How political philosophies can help to discuss and differentiate theories in community ecology
This paper uses structural analogies to competing political philosophies of human society as a heuristic tool to differentiate between ecological theories and to bring out new aspects of apparently well-known classics of ecological scholarship. These two different areas of knowledge have in common that their objects are ‘societies’, i.e. units composed of individuals, and that contradictory and competing theories about these supra-individual units exist. The benefit of discussing ecological theories in terms of their ...
Facilitating business model innovation: The influence of sustainability and the mediating role of strategic orientations
Businesses increasingly incorporate the sustainability aspects into their products, services, and processes that drive innovation. While extant research on the linkage between sustainability and innovation has gained momentum over the past years, prior research has predominantly focused on sustainability's performance impacts (e.g., financially and environmentally) and product innovation outputs, neglecting the internal mechanisms that leverage sustainability. While findings from previous studies suggest that ...
Kötzing, Andreas (Hrsg.): Bilder der Allmacht. Die Staatssicherheit in Film und Fernsehen, 336 S., Wallstein, Göttingen 2018.
Die DDR war nicht gerade ein Staat, der geeignet gewesen wäre, den Glamour Hollywoods anzuziehen. Der Stasi gelang in gewisser Weise allerdings auch dies: Der Mauerbau und die besondere Lage Berlins beflügelten schnell die Fantasien von Filmschaffenden und so entstanden gerade in den 1960er Jahren eine Reihe hochkarätig besetzter Filme, in denen sich etwa Paul Newman („Der zerrissene Vorhang“, 1966) oder Richard Burton („Der Spion, der aus der Kälte kam“, 1965) mit den Machenschaften der Stasi auseinandersetzen ...
Establishing a Sustainable Waste Management System in a Transitional Economic Context: Analysis of the Socio-Economic Dynamics
Establishing a sustainable waste management system concerns multiple aspects of the prospected geo-locations. Among them, the dynamics of the socio-economy play a crucial role. Based on the idea of circular economy (CE), the amount of waste, in general, should be reduced and the process of social involvement is embedded. This study aims to examine the social willingness towards a sustainable waste management system at a local level in Georgia. The research study was conducted with waste management analyses in Marneuli ...
Vehicular Livestock Mobility in West Africa: Seasonal Traffic Flows of Cattle, Sheep, and Goats across Bamako
Mali is a major livestock producing country in West Africa. However, in recent years, the sector has faced multiple challenges like farmer-herder conflicts, overuse of grazing and water resources, and the effects of climate change. Meanwhile, traditional livestock systems are becoming less important given the increased availability of vehicular transport for regional and international animal trade as well as new opportunities for more specialised urban and peri-urban production systems. To assess the role of Mali’s ...
Exploiting ferroelectric and ferroelastic effects in piezoelectric energy harvesting: theoretical studies and parameter optimization
While piezoelectric energy harvesting typically focuses on converting mechanical into electrical energy on the basis of the linear reversible piezoelectric effect, the potential of exploiting the non-linear ferroelectric effect is investigated theoretically in this paper. Due to its dissipative nature, domain switching, on the one hand, is basically avoided in order to prevent mechanical energy from being converted into heat. However, the electrical output, on the other hand, is augmented due to the increased change ...
Articulating Body, Territory, and the Defence of Life: The Politics of Strategic Equivalencing between Women in Anti‐Mining Movements and the Feminist Movement in Peru
In Latin America, rural and indigenous women have mobilised in defence of their territories and built strategic alliances with urban and mestiza feminist movements. This paper focuses on how these processes have played out in Peru, tracing the development of the discourse on ‘body as territory’, which articulates sexual and reproductive rights with territorial autonomy. It discusses the ‘cosmopolitics’ of translating the distinct concerns and worldviews of the women involved, arguing that this discourse has enabled ...
Distributed Practice: Rarely Realized in Self-Regulated Mathematical Learning
The purpose of the present study was to investigate the effect and use of distributed practice in the context of self-regulated mathematical learning in high school. With distributed practice, a fixed learning duration is spread over several sessions, whereas with massed practice, the same time is spent learning in one session. Distributed practice has been proven to be an effective tool for improving long-term retention of verbal material and simple procedural knowledge in mathematics, at least when the practice ...
Micromagnetic Simulations of Submicron Vortex Structures for the Detection of Superparamagnetic Labels
We present a numerical investigation on the detection of superparamagnetic labels using a giant magnetoresistance (GMR) vortex structure. For this purpose, the Landau–Lifshitz–Gilbert equation was solved numerically applying an external z-field for the activation of the superparamagnetic label. Initially, the free layer’s magnetization change due to the stray field of the label is simulated. The electric response of the GMR sensor is calculated by applying a self-consistent spin-diffusion model to the precomputed ...
On the Finite Orthogonality of q-Pseudo-Jacobi Polynomials
Using the Sturm–Liouville theory in q-difference spaces, we prove the finite orthogonality of q-Pseudo Jacobi polynomials. Their norm square values are then explicitly computed by means of the Favard theorem.
