Predictors of career commitment and employment level of tertiary-educated Indonesian women.  

PubMed

This study investigated the relationships among education, liberal sex-role values, gender-role orientation (masculinity/femininity), career commitment, and employment level for a sample of 302 married Indonesian women. All participants were tertiary educated and currently employed either as teachers in tertiary institutions or as managers in government or private enterprise. Multiple regression analysis revealed that liberal sex-role values and masculinity were significant predictors of career commitment, whereas education was the only variable to significantly predict employment level. Results are compared with previous research on predictors of career commitment and employment level in both Asian and Western cultures. Directions for further research are discussed. PMID:12349692

Issues of teaching science to nurses in the tertiary sector  

NASA Astrophysics Data System (ADS)

The shift of nurse education from the hospitals to higher education institutions has resulted in a large pool of students within the Universities requiring basic science instruction. Most of these students are female, often mature age, with limited science backgrounds. This paper discusses the type of science education demanded by the nursing profession, the view of science as a subject held by these students, and the key role played by constructivist thinking in dealing with both of these.

Customer satisfaction survey with clinical laboratory and phlebotomy services at a tertiary care unit level.  

PubMed

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.

Leprosy Scenario at a Tertiary Level Hospital in Delhi: A 5-year Retrospective Study  

PubMed Central

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 (?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

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

SciTech Connect

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.

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

PubMed Central

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 ± 87 US$ for spontaneous vaginal delivery and 168 ± 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

Self-Medication Practices with Antibiotics among Tertiary Level Students in Accra, Ghana: A Cross-Sectional Study  

PubMed Central

The study was carried out to estimate the prevalence of self-medication with antibiotics among tertiary level students in Accra (Ghana) and evaluate factors associated with the practice. This was a descriptive cross-sectional study and involved face-to-face interviews of 600 respondents selected by convenient sampling. Prevalence of self medication was 70% (95% CI: 66.3–73.7), and the practice was significantly lower among medically inclined students (OR: 0.2, 95% CI: 0.1–0.4, p < 0.001). Among the respondents who practiced self medication, the most common frequency of antibiotic usage was at intervals of one month (30%, 95% CI: 25.6–34.4%), and the most common antibiotic used was amoxacillin (23.9%, 95% CI: 21.0–26.8%). Treatment failure were reported by 35% (95% CI: 30.5–39.6%) of the respondents, and the main reasons cited for self medication were that, it was less expensive compared to medical care in the hospital and secondly, medical care in hospitals were associated with long delays. Forty nine percent (95% CI: 44.2–53.8%) of the respondents had poor knowledge about the health implications of irrational use of antibiotics, and 46% (95% CI: 41.2–50.8%) did not comply with the completion of the full course of antibiotics. Self medication among tertiary students in Accra is an important public health problem and this may reflect the situation among tertiary students in the whole of Ghana. PMID:23202760

Biostratigraphic, chronostratigraphic, and stratigraphic sequence analysis of Lower Tertiary marine sediments of Alabama for indicators of sea-level change  

SciTech Connect

Early Eocene to late Oligocene marine sedimentary units in southwestern Alabama were sampled at closely spaced intervals to derive a precise time-stratigraphic framework and to determine the paleoecological and mineralogical responses to fluctuations in sea level. Paleontologic control consisted of planktonic, smaller and larger benthonic foraminifera, calcareous nannofossils, dinoflagellates, and megafossils. Paleomagnetic reversals were delineated in two boreholes which, when supplemented by strontium isotope dates and the biostratigraphic control, provided a robust in situ chronostratigraphy for the Gulf Coast lower Tertiary. Paleoecologic trends in regression and transgression can be clearly correlated across major regional facies changes. Using the chronostratigraphy developed here, the second-, third-, and fourth-orders of Vail's global sea-level cycles can be recognized and demonstrate the influence of sea-level change on sedimentation. Stratigraphic systems tracts (SSTs) and bounding surfaces in outcrop were determined by lithologic variations and paleoecologic trends, and additionally by gamma logs in the cores. The lower sequence boundary occurs at a contact where an older, relatively fine-grained, deep-water, fossiliferous unit was abruptly succeeded by a coarse-grained, shallow-water, poorly fossiliferous unit. The transgressive surface occurs at the base of a fining- and deepening-upwards unit that was commonly glauconitic and very fossiliferous. Transgression culminated with a pulse of planktonic microfossils in a bed having reduced clastic sedimentation; on the log the surface of maximum starvation was marked by a gamma spike.

High-level and novel mechanisms of carbapenem resistance in Gram-negative bacteria from tertiary hospitals in Nigeria.  

PubMed

To determine the occurrence and molecular basis of carbapenem resistance in Gram-negative bacteria from tertiary hospitals in Nigeria, 182 non-duplicate Gram-negative bacterial isolates were investigated for antimicrobial susceptibility, presence of carbapenemases (tested phenotypically and genotypically), random amplified polymorphic DNA (RAPD) typing, plasmid sizing and replicon typing. Minimum inhibitory concentrations of carbapenems showed a high degree of resistance, with 67 isolates (36.8%) being resistant to all carbapenems, of which 40 (59.7%) produced enzymes able to hydrolyse imipenem. PCR and sequencing identified only 10 isolates (5.5%) carrying known carbapenemase genes, including bla(NDM), bla(VIM) and bla(GES). The majority of phenotypically carbapenem-resistant and carbapenemase-producing isolates did not carry a known carbapenemase gene. Transconjugant or transformant plasmid sizes were estimated to be 115 kb for bla(NDM)- and 93 kb for bla(VIM)-carrying plasmids. These plasmids were untypeable for replicon/incompatibility and transferred various other genes including plasmid-mediated quinolone resistance (PMQR) genes and bla(CTX-M-15). Typing showed that the isolates in this study were not clonally related. There is a high level of carbapenem resistance in Nigeria. As well as the globally relevant carbapenemases (bla(NDM), bla(VIM) and bla(GES)), there are other unknown gene(s) or variant(s) in circulation able to hydrolyse carbapenems and confer high-level resistance.

Level of Motivation Amongst Health Personnel Working in A Tertiary Care Government Hospital of New Delhi, India  

PubMed Central

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

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

NASA Astrophysics Data System (ADS)

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.

Efficacy of a multimodal intervention strategy in improving hand hygiene compliance in a tertiary level intensive care unit  

PubMed Central

Context: The role of hand hygiene in preventing health care associated infections (HCAIs) has been clearly established. However, compliance rates remain poor among health care personnel. Aims: a) To investigate the health care workers’ hand hygiene compliance rates in the intensive care unit (ICU), b) to assess reasons for non-compliance and c) to study the efficacy of a multimodal intervention strategy at improving compliance. Settings: A mixed medical–surgical ICU of a tertiary level hospital. Design: A before–after prospective, observational, intervention study. Materials and Methods: All health care personnel who came in contact with patients in the ICU were observed for their hand hygiene compliance before and after a multimodal intervention strategy (education, posters, verbal reminders and easy availability of products). A self-report questionnaire was also circulated to assess perceptions regarding compliance. Statistical analysis was done using ?2 test or Fisher exact test (Epi info software). Results: Hand hygiene compliance among medical personnel working in the ICU was 26% and the most common reason cited for non-compliance was lack of time (37%). The overall compliance improved significantly following the intervention to 57.36% (P<0.000). All health care worker groups showed significant improvements: staff nurses (21.48–61.59%, P<0.0000), nursing students (9.86–33.33%, P<0.0000), resident trainees (21.62–60.71%, P<0.0000), visiting consultants (22–57.14%, P=0.0001), physiotherapists (70–75.95%, P=0.413) and paramedical staff (10.71–55.45%, P< 0.0000). Conclusions: Hand hygiene compliance among health care workers in the ICU is poor; however, intervention strategies, such as the one used, can be useful in improving the compliance rates significantly.

Assessment and Evaluation: Middle Level Science  

NSDL National Science Digital Library

This reference for teachers describes the phases of the evaluation process, assessing student progress, student assessment in science, performance-based evaluation in science, record-keeping, program evaluation, and curriculum evaluation. It contains many "how-tos" for teachers. The reader is guided through the evaluation process phases, which include preparation, assessment, evaluation, and reflection. In the preparation stage, the teacher is given examples of what is good to evaluate. The assessment stage helps the evaluator to identify information-gathering strategies, construct or select instruments, administer them to the student, and collect information on student learning progress. In the evaluation phase, the information gathered is used to make judgements about student progress. And in the reflection phase, the evaluator decides what was or was not useful from the previous three phases. The document also has a chart detailing what types of evaluation methods are good for evaluating specific skills. For example, a portfolio is suggested for use in understanding a student's grasp of key concepts and science processes, as well as the student's values and attitudes. The sections on program and curriculum evaluation discuss how the Saskatchewan Board of Education is revamping its middle-level science program and lists what they will do and why they feel it will work to improve science education in that province.

Implementing a simplified neonatal resuscitation protocol-helping babies breathe at birth (HBB) - at a tertiary level hospital in Nepal for an increased perinatal survival  

PubMed Central

Background Reducing neonatal death has been an emerging challenge in low and middle income countries in the past decade. The development of the low cost interventions and their effective delivery are needed to reduce deaths from birth asphyxia. This study will assess the impact of a simplified neonatal resuscitation protocol provided by Helping Babies Breathe (HBB) at a tertiary hospital in Nepal. Perinatal outcomes and performance of skilled birth attendants on management of intrapartum-related neonatal hypoxia will be the main measurements. Methods/Design The study will be carried out at a tertiary level maternity hospital in Nepal. A prospective cohort-study will include a six-month baseline a six month intervention period and a three-month post intervention period. A quality improvement process cycle will introduce the neonatal resuscitation protocol. A surveillance system, including CCD cameras and pulse oximeters, will be set up to evaluate the intervention. Discussion Along with a technique to improve health workers performance on the protocol, the study will generate evidence on the research gap on the effectiveness of the simplified neonatal resuscitation protocol on intrapartum outcome and early neonatal survival. This will generate a global interest and inform policymaking in relation to delivery care in all income settings. Trial registration ISRCTN97846009 PMID:23039709

Data-driven quality improvement in the Emergency Department at a level one trauma and tertiary care hospital.  

PubMed

To demonstrate how a comprehensive and internally driven Continuous Quality Improvement (CQI) program was designed and implemented in our Emergency Department (ED) in 1999. This program involved monthly data collection and analysis, data-driven process change, staff education in the core concepts of quality, and data reanalysis. Data components collected during the program included census data, physician profiling, and focused clinical audits. CQI measures collected at the beginning of the program and quarterly included: (1) CQI metric data (turnaround times [TAT] and rates of left against medical advice [AMA] or left without being seen [LWOBS]), (2) rates and nature of patient complaints, and (3) results of patient satisfaction surveys performed by an outside consulting firm contracted by hospital administration. During the 4 years since its implementation the program demonstrated improvement in all measured areas. Despite an increase in patient volume of 32% to nearly 37,000 visits/year, and only minimal staffing adjustments, the mean quarterly TAT decreased from 183 min to 165 min (9.8% decrease), the rate of complaints dropped by 56.1% (2.1 per 1000 patients to 0.92), and patients leaving AMA or LWOBS decreased 66.7% from 2.7% to 0.9%. Overall, 44.8% of ED patients rated their care as "excellent." In summary, we demonstrate how a comprehensive quality improvement program was structured and implemented at a tertiary care center and how such a program demonstrated improvement in specific CQI parameters.

Prevalence of High and Low Level Mupirocin Resistance among Staphylococcal Isolates from Skin Infection in a Tertiary Care Hospital  

PubMed Central

Background: Mupirocin has been used for the treatment of skin infections and for the eradication of the nasal carriage of Methicillin -resistant Staphylococcus aureus (MRSA). The increased use of this antibiotic has been accompanied by its resistance, resulting in treatment failures. Objective: This study was aimed at determining the prevalences of low and high level Mupirocin resistance among the clinical isolates of Staphylococcus species which were obtained from pyogenic infections. Material and Method: Clinical samples such as wound swabs, tissues and pus which were submitted to the microbiology laboratory during a period of six months were screened for the growth of Staphylococcus species, which were identified as Staphylococcus aureus and Coagulase negative Staphylococcus species by the routine microbiological procedures. All the isolates were tested for their Mupirocin susceptibilities by using 5 and 200 ?g discs and their resistance was confirmed from their Minimum Inhibitory Concentrations (MICs). Result: Out of 400 samples, 150 samples grew Staphylococcus species, of which 113 were Staphylococcus aureus and 37 were Coagulase negative Staphylococcus (CoNS). Only 5(3.3%) mupirocin resistant Staphylococcus species: three high level and two low level strains were detected. The MICs for the two low level and three high level Mupirocin resistant strains were 256 mg/L and ?512mg/L each respectively. Conclusion: We conclude that the screening for mupirocin resistance, in terms of high-level and low-level resistance among the Staphylococcus species from patients with skin and soft tissue infections is warranted and that it is important for the clinicians in selecting the appropriate, empirical, topical, antimicrobial therapy. It also provides useful information about the prevalence of these resistant pathogens. PMID:23543635

Third trimester maternal plasma total fibronectin levels in pregnancy-induced hypertension: results of a tertiary center.  

PubMed

The aim of this study was to evaluate maternal plasma total fibronectin values in pregnancy-associated hypertension in women in the third trimester of pregnancy. A total of 125 pregnant women at the 24th week of gestation participated in this study. Nonpregnant normotensive women were included as control group (n = 30). Plasma samples for fibronectin were obtained at the 24th, 28th, and 32nd weeks of gestation from all pregnant patients. From this cohort, 10 patients met the criteria for the diagnosis of gestational hypertension and 15 women met the stringent requirements of preeclampsia, whereas 100 patients were normotensive later in gestation. Plasma total fibronectin levels were determined by radial immunodiffusion technique. Data were analyzed using the SPSS program. The mean plasma fibronectin levels of the pregnant women in whom gestational hypertension and preeclampsia developed were significantly higher at the 24th, 28th, and 32nd weeks in comparison to normotensive pregnant women (p < 0.001). However, throughout the period from the 24th to 32nd weeks of pregnancy, plasma total fibronectin levels did not exhibit a significant change in normotensive pregnant patients or in patients with preeclampsia and gestational hypertension. There was also no correlation between plasma fibronectin levels and gestational age, mean arterial pressure, birth weight, and 5-minute Apgar scores in all groups (p < 0.05). The elevated maternal plasma fibronectin level over 40 mg/dL is capable of predicting preeclampsia with a sensitivity of 73% and a specificity of 92%. These results suggest that serial plasma fibronectin measurements before 24 weeks' of gestation may be helpful in the early detection of preeclampsia in normotensive gravid women who are destined to become clinically preeclamptic.

Determinants of symptom profile and severity of conduct disorder in a tertiary level pediatric care set up: A pilot study  

PubMed Central

Background: Conduct disorders (CDs) are one of the most common causes for referral to child and adolescent mental health centers. CD varies in its environmental factors, symptom profile, severity, co-morbidity, and functional impairment. Aims: The aim was to analyze the determinants of symptom profile and severity among childhood and adolescent onset CD. Settings and Design: Clinic based study with 60 consecutive children between 6 and 18 years of age satisfying International Classification of Disease-10 Development Control Rules guidelines for CD, attending behavioral pediatrics unit outpatient. Materials and Methods: The family psychopathology, symptom severity, and functional level were assessed using parent interview schedule, revised behavioral problem checklist and Children's Global Assessment Scale. Statistical Analysis: The correlation and predictive power of the variables were analyzed using SPSS 16.0 version. Results: There was significant male dominance (88.3%) with boy girl ratio 7.5:1. Most common comorbidity noticed was hyperkinetic disorders (45%). Childhood onset group was more predominant (70%). Prevalence of comorbidity was more among early onset group (66.7%) than the late-onset group (33.3%). The family psychopathology, symptom severity, and the functional impairment were significantly higher in the childhood onset group. Conclusion: The determinants of symptom profile and severity are early onset (childhood onset CD), nature, and quantity of family psychopathology, prevalence, and type of comorbidity and nature of symptom profile itself. The family psychopathology is positively correlated with the symptom severity and negatively correlated with the functional level of the children with CD. The symptom severity was negatively correlated with the functional level of the child with CD. PMID:25568472

Predictors of student success in entry-level science courses  

NASA Astrophysics Data System (ADS)

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.

West Hackberry Tertiary Project  

SciTech Connect

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 I Program for the development of advance recovery technologies in fluvial dominated deltaic reservoirs. The goal of the West Hackberry Tertiary Project is to demonstrate the technical and economic feasibility of combining air injection with the Double Displacement Process for tertiary oil recovery. The concept is being field tested in low pressure (350 to 800 pounds per square inch (psi)) reservoirs on the north flank of the field and high pressure reservoirs (2500 to 3300 psi) on the west flank of the field.

Investigation of Inquiry-based Science Pedagogy among Middle Level Science Teachers: A Qualitative Study  

NASA Astrophysics Data System (ADS)

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 concep

High Satisfaction Rating by Users of Private-for-profit Healthcare Providers—evidence from a Cross-sectional Survey Among Inpatients of a Private Tertiary Level Hospital of North India  

PubMed Central

Background: Evaluation of outcomes can help improve the quality of provision of services within a healthcare setting. There is limited report on patient satisfaction in private-sector in India although they provide three-quarters of healthcare services. Aim: The study was designed to report the level of satisfaction among inpatients of a private tertiary care hospital in India. Materials and Methods: A total of 102 participants were recruited and their socio-demographic, health-seeking behavior, and satisfaction rating on various aspects of healthcare were elicited. A five item Likert scale was used to obtain the satisfaction rating. Data analysis was done with the help of Stata version-9. Proportions for the discrete variables and means with Standard Deviation for the continuous variables were obtained. Results: All the participants were urban and from upper-middle or upper socio-economic strata. The participants reported a high level of overall satisfaction (93%) as well as high satisfaction with physicians (95%), the doctor's interpersonal skills (99%), nursing-care (93%), general services (94%), and pharmacy (88.1%). Conclusion: There was a high level of satisfaction reported by the participants at this tertiary level hospital. This might reflect the actual good quality services being provided by the provider or the nonannoying response, which cannot be ruled out. PMID:23050252

Human health screening level risk assessments of tertiary-butyl acetate (TBAC): calculated acute and chronic reference concentration (RfC) and Hazard Quotient (HQ) values based on toxicity and exposure scenario evaluations.  

PubMed

A screening level risk assessment has been performed for tertiary-butyl acetate (TBAC) examining its primary uses as a solvent in industrial and consumer products. Hazard quotients (HQ) were developed by merging TBAC animal toxicity and dose-response data with population-level, occupational and consumer exposure scenarios. TBAC has a low order of toxicity following subchronic inhalation exposure, and neurobehavioral changes (hyperactivity) in mice observed immediately after termination of exposure were used as conservative endpoints for derivation of acute and chronic reference concentration (RfC) values. TBAC is not genotoxic but has not been tested for carcinogenicity. However, TBAC is unlikely to be a human carcinogen in that its non-genotoxic metabolic surrogates tertiary-butanol (TBA) and methyl tertiary butyl ether (MTBE) produce only male rat ?-2u-globulin-mediated kidney cancer and high-dose specific mouse thyroid tumors, both of which have little qualitative or quantitative relevance to humans. Benchmark dose (BMD)-modeling of the neurobehavioral responses yielded acute and chronic RfC values of 1.5 ppm and 0.3 ppm, respectively. After conservative modeling of general population and near-source occupational and consumer product exposure scenarios, almost all HQs were substantially less than 1. HQs exceeding 1 were limited to consumer use of automotive products and paints in a poorly ventilated garage-sized room (HQ = 313) and occupational exposures in small and large brake shops using no personal protective equipment or ventilation controls (HQs = 3.4-126.6). The screening level risk assessments confirm low human health concerns with most uses of TBAC and indicate that further data-informed refinements can address problematic health/exposure scenarios. The assessments also illustrate how tier-based risk assessments using read-across toxicity information to metabolic surrogates reduce the need for comprehensive animal testing. PMID:25629921

Advancing the Science of Community-Level Interventions  

PubMed Central

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.

American Tertiary mollusks of the genus Clementia  

USGS Publications Warehouse

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. Stewart, of the University of California, read the manuscript, and I have taken advantage of his suggestions. I am also indebted to Mr. L. R. Cox, of the British Museum, for information relating to the fossil species from Persia, Zanzibar, and Burma, and to Dr. Axel A. Olsson, of the International Petroleum Co., for data concerning undescribed Tertiary species from Peru.

Tertiary gain and disability syndromes.  

PubMed

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.

Tertiary Vegetation History  

E-print Network

The Tertiary period, from 2.5 to 65 million years ago, was the time of origin of the modern Sierra Nevada landscape. Climates, geology, and vegetation changed drastically in the Sierra Nevada during this time, and analyses of this period provide both context for and insight into vegetation dynamics of the current and future Sierra. During the early Tertiary, warm-humid, subtropical to tropical conditions prevailed on the low, rolling plains of the area now the Sierra Nevada. Fossil taxa with tropical adaptations and affiliations were widespread throughout the region. In the Sierra Nevada, ginkgo (Ginkgo biloba), avocado (Persea), cinnamon (Cinnamomum), fig (Ficus), and tree fern (Zamia) were common. At the end of the Eocene epoch, about 34 million years ago, global climates changed rapidly from warmequable to cool-seasonal temperate conditions. In response, vegetation also shifted enormously; cool-dry-adapted conifers and

Ethiopian Tertiary dike swarms  

NASA Technical Reports Server (NTRS)

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.

Science self-efficacy of African Americans enrolled in freshman level physical science courses in two historically black institutions  

NASA Astrophysics Data System (ADS)

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.

Organizational health and the achievement level of students in science at the secondary-level schools in Sri Lanka  

NASA Astrophysics Data System (ADS)

This study sought to identify those organizational health factors that might have overriding influence on the achievement level of students in science in Sri Lankan secondary schools. This study involved 752 students, 33 science teachers, and 10 principals from two different districts, Ampara and Colombo, in Sri Lanka. Ten Tamil medium, secondary level, public schools were selected to participate in this study. Data were collected using four types of instruments: a questionnaire for pupils; interview schedules for science teachers and principals; checklists for classroom/school facilities, science laboratory facilities, and science practicals; and a science achievement test. The analysis focused on the collective perceptions of students, science teachers, and principals. Regression and path analyses were used as major analysis techniques, and the qualitative data provided by science teachers and principals were considered for a crosschecking of the quantitative inferences. The researcher found teacher affiliation, academic emphasis, and instructional leadership of the principal, in descending order, were the overriding influential factors on the achievement level of students in science in Sri Lankan secondary schools. At the same time a similar descending order was found in their mean values and qualities. The researcher concluded that increasing the quality of the organizational health factors in Sri Lankan secondary schools would result in improved better achievement in science. The findings further indicate that instructional leadership of the principal had both direct and indirect effects on students' achievement in science when academic emphasis and teacher affiliation were taken into account. In addition, the resource support of the principal did not make any difference in students' science achievement and the findings stress the availability of the resources for individual students instead of assuming the general facilities of the school are available to all students of the school.

Tertiary serpentinite tectonics in northern Hispaniola  

SciTech Connect

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.

Apolipoproteins AI/B/E gene polymorphism and their plasma levels in patients with coronary artery disease in a tertiary care-center of Eastern India  

PubMed Central

Aim The present study was designed to investigate whether the three-apolipoprotein (AI, B, E) gene polymorphisms were related to alter their plasma protein levels and hence associated to coronary artery disease (CAD). Methods We determined distribution of MspI apo AI, EcoRI apo B, HhaI apo E gene polymorphisms, plasma apolipoproteins and lipids levels among 150 patients having CAD admitted to the Department of Cardiology, N.R.S. Medical College & Hospital, Kolkata, India during June 2010–June 2012 and 150 age sex matched healthy controls. Results We found that ApoAI concentration of studied population was significantly different in each genotypes of ?75 G/A apo AI (p < 0.0001) gene polymorphism. A significant association was found in multivariate analysis for the genotypes with apo E4 allele [odds ratio (OR): 3.639; 95% confidence interval (CI): 1.019–12.995, p = 0.040] with four conventional risk factors (i.e. smoking, low-density lipoprotein, ApoAI and ApoB) with CAD. In contrast E2 allele has reverse effect, but the genotypes with apo E2 allele was no longer significant in the multivariate model (OR: 1.788; 95% CI: 0.400–8.001, p = 0.447) where as being significant in univariate analysis (OR: 0.219; 95% CI: 0.087–0.552, p = 0.001). Conclusions Our findings suggest that the polymorphisms apo AI MspI and apo B EcoRI do not seem to affect CAD. But the genotype with E4 allele of apo E gene independent of other risk factors is associated with this disease. PMID:24407534

Effective science teachers' professional development: A multiple-case study of district-level science supervisors' perspectives  

NASA Astrophysics Data System (ADS)

At its heart, science teachers' professional development is about continual growth and improvement (Yager, 2005). Conducting research to understand what constitutes effective professional development is inherently complex (Hewson, 2007). The imperative to link research on professional development to student achievement (Fishman, Marx, Best, & Tal, 2003) increases complexity of research on the topic. These complexities require multiple research approaches and indicate that all stakeholders could provide insights to identify what constitutes effective professional development. District-level science supervisors' voices are missing from the data on effective science teachers' professional development and this provides a potential gap in the literature (Banilower, Heck, & Weiss, 2007; Elmore & Burney, 1999; Shroyer, Miller, Hernandez, & Dunn, 2007). The purpose of this multiple-case study was to gather information from six district-level science supervisors from six different school districts in six different states to gain a deeper understanding of their insights on what constitutes effective professional development. The empirical data examined in this study resulted from interviews, participant drawings, observations, and document review. The major finding was that the district-level science supervisors mostly confirmed what was known in the field. However, this finding could be used in a variety of ways to support future research; such as providing a potential data source to corroborate self-reported teacher survey data. The findings from this study also identified a few nuances to what is known about effective science teachers' professional development research. Specifically, a finding suggests that researchers may need to reconceptualize the amount of time before which science teachers' professional development can impact student achievement. Another nuance identified relates to the, already known, understanding that district-level science supervisors' beliefs (Borman, 2005) and position power can impact their actions (Spillane, 2000). This nuance suggests that district-level science supervisors may desire that the teachers in their districts teach as they taught. If so, future research should identify what teaching approaches the district-level science supervisors utilized when they were teaching.

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

NASA Astrophysics Data System (ADS)

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.

Communicating Ocean Science at the Lower-Division Level  

NASA Astrophysics Data System (ADS)

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.

Analysis and classification of RNA tertiary structures  

PubMed Central

There is a fast growing interest in noncoding RNA transcripts. These transcripts are not translated into proteins, but play essential roles in many cellular and pathological processes. Recent efforts toward comprehension of their function has led to a substantial increase in both the number and the size of solved RNA structures. With the aim of addressing questions relating to RNA structural diversity, we examined RNA conservation at three structural levels: primary, secondary, and tertiary structure. Additionally, we developed an automated method for classifying RNA structures based on spatial (three-dimensional [3D]) similarity. Applying the method to all solved RNA structures resulted in a classified database of RNA tertiary structures (DARTS). DARTS embodies 1333 solved RNA structures classified into 94 clusters. The classification is hierarchical, reflecting the structural relationship between and within clusters. We also developed an application for searching DARTS with a new structure. The search is fast and its performance was successfully tested on all solved RNA structures since the creation of DARTS. A user-friendly interface for both the database and the search application is available online. We show intracluster and intercluster similarities in DARTS and demonstrate the usefulness of the search application. The analysis reveals the current structural repertoire of RNA and exposes common global folds and local tertiary motifs. Further study of these conserved substructures may suggest possible RNA domains and building blocks. This should be beneficial for structure prediction and for gaining insights into structure–function relationships. PMID:18824509

State Restrictions on Methyl Tertiary Butyl Ether (released in AEO2006)  

EIA Publications

By the end of 2005, 25 states had barred, or passed laws banning, any more than trace levels of methyl tertiary butyl ether (MTBE) in their gasoline supplies, and legislation to ban MTBE was pending in 4 others. Some state laws address only MTBE; others also address ethers such as ethyl tertiary butyl ether (ETBE) and tertiary amyl methyl ether (TAME). Annual Energy Outlook 2006 assumes that all state MTBE bans prohibit the use of all ethers for gasoline blending.

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  

NASA Astrophysics Data System (ADS)

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.

The levels of edit. [technical writing in science  

NASA Technical Reports Server (NTRS)

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.

Tertiary ice sheet dynamics: The snow gun hypothesis  

SciTech Connect

The authors abserve strong negative correlation between Tertiary low- to mid-latitude planktonic foraminiferal {delta}{sup 18}O and the difference between these data and coeval benthic foraminiferal {delta}{sup 18}O. Late Quaternary data do not show this correlation. Coupling statistical model/{delta}{sup 18}O comparisons and evidence for Antarctic ice and ocean temperature variation, they infer that Tertiary ice volume, recorded by tropical planktonic {delta}{sup 18}O became lost in the noise. This renders low correlation between Teritiary planktonic and benthic {delta}{sup 18}O time series compared to late Quaternary data. They contend that Tertiary ice sheet growth was commonly driven by warming of deep water from low- to mid-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, they infer ice volume fluctuations to be an important component of sea level history on timescales between 10{sup 3} and 10{sup 7} years.

Optical sensing systems for primary-level science education  

NASA Astrophysics Data System (ADS)

In the last three years, a number of Irish primary schools have been using LEGO Mindstorms technology in order to investigate the use of project-based learning as an alternative teaching tool. This has involved the use of LEGO bricks combined with standard electronic motors and some commercial sensors (e.g. temperature). In order to develop this project into the area of science education, we have developed a range of miniaturized optical sensors, which are compatible with the LEGO platform. This paper describes two such sensors that have been developed and fabricated for use with the LEGO platform, a collaboration between the MIT Media Lab and the National Centre for Sensor Research. In particular a working oxygen sensor has been designed and fabricated. The principal design features were compatibility with the programmable LEGO platforms and robustness for classroom use. This sensor uses the method of intensity quenching to determine oxygen concentration. In addition, simple color sensors have been produced. The aim of developing such sensors is to familiarize students with the concept of colour detection and to introduce them to the basic principles of spectroscopy. The performance of both sensor types and preliminary classroom results are reported.

Evolution of Tertiary Mammals of North America  

NASA Astrophysics Data System (ADS)

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.

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

NASA Astrophysics Data System (ADS)

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.

Endosymbiotic Gene Transfer in Tertiary Plastid-Containing Dinoflagellates  

PubMed Central

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.

Linguistic Resources Used in Grade 8 Students' Submicro Level Explanations—Science Items from TIMSS 2007  

NASA Astrophysics Data System (ADS)

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.

Classroom-Based Science Research at the Introductory Level: Changes in Career Choices and Attitude  

PubMed Central

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 undergraduates’ 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.

Multiple-Choice Exams: An Obstacle for Higher-Level Thinking in Introductory Science Classes  

PubMed Central

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

Mid Tertiary palynostratigraphy of Thailand  

NASA Astrophysics Data System (ADS)

Mid Tertiary palynological assemblages from fourteen stratigraphic sequences in nine basins in Thailand have been investigated. Special emphasis has been given to the spore-pollen record and its stratigraphic distribution. The basis for defining the zonations is the first or last appearance of key species including: Inaperturopollenites dubius, Alnipollenites verus and Echiperiporites cf. E. estelae. For the first time, correlation between terrestrial and dated marine sequences is achieved. Two palynological zones (SIAM-1 and SIAM-2) have been constructed. SIAM-I Zone is characterized by, inter alia, assemblages comprising high frequencies of gymnospermous pollen, and is provisionally correlated with the planktonic foraminiferal N3-N4 zones of the Trang-1 Borehole, Andaman Sea, indicating an Upper Oligocene to early Lower Miocene age. SIAM-2 Zone is characterized by influxes of tropical taxa and decreasing proportions of the temperate taxa and is provisionally correlated with planktonic foraminiferal N5-N8 zones of the Mergui-1 Borehole, Andaman Sea, indicating a middle to later Lower Miocene age. The results show that the Nong Ya Plong Basin coal seam (pre SIAM-1) is older than the Li Basin coal seams (SIAM-1), Fang Basin oil-bearing intervals (SIAM-2) and Mae Moh Basin coal seams (post SIAM-2).

Computational Prediction of RNA Tertiary Structure  

NASA Astrophysics Data System (ADS)

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.

Latitudinal gradients in tertiary molluscan faunas of the Pacific coast  

USGS Publications Warehouse

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.

Review of evidence for late Tertiary shorelines occurring on South Atlantic coasts  

NASA Astrophysics Data System (ADS)

Recognition of (late) Tertiary shorelines on continental coasts is becoming increasingly common. It is argued that the elevations of such features are central to their approximate dating and the demonstration of contemporaneity with similar features elsewhere. South Atlantic coasts have not had a long history of investigation, yet there exist many diffuse observations, in both time and space, which are here drawn together into a preliminary synthesis and the case for widespread occurrences of late Tertiary shorelines in the region reviewed. This allows comparison with other areas from which Tertiary shorelines are known, the Atlantic seaboards of the Southeastern United States and Northwest Europe, for example. The coasts of oceanic islands are probably the best places to examine the legacy of late Cenozoic sea-level changes. It is suggested that, since many of the cliffed shores of these islands appear to be the result of a rapid emergence, coastal features predating this event might be preserved on the cliff-tops. Possible late Tertiary shorelines from South Atlantic islands are described, as are those which have been positively dated to this period, in the Eastern Canary Islands, for instance. Sedimentary and morphological indicators of Tertiary high sea-levels are described from Antarctic coasts. South American and African Atlantic continental margins. Evidence from the latter two areas is most suspect, owing to their generally more complex Quaternary tectonic histories. A summary of the evidence for Tertiary shorelines on South Atlantic coasts is tabulated. Methods which have been or could be used to date late Tertiary shorelines are described. Minimum age can be deduced from that of deposits resting on an erosional surface, maximum age from that of the youngest formation across which a surface is cut. More precise age can be estimated where a marine surface is sandwiched between datable non-marine formations or where periods of tectonic activity (responsible for differential surface deformation) can be dated. Elevations of surfaces can be used to estimate ages. Problems in both recognising and dating Tertiary shorelines are discussed. Recognition of their origin is made more difficult by their degraded state and, if they occur within a Quaternary erosional sequence, their antiquity may not be realised. It is suggested that fluctuations in the Antarctic ice sheet during the late Tertiary induced substantial glacio-eustatic changes of sea-level which may have been most marked in adjacent areas. This is considered to be the mechanism through which late Tertiary shorelines in the area were formed yet, considering the paucity of the morphological and sedimentary data, these should not be used as the basis for a eustatic chronology.

Topological constraints are major determinants of tRNA tertiary structure and dynamics and provide basis for tertiary folding cooperativity.  

PubMed

Recent studies have shown that basic steric and connectivity constraints encoded at the secondary structure level are key determinants of 3D structure and dynamics in simple two-way RNA junctions. However, the role of these topological constraints in higher order RNA junctions remains poorly understood. Here, we use a specialized coarse-grained molecular dynamics model to directly probe the thermodynamic contributions of topological constraints in defining the 3D architecture and dynamics of transfer RNA (tRNA). Topological constraints alone restrict tRNA's allowed conformational space by over an order of magnitude and strongly discriminate against formation of non-native tertiary contacts, providing a sequence independent source of folding specificity. Topological constraints also give rise to long-range correlations between the relative orientation of tRNA's helices, which in turn provides a mechanism for encoding thermodynamic cooperativity between distinct tertiary interactions. These aspects of topological constraints make it such that only several tertiary interactions are needed to confine tRNA to its native global structure and specify functionally important 3D dynamics. We further show that topological constraints are conserved across tRNA's different naturally occurring secondary structures. Taken together, our results emphasize the central role of secondary-structure-encoded topological constraints in defining RNA 3D structure, dynamics and folding. PMID:25217593

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

NASA Astrophysics Data System (ADS)

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.

The study describes the experience of introducing three intensity levels of parent participation in three third-grade classes for science instruction using Playtime is Science; an equity curriculum that utilizes parent participation. The study sought to determine the optimum level of participation by ascertaining the most influential aspect of involvement on proficiency scores and the most important aspect of involvement to participants. The levels of participation intensity were distinguished by: (1) the number of parents in the classroom; (2) the responsibilities of the parents; (3) the training received; and (4) the number of students with whom the parents worked. Involvement at each level would potentially manifest aspects of role modeling, lowered student-to-adult instructional ratio, and parent expertise to varying degrees. The three levels of participation were introduced during explorations in three Playtime is Science units following a rotation schedule. Student proficiency was assessed through scores on pre- and post-tests, journals, and discourse. ANCOVA was used to identify main and interaction effects of the independent variables (class, unit and level) on student proficiency taking into account existing differences in groups. Participant attitudes were assessed through journals and interviews. Observations of explorations triangulated findings and assessed participant interactions. Field notes, transcripts and photographs were coded according to the aspects of parent involvement. The results showed level of parent intensity of involvement had no affect on proficiency scores. Therefore, no aspect of parent involvement was determined to be the most influential. Participants felt that lowered instructional ratio and role modeling were the most important aspects of involvement. The level of involvement that utilized the lowest ratio and the most role modeling was level III, small group facilitators. Level III was recognized as the optimum level of participation in science instruction for this study. Although no level of involvement was significantly influential for student scores, there was a main effect for units, supporting the finding that teacher conceptions of science are more influential on student proficiency than parent participation at any level. The influence of teacher conceptions was unanticipated but is critical to consider when implementing any program or methodology to improve science instruction.

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

NASA Astrophysics Data System (ADS)

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.

Job Stress, Satisfaction, and Coping Strategies Among Medical Interns in a South Indian Tertiary Hospital  

PubMed Central

Background: It has previously been demonstrated that there is a significant drop in all domains of quality of life among interns during internship. Aims: A modified version of the health consultant's job stress and satisfaction questionnaire (HCJSSQ) was used to assess and quantify aspects of internship that were perceived as stressful and satisfying. Methods used to cope with work place stress were explored. Settings and Design: A prospective cohort study was undertaken among 93 medical interns doing a rotating internship at the Christian Medical College and Hospital, a tertiary-care hospital in southern India. Materials and Methods: After completion of 6 months of internship, the modified version of the HCJSSQ was administered to all participants. Statistical Analysis: The data were entered into Statistical Package for the Social Sciences (SPSS) Version 9 by double data entry technique. Percentages of interns reporting high levels of stress, satisfaction were calculated. Results: While 63.4% of interns reported high levels of satisfaction, 45.2% of the interns experienced high levels of stress, 17.6% coped with work stress by using alcohol and nicotine, and 37% coped through unhealthy eating habits. Conclusion: More people found internship satisfying than stressful. However, a high proportion found it stressful, and many reported unhealthy coping mechanisms. PMID:25035558

Science Teachers' Proficiency Levels and Patterns of TPACK in a Practical Context  

NASA Astrophysics Data System (ADS)

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.

Achievement motivation level in students of Shiraz University of Medical Sciences and its influential factors  

PubMed Central

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

Cooperative Tertiary Interaction Network Guides RNA Folding  

SciTech Connect

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.

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

NASA Astrophysics Data System (ADS)

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.

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

NASA Astrophysics Data System (ADS)

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.

Archival Legacy Investigation of Circumstellar Environments (ALICE). Candidates point sources and high-level science products  

NASA Astrophysics Data System (ADS)

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.

In-class examinations in college-level science: New theory, new practice  

NASA Astrophysics Data System (ADS)

Every faculty member knows that exams drive student behavior. Testing and grading are part of every course, but generally of lesser importance to faculty members than course content itself. Recently, instructional methods and pedagogy. But as issues of grade inflation, student attrition, accountability, and authentic assessment grow in importance, we see some interesting innovations in testing methods and some interesting innovations. The authors are publishing a collection of some of these as described in their own words, by faculty themselves. Two questions underlie the study: 1) why is it so difficult to change tests and testing traditions in college-level science and 2) will the enormous efforts underway to reform pedagogy and curriculum in these disciplines have any lasting effect if testing does not have a prominent place on the reform agenda?

A Model for Teaching a Climate Change Elective Science Course at the Community College Level  

NASA Astrophysics Data System (ADS)

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.

Early Tertiary climates of the Arctic Ocean  

SciTech Connect

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.

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  

NASA Astrophysics Data System (ADS)

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.

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

USGS Publications Warehouse

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.

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

PubMed Central

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

Conformation analysis and computation of energy barrier to rotation about Csbnd N bond in para-methylphenyl carbamate and its solvent dependence in comparison with tertiary carbamates and tertiary amides  

NASA Astrophysics Data System (ADS)

Barrier to rotation about conjugated Csbnd N bond in p-Methyl phenyl carbamate (PMPC) was computed 14-16 kcal/mol at three levels of HF, B3LYP and MP2 using 6-311++G?? basis set. The solvent effect and energy barriers about Csbnd N bond in PMPC were compared to the case of tertiary carbamates and tertiary amides. Moreover, it is shown that in primary carbamates such as PMPC and tertiary amides isomerisation process passes through TS2 and TS1 respectively, while in tertiary carbamates goes through a combination of both TSs. Furthermore, X-ray analysis which is reported for the first time for primary aryl carbamates demonstrated that the inclusive plane of carbamate functional group is perpendicular to the plane of phenyl ring. The results of computations are completely in agreement with the X-ray data.

Beyond The Prime Directive: The MAST Discovery Portal and High Level Science Products  

NASA Astrophysics Data System (ADS)

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.

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

NASA Astrophysics Data System (ADS)

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.)

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)

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).

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

NASA Astrophysics Data System (ADS)

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.

Queuing Models of Tertiary Storage  

NASA Technical Reports Server (NTRS)

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.

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

NASA Astrophysics Data System (ADS)

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.

An analysis of integrated science and language arts themes in software at the elementary school level  

NASA Astrophysics Data System (ADS)

There are many demands on the elementary classroom teacher today, such that teachers often do not have the time and resources to instruct in a meaningful manner that would produce effective, real instruction. Subjects are often disjointed and not significant. When teachers instruct using an integrated approach, students learn more efficiently as they see connections in the subjects. Science and language arts, when combined to produce an integrated approach, show positive associations that can enable students to learn real-life connections. In addition, with the onset of technology and the increased usage of technological programs in the schools, teachers can use technology to support an integrated curriculum. When teachers use a combined instructional focus of science, language arts, and technology to produce lessons, students are able to gain knowledge of concepts and skills necessary for appropriate academic growth and development. Given that there are many software programs available to teachers for classroom use, it is imperative that quality software is used for instruction. Using criteria based upon an intensive literature review of integrated instruction in the areas of science and language arts, this study examines science and language arts software programs to determine whether there are science and language arts integrated themes in the software analyzed. Also, this study examines whether more science and language arts integrated themes are present in science or language arts software programs. Overall, this study finds a significant difference between language arts software and science software when looking at integrated themes. This study shows that science software shows integrated themes with language arts more often than does language arts software with science. The findings in this study can serve as a reference point for educators when selecting software that is meaningful and effective in the elementary classroom. Based on this study, it is apparent that there is a need to evaluate software for appropriate use in the classroom in order to promote effective education.

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

NASA Astrophysics Data System (ADS)

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

Peer-driven contraceptive choices and preferences for contraceptive methods among students of tertiary educational institutions in Enugu, Nigeria  

PubMed Central

Purpose To describe the methods preferred for contraception, evaluate preferences and adherence to modern contraceptive methods, and determine the factors associated with contraceptive choices among tertiary students in South East Nigeria. Methods A questionnaire-based cross-sectional study of sexual habits, knowledge of contraceptive methods, and patterns of contraceptive choices among a pooled sample of unmarried students from the three largest tertiary educational institutions in Enugu city, Nigeria was done. Statistical analysis involved descriptive and inferential statistics at the 95% level of confidence. Results A total of 313 unmarried students were studied (194 males; 119 females). Their mean age was 22.5±5.1 years. Over 98% of males and 85% of females made their contraceptive choices based on information from peers. Preferences for contraceptive methods among female students were 49.2% for traditional methods of contraception, 28% for modern methods, 10% for nonpharmacological agents, and 8% for off-label drugs. Adherence to modern contraceptives among female students was 35%. Among male students, the preference for the male condom was 45.2% and the adherence to condom use was 21.7%. Multivariate analysis showed that receiving information from health personnel/media/workshops (odds ratio 9.54, 95% confidence interval 3.5–26.3), health science-related course of study (odds ratio 3.5, 95% confidence interval 1.3–9.6), and previous sexual exposure prior to university admission (odds ratio 3.48, 95% confidence interval 1.5–8.0) all increased the likelihood of adherence to modern contraceptive methods. Conclusion An overwhelming reliance on peers for contraceptive information in the context of poor knowledge of modern methods of contraception among young people could have contributed to the low preferences and adherence to modern contraceptive methods among students in tertiary educational institutions. Programs to reduce risky sexual behavior among these students may need to focus on increasing the content and adequacy of contraceptive information held by people through regular health worker-led, on-campus workshops.

Methyl tertiary hexyl ether and methyl tertiary octyl ether as gasoline oxygenates: assessing risks from atmospheric dispersion and deposition.  

PubMed

Methyl tertiary hexyl ether (MtHxE) and methyl tertiary octyl ether (MtOcE) are currently being developed as replacement oxygenates for methyl tertiary butyl ether (MtBE) in gasoline. As was the case with MtBE, the introduction of these ethers into fuel supplies guarantees their introduction into the environment as well. In this study, a screening-level risk assessment was performed by comparing predicted environmental concentrations (PEC) of these ethers to concentrations that might cause adverse effects to humans or ecosystems. A simple box model that has successfully estimated urban air concentrations of MtBE was adapted to predict atmospheric concentrations of MtHxE and MtOcE. Expected atmospheric concentrations of these ethers were also estimated using the European Union System for the Evaluation of Substances (EUSES) multimedia fate model, which simultaneously calculates PECs in the various environmental compartments of air, water, soil, and sediment. Because little or no data are available on the physicochemical, environmental, and toxicological properties of MtHxE and MtOcE, estimation methods were used in conjunction with EUSES to predict both the PECs and the concentrations at which these ethers might pose a threat. The results suggest that these ethers would contaminate the air of a moderately sized U.S. city (Boston, MA) at levels similar to those found previously for MtBE. The risk assessment module in EUSES predicted risk characterization ratios of 10(-3) and 10(-2) for MtHxE and MtOcE, respectively, in Boston, and 10(-2) and 10(-1) in very large urban centers, suggesting that these ethers pose only a minimal threat to ecosystems at the anticipated environmental concentrations. The assessment also indicates that these compounds are possible human carcinogens and that they may be present in urban air at concentrations that pose an unacceptable cancer risk. Therefore, testing of the toxicological properties of these compounds is recommended before they replace MtBE in gasoline. PMID:17063870

Levels of use of an elementary school inquiry-based instructional innovation among a selected group of teacher participants in the Delaware Elementary Science Initiative  

NASA Astrophysics Data System (ADS)

Science education in Delaware's public elementary and middle schools has experienced much change in recent years as a result of the adoption of state standards and, in particular, the adoption by school districts of the Smithsonian/National Science Resources Council-sponsored inquiry-based instruction modules as part of the "Elementary Science Initiative." As part of this adoption process, each participating elementary teacher and middle school science teacher receives extensive training in the use of several discrete science kits. The trainings include reinforcement and development of content knowledge, in addition to the modeling of and practice with complementary pedagogy. One measure of the effectiveness of the science kit training process (and perhaps the Initiative itself) is the teachers' levels of use of the Initiative. The purpose of this study was to determine the participating teachers' use of the science kit innovation through the use of the Concerns-based Adoption Model Levels of Use Questionnaire. Eight K--5 elementary classroom teachers who had completed at least three science kit trainings participated. The results of this study indicate that on the Overall Level of Use Rating Scale, teachers who had completed training in at least three science kits generally scored at the Routine (IVA) level. All of the teachers, regardless of the wide range in the number of years of experience, had achieved the Mechanical Use level in Overall (III) LoU, and 6 of the 8 participants (75%) were operating at no less than the Refinement (IVA) Overall LoU level.

Lymphatic vessels and tertiary lymphoid organs  

PubMed Central

Tertiary lymphoid organs (TLOs) are accumulations of lymphoid cells in chronic inflammation that resemble LNs in their cellular content and organization, high endothelial venules, and lymphatic vessels (LVs). Although acute inflammation can result in defective LVs, TLO LVs appear to function normally in that they drain fluid and transport cells that respond to chemokines and sphingosine-1-phosphate (S1P) gradients. Molecular regulation of TLO LVs differs from lymphangiogenesis in ontogeny with a dependence on cytokines and hematopoietic cells. Ongoing work to elucidate the function and molecular regulation of LVs in TLOs is providing insight into therapies for conditions as diverse as lymphedema, autoimmunity, and cancer. PMID:24590281

Disaster resilience in tertiary hospitals: a cross-sectional survey in Shandong Province, China  

PubMed Central

Background Hospital disaster resilience can be defined as a hospital’s ability to resist, absorb, and respond to the shock of disasters while maintaining critical functions, and then to recover to its original state or adapt to a new one. This study aims to explore the status of resilience among tertiary hospitals in Shandong Province, China. Methods A stratified random sample (n =?50) was derived from tertiary A, tertiary B, and tertiary C hospitals in Shandong Province, and was surveyed by questionnaire. Data on hospital characteristics and 8 key domains of hospital resilience were collected and analysed. Variables were binary, and analysed using descriptive statistics such as frequencies. Results A response rate of 82% (n =?41) was attained. Factor analysis identified four key factors from eight domains which appear to reflect the overall level of disaster resilience. These were hospital safety, disaster management mechanisms, disaster resources and disaster medical care capability. The survey demonstrated that in regard to hospital safety, 93% had syndromic surveillance systems for infectious diseases and 68% had evaluated their safety standards. In regard to disaster management mechanisms, all had general plans, while only 20% had specific plans for individual hazards. 49% had a public communication protocol and 43.9% attended the local coordination meetings. In regard to disaster resources, 75.6% and 87.5% stockpiled emergency drugs and materials respectively, while less than a third (30%) had a signed Memorandum of Understanding with other hospitals to share these resources. Finally in regard to medical care, 66% could dispatch an on-site medical rescue team, but only 5% had a ‘portable hospital’ function and 36.6% and 12% of the hospitals could surge their beds and staff capacity respectively. The average beds surge capacity within 1 day was 13%. Conclusions This study validated the broad utility of a framework for understanding and measuring the level of hospital resilience. The survey demonstrated considerable variability in disaster resilience arrangements of tertiary hospitals in Shandong province, and the difference between tertiary A hospitals and tertiary B hospitals was also identified in essential areas.

Osmium Isotopic Composition of the Sumbar Cretaceous- Tertiary Boundary, Turkmenia  

NASA Astrophysics Data System (ADS)

Turekian (1982) propagated the use of the osmium isotopic composition as a cosmic indicator for the origin of the high osmium (and iridium) layers at the K/T boundaries. He did not consider the osmium isotopic signature of the terrestrial mantle, which also has a chondritic evolution of the Re-Os system. Osmium cannot serve alone as an infallible indicator of the impact theory, but interesting results can be obtained from their investigation. Different K/T boundary section have been analyzed so far for ^187Os/^186Os. An overview of the values is presented in the table. Boundary Clay layer Os ratio Reference Stevns Klint fish clay 1.66 Luck and Turekian, 1983 Woodside Creek 1.12 Lichte et al., 1986 Raton Basin 1.23 Kraehenbuehl et al., 1988 Raton Basin (several) 1.15-1.23 Esser and Turekian, 1989 Sumbar (0-1 cm) 1.16 This work We obtained a complete marine section of the K/T boundary in southern Turkmenia (decribed by Alekseyev, 1988). It shows a very high Ir concentration (66 ppb) at the boundary layer and a remarkable Ir enrichment over crustal rocks continuing up to 30 cm above the boundary. Our aim of this investigation is to analyze several samples from above and below the boundary for the ^187Os/^186Os ratio to obtain a complete picture of the isotopic evolution of the section. We want to evaluate mixing of Os with chondritic ratios with Os from upper crustal rocks. Another goal is to investigate a mobilization of Os. So far only one sample has been analyzed with NTI-MS after fire assay digestion of the sample. The sample 0 to 1 cm has an ^187Os/^186Os ratio of 1.162 +- 13, which is quite low. We expect an even lower value for the boundary clay (0 cm) itself not taking into account a contribution of radiogenic osmium from the decay of terrestrial rhenium. This might put this K/T boundary section closest of all to the present day chondritic value (approx. 1.05). Further analysis will be presented at the meeting. References Alekseyev A. S., Nazarov M.

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

NASA Astrophysics Data System (ADS)

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 background—background that is necessary for understanding the processes involved in volcanic eruptions. Second, many non-science students have built-in anxieties with respect to math and science, anxieties that must be considered when designing curriculum and syllabi. It is essential to provide the right balance of technical information while remaining in touch with the audience. My approach to the class involves a dynamic lecture format that incorporates a wide array of multimedia, analogue demonstrations of volcanic processes, and small-group discussions of topics and concepts. In addition to teaching about volcanoes—a fascinating subject in and of itself—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.

High Level Community Perspective of VxOs and Their Science Expectations (Invited)  

NASA Astrophysics Data System (ADS)

In recent years NASA has initiated a program to develop a set of Virtual Observatories (VxOs, where the “x” represents a discipline, such as the Virtual Magnetospheric Observatory, or VMO). From a high level perspective the VxOs fulfill an important, if not essential, role in fulfilling NASA’s open data policy. VxOs are envisaged as being portals for access to many different types and sources of data, thereby removing the need for an individual to access separate data sources, with different query and data transfer mechanisms. New missions are expected to develop Project Data Management Plans that adhere to NASA’s open data policy, and the VxOs are clearly a mechanism to ensure that data are disseminated to as large a community as possible. That being said, there are some concerns. First, a mission cannot rely on a VxO being present, as a VxO’s existence depends on programmatic decisions separate from mission-specific programmatic decisions. Second, since early in a mission, much of the expertise needed to interpret the data resides within the mission science team, the VxO may not have enough resources to disseminate the necessary knowledge. Independent scientists may consequently find themselves using the primary mission data source, rather than going through the VxO. This leads to a secondary concern with VxOs, which is the need for extensive metadata to characterize and catalog the data. Early in a mission, while all parties may have the best of intentions, there will in all likelihood be insufficient time and resources to develop the necessary metadata for the VxOs. This can be partially mitigated through the adoption of an incremental approach to metadata development for the VxO. But, since many of the properties of the mission, its instruments, and the data they provide will not be fully understood until well into the mission, it is likely that VxOs will have greatest utility for mature missions. One last aspect of VxOs comes from the user perspective. It is important that VxOs make extensive use of “beta testers.” What is important for a VxO is not that it have a clever interface, but that it provide quick access to datasets by constructing the appropriate queries, and that it is flexible enough to handle both large and small data requests.

Eustatic control of tertiary hydrocarbon deposits, Central California borderline basins  

SciTech Connect

In the central California borderland basins, the Vail-Haq Cenozoic Global Eustatic Cycle appears to have influenced depositional patterns that have fundamental significance in the present distribution of hydrocarbon source and reservoir beds. Coupled with tectonic events, traps were created that now control the distribution of hydrocarbon accumulations. Seismic data combined with subsurface lithostratigraphic, biostratigraphic, and log data from wells drilled on the central California outer continental shelf (OCS) were used to date and correlate Tertiary stratigraphic sequences in the Santa Maria, Bodega-La Honda, and Point Arena basins. Benthic foraminiferal assemblages also served to reconstruct each basin's paleobathymetric history. The west coast benthic foram stages, commerically used to solve subsurface stratigraphic problems for over 60 yr, occur with planktonic microfossil groups that now serve to calibrate the provincial stages with the absolute geologic time scale. The Miocene through Pliocene stratigraphic sequences in these three depocenters are markedly similar, and record a parallel marine onlap and offlap pattern that correlates closely with the Vail-Haq Cenozoic Global Eustatic Cycle. The highstand depositional cycles are generally dominated by organic-rich sediments of good to excellent are generally dominated by organic-rich sediments of good to excellent source-bed potential. Lowstand regressive to transgressive clastic deposits have good reservoir potential. The middle Miocene siliceous Monterey Formation was deposited during maximum Tertiary global sea levels and is present in all of these basins. In addition to being a prolific source bed, the Monterey is unique in that when diagnetically altered, it fractures and also becomes an excellent hydrocarbon reservoir.

Addressing the Access Problem for Patients with Serious Mental Illness who Require Tertiary Medical Care.  

PubMed

There is evidence to suggest that people with serious mental illness (SMI) have lower access to tertiary care than patients without SMI, particularly when care is complex. Barriers are present at the level of the individual, providers, and the health care system. High levels of co-morbidity and the associated health care costs, along with a growing focus on facilitating equal access to quality care for all, urges health care systems to address existing gaps. Some interventions have been successful at improving access to primary care for patients with SMI, but relatively little research has focused on access to complex interventions. This paper summarizes the scope of the problem regarding access to complex tertiary medical care among people with SMI. Barriers are discussed and potential solutions are proposed. Policies and programs must be developed, implemented, and evaluated to determine cost-effectiveness and impact on outcomes. PMID:25702725

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

NASA Astrophysics Data System (ADS)

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.

Tracking emergency department overcrowding in a tertiary care academic institution.  

PubMed

Despite the release of a national report describing key markers of emergency department (ED) overcrowding, limited linear data using these markers have been published. We sought to report the degree and trends of ED overcrowding in a typical academic hospital and to highlight some of the key markers of ED patient flow and care. We conducted a prospective study in a large Canadian urban tertiary care teaching hospital that receives approximately 55,000 annual adult ED visits. A database captured demographic and real-time process of care data for each patient from 2000 to 2007. Descriptive data are reported using Canadian Triage and Acuity Scale (CTAS) scores. Over the study period, the ED patient visit volume and presentation times remained predictable. Emergent cases (CTAS levels 1-2) doubled from 8 to 16.6%, and urgent cases (CTAS level 3) increased from 40.2 to 50.3%. Moreover, semi-urgent presentations (CTAS level 4) decreased from 42.4 to 28.8%, and non-urgent cases (CTAS level 5) dropped from 9.4 to 4.3%. The median wait time from triage to bed location increased from two minutes (inter-quartile range [IQR] 1, 46) in 2000 to 27 minutes (IQR 2, 110) in 2007, while the median time from bed location to physician remained constant (29 minutes in 2001 versus 28 minutes in 2007). Overall, admissions increased from 20.4 to 23%. Semi-urgent and non-urgent admissions dropped from 11.5 to 7.4% and 3.2 to 1.8%, respectively. Admitted patients "boarding" in the ED increased from 70,955 hours in 2002 to 118,741 hours in 2007, while the number of emergent and urgent patients leaving without being seen increased by more than 400%. ED overcrowding in a tertiary care hospital is primarily a result of access block due to boarding admitted patients, a situation that poses serious risks to the majority of patients who have emergent or urgent conditions that cannot be managed appropriately in the waiting room.

A Model for Cretaceous and Tertiary Extension of the Ross Sea, Antarctica.  

NASA Astrophysics Data System (ADS)

The timing and magnitude of Ross Sea extension has remained largely problematic. Outstanding questions include, did Tertiary extension of the Victoria Land Basin (VLB) affect the Central and Eastern Basins, why is there so much Oligocene RSS-2 in the Ross Sea basins, and what accounts for the necessary accommodation space? We computed a 1-D backstripped subsidence model for the Central Trough and Eastern Basin to infer periods of extension. Unit thicknesses were obtained from interpreted MCS depth sections in the deepest part of the basins for the analysis. Stratigraphic units were decompacted and tectonic subsidence calculated. Estimated corrections for paleobathymetry and eustatic sea level changes were applied. Our results support two extensional episodes throughout the Ross Sea, a Cretaceous episode and an early Tertiary episode. Cretaceous extension occurred at a stretching factor of ~2 and Tertiary extension occurred at ~1.5 to 2 in the Central Trough and portions of the Eastern Basin at this time. Tertiary stretching factors in the VLB were 2 to 3. All extension was completed by the first deposition of RSS-2 above unconformity RSU6 (~30 Ma). If Oligocene strata were deposited during extension, syn-rift characteristics are expected. However, these strata are not faulted or deformed in the central and eastern Ross Sea. Tertiary extension was likely simultaneous with seafloor spreading along the Eocene Adare Trough (43-26 Ma) northwest of the Ross Sea. Approximately 180 km of east-west extension due to this spreading could have extended Ross Sea basins. The VLB is 130 to 150 km wide, requiring that remaining Adare Trough extension is accommodated elsewhere, possibly in the Central Trough and the Eastern Basin. An alternative model with only Cretaceous extension east of the VLB, limiting Tertiary extension only to the VLB [Karner et al, 2005 EPSL], requires that most thermal subsidence throughout the Ross Sea predates Oligocene sedimentation. This timing requires that Oligocene unconformity RSU6 formed many of hundreds of meters below sea level, implying that RSU6 is not a wave-cut feature and that other processes, such as glaciation or sea level changes, formed the unconformity. We intend to expand our 1-D model into a 2-D model and apply decompaction corrections and subsidence calculations to a grid of the Ross Sea in order to determine how all the basins respond in 2-D.

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

NASA Astrophysics Data System (ADS)

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.

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

NASA Astrophysics Data System (ADS)

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.

Tertiary Excess of Fibroblast Growth Factor 23 and Hypophosphatemia Following Kidney Transplantation  

PubMed Central

Hypophosphatemia due to inappropriate urinary phosphate wasting is a frequent metabolic complication of the early period following kidney transplantation. Although previously considered to be caused by tertiary hyperparathyroidism, recent evidence suggests a primary role for persistently elevated circulating levels of the phosphorus-regulating hormone, fibroblast growth factors 23 (FGF23). In the setting of a healthy renal allograft, markedly increased FGF23 levels from the dialysis period induce renal phosphate wasting and inhibition of calcitriol production, which contribute to hypophosphatemia. While such tertiary FGF23 excess and resultant hypophosphatemia typically abates within the first few weeks to months post-transplant, some recipients manifest persistent renal phosphate wasting. Furthermore, increased FGF23 levels have been associated with increased risk of kidney disease progression, cardiovascular disease and death outside of the transplant setting. Whether tertiary FGF23 excess is associated with adverse transplant outcomes is unknown. In this article, we review the physiology of FGF23, summarize its relationship with hypophosphatemia after kidney transplantation, and speculate on its potential impact on long term outcomes of renal allograft recipients.

Molecular epidemiology of vancomycin-resistant enterococci isolated from non-tertiary-care and tertiary-care hospitals in Korea.  

PubMed

This study compared the molecular characteristics of vancomycin-resistant Enterococcus faecium (VREF) isolates recovered from 20 non-tertiary-care hospitals (36 isolates) and three tertiary-care hospitals (26 isolates) in diverse geographical areas of Korea from October 2010 to April 2011. All isolates carried the vanA gene only, but 42% and 73% of non-tertiary and tertiary-care isolates expressed the VanB phenotype (teicoplanin minimum inhibitory concentration ?16 ?g/ml). All isolates harboured insertion sequences, IS1542 and IS1216V, within Tn1546. The isolates from tertiary-care hospitals tended to have reduced Tn1546 lengths by deletion of sequences adjacent to IS elements. Multilocus sequence typing revealed eight sequence types within clonal complex 17 (CC17), but DNA fingerprinting by rep-PCR did not show clonal relatedness between the intra- and inter-hospital isolates. These results suggest that vanA, which has prevailed in tertiary-care hospitals of Korea since the 1990s, had been transferred horizontally to non-tertiary-care hospitals while the genetic rearrangement driven by evolutionary adaptation to adverse environments may have occurred in tertiary-care hospitals.

Grignard Synthesis of Various Tertiary Alcohols  

NASA Astrophysics Data System (ADS)

A general Grignard procedure is presented for the synthesis of aliphatic, tertiary alcohols containing six to nine carbons. Without revealing the specific starting materials, students are challenged to identify their unknown products from physical (boiling points, refractive indices) and spectral (infrared O-H, C-H and fingerprint regions) data. Once a product is identified retro-synthetic considerations point to which alkyl halide and ketone were required as starting materials. This laboratory exercise in organic synthesis incorporates anhydrous techniques, distillation, and infrared analysis. RX + Mg ---> [RMgX] + R'R"C=O ---> [RR'R"COMgX] ---> RR'R"COH Criteria RX = C2-C5 1' alkyl bromide (unbranched) R'R"C=O = C3-C5 ketone RR'R"COH = C6-C9 3' alcohol

'Tertiary' nuclear burning - Neutron star deflagration?  

NASA Technical Reports Server (NTRS)

A motivation is presented for the idea that dense nuclear matter can burn to a new class of stable particles. One of several possibilities is an 'octet' particle which is the 16 baryon extension of alpha particle, but now composed of a pair of each of the two nucleons, (3Sigma, Delta, and 2Xi). Such 'tertiary' nuclear burning (here 'primary' is H-He and 'secondary' is He-Fe) may lead to neutron star explosions rather than collapse to a black hole, analogous to some Type I supernovae models wherein accreting white dwarfs are pushed over the Chandrasekhar mass limit but explode rather than collapse to form neutron stars. Such explosions could possibly give gamma-ray bursts and power quasars, with efficient particle acceleration in the resultant relativistic shocks. The new stable particles themselves could possibly be the sought-after weakly interacting, massive particles (WIMPs) or 'dark' matter.

Methyl Tertiary Butyl Ether (MTBE) Groundwater Contamination  

NSDL National Science Digital Library

Methyl tertiary-butyl ether (MTBE), a fuel additive, is highly mobile in groundwater, dissolving and traveling faster than the other petroleum constituents which tend to biodegrade and adsorb to soil particles. This unit will introduce the problem of pollutants as they move through the various soil layers and contaminate the groundwater and challenge the students to investigate the effects of MTBE spills in the environment by researching the available literature on fuel oxygenates and learning their mode of transport through the soil. Experimentally determined data, obtained in lab activities, will facilitate building models of the contamination process of the groundwater. Mathematics modeling will involve the use of spreadsheet analysis of real-world-data obtained online.

Aqueous flooding methods for tertiary oil recovery  

DOEpatents

A method of aqueous flooding of subterranean oil bearing formation for tertiary oil recovery involves injecting through a well into the formation a low alkaline pH aqueous sodium bicarbonate flooding solution. The flooding solution's pH ranges from about 8.25 to 9.25 and comprises from 0.25 to 5 weight percent and preferably about 0.75 to 3.0 weight percent of sodium bicarbonate and includes a petroleum recovery surfactant of 0.05 to 1.0 weight percent and between 1 and 20 weight percent of sodium chloride. After flooding, an oil and water mixture is withdrawn from the well and the oil is separated from the oil and water mixture.

SciTech Connect

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.

One of the characteristics of most breast tumors is that regions can become starved for oxygen. This condition, known as hypoxia, is associated with an increased risk that the tumor will spread beyond the breast and eventually lead to death. New research results from the Johns Hopkins Physical Sciences-Oncology Center (PS-OC) has now identified key molecular events triggered by hypoxia and demonstrated how they might enable breast tumor cells to metastasize.

Graduate student involvement with designing inquiry-based Earth science field projects for the secondary-level classroom  

NASA Astrophysics Data System (ADS)

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.

Challenges associated with the management of gynecological cancers in a tertiary hospital in South East Nigeria  

PubMed Central

Background There are reports of increasing incidence of gynecological cancers in developing countries and this trend increases the need for more attention to gynecological cancer care in these countries. Objective The purpose of this study was to describe the presentation and treatment of gynecological cancers and identify barriers to successful gynecological cancer treatment in a tertiary hospital in South East Nigeria. Methods This study was a retrospective longitudinal analysis of the presentation and treatment of histologically diagnosed primary gynecological cancers from 2000 to 2010. Analysis was by descriptive and inferential statistics at the 95% level of confidence using Statistical Package for the Social Sciences version 17 software. Results Records of 200 gynecological cancers managed during the study period were analyzed. Over 94% of cervical cancers presented in advanced stages of the disease and received palliative/symptomatic treatment. Only 1.9% of cervical cancer patients had radical surgical intervention, and postoperative mortality from these radical surgeries was 100%. Approximately 76% of patients with ovarian cancer had debulking surgery as the mainstay of treatment followed by adjuvant chemotherapy. Postoperative mortality from ovarian cancer surgery was 63%. Cutting edge cytotoxic drugs were not used as chemotherapy for ovarian and chorionic cancers. Compliance with chemotherapy was poor, with over 70% of ovarian cancer patients failing to complete the prescribed courses of chemotherapy. Most patients with endometrial and vulval cancers had only surgical treatment, as compliance with follow-up for adjuvant chemotherapy or radiotherapy was poor. Functional radiotherapy facilities were not available at the center during the study period, thereby necessitating external referrals to centers hundreds of kilometers away. Conclusion Late presentation of cases, noncompliance with treatment regimens, lack of use of cutting edge cytotoxic drugs, the poor outcome of radical surgeries, and lack of a functional radiotherapy facility combined to create a very difficult gynecological cancer care environment at the study center.

Wildfires and animal extinctions at the Cretaceous/Tertiary boundary  

NASA Astrophysics Data System (ADS)

Persuasive models of the ejection of material at high velocities from the Chicxulub asteroid impact marking the Cretaceous/Tertiary boundary have led to the conclusion that upon return, that material, heated in passage through the upper atmosphere, generated a high level of infrared energy density over the Earth's surface. That radiant energy has been considered to be a direct source of universal wildfires, which were presumed to be a major cause of plant and animal species extinctions. The extinction of many animal species, especially the dinosaurs, has also been attributed to the immediate lethal effects of the radiation. I find that the absorption of the radiation by the atmosphere, by cloud formations, and by ejecta drifting in the lower atmosphere reduced the radiation at the surface to a level that cannot be expected to have generated universal fires. Although the reduced radiation will have likely caused severe injuries to many animals, such insults alone seem unlikely to have generated the overall species extinctions that have been deduced.

Unheard voices: outcomes of tertiary care for treatment-refractory psychosis  

PubMed Central

Aims and method In up to a quarter of patients, schizophrenia is resistant to standard treatments. We undertook a naturalistic study of 153 patients treated in the tertiary referral in-patient unit of the National Psychosis Service based at the Maudsley Hospital in London. A retrospective analysis of symptoms on admission and discharge was undertaken using the OPCRIT tool, along with preliminary economic modelling of potential costs related to changes in accommodation. Results In-patient treatment demonstrated statistically significant improvements in all symptom categories in patients already identified as having schizophrenia refractory to standard secondary care. The preliminary cost analysis showed net savings to referring authorities due to changes from pre- to post-discharge accommodation. Clinical implications Despite the enormous clinical, personal and societal burden of refractory psychotic illnesses, there is insufficient information on the outcomes of specialised tertiary-level care. Our pilot data support its utility in all domains measured. PMID:25237502

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

NASA Astrophysics Data System (ADS)

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.

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

NASA Astrophysics Data System (ADS)

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.)

Master's level graduate training in medical physics at the University of Colorado Health Sciences Center  

NASA Astrophysics Data System (ADS)

Medical physics is an applied branch of physics which is concerned with the application of energy in various forms to the diagnosis and treatment of disease. It is allied closely with medical electronics, bioengineering, and health physics, but extends beyond the boundaries of these rather specific disciplines. The diversity of medical physics demands a broad background of both coursework and experience for persons working in this field. To provide such training, educational programs have been developed such as the Master's degree program in medical physics of the University of Colorado Health Sciences Center. The program at the University of Colorado was established in 1971 and is noteworthy for its emphasis on the practical and clinical aspects of medical physics.

Prediction of protein tertiary structures using MUFOLD  

PubMed Central

There have been steady improvements in protein structure prediction during the past two decades. However, current methods are still far from consistently predicting structural models accurately with computing power accessible to common users. To address this challenge, we developed MUFOLD, a hybrid method of using whole and partial template information along with new computational techniques for protein tertiary structure prediction. MUFOLD covers both template-based and ab initio predictions using the same framework and aims to achieve high accuracy and fast computing. Two major novel contributions of MUFOLD are graph-based model generation and molecular dynamics ranking (MDR). By formulating prediction as a graph realization problem, we apply an efficient optimization approach of Multidimensional Scaling (MDS) to speed up the prediction dramatically. In addition, under this framework, we enhance the predictions consistently by iteratively using the information from generated models. MDR, in contrast to widely used static scoring functions, exploits dynamics properties of structures to evaluate their qualities, which can often identify best structures from a pool more effectively.

Tertiary tectonic in the Tehuantepec Isthmus, Mexico  

SciTech Connect

A microplate model in the basement was proposed according to photointerpretation of satellite imagery and supported with microtectonic studies in the Tehuantepec's Isthmus. The microplate is located in the northwestern part of the [open quotes]Sierra de Chiapas,[close quotes] and structurally has lineaments that correspond with sinestral wrench faults oriented northeast-southwest and dextral faults oriented northwest-southeast. In the front of the microplate, these faults are joined in an arc form. The microplate began its movement forward to the north in the middle Tertiary. This movement originated in a regional compressional stress that was younger to the north. The stress changed the orientation of the anticline axis from northwest-southeast to west-east. In its western limit, the stress produces a sinestral shear stress that built a rotational deformation in the [open quotes]Sierra Atravesada,[close quotes] and represents a superimposed tectonic block over an ancient (laramide) orogeny. This system has also produced other secondary transtensional effects oriented northwest-southeast, represented along the [open quotes]Depression Central del Istmo.[close quotes] The microplate has formed a tensional system opening the [open quotes]Superior, Inferior, and Mar Muerto[close quotes] lagoons. The microplate is strongly related with the relief, seismic activity, and the tectonics of the salt of the Tehuantepec's Isthmus.

Genome Evolution of a Tertiary Dinoflagellate Plastid  

PubMed Central

The dinoflagellates have repeatedly replaced their ancestral peridinin-plastid by plastids derived from a variety of algal lineages ranging from green algae to diatoms. Here, we have characterized the genome of a dinoflagellate plastid of tertiary origin in order to understand the evolutionary processes that have shaped the organelle since it was acquired as a symbiont cell. To address this, the genome of the haptophyte-derived plastid in Karlodinium veneficum was analyzed by Sanger sequencing of library clones and 454 pyrosequencing of plastid enriched DNA fractions. The sequences were assembled into a single contig of 143 kb, encoding 70 proteins, 3 rRNAs and a nearly full set of tRNAs. Comparative genomics revealed massive rearrangements and gene losses compared to the haptophyte plastid; only a small fraction of the gene clusters usually found in haptophytes as well as other types of plastids are present in K. veneficum. Despite the reduced number of genes, the K. veneficum plastid genome has retained a large size due to expanded intergenic regions. Some of the plastid genes are highly diverged and may be pseudogenes or subject to RNA editing. Gene losses and rearrangements are also features of the genomes of the peridinin-containing plastids, apicomplexa and Chromera, suggesting that the evolutionary processes that once shaped these plastids have occurred at multiple independent occasions over the history of the Alveolata.

Epidemiologic study of ankle fractures in a tertiary hospital  

PubMed Central

OBJECTIVES: To evaluate the epidemiology of ankle fractures surgically treated at the Instituto de Ortopedia e Traumatologia do Hospital das Clínicas da Universidade de São Paulo. METHODS: Medical records of patients admitted with foot and ankle fractures between 2006 and 2011 were revised. Seventy three ankle fractures that underwent surgical treatment were identified. The parameters analyzed included age, gender, injured side, AO and Gustilo & Anderson classification, associated injuries, exposure, need to urgent treatment, time to definitive treatment and early post-operative complications. Study design: retrospective epidemiological study. RESULTS: Male gender was predominant among subjects and the mean age was 27.5 years old. Thirty nine fractures resulted from traffic accidents and type B fracture according to AO classification was the most common. Twenty one were open fractures and 22 patients had associated injuries. The average time to definitive treatment was 6.5 days. Early post-operative complications were found in 21.3% of patients. CONCLUSIONS: Ankle fractures treated in a tertiary hospital of a large city in Brazil affect young people victims of high-energy accidents and present significant rates of associated injuries and post-operative complications.

Diagenesis of Middle Tertiary carbonates in the Toa Baja Well, Puerto Rico  

NASA Astrophysics Data System (ADS)

The Toa Baja Well drilled in northern Puerto Rico to adepth of 2705 m (8872 ft.) penetrated over 550 m (1800 ft.) of Tertiary carbonates. The limestone-dominated portion of the well consists mostly of shallow-water backreef carbonates. Metastable carbonates have been either calcitized, dolomitized or dissolved. The pétrographie character of the Tertiary carbonates in the Toa Baja Well, and those reported by Monroe [1980], the cathodoluminescence petrography, and the stable isotopic compositions indicate that these carbonates were rapidly cemented in the marine environment (limiting compaction), that replacement of metastable carbonates by calcite and precipitation of sparry calcite took place mostly in meteoric diagenetic environments and dolomitization probably occurred in a meteoric-marine mixing zone. Given the history of numerous drainage systems that dissected the Tertiary carbonates throughout their depositional history [Monroe, 1980] and the repeated Cenozoic sea level oscillations [Monroe, 1980; Seiglie and Moussa, 1984], it is likely that alteration of metastable carbonates took place during lowstands. Interstratified fluvial deposits suggest the continued influence of meteoric fluids in local highlands [Monroe, 198O].

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

NASA Astrophysics Data System (ADS)

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.

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

NASA Astrophysics Data System (ADS)

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

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

PubMed Central

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.

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)

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.

LSST telescope primary/tertiary mirror hardpoints  

NASA Astrophysics Data System (ADS)

The Large Synoptic Survey Telescope (LSST) utilizes an 8.4-meter cast borosilicate primary/tertiary mirror (M1M3). This mirror system has stringent vibration and stiffness requirements because the LSST optical system does not include a fast steering mirror and the mission requires a short slew and settling time. The position stability of the M1M3 relative to the mirror cell is controlled by six displacement controlled actuators (subsequently referred to as "hardpoints") that form a large hexapod. This design is based largely on previous hardpoints implemented for borosilicate mirror positioning. Traditionally, all dynamic forces applied to these mirrors are reacted through their hardpoints. Consequently, the characteristics of these hardpoints critically affect the ability of the telescope to meet the stringent dynamic requirements without overstressing the mirror. The hardpoints must have a high stiffness of 120 N/um in the axial direction, while protecting the mirror by limiting the loads in all six degrees of freedom. The non-axial direction loads are limited by flexures. The axial loads are limited by a pneumatic breakaway mechanism. Since the hardpoints react the dynamic mirror loads, the axial breakaway force may limit the telescope's slewing accelerations. The travel of the breakaway mechanism must accommodate the transfer of the mirror from its active supports to its static supports. The hardpoint positioning mechanism must have sufficient travel and resolution to properly position the mirror relative to the mirror cell. Fulfilling these functions also requires numerous sensors, including a precision axial load cell which is paramount in determining the figure control actuator forces.

Use of tactual materials on the achievement of content specific vocabulary and terminology acquisition within an intermediate level science curriculum  

NASA Astrophysics Data System (ADS)

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.

A point-prevalence study at a tertiary Australian hospital found 199 of 462 inpatients (43%) to be receiving antibiotic therapy. Forty-seven per cent of antibiotic use was discordant with guidelines or microbiological results and hence considered inappropriate. Risk factors for inappropriate antibiotic prescribing included bone/joint infections, the absence of infection, creatinine level >120 µmol/L, carbapenem or macrolide use and being under the care of the aged care/rehabilitation team. In the setting of finite antimicrobial stewardship resources, identification of local determinants for inappropriate antibiotic use may enable more targeted interventions. PMID:22697156

The equity imperative in tertiary education: Promoting fairness and efficiency  

NASA Astrophysics Data System (ADS)

While the share of the tertiary education age cohort (19-25) which is being given the opportunity to study has increased worldwide over the past two decades, this does not in fact translate into reduced inequality. For many young people, especially in the developing world, major obstacles such as disparities in terms of gender, minority population membership or disabilities as well as academic and financial barriers are still standing in their way. The authors of this article propose a conceptual framework to analyse equity issues in tertiary education and document the scope, significance and consequences of disparities in tertiary education opportunities. They throw some light on the main determinants of these inequalities and offer suggestions about effective equity promotion policies directed towards widening participation and improving the chances of success of underprivileged youths in order to create societies which uphold humanistic values.

Emergency peripartum hysterectomy in a tertiary hospital in southern Nigeria  

PubMed Central

Introduction Emergency peripartum hysterectomy, a maker of severe maternal morbidity and near miss mortality is an inevitable surgical intervention to save a woman's life when uncontrollable obstetric haemorrhage complicates delivery. This study was conducted in order to determine the incidence, types, indications and maternal complications of emergency peripartum hysterectomy at the University of Uyo Teaching Hospital, Uyo, Nigeria. Methods The case records of all women who underwent emergency peripartum hysterectomy between 1st January 2004 and 31st December 2011 were studied. Results There were 12,298 deliveries during the study period and 28 emergency peripartum hysterectomies were performed resulting in a rate of 0.2% or 1 in 439 deliveries. The modal age group of the patients was 26-30 years (35.7%), majority were of low parity (64.4%), while 17.9% attained tertiary level education. Half of the patients (50.0%) were unbooked while 14.3% were antenatal clinic defaulters. Extensive uterine rupture (67.8%) was the most common indication for emergency hysterectomy distantly followed by uterine atony with uncontrollable haemorrhage (17.9%). Subtotal abdominal hysterectomy was performed in 92.8% of the cases. The case fatality rate was 14.3% while the perinatal mortality rate was 64.3%. Conclusion Emergency peripartum hysterectomy is not uncommonly performed in our centre and extensive uterine rupture from prolonged obstructed labour is the most common indication. In addition, it is associated with significant maternal and perinatal mortality. There is need to enlighten women in our communities on the benefits of ANC and hospital delivery as well as the dangers of delivering without skilled attendance. Government should consider enacting legislation to discourage people or organisations who operate unlicensed maternity homes in our environment. PMID:24147186

Mainstreaming of Climate Change into the Ghanaian Tertiary Educational System  

NASA Astrophysics Data System (ADS)

The impact of Climate Change has a far-reaching implication for economies and people living in the fragile Regions of Africa analysts project that by 2020, between 75 million and 250 million people will be exposed various forms of Climate Change Stresses. Education as a key strategy identified under Agenda 21 has been incorporated into the efforts of various educational institutions as a means of mitigating climate change and enhancing sustainability. Climate Change education offers many opportunities and benefits for educators, researchers, learners, and for wider society, but there are also many challenges, which can hinder the successful mainstreaming of climate change education. The study aims at understanding barriers for Climate Change Education in selected tertiary institutions in Ghana. The study was conducted among Geoscience Departments of the 7 main public universities of Ghana. The transcript analysis identified issues that hinders the mainstreaming of Climate Change, these includes existing levels of knowledge and understanding of the concept of climate change, appreciating the threshold concepts, ineffective teaching of Climate Change and some Departments are slow in embracing Climate Change as a discipline. Hence to develop strategies to mainstream climate change education it is important to recognise that increasing the efficiency and delivery of Climate Change education requires greater attention and coordination of activities and updating the educators knowledge and skill's. Various Ministries should be challenged to develop and integrate climate change into education policies. In the design of curriculum, there is a need to integrate Climate Change Education into curricula without compromising already overstretched programmes of study. There is a need to encourage and enhance innovative teaching approaches such as Problem-based learning (PBL) is an approach that challenges students to learn through engagement in a real problem. Institutions and Educator should be encouraged to undertake co-curricula activities and finding ways to practicalize Climate Change education.

Operative treatment of tertiary hyperparathyroidism: a single-center experience.  

PubMed Central

OBJECTIVE: To review the experience with the operative treatment of tertiary hyperparathyroidism (TH) from a single renal transplant center. SUMMARY BACKGROUND DATA: Most patients with chronic renal failure show evidence of secondary hyperparathyroidism by the time maintenance hemodialysis begins. Persistent secondary hyperparathyroidism (i.e., TH) requiring surgical intervention is uncommon in the authors' experience. METHODS: Charts of patients who underwent parathyroidectomy for TH were reviewed retrospectively. Information obtained included demographics, laboratory data, symptoms, operative procedure (including morbidity and mortality rates), and pathology. Comparisons of demographic data and allograft survival were made between the transplant population as a whole and a matched cohort group of patients. RESULTS: Thirty-eight patients from 4344 renal transplant procedures during a 29-year period required parathyroidectomy for TH. All patients had hypercalcemia; 20 were asymptomatic and 18 had varying symptoms. Mean time from renal transplantation to parathyroidectomy was 997 +/- 184 days, with a mean preoperative calcium level of 12.2 +/- 0.14 mg/dl. Total parathyroidectomy with parathyroid autograft was performed in 26 of 34 primary procedures. There were no deaths. The operative morbidity rate was 6% (wound separation and vocal cord hemiparesis, one each). Pathology was reported in all patients and recently reviewed in 28 patients. Twenty-four had diffuse hyperplasia and nine had nodular hyperplasia; one had an adenoma. Parathyroid glands diagnosed as nodular hyperplasia were significantly larger by total mass than those with diffuse hyperplasia. Comparison of allograft survival between the study group and a matched cohort group of patients revealed no difference in long-term graft survival. CONCLUSIONS: Operative intervention is recommended in patients with an asymptomatic increase in serum calcium to >12.0 mg/dl persisting for >1 year after the transplant, acute hypercalcemia (calcium >12.5 mg/dl) in the immediate posttransplant period, and symptomatic hypercalcemia.

Extraterrestrial amino acids at the Cretaceous-Tertiary boundary  

SciTech Connect

The Earth has apparently been impacted by numerous large asteroids (>10 km diameter) or comets throughout its history. The rate of these collisions is roughly 2-4 x 10/sup -8/ events yr/sup -1/. The collision of a large asteroid or comet with the Earth could result in the addition of extra-terrestrial organic compounds. Certain types of meteorites (C2-carbonaceous chondrites) contain a vast assortment of organics, including amino acids, aliphatic and aromatic hydrocarbons, carboxylic acids, heterocycles, and various low molecular weight compounds. Molecules important in abiotic organic syntheses are present in comets, and thus these objects are also likely rich inorganics. The authors have investigated whether the amino acid ..cap alpha..-amino isobutyric acid (AIBA) can be used to ascertain whether extraterrestrial amino acids (ETAA) were added to the Earth's surface at the proposed asteroid or comet impact event associated with the Cretaceous-Tertiary (K-T) boundary. AIBA was utilized in these studies since it is a dominant amino acid in C2-carbonaceous meteorites and only rarely occurs in terrestrial organisms. Detection of AIBA was performed using OPA pre-column derivatization-HPLC methodology. Since the AIBA fluorescent yield is increased relative to non ..cap alpha..-methyl substituted amino acids at elevated temperatures, derivatization was carried out at both room temperature and 90/sup 0/C. Ocean sediments of various geological ages were analyzed. The results indicate that only in DSDP Leg 43 K-T boundary samples are detectable levels of AIBA present.

Late Tertiary paleogeographic and tectonic evolution of the Mediterranean area  

SciTech Connect

The present geography of the Mediterranean Sea is the result of late Tertiary tectonic processes and hardly reflects its Mesozoic and early Tertiary evolution. This paper outlines a plate tectonics model for the Mediterranean area from the Oligocene to the Pliocene. Seismic and well data have been integrated into the regional structural framework to produce a set of paleogeographic maps, which includes the Oligocene, early and middle Miocene, late Miocene, and Pliocene. These maps highlight the changes in sedimentation patterns in response to the tectonic development of the Mediterranean area. Special attention will be given to the Messinian desiccation event.

An atmospheric pCO2 reconstruction across the Cretaceous-Tertiary boundary from leaf megafossils.  

PubMed

The end-Cretaceous mass extinctions, 65 million years ago, profoundly influenced the course of biotic evolution. These extinctions coincided with a major extraterrestrial impact event and massive volcanism in India. Determining the relative importance of each event as a driver of environmental and biotic change across the Cretaceous-Tertiary boundary (KTB) crucially depends on constraining the mass of CO(2) injected into the atmospheric carbon reservoir. Using the inverse relationship between atmospheric CO(2) and the stomatal index of land plant leaves, we reconstruct Late Cretaceous-Early Tertiary atmospheric CO(2) concentration (pCO(2)) levels with special emphasis on providing a pCO(2) estimate directly above the KTB. Our record shows stable Late Cretaceous/Early Tertiary background pCO(2) levels of 350-500 ppm by volume, but with a marked increase to at least 2,300 ppm by volume within 10,000 years of the KTB. Numerical simulations with a global biogeochemical carbon cycle model indicate that CO(2) outgassing during the eruption of the Deccan Trap basalts fails to fully account for the inferred pCO(2) increase. Instead, we calculate that the postboundary pCO(2) rise is most consistent with the instantaneous transfer of approximately 4,600 Gt C from the lithic to the atmospheric reservoir by a large extraterrestrial bolide impact. A resultant climatic forcing of +12 W.m(-2) would have been sufficient to warm the Earth's surface by approximately 7.5 degrees C, in the absence of counter forcing by sulfate aerosols. This finding reinforces previous evidence for major climatic warming after the KTB impact and implies that severe and abrupt global warming during the earliest Paleocene was an important factor in biotic extinction at the KTB.

Prevalence of gestational diabetes mellitus & associated risk factors at a tertiary care hospital in Haryana  

PubMed Central

Background & objectives: Prevalence of gestational diabetes mellitus (GDM) is known to vary widely depending on the region of the country, dietary habits, and socio-economic status. This study was undertaken to determine the prevalence of GDM and risk factors associated with it, in women attending an antenatal care (ANC) clinic at a tertiary care hospital in Haryana. Methods: This study enrolled women, with their estimated gestational age between 24th and 28th week, attending antenatal care (ANC) clinic at a tertiary care hospital in Rohtak. After informing, women who consented to participate were given a standardized 2-h 75 g oral glucose tolerance test (OGTT). A proforma containing general information on demographic characteristics, socio-economic status, education level, parity, family history of diabetes and/or hypertension and past history of GDM was filled up. American Diabetes Association (ADA) criteria for 75 g 2-h OGTT was used for diagnosing GDM. Results: A total of 607 women participated in the study and GDM was diagnosed in 43 (7.1%) women. A single abnormal value was observed in additional 66 (10.87%) women. On bivariate analysis risk factors found to be significantly associated with GDM were age, educational level, socio-economic status, pre-pregnancy weight and BMI, weight gain, acanthosis nigricans, family history of diabetes or hypertension and past history of GDM but on multivariate analysis only upper middle class and presence of acanthosis nigricans were found to be significantly associated with GDM. Interpretation & conclusions: The prevalence of GDM was found to be 7.1 per cent in a tertiary care hospital in Haryana. Appropriate interventions are required for control and risk factor modifications. PMID:23703340

Tertiary architecture of the Oceanobacillus iheyensis group II intron  

SciTech Connect

Group II introns are large ribozymes that act as self-splicing and retrotransposable RNA molecules. They are of great interest because of their potential evolutionary relationship to the eukaryotic spliceosome, their continued influence on the organization of many genomes in bacteria and eukaryotes, and their potential utility as tools for gene therapy and biotechnology. One of the most interesting features of group II introns is their relative lack of nucleobase conservation and covariation, which has long suggested that group II intron structures are stabilized by numerous unusual tertiary interactions and backbone-mediated contacts. Here, we provide a detailed description of the tertiary interaction networks within the Oceanobacillus iheyensis group IIC intron, for which a crystal structure was recently solved to 3.1 {angstrom} resolution. The structure can be described as a set of several intricately constructed tertiary interaction nodes, each of which contains a core of extended stacking networks and elaborate motifs. Many of these nodes are surrounded by a web of ribose zippers, which appear to further stabilize local structure. As predicted from biochemical and genetic studies, the group II intron provides a wealth of new information on strategies for RNA folding and tertiary structural organization.

Annual Technical Progress Report - West Hackberry Tertiary Project  

SciTech Connect

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. Air injection on the west flank 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 downstructure well.

A retrospective look at students enrolled in an upper-level horse science class: factors that affect classroom performance.  

PubMed

The objective of this study was to retrospectively analyze demographic variables and academic preparation of students to determine how these factors relate to student performance in ASI 521 Horse Science, an upper-level course offered in the Department of Animal Sciences and Industry (ASI) at Kansas State University (KSU). Data were collected for 264 students enrolled in the course from 2008 to 2010. Students who took the course in 2008 received greater final percentages than those who took the course in subsequent years (P = 0.0016). Females tended to receive greater percentages than males (P = 0.096). Location of origin of students did not affect percentages earned (P > 0.26). Although class standing (P = 0.35) did not affect the final percentages that students earned, transfer students received lesser final percentages in the course (P = 0.020). If students were majoring in ASI, they fared better than those in other majors (P = 0.0097), but pre-veterinary medicine students performed similarly to non-pre-veterinary students (P = 0.49). Enrollment in the equine certificate program (which requires students to complete 20 credit hours of equine coursework) did not affect percentages earned (P = 0.89) nor did completion of any individual equine class before enrolling in ASI 521 (P > 0.19). Test scores earned on the American College Testing Program standardized test during high school were not reflective of classroom performance (P = 0.51), but KSU grade point average (GPA) was highly predictive (P < 0.0001), regardless of the term for which GPA was calculated. Students in the course took an identical comprehensive test at the beginning and end of the semester, and those test scores were also predictive of final percentage earned in ASI 521 (P ? 0.0002). In general, students with greater GPA performed better in ASI 521, so strategies aimed at improving classroom performance may best be targeted toward students with histories of poor academic performance.

Formaldehyde formation from tertiary amine derivatives during chlorination.  

PubMed

In May 2012, formaldehyde (FA) precursor contamination in the Tone River Basin led to the suspension of water supply to approximately 360,000 homes, which affected approximately 870,000 people in the Tokyo Metropolitan Area. The discharge of industrial effluents containing hexamethylenetetramine (HMT), a tertiary amine and FA precursor, without proper treatment resulted in the formation of FA during chlorination at water purification plants. Tertiary amines are known to be the precursors of aldehydes upon chlorination. In this study, FA formation from 29 separate amine derivatives during chlorination was investigated to determine any other potential causes of this water quality accident. The FA formation yield also included FA formation by the autolysis of the target compounds as well as the chlorination of the autolysis products. The FA molar formation yield of HMT was the highest after 24h of chlorination (440%). Among the various tertiary amine derivatives containing N-methyl groups, tertiary amines and hydrazines were found to be strong FA precursors because the FA molar formation yields per N-methyl group ranged from 25% to 45% (with a mean of 38%) and from 35% to 45% (with a mean of 41%), respectively. Guanidines and sulfamides containing N-methyl groups were also FA precursors but they exhibited lower FA molar formation yields per N-methyl group. The FA molar formation yields of the remaining compounds were <4%. The FA formation yield of HMT was extremely high even on a per weight basis (95 wt.%). The FA weight formation yields of some tertiary amines and hydrazines were greater than 20 wt.%. PMID:24836388

Primary, secondary and tertiary effects of eco-climatic change: the medical response.  

PubMed

Climatic and ecological change threaten human health globally. Manifestations include lost species, vanishing glaciers and more frequent heavy rain. In the second half of this century, accelerating sea level rise is likely to cause crop loss, and population dislocation. These problems may be magnified by dysfunctional human responses, including conflict. The population health consequences of these events can be classified as primary, secondary and tertiary. Primary signs include the acute and chronic stress of heat waves, and trauma from increased bush fires and flooding. Secondary signs are indirect, such as an altered distribution of arthropod vectors, intermediate hosts and pathogens that will produce changes in the epidemiology of many infectious diseases. More severe future health consequences of climate change are classified here as tertiary effects. If moderate or severe climate change scenarios prove accurate then these manifestations will occur over large areas, and could include famine, war and significant population displacement. Such effects would threaten governance and health. The health professions must respond to these challenges, especially the task of recognising and seeking to minimise tertiary health consequences. The gap between what we know and what we need to know concerning these issues can be narrowed by a new field of medical practice. The framework for this emerging discipline includes climate change, ecology and global health. Combined, these dimensions may be called ecomedicine. Actions to reduce individual emissions, to promote active transport (with its 'co-benefit' of preventing chronic disease), and involvement in group action to protect the environment and to prevent war, informed by understanding of the health of individual patients and populations, will be central to the practice of ecomedicine.

Design of a compliant passive magnetic bearing for use in SIRTF's Tertiary Mirror Assembly  

NASA Technical Reports Server (NTRS)

A proposed baseline design for the Space Infrared Telescope Facility includes a Tertiary Mirror Assembly (TMA) which selectively redirects the telescope's converging science beam to each of several instruments. The TMA's mirror rotates on an axis coincident with the beam's axis, and is held steady during observation by a kinematic mount. A bearing has been designed whose compliance causes minimal interference with the precision of the kinematic mount, and which is well suited to the particular requirements of a cryogenic satellite such as SIRTF. The bearing suspends its rotor by taking advantage of the repulsion between a superconductor and a magnet. It potentially eliminates problems associated with mechanical bearings that arise in similar applications, such as lubricant loss or failure, bearing wear, and sensitivity to particulates, and does so without imposing the thermal load of a bearing heater or active magnetic bearing. The bearing shows promise of offering an alternative to ball bearings in cryogenic applications where some compliance is acceptable or advantageous.

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

NASA Astrophysics Data System (ADS)

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.

Population-level assessments should be emphasized over community/ecosystem-level assessments. Environmental Sciences Division Publication No. 1535. [Concerning the impact of power plants on fish populations  

SciTech Connect

Arguments are presented in favor of emphasizing population-level assessments over community/ecosystem-level assessments. The two approaches are compared on each of four issues: (1) the nature of entrainment/impingement impacts; (2) the ability to forecast reliably for a single fish population as contrasted to the ability to forecast for an aquatic community or ecosystem; (3) practical considerations involving money, manpower, time, and the need to make decisions; and (4) the nature of societal and economic concerns. The conclusion on each of these four issues is that population-level assessments provide the optimal approach for evaluating the effects of entrainment and impingement mortality.

Use of Treated Municipal Wastewater as Power Plant Cooling System Makeup Water: Tertiary Treatment versus Expanded Chemical Regimen for Recirculating Water Quality Management  

SciTech Connect

Treated municipal wastewater is a common, widely available alternative source of cooling water for thermoelectric power plants across the U.S. However, the biodegradable organic matter, ammonia-nitrogen, carbonate and phosphates in the treated wastewater pose challenges with respect to enhanced biofouling, corrosion, and scaling, respectively. The overall objective of this study was to evaluate the benefits and life cycle costs of implementing tertiary treatment of secondary treated municipal wastewater prior to use in recirculating cooling systems. The study comprised bench- and pilot-scale experimental studies with three different tertiary treated municipal wastewaters, and life cycle costing and environmental analyses of various tertiary treatment schemes. Sustainability factors and metrics for reuse of treated wastewater in power plant cooling systems were also evaluated. The three tertiary treated wastewaters studied were: secondary treated municipal wastewater subjected to acid addition for pH control (MWW_pH); secondary treated municipal wastewater subjected to nitrification and sand filtration (MWW_NF); and secondary treated municipal wastewater subjected nitrification, sand filtration, and GAC adsorption (MWW_NFG). Tertiary treatment was determined to be essential to achieve appropriate corrosion, scaling, and biofouling control for use of secondary treated municipal wastewater in power plant cooling systems. The ability to control scaling, in particular, was found to be significantly enhanced with tertiary treated wastewater compared to secondary treated wastewater. MWW_pH treated water (adjustment to pH 7.8) was effective in reducing scale formation, but increased corrosion and the amount of biocide required to achieve appropriate biofouling control. Corrosion could be adequately controlled with tolytriazole addition (4-5 ppm TTA), however, which was the case for all of the tertiary treated waters. For MWW_NF treated water, the removal of ammonia by nitrification helped to reduce the corrosivity and biocide demand. Also, the lower pH and alkalinity resulting from nitrification reduced the scaling to an acceptable level, without the addition of anti-scalant chemicals. Additional GAC adsorption treatment, MWW_NFG, yielded no net benefit. Removal of organic matter resulted in pitting corrosion in copper and cupronickel alloys. Negligible improvement was observed in scaling control and biofouling control. For all of the tertiary treatments, biofouling control was achievable, and most effectively with pre-formed monochloramine (2-3 ppm) in comparison with NaOCl and ClO2. Life cycle cost (LCC) analyses were performed for the tertiary treatment systems studied experimentally and for several other treatment options. A public domain conceptual costing tool (LC3 model) was developed for this purpose. MWW_SF (lime softening and sand filtration) and MWW_NF were the most cost-effective treatment options among the tertiary treatment alternatives considered because of the higher effluent quality with moderate infrastructure costs and the relatively low doses of conditioning chemicals required. Life cycle inventory (LCI) analysis along with integration of external costs of emissions with direct costs was performed to evaluate relative emissions to the environment and external costs associated with construction and operation of tertiary treatment alternatives. Integrated LCI and LCC analysis indicated that three-tiered treatment alternatives such as MWW_NSF and MWW_NFG, with regular chemical addition for treatment and conditioning and/or regeneration, tend to increase the impact costs and in turn the overall costs of tertiary treatment. River water supply and MWW_F alternatives with a single step of tertiary treatment were associated with lower impact costs, but the contribution of impact costs to overall annual costs was higher than all other treatment alternatives. MWW_NF and MWW_SF alternatives exhibited moderate external impact costs with moderate infrastructure and chemical conditioner dosing, which makes them (especially

A study of the association of attitudes to the philosophy of science with classroom contexts, academic qualification and professional training, amongst A level biology teachers in Harare, Zimbabwe  

NASA Astrophysics Data System (ADS)

The responses from 33 A level biology teachers to a questionnaire were analysed to test for association between attitude to the philosophy of science and academic qualification professional training. The teachers in Harare, Zimbabwe, also self-reported on their school contexts. From the school context data the teachers were clustered to give two different clusters - richer and poorer schools. Teachers in the poorer school context cluster showed statistically significant differences from those in the richer school context cluster in their attitudes to the philosophy of science. Teachers in the richer schools had more relativist and deductivist attitudes while teachers in the poorer context clusters were more positivist and inductivist. Richer schools are able to employ teachers who are academically and professionally better qualified. This evidence suggests the differential distribution of facilities and resources across school contexts reinforces the differential distribution of attitudes to the philosophy of science.

Tertiary paleomagnetism of regions around the South China Sea  

NASA Astrophysics Data System (ADS)

Paleomagnetic data from the Philippine Sea Plate (PSP) reveal a history of plate-wide clockwise (CW) rotation and northerly translation since the late Eocene about a nearby pole to the east. The motion has generated left lateral oblique convergence between the Philippine Sea Plate and S.E. Asia. Paleomagnetic data from Luzon in the northern Philippines show early Miocene CCW rotation followed by late Miocene CW rotation. In contrast, the Southern and Central Philippines display early Miocene CW rotation and unrotated late Miocene directions. These results define two different paleomagnetic domains with distinct post early Miocene histories. Pre-Miocene CCW rotation is suggested by data from Zambales, the Visayas and the Celebes Sea. In Borneo, a history of Tertiary CCW rotation has been found in Sarawak, and Sabah. Conflicting results have been reported from Kalimantan, some show no rotation with respect to Eurasia, while others give CCW rotations. In the Malaysian peninsula, the Segamat basalts and Kuantan dykes, of probable late Cretaceous early Tertiary age show CCW rotations similar to those seen in Sarawak. To the north peninsular Thailand, CW rotations have been found in two Miocene non-marine basins. Late Tertiary basalts from Northern and Central Thailand yield similar CW rotations while coeval flows on the Khorat plateau in Eastern Thailand are unrotated. The tectonic implications of the results remain problematical. In particular, the relative importance of true plate rotations and localized rotation of upper crustal blocks in distributed shear zones is unclear. The substantial region of CCW rotation in Borneo, the Celebes Sea and the Philippines is consistent with the broad features of the Holloway model, although the timing of the rotations precludes simple coherent rotation. The model must also be modified to include the effect of the left lateral oblique convergence between the PSP and Eurasia. The CW rotations seen in peninsular Thailand and Malaysia are consistent with the propagating extrusion tectonic model, but we cannot yet preclude a local transtensional origin for these rotations. The lack of Tertiary rocks in the peninsula has hampered attempts to relate these late Tertiary CW rotations to the late Mesozoic and Tertiary CCW rotations seen in Malaysia and Borneo.

Building an electronic book on the Internet: ``CSEP -- an interdisciplinary syllabus for teaching computational science at the graduate level``  

SciTech Connect

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.

Evidence from paleosols for ecosystem changes across the Cretaceous/Tertiary boundary in eastern Montana  

NASA Astrophysics Data System (ADS)

Ancient soils (paleosols) of the latest Cretaceous Hell Creek Formation are mildly calcareous, have clayey subsurface (Bt) horizons, and exhibit abundant large root traces, as is typical of forested soils in subhumid climates. The fact that some of the paleosols are capped by thin, impure coals is evidence for seasonally dry swamps. The paleosol evidence thus supports published reconstructions, based on fossil leaves, pollen, and vertebrates, that this area was subtropical, seasonally dry, subhumid, and forested mainly by angiosperms. Paleosols within the earliest Tertiary (Paleocene) Tullock Formation have thicker, coaly, surface (O and A) horizons and are more drab colored and less calcareous than paleosols of the Hell Creek Formation. These features are indications of waterlogging and of a humid climate. Large root traces and clayey subsurface (Bt) horizons are evidence of swamp woodland and forest. Inferred base level and paleoclimate are compatible with evidence from fossil leaves and pollen that indicates more abundant deciduous, early successional angiosperms and swamp conifers compared to those of Late Cretaceous time. Most of the paleosols have drab Munsell hues and can be expected to preserve a reliable fossil record of pollen and other plant remains. The carbonate content of the paleosols declines toward the top of the Hell Creek Formation, and the uppermost 3 m of the formation is noncalcareous. Because of this, the decline in diversity and abundance of bone over this interval is interpreted as a taphonomic artifact. Evidence from paleosols supports paleobotani-cal evidence for catastrophic change in ecosystems at the Cretaceous/Tertiary boundary.

Association of oil source algae in some Tertiary basins, northern Thailand  

NASA Astrophysics Data System (ADS)

A coal petrographic study of sediments, including coals, oil shale, and oil source rocks, in the fossil fuel deposits of northern Thailand revealed changes in alginite associations. In the Lower part of these Tertiary deposits, especially in the Fang oilfield, alginite A (a Botryococcus sp.) was the only type of alga found. Later, the association of Botryococcus braunii, Pila algae, thick-walled alginite B, and temperate palynomorphs were recognized in many coalfields, as well as in the middle part of the deposits in the Fang Basin. Their ages were Late Oligocene (?) to Early Miocene. In the upper part of the fossil fuel deposits, alginite B is dominant in many basins, together with Botryococcus-related taxa such as Pila algae, Reinschia and fresh-water-dwelling ferns. In the Mae Sod Basins Reinschia was found to be dominant in the northern part, whereas lamaginite dominated in the south, showing different environmental conditions in different parts of the basin during deposition. These different associations indicate changes in depositional environments in northern Thailand, resulting from climatic and/or sea level changes during Tertiary time.

Pandemic influenza: Experience in a flu OPD of a tertiary care hospital  

PubMed Central

Background In April 2009, Mexican health authorities announced an outbreak of a novel H1N1 influenza virus, which subsequently caused a pandemic. The world is now moving into the post-pandemic period. The experience gained in handling this pandemic at various levels under different settings has provided us many lessons for the future. Objective To study the profile of various activities undertaken at flu screening centre as a response to pandemic influenza in a tertiary care hospital. Methods Record-based study conducted in a tertiary care hospital of Pune. Required data was collected from records of flu OPD, ward and local health authority and interviewing related staff. Study included data from October 2009 to October 2010. Results A total of 8020 people presenting with influenza like illness (ILI) were screened in the flu OPD under study. Out of these, only 388 (4.84%) met clinical criteria where throat samples were collected, out of which only 81 were found to be positive (20.88%). Total three fatalities (3.7%) occurred out of 81 who had tested positive. Most cases of flu were managed at home (76.54%) while only 19 (23.4%) lab confirmed cases of H1N1 required hospitalisation. Conclusion Majority of cases of H1N1 (2009) were managed at home. Early diagnosis, quick initiation of treatment, infection control measures, and good care at the hospital can effectively reduce morbidity and mortality in H1N1 pandemic. PMID:24623946

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

NASA Astrophysics Data System (ADS)

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.

Tertiary and Quaternary Research with Remote Sensing Methods  

NASA Technical Reports Server (NTRS)

Problems encountered in mapping the Quaternary section of the Wind River Region using remote sensing methods are discussed. Analysis of the stratigraphic section is a fundamental aspect of the geologic study of sedimentary basins. Stratigraphic analysis of post-Cretaceous rocks in the Wind River Basin encounters problems of a distinctly different character from those involved in studying the pre-Cretaceous section. The interior of the basin is predominantly covered by Tertiary and Quaternary sediments. These rocks, except on the basin margin to the north, are mostly flat lying or gently dipping. The Tertiary section consists of sandstones, siltstones, and tuffaceous sediments, some variegated, but in general poorly bedded and of great lithologic similarity. The Quaternary sediments consist of terrace, fan, and debris tongue deposits, unconsolidated alluvium occupying the bottoms of modern watercourses, deposits of eolian origin and tufa. Terrace and fan deposits are compositionally diverse and reflect the lithologic diversity of the source terranes.

TMT tertiary mirror axis calibration with laser tracker  

NASA Astrophysics Data System (ADS)

To calibrate the tracing performance of the thirty meter telescope (TMT) tertiary mirror, for the special requirement of the TMT, the laser tracker is used to verify the motion. Firstly, the deviation is divided into two parts, namely, the repeatable error and the unrepeatable part. Then, based on the laser tracker, the mearturement and evalutation methods of the rigid body motion for the mirror are established, and the Monte Carol method is used to determine the accuracy of the mothod. Lastly, the mothod is applied to the turn table of a classical telescope and the residual error is about 4 arc second. The work of this paper will guide the next desgin and construction work of the thirty meter telescope tertiary mirror.

Tertiary side resonant DC/DC converter with integrated magnetics  

SciTech Connect

This paper presents a constant frequency tertiary side resonant dc/dc converter topology. The proposed converter topology gives the opportunity to integrate all the resonant inductors with the output transformer and provides greater flexibility in selecting the resonant capacitors. The harmonic equivalent circuit model and frequency domain analysis, which incorporates the effect of the leakage inductance of the high frequency transformer are presented. Steady state characteristics curves are presented to describe the effect of the leakage inductance and resonant circuit parameters on the performance of the converter. It is shown that with a tuned parallel resonant circuit on the tertiary winding the converter can be operated at higher frequencies. Finally, the experimental results show a higher than 80% efficiency for a 500 W, 48V to 5V dc/dc converter operating at 128 kHz.

General allylic C-H alkylation with tertiary nucleophiles.  

PubMed

A general method for intermolecular allylic C-H alkylation of terminal olefins with tertiary nucleophiles has been accomplished employing palladium(II)/bis(sulfoxide) catalysis. Allylic C-H alkylation furnishes products in good yields (avg. 64%) with excellent regio- and stereoselectivity (>20:1 linear:branched, >20:1 E:Z). For the first time, the olefin scope encompasses unactivated aliphatic olefins as well as activated aromatic/heteroaromatic olefins and 1,4-dienes. The ease of appending allyl moieties onto complex scaffolds is leveraged to enable this mild and selective allylic C-H alkylation to rapidly diversify phenolic natural products. The tertiary nucleophile scope is broad and includes latent functionality for further elaboration (e.g., aliphatic alcohols, ?,?-unsaturated esters). The opportunities to effect synthetic streamlining with such general C-H reactivity are illustrated in an allylic C-H alkylation/Diels-Alder reaction cascade: a reactive diene is generated via intermolecular allylic C-H alkylation and approximated to a dienophile contained within the tertiary nucleophile to furnish a common tricyclic core found in the class I galbulimima alkaloids.

A study on poisoning cases in a tertiary care hospital  

PubMed Central

Acute poisoning with various substance is common everywhere. The earlier the initial resuscitations, gastric decontamination and use of specific antidotes, the better the outcome. The aim of this study was to characterize the poisoning cases admitted to the tertiary care hospital, Warangal district, Andhra Pradesh, Southern India. All cases admitted to the emergency department of the hospital between the months of January and December, 2007, were evaluated retrospectively. We reviewed data obtained from the hospital medical records and included the following factors: socio-demographic characteristics, agents and route of intake and time of admission of the poisoned patients. During the outbreak in 2007, 2,226 patients were admitted to the hospital with different poisonings; the overall case fatality rate was 8.3% (n = 186). More detailed data from 2007 reveals that two-third of the patients were 21–30 years old, 5.12% (n = 114) were male and 3.23% (n = 72) were female, who had intentionally poisoned themselves. In summary, the tertiary care hospitals of the Telangana region, Warangal, indicate that significant opportunities for reducing mortality are achieved by better medical management and further sales restrictions on the most toxic pesticides. This study highlighted the lacunae in the services of tertiary care hospitals and the need to establish a poison information center for the better management and prevention of poisoning cases.

Extent of Delay in Diagnosis in New Smear Positive Patients of Pulmonary Tuberculosis Attending Tertiary Care Hospital  

PubMed Central

Background: India is the highest tuberculosis (TB) burden country accounting for one-fifth of the global incidence. It is estimated that, annually, 1.9 million cases are from India and about 0.8 million are infectious, new smear, positive pulmonary TB cases. The present study was a cross-sectional study conducted in a tertiary care hospital to determine the extent of delay in diagnosis and initiating the treatment after diagnosis in new smear, positive pulmonary TB patients attending a tertiary care hospital of Haryana during a 1-year period. Methods: A total of 204 patients were interviewed after being diagnosed as new sputum, positive TB (NSP-TB) by the treating doctor at the tertiary care hospital and re-interviewed at their home after initiation of anti-TB treatment. Chi-square test and analysis of variance (ANOVA) were used for statistical analysis. Results: More than half of the study patients delayed their first consultation with a health care system. The mean and median patient delay was 32.97 and 16 days, respectively. Lack of awareness of the disease was the leading cause for the patient delay. The mean duration of delay at peripheral health care provider was 60.46 days. The mean and median delay at tertiary care hospital was 8.35 and 4 days, respectively. Most of the patients delayed for diagnosis as per revised national TB control program (RNTCP) guidelines. The mean total delay in diagnosis was 75.71 days. Conclusions: There is an urgent need to scale up the information education communication activities to decrease the patient delay. Doctor at all level of health care need to be actively involved for subjecting the suspects to sputum examination at the earliest possible, as per RNTCP guidelines. PMID:24498507

Use of Earth Observing Satellite Data for the Development of "Learning Exercises" for College-Level Science Courses  

NASA Technical Reports Server (NTRS)

This paper is based on experiences being gained through a project entitled "The Mississippi Community College Pilot Project". The project was labeled "pilot" because it is thought that lessons learned during the implementation of this project may aid similar endeavors in other states. The objective of the project is to provide curriculum enrichment and associated faculty enhancement through the use of earth observations data in biological and physical sciences courses. The premise underlying the objective is that information from earth observations from satellite and aircraft platforms provides an effective means of illustrating and explaining science topics/phenomena in a new and/or different perspective. It is also thought that the use of data acquired from space may also serve to captivate the students interest and/or inquisitiveness about the particular science issue.

Tertiary Shortening at the Northeastern Margin of the Tibetan Plateau  

NASA Astrophysics Data System (ADS)

Although the Indo-Asian collision is the quintessential example of continental collision, the timing, extent, and distribution of Tertiary deformation around the current margins of the plateau are not well known. Two contrasting hypotheses for plateau growth exist: 1) shortening and crustal thickening occurred over a wide area during the Paleocene and Eocene, such that the plateau reached its present-day extent by Oligocene time, and 2) deformation progressively migrated north and east, such that the current margins of the plateau were not established until Late Miocene-Pliocene time. One means of testing between these two models is to establish estimates for the timing and magnitude of deformation at the edges of the plateau. At the northeast margin of the plateau, the Linxia basin experienced deposition of terrestrial sediments beginning in Oligocene time and continuing up into the Pliocene (Fang et al., 2003); however, little is known about the degree of deformation at the southern margin of the basin. Here we present new geologic mapping and preliminary stratigraphic observations along the southern margin of the Linxia basin. The basin margin is defined for nearly 90 km along strike by an E-W striking, north-vergent thrust system. Along the western section of the fault (near the Daxia river), Mesozoic and Paleozoic sediments are thrust over Tertiary basin sediments. A lack of cutoffs precludes a precise estimate of shortening. However, along the eastern segment (near the Tao river), Tertiary sediments are exposed both in the basin and in the hanging wall of the fault. Mapped relations indicate that the Tertiary conglomerates are folded over the basin-bounding structure and delineate significant deformation within the hanging-wall block. Stratal geometries exhibit up-section decreases in limb angle, indicative of progressive tilting during synchronous fold growth and sediment accumulation. We interpret geologic relations along this section of the Linxia Basin margin to reflect progressive deformation above a blind fault tip. Restoration of balanced cross-sections allows a preliminary estimate of the magnitude of Tertiary shortening along this margin of the Tibetan Plateau.

A Cretaceous-Tertiary mass extinction? Were most of Earth's species killed off?  

PubMed

For the past decade, the scientific and popular press have carried frequent articles about a catastrophic mass extinction that supposedly destroyed the majority of the earth's species, including the dinosaurs, approximately 65 million years ago. Since 1980, more than 2000 papers and books have dealt with some aspect of a mass extinction at the Cretaceous-Tertiary (K/T) boundary. One authoritative estimate of the severity of the extinctions is that 60-80% of all the living species became extinct at this boundary (Raup 1988). There appears to be a general acceptance of the fact that such a great catastrophe did occur. Most of the argument among scientists now is devoted to the determination of the cause. In this article, I argue that the species changes at the K/T boundary were neither sudden nor catastrophic. They were most likely caused by a regression of sea level that led to a decrease in primary production. PMID:11538279

The application of language-game theory to the analysis of science learning: Developing an interpretive classroom-level learning framework  

NASA Astrophysics Data System (ADS)

In this study an interpretive learning framework that aims to measure learning on the classroom level is introduced. In order to develop and evaluate the value of the framework, a theoretical/empirical study is designed. The researcher attempted to illustrate how the proposed framework provides insights on the problem of classroom-level learning. The framework is developed by construction of connections between the current literature on science learning and Wittgenstein's language-game theory. In this framework learning is defined as change of classroom language-game or discourse. In the proposed framework, learning is measured by analysis of classroom discourse. The empirical explanation power of the framework is evaluated by applying the framework in the analysis of learning in a fifth-grade science classroom. The researcher attempted to analyze how students' colloquial discourse changed to a discourse that bears more resemblance to science discourse. The results of the empirical part of the investigation are presented in three parts: first, the gap between what students did and what they were supposed to do was reported. The gap showed that students during the classroom inquiry wanted to do simple comparisons by direct observation, while they were supposed to do tool-assisted observation and procedural manipulation for a complete comparison. Second, it was illustrated that the first attempt to connect the colloquial to science discourse was done by what was immediately intelligible for students and then the teacher negotiated with students in order to help them to connect the old to the new language-game more purposefully. The researcher suggested that these two events in the science classroom are critical in discourse change. Third, it was illustrated that through the academic year, the way that students did the act of comparison was improved and by the end of the year more accurate causal inferences were observable in classroom communication. At the end of the study, the researcher illustrates that the application of the proposed framework resulted in an improved version of the framework. The improved version of the proposed framework is more connected to the topic of science learning, and is able to measure the change of discourse in higher resolution.

Tertiary siRNAs Mediate Paramutation in C. elegans  

PubMed Central

In the nematode Caenorhabditis elegans, different small RNA-dependent gene silencing mechanisms act in the germline to initiate transgenerational gene silencing. Piwi-interacting RNAs (piRNAs) can initiate transposon and gene silencing by acting upstream of endogenous short interfering RNAs (siRNAs), which engage a nuclear RNA interference (RNAi) pathway to trigger transcriptional gene silencing. Once gene silencing has been established, it can be stably maintained over multiple generations without the requirement of the initial trigger and is also referred to as RNAe or paramutation. This heritable silencing depends on the integrity of the nuclear RNAi pathway. However, the exact mechanism by which silencing is maintained across generations is not understood. Here we demonstrate that silencing of piRNA targets involves the production of two distinct classes of small RNAs with different genetic requirements. The first class, secondary siRNAs, are localized close to the direct target site for piRNAs. Nuclear import of the secondary siRNAs by the Argonaute HRDE-1 leads to the production of a distinct class of small RNAs that map throughout the transcript, which we term tertiary siRNAs. Both classes of small RNAs are necessary for full repression of the target gene and can be maintained independently of the initial piRNA trigger. Consistently, we observed a form of paramutation associated with tertiary siRNAs. Once paramutated, a tertiary siRNA generating allele confers dominant silencing in the progeny regardless of its own transmission, suggesting germline-transmitted siRNAs are sufficient for multigenerational silencing. This work uncovers a multi-step siRNA amplification pathway that promotes germline integrity via epigenetic silencing of endogenous and invading genetic elements. In addition, the same pathway can be engaged in environmentally induced heritable gene silencing and could therefore promote the inheritance of acquired traits. PMID:25811365

Ignition of global wildfires at the Cretaceous/Tertiary boundary  

NASA Technical Reports Server (NTRS)

The recent discovery of an apparently global soot layer at the Cretaceous/Tertiary boundary indicates that global wildfires were somehow ignited by the impact of a comet or asteroid. It is shown here that the thermal radiation produced by the ballistic reentry of ejecta condensed from the vapor plume of the impact could have increased the global radiation flux by factors of 50 to 150 times the solar input for periods ranging from one to several hours. This great increase in thermal radiation may have been responsible for the ignition of global wildfires, as well as having deleterious effects on unprotected animal life.

In situ reactive oxygen species production for tertiary wastewater treatment.  

PubMed

The goal of this research was to develop a new approach for tertiary water treatment, particularly disinfection and removal of refractory organic compounds, without adding any chemical. Hydrogen peroxide can indeed be produced from dissolved oxygen owing to electrochemical processes. Using various current intensities (1.0 to 4.0 A), it was possible to in situ produce relatively high concentration of H2O2 with a specific production rate of 0.05?×?10(-5) M/min/A. Likewise, by using ultraviolet-visible absorption spectroscopy method, it was shown that other reactive oxygen species (ROS) including HO(*) radical and O3 could be simultaneously formed during electrolysis. The ROS concentration passed from 0.45?×?10(-5) M after 20 min of electrolysis to a concentration of 2.87?×?10(-5) M after 100 min of electrolysis. The disinfection and the organic matter removal were relatively high during the tertiary treatment of municipal and domestic wastewaters. More than 90 % of organic compounds (chemical oxygen demand) can be removed, whereas 99 % of faecal coliform abatement can be reached. Likewise, the process was also effective in removing turbidity (more than 90 % of turbidity was removed) so that the effluent became more and more transparent. PMID:25483973

Explaining the uptake of paediatric guidelines in a Kenyan tertiary hospital – mixed methods research  

PubMed Central

Background Evidence-based standards for management of the seriously sick child have existed for decades, yet their translation in clinical practice is a challenge. The context and organization of institutions are known determinants of successful translation, however, research using adequate methodologies to explain the dynamic nature of these determinants in the quality-of-care improvement process is rarely performed. Methods We conducted mixed methods research in a tertiary hospital in a low-income country to explore the uptake of locally adapted paediatric guidelines. The quantitative component was an uncontrolled before and after intervention study that included an exploration of the intervention dose-effect relationship. The qualitative component was an ethnographic research based on the theoretical perspective of participatory action research. Interpretive integration was employed to derive meta-inferences that provided a more complete picture of the overall study results that reflect the complexity and the multifaceted ontology of the phenomenon studied. Results The improvement in health workers’ performance in relation to the intensity of the intervention was not linear and was characterized by improved and occasionally declining performance. Possible root causes of this performance variability included challenges in keeping knowledge and clinical skills updated, inadequate commitment of the staff to continued improvement, limited exposure to positive professional role models, poor teamwork, failure to maintain professional integrity and mal-adaptation to institutional pressures. Conclusion Implementation of best-practices is a complex process that is largely unpredictable, attributed to the complexity of contextual factors operating predominantly at professional and organizational levels. There is no simple solution to implementation of best-practices. Tackling root causes of inadequate knowledge translation in this tertiary care setting will require long-term planning, with emphasis on promotion of professional ethics and values and establishing an organizational framework that enhances positive aspects of professionalism. This study has significant implications for the quality of training in medical institutions and the development of hospital leadership. PMID:24613001

Effects of discipline-based art education and interdisciplinary art education on artistic development and production, higher-level thinking, and attitudes toward science and social studies  

NASA Astrophysics Data System (ADS)

This research was conducted to assess the effectiveness of discipline-based art education (DBAE) and interdisciplinary art (IA) teaching methods on art production, higher level thinking skills, and attitudes toward science and social studies. Two of the sixth-grade classes at a rural West Tennessee school were taught using the DBAE method and two were given the IA treatment. The evaluation of art production was two-fold using an Evaluation of Student Art Projects (Herberholz & Herberholz, 1994) which anonymously measured each group of projects on creativity, expressiveness, organization of elements and principles of art, craftsmanship, and how the artwork related to academic content. The second appraisal of art products involved emergent categorization with reference to Herberholz and Herberholz's (1994) categories of styles and student artistic development. Higher level thinking skills were determined from the Evaluation of Student Essays which measured academic knowledge, composition, and Bloom's higher level thinking stages of analysis, synthesis, and evaluation. Student attitudes toward social studies and science before and after treatment were measured using the Estes Attitude Survey (Estes, Johnstone, & Richards, 1975). T-tests, an analysis of variance (Anova) and data analysis were used to evaluate art production. T-tests were also used to evaluate student essays before and after each treatment. Analysis of data indicated no significant differences between the art products of students in DBAE or IA. There were no significant differences in the attitudes or higher level thinking skills between students undergoing the DBAE or IA treatment. The emergent categorization of art production showed that DBAE produced more overall creativity and originality than IA. The researcher believes that students can benefit from a combination of both methods.

"Actually, I May be Clever Enough to do it". Using Identity as a Lens to Investigate Students' Trajectories Towards Science and University  

NASA Astrophysics Data System (ADS)

We have followed a group of students in the potential pipeline for science through their last years of upper secondary school and in the context of a university mentorship program. The student group is defined by their choice of Mathematics at A-level which is mandatory for admission to tertiary STEM education in Denmark. Rich data (repeated interviews, questionnaires (pre-and post-) and observations) from 14 target students have been collected. Using Late Modern identity theory as a lens, we have analysed students' identity narratives in order to establish their trajectories in relation to university in general, and towards science studies and science careers in particular. We find that the diversity of students' educational identity narratives can be characterized and their trajectories understood in terms of a Four Factor Framework comprising: general identity process orientations (reflecting, committing, exploring), personal values, subject self-concepts and subject interests. In various ways these constructs interact and set the range and direction of the students' searches for future education and careers. Our longitudinal study suggests that they have enough permanence to enable us to hypothesize more or less secured paths of individual students to tertiary science (or other areas of academia).
