Tests of additivity in mixed and fixed effect two-way ANOVA models with single sub-class numbers

In variety testing as well as in psychological assessment, the situation occurs that in a two-way ANOVA-type model with only one replication per cell, analysis is done under the assumption of no interaction between the two factors. Tests for this situation are known only for fixed factors and normally distributed outcomes. In the following we will present five additivity tests and apply them to fixed and mixed models and to quantitative as well as to Bernoulli distributed data. We consider their performance via simulation studies with respect to the type-I-risk and power. Furthermore, two new approaches will be presented, one being a modification of Tukey’s test and the other being a new experimental design to test for interactions.     

Return to Education and the Changing Role of Credentials in the Croatian Labor Market

The countries of Central and Eastern Europe experienced a rapid increase of return to education with the advent of the transition. We look at the dynamics of wage premiums in Croatia and estimate how much the return to education has changed between 1996 and 2004 on the basis of labor force survey data. We also extend the paper in order to address additional features of the wage structure, such as non-linearities in the return to education associated with attainment of credentials. We find that contrary to most transition countries, premiums for education in Croatia began to grow only after the mid 1990s. However, by 2004, they reached the levels of premiums found in other transition countries and advanced market economies, thus creating market incentives for investment in education. We also find that major part of this higher rate of return came through higher return to credentials.

Bank Monitoring and Role of Diversification

I present a framework of banking in which banks’ main role is to monitor their borrowers. Within this framework I analyze the benefits of diversification and the threats of systemic risk and inter-bank competition. Diversification improves banks’ monitoring incentives. High systemic risk not only hampers banks’ monitoring incentives, but also makes diversification less effective. I also show that competition lowers monitoring incentives. I match the insights of the analysis with the abundant literature on the role of banks on the asset-side and provide some implications for recent developments in banking.

Gender differences among Czech youth in prejudice towards minorities

Using a large survey of Czech high school students (n?=?1103), aged 15–20 years, this paper explores youth prejudice to a wide range of minority groups (n?=?21) where family, school, and community contexts are taken into account. General Structural Equation Models are used to explore the determinants of prejudice for 21 minorities using a comparative explanatory framework where the focus is gender differences in prejudice to minorities are examined using three social theories: Social Dominance Theory (SDT), the Theory of Gendered Prejudice (TGP), and Gender Role Beliefs (GRB). This research shows that gender plays a strong role in expressing prejudiced attitudes where females express (a) less prejudiced attitudes toward the Roma, black Africans, Gays and those with mental or physical disabilities, and (b) more prejudiced attitudes towards the homeless, Vietnamese, Muslims, and lesbians. This gendered pattern is explained in terms of insights from SDT, TGP, and GRB.     

Digitalisierung der Arbeit: Konsequenzen für Führung und Zusammenarbeit

In this paper, we focus on the characteristics and requirements of digital leadership and cooperation when teams are working on complex and dynamic project tasks, and cooperation is mediated by modern information and communication technology. Based on current research results we discuss the question, whether the thesis can be supported that leadership of complex digital teamwork can only be successful if leadership functions are delegated to the team and personal leadership is complemented by structural leadership. Despite many ambiguous research results regarding the effects of digital leadership current findings seem to support that more shared leadership in self-managing project teams seems to be helpful for team performance.     

The Image of Ottomans in Croatian Historiography: Changing Narratives in Elementary School Textbooks in Croatia—1980s to 2000s

The author analyses the discourse on the Ottomans in Croatian history textbooks during the last decade of Socialist rule in the 1980s, the decade of nationalist revival in the 1990s and the decade of the normalization in 2000s and establishes the connections between dominant Croatian ideologies at that time, the historiography and the textbooks. The history textbooks in Croatia during the socialist period (1945–1990) in Yugoslavia continued the anti-Ottoman narrative defined as late as the end of nineteenth century by Croatian nationalist historiography. The discourse was mainly focused on the allegedly unfavourable economic position of Christians during the Ottoman rule and the common plight of Croats and other Southern Slavs. During the nationalistic period of the Franjo Tu?man regime in the 1990s the discourse in the history textbooks remained negative, concentrating on the damage that was inflicted by Ottoman expansion solely to Croatian nation, the state and Catholic faith. After the nationalist regime of Franjo Tu?man left power in 1999 and liberal democracy was finally introduced, Croatian textbooks started to present the Ottoman conquests in a more neutral language and Ottoman Muslim civilization received more nuanced treatment.     

Public relations and lobbying: New legislation in Slovenia

This article reviews lobbying in the political sciences and public relations literature, and it also provides a conceptualization for the regulatory practices of lobbying around the world. Then, it presents the newest law on lobbying instituted in 2010 in the Republic of Slovenia, the Integrity and Prevention of Corruption Act. This Act treats lobbying in two ways: (1) as a communication technique used by interest groups to privately influence government officials and (2) as a process of access to information by the same interest groups. This inconsistency follows the same trend for lobbying regulation in Europe and raises important questions regarding lobbying practice and regulation. Lobbying is fundamentally a public relations practice exercised in private and public sectors, and it uses direct and indirect communication between interest groups and their respective government.

Policy-making on science in society between Europeanization and core–periphery divide

The aim of the paper is to identify the cross-national differences and similarities in policy-making trends on science in society (SiS) based on the comparative analysis of national reports from FP7 project “Monitoring Policy and Research Activities Related to Science in Society in Europe”. Science in society in EU is characterized by two parallel processes: Europeanization and diversity of science and innovation policies. The focus of the analysis is to explore the possible indications of Europeanization as well as diversities and find elements of certain elements of core–periphery model. The focus of the analysis is to explore the existence of common issues of SiS and on the other side different policy actions and national priorities. Although the analysis reveals the presence of Europeanization process diversities and divides are still present which draws attention to a core–periphery model. While common trends can be recognized on the theoretical and contextual level mainly coming from the various processes of Europeanization, the core–periphery model is simultaneously present on the practical level of governance and policy-making.     

Independent inventors,social capital,and knowledge transfer – the case of Slovenia

This paper explores the role and significance of independent inventors within the national innovation system. By using a case study based on interviews with 22 independent inventors, it examines the types of social capital facilitating independent inventors' access to relevant knowledge and information. The findings show that, in line with their marginalization in the national innovation system, independent inventors have very limited access to the services and assistance of supportive organizations of the national innovation system. They primarily rely on the social capital residing in civil society organizations as well as the social capital of their family and friends. Professional and interdisciplinary linkages can thus be regarded as their weak point hindering their access to relevant knowledge and information.
