    2002-01-01

    This article examines one outcome of leadership: productive achievement. Without achievement one is judged to not truly be a leader. Thus, the ideal leader must be a visionary, a critical thinker, an expert, a communicator, a mentor, and an achiever of organizational goals. This article explores the organizational context that supports achievement, measures of quality nursing care, fiscal accountability, leadership development, rewards and punishments, and the educational content and teaching strategies to prepare graduates to be achievers.

    Full Text Available AbstractToday, In order to create motivation and desirable behavior in employees, to obtain organizational goals,to increase human resources productivity and finally to achieve organizational excellence, top managers oforganizations apply new and effective strategies. One of these strategies to achieve organizational excellenceis creating desirable corporate culture. This research has been conducted to identify the path to reachorganizational excellence by creating corporate culture according to the standards and criteria oforganizational excellence. The result of the so-called research is this paper in which researchers foundtwenty models and components of corporate culture and based on the Industry, organizational goals andEFQM model developed a model called "The Eskimo model of Culture-Excellence". The method of theresearch is survey and field study and the questionnaires were distributed among 116 managers andemployees. To assess the reliability of questionnaires, Cronbach alpha was measured to be 95% in the idealsituation and 0/97 in the current situation. Systematic sampling was done and in the pre-test stage 45questionnaires were distributed. A comparison between the current and the ideal corporate culture based onthe views of managers and employees was done and finally it has been concluded that corporate culture isthe main factor to facilitate corporate excellence and success in order to achieve organizational effectiveness.The contribution of this paper is that it proposes a localized –applicable model of corporate excellencethrough reinforcing corporate culture.

  8. Achieving form in autobiography

    Directory of Open Access Journals (Sweden)

    Nicholas (Nick Meihuizen

    2014-06-01

    Full Text Available This article argues that, unlike biographies which tend to follow patterns based on conventional expectations, salient autobiographies achieve forms unique to themselves. The article draws on ideas from contemporary formalists such as Peter McDonald and Angela Leighton but also considers ideas on significant form stemming from earlier writers and critics such as P.N. Furbank and Willa Cather. In extracting from these writers the elements of what they consider comprise achieved form, the article does not seek to provide a rigid means of objectively testing the formal attributes of a piece of writing. It rather offers qualitative reminders of the need to be alert to the importance of form, even if the precise nature of this importance is not possible to define. Form is involved in meaning, and this continuously opens up possibilities regarding the reader’s relationship with the work in question. French genetic critic Debray Genette distinguishes between ‘semantic effect’ (the direct telling involved in writing and ‘semiological effect’ (the indirect signification involved. It is the latter, the article argues in summation, which gives a work its singular nature, producing a form that is not predictable but suggestive, imaginative.

  9. Achieving diagnosis by consensus

    Kane, Bridget

    2009-08-01

    This paper provides an analysis of the collaborative work conducted at a multidisciplinary medical team meeting, where a patient’s definitive diagnosis is agreed, by consensus. The features that distinguish this process of diagnostic work by consensus are examined in depth. The current use of technology to support this collaborative activity is described, and experienced deficiencies are identified. Emphasis is placed on the visual and perceptual difficulty for individual specialities in making interpretations, and on how, through collaboration in discussion, definitive diagnosis is actually achieved. The challenge for providing adequate support for the multidisciplinary team at their meeting is outlined, given the multifaceted nature of the setting, i.e. patient management, educational, organizational and social functions, that need to be satisfied.

    Speiss, Fred

    One function of any professional society is to provide an objective, informed means for recognizing outstanding achievements in its field. In AGU's Ocean Sciences section we have a variety of means for carrying out this duty. They include recognition of outstanding student presentations at our meetings, dedication of special sessions, nomination of individuals to be fellows of the Union, invitations to present Sverdrup lectures, and recommendations for Macelwane Medals, the Ocean Sciences Award, and the Ewing Medal.Since the decision to bestow these awards requires initiative and judgement by members of our section in addition to a deserving individual, it seems appropriate to review the selection process for each and to urge you to identify those deserving of recognition.

    Language is first and foremost oral,spoken language,speaking skill is the most important one of the four skills(L,S,R,W)and also it is the most difficult one of the four skills. To have an all-round command of a language one must be able to speak and to understand the spoken language, it is not enough for a language learner only to have a good reading and writing skills. As Englisn language teachers, we need to focus on improving learners' English speaking skill to meet the need of our society and our country and provide learner some useful techniques to achieving their English spoken fluency. This paper focuses on the spoken how to improving learners speaking skill.

  12. Achieving closure at Fernald

    Energy Technology Data Exchange (ETDEWEB)

    Bradburne, John; Patton, Tisha C.

    2001-02-25

    When Fluor Fernald took over the management of the Fernald Environmental Management Project in 1992, the estimated closure date of the site was more than 25 years into the future. Fluor Fernald, in conjunction with DOE-Fernald, introduced the Accelerated Cleanup Plan, which was designed to substantially shorten that schedule and save taxpayers more than $3 billion. The management of Fluor Fernald believes there are three fundamental concerns that must be addressed by any contractor hoping to achieve closure of a site within the DOE complex. They are relationship management, resource management and contract management. Relationship management refers to the interaction between the site and local residents, regulators, union leadership, the workforce at large, the media, and any other interested stakeholder groups. Resource management is of course related to the effective administration of the site knowledge base and the skills of the workforce, the attraction and retention of qualified a nd competent technical personnel, and the best recognition and use of appropriate new technologies. Perhaps most importantly, resource management must also include a plan for survival in a flat-funding environment. Lastly, creative and disciplined contract management will be essential to effecting the closure of any DOE site. Fluor Fernald, together with DOE-Fernald, is breaking new ground in the closure arena, and ''business as usual'' has become a thing of the past. How Fluor Fernald has managed its work at the site over the last eight years, and how it will manage the new site closure contract in the future, will be an integral part of achieving successful closure at Fernald.

    The Vietnamese Government's successful development of the National Population and Family Planning Program has contributed in raising people's awareness on population issues and changing their attitudes and behavior regarding fostering small families. It has also been found to be very effective in substantially decreasing fertility level. In addition, economic levels of many households have been greatly improved since the adoption of a renovation policy. The advancement of welfare accompanied by the provision of better basic social services, including health services, has boost people's health. Several factors behind the achievements of the National Population and Family Planning Program include: 1) Strengthening of the political commitment of national and local leaders; 2) Nationwide mobilization of mass organizations and NGOs; 3) A strong advocacy and information, education and communication program; 4) Provision of various kinds of contraceptives; 5) Effective management of the program by priority; and 6) Support of the international community. Despite such successes, Vietnam is facing a number of new issues such as enlargement of the work force, shifting migration patterns and accelerating urbanization, aging of population, and change of household structure. Nevertheless, the Government of Vietnam is preparing a New Population Strategy aimed to address these issues.

  17. Peer relationships and academic achievement

    Directory of Open Access Journals (Sweden)

    Krnjajić Stevan B.

    2002-01-01

    Full Text Available After their childhood, when children begin to establish more intensive social contacts outside family, first of all, in school setting, their behavior i.e. their social, intellectual, moral and emotional development is more strongly affected by their peers. Consequently, the quality of peer relationships considerably affects the process of adaptation and academic achievement and their motivational and emotional attitude towards school respectively. Empirical findings showed that there is bi-directional influence between peer relationships and academic achievement. In other words, the quality of peer relationships affects academic achievement, and conversely, academic achievement affects the quality of peer relationships. For example, socially accepted children exhibiting prosocial, cooperative and responsible forms of behavior in school most frequently have high academic achievement. On the other hand, children rejected by their peers often have lower academic achievement and are a risk group tending to delinquency, absenteeism and drop out of school. Those behavioral and interpersonal forms of competence are frequently more reliable predictors of academic achievement than intellectual abilities are. Considering the fact that various patterns of peer interaction differently exert influence on students' academic behavior, the paper analyzed effects of (a social competence, (b social acceptance/rejection, (c child's friendships and (d prosocial behavior on academic achievement.

  2. Disciplinary climate and student achievement

    DEFF Research Database (Denmark)

    Sortkær, Bent; Reimer, David

    Disciplinary climate has emerged as one of the single most important factors related to student achievement. Using data from the OECD Programme for International Student Assessment (PISA) 2003 for Canada, Denmark, Finland, Iceland, Latvia and Norway we find a significant and nontrivial association...... between the perceived disciplinary climate in the classroom and students’ mathematics performance in Canada, Denmark and Norway. Furthermore we exploit country specific class-size rules in order to single out a subsample with classroom-level data (PISA is sampled by age and not by classes) and find...... that the estimates based on school-level data might underestimate the relationship between disciplinary climate and student achievement. Finally we find evidence for gender differences in the association between disciplinary climate and student achievement that can partly be explained by gender-specific perceptions...

    Full Text Available In this study, I examined academic achievement of immigrant children in the United States, Canada, England, Australia, and New Zealand. Analyzing data from the Third International Mathematics and Science Study (TIMSS, I gauged the performance gaps relating to the generation of immigration and the home language background. I found immigrant children's math and science achievement to be lower than the others only in England, the U.S., and Canada. Non-English language background was found in each country to relate to poor math and science learning and this disadvantage was stronger among native-born children—presumably children of indigenous groups—than among immigrant children. I also examined the school variation in math performance gaps, using hierarchical linear modeling (HLM to each country's data. The patterns in which language- and generation-related math achievement gaps varied between schools are different in the five countries.

    1974-06-01

    The authors wished to study some of the internal psychological dynamics of achievement in a nonpatient identified high school population. Questionnaires were administered to the Grade 13 students and their parents in a large high school. A number of students whose achievement and educational plans were not congruous with their general background were selected for interview. The findings suggest that a wide variety of ages and developmental stages can be discerned as critical points in the development of a student's attitude toward higher education. These students have many values in common, and their values appear related to a positive or negative identification with parental values. The students themselves show a wide range of personality integration. They relate in a special way to a wide variety of teachers' personalities.

    A genome-wide polygenic score (GPS), derived from a 2013 genome-wide association study (N=127,000), explained 2% of the variance in total years of education (EduYears). In a follow-up study (N=329,000), a new EduYears GPS explains up to 4%. Here, we tested the association between this latest EduYears GPS and educational achievement scores at ages 7, 12 and 16 in an independent sample of 5825 UK individuals. We found that EduYears GPS explained greater amounts of variance in educational achievement over time, up to 9% at age 16, accounting for 15% of the heritable variance. This is the strongest GPS prediction to date for quantitative behavioral traits. Individuals in the highest and lowest GPS septiles differed by a whole school grade at age 16. Furthermore, EduYears GPS was associated with general cognitive ability (~3.5%) and family socioeconomic status (~7%). There was no evidence of an interaction between EduYears GPS and family socioeconomic status on educational achievement or on general cognitive ability. These results are a harbinger of future widespread use of GPS to predict genetic risk and resilience in the social and behavioral sciences. PMID:27431296

    Full Text Available Using data from a 50-state survey of policies, state case study analyses, the 1993-94 Schools and Staffing Surveys (SASS, and the National Assessment of Educational Progress (NAEP, this study examines the ways in which teacher qualifications and other school inputs are related to student achievement across states. The findings of both the qualitative and quantitative analyses suggest that policy investments in the quality of teachers may be related to improvements in student performance. Quantitative analyses indicate that measures of teacher preparation and certification are by far the strongest correlates of student achievement in reading and mathematics, both before and after controlling for student poverty and language status. State policy surveys and case study data are used to evaluate policies that influence the overall level of teacher qualifications within and across states. This analysis suggests that policies adopted by states regarding teacher education, licensing, hiring, and professional development may make an important difference in the qualifications and capacities that teachers bring to their work. The implications for state efforts to enhance quality and equity in public education are discussed.

    The 4th European Congress of Virology, hosted by the Italian Society for Virology, attracted approximately 1300 scientists from 46 countries worldwide. It also represented the first conference of the European Society for Virology, which was established in Campidoglio, Rome, Italy in 2009. The main goal of the meeting was to share research activities and results achieved in European virology units/institutes and to strengthen collaboration with colleagues from both western and developing countries. The worldwide representation of participants is a testament to the strength and attraction of European virology. The 5-day conference brought together the best of current virology; topics covered all three living domains (bacteria, archaea and eucarya), with special sessions on plant and veterinary virology as well as human virology, including two oral presentations on mimiviruses. The conference included five plenary sessions, 31 workshops, one hepatitis C virus roundtable, ten special workshops and three poster sessions, as well as 45 keynote lectures, 191 oral presentations and 845 abstracts. Furthermore, the Gesellschaft fur Virologie Loeffler-Frosch medal award was given to Peter Vogt for his long-standing career and achievements; the Gardner Lecture of the European Society for Clinical Virology was presented by Yoshihiro Kawaoka, and the Pioneer in Virology Lecture of the Italian Society for Virology was presented by Ulrich Koszinowski.

  1. Capacity-achieving CPM schemes

    Perotti, Alberto; Benedetto, Sergio; Montorsi, Guido

    2008-01-01

    The pragmatic approach to coded continuous-phase modulation (CPM) is proposed as a capacity-achieving low-complexity alternative to the serially-concatenated CPM (SC-CPM) coding scheme. In this paper, we first perform a selection of the best spectrally-efficient CPM modulations to be embedded into SC-CPM schemes. Then, we consider the pragmatic capacity (a.k.a. BICM capacity) of CPM modulations and optimize it through a careful design of the mapping between input bits and CPM waveforms. The so obtained schemes are cascaded with an outer serially-concatenated convolutional code to form a pragmatic coded-modulation system. The resulting schemes exhibit performance very close to the CPM capacity without requiring iterations between the outer decoder and the CPM demodulator. As a result, the receiver exhibits reduced complexity and increased flexibility due to the separation of the demodulation and decoding functions.

    Full Text Available Pupils with cerebral palsy attend elementary education accordind to a regular and special teaching plan and program. Regular school curriculum was reformed in 1992, while special plan and program has not been changed and adapted according to pupil’s needs and capacities. Music is one of the best means of expressing oneself and plays a very important role in the development of every child, the child with cerebral palsy in particular.In order to test the possibility of pupils with cerebral palsy, with and without mental retardation, to apprehend the actual program content, we have conducted research on musical achievement of children with cerebral palsy. During 2007 a research was carried out, on the sample of 27 pupils with cerebral palsy and mild mental retardation who attended classes in the school “Miodrag Matikj”, and a sample of16 students with cerebral palsy without mental retardation who attended the school “Dr. Dragan Hercog” in Belgrade.Results of the research, as well as analysis of music curriculum content, indicated that the capacities of students with cerebral palsy to carry out the curriculum tasks require special approach and methodology. Therefore, we introduced some proposals to overcome the difficulties in fulfilling music curriculum demands of those pupils. We made special emphasis on the use of computer based Assistive technology which facilitates the whole process to a large extent.

    The literature has long pointed to heightened frequencies of learning disabilities (LD) within the population of law offenders; however, a systematic appraisal of these observations, careful estimation of these frequencies, and investigation of their correlates and causes have been lacking. Here we present data collected from all youth (1,337 unique admissions, mean age 14.81, 20.3% females) placed in detention in Connecticut (January 1, 2010-July 1, 2011). All youth completed a computerized educational screener designed to test a range of performance in reading (word and text levels) and mathematics. A subsample (n = 410) received the Wide Range Achievement Test, in addition to the educational screener. Quantitative (scale-based) and qualitative (grade-equivalence-based) indicators were then analyzed for both assessments. Results established the range of LD in this sample from 13% to 40%, averaging 24.9%. This work provides a systematic exploration of the type and severity of word and text reading and mathematics skill deficiencies among juvenile detainees and builds the foundation for subsequent efforts that may link these deficiencies to both more formal, structured, and variable definitions and classifications of LD, and to other types of disabilities (e.g., intellectual disability) and developmental disorders (e.g., ADHD) that need to be conducted in future research.

  4. Achieving monospermy or preventing polyspermy?

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available Brian Dale Centre for Assisted Fertilization, Naples, Italy Abstract: Images of sea urchin oocytes with hundreds of spermatozoa attached to their surface have fascinated scientists for over a century and led to the idea that oocytes have evolved mechanisms to allow the penetration of one spermatozoon while repelling supernumerary spermatozoa. Popular texts have extrapolated this concept, to the mammals and amphibians, and in many cases to include all the Phyla. Here, it is argued that laboratory experiments, using sea urchin oocytes deprived of their extracellular coats and inseminated at high densities, are artifactual and that the experiments leading to the idea of a fast block to polyspermy are flawed. Under natural conditions, the number of spermatozoa at the site of fertilization is extremely low, compared with the numbers generated. The sperm:oocyte ratio is regulated first by dilution in externally fertilizing species and the female reproductive tract in those with internal fertilization, followed by a bottleneck created by the oocytes extracellular coats. In order to progress to the oocyte plasma membrane, the fertilizing spermatozoon must encounter and respond to a correct sequence of signals from the oocytes extracellular coats. Those that do not, are halted in their progression by defective signaling and fall to the wayside. Final success and entry is finely tuned by the spermatozoon anchoring to an actin-rich predetermined site on the plasma membrane. In this review, the variation in the form, function, and number of gametes produced across the animal kingdom and the many ways in which sperm–oocyte interactions are regulated to reduce numbers are discussed. Since in nature, final sperm:oocyte ratios approach unity it would appear that selective pressures have favored the achievement of monospermy, rather than the evolution of polyspermy preventing mechanisms. Keywords: monospermy, natural conditions, polyspermy, laboratory

    Steiner, Eric T; Ashcraft, Mark H

    2012-12-01

    Because of wide disparities in college students' math knowledge-that is, their math achievement-studies of cognitive processing in math tasks also need to assess their individual level of math achievement. For many research settings, however, using existing math achievement tests is either too costly or too time consuming. To solve this dilemma, we present three brief tests of math achievement here, two drawn from the Wide Range Achievement Test and one composed of noncopyrighted items. All three correlated substantially with the full achievement test and with math anxiety, our original focus, and all show acceptable to excellent reliability. When lengthy testing is not feasible, one of these brief tests can be substituted.

    General Chemistry is required for variety of baccalaureate degrees, including all medical related fields, engineering, and science majors. Depending on the institution, the prerequisite requirement for college level General Chemistry varies. The success rate for this course is low. The purpose of this study is to examine the factors influencing student academic achievement and retention in General Chemistry at the college level. In this study student achievement is defined by those students who earned grades of "C" or better. The dissertation contains in-depth studies on influence of Intermediate Algebra as a prerequisite compared to Fundamental Chemistry for student academic achievement and student retention in college General Chemistry. In addition the study examined the extent and manner in which student self-efficacy influences student academic achievement in college level General Chemistry. The sample for this part of the study is 144 students enrolled in first semester college level General Chemistry. Student surveys determined student self-efficacy level. The statistical analyses of study demonstrated that Fundamental Chemistry is a better prerequisite for student academic achievement and student retention. The study also found that student self-efficacy has no influence on student academic achievement. The significance of this study will be to provide data for the purpose of establishing a uniform and most suitable prerequisite for college level General Chemistry. Finally the variables identified to influence student academic achievement and enhance student retention will support educators' mission to maximize the students' ability to complete their educational goal at institutions of higher education.

    The utility of limited feedback for coding over an individual sequence of DMCs is investigated. This study complements recent results showing how limited or noisy feedback can boost the reliability of communication. A strategy with fixed input distribution $P$ is given that asymptotically achieves rates arbitrarily close to the mutual information induced by $P$ and the state-averaged channel. When the capacity achieving input distribution is the same over all channel states, this achieves rates at least as large as the capacity of the state averaged channel, sometimes called the empirical capacity.

    The influence of students' sociocultural background on academic achievement is a well established fact. Research also points out that sociocultural background is related to students' cognitive abilities and these have an effect on their academic achievement. However, the mediator role of cognitive abilities on the relationship between sociocultural background and academic achievement is less well known. A structural equation model that represents these relationships was tested in a sample (N= 728) of Portuguese junior high school students. Multigroup analysis of the model showed the importance of the cognitive ability mediation effect between sociocultural background and academic achievement in the 7th and 9th grades, but not in the 8th grade. This difference may be the result of the academic transition experienced in the 7th and 9th grades in the Portuguese educational system, which requires parents' higher involvement in school.

    2007-05-01

    Full Text Available We used an achievement goal framework to study the role of motivation in the academic context of a Peruvian sample of 8th to 10th grade high school students (N = 1505. The purpose of this cross-sectional study was to examine the relationship between students' achievement goals, their use of learning strategies and their academic achievement. Multiple Hierarchical Regressions Analyses identified, as predicted, positive effects of mastery goals, including more use of learning strategies and higher academic achievement, and negative effects of performance avoidance goals, including lower academic achievement. Mixed results were found for pursuing performance approach goals, which predicted a greater use of learning strategies, but were unrelated to academic achievement. The present findings support the external validity of achievement goal theory in a sample of students from a culture that is understudied in the achievement goal literature in particular and the motivational literature in general.

    2014-11-01

    Full Text Available Much of the focus in the literature in raising student achievement has included parental involvement, principal leadership, quality of instruction, students’ socioeconomic status, curriculum, and use of technology. Limited empirical research relates the condition of the school building as a variable that affects student achievement. Furthermore, there is no research that has examined the impact of building codes on achievement outcomes in the state of Florida. This research determined whether academic achievement of 4th-, 8th-, 9th-, and 10th-grade students as measured by the mathematics and reading subtests of the Florida Comprehensive Achievement Test (FCAT increased in new school buildings compliant to the 2000 Florida State Requirements for Educational Facilities. A causal-comparative design determined whether the independent variables, old and new school building influenced student achievement as measured by students’ FCAT mathematics and reading subtest scores. The control group was two cohorts of 4th-, 8th-, 9th-, and 10th-grade students who attended school in old buildings. The experimental group was two cohorts of 4th-, 8th-, 9th-, and 10th-grade students who attended school in new buildings. Transition from an old school into a new school was the treatment. Two hypotheses were formulated for testing and the research question for the inquiry was whether the percentage of students passing the FCAT mathematics and reading subtests increases after transitioning from an old school building into a new 2000 UBC (Uniform Building Code compliant facility.

    2009-07-01

    Full Text Available Recent psychological studies highlight emotional aspects, and they show an important role within individual learning processes. Hereby, positive emotions were supposed to positively influence learning and achievement processes and negative ones do the contrary. In this study, an educational unit “ecosystem lake” was used during which achievement (three tests and emotional variables (interest, well-being, anxiety and boredom; measured at the end of three pre-selected lessons were monitored. The research question was to explore correlations between emotional variables and the learning outcome of the teaching unit. Prior knowledge was regressed against the subsequent tests to account for its confounding effect. Regressions showed a highly significant influence of prior knowledge on the subsequent measurements of achievement. However, after accounting for prior knowledge, a positive correlation between interest/well-being and achievement and a negative correlation between anxiety/boredom and achievement was found. Further research and interventions should try to enhance positive emotions in biology lessons to positively influence achievement.

  12. Student self-esteem and academic achievement

    Directory of Open Access Journals (Sweden)

    Milošević Nikoleta M.

    2005-01-01

    Full Text Available There is a growing belief that academic achievement is the product of a complex network of teacher-student relations, where the identity of successful and unsuccessful student is developing with high, moderate or low self-esteem level. Self-esteem is most often defined as a conscious cognitive-affective expression of self-evaluation which is one of the most immediate indicators of self-concept integration degree. A number of authors view high self-esteem level as an important prerequisite for high academic achievement. In contrast, academic achievement and other experiences related to teaching and learning are considered to exert significant influence on self-esteem and a student should be successful at school first so as to develop a positive self-image and his academic abilities. The debate on what comes first - self-esteem or academic achievement - is in its character more academic than practical. This claim is supported by an increasing number of studies indicating the dynamism and reciprocity of correlation between academic achievement and self-esteem. The paper gives recommendations for educational practice to promote self-esteem and development of personal and social responsibility, which contributes to better student academic achievement. It is pointed out that teacher education in the field is necessary and that self-esteem and responsibility must become essential segments of curricula. Teacher is expected to become sensitive to the needs of students who are at risk to be unsuccessful and to largely apply cooperative learning methods. Findings demonstrate that cooperative learning either sustain or increase student self-esteem, whereas traditional teaching methods, in general, lead to its decline. Cooperative relations improve student self-image in respect of academic abilities and social interactions. Positive feedback, peer support, more frequent experience of learning achievement leads mainly to general increase in self-esteem and

    Full Text Available The urge to excel or perform maximally in mathematics varies from individual to individual because achievement motivation is often developed or learnt during socialization and learning experiences. The study examined the relationship between College of Education students’ achievement motivation and mathematics achievement, correlation coefficient between mathematics anxiety and college students’ achievement motivation as well as mathematics anxiety and mathematics achievement. The sample, 268 College of Education students offering mathematics as one of their subject combination, was selected using purposive sampling techniques. Three research instruments namely: Mathematics Anxiety Scale (MAS, Achievement Motivation Scale (AMS and Mathematics Achievement Test (MAT were used to collect data for the study. Data collected for the study were analyzed using correlational analysis and ANOVA. The results showed that a significantly low negative correlation coefficient existed between mathematics anxiety and mathematics achievement. There is a negative and significant correlation coefficient between mathematics anxiety and achievement motivation. Similarly, a positive and significant correlation coefficient also exists between achievement motivation and mathematics achievement. Based on the findings of the study, it was recommended that mathematics teachers should adopt activity based strategies and conducive learning environment in order to reduce college students’ anxieties in mathematics learning.

    Grayson, Kristin

    This study examined the relationships between teacher leadership, science teacher self-efficacy, and fifth-grade science student achievement in diverse schools in a San Antonio, Texas, metropolitan school district. Teachers completed a modified version of the Leadership Behavior Description Question (LBDQ) Form XII by Stogdill (1969), the Science Efficacy and Belief Expectations for Science Teaching (SEBEST) by Ritter, Boone, and Rubba (2001, January). Students' scores on the Texas Assessment of Knowledge and Skills (TAKS) measured fifth-grade science achievement. At the teacher level of analysis multiple regressions showed the following relationships between teachers' science self-efficacy and teacher classroom leadership behaviors and the various teacher and school demographic variables. Predictors of teacher self efficacy beliefs included teacher's level of education, gender, and leadership initiating structure. The only significant predictor of teacher self-efficacy outcome expectancy was gender. Higher teacher self-efficacy beliefs predicted higher leadership initiating structure. At the school level of analysis, higher school levels of percentage of students from low socio-economic backgrounds and higher percentage of limited English proficient students predicted lower school student mean science achievement. These findings suggest a need for continued research to clarify relationships between teacher classroom leadership, science teacher self-efficacy, and student achievement especially at the teacher level of analysis. Findings also indicate the importance of developing instructional methods to address student demographics and their needs so that all students, despite their backgrounds, will achieve in science.

    Achievable RMS errors in estimating the phase, frequency, and intensity of a direct-detected intensity-modulated optical pulse train are presented. For each parameter, the Cramer-Rao-Bound (CRB) is derived and the performance of the Maximum Likelihood estimator is illustrated. Approximations to the CRBs are provided, enabling an intuitive understanding of estimator behavior as a function of the signaling parameters. The results are compared to achievable RMS errors in estimating the same parameters from a sinusoidal waveform in additive white Gaussian noise. This establishes a framework for a performance comparison of radio frequency (RF) and optical science. Comparisons are made using parameters for state-of-the-art deep-space RF and optical links. Degradations to the achievable errors due to clock phase noise and detector jitter are illustrated.

    KAUST Repository

    Choi, Jung Il

    2010-01-01

    This paper discusses the design of a single channel full-duplex wireless transceiver. The design uses a combination of RF and baseband techniques to achieve full-duplexing with minimal effect on link reliability. Experiments on real nodes show the full-duplex prototype achieves median performance that is within 8% of an ideal full-duplexing system. This paper presents Antenna Cancellation, a novel technique for self-interference cancellation. In conjunction with existing RF interference cancellation and digital baseband interference cancellation, antenna cancellation achieves the amount of self-interference cancellation required for full-duplex operation. The paper also discusses potential MAC and network gains with full-duplexing. It suggests ways in which a full-duplex system can solve some important problems with existing wireless systems including hidden terminals, loss of throughput due to congestion, and large end-to-end delays.

    2017-02-01

    Full Text Available In this study, the effects of blended learning on the middle school students’ academic achievement level and product evaluation scores were investigated. Blended learning provides more effective learning outcome gains through enriching todays’ developing Web Technologies with learning environments. This study was carried out with a total of 53 students enrolled in the experimental group and control group in the 6th grade classrooms during the 2014/2015 school year in a middle school in southwest part of Turkey. The intervention lasted 7 weeks. During the seven weeks, the unit of “problem solving, computer programming and development of Software product”, covered in Educational technologies and Software course, is taught through blended learning environment. The experimental group was taught using blended learning environment which supported with enriched web technologies (such as video-conference, Learning Management System, Discussion blogs , etc.. Whereas the experimental group was given access to all these enriched contents that are presented to the control group only during the classroom environment through present teaching methods. The design of the study includes quantitative method. We collected quantitative data such as academic achievement test and product evaluation scale. Academic achievement test and product evaluation scale were used as quantitative data collection sources. Quantitative data was collected through the evaluation of students’ projects that they developed during the process of the study and the academic achievement tests. During the data analysis phase, independent t-test, frequency and ANOVA tests were used. As a result of this study, it is concluded that blended learning environment had generated a significant difference in students’ academic achievement on behalf of experimental group. Implications of the study for the educational environments were discussed.

    Identifying the types of mathematics content knowledge that are most predictive of students' long-term learning is essential for improving both theories of mathematical development and mathematics education. To identify these types of knowledge, we examined long-term predictors of high school students' knowledge of algebra and overall mathematics achievement. Analyses of large, nationally representative, longitudinal data sets from the United States and the United Kingdom revealed that elementary school students' knowledge of fractions and of division uniquely predicts those students' knowledge of algebra and overall mathematics achievement in high school, 5 or 6 years later, even after statistically controlling for other types of mathematical knowledge, general intellectual ability, working memory, and family income and education. Implications of these findings for understanding and improving mathematics learning are discussed.

    Full Text Available The paper considers correlation between student prosocial behavior and academic achievement. Attention first focuses on the issue of prosocial behavior defining, making it operational and measuring it. Next consideration is given to the ways that prosocial behavior contributes to academic achievement. It is thought that prosocial behavior can produce indirect effects on student prosocial behavior because it is bound to certain academically relevant forms of behavior leading to successful learning and work. Also, correlation is interpreted by means of teacher’s preferences of prosocial students, which is reflected in teacher expectations and behavior towards students but in evaluating their work too. In addition, prosocial behavior may produce direct effects, for it is through peer prosocial interactions that positive intellectual exchange is performed, which contributes to more successful mastering of teaching content. The paper provides a survey of investigations whose results indicate that there exists correlation between student prosocial behavior and academic achievement. Also, consideration is given to possible methods and treatments for encouraging prosocial behavior in school context, especially the role of teacher in the process and the importance of the program for promoting student prosocial skills.

    Recently, metal halide perovskite based solar cell with the characteristics of rather low raw materials cost, great potential for simple process and scalable production, and extreme high power conversion efficiency (PCE), have been highlighted as one of the most competitive technologies for next generation thin film photovoltaic (PV). In UCLA, we have realized an efficient pathway to achieve high performance pervoskite solar cells, where the findings are beneficial to this unique materials/devices system. Our recent progress lies in perovskite film formation, defect passivation, transport materials design, interface engineering with respect to high performance solar cell, as well as the exploration of its applications beyond photovoltaics. These achievements include: 1) development of vapor assisted solution process (VASP) and moisture assisted solution process, which produces perovskite film with improved conformity, high crystallinity, reduced recombination rate, and the resulting high performance; 2) examination of the defects property of perovskite materials, and demonstration of a self-induced passivation approach to reduce carrier recombination; 3) interface engineering based on design of the carrier transport materials and the electrodes, in combination with high quality perovskite film, which delivers 15 ~ 20% PCEs; 4) a novel integration of bulk heterojunction to perovskite solar cell to achieve better light harvest; 5) fabrication of inverted solar cell device with high efficiency and flexibility and 6) exploration the application of perovskite materials to photodetector. Further development in film, device architecture, and interfaces will lead to continuous improved perovskite solar cells and other organic-inorganic hybrid optoelectronics.

  9. Are Reductions in Population Sodium Intake Achievable?

    Jessica L. Levings

    2014-10-01

    Full Text Available The vast majority of Americans consume too much sodium, primarily from packaged and restaurant foods. The evidence linking sodium intake with direct health outcomes indicates a positive relationship between higher levels of sodium intake and cardiovascular disease risk, consistent with the relationship between sodium intake and blood pressure. Despite communication and educational efforts focused on lowering sodium intake over the last three decades data suggest average US sodium intake has remained remarkably elevated, leading some to argue that current sodium guidelines are unattainable. The IOM in 2010 recommended gradual reductions in the sodium content of packaged and restaurant foods as a primary strategy to reduce US sodium intake, and research since that time suggests gradual, downward shifts in mean population sodium intake are achievable and can move the population toward current sodium intake guidelines. The current paper reviews recent evidence indicating: (1 significant reductions in mean population sodium intake can be achieved with gradual sodium reduction in the food supply, (2 gradual sodium reduction in certain cases can be achieved without a noticeable change in taste or consumption of specific products, and (3 lowering mean population sodium intake can move us toward meeting the current individual guidelines for sodium intake.

    Alkali vapor lasers are under extensive research and development during the past decade because of their potential for scaling to high powers while maintaining a good beam quality. Also, a possibility of using efficient diode lasers for pumping alkali vapor promises high total wall plug efficiency for a Diode Pumped Alkali Laser (DPAL). Since the first DPAL demonstration with output power of 130 mW in 20051, a significant progress in this field was achieved. The output power of about 1 kW in continuous wave (CW) operation with optical efficiency close to 50% was recently demonstrated for a Cs DPAL2. Also, the DPALs based on other alkali metals (Rubidium and Potassium) were demonstrated3,4 . In spite of these significant achievements, there are still several problems in DPAL power scaling exist that must be addressed. Among them are the thermal5 and photoionization6 issues that become important even at power level about several tens of watts. In this paper we present a historical review of the alkali laser research and development, discuss the most important achievements and future perspectives in this field of research.

    Full Text Available Social-emotional learning (SEL programs have demonstrated positive effects on children’s social-emotional, behavioral, and academic outcomes, as well as classroom climate. Some programs also theorize that program impacts on children’s outcomes will be partially explained by improvements in classroom social processes, namely classroom emotional support and organization. Yet there is little empirical evidence for this hypothesis. Using data from the evaluation of the SEL program INSIGHTS, this article tests whether assignment to INSIGHTS improved low-income kindergarten and first grade students’ math and reading achievement by first enhancing classroom emotional support and organization. Multilevel regression analyses, instrumental variables estimation, and inverse probability of treatment weighting (IPTW were used to conduct quantitative analyses. Across methods, the impact of INSIGHTS on math and reading achievement in first grade was partially explained by gains in both classroom emotional support and organization. The IPTW method revealed that the program impact on reading achievement in first grade was partially explained through an improvement in classroom organization. Implications for research and practice are discussed.

    The purpose of this study was to investigate the two dimensional theory of achievement motivation (Doi, 1982) in female students. Doi's motivation scale were administered to 81 female university students, 58 female students of school of nursing and 77 female students of school of English Language, and the Yatabe-Guilford personality inventory was also administered to the first and the second groups. Affiliative achievement motivation and non-affiliative achievement motivation were extracted by principal component analyses and canonical correlation analyses. Non-affiliative achievement motivation was found to be related to personality type: emotional instability and introversion. These findings differ from achievement motivation concepts (Murray, 1938; McClelland, Atkinson, Clark, & Lowell, 1953), that include emotional stability and extraversion.

    This study used nationwide data from the Taiwan Education Panel Survey (TEPS) to examine the longitudinal effects of educational expectations and achievement attributions on the academic achievements of adolescents. The sample included 2,000 Taiwanese secondary school students, each of whom completed three waves of questionnaires and cognitive tests: the first in grade 7 (in 2001), the second in grade 9 (in 2003), and the third in grade 11 (in 2005). Through multilevel longitudinal analysis, the results showed: (1) educational expectations accounted for a moderate amount of the variance in academic achievements; (2) students with high educational expectations and effort attribution exhibited higher growth rates in their academic achievements; and (3) studentswith lower educational expectations and those attributing success to others showed significantly fewer academic achievements and significantly lower growth rates in such achievements. The results demonstrated that adolescents' educational expectations and achievement attributions play crucial roles in the long-term course of academic accomplishments. Implications for educational practice and further studies are also discussed.

    As the new millennium approaches, a long anticipated reckoning for the education system of the United States is forthcoming, Years of school reform initiatives have not yielded the anticipated results. A particularly perplexing problem involves the lack of significant improvement of student achievement in math and science. Three "Partnership" projects represent collaborative efforts between Xavier University (XU) of Louisiana, Southern University of New Orleans (SUNO), Mississippi Valley State University (MVSU), and the National Aeronautics and Space Administration (NASA), Stennis Space Center (SSC), to enhance student achievement in math and science. These "Partnerships" are focused on students and teachers in federally designated rural and urban empowerment zones and enterprise communities. The major goals of the "Partnerships" include: (1) The identification and dissemination of key indices of success that account for high performance in math and science; (2) The education of pre-service and in-service secondary teachers in knowledge, skills, and competencies that enhance the instruction of high school math and science; (3) The development of faculty to enhance the quality of math and science courses in institutions of higher education; and (4) The incorporation of technology-based instruction in institutions of higher education. These goals will be achieved by the accomplishment of the following objectives: (1) Delineate significant ?best practices? that are responsible for enhancing student outcomes in math and science; (2) Recruit and retain pre-service teachers with undergraduate degrees in Biology, Math, Chemistry, or Physics in a graduate program, culminating with a Master of Arts in Curriculum and Instruction; (3) Provide faculty workshops and opportunities for travel to professional meetings for dissemination of NASA resources information; (4) Implement methodologies and assessment procedures utilizing performance-based applications of higher order

  15. Media and attention, cognition, and school achievement.

    Schmidt, Marie Evans; Vandewater, Elizabeth A

    2008-01-01

    Marie Evans Schmidt and Elizabeth Vandewater review research on links between various types of electronic media and the cognitive skills of school-aged children and adolescents. One central finding of studies to date, they say, is that the content delivered by electronic media is far more influential than the media themselves. Most studies, they point out, find a small negative link between the total hours a child spends viewing TV and that child's academic achievement. But when researchers take into account characteristics of the child, such as IQ or socioeconomic status, this link typically disappears. Content appears to be crucial. Viewing educational TV is linked positively with academic achievement; viewing entertainment TV is linked negatively with achievement. When it comes to particular cognitive skills, say the authors, researchers have found that electronic media, particularly video games, can enhance visual spatial skills, such as visual tracking, mental rotation, and target localization. Gaming may also improve problem-solving skills. Researchers have yet to understand fully the issue of transfer of learning from electronic media. Studies suggest that, under some circumstances, young people are able to transfer what they learn from electronic media to other applications, but analysts are uncertain how such transfer occurs. In response to growing public concern about possible links between electronic media use and attention problems in children and adolescents, say the authors, researchers have found evidence for small positive links between heavy electronic media use and mild attention problems among young people but have found only inconsistent evidence so far for a link between attention deficit hyperactivity disorder and media use. The authors point out that although video games, interactive websites, and multimedia software programs appear to offer a variety of possible benefits for learning, there is as yet little empirical evidence to suggest that

    2014-08-01

    Early retirement incentives (ERIs) are increasingly prevalent in education as districts seek to close budget gaps by replacing expensive experienced teachers with lower-cost newer teachers. Combined with the aging of the teacher workforce, these ERIs are likely to change the composition of teachers dramatically in the coming years. We use exogenous variation from an ERI program in Illinois in the mid-1990s to provide the first evidence in the literature of the effects of large-scale teacher retirements on student achievement. We find the program did not reduce test scores; likely, it increased them, with positive effects most pronounced in lower-SES schools.

    Humor can be found everywhere in our daily life. It shows one's wisdom and confidence, which reflects a person's character, mind and cultivation. While it makes people laugh, it enlightens and instruct people. As we all know, English humor is a manifestation of the western literature. However, people in non-English speaking countries cannot completely understand English humor because of the differences of different cultures. The present paper starts from the analysis of English humor, trying to find out some ways of achieving humor so as to better our understanding and appreciation of English humor.

    The role and share of photovoltaic (PV) generated electricity in our nation`s future energy arsenal is primarily dependent on its future production cost. This paper provides a framework for obtaining a minimum achievable electrical generating cost (a lower bound) for fixed, flat-plate photovoltaic systems. A cost of 2.8 $cent/kWh (1990$) was derived for a plant located in Southwestern USA sunshine using a cost of money of 8%. In addition, a value of 22 $cent/Wp (1990$) was estimated as a minimum module manufacturing cost/price

    We consider the feedback control of quantum systems comprised of any number of bosonic degrees of freedom. We derive a general upper bound for the logarithmic negativity achievable, at steady state, with continuous Gaussian measurements on the environment and linear driving on the system. Our results apply to rotating wave system-bath couplings and to any quadratic system's Hamiltonian. Furthermore, we apply this upper bound to parametric processes, show it to be tight, and compare it to feedback strategies limited to local measurements.

    The facial expressions and body postures of dogs can give helpful information about their moods and emotional states. People can more effectively obedience train their dogs if we can identify the mannerisms associated with learning in dogs. The aim of this study was to clarify the dog's body language during operant conditioning to predict achievement in the test that followed by measuring the duration of behaviors. Forty-six untrained dogs (17 males and 26 females) of various breeds were used. Each session consisted of 5 minutes of training with a treat reward followed by 3 minutes of rest and finally an operant conditioning test that consisted of 20 "hand motion" cues. The operant tests were conducted a total of nine times over three consecutive days, and the success numbers were counted. The duration of the dog's behavior, focusing on the dog's eyes, mouth, ears, tail and tail-wagging, was recorded during the operant conditioning sessions before the test. Particular behaviors, including wide-eyes, closed mouth, erect ears, and forward and high tail carriage, without wagging or with short and quick wagging, related to high achievement results. It is concluded that dogs' body language during operant conditioning was related to their success rate.

    Full Text Available ieving the Renewable Energy Target for Jamaica Abstract: The high cost of energy in Jamaica, one of the highest in the Caribbean region, is usually cited as a hindrance to industrial development and efficiency, especially in the manufacturing sector. High energy cost is also considered to be a national energy security issue and the government is taking steps to ensure adequate supply of energy at affordable prices. In the current National Development Plan, the government has set a target for renewable energy sources to supply 20% of the country's energy need by the year 2030. Using a linear programing model of energy planning, we examine how realistically this target could be achieved. Our findings indicate that the 20% renewable energy target is technically achievable with the optimal plan showing a mixture of wind power, hydropower and bagasse power but no solar power. However, when the timeline for investment in new generating capacities that will ensure the attainment of the target is considered, it becomes highly improbable that the target will be met. This study fills the gap that exists in evidence-based analysis of energy policy in Jamaica.

  6. Understanding how animal groups achieve coordinated movement.

    Herbert-Read, J E

    2016-10-01

    Moving animal groups display remarkable feats of coordination. This coordination is largely achieved when individuals adjust their movement in response to their neighbours' movements and positions. Recent advancements in automated tracking technologies, including computer vision and GPS, now allow researchers to gather large amounts of data on the movements and positions of individuals in groups. Furthermore, analytical techniques from fields such as statistical physics now allow us to identify the precise interaction rules used by animals on the move. These interaction rules differ not only between species, but also between individuals in the same group. These differences have wide-ranging implications, affecting how groups make collective decisions and driving the evolution of collective motion. Here, I describe how trajectory data can be used to infer how animals interact in moving groups. I give examples of the similarities and differences in the spatial and directional organisations of animal groups between species, and discuss the rules that animals use to achieve this organisation. I then explore how groups of the same species can exhibit different structures, and ask whether this results from individuals adapting their interaction rules. I then examine how the interaction rules between individuals in the same groups can also differ, and discuss how this can affect ecological and evolutionary processes. Finally, I suggest areas of future research.

    2016-11-01

    Housing cost burden-the fraction of income spent on housing-is the most prevalent housing problem affecting the healthy development of millions of low- and moderate-income children. By affecting disposable income, a high burden affects parents' expenditures on both necessities for and enrichment of their children, as well as investments in their children. Reducing those expenditures and investments, in turn, can affect children's development, including their cognitive skills and physical, social, and emotional health. This article summarizes the first empirical evidence of the effects of housing affordability on children's cognitive achievement and on one factor that appears to contribute to these effects: the larger expenditures on child enrichment by families in affordable housing. We found that housing cost burden has the same relationship to both children's cognitive achievement and enrichment spending on children, exhibiting an inverted U shape in both cases. The maximum benefit occurs when housing cost burden is near 30 percent of income-the long-standing rule-of-thumb definition of affordable housing. The effect of the burden is stronger on children's math ability than on their reading comprehension and is more pronounced with burdens above the 30 percent standard. For enrichment spending, the curve is "shallower" (meaning the effect of optimal affordability is less pronounced) but still significant.

    Full Text Available The land fund of Romania represents a huge potential for agriculture. The potential has proved difficult to achieve, and among the main vulnerabilities researched lately, we have identified the decline in consumption of vegetable crops, fruit and meat, determined by the declining purchasing power in Romania and the European Union's common market. Therefore the degree of achievement of the agricultural potential is directly influenced by economic developments in Romania and EU Member States. The technical endowment of Romanian farmers is an old and still unresolved problem. Even though Romania has benefited from EU pre-accession funds and still benefits from it, they proved to be a poor solution for Romanian farmers with farm machinery equipment. Indicator analysis of the evolution of the number of tractors in Romania in the post-accession period, reveals that the actual number of tractors in the period under review increased overall, but even if the total number of tractors in Romania increased from 2007 until 2012, UAA (ha per a tractor is almost constant.

    Evans, Michael S.

    2010-03-01

    Scientists tell a story of 2,000 years of stellar magnitude research that traces back to Hipparchus. This story of continuity in practices serves an important role in scientific education and outreach. STS scholars point out many ways that stories of continuity, like many narratives about science, are disconnected from practices. Yet the story of continuity in stellar magnitude is a powerful scientific achievement precisely because of its connection to practice. The historical development of star catalogues shows how specific recording practices connected past and present in a useful way. The narrative of continuity in stellar magnitude, however else it might be subject to STS critique of narrative, maintains its power because of its connection to practice. I suggest that more attention be paid to connections between practice and narrative in STS, and in particular to the ways that historical practices sustain narratives by connecting past and present.

For a successful implementation of array processing methods exploiting the full potential, the desired radar task has to be considered and all processing necessary for this task has to be eventually adapted. In this tutorial paper, we point out several viewpoints which are relevant in this context: the restrictions and the potential provided by different array configurations, the predictability of the transmission function of the array, the constraints for adaptive beamforming, the inclusion of monopulse, detection and tracking into the adaptive beamforming concept, and the assessment of superresolution methods with respect to their application in a radar system. The problems and achieved results are illustrated by examples from previous publications.

    Full Text Available Research indicates that educational, economic, and life success reflect children’s nonacademic as well as academic competencies. Therefore, longitudinal surveys that assess educational progress and success need to incorporate nonacademic measures to avoid omitted variable bias, inform development of new intervention strategies, and support mediating and moderating analyses. Based on a life course model and a whole child perspective, this article suggests constructs in the domains of child health, emotional/psychological development, educational achievement/attainment, social behavior, and social relationships. Four critical constructs are highlighted: self-regulation, agency/motivation, persistence/diligence, and executive functioning. Other constructs that are currently measured need to be retained, including social skills, positive relationships, activities, positive behaviors, academic self-efficacy, educational engagement, and internalizing/emotional well-being. Examples of measures that are substantively and psychometrically robust are provided.

    Full Text Available Service-learning pedagogy allows social work educators to create meaningful learning opportunities for students and better prepare them for practicum, while at the same time, meeting a community need. This paper outlines the relevance of incorporating service-learning into the social work curriculum, specifically the human behavior and the social environment (HBSE area. Using Bloom’s taxonomy as a guide, the authors propose how the CSWE competencies and practice behaviors specific to HBSE may be assessed using service-learning pedagogy. An example is reviewed to illustrate how service-learning can assist faculty and students achieve the HBSE competencies and practice behaviors. Finally, implications for service-learning as a pedagogical strategy for social work education are discussed.

    A number of pediatric collaborative improvement networks have demonstrated improved care and outcomes for children. Regionally, Cincinnati Children's Hospital Medical Center Physician Hospital Organization has sustained key asthma processes, substantially increased the percentage of their asthma population receiving "perfect care," and implemented an innovative pay-for-performance program with a large commercial payor based on asthma performance measures. The California Perinatal Quality Care Collaborative uses its outcomes database to improve care for infants in California NICUs. It has achieved reductions in central line-associated blood stream infections (CLABSI), increased breast-milk feeding rates at hospital discharge, and is now working to improve delivery room management. Solutions for Patient Safety (SPS) has achieved significant improvements in adverse drug events and surgical site infections across all 8 Ohio children's hospitals, with 7700 fewer children harmed and >$11.8 million in avoided costs. SPS is now expanding nationally, aiming to eliminate all events of serious harm at children's hospitals. National collaborative networks include ImproveCareNow, which aims to improve care and outcomes for children with inflammatory bowel disease. Reliable adherence to Model Care Guidelines has produced improved remission rates without using new medications and a significant increase in the proportion of Crohn disease patients not taking prednisone. Data-driven collaboratives of the Children's Hospital Association Quality Transformation Network initially focused on CLABSI in PICUs. By September 2011, they had prevented an estimated 2964 CLABSI, saving 355 lives and $103,722,423. Subsequent improvement efforts include CLABSI reductions in additional settings and populations.

  19. Achieving true sustainability of zoo populations.

    2013-01-01

    For the last 30 years, cooperative management of irreplaceable animal populations in zoos and aquariums has focused primarily on the goal of minimizing genetic decay within defined time frames, and large advances have been made in technologies to optimize genetic management of closed populations. However, recent analyses have shown that most zoo programs are not projected to meet their stated goals. This has been described as a lack of achieving "sustainability" of the populations, yet by definition a goal of managed decay is not a plan for sustainability. True sustainability requires management of the resource in manner that does not deplete its value for the future. Achieving such sustainability for many managed populations may require changing from managing isolated populations to managing populations that are part of a broader metapopulation, with carefully considered exchange between populations across a spectrum of ex situ to in situ. Managing zoo populations as components of comprehensive conservation strategies for the species will require research on determinants of various kinds of genetic, physiological, behavioral, and morphological variation and their roles in population viability, development of an array of management techniques and tools, training of population managers in metapopulation management and integrated conservation planning, and projections of impacts of management strategies on the viability of the captive populations and all populations that are interactively managed or affected. Such a shift in goals and methods would result in zoo population management being an ongoing part of species conservation rather than short-term or isolated from species conservation.

    Understanding the stages of growth, saturation and transition is the first step to setting meaningful career goals. While this concept is fairly new in dentistry, it is not new in other commercial enterprises. Business managers and owners have known for decades that growth stagnates after a period of time. At that point, a new infusion of energy and a reformation of the business's objectives and methods are needed to launch forward into the next phase of growth. Transition management in dentistry represents periods of growth that are followed by saturation and a comparatively rapid changeover to a new practice form. Saturation occurs when the clinical capacity of a practice is exceeded by the needs of a growing patient base. The key transitions in the career of a dentist are those from school to practising, and practising to retirement. A great number of dentists (due to low motivation, the comfort level or poor management skills) never reach the saturation point during their practising career. For these dentists, starting out and retirement are the only transitions that will ever apply to them. Dentists evaluating transition options must first identify which career stage they belong to since their objectives will be different at each stage. Dentists in the growth phase should focus on practice management and achieving saturation before attempting a transition. Since transitions like start-up, retirement, partnerships, associateships and buy-ins have pivotal roles in the life cycle of a practice, transitions must be managed carefully to achieve successful results.(ABSTRACT TRUNCATED AT 250 WORDS)

    A healthcare system has been the most important priority for all governments worldwide. Biotechnology products have affected the promotion of health care over the last thirty years. During the last several decades, Iran has achieved significant success in extending healthcare to the rural areas and in reducing the rates of infant mortality and increasing population growth. Biomedical technology as a converging technology is considered a helpful tool to fulfill the Iranian healthcare missions. The number of biotechnology products has reached 148 in 2012. The total sales have increased to 98 billion USD without considering vaccines and plasma derived proteins in 2012. Iran is one of the leading countries in the Middle East and North Africa in the area of Medical biotechnology. The number of biotechnology medicines launched in Iran is 13 products until 2012. More than 15 products are in pipelines now. Manufacturers are expecting to receive the market release for more than 8 products by the end of 2012. Considering this information, Iran will lead the biotechnology products especially in area of biosimilars in Asia after India in next three years. The present review will discuss leading policy, decision makers' role, human resource developing system and industry development in medical biotechnology.

    Emergency responses require the coordination of first responders to assess the condition of victims, stabilize their condition, and transport them to hospitals based on the severity of their injuries. WIISARD is a system designed to facilitate the collection of medical information and its reliable dissemination during emergency responses. A key challenge in WIISARD is to deliver data with high reliability as first responders move and operate in a dynamic radio environment fraught with frequent network disconnections. The initial WIISARD system employed a client-server architecture and an ad-hoc routing protocol was used to exchange data. The system had low reliability when deployed during emergency drills. In this paper, we identify the underlying causes of unreliability and propose a novel peer-to-peer architecture that in combination with a gossip-based communication protocol achieves high reliability. Empirical studies show that compared to the initial WIISARD system, the redesigned system improves reliability by as much as 37% while reducing the number of transmitted packets by 23%.

    Direct Drive, widely used on Omega, provides high coupling energy and core temperatures per drive. NIF's much higher power offers a prospect for attaining hotter, larger cores enabling higher fidelity burn experiments. To use Omega's knowledge on NIF involves understanding the differences between PDD and SDD. Achieving symmetric implosions in PDD is essential for attaining high temperatures and neutron yields. LANL team tested laser cone-power tuning designs done with rad-hydro code HYDRA utilizing a flux-limited heat conduction (FLHC) model on NIF and Omega. Both campaigns produced symmetric implosions in PDD configuration. Omega campaign confirmed P2 tunability that was in agreement with the simulations, while in experiments on NIF |P2| role of LPI effects which are often left out in simulations. We found that when I > 1015W/cm2 on NIF, FLHC model in HYDRA was insufficient to accurately predict symmetry, bright equatorial self-emission band, and enhanced hot electron population. We were able to account for these effects by including CBET and non-local heat transfer models. Here we present out analysis of PDD symmetry data. We report on hot electron and CBET effects and assess our ability to model them with rad-hydro codes. We will also discuss laser intensity limits in PDD.

    Broadened recruitment to higher education is on the agenda in many countries, and it is also widely recognized that the number of dyslexic students entering higher education is increasing. In Sweden, as in many other European countries, higher education institutions are required to accommodate students with dyslexia. The present study focuses on the study outcome for 50 students with diagnosed dyslexia, mainly in teacher education and nurses' training, at three universities in Northern Sweden. The students trusted their own ability to find information on the Internet but mistrusted their own abilities in reading course books and articles in English and in taking notes. The mean rate of study was 23.5 European Credit Transfer and Accumulation System credits per semester, which is slightly below the national baseline of 26.7. The results show that more than half of the students are examined at a normal rate of study but that about one fifth have a very low rate of study. Messages Most students with dyslexia can compensate for their reading problems. Taking notes during lessons and reading in foreign language may be especially difficult for students with dyslexia. Diagnoses should distinguish between reading comprehension and word decoding. More than half of the students with dyslexia can achieve at a normal rate of study. One-fifth of the students with dyslexia may need a longer period of study than other students.

    First Millennium Development Goal states the target of "Halving hunger by 2015". Sadly, the recent statistics for India present a very gloomy picture. India currently has the largest number of undernourished people in the world and this is in spite of the fact that it has made substantial progress in health determinants over the past decades and ranks second worldwide in farm output. The causes of existing food insecurity can be better viewed under three concepts namely the: 'traditional concept' which includes factors such as unavailability of food and poor purchasing capacity; 'socio-demographic concept' which includes illiteracy, unemployment, overcrowding, poor environmental conditions and gender bias; 'politico-developmental concept' comprising of factors such as lack of intersectoral coordination and political will, poorly monitored nutritional programmes and inadequate public food distribution system. If the Millennium Development Goal is to be achieved by 2015, efforts to improve food and nutrition security have to increase considerably. Priority has to be assigned to agriculture and rural development along with promoting women empowerment, ensuring sustainable employment and improving environmental conditions (water, sanitation and hygiene). As the problem is multi-factorial, so the solution needs to be multi-sectoral.

    This study investigated the influence of achievement motivation (Nach) on how individuals perceive an evaluative competition situation, whether they prefer to perform in this type of setting, and whether they seek the inherent appraisal information regarding their motoric competence. Specifically, perceived threat to self esteem was examined as indicated by state anxiety responses and measured by the Competitive Short Form of the Spielberger State Anxiety Inventory. State anxiety was assessed at rest, while performing a motor task alone in a nonevaluative setting, and during competition against an equal ability opponent. Situation perference and information seeking behavior were assessed at the conclusion of the closely paced competition. Subjects were asked whether they had perferred performing in the noncompetition or competition situation and were given the opportunity to select the relative ability level of a future opponent. As predicted, the major findings indicated that high Nach males experienced less threat during competition than low Nach males. Further, more high than low Nach individuals perferred the competition situation to the noncompetition situation and sought the evaluative ability information to a greater extent by choosing opponents of equal or greater relative ability for a future hypothetical competition.

    Research on the biomedical applications of low temperature plasmas started with small scale experiments that were simply aimed at discovering what happens to biological cells when exposed to the chemically rich environment of plasma. These early experiments took place in the mid to late 1990s. As interest in this multidisciplinary field dramatically rose, various engineering and physics groups collaborated with biologists and medical experts to investigate the use of plasma technology as a basis for innovative medical approaches to cure various diseases. However, many questions concerning the fundamental mechanisms involved in cell-plasma interaction remained unanswered. As a result various workshops were organized to gather the diverse research community in the field of plasma medicine in order to have a fruitful exchange of ideas regarding the scientific challenges that needed to be surmounted to advance and expand the field's knowledge base. The present GEC workshop continues this important tradition of scientific cooperation since there is still a significant lack of understanding of many of the biochemical and molecular pathways that come into play when biological cells are exposed to plasmas. In this talk, first background information on the various plasma devices developed in our institute will be presented. This will be followed by a summary of our work on the effects of plasmas on prokaryotic and eukaryotic cells. The talk will be concluded by presenting our vision of the future of the field and an outline of the main challenges that need to be overcome if practical medical applications are to be achieved.

    Schmitt, Carrie Catherine

    Uncontrollable hemorrhage is significant cause of preventable death in the military and civilian setting. Hemostatic wound dressings have been created in an attempt to rectify this problem, but none currently on the market are highly effective at controlling hemorrhage resulting in a need for an effective hemostatic wound dressing. This study investigated the effects of gold, silver, and silica nanoparticles on blood coagulation time in order to determine if nanoparticle incorporation into a hemostatic wound dressing would effectively achieve hemostasis. Gold, silver, and silica nanoparticles were experimented with two different ex vivo studies to determine their effects on coagulation. A modified Lee White Method and a rotational viscometer were utilized to assess the nanoparticles ability to clot blood. Results obtained from the modified Lee White Method proved inconsistent and inconclusive demonstrating a need for improved testing methods. Results acquired from viscometer testing demonstrated that silica was effective in decreasing coagulation time indicating its potential use as a hemostatic agent and its prospective incorporation into a hemostatic wound dressing.

    The optimum time students should spend on homework has been widely researched although the results are far from unanimous. The main objective of this research is to analyze how homework assignment strategies in schools affect students' academic performance and the differences in students' time spent on homework. Participants were a representative sample of Spanish adolescents (N = 26,543) with a mean age of 14.4 (±0.75), 49.7% girls. A test battery was used to measure academic performance in four subjects: Spanish, Mathematics, Science, and Citizenship. A questionnaire allowed the measurement of the indicators used for the description of homework and control variables. Two three-level hierarchical-linear models (student, school, autonomous community) were produced for each subject being evaluated. The relationship between academic results and homework time is negative at the individual level but positive at school level. An increase in the amount of homework a school assigns is associated with an increase in the differences in student time spent on homework. An optimum amount of homework is proposed which schools should assign to maximize gains in achievement for students overall.

    2014-01-01

    The first protein crystallography group in Switzerland was installed at the Biozentrum of the University of Basel approximately 40 years ago. Since then protein crystallography has grown and matured remarkably and is now established in the molecular biology, biochemistry or biological medicine departments of most major Swiss Universities as well as in the pharmaceutical industry and in biotech startup companies. Swiss X-ray biocrystallography groups have made remarkable contributions from the beginning and have brought Switzerland to the forefront in biostructural research during the last 5 to 10 years. Switzerland has now a leading position in the areas of supramolecular complexes, membrane proteins and structure-based drug design in pharmaceutical and biotech industries. Protein crystallography on the outer membrane protein ompF as well as the development of the lipidic cubic phase crystallization methodology has been pioneered at the Biozentrum. The latter found its somewhat late recognition through the recent explosion in structure determinations of the seven transmembrane helix G-coupled receptors. Highlights from Swiss structural biology groups in the field of supramolecular complexes include the structures of ribosomal particles, of the nucleosome and the pilus assembly complex of uropathogenic E. coli. On the membrane protein side advances in the field of ABC transporters and ion channels are world-recognized achievements of Swiss structural biology. Dedicated laboratories at many academic and industrial institutions, their current research programs, the availability of excellent infrastructure and the continuing efforts to build new facilities such as the SwissFEL indicate an even brighter future for structural biology in Switzerland.

  9. ACHIEVING "DECENT WORK" IN SOUTH AFRICA?

    Full Text Available The fundamental goal of the International Labour Organisation is the achievement of decent and productive work for both women and men in conditions of freedom, equity, security and human dignity. The South African government has pledged its commitment to the attainment of decent work and sustainable livelihoods for all workers and has undertaken to mainstream decent work imperatives into national development strategies. The four strategic objectives of decent work as identified by the ILO are: i the promotion of standards and rights at work, to ensure that worker's constitutionally protected rights to dignity, equality and fair labour practices, amongst others, are safeguarded by appropriate legal frameworks; (ii the promotion of employment creation and income opportunities, with the goal being not just the creation of jobs but the creation of jobs of acceptable quality; (iii the provision and improvement of social protection and social security, which are regarded as fundamental to the alleviation of poverty, inequality and the burden of care responsibilities; and (iv the promotion of social dialogue and tripartism. This article considers the progress made towards the attainment of these decent work objectives in South Africa, using five statistical indicators to measure such progress namely: (i employment opportunities; (ii adequate earnings and productive work; (iii stability and security of work; (iv social protection; and (v social dialogue and workplace relations. It concludes that high levels of unemployment and a weakened economy in South Africa have given rise to a growing informal sector and an increase in unacceptable working conditions and exploitation. The rights of workers in the formal sector have not filtered down to those in the informal sector, who remains vulnerable and unrepresented. Job creation initiatives have been undermined by the global recession and infrastructural shortcomings and ambitious governmental targets appear

  10. Telemedicine and diabetes: achievements and prospects.

    Health authorities currently have high expectations for telemedicine (TM), as it addresses several major challenges: to improve access to healthcare (especially for patients in underserved or remote areas); to overcome the scarcity of specialists faced with epidemic disease; and to reduce the costs of healthcare while improving quality. The aims of TM in the field of diabetes differ according to the type of diabetes. In type 1 diabetes (T1DM) associated with complex insulin regimens, the goal of TM is to help patients achieve better control of their blood glucose levels through accurate adjustment of insulin doses. In type 2 diabetes (T2DM), while therapeutic adjustments may be necessary, improvement in blood glucose control is based primarily on behavioural changes (reduced calorie and carbohydrate intakes, increased physical activity). Many TM studies focusing on management of blood glucose levels have been published, but most failed to demonstrate any superiority of TM vs traditional care. While previously published meta-analyses have shown a slight advantage at best for TM, these meta-analyses included a mix of studies of varying durations and different populations (both T1DM and T2DM patients, adults and children), and tested systems of inconsistent quality. Studies published to date on TM suggest two currently promising approaches. First, handheld communicating devices, such as smartphones, loaded with software to apply physicians' prescriptions, have been shown to improve glycaemic control. These systems provide immediate assistance to the patient (such as insulin-dose calculation and food choice optimization at meals), and all data stored in the smartphone can be transmitted to authorized caregivers, enabling remote monitoring and even teleconsultation. These systems, initially developed for T1DM, appear to offer many possibilities for T2DM, too. Second, systems combining an interactive Internet system (or a mobile phone coupled to a remote server) with a

    2007-09-01

    This study investigated the relationship between school racial climate and students' self-reports of academic and discipline outcomes, including whether racial climate mediated and/or moderated the relationship between race and outcomes. Using the Racial Climate Survey-High School Version (M. Aber et al., unpublished), data were gathered from African American (n = 382) and European American students (n = 1456) regarding their perceptions of racial climate. About 18% of the respondents were low-income and approximately 50% were male. Positive perceptions of the racial climate were associated with higher student achievement and fewer discipline problems. Further, race moderated the relationship between racial climate and both achievement and discipline outcomes. Finally, racial differences in students' grades and discipline outcomes were associated with differences in perceptions of racial climate. Results suggest careful attention should be given to the racial climate of secondary schools, particularly for adolescents who perceive schools as unfair.

  12. Achievable field strength in reverberation chambers

    Directory of Open Access Journals (Sweden)

    N. Eulig

    2003-01-01

    automotive systems, immunity tests with field strengths of several 100 V/m are necessary. Such high field strengths can only be generated with substantial RF power and therefore expensive amplifiers if the test is performed in an environment with plane waves. Due to resonance effects in mode-stirred chambers, comparable values of the field strength can there be obtained with significantly less power. In these chambers the field strength declines with increasing volume for a constant input power. As an ideal testing environment a mode-stirred chamber should also work at low frequencies which requires a large volume, however. Hence there is a contradiction between generating high level field strengths on the one hand and obtaining a lowest usable frequency of several 10 MHz on the other. This relativizes the advantage of generating high field strengths with less power if the chamber is supposed to work down to low frequencies. This article deals with the field strengths that can be obtained in mode-stirred chambers with a certain size. Data of different mode-stirred chambers are compared. From this a frequency limit can be derived, above which the use a mode-stirred chamber for achieving high field strengths seems meaningful only.

  13. Schoolbook Texts: Behavioral Achievement Priming in Math and Language.

    Engeser, Stefan; Baumann, Nicola; Baum, Ingrid

    2016-01-01

    Prior research found reliable and considerably strong effects of semantic achievement primes on subsequent performance. In order to simulate a more natural priming condition to better understand the practical relevance of semantic achievement priming effects, running texts of schoolbook excerpts with and without achievement primes were used as priming stimuli. Additionally, we manipulated the achievement context; some subjects received no feedback about their achievement and others received feedback according to a social or individual reference norm. As expected, we found a reliable (albeit small) positive behavioral priming effect of semantic achievement primes on achievement in math (Experiment 1) and language tasks (Experiment 2). Feedback moderated the behavioral priming effect less consistently than we expected. The implication that achievement primes in schoolbooks can foster performance is discussed along with general theoretical implications.

  6. A causal analysis relating previous achievement, attitudes, discourse, and intervention to achievement in biology and chemistry

    Science.gov (United States)

    Gooding, C. Thomas; Swift, J. Nathan; Schell, Robert E.; Swift, Patricia R.; McCroskery, James H.

    This study described the relationship of 38 variates to achievement in high school biology and chemistry classes. Forty-four teachers prepared audio tape recordings of discussions throughout a nine-month period. Equal-sized groups received treatment consisting of wait time feedback and/or supportive intervention, a form of peer coaching. Other variables were initial measures, which included the variates of class size and previous science grade, pre- and posttest scores on student attitudes and perceptions, and prediscourse and discourse analyses, which included the variates of wait times, actions, and response durations. While previous research has shown that wait time feedback and supportive intervention are effective means of changing teacher behavior, the results of the present study revealed that previous student achievement and the attitudes of students accounted for 70% of the variation in the final examination scores (New York State Regents) on the basis of only the first three weeks of data collection on the variables assessed. Generally, little emphasis on higher-level thinking, wait time, or problem solving was found at the beginning of the school year, and only minimal changes resulted from the application of the treatment variables. Pressures for content coverage and preparation for externally imposed statewide examinations that emphasize memory-level learning augured against the changes that the independent variables were designed to produce.

    2012-11-01

    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, pmathematics 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.

    2008-10-01

    This study examined how values related to achievement goals and individual-oriented and social-oriented achievement motivations among secondary school students in China (N = 355) and Indonesia (N = 356). Statistical comparisons showed the Chinese students endorsed more strongly than the Indonesian students on self-direction and hedonism values, individual-oriented achievement motivation, and mastery-approach goals. Conversely, the Indonesian students endorsed more strongly than their Chinese counterparts on security, conformity, tradition, universalism and achievement values, social-oriented achievement motivation, and performance-approach and mastery-avoidance goals. Values explained a significant amount of the variance in almost all of the dimensions of motivation. Etic and emic relationships between values and achievement motivations were found.

    Full Text Available This research has been investigating one of the most contemporary approaches of achievement motivation - Achievement Goal Theory, which uses the construct of achievement goals. The construct of achievement goals involves three types of achievement goals: mastery goals, performance approach goals and performance avoidance goals. The main goal of the research was to examine correlation between perfectionism and its aspects with particular types of achievement goals. Also, the goal was to investigate the difference concerning gender regarding the achievement goals. The sample consisted of 200 senior year high school participants. The following instruments were used: Multi-dimensional scale of perfectionism (MSP and Test of achievement goals (TCP. The research results indicate that there is significant positive correlation between: perfectionism with performance approach goals and performance avoidance goals, concern over mistakes and parental expectations with performance approach goals and performance avoidance goals, personal standards and organization with mastery goals and performance approach goals, parental criticism and doubts about action with performance avoidance goals. Significant negative correlation was found between parental criticism and mastery goals. The results concerning the second goal indicates the female subjects have higher average scores in mastery goals.

  2. Female teachers' math anxiety affects girls' math achievement.

    Science.gov (United States)

    Beilock, Sian L; Gunderson, Elizabeth A; Ramirez, Gerardo; Levine, Susan C

    2010-02-02

    People's fear and anxiety about doing math--over and above actual math ability--can be an impediment to their math achievement. We show that when the math-anxious individuals are female elementary school teachers, their math anxiety carries negative consequences for the math achievement of their female students. Early elementary school teachers in the United States are almost exclusively female (>90%), and we provide evidence that these female teachers' anxieties relate to girls' math achievement via girls' beliefs about who is good at math. First- and second-grade female teachers completed measures of math anxiety. The math achievement of the students in these teachers' classrooms was also assessed. There was no relation between a teacher's math anxiety and her students' math achievement at the beginning of the school year. By the school year's end, however, the more anxious teachers were about math, the more likely girls (but not boys) were to endorse the commonly held stereotype that "boys are good at math, and girls are good at reading" and the lower these girls' math achievement. Indeed, by the end of the school year, girls who endorsed this stereotype had significantly worse math achievement than girls who did not and than boys overall. In early elementary school, where the teachers are almost all female, teachers' math anxiety carries consequences for girls' math achievement by influencing girls' beliefs about who is good at math.

  15. Optional online quizzes: College student use and relationship to achievement

    Directory of Open Access Journals (Sweden)

    Genevieve Marie Johnson

    2006-02-01

    Full Text Available Online practice tests and quizzes are commonly available to higher education students. The extent of student use of such study tools and the relationship of use to achievement, however, have not been fully investigated. One hundred twelve college students were encouraged to use optional online quizzes in preparation for proctored examinations. In-class examinations included multiple choice items that assessed four cognitive domains: factual, application, comprehension, and conceptual. In general, few students made extensive use of the optional online quizzes. Analysis revealed that student use of online quizzes was associated with increased academic achievement, although it was not clear if quiz use caused achievement or achievement caused quiz use. Short-answer and true-false online quiz items were differentially associated with measures of academic achievement, suggesting that cognitive processing differed across item format. Implications for further research are provided.

    2006-01-01

    Over the past 25 years, achievement goal theory has emerged as one of the most prominent theories of achievement motivation. This chapter uses an achievement goal framework to examine the influence of classroom and school environments on students' academic motivation and achievement. Considerable evidence suggests that elementary and secondary students show the most positive motivation and learning patterns when their school settings emphasize mastery, understanding, and improving skills and knowledge. Whereas school environments that are focused on demonstrating high ability and competing for grades can increase the academic performance of some students, research suggests that many young people experience diminished motivation under these conditions. The implications of achievement goal theory for examining the impact of school reform are discussed.

    Cragg, Lucy; Keeble, Sarah; Richardson, Sophie; Roome, Hannah E; Gilmore, Camilla

    2017-02-08

    Achievement in mathematics is predicted by an individual's domain-specific factual knowledge, procedural skill and conceptual understanding as well as domain-general executive function skills. In this study we investigated the extent to which executive function skills contribute to these three components of mathematical knowledge, whether this mediates the relationship between executive functions and overall mathematics achievement, and if these relationships change with age. Two hundred and ninety-three participants aged between 8 and 25years completed a large battery of mathematics and executive function tests. Domain-specific skills partially mediated the relationship between executive functions and mathematics achievement: Inhibitory control within the numerical domain was associated with factual knowledge and procedural skill, which in turn was associated with mathematical achievement. Working memory contributed to mathematics achievement indirectly through factual knowledge, procedural skill and, to a lesser extent, conceptual understanding. There remained a substantial direct pathway between working memory and mathematics achievement however, which may reflect the role of working memory in identifying and constructing problem representations. These relationships were remarkably stable from 8years through to young adulthood. Our findings help to refine existing multi-component frameworks of mathematics and understand the mechanisms by which executive functions support mathematics achievement.

  4. Academic resilience in education: the role of achievement goal orientations

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Introduction: In the past 2 decades, research findings established achievement goal theory as a powerful framework for conceptualizing difference in the quality of student’s engagement, persistence on task, and academic resilience. So the present study examined the relationship between achievement goal orientations and academic resilience. Method: Participants were 606 students (307 girls and 297 boys selected from Shiraz high schools. They completed the Achievement Goals Questionnaire and Youth development Module Scale (RYDM. To analyze the data, the relationships between variables were examined, using Pearson product– moment correlations. Also simulanteous multiple regression was performed to investigate the prediction of academic resilience by achievement goal orientations. To examine the reliability and the validity of measures Cronbach alpha coefficient and factor analysis method were applied, respectively. Results: Simultaneous multiple regression of achievement goal orientations on academic resilience showed that “mastery-approach” was a significant positive predictor of the “home care/high” and “peer care” subscales. Also, “performance-approach” was a significant, positive predictor of “home care/ high”, and “school/community meaningful” was predicted by “performanceavoidance” positively. Conclusion: According to the findings, it seems that achievement goal orientation has a critical role in students’ academic achievement. Implications of the results are discussed in more details.

    2010-01-01

    In a polyomino set (1,2)-achievement game the maker and the breaker alternately mark one and two previously unmarked cells respectively. The maker's goal is to mark a set of cells congruent to one of a given set of polyominoes. The breaker tries to prevent the maker from achieving his goal. The teams of polyominoes for which the maker has a winning strategy is determined up to size 4. In set achievement games, it is natural to study infinitely large polyominoes. This enables the construction of super winners that characterize all winning teams up to a certain size.

    One thousand seven hundred and sixty six secondary school students in Hong Kong participated in the present study, in which the relationship among mathematics achievement, affective variables and home background was investigated. It was found that mathematics achievement was most closely related with self-concept, academic self-concept and attitudes towards mathematics. Self- and parental expectations were the most influential factors to these affective variables. It was also found that Hong Kong students spent, on the average, over 33% of homework time on mathematics homework. The time spend on homework, however, did not exhibit significant correlation with mathematics achievement.

  8. Physics in canadian secondary schools: Intentions, perceptions, and achievement

    Science.gov (United States)

    Finegold, Menahem; Raphael, Dennis

    This article examines secondary-school physics teaching with respect to three levels of curriculum. These are the curriculum as designed by educational authorities and intended for school guidance, as perceived by teachers and translated into classroom practice, and as internalized by students and expressed by achievement on physics tests. In keeping with international usage we refer to these levels of curriculum as the intended, the translated and the achieved. The article is based upon the analysis of curriculum documents and guidelines, teacher assessments of opportunity provided students to learn, and student achievement on a comprehensive physics test. The context for analysis is provided by an ongoing international study of science education in which some 30 participating countries analyze the three curriculum levels and attempt to draw conclusions concerning possible relationships among them. The article reports limited but nevertheless significant relationships found among intentions, translations, and achievement in the teaching of physics in Canadian secondary schools.

    Full Text Available Achievement gaps between immigrant and native students indicate failure to assure educational equity in the majority of countries assessed by the Programme for International Student Assessment in 2009 (PISA, 2009. The present article explains disparate achievement results in Europe, first testing the hypothesis of old and new democracies. In further contextualisation of the achievement results, the analysis seeks explanations beyond the common education system explanatory model. Specifically, the article considers results from Croatia, Serbia and Slovenia, highlighting the significance of language distance between native and immigrant students as well as migration regimes as important factors in creating or reducing the achievement gap between native and immigrant students. Evidence has been found that immigrant students score worse in countries with guest labour immigration regimes than in the countries with large scale forced immigration of people of the same ethnic (linguistic origin.

    2016-01-01

    Full Text Available In the framework of Positive Organizational Behavior, the construct of Psychological Capital identifies four psychological capacities that affect motivation and performance in the workplace: self-efficacy, hope, optimism and resilience. Emotional Intelligence, then, addresses self-regulatory processes of emotions and motivation that enable people to make adjustments to achieve individual, group, and organizational goals; Emotional Intelligence is strongly correlated with individual advancement and success in an organizational setting and with individual performance. Moreover, Emotional Intelligence is considered an antecedent to resilience. The present study aims to investigate the role of resilience and emotional intelligence in achievement motivation, verifying if emotional intelligence mediates the relationship among resilience and achievement motivation. Participants are 488 Italian workers, aged between 18 and 55 years. The findings confirm the significant role played by emotional intelligence on resilience and on motivation to achievement.

    Full Text Available The prime purpose of this study is to investigate the effect of computer animation supported biology education upon students’ academic achievement. The study was participated by 97 pre service teachers studying in the first year of university. The data were collected by “Cell Achievement Test” There were control and experimental groups formed and the experimental group was taught with computer animations related with diffusion, osmosis, active transport, protein synthesis, mitosis and meiosis phenomena taking place in cell while the control group was taught with traditional method based on question and answer process. The data obtained were evaluated by t- test and represented by tables and graphs. The results of the study indicated significant differences between the academic achievements of control and experimental groups. The difference is in the favor of the experimental group which revealed the fact the computer animations caused a significant increase in the academic achievements of the students.

  16. Impact of Chemistry Teachers' Knowledge and Practices on Student Achievement

    2008-10-01

    Professional development programs promoting inquiry-based teaching are challenged with providing teachers content knowledge and using pedagogical approaches that model standards based instruction. Inquiry practices are also important for undergraduate students. This paper focuses on the evaluation of an extensive professional development program for chemistry teachers that included chemistry content tests for students and the teachers and the impact of undergraduate research experiences on college students' attitudes towards chemistry. Baseline results for the students showed that there were no gender differences on the achievement test but white students scored significantly higher than non-white students. However, parent/adult involvement with chemistry homework and projects, was a significant negative predictor of 11th grade students' test chemistry achievement score. This paper will focus on students' achievement and attitude results for teachers who are mid-way through the program providing evidence that on-going, sustained professional development in content and pedagogy is critical for improving students' science achievement.

    Rich, Steve Anthony

    The purpose of this study was to investigate the relationship between teaching elementary science outdoors and student achievement on science standards. The study also considered student attitudes toward learning outdoors in the schoolyard and their achievement on a science standard appropriate for teaching outdoors. The seminal work in the field (Louv, 2005) created the phrase "nature deficit disorder" to describe the condition of children that spend little time outdoors learning from and playing in nature. Five fourth grade classes took part in outdoor instruction on particular standards after taking an attitudinal survey on learning outdoors and a pretest on the science content. Both measures were repeated after outdoor instruction. The hypotheses of the study were that students receiving outdoor instruction demonstrate improved science achievement and that student attitudes towards learning science outdoors has a significant impact on student achievement related to a science standard. The results of the study indicate a gain in student achievement followed the outdoor science lessons, allowing the research to accept the hypothesis as valid. However, the study found that student attitude toward learning science outdoors was not a significant factor in predicting gains in student achievement.

    Full Text Available This research aims to find out (1 whether there is an influence between student’s achievements of learning violin toward their emotional intelligence, (2 whether there is a correlation between student’s achievement of learning violin and their emotional intelligence, and (3 how much contribution of student’s achievement of learning violin to their emotional intelligence. It is a qualitative research which is defined as a research method based on positivism philosophy which is used to study particular sample and population. The sample and population are drawn randomly using research instruments to collect data, and the data are analyzed statistically. This aims to examine the hypothesis defined. The finding shows that there is a significant influence between student’s achievement of learning violin and their emotional intelligence about 76.1%, while the rest of it 23.9% is influenced by other factors which are not studied in this research. It proves that learning violin influences student’s emotional intelligence very much and emotional intelligence is influential in increasing student’s achievement. From the data, it shows that most of the students participating in violin extracurricular are able to increase their learning achievement.

    This study is designed to investigate friend influence over mathematical reasoning in a sample of 374 children in 187 same-sex friend dyads (184 girls in 92 friendships; 190 boys in 95 friendships). Participants completed surveys that measured mathematical reasoning in the 3rd grade (approximately 9 years old) and one year later in the 4th grade (approximately 10 years old). Analyses designed for dyadic data (i.e., longitudinal Actor-Partner Interdependence Models) indicated that higher achieving friends influenced the mathematical reasoning of lower achieving friends, but not the reverse. Specifically, greater initial levels of mathematical reasoning among higher achieving partners in the 3rd grade predicted greater increases in mathematical reasoning from 3rd grade to 4th grade among lower achieving partners. These effects held after controlling for peer acceptance and rejection, task avoidance, interest in mathematics, maternal support for homework, parental education, length of the friendship, and friendship group norms on mathematical reasoning.

    Homework is a debated issue in society and its relationship with academic achievement has been deeply studied in the last years. Nowadays, schools are multicultural stages in which students from different cultures and ethnicities work together. In this sense, the present study aims to compare homework involvement and academic achievement in a sample of native and immigrant students, as well as to study immigrant students' relationship between homework involvement and Math achievement. The sample included 1328 students, 10-16 years old from Spanish families (85.6%) or immigrant students or students of immigrant origin (14.4%) from South America, Europe, Africa, and Asia. The study was developed considering three informants: elementary and secondary students, their parents and their teachers. Results showed higher involvement in homework in native students than in immigrant. Between immigrants students, those who are more involved in homework have better academic achievement in Math at secondary grades. There weren't found gender differences on homework involvement, but age differences were reported. Immigrant students are less involved in homework at secondary grades that students in elementary grades. The study highlights the relevance of homework involvement in academic achievement in immigrant students.

    2016-08-02

    Two largely separate bodies of empirical research have shown that academic achievement is influenced by structural factors, such as socioeconomic background, and psychological factors, such as students' beliefs about their abilities. In this research, we use a nationwide sample of high school students from Chile to investigate how these factors interact on a systemic level. Confirming prior research, we find that family income is a strong predictor of achievement. Extending prior research, we find that a growth mindset (the belief that intelligence is not fixed and can be developed) is a comparably strong predictor of achievement and that it exhibits a positive relationship with achievement across all of the socioeconomic strata in the country. Furthermore, we find that students from lower-income families were less likely to hold a growth mindset than their wealthier peers, but those who did hold a growth mindset were appreciably buffered against the deleterious effects of poverty on achievement: students in the lowest 10th percentile of family income who exhibited a growth mindset showed academic performance as high as that of fixed mindset students from the 80th income percentile. These results suggest that students' mindsets may temper or exacerbate the effects of economic disadvantage on a systemic level.

    Impairments in executive function have been documented in school-age children with mathematical learning difficulties. However, the utility and specificity of preschool executive function abilities in predicting later mathematical achievement are poorly understood. This study examined linkages between children's developing executive function abilities at age 4 and children's subsequent achievement in mathematics at age 6, 1 year after school entry. The study sample consisted of a regionally representative cohort of 104 children followed prospectively from ages 2 to 6 years. At age 4, children completed a battery of executive function tasks that assessed planning, set shifting, and inhibitory control. Teachers completed the preschool version of the Behavior Rating Inventory of Executive Function. Clinical and classroom measures of children's mathematical achievement were collected at age 6. Results showed that children's performance on set shifting, inhibitory control, and general executive behavior measures during the preschool period accounted for substantial variability in children's early mathematical achievement at school. These associations persisted even after individual differences in general cognitive ability and reading achievement were taken into account. Findings suggest that early measures of executive function may be useful in identifying children who may experience difficulties learning mathematical skills and concepts. They also suggest that the scaffolding of these executive skills could potentially be a useful additional component in early mathematics education.

    In two independent datasets with 1872 elementary-aged children in 83 classrooms, Studies 1 and 2 examined the role of classroom context in moderating the relationship between child ethnicity and teacher expectations. For Study 1 overall and Study 2 mixed-grade classrooms, in ethnically diverse classrooms where students reported high levels of differential teacher treatment (PDT) towards high and low achieving students, teacher expectations of European American and Asian American students were between .75 and 1.00 standard deviations higher than teacher expectations of African American and Latino students with similar records of achievement. In highly diverse low-PDT classrooms in Study 1 and highly diverse low-PDT mixed-grade classrooms in Study 2, teachers held similar expectations for all students with similar records of achievement. Study 3 estimated the contribution of teacher expectations to the year-end ethnic achievement gap in high- and low-bias classrooms. In high-bias classrooms, teacher expectancy effects accounted for an average of .29 and up to .38 standard deviations of the year-end ethnic achievement gap.

    This study addressed a prevalence of low achievement in science courses in an urban school district in Georgia. National leaders and educators have identified the improvement of science proficiency as critical to the future of American industry. The purpose of this study was to examine parent involvement in this school district and its contribution to the academic achievement of successful science students. Social capital theory guided this study by suggesting that students achieve best when investments are made into their academic and social development. A collective case study qualitative research design was used to interview 9 parent participants at 2 elementary schools whose children scored in the exceeds category on the Science CRCT. The research questions focused on what these parents did at home to support their children's academic achievement. Data were collected using a semi-structured interview protocol and analyzed through the categorical aggregation of transcribed interviews. Key findings revealed that the parents invested time and resources in 3 practices: communicating high expectations, supporting and developing key skills, and communicating with teachers. These findings contribute to social change at both the local and community level by creating a starting point for teachers, principals, and district leaders to reexamine the value of parent input in the educational process, and by providing data to support the revision of current parent involvement policies. Possibilities for further study building upon the findings of this study may focus on student perceptions of their parents' parenting as it relates to their science achievement.

    We tested the incremental validity of an ability measure of emotional intelligence (El) in predicting academic achievement in undergraduate students, controlling for cognitive abilities and personality traits. Academic achievement has been conceptualized in terms of the number of exams, grade point average, and study time taken to prepare for each exam. Additionally, gender differences were taken into account in these relationships. Participants filled in the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT), the Raven's Advanced Progressive Matrices, the reduced version of the Eysenck Personality Questionnaire, and academic achievement measures. Results showed that El abilities were positively related to academic achievement indices, such as the number of exams and grade point average; total El ability and the Perceiving branch were negatively associated with the study time spent preparing for exams. Furthermore, El ability adds a percentage of incremental variance with respect to cognitive ability and personality variables in explaining scholastic success. The magnitude of the associations between El abilities and academic achievement measures was generally higher for men than for women. Jointly considered, the present findings support the incremental validity of the MSCEIT and provide positive indications of the importance of El in students' academic development. The helpfulness of El training in the context of academic institutions is discussed.

  13. Establishing seismic design criteria to achieve an acceptable seismic margin

    1997-01-01

    In order to develop a risk based seismic design criteria the following four issues must be addressed: (1) What target annual probability of seismic induced unacceptable performance is acceptable? (2). What minimum seismic margin is acceptable? (3) Given the decisions made under Issues 1 and 2, at what annual frequency of exceedance should the Safe Shutdown Earthquake ground motion be defined? (4) What seismic design criteria should be established to reasonably achieve the seismic margin defined under Issue 2? The first issue is purely a policy decision and is not addressed in this paper. Each of the other three issues are addressed. Issues 2 and 3 are integrally tied together so that a very large number of possible combinations of responses to these two issues can be used to achieve the target goal defined under Issue 1. Section 2 lays out a combined approach to these two issues and presents three potentially attractive combined resolutions of these two issues which reasonably achieves the target goal. The remainder of the paper discusses an approach which can be used to develop seismic design criteria aimed at achieving the desired seismic margin defined in resolution of Issue 2. Suggestions for revising existing seismic design criteria to more consistently achieve the desired seismic margin are presented.

    Full Text Available Findings presented herein are a part of a large international study of primary school final grade student achievement in mathematics and science (TIMSS 2003. Studies were also conducted on the degree of correlation between student family socioeconomic status, mathematical self-concept and achievement in mathematics. Pilot studies, whose findings are discussed comprised 112 seventh-grade students. "Family socioeconomic status" was defined by variables such as the number of family members, economically disadvantaged/affluent home, and parental educational status. "Mathematical self-concept" was defined as one of the more narrow domains of academic self-concept. "Achievement in mathematics" was measured by the test assessing two dimensions of knowledge of mathematics: content and cognitive skills. The analyses of partial correlations indicate that the most significant predictors of achievement in mathematics test are as follows mathematical self-concept, mother’s educational status and some indicators of family socioeconomic status (access to the Internet, number of household members, number of books available at home. Concerning the correlation found between family characteristics and mathematical self-concept and achievement in mathematics, the developers of current changes in mathematics teaching should not disregard the findings of this study.

    2011-06-24

    Worldwide, a child born in 1955 had an average life expectancy at birth of only 48 years. By 2000, the average life expectancy at birth had increased to 66 years and, if past trends continue, is projected to rise to 73 years by 2025. These improvements in longevity have resulted from improved living conditions overall, advances in medical science, and a number of population-level interventions. However, major disparities persist. During the past decade, in low-income countries, average life expectancy at birth increased from 55 to 57 years (3.6%), while increasing from 78 to 80 years (2.6%) in high-income countries. Analogous to the recent MMWR report highlighting 10 public health achievements that occurred in the United States over the first 10 years of the new century, this report describes global public health achievements during the same period. Experts in global public health were asked to nominate noteworthy public health achievements that occurred outside of the United States during 2001-2010. From them, 10 have been summarized in this report. As with the previous report, the 10 global public health achievements are not ranked in any order. Additional information regarding these achievements is available at http://www.cdc.gov/mmwr/preview/mmwrhtml/mm6019a5_addinfo.htm.

    Full Text Available Research has shown that mathematics achievement in students is influenced by psychological factors such as mathematics anxiety. Weaknesses among students in learning mathematics in particular will affect the efforts of various sectors in making Malaysia a fully developed nation by 2020. The purpose of this study was to determine mathematics anxiety and mathematics achievement among secondary school students in Selangor, Malaysia. The research examined the differences in mathematics anxiety according to gender as well as the differences in mathematics achievement of students based on the level of mathematics anxiety. The study involved195 Form Four students (86 male and 109 female. The instrument used to measure differences was adapted from the Fennema-Sherman Mathematics Attitudes Scale. The data was analyzed using Statistical Package for the Social Sciences (SPSS to determine the mean, frequency, t-test and one-way ANOVA. The findings of the study indicated that there is mathematics anxiety among secondary school students. The t-test showed that the mean difference between mathematics anxiety and gender is not significant. The ANOVA test showed that there were significant differences in achievement based on the level of mathematics anxiety. Thus, math anxiety is one factor that affects student achievement. Therefore, teachers should strive to understand mathematics anxiety and implement teaching and learning strategies so that students can overcome their anxiety.

  17. Expansion coding: Achieving the capacity of an AEN channel

    CERN Document Server

    Koyluoglu, O Ozan; Si, Hongbo; Vishwanath, Sriram

    2012-01-01

    A general method of coding over expansions is proposed, which allows one to reduce the highly non-trivial problem of coding over continuous channels to a much simpler discrete ones. More specifically, the focus is on the additive exponential noise (AEN) channel, for which the (binary) expansion of the (exponential) noise random variable is considered. It is shown that each of the random variables in the expansion corresponds to independent Bernoulli random variables. Thus, each of the expansion levels (of the underlying channel) corresponds to a binary symmetric channel (BSC), and the coding problem is reduced to coding over these parallel channels while satisfying the channel input constraint. This optimization formulation is stated as the achievable rate result, for which a specific choice of input distribution is shown to achieve a rate which is arbitrarily close to the channel capacity in the high SNR regime. Remarkably, the scheme allows for low-complexity capacity-achieving codes for AEN channels, using...

    2012-12-01

    Full Text Available In this paper the relationship among high school students’ mathematics achievement, use of self-regulated learning strategies and cognitive style in the field dependence-independence dimension is examined. Subjects were 128 tenth graders of a public school at Bogotá, Colombia. The MSLQ Questionnaire was used to assess students’ level of self-regulation and the EFT test was used to measure students’ field dependence-independence cognitive style. Mathematics achievement was indicated by the grades obtained by the students during the academic year. Results show that self-regulated learning and cognitive style are related to Math achievement, each one separately. Additionally, complex relations between self-regulation and field dependence-independence were found.

  19. ACHIEVING VALUE FROM ICT IN SMES: KEY MANAGEMENT STRATEGIES

    Directory of Open Access Journals (Sweden)

    K. Johnston

    2009-01-01

    Full Text Available ICT covers a broad range of fields in business and therefore makes ICT value difficult to simply define. The main factors that influence the use of ICT are therefore important to look at, as they give a good understanding of the how much influence the organisation has, on achieving value in its given context. The transformational model of ICT use was analysed to establish how SMEs in South Africa achieve business value from ICT and what management practices are most effective. Implications of the research are that management practices are an important factor that influences the value from ICT, and that the more management practices organisations implement, the greater the business value from ICT. Further findings of this study deduced that organisations that are more ICT aware, gain greater business value from ICT, with value achievement from ICT largely within the organisation’s control. This paper concludes with recommendations for future research.

  20. Entanglement required in achieving entanglement-assisted channel capacities

    CERN Document Server

    Bowen, G

    2002-01-01

    Entanglement shared between the two ends of a quantum communication channel has been shown to be a useful resource in increasing both the quantum and classical capacities for these channels. The entanglement-assisted capacities were derived assuming an unlimited amount of shared entanglement per channel use. In this paper, bounds are derived on the minimum amount of entanglement required per use of a channel, in order to asymptotically achieve the capacity. This is achieved by introducing a class of entanglement-assisted quantum codes. Codes for classes of qubit channels are shown to achieve the quantum entanglement-assisted channel capacity when an amount of shared entanglement per channel given by, E = 1 - Q_E, is provided. It is also shown that for very noisy channels, as the capacities become small, the amount of required entanglement converges for the classical and quantum capacities.

    2015-10-09

    With a randomized field experiment of 587 first-graders, we tested an educational intervention designed to promote interactions between children and parents relating to math. We predicted that increasing math activities at home would increase children's math achievement at school. We tested this prediction by having children engage in math story time with their parents. The intervention, short numerical story problems delivered through an iPad app, significantly increased children's math achievement across the school year compared to a reading (control) group, especially for children whose parents are habitually anxious about math. Brief, high-quality parent-child interactions about math at home help break the intergenerational cycle of low math achievement.

    The present study was undertaken to explore ways projective arid nonprojective verbal measures of achievement motivation elicit comparable and dissimilar responses in a "Third World" sample of entrepreneurs as a test of McClelland's theory of economic growth. Results were generally consistent with the theory of achievement motivation, and suggested that high scores on n Ach were associated with high rates of industrial and agricultural output; low scores were associated with static or declining business. TAT measurement was the best predictor in that it correlated 0.68 and 0.48 with agricultural and industrial production. Results further lend support to past findings: namely, that Various achievement measures appear to be measuring dissimilar constructs.

    Full Text Available ABSTRACT The requirement of television for educational purposes arises when specific educational objectives are not achieved through traditional way of teaching. There are a number of things television can do better than the average teacher and traditional educational institutions, but situations where both teacher and educational institutions are not available, television is the answer to obtain educational objectives, Lochte, (1993. This research paper investigates relationship between TV broadcast time, day and duration and student achievement. Data was collected from 197 from urban and rural, male and female students of the Allama Iqbal Open University, enrolled in the spring 2006 Semester in the selected courses. No strong relationship was found between Learning from TV and academic achievement in the AIOU situation. Use of television in the AIOU Situation will be more effective if transmission day, time and duration are adjusted according to the students’ demand and when students’ assignments are based on both textbook and TV programs.

    Full Text Available Numerous studies have shown that the native language influences foreign word recognition and that this influence is modulated by the proficiency in the nonnative language. Here we explored how the degree of reliance on cross-language similarity (as measured by the cognate facilitation effect together with other domain-general cognitive factors contribute to reading comprehension achievement in a nonnative language at different stages of the learning process. We tested two groups of native speakers of Spanish learning English at elementary and intermediate levels in an academic context. A regression model approach showed that domain-general cognitive skills are good predictors of second language reading achievement independently of the level of proficiency. Critically, we found that individual differences in the degree of reliance on the native language predicted foreign language reading achievement, showing a markedly different pattern between proficiency groups. At lower levels of proficiency the cognate facilitation effect was positively related with reading achievement, while this relation became negative at intermediate levels of foreign language learning. We conclude that the link between native- and foreign-language lexical representations helps participants at initial stages of the learning process, whereas it is no longer the case at intermediate levels of proficiency, when reliance on cross-language similarity is inversely related to successful nonnative reading achievement. Thus, at intermediate levels of proficiency strong and direct mappings from the nonnative lexical forms to semantic concepts are needed to achieve good nonnative reading comprehension, in line with the premises of current models of bilingual lexico-semantic organization.

    Horton, C B; Oakland, T

    1997-01-01

    Considerable interest in applications of temperament theory has led to proposals of four temperament-related learning styles. The hypothesis that achievement is higher when instructional strategies utilize methods consistent with students' preferred learning styles was tested using 417 seventh graders, the majority of whom were from minority and low SES families. The hypothesis was not supported; instead, student achievement was significantly higher with instructional strategies designed to promote personalized learning. The need to extend temperament-based learning styles by considering additional qualities that are important to learning is discussed.

    Full Text Available Cooperative learning refers to instructional methods in which students work in small groups to help each other learn. Four major theoretical perspectives on achievement effects of cooperative learning are reviewed: Motivational, social cohesion, developmental, and cognitive elaboration. Evidence from practical classroom research primarily supports the motivational perspective, which emphasizes the use of group goals and individual accountability for group success. However, there are conditions under which methods derived from all four theoretical perspectives contribute to achievement gain. This chapter reconciles these perspectives in a unified theory of cooperative learning effects.

    Full Text Available Multiple teaching methods are used by teachers in order to improve learning of students. The most popular is lecture method, while very effective is cooperative learning method. Later teaching method had been preferred for teaching science and languages as cited by previous research studies. However, in the subjects of social sciences and humanities, its importance cannot be ignored. Following study is an effort to determine effect of cooperative learning method on students’ achievement in subject of Education.  Qusi experimental design, with pre and post test of control and experimental group was used to achieve target of the study. Sample of the study consisted of 63 female students enrolled in grade 12 of a public college. An achievement test was used as a pre-test, the students were than divided in experimental and control groups. Multiple cooperative learning activities were performed with experimental group by using three common methods of cooperative learning i.e., STAD, TGT and Jigsaw II. The control group was taught by lecture method only. After 8 weeks a post test was administered on both experimental and control group in order to identify difference in achievement. The independent sample t-test was used to measure the mean scores difference between achievement scores of control and treatment groups on pretest.  The results showed that there was no significant difference between the two groups (p=.825 leading to assumption that both groups were on equal level of achievement before intervention.  Same test was applied to find out difference between two groups before and after intervention.  The results showed that there was a significant difference in scores of control and experimental group in post-test. In addition to this paired sample t-test was conducted to compare the effect of intervention on achievement scores of experimental group.  The results showed that there was significant difference between scores of experimental

    Full Text Available A longstanding issue in American education is the gap in academic achievement between majority and minority students. The goal of this study is to accumulate and evaluate evidence on the relationship between state education policies and changes in the Black-White achievement gap, while addressing some of the methodological issues that have led to differences in interpretations of earlier findings. To that end, we consider the experiences of ten states that together enroll more than forty percent of the nation's Black students. We estimate the trajectories of Black student and White student achievement on the NAEP 8th grade mathematics assessment over the period 1992 to 2000, and examine the achievement gap at three levels of aggregation: the state as a whole, groups of schools (strata within a state defined by the SES level of the student population, and within schools within a stratum within a state. From 1992 to 2000, at every level of aggregation, mean achievement rose for both Black students and White students. However, for most states the achievement gaps were large and changed very little at every level of aggregation. The gaps are pervasive, profound and persistent. There is substantial heterogeneity among states in the types of policies they pursued, as well as the coherence and consistency of those policies during the period 1988-1998. We find that states' overall policy rankings (based on our review of the data correlate moderately with their record in improving Black student achievement but are somewhat less useful in predicting their record with respect to reducing the achievement gaps. States' rankings on commitment to teacher quality correlate almost as well as did the overall policy ranking. Thus, state reform efforts are a blunt tool, but a tool nonetheless. Our findings are consistent with the following recommendations: states' reform efforts should be built on broad-based support and buffered as much as possible from changes in

    Full Text Available The objective of the study was to examine the performance characteristics and differences between English and Oriya medium school children on various cognitive processing, reading, academic achievement, and teacher perception measures. The sample consists of 243 schoolchildren, 120 from Grade IV and 123 from Grade VII from three different schools of Cuttack city in Orissa, India. The children were individually administered the Figure-Copying, Raven’s Progressive Matrices, Matching Familiar Figure Task, Serial Recall, Digit-Span, Wechsler’s Intelligence Scale for Children, Block Design, Cloze Reading Comprehension, and Oral Reading tasks. Classroom Achievement scores on different subjects and the teachers’ ratings about their students were also taken. Results revealed that children reading in English medium schools outperformed their Oriya medium counterparts in some cognitive measures such as Figure Copying, MFFT, RPM, and Digit-Span tasks irrespective of levels. However, the children studying in Oriya medium schools scored higher in Reading Comprehension task and commit less error compared with their English medium counterparts. However, in case of academic achievement measures at primary level, the Oriya medium children performed better in social science, whereas the English medium students excelled in first language and mathematics. The teachers of Oriya medium schools also rated their children better in general conduct, motivation, and effort in schoolwork, whereas, at the secondary level, there was no difference between these two groups in academic achievement or teacher perception measures.

    2016-03-01

    Full Text Available The present study examines the achievement goals of university instructors, particularly the structure of such goals, and their relationship to biographic characteristics, other aspects of instructors’ motivation, and teaching quality. Two hundred and fifty-one university instructors (184 without PhD, 97 with PhD, thereof 51 full professors; 146 males, 92 females answered a questionnaire measuring achievement goals, self-efficacy, and enthusiasm in altogether 392 courses. Teaching quality was assessed using reports from 9,241 students who were attending these courses. Confirmatory factor analyses revealed mastery, performance approach, performance avoidance, work avoidance, and relational goals as being distinguishable from each other. Distinct relationships were found between different instructors’ achievement goals, and gender, age, and career status as well as self-efficacy and enthusiasm. Hierarchical linear models suggested positive associations of instructors’ mastery goals with teaching quality, while negative associations were indicated for performance avoidance goals and work avoidance goals in relation to teaching quality. Exploratory analyses conducted due to a quite large correlation between performance approach and performance avoidance goals indicated that for university instructors, differentiating performance goals into appearance and normative components might also be adequate. All in all, the study highlights the auspiciousness of the theoretical concept of university instructors’ achievement goals and contributes to making it comprehensively accessible.

    2012-01-01

    Full Text Available It is hypothesized that students who are categorized in the C-level (low level Achievement Grouping (AG in English instruction classes did not necessarily performed at their peak potential in English language competence. Furthermore, it is assumed that the underlying concepts behind the low achievement levels may lies in two assumptions. First, Brophy (2004 addressed the situation with four categories of students based upon how expectancy-related motivational problems might cause students to develop low expectations for themselves. Second, the concept involving the use of AG, might have cause some of the more capable students to lower their achievement levels in English. In response, an action research was accomplished using a Cooperative Task-Based Learning (CTBL model, based on the concept of learning motivation for students with low achievement levels in an attempt to enhance the students’ English competencies. To evaluate the effectiveness of such teaching methodology, data were collected in the form of interview accounts, self-reflective logs, field notes, observations, and students’ work sheets. Results show that numerous positive outcomes from both the teachers’ and the students’ perspectives were noted from the use of the CTBL. In addition, results also show that cooperative group work has proven to be an effective learning strategy. Lastly, useful implications based on the findings were given to shed light on issues regarding the positive effects of skilled-based curriculum designs.

  19. After exit: Academic achievement patterns of former English language learners.

    Directory of Open Access Journals (Sweden)

    Ester J. de Jong

    2004-09-01

    Full Text Available With few exceptions, accountability systems for programs for English language learners (ELLs have focused on the achievement patterns of ELLs who are still considered “limited English proficient” and program evaluations have been unable to answer the question whether ELLs actually catch up with English proficient peers after attending a bilingual or English as a Second Language (ESL program. Disaggregating data for former ELLs can therefore provide important information for long-term district and program accountability. The study was concerned with the achievement patterns in English language arts, Math, and Science of former ELLs who attended a bilingual and a English as a Second Language (ESL program. It also explored whether length of program participation and grade level exited played a significant role in predicting academic achievement patterns for these exited students. Results indicate that 4th grade students more closely paralleled non- ELL students’ achievement patterns than 8th grade students, particularly for the BE students. While length of program participation is not a significant predictor of former ELLs’ academic success, exit grade does emerge as an important variable to take into consideration in setting exit guidelines.

  12. Academic Effort and Achievement in Science: Beyond a Gendered Relationship

    Science.gov (United States)

    Adamuti-Trache, Maria; Sweet, Robert

    2013-12-01

    This study employs the 2004 School Achievement Indicators Program (SAIP) data to examine whether academic effort manifested by greater investments in school and homework does result in higher literacy scores in science for Canadian students. The study compares four gender-immigrant profiles: Canadian-born males, immigrant males, Canadian-born females, and immigrant females on their scores on teacher-assigned grades in science and on the SAIP science literacy test, and across a range of dispositions, beliefs, and behaviors suggested in the literature as predictive of achievement in science. Study findings show that Canadian-born students, particularly boys, have higher performance in the science literacy test despite their lower achievement in the science classroom and the least investments of time in doing science homework. In contrast, immigrant female students demonstrate the highest academic effort and achievement in science courses which are not matched by similar results in the science literacy test. We discuss these results in relation to different socialization experiences with science and technology that limit female and immigrant students' abilities to transfer knowledge to new situations that have not been learned in the classroom.

    2012-08-01

    Parenting styles have always been a crucial factor in influencing all aspects of a person's development. The purpose of this study is to test the structural equation model of academic achievement among the students using parenting styles as a moderator. The sample comprised 493 students from eight schools. Parenting styles are determined using the Parental Authority Questionnaire (Buri in J Pers Assess 57:110-119, 1991). Academic achievement is measured based on the students' performance in the Lower Secondary Assessment. Data were analyzed using structural equation modelling. Results demonstrated that model of authoritative and model of authoritarian fit the data of this study well. Both authoritative and authoritarian parenting styles are the most common practice of the parents. Parenting styles have been found to be a moderator of this study. The results indicated that parenting styles moderated the effect of academic self-concept on academic achievement. The impact of academic self-concept on academic achievement is found to be greater for the authoritative than the authoritarian parenting style.

    Individuals with tetraplegia lack independent mobility, making them highly dependent on others to move from one place to another. Here, we describe how two macaques were able to use a wireless integrated system to control a robotic platform, over which they were sitting, to achieve independent mobility using the neuronal activity in their motor cortices. The activity of populations of single neurons was recorded using multiple electrode arrays implanted in the arm region of primary motor cortex, and decoded to achieve brain control of the platform. We found that free-running brain control of the platform (which was not equipped with any machine intelligence) was fast and accurate, resembling the performance achieved using joystick control. The decoding algorithms can be trained in the absence of joystick movements, as would be required for use by tetraplegic individuals, demonstrating that the non-human primate model is a good pre-clinical model for developing such a cortically-controlled movement prosthetic. Interestingly, we found that the response properties of some neurons differed greatly depending on the mode of control (joystick or brain control), suggesting different roles for these neurons in encoding movement intention and movement execution. These results demonstrate that independent mobility can be achieved without first training on prescribed motor movements, opening the door for the implementation of this technology in persons with tetraplegia.
