ESG Disclosure and Idiosyncratic Risk in Initial Public Offerings
(2021-06-01)
Although legitimacy theory provides strong arguments that environmental, social and governance (ESG) disclosure and performance can help mitigate firm-specific (idiosyncratic) risks, this relationship has been repeatedly challenged by conceptual arguments, such as ‘transparency fallacy’ or ‘impression management’, and mixed empirical evidence. Therefore, we investigate this relationship in the revelatory case of initial public offerings (IPOs), which represent the first sale of common stock to the wider public. IPOs ...

Balancing Trade-Offs in Milk Production by Making Use of Animal Individual Energy Balancing
(2022-05-17)
Traditionally, the energy supply of dairy cows is based on the average performance of the herd. Because this contradicts the great variation in requirements between individual animals, the objective of the present study was to quantify both the extent and consequences of variation in the relevant sub-variables used to calculate the energy balance (EB) on an individual animal basis. Total energy supply (TES) and requirements (TER) of 28 multiparous German Holstein dairy cows fed TMR with 7.0 MJ NEL were studied between ...

The many faces of Post-Development: alternatives to development in Tanzania, Iran and Haiti
(2022-06-21)
Post-Development, a body of transitional imaginaries, is not homogenous, neither in its critique, nor in the alternatives proposed. Given that the term ‘development’ is already highly contentious, the question of what ‘alternatives to development’ might be, becomes difficult to respond to. In this article, we argue that Post-Development can assume many faces that are highly dependent upon their conceptual and geographical contexts. In analysing practices of resistance, contestation and subversion in Tanzania, Iran ...

Should I Stay or Should I Go? Risk Perception and Use of Local Public Transport During the COVID-19 Pandemic
(2022-07-07)
In light of the climate crisis, the transport sector needs to be urgently transformed and the number of users of local public transport needs to be increased. However, the first year of the COVID-19 pandemic severely affected public transport with passenger numbers declining up to 80% in Germany. In addition to a general decrease in mobility during lockdowns, we can observe a shift in decision-making in regards to modes of transportation, with public transport losing out. We argue that this change in behavior can be ...

Virtual Reality Experience of Mega Sports Events: A Technology Acceptance Study
(2022-05-24)
Digitalization has advanced to become an opportunity to spectate sports during the pandemic and its restrictions for traveling to competitions. The purpose of this study is to investigate the antecedents of using virtual reality technology for spectating mega sports events. Based on a literature review, the authors created a model of behavioral intention, built on the unified theory of acceptance and use of technology and technology acceptance model to examine the curiosity and self-construal of spectators. An online ...

Determination of Local Electrical Properties Using a Potential Field Measurement for Electrically Conductive Carbon Fiber Reinforced Plastics with Metal Contact Pins Joined via Injection Molding
(2022-07-09)
Carbon fiber reinforced plastics (CFRP) bear a high potential in terms of electrical conductivity and its potential applications. A locally resolved electrical measurement method for these anisotropic materials is a key prerequisite for understanding the structural and manufacturing process-related interrelationships. The aim of this paper is to develop a measurement method that allows this to be achieved and also to investigate areas of overmolded metal contact pins in detail. CFRP samples with polyamide 6 and ...

Botanical concrete
(2022-06-30)
La ricerca sul Botanical Concrete indaga con un approccio innovativo, basato sul design thinking, i materiali e la fitotecnologia, nei sistemi di inverdimento per pareti al fine di dare nuove funzioni al calcestruzzo e consentire l’insediamento superficiale permanente contemporaneamente di crittogame e tracheofite, due specie con diverse esigenze di substrato che si traducono in due distinti requisiti del calcestruzzo. Dalla combinazione dei risultati delle sperimentazioni sulle crittogame e sulle tracheofite si ...

Enhancement of Weldability at Laser Beam Welding of 22MnB5 by an Entrained Ultrasonic Wave Superposition
(2022-07-09)
In this paper, the potential of directional ultrasonic wave superposition by moving sound generators for laser beam welding of high-strength steel alloys 1.5528 (22MnB5) is studied. Steel sheets of identical thickness and in form of tailored blanks were joined in butt joint configuration. The influences of the various excitation parameters of the moving sound generators on the ultrasonic coupling and their influence on the distribution of the AlSi coating components within the melting zone and the weld seam characteristics ...

Cultural Sensitivity in Preventive Infant Mental Health Care: An Example From the Developmental Guidance Project FIRST STEPS in Belgium
(2022-05-04)
Preventive developmental guidance programmes have been applied on a large scale for several decades now in many western countries. But how do we adapt these programs to families with very different ethnic backgrounds? How can we concretise the concept of cultural sensitivity into that context? The plea of von Klitzing, the former President of the World Association for Infant Mental Health, for further reflection on the concretization of cultural sensitivity in the context of infant mental health care is the main ...

Societal Evaluation of Bioeconomy Scenarios for Germany
(2022-05-05)
Transitioning to a bio-based economy is widely perceived as a necessary way to tackle climate change and other key environmental challenges. Given the major socio-economic consequences that such a transition entails for people’s everyday lives, it is crucial to take account of citizens’ perceptions and levels of acceptance of these changes. This study applies a holistic approach to gain an understanding of how citizens in Germany assess possible developments associated with transitioning to a bioeconomy. We developed ...
