Recognition of non-binary and transgender people in the Dutch pension system

Presenters: Fransje van den Bosch, Inge Bleijenbergh

In recent years, gender identity has become a much-discussed topic in the media and politics. Gender interacts with but is different from sex (World Health Organization, n.d.-a). Sex refers to the biological attributes of humans and gender refers to the socially constructed roles and describes how someone feels about their own body (Canadian Institutes of Health Research, 2020). In 2020, the World HealthOrganization acknowledged a possible difference that individuals may experience in their gender and birth sex. Until 2019, gender incongruence, which indicates a difference between gender and sex, was classified as a mental health disorder in the international Statistical Classification of Diseases and Related Health problems (World Health Organization, n.d.-b). Human Right Watch stated the change had a ‘liberating effect worldwide’ (BBC, 2019). Although non-binaries and transgenders are recognized by the World Health Organization, the Dutch government still only uses the two binary genders ‘male’ and ‘female’ when registering citizenship and registering participants of a pension fund (Rijksoverheid, 2022). Thereby failing to recognize the gender identities non- binary and transgender poeple, who are an estimated 4% of the population. This research aims to contribute to the recognition of non-binary and transgender people within society by examining how pension funds recognize them in the Dutch pension system.

Modeling Public Transportation Attractiveness in System Dynamics: The Significance of Safety Perception

Presenters: Anna R. Siemer, Jefferson K. Rajah

The perception of safety while using public transit is a neglected influence on ridership in most system dynamics transit models. With a preliminary conceptual model, we show how safety perception could be integrated into public transit models. We modeled safety perception as a function of internal safety measures as well as the external social environ-ment that the transit system is embedded in. Potential perceived safety then influences the attractiveness of public trans-it, on top of the typical convenience factors found in existing models. The model is sensitive to changes in both indica-tors of safety perception, confirming the importance of these factors. Therefore, we contend that including these factors improves the conceptualization of public transit attractiveness, which leads to a better understanding of possible policies to increase ridership. Nevertheless, the conceptual model presented here is highly simplified and is preliminary. We further discuss opportunities for future directions in public transit modeling for including safety perception.

Harassment at universities in Bogotá

Presenters: Nicolle Juliana Gracia Santacruz, Liceth Dayana Sarmiento Jimenez, Laura Orozco

This document develops the analysis of the problem of sexual harassment in universities in Bogotá from the perspective of industrial engineering. This study is carried out under the system dynamics tool; and it is done with the purpose of formulating policies to mitigate this problem by modeling and analyzing the social system involved through a model of stocks and flows. Currently, the research is in process through the collection of information with interviews, to carry out the respective development of the diagram of causal cycles and subsequently the model of stocks and flows.

The Kaleidoscope Restaurant: A Multi-perspective view of a complex system

Presenters: Laura Upegui, Mariana Upegui

This paper proposes a System Dynamics model of a restaurant system that integrates the perspectives of multiple actors, allowing for a comprehensive understanding of the system's behavior and the identification of areas where interventions can improve performance. This work highlights the importance of relationships within the system and proposes the development of smaller models for each actor, each with a different color, to explain their decision-making processes, goals, and perceived restrictions. Then, the whole system is shown as a multi-colored model. The goal is to provide valuable insights for restaurant managers and policymakers seeking to improve the performance of their systems, and the insights derived from this model can be extended to other systems and industries for the development of more comprehensive and accurate models.

Causal Loop Diagrams for Understanding Issues in Collaborative Decision-Making of Urban Greenspace Regeneration

Presenters: Yuhong Wang, Nici Zimmermann

Urban greenspace regeneration has become a growing trend worldwide to improve residents’ well-being and quality of life. Collaborative decision-making is needed to deliver to accommodate and sustain common benefits among multiple stakeholders. However, integrating collaboration into mainstream practices is complex and hindered by multiple socio-institutional factors. This study aims to reveal the cause-and-effect chains within key issues related to collaborative decision-making from the perspective of stakeholders' perceptions. The study uses a multi-step methodology, including qualitative research, social network analysis, and a system dynamics approach. This study contributes to the understanding of issues related to collaborative decision-making for urban greenspace regeneration from both holistic and local perspectives.

Solar Energy Transition: Are we Shifting the Burden?

Presenter: Henri Contor

As one may see the environmental crisis as human civilization’s greatest challenge yet, the underlying climate crisis receives more and more attention from the general public. The well known link between energy and climate has lead society to look towards renewable energies. Society has put great hopes and expectations in solar and wind energies in the electric future, which serves as the main focus of this paper. In order to build solar panels, humans use considerable quantities of fossil fuels in the different phases of manufacturing, operating and decommissioning. Isn’t it a paradox to transition our electricity system towards cleaner energies by using fossil fuels? Are we just shifting the burden? The present paper analyses this dynamic with a System Dynamics approach through the understanding of the fundamental causal relationships at hand and the development of scenarios. Findings are unequivocal: emissions from producing solar energy capital are insignificant compared to the emissions that come from producing the total electricity. Moreover, technological improvement cannot solve the issue on its own. Energy demand needs to reduce, regardless of the technological change or climate objectives won’t be met.
