Abstract

Purpose

The purpose of this paper is to realize the integrated optimization of process planning and scheduling in printed circuit board assembly (PCBA).

Design/methodology/approach

Logical and numerical contour matrix is used to describe the constituent of component and machine for different PCBA processes on the basis of polychromatic sets (PS) theory, and a PS model of PCBA is built. A hybrid genetic algorithm (GA) is developed to optimize the component allocation, PCB assignment and assembly sequence simultaneously.

Findings

Integration of PCBA process planning and scheduling (PCBAPPS) can bridge the gap between design and manufacturing to guarantee the assembly quality and improve the production efficiency. However, PCBAPPS have to search for the optimal result in their own vast solution space. They are complex combinatorial optimization problems. The optimization of PCBAPPS constructs a unified solution space which includes two sub‐solution space stated above. In this paper, dynamic optimization of PCBAPPS is implemented and the solution efficiency is improved.

Originality/value

PS model holds unified standard form on the basis of logical contour and numerical matrix. It is adopted to describe the static structure and dynamic characteristic of PCBA system and combine with GA to solve the integrated optimization problem of PCBAPPS effectively and dynamically.

Abstract

Although an important facet of modernist architecture in which function plays a prominent role, building flexibility is not entirely a new concept. Its relevance transcends generations, allowing space and structure to evolve through time. This paper investigates the relationship among main building structures, infill elements, and space by studying examples in ancient Chinese architecture. It reveals the role of building owners, users, and craftsmen from a survey of historical documentation. In studying these examples, it is concluded that craftsmen in ancient China were involved not only during the construction phase but throughout the period of use as well. Thus, in select cases, the relationship between craftsmen and owners or users had been preserved for generations. Finally, this paper suggests potential strategies for the building industry and technology in the move towards sustainable development.

This paper aims to examine alliance governance at different hierarchical levels.

Abstract

Purpose

This paper aims to examine alliance governance at different hierarchical levels.

Design/methodology/approach

The data is collected from both top-level and operating-level managers in 286 strategic alliances in China (a total of 572 managers). Hierarchical moderated regression models are adopted to test the hypotheses and two-stage regression analyzes are used to correct for endogeneity.

Findings

This paper finds that relational governance has a greater impact on alliance performance than contract utilization at the top level. Furthermore, the simultaneous use of relational governance at the top and operating levels have a detrimental impact on alliance performance. Finally, top-level contract utilization has a negative interaction with operating-level relational governance but a positive interaction with operating-level contract utilization.

Research limitations/implication

First, the cross-sectional nature of the data collection approach provides only a snapshot of how each type of governance mechanism and its interactions affect alliance performance. Second, the sample is limited to firms located in emerging markets.

Practical implications

Managers should realize that the effectiveness of contract and relational governance mechanisms varies across different management levels and they should be cautious about the cross-level governance mechanism alignment.

Originality/value

This study advances the interfirm governance literature in that this paper examined alliance governance at different hierarchical levels and provides new insights into the ongoing debate on whether the contract and relational governance mechanisms function as complements or substitutes by exploring the governance alignment across different alliance hierarchies.

Abstract

Purpose

The purpose of this study is investigating the effect of using multi-phase nanofluids, Rayleigh number and baffle arrangement simultaneously on the heat transfer rate and Predict the optimal arrangement type of baffles in the differentiation of Rayleigh number in a 3D enclosure.

Design/methodology/approach

Simulations were performed on the base of the L25 Taguchi orthogonal array, and each test was conducted under different height and baffle arrangement. The multi-phase thermal lattice Boltzmann based on the D3Q19 method was used for modeling fluid flow and temperature fields.

Findings

Streamlines, isotherms, nanofluid volume fraction distribution and Nusselt number along the wall surface for 104 < Ra < 108 have been demonstrated. Signal-to-noise ratios have been analyzed to predict optimal conditions of maximize and minimize the heat transfer rate. The results show that by choosing the appropriate height and arrangement of the baffles, the average Nusselt number can be changed by more than 57 per cent.

Originality/value

The value of this paper is surveying three-dimensional and two-phase simulation for nanofluid. Also using the Taguchi method for Predicting the optimal arrangement type of baffles in a multi-part enclosure. Finally statistical analysis of the results by using of two maximum and minimum target Function heat transfer rates.

Abstract

Purpose

The objective of this study is to investigate the relationship between psychological empowerment and employee creativity with the mediating role of creative process engagement and intrinsic motivation by testing the research model.

Design/methodology/approach

Data were collected from in-depth interviews and surveys of 420 Vietnamese telecommunications enterprises employees. To test models and hypotheses, the collected data has been processed through Cronbach's alpha analysis, exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and structural equation modeling (SEM) using SPSS 22.0 and AMOS 24.0 tools.

Findings

The results confirm that psychological empowerment has a positive direct and indirect relationship through creative process engagement and intrinsic motivation with employee creativity.

Research limitations/implications

The main limitation of this paper is that a full study of the impact of leadership style on psychological empowerment and psychological empowerment to employee creativity should be conducted in the future at Vietnamese telecommunications enterprises.

Practical implications

Telecommunications enterprises managers who want to stimulate employee creativity need to pay attention to empowering workers and creating conditions for them to participate in the creative process when doing work.

Originality/value

The main contribution of this research is to apply theories of psychological empowerment, self-determination and composition theory of creativity to understand the relationship between psychological empowerment, creative process engagement, intrinsic motivation and employee creativity of telecommunications enterprises employees in the context of a developing country in Asia.

This paper aims to understand the role that money plays in polygamous marriages among the Hui ethnic group in Northwest China.

Abstract

Purpose

This paper aims to understand the role that money plays in polygamous marriages among the Hui ethnic group in Northwest China.

Design/methodology/approach

This study conducted in-depth interviews, focus group discussions and observations based on snowball sampling of individuals who voluntarily agreed to participate from June to December 2010, and during the summer of 2011, in Qinghai in Northwest China. Follow-up interviews and observations were conducted in 2015.

Findings

This study examines how love and money intersect and work together to sustain the participants’ polygamous marriages. The study concludes that material desires unite love with money to make love consumable. With the help of money, love between the sexes is transformed into desirable consumption through economic activities associated with leisure, gift giving and religious beliefs to articulate individualism

Originality/value

This study is the first to explore money’s role in the experience of polygamy among the Hui ethnic group in China.

Abstract

Purpose

This chapter has three central goals: First, it aims to introduce the concept of consumers’ online brand endorsements, which we define as consumers’ intentional, public, and positive online affiliations with brands (e.g., liking a brand page on Facebook). Second, it provides an overview of the drivers and consequences of this phenomenon. Third, it answers the question whether and when the broadly adopted marketing strategy of consumers’ online brand endorsements is feasible.

Approach

To accomplish these goals, we conducted a general review of the literature.

Findings

We identified three different drivers of consumers’ online brand endorsements: Identity-related drivers, brand-related drivers, and community-related drivers. Based on the literature we suggest that from the perspective of the endorsing consumer, online brand endorsements have the potential to be a two-sided sword.

The greater potential of this marketing technique appears to rely on the fact that consumers’ online brand endorsements are broadcasted to a gigantic network of other consumers and their potential to be contagious.

Originality/value

Consumers’ online brand endorsements are a new phenomenon and therefore quite understudied. Still, many brands have social media marketing strategies that aim to acquire huge amounts of endorsements by their consumers. This chapter contributes to our knowledge about the underlying mechanisms of consumers’ online brand endorsements. Moreover, it shows how and when consumers’ online brand endorsements can be a feasible marketing strategy.

Abstract

The digital and material traceability of our interactions in organizations are nowadays the subject of very advanced analyses through tools known as social media analytics (SMA). As thinking (infrastructure), SMA tools constitute objects to think of our digitally mediated interactions with. It produces a substratum (a new meaning) that would not exist otherwise, and enacts different types of reasoning that hypothetically influence community managers’ or members’ sensemaking of digitally mediated interactions. This chapter proposes to look behind the curtain of charts and graphs, in order to highlight the performativity of the interactions between the different machines and the traces of our digitally mediated interactions. Drawing on a detailed analysis of the fabric of SMA, this chapter highlights the explanatory power of a communication perspective on types of reasoning enacted by thinking infrastructures. First, considering the SMA tool as an editorial enunciation allows us to see it as a process implying several beings (e.g. machines, humans and logs) that are not without consequences. Second, we show that these beings have different modalities of interactions with each other, and that these modalities of interactions influence the materiality of the digital traces of past interactions. Third, throughout the process, we demonstrate the fragility and variability of their materiality. Finally, faced with the rise of a technological deterministic discourse, which tends to portray the exploitation of our digital traces as an objective way of representing the collaborative practices that make up the organization, our research aims, on the contrary, to demonstrate their relativity.

Abstract

Purpose

The purpose of this paper is to provide a review of hospitality and tourism studies that have used social media analytics to collect, examine, summarize and interpret “big data” derived from social media. It proposes improved approaches by documenting past and current analytic practice addressed by the selected studies in social media analytics.

Design/methodology/approach

Studies from the past 18 years were identified and collected from five international electronic bibliographic databases. Social media analytics-related terms and keywords in the titles, keywords or abstracts were used to identify relevant articles. Book chapters, conference papers and articles not written in English were excluded from analysis. The preferred reporting items for systematic reviews and meta-analyses (PRISMA) guided the search, and Stieglitz and Dang-Xuan’s (2013) social media analytics framework was adapted to categorize methods reported in each article.

Findings

The research purpose of each study was identified and categorized to better understand the questions social media analytics were being used to address, as well as the frequency of each method’s use. Since 2014, rapid growth of social media analytics was observed, along with an expanded use of multiple analytic methods, including accuracy testing. These factors suggest an increased commitment to and competency in conducting comprehensive and robust social media data analyses. Improved use of methods such as social network analysis, comparative analysis and trend analysis is recommended. Consumer-review networks and social networking sites were the main social media platforms from which data were gathered; simultaneous analysis of multi-platform/sources of data is recommended to improve validity and comprehensive understanding.

Originality/value

This is the first systematic literature review of the application of social media analytics in hospitality and tourism research. The study highlights advancements in social media analytics and recommends an expansion of approaches; common analytical methods such as text analysis and sentiment analysis should be supplemented by infrequently used approaches such as comparative analysis and spatial analysis.

Abstract

Purpose

The rise of cultural governance has made cultural democracy important in East Asia. South Korea and China have chosen to develop cultural democracy by means of developing community-based cultural houses. Cultural houses in Korea were first managed from the center but have now been decentralized, and those in China have been developed based on local financing and administration. Since central-local intergovernmental relations, as they relate to public culture, have gone untouched in East Asia, the purpose of this paper is to study how central-local intergovernmental relations have impacted the development of cultural democracy in this area, in order to better understand how public culture should be developed.

Design/methodology/approach

A comparative study of the cases of South Korea and China has been used. The materials and information collected for the study were gathered by a review and an analysis of extant literature, policy documents, data and other materials from the relevant departments of both countries. It was also based on semi-structured interviews conducted with the national cultural departments, regulatory institutions, and with officials and scholars.

Findings

This study shows that central-local intergovernmental relations can have an impact on the management of community-based cultural houses and the effectiveness of cultural democracy’s development. Only complete decentralization that directly invites democratization will provide positive local conditions for cultural democracy’s growth. In short, meaningful governmental responses to local demands and a strong civil society are critical for the advancement of cultural democracy.

Practical implications

This study seeks to provide insights into the relationship between central-local intergovernmental relations and cultural democracy. At the micro project level, cultural project management should be improved; at the medium local level, the public must be made part of any decentralization effort; and at the macro national level, the multiple impacts caused by decentralization need to be considered.

Originality/value

This study is unique in terms of both its research questions and its research area. Central-local intergovernmental relations, as they relate to public culture, have gone comparatively untouched, especially in the context of East Asia. It is in this context that studying how central-local intergovernmental relations impact the development of cultural democracy is worthwhile, in order to better understand how public culture has developed and will be developed in future. A comparative study of the cases of South Korea and China has been used to discover the impacts of different dimensions of central-local decentralization on cultural development.
