    There is ongoing interest in how and what we teach in physics courses for non-science students, so-called "physics for poets" courses. Art Hobson has effectively argued that teaching science literacy should be a key ingredient in these courses. Hobson uses Jon Millers definition of science literacy, which has two components: first, "a basic…

    It has been planned to give pre-clinical practice in the clinic, so-called inclusive clinical practice phase I, for fifth-grade students in the School of Dentistry, Faculty of Dentistry, Tokyo Medical and Dental University, to give them the clinical training needed to perform dental practice and clinical practicum for comprehensive patient care, namely inclusive clinical practice phase II. This study analyzed the educative efficiency of the class on nosocomial infection control (NIC) by comparing achievements pre- and post-test, and discussed appropriate education planning on the NIC for dental students. Sixty-two fifth-grade students in the 2007 academic year sat the pre- and post-tests; the mean score and standard deviation of these tests were 5.30 +/- 1.26 (n = 56) and 8.59 +/- 1.18 (n = 59), respectively. There was a statistically significant difference between them (paired t-test, p < 0.01). Another finding was that students with high scores in the post-test did not necessarily achieve high ratings in the pre-test. It is suggested that the introduction of pre- and post-tests and the clarification of main points in the class as a theme of NIC could be a useful tool for increasing the comprehension of students on the theme. Since students at lower grades will attend clinical practice in the university hospital, it is thought that students should be given NIC training early in the clinical course, and the current curriculum should be improved to increase the opportunity for students to study this important issue.

    Twenty-four patients with unexplained somatic complaints were subjected to a thorough somatic examination. Only when the examination proved negative was the patient entered into the study. The patients were clinically appraised according to criteria given in DSM-III. Generalized anxiety disorder (GAD) was diagnosed in 12, somatization disorder (SD) in 8, and hypochondriasis in 4 patients. Seventeen of the 24 patients agreed to participate in biochemical investigations including a TRH load, a dexamethasone test, and a determination of the monoamine metabolites 5-HIAA and HVA in cerebrospinal fluid (CSF). A normal TSH increase and a normal suppression of cortisol were registered. The HVA values correlated significantly with the 5-HIAA values as well as with the alexithymia scores. Concerning alexithymia and maturity level, no difference as to social class was found. The patients filled in a Zung depression chart. The Zung scale and the 5-HIAA values were both inconsistent with depressive illness. In so-called hypochondriasis a long-term relationship, including selected somatic and biochemical examinations and thorough information, was crucial in abating the patient's distrust and thus the need for health care.

    We have studied 438 patients radiologically in order to observe the so-called 'radius-capitellum axis'. In about a quarter of people with normal elbows the axis passes lateral to the middle portion of the capitellum, so that even when there is marked deviation, there is no certainty that the humero-radial joint is abnormal. Deviation of the axis can be caused by changes in the shape of the capitellum or of the radius, or by distension of the capsule of the elbow joint, or by various changes in muscular pull. (orig.)

    This study is dealing with the so-called Testament of Hippocrates, a short ethic about the doctor's background, knowledge, character, appearance and behaviour towards the patient. Along with the three well-known Greek manuscripts the author is looking at two other by now unknown codices, so that the two Greek versions are accompanied by a third and larger version. After a careful consideration of the relations between the different versions he is discussing all readings of the codices explaining the terms within the background of the history of medicine. At the end he is presenting a reconstruction of the Greek original together with a German translation.

  7. Explaining the so-called 'price premium' in oil markets

    2005-01-01

    This paper explores the information content of several variables on the so-called ''oil price premium over fundamentals''. We define this premium as the difference between the market oil price and the estimated price consistent with the OECD's relative industry stock level. By using Granger causality tests and extended regressions we test the systematic ability of a broad set of variables to explain the premium. We find that speculation in the oil market - measured by non-commercial long positions - can improve the traditional model, reducing the premium significantly during some parts of the sample.

    1985-01-01

    CT picture of the shoulder joint was analyzed in 124 shoulders (114 patients). A line perpendicular to a given line between the precornu of acetabular tegmen (A) and the postcornu of acetabular tegmen (B) was drawn and the intersection where the line and the caput humeri meet (C) was obtained. The angle of CAB was defined as the backward angular aperture of the acetabular tegmen. The angular aperture was 26.2 0 +-1.9 in 16 so-called loose shoulders, 17.3 0 +-1.0 in 28 loose shoulders restricted to the inward rotation, and 12.2 0 +-0.4 in 80 normal shoulders, showing a distinct correlation between the angular aperture and the degree of loose shoulder. An increased backward angular aperture of the acetabular tegmen was considered greatly attributable to the forward glenohumeral movement resulting from malformation of the acetabular tegmen and flaccidity of the joint. Glenoid osteotomy was thus performed in 9 patients, 6 of whom underwent CT scanning before and after osteotomy. Coronal and transverse CT images of the shoulder joint disclosed a noticeable improvement of the glenohumeral alignment. The angular aperture shown on CT seems to be of major importance not only in the diagnosis of so-called loose shoulder but also in surgical choice. (Namekawa, K.)

    Previous research has documented students' conceptual difficulties learning evolution and how student learning may be related to students' views of evolution and science. This mixed methods study addressed how 74 high school biology students from six Indiana high schools viewed their evolution learning experiences, the demarcations of science from non-science, and evolution understanding and acceptance. Data collection entailed qualitative and quantitative methods including interviews, classroom observations, surveys, and assessments to address students' views of science and non-science, evolution learning experiences, and understanding and acceptance of evolution. Qualitative coding generated several demarcation and evolution learning experience codes that were subsequently used in quantitative comparisons of evolution understanding and acceptance. The majority of students viewed science as empirical, tentative but ultimately leading to certain truth, compatible with religion, the product of experimental work, and the product of human creativity. None of the students offered the consensus NOS view that scientific theories are substantiated explanations of phenomena while scientific laws state relationships or patterns between phenomena. About half the students indicated that scientific knowledge was subjectively and socio-culturally influenced. The majority of students also indicated that they had positive evolution learning experiences and thought evolution should be taught in secondary school. The quantitative comparisons revealed how students who viewed scientific knowledge as subjectively and socio-culturally influenced had higher understanding than their peers. Furthermore, students who maintained that science and religion were compatible did not differ with respect to understanding but had higher acceptance than their peers who viewed science and religion as conflicting. Furthermore, students who maintained that science must be consistent with their

    Scand J Caring Sci; 2011 Emotional distance to so-called difficult patients Purpose: To explore nurses' relationships with patients they regard as being difficult. How do nurses feel about such patients and relate to them, and what are the consequences for nurse and patient? Design and methods....... Patients' case records were studied and four meetings with the staff were arranged to discuss the findings. Data collection lasted 18 months in all. Findings: Three strategies were identified: persuasion, avoidance (emotional distance), and compromise. Interestingly, in the relationship with a particular...... patient, the avoidance strategy did not necessarily represent the terminal stage, since a nurse could revert to the compromise strategy. Some of the nurses experienced painful emotions regarding these interactions. Conclusions: The avoidance strategy (emotional distance) resulted in important social...

  11. Courses in Modern Physics for Non-science Majors, Future Science Teachers, and Biology Students

    2001-03-01

    For the past 15 years Kansas State University has offered a course in modern physics for students who are not majoring in physics. This course carries a prerequisite of one physics course so that the students have a basic introduction in classical topics. The majors of students range from liberal arts to engineering. Future secondary science teachers whose first area of teaching is not physics can use the course as part of their study of science. The course has evolved from a lecture format to one which is highly interactive and uses a combination of hands-on activities, tutorials and visualizations, particularly the Visual Quantum Mechanics materials. Another course encourages biology students to continue their physics learning beyond the introductory course. Modern Miracle Medical Machines introduces the basic physics which underlie diagnosis techniques such as MRI and PET and laser surgical techniques.

  12. Using the Theme of Mass Extinctions to Teach Science to Non-Science Major College and University Students

    Science.gov (United States)

    Boness, D. A.

    2013-12-01

    The general public is heavily exposed to "news" and commentary---and arts and entertainment---that either inadvertently misrepresents science or even acts to undermine it. Climate change denial and evolution denial is well funded and pervasive. Even university-educated people get little exposure to the aims, methods, debates, and results of scientific inquiry because unless they earn degrees in science they typically only take one or two introductory science courses at the university level. This presentation reports the development of a new, non-science major Seattle University course on mass extinctions throughout earth history. Seattle University is an urban, Jesuit Catholic university. The topic of mass extinctions was chosen for several reasons: (1) To expose the students to a part of current science that has rich historical roots yet by necessity uses methods and reasoning from geology, geophysics, oceanography, physics, chemistry, biology, and astronomy. This multidisciplinary course provides some coverage of sciences that the student would not typically ever see beyond secondary school. (2) To enable the students to learn enough to follow some of the recent and current debates within science (e.g., mass extinctions by asteroid impact versus massive volcanism, ocean anoxia, and ocean acidification), with the students reading some of the actual literature, such as articles in Science, Nature, or Nature Geoscience. (3) To emphasize the importance of "deep time" as evolutionary biological processes interact with massive environmental change over time scales from hundreds of millions of years down to the seconds and hours of an asteroid or comet strike. (4) To show the effects of climate change in the past, present, and future, due to both natural and anthropogenic causes. (5) To help the student critically evaluate the extent to which their future involves a human-caused mass extinction.

    The concept of so-called eosinophilic sinusitis has recently come to be understood, but since the definition and the diagnostic criteria for this intractable form of sinusitis are unclear, we reviewed the clinical features of 104 patients (16 with eosinophilic sinusitis and 88 with non-eosionphilic sinusitis) who underwent endonasal sinus surgery in our department. So-called eosinophilic sinusitis was usually accompanied by severe bronchial asthma, and the characteristic clinical findings of so-called eosinophilic sinusitis were an increase in peripheral blood eosinophil count, a paranasal sinus shadow in computed tomograms (CT score), and a high ethmoid sinus/maxillary sinus score ratio (E/M ratio) in our study. We determined the cutoff value to review sensitivity, specificity and correct diagnosis rate in screening for eosinophilic sinusitis. When we judged using three cutoff values, a peripheral blood eosinophil count≥500/μ1, CT score≥13 and E/M ratio≥1, a sensitivity of 69%, specificity of 97% and correct diagnosis rate of 81%. On the other hand, when we judged using two cutoff value, peripheral blood eosinophil count≥500/μ1 and E/M ratio≥1, sensitivity of 75%, specificity of 94% and correct diagnosis rate of 88%. Because all three studies can be performed in outpatient clinics, we concluded that they are useful as a method of screening for so-called eosinophilic sinusitis without the need for histological examinations for eosinophil infiltration of nasal polyps in biopsy specimens.

    When performing a 201 Tl-sup(99m)Tc subtraction scan of the parathyroids in a patient with secondary hyperparathyroidism, a marked accumulation of 201 Tl was observed in a so-called brown tumour of the mandible. The 201 Tl uptake can probably be explained by the rich vascularity and the high cellularity of the lesion. (Author)

    2003-12-01

    Titled "Observing Climate Change From Space-what tools do we have?", this non-science major freshman seminar at UCLA is the culmination of a year-long interdisciplinary program sponsored by the Institute of the Environment and the College Honors programs at the University. Focusing on the anthropogenic and natural causes of climate change, students study climate forcings and learn about satellite and other technological means of monitoring climate and weather. NASA's Terra satellite is highlighted as one of the most recent and comprehensive monitoring systems put into space and the role of future NASA platforms in the "A-train"-constellation of satellites is discussed. Course material is typically presented in a Power-Point presentation by the instructor, with assigned supplementary reading to stimulate class discussion. In addition to preparing lectures for class presentation, students work on a final term paper and oral presentation which constitutes the majority of their grade. Field trips to the San Gabriel mountains to take atmospheric measurements with handheld sunphotometers and to JPL, Pasadena (CA) to listen to a NASA scientist discuss the MISR instrument aboard the Terra satellite help bring a real-world perspective to the science learned in the classroom. In this paper, we will describe the objectives and structure of this class and present measurement results taken during the field trip to the San Gabriel Mountains. In this context we will discuss the potential relevance of hands-on experience to meeting class objectives and give a student perspective of the overall class experience.

    2005-11-01

    In this paper, the perspective of situated cognition, which gave rise both to the pragmatic theories and the so-called semantic theories of learning and has probably become the most representative standpoint of constructivism, is examined. We consider the claim of situated cognition to provide alternative explanations of the learning phenomenon to those of psychology and, especially, to those of the symbolic perspective, currently predominant in cognitive psychology. The level of analysis of situated cognition (i.e., global interactive systems) is considered an inappropriate approach to the problem of learning. From our analysis, it is concluded that the pragmatic theories and the so-called semantic theories of learning which originated in situated cognition can hardly be considered alternatives to the psychological learning theories, and they are unlikely to add anything of interest to the learning theory or to contribute to the improvement of our knowledge about the learning phenomenon.

    A 89-year-old woman undergoing fibroptic esophagoscopy elsewhere for dysphagia was found to have an esophageal tumor and was referred to our hospital. Upper gastrointestinal endoscopy showed a type 1 esophageal tumor about 3 cm in diameter in the lower thoracic esophagus pathologically diagnosed as moderately differentiated squamous cell carcinoma from the biopsy specimen. CT and MRI showed metastasis in the right lymph node of cardia. Although we advised an esophagectomy, she did not agree to it due to her high age, so we treated her with radiochemotherapy. She underwent radiotherapy (54 Gy) and chemotherapy (cisplatin and 5-fluorouracil (FU)) concurrently. It was effective and the tumor almost disappeared and the biopsy specimen showed few viable cells. After 12 months, the tumor recurred and the pathological diagnosis was so-called carcinosarcoma. She died 14 months after treatment and pathological autopsy showed the tumor of the esophagus to be so-called carcinosarcoma, but metastasized tissue consisted of squamous cell carcinoma and did not have a sarcoma component. We concluded that metaplastic change of squamous carcinoma cells into spindle cells, occurred due to radiochemotherapy and the tumor recurred as so-called carcinosarcoma. (author)

    The use of eponyms honours those who have contributed to the development of medicine and facilitates communication between colleagues. Eponyms are based on historical knowledge to know who was the first to use a given technique. In the previous century, two different operative procedures have been attached to the 'so called' Bernard lower lip reconstruction. This historical literature on lip reconstruction with a focus on the years 1853-1855 elucidates the roles of Bernard, Saeman, Desgranges and Burow, and gives suggestions for eponyms that do justice to the innovating surgeons Bernard, Burow and Desgranges.

  1. Optimizing of verification photographs by using the so-called tangential field technique

    Proske, H.; Merte, H.; Kratz, H.

    1991-01-01

    When irradiating under high voltage condition, verification photographs prove to be difficult to take if the Gantry position is not aligned to 0deg respectively 180deg, since the patient is being irradiated diagonally. Under these conditions it is extremely difficult to align the X-ray-cartridge vertically to the central beam of the therapeutic radiation. This results in, amongst others, misprojections, so that definite dimensions of portrayed organ structures become practical impossible to determine. This paper describes how we have solved these problems on our high voltage units (tele-gamma cobalt unit and linear-accelerator). By using simple accessories, determination of dimensions of organ structures, as shown on the verification photographs, are made possible. We illustrate our method by using the so-called tangential fields technique when irradiating mamma carcinoma. (orig.) [de

    1980-01-01

    A woman 63 years old had received an unknown amount of roentgen rediation from a physician for spondylitis tuberculosa of the thoracic vertebrae fifty years ago. About five years ago two small brownish black tumors appeared on her back and gradually increased. Within the past month ulcer and bleeding in these tumors. The Patient presented a chronic radiodermatitis (so-called roentgen-skin) of the interscapular space. In addition, two tumors were present in the upper and lower parts of the roentgen-skin. The upper tumor revealed adenoid basal cell epithelioma and the lower tumor was pigmented solid basal cell epithelioma. A view on the development of basal cell epitheliomas on the roentgen-skin was assumed as follows: When epidermal and adnexal cells suffer from a certain damage by X-ray, especially soft X-ray, these cells may become modulated cells which have the same functions as adult immature pluripotential cells. From these modulated cells, basal cell epitheliomas may develop. (author)

    Modern cultural trends are inclined to recognise to all human beings an always more ample right to become involved directly in choices affecting them. This even when health is concerned thus requiring expertise not always accessible to all. Informed consent to often gets reduced to a mere formality, having a mostly defensive purpose for the physician. Patients' education is becoming an ever more pressing issue in order to safeguard decision rights and the effective knowledge of the implications of every decision simultaneously. Patients' education has serious ethical implications which can't be eluded nor referred outside as happens when we let mass media inform on the advantages and disadvantages of various therapies. One of the major fields were this misinformed choice right is expressed is the so called complementary and alternative medicine. Nowadays physicians have to get back their therapeutical leadership once again, with renewed responsibility and through education as well. Information as such is a necessary and not sufficient condition. A sheer education involving the physician in a deeper as well as in an extended therapeutical alliance is needed. The challenge of taking care involves the whole human being: his/her sick body, his/her wounded feelings as well as intelligence which has to understand what is happening clearly.

  4. Later Echoes of the So-called Kniazheskii Izbornik in Old Slavic Literatures

    Directory of Open Access Journals (Sweden)

    Anissava Miltenova

    2015-08-01

    Full Text Available There is a proposition in palaeoslavistics that the reconstructed prototype of the Izbornik of 1076 is a composition designated as the Kniazheskii Izbornik, which originated from the time of the Bulgarian Tsar Peter (927–969. This article presents an overview of the contents of three manuscripts, which are copies of texts in the so-called Kniazheskii Izbornik: No. 162 from the collection of the Moscow Theological Academy, from the 15th century, Russian origin; No. 189 from the collection of the Hilandar Monastery and which is composed of two parts: Part 1 from the beginning of the 17th century, probably written by a copyist from Moldavia, and Part 2 from 1684, Russian in origin; and No. 280 (333 from the collection of St. Synod of the Romanian Orthodox Church, 15th–16th century, Moldavian in origin. There are suggestions for primary sources of these manuscripts, and the article considers the paths by which texts identical to the Kniazheskii Izbornik found their way into miscellanies in the Late Middle Ages. The three miscellanies under discussion are important witnesses of the paraenetic literature in the earliest period of the Slavia Orthodoxa, which integrated homilies of John Chrysostom, question and answers, interpretations of the Scripture, wise sayings, narration, and apophthegmata from the Paterikon and fragments of the Kniazheskii Izbornik.

  5. A critical review of so-called cold sterilization in the field of foods

    Jordy, A.

    1985-01-01

    The contamination of raw materials with microorganisms is a potential hazard to human health, especially if these materials are kept for a certain time under conditions that enhance microbial multiplication. Since the goods in question are by no means cheap bulk materials, but are highly ranked substances, the method of germ reduction by heat treatment is not suitable, and various so-called cold sterilizations have to be used (chemical, irradiation). The article examines the value of these, and in particular how they are assessed. Until the sixties, it was mainly the microbicidal effect of these treatments that was judged; today, the emphasis is on the assessment of the secondary reactions of the agents with the treated commodity and in particular their residual toxicity. In the case of chemical treatments, toxicity is determined directly by application of overdoses. It should be stressed that this is not comparable with the indirect assessment of the toxicity of gamma irradiation, by feeding irradiated goods. Of the available chemosterilants, formaldehyde has great disadvantages in spite of its high volatility, because of its high protein factor and its delayed vaporization from surfaces, due to polymerization. Propylene oxide is less active, requiring higher concentrations, which in turn results in increased residues. Therefore, the agent of choice is still ethylene oxide, since it diffuses quickly and is highly reactive; selection of genetically resistant microorganisms is therefore not possible, as opposed to the case of gamma radiation

  6. Studies on so-called redistribution phenomenon of cerebral blood flow imaging

    International Nuclear Information System (INIS)

    Oba, Hiroshi

    1989-01-01

    To elucidate the relationship between so-called redistribution phenomenon and metabolism or viability of the brain tissue, a new quantitative triple-radionuclide autoradiography was developed, whereby making it possible to compare both late images and reditribution of IMP with cerebral metabolism in experimentally induced unilateral ischemic brain tissue of rats. Iodine-123 IMP and I-125 IMP were used as tracers for early and late imaging, and H-3 amino acid mixture or H-3 H-2 deoxyglucose as a tracer for protein synthesis or glucose metabolism imaging. There was no significant relationship between redistribution index and protein synthesis or glucose metabolism. Protein synthesis was remarkably decreased in the affected hemisphere regardless of redistribution index values. Although the redistribution indices showed a gentle peak at approximately 34 μ mol/100 g/ min of glucose metabolism, there was no obvious relationship between either late images or redistribution index images and glucose metabolism images. Redistribution indices showed a maximum value at approximately 40 to 50 ml/100 g/min of cerebral blood flow. Reverse redistribution was observed with 160 ml/100 g/min or more of flow. Thin layer chromatographic findings were similar in the affected and non-affected resions, suggesting redistribution of a lipophilic IMP metabolite of p-iodoamphetamine in the affected region. In vitro autoradiography revealed no significant reduction in binding ability of IMP to the affected ischemic cortex. In a computer simulation study for brain activity curve, brain activity at 150 min was found to be almost constant at more than 25 ml/100 g/min of flow. IMP redistribution was unlikely to reflect directly either brain metabolism or function, and both blood flow partition coefficient and blood flow values were independently responsible for cerebral kinetics of IMP.

  7. Conceptual change through the use of student-generated analogies of photosynthesis and respiration by college non-science majors

    Science.gov (United States)

    Hill, Gary D.

    Two of the most important and difficult concepts in biology are photosynthesis and respiration. A pilot study was performed using student volunteers from introductory biology classes to assess student alternative frameworks regarding photosynthesis and respiration. The results of the pilot study were used to construct the Instrument for the Assessment of Respiration and Photosynthesis (IFARP). This was an 11-item, three-tier multiple choice instrument designed to conveniently assess the common misconceptions students have about these concepts upon entering a biology course. The first tier of each item of the IFARP contained a multiple choice question about photosynthesis or respiration. The second tier had a multiple choice question regarding the reason for the choice in the first tier. The third tier asked the students to indicate how confident they were in their responses, on a scale from 1 (not very confident) to 5 (very confident). The IFARP was administered as a pretest and posttest to a group of science non-majors in an introductory biology course. No significant changes were observed in student performance as measured by the IFARP between the pretest and posttest administrations. The students did, however, demonstrate a statistical increase in mean confidence levels regarding their knowledge of photosynthesis and respiration. Even though their comprehension and understanding regarding photosynthesis and respiration had not increased, the confidence they had in their responses about these two concepts had increased. The IFARP was also administered to a group of nursing student volunteers in an introductory microbiology course. This group of students also participated in the use of student-generated analogies as a learning strategy to alter conceptual frameworks. One test group of students provided analogies to photosynthesis and respiration, while the other test group provided analogies to two other concepts. No significant changes were observed in the

Stylistically, it combines memoir with the genre known as "creative non-fiction." Its major issues have to do with the identity formation and transformation of the author, the function and ethics of institutional review boards, the teaching of medical ethics to medical students, and courses involved in the doctor-patient relationship and in palliative care intended to increase the sensitivity and self-awareness of physicians-in-becoming. This essay was presented in its initial form at the Annual Fellows Meeting of the Society for Values in Higher Education in 2010.

    Full Text Available There are conflicting claims among scholars on whether the structural outputs of the types of English spoken in countries where English is used as a second language gives such speech forms the status of varieties of English. This study examined those morphological features considered to be marked features of the variety spoken in Nigeria according to Kirkpatrick (2011 and the variety spoken in Malaysia by considering the claims of the Missing Surface Inflection Hypothesis (MSIH a Second Language Acquisition theory which accounts for the cause of the variable use of such inflections among L2 learners. Results from oral and written composition tasks administered on selected undergraduate students of Nigerian and Malaysian universities revealed that what is regarded as morphological features are actually a deviation from the L2 target forms. According to the MSIH the variability in the use of such inflections is due to problems of lexical retrieval a psycholinguistic problem which manifests among L2 learners of English generally which results in wrong surface representations.

    Abstract As media consumption grows increasingly niche and distribution extends further away from old network and print models, media producers continue to hone their marketing toward ever more specific audiences. Yet, while fan-centred franchises and crowdfunding projects have garnered some scholarly attention, there has been less discussion of the ways that gender, race, and sexuality intersect with media production and marketing. This paper analyses the crowdfunded comic My So-Called Secre...

    Full Text Available We report female patient, age 51, with clinically definitive multiple sclerosis (CDMS since 1998, who underwent two PTA procedures with stent implantation for CCSVI in 2010. Expanded disability status scale (EDSS worsened since the procedure from 4.5 to 6. Total number of three stents was implanted (two of them in the right internal jugular vein. In six month time, in 2011, patient was referred for independent examination by computer tomography (CT phlebography for right-sided neck pain. Dislocation of stents on the right side and thrombosis of left sided stent was found. Conservative approach was used so far. Our short report is showing possible complications of PTA and stenting in jugular veins in so called CCSVI and bringing information about neurological state (EDSS worsening in a subject. Continuation of stent migration in the future is probable, possibly resulting in pulmonary embolism with fatal risk for the patient. We strongly ask for restriction of PTA procedure in so called CCSVI, which concept was not proven to be relevant to MS.

    Written to the demand of the ASN to the SFPM (the French professional body in medical physics), this report states the opinion of these professionals regarding the use of the so-called 'transit' dosimetry for the control of the in vivo dose received during radiotherapy. After an overview of the use of in vivo dosimetry in medical practices, the authors outline the main benefits and drawbacks of point conventional detectors used for this dosimetry. They propose an overview of the state-of-the-art in transit in vivo dosimetry by briefly describing the different developed methodologies: the prediction-based methodology and the rear projection methodology. They also propose a literature review on transit in vivo dosimetry. Based on expert experience and on this review they give lists of technical benefits and drawbacks of techniques of in vivo dosimetry by EPID transit imagery. They finally indicate some commercially available technical solutions to transit in vivo dosimetry

  13. An enigmatic graffito from the sun temple of Nyuserre and the meaning of the so-called “slaughterhouse”

    Full Text Available For a long time the presence of a “slaughterhouse” in the sun temple of Nyuserre has been taken for granted as the result of the investigation conducted by Ludwig Borchardt in Abu Ghurab in 1898–1901. However, several pieces of archaeological and textual evidence, including the documents from the Abusir papyri, which are contemporary with the sun temples, challenge this reconstruction. An important element in this discussion may probably come from the correct reading and interpretation of a hieratic inscription found inside the so-called “slaughterhouse” and later on completely forgotten. To this inscription, and the important institutions mentioned therein, we shall pay attention in this article.

  14. On the so-called membrane coating granules in keratinized lichen planus lesions of the buccal mucosa.

    1982-11-01

    Serial sections of the so-called membrane-coating granules have been examined in keratinized oral epithelium of lichen planus lesions. As with 'granules' apparent in non-keratinized epithelium, it is found they do not represent specialized intra-cytoplasmic organelles, but are the result of sectioning at different areas, levels and planes through the plasma membrane of interdigitating cell processes. Such 'granules' appear mostly in the superficial, but not deep, part of the cytoplasm of the upper prickle cells. This is considered to be due to topographic differences between the upper and under surfaces of these cells and the presence of narrower intercellular spaces than those between deeper epithelial cells. Such arrangement often results in cell processes in sections appearing free in the superficial part of the cell below. The appearance of 'granules' arises when the plane of section is not at right angles to the two plasma membranes surrounding these processes.

    Full Text Available Abstract Background To demonstrate the tobacco industry rationale behind the "Spanish model" on non-smokers' protection in hospitality venues and the impact it had on some European and Latin American countries between 2006 and 2011. Methods Tobacco industry documents research triangulated against news and media reports. Results As an alternative to the successful implementation of 100% smoke-free policies, several European and Latin American countries introduced partial smoking bans based on the so-called "Spanish model", a legal framework widely advocated by parts of the hospitality industry with striking similarities to "accommodation programmes" promoted by the tobacco industry in the late 1990s. These developments started with the implementation of the Spanish tobacco control law (Ley 28/2005 in 2006 and have increased since then. Conclusion The Spanish experience demonstrates that partial smoking bans often resemble tobacco industry strategies and are used to spread a failed approach on international level. Researchers, advocates and policy makers should be aware of this ineffective policy.

    Although the medical literature currently provides a growing number of isolated case reports of patients with clinically well-defined antiphospholipid syndrome (APS) and persistently negative antiphospholipid antibodies (aPL), there are no studies including a series of patients addressing the clinical features of this condition. The authors assessed clinical manifestations of APS in 154 patients: 87 patients with seropositive APS and 67 patients with thrombosis and/or pregnancy morbidity persistently negative for aPL and presenting with at least two additional non-criteria manifestations of APS (the so-called 'seronegative APS', SN-APS). Patients were interviewed at the time of recruitment, and a retrospective file review was carried out. There were no significant differences in the frequency of thrombotic events or obstetric morbidity in patients with SN-APS versus patients with seropositive APS: deep vein thrombosis (31.4% vs 31.0%), pulmonary embolism (23.8% vs 28.7%), stroke (14.9% vs 17.2%), transient ischaemic attack (11.9% vs 10.3%), early spontaneous abortions (67.1% vs 52.1%), stillbirths (62.5% vs 59.4%), prematurity (28.1% vs 21.7%) or pre-eclampsia (28.1% vs 23.1%). Classic and SN-APS patients show similar clinical profiles. The results suggest that clinical management in patients with APS should not be based only on the presence of conventional aPL.

  18. The so-called "Pre-Levantine" phase and the chronology of the Levantine Rock Painting. A critical review

    Mateo Saura, Miguel Ángel

    2002-06-01

    Full Text Available The rejection of the principles on which the so-called "prelevantine phase" is based and the discussion about the neolithic material culture parallels for levantine art allow its attribution to Epipaleolithic groups of hunters and gatherers. In the same way, the data on the process of transition between the Epipaleolithic and the Neolithic, and the relationship between the levantine style and the schematic rock painting seem to support a pre-neolithic chronology of the levantine art, related to non-producing ways of living.

    El rechazo de las bases en las que se sustenta la llamada "fase pre-levantina" y la discusión de los paralelos mobiliares neolíticos propuestos para el arte levantino dejan expedito el camino para su adscripción a los grupos de cazadores y recolectores epipaleolíticos. Asimismo, los datos con que contamos sobre el proceso de transición Epipaleolítico/Neolítico, y la relación entre el estilo levantino y la pintura rupestre esquemática parecen abogar también por una cronología pre-neolítica de lo levantino, asociado a unos modos de vida no productores.

  19. Origin of the color of Cv. rhapsody in blue rose and some other so-called "blue" roses.

    Gonnet, Jean-François

    2003-08-13

    Flowers of the rose cultivar Rhapsody in Blue display unusual colors, changing as they age, from a vivid red-purple to a lighter and duller purple, which are based on tonalities corresponding to hue angles between 340 and 320 degrees in the CIELAB scale. Unexpectedly, the chemical basis of these colors is among the simplest, featuring cyanin (cyanidin 3,5-di-O-glucoside), the most frequent anthocyanin in flowers, as the sole pigment and quercetin kaempferol glycosides as copigments at a relatively low copigment/pigment ratio (about 3/1), which usually produces magenta or red shades in roses. This color shift to bluer shades is coupled with the progressive accumulation of cyanin into vacuolar anthocyanic inclusions (AVIs), the occurrence of which increases as the petals grow older. In addition to the normal lambda(max) of cyanin at approximately 545 nm, the transmission spectra of live petals and of epidermal cells exhibit a second lambda(max) in the 620-625 nm range, the relative importance increasing with the presence of AVIs. In petals of fully opened flowers, the only pigmented structures in the vacuoles of epidermal cells are AVIs; their intense and massive absorption in the 520-640 nm area produces a much darker and bluer color than measured for the vacuolar solution present at the very first opening stage. Cyanin is probably "trapped" into AVIs at higher concentrations than would be possible in a vacuolar solution and in quinonoidal form, appearing purple-blue because of additional absorption in the 580-630 nm area. Quite similar pigmentation features were found in very ancient rose cultivars (cv. L'Evêque or Bleu Magenta), also displaying this type of so-called "blue" color.

    Nicotin- and the so-called pyrazinamidase (in the following: "pyrazinamidase") have been found in strains of four mycobacteria species, M. fortuitum, M. gastri, M. bovis and M. microti. These findings are in contradiction to those summarized in Bergey's Manual of Determinative Bacteriology (1974). The reason for the discrepancies is that the original method (Bönicke, 1961) for amidase determination has not taken the following aspects into consideration: a) The inducibility of the nicotin- and "pyrazinamidase" (example: M. fortuitum); b) The temperature sensitivity of these enzymes (M. gastri); c) The light sensitivity of nicotinamidase (in photochromogenic M. gastri strains); d) The optimal substrate concentration which must be at least 4 mM instead of 0,8 mm. The following consequences can be drawn for the taxonomy and biochemistry of the tested organisms: e) The species status of M. gastri should be annuled. The main difference between M. gastri and M. kansasii consists only of the non-agglutinability of M. gastri by anti-M. kansasii serum. "Pyrazinamidase" and also nitrate reductase (Tarnok et al., in press) are positive in strains of both species; f) M. bovis possesses nicotin- and "pyrazinamidase" as M. tuberculosis too. Thus, these two species are more closely related than suggested earlier; g) Till now, no Mycobacterium has been found showing nicotinamidase without "pyrazinamidase" activity (or vice versa). It seems to be very probable that nicotinamidase, an enzyme of low substrate specificity, is able to hydrolyze several compounds with a nicotinamide-like structure such as pyrazinamide. Thus, we suggest the annulment of the term pyrazinamidase or the employment of quotation marks ("pyrazinamidase") to show the fictitious value of this designation.

    Shoichi Kokubun introduced his successful experience with local anesthetic injection at the occipital insertion of the sternocleidomastoid muscle in K-point syndrome. The purpose of this study was to evaluate the short-term and long-term effectiveness of K-point injection and investigate factors affecting treatment results. K-point injection was performed in 58 patients with K-point syndrome at Yeungnam University Medical Center. The syndrome was associated with cervical whiplash injury in 10 patients and was of nonspecific origin in the rest. One milliliter of 2% lidocaine mixed with 1 milliliter of dexamethasone was injected in 50 patients and 2 milliliters of 1% lidocaine alone in the rest. Initially, the severity of local tenderness at the K-point and other tender points was examined and the degree of immediate pain relief effect was assessed within 1 hour after injection. Early effect within 1 month after the injection and current effect were evaluated in 27 patients using a modified Kim's questionnaire with regard to the duration of improvement, degree of improvement in pain and daily living activities, and satisfaction. Of the total 58 patients, 44 (75.8%) apparently had immediate pain relief after K-point injection. The only factor associated with successful immediate pain relief was the whiplash injury associated with traffic accident (TA). The early pain control effect was associated with the immediate effect. The current effect was associated with the early effect alone. Satisfaction with the K-point injection was related to early successful pain relief. K-point injection would be useful for early pain relief in nonspecific neck pain syndrome so called K-point syndrome, but not for current pain relief. Especially, it was very effective for early pain control in the whiplash injury associated with TA.

  2. Top-Down Prioritization of Salient Items May Produce the So-Called Stimulus-Driven Capture

    Full Text Available The current study proposes that top-down attentional prioritization of salient items may produce the so-called stimulus-driven capture. To test this proposal, the “expectation-based paradigm” was designed on the basis of a visual search task. In Experiment 1, a task-irrelevant singleton frame was presented at the same location in 70% of the trials. The target was either presented at chance level within the singleton location, or away from it. In line with the singleton capture phenomenon, participants were faster in identifying the target when it appeared in the singleton location compared to non-singleton locations. However, leaving out the singleton frame in 30% of the trials led to a similar effect; participants were faster in identifying the target when it appeared in the expected singleton location compared to expected non-singletons locations (a “quasi-capture” effect. These results suggest that the participants allocated their attention to the expected singleton location, rather than that the singleton itself captured attention. In Experiment 2, the same task-irrelevant color singleton was presented in a random position in 70% of the trials. This color frame was shown as a non-singleton in all of the 30% singleton-absent multicolored trials. A similar facilitation effect was obtained when the target appeared in the expected singleton color frame compared to other frames, in singleton-absent trials as in singleton-present trials. These results further support the idea that instances of singleton capture can be explained by top-down attentional shifts toward singleton items. Theoretical implications of these results are discussed. Mostly, the study calls to consider the possibility that all sources of attentional control may be represented by a continuous variable of top-down control, including the category of “physical salience.”

  4. A conceptual framework for an ecosystem services-based assessment of the so-called "emergency stabilization" measures following wildfire

    Wildfires have become a major environmental concern in many Southern European countries over the past few decades. This includes Portugal, where, on average, some 100 000 ha of rural lands are affected by wildfire every year. While policies, laws, plans and public expenditure in Portugal continue to be largely directed towards fire combat and, arguably, to a lesser extent fire prevention, there has only recently been increasing attention for post-fire land management. For example following frequent and several large wildfires during the summer of 2010, so-called emergency stabilization measures were implemented in 16 different burnt areas in northern and central Portugal, using funds of the EU Rural Development Plan in Portugal (PRODER). The measures that were implemented included mulching (i.e. application of a protective layer of organic material), seeding and the construction of log barriers. However, the effectiveness of the implemented measures has not been monitored or otherwise assessed in a systematic manner. In fact, until very recently none of the post-fire emergency stabilization measures contemplated under PRODER seem to have been studied in an exhaustive manner in Portugal, whether under laboratory or field conditions. Prats et al. (2012, 2013, 2014) tested two of these measures by field trials, i.e. hydro-mulching and forest residue mulching. The authors found both measures to be highly effective in terms of reducing overland flow and especially erosion. It remains a challenge, however, to assess the effectiveness of these and other measures in a broader context, not only beyond overland flow and sediment losses but also beyond the spatio-temporal scale that are typical for such field trials (plots and the first two years after fire). This challenge will be addressed in the Portuguese case study of the RECARE project. Nonetheless, the present study wants to be a first attempt at an ecosystem services-based assessment of mulching as a post

    Full Text Available Taking into account recent critiques of "underdevelopment", "positivism", "methodological backwardness" and other failings attributed to socalled "American Anthropology" by some of the authors from the Belgrade Structural-semiotic School of Anthropology of Folklore, I analyse the context in which colleagues and students may be tempted to explain common sense political connection between polyphone ethnography, neo-romanticism and nationalism as counter-intuitive history of the discipline. I already pointed that the important transformative differences in the attitudes towards structuralism between European anthropologists, especially Belgrade Structural-semiotic School of Anthropology of Folklore and so called "American Anthropology", are the consequence of a pure coincidence – the fact that French structuralism and French poststructuralism were launched simultaneously at the American interdisciplinary intellectual scene ("Theory" at the same conference. This ironic concurrence would not be much more than one entertaining episode for students, historians of anthropology and historians of ideas, if there were no attempts (more and more frequent and increasingly fluently articulated to compare different intellectual traditions as they were elements of the same unilineal evolution of the discipline. Belgrade Structural-semiotic School (further called only SS and especially its spiritus movens and most prominent representative Prof. Kovačević started in recent years to criticise some "American Anthropology" measuring its academic "achievement" (the author’s term in comparative perspective and taking as an analytical unit uncritically generalized traditions marked with a single term of "postmodern anthropology" on the one hand, and "anthropology" on the other.

    The purpose of this study was to evaluate the effect of cooperative learning strategies on students' attitudes toward science and achievement in BSC 1005L, a non-science majors' general biology laboratory course at an urban community college. Data were gathered on the participants' attitudes toward science and cognitive biology level pre and post treatment in BSC 1005L. Elements of the Learning Together model developed by Johnson and Johnson and the Student Team-Achievement Divisions model created by Slavin were incorporated into the experimental sections of BSC 1005L. Four sections of BSC 1005L participated in this study. Participants were enrolled in the 1998 spring (January) term. Students met weekly in a two hour laboratory session. The treatment was administered to the experimental group over a ten week period. A quasi-experimental pretest-posttest control group design was used. Students in the cooperative learning group (nsb1 = 27) were administered the Test of Science-Related Attitudes (TOSRA) and the cognitive biology test at the same time as the control group (nsb2 = 19) (at the beginning and end of the term). Statistical analyses confirmed that both groups were equivalent regarding ethnicity, gender, college grade point average and number of absences. Independent sample t-tests performed on pretest mean scores indicated no significant differences in the TOSRA scale two or biology knowledge between the cooperative learning group and the control group. The scores of TOSRA scales: one, three, four, five, six, and seven were significantly lower in the cooperative learning group. Independent sample t-tests of the mean score differences did not show any significant differences in posttest attitudes toward science or biology knowledge between the two groups. Paired t-tests did not indicate any significant differences on the TOSRA or biology knowledge within the cooperative learning group. Paired t-tests did show significant differences within the control group

    Full Text Available Cancerology is, by all counts, a non-science, which may be defined as a so-called scientific pursuit in the teeth of obvious proofs to the contrary. Not one facet of current cancerology-etiology, diagnosis, therapy, prevention, and its latest fad, immunology -enjoys any clear, rational basis. No wonder that the outcome of the whole gargantuan effort is "precisely nil", with possibly more people living on, than dying of, cancer. The pathway to the logical-ly acceptable and comprehensible science is simple-to give cancer its due place in biology, to give the cancer cell its rightful place of but a form of cytodifferentiation, and to give the cancer therapist the supremely relevant role of a palliator. To talk of cancer cure is to deny - the cytosomatic reality that cancer is one′s own flesh and blood. Being a part of one′s self, cancer need not always be treated. I f a therapist has the right and obligation to diagnose, treat, and prognose upon a cancer patient, he has, hitherto unrecognized, equal right and obligation, not to do one or all of these. Cancer-realism offered in this article can guide a therapist to this often necessary path of inaction.

    Decontamination property of the so-called manganese-zeolite which was made from montmorillonite was studied by a column method. The following results were obtained: (1) /sup 54/Mn or /sup 59/Fe is removed completely. (2) /sup 60/Co or /sup 137/Cs is removed effectively. It is attributed to the adsorption on a broken-bond of quartz or feldsper. (3) Nitro nitrosylruthenium and (RuORu) nitrate are hardly removed, however, a little amount of nitrato nitrosylruthenium is removed. (4) Contact time of radioactive material with manganese-zeolite is the important factor for the removal of radioactive material. Each radioactive material was hardly removed at the contact time less than 20 min.

    Automation offers great opportunities in the efforts of energy utilities in the Netherlands to reorganize towards more customer-oriented businesses. However, automation in itself is not enough. First, the organizational structure has to be changed considerably. Various energy utilities have already started on it. The restructuring principle is the same everywhere, but the way it is implemented differs widely. In this article attention is paid to different customer information systems. These systems can put an end to the so-called island culture within the energy utility organizations. The systems discussed are IRD of Systema and RIVA of SAP (both German software businesses), and two Dutch systems: Numis-2000 of Multihouse and KIS/400 of NUON Info-Systemen

    1989-04-01

    We describe the patterns of omissions (and substitutions) of freestanding grammatical morphemes and the patterns of substitutions of bound grammatical morphemes in 20 so-called agrammatic patients. Extreme variation was observed in the patterns of omissions and substitutions of grammatical morphemes, both in terms of the distribution of errors for different grammatical morphemes as well as in terms of the distribution of omissions versus substitutions. Results are discussed in the context of current debates concerning the possibility of a theoretically motivated distinction between the clinical categories of agrammatism and paragrammatism and, more generally, concerning the theoretical usefulness of any clinical category. The conclusion is reached that the observed heterogeneity in the production of grammatical morphemes among putatively agrammatic patients renders the clinical category of agrammatism, and by extension all other clinical categories from the classical classification scheme (e.g., Broca's aphasia, Wernicke's aphasia, and so forth) to more recent classificatory attempts (e.g., surface dyslexia, deep dysgraphia, and so forth), theoretically useless.

    We describe a case of human Becker muscular dystrophy (BMD)-like myopathy that was characterized by the declined stainability of dystrophin at sarcolemma in a pig and the immunostaining for dystrophin on the formalin-fixed, paraffin-embedded (FFPE) tissue. The present case was found in a meat inspection center. The pig looked appeared healthy at the ante-mortem inspection. Muscular abnormalities were detected after carcass dressing as pale, discolored skeletal muscles with prominent fat infiltrations and considered so-called "fatty muscular dystrophy". Microscopic examination revealed following characteristics: diffused fat infiltration into the skeletal muscle and degeneration and regeneration of the remaining skeletal muscle fibers. Any lesions that were suspected of neurogenic atrophy, traumatic muscular degeneration, glycogen storage disease or other porcine muscular disorders were not observed. The immunostaining for dystrophin was conducted and confirmed to be applicable on FFPE porcine muscular tissues and revealed diminished stainability of dystrophin at the sarcolemma in the present case. Based on the histological observations and immunostaining results, the present case was diagnosed with BMD-like myopathy associated with dystrophin abnormality in a pig. Although the genetic properties were not clear, the present BMD-like myopathy implied the occurrence of dystrophinopathy in pigs. To the best of our knowledge, this is the first report of a natural case of myopathy associated with dystrophin abnormalities in a pig.

    To study the clonality of polygonal cells and surface cuboidal cells in the so-called pulmonary sclerosing hemangioma (PSH). 17 female surgically resected PSH were found. The polygonal cells and surface cuboidal cells of the 17 PSH cases were microdissected from routine hematoxylin and eosin-stained sections. Genomic DNA was extracted, pretreated through incubation with methylation-sensitive restrictive endonuclease HhaI or HpaII, and amplified by nested polymerase chain reaction for X chromosome-linked androgen receptor (AR) and phosphoglycerate kinase (PGK) genes. The length polymorphism of AR gene was demonstrated by denaturing polyacrylamide gel electrophoresis and silver staining. The PGK gene products were treated with Bst XI and resolved on agarose gel. Amongst the 17 female cases of PSH, 15 samples were successfully amplified for AR and PGK genes. The rates of polymorphism were 53% (8/15) and 27% (4/15) for AR and PGK genes respectively. Polygonal cells and surface cuboidal cells of 10 cases which were suitable for clonality study, showed the same loss of alleles (clonality ratio = 0) or unbalanced methylation pattern (clonality ratio < 0.25). The polygonal cells and surface cuboidal cells in PSH demonstrate patterns of monoclonal proliferation, indicating that both represent true neoplastic cells.

    To reduce energy consumption and improve residents' quality of life, "smart cities" should use not only modern technologies, but also the social innovations of the "Internet of Things" (IoT) era. This article attempts to solve transport problems in a smart city's office district by utilizing gamification that incentivizes the carpooling system. The goal of the devised system is to significantly reduce the number of cars, and, consequently, to alleviate traffic jams, as well as to curb pollution and energy consumption. A representative sample of the statistical population of people working in one of the biggest office hubs in Poland (the so-called "Mordor of Warsaw") was surveyed. The collected data were processed using spatial data mining methods, and the results were a set of parameters for the multi-agent system. This approach made it possible to run a series of simulations on a set of 100,000 agents and to select an effective gamification methodology that supports the carpooling process. The implementation of the proposed solutions (a "serious game" variation of urban games) would help to reduce the number of cars by several dozen percent, significantly reduce energy consumption, eliminate traffic jams, and increase the activity of the smart city residents.

    Undescended testis (cryptorchidism) is a common congenital abnormality of male genital organs diagnosed at birth followed with frequent postnatal descensus. However, the so-called isolated true undescended testis (ITUT) diagnosed at the third postnatal month seems to be an independent defect-entity, and this hypothesis was planned to confirm or reject in the study. The evaluation of birth outcomes and maternal socio-demographic data of cases with ITUT in the population-based large dataset of the Hungarian Congenital Abnormality Registry. There was a higher rate of preterm birth and particularly of low birthweight in 2052 cases with ITUT compared to 24,814 population male controls without any defects. The rate of twins was not higher in cases with older mothers, higher birth order and lower socio-economic status. The comparison of data of boys with undescended testis diagnosed at birth found in the previous study and with ITUT in this study confirmed our hypothesis. Undescended testis can be differentiated into two subgroups: boys with frequent postnatal descensus mainly after preterm delivery and boys with ITUT without postnatal testis descensus with frequent intrauterine growth restriction, older mothers with higher birth order and low socio-economic status.

    Microorganisms are known to produce a range of volatile organic compounds, so-called microbial VOC (MVOC). Chamber studies where humans were exposed to MVOC addressed the acute effects of objective and/or subjective signs of mucosal irritation. However, the effect of MVOC on inhabitants due to household exposure is still unclear. The purpose of this epidemiological study was to measure indoor MVOC levels in single family homes and to evaluate the relationship between exposure to them and sick building syndrome (SBS). All inhabitants of the dwellings were given a self-administered questionnaire with standardized questions to assess their symptoms. Air samples were collected and the concentrations of eight selected compounds in indoor air were analyzed by gas chromatography/mass spectrometry - selective ion monitoring mode (GC/MS-SIM). The most frequently detected MVOC was 1-pentanol at a detection rate of 78.6% and geometric mean of 0.60 μg/m 3 . Among 620 participants, 120 (19.4%) reported one or more mucous symptoms; irritation of the eyes, nose, airway, or coughing every week (weekly symptoms), and 30 (4.8%) reported that the symptoms were home-related (home-related symptoms). Weekly symptoms were not associated with any of MVOC, whereas significant associations between home-related mucous symptoms and 1-octen-3-ol (per log 10 -unit: odds ratio (OR) 5.6, 95% confidence interval (CI): 2.1 to 14.8) and 2-pentanol (per log 10 -unit: OR 2.3, 95% CI: 1.0 to 4.9) were obtained after adjustment for gender, age, and smoking. Associations between home-related symptoms and 1-octen-3-ol remained after mutual adjustment. However, concentrations of the selected compounds in indoors were lower than the estimated safety level in animal studies. Thus, the statistically significant association between 1-octen-3-ol may be due to a direct effect of the compounds or the associations may be being associated with other offending compounds. Additional studies are needed to evaluate

    Antiseri, D

    1991-01-01

    The questions discussed in this article concern the demarcation between scientific theories and non scientific theories. The problem is not only an epistemological one, but it implies also ethical and social consequences. For example, is it acceptable for an European country to allow the practice of non-traditional medicines which are not yet considered officially as scientific? According to Karl Popper, the author discusses the following points: 1. Is there a logical asymmetry between the verification and the falsification of a theory? 2. The criterion of falsifiability demarcates science from non-science. 3. There is no automatic method to find new theories. 4. The facts of science are discovered by scientists through theories. 5. The scientific method is only one and it consists of these three steps: problems-theories-refutations. The article's core is that the rational physician is the one who kills (falsifies) his own diagnosis instead of his own patients.

    We describe and demonstrate two laboratory exercises, Kepler's Third Law and Stellar Structure, which are being developed for use in an astronomy laboratory class aimed at non-science majors. The labs run with Microsoft's Excel 98 (Macintosh) or Excel 97 (Windows). They can be run in a classroom setting or in an independent learning environment. The intent of the labs is twofold; first and foremost, students learn the subject matter through a series of informational frames. Next, students enhance their understanding by applying their knowledge in lab procedures, while also gaining familiarity with the use and power of a widely-used software package and scientific tool. No mathematical knowledge beyond basic algebra is required to complete the labs or to understand the computations in the spreadsheets, although the students are exposed to the concepts of numerical integration. The labs are contained in Excel workbook files. In the files are multiple spreadsheets, which contain either a frame with information on how to run the lab, material on the subject, or one or more procedures. Excel's VBA macro language is used to automate the labs. The macros are accessed through button interfaces positioned on the spreadsheets. This is done intentionally so that students can focus on learning the subject matter and the basic spreadsheet features without having to learn advanced Excel features all at once. Students open the file and progress through the informational frames to the procedures. After each procedure, student comments and data are automatically recorded in a preformatted Lab Report spreadsheet. Once all procedures have been completed, the student is prompted for a filename in which to save their Lab Report. The lab reports can then be printed or emailed to the instructor. The files will have full worksheet and workbook protection, and will have a "redo" feature at the end of the lab for students who want to repeat a procedure.

    Cholangiocarcinoma (CC) arising from the large intrahepatic bile ducts and extrahepatic hilar bile ducts share clinicopathological features and have been called hilar and perihilar CC as a group. However, "hilar and perihilar CC" are also used to refer exclusively to the intrahepatic hilar type CC or, more commonly, the extrahepatic hilar CC. Grossly, a major distinction can be made between papillary and non-papillary tumors. Histologically, most hilar CCs are well to moderately differentiated conventional type (biliary) carcinomas. Immunohistochemically, CK7, CK20, CEA and MUC1 are normally expressed, being MUC2 positive in less than 50% of cases. Two main premalignant lesions are known: biliary intraepithelial neoplasia (BilIN) and intraductal papillary neoplasm of the biliary tract (IPNB). IPNB includes the lesions previously named biliary papillomatosis and papillary carcinoma. A series of 29 resected hilar CC from our archives is reviewed. Most (82.8%) were conventional type adenocarcinomas, mostly well to moderately differentiated, although with a broad morphological spectrum; three cases exhibited a poorly differentiated cell component resembling signet ring cells. IPNB was observed in 5 (17.2%), four of them with an associated invasive carcinoma. A clear cell type carcinoma, an adenosquamous carcinoma and two gastric foveolar type carcinomas were observed.

    Human observers are apparently well able to judge properties of 'three-dimensional objects' on the basis of flat pictures such as photographs of physical objects. They obtain this 'pictorial relief' without much conscious effort and with little interference from the (flat) picture surface. Methods for 'magnifying' pictorial relief from single pictures include viewing instructions as well as a variety of monocular and binocular 'viewboxes'. Such devices are reputed to yield highly increased pictorial depth, though no methodologies for the objective verification of such claims exist. A binocular viewbox has been reconstructed and pictorial relief under monocular, 'synoptic', and natural binocular viewing is described. The results corroborate and go beyond early introspective reports and turn out to pose intriguing problems for modern research.

    It is known that in quantum mechanics the act of observing the experiment can affect the experimental findings in some cases. In particular, it happens under the so-called Zeno effect. In this work it is shown that in contrast to the "standard" Zeno-effect where the act of observing a process reduces the probability of its reality, an inverse situation when a particle transmits through a potential barrier (a so-called barrier anti-Zeno effect) can be observed, the observation of the particle essentially increases the probability of its transmission through the barrier. The possibility of using the barrier anti-Zeno effect is discussed to explain paradoxical results of experiments on "cold nuclear fusion" observed in various systems including biological ones. (According to the observers who performed the observations, the energy generation, which could not be explained by any chemical processes, as well as the change in the isotope and even element composition of the studied object may occur in these systems.

    Full Text Available The conservation of so called-marble ornaments is a very important cultural heritage issue, since this kind of decoration was widely use for casing stone buildings during 19th and beginning of 20th centuries in Egypt. The wide variation of materials and techniques used for imitating natural marble is a really big challenge for conservators. Actually most of so called- marble decorations are subjected to several degradation agents which can lead to the loss of material cohesion mostly caused by alteration phenomena that often produce the detachment of large areas of imitated marble ornaments. Surface consolidation, directed to achieve cohesion and stability, is based on the use of materials with aggregating properties. This study started with characterization of the yellow veined imitated marble stucco used in Hosh Al Basha courtyard dating back to Mohammed Ali's family period (1805-1952 in Egypt. The imitated marble stucco consists of two main layers. The outer finishing layer, yellow paint veined with brown color, composed mainly of yellow zincite (ZnO. Gypsum (CaSO4.2H2O, halite (NaCl and calcite (CaCo3 were detected in this layer also. The mineral composition of the subsurface layer (prime layer shows the presence of gypsum (major mineral, zincite (ZnO, anhydrite (CaSO4 and halite (NaCl were also detected. Two products (Paraloid B-72 and SILRES® BS OH 100 were selected to evaluate their efficiency for consolidation treatments of imitated marble stucco. The selected products were tested under thermal ageing. Polarizing microscope (PLM, scanning electron microscopy with the energy dispersive X-ray (SEM-EDX, X-ray diffraction (XRD, Fourier-transform infrared spectroscopy (FTIR-ATR and colorimetric measurements were used in performing the study

    Seasonal influenza, causing complications, hospitalizations and deaths, generates a serious socio-economic burden, especially among elderly and high-risk subjects, as well as among adult individuals. Despite the availability and active free-of charge offer of influenza vaccines, vaccine coverage rates remain low and far from the target established by the Ministry of Health. Notwithstanding their effectiveness, vaccines are victims of prejudices and false myths, that contribute to the increasing phenomenon of vaccine hesitancy and loss of confidence. Media and, in particular, new media and information and communication technologies (ICTs) play a major role in disseminating health-related information. They are extremely promising devices for delivering health education and promoting disease prevention, including immunization. However, they can also have a negative impact on population's health attitudes and behaviors when channeling wrong, misleading information. During the 2014/2015 influenza vaccination campaign, the report of four deaths allegedly caused by administration of an adjuvanted influenza vaccine, Fluad - the so-called "Fluad case" - received an important media coverage, which contributed to the failure of the vaccination campaign, dramatically reducing the influenza vaccine uptake. In the extant literature, there is a dearth of information concerning the effect of the "Fluad case". The current study aims at quantifying the impact of the "Fluad effect" at the level of the Local Health Unit 3 (LHU3) ASL3 Genovese, Genoa, Italy. Ethical implications for health-care workers and health communication practitioners are also envisaged.

Pre-admission academic and socio-demographic data and undergraduate course marks were obtained. T-test and hierarchical multiple linear regression analyses were undertaken to identify independent predictors of five course outcomes at different stages throughout the course. There was no evidence that the choice of science or non-science as the third or fourth A-level subject had any influence on course performance. Demographic variables (age group, sex, and fee status) had some predictive value but ethnicity did not. Pre-clinical course performance was the strongest predictor in the clinical phases (pre-clinical Themes A&B (knowledge) predicted Clinical Knowledge, p A-level requirements should specify the choice of third or fourth subject.

    With the growth of online astronomy courses, it has become necessary to design different strategies for students to engage meaningfully with astronomy content. In contrast to some of the previously designed “cookbook”-style lab exercises, the strategy of these Infiniscope activities is to provide an experience where the students explore and discover the content for themselves. The Infiniscope project was created by ASU’s School of Earth and Space Exploration and NASA’s Science Mission Directorate as part of the NASA Exploration Connection project. As part of this project, online activities on topics such as asteroids and Kuiper Belt objects, eclipses, and Kepler’s Laws were designed and created for middle school (grades 6-8) and informal education settings. This poster discusses adapting these activities to the undergraduate non-science major setting. In fall 2017, the Infiniscope activities, such as Small Worlds and Kepler’s Laws, will be incorporated into an Arizona State University online astronomy course, AST 113, which is the laboratory component for the Introduction to Solar System Astronomy course sequence. This course typically enrolls about 800-900 students per semester with a combination of students who are online only as well as those who also take in person classes. In this type of class, we cannot have any in-person required sessions and all content must be delivered online asynchronously. The use of the Infiniscope exploratory exercises will provide students with the ability to use NASA data in a hands-on manner to discover the solar system for themselves.

    We present an approach to the canonical quantization of systems with equations of motion that are historically called non-Lagrangian equations. Our viewpoint of this problem is the following: despite the fact that a set of differential equations cannot be directly identified with a set of Euler-Lagrange equations, one can reformulate such a set in an equivalent first-order form that can always be treated as the Euler-Lagrange equations of a certain action. We construct such an action explicitly. It turns out that in the general case the hamiltonization and canonical quantization of such an action are non-trivial problems, since the theory involves time-dependent constraints. We adopt the general approach of hamiltonization and canonical quantization for such theories as described in D.M. Gitman, I.V. Tyutin, Quantization of Fields with Constraints (Springer, Berlin, 1990). to the case under consideration. There exists an ambiguity (that cannot be reduced to the addition of a total time derivative) in associating a Lagrange function with a given set of equations. We present a complete description of this ambiguity. The proposed scheme is applied to the quantization of a general quadratic theory. In addition, we consider the quantization of a damped oscillator and of a radiating point-like charge. (orig.)

    The formation of secondary ultrasonic echoes is discussed for a particularly simple testing situation. This discussion is based upon the intuitive visualization of elastic wave propagation as obtained with the numerical EFIT-Code (Elastodynamic Finite Integration Technique). The resulting travel times for the econdary echoes contain well-defined limits as they originate from the simple model of grazing incidence plane longitudinal wave mode conversion. (orig.) [de

  18. On the so called rogue waves in nonlinear Schrodinger equations

    Full Text Available The mechanism of a rogue water wave is still unknown. One popular conjecture is that the Peregrine wave solution of the nonlinear Schrodinger equation (NLS provides a mechanism. A Peregrine wave solution can be obtained by taking the infinite spatial period limit to the homoclinic solutions. In this article, from the perspective of the phase space structure of these homoclinic orbits in the infinite dimensional phase space where the NLS defines a dynamical system, we examine the observability of these homoclinic orbits (and their approximations. Our conclusion is that these approximate homoclinic orbits are the most observable solutions, and they should correspond to the most common deep ocean waves rather than the rare rogue waves. We also discuss other possibilities for the mechanism of a rogue wave: rough dependence on initial data or finite time blow up.

    Brust, Gregory John

    This study was designed to discover if there is a difference in the scientific attitudes and process skills between a group of students who were instructed with Living in a Material World and groups of students in non-science majors sections of introductory biology, chemistry, and geology courses at the University of Southern Mississippi (USM). Each of the four courses utilized different instructional techniques. Students' scientific attitudes were measured with the Scientific Attitudes Inventory (SAI II) and their knowledge of science process skills were measured with the Test of Integrated Process Skills (TIPS II). The Group Assessment of Logical Thinking (GALT) was also administered to determine if the cognitive levels of students are comparable. A series of four questionnaires called Qualitative Course Assessments (QCA) were also administered to students in the experimental course to evaluate subtle changes in their understanding of the nature and processes of science and attitudes towards science. Student responses to the QCA questionnaires were triangulated with results of the qualitative instruments, and students' work on the final project. Results of the GALT found a significant difference in the cognitive levels of students in the experimental course (PSC 190) and in one of the control group, the introductory biology (BSC 107). Results of the SAI II and the TIPS II found no significant difference between the experimental group and the control groups. Qualitative analyses of students' responses to selected questions from the TIPS II, selected items on the SAI II, QCA questionnaires, and Materials that Fly project reports demonstrate an improvement in the understanding of the nature and processes of science and a change to positive attitude toward science of students in the experimental group. Students indicated that hands-on, inquiry-based labs and performance assessment were the most effective methods for their learning. These results indicate that science

    How much did Seurat know about the physics, physiology, and perceptual science of color mixing when he began his experiments in pointillism? Did Vermeer have a camera obscura built into his studio to create the perfect perspective and luminous effects of his canvases? Early in the 20th century, consequences of the idea that "no single reference point is to be preferred above any other" were worked out in physics by Einstein (special and general relativity), in art by Picasso (early cubism), and in music by Schoenberg (12-tone compositions); did this same paradigm-shifting concept arise, in three disparate fields, merely by coincidence? We are developing a new course, aimed primarily at non-science majors, that addresses questions like these through a combination of hands-on experiments on the physics of light, investigations in visual perception, empirical tests of various drawing and painting techniques, and field trips to nearby museums. We will show a few examples of the kinds of art/science intersections our students will be exploring, and present a working outline for the course.

    Hundley, Stacey A.

    In recent years there has been a national call for reform in undergraduate science education. The goal of this reform movement in science education is to develop ways to improve undergraduate student learning with an emphasis on developing more effective teaching practices. Introductory science courses at the college level are generally taught using a traditional lecture format. Recent studies have shown incorporating active learning strategies within the traditional lecture classroom has positive effects on student outcomes. This study focuses on incorporating interactive teaching methods into the traditional lecture classroom to enhance student learning for non-science majors enrolled in introductory geology courses at a private university. Students' experience and instructional preferences regarding introductory geology courses were identified from survey data analysis. The information gained from responses to the questionnaire was utilized to develop an interactive lecture introductory geology course for non-science majors. Student outcomes were examined in introductory geology courses based on two teaching methods: interactive lecture and traditional lecture. There were no significant statistical differences between the groups based on the student outcomes and teaching methods. Incorporating interactive lecture methods did not statistically improve student outcomes when compared to traditional lecture teaching methods. However, the responses to the survey revealed students have a preference for introductory geology courses taught with lecture and instructor-led discussions and students prefer to work independently or in small groups. The results of this study are useful to individuals who teach introductory geology courses and individuals who teach introductory science courses for non-science majors at the college level.

  3. Using a dynamic, introductory-level volcanoes class as a means to introduce non-science majors to the geosciences

    2012-12-01

    At the University of California, San Diego, I teach a quarter-long, introductory Earth Science class titled "Volcanoes," which is, in essence, a functional class in volcanology designed specifically for non-majors. This large-format (enrollment ~ 85), lecture-based class provides students from an assortment of backgrounds an opportunity to acquire much-needed (and sometimes dreaded) area credits in science, while also serving as an introduction to the Earth Science major at UCSD (offered through Scripps Institution of Oceanography). The overall goal of the course is to provide students with a stimulating and exciting general science option that, using an inherently interesting topic, introduces them to the fundamentals of geoscience. A secondary goal is to promote general science and geoscience literacy among the general population of UCSD. Student evaluations of this course unequivocally indicate a high degree of learning and interest in the material. The majority of students in the class (>80%) are non-science majors and very few students (degree-seeking students. In addition, only a handful of students have typically had any form of geology class beyond high school level Earth Science. Consequently, there are challenges associated with teaching the class. Perhaps most significantly, students have very little background—background that is necessary for understanding the processes involved in volcanic eruptions. Second, many non-science students have built-in anxieties with respect to math and science, anxieties that must be considered when designing curriculum and syllabi. It is essential to provide the right balance of technical information while remaining in touch with the audience. My approach to the class involves a dynamic lecture format that incorporates a wide array of multimedia, analogue demonstrations of volcanic processes, and small-group discussions of topics and concepts. In addition to teaching about volcanoes—a fascinating subject in and of

    Non-science majors often misunderstand the process of science, potentially leading to a fear or mistrust of scientific inquiry and current scientific theory. Citizen science projects are a critical means of reaching this audience, as many will only take a limited number of science courses during their undergraduate careers. For the past three years, our freshman Earth Science students have participated in both Globe at Night and the Great Worldwide Star Count, citizen science programs that encourage simple astronomical observations which can be compiled globally to investigate a number of issues. Our focus has been introducing students to the effect of light pollution on observational astronomy in an effort to highlight the effect of increasing urbanization in the U.S. on amateur astronomy. These programs, although focused on astronomy, often awaken natural curiosity about the Earth and man's effect on the natural world, a concept that can easily be translated to other areas of Earth science. Challenges encountered include content specific issues, such as misinterpreting the location or magnitude of the constellation being observed, as well as student disinterest or apathy if the project is not seen as being vital to their performance in the course. This presentation reports on lessons learned in the past three years, and offers suggestions for engaging these students more fully in future projects.

    Today's science classrooms are addressing the need for non-scientists to become scientifically literate. A key aspect includes the recognition of science as a process for discovery. This process relies upon interdisciplinary collaboration. We designed a semester-long collaborative exercise that allows science majors taking a general microbiology course and non-science majors taking an introductory environmental science course to experience collaboration in science by combining their differing skill sets to identify microorganisms enriched in Winogradsky columns. These columns are self-sufficient ecosystems that allow researchers to study bacterial populations under specified environmental conditions. Non-science majors identified phototrophic bacteria enriched in the column by analyzing the signature chlorophyll absorption spectra whereas science majors used 16S rRNA gene sequencing to identify the general bacterial diversity. Students then compiled their results and worked together to generate lab reports with their final conclusions identifying the microorganisms present in their column. Surveys and lab reports were utilized to evaluate the learning objectives of this activity. In pre-surveys, nonmajors' and majors' answers diverged considerably, with majors providing responses that were more accurate and more in line with the working definition of collaboration. In post-surveys, the answers between majors and nonmajors converged, with both groups providing accurate responses. Lab reports showed that students were able to successfully identify bacteria present in the columns. These results demonstrate that laboratory exercises designed to group students across disciplinary lines can be an important tool in promoting science education across disciplines.

    We developed the palm size (optical unit: 73[mm]×102[mm]×66[mm]) and light weight (total weight with electrical controller: 1.7[kg]) middle infrared (wavelength range: 8[μm]-14[μm]) 2-dimensional spectroscopy for UAV (Unmanned Air Vehicle) like drone. And we successfully demonstrated the flights with the developed hyperspectral camera mounted on the multi-copter so-called drone in 15/Sep./2015 at Kagawa prefecture in Japan. We had proposed 2 dimensional imaging type Fourier spectroscopy that was the near-common path temporal phase-shift interferometer. We install the variable phase shifter onto optical Fourier transform plane of infinity corrected imaging optical systems. The variable phase shifter was configured with a movable mirror and a fixed mirror. The movable mirror was actuated by the impact drive piezo-electric device (stroke: 4.5[mm], resolution: 0.01[μm], maker: Technohands Co.,Ltd., type:XDT50-45, price: around 1,000USD). We realized the wavefront division type and near common path interferometry that has strong robustness against mechanical vibrations. Without anti-mechanical vibration systems, the palm-size Fourier spectroscopy was realized. And we were able to utilize the small and low-cost middle infrared camera that was the micro borometer array (un-cooled VOxMicroborometer, pixel array: 336×256, pixel pitch: 17[μm], frame rate 60[Hz], maker: FLIR, type: Quark 336, price: around 5,000USD). And this apparatus was able to be operated by single board computer (Raspberry Pi.). Thus, total cost was less than 10,000 USD. We joined with KAMOME-PJ (Kanagawa Advanced MOdule for Material Evaluation Project) with DRONE FACTORY Corp., KUUSATSU Corp., Fuji Imvac Inc. And we successfully obtained the middle infrared spectroscopic imaging with multi-copter drone.

  9. Understandings of Nature of Science and Multiple Perspective Evaluation of Science News by Non-science Majors

    Understandings of nature of science (NOS) are a core component of scientific literacy, and a scientifically literate populace is expected to be able to critically evaluate science in the media. While evidence has remained inconclusive on whether better NOS understandings will lead to critical evaluation of science in the media, this study aimed at examining the correlation therein. Thirty-eight non-science majors, enrolled in a science course for non-specialists held in a local community college, evaluated three health news articles by rating the extent to which they agreed with the reported claims and providing as many justifications as possible. The majority of the participants were able to evaluate and justify their viewpoint from multiple perspectives. Students' evaluation was compared with their NOS conceptions, including the social and cultural embedded NOS, the tentative NOS, the peer review process and the community of practice. Results indicated that participants' understanding of the tentative NOS was significantly correlated with multiple perspective evaluation of science news reports of socioscientific nature (r = 0.434, p media of socioscientific nature. However, the null result for other target NOS aspects in this study suggested a lack of evidence to assume that understanding the social dimensions of science would have significant influence on the evaluation of science in the media. Future research on identifying the reasons for why and why not NOS understandings are applied in the evaluation will move this field forward.

  10. Social justice pedagogies and scientific knowledge: Remaking citizenship in the non-science classroom

    Science.gov (United States)

    Lehr, Jane L.

    This dissertation contributes to efforts to rethink the meanings of democracy, scientific literacy, and non-scientist citizenship in the United States. Beginning with questions that emerged from action research and exploring the socio-political forces that shape educational practices, it shows why non-science educators who teach for social justice must first recognize formal science education as a primary site of training for (future) non-scientist citizens and then prepare to intervene in the dominant model of scientifically literate citizenship offered by formal science education. This model of citizenship defines (and limits) appropriate behavior for non-scientist citizens as acquiescing to the authority of science and the state by actively demarcating science from non-science, experts from non-experts, and the rational from the irrational. To question scientific authority is to be scientifically illiterate. This vision of 'acquiescent democracy' seeks to end challenges to the authority of science and the state by ensuring that scientific knowledge is privileged in all personal and public decision-making practices, producing a situation in which it becomes natural for non-scientist citizens to enroll scientific knowledge to naturalize oppression within our schools and society. It suggests that feminist and equity-oriented science educators, by themselves, are unable or unwilling to challenge certain assumptions in the dominant model of scientifically literate citizenship. Therefore, it is the responsibility of non-science educators who teach for social justice to articulate oppositional models of non-scientist citizenship and democracy in their classrooms and to challenge the naturalized authority of scientific knowledge in all aspects of our lives. It demonstrates how research in the field of Science & Technology Studies can serve as one resource in our efforts to intervene in the dominant model of scientifically literate citizenship and to support a model of

    Lyons, Daniel J.

    This study explored the impact of a novel inquiry-based astronomy laboratory curriculum designed using the Backwards Faded Scaffolding inquiry teaching framework on non-science majoring undergraduate students' views of the nature of scientific inquiry (NOSI). The study focused on two aspects of NOSI: The Distinction between Data and Evidence (DvE), and The Multiple Methods of Science (MMS). Participants were 220 predominately non-science majoring undergraduate students at a small, doctoral granting, research-extensive university in the Rocky Mountain region of the United States. The student participants were enrolled in an introductory astronomy survey course with an associated laboratory section and were selected in two samples over consecutive fall and spring semesters. The participants also included four of the graduate student instructors who taught the laboratory courses using the intervention curriculum. In the first stage, student participant views of NOSI were measured using the VOSI-4 research instrument before and after the intervention curriculum was administered. The responses were quantified, and the distributions of pre and posttest scores of both samples were separately analyzed to determine if there was a significant improvement in understanding of either of the two aspects of NOSI. The results from both samples were compared to evaluate the consistency of the results. In the second stage, the quantitative results were used to strategically design a qualitative investigation, in which the four lab instructors were interviewed about their observations of how the student participants interacted with the intervention curriculum as compared to traditional lab activities, as well as their suggestions as to how the curriculum may or may not have contributed to the results of the first stage. These interviews were summarized and analyzed for common themes as to how the intervention curriculum influenced the students' understandings of the two aspect of

    Although inquiry-based/problem-based methods have been successfully incorporated in undergraduate lecture classes, a survey of commonly used laboratory manuals indicates that few non-major geoscience laboratory classes use these strategies. The Department of Geology and Environmental Geosciences faculty members have developed a successful introductory Environmental Geology Laboratory course for undergraduate non-majors that challenges traditional teaching methodology as illustrated in most laboratory manuals. The Environmental Geology lab activities employ active learning methods to engage and challenge students. Crucial to establishing an open learning environment is capturing the attention of non-science majors from the moment they enter the classroom. We use catastrophic ‘gloom and doom’ current events to pique the imagination with images, news stories, and videos. Once our students are hooked, we can further the learning process with use of other teaching methods: an inquiry-based approach that requires students take control of their own learning, a cooperative learning approach that requires the participation of all team members in peer learning, and a problem/case study learning approach that primarily relies on activities distilled from current events. The final outcome is focused on creating innovative methods to communicate the findings to the general public. With the general public being the audience for their communiqué, students are less intimated, more focused, and more involved in solving the problem. During lab sessions, teams of students actively engage in mastering course content and develop essential communication skills while exploring real-world scenarios. These activities allow students to use scientific reasoning and concepts to develop solutions for scenarios such as volcanic eruptions, coastal erosion/sea level rise, flooding or landslide hazards, and then creatively communicate their solutions to the public. For example, during a two

    Dutra, Andrew Martin

    The purpose of this study was to determine the relationship of specific attributes of college students to their academic achievement at an independent university in central Florida. Academic achievement was measured as the numeric score on the final exam in a survey-of-science course (EDS 1032) required for non-science majors. Attribute sets included personological, affective, and fitness variables. A hypothesized diagram of the direct and indirect effects among these attributes relative to academic achievement was developed and tested using data collected Spring 2014 from 168 students in four sections of EDS 1032 at Florida Institute of Technology. Multiple regression results revealed that 19% of the variance in a students' academic achievement was due to the influence of these three sets of research factors; this was found to be statistically significant. The results of mediation analyses also indicated that three variables had significant direct effects on academic achievement, namely gender, number of academic credits, and sports motivation. In addition, gender had a significant indirect effect on academic achievement via stress, and the number of academic credits had a significant indirect effect on academic achievement via sports motivation. These findings indicated that female students scored roughly six points higher than male students on this final exam. Also, gender's influence on academic achievement was partially attributable to the student's level of stress (e.g., male students with high levels of stress had lower grades on this final exam than female students with the same level of stress). In addition, it was found that students taking more academic credits were likely to score higher on this final exam than those students taking fewer credits. Further, as students' level of sports amotivation increased, the strength of the relationship between the number of student academic credits and academic achievement decreased. These results support Self

    2008-12-01

    In recent years several geoscience communities have been developing ocean, climate, atmosphere and earth science literacy frameworks as enhancements to the National Science Education Standards content standards. Like the older content standards these new geoscience literacy frameworks have focused on K-12 education although they are also intended for informal education and general public audiences. These geoscience literacy frameworks potentially provide a more integrated and less abstract approach to science literacy that may be more suitable for non-science major students that are not pursuing careers in science research or education. They provide a natural link to contemporary environmental issues - e.g., climate change, resource depletion, species and habitat loss, natural hazards, pollution, development of renewable energy, material recycling. The College of Exploration is an education research non-profit that has provided process and technical support for the development of most of these geoscience literacy frameworks. It has a unique perspective on their development. In the last ten years it has also gained considerable national and international expertise in facilitating web-based workshops that support in-depth conversations among educators and working scientists/researchers on important science topics. These workshops have been of enormous value to educators working in K-12, 4-year institutions and community colleges. How can these geoscience literacy frameworks promote more collaborative inquiry-based learning that enhances the appreciation of scientific thinking by non-majors? How can web- and mobile-based education technologies transform the undergraduate non-major survey course into a place where learners begin their passion for science literacy rather than end it? How do we assess science literacy in students and citizens?

    être réexaminée, car il semble probable que nous ayons affaire à une œuvre littéraire manquée.This article calls into question the value and reliability of the contents of P.Oxy. X 1241, the so-called list of Alexandria Librarians. Rather than treating the list of grammarians at col. i.5-ii.30 by itself, as scholars have done ever since the papyrus was published, this paper considers the document in its entirety. This closer reading of P.Oxy. X 1241 demonstrates that there is clear thematic continuity between the list of grammarians and the military catalogues that follow which has never been observed before, precisely because the two parts have always been treated separately. Challenges to three crucial assumptions of the original editors, B. P. Grenfell and A. S. Hunt emerge: (1 Is the list at col. i.5-ii.30 in fact a list of the heads of the Alexandrian library? (2 Is the work a copy or compilation of some earlier scholarly piece that dates back to the Hellenistic period, and not a product of a circa second century CE scholar/grammarian? (3 Do the contents of the papyrus reflect the work of a competent scholar/grammarian who was well enough informed about the chronology of the Ptolemaic period to produce an historically accurate account of the succession of individuals connected to the Ptolemaic court and the Alexandrian Library? While it is true to say that in its content and use of learned citations P.Oxy. X 1241 shares many similarities with Hellenistic and Imperial prose catalogues, the strategies of learned discourse deployed by the author in the military catalogue do not conform to the norms of reliable scholarly examples. Accordingly, the value of the text as documentary evidence of the history of the Alexandrian library needs to be reconsidered as it seems likely that we are dealing with a failed literary work.Questo articolo mette in dubbio il valore e l’attendibilità del contenuto di P.Oxy.

    Medical schools have tended to admit students with strong backgrounds in the biomedical sciences. Previous studies have shown that those with backgrounds in the social sciences can be as successful in medical school as those with science backgrounds. However, the experience of being a 'non-science' student over time has not been well described. A mixed-methods study was developed and run with the aim of elucidating the personal experiences of science and non-science students at our institution. Data were generated from a student survey that focused on participants' self-identification as science or non-science students, and on their sense of preparedness and stress, and from a series of student focus groups exploring participants' experiences of science and non-science issues in all aspects of their training. Descriptive statistics were generated for structured survey data. Focus group data and unstructured survey data were analysed to identify common themes. End-of-module and end-of-year examination data for the four class cohorts in the programme were also analysed to compare science and non-science student performance over time. There were clear differences between the experiences and performance of science and non-science students. We found dichotomies in students' self-reported sense of preparedness and stress levels, and marked differences in their examination performance, which diminished over time to converge around the third year of their studies. Combining science and non-science students in the same class affected the students to different extents and in different ways. The potential disruption of mixing science and non-science students diminished as their levels of performance converged. The psychosocial stress experienced by non-science students and the challenges it posed, in both their academic and their personal lives, have implications for how such students should be supported, and how curricula can be configured to afford quality learning for all

    Helping students develop criteria for judgment and apply examination skills is essential for promoting scientific literacy. With the increasing availability of the Internet, it is even more essential that students learn how to evaluate the science they gather from online resources. This is particularly true because publishing information on the web is not restricted to experts, and content quality can vary greatly across websites. The responsibility of evaluating websites falls upon the user. Little research has examined undergraduates' evaluation of web sites in science classes. The purpose of this study was to investigate on which websites college students selected and how they evaluated the websites used when developing individual positions about stem-cell research. We used a qualitative approach in search of patterns in undergraduates' website selection and evaluation criteria. We found that students used a variety of web resources from eleven types of websites to complete their independent research report. Students also used eleven evaluation criteria to evaluate these sources, some useful (e.g., credibility) and some not useful (e.g., readability). We found that university students struggled with critically evaluating online resources. Undergraduates need prompts to learn how to critically evaluate the science content provided within websites. This type of scaffold can facilitate useful evaluation and promote critical thinking required for becoming scientifically literate.

  5. Rhizophores in Rhizophora mangle L: an alternative interpretation of so-called ''aerial roots''

    Directory of Open Access Journals (Sweden)

    Menezes Nanuza L. de

    2006-01-01

    Full Text Available Rhizophora mangle L., one of the most common mangrove species, has an aerial structure system that gives it stability in permanently swampy soils. In fact, these structures, known as "aerial roots" or "stilt roots", have proven to be peculiar branches with positive geotropism, which form a large number of roots when in contact with swampy soils. These organs have a sympodial branching system, wide pith, slightly thickened cortex, collateral vascular bundles, polyarch stele and endarch protoxylem, as in the stem, and a periderm produced by a phellogen at the apex similar to a root cap. They also have the same type of trichosclereid that occurs in the stem, with negative geotropism, unlike true Rhizophora roots, which do not form trichosclereids at all. On the other hand, these branches do not form leaves and in this respect they are similar to roots. These peculiar branches are rhizophores or special root-bearing branches, analogous to those found in Lepidodendrales and other Carboniferous tree ferns that grew in swampy soils.

  6. Nuclear power industry from the viewpoint of entropy so-called, 3

    In Japan, the nuclear power industry tends to be grouped, which is understandable because of its nature as the unification of various technology aspects. The grouped operation implies the state in order (low entropy). If this grouped operation (low entropy) is in a state of low economic value (high entropy), in order to raise the economic value (low entropy), the tendency will be to weaken the grouping (high entropy). For raising the low economic value (high entropy) to a higher state (low entropy), other energy or value must be consumed. In the problematic situation when the economic value is also high for manufacturing and construction enterprises (low entropy), the leadership by the electric power enterprises is strongly desired.

    2012-07-01

    The UK Food Standards Agency and its counterparts in other countries have warned consumers not to eat hijiki (Sargassum fusiforme; synonym Hizikia fusiformis), a Sargasso seaweed, because it contains large amounts of inorganic arsenic. We investigated dietary exposure of hijiki in weaning male F344/N rats fed an AIN-93G diet supplemented with 3% (w/w) hijiki powder for 7 weeks, compared with those fed only an AIN-93G diet. Body weight, body temperature, blood and tissue arsenic concentrations, plasma biochemistry and hematological parameters were measured. We found that feeding rats a 3% hijiki diet led to a marked accumulation of arsenic in blood and tissues, and evoked a high body temperature and abnormal blood biochemistry including elevated plasma alkaline phosphatase activity and inorganic phosphorus, consistent with arsenic poisoning. These findings should prompt further investigations to identify the health hazards related to consumption of hijiki and related Sargassum species in humans. Copyright © 2012 Elsevier Inc.

  12. [Regarding respiration and the so-called "animal heat." An historical sketch].

    Science.gov (United States)

    de Micheli, A

    2001-01-01

    According to Aristotle and Galen, the essential function of the respiration phenomenon was to cool the blood. Towards the middle of the XVI Century, Miguel Servet suggested, in his treatise Christianismi restitutio..., that the inspired air could have other functions besides cooling the blood. Later, Joseph Black thought that respiration was a combustion. In the light of the advances in chemistry achieved in the XVII Century, the English scientist Adair Crawford and the French chemist Antoine-Laurent Lavoisier conceived, in the second half of that century, the first general and quantitative theories on the origin of animal heat. Both these authors had the conviction that the "inflammable element", which will be called oxygen, was not formed in the pulmonary territory, but could be absorbed by the blood. Oxygen, foreseen by Mayow at the end of XVII Century, was discovered by Joseph Priestley in 1774. Lavoisier gave the name of oxygen to this gas and firmly established that the respiration phenomenon consists essentially in a process of combustion. The mathematician Joseph-Louis Lagrange, native of Turin, suggested that animal heat originates in all breathing tissues. This phenomenon was verified and described in detail by the biologist Lazzaro Spallanzani, professor at the University of Pavia. Dissemination, in the scientific world, of the new chemical nomenclature and of the respiratory theory, closely related to it, was based fundamentally on the works "Méthode de nomenclature chimique..." (1787) and "Traité élémentaire de chimie..." (1789). During the XIX Century, studies on the phenomenon of animal respiration continued and fundamental discoveries in this subject were attained, such as conversion of hemoglobin to oxyhemoglobin once oxygen had been fixed. Now it is possible to study the regulating mechanisms of the energetic metabolism of the myocardium in vivo, which allows decisive interventions in certain cardiopathies, such as in acute ischemic cardiopathy.

    The present work contains a comparison of findings on 50 patients with progressive and resolving infantile scoliosis, as far as they are important for prognostication, with the investigations of Metha and other authors. These were the data obtained: 1. Among the 46 cases of 'resolving scoliosis' investigated, 93 per cent showed a difference of the rib-vertebra angles of below 20 degrees. 2. In the four patients with 'progressive scoliosis', a difference of the rib-vertebra angles below the 20-degree limit was seen which is said by Metha to be of unfavourable prognostication. 3. In all of the progressive cases, the rib head on the concave side was found to project into the shadow of the vertex vertebra, which is considered by Metha to be an unfavourable prognostical sign. However, the same position was also seen in 7 out of 46 resolving scolioses. The entire values collected from the 50 patients confirm the characteristics of the disease. (orig./MG) [de

    Carcinoma in the ''empty breast'' in our experience is so common that we doubt Wolfe's conclusions in his classification of parenchymal patterns. Amongst patients over 60 years, almost 70% of carcinomas were situated in an ''empty'' parenchyma and they did not develop in a parechymal group above P1. Mammographically, the ''empty breast'' is the structureless fatty breast of older women after the menopause. Some authors believe that there is a lower incidence of carcinomas in this type of breast than in other types of parenchyma, such as those showing mastopathies. Our experience concerning carcinomas in involuted breasts is described. (orig.) [de

    1981-01-01

    The fogging effect, whereby initially hypodense infarcts become isodense during the second and third week after the onset of stroke, was investigated in a prospective and consecutive series comprising 50 cases with completed stroke. CT scans were performed approximately 3 days, 10 days and 6 months after stroke. The fogging effect was found in 54% of cases. The hypodense areas reappeared on all scans at 6 months. Cerebral infarcts therefore may be overlooked or grossly underestimated if the scan is performed during the second and third week after stroke. (orig.)

  20. [Diagnosis of depressive disorder and so-called exhaustion depression. Self-esteem--a central concept].

    Science.gov (United States)

    Beck-Friis, Johan

    2002-02-07

    Depressive disorders can be recognized by the loss of self-esteem; this contrasts with mourning and neurasthenic reactions, in which self-esteem remains intact. Just as depression can result from the gradual reduction and eventual loss of self-esteem, mourning and neurasthenic reactions can evolve into true depressive states. "Exhaustion depression", a new diagnostic category connected to "burnout" situations, should be applied only when criteria for depressive disorder are fulfilled, including loss of self-esteem. When these criteria are lacking we should refer only to an exhaustion state provoked by stress. Neurotic mechanisms may represent a special class of relevant stress factors, but are not seen in manifest neurasthenic reactions and exhaustion depression.

  1. Do Hospitals Owe A So-Called 'Non-Delegable' Duty of Care to their Patients?

    Science.gov (United States)

    Beuermann, Christine

    2018-02-01

    It is not uncommon for the duty of care owed by a hospital to its patients to be described as 'non-delegable'. Use of this label suggests that a hospital may be held strictly liable to a patient for the wrongdoing of a third party beyond the circumstances in which vicarious liability might be imposed. To date, no higher court has used the label to impose such liability. Notwithstanding, it was assumed by Lord Sumption in Woodland v Swimming Teachers Association that the duty of care owed by a hospital to a patient could be so described when formulating his test for determining the existence of a 'non-delegable duty of care'. This article challenges that assumption and, in turn, the veracity of the test devised by Lord Sumption.

    Full Text Available "What does the term "terrorism" mean." Why does the term “terrorism” often identified as Islam? "If terrorism is an ism that affects "terror" that it generates, while Islam which literally means "peace", then the two terms certainly mismatch! Such question and statement show Muslims’ concern over frequent phenomena of "terrorism" using Islamic religious symbols. The research undertaken proved that there are three explanations. First, a close tripartite network connection between “terrorism experts” and the circles of power policy holders who are also supported by senior journalists in the international media influence. Second, a long tradition of Orientalist studies in the study of the Middle East region and the study of religion in the Arab culture. Figures such as Bernard Lewis, Noah Feldman, Raphael Patai and other Middle East experts often sit with other experts in the field of terrorism (the first factor and become main advisors and expert staff for the US government in the formulation of action to counter terror. It was the catalyst for the transmission of viewpoint which then decorated orientalist discourse of Islamic terrorism in the process of political policies. Third, a lot of Islamic terrorism discourse refers to the long tradition of cultural stereotypes and biased representations of the media that often portray Islam and Muslims as ‘the enemy’. The reason is that it reflects the perspective of socio-Western culture that fears and worries the other oriental parties which has been stereotyped since the imperial era. Many also argue that the dichotomy of the orientalist views are deliberately preserved as a form of new style imperialism

  4. Using Internet-Based Robotic Telescopes to Engage Non-Science Majors in Astronomical Observation

    Berryhill, K. J.; Coble, K.; Slater, T. F.; McLin, K. M.; Cominsky, L. R.

    2013-12-01

    Responding to national science education reform documents calling for students to have more opportunities for authentic research experiences, several national projects have developed online telescope networks to provide students with Internet-access to research grade telescopes. The nature of astronomical observation (e.g., remote sites, expensive equipment, and odd hours) has been a barrier in the past. Internet-based robotic telescopes allow scientists to conduct observing sessions on research-grade telescopes half a world away. The same technology can now be harnessed by STEM educators to engage students and reinforce what is being taught in the classroom, as seen in some early research in elementary schools (McKinnon and Mainwaring 2000 and McKinnon and Geissinger 2002), middle/high schools (Sadler et al. 2001, 2007 and Gehret et al. 2005) and undergraduate programs (e.g., McLin et al. 2009). This project looks at the educational value of using Internet-based robotic telescopes in a general education introductory astronomy course at the undergraduate level. Students at a minority-serving institution in the midwestern United States conducted observational programs using the Global Telescope Network (GTN). The project consisted of the use of planetarium software to determine object visibility, observing proposals (with abstract, background, goals, and dissemination sections), peer review (including written reviews and panel discussion according to NSF intellectual merit and broader impacts criteria), and classroom presentations showing the results of the observation. The GTN is a network of small telescopes funded by the Fermi mission to support the science of high energy astrophysics. It is managed by the NASA E/PO Group at Sonoma State University and is controlled using SkyNet. Data includes course artifacts (proposals, reviews, panel summaries, presentations, and student reflections) for six semesters plus student interviews. Using a grounded theory approach

    2016-06-01

    A first order understanding of planet formation and the scientific concepts therein is critical in order for undergraduate students to understand our place in the Universe. Furthermore, planet formation integrates the topics of gravity, angular momentum, migration, and condensation in a “story-book” fashion where students can apply these concepts to a specific event. We collected syllabi and course topics from over 30 undergraduate general-education astrobiology courses from around the globe in order to determine the extent to which professors address planet formation. Additionally, we were looking to see if faculty had developed specific or original pedagogy to teach this topic. We find on average, instructors spend ½ of a lecture discussing planet formation or they leave it out all together. In the classes where planet formation is taught more extensively, instructors use PowerPoint slides or occasional videos to teach the topic. We aim to develop new pedagogy that will allow us to better determine learning gains and student understanding of this critical topic. If students in an astrobiology class are unable to understand how our own Solar System forms, it is significantly more challenging to make parallels (or find differences) between our home in the Universe and extrasolar planetary systems.

    Pilachowski, Catherine A.; van Zee, Liese

    2017-01-01

    The Art of Astronomy is a new general education course developed at Indiana University. The topic appeals to a broad range of undergraduates and the course gives students the tools to understand and appreciate astronomical images in a new way. The course explores the science of imaging the universe and the technology that makes the images possible. Topics include the night sky, telescopes and cameras, light and color, and the science behind the images. Coloring the Universe: An Insider's Look at Making Spectacular Images of Space" by T. A. Rector, K. Arcand, and M. Watzke serves as the basic text for the course, supplemented by readings from the web. Through the course, students participate in exploration activities designed to help them first to understand astronomy images, and then to create them. Learning goals include an understanding of scientific inquiry, an understanding of the basics of imaging science as applied in astronomy, a knowledge of the electromagnetic spectrum and how observations at different wavelengths inform us about different environments in the universe, and an ability to interpret astronomical images to learn about the universe and to model and understand the physical world.

  12. Spatial abilities, Earth science conceptual understanding, and psychological gender of university non-science majors

    Science.gov (United States)

    Black, Alice A. (Jill)

    Research has shown the presence of many Earth science misconceptions and conceptual difficulties that may impede concept understanding, and has also identified a number of categories of spatial ability. Although spatial ability has been linked to high performance in science, some researchers believe it has been overlooked in traditional education. Evidence exists that spatial ability can be improved. This correlational study investigated the relationship among Earth science conceptual understanding, three types of spatial ability, and psychological gender, a self-classification that reflects socially-accepted personality and gender traits. A test of Earth science concept understanding, the Earth Science Concepts (ESC) test, was developed and field tested from 2001 to 2003 in 15 sections of university classes. Criterion validity was .60, significant at the .01 level. Spearman/Brown reliability was .74 and Kuder/Richardson reliability was .63. The Purdue Visualization of Rotations (PVOR) (mental rotation), the Group Embedded Figures Test (GEFT) (spatial perception), the Differential Aptitude Test: Space Relations (DAT) (spatial visualization), and the Bem Inventory (BI) (psychological gender) were administered to 97 non-major university students enrolled in undergraduate science classes. Spearman correlations revealed moderately significant correlations at the .01 level between ESC scores and each of the three spatial ability test scores. Stepwise regression analysis indicated that PVOR scores were the best predictor of ESC scores, and showed that spatial ability scores accounted for 27% of the total variation in ESC scores. Spatial test scores were moderately or weakly correlated with each other. No significant correlations were found among BI scores and other test scores. Scantron difficulty analysis of ESC items produced difficulty ratings ranging from 33.04 to 96.43, indicating the percentage of students who answered incorrectly. Mean score on the ESC was 34

    An important trend in the Vocational Education and Training (VET) system in the Netherlands is the design of continuous learning pathways enclosing more than one school type level. These continuous learning pathways are characterized by different design formats. In this study, the relations between these design formats and student performance and satisfaction were examined. Five coordinators and 161 students of five so-called Green Lycea (GL) in the life sciences domain, in which the elements...

    The whole process of a second case of chronic granulocytic leukemia in Nishiyama district where a very small amount of radiation existed for a long time was reported together with data measured by a human counter and the results of chromosomal analysis. No significantly high K or /sup 137/Cs values were measured by a human counter immediately after the onset. Chromosomal division aberration and chromosomal aberration, which seemed to be induced by radiation, also were not observed. However, granulocytic leukemia was diagnosed after chromosomal analysis of peripheral blood revealed Ph/sup 1/ chromosomes, white cell count increased, juvenile cells appeared, and basophil cells increased. Clinical features of typical chronic granulocytic leukemia in the exposed were observed during the chronic stage (7 years). In the acute stage, abnormal clones were discovered in all 16 chromosomes analyzed. Much karyotypic evolution identical to that in persons directly exposed to the A-bomb was also observed.

    Full Text Available Abstract Background Recently, the MRI finding of "Modic changes" has been identified as pathologic spinal condition that probably reflects a vertebral inflammatory process (VIP, which coincides with spinal pain in most. We hypothesized that heavy smoking in combination with macro- or repeated microtrauma could lead to VIP. The objectives were to investigate if combinations of self-reported heavy smoking, hard physical work, and overweight would be more strongly linked with VIP than with other spinal conditions, such as degenerated discs and non-specific low back pain (LBP. Methods Secondary analysis was made of a data base pertaining to a population-based cross-sectional study. A population-generated cohort of 412 40-yr old Danes provided questionnaire information on smoking, weight, height, type of work, and LBP. MRI was used to determine the presence/absence of disc degeneration and of VIP. Associations were tested between three explanatory variables (type of work, smoking, and body mass index and four outcome variables (LBP in the past year, more persistent LBP in the past year, disc degeneration, and VIP. Associations with these four outcome variables were studied for each single explanatory variable and for combinations of two at a time, and, finally, in a multivariable analysis including all three explanatory variables. Results There were no significant associations between the single explanatory variables and the two pain variables or with disc degeneration. However, VIP was found in 15% of non-smokers vs. 26% of heavy smokers. Similarly, VIP was noted in 11% of those in sedentary jobs vs. 31% of those with hard physical work. Further, the prevalence of VIP in those, who neither smoked heavily nor had a hard physical job was 13%, 25% in those who either smoked heavily or had a hard physical job, and 41% in those who both smoked heavily and worked hard. The odds ratio was 4.9 (1.6–13.0 for those who were both heavy smokers and had a hard physical job as compared to those who were classified as "neither". Similar but weaker findings were noted for the combination of overweight and hard physical work but not for the combination of smoking and overweight. Conclusion Hard physical work in combination with either heavy smoking or overweight is strongly associated with VIP. If this finding can be reproduced in other studies, it may have consequences in relation to both primary and secondary prevention of LBP, because blue collar workers, who are most likely to experience the consequences of LBP, also are those who are most likely to smoke.

    General characteristics of the multivariate statistical analysis (MSA) is given. Methodical premises and criteria for the selection of an adequate MSA method applicable to pathoanatomic investigations of the epidemiology of multicausal diseases are presented. The experience of using MSA with computors and standard computing programs in studies of coronary arteries aterosclerosis on the materials of 2060 autopsies is described. The combined use of 4 MSA methods: sequential, correlational, regressional, and discriminant permitted to quantitate the contribution of each of the 8 examined risk factors in the development of aterosclerosis. The most important factors were found to be the age, arterial hypertension, and heredity. Occupational hypodynamia and increased fatness were more important in men, whereas diabetes melitus--in women. The registration of this combination of risk factors by MSA methods provides for more reliable prognosis of the likelihood of coronary heart disease with a fatal outcome than prognosis of the degree of coronary aterosclerosis.

    The purpose of this study was to demonstrate the macroscopic and MRI anatomy of the fasciculus obliquus, otherwise known as the ligamentum glenohumerale spirale or spiral GHL of the anterior shoulder joint capsule. Conventional and MR arthrography (1.5-T device Somatom Symphony, Siemens with shoulder coil) images in standard planes were compared with gross anatomic dissection findings in six fresh shoulder specimens from three cadavers. The MR imaging protocol included T1, PD and DESS 3D WI sequences. The macroscopically recognisable band - the spiral GHL - was identified by anatomic dissection and MRI in all the specimens. It was best visualised by MR arthrography on axial and oblique sagittal planes (T1; PD WI) and appeared as a low signal intensity stripe within the superficial layer of the anterior joint capsule. The absence of the variable middle glenohumeral ligament did not influence the anatomic properties and the MR imaging of the spiral GHL. Diagnostic visualisation of the normal anatomic structures is a prerequisite to distinguish between normal and pathologic conditions. Anatomy of the spiral GHL can be used by radiologists for more detailed interpretation of the anterior shoulder joint capsule ligaments on MR images. (orig.)

    OBJECTIVE Diagnostic criteria for hippocampal malrotation (HIMAL) on brain MRI typically include a rounded hippocampus, vertical collateral sulcus, and architectural blurring. Relationship to epileptogenesis remains speculative, and usefulness for surgical guidance is unknown. The study was performed to determine the prevalence of hippocampal rotational anomalies in a cohort of pediatric patients with intractable epilepsy undergoing evaluation for surgery and to determine the significance of this finding in the context of surgical planning. METHODS Forty-eight surgically treated children with intractable epilepsy were compared with matched healthy subjects; reviewers were blinded to surgical side. Each temporal lobe was evaluated for rounded hippocampus, blurring, vertical collateral sulcus, wide choroidal fissure, enlarged temporal horn, low fornix, hippocampal signal, and findings of hippocampal sclerosis. A mesial temporal lobe (MTL) score was calculated by summing the number of features, and the collateral sulcus angle (CSA) was measured in each temporal lobe. Surgical side, pathological diagnosis, and imaging findings elsewhere in the brain were tabulated. Presence of HIMAL, associated imaging features, and MTL score were compared between sides, between epilepsy and control groups, in relationship to side of surgery, and in relationship to postoperative outcome. RESULTS Only 3 epilepsy patients (6.2%) and no controls exhibited all 3 features of HIMAL (p = 0.12). Eight of 48 (16.7%) epilepsy versus 2 of 48 (4.6%) control subjects had both a rounded hippocampus and vertical collateral sulcus (suggesting HIMAL) (p = 0.045). In control and epilepsy subjects, most findings were more prevalent on the left, and the left CSA was more vertical (p Epilepsy subjects had higher MTL scores (z = -2.95, p = 0.002) and more acute CSAs (p = 0.04) than controls. Only lateralizing raw MTL score had a significant association with surgical side (p = 0.03, OR 7.33); however, this was not significant when hippocampal sclerosis cases were excluded. HIMAL findings were more prevalent and MTL scores were higher in patients with resections involving the temporal lobes. On group analysis, HIMAL findings did not predict eventual surgical side and did not predict outcome, although the numbers are small. In 4 patients the abnormally rotated hippocampus was resected and showed hippocampal sclerosis and/or dysplastic changes on histopathology. All of these patients had a good outcome after surgery. CONCLUSIONS While increased in prevalence in children with intractable epilepsy, imaging findings of HIMAL did not have preoperative lateralizing utility in this group. Findings of HIMAL (including round hippocampus, architectural blurring, and vertical collateral sulcus) did not predict outcome after surgery, although the small number of patients with these findings limits evaluation. In the small number of patients in which the malrotated hippocampus was removed, outcome was good. Further research is needed to continue to define this association in children with intractable epilepsy, focusing on a temporal lobe cohort.

  10. How do young people from so called “rough area” perceive the society where they are evolving?

    Full Text Available What young people see from the society they are evolving in gives us a clue about and an understanding of the reasons why they sometimes become violent. Young people are revolted because they feel like a lot of things are unfair; they miss “moral values” and “points of reference”, as if nothing made “sense” anymore. Then, consumersociety leads some young people into confusing reality with fictional fact and ultimately creates envy and jealousy. With the evolution of society and the fact that traditional rites “disappear”, young people are faced with the only rite that still exists to “jump” from childhood to grow-up world: school. But those who are not going to school will have to find and search for other “ rites of passage ” and we think that this is a major risk for young people, because this is where they could be “separated” from the society. Having to deal with this evolution, young people have some problems finding people they can identify themselves with.

  11. Evidence of multiple paternity and cooperative parental care in the so called monogamous silver arowana Osteoglossum bicirrhosum (Osteoglossiformes: Osteoglossidae

    Directory of Open Access Journals (Sweden)

    Júlia Tovar Verba

    Full Text Available Monogamy is rare in fishes and is usually associated with elaborate parental care. When parental care is present in fishes, it is usually the male that is responsible, and it is believed that there is a relationship between the high energetic investment and the certainty of paternity (except in the case of sneaker males. Osteoglossum bicirrhosum is considered a monogamous fish, and has particular behavioral traits that permit the study of mating systems and parental care, such as male mouthbrooding. We investigated the genetic relationships of males with the broods found in their oral cavities in Osteoglossum samples collected in a natural environment in the lower Purus river basin, Amazonas, Brazil. Fourteen broods were analyzed for parentage (268 young and 14 adult males using eight microsatellite loci. The results indicate that eleven broods show a monogamous system. In one brood, however, approximately 50% of the young were genetically compatible with being offspring of another male, and in another two broods, none of the subsampled young were compatible with the genotypes of the brooding male. The result of this first brood may be explained by the extra-parental contribution of a sneaker male, whereas cooperative parental care may explain the result in the other two broods.

    Under the Italian Law "Legge Balduzzi", which was issued after the sudden cardiac death of professional athletes Pier Mario Morosini and Vigor Bovolenta in 2012, the presence of an automated external defibrillator (AED) and personnel trained to perform cardiopulmonary resuscitation must be available in every Italian sports facility from 2016. In 2015 the national and local press reported 123 cases of sudden cardiac arrests (SCA) occurring in Italian sport facilities, corresponding to an estimated ≈0.2-0.4% of all SCA and to ≈0.6-1.2% of SCA in public places. The majority of SCA victims were males (93%) and >35 years old (88%, median age 50 years). On the basis of the report of the event on the press, the rate of return of spontaneous circulation was 62% when an AED was used before emergency medical system arrival versus 9% when no bystander cardiopulmonary resuscitation or AED use by lay rescuers was mentioned. These data demonstrated that the Law has the potential to increase the survival to SCA in athletes; however, limiting the obligation of the presence of an AED only to sports facilities is not enough to decrease significantly the incidence of SCA in the general population.

    Gynecomastia is a benign enlargement of male breast, common in adolescents and adults. To treat this deformity, we have been carrying out liposuction through small cutaneous incisions placed in the axilla and on the sternum. If necessary, we performed a surgical excision of glandular tissue through a periareolar incision. From 1995, we started to perform surgical excision of glandular tissue, if necessary, through the small incisions made for liposuction, thus avoiding the periareolar scars. We describe our experience with this technique, which we believe excellent for the correction of glandular and fatty glandular gynecomastia, obtaining excellent esthetic results and minimal local scarring.

    Universal primers targeting the bacterial 16S-rRNA-gene allow quantification of the total bacterial load in variable sample types by qPCR. However, many universal primer pairs also amplify DNA of plants or even of archaea and other eukaryotic cells. By using these primers, the total bacterial load might be misevaluated, whenever samples contain high amounts of non-target DNA. Thus, this study aimed to provide primer pairs which are suitable for quantification and identification of bacterial DNA in samples such as feed, spices and sample material from digesters. For 42 primers, mismatches to the sequence of chloroplasts and mitochondria of plants were evaluated. Six primer pairs were further analyzed with regard to the question whether they anneal to DNA of archaea, animal tissue and fungi. Subsequently they were tested with sample matrix such as plants, feed, feces, soil and environmental samples. To this purpose, the target DNA in the samples was quantified by qPCR. The PCR products of plant and feed samples were further processed for the Single Strand Conformation Polymorphism method followed by sequence analysis. The sequencing results revealed that primer pair 335F/769R amplified only bacterial DNA in samples such as plants and animal feed, in which the DNA of plants prevailed. Copyright © 2015 Elsevier B.V.

    Visual ability and compensatory eye movements during defined vertical oscillation were investigated in 20 patients with unilateral lesions of labyrinthine function and in 20 normal subjects. Oscillation frequencies were performed at the rate of 1 to 1.5 Hz with an amplitude of 5 cm, comparative to head locomotions of a running person. In synchronism with this, the visual function was tested with Landolt rings. Patients complaining of subjective visual disturbance during walking and running, also presented a measurable blur of vision under test conditions. In addition, eye movements were recorded and classified into three types. However, these eye movements showed no relation to gaze function. Our results suggest that the otolith-ocular reflex may participate in adjusting the vertical eye position during vertical stimulations at low frequencies. The effect of visual disturbances in patients with labyrinthine lesions is explained by the "efference-copy" initially described by von Holst. The efference-copy is responsible for the neutralisation of provoked retinal perceptions.

    1997-12-01

    This interpretive research set out to investigate the characteristics of an exemplary college science instructor who endeavors to improve teaching and learning in a physical science course for prospective teachers. The course was innovative in the sense that it was designed to meet the specific needs of prospective elementary teachers who needed to have models of how to teach science in a way that employed materials and small group activities. The central purpose for this study is to understand the metaphors that Mark (a pseudonym), the chemistry instructor in the course, used as referents to conceptualize his roles and frame actions and interactions in the classroom. Within the theoretical frame of constructivism, human cognitive interests, and co-participation theories, an ethnographic research design, described by Erickson (1986), Guba and Lincoln (1989), and Gallagher (1991), was employed in the study. The main sources of data for this study were field notes, transcript analysis of interviews with the instructor and students, and analyses of videotaped excerpts. Additional data sources, such as student journals and the results of students' responses to the University/Community College Student Questionnaire which was developed by a group science education researchers at Florida State University, were employed to maximize that the assertions I constructed were consistent with the variety of data. Data analyses and interpretation in the study focused on identifying the aspects which the instructor and the researcher might find useful in reflecting to understand what was happening and why that was happening in the classroom. The analysis reveals how the instructor used constructivism as a referent for his teaching and the learning of his students. To be consistent with his beliefs and goals that prospective teachers should enjoy their journey of learning chemistry, Mark, the driver in the journey, used the roles of controller, facilitator, learner, and entertainer

    2011-01-01

    Much attention has been paid to so-called "millennial students" in recent years, particularly regarding their relationship to technology, learning, and communication. Less notice has been taken of another kind of millennial student increasingly represented in our classrooms --those who were born in another country, but received a significant amount of their schooling here. Often referred to as Generation 1.5 because they have language characteristics in common with first- and second-generation immigrants, these bilingual students are a valuable resource for the physician assistant (PA) profession. However, just as teaching native-born millennial students may require some adjustment of instructional methods, Generation 1.5 students will require PA educators to pay closer attention to some aspects of teaching and learning. This article will discuss some of the particular challenges that Generation 1.5 students face and will argue that these challenges can be met in ways that are likely to help other nontraditional students as well.

    2009-01-01

    So-called "ASTRO 101” survey courses in general astronomy are offered to non-science majors in colleges and universities across the United States, to fulfill general-education requirements in the physical sciences. At least two of the common Student Learning Outcomes (SLO) for these courses are critical thinking and understanding astronomy as a scientific discipline. We argue that a comprehensive lower-division astronomy program surpassing ASTRO 101 would increase science literacy for non-science majors, STEM students, and the general public. The program would include diverse astronomy course offerings, interdisciplinary science courses (e.g. astrobiology), service-learning and peer-mentoring activities, and internship opportunities.

    Full Text Available The article analyzes nutrition of students, based on the assessment of frequency of consumption of basic food products. The study involved 50 students aged 21-22 years. Set that the nutrition of the majority of students is irrational, in the daily life of young people there is a number of risk factors associated with inadequate intake of healthy food products. Have far-reaching enough food habits due to the consumption of so-called "food waste". The analysis of the correlation relationship between nutrition, mental performance and lifestyle factors, confirmed that a violation of the rules of a healthy diet affects the performance efficiency, increases the likelihood of bad habits. Slow food culture, lack of knowledge of young people on healthy food cause the need for appropriate health education.

  13. Canadian dental students' perceptions of stress.

    2007-05-01

    In this paper, we report the results of a survey on dental student stress carried out in April 2005. A questionnaire was used to collect data from 171 students (62% response rate). Identified stressors were academic, clinic-related, social and financial. "Examination and grades" produced the most academic stress, and inconsistent feedback from instructors created the most clinic-related stress. Students found that having a dual role--wife or husband and dental student--was the most burdensome social stressor. Approximately 60% of students reported marital problems and stress associated with "relations with members of the opposite sex." Survey results showed that students who expected a high graduating debt had higher total and academic stress scores. Total stress was not related to age, gender or marital status. Students living with parents during term time had significantly higher total stress scores than students living in other arrangements. Students residing with parents also had significantly higher debts on entry to dental school. Students with more predental education had (non-significantly) lower stress scores but also had higher student debts. Undergraduate subject major (biological science or non-science) had no bearing on reported stress. This study highlights the negative effects of student debt, the necessity for staff training and the need for further studies exploring relations among stress, psychological well-being and academic performance.

    2015-04-01

    Full Text Available A total of 2,338 students at German universities participated in a survey, which investigated media usage patterns of so-called traditional and non-traditional students (Schuetze & Wolter, 2003. The students provided information on the digital devices that they own or have access to, and on their usage of media and e-learning tools and services for their learning. A distinction was made between external, formal and internal, informal tools and services. Based on the students’ responses, a typology of media usage patterns was established by means of a latent class analysis (LCA. Four types or profiles of media usage patterns were identified. These types were labeled entertainment users, peripheral users, advanced users and instrumental users. Among non-traditional students, the proportion of instrumental users was rather high. Based on the usage patterns of traditional and non-traditional students, implications for media selection in the instructional design process are outlined in the paper.

    Prosperity theology is a variegated movement that overlaps both the Charismatic and non-Charismatic spectrums. This theology certainly has a Charismatic flavouring, but it is by no means limited to Pentecostalism. The prosperity message is being preached world-wide on TBN Television, radio and printed media. This gospel focuses on human potential for successful living, emphasizing health and wealth. There is a clear shift notable from theocentric providence to anthropocentric prosperity in th...

  17. Evaluating the Nature of So-Called S*-State Feature in Transient Absorption of Carotenoids in Light-Harvesting Complex 2 (LH2) from Purple Photosynthetic Bacteria.

    2016-11-03

    Carotenoids are a class of natural pigments present in all phototrophic organisms, mainly in their light-harvesting proteins in which they play roles of accessory light absorbers and photoprotectors. Extensive time-resolved spectroscopic studies of these pigments have revealed unexpectedly complex photophysical properties, particularly for carotenoids in light-harvesting LH2 complexes from purple bacteria. An ambiguous, optically forbidden electronic excited state designated as S* has been postulated to be involved in carotenoid excitation relaxation and in an alternative carotenoid-to-bacteriochlorophyll energy transfer pathway, as well as being a precursor of the carotenoid triplet state. However, no definitive and satisfactory origin of the carotenoid S* state in these complexes has been established, despite a wide-ranging series of studies. Here, we resolve the ambiguous origin of the carotenoid S* state in LH2 complex from Rba. sphaeroides by showing that the S* feature can be seen as a combination of ground state absorption bleaching of the carotenoid pool converted to cations and the Stark spectrum of neighbor neutral carotenoids, induced by temporal electric field brought by the carotenoid cation-bacteriochlorophyll anion pair. These findings remove the need to assign an S* state, and thereby significantly simplify the photochemistry of carotenoids in these photosynthetic antenna complexes.

    Current endoscopic anatomy interposes the gastric cardia between the tubular oesophagus and the proximal stomach. In contrast to that, recent evidence unfolds a different view. Using "PubMed" and "Scopus" searches, we examined if the novel understanding regarding the cardia goes in line with the concept of unfolding, as described by Heidegger based on the ancient didactic poetry of Parmenides. What has been taken as gastric cardia in fact represents reflux-damaged, dilated, columnar lined oesophagus (CLO): dilated distal oesophagus (DDO). Due to its macroscopic gastric appearance it cannot be discriminated from the stomach by endoscopy. Differentiation between DDE and proximal stomach requires the histopathology of measured multi-level biopsies obtained from the DDO and the proximal stomach. Cardaic, onxytocardiac mucosa and intestinal metaplasia (IM; Barrett's oesophagus) define CLO and thus the oesophageal location, while oxyntic mucosa (OM) of the proximal stomach verifies a gastric biopsy location. Endoscopically visible CLO and DDO define the morphological manifestation of reflux: the squamo-oxyntic gap (SOG). Biopsies obtained from the level of the diaphragmatic impressions allow differentiation between an enlarged hiatus with normal anatomic content (CLO; oesophagus) vs. hernia with abnormal content (OM; stomach). Non-dysplastic Barrett's oesophagus exists in 10 %-17 % of asymptomatic and in 20 %-100 % (with increasing CLO length) of reflux symptom-positive individuals (annual cancer risk: 0.2 %-0.7 %). These data justify biopsy of an endoscopically normal appearing squamocolumnar junction for the exclusion of Barrett's oesophagus and cancer risk. In the absence of contraindications, cancer risk-based therapy of dysplastic Barrett's oesophagus includes radiofrequency ablation (RFA) ± endoscopic resection. The perception of the cardia as reflux damaged DDO mirrors the concept of unfolding, as described by the interpretation of the didactic poem of Parmenides by Heidegger. Our data recommend to omit the term "cardia" and allocate morphology either to the oesophagus (CLO, DDO) or to the proximal stomach or indicate that allocation is impossible (i. e.. tumour-induced). Future studies will have to test the value of this novel concept for diagnosis, treatment of gastro-oesophageal reflux disease and cancer prevention. © Georg Thieme Verlag KG Stuttgart · New York.

    Mg(OH) 2 - and Mg(OH) 2 -containing materials can provide excellent performance as supports for AuPd nanoparticles for the oxidation of glycerol in the absence of base, which is considered to be a result of additional basic sites on the surface of the support. However, its influence on the reaction solution is not generally discussed. In this paper, we examine the relationship between the basic Mg(OH) 2 support and AuPd nanoparticles in detail using four types of catalyst. For these reactions, the physical interaction between Mg(OH) 2 and AuPd was adjusted. It was found that the activity of the AuPd nanoparticles increased with the amount of Mg(OH) 2 added under base-free conditions, regardless of its interaction with the noble metals. In order to investigate how Mg(OH) 2 affected the glycerol oxidation, detailed information about the performance of AuPd/Mg(OH) 2 , physically mixed (AuPd/C+Mg(OH) 2 ) and (AuPd/C+NaHCO 3 ) was obtained and compared. Furthermore, NaOH and Mg(OH) 2 were added during the reaction using AuPd/C. All these results indicate that the distinctive and outstanding performance of Mg(OH) 2 supported catalysts in base-free condition is in fact directly related to its ability to affect the pH during the reaction and as such, assists with the initial activation of the primary alcohol, which is considered to be the rate determining step in the reaction. © 2018 Wiley-VCH Verlag GmbH & Co.

    Currently, computed tomography (CT) is widely used to evaluate the efficacy of treatments on tumor regression in unresectable pancreatic head carcinomas. Recently, 18 F-fluorodeoxyglucose positron emission tomography (PET) examination has been used for the initial diagnosis of pancreatic tumors, for diagnosis of distant metastasis, and for recurrences of pancreatic carcinomas. PET has also been used for the qualitative diagnosis of existing tumors. The current study was designed to observe if PET examination can be used to gauge the efficacy of multidisciplinary treatments, and to estimate the prognosis for unresectable pancreatic head carcinomas in similar clinical stages and during therapy. This was a prospective cohort study and included 18 cases. All cases were unresectable pancreatic head cancers diagnosed as TNM classification stage 3, and had undergone identical multidisciplinary treatment regimens. The level of tumor markers, tumor-size reduction, and maximum standardized uptake values (SUV max ) were correlated with prognosis. Pearson's correlation and Kaplan-Meyer survival rate curves were used for statistical analysis. Tumor-size reduction in CTs and the transition of tumor markers were not related to patient prognosis. Cases in which post-treatment SUV max values were reduced to <3.0 were correlated with a more favorable prognosis and demonstrated extended survival rates. PET examination can be used to estimate the prognosis of unresectable pancreatic head carcinomas which have undergone multidisciplinary treatments. (author)

    For poorly differentiated rhinopharyngeal carcinomas, the clinical presentation (association with the Epstein-Barr virus, paraneoplastic syndromes, onset of lymphoma) and the histopathological features can be polymorphous and they can confound or delay diagnosis and preparation of an adequate treatment plan (radio-chemotherapy). Often these neoplasms arise as clinically primitive laterocervical metastases, masked by clinical findings and a history that can lead to the mistaken diagnosis of systemic lymphoproliferative processes such as Hodgkin's disease. Here an observation of this type is presented in a young patient (19 years old) who came under observation for a laterocervical tumefaction recurrent from a previous exeresis performed at another hospital and symptoms of serotine febricula, dysphagia and serology positive for the Epstein-Barr virus (EBV). The patient underwent surgery and then radiotherapy and has been under close post-operative follow-up for two years. To date the patient's condition--both local and general--is good. The particular histology of the neoformation lies in the abundant infiltration of plasma cell and lymphocyte eosinophils, at times in blastic form. Moreover, elements with a large clear nucleus and evident nucleolus (Hodgkin-like) and scattered multinucleate Langhans-type giant cells can be seen. Immunohistologically the tumor cells markedly express for cytokeratin and the latent membrane protein (LMP1) of the Epstein-Barr virus (EBV) and show a high growth fraction. Under the electron microscope, the plurinucleate giant cells present large nuclei with morphology similar to that of tumor cells. The clear cytokeratin-positivity of the tumor elements and the histological and ultrastructural features mentioned led to the diagnosis of a massive metastasis from lymphoepithelial carcinoma, the Schmincke variant, plus EBV infection of the neoplastic cells. The authors conclude assuming that the particular granulomatous reaction is due to the host's reaction to the tumor cells, but also to the reaction to the viral antigens. In the former case we find an attempt to limit the carcinomatous process; in the latter it is a response caused by the EBV and is not, apparently, aimed at protecting against the neoplasm rather it facilitates the neoplastic process.

    To describe the clinical spectrum associated with aminoacyl-transfer RNA synthetase (ARS) autoantibodies in patients with idiopathic inflammatory myositis defined according to Peter and Bohan's criteria. Cohort studies were selected from MEDLINE and Embase up to August 2013. Two investigators independently extracted data on study design, patient characteristics, and clinical features (interstitial lung disease [ILD], fever, mechanic's hands [MH], Raynaud's phenomenon [RPh], arthralgia, sclerodactyly, cancer and dermatomyositis-specific rash) according to the presence of myositis-specific (anti-aminoacyl-transfer RNA synthetase [ARS], anti-signal recognition particle [anti-SRP] and anti-Mi2) and myositis-associated (anti-PM/Scl, anti-U1-RNP and anti-Ku) autoantibodies. 27 studies (3487 patients) were included in the meta-analysis. Arthralgia (75%, CI 67-81) and ILD (69%, CI 63-74) were the most prevalent clinical signs associated with anti-ARS autoantibodies. Anti-Mi2 and anti-SRP autoantibodies were associated with few extramuscular signs. ARS autoantibodies were identified in 13% of patients with cancer-associated myositis (5-25). Patients with non-anti-Jo1 ARS had greater odds of presenting fever (RR 0.63, CI 0.52-0.90) and ILD (RR 0.87, CI 0.81-0.93) compared to those with anti-Jo1 autoantibodies. The frequencies of myositis (RR 1.60, CI 1.38-1.85), arthralgia (RR 1.52, CI 1.32-1.76) and MH (RR 1.47, CI 1.11-1.94) were almost 50% higher in patients with anti-Jo1 compared to non-anti-Jo1 ARS autoantibodies. Patients with anti-PM/Scl differed from those with anti-ARS autoantibodies by a greater prevalence of RPh (RR 0.70, CI 0.53-0.94) and sclerodactyly (RR 0.47, CI 0.25-0.89). ILD was less frequent in patients with anti-U1-RNP autoantibodies (RR 3.35, CI 1.07-10.43). No difference was observed between anti-ARS and myositis-associated autoantibodies for other outcomes. The presence of anti-ARS autoantibodies delimits a heterogeneous subset of patients with a high prevalence of myositis, MH, arthralgia in anti-Jo1 patients, and RPh and fever in non-anti-Jo1 patients. The clinical signs of populations positive for anti-PM/Scl and anti-ARS autoantibodies largely overlap, especially with regard to ILD, challenging the clinical delimitation of the antisynthetase syndrome.

    INTRODUZIONE: una vasta area compresa tra le province di Napoli e Caserta nella regione Campania ha negli ultimi anni attirato l'attenzione dei mass media a causa degli interramenti illeciti di rifiuti di varia origine nei campi o del loro abbandono lungo le strade. A tali pratiche illecite si aggiunge il fenomeno dei roghi incontrollati di questo materiale, motivo per il quale la zona è stata soprannominata "Terra dei fuochi". OBIETTIVI: ricerca di elementi in tracce presenti nei prodotti alimentari di origine vegetale prodotti nella Terra dei fuochi. DISEGNO E SETTING: piano di monitoraggio per il rilevamento dei livelli di alcuni metalli tossici ed essenziali nei vegetali coltivati in Campania nella Terra dei fuochi. La determinazione dei microelementi è stata effettuata dopo mineralizzazione della sostanza organica mediante microonde, utilizzando la spettrometria di massa a plasma induttivamente accoppiato (ICP-MS). RISULTATI: durante l'attività di monitoraggio sono stati raccolti 65 campioni di ortaggi e 49 campioni di frutta in 43 comuni rientranti nella Terra dei fuochi. Il contenuto medio di metalli tossici, cadmio e piombo nei prodotti ortofrutticoli è risultato ben lontano dai limiti massimi fissati dalla normativa europea. I valori delle concentrazioni sono significativamente inferiori rispetto a quanto riscontrato in zone ad alto impatto ambientale a causa della presenza di impianti industriali. CONCLUSIONI: la presenza di elementi tossici o potenzialmente tali nei campioni vegetali prodotti nella Terra dei fuochi è attribuibile a una varietà di fattori ambientali rilevanti (caratteristiche geologiche dell'area, inquinamento del suolo, dell'atmosfera e delle acque di irrigazione, pratiche illecite di smaltimento dei rifiuti industriali); non sembra, tuttavia, sussistere un rischio per la salute dei consumatori. Resta comunque l'allerta per la loro presenza nell'ambiente e la necessità che le attività di monitoraggio continuino.

  5. La patrimonialisation des produits dits de terroir Heritage-making and the enhancement of so-called ‘terroir’ products: when rural meets urban

    Directory of Open Access Journals (Sweden)

    2011-05-01

    Full Text Available Aujourd’hui, le phénomène de patrimonialisation des produits agro-alimentaires concerne des campagnes rêvées à forte identité, mais aussi des espaces apparemment « sans qualité », des espaces « en creux ». La patrimonialisation des produits de terroir passe par différents processus : par le biais de fêtes, de la mise en art, de la gastronomie, ainsi que par des modes de vente comme le marché… Ces processus à l’œuvre montrent que la relation au monde rural est complexe. En effet, la patrimonialisation des produits de terroir peut aussi bien être le fait d’acteurs ruraux que d’acteurs urbains, de politiques de territoire urbaines que rurales. Les produits de terroir apparaissent comme un dénominateur commun réunissant, au moins occasionnellement, anciens, nouveaux habitants, voire habitants temporaires de territoires qui se dessinent. Ce phénomène est analysé à partir de trois exemples pris dans la région Rhône-Alpes: la fête de la fourme et des Côtes du Forez et la stratégie d’affirmation d’une petite ville, Montbrison, comme capitale d’un pays, le Forez ; Bourg-en-Bresse et sa volaille, ou comment des produits de terroir peuvent contribuer à affirmer une urbanité ; enfin, l’analyse de la création d’une marque territoriale pour affirmer l’existence d’un espace « sans nom », situé à l’ombre de métropoles et la nécessité de protéger sa ruralité face au phénomène de résidentialisation.Today, the enhancement of food heritage concerns not only rural areas with cultural identities but also areas which seem « without quality » or « hollowed out». The enhancement of local products (produits de terroir entails various processes such as festivals, art events, local gastronomy and sales outlets provided by local markets. These processes reveal just how complex the links with local places are. In fact, local product enhancement can result as much from rural activities (local players, rural policies as urban ones (city people and city policies. Local products appear as a common denominator uniting, albeit occasionally, old residents, new residents or temporary residents of emerging territories. The present study considers this aspect of local products in the context of three examples from the Rhone-Alpes region in France.

  6. On the separation of so-called non-volatile uranium fission products of uranium using the conversion of neutron-irradiated uranium dioxide and graphite

    International Nuclear Information System (INIS)

    Elhardt, W.

    1979-01-01

    The investigations are continued in the following work which arose from the concept of separating uranium fission products from uranium. This is achieved in that due to the lattice conversions occurring during the course of solid chemical reactions, fission products can easily pass from the uranium-contained solid to a second solid. The investigations carried out primarily concern the release behaviour of cerium and neodymium in the temperature region of 1200 to 1700 0 C. UO 2 + graphite, both in powder form, are selected as suitable reaction system having the preconditions needed for the lattice conversion for the release effect. The target aimed at from the practical aspect for the improved release of lanthanoids is achieved by an isobar test course - changing temperature from 1200 to 1500 0 C at constant pressure, with a cerium release of 75-80% and a neodynium release of 80-90% (maximum at 1400 0 C). The concepts on the mechanism of the fission product release are related to transport processes in crystal lattices, as well as chemical solid reactions and evaporation processes on the surface of UC 2 grains.

  7. The determination of irradiation and so-called terrestrial ageing of rock meteorites based on the cosmogenic resulting radionuclides 53Mn and 26Al

    Englert, P.

    1979-01-01

    The contents of cosmogenic occuring 53 Mn was determined by neutron activation in over 90 samples of 75 individual rock meteorites. The distinct depth effect of the 53 Mn production rate in rock meteorites could be measured by a depth profile at LL6 chondrite St. Severin (falling weight 271 kg). The experimental results confirm the present model concepts. By comparing with the spallogenic 22 Ne/ 21 Ne and 3 He/ 21 Ne ratios applicable as depth indicators, one could derive linear relationships suitable for correcting 53 Mn. They enable the determination of the average 53 Mn production rate from the saturation activities of long-term irradiated meteorites. Using this method it was possible to calculate the irradiation age of 40 rock meteorites. As 26 Al is formed with a similar effective cross-section to 53 Mn, the production rate ratio 53 Mn: 26 Al was also taken to derive the depth-independent irradiation ages. A method to determine the depth-independent terrestrial ageing of meteriorites has been developed based on the same isotope ratio, the effective field of application is between 0.10 to 2x10 6 a. Furthermore, an attempt was made to draw up the dependence of noble gas contents of 53 Mn resp. 53 Mn/ 26 Al irradiation age for the new determination of the 3 He, 21 Ne and 38 Ar production rates by means of a linear regression analysis.

    Meerwein, F; Kauf, S; Schneider, G

    1976-01-01

    Drawing on their experience with their own cancer patients and with the Balint Group in the Oncological Department of Zürich's University Hospital, the authors describe the special problems arising in the doctor-patient relationship in this field. They show how the diagnosis of cancer can give rise to a feeling of sudden and complete object loss in the patient, thereby confronting the doctor with his own fear of death. The mobilization of archaic defence mechanisms in both the doctor and the patients can lead to an insoluble double-blind situation unless the doctor is able to give up his defence position and thus make it possible for the patient to give up his own fear of death and to accept the nature of his illness. The authors show how the doctor can break through the isolation of the patient in whose body-ego an archaic bad inner-object has been activated by the cancer, and build up good inner objects for him again. In the last chapter Winnicott's idea the "intermediate area" is shown to shed a new light on the phenomenon of redenial or belief in immortality.

    Methods: A systematic study is presented, comparing teeth with a manifest radiation caries (group 1, about 60 Gy, long interval to the extraction) and clinically caries free teeth (group 2, about 30 Gy, short interval) with tooth specimens after an experimental enoral (in situ) irradiation (60 Gy, group 3) and after in vitro irradiation (500 to 2.500 Gy, group 4). 60 Co was the irradiation source. Sound teeth were used as a standard (group 5). For non destructive visualisation of subsurface histotomograms by confocal laser scanning microscopy (CLSM) teeth were either used as fresh sections or as Technovit embedded thin slices (sawing grinding technique). Results: Tooth samples from radiotherapy patients (cancer therapeutic doses, long interval before extraction; group 1) showed three characteristic changes: 1. Rarefication of the branching (ramification) of odontoblast processes near the junction, 2. dentine tubules end infront of the interface to the hard tissue and 3. in dentine the interface is characterised by a zone (about 10 μm wide) of low intensity of the remitted light. Conclusions: The obliteration of the dentine tubules, preceded by a degeneration of the odontoblast processes, is obviously the result of a direct radiogenic cell damage with hampered vascularisation and metabolism particularly in the area of the terminations of the odontoblast processes. The deficit in metabolism combined with a latent damage of the parenchyma (hypo-remitting zone) is evidence for the functional symptoms (subsurface caries). The prerequisite for the micromorphological manifestation of this direct irradiation damage is a vital tooth and in consequence cannot be simulated in situ or in vivo. (orig./MG) [de

    Full Text Available According to the research it was revealed that students with health problems (handicapped students in general seldom take responsibility for the events happening to them, and rarely analyze the situation and their possibilities and more often try to distance from the problem. According to the data obtained the handicapped students demonstrate the problems with coping strategies in the cognitive sphere. The article also gives the analysis of the gender peculiarities of coping behavior of the handicapped students. It is revealed that such girls-students in comparison with so called conditionally healthy peers are more often ready to have a conflict or to try to cope with the problem subjectively diminishing its importance and degree of their emotional involving into it. The handicapped boys at the same time, are less ready for confrontation, rarely confess their responsibility for the problem and the responsibility for solving it and also have less tendency for direct analysis of the situation and possible variants of behavior, for working out the strategy of the problem solving and planning their actions considering objective conditions, previous experience and resources. Further on, the character of relations between different coping strategies of handicapped and conditionally healthy students was analyzed. It was revealed that the main relations between different copings of conditionally healthy students are on the scales Problem-solving Planning and Positive re-estimation. It is possible to suggest that for these (healthy students these coping strategies compose the core of the mechanisms of coping behavior. On the contrary, handicapped students (with health problems the definite correlational connections are absent. So in the case of handicapped students it is impossible to speak about some definite core in the system of coping behavior.

    Full Text Available This paper researches the so-called “dark triad” personality traits of management student populations, because of their potential to generate dysfunctional organizational behavior and processes. Namely, the dark triad with characteristics such as lack of empathy, willingness to manipulate others (for self-betterment, antagonism, and belief in one’s own superiority can represent a real organizational threat. The goal of this paper is to stimulate thinking and discussion around this issue. The paper is based on questionnaire measurement that adopts the standardized short dark triad measurement instrument of Jones and Paulhus (2012 who measure the scales of Machiavellianism (9 items, narcissism (9 items and psychopathy (9 items. The sample included 150 students of professional management studies at the Faculty of Economics, University of Split in Croatia. Results of the Croatian students are compared with the results of 387 students in Canada. The results suggest significant statistical differences in the “dark triad” variables between the Canadian and Croatian samples. The practical implications of this paper are in raising awareness and stimulating the thinking of managers around the potential of the “dark triad” traits of engaged human resources to create organizational crisis, and to make preventive and responsive actions to manage the “toxic triad” threat.

    Field trips have always been one of the major attractions of geoscience education, distinguishing courses in geology, geography, oceanography, etc., from laboratory-bound sciences such as nuclear physics or biochemistry. However, traditional field trips have been limited to regions with educationally useful exposures and to student populations with the necessary free time and financial resources. Two-year or commuter colleges serving worker-students cannot realistically insist on completion of field assignments and even well-endowed universities cannot take students to more than a handful of the best available field localities. Many instructors have attempted to bring the field into the classroom with the aid of technology. So-called Virtual Field Trips (VFTs) cannot replace the real experience for those that experience it but they are much better than nothing at all. We have been working to create transformative improvements in VFTs using four concepts: (i) self-drive virtual vehicles that students use to navigate the virtual globe under their own control; (ii) GigaPan outcrops that reveal successively more details views of key locations; (iii) virtual specimens scanned from real rocks, minerals, and fossils; and (iv) embedded assessment via logging of student actions. Students are represented by avatars of their own choosing and travel either together in a virtual field vehicle, or separately. When they approach virtual outcrops, virtual specimens become collectable and can be examined using Javascript controls that change magnification and orientation. These instructional resources are being made available via a new server under the domain name www.DigitalPlanet.org. The server will log student progress and provide immediate feedback. We aim to disseminate these resources widely and welcome feedback from instructors and students.

    2010-12-01

    Students enrolled in an undergraduate non-science majors’ Energy Perspectives course created 10-15 minute video documentaries on topics related to Energy Resources and the Environment. Video project topics included wave, biodiesel, clean coal, hydro, solar and “off-the-grid” energy technologies. No student had any prior experience with creating video projects. Students had Liberal Arts academic backgrounds that included Anthropology, Theater Arts, International Studies, English and Early Childhood Education. Students were required to: 1) select a topic, 2) conduct research, 3) write a narrative, 4) construct a project storyboard, 5) shoot or acquire video and photos (from legal sources), 6) record the narrative, and 7) construct the video documentary. This study describes the instructional approach of using student created video documentaries as projects in an undergraduate non-science majors’ science course. Two knowledge survey instruments were used for assessment purposes. Each instrument was administered Pre-, Mid- and Post course. One survey focused on the skills necessary to research and produce video documentaries. Results showed students acquired enhanced technology skills especially with regard to research techniques, writing skills and video editing. The second survey assessed students’ content knowledge acquired from each documentary. Results indicated students’ increased their content knowledge of energy resource topics. Students reported very favorable evaluations concerning their experience with creating “Ken Burns” video project documentaries.

    The use of digital video for science education has become common with the wide availability of video imagery. This study continues research into aspects of using digital video as a primary teaching tool to enhance student learning in undergraduate science courses. Two survey instruments were administered to undergraduate non-science majors. Survey One focused on: a) What science is being learned from watching science videos such as a "YouTube" clip of a volcanic eruption or an informational video on geologic time and b) What are student preferences with regard to their learning (e.g. using video versus traditional modes of delivery)? Survey Two addressed students' perspectives on the storytelling aspect of the video with respect to: a) sustaining interest, b) providing science information, c) style of video and d) quality of the video. Undergraduate non-science majors were the primary focus group in this study. Students were asked to view video segments and respond to a survey focused on what they learned from the segments. The storytelling aspect of each video was also addressed by students. Students watched 15-20 shorter (3-15 minute science videos) created within the last four years. Initial results of this research support that shorter video segments were preferred and the storytelling quality of each video related to student learning.

    Full Text Available Thematic focus: The motor abnormalities may be part of so-called comorbidities that can coexist with autistic disorder. Objective: To characterize the motor profile of students with autistic disorder. Method: the study included six children with autistic disorder in elementary school, male, aged 5 years and 5 months and 10 years and 9 months. After signing the consent form by parents or guardians, the students were submitted to the Motor Development Scale for assessment of fine motor, gross motor performance, balance, body scheme, spatial organization, temporal organization and laterality. Results: The results revealed a significant difference between the motor age and chronological age. According to the classification of the Scale of Motor Development, students in this study showed motor development lower than expected for age. Conclusion: The students with autistic disorder in this study presented a profile of Developmental Coordination Disorder in comorbidity, showing that participants of this research presented difficulties in activities that required skills such as handwriting. Thus, motor and psychomotor needs of these students were focused on educational and clinical environment to reduce the impact of behavioral and social manifestations.

    This study aims to identify whether non-science graduates perform as well as science graduates in Basic and Clinical Sciences (B & CS) assessments during Years 1-3 of a four-year graduate-entry programme at the University of Sydney (the 'USydMP'). Students were grouped into five categories: Health Professions (HP), Biomedical Sciences (BMS), Other Biology (BIOL), Physical Sciences (PHYS) or Non-Science (NONS). We examined the performance rank of students in each of the five groups for single best answer (SBA) and modified essay (MEQ) assessments separately, and also calculated the relative risk of failure in the summative assessments in Years 2 and 3. Students with science-based prior degrees performed better in the SBA assessments. The same occurred initially in the MEQs, but the effect diminished with time. The HP students performed consistently better but converged with other groups over time, particularly in the MEQs. Relative performance by the NONS students improved with time in both assessment formats. Overall, differences between the highest and lowest groups were small and very few students failed to meet the overall standard for the summative assessments. HP and BMS students had the lowest failure rate. NONS students were more likely to fail the assessments in Year 2 and 3, but their pass rates were still high. Female students performed significantly better overall at the end of Year 2 and in Year 3. There were only minor differences between Australian resident and International students. While there are small differences in performance in B & CS early in the programme, these lessen with time. The study results will inform decisions regarding timing of summative assessments, selection policy and for providing additional support to students who need it to minimize their risk of failure. Readers should note that this paper refers to student performance in only one of the four curriculum themes, where health professional and science graduates would be

The framework is based on viewing problem solving as a modelling process. In order to solve a real-world problem, the problem...... solver has to go through the steps and do the tasks of such a process. The paper presents a theoretical analysis of what it takes to solve three real-world problems, demonstrating how the framework presented captures the essential aspects of solving them. Moreover, it is argued that three steps critical...... for real-world problem solving – initial analysis of the problem situation, choice of relevant physical theory (the so-called paradigmatic choice) and mathematization – are not covered by existing models of problem solving in Physics.

    Course-based undergraduate research is known to improve science, technology, engineering, and mathematics student achievement. We tested "The Small World Initiative, a Citizen-Science Project to Crowdsource Novel Antibiotic Discovery" to see if it also improved student performance and the critical thinking of non-science majors in Introductory Biology at Florida Atlantic University (a large, public, minority-dominant institution) in academic year 2014-15. California Critical Thinking Skills Test pre- and posttests were offered to both Small World Initiative (SWI) and control lab students for formative amounts of extra credit. SWI lab students earned significantly higher lecture grades than control lab students, had significantly fewer lecture grades of D+ or lower, and had significantly higher critical thinking posttest total scores than control students. Lastly, more SWI students were engaged while taking critical thinking tests. These results support the hypothesis that utilizing independent course-based undergraduate science research improves student achievement even in nonscience students.

    Full Text Available Objective: This study investigates students’ entrepreneurial activities and aims to answer questions regarding to what extent do students utilize the knowledge gained during their studies and the personal connections acquired at universities, as well as what role a family business background plays in the development of students’ business start-ups. Research Design & Methods: This paper is based on the database of the GUESSS project investigates 658 student entrepreneurs (so-called ‘active entrepreneurs’ who have already established businesses of their own. Findings: The rate of self-employment among Hungarian students who study in tertiary education and consider themselves to be entrepreneurs is high. Motivations and entrepreneurial efforts differ from those who owns a larger company, they do not necessarily intend to make an entrepreneurial path a career option in the long run. A family business background and family support play a determining role in entrepreneurship and business start-ups, while entrepreneurial training and courses offered at higher institutions are not reflected in students’ entrepreneurial activities. Implications & Recommendations: Universities should offer not only conventional business courses (for example, business planning, but also new forms of education so that students meet various entrepreneurial tasks and problems, make decisions in different situations, explore and acquaint themselves with entrepreneurship. Contribution & Value Added: The study provides literature overview of youth entrepreneurship, describes the main characteristics of students’ enterprises and contributes to understanding the factors of youth entrepreneurship.

    2016-10-01

    This research explored how engineering student views of their responsibility toward helping individuals and society through their profession, so-called social responsibility, change over time. A survey instrument was administered to students initially primarily in their first year, senior year, or graduate studies majoring in mechanical, civil, or environmental engineering at five institutions in September 2012, April 2013, and March 2014. The majority of the students (57 %) did not change significantly in their social responsibility attitudes, but 23 % decreased and 20 % increased. The students who increased, decreased, or remained the same in their social responsibility attitudes over time did not differ significantly in terms of gender, academic rank, or major. Some differences were found between institutions. Students who decreased in social responsibility initially possessed more positive social responsibility attitudes, were less likely to indicate that college courses impacted their views of social responsibility, and were more likely to have decreased in the frequency that they participated in volunteer activities, compared to students who did not change or increased their social responsibility. Although the large percentage of engineering students who decreased their social responsibility during college was disappointing, it is encouraging that courses and participation in volunteer activities may combat this trend.

    Mlenga, Francis Howard

    The purpose of the study was to determine factors affecting elementary female student teachers' choice of science as a major at college level in Zimbabwe. The study was conducted at one of the Primary School Teachers' Colleges in Zimbabwe. A sample of two hundred and thirty-eight female student teachers was used in the study. Of these one hundred and forty-two were non-science majors who had been randomly selected, forty-one were science majors and forty-five were math majors. Both science and math majors were a convenient sample because the total enrollment of the two groups was small. All the subjects completed a survey questionnaire that had sixty-eight items. Ten students from the non-science majors were selected for individual interviews and the same was done for the science majors. A further eighteen were selected from the non-science majors and divided into three groups of six each for focus group interviews. The same was done for the science majors. The interviews were audio taped and transcribed. Data from the survey questionnaires were analyzed using Binary Logistic Regression which predicted factors that affected students' choice of science as a major. The transcribed interview data were analyzed used using domain, taxonomic and componential analyses. Results of the study indicated that elementary female students' choice of science as a major at college level is affected by students' attitudes toward science, teacher behavior, out-of-school experiences, role models, gender stereotyping, parental influence, peer influence, in-school experiences, and societal expectations, namely cultural and social expectations.

  4. Moral Perceptions of College Science Students

    Science.gov (United States)

    Nolan, Eric

    This thesis argues that college-level science education is in need of explicit moral focuses centered on society's use of scientific knowledge. Many benefits come with scientific advancements but unfortunately the misuse of scientific knowledge has led to planetary crises that should be a concern for all who inhabit the Earth (e.g., climate change). The teaching of the misuses of science is often left out of college science classrooms and the purpose of this thesis is to see what effect college science students' education has had on their moral perception of these pressing issues. To evaluate how college science students morally perceive these global issues within their educational experiences, two focus group interviews were conducted and analyzed. Students converged on three themes when thinking of society's misuse of science: 1) there is something wrong with the way science is communicated between science and non-science groups; 2) misusing science for private benefit is not right, and 3) it is important for people to comprehend sustainability along different scales of understanding and action. This thesis concludes that although to some extent students were familiar with moral features that stem from society's misuse of science, they did not attribute their learning of those features from any of their required coursework within their programs of study.

    An observational study was conducted to evaluate hygiene habits of students with fields of study, gender, and understanding of hygiene at a university in Alabama. One hundred students were randomly observed in ten restrooms on campus to determine whether or not students washed their hands. The study was divided into an observational stage, a quiz to ascertain student's knowledge of hygiene and the spread of pathogens, and a survey of self-reported illness rates. Females had a tendency to wash their hands more often than males while visiting the bathroom (p = 0.02, chi2 = 11.6). Science majors were more likely to wash their hands than non-science majors (p < or = 0.001, chi2 = 5.2). Females (p < or = 0.0001, df = 98, F = 21.5) and science majors (p < or = 0.0001, df = 98, F = 81.4) scored significantly higher on the survey than males and nonscience majors, and that those observed not washing their hands reported being sick more often than those observed washing their hands (chi2 = 155.0, df= 3, p < 0.001, Fisher's exact p < 0.001).

    Pelger, Susanne; Sigrell, Anders

    2016-01-01

    Background: Feedback is one of the most significant factors for students' development of writing skills. For feedback to be successful, however, students and teachers need a common language - a meta-language - for discussing texts. Not least because in science education such a meta-language might contribute to improve writing training and feedback-giving. Purpose: The aim of this study was to explore students' perception of teachers' feedback given on their texts in two genres, and to suggest how writing training and feedback-giving could become more efficient. Sample: In this study were included 44 degree project students in biology and molecular biology, and 21 supervising teachers at a Swedish university. Design and methods: The study concerned students' writing about their degree projects in two genres: scientific writing and popular science writing. The data consisted of documented teacher feedback on the students' popular science texts. It also included students' and teachers' answers to questionnaires about writing and feedback. All data were collected during the spring of 2012. Teachers' feedback, actual and recalled - by students and teachers, respectively - was analysed and compared using the so-called Canons of rhetoric. Results: While the teachers recalled the given feedback as mainly positive, most students recalled only negative feedback. According to the teachers, suggested improvements concerned firstly the content, and secondly the structure of the text. In contrast, the students mentioned language style first, followed by content. Conclusions: The disagreement between students and teachers regarding how and what feedback was given on the students texts confirm the need of improved strategies for writing training and feedback-giving in science education. We suggest that the rhetorical meta-language might play a crucial role in overcoming the difficulties observed in this study. We also discuss how training of writing skills may contribute to

    Full Text Available This study examined the relationships between emotional intelligence (EI and the delinquent behavior (DB of the students. The level of DB reported by the students is categorized under the headings of crime, drugs, vandalism, pornography and sexual behavior, other misbehavior, and dishonesty. Meanwhile, EI is investigated by looking at the level of EI domains, such as self-awareness, self-regulation, self-motivation, empathy, social skills, maturity, and spiritual awareness. Data were gathered from a sample of 300 secondary school students aged 15 to 18 years in Selangor. The schools they attended were selected from the so-called “hardcore schools,” which were identified by Schools Division in the State of Selangor. Two instruments, namely, surveys on the “Behavior of Students” and “Malaysian Emotional Quotient Inventory (R–Adolescence (MEQI,” were utilized to collect the research data and were analyzed using SPSS 19.0. The data showed that the highest delinquency among the adolescents was misbehavior in school, followed by crime, vandalism, pornography, dishonesty, and drugs. Results also revealed a negative linear relationship between EI (r = −.208, n = 300, p = .001 and DB, implying that adolescents with better EI had lower levels of delinquency. Multiple regression analysis revealed that EI is a significant predictor of DB and self-awareness is the main factor of DB. This study contributes to the knowledge of the importance of EI in understanding DB. EI can be used to identify and discriminate emotional skills among those adolescents who exhibit DB. Addressing the role of EI as a predictor would probably prove to be effective in reducing DB.

  8. How volunteering helps students to develop soft skills

    2017-06-01

    It is widely recognised that tertiary education does not provide all of the knowledge and skills required to succeed in modern societies. Personal and interpersonal skills - so-called "soft skills" - are also needed to complement professional skills and expertise, and become an essential part of an individual's personality. One way of acquiring soft skills is volunteering with associations and non-governmental organisations (NGOs). This paper discusses the involvement of French third-level students in voluntary activities and the skills they acquire as a result. The author presents the findings of a study involving a questionnaire and semi-structured interviews. Results show that many students develop skills linked to their future professional career, that they reflect on this consciously and feel enriched by the experience. The author argues that "non-professional" activities like volunteering can be actively incorporated into students' learning process, making their overall experience of higher education more active, enjoyable and relevant. Learning through action was found to be the most important factor in the acquisition of soft skills. This article aims to contribute to research on the educational dimension of volunteering, demonstrating that it benefits both personal and professional development.

    Informal and formal lifelong learning is essential at university and in the workplace. Apart from classical learning techniques, Web 2.0 tools can be used. It is controversial whether there is a so-called net generation amongst people under 30. To test the hypothesis that a net generation among students and young veterinarians exists. An online survey of students and veterinarians was conducted in the German-speaking countries which was advertised via online media and traditional print media. 1780 people took part in the survey. Students and veterinarians have different usage patterns regarding social networks (91.9% vs. 69%) and IM (55.9% vs. 24.5%). All tools were predominantly used passively and in private, to a lesser extent also professionally and for studying. The use of Web 2.0 tools is useful, however, teaching information and media skills, preparing codes of conduct for the internet and verification of user generated content is essential.

    Full Text Available Teachers play an important role in honing students’ knowledge and skills. The strategy used in teaching greatly affects the final result of students learning. Hence, the teacher should properly plan and organize the strategy to be used. In this paper, we presented another teaching strategy in mathematics which is more fun and easier for students to understand mathematical concepts like factoring polynomials. We devised the so-called Substitute It With Icons or (SIWI as teaching strategy in factoring polynomials by common monomial. Results revealed that SIWI is more helpful among low achievers group compared to high achievers who still preferred the old variable number style. It is recommended to try out SIWI with other mathematics topic like Algebra.

  11. Student Mastery of the Sun-Earth-Moon System in a Flipped Classroom of Pre-service Elementary Education Students

    Larsen, Kristine

    2014-01-01

    One of the current trends in pedagogy at all levels(K-college) is the so-called ‘flipped classroom’, in which students prepare for a class meeting through self-study of the material. It is based on a rejection of the classic model of the faculty member as the ‘sage on the stage’ instead, responsibility for learning shifts to the individual student. The faculty member takes on the role of learning facilitator or mentor, and focuses the students’ learning by crafting and administering timely formative assessments (in multiple formats and applied multiple times) that aid both students and the faculty member in tracking the students’ mastery of the learning outcomes. In a flipped, freshman-only, section of SCI 111 Elementary Earth-Physical Sciences (a required introductory science course for pre-service elementary school teachers) the students learned through a combination of individual and group hands-on in-class activities, technology (including PowerPoint presentations and short videos viewed prior to attending class), in-class worksheets, and in-class discussions. Students self-differentiated in how they interacted with the available teaching materials, deciding which activities to spend the most time on based on their individual needs (based on an online quiz taken the night before the class period, and their personal self-confidence with the material). Available in-class activities and worksheets were developed by the faculty member based on student scores on the online quiz as well as personal messages submitted through the course management system the night before the class meeting. While this placed a significant burden on the faculty member in terms of course preparation, it allowed for just-in-time teaching to take place. This poster describes the results of student mastery of content centered on the sun-earth-moon system (specifically seasons, moon phases, and eclipses) as compared to traditional classroom sections.

  12. Gender stereotypes among women engineering and technology students in the UK: lessons from career choice narratives

    Powell, Abigail; Dainty, Andrew; Bagilhole, Barbara

    2012-12-01

    In the UK, women remain under-represented in engineering and technology (E&T). Research has, therefore, investigated barriers and solutions to women's recruitment, retention and progression. Recruitment into the sector may be supported by exploring the career decisions of women and men who have chosen to study E&T. Triangulating quantitative and qualitative data from E&T students at a UK university, this paper examines the gendered nature of career choice narratives. It finds that women often maintain contradictory views; upholding gendered stereotypes about women's suitability for the so-called masculine work, yet also subscribing to ideals that the sector is accessible to all who wish to work in it. This is explained using an individualist framework in which women construct an autonomous sense of self, yet are also shaped by a gendered self. Women's discourse around career choice, therefore, reveals the problematic nature of gender norms for achieving gender equity in E&T.

    To address the effectiveness of a formal postbaccalaureate (PB) experience for underrepresented minority (URM) students before medical school. The program provided an intense year-long experience of course work, research, and personal development. There were 516 participants from one medical school: 15 URM medical students had completed the formal PB program, 58 students had done independent PB work before matriculation, and 443 students were traditional matriculants. Cognitive and academic indicators [college science and non-science grade-point averages (GPAs); biology, physics, and verbal MCAT scores; and percentage scores from first-year medical school courses] were compared for the three groups. Both groups of students with PB experience demonstrated competency in the first year of medical school consistent with traditional students even though the students who had completed the formal PB program had lower MCAT scores and lower college GPAs than did the traditional students. Traditional predictors of academic performance during the first year of medical school did not significantly contribute to actual academic performances of students from the formal PB program. The results support the use of a formal PB program to provide academic readiness and support for URM students prior to medical school. Such a program may also improve retention. Noncognitive variables, however, may be important to understanding the success of such students in medical school.

    For several years the Spanish University has been experiencing changes that affect not only the educational area but also innovation and investigation in the classroom. Even the use of so-called New Technologies has been focus of much attention in the Higher Educational System, student mentoring has been revealed as an important factor in the first university courses. In this sense, we carried out a first step in a senior student mentor project in order to facilitate adaptation of the new students, providing information, advice and guidance on different academic and social aspects. Here, we understand mentoring as a relationship between a more senior student (mentor) and a few junior lesser experienced students (mentees). Mentoring is intended to develop and grow the skills, knowledge, confidence, and cultural understanding of the mentees aiming to help them succeed. Consequently, this work arises from our concern about students need. A test has been designed to assess students interest in the three fundamental aspects of mentoring: academic, social and administrative orientation. The test involved 16 questions related to these three different aspects on mentoring, evaluating each question from 1 (none) to 4 (totally). Surveys have been conducted on this topic at the Universidad Politécnica de Madrid (UPM) with students on different levels and modules of degrees in Agricultural Engineering. The same activity has been applied to the new degrees that have started at 2010-11 course in the Bologna Plan's requirements and are replacing the precedents progressively. We have analysed the answers performing a multifactor analysis of variance for each question. It constructs various tests and graphs to determine which questions have statistically significant interactions, given sufficient data. The F-tests in the ANOVA table allowed identifying the significant ones. For each significant factor, the Multiple Range Tests (MRT) tells which means are significantly different

    Evidence in support for the concept of the so-called 'siesta culture' is not well developed and has, to date, relied largely on qualitative anthropological data. Presumably such cultures are characterized by a strong tendency for daytime naps and daytime sleepiness, phenomena which may partially represent the effects of geographic, climatic or light conditions and/or cultural influences. In this study we surveyed the nocturnal sleep habits and daytime sleep tendencies of 577 Mexican college students residing in Mexico City (19 degrees N latitude). Results indicated a number of parallels between the reported sleep habits of these students and those reported from other cultures at latitudes far to the north (North America, Europe), such as longer sleep at the weekends, an association between snoring and daytime sleepiness and a lack of relationship between nocturnal sleep duration and the reported tendency to nap. There was some suggestion that these Mexican students may actually nap less when compared to other college student populations. Taken together, these results call into question what is meant by the concept of a 'siesta culture', at least in this urban, educated, upper social economic scale (SES) population, and suggest that future studies in equatorial regions be undertaken to further appreciate the role of climate, photoperiod and/or culture in the tendency for humans to nap during the day.

    Five radio shows; a full-page color spread in the campus newspaper; YouTube videos; an interactive activity at the local children's museum; a star party for a dorm; children's books; an outing with Boy Scouts. This is just a sampling of group projects planned and executed in a single semester by students in an introductory course for non-science majors. Everyone in the class joins a group self-organized around common interests to produce a product or activity that communicates some aspect of astronomy to a segment of the general population. These projects give the students a creative outlet to merge some of their outside interests with the course material, a practical exposure to scientific communication, an opportunity for peer instruction including peer evaluation, and a chance to hone their skills in managing group dynamics. The semester long effort begins with everyone in the class submitting individual ideas for subjects and presentation methods. After these ideas are categorized, students begin organizing the groups on a web discussion board. They articulate learning goals for the intended audience and describe how they plan to evaluate the success of the project and the attainment of these goals. The group members seek outside advice from people in other groups during one week of the course discussion section. They submit a progress report and then a first draft, the latter also sent to a different group for review. After feedback from the instructor and a week of the teaching assistant's (TA's) office hours devoted to scheduled meetings with each group, the students draft the final versions or make presentations near the end of the semester.

    Three hundred seven undergraduate students enrolled in Introductory Astronomy were surveyed at the beginning of class to determine their expectations for course content. The course serves as a survey of astronomy for non-science majors and is a distribution course for general education core requirements. The course has no prerequisites, meets three times each week for 50 minutes, and represents three semester credit hours. The university catalog describes the course with the title "PHYSICS 101 - Mysteries of the Sky" and the official course description is: a survey of the struggle to understand the Universe and our place therein. The structure, growth, methods, and limitations of science will be illustrated using the development of astronomy as a vehicle. Present day views of the Universe are presented. Two questions were asked as open response items: What made you decide to take this course? and What do you expect to learn in this course? The reasons that students cited to take the course, in order of frequency, were: interested in astronomy, interesting or fun sounding course, required general education fulfillment, recommendation by peer. Secondary reasons cited were required for major or minor, general interest in science, and was available in the schedule. Tertiary reasons listed were recommendation by advisor or orientation leader, inflate grade point average, and heard good things about the teacher. The students' expectations about what they would learn in the course were numerous. The most common objects listed, in order of frequency, were: stars, constellations, planets, galaxies, black holes, solar system, comets, galaxies, asteroids, moon, and Sun. More interesting were the aspects not specifically related to astronomy. These were weather, atmosphere, UFOs and the unexplained, generally things in the sky. A mid-course survey suggests that students expected to learn more constellations and that the topics would be less in-depth.

    Popular media influences ideas about science constructed by the public. To sway media productions, public policy organizations have increasingly promoted use of science consultants. This study contributes to understanding the connection from science consultants to popular media to public outcomes. A science-based television series was examined for intended messages of the creator and consulting scientist, and received messages among middle school and non-science university students. The results suggest the consulting scientist missed an opportunity to influence the portrayal of the cultural contexts of science and that middle school students may be reading these aspects uncritically-a deficiency educators could potentially address. In contrast, all groups discussed the science content and practices of the show, indicating that scientific facts were salient to both media makers and audiences. This suggests popular media may influence the public knowledge of science, supporting concerns of scientists about the accuracy of fictional television and film.

    Nursing care prevention programs cannot accomplish their goals without effective screening of pre-frail older people. Health check-up services provide a very opportunity for this purpose. In the present study we examined not only the direct and indirect effects of social networks on check-up service use among candidate pre-frail older people, but also whether these effects differ from those among older people in general. Subjects for this study were respondents of a survey for probability sampled aged 65 and over living in a city, Tokyo. Individuals who gave effective responses to items used in our analysis made up 55.8 percent of the sample. 734 candidate pre-frail older people were selected using the screening criteria provided by the ministry of Heath, Labor and Welfare. The general category of older people numbered 2,057, excluding the candidates and elderly certified for long-term care. Social networks were measured from five aspects: family size; contact with children or relatives living separately; contact with neighbors or friends; involvement in community activities; and seeing a doctor. Our model of indirect effects of social networks on check-up use included awareness of nursing care prevention programs as a mediating factor. Information about whether the subjects used the health check-up service was provided.by the regional government. Magnitude of the effects was evaluated from two aspects; using statistical tests and focusing on marginal effects. Although none of the social network indicators had direct significant impacts on check-up use, contact with children or relatives living separately, contact with neighbors or friends, or involvement with community activities demonstrated significant indirect influence. Contact with neighbors or friends, involvement with community activities, or seeing a doctor had direct significant effects on use among the general category of older people, but none of the social network indicators demonstrated significant indirect effects. Involvement with community activities had the strongest total (direct plus indirect) effects on the use in the social networks indicators among the candidates when viewed with the focus on marginal effects. However, it was estimated that the rate of use would raise only about 5 percent even if average frequency of contacts with community activities were to increase from less than one time to one time over a month among the candidates. It is suggested that effects of social networks on health check-up service use among candidates of pre-frail older people could be produced by improving awareness of nursing care prevention programs.

    We report on 11 patients from 8 families with a blepharophimosis and mental retardation syndrome (BMRS) phenotype. Using current nosology, five sporadic patients have Ohdo syndrome, associated with congenital hypothyroidism in two of them (thus also compatible with a diagnosis of Young-Simpson syndrome). In two affected sibs with milder phenotype, compensated hypothyroidism was demonstrated. In another family, an affected boy was born to the unaffected sister of a previously reported patient. Finally, in the last sibship, two affected boys in addition had severe microcephaly and neurological anomalies. A definitive clinical and etiologic classification of BMRS is lacking, but closer phenotypic analysis should lead to a more useful appraisal of the BMRS phenotype. We suggest discontinuing the systematic use of the term "Ohdo syndrome" when referring to patients with BMRS. We propose a classification of BMRS into five groups: (1) del(3p) syndrome, (possibly overlooked in older reports); (2) BMRS, Ohdo type, limited to the original patients of Ohdo; (3) BMRS SBBYS (Say-Barber/Biesecker/Young-Simpson) type, with distinctive dysmorphic features and inconstant anomalies including heart defect, optic atrophy, deafness, hypoplastic teeth, cleft palate, joint limitations, and hypothyroidism. BMRS type SBBYS is probably an etiologically heterogeneous phenotype, as AD and apparently AR forms exist; (4) BMRS, MKB (Maat-Kievit-Brunner) type, with coarse, triangular face, which is probably sex-linked; (5) BMRS V (Verloes) type, a probable new type with severe microcephaly, hypsarrhythmia, adducted thumbs, cleft palate, and abnormal genitalia, which is likely autosomal recessive. Types MKB and V are newly described here. Copyright 2006 Wiley-Liss, Inc.

  4. The hypothesis of a postpositional compensatory lengthening (so-called van Wijk’s law vs. the relative chronology of Common Slavic phonologi­cal devel­opments – in search of inconsistencies

    Full Text Available “Van Wijk’s law” is currently defined by its advocates as a lengthening of short or shortened medial and final vowels due to an assimilation of the postconsonantal *j to them. In the present paper I am trying to demonstrate that this assumption is at variance with the relative chronology of Slavic, according to which the loss of yod after liquids and nasals must be dated before the rise of new timbre distinctions and before the shortening of final long vowels.

    International Nuclear Information System (INIS)

    1999-01-01

    This Directive was adopted by the European Council of Ministers in 1996. All member states are required to transpose it into domestic law by May 2000. In the UK the transposition is taking place in two parts, revision of the Ionising Radiation Regulations - consultation on this closed a year ago; revision of the Radioactive Substances Act 1993 - consultation closes on 25th June 1999 A further round of consultation is promised for the autumn. The Department of Environment, Transport, and the Regions (DETR) is the lead department. The Directive covers all aspects of ionising radiation. Most of it is uncontentious, but hidden within the text are deregulatory provisions which threaten to allow a flood of contaminated materials into landfill and incinerators, and even into consumer goods. Radioactivity is under regulation inside licensed sites, where radiation doses are mostly to workers who are monitored and are compensated for detrimental effects by the social and financial benefits of having employment. This is in line with the ICRP 'Justification' principle to which all authorities pay lip service. Waste is recycled reused incinerated, and dumped, steadily increasing the general level of man-made radioactivity in the environment, and exposing the unwitting public whose doses are not monitored, whose health detriment is written off as trivial, and who obtain no social or economic benefit to offset the exposure. Contrary to official assumptions about radioactive discharges in the environment, distribution does not become uniform. Many nuclides reconcentrate through a variety of as yet poorly described physical and biological mechanisms, thus exposing the population unequally. Hot particles remain a permanent source of high local doses to tissue following ingestion and/or inhalation

    Whilst the majority of young people succeed in education and make a positive transition to the world of work and adult life, recent statistics identify that youth comprise 40% of the world's unemployed, equating to nearly 75 million individuals. These numbers are associated with both decreased economic activity and adverse well-being, with accompanying social, health and financial costs. As a result, a wide range of providers have implemented interventions targeting this population; however, their relative effectiveness is unknown. This is exacerbated by a diverse literature base, the delivery of provision and policy across multiple sectors and disparate approaches to programme evaluation. We will undertake a systematic review of interventions targeting youth not in employment, education or training (NEET) populations. Only randomised and non-randomised controlled trials will be included. The objectives of the review will be to: (i) systematically review, synthesise and quality appraise experimental evidence on the effects of interventions with NEET young people, (ii) estimate effects on current NEET status, well-being and other relevant psychological and behavioural outcomes, (iii) investigate potential variation in intervention effects among sub-groups stratified by pre-trial duration of current status, socioeconomic status, gender, sub-classifications of NEET individuals and intervention components (e.g. type, frequency, duration, provider and setting) and (iv) assess the robustness of results in separate sensitivity analyses that exclude studies with higher risk of bias (e.g. in terms of study quality) or follow-up length. A rigorous literature search of English language publications post-1990 will be conducted using the following electronic databases: Medline, Embase, PsycINFO, ERIC, EPPI-Centre (Bibliomap), Social Science Citation Index, British Education Index, Conference Proceedings Index, Dissertation Abstracts, Popline and grey literature collections (e.g. GLADNET). These database searches will be supplemented with hand searching, requests for unpublished literature and website searches. A report and executive summary will be developed by the research team with input from consultant stakeholders to aid translation of the findings into practice. The research will be disseminated at national and international conferences and submitted for peer-reviewed publication. PROSPERO CRD42014007535.

    Full Text Available Research on unconventional medical practices among students has proliferated lately in the global space, hitherto, little is known explicitly in Ghana. This paper teases out insights for recent utilisation patterns of traditional medical therapies at Kwame Nkrumah University of Science and Technology (KNUST, Ghana. A sample of 754, randomly selected undergraduates were involved in a retrospective cross-sectional survey. Data were analysed using multivariate logistic regression and Pearson's χ2 test with p < 0.05 as significant. Overall prevalence of traditional therapies consumption was 89.1% in the last 12 months. Herbal-based products (67%, prayer healing (15% and body-mind therapies (11% were principally used and, accessed through purchases from pharmacy shops (29% and encounter with faith healers (26%. Although students' knowledge on traditional therapies was acquired through family members (50% and media (23%, literary materials remained significant information routes for Science related students compared to the Non-science related counterparts (p < 0.001.

Although students exhibited positive attitude towards unconventional therapies, there is an urgent need to validate the quality of traditional therapies through randomised clinical trials and regulatory practices to ensure quality control. Health forces should intensify efforts towards intercultural health care system in Ghana.

    Full Text Available From the student movement emerged in Chile in 2011, the article reflects on the school as a learning space of audiovisual digital technologies and how this process can impact on the political communication dimension of a social movement. To do this, it is described and analyzed the case of a school where formal education in languages and digital technologies is overlapping with the use of applications and resources of the social web and so-called "social media" (youtube, blogs, social networks by high school students who become student leaders. Data are generated through key informant interviews and a selection of videos created for the students and uploaded to the Internet. The content of the interviews is approached from the concept of situated learning (Lave & Wenger, 1991 and videos from the concept of video activism (Askanius, 2013; Mateos & Rajas, 2014. The results show that concrete use of digital tools obtained in formal educational spaces in a context of mobilization processes, generates new experiences of non-formal learning, which allow both students and teachers to reflect on their communicative practices and improve them. They also show an uncritical use of digital tools, which is a wake-up call on the need to incorporate privacy and self-care topics in internet within the contents to be developed by the school as space for digital learning.

    2017-01-01

    Massive Open Online Courses (MOOCs) are large-scale, free classes open to anyone around the world and are are part of an educational industry that includes a growing number of universities. Although they resemble formal classes, MOOCs are of interest to instructors and educational researchers because they are unique learning environments where various people--particularly adult learners--learn science. This research project examined learners in an astronomy MOOC in order to better understand the motivations of MOOC learners. Using a well-tested instrument that examines student motivations for learning, we wanted to compare the motivations of MOOC learners to previous results in undergraduate classrooms. Our results show that our MOOC learners scored high in intrinsic motivation, self-efficacy, and self-determination. They differed from learners in traditional formal educational environments by having lower grade and career-related motivations. These results suggest that MOOC learners have characteristics of learners in so called “free-choice” learning environments, similar to other life-long learners.

  12. Exploring the role of physics representations: an illustrative example from students sharing knowledge about refraction

    Fredlund, Tobias; Airey, John; Linder, Cedric

    2012-01-01

    Research has shown that interactive engagement enhances student learning outcomes. A growing body of research suggests that the representations we use in physics are important in such learning environments. In this paper we draw on a number of sources in the literature to explore the role of representations in interactive engagement in physics. In particular we are interested in the potential for sharing disciplinary knowledge inherent in so-called persistent representations (such as equations, diagrams and graphs), which we use in physics. We use selected extracts from a case study, where a group of senior undergraduate physics students are asked to explain the phenomenon of refraction, to illustrate implications for interactive engagement. In this study the ray diagram that was initially introduced by the students did not appear to sufficiently support their interactive engagement. However, the introduction of a wavefront diagram quickly led their discussion to an agreed conclusion. From our analysis we conclude that in interactive engagement it is important to choose appropriate persistent representations to coordinate the use of other representations such as speech and gestures. Pedagogical implications and future research are proposed. (paper)

Development of football isn't possible without search and introduction in training process of optimum pedagogical models of perfection of physical and technical readiness of football players. Such pedagogical models should be applied, as in groups of initial preparation, so at the subsequent grade levels, including in student's football. Modern training process (pedagogical model, should be under construction on objective indicators of physical, technical and special readiness (so-called feedback. However, the estimation of sports-technical readiness at sports schools on football is reduced only to testing of speed, jumps, juggling, dribbling and a shoot for goal. The same criteria are applied and in student's football. Unfortunately, the given control exercises not in a condition to the full to reflect level of physical and technical readiness of the football player. For more objective estimation of special readiness it is necessary to use the test tasks revealing a level of development of coordination abilities of game structure game and competitive activity (game in football.

As a result coach have possibility to trace level of a condition of the various parties of sports readiness (physical, technical and coordination student's youth engaged in football at each stage of long-term preparation.

  14. University Students' Knowledge Structures and Informal Reasoning on the Use of Genetically Modified Foods: Multidimensional Analyses

    Wu, Ying-Tien

    2013-10-01

    This study aims to provide insights into the role of learners' knowledge structures about a socio-scientific issue (SSI) in their informal reasoning on the issue. A total of 42 non-science major university students' knowledge structures and informal reasoning were assessed with multidimensional analyses. With both qualitative and quantitative analyses, this study revealed that those students with more extended and better-organized knowledge structures, as well as those who more frequently used higher-order information processing modes, were more oriented towards achieving a higher-level informal reasoning quality. The regression analyses further showed that the "richness" of the students' knowledge structures explained 25 % of the variation in their rebuttal construction, an important indicator of reasoning quality, indicating the significance of the role of students' sophisticated knowledge structure in SSI reasoning. Besides, this study also provides some initial evidence for the significant role of the "core" concept within one's knowledge structure in one's SSI reasoning. The findings in this study suggest that, in SSI-based instruction, science instructors should try to identify students' core concepts within their prior knowledge regarding the SSI, and then they should try to guide students to construct and structure relevant concepts or ideas regarding the SSI based on their core concepts. Thus, students could obtain extended and well-organized knowledge structures, which would then help them achieve better learning transfer in dealing with SSIs.

    The development of new technologies has provided medical education with the ability to enhance the student learning experience and meet the needs of changing curricula. Students quickly adapt to using multimedia learning resources, but these need to be well designed, learner-centred and interactive for students to become significantly engaged. One way to ensure that students become committed users and that resources become distinct elements of the learning cycle is to involve students in resource design and production. Such an approach enables resources to accommodate student needs and preferences, but also provides opportunities for them to develop their own teaching and training skills. The aim of the medical student research project was to design and produce an electronic resource that was focused on a particular anatomical region. The views of other medical students were used to decide what features were suitable for inclusion and the resulting package contained basic principles and clinical relevance, and used a variety of approaches such as images of cadaveric material, living anatomy movies and quizzes. The completed package was assessed using a survey matrix and found to compare well with commercially available products. Given the ever-diversifying arena of multimedia instruction and the ability of students to be fully conversant with technology, this project demonstrates that students are ideal participants and creators of multimedia resources. It is hoped that such an approach will help to further develop the skill base of students, but will also provide an avenue of developing packages that are student user friendly, and that are focused towards particular curricula requirements. © Blackwell Publishing Ltd 2012.

    2017-01-01

    The paper deals with software tools focused on radiation protection, which were created within the framework of cooperation between the SURO, and FSV CVUT. The tools were created mainly in the framework of bachelor and master's theses on topics listed by the SURO. This is the development of additional specialized tools / extensions (so-called plugins) for the QGIS open-source application used at the SURO for data processing from field measurements and their presentation in the form of map outputs (using free map data such as OpenStreetMap). Students' work is a functional and ideally debug plug-in for QGIS, including complete documentation and source code released under the GNU GPL license - all the plugins thus created will be available to those interested in the public.

    Cassani, Mary Kay Kuhr

    The objective of this study was to evaluate the effect of two pedagogical models used in general education science on non-majors' science teaching self-efficacy. Science teaching self-efficacy can be influenced by inquiry and cooperative learning, through cognitive mechanisms described by Bandura (1997). The Student Centered Activities for Large Enrollment Undergraduate Programs (SCALE-UP) model of inquiry and cooperative learning incorporates cooperative learning and inquiry-guided learning in large enrollment combined lecture-laboratory classes (Oliver-Hoyo & Beichner, 2004). SCALE-UP was adopted by a small but rapidly growing public university in the southeastern United States in three undergraduate, general education science courses for non-science majors in the Fall 2006 and Spring 2007 semesters. Students in these courses were compared with students in three other general education science courses for non-science majors taught with the standard teaching model at the host university. The standard model combines lecture and laboratory in the same course, with smaller enrollments and utilizes cooperative learning. Science teaching self-efficacy was measured using the Science Teaching Efficacy Belief Instrument - B (STEBI-B; Bleicher, 2004). A science teaching self-efficacy score was computed from the Personal Science Teaching Efficacy (PTSE) factor of the instrument. Using non-parametric statistics, no significant difference was found between teaching models, between genders, within models, among instructors, or among courses. The number of previous science courses was significantly correlated with PTSE score. Student responses to open-ended questions indicated that students felt the larger enrollment in the SCALE-UP room reduced individual teacher attention but that the large round SCALE-UP tables promoted group interaction. Students responded positively to cooperative and hands-on activities, and would encourage inclusion of more such activities in all of the

    Students today process information very differently than those of previous generations. They are used to getting their news from 140-character tweets, being entertained by You-Tube videos, and Googling everything. Thus, traditional passive methods of content delivery do not work well for many of these millennials. All students, regardless of career goals, need to become scientifically literate to be able to function in a world where scientific issues are of increasing importance. Those who have had experience applying scientific reasoning to real-world problems in the classroom will be better equipped to make informed decisions in the future. The problem to be solved is how to present scientific content in a manner that fosters student learning in today's world. This presentation will describe how the appeal of technology and social communication via creation of documentary-style videos has been used to engage students to learn scientific concepts in a university non-science major course focused on energy and the environment. These video projects place control of the learning experience into the hands of the learner and provide an opportunity to develop critical thinking skills. Students discover how to locate scientifically reliable information by limiting searches to respected sources and synthesize the information through collaborative content creation to generate a "story". Video projects have a number of advantages over research paper writing. They allow students to develop collaboration skills and be creative in how they deliver the scientific content. Research projects are more effective when the audience is larger than just a teacher. Although our videos are used as peer-teaching tools in the classroom, they also are shown to a larger audience in a public forum to increase the challenge. Video will be the professional communication tool of the future. This presentation will cover the components of the video production process and instructional lessons

    Joliet Junior College, Joliet, IL offers a one semester introductory astronomy course each semester. We teach over 110 primarily non-science major students each semester. We use proven active learning strategies such lecture tutorials, think-pair-share questions and small group discussions to help these students develop and retain a good understanding of astrophysical concepts. Occasionally, we offer projects that allow students to explore course topics beyond the classroom. We hope that such projects will increase students' interest in astronomy. We also hope that these assignments will help students to improve their critical thinking and writing skills. In Spring 12, we are offering three short individual essay assignments in our face-to-face sections. The essays focus on transits, eclipses and occultations to highlight the 2012 transit of Venus. For the first essay, students will find images of transit and occultation events using the Astronomy Picture of the Day website and describe their chosen events. In addition, students will predict how variations in certain physical and orbital parameters would alter their particular events. The second essay involves transits, eclipses and occultations observed by spacecraft. Students will describe their transit event, their spacecraft's mission, orbital path, how the orbital path was achieved, etc. The third essay deals with transiting exoplanets. Students will choose at least two exoplanets from an exoplanet database, one of which has been discovered through the transit method. This essay will enable students to learn about detecting exoplanets and how they compare with our solar system. Details of the essay assignments and students' reactions to them will be presented at the meeting.

    Today's society is continuously coping with sustainability-related complex issues in the Science-Technology-Environment-Society (STES) interfaces. In those contexts, the need and relevance of the development of students' higher-order cognitive skills (HOCS) such as question-asking, critical-thinking, problem-solving and decision-making capabilities within science teaching have been argued by several science educators for decades. Three main objectives guided this study: (1) to establish "base lines" for HOCS capabilities of 10th grade students (n = 264) in the Israeli educational system; (2) to delineate within this population, two different groups with respect to their decision-making capability, science-oriented (n = 142) and non-science (n = 122) students, Groups A and B, respectively; and (3) to assess the pre-post development/change of students' decision-making capabilities via STES-oriented HOCS-promoting curricular modules entitled Science, Technology and Environment in Modern Society (STEMS). A specially developed and validated decision-making questionnaire was used for obtaining a research-based response to the guiding research questions. Our findings suggest that a long-term persistent application of purposed decision-making, promoting teaching strategies, is needed in order to succeed in affecting, positively, high-school students' decision-making ability. The need for science teachers' involvement in the development of their students' HOCS capabilities is thus apparent.

    Full Text Available The free and open publication of course materials (OpenCourseWare or OCW was initially undertaken by Massachusetts Institute of Technology (MIT and other universities primarily to share educational resources among educators (Abelson, 2007. OCW, however, and more in general open educational resources (OER1, have also provided well-documented opportunities for all learners, including the so-called “informal learners” and “independent learners” (Carson, 2005; Mulder, 2006, p. 35. Universities have also increasingly documented clear benefits for specific target groups such as secondary education students and lifelong learners seeking to enter formal postsecondary education programs.In addition to benefitting learners, OCW publication has benefitted the publishing institutions themselves by providing recruiting advantages. Finally enrollment figures from some institutions indicate that even in the case of the free and open publication of materials from online programs, OCW does not negatively affect enrollment. This paper reviews evaluation conducted at Massachusetts Institute of Technology, Johns Hopkins Bloomberg School of Public Health (JHSPH, and Open Universiteit Nederland (OUNL concerning OCW effects on higher education participation and student recruitment.

    Introductory-level Earth science courses provide the opportunity for science and non-science majors to expand discipline-specific content knowledge while enhancing skill sets applicable to all disciplines. The outcomes of the student work can then benefit the education and outreach efforts of an international organization - in this case, a wiki devoted exclusively to the geosciences, managed by the Society of Exploration Geophysicists (SEG). The course Environment Earth at Penn State Brandywine is a general education science course with the overarching course goal for students to understand, communicate examples, and make informed decisions relating to big ideas and fundamental concepts of Earth science. To help accomplish this goal, students carry out a semester-long digital engaged scholarship project that benefits the users of the SEG Wiki (http://wiki.seg.org/). To begin with developing the literacy of students and their ability to read, interpret, and evaluate sources of scientific news, the first assignment requires students to write an annotated bibliography on a specific topic that serves as the foundation for a new SEG Wiki article. Once students have collected and summarized information from reliable sources, students learn how writing for a wiki is different than writing a term paper and begin drafting their wiki page. Students peer review each other's work for content and clarity before publishing their work on the SEG wiki. Students respond positively to this project, reporting a better understanding of and respect towards the authors of online wiki pages, as well as an overall satisfaction of knowing their work will benefit others.

    1986-01-01

    Opinions of students of Tokyo Gakugei University concerning the energy problems are investigated. Comparison is made between the natural science group (231 students) and the nonnatural science group (162 students: about 1/4 mathematics, about 3/4 literature, art etc.). The majority choose nuclear fission, nuclear fusion and solar energy as future energy. About half of them are in favour of development of nuclear fission, but about 1/3 wants keeping nuclear fission at the present level or abolishing it. The science group is more favourable to nuclear fission. Oil depletion is the strongest reason for development of nuclear fission, while the problem of radioactive wastes is the strongest reason for opposition, major accidents being the second. Most of the students oppose construction of nuclear power plants in their neighbourhood, but the science group is more favourable to the construction than the non-science group. Knowledge about natural radiations is very poor, but about 1/4 ∼ 1/5 knows the release of radioactivities from thermal power plants. Knowledge about the greenhouse effect is unexpectedly high. Especially 81 % of male students in the science group knows it. The majority do not understand the energy balance of nuclear energy, but those who answer that the energy balance holds is more than those who answer that it does not. In general the science group and males answer more correctly and are more favourable to nuclear fission. Comparison with other opinion polls is made and it is found that their general tendencies are in agreement. (author)

    2013-12-01

    Full Text Available Learning by practice, apprenticeship and paradigmatic examples have been prime paths for learning within interaction design. These have been criticized for being time-consuming and costly, of not being implementable in academic contexts. In this article we suggest and evaluate a pedagogical model to address these problems in design teaching and learning. Results from a time-constrained collaborative design exercise, a so-called “interactionary”, are presented. Student design work is analyzed using the framework of learning design sequences and analysis of the primary transformation unit shows that interactionaries reveal patterns in student design work. Materials are used mainly to document design ideas rather than as a design material to further investigate design ideas and aspects of interaction. In the critiquing sessions, regarded as the secondary transformation unit, many issues hardly addressed during the design work were brought up. Thus, the designers continued to develop their design proposal primed by critique presented by the reviewers. Based on the results, possible teacher interventions to coach student design work are suggested.

    Full Text Available The legislation governing the Spanish educational system, seems apparently focused on of a constructivist approach of the teaching-learning process. The methodology of this model aims to build students’ learning through interaction in the classroom, with the help of a teacher who acts as a guide. It is, the refore, consustantial to it, the peer learning in a context of cooperative interaction. Within the general trend towards the application of Information and communications technology (ICT in education, there is special interest in the search for tools to facilitate collaborative learning in schools. At the theoretical level, there have been many studies on this subject. In practical terms, numerous applications have been developed based on the so-called Web 2.0 which try to encourage this type of learning. This research describes the general assessment that a group of students from a secondary school performed on the cooperative work. It also describes the frequency of use of ICT (and specifically Google Drive application as a tool for cooperative work, perceived use fulness, and influence student motivation. In all cases, the assessment of students was clearly positive.

    2010-05-01

    Large introductory astronomy and physics survey courses can be very challenging and stressful. The University of Wisconsin-Madison Physics Learning Center (PLC) reaches about 10 percent of the students in four introductory physics courses, algebra and calculus based versions of both classical mechanics and electromagnetism. Participants include those potentially most vulnerable to experiencing isolation and hence to having difficulty finding study partners as well as students struggling with the course. They receive specially written tutorials, conceptual summaries, and practice problems; exam reviews; and most importantly, membership in small groups of 3 - 8 students which meet twice per week in a hybrid of traditional teaching and tutoring. Almost all students who regularly participate in the PLC earn at least a "C,” with many earning higher grades. The PLC works closely with other campus programs which seek to increase the participation and enhance the success of underrepresented minorities, first generation college students, and students from lower-income circumstances; and it is well received by students, departmental faculty, and University administration. The PLC staff includes physics education specialists and research scientists with a passion for education. However, the bulk of the teaching is conducted by undergraduates who are majoring in physics, astronomy, mathematics, engineering, and secondary science teaching (many have multiple majors). The staff train these enthusiastic students, denoted Peer Mentor Tutors (PMTs) in general pedagogy and mentoring strategies, as well as the specifics of teaching the physics covered in the course. The PMTs are among the best undergraduates at the university. While currently there is no UW-Madison learning center for astronomy courses, establishing one is a possible future direction. The introductory astronomy courses cater to non-science majors and consequently are less quantitative. However, the basic structure

    able to develop a (basic) plan to evacuate people from the affected regions. Based on the abilities of your group you can vary the task in many different ways, such as adding information on traffic and public or private transportation to the scenario. Didactic Aspects: Nevertheless it cannot be aim of such a project to develop of a real-life evacuation plan, as this would exceed your student's abilities by far. The focus should rather be on the process of dealing with the problem and developing solutions to it, than on the mere product e.g. a complete plan. This approach corresponds with recent tendencies in German didactics of teaching geography at school favoring the so-called "prozessorientiertes Experimentieren"(see: Lethmate, Otto and Wilhelmi for further reference) as part of training your students (geographic) skills. Applied to the presented task of developing an evacuation plan, you should encourage your students to give argumentative proof for the decisions they make in order to compare their results from a problem solving perspective. Overview: What: process- driven role-play "planning evacuation in case of an eruption of a potentially active volcano (Laacher See)" For whom: adjustable from German form 8-11 (age: 14- 17 years) Time: depending on the prior knowledge of volcanoes a min. of 45-90 minutes.

    In the last decade, educational neuroscience has become increasingly important in the context of instruction, and its applications have been transformed into new teaching methods. Although teachers are interested in educational neuroscience, communication between scientists and teachers is not always straightforward. Thus, misunderstandings of neuroscientific research results can evolve into so-called neuromyths . The aim of the present study was to investigate the prevalence of such music-related neuromyths among music teachers and music students. Based on an extensive literature research, 26 theses were compiled and subsequently evaluated by four experts. Fourteen theses were selected, of which seven were designated as scientifically substantiated and seven as scientifically unsubstantiated (hereafter labeled as "neuromyths"). One group of adult music teachers ( n = 91) and one group of music education students ( n = 125) evaluated the theses (forced-choice discrimination task) in two separate online surveys. Additionally, in both surveys person-characteristic variables were gathered to determine possible predictors for the discrimination performance. As a result, identification rates of the seven scientifically substantiated theses were similar for teachers (76%) and students (78%). Teachers and students correctly rejected 60 and 59%, respectively, of the seven neuromyths as scientifically unsubstantiated statements. Sensitivity analysis by signal detection theory revealed a discrimination performance of d' = 1.25 ( SD = 1.12) for the group of teachers and d' = 1.48 ( SD = 1.22) for the students. Both groups showed a general tendency to evaluate the theses as scientifically substantiated (teachers: c = -0.35, students: c = -0.41). Specifically, buzz words such as "brain hemisphere" or "cognitive enhancement" were often classified as correct.

Some of the participants on the trip to Chamonix enjoy the breath-taking scenery.For many young people, their time at CERN can be filled not only with exciting opportunities but also anxious uncertainty. Whether your stay is for just a few months or a few years, it can be quite daunting to arrive at a new place and try to find your way around – and let’s face it, CERN is not an easy place to find your way around! Much of their time here is spent on doing analysis or technical work on the experiments or the LHC; but even at the end of the day or on weekends there are few social outlets at CERN geared just towards young people. Fortunately, some young people have decided to come together and make their time here not just productive, but fun! Doctoral student, Omer Khalid, Marie Curie fell...

  3. Communication strategies: Implications for EFL university students [İletişim stratejileri: İngilizceyi yabancı dil olarak öğrenen üniversite öğrencilerine yönelik çıkarımlar

    Full Text Available Oral communication is an interactive process in which an individual alternately takes the roles of speaker and listener. Thus, rather than focusing on each skill separately, these skills should be considered integratedly. In order for students to overcome the burdens in listening and speaking skills, they need to develop communicative competence, especially strategic competence. With reference to speaking, strategic competence points out the ability to know how to keep a conversation going, how to terminate the conversation, and how to clear up communication breakdowns and comprehension problems (Shumin, 1994. Therefore, the aim of this quantitative study is to investigate both speaking and listening strategies (so called “communication strategies” used by EFL students to cope with problems during communication so they can be integrated into language teaching in order to develop students’ strategic competence. Two hundred ninety-one Turkish EFL university students participated in this study. Researchers used the “Communication Strategy Inventory”, a 5 point Likert-type scale developed by Yaman, Irgin and Kavasoglu (2011. The findings of this study revealed that EFL students used negotiation for meaning, compensatory, and getting the gist strategies in communication. It also found that female students used communication strategies more than males and advanced level students.

  4. From board to bedside - training the communication competences of medical students with role plays.

    Role plays and standardized patients are often used in medical education and have proven to be effective tools for enhancing the communication skills of medical students. Most course concepts need additional time and teaching staff, and there are only a few studies about role plays in the preclinical segment. We developed a highly consolidated concept for the curricular course of 2nd-year medical students, including ten role plays about five subjects: anamnesis, shared decision making, prevention, breaking bad news, and so-called "difficult interactions". Before the course, all students were asked about their expectations and attitudes toward the course. After the course, all students rated the course, their individual learning progress, whether their expectations had been fulfilled, and re-evaluated their attitudes. Questionnaires were self-report measures and had a quantitative and a short qualitative section and were analyzed with descriptive statistics. Group differences (sex, age, role played) were evaluated with t tests at a Bonferonni-corrected significance level of p = .03 and the non-parametric U-tests. Implementing this practical course concept is possible without incurring additional costs. This paper not only shows how that can be done but also provides 5 examples of role scripts for different training subjects. The course concept was highly appreciated by the students. More than 75% felt that they had learned important communication techniques and would be better able to handle difficult situations. Playing the doctor's role was felt to be more useful than playing the patient's role. Women admitted a higher degree of shyness in the beginning and gave higher ratings to their learning progress than men. Students' most frequent wish in the qualitative analysis was to be able to play the doctor's role at least once. The students' answers showed a differentiated pattern, thus suggesting that the influence of social desirability was minimal. Practical skills

  10. Using Multiple Methods to teach ASTR 101 students the Path of the Sun and Shadows

    D'Cruz, Noella L.

    2015-01-01

    It seems surprising that non-science major introductory astronomy students find the daily path of the Sun and shadows created by the Sun challenging to learn even though both can be easily observed (provided students do not look directly at the Sun). In order for our students to master the relevant concepts, we have usually used lecture, a lecture tutorial (from Prather, et al.) followed by think-pair-share questions, a planetarium presentation and an animation from the Nebraska Astronomy Applet Project to teach these topics. We cover these topics in a lecture-only, one semester introductory astronomy course at Joliet Junior College. Feedback from our Spring 2014 students indicated that the planetarium presentation was the most helpful in learning the path of the Sun while none of the four teaching methods was helpful when learning about shadows cast by the Sun. Our students did not find the lecture tutorial to be much help even though such tutorials have been proven to promote deep conceptual change. In Fall 2014, we continued to use these four methods, but we modified how we teach both topics so our students could gain more from the tutorial. We hoped our modifications would cause students to have a better overall grasp of the concepts. After our regular lecture, we gave a shorter than usual planetarium presentation on the path of the Sun and we asked students to work through a shadow activity from Project Astro materials. Then students completed the lecture tutorial and some think-pair-share questions. After this, we asked students to predict the Sun's path on certain days of the year and we used the planetarium projector to show them how well their predictions matched up. We ended our coverage of these topics by asking students a few more think-pair-share questions. In our poster, we will present our approach to teaching these topics in Fall 2014, how our Fall 2014 students feel about our teaching strategies and how they fared on related test questions.

  11. Feminist Physics Education: Deconstructed Physics and Students' Multiple Subjectivities

    Science.gov (United States)

    Jammula, Diane Crenshaw

    Physics is one of the least diverse sciences; in the U.S. in 2010, only 21% of bachelors degrees in physics were awarded to women, 2.5% to African Americans, and 4% to Hispanic Americans (AIP, 2012). Though physics education reform efforts supporting interactive engagement have doubled students' learning gains (Hake, 1998), gender and race gaps persist (Brewe et al., 2010; Kost, Pollock, & Finkelstein, 2009). When students' subjectivities align with presentations of physics, they are more likely to develop positive physics identities (Hughes, 2001). However, both traditional and reformed physics classrooms may present physics singularly as abstract, elite, and rational (Carlone, 2004). Drawing from feminist science, I argue that binaries including abstract / concrete, elite / accessible, and rational / emotional are hierarchal and gendered, raced and classed. The words on the left define conventional physics and are associated with middle class white masculinity, while the words on the right are associated with femininity or other, and are often missing or delegitimized in physics education, as are females and minorities. To conceptualize a feminist physics education, I deconstructed these binaries by including the words on the right as part of doing physics. I do not imply that women and men think differently, but that broadening notions of physics may allow a wider range of students to connect with the discipline. I used this conceptual framework to modify a popular reformed physics curriculum called Modeling Instruction (Hestenes, 1987). I taught this curriculum at an urban public college in an introductory physics course for non-science majors. Twenty-three students of diverse gender, race, ethnic, immigrant and class backgrounds enrolled. I conducted an ethnography of the classroom to learn how students negotiate their subjectivities to affiliate with or alienate from their perceptions of physics, and to understand how classroom experiences exacerbate or

  17. Computer Support for Knowledge Management within R&D and the Teaching of Bachelor Students

    Directory of Open Access Journals (Sweden)

    Stefan Svetsky

    2013-01-01

    Full Text Available Abstract—Knowledge plays a key role within research, development and education. One of the major challenges for knowledge management is to select the right knowledge from numerous sources, including know - how of individuals, and to transform it into useful, practicable knowledge. The focus should always be on supporting strategic organisational goals. In this context, from the organisation’s strategic point of view, it is very important to link an institutional knowledge management system with the knowledge management systems of individuals. This paper presents personalised IT - support for knowledge management within industrial R&D and especially for teaching and learning. The support is based on the use of a long term developed in - house software that enables individuals (managers and teachers to process and manage knowledge on their desktop computers in a user friendly way. Within the implementation of “Technology - enhanced learning” at the Faculty of Materials Science and Technology, a pre - programmed work environment called BIKE (Batch Information and Knowledge Editor was developed. However, this desktop environment works also as a teacher’s personalized knowledge management system. It is programmed by the lead author of this paper who is a teacher; therefore the outcomes into teaching bachelor students are implemented directly into the classroom. The paper also presents how such IT - support complements, at a personalized level, the existing organizational knowledge management tool known as the university’s Academic Information System. Some examples from teaching are presented, communication channels (teacher - student forums were also mentioned as a part of the teacher’s knowledge management personalised system. In this case, the BIKE environment is demonstrated as an alternative to learning management systems based on the so called WEB 2.0 technologies.

    2018-04-01

    Industry 4.0 stands for the fourth industrial revolution that is ongoing at present. Industry 4.0 is a terminology generally used in Europe to characterize the integration of production and communication technologies, the so called "smart factory". Lowering costs and efficient in-time production will be possible for low numbers of unique parts, for example by additive manufacturing (3D printing). A significant aspect is also quality and maintainability of these sometimes unique structures and components. NDE has to follow these trends, but introduce the capability of cyber systems into the inspection and maintenance processes. The author initiated in his NDE introductory class student projects where small groups of students had to identify everyday problems that can be solved by NDE techniques and suggest technical solutions based on today's technology. The results where exiting. After discussing the ecosystem and the present situation of NDE as a science, several of these ideas were presented. Let us listen to the ideas and needs of the young generation to re-invent NDE!

    Szymanski, D. W.

    2017-12-01

    Successful collaborations in community science require the participation of non-scientists as advocates for the use of science in addressing complex problems. This is especially true, but particularly difficult, with respect to the wicked problems of sustainability. The complicated, unsolvable, and inherently political nature of challenges like climate change can provoke cynicism and apathy about the use of science. While science education is a critical part of preparing all students to address wicked problems, it is not sufficient. Non-scientists must also learn how to advocate for the role of science in policy solutions. Fortunately, the transdisciplinary nature of sustainability provides a venue for engaging all undergraduates in community science, regardless of major. I describe a model for involving non-science majors in a form of service-learning, where the pursuit of community science becomes a powerful pedagogical tool for civic engagement. Bentley University is one of the few stand-alone business schools in the United States and provides an ideal venue to test this model, given that 95% of Bentley's 4000 undergraduates major in a business discipline. The technology-focused business program is combined with an integrated arts & sciences curriculum and experiential learning opportunities though the nationally recognized Bentley Service-Learning and Civic Engagement Center. In addition to a required general education core that includes the natural sciences, students may opt to complete a second major in liberal studies with thematic concentrations like Earth, Environment, and Global Sustainability. In the course Science in Environmental Policy, students may apply to complete a service-learning project for an additional course credit. The smaller group of students then act as consultants, conducting research for a non-profit organization in the Washington, D.C. area involved in geoscience policy. At the end of the semester, students travel to D.C. and present

    Full Text Available Dear Young Friends,. . . Just as we know the word AMERICA goes back to someone’s name, so we know our “American Language,” as Noah Webster called it, goes back to earlier sources. The most recent of these is of course British English. But we also go back to Old English (before 1066 and even to so-called primitive Germanic, as represented by a translation of the Lord’s Prayer from the original Greek into fourth century Gothic.As a snapshot of our linguistic past, this Gothic translation is quite short (10 lines. But since many students, including me, have over the years learned these 10 lines by heart, I feel a brief look at this early text may stimulate your curiosity, enough so to encourage memorization of, say, the first five lines (only 20 words.Our Gothic text will be followed by a word-by-word treatment that includes phonetic transcriptions of its Gothic pronunciation, its English translation, and some information about its linguistic history. Then we’ll finish with some encouraging words about textual memorization, along with raising a key question for you and your friends to ponder, namely, is Gothic truly a “primitive language”?

    likely to withdraw from the course than occasional or non-SI participants. In biology, no relationship between SI participation, gender, and student ethnic background was found. In chemistry, female students were significantly more likely to attend SI regularly than males. Chemistry minority students had significantly higher representation among occasional SI participants. An important implication involved the use of pedagogical approaches that make lecture classrooms more interactive and encourage student motivation and engagement. This study could be replicated in other science and non-science courses that offer SI sessions. Additional factors in the success of SI programs and student motivation can be added, such as SI leaders' experience and major. Follow-up studies on students who completed the courses included in this study can be conducted to determine whether they reenrolled in other science courses, continued attending SI sessions, and gained self-regulated learning skills.

    Introduction: Informal and formal lifelong learning is essential at university and in the workplace. Apart from classical learning techniques, Web 2.0 tools can be used. It is controversial whether there is a so-called net generation amongst people under 30. Aims: To test the hypothesis that a net generation among students and young veterinarians exists. Methods: An online survey of students and veterinarians was conducted in the German-speaking countries which was advertised via online media and traditional print media. Results: 1780 people took part in the survey. Students and veterinarians have different usage patterns regarding social networks (91.9% vs. 69%) and IM (55.9% vs. 24.5%). All tools were predominantly used passively and in private, to a lesser extent also professionally and for studying. Outlook: The use of Web 2.0 tools is useful, however, teaching information and media skills, preparing codes of conduct for the internet and verification of user generated content is essential.

    The interest on engineering and scientific studies can be raised up even from the early years of academic instructional process. This vocation may be linked to emotions and aptitudes towards technological education. Particularly, students get in touch with these technological issues (namely STEM) during the Compulsory Secondary Education in Spain (12-16 years old).This work presents a preliminary evaluation of how relevant is Gardner's multiple intelligence theory (MIT) in the teaching-learning process within the Technology Lessons. In this sense, MIT was considered as an explanation variable of the emotional response within the different educational parts (so-called syllabus units, SU) in the Technology spanish curriculum. Different intelligence style (IS) will orient the student to a vision of the engineering and technology. This work tries to identify which relationships can be established between IS and specific technology and engineering learning. This research involved up to 135 students were subsequently tested about their predominant (IS) and on the emotions that arouse in them when working with each SU. The results were statistically significant and only those with a Logic-arithmetic or Environmental IS were not affected by the SU.Best teaching and learning practicesare required for encouraging further engineering studies.

    Substance use continues to be major risk behaviour among youth, with consequent physical and/or mental health complications. The current study aimed to establish the prevalence and associated factors of substance use among selected secondary school students in Lagos. This was a cross-sectional and descriptive study among selected secondary school students in Lagos. Permission was obtained from appropriate school authorities; as well as consent from each participant. The WHO Students' Drug Use Questionnaire which had been previously validated in the country was used to obtain the drug use information from the subjects. Analysis of the data was conducted using Epi-info version 5. A total of 402 students were studied - of whom 43.5% (n=175) were males and 56.5% (n=227) females. The mean age was 15.9 years. 83.1% (n=334) lived with their parents, 7.6% (n=31) with their relatives and 7.2% (n=29) with friends. The commonest substances used by the subjects were caffeine (kolanut and coffee), mild analgesics (paracetamol and aspirin) and the antimalarials, most especially chloroquine with lifetime use prevalence rates of 85.7%, 73.8% and 65.7% respectively. Generally, the prevalence rates for lifetime use of the substances varied from 3.8% (n=14) for Heroin and Cocaine to 85.7% (n=344) for psychostimulants; and for current use varying from 2% (n=8) to 56.5% (n=213). For the so called "gateway drugs": alcohol and tobacco, their lifetime use prevalence rates were 9.2% (n=34) and 5.2% (n=19) while the lifetime use prevalence rate for cannabis was 4.4% (n=16). In terms of gender, the prevalence rates for males were generally higher than for their female counterparts except for antibiotics, analgesics, heroin and cocaine. Reasons for using substances included relief from stress, 43.5% (n=175), self medication to treat illness, 23.8% (n=96), and to stay awake at night to study, 14.9% (n=60). Substance use was found to be prevalent among students in this study involving over

    The field of astrobiology, through its breadth of scope and high level of public interest, offers a unique prospect for introductory science curricula, particularly at the undergraduate level. Traditional university-level science instruction consists of lectures and accompanying lab courses that are highly scripted to emphasize correct replication of results rather than inquiry-driven exploration. These methodologies give students the impression that science is an authoritative list of abstract concepts and experimental results requiring memorization, rather than a methodology for narrowing uncertainties in our knowledge. Additionally, this particular class structure does not take advantage of many new and emerging online multimedia technologies. To address the shortcomings of current pedagogical approaches, we adapted the Arizona State University introductory-level course "Habitable Worlds" for online delivery in the fall semester of 2011. This course is built around the Drake Equation, which allows us to introduce non-science students to the basics of scientific thought and methodology while exploring disciplines as diverse as astronomy, geology, biology, and sustainability in an integrated manner. The online version of this course is structured around a habitable-worlds-hunting quest, where each student is provided with an individualized universe and tasked with finding scientifically realistic computer-generated inhabited planets around realistic stars. In order to successfully complete this mission, students work their way through the course curriculum via interactive exercises that focus on the discovery of basic scientific concepts followed by the mathematics and models that explain them, hence inverting the lecture-lab paradigm. The "Habitable Worlds" course is built on the Adaptive eLearning Platform (AeLP), an innovative educational technology that provides a "tutor over the shoulder" learning experience for students. Our focus is on engaging students

    will be the typical learning environment for physics students in the future. However, the details of this change should be based on a better understanding of the learning process in a students' lab. A deeper insight is given by the contribution of Claudia von Aufschnaiter and Stefan von Aufschnaiter in 'University students' activities, thinking and learning during laboratory work'. A second important alteration has taken place in physics education during the last decade. The so-called new media have changed the world of learning and teaching to an unprecedented extent. Learning with new media is often much more related to physics labwork than to traditional lectures or seminars (e.g. small learning groups, problem based learning, a high level of interactivity). We need to take these new tools into consideration as suitable amendment (blended learning) or substitution (e-learning, distance learning) of labwork courses. The developments with presumably the highest impact on physics education are modelling tools, interactive screen experiments and remote labs. Under 'modelling tools', all computer programs are summarized which enable the simulation of a physical process based on an explicit or implicit given formula. Many commercial program packages are available. The application of modelling tools in labwork courses permits a tight binding of theory and experiment. This is particularly valid and necessary in the case of project work. An interactive screen experiment (ISE) is a computer assisted representation of a physical experiment. When watching a video clip of an experiment students are forced to be passive observers. In the case of an ISE they can manipulate the setup on the screen with the help of a hand-like mouse pointer and the computer will show the appropriate result. The ISE consists of a large number of digital photos taken from the real experiment. From an epistemological point of view an ISE has the character of an experiment and can be used to discover or

    Sowell, Mitzie Leigh

    Recent declines in science literacy and inadequate numbers of individuals entering science careers has heightened the importance of determining why students major in science or do not major in science and then choose a science-related career. Therefore, the purpose of this study was to examine the relationship between parental influences and student career choices of both males and females majoring and not majoring in science. This study specifically examined the constructs of parental occupation, parental involvement, and parental education levels. Aspects indicated by the participants as being influencers were also examined. In addition, differences between males and females were examined. A total of 282 students participated in the study; 122 were science majors and 160 were non-science majors. The data was collected through the use of a student information survey and the Modified Fennema-Sherman Attitude Scale. The findings suggest that students indicated the desire to help others, peers, salary, and skills as influencing their career choice. In regard to the various parental influences, mother's occupation was the only construct found as a statistically significant influencer on a student's decision to major in science. The results of this study can help educators, administrators, and policy makers understand what influences students to pursue science-related careers and possibly increase the number of students entering science-related careers. The results of the study specifically provide information that may prove useful to administrators and educators in the health science fields, particularly nursing fields. The findings provide insight into why students may choose to become nurses.

    The astronomy education community has tacitly assumed that learning astronomy is a conceptual domain resting upon spatial thinking skills. As a first step to formally identify an empirical relationship, undergraduate students in a non-major introductory astronomy survey class at a mediumsized, Ph.D. granting, mid-western US university were given pre- and post-astronomy conceptual diagnostics and spatial reasoning diagnostics, Instruments used were the "Test Of Astronomy Standards" and "What Do You Know?" Using only fully matched data for analysis, our sample consisted of 86 undergraduate non-science majors. Students' normalized gains for astronomy surveys were low at .26 and .13 respectively. Students' spatial thinking was measured using an instrument designed specifically for this study. Correlations between the astronomy instruments' pre- to post-course gain scores and the spatial assessment instrument show moderate to strong relationships suggesting the relationship between spatial reasoning and astronomy ability can explain about 25% of the variation in student achievement. La comunidad de educación en astronomía ha supuesto de forma tácita que el aprendizaje de la astronomía consiste en un dominio conceptual fundamentado en el razonamiento espacial. Como un primer paso para identificar formalmente una relación empírica entre estas dos cosas, utilizamos como muestra los estudantes de graduación de carreras no científicas de un curso experimental en una universidad norteamericana del medioeste de porte mediano con programa de Doctorado em curso, en el cual estos estudiantes se sometieron a un diagnóstico de razonamiento espacial y conceptos astronómicos antes e después del mismo. Las herramientas utilizadas fueron el Test Of Astronomy Standards (TOAST) y el cuestionario What do you know? Utilizando solo los datos completamente consistentes para este análisis, nuestra muestra consistió en 86 estudantes de graduación. Las mejoras, depués de

    Full Text Available The perceived contribution of science education online course to pre-service students (N=121 from diverse backgrounds - students with learning disabilities (25 LD students, 28 excellent students and 68 average students is presented in this five years research. During the online course students were asked to choose a scientific subject; to map it and to plan teaching activities; to carry out the proposed activities with students in a classroom experience; and to reflect the process. The assumption was that adapting the online course by using information and communication technology following formative assessment will improve students' self-learning ability as well as broaden their science knowledge, their lab performance and teaching skills. Data were collected using quantitative and qualitative tools including: pre and post questionnaires and nine (three students from each group depth interviews upon completion of the course. Findings, based on students` perceived evaluation, pinpointed on the advantages of the online course for students of the three groups. LD students’ achievements were not inferior to those of their peers, excellent students and average students. Yet, it carefully reports on a slight but explicitly marginal perceived evaluation of the LD students in comparison to excellent students and average students regarding: forum participation, authentic task and water lab performance. The article discusses the affordance of the online course via additional features that can be grouped into two categories: knowledge construction and flexibility in time, interaction and knowledge. Further research is suggested to extend the current study by examine the effect of other courses and different contents and by considering various evaluation methods of online courses, such as: observation, the think aloud, text and tasks analysis, and reflection.

  14. Kinesthetic Astronomy: Significant Upgrades to the Sky Time Lesson that Support Student Learning

    Science.gov (United States)

    Morrow, C. A.; Zawaski, M.

    2004-12-01

    This paper will report on a significant upgrade to the first in a series of innovative, experiential lessons we call Kinesthetic Astronomy. The Sky Time lesson reconnects students with the astronomical meaning of the day, year, and seasons. Like all Kinesthetic Astronomy lessons, it teaches basic astronomical concepts through choreographed bodily movements and positions that provide educational sensory experiences. They are intended for sixth graders up through adult learners in both formal and informal educational settings. They emphasize astronomical concepts and phenomenon that people can readily encounter in their "everyday" lives such as time, seasons, and sky motions of the Sun, Moon, stars, and planets. Kinesthetic Astronomy lesson plans are fully aligned with national science education standards, both in content and instructional practice. Our lessons offer a complete learning cycle with written assessment opportunities now embedded throughout the lesson. We have substantially strengthened the written assessment options for the Sky Time lesson to help students translate their kinesthetic and visual learning into the verbal-linguistic and mathematical-logical realms of expression. Field testing with non-science undergraduates, middle school science teachers and students, Junior Girl Scouts, museum education staff, and outdoor educators has been providing evidence that Kinesthetic Astronomy techniques allow learners to achieve a good grasp of concepts that are much more difficult to learn in more conventional ways such as via textbooks or even computer animation. Field testing of the Sky Time lesson has also led us to significant changes from the previous version to support student learning. We will report on the nature of these changes.

    Winner D. Chawinga

    2016-05-01

    Full Text Available Background: Over the years, advancements in Internet technologies have led to the emergence of new technologies such as Web 2.0, which have taken various sectors including higher education by storm. Web 2.0 technologies are slowly but surely penetrating higher education in developing countries with much hype, according to the literature. This justifies the need for original research that aims at demystifying the application and exploiting the promises that come along with these so-called versatile technologies. Objectives: The specific objectives of the study were to ascertain students’ awareness of and familiarity with Web 2.0 technologies, to determine the purposes for which students use Web 2.0 technologies, and to identify the factors that affect students’ use or non-use of Web 2.0 technologies. Method: A mixed-methods approach was adopted. Firstly, a questionnaire was sent to 186 students; secondly, the curricula of the two departments in the Faculty of Information Science and Communication (ISC were analysed; finally, follow-up interviews were conducted with seven lecturers in the Faculty of ISC. Results: The study found that students use Web 2.0 technologies to search for information, to communicate with lecturers, to submit assignments and to communicate with friends on academic work. Wikipedia, WhatsApp, Google Apps and YouTube are the Web 2.0 technologies most used by students. Poor bandwidth (Internet connection coupled with the absence of Wi-Fi (wireless Internet connection prevents the successful adoption of Web 2.0 by students. Conclusion: Web 2.0 can have a profound impact on undergraduate students and lecturers in teaching and learning. The research results indicated a high awareness of a wide range of Web 2.0 technologies, with social networks being the commonly used one. There is a need for more training to increase awareness of and familiarity with new Web 2.0 technologies. The problem of poor bandwidth needs to be

    Full Text Available Customer satisfaction has long been recognized as a central concept of all business activities. Satisfaction can serve as an indicator of success of the company, both in the past and present, as well as an indicator of future performance. High quality service to students is a prerequisite of maintaining competitiveness in the market of higher education. A relationship that is created between the expectations of students and their satisfaction with the quality of service that provides educational institution plays an important role in shaping the reputation of academic institutions. Academic institutions are becoming aware of the importance of student satisfaction, because satisfaction positively influences their decision to continue their education at this institution, and the positive word of mouth that will attract prospective students. Satisfaction will affect student motivation, and therefore their performance. This paper provides insight into the marketing aspects of customer satisfaction, primarily insight into the satisfaction of students in the educational sector. The aim is to establish the influence of satisfaction various factors related to the university and higher education to the satisfaction of student life, and does student life satisfaction affect the overall happiness and student performance. The research was conducted on the student population of the University of Split, on a sample of 191 respondents. The research was conducted with the help of online survey questionnaire. The claim that student’s satisfactions with housing affect the satisfaction with the quality of student life is rejected. The results confirmed that the student’s satisfaction with university contents, university bodies and services, teaching, teaching methods and academic reputation affects the satisfaction of student life and student life satisfaction affect the student performance.

    Full Text Available Mathematics, as a body of scientific knowledge, includes not only a set of concepts and theories described in books and scientific journals but a procedural knowledge used for solving problems and proving the resulting solution. There is a tool for proving solutions, the so-called mathematical proof, which is worth to be included in the educational process. To complete the study herein described a random stratified sample was selected and given a test demanding to explain the answers given. However, high school students (15-18 years old do not rely on the use of the known proof scheme. For that reason, a diagnostic study was carried out at the Autonomous University of Querétaro (UAQ in order to identify the strategies the students are currently following and finding ways to teach such mathematical proof scheme. The findings are a description of individual students’ argumentative practices and the identification and grouping of the most frequently used proof scheme.

    Due to recent changes in the medical licencing act as well as to the introduction of a new model-course programme for medical studies, careers in medicine have become increasingly more attractive. However, there is still a dramatic shortage in younger generation physicians, especially within the surgical fields. The goal of this cross-sectional study was the gender-specific assessment of the ideal career wishes of students during medical school, with a focus being placed in orthopaedic trauma surgery. During the winter semester of 2010/2011 an online questionnaire (www.surveymonkey.com) was created for students enrolled in their 3rd to 12th semester (n=887). The questionnaire consisted of 50 questions [Likert scale (LS); 5 = agree, 1 = disagree] along with 10 free response questions. The scope of these questions ranged from personal career goals, within the context of their learning environment, to general life goals and planning. With regard to career choice, a differentiation was made between students' ideal career choices/subjects (IS), which were based solely on personal affinity, and so-called reality-based subjects (RS), which students considered more practical and to which they were more likely to apply in the future. The response rate was 36,4% (n=323, 23,4 years, 6.3 semesters, 226 [70.0%] female [f] and 97 [30.0%] male [m]). A total of 206 students (63.8%; m=55.7% vs. f=66.7%; p=0.047) were able to pinpoint an IS, this percentage increased with increasing semester number (p=0.048). Overall, 29.1% of students indicated that their IS lay in the field of orthopaedic trauma, while 20.0% of men and 19.1% of women saw it as a realistic career path (RS). Throughout the course of their studies, from the 3rd semester to their practical year, a declining tendency was observed regarding the agreement between ideal and realistic career paths. Particularly evident was a decreasing interest in the field of orthopaedic trauma, beginning around the 9th semester and

    Full Text Available Introduction: the article is devoted to such an actual today issue as increasing of motivation of students learning foreign languages in non-language faculties of a contemporary university. The authors identify the main reasons causing the low level of language preparation among students of non-linguistic directions of preparation, which include – lack of motivation for the implementation of utterance (dominated by a strong belief that in real life it is not useful; small vocabulary; poor knowledge (or ignorance of grammar of the language being studied; the fear of making a mistake (“psycholo gical barrier”. Materials and Methods: the methodological basis of the research are scientific methods such as observation and experiment. In addition, the authors used some other methods such as study of students’ performance (written, examinations, tests, essays, dictations, summaries, etc.; method of pedagogical experiment; modeling. Results: in order to change this situation, the authors suggest to activate the teaching and speech activity of students at two levels: 1 motivation and impelling (to form among students sustained motive (need to speak and 2 tentatively and research (to train the ability to independently select and apply language and speech means appropriated to conditions and social environment. One must skillfully combine both traditional and innovative approaches and methods in the teaching of foreign languages, among which the authors identify a number of basic: the so-called gambling technology (business and role-playing games, information and communication technologies (presentations, projects, online tutorials, webinars, Internet communication with foreign counterparts, meetings and discussions with native speakers, participate in competitions and others. Their alternation on pairs will maintain the attention and interest of students at a high level. Discussion and Conclusions: it is noted that a key role in this process is

  7. Examining student conceptions of the nature of science from two project-based classrooms

    Science.gov (United States)

    Moss, David M.

    The purpose of this research was to develop descriptive accounts of precollege students' conceptions of the nature of science from two project-based classrooms, and track those conceptions over the course of an academic year. A model of the nature of science was developed and served as the criterion by which students' beliefs were evaluated. The model distinguishes between two major categories of science, the nature of the scientific enterprise and the nature of scientific knowledge. Five students were selected from each class and interviewed individually for 30-45 minutes each, six times over the year. Data from semi-structured, formal interviewing consisted of audio-recorded interviews which were transcribed verbatim. All passages were coded using codes which corresponded to the premises of the model of the nature of science. Passages in the transcripts were interpreted to develop a summary of the students' conceptions over the year. Qualitative methodologies, especially formal interviewing in conjunction with participant observation, were effective for uncovering students' conceptions of the nature of science, adding to the knowledge base in this field. The research design of the current study was a significant factor in explaining the inconsistencies seen between findings from this study and the literature. This study finds that participants at both classroom sites held fully formed conceptions of the nature of science for approximately 40 percent of the premises across the model. For two-thirds of the elements which comprise the premises, participants held full understandings. Participants held more complete understandings of the nature of scientific knowledge than the nature of the scientific enterprise. Most participants had difficulty distinguishing between science and non-science and held poor understandings of the role of questions in science. Students' beliefs generally remained unchanged over the year. When their conceptions did evolve, project

    Many times there are no ideal answers to any of the interpersonal conflicts addressed. Often the solutions to these situations may depend on an individual's characteristics or personality. By analyzing the situation and the supervisor's attitude and then changing his or her way of responding to that situation, however, the student may improve his or her problem-solving skills. The student can modify the strategies taught in these seminars to suit his or her individual needs and particular situations. A seminar like this can provide students, and thus future therapists and student supervisors, with a solid background in dealing more tactfully with a variety of conflict-ridden situations in the workplace.

    After a number of high-profile incidents and national reports, it has become clear that all health professionals and all medical students must be able to raise concerns about a colleague's behavior if this behavior puts patients, colleagues, or themselves at risk.Detailed evidence from medical students about their confidence to raise concerns is limited, together with examples of barriers, which impair their ability to do so. We describe a questionnaire survey of medical students in a single-center, examining self-reported confidence about raising concerns in a number of possible scenarios. Thematic analysis was applied to comments about barriers identified.Although 80% of respondents felt confident to report a patient safety issue, students were less confident around issues of probity, attitude, and conduct. This needs to be addressed to create clear mechanisms to raise concerns, as well as support for students during the process.

    2010-09-01

    Homophobia is defined as a general negative attitude towards homosexual persons, with implications on public health. This fact has been less investigated among nursing students. The objective of this review was to learn about the prevalence of homophobia and its associated variables among nursing students. A systematic review was performed on original articles published in EBSCO, Imbiomed, LILACS, MEDLINE, Ovid, and ProQuest, including articles published between 1998 and 2008 in English, Portuguese and Spanish. Keywords used were homophobia, homosexuality, and nursing students. Descriptive analysis was performed. Eight studies were analyzed. The incidence of homophobia in nursing students is between 7% and 16%. Homophobia is more common among males and religious conservatism people. Homophobia is quite frequent in nursing students. This negative attitude toward homosexuality may affect services and care giving by nursing professions and could have negative implications in nursing practice.

    Sustainability issues are increasingly important in engineering work all over the world. This article explores systematic differences in self-assessed competencies, interests, importance, engagement and practices of newly enrolled engineering students in Denmark in relation to environmental and non-environmental sustainability issues. The empirical base of the article is a nation-wide, web-based survey sent to all newly enrolled engineering students in Denmark commencing their education in the fall term 2010. The response rate was 46%. The survey focused on a variety of different aspects of what can be conceived as sustainability. By means of cluster analysis, three engineering student approaches to sustainability are identified and described. The article provides knowledge on the different prerequisites of engineering students in relation to the role of sustainability in engineering. This information is important input to educators trying to target new engineering students and contribute to the provision of engineers equipped to meet sustainability challenges.

    2014-08-01

    Full Text Available Studies on the impact of health behaviors on morbidity often focus on the limited impact of a single behavior or a limited group of behaviors. In this study, we examine college student behaviors and investigate the link of these behaviors with a 2-week illness profile. Through self-reported surveys, we measure acute illness and a general illness burden, a cumulative measure of major and minor ailments. We explore how daily routines correlate with these illness measures. Eighty-four students from a random sample of 90 students attending a small liberal arts school completed the survey for a response rate of 93%. Living arrangements, exercise, sleep patterns, eating preferences and habits, and “social” behaviors were all significantly associated with illness burden. Students living in “singles” and those who got regular exercise and an average of 7 hr of sleep per night reported less illness. Most interesting is the effect of social behaviors. Students who greet others with a handshake reported higher illness rates, as did students who share food and/or drinks. While we can conceptualize why these behaviors would lead to a greater illness burden, students who engaged more frequently in these behaviors also reported being “happier.” In trying to reduce illness among college students, we might suggest less handshaking and food and beverage sharing, but these actions are ways in which college students express and maintain friendships. College administrators are challenged to discover ways to reduce illness while maintaining the positive aspects of local student culture. This study begins to explore some ways to balance health and camaraderie.

  16. Science Communication versus Science Education: The Graduate Student Scientist as a K-12 Classroom Resource

    Science.gov (United States)

    Strauss, Jeff; Shope, Richard E., III; Terebey, Susan

    2005-01-01

    Science literacy is a major goal of science educational reform (NRC, 1996; AAAS, 1998; NCLB Act, 2001). Some believe that teaching science only requires pedagogical content knowledge (PCK). Others believe doing science requires knowledge of the methodologies of scientific inquiry (NRC, 1996). With these two mindsets, the challenge for science educators is to create models that bring the two together. The common ground between those who teach science and those who do science is science communication, an interactive process that galvanizes dialogue among scientists, teachers, and learners in a rich ambience of mutual respect and a common, inclusive language of discourse . The dialogue between science and non-science is reflected in the polarization that separates those who do science and those who teach science, especially as it plays out everyday in the science classroom. You may be thinking, why is this important? It is vital because, although not all science learners become scientists, all K-12 students are expected to acquire science literacy, especially with the implementation of the No Child Left Behind Act of 2001 (NCLB). Students are expected to acquire the ability to follow the discourse of science as well as connect the world of science to the context of their everyday life if they plan on moving to the next grade level, and in some states, to graduate from high school. This paper posits that science communication is highly effective in providing the missing link for K-12 students cognition in science and their attainment of science literacy. This paper will focus on the "Science For Our Schools" (SFOS) model implemented at California State Univetsity, Los Angeles (CSULA) as a project of the National Science Foundation s GK-12 program, (NSF 2001) which has been a huge success in bridging the gap between those who "know" science and those who "teach" science. The SFOS model makes clear the distinctions that identify science, science communication, science

No tipo B, a primeira etapa de unificação das colaterais intra ou extra-hilares foi realizada em 6 casos, sem óbitos; em 2, a segunda etapa da correção total foi realizada, com um óbito. No tipo C, 2 pacientes foram operados; 1 em três etapas; a primeira constou de construção de segmento arterial intermediário entre as artérias lobares e o BT; a segunda compreendeu unificação das colaterais contralaterais e a terceira, restabelecimento da continuidade ventrículo direito - circulação pulmonar; o paciente teve boa evolução. No segundo caso, a correção foi realizada após somente uma intervenção prévia. A evolução foi satisfatória. Estudos hemodinâmicos seriados foram realizados em 32 pacientes. As técnicas propostas permitem obter condições para correção total com adequada relação pós-operatória das pressões ventrículo direito - ventrículo esquerdo.Fourty-two patients with pulmonary atresia and interventricular septal defect were submited to a partial or total correction, between January 1975 and October 1986, with a range of 2 months to 18 years of age. Three groups were identified: Group A: 34 patients with all bronco-pulmonary segments connected to pulmonary arteries (PA; Group B: 6 patients with some of the bronco-pulmonary segments connected to PA's; Group C: 2 patients with all bronco-pulmonary segments connected to systemic pulmonary collaterals. One to three stages were utilized to perform the proper correction. In Group A 17 were treated in one stage, with 3 deaths; 9 were submitted to a first stage where the pulmonary arteries were reconstructed with an additional Blalock-Taussig (BT shunt, with 1 death. In two of them a second stage for total correction was performed, with no death. In the remaining 8 patients the collateral circulation was ligated and a BT shunt performed, with 1 hospital death. In Group B the first stage joining the intra or extra-pulmonary collaterals was obtained in 6 cases, without death. In two of them a total correction was performed, with 1 death. In group C a three stage operation was done in 1 patient. In the first stage an intermediate arterial segment was constructed between the lobar arteries and the BT shunt. In the second stage the contra-lateral collaterals were joined. The third stage was the establishment of the continuity between the right ventricle and the reconstructed pulmonary circulation with a good result. In the other patient of this group, until now, only the first stage was done. Serial hemodynamic studies were carried out in 32 patients. These proposed techniques demonstrate the possibility of total correction with appropriate righ-to-left ventricular pressure relation.

    The conversion of biomass with low quality into biochar through pyrolysis or hydro-thermal carbonization is suitable to substitute lignite and hard coal as a fuel and thereby improve the carbon footprint of a firing plant: Additionally there is the possibility to apply biochar to fields. Carbon compounds, stabilized by the carbonization process, could simultaneously increase crop yields and sequester carbon for mid- and long term. This paper compares the two processes pyrolysis and hydrothermal carbonization regarding input-material, process-parameters, product-properties and possible applications for each product. The aim is to give an overview which process with given parameters leads to which final product and application. (orig.)

    Full Text Available The purpose of this study was to (a identify potential benefits for students with disabilities taking part in a physical activity program with same-age typical peers on a Midwest university campus, and (b to determine if the program impacted the students with disabilities empowerment. Empowerment theory was used to determine how transition students’ attitudes change over the course of the semester while participating in a workout buddy program with same-age college peers. The program was structured to provide a sense of empowerment to students to make their own decisions and learn for themselves so they don’t feel a lack of power in their lives. This study implemented elements of a quantitative design but a majority utilized a qualitative design based on the assumptions of the Interpretivist paradigm. The quantitative design elements focused on the analysis of two questionnaires: Sports Questionnaire; and The Perceived Control Scale Questionnaire. The analysis of the focus group data revealed the following themes as positive effects of the intervention; positive effect on empowerment, how happy the program made the students, what benefits the students gained from the program, the student’s familiarity with university students, and the environment and lastly the students ability to ask for assistance when need. Findings from the study determined that the empowerment of the students with disabilities was impacted while participating in the program. In general, the findings of gaining empowerment were similar to previous studies in that students with disabilities are able to gain empowerment from participation in fitness and recreation programs. The researcher noted during focus groups that some of the BOBW students were not confident in starting conversations with their university. Although the BOBW students felt a sense of losing empowerment with this specific instance, there was an overall positive impact on the BOBW students

    Pahud, D. M.; Niembro, T.

    2014-12-01

    The SHINE workshop is an annual meeting of solar and heliospheric scientists which, in addition to aiming to improve understanding of solar disturbances and their propagation to, and effect, on the Earth (shinecon.org), is dedicated to actively supporting students. This dedication is substantiated in part through the National Science Foundation (NSF) providing funding for student attendance to the workshop, which enables student participation. Another example of SHINE's commitment to its student members is the incorporation of a Student Day prior to the workshop since 2003, entirely organized and run by two student representatives. While there are variations in format from year to year, Student Day consists of tutorials and research talks exclusively by student volunteers to an audience of only students. The day is intended to provide a low-stress environment for students to learn about the various topics addressed during the workshop, to ask questions freely, and to engage in scientific discussion with other students which hopefully is a catalyst for collaboration. As a result of positive experiences, over the past decade student attendance and participation in the workshop have increased. At the SHINE 2014 workshop, nearly a third of attendees were students. SHINE student visibility has increased over the years, with student posters being advertised at breakfast, inclusion of a student day summary by the student representatives during a plenary session, and continued support from the steering committee. Students are also promoting a broader impact of SHINE sciences via increased social media presence. From a student representative's perspective, SHINE has built and fostered a healthy student community and encourages students to engage in shaping the future of the field.

    2003-12-01

    In the Fall semester of 2003, Northern Arizona University will introduce the GeoWall to its introductory geology courses. This presents an opportunity to assess the impact of this new technology on students' understanding of basic topographic concepts and the spatial relationships between geology, topography, and hydrology on a field trip. Introductory Geology fulfills the Lab Science component of the Liberal Studies Program at Northern Arizona University. The class is open to all Northern Arizona University students, and is most commonly taken by non-science majors. In this class students learn to: locate their position using maps, identify common minerals and rocks, recognize the relationship between geology and geomorphology, visualize how rocks exposed at the surface continue into the subsurface, and to draw conclusions about possible geologic hazards in different settings. In this study we will report how a GeoWall 3D visualization technology was used in a field study of a graben south of Flagstaff. The goal of the field exercise is to improve students' ability to synthesize data collected at field stops into a conceptual model of the graben, linking geology, geomorphology and hydrology. We plan to present a quantitative assessment of the GeoWall learning objectives from data collected from a paired test and control group of students. Teaching assistants (TAs) with two or more lab classes have been identified; these TAs will participate in both GeoWall and non-GeoWall lab exercises. The GeoWall use will occur outside of normal lab hours to avoid disrupting the lab schedule during the eighth week of lab. This field preparation exercise includes a 3D visualization of the Lake Mary graben rendered with the ROMA software. The following week, all students attend the graben field trip; immediately following the trip, students will interviewed about their gain in understanding of the geologic features illustrated during the field trip.

    2017-07-01

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

    Culver, Jennifer

    The purpose of this study was to examine the qualities of support, relatedness, and negative interaction within parent-child and teacher-student relationships and their association with cognitive, psychological, and behavioral engagement. Additionally, this study explored the contributions of cognitive and psychological engagement on behavioral engagement. The role of gender, grade, and ethnicity on relationship quality and engagement was also considered. Participants (n=311) were students in grades three through five from a suburban school district in southeastern Michigan. Perceptions of teacher-student relationship quality varied by grade level. In general, younger students reported greater teacher support and relatedness in comparison to older students. Conversely, older students perceived greater conflict within the teacher-student relationship. Student engagement also varied by grade level, with younger students reporting greater engagement than older students. Ethnicity also contributed to variance in student engagement, with African American students reporting significantly more engagement than Caucasian or Multiracial students. Teacher-student relationship quality was a significant predictor of student engagement, even after controlling for student characteristics and parent-child relationship variables. Results of path analysis revealed that cognitive and psychological engagement contributed significantly to behavioral engagement.

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

  18. GENDER CONFLICTS OF STUDENTS

    Full Text Available Actuality of work. Student age has the most favourable conditions for psychological, biological and social development; however, there are reasons why such natural advantages over other social groups can be completely or partially levelled. One of them is the presence of conflicts in the life of a student, a special group, among which there are women. The causes of the emergence of gender conflicts in individual social groups and the strategies for their solution have not been sufficiently explored and require further study and, therefore, are relevant. Purpose of the article is to investigate the causes of gender conflicts among students as a separate social group and to develop measures to address them and prevent them. Methodology. The research conducted in the work is based on the analysis and generalization of the causes of the emergence of gender conflicts among students, the identification of the main sources of information that form the consciousness of children and adolescents, and also influence their attitude to gender equality. Originality. The nature of gender conflicts has been quite effectively studied for a long time. However, the scope of research is limited to the most numerous social groups, such as the family, labour collective, political and public organizations, etc. Being a dynamic and socio-demographic formation, the students perform an important function in society – it takes a direct part in the transformation of all spheres of the life activity of the society. Based on the study of the objective conditions of the social environment with certain models of socialization that form the consciousness of students from early childhood, a three-component system of influence was first proposed, which is aimed at overcoming gender inequality and preventing gender conflicts among students. At the same time, the interaction of the components of the system will allow to minimize the gender inequality index in our country

    The SPHERES facility is a set of three free-flying satellites launched in 2006. In addition to scientists and engineering, middle- and high-school students program the SPHERES during the annual Zero Robotics programming competition. Zero Robotics conducts virtual competitions via simulator and on SPHERES aboard the ISS, with students doing the programming. A web interface allows teams to submit code, receive results, collaborate, and compete in simulator-based initial rounds and semi-final rounds. The final round of each competition is conducted with SPHERES aboard the ISS. At the end of 2017 a new robotic platform called Astrobee will launch, providing new game elements and new ground support for even more student interaction.

This is the main question in Bruce Macfarlane’s book Freedom to learn - The Threat to Student Academic Freedom and Why it Needs...... to be Reclaimed (2017). In eighth well-written chapters, Macfarlane explores an often-overlooked paradox in higher education teaching and learning: The idea of the student centered learning, deriving from humanist psychology and progressive pedagogy, has been hijacked by increased and continuous demands of bodily......, cognitive and emotional performance that restricts students’ freedom to develop as autonomous adults.

    Fostering and maintaining students' interest in science is an important aspect of improving science learning. The focus of this paper is to listen to and reflect on students' voices regarding the sources of motivation for science subjects among students in community secondary schools with contextual challenges in Tanzania. We conducted a group-interview study of 46 Form 3 and Form 4 Tanzanian secondary school students. The study findings reveal that the major contextual challenges to student motivation for science in the studied schools are limited resources and students' insufficient competence in the language of instruction. Our results also reveal ways to enhance student motivation for science in schools with contextual challenges; these techniques include the use of questioning techniques and discourse, students' investigations and practical work using locally available materials, study tours, more integration of classroom science into students' daily lives and the use of real-life examples in science teaching. Also we noted that students' contemporary life, culture and familiar language can be utilised as a useful resource in facilitating meaningful learning in science in the school. Students suggested that, to make science interesting to a majority of students in a Tanzanian context, science education needs to be inclusive of students' experiences, culture and contemporary daily lives. Also, science teaching and learning in the classroom need to involve learners' voices.

  4. Students' understandings of electrochemistry

    Science.gov (United States)

    O'Grady-Morris, Kathryn

    Electrochemistry is considered by students to be a difficult topic in chemistry. This research was a mixed methods study guided by the research question: At the end of a unit of study, what are students' understandings of electrochemistry? The framework of analysis used for the qualitative and quantitative data collected in this study was comprised of three categories: types of knowledge used in problem solving, levels of representation of knowledge in chemistry (macroscopic, symbolic, and particulate), and alternative conceptions. Although individually each of the three categories has been reported in previous studies, the contribution of this study is the inter-relationships among them. Semi-structured, task-based interviews were conducted while students were setting up and operating electrochemical cells in the laboratory, and a two-tiered, multiple-choice diagnostic instrument was designed to identify alternative conceptions that students held at the end of the unit. For familiar problems, those involving routine voltaic cells, students used a working-forwards problem-solving strategy, two or three levels of representation of knowledge during explanations, scored higher on both procedural and conceptual knowledge questions in the diagnostic instrument, and held fewer alternative conceptions related to the operation of these cells. For less familiar problems, those involving non-routine voltaic cells and electrolytic cells, students approached problem-solving with procedural knowledge, used only one level of representation of knowledge when explaining the operation of these cells, scored higher on procedural knowledge than conceptual knowledge questions in the diagnostic instrument, and held a greater number of alternative conceptions. Decision routines that involved memorized formulas and procedures were used to solve both quantitative and qualitative problems and the main source of alternative conceptions in this study was the overgeneralization of theory

    we know about climate change, 2) in what ways the curriculum and the teaching practices support this type of student talk, 3) how the quantity and quality of student talk leads to a greater understanding of both WHAT we know about climate change and HOW we know it. Through systematic classroom observations, we documented student engagement and interactions. In-depth analysis of video recordings revealed more about the nature of these interactions and how students talk with each other and the teacher about how we know. From pre- and post-tests of 756 middle school and high school students in 30 classrooms, we found statistically significant differences (t=-19.78, p<0.001) between total scores on the pre-test (68.1 % correct) and post-test (79.1% correct). At the classroom level, these data served to create portraits of classrooms where "how do we know talk" was prevalent and where teaching practices supported such talk. In these classrooms, students showed significant gains in both content knowledge and analytic skills. We argue that these students became climate literate and thus better equipped to critically distinguish between climate science and non-science they might encounter via the internet, the media, or other sources.

    Three sixteen-year-old students from the International School of Geneva, La Chataigneraie have spent a week finding out about the life of a theoretical physicist at CERN. Student Peter Bishop at the blackboard with Robert Fleischer of Theory Division. Peter Bishop, Sam Schoenholz and Alexander Hultin spent the time with the Theory Unit of the Physics department. The visit was at the suggestion of the students themselves, who are required to undertake work experience at an organization, gaining insights into professional life, as part of their studies. After an introduction to CERN at Microcosm, each student had the opportunity to learn about physics at a level well beyond their current academic training. They were mentored by theoretical physicists who introduced them to the basics of particle physics, discussing physics in general as well as topics such as predicting the mass of the Higgs boson and cosmology. A visit to CMS, guided by Ariane Frey, proved very impressive, but the working conditions of physi...

  18. An investigation of the relationships between junior high school students' (8th and 9th grades) background variables and structure of knowledge recall of biological content

    Demetrius, Olive Joyce

    The purpose of this study was to examine the relationships between Junior High School students' (8th and 9th grades) background variables (e.g. cognitive factors, prior knowledge, preference for science versus non-science activities, formal and informal activities) and structure of information recall of biological content. In addition, this study will illustrate how flow maps, a graphic display, designed to represent the sequential flow and cross linkage of ideas in information recalled by the learner can be used as a tool for analyzing science learning data. The participants (46 junior high school students) were taught a lesson on the human digestive system during which they were shown a model of the human torso. Their pattern of information recall was determined by using an interview technique to elicit their understanding of the functional anatomy of the human digestive system. The taped responses were later transcribed for construction of the flow map. The interview was also used to assess knowledge recall of biological content. The flow map, science interest questionnaire and the cognitive operations (based on content analysis of student's narrative) were used to analyze data from each respondent. This is a case study using individual subjects and interview techniques. The findings of this study are: (1) Based on flow map data higher academic ability students have more networking of ideas than low ability students. (2) A large percentage of 9th grade low ability students intend to pursue science/applied science course work after leaving school but they lack well organized ways of representing science knowledge in memory. (3) Content analysis of the narratives shows that students with more complex ideational networks use higher order cognitive thought processes compared to those with less networking of ideas. If students are to make a successful transition from low academic performance to high academic performance it seems that more emphasis should be placed on

  12. Build a Catastrophe: Using Digital World and Policy Models to Engage Political Science Students with Climate Change

    Horodyskyj, L.; Lennon, T.; Mead, C.; Anbar, A. D.

    2017-12-01

    Climate change is a problem that involves science, economics, and politics. Particularly in the United States, political resistance to addressing climate change has been exacerbated by a concerted misinformation campaign against the basic science, a negative response to how the proposed solutions to climate change intersect with values. Scientists often propose more climate science education as a solution to the problem, but preliminary studies indicate that more science education does not necessarily reduce polarization on the topic (Kahan et al. 2012). Is there a way that we can better engage non-science students in topics related to climate change that improve their comprehension of the problem and its implications, overcoming polarization? In an existing political science course, "Do You Want to Build a Nation?", we are testing a new digital world-building model based on resource development and consequent environmental and societal impacts. Students spend half the class building their nations based on their assigned ideology (i.e., socialist, absolute monarchy, libertarian) and the second half of the class negotiating with other nations to resolve global issues while remaining true to their ideologies. The course instructor, co-author Lennon, and ASU's Center for Education Through eXploration have collaborated to design a digital world model based on resources linked to an adaptive decision-making environment that translates student policies into modifications to the digital world. The model tracks students' exploration and justification of their nation's policy choices. In the Fall 2017 offering of the course, we will investigate how this digital world model and scenarios built around it affect student learning outcomes. Specifically, we anticipate improved understanding of the policy trade-offs related to energy development, better understanding of the ways that different ideologies approach solutions to climate change, and that both will result in more
