Abstract

Purpose

This paper aims to evaluate the progress made in understanding the impact of multi-level institutions on entrepreneurship.

Design/methodology/approach

Based on scientific articles published between 1992 and 2017, the authors take a unique focus on both institutional theory applied and research topics of this area. Bibliometric method and systematic literature review method are used.

Findings

The results demonstrate that although institutional theory is well prepared for entrepreneurship context operating at different levels, the major knowledge foundation used predominantly focuses on macro and meso level. When it comes to research topics, entrepreneurship is often simplified as the founding of new venture, and the unique venture founding process has rarely been explored.

Originality/value

This paper is the first to provide a full picture of the multi-level institutions and their consequences on different kinds of entrepreneurial activities. The authors’evaluation of this research area also points out directions for future study.

Abstract

Purpose

Digital library sampling is used to obtain a collection of random literature records from the backend database, which is a crucial issue for a variety of important purposes in many online digital library applications. Digital libraries can only be accessed through their query interfaces. The challenge is how to ensure the randomness of the sample via the autonomous query interface.

Design/methodology/approach

This paper presents an iterative and incremental approach to obtain samples through the query interface of a digital library. In the approach, a novel graph model, query-related graph, is proposed to transform the flat literature records into a graph structure, and samples are obtained iteratively by traveling the query-related graph. Besides query-related graph, the key components, query generation, termination condition and amending deviation, are also discussed in detail.

Findings

The extensive experiments over two real digital libraries, ISTIC and IEEE Xplore, show the proposed approach results in a better performance. First, the approach is very effective to obtain high-quality samples which are evaluated by the measure “sample deviation.” Second, the sampling process is very efficient by only submitting fewer random queries. Third, the approach is robust.

Research limitations/implications

This sampling approach is limited by the query interfaces on a web page. In rare cases (<3 per cent), this approach cannot access query interfaces by sophisticated techniques.

Practical implications

Digital library sampling is very useful for a variety of important purposes: subject distribution analysis, literature quality evaluation, digital library size estimation, source selection in digital library integration and content freshness evaluation.

Social implications

Myriads of online digital libraries can be accessed online. Digital library sampling is a useful way to understand digital libraries for many important applications.

Originality/value

Most of the attributes of a digital library query interface have infinite values, such as keyword attributes, which cannot be handled effectively by the existing sampling approaches.

Abstract

Purpose

In China the maturity of the industrial development has the demonstration and reference implications for how to achieve enterprises competitiveness among the developing industries in a country. With the development of globalization, how to improve the enterprises competitiveness has became a serious problem to be solved for Chinese enterprises. The management innovation is reasonable and appropriate to solve this problem. Compared with the independent innovation, adoptive management innovation has become the main way for enterprises to fulfill the management innovation and change the management styles under the open economy condition. The research strives to reveal the “black box” in the management innovation adoptive process and give an answer to a series of questions, such as “what is the role of entrepreneurs in management innovation adoptive process?”

Design/methodology/approach

Exploratory case study approach is taken to find the entrepreneurs' role in management innovation adoptive process of Chinese traditional industry.

Findings

This paper constructs the adoptive management innovation model from three dimensions, using exploratory case technique, which explores the key factors and mechanism of realizing management innovation adoption. Through the exploratory case analysis to verify the viewpoint which is proposed by the model: entrepreneurs played a leading role in the adoptive management innovation of non‐procedural process, and the role is the result of the mixed function of the external and internal environment. Entrepreneurs analyze and explore the new problems and opportunities, and their own experience and ability determine the cognition and explore degree towards these problems directly; entrepreneurs' integration ability of resources can be approved and accepted after the new practice has been proposed and become mature. Entrepreneur long‐term shaping on organizational resources determines whether the management innovations introduction would be really integrated into enterprise management system. The entrepreneur's typical behavior on “integration, learning and shaping” is the foundation and guarantee of adoptive management innovation, which have connective effect on adjacent stages.

Originality/value

The article describes Haier BPR process of adoptive management innovation and the adoptive management innovation mode, and analyzes the effect of entrepreneurs' role on adoptive management innovation of China's color TV industry. The Chinese color TV industry as the maturity industry has the demonstration and reference implications for how to achieve enterprises competitiveness in Chinese developing industries.

Abstract

Purpose

The color TV industry in China has become a mature industry. Its development demonstrates and provides reference implications for how developing industries within a country can achieve a technological leap. This paper aims to address this issue.

Design/methodology/approach

An exploratory case study approach is taken to find the key factors in the technological catch‐up of China's traditional industry.

Findings

In the study it is found that China's color TV industry, as a mature traditional industry, has four‐dimensional key factors affecting the catch‐up of technology in the flat‐panel stage: market; merger and acquisition; international cooperation innovation for patent; and the roles of internal reform. “Market” is the window of opportunity and challenge; “merger and acquisition” is the key factor for making the patent convert from external mode to internal mode by deviant‐track. The “international cooperation innovation for patent” is also a key factor to ensure achievement of technology catch‐up and sustainable technological innovation. The role of internal reform promoter is the key factor in the technological catch‐up process in which taking entrepreneur as the core.

Originality/value

Abstract

Purpose

The purpose of this paper is to study the influence of different trade modes on the electricity market.

Design/methodology/approach

A linear model between power units' output and their bidding prices is presented and optimal models to minimize the purchase power cost of power grid companies are presented, applying static games and dynamic games, respectively. Then the relation between power generation amount and units' bidding price is settled by using difference methods. In addition, optimization models are established to optimize profits of units at discriminatory bidding or uniform marginal price applying static game and dynamic game. Finally, the economic benefits and fair competition are compared and analyzed.

Findings

If impartiality is emphasized, the detailed history bidding information should not be opened. Also, it is fairer but difficult to control units' speculative behavior at uniform marginal price.

Research limitations/implications

A supposition has been made that all participants are rational.

Practical implications

The paper presents useful advice for improving the trade mode of the electricity market.

Originality/value

Power units' bidding models and strategies are presented at discriminatory bidding price or at uniform marginal price applying non‐cooperation static game and dynamic game, respectively.

Abstract

Purpose

The purpose of this paper is to assess the trends and practices of consumers buying their products online and offline. Further, it also analyses the factors which influence consumers to go online and offline for their purchases.

Design/methodology/approach

To analyse the factors influencing consumer’s buying behaviour, 18 variables have been identified and questionnaire using a seven-point scale (where 1 indicating very unimportant and 7 very important) was designed. It was circulated among 875 consumers residing in Delhi and National Capital Region between February 2012 and April 2012, who buy offline or online or from both sources. The responses so collected have been tabulated and analysed with the help of a factor analysis method. The principal component method has been used to determine the minimum number of factors that would account for the maximum variance in the data collected. The data have been analysed by using SPSS version 19.

Findings

The study identifies Factor 1 (F1) as a Pre-sales Offer which includes the following variables that influence consumers mostly: less price, special sales, rebates and coupons, easy to get product information, physical examination of product, immediate possession of a product, uncertainty about getting the right item, accept all forms of payment and helpfulness of sales people. Thereafter, the study identifies Factor 2 (F2) as Better Assortment and After Sales Policy which includes the following variables: brand selection and variety, post-purchase service, exchange refund policy, quality of merchandise, availability of products in stock and ability to compare products. Finally, it identifies Factor 3 (F3) as Product and Its Importance which includes the following variables: speed of selection and purchase, social and family experience, shipping and handling charges and easy browsing of the products which influence consumer behaviour.

Research limitations/implications

The findings of this study are purely based on the information provided by the respondents. The sample forms little part of the total population.

Originality/value

Though online retailing in India is in nascent stage, yet it has shown its presence. To sustain and grow in a competition, the retailers need to understand the purchasing behaviour and factors influencing purchase behaviour of consumers. The behaviour of consumers is unpredictable and dynamic. The study suggests offline and online retailers to adopt policies or strategies after considering three factors extracted from the study to attract and retain consumers to their stores. Further, it also provides ideas to consumers to choose their retailers on comparative advantages basis.

Abstract

Purpose

The present contribution is in the field of quantum modelling of macroscopic phenomena. The focus is on one enigmatic aspect of quantum physics, namely, the Einstein–Podolsky–Rosen paradox and entanglement. After a review of the state-of-the-art concerning macroscopic quantum effects and quantum interaction, this paper aims to propose a link between embryology and acupuncture in the framework of macroscopic intricate states induced by quantum mechanics.

Design/methodology/approach

The author uses the fractaquantum hypothesis which supposes that the quantum framework is applicable to all insecable elements in nature, whatever their size.

Findings

This contribution considers an open question related to a possible link between acupuncture and embryology: can a weak form of intrication be maintained during stem cell division to interpret the acupuncture meridians as an explicit manifestation of a macroscopic intricate system? The macroscopic structure suggested by quantum mechanics could be a beginning of explanation of acupuncture through the embryologic development.

Research limitations/implications

A fundamental hypothesis is the fact that during cell division, cells keep some weak intrication.

Practical implications

This contribution suggests a structure of the acupuncture meridians. The links between the acupuncture points have to be searched in the embryologic development of the individual through a weak remaing intrication of some of his cells and not in present explicit relations.

Social implications

A new link between occidental and oriental cultures is explored.

Originality/value

This contribution suggests conceptual links between acupuncture, embryology and macroscopic intricate states.

Abstract

Purpose

Micro-video platforms have gained attention in recent years and have also become an important new channel for merchants to advertise their products. Since little research has studied micro-video advertising, this paper aims to fill the research gap by exploring the determinants of micro-video advertising clicks. We form a micro-video advertising click prediction model and demonstrate the effectiveness of the multimodal information extracted from the advertisement producers, commodities being sold and micro-video contents in the prediction task.

Design/methodology/approach

A multimodal analysis framework was conducted based on real-world micro-video advertisement datasets. To better capture the relations between different modalities, we adopt a cooperative learning model to predict the advertising clicks.

Findings

The experimental results show that the features extracted from different data sources can improve the prediction performance. Furthermore, the combination of different modal features (visual, acoustic, textual and numerical) is also worth studying. Compared to classical baseline models, the proposed cooperative learning model significantly outperforms the prediction results, which demonstrates that the relations between modalities are also important in advertising micro-video generation.

Originality/value

To the best of our knowledge, this is the first study analysing micro-video advertising effects. With the help of our advertising click prediction model, advertisement producers (merchants or their partners) can benefit from generating more effective micro-video advertisements. Furthermore, micro-video platforms can apply our prediction results to optimise their advertisement allocation algorithm and better manage network traffic. This research can be of great help for more effective development of the micro-video advertisement industry.

Abstract

Purpose

This paper aims to present the potential of using aligned single-layer graphene sheets to reinforce the methyl methacrylate cantilever beam in low-velocity impact problem.

Design/methodology/approach

The Halpin–Tsai law is applied to compute the mechanical properties of isotropic polymer beam reinforced by aligned graphene sheet. Using both longitudinal and lateral displacements in composite beam, all components of the stress and strain fields are written. The equations of motion are derived by applying energy method, generalized Lagrange equations and Ritz method.

Findings

The analytical formulation accuracy is corroborated by comparing the present results with those available in the literature. Numerical examples indicate that the contact duration is decreased with increasing of graphene volume fraction, whereas the values of peak contact force, shear strain and shear stress at peak contact force tend to be vice versa. Also, among the results, shear stress at the peak contact force has the most effect with graphene volume fraction changes.

Originality/value

This research fulfils an identified need to investigate how graphene-reinforced beam behavior subjected to low-velocity impact can be enabled.
