We developed a lesson where students construct a qualitative representation to learn how clock genes are regulated. Qualitative representations provide a non-numerical description of system behavior, focusing on causal relation-ships and system states. They align with human reasoning about system dy-namics and serve as valuable learning tools for understanding both domain-specific systems and developing broader systems thinking skills.The lesson, designed for upper secondary and higher education, is imple-mented in the DynaLearn software at Level 4, where students can model feedback loops. Students construct the representation step by step, guided by a structured workbook and built-in support functions within the software. At each step, they run simulations to examine system behavior and reflect on the results through workbook questions. To ensure scientific accuracy, the representation and workbook were evaluated by domain experts.The lesson begins with modeling how increasing BMAL:CLOCK activity enhances the transcription of PER and CRY genes through binding to the E-box. Next, students explore how mRNA production and degradation—two opposing processes—regulate mRNA levels. This is followed by modeling translation at the ribosomes, where PER and CRY proteins are synthesized and subsequently degraded, again illustrating competing regulatory process-es. Students then model how PER and CRY proteins form a complex that translocates to the nucleus, inhibiting CLOCK:BMAL binding and establish-ing a negative feedback loop. Finally, they extend their understanding by ex-ploring how CLOCK:BMAL also regulates the AVP gene, linking clock genes to broader physiological processes.

This article examines two areas of tension within environmental ethics literature and relates them to the case study of the animal representation in the Dutch media. On the one hand, there is a tension between those who propagate clear division between anthropocentric and non-anthropocentric views; on the other hand, there is a tension between the land ethics perspective and animal right proponents. This article examines the media representation of animals using content analysis, and links the findings back to the areas of tension within environmental ethics. The main findings indicate that the division between anthropocentric and ecocentric perspectives is still relevant for evaluating the human-animal relations, while the convergence of the land ethics and animal rights perspectives can be helpful in explaining why this division is relevant. This is a post-peer-review, pre-copyedit version of an article published in "Environmental Processes".The final authenticated version is available online at: https://doi.org/10.1007/s40710-014-0025-7 https://www.linkedin.com/in/helenkopnina/

Humans use metaphors in thinking. Most metaphors are visual. In processing information stimuli the mind depends partly on visual codes. Information is processed and stored through two channels: one for non-verbal information and another for verbal information. The two different areas of information in the brain are interconnected. The information is stored in patterns that form an inner representation of how individuals perceive their reality and their self. The active processing of new information, remembering and the self-image are related phenomena, that influence each other, sometimes leading to biased interpretation or even reconstruction of contents in each of these areas. Imagination, expectations and anticipations of the future and memories are the more active manifestations of this process. In this process mimesis plays an important role. Mimesis is the imitation of reality in play, story-telling or creating images of how things should look like in the future. Through mimesis people can anticipate on roles in social life, or appropriate experiences from someone else and relate them to one’s own life story. When this happens the information is related to the self through processes of association and becomes ‘Erfahrung’.

This article aims to gauge students’ perceptions of the Dutch Party for Animals (PvdD) in order to reflect on the political representation of nonhumans (animals). The support for political representation of nonhumans is based on the ethical underpinning of deep ecology; growing recognition of the importance of sustainability; and increased societal support for animal rights and welfare. This article reflects on these developments using Bachelor students’ assignments from a Sustainable Business course, which asked them to reflect on the underlying principles of the PvdD. Student assignments indicate that educational efforts targeted at fostering ecological citizenship have a positive effect on the recognition and acceptance of ecocentric values. https://doi.org/10.30560/sdr.v1n1p11 LinkedIn: https://www.linkedin.com/in/helenkopnina/

Research on solving mathematical word problems suggests that students may perform better on problems with a close to real-life representation of the problem situation than on word problems. In this study we pursued real-life representation by a mainly depictive representation of the problem situation, mostly by photographs. The prediction that students perform better on problems with a depictive representation of the problem situation than on comparable word problems was tested in a randomised controlled trial with 31,842 students, aged 10–20 years, from primary and secondary education. The conclusion was that students scored significantly higher on problems with a depictive representation of the problem situation, but with a very small effect size of Cohen’s d = 0.09. The results of this research are likely to be relevant for evaluations of mathematics education where word problems are used to evaluate the mathematical capacity of students.

The authors present a general argument for the political representation of non-humans that sits under the broad umbrella of ecocentrism but that does not rely on one specific non-anthropocentric ethical theory. As such, they hope to help move the debate towards a consensus on the need for such political representation. The argument itself has two main prongs. The first is an empirical one: It has the potential to give more effective representation of non-human interests than the alternative of simply having those interests accounted for through internalization within human needs and wishes. The second combines empirical and normative elements: It can add to the development of Earth jurisprudence by envisioning political decision-making processes that are broadly inclusive, so that the protection of non-human interests does not rely solely on legal protection in terms of, for example, tools employed during court hearings on a case-by-case basis. Two illustrative examples are presented, and the work of the the Global Ecocentric Network for Implementing Ecodemocracy (GENIE) is introduced. LinkedIn: https://www.linkedin.com/in/helenkopnina/

In mobile robotics, LASER scanners have a wide spectrum of indoor and outdoor applications, both in structured and unstructured environments, due to their accuracy and precision. Most works that use this sensor have their own data representation and their own case-specific modeling strategies, and no common formalism is adopted. To address this issue, this manuscript presents an analytical approach for the identification and localization of objects using 2D LiDARs. Our main contribution lies in formally defining LASER sensor measurements and their representation, the identification of objects, their main properties, and their location in a scene. We validate our proposal with experiments in generic semi-structured environments common in autonomous navigation, and we demonstrate its feasibility in multiple object detection and identification, strictly following its analytical representation. Finally, our proposal further encourages and facilitates the design, modeling, and implementation of other applications that use LASER scanners as a distance sensor.

We investigate a computer supported approach in which pairs co-con-struct a qualitative representation of the dynamics of the industrial revolution in a shared workspace. A key feature of this approach concerns the use of a meta-vocabulary for representing cause-and-effect relationships that facilitates the use of a predefined norm-representation to automatically steer the collaborative learning process. In particular, it provides focus on the set of ingredients that the learners should use. Additionally, the workspace offers each learner pair information about progress and content-related support. An evaluation study was executed in a real classroom. A workbook provided information for constructing the representation and gave advise on how to approach this task together. How-ever, most pairs took an alternative approach and divided their actions in the shared workspace in an unbalanced way. Three types of task division occurred that showed differences in the number of errors and the number of requests for support. From this result, we formulate future directions for the development of a pedagogical approach that stimulates collaborative learning with qualitative representations and the support offered by the software.
