A tudományterületi sajátosságok következményei a kutatásban, az oktatásban és a felsőoktatási intézmények vezetésében (The consequences of disciplinary difference on teaching, research and institutional management of higher education)

A szerző tanulmányában vizsgálja a tudományterületek különbségeinek következményeit az oktatásban, a kutatásban és a felsőoktatási intézmények irányításában. A tanulmány első felében a tudományterületek episztemológiai és közösségi különbségeit tárgyalja Becher és Trowler (2001) népszerű kategorizálása alapján. A tanulmány második felében a tudományszerveződésre, a publikációs gyakorlatra, a doktori képzésre, az oktatás céljára és formáira, a diákok tudásképére, valamint a menedzsmentfelfogásra gyakorolt hatást mutatja be. A konklúzióban egyrészt a minőség- és teljesítményértékelési rendszerek differenciált megközelítésének szükségességére hívja fel a figyelmet, másrészt arra, hogy a Bologna-rendszer és az élethosszig tartó tanulás erősödésének következményeként egy-egy mesterszakon nemcsak a hallgatóság háttere, előismerete lesz sokszínű, hanem a tudásról alkotott képe is. Ez újfajta oktatói szerepeket és oktatási megközelítéseket tesz szükségessé. ________ In the article the consequences of disciplinary difference on teaching, research and institutional management is examined. In the first part of the paper the epistemological and sociological differences of scientific disciplines are summarized based on the popular typology of Becher and Trowler (2001). In the second part the influence of differences on organisation of sciences, publication practices, PhD studies, the goal and form of teaching, students’ conception of knowledge as well as on the understanding on management and leadership are discussed. In the conclusions, attention is drawn on the necessity of differentiation in quality and performance management processes. Another conclusion is that new roles for teachers and approaches for teaching is required if students’ conception of knowledge become more heterogeneous which is the result of result of life long learning and Bologna-reform.

Publicidad subliminal en campañas electorales: entre el mito y la realidad

El interés por la publicidad subliminal ha ocupado un lugar destacado en las últimas décadas en el seno de distintas disciplinas científicas, si bien no termina de haber un consenso acerca de su verdadero poder. Sin embargo, en el campo de la Comunicación Política apenas se encuentran referencias a esta práctica por más que se vengan reportando en los medios desde hace años supuestos casos de anuncios subliminales en campañas electorales. En el presente artículo se propone una aproximación al uso de lo subliminal en la política, para intentar dilucidar si nos encontramos tan sólo ante un mito, como se ha dicho tantas veces al hablar de esta técnica, o por el contrario ante una realidad.

DNA in Amphibian and Reptile Venom Permits Access to Genomes Without Specimen Sacrifice

Amphibian defensive skin secretions and reptile venoms are rich sources of bioactive peptides with potential pharmacological/pharmaceutical applications. As amphibian and reptile populations are in rapid global decline, our research
group has been developing analytical methods that permit generation of robust molecular data from non-invasive skin secretion samples and venom samples. While previously we have demonstrated that parallel proteome and venom gland
transcriptome analyses can be performed on such samples, here we report the presence of DNA that facilitates the more widely-used applications of gene sequencing, such as molecular phylogenetics, in a non-invasive manner that circumvents specimen sacrifice. From this “surrogate” tissue, we acquired partial 12S and 16S rRNA gene sequences that are presented for illustration purposes. Thus from a single sample of amphibian skin secretion and reptile venom, robust and complementary proteome, transcriptome and genome data can be generated for applications in diverse scientific disciplines.

Professionsmaktens framställning av fenomenet ADHD - en diskursanalys

In the body of knowledge surrounding ADHD there is a power struggle regarding which interpretations and perspectives should prevail. Representatives from various scientific disciplines and professions write and publish articles about the diagnosis based on their respective points of view. These articles are the focus of this thesis. Among other things it can be seen in these examined articles that, the prevalence of ADHD is higher amongst established bodies of social care, and that there is a lack of knowledge regarding the diagnosis in social systems such as schools and social services. Our aim with this study is to highlight how professionals within the Swedish contemporary field of knowledge surrounding ADHD create significance and meaning of the phenomenon. Based on Jonathan Potters discourse analysis, we focus on how ADHD is described by professionals in contemporary Swedish articles about ADHD and also on how these descriptions become valid and credible in these texts. The approach used in our case has been article analysis, based on Potter's rhetorical toolbox that includes both theory and method in one. ADHD is widely presented in the articles with descriptions ranging from a cultural disease constructed by prevailing social climate to being a genetic abnormality. Using various rhetorical strategies it is possible to establish totally different groups of interpretative repertoires as all true. In this thesis, we also discuss the possible consequences of these various explanations and constructions within social work and society at large.

Technical appendix to Macrodynamics of economics: a bibliometric history

A history of specialties in economics since the late 1950s is constructed on the basis of a large corpus of documents from economics journals. The production of this history relies on a combination of algorithmic methods that avoid subjective assessments of the boundaries of specialties: bibliographic coupling, automated community detection in dynamic networks, and text mining. These methods uncover a structuring of economics around recognizable specialties with some significant changes over the period covered (1956–2014). Among our results, especially noteworthy are (1) the clear-cut existence of ten families of specialties, (2) the disappearance in the late 1970s of a specialty focused on general economic theory, (3) the dispersal of the econometrics-centered specialty in the early 1990s and the ensuing importance of specific econometric methods for the identity of many specialties since the 1990s, and (4) the low level of specialization of individual economists throughout the period in contrast to physicists as early as the late 1960s.

"Last-Mile" preparation for a potential disaster - Interdisciplinary approach towards tsunami early warning and an evacuation information system for the coastal city of Padang, Indonesia

Extreme natural events, like e.g. tsunamis or earthquakes, regularly lead to catastrophes with dramatic consequences. In recent years natural disasters caused hundreds of thousands of deaths, destruction of infrastructure, disruption of economic activity and loss of billions of dollars worth of property and thus revealed considerable deficits hindering their effective management: Needs for stakeholders, decision-makers as well as for persons concerned include systematic risk identification and evaluation, a way to assess countermeasures, awareness raising and decision support systems to be employed before, during and after crisis situations. The overall goal of this study focuses on interdisciplinary integration of various scientific disciplines to contribute to a tsunami early warning information system. In comparison to most studies our focus is on high-end geometric and thematic analysis to meet the requirements of smallscale, heterogeneous and complex coastal urban systems. Data, methods and results from engineering, remote sensing and social sciences are interlinked and provide comprehensive information for disaster risk assessment, management and reduction. In detail, we combine inundation modeling, urban morphology analysis, population assessment, socioeconomic analysis of the population and evacuation modeling. The interdisciplinary results eventually lead to recommendations for mitigation strategies in the fields of spatial planning or coping capacity. © Author(s) 2009.

The transformed-stationary approach: a generic and simplified methodology for non-stationary extreme value analysis

Statistical approaches to study extreme events require, by definition, long time series of data. In many scientific disciplines, these series are often subject to variations at different temporal scales that affect the frequency and intensity of their extremes. Therefore, the assumption of stationarity is violated and alternative methods to conventional stationary extreme value analysis (EVA) must be adopted. Using the example of environmental variables subject to climate change, in this study we introduce the transformed-stationary (TS) methodology for non-stationary EVA. This approach consists of (i) transforming a non-stationary time series into a stationary one, to which the stationary EVA theory can be applied, and (ii) reverse transforming the result into a non-stationary extreme value distribution. As a transformation, we propose and discuss a simple time-varying normalization of the signal and show that it enables a comprehensive formulation of non-stationary generalized extreme value (GEV) and generalized Pareto distribution (GPD) models with a constant shape parameter. A validation of the methodology is carried out on time series of significant wave height, residual water level, and river discharge, which show varying degrees of long-term and seasonal variability. The results from the proposed approach are comparable with the results from (a) a stationary EVA on quasi-stationary slices of non-stationary series and (b) the established method for non-stationary EVA. However, the proposed technique comes with advantages in both cases. For example, in contrast to (a), the proposed technique uses the whole time horizon of the series for the estimation of the extremes, allowing for a more accurate estimation of large return levels. Furthermore, with respect to (b), it decouples the detection of non-stationary patterns from the fitting of the extreme value distribution. As a result, the steps of the analysis are simplified and intermediate diagnostics are possible. In particular, the transformation can be carried out by means of simple statistical techniques such as low-pass filters based on the running mean and the standard deviation, and the fitting procedure is a stationary one with a few degrees of freedom and is easy to implement and control. An open-source MAT-LAB toolbox has been developed to cover this methodology, which is available at https://github.com/menta78/tsEva/(Mentaschi et al., 2016).

Measuring nursing competencies in the operating theatre: instrument development and psychometric analysis using Item Response Theory

BACKGROUND: Concern about the process of identifying underlying competencies that contribute to effective nursing performance has been debated with a lack of consensus surrounding an approved measurement instrument for assessing clinical performance. Although a number of methodologies are noted in the development of competency-based assessment measures, these studies are not without criticism. RESEARCH AIM: The primary aim of the study was to develop and validate a Performance Based Scoring Rubric, which included both analytical and holistic scales. The aim included examining the validity and reliability of the rubric, which was designed to measure clinical competencies in the operating theatre. RESEARCH METHOD: The fieldwork observations of 32 nurse educators and preceptors assessing the performance of 95 instrument nurses in the operating theatre were used in the calibration of the rubric. The Rasch model, a particular model among Item Response Models, was used in the calibration of each item in the rubric in an attempt at improving the measurement properties of the scale. This is done by establishing the 'fit' of the data to the conditions demanded by the Rasch model. RESULTS: Acceptable reliability estimates, specifically a high Cronbach's alpha reliability coefficient (0.940), as well as empirical support for construct and criterion validity for the rubric were achieved. Calibration of the Performance Based Scoring Rubric using Rasch model revealed that the fit statistics for most items were acceptable. CONCLUSION: The use of the Rasch model offers a number of features in developing and refining healthcare competency-based assessments, improving confidence in measuring clinical performance. The Rasch model was shown to be useful in developing and validating a competency-based assessment for measuring the competence of the instrument nurse in the operating theatre with implications for use in other areas of nursing practice.

Reaching for the heavenly bead of teaching through structured problem solving

Japanese Lesson Study has provoked intense interest since it became known in the mid-1990s due to descriptions of the "typical" Japanese abacus - the soroban - with its Earth and Heaven beads as its metaphor, this paper examines the Earth beads necessary to reach the goal of a Heavenly bead - that is, an effective structured problem-solving mathematics lesson.

Graduate nurse experiences of support : a review

UNLABELLED: The first year of practice as a nurse is recognized as stressful. Graduate nurses (GNs) report gaps in their education, reality shock, burnout and other negative experiences that influence their intentions to remain in nursing. OBJECTIVES: The aim of this literature review was to gain a greater understanding of the experiences of GNs. REVIEW METHODS: It included thirty-six articles that focused on GNs and their transition to nursing, as part of a graduate nurse program (GNP), from 2005 to present. RESULT: The review identified three main themes that influence the transition from student to registered nurse. These themes included, 1) feeling stressed and overwhelmed by nursing responsibilities, 2) the amount of support from senior nurses and 3) the importance of feedback on their performance as nurses. CONCLUSIONS: Further research that is focused on the support and feedback provided to new nurses is needed.

Expert science teacher's notion of scientific literacy

This paper will report on the way expert science teachers’ conceive of scientific literacy in their classrooms, the values related to scientific literacy they hold and how this conception and the underpinning values affect their teaching practice. Three perceived expert science teachers who teach both at senior and middle school levels and across the range of sub-disciplines (one senior biology, one senior chemistry and one senior physics) were interviewed about their understanding of scientific literacy and how this influenced their teaching practice. The three teachers were video recorded teaching a junior science class and a senior science class. The data were analysed to identify values that underpin their conceptions of science and science education. The analysis focussed on the matching of the verbalised conceptions and values with their practice of teaching science. This paper will report on these data.
