To enable a better understanding of the underlying logic of path dependence, we set forth a theoretical framework explaining how organizations become path dependent. At its core are the dynamics of self-reinforcing mechanisms, which are likely to lead an organization into a lock-in. By drawing on studies of technological paths, we conceptualize the emergent process of path dependence along three distinct stages. We also use the model to explore breakouts from organizational path dependence and discuss implications for managing and researching organizational paths.

Mindfulness programs for schools are popular. We systematically reviewed the evidence regarding the effects of school-based mindfulness interventions on psychological outcomes, using a comprehensive search strategy designed to locate both published and unpublished studies. Systematic searches in 12 databases were performed in August 2012. Further studies were identified via hand search and contact with experts. Two reviewers independently extracted the data, also selecting information about intervention programs (elements, structure etc.), feasibility, and acceptance. Twenty-four studies were identified, of which 13 were published. Nineteen studies used a controlled design. In total, 1348 students were instructed in mindfulness, with 876 serving as controls, ranging from grade 1 to 12. Overall effect sizes were Hedge's g = 0.40 between groups and g = 0.41 within groups (p < 0.0001). Between group effect sizes for domains were: cognitive performance g = 0.80, stress g = 0.39, resilience g = 0.36, (all p < 0.05), emotional problems g = 0.19 third person ratings g = 0.25 (both n.s.). All in all, mindfulness-based interventions in children and youths hold promise, particularly in relation to improving cognitive performance and resilience to stress. However, the diversity of study samples, variety in implementation and exercises, and wide range of instruments used require a careful and differentiated examination of data. There is great heterogeneity, many studies are underpowered, and measuring effects of Mindfulness in this setting is challenging. The field is nascent and recommendations will be provided as to how interventions and research of these interventions may proceed.

UNLABELLED: Fjorback LO, Arendt M, Ørnbøl E, Fink P, Walach H. Mindfulness-Based Stress Reduction and Mindfulness-Based Cognitive Therapy - a systematic review of randomized controlled trials. OBJECTIVE: To systematically review the evidence for MBSR and MBCT. METHOD: Systematic searches of Medline, PsycInfo and Embase were performed in October 2010. MBSR, MBCT and Mindfulness Meditation were key words. Only randomized controlled trials (RCT) using the standard MBSR/MBCT programme with a minimum of 33 participants were included. RESULTS: The search produced 72 articles, of which 21 were included. MBSR improved mental health in 11 studies compared to wait list control or treatment as usual (TAU) and was as efficacious as active control group in three studies. MBCT reduced the risk of depressive relapse in two studies compared to TAU and was equally efficacious to TAU or an active control group in two studies. Overall, studies showed medium effect sizes. Among other limitations are lack of active control group and long-term follow-up in several studies. CONCLUSION: Evidence supports that MBSR improves mental health and MBCT prevents depressive relapse. Future RCTs should apply optimal design including active treatment for comparison, properly trained instructors and at least one-year follow-up. Future research should primarily tackle the question of whether mindfulness itself is a decisive ingredient by controlling against other active control conditions or true treatments.

Although digital transformation offers a number of opportunities for today’s organizations, information systems scholars and practitioners struggle to grasp what digital transformation really is, particularly in terms of how it differs from the well-established concept of information technology (IT)-enabled organizational transformation. By integrating literature from organization science and information systems research with two longitudinal case studies—one on digital transformation, the other on IT-enabled organizational transformation—we develop an empirically grounded conceptualization that sets these two phenomena apart. We find that there are two distinctive differences: (1) digital transformation activities leverage digital technology in (re)defining an organization’s value proposition, while IT-enabled organizational transformation activities leverage digital technology in supporting the value proposition, and (2) digital transformation involves the emergence of a new organizational identity, whereas IT-enabled organizational transformation involves the enhancement of an existing organizational identity. We synthesize these arguments in a process model to distinguish the different types of transformations and propose directions for future research.

The recast of the European Union Renewable Energy Directive (RED II) entered into force in December 2018, followed by the Internal Electricity Market Directive (IEMD) and Regulation (IEMR) as part of the Clean Energy for all Europeans Package. The RED II, that the 28 Member States have until June 2021 to transpose into national law, defines “Renewable Energy Communities” (RECs), introduces a governance model for them and the possibility of energy sharing within the REC. It also provides an “enabling framework” to put RECs on equal footing with other market players and to promote and facilitate their development. This article defines "renewable energy clusters" that are comprised of complementarity of different energy sources, flexibility, interconnectivity of different actors and bi-directionality of energy flows. We argue that RECs and RE clusters are socio-technical mirrors of the same concept, necessary in a renewable energy transition. To test how these new rules will fare in practice, drawing on a secondary dataset of 67 best-practice cases of consumer (co-)ownership from 18 countries, each project is assessed using the criteria of cluster potential, and for the extent that they meet the RED II governance requirements of heterogeneity of members and of ownership structure. Nine cases were identified as having cluster potential all of which were in rural areas. Of these, five projects were found to be both RECs and RE clusters. The absence of the governance and heterogeneity criteria is observed in projects that fall short of the cluster elements of flexibility, bi-directionality and interconnectivity, while cluster elements occur where the governance and heterogeneity criteria are met. When transposing the new rules into national law we recommend careful attention to encourage complementarity of renewables, RECs in urban contexts and “regulatory sandboxes” for experimentation to find the range of optimal preferential conditions of the “enabling framework”.

Assessing factors that predict new product success ( NPS ) holds critical importance for companies, as research shows that despite considerable new product investment, success rates are generally below 25%. Over the decades, meta‐analytical attempts have been made to summarize empirical findings on NPS factors. However, market environment changes such as increased global competition, as well as methodological advancements in meta‐analytical research, present a timely opportunity to augment their results. Hence, a key objective of this research is to provide an updated and extended meta‐analytic investigation of the factors affecting NPS . Using Henard and Szymanski's meta‐analysis as the most comprehensive recent summary of empirical findings, this study updates their findings by analyzing articles published from 1999 through 2011, the period following the original meta‐analysis. Based on 233 empirical studies (from 204 manuscripts) on NPS , with a total 2618 effect sizes, this study also takes advantage of more recent methodological developments by re‐calculating effects of the meta‐analysis employing a random effects model. The study's scope broadens by including overlooked but important additional variables, notably “country culture,” and discusses substantive differences between the updated meta‐analysis and its predecessor. Results reveal generally weaker effect sizes than those reported by H enard and S zymanski in 2001, and provide evolutionary evidence of decreased effects of common success factors over time. Moreover, culture emerges as an important moderating factor, weakening effect sizes for individualistic countries and strengthening effects for risk‐averse countries, highlighting the importance of further investigating culture's role in product innovation studies, and of tracking changes of success factors of product innovations. Finally, a sharp increase since 1999 in studies investigating product and process characteristics identifies a significant shift in research interest in new product development success factors. The finding that the importance of success factors generally declines over time calls for new theoretical approaches to better capture the nature of new product development ( NPD ) success factors. One might speculate that the potential to create competitive advantages through an understanding of NPD success factors is reduced as knowledge of these factors becomes more widespread among managers. Results also imply that managers attempting to improve success rates of NPDs need to consider national culture as this factor exhibits a strong moderating effect: Working in varied cultural contexts will result in differing antecedents of successful new product ventures.

Large generative AI models (LGAIMs), such as ChatGPT, GPT-4 or Stable Diffusion, are rapidly transforming the way we communicate, illustrate, and create. However, AI regulation, in the EU and beyond, has primarily focused on conventional AI models, not LGAIMs. This paper will situate these new generative models in the current debate on trustworthy AI regulation, and ask how the law can be tailored to their capabilities. After laying technical foundations, the legal part of the paper proceeds in four steps, covering (1) direct regulation, (2) data protection, (3) content moderation, and (4) policy proposals. It suggests a novel terminology to capture the AI value chain in LGAIM settings by differentiating between LGAIM developers, deployers, professional and non-professional users, as well as recipients of LGAIM output. We tailor regulatory duties to these different actors along the value chain and suggest strategies to ensure that LGAIMs are trustworthy and deployed for the benefit of society at large. Rules in the AI Act and other direct regulation must match the specificities of pre-trained models. The paper argues for three layers of obligations concerning LGAIMs (minimum standards for all LGAIMs; high-risk obligations for high-risk use cases; collaborations along the AI value chain). In general, regulation should focus on concrete high-risk applications, and not the pre-trained model itself, and should include (i) obligations regarding transparency and (ii) risk management. Non-discrimination provisions (iii) may, however, apply to LGAIM developers. Lastly, (iv) the core of the DSA's content moderation rules should be expanded to cover LGAIMs. This includes notice and action mechanisms, and trusted flaggers.

Classical social and cultural theory disregards the spatial and affective dimensions of social phenomena because of its anti-technological and anti-aesthetic bias. The first part of my paper digs into the reasons for this ignorance. Against this background, the second part outlines an alternative conceptual proposal, which I label a praxeological perspective. This approach offers a framework for analysing emotions and affects that simultaneously pays attention to artefacts and to space. It integrates all of these as basic components of sociality and, by doing so, avoids both the pitfall of their complete culturalisation and that of their total naturalisation. The aim is to achieve a basic ‘aesthetisation’ and ‘materialisation’ of cultural theory, instead. The third part, finally, illuminates the interconnection between emotions and space and argues that in order to explain the cultural change of affective structures in history, the analysis of the emergence of new artefact-space complexes is indispensable.

FIFTY-FIVE YEARS AFTER THE FALL OF FASCISM AND THE END OF THE Second World War, right-wing radical movements and parties are part of the political normalcy in many Western democracies. In the face of the twentieth-century experiences of fascism and state socialism, and their failures, this stubborn persistence seems at the same time anachronistic and frightening. While there is no shortage of explanations and interpretations of this phenomenon in an evergrowing body of literature, most studies focus on national trends and derive their criteria from country-specific histories and discourses. Serious comparative scholarship on the radical right is still in its infancy. This article is a plea for more comparative research on rightwing radicalism at the turn of the century. It begins by highlighting the three central dimensions of the problem. First, one must state that contemporary right-wing radicalism is an international phenomenon. Thus, more than before, comparative studies are needed both to analyse the international quality and to specify the nation-specific characteristics of the radical right in each country. Secondly, it must be borne in mind that contemporary right-wing radicalism is a modern phenomenon. It has undergone a phase of renewal, as a result of social and cultural modernization shifts in post-war Europe. Thus it is only vaguely connected with previous versions. Terms like ‘fascism’ or ‘neo-fascism’ which suggest a historical continuity from Munich to Mölln and Magdeburg in Germany, or from Vichy to Vitrolles in France, become increasingly obsolete. The third factor to bear in mind is that contemporary right-wing radicalism is a complex phenomenon. The ongoing specialization and compartmentalization in the social sciences, such as discourse analysis, party and electoral research, and youth sociology – to name but a few of the approaches applied to the radical right – fail to do justice to the complexity of the subject. Clearly, the many faces of right-wing radicalism require clear analytical distinctions, but ultimately they need to be approached in a truly interdisciplinary way.

Based on a meta-analysis, this study aims to clarify the influence of online review valence (i.e., whether reviews in a review set are predominantly positive or negative) on various dependent variables, in particular on perceived usefulness of the reviews and on attitudes toward the product. The findings suggest that review valence affects perceived usefulness in a different way than it affects attitudes. We find an optimum impact level for perceived usefulness and a ceiling effect for attitudes. Primarily negative review sets that include few positive reviews show the strongest effect on perceived usefulness, while positive review sets that include few or no negative reviews are most successful in influencing attitudes. Additionally, review valence has a stronger influence on perceived usefulness when the reviews refer to experience (rather than search) products, and it has a stronger influence on attitudes for unfamiliar (rather than familiar) brands. Finally, the strongest influence of review valence refers to recommendation intentions. These findings provide several implications for researchers and practitioners.

This study uses meta-analytic techniques to examine the number of exposures that maximize consumer response to an ad. The results show that in an experimental setting maximum attitude is reached at approximately ten exposures, while recall increases linearly and does not level off before the eighth exposure. The findings are of interest for two opposing schools of thought in the advertising literature on effective frequency. They support the repetitionists’ beliefs over the minimalists’ beliefs on the number of ad exposures needed for maximum consumer response. The study further investigates whether the repetition effects depend on contingent factors. Low involvement and spaced exposures enhance repetition effects on attitude toward the brand. Embedded advertising and massed exposures enhance the repetition effects on recall. Repetition effects decay over time for both attitude toward the brand and recall. The study provides important implications for researchers by contributing to the discussion on effective frequency and providing support for the repetitionists’ view. This view has implications for practitioners who try to optimize advertising frequency.

The recast of the Renewable Energy Directive (RED II) provides an enabling framework for “Renewable Energy Communities” (RECs) that is being transposed into law by the 27 European Union Member States by June 2021. RECs are majority owned by local members or shareholders who are authorized to share energy within the community, offering the potential to unlock private investment and financing for renewable energy sources and provide social benefits. However, successful implementation and a just energy transition requires the coupling of technological solutions with more open decision making, based on sound analysis, knowledge of engineering, spatial planning, and social science. We argue that financing and ownership models that address renewable energy complementarity, spatial organization of resource potential, demographics, pushback from incumbents, and inclusion of traditionally marginalized groups, are common issues across all Member States that are crucial for the transposition of RED II and a just energy transition. This paper highlights the benefits and challenges of widespread development of RECs, and using examples from the pending transposition process provides policy advice for effective implementation of the RED II with respect to RECs.

International comparisons of new radical right‐wing parties usually focus on differences in electoral fortunes, party organisations and leadership. This article uses a different angle by focusing on public policy impact and the role these parties play in the parliamentary and executive arenas. The research is driven by the hypothesis that under the conditions of stable democracy, holding office produces a net result in a ‘taming effect’ on radical right‐wing actors rather than a sharp ‘right turn’. Evidence f rom four countries (Germany, France, Italy and Austria) shows that parliamentary presence alone does not result in policy effects. When the radical right holds executive office, a ‘right turn’ occurs primarily in cultural policies. Overall, real effects of radical right‐wing politics occur largely as a result of the interaction between the radical right and established actors ‐regardless of the radical right's assuming power.

This paper brings into focus the concept of organizational secrecy, defined as the ongoing formal and informal social processes of intentional concealment of information from actors by actors in organizations. It is argued that existing literature on the topic is fragmented and predominantly focused on informational rather than social aspects of secrecy. The paper distinguishes between formal and informal secrecy and theorizes the social processes of these in terms of identity and control. It is proposed that organizational secrecy be added to the analytical repertoire of organization studies.

Previous research on advertising effectiveness of celebrity endorsers has applied immediate measures only and neglected delayed effects, although the literature suggests that endorser traits, such as attractiveness or expertise, trigger either cognitive or affective processes that do not necessarily occur immediately and simultaneously. In order to fill this research gap, this study applies the affective-cognitive framework and investigates immediate versus delayed effects of celebrity endorsers’ attractiveness and expertise on attitude towards brands (as related to transformational products). The results show that attractiveness is the dominant driver in the immediate condition, whereas in the delayed condition a high expertise exerts its influence. High expertise is particularly effective when the celebrity endorser is highly attractive, whereas the impact of less attractive celebrity endorsers with low expertise can even worsen over time.

Abstract In recent times, Richard Florida's ‘creative class’ theory, which deals with a particular set of regional success factors (technology, talent and tolerance) has received quite a positive reception among regional scientists and politicians in North America and Europe. Particularly on the urban level, Florida's concept has become a ‘message of hope’ to guide poor and declining localities to a future path of successful development. Florida's approach can be criticized for its highly affirmative concept of class and the current mode of capitalist development. This article starts from a deconstruction of the notion of a creative class and deals with the aggregation and co‐location problems that plague Florida's concept. On the basis of empirical research on the regional distribution of diverse occupational groups in Germany, the article proves specifically that the ‘dealer class’— or in Florida's terms, creative professionals — does not have a significant or positive impact on the success of urban areas in developing sustainable economic structures. Résumé Ces dernières années, la théorie de la ‘classe créative’ de Richard Florida, qui porte sur un ensemble spécifique de facteurs de réussite régionale (technologie, talent et tolérance), a été accueillie très favorablement, en Amérique du Nord et en Europe, dans les milieux politiques et de la recherche sur les régions. Plus précisément, au niveau urbain, le concept de Florida s’est transformé en ‘message d’espoir’ guidant les localités pauvres ou en déclin sur la voie d’un développement réussi. L’approche de Florida est critiquable par son concept de classe fortement antidiscriminatoire et du fait des modalités d’évolution actuelles du capitalisme. L’article commence par une déconstruction de la notion de classe créative et aborde les problèmes d’agrégation et de co‐localisation qui empoisonnent le concept de Florida. À partir d’une étude empirique sur la répartition régionale de divers groupes professionnels en Allemagne, il est démontré spécifiquement que la ‘dealer class ou classe des courtiers’ (les creative professionals au sens de Florida) n’a pas d’impact significatif ou positif sur la réussite des zones urbaines via le développement de structures économiques durables.

This article addresses the relationship between religion and politics in liberal democracies from a public policy angle. The analysis shows that contrary to the general secularization thesis, there is a visible religious impact on public policy, but it varies according to what measure of secularization is used. Confessional heritage (Catholicism versus Protestantism) and cultural values (levels of religiosity) are better predictors than institutional differentiation or political mobilization. When confessional heritage is held constant, the institutional impact increases. It is not surprising that Catholic countries produce less than fully liberal abortion policies, but the most restrictive abortion policies are found in those Catholic countries where high levels of religiosity persist. Moreover, a strong presence of religious parties is not associated with restrictive abortion policies, but in all countries with moderate to high levels of religiosity and with strong Christian Democratic parties and only there, moderate or “distress” models of abortion exist.

This study explores how researchers' analytical choices affect the reliability of scientific findings. Most discussions of reliability problems in science focus on systematic biases. We broaden the lens to emphasize the idiosyncrasy of conscious and unconscious decisions that researchers make during data analysis. We coordinated 161 researchers in 73 research teams and observed their research decisions as they used the same data to independently test the same prominent social science hypothesis: that greater immigration reduces support for social policies among the public. In this typical case of social science research, research teams reported both widely diverging numerical findings and substantive conclusions despite identical start conditions. Researchers' expertise, prior beliefs, and expectations barely predict the wide variation in research outcomes. More than 95% of the total variance in numerical results remains unexplained even after qualitative coding of all identifiable decisions in each team's workflow. This reveals a universe of uncertainty that remains hidden when considering a single study in isolation. The idiosyncratic nature of how researchers' results and conclusions varied is a previously underappreciated explanation for why many scientific hypotheses remain contested. These results call for greater epistemic humility and clarity in reporting scientific findings.

Since the introduction of the persuasion knowledge model more than 25 years ago, many research studies have investigated how consumers’ persuasion knowledge affects their reactions to persuasion attempts. While most results have shown that persuasion knowledge increases coping responses and leads to less favorable evaluations of marketer actions, the findings vary considerably, leaving researchers with a limited understanding of the substance and structure of persuasion knowledge effects and the conditions that explain their variability. To develop a better understanding of persuasion knowledge effects in the marketplace, this study builds on the concept of persuasion to predict responses to marketers’ attempts to persuade consumers with different levels of persuasion knowledge. The study presents a meta‐analysis of the findings in 148 papers and 171 distinct data sets. Persuasion knowledge effects can be viewed as substantial compared with persuasion attempts, but persuasion knowledge cannot suppress or eliminate persuasion effects in the marketplace, as it only reaches around 50% of the explanatory power of persuasion. Persuasion knowledge effects on evaluations and coping depend on the characteristics of the persuasion process. All persuasion elements that help consumers identify and better understand benefits not just for themselves, but also for marketers and how marketers realize their benefits—such as the use of personal communication, communication about unfamiliar products or products with experience attributes, and receiver experience—lead to less favorable effects for marketers. This paper’s insights provide a new framework for persuasion knowledge effects in the marketplace, ideas for future research, and implications for researchers, consumers, policymakers, and marketers.

The advertising literature includes extensive research on the occurrence and effects of gender-role portrayals in advertising. None of these studies has examined the ways in which humor affects depictions and the advertising effectiveness of these portrayals. This article reports the results of content-analytic and experimental studies that investigate the occurrence and effectiveness of gender stereotyping in humorous and nonhumorous advertising. The findings from these studies are in line with the assumptions of information processing theories. They indicate that the way women and men are stereotyped in advertising is dependent on humor; in particular, traditional male stereotypes are more prevalent in humorous ads, whereas traditional female stereotypes are more prevalent in nonhumorous ads. With respect to the influence of these stereotypes, humor improves consumers’ attitudes, particularly if nontraditional stereotyping is utilized instead of traditional stereotyping. Furthermore, humor in stereotyped advertising influences women more than men. Women evaluate gender portrayals more favorably and as more credible in humorous ads than in nonhumorous ads, particularly when nontraditional stereotyping instead of traditional stereotypes are used. These findings provide implications for gender-role and humor research in advertising and for practitioners who wish to increase the effectiveness of ads that use stereotypes.
