Abstract

Purpose

The purpose of this paper is to investigate the tribological properties of carbonized polydopamine/reduced graphene oxide (CPDA/rGO) composite coatings.

Design/methodology/approach

CPDA/rGO composite coatings were prepared using the spray technique and subsequent pyrolysis under argon. The transmission electron microscopy, field-emission scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy and Raman spectroscopy revealed the conversion of PDA and GO into CPDA and rGO, respectively.

Findings

The results of tribological investigations show that the CPDA/rGO composite coatings with heat treatment at 300°C possess much better friction-reduction and anti-wear properties.

Originality/value

The worn surfaces of the PDA/GO composite films after heat treatment at 300°C were much smoother than that of the copper substrate. The tribofilms containing C, N, O and Cu played an important role on reducing friction and increasing wear resistance.

Abstract

Purpose

This study aims to investigate the interactions between lean production, internal green practices, green product innovation and sustainable performance metrics. The study further looks at the mediation effect of internal green practices and green product innovation between lean production and sustainable performance dimensions.

Design/methodology/approach

The questionnaire was used to glean data from 209 manufacturing firms. All the hypothesized relationships were processed by using partial least square-structural equation modelling.

Findings

The results suggest that lean production significantly leads to the implementation of internal green practices and the production of quality products with eco-oriented features that meet customers’ needs. Further, while lean production and internal green practices were found to significantly influence sustainability performance, green product innovation significantly influences only financial performance. Besides, the mediation analysis shows that internal green practices mediate the relationship between lean production and sustainable performance dimensions but green product innovation mediates the relationship between lean production and financial performance only.

Research limitations/implications

The study is limited to firms from Ghana, a developing country; hence, the results cannot be imported to reflect other geographical contexts.

Practical implications

The results of the study provide sufficient justifications for managers, (especially Ghanaian managers and those from other similar environs) to commit their financial resources towards implementing lean production and internal green practices so as to achieve sustainability excellence.

Originality/value

This study magnifies and provides new insight on lean and green literature by developing a comprehensive research model that concurrently tests the direct and indirect effects between lean production, internal green practices, green product innovation and sustainable performance dimensions.

Abstract

Purpose

Science of the Crowd is a new paradigm. The research on the relationship between provision and requirement arising from the behavior of the crowd under the interconnected environment is a promising topic. This paper aims at studying a new type of interconnected architecture.

Design/methodology/approach

This study is a pioneer work on the establishment of a new type of interconnected architecture – rim chain. The rim chain aims at supporting prompt matching between provision and requirements.

Findings

The analytical results suggest that requirements can be fulfilled in accordance with six degrees of separation. In other words, the matching between the requirements and provision takes place with six hops in the rim chain framework.

Originality/value

Knowledge graph is used to implement the rim chain.

Abstract

Purpose

The purpose of this paper is to examine the usefulness of fusion as a means of improving the precision of automated opinion detection.

Design/methodology/approach

Five system fusion methods are proposed and tested using runs submitted by the Text REtrieval Conference (TREC) Blog06 participants as input. The methods include a voting method, an inverse rank method (IRM), a linear‐normalised score method and two weighted methods that use a weighted IRM score to rank the document.

Findings

Mean average precision (MAP) is used as an indicator of the performance of the runs in this study. The best system fusion method achieves a 55.5 percent higher MAP result compared with the highest MAP result of any individual run submitted by the Blog06 participants. This equates to an increase in detection of 2,398 relevant opinion documents (21 percent).

Practical implications

System fusion can be used to improve upon the results achieved by existing individual opinion detection systems. On the other hand, multiple opinion detection approaches can be combined into one system and fusion used to combine the results to build in diversity. Diversity within fusion inputs can increase the improvements achieved by fusion methods. The improved output from a diverse opinion detection system will then contain a higher number of relevant documents and reduce the incidence of high‐ranking non‐relevant documents and low‐ranking relevant documents.

Originality/value

The fusion methods proposed in this study demonstrate that simple fusion of opinion detection systems can improve performance.

Abstract

In China, the clothing industry, featured by labor-intensive operation and low added value, is facing a major challenge, namely how to change the pattern of China's clothing industry by means of technology, innovation, originality and so on, and mitigate inventory pressure. The Red Collar Group presented in this case not only realizes zero inventory, but also achieves a year-on-year growth of more than 150% of annual sales in 2015. All of this can be attributed to the Internet zero inventory and customization model which took 10 years to build up: Using new information technology, collect personalized and fragmented customer needs, and design a production module involving business process reengineering and IT/IS integration…

Abstract

To boost the fiscal revenue, i.e., government revenue over GDP and central government revenue over government total revenue, China conducted the 1994 fiscal reforms. According to some observers, the results of the initial reforms were mixed. This study reveals, contrary to most examinations of previous studies, the 1994 fiscal reforms have been an enormous success in achieving the original policy purposes, although remaining problems still present a daunting task for the Chinese government. This paper examines the factors triggering the 1994 fiscal reforms, reveals the contents and accomplishments of the reforms, explores unfinished tasks and ultimately proposes some policy implications.

Abstract

Purpose

The purpose of this paper is to examine the mediating role of immediate performance outcomes on the relationship between dimensions of supply chain integration (SCI) and financial performance.

Design/methodology/approach

This study tests the proposed model linking dimensions of SCI, immediate performance outcomes and financial performance using structural equation modeling on a sample of Indian manufacturing companies.

Findings

The findings suggest that the relationship between dimensions of SCI and firm performance is fully mediated through the immediate performance outcomes.

Originality/value

This study deals with the potential benefits of SCI, especially in developing countries like India, where a little research has been done in this area. Also, this study provides support to practitioners that SCI is an effective way of improving both supply chain performance and financial performance.

Abstract

This chapter examines the changing state–university–student relationships in post/socialist China since the late 1980s. We begin with an introduction to four salient themes in scholarship on Chinese post/socialism that are highly relevant to higher education: globalization, gradualism, civic society, and a critique of holism. These themes help us explain interrelated educational trends that affect the state–university–student relationship: the globalization, “massification,” and stratification of higher education; the redefined role of the state in university governance and management; higher education marketization and privatization; and the quest for meaning and (e)quality in and through higher education. Our general argument is that during the “socialist” period the main relationship central to higher learning was between the state and students. Universities were agents of the state; from a legal point of view, indeed, universities did not have an independent status from the state. In the “post-socialist” era the university–student relationship has become more significant. We examine this reconfiguration through two case studies, one on the development of college student grievance and rights consciousness, and the other on reforms in higher education student services administration. When looked at from the point of view of the state, we see that appropriation and implementation of policies and regulations shaping student rights and services are in partial contradiction with state policies to accelerate economic growth and bolster party authority. From the point of view of universities, we see institutions grappling with how to deliver on forward-looking structures and actions while navigating between the state's policy mandates and growing expectations and demands of its student and business stakeholders. From the point of view of students, we see how constrained agency, uncertainty, and the power of the credential motivates social praxis. At all levels of the state–institution–student relationship actors are employing a kind of pragmatic improvisation (one of the salient features of post/socialism) captured by the well-known Chinese proverb “groping for stones to cross the river.” This saying is an apt metaphor for the tentative searching by state, institution, and individual for a safe foothold in the post/socialist world.

Abstract

Purpose

With the focus on the impact of foreign direct investment (FDI) on export quality or of intellectual property rights (IPR) protection on export trade, there is little scholarly attention on how IPR protection affects the relationship between FDI and export quality. This study aims to examine the potential nonlinear dynamic threshold effect of IPR protection on the relationship between FDI and export quality. Distinguishing between developing and developed countries, the authors present an empirical analysis of the effects of FDI on export quality per degree of IPR protection.

Design/methodology/approach

Using panel data on 45 countries for the period from 1992 to 2014, we use a nonlinear dynamic panel threshold model to examine the effect of IPR protection on the relationship between FDI and export quality.

Findings

The authors find a triple threshold effect of IPR protection in both developing and developed countries. The three threshold values are larger for developed countries than for developing countries. The coefficients on the relationship between FDI and export quality per degree of IPR protection are larger in developing countries than in developed countries, except for high IPR protection. The results of the paper suggest that the effect of FDI on export quality differs greatly per degree of IPR protection. In both developing and developed countries, FDI impacts export quality most significantly under medium-high IPR protection. Having estimated the optimal range of IPR protection for attaining FDI in both groups of countries, policy recommendations are offered.

Originality/value

These findings not only contribute to the literature but also provide a view that a moderate level of IPR protection is conducive to attracting FDI and improving export quality.

Abstract

The greatest challenge facing most economies today is how to grow their economies and reduce over-dependence on imports in the midst of increasing integration of world economies. Addressing this challenge seems to be difficult despite all efforts by policymakers at different times to salvage the situation, the problem persists as evident in the global financial crisis of 2008 and the Eurozone crisis of 2012 which were generally viewed as a glaring illustration of limitless pursuit of economic integration and governance failure at the expense of carefulness, prudence, due diligence, and regulation. It also reflects the lack of proper coordination and lack of proper economic integration facing most emerging market economies of the world. Against this background, this study focuses on the reexamination of the impact of trade openness (TOP) and financial openness (FOP) on economic growth in emerging market economies. The direct and interaction effect of the both openness variables on economic growth in these markets is investigated using data from 2000 to 2017 adopted from World Development indicators of the World Bank. Over 30 emerging market economies covering Asia, Latin America, and Europe are included in the study. For empirical analysis, the study uses one measure of FOP: de facto (total capital flow) variables following Aizenman and Noy (2009) and a measure of TOP as total trade–GDP ratio. The study applies the Dynamic Panel Approach, that is, the Arellano–Bond GMM estimation technique and Granger Causality Test to address the objectives. The results of this study show that TOP has a positive and significant impact on all the countries studied, whereas FOP has positive but no significant impact on economic growth of these countries, implying that these countries have not harnessed the benefit of financial liberalization and integration. It is recommended that the emerging market economies should open not only their economies to trade but also open their economies to finance so as to reap the benefits of FOP and integration.
