Analyzing the implications of organic standardization and certification in alternative food networks: The capability approach
(2023-06-14)
Although organic standards and certification schemes have a crucial role in ensuring quality, safety, and sustainability within food systems, there is a need to critically analyze their implications on human capabilities within alternative food networks (AFNs). Therefore, this paper draws upon the capability approach to analyze the implications of three governance mechanisms (i.e., third-party, social control, and hybrid certification) on human flourishing within AFNs in Ceará, Brazil. The three cases primarily build ...

Interrupting the neoliberal masculine state machinery? Strategic selectivities and municipalist practice in Barcelona and Zagreb
(2022-07-07)
All municipalist initiatives are confronted with what Marx called the ‘state machinery’: an ensemble of apparatuses protecting the status quo of capitalist accumulation. It is difficult for municipalist movements to sustain their momentum of storming the city halls in the face of this reality. Looking at Barcelona En Comú (Barcelona in Common) and Zagreb Je NAŠ! (Zagreb Is Ours!), the article discusses what experiences municipalist actors gain when inspecting the state machinery close up. We identify the traces they ...

Depression, Race-Based Bias, and Judgements of Veracity
(2023-07-26)
The depressive realism hypothesis suggests that depressed individuals have a more realistic perception than nondepressed. Most studies depict the effects of depressive realism on self-perceptions. However, some lie detection studies suggest the effects of depressive realism on the perception of others. Our study investigated the hypothesis that individuals with subclinical depression levels (dysphoric) show a heightened accuracy in lie detection and a lower truth bias. Furthermore, we expected these effects to be ...

Design to manufacture of fully stressed curved structures through elastic deformation of thin steel sheets with interlocking connections
(2023-09-12)
The research project presents the development of a fully digital design to manufacture process chain for high-performance curved steel elements produced by laser cutting thin steel sheets and assembled through elastic deformation. Although there have been developments in industrial robotic setups to automate steel beam bending, these processes rely on an iterative approach and are time-consuming and costly when there is a need for high accuracy.
The paper shows how the production of tailor-made geometric parts ...

Potentials of reusing steel skeleton structures from multistorey parking units for architectural applications
(2023-09-12)
In the context of urban mining, which aims to extend the value chain of building components to conserve resources, save energy, avoid waste, and reduce emissions, the reuse of structural steel has great potential, that has hardly been exploited to date.
In Germany, a significant amount of steel is found within multistorey parking units. Due to the standardised and mass relevant steel used in these structures and considering their diminishing significance in the context of transportation transitions, these buildings ...

Yield stability of silage maize double cropping systems across nine German environments
(2023-10-19)
Introduction: Yield and its stability are both vital characteristics to evaluate the viability of cropping systems. However, the current frames of field research hardly allow an accurate evaluation of short-term effect stability. Therefore, over nine German environments (three years and three locations), first crop, maize, total harvested dry biomass yield (DMY), and maize dry matter content (DMC) variability were evaluated through a risk assessment in an organically managed silage maize experiment comprising 18 ...

Dissimilar Laser Beam Welding of Titanium to Stainless Steel Using Pure Niobium as Filler Material in Lap Joint Configuration
(2023-09-20)
In the present investigation, commercially pure titanium is welded to AISI 316L stainless steel by intermixing niobium as filler material in a lap joint configuration. For this purpose, a pulsed Nd:YAG laser with various pulse durations and pulse peak powers is employed to obtain different mixing conditions for the materials. It will be demonstrated that, despite the implementation of the filler material, the weld seams are characterized by a high affinity for cracking, which in turn can be attributed to the formation ...

Human‑elephant conflict in the Sri Lankan dry zone: investigating social and geographical drivers through field‑based methods
(2023-07-02)
Human-elephant conflict (HEC) in Sri Lanka has escalated over the recent years, with, on average, 300 elephant deaths annually and human casualties of around 90 per year. Employing field-based qualitative methods, this contribution identifies causes and contexts of human-elephant conflict in those parts of the Sri Lankan dry zone most severely affected. We have used field observations as well as semi-structured interviews with experts and affected villagers as primary data collection techniques. The findings show ...

Relevance of organic vs. inorganic nitrogen in intra- and interspecific competition of seven central European tree species
(2023-06-23)
Key message: When competing for nitrogen with other tree species, organic N is more important than inorganic N for most species. //
Abstract: Competition for nitrogen (N) in the rhizosphere is a key process regulating a seedling´s chances for growth and survival. However, only few studies have investigated this at the individual species´ level when using a community approach. In this study, ¹⁵N incubation experiments were conducted to quantify inorganic (i.e. ammonium and nitrate) and organic (i.e. glutamine-N and ...

Challenges in detecting proximal effects of existential threat on lie detection accuracy
(2022-06-14)
The present work documents our investigation of proximal (i.e., immediate) effects of existential threat on the process of lie detection. Specifically, we hypothesized that lie detection accuracy will be higher in a mortality salience (MS) condition compared with the control condition. In two lab-based studies (N = 120; N = 109) and one internet study (N = 1294), we did not find any evidence for this hypothesis, that is, MS effects on lie detection accuracy were constantly not significant. However, these null findings ...
