Entwicklungslinien und Herausforderungen der Arbeitsbeziehungen in Deutschland und Hessen
(2024-05)
Vor dem Hintergrund der gegenwärtigen Herausforderungen der Arbeitswelt sowie den ambivalenten Befunden zur Funktionsfähigkeit der Sozialpartnerschaft setzt sich dieser Beitrag – der zur Arbeitsweltberichterstattung Hessen zählt – einerseits mit den Strukturen und Entwicklungen des spezifisch „deutschen Modells“ der Arbeitsbeziehungen auseinander. Andererseits wird danach gefragt, welchen Herausforderungen die sozialpartnerschaftlichen Akteure auf verschiedenen Ebenen gegenüberstehen und ob bzw. wie es ihnen bisher ...

Evaluation of efficacy of homeopathic and antibiotic treatment in scientific research and practice with focus on bovine mastitis
(2024)
The use of homeopathy and antibiotics in treatment have the same goal: to cure a diseased individual. The first choice should be the most effective treatment and only a repeated treatment success will justify its use. If the chosen treatment is not effective, unnecessary suffering of diseased animals, spreading of disease or chronification of mastitis will be the result. Additionally, in case of antibiotic use, an ineffective use will select and promote the prevalence of multi-resistant bacteria in the environment, ...

Fostering sustainable consumption through communication: Consumers’ appreciation of biodiversity-friendly pasture-based cattle husbandry
(2024-01)
Considering dramatic environmental changes, there is an evident necessity of a transition to more sustainable animal production that caters to societal demand for ethical production and consumption. The slow but steady shift in consumer demand for animal-friendly, environmentally, and socially re-sponsible animal products has been well documented over the past years. The overarching goal of this dissertation is to provide insights regarding consumer perceptions, acceptance, preferences and com-munication of ...

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 ...
