  2. Tertiary ?18O record and glacio-eustatic sea-level fluctuations

    NASA Astrophysics Data System (ADS)

    Matthews, R. K.; Poore, R. Z.

    1980-10-01

    Previous interpretation of the Tertiary ?18O record of plaiiktic and benthic foraminifers has emphasized comparison to the modern ocean, assumed an ice-free world prior to middle Miocene time, and thereby calculated surprisingly cool temperatures for the tropical sea surface. We propose an alternative interpretation, which compares Tertiary data to average late Pleistocene, assumes constant tropical sea-surface temperature, and thereby estimates global ice volume. This approach suggests that Earth has had a significant ice budget (and therefore glacio-eustatic sea-level fluctuations) at least since Eocene and perhaps even throughout much of Cretaceous time.

    We performed customer satisfaction surveys for physicians and nurses regarding clinical laboratory services, and for outpatients who used phlebotomy services at a tertiary care unit level to evaluate our clinical laboratory and phlebotomy services. Thus, we wish to share our experiences with the customer satisfaction survey for clinical laboratory and phlebotomy services. Board members of our laboratory designed a study procedure and study population, and developed two types of questionnaire. A satisfaction survey for clinical laboratory services was conducted with 370 physicians and 125 nurses by using an online or paper questionnaire. The satisfaction survey for phlebotomy services was performed with 347 outpatients who received phlebotomy services by using computer-aided interviews. Mean satisfaction scores of physicians and nurses was 58.1, while outpatients' satisfaction score was 70.5. We identified several dissatisfactions with our clinical laboratory and phlebotomy services. First, physicians and nurses were most dissatisfied with the specimen collection and delivery process. Second, physicians and nurses were dissatisfied with phlebotomy services. Third, molecular genetic and cytogenetic tests were found more expensive than other tests. This study is significant in that it describes the first reference survey that offers a survey procedure and questionnaire to assess customer satisfaction with clinical laboratory and phlebotomy services at a tertiary care unit level.

    2015-01-01

    Background: Leprosy has been officially eliminated from India since December, 2005; still, there are districts and blocks reporting high prevalence indicating ongoing transmission. The present study aimed at determining the current clinical profile of leprosy from a tertiary level hospital in Delhi. Materials and Methods: A retrospective, record-based study was carried out on patients diagnosed and registered in the leprosy clinic of a tertiary level teaching hospital in East district of Delhi (April 2007 to March 2012). Data regarding demographic details, clinical features, treatment started and complications was analyzed. Results: A total of 849 patients were registered over a 5-year period, with M: F ratio of 2.3:1. 9.3% were children (ā‰¤14 years). 54.3% patients were immigrants from adjoining states. Multibacillary leprosy was the most common clinical type (86.9%). Borderline tuberculoid leprosy was the most frequent morphologic type, seen in 56.3% followed by borderline-borderline (1.5%), borderline lepromatous (24.9%), lepromatous leprosy (8.1%), pure neuritic (8.1%), histoid and indeterminate leprosy (0.5% each). 37.4% patients presented in reaction (Type I in 30.4% cases and Type II in 7% cases). WHO grade II deformities were diagnosed in 37.9% with claw hand being the most common paralytic deformity (23.3% cases). Conclusion: Our study offers insight into the current status of the disease in an area of otherwise low prevalence. It is seen that despite statistical elimination, multibacillary disease, leprosy reactions and deformities are commonly seen as presenting manifestations, in contrast to national projected trends. Delhi's unique demography with a high degree of migrant workers, presenting to our center (near border location) could be a possible contributing factor towards these aberrations. It highlights the need for continuation of targeted leprosy control activities and active case detection. PMID:25657398

  13. Dinoflagellate and calcareous nannofossil response to sea-level change in Cretaceous-Tertiary boundary sections

    1992-02-01

    Stratigraphic sections in south-central Alabama were studied to test palynological evidence of sea-level change across the Cretaceous-Tertiary boundary. New evidence from both calcareous nannofossils and dinoflagellate cysts places the regional disconformity in Alabama (Type 1 sequence boundary) virtually at the K-T boundary. This suggests that sea-level fall may have contributed to mass-extinction event. Dinoflagellate diversity varies between systems tract components of coastal onlap. This parameter is useful for interpreting sea-level change in this part of the section, because dinoflagellates did not participate in the mass extinction. The iridium spikes in the roadcut near Braggs are of earliest Danian age and correlate in relative magnitude with the lower values reported from directly above the K-T boundary in the Gubbio stratotype section. Iridium was concentrated in marine flooding surfaces in episodes of higher productivity of algal organic matter at the time when the iridium-enriched ocean encroached on the shelf during the first Cenozoic episode of sea-level rise.

    Study Design Prospective, cross-sectional, observational study. Purpose Spine traumata are devastating injuries, which may result in serious disabilities and dire consequences. The current study involves a detailed analysis and description of patients, who were operated at a tertiary care, urban level 1 Spine Centre in India. Overview of Literature Various studies in literature have discussed the epidemiology and patterns of these injuries in trauma patients. However, literature describing the demographic profile and distribution of these traumata in the Indian population is scarce. Methods The current study was conducted as a prospective trial involving patients, who were treated at our Spine Centre in India between July 2009 to December 2012. We studied 92 patients with thoraco-lumbar spine fracture, who were operated with short or long segment posterior stabilization. Epidemiological details, pre- and post-hospitalisation care received and other injury pattern factors were studied. Results Fall from height (46 patients, 50%) was the most common mechanism observed in the patients. Sixty-three percent injuries belonged to AO type A fractures, while 16.2% and 19.4% of the patients had suffered from AO types B and C injuries, respectively. Conclusions We identified interesting epidemiological data and prevailing inadequacies in Emergency Spine care management in the study patients. These observations could facilitate implementation of the changes required to improve current standards of patient care. PMID:26097649

  2. Population and Colony-Level Determinants of Tertiary Sex Ratio in the Declining Barn Swallow

    Saino, Nicola; Romano, Maria; Rubolini, Diego; Caprioli, Manuela; Ambrosini, Roberto; Boncoraglio, Giuseppe; Canova, Luca

    2013-01-01

    Sex ratio of adults (tertiary sex ratio, TSR) is a major feature of animal populations with consequences for their behaviour, genetic structure and viability. Spatial and temporal variation in TSR occurs within species but the mechanisms behind it are poorly understood. In this long-term study of a declining population of a socially monogamous, colonial, migratory bird, the barn swallow (Hirundo rustica), we first analyzed population-level variation in TSR (?=?proportion of males) of yearlings at sexual maturation in relation to ecological conditions as gauged by annual survival rate of adults. TSR was male-biased both among yearlings and older individuals, but male bias of yearlings was more pronounced after years with larger decline in adult survival. Thus, male offspring were less susceptible to the adverse ecological conditions that cause increased mortality. Dispersal and settling site decisions can have major consequences on fitness via the effects of local TSR on mating and sperm competition. Breeding barn swallows are highly philopatric while natal dispersal is high and, together with mortality, is the main determinant of colony TSR. We thus also investigated the mechanisms of breeding colony choice by yearlings and found that TSR of new-settlers in a given colony and year was negatively predicted by TSR of returning, early arriving older individuals in that year, but not by overall TSR at the colony in the previous year. This suggests that in our male-biased population new-settler males respond to local TSR upon arrival to choose the sites with larger breeding opportunities. Hence, variation in ecological conditions as reflected by adult survival can shift the TSR of individuals recruiting into a local population, with potentially various demographic consequences. However, breeding site choice based on TSR tends to homogenize TSR at a population level likely by facilitating settling of dispersing males in colonies with less male-biased TSR. PMID:23418577

  3. Costs of vaginal delivery and Caesarean section at a tertiary level public hospital in Islamabad, Pakistan

    PubMed Central

    2010-01-01

    Background Public hospitals in developing countries, rather than the preventive and primary healthcare sectors, are the major consumers of healthcare resources. Imbalances in rational, equitable and efficient allocation of scarce resources lie in the scarcity of research & information on economic aspects of health care. The objective of this study was to determine the average cost of a spontaneous vaginal delivery and Caesarean section in a tertiary level government hospital in Islamabad, Pakistan and to estimate the out of pocket expenditures to households using these services. Methods This hospital based cost accounting cross sectional study determines the average cost of vaginal delivery and Caesarean section from two perspectives, the patient's and the hospital. From the patient's perspective direct and indirect expenditures of 133 post-partum mothers (65 delivered by Caesarean section & 68 by spontaneous vaginal delivery) admitted in the maternity general ward were determined. From the hospital perspective the step down methodology was adopted, capital and recurrent costs were determined from inputs and cost centers. Results The average cost for a spontaneous vaginal delivery from the hospital's side was 40 US$ (2688 rupees) and from the patient's perspective was 79 US$ (5278 rupees). The average cost for a Caesarean section from the hospital side was 162 US$ (10868 rupees) and 204 US$ (13678 rupees) from the patient's side. Average monthly household income was 141 Ā± 87 US$ for spontaneous vaginal delivery and 168 Ā± 97 US$ for Caesarean section. Three fourth (74%) of households had a monthly income of less than 149 US$ (10000 rupees). Conclusion The apparently "free" maternity care at government hospitals involves substantial hidden and unpredicted costs. The anticipated fear of these unpredicted costs may be major factor for many poor households to seek cheaper alternate maternity healthcare. PMID:20085662

  11. A study of understanding: Alchemy, abstraction, and circulating reference in tertiary science education

    NASA Astrophysics Data System (ADS)

    Merritt, Brett W.

    Understanding is widely touted to be of paramount importance for education. This is especially true in science education research and development where understanding is heralded as one of the cornerstones of reform. Teachers are expected to teach for understanding and students are expected to learn with understanding. This dissertation is an empirical study of the concept of understanding. After analyzing various constructions of understanding in current U.S. education literature, I suggest that understanding is defined by five distinct features---they are knowledge (or knowledge base), coherence, transfer, extrapolation, and cognition--- and that these features are heavily informed and shaped by the psychological sciences. This relationship is neither good nor bad, I argue, but it means that teaching for and learning with understanding are not heavily informed and shaped by, for example, the natural sciences. Drawing from historical, philosophical, and anthropological perspectives of science, but especially from the work of Bruno Latour, I enact a radical revision(ing) of psychological notions such as "abstraction" and "transfer." The two main purposes of this re-visioning are (1) to draw critical attention to particular characteristics of a cognitive learning theory that emphasizes abstract concepts, and (2) to align many of the principles and tools used in science education more closely with those used in empirical scientific research. Finally, by bringing some examples of teaching and learning from an undergraduate biology classroom into conversation with both psychological and empirical practices and perspectives, I suggest that problematizing the current construction of understanding creates much needed room in mainstream science education for more empirical forms of learning and styles of teaching. A shift to such forms and styles, I conclude, should prove to be more inclusive and less constraining for both students and teachers.

  2. Antibiotic Prescribing Pattern in a Tertiary Level Neonatal Intensive Care Unit

    PubMed Central

    Pandit, Vijaya; Suryawanshi, Pradeep; Panditrao, Aditi

    2015-01-01

    Introduction Neonatal sepsis is a major cause of morbidity and mortality worldwide especially in developing countries, which justifies early diagnosis and prompt treatment with antibiotics. Antibiotics are the most frequently used medicines in Neonatal Intensive care units. Data regarding rational antibiotic use in neonates is very limited. Hence, it is essential that the antibiotic prescribing patterns be evaluated periodically for its rational use. Therefore, the present study been carried out to identify the prescribing patterns of antibiotics in neonatal intensive care unit of a tertiary care hospital, Western Maharashtra, India. Materials and Methods A prospective observational study was carried out for 6 months between April to September 2014. The data regarding patient demographics and antibiotic use was collected daily in a structured proforma. Collected data was subjected to statistical analysis. Results Out of total 528 neonates with male preponderance (62%), 370 received antibiotics. Mean gestational age and birth weight were 35±3.2 weeks and 2±0.7 kg respectively. Mean length of hospital stay was 14.26±15.36 days (range 1 to 136 days). A total of 1123 antibiotics were prescribed to 370 neonates. The majority of neonates (55.9%) received between 1-2 antibiotics, 37.3% had 3 to 5 antibiotics prescribed, while 6.7% neonates were prescribed more than 5 antibiotics. Number of antibiotics used had statistically significant inverse relationship with gestational age. Among antibiotics; Amikacin, Cefotaxime and Levofloxacin were the drugs most often prescribed. Amikacin and Cefotaxime were given more to term infants whereas other antibiotics like Levofloxacin, Pipercillin- tazobactam and Meropenem were prescribed more to preterm and outborn neonates. Conclusion The use of a high number of antibiotics is a common practice. Although the indications for use of most antibiotics could be justified, the increased frequency of anbiotics use in some neonates was of concern. Guidelines for the use of antibiotics in neonates are required and larger studies are needed on this issue. PMID:26672773

    2015-01-01

    Current legislation transferred public tertiary hospitals in Bolivia from the Municipalities to the Regional Level. However, the Regional Governments are experiencing technical and financial constraints to reform infrastructure, modernize equipment and introduce reforms to allow better governance, management and sustainability of these hospitals. This articles summarizes the recent experience of the Government of Santa Cruz de la Sierra in Bolivia where five tertiary hospitals and blood bank (most of them in precarious working conditions) has been transferred in 2012 from the Municipal Government of Santa Cruz (the capital) to the Regional Government of Santa Cruz. To face the challenges, the Regional Government of Santa Cruz implement several improvements, such as contract new clinical and administrative personal, increases hospital budgetary autonomy, outsource hospitals' auxiliary services, take measures to eliminate waiting lists and make several new investments to modernize and equip the hospitals. The World Bank was contracted to evaluated the future financial sustainability of these investments and to advice the Government to propose changes to increase the hospitals' management performance. The article describes the remaining challenges in these hospitals and the proposals from the World Bank Study. In the area of quality of care, the main challenge is to improve client satisfaction and continuous outcomes monitoring and evaluation according quality standards. In the area of financing, the challenge is how to assure the sustainability of these hospitals with the current level of health financing and the insufficient financial transfers from the National Government. In the area of Governance, reforms to streamline and simplify internal processes need to be introduced in order to establish mechanisms to increase transparency and accountability, allowing the hospital to have a good administration and adequate participation of the main actors in the guidance of the institution.

  4. System-level musings about system-level science (Invited)

    NASA Astrophysics Data System (ADS)

    Liu, W.

    2009-12-01

    In teleology, a system has a purpose. In physics, a system has a tendency. For example, a mechanical system has a tendency to lower its potential energy. A thermodynamic system has a tendency to increase its entropy. Therefore, if geospace is seen as a system, what is its tendency? Surprisingly or not, there is no simple answer to this question. Or, to flip the statement, the answer is complex, or complexity. We can understand generally why complexity arises, as the geospace boundary is open to influences from the solar wind and Earth’s atmosphere and components of the system couple to each other in a myriad of ways to make the systemic behavior highly nonlinear. But this still begs the question: What is the system-level approach to geospace science? A reductionist view might assert that as our understanding of a component or subsystem progresses to a certain point, we can couple some together to understand the system on a higher level. However, in practice, a subsystem can almost never been observed in isolation with others. Even if such is possible, there is no guarantee that the subsystem behavior will not change when coupled to others. Hence, there is no guarantee that a subsystem, such as the ring current, has an innate and intrinsic behavior like a hydrogen atom. An absolutist conclusion from this logic can be sobering, as one would have to trace a flash of aurora to the nucleosynthesis in the solar core. The practical answer, however, is more promising; it is a mix of the common sense we call reductionism and awareness that, especially when strongly coupled, subsystems can experience behavioral changes, breakdowns, and catastrophes. If the stock answer to the systemic tendency of geospace is complexity, the objective of the system-level approach to geospace science is to define, measure, and understand this complexity. I will use the example of magnetotail dynamics to illuminate some key points in this talk.

    2015-01-01

    Background Poisoning is becoming a real health care burden for developing countries like India. An improved knowledge of the patterns of poisonings, as well as the clinical course and outcomes of these cases can help to formulate better preventive and management strategies. Aim To study the demographic and clinical profiles of patients admitted to the ICU with acute poisoning and to study the factors that predict their mortality. Materials and Methods Retrospective two years (September 1, 2010 to August 31, 2012) study of all consecutive patients admitted to the Intensive Care Unit (ICU) with acute poisoning at a tertiary care hospital in Northern India. Results Out of the 67 patients admitted to the ICU during the study period, the majority were young (median age 29 years) males (69%) who had consumed poison intentionally. Pesticides were the most commonly employed poison, notably organophosphorus compounds (22 patients, 32.8%) and aluminium phosphide (14 patients, 20.9%). While the overall mortality from all poisonings was low (18%), aluminium phosphide was highly toxic, with a mortality rate of 35%. The factors at ICU admission that were found to be associated with a significant risk of death were, high APACHE II and SOFA scores (p =0.0001 and p=0.006, respectively), as well as the need for mechanical ventilation and drugs for vasoactive support (p=0.012 and p= 0.0001, respectively). Conclusion Use of pesticides for intentional poisoning continues to be rampant in Northern India, with many patients presenting in a critical condition to tertiary level hospitals. Pesticide regulations laws, educational awareness, counseling and poison information centers will help to curtail this public health problem. PMID:26557594

    2015-01-01

    Background: There is insufficient information on causes of unsafe care at facility levels in India. This study was conducted to understand the challenges in government hospitals in ensuring patient safety and to propose solutions to improve patient care. Materials and Methods: Desk review, in-depth interviews, and focused group discussions were conducted between January and March 2014. Healthcare providers and nodal persons for patient safety in Gynecology and Obstetrics Departments of government health facilities from Delhi state of India were included. Data were analyzed using qualitative research methods and presented adopting the ā€œhealth system approach.ā€ Results: The patient safety was a major concern among healthcare providers. The key challenges identified were scarcity of resources, overcrowding at health facilities, poor communications, patient handovers, delay in referrals, and the limited continuity of care. Systematic attention on the training of care providers involved in service delivery, prescription audits, peer reviews, facility level capacity building plan, additional financial resources, leadership by institutional heads and policy makers were suggested as possible solutions. Conclusions: There is increasing awareness and understanding about challenges in patient safety. The available local information could be used for selection, designing, and implementation of measures to improve patient safety at facility levels. A systematic and sustained approach with attention on all functions of health systems could be beneficial. Patient safety could be used as an entry point to improve the quality of health care services in India. PMID:26985411

    This article presents findings of a study which assessed the nutritional knowledge levels of nursing students as nurses are in a better position to serve as nutrition educators and counselors by engaging their clients in discussions that would increase their knowledge about disease prevention and management through nutrition. This was a descriptive cross-sectional study, where a selfadministered questionnaire was completed by 166 undergraduate consenting third (3rd) and final (4th) year nursing students in a public university in Ghana who answered 20 multiple choice general nutrition questions. An average score of 8.95 Ā± 2.01 corresponding to 44.8%, below average, was obtained by the respondents. It was determined that the nutrition knowledge of 3.6%, 62.7% and 33.7% of the study participants was good, adequate and inadequate respectively. It was found that the differences with respect to the nutrition knowledge levels between the age groups, gender, work experience and educational background of respondents were not statistically significant at p < 0.05. The findings of this study support other reports that nurses need more training in nutrition and therefore have important implications for professionals planning curricula for nursing education at the undergraduate level in the university.

    2014-01-01

    Aims: To assess the level and factors of motivation amongst permanent government employees working in a tertiary health care institution. Material and Methods: A sample of 200 health personnel (50 in each category) i.e. doctors, nurses, technician, and support staff were contacted through face to face interview. Motivation was measured as the degree to which an individual possessed various identified motivation domains like Drive, Control, Challenge, Relationship and Rewards. Each domain was represented by 4 dimensions- accordingly a closed-ended statement represented each of these dimensions and responses were assessed on a Likert based scale. Data management was done using SPSS, ver. 19. Results: The average age for different health personnel were: Doctors 48.68 (±8.53), nurses 40.72 (±7.76), technician 38.4 (±10.65) and support staff 43.24 (±9.52) years. The average year of work experience was: Doctor 19.09 (±9.77), nurses 17.2 (±8.420), technician 14.84 (±10.45), support staff 18.24 (±10.28). A comparison of overall motivation index (mean score) revealed that nurse had highest level (3.47), followed by support staff (3.46), doctor (3.45) and technician (3.43). Based on their individual mean scores, the healthcare providers were categorised into three different levels of motivation and it was found that majority of the health personnel i.e.70% of support staff, 62% nurse, 56% doctor and technician, had high to very high level of motivation index. The mean scores for all the five factors as well as their respective ranks were also found out and it was deduced that “relationship” assumed first rank for doctors (mean score: 3.71) and technician (mean score: 3.75), whereas “control” assumed greatest significance for nurses (mean score, 3.62) and support staff (mean scores, 3.61). Based upon the mean scores, “reward” assumed third rank among all the four categories. Kruskal-Wallis test was applied to test if the different categories of health personnel varied with respect to five factors of motivation and it was found that their orientation towards the various motivational components differed significantly only with respect to Drive (P < 0.01). Conclusion: There is scope for enhancing staff motivation. PMID:25364148

  1. Characteristics of obstetrical inpatients referred to a consultation-liaison psychiatry service in a tertiary-level university hospital.

    Sloan, Eileen P; Kirsh, Sharon

    2008-12-01

    A review of psychiatric consult notes of 96 obstetric inpatients referred to a Consultation-Liaison (C-L) psychiatry service in a tertiary-level university general hospital was carried out in order to compare the characteristics of such a service in a North American setting with similar services in other parts of the world. Data extracted from consult notes included: reason for referral, current diagnosis (DSM-IV-R), psychiatric history, obstetrical history, recommended treatment approaches, current psychotropic medications, current gestational age or number of days postpartum, patient age, and partnership status. In addition, obstetrical referrals were calculated as a percentage of hospital-wide referrals to C-L psychiatry. The most prominent findings include: (1) a high C-L psychiatry referral rate from obstetrics as a percentage of total C-L referrals within the study hospital; (2) past psychiatric history alone as a prevalent reason for referral; (3) adverse reproductive event (past and/or current) as a common reason for referral. These findings differ markedly in certain ways from comparable studies and may reflect both the hospital's large high-risk pregnancy service that represents an at-risk group for mental health issues, and the focus on educational collaboration with obstetrical staff regarding risk factors for, and consequences of, perinatal mental illness. Inpatient perinatal C-L psychiatric services require creative approaches to the accurate identification and treatment of women at risk for antenatal and postpartum mental illness due to psychiatric history and/or reproductive crises.

  3. The elementary level science methods course: Breeding ground of an apprehension toward science? a case study

    NASA Astrophysics Data System (ADS)

    Duschl, Richard A.

    Ethnographic research methodologies were used to examine the training of elementary education majors in science in an attempt to gain insight on whether or not their training in science contributes to the apprehension elementary teachers have toward science. The field study consisted of 14 weeks of weekly observations in the elementary education majors science methods class. Interviews with the students and the instructors as well as survey instruments to assess students' preparation in science were used. Two different approaches to the study of science, one content oriented, the other process oriented, may contribute to the students' confusion, insecurity, and avoidance of science. The students' perception that science is learning content, an objective of introductory level science courses, and the science methods class's objectives of teaching science as a process sets up an antagonistic dilemma between the two. Such antagonistic dilemma may be manifest in the lack of instructional time accorded to science by elementary educators. The type of science experiences an individual encounters influences their perceptions. To offset student perceptions developed in science courses which stress principally content, the students need science experiences which truly represent science as inquiry. New strategies for the training of elementary education majors in science need to be examined.

    2014-05-01

    This audit was performed in the obstetrics and gynaecology department of a tertiary referral hospital, to investigate the use and results of TORCH screening. St Michael's Hospital delivers approximately 6,000 women from South Bristol a year and receives tertiary referrals from the South West of England and South Wales. It was found that 739 patients over a 6-year period from April 2006 to January 2012 underwent testing. The majority's indication (21%) was polyhydramnios. Three patients had evidence of primary CMV infection in pregnancy on serology, two for fetal indications (polyhydramnios and echogenic bowel) and one following a miscarriage. There were no confirmed cases of gestational toxoplasma or rubella. Routine testing for toxoplasma and rubella infection as part of the TORCH screening in cases of fetal or obstetric abnormality should thus be discontinued in our population. PMID:24476395

    Singh, Mamta K.

    Although the educational evaluation process is useful and valuable and is supported by the Higher Education Act, a strong research base for program evaluation of college entry-level science courses is still lacking. Studies in science disciplines such as, biology, chemistry, and physics have addressed various affective and demographic factors and their relationships to student achievement. However, the literature contains little information that specifically addresses student biology content knowledge skills (basics and higher order thinking skills) and identifies factors that affect students' success in entry-level college science courses. These gate-keeping courses require detailed evaluation if the goal of an institution is to increase students' performance and success in these courses. These factors are, in fact, a stepping stone for increasing the number of graduates in Science, Technology, Engineering, and Mathematics (STEM) majors. The present study measured students' biology content knowledge and investigated students' performance and success in college biology, chemistry, and physics entry-level courses. Seven variables---gender, ethnicity, high school Grade Point Average (GPA), high school science, college major, school financial aid support, and work hours were used as independent variables and course final performance as a dichotomous dependent variable. The sample comprised voluntary student participants in entry-level science courses. The study attempted to explore eight research questions. Content knowledge assessments, demographic information analysis, multiple regression analysis, and binary logistic regression analysis were used to address research questions. The results suggested that high school GPA was a consistently good predictor of students' performance and success in entry-level science courses. Additionally, high school chemistry was a significant predictor variable for student success in entry-level biology and chemistry courses. Similarly, students' performance and success in entry-level physics courses were influenced by high school physics. Finally, the study developed student success equation with high school GAP and high school chemistry as good predictors of students' success in entry-level science courses.

  15. Tertiary Hyperparathyroidism

    PubMed Central

    Davies, D. R.; Dent, C. E.; Watson, Lyal

    1968-01-01

    In our first 200 cases of primary hyperparathyroidism confirmed by operation 12 were also shown to have a long history either of a malabsorption syndrome or of chronic renal-glomerular failure. We consider that they first went through a phase of secondary hyperparathyroidism, during which one or more of the glands became autonomous adenamata. This then produced the biochemical changes of “primary” hyperparathyroidism, necessitating excision of the adenoma. This condition is best described as “tertiary” hyperparathyroidism. The transition from secondary to tertiary hyperparathyroidism occurred in four of the 12 patients while under our observation. We think the same process can be traced retrospectively in the other eight cases. The concept of tertiary hyperparathyroidism may help to explain the high incidence of other diseases in association with primary hyperparathyroidism. The behaviour of the parathyroid glands provides a valuable model for the investigation of tumour formation in man. All states occurred in our patients with primary hyperparathyroidism, from normal through hyperplasia to adenoma formation and finally to parathyroid carcinoma. PMID:5691200

    Weiland, Sunny Minelli

    This study implemented a qualitative approach to examine the phenomenon of "inquiry-based science pedagogy or inquiry instruction" as it has been experienced by individuals. Data was collected through online open-ended surveys, focus groups, and teacher reported self-reflections to answer the research questions: 1) How do middle level science teachers conceptualize "inquiry-based instruction?" 2) What are preferred instructional strategies for implementation in middle level science classrooms? And 3) How do middle level science teachers perceive the connection between science instruction and student learning? The participants within this research study represent 33 percent of teachers in grades 5 through 9 within six school districts in northeastern Pennsylvania. Of the 12 consent forms originally obtained, 10 teachers completed all three phases of the data collection, including the online survey, participation in focus groups, and teacher self-reflection. 60 percent of the participants taught only science, and 40 percent taught all content areas. Of the ten participants, 50 percent were certified teachers of science and 50 percent were certified as teachers of elementary education. 70 percent of the research participants reflected having obtained a master's, with 60 percent of these degrees being received in areas of education, and 10 percent in the area of science. The research participants have a total of 85 collective years of experience as professional educators, with the average years of experience being 8.5 years. Analysis of data revealed three themes related to research question #1) How do middle-level science teachers conceptualize inquiry-based instruction? and sub-question #1) How do middle-level science teachers characterize effective instruction? The themes that capture the essence of teachers' formulation of inquiry-based instruction that emerged in this study were student centered, problem solving, and hands-on . Analysis of data revealed one theme related to research question #2) What are preferred instructional strategies for implementation in middle level science classrooms? and topical sub-question #2) How do middle level science teachers structure instruction. The theme that emerged was needs of students. Analysis of the data revealed one theme related to research question #3) How do middle level science teachers perceive the relationship between science instruction and student learning? and topical sub-question #3) How do middle level science teachers view their role in relation to student learning? This theme is meaning making. Analysis of the data related to meaning making revealed two sub-themes of application and relationships. It is clear that middle level science teachers have a vision for inquiry-based science instruction, but implementation is inhibited by a variety of factors including curricular programming that is very broad and lacks depth, the scheduling of time and resources for science, and the absence of a clear model of inquiry-based instruction. In addition, only one participant referenced students investigating their own authentic questions and no participants reflected on the importance of students using evidence in their explanations of scientific phenomenon. Additionally, participants continually reflected on the needs of their students informing instructional practices, and it is wondered if there is a clear understanding among middle level teachers of how students learn science. Real world applications were recognized as important within science learning and the researcher questions whether teachers of science have adequate opportunities to explore real world application of science concepts throughout their careers in order to foster connections within the classroom. These findings support the need for strong, job-embedded professional development, the cultivation of learning communities dedicated to the investigation and implementation of inquiry-based science, the focusing of curricular programming to allow for in depth investigation of scientific concepts, and the commitment of time and resources to support effective science instruction. In addition, it is recommended that additional support be provided to teachers of science to engage in job shadowing, field experiences and internships to allow for the uncovering of applications of science beyond the classroom. Throughout the United States, there continues to be a clear call for reform in the area of science education. These research findings must inform the work of the educational reformers, professional developers, teacher preparation programmers, and researchers as they aspire to improve the quality of student learning and science instruction. In addition, this research supports the need for ongoing reform efforts to science curriculum, instruction and assessment and the need for more effective teacher preparation programs and professional development programs for teachers of science.

    Community interventions are complex social processes that need to move beyond single interventions and outcomes at individual levels of short-term change. A scientific paradigm is emerging that supports collaborative, multilevel, culturally situated community interventions aimed at creating sustainable community-level impact. This paradigm is rooted in a deep history of ecological and collaborative thinking across public health, psychology, anthropology, and other fields of social science. The new paradigm makes a number of primary assertions that affect conceptualization of health issues, intervention design, and intervention evaluation. To elaborate the paradigm and advance the science of community intervention, we offer suggestions for promoting a scientific agenda, developing collaborations among professionals and communities, and examining the culture of science.

    This study describes the epidemiology of unintentional adult burn injury admissions in a tertiary hospital in Nepal, from 2002 to 2013, focusing on gender-specific patterns. Chi-square tests and Wilcoxon Rank Sum tests were performed. There were 819 unintentional burn admissions: 52% were male and 58% younger than 35 years. The median percentage total body surface area burned (interquartile range) was greater in females than in males (P < .001): 28% (17-40) versus 20% (12-35), and female mortality was higher (32% vs 11%). A higher proportion females were illiterate than males (48% vs 17%). Burns occurred at home (67%), work (28%), and public places (5%); gender-specific patterns were observed. Flame burns accounted for 77%, electricity 13%, and scalds 8%. Kerosene (31%) and biomass (27%) were the major fuels. Cooking, heating, and lighting were the main activities associated with burn injury. Results support interventions to reduce the use of open fires and kerosene and to promote electrical safety.

    Aim: To correlate the level of anxiety with nonadherence to antiretroviral medication. Materials and Methods: This observational, cross-sectional, hospital-based study was conducted in 78 patients attending antiretroviral therapy (ART) center of a tertiary care hospital of Odisha. The study duration was 6 months. Patients were designated as nonadherent by referring to the white card. Utilization of ART drugs and adverse drug reactions were included in a predesigned format. The anxiety level of all included patients was scored as per Hamilton Anxiety Rating Scale. Mean anxiety score of the adherent group was compared with that of the nonadherent group. Possible causes of nonadherence leading to high anxiety level were evaluated. Results: 46% of patients in the nonadherent group had very severe, 17% had moderate to severe, 28% had mild to moderate and 9% had a mild level of anxiety. In the adherent group, however, mild to moderate level of anxiety was observed only in 10% patients. Conclusions: Anxiety is associated with sub-optimal medication adherence in HIV infected patients.

    Background Stroke is a heterogeneous disease with several risk factors. High sensitivity C-reactive protein (hsCRP) is a marker for cardiovascular and cerebrovascular diseases. Recent studies have shown that high hsCRP level is a risk factor for ischemic stroke. The objective of our study was to investigate the association of high hsCRP (> 3 mg/L) levels with ischemic stroke and its subtypes in Indian patients. Methods We recruited 210 consecutive acute stroke patients and 150 age and sex matched controls. Stroke patients were admitted within 72 hours of onset, at Yashoda Hospital, Hyderabad, India. The study period was from January 2011 to December 2012. All patients underwent tests as per standard protocol for stroke workup. Serum hsCRP level was assessed in all stroke patients and controls on the day of admission. Results The mean hsCRP was significantly higher in stroke patients (3.8 ± 2.5) than controls (1.8 ± 1.5) (P < 0.001). High hsCRP had higher frequency in stroke patients 130 (61.9%) compared to controls 10 (6.6%), P < 0.001. High hsCRP level was more prevalent in the stroke subtypes of cardioembolic stroke (83.3%) and large artery atherosclerosis (72%). High hsCRP level was significantly associated with hypercholesterolemia (P = 0.001), age (P = 0.01), and mortality (0.04). After adjustment of regression analysis it was observed that high level hsCRP is independently associated with acute ischemic stroke (Odds 4.5; 95% CI: 2.5-12.2); especially the stroke subtypes of cardioembolic stroke, (odds ratio 3.4, 95% CI: 1.9-10.5) and large artery atherosclerosis (odds ratio 2.1, 95% CI: 1.5-3.8). Conclusion High hsCRP level is strongly associated with and an independent predictor of acute ischemic stroke. The association was found in all ischemic stroke subtypes. PMID:24250912

    2005-12-01

    The Semantic Web for Earth and Environmental Terminology (SWEET) provides a set of upper-level ontologies constituting a concept space of Earth system science. These ontologies can be used, mapped, or extended by developers of specialized domain ontologies. SWEET components are being adopted within a diverse range of applications, including: the Geosciences Network (GEON), the Marine Metadata Initiative (MMI), the Virtual Solar Terrestrial Observatory (VSTO), and the Earth Science Markup Language (ESML). SWEET includes 12 ontologies, decomposed into component parts that can be reassembled to meet the needs of user communities. For example, the Property ontology terms (e.g., temperature, pressure) can be associated with measurable (observable) quantities of a dataset. The Substance ontology provides representations of the substance in which a property is being measured (e.g., air, water, rock). The Earth Realm ontology provides representations for the environmental regions of the Earth (e.g., atmospheric boundary layer, ocean mixed layer). The Data and Service ontology enables representations of how data are captured, stored, and accessed. The Numerics ontology entries represent 2-D and 3-D objects or spatial/temporal entities and relations. The Human Activities ontology captures the human side or applications of Earth science. The Phenomena ontology describes major geophysical or geophysical-related events. All of the ontologies are written in the OWL-DL language to give domain specialists a starting vocabulary, over which layers, synonyms, or extensions can be applied.

    Introduction: Intracranial suppurations (ICS) of bacterial origin are associated with significant mortality and morbidity. This study aimed to review demography, etiology, level of consciousness, and outcome of surgical ICS in a tropical tertiary hospital. Materials and Methods: All patients admitted to the neurosurgical unit within the study period of 7 years that had a surgical intervention for their ICS were prospectively included in the study. In accordance with the unit protocol, all patients in whom there was clinical suspicion of ICS had a preoperative computed tomography scan and/or magnetic resonance imaging done. The following data among others were documented and recorded electronically: demography, clinical and radiological diagnosis, etiology of ICS, admission Glasgow Coma Scale (GCS) score, type of neurosurgical intervention, mode of anesthesia, and outcome. Results: Forty-nine patients were included in the study. There were 33 males with a male-to-female ratio of 2.1:1. All patients presented at least a week after the use of antibiotics. The most common type of ICS was cerebral abscess (33 patients, 67.3%). There was no statistical significant association between outcome and age group (P = 0.630), gender (P = 0.999), diagnosis (P = 0.464), etiology of ICS (P = 0.169), solitary or multiplicity of ICS (P = 0.485), or type of offending organism (P = 0.278). Conclusions: ICS usually follows otorhinological infections in our center. The surgical outcome is dependent on the admission GCS score. PMID:26889278

    Science education must be a priority for citizens to function and be productive in a global, technological society. African Americans receive fewer science degrees in proportion to the Caucasian population. The primary purposes of this study were to determine the difference between the pretest and posttest science self-efficacy scores of African-American nonscience majors, the difference between the pretest and posttest science self-efficacy scores of African-American science majors, the relationship between science self-efficacy and course grade, the relationship between gender and science self-efficacy score, and the relationship between science self-efficacy score and course withdrawal. This study utilized a Likert survey instrument. All participants were enrolled in freshman level courses in the physical sciences at a historically black institution: a college or university. Participants completed the pretest survey within two weeks after the 12th class day of the semester. Initially, 458 participants completed the pretest survey. The posttest was administered within two weeks before the final exam. Only 245 participants completed the posttest survey. Results indicate that there is a difference in science self-efficacy of science majors and nonscience majors. There was no significant difference between the pretest and posttest science self-efficacy scores of African-American science majors and nonscience majors. There was no significant relationship between science self-efficacy and course grade, gender and science self-efficacy score, and course withdrawal and science self-efficacy score.

    With the increasing demand for the development of more nuclear power comes the responsibility to address the technical challenges of immobilizing high-level nuclear wastes in stable solid forms for interim storage or disposition in geologic repositories. The immobilization of high-level nuclear wastes has been an active area of research and development for over 50 years. Borosilicate glasses and complex ceramic composites have been developed to meet many technical challenges and current needs, although regulatory issues, which vary widely from country to country, have yet to be resolved. Cooperative international programs to develop advanced proliferation-resistant nuclear technologies to close the nuclear fuel cycle and increase the efficiency of nuclear energy production might create new separation waste streams that could demand new concepts and materials for nuclear waste immobilization. This article reviews the current state-of-the-art understanding regarding the materials science of glasses and ceramics for the immobilization of high-level nuclear waste and excess nuclear materials and discusses approaches to address new waste streams.

    Pacific Ocean Literacy for Youth, Publics, Professionals, and Scientists (POLYPPS) is an NSF-funded collaboration between the University of Hawai`i and the Center for Ocean Science Education Excellence (COSEE) - California, which is based at the Lawrence Hall of Science, University of California - Berkeley. One of the objectives of this project is to instutionalize ocean science communications courses at colleges and universities in Hawai`i. Although the focus of most of these communications courses has been on training graduate students and scientists, lower-division students interested in the ocean sciences are finding this background helpful. At the University of Hawai`i Maui College there are several marine science courses and certificate programs that require students to interact with the public through internships, research assistantships, and course-related service-learning projects. Oceanography 270, Communicating Ocean Science, is now offered to meet the needs of these students who engage with the public in informal educational settings. Other students who enroll in this course have a general interest in the marine environment and are considering careers in K-12 formal education. This course gives this group of students an opportunity to explore formal education by assisting classroom teachers and preparing and presenting problem-based, hands-on, inquiry activities. Employers at marine-related businesses and in the tourist industry have welcomed this course with a focus on communication skills and indicate that they prefer to hire local people with strong backgrounds in marine and natural sciences. A basic premise of POLYPPS is that science education must draw not only from the latest advances in science and technology but also from the cultural contexts in which the learners are embedded and that this will achieve increased understanding and stewardship of ocean environments. Students in Oceanography 270 integrate traditional Hawaiian knowledge into their activities and presentations with the advice of local practitioners who share their experiences for incorporating both Hawaiian ways of learning and environmental practices.

    Gillham, Travis; Yannimaras, Demetrios

    1999-11-03

    The West Hackberry Tertiary Project is a field test of the concept that air injection can generate tertiary oil recovery through the Double Displacement Process. The Double Displacement Process is the gas displacement of a water invaded oil column for the purpose of recovering tertiary oil through gravity drainage. The novel aspect of this project is the use of air as the injection fluid. In Gulf Coast oil reservoirs with pronounced bed dip, reservoir performance has shown that gravity drainage recoveries average 80% to 90% of the original oil in place while water drive recoveries average 50% to 60% of the original oil in place. The target for tertiary oil recovery with the Double Displacement Process is the incremental oil between the 50% to 60% water drive recoveries and the 80% to 90% gravity drainage recoveries. The use of air injection in this process combines the benefits of air's low cost and universal accessibility with the potential for improved oil recovery resulting from spontaneous in situ combustion. If successful, this project will demonstrate that utilizing air injection in the Double Displacement Process will result in an economically viable tertiary process in many Gulf Coast oil reservoirs where other tertiary processes are presently uneconomic. The West Hackberry Tertiary Project receives matching funds from the United States Department of Energy (DOE) as part of the DOE's Class 1 Program for the development of advance recovery technologies in fluvial dominated deltaic reservoirs. In addition, the Petroleum Engineering Department at Louisiana State University (LSU) provides independent study and technology transfer.

  15. The effects of student-level and classroom-level factors on elementary students' science achievement in five countries

    NASA Astrophysics Data System (ADS)

    Kaya, Sibel

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

  18. Teachers' beliefs about science teaching and context factors: Implications for teaching and learning science at the middle school level

    NASA Astrophysics Data System (ADS)

    Pea, Celeste H.

    Current research shows that teachers' beliefs have been virtually ignored in science education reform efforts spearheaded by the development of national, state, and local standards. Since the aim of science education reform is to improve scientific literacy for all students, increasingly, researchers are questioning the lack of attention to teachers' beliefs and are calling for more research to examine teachers' beliefs and the influence of school environmental factors on their classroom practices. The purpose of this study was to explore, investigate, and analyze data that might reveal middle school science teachers' beliefs about science teaching and how school environmental factors influence their classroom behavior. The mixed methods study was conducted in a large urban/suburban county in an eastern state in the United States. Data were collected through a Likert-style survey and interview and observation sessions. Ninety-one middle school science teachers completed the survey. Three teachers from the survey sample also participated in the interview and observation sessions. The findings from the quantitative and qualitative data indicated that most of the middle school science teachers in this study believed that science teaching should be student-centered, and science instruction should be based on an inquiry-based approach to teaching and learning. They also believed that the state and county standards were the most important factors in helping teachers to use inquiry-based instructional strategies to teach science. In addition to the science standards, the middle school science teachers believed that peer and principal support were critical to their success as teachers, and that instructional materials and supplies were readily available to help them teach science. The findings from the study indicated that few school environmental factors affected the middle school teachers' classroom practices. However, time (to participate in more professional activities and to complete class work), student level of maturity to do inquiry, and students taking responsibility for their own learning were identified as school environmental factors teachers believed hindered their effectiveness as teachers. The research findings confirmed findings from earlier studies that some teachers' beliefs are inconsistent with their practices. Although most of the teachers responded or were observed using nontraditional practices, the inconsistency that was observed between some teachers' stated beliefs and their practices supports the idea that it may be difficult to achieve scientific literacy for all students. Since current science reform marks a sharp departure from the way science was taught in the past, more research is needed to help determine why this inconsistency continues to exist.

  19. Striped tertiary storage arrays

    NASA Technical Reports Server (NTRS)

    Drapeau, Ann L.

    1993-01-01

    Data stripping is a technique for increasing the throughput and reducing the response time of large access to a storage system. In striped magnetic or optical disk arrays, a single file is striped or interleaved across several disks; in a striped tape system, files are interleaved across tape cartridges. Because a striped file can be accessed by several disk drives or tape recorders in parallel, the sustained bandwidth to the file is greater than in non-striped systems, where access to the file are restricted to a single device. It is argued that applying striping to tertiary storage systems will provide needed performance and reliability benefits. The performance benefits of striping for applications using large tertiary storage systems is discussed. It will introduce commonly available tape drives and libraries, and discuss their performance limitations, especially focusing on the long latency of tape accesses. This section will also describe an event-driven tertiary storage array simulator that is being used to understand the best ways of configuring these storage arrays. The reliability problems of magnetic tape devices are discussed, and plans for modeling the overall reliability of striped tertiary storage arrays to identify the amount of error correction required are described. Finally, work being done by other members of the Sequoia group to address latency of accesses, optimizing tertiary storage arrays that perform mostly writes, and compression is discussed.

  20. Kinetics and capacities of phosphorus sorption to tertiary stage wastewater alum solids, and process implications for achieving low-level phosphorus effluents.

    2015-11-15

    The role of adsorption and/or complexation in removal of reactive or unreactive effluent phosphorus by already formed chemical precipitates or complexes has been investigated. Potential operational efficiency gains resulting from age of chemically precipitated tertiary alum sludge and the recycle of sludge to the process stream was undertaken at the Iowa Hill Water Reclamation Facility which employs the DensaDeg(Ā®) process (IDI, Richmond, VA) for tertiary chemical P removal to achieve a filtered final effluent total phosphorus concentration of <30 Ī¼g/L. The effect of sludge solids age was found to be insignificant over the solids retention time (SRT) of 2-8 days, indicating that the solids were unaffected by the aging effects of decreasing porosity and surface acidity. The bulk of solids inventory was retained in the clarifier blanket, providing no advantage in P removal from increased solids inventory at higher SRTs. When solids recycle was redirected from the traditional location of the flocculation reactor to a point just prior to chemical addition in the chemical mixing reactor, lower effluent soluble P concentrations at lower molar doses of aluminum were achieved. At laboratory scale, the "spent" or "waste" chemical alum sludge from P removal showed high capacity and rapid kinetics for P sorption from real wastewater effluents. Saturation concentrations were in the range of 8-29 mg soluble reactive P/g solids. Higher saturation concentrations were found at higher temperatures. Alum sludge produced without a coagulant aid polymer had a much higher capacity for P sorption than polymer containing alum sludge. The adsorption reaction reached equilibrium in less than 10 min with 50% or greater removal within the first minute. PMID:26331896

    Aside from its value as an aid in determining the age of Tertiary beds, the chief interest of the genus Clementia lies in the anomalous features of its present and former distribution. An attempt is made in this paper to trace its geologic history, to point out its paleobiologic significance, and to describe all the known American Tertiary species. The fossils from Colombia used in preparing this report were collected during explorations made under the direction of Dr. 0. B. Hopkins, chief geologist of the Imperial Oil Co. (Ltd.), who kindly donated them to the United States National Museum. Dr. T. Wayland Vaughan, of the Scripps Institution of Oceanography, furnished information relating to specimens collected by him in Mexico. Dr. Bruce L. Clark, of the University of California; Dr. G. Dallas Hanna, of the California Academy of Sciences; Dr. H. A. Pilsbry, of the Philadelphia Academy of Natural Sciences; and Dr. W. D. Matthew, of the American Museum of Natural History, generously loaned type specimens and other material. Doctor Clark and Doctor Hanna also gave information concerning the Tertiary species from California. Mr. Ralph B.

    The editorial process is analyzed, and five levels of edit are identified. These levels represent cumulative combinations of nine types of edit: (1) coordination, (2) policy, (3) integrity, (4) screening, (5) copy clarification, (6) Mechanical Style, (7) Language, and (9) substantive. The levels and types of edit, although developed for specific use with external reports at the Jet Propulsion Laboratory, cover the general range of technical editing, especially as it applies to an in-house technical publications organization. Each type of edit is set forth in terms of groups of actions to be performed by the editor. The edit-level concept has enhanced understanding and communication among editors, authors, and publications managers concerning the specific editorial work to be done on each manuscript. It has also proved useful as a management tool for estimating and monitoring cost.

  3. An investigation of children's levels of inquiry in an informal science setting

    Clark-Thomas, Beth Anne

    Elementary school students' understanding of both science content and processes are enhanced by the higher level thinking associated with inquiry-based science investigations. Informal science setting personnel, elementary school teachers, and curriculum specialists charged with designing inquiry-based investigations would be well served by an understanding of the varying influence of certain present factors upon the students' willingness and ability to delve into such higher level inquiries. This study examined young children's use of inquiry-based materials and factors which may influence the level of inquiry they engaged in during informal science activities. An informal science setting was selected as the context for the examination of student inquiry behaviors because of the rich inquiry-based environment present at the site and the benefits previously noted in the research regarding the impact of informal science settings upon the construction of knowledge in science. The study revealed several patterns of behavior among children when they are engaged in inquiry-based activities at informal science exhibits. These repeated behaviors varied in the children's apparent purposeful use of the materials at the exhibits. These levels of inquiry behavior were taxonomically defined as high/medium/low within this study utilizing a researcher-developed tool. Furthermore, in this study adult interventions, questions, or prompting were found to impact the level of inquiry engaged in by the children. This study revealed that higher levels of inquiry were preceded by task directed and physical feature prompts. Moreover, the levels of inquiry behaviors were haltered, even lowered, when preceded by a prompt that focused on a science content or concept question. Results of this study have implications for the enhancement of inquiry-based science activities in elementary schools as well as in informal science settings. These findings have significance for all science educators, in both formal and informal settings, with regard to ways in which higher level inquiry could be facilitated and ways in which volunteers could engage visitors with open-ended exhibits at informal science settings. Moreover, the study presents implications for the development of specific interventions through adults' administration of questions as prompts designed to assist children in reaching greater levels of inquiry.

    During the Tertiary, Spain suffered compressional collision between France and Africa, and its Atlantic and Mediterranean coasts have been further modified by extensional rifting. Because it includes sectors of two separate foreland basins, and an intervening craton with basins that have been influenced by extensional and strikeSHslip deformation, Spain provides excellent material for the development and testing of theories on the study of sedimentary basin formation and filling. This book is one of the few studies available in English of the important Tertiary geology of Spain.

  13. Evaluation of constructivist pedagogy: Influence on critical thinking skills, science fair participation and level of performance

    NASA Astrophysics Data System (ADS)

    Foxx, Robbie Evelyn

    Science education reform, driven by a rapidly advancing technological society, demands the attention of both elementary and middle school curriculum-developers. Science education training in current standards (National Research Council [NRC] Standards 1996) emphasize inquiry, which is reported to be a basic tenet of the theory known as constructivism (NAASP, 1996; Cohen, 1988; Conley, 1993; Friedman, 1999; Newman, Marks, & Gamoran, 1996; Smerdon & Burkam 1999; Sizer 1992; Talbert & McLaughlin 1993; Tobin & Gallagher, 1987; Yager, 1991, 2000). Pedagogy focusing on the tenets of constructivist theory, at the intermediate level, can address current science standards. Many science educators believe participation in science fairs helps students develop the attitudes, skills, and knowledge that will help them to be comfortable and successful in the scientific and technological society (Czerniak, 1996). Competing in science fairs is one vehicle which allows students to apply science to societal issues, solve problems and model those things scientists do. Moreover, constructing a science fair project is suggested as being an excellent means to foster the development of concepts necessary in promoting scientific literacy (Czerniak, 1996). Research further suggests that through science fairs or other inquiry activities, students construct their knowledge with fewer misconceptions as they explore and discover the nature of science (NRC 1996). Tohn 's study (as cited in Bellipanni, 1994) stated that science fairs are a major campaign to increase student skills and to allow students a chance to have fun with science. The purpose of this research was twofold: (1) to assess science problem solving skills of students instructed using constructivist pedagogy, and (2) to explore the effects of constructivist pedagogy's influence(s) on science fair participation/placement. Students' attitudes resulting from these experiences were examined as well.

  14. An instructional package integrating science and social studies instruction at the fifth-grade level

    NASA Astrophysics Data System (ADS)

    Hulley, Kathy Louise Sullivan

    Integrative education is being implemented by classroom teachers who want to immerse students in an environment rich in problem-solving skills, critical analysis skills, ethics, valuing of knowledge, and communication of learning. Several subject areas in the curriculum have been integrated, such as literature with social studies and mathematics with science. The focus of this dissertation is on the integration of science and social studies at the fifth grade level using the Mississippi State Department of Education Curriculum Guidelines and Objectives (MSDE, 1995) and the National Science Education Standards (National Research Council (NRC), 1996). An instructional package of lesson plans that teachers can use as ideas to create their own plans for an integrated curriculum of science and social studies was devised. The Mississippi State Department of Education Curriculum Guidelines and Objectives for Social Studies (MSDE, 1995) at the fifth grade level contain fifteen competencies. Three standards from the National Science Education Standards (NRC, 1996) were chosen. They include (a) science and technology, (b) science in personal and social perspectives, and (c) the history and nature of science. Each competency for social studies has three lesson plans written that integrate the three chosen standards from the National Science Education Standards. A total of forty-five lesson plans were written integrating science and social studies. Each lesson plan includes an objective, materials, procedures, and evaluation for teachers. Teachers are encouraged to use the lesson plans as a guide in creating their own lesson plans that would correspond to their school's particular curriculum guidelines. Consideration should be given to the learning levels and styles of their classroom. This qualitative study was done to create lesson plans that integrate science and social studies with the hope that teachers will expand upon them and implement them into their curricula.

  19. Tertiary gain and disability syndromes.

    Kwan, O; Ferrari, R; Friel, J

    2001-10-01

    Since the introduction of the concept of tertiary gain by Dansak in 1973, there has been little further publication or research on this topic. Yet, tertiary gain is often the subject of debate amongst physicians, therapists, insurers, the media, and even at times the general public. Much of the controversy of disability syndromes and the health and economic burden they present has focused on secondary gain and illness behaviour. The role of tertiary gain in illness behaviour is likely also relevant, and a model of tertiary gain is needed to begin further understanding the implications of this phenomenon for patients and those who treat them. This article introduces a phraseology for tertiary gain, and models the effects of tertiary gain on illness behaviour and the interactions of secondary and tertiary gain in the setting of disability syndromes.

  6. Differential workload calculation and its impact on lab science instruction at the community college level

    NASA Astrophysics Data System (ADS)

    Boyd, Beth Nichols

    The calculation of workload for science instructors who teach classes with laboratory components at the community college level is inconsistent. Despite recommendations from the National Research Council (1996) and the large body of evidence which indicates that activity-based instruction produces greater learning gains than passive, lecture-based instruction, many community colleges assign less value to the time spent in science lab than in lecture in workload calculations. This discrepancy is inconsistent with both current state and nation-wide goals of science excellence and the standards set by the American Chemical Society (2009) and the American Association of Physics Teachers (2002). One implication of this differential lab-loading policy is that the science instructors must teach more hours per week to make the same workload as their colleagues in other disciplines which have no formal laboratory activities. Prior to this study, there was no aggregate data regarding the extent of this policy at the community college level nor of its possible impact upon instruction. The input of full-time two-year college members of four different professional science organizations was solicited and from their responses, it is clear that differential loading of lab hours is common and widely variable. A majority of the respondents to this study had their hours in lab assigned less credit than their hours in lecture, with multiple perceived impacts upon lab preparation, assistance, revision, and follow-up activities. In combination with open-ended comments made by study participants, the results suggest that science instructors do perceive impacts upon their ability to teach science labs in a pedagogically current and challenging manner when their hours spent in lab instruction are counted for less than their hours in lecture. It is hoped that the information from this study will be used to implement improvements in the working conditions needed to advance science instruction and student science outcomes at the community college level.

  7. The effectiveness of take-home science kits at the elementary level

    NASA Astrophysics Data System (ADS)

    Gennaro, Eugene; Lawrenz, Frances

    A major reason for the lack of scientific and technological literacy in this country is the lack of emphasis on high-quality science education at the elementary school level. The National Science Board Commission on Precollege Education in Mathematics, Science, and Technology states in its report (1983) that formal study of science must be reinforced by a wide range of activities outside the school. Learning in the home appears to be an excellent way to enhance elementary school science programs. Students who study with their parents or whose parents are involved in school activities achieve more in school. This study describes and presents evaluation data for a program that encourages elementary school students and their parents to study science topics in a hands-on, inquiry fashion in their own homes. The analyses of the data indicate that the program is viewed very positively by both the students and their parents, that there are gender and grade-level differences in the students, and that the program seems to be more effective for girls, a group at risk for continuing in science.

  11. West Hackberry Tertiary Project

    SciTech Connect

    Kenneth Haley; Travis Gillham; Demetrios Yannimaras

    1999-03-31

    The West Hackberry Tertiary Project is a field test of the concept that air injection can be combined with the Double Displacement Process to produce a tertiary recovery process that is both low cost and economic at current oil prices. The Double Displacement Process is the gas displacement of a water invaded oil column for the purpose of recovering tertiary oil by gravity drainage. In reservoirs with pronounced bed dip such as those found in West Hackberry and other Gulf Coast salt dome fields, reservoir performance has shown that gravity drainage recoveries average 80% to 90% of the original oil in place while waterdrive recoveries average 50% to 60% of the original oil in place. The target for tertiary oil recovery in the Double Displacement Process is the incremental oil between the 50% to 60% waterdrive recoveries and the 80% to 90% gravity drainage recoveries. In previous field tests, the Double Displacement Process has proven successful in generating tertiary oil recovery. The use of air injection in this process combines the benefits of air's low cost and universal accessibility with the potential for accelerated oil recovery from the combustion process. If successful, this project will demonstrate that utilizing air injection in the Double Displacement Process will result in an economically viable tertiary process in reservoirs (such as Gulf Coast salt dome reservoirs) where any other tertiary process is presently uneconomic. Air injection on the West Hank began in November of 1994. Although West Flank air injection has increased reservoir pressure by 500 pounds per square inch (psi), production response has not yet occurred. The gas cap on the West Flank has not expanded sufficiently to push the oil rim down to the nearest down structure well. Cumulative injection to date is 1.6 BCF, only approximately 50% of the projected volume required to establish oil production response. Additional air injection is required to further expand the gas cap and thereby bring about oil production. Air injection rates have been restricted due to iron oxide plugging in the injectors. To spread risk among multiple reservoirs, the project was expanded in 1996 to include air injection in low pressure reservoirs on the North Flank of the field. The project reservoirs on the West Flank are much higher pressure (2500-3300 psi) than the project reservoirs on the North Flank (300-600 psi). Air injection began on the North Rank in July of 1996. While West Flank air injection has not yet yielded oil production, air injection has increased oil production in all three low pressure North Hank reservoirs. Production increased in the North Rank after only two months of air injection, much quicker than anticipated. Between July of 1996 and July of 1999, cumulative air injection of 0.9 BCF increased North Flank oil production by 224,000 barrels above the normal decline. As of July, 1999, air injection was generating 270 barrels of oil per day (BOPD) of incremental oil production from the three low pressure reservoirs on the North Flank of the field.

  12. Comparing scientists' views of nature of science within and across disciplines, and levels of expertise

    NASA Astrophysics Data System (ADS)

    Tira, Praweena

    2009-12-01

    The purpose of this study was to understand how Thai scientists from four disciplines viewed nature of science (NOS). The sixteen participating scientists were chosen from the areas of chemistry, physics, biology/life sciences, and geology/earth sciences and were separated into novice and expert groups. The scientists' understandings about NOS were compared within and among the science groups as well as within and between novices and experts. All participants in the study had an opportunity to voice their opinions about the seven aspects of NOS that science educators in the United States have agreed should be taught in K-12 science classrooms. The scientists' views were found to be neither informed nor naive but were a mix between the two. Many scientists' responses showed more naive views with respect to tentativeness, subjectivity, social and cultural embeddedness, and the relationship between scientific theories and laws. The scientists' views about NOS differed with few observable patterns within or across disciplines. The novices' and experts' views of aspects of NOS were not substantially different. The scientists from both groups generally shared mixed viewpoints. Even though a few discipline specific patterns emerged from this study, cross disciplinary aspects of NOS in integrated science instruction is suggested rather than establishing particular concepts of NOS for each discipline so as to reduce complexity. Representatives of both novice and expert groups might be recruited to participate in developing new science curricula, teaching materials, and science teacher training programs. In addition, other factors need to be considered such as their knowledge of NOS, their willingness to get involved in science education at the school level or teacher education program, and their willingness to cooperate in the multi-step tasks of curriculum development.

    2003-12-01

    Mathematics at matriculation level (Grade 12) is one of the subjects required for admission to the Veterinary Nursing Diploma in the Faculty at Veterinary Science of the University of Pretoria. The present study shows that there is no statistically significant relationship between the grade of mathematics at matriculation level and the success or failure in the 1st year of study. There is, however, a statistical difference in the adjusted mark obtained for mathematics at matriculation level between the groups that passed and failed the 1st year of the veterinary nursing course. The results of this research are not consistent with other research which showed that secondary school mathematics results are not a significant factor in tertiary education. It is recommended that selection criteria for veterinary nurses should in future still include mathematics, but that cognisance should be taken of the mark obtained and students with higher marks (above 57%) given preference.

  15. A substantive-level theory of highly regarded secondary biology teachers' science teaching orientations

    NASA Astrophysics Data System (ADS)

    Friedrichsen, Patricia Jean

    Pedagogical content knowledge (PCK) has been used as a heuristic for examining a specialized knowledge base for teaching. One proposed overarching component within the PCK model for science teaching is teaching orientations, defined as teachers' knowledge and beliefs about the purposes and goals for teaching science at a particular grade level. Nine different orientations to teaching science have been identified in the science education literature, yet there are few empirical studies specifically examining science teachers' orientations. This qualitative case study re-examines science teaching orientations using grounded theory methods. The study focused on the nature and sources of the science teaching orientations held by four highly-regarded secondary biology teachers. Data collection consisted of a card-sorting task, semi-structured interviews, and classroom observations. Inductive data analysis led to the construction of a substantive-level theory of science teaching orientations. In regard to the nature of science teaching orientations, the use of central and peripheral goals, as well as the means of achieving these goals, better represents the complex nature of science teaching orientations. Although the participants were secondary biology teachers, they held more general teaching orientations than science-specific orientations. The participants held goals in the affective domain, e.g., the development of positive attitudes toward biology, as well as general schooling goals, including preparing students for college and the development of life skills. Although each participant held science content goals, these goals were not always a central component of their teaching orientation. In addition, goals and purposes shape the means that a teacher chooses, but a limited repertoire of means can also restrict the teacher's purposes and goals. In regard to the sources of teaching orientations, participants were influenced by a multitude of factors, including prior work experiences and professional development. Professional development served as a feedback loop, as participants selected professional development that re-enforced their teaching orientation. The school context, with its perceived time constraints, was another contributing factor. The participants' teaching orientations were strongly influenced by their daily interactions with students. The teachers' beliefs about learners and learning were major sources of their teaching orientations. Implications are given for practice, research and policy.

  16. Predictors of gender achievement in physical science at the secondary level

    NASA Astrophysics Data System (ADS)

    Kozlenko, Brittany Hunter

    This study used the 2009 National Assessment of Educational Progress (NAEP) science restricted data-set for twelfth graders. The NAEP data used in this research study is derived from a sample group of 11,100 twelfth grade students that represented a national population of over 3,000,000 twelfth grade students enrolled in science in the United States in 2009. The researcher chose the NAEP data set because it provided a national sample using uniform questions. This study investigated how the factors of socioeconomic status (SES), parental education level, mode of instruction, and affective disposition affect twelfth grade students' physical science achievement levels in school for the sample population and subgroups for gender. The factors mode of instruction and affective disposition were built through factor analysis based on available questions from the student surveys. All four factors were found to be significant predictors of physical science achievement for the sample population. NAEP exams are administered to a national sample that represents the population of American students enrolled in public and private schools. This was a non-experimental study that adds to the literature on factors that impact physical science for both genders. A gender gap is essentially nonexistent at the fourth grade level but appears at the eighth grade level in science based on information from NAEP (NCES, 1997). The results of the study can be used to make recommendation for policy change to diminish this gender gap in the future. Educators need to be using research to make instructional decisions; research-based instruction helps all students.

  12. An initial needs assessment of science inquiry curriculum practices at a local level

    NASA Astrophysics Data System (ADS)

    Cottingham, Susan M.

    Frequently, students learn in science classes taught like traditional reading courses in which reading texts and answering questions is the main activity. The problem at one southern middle school is that students are not developing an understanding of science concepts and are doing poorly on standardized testing. Students are seldom given the opportunity model scientific inquiry methods that promote experiential learning in the classroom. The purpose of this project was to create a curriculum for inquiry science (IS) instruction at the seventh-grade level to increase student understanding of science concepts after conducting an initial needs assessment to guide deploying the intervention. Research guiding the IS movement at the national level suggests that many teachers use only the textbook and students do not apply what they have learned. Factors affecting this problem include a lack of integrated curricula for IS learning and teacher understanding and confidence in IS skills. A constructivist view of student learning served as the conceptual framework. The needs analysis for the project questioned if teachers were willing to adopt the IS method and prepared to conduct it through a quantitative survey research design. Results indicated that all teachers supported the IS approach, however it was infrequently used in instruction and only two of five teachers were somewhat comfortable with their IS skills. The local IS project draws from empirically tested elements to develop an integrated IS curricula aligned to the state science criterion. The curricula will be supported through a concurrently deployed professional learning community to support teacher professional development and confidence. This project can positively impact social change by increasing science related academic performance, and ultimately, interest in careers in science among middle school students.

  13. Ethiopian Tertiary dike swarms

    NASA Technical Reports Server (NTRS)

    Mohr, P. A.

    1971-01-01

    Mapping of the Ethiopian rift and Afar margins revealed the existence of Tertiary dike swarms. The structural relations of these swarms and the fed lava pile to monoclinal warping of the margins partly reflect a style of continental margin tectonics found in other parts of the world. In Ethiopia, however, conjugate dike trends appear to be unusually strongly developed. Relation of dikes to subsequent margin faulting is ambiguous, and there are instances where the two phenomena are spatially separate and of differing trends. There is no evidence for lateral migration with time of dike injection toward the rift zone. No separate impingement of Red Sea, Gulf of Aden, and African rift system stress fields on the Ethiopian region can be demonstrated from the Tertiary dike swarms. Rather, a single, regional paleostress field existed, suggestive of a focus beneath the central Ethiopian plateau. This stress field was dominated by tension: there is no cogent evidence for shearing along the rift margins. A gentle compression along the rift floor is indicated. A peculiar sympathy of dike hade directions at given localities is evident.

    This paper highlights the results of long-term collaborations between the University of South Florida's College of Marine Science (CMS) and the Pinellas County school district (22nd largest nationally) to advance and improve K-12 Earth/Ocean science education. The 12-year mission of Education and Public Outreach (EPO) in the College of Marine Science has been to meaningfully integrate ocean science research and science learning to enhance K-12 education for teachers and students. Our interactive and interdisciplinary programs include research cruises, field trips, authentic research projects, satellite broadcasts, and web-based technologies. This paper will focus on two programs, the Oceanography Camp for Girls and Teachers and Project Oceanography. We will address impact of these programs, what works, the role and value of partnerships, sustainability and future initiatives. An especially critical aspect of EPO is partnerships. Our partners include people, scientific facilities, community, and donors. Financial partnerships provide sustainability and continuity. For example, private donors have built a series of endowments to support the Oceanography Camp for Girls currently valued at over \\$1 million. Given the recent shift in state and federal funding priorities, private funding is a vital element of successful EPO programs. To date, marine science EPO partnerships have included 34 state agencies, universities, private research laboratories, schools, and museums; 75 scientist, advanced graduate students and teachers as co-instructors; 4 television stations and 2 production companies; and over 2,000,000 participants in 7 countries. Multi-level partnerships are enhancing K-12 classrooms around the world with relevant ocean science content and resources to further science interests, ocean awareness, and informed decision making.

    Objectives: Recent guidelines for estimation of glucose recommend the use of citrate buffer tubes to inhibit glycolysis if the sample cannot be cooled immediately and separated within 30 min. These tubes are currently not available in India. We prepared the citrate tubes and compared the glucose results obtained with sodium fluoride tubes. Methods: Random blood samples of 44 apparently healthy volunteers were collected in three pairs of citrate buffer and sodium fluoride tubes during September to October 2013. They were labeled as 0 h, 1 h and 2 h samples indicating a delay in centrifugation to separate plasma. Glucose was analyzed on the fully auto analyzer in duplicates using glucose oxidase-peroxidase method. Results: The mean glucose concentrations at 0 h in citrate tubes were 105.8 Ā± 19.5 mg/dl compared to 99.6 Ā± 18.3 mg/dl in sodium fluoride tube. There was statistically significant difference in the glucose levels measured in plasma separated from citrate buffer tube and sodium fluoride tube at 0 h, 1 h, and 2 h. The difference between citrate and sodium fluoride tube results ranged from 6.1 mg/dl at 0 h to 7.4 mg/dl at 2 h. Glucose levels decreased significantly at 2 h in both citrate and sodium fluoride tubes. Conclusion: There is a significant decrease in glucose levels in sodium fluoride tubes even with immediate separation of plasma. There is urgent need to standardize the preanalytical conditions for glucose estimation so that effective inhibition of glycolysis can be done. PMID:26958523

  1. Tertiary ice sheet dynamics: The Snow Gun Hypothesis

    NASA Astrophysics Data System (ADS)

    Prentice, M. L.; Matthews, R. K.

    1991-04-01

    We observe strong negative correlation between Tertiary low- to mid-latitude planktonic foraminiferal ?18O and the difference between these data and coeval benthic foraminiferal ?18O. Late Quaternary data do not show this correlation. Coupling statistical model/?18O comparisons and evidence for Antarctic ice and ocean temperature variation, we infer that Tertiary ice volume, recorded by tropical planktonic ?18O, increased as the deep ocean warmed. Because the isotopic signatures of deepwater temperature variation and ice volume change were of opposite sign, the sum of these signals in Tertiary benthic ?18O became lost in the noise. This renders low correlation between Tertiary planktonic and benthic ?18O time series compared to late Quaternary data. We contend that Tertiary ice sheet growth was commonly driven by warming of deep water from low- to mid-latitude marginal seas (snow gun hypothesis). In contrast, late Quaternary ice sheets grew as deep water, formed at high latitude, cooled. Because tectonic forcing and orbital forcing at low-latitude primarily controlled production and temperature variations of this Warm Saline Deep Water, these influences largely dictated Tertiary ice volume fluctuations. Through the Tertiary, we infer ice volume fluctuations to be an important component of sea level history on timescales between 103 and 107 years.

    2011-01-01

    Our study, focused on classroom-based research at the introductory level and using the Phage Genomics course as the model, shows evidence that first-year students doing research learn the process of science as well as how scientists practice science. A preliminary but notable outcome of our work, which is based on a small sample, is the change in student interest in considering different career choices such as graduate education and science in general. This is particularly notable, as previous research has described research internships as clarifying or confirming rather than changing undergraduatesā€™ decisions to pursue graduate education. We hypothesize that our results differ from previous studies of the impact of engaging in research because the students in our study are still in the early stages of their undergraduate careers. Our work builds upon the classroom-based research movement and should be viewed as encouraging to the Vision and Change in Undergraduate Biology Education movement advocated by the American Association for the Advancement of Science, the National Science Foundation, and other undergraduate education stakeholders.

    In recent years, the geoscience community around the world has been faced with a new series of critical problems associated with the management of waste and protection of the environment. One of the most pressing issues facing our civilization today is the production of enough science capability in geology, hydrogeology, engineering, and biology to meet the demand for the solution of these problems. Many countries are developing special programs similar to those in the United States of the National Academy of sciences, American Geological Institute, Geological Society of America, and the American Association of Petroleum Geologists. The editors of Environmental Geology have decided to begin a series of articles for the “Views and News” section of the journal on programs of this type being implemented around the world. The first of this series is by geoscientist Breda Naughton, Assistant Chief Executive for the National Council for Curriculum and Assessment, titled “Science Education in the Republic of Ireland: At First and Second Levels,” which follows. The overall education policy of the National Council for Curriculum and Assessment (NCCA) for first and second level education is to provide a balanced education for our young people which will contribute to their full development as individuals and give them the knowledge, skills, and competencies that will enable them to live productive and creative lives. Science is seen as an essential component of such an education in today's world.

    Based on conceptual change theory, cognitive conflict is known as an important factor in conceptual change even though there are still questions about its positive and negative effects on science learning. However, there is no reliable method by which to assess the cognitive conflict students experience in their learning. The purpose of this research was to develop an instrument for measuring secondary students' cognitive conflict levels as they learned science. The results of this study indicate that our instrument is a valid and reliable tool for measuring cognitive conflict levels. Factor analysis supported the model that cognitive conflict consists of four constructs: recognition of an anomalous situation, interest, anxiety, and cognitive reappraisal of the conflict situation. Implications for instruction and possibilities for future research are discussed.

    2013-12-01

    Explanations involving submicro levels of representation are central to science education, but known to be difficult for students in secondary school. This study examines students' written explanations of physical and chemical phenomena regarding matter and changes in matter, in a large-scale test. This is done in order to understand linguistic challenges in constructing submicro level explanations involving the particle model of matter. Drawing from systemic functional linguistics, the lexicogrammatics used in explanations for realising experiential meaning in student explanations were analysed. We used answers to two partly constructed response items from the Swedish part of Trends in International Mathematics and Science Studies 2007, grade 8, to sort out explanations referring to the particle model of matter. These answers (86 from 954) were analysed regarding choices of vocabulary and grammar to distinguish between macro and submicro level of representation. The results show that students use a wide variety of lexicogrammatical resources to realise what happens on both macro and submicro level of representation, with greater diversity of verbs on the submicro level of explanation. The results suggest an uncertainty about the distinction between macro and submicro level of explanation.

  9. Pedagogical Reflections by Secondary Science Teachers at Different NOS Implementation Levels

    NASA Astrophysics Data System (ADS)

    Herman, Benjamin C.; Clough, Michael P.; Olson, Joanne K.

    2015-10-01

    This study investigated what 13 secondary science teachers at various nature of science (NOS) instruction implementation levels talked about when they reflected on their teaching. We then determined if differences exist in the quality of those reflections between high, medium, and low NOS implementers. This study sought to answer the following questions: (1) What do teachers talk about when asked general questions about their pedagogy and NOS pedagogy and (2) what qualitative differences, if any, exist within variables across teachers of varying NOS implementation levels? Evidence derived from these teachers' reflections indicated that self-efficacy and perceptions of general importance for NOS instruction were poor indicators of NOS implementation. However, several factors were associated with the extent that these teachers implemented NOS instruction, including the utility value they hold for NOS teaching, considerations of how people learn, understanding of NOS pedagogy, and their ability to accurately and deeply self-reflect about teaching. Notably, those teachers who effectively implemented the NOS at higher levels value NOS instruction for reasons that transcend immediate instructional objectives. That is, they value teaching NOS for achieving compelling ends realized long after formal schooling (e.g., lifelong socioscientific decision-making for civic reasons), and they deeply reflect about how to teach NOS by drawing from research about how people learn. Low NOS implementers' simplistic notions and reflections about teaching and learning appeared to be impeding factors to accurate and consistent NOS implementation. This study has implications for science teacher education efforts that promote NOS instruction.

  10. Tertiary serpentinite tectonics in northern Hispaniola

    SciTech Connect

    Nagle, F.; Draper, G.

    1985-01-01

    At least 4 types of serpentinite bodies are found in N. Hispaniola, by different inclusion and Tertiary deformation styles: (1) Narrow slivers occurring on Tertiary faults, rarely containing inclusions, which occur throughout the region. (2) Massive fractured serpentinites associated with a Cretaceous volcanic plutonic and metamorphic basement, and containing rodingite dikes, occurs in the Puerto Plata region. (3) Massive, fractured, but coherent bodies containing Tertiary limestone clasts which apparently the same as nearby limestone overlying the serpentinite occur west of Puerto Plata. (4) Diapirically emplaced bodies in the Gaspar Hernandez region containing both brecciated and massive zones and containing a variety of inclusions. Type 4 bodies protrude into the clastic Upper Eocene Altamira Fm. The most common tectonic inclusions in these bodies are rounded cobbles of diorite and gabbro. Amphibolites are also common, but friable greenschists and blueschists are rare, as are blocks of clastic sediments. The authors suggest that large blocks of the Altamira Fm. were incorporated into the serpentinite during their past Eocene diapirism and that these blocks were deformed in a brittle manner into gouge zones by internal movements in the diapir. Type 4 serpentinites may therefore have incorporated inclusions at high crustal levels by brittle processes. Type 2 bodies, in contrast, may have incorporated inclusions by ductile flow of serpentinite at lower crustal levels. Type 33 bodies are the most enigmatic. They may be sedimentary, but alternatively may have incorporated limestone in a gouge (as for type 4), which has later healed to a coherent mass.

    The Hubble Space Telescope Frontier Fields program is a large Director's Discretionary program of 840 orbits, to obtain ultra-deep observations of six strong lensing clusters of galaxies, together with parallel deep blank fields, probing the most distant galaxies currently observable. HST observations for this program have so far been obtained on Abell 2744, MACS J0416.1-2403, MACS J0717.5+3745 and MACS J1149.5+2223, with ACS (F435W, F606W, F814W) and WFC3/IR (F105W, F125W, F140W, F160W) on both the main cluster and the parallel field in each case, while the remaining two clusters are scheduled to be completed within the next year. The high-level science data products are presented here, including all the full-depth distortion-corrected mosaics and associated products for each cluster, which are science-ready to facilitate the construction of lensing models as well as enabling a wide range of other science projects. Many improvements beyond default calibration for ACS and WFC3/IR are implemented in these data products, as well as improvements in astrometric alignment to achieve milliarcsecond-level accuracy. The resulting high-level science products are delivered via the Mikulski Archive for Space Telescopes (MAST) to the community on a rapid timescale to enable the widest scientific use of these data, as well as ensuring a public legacy dataset of the highest possible quality that is of lasting value to the entire community.

    Learning science requires higher-level (critical) thinking skills that need to be practiced in science classes. This study tested the effect of exam format on critical-thinking skills. Multiple-choice (MC) testing is common in introductory science courses, and students in these classes tend to associate memorization with MC questions and may not see the need to modify their study strategies for critical thinking, because the MC exam format has not changed. To test the effect of exam format, I used two sections of an introductory biology class. One section was assessed with exams in the traditional MC format, the other section was assessed with both MC and constructed-response (CR) questions. The mixed exam format was correlated with significantly more cognitively active study behaviors and a significantly better performance on the cumulative final exam (after accounting for grade point average and gender). There was also less gender-bias in the CR answers. This suggests that the MC-only exam format indeed hinders critical thinking in introductory science classes. Introducing CR questions encouraged students to learn more and to be better critical thinkers and reduced gender bias. However, student resistance increased as students adjusted their perceptions of their own critical-thinking abilities. PMID:22949426

  16. Deciphering the impact of sea-level changes and tectonic movement on erosional sequence boundaries in carbonate successions: A case study from Tertiary strata on Grand Cayman and Cayman Brac, British West Indies

    The stratigraphic architecture of carbonate successions that develop on geographically isolated islands reflects the balance between sea-level highstands, lowstands, and tectonic activity. This is readily apparent in the Tertiary carbonate sequences on the Cayman Islands that are formed of the Bluff Group, which includes the Brac Formation (Lower Oligocene), Cayman Formation (Middle Miocene), and Pedro Castle Formation (Middle Pliocene). These strata are overlain by the Pleistocene Ironshore Formation. The unconformities that define the boundaries between these formations are variable because some developed during one cycle of past erosion, others developed through two or more past erosional cycles, and some are still developing today. Some unconformities, like the one at the top of the Cayman Formation, are geographically variable because they underwent different developmental histories in different areas. The challenge with architectural complex successions, like those on the Cayman Islands, is that of deciphering the impact of sea-level changes as opposed to tectonic influences. During sea-level lowstands, the older carbonate successions were exposed on land and modified by surface and subsurface karst development. At the same time, marine erosional processes affected the coastal areas. Surface karst modification, which commonly produced rugged topographies with erosional relief at least 62 m, was controlled largely by rainfall, runoff, and stratal dip. Weathering on Grand Cayman at the end of the Miocene, for example, produced a dish-shaped topography with elevated peripheral rims. In contrast, uplift of the east end of Cayman Brac between the Late Pliocene (3.6 Ma) and ~ 400 ka, elevated the basal part of the Cayman Formation 33 m above sea level. Subsequent karst development, which is still ongoing today, removed most of the Cayman Formation on the eastern part of the island and produced peripheral rims that are higher than those on Grand Cayman. During some lowstands, like that between the Late Pliocene and ~ 400 ka, coeval coastal erosion led to the development of coastal benches that cut into the older carbonate strata. The combination of karst development in the islands' interiors and coastal erosion produced complex, rugged topographies that strongly influenced patterns of deposition during the following highstand. The complex stratigraphic architecture of the carbonate successions on the Cayman Islands reflects the variable impact of tectonics, karst development, and coastal erosion that was associated with each lowstand-highstand cycle.

  17. Moving toward equitable, systemic science education reform: The synergy among science education and school-level reforms in an urban middle school

    Kelly, Mary Kathryn

    The purpose of this study was to develop an understanding of the relationships among school-level and science education reform efforts and how, collectively, they contribute to the progress of equitable, systemic science education reform. A case study research design was employed to gather both qualitative and quantitative data between 1995 and 1999. The site of this study is a non-selective, urban middle school in a large district that participated in several reform efforts. These reforms include both efforts focused on school-level change and efforts focused on change in science teaching and learning. Its program incorporates aspects of several school-level reforms---from the underlying Paideia philosophy, to structural characteristics of middle schools, to site-based decision-making, to its status as a magnet school, to its participation as a professional development school. Further, the participation of all science teachers in the intensive, standards-based professional development offered by Ohio's systemic reform of mathematics and science created a critical mass of reform-oriented teachers who supported one another as they incorporated reform-based practices into their teaching. The interplay of the reform efforts has manifested in a high level of science achievement in comparison to the school's district. Addressing the third component of O'Day and Smith's model for systemic reform, the need for school-level change to enable implementation of curriculum frameworks and aligned policies, this study illustrates two important points. First, the high-quality teacher professional development increased teachers' capacity to change their practices by enhancing their knowledge of and skills in implementing standards-based teaching practices. Second, because of the synchrony among the school-level reforms and between the school-level and science education reforms, the context of Webster provided a supportive environment in which lasting changes in science teaching and learning were implemented. Science education reform efforts were mediated by the school's context to create an environment in which the reform practices could be implemented and sustained. Using Kahle's (1998) Equity Metric, this study demonstrates that the synergy of the policies and practices of school-level and science education reforms can contribute to the progress of equitable, systemic science education reform.

  18. The Science-Policy Link: Stakeholder Reactions to the Uncertainties of Future Sea Level Rise

    2011-12-01

    Policy makers and stakeholders in the coastal zone are equally challenged by the risk of an anticipated rise of coastal Local Sea Level (LSL) as a consequence of future global warming. Many low-lying and often densely populated coastal areas are under risk of increased inundation. More than 40% of the global population is living in or near the coastal zone and this fraction is steadily increasing. A rise in LSL will increase the vulnerability of coastal infrastructure and population dramatically, with potentially devastating consequences for the global economy, society, and environment. Policy makers are faced with a trade-off between imposing today the often very high costs of coastal protection and adaptation upon national economies and leaving the costs of potential major disasters to future generations. They are in need of actionable information that provides guidance for the development of coastal zones resilient to future sea level changes. Part of this actionable information comes from risk and vulnerability assessments, which require information on future LSL changes as input. In most cases, a deterministic approach has been applied based on predictions of the plausible range of future LSL trajectories as input. However, there is little consensus in the scientific community on how these trajectories should be determined, and what the boundaries of the plausible range are. Over the last few years, many publications in Science, Nature and other peer-reviewed scientific journals have revealed a broad range of possible futures and significant epistemic uncertainties and gaps concerning LSL changes. Based on the somewhat diffuse science input, policy and decision makers have made rather different choices for mitigation and adaptation in cases such as Venice, The Netherlands, New York City, and the San Francisco Bay area. Replacing the deterministic, prediction-based approach with a statistical one that fully accounts for the uncertainties and epistemic gaps would provide a different kind of science input to policy makers and stakeholders. Like in many other insurance problems (for example, earthquakes), where deterministic predictions are not possible and decisions have to be made on the basis of statistics and probabilities, the statistical approach to coastal resilience would require stakeholders to make decisions on the basis of probabilities instead of predictions. The science input for informed decisions on adaptation would consist of general probabilities of decadal to century scale sea level changes derived from paleo records, including the probabilities for large and rapid rises. Similar to other problems where the appearance of a hazard is associated with a high risk (like a fire in a house), this approach would also require a monitoring and warning system (a "smoke detector") capable of detecting any onset of a rapid sea level rise.

    Technology assessments of fourteen science instruments were conducted within NASA using the NASA Technology Readiness Level (TRL) Metric. The instruments were part of three NASA Earth Science Decadal Survey missions in pre-formulation. The Earth Systematic Missions Program (ESMP) Systems Engineering Working Group (SEWG), composed of members of three NASA Centers, provided a newly modified electronic workbook to be completed, with instructions. Each instrument development team performed an internal assessment of its technology status, prepared an overview of its instrument, and completed the workbook with the results of its assessment. A team from the ESMP SEWG met with each instrument team and provided feedback. The instrument teams then reported through the Program Scientist for their respective missions to NASA's Earth Science Division (ESD) on technology readiness, taking the SEWG input into account. The instruments were found to have a range of TRL from 4 to 7. Lessons Learned are presented; however, due to the competition-sensitive nature of the assessments, the results for specific missions are not presented. The assessments were generally successful, and produced useful results for the agency. The SEWG team identified a number of potential improvements to the process. Particular focus was on ensuring traceability to guiding NASA documents, including the NASA Systems Engineering Handbook. The TRL Workbook has been substantially modified, and the revised workbook is described.

    2003-12-01

    For the last two years we have conducted a workshop mostly supported by a NASA IDEAS grant on providing professional development for teachers teaching Astronomy/Space Science at high school and middle school level. In some cases this effort has also supported efforts at schools in creating new courses in Space Science. The effort has included a one week summer workshop with as many as six follow up one-day meetings in the school year. The summer workshops have included presentations by experts in current space science research themes and also tours of professional and amateur observatories in and around Wisconsin. The format also allows for some time for teachers to share ideas, curricula among themselves and to present and share "best practices". As in many other instances, the different needs of individual schools, students and teachers prevents a single approach to content and course implementation in schools. Therefore our efforts have focused in serving the needs of individual teachers as much as feasible with limited resources. We gratefully acknowledge the support received from NASA/IDEAS program as well as the Wisconsin Idea program funded by the University of Wisconsin-Madison.

  11. Contribution of science to farm-level aquatic animal health management.

    The contribution of science to farm level disease management is a story of two worlds. The development of effective vaccines has allowed for the control of important salmonid diseases such as furunculosis, yersiniosis and vibriosis and has significantly reduced farmers' reliance on antibiotics. Control of diseases for which cost-effective vaccines have yet to be developed has been achieved through the development of increasingly targeted antibiotics and chemotherapeutants. Increasingly, accurate and rapid diagnostic and water quality tests have allowed farmers to improve farm-level aquatic animal health management. In developed countries, these achievements have been possible thanks to the strong link between science and farm management. This link has been assisted by the presence of strong farmer organizations capable of coordinating research projects and hosting meetings at which scientific information is discussed and disseminated. Although Asia is responsible for the production of about 90% of aquaculture products, it presents a rather different picture from the above. Science has indeed made significant progress in health management but the links with farm management are still weak. Management practices capable of preventing important health problems in shrimp and fish farming are still poorly adopted by farmers. This is largely due to constraints in the dissemination of information to the large number of producers involved, the limited resources of both producers and their countries and the lack of effective farmer organizations capable of liaising with the scientific world. Recently, the Asian region has witnessed some successful examples of aquatic animal health management through the adoption of simple Better Management Practices. Efforts so far have been largely focused on shrimp farming, although activities have been initiated to adopt a similar approach to other commodities. The need for both observational and experimental epidemiological studies to identify simple and affordable farm practices for the control of aquatic animal diseases is highlighted. PMID:18306517

    Technological pedagogical content knowledge-practical (TPACK-P) refers to a unified body of knowledge that teachers develop from and for actual teaching practices with information communication technologies (ICT). This study attempted to unveil the longitudinal and multidimensional development of knowledge that teachers possess by interviewing 40 teachers with various backgrounds in subject content, years of teaching experience, and related award-winning records. An automated cluster analysis was used on the codes given to teachers' responses based on their proficiency levels in different knowledge areas. Three different types of teachers with distinctive features were identified: technology-infusive (TI), technology transitional (TR), and planning and design (PD). TI teachers were more student-centered as compared to TR teachers who were more teacher-centered when asked about possible technology uses. PD teachers were fluent in planning and designing but lacked the balanced development demonstrated by the TI and TR teachers. These science teachers' TPACK were found stayed at the level of "simple adoption." These findings suggest that teachers' TPACK-P needs to be developed with an accumulation of contextualized and dynamic experiences during ICT implementation in actual teaching. Explicit demonstrations regarding how ICTs can be used meaningfully to assist science instruction would be needed in teacher education.

  13. Measuring Student Improvement in Lower- and Upper-Level University Climate Science Courses

    What do university students know about climate? What do they learn in a climate course? On the second-to-last day of a course about global climate change, only 48% of our upper-level science students correctly answered a multiple-choice question about the greenhouse effect. The good news: improvement. Only 16% had answered correctly on the first day of class. The bad news: the learning opportunities we've provided appear to have missed more than half the class on a fundamental climate concept. To evaluate the effectiveness of instruction on student learning about climate, we have developed a prototype assessment tool, designed to be deployed as a low-stakes pre-post test. The items included were validated through student interviews to ensure that students interpret the wording and answer choices in the way we intend. This type of validated assessment, administered both at the beginning and end of term, with matched individuals, provides insight regarding the baseline knowledge with which our students enter a course, and the impact of that course on their learning. We administered test items to students in (1) an upper-level climate course for science majors and (2) a lower-level climate course open to all students. Some items were given to both groups, others to only one of the groups. Both courses use evidence-based pedagogy with active student engagement (clickers, small group activities, regular pre-class preparation). Our results with upper-level students show strong gains in student thinking (>70% of students who missed a question on the pre-test answered correctly on the post-test) about stock-and-flow (box model) problems, annual cycles in the Keeling curve, ice-albedo feedbacks, and isotopic fractionation. On different questions, lower-level students showed strong gains regarding albedo and blackbody emission spectra. Both groups show similar baseline knowledge and lower-than-expected gains on greenhouse effect fundamentals, and zero gain regarding the relative importance of different greenhouse gases. A larger percentage of upper-level students (compared to lower-level students) arrive with correct knowledge comparing different greenhouse gases, and explanations of annual cycles in the Keeling curve, but both groups show similar gains with instruction. Instructors can use feedback from these pre-post assessment results to iteratively modify and test the learning opportunities they provide. We aim to continue development and further validation of this tool such that it can be used in many university-level climate courses.

    This study examined the level of instructional use of Internet among science teachers involved with an in-service professional development project. An instrument on Level of Use of innovation was modified for the study. A criterion sample of teachers to be interviewed via telephone was randomly selected from a pool of 347 K-12 teachers. Somers' d and contingency coefficients were determined to see whether any relationship exists between a teacher's Level of Use and the following categories: (a) amount of experience with the Internet; (b) availability of resources support and access to the Internet in classroom and at home; (c) number of teacher and student users at school, (d) gender; and (e) type of school. Results of step-wise multiple regression indicate that classroom access, instructional experience of using Internet with students, availability of resource support and number of teacher users at school are the best predictors of teacher's Level of Use. Chi square test for comparisons between groups of completers and noncompleters of On-Line West Virginia K-12 RuralNet courses also revealed that a lack of classroom access to Internet and lack of resource/technical support at school contributed significantly to lower level of use among noncompleters.

  17. Project-Based Learning as a Vehicle for Teaching Science at the University Level

    NASA Astrophysics Data System (ADS)

    Courtney, A. R.; Wade, P.

    2012-12-01

    In a typical science course learning is teacher directed. Students are presented with knowledge and concepts via textbooks and lecture and then given the opportunity to apply them. Project-based learning (PBL) creates a context and reason to learn information and concepts. In PBL, learning is student directed and teacher facilitated. Students take ownership of their learning by finding, evaluating and synthesizing information from a variety of resources and via interaction between each other. In PBL, the project is central rather than peripheral to the curriculum. It is not just an activity that provides examples, additional practice or applications of the course content, but rather, the vehicle through which major concepts are discovered. The PBL process requires students to do revision and reflection encouraging them to think about what and how they are learning. PBL projects also allow students to develop important life-work skills such as collaboration, communication and critical thinking within the discipline. We have employed PBL in both Liberal Arts courses for non-science majors and upper division courses for science students. Three examples will be discussed. The first will be the production of video documentaries in a non-science major course; the second, a student generated electronic textbook in a 300-level energy course for science students; and lastly, a student designed analysis project in a chemistry major capstone laboratory course. The product in each of these examples was used to deliver knowledge to others in the class as well as members of the public providing motivation for students to do high-quality work. In our examples, student documentaries are publicly screened as part of a university-wide Academic Excellence Showcase; the student generated electronic textbook is available for public use on the internet; and the results of the student designed analysis were communicated to the real-world clients via letters and reports. We will discuss various technology tools employed in these projects such as the internet, wikis for collaborative writing, bookmarking management tools for sharing literature resources, photo sharing sites, and electronic literature searching tools. Also described will be assessment methods to gauge how the projects affected student learning.

    Introduction: Many studies have investigated the relationship between motivation and educational outcomes. The present study was conducted to determine whether the students’ motivation in Shiraz University of Medical Sciences (SUMS) decreases during educational years. Methods: 770 students in SUMS were selected by multi-stage stratified random sampling from each field and entrance year. The first questionnaire contained 57 questions on the effect of economic, social, educational, geographical and personality factors on the students’ motivation. The second one was based on 50 incomplete sentences. The validity and reliability of these questionnaires were approved by the experts and Cronbach's Alpha coefficients (85% and 90%, respectively). In this cross-sectional study, ANOVA, t-test and Chi-square tests were applied for data analysis at the 0.05 significance level. Results: Six factors with the most effect on academic motivation were "family attitudes", "getting good jobs in future", "respect for themselves", " the ability to learn", "believing their role in victory and defeat" and "the tendency toward optimism about themselves". In addition, comparing professional doctorate and basic sciences’ results revealed no significant relationship between academic motivation and educational years (F=0.819, p=0.397). But comparing field by field showed that Dentistry and Hospital Management and Medical Information (HMMI) had a significant decrease in motivation score by increase in educational years (F=3.991, p=0.015). Conclusion: Achievement motivation level in SUMS students was higher than average and did not decrease during educational years. Also, the results showed that personal, social and educational related factors affected motivation level more than economic and environmental factors. PMID:25587552

  20. An investigation of gender and grade-level differences in middle school students' attitudes about science, in science process skills ability, and in parental expectations of their children's science performance

    White, Terri Renee'

    The primary purpose of the study was to examine different variables (i.e. science process skill ability, science attitudes, and parents' levels of expectation for their children in science, which may impinge on science education differently for males and females in grades five, seven, and nine. The research question addressed by the study was: What are the differences between science process skill ability, science attitudes, and parents' levels of expectation in science on the academic success of fifth, seventh, and ninth graders in science and do effects differ according to gender and grade level? The subjects included fifth, seven, and ninth grade students ( n = 543) and their parents (n = 474) from six rural, public elementary schools and two rural, public middle schools in Southern Mississippi. A two-way (grade x gender) multivariate analysis of variance (MANOVA) was used to determine the differences in science process skill abilities of females and males in grade five, seven, and nine. An additional separate two-way multivariate analysis of variance (grade x gender) was also used to determine the differences in science attitudes of males and females in grade five, seven, and nine. A separate analysis of variance (PPSEX [parent's gender]) with the effects being parents' gender was used to determine differences in parents' levels of expectation for their childrens' performance in science. An additional separate analysis of variance (SSEX [student's gender]) with the effects being the gender of the student was also used to determine differences in parents' levels of expectation for their childrens' performance in science. Results of the analyses indicated significant main effects for grade level (p < .001) and gender (p < .001) on the TIPS II. There was no significant grade by gender interaction on the TIPS II. Results for the TOSRA also indicated a significant main effect for grade (p < .001) and the interaction of grade by sex ( p < .001). On variable ATT 5 (enjoyment of science lessons), males' attitudes toward science decreased across the grade levels; whereas, females decreased from grade five to seven, but showed a significant increase from grade seven to nine. Results from the analysis of variance with the parent's gender as the main effect showed no significant difference. The analysis of variance with student's gender as the main effect showed no significant difference.

    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.

  9. Using High Level Literacy Techniques to Teach Astronomy to Non-Science Majors

    NASA Astrophysics Data System (ADS)

    Garland, C. A.; Ratay, D. L.

    2005-12-01

    We present a discussion of an introductory-level college astronomy class which significantly relied on reading and writing assignments to deliver basic content knowledge and provide a basis for deeper analysis of the material. As opposed to the traditional problem-set method of homework, students were required to read popular articles from magazines and newspapers related to the content presented in class and then prepare responses. Responses ranged from methodological analysis to using the readings to create original science journalism. Other forms of assessment indicated that students benefitted from this type of course design. We propose that given the background of students in this type of course, the course design is better suited to engage students in the material and provides a better assessment of student achievement.

    The Archival Legacy Investigation of Circumstellar Environments (ALICE) project (HST/AR program 12652; PI Soummer) is currently conducting a comprehensive and consistent reprocessing of HST-NICMOS coronagraphic survey data to search for point sources and disks using advanced PSF subtraction. The Karhunen-Loeve Image Projection (KLIP) algorithm based on principal component analysis was developed for this project. We present the main concept for the pipeline, reduction strategy, and PSF subtraction implementation and performance. The ALICE pipeline was designed to process automatically approximately 400 targets in the NICMOS coronagraphic archive, and to deliver High-Level Science Products (HLSPs) back to the MAST archive at STScI. The HLSPs are defined in collaboration with other similar projects to define a standard format for high-contrast imaging. We present and discuss the ALICE point source candidates detected in the NICMOS archive together with a statistical analysis of the population of background objects.

    The impact of global climate change is far-reaching, both for humanity and for the environment. It is essential that our students be provided a strong scientific background for the role of natural and human caused climate change so that they are better prepared to become involved in the discussion. Here the author reveals a successful model designed for use with a diverse student body at the community college level. Teaching strategies beyond the traditional lecture and exam style include: web-based resources such as static websites along with dynamic blogging tools, post-lecture cooperative learning review sessions, weekly current event research projects, use of rubrics to assist students in their own project evaluation before submission, and a research paper utilizing the Skeptical Science website to examine the validity of the most common climate change myths.

  15. Attitudes and beliefs, about inquiry science, of middle level and secondary science teachers in northwest Arkansas and northwest Oklahoma

    NASA Astrophysics Data System (ADS)

    Dockers, Jean E.

    A This study attempted to close gaps in the literature with regards to implementation of inquiry practices in secondary science classrooms. In addition, the areas and ways in which practice ties to beliefs and experiences in the area of inquiry were examined. This study introduces an instrument that could be used to assess teachers' attitudes and beliefs about inquiry teaching practices and potential barriers to teaching science using an inquiry approach. Because the efficacy of reform efforts rests largely with teachers, their voices need to be included in the design and implementation of inquiry---based curriculum. This study helps to clarify the need for future research to examine inquiry as a pedagogical approach. If we desire pre-service teachers to teach using an inquiry approach when they have their own classrooms, they must know how to plan, implement, and assess inquiry science lessons, not just have experienced "inquiry lessons" as a student. One unique finding in this study was in the area of licensure and teaching style. Other studies found that in general traditionally licensed teachers felt better prepared to teach. This study found that participants who were alternatively certified incorporated characteristics of inquiry less often than those with traditional certification. This indicates that more research is needed in the area of certification and the affect it may have on quality of instruction for specific content areas like science.

    Throughout Earth history a small number of global catastrophic events leading to biotic crises have caused mass extinctions. Here, using a technique that combines taxonomic and numerical data, we consider the effects of the Cenomanian-Turonian and Cretaceous-Tertiary mass extinctions on the terrestrial spider fauna in the light of new fossil data. We provide the first evidence that spiders suffered no decline at the family level during these mass extinction events. On the contrary, we show that they increased in relative numbers through the Cretaceous and beyond the Cretaceous-Tertiary extinction event. PMID:14686534

  1. An Investigation of Factors Affecting Elementary Female Student Teachers' Choice of Science as a Major at College Level in Zimbabwe

    NASA Astrophysics Data System (ADS)

    Mlenga, Francis

    This article focuses on factors affecting elementary female student teachers' choice of science as a major at college level in Zimbabwe. In Sub-Saharan Africa, there has been an unprecedented expansion in education in the last 2 decades. This reflects the broad recognition that education contributes to national development. This expansion has not been matched with equal access and opportunity to education. The education of females still lags behind that of males in most developing countries, and in Sub-Saharan Africa in particular (Hyde, 1989). Fewer girls than boys study science at both secondary and college levels. The study took place in Zimbabwe at Mkoba Teachers' College. Two groups of elementary female student teachers participated in the study, namely science majors and nonscience majors. Ten science majors and nine nonscience majors took part in individual interviews. For focus group interviews, there were three groups of six each from science and nonscience majors. The study was conducted between May 2004 and July 2004. Out-of-school experiences, culture, and attitudes toward science emerged as factors affecting female student teachers' choice of science as a major. A number of implications have been discussed as well as suggestions for further research. Limitations of the study have been analyzed as well.

  2. Systems Science and Obesity Policy: A Novel Framework for Analyzing and Rethinking Population-Level Planning

    Matteson, Carrie L.; Finegood, Diane T.

    2014-01-01

    Objectives. We demonstrate the use of a systems-based framework to assess solutions to complex health problems such as obesity. Methods. We coded 12 documents published between 2004 and 2013 aimed at influencing obesity planning for complex systems design (9 reports from US and Canadian governmental or health authorities, 1 Cochrane review, and 2 Institute of Medicine reports). We sorted data using the intervention-level framework (ILF), a novel solutions-oriented approach to complex problems. An in-depth comparison of 3 documents provides further insight into complexity and systems design in obesity policy. Results. The majority of strategies focused mainly on changing the determinants of energy imbalance (food intake and physical activity). ILF analysis brings to the surface actions aimed at higher levels of system function and points to a need for more innovative policy design. Conclusions. Although many policymakers acknowledge obesity as a complex problem, many strategies stem from the paradigm of individual choice and are limited in scope. The ILF provides a template to encourage natural systems thinking and more strategic policy design grounded in complexity science. PMID:24832406

    The Mikulski Archive for Space Telescopes (MAST) is a NASA-funded archive for a wide range of astronomical missions, primarily supporting space-based UV and optical telescopes. What is less well-known is that MAST provides much more than just a final resting place for primary data products and documentation from these missions. The MAST Discovery Portal is our new search interface that integrates all the missions that MAST supports into a single interface, allowing users to discover (and retrieve) data from other missions that overlap with your targets of interest. In addition to searching MAST, the Portal allows users to search the Virtual Observatory, granting access to data from thousands of collections registered with the VO, including large missions spanning the electromagnetic spectrum (e.g., Chandra, SDSS, Spitzer, 2MASS, WISE). The Portal features table import/export, coordinate-based cross-matching, dynamic chart plotting, and the AstroView sky viewer with footprint overlays. We highlight some of these capabilities with science-driven examples. MAST also accepts High Level Science Products (HLSPs) from the community. These HLSPs are user-generated data products that can be related to a MAST-supported mission. MAST provides a permanent archive for these data with linked references, and integrates it within MAST infrastructure and services. We highlight some of the most recent HLSPs MAST has released, including the HST Frontier Fields, GALEX All-Sky Diffuse Radiation Mapping, a survey of the intergalactic medium with HST-COS, and one of the most complete line lists ever derived for a white dwarf using FUSE AND HST-STIS. These HLSPs generate substantial interest from the community, and are an excellent way to increase visibility and ensure the longevity of your data.

  8. Effect of using repurposed science-rich feature films with varying levels of student activity in middle grades science instruction

    NASA Astrophysics Data System (ADS)

    Cavanaugh, Terence William

    This study provided an initial investigation into the use of repurposed content-rich entertainment videos (versus traditional educational videos) presented in either an active or passive educational setting. Eight classes of seventh grade general science students (n = 361) were randomly assigned to one of four video treatment groups: (1) repurposed content-rich entertainment video in a passive setting, (2) repurposed content-rich entertainment video in an active setting, (3) traditional educational video in a passive setting, and (4) traditional educational video in an active setting. The subject matter of the videos focused on basic chemistry, scientific method, and the nature of life. The repurposed content-rich entertainment groups watched a StarTrek the Next Generation episode, and the traditional educational video groups watched videos from NASA and the Understanding Science Corporation. Students completed a knowledge-based pretest and an initial attitude survey prior to the treatment. During the treatment, all participants watched the videos, discussed the science content, and answered directed questions. Active setting groups discussed and answered questions during the video, while the passive setting groups discussed and answered questions after the video. The treatment period lasted approximately 135 minutes. Immediately following treatment, participants received a knowledge-based posttest and an attitude survey. Three weeks after treatment, retention tests and follow-up surveys were administered. Test and survey data were analyzed using single factor and repeated measures ANOVA followed by post hoc tests. Significant gains (p < 0.05) in test scores were found for repurposed content-rich entertainment video over traditional educational video groups. No significant differences were found in test scores between the active and passive setting groups. When the variables were combined, additional effects were noted. Specifically, significant differences were noted over time with the passive educational group performing lower than the passive repurposed group on mean test scores. No significant differences were noted for attitude change toward science in comparing repurposed content-rich entertainment video group and traditional educational video group. A significant difference was found in how the subjects' attitudes changed for the active (increasing then decreasing) versus the passive watching groups (decreasing then increasing). The results of the study indicate that the use of content-rich entertainment video may provide an effective alternative for science education.

  11. Perceptions of teaching and learning automata theory in a college-level computer science course

    NASA Astrophysics Data System (ADS)

    Weidmann, Phoebe Kay

    This dissertation identifies and describes student and instructor perceptions that contribute to effective teaching and learning of Automata Theory in a competitive college-level Computer Science program. Effective teaching is the ability to create an appropriate learning environment in order to provide effective learning. We define effective learning as the ability of a student to meet instructor set learning objectives, demonstrating this by passing the course, while reporting a good learning experience. We conducted our investigation through a detailed qualitative case study of two sections (118 students) of Automata Theory (CS 341) at The University of Texas at Austin taught by Dr. Lily Quilt. Because Automata Theory has a fixed curriculum in the sense that many curricula and textbooks agree on what Automata Theory contains, differences being depth and amount of material to cover in a single course, a case study would allow for generalizable findings. Automata Theory is especially problematic in a Computer Science curriculum since students are not experienced in abstract thinking before taking this course, fail to understand the relevance of the theory, and prefer classes with more concrete activities such as programming. This creates a special challenge for any instructor of Automata Theory as motivation becomes critical for student learning. Through the use of student surveys, instructor interviews, classroom observation, material and course grade analysis we sought to understand what students perceived, what instructors expected of students, and how those perceptions played out in the classroom in terms of structure and instruction. Our goal was to create suggestions that would lead to a better designed course and thus a higher student success rate in Automata Theory. We created a unique theoretical basis, pedagogical positivism, on which to study college-level courses. Pedagogical positivism states that through examining instructor and student perceptions of teaching and learning, improvements to a course are possible. These improvements can eventually develop a "best practice" instructional environment. This view is not possible under a strictly constructivist learning theory as there is no way to teach a group of individuals in a "best" way. Using this theoretical basis, we examined the gathered data from CS 341. (Abstract shortened by UMI.)

  12. Tertiary carbonate reservoirs in Indonesia

    SciTech Connect

    Nayoan, G.A.S.; Arpandi; Siregar, M.

    1981-01-01

    Hydrocarbon production from Tertiary carbonate reservoirs accounted for ca. 10% of daily Indonesian production at the beginning of 1978. Environmentally, the reservoirs appear as parts of reef complexes and high-energy carbonate deposits within basinal areas situated mainly in the back arc of the archipelago. Good porosities of the reservoirs are represented by vugular/moldic and intergranular porosity types. The reservoirs are capable of producing prolific amounts of hydrocarbons: production tests in Salawati-Irian Jaya reaches maximum values of 32,000 bpd, and in Arun-North Sumatra tests recorded 200 MMCF gas/day. Significant hydrocarbon accumulations are related to good reservoir rocks in carbonates deposited as patch reefs, pinnacle reefs, and platform complexes. Exploration efforts expand continuously within carbonate formations which are extensive horizontally as well as vertically in the Tertiary stratigraphic column.

  13. Effects of multisensory resources on the achievement and science attitudes of seventh-grade suburban students taught science concepts on and above grade level

    NASA Astrophysics Data System (ADS)

    Roberts, Patrice Helen

    This research was designed to determine the relationships among students' achievement scores on grade-level science content, on science content that was three years above-grade level, on attitudes toward instructional approaches, and learning-styles perceptual preferences when instructional approaches were multisensory versus traditional. The dependent variables for this investigation were scores on achievement posttests and scores on the attitude survey. The independent variables were the instructional strategy and students' perceptual preferences. The sample consisted of 74 educationally oriented seventh-grade students. The Learning Styles Inventory (LSI) (Dunn, Dunn, & Price, 1990) was administered to determine perceptual preferences. The control group was taught seventh-grade and tenth-grade science units using a traditional approach and the experimental group was instructed on the same units using multisensory instructional resources. The Semantic Differential Scale (SDS) (Pizzo, 1981) was administered to reveal attitudinal differences. The traditional unit included oral reading from the textbook, completing outlines, labeling diagrams, and correcting the outlines and diagrams as a class. The multisensory unit included five instructional stations established in different sections of the classroom to allow students to learn by: (a) manipulating Flip Chutes, (b) using Electroboards, (c) assembling Task Cards, (d) playing a kinesthetic Floor Game, and (e) reading an individual Programmed Learning Sequence. Audio tapes and scripts were provided at each location. Students circulated in groups of four from station to station. The data subjected to statistical analyses supported the use of a multisensory, rather than a traditional approach, for teaching science content that is above-grade level. T-tests revealed a positive and significant impact on achievement scores (p < 0.0007). No significance was detected on grade-level achievement nor on the perceptual-preference effect. Furthermore, the students indicated significantly more positive attitudes when instructed with a multisensory approach on either grade-level or above-grade level science content (p < 0.0001). The findings supported using a multisensory approach when teaching science concepts that are new to and difficult for students (Martini, 1986).

  14. Evolution of Tertiary Mammals of North America

    NASA Astrophysics Data System (ADS)

    Janis, Christine M.; Scott, Kathleen M.; Jacobs, Louis L.

    2005-03-01

    This book is a unique compendium and synthesis of the cumulative knowledge of more than 100 years of discovery and study of North American tertiary mammals. The potentially most valuable contribution of this book is the detailed information of the distribution in time and space of each species at fossil localities, recorded in a uniform scheme, so that each chapter provides the same level of information. Thirty six chapters are devoted to a particular family or order, written by leading North American authorities, including discussion of anatomical features, systematics, and paleobiology. Three introductory chapters summarize information on the geological time scale, Tertiary vegetation, and Pleistocene events, and four summary chapters integrate systematic and biogeographic information for higher taxa. This book will serve as a unique data base for continuing studies in faunal diversification and change, and for questions such as how changing biogeography and climates influenced the evolution of mammalian communities. It will be an invaluable addition to the libraries of paleontologists and zoologists.

  4. Classroom management at the university level: lessons from a former high school earth science teacher

    Lazar, C.

    2009-12-01

    Just a few days before my career as a fledgling science teacher began in a large public high school in New York City, a mentor suggested I might get some ideas about how to run a classroom from a book called The First Days Of School by Harry Wong. Although the book seemed to concentrate more on elementary students, I found that many of the principles in the book worked well for high school students. Even as I have begun to teach at the university level, many of Wong’s themes have persisted in my teaching style. Wong’s central thesis is that for learning to occur, a teacher must create the proper environment. In education jargon, a good climate for learning is generated via classroom management, an array of methods used by elementary and secondary school teachers to provide structure and routine to a class period via a seamless flow of complementary activities. Many college professors would likely consider classroom management to be chiefly a set of rules to maintain discipline and order among an otherwise unruly herd of schoolchildren, and therefore not a useful concept for mature university students. However, classroom management is much deeper than mere rules for behavior; it is an approach to instructional design that considers the classroom experience holistically. A typical professorial management style is to lecture for an hour or so and ask students to demonstrate learning via examinations several times in a semester. In contrast, a good high school teacher will manage a class from bell-to-bell to create a natural order and flow to a given lesson. In this presentation, I will argue for an approach to college lesson design similar to the classroom management style commonly employed by high school and elementary school teachers. I will suggest some simple, practical techniques learned during my high school experience that work just as well in college: warm-up and practice problems, time management, group activities, bulletin boards, learning environment, and standard procedures. Central to all of these suggestions is the basic concept of planning activities for students beyond passive absorption of lecture material and fitting them smoothly within the typical time constraints of a class period. Well-managed students learn better. I close with the observation that the most basic desires of students are independent of age; learners of all ages and levels prefer well-designed classroom experiences. In this context, books and resources intended for the professional development of secondary--and even elementary—teachers suddenly contain a wealth of techniques that, with some modification, might be useful at the university level.

  5. Climate Change and Sea Level Rise: A Challenge to Science and Society

    NASA Astrophysics Data System (ADS)

    Plag, H.

    2009-12-01

    Society is challenged by the risk of an anticipated rise of coastal Local Sea Level (LSL) as a consequence of future global warming. Many low-lying and often subsiding and densely populated coastal areas are under risk of increased inundation, with potentially devastating consequences for the global economy, society, and environment. Faced with a trade-off between imposing the very high costs of coastal protection and adaptation upon today's national economies and leaving the costs of potential major disasters to future generations, governments and decision makers are in need of scientific support for the development of mitigation and adaptation strategies for the coastal zone. Low-frequency to secular changes in LSL are the result of many interacting Earth system processes. The complexity of the Earth system makes it difficult to predict Global Sea Level (GSL) rise and, even more so, LSL changes over the next 100 to 200 years. Humans have re-engineered the planet and changed major features of the Earth surface and the atmosphere, thus ruling out extrapolation of past and current changes into the future as a reasonable approach. The risk of rapid changes in ocean circulation and ice sheet mass balance introduces the possibility of unexpected changes. Therefore, science is challenged with understanding and constraining the full range of plausible future LSL trajectories and with providing useful support for informed decisions. In the face of largely unpredictable future sea level changes, monitoring of the relevant processes and development of a forecasting service on realistic time scales is crucial as decision support. Forecasting and "early warning" for LSL rise would have to aim at decadal time scales, giving coastal managers sufficient time to react if the onset of rapid changes would require an immediate response. The social, environmental, and economic risks associated with potentially large and rapid LSL changes are enormous. Therefore, in the light of the current uncertainties and the unpredictable nature of some of the forcing processes for LSL changes, the focus of scientific decision support may have to shift from projections of LSL trajectories on century time scales to the development of models and monitoring systems for a forecasting service on decadal time scales. The requirements for such a LSL forecasting service and the current obstacles will be discussed.

    This article describes a study of links between school environment and science classroom environment. Instruments to assess seven dimensions of school environment (viz., Empowerment, Student Support, Affiliation, Professional Interest, Mission Consensus, Resource Adequacy and Work Pressure) and seven dimensions of classroom environment (viz., Student Affiliation, Interactions, Cooperation, Task Orientation, Order & Organisation, Individualisati n and Teacher Control) in secondary school science classrooms were developed and validated. The study involved a sample of 1,318 students in 64 year 9 and year 12 science classes and 128 teachers of science in Australian secondary schools. Using the class mean as the unit of analysis for student data, associations between school and classroom environment were investigated using simple, multiple and canonical correlational analyses. In general, results indicated weak relationships between school and classroom environments and they reinforced the view that characteristics of the school environment are not transmitted automatically into science classrooms.

    Yates, Janet; Smith, Jennifer; James, David; Ferguson, Eamonn

    2009-01-01

    Background It has been suggested that studying non-science subjects at A-level should be compulsory for medical students. Our admissions criteria specify only Biology, Chemistry and one or more additional subjects. This study aimed to determine whether studying a non-science subject for A-level is an independent predictor of achievement on the undergraduate medical course. Methods The subjects of this retrospective cohort study were 164 students from one entry-year group (October 2000), who progressed normally on the 5-year undergraduate medical course at Nottingham. 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. Results 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 < 0.001, and pre-clinical Themes C&D (skills) predicted Clinical Skills, p = < 0.01). Conclusion This study of one year group at Nottingham Medical School provided no evidence that the admissions policy on A-level requirements should specify the choice of third or fourth subject.

    1988-01-01

    The asteroid hypothesis has stimulated numerous studies of the paleontological record at Cretaceous/Tertiary time as well as of geological indicators of environmental crisis preserved in the rock record. Both extinctions and geological anomalies often occur at times that do not appear to be synchronous or instantaneous. The record includes paleontological indicators of dinosaurs, terrestrial flora, marine planktonic organisms, and shallow water marine macrofauna and geological phenomena include occurrences of iridium and other platinum metals, trace elements, clay mineralogy, shocked minerals, soot, microspherules, and isotopes of osmium, strontium and carbon. These findings are reviewed in the context of the alternate hypotheses of an exogenic cause, involving either a single asteroid impact or multiple commentary impacts, and an endogenic cause, involving intense global volcanism and major sea level regression.

  17. Developing partnerships for implementing continental-scale citizen science programs at the local-level

    2012-12-01

    Project BudBurst is a citizen science project focused on monitoring plant phenology that resides at the National Ecological Observatory Network (NEON, Inc). A central question for Project BudBurst and other national outreach programs is: what are the most effective means of engaging and connecting with diverse communities throughout the country? How can continental scale programs like NEON's Project BudBurst engage audiences in such a way as to be relevant at both the local and continental scales? Staff with Project BudBurst pursued partnerships with several continental scale organizations: the National Wildlife Refuge System, the National Park Service, and botanic gardens to address these questions. The distributed nature of wildlife refuges, national parks, and botanic gardens around the country provided the opportunity to connect with participants locally while working with leadership at multiple scales. Project BudBurst staff talked with hundreds of staff and volunteers prior to setting a goal of obtaining and developing resources for several Refuge Partners, a pilot National Park partner, and an existing botanic garden partner during 2011. We were especially interested in learning best practices for future partnerships. The partnership efforts resulted in resource development for 12 Refuge partners, a pilot National Park partner, and 2 botanic garden partners. Early on, the importance of working with national level leaders to develop ownership of the partner program and input about resource needs became apparent. Once a framework for the partnership program was laid out, it became critical to work closely with staff and volunteers on the ground to ensure needs were met. In 2012 we began to develop an online assessment to allow our current and potential partners to provide feedback about whether or not the partnership program was meeting their needs and how the program could be improved. As the year progressed, the timeline for resource development became more of a suggestion than a set schedule. Maintaining flexibility was critical to the success of the partnerships. Unanticipated fieldwork, new priorities within organizations, and differing levels of involvement from partner staff, advisory boards, or Friends groups, led to varying resource development timelines. The distributed nature of and the willingness of partner staff and volunteers to implement Project BudBurst at their facilities have broadened the participation of the public in this program more than could have been accomplished alone. The new partners benefit from the free and customized education and outreach materials provided by Project BudBurst, while Project BudBurst benefits from the local knowledge and contacts with the public from the partner organizations.

    The objectives of this quantitative survey research were (1) to establish the level of scientific reasoning (SR) skills among science, mathematics and engineering (SME) undergraduates in Malaysian Institute of Higher Learning (IHL); (b) to identify the types of instructional methods in teaching SME at universities; and (c) to map instructional methods employed to the level of SR skills among the undergraduates. There were six universities according to zone involved in this study using the stratification random sampling technique. For each university, the faculties that involved were faculties which have degree students in science, mathematics and engineering programme. A total of 975 students were participated in this study. There were two instruments used in this study namely, the Lawson Scientific Reasoning Skills Test and the Lecturers' Teaching Style Survey. The descriptive statistics and the inferential statistics such as mean, t-test and Pearson correlation were used to analyze the data. Findings of the study showed that most students had concrete level of scientific reasoning skills where the overall mean was 3.23. The expert and delegator were dominant lecturers' teaching styles according to students' perception. In addition, there was no correlation between lecturers' teaching style and the level of scientific reasoning skills. Thus, this study cannot map the dominant lecturers' teaching style to the level of scientific reasoning skills of Science, Mathematics and Engineering undergraduates in Malaysian Public Institute of Higher Learning. Nevertheless, this study gave some indications that the expert and delegator teaching styles were not contributed to the development of students' scientific reasoning skills. This study can be used as a baseline for Science, Mathematics and Engineering undergraduates' level of scientific reasoning skills in Malaysian Public Institute of Higher Learning. Overall, this study also opens an endless source of other researchers to investigate more areas on scientific reasoning skills so that the potential instructional model can be developed to enhance students' level of scientific reasoning skills in Malaysian Public Institute of Higher Learning.

    2005-12-01

    I will discuss about the situation of the level of interest in Science & Technology (S&T) among Japanese. The interest was at its peak in 1976 over past 30 years. It generally fell until the most recent survey in 2004. Of particular interest is a breakdown of the respondents by age. In 1976, people in their 20s reported the highest level of interest in S&T. Over time, that group's interest has waned. Now it is the age group with the lowest level of interest in S&T. I'm going to suggest how to improve people's interest in S&T. The way is to promote Science Communication.

  3. Endosymbiotic Gene Transfer in Tertiary Plastid-Containing Dinoflagellates

    2014-01-01

    Plastid establishment involves the transfer of endosymbiotic genes to the host nucleus, a process known as endosymbiotic gene transfer (EGT). Large amounts of EGT have been shown in several photosynthetic lineages but also in present-day plastid-lacking organisms, supporting the notion that endosymbiotic genes leave a substantial genetic footprint in the host nucleus. Yet the extent of this genetic relocation remains debated, largely because the long period that has passed since most plastids originated has erased many of the clues to how this process unfolded. Among the dinoflagellates, however, the ancestral peridinin-containing plastid has been replaced by tertiary plastids on several more recent occasions, giving us a less ancient window to examine plastid origins. In this study, we evaluated the endosymbiotic contribution to the host genome in two dinoflagellate lineages with tertiary plastids. We generated the first nuclear transcriptome data sets for the “dinotoms,” which harbor diatom-derived plastids, and analyzed these data in combination with the available transcriptomes for kareniaceans, which harbor haptophyte-derived plastids. We found low level of detectable EGT in both dinoflagellate lineages, with only 9 genes and 90 genes of possible tertiary endosymbiotic origin in dinotoms and kareniaceans, respectively, suggesting that tertiary endosymbioses did not heavily impact the host dinoflagellate genomes.

  4. Context, accuracy, and level of inclusion of nature of science concepts in current high school physics textbooks

    NASA Astrophysics Data System (ADS)

    Alshamrani, Saeed Mohammed

    To improve K-12 students' images of the nature of science (NOS) through science textbooks, two issues must be addressed: (a) the level of NOS that ought to be included in science textbooks and (b) the treatment of this level in those textbooks. Science educators achieved a consensus level of agreement regarding what NOS aspects should be taught for K-12 science learners; however, there is a need for more clarification regarding the actual treatment of NOS in science textbooks. The purpose of this study is to investigate the NOS inclusion in high school physics textbooks. To be specific, this study examines the included NOS aspects, the frequency of NOS inclusion, the contexts exist for NOS inclusion, and the accuracy of NOS inclusion. This study utilized 12 science education studies to develop the Master Aspects of Nature of Science [MA-NOS] which includes 12 NOS aspects that ought to be included in K-12 science curriculum. The analyzed textbooks in this study are seven textbooks identified by The American Institute of Physics as the most widely used high school physics textbooks in the United States in 2005. These textbooks were used in teaching five academic levels: (a) Regular First-Year Physics, (b) Physics for Non-Science Students, (c) Honors Physics, (d) AP-B Physics, and (e) AP-C Physics. The researcher selected exclusively physics textbooks because physics is his main interest. To facilitate the content analysis of the selected textbooks, the study developed The Collection Data Coding Guide which includes six parts describing the MA-NOS aspects and the process of identifying and collecting data. For each NOS aspect, a description and one or more selected ideal indicators were provided to facilitate data collecting and judging the accuracy of NOS inclusion. This coding guide was reviewed for its content validity by two science educators who specialize in NOS. However, two types of reliability were conducted to identify the consistency of selecting NOS units, classifying contexts existing for NOS inclusion, identifying NOS elements, and judging NOS inclusion accuracy. The agreements over time "rate-rerate reliability" were 100%, 96.97%, 79.36%, and 100% respectively. However, the agreements among analysts "inter-rate reliability" were 100%, 92.3%, 66.7%, and 96.2% respectively. This study permitted eliminating, adding, or modifying NOS indicators through textbook analysis. At the end of this study, three indicators were eliminated, one was added, and one was modified. The final version of the coding guide includes 36 indicators representing the meaning of the ML-NOS. The findings of the first research question indicate that all NOS aspects are included in the textbooks except "there is a distinction between observations and inferences." However, the textbooks vary in their inclusion of NOS aspects; each textbook includes between five to 11 different NOS aspects. The results of the second question indicate that the frequencies of NOS inclusion range between 41 to 174 instances in the textbooks. The textbooks seem to include more NOS elements related to "scientific knowledge is tentative," "there is a distinction between scientific laws and theories," "scientific knowledge is empirically based," "the absence of a universal step-wise scientific method," "cooperation and collaboration in development of scientific knowledge," and "the role of experiment in science." The findings of the third research question indicate that 84.5% of the total included NOS elements in the textbooks are included through the main texts. 15.5% of the elements are included through figures, lab activities, boxed-in sections, and glossary sections; however, no elements are included through tables or charts. The results also indicate that more utilization of types of contexts beside the main text associates with more NOS inclusion. The results of the fourth question indicate that 14 NOS elements, with 2.3% of the total elements, are inaccurately included in

    2014-12-01

    The prupose of this paper is to present the "Adaptation Research a Transdisciplinary community and policy centered appoach" (ARTisticc) project. ARTisticc's goal is to apply innovative standardized transdisciplinary art and science integrative approaches to foster robust, socially, culturally and scientifically, community centred adaptation to climate change. The approach used in the project is based on the strong understanding that adaptation is: (a) still "a concept of uncertain form"; (b) a concept dealing with uncertainty; (c) a concept that calls for an analysis that goes beyond the traditional disciplinary organization of science, and; (d) an unconventional process in the realm of science and policy integration. The project is centered on case studies in France, Greenland, Russia, India, Canada, Alaska, and Senegal. In every site we jointly develop artwork while we analyzing how natural science, essentially geosciences can be used in order to better adapt in the future, how society adapt to current changes and how memories of past adaptations frames current and future processes. Artforms are mobilized in order to share scientific results with local communities and policy makers, this in a way that respects cultural specificities while empowering stakeholders, ARTISTICC translates these "real life experiments" into stories and artwork that are meaningful to those affected by climate change. The scientific results and the culturally mediated productions will thereafter be used in order to co-construct, with NGOs and policy makers, policy briefs, i.e. robust and scientifically legitimate policy recommendations regarding coastal adaptation. This co-construction process will be in itself analysed with the goal of increasing arts and science's performative functions in the universe of evidence-based policy making. The project involves scientists from natural sciences, the social sciences and the humanities, as well as artitis from the performing arts (playwriters, film directors) as well as the visual arts (photographs, designers, sculptor) working in France, Senegal, India, Russia, Greenland, Alaska, and Canada

  6. Content, format, gender and grade level differences in elementary students' ability to read science materials as measured by the cloze procedure

    NASA Astrophysics Data System (ADS)

    Williams, Richard L.; Yore, Larry D.

    Present instructional trends in science indicate a need to reexamine a traditional concern in science education: the readability of science textbooks. An area of reading research not well documented is the effect of color, visuals, and page layout on readability of science materials. Using the cloze readability method, the present study explored the relationships between page format, grade level, sex, content, and elementary school students ability to read science material. Significant relationships were found between cloze scores and both grade level and content, and there was a significant interaction effect between grade and sex in favor of older males. No significant relationships could be attributed to page format and sex. In the area of science content, biological materials were most difficult in terms of readability followed by earth science and physical science. Grade level data indicated that grade five materials were more difficult for that level than either grade four or grade six materials were for students at each respective level. In eight of nine cases, the science text materials would be classified at or near the frustration level of readability. The implications for textbook writers and publishers are that science reading materials need to be produced with greater attention to readability and known design principles regarding visual supplements. The implication for teachers is that students need direct instruction in using visual materials to increase their learning from text material. Present visual materials appear to neither help nor hinder the student to gain information from text material.

    The purpose of this study was to assess and evaluate the status of energy education in the State of Alabama. Specifically, the study dealt with personal characteristics of the secondary school science teachers along with school characteristics and whether or not these characteristics related to teaching energy education, topics, methods, and procedures used in existing energy education programs. The sample consisted of 400 randomly selected secondary school science teachers in the State of Alabama; 249 questionnaires were returned. This instrument requested demographic information and information on the status of energy education as taught in the secondary school science classes in the State of Alabama. Nonparametric techniques were employed throughout the analysis procedure. Chi square was the statistical test used. The major findings were: (1) the sex, age, number of years of teaching experience, level of certification, and current enrollment in an advanced degree program were not related to the teaching of energy education; (2) the academic major of the teacher and the subject taught related to the teaching of energy education; (3) junior-high science teachers used more-varied teaching strategies than the senior-high science teachers; (4) the primary method of instruction was by integration into appropriate units; and (5) energy education was taught from one to ninety-nine days. The mean number of days was sixteen.

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

    NASA Astrophysics Data System (ADS)

    Cook, G. W.

    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 (<3%) are Earth science 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 backgroundā€”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 volcanoesā€”a fascinating subject in and of itselfā€”I take the opportunity in the first two weeks to introduce students to basic geology, including tectonics, earth materials, surface processes, and geologic time. In fact, this is a vital segment of the class, as the students need this background for the latter portions of the class. A side benefit is that students are provided with a "mini" education in geology whether they know it or not and take this knowledge with them into other classes, and ultimately, their futures. Student satisfaction is uniformly very high with this class. 100% of students agreed that the course material was intellectually stimulating; 95% of students agreed that they learned a great deal from the course; 100% of students stated that they would recommend the class to other students. Overall, the class highlights the role that non-major introductory-level geoscience classes, in particular ones with interesting topics, can serve in educating college-level students about Earth Science. They may also serve as a gateway into the Earth Sciences for students who previously had no such inclination.

    2016-01-01

    Context: Antenatal depression is not easily visible, though the prevalence is high. The idea of conducting this study was conceived from this fact. Aims and Objectives: The aim of this study was to estimate the prevalence of antenatal depression and identify the risk factors, for early diagnosis and intervention. Settings and Design: The study conducted in a Tertiary Care Hospital was prospective and cross-sectional. Materials and Methods: Pregnant women between 18 and 40 years of age were studied. The sample size comprised 318 women. They were assessed using Edinburgh Postnatal Depression Scale (EPDS) score, Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Axis I Disorders, Life Event Stress Scale (LESS), and Life Distress Inventory (LDI). Statistical Analysis Used: The Statistical Package for Social Sciences (SPSS) Version 15 software was used to measure percentages, mean, correlation, and P < 0.05 were considered significant. Results: Prevalence of antenatal depression in the study was 12.3%. Correlation of the sociodemographic factors, obstetric factors, LDI, and LESS with EPDS scores showed statistical significance for unplanned pregnancy, distress associated with relationships, physical health, financial situation, social life, presence of personality disorder, being a homemaker, and higher educational status. Conclusion: The study showed a high prevalence rate of depression and identified risk factors. PMID:27011399

    Cinacalcet hydrochloride (cinacalcet) has been reported to be efficacious for patients with tertiary hyperparathyroidism (THPT). We experienced five patients with THPT requiring parathyroidectomy (PTx) because of resistance to cinacalcet treatment and investigated their clinical characteristics and clinical course. The maximum diameter of the parathyroid gland estimated by ultrasonography before renal transplantation was evaluated. Serum total calcium, phosphorus, intact parathyroid hormone (iPTH), alkaline phosphatase (ALP), and creatinine (Cr) levels were investigated every three months after the administration of cinacalcet and at PTx. After surgery, the Cr levels were followed. In all five patients, at least one parathyroid gland had a largest diameter of more than 1 cm, and the mean diameter was 18.7 mm (range 14.9-24.1 mm). Intact PTH and ALP levels gradually increased after the initiation of cinacalcet and the Cr levels transiently increased after PTx. These findings suggest that the existence of a severely enlarged nodular hyperplastic gland is a main factor involved in resistance to cinacalcet. PMID:21595850

  18. Comparison of anxiety levels of students in introductory earth science and geology courses

    NASA Astrophysics Data System (ADS)

    Westerback, Mary E.; Gonzalez, Clemencia; Primavera, Louis H.

    Students in geology and earth science courses were not anxious about taking these courses as measured by the State-Triat Anxiety Inventory. Students in each course were split into two grade groups. It was shown that students whose grades were in the higher group had low anxiety, which continued to be reduced during the course. Students in the lower grade group had high anxiety, which increased during the course. There was no difference between anxiety scores of males and females. In general, students who planned to elect additional courses had lower state anxiety and higher grades than students who did not plan to elect additional courses in geology and earth science.

  19. ED20. Crisis or Opportunity? Earth and Space Science Education at the State and National Levels

    NASA Astrophysics Data System (ADS)

    2011-12-01

    Scientists and researchers, those often in oversight positions and often control of the purse strings, have historically not been kind to the Earth Systems Science (ESS) discipline. This is puzzling to those of us who are ESS educators because we know that to appreciate how our planet works it is necessary to integrate and apply all the disciplines of science. With our amazing technologies and the increasing demands of a growing population we are dramatically changing our home planet. Perhaps a crisis? As the last century ended we found ESS in the same minor league position it was in when the 20th Century started. During the review period of what was to become the National Science Education Standards (NSES) draft after draft, no matter what color the cover was, seemed to ignore, omit, or severely limit ESS topics in meteorology and oceanography. Once published the NSES became the basis for the science standards in many states with what many said were critical gaps. In the years following 1996 different groups have worked to correct the omissions they found by developing guides...Ocean Literacy: Essential Principles of Ocean Science K-12 and Climate Literacy: The Essential Principals of Climate Science. An observer on the side might have considered each effort one of lobbying to get attention, funding and materials. Each effort was clearly interested in making an impact where it mattered...in the classroom. Now our Opportunity! The NAS process for developing "A Framework for K-12 Science Education" presented ESS educators with a real opportunity and we can proudly say we made our voices heard. And while there is great enthusiasm for the framework and the Chapter 7 Earth and Space we face critically important work to bring real Earth Space Science Education into the K-12 classroom. The possibility of the standards to be developed from the Framework becoming Common Core for the majority of states following the course of ELA and mathematics requires that those who previously guarded their territory collaborate.

  20. Overview of the tertiary oil recovery project

    Green, D.W.; Willhite, G.P.

    1981-01-01

    The Tertiary Oil Recovery Project (TORP) was originally proposed by the University of Kansas as a mechanism by which expertise existing in the areas of petroleum engineering and geology at the university could be brought to bear directly on the problems relating to the declining oil reserve in Kansas, and the Project was established by the Kansas legislature in 1974 for this purpose. TORP was principally established because it was realized that the continued viability of the oil industry in the state would soon be dependent in large measure on implementation of tertiary oil recovery technology. The following specific objectives were established: (1) evaluate potential of tertiary oil recovery processes in Kansas, (2) conduct research/ development on tertiary oil recovery processes applicable in the state; (3) disseminate information about the technology to the Kansas oil industry; (4) interact with oil industry representatives and provide technical assistance on field tests; and (5) educate students in tertiary oil recovery technology.

  11. Multi-Level Models of Internalizing Disorders and Translational Developmental Science: Seeking Etiological Insights that can Inform Early Intervention Strategies.

    PubMed

    Allen, Nicholas B; Dahl, Ronald E

    2015-07-01

    This commentary discusses the articles in this special section with an emphasis on the specific utility of multivariate, multi-level models in developmental psychopathology for ultimately contributing to both etiologic insights and translational advances. These issues are considered not only in terms of the specific papers, but also within a larger set of questions regarding the opportunities (and challenges) currently facing the field. We describe why we believe this an exciting time for integrative team-science approaches to tackle these challenges--a time that holds great promise for rapid advances in integrative developmental science that includes a biological level of mechanistic understanding. In order to facilitate this, we outline a range of approaches within both translational neuroscience and translational developmental science that can be used as frameworks for understanding how such research can provide etiologic insights regarding real-world targets at the level of social, behavioral, and affective processes that can be modified during key developmental windows of opportunity. We conclude that a "construct validity" framework, where biological data form a critical, but not privileged, component of key etiological mechanisms, combined with a developmental perspective on key period of sensitivity to intervention effects, is most likely to provide significant translational outcomes.

  12. Exploring How Second Grade Elementary Teachers Translate Their Nature of Science Views into Classroom Practice After a Graduate Level Nature of Science Course

    NASA Astrophysics Data System (ADS)

    Deniz, Hasan; Adibelli, Elif

    2015-12-01

    The main purpose of this study was to explore the factors mediating the translation of second grade teachers' nature of science (NOS) views into classroom practice after completing a graduate level NOS course. Four second grade in-service elementary teachers comprised the sample of this study. Data were collected from several sources during the course of this study. The primary data sources were (a) assessment of the elementary teachers' NOS views before and after the graduate level NOS course using the Views of Nature of Science Questionnaire Version B (VNOS-B) (Lederman et al., 2002) coupled with interviews, and (b) a classroom observation and videotaped recording of the elementary teachers' best NOS lessons coupled with interview. We identified three distinct but related factors that mediated the translation of NOS views into classroom practice: the teachers' perspectives about the developmental appropriateness of the NOS aspect, the teachers' selection of target NOS aspects, and the relative importance placed by teachers on each NOS aspect.

  13. The photophysics of tertiary aliphatic amines

    NASA Astrophysics Data System (ADS)

    Cureton, Clifford G.; Hara, Kiyoaki; O'Connor, Desmond V.; Phillips, David

    1981-12-01

    The fluorescence properties of the three simple tertiary amines, trimethylamine (TMA), triethylamine (TEA), and tri- n-propylamine (TPA) have been investigated in the vapour phase with particular reference to the effect of varying the excitation energy. For excitation into the lowest energy absorption band, attributed to an n ? 3s Rydberg excitation, single exponential decay characteristics were observed, whereas at higher energies simultaneous excitation of n ? 3s and n ? 3p excitations resulted in dual exponential decay. This is explained on the basis of different distributions of emitting vibronic levels of the lower Rydberg state being produced by internal conversion from the n ? 3p upper state from those produced upon direct excitation of the lower state followed by partial redistribution. As would be expected form this analysis, rate constants for radiative decay of both sets of levels are found to be identical in TMA and TEA, whereas the rate constants for non-radiative decay, assumed to be decomposition, are not identical for the two sets of levels. The analysis permits separation of the overlapping absorptions of the n ? 3s and n ? 3p Rydberg transitions in TMA and TEA.

    This report documents the delivery, installation, integration, testing, and acceptance of the Dawn system, ASC L2 milestone 3244: Deploy Dawn ID Machine for Initial Science Runs, due September 30, 2009. The full text of the milestone is included in Attachment 1. The description of the milestone is: This milestone will be a result of work started three years ago with the planning for a multi-petaFLOPS UQ-focused platform (Sequoia) and will be satisfied when a smaller ID version of the final system is delivered, installed, integrated, tested, accepted, and deployed at LLNL for initial science runs in support of SSP mission. The deliverable for this milestone will be a LA petascale computing system (named Dawn) usable for code development and scaling necessary to ensure effective use of a final Sequoia platform (expected in 2011-2012), and for urgent SSP program needs. Allocation and scheduling of Dawn as an LA system will likely be performed informally, similar to what has been used for BlueGene/L. However, provision will be made to allow for dedicated access times for application scaling studies across the entire Dawn resource. The milestone was completed on April 1, 2009, when science runs began running on the Dawn system. The following sections describe the Dawn system architecture, current status, installation and integration time line, and testing and acceptance process. A project plan is included as Attachment 2. Attachment 3 is a letter certifying the handoff of the system to a nuclear weapons stockpile customer. Attachment 4 presents the results of science runs completed on the system.

  19. Comparing levels of school performance to science teachers' reports on knowledge/skills, instructional use and student use of computers

    NASA Astrophysics Data System (ADS)

    Kerr, Rebecca

    The purpose of this descriptive quantitative and basic qualitative study was to examine fifth and eighth grade science teachers' responses, perceptions of the role of technology in the classroom, and how they felt that computer applications, tools, and the Internet influence student understanding. The purposeful sample included survey and interview responses from fifth grade and eighth grade general and physical science teachers. Even though they may not be generalizable to other teachers or classrooms due to a low response rate, findings from this study indicated teachers with fewer years of teaching science had a higher level of computer use but less computer access, especially for students, in the classroom. Furthermore, teachers' choice of professional development moderated the relationship between the level of school performance and teachers' knowledge/skills, with the most positive relationship being with workshops that occurred outside of the school. Eighteen interviews revealed that teachers perceived the role of technology in classroom instruction mainly as teacher-centered and supplemental, rather than student-centered activities.

  20. How Shall We Tell Our People? The Art and Science of Communicating Sea-Level Rise to Coastal Audiences (Invited)

    Moser, S. C.

    2010-12-01

    Improved sea-level rise projections and translation into decision-relevant information (e.g., changed flood frequencies and elevations, increased rates in coastal erosion, salinity changes in coastal aquifers) are critical for coastal managers, planners, and local elected officials to feel more confident in bringing climate change and its related coastal impacts to the attention of their communities. Those who have done so or are considering doing so, however, are not just concerned with “getting the science right” or getting the most credible and relevant information. They immediately, and sometimes primarily, are concerned with the reactions of coastal residents, developers, and business interests to the prospects of potentially difficult and substantial changes in coastal land use, their property rights, and the potential loss of their homes and establishments. How to engage the public constructively in developing adaptation strategies is a largely unmet challenge for most coastal managers. Similarly, they have not been trained in how to effectively communicate an issue that is ripe with the potential for loss, danger, and social and legal conflict - more so than they already face. Better physical science on sea-level rise alone will not meet these needs. Meanwhile, the social sciences have only begun to study public attitudes toward local impacts and adaptation responses. This paper will summarize key insights available at this time and point to important research and education/training needs to better assist practitioners faced with developing and implementing coastal adaptation strategies.

    Direct physical evidence is presented for an unusual event at exactly the time of extinctions in the planktonic realm. Deep-sea limestones exposed in Italy, Denmark, and New Zealand indicate iridium increases of about 30, 160, and 20 times, respectively, above the background level at precisely the time of the Cretaceous-Tertiary extinctions, 65 million years ago. Reasons are given that this iridium is of extraterrestrial origin, but did not come from a nearby supernova. A hypothesis is set forth which accounts for the extinctions and the iridium observations. One prediction of this hypothesis is verified, that the chemical composition of the boundary clay, which is thought to come from the stratospheric dust, is markedly different from that of clay mixed with the chemically similar Cretaceous and Tertiary limestones.

    In a secondary-level Earth System Science (ESS) curriculum, the most authentic learning is achieved through the inquiry-based application of real-world research methods in the context of modern understanding of the interconnected components of the Earth System (e.g. lithosphere, hydrosphere, atmosphere, and biosphere). Following the intensive ESST-1 summer institute at UNH, during which teachers enhance their ESS content knowledge via interactions with UNH faculty, staff, and graduate students, each participating teacher is paired with one graduate student fellow for the duration of the school year. This graduate fellow provides a continuing link between the secondary-level school teaching environment and university resources, facilitating the implementation of new content knowledge and current scientific research methodology into the classroom setting. According to the National Science Education Standards (1), scientific inquiry is the central strategy for teaching science. "In successful science classrooms, teachers and students collaborate in the pursuit of ideas... Students formulate questions and devise ways to answer them, they collect data and decide how to represent it, they organize data to generate knowledge, and they test the reliability of the knowledge they have generated. As they proceed, students explain and justify their work to themselves and to one another, learn to cope with problems such as the limitations of equipment, and react to challenges posed by the teacher and by classmates." To speak to these goals, an ongoing local wetland field study has been conceptualized and implemented in three example classrooms (seventh grade general science, ninth grade physical science and tenth grade biology) in two school systems (Oyster River Middle School in Durham, NH and Berlin High School in Berlin, NH). These field studies were conducted using authentic scientific equipment to collect data, including a Li-Cor 840 infrared CO2 analyzer and handmade sediment coring devices. Students utilized GPS and Google Earth technology both to facilitate the generation of research questions and for accurate geographic location during their field studies. An emphasis was placed on maintaining organized records of observations and data using field notebooks. Every site visit was followed by teacher-guided data analyses, and students communicated their results through a variety of formats, including posters, written reports, and oral presentations. These authentic research experiences create an initial data set which may be referenced in future classroom studies, while effectively engaging students in ESS topics that meet national and state educational standards.

    The West Hackberry Tertiary Project is a field test of the concept that air injection can generate tertiary oil recovery through the Double Displacement Process. The Double Displacement Process is the gas displacement of a water invaded oil column for the purpose of recovering tertiary oil through gravity drainage. The novel aspect of this project is the use of air as the injection fluid. In Gulf Coast oil reservoirs with pronounced bed dip, reservoir performance has shown that gravity drainage recoveries average 80% to 90% of the original oil in place while water drive recoveries average 50% to 60% of the original oil in place. The target for tertiary oil recovery with the Double Displacement Process is the incremental oil between the 50% to 60% water drive recoveries and the 80% to 90% gravity drainage recoveries.

    2012-02-01

    RNAs have been found to be involved in the biological processes. The large RNA usually consists of two basic elements: RNA hairpins and duplex. Due to the experimental determination difficulties, the few RNA tertiary structures limit our understanding of the specific regulation mechanisms and functions. Therefore, RNA tertiary structure prediction is very important for understanding RNA biological functions. Since RNA often folds hierarchically, one of the possible RNA structure prediction approaches is through the hierarchical steps. Here, we focus on the prediction method of RNA tertiary hairpin and duplex structures in which assembles the small tertiary structure fragments from well-defined RNA structural motifs. In a benchmark test with known experiment structures, more than half of the cases agree with the experimental structure better than 3 å RMSD over all the heavy atoms. The prediction results also reproduce the native like complementary base pairs of the secondary structures. Most importantly, the method performs the atomic accuracy of tertiary structures by about several minutes. We expect that the method will be a useful resource for RNA tertiary structure prediction and helpful to the biological research community.

  7. The concept of landscape education at school level with respect to the directions of the science of landscape

    2010-01-01

    School education is both a starting point for the development of various scientific disciplines (school educates future researchers) and the result of science. The landscape research is conducted within many scientific disciplines and has a long tradition. Lanscape education, which is the result of a scientific dimension, is implemented in primary school under the nature subject. Primary school education is the only level at which the geographical contents are carried out on landscape. The landscape is of interest to many disciplines: geography, architecture, social sciences and the arts. In recent years, there were many studies which contained an overview of the main strands of the science of landscape, presented the differences in the meaning of the concept and objectives of individual research disciplines. These studies have become the ground for the characterization of the concept of landscape education implemented in Polish school and its evaluation in terms of scientific achievements. A review of educational purposes, the basic content of education and achievements of students, demonstrate the influence of multiple scientific disciplines in school landscape education. The most significant share of the course content are achievements of geography disciplines, particularly: physical geography, environmental protection and landscape ecology. Other scientific fields: literature, art, psychology, sociology, and architecture do not have any impact on the school landscape education or their impact remains marginal.

  8. The impact of an introductory college-level biology class on biology self-efficacy and attitude towards science

    NASA Astrophysics Data System (ADS)

    Thomas, Megan Elizabeth

    Self-efficacy theory was first introduced in a seminal article by Albert Bandura in 1977 entitled "Self-efficacy: Toward a unifying theory of behavioral change". Since its original introduction, self-efficacy has been a major focus of academic performance, anxiety, career development, and teacher retention research. Self-efficacy can be defined as the belief an individual possesses about their ability to perform a given task. Bandura proposed that self-efficacy should be measured at the highest level of specificity due to the fact that different people are efficacious in different areas. Interested in students' efficacy toward biology, Ebert-May, Baldwin, & Allred (1997) created and validated a survey to measure students' biology self-efficacy. Their survey was modeled after the guidelines for science literacy, and loaded to three sub-factors; methods of biology, generalization to other science courses, and application of the concepts. As self-efficacy theory has been related to effort expenditure and persistence (Bandura, 1977; 1997), one might think it would have some effect on students' attitudes toward the topic at hand. The current research investigated what changes in biology self-efficacy occurred after an introductory biology course with an inquiry based laboratory learning environment. In addition, changes in students' attitudes towards science were explored and how self-efficacy might affect them.

    This article describes a proposal for a nursing curriculum in general, clinical and paediatric nursing sciences (this scientific area is named MED/45 in Italian legislation) at the first cycle of higher education for general nurses in Italy (level 6 according to the European Qualifications Framework). Future change in university syllabus, need to revise nursing curriculum starting from specific competences acquisition, lack of professional national nursing standards, and uncertain evolution of a scientific academic sector for nurses in Italy, led to this work. It consists in evaluation and revision of what has been implemented in a nursing pre-registration degree at University of Insubria. Key principles orienting nursing sciences educational activities revision of this degree course has been the following: centrality of the person in the curing process, choice of a conceptual nursing model to guide personalisation of care, development of therapeutic relationship skills, and adherence to professional principles and values. Aims, educational objectives, and educational activities planned to teach nursing discipline in the three year course, are presented in this paper. Nursing discipline has been articulated into four knowledge areas: general nursing, nursing methodology, clinical nursing (general and applied), advanced nursing practice. Evaluation of this curriculum, implemented since 2000 and modified in 2008, helped the students to acquire a clear professional identity. Further comments are added in the conclusion on matching educational objectives to didactic units, identification of four knowledge areas for nursing sciences, and choice to deal with advanced nursing practice during the third year of the degree course.

    2014-06-15

    There are controversies surrounding radiation effects in human population in the range of radiation doses encountered by patients resulting from one to several CT scans. While it is understandable why the effects from low levels of diagnostic radiation are controversial, the situation is complicated by the media which may distort the known facts. There is need to understand the state of science regarding low-level radiation effects and also to understand how to communicate the potential risk with patients, the public and media. This session will seek to come to a consensus in order to speak with one voice to the media and the public. This session will review radiation effects known so far from a variety of exposed groups since the nuclear holocaust, provide clarification where effects are certain and where they are not, at what level extrapolation is the only way and at what level there is weak but agreeable acceptance. We will depict where and why there is agreement among organizations responsible for studying radiation effects, and how to deal with situations where effects are uncertain. Specific focus on radiation effects in children will be provided.Finally, the session will attempt to bridge the communication gap from the science to how to be an effective communicator with patients, parents, and media about ionizing radiation. Learning Objectives: To have a clear understanding about certainties and uncertainties of radiation effects at the level of a few CT scans To understand the results and limitations from 3 major pediatric CT scientific studies on childhood exposures published recently. To understand successful strategies used in risk communication.

  11. Change in science teaching behaviors: Evaluating the impact of a collaborative learning network at the level of practice

    NASA Astrophysics Data System (ADS)

    Carroll, Teresa Mae

    This study reports the results of research designed to explore the impact of a science and technology collaborative network called the Kansas Collaborative Research Network (KanCRN) on the teaching practices of Kansas City, Kansas elementary and middle school science teachers. Research questions were developed around the theory that collaborative networks provide teachers the kind of support they need to create contexts conducive to change. Hence, research questions first dealt with determining whether teachers, who had participated in the network for two years, reported changes in their teaching practices. Subsequent questions asked teachers to describe these changes and to describe the role KanCRN played in the change process. Analysis, during the first phase of the investigation, was based on the KanCRN Teacher Practice Survey Data. Data analysis revealed that change in teacher practice had occurred. The second phase of the investigation sought to build a descriptive picture of the role KanCRN played in the change process. Interview data revealed that teachers described changes in their teaching practices concurrent with those specified by science education reform documents. KanCRN teachers also noted personal changes in pedagogical skill, and science content knowledge. These changes served as a catalyst for the behavioral changes cited. Moreover, teachers expressed changes in their views of the nature of science that also transferred to the types of classroom teaching behaviors now employed. Teachers credited network participation as the force behind the change. Teachers cited (a) challenging pedagogical and technological training, (b) interactive real world experiences with science content, (c) progressive technological tools and materials, and (d) personal guidance from mentors who respected and valued teachers as knowledgeable professionals critical for promoting change. One conclusion drawn from this study is that collaborative networks are capable on influencing the types of teaching behaviors used by elementary and middle school teachers. However, network offerings must employ a combination of adaptable features that meet the individual learning needs of the teachers as well as the individual contextual they serve. Another major conclusion drawn from this study is that to be successful agents of change, collaborative networks must allow teachers to behave in ways atypical of most change efforts. First, participation in collaborative networks must be participatory. Moreover, teachers must be able to participate as they deem fit. There can be no predetermined prescription for level of participation. Second, network facilitators or activities should not be intent on bringing a teacher to a particular standard of behavior. Finally, teachers must be allowed to construct the network elements intended to change their practice. (Abstract shortened by UMI.)

    Teaching students, aged from 4 up to 18 years old, is a challenging task. It continuously implies new strategies and new subjects adapted to all of them. This is even more evident, when we have to teach natural-hazards scientific aspects and safe attitudes toward risk. We often see that most of the high-school students (16 -18 years old) are not motivated for extra-curricular activities implying science and/or behaviours changes. But, they have a very positive response when we give them some responsibility. On top of that, we also realised that young children are quite receptive to the involvement of older students in the school environment Taking this into consideration, our project use the k12 students to prepare scientific activities and subjects, based in questions, which they need to answer themselves. The students need to answer those questions and, only then, adapt and teach the right answers to the different school-levels. With this approach, we challenged the students to solve three questions: How to use a SEP seismometer at school, and its data? How to set up a shaking table? How to introduce waves and vibrations contents to all ages of students? During the project they developed many science skills, and worked in straight cooperation with teachers, the parents association and the seismology research group at Instituto Dom LuĆ­z. As a result, it was possible to reach all school students with the help of the k-12 ones. This is an outcome of the project W-Shake, a Parents-in-Science Initiative to promote the study of seismology and related subjects. This project, supported by the Portuguese "CiĆŖncia Viva" program, results from a direct cooperation between the parents association, science school-teachers and the seismology research group at Instituto Dom LuĆ­z.

  17. Latitudinal gradients in tertiary molluscan faunas of the Pacific coast

    USGS Publications Warehouse

    Addicott, W.O.

    1970-01-01

    Tertiary molluscan faunas of the middle latitudes of the marginal eastern North Pacific are characterized by warm-water taxa whose descendants now live in more southerly latitudes. A series of profiles in which cumulative percentages of warm-water faunal elements are plotted against latitude show progressive northward decreases in the percentage of these elements in the faunas of Pacific coast Tertiary stages. Systematic changes in the relative position of these latitudinal gradients during the Middle and Late Tertiary are related to climatic change in the Pacific Basin. Widespread tropical marine climate in the middle latitudes of the eastern North Pacific during the Eocene is indicated by widespread faunal units characterized by high levels of taxonomic diversity. Succeeding Early Oligocene faunas are less diverse, suggesting cooler climatic conditions. Unusually low representations of warm-water genera characterize the molluscan faunas of the Acila shumardi Zone in central California (latitude 34??-37??N). The anomalously cool-water aspect of these faunas may record the occurrence of upwelling along a bold linear segment of the Pacific coast. During the Late Oligocene or the Early Miocene, they are replaced by faunas of unusually warm-water aspect resulting in positive anomalies in Miocene latitudinal faunal gradients in central California. The Miocene anomalies seem to result from the development of an irregular Neogene coastline with extensive, newly established shallow-water embayments. ?? 1970.

  1. System-Level Verification of Science Instruments Prior to Installation at TMT

    NASA Astrophysics Data System (ADS)

    Ebbets, Dennis; Lystrup, Makenzie

    2014-07-01

    Science instruments for TMT will share many similarities with those built for large space observatories such as HST and JWST. They will be physically large, scientifically sophisticated and technologically complex. They will represent very significant investments of time and money by PI-led teams with common scientific interests, but from many academic institutions, industry partners and even nations. These teams will verify the basic functionality and performance of their instruments, but may not each have facilities to test the many complex interfaces to and interactions with the observatory. Once installed on the telescope and commissioned, the instruments will be expected to function for many years with very limited opportunities for servicing. These and other considerations argue that a common facility that provides reasonably high fidelity simulation of the TMT mechanical and optical environments, AO system interfaces, operations and data management systems and other critical functions would enable a confidence-building final step in the Integration and Test process. This poster illustrates how high-quality Ground Support Equipment was used to prepare seven instruments for Hubble, develop and validate wave-front sensing and control algorithms for James Webb, simulate the optical characteristics of JWST, conduct vibration and modal surveys, and produce performance data that were compared with predictions of integrated models. Analogous capabilities could be developed to support TMT, ensuring delivery of fully qualified instruments to the observatory.

  2. Taking Social Media Science Myth Debunking to a Presidential Level (Invited)

    NASA Astrophysics Data System (ADS)

    Nuccitelli, D. A.; Cook, J.

    2013-12-01

    Climate science myths are often effective and pervasive because they are "sticky" - simple, concrete, and seemingly credible. For example, "there's no consensus" and "global warming stopped in 1998" are appealing myths because they present a simple alternative narrative to the threat posed by anthropogenic global warming. In order to effectively debunk these types of myths, sticky ideas must be replaced with even stickier and accurate alternative explanations. The seeming limitations of social media may actually be considered an asset, requiring that our messaging be simple, brief, and sticky. Here some examples of successful debunkings of scientific myths using social media are presented and examined. The 'no consensus' myth was effectively debunked through simple messaging of Cook et al. (2013), which found 97% consensus among papers taking a position in the peer-reviewed literature on human-caused global warming. This simple and sticky '97% consensus' has been communicated widely through social media, including twice by President Obama's Twitter account. The 'global warming stopped' myth has been frequently and effectively debunked by a simple animated graphic titled 'The Escalator', which has been used on the floor of the US Senate and in a PBS documentary. Here we examine how these debunkings via social media were successful, and how scientists can replicate their success. President Obama tweet of the 97% consensus message The Escalator

    2007-01-01

    The study aims to characterize contextual learning during class visits to science and natural history museums. Based on previous studies, we assumed that outdoor learning is different from classroom-based learning, and free choice learning in the museums enhances the expression of learning in personal context. We studied about 750 students participating in class visits at four museums, focusing on the levels of choice provided through the activity. The museums were of different sizes, locations, visitor number, and foci. A descriptive-interpretative approach was adopted, with data sources comprising observations, semistructured interviews with students, and museum worksheets. Analysis of the museum activities has yielded four levels of choice that affect learning from no choice to free choice activities. The effectiveness of learning was examined as well by looking at task behavior, linkage to the students' prior knowledge and their school's science curriculum, and linkage to the students' life and experience. Our findings indicate that activities of limited choice offered scaffolding, allowed the students to control their learning, and enhanced deeper engagement in the learning process. Within all the choice opportunities, the students connected the visit to their own life experiences and to their prior knowledge, even when the guided activity scarcely addressed it. Critical responses were obtained mainly when the museum environment allows a variety of learning opportunities without directing the students.

    2015-12-01

    Like it is the case for many large projects, XMM-Newton data have been used by the community to produce many valuable higher level data products. However, even after 15 years of the successful mission operation, the potential of these data is not yet fully uncovered, mostly due to the logistical and data management issues. We present a web application, http://xmm-catalog.irap.omp.eu, to highlight an idea that existing public high level data collections generate significant added research value when organized and exposed properly. Several application features such as access to the all-time XMM-Newton photon database and online fitting of extracted sources spectra were never available before. In this talk we share best practices we worked out during the development of this website and discuss their potential use for other large projects generating astrophysical data.

  13. Science PhD Career Preferences: Levels, Changes, and Advisor Encouragement

    PubMed Central

    Sauermann, Henry; Roach, Michael

    2012-01-01

    Even though academic research is often viewed as the preferred career path for PhD trained scientists, most U.S. graduates enter careers in industry, government, or “alternative careers.” There has been a growing concern that these career patterns reflect fundamental imbalances between the supply of scientists seeking academic positions and the availability of such positions. However, while government statistics provide insights into realized career transitions, there is little systematic data on scientists' career preferences and thus on the degree to which there is a mismatch between observed career paths and scientists' preferences. Moreover, we lack systematic evidence whether career preferences adjust over the course of the PhD training and to what extent advisors exacerbate imbalances by encouraging their students to pursue academic positions. Based on a national survey of PhD students at tier-one U.S. institutions, we provide insights into the career preferences of junior scientists across the life sciences, physics, and chemistry. We also show that the attractiveness of academic careers decreases significantly over the course of the PhD program, despite the fact that advisors strongly encourage academic careers over non-academic careers. Our data provide an empirical basis for common concerns regarding labor market imbalances. Our results also suggest the need for mechanisms that provide PhD applicants with information that allows them to carefully weigh the costs and benefits of pursuing a PhD, as well as for mechanisms that complement the job market advice advisors give to their current students.

  15. Students' Perspectives on Worldwide ``Greening'' of Tertiary Education Curricula

    NASA Astrophysics Data System (ADS)

    2010-11-01

    Several scholars have suggested the introduction of an environmental literacy requirement into the curricula of Non-Environmental Science disciplines in tertiary institutions of the world as a “greening” strategy for fostering global environmental stewardship necessary for enhancing understanding and collaboration in tackling the major environmental risks facing our global village today. However, there is no study on students’ opinion on this issue. This study was therefore initiated to 1) evaluate the opinion of undergraduate students on the introduction of a worldwide environmental literacy into the curricula of Non-Environmental science majors as a graduation requirement; and 2) identify any possible demographic differences in opinions among the student subjects polled. We sought the opinion of 800 undergraduates from African, North American and European universities on the subject and 99% responded. The result showed that a majority (67%) of them supported the worldwide environmental literacy requirement and those already trained were significantly ( P < 0.0001) more likely to support it than those untrained. Students from developing countries were significantly ( P < 0.0001) more likely to support it than those from developed countries; similarly students in the Arts’ disciplines were more likely to support it than Non-Arts’ students as a group. However, no significant differences were observed between students from Francophone versus Anglophone countries; Social Sciences versus Non-Social Sciences majors and between Education versus Non-Education majors. Some similarities were observed between the opinion of university-age students in this study and 15-year old secondary school students from two major international surveys (Research on Science Education-ROSE, and Program for International Student Assessment-PISA) on science education; further studies comparing these two categories of students is suggested. The need for all professionals to be literate about the science of their surroundings was the most identified reason for supporting the literacy requirement by the students polled. The results of this study thus provide evidence of support by students in the on-going paradigm shift towards “greening” the curricula of tertiary institutions and thus reinforces its implementation by leaders of academe and policy makers worldwide.

  16. A multi-level differential item functioning analysis of trends in international mathematics and science study: Potential sources of gender and minority difference among U.S. eighth graders' science achievement

    NASA Astrophysics Data System (ADS)

    Qian, Xiaoyu

    Science is an area where a large achievement gap has been observed between White and minority, and between male and female students. The science minority gap has continued as indicated by the National Assessment of Educational Progress and the Trends in International Mathematics and Science Studies (TIMSS). TIMSS also shows a gender gap favoring males emerging at the eighth grade. Both gaps continue to be wider in the number of doctoral degrees and full professorships awarded (NSF, 2008). The current study investigated both minority and gender achievement gaps in science utilizing a multi-level differential item functioning (DIF) methodology (Kamata, 2001) within fully Bayesian framework. All dichotomously coded items from TIMSS 2007 science assessment at eighth grade were analyzed. Both gender DIF and minority DIF were studied. Multi-level models were employed to identify DIF items and sources of DIF at both student and teacher levels. The study found that several student variables were potential sources of achievement gaps. It was also found that gender DIF favoring male students was more noticeable in the content areas of physics and earth science than biology and chemistry. In terms of item type, the majority of these gender DIF items were multiple choice than constructed response items. Female students also performed less well on items requiring visual-spatial ability. Minority students performed significantly worse on physics and earth science items as well. A higher percentage of minority DIF items in earth science and biology were constructed response than multiple choice items, indicating that literacy may be the cause of minority DIF. Three-level model results suggested that some teacher variables may be the cause of DIF variations from teacher to teacher. It is essential for both middle school science teachers and science educators to find instructional methods that work more effectively to improve science achievement of both female and minority students. Physics and earth science are two areas to be improved for both groups. Curriculum and instruction need to enhance female students' learning interests and give them opportunities to improve their visual perception skills. Science instruction should address improving minority students' literacy skills while teaching science.

  19. Cooperative Tertiary Interaction Network Guides RNA Folding

    SciTech Connect

    Behrouzi, Reza; Roh, Joon Ho; Kilburn, Duncan; Briber, R.M.; Woodson, Sarah A.

    2013-04-08

    Noncoding RNAs form unique 3D structures, which perform many regulatory functions. To understand how RNAs fold uniquely despite a small number of tertiary interaction motifs, we mutated the major tertiary interactions in a group I ribozyme by single-base substitutions. The resulting perturbations to the folding energy landscape were measured using SAXS, ribozyme activity, hydroxyl radical footprinting, and native PAGE. Double- and triple-mutant cycles show that most tertiary interactions have a small effect on the stability of the native state. Instead, the formation of core and peripheral structural motifs is cooperatively linked in near-native folding intermediates, and this cooperativity depends on the native helix orientation. The emergence of a cooperative interaction network at an early stage of folding suppresses nonnative structures and guides the search for the native state. We suggest that cooperativity in noncoding RNAs arose from natural selection of architectures conducive to forming a unique, stable fold.

    1987-03-01

    The various geological signatures at Cretaceous/Tertiary time including iridium and other associated elements, microspherules, and shock deformation features are compatible with the suggestion that the transition is marked by a period of intense volcanism. The volatile emissions from this volcanism would lead to acid rain, reduction in the alkalinity and pH of the surface ocean, global atmospheric temperature changes, and ozone layer depletion. These environmental effects coupled with those related to the major sea level regression of the late Cretaceous provide the framework for an explanation of the selective nature of the observed extinction record.

  1. From Ramachandran Maps to Tertiary Structures of Proteins.

    PubMed

    DasGupta, Debarati; Kaushik, Rahul; Jayaram, B

    2015-08-27

    Sequence to structure of proteins is an unsolved problem. A possible coarse grained resolution to this entails specification of all the torsional (?, ?) angles along the backbone of the polypeptide chain. The Ramachandran map quite elegantly depicts the allowed conformational (?, ?) space of proteins which is still very large for the purposes of accurate structure generation. We have divided the allowed (?, ?) space in Ramachandran maps into 27 distinct conformations sufficient to regenerate a structure to within 5 Å from the native, at least for small proteins, thus reducing the structure prediction problem to a specification of an alphanumeric string, i.e., the amino acid sequence together with one of the 27 conformations preferred by each amino acid residue. This still theoretically results in 27(n) conformations for a protein comprising "n" amino acids. We then investigated the spatial correlations at the two-residue (dipeptide) and three-residue (tripeptide) levels in what may be described as higher order Ramachandran maps, with the premise that the allowed conformational space starts to shrink as we introduce neighborhood effects. We found, for instance, for a tripeptide which potentially can exist in any of the 27(3) "allowed" conformations, three-fourths of these conformations are redundant to the 95% confidence level, suggesting sequence context dependent preferred conformations. We then created a look-up table of preferred conformations at the tripeptide level and correlated them with energetically favorable conformations. We found in particular that Boltzmann probabilities calculated from van der Waals energies for each conformation of tripeptides correlate well with the observed populations in the structural database (the average correlation coefficient is ?0.8). An alpha-numeric string and hence the tertiary structure can be generated for any sequence from the look-up table within minutes on a single processor and to a higher level of accuracy if secondary structure can be specified. We tested the methodology on 100 small proteins, and in 90% of the cases, a structure within 5 Å is recovered. We thus believe that the method presented here provides the missing link between Ramachandran maps and tertiary structures of proteins. A Web server to convert a tertiary structure to an alphanumeric string and to predict the tertiary structure from the sequence of a protein using the above methodology is created and made freely accessible at http://www.scfbio-iitd.res.in/software/proteomics/rm2ts.jsp.

    2013-04-01

    The purpose of this action research was to increase the mastery level of Form Five Social Science students in Tawau II National Secondary School in the operations of addition, subtraction and multiplication of matrices in Mathematics. A total of 30 students were involved. Preliminary findings through the analysis of pre-test results and questionnaire had identified the main problem faced in which the students felt confused with the application of principles of the operations of matrices when performing these operations. Therefore, an action research was conducted using an intervention programme called "G.P.S Matrices" to overcome the problem. This programme was divided into three phases. 'Gift of Matrices' phase aimed at forming matrix teaching aids. The second and third phases were 'Positioning the Elements of Matrices' and 'Strenghtening the Concept of Matrices'. These two phases were aimed at increasing the level of understanding and memory of the students towards the principles of matrix operations. Besides, this third phase was also aimed at creating an interesting learning environment. A comparison between the results of pre-test and post-test had shown a remarkable improvement in students' performances after implementing the programme. In addition, the analysis of interview findings also indicated a positive feedback on the changes in students' attitude, particularly in the aspect of students' understanding level. Moreover, the level of students' memory also increased following the use of the concrete matrix teaching aids created in phase one. Besides, teachers felt encouraging when conducive learning environment was created through students' presentation activity held in third phase. Furthermore, students were voluntarily involved in these student-centred activities. In conclusion, this research findings showed an increase in the mastery level of students in these three matrix operations and thus the objective of the research had been achieved.

    NASA Astrophysics Data System (ADS)

    Terry, Brian H.

    In this quasi-experimental study, the researcher investigated the effectiveness of three tactual strategies and one non-tactual strategy of content specific vocabulary acquisition. Flash cards, task cards, and learning wheels served as the tactual strategies, and vocabulary review sheets served as a non-tactual strategy. The sample (n=85) consisted of all middle school students in a small high performing middle school located in the northern suburbs of New York City. All of the vocabulary words and terms came from the New York State Intermediate Level Science Core Curriculum. Pre-tests and post-tests were used to collect the data. A repeated measures ANOVA was conducted on the gain scores from each of the treatments. Multiple paired sample t-tests were conducted to analyze the results. Repeated measures ANOVAs were used to determine if there was a variance between the academic achievement levels of the students, gender, and grade level for each of the treatments. All of the treatments significantly improved the science achievement of the students, but significance was found between them. Significance was found between the achievement groups with the above average students attaining a higher mean on the pre-test and post-test for each treatment, whereas the below average students had the lowest mean on both assessments. The sixth grade students showed significant improvement over the seventh grade students while using the flash cards (p=.004) and learning wheel (p=.007). During the learning wheel treatment, the males scored significantly better (p=.021) than the females on the pre-test and post-test. During the worksheet treatment, significance (p=.034) was found between gender and achievement group. The below average male students had the greatest gain from the pre-test to the post-test, but the post-test mean was still the lowest of the groups. Limitations, implications for future research and current practice are discussed. Key words are: flash cards, task cards, learning wheel, tactual strategy, vocabulary acquisition.

  6. Early Tertiary climates of the Arctic Ocean

    Marincovich, L.; Zinsmeister, W.J.

    1985-01-01

    Knowledge of Early Tertiary high latitude marine faunas (north of 65 N) is extremely limited. What published data that are available were based on small collections obtained during the early part of the 20th century. Recent work along the western part of the Arctic Ocean has greatly increased the knowledge of the composition of these faunas and climatic conditions of the high northern latitudes during the Early Tertiary. Early Eocene shallow marine faunas from the Eureka Sound Formation, Ellesmere Island (79/sup 0/ 30'N), together with similar aged faunas from Ocean Point, Alaska (72/sup 0/N) and Spitsbergen trough, Svalbard, (78/sup 0/N) indicate that temperature conditions prevailed in the high Arctic during the early Tertiary. These high latitude temperate conditions are also supported by the presence of a diverse terrestrial mammalian faunas (currently known only from Ellesmere Island) and floras. Preliminary comparisons of these faunas from the Arctic ocean with the diverse subtropical faunas from West Greenland (70/sup 0/N) indicates the presence of a major faunal discontinuity existed in the high northern latitudes during the early Tertiary. The cause of this faunal discontinuity is uncertain. It may be due to the presence of a physical barrier between the Arctic Ocean and the North Atlantic or it may reflect cooler climatic conditions north of 70 N.

  13. Organizing Science Popularization and Teacher Training Workshops : A Nigerian Experience

    NASA Astrophysics Data System (ADS)

    Okpala, Kingsley; Okere, Bonaventure

    Funding for science popularization has become a huge challenge in recent times especially for developing countries like Nigeria. However, a change in the school system from the 6-3-3-4 system (6 years primary, 3 years Junior secondary, 3year senior secondary, and 4 years tertiary education) to the 9-3-4 system ( 9 years junior basic, 3 years secondary, and 4 tertiary education) has made it even more convenient to strategically target the students through their teachers to attain the desired quality of education since the introduction of space science into the curriculum at the primary and secondary levels. Considering the size of Nigeria, there Is need for a shift in paradigm for sourcing resources to tackle this deficiency in a sustainable manner. Recently a teacher training and science popularization workshop was organized as a first in a series of subsequent workshops geared towards having a sustainable means of popularizing Science in Nigeria. Principally, the key lies in the partnership with the colleges of education which produce the teachers for primary schools in addition to the usual governmental actions. Experiences from this workshop will be enumerated with the hope of inspiring the same success in similar societies.

  14. An Application of the Questionnaire on Teacher Interaction and College and University Classroom Environment Inventory in a Multicultural Tertiary Context

    NASA Astrophysics Data System (ADS)

    Coll, Richard K.; Taylor, Neil; Fisher, Darrell L.

    2002-02-01

    The research reported in this inquiry consisted of the application of two classroom learning environment questionnaires developed in a Western context to a culturally diverse context, namely, the Pacific Islands. The College and University Classroom Environment Inventory (CUCEI) and Questionnaire on Teacher Interaction (QTI) instruments were administered to intact classes of first- and second-year science students ( n= 257) at a regional university in the Pacific Islands, containing a total of 12 ethnicities. The data reveal that the QTI instrument holds good reliability for all scales, whereas the CUCEI holds reliability for only two scales. This may be due to the simple nature of the questions on the QTI whereas the questions on the CUCEI require more interpretation, the latter exacerbated by the fact that English is a second or third language for most participants. Surprisingly, there were few differences in perceptions of teacher student interaction based on ethnicity, but substantial differences based on gender. As reported in previous classroom environment research at the secondary school level, in this study, females perceived their environment more favourably than males. The data for the QTI reveal that the students perceive their classrooms to be highly teacher dominated, consistent with previous naturalistic studies of secondary schools and exploratory studies at the tertiary level in Fiji. Since almost all the graduates from this institution become science teachers, a cycle is completed.

  15. Assessing the energy and environmental performance of algae-mediated tertiary treatment of estrogenic compounds.

    2015-02-01

    This study uses a systems-level modeling approach to illustrate a novel synergy between municipal wastewater treatment and large-scale algaculture for production of bio-energy, whereby algae-mediated tertiary treatment provides efficient removal of unregulated, strongly estrogenic steroid hormones from the secondary effluent. Laboratory results from previously published studies suggested that algae-mediated treatment could deliver roughly 75-85% removal of a model estrogen (17?-estradiol) within typical algae pond residence times. As such, experimental results are integrated into a comprehensive life cycle assessment (LCA) framework, to assess the environmental performance of an algae-based tertiary treatment system relative to three conventional tertiary treatments: ozonation, UV irradiation, and adsorption onto granular activated carbon. Results indicate that the algae-mediated tertiary treatment is superior to the selected benchmarks on the basis of raw energy return on investment (EROI) and normalized energy use per mass of estrogenic toxicity removed. It is the only tertiary treatment system that creates more energy than it consumes, and it delivers acceptable effluent quality for nutrient and coliform concentrations while rendering a significant reduction in estrogenic toxicity. These results highlight the dual water and energy sustainability benefits that accrue from the integration of municipal wastewater treatment and large-scale algae farming. PMID:25537081

  16. Palynological and iridium anomalies at Cretaceous-Tertiary boundary, south-central Saskatchewan

    1986-01-01

    The Cretaceous-Tertiary boundary in south-central Saskatchewan is marked by coincident anomalies in abundance of iridium and fern spores at the extinction level of a suite of Cretaceous pollen taxa. Evidence of disruption of the terrestrial flora includes the fern-spore abundance anomaly and local extinction of as much as 30 percent of angiosperm species. The reorganized earliest Tertiary flora is made up largely of surviving species that assumed new roles of dominance. Persistence of climatically sensitive taxa across the boundary indicates that if paleoclimate was altered by the terminal Cretaceous event, it returned quickly to the pre-event condition.

  17. Tertiary dendritic instability in late stage solidification of Ni-based superalloys

    NASA Astrophysics Data System (ADS)

    Franke, M. M.; Singer, R. F.; Steinbach, I.

    2014-03-01

    Derivatives of the commercial alloy CMSX-4 were directionally solidified and characterized with respect to their final dendrite microstructure. The results indicate that Ni-based superalloys with high segregation levels show significant instability in secondary dendrite arms and an increased tendency for tertiary arm formation, respectively. Phase-field simulations were used to explore the impact of chemical composition on morphological instability and tertiary arm formation during the directional solidification of Ni-based superalloys. It is found that an increase in specific alloying elements in the overall alloy composition leads to pronounced segregation at the end of solidification. This causes strong growth restriction of the secondary arms and triggers tertiary arm formation. The proposed mechanism explains experimental microstructures found in modifications of the base alloy CMSX-4.

    2014-12-01

    During one 17 month period ending October 2013, three major reports on sea level rise from three highly respected science providers produced three differing, in some cases wildly divergent, estimates of sea level rise through the year 2100. These reports, by the National Research Council, the IPCC, and the National Climate Assessment, collectively flummoxed the lay reader seeking direction on sea level rise projections to incorporate into adaptation planning. Guidance documents soon emerged from state entities, including regulatory agencies, which caused further confusion. The City and County of San Francisco, surrounded by water on three sides, began developing City-wide sea level rise guidance in 2013. A Sea Level Rise Committee featuring representatives of key infrastructure managers met over a nine month period, and their work included an in-depth review of the science of sea level rise. To convert divergent scientific reports into "actionable science" required not only a close reading of each but extensive expert elicitation to tease out the meaning behind each of the numbers and the associated uncertainties. In the end, sufficient consistency between the differing projections, fortified by political exigencies, allowed a "scientific consensus" with actionable science value for the City to surface. The resulting document, "Guidance for Incorporating Sea Level Rise into Capital Planning in San Francisco," begins by providing a scientific underpinning for planning, guidelines for incorporating uncertainty - particularly for accommodating multiple projections for any particular time slice - and outlines a four step process for assessment and adaptation. It also relies on new state-of-the-art inundation maps produced as part of the SFPUC's capital improvement program. Together, the Guidance and associated tools provide a road map for successful assessment and adaptation to sea level rise. We will also draw lessons from the experience that may be of value to science leaders seeking to make contributions in the decision making domain.

  10. A Delphi study: Practitioners' perceptions of how the science curriculum is differentiated for academically gifted students at the middle school level

    NASA Astrophysics Data System (ADS)

    Kelley, Jean Mary

    The purpose of this study was to identify, analyze, and compare the perceptions of selected district science educators and teachers of middle school science students regarding the following issues: (1) Current methods of differentiating science instruction for gifted middle school students. (2) Strengths of the current methods of differentiating science instruction for gifted middle school students. (3) Weaknesses of the current methods of differentiating science instruction for gifted middle school students. (4) The types of training/experience needed to prepare teachers to effectively differentiate science instruction for gifted middle school students. (5) The steps need to develop an effective differentiated science program at the middle school level. (6) Trends for the future development of differentiated science programs at the middle school level. The panel of educators was identified using the Delphi technique and asked to participate in the study by responding to the research questions. The responses to the first round were condensed into two lists of discrete statements, and in the second round, each group of panelists was asked to rank each statement on a Likert scale. A third round was sent to each group of panel members showing the median and interquartile ranges of the second round. Panelists could adjust their responses based on the results of the second round. The analysis of the data was computed using the computer program Statistics Package for the Social Sciences. Based on the data obtained, the following results and conclusions were determined. The coordinators and the teachers both considered training of teachers, strategies for differentiation, and future trends to be the most important considerations. The areas with the most differences were those dealing with the current methods of differentiating science instruction at the middle school level. There were several limitations identified in this study. Among them were the makeup of the sample of panelists and different definitions of the same term(s). If we are to address the needs of middle school students who are academically gifted in science, teachers and coordinators need to communicate more about expectations in the classroom and what is really happening.

  11. On the importance for climate science communication - the climate office for polar regions and sea level rise

    NASA Astrophysics Data System (ADS)

    Treffeisen, Renate; Lemke, Peter; Dethloff, Klaus

    2010-05-01

    Climate change presents a major challenge for national and international action and cooperation. A wide variation in the vulnerability is to be expected across different regions, due to regional differences in local environmental conditions, preexisting stresses to ecosystems, current resource-use patterns, and the framework of factors affecting decision-making including government policies, prices, preferences, and values. Thus, considerable regional impact differences will be faced as a result of climate change. Being aware will help to prepare for these inevitable consequences in time. Climate change is nowhere more strongly expressed than in the polar regions which respond to even small changes in climate. Given the major role played by these regions within the Earth's climate system the climate office for polar regions and sea level rise is hosted by the Foundation Alfred Wegener Institute for Polar and Marine Research (AWI) which conducts research in the Arctic, the Antarctic and at temperate latitudes since 1980. The major goal of the climate office is to encourage the communication and dialogue between science and public. Primarily, this is done by the unique close contact and cooperation to the research center scientists. A continuous exchange is supported beyond the research center towards universities and authorities at state and federal level. The climate office represents polar aspects of climate related research based on the scientific expertise from the hosting research institute e.g. the understanding of the ocean-ice-atmosphere interactions, the animal and plant kingdoms of the Arctic and Antarctic, and the evolution of the polar continents and seas. The climate office translates the scientific work into English, making complex issues accessible to policymakers and the public. It compiles, evaluates, comprehensively process and transparently communicate the latest findings from polar related climate research. The paper will present different aspects of this work.

  20. Outcomes of a science teacher development program for middle-level interdisciplinary teams: Relationships among teachers' beliefs, school contexts, and implementation

    NASA Astrophysics Data System (ADS)

    Olkin, Arlene H.

    Project Alliance, a teacher development program conducted by George Mason University and the American Association for the Advancement of Science with National Science Foundation funding (ESI-9355753) from 1994 to 1998, provided professional development for interdisciplinary teaching teams to enhance middle-level science instruction. Teachers experienced the same kinds of constructivist, hands-on, inquiry-based learning environments that they were expected to create for their students. The purposes of this study of 48 participants are (a) to assess the effectiveness of Project Alliance, and (b) to investigate relationships among teachers' beliefs about teaching and learning, school contexts, and individual teachers' implementation of the program's goals. Two cohorts of interdisciplinary teams from the mid-Atlantic region volunteered for two years each. During the first of two summer institutes, teachers engaged in graduate studies of environmental science, geology, technology, pedagogical content knowledge, and team teaching methods and designed integrated environmental science curriculum units to implement in their schools during the following academic year. Quantitative and qualitative methods were used to investigate individual teachers' implementation of the curriculum units. Data sources included surveys, videotaped presentations, interviews, focus groups, and classroom observations. Quantitative analyses employed exploratory correlation and regression procedures. Qualitative analyses followed a constant comparative process. Predictor variables were (1) teachers' personal epistemologies, measured by the Attitudes about Reality Scale; (2) certainty of practice, assessed with the Expert Science Teaching Evaluation Model, Teaching Practices Assessment Inventory; (3) school organizational structure; and (4) administrator involvement. Results showed that more than half of the teachers successfully implemented their units and all implemented unit-related activities. Both school organizational structure and the level of administrator involvement predicted an individual teacher's level of implementation, while personal epistemology and certainty of practice did not. Teachers' practice gradually became more constructivist and teaming increased their confidence in inquiry-based teaching. Project Alliance enhanced environmental science instruction in schools that supported teaming.

    Spatial visualization is an essential skill in the STEM disciplines, including the geosciences. Undergraduate students, including geoscience majors in upper-level courses, bring a wide range of spatial skill levels to the classroom. Students with weak spatial skills may be unable to understand fundamental concepts and to solve geological problems with a spatial component. However, spatial thinking skills are malleable. As a group of geoscience faculty members and cognitive psychologists, we have developed a set of curricular materials for Mineralogy, Sedimentology & Stratigraphy, and Structural Geology courses. These materials are designed to improve students' spatial skills, and in particular to improve students' abilities to reason about spatially complex 3D geological concepts and problems. Teaching spatial thinking in the context of discipline-based exercises has the potential to transform undergraduate STEM education by removing one significant barrier to success in the STEM disciplines. The curricular materials we have developed are based on several promising teaching strategies that have emerged from cognitive science research on spatial thinking. These strategies include predictive sketching, making visual comparisons, gesturing, and the use of analogy. We have conducted a three-year study of the efficacy of these materials in strengthening the spatial skills of students in upper-level geoscience courses at three universities. Our methodology relies on a pre- and post-test study design, with several tests of spatial thinking skills administered at the beginning and end of each semester. In 2011-2012, we used a "business as usual" approach to gather baseline data, measuring how much students' spatial thinking skills improved in response to the existing curricula. In the two subsequent years we have incorporated our new curricular materials, which can be found on the project website: http://serc.carleton.edu/spatialworkbook/activities.html Structural Geology students exposed to the new curricular materials are better able to solve some spatially challenging structural geological problems than students from the baseline year. We are continuing to analyze data from the Mineralogy and Sedimentology/Stratigraphy courses and will have completed the analysis by AGU.

  17. Queuing Models of Tertiary Storage

    Large scale scientific projects generate and use large amounts of data. For example, the NASA Earth Observation System Data and Information System (EOSDIS) project is expected to archive one petabyte per year of raw satellite data. This data is made automatically available for processing into higher level data products and for dissemination to the scientific community. Such large volumes of data can only be stored in robotic storage libraries (RSL's) for near-line access. A characteristic of RSL's is the use of a robot arm that transfers media between a storage rack and the read/write drives, thus multiplying the capacity of the system. The performance of the RSL's can be a critical limiting factor for the performance of the archive system. However, the many interacting components of an RSL make a performance analysis difficult. In addition, different RSL components can have widely varying performance characteristics. This paper describes our work to develop performance models of an RSL in isolation. Next we show how the RSL model can be incorporated into a queuing network model. We use the models to make some example performance studies of archive systems. The models described in this paper, developed for the NASA EODIS project, are implemented in C with a well defined interface.

  18. An investigation of communication patterns and strategies between international teaching assistants and undergraduate students in university-level science labs

    This research project investigates communication between international teaching assistants and their undergraduate students in university-level chemistry labs. During the fall semester, introductory-level chemistry lab sections of three experienced non-native speaking teaching assistants and their undergraduate students were observed. Digital audio and video recordings documented fifteen hours of lab communication, focusing on the activities and interactions in the first hour of the chemistry laboratory sessions. In follow-up one-on-one semi-structured interviews, the participants (undergraduates, teaching assistants, and faculty member) reviewed interactions and responded to a 10-item, 7-point Likert-scaled interview. Interactions were classified into success categories based on participants' opinions. Quantitative and qualitative data from the observations and interviews guided the analysis of the laboratory interactions, which examined patterns of conversational listening. Analysis of laboratory communication reveals that undergraduates initiated nearly two-thirds of laboratory communication, with three-fourths of interactions less than 30 seconds in duration. Issues of gender and topics of interaction activity were also explored. Interview data identified that successful undergraduate-teaching assistant communication in interactive science labs depends on teaching assistant listening comprehension skills to interpret and respond successfully to undergraduate questions. Successful communication in the chemistry lab depended on the coordination of visual and verbal sources of information. Teaching assistant responses that included explanations and elaborations were also seen as positive features in the communicative exchanges. Interaction analysis focusing on the listening comprehension demands placed on international teaching assistants revealed that undergraduate-initiated questions often employ deixis (exophoric reference), requiring teaching assistants to demonstrate skills at disambiguating undergraduate discourse. Interaction analysis reinforced that successful undergraduate-teaching assistant communication depends on the coordination of verbal and visual channels of communication, with the physical objects of the chemistry lab environment playing a pivotal role in expressing information and in mutual understanding. These results have implications for the evaluation of English proficiency and the preparation of non-native speaking teaching assistants by pointing out that teaching assistant listening comprehension skills and the use of contextual artifacts contribute to successful communication and are areas that, to date, have been underrepresented in the research literature on international teaching assistant communication.

    The Computational Science Education Project was initiated in September 1991, by the Department of Energy to develop a syllabus for teaching interdisciplinary computational science. CSEP has two major activities. The writing and maintenance of an electronic book (e-book) and educational outreach to the computational science communities through presentations at professional society meetings, journal articles, and by training educators. The interdisciplinary nature of the project is intended to contribute to national technological competitiveness by producing a body of graduates with the necessary skills to operate effectively in high performance computing environments. The educational outreach guides and supports instructors in developing computational science courses and curricula at their institutions. The CSEP e-book provides valuable teaching material around which educators have built. The outreach not only introduces new educators to CSEP, but also establishes a synergistic relationship between CSEP authors, reviewers and users.

  20. Describing students of the African Diaspora: Understanding micro and meso level science learning as gateways to standards based discourse

    In much of the educational literature, researchers make little distinction between African-American students and students of the African Diaspora who immigrated to the United States. Failing to describe these salient student differences serves to perpetuate an inaccurate view of African-American school life. In today's large cities, students of the African Diaspora are frequently learning science in settings that are devoid of the resources and tools to fully support their success. While much of the scholarship unites these disparate groups, this article details the distinctive learning culture created when students from several groups of the African Diaspora learn biology together in a Brooklyn Suspension Center. Specifically this work explains how one student, Gabriel, functions in a biology class. A self-described black-Panamanian, Gabriel had tacitly resigned to not learning science, which then, in effect, precluded him from any further associated courses of study in science, and may have excluded him from the possibility of a science related career. This ethnography follows Gabriel's science learning as he engaged in cogenerative dialogue with teachers to create aligned learning and teaching practices. During the 5 months of this research, Gabriel drew upon his unique lifeworld and the depth of his hybridized cultural identity to produce limited, but nonetheless important demonstrations of science. Coexistent with his involvement in cogenerative dialogue, Gabriel helped to construct many classroom practices that supported a dynamic learning environment which produced small yet concrete examples of standards based biology. This study supports further investigation by the science education community to consider ways that students' lifeworld experiences can serve to structure and transform the urban science classroom.
