Bringing heterodoxy back into a world of pessimism
(2024-01-29)
In this Extractivism Occasional Papers’ volume, we brought together two first-wave scholars working on structuralism, class and development, Luiz Carlos Bresser-Pereira and Hartmut Elsenhans, and upcoming scholars – Ingrid Harvord Kvangraven, Fernando Rugitsky and Johanna Siebert – who build on structuralist thinking to present their own take on the importance of revitalising it. Our project follows the Hegelian dialectics and seeks aufheben, in the sense of learning from the past, preserving what is valuable, and ...

Searching for a substitute: Algeria and Venezuela as energy security alternatives for Europe?
(2024-01-26)
• Venezuela und Algerien sind für die Europäische Union potenzielle, zukünftige Energiepartner.
• Die EU steht vor einer doppelten Herausforderung: Sie muss kurzfristige Alternativen für Gaslieferungen finden und sich langfristig
einem green deal verpflichten. Dies erfordert einen grundlegenden Wandel der Zusammenarbeit zwischen EU mit ihren
Energielieferländern.
• Algerien verfügt über großes Potenzial erneuerbarer Energien, es mangelt ihnen jedoch an Technologie und Kapital. Eine EUAlgerien
Energiepartnerschäft ...

Twin Basic Quantum Calculus and its Applications
(2024)
We give in this work some results on twin basic quantum calculus. The (p,q)-derivative, the (p,q)-integral and some (p,q)-Taylor formula are discussed. Next, we introduce and provide several results about (p,q)-Gamma and (p,q)-Beta functions. Some (p,q)-Sturm Liouville problems are introduced and some (p,q)-hypergeometric solutions are obtained. The work ends with the introduction (p,q)-Appell polynomials and some (p,q)-Laplace transforms.

Food security status and its determinants: A comparative study between farm households under government and non-government agricultural extension services in Bangladesh
(2024-02-29)
The ability to obtain food security is essential to human existence. Secure food access can have a variety of positive effects, such as economic expansion, the creation of jobs, and the eradication of poverty. This study assessed the food security status of farm households and its determinants in the Dinajpur district of Bangladesh. Efforts were also made to assess and compare the socio-economic demographics and item-wise calorie intake among households receiving government and non-government agricultural extension ...

Reporting Power
(2024)
An eclectic genealogy (Foucault, 1977) that reconstructs the previous understanding and emergence of a ‘taken for granted’ global practice: the practice of suspicious activity reporting. A governance practice whereby financial institutions worldwide document and report the conduct of consumers deemed suspicious. At the center of this practice is a material artefact, a multipage fillable form called the Suspicious Activity Report. Following Actor-Network Theory (Latour, 1987), the form also serves as the centerpiece ...

Influence of deep rolling at different temperatures on near-surface and mechanical properties of a Maraging C250 steel
(2024-04-27)
Due to an outstanding combination of high strength and fracture toughness Maraging steels are used in numerous industries, e.g., in the aerospace sector. The high strength can be attributed to precipitation strengthening by conventional age-hardening heat treatments. However, as many of the envisaged applications will suffer from cyclic loadings, the fatigue properties are of significant interest in terms of a reliable use. Generally, Maraging steels are characterized by a relatively low fatigue strength limiting the ...

Dynamics of Norms in Decision-Making
(2024-01)
So far, there is a lack of understanding how norms change. The aim of the present dissertation was twofold: (1) addressing differences between change processes of different types of norms and (2) focusing more particularly on how norms are internalized. To study norm dynamics, a multi-method approach was chosen, combining theory, social simulation, and experimental research. In the theoretical contribution, a psychologically grounded conceptual model of norm change and decision-making was presented. Based on a refined ...

Working Paper: Modeling Infection Risk in Local Public Transport
(2024)
To model the infection risk in local public transport, additional information on the personal contacts during a trip with local public transport as well as the contact duration with them is necessary. As morning student traffic in local public transport vehicles was assumed to hold a high infection risk during the COVID-19 pandemic, staggered school starting times were tested in the city of Herne in Germany. The data obtained during this time was used to create a calculation tool for the number of personal contacts ...

Climate Change and Consumption Patterns in Latin America: The Urgency of a Structural Transformation
(2024-02)
• Climate change obstructs Latin America's development, affecting the economy, society, and the environment. A substantial investment is needed for the 2050-2070 deep decarbonization process.
• Latin America's unsustainable development in the last five decades has boosted consumption, employment, and poverty reduction but falls short in addressing chronic poverty and high-income concentration. This undermines economic dynamics and exposes society to climate change impacts.
• A just climate transition requires changes ...

A Unifying Theory for Runge-Kutta-like Time Integrators: Convergence and Stability
(2024)
The work deals with two major topics concerning the numerical analysis of Runge-Kutta-like (RK-like) methods, namely their stability and order of convergence. RK-like methods differ from additive RK methods in that their coefficients are allowed to depend on the solution and the step size. As a result of this, we also refer to them as non-standard additive RK (NSARK) methods. We motivate and introduce modified Patankar (MP) schemes as a subclass of NSARK methods and emphasize their importance. The first major part ...
