    Introduction: Emergency treatment of patients with acute myocardial infarction is very important. Streptokinase in Iran is often as the only clot-busting medication is used. The purpose of using streptokinase medication is to revive the ischemic heart tissue, although has dangerous complications too. Therefore, the present study aimed to determine the effect of streptokinase on reperfusion after acute myocardial infarction and its complications, has been designed and conducted. Materials and Methods: This is an Ex-post facto study. The study population included patients who suffer from acute myocardial infarction. The sample size was 300 patients, and 2 groups were matched, in variables of age, sex, underlying disease, frequencies and area of MI. Data collection did by researcher making questionnaire, that accept face and content validity by 10 expert researcher, the reliability was conducted with Spearman’s test (r=0.85) by Test-retest method. Data analysis did by SPSS software: V 12. Findings: Mean of EF in SK group was (46.15±8.11) and in control group was (43.11±12.57). Significant relationship was seen between SK, arrhythmia occurring and improve EF reperfusion by chi-square test (p=0.028), (p=0.020). The most arrhythmia in SK group was Ventricular Tachycardia (20.7%). Significant statistical relation between SK and mortality were found by Chi-square test (p=0.001). But a meaningful statistical relation was not found between SK and pulmonary edema incidence (p=0.071). Conclusions: Nurses of CCU should be aware about SK complications such as hypotension, bleeding and arrhythmias. Proposed compare SK and tissue plasminogen drug in reperfusion and complications effect. PMID:25946921

    Most ex-post evaluations of research funding programs are based on bibliometric methods and, although this approach has been widely used, it only examines one facet of the project's impact, that is, scientific productivity. More comprehensive models of payback assessment of research activities are designed for large-scale projects with extensive funding. The purpose of this study was to design and implement a methodology for the ex-post evaluation of small-scale projects that would take into account both the fulfillment of projects' stated objectives as well as other wider benefits to society as payback measures. We used a two-phase ex-post approach to appraise impact for 173 small-scale projects funded in 2007 and 2008 by a Spanish network center for research in epidemiology and public health. In the internal phase we used a questionnaire to query the principal investigator (PI) on the outcomes as well as actual and potential impact of each project; in the external phase we sent a second questionnaire to external reviewers with the aim of assessing (by peer-review) the performance of each individual project. Overall, 43% of the projects were rated as having completed their objectives "totally", and 40% "considerably". The research activities funded were reported by PIs as socially beneficial their greatest impact being on research capacity (50% of payback to society) and on knowledge translation (above 11%). The method proposed showed a good discriminating ability that makes it possible to measure, reliably, the extent to which a project's objectives were met as well as the degree to which the project contributed to enhance the group's scientific performance and of its social payback.

    2015-11-15

    - Highlights: • We defend the usefulness of causal maps (CM) for ex-post impact assessment of dams. • Political decisions are presented as unavoidable technical measures. • CM enable the identification of multiple causes involved in the dam impacts. • An alternative management of the dams is shown from the precise tracking of the causes. • Participatory CM better the quality of information and the governance of the research. This paper presents the results of an ex-post assessment of two important dams in Brazil. The study follows the principles of Social Impact Management, which offer a suitable framework for analyzing the complex social transformations triggered by hydroelectric dams. In the implementation of this approach, participative causal maps were used to identify the ex-post social impacts of the Porto Primavera and Rosana dams on the community of Porto Rico, located along the High Paraná River. We found that in the operation of dams there are intermediate causes of a political nature, stemming from decisions based on values and interests not determined by neutral, exclusively technical reasons; and this insight opens up an area of action for managing the negative impacts of dams.

    2011-01-01

    Context: Understanding how and why programs work—not simply whether they work—is crucial. Good theory is indispensable to advancing the science of improvement. We argue for the usefulness of ex post theorization of programs. Methods: We propose an approach, located within the broad family of theory-oriented methods, for developing ex post theories of interventional programs. We use this approach to develop an ex post theory of the Michigan Intensive Care Unit (ICU) project, which attracted international attention by successfully reducing rates of central venous catheter bloodstream infections (CVC-BSIs). The procedure used to develop the ex post theory was (1) identify program leaders’ initial theory of change and learning from running the program; (2) enhance this with new information in the form of theoretical contributions from social scientists; (3) synthesize prior and new information to produce an updated theory. Findings: The Michigan project achieved its effects by (1) generating isomorphic pressures for ICUs to join the program and conform to its requirements; (2) creating a densely networked community with strong horizontal links that exerted normative pressures on members; (3) reframing CVC-BSIs as a social problem and addressing it through a professional movement combining “grassroots” features with a vertically integrating program structure; (4) using several interventions that functioned in different ways to shape a culture of commitment to doing better in practice; (5) harnessing data on infection rates as a disciplinary force; and (6) using “hard edges.” Conclusions: Updating program theory in the light of experience from program implementation is essential to improving programs’ generalizability and transferability, although it is not a substitute for concurrent evaluative fieldwork. Future iterations of programs based on the Michigan project, and improvement science more generally, may benefit from the updated theory present here

  9. Financing long-term care: ex ante, ex post or both?

    2015-03-01

    This paper attempts to examine the heterogeneity in the public financing of long-term care (LTC) and the wide-ranging instruments in place to finance LTC services. We distinguish and classify the institutional responses to the need for LTC financing as ex ante (occurring prior to when the need arises, such as insurance) and ex post (occurring after the need arises, such as public sector and family financing). Then, we examine country-specific data to ascertain whether the two types of financing are complements or substitutes. Finally, we examine exploratory cross-national data on public expenditure determinants, specifically economic, demographic and social determinants. We show that although both ex ante and ex post mechanisms exist in all countries with advanced industrial economies and despite the fact that instruments are different across countries, ex ante and ex post instruments are largely substitutes for each other. Expenditure estimates to date indicate that the public financing of LTC is highly sensitive to a country's income, ageing of the population and the availability of informal caregiving.

    Ex post manipulation of ∼1.1 μm emitting InGaAs/GaAs-based quantum dot–quantum well tunnel injection light emitting devices is demonstrated experimentally. The devices were operated at elevated forward currents until irreversible alterations were observed. As a result, changes in the steady-state optical spectra (electroluminescence, photoluminescence, and photocurrent), in carrier kinetics, in transport properties, and real structure are found. Except for degradation effects, e.g., of larger quantum dots, also restoration/annealing effects such as increased tunnel barriers are observed. The results furnish evidence for a generic degradation mode of nanostructures. We qualitatively interpret the mechanisms involved on both the nanoscopic and the device scales.

    On October 9, 1996, Bruce Babbitt, then-Secretary of the U.S. Department of the Interior signed the Record of Decision (ROD) on operating criteria for the Glen Canyon Dam (GCD). Criteria selected were based on the Modified Low Fluctuating Flow (MLFF) Alternative as described in the Operation of Glen Canyon Dam, Colorado River Storage Project, Arizona, Final Environmental Impact Statement (EIS) (Reclamation 1995). These restrictions reduced the operating flexibility of the hydroelectric power plant and therefore its economic value. The EIS provided impact information to support the ROD, including an analysis of operating criteria alternatives on power system economics. This ex post study reevaluates ROD power economic impacts and compares these results to the economic analysis performed prior (ex ante) to the ROD for the MLFF Alternative. On the basis of the methodology used in the ex ante analysis, anticipated annual economic impacts of the ROD were estimated to range from approximately $15.1 million to $44.2 million in terms of 1991 dollars ($1991). This ex post analysis incorporates historical events that took place between 1997 and 2005, including the evolution of power markets in the Western Electricity Coordinating Council as reflected in market prices for capacity and energy. Prompted by ROD operational restrictions, this analysis also incorporates a decision made by the Western Area Power Administration to modify commitments that it made to its customers. Simulated operations of GCD were based on the premise that hourly production patterns would maximize the economic value of the hydropower resource. On the basis of this assumption, it was estimated that economic impacts were on average $26.3 million in $1991, or $39 million in $2009.

    2014-02-01

    This paper proposes and discusses two different approaches to the definition of inequality in health: the ex-ante and the ex-post approach. It proposes strategies for measuring inequality of opportunity in health based on the path-independent Atkinson equality index. The proposed methodology is illustrated using data from the British Household Panel Survey; the results suggest that in the period 2000-2005, at least one-third of the observed health equalities in the UK were equalities of opportunity.

    The ANN method has been applied by means of multilayered feedforward neural networks (MLFNs) by using different macroeconomic variables such as the exchange rate of USD/TRY, gold prices, and the Borsa Istanbul (BIST) 100 index based on monthly data over the period of January 2000 and September 2014 for Turkey. Vector autoregressive (VAR) method has also been applied with the same variables for the same period of time. In this study, different from other studies conducted up to the present, ENCOG machine learning framework has been used along with JAVA programming language in order to constitute the ANN. The training of network has been done by resilient propagation method. The ex post and ex ante estimates obtained by the ANN method have been compared with the results obtained by the econometric forecasting method of VAR. Strikingly, our findings based on the ANN method reveal that there is a possibility of financial distress or a financial crisis in Turkey starting from October 2017. The results which were obtained with the method of VAR also support the results of ANN method. Additionally, our results indicate that the ANN approach has more superior prediction performance than the VAR method.

  1. Willingness to pay for rapid diagnostic tests for the diagnosis and treatment of malaria in southeast Nigeria: ex post and ex ante

    PubMed Central

    2010-01-01

    Background The introduction of rapid diagnostic tests (RDTs) has improved the diagnosis and treatment of malaria. However, any successful control of malaria will depend on socio-economic factors that influence its management in the community. Willingness to pay (WTP) is important because consumer responses to prices will influence utilization of services and revenues collected. Also the consumer's attitude can influence monetary valuation with respect to different conditions ex post and ex ante. Methods WTP for RDT for Malaria was assessed by the contingent valuation method using a bidding game approach in rural and urban communities in southeast Nigeria. The ex post WTP was assessed at the health centers on 618 patients immediately following diagnosis of malaria with RDT and the ex ante WTP was assessed by household interviews on 1020 householders with a prior history of malaria. Results For the ex ante WTP, 51% of the respondents in urban and 24.7% in rural areas were willing to pay for RDT. The mean WTP (235.49 naira) in urban is higher than WTP (182.05 Naira) in rural areas. For the ex post WTP, 89 and 90.7% of the respondents in urban and rural areas respectively were WTP. The mean WTP (372.30 naira) in urban is also higher than (296.28 naira) in rural areas. For the ex post scenario, the lower two Social Economic Status (SES) quartiles were more willing to pay and the mean WTP is higher than the higher two SES while in the ex ante scenario, the higher two SES quartiles were more WTP and with a higher WTP than the lower two SES quartile. Ex ante and ex post WTP were directly dependent on costs. Conclusion The ex post WTP is higher than the ex ante WTP and both are greater than the current cost of RDTs. Urban dwellers were more willing to pay than the rural dwellers. The mean WTP should be considered when designing suitable financial strategies for making RDTs available to communities.

    The vignette we use as the introduction works to define and distinguish the concepts of de jure and de facto pedagogical actions, especially as related to Latin@ education and its relationship with STEM fields. The authors assert that de jure educational policies, which are often legal guidelines that mandate minimum levels of compliance, unfortunately become translated to mean the normative way to implement educational practice. Hence, going above and beyond the call of duty to educate Latin@ children and youth through culturally meaningful STEM practices while respecting, affirming, and utilizing decolonizing ways of viewing science and math is not viewed as standard. Thus, it is imperative that STEM educators who work with Latin@ learners demand that de jure education guidelines translated as de facto pedagogical actions are not enough. On the contrary, de jure and de facto ways of teaching and learning should always consist of a counterhegemonic normative.

  16. Implications of Transitioning from De Facto to Engineered Water Reuse for Power Plant Cooling.

    PubMed

    Barker, Zachary A; Stillwell, Ashlynn S

    2016-05-17

    Thermoelectric power plants demand large quantities of cooling water, and can use alternative sources like treated wastewater (reclaimed water); however, such alternatives generate many uncertainties. De facto water reuse, or the incidental presence of wastewater effluent in a water source, is common at power plants, representing baseline conditions. In many cases, power plants would retrofit open-loop systems to cooling towers to use reclaimed water. To evaluate the feasibility of reclaimed water use, we compared hydrologic and economic conditions at power plants under three scenarios: quantified de facto reuse, de facto reuse with cooling tower retrofits, and modeled engineered reuse conditions. We created a genetic algorithm to estimate costs and model optimal conditions. To assess power plant performance, we evaluated reliability metrics for thermal variances and generation capacity loss as a function of water temperature. Applying our analysis to the greater Chicago area, we observed high de facto reuse for some power plants and substantial costs for retrofitting to use reclaimed water. Conversely, the gains in reliability and performance through engineered reuse with cooling towers outweighed the energy investment in reclaimed water pumping. Our analysis yields quantitative results of reclaimed water feasibility and can inform sustainable management of water and energy.

    Fourteen surveys were conducted at Farallon De Medinilla (a U.S. Department of Defense bombing range in the Mariana Archipelago) between 1997 and 2012; annual surveys were conducted from 1999 through 2012. There was no evidence that the condition of the biological resources assessed had changed, or been adversely impacted to a significant degree by the training activities being conducted there. Restricted access has resulted in a de-facto preserve effect and outweighs minor negative impacts from training. The health, abundance and biomass of fishes, corals and other marine resources are comparable to or superior to those in similar habitats at other locations within the Mariana Archipelago. Our research suggests that the greatest threat to FDM's marine resources is from fishermen, not military training activities.

    De facto potable reuse occurs when treated wastewater is discharged into surface waters upstream of potable drinking water treatment plant (DWTP) intakes. Wastewater treatment plant (WWTP) discharges may pose water quality risks at the downstream DWTP, but additional flow aids in providing a reliable water supply source. In this work de facto reuse is analyzed for 2056 surface water intakes serving 1210 DWTPs across the U.S.A. that serve greater than 10,000 people, covering approximately 82% of the nation’s population. An ArcGIS model is developed to assess spatial relationships between DWTPs and WWTPs, with a python script designed to perform a network analysis by hydrologic region. A high frequency of de facto reuse occurrence was observed; 50% of the DWTP intakes are potentially impacted by upstream WWTP discharges. However, the magnitude of de facto reuse was seen to be relatively low, where 50% of the impacted intakes contained less than 1% treated municipal wastewater under average streamflow conditions. De facto reuse increased greatly under low streamflow conditions (modeled by Q95), with 32 of the 80 sites yielding at least 50% treated wastewater, this portion of the analysis is limited to sites where stream gauge data was readily available.

  1. Spatial Heterogeneity in Fishing Creates de facto Refugia for Endangered Celtic Sea Elasmobranchs

    The life history characteristics of some elasmobranchs make them particularly vulnerable to fishing mortality; about a third of all species are listed by the IUCN as Threatened or Near Threatened. Marine Protected Areas (MPAs) have been suggested as a tool for conservation of elasmobranchs, but they are likely to be effective only if such populations respond to fishing impacts at spatial-scales corresponding to MPA size. Using the example of the Celtic Sea, we modelled elasmobranch biomass (kg h−1) in fisheries-independent survey hauls as a function of environmental variables and ‘local’ (within 20 km radius) fishing effort (h y−1) recorded from Vessel Monitoring Systems data. Model selection using AIC suggested strongest support for linear mixed effects models in which the variables (i) fishing effort, (ii) geographic location and (iii) demersal fish assemblage had approximately equal importance in explaining elasmobranch biomass. In the eastern Celtic Sea, sampling sites that occurred in the lowest 10% of the observed fishing effort range recorded 10 species of elasmobranch including the critically endangered Dipturus spp. The most intensely fished 10% of sites had only three elasmobranch species, with two IUCN listed as Least Concern. Our results suggest that stable spatial heterogeneity in fishing effort creates de facto refugia for elasmobranchs in the Celtic Sea. However, changes in the present fisheries management regime could impair the refuge effect by changing fisher's behaviour and displacing effort into these areas. PMID:23166635

  3. The Educational Function of an Astronomy Research Experience for Undergraduates Program as Described by Female Participants

    NASA Astrophysics Data System (ADS)

    Slater, Stephanie

    2010-01-01

    The long-running REU-program is tacitly intended to increase retention and provide "an important educational experience" for undergraduates, particularly women, minorities and underrepresented groups. This longitudinal, two-stage study was designed to explore the ways in which the REU acted as an educational experience for 51 women in the field of astronomy. Stage-1 consisted of an ex post facto analysis of data collected over 8 years, including multiple interviews with each participant during their REU, annual open-ended alumni surveys, faculty interviews, and extensive field notes. Four themes emerged, related to developing understandings of the nature of professional scientific work, the scientific process, the culture of academia, and an understanding of the "self." Analysis provided an initial theory that was used to design the Stage-2 interview protocol. In Stage-2, over 10 hours of interviews were conducted with 8 participants selected for their potential to disconfirm the initial theory. Results indicate that the REU provided a limited impact in terms of participants’ knowledge of professional astronomy as a largely computer-based endeavor. The REU did not provide a substantive educational experience related to the nature of scientific work, the scientific process, the culture of academia, participants' conceptions about themselves as situated in science, or other aspects of the "self,” were limited. Instead, the data suggests that these women began the REU with pre-existing and remarkably strong conceptions in these areas, and that the REU did not functional to alter those states. These conceptions were frequently associated with other mentors/scientist interactions, from middle school into the undergraduate years. Instructors and family members also served as crucial forces in shaping highly developed, stable science identities. Sustained relationships with mentors were particularly transformational. These findings motivate an ongoing research agenda

Data collected were subjected to descriptive and inferential statistics. The result revealed that a total of 644 articles were indexed and abstracted, 35% of these was done in 2010. Results for awareness show 452 (60.11%) to be aware in 2008. A total 584 articles were indexed and abstracted from which 167 (28.59%) was retrieved in 2006. Patrons, 270 (35.90%) attributed the poor use of the service to assumption it is a referral unit. The hypothesis testing revealed that there is significant association between articles indexed and abstracted with information consulted by patrons (?2cal,100.31>?2tab,9.488) at 5% level of probability and df, 4. In conclusion, enormous documents on Nigerian agriculture are indexed and abstracted in the unit, implying that the service is desirous and consistent.

  19. Ex-post assessment of genetically modified, low level presence in Canadian flax.

    PubMed

    Booker, Helen M; Lamb, Eric G; Smyth, Stuart J

    2017-03-17

    Canada is the world's largest producer and exporter of flaxseed. In 2009, DNA from deregistered genetically modified (GM) CDC Triffid was detected in a shipment of Canadian flaxseed exported to Europe, causing a large decrease in the amount of flax planted in Canada and a major shift in export markets. The flax industry in Canada undertook major changes to ensure the removal of transgenic flax from the supply chain. To demonstrate compliance, Canada adopted a protocol involving testing grain samples (post-harvest) using an RT-PCR test for the construct found in CDC Triffid. Efforts to remove the presence of GM flax from the value chain included reconstituting major flax varieties from GM-free plants. The reconstituted varieties represented the majority of planting seed in 2014. This study re-evaluates GM flax presence in Canadian grain stocks for an updated dataset (2009-2015) using a previously described simulation model to estimate low-level GM presence. Additionally, losses to the Canadian economy resulting from the reduction in flax production and export opportunities, costs associated with reconstituting major flax varieties, and testing for the presence of GM flax along the flax value chain are estimated.

    2012-03-01

    Compared to the undergraduate population, the number of students obtaining physics degrees has been declining since the 1960s. This trend continues despite the increasing number of students taking introductory physics courses in high school and college. Our work uses an ex-post facto design to study the factors that influence students' decision to pursue a career in physics at the beginning of college. These factors include high school physics classroom experiences, other science-related experiences, and students' career motivations. The data used in this study is drawn from the Persistence Research in Science and Engineering (PRiSE) Project, a large-scale study that surveyed a nationally representative sample of college/university students enrolled in introductory English courses about their interests and prior experiences in science.

  12. A call for change: clinical evaluation of student registered nurse anesthetists.

    The ability to integrate theory with practice is integral to a student's success. A common reason for attrition from a nurse anesthesia program is clinical issues. To document clinical competence, students are evaluated using various tools. For use of a clinical evaluation tool as possible evidence for a student's dismissal, an important psychometric property to ensure is instrument validity. Clinical evaluation instruments of nurse anesthesia programs are not standardized among programs, which suggests a lack of instrument validity. The lack of established validity of the instruments used to evaluate students' clinical progress brings into question their ability to detect a student who is truly in jeopardy of attrition. Given this possibility, clinical instrument validity warrants research to be fair to students and improve attrition rates based on valid data. This ex post facto study evaluated a 17-item clinical instrument tool to demonstrate the need for validity of clinical evaluation tools. It also compared clinical scores with scores on the National Certification Examination.

    2016-01-01

    The present paper examines the relation between size, accumulation and performance for research grants, where we examine the relation between grant size for Centres of Excellence (CoE) funded by the Danish National Research Foundation (DNRF) and various ex post research performance measures, including impact and shares of highly cited articles. We examine both the relation between size and performance and also how performance for CoEs evolves over the course of grant periods. In terms of dynamics, it appears that performance over the grant period (i.e. 10 years) is falling for the largest CoEs, while it is increasing for those among the smallest half. Overall, multivariate econometric analysis finds evidence that performance is increasing in grant size and over time. In both cases, the relation appears to be non-linear, suggesting that there is a point at which performance peaks. The CoEs have also been very successful in securing additional funding, which can be viewed as a ‘cumulative effect’ of center grants. In terms of new personnel, the far majority of additional funding is spent on early career researchers, hence, this accumulation would appear to have a ‘generational’ dimension, allowing for scientific expertise to be passed on to an increasing number of younger researchers.

    Most Transdisciplinary Research (TdR) projects combine scientific research with the building of decision making capacity for the involved stakeholders. These projects usually deal with complex, societally relevant, real-world problems. This paper focuses on TdR projects, which integrate the knowledge of researchers and stakeholders in a collaborative transdisciplinary process through structured methods of mutual learning. Previous research on the evaluation of TdR has insufficiently explored the intended effects of transdisciplinary processes on the real world (societal effects). We developed an evaluation framework for assessing the societal effects of transdisciplinary processes. Outputs (measured as procedural and product-related involvement of the stakeholders), impacts (intermediate effects connecting outputs and outcomes) and outcomes (enhanced decision making capacity) are distinguished as three types of societal effects. Our model links outputs and outcomes of transdisciplinary processes via the impacts using a mediating variables approach. We applied this model in an ex post evaluation of a transdisciplinary process. 84 out of 188 agents participated in a survey. The results show significant mediation effects of the two impacts "network building" and "transformation knowledge". These results indicate an influence of a transdisciplinary process on the decision making capacity of stakeholders, especially through social network building and the generation of knowledge relevant for action.

    Restructuring of utilities raises questions about the future of conservation programs. One of the greatest obstacles has been the persistent uncertainity among utility planners regarding true resource effectiveness and cost-effectiveness of conservation relative to conventional generation. The authors use econometric techniques to examine the aggregate commercial and industrial conservation impacts reported. The paper shows that utility conservation programs have been effective in reducing electric loads and that utilities have reported accurately. 44 refs., 3 tabs.

    2010-12-01

    Recent analyses of the long-term societal benefits from early intervention (prenatal care, home visitation, and high quality preschool) for at-risk children commonly include significant savings to society in the form of reduced juvenile delinquency and adult criminal behavior. However, a nontrivial proportion of the reported benefits of several early intervention programs are based on forecasts of criminal behavior throughout adulthood conditional on intervention effects on delinquency in adolescence. Data from the Chicago Longitudinal Study (CLS), an investigation of the life course of 1,539 children from low-income families born in 1979-1980, are used to investigate the bias resulting from predicting the effect of early intervention on adult criminal behavior from the effect on delinquency in adolescence. The investigation concludes that the general method used to predict adult criminal behavior results in a conservative estimate of the reduction in the cost of adult criminal behavior attributed to early intervention.

    The literature indicates that elderly population is at high risk that affects their sexual activity; however, this is not the end of sexuality expression in this population. Elderly (people 65 years and older) who are healthy and active has more opportunities of sexual expression and activity in all forms, (including masturbation, and oral sex), and these activities can continue until 74 years or older. This study tries to explore if the Scale of Attitudes towards Sexuality Behavior in the Elderly develop in Puerto Rico, is a valid and reliable instrument to measure attitudes towards the sexuality in an elderly sample. In addition, the research tries to contribute to the progress and development of instruments that measure, and screen, sexuality aspects and risk behaviors that focus in the elderly population. This may help to promote future studies and the development of preventive programs that help to fulfill specific necessities in elderly. The research subjects consist of a secondary database sample of 265 adults of 65 years or older. The design of this study was an ex post facto type. The collected data were analyzed using descriptive statistics and factorial analyses to establish an association between the study variables (i.e., attitudes towards the sexuality and sexuality) using SPSS-X program version 14; also was concluded that the instrument is a valid and reliable (Alpha Cronbach = 0.95), which is considered adequate. It's expected that the scale will be valuable for future research in this area.

  3. The use of astronomy questions as an instrument to detect student's misconceptions regarding physics concepts at high school level by using CRI (Certainty of Response Index) as identification methods

    The aim of this research is to detect misconceptions in the concept of physics at high school level by using astronomy questions as a testing instrument. Misconception is defined as a thought or an idea that is different from what has been agreed by experts who are reliable in the field, and it is believed to interfere with the acquisition of new understanding and integration of new knowledge or skills. While lack of concept or knowledge can be corrected with the next instruction and learning, students who have misconceptions have to “unlearn” their misconception before learning a correct one. Therefore, the ability to differentiate between these two things becomes crucial. CRI is one of the methods that can identify efficiently, between misconceptions and lack of knowledge that occur in the students. This research used quantitative- descriptive method with ex-post-facto research approach. An instrument used for the test is astronomy questions that require an understanding of physics concepts to solve the problem. By using astronomy questions, it is expected to raise a better understanding such that a concept can be viewed from various fields of science. Based on test results, misconceptions are found on several topics of physics. This test also revealed that student's ability to analyse a problem is still quite low.

  4. A meta-composite software development approach for translational research.

    2013-06-01

    Translational researchers conduct research in a highly data-intensive and continuously changing environment and need to use multiple, disparate tools to achieve their goals. These researchers would greatly benefit from meta-composite software development or the ability to continuously compose and recompose tools together in response to their ever-changing needs. However, the available tools are largely disconnected, and current software approaches are inefficient and ineffective in their support for meta-composite software development. Building on the composite services development approach, the de facto standard for developing integrated software systems, we propose a concept-map and agent-based meta-composite software development approach. A crucial step in composite services development is the modeling of users' needs as processes, which can then be specified in an executable format for system composition. We have two key innovations. First, our approach allows researchers (who understand their needs best) instead of technicians to take a leadership role in the development of process models, reducing inefficiencies and errors. A second innovation is that our approach also allows for modeling of complex user interactions as part of the process, overcoming the technical limitations of current tools. We demonstrate the feasibility of our approach using a real-world translational research use case. We also present results of usability studies evaluating our approach for future refinements.

    Medical dosimetry education occupies a specialized branch of allied health higher education. Noted international shortages of health care workers, reduced university funding, limitations on faculty staffing, trends in learner attrition, and increased enrollment of nontraditional students force medical dosimetry educational leadership to reevaluate current admission practices. Program officials wish to select medical dosimetry students with the best chances of successful graduation. The purpose of the quantitative ex post facto correlation study was to investigate the relationship between applicant characteristics (cumulative undergraduate grade point average (GPA), science grade point average (SGPA), prior experience as a radiation therapist, and previous academic degrees) and the successful completion of a medical dosimetry program, as measured by graduation. A key finding from the quantitative study was the statistically significant positive correlation between a student׳s previous degree and his or her successful graduation from the medical dosimetry program. Future research investigations could include a larger research sample, representative of more medical dosimetry student populations, and additional studies concerning the relationship of previous work as a radiation therapist and the effect on success as a medical dosimetry student. Based on the quantitative correlation analysis, medical dosimetry leadership on admissions committees could revise student selection rubrics to place less emphasis on an applicant׳s undergraduate cumulative GPA and increase the weight assigned to previous degrees.

  6. Assessing cultural validity in standardized tests in stem education

    NASA Astrophysics Data System (ADS)

    Gassant, Lunes

    This quantitative ex post facto study examined how race and gender, as elements of culture, influence the development of common misconceptions among STEM students. Primary data came from a standardized test: the Digital Logic Concept Inventory (DLCI) developed by Drs. Geoffrey L. Herman, Michael C. Louis, and Craig Zilles from the University of Illinois at Urbana-Champaign. The sample consisted of a cohort of 82 STEM students recruited from three universities in Northern Louisiana. Microsoft Excel and the Statistical Package for the Social Sciences (SPSS) were used for data computation. Two key concepts, several sub concepts, and 19 misconceptions were tested through 11 items in the DLCI. Statistical analyses based on both the Classical Test Theory (Spearman, 1904) and the Item Response Theory (Lord, 1952) yielded similar results: some misconceptions in the DLCI can reliably be predicted by the Race or the Gender of the test taker. The research is significant because it has shown that some misconceptions in a STEM discipline attracted students with similar ethnic backgrounds differently; thus, leading to the existence of some cultural bias in the standardized test. Therefore the study encourages further research in cultural validity in standardized tests. With culturally valid tests, it will be possible to increase the effectiveness of targeted teaching and learning strategies for STEM students from diverse ethnic backgrounds. To some extent, this dissertation has contributed to understanding, better, the gap between high enrollment rates and low graduation rates among African American students and also among other minority students in STEM disciplines.

    1989-01-01

    This research used two key concepts from Roy's adaptation model of nursing to examine the relationship between human-pet interaction and loneliness in nursing home residents. These concepts included (a) environmental stimuli as factors influencing adaptation and (b) interdependence as a mode of response to the environment. The hypothesis of this study asserted that the residents of a nursing home who had greater levels of interaction with a pet program would experience less loneliness than those who had lower levels of interaction with a pet. The study used an ex post facto nonexperimental design with 65 subjects. The simplified version of the revised UCLA loneliness scale was used to measure loneliness. Reported level of human-pet interaction was measured according to a four-point scale (1 = no interaction, 4 = quite a lot of interaction). The hypothesis was supported at the p less than 0.03 level of significance. Implications for practice through organizing pet programs in situations where loneliness exists are discussed. Recommendations for future research include replicating the study using a larger sample and developing a comprehensive human-pet interaction tool.

    Although antemortem approaches in wildlife disease surveillance are common for most zoonoses, they have been used infrequently in anthrax surveillance. Classically, anthrax is considered a disease with extremely high mortality. This is because anthrax outbreaks are often detected ex post facto through wildlife or livestock fatalities or spillover transmission to humans. As a result, the natural prevalence of anthrax infection in animal populations is largely unknown. However, in the past 20 yr, antemortem serologic surveillance in wildlife has indicated that not all species exposed succumb to infection, and anthrax exposure may be more widespread than originally appreciated. These studies brought about a multitude of new questions, many of which can be addressed by increased antemortem serologic surveillance in wildlife populations. To fully understand anthrax transmission dynamics and geographic extent, it is important to identify exposure in wildlife hosts and associated factors and, in turn, understand how these influences may drive environmental reservoir dynamics and concurrent disease risk in livestock and humans. Here we review our current understanding of the serologic response to anthrax among wildlife hosts and serologic diagnostic assays used to augment traditional postmortem anthrax surveillance strategies. We also provide recommendations for the use of serology and sentinel species surveillance approaches in anthrax research and management.

    Livestock is a one of the major sources of livelihood for most of the small and marginal farmers in India, particularly for rural households who live in below poverty line. Extension interventions have long been seen as a key element for enabling farmers to obtain information and technologies that can improve their livelihoods. It is also recognized that extension is an important factor in promoting dairy development. Ex-post-facto cause to effect research design was applied in this study to trace out the impact of extension interventions in improving knowledge, attitude, adoption towards scientific dairy farming practices and improvement in milk production of dairy animal and income from dairying which will be resulted into improved livelihood of rural poor in Nadia district of West Bengal, India. Therefore, 60 dairy farmers of experimental villages who were considered as beneficiaries and 60 dairy farmers of control villages who were considered as non-beneficiaries were selected as sample for the study. It was found that beneficiaries had significantly higher score in all the five components of livelihood improvement with its all sub components, i.e., knowledge, attitude, adoption of scientific dairy farming practices, milk production per household per day and monthly income from dairying except disease control, and marketing component of adoption. Hence, it may be concluded that extension interventions had a significant impact on improving livelihood of rural dairy farmers in Nadia district of West Bengal, India.

    Based on the diathesis-stress model of anxiety, this study examined the contributions of cultural processes, perceived racial discrimination, and personality traits to social anxiety among Chinese immigrants. Further guided by the theory of intergroup anxiety, this study also adopted a context-specific approach to distinguish between participants' experience of social anxiety when interacting with European Americans versus with other Chinese in the United States. This quantitative and ex post facto study used a convenience sample of 140 first-generation Chinese immigrants. Participants were recruited through e-mails from different university and community groups across the United States. The sample includes 55 men and 82 women (3 did not specify) with an average age of 36 years old. Results showed that more social anxiety was reported in the European American context than in the Chinese ethnic context. The full models accounted for almost half the variance in anxiety in each context. Although personality accounted for the most variance, the cultural variables and discrimination contributed 14% of the unique variance in the European American context. Notably, low acculturation, high neuroticism, and low extraversion were unique contributors to social anxiety with European Americans, whereas in the Chinese ethnic context only low extraversion was a unique contributor; more discrimination was uniquely significant in both contexts. The findings suggest a need to contextualize the research and clinical assessment of social anxiety, and have implications for culturally sensitive counseling with immigrants.

    There is gap in passing rates on the standardized science assessment between European American and Hispanic American students. The purpose of this study was to examine student performance in science and the closing of the achievement gap between European American and Hispanic American students based upon receipt of an inquiry or noninquiry instruction method. Guided by the theoretical framework of constructive learning, this quantitative ex post facto research design gathered data from 8 teachers who had already implemented 1 of the 2 methods of instruction. The teachers were chosen through purposive sampling based on previous observations of instructional method and were placed into 2 groups depending upon the type of instruction: inquiry or noninquiry. Descriptive statistics were used to determine mean differences and a 2-way analysis of variance was used to determine mean differences in science test scores between European American and Hispanic American students and between the instructional methods to which they had been exposed. Results found that the inquiry instructional method was related to a significant increase in mean scores for both ethnic groups, but the achievement gap between the two groups was not closed by the inquiry instruction method. This study can promote positive social change for students by informing the efforts of educational leaders and teachers to create professional development using inquiry instruction. Students may perform higher on standardized tests when they are allowed to explore science by asking questions and answering their own questions through the collection and analysis of data.

    Wetmore, Michael J.

    The purpose of this applied dissertation was to investigate the relationship between risk factors and aeronautical decision making in the flight training environment using a quantitative, non-experimental, ex post facto research design. All 75 of the flight training accidents that involved a fatality from the years 2001-2003 were selected for study from the National Transportation Safety Board (NTSB) aviation accident database. Objective evidence from the Factual Reports was used to construct accident chains and to code and quantify total risk factors and total poor aeronautical decisions. The data were processed using correlational statistical tests at the 1% significance level. There was a statistically significant relationship between total risk factors per flight and poor decisions per flight. Liveware risks were the most prevalent risk factor category. More poor decisions were made during preflight than any other phase of flight. Pilots who made multiple poor decisions per flight had significantly higher risk factors per flight. A risk factor threat to decision making chart is presented for use by flight instructors and/or flight training organizations. The main threat to validity of this study was the NTSB accident investigation team investigative equality assumption.

    The rate of beer aging is affected by storage conditions including largely time and temperature. Although bottled beer is commonly stored for up to 1 year, sensorial damage of it is quite frequent. Therefore, a method for retrospective determination of temperature of stored beer was developed. The method is based on the determination of selected carbonyl compounds called as "aging indicators", which are formed during beer aging. The aging indicators were determined using GC-MS after precolumn derivatization with O-(2,3,4,5,6-pentaflourobenzyl)hydroxylamine hydrochloride, and their profile was correlated with the development of old flavor evolving under defined conditions (temperature, time) using both a mathematical and statistical apparatus. Three approaches, including calculation from regression graph, multiple linear regression, and neural networks, were employed. The ultimate uncertainty of the method ranged from 3.0 to 11.0 °C depending on the approach used. Furthermore, the assay was extended to include prediction of beer tendency to sensory aging from freshly bottled beer.

    In trypanosomes, the production of mRNA relies on the synthesis of the spliced leader (SL) RNA. Expression of the SL RNA is initiated at the only known RNA polymerase II promoter in these parasites. In the pathogenic trypanosome, Trypanosoma brucei, transcription factor IIB (tTFIIB) is essential for SL RNA gene transcription and cell viability, but has a highly divergent primary sequence in comparison to TFIIB in well-studied eukaryotes. Here we describe the 2.3 A resolution structure of the C-terminal domain of tTFIIB (tTFIIBC). The tTFIIBC structure consists of 2 closely packed helical modules followed by a C-terminal extension of 32 aa. Using the structure as a guide, alanine substitutions of basic residues in regions analogous to functionally important regions of the well-studied eukaryotic TFIIB support conservation of a general mechanism of TFIIB function in eukaryotes. Strikingly, tTFIIBC contains additional loops and helices, and, in contrast to the highly basic DNA binding surface of human TFIIB, contains a neutral surface in the corresponding region. These attributes probably mediate trypanosome-specific interactions and have implications for the apparent bidirectional transcription by RNA polymerase II in protein-encoding gene expression in these organisms.

  7. High speed research system study. Advanced flight deck configuration effects

    1992-01-01

    In mid-1991 NASA contracted with industry to study the high-speed civil transport (HSCT) flight deck challenges and assess the benefits, prior to initiating their High Speed Research Program (HSRP) Phase 2 efforts, then scheduled for FY-93. The results of this nine-month effort are presented, and a number of the most significant findings for the specified advanced concepts are highlighted: (1) a no nose-droop configuration; (2) a far forward cockpit location; and (3) advanced crew monitoring and control of complex systems. The results indicate that the no nose-droop configuration is critically dependent upon the design and development of a safe, reliable, and certifiable Synthetic Vision System (SVS). The droop-nose configuration would cause significant weight, performance, and cost penalties. The far forward cockpit location, with the conventional side-by-side seating provides little economic advantage; however, a configuration with a tandem seating arrangement provides a substantial increase in either additional payload (i.e., passengers) or potential downsizing of the vehicle with resulting increases in performance efficiencies and associated reductions in emissions. Without a droop nose, forward external visibility is negated and takeoff/landing guidance and control must rely on the use of the SVS. The technologies enabling such capabilities, which de facto provides for Category 3 all-weather operations on every flight independent of weather, represent a dramatic benefits multiplier in a 2005 global ATM network: both in terms of enhanced economic viability and environmental acceptability.

    The Human Gene Mutation Database (HGMD(®)) constitutes a comprehensive collection of published germline mutations in nuclear genes that underlie, or are closely associated with human inherited disease. At the time of writing (March 2017), the database contained in excess of 203,000 different gene lesions identified in over 8000 genes manually curated from over 2600 journals. With new mutation entries currently accumulating at a rate exceeding 17,000 per annum, HGMD represents de facto the central unified gene/disease-oriented repository of heritable mutations causing human genetic disease used worldwide by researchers, clinicians, diagnostic laboratories and genetic counsellors, and is an essential tool for the annotation of next-generation sequencing data. The public version of HGMD ( http://www.hgmd.org ) is freely available to registered users from academic institutions and non-profit organisations whilst the subscription version (HGMD Professional) is available to academic, clinical and commercial users under license via QIAGEN Inc.

  9. The emergence and current performance of a health research system: lessons from Guinea Bissau

    PubMed Central

    2012-01-01

    Background Little is known about how health research systems (HRS) in low-income countries emerge and evolve over time, and how this process relates to their performance. Understanding how HRSs emerge is important for the development of well functioning National Health Research Systems (NHRS). The aim of this study was to assess how the HRS in Guinea Bissau has emerged and evolved over time and how the present system functions. Methods We used a qualitative case-study methodology to explore the emergence and current performance of the HRS, using the NHRS framework. We reviewed documents and carried out 39 in-depth interviews, ranging from health research to policy and practice stakeholders. Using an iterative approach, we undertook a thematic analysis of the data. Results The research practices in Guinea Bissau led to the emergence of a HRS with both local and international links and strong dependencies on international partners and donors. The post-colonial, volatile and resource-dependent context, changes in donor policies, training of local researchers and nature of the research findings influenced how the HRS evolved. Research priorities have mostly been set by 'expatriate' researchers and focused on understanding and reducing child mortality. Research funding is almost exclusively provided by foreign donors and international agencies. The training of Guinean researchers started in the mid-nineties and has since reinforced the links with the health system, broadened the research agenda and enhanced local use of research. While some studies have made an important contribution to global health, the use of research within Guinea Bissau has been constrained by the weak and donor dependent health system, volatile government, top-down policies of international agencies, and the controversial nature of some of the research findings. Conclusions In Guinea Bissau a de facto 'system' of research has emerged through research practices and co-evolving national and

  10. A Reassessment of the Impact of Astronomy REU Programs on Female Students

    NASA Astrophysics Data System (ADS)

    Slater, Stephanie J.; Slater, T. F.

    2008-05-01

    For many years, federal agencies have enthusiastically supported Research Experiences for Undergraduates (REU) programs to engage students in research experiences to encourage them to continue to pursue astronomy career paths. Despite widespread tacit agreement that such experiences are critically important to filling the STEM career pipeline, there has been insufficient evaluation published to substantiate these impacts, with what little is described focusing on building students’ confidence and enculturation into the scientific enterprise. Upon closer inspection the data that exists, it appears that REU's may have little impact on participants’ career decisions, with the small number of those who do alter their intentions in favor of attending being balanced out by those who decide not to attend. This scenario begs the question of do REU programs create students who will go on to STEM careers or, alternatively, do REU programs simply attract students who are already pre-destined for STEM careers? This study chose to approach the problem using a mixed method, ex post facto design. Using six years of data, pre- and post- interview transcripts were compared to career decisions to develop a framework through which to further interview participants with regard to which career pathway decisions they are making. An interview process was then used to develop a new model that explained both these participants’ choices and findings in previous research. Data suggests that the nature and perceived quality of an REU experience is largely irrelevant to STEM career pursuit. For participants who were already committed to graduate studies, the REU was a means to enhance their candidacy for admissions. Those least likely to attend graduate school were those who were not committed prior to the REU. For these participants the REU served as a means to enhance their resumes for post-graduation employment.

    Dropping out of university has serious consequences not only for the student who drops out but also for the institution and society as a whole. Although this phenomenon has been widely studied, there is a need for broader knowledge of the context in which it occurs. Yet research on the subject often focuses on variables that, although they affect drop-out rates, lie beyond a university's control. This makes it hard to come up with effective preventive measures. That is why a northern Spanish university has undertaken a ex post facto holistic research study on 1,311 freshmen (2008/9, 2009/10, and 2010/11 cohorts). The study falls within the framework of the ALFA-GUIA European Project and focuses on those drop-out factors where there is scope for taking remedial measures. This research explored the possible relationship of degree drop-out and different categories of variables: variables related to the educational stage prior to university entry (path to entry university and main reason for degree choice), variables related to integration and coexistence at university (social integration, academic integration, relationships with teachers/peers and value of the living environment) financial status and performance during university studies (in terms of compliance with the program, time devoted to study, use of study techniques and class attendance). Descriptive, correlational and variance analyses were conducted to discover which of these variables really distinguish those students who drop-out from their peers who complete their studies. Results highlight the influence of vocation as main reason for degree choice, path to university entry, financial independency, social and academic adaptation, time devoted to study, use of study techniques and program compliance in the studied phenomenon.

  12. Science dual enrollment: An examination of high school students' post-secondary aspirations

    Berry, Chelsia

    The purpose of this study was to determine if participation in science dual enrollment courses influenced African American high school students' post-secondary aspirations that will lead to college attendance. The investigation examined the relationship between African American students' learning experiences and how their self-efficacy and outcome expectations impact their goal setting. The goal was to determine the impact of the following variables on African American students' plan to pursue a bachelor's or advanced degree: (a) STEM exposure, (b) Algebra 1 achievement, (c) level of science class, and (d) receiving science college credit for dual enrollment course. The social cognitive career theory framed this body of research to explore how career and academic interests mature, are developed, and are translated into action. Science dual enrollment participation is a strategy for addressing the lack of African American presence in the STEM fields. The causal comparative ex post facto research design was used in this quantitative study. The researcher performed the Kruskal-Wallis non-parametric analysis of variance and Pearson's chi-square tests to analyze secondary data from the High School Longitudinal Study first follow-up student questionnaire. The results indicate that STEM exposure and early success in Algebra 1 have a statistically significant impact on African American students' ambition to pursue a bachelor's or advanced degree. According to the Pearson's chi-square and independent sample Kruskal-Wallis analyses, level of students' science class and receiving college credit for dual enrollment do not significantly influence African American students' postsecondary aspirations.

    1994-05-01

    .90ex> }}} The ``N'' in N-body calculations has doubled every year for the last two decades. To continue this trend, the UW N-body group is working on algorithms for the fast evaluation of gravitational forces on parallel computers and establishing rigorous standards for the computations. In these algorithms, the computational cost per time step is ~ 10(3) pairwise forces per particle. A new adaptive time integrator enables us to perform high quality integrations that are fully temporally and spatially adaptive. SPH--smoothed particle hydrodynamics will be added to simulate the effects of dissipating gas and magnetic fields. The importance of these calculations is two-fold. First, they determine the nonlinear consequences of theories for the structure of the Universe. Second, they are essential for the interpretation of observations. Every galaxy has six coordinates of velocity and position. Observations determine two sky coordinates and a line of sight velocity that bundles universal expansion (distance) together with a random velocity created by the mass distribution. Simulations are needed to determine the underlying structure and masses. The importance of simulations has moved from ex post facto explanation to an integral part of planning large observational programs. I will show why high quality simulations with ``large N'' are essential to accomplish our scientific goals. This year, our simulations have N >~ 10(7) . This is sufficient to tackle some niche problems, but well short of our 5 year goal--simulating The Sloan Digital Sky Survey using a few Billion particles (a Teraflop-year simulation). Extrapolating past trends, we would have to ``wait'' 7 years for this hundred-fold improvement. Like past gains, significant changes in the computational methods are required for these advances. I will describe new algorithms, algorithmic hacks and a dedicated computer to perform Billion particle simulations. Finally, I will describe research that can be enabled by

  1. The effect of learning style on academic student success

    NASA Astrophysics Data System (ADS)

    Stackhouse, Omega N.

    The problem addressed in this study was that little was known about the impact on student academic achievement, when grouped by learning style, in a multiple intelligence based science curriculum. The larger problem was that many students were frequently unengaged and, consequently, low achieving in their science courses. This quantitative study used an ex post facto research design to better understand the impact of student learning style on the academic success of students in a Multiple Intelligence Theory based course room. Gardner's work on Multiple Intelligence served as the conceptual framework for this study. The research question for this study asked if academic instruction that employs multiple intelligence theories has a relationship with students' academic achievement differently according to their learning style group (auditory, visual, and kinesthetic). Existing data from 85 students were placed into 1 of 3 groups: (a) Auditory, (b) Visual, or (c) Kinesthetic Learning Style) using existing data from a student inventory instrument. The independent variable was existing data from student inventories of learning style and the dependent variable was existing student scores from the Physical Science End of Course Test. Existing data were taken from students that were all taught with the same strategies in similar classroom environments. The Physical Science End of Course Test was developed with stringent measures to protect validity by the developer, McGraw-Hill. Cronbach's Alpha was conducted to determine the internal reliability coefficient of the student inventory. The impact for social change is that adding to the body of knowledge regarding student learning style and science curriculum provides valuable information for teachers, administrators, and school policy makers. This will allow teachers to better prepare to engage their students' and to prepare them for their place in society.

    Purpose The purpose of this study is to examine, from the stereotype content model (SCM) perspective, the role of the competence and warmth stereotypes of older adults held by professional caregivers. Methods A quasi-experimental design, ex post facto with observational analyses, was used in this study. The cultural view on competence and warmth was assessed in 100 caregivers working in a set of six residential geriatric care units (three of them organized following a person-centered care approach and the other three providing standard geriatric care). In order to assess caregivers’ cultural stereotypical views, the SCM questionnaire was administered. To evaluate the role of caregivers’ cultural stereotypes in their professional performance as well as in older adult functioning, two observational scales from the Sistema de Evaluación de Residencias de Ancianos (assessment system for older adults residences)-RS (staff functioning and residents’ functioning) were applied. Results Caregivers’ cultural views of older adults (compared to young people) are characterized by low competence and high warmth, replicating the data obtained elsewhere from the SCM. Most importantly, the person-centered units predict better staff performance and better resident functioning than standard units. Moreover, cultural stereotyping of older adult competence moderates the effects of staff performance on resident functioning, in line with the findings of previous research. Conclusion Our results underline the influence of caregivers’ cultural stereotypes on the type of care, as well as on their professional behaviors and on older adult functioning. Caregivers’ cultural stereotypes could be considered as a central issue in older adult care since they mediate the triangle of care: caregivers/older adults/type of care; therefore, much more attention should be paid to this psychosocial care component.

  9. Testing the effect of a science-enhanced curriculum on the science achievement and agricultural competency of secondary agricultural education students

    Scope and Method of Study. The purpose of this study was to determine if a science-enhanced curriculum produced by the Center for Agricultural and Environmental Research and Training (CAERT) taught in a secondary level animal science or horticulture course would improve students' understanding of selected scientific principles significantly, when compared to students who were instructed using a traditional curriculum. A secondary purpose was to determine the effect that the science-enhanced CAERT curriculum would have on students' agricultural knowledge when compared to students who were instructed using a traditional curriculum. The design of the study was ex post facto, causal comparative because no random assignment of the treatment group occurred. Findings and Conclusions. No statistically significant difference was found between the treatment and comparison groups regarding science achievement. However, the mean score of the treatment group was slightly larger than the comparison group indicating a slightly higher achievement level; a "Small" effect size (d = .16) for this difference was calculated. It was determined that a statistically significant difference (p < .05) existed in agriculture competency scores in animal science (p = .001) and horticulture (p = .000) as a result of the treatment. Moreover, this was considered to be a "very large" effect (d = 1.18) in animal science and a "large" effect (d = .92) in horticulture. When considering student achievement in science, this study found that the use of the science-enhanced CAERT curriculum did not result in a statistically significant increase (p < .05) in student performance as determined by the TerraNova3 science proficiency examination. However, students who were instructed using the CAERT curriculum scored better overall than those who were instructed using a "traditional" curriculum.

    Research rotation is an important component in the education of a neurosurgical resident. The selection of the area of research is essential. There are many arguments in favour of selecting research projects to be close to the individual trainee's clinical interest. Studies far away from the individual's clinical interest in most cases are less productive and will not be pursued later. There are also many advantages if a cooperation is planned with other institutions. The programme director or staff members play an important role in the selection of the research project, of an appropriate laboratory or institution, and in the process of financing a research rotation.

    Introduction How can we get the public to appreciate the way scientific understanding advances via iterative research? How can we provide females and underrepresented minorities an opportunity to be involved in science early enough in their schooling to make a difference in career motivation? How can research laboratories help improve science education in our schools and prepare students with skills that they will need in the workforce? We do not have the answers to these questions. Indeed, we are only beginning to work together, as researchers and educators, on these topics. However, the Editor, upon seeing the large number of student and educator coauthors on our paper in this issue of Journal of Geophysical Research, invited us to describe our fledgling program, with the hope of stimulating dialogue on a topic of increasing interest.

    This project purports to develop a new scheme for forming consensus among alternative climate models, that give widely divergent projections as to the details of climate change, that is more intelligent than simply averaging the model outputs, or averaging with ex post facto weighting factors. The method under development effectively allows models to assimilate data from one another in run time with weights that are chosen in an adaptive training phase using 20th century data, so that the models synchronize with one another as well as with reality. An alternate approach that is being explored in parallel is the automated combination of equations from different models in an expert-system-like framework.

    2003-01-01

    All states and the District of Columbia have passed sex offender registration and community notification laws. While the specific provisions of these statutes vary, all have public safety as a primary goal. The authors discuss two recent cases heard by the United States Supreme Court that challenged the constitutionality of Alaska's and Connecticut's statutes. The laws were challenged as violations of the United States Constitution's prohibition on ex post facto laws and its Fourteenth Amendment guarantee of procedural due process. In both cases, the statutes were upheld. As it has found in challenges to sexually violent predator statutes, the Court emphasized that the registration and community notification schemes are civil and not criminal in nature. The article concludes with a discussion of possible implications for clinicians involved in evaluating or treating sex offenders.

    Social media analytics is showing promise for the prediction of financial markets. However, the true value of such data for trading is unclear due to a lack of consensus on which instruments can be predicted and how. Current approaches are based on the evaluation of message volumes and are typically assessed via retrospective (ex-post facto) evaluation of trading strategy returns. In this paper, we present instead a sentiment analysis methodology to quantify and statistically validate which assets could qualify for trading from social media analytics in an ex-ante configuration. We use sentiment analysis techniques and Information Theory measures to demonstrate that social media message sentiment can contain statistically-significant ex-ante information on the future prices of the S&P500 index and a limited set of stocks, in excess of what is achievable using solely message volumes.

    The objective of this study was to examine the article production on psychosis from the main spanish journals of psychology and psychiatry, as well as to make comparisons among them. 16 journals of psychology and 5 of psychiatry were selected and a period of revision of four years settled down (2003-2006). The sample was constituted by 183 articles. For the comparison of the journals four index were used: proportion of articles on psychosis in relation to the total of generated articles; used type of methodology; used type of sample; and aspect of the psychosis in whose investigation it is centered. The results show that little is investigated, that most of the studies is theoretical or ex- post facto, that more the frequently studied subjects are those with psychosis and that the taken care of aspects more are related to the etiology and the treatment of the disease.

    The paper addresses a number of issues regarding the extent to which trafficking may be applied to migrant domestic workers who enter under the kafala system of sponsorship in the Middle East. Migrant domestic workers are the most numerous of those mentioned in reports on trafficking for labour exploitation in the region. The discussion seeks to determine whether "trafficking" can be ex post facto, rather than ex ante? In other words, can the label of trafficking be attributed only after the worker has arrived in the receiving country and is victimized according to the principles of trafficking protocols? In addition, must there be a proven intent to traffic by agents, or can employers who harm and/or exploit them be considered as traffickers alone? Should the harm done to workers on arrival at their place of work be classified (and assisted) as victims of trafficking, or as exploited workers?

  6. Supreme Court says Air Force may dismiss HIV-positive major.

    1999-05-28

    The U.S. Supreme Court decided unanimously that the Air Force has a right to dismiss an officer convicted by a court-martial for having unprotected sex with two women without disclosing his HIV-positive status. The court overturned a decision by a military appeals court to grant the defendant extraordinary relief under the All Writs Act. The defendant appealed his administrative dismissal, fearing he would lose medication access, and asserting that his removal was an unconstitutional violation of the "ex post facto" and double jeopardy clauses. The defendant had already served time in military confinement and lost salary following his court-martial. The justices stated that other statutory relief was available, and that the officer's dismissal was purely administrative, and unrelated to his court-martial.

    This study was designed to determine strategies to raise the NCLEX-RN pass rate and lower the attrition rate in a community college nursing program. Ex-post facto data were collected from 213 former nursing student records. Qualitative data were collected from 10 full-time faculty, 30 new graduates, and 45 directors of associate degree nursing programs in Texas. The findings linked the academic variables of two biology courses and three components of the preadmission test to completion of the nursing program. A relationship was found between one biology course, the science component of the preadmission test, the HESI Exit Examination score, and the nursing skills course to passing the NCLEX-RN. Qualitative data indicated preadmission requirements, campus counselors, remediation, faculty, test-item writing, and teaching method were instrumental in completion of the program and passing the NCLEX-RN.

    The purpose of this ex post facto correlational study was to compare exit examination scores and NCLEX-RN(®) pass rates of baccalaureate nursing students who differed in level of participation in a standardized test package. Three cohort groups emerged as a standardized test package was introduced: (a) students who did not participate in a standardized test package; (b) students with two semesters of a standardized test package; and (c) students with four semesters of a standardized test package. Benner's novice-to-expert theory framed the study in the belief that students best acquire knowledge and skills through practice and reflection. Students participating in four semesters of a standardized test package demonstrated higher exit examination scores and NCLEX-RN pass rates compared with students who did not participate in this package. This study's results could inform nurse educators about strategies to facilitate nursing student success on exit examinations and the NCLEX-RN.

    Ergotism is a horrendous disease with grotesque symptoms caused by ingesting specific ergot alkaloids. Mass poisoning episodes are attributable to consumption of grain - usually rye - infected with the fungus Claviceps purpurea. By focusing on possible cases of ergotism, we re-examine Norwegian history from the sagas through to the end of the seventeenth century. Our review - not intended to be exhaustive, or ex post facto to assign medical or psychiatric labels - draws attention to the very real possibility that many remarkable medical cases may have been the result of the ingestion of highly poisonous and psychoactive food substances. Where possible we highlight explanations given at the time - often rooted in religion or demonology - to explain the disease.

    2008-01-01

    An ex post facto study was conducted to investigate treatment outcomes for 80 women and 168 children admitted into a residential substance-abuse treatment program. The results indicated childhood emotional neglect is a barrier for remaining in and completing treatment for African-American women with comorbid psychological disorders but not for those with crack cocaine dependent disorders. African-American women with comorbid psychological disorders were also three times more likely to dropout of treatment. In addition, there were relatively few differences for between drug-exposed and nonexposed children. However, the results indicated that children of substance-abusing women who completed treatment were more likely to have behavioral problems, to receive early intervention services, and to have mothers as legal guardians by the end of treatment. Implications for gender-specific interventions for African-American women and their children in residential treatment are discussed.

    1996-12-01

    Anxiety and self-efficacy in mathematics as a function of sex and mathematical background were investigated. This study employed an ex post facto 2 x 2 factorial design in which sex and mathematical background were classification variables. It was predicted that men would report lower anxiety scores and higher self-efficacy scores than women and that students with a high mathematical background would report lower anxiety scores and higher self-efficacy scores than those with a low background in mathematics. An interaction between sex and mathematical background was also predicted. 51 subjects were given the revised Mathematics Anxiety Scale and the Mathematics Self-efficacy Scale. Results supported the hypotheses with respect to background in mathematics for anxiety in mathematics, and all of the hypotheses were supported for self-efficacy in mathematics.

  12. OUTSOURCING ETHICAL DILEMMAS: REGULATING INTERNATIONAL SURROGACY ARRANGEMENTS.

    PubMed

    Fenton-Glynn, Claire

    2016-01-01

    This article argues that the English legislative regime is ineffective in regulating international surrogacy, particularly with regard to commercial payments. It suggests that if English law views surrogacy as exploitative, we have a responsibility to protect women both in England and abroad, and the only way to do so effectively is to create a domestic system of regulation that caters adequately for the demand in this country. This requires a system of authorisation for surrogacy before it is undertaken; ex-post facto examinations of agreements completed in other jurisdictions, after the child is already living with the commissioning parents, cannot be seen as an acceptable compromise, as authorisation will inevitably be granted in the child's best interests.

    James Antaki and a group of researchers from the University of Pittsburgh School of Medicine used many elements of the Technology Utilization Program while looking for a way to visualize and track material points within the heart muscle. What they needed were tiny artificial "eggs" containing copper sulfate solution, small enough (about 2 mm in diameter) that they would not injure the heart, and large enough to be seen in Magnetic Resonance Imaging (MRI) images; they also had to be biocompatible and tough enough to withstand the beating of the muscle. The group could not make nor buy sufficient containers. After reading an article on microspheres in NASA Tech Briefs, and a complete set of reports on microencapsulation from the Jet Propulsion Laboratory (JPL), JPL put Antaki in touch with Dr.Taylor Wang of Vanderbilt University who helped construct the myocardial markers. The research is expected to lead to improved understanding of how the heart works and what takes place when it fails.

    The main objective of the structures group is to provide quality aerospace research with the Center for Aerospace Research - A NASA Center for Excellence at North Carolina Agricultural and Technical State University. The group includes dedicated faculty and students who have a proven record in the area of structures, in particular space structures. The participating faculty developed accurate mathematical models and effective computational algorithms to characterize the flexibility parameters of joint dominated beam-truss structures. Both experimental and theoretical modelling has been applied to the dynamic mode shapes and mode frequencies for a large truss system. During the past few months, the above procedures has been applied to the hypersonic transport plane model. The plane structure has been modeled as a lumped mass system by Doctor Abu-Saba while Doctor Shen applied the transfer matrix method with a piecewise continuous Timoshenko tapered beam model. Results from both procedures compare favorably with those obtained using the finite element method. These two methods are more compact and require less computer time than the finite element method. The group intends to perform experiments on structural systems including the hypersonic plane model to verify the results from the theoretical models.

    1985-01-01

    Research efforts span three general areas of glass science: glass refining, gel-derived glasses, and nucleation and crystallization of glasses. Gas bubbles which are present in a glass product are defects which may render the glass totally useless for the end application. For example, optical glasses, laser host glasses, and a variety of other specialty glasses must be prepared virtually defect free to be employable. Since a major mechanism of bubble removal, buoyant rise, is virtually inoperative in microgravity, glass fining will be especially difficult in space. On the other hand, the suppression of buoyant rise and the ability to perform containerless melting experiments in space allows the opportunity to carry out several unique bubble experiments in space. Gas bubble dissolution studies may be performed at elevated temperatures for large bubbles with negligible bubble motion. Also, bubble nucleation studies may be performed without the disturbing feature of heterogeneous bubble nucleation at the platinum walls. Ground based research efforts are being performed in support of these potential flight experiments.

    Work performed by the University of Alabama in Huntsville's (UAH) Center for Applied Optics (CAO) entitled Atomic Research is documented. Atomic oxygen (AO) effects on materials have long been a critical concern in designing spacecraft to withstand exposure to the Low Earth Orbit (LEO) environment. The objective of this research effort was to provide technical expertise in the design of instrumentation and experimental techniques for analyzing materials exposed to atomic oxygen in accelerated testing at NASA/MSFC. Such testing was required to answer fundamental questions concerning Space Station Freedom (SSF) candidate materials and materials exposed to atomic oxygen aboard the Long-Duration Exposure Facility (LDEF). The primary UAH task was to provide technical design, review, and analysis to MSFC in the development of a state-of-the-art 5eV atomic oxygen beam facility required to simulate the RAM-induced low earth orbit (LEO) AO environment. This development was to be accomplished primarily at NASA/MSFC. In support of this task, contamination effects and ultraviolet (UV) simulation testing was also to be carried out using NASA/MSFC facilities. Any materials analysis of LDEF samples was to be accomplished at UAH.

  19. A theory of requirements definition in engineering design

    NASA Astrophysics Data System (ADS)

    Eodice, Michael Thomas

    2000-10-01

    Traditional requirements-definition activities begin with the engineer or design team performing a needs-analysis to identify user requirements. Needs-analysis is generally subjective, and varies according to the composition and experience of the design team. Systematic procedures for defining and ranking requirements are necessary to consolidate the foundation on which the design process is predicated, and to enhance its outcome by providing the designer with a consistent, reliable approach to product development. As a first step towards developing such procedures, research was conducted at Stanford University using empirical data from a NASA spaceflight experiment that flew aboard Space Shuttle mission STS-90 (April 1998). This research was accomplished using ex post facto data analysis. This researcher served in the central role of Experiment Manager for the spaceflight experiment, and acted as a participant-observer while conducting formal research. To better understand requirement structure and evolution, individual requirements were decomposed using AND/OR graphs. The AND/OR graph data structure illustrates requirements evolution, and reveals that the original requirement is often met by fulfilling a series of sub-requirements that are easier to implement. Early in the product life cycle, many hundreds of potential needs were identified; however, it was a smaller subset of these initial needs that were realized in the final product. Based on analysis of a large group of requirements, it was observed that two critical components for any individual requirement were: (1) a stated need, and (2) an advocate to implement the need. Identification of need, or needs-analysis, although a necessary condition, is insufficient to ensure that a stated need evolves into a formal requirement. Equally important to the concept of requirements-definition is the notion of advocacy. Early in the product development cycle of the of the NASA experiment, many potential needs were

    This paper examines what is important about talk between learners during school science and, having identified this, suggests how we can ensure that what we consider important happens. By looking at the interaction between teachers and learners talking about science, it is possible to indicate ways in which learners can be helped to continue this learning conversation with one another when teacher support is withdrawn. Strategies for teaching and learning are examined. The paper reports on the findings of a research project designed to teach children how to negotiate their ideas about science concepts through rational dialogue. Children's development of scientific concepts in classrooms is undertaken through structured activity and mediated through oral language. Children must move forward simultaneously in their use of specialized vocabulary and in their understanding of current scientific explanations, models and ideas. New language and new ways of using language are learned by doing, which means for children, primarily speaking and listening. Children's understanding of science can benefit from teaching them to understand that spoken language is a powerful tool for thinking together.

    Gado, Issaou

    The Republic of Benin (West Africa) undertook a nationwide curriculum reform that put an emphasis on inquiry-based instructional practices. Little, if any, research has been conducted to explore factors that could be related to teachers' orientation toward inquiry instructional practices. The purpose of this research study was to investigate factors and concerns that determine Benin elementary school teachers' orientation toward the use of inquiry-based instruction in the teaching of science. The study followed a naturalistic inquiry methodology combining a correlational ex post facto design and an observational case-study design. The theory of Planned Behavior was the conceptual framework used to design the study. Two hundred (N = 200) elementary school teachers and three (n = 3) case study participants were purposively selected. Data was gathered via the Revised Science Attitude Scale (Thompson & Shrigley, 1986), the Science Teachers' Ideological Preference Scale (Jones & Harty, 1978), open-ended questions, interviews, and classroom observations using audiorecorders, videorecorders, and the researcher-contextualized version of the Observational System for the Analysis of Classroom Instruction (Hough, 1966). Qualitative and quantitative data provided a deeper understanding of participants' responses. Quantitative measures indicated that Benin elementary school teachers have positive attitudes toward school science, significant positive orientation toward both inquiry-based instruction and traditional non inquiry-based instruction, and higher orientation toward inquiry-based instruction than traditional non inquiry-based instruction. Attitude toward handling materials for investigations was found to significantly contribute to the prediction of participants' inquiry orientation. Qualitative analyses of participants' responses indicated that the expectations of educational leaders, individual motivation to comply with the program, a perceived control of the

The treatment variable was Modeling Instruction and the control variable was traditional lecture instruction. The Treatment Group consisted of participants in Physical World Concepts who received Modeling Instruction. The Control Group consisted of participants in Physical Science who received traditional lecture instruction. The dependent variable was gains scores on the Force Concepts Inventory (FCI). The participants for this study were 133 students each in both the Treatment and Control Groups (n = 266), who attended a public, high school in rural middle Tennessee. The participants were administered the Force Concepts Inventory (FCI) prior to being taught the mechanics of physics. The FCI data were entered into the computer-based Statistical Package for the Social Science (SPSS). Two independent samples t-tests were conducted to answer the research questions. There was a statistically significant difference between the treatment and control groups concerning the instructional method. Modeling Instructional methods were found to be effective in increasing the academic achievement of students in high school physics. There was no statistically significant difference between FCI gains scores for gender. Gender was found to have no effect on the academic achievement of students in high school physics classes. However, even though there was not a statistically significant difference, female students' gains scores were higher than male students' gains scores when Modeling Instructional methods of teaching were used. Based on these findings, it is recommended

  7. The effects of integrated mathematics/science curriculum and instruction on mathematics achievement and student attitudes in grade six

    Hill, Mary Denise

    The purpose of this study was to determine whether integrating mathematics and science curriculum and teaching practices significantly improves achievement in mathematics and attitudes towards mathematics among sixth grade students in South Texas. The study was conducted during the 2001--2002 school year. A causal-comparative ex post facto research design was used to explore the effects of integrated mathematics and science classrooms compared to classrooms of traditional, isolated mathematics and science teaching practices on student achievement and student attitudes. Achievement was based on the Spring 2002 Mathematics portion of the standardized Texas Assessment of Academic Skills (TAAS) Texas Learning Index (TLI) scores and individual student's mathematics Grade Point Average (GPA). Measurement of student attitudes was based on the results of the Integrated Mathematics Attitudinal Survey (IMAS), created by the researcher for this study. The sample population included 349 Grade 6 mathematics students attending one middle school involved in a pilot program utilizing integrated mathematics/science curriculum and teaching practices in a South Texas urban school district. The research involved 337 of the 349 sixth grade students to study the effects of mathematics/science curriculum and teaching practices on achievement and 207 of the 349 sixth grade students to study the effects of mathematics/science curriculum on attitudes concerning mathematics. The data were analyzed using chi square analyses, independent samples t-tests, and the analysis of variance (ANOVA). Statistical significance was determined at the .05 level of significance. Significant relationships were found when analyzing the proficiency of mathematics skills and individual growth of mathematics achievement. Chi square analyses indicated that the students in the integrated mathematics/science classrooms were more likely to exhibit individual growth and proficiency of mathematics skills based on the

  9. The relationship between selected standardized test scores and performance in advanced placement math and science exams: Analyzing the differential effectiveness of scores for course identification and placement

    NASA Astrophysics Data System (ADS)

    Urbina, Josue N.

    There is a national need to increase the STEM-related workforce. Among factors leading towards STEM careers include the number of advanced high school mathematics and science courses students complete. Florida's enrollment patterns in STEM-related Advanced Placement (AP) courses, however, reveal that only a small percentage of students enroll into these classes. Therefore, screening tools are needed to find more students for these courses, who are academically ready, yet have not been identified. The purpose of this study was to investigate the extent to which scores from a national standardized test, Preliminary Scholastic Assessment Test/ National Merit Qualifying Test (PSAT/NMSQT), in conjunction with and compared to a state-mandated standardized test, Florida Comprehensive Assessment Test (FCAT), are related to selected AP exam performance in Seminole County Public Schools. An ex post facto correlational study was conducted using 6,189 student records from the 2010 - 2012 academic years. Multiple regression analyses using simultaneous Full Model testing showed differential moderate to strong relationships between scores in eight of the nine AP courses (i.e., Biology, Environmental Science, Chemistry, Physics B, Physics C Electrical, Physics C Mechanical, Statistics, Calculus AB and BC) examined. For example, the significant unique contribution to overall variance in AP scores was a linear combination of PSAT Math (M), Critical Reading (CR) and FCAT Reading (R) for Biology and Environmental Science. Moderate relationships for Chemistry included a linear combination of PSAT M, W (Writing) and FCAT M; a combination of FCAT M and PSAT M was most significantly associated with Calculus AB performance. These findings have implications for both research and practice. FCAT scores, in conjunction with PSAT scores, can potentially be used for specific STEM-related AP courses, as part of a systematic approach towards AP course identification and placement. For courses with

  5. Predictors of Associate's Degree Completion in Engineering and Engineering Technologies

    NASA Astrophysics Data System (ADS)

    Reys-Nickel, Lynsey L.

    The purpose of this ex post facto study was to describe completers and non-completers of associate's degree programs in engineering and engineering technologies and determine whether and to what extent completion in these programs is a function of selected student-related variables and institutional variables. Data from the 2004/2009 Beginning Postsecondary Students Longitudinal Study (BPS: 04/09) of associate's degree completers and non-completers in engineering and engineering technologies were accessed and analyzed through PowerStats, a web-based data analysis tool from National Center for Education Statistics (NCES). Descriptive data indicated that, proportionally, engineering and engineering technologies completers were mostly White, married, middle income, employed part-time, enrolled full-time, did not hold a high school diploma or certificate, completed Trigonometry/Algebra II, had a father who's highest education level was an associate's degree, but did not know their mother's highest level of education, completed remedial coursework, and started college with the goal of earning an associate's degree. While more males enrolled in the programs, males and females demonstrated similar completion rates, proportionally--with females showing a slightly higher percentage of completion. Results from the logistic regression further indicated that the variables significant to completion in associate's degree programs in engineering and engineering technologies were gender and enrollment size. Findings suggested that female students were more likely to earn the degree, and that the larger the institution, the more likely the student would become a completer. However, since a major limitation of the study was the small weighted sample size, the results of the study are inconclusive in terms of the extent to which the findings can be generalized to the population of students in associate's degree programs in engineering and engineering technologies.

  6. Assessing the Effectiveness of E-learning Integration in College Physics in the Alamo Community Colleges District

    NASA Astrophysics Data System (ADS)

    Zhou, Qiaoying

    Academic achievement and student participation in physics are lower than desired. Research has shown that there is a shortage of college students entering science and technology fields such as physics. E-learning may provide the technology-oriented Net Generation learner an option for taking courses such as physics in a course modality with which they are most comfortable thus garnering more participation and higher academic achievement. A quantitative ex-post facto study was performed to compare face-to-face and E-learning modalities on course completion and physics achievement for an entire introductory physics course. The theoretical framework for this study was based on the constructivist theory of education that implies a student-centered learning process. The sample consisted of 116 students enrolled in introductory physics courses at four 2-year community colleges in Texas. Course completion, SAT scores, Force Concept Inventory examination scores, as well as demographic information and employment information were examined. Linear and ordinal multiple regression analysis were used to determine if course modality is predictive of physics achievement while controlling for general scholastic aptitude, current employment, the presence of children in the home, and teacher evaluations. The results showed that students in the E-learning course performed better on the Force Concept Inventory than those in the traditional course both in the multiple regression analysis, beta = .61, p < .001, and in the ordinal regression analysis, Wald(1) = 18.83, p < .001. A chi-square test was used to determine if course completion rates differ between students in the two course modalities. The results showed no difference in course completion rates between students in the two course modalities, chi 2(1, n = 116) = 1.02, p = .312. It was concluded that students in an E-learning course modality had higher physics achievement but were no more likely to complete the introductory

  7. The educational function of an astronomy REU program as described by participating women

    Slater, Stephanie Jean

    The long-running REU-program is tacitly intended to increase retention and provide "an important educational experience" for undergraduates, particularly women, minorities and underrepresented groups. This longitudinal, two-stage study was designed to explore the ways in which REUs acted as educational experiences for 51 women in the field of astronomy, in an attempt to develop a theory of experience related to the REU. Stage-1 consisted of an ex post facto analysis of data collected over 8 years, including multiple interviews with each participant during their REU, annual open-ended alumni surveys, faculty interviews, and extensive field notes. All data were analyzed using a theoretical framework of continuity and interaction, in a search for transformative experiences. Four findings emerged, related to developing understandings of the nature of professional scientific work, the scientific process, the culture of academia, and an understanding of the "self." Analysis provided an initial theory that was used to design the Stage-2 interview protocol. In Stage-2, over 10 hours of interviews were conducted with 8 participants selected for their potential to disconfirm the initial theory. Results indicate that the REU provided a limited impact in terms of participants' knowledge of professional astronomy as a largely computer-based endeavor. The REU did not provide a substantive educational experience related to the nature of scientific work, the scientific process, the culture of academia, participants' conceptions about themselves as situated in science, or other aspects of the "self". Instead, the data suggests that these women began the REU with pre-existing and remarkably strong conceptions in these areas, and that the REU did not function to alter those states. These conceptions were frequently associated with other mentors/scientist interactions, from middle school into the undergraduate years. Instructors and family members also served as crucial forces in

    The long-running REU program is tacitly intended to increase retention and provide "an important educational experience" for undergraduates, particularly women, minorities and underrepresented groups. This 8-year, two-stage study was designed to explore the ways in which the REU acted as an educational experience for 51 women from a single scientific discipline. This paper describes the results of that analysis in two sections. The first section describes the results from an ex post facto longitudinal data analysis. This data included multiple interviews with each participant during their REU, annual open-ended alumni surveys, faculty interviews, and extensive field notes, over an 8-year period. As a result of this analysis, four themes emerged, related to developing understandings of the nature of professional scientific work, the nature of the scientific process, the culture of academia, and finally, an understanding of the "self." This analysis served as an initial theory that was used to design the second stage, interview protocol. In the second stage over 10 hours of interviews with 8 participants were conducted and analyzed. These 8 participants were selected to represent a variety of career stages, and for their potential to disconfirm the initial theory. Analysis of this interview data failed to provide disconfirming evidence. Results from this study indicate that the REU did not provide a substantive educational experience related to the nature of scientific work, the scientific process, or the culture of academia. Results further indicated that the REU did not serve to transform participants' conceptions about themselves as situated in science, and learning gains with regard to other aspects of the self, were somewhat limited. Instead, the data suggests that these women arrived at the REU with pre-existing and remarkably strong conceptions in these areas, and that the REU did not functional to alter those states. These conceptions were frequently the

    Purpose. The purpose of this study was to identify, according to the Productivity Environment Preference Survey (PEPS) instrument, which learning-style domains (environmental, emotional, sociological, and physiological) were favored among Latino/Hispanic community college students enrolled in introductory biology classes in a large, urban community college. An additional purpose of this study was to determine whether statistically significant differences existed between the learning-style preferences and the demographic variables of age, gender, number of prior science courses, second language learner status, and earlier exposure to scientific information. Methodology. The study design was descriptive and ex post facto. The sample consisted of a total of 332 Latino/Hispanic students enrolled in General Biology 3. Major findings. The study revealed that Latino/Hispanic students enrolled in introductory biology at a large urban community college scored higher for the learning preference element of structure. Students twenty-five years and older scored higher for the learning preference elements of light, design, persistence, responsibility, and morning time (p <= 0.05). Females scored higher in the preference elements of (a) light, (b) temperature (warmth), (c) authority and (d) auditory (p <= 0.05). Significant differences were found for the elements of sound, warmth, motivation, several ways, and intake between the students with no prior science coursework and those who completed more than one (p <= 0.05). No significant learning-style preferences were found between second English language learners and those who learned English as their primary language (p <= 0.05). Students who frequently read science articles scored higher for the elements of motivation, persistence, responsibility, and tactile (p <= 0.05). Conclusions and recommendations. The conclusions were that Latino/Hispanic students need detailed guidance and clearly stated course objectives. The

    2013-12-01

    For more than two decades, federal agencies have been enthusiastically supporting summer research experiences for undergraduates. These REU programs are tacitly intended to increase retention and provide "an important educational experience" for undergraduates, particularly women, minorities and underrepresented groups. Numerous authors (viz., Laursen, Lopatto, Dolan, among many others) have enthusiastically described positive impacts of summer REU programs from exit interview data. These results include enhanced persistence to pursue STEM careers and confirmed desire to attend graduate school in the field targeted by a particular REU. Perhaps surprisingly, negative student experiences are rarely described in the scholarly literature, but do appear in more informal publications (viz., Gueterma, 2007). One wonders how REU alumni, looking back over their entire collective portfolio of experiences, now perceive the educational value of their REU experience relative to their other educational experiences. To obtain a backwards-looking, reflective description from REU alumni on the value of their REU experiences, we conducted a 10-year, two-stage study was designed to explore the ways in which the REU acted as an educational experience for 51 women from a single geoscience sub-discipline. The first phase was an ex post facto longitudinal analysis of data, including multiple interviews with each participant during their REU, annual open-ended alumni surveys, faculty interviews, and extensive field notes, over a 10-year period. This analysis informed the second phase, a clinical interview. Over 10 hours of interviews with 8 participants were conducted and analyzed. These 8 participants were selected to represent a variety of career stages, and for their potential to reflect on a wide variety of educational experiences. Results from the interviews, done many years after their REU experience, indicate that the interviewees' REU did not provide a substantive educational

  11. Involvement in research without compromising research quality.

    PubMed

    Stewart, Ruth; Liabo, Kristin

    2012-10-01

    Health research funders in the UK now ask applicants to state how their research will involve patients and members of the public. Such involvement can help with questions that researchers repeatedly face: about improving trial recruitment, response rates and follow-up. Patient and Public Involvement (PPI) in research is usually presented in the form of a ladder, from a low rung where studies are led by researchers with no patient involvement, to a high rung where studies are patient-led. This hierarchy does not sit well with many clinicians and academics whose expertise appears to have been downgraded. This article argues that research quality and relevance are optimised when patient expertise is integrated with researchers' and policy-makers' expertise, and each role acknowledged and valued, illustrated by an alternative model for PPI which places research and expertise at the centre of the involvement enterprise.

In addition, the Data Seal of Approval (DSA) and WDS have set up core certification mechanisms for trusted digital repositories in 2009, which are increasingly recognized as de facto standards. While DSA emerged in Europe in the Humanities and Social Sciences, WDS started as an international initiative with historical roots in the Earth and Space Sciences. Their catalogues of requirements and review procedures are based on the same principles of openness, transparency. A unique feature of the DSA and WDS certification is that it strikes a balance between simplicity, robustness and the effort required to complete. A successful international cross-project collaboration was initiated between WDS and DSA under the umbrella of the Research Data Alliance (RDA), an international initiative started in 2013 to promote data interoperability which provided a useful and neutral forum. A joint working group was established in early 2014 to reconcile and simplify the array of certification options and improve and stimulate core certification for scientific data services. The outputs of this collaboration are a Catalogue of Common Requirements (https://goo.gl/LJZqDo) and a Catalogue of Common Procedures (https://goo.gl/vNR0q1) which will be implemented jointly by WDS and DSA.

    2017-01-01

    A survey in the United States revealed that an alarmingly large percentage of university psychologists admitted having used questionable research practices that can contaminate the research literature with false positive and biased findings. We conducted a replication of this study among Italian research psychologists to investigate whether these findings generalize to other countries. All the original materials were translated into Italian, and members of the Italian Association of Psychology were invited to participate via an online survey. The percentages of Italian psychologists who admitted to having used ten questionable research practices were similar to the results obtained in the United States although there were small but significant differences in self-admission rates for some QRPs. Nearly all researchers (88%) admitted using at least one of the practices, and researchers generally considered a practice possibly defensible if they admitted using it, but Italian researchers were much less likely than US researchers to consider a practice defensible. Participants’ estimates of the percentage of researchers who have used these practices were greater than the self-admission rates, and participants estimated that researchers would be unlikely to admit it. In written responses, participants argued that some of these practices are not questionable and they have used some practices because reviewers and journals demand it. The similarity of results obtained in the United States, this study, and a related study conducted in Germany suggest that adoption of these practices is an international phenomenon and is likely due to systemic features of the international research and publication processes.

    The research plan was initially intended to contain the information needed to evaluate the U.S. Environmental Protection Agency (EPA) Arctic Contaminant Research Program (ACRP). The scientific aspects of the proposed research form the main body of the document and focus on objectives of the specific research components, current literature, approach, and rationale. The ACRP has three major components: (1) extensive sampling of lichens, mosses, and soils to provide a spatial understanding of the status and extent of contaminants present in arctic ecosystems, (2) lake sediment research to evaluate the source and history of arctic contaminant inputs, and (3) food web research to evaluate the possible effects of atmospherically transported pollutants on arctic food webs. The research plan will be used to provide a framework for the ACRP, based on the preliminary studies done to date and will be implemented over the next five years. The Program will undergo additional peer reviews at two-year intervals in the future.

    PubMed

    Taylor, Ruth; Thomas-Gregory, Annette

    2015-06-10

    This article describes case study research for nursing and healthcare practice. Case study research offers the researcher an approach by which a phenomenon can be investigated from multiple perspectives within a bounded context, allowing the researcher to provide a 'thick' description of the phenomenon. Although case study research is a flexible approach for the investigation of complex nursing and healthcare issues, it has methodological challenges, often associated with the multiple methods used in individual studies. These are explored through examples of case study research carried out in practice and education settings. An overview of what constitutes 'good' case study research is proposed.

  5. The qualitative research proposal.

    PubMed

    Klopper, H

    2008-12-01

    Qualitative research in the health sciences has had to overcome many prejudices and a number of misunderstandings, but today qualitative research is as acceptable as quantitative research designs and is widely funded and published. Writing the proposal of a qualitative study, however, can be a challenging feat, due to the emergent nature of the qualitative research design and the description of the methodology as a process. Even today, many sub-standard proposals at post-graduate evaluation committees and application proposals to be considered for funding are still seen. This problem has led the researcher to develop a framework to guide the qualitative researcher in writing the proposal of a qualitative study based on the following research questions: (i) What is the process of writing a qualitative research proposal? and (ii) What does the structure and layout of a qualitative proposal look like? The purpose of this article is to discuss the process of writing the qualitative research proposal, as well as describe the structure and layout of a qualitative research proposal. The process of writing a qualitative research proposal is discussed with regards to the most important questions that need to be answered in your research proposal with consideration of the guidelines of being practical, being persuasive, making broader links, aiming for crystal clarity and planning before you write. While the structure of the qualitative research proposal is discussed with regards to the key sections of the proposal, namely the cover page, abstract, introduction, review of the literature, research problem and research questions, research purpose and objectives, research paradigm, research design, research method, ethical considerations, dissemination plan, budget and appendices.

    PubMed Central

    Issenberg, S. Barry; Cohen, Elaine R.; Barsuk, Jeffrey H.; Wayne, Diane B.

    2012-01-01

    Medical education research contributes to translational science (TS) when its outcomes not only impact educational settings, but also downstream results, including better patient-care practices and improved patient outcomes. Simulation-based medical education (SBME) has demonstrated its role in achieving such distal results. Effective TS also encompasses implementation science, the science of health-care delivery. Educational, clinical, quality, and safety goals can only be achieved by thematic, sustained, and cumulative research programs, not isolated studies. Components of an SBME TS research program include motivated learners, curriculum grounded in evidence-based learning theory, educational resources, evaluation of downstream results, a productive research team, rigorous research methods, research resources, and health-care system acceptance and implementation. National research priorities are served from translational educational research. National funding priorities should endorse the contribution and value of translational education research.

  7. Life After Research Misconduct.

    PubMed

    Galbraith, Kyle L

    2017-02-01

    Research misconduct is a serious violation of a scientific community's ethical standards. Scientists who commit research misconduct typically face corrective actions from employers and funding agencies, as well as significant professional stigma. Unfortunately, there is little systematic data about the post-misconduct career of these guilty parties. Through a review of Office of Research Integrity (ORI) case summaries, I identified a pool of 284 researchers who engaged in research misconduct and were subject to ORI corrective actions. To assess the prevalence of post-misconduct research activities for these scientists, I searched publicly available databases and online resources for evidence of post-misconduct research activities (such as publications and federal research support).

  12. [Research in tropical medicine].

    PubMed

    Dumas, Michel; Preux, Pierre-Marie

    2013-10-01

    In France, research in tropical medicine is carried out by the Institute for Research and Development (IRD), university-affiliated institutes, and other research organizations such as INSERM, CNRS and the Pasteur Institute. Currently, this research is highly fragmented and therefore inefficient. As a result, despite significant financial means, French research in this field is not sufficiently competitive. This research activity should be coordinated by creating a "federation ", that would 1) facilitate the sharing of material and human resources, thereby improving efficiency and resulting in cost savings; 2) valorize French research in tropical medicine and its expert know-how, thus favoring the nomination of French experts in large international research programs (French experts in tropical medicine are currently under-recognized); 3) attract young researchers from France and elsewhere; and 4) adapt to the ongoing demographic and economic evolution of tropical countries. The creation of a Federation of French researchers would also make research in tropical medicine more visible. The objectives to which it leads already must include 1) a better understanding of the priorities of countries in the southern hemisphere, taking into account the social, cultural and economic contexts and ensuring the consistency of current and future projects ; 2) strengthening of research networks in close and equal partnership with researchers in the southern hemisphere, with pooling of resources (scientific, human and material) to reach the critical mass required for major projects ; 3) promoting the emergence of centers of excellence for health research in tropical countries ; and 4) contributing more effectively to training, because there can be no training without research, and no research without training This consolidation will help to empower research in tropical medicine, as in other Western countries, and will allow France to recover the place it deserves.

  15. Rocket Propulsion Research at Lewis Research Center

    NASA Technical Reports Server (NTRS)

    Dawson, Virginia P.

    1992-01-01

    A small contingent of engineers at NASA Lewis Research Center pioneered in basic research on liquid propellants for rockets shortly after World War II. Carried on through the 1950s, this work influenced the important early decisions made by Abe Silverstein when he took charge of the Office of Space Flight Programs for NASA. He strongly supported the development of liquid hydrogen as a propulsion fuel in the face of resistance from Wernher von Braun. Members of the Lewis staff played an important role in bringing liquid hydrogen technology to the point of reliability through their management of the Centaur Program. This paper demonstrates how the personality and engineering intuition of Abe Silverstein shaped the Centaur program and left a lasting imprint on the laboratory research tradition. Many of the current leaders of Lewis Research Center received their first hands-on engineering experience when they worked on the Centaur program in the 1960s.

    2014-01-01

    Research funding from public and private sources has reached an all-time low. Economic conditions, sequestration, and a trend of low award success rates have created an imbalance between the supply of highly qualified research investigators and the availability of critically necessary research dollars. This grim environment continues to hinder the success of established investigators and deter potential investigators from joining the research workforce. Without action and support of innovative science, the future of the US health care system is in jeopardy, and its leadership role in medical research will decrease. This work discusses the effects of the decline in research funding, the plight of kidney research, and the impact of the American Society of Nephrology Grants Program on scientists. The ASN also calls on the entire nephrology community to rejuvenate the research environment, improve the lives of millions of people with kidney disease, and ultimately, find a cure. PMID:24652790

  14. Human research subjects as human research workers.

    PubMed

    Lynch, Holly Fernandez

    2014-01-01

    Biomedical research involving human subjects has traditionally been treated as a unique endeavor, presenting special risks and demanding special protections. But in several ways, the regulatory scheme governing human subjects research is counter-intuitively less protective than the labor and employment laws applicable to many workers. This Article relies on analogical and legal reasoning to demonstrate that this should not be the case; in a number of ways, human research subjects ought to be fundamentally recast as human research workers. Like other workers protected under worklaw, biomedical research subjects often have interests that diverge from those in positions of control but little bargaining power for change. Bearing these important similarities in mind, the question becomes whether there is any good reason to treat subjects and protected workers differently as a matter of law. With regard to unrestricted payment, eligibility for a minimum wage, compensation for injury, and rights to engage in concerted activity, the answer is no and human subjects regulations ought to be revised accordingly.

    Basics for proper research are good ideas, know how and adequate resources. Essential to accomplish a research project in an efficient way is thorough planning. A research project can be divided in four organizational units. Writing of the protocol, which includes details about all relevant aspects, e.g. the research question, study design, time table and budget, second, details on data collection, third, data analysis and fourth, writing a report or manuscript for publication. A thoroughly developed protocol facilitates the communication between all involved persons and permits an efficient management of a research project.

  3. Neoliberalism, Performativity and Research

    NASA Astrophysics Data System (ADS)

    Roberts, Peter

    2007-07-01

    This paper provides a critical analysis of New Zealand's Performance Based Research Fund (PBRF). The first section sketches the development and implementation of the PBRF. The second section evaluates the scheme, concentrating on three themes: the relationship between privatization, competition and research performance; the standardization of research; and motivations for research. The paper acknowledges the thorough work completed by the Tertiary Education Advisory Commission and other policy groups in laying the foundation for the adoption of performance-based research funding in New Zealand. It is argued, however, that when viewed in its larger context, the PBRF constitutes a continuation of neoliberal trends already well established in New Zealand's tertiary education system.

    The ability to critique research is a valuable skill that is fundamental to a perioperative nurse's ability to base his or her clinical practice on evidence derived from research. Criteria differ for critiquing a quantitative versus a qualitative study (ie, statistics are evaluated in a quantitative study, but not in a qualitative study). This article provides on guidelines for assessing qualitative research. Excerpts from a published qualitative research report are summarized and then critiqued. Questions are provided that help evaluate different sections of a research study (eg, sample, data collection methods, data analysis).

    Qualitative research methods are a robust tool for chaplaincy research questions. Similar to much of chaplaincy clinical care, qualitative research generally works with written texts, often transcriptions of individual interviews or focus group conversations and seeks to understand the meaning of experience in a study sample. This article describes three common methodologies: ethnography, grounded theory, and phenomenology. Issues to consider relating to the study sample, design, and analysis are discussed. Enhancing the validity of the data, as well reliability and ethical issues in qualitative research are described. Qualitative research is an accessible way for chaplains to contribute new knowledge about the sacred dimension of people's lived experience.

  9. Being a qualitative researcher.

    PubMed

    Holloway, Immy; Biley, Francis C

    2011-07-01

    This article, from a keynote address, is the result of some of the things which I learned about qualitative research during my many years of doing and teaching it. The main point I make is that qualitative researchers should present a good story which is based on evidence but focused on meaning rather than measurement. In qualitative inquiry, the researchers' selves are involved, their experiences become a resource. Researchers cannot distance themselves from the other participants, although they cannot fully present their meaning and experience. I also discuss voice, paradigm, and innovation as potentially problematic issues in qualitative research. These are terms often used but not always examined for their meaning in qualitative inquiry. If researchers are aware and sensitive, rather than overemotional or self-absorbed, qualitative research can be enlightening, person-centered, and humanistic.

  13. Optimizing Research Payoff.

    PubMed

    Miller, Jeff; Ulrich, Rolf

    2016-09-01

    In this article, we present a model for determining how total research payoff depends on researchers' choices of sample sizes, α levels, and other parameters of the research process. The model can be used to quantify various trade-offs inherent in the research process and thus to balance competing goals, such as (a) maximizing both the number of studies carried out and also the statistical power of each study, (b) minimizing the rates of both false positive and false negative findings, and (c) maximizing both replicability and research efficiency. Given certain necessary information about a research area, the model can be used to determine the optimal values of sample size, statistical power, rate of false positives, rate of false negatives, and replicability, such that overall research payoff is maximized. More specifically, the model shows how the optimal values of these quantities depend upon the size and frequency of true effects within the area, as well as the individual payoffs associated with particular study outcomes. The model is particularly relevant within current discussions of how to optimize the productivity of scientific research, because it shows which aspects of a research area must be considered and how these aspects combine to determine total research payoff.
