Abstract

Purpose

The purpose of this paper is to adopt fuzzy interpretive structural modeling (ISM) to develop a precise evaluation framework and provide a theoretical basis for enhancing the understanding of responsible consumption and production (RCP) in academic and industrial fields.

Design/methodology/approach

An integration of fuzzy set theory and ISM is proposed to maintain a higher level of consistency and reduce the uncertainty inherent in expert responses.

Findings

RCP can be categorized into seven levels, which represent the driving power from higher to lower. The top aspect is management style; the remaining aspects are stakeholder management, regulation compliance, efficiency improvement, sustainable awareness, sustainable production and social responsibility.

Research limitations/implications

This study attempts to integrate the triple bottom line (TBL) concept and corporate sustainability to develop a significant framework for evaluating RCP. Although the proposed aspects and criteria can be used to evaluate the Chinese construction industry, these may be insufficient for other industries. In addition, further discussion regarding important aspects and criteria is required to complete the theoretical basis.

Practical implications

The results indicate that the top two criteria are establishing transparent communication channels and promoting managerial attitudes and behavior, which are followed by technology capabilities, organizational culture and stakeholder engagement. These five criteria play important roles when implementing RCP practices among Chinese construction firms.

Originality/value

This study is the first to discuss RCP via an integration of the TBL concept and corporate sustainability. The framework developed herein provides a precise guideline for Chinese construction firms to improve their performance, and it also promotes the efficient use of resources via sustainable practices.

Abstract

Purpose

Wearable electronic devices have emerged which require compact, flexible power storage devices such as batteries and supercapacitors. Recently, energy storage devices have been developed based on supercapacitor threads. However, current supercapacitor energy storage threads which use electrolytes based on aqueous gels have a 1 V potential window. This is much lower than the voltage required by most electronic devices. This current contribution presents an approach for fabricating a multilayer supercapacitor working as a circuit unit, in which series combinations of the multiple layer structures can achieve a higher potential window, which can better meet the needs of wearable electronic devices.

Design/methodology/approach

Two-capacitive layer thread supercapacitors were fabricated using a semi-automatic dip coating method by coating two capacitive layers sequentially on a 50 μm stainless steel core wire, each capacitive layer includes ink, aqueous-based gel electrolyte and silver conductive paint layers.

Findings

Two capacitive layers of the single thread supercapacitor can work independently, or as combination circuits – parallel and series. Cyclic voltammograms showed that all flexible circuits have high electrochemical stability. For the case of series circuit configuration, with H3PO-polyvinyl alcohol (PVA) gel electrolyte, a working potential window of 2 V was achieved.

Originality/value

A flexible single thread supercapacitor of multilayer structure, with working voltage above 1 V in H3PO4-PVA gel electrolyte, has not been reported before. A semi-automatic dip coating setup used to process the thread supercapacitor has high potential for transfer to an industrial environment for mass production.

Abstract

Purpose

The main aim of this study is to examine the behavior of reinforced concrete short columns strengthened using longitudinal near surface mounted (NSM)-carbon fiber reinforced polymer (CFRP) strips.

Design/methodology/approach

A full 3D-finite element (FE) model was developed using ABAQUS in order to conduct the analysis. The model is first validated based on experimental data available in the literature, and then the effect of concrete compressive strength, number of CFRP strips that are used and the spacing between them were taken in consideration for both concentric and eccentric loading cases. The parametric study specimens were divided into three groups. The first group consisted of unstrengthened columns and served as control specimens. The second group consisted of columns strengthened by longitudinal CFRP strips at two opposite column faces.

Findings

The results of this study are used to develop interaction diagrams for CFRP-strengthened short columns and to develop best-fit equations to estimate the nominal axial load and moment capacities for these strengthened columns. The results showed that the specimens that were strengthened using more longitudinal CFRP strips showed a significant increase in axial load capacity and a significant improvement in the interaction diagram, especially at large load eccentricity values. This result can be justified by the fact that longitudinal strips effectively resist the bending moment that is generated due to eccentric loading. Generally, the process of strengthening using longitudinal strips only has a reasonable effect and it can be typically considered an excellent choice considering the economic aspect when the budget of strengthening is limited.

Originality/value

This research aims at studying the performance of strengthened rectangular reinforced concrete short columns with CFRP strips using FE method, developing interaction diagrams of strengthened columns in order to investigate the effect of different parameters such as compressive strength (20, 30 and 40 MPa), number of CFRP strips (1, 2, 3 and 4) and the spacing between CFRP strips in terms of the ratio of CFRP center point distance to column outside dimension ratio (0.60, 0.70 and 0.80) on the behavior of strengthened RC columns and improving empirical formulas to predict the nominal axial load and moment capacities of strengthened RC columns. These parameters that directly affect short column load carrying capacity are presented in ACI-318 (2014).

Abstract

Purpose

In today's competitive environment, sustainability is talked out in every sphere of life. Sustainability is a key to stability and for that roots are being focused by incorporating sustainability in higher education. The basic purpose of this paper is to prioritize the sustainability drivers in the higher education system. This research will provide fruitful insight into the sustainability drivers in the higher education system to the education industry and policymakers.

Design/methodology/approach

The present research is conducted on the 400 students studying in four major universities in the state of Punjab. Fuzzy analytical hierarchy process was applied to prioritize the sustainability drivers in the higher education system. The primary factors considered for the present study include social-people (social responsibility), environmental-planet (sustainable environmental practices) and financial-profit (economic value created).

Findings

The most influential criteria were environmental-planet (sustainable environmental practices) and social-people (social responsibility). The five most influential subcriteria were “Student engagement in eco co-curricular activities (C21)”, Energy efficiency measures (C23)”, “The HEI as a job driver in the city (C11)”, “Total direct energy consumption (C31)” and “Support from the HEI for local initiatives and help in growing the sustainability of the community or region (C12)”.

Research limitations/implications

Although the sample survey conducted in this study was focused on a small sample selected from the state of Punjab which genuinely represented the total population, it is still considered as a limitation for the present study.

Practical implications

The outcome of this research provides policymakers with a better understanding of the sustainability drivers in higher education. This will further help them toward achieving the aim of sustainability.

Originality/value

The present research is based on the available literature on sustainability and the results of the study would add value to the existing knowledge base.

Abstract

Purpose

The objective of this study is to assess whether pro-health herbal probiotics, ascorbic acid and allicin added to the finishing diets of hybrid pig influenced the intramuscular fat (IMF) content in longissimus lumborum (LL) muscle, the fatty acid profile and lipid quality indices, as it has an impact on human health.

Design/methodology/approach

After 80 days of equal fattening, the pigs were divided into the control group (CT, n = 30 received commercially allowed and applicable antibiotics) and the experimental group (EX, n = 30), which until 95 days of rearing were supplied with fermented herbs extract (FHE Multikraft® Austria) with probiotics Saccharomyces cerevisiae, Lactobacillus casei, Lactobacillus plantarum, L-ascorbic acid and extract of garlic (10% allicin). After slaughter, crude fat content and fatty acid profile were determined in LL muscle samples, and on that basis lipid indices were calculated.

Findings

Supplementation with FHE, probiotics, L-ascorbic acid and allicin has significantly impacted the crude fat content in the meat and the percentage of fatty acids content: tricosanoic (C23:0), heptadecanoid (C17:1 n-7), eicosanic (C22:1 11cis n-9) and eicosatrienoic (C20:3 11cis n-3), in comparison to CT group. Amongst lipid quality indices, IMF in LL of pigs from EX group, the C18:2 n-6/C18:3 n-3 ratio is characterised by a significantly higher value and thus is more beneficial to the health of the consumer.

Originality/value

The authors have indicated that using FHE, probiotic supplements with ascorbic acid and allicin in commercial fattening of pigs, as an alternative for antibiotic growth promoters (AGP), improves the fatty acid profile of the meat.

Abstract

Purpose

This study establishes a set of seafood processing circular supply chain capabilities (CSCCs) in Vietnam using qualitative data analytics. This study specifies the interrelationships and hierarchical structure comprising six aspects and 24 criteria for the seafood processing circular supply chain in Vietnam.

Design/methodology/approach

Fuzzy Delphi method is used to confirm the validity. Fuzzy set theory is used to deal with the complexity and uncertainties from the qualitative information. The decision-making trial and evaluation laboratory method is used to examine the interrelationships among attributes. The analytical network process segregates (or displays) the capabilities in a hierarchical structure.

Findings

The results show that management control and technological capability dominate in circular design, circular sourcing, circular production and resource recovery. In practices, the strategic planning, action planning, information technology and technological facilities are important to seafood processing industry.

Originality/value

The CSCCs are pivotal in establishing a concrete foundation for the execution of circular supply chain management, with the aim of optimizing resource utilization and eliminating waste; however, prior studies have lacked a focus on the capability associated interrelationships and hierarchical structure in qualitative data analytics.

Abstract

Purpose

The purpose of this paper is to calculate regional contents in the exports of the major regional blocs to the world, Trans-Pacific Strategic Economic Partnership (TPP), and Regional Comprehensive Economic Partnership (RCEP), respectively, to find the backward trade linkages between them instead of normal forward linkages.

Design/methodology/approach

To calculate “a region” content in intermediate and value-added exports, this paper uses OECD’s inter-country input-output table (ICIOT), and tries to decompose the contents of trade. Using the information of ICIOT, Koopman et al. (2014) and Wang et al. (2013) decompose gross exports of a country’s exports.

Findings

TPP is a loosely tied bloc featured by openness to the Asia-Pacific region. Trade linkages between members are stronger in RCEP than those in TPP, particularly in the trade of intermediate goods. Trades in RCEP are closely connected to exports to TPP, but the opposite direction is not clear.

Research limitations/implications

First of all, the recent base year of the data on value added in trade is 2011, which can be regarded as a little bit out of date. Therefore, it should be cautious in interpreting the results in that it may not reflect the characteristics of current trade. Second, this paper uses ICOIT instead of world input-output table.

Practical implications

A large portion of trades in RCEP and TPP is triggered by a global production network (fragmentation, vertical specialization), different from traditional trade focusing on inter-industry trade or competition between countries. Thus, the formation of TPP or RCEP is predicted to stimulate trade of the other instead of discriminating nonmember countries.

Social implications

In particular, the authors have special concern in the backward linkages between RCEP and TPP, the distinct characteristics of the two regional blocs and, finally, major countries’ preferences of the one over the other and industrial conflicts toward TPP or RCEP even in an economy.

Originality/value

Although this paper uses the approach by Baldwin and Lopez-Gonzalez, this paper is the first research on the analysis of the export contents in major trading blocs in the Asia-Pacific region.

Abstract

Purpose

The purpose of this paper is to verify a possible relationship between quality management system certification according to ISO 9001 standard and risk of failure of Italian companies.

Design/methodology/approach

A synthetic index which summarize the most crucial economic/financial aspects of the studied companies is assumed as the response variable of a statistical model for studying the effects of four specific factors: certification, company size, regional development and manufacturing sub-sector. The analysis is conducted on a sample of Italian companies belonging to different manufacturing sub-sectors. The used data are obtained from the database Aida® by Bureau van Dijk and from the database of the Italian accreditation body Accredia. The study is based on analysis of variance (ANOVA) and contingency tables.

Findings

Preliminary results of ANOVA show that only company size, regional development and manufacturing sub-sector can be considered fully significant. Furthermore, the major conclusion from the analysis of contingency tables is that ISO 9001 certification is connected to the legal status (active, not active) of a company only for a portion for the studied manufacturing sub-sectors. Hence, the scenario is quite variegated and a significant positive interaction between certification and corporate performance is not always confirmed.

Research limitations/implications

Although the research shows some interesting results, it is liable to extensions and improvements. In particular, at the current exploratory level, it is limited to a specific period of time and considers only the Italian sector, but it could be extended to a wider number of years and to European and international level.

Practical implications

The study opens a way for a number of important questions about the meaning, usefulness and effectiveness of ISO 9001 certification. In particular, it may be time to ask whether the paradigm of certification actually needs a radical rethink.

Originality/value

This work represents a first exploratory attempt to correlate the risk of failure with the achievement of ISO 9001 certification. There are several similar works in literature which, however, focus mainly on sectorial aspects of the corporate background.
