We found four types of championing responses in the 61 instances where initial idea advancement efforts did not bear fruit: lateral shifts, reworking, temporal shifts and moaning. In each of these, the idea was seen as valuable by the developer, but the attribution of initial failure and perceptions of effort-to-performance and performance-to-outcome expectancies varied in distinct combinations of conforming and nonconforming types of championing with varying intensity.

We collected data from 192 respondents in 45 teams from various multinational organizations and analysed it using a multilevel path analytic method, specifically Hierarchical Linear Modelling. The study's findings indicate that team-level perceived high-quality HR training positively predicts individual-level employee-rated managers' innovative work behaviour and employee-rated managers' innovative work behaviour is positively related to employees' thriving at work. This finding supports our hypothesis of an indirect positive effect from HR training quality to thriving via managers' innovative work behaviour. Furthermore, the cross-level analysis revealed that aggregated HR training quality strengthens the relationship signal that favours the manager's innovative work behaviour, which, in turn, positively affects their own thriving at work. Our research offers novel insights into the thriving process, underscoring the importance of considering both contextual and individual factors.

This research aims to examine if an organization's green HRM (GHRM) practices can foster green creativity among manufacturing sector employees through the serial mediation path of environmental concerns and employee engagement with environmental initiatives, using self-determination theory (SDT). To conduct this research, we collected and analysed data from 309 employees of manufacturing firms in Pakistan using partial least square structural equation modelling (PLS-SEM). The results supported a positive relationship between GHRM and green creativity and the role of environmental concern and employee engagement with environmental initiatives in mediating that relationship. Likewise, the findings indicated that the relationship between GHRM and green creativity would strengthen as employees become more environmentally concerned. Overall, this study contributes to the literature on HRM and environmental management by providing new insights into the critical role of GHRM in fostering green creativity.

As idea convergence processes usually focus on filtering out single ideas, the potential of solution-related knowledge among the heterogeneous ideas is not exploited in a sustainable manner. Transformer-based language models can process large sets of idea descriptions into digestible structures, with unprecedented capabilities for understanding and manipulating text. This study explores how they can help organizations and decision-makers navigate crowdsourced solution spaces efficiently and comprehensively. Inspired by theoretical concepts around problem-solving and innovation search, we conceptualize three related search practices—direct search, cluster exploration and pattern discovery—and illustrate them on 289 crowdsourced ideas for future mobility and energy services. Direct search can assist in identifying solutions that match pressing needs or subproblems. Cluster exploration enables aggregating semantically similar ideas into clusters to identify relevant needs. Pattern discovery synthesizes themes and interrelations to build a holistic understanding of potential solutions. The study contributes to the application of AI-assisted idea convergence by adding a new perspective beyond filtering out a few promising ideas.</p>","PeriodicalId":47923,"journal":{"name":"Creativity and Innovation Management","volume":null,"pages":null},"PeriodicalIF":3.7,"publicationDate":"2024-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/caim.12612","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140938388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previously, organizations worldwide focussed on creating workplaces that foster interaction and collaboration to enhance knowledge exchange and communication. Both are among the main drivers for stimulating creativity at the workplace, leading to increased innovation activities. Since offices are dramatically changing from lean, work-focused, and hierarchical workstations into employee-oriented, creativity-enhancing spaces with playground artefacts, the need for quantitative research on the effects of workplace design on creativity seems evident for researchers and practitioners. Although prior research has attempted to describe the physical work environment and its impact on creativity, empirical evidence is still lacking on what concrete attributes of a workplace employees perceive as inspiring. We therefore contribute to the existent body of knowledge by establishing a definition for inspiring physical workplaces as perceived by employees in times of digitalization and provide a conceptual model analysing the effects between workplace design, internal knowledge exchange, and creative problem-solving capacity. We assess our survey data with partial least squares structural equation modelling and provide first empirical evidence that our proposed formative index supports the common research agenda within the context of workplace design, and further, that aspects of workplace design not only enhance creative problem-solving capacity as an important dimension of creativity itself, but that this relationship is also partially mediated by internal knowledge exchange.</p>","PeriodicalId":47923,"journal":{"name":"Creativity and Innovation Management","volume":null,"pages":null},"PeriodicalIF":3.7,"publicationDate":"2024-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/caim.12611","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140832520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the relevance of innovation for economic progress and structural and cultural differences among regions, there is surprisingly little knowledge available on whether the knowledge developed from Western firms can be transferred to emerging economies. This dearth of knowledge is especially notable for the early phases of innovation processes. Rapid iterations between knowledge creation and learning are critical at the front end of innovation (FEI), a phase that, in turn, is crucial for innovation success. In a recently published article, Peña Häufler and co-authors developed the concept of rapid validity testing (RVT) and found support for its positive relation with innovation performance. Since the authors draw on a sample of Western firms, we explore whether the concept of RVT and its performance relevance remain valid across regional contexts. The data for this study stem from a sample of 1625 respondents from 232 firms in Europe and Latin America.
