The purpose of this paper is to cumulate published empirical studies (1980-2009) on the relationship between individual variables and entrepreneurial status. The authors categorize repeatedly analyzed determinants into six perspectives (trait, cognitive, affective, intentions, learning, and economic), review empirical findings for each determinant and each perspective, investigate trends in the field, and propose avenues for future research.

The authors categorize determinants into one of the six paradigms and review findings for 46 repeatedly studied variables from 131 studies. Support for each variable, publication outlets chosen, and temporal trends in exploring entrepreneurial intentions, entrepreneurial status or differences between entrepreneurs and other individuals are analyzed.

Prior studies have focused on trait and economic perspectives with strong support, followed by the learning and intentions perspectives. The affective perspective is a still under-researched, yet growing field. Most articles were published in the 1990s. The emphasis on theoretical perspectives varies over decades. Directions for future research include integrating the perspectives (e.g. across the cognitive and affective domain), testing the temporal stability of influences, and developing and testing cross-level models that incorporate contextual influences.

The paper complements prior reviews and meta-analyses by picturing the breadth of the field and adding important points to the research agenda.

The purpose of this paper is to explore and replicate the indirect effect of smartphone brand tribalism on purchase intent via brand pride and brand attitude.

Using survey data from 190 US (Study 1) and 432 Qatari (Study 2) smartphone consumers, path analysis is used to evaluate the hypotheses.

For these disparate samples, only the defense of the tribal brand dimension of brand tribalism influences brand pride, which in turn leads to a sequential process of brand attitude and purchase intention.

Using only smartphone data from the USA and Qatar may hinder external validity. As effect sizes in this context are understood, researchers have additional benchmarks for future brand tribalism and brand pride research.

The psychological underpinning and presence of brand tribes in society cannot be overlooked by strategists. Such tribal-laden following is too evident within smartphone communities. By further understanding the effect of brand tribalism on brand pride and subsequent attitudinal response and behavioral intent, marketers and brand leaders are in an improved position to develop strategies that appeal to targeted customers, ultimately growing and strengthening their brand value.

Supported by the anthropological view of brand tribalism, this paper contributes to the branding literature by examining the indirect effect of brand tribalism on purchase intention via brand pride and brand attitude. The posited model, previously untested and replicated here across two ethnically diverse samples, shows more explanatory power for defense of the tribal brand on brand pride as compared to the other brand tribalism dimensions. A novel and valid, multi-item brand pride measure is also developed.

Nobody concerned with political economy can neglect the history of economic doctrines. Structural changes in the economy and society influence economic thinking and, conversely, innovative thought structures and attitudes have almost always forced economic institutions and modes of behaviour to adjust. We learn from the history of economic doctrines how a particular theory emerged and whether, and in which environment, it could take root. We can see how a school evolves out of a common methodological perception and similar techniques of analysis, and how it has to establish itself. The interaction between unresolved problems on the one hand, and the search for better solutions or explanations on the other, leads to a change in paradigma and to the formation of new lines of reasoning. As long as the real world is subject to progress and change scientific search for explanation must out of necessity continue.

Germany has a polycentric city structure. This paper aims to reduce complexity of this structure and to find a reliable classification scheme of German housing markets at city level based on 17 relevant market parameters.

This paper uses a two-step clustering algorithm combining k-means with Ward’s method to develop the classification scheme. The clustering process is preceded by a principal component analysis to merely retain the most important dimensions of the market parameters. The robustness of the results is investigated with a bootstrapping method.

It is found that German residential markets can best be segmented into four groups. Geographic contiguity plays a specific role, but is not a main factor. Our bootstrapping analysis identifies the majority of pairwise city relations (88.5%) to be non-random.

A deeper discussion concerning the most relevant market parameters is required. The stability of the clusters is to be re-investigated in the future, as the bootstrapping analysis indicates that some clusters are more homogeneous than others.

The developed classification scheme provides insights into opportunities and risks associated with specific city groups. The findings of this study can be used in portfolio management to reduce unsystematic investment risks and to formulate investment strategies.

To the best of the authors’ knowledge, this is the first paper to offer insights into the German housing markets which applies principal component, cluster and bootstrapping analyses in a sole integrated approach.

A collection of essays by a social economist seeking to balance economics as a science of means with the values deemed necessary to man′s finding the good life and society enduring as a civilized instrumentality. Looks for authority to great men of the past and to today′s moral philosopher: man is an ethical animal. The 13 essays are: 1. Evolutionary Economics: The End of It All? which challenges the view that Darwinism destroyed belief in a universe of purpose and design; 2. Schmoller′s Political Economy: Its Psychic, Moral and Legal Foundations, which centres on the belief that time‐honoured ethical values prevail in an economy formed by ties of common sentiment, ideas, customs and laws; 3. Adam Smith by Gustav von Schmoller – Schmoller rejects Smith′s natural law and sees him as simply spreading the message of Calvinism; 4. Pierre‐Joseph Proudhon, Socialist – Karl Marx, Communist: A Comparison; 5. Marxism and the Instauration of Man, which raises the question for Marx: is the flowering of the new man in Communist society the ultimate end to the dialectical movement of history?; 6. Ethical Progress and Economic Growth in Western Civilization; 7. Ethical Principles in American Society: An Appraisal; 8. The Ugent Need for a Consensus on Moral Values, which focuses on the real dangers inherent in there being no consensus on moral values; 9. Human Resources and the Good Society – man is not to be treated as an economic resource; man′s moral and material wellbeing is the goal; 10. The Social Economist on the Modern Dilemma: Ethical Dwarfs and Nuclear Giants, which argues that it is imperative to distinguish good from evil and to act accordingly: existentialism, situation ethics and evolutionary ethics savour of nihilism; 11. Ethical Principles: The Economist′s Quandary, which is the difficulty of balancing the claims of disinterested science and of the urge to better the human condition; 12. The Role of Government in the Advancement of Cultural Values, which discusses censorship and the funding of art against the background of the US Helms Amendment; 13. Man at the Crossroads draws earlier themes together; the author makes the case for rejecting determinism and the “operant conditioning” of the Skinner school in favour of the moral progress of autonomous man through adherence to traditional ethical values.

Entrepreneurs can easily slide into severe economic crises (Fichman and Levinthal, 1991), in particular in the first years after founding. Additionally, research shows that entrepreneurs often lack a realistic evaluation of the entrepreneurial risks and barriers. Referring to research on cognitive and networked expertise (Ericsson et al., 2006; Hakkarainen et al., 2004), recognising and reflecting on potential failure may help to prevent or manage upcoming crises (Mitchell et al., 2008). Thus, this paper aims to test whether assessing upcoming crises in a new venture varies along with the level of entrepreneurial expertise.

In a cross-sectional design with three subgroups (start-up consultants, entrepreneurs and students), this study evaluated critical incidents that have already been validated as likely to emerge in the post-formation phase (Heinrichs and Jäcklin, 2017). Entrepreneurial expertise was measured by seven indicators, chosen based on the approaches of cognitive and networked expertise.

By applying latent profile analyses, the participants were grouped along these indicators of expertise in three levels. Analysis of variance showed significant differences among the profiles in perceiving critical incidents. Experts rated the incidents significantly higher than semi-experts and novices towards indicating financial risks (medium effect) and the probability that the entrepreneur could manage the upcoming crises (large effect).

The results call for developing and evaluating interventions, e.g. case-oriented entrepreneurship education courses (Heinrichs, 2016), that foster future entrepreneurs’ expertise in perceiving and managing entrepreneurial risks to prevent entrepreneurial failure.

Many Web 2.0 services (including Library 2.0 catalogs) make use of folksonomies. The purpose of this paper is to cut off all tags in the long tail of a document‐specific tag distribution. The remaining tags at the beginning of a tag distribution are considered power tags and form a new, additional search option in information retrieval systems.

In a theoretical approach the paper discusses document‐specific tag distributions (power law and inverse‐logistic shape), the development of such distributions (Yule‐Simon process and shuffling theory) and introduces search tags (besides the well‐known index tags) as a possibility for generating tag distributions.

Search tags are compatible with broad and narrow folksonomies and with all knowledge organization systems (e.g. classification systems and thesauri), while index tags are only applicable in broad folksonomies. Based on these findings, the paper presents a sketch of an algorithm for mining and processing power tags in information retrieval systems.

This conceptual approach is in need of empirical evaluation in a concrete retrieval system.

Power tags are a new search option for retrieval systems to limit the amount of hits.

The paper introduces power tags as a means for enhancing the precision of search results in information retrieval systems that apply folksonomies, e.g. catalogs in Library 2.0 environments.

This article sets out to investigate the relationship between performance management systems (PMSs) and knowledge in public universities. In particular, this paper intends to verify how different choices related to PMS affect the nature of knowledge, in terms of the well‐known tacit vs explicit dichotomy.

The empirical focus is on the recent PMS changes that have been developing in the “modernisation agenda” of the Italian public sector. In particular, 15 case studies of PMS design in Italian universities are presented. The interpretation of the results is based on the Simon's theoretical framework related to the four levers of control.

Results show how PMSs (in the different forms presented in the universities’ evaluation plans) could represent an important social tool to facilitate the management of organizational knowledge, combining explicit and tacit forms of knowledge.

This paper tackles a topic neglected in the knowledge management literature, aiming to open up a discussion on the possible interconnections between PMSs and knowledge in the public arena.

Adverse childhood experiences (ACEs) are a broad conceptual framework in the social sciences that have only recently been studied within criminology. The purpose of this paper is to utilize this framework by applying it to one of the most potentially dangerous forensic populations.

Archival data from 225 federal sex offenders was used to perform descriptive, correlational, and negative binomial regression models.

There was substantial evidence of ACEs including father abandonment/neglect (36 percent), physical abuse (nearly 28 percent), verbal/emotional abuse (more than 24 percent), and sexual abuse (approximately 27 percent). The mean age of sexual victimization was 7.6 years with the youngest age of victimization occurring at the age of 3. Offenders averaged nearly five paraphilias, the most common were pedophilia (57 percent), pornography addiction (43 percent), paraphilia not otherwise specified (35 percent), exhibitionism (26 percent), and voyeurism (21 percent). The offenders averaged 4.7 paraphilias and the range was substantial (0 to 19). Negative binomial regression models indicated that sexual sadism was positively and pornography addiction was negatively associated with serious criminal violence. Offenders with early age of arrest onset and more total arrest charges were more likely to perpetrate kidnaping, rape, and murder.

ACEs are common in the life history of federal sex offenders, but have differential associations with the most serious forms of crime.
