Deploying a time-lagged questionnaire method implemented over four business quarters, data is generated from 1600 paired samples (managers and employees) in R&D units of Taiwanese technology firms. The structural equation modeling results reveal that (1) participative leadership is positively related to employee exploratory innovation; (2) coworker knowledge and (3) absorptive capacity partially mediate the relationship between participative leadership and employee exploratory innovation independently; and, (4) coworker knowledge sharing in combination with absorptive capacity partially mediates this relationship. The results extend previous research on participative leadership and innovation by demonstrating that participative leadership is related to employee exploratory innovation (Lee and Meyer-Doyle, 2017; Mom et al., 2009).Results also confirm that participative leadership drives employee exploratory innovation through employee absorptive capacity. This reinforces the need highlighted by Lane et al. (2006) to investigate the role of absorptive capacity at the individual-level. Collectively, while participative leadership is important for employee exploratory innovation it is the knowledge mechanisms existing and interacting at the employee-level that are central to generating increased employee exploratory innovation from this leadership approach

Construction of a Fish-like Robot Based on High Performance Graphene/PVDF Bimorph Actuation Materials.

Smart actuators have many potential applications in various areas, so the development of novel actuation materials, with facile fabricating methods and excellent performances, are still urgent needs. In this work, a novel electromechanical bimorph actuator constituted by a graphene layer and a PVDF layer, is fabricated through a simple yet versatile solution approach. The bimorph actuator can deflect toward the graphene side under electrical stimulus, due to the differences in coefficient of thermal expansion between the two layers and the converse piezoelectric effect and electrostrictive property of the PVDF layer. Under low voltage stimulus, the actuator (length: 20 mm, width: 3 mm) can generate large actuation motion with a maximum deflection of about 14.0 mm within 0.262 s and produce high actuation stress (more than 312.7 MPa/g). The bimorph actuator also can display reversible swing behavior with long cycle life under high frequencies. on this basis, a fish-like robot that can swim at the speed of 5.02 mm/s is designed and demonstrated. The designed graphene-PVDF bimorph actuator exhibits the overall novel performance compared with many other electromechanical avtuators, and may contribute to the practical actuation applications of graphene-based materials at a macro scale

Drivers of innovation ambidexterity in small-to-medium-sized firms

Balancing explorative and exploitative innovation ambidextrously has emerged as one of the foremost questions in management research. While a firm's ability to jointly pursue both exploitative and explorative innovation has been conceived as having positive performance effects, scholarly efforts to resolve the ambidexterity question have left a disproportionate gap in our understanding of how innovation ambidexterity can be achieved, particularly so in small-to-medium-sized firms (SMEs). The state of the debate is such that SMEs must largely rely on prescriptions tested with large firms to inform their ambidexterity initiatives. This study focuses on the characteristics of top managers and features of organizational structure and context in facilitating the appearance of ambidexterity in SMEs, and the mediation effect of innovation ambidexterity between structural, contextual, and leadership characteristics on SME performance. Results indicated that SMEs could achieve a close balance of explorative and exploitative innovations (BD) through shaping right international organizational structures and adopting appropriate leadership styles. Further, BD mediates the relationship between the structural, contextual, and leadership characteristics on SME performance. SMEs could benefit from BD with relatively resources available

Understanding the Impact of Service Reputation on the Online Group-buying Behaviors

It has been well recognized that vendors’ reputation plays an important role in e-commerce. As a popular platform for promoting the services or products online, groupon websites have developed various reputation systems to assist the customers in making their purchase decisions. This paper performs an empirical study to investigate the impact of service reputation on the groupon buying behaviors using data from a major groupon website in China. A set of service reputation metrics is developed to measure the service reputation for different service providers, and the groupon buying behavior is measured by the amount of users participating in the corresponding collective buying activity. Correlation analysis is carried out to find out the relationship between the service reputation and the groupon purchase behaviors. Our research indicates the necessity for an improvement for the current service reputation systems of the groupon web sites

What’s Cooking? – Cognitive Training of Executive Function in the Elderly

Executive function involves the efficient and adaptive engagement of the control processes of updating, shifting, and inhibition (Miyake, 2000) to guide behavior toward a goal. It is associated with decrements in many other cognitive functions due to aging (West, 1996; Raz, 2000) with itself particularly vulnerable to the effect of aging (Treitz et al., 2007). Cognitive training in the form of structural experience with executive coordination demands exhibited effective enhancement in the elderly (Hertzog et al., 2008). The current study was thus aimed at the development and evaluation of a training regime for executive function in the elderly. The breakfast cooking task of Craik and Bialystok (2006) was adapted into a multitasking training task in a session (pre-test vs. post-test) by group (control vs. training). In the training condition, participants constantly switched, updated, and planned in order to control the cooking of several foods and concurrently performed a table setting secondary task. Training gains were exhibited on task related measures. Transfer effect was selectively observed on the letter–number sequencing and digit symbol coding test. The cooking training produced short term increase in the efficiency of executive control processing. These effects were interpreted in terms of the process overlap between the training and the transfer tasks

AtPAN: an integrated system for reconstructing transcriptional regulatory networks in Arabidopsis thaliana

<p>Abstract</p> <p>Background</p> <p>Construction of transcriptional regulatory networks (TRNs) is of priority concern in systems biology. Numerous high-throughput approaches, including microarray and next-generation sequencing, are extensively adopted to examine transcriptional expression patterns on the whole-genome scale; those data are helpful in reconstructing TRNs. Identifying transcription factor binding sites (TFBSs) in a gene promoter is the initial step in elucidating the transcriptional regulation mechanism. Since transcription factors usually co-regulate a common group of genes by forming regulatory modules with similar TFBSs. Therefore, the combinatorial interactions of transcription factors must be modeled to reconstruct the gene regulatory networks.</p> <p>Description For systems biology applications, this work develops a novel database called <it>Arabidopsis thaliana </it>Promoter Analysis Net (AtPAN), capable of detecting TFBSs and their corresponding transcription factors (TFs) in a promoter or a set of promoters in <it>Arabidopsis</it>. For further analysis, according to the microarray expression data and literature, the co-expressed TFs and their target genes can be retrieved from AtPAN. Additionally, proteins interacting with the co-expressed TFs are also incorporated to reconstruct co-expressed TRNs. Moreover, combinatorial TFs can be detected by the frequency of TFBSs co-occurrence in a group of gene promoters. In addition, TFBSs in the conserved regions between the two input sequences or homologous genes in <it>Arabidopsis </it>and rice are also provided in AtPAN. The output results also suggest conducting wet experiments in the future.</p> <p>Conclusions</p> <p>The AtPAN, which has a user-friendly input/output interface and provide graphical view of the TRNs.

Internal and external antecedents of SMEs' innovation ambidexterity outcomes

PURPOSE. Prior studies have suggested that organizational and environmental antecedents are influential to the development of a balance dimension of innovation ambidexterity, which are proposed to be central to superior firm performance. However, little is known about how such antecedents affect the shaping of innovation ambidexterity in small to medium‐sized enterprises (SMEs) and how these innovations go on to shape firm performance. This paper aims to examine internal and external antecedents of SMEs' innovation ambidexterity outcomes. DESIGN/METHODOLOGY/APPROACH. The research used a survey method to investigate the 1,000 small‐and medium sized enterprises in Scotland. Firms were randomly selected from the FAME database. Of this sample, 265 firms (26.5 percent) responded to the survey. FINDINGS. The data analysis reveals that internal organizational structures in a highly dynamic environment stimulate the appearance of innovation ambidexterity. Moreover, it is found that the relationship between organizational and environmental forces and firm performance is partially mediated by a balance dimension of innovation ambidexterity. PRACTICAL IMPLICATIONS. The results show how dangerous the lack of adequate research of these issues at the SME level is. By contrast to larger firms, the results show how internal organizational structures and external environmental conditions affect SMEs to pursue a balance dimension of innovation ambidexterity. ORIGINALITY/VALUE. Prior studies have paid little attention to the effects of internal organizational structures and external environmental conditions on the appearance of a balance dimension of innovation ambidexterity within SMEs. This paper fills some of the gaps
