Values through colors. The symbolism of colors in "Prometheus Bound" by the director Telemachus Moudatsakis
Creators: name: Papaleonida, Kyriaki
Publisher: name: Zenodo
Year: 2023

description: Values form the basis that defines human behavior. They are the intangible concepts that shape people's ideas and actions. They exist in the structure and formation of every culture, and they are passed unaffected through time. Values may refer to a person's moral code as it has been shaped by their interaction within the social and political environment. Values, however, can also be innate in humans. Values are inherent in the thought and the actions of the individual, and as such they can be answered everywhere. Human creations, like Art, are the result of man's pursuits, and as that, they constitute the material essence of values. Therefore, ancient drama as a tool of shaping culture (pedagogy), carries a variety of timeless values in its content. This paper aims to investigate the way in which the directorial conception of Prometheus Bound approaches the intangible of values and transforms them into "solid shapes" through their aesthetic depiction. To approach the method in which values are translated from the original text to the stage, we will divide our analysis into two parts. In the first part, we will locate the literary passages of the text in which the values, as presented by the dramatic characters, are perceived. Then, we will analyze the perception of the play by the director and the methods he chooses to depicture the values on the stage through their aesthetic conception. Especially, we will discuss the approach in which the director is used as the intermediate between the original text and the stage, transferring the values, from the intangible form of ideas to their depiction on stage, through colors and scenic objects. The objective here is to study the way that a modern director perceives the values that are contained in a dramatic text and the methods he uses to communicate these values to the audience. What are the criteria by which a modern director chooses the values that he wants to highlight in a play? How are values conveyed through the symbolism of colors? How are they perceived by the audience? All of the above questions will be answered by finding the key-point, in which, values cease to be intangible, and they are transformed into theatrical multi-codes.

description: It is a well-known fact that the analysis of the time dimension represents a useful instrument both for charting the complex field of social changes in which we find ourselves, as well as for defining an efficient code for interpretation. In particular, a reflection on time and gender allows us to bring to the foreground relevant dimensions of these changes. By making use of the results of some of the research on young women’s biographic construction, the article aims at highlighting the relationship between gender, the acknowledgment of the multiplicity of human times, and the present restructuring of biographical narratives.

description: A linear gradient mode must have no observable dynamical effect on short distance physics. We confirm this by showing that if there was such a gradient mode extending across the whole observable Universe, it would not cause any hemispherical asymmetry in the power of CMB anisotropies, as long as Maldacena's consistency condition is satisfied. To study the effect of the long wavelength mode on short wavelength modes, we generalize the existing second order Sachs-Wolfe formula in the squeezed limit to include a gradient in the long mode and to account for the change in the location of the last scattering surface induced by this mode. Next, we consider effects that are of second order in the long mode. A gradient mode $Φ= \boldsymbol q\cdot \boldsymbol x$ generated in Single-field inflation is shown to induce an observable quadrupole moment. For instance, in a matter-dominated model it is equal to $Q=5 (\boldsymbol q\cdot \boldsymbol x)^2 /18$. This quadrupole can be canceled by superposition of a quadratic perturbation. The result is shown to be a nonlinear extension of Weinberg's adiabatic modes: a long-wavelength physical mode which looks locally like a coordinate transformation.

description: Electron energy-loss spectroscopy (EELS) and cathodoluminescence (CL) are widely used experimental techniques for characterization of nanoparticles. The discrete dipole approximation (DDA) is a numerically exact method for simulating interaction of electromagnetic waves with particles of arbitrary shape and internal structure. In this work we extend the DDA to simulate EELS and CL for particles embedded into arbitrary (even absorbing) unbounded host medium. The latter includes the case of the dense medium, supporting the Cherenkov radiation of the electron, which has never been considered in EELS simulations before. We build a rigorous theoretical framework based on the volume-integral equation, final expressions from which are implemented in the open-source software package ADDA. This implementation agrees with both the Lorenz-Mie theory and the boundary-element method for spheres in vacuum and moderately dense host medium. And it successfully reproduces the published experiments for particles encapsulated in finite substrates. The latter is shown for both moderately dense and Cherenkov cases - a gold nanorod in $\text{SiO}_{\text{2}}$ and a silver sphere in $\text{SiN}_{\text{x}}$ respectively.

description: The paper defends the thesis that analysis of time meaning in a context of philosophy of physical and mathematical natural sciences and philosophical anthropology allows to clear basis of human being and to construct special model of general understanding of time as a creation of nature or creation of human. Regulations on discretization and virtual nature of cultural interaction, mutual tension of limits of cultural and historical process allow connecting philosophy of the nature and philosophical anthropology with system of categories (energy, weight, distance, etc.). It finds application both in the physical and mathematical sphere and in the field of humanitarian studies. We can make a conclusion that neither nature nor human create the time. Time is an imaginary phenomenon connecting human activity and natural processes in the limits of human consciousness.

description: The physics of the Mott metal-insulator transition (MIT) has attracted huge interest in the last decades. However, despite broad efforts, some key theoretical predictions are still lacking experimental confirmation. In particular, it is not clear whether the large coherent Fermi surface survives in immediate proximity to the bandwidth-controlled first-order MIT. A quantitative experimental verification of the predicted behavior of the quasiparticle effective mass, renormalized by many-body interactions, is also missing. Here we address these issues by employing organic $κ$-type salts as exemplary quasi-two-dimensional bandwidth-controlled Mott insulators and gaining direct access to their charge carrier properties via magnetic quantum oscillations. We trace the evolution of the effective cyclotron mass as the conduction bandwidth is tuned very close to the MIT by means of precisely controlled external pressure. We find that the sensitivity of the mass renormalization to tiny changes of the bandwidth is significantly stronger than theoretically predicted and is even further enhanced upon entering the transition region where the metallic and insulating phases coexist. On the other hand, even at its very edge of stability the metallic ground state preserves a large coherent Fermi surface with no significant enhancement of scattering.

description: Fractional Chern insulators (FCIs) are lattice generalizations of the conventional fractional quantum Hall effect (FQHE) in two-dimensional (2D) electron gases. They typically arise in a 2D lattice without time-reversal symmetry when a nearly flat Bloch band with nonzero Chern number is partially occupied by strongly interacting particles. Band topology and interactions endow FCIs exotic topological orders which are characterized by the precisely quantized Hall conductance, robust ground-state degeneracy on high-genus manifolds, and fractionalized quasiparticles. Since in principle FCIs can exist at zero magnetic field and be protected by a large energy gap, they provide a potentially experimentally more accessible avenue for observing and harnessing FQHE phenomena. Moreover, the interplay between FCIs and lattice-specific effects that do not exist in the conventional continuum FQHE poses new theoretical challenges. In this chapter, we provide a general introduction of the theoretical model and numerical simulation of FCIs, then pay special attention on the recent development of this field in moiré materials while also commenting on potential alternative implementations in cold atom systems. With a plethora of exciting theoretical and experimental progress, topological flat bands in moiré materials such as magic-angle twisted bilayer graphene on hexagonal boron nitride have indeed turned out to be a remarkably versatile platform for FCIs featuring an intriguing interplay between topology, geometry, and interactions.

description: We propose random tight-binding models that host macroscopically degenerate zero energy modes and belong to the unitary class. Specifically, we employ the molecular-orbital representation, where a Hamiltonian is constructed by a set of non-orthogonal orbitals composed of linear combinations of atomic orbitals. By setting the coefficients appearing in molecular orbitals to be random U(1) variables, we can make the models belong to the unitary class. We find two characteristic behaviors that are distinct from the random-real-valued molecular-orbital model. Firstly, a finite energy gap opens on top of the degenerate zero energy modes. Secondly, besides the zero energy modes, we also argue that the band center of the finite energy modes is critical, which is inherited from the dual counterpart, namely, the random-phase model on a bipartite lattice. Furthermore, as a by-product of this model-construction scheme, we also construct the random tight-binding model on a composite lattice, where we also find a realization of critical states.

description: We investigate the eigenstate thermalization hypothesis (ETH) in integrable models, focusing on the spin-1/2 isotropic Heisenberg (XXX) chain. We provide numerical evidence that ETH holds for typical eigenstates (weak ETH scenario). Specifically, using a numerical implementation of state-of-the-art Bethe ansatz results, we study the finite-size scaling of the eigenstate-to-eigenstate fluctuations of the reduced density matrix. We find that fluctuations are normally distributed, and their standard deviation decays in the thermodynamic limit as L^{-1/2}, with L the size of the chain. This is in contrast with the exponential decay that is found in generic non-integrable systems. Based on our results, it is natural to expect that this scenario holds in other integrable spin models and for typical local observables. Finally, we investigate the entanglement properties of the excited states of the XXX chain. We numerically verify that typical mid-spectrum eigenstates exhibit extensive entanglement entropy (i.e., volume-law scaling).

description: Background: Deep learning (DL)-based head and neck lymph node level (HN_LNL) autodelineation is of high relevance to radiotherapy research and clinical treatment planning but still underinvestigated in academic literature. Methods: An expert-delineated cohort of 35 planning CTs was used for training of an nnU-net 3D-fullres/2D-ensemble model for autosegmentation of 20 different HN_LNL. A second cohort acquired at the same institution later in time served as the test set (n=20). In a completely blinded evaluation, 3 clinical experts rated the quality of DL autosegmentations in a head-to-head comparison with expert-created contours. For a subgroup of 10 cases, intraobserver variability was compared to the average DL autosegmentation accuracy on the original and recontoured set of expert segmentations. A postprocessing step to adjust craniocaudal boundaries of level autosegmentations to the CT slice plane was introduced and the effect on geometric accuracy and expert rating was investigated. Results: Blinded expert ratings for DL segmentations and expert-created contours were not significantly different. DL segmentations with slice plane adjustment were rated numerically higher (mean, 81.0 vs. 79.6,p=0.185) and DL segmentations without slice plane adjustment were rated numerically lower (77.2 vs. 79.6,p=0.167) than manually drawn contours. DL segmentations with CT slice plane adjustment were rated significantly better than DL contours without slice plane adjustment (81.0 vs. 77.2,p=0.004). Geometric accuracy of DL segmentations was not different from intraobserver variability (mean, 0.76 vs. 0.77, p=0.307). Conclusions: We show that a nnU-net 3D-fullres/2D-ensemble model can be used for highly accurate autodelineation of HN_LNL using only a limited training dataset that is ideally suited for large-scale standardized autodelineation of HN_LNL in the research setting.

description: As a step towards a more accurate modelling of redshift-space distortions in galaxy surveys, we develop a general description of the probability distribution function of galaxy pairwise velocities within the framework of the so-called streaming model. For a given galaxy separation $\vec{r}$, such function can be described as a superposition of virtually infinite local distributions. We characterize these in terms of their moments and then consider the specific case in which they are Gaussian functions, each with its own mean $μ$ and dispersion $σ$. Based on physical considerations, we make the further crucial assumption that these two parameters are in turn distributed according to a bivariate Gaussian, with its own mean and covariance matrix. Tests using numerical simulations explicitly show that with this compact description one can correctly model redshift-space distorsions on all scales, fully capturing the overall linear and nonlinear dynamics of the galaxy flow at different separations. In particular, we naturally obtain Gaussian/exponential, skewed/unskewed distribution functions, depending on separation as observed in simulations and data. Also, the recently proposed single-Gaussian description of redshift-space distortions is included in this model as a limiting case, when the bivariate Gaussian is collapsed to a two-dimensional Dirac delta function. We also show how this description naturally allows for the Taylor expansion of $1+ξ_S(\vec{s})$ around $1+ξ_R(r)$, which leads to the Kaiser linear formula when truncated to second order, expliciting its connection with the moments of the velocity distribution functions. More work is needed, but these results indicate a very promising path to make definitive progress in our program to improve RSD estimators.

Besonders das Content-Marketing verfolgt neben der Umsatzsteigerung auch das Ziel, KonsumentInnen einen Mehrwert zu bieten. Um zu verstehen, wie die Kommunikation zwischen KonsumentInnen und Unternehmen in Nischen-Branchen funktioniert, ist das Ziel der vorliegenden Arbeit die Analyse von erfolgversprechenden Kommunikationsstrategien und die Gegenüberstellung mit Hürden bei der praktischen Umsetzung. Dazu wurde eine Unternehmensanalyse mitsamt ExpertInneninterviews in einem Unternehmen zu Mobilitätsforschung und Raumplanung durchgeführt. Ergebnisse zeigten den positiven Effekt einer verstärkten Kommunikationsstrategie auf die Reichweite und den Bekanntheitsgrad des Unternehmens. Die Inhaltsanalyse ergab Faktoren, welche vor allem auf personelle, finanzielle und organisatorische Hürden durch die Unternehmensgröße und die Branchenumgebung deuten. Weitere Forschung könnte die Branchenumgebung untersuchen und etwaige personelle und organisatorische Hürden bei anderen Unternehmen nicht identifizieren. Dennoch ist die Branche aufgrund der Finanzierungsform nicht auf die Investition in Kommunikationsstrategien angewiesen.

In addition to increasing sales, content marketing in particular aims to offer consumers added value. To understand how communication between consumers and companies works in niche industries, the aim of this work is to analyze promising communication strategies and to compare them with the hurdles in their practical implementation. For this purpose, a company analysis including expert interviews conducted in a company on mobility research and spatial planning. Results showed the positive effect of a strengthened communication strategy on the company's reach and awareness. The content analysis revealed factors that primarily point to personal, financial, and organizational hurdles caused by the size of the company and the industry environment. Further research could examine the industry environment and not identify any human and organizational hurdles at other companies. Nevertheless, due to the form of financing, the industry is not dependent on investing in communication strategies, based on the outcomes of the paper.

An Ethical Indicator in the Decision-Making Process. Transcendent Motives
Creators: name: Puig, Marta López-Jurado
Publisher: name: JSSE - Journal of Social Science Education
Year: 2005

description: The conceptualization of transcendent motives - together with the extrinsic and intrinsic motives - opens a channel to unite theory and practice in the realm of moral education. The conceptual axis of the analysis is the decision-making process framed in a context where there are "others" that receive the impact of our actions. Transcendent motives clarify the real value we assign to those others, if we treat them like persons, or rather "in function of, or "as a means to" further our personal interests. Rational motivation based on these motives makes us prudent and develops in us the valuative knowledge that serves us to discover in an experiential (rather than theoretical) manner personal realities. Via the case method students are taught the three types of criteria needed to learn how to internalize persons as a value in and of themselves.

Coupled Boltzmann computation of mixed axion neutralino dark matter in the SUSY DFSZ axion model

description: The supersymmetrized DFSZ axion model is highly motivated not only because it offers solutions to both the gauge hierarchy and strong CP problems, but also because it provides a solution to the SUSY mu problem which naturally allows for a Little Hierarchy. We compute the expected mixed axion-neutralino dark matter abundance for the SUSY DFSZ axion model in two benchmark cases-- a natural SUSY model with a standard neutralino underabundance (SUA) and an mSUGRA/CMSSM model with a standard overabundance (SOA). Our computation implements coupled Boltzmann equations which track the radiation density along with neutralino, axion (produced thermally (TH) and via coherent oscillations (CO)), saxion (TH- and CO-produced), axino and gravitino densities. In the SUSY DFSZ model, axions, axinos and saxions go through the process of freeze-in-- in contrast to freeze-out or out-of-equilibrium production as in the SUSY KSVZ model-- resulting in thermal yields which are largely independent of the re-heat temperature. We find the SUA case with suppressed saxion-axion couplings (ξ=0) only admits solutions for PQ breaking scale f_a~< 5\times 10^{12} GeV where the bulk of parameter space tends to be axion-dominated. For SUA with allowed saxion-axion couplings (ξ=1), then f_a values up to ~ 2\times 10^{14} GeV are allowed. For the SOA case, almost all of SUSY DFSZ parameter space is disallowed by a combination of overproduction of dark matter, overproduction of dark radiation or violation of BBN constraints. An exception occurs at very large f_a~ 10^{15}-10^{16} GeV where large entropy dilution from CO-produced saxions leads to allowed models.

Imaginary components of out-of-time correlators and information scrambling for navigating the learning landscape of a quantum machine learning model

description: We introduce and analytically illustrate that hitherto unexplored imaginary components of out-of-time correlators can provide unprecedented insight into the information scrambling capacity of a graph neural network. Furthermore, we demonstrate that it can be related to conventional measures of correlation like quantum mutual information and rigorously establish the inherent mathematical bounds (both upper and lower bound) jointly shared by such seemingly disparate quantities. To consolidate the geometrical ramifications of such bounds during the dynamical evolution of training we thereafter construct an emergent convex space. This newly designed space offers much surprising information including the saturation of lower bound by the trained network even for physical systems of large sizes, transference, and quantitative mirroring of spin correlation from the simulated physical system across phase boundaries as desirable features within the latent sub-units of the network (even though the latent units are directly oblivious to the simulated physical system) and the ability of the network to distinguish exotic spin connectivity(volume-law vs area law). Such an analysis demystifies the training of quantum machine learning models by unraveling how quantum information is scrambled through such a network introducing correlation surreptitiously among its constituent sub-systems and open a window into the underlying physical mechanism behind the emulative ability of the model.

We present the inflationary predictions for this potential, $n_s$, $r$, and $α=\mathrm{d}n_s/\mathrm{d}\ln k$. In addition, we assume standard thermal history after inflation, and using this, for considered potential, we show compatible regions for the $n_s$, $r$ within the recent BICEP/Keck results.

"Acting as a Moral Human Being - Neglecting Economic Studies". Situation, Concepts and Challenges of Economic Studies at German Primary Schools

Year: 2005

description: Children are affected by poverty, unemployment and pollution; they are a target group for firms. Without doubt they have to deal with the problems of economic allocation, distribution and stabilisation. But children are also individuals with needs and purchasing power, who make economic decisions themselves and influence those of others. Children interpret and construct their own explanations for these phenomena and build their own problem-solving strategies. Do shops create goods themselves? Do banks produce money? Is the function of a bank the protection of money against theft? Does the government tell people which job to do? Can everybody choose what he or she wants? Is a car more expensive than a jumper because it is bigger or because it can be driven? If school is supposed to help children understand and act in the world they are living in, then even at primary school economic world can not be blanked out. The main aim of this contribution is to analyse, if German curricula for primary schools as well as the main association of primary school attach importance to the economic phenomena in a child's world. As these concepts are not developed by experts of economic education but by experts of primary education, I want to contrast these aims with three concepts respectively aims of economic education at primary school developed by experts of economic education. So the extremes can be shown: Which importance could economic education get und which is currently attached. However, also the concepts and aims of constructors of concepts for economic education do not satisfy totally. Either they derive their aims directly from economics as a science or from economic situations children take part or should know about. They draw out what children should know about or what children could do to learn about, seldom is pointed out, what children should be able to understand and responsibly act. Therefore an understanding of children's construction of economic world is necessary. These constructs are analysed by economic psychologists. These results allow referring to the children's naive theories in order to help them understand and act in their economic world. As pure analysis does not satisfy by discovering lacks, I will discuss competences which should be related to the approach of experts of children's education as well as to experts of economic education, taking into account the results of economic psychologists. Finally, without winning the teacher children will not learn anything about economics at school, so I will finish with an approach to win the teachers.

description: We propose a CP-safe gravity mediation model, where the phases of the Higgs B parameter, scalar trilinear couplings and gaugino mass parameters are all aligned. Since all dangerous CP violating phases are suppressed, we are now safe to consider low-energy SUSY scenarios. As an application, we consider a gravity mediation model explaining the observed muon $g-2$ anomaly. The CP-safe property originates in two simple assumptions: SUSY breaking in the Kähler potential and a shift symmetry of a SUSY breaking field $Z$. As a result of the shift symmetry, the imaginary part of $Z$ behaves as a QCD axion, leading to an intriguing possibility: the strong CP problem in QCD and the SUSY CP problem are solved simultaneously.

The Social Interplay of Disciplinarity and Interdisciplinarity. Some Introductory Remarks
Creators: name: Hedtke, Reinhold
Publisher: name: JSSE - Journal of Social Science Education
Year: 2006

description: Social Science Education as a subject field in schools is an intrinsic pluridisciplinary feature, whatever disciplines are included, however it may be organised and wherever it may be institutionalised. Civic education, economic education, social education and historical education each comprise several academic disciplines even if they are thought to be completely independent subjects. From the start on, disciplinarity and interdisciplinarity are on the agenda for any subject related to social science education and are one of its main problems. For these introductory remarks interdisciplinarity can be simply defined as relating two or more academic disciplines or school subjects to each other if this is done in a purposeful, systematic, explicit and reflective way. The overarching goal is to improve education that is to enhance students' understandings of the worlds and their abilities to act within and towards them. A relationship between disciplines or subjects which misses one or more of the four characteristics can be called pluridisciplinary or multidisciplinary (cf. Audigier 2006). In the following I first want to discuss some aspects of disciplinarity and interdisciplinarity at schools and at universities and the weakness of interdisciplinarity. I sketch some social science based ideas on the interrelationship between the subject structure of the academic world and the world of schools (3.) and of some tendency to commonalities or even unification of social sciences and related competencies (4.). I conclude with some remarks on different kinds of knowledge (5.). Last but not least, I'll give an overview on the papers in this issue of the Journal of Social Science Education (6.).

A Platform for a Shared Discourse of Interdisciplinary Education
Creators: name: Klein, Julie Thompson
Publisher: name: JSSE - Journal of Social Science Education
Year: 2006

description: “Disciplinarity” and “interdisciplinarity” have become keywords for knowledge and education in the twenty-first century. This development requires that administrators, curriculum planners, and teachers at all levels of the educational system have a common understanding of both terms and their relationship. The primary case study is the school level in the United States. Yet, comparisons with other nations suggest a platform for longer-term international dialogue that bridges the discourses of interdisciplinarity across national contexts as well as school and university levels. A shared discourse and programs of teacher training require awareness of historical contexts of interdisciplinary education, major terminology for distinguishing design models, characteristic pedagogical approaches, and related learning skills.

Practices of Disciplinarity and Interdisciplinarity in Quebec Elementary Schools: Results of Twenty Years of Research
Creators: name: Lenoir, Yves
Publisher: name: JSSE - Journal of Social Science Education
Year: 2006

description: This article presents a synthesis of different research projects that have been carried out in the province of Quebec, Canada over the past 20 years concerning the representations and practices of elementary teachers regarding the relative importance given to subject matter and the use of interdisciplinarity in their teaching practice. The first section will explain the context of the Quebec school system on a socio-historical and political level and review the emergence of the concept of interdisciplinarity in Quebec. The second section will present succinctly the different research projects that have been conducted since 1980 and the conceptual framework they were based on. The third section will consider the main results of the various research projects from two angles: first, the representations and practices of the teachers regarding interdisciplinarity; secondly, the relative importance and role that the teachers give to interdisciplinarity. In the conclusion, we will highlight among other things the central position teachers give to the role of socialization and their minimal consideration for the teaching of disciplinary knowledge.

description: The question whether the total gluon angular momentum in the nucleon can be decomposed into its spin and orbital parts without conflict with the gauge-invariance principle has been an object of long-lasting debate. Despite a remarkable progress achieved through the recent intensive researches, the following two issues still remains to be clarified more transparently. The first issue is to resolve the apparent conflict between the proposed gauge-invariant decomposition of the total gluon angular momentum and the textbook statement that the total angular momentum of the photon cannot be gauge-invariantly decomposed into its spin and orbital parts. We show that this problem is also inseparably connected with the uniqueness or non-uniqueness problem of the nucleon spin decomposition. The second practically more important issue is that, among the two physically inequivalent decompositions of the nucleon spin, i.e. the "canonical" type decomposition and the "mechanical" type decomposition, which can we say is more physical or closer to direct observation ? In the present paper, we try to answer both these questions as clearly as possible.

Interdisciplinarity at School – Theoretical and Practical Questions Regarding History, Geography and Civic Education
Creators: name: Audigier, François
Publisher: name: JSSE - Journal of Social Science Education
Year: 2006

description: It has been a long time that interdisciplinarity is a recommended orientation and practice in various educational systems. It becomes more and more actual with some teaching objects that do not fit simply with the ordinary subjects present at school. These objects are often found in «educations to… » like education to health, to sustainability, to media, to citizenship, etc. To begin with, we examine how ambiguous can be the term of «interdisciplinarity»; we will use the more neutral term «polydisciplinarity». We also remind the reader that this latter needs disciplines to be put into practice. Then we differentiate school subjects according to their objects and their contribution to pupils’ training. That leads us to distinguish on one hand an external polydisciplinarity which studies the links between all social sciences (mainly history, geography and what concerns citizenship) and other disciplines from, on the other hand, an internal polydisciplinarity within the social sciences. To conclude, we introduce the issue of knowing and understanding what a society is about, in particular knowing and understanding our society nowadays. This issue echoes the one about the common culture, about a shared world conception which is sufficient to live together in our political communities.

Promotion of Interdisciplinarity Competence as a Challenge for Higher Education
Creators: name: Godemann, Jasmin
Publisher: name: JSSE - Journal of Social Science Education
Year: 2006

description: Interdisciplinary co-operation, no matter whether in research or in teaching, makes high demands on all participating players. To reach a shared understanding is the main goal and, at the same time, the major challenge. In interdisciplinary work contexts, experts with different qualities, varying knowledge bases and disciplinary perspectives come together. The extent to which an understanding is possible depends on the ability to exchange knowledge in such a way that it becomes part of a common knowledge base, as well as on one’s own perception of the problem. Therefore, all persons involved must be aware of being both expert and layperson at the same time. Furthermore, they need to accept the perspective of all those who are foreign to their subject during the communication process. The ability to work and to communicate in an interdisciplinary context does not arise all by itself but may be promoted during the academic education. The dimension of knowledge integration will be described in the following, with recourse to psychological research about expert-layperson communication and regarding assumptions about the adoption of perspectives. This paper shows that interdisciplinary competency and the ability to solve complex problems can be promoted at universities. This is illustrated by the case study of the “Sustainability Study Programme.”
