Knowledge sharing is a fundamental source of competitive advantage. Social networks are thought to play an important role in knowledge sharing, but are presumed to create a trade-off such that a network can be optimized to promote either knowledge seeking or knowledge transfer, but not both. The trade-off, however, is premised on, and representative of a broader tendency to treat, brokerage and closure as contradictory network forms. We challenge this assertion and propose a theory of knowledge sharing with brokerage and closure as compatible and complementary. Evidence from a contract research and development firm broadly supports our theory. We also report the results of a simulation analysis, which illustrate that only in the extremely rare case when a network is characterized by nearly complete balance do brokerage and closure begin to create a trade-off.

As a new communication paradigm, social networking sites (SNS) have boosted information diffusion and viral marketing. Prior researchers have identified various factors affecting information dissemination on SNS. However, they often focus on limited factors and there is a lack of an integrated theoretical framework that explains aspects of relevant factors. Besides, the research on the impacts of relationships on individual retweeting behavior is still controversial. The purpose of this paper is to propose a theoretical framework to systematically investigate the determinants of individual dissemination behavior on SNS based on the elaboration likelihood model (ELM). Moreover, the authors also examine the relative importance of those relevant factors.

The authors randomly selected 1,250 members of Twitter and crawled posts published by each member since he/she created the Twitter account using Twitter API. The authors processed the data to create panel data and tested hypotheses with the panel logit model.

Factors both on the central route and on the peripheral route of ELM have positive impacts on individual dissemination behavior. Among them, information receiver-related factor and relationships-related factors are the most influential. Contrastingly, source-related factors are the least influential. Furthermore, the authors find that social tie strength mediates almost 50 percent of the effect of value homophily on individual dissemination behavior.

The authors are the first to directly apply ELM to examine individual dissemination behavior on SNS. By integrating factors into the two information processing routes, They incorporate relevant factors into the model and systematically analyze their impacts on individual retweeting behavior on SNS. The research offers at least one explanation for the contradictory findings about the effect of homophily on individual sharing behavior in previous research. The authors propose new variables that gauge topical relevance and interpersonal value homophily on SNS.

Teleoperated minimally invasive surgical robots can significantly enhance a surgeon's accuracy, dexterity and visualization. However, current commercially available systems do not include significant haptic (force and tactile) feedback to the operator. This paper describes experiments to characterize this problem, as well as several methods to provide haptic feedback in order to improve surgeon's performance. There exist a variety of sensing and control methods that enable haptic feedback, although a number of practical considerations, e.g. cost, complexity and biocompatibility, present significant challenges. The ability of teleoperated robot‐assisted surgical systems to measure and display haptic information leads to a number of additional exciting clinical and scientific opportunities, such as active operator assistance through “virtual fixtures” and the automatic acquisition of tissue properties.

This study aims to investigate the relationships between radical innovation, market forces and political/business relationships in China by combining social capital theory and contingent theory. The paper focuses on how two types of managerial ties (i.e. business and political ties) impact firms’ capacity for radical innovation. It also examines the different moderating effects of market forces (i.e. demand uncertainty, technological turbulence and competitive intensity) on the linkage of managerial ties with radical innovation in the Chinese transitional context.

A systematic literature review on managerial ties, radical innovation and market forces in emerging markets provides the theoretical foundation of our conceptual model and hypothesis. Using a survey sample of 119 Chinese firms, the authors conduct a regression analysis on the theoretical model and hypotheses.

The results show that business ties have an inverted U-shape effect on radical innovation, while political ties have a positive impact on radical innovation. Furthermore, the market forces in transitional economies (i.e. demand uncertainty, technological turbulence and competitive intensity) have different moderating effects on the relationships between two types of managerial ties and Chinese firms’ radical innovation.

This study adopts its data set from the Chinese context. It would be necessary to replicate this research in other transitional economies because of specific differences between China and other transitional economies.

Findings from our study indicate that firms which wish to succeed in radical innovation may need to adapt their tie-based strategies according to different market settings.

The paper is original in its comparative investigation of the effect of business ties and political ties on radical innovation in contingent transitional market environments using a combination of social capital and contingent theories.

This study applies Oviatt and McDougall’s (2005) model of forces influencing the speed of internationalisation to small, export oriented enterprises. The purpose of this paper is to explore the significance of the forces enabling, motivating, mediating and moderating internationalisation in small and medium-sized enterprises (SMEs), and the manner in which these forces manifest themselves in the market.

A qualitative research approach utilising eight case studies within Norway and Ireland was adopted in order to facilitate theory building required for this study.

The findings demonstrate that four forces in particular are found to be strongly significant to the speed of internationalisation among the case SMEs: the enabling force of technology, the mediating force of entrepreneurial actor perceptions/owner-managers’ global vision and the moderating forces of foreign market knowledge and tie strength in networks.

The empirical evidence has several implications for managers and policy regarding influencing the speed of internationalisation process. The enabling force (technology) has implications for government in their support of the SME macro environment. The motivating force (competition) has implications for government, in understanding what motivates entrepreneurs to enter international markets. The two moderating forces (foreign market knowledge and network tie strength) have implications for managers and can be leveraged through product innovation, increased focus on intellectual property rights for better protection against copycats, and through active and deliberate international networking.

The paper suggests adjustments to Oviatt and McDougall’s (2005) model, permitting researchers to gain an in-depth understanding of the complex reality of SME internationalisation.

Prior research has examined the sociopolitical force as simply a part of all types of environmental pressures, yet we argue that this force calls for a unique examination of marketing's role in firm responses to sociopolitical pressures. Understanding the degree to which firms attempt to manage forces and pressures in the external business environment is key to understanding marketing's role in impeding vs aiding public policy initiatives, and is the problem this research investigates.

Using structural equation modeling, data from 71 firms demonstrate that managing the sociopolitical force is, in fact, distinct from managing the other four market-based forces – consumer demand, supplier power, competition and technological shifts. Managing the sociopolitical force is shown to require fundamentally different skills and resources.

Results suggest that firm sociopolitical receptivity drives attempts to influence this unique external business environmental force, in turn limiting marketplace sociopolitical receptivity. Furthermore, attempts to influence such a unique force relies on resource-light marketing resources, which limits resource-heavy marketing.

Managing a political force with marketplace ramifications involves strategy that utilizes marketing, but is driven by relationships with social and political agents. This is truly an environmental management concept distinct from the management of the other four market-based forces. The analysis in this study demonstrates that managing another environmental force (i.e. competition force) involves different receptivity influences and marketing tactic outcomes.

This study attempts to explore how a cultural and creative firm's competitive advantages can be maintained through the accumulation of intellectual capital and entrepreneurial orientation. Another goal of this study is to identify the different mechanisms of network ties to explore the interrelationships between organizational capital and competitive advantage in the context of Taiwan and China.

Study 1 and study 2 settings are applied, and 786 samples (i.e., 418 samples from Taiwan and 368 samples from China) are used to examine the proposed model.

Study 1 reveals that entrepreneurial orientation may influence the organization capital through human capital and social capital, which discloses the mutual relationships of intellectual capital. Further, the results of study 2 confirm the mediating role of intellectual capital that links the relationships between entrepreneurial orientation and competitive advantage. Specifically, this study also discovered that firms with more network or political ties (e.g. the Chinese samples) and business ties (e.g. the Taiwanese samples) tend to amplify the effects of organizational capital on competitive advantage.

According to our empirical results, cultural and creative managers should build a learning mechanism to encourage and develop entrepreneurial orientation and intellectual capital capacities and to provide means of understanding of customers' changing expectations. Hence, in enhancing entrepreneurial orientation and intellectual capital cultural and creative firms can develop a competitive advantage over competitors. Our findings also offer new insight to support further studies of the benefits of managerial ties for firms operating in Guanxi cultural settings in Chinese contexts.

Most previous studies on tourism strategies have disregarded the impacts and different roles of government (e.g. political ties) and business (e.g. business ties) forces on cultural and creative firms' competitive advantages, suggesting a need to address social network issues in response to dynamic tourism environments. Therefore, this study examines differences in network ties and the differences observed between China and Taiwan in the context of Chinese cultural and creative firms.

The calculation of the shear capacity of inclined section for prestressed reinforced concrete beams is an important topic in the design of concrete members. The purpose of this paper, based on the truss-arch model, is to analyze the shear mechanism in prestressed reinforced concrete beams and establish the calculation formula for shear capacity.

Considering the effect of the prestressed reinforcement axial force on the angle of the diagonal struts and regression coefficient of softening cocalculation of shear capacity is established. According to the shape of the cracks of prestressed reinforced concrete beams under shear compression failure, the tie-arch model for the calculation of shear capacity is established. Shear-failure-test beam results are collected to verify the established formula for shear bearing capacity.

Through theoretical analysis and experimental beam verification, it is confirmed in this study that the truss-arch model can be used to analyze the shear mechanism of prestressed reinforced concrete members accurately. The calculation formula for the angle of the diagonal struts chosen by considering the effect of prestress is accurate. The relationship between the softening coefficient of concrete and strength of concrete that is established is correct. Considering the effect of the destruction of beam shear plasticity of the concrete on the surface crack shape, the tie-arch model, which is established where the arch axis is parabolic, is applicable.

The formula for shear capacity of prestressed reinforced concrete beams based on this theoretical model can guarantee the effectiveness of the calculation results when the structural properties vary significantly. Engineers can calculate the parameters of prestressed reinforced concrete beams by using the shear capacity calculation formula proposed in this paper.

The purpose of this paper is to recover the deficiency of existing tie force (TF) methods by considering the decrease in section strength due to cracking and by selecting limit state of collapse according to section properties.

A substructure is selected by isolating the connected beams from the entire structure. For interior joints, the TFs in the orthogonal beams are obtained by catenary action. For corner joints, the TFs are assessed by beam action. For edge joints, however, the resistance is gained by greater of the resistance under catenary action for periphery beams and beam action for all the connecting beams in both directions. For catenary action, the TF capacities must satisfy Equation (20). On the other hand, for beam action, the TF must satisfy Equation (16), while R is calculated from Equation (17). In the case where the length of the connecting beams is similar, Equation (19) can be used.

Closed form solutions are available for TFs on both beam and catenary stages.

The proposed formulation makes designing more practical and convenient. However, the proposed formulation had good agreement with experimental results.
