This dissertation addresses the issue of disproportionate female attrition from computer science as an instance of gender segregation in higher education. By adopting a theoretical framework from organizational sociology, it demonstrates that the characteristics and processes of computer science departments strongly influence female retention. The empirical data identifies conditions under which women are retained in the computer science major at comparable rates to men. The research for this dissertation began with interviews of students, faculty, and chairpersons from five computer science departments. These exploratory interviews led to a survey of faculty and chairpersons at computer science and biology departments in Virginia. The data from these surveys are used in comparisons of the computer science and biology disciplines, and for statistical analyses that identify which departmental characteristics promote equal attrition for male and female undergraduates in computer science. This three-pronged methodological approach of interviews, discipline comparisons, and statistical analyses shows that departmental variation in gendered attrition rates can be explained largely by access to opportunity, relative numbers, and other characteristics of the learning environment. Using these concepts, this research identifies nine factors that affect the differential attrition of women from CS departments. These factors are: (1) The gender composition of enrolled students and faculty; (2) Faculty turnover; (3) Institutional support for the department; (4) Preferential attitudes toward female students; (5) Mentoring and supervising by faculty; (6) The local job market, starting salaries, and competitiveness of graduates; (7) Emphasis on teaching; and (8) Joint efforts for student success. This work contributes to our understanding of the gender segregation process in higher education. In addition, it contributes information that can lead to effective solutions for an

Far fewer women than men take computer science classes in high school, enroll in computer science programs in college, or complete advanced degrees in computer science. The computer science pipeline begins to shrink for women even before entering college, but it is at the college level that the "brain drain" is the most evident numerically, especially in the first class taken by most computer science majors called "Computer Science 1" or CS-I. The result, for both academia and industry, is a pronounced technological gender disparity in academic and industrial computer science. The study revealed the existence of several factors influencing success in CS-I. First, and most clearly, the effect of attribution processes seemed to be quite strong. These processes tend to work against success for females and in favor of success for males. Likewise, evidence was discovered which strengthens theories related to prior experience and the perception that computer science has a culture which is hostile to females. Two unanticipated themes related to the motivation and persistence of successful computer science majors. The findings did not support the belief that females have greater logistical problems in computer science than males, or that females tend to have a different programming style than males which adversely affects the females' ability to succeed in CS-I.

The primary objective of this study was to determine the degree to which academic motivation predicted the executive help-seeking, instrumental help-seeking, perceived benefits of help-seeking, and avoidance of help-seeking of high school students enrolled in computer science ( n = 314). Task goals were positively associated with instrumental help-seeking and perceiving the benefits of help-seeking and negatively associated with executive help-seeking; performance-avoid goals were negatively associated with instrumental help-seeking and positively associated with avoiding help-seeking. Controlling for motivation and computer science competence, girls were more likely to seek instrumental help and to perceive the benefits of help-seeking, and African American students were more likely to seek help than were White students or Asian American students. Despite possessing equal computer science skills, girls reported lower self-efficacy, self-concept, self-efficacy for self-regulation, and value than did boys.

Feedback has been identified as a key variable in developing academic self-efficacy. The types of feedback can vary from a traditional, objectivist approach that focuses on minimizing learner errors to a more constructivist approach, focusing on facilitating understanding. The influx of computer-based courses, whether online or through a series of computer-assisted instruction (CAI) modules require that the current research of effective feedback techniques in the classroom be extended to computer environments in order to impact their instructional design. In this study, exposure to different types of feedback during a chemistry CAI module was studied in relation to science self-efficacy (SSE) and performance on an objective-driven assessment (ODA) of the chemistry concepts covered in the unit. The quantitative analysis consisted of two separate ANCOVAs on the dependent variables, using pretest as the covariate and group as the fixed factor. No significant differences were found for either variable between the three groups on adjusted posttest means for the ODA and SSE measures (.95F(2, 106) = 1.311, p = 0.274 and .95F(2, 106) = 1.080, p = 0.344, respectively). However, a mixed methods approach yielded valuable qualitative insights into why only one overall quantitative effect was observed. These findings are discussed in relation to the need to further refine the instruments and methods used in order to more fully explore the possibility that type of feedback might play a role in developing SSE, and consequently, improve academic performance in science. Future research building on this study may reveal significance that could impact instructional design practices for developing online and computer-based instruction.

The Stockpile Stewardship Academic Programs (SSAP) are essential to maintaining a pipeline of professionals to support the technical capabilities that reside at the National Nuclear Security Administration (NNSA) national laboratories, sites, and plants. Since 1992, the United States has observed the moratorium on nuclear testing while significantly decreasing the nuclear arsenal. To accomplish this without nuclear testing, NNSA and its laboratories developed a science-based Stockpile Stewardship Program to maintain and enhance the experimental and computational tools required to ensure the continued safety, security, and reliability of the stockpile. NNSA launched its academic program portfolio more than a decade ago to engage students skilled in specific technical areas of relevance to stockpile stewardship. The success of this program is reflected by the large number of SSAP students choosing to begin their careers at NNSA national laboratories.

Increasingly, new science and technology are expected to solve the nation's current economic malaise. Unfortunately, virtually no industrial laboratories are devoted to anything close to basic research, which, historically, has been the source of many of the innovations on which industry has flourished in the past. For example, a number of industrial laboratories contributed significantly to our basic understanding of polymer science and, in the course of doing so, made better and more useful plastics. The strength of the American system of higher education has always been basic research, which is also the cornerstone of the process of graduate education. Before World War II, academic research was the vehicle by which advanced students learned advanced skills--both cognitive and manipulative. It was the structure devised to produce exemplary scientists who could then apply their skills in a number of different kinds of environments; the research results produced were generally of only secondary interest. Now, the academic research establishment has evolved into the source of the "strategic," "relevant," or "targeted" research that will solve the nation's economic problems. As expectations in this regard grow higher, guidelines are bound to become even more specific. Excessive over-direction of basic research activities can have the effect of throttling down the very industry-building discoveries that are so eagerly sought. From one point of view, targeted academic research often goes in the wrong direction. While it is true that most academic research starts off in some direction, it often does not finish going in that direction. The work that stands behind theses and dissertations often bears little resemblance to the problem that was defined when the student began his/her research. Almost every paper that is written as the result of a piece of academic research is either unsophisticatedin itsdetails or irrelevant, in spite of the initial hopes and promises. That

There are prestigious international awards that recognize the role of theory and experiment in science and mathematics, but there are no awards of a similar stature that explicitly recognize the role of computational science in a scientific field. In 1945, John von Neumann noted that "many branches of both pure and applied mathematics are in great need of computing instruments to break the present stalemate created by the failure of the purely analytical approach to nonlinear problems." In the past few decades, great strides in mathematics and in the applied sciences can be linked to computational science.

Computational Science is an integral component of Brookhaven's multi science mission, and is a reflection of the increased role of computation across all of science. Brookhaven currently has major efforts in data storage and analysis for the Relativistic Heavy Ion Collider (RHIC) and the ATLAS detector at CERN, and in quantum chromodynamics. The Laboratory is host for the QCDOC machines (quantum chromodynamics on a chip), 10 teraflop/s computers which boast 12,288 processors each. There are two here, one for the Riken/BNL Research Center and the other supported by DOE for the US Lattice Gauge Community and other scientific users. A 100 teraflop/s supercomputer will be installed at Brookhaven in the coming year, managed jointly by Brookhaven and Stony Brook, and funded by a grant from New York State. This machine will be used for computational science across Brookhaven's entire research program, and also by researchers at Stony Brook and across New York State. With Stony Brook, Brookhaven has formed the New York Center for Computational Science (NYCCS) as a focal point for interdisciplinary computational science, which is closely linked to Brookhaven's Computational Science Center (CSC). The CSC has established a strong program in computational science, with an emphasis on nanoscale electronic structure and molecular dynamics, accelerator design, computational fluid dynamics, medical imaging, parallel computing and numerical algorithms. We have been an active participant in DOES SciDAC program (Scientific Discovery through Advanced Computing). We are also planning a major expansion in computational biology in keeping with Laboratory initiatives. Additional laboratory initiatives with a dependence on a high level of computation include the development of hydrodynamics models for the interpretation of RHIC data, computational models for the atmospheric transport of aerosols, and models for combustion and for energy utilization. The CSC was formed to bring together

Much has been written in the past two decades about women in academic science careers, but this literature is contradictory. Many analyses have revealed a level playing field, with men and women faring equally, whereas other analyses have suggested numerous areas in which the playing field is not level. The only widely-agreed-upon conclusion is that women are underrepresented in college majors, graduate school programs, and the professoriate in those fields that are the most mathematically intensive, such as geoscience, engineering, economics, mathematics/computer science, and the physical sciences. In other scientific fields (psychology, life science, social science), women are found in much higher percentages. In this monograph, we undertake extensive life-course analyses comparing the trajectories of women and men in math-intensive fields with those of their counterparts in non-math-intensive fields in which women are close to parity with or even exceed the number of men. We begin by examining early-childhood differences in spatial processing and follow this through quantitative performance in middle childhood and adolescence, including high school coursework. We then focus on the transition of the sexes from high school to college major, then to graduate school, and, finally, to careers in academic science. The results of our myriad analyses reveal that early sex differences in spatial and mathematical reasoning need not stem from biological bases, that the gap between average female and male math ability is narrowing (suggesting strong environmental influences), and that sex differences in math ability at the right tail show variation over time and across nationalities, ethnicities, and other factors, indicating that the ratio of males to females at the right tail can and does change. We find that gender differences in attitudes toward and expectations about math careers and ability (controlling for actual ability) are evident by kindergarten and increase
Brown, Paula R.
The protocol of this study was designed to investigate the factors three gifted, young women perceived as influencing their successful transition from an accelerated science high school program to three accelerated university science programs. The research design was a mixed methods study involving three gifted women as they maneuvered through a high school magnet program for science and matriculated into separate university honors programs for science majors. As high school graduates, these women also achieved honors and citations for academic excellence. During their initial years of college, these students maintained outstanding grades in rigorous programs for science majors. These criteria yielded three, gifted female students who proved to be resilient and committed to meeting the demands of an academic program of science. In an attempt to understand the influential factors in the academic lives of these students, a narrative inquiry as well as a quantitative component comprised of three inventories for descriptive data were selected. The impetus for this research resided in the need to better understand the factors contributing to the shaping of the self-identity of the gifted female student as she achieved academic success in the typically, male dominated science classrooms; subsequently, the guidance by parents and educators may prove influential in developing the achievement orientation within the self-identity of the young woman.

Special issue in honour of Jürgen Hafner On 30 September 2010, Jürgen Hafner, one of the most prominent and influential members within the solid state community, retired. His remarkably broad scientific oeuvre has made him one of the founding fathers of modern computational materials science: more than 600 scientific publications, numerous contributions to books, and a highly cited monograph, which has become a standard reference in the theory of metals, witness not only the remarkable productivity of Jürgen Hafner but also his impact in theoretical solid state physics. In an effort to duly acknowledge Jürgen Hafner's lasting impact in this field, a Festsymposium was held on 27-29 September 2010 at the Universität Wien. The organizers of this symposium (and authors of this editorial) are proud to say that a large number of highly renowned scientists in theoretical condensed matter theory—co-workers, friends and students—accepted the invitation to this celebration of Hafner's jubilee. Some of these speakers also followed our invitation to submit their contribution to this Festschrift, published in Journal of Physics: Condensed Matter, a journal which Jürgen Hafner served in 2000-2003 and 2003-2006 as a member of the Advisory Editorial Board and member of the Executive Board, respectively. In the subsequent article, Volker Heine, friend and co-worker of Jürgen Hafner over many decades, gives an account of Hafner's impact in the field of theoretical condensed matter physics.

The study determined how students assess the various components of their science laboratory environment. It also identified how the laboratory environment affects students' learning outcomes. The modified ex-post facto design was used. A sample of 328 randomly selected students was taken from a population of all Senior Secondary School chemistry students in a state in Nigeria. The research instrument, Science Laboratory Environment Inventory (SLEI) designed and validated by Fraser et al. (Sci Educ 77:1-24, 1993) was administered on the selected students. Data analysis was done using descriptive statistics and Product Moment Correlation. Findings revealed that students could assess the five components (Student cohesiveness, Open-endedness, Integration, Rule clarity, and Material Environment) of the laboratory environment. Student cohesiveness has the highest assessment while material environment has the least. The results also showed that the five components of the science laboratory environment are positively correlated with students' academic performance. The findings are discussed with a view to improving the quality of the laboratory environment, subsequent academic performance in science and ultimately the enrolment and retaining of learners in science.

I present some fundamental theorems in computer science and illustrate their relevance in Biology and Physics. I do not assume prerequisites in mathematics or computer science beyond the set N of natural numbers, functions from N to N, the use of some notational conveniences to describe functions, and at some point, a minimal amount of linear algebra and logic. I start with Cantor's transcendental proof by diagonalization of the non enumerability of the collection of functions from natural numbers to the natural numbers. I explain why this proof is not entirely convincing and show how, by restricting the notion of function in terms of discrete well defined processes, we are led to the non algorithmic enumerability of the computable functions, but also-through Church's thesis-to the algorithmic enumerability of partial computable functions. Such a notion of function constitutes, with respect to our purpose, a crucial generalization of that concept. This will make easy to justify deep and astonishing (counter-intuitive) incompleteness results about computers and similar machines. The modified Cantor diagonalization will provide a theory of concrete self-reference and I illustrate it by pointing toward an elementary theory of self-reproduction-in the Amoeba's way-and cellular self-regeneration-in the flatworm Planaria's way. To make it easier, I introduce a very simple and powerful formal system known as the Schoenfinkel-Curry combinators. I will use the combinators to illustrate in a more concrete way the notion introduced above. The combinators, thanks to their low-level fine grained design, will also make it possible to make a rough but hopefully illuminating description of the main lessons gained by the careful observation of nature, and to describe some new relations, which should exist between computer science, the science of life and the science of inert matter, once some philosophical, if not theological, hypotheses are made in the cognitive sciences.

Faculty-to-faculty incivility is especially relevant to academic medical centers because faculty in the health professions must not only meet university tenure and…
Dedicated computers are designed to perform a specific function (such as check-out computers in supermarkets). Because software for these computers is either built in or housed in separate plug-in program modules, programming knowledge is not necessary. The use of these computers to help individuals master basic academic subjects is discussed.…

Ethical behavior in libraries goes beyond service to users. Academic health sciences library directors may need to adhere to the ethical guidelines and rules of their institutions. Does the unique environment of an academic health center imply different ethical considerations? Do the ethical policies of institutions affect these library leaders? Do their personal ethical considerations have an impact as well? In December 2013, a survey regarding the impact of institutional ethics was sent to the director members of the Association of Academic Health Sciences Libraries. The objective was to determine the impact of institutional ethics on these leaders, whether through personal conviction or institutional imperative. PMID:25349542

Israel suffers from a growing problem of socio-economic gaps between those who live in the center of the country and residents of outlying areas. As a result, there is a low level of accessibility to higher education among the peripheral population. The goal of the Sidney Warren Science Education Center for Youth at Tel-Hai College is to strengthen the potential of middle and high school students and encourage them to pursue higher education, with an emphasis on majoring in science and technology. This study investigated the implementation and evaluation of the enrichment science academic program, as an example of informal learning environment, with an emphasis on physics studies. About 500 students conducted feedback survey after participating in science activities in four domains: biology, chemistry, physics, and computer science. Results indicated high level of satisfaction among the students. No differences were found with respect to gender excluding in physics with a positive attitudes advantage among boys. In order to get a deeper understanding of this finding, about 70 additional students conducted special questionnaires, both 1 week before the physics enrichment day and at the end of that day. Questionnaires were intended to assess both their attitudes toward physics and their knowledge and conceptions of the physical concept "pressure." We found that the activity moderately improved boys' attitudes toward physics, but that girls displayed decreased interest in and lower self-efficacy toward physics. Research results were used to the improvement of the instructional design of the physics activity demonstrating internal evaluation process for effective intervention.

In mid-1996, the FDA called for discussions on regulation of clinical software programs as medical devices. In response, a consortium of organizations dedicated to improving health care through information technology has developed recommendations for the responsible regulation and monitoring of clinical software systems by users, vendors, and regulatory agencies. Organizations assisting in development of recommendations, or endorsing the consortium position include the American Medical Informatics Association, the Computer-based Patient Record Institute, the Medical Library Association, the Association of Academic Health Sciences Libraries, the American Health Information Management Association, the American Nurses Association, the Center for Healthcare Information Management, and the American College of Physicians. The consortium proposes four categories of clinical system risks and four classes of measured monitoring and regulatory actions that can be applied strategically based on the level of risk in a given setting. The consortium recommends local oversight of clinical software systems, and adoption by healthcare information system developers of a code of good business practices. Budgetary and other constraints limit the type and number of systems that the FDA can regulate effectively. FDA regulation should exempt most clinical software systems and focus on those systems posing highest clinical risk, with limited opportunities for competent human intervention. PMID:9391932

The Research Institute for Advanced Computer Science (RIACS) carries out basic research and technology development in computer science, in support of the National Aeronautics and Space Administration's missions. RIACS is located at the NASA Ames Research Center. It currently operates under a multiple year grant/cooperative agreement that began on October 1, 1997 and is up for renewal in the year 2002. Ames has been designated NASA's Center of Excellence in Information Technology. In this capacity, Ames is charged with the responsibility to build an Information Technology Research Program that is preeminent within NASA. RIACS serves as a bridge between NASA Ames and the academic community, and RIACS scientists and visitors work in close collaboration with NASA scientists. RIACS has the additional goal of broadening the base of researchers in these areas of importance to the nation's space and aeronautics enterprises. RIACS research focuses on the three cornerstones of information technology research necessary to meet the future challenges of NASA missions: (1) Automated Reasoning for Autonomous Systems. Techniques are being developed enabling spacecraft that will be self-guiding and self-correcting to the extent that they will require little or no human intervention. Such craft will be equipped to independently solve problems as they arise, and fulfill their missions with minimum direction from Earth; (2) Human-Centered Computing. Many NASA missions require synergy between humans and computers, with sophisticated computational aids amplifying human cognitive and perceptual abilities; (3) High Performance Computing and Networking. Advances in the performance of computing and networking continue to have major impact on a variety of NASA endeavors, ranging from modeling and simulation to data analysis of large datasets to collaborative engineering, planning and execution. In addition, RIACS collaborates with NASA scientists to apply information technology research to a

The overall aim of public academic science communication is to engage a non-scientist with a particular field of science and/or research topic, often driven by the expertise of the academic. An e-survey was designed to provide insight into respondent's current and future engagement with science communication activities. Respondents provided a wide range of ideas and concerns as to the 'common practice' of academic science communication, and whilst they support some of these popular approaches (such as open-door events and science festivals), there are alternatives that may enable wider engagement. Suggestions of internet-based approaches and digital media were strongly encouraged, and although respondents found merits in methods such as science festivals, limitations such as geography, time and topic of interest were a barrier to engagement for some. Academics and scientists need to think carefully about how they plan their science communication activities and carry out evaluations, including considering the point of view of the public, as although defaulting to hands-on open door events at their university may seem like the expected standard, it may not be the best way to reach the intended audience.

Analyzing data from the National Education Longitudinal Study of 1988 to 1992, this report examines how computer use produces generic benefit to all children and differential benefits to minority and poor children. Specifically, the authors examined computer use at home vis-a-vis computer use at school in relation to the academic performance of disadvantaged children and their peers (defined by race-ethnicity and socioeconomic status). Home computer use typifies socially differentiated opportunities, whereas school computer use promises generic benefits for all children. The findings suggest that with other relevant conditions constant, (a) disadvantaged children did not lag far behind their peers in computer use at school, but they were much less likely to use computers at home; (b) computer use at home was far more significant than computer use at school in relation to high academic performance; (c) wing a computer at school seemed to have dubious effects on learning—taking computer science courses at school related consistently to low performance far both disadvantaged children and their peers, (d) disadvantaged children benefited less than other children from computer use, including computer use at home; and (e) compared to their peers, disadvantaged children's academic performance seemed less predictable by computer use and other predictor variables.

Educational policies and practices have been largely unsuccessful in closing the achievement gap between Black and White students "Schwartz, 2001". This achievement gap is especially problematic for Black students in science "Maton, Hrabrowski, - Schmitt, 2000. Given the fact that the Black-White achievement gap is still an enigma, the purpose of this article is to address the Black female-Black male academic achievement gap in science majors. Addressing barriers that Black male students may experience as college science and engineering majors, this article presents marketing strategies relative to politics, emotional intelligence, and issues with respect to how science teaching, and Black male students' responses to it, are different. Many Black male students may need to experience a paradigm shift, which structures and enhances their science achievement. Paradigm shifts are necessary because exceptional academic ability and motivation are not enough to get Black males from their first year in a science, technology, education, and mathematics "STEM" major to a bachelor's degree in science and engineering. The conclusions focus on the balance of truth-slippery slopes concerning the confluence of science teachers' further ado and Black male students' theories, methods, and values that position their academic achievement in science and engineering majors.

The purpose of this whitepaper is to provide a framework for understanding the role that verification and validation (V&V) are expected to play in successful ASC Predictive Science Academic Alliance (PSAA) Centers and projects. V&V have been emphasized in the recent specification of the PSAA (NNSA, 2006): (1) The resulting simulation models lend themselves to practical verification and validation methodologies and strategies that should include the integrated use of experimental and/or observational data as a key part of model and sub-model validation, as well as demonstrations of numerical convergence and accuracy for code verification. (2) Verification, validation and prediction methodologies and results must be much more strongly emphasized as research topics and demonstrated via the proposed simulations. (3) It is mandatory that proposals address the following two topics: (a) Predictability in science & engineering; and (b) Verification & validation strategies for large-scale simulations, including quantification of uncertainty and numerical convergence. We especially call attention to the explicit coupling of computational predictability and V&V in the third bullet above. In this whitepaper we emphasize this coupling, and provide concentrated guidance for addressing item 2. The whitepaper has two main components. First, we provide a brief and high-level tutorial on V&V that emphasizes critical elements of the program. Second, we state a set of V&V-related requirements that successful PSAA proposals must address.

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.

Advances in instruction-delivery technology have a direct impact on academic media centers. New technology challenges librarians philosophically, financially, and ethically to provide access to information and instructional systems. Each institution has a unique set of circumstances governing decisions to provide access to hypermedia. If patron needs are met satisfactorily through labs outside the library, it may not be necessary for the library to incorporate hypermedia into its collection. Other library media centers may serve as a main point of access, or a substantial alternative computing resource may exist in departments or professional schools. Regardless of which route is taken, hypermedia is a viable instructional delivery system and can coexist with traditional services. Future studies on various aspects of hypermedia and multimedia management should be encouraged. Academic health sciences librarians would benefit from the study of hypermedia and multimedia collection-development policies, equipment, and personnel management. As computer networking of multimedia and image databases becomes available, it will be interesting to see the role academic health sciences libraries assume in integrating these data-bases with traditional information-delivery systems. Changing technology and instructional methods will affect budgets as well as library relationships with academic departments and computing centers. PMID:8428192

Understanding present barriers to choosing a STEM major is important for science educators so that we may better prepare and inspire future generations of scientists and engineers. This study examined the relationships between participation in competitive science events, gender, race, science self-efficacy, interest in science, and choosing a STEM discipline as a college major. The participants included 1,488 freshman students at a large southeastern public university. Students completed a survey of pre-college experiences with science events, science interests, and college major, as well as, an assessment of science self-efficacy. A subsample of sixty students (30 STEM; 30 non-STEM majors) were interviewed about their participation and academic major choice. Results showed that science, engineering, and non-STEM disciplines were the most frequently reported academic majors. Significant gender differences were found for science self-efficacy and academic major choice. There were significant race differences for participation in specific types of science competitions. Study participants also reported being motivated to participate in a competitive science event as a result of their teacher or parents' encouragement.

Contemporary research into science education has generally been conducted from the perspective of 'conceptual change' in learning. This study sought to extend previous work by recognizing that human rationality can be influenced by the emotions generated by the learning environment and specific actions related to learning. Methods used in educational psychology were adopted to investigate the emotional experience of science students as affected by gender, teaching methods, feedback, and learning tasks. A multidisciplinary research approach combining brain activation measurement with multivariate psychological data theory was employed in the development of a questionnaire intended to reveal the academic emotions of university students in three situations: attending science class, learning scientific subjects, and problem solving. The reliability and validity of the scale was evaluated using exploratory and confirmatory factor analyses. Results revealed differences between the genders in positive-activating and positive-deactivating academic emotions in all three situations; however, these differences manifested primarily during preparation for Science tests. In addition, the emotions experienced by male students were more intense than those of female students. Finally, the negative-deactivating emotions associated with participation in Science tests were more intense than those experienced by simply studying science. This study provides a valuable tool with which to evaluate the emotional response of students to a range of educational situations.

Plastic surgery has passed through a very positive evolution in the last decades on the solid fundament of constantly developing academic plastic surgery. Aim of this paper is an objective evaluation of the current status of academic plastic surgery regarding research topics, currently available ressources and scientific outcome based on a questionnaire. The return rate of the questionnaire in academic departments was 92%. Main topics in research besides wound healing were topics from regenerative medicine such as tissue engineering, biomaterials, genetherapy and angiogenesis with the main focus on skin and fat tissues. In the past five years a total of 25 million Euros of third party research grants were raised. Research relied mainly on interdisciplinary research facilities. Regarding the scientific outcome more than 200 scientific papers were published in basic science research journals having an impactfactor higher than two. These results clearly demonstrate that plastic surgery is scientifically highly productive in academic surroundings where independent departments are established. Considering that independent units of plastic surgery exist in a relatively small number of all 36 university hospitals in germany, it has to be claimed for further independent departments so to provide adequate research facilities for further evolution of academic plastic surgery.

This report details the findings of the DOE ASCR Workshop on Quantum Computing for Science that was organized to assess the viability of quantum computing technologies to meet the computational requirements of the DOE’s science and energy mission, and to identify the potential impact of quantum technologies. The workshop was held on February 17-18, 2015, in Bethesda, MD, to solicit input from members of the quantum computing community. The workshop considered models of quantum computation and programming environments, physical science applications relevant to DOE's science mission as well as quantum simulation, and applied mathematics topics including potential quantum algorithms for linear algebra, graph theory, and machine learning. This report summarizes these perspectives into an outlook on the opportunities for quantum computing to impact problems relevant to the DOE’s mission as well as the additional research required to bring quantum computing to the point where it can have such impact.
In this study, the author developed a model to describe academic self-concept (ASC) in science and validated an instrument for its measurement. Unlike previous models of science ASC, which envisage science as a homogenous single global construct, this model took a multidimensional view by conceiving science self-concept as possessing distinctive facets including conceptual and procedural elements. In the first part of the study, data were collected from 1,483 students attending eight secondary schools in England, through the use of a newly devised Secondary Self-Concept Science Instrument, and structural equation modeling was employed to test and validate a model. In the second part of the study, the data were analysed within the new self-concept framework to examine learners' ASC profiles across the domains of science, with particular attention paid to age- and gender-related differences. The study found that the proposed science self-concept model exhibited robust measures of fit and construct validity, which were shown to be invariant across gender and age subgroups. The self-concept profiles were heterogeneous in nature with the component relating to self-concept in physics, being surprisingly positive in comparison to other aspects of science. This outcome is in stark contrast to data reported elsewhere and raises important issues about the nature of young learners' self-conceptions about science. The paper concludes with an analysis of the potential utility of the self-concept measurement instrument as a pedagogical device for science educators and learners of science.

Reversing is the notion of thinking or working in reverse. Computer science textbooks and tutors recognize it primarily in the form of recursion. However, recursion is only one form of reversing. Reversing appears in the computer science curriculum in many other forms, at various intellectual levels, in a variety of fundamental courses. As such,…

The significance of computer science for economics and society is undisputed. In particular, computer science is acknowledged to play a key role in schools (e.g., by opening multiple career paths). The provision of effective computer science education in schools is dependent on teachers who are able to properly represent the discipline and whose…
Scientists usually identify themselves as either theoreticians or experimentalists, while technology - the application of science in practice - is done by engineers. In computer science, these distinctions are often blurred. This paper examines the history of major achievements in computer science as portrayed by the winners of the prestigious Turing Award and identifies a possibly unique activity called Theory-Guided Technology (TGT). Researchers develop TGT by using theoretical results to create practical technology. The reasons why TGT is practical in computer science are discussed, as is the cool reception that TGT has been received by software engineers.

COAChing (Committee on the Advancement of Women Chemists) was formed in 1998 by a group of senior women chemists to address issues related to the documented disparity in hiring, promotion, and advancement of women faculty in academic chemistry departments in the United States. Several national programs have been launched by COACh that are already showing a high degree of impact on the lives and careers of many women chemists in the academic arena. As word of the effectiveness of these programs has spread, other science disciplines (including physics, biology, mathematics, and computer science) have adopted COACh programs with similar goals in mind. This article describes several opportunities that COACh is providing to help increase the number and success of women scientists in academia.

Over the last three decades, the biological research has undergone drastic change. In addition to the many scientific and technological advancements, the legal, and hence economic, structures within which biological research occurs have also been significantly altered. In the early 1980's the patent laws were extended to encompass almost all products of biological research, including living organisms, and the U.S. Congress passed a series of laws which encouraged the intertwining of academic and industrial interests. This research explores how these legal and economic changes have shaped academic research agendas in the biological sciences. Using the University of California, Berkeley as a case study, I have employed a variety of quantitative and qualitative methods to (a) map the directions of biological research occurring in the four main UC Berkeley biology departments over the last two and a half decades, (b) characterize industrial involvement in biological research at UC Berkeley, and (c) understand the decision making calculus scientists and university administrators employ in crafting their personal research agendas and the research directions for their departments and colleges. This dissertation elucidates the necessary convergence of interests, resources, and skills required for any research project to proceed, explores the motivation of academic strength in both the laboratory and the university as a whole, and finally examines the co-construction of the cutting edge These concepts offer new insight into understanding the processes through which science takes its shape.

Academic pharmaceutical science research is expanding further and further from the University setting to encompass the for-profit private company setting. This parallels the National Institutes of Health momentum to include multiple funding opportunities for University and private company collaboration. It has been recognized that the nonprofit and for-profit combination research model can accelerate the commercialization of pharmaceutical products, and therefore more efficiently improve human health. Entrepreneurial activities require unique considerations in the University environment, but can be modeled after the commercialization expansion of the academic healthcare enterprise. Challenges and barriers exist to starting a company as an entrepreneurial faculty member, but the rewards to one's personal and professional lives are incomparable. PMID:20017206

Scholars and pundits alike argue that U.S. scientists could do more to reach out to the general public. Yet, to date, there have been few systematic studies that examine how scientists understand the barriers that impede such outreach. Through analysis of 97 semi-structured interviews with academic biologists and physicists at top research universities in the United States, we classify the type and target audiences of scientists’ outreach activities. Finally, we explore the narratives academic scientists have about outreach and its reception in the academy, in particular what they perceive as impediments to these activities. We find that scientists’ outreach activities are stratified by gender and that university and disciplinary rewards as well as scientists’ perceptions of their own skills have an impact on science outreach. Research contributions and recommendations for university policy follow. PMID:22590526

Cloud Computing holds tremendous potential for missions across the National Aeronautics and Space Administration. Several flight missions are already benefiting from an investment in cloud computing for mission critical pipelines and services through faster processing time, higher availability, and drastically lower costs available on cloud systems. However, these processes do not currently extend to general scientific algorithms relevant to earth science missions. The members of the Airborne Cloud Computing Environment task at the Jet Propulsion Laboratory have worked closely with the Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) mission to integrate cloud computing into their science data processing pipeline. This paper details the efforts involved in deploying a science data system for the CARVE mission, evaluating and integrating cloud computing solutions with the system and porting their science algorithms for execution in a cloud environment.

Quantitative social science is not only about regression analysis or, in general, data inference. Computer simulations of social mechanisms have an over 60 years long history. They have been used for many different purposes—to test scenarios, to test the consistency of descriptive theories (proof-of-concept models), to explore emergent phenomena, for forecasting, etc. In this essay, we sketch these historical developments, the role of mechanistic models in the social sciences and the influences from the natural and formal sciences. We argue that mechanistic computational models form a natural common ground for social and natural sciences, and look forward to possible future information flow across the social-natural divide.

BACKGROUND: Burnout experienced by physicians is concerning because it may affect quality of care. OBJECTIVE: To determine the frequency of burnout among physicians at an academic health science centre and to test the hypothesis that work hours are related to burnout. METHODS: All 300 staff physicians, contacted through their personal e-mail, were provided an encrypted link to an anonymous questionnaire. The primary outcome measure, the Copenhagen Burnout Inventory, has three subscales: personal, work related and patient related. RESULTS: The response rate for the questionnaire was 70%. Quantitative demands, insecurity at work and job satisfaction affected all three components of burnout. Of 210 staff physicians, 22% (n=46) had scores indicating personal burnout, 14% (n=30) had scores indicating work-related burnout and 8% (n=16) had scores indicating patient-related burnout. The correlation between total hours worked and total burnout was only 0.10 (P=0.14) DISCUSSION: Up to 22% of academic paediatric physicians had scores consistent with mild to severe burnout. A simple reduction in work hours is unlikely to be successful in reducing burnout and, therefore, quantitative demands, job satisfaction and work insecurity may require attention to address burnout among academic physicians.

The present study was designed to examine the relationship between the criterion variables of science-related attitudes and the predictor variables of gender, self-concept, ethnic origin, mother's occupation, father's occupation, socioeconomic status, and achievement in academically talented students. One hundred and sixty-seven students in grades 11 and 12 from a residential math and science high school in Alabama were administered the Test of Science-Related Attitudes (TOSRA; Fraser, 1981), the Piers-Harris Children's Self-Concept Scale (Piers & Harris, 1969), and a general information questionnaire. Multiple linear regression consisting of canonical correlation, semi-partial correlation, and Manova were used to test the hypotheses of this study. Results indicate that students had favorable attitudes towards science. Significant interactions were found between gender and achievement for the Adoption of Scientific Attitude subtest with high achieving females having more favorable attitudes on this variable followed by low achieving males. Additionally, significant interactions were found between self-concept and achievement and between mother's occupation and father's occupation on the Attitude Toward Normality of Scientists subtest. High achievers with high self-concept obtained the highest scores while low achievers with low self-concept obtained the lowest scores on the Attitude Toward Normality of Scientist subtest. Subjects with fathers and mothers in science occupations obtained the highest scores on the Attitude Toward Normality of Scientist subtest while subjects with a father in a nonscience occupation and a mother in a science occupation obtained the lowest scores. The lowest scores were found in Leisure Interest in Science regardless of gender, self-concept, ethnic origin, mother's occupation, father's occupation, socioeconomic status, or achievement.

The term ICT4D refers to the opportunities of Information and Communication Technology (ICT) as an agent of development. Research in that field is often focused on evaluating the feasibility of existing technologies, mostly of Western or Far East Asian origin, in the context of developing regions. A computer science perspective is complementary to that agenda. The computer science perspective focuses on exploring the resources, or inputs, of a particular context and on basing the design of a technical intervention on the available resources, so that the output makes a difference in the development context. The modus operandi of computer science, construction, interacts with evaluation and exploration practices. An analysis of a contextualized information technology curriculum of Tumaini University in southern Tanzania shows the potential of the computer science perspective for designing meaningful information and communication technology for a developing region.

The purpose of this life story narrative study was to explore how women scientists develop views of self that enable them to negotiate careers within academic science. I framed the study using feminist standpoint theory as my theoretical foundation, and used possible selves theory as my conceptual framework. Eight women scientists working in academe described their journey regarding their views of self and career-related experiences. The study produced two key findings. First, seven themes emerged from my data analysis; these themes suggest that these women shared significant experiences in their quest to become scientists. Second, my feminist analysis of the participants' narratives indicates that distinct, but submerged gender-related tensions shaped their views of themselves as scientists and their science career decisions. These tensions include career choice and advancement constrained by family obligations, work environments that do not recognize or undervalue their skills and contributions to the profession, and perceived pressure to de-feminize their behavior to blend in to their work environment. Not unlike other women negotiating careers in academic science, they generally accepted their status as women to be an inherent part of their career pursuits and viewed workplace challenges as an opportunity to prove their competency. Seven of the eight women did not attribute their challenges to gender differences. However, the combined narratives revealed underlying conflicts between their views of self as women and as scientists resulting from their experiences in, and perceptions of, academic science environments. The study's principal theoretical contribution, from the feminist standpoint perspective, highlights the pervasive and unseen influence of gender dynamics. In this study, the participants developed views of themselves, not as scientists, but as "educators who work in science." This critical distinction enabled these participants, perhaps unknowingly

Two surveys of college students were conducted to study the students' perceptions and knowledge of computer science as a profession and as a career. Ignorance of the field was consistently observed in both samples. Students with an aptitude for computing tend to blame their high schools, media, and society for their lack of knowledge. These findings suggest that high school students need to be provided with a more balanced perspective on computing.

This survey is devoted to the development of informatics and computer science in Armenia. The results in theoretical computer science (algebraic models, solutions to systems of general form recursive equations, the methods of coding theory, pattern recognition and image processing), constitute the theoretical basis for developing problem-solving-oriented environments. As examples can be mentioned: a synthesizer of optimized distributed recursive programs, software tools for cluster-oriented implementations of two-dimensional cellular automata, a grid-aware web interface with advanced service trading for linear algebra calculations. In the direction of solving scientific problems that require high-performance computing resources, examples of completed projects include the field of physics (parallel computing of complex quantum systems), astrophysics (Armenian virtual laboratory), biology (molecular dynamics study of human red blood cell membrane), meteorology (implementing and evaluating the Weather Research and Forecast Model for the territory of Armenia). The overview also notes that the Institute for Informatics and Automation Problems of the National Academy of Sciences of Armenia has established a scientific and educational infrastructure, uniting computing clusters of scientific and educational institutions of the country and provides the scientific community with access to local and international computational resources, that is a strong support for computational science in Armenia.
The Second SIAM Conference on Computational Science and Engineering was held in San Diego from February 10-12, 2003. Total conference attendance was 553. This is a 23% increase in attendance over the first conference. The focus of this conference was to draw attention to the tremendous range of major computational efforts on large problems in science and engineering, to promote the interdisciplinary culture required to meet these large-scale challenges, and to encourage the training of the next generation of computational scientists. Computational Science & Engineering (CS&E) is now widely accepted, along with theory and experiment, as a crucial third mode of scientific investigation and engineering design. Aerospace, automotive, biological, chemical, semiconductor, and other industrial sectors now rely on simulation for technical decision support. For federal agencies also, CS&E has become an essential support for decisions on resources, transportation, and defense. CS&E is, by nature, interdisciplinary. It grows out of physical applications and it depends on computer architecture, but at its heart are powerful numerical algorithms and sophisticated computer science techniques. From an applied mathematics perspective, much of CS&E has involved analysis, but the future surely includes optimization and design, especially in the presence of uncertainty. Another mathematical frontier is the assimilation of very large data sets through such techniques as adaptive multi-resolution, automated feature search, and low-dimensional parameterization. The themes of the 2003 conference included, but were not limited to: Advanced Discretization Methods; Computational Biology and Bioinformatics; Computational Chemistry and Chemical Engineering; Computational Earth and Atmospheric Sciences; Computational Electromagnetics; Computational Fluid Dynamics; Computational Medicine and Bioengineering; Computational Physics and Astrophysics; Computational Solid Mechanics and Materials; CS

As hospitals incorporate information technology (IT), their operations become increasingly vulnerable to technological breakdowns and attacks. Proper emergency management and business continuity planning require an approach to identify, mitigate, and work through IT downtime. Hospitals can prepare for these disasters by reviewing case studies. This case study details the disruption of computer operations at Mount Sinai Medical Center (MSMC), an urban academic teaching hospital. The events, and MSMC's response, are narrated and the impact on hospital operations is analyzed. MSMC's disaster management strategy prevented computer failure from compromising patient care, although walkouts and time-to-disposition in the emergency department (ED) notably increased. This incident highlights the importance of disaster preparedness and mitigation. It also demonstrates the value of using operational data to evaluate hospital responses to disasters. Quantifying normal hospital functions, just as with a patient's vital signs, may help quantitatively evaluate and improve disaster management and business continuity planning. PMID:24352930

With launching of Sputnik by the Soviet Union in the late 1950s, science and technology became a high priority in the United States. During the two decades since, health sciences libraries have experienced changes in almost all aspects of their operations. Additionally, recent developments in medical care and in medical education have had major influences on the mission of health science libraries. In the unending struggle to keep up with new technologies and services, libraries have had to support increasing demands while they receive a decreasing share of the health care dollar. This paper explores the economic challenges faced by academic health sciences libraries and suggests measures for augmenting traditional sources of funding. The development of marketing efforts, institutional memberships, and fee-based services by the Louis Calder Memorial Library, University of Miami School of Medicine, is presented as a case study.

In this chapter, we review basic concepts from probability theory and computational statistics that are fundamental to evolutionary genomics. We provide a very basic introduction to statistical modeling and discuss general principles, including maximum likelihood and Bayesian inference. Markov chains, hidden Markov models, and Bayesian network models are introduced in more detail as they occur frequently and in many variations in genomics applications. In particular, we discuss efficient inference algorithms and methods for learning these models from partially observed data. Several simple examples are given throughout the text, some of which point to models that are discussed in more detail in subsequent chapters. PMID:22407706
Plagiarism of computer programs has long been a problem in higher education. Ease of electronic copying, vague understanding by students as to what constitutes plagiarism, increasing acceptance of plagiarism by students, lack of enforcement by instructors and school administrators, and a whole host of other factors contribute to plagiarism. The first step in curbing plagiarism is prevention, the second (and much less preferable) is detection. History files and software metrics can be used as a tool to aid in detecting possible plagiarism. This paper gives advice concerning how to deal with plagiarism and with using software monitors to detect plagiarism.

Life in a technological society brings new paradigms and pressures to bear on education. These pressures are magnified for underrepresented students and must be addressed if they are to play a vital part in society. Educational pipelines need to be established to provide at risk students with the means and opportunity to succeed in science, technology, engineering, and mathematics (STEM) majors. STEM educational pipelines are programs consisting of components that seek to facilitate students' completion of a college degree by providing access to higher education, intervention, mentoring, support infrastructure, and programs that encourage academic success. Successes in the STEM professions mean that more educators, scientist, engineers, and researchers will be available to add diversity to the professions and to provide role models for future generations. The issues that the educational pipelines must address are improving at risk groups' perceptions and awareness of the math, science, and engineering professions. Additionally, the educational pipelines must provide intervention in math preparation, overcome gender and race socialization, and provide mentors and counseling to help students achieve better self perceptions and provide positive role models. This study was designed to explorer the underrepresentation of minorities and women in the computer science major at Rowan University through a multilayered action research methodology. The purpose of this research study was to define and understand the needs of underrepresented students in computer science, to examine current policies and enrollment data for Rowan University, to develop a historical profile of the Computer Science program from the standpoint of ethnicity and gender enrollment to ascertain trends in students' choice of computer science as a major, and an attempt to determine if raising awareness about computer science for incoming freshmen, and providing an alternate route into the computer science

In this age of data-driven science and high-throughput biology, computational thinking is becoming an increasingly important skill for tackling both new and long-standing biological questions. However, despite its obvious importance and conspicuous integration into many areas of biology, computer science is still viewed as an obscure field that has, thus far, permeated into only a few of the biology curricula across the nation. A national survey has shown that lack of computational literacy in environmental sciences is the norm rather than the exception [Valle & Berdanier (2012) Bulletin of the Ecological Society of America, 93, 373-389]. In this article, we seek to introduce a few important concepts in computer science with the aim of providing a context-specific introduction aimed at research biologists. Our goal was to help biologists understand some of the most important mainstream computational concepts to better appreciate bioinformatics methods and trade-offs that are not obvious to the uninitiated.

Technology has improved many educational issues. This is a very exciting time for technology and education. The primary purpose of this study was aimed at understanding the impact of home computer use on academic achievement in the computer curriculum of the 12th grade students in Riyadh, Kingdom of Saudi Arabia. In particular, the study attempted to determine if the use of home computers would be an effective manner for increasing students' academic achievement. The participants of the study were 240 male and female students as a random sample from 12th grade from eight random high schools in Riyadh, Saudi Arabia. An achievement exam and survey were developed by the researcher based on the computer science curriculum topics, the quantitative data was collected in both a single achievement exam and a single survey from a sample of 240 Saudi high school students. Both the survey and an achievement exam were split equally between male and female students. The study sought the answer to 10 questions. Analysis of variance (ANOVA), followed by tests of simple main effects and post hoc comparisons using Scheffe, as well as Pearson Correlation were conducted to answer the research questions. The study results pointed out that home computers were important to support the students in their academic achievement in the computer science curriculum. Therefore, more attention must be given to the use of home computers for all students. Moreover, we should attempt to treat the difficulties which students face for getting computers in their homes.

The boundaries of computer science are defined by what symbolic computation can accomplish. Software Engineering is concerned with effective use of computing technology to support automatic computation on a large scale so as to construct desirable solutions to worthwhile problems. Both focus on what happens within the machine. In contrast, most practical applications of computing support end-users in realizing (often unsaid) objectives. It is often said that such objectives cannot be even specified, e.g., what is the specification of MS Word, or for that matter, any flavour of UNIX? This situation points to the need for architecting what people do with computers. Based on Systems Thinking and Cybernetics, we present such a viewpoint which hinges on Human Responsibility and means of living up to it.

Scientific computation has come into its own as a mature technology in all fields of science. Never before have we been able to accurately anticipate, analyze, and plan for complex events that have not yet occurred from the operation of a reactor running at 100 million degrees centigrade to the changing climate a century down the road. Combined with the more traditional approaches of theory and experiment, scientific computation provides a profound tool for insight and solution as we look at complex systems containing billions of components. Nevertheless, it cannot yet do all we would like. Much of scientific computation s potential remains untapped in areas such as materials science, Earth science, energy assurance, fundamental science, biology and medicine, engineering design, and national security because the scientific challenges are far too enormous and complex for the computational resources at hand. Many of these challenges are of immediate global importance. These challenges can be overcome by a revolution in computing that promises real advancement at a greatly accelerated pace. Planned petascale systems (capable of a petaflop, or 1015 floating point operations per second) in the next 3 years and exascale systems (capable of an exaflop, or 1018 floating point operations per second) in the next decade will provide an unprecedented opportunity to attack these global challenges through modeling and simulation. Exascale computers, with a processing capability similar to that of the human brain, will enable the unraveling of longstanding scientific mysteries and present new opportunities. Table ES.1 summarizes these scientific opportunities, their key application areas, and the goals and associated benefits that would result from solutions afforded by exascale computing.

How to integrate simulation-based engineering and science (SBES) into the science curriculum smoothly is a challenging question. For the importance of SBES to be appreciated, the core value of simulations-that they help people understand natural phenomena and solve engineering problems-must be taught. A strategy to achieve this goal is to introduce computational experiments to the science curriculum to replace or supplement textbook illustrations and exercises and to complement or frame hands-on or wet lab experiments. In this way, students will have an opportunity to learn about SBES without compromising other learning goals required by the standards and teachers will welcome these tools as they strengthen what they are already teaching. This paper demonstrates this idea using a number of examples in physics, chemistry, and engineering. These exemplary computational experiments show that it is possible to create a curriculum that is both deeper and wider.

Video-gaming is a common pastime among adolescents, particularly adolescent males in industrialized nations. Despite widespread suggestions that video-gaming negatively affects academic achievement, the evidence is inconclusive. We reanalyzed data from over 192,000 students in 22 countries involved in the 2009 Programme for International Student Assessment (PISA) to estimate the true effect size of frequency of videogame use on adolescent academic achievement in science, mathematics and reading. Contrary to claims that increased video-gaming can impair academic performance, differences in academic performance were negligible across the relative frequencies of videogame use. Videogame use had little impact on adolescent academic achievement. PMID:24699536

We join the increasing call to take computational education of life science students a step further, beyond teaching mere programming and employing existing software tools. We describe a new course, focusing on enriching the curriculum of life science students with abstract, algorithmic, and logical thinking, and exposing them to the computational "culture." The design, structure, and content of our course are influenced by recent efforts in this area, collaborations with life scientists, and our own instructional experience. Specifically, we suggest that an effective course of this nature should: (1) devote time to explicitly reflect upon computational thinking processes, resisting the temptation to drift to purely practical instruction, (2) focus on discrete notions, rather than on continuous ones, and (3) have basic programming as a prerequisite, so students need not be preoccupied with elementary programming issues. We strongly recommend that the mere use of existing bioinformatics tools and packages should not replace hands-on programming. Yet, we suggest that programming will mostly serve as a means to practice computational thinking processes. This paper deals with the challenges and considerations of such computational education for life science students. It also describes a concrete implementation of the course and encourages its use by others. PMID:25411839

The purpose and scope of this dissertation is to investigate the origins and development of academic computer science units in American higher education and examine the intent and structure of their curricula. Specifically the study examines selected undergraduate and graduate curricula that developed from 1950 to 1975. This dissertation examines several of the earliest academic units formed and the issues surrounding their formation. This study examines some of the variety of courses and programs that existed among the early computer science programs. The actual titles of the units varied but they shared a common overreaching goal to study computers. The departments formed in various methods and some units were a subset of other departments. Faculties of these new units were often comprised of faculty members from various other disciplines. This dissertation is an exploration of the connections between a variety of diverse institutions and the new computer science discipline that formed from these early academic roots. While much has been written about the history of hardware and software development and the individual pioneers in the relatively new computer science discipline, the history of the academic units was documented primarily based on individual institutions. This study uses a wider lens to examine the patterns of these early academic units as they formed and became computer science units. The successes of these early pioneers resulted in a proliferation of academic computer programs in the following decades. The curricular debates continue as the number and purposes of these programs continue to expand. This dissertation seeks to provide useful information for future curricular decisions by examining the roots of the academic computer science units.

It has long been recognized that numerical modelling and computer simulations can be used as a powerful research tool to understand, and sometimes to predict, the tendencies and peculiarities in the dynamics of populations and ecosystems. It has been, however, much less appreciated that the context of modelling and simulations in ecology is essentially different from those that normally exist in other natural sciences. In our paper, we review the computational challenges arising in modern ecology in the spirit of computational mathematics, i.e. with our main focus on the choice and use of adequate numerical methods. Somewhat paradoxically, the complexity of ecological problems does not always require the use of complex computational methods. This paradox, however, can be easily resolved if we recall that application of sophisticated computational methods usually requires clear and unambiguous mathematical problem statement as well as clearly defined benchmark information for model validation. At the same time, many ecological problems still do not have mathematically accurate and unambiguous description, and available field data are often very noisy, and hence it can be hard to understand how the results of computations should be interpreted from the ecological viewpoint. In this scientific context, computational ecology has to deal with a new paradigm: conventional issues of numerical modelling such as convergence and stability become less important than the qualitative analysis that can be provided with the help of computational techniques. We discuss this paradigm by considering computational challenges arising in several specific ecological applications. PMID:23565336

In this paper we describe software for science instruction that is based upon a constructivist epistemology of learning. From a constructivist perspective, the process of learning is viewed as an active construction of knowledge, rather than a passive reception of information. The computer has the potential to provide an environment in which students can explore their understanding and better construct scientific knowledge. The Explorer is an interactive environment that integrates animated computer models with analytic capabilities for learning and teaching science. The system include graphs, a spreadsheet, scripting, and interactive tools. During formative evaluation of Explorer in the classroom, we have focused on learning the function and effectiveness of computer models in teaching science. Models have helped students relate theory to experiment when used in conjunction with hands-on activities and when the simulation addressed students' naive understanding of the phenomena. Two classroom examples illustrate our findings. The first is based on the dynamics of colliding objects. The second describes a class modeling the function of simple electric circuits. The simulations bridge between phenomena and theory by providing an abstract representation on which students may make measurements. Simulations based on scientific theory help to provide a set of interrelated experiences that challenge students' informal understanding of the science.

Scientific visualization is developing rapidly, stimulated by computational science, which is gaining acceptance as a third alternative to theory and experiment. Computational science is based on numerical simulations of mathematical models derived from theory. But each individual simulation is like a hypothetical experiment; initial conditions are specified, and the result is a record of the observed conditions. Experiments can be simulated for situations that can not really be created or controlled. Results impossible to measure can be computed.. Even for observable values, computed samples are typically much denser. Numerical simulations also extend scientific exploration where the mathematics is analytically intractable. Numerical simulations are used to study phenomena from subatomic to intergalactic scales and from abstract mathematical structures to pragmatic engineering of everyday objects. But computational science methods would be almost useless without visualization. The obvious reason is that the huge amounts of data produced require the high bandwidth of the human visual system, and interactivity adds to the power. Visualization systems also provide a single context for all the activities involved from debugging the simulations, to exploring the data, to communicating the results. Most of the presentations today have their roots in image processing, where the fundamental task is: Given an image, extract information about the scene. Visualization has developed from computer graphics, and the inverse task: Given a scene description, make an image. Visualization extends the graphics paradigm by expanding the possible input. The goal is still to produce images; the difficulty is that the input is not a scene description displayable by standard graphics methods. Visualization techniques must either transform the data into a scene description or extend graphics techniques to display this odd input. Computational science is a fertile field for visualization

The purpose of this study was to determine if spatial intelligence contributes to a student's success in a computer science major or if mathematical-logical intelligence is sufficient data on which to base a prediction of success. The study was performed at a small university. The sample consisted of 15 computer science (CS) majors, enrolled in a computer science class, and 15 non-CS-majors, enrolled in a statistics class. Seven of the CS-majors were considered advanced and seven were considered less advanced. The independent measures were: the mathematics and the English scores from the ACT/SAT (CS-majors); a questionnaire to obtain personal information; the major area of study which compared CS-majors to all other majors; and the number of completed computer science classes (CS-majors) to determine advanced and less advanced CS-majors. The dependent measures were: a multiple intelligence inventory for adults to determine perception of intelligences; the GEFT to determine field independence independence; the Card Rotations Test to determine spatial orientation ability; the Maze Tracing Speed Test to determine spatial scanning ability; and the Surface Development test to determine visualization ability. The visualization measure correlated positively and significantly with the GEFT. The year in college correlated positively and significantly with the GEFT and visualization measure for CS-majors and correlated negatively for non-CS-majors. Although non-CS-majors scored higher on the spatial orientation measure, CS-majors scored significantly higher on the spatial scanning measure. The year in college correlated negatively with many of the measures and perceptions of intelligences among both groups; however, there were more significant negative correlations among non-CS-majors. Results indicated that experience in computer programming may increase field independence, visualization ability, and spatial scanning ability while decreasing spatial orientation ability. The

Computational thinking aims to outline fundamental skills from computer science that everyone should learn. As currently defined, with help from the National Science Foundation (NSF), these skills include problem formulation, logically organizing data, automating solutions through algorithmic thinking, and representing data through abstraction. One aim of the NSF is to integrate these and other computational thinking concepts into the classroom. End-user programming tools offer a unique opportunity to accomplish this goal. An end-user programming tool that allows students with little or no prior experience the ability to create simulations based on phenomena they see in-class could be a first step towards meeting most, if not all, of the above computational thinking goals. This thesis describes the creation, implementation and initial testing of a programming tool, called the Simulation Creation Toolkit, with which users apply high-level agent interactions called Computational Thinking Patterns (CTPs) to create simulations. Employing Computational Thinking Patterns obviates lower behavior-level programming and allows users to directly create agent interactions in a simulation by making an analogy with real world phenomena they are trying to represent. Data collected from 21 sixth grade students with no prior programming experience and 45 seventh grade students with minimal programming experience indicates that this is an effective first step towards enabling students to create simulations in the classroom environment. Furthermore, an analogical reasoning study that looked at how users might apply patterns to create simulations from high- level descriptions with little guidance shows promising results. These initial results indicate that the high level strategy employed by the Simulation Creation Toolkit is a promising strategy towards incorporating Computational Thinking concepts in the classroom environment.

California community colleges contribute alarmingly few computer science degree or certificate earners. While the literature shows clear K-12 impediments to CS matriculation in higher education, very little is known about the experiences of those who overcome initial impediments to CS yet do not persist through to program completion. This phenomenological study explores insights into that specific experience by interviewing underrepresented, low income, first-generation college students who began community college intending to transfer to 4-year institutions majoring in CS but switched to another field and remain enrolled or graduated. This study explores the lived experiences of students facing barriers, their avenues for developing interest in CS, and the persistence support systems they encountered, specifically looking at how students constructed their academic choice from these experiences. The growing diversity within California's population necessitates that experiences specific to underrepresented students be considered as part of this exploration. Ten semi-structured interviews and observations were conducted, transcribed and coded. Artifacts supporting student experiences were also collected. Data was analyzed through a social-constructivist lens to provide insight into experiences and how they can be navigated to create actionable strategies for community college computer science departments wishing to increase student success. Three major themes emerged from this research: (1) students shared pre-college characteristics; (2) faced similar challenges in college CS courses; and (3) shared similar reactions to the "work" of computer science. Results of the study included (1) CS interest development hinged on computer ownership in the home; (2) participants shared characteristics that were ideal for college success but not CS success; and (3) encounters in CS departments produced unique challenges for participants. Though CS interest was and remains

Within the last two decades, Modeling and Simulation (M&S) has become the tool of choice to investigate the behavior of complex phenomena. Successes encountered in 'hard' sciences are prompting interest to apply a similar approach to Computational Social Sciences in support, for example, of national security applications faced by the Intelligence Community (IC). This manuscript attempts to contribute to the debate on the relevance of M&S to IC problems by offering an overview of what it takes to reach 'predictability' in computational sciences. Even though models developed in 'soft' and 'hard' sciences are different, useful analogies can be drawn. The starting point is to view numerical simulations as 'filters' capable to represent information only within specific length, time or energy bandwidths. This simplified view leads to the discussion of resolving versus modeling which motivates the need for sub-scale modeling. The role that modeling assumptions play in 'hiding' our lack-of-knowledge about sub-scale phenomena is explained which leads to discussing uncertainty in simulations. It is argued that the uncertainty caused by resolution and modeling assumptions should be dealt with differently than uncertainty due to randomness or variability. The corollary is that a predictive capability cannot be defined solely as accuracy, or ability of predictions to match the available physical observations. We propose that 'predictability' is the demonstration that predictions from a class of 'equivalent' models are as consistent as possible. Equivalency stems from defining models that share a minimum requirement of accuracy, while being equally robust to the sources of lack-of-knowledge in the problem. Examples in computational physics and engineering are given to illustrate the discussion.
Abstract Objective: To identify the organizational factors which influence the diffusion of end user online literature searching, the computer-based patient record, and electronic mail systems in academic health sciences centers in the United States. Design: A total of 1335 individuals working in informatics and library areas at 67 academic health sciences centers in the U.S. were surveyed. Multivariate techniques were used to evaluate the relationship between the set of six organizational factors and two measures of innovation diffusion. Measurements: A Guttman-like scale was developed to measure infusion, or depth or sophistication, of each of the three innovations at each institution. Diffusion was measured by a question previously developed for another study. Six independent variables were measured via five formerly developed scales and one new one. Results: The overall response rate was 41%. The set of organizational variables produced significant results in the diffusion of each of the three innovations, with individual variables influencing diffusion to varying degrees. The same set produced significant results in relation to infusion only for online searching. There was little or no correlation between infusion and diffusion for each innovation. Conclusion: Organizational attributes are important predictors for diffusion of information technology innovations. Individual variables differ in their effect on each innovation. The set of attributes seems less able to predict infusion. It is recommended that both infusion and diffusion be measured in future studies because there is little relation between them. It is further recommended that individuals charged with implementing information technology in the health sciences receive training in managing organizational issues. PMID:9067876
While there has been a remarkable interest to make computer science a core K-12 academic subject in the United States, there is a shortage of K-12 computer science teachers to successfully implement computer sciences courses in schools. In order to enhance computer science teacher capacity, training programs have been offered through teacher professional development. In this study, the main goal was to systematically review the studies regarding computer science professional development to understand the scope, context, and effectiveness of these programs in the past decade (2004-2014). Based on 21 journal articles and conference proceedings, this study explored: (1) Type of professional development organization and source of funding, (2) professional development structure and participants, (3) goal of professional development and type of evaluation used, (4) specific computer science concepts and training tools used, (5) and their effectiveness to improve teacher practice and student learning.

In view of the changes in and growing variety of sports-related occupations, it is highly relevant for educational institutions to know how well the educational contents of their sport science courses meet the professional requirements. This study analyses the relationship between the competencies acquired through academic sports science courses and the requirements of the relevant jobs in Switzerland. The data for this empirical analysis were drawn from a sample of n = 1054 graduates of different academic sport science programmes at all eight Swiss universities. The results show that academic sport science courses primarily communicate sports-specific expertise and practical sports skills. On the other hand, most graduates consider that the acquisition of interdisciplinary competencies plays a comparatively minor role in sport science education, even though these competencies are felt to be an important requirement in a variety of work-related environments and challenges.

The Computational Materials Sciences Network (CMSN) is a virtual center consisting of scientists interested in working together, across organizational and disciplinary boundaries, to formulate and pursue projects that reflect challenging and relevant computational research in the materials sciences. The projects appropriate for this center involve those problems best pursued through broad cooperative efforts, rather than those key problems best tackled by single investigator groups. CMSN operates similarly to the DOE Center of Excellence for the Synthesis and Processing of Advanced Materials, coordinated by George Samara at Sandia. As in the Synthesis and Processing Center, the intent of the modest funding for CMSN is to foster partnering and collective activities. All CMSN proposals undergo external peer review and are judged foremost on the quality and timeliness of the science and also on criteria relevant to the objective of the center, especially concerning a strategy for partnering. More details about CMSN can be found on the CMSN webpages at: http://cmpweb.ameslab.gov/ccms/CMSN-homepage.html.

Scientific simulation, which provides a natural bridge between theory and experiment, is an essential tool for understanding complex plasma behaviour. Recent advances in simulations of magnetically confined plasmas are reviewed in this paper, with illustrative examples, chosen from associated research areas such as microturbulence, magnetohydrodynamics and other topics. Progress has been stimulated, in particular, by the exponential growth of computer speed along with significant improvements in computer technology. The advances in both particle and fluid simulations of fine-scale turbulence and large-scale dynamics have produced increasingly good agreement between experimental observations and computational modelling. This was enabled by two key factors: (a) innovative advances in analytic and computational methods for developing reduced descriptions of physics phenomena spanning widely disparate temporal and spatial scales and (b) access to powerful new computational resources. Excellent progress has been made in developing codes for which computer run-time and problem-size scale well with the number of processors on massively parallel processors (MPPs). Examples include the effective usage of the full power of multi-teraflop (multi-trillion floating point computations per second) MPPs to produce three-dimensional, general geometry, nonlinear particle simulations that have accelerated advances in understanding the nature of turbulence self-regulation by zonal flows. These calculations, which typically utilized billions of particles for thousands of time-steps, would not have been possible without access to powerful present generation MPP computers and the associated diagnostic and visualization capabilities. In looking towards the future, the current results from advanced simulations provide great encouragement for being able to include increasingly realistic dynamics to enable deeper physics insights into plasmas in both natural and laboratory environments.

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

In health science training, and medicine specifically, the gradual incorporation of technological developments has transformed the teaching and learning process, resulting in true "educational technology". The goal of this paper is to review the main features involved in these applications and highlight the main lines of research for the future. The results of peer reviewed literature published recently indicate the following features shared by the key technological developments in the field of health science education: first, development of simulation and visualization systems for a more complete and realistic representation of learning material over traditional paper format; second, portability and versatility of the applications, adapted for an increasing number of devices and operative systems; third, increasing focus on open source applications such as Massive Open Online Course (MOOC).

This article discusses the inherent flaws in considering and using the epistemology of the natural sciences as equivalent to a pedagogic basis for teaching and learning in the natural sciences. It begins with a discussion of the difference between practising science and learning to practice science. It follows with a discussion and refutation of three commonly held motives for using practicals in science education. It concludes with the presentation of three new, better motives for their use.

Presently, the solid earth sciences started to move towards implementing high performance computational (HPC) research facilities. One of the key tenants of HPC is performance, and designing a HPC solution tailored to a specific research field as solid earth that represents an optimum price/performance ratio is often a challenge. The HPC system performance strongly depends on the software-hardware interaction, and therefore prior knowledge on how well specific parallelized software performs on different HPC architectures can weight significantly on choosing the final configuration. In this paper we present benchmark results from two different HPC systems: one low-end HPCC (Horus) with 300 cores and 1.6 TFlops theoretical peak performance, and one high-end HPCC (CyberDyn) with 1344 cores and 11.2 TFlops theoretical peak performance. The software benchmark used in this paper is the open source package CitcomS, which is widely used in the solid earth community (www.geodynamics.org). Testing a CFD code specific for earth sciences, the HPC system Horus based on Gigabit Ethernet performed remarkably well compared with its counterpart Cyeberdyn which is based on Infiniband QDR fabric, but only for a relatively small number of computing cores (96). However, increasing the mesh size and the number of computing cores the HPCC CyberDyn starts outperforming the HPCC Horus because of the low-latency high-speed QDR network dedicated to MPI traffic. Since presently we are moving towards high-resolution simulations for geodynamic predictions that require the same scale as observations, HPC facilities used in earth sciences should benefit from larger up-front investment in future systems that are based on high-speed interconnects.
The Role Biomedical Science Laboratories Can Play In Improving Science Knowledge and Promoting First-Year Nursing Academic Success The need for additional nursing and health care professionals is expected to increase dramatically over the next 20 years. With this in mind, students must have strong biomedical science knowledge to be competent in their field. Some studies have shown that participation in bioscience laboratories can enhance science knowledge. If this is true, an analysis of the role bioscience labs have in first-year nursing academic success is apposite. In response, this study sought to determine whether concurrent enrollment in anatomy and microbiology lecture and lab courses improved final lecture course grades. The investigation was expanded to include a comparison of first-year nursing GPA and prerequisite bioscience concurrent lecture/lab enrollment. Additionally, research has indicated that learning is affected by student perception of the course, instructor, content, and environment. To gain an insight regarding students' perspectives of laboratory courses, almost 100 students completed a 20-statement perception survey to understand how lab participation affects learning. Data analyses involved comparing anatomy and microbiology final lecture course grades between students who concurrently enrolled in the lecture and lab courses and students who completed the lecture course alone. Independent t test analyses revealed that there was no significant difference between the groups for anatomy, t(285) = .11, p = .912, but for microbiology, the lab course provided a significant educational benefit, t(256) = 4.47, p = .000. However, when concurrent prerequisite bioscience lecture/lab enrollment was compared to non-concurrent enrollment for first-year nursing GPA using independent t test analyses, no significant difference was found for South Dakota State University, t(37) = -1.57, p = .125, or for the University of South Dakota, t(38) = -0.46, p

Enrollment in Computing Science university programs is at a dangerously low level. A major reason for this is the general lack of interest in Computing Science by females. In this paper, we discuss our experience with using a computer game construction environment as a vehicle to encourage female participation in Computing Science. Experiments…
Sociocultural theories of learning such as Wenger and Lave's situated learning have been suggested as alternatives to cognitive theories of learning like constructivism. This article examines situated learning within the context of computer science (CS) education. Situated learning accurately describes some CS communities like open-source software development, but it is not directly applicable to other CS communities, especially those that deal with non-CS application areas. Nevertheless, situated learning can inform CS education by analyzing debates on curriculum and pedagogy within this framework. CS educators should closely examine professional CS communities of practice and design educational activities to model the actual activities of those communities.

This study proposed and tested a model based on stereotype threat theory. The hypothesis is that women who are exposed to a low percentage of women in a science program are more likely to endorse the gender stereotype that science is a male domain, which will in turn undermine their autonomous academic motivation. A total of 167 women university…

This study focuses on the relationship between self-regulated learning behavior and their academic achievement of college students of science. For students of science, their involvement in motivational components is closely tied to their performance in the examinations. Cognitive strategies have the strongest influence on scores of the English achievement.

Some scholars view academic and industrial science as qualitatively different knowledge production regimes. Others claim that the two sectors are increasingly similar. Large-scale empirical evidence regarding similarities and differences, however, has been missing. Drawing on prior work on the organization of science, we first develop a framework…
