The level of trust in a service provider is an important decision factor when buying industrial services. Especially, the outcome uncertainties of services, its individuality, and asymmetric information between buyer and seller are some reasons that the evaluation of trust is a key component in service trading. Consequently, searching of potential new suppliers involves examining providers’ trustworthiness. This paper focuses on the study of online trust signals used by buyers, to assess provider’s trustworthiness in the context of industrial services. The main research objective is to propose the basis for a digital tool, which helps buyers to assess provider’s trustworthiness by providing a “standardized trustworthiness signal description” and “trust functionalities.” A particular approach is used, wherein different methods are mixed such as a case study, expert interviews, and a quantitative method following the guideline of the design science paradigm. The aim is to propose a useful tool for trustworthiness assessment to enhance e-markets for industrial services.

Trust is a crucial element in business exchanges. Trust has been the subject of considerable research. Most prior studies are insensitive to context studies. However, the advent of the extended enterprise with the disintegration of production and innovation processes, the digitalization of interactions, and the increased competition in global markets, among other factors, fundamentally alter the contexts of buyer–supplier relationships. New enriched perspectives and adapted approaches of trust in B-to-B settings are necessary.

This volume addresses new issues showing evidence from advanced, emerging, and developing markets by applying different theoretical and methodological perspectives. The findings lead to identifying consistencies, richness, and distinctiveness of antecedents, processes, and consequences of trust in various B-to-B contexts. It provides suggestions for future research and new levers and guidance for managers to build successful business relationships.

Henryk Grossman was the first person to systematically explore Marx’s explanation of capitalist crises in terms of the tendency for the rate of profit to fall and to place it in the context of the distinction between use and exchange value. His “The Law of Accumulation and Breakdown of the Capitalist System” remains an important reference point in the Marxist literature on economic crises. That literature has been plagued by distortions of Grossman’s position which derive from early hostile reviews of his book. These accused Grossman of a mechanical approach to the end of capitalism and of neglecting factors which boost profit rates. Grossman, in fact, contributed a complementary economic element to the recovery of Marxism undertaken by Lenin (particularly in the area of Marxist politics) and Lukács (in philosophy). In both published and unpublished work, Grossman also dealt with and even anticipated criticisms of his methodology and treatment of countertendencies to the tendency for the rate of profit to fall. Far from being mechanical, his economic analysis can still assist the struggle for working class self-emancipation.

Student interest and learning success is an important component of teaching learning research. However, while the impact of emotions and psychological needs on students' achievements has been a focus of research, the impact of their physiological needs has been under studied. In this explorative study, I examine what impact the physiological and psychological needs of student teachers have on their feelings, motivation, and interest in different learning settings.

The research method used was the daily reconstruction method and included the Felix-App, a new digital research and feedback tool that allows the measurement of feelings, needs, motivation, and interest in real time.

The results suggest the importance of physiological needs for perceived emotions, motivation, and interest in the learning subject. The psychological needs, on the other hand, are of less importance.

The Felix-App is an innovative tool to learn more about learners' emotions and needs in real learning settings. The importance of physiological needs has been known since Maslow, but should be considered much more in the context of teaching and learning research in the future. There is a need for further research on the importance of physical aspects in learning.
