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.

Neonatal mortality: a scenario in a tertiary level hospital of a developing country  

PubMed Central

This study was designed to observe the overall neonatal mortality and pattern of neonatal death in a developing country. The factors related to neonatal mortality are also analyzed. This retrospective study was carried out in all pediatric patients in a tertiary level hospital of a developing country in the year 2008. Total neonatal (0–28 days) and non-neonatal (after 28 days-12 years) admissions and death records were analyzed. There were a total of 3,194 admissions in the year 2008. Neonatal and non-neonatal admissions numbered 942 and 2,252, respectively. There were a total of 146 (15.5%) neonatal deaths among neonatal admissions and 114 (5.06%) non-neonatal deaths among non-neonatal admissions. There were 87 (59.59%) preterm related deaths and 98 (67.12%) deaths due to Low Birth Weight (LBW). There were 102 (70%) deaths among neonates who had no antenatal follow-up. Mother's age was under 20 years in 80 (55%) cases of neonatal death. The number of neonatal deaths is high in developing countries. Preterm with Low Birth Weight (LBW) is the major cause of mortality. Regular antenatal care and social discouragement of early marriage can greatly reduce neonatal death. Skilled and trained nursing care is necessary for the survival of the preterm and Low Birth Weight (LBW) baby in the hospitals of developing countries. PMID:21589845

Pregnancy Outcome of Women With Gestational Diabetes in a Tertiary Level Hospital of North India  

PubMed Central

Background: Women with gestational diabetes mellitus (GDM) pose an important public health problem because diabetes not only affects the maternal and fetal outcome, but these women and their fetuses are also at an increased risk of developing diabetes and related complications later in their life. Objectives: The study was conducted to determine the maternal and fetal outcomes of 50 diabetic vs 50 normoglycemic pregnancies. Materials and Methods: This was a retrospective analytical record-based study conducted in a tertiary level hospital. Detailed information regarding maternal, fetal, and labor outcome parameters was recorded in a prestructured proforma and compared in normoglycemic and diabetic pregnancies. Results: Patients with obesity, history of diabetes in the family, spontaneous abortions, and gestational diabetes in previous pregnancies had a greater incidence of GDM in current pregnancy (P<0.05 for all). Hypertension, polyhydramnios, macrosomia, fetopelvic disproportion, and cesarean sections were more (P<0.001) among diabetic pregnancies. Congenital anomalies, polycythemia, hypocalcemia, and hyperbilirubinemia were also observed to be more (P<0.05) in neonates born to diabetics, suggesting an adverse effect of hyperglycemia in utero. Conclusion: Diabetes during pregnancy is associated with higher maternal and fetal morbidity. Therefore, early screening, detection, close monitoring, and intervention is essential to reduce maternal and fetal short- and long-term adverse effects, especially in high-risk groups. Pregnancy provides an opportunity to the clinician to control the disease process and inculcate healthy lifestyle practices in these patients. PMID:21976796

Acute Biliary Pancreatitis is one of the commonest forms of pancreatitis in Nepal. Controversies exist as to the most appropriate way of management of these cases. The present study was carried out to evaluate the management and outcome of Acute Biliary Pancreatitis cases in a tertiary level hospital of Nepal. A retrospective analysis of the patients managed with Acute Biliary Pancreatits was done. All patients admitted with the diagnosis of Acute Biliary Pancreatitis over a period of 2 years were included in the study. The variables measured were age, sex, clinical presentation, laboratory investigations, mode of treatment and outcome. A total of 45 cases had Acute Biliary Pancreatitis suggesting a prevalence of 28 %. The mean age was 45?±?10 year. 39 patients (86.6 %) were treated with conservative management. 23 patients (54 %) had an uneventful recovery without any complications. 21 patients (46 %) developed some form of complications but recovered successfully. Mortality was seen in only one patient in the conservatively treated group. In a resource poor setting such as Nepal, definitive management is not always possible. Conservative management of Acute Biliary Pancreatitis has a favorable outcome in the majority of our patients with acceptable morbidity and mortality. Definitive management can be safely performed during index admission where possible. PMID:24465101

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

PubMed Central

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

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

Emulsifying and interfacial properties of vicilins: role of conformational flexibility at quaternary and/or tertiary levels.  

PubMed

Although the functionality of plant proteins (and soy proteins in particular) has been widely investigated in the last decades, the importance of conformational characteristics to their functionalities is still far away from being understood. The aim of the present work was to unravel the role of conformational flexibility at the quaternary and/or tertiary levels in the emulsifying and interfacial properties of phaseolin, an ideal vicilin (or 7S globulin) from red kidney bean. The conformational flexibility at quaternary and tertiary levels of phaseolin was modulated by urea with increasing concentrations from 0 to 8 M, as characterized by using dynamic light scattering (DLS), intrinsic fluorescence and derivative UV spectroscopy, and differential scanning calorimetry (DSC). The emulsifying and interfacial properties, including emulsifying ability, flocculated state of oil droplets (in fresh emulsions), emulsion stability against creaming, and adsorption dynamics at the oil-water interface, were characterized at a specific protein concentration of 0.5% (w/v). The results indicated that increasing the urea concentration resulted in a progressive dissociation of trimeric phaseolin molecules into monomeric subunits, and even a structural unfolding of dissociated subunits; the urea-induced conformational changes at quaternary and/or tertiary levels were reversible, and the molecules at high urea concentrations shared similar structural features to the "molten globule state". On the other hand, increasing the urea concentration progressively improved the emulsifying ability of the protein, and flocculated extent of oil droplets in the fresh emulsions, but led to a progressive decrease in interfacial protein concentration. The improvement of the emulsifying ability was not related to diffusion (during initial adsorption) and penetration at the interface, but highly dependent on ease of structural rearrangement of the adsorbed proteins. These observations clearly confirmed that the flexibility of phaseolin at quaternary and/or tertiary levels plays a vital role in its emulsifying ability, mainly through the way of affecting the ease of structural rearrangement of adsorbed proteins at the interface. The findings could provide an in-depth understanding of the importance of conformational flexibility for the emulsifying properties of oligomeric storage globulins, and thus are of great help to guide the modifications of the proteins for better emulsifying properties.

Pattern of abortion care in a tertiary level maternity hospital in Nepal.  

PubMed

Introduction: Complications from unsafe abortion are believed to account for the largest proportion of hospital admissions for gynaecological services in developing countries and not to mention the cost it imparts to the health system of a country. Therefore, it is equally important to find out the prevalence and the pattern of abortion among the women who utilize the safe abortion care services and provide a framework to target various health promotion programs including safe-motherhood and reproductive health; such that the future interventions to avoid the unintended pregnancy and unsafe abortion can be implemented accordingly. Methods: A cross-sectional study was conducted in a tertiary care hospital in Kathmandu, Nepal. Social and demographic information of all the women seeking induced abortions from January 2011 to December 2012 were included and the result was analyzed. Result: Abortion contributed to about 1.68% of the total patient served in the hospital that provides both obstetrical and gynecological services. Of the total 4830 patients who underwent induced abortion in this period, the mean age was 27, 92.3% were from the Kathmandu valley and more than one-third women (35.2%) were illiterate who couldn't read and write. Majorities were more than two parity and belonged to higher caste. Conclusion: The socio-demographic profile of the abortion clients in Nepal has remained similar over the years. We need to address the accessibility and availability to the safe abortion care services along with other safe motherhood programs guaranteeing access to safe abortion and post-abortion care to all group of women and also, women education regarding contraception to avoid repeated abortions or unwanted pregnancy in the future. Keywords: abortion; pattern; socio-demographic. PMID:24907945

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.

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.

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

A single center multioperator initial experience of 4195 patients at a primary radial intervention program in a tertiary level center  

PubMed Central

Background There has been an increase the acceptability and the number of the procedures via the radial approach. We present our experience pertaining to the clinical characteristics, procedural details and post procedural outcome of patients undergoing radial artery access, coronary angiographies over a period of 4 years at a primary care tertiary level center. Materials and methods A retrospective analysis of all the coronary artery procedures during the last 4 years was done and the various parameters related to these procedures noted. Results In 4195 procedures performed, success in radial artery procedures was achieved in 3975 (94.8%) procedures. The average puncture time and total procedure time was 9.5 + 3 min (min) and 15 + 2.5 min in the initial 500 patients, whereas the times taken in the final 695 patients were just 1.5 + 0.5 min and 3.0 + 1.5 min respectively. The total fluoroscopy time was not significantly different among the groups, when performed by an operator with training in the femoral route for angiography. Cardiology fellows needed more fluoroscopy time when mastering the radial route. Crossover of access sites was seen in 220 patients (5.2%). Conclusions After 100 procedures, radial access coronary angiographies take less than 4.5 min, with first attempt radial artery access and negligible complication rates. Prior experience of coronary angiography helps in the reduction of fluoroscopy time during the learning curve. PMID:24814110

Profile of oral squamous cell cancer in a tertiary level medical college hospital: a 10 yr study.  

PubMed

To know the clinical and epidemiological characteristics & management strategies for the patients who underwent surgery for oral Squamous Cell Cancer (SCC) in a medical college hospital. Data pertaining to clinico-epidemiological factors & surgical management for oral cancer were analyzed in patients admitted to a tertiary level medical college hospital. Records of 139 patients admitted over a period of 10 years (January 1998 to December 2007) were used for data analysis. Only patients with complete records were included in the analysis. M: F ratio was 2.2:1 with average age of patients being 50.4 years. Tobacco chewing & smoking were major predisposing factors identified. Oral ulcer was the most common symptom while buccal mucosa, tongue & lower alveolus were three most common primary tumor sites. Majority of tumors were stage IV at presentation (52 %). Wide excision of tumor was done in 46 % of cases while in 54 % cases commando procedure was done. Reconstruction after either commando or wide excision was done in half of the patients. Pectoralis major myocutaneous (PMMC) flap was used in majority of cases for reconstruction. Neck dissection was done in 67 % patients. Majority (85 %) of these were radical neck dissection (RND). Per operative blood transfusions were required in 64 % patients while 19 % patients needed post operative transfusion. Post operative complications were noted in 34 % of the patients. Of these majority were related to wound infection & orocutaneous fistula formation. Hospital stay varied from 7 to 105 days with the mean duration of 30 days. Two year follow up revealed a recurrence rate of 36 %. Majority of the patients presented at an advanced stage due to self as well as professional delay in diagnosis. This leads to difficulty in resection of the primary tumor as well as reconstruction of the defect. A higher rate of recurrence after surgery is also seen. Post operative complications increase the morbidity which is reflected by an increase in the hospital stay (19 days Vs 46 days). PMID:23997517

This study examines exemplary science teachers' use of technology in science instruction, factors influencing their level of computer use, their level of knowledge/skills in using specific computer applications for science instruction, their use of computer-related applications/tools during their instruction, and their students' use of computer applications/tools in or for their science class. After a relevant review of the literature certain variables were selected for analysis. These variables included personal self-efficacy in teaching with computers, outcome expectancy, pupil-control ideology, level of computer use, age, gender, teaching experience, personal computer use, professional computer use and science teachers' level of knowledge/skills in using specific computer applications for science instruction. The sample for this study includes middle and high school science teachers who received the Presidential Award for Excellence in Science Teaching Award (sponsored by the White House and the National Science Foundation) between the years 1997 and 2003 from all 50 states and U.S. territories. Award-winning science teachers were contacted about the survey via e-mail or letter with an enclosed return envelope. Of the 334 award-winning science teachers, usable responses were received from 92 science teachers, which made a response rate of 27.5%. Analysis of the survey responses indicated that exemplary science teachers have a variety of knowledge/skills in using computer related applications/tools. The most commonly used computer applications/tools are information retrieval via the Internet, presentation tools, online communication, digital cameras, and data collection probes. Results of the study revealed that students' use of technology in their science classroom is highly correlated with the frequency of their science teachers' use of computer applications/tools. The results of the multiple regression analysis revealed that personal self-efficacy related to the exemplary science teachers' level of computer use suggesting that computer use is dependent on perceived abilities at using computers. The teachers' use of computer-related applications/tools during class, and their personal self-efficacy, age, and gender are highly related with their level of knowledge/skills in using specific computer applications for science instruction. The teachers' level of knowledge/skills in using specific computer applications for science instruction and gender related to their use of computer-related applications/tools during class and the students' use of computer-related applications/tools in or for their science class. In conclusion, exemplary science teachers need assistance in learning and using computer-related applications/tool in their science class.

Arrival time pattern and waiting time distribution of patients in the emergency outpatient department of a tertiary level health care institution of North India  

PubMed Central

Background: Emergency Department (ED) of tertiary health care institute in India is mostly overcrowded, over utilized and inappropriately staffed. The challenges of overcrowded EDs and ill-managed patient flow and admission processes result in excessively long waits for patients. Aim: The objective of the present study was to analyze the patient flow system by assessing the arrival and waiting time distribution of patients in an Emergency out Patient Department (EOPD). Materials and Methods: This short cross-sectional descriptive study was conducted in the EOPD of a Tertiary level health care Institution in North India in the month of May, 2011. The data was obtained from 591 patients, who were present in the EOPD during the month of May, 2011. The waiting time, inter arrival time between two consecutive patients were calculated in addition to the daily census data (discharge rate, admission rate and transfer out rates etc.) of the emergency. Results: Arrival time pattern of patients in the EOPD was highly stochastic with the peak arrival hours to be 9.00-12.00 h in which around 26.3% patients arrived in the EOPD. The primary waiting areas of patients included patients under observation (29.6%); waiting for routine diagnostic tests (16.4%) and waiting for discharge (14.6%). Around 71% patients were waiting due to reasons within emergency complex. Conclusion: The patient flow of the ED could only be addressed by multifaceted, multidisciplinary and hospital wide approach.

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

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.

A readability analysis of elementary-level science textbooks  

NASA Astrophysics Data System (ADS)

Given both the unprecedented attention to the importance of providing children with the best possible science textbooks and the overwhelming evidence that students in the United States are severely lacking the most basic science knowledge, the decline in the number of students pursuing science degrees is alarming. In spite of all the efforts being made, a disparity still exists between (1) the wealth of science information available, (2) the apparent ease of access to scientific information, and (3) the lack of scientific academic progress being made in classrooms across the United States. A literature review was conducted which included the areas of textbook analysis and textbook readability levels, the fields of textbook analysis and readability, and findings from recently published books about textbook readability. The majority of the literature reflected an urgent need for science textbooks to be revised. Based on the information gathered during the literature review, the study examined the readability levels of elementary level science textbooks that were published by six textbook publishers. Results from the study revealed that when used properly, readability formulas provide an objective look at textbooks. After applying these formulas to the selected elementary level science textbooks, it became clear that very few changes were implemented between the most recent previous editions and the current editions. The textbooks remain too difficult for the students using them. The findings from this study will help science textbook publishers and textbook writers see that some changes need to be made in the way their textbooks are written. In order to maintain a competitive edge in the global marketplace, more students need to pursue science. In order for more students to do that, they need to pursue science degrees, but in order for them to pursue science degrees, they need to have a certain degree of confidence and level of interest in the subject matter. For that to happen, science textbooks need to be more inviting, more user-friendly, and more interesting to the readers. This study concludes with recommendations for further research.

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

Striped tertiary storage arrays  

NASA Technical Reports Server (NTRS)

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

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.

A study of secondary science teacher efficacy and level of constructivist instructional practice implementation in West Virginia science classrooms  

NASA Astrophysics Data System (ADS)

The purpose of this study was to investigate the level of use of selected constructivist instructional practices and level of teacher efficacy in West Virginia secondary science classrooms. The study next sought to determine if a relationship existed between level of use of the constructivist practices and teacher efficacy. In addition the study sought to determine if differences existed in level of use of the selected constructivist practices and/or teacher efficacy based on selected demographic variables. The study was a mixed-methods design. First, a researcher-developed survey instrument was used to collect data regarding the level of use of constructivist instructional practices. Efficacy data were collected using an adapted (with permission) version of the Teacher Self-Efficacy Scale ( TSES) by Tschannen-Moran, Hoy, and Hoy (1998). The study population consisted of secondary science teachers (middle, junior, and high school) in the state of West Virginia. The last survey question allowed educators to volunteer for a short follow-up interview to clarify the quantitative data. Overall, West Virginia science teachers reported frequent use of the selected constructivist instructional practices. Few significant differences were found based on the selected demographic variables. West Virginia science teachers reported moderately high efficacy levels. Few significant differences were found based on selected demographic variables. A moderate but significant correlation was found between teacher efficacy level and the level of use of the selected constructivist practices. The follow-up interviews clarified concepts and revealed barriers to implementation of new practices in the science classroom.

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.

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

NASA Astrophysics Data System (ADS)

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

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.

Low-level radioactive waste regulation: Science, politics and fear  

SciTech Connect

An inevitable consequence of the use of radioactive materials is the generation of radioactive wastes and the public policy debate over how they will be managed. In 1980, Congress shifted responsibility for the disposal of low-level radioactive wastes from the federal government to the states. This act represented a sharp departure from more than 30 years of virtually absolute federal control over radioactive materials. Though this plan had the enthusiastic support of the states in 1980, it now appears to have been at best a chimera. Radioactive waste management has become an increasingly complicated and controversial issue for society in recent years. This book discusses only low-level wastes, however, because Congress decided for political reasons to treat them differently than high-level wastes. The book is based in part on three symposia sponsored by the division of Chemistry and the Law of the American Chemical Society. Each chapter is derived in full or in part from presentations made at these meetings, and includes: (1) Low-level radioactive wastes in the nuclear power industry; (2) Low-level radiation cancer risk assessment and government regulation to protect public health; and (3) Low-level radioactive waste: can new disposal sites be found.

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

NASA Astrophysics Data System (ADS)

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

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.

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.

Simulation of the response of carbonate sequences to Eustatic Sea level changes (Tertiary, northwest Great Bahama Bank): A scheme for enhancing seismic interpretation  

SciTech Connect

Seismic lines across northwestern Great Bahama Bank (GBB) show Vograding sequences with patterns most likely controlled by prevailing currents and sea level. To test this interpretation computer simulations were made to obtain a visual match between the seismic line and the SEDPAK simulation output. The initial topography, unidirectional wind, and sea level curve defined by Haq et al. were used as fixed inputs, with carbonate accumulation rate and subsidence as variables. Progradation in a buried, fault-bounded trough (Straits of Andros) began in the middle Oligocene. Simulation produced aggradation from the Late Cretaceous until the middle Oligocene. Afterward, sea level fall shifted the depocenter onto the slopes. Progradation was triggered during the subsequent sea level rise because the upper slope and platform edge remained in the photic zone for an extended period of high carbonate production. This increased rate of sedimentation initiated progradation on the western margin and on the eastern margin sedimentation was damped by intense wave action. On the western margin of GBB, where progradation probably began after the middle Miocene, the best simulation was obtained by incorporating a subsiding normal fault block underlying the Straits of Florida. This subsidence from the Late Cretaceous through middle Oligocene kept the deep shelf in the lower photic zone, preventing progradation during the middle Oligocene sea level lowstand. Simulation produced ongoing infilling of the basin that first flattened the margin into a ramp-type geometry over which margin progradation occurred subsequent to the next major sea level drop in the middle Miocene. This is consistent with the time suggested by seismic stratigraphy.

From inside the black box: Teacher perceptions of science instruction at the elementary level  

NASA Astrophysics Data System (ADS)

Science education reform projects aimed at elementary school children arose in the 1960's. The most prevalent of these reforms utilized the inquiry, or hands-on, science method. Billions of dollars have been invested in these reforms. Yet, reports indicate that science is not being taught at the level one might expect in elementary schools. This research was an analysis of the problems and concerns teachers at one school district faced as they tried to implement and sustain elementary inquiry science instruction. The district chosen was a large suburban district in the Western United States. The population was ninety percent Caucasian with a slightly more ethnically diverse school population. This district was chosen because it had an elementary science program for over twenty years and had received national acclaim for that program. The district had a stable and homogeneous staff there was a low administrator and teacher turnover rate and the elementary teaching population was ninety percent Caucasian and ninety percent female. Interviews with administrators and teachers were conducted. Data were collected from focus groups of teachers and science partners. Observations of elementary science classroom instruction and professional development sessions were made. Results of this research indicated that one important key to elementary science reform rests in the hands of teachers. Once the door to the classroom is closed, the teacher can decide to teach or not to teach science. The findings of this research illustrate that teachers hold ideas about science and science instruction that are antithetical to some tenets of inquiry science. Until these ideas are addressed it will be difficult, if not impossible, to implement a systemic elementary inquiry science program. This study demonstrates that professional development for elementary teachers in science needs to change from a focus on the mechanical usage of individual units to a focus on teacher expectations for student achievement. Professional development for teachers in inquiry science must address the cognitive foundations for inquiry science and the benefits students derive from this educational approach. Institutions delivering pre-service training for elementary teachers in science must change the curriculum to reflect these needs.

Use of a level 3 portable monitor for the diagnosis and management of sleep-disordered breathing in an inpatient tertiary care setting  

PubMed Central

Sleep-disordered breathing (SDB) encompasses a spectrum of disorders and may impact the course of medical illness and care among hospitalized patients. However, diagnosing SDB is a resource-intensive endeavour that often requires polysomnography, which limits its application. Portable monitors, on the other hand, have been validated for the diagnosis of moderate to severe obstructive sleep apnea and have high levels of agreement with attended polysomnography in a certain subset of patients. Accordingly, this retrospective analysis aimed to assess the technical feasibility of level 3 portable monitoring in hospitalized patients and whether it could provide timely, accurate and, perhaps, diagnostic information to guide the management of sleep-disordered breathing. BACKGROUND: Sleep-disordered breathing (SDB) may impact the course of medical illness among hospitalized patients. Access to testing during hospitalization to assess this may be limited by wait times for laboratory polysomnography. Level 3 portable monitoring (PM) may provide an alternative. OBJECTIVE: To assess the rate of technically adequate studies, diagnostic information obtained and impact on patient management of inpatient PM studies performed for SDB. METHODS: A retrospective review of 114 PM (Embletta, Natus Inc, Canada) records from the past two years was performed. Studies were ordered by pulmonologists, initiated by respiratory therapists and performed unattended on inpatient units. Admitting diagnoses, indication for sleep study, diagnostic information obtained from recordings and change in clinical management subsequent to PM were determined from medical charts. RESULTS: Of 114 studies reviewed, 99 (87%) met predetermined criteria for adequate signal quality and duration. Five studies could not be interpreted due to inadequate data, yielding an overall success rate of 83% (94 of 114). Of 86 studies performed for diagnosis, clinical and PM data supported a new diagnosis of SDB in 55 patients, of which 23 (42%) were started on positive pressure therapy. Thirteen PM studies were performed during SDB treatment. All were technically adequate and six of 13 demonstrated new or persistent SDB. Results from PM testing informed clinical management during hospitalization in 70 (61%) cases. CONCLUSION: Unattended level 3 PM studies are technically feasible in hospitalized patients and may provide information that influences clinical management. PMID:24288699

Substantive-level theory of highly regarded secondary biology teachers' science teaching orientations  

NASA Astrophysics Data System (ADS)

Science teaching orientations, defined as teachers' knowledge and beliefs about the purposes and goals for teaching science, have been identified as a critical component within the proposed pedagogical content knowledge (PCK) model for science teaching. Because of the scarcity of empirical studies in this area, this case study examined the nature and sources of science teaching orientations held by four highly regarded secondary biology teachers. Data sources consisted of transcripts from four interviews, a card-sorting task, and classroom observations. Using a grounded theory framework, inductive data analysis led to the construction of a substantive-level theory for this group of participants. In regard to the nature of science teaching orientations, the use of central and peripheral goals, as well as the means of achieving these goals, was used to represent the complex nature of participants' science teaching orientations. The participants' science teaching orientations included goals related to general schooling, the affective domain, and subject matter, although the latter was not always a central component. In regard to the sources of teaching orientations, participants were strongly influenced by the classroom context and their beliefs about learners and learning; additional influences included prior work experiences, professional development, and time constraints.

Relationship between perceived levels of classroom individualization and science-related attitudes  

NASA Astrophysics Data System (ADS)

Relationships between perceived levels of classroom individualization and science-related attitudes were explored for a sample of 712 junior high school science students. Five dimensions of perceived individualization (personalization, participation, independence, investigation, and differentiation) were measured with the Individualized Classroom Environment Questionnaire (ICEQ), while seven distinct attitudes were measured with the Test of Science-Related Attitudes (TOSRA). Hierarchical regression analyses revealed that the set of individualization variables accounted for a significant increment in end-of-year attitude scores, beyond that attributable to corresponding beginning-of-year attitude scores, for four of the seven attitudes considered. Significant associations between an individual individualization variable and an attitudinal dimension were positive in all cases. The study also provided support for the reliability and validity of the ICEQ and TOSRA and for their general usefulness in science education research.

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

NASA Astrophysics Data System (ADS)

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

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.

Carbon activation diagnostic for tertiary neutron measurements  

NASA Astrophysics Data System (ADS)

The yield of tertiary neutrons with energies greater than 20 MeV has been proposed to determine the high ?R of inertial confinement fusion targets. The activation of carbon is a valuable measurement technique because of its high reaction threshold, the availability of high-purity samples, and relatively low cost. The 12C(n,2n)11C reaction has a Q value of 18.7 MeV, well above the 14.1 MeV primary DT neutron energy. The isotope 11C decays with a half-life of 20.3 min and emits a positron, resulting in the production of two back-to-back, 511 keV gamma rays upon annihilation. The positron decay of 11C is nearly identical to the copper decay used in the activation measurements of 14.1 MeV primary DT yields; therefore, the present copper activation gamma-detection system can be used to detect the tertiary-produced carbon activation. Because the tertiary neutron yield is more than six orders of magnitude lower than primary neutron yield, the carbon activation diagnostic requires ultrapure carbon samples, free from any positron-emitting contamination. In recent years we have developed carbon purification, packaging, and handling procedures that minimize the contamination signal to a level low enough to use carbon activation for tertiary neutron measurements in direct-drive implosion experiments with DT cryogenic targets on OMEGA. Experimental results of contamination measurements in carbon samples performed on high-neutron-yield shots on OMEGA in 2001-2002 will be presented. A concept for implementing a carbon activation system on the National Ignition Facility (NIF) will be discussed.

Enhancing K-12 Ocean Science Education Through Multi-level Partnership  

NASA Astrophysics Data System (ADS)

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

The Arkansas Science Crusade: A descriptive study of the implications for science education reform at the postsecondary level  

NASA Astrophysics Data System (ADS)

The purpose of this study was to evaluate the National Science Foundation-sponsored, constructivist-based course Higher Order Thinking Skills in Science for teachers of grades 5--16 in Arkansas in terms of its impact on post secondary teaching. The course was part of the Arkansas Statewide Systemic Initiative from 1995 to 1998. The participants in the study were 10 science instructors from 9 two-year colleges, 16 instructors from 8 four-year colleges or universities, and one instructor from a private college. Four of the participants were also involved in teaching science education courses. Data were collected from questionnaires and telephone interviews of the 27 participants. They were asked to respond to 26 interview questions to evaluate the effectiveness of the course and its impact on reform of college science teaching. The transcribed interviews were analyzed and responses were tabulated in order to investigate why the participants chose to participate, including their expectations for the course; how the course had changed their views toward the need for reform; how the course had changed the way the participants teach; factors that they considered to hinder reform in science teaching on the college level; and how they would evaluate the overall effectiveness of the course. The findings indicated that there was no difference in responses between participants from two-year or four-year colleges or from the teacher-educators. The majority of the participants reported that the course had resulted in changes in, or reinforcement of, their teaching strategies to include constructivist, hands-on, and/or collaborative group methodologies; use of alternative assessments; and use of calculator-based technology, as well as an opportunity to interact with pre-college teachers. Based upon the interview responses, suggestions for improving the course were discussed. Recommendations for future research included increasing the sample size, especially to include more teacher-educators, and evaluating the effects of the course on the attitudes and achievement of the students of the participants.

Tertiary climatic fluctuations and methods of analysis of tertiary floras  

USGS Publications Warehouse

On theoretical grounds, an analysis of the physiognomy of a Tertiary leaf assemblage is more direct and reliable than a circuitous floristic analysis in assigning thermal regimes to fossil assemblages. Using primarily foliar physiognomy and secondarily floristic composition, it can be shown that: (1) some middle latitude Tertiary assemblages probably lived under meteoroligically tropical climates; (2) a major and rapid climatic deterioration occurred in the Oligocene; and (3) a major climatic fluctuation probably occurred in the Late Eocene. These analyses thus substantiate the conclusions of several other paleobotanists regarding climatic fluctuations. Recent criticisms of these analyses are shown to be invalid and to be based largely on misinterpretations. ?? 1971.

Science education in the Republic of Ireland: At first and second levels  

NASA Astrophysics Data System (ADS)

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

Pricing, taxation for tertiary projects  

SciTech Connect

The difficulty of establishing the basis for tax treatment of a barrel of oil under the 1980 Excise Tax Act (Windfall) is discussed. The sales price of the oil is governed by the US Emergency Petroleum Allocation Act of 1973, as amended, and Department of Energy (DOE) regulations. Pricing categories may not be the same for use under the Tax Act. Several restrictions and burdens of defining and implementing the tax law are cited, concluding that the incremental tertiary decontrol provisions are impractical for most producers and that stripper properties and newly discovered reservoirs appear to be more advantageous for application of tertiary methods of production.

Multiple-choice exams: an obstacle for higher-level thinking in introductory science classes.  

PubMed

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

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.

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

NASA Astrophysics Data System (ADS)

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

Tertiary carbonate reservoirs in Indonesia  

SciTech Connect

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

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.

Exposure to methyl tertiary-butyl ether from oxygenated gasoline in Stamford, Connecticut.  

PubMed

In 1993, state health officials in Connecticut invited the Centers for Disease Control and Prevention (CDC) to assist in an investigation of exposure to methyl tertiary-butyl ether in oxygenated gasoline in Stamford, Connecticut. Venous blood samples were collected from 14 commuters and from 30 other persons who worked in the vicinity of traffic or automobiles, and the samples were analyzed for methyl tertiary-butyl ether, tertiary-butyl alcohol, benzene, m-/p-xylene, o-xylene, and toluene. The highest levels of methyl tertiary-butyl ether in blood were measured among gasoline service station attendants (median = 15 micrograms/l, range = 7.6-28.9 micrograms/l). Blood levels of methyl tertiary-butyl ether were highly variable among persons who worked in car-repair shops (median = 1.73 micrograms/l, range = 0.17-36.7 micrograms/l) and were generally lowest among commuters (median = 0.11 micrograms/l, range = < 0.05-2.60 micrograms/l). Blood levels of methyl tertiary-butyl ether were correlated strongly with personal-breathing-zone samples of methyl tertiary-butyl ether and blood levels of other volatile organic compounds. This exposure information should prove useful to a future risk analysis of this high-volume chemical. PMID:7618951

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.

Participatory System Science: Multi-Level Comprehension Through a Game-like Process  

NASA Astrophysics Data System (ADS)

Participatory System Science: Multi-Level Comprehension Through a Game-like Process We built a time-series game that permits the player to make water management decisions concerning the Skagit River (north-central Washington state) every five years for 60 years. This work was inspired by the integrative efforts of the Skagit Climate Science Consortium and the Climate Impacts Group at the University of Washington. Our principle guiding concepts have been - Construct a reasonable system description with -- wherever possible -- Events / Consequences rendered both visually and in terms of financial impact. - Base the system description on peer reviewed publications - Emphasize both connection and absence of connection between player Actions and subsequent Consequences in the catchment basin. Player choices center around dam flow levels and steps to mitigate negative impacts of sediment transport into the lower (populated) reaches of the Skagit River and into Puget Sound (levees, new dams, estuary restoration, etcetera). With this work we hope to explore scientific results in public awareness by engaging the game Player as a problem solver.

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.

Cretaceous-Tertiary findings, paradigms and problems  

NASA Technical Reports Server (NTRS)

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

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.

An introduction of Tertiary Peritonitis  

PubMed Central

Intraperitoneal infection known as peritonitis is a major killer in the practice of clinical surgery. Tertiary peritonitis (TP) may be defined as intra-abdominal infection that persists or recurs ³48 h following successful and adequate surgical source control. A planned or on-demand relaparotomy after an initial operation is probably most frequent way to diagnose TP, but is a late event to occur. Hence it is desirable to have timely and nonoperative diagnosis of TP after the initial operation and subsequent initiation of an appropriate therapy to reduce the complications and to improve the outcome.

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.

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.

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).

Uranium geochemistry in groundwater from tertiary sediments  

NASA Astrophysics Data System (ADS)

Dissolved U concentrations and activity ratios (ARs) of the U isotopes in the 238U decay series were measured in ground and surface waters as part of an investigation to delineate the water quality in a proposed uranium mining area of northwest Nebraska. In oxidizing groundwaters from 67 wells completed in the Tertiary sediments, increasing U concentrations in the direction of groundwater flow generally were associated with a maturation of the formation water as evidenced by evolutionary trends in major ion character. The increased U levels probably are associated with leaching as shown by the positive correlation between U concentrations and total dissolved solids (TDS) ( r = +0.83). The inverse relationships between TDS and U ARs ( r = -0.73) and U levels and ARs ( r = 0.72) indicate that the decay of excess U-234 is related to maturation of the formation water and to sediment leaching along the flowpath. The data are described by a model which incorporates etching, decay and recoil and suggests that aquifer residence time can be estimated from the TDS level. The levels of soluble U in a reducing uraniferous hydrogeologic unit near Crawford, Nebraska are affected by the proximity of the sample collection to ore. In groundwater samples having similar chemistries (Na-SO 4 + Cl type), similar Ehs, and collected from a close-knit pattern, U concentrations ranged from 0.01 to 2,037 ?g l -1 and ARs ranged from 0.75 to 12.6. This high variability in U levels and ARs is indicative of uranium ore in small areal studies where low ARs almost always are associated with high U concentrations.

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.

Families, economies, cultures, and science achievement in 41 countries: country-, school-, and student-level analyses.  

PubMed

This study examines the links between students' families and science achievement across many countries. Science tests and questionnaire responses of 107,834 fifteen-year-olds in 41 countries were analyzed with multilevel analyses. Students had higher science scores if they were native born, lived with two parents, lived without grandparents, lived with fewer siblings (especially older ones), had more educational resources, had more family involvement, lived in wealthier countries, or lived in countries with more equal distributions of household income. In wealthier countries, family involvement, blended families, and number of siblings showed stronger links to science scores. Science achievement was more strongly linked to family socioeconomic status (SES) and educational resources in more egalitarian cultures and to single parents, family SES, resident grandparents, and birth order in more individualistic cultures. Hence, family constructs were linked to academic achievement in all 41 countries, and the links were stronger in more economically and culturally developed countries. PMID:17874936

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.

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

NASA Astrophysics Data System (ADS)

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

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

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 Relationship Between Computerized Problem-Based Instruction And Students' Cognitive Level of Learning in Secondary Science  

NASA Astrophysics Data System (ADS)

Studies have identified instructional strategies for increasing student achievement but fail to assess the efficacy of these interventions across varying levels of cognitively complex instructional content. Thus, instructional strategies that promote learning for intermediate and higher order cognitive content must be identified. Guided by a conceptual framework proposed by Katzlberger, the purpose of this mixed method quasi-experimental study was to determine the efficacy of computerized problem-based instruction (CPBI) across increasingly complex instructional content. The research questions examined the impact on students' learning resulting from CPBI across low, intermediate and high levels of learning complexity among 308 purposively sampled secondary science students. Paired sample t tests were used to confirm significant pre/post learning gains across experimental conditions and levels of content complexity. The results of independent sample t-tests documented significantly greater gains for the CPBI intervention within the intermediate level of cognitive complexity; however, no statistically significant differences were observed for the student scores within the lower and higher levels of complexity. Qualitative data from a survey administered pre/post intervention were coded to assess differences in preference for, and the perceived value of CPBI. Chi square analyses of the recoded data documented significantly higher perceived preference and value for CBPI within the intervention group. This research study can positively impact social change by informing decision making related to selecting instructional strategies that promote learning at different levels of cognitive complexity within science curriculum.

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

NASA Astrophysics Data System (ADS)

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

An analysis of the relationship between teachers' acquisition of physics content knowledge and their level of science teaching efficacy  

NASA Astrophysics Data System (ADS)

The goal of Project Inquiry, a two-year long multiphase study, was to transform the delivery of science instruction from a traditional, textbook driven delivery approach to a hands-on, minds-on, constructivist approach. Teachers from a midwestern urban school district were trained in constructivism while learning physics concepts and content through guided inquiry instruction in collaborative groups. The objectives aimed to increase teachers' content expertise and science teaching efficacy, as well as to have teachers become better facilitators of learning. Phase two of the three phases of Project Inquiry was the focus of this study. Fifty-seven teachers participated in Phase two, which began with an intense two week summer institute in 1995. A longitudinal time-series (OxOO), quasi-experimental research design was used to investigate the relationship between science teaching efficacy scores and gains in physics content knowledge. The data consisted of: (a) six sets of pre and post physics content knowledge test scores (electricity, magnetism, matter and balance); (b) three sets of STEBI-A (inservice), Science Teaching Efficacy Belief Instrument scores, a pre to post, pre to follow-up, and post to follow-up; and (c) demographic variables that were used as covariates, grade taught, years of experience, and postbaccalaureate training. Using the general linear model with an Alpha level of.05, and testing the hypothesized relationships, results indicated that although there were significant positive gains in content knowledge (p =.000) and science teaching efficacy (p =.000), the overall average gains in physics content knowledge were not predictive of gains in either Personal Science Teaching Efficacy or Science Outcome Expectancy. Post hoc analysis used individual content gain scores, in regression models that included the three covariates: grade taught, years of experience, and post baccalaureate training, to test the relationship between knowledge gains and efficacy gains. A series of interactions between significant content areas and the covariates was also run. Science Teaching Outcome Expectancy and Personal Science Teaching Efficacy showed different relationships with the predictor variables. Though gains in specific content areas were related to gains in Science Teaching Outcome Expectancy and Personal Science Teaching Efficacy, gains in Personal Science Teaching Efficacy were further modified by the covariates. These results may reflect not only a more complex relationship between content knowledge gain and Personal Science Teaching Efficacy but also the complex nature of the construct. Evaluation of the physics content knowledge tests revealed that the tests were not valid for evaluating 35 of the 37 identified learning objectives. Although the data did not render valid results, it does give insights into possible relationships that may exist given a more stringent investigation with a valid instrument to measure content knowledge gains. In addition, this study demonstrated the importance of considering the likelihood of interactions among a given set of variables and the covariates. The findings also suggest the possible value of considering the psychological factors associated with the change process when planning professional development programs.

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.

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.

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.

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

NASA Astrophysics Data System (ADS)

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

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

NASA Astrophysics Data System (ADS)

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

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.

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

NASA Astrophysics Data System (ADS)

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

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.

Learning in a personal context: Levels of choice in a free choice learning environment in science and natural history museums  

NASA Astrophysics Data System (ADS)

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

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.

Purification of dialkylzinc precursors using tertiary amine ligands  

NASA Astrophysics Data System (ADS)

Tertiary amines are useful for the production of high purity low-oxygen content R2Zn dopant sources. Trace oxygen levels in Me2Zn are significantly reduced by formation of the Me2Zn.NEt3 adduct, which is a more controllable and reproducible source than Me2Zn/H2 gas mixtures. Me2Zn and Et2Zn form 2?1 adducts with the macrocyclic tertiary amines 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane (N4-aza crown) and 1,4,7,10,13,16-hexamethyl-1,4,7,10,13,16-hexaazacyclooctadecane (N6-aza crown), and the structure of these compounds has been determined by single crystal x-ray crystallography. Mild thermal dissociation of R2Zn-aza crown adducts yields base-free R2Zn, giving them potential applications in the purification of Me2Zn and Et2Zn dopant sources for the MOVPE of III-V materials.

Quantitative characterization of protein tertiary motifs.  

PubMed

A quantitative feature-vector representation/model of tertiary structural motifs of proteins is presented. Multiclass logistic regression and a probabilistic neural network were employed to apply this representation to large data sets in order to classify them into major families of distinct motif types (including those of functional importance) with high statistical confidence. Scatter plots of random samples of these motifs were obtained through two-dimensional transformation of the feature vector by metric MDS (multidimensional scaling). The plots showed distinct clusters and shapes for different families and demonstrated the relevance and importance of the proposed quantitative feature-vector representation for characterizing protein tertiary structural motifs. The relative importance of the features was analyzed. The scope of the present work to investigate Nature's prioritization and optimization of functional motif structures is highlighted.

Science PhD career preferences: levels, changes, and advisor encouragement.  

PubMed

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.

Cooperative tertiary interaction network guides RNA folding  

PubMed Central

SUMMARY Non-coding RNAs form unique three-dimensional structures, which perform many biochemical and 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. 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 native state stability. Instead, formation of core and peripheral structural motifs are cooperatively linked in near-native folding intermediates, and this cooperativity depends on the native topology of the ribozyme. The emergence of a cooperative interaction network at an early stage of folding suppresses non-native structures and makes the search for the native state more efficient. We suggest that cooperativity in non-coding RNAs arose from natural selection of architectures that promote a unique fold despite a rugged energy landscape. PMID:22500801

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.

Barriers of hydrogen abstraction from primary, secondary, and tertiary alkane sites by O(3P).  

PubMed

We present an extensive study of the barriers of hydrogen abstraction from primary, secondary, and tertiary sites of acyclic alkanes by ground-state oxygen atoms. Our studies include the characterization of the lowest-energy transition states of the O(3P) reactions with methane, ethane, propane, isobutane, and isopentane using high-level ab initio methods. The order of the calculated barriers heights is primary > secondary > tertiary, in agreement with the trends gleaned from kinetic measurements. Analysis of the transition-state geometry reveals a shift toward more reagents-like structures in the primary --> secondary --> tertiary sequence, which concurs with the expectation from Hammond's postulate. Using the ab initio data, we calculate thermal rate constants via transition-state theory. Our highest-level calculations indicate that the room-temperature relative reactivities of primary, secondary, and tertiary alkane sites in hydrogen-abstraction reactions by ground-state oxygen atoms are 1, 29, and 422, respectively. These results are used to interpret recent experiments on the reactions of O(3P) with liquid alkanes. PMID:17914781

Organizing Science Popularization and Teacher Training Workshops : A Nigerian Experience  

NASA Astrophysics Data System (ADS)

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

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.

Stereoinversion of tertiary alcohols to tertiary-alkyl isonitriles and amines.  

PubMed

The SN2 reaction (bimolecular nucleophilic substitution) is a well-known chemical transformation that can be used to join two smaller molecules together into a larger molecule or to exchange one functional group for another. The SN2 reaction proceeds in a very predictable manner: substitution occurs with inversion of stereochemistry, resulting from the 'backside attack' of the electrophilic carbon by the nucleophile. A significant limitation of the SN2 reaction is its intolerance for tertiary carbon atoms: whereas primary and secondary alcohols are viable precursor substrates, tertiary alcohols and their derivatives usually either fail to react or produce stereochemical mixtures of products. Here we report the stereochemical inversion of chiral tertiary alcohols with a nitrogenous nucleophile facilitated by a Lewis-acid-catalysed solvolysis. The method is chemoselective against secondary and primary alcohols, thereby complementing the selectivity of the SN2 reaction. Furthermore, this method for carbon-nitrogen bond formation mimics a putative biosynthetic step in the synthesis of marine terpenoids and enables their preparation from the corresponding terrestrial terpenes. We expect that the general attributes of the methodology will allow chiral tertiary alcohols to be considered viable substrates for stereoinversion reactions. PMID:24025839

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.

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

NASA Astrophysics Data System (ADS)

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

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.

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.

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.

'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.

Evaluation of Health Literacy Status Among Patients in a Tertiary Care Hospital in Coastal Karnataka, India  

PubMed Central

Introduction: People with limited health literacy are more likely to make medication errors, and they have less health knowledge, worse health status, more hospitalizations, and higher healthcare costs than people with adequate literacy. The objective of this study is to assess the health literacy status among patients who are able to read and understand English attending a tertiary care hospital by using Rapid Estimate of Adult Literacy in Medicine [REALM] technique and to compare the health literacy levels to educational status and other baseline characteristics. Material and Methods: A widely used word recognition method [REALM] was used to assess the HL status of 200 patients attending a tertiary care hospital in Southern India. The number of correctly pronounced words was used to assign a grade-equivalent reading level. Scores 0 to 44 indicate reading skills at or below the 6th grade level, scores from 45 to 60 represent skills at the 7th or 8th grade level, and scores above 60 indicate skills at the high-school level or higher. Results: HL status was found below adequate level in more than 50% of the patients. Younger age group showed better HL scores compared to those aged more than 25 years. General education level or the medium of education does not truly reflect HL levels as brought out in the study. Even those with postgraduate qualification had poor HL skills. Conclusion: The study was carried out to find out the HL levels among patients attending a tertiary care hospital. It was assumed that the general education levels may not reflect true HL status. In view of the results of this study it can be concluded that patient’s HL skills should not be taken for granted and adequate attention should be paid in educating and briefing patients whenever patients are required to interpret and understand health care related documents.

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.

A comparative study of traditional lecture methods and interactive lecture methods in introductory geology courses for non-science majors at the college level  

NASA Astrophysics Data System (ADS)

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

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.

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 relationship of attitudes toward science, cognitive style, and self-concept to achievement in chemistry at the secondary school level  

NASA Astrophysics Data System (ADS)

There is currently a crisis in science education in the United States. This statement is based on the National Science Foundation's report stating that the nation's students, on average, still rank near the bottom in science and math achievement internationally. This crisis is the background of the problem for this study. This investigation studied learner variables that were thought to play a role in teaching chemistry at the secondary school level, and related them to achievement in the chemistry classroom. Among these, cognitive style (field dependence/independence), attitudes toward science, and self-concept had been given considerable attention by researchers in recent years. These variables were related to different competencies that could be used to measure the various types of achievement in the chemistry classroom at the secondary school level. These different competencies were called academic, laboratory, and problem solving achievement. Each of these chemistry achievement components may be related to a different set of learner variables, and the main purpose of this study was to investigate the nature of these relationships. Three instruments to determine attitudes toward science, cognitive style, and self-concept were used for data collection. Teacher grades were used to determine chemistry achievement for each student. Research questions were analyzed using Pearson Product Moment Correlation Coefficients and t-tests. Results indicated that field independence was significantly correlated with problem solving, academic, and laboratory achievement. Educational researchers should therefore investigate how to teach students to be more field independent so they can achieve at higher levels in chemistry. It was also true that better attitudes toward the social benefits and problems that accompany scientific progress were significantly correlated with higher achievement on all three academic measures in chemistry. This suggests that educational researchers should investigate how students might be guided to manifest more favorable attitudes toward science so they will achieve at higher levels in chemistry. An overall theme that emerged from this study was that findings refuted the idea that female students believed that science was for males only and was an inappropriate and unfeminine activity. This was true because when the means of males and females were compared on the three measures of chemistry achievement, there was no statistically significant difference between them on problem solving or academic achievement. However, females were significantly better in laboratory achievement.

RNA tertiary structure analysis by 2'-hydroxyl molecular interference.  

PubMed

We introduce a melded chemical and computational approach for probing and modeling higher-order intramolecular tertiary interactions in RNA. 2'-Hydroxyl molecular interference (HMX) identifies nucleotides in highly packed regions of an RNA by exploiting the ability of bulky adducts at the 2'-hydroxyl position to disrupt overall RNA structure. HMX was found to be exceptionally selective for quantitative detection of higher-order and tertiary interactions. When incorporated as experimental constraints in discrete molecular dynamics simulations, HMX information yielded accurate three-dimensional models, emphasizing the power of molecular interference to guide RNA tertiary structure analysis and fold refinement. In the case of a large, multidomain RNA, the Tetrahymena group I intron, HMX identified multiple distinct sets of tertiary structure interaction groups in a single, concise experiment. PMID:25341083

Genome evolution of a tertiary dinoflagellate plastid.  

PubMed

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.

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.

Carbonate reservoirs at the Mesozoic-Tertiary unconformity, northeast Spain  

SciTech Connect

Carbonates at the Mesozoic-Tertiary unconformity in northeast Spain show four types/stages of evolution of reservoir properties: karstification, coastal reworking, Miocene organic buildups, and Pliocene burial. Subaerial exposure during Paleogene-early Miocene rifting developed a complex fracture-controlled paleokrast facies, showing up to three evolution levels with well-developed cavern and vuggy porosity (1). During the Miocene, the paleokrast profile was intensively reworked into a variety of breccias, conglomerates, and calcarenites in both alluvial and coastal depositional settings. Gravitational displacement of largely karstified hillsides was common. These reworked paleokarst deposits (2) present excellent reservoir properties. The Miocene formations onlap the karstified Mesozoic and the reworked facies; these formations include coral reefs and foramalgal buildups (3) with primary and secondary porosity. Finally, a late fracture event (attributed to the Pliocene) affected the buried and lithified paleokarst deposits and lower-middle Miocene formations (4). This fracture event is associated with vuggy corrosion, dolomitization, ore mineralization, and leaching of Mesozoic to middle Miocene carbonates. Several horizons with chalky microporosity are also tentatively related to this Pliocene event. These four phases of reservoir evolution are also recognized in northern Morocco and southern Italy.

Role of tertiary structures on the Root effect in fish hemoglobins.  

PubMed

Many fish hemoglobins exhibit a marked dependence of oxygen affinity and cooperativity on proton concentration, called Root effect. Both tertiary and quaternary effects have been evoked to explain the allosteric regulation brought about by protons in fish hemoglobins. However, no general rules have emerged so far. We carried out a complementary crystallographic and microspectroscopic characterization of ligand binding to crystals of deoxy-hemoglobin from the Antarctic fish Trematomus bernacchii (HbTb) at pH6.2 and pH8.4. At low pH ligation has negligible structural effects, correlating with low affinity and absence of cooperativity in oxygen binding. At high pH, ligation causes significant changes at the tertiary structural level, while preserving structural markers of the T state. These changes mainly consist in a marked displacement of the position of the switch region CD corner towards an R-like position. The functional data on T-state crystals validate the relevance of the crystallographic observations, revealing that, differently from mammalian Hbs, in HbTb a significant degree of cooperativity in oxygen binding is due to tertiary conformational changes, in the absence of the T-R quaternary transition. This article is part of a Special Issue entitled: Oxygen Binding and Sensing Proteins. PMID:23376186

How is Science Learning Assessed at the Postsecondary Level? Assessment and Grading Practices in College Biology, Chemistry and Physics  

NASA Astrophysics Data System (ADS)

The role of assessment in higher education is gaining importance as accountability requirements intensify and as assessments are increasingly recognized as having potential to improve teaching and learning. During the last two decades, educators have begun implementing a wider variety of assessment types including alternative and student-centered assessment practices. However, few research studies have examined the extent that college science faculty use such practices. This large-scale descriptive study utilized a nationally representative sample of higher education faculty from the US Department of Education to examine the assessment and grading practices of college science faculty from 2 and 4-year higher education institutions. When data was disaggregated by science discipline, statistically significant differences were found among physics, chemistry and biology faculty's assessment and grading practices. Biology faculty used a larger repertoire of assessment types overall, and used assessments that have potential to enhance the learning process more than chemistry and physics faculty. Physics and chemistry faculty graded on a curve more often and used competency-grading practices less often than biology faculty. Assessment practices that could be considered formative with potential to promote student learning appear to be underutilized by all science faculty.

The effect of retesting on end-of-semester performance in high school chemistry at three levels of previous science achievement  

NASA Astrophysics Data System (ADS)

To determine the effect of retesting on student learning in chemistry, three questions were addressed by means of a 3 × 2 (achievement level X treatment) factorial design: (1) Does retesting affect differently the end-of-semester mastery of course objectives of students who are grouped according to their previous achievement in science? (2) Do students who are given an opportunity to take retests merely delay their studying and perform at a lower level on initial tests than nonretested students? (3) Is the procrastination of retested students (if it exists) affected by their achievement level? The results showed that for one of four units low ability students who were retested demonstrated greater learning gains than low ability students who were not retested, and that procrastination, if it was present, did not have significant effects on student learning at any achievement level. Results were discussed in terms of the students' room for improvement, motivation to improve, and ability to improve.

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.

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.

An investigation of components of the studio model and supplemental online materials, on student achievement and attitudes in science at the high school level  

NASA Astrophysics Data System (ADS)

With the increase of the student population, and meeting the demands driven by society public schools are scrambling to find ways to enhance learning and improve student achievement (Lee, 1993). Schools are examining and investing more time in the development of new approaches needed to strengthen, reach, and spark the interest of students both in and outside of classroom. One direction public schools are taking is to incorporate technology and more peer-directed group activities into instruction. Technological advancements today have enhanced the learning process by providing alternatives that stimulate the interest of the learner. Having these technology options available, allows the student to move at his or her own pace giving them time to reflect and make connections between what they already know and what they have learned in class. Using the conceptual framework of the Studio Model, which was developed in the 1980s at Rensselaer Polytechnic Institute for undergraduate and graduate level science courses, this study investigated the nature and extent to which the components in the Studio Model (cooperative collaboration and online materials) can be extended to the high school science level. A quasi-experimental, pretest-posttest design was selected for this study. Classes were randomly assigned to one of the four treatment groups, an experimental "Studio Model" condition in which students worked cooperatively and had access to online materials, an "Augmented Only" condition in which students had access to online materials only, a "Cooperative Only" condition in which students worked in cooperative groups only, and a "Control" condition in which students neither had access to online materials nor worked cooperatively. The data was collected for this study using 77 ninth-grade students studying Earth Science. Students were trained for a period of 20 weeks in the procedures of their particular treatment. To determine the effects of each treatment on student achievement three separate tests (aptitude, pretest and posttest) were administered over a seven-month period. Twelve interviews were also carried out at the end of the eight weeks to determine whether the students' attitude about science had changed since the beginning of the year. This study provides evidence supporting the usage of the Studio Model to raise student achievement and student attitudes about science at the high school level.

Macro-level approaches to HIV prevention among ethnic minority youth: state of the science, opportunities, and challenges.  

PubMed

The HIV epidemic continues to disproportionately affect ethnic minority youth. These disconcerting health disparities indicate that although existing HIV preventive strategies for ethnic minority youth have been efficacious, they have not significantly reduced the impact of the epidemic in this population. Macro-level interventions, such as structural or policy interventions, have the potential to impact the HIV epidemic at a population level, and thus reduce the HIV health disparities that exist among ethnic minority youth and other segments of the U.S. population. This article calls for a paradigm shift to develop, evaluate, and disseminate interventions that target upstream/macro-level factors or that, at a minimum, integrate both a macro and individual level perspective. The article also discusses the challenges in developing and evaluating such interventions. Psychologists and other behavioral scientists can play a critical role in reducing the impact of HIV on ethnic minority youth by integrating macro-level approaches to future HIV prevention strategies.

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.

Protein-Like Tertiary Folding Behavior from Heterogeneous Backbones  

PubMed Central

Due to the vital roles proteins play in life, much effort has been invested in their mimicry by synthetic agents. One approach to this goal is to design unnatural backbone oligomers (“foldamers”) that fold like natural peptides. Despite success in secondary structure mimicry by such species, protein-like tertiary folds remain elusive. A fundamental challenge underlying this task is the design of a sequence of side chains that will specify a complex tertiary folding pattern on an unnatural backbone. We report here a sequence-based approach to convert a natural protein with a compact tertiary fold to an analogue with a backbone composed of ?20% unnatural building blocks but similar folding behavior as the parent protein.

Sorption of platinum metals by a polymeric tertiary amine  

SciTech Connect

The surface compounds formed upon the sorption of palladium(II) and iridium(IV) by a polymeric tertiary amine from hydrochloric acid solutions at room temperature have been investigated by electronic spectroscopy. It has been established that the sorption takes place in two stages with the formation of ionic associates and coordination compounds with a mixed coordination sphere (Cl, N). The relationship between these stages is determined primarily by the nature of the metal. Some similarity between the mechanisms of the sorption and extraction processes in the recovery of platinum metals by monomeric (extractants) and polymeric (sorbents) tertiary amines has been noted.

Discovery of Tertiary Sulfonamides as Potent Liver X Receptor Antagonists  

SciTech Connect

Tertiary sulfonamides were identified in a HTS as dual liver X receptor (LXR, NR1H2, and NR1H3) ligands, and the binding affinity of the series was increased through iterative analogue synthesis. A ligand-bound cocrystal structure was determined which elucidated key interactions for high binding affinity. Further characterization of the tertiary sulfonamide series led to the identification of high affinity LXR antagonists. GSK2033 (17) is the first potent cell-active LXR antagonist described to date. 17 may be a useful chemical probe to explore the cell biology of this orphan nuclear receptor.

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.

The global Cretaceous-Tertiary fire: Biomass or fossil carbon  

NASA Technical Reports Server (NTRS)

The global soot layer at the K-T boundary indicates a major fire triggered by meteorite impact. However, it is not clear whether the principal fuel was biomass or fossil carbon. Forests are favored by delta value of C-13, which is close to the average for trees, but the total amount of elemental C is approximately 10 percent of the present living carbon, and thus requires very efficient conversion to soot. The PAH was analyzed at Woodside Creek, in the hope of finding a diagnostic molecular marker. A promising candidate is 1-methyl-7-isopropyl phenanthrene (retene,), which is probably derived by low temperature degradation of abietic acid. Unlike other PAH that form by pyrosynthesis at higher temperatures, retene has retained the characteristic side chains of its parent molecule. A total of 11 PAH compounds were identified in the boundary clay. Retene is present in substantial abundance. The identification was confirmed by analysis of a retene standard. Retene is characteristic of the combustion of resinous higher plants. Its formation depends on both temperature and oxygen access, and is apparently highest in oxygen-poor fires. Such fires would also produce soot more efficiently which may explain the high soot abundance. The relatively high level of coronene is not typical of a wood combustion source, however, though it can be produced during high temperature pyrolysis of methane, and presumably other H, C-containing materials. This would require large, hot, low O2 zones, which may occur only in very large fires. The presence of retene indicates that biomass was a significant fuel source for the soot at the Cretaceous-Tertiary boundary. The total amount of elemental C produced requires a greater than 3 percent soot yield, which is higher than typically observed for wildfires. However, retene and presumably coronene imply limited access of O2 and hence high soot yield.

The Hyper-Commons: how open science prizes can expand and level the medical research playing field.  

PubMed

The largest industry in America is increasingly incapable of serving its customers. Over-fencing of the information commons has led to unaffordable medicine, for want of which millions of Americans and people around the world go without lifesaving treatments. Eliminating patent distribution exclusivity altogether, however, is not feasible, given the entrenched nature of the health-care industry. This paper proposes a program of voluntary Open Science Prizes that would draw large numbers of new players, who would in turn produce much new medical innovation, provide academic priority recognition, and develop a growing body of patent-beating prior art that would serve as public domain firewalls on a new supranational Hyper-Commons.

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.

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.

Exploring Omani pre-service science teachers' imagination at the microscopic level in chemistry, and their use of the particulate nature of matter in their explanations  

NASA Astrophysics Data System (ADS)

The purpose of this study was to explore learners' imagination at the microscopic level of matter and their use of the Particulate Theory of Matter. As for the imagination component, twenty-two Omani pre-service science teachers were encouraged individually during a guided imagery session to construct images for the interactions among micro-species such as molecules, atoms, and electrons. The findings determined several factors that contributed in shaping participants' mental images at the microscopic level of mater. Some of these factors related to previous experience, mental abilities, and the nature of microscopic interactions. This study argued that participants lacked a homogeneous and reliable mental model of the atom that was required to carry out advanced cognitive processes for mental exploration of chemical phenomena. In addition, the imagination of three female participants was further analyzed to explore their information processing of the microscopic imagined actions. They were chosen because they created different atomic models from each other. These models were: space-filling balls model, humanized model, and Latin characters model. Each participant's created mental images of microscopic actions were discussed based on her atomic model. The findings suggested that the nature of each participant's model partially influenced her microscopic imagined actions. The second component of this study tested the effect of different textual, pictorial, and reflective cues on participants' use of the microscopic level, the accuracy of their explanations and the originality of their inventions. The cues, either microscopic or macroscopic, were administered in a researcher-designed test to 152 Omani pre-service science teachers. The findings revealed that students did not use the PTM theory unless they were cued. The particulate level of the explanations of those who received a microscopic guided imagery textual cue was significantly higher than those who received a macroscopic cue. Also, the accuracy of explanations of participants who received a microscopic pictorial cue was significantly higher than those who received the macroscopic picture. In addition, a microscopic reflective cue improved the microscopic level of 43 participants' explanations. However, the microscopic textual cue did not have a significant effect on the accuracy of explanations, or on the originality of inventions.

ENVIROSUITE: USING STATE-OF-THE-ART SYNCHROTRON TECHNIQUES TO UNDERSTAND ENVIRONMENTAL REMEDIATION SCIENCE ISSUES AT THE MOLECULAR LEVEL.  

SciTech Connect

Although DOE's Environmental Management program has made steady progress in cleaning up environmental legacies throughout the DOE complex, there are still significant remediation issues that remain to be solved. For example, DOE faces difficult challenges related to potential mobilization of radionuclides (e.g., actinides) and other hazardous contaminants in soils, removal and final treatment of high-level waste and residuals from leaking tanks, and the long-term stewardship of remediated sites and engineered disposal facilities, to name just a few. In some cases, new technologies and technology applications will be required based on current engineering expertise. In others, however, basic scientific research is needed to understand the mechanisms of how contaminants behave under specific conditions and how they interact with the environment, from which new engineering solutions can emerge. At Brookhaven National Laboratory (BNL) and Stony Brook University, scientists have teamed to use state-of-the-art synchrotron techniques to help understand the basic interactions of contaminants in the environment. Much of this work is conducted at the BNL National Synchrotron Light Source (NSLS), which is a user facility that provides high energy X-ray and ultraviolet photon beams to facilitate the examination of contaminants and materials at the molecular level. These studies allow us to determine how chemical speciation and structure control important parameters such as solubility, which in turn drive critical performance characteristics such as leaching. In one study for example, we are examining the effects of microbial activity on actinide contaminants under conditions anticipated at the Waste Isolation Pilot Plant. One possible outcome of this research is the identification of specific microbes that can trap uranium or other contaminants within the intracellular structure and help mitigate mobility. In another study, we are exploring the interaction of contaminants with soil and plant roots to better understand the mechanisms responsible for uptake. This effort will lead to improvements in phytoremediation, an innovative and cost-effective approach to the cleanup of large volumes of soil with low concentrations of contaminants. In a third effort, we are investigating molecular interactions of contaminants in high-level waste tanks with potential grouting materials for remediation of the West Valley, NY site to assess their suitability and long-term performance.

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

Impact of ozonation on ecotoxicity and endocrine activity of tertiary treated wastewater effluent.  

PubMed

Tertiary wastewater treatment plant effluent before and after ozonation (0.6-1.1g O?/g DOC) was tested for aquatic ecotoxicity in a battery of standardised microbioassays with green algae, daphnids, and zebrafish eggs. In addition, unconjugated estrogen and 17?-hydroxyandrogen immunoreactive substances were quantified by means of enzyme immunoassays, and endocrine effects were analysed in a 21-day fish screening assay with adult male and female medaka (Oryzias latipes). Ozonation decreased estrogen-immunoreactivity by 97.7±1.2% and, to a lesser extent, androgen-immunoreactivity by 56.3±16.5%. None of the short-term exposure ecotoxicity tests revealed any adverse effects of the tertiary effluent, neither before nor after the ozonation step. Similarly in the fish screening assay, reproductive fitness parameters showed no effects attributed to micropollutants, and no detrimental effects of the effluents were observed. Based on the presented screening, ozonation effectively reduced steroid hormone levels in the wastewater treatment plant effluent without increasing the effluent's ecotoxicity. PMID:22551818

Cryptococcal Meningitis in Patients with or without Human Immunodeficiency Virus: Experience in a Tertiary Hospital  

PubMed Central

Purpose Cryptococcal meningitis is a relatively common opportunistic infection in human immunodeficiency virus (HIV) patients and it can frequently occur in immunocompetent hosts without any apparent underlying disease. Nevertheless, little is known about cyptococcal meningitis in the Korean population. The purpose of this study was to evaluate the clinical features and initial laboratory findings of cryptococcal meningitis in patients with and without HIV at a tertiary care teaching hospital. Materials and Methods We performed a retrospective study at a tertiary care teaching hospital from January 2001 to December 2009. Eleven HIV positive patients and nine HIV negative patients were included. Results The most common symptoms were headache and fever in cryptococcal meningitis, and diabetic mellitus, end stage renal disease and liver cirrhosis were the main associated conditions in patients without HIV. Patients with HIV showed lower peripheral CD4+ cell counts (median: 9, range: 1-107) and a higher burden of cryptococcus than patients without HIV. There were no statistically significant differences in serum CRP level and other cerebrospinal fluid parameters between patients with HIV and without HIV. The in-hospital mortality was 10%, and recurrence of cyptococcal meningitis was observed in 3 patients with HIV and this occurred within 5 months of the first episode. Conclusion Cryptococcal meningitis is fatal without treatment, therefore, rapid recognition of symptoms such as fever and headache and diagnosis is required to decrease the mortality. Recurrence of meningitis after treatment should carefully be followed up, especially in advanced HIV patients. PMID:21488192

Differences in eighth grade science student and teacher perceptions of students' level of input into academic planning and decision making  

NASA Astrophysics Data System (ADS)

Teachers are expected to improve their planning, instruction, and assessment as they progress through their career. An important component to teachers knowing what to modify in their teaching style is being able to solicit meaningful feedback from students. This mixed-methods study was conducted to provide teachers with a quantitative method to collect data about their teaching using the Constructivist Learning Environment Survey (CLES). Phase 1 allowed students to provide anonymous feedback to their teachers that the teachers could later reflect upon in conjunction with the students' other feedback. Using measures of central tendencies, it was determined that of the five categories of the CLES the area of student negotiation was statistically different from the other categories. While eight teachers had sufficient (n>10) student data to be invited to participate in Phase 2, only five of the teachers choose to participate in a semi-structured interview to further examine the potential differences between teacher and student perception of student negotiation with the curriculum, instruction and assessment that occurs in the classroom. Coding the interview transcripts led to three categories: 1) teaching style (with themes including curriculum, instruction, and assessment, and sub themes of teacher centered and student centered); 2) external pressures (with themes of standards , standardized tests, and socioeconomic conditions); 3) effectiveness of student negotiation (with themes of positive effect or no effect on motivation). The five teachers who participated in Phase 2 had varying levels of awareness and willingness to adjust their classroom curriculum, instruction, and assessment to include student negotiation. All but one teacher, however, saw the value in increasing student negotiation in the classroom and desired to continue to change their teaching to include more student negotiation.

Continuity of care: the orthopaedic nurse practitioner in tertiary care.  

PubMed

Since 1965 registered nurses have been educated to perform expanded functions in primary health care. The nurse provider role evolved from a shortage of primary health care providers. "Nurse practitioners" were needed to increase access to health care in urban and rural areas of the country that lacked the necessary number of providers to give quality patient care. Until recently, the majority of nurse practitioners have continued in the traditional primary care role, practicing in clinics, private physician offices, and on an independent basis. However, many factors now provide the impetus to have nurse practitioners develop tertiary care practices within the nation's acute care hospitals. This article describes the development and implementation of an orthopaedic collaborative practice in tertiary care. PMID:8233580

Homogeneous and Heterogeneous Tertiary Structure Ensembles of Amyloid-? Peptides  

PubMed Central

The interplay of modern molecular simulation and high-quality nuclear magnetic resonance (NMR) experiments has reached a fruitful stage for quantitative characterization of structural ensembles of disordered peptides. Amyloid-? 1–42 (A?42), the primary peptide associated with Alzheimer’s disease, and fragments such as A?21–30 are both classified as intrinsically disordered peptides (IDPs). We use a variety of NMR observables to validate de novo molecular dynamics simulations in explicit water to characterize the tertiary structure ensemble of A?42 and A?21–30 from the perspective of their classification as IDPs. Unlike the A?21–30 fragment that conforms to expectations of an IDP that is primarily extended, we find that A?42 samples conformations reflecting all possible secondary structure categories and spans the range of IDP classifications from collapsed structured states to highly extended conformations, making it an IDP with a far more heterogeneous tertiary ensemble.

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.

Mupirocin resistance in clinical isolates of staphylococci in a tertiary care centre in south India.  

PubMed

The present study was carried out to determine the rates of high-level and low-level mupirocin resistance in Staphylococcus spp. (MuH and MuL) in southern India. A prospective study was carried out on Staphylococcus spp. isolated for a period of three months in the microbiology laboratory of an 800-bedded tertiary care hospital. One hundred sixty-seven non-duplicate Staphylococcus spp. isolated from different specimens were tested for mupirocin susceptibility using 5 and 200 ?g discs and by agar dilution. Rates of MuH were found to be two percent in methicillin-resistant Staphylococcus aureus (MRSA) and 28% in methicillin-resistant coagulase-negative Staphylococcus spp. (MRCoNS). MuL strains may be still treated with mupirocin, while MuH strains require other treatment options for eradication, making prior screening and differentiation important. PMID:20966573

Two major tertiary folding transitions of the Tetrahymena catalytic RNA.  

PubMed Central

The L-21 Tetrahymena ribozyme, an RNA molecule with sequence-specific endoribonuclease activity derived from a self-splicing group I intron, provides a model system for studying the RNA folding problem. A 160 nucleotide, independently folding domain of tertiary structure (the P4-P6 domain) comprises about half of the ribozyme. We now apply Fe(II)-EDTA cleavage to mutants of the ribozyme to explore the role of individual structural elements in tertiary folding of the RNA at equilibrium. Deletion of peripheral elements near the 3' end of the ribozyme destabilizes a region of the catalytic core (P3-P7) without altering the folding of the P4-P6 domain. Three different mutations within the P4-P6 domain that destabilize its folding also shift the folding of the P3-P7 region of the catalytic core to higher MgCl2 concentrations. We conclude that the role of the extended P4-P6 domain and of the 3'-terminal peripheral elements is at least in part to stabilize the catalytic core. The organization of RNA into independently folding domains of tertiary structure may be common in large RNAs, including ribosomal RNAs. Furthermore, the observation of domain-domain interactions in a catalytic RNA supports the feasibility of a primitive spliceosome without any proteins. Images PMID:8013466

Tertiary amines enhance reactions of organic contaminants with aqueous chlorine.  

PubMed

Through various anthropogenic inputs, tertiary amines can readily contaminate wastewater and drinking water sources and can form chlorammonium species (R(3)N(+)-Cl) during aqueous chlorine disinfection. This study investigated the less understood concept that these chlorammonium species can potentially enhance organic contaminant loss and increase disinfection byproduct formation to a greater extent than aqueous chlorine. Tertiary amines' effectiveness was highly dependent on amine structure as trimethylamine (TMA) and 4-morpholineethanesulfonic acid (MES) enhanced organic contaminant loss, while others (nitrilotriacetic acid (NTA) and creatinine (CRE)) were ineffective. MES addition up to 25 ?M led to increased organic contaminant chlorination by up to three orders of magnitude while observing pseudo-first order kinetic behavior and a linear amine dose response. TMA addition up to 0.5 ?M accelerated organic contaminant chlorination by almost two orders of magnitude, but occasionally deviated from pseudo-first order kinetics with incomplete organic contaminant degradation and a non-linear amine dose response - a result linked to TMA's rapid auto-decomposition over time. Byproduct formation was identical with and without amine addition, and thus the chlorination mechanisms are likely similar to aqueous chlorine. Results from this study improve the mechanistic understanding behind tertiary amine-enhanced chlorination. PMID:21968217

A Comparative Study of Treatment-seeking Inhalant Abusers Across Two Cohorts from a Tertiary Care Center in India  

PubMed Central

Context: Inhalant abuse is the deliberate inhalation of a volatile substance to achieve an altered mental state. Inhalants continue to be a poorly recognizable risk for morbidity and mortality globally. Aims: The current study explores the pattern of inhalant abuse across different year groups among the individuals seeking treatment form the de-addiction center of a tertiary care hospital. Settings and Design: The study was conducted at a tertiary care multi-specialty hospital. Materials and Methods: The current study is a chart review of the cases with inhalant abuse/dependence presenting to the clinic. All the treatment records of the de-addiction clinic were reviewed and information was gathered regarding patients with inhalant abuse/dependence. The comparisons have been made across two different year groups. The two groups were compared for various continuous and categorical variables using the independent sample t test and ?2 test/Fisher's exact test, respectively. The level of statistical significance was kept at P<0.05 for all these tests. Results: The two study groups have been found comparable for various socio-demographic and inhalant use patterns. Conclusions: The findings of the current study suggest that the pattern and parameters associated with inhalant use among those presenting to a tertiary care drug dependence center tend to remain stable.

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

Collapse of florisitic diversity coincident with a fungal spike and iridium anomaly at the Cretaceous-Tertiary boundary in New Zealand  

NASA Astrophysics Data System (ADS)

Analysis of pollen and spore assemblages from both terrestrial and near-shore marine sediments in New Zealand had revealed an instant, extensive destruction of land plants directly associated with the Cretaceous-Tertiary boundary (KTB) event, (Vajda et al., 2001). A recent palynological investigation, based on millimeter resolution sampling of the terrestrial KTB sediments at Moody Creek Mine, Greymouth coalfield, New Zealand has been carried out. The sediments were deposited in a terrestrial wetland environment and the KTB is defined within a coal seam. Preliminary results of the high-resolution investigation reveal a diverse vascular plant spore/pollen flora (>80 species) that was replaced by an assemblage impoverished in vascular plant pollen and spores, but rich in fungal spores. The "barren" layer is coincident with the extinction of several miospore taxa and contains an iridium abundance of 3ppb. The fungal spike covers 5 mm, and is followed by a 40-cm interval with abundant fern spores. The relative abundance of fern spores, increases from 25% below the boundary to 98% in the sediment following the KTB. We argue that the abrupt palynofloristic changes at this high southern palaeolatitude site are evidence of massive disruptions to terrestrial plant communities as a consequence of the Chicxulub impact. Palynofloristic evidence indicates that the complex mire and forest vegetation was totally devastated at the time of impact. Global cooling and several months with extremely low light levels following the impact, perhaps in combination with extensive wildfires would explain the devastation of the vegetation. The "barren" layer at the KTB corresponds to immediate post-impact conditions with low light levels and dust-related cooling unfavorable to forest growth but favoring saprophytic fungi. The recovery succession is initiated by opportunistic species of ground ferns, the plants best adapted to low light, lowered temperatures and high acidity. Vajda, V., Raine, I. &Hollis, C. (2001).

An exploration of gender differences in tertiary mathematics  

NASA Astrophysics Data System (ADS)

Data from 400 students in a tertiary mathematics course were analysed to explore gender differences on a number of variables associated with learning mathematics. It was concluded that while differences did occur on variables associated with confidence, self-concept, test anxiety and quantitative ability indicating a detrimental effect for women, compensating behaviour by women, including increased assignment work and tutorial attendance, resulted in comparable final course performance for women and men. These findings are discussed in light of participation rates of women in mathematics.

Tertiary cytoreduction in the setting of recurrent ovarian cancer (Review)  

PubMed Central

Ovarian cancer is the most lethal gynecological malignancy, with aggressive surgical debulking and adjuvant chemotherapy as the main treatment modalities. Optimal debulking during the primary surgery is significantly correlated with prolonged survival. As surgical techniques and chemotherapeutic agents improve, more patients with prolonged survival may face secondary and tertiary recurrences. The role of surgical debulking in secondary cytoreduction (SC) is not clearly defined and is based on retrospective series. The treatment of patients with primary or secondary recurrences generally consists of second-line chemotherapy, but may be performed on medically fit patients in certain circumstances. A limited number of studies concerning tertiary cytoreduction (TC) in cases of secondary recurrences have been published. In these studies, conventional prognostic factors for SC, including ascites, an advanced International Federation of Gynecology and Obstetrics (FIGO) stage and/or peritoneal carcinomatosis, did not apply to TC, but the post-operative residual tumor load was significant in determining the prognosis. A limited number of patients with completely-resectable tumors may have an opportunity for a maximal cytoreduction in these circumstances. TC appears to result in a favorable outcome and moderate complication rates. The surgery is an available option for patients with recurrence, in whom a complete tumor resection may be achieved.

Tertiary Intratumor Lymphoid Tissue in Colo-Rectal Cancer  

PubMed Central

Ectopic (or tertiary) lymphoid tissue develops at sites of inflammation or infection in non lymphoid organs and is associated with chronic inflammation. In colon mucosa, small lymphoid aggregates are already present in homeostatic conditions, as part of the gut-associated lymphoid tissue and play an essential role in the immune response to perturbations of the mucosal microenvironment. Despite the recognized role of inflammation in tumor progression, the presence and biological function of lymphoid tissue in cancer has been poorly investigated. We identified aggregates of lymphocytes resembling tertiary lymphoid tissue in human colorectal cancer specimens; intratumor accumulations of lymphocytes display a high degree of compartmentalization, with B and T cells, mature dendritic cells and a network of CD21+ follicular dendritic cells (FDC). We analyzed the adaptation of colon lymphoid tissue in a murine model of colitis-associated cancer (AOM/DSS). B cell follicle formation increases in the context of the chronic inflammation associated to intestinal neoplasia, in this model. A network of lymphatic and haematic vessels surrounding B cell follicles is present and includes high endothelial venules (HEV). Future task is to determine whether lymphoid tissue contributes to the persistence of the tumor-associated inflammatory reaction, rather than represent a functional immune compartment, potentially participating to the anti tumor response.

Chronological trends of emission, environmental level and human exposure of POPs over the last 10 years (1999-2010) in Korea: implication to science and policy.  

PubMed

Despite the first comprehensive reviewing on POPs status in Korea, a previous review chapter (Departments in Environmental Science, Volume 7, Chapter 2) could not discuss and evaluate the temporal trends and the effect of the efforts and policies invested in POPs control and management, since most data were based on individual research results of academic groups in which POPs could not be systematically monitored in terms of time and space. Recently, we have collected monitoring data long enough in time (over 10 years) and wide enough in space (covering various land-use patterns and the Korean peninsula), which were produced at national monitoring stations under the governmental programs. This study aimed to elucidate the temporal trends of POPs emissions, concentrations in multiple compartments (air, water, soil, sediment, organisms, and marine products), and human exposure. The chronological data available for all the subjects investigated were present only for PCDDs/DFs and coPCBs. Their emission reduction with half-lives of ~2 years was followed by contemporaneous decrease of contamination levels in inland compartments, while a considerably slow or slight reduction occurred in human exposure and its related compartments (fishes and shellfishes as foodstuffs consumed, and marine compartments). The findings prove that a lag-time is present for the efforts of emission reduction to be so much effective as to be reflected directly in human exposure, and such a lag-time can be related with the fates connecting inland and marine environments. PCBs showed faster reduction in human exposure than dioxin-like compounds. As for other POPs, chronological trends and half-lives could not be determined owing to low detection frequencies of PCBs and OCPs in environmental compartments, the absence of monitoring data for OCPs in human exposure, and data limitation for emerging POPs present in recent a few years. Monitoring strategies are also recommended based on this meta-analysis. PMID:23993838

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

The genotype dependent presence of pyrrolizidine alkaloids as tertiary amine in Jacobaea vulgaris.  

PubMed

Secondary metabolites such as pyrrolizidine alkaloids (PAs) play a crucial part in plant defense. PAs can occur in plants in two forms: tertiary amine (free base) and N-oxide. PA extraction and detection are of great importance for the understanding of the role of PAs as plant defense compounds, as the tertiary PA form is known for its stronger influence on several generalist insects, whereas the N-oxide form is claimed to be less deterrent. We measured PA N-oxides and their reduced tertiary amines by liquid chromatography-tandem mass spectrometry (LC-MS/MS). We show that the occurrence of tertiary PAs is not an artifact of the extraction and detection method. We found up to 50% of tertiary PAs in shoots of Jacobine - chemotype plants of Jacobaea vulgaris. Jacobine and its derivatives (jacoline, jaconine, jacozine and dehydrojaconine) may occur for more than 20% in reduced form in the shoots and more than 10% in the roots. For 22 PAs detected in F(2) hybrids (J. vulgaris × Jacobaea aquatica), we calculate the tertiary amine percentage (TA%=the tertiary amine concentration/(tertiary amine concentration+the corresponding N-oxide concentration) × 100). We found that the TA% for various PAs was genotype-dependent. Furthermore, TA% for the different PAs were correlated and the highest correlations occurred between PAs which share high structural similarity. PMID:21159354

Tracing groundwater with low-level detections of halogenated VOCs in a fractured carbonate-rock aquifer, Leetown Science Center, West Virginia, USA  

USGS Publications Warehouse

Measurements of low-level concentrations of halogenated volatile organic compounds (VOCs) and estimates of groundwater age interpreted from 3H/3He and SF6 data have led to an improved understanding of groundwater flow, water sources, and transit times in a karstic, fractured, carbonate-rock aquifer at the Leetown Science Center (LSC), West Virginia. The sum of the concentrations of a set of 16 predominant halogenated VOCs (TDVOC) determined by gas chromatography with electron-capture detector (GC–ECD) exceeded that possible for air–water equilibrium in 34 of the 47 samples (median TDVOC of 24,800 pg kg?1), indicating that nearly all the water sampled in the vicinity of the LSC has been affected by addition of halogenated VOCs from non-atmospheric source(s). Leakage from a landfill that was closed and sealed nearly 20 a prior to sampling was recognized and traced to areas east of the LSC using low-level detection of tetrachloroethene (PCE), methyl chloride (MeCl), methyl chloroform (MC), dichlorodifluoromethane (CFC-12), and cis-1,2-dichloroethene (cis-1,2-DCE). Chloroform (CHLF) was the predominant VOC in water from domestic wells surrounding the LSC, and was elevated in groundwater in and near the Fish Health Laboratory at the LSC, where a leak of chlorinated water occurred prior to 2006. The low-level concentrations of halogenated VOCs did not exceed human or aquatic-life health criteria, and were useful in providing an awareness of the intrinsic susceptibility of the fractured karstic groundwater system at the LSC to non-atmospheric anthropogenic inputs. The 3H/3He groundwater ages of spring discharge from the carbonate rocks showed transient behavior, with ages averaging about 2 a in 2004 following a wet climatic period (2003–2004), and ages in the range of 4–7 a in periods of more average precipitation (2008–2009). The SF6 and CFC-12 data indicate older water (model ages of 10s of years or more) in the low-permeability shale of the Martinsburg Formation located to the west of the LSC. A two-a record of specific conductance, water temperature, and discharge recorded at 30-min intervals demonstrated an approximately 3-month lag in discharge at Gray Spring. The low groundwater ages of waters from the carbonate rocks support rapid advective transport of contaminants from the LSC vicinity, yet the nearly ubiquitous occurrence of low-level concentrations of halogenated VOCs at the LSC suggests the presence of long-term persistent sources, such as seepage from the closed and sealed landfill, infiltration of VOCs that may persist locally in the epikarst, exchange with low-permeability zones in fractured rock, and upward leakage of older water that may contain elevated concentrations of halogenated VOCs from earlier land use activities.

Pattern of traumatic brain injury treated by general surgeons in a tertiary referral hospital.  

PubMed

The number of polytrauma patient with associated brain injury or commonly referred as 'head injury' has increased tremendously in recent times courtesy to road traffic accident or other causes. This prospective observational study was conducted in patients of head injury admitted through emergency in the department of general surgery in NRS Medical College, Kolkata during the year 2011 to determine the pattern of head injury patients admitted and nature of intervention. A total number of 3861 patients were admitted in a single year. Obviously this represents the tip of the iceburg. Traumatic brain injury was the highest in the age group of 31-40 years (33.5%) followed by 21-30 years (29.1%) in the most fruitful phase of life. The traumatic brain injury death was more common in males. The maximum number of cases was from rural areas ie, farmers and labours. To minimise the morbidity and mortality resulting from head injury there is need for better maintenance of roads, improvement of road visibility and lighting, rigid enforcement of traffic rules and imparting road safety education to school children. Despite valiant efforts and advancement in medical sciences and infrastructure in the form of neurosurgery departments and trauma care units to cope with the changing world of trauma, there still remains a huge responsibility and a definite part to be played by the general surgeons to manage head injury patient even in tertiary hospitals.

Tertiary care availability and adolescent pregnancy characteristics in Saudi Arabia  

PubMed Central

Background In this study, we aimed to assess the rate of adolescent delivery in a Saudi tertiary health care center and to investigate the association between maternal age and fetal, neonatal, and maternal complications where a professional tertiary medical care service is provided. Methods A cross-sectional study was performed between 2005 and 2010 at King Abdulaziz Medical City, Riyadh, Saudi Arabia. All primigravid Saudi women ?24 weeks gestation, carrying a singleton pregnancy, aged <35 years, and with no chronic medical problems were eligible. Women were divided into three groups based on their age, ie, group 1 (G1) <16 years, group 2 (G2) ?16 up to 19 years, and group 3 (G3) ?19 up to 35 years. Data were collected from maternal and neonatal medical records. We calculated the association between the different age groups and maternal characteristics, as well as events and complications during the antenatal period, labor, and delivery. Results The rates of adolescent delivery were 20.0 and 16.3 per 1,000 births in 2009 and 2010, respectively. Compared with G1 and G2 women, G3 women tended to have a higher body mass index, a longer first and second stage of labor, more blood loss at delivery, and a longer hospital stay. Compared with G1 and G2 women, respectively, G3 women had a 42% and a 67% increased risk of cesarean section, and had a 52% increased risk of instrumental delivery. G3 women were more likely to develop gestational diabetes or anemia, G2 women had a three-fold increased risk of premature delivery (odds ratio 2.81), and G3 neonates had a 50% increased overall risk of neonatal complications (odds ratio 0.51). Conclusion The adolescent birth rate appears to be low in central Saudi Arabia compared with other parts of the world. Excluding preterm delivery, adolescent delivery cared for in a tertiary health care center is not associated with a significantly increased medical risk to the mother, fetus, or neonate. The psychosocial effect of adolescent pregnancy and delivery needs to be assessed. PMID:24729733

Geotechnical simulation of tertiary creep behavior of landslides induced by extreme rainfall  

NASA Astrophysics Data System (ADS)

Rainstorm indirectly provokes landslides because of its ability to level up the groundwater table after certain hours dropping. This process causes excess pore water pressure generation and soil liquefaction at the sliding surface and determines the behavior of landslides triggered by extreme rainfall. Creep deformations are commonly observed in a slope before sliding down. Creep behavior, in particular tertiary creep behavior, is therefore the main focus in predicting the final failure time of a slope. Progressive failure/tertiary creep deformation is the stage when strain rate exponentially increases just before final collapse. This study aims at simulating geotechnical model of tertiary creep behavior in soils, which was empirically discovered by Saito (1965) and Fukuzono (1985) to help issue warning of rainfall-induced landslides in developing countries where there is no implemented methodology for issuing effective warming of landslides yet. Tertiary creep to failure is reproduced by pore-pressure-controlled test in ring shear apparatus, through which obvious relationship of A and ? (alpha) values was obtained, following consistent range with those found in previous studies under slightly deviated trend due to different test condition: pore-pressure-controlled and shear stress development tests. Constant shear speed test under shear speed of v=1cm/s was conducted in the ring shear apparatus to obtain the relation curve of shear resistance and shear displacement, from which exponential expression of creep behavior is originated. The model formula is governed by two constants: m and ? (gamma) whose relation with constants A and alpha was examined. Geotechnical simulation of creep behavior is then constructed by assuming that shear strength of soil increases and remains constant after reaching its maximum value in residual condition. This is to quantify normally consolidated condition of soils in natural slope. Shear resistance diminishes, while pore pressure is gradually generated through time until shear resistance is smaller than initial shear stress, and failure encounters. The large shear displacement took place after failure is used to calculate velocity and acceleration of virtual surface displacement. A and alpha values are measured through the plot of velocity and acceleration in log scale and compared with those of laboratory tests. In similar way, additional formulation of shear stress development condition to failure was also investigated. Consequently, model simulation of creep behavior to develop a most appropriate method for landslide early warning is successfully developed through very good correlation with experimental results. The constant m and ? are corresponded to A and ? respectively. A value gets smaller when m is higher, whereas alpha and gamma increase accordingly. The m value best fitted with experimental result is 0.1. Deviated trends were also observed in pore pressure control and shear stress increase simulations. The result shows that higher alpha value, higher landslide susceptibility is expected.
