This article aims to examine whether specific job tasks measured at the individual level or personality traits are associated with wages and whether the relationship between personality traits and wages differs depending on the job tasks that individuals perform.

This study analyzes the association between job tasks and personality traits, and their interaction, with regard to wages using German employee data from 2017/2018.

Results suggest that nonroutine manual, interactive or analytic tasks are associated with significantly higher wages compared to routine manual tasks, and while extraversion and emotional stability are related to higher wages, agreeableness and openness tend to be associated with lower wages also within occupations. Moreover, the association between personality traits and wages varies depending on the job task requirements at the workplace. A high degree of extraversion in particular is associated with higher wages when the employee performs nonroutine manual, interactive or analytic tasks.

To date, especially the interaction between individual job tasks and personality traits on wages has not been extensively studied because data on both job tasks and personality at the employee level are scarce. This study contributes to the understanding of wage differences among employees.

Entrepreneurship, Money, and Coordination begins with a single page introduction by the editor, Jurgen Backhaus, a well known economist now at the University of Erfurt, in which we learn that the contribution by Horst Feldmann (Hayek's theory of cultural evolution: A critique of the critiques) provided the impetus for the book's remaining six chapters, a mélange of papers by Brian J. Loasby,¹ Jurgen G. Backhaus, Christian Schubert, Alexander Ebner, Martin T. Bohl and Jens Holscher, and Walter W. Heering. Unfortunately, the papers assembled here do not cohere well and in some instances are not altogether “reader-friendly.” The papers by Bohl and Holscher (a six-page overview and econometric analysis of Hayek's theory of competing currencies) and Heering (on monetary theory) seem rather disconnected from the main theme of the book. Surprisingly, Backhaus’ “Introduction” does not provide a useful integrating overview of the book's subject matter and papers, something readers surely would have appreciated from so eminent a scholar.

Due to the important role of orthography in society, the project called IDeRBlog presented in this paper created a web-based tool to motivate pupils to write text as well as to read and to comment on texts written by fellow students. In addition, IDeRBlog aims to improve student’s German orthography skills and supports teachers and parents with training materials for their students. The paper aims to discuss these issues.

With the aid of learning analytics, the submitted text is analyzed and special feedback is given to the students so that they can try to correct the misspelled words themselves. The teachers as well as the parents are benefiting from the analysis and exercises suggested by the system.

A recent study showed the efficiency of the system in form of an improvement of the students’ orthographic skills. Over a period of four months 70 percent of the students achieved a significant reduction of their spelling mistakes.

IDeRBlog is an innovative approach to improving orthography skills combining blogging and new media with writing and practice.

This paper aims to address the influence of diamond-like carbon (DLC) coatings on the frictional power loss of spur gears. It shows potentials for friction and bulk temperature reduction in industrial use. From a scientific point of view, the thermal insulation effect on fluid friction is addressed, which lowers viscosity in the gear contact due to increasing contact temperature.

Thermal insulation effect is analyzed in detail by means of the heat balance and micro thermal network of thermal elastohydrodynamic lubrication contacts. Preliminary results at a twin-disk test rig are summarized to categorize friction and bulk temperature reduction by DLC coatings. Based on experiments at a gear efficiency test rig, the frictional power losses and bulk temperatures of DLC-coated gears are investigated, whereby load, speed, oil temperature and coatings are varied.

Experimental investigations at the gear efficiency test rig showed friction and bulk temperature reduction for all operating conditions of DLC-coated gears compared to uncoated gears. This effect was most pronounced for high load and high speed. A reduction of the mean gear coefficient of friction on average 25% and maximum 55% was found. A maximum reduction of bulk temperature of 15% was observed.

DLC-coated gears show a high potential for reducing friction and improving load-carrying capacity. However, the industrial implementation is restrained by the limited durability of coatings on gear flanks. Therefore, a further and overall consideration of key durability factors such as substrate material, pretreatment, coating parameters and gear geometry is necessary.

Thermal insulation effect of DLC coatings was shown by theoretical analyses and experimental investigations at model test rigs. Although trial tests on gears were conducted in literature, this study proves the friction reduction by DLC-coated gears for the first time systematically in terms of various operating conditions and coatings.

This paper aims to address the coating and compound analysis of diamond-like carbon (DLC) on steel, to understand the frictional behavior in tribological gear systems presented in paper Part I. Here, the Ti and Zr modified DLC coating architectures are analyzed regarding their chemical, mechanical and thermophysical properties. The results represent a systematic analysis of the thermal insulating effect in tribological contact of DLC coated gears.

The approach was to evaluate the effect of the substitution of Zr through Ti at the reference coating ZrCg to TiCg and the effect on thermophysical properties. Furthermore, the influence of different carbon and hydrogen contents on the coating and compound properties was analyzed. Therefore, different discrete Ti or Zr containing DLC coatings were deposited on an industrial coating machine. Thereby the understanding of the microstructure and chemical composition of the reference coatings is increased.

Results prove comparable mechanical properties of metal modified DLC independent of differences in chemical compositions. Moreover, the compound adhesion between TiC_g/16MnCr5E was improved compared to ZrC_g/16MnCr5E. The effect of hydrogen content Ψ and carbon content x_c on the thermophysical properties is limited by Ψ = 18 at.% and x_c = 90 at.%.

The findings of the combined papers Part I and II show a high potential for industrial application of DLC on gears. Based on the results DLC coatings and gears can be tailored to each other.

Systematic analysis of DLC coatings were conducted to evaluate the effect of titanium, carbon and hydrogen on thermophysical properties.

This paper suggests that an adequate understanding of the notion of the social market economy, which has become a prominent aspect of debates on the social model of the European Constitution, is to be assessed in the context of the historist tradition in German economic and social thought.

The paper explores the intellectual history of the notion of the social market economy and its conceptual relevance for a dynamic European social model by highlighting Alfred Müller‐Armack's contributions to ordoliberalism and their relationship with German historism, in particular with Gustav von Schmoller's approach to Socialpolitik.

The paper finds that the decisive concern of the notion of the social market economy is the reconciliation of economic dynamism and social cohesion in a basic setting of legal rules and cultural values, reaching beyond common interpretations that focus more narrowly on institutional aspects of social policy.

By highlighting the interplay of economic, social and cultural dimensions, the paper suggests an extension of the conceptual horizon of current debates on the social model of the European Union, promoting policy implications that account for the possibilities of balancing conflicting social interests in the process of integration.

The paper applies a reconstruction of the intellectual history of the notion of the social market economy to the problem of designing a social order for the European Union with its underlying discourse on the constitutional status of a European social market economy.

This article starts from the assumption that economic sociology, including Karl Polanyi’s work, can contribute fresh perspectives to regulation debates because it opens up new understandings of the nature of economic activity, a key target of legal regulation. In particular this article examines Polanyi’s idea that society drives regulation. For Polanyi the “regulatory counter-movement” is society’s response to the disembedding – in particular through the proliferation of markets – of economic out of social relationships. Section One of the article identifies three key challenges that arise from this Polanyian take on regulation for contemporary regulation researchers. First, Polanyi focuses on social norms restraining business behavior, but neglects social norms embedded in law as also shaping regulation. Second, he seems to imply a clear-cut conceptual distinction between “economy” and “society.” Third, his analysis sidelines the role of interest politics in the development of regulation.

Addressing the first of these three key challenges, Section Two of this article therefore argues that a Polanyian vision of “socialized” legal regulation should build on contemporary accounts of responsive law and regulation, which focus attention on social norms informing legal regulation. Section Three of this article tackles the second key challenge raised by Polanyi’s work for contemporary regulation researchers, that is, how to transcend a modernist perspective of “economy” and “society” as clearly demarcated, distinct fields of social action. It argues that discourse theory is an important alternative theoretical resource. Drawing on Laclau and Mouffe, the article suggests that understanding “economy” and “society” as performed by open and relationally constructed discourses helps to capture interconnections between “economy” and “society” that become particularly visible when we analyze how specific regulatory regimes work at a medium- and small-scale level. These points are further brought to life in Section Four through a discussion of the European Union (EU) regulatory regime for trade in risky, transgenic agricultural products, and in particular the current reform debates about the consideration of the “socioeconomic impacts” of such products.

Negotiations with venture capitalists (VCs) play a crucial role in the entrepreneurial financing process. Habitual entrepreneurs are generally able to secure more venture capital funding and on better deal terms than novices. This study investigates the disparities in negotiation competencies between habitual and novice entrepreneurs during VC funding negotiations.

This study employed a qualitative approach to investigate the variation in negotiation competencies between habitual and novice entrepreneurs, utilizing the negotiation competency model (NCM). The data analysis and interpretation adopted an inductive concept development approach. A total of 21 semi-structured interviews were conducted with seasoned VCs located in Europe, all of whom had actively engaged in funding negotiations with both habitual and novice entrepreneurs.

The findings revealed substantial disparities between novice and habitual entrepreneurs in VC negotiations. Although not all competencies of the NCM exhibited variances, the results indicate three primary dimensions contributing to these differences: expertise, reputation, and negotiation competence.

This study is groundbreaking as it represents one of the earliest empirical investigations into the entrepreneurial negotiation competencies within VC negotiations. The findings endeavor to narrow the gap between novice and habitual entrepreneurs in VC negotiations by pinpointing the distinct variations between these two groups, which hold significant practical implications. Furthermore, this study expands the conceptual framework of the NCM by identifying supplementary competencies within the realm of VC negotiations.
