Abstract

Purpose

This paper aims to develop a new multi-fiber element for predicting the structural behavior of planar-reinforced concrete (RC) members.

Design/methodology/approach

In this work, an exact multi-directional stiffness matrix is analytically derived based on the post-cracking bond-slip interaction between concrete and steel bars. The approach is also extended for large displacement analysis using Green–Lagrange finite strain tensor. In the proposed formulation, the weak form of governed differential equations is approximated by a trial-function expansion based on a finite strain-description and an additional degree of freedom for steel bars.

Findings

The findings provide a realistic description of cracking in the concrete structure. Numerical studies are conducted to examine the accuracy of the suggested approach and its capability to predict fairly complex responses of RC models. The findings prove that the proposed element can evaluate local and global responses of RC members, and it can be used as a reliable tool to reflect bond-slip effects in large displacement level. This leads to a robust and precise model for non-linear analysis of RC structures.

Originality/value

The methodology is capable of simulating coupled inelastic shear-flexural behavior of RC members through local stress field theory and Timoshenko beam model.

Abstract

Purpose

The purpose of this paper is to report on the use of a combination of selective laser sintering (SLS) and vacuum casting to create plastic composites made by additive manufacturing.

Design/methodology/approach

The research has been carried out by approaching a new concept of the final part consistent in a plastic component, where the main body is made by SLS and the internal long fibres for reinforcing are made by vacuum casting of high-resistance epoxy resin. The part is designed for optimal number and distribution of the internal fibres taking into account the target relative stiffness (N/mm*kg). The methodology is applied to a pedal clutch of a car which has been tested in an equipment for fatigue and durability, being compared to the correspondent design for injection moulding.

Findings

Research has proven that the approach introduces relevant improvement in mechanical properties of the base resin consistent in PA 3200GF (EOS), reinforced by internal long fibres of resin VG SP5. Experiments showed significant increase of stiffness in the pedal clutch made under this procedure, where the stiffness was 77 per cent higher than the conventional SLS part and only 11.7 per cent lower than the one made by injection moulding of PA 66 with 50 per cent fibreglass.

Originality/value

The developed method introduces an alternative procedure for increasing the mechanical properties of plastic parts developed in SLS. Optimal orientation and distribution of long fibres clearly achieves better mechanical properties at low cost.

Abstract

Purpose

The purpose of this paper is to present a new bond slip model for reinforced concrete structures. It consists in an interface element (3D) which represents the interface between concrete (modeled in 3D) and steel, modeled using 1D truss elements.

Design/methodology/approach

The formulation of the interface element is presented and verified through a comparison with an analytical solution on an academic case. Finally, the model is compared with experimental results on a reinforced concrete tie.

Findings

Contrary to the classical perfect or “no-slip” relation which supposes the same displacement between steel and concrete, the proposed model is able to reproduce both global (force-displacement curve) and local (crack openings) results.

Originality/value

The proposed approach, applicable to large-scale computations, represents a valuable alternative to the no-slip relation hypothesis to correctly capture the crack properties of reinforced concrete structures.

Abstract

Purpose

Dependence on access to European markets through subcontracting relationships with European firms has exposed subcontracting clothing and textile producers in less developed economies to the vagaries of international market competition. This paper aims to examine the problems that such exposure creates and the requirements for developing marketing activities through the concept of the alliance life cycle as a viable solution for a sample of Tunisian clothing and textile firms.

Design/methodology/approach

The inductive reasoning of this research was implemented through qualitative research based on a range of tools derived from a case study and a dual ethnographic approach.

Findings

The main results showed that life cycle stages of the subcontracting firms reflected Schumpeter's creation and destruction cycle of innovation. Therefore, subcontracting firms could learn from their activities with their business customers so that they developed marketing competences in innovative processes. The findings also demonstrated that some of the firms in the Tunisian clothing and textile industries were more successful than others.

Research limitations/implications

This research focused mainly on subcontracting alliances with implications for future study of other alliances for different industries.

Practical implications

The life cycle approach could be of great interest to subcontracting managers in the post Multi Fibre Arrangement era. This approach is relevant mainly for decision makers in providing them with a framework within which they might optimise their marketing strategies and their implementations.

Originality/value

The research originality resides in its Schumpeterian perspective in considering business‐to‐business relationships. The value of the paper is to focus on the evolutionary aspects of relationships between contractors and subcontractors and the patterns of the marketing development within these relationships.

Abstract

Purpose

The Canadian apparel industry has long been challenged by imports from low-wage countries while its exports have declined since their height in 2002. This situation was exacerbated with trade liberalisation, which started in January 2005. Data from Industry Canada and a number of studies, amongst which those of the Apparel Human Resources Council (AHRC), showing the adverse effects of trade liberalisation since the phasing out of the multi-fibre agreement in 2005, the lack of competitive advantage for Canada as an apparel manufacturing nation and the subsequent rapid decline of its apparel industry, pointed to the need for a strategic response from the Canadian apparel industry, particularly from small to medium-sized enterprises. A study conducted for the AHRC of the Federal Government of Canada outlined a number of strategies that Canadian apparel companies could pursue, focusing on elements other than manufacturing in the traditional apparel value chain. These strategies seemed to suggest the implementation of a cluster approach where greater cooperation between suppliers would be required throughout the supply chain with a focus on functional expertise and relationships. The purpose of this paper is to determine whether a cluster strategy is being applied or if indeed it is applicable to Canada’s apparel companies.

Design/methodology/approach

A literature search, was undertaken to find the options available for the organisation of SMEs so that: an analytical framework could be created from the various theories and concepts that; would enable the evidence-based selection of an option or options suitable for adoption by Canadian apparel SMEs, to assist them to be more effective than stand-alone enterprises. Data were collected from case studies of Canadian apparel companies, an Experience Survey (conducted through face-to-face interviews with the directors of the AHRC, the Canadian Apparel Federation, Industry Canada, and Canadian retail and apparel supply executives) and from the responses to an online questionnaire sent to Canadian apparel suppliers. The data were subjected to examination using the analytical framework to determine whether the evidence existed on which to base a cluster-based strategic response to competition from overseas apparel suppliers, or whether one of the alternative options might be a more suitable match with the Canadian apparel business environment.

Findings

Neither the case studies nor the Experience Survey revealed sufficient evidence of open communication or of cooperation among suppliers in areas that would fortify horizontal clustering amongst apparel SMEs, such as the sharing of labour, market research or supply chain management; similar findings emerged from the online questionnaire sent to Canadian apparel suppliers, which showed little evidence favouring cluster development as a strategic response for the Canadian apparel supply industry. The research also showed that industrialists, experts and government advisors all recognised that, beginning with trade liberalisation in 2005, there had been a transformation of the Canadian apparel industry from a manufacturing to a service industry with the retailers taking much stronger control of the supply chain than before, which, taken together with the lack of open communication or cooperation among apparel suppliers gives rise to conditions which favour collaboration over clustering.

Originality/value

The paper provides a firm evidence base upon which to develop a different strategy for Canadian SMEs than the cluster approach that has been proposed to date. The findings reported in this paper show that Canadian apparel industry leaders, government and industry-led support organisations, retailers and suppliers all recognise that the type of open communication or of cooperation among suppliers in areas that would fortify horizontal clustering amongst apparel SMEs, such as the sharing of labour, market research or supply chain management does not occur to a sufficient extent to support the adoption of a cluster strategy by the Canadian apparel sector (although it may be applicable in Quebec). Canadian retailers have now taken the leading role in the supplier/retailer relationship. Any future strategy will need to take account of this repositioning of retailers and be centred upon vertical relationships between individual apparel suppliers and retailers.

Abstract

Purpose

The purpose of this study is to comprehend the efficiency levels of the Indian textile industry and also its sub-sectors in the light of changing global and national business environment. It is imperative to study the efficiency levels of textile industry for an emerging economy like India, where the industry contributes up to 13 per cent in export earnings, 10 per cent in total industrial production and 2 per cent in gross domestic product (GDP). The study holds an important place in the wake of phasing out of the quota regime existing under the Multi Fibre Agreement (MFA) and the rising competition being faced from countries such as Bangladesh, Vietnam and Cambodia.

Design/methodology/approach

The present study attempts to have an in-depth analysis of the efficiency levels in the Indian textile industry using meta-frontier data envelopment analysis, which is a non-parametric linear programming based frontier technique.

Findings

The findings highlight that the Indian textile industry is inefficient and has a huge scope of improvement in terms of efficiency. It also confirms the existence of different production functions among the sub-sectors of the industry. Among the different sub-sectors, the proximity of production frontier of readymade garments is the closest to meta-frontier followed by cotton and blended yarn, man-made fibre, cloth and others.

Practical implications

The findings bear strong implications for the policymakers in their attempt to regain the lost competitive position of the Indian textile industry and to enhance its contribution in the economy. As per the findings, policymakers should target the relatively inefficient sub-sectors of textile industry (cloth, man-made fibre, cotton and blended yarn) to infuse more efficiency in these sectors to enhance the market share of the Indian textile industry in the global textiles market.

Originality/value

The current study is a unique addition to the sparse literature on managing efficiencies in the textile industry, particularly of emerging economy like India. Looking at the methodological and geographical coverage of the previous work, it was found that no study has explored and analysed the efficiencies of the sub-sectors in the Indian textile industry using meta-frontier analysis. Therefore, this study will be the first of its kind which seeks to fill such gaps and intends to enrich the available literature.

Abstract

Purpose

The purpose of this study is to investigate the possibility of dyeing polyester (PET) fabric with natural dye extracted from annatto seeds using high temperature dyeing method.

Design/methodology/approach

PET fabric was dyed with annatto extract by varying dyeing parameters (temperature, time, pH and dye concentration) to determine the optimum dyeing conditions. The influences of KAl(SO4)2, FeSO4, gallnut mordants or a commercial UV absorber on colour yield and fastness properties were further studied.

Findings

Optimum results were obtained when the fabric was dyed at 130°C for 30 min in a dyebath containing 15 per cent (owf) annatto dye at pH 6. The dyed fabric had an orange shade and exhibited good to excellent wash, crock, perspiration fastness and fair light fastness. Further dyeing with mordants or UV absorber mostly resulted in lower colour yield and similar fastness properties.

Research limitations/implications

Although the light fastness was slightly improved to moderate level for the sample with UV absorber, a noticeable colour staining on cotton portion of multi-fibre fabric occurred when subjected to standard washing test. Compared to C.I. Disperse Orange 73, the annatto dye exhibited comparable colour fastness but had inferior light fastness when dyed at approximately the same colour strength.

Originality/value

Natural colourants from annatto seeds can be used to dye PET fabric at high temperature without mordants, yielding deep orange shade and satisfactory fastness properties. This study provides a promising application to reduce the environmental impact of synthetic dyes.

Abstract

Purpose

The purpose of this paper is to investigate the characteristics of the ex-garment workers that have turned to self-employment either in the formal or informal sector in the wake of the termination of the multi-fibre arrangement, which led to job losses. This move has given rise to a new community of entrepreneurs in the Mauritian landscape. Hence, this paper tells a story of women empowerment to disempowerment and finally the struggle for them to get re-empowered. This study also shows that there has been a limit to which self-employment led to empowerment for these women as their incomes are low, and they remain in vulnerable positions.

Design/methodology/approach

The study analyses the transformation of a sample of ex-garment workers into new entrepreneurs. The analysis in this paper rests on survey data collected from 92 ex-garment female workers, who are presently self-employed in either the formal or informal sectors, in different parts of Mauritius.

Findings

The findings reveal that the self-employed women in the sample, who are also ex-garment female workers, are essentially necessity-driven entrepreneurs. Most of them have only basic primary education and seem to have no other choice than to engage either formally or informally in similar activities, given their prior knowledge and experience in the textile and clothing industries. The authors also find evidence of statistically significant differences across age, marital status and household size between those women in the informal sector compared to those engaged in the formal sector.

Research limitations/implications

Resource constraints aside, this study could benefit from a larger sample cutting across many other sub-sectors. So far, the results of this study are only applicable to the specific sample studied. In terms of implications, the study finds that the relevant authorities should come up with targeted policies to help these women and address and alleviate the barriers that they face.

Practical implications

This study provides an insight to help explain why a large group of women have gone into self-employment in Mauritius in the past 10 years. The authors find that self-employment has provided an empowerment outlet for these women so that they can financially contribute to their household income. From the policy-making perspective, this implies that it is important for the government to support the activities of these self-employed women with conducive policies.

Originality/value

The study helps to advance knowledge on self-employed women in a small vulnerable island economy context. Given that the transition from being employed to unemployed and then the move to self-employment happened in a rather short span of time for these women, the contribution of this study is also to put at the forefront the industrial changes and the individual coping strategies.

Abstract

Purpose

The purpose of this paper is to identify and map trends in the Canadian apparel industry (in a global context) and, through the application of Porter's models, establish strategies that could be employed by Canadian small and medium enterprizes (SMEs) in response to the move toward trade liberalisation since the phasing out of the multi‐fibre arrangement.

Design/methodology/approach

The literature review established trends in the apparel industry both in Canada and globally. Qualitative research in the form of case studies highlighted apparel suppliers' perceptions of Canada's strengths and weaknesses as a business setting and provided preliminary information on possible supplier activities which provide value and competitive advantage. The analysis of the primary data also allowed the development of preliminary questions, answers to which will further enhance the understanding of clusters and their applicability to Canada's apparel SMEs.

Findings

Canada's apparel manufacturing industry is winding down while imports are continuing to grow. At the same time, the Canadian market is not large enough to sustain all the suppliers, thus forcing those who are competitive to export, primarily to the USA, which is Canada's major apparel export destination. The morphology of related and supporting industries to apparel suppliers is changing. The findings suggest that Canada's apparel supply is becoming more of a service and less of a manufacturing industry.

Originality/value

This paper provides an understanding of Canada's position in the global apparel map and ascertains whether competitive cluster strategies exist for the Canadian apparel industry. Furthermore, it sets the stage for further research by identifying knowledge gaps pertaining to the applicability of clusters to the apparel industry and providing data and findings to bridge these gaps.

Abstract

Purpose

The purpose of this paper is to provide new evidence about the technical efficiency and its determinants in Spanish textile sector during the period 2002-2009. The empirical results suggest that the effects of trade liberalization have led to higher levels of inefficiency in the Spanish sector, due to the lack of flexibility of firms to adjust to the environment, and perhaps to aggressive competition with fuzzy rules of the game. Controlling for specific factor like age, intensity of capital, salary by worker, regions and market share, the authors have obtained that the interaction between market share and size indicates that as firms have more size are also more inefficient.

Design/methodology/approach

In this paper, the stochastic frontier production function is considered, specifically, a panel data version of Battese and Coelli (1995), in which the technical inefficiency is estimated from the stochastic frontier and simultaneously explained by a set of variables. This approach avoids the inconsistency problems of the two-stage approach used in other empirical works when analyzing the inefficiency determinants.

Findings

This work provides new evidence about the technical efficiency and its determinants can be due to environmental or firm-specific factors in Spanish textile sector during the period 2002-2009. The authors have estimated the Cobb-Douglass stochastic production frontier following Battese and Coelli (1995) model to analyze an unbalanced panel.

Originality/value

The empirical results suggest that the trend of the inefficiency shows a curvilinear behavior in the form of U (turning point third-quarter of 2004). This result is related to the efficiency analysis through Kernel distributions (in static and dynamic form) confirmed a clear process of divergence. In the period 2002-2005 the efficiency of the firms analyzed maintained higher levels than the 2005-2009 period where there is deterioration. This may be related to the increased competition due to the end of the Multi-Fiber Arrangement in January 2005 and the entry of Chinese products in 2004.
