Algorithm for fast evaluation of in-plane fiber orientation in reinforced plastics using light microscopy images
(2023-09-26)
Methods for evaluating the orientation of carbon fibers in reinforced plastics vary in complexity and are application specific. Here, we report an algorithm that quickly evaluates in-plane fiber orientation based on determining the correlation coefficient of adjacent regions in microscopy images. The result is not the fiber orientation of individual fibers, but the principal fiber orientation of small image areas. This method is applicable to large areas due to its low computation time and captures varying fiber ...

Embedding plural values in value chains to enhance sustainability in the management of cork oak landscapes
(2023-07-19)
Context
The management of Portuguese agroforestry landscapes is currently focused on specialised cork and cattle production. Sustainable landscape management is increasingly discussed as an effective option to foster the multifunctionality of these landscapes. Such management requires consideration of multiple values connected to the landscape and to the products stemming from it.
Objectives
The aim of this study is to (1) assess the importance of specific values related to cork and to the cork production ...

Multilingualism is associated with small task-specific advantages in cognitive performance of older adults
(2023-10-07)
The protective effects of multiple language knowledge on the maintenance of cognitive functions in older adults have been discussed controversially, among others, because of methodological inconsistencies between studies. In a sample of N = 528 German monolinguals and multilinguals (speaking two or more languages) older than 60 years, this study examined (1) whether speaking multiple languages is positively related to performance on tasks of interference suppression, working memory, concept shifting, and phonemic and ...

Inside the world of stepsiblings: Linking global production networks to sustainable supply chain management
(2023-07-31)
The theoretical foundation of (sustainable) supply chain management (SSCM) is an issue of frequent debate. Integrating it with the Global Production Networks (GPN), which is a kind of stepsibling, can help expanding the theoretical foundations of SSCM. The purpose of this paper is to explore how the GPN approach links to SSCM in analysing and explaining interorganizational sustainability. This paper is conceptual. Five central GPN constructs are identified: (1) the emerging supply chain structures and sustainability; ...

The role of prior knowledge and need for cognition for the effectiveness of interleaved and blocked practice
(2023-07-11)
Interleaved practice combined with comparison prompts can better foster students’ adaptive use of subtraction strategies compared to blocked practice. It has not been previously investigated whether all students benefit equally from these teaching approaches. While interleaving subtraction tasks prompts students’ attention to the different task characteristics triggering the use of specific subtraction strategies, blocked practice does not support students in detecting these differences. Thus, low-prior-knowledge ...

Conditions and Effects of Norm Internalization
(2023-01-31)
Norm internalization refers to the process of adoption of normative beliefs by individuals, thus representing a link between individual and social change. However, there are several questions regarding norm internalization which need to be answered. These include understanding under which circumstances norm internalization does occur by considering the effects of internalizing either a certain norm or even conflicting norms. To investigate the conditions and effects of norm internalization, we developed a theoretical ...

Dynamic tensile deformation behavior of AISI 316L stainless steel fabricated by laser-beam directed energy deposition
(2023-11-07)
The dynamic deformation behavior of metallic materials is the key to crash-safe design in many applications, e.g., in the automotive sector. However, in the field of additive manufacturing, dynamic deformation properties have only been scarcely studied. Based on the intrinsic interrelationships of process parameters, post-process heat treatments and the resulting microstructure, the present study seeks to provide a holistic overview of the dynamic tensile deformation properties of AISI 316L stainless steel, fabricated ...

Boundary Work Tactics and Their Effects on Information and Communication Technology Use After Hours and Recovery
(2023-10-16)
With an increasing use of work-related technologies after hours and mobile working, boundaries between work and personal life domains blur more and more, impairing recovery. Qualitative studies have shown that individuals use various boundary work tactics to actively manage their work–nonwork boundaries. However, it remains largely unknown how the use of such tactics contributes to recovery. This research differentiates types of availability-related boundary work tactics and organizes them according to their underlying ...

“Stop crying your heart out”: how failed founders can use emotional failure narratives
(2023-06-07)
Failed founders experience very intense emotions resulting from their entrepreneurial failure. Since many founders are not discouraged by failure and consider founding a subsequent startup, the need to deal with the stigma attached to failed founders. Applying an experimental research design, this study investigates how failed founders can use emotional failure narratives to approach potential co-founders for their subsequent venture project. We demonstrate that the use of failure narratives that contain both negative ...

Small villages and their sanitary infrastructure—an unnoticed influence on water quantity and a threat to water quality in headwater catchments
(2023-11-16)
In rural catchments, villages often feature their own, separate urban water infrastructure, including combined sewer overflows (CSOs) or wastewater treatment plants (WWTPs). These point sources affect the water quantity and quality of the receiving low order streams. However, the extent of this impact is rarely monitored. We installed discharge and water quality measurements at the outlet of two small, neighbouring headwater catchments, one that includes a village, a WWTP, and two CSOs, while the other is predominantly ...
