence on students' attitudes towards interprofessional learning. Four themes evolved from thematic analysis; benefits of cross professional peer tutoring, interprofessional teamwork, quality of care and factors influencing the delivery of the workshops. Data showed students felt they developed greater understanding of interprofessional roles and acquired new skills. Peer tutors developed confidence in representing their profession while appearing to inspire early stage students. The Readiness for Interprofessional Learning Scale questionnaire data identified very positive attitudes towards interprofessional learning among the majority of students in both cohorts before and after the workshop. This study endorses the utility of enhancing the Higher Education experience by offering voluntary peer tutoring opportunities. Participating students

    2004-01-01

    Seventy-three deaf college students completed a survey examining perceptions about tutoring outcomes and emphases, characteristics of tutors, and responsibilities associated with learning through tutoring. The comparisons revealed that while baccalaureate and sub-baccalaureate students have many similar perceptions about tutoring, there are also some striking differences. In particular, as compared to the sub-baccalaureate students, baccalaureate students have a stronger preference for focusing on course content and for working with tutors who actively involve them during the tutoring sessions. In addition, baccalaureate students prefer to decide the focus of the tutoring themselves while sub-baccalaureate students tend to leave the decision to the tutor. The results of the analyses with three scales measuring perceptions of tutoring dimensions are summarized and recommendations for the selection and preparation of tutors, as well as for future research, are provided.

  17. The Curtin Coaches: Benefits of an outreach tutoring program for first year pre-service teachers. A Practice Report

    Directory of Open Access Journals (Sweden)

    Saul Karnovsky

    2015-03-01

    Full Text Available The Curtin Coaches program represents a dynamic outreach opportunity for pre-service teachers enrolled in their first year of study at Curtin University to engage with school-aged students as classroom tutors. Research has shown that cross-age tutoring experiences in schools can benefit both the students receiving support and those who tutor, particularly in settings where individuals are engaging in community support work. According to program feedback, participants were able to develop a range of profession-related skills such as relationship building and gain new knowledge such as understanding how students learn. These competencies are salient as they align with the newly implemented standards for graduate teachers. Understanding the benefits such outreach programs bring pre-service teachers is vital as the future of HEPPP funded programs such as the Curtin Coaches is uncertain but the importance of Work Integrated Learning is increasing.

    The Peer Mentor Tutor (PMT) program in the University of Wisconsin-Madison's Physics Department matches upper level undergraduate physics majors in small groups with students potentially at-risk for having academic trouble with their gateway introductory non-calculus physics course or for feeling isolated at the University. The program enhances students'learning and confidence by providing an emphasis on problem solving, a supportive environment for asking questions, and opportunities for acquiring missing math skills. The students assisted include, among others, returning adults, students of color,students with English as a second language, and students who have never taken physics in high school. The tutors acquire teaching and leadership experience with ongoing training throughout the year. The Physics PMT program is run in collaboration with a similar program in Chemistry. The peer model is also being applied to other science courses at the University of Wisconsin. We will describe the structure of the Physics PMT program and our current efforts to expand the program into a broader Physics Learning Center that may serve multiple purposes and courses.

    Full Text Available Este artículo analiza los beneficios del ocio juvenil y su aportación al desarrollo personal y social con el objetivo de esclarecer si el tipo de actividad de ocio, el género, los espacios y el carácter espontáneo u organizado del ocio inciden en la percepción de beneficios emocionales, cognitivos, sociales, físicos y desarrollo de destrezas y habilidades técnicas. La muestra se compone de 1253 jóvenes españoles con edades entre los 16 y 18 años. Los resultados corroboran el influjo de estas variables tanto en la percepción de beneficios como en la naturaleza de los mismos. El ocio físico-deportivo no es solo la práctica más significativa, sino también la que les proporciona un abanico más amplio de retornos positivos. Los chicos obtienen puntuaciones más altas en todos los tipos de beneficios, excepto en los emocionales. Algunos espacios del ocio resultan más proclives para el logro de ciertos beneficios. Finalmente, el ocio organizado aporta mayores beneficios que el no organizado. La discusión sobre el rol de estas variables es clave para hacer del ocio un factor de desarrollo juvenil. | This study aims to explore the benefits of youth leisure in order to clarify whether the type of leisure activity, gender, space and organization of leisure practice affect the perception of different categories of benefits: emotional, cognitive, social physical and the acquisition of abilities and technical skills.

    The Writing Pal is an intelligent tutoring system that provides writing strategy training. A large part of its artificial intelligence resides in the natural language processing algorithms to assess essay quality and guide feedback to students. Because writing is often highly nuanced and subjective, the development of these algorithms must consider a broad array of linguistic, rhetorical, and contextual features. This study assesses the potential for computational indices to predict human ratings of essay quality. Past studies have demonstrated that linguistic indices related to lexical diversity, word frequency, and syntactic complexity are significant predictors of human judgments of essay quality but that indices of cohesion are not. The present study extends prior work by including a larger data sample and an expanded set of indices to assess new lexical, syntactic, cohesion, rhetorical, and reading ease indices. Three models were assessed. The model reported by McNamara, Crossley, and McCarthy (Written Communication 27:57-86, 2010) including three indices of lexical diversity, word frequency, and syntactic complexity accounted for only 6% of the variance in the larger data set. A regression model including the full set of indices examined in prior studies of writing predicted 38% of the variance in human scores of essay quality with 91% adjacent accuracy (i.e., within 1 point). A regression model that also included new indices related to rhetoric and cohesion predicted 44% of the variance with 94% adjacent accuracy. The new indices increased accuracy but, more importantly, afford the means to provide more meaningful feedback in the context of a writing tutoring system.

    This presentation concentrates on knowledge acquisition and its application to the development of an expert module and a user interface for an Intelligent Tutoring System (ITS). The Systems Test and Operations Language (STOL) ITS is being developed to assist NASA control center personnel in learning a command and control language as it is used in mission operations rooms. The objective of the tutor is to impart knowledge and skills that will permit the trainee to solve command and control problems in the same way that the STOL expert solves those problems. The STOL ITS will achieve this object by representing the solution space in such a way that the trainee can visualize the intermediate steps, and by having the expert module production rules parallel the STOL expert's knowledge structures.

    Full Text Available This article brings the analysis of a study—of a descriptive-analytical nature—about online tutoring, some of its characteristics and peculiarities as compared to face-to-face education. To this end it analyzes the results of an online questionnaire answered by 222 tutors pertaining to programs offered at Universidade Federal de São Carlos (UFSCar in partnership with Universidade Aberta do Brasil (UAB and Brazilian townships. The analysis focused on tutors’ characteristics (e.g., sex, education background and teaching experience, their work organization and activities, the division of labor (between tutors and teachers responsible for subjects, and their perceptions about the nature of tutoring and education at a distance (DE. This study is chiefly based on authors such as Lortie, Tardif, and Shulman—about face-to-face teaching—and Mill, Maggio, and Kenski—on distance education. The results of this study point to the predominance of female tutors, which resembles the makeup of the teaching body in face-to-face education at the lower levels, and indicate the respondents’ high levels of schooling and considerable face-to-face teaching experience. Despite the difficulties encountered by the tutors in this study, mainly due to their lack of experience in DE and varied technical problems, most of the tutors found it easy and pleasurable to work online. The dada also suggest that the tutors enjoyed comparative autonomy as regards actions associated with content transmission as well as actions related to (virtual classroom management. This autonomy may be the basis for the respondents’ perception that the online tutor, in the context under consideration, performs a genuine teaching function.

    Full Text Available Juvenile idiopathic arthritis is the most common chronic rheumatic disease of unknown aetiology in childhood and predominantly presents with peripheral arthritis. The disease is divided into several subgroups, according to demographic characteristics, clinical features, treatment modalities and disease prognosis. Systemic juvenile idiopathic arthritis, which is one of the most frequent disease subtypes, is characterized by recurrent fever and rash. Oligoarticular juvenile idiopathic arthritis, common among young female patients, is usually accompanied by anti-nuclear antibodie positivity and anterior uveitis. Seropositive polyarticular juvenile idiopathic arthritis, an analogue of adult rheumatoid arthritis, is seen in less than 10% of paediatric patients. Seronegative polyarticular juvenile idiopathic arthritis, an entity more specific for childhood, appears with widespread large- and small-joint involvement. Enthesitis-related arthritis is a separate disease subtype, characterized by enthesitis and asymmetric lower-extremity arthritis. This disease subtype represents the childhood form of adult spondyloarthropathies, with human leukocyte antigen-B27 positivity and uveitis but commonly without axial skeleton involvement. Juvenile psoriatic arthritis is characterized by a psoriatic rash, accompanied by arthritis, nail pitting and dactylitis. Disease complications can vary from growth retardation and osteoporosis secondary to treatment and disease activity, to life-threatening macrophage activation syndrome with multi-organ insufficiency. With the advent of new therapeutics over the past 15 years, there has been a marked improvement in juvenile idiopathic arthritis treatment and long-term outcome, without any sequelae. The treatment of juvenile idiopathic arthritis patients involves teamwork, including an experienced paediatric rheumatologist, an ophthalmologist, an orthopaedist, a paediatric psychiatrist and a physiotherapist.

    2009-08-01

    The rhabditid nematodes Steinernema carpocapsae and Steinernema feltiae are used in biological control of insect pests. Mass production is done in liquid culture media pre-incubated with their bacterial symbionts Xenorhabdus nematophila and Xenorhabdus bovienii, respectively, before nematode dauer juveniles (DJs) are inoculated. As a response to food signals produced by the bacterial symbionts, the DJs exit from the developmentally arrested dauer stage (they recover development) and grow to adults, which produce DJ offspring. Variable DJ recovery after inoculation often causes process failure due to non-synchronous population development and low numbers of adult nematodes. This contribution investigated the influence of the bacterial cell density on DJ recovery and development to adults. At higher density of 10(10) bacterial cells ml(-1), a higher percentage of DJ recovery was induced, and adults occurred earlier in both Steinernema spp. than at lower density of 10(9) and 10(8) cells ml(-1). Xenorhabdus symbionts produce phase variants. Recovery in bacteria-free supernatants was lower than in supernatants containing bacterial cells for both primary and secondary phase Xenorhabdus spp. and lower in secondary than in primary phase supernatants or cell suspensions. In general, recovery was lower for Steinernema feltiae and the time at which 50% of the population had recovered after exposure to the food signal was longer (RT(50) = 17.1 h) than for Steinernema carpocapsae (RT(50) = 6.6 h). Whereas >90% S. carpocapsae DJs recovered in hemolymph serum of the lepidopteran insect Galleria mellonella, recovery of S. feltiae only reached 31%. Penetration into a host insect prior to exposure to the insect's food signal did not enhance DJ recovery. Consequences for liquid culture mass production of the nematodes and differences between species of the genera Steinernema and Heterorhabditis are discussed.

    Full Text Available The semipresential modality at high school level for adults, as the offered in the nightlife high school of the Universidad Autonoma de Sinaloa, that creates high expectations for Sinaloa´s society, to give the student an opportunity to continue its educational development in high school level and, lead him to continue with their vocational training. With this investigation, and given to their conditions, the objective it´s to know the competitive level at the beginning and during the development in the institution, also to identify the influence of the school tutoring in the development of adult students in high school. It was identified the income profile of students to the institution; was necessary to rescue the results of CENEVAL and EDAOM tests, practiced at the entry of students to the institution. Together this tools, was necessary to practice two questionnaires to evaluate the students perception about their teachers; and another one to identify the main problems they faced and the function of their school tutor in the institution. With the data obtained, were identified some deficiencies of semipresential system, especially in educational planning. Even though the students recognizes that the tutoring its fundamental to the incorporation of students to academic activities and that exists a high level of acceptance to the programs set by the institution.

    Full Text Available A video-based method of instruction was introduced to develop students academically as well as to implement parallel medium instruction. An action research approach was followed Lectures were video-taped beforehand and worked through with the students by a tutor in scheduled Afrikaans or English periods. Simultaneously a live class situation was handled by the lecturer in the other language. Over and above these methods additional video-based support sessions were conducted by tutors for high risk students. A survey indicated that 85% of students were satisfied with this method of instruction. The perceptions of high risk students to VSI were positive and they passed the examinations. Video lectures need to be carefully planned in order to be acceptable as one of a number of possible instruction methods at a multi-cultural university.

    Power systems are presently remotely operated and controlled from control centers that receive on-line information about the power system state. Control center operators have very high-demanding tasks what makes their training a key issue for the performance of the whole power system. Simulators are usually used by electrical utilities for this purpose but they are very expensive applications and their use requires the preparation of the training sessions by qualified training staff which is a very time consuming task. Due to this, these simulators are only used a few times a year. Intelligent Tutoring Systems (ITS) provide some new possibilities for control center operator training making easier its use without much assistance of the teaching staff. On the other hand, an expert system in use in a control center can be adapted to an ITS to train operators without much effort. 18 refs

    2011-02-01

    Support is imperative for nursing students worldwide as they face the many challenges associated with learning and working. Moreover enhancing student retention is an increasing concern for institutions across the globe. The personal tutor is a frequently hidden yet potentially significant figure in many students' experience of higher education. This paper offers some critical reflections on a structured approach to personal tutoring within an undergraduate nursing programme in a research focused Welsh university. Structured personal tutoring can provide an organised, coherent and proactive support system throughout students' educational programmes. However the approach changes the shape of personal tutoring and has the potential to increase academics' workloads and with it costs. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Caries prevalence in underprivileged children is particularly high and, even though many efforts have been made, adherence to dental preventive programs is low. The purpose of this study was to evaluate whether a tutoring program can improve oral health behavior in underprivileged and/or immigrant children. Thirty fourth-grade children (mean age = 9.6), over 50 percent of immigrant background, participated in this longitudinal pilot study. The fourth graders were invited to develop on oral health program for their first-grade peers. For this purpose, the fourth graders learned oral health practices and developed the peer tutoring program. Prior to the intervention and after having instructed their first-grade peers, all fourth graders were interviewed about their oral health habits and their tooth-brushing was recorded on video. Toothbrushing time, performance of circular tooth-brushing movements, and systematic cleaning of all dental surfaces were analyzed before and after the intervention. After peer teaching, there was a significant increase concerning tooth-brushing time (P = .004), performance of circular tooth-brushing movements (P tutoring program yielded a significant improvement in relevant oral care behavior. This approach provided an environment which, in contrast to traditional approaches, facilitates empowerment.

    Full Text Available Background: Coaching psychology is of increasing interest to medical educators for its potential benefits as a facilitative method in problem-based learning (PBL. However, the field lacks empirical studies that explore the lived experiences of students and tutors in the PBL coaching process. This study aimed to elicit knowledge regarding medical students’ and tutors’ experiences and perceptions of PBL coaching in the context of Chinese undergraduate medical education. Methods: The qualitative methodology of interpretative phenomenological analysis (IPA was employed. Participants comprised third year medical students (n=20 and PBL tutors (n=5 who have adopted a coaching approach in PBL for a semester. Semi-structured interviews were utilized to obtain a comprehensive understanding of their experiences of PBL coaching. Data analysis followed an iterative four-stage scheme of Biggerstaff and Thompson. Results: Six main themes emerged from diverse experiences and interpretations: 1 mindsets of coaching and learning, 2 the development of learning dispositions and capacities, 3 student group collaboration, 4 tutor–student relationships, 5 personal and professional development, and 6 challenges and difficulties in implementation. Conclusions: It could be concluded that PBL coaching is a dynamic, facilitative process that makes a particular contribution to the learning process from psychological, emotional, and social perspectives, whilst it demonstrates significant overlaps with PBL tutoring in terms of supporting students’ cognitive activities in PBL. Further research is needed to identify the barriers and challenges for medical educators to implement coaching in the PBL process.

    Abstract Background: Juvenile polyposis syndrome, a rare disorder in children, is characterized with multiple hamartomatous polyps in alimentary tract. A variety of manifestations include bleeding, intussusception, or polyp prolapse. In this study, we present an 8-month-old male infant of juvenile polyposis syndrome initially presenting with chronic anemia. To the best of our knowledge, this is the youngest case reported in the literature. Methods: We report a rare case of an 8-month-old male infant who presented with chronic anemia and gastrointestinal bleeding initially. Panendoscopy and abdominal computed tomography showed multiple polyposis throughout the entire alimentary tract leading to intussusception. Technetium-99m-labeled red blood cell (RBC) bleeding scan revealed the possibility of gastrointestinal tract bleeding in the jejunum. Histopathological examination on biopsy samples showed Peutz-Jeghers syndrome was excluded, whereas the diagnosis of juvenile polyposis syndrome was established. Results: Enteroscopic polypectomy is the mainstay of the treatment. However, polyps recurred and occupied the majority of the gastrointestinal tract in 6 months. Supportive management was given. The patient expired for severe sepsis at the age of 18 months. Conclusion: Juvenile polyposis syndrome is an inherited disease, so it is not possible to prevent it. Concerning of its poor outcome and high mortality rate, it is important that we should increase awareness and education of the parents at its earliest stages. PMID:27631205

    Victims of child abuse and neglect are at an increased risk of involvement with the juvenile justice and adult correctional systems. Yet, little is known about the continuation and trajectories of offending beyond initial contact with law enforcement. Neglect likely plays a critical role in continued offending as parental monitoring, parental rejection and family relationships are instrumental in explaining juvenile conduct problems. This study sought to determine whether neglect is associated with recidivism for moderate and high risk juvenile offenders in Washington State. Statewide risk assessments and administrative records for child welfare, juvenile justice, and adult corrections were analyzed. The sample was diverse (24 % female, 13 % African American, 8 % Hispanic, 5 % Native American) and included all moderate and high risk juvenile offenders screened by juvenile probation between 2004 and 2007 (n = 19,833). Official records from child protection were used to identify juvenile offenders with a history of child neglect and to identify juvenile offenders with an ongoing case of neglect. Event history models were developed to estimate the risk of subsequent offending. Adolescents with an ongoing case neglect were significantly more likely to continue offending as compared with youth with no official history of neglect. These findings remain even after controlling for a wide range of family, peer, academic, mental health, and substance abuse covariates. Interrupting trajectories of offending is a primary focus of juvenile justice. The findings of the current study indicate that ongoing dependency issues play a critical role in explaining the outcomes achieved for adolescents in juvenile justice settings. The implications for improved collaboration between child welfare and juvenile justice are discussed.

    A 14-year-old boy presented with months of severe widespread musculoskeletal pain. He was profoundly fatigued and unable to attend school. Laboratory evaluation, including complete blood count, comprehensive metabolic panel, inflammatory markers, and thyroid function, was unrevealing. Physical examination was also normal except for multiple tender points. The patient was diagnosed with juvenile primary fibromyalgia syndrome and referred for multidisciplinary treatment including physical therapy, exercise, and counseling, and his daily functioning gradually improves. Juvenile fibromyalgia is a complex syndrome that often severely limits patients' activities and can impede normal adolescent development. Effective treatment requires an understanding of the biologic, psychologic, and social factors contributing to the perpetuation of chronic pain. The author reviews the diagnostic criteria, pathophysiology, and treatment of juvenile fibromyalgia. Medications, particularly antidepressants and anticonvulsants, can be useful adjuncts to therapy. However, multimodal pain management including intensive physical therapy, exercise, counseling, and sleep hygiene is most effective in treating fibromyalgia. Copyright 2015, SLACK Incorporated.

    The effects of sublethal concentrations of tributyltin (TBT) on growth of juvenile clams Ruditapes decussatus were determined during exposure to TBT concentrations of 50, 100 and 250 ng l(-1) (as Sn) for a period up to two years. Length and weight of clams increased continuously in all treatments throughout the experimental period, and, overall, rates were not significantly influenced by TBT exposure, although final length and weight were inversely related to increasing TBT concentration. Juvenile R. decussatus therefore appear to be less sensitive to TBT than larval stages. Some juveniles exposed to TBT developed abnormal shell growth, laterally, changing the typical flattened shape of clams into a more "rounded" form. This characteristic was more visible in the anterior margins of valves than posteriorly, and mainly observed in clams exposed to TBT at 50 ng l(-1) (as Sn).

  13. An integrated 2-year clinical skills peer tutoring scheme in a UK-based medical school: perceptions of tutees and peer tutors

    2018-01-01

    Background Several benefits of peer tutoring in medical school teaching have been described. However, there is a lack of research on the perceptions of peer tutoring, particularly from tutees who partake in a long-term clinical skills scheme integrated into the medical school curriculum. This study evaluates the opinions of preclinical tutees at the end of a 2-year peer-tutored clinical skills program and peer tutors themselves. Methods A cross-sectional study was conducted in a UK-based medical school that primarily utilizes peer tutoring for clinical skills teaching. A questionnaire was designed to assess the views of preclinical tutees and peer tutors. Likert scales were used to grade responses and comment boxes to collect qualitative data. Results Sixty-five questionnaires were collected (52 tutees, 13 peer tutors). Seventy-nine percent of students felt satisfied with their teaching, and 70% felt adequately prepared for clinical placements. Furthermore, 79% believed that peer tutoring is the most effective method for clinical skills teaching. When compared to faculty teaching, tutees preferred being taught by peer tutors (63%), felt more confident (73%), and were more willing to engage (77%). All peer tutors felt that teaching made them more confident in their Objective Structured Clinical Examination performance, and 91% agreed that being a tutor made them consider pursuing teaching in the future. Thematic analysis of qualitative data identified 3 themes regarding peer tutoring: a more comfortable environment (69%), a more personalized teaching approach (34%), and variation in content taught (14%). Conclusion Preclinical tutees prefer being taught clinical skills by peer tutors compared to faculty, with the peer tutors also benefitting. Studies such as this, looking at long-term schemes, further validate peer tutoring and may encourage more medical schools to adopt this method as an effective way of clinical skills teaching.

    Juvenile idiopathic arthritis (JIA) is a common autoimmune disease characterized by environmental influences along with several predisposing genes in the pathogenesis. The protein tyrosine phosphatase nonreceptor 22 (PTPN22) and signal transducer and activator of transcription factor 4 (STAT4) have been recognized as susceptibility genes for numerous autoimmune diseases. Associations of STAT4 rs7574865 G/T and PTPN22 (rs2488457 G/C and rs2476601 C/T) polymorphisms with JIA have repeatedly been replicated in several Caucasian populations. The aim of this study was to investigate the influence of three polymorphisms mentioned above on the risk of developing JIA in Han Chinese patients. Genotyping was performed on a total of 137 Chinese patients with JIA (JIA group) and 150 sex and age frequency-matched healthy volunteers (Control group). The single-nucleotide polymorphisms (SNP) were determined by using direct sequencing of PCR-amplified products. There were significant differences of PTPN22 rs2488457 G/C and STAT4 rs7574865 G/T polymorphisms between both groups. However, no significant difference was observed in distribution frequencies of PTPN22 rs2476601 polymorphism. The association with the PTPN22 rs2488457 G/C polymorphism remained significant in the stratifications by age at onset, ANA status, splenomegaly, lymphadenectasis and involvement joints. As with the STAT4 rs7574865 G/T polymorphisms, the enthesitis-related arthritis and presence of hepatomegaly had strong effect on the association. Our data strengthen STAT4 rs7574865 G/T and PTPN22 rs2488457 G/C polymorphisms as susceptibility factors for JIA.

    2017-04-01

    The aim of this work is to present some experiences of intergenerational education about meteorology and climatology issues carried out with school pupils from 6 to 19 years old, through peer-tutoring methodology. These experiences started in 2003 and each year the project involves about 500 students in Friuli Venezia Giulia region (about 8.000 km2) in northeastern Italy. A group of volunteers (older students from upper secondary school, 17-19 years old) play the role of "tutor": they receive supplementary training on meteorology and climatology, and then, during students' meetings and/or public events, they teach younger pupils how to use meteorological instruments (thermometer, hygrometer, barometer, anemometer, rain gages, etc.) and they carry out interactive experiences such as "game-experiments", to better understand some meteorological concepts, like density of fluids, and some climatological notions, like the effects of climate change with an exhibit that simulates the greenhouse effect. They also do some meteorological forecasting exercises, using meteorological maps, as if they were actual forecasters. All these activities are addressed to pupils from primary (age 6-11) and lower secondary schools (age 11-14), and both tutors and their younger "apprentices" are not only cognitively, but also emotionally involved in such learning experiences. As a second step of this educational process, after consolidating the above mentioned peer-tutoring activities, high school students hare being actively involved in developing visual tools - e.g. video-clips, interviews and cartoons - in order to communicate climate change issues in the most effective way to younger pupils. Keywords: meteorology, climatology, climate change, schools, education, communication.

    2014-11-01

    Full Text Available When creating computer-assisted language learning software, it is necessary to use the potential of information technology in controlling the learning process fully. Modern intelligent tutoring systems help to make this process adaptive and personalized thanks to modeling the domain and students’ knowledge. The aim of the paper is to investigate possibilities for applying these methods in teaching Polish grammar in Ukraine taking into account its specifics. The article is concerned with the approaches of using student models in modern intelligent tutoring systems in order to provide personalized learning. A structure of the student model and a general working algorithm of the expert tutoring system of Polish grammar have been developed. The modeling of knowing and forgetting particular learning elements within the probabilistic (stochastic model has been studied, as well as the prognostication of future probabilities of students’ knowledge, taking into account their individual forgetting rates. The objective function of instruction quality with allowance for frequency of grammar rules within a certain amount of words being learned and their connections to another rules has been formulated. The problem of generating the next learning step taking into account the need for mastering previous, connected rules has been studied, as well as determining the optimal time period between the lessons depending on the current knowledge level.

Outreach methods included peer tutor selection, train-the-trainer sessions, school and community outreach, and pre- and posttests of MedlinePlus training sessions. Evaluation methods included Web statistics; end-of-project interviews; focus groups with students, faculty, and librarians; and end-of-project surveys of students and faculty. Results: Four peer tutors reached more than 2,000 people during the project year. Students and faculty found MedlinePlus to be a useful resource. Faculty and librarians developed new or revised teaching methods incorporating MedlinePlus. The project enhanced the role of school librarians as agents of change at Med High. The project continues on a self-sustaining basis. Conclusions: Using peer tutors is an effective way to educate high school students about health information resources and, through the students, to reach families and community members.

    A 23-year-old woman who had an operation and chemo-radiation therapy for a neuroblastoma of the left adrenal gland at the age of five months developed a fever and left hypochondralgia when she was 22 years old. A splenic abscess was noted. Percutaneous drainage was done, but the splenic abscess recurred. There was no recurrence of the neuroblastoma. Conservative therapy was unsuccessful and a laparotomy was performed. Operative findings included a bulky mass at the splenic flexure which involved the spleen, pancreas tail, and jejunum. Colectomy at the splenic flexure was performed with coresection of the spleen, pancreas tail, and jejunum. The surgical specimen showed mucinous carcinoma of the splenic flexure which invaded the spleen. This case was considered to be an radiation-induced secondary colon cancer. (author)

  3. Essential habitat for sardine juveniles in Iberian waters

    Full Text Available In a period when the Iberian sardine stock abundance is at its historical minimum, knowledge of the sardine juvenile’s distribution is crucial for the development of fishery management strategies. Generalized additive models were used to relate juvenile sardine presence with geographical variables and spawning grounds (egg abundance and to model juvenile abundance with the concurrent environmental conditions. Three core areas of juvenile distribution were identified: the Northern Portuguese shelf (centred off Aveiro, the coastal region in the vicinity of the Tagus estuary, and the eastern Gulf of Cadiz. Spatial differences in the relationship between juvenile presence and egg abundances suggest that essential juvenile habitat might partially differ from the prevailing spawning grounds. Models also depicted significant relationships between juvenile abundance, temperature and geographical variables in combination with salinity in the west and with zooplankton in the south. Results indicate that the sardine juvenile distribution along the Iberian Peninsula waters are an outcome of a combination of dynamic processes occurring early in life, such as egg and larva retention, reduced mortality and favourable feeding grounds for both larvae and juveniles.

    Full Text Available Atherosclerosis is a chronic inflammatory disease of the arteries. Clinical consequences of the atherosclerotic process occur in the adult population, however atherosclerotic process begins in childhood. The classic risk factors for atherosclerosis include obesity, dyslipidaemia, age, gender or family history. In recent years, attention has been drawn to the similarity between atherosclerotic inflammatory processes and inflammatory changes in the course of systemic connective tissue disease, in particular systemic lupus etythematosus (SLE or rheumatoid arthritis (RA. There is also observed the similarity of the pathogenetic background of development of atherosclerosis and juvenile idiopathic arthritis (JIA. Elevated levels of pro-inflammatory cytokines are observed in the course of juvenile idiopathic arthritis. Also homocysteine concentrations, which may play a significant role in the development of atherosclerotic lesions, are observed higher in patients with JIA. Some studies revealed higher carotid intima-media thickness (IMT index values in children with JIA. In view of the fact that atherosclerotic process begins as early as in childhood, the introduction of appropriate preventive measures in children is a matter of utmost importance.

    Full Text Available The purpose of virtual education or e-Learning is to promote the development of independent study. In this environment the virtual tutor is a guide for the student learning alone and without the presence of the teacher. Training for tutors is a challenging experience that requires interest, discipline, responsibility, research and application of knowledge, cognitive readjustment, intrinsic and extrinsic motivation, and which generates waves of satisfaction. Therefore it is an Innovative Learning Model and a starting point for generating knowledge.This paper discloses the wonderful learning experience of spending twelve weeks on the Educational Portal of the Americas to train as a virtual tutor supported by the contents of the course: Quality Basic Education for the implementation of practices and simulations. The projection of the training course as a tutor trainee contemplates three ideas central to the appropriation of the philosophy of educational quality. Benefits provided to the academic development of participants in this process of training are reflexively interacting with professionals from various disciplines and various other Latin American contexts, and concludes with an evaluation of the course, generating interlearning e-Learning environments.

    Dyslipidemias are occurring earlier in the population due to the increase of obesity and bad eating habits. Rosuvastatin inhibits the enzyme HMG-CoA reductase, decreasing total cholesterol. Ascorbic acid is an important antioxidant compound for male reproductive system. This study aimed to evaluate whether ascorbic acid supplementation may prevent the reproductive damage provoked by rosuvastatin administration at prepuberty. Male pups were distributed into six experimental groups that received saline solution 0.9%, 3 or 10mg/kg/day of rosuvastatin, 150mg/day of ascorbic acid, or 150mg/day of ascorbic acid associated with 3 or 10mg/kg/day of rosuvastatin from post-natal day (PND) 23 until PND53. Rosuvastatin-treated groups showed delayed puberty installation, androgen depletion and impairment on testicular and epididymal morphology. Ascorbic acid partially prevented these reproductive damages. In conclusion, rosuvastatin exposure is a probable risk to reproductive development and ascorbic acid supplementation may be useful to prevent the reproductive impairment of rosuvastatin exposure.

    2007-07-01

    To develop a scale to assess satisfaction with transitional health care among adolescents with a chronic illness and their parents. The 'Mind the Gap' scale was developed using evidence from a previous needs assessment, in three stages: (1) definition of the construct; (2) design of the scale items, response options and instructions; (3) full administration of the scale, item analysis and dimensionality analysis. The scale was administered to 308 adolescents with juvenile idiopathic arthritis (JIA) and 303 parents/guardians, prior to and 12 months after the implementation of an evaluation of a structured and co-ordinated programme of transitional care. The patient population involved adolescents with JIA and their parents recruited from 10 major UK rheumatology centres. A total of 301 (97.7%) adolescents and 286 (95.0%) parents chose to complete the questionnaire, with median item completion rates of 100.0% (0-100%) for both adolescents and parents thus confirming feasibility. Face and content validity were confirmed. Factor analyses revealed a three-factor structure which explained 49.5% and 56.1% of the variation in adolescent and parent scores respectively. The internal consistency of each subscale ('management of environment', 'provider characteristics' and 'process issues') was indicated by Cronbach's alphas of 0.71, 0.89 and 0.89 for adolescents, respectively, and 0.83, 0.91 and 0.92 for parents respectively. Cronbach's alphas for the entire scales were 0.91 and 0.94 for the adolescent and parent forms respectively. These preliminary results report the potential of the 'Mind the Gap' scale in evaluating transitional care for adolescents with JIA. In view of the generic nature of transitional care reflected in the scale, this scale has wider potential for use with adolescents with other chronic illness in view of the generic nature of transition. This development is particularly timely in the context of transitional care developments in the UK and further

It was designed as quasi-experimental research with three independent groups for comparison. The Learning Styles Inventory and Motivational Orientation (Edaom questionnaire developed by Castañeda and Ortega (2004 was applied as a pre and post-test instrument subsequent to intervention with the model during a period of one semester. The results reasonably show intervention by the tutor helped to improve the students' performance compared to the other two groups and that learning through the use of instructional materials requires training on the part of the tutor.

    Full Text Available This article aims to problematize discourses about protection and care that have surrounded compulsory hospitalization by evidencing its use as a control and punishment mechanism that increases the social vulnerability of young drug users. For such, we analyze lawsuits involving juveniles who were consigned to psychiatric institutions for drug addiction treatment as a protection measure in the state of Rio Grande do Sul, in Brazil. The analysis of the materials has evidenced discourses that have circumscribed young drug users and constructed this population as potentially dangerous subjects as well as a population category at risk. In this sense, we point out how compulsory hospitalization has emerged out of the lawsuits as a tool for prevention of juvenile delinquency.

  18. Rose garden promises of intelligent tutoring systems: Blossom or thorn

    Science.gov (United States)

    Shute, Valerie J.

    1991-01-01

    Intelligent tutoring systems (ITS) have been in existence for over a decade. However, few controlled evaluation studies have been conducted comparing the effectiveness of these systems to more traditional instruction methods. Two main promises of ITSs are examined: (1) Engender more effective and efficient learning in relation to traditional formats; and (2) Reduce the range of learning outcome measures where a majority of individuals are elevated to high performance levels. Bloom (1984) has referred to these as the two sigma problem; to achieve two standard deviation improvements with tutoring over traditional instruction methods. Four ITSs are discussed in relation to the two promises. These tutors have undergone systematic, controlled evaluations: (1) The LISP tutor (Anderson Farrell and Sauers, 1984); (2) Smithtown (Shute and Glaser, in press); (3) Sherlock (Lesgold, Lajoie, Bunzo and Eggan, 1990); and (4) The Pascal ITS (Bonar, Cunningham, Beatty and Well, 1988). Results show that these four tutors do accelerate learning with no degradation in final outcome. Suggestions for improvements to the design and evaluation of ITSs are discussed.

  19. Does private tutoring increase students' academic performance? Evidence from Turkey

    Berberoğlu, Giray; Tansel, Aysit

    2014-10-01

    This paper investigates the effectiveness of private tutoring in Turkey. The authors introduce their study by providing some background information on the two major national examinations and three different kinds of tutoring. They then describe how they aimed to analyse whether attending private tutoring centres (PTCs) enhances Turkish students' academic performance. By way of multiple linear regression analysis, their study sought to evaluate whether the impact of private tutoring varies in different subject areas, taking into account several student-related characteristics such as family and academic backgrounds as well as interest in and perception of academic success. In terms of subject areas, the results indicate that while private tutoring does have a positive impact on academic performance in mathematics and Turkish language, this is not the case in natural sciences. However, as evidenced by the effect sizes, these impacts are rather small compared to the impacts of other variables such as interest in and perception of academic success, high school graduation fields of study, high school cumulative grade point average (CGPA), parental education and students' sociocultural background. While the authors point out that more research on the impact of further important variables needs to be done, their view is that school seems to be an important factor for determining students' academic performance.

  20. Development of a new method for the determination of residues of the neonictinoid insecticide imidacloprid in juvenile Chinook (Oncorhynchus tyshawytscha) using ELISA detection

    Science.gov (United States)

    Frew, John A.; Grue, Christian E.

    2012-01-01

    The neonicotinoid insecticide imidacloprid (IMI) has been proposed as an alternative to carbaryl for controlling indigenous burrowing shrimp on commercial oyster beds in Willapa Bay and Grays Harbor, Washington. A focus of concern over the use of this insecticide in an aquatic environment is the potential for adverse effects from exposure to non-target species residing in the Bay, such as juvenile Chinook (Oncorhynchus tshawytscha) and cutthroat trout (O. clarki). Federal registration and State permiting approval for the use of IMI will require confirmation that the compound does not adversely impact these salmonids following field applications. This will necessitate an environmental monitoring program for evaluating exposure in salmonids following the treatment of beds. Quantification of IMI residues in tissue can be used for determining salmonid exposure to the insecticide. Refinement of an existing protocol using liquid-chromatography mass spectrometry (LC-MS) detection would provide the low limits of quantification, given the relatively small tissue sample sizes, necessary for determining exposure in individual fish. Such an approach would not be viable for the environmental monitoring effort in Willapa Bay and Grays Harbor due to the high costs associated with running multiple analyses, however. A new sample preparation protocol was developed for use with a commercially available enzyme-linked immunosorbent assay (ELISA) for the quantification of IMI, thereby providing a low-cost alternative to LC-MS for environmental monitoring in Willapa Bay and Grays Harbor. Extraction of the analyte from the salmonid brain tissue was achieved by Dounce homogenization in 4.0 mL of 20.0 mM Triton X-100, followed by a 6 h incubation at 50–55 °C. Centrifugal ultrafiltration and reversed phase solid phase extraction were used for sample cleanup. The limit of quantification for an average 77.0 mg whole brain sample was calculated at 18.2 μg kg-1 (ppb) with an average

    2016-01-01

    Recruitment of tutors to work in problem-based learning (PBL) programs is challenging, especially in that most of them are graduated from discipline-based programs. Therefore, this study aims at examining whether lecturing skills of faculty could predict their PBL tutoring skills. This study included evaluation of faculty (n=69) who participated in both tutoring and lecturing within particular PBL units at the College of Medicine and Medical Sciences (CMMS), Arabian Gulf University, Bahrain. Each faculty was evaluated by medical students (n=45±8 for lecturing and 8±2 for PBL tutoring) using structured evaluation forms based on a Likert-type scale (poor to excellent). The prediction of tutoring skills using lecturing skills was statistically analyzed using stepwise linear regression. Among the parameters used to judge lecturing skills, the most important predictor for tutoring skills was subject matter mastery in the lecture by explaining difficult concepts and responding effectively to students' questions. Subject matter mastery in the lecture positively predicted five tutoring skills and accounted for 25% of the variance in overall effectiveness of the PBL tutors (F=22.39, P=0.000). Other important predictors for tutoring skills were providing a relaxed class atmosphere and effective use of audiovisual aids in the lecture. Predicting the tutoring skills based on lecturing skills could have implications for recruiting tutors in PBL medical programs and for tutor training initiatives.

    Chi, Michelene T H; Roy, Marguerite; Hausmann, Robert G M

    2008-03-01

    The goals of this study are to evaluate a relatively novel learning environment, as well as to seek greater understanding of why human tutoring is so effective. This alternative learning environment consists of pairs of students collaboratively observing a videotape of another student being tutored. Comparing this collaboratively observing environment to four other instructional methods-one-on-one human tutoring, observing tutoring individually, collaborating without observing, and studying alone-the results showed that students learned to solve physics problems just as effectively from observing tutoring collaboratively as the tutees who were being tutored individually. We explain the effectiveness of this learning environment by postulating that such a situation encourages learners to become active and constructive observers through interactions with a peer. In essence, collaboratively observing combines the benefit of tutoring with the benefit of collaborating. The learning outcomes of the tutees and the collaborative observers, along with the tutoring dialogues, were used to further evaluate three hypotheses explaining why human tutoring is an effective learning method. Detailed analyses of the protocols at several grain sizes suggest that tutoring is effective when tutees are independently or jointly constructing knowledge: with the tutor, but not when the tutor independently conveys knowledge. 2008 Cognitive Science Society, Inc.

    Practice tutors' evaluation to (i) establish current physical activity and exercise promotion and prescription curriculum content and (ii) their knowledge, attitudes and beliefs concerning physical activity and exercise prescription in clinical education, in terms of contemporary and emerging health trends and priorities. A cross sectional survey employing a questionnaire and focus groups. All practice tutors delivering physiotherapy undergraduate education in four physiotherapy schools in Ireland (n=38) were invited to participate. Thirty participated giving a response rate of 79%. Two methods of data collection were employed. Clinical content questionnaires were administered, the results of which informed follow-up focus groups. Focus group transcriptions were analysed using the 'Framework Analysis' method. 66% of practice tutors were unhappy with their own knowledge and felt they required further training in the following areas: strategies for changing physical activity behaviour; exercise promotion and prescription for public health; exercise prescription for lifestyle related disease. Main themes emerging from the focus groups were (i) perceptions of the physiotherapist's role, (ii) perceptions of the practice tutor's role and (iii) facilitators and barriers to change. In terms of physical activity and exercise prescription education, practice tutors identified a need for further education to improve their knowledge base. However, their attitudes and beliefs relating to physiotherapists' and educators' role in terms of teaching contemporary and emerging health trends and priorities were mixed. Results of this study provide useful data to inform future physiotherapy curricula development in terms of physical activity and exercise content. Copyright © 2011 Chartered Society of Physiotherapy.

    There are many problems with teaching and assessing impaired students in higher education, especially in technical science, where the knowledge is represented mostly by structural information like: math formulae, charts, graphs, etc. Developing e-learning platform for distance education solves this problem only partially due to the lack of accessibility for the blind. The proposed method is based on the decomposition of the typical mathematical exercise into a sequence of elementary sub-exercises. This allows for interactive resolving of math exercises and assessment of the correctness of exercise solutions at every stage. The presented methods were prepared and evaluated by visually impaired people and students. The article presents the accessible interactive tutoring platform for math teaching and assessment, and experience in exploring it. The results of conducted research confirm good understanding of math formulae described according to elaborated rules. Regardless of the level of complexity of the math formulae the level of math formulae understanding is higher for alternative structural description. The proposed solution enables alternative descriptions of math formulae. Based on the research results, the tool for computer-aided interactive learning of mathematics adapted to the needs of the blind has been designed, implemented and deployed as a platform for on-site and online and distance learning. The designed solution can be very helpful in overcoming many barriers that occur while teaching impaired students. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2013-06-01

    Full Text Available This paper describes the interactive tutoring feedback model (ITF-model; Narciss, 2006; 2008, and how it can be applied to the design and evaluation of feedback strategies for digital learning environments. The ITF-model conceptualizes formative tutoring feedback as a multidimensional instructional activity that aims at contributing to the regulation of a learning process in order to help learners acquire or improve the competencies needed to master learning tasks. It integrates findings from systems theory with recommendations of prior research on interactive instruction and elaborated feedback, on task analyses, on error analyses, and on tutoring techniques. Based on this multi-dimensional view of formative tutoring feedback methodological implications for designing and investigating multiple effects of feedback under multiple individual and situational conditions are described. Furthermore, the paper outlines how the implications of the ITF-model have been applied in several studies to the design and evaluation of tutoring feedback strategies for digital learning environments (e.g., Narciss, 2004; Narciss & Huth, 2006; Narciss, Schnaubert, Andres, Eichelmann, Goguadze, & Sosnovsky, 2013.

    Full Text Available Fibromyalgia syndrome (FM belongs to soft tissue pain syndromes of unknown cause, also referred to as “soft tissue rheumatism”. It is characterized by chronic widespread pain as well as additional symptoms such as fatigue, sleep and mood disturbance and cognitive problems. There is more and more data showing that this condition may start at a young age or even in childhood, adversely affecting development processes and resulting in dysfunctional social and family relationships. Because of the multifaceted character of fibromyalgia the efficient treatment of this disorder can be difficult and requires comprehensive care. This work reviews most recommended procedures used in integrated treatment programmes for juvenile fibromyalgia syndrome (JFM.

    Control of disease activity and recovery of function are major issues in the treatment of children and adolescents suffering from juvenile idiopathic arthritis (JIA). Functional therapies including physiotherapy are important components in the multidisciplinary teamwork and each phase of the disease requires different strategies. While in the active phase of the disease pain alleviation is the main focus, the inactive phase requires strategies for improving motility and function. During remission the aim is to regain general fitness by sports activities. These phase adapted strategies must be individually designed and usually require a combination of different measures including physiotherapy, occupational therapy, massage as well as other physical procedures and sport therapy. There are only few controlled studies investigating the effectiveness of physical therapies in JIA and many strategies are derived from long-standing experience. New results from physiology and sport sciences have contributed to the development in recent years. This report summarizes the basics and main strategies of physical therapy in JIA.

    Full Text Available Juvenile dermatomyositis has variable clinical presentations both in and outside of pregnancy. A literature review indicated that optimal maternal and fetal outcomes can be anticipated when the pregnancy is undertaken while the disease is in remission. Poorer outcomes are associated with flare-up of the disease in early pregnancy compared with exacerbation in the second or third trimester, when fetal prognosis is usually good. We present a case of JDM in pregnancy with disease exacerbation late in pregnancy and review of the relevant literature.

    An intelligent tutoring system (ITS) is proposed for a power plant simulator. With a well designed ITS, the need for an instructor is minimized and the operator may readily and efficiently take, in real-time, the control of simulator with appropriate messages he(she) gets from the tutoring system. Using SIMULINK and based on object oriented programming (OOP) and C programming language, a fossil-fuelled power plant simulator with an ITS is proposed. Promising results are demonstrated for a typical power plant.

    Tutoring centres are common in universities in the United States, but there are few published studies that statistically examine the effects of tutoring on student success. This study utilizes multiple regression analysis to model the effect of tutoring attendance on final course grades in Calculus I. Our model predicted that every three visits to the tutoring centre is correlated with an increase of a students' course grade by one per cent, after controlling for prior academic ability. We also found that for lower-achieving students, attending tutoring had a greater impact on final grades.

    Cadmium (Cd) is a major environmental contaminant. Although immunotoxic effects have been associated with Cd exposure, the inconsistency of experimental results underlines the need of an experimental approach more closely related to environmental conditions. We investigated the effects of exposing neonatal Sprague-Dawley rats to environmentally relevant doses of Cd through maternal milk. Dams received 10 parts per billion (ppb) or 5 parts per million (ppm) Cd chloride (CdCl 2 ) in drinking water from parturition until the weaning of the pups. Half of the offspring was sampled at weaning time. The remaining juvenile rats received water without addition of Cd until adulthood. Cd accumulation in kidneys of juvenile rats fed from dams exposed to Cd indicated the transfer of the metal from mother to pups through maternal milk. This neonatal exposure resulted in decreased body, kidney and spleen weights of just weaned females but not of males. This effect was more pronounced in the less exposed females fed from dams exposed to 10 ppb Cd, which also displayed lower hepatic metallothionein-1 (MT-1) mRNA levels. The effect of Cd exposure on body and organ weights did not persist to adulthood. In contrast, we observed gender-specific effects of neonatal Cd exposure on the cytotoxic activity of splenic NK-cells of both juvenile and adult rats. Cd also strongly inhibited the proliferative response of Con A-stimulated thymocytes in both male and female adult rats 5 weeks after the cessation of Cd exposure. These immunotoxic effects were observed at doses much lower than those reported to produce similar effects when exposure occurred during adulthood. In conclusion, neonatal exposures to environmentally relevant levels of Cd through maternal milk represent a critical hazard liable to lead to both transitory and persistent immunotoxic effects

    Role modelling by clinicians assists in development of medical students' professional competencies, values and attitudes. Three core characteristics of a positive role model include 1) clinical attributes, 2) teaching skills, and 3) personal qualities. This study was designed to explore medical students' perceptions of their bedside clinical tutors as role models during the first year of a medical program. The study was conducted with one cohort (n = 301) of students who had completed Year 1 of the Sydney Medical Program in 2013. A total of nine focus groups (n = 59) were conducted with medical students following completion of Year 1. Data were transcribed verbatim. Thematic analysis was used to code and categorise data into themes. Students identified both positive and negative characteristics and behaviour displayed by their clinical tutors. Characteristics and behaviour that students would like to emulate as medical practitioners in the future included: 1) Clinical attributes: a good knowledge base; articulate history taking skills; the ability to explain and demonstrate skills at the appropriate level for students; and empathy, respect and genuine compassion for patients. 2) Teaching skills: development of a rapport with students; provision of time towards the growth of students academically and professionally; provision of a positive learning environment; an understanding of the student curriculum and assessment requirements; immediate and useful feedback; and provision of patient interaction. 3) Personal qualities: respectful interprofessional staff interactions; preparedness for tutorials; demonstration of a passion for teaching; and demonstration of a passion for their career choice. Excellence in role modelling entails demonstration of excellent clinical care, teaching skills and personal characteristics. Our findings reinforce the important function of clinical bedside tutors as role models, which has implications for faculty development and

    This study examined the role of contextual factors, such as assignment rationale, on the attitudinal effects of peer tutoring. Fourth-grade children engaged in brief tutoring experiences as either a tutor or tutee. Subjects received four rationales for being selected as tutor or tutee: (a) a competence rationale, (b) a physical characteristic rationale, (c) a chance rationale, or (d) no rationale. As predicted, tutors had more positive attitudes than tutees when they had been given a competence or physical characteristic rationale but not when the tutors were provided a chance rationale or no rationale. Additionally, the tutors’ and tutees’ attitudes were enhanced when no rationale was provided. Results are discussed in terms of their implications for a role-theory analysis of tutoring and their implications for applied programs. PMID:23946549

METHOD: Randomized controlled trial. The sample consisted of 35 undergraduate nursing students, who were divided into two groups after attending an open dialogue presentation class and watching a video. One group undertook the procedure practice with a tutor and the other with the assistance of a self-learning tutorial. RESULTS: in relation to cognitive knowledge, the two groups had lower performance in the pre-test than in the post-test. The group that received assistance from a tutor performed better in the practical assessment. CONCLUSION: the simulation undertaken with the assistance of a tutor showed to be the most effective learning strategy when compared to the simulation using a self-learning tutorial. Advances in nursing simulation technology are of upmost importance and the role of the tutor in the learning process should be highlighted, taking into consideration the role this professional plays in knowledge acquisition and in the development of critical-reflexive thoughts and attitudes.

  18. Dependent vs. independent juvenile survival: contrasting drivers of variation and the buffering effect of parental care.

    2013-07-01

    Juvenile survival is often found to be more sensitive than adult survival to variation in environmental conditions, and variation in juvenile survival can have significant impacts on population growth rates and viability. Therefore, understanding the population-level effects of environmental changes requires understanding the effects on juvenile survival. We hypothesized that parental care will buffer the survival of dependent juveniles from variation in environmental conditions, while the survival of independent juveniles will respond more strongly to environmental variation and, in turn, drive the overall variation in annual juvenile survival. We tested this parental-care hypothesis using a 30-year mark-recapture data set to model the survival of juvenile Song Sparrows (Melospiza melodia) during the dependent and independent stages. We examined the effects of weather, density, and cohort mean fledge date and body mass on annual variation in survival during the first 12 weeks after fledging, as well as effects of individual fledge date and body mass on individual variation in survival. The primary driver of annual variation in juvenile survival was precipitation during the previous rainy season, consistent with an effect on food availability, which had a strong positive effect on the survival of independent juveniles, but no effect on dependent juveniles. We also found strong support for effects of body mass and fledge date on individual survival probability, including striking differences in the effect of fledge date by stage. Our results provided evidence that different mechanisms influence juvenile survival during each stage of fledgling development, and that parental care buffers the survival of dependent juveniles from variation in environmental conditions. Consequently, variation in juvenile survival was driven by independent juveniles, not dependent juveniles, and studies focused only on survival during the dependent stage may not be able to detect the

Therefore, this study aims at examining whether lecturing skills of faculty could predict their PBL tutoring skills. Methods: This study included evaluation of faculty (n=69 who participated in both tutoring and lecturing within particular PBL units at the College of Medicine and Medical Sciences (CMMS, Arabian Gulf University, Bahrain. Each faculty was evaluated by medical students (n=45±8 for lecturing and 8±2 for PBL tutoring using structured evaluation forms based on a Likert-type scale (poor to excellent. The prediction of tutoring skills using lecturing skills was statistically analyzed using stepwise linear regression. Results: Among the parameters used to judge lecturing skills, the most important predictor for tutoring skills was subject matter mastery in the lecture by explaining difficult concepts and responding effectively to students' questions. Subject matter mastery in the lecture positively predicted five tutoring skills and accounted for 25% of the variance in overall effectiveness of the PBL tutors (F=22.39, P=0.000. Other important predictors for tutoring skills were providing a relaxed class atmosphere and effective use of audiovisual aids in the lecture. Conclusion: Predicting the tutoring skills based on lecturing skills could have implications for recruiting tutors in PBL medical programs and for tutor training initiatives.

    Skills lab training has become a widespread tool in medical education, and nowadays, skills labs are ubiquitous among medical faculties across the world. An increasingly prevalent didactic approach in skills lab teaching is peer-assisted learning (PAL), which has been shown to be not only effective, but can be considered to be on a par with faculty staff-led training. The aim of the study is to determine whether voluntary preclinical skills teaching by peer tutors is a feasible method for preparing medical students for effective workplace learning in clerkships and to investigate both tutees' and tutors' attitudes towards such an intervention. A voluntary clerkship preparation skills course was designed and delivered. N = 135 pre-clinical medical students visited the training sessions. N = 10 tutors were trained as skills-lab peer tutors. Voluntary clerkship preparation skills courses as well as tutor training were evaluated by acceptance ratings and pre-post self-assessment ratings. Furthermore, qualitative analyses of skills lab tutors' attitudes towards the course were conducted following principles of grounded theory. Results show that a voluntary clerkship preparation skills course is in high demand, is highly accepted and leads to significant changes in self-assessment ratings. Regarding qualitative analysis of tutor statements, clerkship preparation skills courses were considered to be a helpful and necessary asset to preclinical medical education, which benefits from the tutors' own clerkship experiences and a high standardization of training. Tutor training is also highly accepted and regarded as an indispensable tool for peer tutors. Our study shows that the demand for voluntary competence-oriented clerkship preparation is high, and a peer tutor-led skills course as well as tutor training is well accepted. The focused didactic approach for tutor training is perceived to be effective in preparing tutors for their teaching activity in this context. A
