This work discusses a novel strategy for inverse planning in low dose rate brachytherapy. It applies the idea of compressed sensing to the problem of inverse treatment planning and a new solver for this formulation is developed. An inverse planning algorithm was developed incorporating brachytherapy dose calculation methods as recommended by AAPM TG-43. For optimization of the functional a new variant of a matching pursuit type solver is presented. The results are compared with current state-of-the-art inverse treatment planning algorithms by means of real prostate cancer patient data. The novel strategy outperforms the best state-of-the-art methods in speed, while achieving comparable quality. It is able to find solutions with comparable values for the objective function and it achieves these results within a few microseconds, being up to 542 times faster than competing state-of-the-art strategies, allowing real-time treatment planning. The sparse solution of inverse brachytherapy planning achieved with methods from compressed sensing is a new paradigm for optimization in medical physics. Through the sparsity of required needles and seeds identified by this method, the cost of intervention may be reduced.

2009-01-01

Optimal design problem are widely known by their multiple performance measures that are often competing with each other. In this paper, an optimal multiproduct batch chemical plant design is presented. The design is firstly formulated as a multiobjective optimization problem, to be solved using the well suited non dominating sorting genetic algorithm (NSGA-II). The NSGA-II have capability to achieve fine tuning of variables in determining a set of non dominating solutions distributed along the Pareto front in a single run of the algorithm. The NSGA-II ability to identify a set of optimal solutions provides the decision-maker DM with a complete picture of the optimal solution space to gain better and appropriate choices. Then an outranking with PROMETHEE II helps the decision-maker to finalize the selection of a best compromise. The effectiveness of NSGA-II method with multiojective optimization problem is illustrated through two carefully referenced examples. PMID:19543537

Replication-competent murine leukemia virus (MLV) vectors can be engineered to achieve high efficiency gene transfer to solid tumors in vivo and tumor-restricted replication, however their safety can be further enhanced by redirecting tropism of the virus envelope. We have therefore tested the targeting capability and replicative stability of ecotropic and amphotropic replication-competent retrovirus (RCR) vectors containing two tandem repeats from the immunoglobulin G-binding domain of Staphylococcal protein A inserted into the proline-rich "hinge" region of the envelope, which enables modular use of antibodies of various specificities for vector targeting. The modified envelopes were efficiently expressed and incorporated into virions, were capable of capturing monoclonal anti-HER2 antibodies, and mediated efficient binding of the virus-antibody complex to HER2-positive target cells. While infectivity was markedly reduced by pseudotyping with targeted envelopes alone, coexpression of wild-type envelope rescued efficient cellular entry. Both ecotropic and amphotropic RCR vector/anti-HER2 antibody complexes achieved significant enhancement of transduction on murine target cells overexpressing HER2, which could be competed by preincubation with excess free antibodies. Interestingly, HER2-expressing human breast cancer cells did not show enhancement of transduction despite efficient antibody-mediated cell surface binding, suggesting that target cell-specific parameters markedly affect the efficiency of post-binding entry processes. Serial replication of targeted vectors resulted in selection of Z domain deletion variants, but reduction of the overall size of the vector genome enhanced its stability. Application of antibody-mediated targeting to the initial localization of replication-competent virus vectors to tumor sites will thus require optimized target selection and vector design.

2016-06-01

This paper is concerned with the fundamental and intrinsic links between early receptive and expressive oral language competence on the one hand and the transition to literacy in the early school years and achievement of academic (and life) success on the other. Consequently, it also concerns the professional knowledge base of two key disciplines whose work is central to children's early language and literacy success: teachers and speech-language pathologists (SLPs). Oral language competence underpins the transition to literacy, which in turn underpins academic achievement. Academic achievement is significant in its own right, conferring opportunities for further education and training post-secondary school, contributing to psychological health and mitigating some of the mental health risks and adversities that can be associated with adolescence and early adulthood. The central thesis is that the linguistic basis of the transition to literacy makes early reading success core business for SLPs. Further, SLPs need a firm grasp of the political and ideological factors that have exerted historical and continuing influence on reading instruction in western nations such as Australia, the US and the UK. This will facilitate the establishment of meaningful working relationships with teaching colleagues, to achieve optimal education outcomes for all children.

To identify if there is a relationship between perceived health competence and burden of care of informal caregivers of family members with Alzheimer's disease and related dementia (ADRD). Informal caregivers 18 years and older who received services from the Alzheimer's Resource of Alaska were invited to complete a survey. Findings indicate that there was a negative correlation between perceived health competence and burden of care (N = 64, r = -.54, p < .001). Additionally, there was a negative correlation within the three subscales of the Modified Montgomery-Borgatta Caregiver Burden Scale: objective burden (r = -.65, p = < .001), stress burden (r = -.41, p = .001), and relationship burden (r = -.29, p = .021, p = .001). Based on the findings of an association between increased caregiver burden and the perception of decreased health competence, nurse practitioners (NPs) can play an important role in assessing caregiver burden. The results of this study enlighten NPs about informal caregiver burden and will help guide discussions and assessments during routine healthcare visits with the goal of achieving optimal health for informal caregivers. ©2016 American Association of Nurse Practitioners.

Structural Optimization of a Force Balance Using a Computational Experiment Design

NASA Technical Reports Server (NTRS)

Parker, P. A.; DeLoach, R.

2002-01-01

This paper proposes a new approach to force balance structural optimization featuring a computational experiment design. Currently, this multi-dimensional design process requires the designer to perform a simplification by executing parameter studies on a small subset of design variables. This one-factor-at-a-time approach varies a single variable while holding all others at a constant level. Consequently, subtle interactions among the design variables, which can be exploited to achieve the design objectives, are undetected. The proposed method combines Modern Design of Experiments techniques to direct the exploration of the multi-dimensional design space, and a finite element analysis code to generate the experimental data. To efficiently search for an optimum combination of design variables and minimize the computational resources, a sequential design strategy was employed. Experimental results from the optimization of a non-traditional force balance measurement section are presented. An approach to overcome the unique problems associated with the simultaneous optimization of multiple response criteria is described. A quantitative single-point design procedure that reflects the designer's subjective impression of the relative importance of various design objectives, and a graphical multi-response optimization procedure that provides further insights into available tradeoffs among competing design objectives are illustrated. The proposed method enhances the intuition and experience of the designer by providing new perspectives on the relationships between the design variables and the competing design objectives providing a systematic foundation for advancements in structural design.

New algorithms for optimal reduction of technical risks

Todinov, M. T.

2013-06-01

The article features exact algorithms for reduction of technical risk by (1) optimal allocation of resources in the case where the total potential loss from several sources of risk is a sum of the potential losses from the individual sources; (2) optimal allocation of resources to achieve a maximum reduction of system failure; and (3) making an optimal choice among competing risky prospects. The article demonstrates that the number of activities in a risky prospect is a key consideration in selecting the risky prospect. As a result, the maximum expected profit criterion, widely used for making risk decisions, is fundamentally flawed, because it does not consider the impact of the number of risk-reward activities in the risky prospects. A popular view, that if a single risk-reward bet with positive expected profit is unacceptable then a sequence of such identical risk-reward bets is also unacceptable, has been analysed and proved incorrect.

Sport ability beliefs, 2 x 2 achievement goals, and intrinsic motivation: the moderating role of perceived competence in sport and exercise.

We examined whether perceived competence moderated the relationships between implicit theories, 2 x 2 achievement goals, and intrinsic motivation for sports and physical activity. We placed 309 university students into high and moderate perceived competence groups. When perceived competence was high, entity beliefs did not predict the performance-avoidance goal; yet when perceived competence was moderately low, entity beliefs did predict this goal. The mastery-avoidance goal had no relationship with intrinsic motivation when perceived competence was high, but had a significant negative relationship when perceived competence was moderately low. Our findings highlight the importance of reexamining the role of perceived competence when studying implicit beliefs and the 2 x 2 achievement goals.

Stochastic injection-strategy optimization for the preliminary assessment of candidate geological storage sites

Cody, Brent M.; Baù, Domenico; González-Nicolás, Ana

2015-09-01

Geological carbon sequestration (GCS) has been identified as having the potential to reduce increasing atmospheric concentrations of carbon dioxide (CO2). However, a global impact will only be achieved if GCS is cost-effectively and safely implemented on a massive scale. This work presents a computationally efficient methodology for identifying optimal injection strategies at candidate GCS sites having uncertainty associated with caprock permeability, effective compressibility, and aquifer permeability. A multi-objective evolutionary optimization algorithm is used to heuristically determine non-dominated solutions between the following two competing objectives: (1) maximize mass of CO2 sequestered and (2) minimize project cost. A semi-analytical algorithm is used to estimate CO2 leakage mass rather than a numerical model, enabling the study of GCS sites having vastly different domain characteristics. The stochastic optimization framework presented herein is applied to a feasibility study of GCS in a brine aquifer in the Michigan Basin (MB), USA. Eight optimization test cases are performed to investigate the impact of decision-maker (DM) preferences on Pareto-optimal objective-function values and carbon-injection strategies. This analysis shows that the feasibility of GCS at the MB test site is highly dependent upon the DM's risk-adversity preference and degree of uncertainty associated with caprock integrity. Finally, large gains in computational efficiency achieved using parallel processing and archiving are discussed.

To develop a decisional tool to identify the most cost effective process flowsheets for allogeneic cell therapies across a range of production scales. A bioprocess economics and optimization tool was built to assess competing cell expansion and downstream processing (DSP) technologies. Tangential flow filtration was generally more cost-effective for the lower cells/lot achieved in planar technologies and fluidized bed centrifugation became the only feasible option for handling large bioreactor outputs. DSP bottlenecks were observed at large commercial lot sizes requiring multiple large bioreactors. The DSP contribution to the cost of goods/dose ranged between 20-55%, and 50-80% for planar and bioreactor flowsheets, respectively. This analysis can facilitate early decision-making during process development.

Lesson Study for Learning Community is one of lecturer profession building system through collaborative and continuous learning study based on the principles of openness, collegiality, and mutual learning to build learning community in order to form professional learning community. To achieve the above, we need a strategy and learning method with specific subscription technique. This paper provides a description of how the quality of learning in the field of science can be improved by implementing strategies and methods accordingly, namely by applying lesson study for learning community optimally. Initially this research was focused on the study of instructional techniques. Learning method used is learning model Contextual teaching and Learning (CTL) and model of Problem Based Learning (PBL). The results showed that there was a significant increase in competence, attitudes, and psychomotor in the four study programs that were modelled. Therefore, it can be concluded that the implementation of learning strategies in Lesson study for Learning Community is needed to be used to improve the competence, attitude and psychomotor of science students.

Children's number competencies over 6 time points, from the beginning of kindergarten to the middle of 1st grade, were examined in relation to their mathematics achievement over 5 later time points, from the end of 1st grade to the end of 3rd grade. The relation between early number competence and mathematics achievement was strong and significant throughout the study period. A sequential process growth curve model showed that kindergarten number competence predicted rate of growth in mathematics achievement between 1st and 3rd grades as well as achievement level through 3rd grade. Further, rate of growth in early number competence predicted mathematics performance level in 3rd grade. Although low-income children performed more poorly than their middle-income counterparts in mathematics achievement and progressed at a slower rate, their performance and growth were mediated through relatively weak kindergarten number competence. Similarly, the better performance and faster growth of children who entered kindergarten at an older age were explained by kindergarten number competence. The findings show the importance of early number competence for setting children's learning trajectories in elementary school mathematics. Copyright 2009 APA, all rights reserved

Matching achievement contexts with implicit theories to maximize motivation after failure: a congruence model.

PubMed

El-Alayli, Amani

2006-12-01

Previous research has shown that matching person variables with achievement contexts can produce the best motivational outcomes. The current study examines whether this is also true when matching entity and incremental beliefs with the appropriate motivational climate. Participants were led to believe that a personal attribute was fixed (entity belief) or malleable (incremental belief). After thinking that they failed a test that assessed the attribute, participants performed a second (related) task in a context that facilitated the pursuit of either performance or learning goals. Participants were expected to exhibit greater effort on the second task in the congruent conditions (entity belief plus performance goal climate and incremental belief plus learning goal climate) than in the incongruent conditions. These results were obtained, but only for participants who either valued competence on the attribute or had high achievement motivation. Results are discussed in terms of developing strategies for optimizing motivation in achievement settings.

Early numerical competencies (ENC) (counting, number relations, and basic arithmetic operations) have a central position in the initial learning of mathematics, and their assessment is useful for predicting later mathematics achievement. Using a regression model, this study aims to analyze the correlational and predictive evidence between ENC and mathematics achievement in first grade Portuguese children ( n = 123). The children's ENC were examined at the point of school entry. Three criterion groups (low, moderate, and high ENC) were formed based on the results of the early numerical brief screener and mathematics achievement measured at the end of first grade. The following hypotheses were tested: children who started first grade with low numerical competencies remained low mathematics achievement at the end of first grade; and children who started with high numerical competencies, finished the first grade with high mathematics achievement. The results showed that ENC contributed to a significant amount of explained variance in mathematics achievement at the end of the first grade. Children with low numerical competencies performed lower than children with moderate and high numerical competencies. Findings suggest that ENC are meaningful for predicting first-grade mathematics difficulties.

Which Preschool Mathematics Competencies Are Most Predictive of Fifth Grade Achievement?

PubMed

Nguyen, Tutrang; Watts, Tyler W; Duncan, Greg J; Clements, Douglas H; Sarama, Julie S; Wolfe, Christopher; Spitler, Mary Elaine

In an effort to promote best practices regarding mathematics teaching and learning at the preschool level, national advisory panels and organizations have emphasized the importance of children's emergent counting and related competencies, such as the ability to verbally count, maintain one-to-one correspondence, count with cardinality, subitize, and count forward or backward from a given number. However, little research has investigated whether the kind of mathematical knowledge promoted by the various standards documents actually predict later mathematics achievement. The present study uses longitudinal data from a primarily low-income and minority sample of children to examine the extent to which preschool mathematical competencies, specifically basic and advanced counting, predict fifth grade mathematics achievement. Using regression analyses, we find early numeracy abilities to be the strongest predictors of later mathematics achievement, with advanced counting competencies more predictive than basic counting competencies. Our results highlight the significance of preschool mathematics knowledge for future academic achievement.

The future role of biomass-derived chemicals relies on the formation of diverse functional monomers in high yields from carbohydrates. Recently, it has become clear that a series of α-hydroxy acids, esters, and lactones can be formed from carbohydrates in alcohol and water solvents using tin-containing catalysts such as Sn-Beta. These compounds are potential building blocks for polyesters bearing additional olefin and alcohol functionalities. An NMR approach was used to identify, quantify, and optimize the formation of these building blocks in the Sn-Beta-catalyzed transformation of abundant carbohydrates. Record yields of the target molecules can be achieved by obstructing competing reactions through solvent selection. © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

Early number competence, grounded in number-specific and domain-general cognitive abilities, is theorized to lay the foundation for later math achievement. Few longitudinal studies have tested a comprehensive model for early math development. Using structural equation modeling and mediation analyses, the present work examined the influence of kindergarteners' nonverbal number sense and domain-general abilities (i.e., working memory, fluid intelligence, and receptive vocabulary) and their early number competence (i.e., symbolic number skills) on first grade math achievement (i.e., arithmetic, shape and space skills, and number line estimation) assessed 1 year later. Latent regression models revealed that nonverbal number sense and working memory are central building blocks for developing early number competence in kindergarten and that early number competence is key for first grade math achievement. After controlling for early number competence, fluid intelligence significantly predicted arithmetic and number line estimation while receptive vocabulary significantly predicted shape and space skills. In sum we suggest that early math achievement draws on different constellations of number-specific and domain-general mechanisms.

Sampling with poling-based flux balance analysis: optimal versus sub-optimal flux space analysis of Actinobacillus succinogenes.

PubMed

Binns, Michael; de Atauri, Pedro; Vlysidis, Anestis; Cascante, Marta; Theodoropoulos, Constantinos

2015-02-18

Flux balance analysis is traditionally implemented to identify the maximum theoretical flux for some specified reaction and a single distribution of flux values for all the reactions present which achieve this maximum value. However it is well known that the uncertainty in reaction networks due to branches, cycles and experimental errors results in a large number of combinations of internal reaction fluxes which can achieve the same optimal flux value. In this work, we have modified the applied linear objective of flux balance analysis to include a poling penalty function, which pushes each new set of reaction fluxes away from previous solutions generated. Repeated poling-based flux balance analysis generates a sample of different solutions (a characteristic set), which represents all the possible functionality of the reaction network. Compared to existing sampling methods, for the purpose of generating a relatively "small" characteristic set, our new method is shown to obtain a higher coverage than competing methods under most conditions. The influence of the linear objective function on the sampling (the linear bias) constrains optimisation results to a subspace of optimal solutions all producing the same maximal fluxes. Visualisation of reaction fluxes plotted against each other in 2 dimensions with and without the linear bias indicates the existence of correlations between fluxes. This method of sampling is applied to the organism Actinobacillus succinogenes for the production of succinic acid from glycerol. A new method of sampling for the generation of different flux distributions (sets of individual fluxes satisfying constraints on the steady-state mass balances of intermediates) has been developed using a relatively simple modification of flux balance analysis to include a poling penalty function inside the resulting optimisation objective function. This new methodology can achieve a high coverage of the possible flux space and can be used with and without linear bias to show optimal versus sub-optimal solution spaces. Basic analysis of the Actinobacillus succinogenes system using sampling shows that in order to achieve the maximal succinic acid production CO₂ must be taken into the system. Solutions involving release of CO₂ all give sub-optimal succinic acid production.

This study analyzes the relationship between emotion understanding and school achievement in children of primary school, considering age, gender, fluid intelligence, mother’s educational level and social competence. In this study participated 406 children of primary school. The instruments used were the Test of Emotion Comprehension, Colored Progressive Matrices of Raven, Socially Action and Interpersonal Problem Solving Scale. The structural equation model showed the relationship between the emotion understanding and school performance depends on a mediator variable that in the context of the study was designated social competence. Age appear as an explanatory factor of the differences found, the mother’s educational level only predicts significantly social emotional competence, fluid intelligence is a predictor of emotion understanding, school achievement and social emotional competence. Regarding the influence of sex, emotional understanding does not emerge as a significant predictor of social emotional competence in girls or boys. Multiple relationships between the various factors associated with school achievement and social emotional competence are discussed as well as their implications in promoting child development and school success.

One hundred children (44 boys) participated in a 3-year longitudinal study of the development of basic quantitative competencies and the relation between these competencies and later mathematics and reading achievement. The children's preliteracy knowledge, intelligence, executive functions, and parental educational background were also assessed. The quantitative tasks assessed a broad range of symbolic and nonsymbolic knowledge and were administered four times across 2 years of preschool. Mathematics achievement was assessed at the end of each of 2 years of preschool, and mathematics and word reading achievement were assessed at the end of kindergarten. Our goals were to determine how domain-general abilities contribute to growth in children's quantitative knowledge and to determine how domain-general and domain-specific abilities contribute to children's preschool mathematics achievement and kindergarten mathematics and reading achievement. We first identified four core quantitative competencies (e.g., knowledge of the cardinal value of number words) that predict later mathematics achievement. The domain-general abilities were then used to predict growth in these competencies across 2 years of preschool, and the combination of domain-general abilities, preliteracy skills, and core quantitative competencies were used to predict mathematics achievement across preschool and mathematics and word reading achievement at the end of kindergarten. Both intelligence and executive functions predicted growth in the four quantitative competencies, especially across the first year of preschool. A combination of domain-general and domain-specific competencies predicted preschoolers' mathematics achievement, with a trend for domain-specific skills to be more strongly related to achievement at the beginning of preschool than at the end of preschool. Preschool preliteracy skills, sensitivity to the relative quantities of collections of objects, and cardinal knowledge predicted reading and mathematics achievement at the end of kindergarten. Preliteracy skills were more strongly related to word reading, whereas sensitivity to relative quantity was more strongly related to mathematics achievement. The overall results indicate that a combination of domain-general and domain-specific abilities contribute to development of children's early mathematics and reading achievement. PMID:27252675

One hundred children (44 boys) participated in a 3-year longitudinal study of the development of basic quantitative competencies and the relation between these competencies and later mathematics and reading achievement. The children's preliteracy knowledge, intelligence, executive functions, and parental educational background were also assessed. The quantitative tasks assessed a broad range of symbolic and nonsymbolic knowledge and were administered four times across 2 years of preschool. Mathematics achievement was assessed at the end of each of 2 years of preschool, and mathematics and word reading achievement were assessed at the end of kindergarten. Our goals were to determine how domain-general abilities contribute to growth in children's quantitative knowledge and to determine how domain-general and domain-specific abilities contribute to children's preschool mathematics achievement and kindergarten mathematics and reading achievement.

Conroy, David E; Pincus, Aaron L

2011-08-01

Two studies evaluated relations between different forms of achievement motivation and transactional interpersonal impact messages during a dyadic puzzle-solving task. In Study 1,400 college students received no formal competence feedback during the task. In Study 2, competence feedback was manipulated for 600 college students and used to create high-, low-, and mixed-status dyads. Expectancies of success had robust actor and partner effects on submission in both studies. Competence valuation was linked with communal partner effects in Study 1 and a generalized interpersonal sensitivity in Study 2. When competence was ambiguous, approach and avoidance achievement motives exhibited affectively driven actor and partner effects consistent with their roots in pride and shame, respectively; however, when competence was established formally, motives had more cognitively driven effects on person perception and behavior (e.g., rejection sensitivity). Collectively, these findings highlight the importance of the achievement motivation system for organizing interpersonal impact messages during competence pursuits. © 2011 The Authors.

In an effort to promote best practices regarding mathematics teaching and learning at the preschool level, national advisory panels and organizations have emphasized the importance of children’s emergent counting and related competencies, such as the ability to verbally count, maintain one-to-one correspondence, count with cardinality, subitize, and count forward or backward from a given number. However, little research has investigated whether the kind of mathematical knowledge promoted by the various standards documents actually predict later mathematics achievement. The present study uses longitudinal data from a primarily low-income and minority sample of children to examine the extent to which preschool mathematical competencies, specifically basic and advanced counting, predict fifth grade mathematics achievement. Using regression analyses, we find early numeracy abilities to be the strongest predictors of later mathematics achievement, with advanced counting competencies more predictive than basic counting competencies. Our results highlight the significance of preschool mathematics knowledge for future academic achievement. PMID:27057084

The UNE-EN-ISO 15189:2007 standard defines the requirements for quality and competence that must be met by medical laboratories. These laboratories should use this international standard to develop their own quality management systems and to evaluate their own competencies; in turn, this standard will be used by accreditation bodies to confirm or recognize the laboratories' competence. In clinical microbiology laboratories, application of the standard implies the implementation of the technical and specific management requirements that must be met to achieve optimal quality when carrying out microbiological tests. In Spain, accreditation is granted by the Spanish Accreditation Body (Entidad Nacional de Acreditación). This review aims to discuss the practical application of the standard's technical requirements in mycobacterial laboratory. Firstly, we define the scope of accreditation. Secondly, we specify how the items of the standard on personnel management, control of equipment, environmental facilities, method validation, internal controls and customer satisfaction surveys were developed and implemented in our laboratory.

Vanderplaats, G. N.; Chen, Xiang; Zhang, Ning-Tian

1988-01-01

The use of formal numerical optimization methods for the design of gears is investigated. To achieve this, computer codes were developed for the analysis of spur gears and spiral bevel gears. These codes calculate the life, dynamic load, bending strength, surface durability, gear weight and size, and various geometric parameters. It is necessary to calculate all such important responses because they all represent competing requirements in the design process. The codes developed here were written in subroutine form and coupled to the COPES/ADS general purpose optimization program. This code allows the user to define the optimization problem at the time of program execution. Typical design variables include face width, number of teeth and diametral pitch. The user is free to choose any calculated response as the design objective to minimize or maximize and may impose lower and upper bounds on any calculated responses. Typical examples include life maximization with limits on dynamic load, stress, weight, etc. or minimization of weight subject to limits on life, dynamic load, etc. The research codes were written in modular form for easy expansion and so that they could be combined to create a multiple reduction optimization capability in future.

An important goal of nursing education is helping students achieve core competencies efficiently. One proposed way of improving nursing education is team-based learning (TBL). The aim of this study was to assess the comparative effectiveness of TBL and lecture-style classes in terms of teaching core competencies in nursing education, which include clinical competence skills, problem-solving ability, communication competencies, critical thinking ability, and self-leadership. This quasi-experimental study enrolled 183 students as participants, with 95 and 88 in the experimental and control groups, respectively. These two groups attended 6 hours (2 hours weekly for 3 weeks) of TBL and lecture-style classes, respectively. Differences in core competencies between the two groups were compared before and after the intervention. The experimental group achieved significantly higher scores for clinical competence skills, communication competence, critical thinking ability, and self-leadership at posttest than at pretest, whereas the control group achieved significantly higher scores for clinical competence skills and critical thinking ability at posttest than at pretest. After the intervention, the experimental group had significantly better clinical competence skills, communication competence, and self-leadership than the control group. TBL is an effective approach method to teaching core competencies in nursing education.

To use the cumulative sum analysis score (CUSUM) to construct objectively the learning curve of phacoemulsification competency. Three second-year residents and an experienced consultant were monitored for a series of 70 phacoemulsification cases each and had their series analysed by CUSUM regarding posterior capsule rupture (PCR) and best-corrected visual acuity. The acceptable rate for PCR was <5% (lower limit h) and the unacceptable rate was >10% (upper limit h). The acceptable rate for best-corrected visual acuity worse than 20/40 was <10% (lower limit h) and the unacceptable rate was >20% (upper limit h). The area between lower limit h and upper limit h is called the decision interval. There was no statistically significant difference in the mean age, sex or cataract grades between groups. The first trainee achieved PCR CUSUM competency at his 22 nd case. His best-corrected visual acuity CUSUM was in the decision interval from his third case and stayed there until the end, never reaching competency. The second trainee achieved PCR CUSUM competency at his 39 th case. He could reach best-corrected visual acuity CUSUM competency at his 22 nd case. The third trainee achieved PCR CUSUM competency at his 41 st case. He reached best-corrected visual acuity CUSUM competency at his 14 th case. The learning curve of competency in phacoemulsification is constructed by CUSUM and in average took 38 cases for each trainee to achieve it.

Autonomy, Competence, and Intrinsic Motivation in Science Education: A Self- Determination Theory Perspective

NASA Astrophysics Data System (ADS)

Painter, Jason

The purpose of this study was to examine a proposed motivational model of science achievement based on self-determination theory. The study relied on U.S. eighth-grade science data from the 2007 Third International Mathematics and Science Study to examine a structural model that hypothesized how perceived autonomy support, perceived competence in science, intrinsic motivation, and science achievement related to each other. Mother's education and student gender were used as controls. Findings showed that the hypothesized model provided a good fit to the data. The strongest direct effect on science achievement was students' perceived competence in science. Student intrinsic motivation was shown to have a surprisingly negative effect on science achievement. Autonomy support had positive direct effects on students' perceived competence in science and intrinsic motivation and had indirect positive effects to science achievement. Results and implications for science education are discussed.

The primary goal of a residency program is to prepare trainees for unsupervised care. Duty hour restrictions imposed throughout the prior decade require that residents work significantly fewer hours. Moreover, various stakeholders (e.g. the hospital, mentors, other residents, educators, and patients) require them to prioritize very different activities, often conflicting with their learning goals. Surgical residents' learning goals include providing continuity throughout a patient's pre-, peri-, and post-operative care as well as achieving sufficient surgical experience levels in various procedure types and participating in various formal educational activities, among other things. To complicate matters, senior residents often compete with other residents for surgical experience. This paper features experiments using an optimization model and a real dataset. The experiments test the viability of achieving the above goals at a major academic center using existing models of delivering medical education and training to surgical residents. It develops a detailed multi-objective, two-stage stochastic optimization model with anticipatory capabilities solved over a rolling time horizon. A novel feature of the models is the incorporation of learning curve theory in the objection function. Using a deterministic version of the model, we identify bounds on the achievement of learning goals under existing training paradigms. The computational results highlight the structural problems in the current surgical resident educational system. These results further corroborate earlier findings and suggest an educational system redesign is necessary for surgical medical residents.

Vaccines are arguably the most important means of pandemic influenza mitigation. However, as during the 2009 H1N1 pandemic, mass immunization with an effective vaccine may not begin until a pandemic is well underway. In the U.S., state-level public health agencies are responsible for quickly and fairly allocating vaccines as they become available to populations prioritized to receive vaccines. Allocation decisions can be ethically and logistically complex, given several vaccine types in limited and uncertain supply and given competing priority groups with distinct risk profiles and vaccine acceptabilities. We introduce a model for optimizing statewide allocation of multiple vaccine types to multiple priority groups, maximizing equal access. We assume a large fraction of available vaccines are distributed to healthcare providers based on their requests, and then optimize county-level allocation of the remaining doses to achieve equity. We have applied the model to the state of Texas, and incorporated it in a Web-based decision-support tool for the Texas Department of State Health Services (DSHS). Based on vaccine quantities delivered to registered healthcare providers in response to their requests during the 2009 H1N1 pandemic, we find that a relatively small cache of discretionary doses (DSHS reserved 6.8% in 2009) suffices to achieve equity across all counties in Texas.

The relation between children's accuracy estimates of their physical competence and achievement-related characteristics.

The relationship between perceptions of competence and control, achievement, and motivated behavior in youth sport has been a topic of considerable interest. The purpose of this study was to examine whether children who are under-, accurate, or overestimators of their physical competence differ in their achievement characteristics. Children (N = 133), 8 to 13 years of age, who were attending a summer sport program, completed a series of questionnaires designed to assess perceptions of competence and control, motivational orientation, and competitive trait anxiety. Measures of physical competence were obtained by teachers' ratings that paralleled the children's measure of perceived competence. Perceived competence and teachers' ratings were standardized by grade level, and an accuracy score was computed from the difference between these scores. Children were then categorized as underestimators, accurate raters, or overestimators according to upper and lower quartiles of this distribution. A 2 x 2 x 3 (age level by gender by accuracy) MANCOVA revealed a significant gender by accuracy interaction. Underestimating girls were lower in challenge motivation, higher in trait anxiety, and more external in their control perceptions than accurate or overestimators. Underestimating boys were higher in perceived unknown control than accurate and overestimating boys. It was concluded that children who seriously underestimate their perceived competence may be likely candidates for discontinuation of sport activities or low levels of physical achievement.

To investigate the associations of self-perceived competence in diabetes management and autonomy support from healthcare providers with diabetes distress in adults with Type 1 diabetes mellitus that is not optimally controlled [HbA(1c) ≥ 64 mmol/mol (8.0%)]. This cross-sectional study comprised blood sampling and three self-report questionnaires, the Problem Areas in Diabetes scale, the Perceived Competence in Diabetes Scale and a measure of autonomy support by healthcare providers, the Health Care Climate Questionnaire. We fitted blockwise linear regression models to assess the associations between Problem Areas in Diabetes score and the variables of interest (autonomy support and perceived diabetes competence), controlling for clinical and sociodemographic variables. Of the study sample [n = 178; mean age 36.7 (±10.7) years], 31.5% had long-term complications and 43.2% reported elevated (≥40) Problem Areas in Diabetes scores. A significant negative association was found between autonomy support and Problem Areas in Diabetes score (B = -3.61, P = 0.001), indicating that lower autonomy support was associated with greater diabetes distress. When perceived competence was controlled, it mediated the association of autonomy support with diabetes distress, reducing it to non-significance. There was a significant negative association between perceived competence and Problem Areas in Diabetes score (B = -8.89, P < 0.001), indicating that lower perceived competence was associated with greater perceived distress. There was an indirect (fully mediated) relationship between autonomy support and diabetes distress; autonomy support was associated with increased perceived competence, which, in turn, was associated with reduced distress. Healthcare providers' communication styles enhancing perceived competence through autonomy support may contribute to effective treatment for people with Type 1 diabetes and suboptimum glycaemic control. © 2015 The Authors.

2010-08-01

The primary purpose of this longitudinal study was to examine, in a sample of Chinese children (initial M age = 8 years, N = 1,140), contributions of aggression to the development of social competence and academic achievement. Five waves of panel data on aggression and social and school performance were collected from peer evaluations, teacher ratings, and school records in Grades 2 to 5. Structural equation modeling revealed that aggression had unique effects on later social competence and academic achievement after their stabilities were controlled, particularly in the junior grades. Aggression also had significant indirect effects on social and academic outcomes through multiple pathways. Social competence and academic achievement contributed to the development of each other, but not aggression. The results indicate cascade effects of aggression in Chinese children from a developmental perspective.

2008-01-01

In spite of the complexity of human motor behavior, difficulties in mathematical modeling have restricted to rather simple movements attempts to identify the motor planning criterion used by the central nervous system. This paper presents a novel-simulation technique able to predict the "desired trajectory" corresponding to a wide range of kinematic and kinetic optimality criteria for tasks involving many degrees of freedom and the coordination between goal achievement and balance maintenance. Employment of proper time discretization, inverse dynamic methods and constrained optimization technique are combined. The application of this simulator to a planar whole body pointing movement shows its effectiveness in managing system nonlinearities and instability as well as in ensuring the anatomo-physiological feasibility of predicted motor plans. In addition, the simulator's capability to simultaneously optimize competing movement aspects represents an interesting opportunity for the motor control community, in which the coexistence of several controlled variables has been hypothesized.

2018-03-01

Basic numerical competences are seen as building blocks for later numerical and mathematical achievement. The current study aimed at investigating the structure of early numeracy reflected by different basic numerical competences in kindergarten and its predictive value for mathematical achievement 6 years later using data from large-scale assessment. This allowed analyses based on considerably large sample sizes (N > 1700). A confirmatory factor analysis indicated that a model differentiating five basic numerical competences at the end of kindergarten fitted the data better than a one-factor model of early numeracy representing a comprehensive number sense. In addition, these basic numerical competences were observed to reliably predict performance in a curricular mathematics test in Grade 6 even after controlling for influences of general cognitive ability. Thus, our results indicated a differentiated view on early numeracy considering basic numerical competences in kindergarten reflected in large-scale assessment data. Consideration of different basic numerical competences allows for evaluating their specific predictive value for later mathematical achievement but also mathematical learning difficulties.

2003-06-01

Children's perceived competence and intrinsic motivation are assumed to be very high at the outset of schooling. However, how they change and how they relate to each other and to academic achievement across early schooling years remain open to question. This 3-year longitudinal study was aimed at examining the following questions. Do children's perceived competence and intrinsic motivation about reading and mathematics change across the first 3 years of schooling? Do their perceived competence and intrinsic motivation differ according to academic domains? Do their perceived competence and intrinsic motivation relate to their academic achievement in each academic domain? A total of 115 elementary schoolchildren (63 boys and 52 girls) were examined in first grade (mean age = 84,5 months, SD =.67) and for the next 2 years. Children responded to questionnaires about their perceived competence and intrinsic motivation in reading and mathematics. Year-end grades in these two subjects were used as a measure of performance. Changes in perceived competence and intrinsic motivation, and between-year intercorrelations, were observed to differ according to academic domains and gender. Intrinsic motivation did not make a significant contribution to academic achievement at either school grade or in any academic domain, whereas perceived competence was significantly related to achievement at each school grade in both reading and mathematics. Differences between boys and girls observed in this study were not linked to a specific domain and cannot be attributed to gender-role stereotypes. Girls appeared to be more precocious in differentiating their competence and intrinsic motivation according to academic domain, as well as in being able to process and integrate information about their ability from past performances in a domain to judge their competence in the same domain.

Enjoying mathematics or feeling competent in mathematics? Reciprocal effects on mathematics achievement and perceived math effort expenditure.

The multidimensionality of the academic self-concept in terms of domain specificity has been well established in previous studies, whereas its multidimensionality in terms of motivational functions (the so-called affect-competence separation) needs further examination. This study aims at exploring differential effects of enjoyment and competence beliefs on two external validity criteria in the field of mathematics. Data analysed in this study were part of a large-scale longitudinal research project. Following a five-wave design, math enjoyment, math competence beliefs, math achievement, and perceived math effort expenditure measures were repeatedly collected from a cohort of 4,724 pupils in Grades 3-7. Confirmatory factor analysis (CFA) was used to test the internal factor structure of the math self-concept. Additionally, a series of nested models was tested using structural equation modelling to examine longitudinal reciprocal interrelations between math competence beliefs and math enjoyment on the one hand and math achievement and perceived math effort expenditure on the other. Our results showed that CFA models with separate factors for math enjoyment and math competence beliefs fit the data substantially better than models without it. Furthermore, differential relationships between both constructs and the two educational outcomes were observed. Math competence beliefs had positive effects on math achievement and negative effects on perceived math effort expenditure. Math enjoyment had (mild) positive effects on subsequent perceived effort expenditure and math competence beliefs. This study provides further support for the affect-competence separation. Theoretical issues regarding adequate conceptualization and practical consequences for practitioners are discussed. © 2013 The British Psychological Society.

Exploring the impact of phonological awareness, visual-spatial working memory, and preschool quantity-number competencies on mathematics achievement in elementary school: findings from a 3-year longitudinal study.

PubMed

Krajewski, Kristin; Schneider, Wolfgang

2009-08-01

This longitudinal study explored the importance of kindergarten measures of phonological awareness, working memory, and quantity-number competencies (QNC) for predicting mathematical school achievement in third graders (mean age 8 years 8 months). It was found that the impact of phonological awareness and visual-spatial working memory, assessed at 5 years of age, was mediated by early QNC, which predicted math achievement in third grade. Importantly, and confirming our isolated number words hypothesis, phonological awareness had no impact on higher numerical competencies (i.e., when number words needed to be linked with quantities [QNC Level II and above]) but predicted basic numerical competencies (i.e., when number words were isolated from quantities [QNC Level I]), explaining the moderate relationship between early literacy development and the development of mathematical competencies.

To explore international consensus for the validation of clinical competencies for advanced training in Oral Medicine. An electronic survey of clinical competencies was designed. The survey was sent to and completed by identified international stakeholders during a 10-week period. To be validated, an individual competency had to achieve 90% or greater consensus to keep it in its current format. Stakeholders from 31 countries responded. High consensus agreement was achieved with 93 of 101 (92%) competencies exceeding the benchmark for agreement. Only 8 warranted further attention and were reviewed by a focus group. No additional competencies were suggested. This is the first international validated study of clinical competencies for advanced training in Oral Medicine. These validated clinical competencies could provide a model for countries developing an advanced training curriculum for Oral Medicine and also inform review of existing curricula.

The Brazilian undergraduate medical course is six years long. As in other countries, a medical residency is not obligatory to practice as a doctor. In this context, this paper aims to clarify what and when competencies in communication and professionalism should be addressed, shedding light on the role of university, residency and post-residency programmes. Brazilian family physicians with diverse levels of medical training answered a questionnaire designed to seek a consensus on the competencies that should be taught (key competencies) and when students should achieve them during their medical training. The data were analysed using descriptive statistics and correlation tests. A total of seventy-four physicians participated; nearly all participants suggested that the students should achieve communication and professionalism competencies during undergraduate study (twenty out of thirty competencies - 66.7%) or during residency (seven out of thirty competencies - 23.33%). When competencies were analysed in domains, the results were that clinical communication skills and professionalism competencies should be achieved during undergraduate medical education, and interpersonal communication and leadership skills should be reached during postgraduate study. The authors propose that attainment of clinical communication skills and professionalism competencies should be required for undergraduate students. The foundation for Leadership and Interpersonal Abilities should be particularly formed at an undergraduate level and, furthermore, mastered by immersion in the future workplace and medical responsibilities in residency.

Competence with fractions predicts later mathematics achievement, but the co-developmental pattern between fractions knowledge and mathematics achievement is not well understood. We assessed this co-development through examination of the cross-lagged relation between a measure of conceptual knowledge of fractions and mathematics achievement in sixth and seventh grade (n = 212). The cross-lagged effects indicated that performance on the sixth grade fractions concepts measure predicted one year gains in mathematics achievement (β = .14, p<.01), controlling for the central executive component of working memory and intelligence, but sixth grade mathematics achievement did not predict gains on the fractions concepts measure (β = .03, p>.50). In a follow-up assessment, we demonstrated that measures of fluency with computational fractions significantly predicted seventh grade mathematics achievement above and beyond the influence of fluency in computational whole number arithmetic, performance on number fluency and number line tasks, and central executive span and intelligence. Results provide empirical support for the hypothesis that competence with fractions underlies, in part, subsequent gains in mathematics achievement. PMID:22832199

EmptyHeaded: A Relational Engine for Graph Processing

Aberger, Christopher R.; Tu, Susan; Olukotun, Kunle; Ré, Christopher

2016-01-01

There are two types of high-performance graph processing engines: low- and high-level engines. Low-level engines (Galois, PowerGraph, Snap) provide optimized data structures and computation models but require users to write low-level imperative code, hence ensuring that efficiency is the burden of the user. In high-level engines, users write in query languages like datalog (SociaLite) or SQL (Grail). High-level engines are easier to use but are orders of magnitude slower than the low-level graph engines. We present EmptyHeaded, a high-level engine that supports a rich datalog-like query language and achieves performance comparable to that of low-level engines. At the core of EmptyHeaded’s design is a new class of join algorithms that satisfy strong theoretical guarantees but have thus far not achieved performance comparable to that of specialized graph processing engines. To achieve high performance, EmptyHeaded introduces a new join engine architecture, including a novel query optimizer and data layouts that leverage single-instruction multiple data (SIMD) parallelism. With this architecture, EmptyHeaded outperforms high-level approaches by up to three orders of magnitude on graph pattern queries, PageRank, and Single-Source Shortest Paths (SSSP) and is an order of magnitude faster than many low-level baselines. We validate that EmptyHeaded competes with the best-of-breed low-level engine (Galois), achieving comparable performance on PageRank and at most 3× worse performance on SSSP. PMID:28077912

2013-01-01

The SynGenics Optimization System (SynOptSys) software application optimizes a product with respect to multiple, competing criteria using statistical Design of Experiments, Response-Surface Methodology, and the Desirability Optimization Methodology. The user is not required to be skilled in the underlying math; thus, SynOptSys can help designers and product developers overcome the barriers that prevent them from using powerful techniques to develop better pro ducts in a less costly manner. SynOpt-Sys is applicable to the design of any product or process with multiple criteria to meet, and at least two factors that influence achievement of those criteria. The user begins with a selected solution principle or system concept and a set of criteria that needs to be satisfied. The criteria may be expressed in terms of documented desirements or defined responses that the future system needs to achieve. Documented desirements can be imported into SynOptSys or created and documented directly within SynOptSys. Subsequent steps include identifying factors, specifying model order for each response, designing the experiment, running the experiment and gathering the data, analyzing the results, and determining the specifications for the optimized system. The user may also enter textual information as the project progresses. Data is easily edited within SynOptSys, and the software design enables full traceability within any step in the process, and facilitates reporting as needed. SynOptSys is unique in the way responses are defined and the nuances of the goodness associated with changes in response values for each of the responses of interest. The Desirability Optimization Methodology provides the basis of this novel feature. Moreover, this is a complete, guided design and optimization process tool with embedded math that can remain invisible to the user. It is not a standalone statistical program; it is a design and optimization system.

Primary Palliative Care for the General Internist: Integrating Goals of Care Discussions into the Outpatient Setting

Ahia, Chad L.; Blais, Christopher M.

2014-01-01

Background Primary palliative care consists of the palliative care competencies required of all primary care clinicians. Included in these competencies is the ability to assist patients and their families in establishing appropriate goals of care. Goals of care help patients and their families understand the patient's illness and its trajectory and facilitate medical care decisions consistent with the patient's values and goals. General internists and family medicine physicians in primary care are central to getting patients to articulate their goals of care and to have these documented in the medical record. Case Report Here we present the case of a 71-year-old male patient with chronic obstructive pulmonary disorder, congestive heart failure, and newly diagnosed Alzheimer dementia to model pertinent end-of-life care communication and discuss practical tips on how to incorporate it into practice. Conclusion General internists and family medicine practitioners in primary care are central to eliciting patients' goals of care and achieving optimal end-of-life outcomes for their patients.

Recent efforts to improve medical education include adopting a new framework based on 6 broad competencies defined by the Accreditation Council for Graduate Medical Education. In this article, the Alliance for Academic Internal Medicine Education Redesign Task Force II examines the advantages and challenges of a competency-based educational framework for medical residents. Efforts to refine specific competencies by developing detailed milestones are described, and examples of training program initiatives using a competency-based approach are presented. Meeting the challenges of a competency-based framework and supporting these educational innovations require a robust faculty development program. Challenges to competency-based education include teaching and evaluating the competencies related to practice-based learning and improvement and systems-based practice, as well as implementing a flexible time frame to achieve competencies. However, the Alliance for Academic Internal Medicine Education Redesign Task Force II does not favor reducing internal medicine training to less than 36 months as part of competency-based education. Rather, the 36-month time frame should allow for remediation to address deficiencies in achieving competencies and for diverse enrichment experiences in such areas as quality of care and practice improvement for residents who have demonstrated skills in all required competencies.

A Chemical Engineer's Perspective on Health and Disease

2014-01-01

Chemical process systems engineering considers complex supply chains which are coupled networks of dynamically interacting systems. The quest to optimize the supply chain while meeting robustness and flexibility constraints in the face of ever changing environments necessitated the development of theoretical and computational tools for the analysis, synthesis and design of such complex engineered architectures. However, it was realized early on that optimality is a complex characteristic required to achieve proper balance between multiple, often competing, objectives. As we begin to unravel life's intricate complexities, we realize that that living systems share similar structural and dynamic characteristics; hence much can be learned about biological complexity from engineered systems. In this article, we draw analogies between concepts in process systems engineering and conceptual models of health and disease; establish connections between these concepts and physiologic modeling; and describe how these mirror onto the physiological counterparts of engineered systems.

To examine functioning and participation in a diverse U.S. sample of 180 infants at age 17 years. The World Health Organization International Classification of Functioning, Disability and Health model framed functioning and participation domains and contextual factors. Assessment included cognition, executive functioning, academic achievement, personal functioning, community participation, and social involvement. Socioeconomic status, not prematurity, impacted cognitive and academic outcomes. Across neonatal morbidities, male gender and social disadvantage are key determinants of cognitive, academic, and social functioning. Interventions addressing academic and social-behavioral competencies in early school years may potentially optimize long-term preterm outcomes. © 2012, Wiley Periodicals, Inc.

Expectations of clinical teachers and faculty regarding development of the CanMEDS-Family Medicine competencies: Laval developmental benchmarks scale for family medicine residency training.

2014-01-01

The CanMEDS-Family Medicine (CanMEDS-FM) framework defines the expected terminal enabling competencies (EC) for family medicine (FM) residency training in Canada. However, benchmarks throughout the 2-year program are not yet defined. This study aimed to identify expected time frames for achievement of the CanMEDS-FM competencies during FM residency training and create a developmental benchmarks scale for family medicine residency training. This 2011-2012 study followed a Delphi methodology. Selected faculty and clinical teachers identified, via questionnaire, the expected time of EC achievement from beginning of residency to one year in practice (0, 6, 12, […] 36 months). The 15-85th percentile intervals became the expected competency achievement interval. Content validity of the obtained benchmarks was assessed through a second Delphi round. The 1st and 2nd rounds were completed by 33 and 27 respondents, respectively. A developmental benchmarks scale was designed after the 1st round to illustrate expectations regarding achievement of each EC. The 2nd round (content validation) led to minor adjustments (1.9±2.7 months) of intervals for 44 of the 92 competencies, the others remaining unchanged. The Laval Developmental Benchmarks Scale for Family Medicine clarifies expectations regarding achievement of competencies throughout FM training. In a competency-based education system this now allows identification and management of outlying residents, both those excelling and needing remediation. Further research should focus on assessment of the scale reliability after pilot implementation in family medicine clinical teaching units at Laval University, and corroborate the established timeline in other sites.

Parana Basin Structure from Multi-Objective Inversion of Surface Wave and Receiver Function by Competent Genetic Algorithm

An, M.; Assumpcao, M.

2003-12-01

The joint inversion of receiver function and surface wave is an effective way to diminish the influences of the strong tradeoff among parameters and the different sensitivity to the model parameters in their respective inversions, but the inversion problem becomes more complex. Multi-objective problems can be much more complicated than single-objective inversion in the model selection and optimization. If objectives are involved and conflicting, models can be ordered only partially. In this case, Pareto-optimal preference should be used to select solutions. On the other hand, the inversion to get only a few optimal solutions can not deal properly with the strong tradeoff between parameters, the uncertainties in the observation, the geophysical complexities and even the incompetency of the inversion technique. The effective way is to retrieve the geophysical information statistically from many acceptable solutions, which requires more competent global algorithms. Competent genetic algorithms recently proposed are far superior to the conventional genetic algorithm and can solve hard problems quickly, reliably and accurately. In this work we used one of competent genetic algorithms, Bayesian Optimization Algorithm as the main inverse procedure. This algorithm uses Bayesian networks to draw out inherited information and can use Pareto-optimal preference in the inversion. With this algorithm, the lithospheric structure of Paran"› basin is inverted to fit both the observations of inter-station surface wave dispersion and receiver function.

Splash-cup plants accelerate raindrops to disperse seeds.

PubMed

Amador, Guillermo J; Yamada, Yasukuni; McCurley, Matthew; Hu, David L

2013-02-01

The conical flowers of splash-cup plants Chrysosplenium and Mazus catch raindrops opportunistically, exploiting the subsequent splash to disperse their seeds. In this combined experimental and theoretical study, we elucidate their mechanism for maximizing dispersal distance. We fabricate conical plant mimics using three-dimensional printing, and use high-speed video to visualize splash profiles and seed travel distance. Drop impacts that strike the cup off-centre achieve the largest dispersal distances of up to 1 m. Such distances are achieved because splash speeds are three to five times faster than incoming drop speeds, and so faster than the traditionally studied splashes occurring upon horizontal surfaces. This anomalous splash speed is because of the superposition of two components of momentum, one associated with a component of the drop's motion parallel to the splash-cup surface, and the other associated with film spreading induced by impact with the splash-cup. Our model incorporating these effects predicts the observed dispersal distance within 6-18% error. According to our experiments, the optimal cone angle for the splash-cup is 40°, a value consistent with the average of five species of splash-cup plants. This optimal angle arises from the competing effects of velocity amplification and projectile launching angle.

Cognitive Predictors of Achievement Growth in Mathematics: A Five Year Longitudinal Study

Geary, David C.

2011-01-01

The study's goal was to identify the beginning of first grade quantitative competencies that predict mathematics achievement start point and growth through fifth grade. Measures of number, counting, and arithmetic competencies were administered in early first grade and used to predict mathematics achievement through fifth (n = 177), while controlling for intelligence, working memory, and processing speed. Multilevel models revealed intelligence, processing speed, and the central executive component of working memory predicted achievement or achievement growth in mathematics and, as a contrast domain, word reading. The phonological loop was uniquely predictive of word reading and the visuospatial sketch pad of mathematics. Early fluency in processing and manipulating numerical set size and Arabic numerals, accurate use of sophisticated counting procedures for solving addition problems, and accuracy in making placements on a mathematical number line were uniquely predictive of mathematics achievement. Use of memory-based processes to solve addition problems predicted mathematics and reading achievement but in different ways. The results identify the early quantitative competencies that uniquely contribute to mathematics learning. PMID:21942667

Achievement goals as mediators of the relationship between competence beliefs and test anxiety.

PubMed

Putwain, David W; Symes, Wendy

2012-06-01

Previous work suggests that the expectation of failure is related to higher test anxiety and achievement goals grounded in a fear of failure. To test the hypothesis, based on the work of Elliot and Pekrun (2007), that the relationship between perceived competence and test anxiety is mediated by achievement goal orientations. Self-report data were collected from 275 students in post-compulsory education following courses in A Level Psychology. Competence beliefs were inversely related to the worry and tension components of test anxiety, both directly and indirectly through a performance-avoidance goal orientation. A mastery-avoidance goal orientation offered an indirect route from competence beliefs to worry only. These findings provide partial support for Elliot and Pekrun's (2007) model. Although significant mediating effects were found for mastery-avoidance and performance-avoidance goals, they were small and there may be other mechanisms to account for the relations between competence beliefs and test anxiety. ©2011 The British Psychological Society.

The goal of this study was to assess achievement goal dominance, self-determined situational motivation and competence in high-level swimmers before and after three training sessions set at different working intensities (medium, sub-maximal and maximal). Nineteen athletes (males, n=9, 18.00±2.32 years; females, n=10, 16.30±2.01 years, range = 14-18) agreed to participate. They completed a questionnaire that included the Dominant Achievement Goal assessment instrument, the 2×2 Achievement Goals Questionnaire for Sport (AGQ-S), The Situational Motivation Scale (SIMS) and the Competence subscale of the Basic Psychological Needs in Exercise questionnaire (BPNES). Results indicated that participants overwhelmingly showed mastery-approach achievement goal dominance, and it remained stable at the conclusion of the different training sessions under all intensity levels. This profile was positively correlated to self-determined situational motivation and competence. However, swimmers' feelings of competence increased only after the medium intensity level training session. After the completion of the maximal intensity training session, swimmers' self-determined motivation was significantly lower compared to the other two training sessions, which could be caused by a temporary period of burnout. Results indicated that high-level swimmers had a distinct mastery-approach dominant achievement goal profile that was not affected by the workload of the different training sessions. They also showed high levels of self-determined situational motivation and competence. However, heavy workloads should be controlled because they can cause transitory burnout.

The students would work in small heterogeneous groups (of five to six members) and help one another to comprehend the material given. To achieve the objectives of the study, this research aims to know the effect of STAD on competence of electrical motor installation. The objective of the student competence was knowledge competence. The data was collected from 30 students. the participants were the students of second class at electrical installation techniques, SMKN 1 Pungging Indonesia. The design of empirical test in this research was one shot case study. The result of knowledge test would be compared by criteria for minimum competence, which was 75. Knowledge competence was analyzed with one sample t test technique. From the analysis got average 84.93, which meant average of student competence had reached criteria for minimum competence. From that analyze, It could be concluded that STAD was effective on electrical motor installation knowledge competence. STAD could grow student motivation to learn better than other models. But, in the application of cooperative learning teacher should prepare carefully before the learning process to avoid problems that could arise during group learning such as students who were less active in the groups. The problem could be resolved by away the teachers took around to check each group. It was felt could minimize the problems.

Noise Figure Optimization of Fully Integrated Inductively Degenerated Silicon Germanium HBT LNAs

NASA Astrophysics Data System (ADS)

Ibrahim, Mohamed Farhat

Silicon germanium (SiGe) heterojunction bipolar transistors (HBTs) have the properties of producing very low noise and high gain over a wide bandwidth. Because of these properties, SiGe HBTs have continually improved and now compete with InP and GaAs HEMTs for low-noise amplification. This thesis investigates the theoretical characterizations and optimizations of SiGe HBT low noise amplifiers (LNAs) for low-noise low-power applications, using SiGe BiCMOS (bipolar complementary metal-oxide-semiconductor) technology. The theoretical characterization of SiGe HBT transistors is investigated by a comprehensive study of the DC and small-signal transistor modeling. Based on a selected small-signal model, a noise model for the SiGe HBT transistor is produced. This noise model is used to build a cascode inductively degenerated SiGe HBT LNA circuit. The noise figure (NF) equation for this LNA is derived. This NF equation shows better than 94.4% agreement with the simulation results. With the small-signal model verification, a new analytical method for optimizing the noise figure of the SiGe HBT LNA circuits is presented. The novelty feature of this optimization is the inclusion of the noise contributions of the base inductor parasitic resistance, the emitter inductor parasitic resistance and the bond-wire inductor parasitic resistances. The optimization is performed by reducing the number of design variables as possible. This improved theoretical optimization results in LNA designs that achieve better noise figure performance compared to previously published results in bipolar and BiCMOS technologies. Different design constraints are discussed for the LNA optimization techniques. Three different LNAs are designed. The three designs are fully integrated and fabricated in a single chip to achieve a fully monolithic realization. The LNA designs are experimentally verified. The low noise design produced a NF of 1.5dB, S21 of 15dB, and power consumption of 15mW. The three LNA designs occupied 1.4mum 2 in 130 nm BiCMOS technology.

The Academic Consortium for Complementary and Alternative Health Care (ACCAHC) is committed to advancing human health through the advancement and integration of the complementary and alternative medicine (CAM) professions within the American healthcare system. This will involve the maturation and integration of the licensed CAM professions into conventional healthcare delivery, and in turn, it will involve the development of competency in integrative healthcare and interprofessional education within the CAM professions. In 2010, ACCAHC resolved to identify the competencies necessary for this transformation, and in the process, discovered a parallel process of competency development within conventional healthcare, the Interprofessional Education Collaborative (IPEC), representing the six major conventional healthcare professions. The ACCAHC competency document, its development, and its similarity to the IPEC document are discussed. The ACCAHC competency document identified two domains of competence that were not present in the IPEC document: evidence-informed practice and institutional healthcare practices. These two domains of competency are discussed with respect to their significance in both CAM and conventional healthcare practices. ACCAHC's goal is to foster collaboration among its member professions and with conventional healthcare professions, and to use these competency documents to improve and optimize healthcare delivery, practices, and outcomes in America. It is hoped that ACCAHC's competency document will catalyze interaction with IPEC leading to the adoption of a single shared competency document that will meet the needs of all healthcare providers and educators. © 2013 Elsevier Inc.

Fair performance comparison of different carbon blacks in lithium-sulfur batteries with practical mass loadings - Simple design competes with complex cathode architecture

NASA Astrophysics Data System (ADS)

Jozwiuk, Anna; Sommer, Heino; Janek, Jürgen; Brezesinski, Torsten

2015-11-01

The lithium-sulfur system is one of the most promising next generation battery systems, as elemental sulfur is cheap, abundant and has a high theoretical specific capacity. Although much research is conducted on complex sulfur/carbon composites and architectures, it is difficult to compare the performance of the cathodes to one another. Factors, such as different electrolyte composition and cell components strongly affect the cyclability of the battery. Here, we show the importance of optimizing ;standard; conditions to allow for fair performance comparison of different carbon blacks. Our optimal electrolyte-to-sulfur ratio is 11 μL mgsulfur-1 and high concentrations of LiNO3 (>0.6 M) are needed because nitrate is consumed continuously during cycling. Utilizing these standard conditions, we tested the cycling behavior of four types of cathodes with individual carbon blacks having different specific surface areas, namely Printex-A, Super C65, Printex XE-2 and Ketjenblack EC-600JD. Both the specific capacity and polysulfide adsorption capability clearly correlate with the surface area of the carbon being used. High specific capacities (>1000 mAh gsulfur-1 at C/5) are achieved with high surface area carbons. We also demonstrate that a simple cathode using Ketjenblack EC-600JD as the conductive matrix material can well compete with those having complex architectures or additives.

A novel model-based evolutionary algorithm for multi-objective deformable image registration with content mismatch and large deformations: benchmarking efficiency and quality

NASA Astrophysics Data System (ADS)

Bouter, Anton; Alderliesten, Tanja; Bosman, Peter A. N.

2017-02-01

Taking a multi-objective optimization approach to deformable image registration has recently gained attention, because such an approach removes the requirement of manually tuning the weights of all the involved objectives. Especially for problems that require large complex deformations, this is a non-trivial task. From the resulting Pareto set of solutions one can then much more insightfully select a registration outcome that is most suitable for the problem at hand. To serve as an internal optimization engine, currently used multi-objective algorithms are competent, but rather inefficient. In this paper we largely improve upon this by introducing a multi-objective real-valued adaptation of the recently introduced Gene-pool Optimal Mixing Evolutionary Algorithm (GOMEA) for discrete optimization. In this work, GOMEA is tailored specifically to the problem of deformable image registration to obtain substantially improved efficiency. This improvement is achieved by exploiting a key strength of GOMEA: iteratively improving small parts of solutions, allowing to faster exploit the impact of such updates on the objectives at hand through partial evaluations. We performed experiments on three registration problems. In particular, an artificial problem containing a disappearing structure, a pair of pre- and post-operative breast CT scans, and a pair of breast MRI scans acquired in prone and supine position were considered. Results show that compared to the previously used evolutionary algorithm, GOMEA obtains a speed-up of up to a factor of 1600 on the tested registration problems while achieving registration outcomes of similar quality.

Competence with fractions predicts gains in mathematics achievement.

Competence with fractions predicts later mathematics achievement, but the codevelopmental pattern between fractions knowledge and mathematics achievement is not well understood. We assessed this codevelopment through examination of the cross-lagged relation between a measure of conceptual knowledge of fractions and mathematics achievement in sixth and seventh grades (N=212). The cross-lagged effects indicated that performance on the sixth grade fractions concepts measure predicted 1-year gains in mathematics achievement (ß=.14, p<.01), controlling for the central executive component of working memory and intelligence, but sixth grade mathematics achievement did not predict gains on the fractions concepts measure (ß=.03, p>.50). In a follow-up assessment, we demonstrated that measures of fluency with computational fractions significantly predicted seventh grade mathematics achievement above and beyond the influence of fluency in computational whole number arithmetic, performance on number fluency and number line tasks, central executive span, and intelligence. Results provide empirical support for the hypothesis that competence with fractions underlies, in part, subsequent gains in mathematics achievement. Copyright © 2012 Elsevier Inc.

To assess dental students' achieved competencies and perceived satisfaction with their temporomandibular disorders (TMD) and orofacial pain education and to compare these with the results of their final examination in TMD and orofacial pain. Dental students from two consecutive classes (2011/2012 and 2012/2013) at the Department of Orofacial Pain and Jaw Function at the dental school in Malmö, Sweden completed two self-evaluations, one at the beginning of semester seven and one at the end of semester eight. The questionnaire that they were given concerned achieved competencies and satisfaction with education in TMD and orofacial pain. Items focused on anatomy, physiology, and clinical training. Students estimated their competence and satisfaction on a numeric rating scale and described their idea of treating TMD and orofacial pain patients on a verbal rating scale. Outcome variables were tested with paired samples t test for differences over time and independent samples t test for between-class comparisons; both were adjusted for multiple testing with Bonferroni correction. Significant improvement in all items was observed for achieved competencies and satisfaction in both classes between semester seven and semester eight (P < .05). No differences in competencies or satisfaction occurred between classes at the end of the clinical course in semester eight (P > .05). This study has shown that expansion in undergraduate TMD and orofacial pain education at the dental school in Malmö has allowed all students to develop the same level of competence, independent of prior experience. The study also pointed out that continuous evaluation and enhancement of TMD and orofacial pain education in undergraduate dental education is beneficial.

To give an overview of empirical studies investigating nursing homes as a learning environment during nursing students' clinical practice. A supportive clinical learning environment is crucial to students' learning and for their development into reflective and capable practitioners. Nursing students' experience with clinical practice can be decisive in future workplace choices. A competent workforce is needed for the future care of older people. Opportunities for maximum learning among nursing students during clinical practice studies in nursing homes should therefore be explored. Mixed-method systematic review using PRISMA guidelines, on learning environments in nursing homes, published in English between 2005-2015. Search of CINAHL with Full Text, Academic Search Premier, MEDLINE and SocINDEX with Full Text, in combination with journal hand searches. Three hundred and thirty-six titles were identified. Twenty studies met the review inclusion criteria. Assessment of methodological quality was based on the Mixed Methods Appraisal Tool. Data were extracted and synthesised using a data analysis method for integrative reviews. Twenty articles were included. The majority of the studies showed moderately high methodological quality. Four main themes emerged from data synthesis: "Student characteristic and earlier experience"; "Nursing home ward environment"; "Quality of mentoring relationship and learning methods"; and "Students' achieved nursing competencies." Nursing home learning environments may be optimised by a well-prepared academic-clinical partnership, supervision by encouraging mentors and high-quality nursing care of older people. Positive learning experiences may increase students' professional development through achievement of basic nursing skills and competencies and motivate them to choose the nursing home as their future workplace. An optimal learning environment can be ensured by thorough preplacement preparations in academia and in nursing home wards, continuous supervision and facilitation of team learning. © 2018 John Wiley & Sons Ltd.

The Consortium of Academic Health Centers for Integrative Medicine defines integrative medicine as "the practice of medicine that reaffirms the importance of the relationship between practitioner and patient, focuses on the whole person, is informed by evidence, and makes use of all appropriate therapeutic approaches, health care professionals, and disciplines to achieve optimal health and healing." Over the past three decades, the U.S. public increasingly has sought integrative medicine approaches. In an effort to train medical professionals to adequately counsel patients on the safe and appropriate use of these approaches, medical schools and residencies have developed curricula on integrative medicine for their trainees. In addition, integrative medicine clinical fellowships for postresidency physicians have emerged to provide training for practitioners interested in gaining greater expertise in this emerging field. Currently, 13 clinical fellowships in integrative medicine exist in the United States, and they are predominantly connected to academic medical centers or teaching affiliate hospitals. In 2010, the Consortium of Academic Health Centers for Integrative Medicine, represented by 56 member academic health care institutions with a shared commitment to advance the principles and practices of integrative medicine, convened a two-year task force to draft integrative medicine fellowship core competencies. These competencies would guide fellowship curriculum development and ensure that graduates possessed a common body of knowledge, skills, and attitudes. In this article, the authors discuss the competencies and the task force's process to develop them, as well as associated teaching and assessment methods, faculty development, potential barriers, and future directions.

We tend to think that everyone deserves an equal say in a debate. This seemingly innocuous assumption can be damaging when we make decisions together as part of a group. To make optimal decisions, group members should weight their differing opinions according to how competent they are relative to one another; whenever they differ in competence, an equal weighting is suboptimal. Here, we asked how people deal with individual differences in competence in the context of a collective perceptual decision-making task. We developed a metric for estimating how participants weight their partner's opinion relative to their own and compared this weighting to an optimal benchmark. Replicated across three countries (Denmark, Iran, and China), we show that participants assigned nearly equal weights to each other's opinions regardless of true differences in their competence-even when informed by explicit feedback about their competence gap or under monetary incentives to maximize collective accuracy. This equality bias, whereby people behave as if they are as good or as bad as their partner, is particularly costly for a group when a competence gap separates its members.

Reliability-based structural optimization: A proposed analytical-experimental study

NASA Technical Reports Server (NTRS)

Stroud, W. Jefferson; Nikolaidis, Efstratios

1993-01-01

An analytical and experimental study for assessing the potential of reliability-based structural optimization is proposed and described. In the study, competing designs obtained by deterministic and reliability-based optimization are compared. The experimental portion of the study is practical because the structure selected is a modular, actively and passively controlled truss that consists of many identical members, and because the competing designs are compared in terms of their dynamic performance and are not destroyed if failure occurs. The analytical portion of this study is illustrated on a 10-bar truss example. In the illustrative example, it is shown that reliability-based optimization can yield a design that is superior to an alternative design obtained by deterministic optimization. These analytical results provide motivation for the proposed study, which is underway.

Objective To reach consensus on core competency statements for natural health products (NHPs) for Canadian pharmacy students. Methods Four rounds of a modified Delphi method were used to achieve consensus on core competency statements for NHPs. Pharmacy educators from Canada and the United States, and representatives from Canadian pharmacy organizations ranked their agreement using a 5-point Likert scale. Results Consensus was achieved on 3 NHP-related core competency statements: (1) to incorporate NHP knowledge when providing pharmaceutical care; (2) to access and critically appraise NHP-related information sources; and (3) to provide appropriate education to patients and other health care providers on the effectiveness, potential adverse effects, and drug interactions of NHPs. Conclusions Consensus was reached among leaders in NHP education on 3 NHP-related core competency statements. Implementation of these competencies would ensure that graduating Canadian pharmacists would be able to fulfill their professional responsibilities related to NHPs. PMID:20498738

Early mathematical competencies and later achievement: insights from the Longitudinal Study of Australian Children

NASA Astrophysics Data System (ADS)

MacDonald, Amy; Carmichael, Colin

2017-11-01

International research suggests that early mathematical competence predicts later mathematical achievement. In this article, we explore the relationship between mathematical competencies at 4-5 years, as measured by teacher ratings, and later results on Years 3, 5, 7 and 9 National Assessment Program - Literacy and Numeracy (NAPLAN) numeracy tests. Data from a nationally representative sample of 2343 children participating in the Longitudinal Study of Australian Children (LSAC) are examined. In line with international studies, we report moderate correlations between preschool-entry mathematics and later NAPLAN numeracy test results. However, analysis of individual growth trajectories indicates that early mathematics predicts the initial (Year 3) level, but not subsequent growth. This suggests that early mathematical competencies are important for enhancing achievement in early schooling, but that the quality of mathematics education provided in the schooling years is critical for future development.

Thresholding Based on Maximum Weighted Object Correlation for Rail Defect Detection

NASA Astrophysics Data System (ADS)

Li, Qingyong; Huang, Yaping; Liang, Zhengping; Luo, Siwei

Automatic thresholding is an important technique for rail defect detection, but traditional methods are not competent enough to fit the characteristics of this application. This paper proposes the Maximum Weighted Object Correlation (MWOC) thresholding method, fitting the features that rail images are unimodal and defect proportion is small. MWOC selects a threshold by optimizing the product of object correlation and the weight term that expresses the proportion of thresholded defects. Our experimental results demonstrate that MWOC achieves misclassification error of 0.85%, and outperforms the other well-established thresholding methods, including Otsu, maximum correlation thresholding, maximum entropy thresholding and valley-emphasis method, for the application of rail defect detection.

The objective of this research was to estimate the optimal timing for fertilization to achieve proper embryonic development of in vitro-matured bovine oocytes. First, cumulus-oocyte complexes were subjected to in vitro maturation (IVM) for 14-22 hr. The timing when 50% of oocytes reached metaphase II stage was estimated to be 17.5 hr after IVM start. Next, using oocytes subjected to IVM for 12-30 hr, sperm penetration was examined after 4-18 hr of in vitro fertilization (IVF). A significant negative correlation between IVM duration and the timing when 50% of oocytes were penetrated by sperm after IVF start was observed (P<0.01). Finally, oocytes subjected to 12-30 hr of IVM were inseminated and cultured for 6 days to examine embryonic development. In the group with 22 hr of IVM, the percentages of cleaved embryos and blastocysts were the highest values in all groups. According to the regression equation describing the time from nuclear maturation to sperm penetration (x) and the percentage of blastocysts (y) (y=7.23x - 0.297x(2), P<0.01), the blastocyst rate peaked when sperm penetration occurred at 12.2 hr after achieving nuclear maturation. In conclusion, under the present IVM/IVF conditions, it was estimated that oocytes acquired their highest developmental competence at about 30 hr after IVM start, and thus, the optimal IVM duration was calculated to be about 21 hr.

Joint Contributions of Peer Acceptance and Peer Academic Reputation to Achievement in Academically At Risk Children: Mediating Processes

PubMed Central

Chen, Qi; Hughes, Jan N.; Liew, Jeffrey; Kwok, Oi-Man

2010-01-01

The longitudinal relationships between two dimensions of peer relationships and subsequent academic adjustment were investigated in a sample of 543 relatively low achieving children (M = 6.57 years at Year 1, 1st grade). Latent variable SEM was used to test a four stage model positing indirect effects of peer acceptance and peer academic reputation (PAR) assessed in Year 2 on academic achievement in Year 5, via the effects of the peer relationships variables on perceived academic competence in Year 3 and effortful engagement in Year 4. As expected, the effect of PAR on engagement was partially mediated by perceived academic competence, and the effect of perceived academic competence on achievement was partially mediated by engagement. In the context of PAR, peer acceptance did not contribute to the mediating variables or to achievement. Findings provide a clearer understanding of the processes by which early peer-relationships influence concurrent and future school-related outcomes. Implications for educational practice and future research are discussed. PMID:21113406

Both the "What" and "Why" of Youth Sports Participation Matter; a Conditional Process Analysis.

PubMed

Gjesdal, Siv; Appleton, Paul R; Ommundsen, Yngvar

2017-01-01

This study builds on previous research combining achievement goal orientation from Achievement Goal Theory and motivational regulation from Self-Determination Theory. The aim was to assess the combination of the "what" and "why" of youth sport activity, and how it relates to the need for competence and self-esteem. Achievement goal orientation, specifically task and ego, was employed to represent the "what", whilst intrinsic and external regulation reflected the "why". Based on a sample of 496 youth sports participants, structural equation modeling with a bootstrapping procedure was used to examine whether the indirect relationship between achievement goal orientation and self-esteem was conditional to motivational regulation. The results show partial support for the conditional process models. Specifically, task orientation was indirectly linked with self-esteem through competence need, and the relationship was stronger with higher levels of intrinsic regulation for sport. Furthermore, ego orientation was negatively associated with self-esteem through a positive relationship with competence frustration. However, this relationship emerged only for those higher in intrinsic regulation. External regulation did not emerge as a moderator, but presented a positive relationship with competence frustration. Findings are discussed in light of both Achievement Goal Theory and Self-Determination Theory, and underline the importance of considering both the "what" and "why" when attempting to understand motivation in youth sport.

Splash-cup plants accelerate raindrops to disperse seeds

PubMed Central

Amador, Guillermo J.; Yamada, Yasukuni; McCurley, Matthew; Hu, David L.

2013-01-01

The conical flowers of splash-cup plants Chrysosplenium and Mazus catch raindrops opportunistically, exploiting the subsequent splash to disperse their seeds. In this combined experimental and theoretical study, we elucidate their mechanism for maximizing dispersal distance. We fabricate conical plant mimics using three-dimensional printing, and use high-speed video to visualize splash profiles and seed travel distance. Drop impacts that strike the cup off-centre achieve the largest dispersal distances of up to 1 m. Such distances are achieved because splash speeds are three to five times faster than incoming drop speeds, and so faster than the traditionally studied splashes occurring upon horizontal surfaces. This anomalous splash speed is because of the superposition of two components of momentum, one associated with a component of the drop's motion parallel to the splash-cup surface, and the other associated with film spreading induced by impact with the splash-cup. Our model incorporating these effects predicts the observed dispersal distance within 6–18% error. According to our experiments, the optimal cone angle for the splash-cup is 40°, a value consistent with the average of five species of splash-cup plants. This optimal angle arises from the competing effects of velocity amplification and projectile launching angle. PMID:23235266

Family medicine residency programs require innovative means to assess residents' competence in "soft" skills (eg, patient-centred care, communication, and professionalism) and to identify residents who are having difficulty early enough in their residency to provide remedial training. To develop a method to assess residents' competence in various skills and to identify residents who are having difficulty. The Competency-Based Achievement System (CBAS) was designed to measure competence using 3 main principles: formative feedback, guided self-assessment, and regular face-to-face meetings. The CBAS is resident driven and provides a framework for meaningful interactions between residents and advisors. Residents use the CBAS to organize and review their feedback, to guide their own assessment of their progress, and to discern their future learning needs. Advisors use the CBAS to monitor, guide, and verify residents' knowledge of and competence in important skills. By focusing on specific skills and behaviour, the CBAS enables residents and advisors to make formative assessments and to communicate their findings. Feedback indicates that the CBAS is a user-friendly and helpful system to assess competence.

The Precision Medicine Initiative will accelerate genomic discoveries that improve health care, necessitating a genomic competent workforce. This study assessed leadership team (administrator/educator) year-long interventions to improve registered nurses' (RNs) capacity to integrate genomics into practice. We examined genomic competency outcomes in 8,150 RNs. Awareness and intention to learn more increased compared with controls. Findings suggest achieving genomic competency requires a longer intervention and support strategies such as infrastructure and policies. Leadership played a role in mobilizing staff, resources, and supporting infrastructure to sustain a large-scale competency effort on an institutional basis. Results demonstrate genomic workforce competency can be attained with leadership support and sufficient time. Our study provides evidence of the critical role health-care leaders play in facilitating genomic integration into health care to improve patient outcomes. Genomics' impact on quality, safety, and cost indicate a leader-initiated national competency effort is achievable and warranted. Published by Elsevier Inc.

Academic debate is an effective method to enhance the competences of critical thinking, problem solving, communication skills and cooperation skills. The present study examined the improvement of debate competence which is an outcome of debate-based flipped learning. A questionnaire was administrated to second-year premedical school students at Yeungnam University. In total 45 students participated in the survey. The survey questionnaire was composed of 60 items of eight subfactors on debate competence. To investigate the homogeneous of low and high achievement groups, 18 items on empathy and 75 items on critical thinking scales were used. To compare the pretest with posttest scores, data was analyzed using paired sample t-test. There were no significant differences between low and high achievement groups by average grade at the beginning of the semester. There was a significant improvement in high achievers on the logical argumentation (p<0.001), proficiency in inquiry (p<0.01), active participation (p<0.001), ability to investigate and analyze (p<0.001), observance of debate rules (p<0.05), and acceptability (p<0.05). Even in low achievers, active participation (p<0.05) and ability to investigate and analyze (p<0.01) were significantly improved. Results showed that students could improve their debate competence by the debate-based flipped learning. A prospective and comparative study on the communication and teamwork competences needs to be conducted in the future. It is suggested that in-depth discussion for the curriculum design and teaching will be needed in terms of the effectiveness and the outcomes of the medical humanities.

Purpose: Academic debate is an effective method to enhance the competences of critical thinking, problem solving, communication skills and cooperation skills. The present study examined the improvement of debate competence which is an outcome of debate-based flipped learning. Methods: A questionnaire was administrated to second-year premedical school students at Yeungnam University. In total 45 students participated in the survey. The survey questionnaire was composed of 60 items of eight subfactors on debate competence. To investigate the homogeneous of low and high achievement groups, 18 items on empathy and 75 items on critical thinking scales were used. To compare the pretest with posttest scores, data was analyzed using paired sample t-test. Results: There were no significant differences between low and high achievement groups by average grade at the beginning of the semester. There was a significant improvement in high achievers on the logical argumentation (p<0.001), proficiency in inquiry (p<0.01), active participation (p<0.001), ability to investigate and analyze (p<0.001), observance of debate rules (p<0.05), and acceptability (p<0.05). Even in low achievers, active participation (p<0.05) and ability to investigate and analyze (p<0.01) were significantly improved. Conclusion: Results showed that students could improve their debate competence by the debate-based flipped learning.

2016-01-01

High-risk low-volume therapies are those therapies that are practiced infrequently and yet carry an increased risk to patients because of their complexity. Staff nurses are required to competently manage these therapies to treat patients' unique needs and optimize outcomes; however, maintaining competence is challenging. This article describes implementation of Just-in-Time Training, which requires validation of minimum competency of bedside nurses managing high-risk low-volume therapies through direct observation of a return-demonstration competency checklist.

Lee, Martin J; Whitehead, Jean; Ntoumanis, Nikos; Hatzigeorgiadis, Antonis

2008-10-01

This research examines the value-expressive function of attitudes and achievement goal theory in predicting moral attitudes. In Study 1, the Youth Sport Values Questionnaire (YSVQ; Lee, Whitehead, & Balchin, 2000) was modified to measure moral, competence, and status values. In Study 2, structural equation modeling on data from 549 competitors (317 males, 232 females) aged 12-15 years showed that moral and competence values predicted prosocial attitudes, whereas moral (negatively) and status values (positively) predicted antisocial attitudes. Competence and status values predicted task and ego orientation, respectively, and task and ego orientation partially mediated the effect of competence values on prosocial attitudes and of status values on antisocial attitudes, respectively. The role of sport values is discussed, and new research directions are proposed.

We tend to think that everyone deserves an equal say in a debate. This seemingly innocuous assumption can be damaging when we make decisions together as part of a group. To make optimal decisions, group members should weight their differing opinions according to how competent they are relative to one another; whenever they differ in competence, an equal weighting is suboptimal. Here, we asked how people deal with individual differences in competence in the context of a collective perceptual decision-making task. We developed a metric for estimating how participants weight their partner’s opinion relative to their own and compared this weighting to an optimal benchmark. Replicated across three countries (Denmark, Iran, and China), we show that participants assigned nearly equal weights to each other’s opinions regardless of true differences in their competence—even when informed by explicit feedback about their competence gap or under monetary incentives to maximize collective accuracy. This equality bias, whereby people behave as if they are as good or as bad as their partner, is particularly costly for a group when a competence gap separates its members. PMID:25775532

Using self-determination theory to improve residency training: learning to make omelets without breaking eggs.

PubMed

Hoffman, Benjamin D

2015-04-01

An inherent tension exists in clinical training between supervising learners to ensure quality and patient safety, and allowing learners to practice independently to gain experience. In this issue of Academic Medicine, Biondi and colleagues discuss this tension, highlighting the disconnect between faculty and resident perceptions of autonomous practice for housestaff. They report that each group perceives itself as more competent in its role than does the other group. Their work leads us to consider how medical educators might safely and effectively transform the learning process. Self-determination theory (SDT) holds that there is a human tendency to develop toward self-directed and autonomous regulation of behavior. This development of intrinsic motivation is governed by the complex relationships among autonomy, competence, and relatedness as well as educational content and the learning milieu. Applying an SDT framework to their findings, Biondi and colleagues report that faculty desire from residents the evidence of internal motivation and demonstration of competence and self-confidence that will allow faculty to entrust learners with autonomy. They conclude, however, that these are qualities that faculty find lacking in many residents. To optimize the balance between autonomy and supervision, this Commentary's author proposes the use of "scaffolding," a construct from developmental psychology. In the scaffolding model, the role of teachers is to support the learner's development and to provide support structures to help the learner get to the next stage of entrustment and competence. Achieving a balance is essential to providing the best patient care now and in the future.

To develop a consensus definition for "advocacy for the profession of pharmacy" and core competencies for doctor of pharmacy (PharmD) graduates to be effective advocates for the profession. A 3-round modified Delphi process was conducted using a panel of 9 experts. Participants revised a definition for "advocacy for the profession" and ultimately rated their agreement using a 5-point Likert scale. Competency statements were developed and subsequently rated for importance for being an advocate and importance to address in PharmD curricula. A consensus-derived definition was developed. Two competency statements achieved consensus for both measures of importance. Four competency statements achieved consensus for only 1 measure and another 4 did not reach consensus for either measure. A consensus-derived definition was developed describing advocacy for the profession of pharmacy and began laying the groundwork for the knowledge and skills necessary to be an effective advocate for the profession of pharmacy.

To test and extend the conceptualization of the endorsement of achievement goals in the physical education setting Mastery, Performance-approach, and Performance-approach goals, Perception of the physical education competence, Implicit theory about sport ability, and Perception of the motivational climate were assessed among 682 boys attending five French schools. Analysis indicated that (1) Performance-approach goals were positively associated with perception of physical education Competence, Entity beliefs about sport ability, the Performance dimension of the motivational climate, and negatively associated with Incremental beliefs about sport ability. (2) Mastery goals were positively associated with perception of physical education Competence, Incremental beliefs about sport ability, the Mastery dimension of the motivational climate, and negatively associated with the Performance dimension of the motivational climate. Also, (3) Performance-avoidance goals were positively associated with Entity beliefs about sport ability and the Performance dimension of the motivational climate; these goals were negatively associated with Incremental beliefs about sport ability and perception of physical education Competence. These results clearly attested to the validity of the trichotomous model in the physical education setting.

Sexual and gender minority (SGM) individuals experience high rates of harassment and discrimination when seeking healthcare, which contributes to substantial healthcare disparities. Improving physician training about gender identity, sexual orientation, and the healthcare needs of SGM patients has been identified as a critical strategy for mitigating these disparities. In 2014, the Association of American Medical Colleges (AAMC) published medical education competencies to guide undergraduate medical education on SGM topics. Conduct pilot study to investigate medical student comfort and competence about SGM health competencies outlined by the AAMC and evaluate curricular coverage of SGM topics. Six-hundred and fifty-eight students at New England allopathic medical schools (response rate 21.2%) completed an anonymous, online survey evaluating self-reported comfort and competence regarding SGM health competencies, and coverage of SGM health in the medical curriculum. 92.7% of students felt somewhat or very comfortable treating sexual minorities; 68.4% felt comfortable treating gender minorities. Most respondents felt not competent or somewhat not competent with medical treatment of gender minority patients (76.7%) and patients with a difference of sex development (81%). At seven schools, more than 50% of students indicated that the curriculum neither adequately covers SGM-specific topics nor adequately prepares students to serve SGM patients. The prevalence of self-reported comfort is greater than that of self-reported competence serving SGM patients in a convenience sample of New England allopathic medical students. The majority of participants reported insufficient curricular preparation to achieve the competencies necessary to care for SGM patients. This multi-institution pilot study provides preliminary evidence that further curriculum development may be needed to enable medical students to achieve core competencies in SGM health, as defined by AAMC. Further mixed methods research is necessary to substantiate and expand upon the findings of this pilot study. This pilot study also demonstrates the importance of creating specific evaluation tools to assess medical student achievement of competencies established by the AAMC.

Implant therapy is rapidly becoming a standard of care for replacing missing dentition. Predoctoral dental curricula include some training in the implant restorative phase but offer limited exposure to the surgical phase, so it is important for postdoctoral general dentistry residency programs to provide competency training in all phases of implant therapy. The aim of this study was to determine the training needed for general dentistry residents to achieve competence in this area, specifically by defining the number of clinical experiences necessary in both the surgical and prosthetic phases of implant-retained mandibular overdenture construction (IRMOD). Fifteen Advanced Education in General Dentistry (AEGD) residents at one academic dental institution placed two implants in a total of 50 patients with edentulous mandibles and subsequently restored them with IRMOD. The supervising faculty member and the residents evaluated the competency level on a five-point scale after each implant placement and prosthetic case completion. According to the faculty evaluations, the residents achieved surgical competence after placing two implants in four to six cases and prosthetic management competence after restoring two to four cases of IRMOD. All 50 patients were satisfied with the treatment outcomes of IRMOD. This study concluded that general dentistry residents could potentially achieve competence in both the surgical and prosthetic phases of implant therapy while enrolled in an AEGD program.

There are limited data on learning curves and competence in ERCP. By using a standardized data collection tool, we aimed to prospectively define learning curves and measure competence among advanced endoscopy trainees (AETs) by using cumulative sum (CUSUM) analysis. AETs were evaluated by attending endoscopists starting with the 26th hands-on ERCP examination and then every ERCP examination during the 12-month training period. A standardized ERCP competency assessment tool (using a 4-point scoring system) was used to grade the examination. CUSUM analysis was applied to produce learning curves for individual technical and cognitive components of ERCP performance (success defined as a score of 1, acceptable and unacceptable failures [p1] of 10% and 20%, respectively). Sensitivity analyses varying p1 and by using a less-stringent definition of success were performed. Five AETs were included with a total of 1049 graded ERCPs (mean ± SD, 209.8 ± 91.6/AET). The majority of cases were performed for a biliary indication (80%). The overall and native papilla allowed cannulation times were 3.1 ± 3.6 and 5.7 ± 4, respectively. Overall learning curves demonstrated substantial variability for individual technical and cognitive endpoints. Although nearly all AETs achieved competence in overall cannulation, none achieved competence for cannulation in cases with a native papilla. Sensitivity analyses increased the proportion of AETs who achieved competence. This study demonstrates that there is substantial variability in ERCP learning curves among AETs. A specific case volume does not ensure competence, especially for native papilla cannulation. Copyright © 2016 American Society for Gastrointestinal Endoscopy. Published by Elsevier Inc.

Interprofessional care is an essential part of the health service delivery system. It helps to achieve improved care and to deliver the optimal and desired health outcomes by working together, sharing and learning skills. Health care organisation is a collective sum of many leaders and followers. Successful delivery of interprofessional care relies on the contribution of interprofessional care team leaders and health care professionals from all groups. The role of the interprofessional care team leader is vital to ensuring continuity and consistency of care and to mobilise and motivate health care professionals for the effective delivery of health services. Medical professionals usually lead interprofessional care teams. Interprofessional care leaders require various skills and competencies for the successful delivery of interprofessional care.

Both the “What” and “Why” of Youth Sports Participation Matter; a Conditional Process Analysis

PubMed Central

Gjesdal, Siv; Appleton, Paul R.; Ommundsen, Yngvar

2017-01-01

This study builds on previous research combining achievement goal orientation from Achievement Goal Theory and motivational regulation from Self-Determination Theory. The aim was to assess the combination of the “what” and “why” of youth sport activity, and how it relates to the need for competence and self-esteem. Achievement goal orientation, specifically task and ego, was employed to represent the “what”, whilst intrinsic and external regulation reflected the “why”. Based on a sample of 496 youth sports participants, structural equation modeling with a bootstrapping procedure was used to examine whether the indirect relationship between achievement goal orientation and self-esteem was conditional to motivational regulation. The results show partial support for the conditional process models. Specifically, task orientation was indirectly linked with self-esteem through competence need, and the relationship was stronger with higher levels of intrinsic regulation for sport. Furthermore, ego orientation was negatively associated with self-esteem through a positive relationship with competence frustration. However, this relationship emerged only for those higher in intrinsic regulation. External regulation did not emerge as a moderator, but presented a positive relationship with competence frustration. Findings are discussed in light of both Achievement Goal Theory and Self-Determination Theory, and underline the importance of considering both the “what” and “why” when attempting to understand motivation in youth sport.

The competency of internists in holistic global care to support healthy Indonesia 2010.

Rudijanto, Achmad

2006-01-01

All patients are entitled to good standards of practice and care from their doctors. The improved health of all peoples is the main goal of medical education, including for the education of internal medicine registrars. The future development of the direction and goal of education, the level of competence of internal medicine specialists, and the process of learning will be related to preparing the internal medicine specialist to have global competitive advantage. Identification of general competencies is the first step in a long-term effort designed to emphasize educational outcome, for assessment in residency programs, and in the accreditation process. To achieve that competence, a variety of learning opportunities need to be provided in order that the resident can achieve the necessary knowledge, skills, attitude, and behaviors. Identification of the role and function of internal medicine specialists is needed prior to the development of the general competencies. As educational objectives, the competencies fall into two main categories: knowledge-based and performance-based. Knowledge-based competency has two components, medical knowledge (bio-science and clinical medicine) and contextual knowledge (epidemiology, health service organization, and human behavior). The performance base has two components, intellectual skills and the interpersonal skills. Besides the two main categories of educational objectives, there are behavioral objectives that residents must achieve through the educational program, to ensure that residents are able to deal with a range of prescribed clinical situations effectively, safely, humanely, and economically. The achievement of behavioral objectives will ensure, at least in part, that the doctor will implement good medical practice. The index clinical/community situations (ICS) on which the educational objectives will be based are taken from diseases and illnesses that occur in clinical and community settings. No resident can master all medicine there is to know, as there are no limits to what can be known about medicine. It is important to make choices in selecting what residents should learn by analyzing the ICS.

A divide-and-conquer approach to determine the Pareto frontier for optimization of protein engineering experiments.

PubMed

He, Lu; Friedman, Alan M; Bailey-Kellogg, Chris

2012-03-01

In developing improved protein variants by site-directed mutagenesis or recombination, there are often competing objectives that must be considered in designing an experiment (selecting mutations or breakpoints): stability versus novelty, affinity versus specificity, activity versus immunogenicity, and so forth. Pareto optimal experimental designs make the best trade-offs between competing objectives. Such designs are not "dominated"; that is, no other design is better than a Pareto optimal design for one objective without being worse for another objective. Our goal is to produce all the Pareto optimal designs (the Pareto frontier), to characterize the trade-offs and suggest designs most worth considering, but to avoid explicitly considering the large number of dominated designs. To do so, we develop a divide-and-conquer algorithm, Protein Engineering Pareto FRontier (PEPFR), that hierarchically subdivides the objective space, using appropriate dynamic programming or integer programming methods to optimize designs in different regions. This divide-and-conquer approach is efficient in that the number of divisions (and thus calls to the optimizer) is directly proportional to the number of Pareto optimal designs. We demonstrate PEPFR with three protein engineering case studies: site-directed recombination for stability and diversity via dynamic programming, site-directed mutagenesis of interacting proteins for affinity and specificity via integer programming, and site-directed mutagenesis of a therapeutic protein for activity and immunogenicity via integer programming. We show that PEPFR is able to effectively produce all the Pareto optimal designs, discovering many more designs than previous methods. The characterization of the Pareto frontier provides additional insights into the local stability of design choices as well as global trends leading to trade-offs between competing criteria.

Professional groups, such as IFAPP (International Federation of Pharmaceutical Physicians and Pharmaceutical Medicine), are expected to produce the defined core competencies to orient the discipline and the academic programs for the development of future competent professionals and to advance the profession. On the other hand, PharmaTrain, an Innovative Medicines Initiative project, has become the largest public-private partnership in biomedicine in the European Continent and aims to provide postgraduate courses that are designed to meet the needs of professionals working in medicines development. A working group was formed within IFAPP including representatives from PharmaTrain, academic institutions and national member associations, with special interest and experience on Quality Improvement through education. The objectives were: to define a set of core competencies for pharmaceutical physicians and drug development scientists, to be summarized in a Statement of Competence and to benchmark and align these identified core competencies with the Learning Outcomes (LO) of the PharmaTrain Base Course. The objectives were successfully achieved. Seven domains and 60 core competencies were identified and aligned accordingly. The effective implementation of training programs using the competencies or the PharmaTrain LO anywhere in the world may transform the drug development process to an efficient and integrated process for better and safer medicines. The PharmaTrain Base Course might provide the cognitive framework to achieve the desired Statement of Competence for Pharmaceutical Physicians and Drug Development Scientists worldwide.

Lopez, Cristina M; Begle, Angela Moreland; Dumas, Jean E; de Arellano, Michael A

2012-03-01

This study evaluated the effects of abuse potential in parents on subsequent coping competence domains in their children, using a model empirically supported in a high-risk community sample by Moreland and Dumas (2007). Data from an ethnically diverse sample of 579 parents enrolled in the PACE (Parenting Our Children to Excellence) program was used to evaluate whether parental child abuse potential assessed at pre-intervention negatively contributed to child affective, achievement, and social coping competence in preschoolers one year later, and whether these associations were moderated by sex or ethnicity. Cross-sectional results indicated that parental child abuse potential was negatively related to child affective and achievement coping competence, after accounting for variance associated with child behavior problems. However, child abuse potential was not predictive of subsequent coping competence in any domain after controlling for previous levels of child coping competence. No moderating effects were found for sex and ethnicity, but results showed main effects of sex and ethnicity in cross-sectional analyses. Clinical implications and future directions are discussed.

We are living in a time with a lot of changes in which health organizations have more challenges to face. One of them is to recognize, strengthen, develop and retain the talent they have. Competency-based human resources management is emerging as a tool that contributes to achieve that aim. Competencies from the generic or characteristic perspective: personality traits, values and motivations, which are deeply rooted in the person. Through elaborating a competencies map for the organization, and identifying the job competencies profile, above all in key jobs, the employees know what it is going to expect from them. After, detect and cover the learning needs, it is possible to achieve better adjust between worker-job. The nursing unit manager is a key job because it is a link between management team and nursing team. The way that it is performed, it will have impact on the quality of care and its team motivation. So, the most adequate person who covers this job would have a part of knowledge, skills, attitudes and compatible interests with her job. Competency-based management helps identify both the potential and learning needs to performing this job.

The pediatric hospital medicine (PHM) core competencies were established in 2010 to identify the specific knowledge base and skill set needed to provide the highest quality of care for hospitalized children. The objectives of this study were to examine the perceived core competency achievements of fellowship-trained and non-fellowship-trained early career pediatric hospitalists and identify perceived gaps in our current training models. An anonymous Web-based survey was distributed in November 2013. Hospitalists within 5 years of their residency graduation reported their perceived competency in select PHM core competencies. χ(2) and multiprobit regression analyses were utilized. One hundred ninety-seven hospitalists completed the survey and were included; 147 were non-fellowship-trained and 50 were PHM fellowship graduates or current PHM fellows. Both groups reported feeling less than competent in sedation and aspects of business practice. Non-fellowship-trained hospitalists also reported mean scores in the less than competent range in intravenous access/phlebotomy, technology-dependent emergencies, performing Plan-Do-Study-Act process and root cause analysis, defining basic statistical terms, and identifying research resources. Non-fellowship-trained hospitalists reported mean competency scores greater than fellowship-trained hospitalists in pain management, newborn care, and transitions in care. Early career pediatric hospitalists report deficits in several of the PHM core competencies, which should be considered when designing PHM-specific training in the future. Fellowship-trained hospitalists report higher levels of perceived competency in many core areas. © 2015 Society of Hospital Medicine.

The Royal College of Physicians and Surgeons of Canada requires emergency medicine (EM) residency programs to meet training objectives relating to administration and leadership. The purpose of this study was to establish a national consensus on the competencies for inclusion in an EM administration and leadership curriculum. A modified Delphi process involving two iterative rounds of an electronic survey was used to achieve consensus on competencies for inclusion in an EM administration and leadership curriculum. An initial list of competencies was compiled using peer-reviewed and grey literature. The participants included 14 EM residency program directors and 43 leadership and administration experts from across Canada who were recruited using a snowball technique. The proposed competencies were organized using the CanMEDS Physician Competency Framework and presented in English or French. Consensus was defined a priori as >70% agreement. Nearly all (13 of 14) of the institutions with an FRCPC EM program had at least one participant complete both surveys. Thirty-five of 57 (61%) participants completed round 1, and 30 (53%) participants completed both rounds. Participants suggested an additional 16 competencies in round 1. The results of round 1 informed the decisions in round 2. Fifty-nine of 109 (54.1%) competencies achieved consensus for inclusion. Based on a national modified Delphi process, we describe 59 competencies for inclusion in an EM administration and leadership curriculum that was arranged by CanMEDS Role. EM educators may consider these competencies when designing local curricula.

The education of UK specialised neonatal nurses: reviewing the rationale for creating a standard competency framework.

PubMed

Turrill, Sue

2014-09-01

This paper examines the influences surrounding formal education provision for specialised neonatal nurses in the UK and presents a standardised clinical competency framework in response. National drivers for quality neonatal care define links to the numbers and ratios of specialised neonatal nurses in practice. Historical changes to professional nursing governance have led to diversity in supporting education programmes, making achievement of a standard level of clinical competence for this element of the nursing workforce difficult. In addition responsibility for funding specialised education and training has moved from central to local hospital level. Evaluating these key influences on education provision rationalised the development, by a UK professional consensus group, of a criteria based framework to be utilised by both formal education and service providers. The process identified clinical competency (in terms of unique knowledge and skills), evidence of achievement, and quality education principles. Access to specialised education relies on the availability of programmes of study and clear funding strategies. Creating a core syllabus for education provides a tool to standardise course content, commission education and audit clinical competency. In addition partnerships between healthcare and education providers become successful in achieving standard specialised education for neonatal nurses. Copyright © 2014 Elsevier Ltd.

Sperm competition games: optimal sperm allocation in response to the size of competing ejaculates.

PubMed

Engqvist, Leif; Reinhold, Klaus

2007-01-22

Sperm competition theory predicts that when males are certain of sperm competition, they should decrease sperm investment in matings with an increasing number of competing ejaculates. How males should allocate sperm when competing with differently sized ejaculates, however, has not yet been examined. Here, we report the outcomes of two models assuming variation in males' sperm reserves and males being faced with different amounts of competing sperm. In the first 'spawning model', two males compete instantaneously and both are able to assess the sperm competitive ability of each other. In the second 'sperm storage model', males are sequentially confronted with situations involving different levels of sperm competition, for instance different amounts of sperm already stored by the female mating partner. In both of the models, we found that optimal sperm allocation will strongly depend on the size of the male's sperm reserve. Males should always invest maximally in competition with other males that are equally strong competitors. That is, for males with small sperm reserves, our model predicts a negative correlation between sperm allocation and sperm competition intensity, whereas for males with large sperm reserves, this correlation is predicted to be positive.

Feasibility and Outcomes of Implementing a Portfolio Assessment System Alongside a Traditional Grading System.

2016-11-01

Portfolios are a powerful tool to collect and evaluate evidence of medical students' competence across time. However, comprehensive portfolio assessment systems that are implemented alongside traditional graded curricula at medical schools in the United States have not been described in the literature. This study describes the development and implementation of a longitudinal competency-based electronic portfolio system alongside a graded curriculum at a relatively large U.S. medical school. In 2009, the authors developed a portfolio system that served as a repository for all student assessments organized by competency domain. Five competencies were selected for a preclerkship summative portfolio review. Students submitted reflections on their performance. In 2014, four clinical faculty members participated in standard-setting activities and used expert judgment and holistic review to rate students' competency achievement as "progressing toward competence," "progressing toward competence with some concern," or "progressing toward competence pending remediation." Follow-up surveys measured students' and faculty members' perceptions of the process. Faculty evaluated 156 portfolios and showed high levels of agreement in their ratings. The majority of students achieved the "progressing toward competence" benchmark in all competency areas. However, 31 students received at least one concerning rating, which was not reflected in their course grades. Students' perceptions of the system's ability to foster self-assessment were mixed. The portfolio review process allowed faculty to identify students with a concerning rating in a behavioral competency who would not have been identified in a traditional grading system. Identification of these students allows for intervention and early remediation.

The relationship of parenting styles and social competency to Type A behavior in children.

Harralson, T L; Lawler, K A

1992-10-01

This study examined parenting styles, Type A behavior in parents and children, and social competence in children. Fifty 1st-6th grade children, parents, and their teachers participated. Type A behavior in parents was associated with a controlling style of parenting, but not with pressuring the child to achieve. Parenting styles of achievement pressure and high control were related to impatient and aggressive behaviors in children, as measured by the MYTH, a teacher-scored Type A behavior instrument. In addition, impatience and aggressiveness in the children were negatively correlated with the child's social competency and ability to function in school. Parenting practices, Type A behavior, and social competency in children may play important roles in the origins of detrimental components of Type A behavior, such as impatience and aggression.

A harvesting fishery model is proposed to analyze the effects of the presence of red devil fish population, as a predator in an ecosystem. In this paper, we consider an ecological model of three species by taking into account two competing species and presence of a predator (red devil), the third species, which incorporates the harvesting efforts of each fish species. The stability of the dynamical system is discussed and the existence of biological and bionomic equilibrium is examined. The optimal harvest policy is studied and the solution is derived in the equilibrium case applying Pontryagin's maximal principle. The simulation results is presented to simulate the dynamical behavior of the model and show that the optimal equilibrium solution is globally asymptotically stable. The results show that the optimal harvesting effort is obtained regarding to bionomic and biological equilibrium.

The Computer Book of the Internal Medicine resident (CBIMR) is a computer program that was validated to analyze the acquisition of competences in teams of Internal Medicine residents. To analyze the characteristics of the rotations during the Internal Medicine residency and to identify the variables associated with the acquisition of clinical and communication skills, the achievement of learning objectives and resident satisfaction. All residents of our service (n=20) participated in the study during a period of 40 months. The CBIMR consisted of 22 self-assessment questionnaires specific for each rotation, with items on services (clinical workload, disease protocolization, resident responsibilities, learning environment, service organization and teamwork) and items on educational outcomes (acquisition of clinical and communication skills, achievement of learning objectives, overall satisfaction). Associations between services features and learning outcomes were analyzed using bivariate and multivariate analysis. An intense clinical workload, high resident responsibilities and disease protocolization were associated with the acquisition of clinical skills. High clinical competence and teamwork were both associated with better communication skills. Finally, an adequate learning environment was associated with increased clinical competence, the achievement of educational goals and resident satisfaction. Potentially modifiable variables related with the operation of clinical services had a significant impact on the acquisition of clinical and communication skills, the achievement of educational goals, and resident satisfaction during the specialized training in Internal Medicine.

Victoroff, Kristin Zakariasen; Boyatzis, Richard E

2013-04-01

Emotional intelligence has emerged as a key factor in differentiating average from outstanding performers in managerial and leadership positions across multiple business settings, but relatively few studies have examined the role of emotional intelligence in the health care professions. The purpose of this study was to examine the relationship between emotional intelligence (EI) and dental student clinical performance. All third- and fourth-year students at a single U.S. dental school were invited to participate. Participation rate was 74 percent (100/136). Dental students' EI was assessed using the Emotional Competence Inventory-University version (ECI-U), a seventy-two-item, 360-degree questionnaire completed by both self and other raters. The ECI-U measured twenty-two EI competencies grouped into four clusters (Self-Awareness, Self-Management, Social Awareness, and Relationship Management). Clinical performance was assessed using the mean grade assigned by clinical preceptors. This grade represents an overall assessment of a student's clinical performance including diagnostic and treatment planning skills, time utilization, preparation and organization, fundamental knowledge, technical skills, self-evaluation, professionalism, and patient management. Additional variables were didactic grade point average (GPA) in Years 1 and 2, preclinical GPA in Years 1 and 2, Dental Admission Test academic average and Perceptual Ability Test scores, year of study, age, and gender. Multiple linear regression analyses were conducted. The Self-Management cluster of competencies (b=0.448, p<0.05) and preclinical GPA (b=0.317, p<0.01) were significantly correlated with mean clinical grade. The Self-Management competencies were emotional self-control, achievement orientation, initiative, trustworthiness, conscientiousness, adaptability, and optimism. In this sample, dental students' EI competencies related to Self-Management were significant predictors of mean clinical grade assigned by preceptors. Emotional intelligence may be an important predictor of clinical performance, which has important implications for students' development during dental school.

Investigating multi-objective fluence and beam orientation IMRT optimization

Radiation Oncology treatment planning requires compromises to be made between clinical objectives that are invariably in conflict. It would be beneficial to have a ‘bird’s-eye-view’ perspective of the full spectrum of treatment plans that represent the possible trade-offs between delivering the intended dose to the planning target volume (PTV) while optimally sparing the organs-at-risk (OARs). In this work, the authors demonstrate Pareto-aware radiotherapy evolutionary treatment optimization (PARETO), a multi-objective tool featuring such bird’s-eye-view functionality, which optimizes fluence patterns and beam angles for intensity-modulated radiation therapy (IMRT) treatment planning. The problem of IMRT treatment plan optimization is managed as a combined monolithic problem, where all beam fluence and angle parameters are treated equally during the optimization. To achieve this, PARETO is built around a powerful multi-objective evolutionary algorithm, called Ferret, which simultaneously optimizes multiple fitness functions that encode the attributes of the desired dose distribution for the PTV and OARs. The graphical interfaces within PARETO provide useful information such as: the convergence behavior during optimization, trade-off plots between the competing objectives, and a graphical representation of the optimal solution database allowing for the rapid exploration of treatment plan quality through the evaluation of dose-volume histograms and isodose distributions. PARETO was evaluated for two relatively complex clinical cases, a paranasal sinus and a pancreas case. The end result of each PARETO run was a database of optimal (non-dominated) treatment plans that demonstrated trade-offs between the OAR and PTV fitness functions, which were all equally good in the Pareto-optimal sense (where no one objective can be improved without worsening at least one other). Ferret was able to produce high quality solutions even though a large number of parameters, such as beam fluence and beam angles, were included in the optimization.

To provide a synthesis of literature on international policy concerning professional regulation in nursing and midwifery, with reference to routes of entry into training and pathways to licensure. Internationally, there is evidence of multiple points of entry into initial training, multiple divisions of the professional register and multiple pathways to licensure. Policy documents and commentary articles concerned with models of initial training and pathways to licensure were reviewed. Item selection, quality appraisal and data extraction were undertaken and documentary analysis was performed on all retrieved texts. Case studies of five Western countries indicate no single uniform system of routes of entry into initial training and no overall consensus regarding the optimal model of initial training. Multiple regulatory systems, with multiple routes of entry into initial training and multiple pathways to licensure pose challenges, in terms of achieving commonly-agreed understandings of practice competence. The variety of models of initial training present nursing managers with challenges in the recruitment and deployment of personnel trained in many different jurisdictions. Nursing managers need to consider the potential for considerable variation in competency repertoires among nurses trained in generic and specialist initial training models.

De novo self-assembling collagen heterotrimers using explicit positive and negative design.

We sought to computationally design model collagen peptides that specifically associate as heterotrimers. Computational design has been successfully applied to the creation of new protein folds and functions. Despite the high abundance of collagen and its key role in numerous biological processes, fibrous proteins have received little attention as computational design targets. Collagens are composed of three polypeptide chains that wind into triple helices. We developed a discrete computational model to design heterotrimer-forming collagen-like peptides. Stability and specificity of oligomerization were concurrently targeted using a combined positive and negative design approach. The sequences of three 30-residue peptides, A, B, and C, were optimized to favor charge-pair interactions in an ABC heterotrimer, while disfavoring the 26 competing oligomers (i.e., AAA, ABB, BCA). Peptides were synthesized and characterized for thermal stability and triple-helical structure by circular dichroism and NMR. A unique A:B:C-type species was not achieved. Negative design was partially successful, with only A + B and B + C competing mixtures formed. Analysis of computed versus experimental stabilities helps to clarify the role of electrostatics and secondary-structure propensities determining collagen stability and to provide important insight into how subsequent designs can be improved.

Water Market-scale Agricultural Planning: Promoting Competing Water Resource Use Efficiency Through Agro-Economics

NASA Astrophysics Data System (ADS)

Delorit, J. D.; Block, P. J.

2017-12-01

Where strong water rights law and corresponding markets exist as a coupled econo-legal mechanism, water rights holders are permitted to trade allocations to promote economic water resource use efficiency. In locations where hydrologic uncertainty drives the assignment of annual per-water right allocation values by water resource managers, collaborative water resource decision making by water rights holders, specifically those involved in agricultural production, can result in both resource and economic Pareto efficiency. Such is the case in semi-arid North Chile, where interactions between representative farmer groups, treated as competitive bilateral monopolies, and modeled at water market-scale, can provide both price and water right allocation distribution signals for unregulated, temporary water right leasing markets. For the range of feasible per-water right allocation values, a coupled agricultural-economic model is developed to describe the equilibrium distribution of water, the corresponding market price of water rights and the net surplus generated by collaboration between competing agricultural uses. Further, this research describes a per-water right inflection point for allocations where economic efficiency is not possible, and where price negotiation among competing agricultural uses is required. An investigation of the effects of water right supply and demand inequality at the market-scale is completed to characterize optimal market performance under existing water rights law. The broader insights of this research suggest that water rights holders engaged in agriculture can achieve economic benefits from forming crop-type cooperatives and by accurately assessing the economic value of allocation.

2013-01-01

Dental trauma occurs frequently in children and often can lead to pulpal necrosis. The occurrence of pulpal necrosis in the permanent but immature tooth represents a challenging clinical situation since the thin and often short roots increase the risk of subsequent fracture. Current approaches for treating the traumatized immature tooth with pulpal necrosis do not reliably achieve the desired clinical outcomes, consisting of healing of apical periodontitis, promotion of continued root development and restoration of the functional competence of pulpal tissue. An optimal approach for treating the immature permanent tooth with a necrotic pulp would be to regenerate functional pulpal tissue. This review summarizes the current literature supporting a biological rationale for considering regenerative endodontic treatment procedures in treating the immature permanent tooth with pulp necrosis.

Motherhood: a potential source of bias in employment decisions.

Heilman, Madeline E; Okimoto, Tyler G

2008-01-01

Results of 2 experimental studies in which job incumbents were said to be applying for promotions to traditionally male positions demonstrated bias against mothers in competence expectations and in screening recommendations. This bias occurred regardless of whether the research participants were students (Study 1) or working people (Study 2). Although anticipated job commitment, achievement striving, and dependability were rated as generally lower for parents than for nonparents, anticipated competence was uniquely low for mothers. Mediational analyses indicated that, as predicted, negativity in competence expectations, not anticipated job commitment or achievement striving, promoted the motherhood bias in screening recommendations; expected deficits in agentic behaviors, not in dependability, were found to fuel these competence expectations. These findings suggest that motherhood can indeed hinder the career advancement of women and that it is the heightened association with gender stereotypes that occurs when women are mothers that is the source of motherhood's potentially adverse consequences. 2008 APA

Quantum optimal control of isomerization dynamics of a one-dimensional reaction-path model dominated by a competing dissociation channel

NASA Astrophysics Data System (ADS)

2009-07-01

Quantum wave packet optimal control simulations with intense laser pulses have been carried out for studying molecular isomerization dynamics of a one-dimensional (1D) reaction-path model involving a dominant competing dissociation channel. The 1D intrinsic reaction coordinate model mimics the ozone open→cyclic ring isomerization along the minimum energy path that successively connects the ozone cyclic ring minimum, the transition state (TS), the open (global) minimum, and the dissociative O2+O asymptote on the O3 ground-state A1' potential energy surface. Energetically, the cyclic ring isomer, the TS barrier, and the O2+O dissociation channel lie at ˜0.05, ˜0.086, and ˜0.037 hartree above the open isomer, respectively. The molecular orientation of the modeled ozone is held constant with respect to the laser-field polarization and several optimal fields are found that all produce nearly perfect isomerization. The optimal control fields are characterized by distinctive high temporal peaks as well as low frequency components, thereby enabling abrupt transfer of the time-dependent wave packet over the TS from the open minimum to the targeted ring minimum. The quick transition of the ozone wave packet avoids detrimental leakage into the competing O2+O channel. It is possible to obtain weaker optimal laser fields, resulting in slower transfer of the wave packets over the TS, when a reduced level of isomerization is satisfactory.

An assessment of workplace programmes designed to control inhalation risks using respiratory protective equipment.

Few studies have assessed respiratory protective equipment (RPE) failures at the organizational level despite evidence to suggest that compliance with good practice may be low. The aim of this study was to develop an understanding of what current RPE programmes look like across industry and how this compares with good practice. Twenty cross-industry site visits were conducted with companies that had RPE programmes in place. Visits involved management interviews to explore current RPE systems and procedures and the decision making underpinning these. Observations of RPE operatives were included followed by short interviews to discuss the behaviours observed. Post-site assessments jointly undertaken by an RPE scientist and psychologist produced ratings for each site on six critical aspects of RPE programmes (knowledge/awareness, selection, use, training/information, supervision, and storage/cleaning/maintenance). Overall ratings for theoretical competence (i.e. management knowledge of RPE) and practical control (i.e. actual RPE practice on the shop floor) were also given. Qualitative analysis was performed on all interview data. The performance of RPE programmes varied across industry. Fewer than half the companies visited were considered to have an acceptable level of theoretical competence and practical control. Four distinct groups emerged from the 20 sites studied, ranging from Learners (low theoretical competence and practical control--four sites), Developers (acceptable theoretical competence and low practical control--five sites), and Fortuitous (low theoretical competence and acceptable practical control--two sites), to Proficient (acceptable theoretical competence and practical control--nine sites). None of the companies visited were achieving optimal control through the use of RPE. Widespread inadequacies were found with programme implementation, particularly training, supervision, and maintenance. Our taxonomy based on the four groups (Learners, Developers, Fortuitous, and Proficient) provided a useful expert-informed tool for explaining the variation in performance of RPE programmes across industry. Although further research and development are required, this taxonomy offers a useful starting point for the development of practical tools that may assist managers in making the much-needed improvements to all facets of programme implementation, particularly training, supervision, and maintenance.

Competency-based curricula have been implemented at the Medical College of Georgia to prepare students to meet entry level competencies as physical therapists and physical therapist assistants. Criteria-referenced evaluations are used to determine if students have achieved the desired competencies. Performance is measured against the criteria and not other students. The process of developing the system currently in use at the Medical College of Georgia is delineated in some detail and some of the advantages of the system for physical therapy education are discussed.

Intensity inhomogeneity compensation and tissue segmentation for magnetic resonance imaging with noise-suppressed multiplicative intrinsic component optimization

NASA Astrophysics Data System (ADS)

Dong, Huaipeng; Zhang, Qi; Shi, Jun

2017-12-01

Magnetic resonance (MR) images suffer from intensity inhomogeneity. Segmentation-based approaches can simultaneously achieve both intensity inhomogeneity compensation (IIC) and tissue segmentation for MR images with little noise, but they often fail for images polluted by severe noise. Here, we propose a noise-robust algorithm named noise-suppressed multiplicative intrinsic component optimization (NSMICO) for simultaneous IIC and tissue segmentation. Considering the spatial characteristics in an image, an adaptive nonlocal means filtering term is incorporated into the objective function of NSMICO to decrease image deterioration due to noise. Then, a fuzzy local factor term utilizing the spatial and gray-level relationship among local pixels is embedded into the objective function to reach a balance between noise suppression and detail preservation. Experimental results on synthetic natural and MR images with various levels of intensity inhomogeneity and noise, as well as in vivo clinical MR images, have demonstrated the effectiveness of the NSMICO and its superiority to three competing approaches. The NSMICO could be potentially valuable for MR image IIC and tissue segmentation.

Optimizing Rubisco and its regulation for greater resource use efficiency.

Carmo-Silva, Elizabete; Scales, Joanna C; Madgwick, Pippa J; Parry, Martin A J

Rubisco catalyses the carboxylation of ribulose-1,5-bisphosphate (RuBP), enabling net CO2 assimilation in photosynthesis. The properties and regulation of Rubisco are not optimal for biomass production in current and projected future environments. Rubisco is relatively inefficient, and large amounts of the enzyme are needed to support photosynthesis, requiring large investments in nitrogen. The competing oxygenation of RuBP by Rubisco decreases photosynthetic efficiency. Additionally, Rubisco is inhibited by some sugar phosphates and depends upon interaction with Rubisco activase (Rca) to be reactivated. Rca activity is modulated by the chloroplast redox status and ADP/ATP ratios, thereby mediating Rubisco activation and photosynthetic induction in response to irradiance. The extreme thermal sensitivity of Rca compromises net CO2 assimilation at moderately high temperatures. Given its central role in carbon assimilation, the improvement of Rubisco function and regulation is tightly linked with irradiance, nitrogen and water use efficiencies. Although past attempts have had limited success, novel technologies and an expanding knowledge base make the challenge of improving Rubisco activity in crops an achievable goal. Strategies to optimize Rubisco and its regulation are addressed in relation to their potential to improve crop resource use efficiency and climate resilience of photosynthesis. © 2014 Rothamsted Research Ltd.

Identifying public health competencies relevant to family medicine.

PubMed

Harvey, Bart J; Moloughney, Brent W; Iglar, Karl T

2011-10-01

Public health situations faced by family physicians and other primary care practitioners, such as severe acute respiratory syndrome (SARS) and more recently H1N1, have resulted in an increased interest to identify the public health competencies relevant to family medicine. At present there is no agreed-on set of public health competencies delineating the knowledge and skills that family physicians should possess to effectively face diverse public health challenges. Using a multi-staged, iterative process that included a detailed literature review, the authors developed a set of public health competencies relevant to primary care, identifying competencies relevant across four levels, from "post-MD" to "enhanced." Feedback from family medicine and public health educator-practitioners regarding the set of proposed "essential" competencies indicated the need for a more limited, feasible set of "priority" areas to be highlighted during residency training. This focused set of public health competencies has begun to guide relevant components of the University of Toronto's Family Medicine Residency Program curriculum, including academic half-days; clinical experiences, especially identifying "teachable moments" during patient encounters; resident academic projects; and elective public health agency placements. These competencies will also be used to guide the development of a family medicine-public health primer and faculty development sessions to support family medicine faculty facilitating residents to achieve these competencies. Once more fully implemented, an evaluation will be initiated to determine the degree to which these public health competencies are being achieved by family medicine graduates, especially whether they attained the knowledge, skills, and confidence necessary to effectively face diverse public health situations-from common to emergent.

Perceived and actual academic competence in maltreated children.

PubMed

Kinard, E M

2001-01-01

The aims were twofold: 1) to determine whether maltreated and nonmaltreated children differed in the accuracy of their self-assessments of academic achievement; and 2) to determine whether discrepancies between perceived and actual academic competence were related to perceptions of social support from mothers, teachers, and peers. A sample of 195 maltreated children known to a state protective service agency was compared to a control group of 179 nonmaltreated children. The groups were matched on child's gender, age, ethnicity, and birth order; socioeconomic ranking of neighborhood; and family structure. Although maltreated children had significantly lower achievement scores than did nonmal-treated children, the two groups did not differ on perceived academic competence. With regard to discrepancies between perceived and actual competence, maltreated children were more likely than nonmaltreated children to overestimate their level of competence, particularly for reading and arithmetic. Overall, children who reported low maternal support were more likely to overestimate reading competence than were those who reported average or high maternal support. When maltreatment status was considered, maltreated children with low support seemed likely to overestimate abilities, whereas nonmaltreated children with low support seemed likely to underestimate competence. Maltreated children may overestimate their academic abilities in order to compensate for self-perceptions of low self-worth. Efforts to improve academic performance in maltreated children should focus not only on increasing academic skills but also on enhancing self-esteem.

This study evaluated direct relations of both kindergarteners' (N = 301) naturalistically observed emotion in 2 different school contexts and early kindergarten verbal competence to academic adjustment (i.e., standardized measures of academic achievement, teacher-reported academic skills, teacher-reported and observed school engagement) and if these relations were mediated by teacher-reported conflict with students and by peer acceptance. When controlling for verbal competence, positive emotions expressed in the classroom context positively directly predicted academic skills, whereas positive emotions expressed outside class (lunch/recess) negatively predicted academic skills. Negative emotions observed in the classroom context and during lunch/recess negatively predicted academic achievement. Positive emotions observed in both contexts indirectly predicted higher school engagement through its positive relation to peer acceptance; positive emotions expressed in lunch and recess indirectly predicted higher school engagement via lower teacher-student conflict. Negative emotions observed in both contexts also indirectly predicted lower school engagement via higher teacher-student conflict. Furthermore, verbal competence indirectly predicted higher academic adjustment via lower teacher-student conflict. Moreover, verbal competence moderated the association between peer acceptance (but not teacher-student conflict) and academic adjustment. Because verbal competence moderated the associations from peer competence, positive emotions in both contexts indirectly predicted higher academic adjustment via higher peer acceptance primarily for children with low, but not high, initial verbal competence.

The development of appropriate water management strategies requires, in part, a methodology for quantifying and evaluating the impact of water policy decisions on regional stakeholders. In this work, we describe the framework we are developing to enhance the body of resources available to policy makers, farmers, and other community members in their e orts to understand, quantify, and assess the often competing objectives water consumers have with respect to usage. The foundation for the framework is the construction of a simulation-based optimization software tool using two existing software packages. In particular, we couple a robust optimization software suite (DAKOTA) with the USGS MF-OWHM water management simulation tool to provide a flexible software environment that will enable the evaluation of one or multiple (possibly competing) user-defined (or stakeholder) objectives. We introduce the individual software components and outline the communication strategy we defined for the coupled development. We present numerical results for case studies related to crop portfolio management with several defined objectives. The objectives are not optimally satisfied for any single user class, demonstrating the capability of the software tool to aid in the evaluation of a variety of competing interests.

Fish, pathogen and environment are three counterparts who are sharing the same circle of life. To keep fish up to their optimal health, environment should be competently improved and pathogen count/virulence should be seized. Using of bioactive immunostimulants to achieve these objectives is the hypothesis under assessment. Thus, the present study was performed to evaluate the use of shrimp shells derived chitosan as an immunostimulant as well as preventive regime against Aeromonas hydrophila infection of Nile tilapia and to assess its antibacterial/aquatic bio-remediating effects. Results achieved by feeding 1% chitosan as preventive/therapeutic regimes have revealed a remarkably enhanced several innate immunological parameters (e.g., Phagocytic activity/index, NBT, Lysozyme activity and ACH50), increased resistance against A. hydrophila and strikingly improved water quality compared to the 0.5 and 2% chitosan containing diets. Conclusively, experimental results suggest the commercial usage of chitosan as an efficient immunostimulant and bio-remediating agent in aquaculture. Copyright © 2015 Elsevier Ltd.

2015-01-01

One of the goals of the AES Life Support Systems Project is to achieve 98% water loop closure for long-duration human exploration missions. Brine water recovery is the primary technology gap that must be bridged to realize this goal. In response to an Agency call for technologies to compete in an October down-select, Capi-BRIC was chosen through a JSC down-select as the strongest candidate to go forward. This resulted in a period of intense development to increase its TRL in preparation for the Agency down-select. This was achieved through rapid prototype design, fabrication, and test at JSC and in a zero-g drop tower at Portland State University. INNOVATION CapiBRIC takes a novel approach of optimizing the containment geometry to support capillary flow and static phase separation to enable evaporation in a microgravity environment. OUTCOME TRL was advanced from 3 to 4, and was selected for continued funding through the AES program. CapiBRIC is poised for development into an ISS technology demonstration, proving its viability as an enabling technology for exploration.

Mo-Si-B alloys for ultrahigh-temperature structural applications.

PubMed

Lemberg, J A; Ritchie, R O

2012-07-10

A continuing quest in science is the development of materials capable of operating structurally at ever-increasing temperatures. Indeed, the development of gas-turbine engines for aircraft/aerospace, which has had a seminal impact on our ability to travel, has been controlled by the availability of materials capable of withstanding the higher-temperature hostile environments encountered in these engines. Nickel-base superalloys, particularly as single crystals, represent a crowning achievement here as they can operate in the combustors at ~1100 °C, with hot spots of ~1200 °C. As this represents ~90% of their melting temperature, if higher-temperature engines are ever to be a reality, alternative materials must be utilized. One such class of materials is Mo-Si-B alloys; they have higher density but could operate several hundred degrees hotter. Here we describe the processing and structure versus mechanical properties of Mo-Si-B alloys and further document ways to optimize their nano/microstructures to achieve an appropriate balance of properties to realistically compete with Ni-alloys for elevated-temperature structural applications.

In the United States, medical students must demonstrate a standard level of “cultural competence,” upon graduation. Cultural competence is most often defined as a set of congruent behaviors, attitudes, and policies that come together in a system, organization, or among professionals that enables effective work in cross-cultural situations. The Association of American Medical Colleges developed the Tool for Assessing Cultural Competence Training (TACCT) to assist schools in developing and evaluating cultural competence curricula to meet these requirements. This review uses the TACCT as a guideline to describe and assess pedagogical approaches to cultural competence training in US medical education and identify content gaps and opportunities for curriculum improvement. A total of 18 programs are assessed. Findings support previous research that cultural competence training can improve the knowledge, attitudes, and skills of medical trainees. However, wide variation in the conceptualization, implementation, and evaluation of cultural competence training programs exists, leading to differences in training quality and outcomes. More research is needed to establish optimal approaches to implementing and evaluating cultural competence training that incorporate cultural humility, the social determinants of health, and broader structural competency within the medical system.

In the investigation of the effect of attention deficit hyperactivity disorder (ADHD) symptoms on school careers there is a need to study the role of adolescent and childhood ADHD symptoms and academic achievement, and to incorporate measures that include the individual's perspective. Our aim was to gain an overview of the long-term development of school careers in relation to ADHD symptoms. We studied associations between ADHD symptoms and academic achievement at different time-points and future orientation at the end of high school, and assessed the role of self-perceptions of academic competence in these associations. Participants were 192 children (47% girls) with a range of ADHD symptoms taken from a community sample. Collecting data at three time points, in 6th, 11th and 12th grade we tested a structural equation model. Results showed that ADHD symptoms in 6th grade negatively affected academic achievement concurrently and longitudinally. ADHD symptoms in 11th grade negatively affected concurrent academic achievement and academic self-perception and future orientation in 12th grade. Academic achievement had a positive influence on academic self-perception and future orientation. Given the other factors, self-perception of academic competence did not contribute to outcomes. We concluded that early ADHD symptoms may cast long shadows on young people's academic progress. This happens mainly by way of stability in symptoms and relations to early low academic achievement. © 2013 The Authors.

Hylton, Ann C.; Justice, Michael

2016-01-01

Objective. To identify and address areas for curricular improvement by evaluating student achievement of expected learning outcomes and competencies on annual milestone examinations. Design. Students were tested each professional year with a comprehensive milestone examination designed to evaluate student achievement of learning outcomes and professional competencies using a combination of multiple-choice questions, standardized patient assessments (SPAs), and objective structured clinical examination (OSCE) questions. Assessment. Based on student performance on milestone examinations, curricular changes were instituted, including an increased emphasis on graded comprehensive cases, OSCE skills days, and use of patient simulation in lecture and laboratory courses. After making these changes, significant improvements were observed in second and third-year pharmacy students’ grades for the therapeutic case and physician interaction/errors and omissions components of the milestone examinations. Conclusion. Results from milestone examinations can be used to identify specific areas in which curricular improvements are needed to foster student achievement of learning outcomes and professional competencies.

2007-01-01

Background Although effective teamwork has been consistently identified as a requirement for enhanced clinical outcomes in the provision of healthcare, there is limited knowledge of what makes health professionals effective team members, and even less information on how to develop skills for teamwork. This study identified critical teamwork competencies for health service managers. Methods Members of a state branch of the professional association of Australian health service managers participated in a teamwork survey. Results The 37% response rate enabled identification of a management teamwork competency set comprising leadership, knowledge of organizational goals and strategies and organizational commitment, respect for others, commitment to working collaboratively and to achieving a quality outcome. Conclusion Although not part of the research question the data suggested that the competencies for effective teamwork are perceived to be different for management and clinical teams, and there are differences in the perceptions of effective teamwork competencies between male and female health service managers. This study adds to the growing evidence that the focus on individual skill development and individual accountability and achievement that results from existing models of health professional training, and which is continually reinforced by human resource management practices within healthcare systems, is not consistent with the competencies required for effective teamwork.

To evaluate the effectiveness of a preoperative skills curriculum, and to assess and document competence in associated Obstetrics and Gynecology Level 1 Milestones. The Decision to Incision curriculum was developed by a team of medical educators with the goal of teaching and evaluating 5 skills pertinent to Milestone 1: Preoperative consent, patient positioning, Foley catheter placement, surgical scrub, and preoperative time-out. Competence, overall skill performance, and knowledge were assessed by evaluator rating using checklists before and after the educational intervention. Differences between preintervention and postintervention skills performance and competence were assessed using Wilcoxon rank test and Fisher exact test, respectively. Clinical Simulation Center at an academic medical center. Overall, 29 fourth year medical students matriculating into Obstetrics and Gynecology residencies. The proportion of participants meeting Milestone competence significantly increased in all 5 skills, with competence achieved in 95.6% (95% CI: 92.1-99.0) of posttest skills assessments. Median overall performance also significantly improved for all 5 skills, with 83.6% (95% CI: 77.3-89.9) earning scores of 4 out of 5 or greater on the posttest. For knowledge testing, the proportion of correct responses significantly increased for both topics evaluated, from 45.2% to 99.7% (p < 0.0001) for positioning and from 32.8% to 83.1% (p < 0.0001) for time-out. The decision to incision curriculum significantly improved preoperative skills, including skills that may be required on day 1 of residency. This curriculum also facilitated achievement and documentation of competence in multiple Milestones. Copyright © 2016 Association of Program Directors in Surgery. Published by Elsevier Inc.

An innovative approach to enhance dermatology competencies for advanced practice nurses: service–learning with a migrant farm worker health clinic.

PubMed

Downes, Elizabeth A; Connor, Ann; Howett, Maeve

2014-12-01

The purpose of this article is to describe a novel service–learning opportunity for graduate nursing students that promotes competency in dermatology. A hybrid service–learning course with online didactic content is described, along with tools for evaluation of dermatology competencies. Student evaluation of the course is discussed, and selected research articles are reviewed. Advanced practice nursing and medical education frequently does not adequately prepare primary care providers to be competent in the assessment and management of dermatologic conditions. Embedding dermatology content in a service–learning program can optimize the provision of care, strengthen competencies in dermatology and inter-professional care, and allow students to gain a deeper understanding of the population with which they work. The innovative service–learning program presented is a model for advanced practice nursing education. Tools for evaluating clinical competency and courses often need validation.

Admiral nursing competency project: practice development and action research.

PubMed

Dewing, Jan; Traynor, Victoria

2005-07-01

Admiral Nurses are specialist dementia care nurses working in the community with carers of those who have a dementia. The aim of the competency project (2000-2003) was threefold. Firstly to work collaboratively with these specialist nurses to facilitate the development a competency framework that reflects the needs of the Admiral Nursing Service. Secondly, to provide a way to structure evidence demonstrating evolving competency. Thirdly, to specifically enable the nurses to demonstrate evidence of achieving the UK Nursing and Midwifery Council's Higher Level Practice standard. The two complementary approaches of emancipatory action research and systematic practice development were adopted. Methods were taken from action research and systematic practice development approaches with an emphasis on promoting and enabling enlightenment, critical reflection, ownership and creating the best conditions for long-term commitment to the competency framework. The main outcome from this project was the development of a specialist nursing competency framework. The Admiral Nurses' Competency Framework is made up of a set of eight core competencies with three levels of competency statements, loosely structured around the Higher Level Practice standard, and guidance documentation to illustrate how work-based evidence can be generated to demonstrate competence. There were also process-derived outcomes associated with combining systematic practice development with emancipatory action research that had an impact on the culture. The main outcomes here were that practitioners engaged in and experienced learning about how to research their own practice and the consequences of doing this. They also learnt about specialist nursing practice more widely than Admiral Nursing. Finally, there was some increase in awareness about the culture within their teams and organizations. The final competency framework reflects the needs of the service, is owned by the majority of practitioners and project commissioners and this has had a positive impact on implementation. In this paper, we report on combining systematic practice development with action research to achieve immediate project aims. In addition we show how a project of this nature can contribute to developing skills in practitioners necessary for cultural changes in practice and contributes to wider issues of modernization within nursing and health care. This competency framework will enable Admiral Nurses to demonstrate their level of specialist practice, as individuals and collectively as a service and it also promotes the principles of nurses as life long learners. This may have relevance to other groups of specialist nurses. The project has widespread relevance for two reasons. Firstly, it shows that nurses can be involved in designing and testing a competency framework as collaborators. Secondly, that to achieve this within the spirit of approaches, such as systematic practice development and action research, can be testing for all collaborators even were there is a shared or espoused aim.

Lisowski, Paul W.; Gallmeier, Franz; Guber, Klaus

The 1L Target Moderator Reflector System (TMRS) at the Lujan Center will need to be replaced before the CY 2020 operating cycle. A Physics Division design team investigated options for improving the overall target performance for nuclear science research with minimal reduction in performance for materials science. This review concluded that devoting an optimized arrangement of the Lujan TMRS upper tier to nuclear science and using the lower tier for materials science can achieve those goals. This would open the opportunity for enhanced nuclear science research in an important neutron energy range for NNSA. There will be no other facilitymore » in the US that will compete in the keV energy range provided flight paths and instrumentation are developed to take advantage of the neutron flux and resolution.« less

``Physics and the girly girl—there is a contradiction somewhere'': doctoral students' positioning around discourses of gender and competence in physics

NASA Astrophysics Data System (ADS)

Gonsalves, Allison J.

2014-06-01

Doctoral physics students have stories about what kinds of actions, behaviours and ways of doing physics allow individuals to be recognized as physicists. Viewing a physics department as a case study, and individual participants as embedded cases, this study used a sociocultural approach to examine the ways doctoral students construct these stories about becoming physicists. Through observations, photo-elicitation, and life history interviews, eleven men and women shared stories about their experiences with physics, and the contexts that have enabled or constrained their trajectories into doctoral physics. The results of this study revealed the salience of recognition in the constitution of physicist identities; but how recognition was achieved often entailed the reproduction or reworking of persistent discourses of gender norms. Various interchangeable forms of competence (technical, analytical, and academic) emerged as assets that can be used to achieve recognition in this physics community. However, competence was not the only means by which one might be recognized as a physicist. Contributing to the possibility for recognition was the performance of stereotypical Discourses for physicist that relied on traditional gender norms for the field. The results demonstrated that achieving recognition as a competent physicist often involved a complex negotiation of gender roles and the practice of physics.

Emotional intelligence as a basis for self-esteem in young adults.

PubMed

Cheung, Chau-Kiu; Cheung, Hoi Yan; Hue, Ming-Tak

2015-01-01

As self-esteem is likely to build on favorable social experiences, such as those derived from achievement (i.e., GPA) and social competence, emotional intelligence is likely to be pivotal in fostering social experiences conducive to self-esteem. Accordingly, emotional intelligence is likely to underlie social competence and mediate the contribution of achievement to self-esteem. This uncharted role is the focus of this study, which surveyed 405 undergraduates in Hong Kong, China. Results demonstrated the pivotal role of emotional intelligence. Essentially, emotional intelligence appeared to be a strong determinant of self-esteem and explain away the positive effect of social competence on self-esteem. The results imply the value of raising emotional intelligence in order to consolidate the basis for the young adult's self-esteem.

Background The scientific community increasingly is recognizing the need to bolster standards of data analysis given the widespread concern that basic mistakes in data analysis are contributing to the irreproducibility of many published research findings. The aim of this study was to investigate students’ attitudes towards statistics within a multi-site medical educational context, monitor their changes and impact on student achievement. In addition, we performed a systematic review to better support our future pedagogical decisions in teaching applied statistics to medical students. Methods A validated Serbian Survey of Attitudes Towards Statistics (SATS-36) questionnaire was administered to medical students attending obligatory introductory courses in biostatistics from three medical universities in the Western Balkans. A systematic review of peer-reviewed publications was performed through searches of Scopus, Web of Science, Science Direct, Medline, and APA databases through 1994. A meta-analysis was performed for the correlation coefficients between SATS component scores and statistics achievement. Pooled estimates were calculated using random effects models. Results SATS-36 was completed by 461 medical students. Most of the students held positive attitudes towards statistics. Ability in mathematics and grade point average were associated in a multivariate regression model with the Cognitive Competence score, after adjusting for age, gender and computer ability. The results of 90 paired data showed that Affect, Cognitive Competence, and Effort scores demonstrated significant positive changes. The Cognitive Competence score showed the largest increase (M = 0.48, SD = 0.95). The positive correlation found between the Cognitive Competence score and students’ achievement (r = 0.41; p<0.001), was also shown in the meta-analysis (r = 0.37; 95% CI 0.32–0.41). Conclusion Students' subjective attitudes regarding Cognitive Competence at the beginning of the biostatistics course, which were directly linked to mathematical knowledge, affected their attitudes at the end of the course that, in turn, influenced students' performance. This indicates the importance of positively changing not only students’ cognitive competency, but also their perceptions of gained competency during the biostatistics course. PMID:27764123

Interpersonal competencies: Responsiveness, technique, and training in psychotherapy.

PubMed

Hatcher, Robert L

2015-11-01

Professional practice in psychology is anchored in interpersonal or relational skills. These skills are essential to successful interactions with clients and their families, students, and colleagues. Expertise in these skills is desired and expected for the practicing psychologist. An important but little-studied aspect of interpersonal skills is what Stiles and colleagues (Stiles, Honos-Webb, & Surko, 1998; Stiles, 2009, 2013) have called appropriate responsiveness. In treatment relationships, appropriate responsiveness is the therapist's ability to achieve optimal benefit for the client by adjusting responses to the current state of the client and the interaction. This article was designed to clarify this aspect of responsiveness, showing its links to empathy, illustrating how responsiveness has been detected in controlled clinical trials, discussing how educators and supervisors have worked to enhance students' responsiveness, and considering how appropriate responsiveness has been assessed. The article also discusses the development of skills underlying appropriate responsiveness and the role of stable differences in talent in training of professional psychologists. Notwithstanding other pessimistic reports on psychologists' expertise, demonstrable expertise may exist in the effective, responsive use of these skills in treatment settings. Appropriate responsiveness may be a variety of executive functioning, organizing and guiding the use of many specific competencies. As such it may be a metacompetency, with implications for the design of competency schemes. Key to all of these considerations is the distinction between therapeutic techniques and their responsive use, which involves astute judgment as to when and how to utilize these responses to best effect in the treatment situation.

The Utility of Reflective Writing after a Palliative Care Experience: Can We Assess Medical Students' Professionalism?

PubMed Central

Gill, Anne C.; Teal, Cayla R.; Morrison, Laura J.

2013-01-01

Abstract Background Medical education leaders have called for a curriculum that proactively teaches knowledge, skills, and attitudes required for professional practice and have identified professionalism as a competency domain for medical students. Exposure to palliative care (PC), an often deeply moving clinical experience, is an optimal trigger for rich student reflection, and students' reflective writings can be explored for professional attitudes. Objective Our aim was to evaluate the merit of using student reflective writing about a PC clinical experience to teach and assess professionalism. Methods After a PC patient visit, students wrote a brief reflective essay. We explored qualitatively if/how evidence of students' professionalism was reflected in their writing. Five essays were randomly chosen to develop a preliminary thematic structure, which then guided analysis of 30 additional, randomly chosen essays. Analysts coded transcripts independently, then collaboratively, developed thematic categories, and selected illustrative quotes for each theme and subtheme. Results Essays revealed content reflecting more rich information about students' progress toward achieving two professionalism competencies (demonstrating awareness of one's own perspectives and biases; demonstrating caring, compassion, empathy, and respect) than two others (displaying self-awareness of performance; recognizing and taking actions to correct deficiencies in one's own behavior, knowledge, and skill). Conclusions Professional attitudes were evident in all essays. The essays had limited use for formal summative assessment of professionalism competencies. However, given the increasing presence of PC clinical experiences at medical schools nationwide, we believe this assessment strategy for professionalism has merit and deserves further investigation.

2018-05-01

The preliminary study shows that many students are difficult to master the concept of physics. There are still many students who have not mastery learning physics. Teachers and students still use textbooks. Students rarely do experiments in the laboratory. One model of learning that can improve students’ competence is a research-based learning with Predict- Observe-Explain (POE) strategies. To implement this learning, research-based physics learning modules with POE strategy are used. The research aims to find out the effectiveness of implementation of research-based physics learning modules with POE strategy to improving the students’ competence. The research used a quasi-experimental with pretest-posttest group control design. Data were collected using observation sheets, achievement test, skill assessment sheets, questionnaire of attitude and student responses to learning implementation. The results of research showed that research-based physics learning modules with POE strategy was effective to improve the students’ competence, in the case of (1) mastery learning of physics has been achieved by majority of students, (2) improving the students competency of experimental class including high category, (3) there is a significant difference between the average score of students’ competence of experimental class and the control class, (4) the average score of the students competency of experimental class is higher than the control class, (5) the average score of the students’ responses to the learning implementation is very good category, this means that most students can implement research-based learning with POE strategies.

A guide to multi-objective optimization for ecological problems with an application to cackling goose management

USGS Publications Warehouse

Williams, Perry J.; Kendall, William L.

2017-01-01

Choices in ecological research and management are the result of balancing multiple, often competing, objectives. Multi-objective optimization (MOO) is a formal decision-theoretic framework for solving multiple objective problems. MOO is used extensively in other fields including engineering, economics, and operations research. However, its application for solving ecological problems has been sparse, perhaps due to a lack of widespread understanding. Thus, our objective was to provide an accessible primer on MOO, including a review of methods common in other fields, a review of their application in ecology, and a demonstration to an applied resource management problem.A large class of methods for solving MOO problems can be separated into two strategies: modelling preferences pre-optimization (the a priori strategy), or modelling preferences post-optimization (the a posteriori strategy). The a priori strategy requires describing preferences among objectives without knowledge of how preferences affect the resulting decision. In the a posteriori strategy, the decision maker simultaneously considers a set of solutions (the Pareto optimal set) and makes a choice based on the trade-offs observed in the set. We describe several methods for modelling preferences pre-optimization, including: the bounded objective function method, the lexicographic method, and the weighted-sum method. We discuss modelling preferences post-optimization through examination of the Pareto optimal set. We applied each MOO strategy to the natural resource management problem of selecting a population target for cackling goose (Branta hutchinsii minima) abundance. Cackling geese provide food security to Native Alaskan subsistence hunters in the goose's nesting area, but depredate crops on private agricultural fields in wintering areas. We developed objective functions to represent the competing objectives related to the cackling goose population target and identified an optimal solution first using the a priori strategy, and then by examining trade-offs in the Pareto set using the a posteriori strategy. We used four approaches for selecting a final solution within the a posteriori strategy; the most common optimal solution, the most robust optimal solution, and two solutions based on maximizing a restricted portion of the Pareto set. We discuss MOO with respect to natural resource management, but MOO is sufficiently general to cover any ecological problem that contains multiple competing objectives that can be quantified using objective functions.

Rizany, Ichsan; Hariyati, Rr Tutik Sri; Handayani, Hanny

2018-02-01

To investigate factors affecting the development of nursing competency based on a review of the literature. A systematic review was utilized. The articles were taken from the databases of Pro-Quest, ScienceDirect, SpringerLink, and Scopus. They were retrieved using the following keywords: nursing competence, nurse competencies and clinical competence. Twenty-one papers were selected. Competence development is a continuous process of improving knowledge, attitudes and skills, and is influenced by a myriad of factors. Six factors were identified that affected the development of nursing competence in our systematic review: (1) work experience, (2) type of nursing environment, (3) educational level achieved, (4) adherence to professionalism, (5) critical thinking, and (6) personal factors. Work experience and education were shown to significantly influence the development of competency of nurses. Nurse managers need to support staffing competence through ongoing education, mentoring-preceptorship training, and case-reflection-discussion teaching programs.

2018-03-01

The purpose of this article is to discuss the term of “conceptual understanding” in science education curriculum in Indonesia. The implementation of 2013 Curriculum focuses on the acquisition of contextual knowledge in respective areas and environments. The curriculum seeks to develop students' evaluation skills in three areas: attitude, technical skills, and scientific knowledge. It is based on two layers of competencies: core and basic competencies. The core competencies in the curriculum 2013 represent the ability level to achieve the gradute competency standards of a students at each grade level. There are four mandatory core competencies for all educational levels and all subjects including science, which are spiritual, social, knowledge and skills competencies. In terms of knowledge competencies, conceptual understanding is an inseparable part of science concept since conceptual understanding is one of the basic competencies in science learning. This competency is a part of science graduation standard indicated in MoEC article number 20 in 2016. Therefore, conceptual understanding is needed by students for learning science successfully.

Objective The aim of this study was to compare vitrification optimization of mouse embryos using electron microscopy (EM) grid, cryotop, and thin plastic strip (TPS) containers by evaluating developmental competence and apoptosis rates. Methods Mouse embryos were obtained from superovulated mice. Mouse cleavage-stage, expanded, hatching-stage, and hatched-stage embryos were cryopreserved in EM grid, cryotop, and TPS containers by vitrification in 15% ethylene glycol, 15% dimethylsulfoxide, 10 µg/mL Ficoll, and 0.65 M sucrose, and 20% serum substitute supplement (SSS) with basal medium, respectively. For the three groups in which the embryos were thawed in the EM grid, cryotop, and TPS containers, the thawing solution consisted of 0.25 M sucrose, 0.125 M sucrose, and 20% SSS with basal medium, respectively. Rates of survival, re-expansion, reaching the hatched stage, and apoptosis after thawing were compared among the three groups. Results Developmental competence after thawing of vitrified expanded and hatching-stage blastocysts using cryotop and TPS methods were significantly higher than survival using the EM grid (p<0.05). Also, apoptosis positive nuclei rates after thawing of vitrified expanded blastocysts using cryotop and TPS were significantly lower than when using the EM grid (p<0.05). Conclusion The TPS vitrification method has the advantages of achieving a high developmental ability and effective preservation. PMID:23346525

This 6-week longitudinal study aimed to examine a moderated mediation model that may explain the link between school-related social support (i.e., teacher support and classmate support) and optimal subjective well-being in school among adolescents (n = 1316). Analyses confirmed the hypothesized model that scholastic competence partially mediated the relations between school-related social support and subjective well-being in school, and social acceptance moderated the mediation process in the school-related social support--> subjective well-being in school path and in the scholastic competence--> subjective well-being in school path. The findings suggested that both social contextual factors (e.g., school-related social support) and self-system factors (e.g., scholastic competence and social acceptance) are crucial for adolescents' optimal subjective well-being in school. Limitations and practical applications of the study were discussed. Copyright © 2015 The Foundation for Professionals in Services for Adolescents. Published by Elsevier Ltd. All rights reserved.

Castillo, Richard J; Guo, Kristina L

2011-01-01

Increased racial and ethnic diversity in the United States brings challenges and opportunities for health care organizations to provide culturally competent services that effectively meet the needs of diverse populations. The need to provide more culturally competent care is essential to reducing and eliminating health disparities among minorities. By removing barriers to cultural competence and placing a stronger emphasis on culture in health care, health care organizations will be better able to address the unique health care needs of minorities. Organizations should assess cultural differences, gain greater cultural knowledge, and provide cultural competence training to deliver high-quality services. This article develops a framework to guide health care organizations as they focus on establishing culturally competent strategies and implementing best practices aimed to improve quality of care and achieve better outcomes for minority populations.

2013-08-01

Focused assessment of the gastric antrum by ultrasound is a feasible tool to evaluate the quality of the stomach content. We aimed to determine the amount of training an anesthesiologist would need to achieve competence in the bedside ultrasound technique for qualitative assessment of gastric content. Six anesthesiologists underwent a teaching intervention followed by a formative assessment; then learning curves were constructed. Participants received didactic teaching (reading material, picture library, and lecture) and an interactive hands-on workshop on live models directed by an expert sonographer. The participants were instructed on how to perform a systematic qualitative assessment to diagnose one of three distinct categories of gastric content (empty, clear fluid, solid) in healthy volunteers. Individual learning curves were constructed using the cumulative sum method, and competence was defined as a 90% success rate in a series of ultrasound examinations. A predictive model was further developed based on the entire cohort performance to determine the number of cases required to achieve a 95% success rate. Each anesthesiologist performed 30 ultrasound examinations (a total of 180 assessments), and three of the six participants achieved competence. The average number of cases required to achieve 90% and 95% success rates was estimated to be 24 and 33, respectively. With appropriate training and supervision, it is estimated that anesthesiologists will achieve a 95% success rate in bedside qualitative ultrasound assessment after performing approximately 33 examinations.

To develop benchmark scores of competency for use within a competency based virtual reality (VR) robotic training curriculum. This longitudinal, observational study analysed results from nine European Association of Urology hands-on-training courses in VR simulation. In all, 223 participants ranging from novice to expert robotic surgeons completed 1565 exercises. Competency was set at 75% of the mean expert score. Benchmark scores for all general performance metrics generated by the simulator were calculated. Assessment exercises were selected by expert consensus and through learning-curve analysis. Three basic skill and two advanced skill exercises were identified. Benchmark scores based on expert performance offered viable targets for novice and intermediate trainees in robotic surgery. Novice participants met the competency standards for most basic skill exercises; however, advanced exercises were significantly more challenging. Intermediate participants performed better across the seven metrics but still did not achieve the benchmark standard in the more difficult exercises. Benchmark scores derived from expert performances offer relevant and challenging scores for trainees to achieve during VR simulation training. Objective feedback allows both participants and trainers to monitor educational progress and ensures that training remains effective. Furthermore, the well-defined goals set through benchmarking offer clear targets for trainees and enable training to move to a more efficient competency based curriculum. © 2016 The Authors BJU International © 2016 BJU International Published by John Wiley & Sons Ltd.

Autonomy, Competence and Non-interference.

PubMed

Roberts, Joseph T F

2017-12-30

In light of the variety of uses of the term autonomy in recent bioethics literature, in this paper, I suggest that competence, not being as contested, is better placed to play the anti-paternalistic role currently assigned to autonomy. The demonstration of competence, I will argue, can provide individuals with robust spheres of non-interference in which they can pursue their lives in accordance with their own values. This protection from paternalism is achieved by granting individuals rights to non-interference upon demonstration of competence. In this paper, I present a risk-sensitive account of competence as a means of grounding rights to non-interference. On a risk-sensitive account of competence individuals demonstrate their competence by exercising three capacities to the extent necessary to meet a threshold determined by the riskiness of the decision. These three capacities are the capacity to (i) acquire knowledge, (ii) use instrumental rationality, and (iii) form and revise a life plan.

Educational interventions to enhance competencies for interprofessional collaboration among nurse and physician managers: An integrative review.

PubMed

Clausen, Christina; Cummins, Kelly; Dionne, Kelley

2017-11-01

Collaborative leadership and management structures are critical to transforming care delivery. Both nurse and physician managers are uniquely positioned to co-lead. However, little is known on how to prepare and support individuals for these co-leader arrangements. The re-design of healthcare professional education focuses on interprofessional collaboration, mutual learning, and a competency-based approach. While competencies for interprofessional collaboration have been delineated, competencies for collaborative management practice have yet to be addressed. An integrative review of empirical studies on existing educational interventions was conducted to critically appraise and synthesise the results regarding collaborative competence among nurse and physician leaders. We reviewed how these interventions have been designed, implemented, and evaluated within workplace settings in order to inform our understanding of what components are effective or ineffective for the future development of an educational programme. This review reports on key characteristics of nine empirical studies and emphasises that: a uniprofessional approach to leadership development is predominant within educational programmes and that the assessment of shared learning experiences are not addressed; there are inconsistency in terms used to describe competencies by individual researchers and limitations within the competency frameworks used in the studies reviewed; and there is a lack of suitable instruments available to assess whether competencies have been achieved through the educational programmes. None of the studies discussed the process of how individuals learned specific competencies or whether learning outcome were achieved. Educational programmes were developed based on a perceived lack of leadership preparation and orientation programmes for leaders in formal management positions and used multiple interventions. Only two of the programmes involved organisational or systems level competencies. Interprofessional co-leading requires enhanced capabilities and capacity for managers. There is a need for developing an in-action education intervention that addresses the unique learning needs of co-leader arrangements particularly among nurses and physicians who are new to their role.

2015-08-01

To determine and compare the effects of two different retraining strategies on nursing students' acquisition and retention of BLS/AED skills. Nursing students (N = 177) from two European universities were randomly assigned to either an instructor-directed (IDG) or a student-directed (SDG) 4-h retraining session in BLS/AED. A multiple-choice questionnaire, the Cardiff Test, Laerdal SkillReporter(®) software and a self-efficacy scale were used to assess students' overall competency (knowledge, psychomotor skills and self-efficacy) in BLS/AED at pre-test, post-test and 3-month retention-test. GEE, chi-squared and McNemar tests were performed to examine statistical differences amongst groups across time. There was a significant increase in the proportion of students who achieved competency for all variables measuring knowledge, psychomotor skills and self-efficacy between pre-test and post-test in both groups (all p-values<0.05). However, at post-test, significantly more students in the SDG achieved overall BLS/AED competency when compared to IDG. In terms of retention at 3 months, success rates of students within the IDG deteriorated significantly for all variables except ≥ 70% of chest compressions with correct hand position (p-value = 0.12). Conversely, the proportion of students who achieved competency within the SDG only decreased significantly in 'mean no flow-time ≤ 5s' (p-value = 0.02). Furthermore, differences between groups' success rates at retention-test also proved to be significantly different for all variables measured (all p-values < 0.05). This study demonstrated that using a student-directed strategy to retrain BLS/AED skills has resulted in a higher proportion of nursing students achieving and retaining competency in BLS/AED at three months when compared to an instructor-directed strategy.

2011-04-01

Pattern recognition-based control of myoelectric prostheses has shown great promise in research environments, but has not been optimized for use in a clinical setting. To explore the relationship between classification error, controller delay, and real-time controllability, 13 able-bodied subjects were trained to operate a virtual upper-limb prosthesis using pattern recognition of electromyogram (EMG) signals. Classification error and controller delay were varied by training different classifiers with a variety of analysis window lengths ranging from 50 to 550 ms and either two or four EMG input channels. Offline analysis showed that classification error decreased with longer window lengths (p < 0.01 ). Real-time controllability was evaluated with the target achievement control (TAC) test, which prompted users to maneuver the virtual prosthesis into various target postures. The results indicated that user performance improved with lower classification error (p < 0.01 ) and was reduced with longer controller delay (p < 0.01 ), as determined by the window length. Therefore, both of these effects should be considered when choosing a window length; it may be beneficial to increase the window length if this results in a reduced classification error, despite the corresponding increase in controller delay. For the system employed in this study, the optimal window length was found to be between 150 and 250 ms, which is within acceptable controller delays for conventional multistate amplitude controllers.

This longitudinal study examined relationships between student-perceived teaching for meaning, support for autonomy, and competence in mathematic classrooms (Time 1), and students' achievement goal orientations and engagement in mathematics 6 months later (Time 2). We tested whether student-perceived instructional characteristics at Time 1 indirectly related to student engagement at Time 2, via their achievement goal orientations (Time 2), and, whether student gender moderated these relationships. Participants were ninth and tenth graders (55.2% girls) from 46 classrooms in ten secondary schools in Berlin, Germany. Only data from students who participated at both timepoints were included (N = 746 out of total at Time 1 1118; dropout 33.27%). Longitudinal structural equation modeling showed that student-perceived teaching for meaning and support for competence indirectly predicted intrinsic motivation and effort, via students' mastery goal orientation. These paths were equivalent for girls and boys. The findings are significant for mathematics education, in identifying motivational processes that partly explain the relationships between student-perceived teaching for meaning and competence support and intrinsic motivation and effort in mathematics.

Personality Assessment: A Competency-Capability Perspective.

Kaslow, Nadine J; Finklea, J Tyler; Chan, Ginny

2018-01-01

This article begins by reviewing the proficiency of personality assessment in the context of the competencies movement, which has dominated health service psychology in recent years. It examines the value of including a capability framework for advancing this proficiency and enhancing the quality of personality assessments, including Therapeutic Assessment (Finn & Tonsager, 1997 ), that include a personality assessment component. This hybrid competency-capability framework is used to set the stage for the conduct of personality assessments in a variety of contexts and for the optimal training of personality assessment. Future directions are offered in terms of ways psychologists can strengthen their social contract with the public and offer a broader array of personality assessments in more diverse contexts and by individuals who are both competent and capable.

Reverse-engineering flow-cytometry gating strategies for phenotypic labelling and high-performance cell sorting.

Recent flow and mass cytometers generate datasets of dimensions 20 to 40 and a million single cells. From these, many tools facilitate the discovery of new cell populations associated with diseases or physiology. These new cell populations require the identification of new gating strategies, but gating strategies become exponentially more difficult to optimize when dimensionality increases. To facilitate this step, we developed Hypergate, an algorithm which given a cell population of interest identifies a gating strategy optimized for high yield and purity. Hypergate achieves higher yield and purity than human experts, Support Vector Machines and Random-Forests on public datasets. We use it to revisit some established gating strategies for the identification of innate lymphoid cells, which identifies concise and efficient strategies that allow gating these cells with fewer parameters but higher yield and purity than the current standards. For phenotypic description, Hypergate's outputs are consistent with fields' knowledge and sparser than those from a competing method. Hypergate is implemented in R and available on CRAN.

Predicting optimal transmission investment in malaria parasites

PubMed Central

Greischar, Megan A.; Mideo, Nicole; Read, Andrew F.; Bjørnstad, Ottar N.

2016-01-01

In vertebrate hosts, malaria parasites face a tradeoff between replicating and the production of transmission stages that can be passed onto mosquitoes. This tradeoff is analogous to growth-reproduction tradeoffs in multicellular organisms. We use a mathematical model tailored to the life cycle and dynamics of malaria parasites to identify allocation strategies that maximize cumulative transmission potential to mosquitoes. We show that plastic strategies can substantially outperform fixed allocation because parasites can achieve greater fitness by investing in proliferation early and delaying the production of transmission stages. Parasites should further benefit from restraining transmission investment later in infection, because such a strategy can help maintain parasite numbers in the face of resource depletion. Early allocation decisions are predicted to have the greatest impact on parasite fitness. If the immune response saturates as parasite numbers increase, parasites should benefit from even longer delays prior to transmission investment. The presence of a competing strain selects for consistently lower levels of transmission investment and dramatically increased exploitation of the red blood cell resource. While we provide a detailed analysis of tradeoffs pertaining to malaria life history, our approach for identifying optimal plastic allocation strategies may be broadly applicable. PMID:27271841

The implementation of plan of the day selection for patients receiving radiotherapy (RT) for bladder cancer requires efficient and confident decision-making. This article describes the development of a training programme and maintenance of competency. Cone beam CT (CBCT) images acquired on patients receiving RT for bladder cancer were assessed to establish baseline competency and training needs. A training programme was implemented, and observers were asked to select planning target volumes (PTVs) on two groups of 20 patients' images. After clinical implementation, the PTVs chosen were reviewed offline, and an audit performed after 3 years. A mean of 73% (range, 53-93%) concordance rate was achieved prior to training. Subsequent to training, the mean score decreased to 66% (Round 1), then increased to 76% (Round 2). Six radiographers and two clinicians successfully completed the training programme. An independent observer reviewed the images offline after clinical implementation, and a 91% (126/139) concordance rate was achieved. During the audit, 125 CBCT images from 13 patients were reviewed by a single observer and concordance was 92%. Radiographer-led selection of plan of the day was implemented successfully with the use of a training programme and continual assessment. Quality has been maintained over a period of 3 years. The training programme was successful in achieving and maintaining competency for a plan of the day technique.

A Pareto frontier intersection-based approach for efficient multiobjective optimization of competing concept alternatives

NASA Astrophysics Data System (ADS)

Rousis, Damon A.

The expected growth of civil aviation over the next twenty years places significant emphasis on revolutionary technology development aimed at mitigating the environmental impact of commercial aircraft. As the number of technology alternatives grows along with model complexity, current methods for Pareto finding and multiobjective optimization quickly become computationally infeasible. Coupled with the large uncertainty in the early stages of design, optimal designs are sought while avoiding the computational burden of excessive function calls when a single design change or technology assumption could alter the results. This motivates the need for a robust and efficient evaluation methodology for quantitative assessment of competing concepts. This research presents a novel approach that combines Bayesian adaptive sampling with surrogate-based optimization to efficiently place designs near Pareto frontier intersections of competing concepts. Efficiency is increased over sequential multiobjective optimization by focusing computational resources specifically on the location in the design space where optimality shifts between concepts. At the intersection of Pareto frontiers, the selection decisions are most sensitive to preferences place on the objectives, and small perturbations can lead to vastly different final designs. These concepts are incorporated into an evaluation methodology that ultimately reduces the number of failed cases, infeasible designs, and Pareto dominated solutions across all concepts. A set of algebraic samples along with a truss design problem are presented as canonical examples for the proposed approach. The methodology is applied to the design of ultra-high bypass ratio turbofans to guide NASA's technology development efforts for future aircraft. Geared-drive and variable geometry bypass nozzle concepts are explored as enablers for increased bypass ratio and potential alternatives over traditional configurations. The method is shown to improve sampling efficiency and provide clusters of feasible designs that motivate a shift towards revolutionary technologies that reduce fuel burn, emissions, and noise on future aircraft.

Competency to consent to research: a psychiatric overview.

PubMed

Appelbaum, P S; Roth, L H

1982-08-01

The requirement that a subject be competent as a condition of valid consent to participate in research has been accepted by most students of legal and ethical problems of human experimentation. "Competency," however, has lacked a clear and generally agreed on standard. There are four commonly used standards for competency: evidencing a choice in regard to research participation, factual understanding of the issues, rational manipulation of information, and appreciation of the nature of the situation. These standards can be arranged hierarchically such that each represents a stricter test of competency. The decision as to how rigorous a standard for competency is desirable cannot be made on psychiatric grounds. It requires consideration of the policy goals on hopes to attain. Empirical research helps demonstrate the consequences of choosing a particular standard but cannot replace the need for achieving consensus on policy goals.

Implicit motives and basic need satisfaction in extreme endurance sports.

Previous research has shown that the effects of basic psychological needs on the flow experience in sports are moderated by implicit motives. However, so far, only leisure and health-oriented sports have been analyzed. In a pilot study and a main study (N = 29, 93), we tested whether the implicit achievement and affiliation motives interact with the need for competence and the need for social relatedness satisfaction, respectively, to predict flow experience and well-being in extreme endurance athletes. Results showed that highly achievement-motivated individuals benefited more from the need for competence satisfaction in terms of flow than individuals with a low achievement motive did. In addition, highly affiliation-motivated individuals whose need for social relatedness is satisfied reported higher positive affect and lower exercise addiction scores than athletes with a low motive. We discuss the differential effects of the interplay between the achievement and affiliation motives and basic needs on different outcome variables.

Competencies for public health and interprofessional education in accreditation standards of complementary and alternative medicine disciplines.

PubMed

Brett, Jennifer; Brimhall, Joseph; Healey, Dale; Pfeifer, Joseph; Prenguber, Marcia

2013-01-01

This review examines the educational accreditation standards of four licensed complementary and alternative medicine (CAM) disciplines (naturopathic medicine, chiropractic health care, acupuncture and oriental medicine, and massage therapy), and identifies public health and other competencies found in those standards that contribute to cooperation and collaboration among the health care professions. These competencies may form a foundation for interprofessional education. The agencies that accredit the educational programs for each of these disciplines are individually recognized by the United States Department (Secretary) of Education. Patients and the public are served when healthcare practitioners collaborate and cooperate. This is facilitated when those practitioners possess competencies that provide them the knowledge and skills to work with practitioners from other fields and disciplines. Educational accreditation standards provide a framework for the delivery of these competencies. Requiring these competencies through accreditation standards ensures that practitioners are trained to optimally function in integrative clinical care settings. © 2013 Elsevier Inc.

State and trait effects on individual differences in children's mathematical development.

2014-11-01

Substantial longitudinal relations between children's early mathematics achievement and their much later mathematics achievement are firmly established. These findings are seemingly at odds with studies showing that early educational interventions have diminishing effects on children's mathematics achievement across time. We hypothesized that individual differences in children's later mathematical knowledge are more an indicator of stable, underlying characteristics related to mathematics learning throughout development than of direct effects of early mathematical competency on later mathematical competency. We tested this hypothesis in two longitudinal data sets, by simultaneously modeling effects of latent traits (stable characteristics that influence learning across time) and states (e.g., prior knowledge) on children's mathematics achievement over time. Latent trait effects on children's mathematical development were substantially larger than state effects. Approximately 60% of the variance in trait mathematics achievement was accounted for by commonly used control variables, such as working memory, but residual trait effects remained larger than state effects. Implications for research and practice are discussed. © The Author(s) 2014.

To bee or not to bee, this is the question…: The inborn numerical competence of humans and honeybees.

PubMed

Gross, Hans J

2011-09-01

Human inborn numerical competence means our ability to recognize object numbers precisely under circumstances which do not allow sequential counting. This archaic process has been called "subitizing," from the Latin "subito" = suddenly, immediately, indicating that the objects in question are presented to test persons only for a fraction of a second in order to prevent counting. In contrast, however, sequential counting, an outstanding cultural achievement of mankind, means to count "1, 2, 3, 4, 5, 6, 7, 8…" without a limit. The following essay will explain how the limit of numerical competence, i.e., the recognition of object numbers without counting, has been determined for humans and how this has been achieved for the first time in case of an invertebrate, the honeybee. Finally, a hypothesis explaining the influence of our limited, inborn numerical competence on counting in our times, e.g., in the Russian language, will be presented. Subitizing versus counting by young Down syndrome infants and autistics and the Savant syndrome will be discussed.

This competency framework was developed by a working group of endocrine specialist nurses with the support of the Society for Endocrinology to enhance the clinical care that adults with an endocrine disorder receive. Nurses should be able to demonstrate that they are functioning at an optimal level in order for patients to receive appropriate care. By formulating a competency framework from which an adult endocrine nurse specialist can work, it is envisaged that their development as professional practitioners can be enhanced. This is the second edition of the Competency Framework for Adult Endocrine Nursing. It introduces four new competencies on benign adrenal tumours, hypo- and hyperparathyroidism, osteoporosis and polycystic ovary syndrome. The authors and the Society for Endocrinology welcome constructive feedback on the document, both nationally and internationally, in anticipation that further developments and ideas can be incorporated into future versions. © 2015 Society for Endocrinology.

Vocational school's skill competence assessment is an important phase to complete learning process at vocational school. For vocational school this phase should be designed and implemented not only to measure learning objective target, but also to provide entrepreneurship experience for the graduates. Therefore competence assessment implementation should be done comprehensively in cooperation with Business and Industry Chamber. The implementation of skill competence aspect covering materials, methods, strategies, tools and assessors, need to be designed and optimized with respect to vocational school together with Business and Industry Chamber. This aims to measure the learning objective target and produce improved entrepreneurship graduates. 4M-S strategy in students' skill competence assessment could be done to ensure that the material, method, tool and assessor have been well designed and implemented in both institutions: vocational school and Business and Industry Chamber to improve entrepreneurship graduates.

Important considerations in the management of Graves' disease in pregnant women.

PubMed

Okosieme, Onyebuchi E; Lazarus, John H

2015-01-01

Graves' disease is an autoimmune disorder in which autoantibodies to the thyroid-stimulating hormone receptor cause hyperthyroidism through unregulated stimulation of the thyroid-stimulating hormone receptor. Effective management of Graves' disease in pregnancy must address the competing fetal and maternal priorities of controlling hyperthyroidism in the mother on the one hand, and on the other, minimizing the impact of maternal disease and antithyroid drugs on the well-being of the fetus. Optimal strategies for achieving this intricate balance are currently a source of continued debate among thyroid experts and studies in recent decades are now providing greater clarity into the risk posed to the unborn baby by the combination of biochemical, immunological and pharmacological hazards arising from Graves' disease and its therapy. This review summarizes the current best practice and highlights important considerations and areas of uncertainty in the management of Graves' disease in pregnant women.

Optimization of Norbornadiene Compounds for Solar Thermal Storage by First-Principles Calculations.

2016-07-21

Molecular photoswitches capable of storing solar energy are interesting candidates for future renewable energy applications. Here, using quantum mechanical calculations, we carry out a systematic screening of crucial optical (solar spectrum match) and thermal (storage energy density) properties of 64 such compounds based on the norbornadiene-quadricyclane system. Whereas a substantial number of these molecules reach the theoretical maximum solar power conversion efficiency, this requires a strong red-shift of the absorption spectrum, which causes undesirable absorption by the photoisomer as well as reduced thermal stability. These compounds typically also have a large molecular mass, leading to low storage densities. By contrast, single-substituted systems achieve a good compromise between efficiency and storage density, while avoiding competing absorption by the photo-isomer. This establishes guiding principles for the future development of molecular solar thermal storage systems. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Thin sheets achieve optimal wrapping of liquids

Paulsen, Joseph; Démery, Vincent; Davidovitch, Benny; Santangelo, Christian; Russell, Thomas; Menon, Narayanan

2015-03-01

A liquid drop can wrap itself in a sheet using capillary forces [Py et al., PRL 98, 2007]. However, the efficiency of ``capillary origami'' at covering the surface of a drop is hampered by the mechanical cost of bending the sheet. Thinner sheets deform more readily by forming small-scale wrinkles and stress-focussing patterns, but it is unclear how coverage efficiency competes with mechanical cost as thickness is decreased, and what wrapping shapes will emerge. We place a thin (~ 100 nm) polymer film on a drop whose volume is gradually decreased so that the sheet covers an increasing fraction of its surface. The sheet exhibits a complex sequence of axisymmetric and polygonal partially- and fully- wrapped shapes. Remarkably, the progression appears independent of mechanical properties. The gross shape, which neglects small-scale features, is correctly predicted by a simple geometric approach wherein the exposed area is minimized. Thus, simply using a thin enough sheet results in maximal coverage.

Titanium aluminide alloys have been successfully introduced into civil aircraft engine technology in recent years, and a significant order volume increase is expected in the near future. Due to its beneficial buy-to-fly ratio, investment casting bears the highest potential for cost reduction of all competing production technologies for TiAl-LPTB. However, highest mechanical properties can be achieved by TiAl forging. In view of this, Access e.V. has developed technologies for the production of TiAl investment cast parts and TiAl die cast billets for forging purposes. While these parts meet the highest requirements, establishing series production and further optimizing resource and economic efficiency are present challenges. In order to meet these goals, Access has recently been certified according to aircraft standards, aiming at qualifying parts for production on technology readiness level 6. The present work gives an overview of the phases of development and certification.

Although numerous reports on the synthesis of atom-specific (15)N-labeled nucleosides exist, fast and facile access to the corresponding phosphoramidites for RNA solid-phase synthesis is still lacking. This situation represents a severe bottleneck for NMR spectroscopic investigations on functional RNAs. Here, we present optimized procedures to speed up the synthesis of (15)N(1) adenosine and (15)N(1) guanosine amidites, which are the much needed counterparts of the more straightforward-to-achieve (15)N(3) uridine and (15)N(3) cytidine amidites in order to tap full potential of (1)H/(15)N/(15)N-COSY experiments for directly monitoring individual Watson-Crick base pairs in RNA. Demonstrated for two preQ1 riboswitch systems, we exemplify a versatile concept for individual base-pair labeling in the analysis of conformationally flexible RNAs when competing structures and conformational dynamics are encountered. © 2015 WILEY‐VCH Verlag GmbH & Co.

2018-06-01

Old World cutaneous and mucosal leishmaniasis is a potentially serious disease. Systemic treatment approaches with pentavalent antimonials, liposomal amphotericin B, fluconazole and miltefosine are increasingly used despite the absence of supportive evidence - to date, no prospective clinical trials have been conducted for systemic treatment of these diseases. We performed a literature search to delineate the contemporary evidence for the use of liposomal amphotericin B, and found that although cure rates of 17/20 (85%) were achieved in immune competent patients with Old World cutaneous leishmaniasis and cure rates of 10/13 (77%) for Old World mucosal leishmaniasis due to L. infantum, the available data is highly limited with high variation in total treatment dosages. The presented findings reflect a lack of consensus on the optimal treatment dosage and on the schedule of application. Copyright © 2018 Elsevier B.V. All rights reserved.

Oncolytic virotherapy is an emerging treatment modality that uses replication-competent viruses to destroy cancers. Many naturally occurring viruses have a preferential, although nonexclusive, tropism for tumors and tumor cells. In addition, specific targeting of cancer cells can be achieved at the virus entry level. We optimized retargeting of cell entry by elongating the measles virus attachment protein with designed ankyrin repeat proteins (DARPins), while simultaneously ablating entry through the natural receptors. DARPin-targeted viruses were strongly attenuated in off-target tissue, thereby enhancing safety, but completely eliminated tumor xenografts. Taking advantage of the unique properties of DARPins of being fused without generating folding problems, we generated a virus simultaneous targeting two different tumor markers. The bispecific virus retained the original oncolytic efficacy, while providing proof of concept for a strategy to counteract issues of resistance development. Thus, DARPin-targeting opens new prospects for the development of personalized, targeted therapeutics. PMID:23380817

Interprofessional competence can be defined as knowledge and understanding of their own and the other team members' professional roles, comprehension of communication and teamwork and collaboration in taking care of patients. To evaluate whether students perceived that they had achieved interprofessional competence after participating in clinical teamwork training. Six hundred and sixteen students from four undergraduate educational programs-medicine, nursing, physiotherapy and occupational therapy-participated in an interprofessional course at a clinical education ward. The students filled out pre and post questionnaires (96% response rate). All student groups increased their perceived interprofessional competence. Occupational therapy and medical students had the greatest achievements. All student groups perceived improved knowledge of the other three professions' work (p = 0.000000) and assessed that the course had contributed to the understanding of the importance of communication and teamwork to patient care (effect size 1.0; p = 0.00002). The medical students had the greatest gain (p = 0.00093). All student groups perceived that the clarity of their own professional role had increased significantly (p = 0.00003). Occupational therapy students had the greatest gain (p = 0.000014). Active patient based learning by working together in a real ward context seemed to be an effective means to increase collaborative and professional competence.

Competency-based training model for human resource management and development in public sector

Human Resources (HR) is a very important factor in an organization so that human resources are required to have the ability, skill or competence in order to be able to carry out the vision and mission of the organization. Competence includes a number of attributes attached to the individual which is a combination of knowledge, skills, and behaviors that can be used as a mean to improve performance. Concerned to the demands of human resources that should have the knowledge, skills or abilities, it is necessary to the development of human resources in public organizations. One form of human resource development is Competency-Based Training (CBT). CBT focuses on three issues, namely skills, competencies, and competency standard. There are 5 (five) strategies in the implementation of CBT, namely: organizational scanning, strategic planning, competency profiling, competency gap analysis, and competency development. Finally, through CBT the employees within the organization can reduce or eliminate the differences between existing performance with a potential performance that can improve the knowledge, expertise, and skills that are very supportive in achieving the vision and mission of the organization.

Mothers’ Academic Gender Stereotypes and Education-Related Beliefs About Sons and Daughters in African American Families

2010-01-01

The role of African American mothers’ academic gender stereotype endorsement in shaping achievement-related expectations for and perceptions of their own children was examined. Mothers (N = 334) of 7th and 8th graders completed measures of expectations for their children’s future educational attainment, perceptions of their children’s academic competence, and academic gender stereotypes. Consistent with hypotheses, mothers held less favorable expectations for sons and perceived sons to be less academically competent than daughters. In addition, mothers reported stereotypes favoring girls over boys in academic domains; stereotype endorsement, in turn, was related to mothers’ educational expectations for and beliefs about the academic competence of their own children, even with youths’ actual achievement controlled. Negative stereotypes about the academic abilities of African American boys may create a negative feedback loop, thereby contributing to the maintenance of the gender gap in African Americans’ educational outcomes.

Changes in the Relation Between Competence Beliefs and Achievement in Math Across Elementary School Years.

Weidinger, Anne F; Steinmayr, Ricarda; Spinath, Birgit

2018-03-01

Math competence beliefs and achievement are important outcomes of school-based learning. Previous studies yielded inconsistent results on whether skill development, self-enhancement, or reciprocal effects account for the interplay among them. A development-related change in the direction of their relation in the early school years might explain the inconsistency. To test this, 542 German elementary school students (M = 7.95 years, SD = 0.58) were repeatedly investigated over 24 months from Grade 2 to Grade 4. Math competence beliefs declined and had a growing influence on subsequent math grades. This suggests changes in the dominant direction of the relation from a skill development to a reciprocal effects model during elementary school. Findings are discussed with regard to their theoretical and practical implications. © 2017 The Authors. Child Development © 2017 Society for Research in Child Development, Inc.

Personal and situational predictors of test anxiety of students in post-compulsory education.

Putwain, David W; Woods, Kevin A; Symes, Wendy

2010-03-01

Recent models of evaluation anxiety emphasize the importance of personal knowledge and self-regulatory processes in the development of test anxiety, but do not theorize a route for situational influences. To investigate the relationship between test anxiety and personal knowledge beliefs (achievement goals and perceived academic competence), parental pressure/support, and teachers' achievement goals. One-hundred and seventy five students at a sixth-form college following pre-degree courses in Psychology and Sociology. Self-report data were collected for test anxiety, personal achievement goals, academic self-concept, perceived test competence, teachers' achievement goals, and parental pressure/support. Relationships were examined through correlational and regression analyses. The relationship between test anxiety and personal knowledge beliefs differed for the various components of test anxiety. A mastery-avoidance goal was related to worry and tension, and a performance-approach goal to bodily symptoms. Perceived academic competence was related to worry and tension. Parental pressure was associated with stronger worry and test-irrelevant thinking components directly, and with a stronger bodily symptoms component indirectly through a performance-approach goal. Teachers' performance-avoidance goals were related to worry, tension, and bodily symptoms indirectly through personal performance-avoidance goals, and in the case of bodily symptoms additionally through a performance-approach goal. Findings provide partial support for the self-regulatory model of test anxiety suggesting that additional routes are required to account for the role of parental pressure and teachers' performance-avoidance goals and a re-examination of the relationship between test anxiety and achievement goals.

The adaptation of the educational programmes of European faculties of medicine to the European Higher Education Area guidelines has focused curricula design on competence acquisition. Competencies are defined as the achievements of a predetermined level of efficacy in real-world scenarios. Our objective was to assess whether performance on a common competence evaluation test, the Objective Structured Clinical Examination (OSCE), resulted in different scores for second-year students after a practical medical training course took place in a primary health centre (PHC) or in a hospital. A descriptive study was conducted during the 2010-2014 academic year of the OSCE test scores obtained by all second-year students. Faculty of Medicine at the University of Lleida (Catalonia, Spain). We performed a correlation analysis between students who completed their practical medical training at the PHC and hospitals utilising Student's t-test for comparison of means. 423 students who completed internships at the PHC and at hospitals obtained OSCE mean scores of 7.32 (SD; IC) (0.82; 7.18-7.47) points and 7.17 (0.83; 6.07-7.26) points, respectively (p=0.07). Second-year medical students acquired similar competency levels in the two analysed training scenarios. The two areas both serve their teaching purpose. Copyright © 2014 Elsevier España, S.L.U.

Despite the availability of effective tetanus prevention strategies, as of 2016, Maternal and Neonatal Tetanus Elimination (MNTE) has not yet been achieved in 18 countries globally. In this paper, we review the status of MNTE in the World Health Organization African Region (AFR),and provide recommendations for achieving and maintaining MNTE in AFR. As of November 2016, 37 (79%) AFR countries have achieved MNTE, with 10 (21%) countries remaining. DTP3 coverage increased from 52% in 2000 to 76% in 2015. In 2015, coverage with at least 2 doses of tetanus containing vaccine (TT2+) and proportion of newborns protected at birth (PAB) were 69% and 77%, compared with 44% and 62% in 2000, respectively. Since 1999, over 79 million women of reproductive age (WRA) have been vaccinated with TT2+ through supplementary immunization activities (SIAs). Despite the progress, only 54% of births were attended by skilled birth attendants (SBAs), 5 (11%) countries provided the 3 WHO-recommended booster doses to both sexes, and about 5.5 million WRA still need to be reached with SIAs. Coverage disparities still exist between countries that have achieved MNTE and those that have not. In 2015, coverage with DTP3 and PAB were higher in MNTE countries compared with those yet to achieve MNTE: 84% vs. 68% and 86% vs. 69%, respectively. Challenges to achieving MNTE in the remaining AFR countries include weak health systems, competing priorities, insufficient funding, insecurity, and sub-optimal neonatal tetanus (NT) surveillance. To achieve and maintain MNTE in AFR, increasing SBAs and tetanus vaccination coverage, integrating tetanus vaccination with other opportunities (e.g., polio and measles campaigns, mother and child health days), and providing appropriately spaced booster doses are needed. Strengthening NT surveillance and conducting serosurveys would ensure appropriate targeting of MNTE activities and high-quality information for validating the achievement and maintenance of elimination.

Surges in demand for professional mental health services occasioned by disasters represent a major public health challenge. To build response capacity, numerous psychological first aid (PFA) training models for professional and lay audiences have been developed that, although often concurring on broad intervention aims, have not systematically addressed pedagogical elements necessary for optimal learning or teaching. We describe a competency-based model of PFA training developed under the auspices of the Centers for Disease Control and Prevention and the Association of Schools of Public Health. We explain the approach used for developing and refining the competency set and summarize the observable knowledge, skills, and attitudes underlying the 6 core competency domains. We discuss the strategies for model dissemination, validation, and adoption in professional and lay communities.

2015-08-01

Basic Life Support (BLS) is a life-saving and fundamental skill in resuscitation. However, studies have reported limitations in BLS training outcomes for both health professional and lay populations, and noted the resource and time-intensive nature of traditional training approaches. This exploratory study evaluated the effectiveness of an interactive CD-based BLS training programme that included unsupervised manikin practice compared with a traditional instructor-led BLS training programme involving demonstration and supervised practice. A quasi-experimental post-test with follow-up design was used. The sample was comprised of two cohorts: Novice second-year undergraduate Nursing students (n=187) and Practising Nurses (n=107) in their first year of hospital employment. BLS skill outcomes were assessed at one week and again at eight weeks post training. No statistically significant differences were found between the CD and traditional instructor-led BLS training methods in BLS skills of Novice and Practising Nurses at one week and eight weeks post training. However, there was a decrement in skill between one week and eight weeks post-training across both groups and an overall low level of competence. The failure to find a difference between the CD-based BLS programme with unsupervised manikin practice and a resource-intensive traditional instructor-led BLS training programme may indicate equivalence of the programmes or, even study design limitations. It is concerning that competence displayed by trainees from both groups was less than optimal and suggests the need for renewed efforts to develop and evaluate BLS training programmes which can achieve high rates of competence with acceptable skill retention over time.

Developing criterion-based competencies for tele-intensive care unit.

PubMed

Schleifer, Sarah Joy; Carroll, Karen; Moseley, Marthe J

2014-01-01

Over the last 5 years, telemedicine has developed nursing roles that differ from traditional bedside care. In the midst of this transition, current competency development models focused on task completion may not be the most effective form of proficiency validation. The procedure of competency creation for the role of tele-intensive care unit registered nurse requires a thoughtful process using stakeholders from institutional leadership to frontline staff. The process must include stakeholder approval to ensure appropriate buy-in and follow-through on the agreed-upon criteria. This can be achieved using a standardized method of concept stimulation related to the behaviors, not a memorized list of tasks, expected of a telemedicine registered nurse. This process serves as the foundation for the development of criterion-based competency statements that then allows for clearer expectations. Continually reviewing the written competencies, ensuring current applicability, and revising as needed are necessities for maintaining competence and, therefore, patient safety.

Acquisition of Competencies by Medical Students in Neurological Emergency Simulation Environments Using High Fidelity Patient Simulators.

Sánchez-Ledesma, M J; Juanes, J A; Sáncho, C; Alonso-Sardón, M; Gonçalves, J

2016-06-01

The training of medical students demands practice of skills in scenarios as close as possible to real ones that on one hand ensure acquisition of competencies, and on the other, avoid putting patients at risk. This study shows the practicality of using high definition mannequins (SimMan 3G) in scenarios of first attention in neurological emergencies so that medical students at the Faculty of Medicine of the University of Salamanca could acquire specific and transversal competencies. The repetition of activities in simulation environments significantly facilitates the acquisition of competencies by groups of students (p < 00.5). The greatest achievements refer to skills whereas the competencies that demand greater integration of knowledge seem to need more time or new sessions. This is what happens with the competencies related to the initial diagnosis, the requesting of tests and therapeutic approaches, which demand greater theoretical knowledge.

The core competencies for a discovery operation are the expertise and systems that give the organization an advantage over its competition. Successful outsourcing ventures result in cost reduction, increased operation efficiency and optimization of resource allocation. While there are pitfalls to outsourcing, including poor partner selection and inadequate implementation, outsourcing can be a powerful tool for enhancing drug discovery operations.

Teacher Research Experiences: What We Have Learned and What We Need to Know

Scowcroft, G. A.; Knowlton, C. W.

2006-12-01

The immersion of teachers in scientific research is an effective model for science teacher professional development that builds the capacity of teachers to engage students in scientific inquiry. Most science teachers have had little opportunity to "practice" science. Yet national and state science education standards expect teachers to provide these kinds of experiences for their students. Through the renewal and enhancement that a teacher research experience (TRE) offers, teachers become more capable and motivated to challenge their classes through inquiry-based activities. Although TREs are believed to be successful, there is little published research on their impacts to teaching practice and student science competencies. Research shows that teacher expertise can account for approximately 40 percent of the variance in student learning in reading and mathematics achievement more than any other single factor including student background. Other studies show a similar correlation between teacher expertise and student achievement across the subject areas. There is a critical need for empirical research on the impacts of TREs on science education. Future research could guide funding agencies in setting priorities for the professional development of science teachers as it fine tunes the TRE model to achieve the maximum impact. This presentation will review some of the available literature on TREs and accepted best practices. It will also point to future directions that the TRE community can take to optimize these worthwhile opportunities for teachers.

Repeated testing improves achievement in a blended learning approach for risk competence training of medical students: results of a randomized controlled trial.

PubMed

Spreckelsen, C; Juenger, J

2017-09-26

Adequate estimation and communication of risks is a critical competence of physicians. Due to an evident lack of these competences, effective training addressing risk competence during medical education is needed. Test-enhanced learning has been shown to produce marked effects on achievements. This study aimed to investigate the effect of repeated tests implemented on top of a blended learning program for risk competence. We introduced a blended-learning curriculum for risk estimation and risk communication based on a set of operationalized learning objectives, which was integrated into a mandatory course "Evidence-based Medicine" for third-year students. A randomized controlled trial addressed the effect of repeated testing on achievement as measured by the students' pre- and post-training score (nine multiple-choice items). Basic numeracy and statistical literacy were assessed at baseline. Analysis relied on descriptive statistics (histograms, box plots, scatter plots, and summary of descriptive measures), bootstrapped confidence intervals, analysis of covariance (ANCOVA), and effect sizes (Cohen's d, r) based on adjusted means and standard deviations. All of the 114 students enrolled in the course consented to take part in the study and were assigned to either the intervention or control group (both: n = 57) by balanced randomization. Five participants dropped out due to non-compliance (control: 4, intervention: 1). Both groups profited considerably from the program in general (Cohen's d for overall pre vs. post scores: 2.61). Repeated testing yielded an additional positive effect: while the covariate (baseline score) exhibits no relation to the post-intervention score, F(1, 106) = 2.88, p > .05, there was a significant effect of the intervention (repeated tests scenario) on learning achievement, F(1106) = 12.72, p < .05, d = .94, r = .42 (95% CI: [.26, .57]). However, in the subgroup of participants with a high initial numeracy score no similar effect could be observed. Dedicated training can improve relevant components of risk competence of medical students. An already promising overall effect of the blended learning approach can be improved significantly by implementing a test-enhanced learning design, namely repeated testing. As students with a high initial numeracy score did not profit equally from repeated testing, target-group specific opt-out may be offered.

Commentary on a framework for multicultural education

PubMed Central

Hammerich, Karin F.

2014-01-01

Today’s changing demographics require that multicultural factors be considered in the delivery of quality patient-centred health care in chiropractic. Yet minimal training in cultural competency in chiropractic education leaves graduates ill-equipped to treat a diverse population. This commentary examines cultural competency training in current literature, demonstrates frameworks for curriculum integration, and suggests how cultural competency might be included in a chiropractic college curriculum. A database search yielded little evidence that cultural competency is integrated into curricula of chiropractic schools. Some journal articles note that promoting multicultural education and cultural sensitivity is an important goal. However, they provide no mechanisms as to how this can be achieved within training programs. Thus, although an undeniable need exists for all healthcare practitioners to develop cultural competency in the face of an increasingly diverse population, cultural competency education has not kept pace. Chiropractic schools must review their curricula to develop the cultural competencies of their graduates and a basic framework is suggested. PMID:25202156

To realize learning quality in Vocational Secondary School, and to achieve educational goal, teacher competence is needed. The application of ICT Literacy in vocational secondary school is intended to upgrade teachers’ knowledge, skill and competence in ICT. This paper is aimed to describe the process of teachers’ competence adaptation to ICT integrity in learning in Vocational Secondary School. This study use descriptive method with literature study and documentation technique. The source in this study is research journal and research report book. The study result showed that teachers lack of self-confident in using ICT, and gender factor influence ICT integration in which the level of ICT literacy in male is higher than female. The group of young teachers aged 21-40 have higher level of ICT literacy compared with the older group. Demographic factor in ICT literacy competence are gender, education level and age. This study suggest that teachers enhance the ability in ICT literacy competence, increase their knowledge and knowledge creation in each aspect of ICT literacy competence.

Competing Air Quality and Water Conservation Co-benefits from Power Sector Decarbonization

Peng, W.; Wagner, F.; Mauzerall, D. L.; Ramana, M. V.; Zhai, H.; Small, M.; Zhang, X.; Dalin, C.

Decarbonizing the power sector can reduce fossil-based generation and associated air pollution and water use. However, power sector configurations that prioritize air quality benefits can be different from those that maximize water conservation benefits. Despite extensive work to optimize the generation mix under an air pollution or water constraint, little research has examined electricity transmission networks and the choice of which fossil fuel units to displace in order to achieve both environmental objectives simultaneously. When air pollution and water stress occur in different regions, the optimal transmission and displacement decisions still depend on priorities placed on air quality and water conservation benefits even if low-carbon generation planning is fixed. Here we use China as a test case, and develop a new optimization framework to study transmission and displacement decisions and the resulting air quality and water use impacts for six power sector decarbonization scenarios in 2030 ( 50% of national generation is low carbon). We fix low-carbon generation in each scenario (e.g. type, location, quantity) and vary technology choices and deployment patterns across scenarios. The objective is to minimize the total physical costs (transmission costs and coal power generation costs) and the estimated environmental costs. Environmental costs are estimated by multiplying effective air pollutant emissions (EMeff, emissions weighted by population density) and effective water use (Weff, water use weighted by a local water stress index) by their unit economic values, Vem and Vw. We are hence able to examine the effect of varying policy priorities by imposing different combinations of Vem and Vw. In all six scenarios, we find that increasing the priority on air quality co-benefits (higher Vem) reduces air pollution impacts (lower EMeff) at the expense of lower water conservation (higher Weff); and vice versa. Such results can largely be explained by differences in optimal transmission decisions due to different locations of air pollution and water stress in China (severe in the east and north respectively). To achieve both co-benefits simultaneously, it is therefore critical to coordinate policies that reduce air pollution (pollution tax) and water use (water pricing) with power sector planning.

A framework for using ant colony optimization to schedule environmental flow management alternatives for rivers, wetlands, and floodplains

NASA Astrophysics Data System (ADS)

Szemis, J. M.; Maier, H. R.; Dandy, G. C.

2012-08-01

Rivers, wetlands, and floodplains are in need of management as they have been altered from natural conditions and are at risk of vanishing because of river development. One method to mitigate these impacts involves the scheduling of environmental flow management alternatives (EFMA); however, this is a complex task as there are generally a large number of ecological assets (e.g., wetlands) that need to be considered, each with species with competing flow requirements. Hence, this problem evolves into an optimization problem to maximize an ecological benefit within constraints imposed by human needs and the physical layout of the system. This paper presents a novel optimization framework which uses ant colony optimization to enable optimal scheduling of EFMAs, given constraints on the environmental water that is available. This optimization algorithm is selected because, unlike other currently popular algorithms, it is able to account for all aspects of the problem. The approach is validated by comparing it to a heuristic approach, and its utility is demonstrated using a case study based on the Murray River in South Australia to investigate (1) the trade-off between plant recruitment (i.e., promoting germination) and maintenance (i.e., maintaining habitat) flow requirements, (2) the trade-off between flora and fauna flow requirements, and (3) a hydrograph inversion case. The results demonstrate the usefulness and flexibility of the proposed framework as it is able to determine EFMA schedules that provide optimal or near-optimal trade-offs between the competing needs of species under a range of operating conditions and valuable insight for managers.

The purpose of this study is to investigate the learning curve for colonoscopic polypectomy (CP) by trainee endoscopists. The amount of training required to achieve technical competence for CP is uncertain. The CP times and en bloc resection rates of three experienced colonoscopists were obtained from 240 procedures. These data were compared to those of three gastroenterology trainees who performed 750 CP procedures. A trainee procedure was deemed to be a success if en bloc resection was obtained and the CP time was within twice the median CP time of the experienced colonoscopists. Trainees were deemed to be technically competent when they achieved a CP success rate of greater than or equal to 80%. The median CP times and en bloc resection rates for the experienced colonoscopists and trainees were 79 s (range, 20-301 s) and 99.6% (239/240), and 118 s (range, 36-1051 s) and 95.6% (717/750), respectively. The trainee success rate of CP was 72% (540/750). The success rate of the procedure was associated with increased trainee experience (p = 0.003) and reached 80% after 250 procedures. The CP time significantly decreased (p < 0.001) and en bloc resection rate significantly increased (p = 0.011) as trainee experience accumulated. The level of experience was an independent predictor for successful CP. The achievement of technical competence with CP was associated with an accumulation of approximately 250 procedures. These findings suggest that dedicated education and training programs for CP are warranted.

A cross-sectional study of mathematics achievement, estimation skills, and academic self-perception in students of varying ability.

PubMed

Montague, Marjorie; van Garderen, Delinda

2003-01-01

This study investigated students' mathematics achievement, estimation ability, use of estimation strategies, and academic self-perception. Students with learning disabilities (LD), average achievers, and intellectually gifted students (N = 135) in fourth, sixth, and eighth grade participated in the study. They were assessed to determine their mathematics achievement, ability to estimate discrete quantities, knowledge and use of estimation strategies, and perception of academic competence. The results indicated that the students with LD performed significantly lower than their peers on the math achievement measures, as expected, but viewed themselves to be as academically competent as the average achievers did. Students with LD and average achievers scored significantly lower than gifted students on all estimation measures, but they differed significantly from one another only on the estimation strategy use measure. Interestingly, even gifted students did not seem to have a well-developed understanding of estimation and, like the other students, did poorly on the first estimation measure. The accuracy of their estimates seemed to improve, however, when students were asked open-ended questions about the strategies they used to arrive at their estimates. Although students with LD did not differ from average achievers in their estimation accuracy, they used significantly fewer effective estimation strategies. Implications for instruction are discussed.

Confronting and resolving competing values behind conservation objectives.

Diverse motivations for preserving nature both inspire and hinder its conservation. Optimal conservation strategies may differ radically depending on the objective. For example, creating nature reserves may prevent extinctions through protecting severely threatened species, whereas incentivizing farmland hedgerows may benefit people through bolstering pest-eating or pollinating species. Win-win interventions that satisfy multiple objectives are alluring, but can also be elusive. To achieve better outcomes, we developed and implemented a practical typology of nature conservation framed around seven common conservation objectives. Using an intensively studied bird assemblage in southern Costa Rica as a case study, we applied the typology in the context of biodiversity's most pervasive threat: habitat conversion. We found that rural habitats in a varied tropical landscape, comprising small farms, villages, forest fragments, and forest reserves, provided biodiversity-driven processes that benefit people, such as pollination, seed dispersal, and pest consumption. However, species valued for their rarity, endemism, and evolutionary distinctness declined in farmland. Conserving tropical forest on farmland increased species that international tourists value, but not species discussed in Costa Rican newspapers. Despite these observed trade-offs, our analyses also revealed promising synergies. For example, we found that maintaining forest cover surrounding farms in our study region would likely enhance most conservation objectives at minimal expense to others. Overall, our typology provides a framework for resolving the competing objectives of modern conservation.

However, species valued for their rarity, endemism, and evolutionary distinctness declined in farmland. Conserving tropical forest on farmland increased species that international tourists value, but not species discussed in Costa Rican newspapers. Despite these observed trade-offs, our analyses also revealed promising synergies. For example, we found that maintaining forest cover surrounding farms in our study region would likely enhance most conservation objectives at minimal expense to others. Overall, our typology provides a framework for resolving the competing objectives of modern conservation. PMID:26283400

Automated global structure extraction for effective local building block processing in XCS.

Learning Classifier Systems (LCSs), such as the accuracy-based XCS, evolve distributed problem solutions represented by a population of rules. During evolution, features are specialized, propagated, and recombined to provide increasingly accurate subsolutions. Recently, it was shown that, as in conventional genetic algorithms (GAs), some problems require efficient processing of subsets of features to find problem solutions efficiently. In such problems, standard variation operators of genetic and evolutionary algorithms used in LCSs suffer from potential disruption of groups of interacting features, resulting in poor performance. This paper introduces efficient crossover operators to XCS by incorporating techniques derived from competent GAs: the extended compact GA (ECGA) and the Bayesian optimization algorithm (BOA). Instead of simple crossover operators such as uniform crossover or one-point crossover, ECGA or BOA-derived mechanisms are used to build a probabilistic model of the global population and to generate offspring classifiers locally using the model. Several offspring generation variations are introduced and evaluated. The results show that it is possible to achieve performance similar to runs with an informed crossover operator that is specifically designed to yield ideal problem-dependent exploration, exploiting provided problem structure information. Thus, we create the first competent LCSs, XCS/ECGA and XCS/BOA, that detect dependency structures online and propagate corresponding lower-level dependency structures effectively without any information about these structures given in advance.

The influence of optimism and pessimism on student achievement in mathematics

NASA Astrophysics Data System (ADS)

Yates, Shirley M.

2002-11-01

Students' causal attributions are not only fundamental motivational variables but are also critical motivators of their persistence in learning. Optimism, pessimism, and achievement in mathematics were measured in a sample of primary and lower secondary students on two occasions. Although achievement in mathematics was most strongly related to prior achievement and grade level, optimism and pessimism were significant factors. In particular, students with a more generally pessimistic outlook on life had a lower level of achievement in mathematics over time. Gender was not a significant factor in achievement. The implications of these findings are discussed.

A Two-Minute Paper-and-Pencil Test of Symbolic and Nonsymbolic Numerical Magnitude Processing Explains Variability in Primary School Children's Arithmetic Competence

2013-01-01

Recently, there has been a growing emphasis on basic number processing competencies (such as the ability to judge which of two numbers is larger) and their role in predicting individual differences in school-relevant math achievement. Children’s ability to compare both symbolic (e.g. Arabic numerals) and nonsymbolic (e.g. dot arrays) magnitudes has been found to correlate with their math achievement. The available evidence, however, has focused on computerized paradigms, which may not always be suitable for universal, quick application in the classroom. Furthermore, it is currently unclear whether both symbolic and nonsymbolic magnitude comparison are related to children’s performance on tests of arithmetic competence and whether either of these factors relate to arithmetic achievement over and above other factors such as working memory and reading ability. In order to address these outstanding issues, we designed a quick (2 minute) paper-and-pencil tool to assess children’s ability to compare symbolic and nonsymbolic numerical magnitudes and assessed the degree to which performance on this measure explains individual differences in achievement. Children were required to cross out the larger of two, single-digit numerical magnitudes under time constraints. Results from a group of 160 children from grades 1–3 revealed that both symbolic and nonsymbolic number comparison accuracy were related to individual differences in arithmetic achievement. However, only symbolic number comparison performance accounted for unique variance in arithmetic achievement. The theoretical and practical implications of these findings are discussed which include the use of this measure as a possible tool for identifying students at risk for future difficulties in mathematics.

2013-01-01

The aim of this study was to determine whether dietitians in South Africa are competent to meet the requirements of working in a health care setting during a compulsory one-year community service (CS) program immediately after receiving their degree. A national survey was conducted using questionnaires to illicit information from dietitians on their training and competencies. In 2009, data were collected from both community service dietitians (CSDs) participating in community service programs in primary, secondary and tertiary health care centers in all provinces of South Africa, as well as from their provincial managers (nutrition coordinators). Sixteen (100% response) nutrition coordinators and 134 (80% response) dietitians participated in the quantitative survey. The majority of the CSDs reported that, overall, their academic training had prepared them for most aspects of nutrition service delivery. However, some recommended that academic programs include more training on community-based nutrition programs and in delivering optimal services to under-resourced communities as they believed that their competencies in these two areas were weakest. Furthermore, many CSDs were required to establish dietetics departments where none had previously existed; consequently, their capacity in management and administration needed improvement. In conclusion, academic training institutions should align their programs to the transformation of the health sector in South Africa by ensuring that dietitians are empowered to provide optimal public health nutrition services in under-resourced communities.

Competence, competency-based education, and undergraduate dental education: a discussion paper.

PubMed

Chuenjitwongsa, S; Oliver, R G; Bullock, A D

2018-02-01

The aim of undergraduate dental education is to provide competent dentists to serve societal needs and improve population oral healthcare. Competency-based education has influenced the development of dental education for decades but this term is problematic. This article explores components of competency-based undergraduate health professional education in order to help the dental profession have a better understanding of the context and purposes of undergraduate dental education. This is a discussion paper based on a wide reading of the literature on the education of health professionals with a specific focus on competency-based undergraduate education. Competence comprises an integration of knowledge, skills and attitudes indicating a capability to perform professional tasks safely and ethically. The process of becoming a competent practitioner is complex. Four characteristics of competency-based education are: curriculum components and content shaped by societal needs; focused on student-centred learning; learning achievement; and limited attention to time-based training and numerical targets. Alongside a competency-based approach, undergraduate dental education can be influenced by institutional features and external factors but these receive little consideration in the literature. Understanding competence, competency-based education, and institutional and external factors will help to improve educational quality, define roles and professional development for the dental educator, and inform further research. © 2016 John Wiley & Sons A/S.

A core competency model for family planning public health nurses has been developed, using a three stage Delphi Method with an expert panel of 40 family planning senior administrators, community/public health nursing faculty and seasoned family planning public health nurses. The initial survey was developed from the 2011 Title X Family Planning program priorities. The 32-item survey was distributed electronically via SurveyMonkey(®). Panelist attrition was low, and participation robust resulting in the final 28-item model, suggesting that the Delphi Method was a successful technique through which to achieve consensus. Competencies with at least 75% consensus were included in the model and those competencies were primarily related to education/counseling and administration of medications and contraceptives. The competencies identified have implications for education/training, certification and workplace performance. © 2014 Wiley Periodicals, Inc.

Sources of Individual Differences in Emerging Competence With Numeration Understanding Versus Multidigit Calculation Skill

2014-01-01

This study investigated contributions of general cognitive abilities and foundational mathematical competencies to numeration understanding (i.e., base-10 structure) versus multidigit calculation skill. Children (n = 394, M = 6.5 years) were assessed on general cognitive abilities and foundational numerical competencies at start of 1st grade; on the same numerical competencies, multidigit calculation skill, and numeration understanding at end of 2nd grade; and on multidigit calculation skill and numeration understanding at end of 3rd grade. Path-analytic mediation analysis revealed that general cognitive predictors exerted more direct and more substantial effects on numeration understanding than on multidigit calculations. Foundational mathematics competencies contributed to both outcomes, but largely via 2nd-grade mathematics achievement, and results suggest a mutually supportive role between numeration understanding and multidigit calculations.

Parent self-efficacy, outcome expectancies, and behaviors toward cooking and fruits and vegetables mediate children's eating. Eating competence, an intra-individual approach to food-related attitudes and behaviors, is associated with healthful outcomes but has not been studied as a moderator of parent food-related behaviors that mediate healthful eating in 4th grade children. Parents (n = 339; 78% Hispanic, 89% female) of 4th graders who participated in an impact study of the Cooking with Kids curriculum in Santa Fe, NM schools eligible for Supplemental Nutrition Assistance Program Education completed the following surveys: Satter eating competence inventory for low-income (ecSI/LI) (16 items, Likert scale, possible score 0-48); modeling behaviors related to food preparation and fruits/vegetables (11 items, Likert scale, possible score 0-33); self-efficacy/outcome expectancies (SE/OE) (12 items, Likert scale, possible score 12-60); and availability of fruits/vegetables (20 items, possible score 0-20). Higher scores indicate more desired behaviors. The mean ecSI/LI score was 33.6 ± 8.5; 59% were eating competent, i.e., ecSI/LI ≥ 32. Eating-competent parents demonstrated more modeling (16.3 ± 5.0 vs. 14.0 ± 4.3; P < 0.001), greater SE/OE (53.7 ± 10.1 vs. 51.2 ± 8.5; P = 0.03), and greater in-home fruit/vegetable availability (12.7 ± 3.0 vs. 11.9 ± 3.2; P = 0.02). Two clusters of modeling behavior were defined: achievers and strivers. Modeling achievers (34.9 ± 6.9) were more eating competent (P < 0.001) than strivers (30.3 ± 8.9). Eating competence moderated parent food-related behaviors. Measuring eating competence may contribute to understanding parent behavior as a mediator in school-based nutrition interventions.

A Generalized Decision Framework Using Multi-objective Optimization for Water Resources Planning

NASA Astrophysics Data System (ADS)

Basdekas, L.; Stewart, N.; Triana, E.

2013-12-01

Colorado Springs Utilities (CSU) is currently engaged in an Integrated Water Resource Plan (IWRP) to address the complex planning scenarios, across multiple time scales, currently faced by CSU. The modeling framework developed for the IWRP uses a flexible data-centered Decision Support System (DSS) with a MODSIM-based modeling system to represent the operation of the current CSU raw water system coupled with a state-of-the-art multi-objective optimization algorithm. Three basic components are required for the framework, which can be implemented for planning horizons ranging from seasonal to interdecadal. First, a water resources system model is required that is capable of reasonable system simulation to resolve performance metrics at the appropriate temporal and spatial scales of interest. The system model should be an existing simulation model, or one developed during the planning process with stakeholders, so that 'buy-in' has already been achieved. Second, a hydrologic scenario tool(s) capable of generating a range of plausible inflows for the planning period of interest is required. This may include paleo informed or climate change informed sequences. Third, a multi-objective optimization model that can be wrapped around the system simulation model is required. The new generation of multi-objective optimization models do not require parameterization which greatly reduces problem complexity. Bridging the gap between research and practice will be evident as we use a case study from CSU's planning process to demonstrate this framework with specific competing water management objectives. Careful formulation of objective functions, choice of decision variables, and system constraints will be discussed. Rather than treating results as theoretically Pareto optimal in a planning process, we use the powerful multi-objective optimization models as tools to more efficiently and effectively move out of the inferior decision space. The use of this framework will help CSU evaluate tradeoffs in a continually changing world.

2006-01-01

Objectives To create a virtual laboratory system in which experimental science students could learn required skills and competencies while overcoming such challenges as time limitations, high cost of resources, and lack of feedback often encountered in a traditional laboratory setting. Design A blended learning experience that combines traditional practices and e-learning was implemented to teach microbiological methods to pharmacy students. Virtual laboratory modules were used to acquire nonmanual skills such as visual and mental skills for data reading, calculations, interpretation of the results, deployment of an analytical protocol, and reporting results. Assesment Learning achievement was evaluated by questions about microbiology case-based problems. Students' perceptions were obtained by assessment questionnaire. Conclusion By combining different learning scenarios, the acquisition of the necessary but otherwise unreachable competences was achieved. Students achieved similar grades in the modules whose initiation was in the virtual laboratory to the grades they achieved with the modules whose complete or partial initiation took place in the laboratory. The knowledge acquired was satisfactory and the participants valued the experience. PMID:17149449

There is no "i" in teamwork in the patient-centered medical home: defining teamwork competencies for academic practice.

Evidence suggests that teamwork is essential for safe, reliable practice. Creating health care teams able to function effectively in patient-centered medical homes (PCMHs), practices that organize care around the patient and demonstrate achievement of defined quality care standards, remains challenging. Preparing trainees for practice in interprofessional teams is particularly challenging in academic health centers where health professions curricula are largely siloed. Here, the authors review a well-delineated set of teamwork competencies that are important for high-functioning teams and suggest how these competencies might be useful for interprofessional team training and achievement of PCMH standards. The five competencies are (1) team leadership, the ability to coordinate team members' activities, ensure appropriate task distribution, evaluate effectiveness, and inspire high-level performance, (2) mutual performance monitoring, the ability to develop a shared understanding among team members regarding intentions, roles, and responsibilities so as to accurately monitor one another's performance for collective success, (3) backup behavior, the ability to anticipate the needs of other team members and shift responsibilities during times of variable workload, (4) adaptability, the capability of team members to adjust their strategy for completing tasks on the basis of feedback from the work environment, and (5) team orientation, the tendency to prioritize team goals over individual goals, encourage alternative perspectives, and show respect and regard for each team member. Relating each competency to a vignette from an academic primary care clinic, the authors describe potential strategies for improving teamwork learning and applying the teamwork competences to academic PCMH practices.

2015-03-01

To evaluate the effect of an active learning program on competency of senior students. Active learning strategies have been used to help students achieve desired nursing competency, but their effectiveness has not been systematically examined. A descriptive, cross-sectional comparative design was used. Two cohort group comparisons using t-test were made: one in an active learning group and the other in a traditional learning group. A total of 147 senior nursing students near graduation participated in this study: 73 in 2010 and 74 in 2013. The active learning program incorporated high-fidelity simulation, situation-based case studies, standardized patients, audio-video playback, reflective activities and technology such as a SmartPad-based program. The overall scores of the nursing competency in the active group were significantly higher than those in the traditional group. Of five overall subdomains, the scores of the special and general clinical performance competency, critical thinking and human understanding were significantly higher in the active group than in the traditional group. Importance-performance analysis showed that all five subdomains of the active group clustered in the high importance and high performance quadrant, indicating significantly better achievements. In contrast, the students in the traditional group showed scattered patterns in three quadrants, excluding the low importance and low performance quadrants. This pattern indicates that the traditional learning method did not yield the high performance in most important areas. The findings of this study suggest that an active learning strategy is useful for helping undergraduate students to gain competency. © 2014 John Wiley & Sons Ltd.

A comparative study of results of the von Langenbeck and the V-Y pushback palatoplasties.

PubMed

Krause, C J; Tharp, R F; Morris, H L

1976-01-01

The incidence of velopharyngeal competence noted in 267 cleft palate patients following palatoplsty has been reviewed. Comparisons have been drawn with regard to the cleft type and the surgical technique performed. Since there were relatively small numbers of subjects in some categories, differences in age at last examination between the von Langenbeck and V-Y palatoplasty groups, some patients were very young at time of evaluation, and a number of different surgeons at different levels of training and experience performed the surgery, the differences in velopharyngeal competence found should be viewed as trends and this report as preliminary. In general, there was a trend toward smaller percentages of patients attaining acceptable velopharyngeal competence as the severity of the cleft increased. Of those with clefts of the soft palate only 86 per cent achieved competence. Among those patients with clefts of the palate only, 67 per cent achieved competence, whereas only 57 per cent of those with clefts of the lip and palate were able to do so. When comparing all cleft types, the V-Y palatoplasty resulted in a significantly higher percentage of velopharyngeal competence (74 per cent) than did the von Langenbeck method (56 per cent), although the data for the V-Y group are probably less reliable than those for the von Langenbeck group. In the soft palate only category, the results were slightly better with the von Langenbeck technique, though not significantly so. In all other cleft types, the results with the V-Y method were better than those with the von Langenbeck.

Over a 2-year period, the executive committee and other experts in the field convened regularly to identify specific areas in need of future research. Six content areas within emergency diagnostic imaging were identified before the conference and served as the breakout groups on which consensus was achieved: clinical decision rules; use of administrative data; patient-centered outcomes research; training, education, and competency; knowledge translation and barriers to imaging optimization; and comparative effectiveness research in alternatives to traditional computed tomography use. The executive committee invited key stakeholders to assist with the planning and to participate in the consensus conference to generate a multidisciplinary agenda. There were a total of 164 individuals involved in the conference and spanned various specialties, including general emergency medicine, pediatric emergency medicine, radiology, surgery, medical physics, and the decision sciences.

This report describes a multi-disciplinary program to develop a pediatric blood pump, motivated by the critical need to treat infants and young children with congenital and acquired heart diseases. The unique challenges of this patient population require a device with exceptional biocompatibility, miniaturized for implantation up to 6 months. This program implemented a collaborative, prescriptive design process, whereby mathematical models of the governing physics were coupled with numerical optimization to achieve a favorable compromise among several competing design objectives. Computational simulations of fluid dynamics, electromagnetics, and rotordynamics were performed in two stages: first using reduced-order formulations to permit rapid optimization of the key design parameters; followed by rigorous CFD and FEA simulations for calibration, validation, and detailed optimization. Over 20 design configurations were initially considered, leading to three pump topologies, judged on the basis of a multi-component analysis including criteria for anatomic fit, performance, biocompatibility, reliability, and manufacturability. This led to fabrication of a mixed-flow magnetically levitated pump, the PF3, having a displaced volume of 16.6 cc, approximating the size of a AA battery and producing a flow capacity of 0.3-1.5 L/min. Initial in vivo evaluation demonstrated excellent hemocompatibility after 72 days of implantation in an ovine. In summary, combination of prescriptive and heuristic design principles have proven effective in developing a miniature magnetically levitated blood pump with excellent performance and biocompatibility, suitable for integration into chronic circulatory support system for infants and young children; aiming for a clinical trial within 3 years.

2014-12-01

The aim of the article is to investigate whether motor competence and cognitive abilities influence the quality of performance of activities of daily living (ADL) in children with hemiparesis. Patients and A total of 20 children with hemiparesis (age, 6-12 years; 11 congenital, 9 acquired during childhood) were studied. Motor competence was assessed with the Assisting Hand Assessment, cognitive abilities with the German version of the Wechsler Intelligence Scale for Children IV, and the quality of ADL performance with the Assessment of Motor and Process Skills (AMPS). The motor skills scale of the AMPS correlated with motor competence, and the process skills scale of the AMPS correlated with cognitive abilities. The quality of ADL performance is influenced not only by motor competence but also by the cognitive abilities of a hemiparetic child. This suggests that, in addition to motor-oriented training programs, an optimal therapy for hemiparetic children should also consider cognitive approaches.

Gaddy, Melissa R.; Yıldız, Sercan; Unkelbach, Jan; Papp, Dávid

2018-01-01

Spatiotemporal fractionation schemes, that is, treatments delivering different dose distributions in different fractions, can potentially lower treatment side effects without compromising tumor control. This can be achieved by hypofractionating parts of the tumor while delivering approximately uniformly fractionated doses to the surrounding tissue. Plan optimization for such treatments is based on biologically effective dose (BED); however, this leads to computationally challenging nonconvex optimization problems. Optimization methods that are in current use yield only locally optimal solutions, and it has hitherto been unclear whether these plans are close to the global optimum. We present an optimization framework to compute rigorous bounds on the maximum achievable normal tissue BED reduction for spatiotemporal plans. The approach is demonstrated on liver tumors, where the primary goal is to reduce mean liver BED without compromising any other treatment objective. The BED-based treatment plan optimization problems are formulated as quadratically constrained quadratic programming (QCQP) problems. First, a conventional, uniformly fractionated reference plan is computed using convex optimization. Then, a second, nonconvex, QCQP model is solved to local optimality to compute a spatiotemporally fractionated plan that minimizes mean liver BED, subject to the constraints that the plan is no worse than the reference plan with respect to all other planning goals. Finally, we derive a convex relaxation of the second model in the form of a semidefinite programming problem, which provides a rigorous lower bound on the lowest achievable mean liver BED. The method is presented on five cases with distinct geometries. The computed spatiotemporal plans achieve 12-35% mean liver BED reduction over the optimal uniformly fractionated plans. This reduction corresponds to 79-97% of the gap between the mean liver BED of the uniform reference plans and our lower bounds on the lowest achievable mean liver BED. The results indicate that spatiotemporal treatments can achieve substantial reductions in normal tissue dose and BED, and that local optimization techniques provide high-quality plans that are close to realizing the maximum potential normal tissue dose reduction.

International Nursing: Nurse Managers' Leadership and Management Competencies Assessed by Nursing Personnel in a Finnish Hospital.

PubMed

Lehtonen, Mia-Riitta; Roos, Mervi; Kantanen, Kati; Suominen, Tarja

The aim of this research was to describe nurse managers' leadership and management competencies (NMLMC) from the perspective of nursing personnel. Nurse managers are responsible for the management of the largest professional group in social and health care. The assessment of NMLMC is needed because of their powerful influence on organizational effectiveness. An electronic survey was conducted among the nursing personnel (n = 166) of 1 Finnish hospital in spring 2016. Nursing personnel assessed their manager using a NMLMC scale consisting of general and special competences. The data were statistically analyzed. Leadership and management competencies were assessed as being quite good by the nursing personnel. The best-assessed area of general competence was professional competence and credibility and the weakest was service initiation and innovation. The best-assessed area of special competence was substance knowledge and the weakest was research and development. The nursing personnel's assessment of their nurse manger's competencies was associated with the personnel's education level, working experience, and with their knowledge of the manager's education. Conclusion was made that nursing personnel highly value professional competence as part of nursing leadership and management. To achieve more appreciation, nurse managers have to demonstrate their education and competence. They must also work in more open and versatile ways with their nursing personnel.

Assessment of competency in endoscopy: establishing and validating generalizable competency benchmarks for colonoscopy.

Sedlack, Robert E; Coyle, Walter J

The Mayo Colonoscopy Skills Assessment Tool (MCSAT) has previously been used to describe learning curves and competency benchmarks for colonoscopy; however, these data were limited to a single training center. The newer Assessment of Competency in Endoscopy (ACE) tool is a refinement of the MCSAT tool put forth by the Training Committee of the American Society for Gastrointestinal Endoscopy, intended to include additional important quality metrics. The goal of this study is to validate the changes made by updating this tool and establish more generalizable and reliable learning curves and competency benchmarks for colonoscopy by examining a larger national cohort of trainees. In a prospective, multicenter trial, gastroenterology fellows at all stages of training had their core cognitive and motor skills in colonoscopy assessed by staff. Evaluations occurred at set intervals of every 50 procedures throughout the 2013 to 2014 academic year. Skills were graded by using the ACE tool, which uses a 4-point grading scale defining the continuum from novice to competent. Average learning curves for each skill were established at each interval in training and competency benchmarks for each skill were established using the contrasting groups method. Ninety-three gastroenterology fellows at 10 U.S. academic institutions had 1061 colonoscopies assessed by using the ACE tool. Average scores of 3.5 were found to be inclusive of all minimal competency thresholds identified for each core skill. Cecal intubation times of less than 15 minutes and independent cecal intubation rates of 90% were also identified as additional competency thresholds during analysis. The average fellow achieved all cognitive and motor skill endpoints by 250 procedures, with >90% surpassing these thresholds by 300 procedures. Nationally generalizable learning curves for colonoscopy skills in gastroenterology fellows are described. Average ACE scores of 3.5, cecal intubation rates of 90%, and intubation times less than 15 minutes are recommended as minimal competency criteria. On average, it takes 250 procedures to achieve competence in colonoscopy. The thresholds found in this multicenter cohort by using the ACE tool are nearly identical to the previously established MCSAT benchmarks and are consistent with recent gastroenterology training recommendations but far higher than current training requirements in other specialties.

Patil, Nivritti G; Cheng, Stephen W K; Wong, John

2003-08-01

Recent high-profile cases have heightened the need for a formal structure to monitor achievement and maintenance of surgical competence. Logbooks, morbidity and mortality meetings, videos and direct observation of operations using a checklist, motion analysis devices, and virtual reality simulators are effective tools for teaching and evaluating surgical skills. As the operating theater is also a place for training, there must be protocols and guidelines, including mandatory standards for supervision, to ensure that patient care is not compromised. Patients appreciate frank communication and honesty from surgeons regarding their expertise and level of competence. To ensure that surgical competence is maintained and keeps pace with technologic advances, professional registration bodies have been promoting programs for recertification. They evaluate performance in practice, professional standing, and commitment to ongoing education.

Gaps exist in health professional education versus the demands of current practice. Leveraging front-line nurses to teach students exemplary practice in a Dedicated Education Unit (DEU) may narrow this gap. The DEU is an innovative model for experiential learning, capitalizing on the expertise of staff nurses as clinical teachers. This study evaluated the effectiveness of a new academic-practice DEU in facilitating quality and safety competency achievement among students. Six clinical teachers received education in clinical teaching and use of Quality and Safety Education for Nurses (QSEN) competencies to guide acquisition of essential knowledge, skills, and attitudes for continuous health care improvement. Twelve students assigned to the six teachers completed daily logs for the 10-week practicum. Findings suggest that DEU students achieved QSEN competencies through clinical teacher mentoring in interdisciplinary collaboration, using electronic information for best practice and patient teaching, patient/family decision making, quality improvement, and resolution of safety issues.

Value-Based Pricing and Reimbursement in Personalised Healthcare: Introduction to the Basic Health Economics

2017-01-01

‘Value-based’ outcomes, pricing, and reimbursement are widely discussed as health sector reforms these days. In this paper, we discuss their meaning and relationship in the context of personalized healthcare, defined as receipt of care conditional on the results of a biomarker-based diagnostic test. We address the question: “What kinds of pricing and reimbursement models should be applied in personalized healthcare?” The simple answer is that competing innovators and technology adopters should have incentives that promote long-term dynamic efficiency. We argue that—to meet this social objective of optimal innovation in personalized healthcare—payers, as agents of their plan participants, should aim to send clear signals to their suppliers about what they value. We begin by revisiting the concept of value from an economic perspective, and argue that a broader concept of value is needed in the context of personalized healthcare. We discuss the market for personalized healthcare and the interplay between price and reimbursement. We close by emphasizing the potential barrier posed by inflexible or cost-based reimbursement systems, especially for biomarker-based predictive tests, and how these personalized technologies have global public goods characteristics that require global value-based differential pricing to achieve dynamic efficiency in terms of the optimal rate of innovation and adoption.

Climate change is a driving force behind some recent environmental legislation around the world. Greenhouse gas emission reduction targets have been set in many industrialised countries. A change in current practices of almost all greenhouse-emitting industrial sectors is unavoidable, if the set targets is to be achieved. Although, waste disposal contributes around 3% of the total greenhouse gas emissions in Australia (mainly due to fugitive methane emissions from landfills), the carbon credit and trading scheme set to start in 2010 presents significant challenges and opportunities to municipal solid waste practitioners. Technological advances in waste management, if adopted properly, allow themore » municipal solid waste sector to act as carbon sink, hence earning tradable carbon credits. However, due to the complexity of the system and its inherent uncertainties, optimizing it for carbon credits may worsen its performance under other criteria. We use an integrated, stochastic multi-criteria decision-making tool that we developed earlier to analyse the carbon credit potential of Sydney municipal solid waste under eleven possible future strategies. We find that the changing legislative environment is likely to make current practices highly non-optimal and increase pressures for a change of waste management strategy.« less

Predicting optimal transmission investment in malaria parasites.

PubMed

Greischar, Megan A; Mideo, Nicole; Read, Andrew F; Bjørnstad, Ottar N

2016-07-01

In vertebrate hosts, malaria parasites face a tradeoff between replicating and the production of transmission stages that can be passed onto mosquitoes. This tradeoff is analogous to growth-reproduction tradeoffs in multicellular organisms. We use a mathematical model tailored to the life cycle and dynamics of malaria parasites to identify allocation strategies that maximize cumulative transmission potential to mosquitoes. We show that plastic strategies can substantially outperform fixed allocation because parasites can achieve greater fitness by investing in proliferation early and delaying the production of transmission stages. Parasites should further benefit from restraining transmission investment later in infection, because such a strategy can help maintain parasite numbers in the face of resource depletion. Early allocation decisions are predicted to have the greatest impact on parasite fitness. If the immune response saturates as parasite numbers increase, parasites should benefit from even longer delays prior to transmission investment. The presence of a competing strain selects for consistently lower levels of transmission investment and dramatically increased exploitation of the red blood cell resource. While we provide a detailed analysis of tradeoffs pertaining to malaria life history, our approach for identifying optimal plastic allocation strategies may be broadly applicable. © 2016 The Author(s).

To assess the feasibility of Option Grids(®)for facilitating shared decision making (SDM) in simulated clinical consultations and explore clinicians' views on their practicability. We used mixed methods approach to analyze clinical consultations using the Observer OPTION instrument and thematic analysis for follow-up interviews with clinicians. Clinicians achieved high scores on information sharing and low scores on preference elicitation and integration. Four themes were identified: (1) Barriers affect practicability of Option Grids(®); (2) Option Grids(®) facilitate the SDM process; (3) Clinicians are aware of the gaps in their practice of SDM; (4) Training and ongoing feedback on the optimal use of Option Grids(®) are necessary. Use of Option Grids(®) by clinicians with background knowledge in SDM did not facilitate optimal levels of competency on the SDM core concepts of preference elicitation and integration. Future research must evaluate the impact of training on the use of Option Grids(®), and explore how best to help clinicians bridge the gap between knowledge and action. Clinicians proficiently imparting information in simulations struggled to elicit and integrate patient preferences - understanding this gap and developing strategies to close it are the next steps for implementing SDM into clinical practice.

A novel orbiter mission concept for venus with the EnVision proposal

NASA Astrophysics Data System (ADS)

de Oliveira, Marta R. R.; Gil, Paulo J. S.; Ghail, Richard

2018-07-01

In space exploration, planetary orbiter missions are essential to gain insight into planets as a whole, and to help uncover unanswered scientific questions. In particular, the planets closest to the Earth have been a privileged target of the world's leading space agencies. EnVision is a mission proposal designed for Venus and competing for ESA's next launch opportunity with the objective of studying Earth's closest neighbor. The main goal is to study geological and atmospheric processes, namely surface processes, interior dynamics and atmosphere, to determine the reasons behind Venus and Earth's radically different evolution despite the planets' similarities. To achieve these goals, the operational orbit selection is a fundamental element of the mission design process. The design of an orbit around Venus faces specific challenges, such as the impossibility of choosing Sun-synchronous orbits. In this paper, an innovative genetic algorithm optimization was applied to select the optimal orbit based on the parameters with more influence in the mission planning, in particular the mission duration and the coverage of sites of interest on the Venusian surface. The solution obtained is a near-polar circular orbit with an altitude of 259 km that enables the coverage of all priority targets almost two times faster than with the parameters considered before this study.

How scientists develop competence in visual communication

NASA Astrophysics Data System (ADS)

Ostergren, Marilyn

Visuals (maps, charts, diagrams and illustrations) are an important tool for communication in most scientific disciplines, which means that scientists benefit from having strong visual communication skills. This dissertation examines the nature of competence in visual communication and the means by which scientists acquire this competence. This examination takes the form of an extensive multi-disciplinary integrative literature review and a series of interviews with graduate-level science students. The results are presented as a conceptual framework that lays out the components of competence in visual communication, including the communicative goals of science visuals, the characteristics of effective visuals, the skills and knowledge needed to create effective visuals and the learning experiences that promote the acquisition of these forms of skill and knowledge. This conceptual framework can be used to inform pedagogy and thus help graduate students achieve a higher level of competency in this area; it can also be used to identify aspects of acquiring competence in visual communication that need further study.

Cardiac nursing: achieving competent practitioners.

PubMed

Riley, Jillian; Brodie, Lyndell; Shuldham, Caroline

2005-03-01

This paper describes how competency statements were integrated into an academic framework to provide a transparent yet flexible career pathway for the nurse working in acute cardiac care. Nurses are expanding and developing their roles and use wide ranging skills and knowledge to care for patients. Additionally, models of care delivery are changing and patients are cared for in a variety of settings. Where evidence exists, these models demonstrate improvement in the provision and quality of services and contribute to improved quality of life, maximise medication and therapy and reduce waiting times for investigations. However, whilst many studies have demonstrated benefit, translating these results into routine practice requires skilled nurses who are "fit for purpose," and to support this, professional competencies can be used to measure competence in practice whilst informing educational initiatives. This paper outlines the development of competency statements that identify the knowledge and skills required for safe, effective and competent care and direct the cardiac nurse acquire skills and knowledge in a focused and coherent way.

Type 2 diabetes mellitus increases skeletal fragility; however, the contributing mechanisms and optimal treatment strategies remain unclear. We studied the effects of diabetes and insulin therapy on non-enzymatic glycation (NEG), cortical porosity (Ct.Po) and biomechanics of the bone tissue in Zucker Diabetic Fatty (ZDF) rats. Eleven-week old ZDF diabetic and non-diabetic rats were given insulin to achieve glycaemic control or vehicle seven days per week over twelve weeks (insulin dose adapted individually 0.5 international units (IU) at week 1 to 13.0IU at week 12). The right femora were excised, micro-CT scanned, and tested in 3-point bending to measure biomechanics. NEG of the midshaft was determined from bulk fluorescence. Diabetes led to increased NEG (+50.1%, p=0.001) and Ct.Po (+22.9%, p=0.004), as well as to reduced mechanical competence (max. stress: -14.2%, p=0.041, toughness: -29.7%, p=0.016) in the bone tissue. NEG and Ct.Po both correlated positively to serum glucose (NEG: R(2)=0.41, p<0.001, Ct.Po: R(2)=0.34, p=0.003) and HbA1c (NEG: R(2)=0.42, p<0.001, Ct.Po: R(2)=0.28, p=0.008) levels, while NEG correlated negatively with bone biomechanics (elastic modulus: R(2)=0.21, p=0.023, yield stress: R(2)=0.17, p=0.047). Twelve weeks of insulin therapy had no significant effect on NEG or Ct.Po, and was unable to improve the mechanical competence of the bone tissue. A reduction of mechanical competence was observed in the bone tissue of the diabetic rats, which was explained in part by increased collagen NEG. Twelve weeks of insulin therapy did not alter NEG, Ct.Po or bone biomechanics. However, significant correlations between NEG and serum glucose and HbA1c were observed, both of which were reduced with insulin therapy. This suggests that a longer duration of insulin therapy may be required to reduce the NEG of the bone collagen and restore the mechanical competence of diabetic bone. Copyright © 2016 Elsevier Inc.

Volunteers that passed a post-training interview, by demonstrating a basic level of competency in three domains (Self as Navigator, Communication, and Knowledge/Information), were invited to participate as volunteer lay navigators in a three-step intervention with newly diagnosed lung cancer patients at the British Columbia Cancer Agency-Vancouver Island Centre. Of the 27 volunteers who attended a screening interview, 20 were invited to participate in training. From the subset of 20, 13 of these participants achieved competency scores high enough to qualify them to practice as volunteer lay navigators. By incorporating the lessons we have learned from this study, we believe that the lay navigation competency framework serves as a useful model for selecting, training, and supporting competent navigators.

In perceptual decision-making, ideal decision-makers should bias their choices toward alternatives associated with larger rewards, and the extent of the bias should decrease as stimulus sensitivity increases. When responses must be made at different times after stimulus onset, stimulus sensitivity grows with time from zero to a final asymptotic level. Are decision makers able to produce responses that are more biased if they are made soon after stimulus onset, but less biased if they are made after more evidence has been accumulated? If so, how close to optimal can they come in doing this, and how might their performance be achieved mechanistically? We report an experiment in which the payoff for each alternative is indicated before stimulus onset. Processing time is controlled by a “go” cue occurring at different times post stimulus onset, requiring a response within msec. Reward bias does start high when processing time is short and decreases as sensitivity increases, leveling off at a non-zero value. However, the degree of bias is sub-optimal for shorter processing times. We present a mechanistic account of participants' performance within the framework of the leaky competing accumulator model [1], in which accumulators for each alternative accumulate noisy information subject to leakage and mutual inhibition. The leveling off of accuracy is attributed to mutual inhibition between the accumulators, allowing the accumulator that gathers the most evidence early in a trial to suppress the alternative. Three ways reward might affect decision making in this framework are considered. One of the three, in which reward affects the starting point of the evidence accumulation process, is consistent with the qualitative pattern of the observed reward bias effect, while the other two are not. Incorporating this assumption into the leaky competing accumulator model, we are able to provide close quantitative fits to individual participant data. PMID:21390225

Objectives. To conduct a prospective evaluation for effectiveness of an error disclosure assessment tool and video recordings to enhance student learning and metacognitive skills while assessing the IPEC competencies. Design. The instruments for assessing performance (planning, communication, process, and team dynamics) in interprofessional error disclosure were developed. Student self-assessment of performance before and after viewing the recordings of their encounters were obtained. Faculty used a similar instrument to conduct real-time assessments. An instrument to assess achievement of the Interprofessional Education Collaborative (IPEC) core competencies was developed. Qualitative data was reviewed to determine student and faculty perceptions of the simulation. Assessment. The interprofessional simulation training involved a total of 233 students (50 dental, 109 nursing and 74 pharmacy). Use of video recordings made a significant difference in student self-assessment for communication and process categories of error disclosure. No differences in student self-assessments were noted among the different professions. There were differences among the family member affects for planning and communication for both pre-video and post-video data. There were significant differences between student self-assessment and faculty assessment for all paired comparisons, except communication in student post-video self-assessment. Students' perceptions of achievement of the IPEC core competencies were positive. Conclusion. The use of assessment instruments and video recordings may have enhanced students' metacognitive skills for assessing performance in interprofessional error disclosure. The simulation training was effective in enhancing perceptions on achievement of IPEC core competencies. This enhanced assessment process appeared to enhance learning about the skills needed for interprofessional error disclosure.

To design and implement a case study on the cervical cancer screening program in Botswana to teach public and global health competencies to undergraduate nursing students. The case study was developed following a review of the literature on the epidemiology and health policies of cervical cancer in Botswana, and an interview with an obstetrician/gynecologist engaged in both clinical practice and research in Botswana. The case study has been implemented over seven semesters to students enrolled in the Nursing in the Community course at the University of Pennsylvania. Approximately 75-100 students are enrolled each semester. Student's perceptions of epidemiologic skills gained and group functioning. Students responded to an open-ended question about lessons learned and offered suggestions to improve the learning experience. Faculty assessment of student deliverables demonstrated that students achieved the learning objectives and mastered necessary competencies. More than 70% (n = 69) of the students indicated that they acquired relevant skills at greater than a satisfactory level. Generally, students had great experiences working in groups measured across five dimensions: engagement/contribution, creativity/resilience, on task/works independently, social interaction/communication, and preparedness. However, isolated cases of poor group functioning were reported for engagement/contribution, and creativity/resilience. The case study, which has been revised with respect to length, content and group processes, has been valuable in educating undergraduate nursing students in a more engaging way that mimics real life public health nursing scenarios. Students achieved both public and global health competencies through participation in the case study. © 2018 Wiley Periodicals, Inc.

This paper describes the production, purification, and immobilization of l-asparaginase II (ASNase II) in chitosan nanoparticles (CSNPs). ASNase II is an effective antineoplastic agent, used in the acute lymphoblastic leukemia chemotherapy. Cloned ASNase II gene ( ansB) in pAED4 plasmid was transformed into Escherichia coli BL21pLysS (DE3) competent cells and expressed under optimal conditions. The lyophilized enzyme was loaded into CSNPs by ionotropic gelation method. In order to get optimal entrapment efficiency, CSNP preparation, chitosan/tripolyphosphate (CS/TPP) ratio, and protein loading were investigated. ASNase II loading into CSNPs was confirmed by Fourier transform infrared (FTIR) spectroscopy, and morphological observation was carried out by transmission electron microscopy. Three absolute CS/TPP ratios were studied. Entrapment efficiency and loading capacity increased with increasing CS and TPP concentration. The best ratio was applied for obtaining optimal ASNase II-loaded CSNPs with the highest entrapment efficiency. Size, zeta potential, entrapment efficiency, and loading capacity of the optimal ASNase II-CSNPs were 340 ± 12 nm, 21.2 ± 3 mV, 76.2% and 47.6%, respectively. The immobilized enzyme showed an increased in vitro half-life in comparison with the free enzyme. The pH and thermostability of the immobilized enzyme was comparable with the free enzyme. This study leads to a better understanding of how to prepare CSNPs, how to achieve high encapsulation efficiency for a high molecular weight protein, and how to prolong the release of protein from CSNPs. A conceptual understanding of biological responses to ASNase II-loaded CSNPs is needed for the development of novel methods of drug delivery.

The current study aims to explore how the decision-making style of maximizing affects subjective well-being (SWB), which mainly focuses on the confirmation of the mediator role of regret and suppressing role of achievement motivation. A total of 402 Chinese undergraduate students participated in this study, in which they responded to the maximization, regret, and achievement motivation scales and SWB measures. Results suggested that maximizing significantly predicted SWB. Moreover, regret and achievement motivation (hope for success dimension) could completely mediate and suppress this effect. That is, two competing indirect pathways exist between maximizing and SWB. One pathway is through regret. Maximizing typically leads one to regret, which could negatively predict SWB. Alternatively, maximizing could lead to high levels of hope for success, which were positively correlated with SWB. Findings offered a complex method of thinking about the relationship between maximizing and SWB. PMID:29467694

One of the goals of higher professional education is to develop generic student competencies across a variety of disciplines that play a crucial role in education and that provide wider opportunities for graduates in finding good jobs and more chance of promotion. In this article a list of generic competencies developed in Russian universities is compared with a similar list developed by a consortium of Russian and European universities (project TUNING-RUSSIA). Then there is a second comparison with a list of competencies taken from the CDIO Syllabus. This comparison indicates the degree of similarity among the lists and the possible convergence among universities all over the world. The results are taken from a survey carried out among Russian employers, academics, and graduates. The survey asked to rate each listed competence by its importance and the degree of achieving goals in the process of the education.

This paper describes part of a research and development project carried out in public elementary schools. Its objective was to update the mathematical and didactic knowledge of teachers in two consecutive levels in urban and rural public schools of Region de Los Lagos and Region de Los Rios of southern Chile. To that effect, and by means of an advanced training project based on a professional competences model, didactic interventions based on types of problems and types of mathematical competences with analysis of contents and learning assessment were designed. The teachers' competence regarding the didactic strategy used and its results, as well as the students' learning achievements are specified. The project made possible to validate a strategy of lifelong improvement in mathematics, based on the professional competences of teachers and their didactic transposition in the classroom, as an alternative to consolidate learning in areas considered vulnerable in two regions of the country.

A central part of providing evidence-based practice is appropriate cultural competence to facilitate psychological assessment and intervention with diverse clients. At a minimum, cultural competence with lesbian, gay, bisexual, and transgender (LGBT) people involves adequate scientific and supervised practical training, with increasing depth and complexity across training levels. In order to further this goal, we offer 28 recommendations of minimum standards moving toward ideal training for LGBT-specific cultural competence. We review and synthesize the relevant literature to achieve and assess competence across the various levels of training (doctoral, internship, post-doctoral, and beyond) in order to guide the field towards best practices. These recommendations are aligned with educational and practice guidelines set forth by the field and informed by other allied professions in order to provide a roadmap for programs, faculty, and trainees in improving the training of psychologists to work with LGBT individuals.
