At the core of this framework is a taxonomy for discipline-specific entrepreneurship education content and learning goals—different educations have varying inherent strengths and weakness vis-à-vis entrepreneurship, and thus have different pathways and barriers to develop......Entrepreneurship education (E-Ed) is maturing—from debate about whether or not it can be done, to how it should be done (Katz, 2003; Kuratko, 2005); from business schools teaching start-ups through a business plan format, toward converging upon a broader attitudechanging framework (Mwasalwiba, 2010......, and the need for a tailored, discipline-specific approach to E-Ed is becoming rapidly apparent. As a first step toward differentiating E-Ed across disciplines, we propose the establishment of an E-Ed framework that can guide and align stakeholders, program designers, and educators in the construction...

Laboratory selection experiments are alluring in their simplicity, power, and ability to inform us about how evolution works. A longstanding challenge facing evolution experiments with metazoans is that significant generational turnover takes a long time. In this work, we present data from a unique system of experimentally evolved laboratory populations of Drosophila melanogaster that have experienced three distinct life-history selection regimes. The goal of our study was to determine how quickly populations of a certain selection regime diverge phenotypically from their ancestors, and how quickly they converge with independently derived populations that share a selection regime. Our results indicate that phenotypic divergence from an ancestral population occurs rapidly, within dozens of generations, regardless of that population's evolutionary history. Similarly, populations sharing a selection treatment converge on common phenotypes in this same time frame, regardless of selection pressures those populations may have experienced in the past. These patterns of convergence and divergence emerged much faster than expected, suggesting that intermediate evolutionary history has transient effects in this system. The results we draw from this system are applicable to other experimental evolution projects, and suggest that many relevant questions can be sufficiently tested on shorter timescales than previously thought. © 2016 The Author(s).

2018-01-31

In modern applications of molecular epidemiology, genetic sequence data are routinely used to identify clusters of transmission in rapidly evolving pathogens, most notably HIV-1. Traditional 'shoeleather' epidemiology infers transmission clusters by tracing chains of partners sharing epidemiological connections (e.g., sexual contact). Here, we present a computational tool for identifying a molecular transmission analog of such clusters: HIV-TRACE (TRAnsmission Cluster Engine). HIV-TRACE implements an approach inspired by traditional epidemiology, by identifying chains of partners whose viral genetic relatedness imply direct or indirect epidemiological connections. Molecular transmission clusters are constructed using codon-aware pairwise alignment to a reference sequence followed by pairwise genetic distance estimation among all sequences. This approach is computationally tractable and is capable of identifying HIV-1 transmission clusters in large surveillance databases comprising tens or hundreds of thousands of sequences in near real time, i.e., on the order of minutes to hours. HIV-TRACE is available at www.hivtrace.org and from github.com/veg/hivtrace, along with the accompanying result visualization module from github.com/veg/hivtrace-viz. Importantly, the approach underlying HIV-TRACE is not limited to the study of HIV-1 and can be applied to study outbreaks and epidemics of other rapidly evolving pathogens. © The Author 2018.

The apolipoprotein L family of programmed cell death and immunity genes rapidly evolved in primates at discrete sites of host-pathogen interactions.

Science.gov (United States)

Smith, Eric E; Malik, Harmit S

2009-05-01

Apolipoprotein L1 (APOL1) is a human protein that confers immunity to Trypanosoma brucei infections but can be countered by a trypanosome-encoded antagonist SRA. APOL1 belongs to a family of programmed cell death genes whose proteins can initiate host apoptosis or autophagic death. We report here that all six members of the APOL gene family (APOL1-6) present in humans have rapidly evolved in simian primates. APOL6, furthermore, shows evidence of an adaptive sweep during recent human evolution. In each APOL gene tested, we found rapidly evolving codons in or adjacent to the SRA-interacting protein domain (SID), which is the domain of APOL1 that interacts with SRA. In APOL6, we also found a rapidly changing 13-amino-acid cluster in the membrane-addressing domain (MAD), which putatively functions as a pH sensor and regulator of cell death. We predict that APOL genes are antagonized by pathogens by at least two distinct mechanisms: SID antagonists, which include SRA, that interact with the SID of various APOL proteins, and MAD antagonists that interact with the MAD hinge base of APOL6. These antagonists either block or prematurely cause APOL-mediated programmed cell death of host cells to benefit the infecting pathogen. These putative interactions must occur inside host cells, in contrast to secreted APOL1 that trafficks to the trypanosome lysosome. Hence, the dynamic APOL gene family appears to be an important link between programmed cell death of host cells and immunity to pathogens.

The Virtual Learning Commons (VLC): Enabling Co-Innovation Across Disciplines

2014-12-01

A key challenge for scientists addressing grand-challenge problems is identifying, understanding, and integrating potentially relevant methods, models and tools that that are rapidly evolving in the informatics community. Such tools are essential for effectively integrating data and models in complex research projects, yet it is often difficult to know what tools are available and it is not easy to understand or evaluate how they might be used in a given research context. The goal of the National Science Foundation-funded Virtual Learning Commons (VLC) is to improve awareness and understanding of emerging methodologies and technologies, facilitate individual and group evaluation of these, and trace the impact of innovations within and across teams, disciplines, and communities. The VLC is a Web-based social bookmarking site designed specifically to support knowledge exchange in research communities. It is founded on well-developed models of technology adoption, diffusion of innovation, and experiential learning. The VLC makes use of Web 2.0 (Social Web) and Web 3.0 (Semantic Web) approaches. Semantic Web approaches enable discovery of potentially relevant methods, models, and tools, while Social Web approaches enable collaborative learning about their function. The VLC is under development and the first release is expected Fall 2014.

Full Text Available The use of quantitative metrics to gauge the impact of scholarly publications, authors, and disciplines is predicated on the availability of reliable usage and annotation data. Citation and download counts are widely available from digital libraries. However, current annotation systems rely on proprietary labels, refer to journals but not articles or authors, and are manually curated. To address these limitations, we propose a social framework based on crowdsourced annotations of scholars, designed to keep up with the rapidly evolving disciplinary and interdisciplinary landscape. We describe a system called Scholarometer, which provides a service to scholars by computing citation-based impact measures. This creates an incentive for users to provide disciplinary annotations of authors, which in turn can be used to compute disciplinary metrics. We first present the system architecture and several heuristics to deal with noisy bibliographic and annotation data. We report on data sharing and interactive visualization services enabled by Scholarometer. Usage statistics, illustrating the data collected and shared through the framework, suggest that the proposed crowdsourcing approach can be successful. Secondly, we illustrate how the disciplinary bibliometric indicators elicited by Scholarometer allow us to implement for the first time a universal impact measure proposed in the literature. Our evaluation suggests that this metric provides an effective means for comparing scholarly impact across disciplinary boundaries.

Natural selection promotes antigenic evolvability.

2013-01-01

The hypothesis that evolvability - the capacity to evolve by natural selection - is itself the object of natural selection is highly intriguing but remains controversial due in large part to a paucity of direct experimental evidence. The antigenic variation mechanisms of microbial pathogens provide an experimentally tractable system to test whether natural selection has favored mechanisms that increase evolvability. Many antigenic variation systems consist of paralogous unexpressed 'cassettes' that recombine into an expression site to rapidly alter the expressed protein. Importantly, the magnitude of antigenic change is a function of the genetic diversity among the unexpressed cassettes. Thus, evidence that selection favors among-cassette diversity is direct evidence that natural selection promotes antigenic evolvability. We used the Lyme disease bacterium, Borrelia burgdorferi, as a model to test the prediction that natural selection favors amino acid diversity among unexpressed vls cassettes and thereby promotes evolvability in a primary surface antigen, VlsE. The hypothesis that diversity among vls cassettes is favored by natural selection was supported in each B. burgdorferi strain analyzed using both classical (dN/dS ratios) and Bayesian population genetic analyses of genetic sequence data. This hypothesis was also supported by the conservation of highly mutable tandem-repeat structures across B. burgdorferi strains despite a near complete absence of sequence conservation. Diversification among vls cassettes due to natural selection and mutable repeat structures promotes long-term antigenic evolvability of VlsE. These findings provide a direct demonstration that molecular mechanisms that enhance evolvability of surface antigens are an evolutionary adaptation. The molecular evolutionary processes identified here can serve as a model for the evolution of antigenic evolvability in many pathogens which utilize similar strategies to establish chronic infections.

Classification of the history of science has a long history, and the essays in this Focus section explore that history and its consequences from several different angles. Two of the papers deal with how classifying schemes in bibliography have evolved. A third looks at the way archival organization has changed over the years. Finally, the last essay explores the intersection of human and machine classifying systems. All four contributions look closely at the ramifications of the digital revolution for the way we organize the knowledge of the discipline.

Sex as a strategy against rapidly evolving parasites.

Auld, Stuart K J R; Tinkler, Shona K; Tinsley, Matthew C

2016-12-28

Why is sex ubiquitous when asexual reproduction is much less costly? Sex disrupts coadapted gene complexes; it also causes costs associated with mate finding and the production of males who do not themselves bear offspring. Theory predicts parasites select for host sex, because genetically variable offspring can escape infection from parasites adapted to infect the previous generations. We examine this using a facultative sexual crustacean, Daphnia magna, and its sterilizing bacterial parasite, Pasteuria ramosa We obtained sexually and asexually produced offspring from wild-caught hosts and exposed them to contemporary parasites or parasites isolated from the same population one year later. We found rapid parasite adaptation to replicate within asexual but not sexual offspring. Moreover, sexually produced offspring were twice as resistant to infection as asexuals when exposed to parasites that had coevolved alongside their parents (i.e. the year two parasite). This fulfils the requirement that the benefits of sex must be both large and rapid for sex to be favoured by selection. © 2016 The Author(s).

The Comet Cometh: Evolving Developmental Systems.

Jaeger, Johannes; Laubichler, Manfred; Callebaut, Werner

In a recent opinion piece, Denis Duboule has claimed that the increasing shift towards systems biology is driving evolutionary and developmental biology apart, and that a true reunification of these two disciplines within the framework of evolutionary developmental biology (EvoDevo) may easily take another 100 years. He identifies methodological, epistemological, and social differences as causes for this supposed separation. Our article provides a contrasting view. We argue that Duboule's prediction is based on a one-sided understanding of systems biology as a science that is only interested in functional, not evolutionary, aspects of biological processes. Instead, we propose a research program for an evolutionary systems biology, which is based on local exploration of the configuration space in evolving developmental systems. We call this approach-which is based on reverse engineering, simulation, and mathematical analysis-the natural history of configuration space. We discuss a number of illustrative examples that demonstrate the past success of local exploration, as opposed to global mapping, in different biological contexts. We argue that this pragmatic mode of inquiry can be extended and applied to the mathematical analysis of the developmental repertoire and evolutionary potential of evolving developmental mechanisms and that evolutionary systems biology so conceived provides a pragmatic epistemological framework for the EvoDevo synthesis.

Rapid response systems.

2018-07-01

Rapid response systems are commonly employed by hospitals to identify and respond to deteriorating patients outside of the intensive care unit. Controversy exists about the benefits of rapid response systems. We aimed to review the current state of the rapid response literature, including evolving aspects of afferent (risk detection) and efferent (intervention) arms, outcome measurement, process improvement, and implementation. Articles written in English and published in PubMed. Rapid response systems are heterogeneous, with important differences among afferent and efferent arms. Clinically meaningful outcomes may include unexpected mortality, in-hospital cardiac arrest, length of stay, cost, and processes of care at end of life. Both positive and negative interventional studies have been published, although the two largest randomized trials involving rapid response systems - the Medical Early Response and Intervention Trial (MERIT) and the Effect of a Pediatric Early Warning System on All-Cause Mortality in Hospitalized Pediatric Patients (EPOCH) trial - did not find a mortality benefit with these systems, albeit with important limitations. Advances in monitoring technologies, risk assessment strategies, and behavioral ergonomics may offer opportunities for improvement. Rapid responses may improve some meaningful outcomes, although these findings remain controversial. These systems may also improve care for patients at the end of life. Rapid response systems are expected to continue evolving with novel developments in monitoring technologies, risk prediction informatics, and work in human factors. Copyright © 2018 Elsevier B.V.

Winkler, Jennifer L; Walsh, Michele E; de Blois, Madeleine; Maré, Jeannette; Carvajal, Scott C

2017-06-01

This formative evaluation develops a novel conceptual model for a discipline approach fostering intrinsic motivation and positive relationships in schools. We used concept mapping to elicit and integrate perspectives on kind discipline from teachers, administrators, and other school staff. Three core themes describing kind discipline emerged from 11 identified clusters: (1) proactively developing a positive school climate, (2) responding to conflict with empathy, accountability, and skill, and (3) supporting staff skills in understanding and sharing expectations. We mapped the identified components of kind discipline onto a social ecological model and found that kind discipline encompasses all levels of that model including the individual, relational, environmental/structural, and even community levels. This contrasts with the dominant individual-behavioral discipline approaches that focus on fewer levels and may not lead to sustained student and staff motivation. The findings illustrate the importance of setting and communicating clear expectations and the need for them to be collaboratively developed. Products of the analysis and synthesis reported here are operationalized materials for teachers grounded in a "be kind" culture code for classrooms. Copyright © 2017 Elsevier Ltd.

The rapidly evolving centromere-specific histone has stringent functional requirements in Arabidopsis thaliana.

Centromeres control chromosome inheritance in eukaryotes, yet their DNA structure and primary sequence are hypervariable. Most animals and plants have megabases of tandem repeats at their centromeres, unlike yeast with unique centromere sequences. Centromere function requires the centromere-specific histone CENH3 (CENP-A in human), which replaces histone H3 in centromeric nucleosomes. CENH3 evolves rapidly, particularly in its N-terminal tail domain. A portion of the CENH3 histone-fold domain, the CENP-A targeting domain (CATD), has been previously shown to confer kinetochore localization and centromere function when swapped into human H3. Furthermore, CENP-A in human cells can be functionally replaced by CENH3 from distantly related organisms including Saccharomyces cerevisiae. We have used cenh3-1 (a null mutant in Arabidopsis thaliana) to replace endogenous CENH3 with GFP-tagged variants. A H3.3 tail domain-CENH3 histone-fold domain chimera rescued viability of cenh3-1, but CENH3's lacking a tail domain were nonfunctional. In contrast to human results, H3 containing the A. thaliana CATD cannot complement cenh3-1. GFP-CENH3 from the sister species A. arenosa functionally replaces A. thaliana CENH3. GFP-CENH3 from the close relative Brassica rapa was targeted to centromeres, but did not complement cenh3-1, indicating that kinetochore localization and centromere function can be uncoupled. We conclude that CENH3 function in A. thaliana, an organism with large tandem repeat centromeres, has stringent requirements for functional complementation in mitosis.

De novo ORFs in Drosophila are important to organismal fitness and evolved rapidly from previously non-coding sequences.

Directory of Open Access Journals (Sweden)

Josephine A Reinhardt

Full Text Available How non-coding DNA gives rise to new protein-coding genes (de novo genes is not well understood. Recent work has revealed the origins and functions of a few de novo genes, but common principles governing the evolution or biological roles of these genes are unknown. To better define these principles, we performed a parallel analysis of the evolution and function of six putatively protein-coding de novo genes described in Drosophila melanogaster. Reconstruction of the transcriptional history of de novo genes shows that two de novo genes emerged from novel long non-coding RNAs that arose at least 5 MY prior to evolution of an open reading frame. In contrast, four other de novo genes evolved a translated open reading frame and transcription within the same evolutionary interval suggesting that nascent open reading frames (proto-ORFs, while not required, can contribute to the emergence of a new de novo gene. However, none of the genes arose from proto-ORFs that existed long before expression evolved. Sequence and structural evolution of de novo genes was rapid compared to nearby genes and the structural complexity of de novo genes steadily increases over evolutionary time. Despite the fact that these genes are transcribed at a higher level in males than females, and are most strongly expressed in testes, RNAi experiments show that most of these genes are essential in both sexes during metamorphosis. This lethality suggests that protein coding de novo genes in Drosophila quickly become functionally important.

Disciplined by the discipline: a social-epistemic fingerprint of the history of science.

Vanderstraeten, Raf; Vandermoere, Frederic

2015-06-01

The scientific system is primarily differentiated into disciplines. While disciplines may be wide in scope and diverse in their research practices, they serve scientific communities that evaluate research and also grant recognition to what is published. The analysis of communication and publication practices within such a community hence allows us to shed light on the dynamics of this discipline. On the basis of an empirical analysis of Isis, we show how the process of discipline-building in history of science has led its practitioners to be socialized and sensitized in relatively strong intra-disciplinary terms--with minimal interdisciplinary openness.

Concurrent approach for evolving compact decision rule sets

Science.gov (United States)

Marmelstein, Robert E.; Hammack, Lonnie P.; Lamont, Gary B.

1999-02-01

The induction of decision rules from data is important to many disciplines, including artificial intelligence and pattern recognition. To improve the state of the art in this area, we introduced the genetic rule and classifier construction environment (GRaCCE). It was previously shown that GRaCCE consistently evolved decision rule sets from data, which were significantly more compact than those produced by other methods (such as decision tree algorithms). The primary disadvantage of GRaCCe, however, is its relatively poor run-time execution performance. In this paper, a concurrent version of the GRaCCE architecture is introduced, which improves the efficiency of the original algorithm. A prototype of the algorithm is tested on an in- house parallel processor configuration and the results are discussed.

Evolving fuzzy rules for relaxed-criteria negotiation.

Science.gov (United States)

Sim, Kwang Mong

2008-12-01

In the literature on automated negotiation, very few negotiation agents are designed with the flexibility to slightly relax their negotiation criteria to reach a consensus more rapidly and with more certainty. Furthermore, these relaxed-criteria negotiation agents were not equipped with the ability to enhance their performance by learning and evolving their relaxed-criteria negotiation rules. The impetus of this work is designing market-driven negotiation agents (MDAs) that not only have the flexibility of relaxing bargaining criteria using fuzzy rules, but can also evolve their structures by learning new relaxed-criteria fuzzy rules to improve their negotiation outcomes as they participate in negotiations in more e-markets. To this end, an evolutionary algorithm for adapting and evolving relaxed-criteria fuzzy rules was developed. Implementing the idea in a testbed, two kinds of experiments for evaluating and comparing EvEMDAs (MDAs with relaxed-criteria rules that are evolved using the evolutionary algorithm) and EMDAs (MDAs with relaxed-criteria rules that are manually constructed) were carried out through stochastic simulations. Empirical results show that: 1) EvEMDAs generally outperformed EMDAs in different types of e-markets and 2) the negotiation outcomes of EvEMDAs generally improved as they negotiated in more e-markets.

2012-12-01

As part of a larger organizational study, we sought to survey biobanks in the United States. However, we encountered two problems with this population. First, no common definition of biobanks exists. Second, no census is available of these facilities from which to sample in order to implement a survey. In light of these problems, we employed a multifaceted approach using electronic searches of PubMed, RePORTER, and Google. In addition, we systematically searched for biobanks housed within universities that have NIH-designated Clinical and Translational Science Awards (CTSA). We expanded this part of the search by looking for biobanks among all members of the American Association of Medical Colleges (AAMC). Finally, we added banks to our database found previously by other researchers and banks found via correspondence with our colleagues. Our search strategy produced a database of 624 biobanks for which we were able to confirm contact information in order to conduct our online survey. Another 140 biobanks were identified but did not respond to our requests to confirm their existence or contact information. In order to maximize both the uniqueness of banks found and the greatest return on effort for each search, we suggest targeting resources that are already organized. In our work, these included the CTSA, AAMC, and part of the Google searches. We contend that our search provides a model for analysis of new fields of research and/or rapidly evolving industries. Furthermore, our approach demonstrates that with the appropriate tools it is possible to develop a systematic and comprehensive database to investigate undefined populations.

Complex networks have emerged as a simple yet powerful framework to represent and analyze a wide range of complex systems. The problem of ranking the nodes and the edges in complex networks is critical for a broad range of real-world problems because it affects how we access online information and products, how success and talent are evaluated in human activities, and how scarce resources are allocated by companies and policymakers, among others. This calls for a deep understanding of how existing ranking algorithms perform, and which are their possible biases that may impair their effectiveness. Many popular ranking algorithms (such as Google's PageRank) are static in nature and, as a consequence, they exhibit important shortcomings when applied to real networks that rapidly evolve in time. At the same time, recent advances in the understanding and modeling of evolving networks have enabled the development of a wide and diverse range of ranking algorithms that take the temporal dimension into account. The aim of this review is to survey the existing ranking algorithms, both static and time-aware, and their applications to evolving networks. We emphasize both the impact of network evolution on well-established static algorithms and the benefits from including the temporal dimension for tasks such as prediction of network traffic, prediction of future links, and identification of significant nodes.

Problems of discipline are common among parents. These may be the results of the parents' pitfalls in disciplining their children. To find out common pitfalls of parents in disciplining their children. Parents of students with ages ranged between 60-72 months old in Bangkok-Noi district, Bangkok, were selected by random sampling. Total number of 1947 children ages between 60-72 months were recruited. Parents of these children were interviewed with a questionnaire designed to probe into problems in child rearing. There hindered and fifty questionnaires were used for data analyses. Parents had high concerns about problems in discipline their children and needed support from professional personnel. They had limited knowledge and possessed lots of wrong attitude towards discipline. Common pitfalls on the topics were problems in, 1) limit setting 2) rewarding and punishment 3) supervision on children watching TV and bedtime routines. Parents of children with ages 60-72 months old in Bangkok-Noi district, Bangkok, had several common pitfalls in disciplining their children, including attitude, knowledge and practice.

VARIETIES OF SOCIAL DISCIPLINING, HISTORICAL PERSPECTIVES.

Directory of Open Access Journals (Sweden)

Tomás A. Mantecón Movellán

2011-04-01

Full Text Available Historical thought has tended to explain social disciplining according to two main analytical perspectives: on one hand, German tradition about the so-called sozialdisziplinierung and, on the other hand, Foucault perspectives (focussed on disciplines practiced on the bodies-and/or-minds of people by the authorities. From these both viewpoints social disciplining was a dynamic ingredient of change, from traditional societies up to contemporary liberal societies; a machinery to provoke top-down changes (from above. On the bases of historical evidences, this research claims for a third viewpoint that stresses dynamics of social discipline and social disciplining from below; underlines the need of integrating this third perspective in the historical explanation of change in past societies throughout the analysis of social practices of everyday life; the values underneath them and, in the end, taking into account varieties of discipline and perspectives of social disciplining from below.

"A mission-driven discipline": the growth of conservation biology.

Meine, Curt; Soulé, Michael; Noss, Reed E

2006-06-01

Conservation biology emerged in the mid-1980s, drawing on established disciplines and integrating them in pursuit of a coherent goal: the protection and perpetuation of the Earth's biological diversity. Opportunistic in its borrowing and application of knowledge, conservation biology had its roots within the established biological sciences and resource management disciplines but has continually incorporated insights from the empirical experience of resource managers, from the social sciences and humanities, and from diverse cultural sources. The Society for Conservation Biology (SCB) has represented the field's core constituency, while expanding that constituency in keeping with the field's integrative spirit. Conservation Biology has served as SCB's flagship publication, promoting research, dialog, debate, and application of the field's essential concepts. Over the last 20 years the field, SCB, and the journal have evolved to meet changing conservation needs, to explore gaps in our knowledge base, to incorporate new information from related fields, to build professional capacity, and to provide expanded opportunities for international participation. In turn, the field, SCB, and journal have prompted change in related fields, organizations, and publications. In its dedication to advancing the scientific foundations of biodiversity conservation and placing that science at the service of society in a world whose variety, wildness, and beauty we care for conservation biology represents both a continuation and radical reconfiguration of the traditional relationship between science and conservation.

Environmental Noise, Genetic Diversity and the Evolution of Evolvability and Robustness in Model Gene Networks

Science.gov (United States)

Steiner, Christopher F.

2012-01-01

The ability of organisms to adapt and persist in the face of environmental change is accepted as a fundamental feature of natural systems. More contentious is whether the capacity of organisms to adapt (or “evolvability”) can itself evolve and the mechanisms underlying such responses. Using model gene networks, I provide evidence that evolvability emerges more readily when populations experience positively autocorrelated environmental noise (red noise) compared to populations in stable or randomly varying (white noise) environments. Evolvability was correlated with increasing genetic robustness to effects on network viability and decreasing robustness to effects on phenotypic expression; populations whose networks displayed greater viability robustness and lower phenotypic robustness produced more additive genetic variation and adapted more rapidly in novel environments. Patterns of selection for robustness varied antagonistically with epistatic effects of mutations on viability and phenotypic expression, suggesting that trade-offs between these properties may constrain their evolutionary responses. Evolution of evolvability and robustness was stronger in sexual populations compared to asexual populations indicating that enhanced genetic variation under fluctuating selection combined with recombination load is a primary driver of the emergence of evolvability. These results provide insight into the mechanisms potentially underlying rapid adaptation as well as the environmental conditions that drive the evolution of genetic interactions. PMID:23284934

The way we get our funding, collaborate, do our research, and get the word out has evolved over hundreds of years but we can imagine a more open science world, largely facilitated by the internet. The movement towards this more open way of doing and presenting science is coming, and it is not taking hundreds of years. If you are interested in these trends, and would like to find out more about where this is all headed and what it means to you, consider downloding Opening Science, edited by Sönke Bartling and Sascha Friesike, subtitled The Evolving Guide on How the Internet is Changing Research, Collaboration, and Scholarly Publishing. In 26 chapters by various authors from a range of disciplines the book explores the developing world of open science, starting from the first scientific revolution and bringing us to the next scientific revolution, sometimes referred to as “Science 2.0”. Some of the articles deal with the impact of the changing landscape of how science is done, looking at the impact of open science on Academia, or journal publishing, or medical research. Many of the articles look at the uses, pitfalls, and impact of specific tools, like microblogging (think Twitter), social networking, and reference management. There is lots of discussion and definition of terms you might use or misuse like “altmetrics” and “impact factor”. Science will probably never be completely open, and Twitter will probably never replace the journal article,

Evolving approaches to the ethical management of genomic data.

Science.gov (United States)

McEwen, Jean E; Boyer, Joy T; Sun, Kathie Y

2013-06-01

The ethical landscape in the field of genomics is rapidly shifting. Plummeting sequencing costs, along with ongoing advances in bioinformatics, now make it possible to generate an enormous volume of genomic data about vast numbers of people. The informational richness, complexity, and frequently uncertain meaning of these data, coupled with evolving norms surrounding the sharing of data and samples and persistent privacy concerns, have generated a range of approaches to the ethical management of genomic information. As calls increase for the expanded use of broad or even open consent, and as controversy grows about how best to handle incidental genomic findings, these approaches, informed by normative analysis and empirical data, will continue to evolve alongside the science.

of evolvable digital phenotypes. Although some types of selection in evolutionary computation indirectly encourage evolvability, one unexplored possibility is to directly select for evolvability. To do so, we estimate an individual's future potential for diversity by calculating the behavioral diversity of its...... immediate offspring, and select organisms with increased offspring variation. While the technique is computationally expensive, we hypothesized that direct selection would better encourage evolvability than indirect methods. Experiments in two evolutionary robotics domains confirm this hypothesis: in both...... domains, such Evolvability Search produces solutions with higher evolvability than those produced with Novelty Search or traditional objective-based search algorithms.

Translational neonatology research: transformative encounters across species and disciplines.

Dam, Mie S; Sangild, Per T; Svendsen, Mette N

2018-01-22

This paper explores the laborious and intimate work of turning bodies of research animals into models of human patients. Based on ethnographic research in the interdisciplinary Danish research centre NEOMUNE, we investigate collaboration across species and disciplines, in research aiming at improving survival for preterm infants. NEOMUNE experimental studies on piglets evolved as a platform on which both basic and clinical scientists exercised professional authority. Guided by the field of multi-species research, we explore the social and material agency of research animals in the production of human health. Drawing on Anna Tsing's concept of "collaborative survival", we show that sharing the responsibility of the life and death of up to twenty-five preterm piglets fostered not only a collegial solidarity between basic and clinical scientists, but also a transformative cross-fertilization across species and disciplines-a productive "contamination"-facilitating the day-to-day survival of piglets, the academic survival of scientists and the promise of survival of preterm infants. Contamination spurred intertwined identity shifts that increased the porosity between the pig laboratory and the neonatal intensive care unit. Of particular significance was the ability of the research piglets to flexibly become animal-infant-patient hybrids in need of a united effort from basic and clinical researchers. However, 'hybrid pigs' also entailed a threat to the demarcation between humans and animals that consolidates the use of animals in biomedical research, and efforts were continuously done to keep contamination within spatial limits. We conclude that contamination facilitates transformative encounters, yet needs spatial containment to materialize bench-to-bedside translation.

Whole-genome sequencing of a laboratory-evolved yeast strain

Dunham Maitreya J

2010-02-01

Full Text Available Abstract Background Experimental evolution of microbial populations provides a unique opportunity to study evolutionary adaptation in response to controlled selective pressures. However, until recently it has been difficult to identify the precise genetic changes underlying adaptation at a genome-wide scale. New DNA sequencing technologies now allow the genome of parental and evolved strains of microorganisms to be rapidly determined. Results We sequenced >93.5% of the genome of a laboratory-evolved strain of the yeast Saccharomyces cerevisiae and its ancestor at >28× depth. Both single nucleotide polymorphisms and copy number amplifications were found, with specific gains over array-based methodologies previously used to analyze these genomes. Applying a segmentation algorithm to quantify structural changes, we determined the approximate genomic boundaries of a 5× gene amplification. These boundaries guided the recovery of breakpoint sequences, which provide insights into the nature of a complex genomic rearrangement. Conclusions This study suggests that whole-genome sequencing can provide a rapid approach to uncover the genetic basis of evolutionary adaptations, with further applications in the study of laboratory selections and mutagenesis screens. In addition, we show how single-end, short read sequencing data can provide detailed information about structural rearrangements, and generate predictions about the genomic features and processes that underlie genome plasticity.

Rapidly evolving zona pellucida domain proteins are a major component of the vitelline envelope of abalone eggs

Science.gov (United States)

Aagaard, Jan E.; Yi, Xianhua; MacCoss, Michael J.; Swanson, Willie J.

2006-01-01

Proteins harboring a zona pellucida (ZP) domain are prominent components of vertebrate egg coats. Although less well characterized, the egg coat of the non-vertebrate marine gastropod abalone (Haliotis spp.) is also known to contain a ZP domain protein, raising the possibility of a common molecular basis of metazoan egg coat structures. Egg coat proteins from vertebrate as well as non-vertebrate taxa have been shown to evolve under positive selection. Studied most extensively in the abalone system, coevolution between adaptively diverging egg coat and sperm proteins may contribute to the rapid development of reproductive isolation. Thus, identifying the pattern of evolution among egg coat proteins is important in understanding the role these genes may play in the speciation process. The purpose of the present study is to characterize the constituent proteins of the egg coat [vitelline envelope (VE)] of abalone eggs and to provide preliminary evidence regarding how selection has acted on VE proteins during abalone evolution. A proteomic approach is used to match tandem mass spectra of peptides from purified VE proteins with abalone ovary EST sequences, identifying 9 of 10 ZP domain proteins as components of the VE. Maximum likelihood models of codon evolution suggest positive selection has acted among a subset of amino acids for 6 of these genes. This work provides further evidence of the prominence of ZP proteins as constituents of the egg coat, as well as the prominent role of positive selection in diversification of these reproductive proteins.

Sensationalistic journalism and tales of snakebite: are rattlesnakes rapidly evolving more toxic venom?

Science.gov (United States)

Hayes, William K; Mackessy, Stephen P

2010-03-01

Recent reports in the lay press have suggested that bites by rattlesnakes in the last several years have been more severe than those in the past. The explanation, often citing physicians, is that rattlesnakes are evolving more toxic venom, perhaps in response to anthropogenic causes. We suggest that other explanations are more parsimonious, including factors dependent on the snake and factors associated with the bite victim's response to envenomation. Although bites could become more severe from an increased proportion of bites from larger or more provoked snakes (ie, more venom injected), the venom itself evolves much too slowly to explain the severe symptoms occasionally seen. Increased snakebite severity could also result from a number of demographic changes in the victim profile, including age and body size, behavior toward the snake (provocation), anatomical site of bite, clothing, and general health including asthma prevalence and sensitivity to foreign antigens. Clinical management of bites also changes perpetually, rendering comparisons of snakebite severity over time tenuous. Clearly, careful study taking into consideration many factors will be essential to document temporal changes in snakebite severity or venom toxicity. Presently, no published evidence for these changes exists. The sensationalistic coverage of these atypical bites and accompanying speculation is highly misleading and can produce many detrimental results, such as inappropriate fear of the outdoors and snakes, and distraction from proven snakebite management needs, including a consistent supply of antivenom, adequate health care, and training. We urge healthcare providers to avoid propagating misinformation about snakes and snakebites. Copyright (c) 2010 Wilderness Medical Society. Published by Elsevier Inc. All rights reserved.

Childhood discipline: challenges for clinicians and parents.

Science.gov (United States)

Banks, J Burton

2002-10-15

Although childhood discipline is an important issue for parents, this topic is seldom emphasized by family physicians during well-child examinations. Behavior problems are relatively common but frequently under-recognized by physicians. Opportunities to counsel parents about safe, effective methods of discipline are therefore missed. Discipline should be instructive and age-appropriate and should include positive reinforcement for good behavior. Punishment is only one aspect of discipline and, in order to be effective, it must be prompt, consistent, and fair. Time-out is frequently used to correct younger children, but because it is often enforced improperly, it loses its effectiveness. Corporal punishment is a controversial but common form of discipline that is less effective than some other types of punishment. Its use is linked to child and spouse abuse, as well as to future substance use, violent crime, poor self-esteem, and depression. Despite the possible negative effects of corporal punishment, it is still widely accepted in our society. Since discipline plays an important role in the social and emotional development of children, physicians should be trained to discuss this issue with parents during routine well-child examinations.

Parenting classes: focus on discipline.

Science.gov (United States)

Campbell, J M

1992-01-01

Nurses in community settings have an opportunity to provide instruction related to health and life-style needs. An important consideration is the parental role. A particularly controversial and opinion-laden aspect of parenting is disciplining children. Discipline provides children with the security of clearly enforced rules to help them learn self-control and social standards. Parenting classes are worthwhile for people who have little formal or informal preparation. A survey of middle-class elementary school district parents' and childrens' attitudes toward discipline was conducted to develop meaningful parenting classes. Parents' feelings about being a mother or father were surprisingly negative. A parent educational program was developed to cover child growth and development and disciplinary practices. Parent evaluations led to continuation and an expansion of this program to other schools within the area.

Toward a general ontology for digital forensic disciplines.

Science.gov (United States)

Karie, Nickson M; Venter, Hein S

2014-09-01

Ontologies are widely used in different disciplines as a technique for representing and reasoning about domain knowledge. However, despite the widespread ontology-related research activities and applications in different disciplines, the development of ontologies and ontology research activities is still wanting in digital forensics. This paper therefore presents the case for establishing an ontology for digital forensic disciplines. Such an ontology would enable better categorization of the digital forensic disciplines, as well as assist in the development of methodologies and specifications that can offer direction in different areas of digital forensics. This includes such areas as professional specialization, certifications, development of digital forensic tools, curricula, and educational materials. In addition, the ontology presented in this paper can be used, for example, to better organize the digital forensic domain knowledge and explicitly describe the discipline's semantics in a common way. Finally, this paper is meant to spark discussions and further research on an internationally agreed ontological distinction of the digital forensic disciplines. Digital forensic disciplines ontology is a novel approach toward organizing the digital forensic domain knowledge and constitutes the main contribution of this paper. © 2014 American Academy of Forensic Sciences.

First-generation Korean-American parents' perceptions of discipline.

Kim, Eunjung; Hong, Seunghye

2007-01-01

Nurses not only need to be familiar with professional guidelines of discipline and but also need to be aware of variances in styles of acceptable discipline across cultural groups. The goal of this study was to explore cultural influences in relation to (1) first-generation Korean-American parents' perceptions of common discipline strategies in the United States, and (2) discipline strategies commonly used among first-generation Korean-American parents. Inductive content analysis was used to analyze interview data from seven first-generation Korean-American parents. Derived themes indicated that parents considered spanking/hitting and less hugging/kissing as Korean style, and time-out, use of sticker charts, hugging/kissing, removing/adding privileges, and giving chores as American style. Recent immigrant parents were not familiar with common positive discipline strategies in the United States. As they adapted to mainstream society, they discontinued what they perceived to be negative aspects of Korean style and adopted positive aspects of American style. They were sensitive to children's views on discipline, and they experienced communication difficulties with children. These findings indicated that Korean-American parents' perceptions of discipline strategies were shaped by living in two cultures and were different from western viewpoints.

Analysis of expression in the Anopheles gambiae developing testes reveals rapidly evolving lineage-specific genes in mosquitoes

Krzywinski Jaroslaw

2009-07-01

Full Text Available Abstract Background Male mosquitoes do not feed on blood and are not involved in delivery of pathogens to humans. Consequently, they are seldom the subjects of research, which results in a very poor understanding of their biology. To gain insights into male developmental processes we sought to identify genes transcribed exclusively in the reproductive tissues of male Anopheles gambiae pupae. Results Using a cDNA subtraction strategy, five male-specifically or highly male-biased expressed genes were isolated, four of which remain unannotated in the An. gambiae genome. Spatial and temporal expression patterns suggest that each of these genes is involved in the mid-late stages of spermatogenesis. Their sequences are rapidly evolving; however, two genes possess clear homologs in a wide range of taxa and one of these probably acts in a sperm motility control mechanism conserved in many organisms, including humans. The other three genes have no match to sequences from non-mosquito taxa, thus can be regarded as orphans. RNA in situ hybridization demonstrated that one of the orphans is transcribed in spermatids, which suggests its involvement in sperm maturation. Two other orphans have unknown functions. Expression analysis of orthologs of all five genes indicated that male-biased transcription was not conserved in the majority of cases in Aedes and Culex. Conclusion Discovery of testis-expressed orphan genes in mosquitoes opens new prospects for the development of innovative control methods. The orphan encoded proteins may represent unique targets of selective anti-mosquito sterilizing agents that will not affect non-target organisms.

To gain insights into male developmental processes we sought to identify genes transcribed exclusively in the reproductive tissues of male Anopheles gambiae pupae. Using a cDNA subtraction strategy, five male-specifically or highly male-biased expressed genes were isolated, four of which remain unannotated in the An. gambiae genome. Spatial and temporal expression patterns suggest that each of these genes is involved in the mid-late stages of spermatogenesis. Their sequences are rapidly evolving; however, two genes possess clear homologs in a wide range of taxa and one of these probably acts in a sperm motility control mechanism conserved in many organisms, including humans. The other three genes have no match to sequences from non-mosquito taxa, thus can be regarded as orphans. RNA in situ hybridization demonstrated that one of the orphans is transcribed in spermatids, which suggests its involvement in sperm maturation. Two other orphans have unknown functions. Expression analysis of orthologs of all five genes indicated that male-biased transcription was not conserved in the majority of cases in Aedes and Culex. Discovery of testis-expressed orphan genes in mosquitoes opens new prospects for the development of innovative control methods. The orphan encoded proteins may represent unique targets of selective anti-mosquito sterilizing agents that will not affect non-target organisms.

Computational Exposure Science: An Emerging Discipline to ...

Science.gov (United States)

Background: Computational exposure science represents a frontier of environmental science that is emerging and quickly evolving.Objectives: In this commentary, we define this burgeoning discipline, describe a framework for implementation, and review some key ongoing research elements that are advancing the science with respect to exposure to chemicals in consumer products.Discussion: The fundamental elements of computational exposure science include the development of reliable, computationally efficient predictive exposure models; the identification, acquisition, and application of data to support and evaluate these models; and generation of improved methods for extrapolating across chemicals. We describe our efforts in each of these areas and provide examples that demonstrate both progress and potential.Conclusions: Computational exposure science, linked with comparable efforts in toxicology, is ushering in a new era of risk assessment that greatly expands our ability to evaluate chemical safety and sustainability and to protect public health. The National Exposure Research Laboratory’s (NERL’s) Human Exposure and Atmospheric Sciences Division (HEASD) conducts research in support of EPA’s mission to protect human health and the environment. HEASD’s research program supports Goal 1 (Clean Air) and Goal 4 (Healthy People) of EPA’s strategic plan. More specifically, our division conducts research to characterize the movement of pollutants from the source

Discipline construction is the core element of department development, including discipline structure setting, scale, equipment, medical workers structure, clinical feature and advantage, talent training, teaching level, scientific research level, management system, and cultural construction of department. As leader and engine of discipline construction, directors' ability is an important factor for discipline construction. Clinical characteristic is the basis of discipline construction; innovation actuation is the essence of discipline construction; talents training is the guarantee of discipline construction; scientific research is the wing of discipline construction; cultural construction is the hot spring of discipline construction. Discipline construction is the theme of the development of burn surgery.

Developmental biology, the stem cell of biological disciplines.

Gilbert, Scott F

2017-12-01

Developmental biology (including embryology) is proposed as "the stem cell of biological disciplines." Genetics, cell biology, oncology, immunology, evolutionary mechanisms, neurobiology, and systems biology each has its ancestry in developmental biology. Moreover, developmental biology continues to roll on, budding off more disciplines, while retaining its own identity. While its descendant disciplines differentiate into sciences with a restricted set of paradigms, examples, and techniques, developmental biology remains vigorous, pluripotent, and relatively undifferentiated. In many disciplines, especially in evolutionary biology and oncology, the developmental perspective is being reasserted as an important research program.

To examine the relationships among four maternal variables: 1) prenatal report of discipline expectant mothers received when they were children, 2) prenatal intentions for disciplining one's own child, 3) report of intended child discipline strategies when infant is 8 months old, and 4) observed maternal role sufficiency behaviors. Replication and extension study; 3-wave prospective longitudinal design. The procedure consisted of prenatal clinic interviews in which women (N = 185) reported how their mothers handled specific child behaviors and how they intended to handle the same behaviors with their children. During a home visit when their babies were 8 months old, the mothers (n = 126) were again asked how they intended to handle these behaviors, and observations were made of maternal role sufficiency behaviors. Correlation and regression analyses were performed with data generated from an adaptation of the Ways of Handling Irritating Behavior scale, the NCAST Teaching Scale, and the HOME scale. A significant relationship was found between mothers' prenatal reports of discipline received as a child and prenatal reports of intentions for disciplining their own children. For mothers of infants, reported intentions for future child discipline strategies were predicted by their prenatal reports. Mothers with clinically at-risk scores on the NCAST Teaching Scale and HOME scale reported more intended harsh child discipline strategies than those not at-risk. Assessment for harsh, nonnurturing child discipline strategies during prenatal and well-baby health maintenance checks may assist in uncovering "red flags" for early intervention to reduce the risk of later child abuse and neglect.

The role of values in school discipline

2003-08-01

Full Text Available Despite the fact that the Constitution of South Africa uses language that could be described as “value-language”, our country is experiencing an intense moral crisis. There is an urgent need to establish ways of finding answers to the value crisis in South Africa. Morality has been and is part of education. In this article the relationship between values, education and discipline is addressed from a Biblically-based (in this case, reformational perspective. The teacher as secondary educator plays an important role in the establishment of values among learners. The Department of Education has made clear its intention to establish values in schools in its Manifesto on Values, Education and Democracy. The values emphasised in this document concur with the ideals of nation-building in the new democratic South Africa. Unfortunately, the absence of discipline and self-discipline among learners and educators implies that these ideals cannot be realised. The main cause of discipline problems can possibly be ascribed to the absence of a value system rooted in a specific life and worldview, for without such a perspective the management of discipline problems can only be symptomatic.

The Evolving Politics of Race and Social Work Activism: A Call across Borders.

Science.gov (United States)

Jeyapal, Daphne

2017-01-01

Social work has engaged with and led the revolutionary social movements of the past century. Yet today, as activism by and for racial others unfolds across the United States and Canada, our discipline remains largely silent. This article considers new ways for social workers to conceptualize social work activism, challenge the existing erasures within the profession, and construct innovative strategies to locate social work within the critical social movements of our time. Recognizing the continuity of histories of colonialism, slavery, and genocide, the author argues that social workers must engage with racialized communities' resistance through their legacy of exclusion and displacement. The author demonstrates the significance of an evolving politics of race and social justice for social work practice. © 2016 National Association of Social Workers.

Wetenschapsgeschiedenis op lange termijn: flexibiliteit en fragiliteit van disciplines

Daan Wegener

2011-03-01

Full Text Available Long-term history of science: on the flexibility and fragility of scientific disciplinesMost scientific disciplines, such as chemistry, biology and physics, are now about two centuries old. Using physics as a case study the present paper aims to account for this longevity. What kept the physics discipline together from the early nineteenth century onwards? Literature on the rise of physics suggests that the discipline was formed around energy, the ether, or other theoretical notions. Yet the twentieth-century revolutions in physics showed that the discipline could prosper without some of its most 'fundamental' concepts. Some scholars conclude that internal factors are therefore irrelevant and disciplinary identity and continuity are purely institutional. Drawing on the work of Thomas Kuhn, Peter Galison and Andrew Warwick, this paper defends a different point of view. Although there is no intellectual core of disciplines, the prolonged existence of disciplines cannot be explained without some degree of internal continuity. If there is a revolution of a theoretical level, there may still be continuity on the level of experimental practices (and vice versa. It is this flexibility that accounts for the fact that disciplines may adapt to different circumstances. In addition, an educational tradition is required to transmit knowledge from one generation to the next.

Full Text Available Pediatric dentistry provides primary and comprehensive preventive and therapeutic oral health care for infants and children through adolescence, together with special health care needs. This specialty encompasses a variety of skills, disciplines, procedures and techniques that share a common origin with other dental specialties however these have been modified and reformed to the distinctive requirements of infants, children, adolescents and special health care needs. Disciplines comprise of behavior guidance, care of the medically and developmentally compromised and disabled patient, supervision of orofacial growth and development, caries prevention, sedation, pharmacological management, and hospital dentistry including other traditional fields of dentistry. The skills apply to the ever-changing stages of dental, physical, and psychosocial development for treating conditions and diseases distinctive to growing individuals. Hence with the changing scope of practice it is imperative that the clinician stays updated with the current evidence based trends in practice, collaborates with other disciplines and Imparts quality oral health care tailored to the specific needs of every child.

Full Text Available Since 1996, the Geology (GLY program at the USF has offered “Computational Geology” as part of its commitment to prepare undergraduate majors for the quantitative aspects of their field. The course focuses on geological-mathematical problem solving. Over its twenty years, the course has evolved from a GATC (geometry-algebra-trigonometry-calculus in-discipline capstone to a quantitative literacy (QL course taught within a natural science major. With the formation of the new School of Geosciences in 2013, the merging departments re-examined their various curricular programs.

Biomimetic molecular design tools that learn, evolve, and adapt

2017-01-01

A dominant hallmark of living systems is their ability to adapt to changes in the environment by learning and evolving. Nature does this so superbly that intensive research efforts are now attempting to mimic biological processes. Initially this biomimicry involved developing synthetic methods to generate complex bioactive natural products. Recent work is attempting to understand how molecular machines operate so their principles can be copied, and learning how to employ biomimetic evolution and learning methods to solve complex problems in science, medicine and engineering. Automation, robotics, artificial intelligence, and evolutionary algorithms are now converging to generate what might broadly be called in silico-based adaptive evolution of materials. These methods are being applied to organic chemistry to systematize reactions, create synthesis robots to carry out unit operations, and to devise closed loop flow self-optimizing chemical synthesis systems. Most scientific innovations and technologies pass through the well-known “S curve”, with slow beginning, an almost exponential growth in capability, and a stable applications period. Adaptive, evolving, machine learning-based molecular design and optimization methods are approaching the period of very rapid growth and their impact is already being described as potentially disruptive. This paper describes new developments in biomimetic adaptive, evolving, learning computational molecular design methods and their potential impacts in chemistry, engineering, and medicine.

Robustness to Faults Promotes Evolvability: Insights from Evolving Digital Circuits.

Science.gov (United States)

Milano, Nicola; Nolfi, Stefano

2016-01-01

We demonstrate how the need to cope with operational faults enables evolving circuits to find more fit solutions. The analysis of the results obtained in different experimental conditions indicates that, in absence of faults, evolution tends to select circuits that are small and have low phenotypic variability and evolvability. The need to face operation faults, instead, drives evolution toward the selection of larger circuits that are truly robust with respect to genetic variations and that have a greater level of phenotypic variability and evolvability. Overall our results indicate that the need to cope with operation faults leads to the selection of circuits that have a greater probability to generate better circuits as a result of genetic variation with respect to a control condition in which circuits are not subjected to faults.

Rapidly rotating single late-type giants: New FK Comae stars?

Science.gov (United States)

Fekel, Francis C.

1986-01-01

A group of rapidly rotating single late-type giants was found from surveys of chromospherically active stars. These stars have V sin I's ranging from 6 to 46 km/sec, modest ultraviolet emission line fluxes, and strong H alpha absorption lines. Although certainly chromospherically active, their characteristics are much less extreme than those of FK Com and one or two other similar systems. One possible explanation for the newly identified systems is that they have evolved from stars similar to FK Com. The chromospheric activity and rotation of single giant stars like FK Com would be expected to decrease with time as they do in single dwarfs. Alternatively, this newly identified group may have evolved from single rapidly rotating A, or early F stars.

Physics Teaching in the Search for Its Self: From Physics as a Discipline to Physics as a Discipline-Culture

Science.gov (United States)

Tseitlin, Michael; Galili, Igal

The crisis in physics education necessitates searching for new relevant meanings of physics knowledge. This paper advocates regarding physics as the dialogue among discipline-cultures, rather than as a cluster of disciplines to be an appropriate subject of science education. In a discipline-culture one can distinguish elements of knowledge as belonging to either (1) central principles and paradigms - nucleus, (2) normal disciplinary area - body of knowledge or (3) rival knowledge of the subject - periphery. It appears that Physics cannot be represented as a simple dynamic wholeness, that is, cannot be arranged in a single tripartite (triadic) structure (this result presents a deconstruction), but incorporates several discipline-cultures. Bound together by family similarity, they maintain a conceptual discourse. Teaching physics as a culture is performed in polyphonic space of different worldviews; in other words, it is performed in a Kontrapunkt. Implications of the tripartite code are suggested with regard to representation of scientific revolutions, individual conceptual change, physics curricula and the typology of students learning science.

Violent forms of discipline in schools continue to be widespread across the globe despite their damaging effects. Since little is known about factors influencing the extent of violence applied by teachers, this study aimed to investigate the influence of teachers' stress, work satisfaction, and personal characteristics on their disciplining style. Using structural equation modeling, associations between violent discipline, burnout symptoms, and job perceptions (pressure and difficulties in class) reported by 222 teachers from 11 secondary schools in Tanzania in 2015 were analyzed. Results indicated a direct association between perceived stress and emotional violent discipline (β=.18, pjob perceptions and both forms of violent disciplining. The model showed good model fit (χ 2 [44, n=222]=67.47 (p=.013), CFI=.94, TLI=.91, IFI=.94, RMSEA=.049 [90%-CI=.02-.07, PCLOSE=.50], SRMR=.06). Our findings suggest that teachers' personal perceptions of their work as well as their stress burden play a role in their disciplining styles. Our findings underline the importance of integrating topics, such as stress and coping as well as positive, nonviolent discipline measures into the regular teacher's training and in addition to develop and evaluate school-based preventative interventions for teachers.

Pluri-Disciplinary; Against the Common Perception of Collaboration Among Disciplines

Directory of Open Access Journals (Sweden)

B. Shabani Varaki

2015-02-01

Full Text Available There are numerous kinds of definitions and discourses of conceptualization for the collaboration among disciplines. Examining a wide range of the related texts represents various, divergent and also contradictory discourses back to this up. Carefully and critically examining the common perception of collaboration among disciplines, in this paper, authors introduce an alternative so-called pluridisciplinary.rn rnAnd, it is argued that pluri-disciplinary could be considered as an umbrella term for all other modes of collaboration among disciplines including multidisciplinary, interdisciplinary, and transdiciplinary. It is also contended that unlike the conventional perception of collaborations between disciplines, epistemological and instrument rationales need to be seen as a continuous integration, so such a holistic approach will lead to a new so-called discipline; transdiciplinary. It is also articulated that there is a hierarchical relationship between disciplines in the alternative. In this paper, simple knowledge in pluridisciplinary studies will be replaced by super-complex knowledge, so called; trans-disciplinary, as a new-fashioned discipline, emerges.

Dual use research: investigation across multiple science disciplines.

Science.gov (United States)

Oltmann, Shannon

2015-04-01

Most recent studies of dual use research have focused on the life sciences, although some researchers have suggested that dual use research occurs across many disciplines. This research is an initial investigation into the prevalence of dual use research in other scientific disciplines by surveying senior editors of scientific journals, drawn from Journal Citation Reports. The survey was emailed to 7,500 journal editors with a response rate of 10.1 %. Approximately 4.8 % of life science editors reported they had to consider whether to publish dual use research and 38.9 % said they decided to not publish the research in question. In disciplines other than the life sciences, 7.2 % of editors from other science disciplines reported that they had to consider whether to publish dual use research, and 48.4 % declined to publish it. The survey investigated relationships between dual use and the journal's source of funding and place of publication, but no relationships were found. Further research is needed to better understand the occurrence of dual use research in other science disciplines.

Disciplining the children – ways of doing it, standpoints and generational relations

Directory of Open Access Journals (Sweden)

Saša Poljak

2010-01-01

Full Text Available Parents use different ways of disciplining the children in the family. The purpose of the research is to study ways, attitudes and intergenerational relations between disciplining the children in the family. One hundred and three parents appraised their ways of children disciplining, their attitudes towards the ways of disciplining, the context of experiencing, modes of implementing discipline and ways of disciplining of their mother and father when they were 10 years old. More than half of the parents describe the use of at least one of the ways of physical punishment respectively, at least one of the ways of psychical violence as a way of disciplining children in the family. Punishment ways of disciplining are connected with the experience of spousal conflict in the family, ineffectiveness, stress and the impulsive way of a response due to children disciplining. The acceptability of punishment and non-punishment ways of disciplining are positively connected with the frequency of use of this ways of disciplining. The research presented here shows a possibility that the use of a certain way of disciplining children in the family does not necessarily have a connection with a similar disciplining experience in the childhood. Corporal punishment is connected with the experience of other ways of punitive disciplining in the childhood, especially with the ways of disciplining used by mother.

Full Text Available Disciplines and studies. Innovation in the humanitiesThe classic humanities disciplines took shape in the nineteenth century in a complex, contingency- driven process in which factors such as the introduction of a ‘scientific principle’ and the securing of the humanities’ position in the universities played an important role. This process resulted in flexible disciplines that lacked rigidity. For example, there was no ambitious theorising, no development of systematic methodologies and no academic monopoly. This, in turn, made renewal in the humanities a straightforward possibility, particularly when social and cultural changes called for such renewal. The liveliness that characterises teaching and research in the humanities today testifies to this. The renewed demand for cross-disciplinary approaches has led to a number of branches of study (from holocaust and genocide studies to museum studies which explicitly present themselves as contemporary, focus on a concrete social theme, and often recall a time before the humanities disciplines had emerged in the way that they are organised and function. Anyone wishing to bring stability and continuity to this uneasy pattern of development must take account the factors that reinforced the classic disciplines back then. Among other things, a sustainable policy involves monitoring the quality of the new programmes, relaxed dealings with existing institutional structures and the provision of the necessary seed capital in the field of research.

Choe, Daniel Ewon; Olson, Sheryl L; Sameroff, Arnold J

Children who are physically disciplined are at elevated risk for externalizing problems. Conversely, maternal reasoning and reminding of rules, or inductive discipline, is associated with fewer child externalizing problems. Few studies have simultaneously examined bidirectional associations between these forms of discipline and child adjustment using cross-informant, multimethod data. We hypothesized that less inductive and more physical discipline would predict more externalizing problems, children would have evocative effects on parenting, and high levels of either form of discipline would predict low levels of the other. In a study of 241 children-spanning ages 3, 5.5, and 10-structural equation modeling indicated that 3-year-olds with higher teacher ratings of externalizing problems received higher mother ratings of physical discipline at age 5.5. Mothers endorsing more inductive discipline at child age 3 reported less physical discipline and had children with fewer externalizing problems at age 5.5. Negative bidirectional associations emerged between physical and inductive discipline from ages 5.5 to 10. Findings suggested children's externalizing problems elicited physical discipline, and maternal inductive discipline might help prevent externalizing problems and physical discipline.

All legitimate scientific disciplines are characterized by: (1) the clear definition of subjects of the study and its corresponding clear-cut name, (2) some accepted postulates, (3) set of research methods, (4) methods of quality control and processing of the obtained information, and (5) specific terminology and definitions. The inaccuracies and uncertainties in medical elementology as a new scientific discipline are discussed and some corresponding statements are made. Another and no less important problem of medical elementology is the critical unsatisfactory reproducibility of data. The complex arrangements required for the harmonization of data acquired for studies in medical elementology are offered. Main strategic aims and tactical tasks of the new scientific discipline are outlined. (author)

The impact of rapid evolution on population dynamics in the wild: experimental test of eco-evolutionary dynamics.

Science.gov (United States)

Turcotte, Martin M; Reznick, David N; Hare, J Daniel

2011-11-01

Rapid evolution challenges the assumption that evolution is too slow to impact short-term ecological dynamics. This insight motivates the study of 'Eco-Evolutionary Dynamics' or how evolution and ecological processes reciprocally interact on short time scales. We tested how rapid evolution impacts concurrent population dynamics using an aphid (Myzus persicae) and an undomesticated host (Hirschfeldia incana) in replicated wild populations. We manipulated evolvability by creating non-evolving (single clone) and potentially evolving (two-clone) aphid populations that contained genetic variation in intrinsic growth rate. We observed significant evolution in two-clone populations whether or not they were exposed to predators and competitors. Evolving populations grew up to 42% faster and attained up to 67% higher density, compared with non-evolving control populations but only in treatments exposed to competitors and predators. Increased density also correlates with relative fitness of competing clones suggesting a full eco-evolutionary dynamic cycle defined as reciprocal interactions between evolution and density. © 2011 Blackwell Publishing Ltd/CNRS.

Dealing with the challenge of building a Biochemistry Program in an integrated Medical curriculum. The need for new didactics, new focal interests, and new connections to other disciplines

Directory of Open Access Journals (Sweden)

Miguel A. R. B. Castanho

2017-07-01

Full Text Available Teaching in Health Sciences is rapidly evolving. Medical schools, for instance, are increasingly opting for integrated curricula. Biochemistry no longer is considered a discipline by itself; instead, Biochemistry is a part of a wider universe of knowledge integrated in modulus. These modulus often relate to physiological human body systems or the concept of Organic and Functional Systems. In either case, the bridging between Biochemistry, Histology, Anatomy, Physiology, and Pharmacology is largely explored. This bridging is a challenge in Biochemistry teaching. A second challenge adds to this: the way new generations of students perceive communication is much different than the way knowledge is communicated in classrooms. Modern forms of information exchange are multimedia, fast and interactive; lectures are traditionally descriptive, use classical expositive didactics and highlight detailed disciplinary matters. How to cope with the new challenges in the Biochemistry classroom will be addressed. A new biochemistry textbook, totally conceived for a Biochemistry Program in an integrated curriculum in health sciences at present will be taken as example. The choice of core contents, illustrative examples and the approach to teaching were carefully addressed in light of the new challenges identified above.

Collateral damage: rapid exposure-induced evolution of pesticide resistance leads to increased susceptibility to parasites.

Jansen, Mieke; Stoks, Robby; Coors, Anja; van Doorslaer, Wendy; de Meester, Luc

2011-09-01

Although natural populations may evolve resistance to anthropogenic stressors such as pollutants, this evolved resistance may carry costs. Using an experimental evolution approach, we exposed different Daphnia magna populations in outdoor containers to the carbamate pesticide carbaryl and control conditions, and assessed the resulting populations for both their resistance to carbaryl as well as their susceptibility to infection by the widespread bacterial microparasite Pasteuria ramosa. Our results show that carbaryl selection led to rapid evolution of carbaryl resistance with seemingly no cost when assessed in a benign environment. However, carbaryl-resistant populations were more susceptible to parasite infection than control populations. Exposure to both stressors reveals a synergistic effect on sterilization rate by P. ramosa, but this synergism did not evolve under pesticide selection. Assessing costs of rapid adaptive evolution to anthropogenic stress in a semi-natural context may be crucial to avoid too optimistic predictions for the fitness of the evolving populations. © 2011 The Author(s).

Higher rates of sex evolve in spatially heterogeneous environments.

Science.gov (United States)

Becks, Lutz; Agrawal, Aneil F

2010-11-04

The evolution and maintenance of sexual reproduction has puzzled biologists for decades. Although this field is rich in hypotheses, experimental evidence is scarce. Some important experiments have demonstrated differences in evolutionary rates between sexual and asexual populations; other experiments have documented evolutionary changes in phenomena related to genetic mixing, such as recombination and selfing. However, direct experiments of the evolution of sex within populations are extremely rare (but see ref. 12). Here we use the rotifer, Brachionus calyciflorus, which is capable of both sexual and asexual reproduction, to test recent theory predicting that there is more opportunity for sex to evolve in spatially heterogeneous environments. Replicated experimental populations of rotifers were maintained in homogeneous environments, composed of either high- or low-quality food habitats, or in heterogeneous environments that consisted of a mix of the two habitats. For populations maintained in either type of homogeneous environment, the rate of sex evolves rapidly towards zero. In contrast, higher rates of sex evolve in populations experiencing spatially heterogeneous environments. The data indicate that the higher level of sex observed under heterogeneity is not due to sex being less costly or selection against sex being less efficient; rather sex is sufficiently advantageous in heterogeneous environments to overwhelm its inherent costs. Counter to some alternative theories for the evolution of sex, there is no evidence that genetic drift plays any part in the evolution of sex in these populations.

Toxicodynetics: A new discipline in clinical toxicology.

Science.gov (United States)

Baud, F J; Houzé, P; Villa, A; Borron, S W; Carli, P

2016-05-01

Regarding the different disciplines that encompass the pharmacology and the toxicology, none is specifically dedicated to the description and analysis of the time-course of relevant toxic effects both in experimental and clinical studies. The lack of a discipline devoted to this major field in toxicology results in misconception and even in errors by clinicians. Review of the basic different disciplines that encompass pharmacology toxicology and comparing with the description of the time-course of effects in conditions in which toxicological analysis was not performed or with limited analytical evidence. Review of the literature clearly shows how misleading is the current extrapolation of toxicokinetic data to the description of the time-course of toxic effects. A new discipline entitled toxicodynetics should be developed aiming at a more systematic description of the time-course of effects in acute human and experimental poisonings. Toxicodynetics might help emergency physicians in risk assessment when facing a poisoning and contribute to a better assessment of quality control of data collected by poison control centres. Toxicodynetics would also allow a quantitative approach to the clinical effects resulting from drug-drug interaction. Copyright © 2016. Published by Elsevier Masson SAS.

Rapid evolution of pest, pathogen and wildlife populations can have undesirable effects; for example, when insects evolve resistance to pesticides or fishes evolve smaller body size in response to harvest. A destructive invasive species in the Laurentian Great Lakes, the sea lamprey (Petromyzon marinus) has been controlled with the pesticide 3-trifluoromethyl-4-nitrophenol (TFM) since the 1950s. We evaluated the likelihood of sea lamprey evolving resistance to TFM by (1) reviewing sea lamprey life history and control; (2) identifying physiological and behavioural resistance strategies; (3) estimating the strength of selection from TFM; (4) assessing the timeline for evolution; and (5) analyzing historical toxicity data for evidence of resistance. The number of sea lamprey generations exposed to TFM was within the range observed for fish populations where rapid evolution has occurred. Mortality from TFM was estimated as 82-90%, suggesting significant selective pressure. However, 57 years of toxicity data revealed no increase in lethal concentrations of TFM. Vigilance and the development of alternative controls are required to prevent this aquatic invasive species from evolving strategies to evade control.

Evaluation methods for physical activity-promoting mobile technologies: an interdisciplinary scoping review

Directory of Open Access Journals (Sweden)

Claire McCallum

2015-10-01

Full Text Available There are many thousands of mobile apps, wearables and other technologies available to support and promote physical activity. However, the rapidly evolving nature of these technologies means that the methodologies traditionally used to evaluate the effectiveness of behaviour change interventions (such as the randomised controlled trial may not be appropriate to evaluate their effectiveness. A scoping review was conducted to identify the methods currently being used to evaluate physical activity-promoting mobile technologies across health and computing science disciplines. In addition to the range of methods used, the review explored their strengths and weaknesses. The results improve understandings of when and why to use existing methods from health and computing science. Opportunities for combining and hybridising methods across the two disciplines are also identified. The review will be used to inform the development and piloting of novel, ‘fit-for-purpose’ research designs that will allow rigorous evaluation of the effectiveness of rapidly-evolving physical activity-promoting mobile technologies and their ‘active ingredients’ to build an evidence base of what works, why and for whom.

2004-03-01

In response to calls to improve the efficacy of health care services, there is an increasing focus on the processes of achieving a continuous improvement of services and practices. One specific response is that of the NHS Modernization Agency and National Health Service University in relation to the Discipline of Improvement in Health and Social Care. This paper draws on a study that explored the underpinning knowledge base of the Discipline of Improvement and focuses on describing the framework that was developed. The two-dimensional framework is composed of five primary categories, which cross-link to 11 competencies. The study concludes that the Discipline of Improvement draws together a group of ideas that together cohere to form a distinctive model to aid the improvement of health care. While some of these ideas are well-established, the way in which the Discipline of Improvement makes connections between them offers something new to our understanding of change in the complex world of health care provision, and to nursing management.

Basal metabolic rate can evolve independently of morphological and behavioural traits.

Science.gov (United States)

Mathot, K J; Martin, K; Kempenaers, B; Forstmeier, W

2013-09-01

Quantitative genetic analyses of basal metabolic rate (BMR) can inform us about the evolvability of the trait by providing estimates of heritability, and also of genetic correlations with other traits that may constrain the ability of BMR to respond to selection. Here, we studied a captive population of zebra finches (Taeniopygia guttata) in which selection lines for male courtship rate have been established. We measure BMR in these lines to see whether selection on male sexual activity would change BMR as a potentially correlated trait. We find that the genetic correlation between courtship rate and BMR is practically zero, indicating that the two traits can evolve independently of each other. Interestingly, we find that the heritability of BMR in our population (h(2)=0.45) is markedly higher than was previously reported for a captive zebra finch population from Norway. A comparison of the two studies shows that additive genetic variance in BMR has been largely depleted in the Norwegian population, especially the genetic variance in BMR that is independent of body mass. In our population, the slope of BMR increase with body mass differs not only between the sexes but also between the six selection lines, which we tentatively attribute to genetic drift and/or founder effects being strong in small populations. Our study therefore highlights two things. First, the evolvability of BMR may be less constrained by genetic correlations and lack of independent genetic variation than previously described. Second, genetic drift in small populations can rapidly lead to different evolvabilities across populations.

Disciplined Improvisation: Characteristics of Inquiry in Mindfulness-Based Teaching.

Science.gov (United States)

Crane, Rebecca S; Stanley, Steven; Rooney, Michael; Bartley, Trish; Cooper, Lucinda; Mardula, Jody

Evidence for the effectiveness of mindfulness-based stress reduction (MBSR) and mindfulness-based cognitive therapy (MBCT) is rapidly growing as interest in this field expands. By contrast, there are few empirical analyses of the pedagogy of MBSR and MBCT. Development of the evidence base concerning the teaching of MBCT or MBSR would support the integrity of the approach in the context of rapid expansion. This paper describes an applied conversation analysis (CA) of the characteristics of inquiry in the MBSR and MBCT teaching process. Audio-recordings of three 8-week MBCT and MBSR classes, with 24, 12, and 6 participants, were transcribed and systematically examined. The study focused on the teacher-led interactive inquiry which takes place in each session after a guided meditation practice. The study describes and analyzes three practices within the inquiry process that can be identified in sequences of talk: turn-taking talk involving questions and reformulations; the development of participant skills in a particular way of describing experience; and talk that constructs intersubjective connection and affiliation within the group. CA enables fine-grained analysis of the interactional work of mindfulness-based inquiry. Inquiry is a process of disciplined improvisation which is both highly specific to the conditions of the moment it took place in and uses repeated and recognizable patterns of interaction.

A rapidly evolving secretome builds and patterns a sea shell

Directory of Open Access Journals (Sweden)

Green Kathryn

2006-11-01

Full Text Available Abstract Background Instructions to fabricate mineralized structures with distinct nanoscale architectures, such as seashells and coral and vertebrate skeletons, are encoded in the genomes of a wide variety of animals. In mollusks, the mantle is responsible for the extracellular production of the shell, directing the ordered biomineralization of CaCO3 and the deposition of architectural and color patterns. The evolutionary origins of the ability to synthesize calcified structures across various metazoan taxa remain obscure, with only a small number of protein families identified from molluskan shells. The recent sequencing of a wide range of metazoan genomes coupled with the analysis of gene expression in non-model animals has allowed us to investigate the evolution and process of biomineralization in gastropod mollusks. Results Here we show that over 25% of the genes expressed in the mantle of the vetigastropod Haliotis asinina encode secreted proteins, indicating that hundreds of proteins are likely to be contributing to shell fabrication and patterning. Almost 85% of the secretome encodes novel proteins; remarkably, only 19% of these have identifiable homologues in the full genome of the patellogastropod Lottia scutum. The spatial expression profiles of mantle genes that belong to the secretome is restricted to discrete mantle zones, with each zone responsible for the fabrication of one of the structural layers of the shell. Patterned expression of a subset of genes along the length of the mantle is indicative of roles in shell ornamentation. For example, Has-sometsuke maps precisely to pigmentation patterns in the shell, providing the first case of a gene product to be involved in molluskan shell pigmentation. We also describe the expression of two novel genes involved in nacre (mother of pearl deposition. Conclusion The unexpected complexity and evolvability of this secretome and the modular design of the molluskan mantle enables

Ritualistics: a New Discipline in the History of Religions

Directory of Open Access Journals (Sweden)

Jørgen Podemann Sørensen

1993-01-01

Full Text Available The history of Religions is in need of subdisciplines. Those that it has are mostly derived from other academic disciplines such as psychology, sociology, or, to mention a more recent invention, aesthetics. Interdisciplinary studies are in many ways a characteristic, inherent feature of the humanities, and certainly not to be resented or mistrusted. It is, however, worth noticing that the History of Religions has only one discipline entirely of its own: a comparative, cross-cultural, religio-specific discipline sometimes called the phenomenology of religion. The study of ritual is more than just the study of a very broad. It is with a view to the further exploration of the way meaning and form are put to work in ritual, and the way ritual determines and conditions the form of representations, that ritualistics can be suggested as a new discipline.

Streambeds Merit Recognition as a Scientific Discipline

Science.gov (United States)

Constantz, J. E.

2016-12-01

Streambeds are generally viewed as simply sediments beneath streams, sediments topping alluvial aquifers, or sediments housing aquatic life, rather than as distinct geographic features comparable to soils and surficial geologic formations within watersheds. Streambeds should be viewed as distinct elements within watersheds, e.g., as akin to soils. In this presentation, streambeds are described as central features in watersheds, cycling water between the surface and underlying portions of the watershed. Regarding their kinship to soils, soils are often described as surficial sediments largely created by atmospheric weathering of underlying geologic parent material, and similarly, streambeds should be described as submerged sediments largely created by streamflow modification of underlying geologic parent material. Thus, streambeds are clearly overdue for recognition as their own scientific discipline along side other well-recognized disciplines within watersheds; however, slowing progress in this direction, the point is often made that hyporheic zones should be considered comparable to streambeds, but this is as misguided as equating unsaturated zones to soils. Streambeds and soils are physical geographic features of relatively constant volume, while hyporheic and unsaturated zones are hydrologic features of varying volume. Expanded upon in this presentation, 'Streambed Science' is proposed for this discipline, which will require both a well-designed protocol to physically characterize streambeds as well as development of streambed taxonomy, for suitable recognition as an independent discipline within watersheds.

Comparative Medicine: An Inclusive Crossover Discipline.

Macy, James; Horvath, Tamas L

2017-09-01

Comparative Medicine is typically defined as a discipline which relates and leverages the biological similarities and differences among animal species to better understand the mechanism of human and animal disease. It has also been defined as a field of study concentrating on similarities and differences between human and veterinary medicine and is increasingly associated with animal models of human disease, including the critical role veterinarians, animal resource centers, and Institutional Animal Care and Use Committees play in facilitating and ensuring humane and reproducible laboratory animal care and use. To this end, comparative medicine plays a pivotal role in reduction, refinement, and replacement in animals in biomedical research. On many levels, comparative medicine facilitates the translation of basic science knowledge into clinical applications; applying comparative medicine concepts throughout the translation process is critical for success. In addition to the supportive role of comparative medicine in the research enterprise, its role as a distinct and independent scientific discipline should not be lost. Although comparative medicine's research "niche" is not one particular discipline or disease process, rather, it is the investigative mindset that seeks to reveal common threads that weave different pathophysiologic processes into translatable approaches and outcomes using various models.

Discipline in early childhood.

Science.gov (United States)

Howard, B J

1991-12-01

As pediatricians we have an opportunity and a responsibility to guide parents in the structure of discipline they set up for their children. The major goals of this structure are to help children develop a sense of being both lovable and capable. To feel lovable a child needs an enduring responsive relationship that conveys positive regard. Attending to children promptly, giving individual time daily, acknowledging positive behaviors, and ignoring minor transgressions all help them feel valued. Active listening without judgment demonstrates acceptance of children's feelings. Talking to children without labels or generalizations but with specific feedback about their actions and with congruent emotional tone is respectful and promotes self-esteem. Children also deserve assistance with transitions, thanks, and apologies as appropriate. To feel (and become) capable, children need a consistent structure of routines, good models, respectful instruction, and progressive expectations so that they have an ongoing experience of success. To grow as individuals they need opportunities to make choices relevant to their interests and role-taking opportunities to gain perspective on social interaction. Praise and rewards motivate as well as instruct children, but they also need to experience consequences to their actions. Natural consequences are optimal but parents also need to design logical consequences that are graded, related, prompt, and reasonable for a child's misbehaviors. Consequences are most effective when given after only one request, exactly as clearly promised by the adult involved without interference by others. Time out is one of the most effective consequences for young children when used properly. Physical punishment has multiple negative effects on a child's development, especially if used noncontingently. Intrapersonal and family factors predispose parents to predictable problems in establishing healthy discipline. Pediatricians can play an important role in

High-frequency collocations of nouns in research articles across eight disciplines

Directory of Open Access Journals (Sweden)

Matthew Peacock

2012-04-01

Full Text Available This paper describes a corpus-based analysis of the distribution of the high-frequency collocates of abstract nouns in 320 research articles across eight disciplines: Chemistry, Computer Science, Materials Science, Neuroscience, Economics, Language and Linguistics, Management, and Psychology. Disciplinary variation was also examined – very little previous research seems to have investigated this. The corpus was analysed using WordSmith Tools. The 16 highest-frequency nouns across all eight disciplines were identified, followed by the highest-frequency collocates for each noun. Five disciplines showed over 50% variance from the overall results. Conclusions are that the differing patterns revealed are disciplinary norms and represent standard terminology within the disciplines arising from the topics discussed, research methods, and content of discussions. It is also concluded that the collocations are an important part of the meanings and functions of the nouns, and that this evidence of sharp discipline differences underlines the importance of discipline-specific collocation research.

Reclaiming the University: transforming economics as a discipline

Directory of Open Access Journals (Sweden)

Arne Heise

2018-05-01

Full Text Available Economics as a discipline is currently in disarray. In the aftermath of the global financial crisis, academic experts, students, commentators, practitioners and politicians all questioned the status of academic economics and many called for a ‘new economic thinking’. Nearly a decade later, however, there is little evidence of a transformation in research and teaching. The present study first clarifies what is meant by a transformation of economics as a discipline, since this remains an ill-defined term and may be interpreted in very different ways. It then establishes the conditions of a successful transformation of the discipline in terms of intra-disciplinary and extra-disciplinary factors. The paper argues that economics as a discipline cannot be expected to trigger this transformation by itself (i.e. via self-regulation, since the ‘market for economic ideas’ is prone to market failure. In addition, the influence of external factors and actors on the market may serve to distort the congruence between the individual researcher’s utility and societal welfare. External incentives are therefore required to establish constitutional guardrails that ensure fair competition between ideas.

Establishing relevance and effective communication are key mechanisms for building student and community engagement in a topic and can be used to promote the importance of working across disciplines to solve problems. Sustainability, including the impacts of and responses to climate change, is an inherently interdisciplinary issue and can be infused across courses and curricula in a variety of ways. Key topics such as climate change, hazards, and food, water, and energy production and sustainability are relevant to a wide audience and can be used to build student engagement. Using real-world examples, service learning, and focusing on the local environment may further boost engagement by establishing relevance between sustainability issues and students' lives. Communication plays a key role in the exchange of information across disciplines and allows for a more holistic approach to tackling the complex climate and sustainability issues our society faces. It has the power to bridge gaps, break down disciplinary silos, and build connections among diverse audiences with a wide range of expertise, including scientists, policy-makers, stakeholders, and the general public. It also aids in planning and preparation for, response to, and mitigation of issues related to sustainability, including the impacts of climate change, to lessen the detrimental effects of unavoidable events such as sea level rise and extreme weather events. Several workshops from the InTeGrate and On the Cutting Edge projects brought together educators and practitioners from a range of disciplines including geoscience, engineering, social science, and more to encourage communication and collaboration across disciplines. They supported networking, community-building, and sharing of best practices for preparing our students for a sustainable future, both in and out of the workplace, and across disciplines. Interdisciplinary teams are also working together to author curricular materials that highlight

Evolvability Is an Evolved Ability: The Coding Concept as the Arch-Unit of Natural Selection.

Science.gov (United States)

Janković, Srdja; Ćirković, Milan M

2016-03-01

Physical processes that characterize living matter are qualitatively distinct in that they involve encoding and transfer of specific types of information. Such information plays an active part in the control of events that are ultimately linked to the capacity of the system to persist and multiply. This algorithmicity of life is a key prerequisite for its Darwinian evolution, driven by natural selection acting upon stochastically arising variations of the encoded information. The concept of evolvability attempts to define the total capacity of a system to evolve new encoded traits under appropriate conditions, i.e., the accessible section of total morphological space. Since this is dependent on previously evolved regulatory networks that govern information flow in the system, evolvability itself may be regarded as an evolved ability. The way information is physically written, read and modified in living cells (the "coding concept") has not changed substantially during the whole history of the Earth's biosphere. This biosphere, be it alone or one of many, is, accordingly, itself a product of natural selection, since the overall evolvability conferred by its coding concept (nucleic acids as information carriers with the "rulebook of meanings" provided by codons, as well as all the subsystems that regulate various conditional information-reading modes) certainly played a key role in enabling this biosphere to survive up to the present, through alterations of planetary conditions, including at least five catastrophic events linked to major mass extinctions. We submit that, whatever the actual prebiotic physical and chemical processes may have been on our home planet, or may, in principle, occur at some time and place in the Universe, a particular coding concept, with its respective potential to give rise to a biosphere, or class of biospheres, of a certain evolvability, may itself be regarded as a unit (indeed the arch-unit) of natural selection.

Medical licensing board characteristics and physician discipline: an empirical analysis.

Science.gov (United States)

Law, Marc T; Hansen, Zeynep K

2010-02-01

This article investigates the relationship between the characteristics of medical licensing boards and the frequency with which boards discipline physicians. Specifically, we take advantage of variation in the structure of medical licensing boards between 1993 and 2003 to determine the effect of organizational and budgetary independence, public oversight, and resource constraints on rates of physician discipline. We find that larger licensing boards, boards with more staff, and boards that are organizationally independent from state government discipline doctors more frequently. Public oversight and political control over board budgets do not appear to influence the extent to which medical licensing boards discipline doctors. These findings are broadly consistent with theories of regulatory behavior that emphasize the importance of bureaucratic autonomy for effective regulatory enforcement.

QUEUEING DISCIPLINES BASED ON PRIORITY MATRIX

Directory of Open Access Journals (Sweden)

Taufik I. Aliev

2014-11-01

Full Text Available The paper deals with queueing disciplines for demands of general type in queueing systems with multivendor load. A priority matrix is proposed to be used for the purpose of mathematical description of such disciplines, which represents the priority type (preemptive priority, not preemptive priority or no priority between any two demands classes. Having an intuitive and simple way of priority assignment, such description gives mathematical dependencies of system operation characteristics on its parameters. Requirements for priority matrix construction are formulated and the notion of canonical priority matrix is given. It is shown that not every matrix, constructed in accordance with such requirements, is correct. The notion of incorrect priority matrix is illustrated by an example, and it is shown that such matrixes do not ensure any unambiguousness and determinacy in design of algorithm, which realizes corresponding queueing discipline. Rules governing construction of correct matrixes are given for canonical priority matrixes. Residence time for demands of different classes in system, which is the sum of waiting time and service time, is considered as one of the most important characteristics. By introducing extra event method Laplace transforms for these characteristics are obtained, and mathematical dependencies are derived on their basis for calculation of two first moments for corresponding characteristics of demands queueing

Parenting and late adolescent emotional adjustment: mediating effects of discipline and gender.

Science.gov (United States)

McKinney, Cliff; Milone, Mary Catherine; Renk, Kimberly

2011-08-01

Research suggests that parenting styles are related to the types of discipline parents utilize and that the coupling of parenting styles and discipline techniques are related to child outcomes. Although extant research examines the effects of parenting styles and discipline on child and early adolescent adjustment, less is known about adjustment in late adolescents, also described as emerging adults. Thus, the current study investigated the relationships among parenting styles (e.g., authoritative, authoritarian, permissive), discipline strategies (e.g., non-violent discipline, psychological aggression, physical assault), and emerging adult emotional adjustment (e.g., self-esteem, depression, and anxiety). The sample consisted of 526 participants ranging in age from 18 to 22 years. Results were analyzed with structural equation modeling and suggest that, although perceived parenting styles and discipline are both correlated with emerging adult emotional adjustment, perceived parenting is associated with emerging adult emotional adjustment for females but not males when examined simultaneously with perceived discipline. This finding demonstrates the importance of examining the direct and indirect relationships in the context of gender dyads.

Animals Used in Research and Education, 1966-2016: Evolving Attitudes, Policies, and Relationships.

Lairmore, Michael D; Ilkiw, Jan

2015-01-01

Since the inception of the Association of American Veterinary Medical Colleges (AAVMC), the use of animals in research and education has been a central element of the programs of member institutions. As veterinary education and research programs have evolved over the past 50 years, so too have societal views and regulatory policies. AAVMC member institutions have continually responded to these events by exchanging best practices in training their students in the framework of comparative medicine and the needs of society. Animals provide students and faculty with the tools to learn the fundamental knowledge and skills of veterinary medicine and scientific discovery. The study of animal models has contributed extensively to medicine, veterinary medicine, and basic sciences as these disciplines seek to understand life processes. Changing societal views over the past 50 years have provided active examination and continued refinement of the use of animals in veterinary medical education and research. The future use of animals to educate and train veterinarians will likely continue to evolve as technological advances are applied to experimental design and educational systems. Natural animal models of both human and animal health will undoubtedly continue to serve a significant role in the education of veterinarians and in the development of new treatments of animal and human disease. As it looks to the future, the AAVMC as an organization will need to continue to support and promote best practices in the humane care and appropriate use of animals in both education and research.

NASA's Earth Observing System (EOS) is a coordinated series of satellites for long term global observations. NASA's Earth Observing System Data and Information System (EOSDIS) is a petabyte-scale archive of environmental data that supports global climate change research by providing end-to-end services from EOS instrument data collection to science data processing to full access to EOS and other earth science data. On a daily basis, the EOSDIS ingests, processes, archives and distributes over 3 terabytes of data from NASA's Earth Science missions representing over 3500 data products ranging from various types of science disciplines. EOSDIS is currently comprised of 12 discipline specific data centers that are collocated with centers of science discipline expertise. Metadata is used in all aspects of NASA's Earth Science data lifecycle from the initial measurement gathering to the accessing of data products. Missions use metadata in their science data products when describing information such as the instrument/sensor, operational plan, and geographically region. Acting as the curator of the data products, data centers employ metadata for preservation, access and manipulation of data. EOSDIS provides a centralized metadata repository called the Earth Observing System (EOS) ClearingHouse (ECHO) for data discovery and access via a service-oriented-architecture (SOA) between data centers and science data users. ECHO receives inventory metadata from data centers who generate metadata files that complies with the ECHO Metadata Model. NASA's Earth Science Data and Information System (ESDIS) Project established a Tiger Team to study and make recommendations regarding the adoption of the international metadata standard ISO 19115 in EOSDIS. The result was a technical report recommending an evolution of NASA data systems towards a consistent application of ISO 19115 and related standards including the creation of a NASA-specific convention for core ISO 19115 elements.

Full Text Available Biochemistry is widely considered an essential background in a Nutrition Course framework. At theFaculdade de Saude Publica, USP, it is a direct requirement to eight disciplines of the syllabus and anindirect requirement to another nine disciplines. Nevertheless, a previous interview study involvingNutrition students and Nutritionists revealed a contradictory image of Biochemistry. Although stu-dents and Nutritionists admitted the important role played by Biochemistry, most of the respondentsdeclared that they could not foresee any application of Biochemical contents in their professional life.Aiming to change this situation, a deep intervention in the Biochemistry discipline was carried on.The discipline was planned in such a way that all the contents to be taught was directly derived fromsubjects or situations matching the interests of nutrition students. Instead of a classical lecture basedcourse, collaborative learning was the methodological choice, taking advantage of practical activitiesinvolving educational software and laboratory work as well. The course was carried on in 180 hoursand a variety of strategies were employed, especially small group discussion and problem solving. Thestudents were given a booklet containing all the exercises and problems, which acted as course guide.At the end of the course, an evaluation survey was carried out. It is noticeable that, according tostudents answers: 100% agreed that Biochemistry was intimately linked to Nutrition; 83% appreciatedthe didactical methodologies employed; 89% would like to continue studying Biochemistry in a furtherdiscipline; 96% declared that the discipline has raised their interest in Biochemistry. In respect tothe assessment of the students, these results are in accordance with the opinion of teachers and TAsengaged in restructuring Biochemistry courses.

Sobrino, Francisco José; de la Cuadra, Crótida; Guillén, Pedro

2015-06-01

Despite overuse injuries being previously described as the most frequent in ballet, there are no studies on professional dancers providing the specific clinical diagnoses or type of injury based on the discipline. Overuse injuries are the most frequent injuries in ballet, with differences in the type and frequency of injuries based on discipline. Cross-sectional study; Level of evidence, 3. This was a descriptive cross-sectional study performed between January 1, 2005, and October 10, 2010, on injuries occurring in professional dancers from leading Spanish dance companies who practiced disciplines such as classical, neoclassical, contemporary, and Spanish ballet. Data, including type of injury, were obtained from specialized medical services at the Trauma Service, Fremap, Madrid, Spain. A total of 486 injuries were evaluated, a significant number of which were overuse disorders (P ballet (82.60%). Injuries were more frequent among female dancers (75.90%) and classical ballet (83.60%). A statistically significant prevalence of patellofemoral pain syndrome was found in the classical discipline (P = .007). Injuries of the adductor muscles of the thigh (P = .001) and of the low back facet (P = .02) in the Spanish ballet discipline and lateral snapping hip (P = .02) in classical and Spanish ballet disciplines were significant. Overuse injuries were the most frequent injuries among the professional dancers included in this study. The prevalence of injuries was greater for the most technically demanding discipline (classical ballet) as well as for women. Patellofemoral pain syndrome was the most prevalent overuse injury, followed by Achilles tendinopathy, patellar tendinopathy, and mechanical low back pain. Specific clinical diagnoses and injury-based differences between the disciplines are a key factor in ballet.

The thermal dependency of locomotor performance evolves rapidly within an invasive species.

Kosmala, Georgia K; Brown, Gregory P; Christian, Keith A; Hudson, Cameron M; Shine, Richard

2018-05-01

Biological invasions can stimulate rapid shifts in organismal performance, via both plasticity and adaptation. We can distinguish between these two proximate mechanisms by rearing offspring from populations under identical conditions and measuring their locomotor abilities in standardized trials. We collected adult cane toads ( Rhinella marina ) from invasive populations that inhabit regions of Australia with different climatic conditions. We bred those toads and raised their offspring under common-garden conditions before testing their locomotor performance. At high (but not low) temperatures, offspring of individuals from a hotter location (northwestern Australia) outperformed offspring of conspecifics from a cooler location (northeastern Australia). This disparity indicates that, within less than 100 years, thermal performance in cane toads has adapted to the novel abiotic challenges that cane toads have encountered during their invasion of tropical Australia.

Calvin’s view on church discipline and unity: a South African perspective

Directory of Open Access Journals (Sweden)

P.J. Strauss

2010-07-01

Full Text Available The reformer John Calvin, born in 1509, considers discipline and unity as two essential aspects of the Christian church. According to him, the bond of church discipline is a way to unite church members in the truth of the Word and the Christian faith based thereupon. If discipline is exercised with exaggerated strictness and without compassion, tolerance and love, it can break the unity. Because church unity is essentially a unity of faith, or a unity in the truth of the Word, discipline can sever adulterated elements that threaten the unity from the church. Discipline, if correctly ap- plied, builds the unity of the church as a unity in religious truths.

A classical approach to the restoration of discipline in South African schools

Full Text Available As a result of the era of civil disobedience associated with the struggle for freedom and democracy discipline in many schools has deteriorated. The persistent lack of discipline in all South African schools can only be countered by means of a wise application of discipline. Application of “discipline” according to the standard dictionary meanings of the word will, however, not be appropriate since it implies a clamp-down on disruptive behaviour, including punishment, chastisement and retribution. Discipline associated with the paideia ideal of well-educatedness and of the educator as the servant of his learners (paidagogos, though within the context of a reformational perspective of discipline on the other hand, will be more suitable.

Social aspects of the learning environment, also called classroom climate, are important for students’ cognitive and affective learning outcomes. In this thesis the classroom climate is operationalised by means of two components: the teacher-class relationship and classroom discipline. The teacher-class relationship is described with the dimensions of control and affiliation, and classroom discipline is described with sensitive, directive and aggressive discipline strategies. Practical knowle...

Legal accountability for public school discipline: fact or fiction?

Directory of Open Access Journals (Sweden)

Elda de Waal

2011-01-01

Full Text Available Educators, learners and parents/caregivers should be held accountable for instilling learner discipline through clear guidelines and limitations to achieve security at public schools. Two previously identified education challenges are sustaining well-disciplined education systems and ensuring that educators are attentive to legal parameters in making decisions and dealing with discipline. This article adds a third challenge: convincing educators, learners and parents/caregivers of their accountability concerning creating/maintaining safe learning environments. Five subordinate legislation documents relevant to legal accountability are scrutinized, as well as relevant case law. The article follows a documentary comparative perspective using a secondary analysis method: appraising legal guidelines and asking questions to draw conclusions and make pragmatic action-oriented suggestions.

Páramo is the world’s fastest evolving and coolest biodiversity hotspot

Full Text Available Understanding the processes that cause speciation is a key aim of evolutionary biology. Lineages or biomes that exhibit recent and rapid diversification are ideal model systems for determining these processes. Species rich biomes reported to be of relatively recent origin, i.e., since the beginning of the Miocene, include Mediterranean ecosystems such as the California Floristic Province, oceanic islands such as the Hawaiian archipelago and the Neotropical high elevation ecosystem of the Páramos. Páramos constitute grasslands above the forest tree-line (at elevations of c. 2800–4700 m with high species endemism. Organisms that occupy this ecosystem are a likely product of unique adaptations to an extreme environment that evolved during the last three to five million years when the Andes reached an altitude that was capable of sustaining this type of vegetation. We compared net diversification rates of lineages in fast evolving biomes using 73 dated molecular phylogenies. Based on our sample, we demonstrate that average net diversification rates of Páramo plant lineages are faster than those of other reportedly fast evolving hotspots and that the faster evolving lineages are more likely to be found in Páramos than the other hotspots. Páramos therefore represent the ideal model system for studying diversification processes. Most of the speciation events that we observed in the Páramos (144 out of 177 occurred during the Pleistocene possibly due to the effects of species range contraction and expansion that may have resulted from the well-documented climatic changes during that period. Understanding these effects will assist with efforts to determine how future climatic changes will impact plant populations.

Stimulating Creativity by Integrating Research and Teaching Across the Academic Disciplines

Science.gov (United States)

Taylor, Richard

2013-03-01

Creativity is a human adventure fueled by the process of exploration. But how do we explore our intellectual interests? In this talk, I'll propose that we seek out our creative opportunities using an inherent natural process. This process might, therefore, exploit search strategies found across diverse natural systems - ranging from the way animals forage for food to the way the human eye locates information embedded within complex patterns. The symbolic significance of this hypothesis lies in its call for educational institutes to provide environments that encourage our natural explorations rather those that stamp restrictive, artificial `order' on the process. To make my case, I'll review some of my own research trajectories followed during my RCSA Cottrell Scholarship at the University of Oregon (UO). My first conclusion will be that it is fundamentally unnatural to declare divides across disciplines. In particular, the infamous `art-science divide' is not a consequence of our natural creative searches but instead arises from our practical inability to accommodate the rapid drive toward academic specialization. Secondly, divides between research and teaching activities are equally unnatural - both endeavors are driven by the same creative strategy and are intertwined within the same natural process. This applies equally to the experiences of professors and students. I will end with specific success stories at the UO. These include a NSF IGERT project (focused on accelerating students' transitions from classroom to research experiences) and a collaboration between architects and professors to design a building (the recently opened Lewis Integrative Science Building) that encourages daily encounters between students and professors across research disciplines.

The development’s phases of educational sciences as academic disciplin in Hungary in first half of the 20th century

Directory of Open Access Journals (Sweden)

András Németh

2017-01-01

Full Text Available A number of historical anthologies and monographs have been published recently that give priority to the social approach in the history of science of the educational sciences – using Stichweh’s concept of discipline – as discipline formation and discipline development. The study to date indicates that four phases in the academic discipline development of the educational sciences in Hungary can be distinguished. In the first phase we find the institutional formation of pedagogy, as it was then understood, as a disciplinary field. This development proceeded most rapidly in the last third of the nineteenth century. It took on two overlapping forms, following the general institutionalization of teacher education. On the one hand, broad-based theory formation regarding educational practice took place, reaching its peak in Herbartianism. On the other hand, university courses were introduced and academic chairs created, often closely tied to philosophy, that were dedicated to pedagogy and represented the academic foundations of the discipline. The second phase, which is the focus of the present contribution continued into the twentieth century. In this period an educational movement arose that centered on the empirical paradigms of research in the social sciences. But the various lines of the movement (reform pedagogy, experimental pedagogy, child study did not always succeed at becoming established at the universities. The third phase is the phase of lasting institutionalization of the educational sciences, which in most places began already in the first half of the twentieth century. Here the German «Geisteswissenschaft» played a role. After the 2nd World War was Hungary included in the sphere of influence of the Soviet Union and began the fourth phase of development of the educational sciences in Hungary. Educational science was most highly affected among social sciences by the political power shifts oft the Stalinism.

Op het raakvlak van historische disciplines

Full Text Available At the Meeting Point of Historical DisciplinesThis contribution introduces the way in which the interaction between history and archaeology is examined, taking the case of the identification of a tomb and remains of Count William II of Holland, King of the Holy Roman Empire (†1256, in the former abbey church of Middelburg. It stresses the necessity of strict source criticism, which should be self-evident, but is at risk of receiving less attention. This is even truer when one of the disciplines is used as an auxiliary argument to support the other instead of a balanced approach. Wishful interpretation in such a case is a clear risk. The contribution gives some examples, before sketching the advance made thanks to the reapprochement of history and archaeology, and the consequent need for a registration system of archaeological data that can facilitate multi-disciplinary analysis. It ends with an introduction to the different stands in the dossier.Deze bijdrage biedt een inleiding op de wijze waarop de interactie tussen geschiedenis en archeologie wordt bekeken aan de hand van een casus betreffende het graf en de overblijfselen van de in 1256 gesneuvelde graaf Willem II van Holland, koning van het Heilige Roomse Rijk, in de voormalige abdijkerk van Middelburg. Hij benadrukt de noodzaak van een nauwgezette bronnenkritiek. Hoewel deze als vanzelfsprekend moet worden beschouwd, is er een zeker risico van verminderde zorgvuldigheid. Dit speelt vooral wanneer één van de disciplines wordt gebruikt als een hulp-argument, dat de uitkomsten van de andere moet ondersteunen, in plaats van een benadering waarbij beide disciplines in evenwicht zijn. Bij een onbalans is het risico van interpreteren in het licht van de gewenste uitkomst duidelijk aanwezig. De bijdrage geeft hiervan enkele voorbeelden, alvorens de vooruitgang te schetsen die is geboekt juist dankzij de toenadering tussen geschiedenis en archeologie, en aan te geven dat er behoefte is aan een

Full Text Available The government has three legal instruments to improve the budgetary discipline. There are internal control, good governance and accounting information. The purpose of this study is to investigate the impact of the three instruments on the budget discipline contained on research questions. First, how much impact internal control on budgetary discipline. Second, how much impact the good governance on budgetary discipline. Third, how much impact the quality of accounting information on budgetary discipline. This study was conducted at the State Ministry with a population of 34 units of analysis in 2015. The ministry was taken as a study unit because it is related to some phenomenon of violations on budgetary discipline that has occurred. Study approach using quantitative method and data analysis with partial least square. Primary data is taken with media questionnaires and secondary data taken from the respective publications of the Ministries. The results show that the impact of internal control and good governance on budget discipline is positive but weak. Then the impact of the quality of accounting information on budget discipline is negative but weak. This study was conducted when the state budget was deficit. Probable different results when study is undertaken at a time when the state budget is surplus. It is expected that the further study with the state budget on surplus and time series data to compare the results of study for making decision.

Parents' perceptions of child abuse and child discipline in Bangkok, Thailand.

Auemaneekul, Naruemon

2013-12-01

Violation of a child's right to protection is an issue for children all over the world. In Thailand, the greatest barrier to intervening in child abuse issues is the lack of awareness and the positive attitudes and beliefs on using violence as a way to discipline children. The incongruent definition used amongst Thai society and relevant sectors, causes incidences to be under reported and an obstacle to child survival and development. The present study is a qualitative study and aims to explore the perceptions of child abuse and child discipline definitions amongst parents in the Bangkok Metropolitan Area in order to extend broader knowledge for interpretation, definitions and to differentiate the line between child abuse and child discipline. Focus group discussions were used as the primary data collection method and content analysis was applied as the data analysis. The results produced two categories of parents' perceptions regarding child abuse and discipline. First, was the perception of the causes of child punishment and child discipline, and second was the meaning and difference between child abuse and child discipline. The study results would be beneficial for policy makers, health and related sectors to understand the meaning of the terms used amongst family members in order to apply and promote child protection strategies in culturally appropriate

Common and distinctive approaches to motivation in different disciplines.

Science.gov (United States)

Strombach, T; Strang, S; Park, S Q; Kenning, P

2016-01-01

Over the last couple of decades, a body of theories has emerged that explains when and why people are motivated to act. Multiple disciplines have investigated the origins and consequences of motivated behavior, and have done so largely in parallel. Only recently have different disciplines, like psychology and economics, begun to consolidate their knowledge, attempting to integrate findings. The following chapter presents and discusses the most prominent approaches to motivation in the disciplines of biology, psychology, and economics. Particularly, we describe the specific role of incentives, both monetary and alternative, in various motivational theories. Though monetary incentives are pivotal in traditional economic theory, biological and psychological theories ascribe less significance to monetary incentives and suggest alternative drivers for motivation. © 2016 Elsevier B.V.

We consider a game in which a large number of identical agents choose when to queue up at a single server after it opens. Agents are impatient for service and also incur a cost proportional to time spent in the queue. We show that the first-in–first-out queue discipline and the last......-in–first-out queue discipline both lead to a unique equilibrium arrival distribution. However, among all work-conserving queue disciplines, the first-in–first-out performs the worst in terms of equilibrium utility and welfare, while the last-in–first-out performs the best....

Vulnerable discipline: experiences of male competitive bodybuilders.

Bjørnestad, Jone; Kandal, Øyvind; Anderssen, Norman

2014-09-01

The aim was to understand experiences of male competitive bodybuilders from a non-pathologizing perspective. Six male Norwegian competitive bodybuilders were interviewed. The interviews were analysed using a meaning condensation procedure resulting in five themes: being proud of capacity for discipline, seeing a perfectionist attitude as a necessary evil, experiencing recognition within the bodybuilding community, being stigmatized outside the bodybuilding community and going on stage to display a capacity for willpower and discipline. We suggest that bodybuilders may be stigmatized for breaking social norms: by their distinctive appearance, by the way they handle suspected drug use and by challenging gender norms. © The Author(s) 2013.

The Study of Law as an Academic Discipline

Directory of Open Access Journals (Sweden)

René Brouwer

2017-12-01

Full Text Available This paper deals with the study of law as an academic discipline, in two ways. First, the study of law within the university does not speak for itself: in contrast with classical Athens, where law was not at all considered to be a matter for specialists, or Norman England, where specialists with a vocational training came to deal with the ‘common law’, in continental Europe at the end of the 11th century the study of law developed into one of the core academic disciplines at the newly established universities, as a result of the revival of the Byzantine version of Roman law as the ius commune. Second, as an academic study, contrary to what is sometimes suggested, the methods available to its students are diverse. This paper shows that law can be studied with the help of methods comparable to the ones used in other academic disciplines, notably the natural sciences and the humanities.

Violent parenting behavior, whether physical or psychological, give harms to child well-being. This study was conducted to describe and compare the prevalence of discipline methods used by mothers of 2- to 5-year-old children in Malatya, Turkey. This is a cross sectional study and 552 mothers were administered a face-to-face questionnaire describe the methods they use to discipline their children in the year previous the survey. It was observed that nine of 10 women used violence on their children physically and psychologically. The study showed that nine of 10 mothers used physical and/or psychological punishment toward their children in the previous year. Nonviolent discipline was less prevalent than punitive discipline, such as psychological and physical punishment. The most commonly used method was psychological punishment. Significant sociodemographic associations with discipline methods were found. Mother's educational level, family income, child gender, and child age were the independent predictors that explained discipline methods used by mothers. Starting parenting classes and strengthening the child protection systems at national level were suggested.

Evolving technologies drive the new roles of Biomedical Engineering.

Frisch, P H; St Germain, J; Lui, W

2008-01-01

Rapidly changing technology coupled with the financial impact of organized health care, has required hospital Biomedical Engineering organizations to augment their traditional operational and business models to increase their role in developing enhanced clinical applications utilizing new and evolving technologies. The deployment of these technology based applications has required Biomedical Engineering organizations to re-organize to optimize the manner in which they provide and manage services. Memorial Sloan-Kettering Cancer Center has implemented a strategy to explore evolving technologies integrating them into enhanced clinical applications while optimally utilizing the expertise of the traditional Biomedical Engineering component (Clinical Engineering) to provide expanded support in technology / equipment management, device repair, preventive maintenance and integration with legacy clinical systems. Specifically, Biomedical Engineering is an integral component of the Medical Physics Department which provides comprehensive and integrated support to the Center in advanced physical, technical and engineering technology. This organizational structure emphasizes the integration and collaboration between a spectrum of technical expertise for clinical support and equipment management roles. The high cost of clinical equipment purchases coupled with the increasing cost of service has driven equipment management responsibilities to include significant business and financial aspects to provide a cost effective service model. This case study details the dynamics of these expanded roles, future initiatives and benefits for Biomedical Engineering and Memorial Sloan Kettering Cancer Center.

Self-discipline outdoes IQ in predicting academic performance of adolescents.

Science.gov (United States)

Duckworth, Angela L; Seligman, Martin E P

2005-12-01

In a longitudinal study of 140 eighth-grade students, self-discipline measured by self-report, parent report, teacher report, and monetary choice questionnaires in the fall predicted final grades, school attendance, standardized achievement-test scores, and selection into a competitive high school program the following spring. In a replication with 164 eighth graders, a behavioral delay-of-gratification task, a questionnaire on study habits, and a group-administered IQ test were added. Self-discipline measured in the fall accounted for more than twice as much variance as IQ in final grades, high school selection, school attendance, hours spent doing homework, hours spent watching television (inversely), and the time of day students began their homework. The effect of self-discipline on final grades held even when controlling for first-marking-period grades, achievement-test scores, and measured IQ. These findings suggest a major reason for students falling short of their intellectual potential: their failure to exercise self-discipline.

Museology: an academic discipline or form of cultural activity?

Directory of Open Access Journals (Sweden)

Elena Ploşniţa

2013-12-01

Full Text Available Museology is the science of museums. Most experts characterize it as an independent applied scientific discipline, which studies how museums develop and optimize their activities to meet the needs of society. The term "museology" was first mentioned in the work by P.L. Martin "Praxix der Naturgeschichte" published in 1869 in Germany. But the determination of the status of museology as a science was first given by J. G. Th. Von Graesse in the article "Museology as a Science" published in the magazine „Zeitschrift für Museologie und Antiquitätenkunde" in 1883. The author announced a new scientific discipline of museology and tried to highlight its research potential. Thus, museology as a science began in 1883. Since 1960s museology is introduced as a scientific discipline in many universities around the world; there were created first centers of museological research, published numerous papers on museums. However, so far, some experts deny the scientific character of museology considering it "a discipline that coordinates a specialized type of cultural activity". In his article, the author analyzes the path of museology in the process of its development as a scientific discipline, identifies the problems of its classification in the system of sciences, and highlights the contributions of some researchers (P. van Mensch, J. Neustupny, T. Šola, Z. Stransky, R. Florescu, etc. to the consolidation of its status of an independent science. In conclusion, the author believes that museology is an academic science, but a relatively young and developing.

A neighbourhood evolving network model

Many social, technological, biological and economical systems are best described by evolved network models. In this short Letter, we propose and study a new evolving network model. The model is based on the new concept of neighbourhood connectivity, which exists in many physical complex networks. The statistical properties and dynamics of the proposed model is analytically studied and compared with those of Barabasi-Albert scale-free model. Numerical simulations indicate that this network model yields a transition between power-law and exponential scaling, while the Barabasi-Albert scale-free model is only one of its special (limiting) cases. Particularly, this model can be used to enhance the evolving mechanism of complex networks in the real world, such as some social networks development

Discipline construction is an important aspect of hospital modernization management and construction. The level of medical treatment, education, and scientific research could be assured and improved through discipline construction, which could speed up the talent training, promote science and technology innovation, and realize the sustainable development of hospital. At present, most of the hospital management models adopt the two ranks of the hospital and department. The manager of a department must grasp medical treatment, education, scientific research, and discipline construction steadily.

Research in an emerging 'big science' discipline. The case of neutron scattering in Spain

International Nuclear Information System (INIS)

Borja Gonzalez-Albo; Maria Bordons; Pedro Gorria

2010-01-01

Neutron scattering (NS) is a 'big science' discipline whose research spans over a wide spectrum of fields, from fundamental or basic science to technological applications. The objective of this paper is to track the evolution of Spanish research in NS from a bibliometric perspective and to place it in the international context. Scientific publications of Spanish authors included in the Web of Science (WoS 1970-2006) are analysed with respect to five relevant dimensions: volume of research output, impact, disciplinary diversity, structural field features and internationalisation. NS emerges as a highly internationalised fast-growing field whose research is firmly rooted in Physics, Chemistry and Engineering, but with applications in a wide range of fields. International collaboration links -present in around 70% of the documents- and national links have largely contributed to mould the existing structure of research in the area, which evolves around major neutron scattering facilities abroad. The construction of a new European neutron source (ESS) would contribute to the consolidation of the field within the EU, since it will strengthen research and improve current activity. (author)

On the Critical Role of Divergent Selection in Evolvability

Directory of Open Access Journals (Sweden)

Joel Lehman

2016-08-01

Full Text Available An ambitious goal in evolutionary robotics is to evolve increasingly complex robotic behaviors with minimal human design effort. Reaching this goal requires evolutionary algorithms that can unlock from genetic encodings their latent potential for evolvability. One issue clouding this goal is conceptual confusion about evolvability, which often obscures the aspects of evolvability that are important or desirable. The danger from such confusion is that it may establish unrealistic goals for evolvability that prove unproductive in practice. An important issue separate from conceptual confusion is the common misalignment between selection and evolvability in evolutionary robotics. While more expressive encodings can represent higher-level adaptations (e.g. sexual reproduction or developmental systems that increase long-term evolutionary potential (i.e. evolvability, realizing such potential requires gradients of fitness and evolvability to align. In other words, selection is often a critical factor limiting increasing evolvability. Thus, drawing from a series of recent papers, this article seeks to both (1 clarify and focus the ways in which the term evolvability is used within artificial evolution, and (2 argue for the importance of one type of selection, i.e. divergent selection, for enabling evolvability. The main argument is that there is a fundamental connection between divergent selection and evolvability (on both the individual and population level that does not hold for typical goal-oriented selection. The conclusion is that selection pressure plays a critical role in realizing the potential for evolvability, and that divergent selection in particular provides a principled mechanism for encouraging evolvability in artificial evolution.

Evolved H II regions

International Nuclear Information System (INIS)

Churchwell, E.

1975-01-01

A probable evolutionary sequence of H II regions based on six distinct types of observed objects is suggested. Two examples which may deviate from this idealized sequence, are discussed. Even though a size-mean density relation of H II regions can be used as a rough indication of whether a nebula is very young or evolved, it is argued that such a relation is not likely to be useful for the quantitative assignment of ages to H II regions. Evolved H II regions appear to fit into one of four structural types: rings, core-halos, smooth structures, and irregular or filamentary structures. Examples of each type are given with their derived physical parameters. The energy balance in these nebulae is considered. The mass of ionized gas in evolved H II regions is in general too large to trace the nebula back to single compact H II regions. Finally, the morphological type of the Galaxy is considered from its H II region content. 2 tables, 2 figs., 29 refs

Ethics and Reverence for the Discipline of Nursing.

Milton, Constance L

2017-01-01

Healthcare disciplines, including nursing, are emerging sciences that contain discipline-specific theories that guide the activities of research, practice, and education. The term nursing science calls forth meaning that has long been accepted and referred to as the extant nursing theories undergirded with philosophy of science. Recent writings dispute the purposes and future usage of nursing theoretical frameworks in the science of nursing. The author of this article proposes new thinking about the importance of reverence and ethical implications for the future of formal inquiry in nursing science.

[Long-term history of science: on the flexibility and fragility of scientific disciplines].

Science.gov (United States)

Wegener, Daan

2011-01-01

Most scientific disciplines, such as chemistry, biology and physics, are now about two centuries old. Using physics as a case study the present paper aims to account for this longevity. What kept the physics discipline together from the early nineteenth century onwards? Literature on the rise of physics suggests that the discipline was formed around energy, the ether, or other theoretical notions. Yet the twentieth-century revolutions in physics showed that the discipline could prosper without some of its most 'fundamental' concepts. Some scholars conclude that internal factors are therefore irrelevant and disciplinary identity and continuity are purely institutional. Drawing on the work of Thomas Kuhn, Peter Galison and Andrew Warwick, this paper defends a different point of view. Although there is no intellectual core of disciplines, the prolonged existence of disciplines cannot be explained without some degree of internal continuity. If there is a revolution of a theoretical level, there may still be continuity on the level of experimental practices (and vice versa). It is this flexibility that accounts for the fact that disciplines may adapt to different circumstances. In addition, an educational tradition is required to transmit knowledge from one generation to the next.

Maternal Acceptance: Its Contribution to Children's Favorable Perceptions of Discipline and Moral Identity.

Science.gov (United States)

Patrick, Renee B; Gibbs, John C

2016-01-01

The authors examined the contribution of maternal acceptance or warmth to children's and adolescents' perceptions of discipline and formation of moral identity. The sample consisted of 93 male and female students from Grades 5, 8, and 10 and their mothers. Students completed measures pertaining to perceived maternal discipline practices and acceptance-rejection, as well as moral identity. A subsample of mothers reported on their accepting or rejecting actions toward their children. Children were more likely to feel accepted, if their mothers used inductive discipline (vs. power assertion and love withdrawal). Perceived acceptance was also related to more favorable discipline evaluations in certain respects. Specifically, inductive discipline recipients who felt accepted also evaluated induction as appropriate and responded to it with positive and guilt-related emotions. Power assertion was evaluated as appropriate among those children who did feel accepted. Finally, among inductive discipline recipients, those who felt accepted also reported higher moral identity.

Rapid prototyping for biomedical engineering: current capabilities and challenges.

Science.gov (United States)

Lantada, Andrés Díaz; Morgado, Pilar Lafont

2012-01-01

A new set of manufacturing technologies has emerged in the past decades to address market requirements in a customized way and to provide support for research tasks that require prototypes. These new techniques and technologies are usually referred to as rapid prototyping and manufacturing technologies, and they allow prototypes to be produced in a wide range of materials with remarkable precision in a couple of hours. Although they have been rapidly incorporated into product development methodologies, they are still under development, and their applications in bioengineering are continuously evolving. Rapid prototyping and manufacturing technologies can be of assistance in every stage of the development process of novel biodevices, to address various problems that can arise in the devices' interactions with biological systems and the fact that the design decisions must be tested carefully. This review focuses on the main fields of application for rapid prototyping in biomedical engineering and health sciences, as well as on the most remarkable challenges and research trends.

We have previously used targeted active-site saturation mutagenesis to identify a number of transketolase single mutants that improved activity towards either glycolaldehyde (GA), or the non-natural substrate propionaldehyde (PA). Here, all attempts to recombine the singles into double mutants led to unexpected losses of specific activity towards both substrates. A typical trade-off occurred between soluble expression levels and specific activity for all single mutants, but many double mutants decreased both properties more severely suggesting a critical loss of protein stability or native folding. Statistical coupling analysis (SCA) of a large multiple sequence alignment revealed a network of nine co-evolved residues that affected all but one double mutant. Such networks maintain important functional properties such as activity, specificity, folding, stability, and solubility and may be rapidly disrupted by introducing one or more non-naturally occurring mutations. To identify variants of this network that would accept and improve upon our best D469 mutants for activity towards PA, we created a library of random single, double and triple mutants across seven of the co-evolved residues, combining our D469 variants with only naturally occurring mutations at the remaining sites. A triple mutant cluster at D469, E498 and R520 was found to behave synergistically for the specific activity towards PA. Protein expression was severely reduced by E498D and improved by R520Q, yet variants containing both mutations led to improved specific activity and enzyme expression, but with loss of solubility and the formation of inclusion bodies. D469S and R520Q combined synergistically to improve k(cat) 20-fold for PA, more than for any previous transketolase mutant. R520Q also doubled the specific activity of the previously identified D469T to create our most active transketolase mutant to date. Our results show that recombining active-site mutants obtained by saturation mutagenesis

Full Text Available Islamic economics is currently moving from a mere discourse on economics in Islamic perspective towards becoming a distinct science of Islamic economics. There is a systematic effort from Islamic economic scientific community to develop a discipline of Islamic economics marked by a complete body of knowledge, clear subject matter, methodology/methodologies to appraise theories and continuous growth and accumulation of knowledge. This could be done if the scientific community put strong effort in explicating all the necessary foundations of science and achieve consensus on certain important aspect of discipline. In this paper we attempt to historically survey the development of Islamic economics towards becoming a distinct discipline, evaluate the current practices a adopted by the Islamic economics’ scientific community in settling up problems, and outlining forward agenda in order to achieve this discipline status.

Full Text Available This study used bibliometric methods to analyze subject disciplines of knowledge originality and knowledge generality for Library and Information Science (LIS by using citing and cited documents from 1997 to 2006. We found that the major subject disciplines of knowledge originality and generality are still LIS, and computer science and LIS interact and influence each other closely. It is evident that number of subject disciplines of knowledge originality is higher than that of knowledge generality. The interdisciplinary characteristics of LIS are illustrated by variety areas of knowledge originality and knowledge generality. Because the number of received subject disciplines is higher than that of given subject disciplines, it suggests that LIS is an application-oriented research area. [Article content in Chinese

Targeted disruption in mice of a neural stem cell-maintaining, KRAB-Zn finger-encoding gene that has rapidly evolved in the human lineage.

Full Text Available Understanding the genetic basis of the physical and behavioral traits that separate humans from other primates is a challenging but intriguing topic. The adaptive functions of the expansion and/or reduction in human brain size have long been explored. From a brain transcriptome project we have identified a KRAB-Zn finger protein-encoding gene (M003-A06 that has rapidly evolved since the human-chimpanzee separation. Quantitative RT-PCR analysis of different human tissues indicates that M003-A06 expression is enriched in the human fetal brain in addition to the fetal heart. Furthermore, analysis with use of immunofluorescence staining, neurosphere culturing and Western blotting indicates that the mouse ortholog of M003-A06, Zfp568, is expressed mainly in the embryonic stem (ES cells and fetal as well as adult neural stem cells (NSCs. Conditional gene knockout experiments in mice demonstrates that Zfp568 is both an NSC maintaining- and a brain size-regulating gene. Significantly, molecular genetic analyses show that human M003-A06 consists of 2 equilibrated allelic types, H and C, one of which (H is human-specific. Combined contemporary genotyping and database mining have revealed interesting genetic associations between the different genotypes of M003-A06 and the human head sizes. We propose that M003-A06 is likely one of the genes contributing to the uniqueness of the human brain in comparison to other higher primates.

Full Text Available This article contains elucidation about punctuality issues and discipline in educational perspective. From the discussion that has been done it can be said that punctuality problems and discipline are very important and vital in building good and advanced of human life, because it is related to the basic, function and purpose of education as well as the teachings of Islam. Punctuality and discipline are a fundamental goal of the educational efforts and Islamic Shari'ah. In Islam, there are many concepts related to punctuality and discipline. They are obedience, self-control and behavior, submission and obedience, as well as support for the values and rules of the understanding, comprehension, awareness and responsibility. Being punctuality and discipline have to be owned and improved in education and life, and in turn, the family, society and the environment should support it in order to achieve the progress. Copyright © 2014 by Al-Ta'lim All right reserved

Separate disciplines: The study of behavior and the study of the psyche

Science.gov (United States)

Fraley, Lawrence E.; Vargas, Ernest A.

1986-01-01

The study of behavior differs fundamentally from the study of the psyche and logically cannot share the same discipline. However, while disciplines might be defined through technical exercises, they function through exercises of political power. The evolution of a discipline, though based on field and laboratory data interpreted within a specific paradigm and justified publicity by its utility to solve personal and social problems, follows a course of development in the political arenas of the academies and the professions. We happen to have a discipline, roughly connoted by the label “behavior analysis,” without an academic home (the present ones haphazardly tolerate our activities), without a professional organization (the present one lobbies only “for behavior analysis”), and without a true professional name (the present one implies an approach not a discipline). No scientific community lasts long without a supporting professional infrastructure. In explicitly asserting ourselves as a discipline, we confront a number of difficult issues such as continuing to work in departments antithetical to behaviorism and a number of problems such as what we call ourselves to identify our professional and scientific concerns. (For example, we need a term descriptive of our science in its broad sense. That term is not psychology. Too many people persist in maintaining its commitment to cognitivism. On whatever term we agree, “behavior” should constitute its stem, for our efforts focus there, not in the putative underlying psyche or its current cognitive update.) The focus of our concerns and the solutions of our problems rest on one issue: Will our discipline prosper most as a branch of psychology or as an independent discipline? Slowly, but surely, our actions demonstrate that the latter is the preferred option, but these actions, though fortuitous, occur almost by accident. By specifically programming to achieve an independent professional status we increase the

Is Primatology an equal-opportunity discipline?

Directory of Open Access Journals (Sweden)

Elsa Addessi

Full Text Available The proportion of women occupying academic positions in biological sciences has increased in the past few decades, but women are still under-represented in senior academic ranks compared to their male colleagues. Primatology has been often singled out as a model of "equal-opportunity" discipline because of the common perception that women are more represented in Primatology than in similar fields. But is this indeed true? Here we show that, although in the past 15 years the proportion of female primatologists increased from the 38% of the early 1990s to the 57% of 2008, Primatology is far from being an "equal-opportunity" discipline, and suffers the phenomenon of "glass ceiling" as all the other scientific disciplines examined so far. In fact, even if Primatology does attract more female students than males, at the full professor level male members significantly outnumber females. Moreover, regardless of position, IPS male members publish significantly more than their female colleagues. Furthermore, when analyzing gender difference in scientific productivity in relation to the name order in the publications, it emerged that the scientific achievements of female primatologists (in terms of number and type of publications do not always match their professional achievements (in terms of academic position. However, the gender difference in the IPS members' number of publications does not correspond to a similar difference in their scientific impact (as measured by their H index, which may indicate that female primatologists' fewer articles are of higher impact than those of their male colleagues.

Using ESB and BPEL for Evolving Healthcare Systems Towards Pervasive, Grid-Enabled SOA

Science.gov (United States)

Koufi, V.; Malamateniou, F.; Papakonstantinou, D.; Vassilacopoulos, G.

Healthcare organizations often face the challenge of integrating diverse and geographically disparate information technology systems to respond to changing requirements and to exploit the capabilities of modern technologies. Hence, systems evolution, through modification and extension of the existing information technology infrastructure, becomes a necessity. Moreover, the availability of these systems at the point of care when needed is a vital issue for the quality of healthcare provided to patients. This chapter takes a process perspective of healthcare delivery within and across organizational boundaries and presents a disciplined approach for evolving healthcare systems towards a pervasive, grid-enabled service-oriented architecture using the enterprise system bus middleware technology for resolving integration issues, the business process execution language for supporting collaboration requirements and grid middleware technology for both addressing common SOA scalability requirements and complementing existing system functionality. In such an environment, appropriate security mechanisms must ensure authorized access to integrated healthcare services and data. To this end, a security framework addressing security aspects such as authorization and access control is also presented.

In this review article, we examined the prevalence and characteristics of 294 mixed-methods studies in the discipline of nursing. Creswell and Plano Clark's typology was most frequently used along with concurrent timing. Bivariate statistics was most often the highest level of statistics reported in the results. As for qualitative data analysis, content analysis was most frequently used. The majority of nurse researchers did not specifically address the purpose, paradigm, typology, priority, timing, interaction, or integration of their mixed-methods studies. Strategies are suggested for improving the design, conduct, and reporting of mixed-methods studies in the discipline of nursing.

This paper tests the effect of systemic risk on deposit market discipline by interacting proxies for systemic risk with bank-specific default-risk variables. Discipline is measured by estimating a supply of deposit funds function at Thai banks from 1992 to 1997. The results show that supply decreases as bank-specific risk increases. Also, the sensitivity of funds to changes in bank-specific risk increases as systemic risk rises. Additionally, depositors decrease their sensitivity to deposit r...

Physical discipline in Chinese American immigrant families: An adaptive culture perspective.

Science.gov (United States)

Lau, Anna S

2010-07-01

Research on ethnic minority parenting has examined heritage cultural influences and contextual stressors on parenting processes. However, rarely are adaptive cultural processes considered, whereby ethnic minority parents bring their cultural values to bear in adapting to contextual demands in the host society. A survey of 107 Chinese American immigrant parents examined whether use of physical discipline can be predicted by cultural values, contextual stressors, and their interactions. Results indicated that distinct domains of cultural values were related to physical discipline in disparate ways, with some values decreasing risk and others indirectly increasing risk. There was some evidence that cultural values interacted with contextual stress to predict physical discipline. Parent-child acculturation conflicts were only related to physical discipline when parents held strong values about the importance of firm parental control. The findings illustrate how heritage cultural influences and current ecological demands may converge to shape parenting in immigrant families.

Duplicate Abalone Egg Coat Proteins Bind Sperm Lysin Similarly, but Evolve Oppositely, Consistent with Molecular Mimicry at Fertilization

Sperm and egg proteins constitute a remarkable paradigm in evolutionary biology: despite their fundamental role in mediating fertilization (suggesting stasis), some of these molecules are among the most rapidly evolving ones known, and their divergence can lead to reproductive isolation. Because of strong selection to maintain function among interbreeding individuals, interacting fertilization proteins should also exhibit a strong signal of correlated divergence among closely related species. We use evidence of such molecular co-evolution to target biochemical studies of fertilization in North Pacific abalone (Haliotis spp.), a model system of reproductive protein evolution. We test the evolutionary rates (d N/d S) of abalone sperm lysin and two duplicated egg coat proteins (VERL and VEZP14), and find a signal of co-evolution specific to ZP-N, a putative sperm binding motif previously identified by homology modeling. Positively selected residues in VERL and VEZP14 occur on the same face of the structural model, suggesting a common mode of interaction with sperm lysin. We test this computational prediction biochemically, confirming that the ZP-N motif is sufficient to bind lysin and that the affinities of VERL and VEZP14 are comparable. However, we also find that on phylogenetic lineages where lysin and VERL evolve rapidly, VEZP14 evolves slowly, and vice versa. We describe a model of sexual conflict that can recreate this pattern of anti-correlated evolution by assuming that VEZP14 acts as a VERL mimic, reducing the intensity of sexual conflict and slowing the co-evolution of lysin and VERL.

Spacetimes containing slowly evolving horizons

Slowly evolving horizons are trapping horizons that are ''almost'' isolated horizons. This paper reviews their definition and discusses several spacetimes containing such structures. These include certain Vaidya and Tolman-Bondi solutions as well as (perturbatively) tidally distorted black holes. Taking into account the mass scales and orders of magnitude that arise in these calculations, we conjecture that slowly evolving horizons are the norm rather than the exception in astrophysical processes that involve stellar-scale black holes

Full Text Available The paper considers an application of analogy in the initial-teacher training as a tool of approaching pedagogical disciplines. The author proposes a classification of pedagogical analogies which provides choices of the most efficient model for a specific didactic situation. The article clarifies the model of the theoretical approach to pedagogical disciplines through active use of analogy, which contributes to a higher efficiency in a teacher and student interaction. The model consists of three stages: training (the stage of acquiring analogy model, the analytical stage (acquisition of pedagogical concepts, phenomena and systems through the application of analogy, and the stage of self-realization (the application of analogy method in students’ scientific-research activities considering external and internal didactic conditions which transform analogy from a teaching method into a tool for the acquisition of pedagogical disciplines. The author demonstrates that the application of analogy has a positive effect not only on the acquisition of pedagogical knowledge (especially methodic and the development of heuristic skills in students, but also on motivation for the study of pedagogical disciplines (cognitive aspect and professional pedagogical activity (formation of an individual-pedagogical attitude. .

Evolvable Neural Software System

Science.gov (United States)

Curtis, Steven A.

2009-01-01

The Evolvable Neural Software System (ENSS) is composed of sets of Neural Basis Functions (NBFs), which can be totally autonomously created and removed according to the changing needs and requirements of the software system. The resulting structure is both hierarchical and self-similar in that a given set of NBFs may have a ruler NBF, which in turn communicates with other sets of NBFs. These sets of NBFs may function as nodes to a ruler node, which are also NBF constructs. In this manner, the synthetic neural system can exhibit the complexity, three-dimensional connectivity, and adaptability of biological neural systems. An added advantage of ENSS over a natural neural system is its ability to modify its core genetic code in response to environmental changes as reflected in needs and requirements. The neural system is fully adaptive and evolvable and is trainable before release. It continues to rewire itself while on the job. The NBF is a unique, bilevel intelligence neural system composed of a higher-level heuristic neural system (HNS) and a lower-level, autonomic neural system (ANS). Taken together, the HNS and the ANS give each NBF the complete capabilities of a biological neural system to match sensory inputs to actions. Another feature of the NBF is the Evolvable Neural Interface (ENI), which links the HNS and ANS. The ENI solves the interface problem between these two systems by actively adapting and evolving from a primitive initial state (a Neural Thread) to a complicated, operational ENI and successfully adapting to a training sequence of sensory input. This simulates the adaptation of a biological neural system in a developmental phase. Within the greater multi-NBF and multi-node ENSS, self-similar ENI s provide the basis for inter-NBF and inter-node connectivity.

NASA HRP Immunology Discipline - Use of Terrestrial Analogs

Science.gov (United States)

Crucian, Brian

2014-01-01

Due to the cost and operational constraints, as well as technical implementation limitations, it is desirous to perform relevant space physiology investigations first in terrestrial 'space analogs'. This is particularly true for initial investigations, which may then provide appropriate focus for subsequent flight investigations, or for mechanistic investigations that simply cannot be performed during spaceflight. Appropriate analog choice is extremely important. There are a wide variety of terrestrial space analogs, each relevant to a particular physiological discipline (or disciplines) and each with a particular fidelity (or lack thereof) to spaceflight, and each with unique operational constraints. The HRP Immunology Discipline is tasked with managing the HRP Risk concerning clinical risk for Astronaut crews related to spaceflight-associated immune dysregulation. Such dysregulation has been documented to occur during spaceflight, and found to persist for the duration of a 6-month ISS mission. Studies continue to characterize the onorbit phenomenon, but it generally consists of diminished immunocyte function, dysregulated cytokine profiles, and persistent herpesvirus reactivation. Causes are thought to synergistically include microgravity, psychological or physiological stress, radiation, and/or circadian misalignment. An appropriate terrestrial analog for immune dysregulation would replicate as many of these influences as possible. Such analogs may include clinostat or bioreactor cell culture (microgravity), hindlimb suspension (stress, fluid shifts, hypokinesis), or human deployment to remote or extreme environments (isolation, stress, circadian). Also, the laboratory setting may be used as an analog, or to augment analogs, such as sleep deprivation/misalignment or human centrifugation to replicate gravitational stress. As an appropriate example of a NASA Disciplines use of Terrestrial space analogs, this talk will discuss spaceflight associated immune

Discipline in chaos: Foucault, dementia and aging in India.

Science.gov (United States)

Brijnath, Bianca; Manderson, Lenore

2008-12-01

In India, care work for people in late-stage dementia is primarily conducted in the home. Using source material from urban India and drawing on Foucauldian theory, we illustrate the significance of three power/knowledge scripts in this context: social and cultural notions of acceptable, public bodies; medicalized forms of care; and the cultural contexts of the individual caregivers. The caregiver is the embodiment of these discourses and is charged with the task of mapping discipline onto inherently undisciplinable bodies. A tension exists between the caregiver's struggle to contain the unruliness of the person with dementia and, simultaneously, to act as a broker between the world of the care-recipient and the social world. We conclude that although the caregiver is the starting point for the exercise of discipline, the three power/knowledge scripts that inform care work are as much about surveying, routinizing and mobilizing caregivers' bodies as they are about disciplining the bodies of people with dementia.

Science.gov (United States)

Schäfer, D; Moog, F P

2005-11-25

300 years ago, the lawyer Theodosius Schöpffer coined the notion gerontology. On this occasion, this paper offers terms and corresponding concepts of gerontology which arose in the western tradition: 1. From the Graeco-Roman antiquity until 1750, gerocomy (the care for the elderly) was defined as a branch of medicine, but in practice almost did not exist. Basically, it provided instructions for a way of life in conformity with the physiological circumstances of elderly people. Its implementation was left to the patient. Furthermore, in the early modern times medical treatises dealt more frequently with diseases of the elderly and their therapy. The gerokomia succeeded in evolving a specific technical literature. Yet it failed to get institutionalized. 2. At the beginning of the 20th century, Ignaz Nascher interpreted geriatrics as a counterpart to pediatrics and opposed it to a clinical-pathological consideration of old age before 1900. He aimed at the exploration and treatment of old age as an autonomous physiological entity. Under the influence of the demographic transformation the institutionalization of geriatrics as a interdisciplinary branch within medicine could be realized relatively soon. 3. Around 1930, we experience the recreation of the notion gerontology, initially restricted to medical gerontology. However, with the integration of the non-medical sciences of old age the spectrum and the objectives changed. Today gerontology signifies on a international level a generic term or independent scientific discipline beside medicine. This evolution corresponds with the intentions pursued 300 years ago.

Evolving phenotypic networks in silico.

François, Paul

2014-11-01

Evolved gene networks are constrained by natural selection. Their structures and functions are consequently far from being random, as exemplified by the multiple instances of parallel/convergent evolution. One can thus ask if features of actual gene networks can be recovered from evolutionary first principles. I review a method for in silico evolution of small models of gene networks aiming at performing predefined biological functions. I summarize the current implementation of the algorithm, insisting on the construction of a proper "fitness" function. I illustrate the approach on three examples: biochemical adaptation, ligand discrimination and vertebrate segmentation (somitogenesis). While the structure of the evolved networks is variable, dynamics of our evolved networks are usually constrained and present many similar features to actual gene networks, including properties that were not explicitly selected for. In silico evolution can thus be used to predict biological behaviours without a detailed knowledge of the mapping between genotype and phenotype. Copyright © 2014 The Author.

An Evolving Identity: How Chronic Care Is Transforming What it Means to Be a Physician.

Science.gov (United States)

Bogetz, Alyssa L; Bogetz, Jori F

2015-12-01

Physician identity and the professional role physicians play in health care is rapidly evolving. Over 130 million adults and children in the USA have complex and chronic diseases, each of which is shaped by aspects of the patient's social, psychological, and economic status. These patients have lifelong health care needs that require the ongoing care of multiple health care providers, access to community services, and the involvement of patients' family support networks. To date, physician professional identity formation has centered on autonomy, authority, and the ability to "heal." These notions of identity may be counterproductive in chronic disease care, which demands interdependency between physicians, their patients, and teams of multidisciplinary health care providers. Medical educators can prepare trainees for practice in the current health care environment by providing training that legitimizes and reinforces a professional identity that emphasizes this interdependency. This commentary outlines the important challenges related to this change and suggests potential strategies to reframe professional identity to better match the evolving role of physicians today.

Decreasing harsh discipline in mothers at risk for maltreatment: a randomized control trial.

Pereira, Mariana; Negrão, Mariana; Soares, Isabel; Mesman, Judi

2014-01-01

This study tested the effectiveness of the attachment-based program Video-feedback Intervention to promote Positive Parenting and Sensitive Discipline (VIPP-SD; F. Juffer, M.J. Bakermans-Kranenburg, & M.H. van IJzendoorn, 2008) in decreasing harsh discipline of 43 mothers and their 1- to 4-year-old-children from severely deprived families. Based on previous studies, parenting stress was tested as a potential moderator of intervention effects on harsh discipline. Using a randomized control design, maternal harsh discipline was observed during home visits at the pretest and posttest, and mothers filled in questionnaires at both assessments. The VIPP-SD proved to be effective in decreasing maternal harsh discipline, but only for mothers who experienced higher levels of parenting stress at intake. These findings provide support for the program's ability to improve parenting in families who are most at risk for harsh parenting and for potentially maltreating child-parent interactions. The results are discussed in terms of the VIPP-SD elements most relevant to decreasing harsh discipline, and the challenges of parenting interventions in severely deprived populations. © 2014 Michigan Association for Infant Mental Health.

Market Discipline and Bank Risk Taking: Evidence from the East Asian Banking Sector

Full Text Available The third pillar of the Basel II highlights the role of market discipline in easing the existing pressure on traditional monitoring measures like capital requirement and government supervision. This study test the effectiveness of market discipline in inducing prudential risk management practices among the East Asian banks over the 1995 to 2005 period. Market discipline is measured using information disclosure and interbank deposit holdings. We find that only the latter is an effective market discipline tool. However, the former becomes effective when market concentration is higher. We find that government owned, foreign owned and recapilatised banks are subject to market disciplining when disclosure in taken account but the opposite is true when interbank deposits is taken into account. Finally, we find that banks that disclose more risk related information hold more capital against their non-performing loan. The implications of the findings are discussed.

Geriatric Cardiology: An Emerging Discipline.

Science.gov (United States)

Dodson, John A; Matlock, Daniel D; Forman, Daniel E

2016-09-01

Given changing demographics, patients with cardiovascular (CV) disease in developed countries are now older and more complex than even a decade ago. This trend is expected to continue into the foreseeable future; accordingly, cardiologists are encountering patients with a greater number of comorbid illnesses as well as "geriatric conditions," such as cognitive impairment and frailty, which complicate management and influence outcomes. Simultaneously, technological advances have widened the therapeutic options available for patients, including those with the most advanced CV disease. In the setting of these changes, geriatric cardiology has recently emerged as a discipline that aims to adapt principles from geriatric medicine to everyday cardiology practice. Accordingly, the tasks of a "geriatric cardiologist" may include both traditional evidence-based CV management plus comprehensive geriatric assessment, medication reduction, team-based coordination of care, and explicit incorporation of patient goals into management. Given that the field is still in its relative infancy, the training pathways and structure of clinical programs in geriatric cardiology are still being delineated. In this review, we highlight the rationale behind geriatric cardiology as a discipline, several current approaches by geriatric cardiology programs, and future directions for the field.

If I shouldn't spank, what should I do? Behavioural techniques for disciplining children.

Science.gov (United States)

Tidmarsh, L

2000-05-01

To provide family physicians with a guide for evaluating discipline problems, giving suggestions for parental guidance, and diagnosing problems when discipline guidance fails. A MEDLINE and PsycINFO search from 1990 to the present produced articles reviewing research on aspects of discipline. Case-control studies, expert opinion, and position statements published by the American Academy of Pediatrics and the Canadian Paediatric Society were chosen as a basis for this article. In a special supplement in 1996, a pediatric journal reviewed the controversy of spanking as an effective disciplinary method, with comments by noted researchers and clinicians. Other authors reviewed research evaluating discipline techniques. Discipline problems require evaluation of children, parents, and parent-child relationships, including assessment of child development and evaluation of parenting skills and parental stressors. Parents can learn techniques more effective than spanking. Physicians can review discipline strategies and guide parents through difficult situations. Monitoring progress is important, and immediate reassessment of the situation if techniques are failing or referral to a specialist will increase the chances of a successful intervention. Discipline problems are complex and require careful assessment. Guiding parents during these types of problems requires close follow up and reevaluation when methods do not have the expected effect.

Discipline strategies and parental perceptions of preschool children with asthma.

Science.gov (United States)

Eiser, C; Eiser, J R; Town, C; Tripp, J H

1991-03-01

Parents of 37 children with asthma (aged between three and five years) and of 37 healthy controls were interviewed about their involvement in everyday care, discipline practices, perceptions of their child and situations which were particularly stressful. There was little correlation between mothers' and fathers' preferences for different discipline practices. There was, however, greater agreement in their perceptions. Parents of children with asthma did not differ from those of healthy controls in discipline practices. However, children with asthma were perceived to be generally less healthy. Parents of those with asthma also reported a greater number of everyday situations to be stressful. These data do not support traditional assumptions that parents of children with asthma are more permissive or overindulgent. At least in this preschool sample, there was only limited indication of adverse effects of chronic disease on parenting practices.

Behavior analysis and neuroscience: Complementary disciplines.

Science.gov (United States)

Donahoe, John W

2017-05-01

Behavior analysis and neuroscience are disciplines in their own right but are united in that both are subfields of a common overarching field-biology. What most fundamentally unites these disciplines is a shared commitment to selectionism, the Darwinian mode of explanation. In selectionism, the order and complexity observed in nature are seen as the cumulative products of selection processes acting over time on a population of variants-favoring some and disfavoring others-with the affected variants contributing to the population on which future selections operate. In the case of behavior analysis, the central selection process is selection by reinforcement; in neuroscience it is natural selection. The two selection processes are inter-related in that selection by reinforcement is itself the product of natural selection. The present paper illustrates the complementary nature of behavior analysis and neuroscience through considering their joint contributions to three central problem areas: reinforcement-including conditioned reinforcement, stimulus control-including equivalence classes, and memory-including reminding and remembering. © 2017 Society for the Experimental Analysis of Behavior.

Science, Linguistique, Littérature : trois disciplines, deux discours, une culture

Directory of Open Access Journals (Sweden)

Sandrine SORLIN

2010-09-01

Full Text Available Cet article propose une réflexion sur les frontières épistémologiques et méthodologiques qui séparent trois disciplines universitaires. Portées par un discours propre à l’économie de leur discipline, la littérature et la science se pensent l’une l’autre comme « deux cultures » antinomiques. Or chaque discipline aborde son objet d’étude à partir d’un paradigme qui est culturellement déterminé. La concomitance de l’apparition des « théories du chaos » en science et du mouvement postmoderne en littérature dans les années 70 par exemple s’explique par leur appartenance à une même culture qui, à un moment donné, a opéré un changement de paradigme informant toutes les disciplines. La linguistique n’y a pas échappé ; pourtant le problème de ses frontières demeure. Nous mettrons en avant la transversalité de cette discipline, laquelle permet - entre autres - de rendre compte non seulement d’un style littéraire mais aussi de ce qu’on peut appeler la « rhétorique » ou la textualité de la science.This paper aims at considering the methodological and epistemological boundaries separating three academic disciplines. Underlain by a discourse that is proper to the economy of their discipline, literature and science regard each other as two opposite cultures. Yet each tackles its object of study through a culturally-determined paradigm. The simultaneous birth of chaos theory in science and postmodern aestheticism in literature in the 70s for instance can only be accounted for if we think of them as belonging to the same culture, which, at some point, brought about a change in paradigm that informed all disciplines. Linguistics underwent the same process. Yet the question of its boundaries remains. We will see to what extent linguistics can be seen as cross-disciplinary, in its study of the rhetoric of both literary and scientific textuality.

A functional polymorphism in the promoter region of the monoamine oxidizing gene monoamine oxidase A (MAOA) has been associated with behavioral sensitivity to adverse environmental conditions in multiple studies (e.g., Caspi et al. 2002; Kim-Cohen et al., 2006). The present study investigates the effects of genotype and early physical discipline on externalizing behavior. We expand on the current literature in our assessment of externalizing, incorporating information across multiple reporters and over a broad developmental time period, and in our understanding of environmental risk. This study uses data from the Child Development Project, an ongoing longitudinal study following a community sample of children beginning at age 5. Physical discipline before age 6 was quantified using a subset of questions from the Conflict Tactics Scale (Straus, 1979). Externalizing behavior was assessed in the male, European-American sub-sample (N = 250) by parent, teacher, and self-report using Achenbach's Child Behavior Checklist, Teacher Report Form, and Youth Self-Report (Achenbach, 1991), at 17 time points from ages 6 to 22. Regression analyses tested the influence of genotype, physical discipline, and their interaction on externalizing behavior, and its subscales, delinquency and aggression. We found a significant interaction effect between genotype and physical discipline on levels of delinquent behavior. Similar trends were observed for aggression and overall externalizing behavior, although these did not reach statistical significance. Main effects of physical discipline held for all outcome variables, and no main effects held for genotype. The adverse consequences of physical discipline on forms of externalizing behavior are exacerbated by an underlying biological risk conferred by MAOA genotype.

Different Strokes for Different Folks: Visual Presentation Design between Disciplines.

2012-12-01

We present an ethnographic study of design differences in visual presentations between academic disciplines. Characterizing design conventions between users and data domains is an important step in developing hypotheses, tools, and design guidelines for information visualization. In this paper, disciplines are compared at a coarse scale between four groups of fields: social, natural, and formal sciences; and the humanities. Two commonplace presentation types were analyzed: electronic slideshows and whiteboard "chalk talks". We found design differences in slideshows using two methods - coding and comparing manually-selected features, like charts and diagrams, and an image-based analysis using PCA called eigenslides. In whiteboard talks with controlled topics, we observed design behaviors, including using representations and formalisms from a participant's own discipline, that suggest authors might benefit from novel assistive tools for designing presentations. Based on these findings, we discuss opportunities for visualization ethnography and human-centered authoring tools for visual information.

Facilitating collaboration among academic generalist disciplines: a call to action.

Kutner, Jean S; Westfall, John M; Morrison, Elizabeth H; Beach, Mary Catherine; Jacobs, Elizabeth A; Rosenblatt, Roger A

2006-01-01

To meet its population's health needs, the United States must have a coherent system to train and support primary care physicians. This goal can be achieved only though genuine collaboration between academic generalist disciplines. Academic general pediatrics, general internal medicine, and family medicine may be hampering this effort and their own futures by lack of collaboration. This essay addresses the necessity of collaboration among generalist physicians in research, medical education, clinical care, and advocacy. Academic generalists should collaborate by (1) making a clear decision to collaborate, (2) proactively discussing the flow of money, (3) rewarding collaboration, (4) initiating regular generalist meetings, (5) refusing to tolerate denigration of other generalist disciplines, (6) facilitating strategic planning for collaboration among generalist disciplines, and (7) learning from previous collaborative successes and failures. Collaboration among academic generalists will enhance opportunities for trainees, primary care research, and advocacy; conserve resources; and improve patient care.

Revisiting Robustness and Evolvability: Evolution in Weighted Genotype Spaces

Science.gov (United States)

Partha, Raghavendran; Raman, Karthik

2014-01-01

Robustness and evolvability are highly intertwined properties of biological systems. The relationship between these properties determines how biological systems are able to withstand mutations and show variation in response to them. Computational studies have explored the relationship between these two properties using neutral networks of RNA sequences (genotype) and their secondary structures (phenotype) as a model system. However, these studies have assumed every mutation to a sequence to be equally likely; the differences in the likelihood of the occurrence of various mutations, and the consequence of probabilistic nature of the mutations in such a system have previously been ignored. Associating probabilities to mutations essentially results in the weighting of genotype space. We here perform a comparative analysis of weighted and unweighted neutral networks of RNA sequences, and subsequently explore the relationship between robustness and evolvability. We show that assuming an equal likelihood for all mutations (as in an unweighted network), underestimates robustness and overestimates evolvability of a system. In spite of discarding this assumption, we observe that a negative correlation between sequence (genotype) robustness and sequence evolvability persists, and also that structure (phenotype) robustness promotes structure evolvability, as observed in earlier studies using unweighted networks. We also study the effects of base composition bias on robustness and evolvability. Particularly, we explore the association between robustness and evolvability in a sequence space that is AU-rich – sequences with an AU content of 80% or higher, compared to a normal (unbiased) sequence space. We find that evolvability of both sequences and structures in an AU-rich space is lesser compared to the normal space, and robustness higher. We also observe that AU-rich populations evolving on neutral networks of phenotypes, can access less phenotypic variation compared to

Subsidiary historical disciplines at Yugoslav and Serbian universities: Their development and perspectives

Directory of Open Access Journals (Sweden)

Atlagić Marko P.

2013-01-01

Full Text Available Subsidiary historical disciplines are an important segment of the studies of history without which the history cannot achieve its main methodological goal. They are available for the purpose of history and historical scientific research. Also, they are of an immense importance for collecting and examining historical sources that is for heuristics. At the same time they are relevant for the judgment regarding choosing, valorization and the use of historical sources, namely for historical critique. In the modern period of the development of teaching history at the universities, subsidiary historical disciplines were consisted mostly of Latin paleography, diplomatics and chronology. Since teaching at universities is being developed, the extension of subsidiary historical disciplines is also being slowly spread on sphragistics and numismatics so that nowadays they include Latin paleography, Slavic paleography, epigraphic, filigranology, diplomatics, chronology, genealogy, sphragistics, numismatics, historical metrology, toponomastics with topography and vexillology. Subsidiary historical disciplines became a part of the programmes for studying history at the end of the XVIII century while they were completely affirmed during the XIX century. However, that practice was not included in Yugoslav and especially not in Serbian universities where subsidiary historical disciplines should have been given the first place in the programmes for studying history as well as in their practical use.

The discipline of accounting has formed many branches,and from it split some independent majors as well,such as financial management,auditing and so on.However,due to lacking of comprehensive thinking and theoretical summary,some of the basic relationships between accounting branches still cannot be explained clearly in theory,thus making people have difficulty in understanding clearly the hierarchical structure of the accounting discipline and the nature and boundary of accounting.The idea of theoretical integration presented by this study is:to reconstruct (or return to) the basic theoretical structure of accounting,and on this basis to establish the basic accounting;to shape some accounting branches through the cross links between the basic accounting and other related disciplines;to form a narrow-sense accounting with the external and internal two information systems of the accounting entity,which should be developed on the basis of the basic accounting;and to integrate such disciplines as the narrow-sense accounting,financial management and auditing into a generalized accounting through the value management of the accounting entity,which is necessary.Some interdisciplinary subjects shaped by the accounting information system with some related crossing disciplines (such as national economic accounting,forensic accounting,etc.) belong to a more generalized accounting.

Reconsidering the role of power, punishment and discipline in South African schools

E. Venter

2011-06-01

Full Text Available This article examines the role of discipline and punishment in South African schools and seeks to interrogate the underlying power relations that guide teaching and learning in South Africa. It deconstructs the pre-occupation with discipline, power and punishment in South African schools in terms of the theoretical framework provided by Michel Foucault in his work entitled “Surveiller et punir: naissance de la prison” (1975 which was translated as “Discipline and punish: the birth of the prison”(1977. It was Foucault who reminded us that the modern school is based on Prussian military ideals of punctuality, discipline, neatness and submissiveness to authority. Foucault tends to see schooling as one side of “corriger”, which is to punish or to teach. Education as “correction” is therefore regarded as the antipode of authoritarian punishment. Foucault draws attention to the subtle tactics and constraints beneath the surface of proclaimed bourgeois freedom. It was found that in South African schools the problem of authoritarian punishment is still rife. From the readings of Foucault’s works suggestions are made for changes to the system and to teachers’ mental attitude in order to move to a more constructive way of maintaining power and discipline.

Numerous studies link harsh discipline to adjustment problems in youth, yet not all individuals exposed to harsh discipline develop behavior problems. Contemporary theory suggests that this relationship could be moderated by individual differences in environmentally sensitive biological systems. This study investigated whether the interaction between hypothalamic-pituitary-adrenal (HPA) activity and autonomic nervous system (ANS) arousal moderated the link between harsh discipline and behavior problems. Three saliva samples were collected on a single day from 425 inner city youth (50% male, age 11-12 years, 80% African American) and were later assayed for cortisol (HPA) and alpha-amylase (ANS). Problem behavior was assessed by self- and parent-report using the Child Behavior Checklist. Youth also reported the level of harsh discipline that they experienced. Harsh discipline was positively associated with externalizing and internalizing problems only when there were asymmetrical profiles of HPA activity and ANS arousal. This pattern was evident for boys but not girls. Findings are discussed in relation to prevailing theories suggesting that biological susceptibility translates adversity into risk for behavior problems. Copyright © 2014 Elsevier B.V.

Flouri, Eirini; Midouhas, Emily

2017-03-01

This study was performed to examine the role of harsh parental discipline in mediating and moderating the effects of environmental adversity (family socioeconomic disadvantage and adverse life events) on emotional and behavioral problems across early-to-middle childhood. The sample included 16,916 children (48% female; 24% non-White) from the U.K.'s Millennium Cohort Study. We analyzed trajectories of conduct, hyperactivity, and emotional problems, measured at ages 3, 5, and 7 years, using growth curve models. Harsh parental discipline was measured at these ages with parent-reported items on the frequency of using the physical and verbal discipline tactics of smacking, shouting at, and "telling off" the child. As expected, family socioeconomic disadvantage and adverse life events were significantly associated with emotional and behavioral problems. Harsh parental discipline was related to children's trajectories of problems, and it moderated, but did not explain, the effect of environmental risk on these trajectories. High-risk children experiencing harsh parental discipline had the highest levels of conduct problems and hyperactivity across the study period. In addition, harsh parental discipline predicted an increase in emotional symptoms over time in high-risk children, unseen in their counterparts experiencing low levels of harsh parental discipline. However, children in low-risk families were also negatively affected by harsh parental discipline concurrently and over time. In conclusion, harsh parental discipline predicted emotional and behavioral problems in high- and low-risk children and moderated the effects of family poverty and adversity on these problems.

Laskey, B J; Cartwright-Hatton, S

2009-09-01

Internalizing disorders of childhood are a common and disabling problem, with sufferers at increased risk of subsequent psychiatric morbidity. Several studies have found associations between parenting styles and children's internalizing, although few have considered the role of parental discipline. Parental discipline style may exert an effect on children's internalizing symptoms. Anxiety and depression are reliably found to run in families and parental anxiety has been shown to effect parenting behaviour. This study set out to examine the links between parental anxiety, parental discipline style and child internalizing symptoms. Eighty-eight parents of children aged 4-10 years were recruited through primary schools. All parents completed questionnaires including measures relating to: adult anxiety (State-Trait Anxiety Inventory - Trait version, Penn State Worry Questionnaire), parental depression (Beck Depression Inventory - Fastscreen), parental discipline (The Parenting Scale), parenting-related attributions (Parenting Attitudes, Beliefs and Cognitions Scale) and child psychological morbidity (Child Behaviour Checklist 4-18 version). Significant correlations were found between both parental anxiety and child internalizing symptoms with ineffective discipline and negative beliefs about parenting. Particularly strong correlations were found between parental anxiety and child internalizing symptoms with harsh discipline. Parents of anxious/withdrawn children were more likely to hold negative beliefs about their child. The link between parental anxiety and child internalizing symptoms was mediated by harsh discipline. The link between parental anxiety and harsh discipline was mediated by parental beliefs about the child. Discipline style may be an important factor in the relationship between parent anxiety and child internalizing symptoms.

The rapidly evolving realm of modern commerce strains traditional regulatory paradigms. This paper traces the historical evolution of FDA crisis-response regulation and provides examples of ways in which the definitions and procedures resulting from that past continue to be challenged by new products as market entrants, some in good faith and others not, take actions that create disconnects between actual product and marketing controls and those that consumers might expect. The paper then explores some of the techniques used by other federal agencies that have faced similar challenges in environments characterized by rapid innovation, and draws from this analysis suggestions for improvement of the FDA's warning letter system.

Two Architects and One Engineer: The Reconciliation of Disciplines

Science.gov (United States)

Belén Gómez Gómez, María

2017-10-01

At the end of the 17th century, when the Académie royale d’architecture was created in France, architecture was studied for the first time from a theoretical and analytical point of view. 100 years later, the École royale des ponts et chaussées was found, also in France. This division of responsibilities within the building discipline varies from country to country and within the specific historical period but, the idea of two professional branches related to architecture, remains to the present day. Through the centuries, this division has been perceived as a problem or as an advantage depending on the specific event, project or construction. However, at the end of the 19th century, when reinforced concrete came into the world of construction, both branches started an interesting collaboration that produced not just marvelous buildings but also helped to evolve architecture. This collaboration started in France and then spread to Spain, Italy and the rest of Europe. As an example of the work that these professionals carried out together was the team formed in the late fifties of the last century by two architects, Bruno Morassutti and Angelo Mangiarotti and an engineer, Aldo Favini. They worked together in Italy projecting amazing and very significant works, such as the Church of Mater Misericordiae which was constructed in Milan between the years 1956 and 1958. One of the main conclusions is that an adequate approach in the collaborative work of architects and engineers, results in impressive and amazing works in which the combination of aesthetic qualities and structural efficiency result in a harmonious building with plenty of significance.

IS IT POSSIBLE TO INTEGRATE BASIC BIOLOGICAL DISCIPLINES IN A PRIVATE INSTITUTION?

Directory of Open Access Journals (Sweden)

L.A. Azzalis

2008-05-01

Full Text Available Basic biological disciplines as biochemistry, genetic and molecular biology have grown faster than any of other sciences. Moreover, those disciplines contribute to the understanding and treatment of an elevated number of illnesses. On the other hand, teachers cannot assure the graduating students that each particular discipline  is essential.  Furthermore,  those disciplines are often studied separately without any interdisciplinary integration between them.  The new curriculum proposed at Anhembi Morumbi University  - a private institution placed at São Paulo city  - incorporates learning blocks that  have been designed to integrate basic biological disciplines and clinical contents from the beginning in order to provide the stimulation and motivation to guide the  student through his learning.  The educational trend has concentrated on the following steps: 1 Biochemistry, genetic, cellular and molecular biology teachers´ from that institution have elaborated a new discipline  that was named Biologic Process. The aim of this new discipline was integrate basic biological sciences in a single content;  2  Selecting problems that could be discussed in the light of biochemistry, genetic and molecular contents; e.g. sickle cell anemia; 3 Developing  an innovative instructional method that challenges students “learn to learn” different from problem-based learning , economically unavailable at any particular university,  and  4 Assessments that measure knowledge, skills, attitudes and beliefs.  We believe that the future pedagogical system in  private health university will be a combination of “classical”  presentation of contents combined with actively involved students in the educational process and instruction based on either hypothetical  or real clinical cases in order to create  the stimulus for  the student continues to  integrate basic and clinical investigation.

Differences in Collaboration Patterns across Discipline, Career Stage, and Gender.

Xiao Han T Zeng

2016-11-01

Full Text Available Collaboration plays an increasingly important role in promoting research productivity and impact. What remains unclear is whether female and male researchers in science, technology, engineering, and mathematical (STEM disciplines differ in their collaboration propensity. Here, we report on an empirical analysis of the complete publication records of 3,980 faculty members in six STEM disciplines at select U.S. research universities. We find that female faculty have significantly fewer distinct co-authors over their careers than males, but that this difference can be fully accounted for by females' lower publication rate and shorter career lengths. Next, we find that female scientists have a lower probability of repeating previous co-authors than males, an intriguing result because prior research shows that teams involving new collaborations produce work with higher impact. Finally, we find evidence for gender segregation in some sub-disciplines in molecular biology, in particular in genomics where we find female faculty to be clearly under-represented.

Maintaining evolvability.

Science.gov (United States)

Crow, James F

2008-12-01

Although molecular methods, such as QTL mapping, have revealed a number of loci with large effects, it is still likely that the bulk of quantitative variability is due to multiple factors, each with small effect. Typically, these have a large additive component. Conventional wisdom argues that selection, natural or artificial, uses up additive variance and thus depletes its supply. Over time, the variance should be reduced, and at equilibrium be near zero. This is especially expected for fitness and traits highly correlated with it. Yet, populations typically have a great deal of additive variance, and do not seem to run out of genetic variability even after many generations of directional selection. Long-term selection experiments show that populations continue to retain seemingly undiminished additive variance despite large changes in the mean value. I propose that there are several reasons for this. (i) The environment is continually changing so that what was formerly most fit no longer is. (ii) There is an input of genetic variance from mutation, and sometimes from migration. (iii) As intermediate-frequency alleles increase in frequency towards one, producing less variance (as p --> 1, p(1 - p) --> 0), others that were originally near zero become more common and increase the variance. Thus, a roughly constant variance is maintained. (iv) There is always selection for fitness and for characters closely related to it. To the extent that the trait is heritable, later generations inherit a disproportionate number of genes acting additively on the trait, thus increasing genetic variance. For these reasons a selected population retains its ability to evolve. Of course, genes with large effect are also important. Conspicuous examples are the small number of loci that changed teosinte to maize, and major phylogenetic changes in the animal kingdom. The relative importance of these along with duplications, chromosome rearrangements, horizontal transmission and polyploidy

Special Aspects of Learning Objectives Design for Disciplines in Engineering Education

Full Text Available The article is devoted to a problem of learning objectives design for disciplines in engineering education. It is shown that the system of well defined objectives can form a basis of discipline content analysis, acquisition control and improvement.The detailed defining of clear objectives and designing forms and content of objectives which allow to estimate their achievement are considered.For this purpose the objectives should consider the level of learners, to designate result which they will be able to show after training, conditions and how well they will be able to make it.Some examples of objective formulations are provided which allow to show in an explicit form the results reached by a learner.It is shown that cognitive process dimension can be divided into groups of initial level of thinking (to remember, understand, apply and thinking of high level (to analyze, estimate, create.Thus knowledge dimension include the factual, conceptual, procedural and metacognitive knowledges.On the basis of cognitive process dimension and knowledge dimension in engineering education it is offered to form system of learning objectives on the basis of their twodimensional classification - taxonomy.Objectives examples for engineering discipline are given. They consider conditions of their achievement and criteria of execution for various combinations of cognitive process dimension and levels of knowledge dimension.For some engineering disciplines examples of learning objectives are formulated including their achievement and criterion of execution of the corresponding actions.The given results can form a basis for design of learning objectives at realization of a competence approach in modern engineering education.Further work in this direction preplan the analysis and approbation of two-dimensional matrix applicability for objectives design on examples of various engineering disciplines.It is of profound importance to use matrixes of well defined

The genotype-phenotype map of an evolving digital organism.

2017-02-01

Full Text Available To understand how evolving systems bring forth novel and useful phenotypes, it is essential to understand the relationship between genotypic and phenotypic change. Artificial evolving systems can help us understand whether the genotype-phenotype maps of natural evolving systems are highly unusual, and it may help create evolvable artificial systems. Here we characterize the genotype-phenotype map of digital organisms in Avida, a platform for digital evolution. We consider digital organisms from a vast space of 10141 genotypes (instruction sequences, which can form 512 different phenotypes. These phenotypes are distinguished by different Boolean logic functions they can compute, as well as by the complexity of these functions. We observe several properties with parallels in natural systems, such as connected genotype networks and asymmetric phenotypic transitions. The likely common cause is robustness to genotypic change. We describe an intriguing tension between phenotypic complexity and evolvability that may have implications for biological evolution. On the one hand, genotypic change is more likely to yield novel phenotypes in more complex organisms. On the other hand, the total number of novel phenotypes reachable through genotypic change is highest for organisms with simple phenotypes. Artificial evolving systems can help us study aspects of biological evolvability that are not accessible in vastly more complex natural systems. They can also help identify properties, such as robustness, that are required for both human-designed artificial systems and synthetic biological systems to be evolvable.

Evolvement of nuclear criticality safety programs

International Nuclear Information System (INIS)

Ketzlach, N.

1992-01-01

Nuclear criticality safety (NCS) has developed from a discipline requiring the services of personnel with only a background in reactor physics to that involving reactor physics, process engineering, and design as well as administration of the program to ensure all its requirements are implemented. When Oak Ridge National Laboratory (ORNL) was designed and constructed, the physicists at Los Alamos National Laboratory (LANL) were performing the criticality analyses. A physicist who had no chemical process or engineering experience was brought in from LANL to determine whether the facility would be safe. It was only because of his understanding of the reactor physics principles, scientific intuition, and some luck that the design and construction of the facility led to a safe plant. It took a number of years of experience with facility operations and the dedication of personnel for NCS to reach its present status as a recognized discipline

Effective but costly, evolved mechanisms of defense against a virulent opportunistic pathogen in Drosophila melanogaster.

Directory of Open Access Journals (Sweden)

Yixin H Ye

2009-04-01

Full Text Available Drosophila harbor substantial genetic variation for antibacterial defense, and investment in immunity is thought to involve a costly trade-off with life history traits, including development, life span, and reproduction. To understand the way in which insects invest in fighting bacterial infection, we selected for survival following systemic infection with the opportunistic pathogen Pseudomonas aeruginosa in wild-caught Drosophila melanogaster over 10 generations. We then examined genome-wide changes in expression in the selected flies relative to unselected controls, both of which had been infected with the pathogen. This powerful combination of techniques allowed us to specifically identify the genetic basis of the evolved immune response. In response to selection, population-level survivorship to infection increased from 15% to 70%. The evolved capacity for defense was costly, however, as evidenced by reduced longevity and larval viability and a rapid loss of the trait once selection pressure was removed. Counter to expectation, we observed more rapid developmental rates in the selected flies. Selection-associated changes in expression of genes with dual involvement in developmental and immune pathways suggest pleiotropy as a possible mechanism for the positive correlation. We also found that both the Toll and the Imd pathways work synergistically to limit infectivity and that cellular immunity plays a more critical role in overcoming P. aeruginosa infection than previously reported. This work reveals novel pathways by which Drosophila can survive infection with a virulent pathogen that may be rare in wild populations, however, due to their cost.

Towards “Operating Within” the Field: Doctoral Students’ Views of Supervisors’ Discipline Expertise

Directory of Open Access Journals (Sweden)

Jan Gube

2017-01-01

Full Text Available Aim/Purpose: This paper considers the role of supervisors’ discipline expertise in doctoral learning from a student perspective. Background:\tDoctoral students need to develop expertise in a particular field of study. In this context, developing expertise requires doctoral students to master disciplinary knowledge, conventions and scholarship under the guidance of supervisors. Methodology\t: The study draws on a mixed-method approach, using an online survey and semi-structured interviews conducted with doctoral students. Contribution: The paper brings to the fore the role of supervisors’ discipline expertise on doctoral students’ research progress. Findings: The survey data suggest that doctoral students nominate their supervisors on the basis of their discipline expertise. They also view supervisors’ expertise as key to the development of ‘insider’ knowledge of their doctoral research. Recommendations for Practitioners: Supervisors play a pivotal role in helping doctoral students overcome intellectual barriers by imparting their discipline knowledge as well as balancing satisfactory doctoral completion rate and high quality student experience. Impact on Society\t: Doctoral supervision equips doctoral students with the right arsenal to be able to competently operate within their field and prepares them for their future research or professional career that demands a high level of discipline expertise. Future Research:\tThe scope of the findings leaves open a discussion about the experiences of doctoral students matched with non-discipline expert supervisory teams; for example, the extent of the mismatch and its ramifications.

A new evolutionary system for evolving artificial neural networks.

Science.gov (United States)

Yao, X; Liu, Y

1997-01-01

This paper presents a new evolutionary system, i.e., EPNet, for evolving artificial neural networks (ANNs). The evolutionary algorithm used in EPNet is based on Fogel's evolutionary programming (EP). Unlike most previous studies on evolving ANN's, this paper puts its emphasis on evolving ANN's behaviors. Five mutation operators proposed in EPNet reflect such an emphasis on evolving behaviors. Close behavioral links between parents and their offspring are maintained by various mutations, such as partial training and node splitting. EPNet evolves ANN's architectures and connection weights (including biases) simultaneously in order to reduce the noise in fitness evaluation. The parsimony of evolved ANN's is encouraged by preferring node/connection deletion to addition. EPNet has been tested on a number of benchmark problems in machine learning and ANNs, such as the parity problem, the medical diagnosis problems, the Australian credit card assessment problem, and the Mackey-Glass time series prediction problem. The experimental results show that EPNet can produce very compact ANNs with good generalization ability in comparison with other algorithms.

Non-axisymmetric features are found in the core collapse of a rapidly rotating massive star, which might have important implications for magnetic field amplification and production of a bipolar outflow that can explode the star, as well as for r-process nucleosynthesis and natal kicks. The collapse of an evolved rapidly rotating MZAMS = 54 M⊙ star is followed in three-dimensional hydrodynamic simulations using the FLASH code with neutrino leakage. A rotating proto-neutron star (PNS) forms with a non-zero linear velocity. This can contribute to the natal kick of the remnant compact object. The PNS is surrounded by a turbulent medium, where high shearing is likely to amplify magnetic fields, which in turn can drive a bipolar outflow. Neutron-rich material in the PNS vicinity might induce strong r-process nucleosynthesis. The rapidly rotating PNS possesses a rotational energy of E_rot ≳ 10^{52} erg. Magnetar formation proceeding in a similar fashion will be able to deposit a portion of this energy later on in the supernova ejecta through a spin-down mechanism. These processes can be important for rare supernovae generated by rapidly rotating progenitors, even though a complete explosion is not simulated in the present study.

Thomas, Scott R.

2011-01-01

The "National Aeronautics Research and Development Policy" document, issued by the National Science and Technology Council in December 2006, stated that one (among several) of the guiding objectives of the federal aeronautics research and development endeavors shall be stable and long-term foundational research efforts. Nearly concurrently, the National Academies issued a more technically focused aeronautics blueprint, entitled: the "Decadal Survey of Civil Aeronautics - Foundations for the Future." Taken together these documents outline the principles of an aeronautics maturation plan. Thus, in response to these overarching inputs (and others), the National Aeronautics and Space Administration (NASA) organized the Fundamental Aeronautics Program (FAP), a program within the NASA Aeronautics Research Mission Directorate (ARMD). The FAP initiated foundational research and technology development tasks to enable the capability of future vehicles that operate across a broad range of Mach numbers, inclusive of the subsonic, supersonic, and hypersonic flight regimes. The FAP Hypersonics Project concentrates on two hypersonic missions: (1) Air-breathing Access to Space (AAS) and (2) the (Planetary Atmospheric) Entry, Decent, and Landing (EDL). The AAS mission focuses on Two-Stage-To-Orbit (TSTO) systems using air-breathing combined-cycle-engine propulsion; whereas, the EDL mission focuses on the challenges associated with delivering large payloads to (and from) Mars. So, the FAP Hypersonic Project investments are aligned to achieve mastery and intellectual stewardship of the core competencies in the hypersonic-flight regime, which ultimately will be required for practical systems with highly integrated aerodynamic/vehicle and propulsion/engine technologies. Within the FAP Hypersonics, the technology management is further divided into disciplines including one targeting Turbine-Based Combine-Cycle (TBCC) propulsion. Additionally, to obtain expertise and support from outside

Full Text Available Sustainable development is an objective for humanity of crucial importance to how we develop and evolve. It is also a rapidly growing discipline that is becoming increasingly applied in numerous areas, reflecting humanity's desire to ensure its activities can be sustained into the future and do not adversely affect the ecology or environment. Sustainable development is often defined based on the 1987 statement of the World Commission on Environment and Development (i.e., the Brundtland Commission. In that milestone document, sustainable development was defined as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs." But new definitions are being developed as the discipline expands and becomes more multidisciplinary and complex.

Full Text Available Abstract Background Mammalian genome sequence data are being acquired in large quantities and at enormous speeds. We now have a tremendous opportunity to better understand which genes are the most variable or conserved, and what their particular functions and evolutionary dynamics are, through comparative genomics. Results We chose human and eleven other high-coverage mammalian genome data–as well as an avian genome as an outgroup–to analyze orthologous protein-coding genes using nonsynonymous (Ka and synonymous (Ks substitution rates. After evaluating eight commonly-used methods of Ka and Ks calculation, we observed that these methods yielded a nearly uniform result when estimating Ka, but not Ks (or Ka/Ks. When sorting genes based on Ka, we noticed that fast-evolving and slow-evolving genes often belonged to different functional classes, with respect to species-specificity and lineage-specificity. In particular, we identified two functional classes of genes in the acquired immune system. Fast-evolving genes coded for signal-transducing proteins, such as receptors, ligands, cytokines, and CDs (cluster of differentiation, mostly surface proteins, whereas the slow-evolving genes were for function-modulating proteins, such as kinases and adaptor proteins. In addition, among slow-evolving genes that had functions related to the central nervous system, neurodegenerative disease-related pathways were enriched significantly in most mammalian species. We also confirmed that gene expression was negatively correlated with evolution rate, i.e. slow-evolving genes were expressed at higher levels than fast-evolving genes. Our results indicated that the functional specializations of the three major mammalian clades were: sensory perception and oncogenesis in primates, reproduction and hormone regulation in large mammals, and immunity and angiotensin in rodents. Conclusion Our study suggests that Ka calculation, which is less biased compared to Ks and Ka

Information Literacy for Multiple Disciplines: Toward a Campus-Wide Integration Model at Indiana University, Bloomington

2011-11-01

Full Text Available Within disciplines are a set of shared values and thought processes that students must master in order to become participants of that discipline. Information literacy as defined by the ACRL is a set of standards and principles that can apply to all disciplines. In order to produce information literate undergraduates in a given discipline, information literacy standards must be integrated with the values and processes of the discipline. In this study, librarians partnered with faculty in gender studies and molecular biology to integrate information literacy with courses in those areas. Student performance and attitudes improved as a result of the collaboration. This article discusses the collaboration process, the assessment methods and results, and the long-term importance of developing best practices for information literacy integration at the campus level through a disciplinary approach.

2015-08-01

Full Text Available Introduction: The current students generation are daily connected to the Internet, wich encourages the use of mobile tools in education. Many of the students of Biochemistry feel apprehensive about the discipline and the use of facebook may contribute, among other factors, motivating them. Objectives: It was analyzed the use of facebook as a mediator and motivator in the discipline of Biochemistry, basing on socioconstrutivist interventions. Material and methods: This work was developed in the action-research perspective, using the quali-quantitative method. An investigative questionnaire was used, using Likert scale and open questions, to investigate the facebook use, as well as the preferences of students, focusing on Biochemistry group in the Biomedicine course.  The posts were analyzed identifying: frequency of the interaction`s types (post, comment, likes;  interaction's categories (question, answer, motivational; and the content itself of the post. Results: It was highlighted students' interest to search materials, answering questions, and especially seeking information about the discipline. It was emphasized that the group was motivating for learning Biochemistry, encouragement the group to study, with quick and easy access to the professor by chat. Conclusions: The results indicate a preference for students at facebook, with a great motivational potential, is at easy access to colleagues, professor and monitor, or even the ease of obtaining the materials and ask questions in real time, indicating that this tool as a possible way, still little explored, to enhance the teaching of Biochemistry.

Computational statistics and biometry: which discipline drives which?

Directory of Open Access Journals (Sweden)

Edler, Lutz

2005-06-01

Full Text Available A biometrician's work is defined through the biological or medical problem and the mathematical and statistical methods needed for its solution. This requires in most instances statistical data analysis and the use of methods of computational statistics. At first, it seems quite obvious that the computational needs of the biometric problem determine what has to be developed by the discipline of computational statistics. However, viewing the development of biometry and computational statistics in Germany for the past decades in more details reveals an interesting interaction between the activities of the German Region of the International Biometric Society and groups engaged in computational statistics within Germany. Exact methods of statistical inference and permutation tests, simulations and the use of the Bootstrap, and interactive graphical statistical methods are examples of this fruitful reciprocal benefit. This contribution examines therefore relationships between the historical development of biometry and computational statistics in Germany using as sources of information contributions to the scientific literature, presentations and sessions at scientific conferences on biometry and on computational statistics which influenced the development of both disciplines and exhibits a reciprocal dependency. The annual workshops organized on the Reisensburg now for more than 30 years are recognized as an outstanding factor of this interrelationship. This work aims at the definition of the present status of computational statistics in the German Region of the International Biometric Society and intends to guide and to foster the discussion of the future development of this discipline among biometricians.

Co-regulation of a large and rapidly evolving repertoire of odorant receptor genes

Directory of Open Access Journals (Sweden)

Lane Robert P

2007-09-01

Full Text Available Abstract The olfactory system meets niche- and species-specific demands by an accelerated evolution of its odorant receptor repertoires. In this review, we describe evolutionary processes that have shaped olfactory and vomeronasal receptor gene families in vertebrate genomes. We emphasize three important periods in the evolution of the olfactory system evident by comparative genomics: the adaptation to land in amphibian ancestors, the decline of olfaction in primates, and the delineation of putative pheromone receptors concurrent with rodent speciation. The rapid evolution of odorant receptor genes, the sheer size of the repertoire, as well as their wide distribution in the genome, presents a developmental challenge: how are these ever-changing odorant receptor repertoires coordinated within the olfactory system? A central organizing principle in olfaction is the specialization of sensory neurons resulting from each sensory neuron expressing only ~one odorant receptor allele. In this review, we also discuss this mutually exclusive expression of odorant receptor genes. We have considered several models to account for co-regulation of odorant receptor repertoires, as well as discussed a new hypothesis that invokes important epigenetic properties of the system.

Caban, Jesus J; Joshi, Alark; Nagy, Paul

2007-11-01

Rapid prototyping is an important element in researching new imaging analysis techniques and developing custom medical applications. In the last ten years, the open source community and the number of open source libraries and freely available frameworks for biomedical research have grown significantly. What they offer are now considered standards in medical image analysis, computer-aided diagnosis, and medical visualization. A cursory review of the peer-reviewed literature in imaging informatics (indeed, in almost any information technology-dependent scientific discipline) indicates the current reliance on open source libraries to accelerate development and validation of processes and techniques. In this survey paper, we review and compare a few of the most successful open source libraries and frameworks for medical application development. Our dual intentions are to provide evidence that these approaches already constitute a vital and essential part of medical image analysis, diagnosis, and visualization and to motivate the reader to use open source libraries and software for rapid prototyping of medical applications and tools.

Evolution under changing climates: climatic niche stasis despite rapid evolution in a non-native plant.

Science.gov (United States)

Alexander, Jake M

2013-09-22

A topic of great current interest is the capacity of populations to adapt genetically to rapidly changing climates, for example by evolving the timing of life-history events, but this is challenging to address experimentally. I use a plant invasion as a model system to tackle this question by combining molecular markers, a common garden experiment and climatic niche modelling. This approach reveals that non-native Lactuca serriola originates primarily from Europe, a climatic subset of its native range, with low rates of admixture from Asia. It has rapidly refilled its climatic niche in the new range, associated with the evolution of flowering phenology to produce clines along climate gradients that mirror those across the native range. Consequently, some non-native plants have evolved development times and grow under climates more extreme than those found in Europe, but not among populations from the native range as a whole. This suggests that many plant populations can adapt rapidly to changed climatic conditions that are already within the climatic niche space occupied by the species elsewhere in its range, but that evolution to conditions outside of this range is more difficult. These findings can also help to explain the prevalence of niche conservatism among non-native species.

2009-01-01

What happens to scientific knowledge when researchers outside the natural sciences bring elements of the latest trend across disciplinary boundaries for their own purposes? Researchers in fields from anthropology to family therapy and traffic planning employ the concepts, methods, and results of chaos theory to harness the disciplinary prestige of the natural sciences, to motivate methodological change or conceptual reorganization within their home discipline, and to justify public policies and aesthetic judgments.Using the recent explosion in the use (and abuse) of chaos theory, Borrowed Knowledge and the Challenge of Learning across Disciplines examines the relationship between science and other disciplines as well as the place of scientific knowledge within our broader culture. Stephen H.

Understanding the nineteenth century origins of disciplines: lessons for astrobiology today?

Science.gov (United States)

Brazelton, William J.; Sullivan, Woodruff T., III

2009-10-01

Astrobiology's goal of promoting interdisciplinary research is an attempt to reverse a trend that began two centuries ago with the formation of the first specialized scientific disciplines. We have examined this era of discipline formation in order to make a comparison with the situation today in astrobiology. Will astrobiology remain interdisciplinary or is it becoming yet another specialty? As a case study, we have investigated effects on the scientific literature when a specialized community is formed by analyzing the citations within papers published during 1802-1856 in Philosophical Transactions of the Royal Society (Phil. Trans.), the most important ‘generalist’ journal of its day, and Transactions of the Geological Society of London (Trans. Geol. Soc.), the first important disciplinary journal in the sciences. We find that these two journals rarely cited each other, and papers published in Trans. Geol. Soc. cited fewer interdisciplinary sources than did geology papers in Phil. Trans. After geology had become established as a successful specialized discipline, geologists returned to publishing papers in Phil. Trans., but they wrote in the new, highly specialized style developed in Trans. Geol. Soc. They had succeeded in not only creating a new scientific discipline, but also a new way of doing science with its own modes of research and communication. A similar citation analysis was applied to papers published over the period 2001-2008 in the contemporary journals Astrobiology and the International Journal of Astrobiology to test the hypothesis that astrobiologists are in the early stages of creating their own specialized community. Although still too early to reliably detect any but the largest trends, there is no evidence yet that astrobiologists are drifting into their own isolated discipline. Instead, to date they appear to remain interdisciplinary.

Applying behavior analysis to school violence and discipline problems: Schoolwide positive behavior support

Science.gov (United States)

Anderson, Cynthia M.; Kincaid, Donald

2005-01-01

School discipline is a growing concern in the United States. Educators frequently are faced with discipline problems ranging from infrequent but extreme problems (e.g., shootings) to less severe problems that occur at high frequency (e.g., bullying, insubordination, tardiness, and fighting). Unfortunately, teachers report feeling ill prepared to deal effectively with discipline problems in schools. Further, research suggests that many commonly used strategies, such as suspension, expulsion, and other reactive strategies, are not effective for ameliorating discipline problems and may, in fact, make the situation worse. The principles and technology of behavior analysis have been demonstrated to be extremely effective for decreasing problem behavior and increasing social skills exhibited by school children. Recently, these principles and techniques have been applied at the level of the entire school, in a movement termed schoolwide positive behavior support. In this paper we review the tenets of schoolwide positive behavior support, demonstrating the relation between this technology and applied behavior analysis. PMID:22478439

Full Text Available This study elaborated relations between digital library use by university faculty, users' discipline and the availability of key resources in the Finnish National Electronic Library (FinELib, Finnish national digital library, by using nationwide representative survey data. The results show that the perceived availability of key electronic resources by researchers in FinELib was a stronger predictor of the frequency and purpose of use of its services than users' discipline. Regardless of discipline a good perceived provision of central resources led to a more frequent use of FinELib. The satisfaction with the services did not vary with the discipline, but with the perceived availability of resources.

Isotope hydrology: applied discipline in earth sciences

1998-01-01

The discipline 'isotope hydrology' is being reviewed from the perspective of the Isotope Hydrology Section of the International Atomic Energy Agency in Vienna. The Section was created in the late fifties and is activities involved int the scientific progress of the discipline. The role of the IAEA in the development of isotope hydrology has always been of a dual nature: on one hand, the Section has been and still is heavily engaged in supporting and coordinating further development of isotope methodologies, on the other hand, it serves as an interface between the methodological development in research institutes and the applied work using proven techniques in field projects on water resources assessment and management. The paper provides a brief overview of applications of isotope-based methodologies in hydrology, with emphasis on new trends and challenges related to man's growing impact on the water cycle. This contribution is a tribute to the memory of the former Head of the Isotope Hydrology Section, Jean-Charles Fontes, to whom we owe so much. (authors)

Molecular evolution in court: analysis of a large hepatitis C virus outbreak from an evolving source.

González-Candelas, Fernando; Bracho, María Alma; Wróbel, Borys; Moya, Andrés

2013-07-19

Molecular phylogenetic analyses are used increasingly in the epidemiological investigation of outbreaks and transmission cases involving rapidly evolving RNA viruses. Here, we present the results of such an analysis that contributed to the conviction of an anesthetist as being responsible for the infection of 275 of his patients with hepatitis C virus. We obtained sequences of the NS5B and E1-E2 regions in the viral genome for 322 patients suspected to have been infected by the doctor, and for 44 local, unrelated controls. The analysis of 4,184 cloned sequences of the E1-E2 region allowed us to exclude 47 patients from the outbreak. A subset of patients had known dates of infection. We used these data to calibrate a relaxed molecular clock and to determine a rough estimate of the time of infection for each patient. A similar analysis led to an estimate for the time of infection of the source. The date turned out to be 10 years before the detection of the outbreak. The number of patients infected was small at first, but it increased substantially in the months before the detection of the outbreak. We have developed a procedure to integrate molecular phylogenetic reconstructions of rapidly evolving viral populations into a forensic setting adequate for molecular epidemiological analysis of outbreaks and transmission events. We applied this procedure to a large outbreak of hepatitis C virus caused by a single source and the results obtained played a key role in the trial that led to the conviction of the suspected source.

Orbital Decay in Binaries with Evolved Stars

Sun, Meng; Arras, Phil; Weinberg, Nevin N.; Troup, Nicholas; Majewski, Steven R.

2018-01-01

Two mechanisms are often invoked to explain tidal friction in binary systems. The ``dynamical tide” is the resonant excitation of internal gravity waves by the tide, and their subsequent damping by nonlinear fluid processes or thermal diffusion. The ``equilibrium tide” refers to non-resonant excitation of fluid motion in the star’s convection zone, with damping by interaction with the turbulent eddies. There have been numerous studies of these processes in main sequence stars, but less so on the subgiant and red giant branches. Motivated by the newly discovered close binary systems in the Apache Point Observatory Galactic Evolution Experiment (APOGEE-1), we have performed calculations of both the dynamical and equilibrium tide processes for stars over a range of mass as the star’s cease core hydrogen burning and evolve to shell burning. Even for stars which had a radiative core on the main sequence, the dynamical tide may have very large amplitude in the newly radiative core in post-main sequence, giving rise to wave breaking. The resulting large dynamical tide dissipation rate is compared to the equilibrium tide, and the range of secondary masses and orbital periods over which rapid orbital decay may occur will be discussed, as well as applications to close APOGEE binaries.

Here a discrete event simulation (DES) model to analyze the cost-effectiveness of natalizumab and fingolimod in the RES population, from the perspective of the National Health Service (NHS) in the UK, is reported. A DES model was developed to track individual RES patients, based on Expanded Disability Status Scale scores. Individual patient characteristics were taken from the RES sub-groups of the pivotal trials for fingolimod. Utility data were in line with previous models. Published costs were inflated to NHS cost year 2015. Owing to the confidential patient access scheme (PAS) discount applied to fingolimod in the UK, a range of discount levels were applied to the fingolimod list price, to capture the likelihood of natalizumab being cost-effective in a real-world setting. At the lower National Institute of Health and Care Excellence (NICE) threshold of £20,000/quality-adjusted life year (QALY), fingolimod only required a discount greater than 0.8% of list price to be cost-effective. At the upper threshold of £30,000/QALY employed by the NICE, fingolimod was cost-effective if the confidential discount is greater than 2.5%. Sensitivity analyses conducted using fingolimod list-price showed the model to be most sensitive to changes in the cost of each drug, particularly fingolimod. The DES model shows that only a modest discount to the UK fingolimod list-price is required to make fingolimod a more cost-effective option than natalizumab in RES RRMS.

Random mutagenesis has the potential to optimize the efficiency and selectivity of protein catalysts without requiring detailed knowledge of protein structure; however, introducing synthetic metal cofactors complicates the expression and screening of enzyme libraries, and activity arising from free cofactor must be eliminated. Here we report an efficient platform to create and screen libraries of artificial metalloenzymes (ArMs) via random mutagenesis, which we use to evolve highly selective dirhodium cyclopropanases. Error-prone PCR and combinatorial codon mutagenesis enabled multiplexed analysis of random mutations, including at sites distal to the putative ArM active site that are difficult to identify using targeted mutagenesis approaches. Variants that exhibited significantly improved selectivity for each of the cyclopropane product enantiomers were identified, and higher activity than previously reported ArM cyclopropanases obtained via targeted mutagenesis was also observed. This improved selectivity carried over to other dirhodium-catalysed transformations, including N-H, S-H and Si-H insertion, demonstrating that ArMs evolved for one reaction can serve as starting points to evolve catalysts for others.

Consumer Health Informatics: Past, Present, and Future of a Rapidly Evolving Domain.

Science.gov (United States)

Demiris, G

2016-05-20

Consumer Health Informatics (CHI) is a rapidly growing domain within the field of biomedical and health informatics. The objective of this paper is to reflect on the past twenty five years and showcase informatics concepts and applications that led to new models of care and patient empowerment, and to predict future trends and challenges for the next 25 years. We discuss concepts and systems based on a review and analysis of published literature in the consumer health informatics domain in the last 25 years. The field was introduced with the vision that one day patients will be in charge of their own health care using informatics tools and systems. Scientific literature in the field originally focused on ways to assess the quality and validity of available printed health information, only to grow significantly to cover diverse areas such as online communities, social media, and shared decision-making. Concepts such as home telehealth, mHealth, and the quantified-self movement, tools to address transparency of health care organizations, and personal health records and portals provided significant milestones in the field. Consumers are able to actively participate in the decision-making process and to engage in health care processes and decisions. However, challenges such as health literacy and the digital divide have hindered us from maximizing the potential of CHI tools with a significant portion of underserved populations unable to access and utilize them. At the same time, at a global scale consumer tools can increase access to care for underserved populations in developing countries. The field continues to grow and emerging movements such as precision medicine and the sharing economy will introduce new opportunities and challenges.

The evolution of resource adaptation: how generalist and specialist consumers evolve.

Science.gov (United States)

Ma, Junling; Levin, Simon A

2006-07-01

Why and how specialist and generalist strategies evolve are important questions in evolutionary ecology. In this paper, with the method of adaptive dynamics and evolutionary branching, we identify conditions that select for specialist and generalist strategies. Generally, generalist strategies evolve if there is a switching benefit; specialists evolve if there is a switching cost. If the switching cost is large, specialists always evolve. If the switching cost is small, even though the consumer will first evolve toward a generalist strategy, it will eventually branch into two specialists.

Black students are issued school discipline sanctions at rates higher than members of other racial and ethnic groups, underscoring the need for professional development that addresses this gap. In 86 secondary classrooms, a randomized controlled trial examined the effects of a 2-year teacher coaching program, My Teaching Partner Secondary (MTP-S). Results from the second year of coaching and the year after coaching was discontinued replicated previous findings from the first year of coaching—intervention teachers had no significant disparities in discipline referral between Black students and their classmates, compared to teachers in the control condition, for whom racial discipline gaps remained. Thus, MTP-S effects were replicated in the second year of coaching and maintained when coaching was withdrawn. Mediational analyses identified mechanisms for these effects; Black students had a low probability of receiving disciplinary referrals with teachers who increased skills to engage students in high-level analysis and inquiry.

Phillips, Kelly N; Castillo, Gerardo; Wünsche, Andrea; Cooper, Tim F

2016-02-01

The selective history of a population can influence its subsequent evolution, an effect known as historical contingency. We previously observed that five of six replicate populations that were evolved in a glucose-limited environment for 2000 generations, then switched to lactose for 1000 generations, had higher fitness increases in lactose than populations started directly from the ancestor. To test if selection in glucose systematically increased lactose evolvability, we started 12 replay populations--six from a population subsample and six from a single randomly selected clone--from each of the six glucose-evolved founder populations. These replay populations and 18 ancestral populations were evolved for 1000 generations in a lactose-limited environment. We found that replay populations were initially slightly less fit in lactose than the ancestor, but were more evolvable, in that they increased in fitness at a faster rate and to higher levels. This result indicates that evolution in the glucose environment resulted in genetic changes that increased the potential of genotypes to adapt to lactose. Genome sequencing identified four genes--iclR, nadR, spoT, and rbs--that were mutated in most glucose-evolved clones and are candidates for mediating increased evolvability. Our results demonstrate that short-term selective costs during selection in one environment can lead to changes in evolvability that confer longer term benefits. © 2016 The Author(s).

Uluslararası İlişkiler Disiplininin Oluşumu: İdealizm / Realizm Tartışması ve Disiplinin Özerkliği = Formation of International Relations Discipline: Idealism / Realism Debate and Autonomy of the Discipline

Directory of Open Access Journals (Sweden)

Davut ATEŞ

2009-01-01

Full Text Available International Relations discipline has a short history in comparison to other disciplines in social sciences. Even if it is widely accepted that modern international relations had begun with the Treaty of Westphalia in 1648, this kind of relations had been examined within law, history and political science for a long time. Today there is a great consensus that autonomy of the discipline, which began to appear as a separate field only after the First World War, has established. In this article, formative stage of disciplinary and theoretical autonomy of the discipline will be examined in conjunction with idealism/realism debate of the first period; without questioning the validity of assumptions of in this debate it will be tried to clarify how it prepared a framework for the autonomy of the discipline.

Rapid evolution of the sequences and gene repertoires of secreted proteins in bacteria.

Directory of Open Access Journals (Sweden)

Teresa Nogueira

Full Text Available Proteins secreted to the extracellular environment or to the periphery of the cell envelope, the secretome, play essential roles in foraging, antagonistic and mutualistic interactions. We hypothesize that arms races, genetic conflicts and varying selective pressures should lead to the rapid change of sequences and gene repertoires of the secretome. The analysis of 42 bacterial pan-genomes shows that secreted, and especially extracellular proteins, are predominantly encoded in the accessory genome, i.e. among genes not ubiquitous within the clade. Genes encoding outer membrane proteins might engage more frequently in intra-chromosomal gene conversion because they are more often in multi-genic families. The gene sequences encoding the secretome evolve faster than the rest of the genome and in particular at non-synonymous positions. Cell wall proteins in Firmicutes evolve particularly fast when compared with outer membrane proteins of Proteobacteria. Virulence factors are over-represented in the secretome, notably in outer membrane proteins, but cell localization explains more of the variance in substitution rates and gene repertoires than sequence homology to known virulence factors. Accordingly, the repertoires and sequences of the genes encoding the secretome change fast in the clades of obligatory and facultative pathogens and also in the clades of mutualists and free-living bacteria. Our study shows that cell localization shapes genome evolution. In agreement with our hypothesis, the repertoires and the sequences of genes encoding secreted proteins evolve fast. The particularly rapid change of extracellular proteins suggests that these public goods are key players in bacterial adaptation.

Discipline-Specific Language Instruction for International Students in Introductory Economics

Directory of Open Access Journals (Sweden)

Trien T. Nguyen

2015-12-01

Full Text Available This paper explores student perceptions of the effects of pairing discipline-specific language instruction with the traditional method of course delivery in economics. Our research involved teaching content-based English as an additional language (EAL tutorials to a small group of ten international students taking first-year introductory economics courses. These voluntary participants completed pre- and post-treatment assessments with exit interviews at the end of the project. Assessment results and interviews suggest that students perceive that discipline-specific language instruction such as our EAL tutorials assists in the development of increased content and language proficiency. They also believe that vocabulary development is one of the most critical activities to support these goals; reading skills are also important but require more time and commitment than students can afford to give. Despite the students’ interest in the project, their heavy class schedules prevented many from participating; our group was limited to ten students which precludes any assurance of statistical significance. In spite of the limitations, we believe that the project can still contribute valuable qualitative lessons to the literature of content-based language instruction in which the discipline of economics has not been well represented.

Non-lane-discipline-based car-following model under honk environment

Science.gov (United States)

Rong, Ying; Wen, Huiying

2018-04-01

This study proposed a non-lane-discipline-based car-following model by synthetically considering the visual angles and the timid/aggressive characteristics of drivers under honk environment. We firstly derived the neutral stability condition by the linear stability theory. It showed that the parameters related to visual angles and driving characteristics of drivers under honk environment all have significant impact on the stability of non-lane-discipline traffic flow. For better understanding the inner mechanism among these factors, we further analyzed how each parameter affects the traffic flow and gained further insight into how the visual angles information influences other parameters and then influences the non-lane-discipline traffic flow under honk environment. And the results showed that the other aspects such as driving characteristics of drivers or honk effect are all interacted with the "Visual-Angle Factor". And the effect of visual angle is not just to say simply it has larger stable region or not as the existing studies. Finally, to verify the proposed model, we carried out the numerical simulation under the periodic boundary condition. And the results of numerical simulation are agreed well with the theoretical findings.

Lessons Learned by Comparing On-line Education Strategies Across Disciplines

Directory of Open Access Journals (Sweden)

Stephen H. Edwards

2004-12-01

Full Text Available When choosing how best to employ educational technologies for on-line learning, there is much to be gained by examining the experience of educators in other disciplines. This paper presents four brief case studies in the disciplines of computer science and social work. Lessons learned by comparing these diverse experiences are discussed, including creating a community of learners, supporting asynchronous student communication, using synchronous on-line meetings, and providing social support. In addition, the experiences presented indicate that stereotypes of student capabilities and expectations may often be inaccurate, and revising one's views may be helpful in achieving better results in on-line education.

Conservation Biology and Traditional Ecological Knowledge: Integrating Academic Disciplines for Better Conservation Practice

Directory of Open Access Journals (Sweden)

Joshua A. Drew

2006-12-01

Full Text Available Conservation biology and environmental anthropology are disciplines that are both concerned with the identification and preservation of diversity, in one case biological and in the other cultural. Both conservation biology and the study of traditional ecoloigcal knowledge function at the nexus of the social and natural worlds, yet historically there have been major impediments to integrating the two. Here we identify linguistic, cultural, and epistemological barriers between the two disciplines. We argue that the two disciplines are uniquely positioned to inform each other and to provide critical insights and new perspectives on the way these sciences are practiced. We conclude by synthesizing common themes found in conservation success stories, and by making several suggestions on integration. These include cross-disciplinary publication, expanding memberships in professional societies and conducting multidisciplinary research based on similar interests in ecological process, taxonomy, or geography. Finally, we argue that extinction threats, be they biological or cultural/linguistic are imminent, and that by bringing these disciplines together we may be able to forge synergistic conservation programs capable of protecting the vivid splendor of life on Earth.

Racial Discipline Disproportionality in Montessori and Traditional Public Schools: A Comparative Study Using the Relative Rate Index

Directory of Open Access Journals (Sweden)

Katie E. Brown

2015-11-01

Full Text Available Research from the past 40 years indicates that African American students are subjected to exclusionary discipline, including suspension and expulsion, at rates two to three times higher than their White peers (Children’s Defense Fund, 1975; Skiba, Michael, Nardo, & Peterson, 2002. Although this phenomenon has been studied extensively in traditional public schools, rates of racially disproportionate discipline in public Montessori schools have not been examined. The purpose of this study is to examine racial discipline disproportionality in Montessori public elementary schools as compared to traditional elementary schools. The Relative Rate Index (RRI is used as a measure of racially disproportionate use of out-of-school suspensions (Tobin & Vincent, 2011. Suspension data from the Office of Civil Rights Data Collection was used to generate RRIs for Montessori and traditional elementary schools in a large urban district in the Southeast. While statistically significant levels of racial discipline disproportionality are found in both the Montessori and traditional schools, the effect is substantially less pronounced in Montessori settings. These findings suggest that Montessori schools are not immune to racially disproportionate discipline and should work to incorporate more culturally responsive classroom management techniques. Conversely, the lower levels of racially disproportionate discipline in the Montessori schools suggests that further study of discipline in Montessori environments may provide lessons for traditional schools to promote equitable discipline.

2010-01-01

Using data from 195 dyads of mothers and children (age range = 8–12 years; M = 10.63) in four countries (China, India, the Philippines, and Thailand), this study examined children’s perceptions of maternal hostility as a mediator of the links between physical discipline and harsh verbal discipline and children’s adjustment. Both physical discipline and harsh verbal discipline had direct effects on mothers’ reports of children’s anxiety and aggression; three of these four links were mediated by children’s perceptions of maternal hostility. In contrast, there were no significant direct effects of physical discipline and harsh verbal discipline on children’s reports of their own anxiety and aggression. Instead, both physical discipline and harsh verbal discipline had indirect effects on the outcomes through children’s perceptions of maternal hostility. We identified a significant interaction between perceived normativeness and use of harsh verbal discipline on children’s perception of maternal hostility, but children’s perception of the normativeness of physical discipline did not moderate the relation between physical discipline and perceived maternal hostility. The effects of harsh verbal discipline were more adverse when children perceived that form of discipline as being nonnormative than when children perceived that form of discipline as being normative. Results are largely consistent with a theoretical model positing that the meaning children attach to parents’ discipline strategies is important in understanding associations between discipline and children’s adjustment, and that cultural context is associated with children’s interpretations of their parents’ behavior.

Jeab at 50: coevolution of research and technology.

Science.gov (United States)

Lattal, Kennon A

2008-01-01

Evidence of how behavioral research and technology have evolved together abounds in the history of the Journal of the Experimental Analysis of Behavior (JEAB). Technology from outside the discipline (exogenous), from such disciplines as electronics and computer science, has been adapted for use in behavioral research. Technology from within the discipline (endogenous) has developed from both basic behavioral research and existing apparatus. All of these sources of technology have contributed to the corpus of behavioral research as it has evolved in JEAB. Such research, in turn, has provided the environmental pressure necessary for continuing technological evolution both within and outside the discipline. The new technology thus evolved further spurs research along in novel directions. This dynamic coevolutionary interplay between research and technology is an important variable in the past, present, and future of JEAB.

Writing disciplines: producing disciplinary knowledge in the context of contemporary higher education

Directory of Open Access Journals (Sweden)

Karin Tusting

2016-11-01

Full Text Available This paper addresses academic disciplinary writing practices, and how these are affected by changes in the landscape of Higher Education in the UK. After exploring the definition and understanding of the notion of “discipline”, the paper presents research from an ESRC-funded research project studying academics’ everyday writing practices, working closely with academics across different disciplines and different kinds of higher education institutions. The changing context of Higher Education in the UK is presented, in particular the emergence of new kinds of managerial practices which shape and co-ordinate the everyday writing work of academics. The paper shows that while some disciplines, such as History and Pure Mathematics, are associated with clearly-defined writing practices, others are more diverse. It discusses how managerial practices, particularly those driven by centralised national research evaluations, affect different disciplines in different ways.

History of Physics Education Research as a Model for Geoscience Education Research Community Progress

Science.gov (United States)

Slater, T. F.

2011-12-01

Discipline-based Education Research (DBER) is a research field richly combining a deep understanding of how to teach a particular discipline with an evolving understanding how people learn that discipline. At its center, DBER has an overarching goal of improving the teaching and learning of a discipline by focusing on understanding the underlying mental mechanisms learners use as they develop expertise. Geoscience Education Research, or GER, is a young but rapidly advancing field which is poised to make important contributions to the teaching and learning of earth and space science. Nascent geoscience education researchers could accelerate their community's progress by learning some of the lessons from the more mature field of Physics Education Research, PER. For the past three decades, the PER community has been on the cutting edge of DBER. PER started purely as an effort among traditionally trained physicists to overcome students' tenaciously held misconceptions about force, motion, and electricity. Over the years, PER has wrestled with the extent to which they included the faculty from the College of Education, the value placed on interpretive and qualitative research methods, the most appropriate involvement of professional societies, the nature of its PhD programs in the College of Science, and how to best disseminate the results of PER to the wider physics teaching community. Decades later, as a more fully mature field, PER still struggles with some of these aspects, but has learned important lessons in how its community progresses and evolves to be successful, valuable, and pertinent.

Theoretical and methodological elements for integrating ethics as a foundation into the education of professional and design disciplines.

Science.gov (United States)

d'Anjou, Philippe

2004-04-01

The paper addresses the integration of ethics into professional education related to the disciplines responsible for the conception and creation of the artificial (artefactual or technology). The ontological-epistemological paradigm of those disciplines is understood within the frame of the sciences of the artificial as established by Herbert Simon (1969). According to that paradigm, those sciences include disciplines not only related to the production of artefacts (technology), such as engineering, architecture, industrial design, etc, but also disciplines related to devised courses of action aimed at changing existing situations into preferred ones, like medicine, law, education, etc. They are centered on intentional action and at their core is the activity of design, which is their common foundation and attitude, or their common culture. The science of design becomes the broader foundational discipline for any professions engaged in the intentional transformation of the world. The main distinction between design disciplines and scientific ones rests on the object-project dichotomy. Indeed, contrary to Science that sees the world as an object to be observed, Design sees the world as a project and acts upon the world through projects, which are grounded in intentions, ends, and values. Design disciplines are meant to transform the world, or part of it, and are teleological. Being so, they are embodied in an act that is ethical and their ontology-epistemology must be addressed also through practical reason to resituate all professional disciplines according to their involved nature. The paper introduces theoretical, methodological, and ethical elements to establish a model that integrates ethics into the education of the professional disciplines, design-based disciplines, responsible for the creation of the artificial, artefactual or technological, world. The model is articulated around the notions of ethical engagement and responsibility through the act of design

Laplacian Estrada and normalized Laplacian Estrada indices of evolving graphs.

Science.gov (United States)

Shang, Yilun

2015-01-01

Large-scale time-evolving networks have been generated by many natural and technological applications, posing challenges for computation and modeling. Thus, it is of theoretical and practical significance to probe mathematical tools tailored for evolving networks. In this paper, on top of the dynamic Estrada index, we study the dynamic Laplacian Estrada index and the dynamic normalized Laplacian Estrada index of evolving graphs. Using linear algebra techniques, we established general upper and lower bounds for these graph-spectrum-based invariants through a couple of intuitive graph-theoretic measures, including the number of vertices or edges. Synthetic random evolving small-world networks are employed to show the relevance of the proposed dynamic Estrada indices. It is found that neither the static snapshot graphs nor the aggregated graph can approximate the evolving graph itself, indicating the fundamental difference between the static and dynamic Estrada indices.

Human rights values or cultural values? Pursuing values to maintain positive discipline in multicultural schools

Directory of Open Access Journals (Sweden)

Petro du Preez

2010-01-01

Full Text Available Discussions on discipline in education often accentuate corporal punishment or measures to infuse moral fibre. In addition, many authors argue that inculcating a particular value system can promote discipline in schools. This could however be profoundly problematic in the light of the Constitution. We argue that positive discipline in multicultural school environments needs to be based in part on human rights values that are neither solely universally interpreted nor particularistically interpreted. We report on the data generated at a research workshop held as the final dissemination process of a four-year international research project entitled "Understanding human rights through different belief systems: intercultural and interreligious dialogue". Dialogue was chosen as a form of data gathering since it is more spontaneous than conventional questioning techniques and can thus generate more naturally occurring data to strengthen the outcomes of the project. It appears that some teachers believe discipline can only be maintained through the elevation of cultural values (particularism. We argue that schools should start negotiating, at the most basic level, the values, including emancipatory, human rights values, and cultural values, which could underpin positive discipline in multicultural schools. Drawing solely on cultural values is not only unlikely to solve the problem of discipline, but could also undermine the efforts to transform our diverse, democratic society.

Austerity, Discipline and Social Security

Full Text Available One of the manifestations of the global crisis of financial capitalism and the policies arising from it was the imposition of austerity measures, which not only resulted in privatization of the commons and general expropriation of the people, but also managed to introduce new mechanisms of discipline and punishment. Debt, being the fundament of relations in society, forced itself into the system of social security: new legislation, regulating welfare benefits, has now shifted to a method for the criminalization of poverty, deepening class differences and transforming social workers (and the system of social security as a whole into a moralizing, bureaucratic machine for disciplining the population. The new legislation also shows a lack of reflection on the changes that need to be made to the welfare state in order to create social services that meet the needs and desires of individuals. Instead of improvements that provide decent living conditions and a new system of social rights (to deal with the problems resulting from precarious working conditions, people are faced with depersonalization, humiliation and increased hate speech and other fascist practices. The effect of austerity measures on the social security system does not end with the devastation of service users’ lives and their communities, which are slowly becoming exhausted, individualized and devoid of solidarity. It also means a big step backwards for the core ethics and principles of social work. Social workers are increasingly alienated from their clients and the communities they live in. They function more in the service of the government and its policies rather than as advocates of people’s rights.

Some bacteria have evolved resistance to nearly every known class of antibiotic, creating an urgent need for new ones that work by different mechanisms. However, there has been no simple way to determine how new antibiotics work. We have developed a unique method that provides a shortcut for understanding how antibiotics kill bacteria. This method can be used to sift through compounds to rapidly identify and characterize antibiotics that work against multidrug-resistant pathogens.

[At the limits of discipline].

According to Foucault, in medicine, the paradigm of discipline has outweighed the paradigm of sovereignty for over a hundred years now. It has become clear, however, that within the field of psychiatry, particularly in psychoanalytic and psychotherapeutic research, an interchangeable corpus of knowledge is not sufficient for the treatment of patients. Moreover, it is often the changing relationship between doctor and patient which seems to be crucial to the process and outcome of the treatment. Every treatment-relationship must be understood as a zone of transference. Psychoanalytic research on transference, its potential and pitfalls, therefore, has to be more integrated into the research of psychic disorders.

Whole genome duplication affects evolvability of flowering time in an autotetraploid plant.

Directory of Open Access Journals (Sweden)

Sara L Martin

Full Text Available Whole genome duplications have occurred recurrently throughout the evolutionary history of eukaryotes. The resulting genetic and phenotypic changes can influence physiological and ecological responses to the environment; however, the impact of genome copy number on evolvability has rarely been examined experimentally. Here, we evaluate the effect of genome duplication on the ability to respond to selection for early flowering time in lines drawn from naturally occurring diploid and autotetraploid populations of the plant Chamerion angustifolium (fireweed. We contrast this with the result of four generations of selection on synthesized neoautotetraploids, whose genic variability is similar to diploids but genome copy number is similar to autotetraploids. In addition, we examine correlated responses to selection in all three groups. Diploid and both extant tetraploid and neoautotetraploid lines responded to selection with significant reductions in time to flowering. Evolvability, measured as realized heritability, was significantly lower in extant tetraploids (^b(T =  0.31 than diploids (^b(T =  0.40. Neotetraploids exhibited the highest evolutionary response (^b(T  =  0.55. The rapid shift in flowering time in neotetraploids was associated with an increase in phenotypic variability across generations, but not with change in genome size or phenotypic correlations among traits. Our results suggest that whole genome duplications, without hybridization, may initially alter evolutionary rate, and that the dynamic nature of neoautopolyploids may contribute to the prevalence of polyploidy throughout eukaryotes.

Niu, Hua; Liu, Li; Wang, Meifang

2018-05-01

The present study examined the intergenerational transmission of harsh discipline (psychological aggression and corporal punishment) and the moderating effects of parenting stress and parent gender in Chinese societies. Utilizing a sample of 634 Chinese father-mother dyads with preschoolers, findings revealed that both mothers' and fathers' harsh discipline were transmitted across generations and the strength of transmission varied by the severity of harsh discipline and the parent gender. For both mothers and fathers, high parenting stress intensified the intergenerational transmission of psychological aggression and corporal punishment, whereas low parenting stress weakened the transmission of psychological aggression and even disrupted the transmission of corporal punishment. Moreover, the moderating effects of parenting stress on the transmission were stronger for mothers than for fathers. Findings from the present study highlight the importance of considering how the proximal environmental factors (such as parenting stress) may influence the intergenerational transmission of harsh discipline.

Laplacian Estrada and normalized Laplacian Estrada indices of evolving graphs.

Directory of Open Access Journals (Sweden)

Yilun Shang

Full Text Available Large-scale time-evolving networks have been generated by many natural and technological applications, posing challenges for computation and modeling. Thus, it is of theoretical and practical significance to probe mathematical tools tailored for evolving networks. In this paper, on top of the dynamic Estrada index, we study the dynamic Laplacian Estrada index and the dynamic normalized Laplacian Estrada index of evolving graphs. Using linear algebra techniques, we established general upper and lower bounds for these graph-spectrum-based invariants through a couple of intuitive graph-theoretic measures, including the number of vertices or edges. Synthetic random evolving small-world networks are employed to show the relevance of the proposed dynamic Estrada indices. It is found that neither the static snapshot graphs nor the aggregated graph can approximate the evolving graph itself, indicating the fundamental difference between the static and dynamic Estrada indices.

Full Text Available This study explored the aspirations of undergraduate engineering students in regard to helping others, examining potential differences between disciplines and institutions. Over 1900 undergraduate students from 17 U.S. universities responded to a survey in spring 2014. In open-ended responses, 15.5% of the students included some form of helping people and/or the world as one of the factors that motivated them to select their engineering major; for 6.7% of the students this was the primary or only motivating factor listed. Helping as a motivation was not equally prevalent among different engineering disciplines, being much more common among students majoring in biomedical, environmental, materials, and civil and less common in computer and aerospace. Different disciplines also varied in the priority for helping people relative to other future job factors - highest in chemical/biological, moderate in civil and related majors, and lowest among electrical/computer and mechanical. Institutional differences were found in the extent to which students indicated an importance that their career would help people and the extent to which an ability to help others was a central message in their major. The results indicate the percentages of engineering students who are most likely to embrace humanitarian engineering; fostering these aspirations in students could help with attraction and retention.

Physics and Mathematics as Interwoven Disciplines in Science Education

Galili, Igal

2018-03-01

The relationship between physics and mathematics is reviewed upgrading the common in physics classes' perspective of mathematics as a toolkit for physics. The nature of the physics-mathematics relationship is considered along a certain historical path. The triadic hierarchical structure of discipline-culture helps to identify different ways in which mathematics is used in physics and to appreciate its contribution, to recognize the difference between mathematics and physics as disciplines in approaches, values, methods, and forms. We mentioned certain forms of mathematical knowledge important for physics but often missing in school curricula. The geometrical mode of codification of mathematical knowledge is compared with the analytical one in context of teaching school physics and mathematics; their complementarity is exemplified. Teaching may adopt the examples facilitating the claims of the study to reach science literacy and meaningful learning.

Disciplining Bioethics: Towards a Standard of Methodological Rigor in Bioethics Research

Science.gov (United States)

Adler, Daniel; Shaul, Randi Zlotnik

2012-01-01

Contemporary bioethics research is often described as multi- or interdisciplinary. Disciplines are characterized, in part, by their methods. Thus, when bioethics research draws on a variety of methods, it crosses disciplinary boundaries. Yet each discipline has its own standard of rigor—so when multiple disciplinary perspectives are considered, what constitutes rigor? This question has received inadequate attention, as there is considerable disagreement regarding the disciplinary status of bioethics. This disagreement has presented five challenges to bioethics research. Addressing them requires consideration of the main types of cross-disciplinary research, and consideration of proposals aiming to ensure rigor in bioethics research. PMID:22686634

Realism and Relativism in the Development of Nursing as a Discipline.

Hirani, Shela Akbar Ali; Richter, Solina; Salami, Bukola Oladunni

In today's era of nursing, the role of a unique disciplinary knowledge that is grounded in philosophy is essential to inform nursing practice, fill knowledge gaps, improve the quality of nursing education, and guide the theoretical development of nursing. Realism and relativism have contributed to the development of the nursing discipline by providing the basis of evidence-based nursing practice, nursing research, nursing education, and theoretical construction. This article explores the role of realism and relativism in the development of the discipline of nursing and presents their contributions to the work of nurse clinicians, nurse researchers, nurse educators, and nurse theorists.

Evolvable mathematical models: A new artificial Intelligence paradigm

Science.gov (United States)

Grouchy, Paul

We develop a novel Artificial Intelligence paradigm to generate autonomously artificial agents as mathematical models of behaviour. Agent/environment inputs are mapped to agent outputs via equation trees which are evolved in a manner similar to Symbolic Regression in Genetic Programming. Equations are comprised of only the four basic mathematical operators, addition, subtraction, multiplication and division, as well as input and output variables and constants. From these operations, equations can be constructed that approximate any analytic function. These Evolvable Mathematical Models (EMMs) are tested and compared to their Artificial Neural Network (ANN) counterparts on two benchmarking tasks: the double-pole balancing without velocity information benchmark and the challenging discrete Double-T Maze experiments with homing. The results from these experiments show that EMMs are capable of solving tasks typically solved by ANNs, and that they have the ability to produce agents that demonstrate learning behaviours. To further explore the capabilities of EMMs, as well as to investigate the evolutionary origins of communication, we develop NoiseWorld, an Artificial Life simulation in which interagent communication emerges and evolves from initially noncommunicating EMM-based agents. Agents develop the capability to transmit their x and y position information over a one-dimensional channel via a complex, dialogue-based communication scheme. These evolved communication schemes are analyzed and their evolutionary trajectories examined, yielding significant insight into the emergence and subsequent evolution of cooperative communication. Evolved agents from NoiseWorld are successfully transferred onto physical robots, demonstrating the transferability of EMM-based AIs from simulation into physical reality.

The benefits of physical activity (PA) in preventing abdominal obesity are well recognized, but the role of different sport disciplines remains open. We aimed, therefore, to investigate how participation in different sport disciplines, and the number and types of sports engaged in are associated with waist circumference (WC) in young adulthood. This population-based cohort study comprised 4027 Finnish twin individuals (1874 men), with a mean age of 34 y (32-37), who answered a survey, including self-measured WC. We extracted the number and identified the types (aerobic, power, and mixed) of the different sport disciplines respondents reported participating in. The number of sport disciplines participated in was inversely associated with WC, the linear decrease averaging 1.38 cm (95% CI 1.10-1.65) per each additional sport discipline. The result persisted after adjustment for the main covariates, such as volume of PA and diet quality. Among dizygotic twin pairs discordant for sports participation (0-2 vs. 5 or more disciplines), the mean within-pair difference in WC was 4.8 cm (95% CI 0.4-9.1) for men and 11.2 cm (95% CI 4.4-18.0) for women; among discordant monozygotic pairs, no differences were observed. In men, all three types of sports were individually associated with smaller WC, while in women, only mixed and power sports showed this association. Participation in several sport disciplines and sport types was associated with smaller WC among young adults in their mid-30s. Shared genetic background may explain some of the associations.

Emergency medicine is a new academic discipline, as well as a recent independent clinical specialization with the specific principles of practice, education and research. It is also a very important segment of the overall health care and health system. Emergency medicine as a distinct specialty was introduced in the U.S. in 1970. Ten years later and relatively quickly emergency medicine was introduced in the health system in Bosnia and Herzegovina as a specialty with a special education program for specialist and a final exam. Compare the development of emergency medicine in Bosnia and Herzegovina with the trends of development of this discipline in the world as a specialization and an academic discipline. Identify specific problems and possible solutions and learn lessons from other countries. Reviewed are the literature data on the development of emergency medicine in the world, programs of undergraduate and postgraduate teaching, the organizational scheme of emergency centers and residency. This is then compared with data of the current status of emergency medicine as an academic discipline and a recognized specialization, in Bosnia and Herzegovina. There are substantial differences in the development of emergency medicine in the United States, European Union and Bosnia and Herzegovina. Although Bosnia and Herzegovina relatively early recognized specialty of emergency medicine in academia, it failed to mach the academic progress with the practical implementation. A&E departments in the Community Health Centers failed to meet the desired objectives even though they were led by specialists in emergency medicine. The main reason being the lack of space and equipment as well as staff needed to meet set standards of good clinical practice, education and research. Furthermore the Curriculum of undergraduate education and specialization does not match modern concept of educational programs that meet the principles set out in emergency medicine and learning through

Human-Centered Design as an Integrating Discipline

Directory of Open Access Journals (Sweden)

Guy André Boy

2017-02-01

Full Text Available What is research today? Good research has to be indexed within appropriate mechanisms to be visible, considered and finally useful. These mechanisms are based on quantitative research methods and codes that are often very academic. Consequently, they impose rigorous constraints on the way results should be obtained and presented. In addition, everything people learn in academia needs to be graded. This leads to standard packaging of what should be learned and results in making people executants and not creators nor inventors. In other words, this academic standardization precludes freedom for innovation. This paper proposes Human-Centered Design (HCD as a solution to override these limitations and roadblocks. HCD involves expertise, experience, participation, modeling and simulation, complexity analysis and qualitative research. What is education today? Education is organized in silos with little attempt to integrate individual academic disciplines. Large system integration is almost never learned in engineering schools, and Human- Systems Integration (HSI even less. Instead, real-life problemsolving requires integration skills. What is design research? We often hear that design has nothing to do with research, and conversely. Putting design and research together, as complementary disciplines, contributes to combine creativity, rigorous demonstration and validation. This is somehow what HCD is about.

Parenting stress and harsh discipline in China: The moderating roles of marital satisfaction and parent gender.

Liu, Li; Wang, Meifang

2015-05-01

This research examined the relationships between parents' parenting stress and their harsh discipline (psychological aggression and corporal punishment) and the moderating effects of marital satisfaction and parent gender in Chinese societies. Using a sample of 639 Chinese father-mother dyads with preschoolers, findings revealed that both mothers' and fathers' parenting stress were directly associated with their harsh discipline. Mothers' marital satisfaction attenuated the association between their parenting stress and harsh discipline. However, fathers' marital satisfaction did not moderate the association between their parenting stress and harsh discipline. Findings from the current study highlight the importance of considering how the dyadic marital relationship factors may interact with individuals' parenting stress to influence both maternal and paternal disciplinary behaviors.

This study used cross-lagged modeling to examine reciprocal relations between maternal and paternal harsh verbal discipline and adolescents' conduct problems and depressive symptoms. Data were from a sample of 976 two-parent families and their children (51% males; 54% European American, 40% African American). Mothers' and fathers' harsh verbal discipline at age 13 predicted an increase in adolescent conduct problems and depressive symptoms between ages 13 and 14. A child effect was also present, with adolescent misconduct at age 13 predicting increases in mothers' and fathers' harsh verbal discipline between ages 13 and 14. Furthermore, maternal and paternal warmth did not moderate the longitudinal associations between mothers' and fathers' use of harsh verbal discipline and adolescent conduct problems and depressive symptoms.

To examine evidence of the continuity in abusive discipline across two generations (G1 and G2) and the role of safe, stable, and nurturing relationships (SSNRs) as protective factors. Data are from the Lehigh Longitudinal Study, a prospective investigation of the causes and consequences child maltreatment that began in the 1970s with a sample of 457 children and their parents. Data were most recently collected in 2008-2010 from 80% of the original child sample (N = 357) when they were adults age 36 years on average. Of those assessed as adults, 268 participants (G2s) were parenting children and thus comprise the analysis sample. Analyses examined the association between harsh physical discipline practices by G1 parents and G2's reports of similarly severe discipline practices used in parenting their own children. Analyses also investigated the direct and interactive (protective) effects of SSNR variables that pertain to the care, warmth, and support children received from their mothers, fathers, and siblings over their lifetimes. A measure of an adult partner's warmth and support was also included. A case-level examination of G2 harsh discipliners was included to investigate other forms of past and more recent forms of abuse exposure. Results show a significant predictive association between physical discipline by G1 and G2 parents (β = .30; p disciplined as a child was inversely related to reports of having had a caring relationship with one's mother (r = -.25; p discipline by G2s (β = -.24; p discipline on G2 discipline. A case-level examination of the abusive histories of G2 harsh discipliners found they had in some instances been exposed to physical and emotional abuse by multiple caregivers and by adult partners. There is continuity in physical disciplining over two generations. SSNRs measured in this study did not mediate or moderate the effect of G1 on G2 harsh physical discipline, although care and support from fathers was inversely related to the

Hence, midwifery must be theory based because theories serve as a broad framework for practice and may also articulate the goals of a profession and core values. In this paper, an evolving theory on the empowerment of childbearing women is introduced, where the midwife's professionalism is central. The theory is synthesized from nine datasets and scholarly work, and then more than three hundred studies were reviewed for clarification and confirmation. According to the theory, the midwife's professionalism is constructed from five main aspects: The professional midwife cares for the childbearing woman and her family. This caring within the professional domain is seen as the core of midwifery. The professional midwife is professionally competent. This professional competence must always have primacy for the sake of safety of woman and child. The professional midwife has professional wisdom and knows how to apply it. Professional wisdom is a new concept used to denote the interplay of knowledge and experience. The professional midwife has interpersonal competence, is capable of empowering communication and positive partnership with the woman and her family. The professional midwife develops herself both personally and professionally, which is the prerequisite for true professionalism. This evolving theory must be regularly reconstructed in the light of current knowledge within midwifery. It is an attempt to identify and articulate the processes and components of the art and science of midwifery practice in an endeavour of continuing the discipline's development by assisting in the understanding and practice of creating further theoretical discourse, processes and products for midwifery practice. The theory has implications for midwifery education and practice. �

For diverse scientific disciplines to interoperate they must be able to exchange information based on a shared understanding. To capture this shared understanding, we have developed a knowledge representation framework that leverages ISO level reference models for metadata registries and digital archives. This framework provides multi-level governance, evolves independent of the implementation technologies, and promotes agile development, namely adaptive planning, evolutionary development, early delivery, continuous improvement, and rapid and flexible response to change. The knowledge representation is captured in an ontology through a process of knowledge acquisition. Discipline experts in the role of stewards at the common, discipline, and project levels work to design and populate the ontology model. The result is a formal and consistent knowledge base that provides requirements for data representation, integrity, provenance, context, identification, and relationship. The contents of the knowledge base are translated and written to files in suitable formats to configure system software and services, provide user documentation, validate input, and support data analytics. This presentation will provide an overview of the framework, present a use case that has been adopted by an entire science discipline at the international level, and share some important lessons learned.

Yock, Paul G; Brinton, Todd J; Zenios, Stefanos A

2011-07-20

Recently, universities in the United States and abroad have developed dedicated educational programs in life science technology innovation. Here, we discuss the two major streams of educational theory and practice that have informed these programs: design thinking and entrepreneurship education. We make the case that the process of innovation for new medical technologies (medtech) is different from that for biopharmaceuticals and outline the challenges and opportunities associated with developing a discipline of medtech innovation.

CMIP6 Data Citation of Evolving Data

Martina Stockhause

2017-06-01

Full Text Available Data citations have become widely accepted. Technical infrastructures as well as principles and recommendations for data citation are in place but best practices or guidelines for their implementation are not yet available. On the other hand, the scientific climate community requests early citations on evolving data for credit, e.g. for CMIP6 (Coupled Model Intercomparison Project Phase 6. The data citation concept for CMIP6 is presented. The main challenges lie in limited resources, a strict project timeline and the dependency on changes of the data dissemination infrastructure ESGF (Earth System Grid Federation to meet the data citation requirements. Therefore a pragmatic, flexible and extendible approach for the CMIP6 data citation service was developed, consisting of a citation for the full evolving data superset and a data cart approach for citing the concrete used data subset. This two citation approach can be implemented according to the RDA recommendations for evolving data. Because of resource constraints and missing project policies, the implementation of the second part of the citation concept is postponed to CMIP7.

Neurogenomics and the role of a large mutational target on rapid behavioral change.

Science.gov (United States)

Stanley, Craig E; Kulathinal, Rob J

2016-11-08

Behavior, while complex and dynamic, is among the most diverse, derived, and rapidly evolving traits in animals. The highly labile nature of heritable behavioral change is observed in such evolutionary phenomena as the emergence of converged behaviors in domesticated animals, the rapid evolution of preferences, and the routine development of ethological isolation between diverging populations and species. In fact, it is believed that nervous system development and its potential to evolve a seemingly infinite array of behavioral innovations played a major role in the successful diversification of metazoans, including our own human lineage. However, unlike other rapidly evolving functional systems such as sperm-egg interactions and immune defense, the genetic basis of rapid behavioral change remains elusive. Here we propose that the rapid divergence and widespread novelty of innate and adaptive behavior is primarily a function of its genomic architecture. Specifically, we hypothesize that the broad diversity of behavioral phenotypes present at micro- and macroevolutionary scales is promoted by a disproportionately large mutational target of neurogenic genes. We present evidence that these large neuro-behavioral targets are significant and ubiquitous in animal genomes and suggest that behavior's novelty and rapid emergence are driven by a number of factors including more selection on a larger pool of variants, a greater role of phenotypic plasticity, and/or unique molecular features present in large genes. We briefly discuss the origins of these large neurogenic genes, as they relate to the remarkable diversity of metazoan behaviors, and highlight key consequences on both behavioral traits and neurogenic disease across, respectively, evolutionary and ontogenetic time scales. Current approaches to studying the genetic mechanisms underlying rapid phenotypic change primarily focus on identifying signatures of Darwinian selection in protein-coding regions. In contrast

Thungon, Phurpa Dema; Kakoti, Ankana; Ngashangva, Lightson; Goswami, Pranab

2017-11-15

Development of portable, reliable, sensitive, simple, and inexpensive detection system for alcohol has been an instinctive demand not only in traditional brewing, pharmaceutical, food and clinical industries but also in rapidly growing alcohol based fuel industries. Highly sensitive, selective, and reliable alcohol detections are currently amenable typically through the sophisticated instrument based analyses confined mostly to the state-of-art analytical laboratory facilities. With the growing demand of rapid and reliable alcohol detection systems, an all-round attempt has been made over the past decade encompassing various disciplines from basic and engineering sciences. Of late, the research for developing small-scale portable alcohol detection system has been accelerated with the advent of emerging miniaturization techniques, advanced materials and sensing platforms such as lab-on-chip, lab-on-CD, lab-on-paper etc. With these new inter-disciplinary approaches along with the support from the parallel knowledge growth on rapid detection systems being pursued for various targets, the progress on translating the proof-of-concepts to commercially viable and environment friendly portable alcohol detection systems is gaining pace. Here, we summarize the progress made over the years on the alcohol detection systems, with a focus on recent advancement towards developing portable, simple and efficient alcohol sensors.

Examining classroom influences on student perceptions of school climate: the role of classroom management and exclusionary discipline strategies.

Science.gov (United States)

Mitchell, Mary M; Bradshaw, Catherine P

2013-10-01

There is growing emphasis on the use of positive behavior supports rather than exclusionary discipline strategies to promote a positive classroom environment. Yet, there has been limited research examining the association between these two different approaches to classroom management and students' perceptions of school climate. Data from 1902 students within 93 classrooms that were nested within 37 elementary schools were examined using multilevel structural equation modeling procedures to investigate the association between two different classroom management strategies (i.e., exclusionary discipline strategies and the use of positive behavior supports) and student ratings of school climate (i.e., fairness, order and discipline, student-teacher relationship, and academic motivation). The analyses indicated that greater use of exclusionary discipline strategies was associated with lower order and discipline scores, whereas greater use of classroom-based positive behavior supports was associated with higher scores on order and discipline, fairness, and student-teacher relationship. These findings suggest that pre-service training and professional development activities should promote teachers' use of positive behavior support strategies and encourage reduced reliance on exclusionary discipline strategies in order to enhance the school climate and conditions for learning.

Orthogonally Evolved AI to Improve Difficulty Adjustment in Video Games

DEFF Research Database (Denmark)

Hintze, Arend; Olson, Randal; Lehman, Joel Anthony

2016-01-01

Computer games are most engaging when their difficulty is well matched to the player's ability, thereby providing an experience in which the player is neither overwhelmed nor bored. In games where the player interacts with computer-controlled opponents, the difficulty of the game can be adjusted...... not only by changing the distribution of opponents or game resources, but also through modifying the skill of the opponents. Applying evolutionary algorithms to evolve the artificial intelligence that controls opponent agents is one established method for adjusting opponent difficulty. Less-evolved agents...... (i.e. agents subject to fewer generations of evolution) make for easier opponents, while highly-evolved agents are more challenging to overcome. In this publication we test a new approach for difficulty adjustment in games: orthogonally evolved AI, where the player receives support from collaborating...

The Big Data Tools Impact on Development of Simulation-Concerned Academic Disciplines

Directory of Open Access Journals (Sweden)

A. A. Sukhobokov

2015-01-01

Full Text Available The article gives a definition of Big Data on the basis of 5V (Volume, Variety, Velocity, Veracity, Value as well as shows examples of tasks that require using Big Data tools in a diversity of areas, namely: health, education, financial services, industry, agriculture, logistics, retail, information technology, telecommunications and others. An overview of Big Data tools is delivered, including open source products, IBM Bluemix and SAP HANA platforms. Examples of architecture of corporate data processing and management systems using Big Data tools are shown for big Internet companies and for enterprises in traditional industries. Within the overview, a classification of Big Data tools is proposed that fills gaps of previously developed similar classifications. The new classification contains 19 classes and allows embracing several hundreds of existing and emerging products.The uprise and use of Big Data tools, in addition to solving practical problems, affects the development of scientific disciplines concerning the simulation of technical, natural or socioeconomic systems and the solution of practical problems based on developed models. New schools arise in these disciplines. These new schools decide peculiar to each discipline tasks, but for systems with a much bigger number of internal elements and connections between them. Characteristics of the problems to be solved under new schools, not always meet the criteria for Big Data. It is suggested to identify the Big Data as a part of the theory of sorting and searching algorithms. In other disciplines the new schools are called by analogy with Big Data: Big Calculation in numerical methods, Big Simulation in imitational modeling, Big Management in the management of socio-economic systems, Big Optimal Control in the optimal control theory. The paper shows examples of tasks and methods to be developed within new schools. The educed tendency is not limited to the considered disciplines: there are

Bridging different perspectives of the physiological and mathematical disciplines.

Batzel, Jerry Joseph; Hinghofer-Szalkay, Helmut; Kappel, Franz; Schneditz, Daniel; Kenner, Thomas; Goswami, Nandu

2012-12-01

The goal of this report is to discuss educational approaches for bridging the different perspectives of the physiological and mathematical disciplines. These approaches can enhance the learning experience for physiology, medical, and mathematics students and simultaneously act to stimulate mathematical/physiological/clinical interdisciplinary research. While physiology education incorporates mathematics, via equations and formulas, it does not typically provide a foundation for interdisciplinary research linking mathematics and physiology. Here, we provide insights and ideas derived from interdisciplinary seminars involving mathematicians and physiologists that have been conducted over the last decade. The approaches described here can be used as templates for giving physiology and medical students insights into how sophisticated tools from mathematics can be applied and how the disciplines of mathematics and physiology can be integrated in research, thereby fostering a foundation for interdisciplinary collaboration. These templates are equally applicable to linking mathematical methods with other life and health sciences in the educational process.

Drawing Women In: Engaging in Science and Engineering Disciplines

Science.gov (United States)

Greene, Senta

2013-03-01

Recent data on the participation of women in the scientific, technological, engineering, and mathematical (STEM) disciplines shows a landscape that is somewhat different from our expectations in the past. For example, women who earn bachelors' degrees in physics go on to earn PhDs, be hired to faculty positions, and achieve promotions at the same rate as their male counterparts. However, such gains do not foretell equal participation of women in physics since, although girls make up about half of high school physics classes, the fraction of bachelor's degrees earned by women has been flat at around 20% for about a decade. This remains true even with significantly increased awareness of the need to attract more women to STEM fields and despite various interventions to attract and retain talented women. This talk will present an overview of data on women's participation in STEM disciplines, provide possible explanations for the continued failure to attract women to some STEM fields, and give a brief description of some current interventions.

More rapid climate change promotes evolutionary rescue through selection for increased dispersal distance.

Science.gov (United States)

Boeye, Jeroen; Travis, Justin M J; Stoks, Robby; Bonte, Dries

2013-02-01

Species can either adapt to new conditions induced by climate change or shift their range in an attempt to track optimal environmental conditions. During current range shifts, species are simultaneously confronted with a second major anthropogenic disturbance, landscape fragmentation. Using individual-based models with a shifting climate window, we examine the effect of different rates of climate change on the evolution of dispersal distances through changes in the genetically determined dispersal kernel. Our results demonstrate that the rate of climate change is positively correlated to the evolved dispersal distances although too fast climate change causes the population to crash. When faced with realistic rates of climate change, greater dispersal distances evolve than those required for the population to keep track of the climate, thereby maximizing population size. Importantly, the greater dispersal distances that evolve when climate change is more rapid, induce evolutionary rescue by facilitating the population in crossing large gaps in the landscape. This could ensure population persistence in case of range shifting in fragmented landscapes. Furthermore, we highlight problems in using invasion speed as a proxy for potential range shifting abilities under climate change.

Infectious diseases now threaten wildlife populations worldwide but population recovery following local extinction has rarely been observed. In such a case, do resistant individuals recolonize from a central remnant population, or do they spread from small, perhaps overlooked, populations of resistant individuals? Introduced avian malaria (Plasmodium relictum) has devastated low-elevation populations of native birds in Hawaii, but at least one species (Hawaii amakihi, Hemignathus virens) that was greatly reduced at elevations below about 1000 m tolerates malaria and has initiated a remarkable and rapid recovery. We assessed mitochondrial and nuclear DNA markers from amakihi and two other Hawaiian honeycreepers, apapane (Himatione sanguinea) and iiwi (Vestiaria coccinea), at nine primary study sites from 2001 to 2003 to determine the source of re-establishing birds. In addition, we obtained sequences from tissue from amakihi museum study skins (1898 and 1948-49) to assess temporal changes in allele distributions. We found that amakihi in lowland areas are, and have historically been, differentiated from birds at high elevations and had unique alleles retained through time; that is, their genetic signature was not a subset of the genetic variation at higher elevations. We suggest that high disease pressure rapidly selected for resistance to malaria at low elevation, leaving small pockets of resistant birds, and this resistance spread outward from the scattered remnant populations. Low-elevation amakihi are currently isolated from higher elevations (> 1000 m) where disease emergence and transmission rates appear to vary seasonally and annually. In contrast to results from amakihi, no genetic differentiation between elevations was found in apapane and iiwi, indicating that slight variation in genetic or life-history attributes can determine disease resistance and population recovery. Determining the conditions that allow for the development of resistance to disease is

Challenge: A Multidisciplinary Degree Program in Bioinformatics

Directory of Open Access Journals (Sweden)

Mudasser Fraz Wyne

2006-06-01

Full Text Available Bioinformatics is a new field that is poorly served by any of the traditional science programs in Biology, Computer science or Biochemistry. Known to be a rapidly evolving discipline, Bioinformatics has emerged from experimental molecular biology and biochemistry as well as from the artificial intelligence, database, pattern recognition, and algorithms disciplines of computer science. While institutions are responding to this increased demand by establishing graduate programs in bioinformatics, entrance barriers for these programs are high, largely due to the significant prerequisite knowledge which is required, both in the fields of biochemistry and computer science. Although many schools currently have or are proposing graduate programs in bioinformatics, few are actually developing new undergraduate programs. In this paper I explore the blend of a multidisciplinary approach, discuss the response of academia and highlight challenges faced by this emerging field.

Frustration influences impact of history and disciplinary attitudes on physical discipline decision making.

Science.gov (United States)

Russa, Mary B; Rodriguez, Christina M; Silvia, Paul J

2014-01-01

Although intergenerational patterns of punitive physical punishment garner considerable research attention, the mechanisms by which historical, cognitive, and contextual factors interplay to influence disciplinary responding remains poorly understood. Disciplinary attitudes have been shown to mediate the association between disciplinary history and disciplinary responding. The present study investigated whether frustration influences these mediation effects. Half of a sample of 330 undergraduates was randomly assigned to frustration induction. Structural equation modeling confirmed that, for participants in the frustration condition, the relation between disciplinary history and physical discipline decision-making was fully mediated by attitudes approving physical discipline. In contrast, for respondents in the no-frustration condition, the pathway from disciplinary history to discipline decision-making was only partially mediated by attitudes. Under conditions of frustration, attitudes may become a more central means by which personal disciplinary history is associated with disciplinary decision-making. © 2013 Wiley Periodicals, Inc.

Maternal discipline of children with Asperger Syndrome and nonverbal learning disorders.

Science.gov (United States)

Little, Liza

2002-01-01

This study investigated how often mothers of children with Asperger Syndrome and nonverbal learning disorders reported using either psychological aggression (shouting, cursing, name calling) or corporal punishment (spanking, hitting) when disciplining their children, and also examined the correlates of these methods of discipline. A descriptive study of 41l mothers with children between ages 4 and 17 years. Mothers were recruited by placing an invitation on two national Web sites; one for parents of children with Asperger syndrome and one for parents of children with nonverbal learning disabilities. An anonymous, mailed survey was used and a 70% response rate was obtained. The Conflict Tactics Scale-Child Form was used to measure psychological aggression and corporal punishment. Univariate analyses were used to describe the child and maternal characteristics and maternal rates of discipline. The correlates of maternal discipline were measured using bivariate analyses. The overall reported use of any corporal punishment (slaps on the hand, arm, and leg; hitting on the buttocks with a belt or brush; spanking on the buttocks with a hand; pinching and shaking) during the past year was 58%. The yearly use of any psychological aggression (screaming and yelling, cursing, threatening to hit or spank, threatening to kick out or send away, calling the child "dumb" or "lazy") was 95%. Spanking declined with increasing age of the child and the mother. Mothers who used psychological aggression were more likely to use corporal punishment with their child. Informed nurses working with these populations can use the results of this study to help address the stresses felt by these mothers, and to teach alternative strategies of coping to mothers who are in danger of using psychological aggression and corporal punishment.

Computational Genetic Regulatory Networks Evolvable, Self-organizing Systems

CERN Document Server

Knabe, Johannes F

2013-01-01

Genetic Regulatory Networks (GRNs) in biological organisms are primary engines for cells to enact their engagements with environments, via incessant, continually active coupling. In differentiated multicellular organisms, tremendous complexity has arisen in the course of evolution of life on earth. Engineering and science have so far achieved no working system that can compare with this complexity, depth and scope of organization. Abstracting the dynamics of genetic regulatory control to a computational framework in which artificial GRNs in artificial simulated cells differentiate while connected in a changing topology, it is possible to apply Darwinian evolution in silico to study the capacity of such developmental/differentiated GRNs to evolve. In this volume an evolutionary GRN paradigm is investigated for its evolvability and robustness in models of biological clocks, in simple differentiated multicellularity, and in evolving artificial developing 'organisms' which grow and express an ontogeny starting fr...

Adaptive inferential sensors based on evolving fuzzy models.

Science.gov (United States)

Angelov, Plamen; Kordon, Arthur

2010-04-01

A new technique to the design and use of inferential sensors in the process industry is proposed in this paper, which is based on the recently introduced concept of evolving fuzzy models (EFMs). They address the challenge that the modern process industry faces today, namely, to develop such adaptive and self-calibrating online inferential sensors that reduce the maintenance costs while keeping the high precision and interpretability/transparency. The proposed new methodology makes possible inferential sensors to recalibrate automatically, which reduces significantly the life-cycle efforts for their maintenance. This is achieved by the adaptive and flexible open-structure EFM used. The novelty of this paper lies in the following: (1) the overall concept of inferential sensors with evolving and self-developing structure from the data streams; (2) the new methodology for online automatic selection of input variables that are most relevant for the prediction; (3) the technique to detect automatically a shift in the data pattern using the age of the clusters (and fuzzy rules); (4) the online standardization technique used by the learning procedure of the evolving model; and (5) the application of this innovative approach to several real-life industrial processes from the chemical industry (evolving inferential sensors, namely, eSensors, were used for predicting the chemical properties of different products in The Dow Chemical Company, Freeport, TX). It should be noted, however, that the methodology and conclusions of this paper are valid for the broader area of chemical and process industries in general. The results demonstrate that well-interpretable and with-simple-structure inferential sensors can automatically be designed from the data stream in real time, which predict various process variables of interest. The proposed approach can be used as a basis for the development of a new generation of adaptive and evolving inferential sensors that can address the

Then, the paper addresses the challenges facing the geo synthetics discipline. Two major types of challenges are identified: education challenges and technical challenges. Regarding technical challenges, it is recommended that researchers focus on behaviors that are not traditionally considered in geotechnical engineering in order to use geo synthetics to their full potential. Note: this is a significantly expanded version of the keynote paper presented at the 2008 GeoAmericas Conferences. (Author)

Construction of Hypertexts in a Biochemistry Pos- Graduation Discipline

Full Text Available Virtual reality is an innovating manner of comprehending and acting on how the world is and, also, considered a new way of intellectual exercise.  This work took place in a  biochemistry masters discipline (Advanced Formation in ScientificEducation and had as its observation context the forum (on-line tool viability, intending the construction of hypertexts (active  collaborative writing by the 15 registered students in the  discipline in 2008. The discipline was available on the web, in  bioq.educacao.biz , where the students, teachers and monitors couldsubscribe. The virtual space was set with several environments (agenda,classroom, dictionary, email and forum; all of which were used during thediscipline. The forum, called orkuteducation, was destined to the hypertextelaboration, which was focused in three themes: 1º How to work with technology at school;   2º Teaching/learning methods and new information and communication technology; 3º Constructivism. The virtual learning environment had 2,275accesses to its content; being the forum the most visited one, with 1,026.   The built hypertext presented clear ideas about the approached themes, and realized the important role which a qualified teacher plays in the educational process. The new ways of create, organize and interact with information changes the relationship between the subject and the information itself. The hype rtext constitutes "high level computer tools", through which is possible to explore knowledge in a non -linear and interactive way. Hypertext remains a revolutionary concept oforganization and access to information and its generalization impact in society  is not known yet.

Symbiotic Composition and Evolvability

Watson, Richard A.; Pollack, Jordan B.

Several of the Major Transitions in natural evolution, such as the symbiogenic origin of eukaryotes from prokaryotes, share the feature that existing entities became the components of composite entities at a higher level of organisation. This composition of pre-adapted extant entities into a new whole is a fundamentally different source of variation from the gradual accumulation of small random variations, and it has some interesting consequences for issues of evolvability. In this paper we p...

Rethinking "Harmonious Parenting" Using a Three-Factor Discipline Model

Greenspan, Stephen

2006-01-01

Diana Baumrind's typology of parenting is based on a two-factor model of "control" and "warmth". Her recommended discipline style, labeled "authoritative parenting", was constructed by taking high scores on these two factors. A problem with authoritative parenting is that it does not allow for flexible and differentiated responses to discipline…

Discipline, Achievement, and Race: Is Zero Tolerance the Answer?

Science.gov (United States)

Reyes, Augustina H.

2006-01-01

Fifty years after "Brown v Board of Education" inequalities in public education are evident in the disproportionate numbers of Black and Latino students who are held back, often do not graduate from high school, or are removed from school by unforgiving zero tolerance discipline policies. The National Center for Educational Statistics…

How to Enforce Discipline Rules without Trampling Kids' Rights.

Science.gov (United States)

Arnold, Jay

1989-01-01

A Georgia school district standardized discipline procedures, codified offenses, and published the results in booklet form. A clear hierarchy of offenses specifies problems to be handled at the local school, at formal hearings, or at a special disciplinary committee. Students know what to expect, and administrators know how to proceed. (MLF)

The Legal Aspects of Student Discipline in Higher Education.

Science.gov (United States)

Young, D. Parker

The proliferation of court cases involving student discipline testifies to controversy over administrative procedures. Generally, a college's disciplinary policy is viewed as part of the learning process. Courts in the past have ruled favorably on the contractual theory which decrees that an entering student agrees to abide by certain university…

Rapid feedback control and stabilization of an optical tweezers with a budget microcontroller

International Nuclear Information System (INIS)

Nino, Daniel; Wang, Haowei; N Milstein, Joshua

2014-01-01

Laboratories ranging the scientific disciplines employ feedback control to regulate variables within their experiments, from the flow of liquids within a microfluidic device to the temperature within a cell incubator. We have built an inexpensive, yet fast and rapidly deployed, feedback control system that is straightforward and flexible to implement from a commercially available Arduino Due microcontroller. This is in comparison with the complex, time-consuming and often expensive electronics that are commonly implemented. As an example of its utility, we apply our feedback controller to the task of stabilizing the main trapping laser of an optical tweezers. The feedback controller, which is inexpensive yet fast and rapidly deployed, was implemented from hacking an open source Arduino Due microcontroller. Our microcontroller based feedback system can stabilize the laser intensity to a few tenths of a per cent at 200 kHz, which is an order of magnitude better than the laser's base specifications, illustrating the utility of these devices.
