Abstract
Purpose
The purpose of this paper is to implement the combined approach of Decision Making Trial and Evaluation Laboratory (DEMATEL) and system dynamic (SD) for examining the impacts of several elements on the implementation of green supply chain management (GSCM) practices in the furniture industry concerning the amount of wood waste resulted and the demand of wood materials.
Design/methodology/approach
The paper develops an SD-based model by using four approaches, i.e., “demand of furniture”, “raw material”, “revenue of furniture industry” and “the implementation of green supply chain management (GSCM) practices”.
Findings
The simulation results have shown that the best conditions occur in the fourth scenario or a combined scenario. This scenario can guarantee a decrease in need of wood and discarded wood waste due to the use of wood waste for raw material by some industries. This scenario can thus increase the share of wood waste used as raw materials.
Research limitations/implications
The first limitation of this study is on the calculation of the amount of wood, which has used the data of wood products obtained from the Central Java Provincial Agency of the Environment and Forestry. This calculation has not taken into account the forest area degradation. Second, the demand for furniture has been converted from the historical data of domestic and foreign sales. Third, the model used in this study has not considered the decrease of the production cost and the increase of the profit gained by the wooden furniture small- and medium-sized enterprises that use the wood waste as part of their raw material.
Practical implications
This research provides essential insights into the context of implementing the policies to increase the implementation of GSCM practices.
Originality/value
This research can make a difference in two aspects. First, it has tested policies, not in isolation. It has simultaneously tested various combinations of policies because the furniture industry can be seen as a system with complex relationships among the elements. Second, this study can broaden scientific insights related to the use of the DEMATEL method in the SD methodology.

Abstract
Purpose
The purpose of this paper is to determine the effect of Imersol Aqua impregnation of Scotch pine, Oriental spruce, and Uludağ fir on the surface adhesion strength of various types of varnishes. The finding obtained would benefit the manufacturers of building materials and furniture, where the surface adhesion strength of water‐based varnishes is a concern.
Design/methodology/approach
For this purpose, test samples were prepared from Scotch pine, Oriental spruce, and Uludağ fir woods that met the requirements of ASTM D 358. The samples were impregnated with Imersol Aqua using short‐, medium‐, and long‐term immersion techniques according to ASTM D 1413 and the manufacturer's instructions. After impregnation, surfaces were coated with synthetic, acrylic, polyurethane, and water‐based varnishes in accordance with ASTM D 3023 standards. After the varnishing process, the adhesion strength of the samples was determined in accordance with ASTM D 4541.
Findings
It was also found that among the wood samples, the adhesion strength was highest in Scotch pine and lowest in Uludağ fir. The synthetic varnish produced the highest adhesion strength, whereas polyurethane and acrylic varnishes had the lowest adhesion strength. The adhesion strength was highest after medium‐term immersion and lowest after long‐term dipping. The highest adhesion strength (4.299 MPa) was produced by a combination of Scotch pine, medium‐duration immersion, and the use of a wood‐based varnish. The lowest adhesion strength (2.090 MPa) resulted from the combination of Uludağ fir, long‐term immersion, and a water‐based varnish.
Research limitations/implications
Impregnating woods using materials with appropriate water repellent, biotic, and abiotic effects before the application of varnishes and paints is important for long‐term protection against photochemical degradation, dimensional changes, biological factors, and fire.
Practical implications
The effect of a varnish on surface adhesion strength can determine the usefulness of the varnish.
Originality/value
Improving surface adhesion of some varnishes via medium‐term impregnation with Imersol Aqua impregnation should be used on Scotch pine, Oriental spruce, and Uludağ fir woods which could be used in the manufacturing of building materials and furniture, where the surface adhesion strength of water‐based varnishes is a concern.

Abstract
Purpose
The purpose of this paper is to determine the impacts of impregnation with Imersol Aqua to red colour tone (RCT) of some softwood materials and varnishes.
Design/methodology/approach
For this purpose, test samples prepared from Scots pine (Pinus sylvestris Lipsky), Oriental spruce (Picea orientalis Link) and Uludağ fir (Abies Bornmülleriana Mattf.), which met the requirements of ASTM D 358, were impregnated with Imersol Aqua by short‐term, medium‐term and long‐term immersion techniques in accordance with ASTM D 1413 and producer's definition. After impregnation, surfaces were coated by synthetic, acrylic, water‐based and polyurathane varnishes in accordance with ASTM D 3023 standards. RCT values of samples after varnishing process were determined in accordance with ASTM D 2244.
Findings
It was found that RCT was the highest in Scots pine, long‐term dipping and synthetic varnish, and the lowest in Uludağ fir, short‐term dipping and water‐borne varnish. Considering the interaction of wood type, period of impregnation and type of varnish, RCT was the highest in pine, short term of dipping and acrylic varnish and the lowest in Oriental spruce, short term of dipping and synthetic varnish. So, impregnation process, impregnation period and varnishes applied during tests showed increasing impact for RCT value of Scots pine, Oriental spruce and Uludağ fir woods. This result must be taken into care in manufacture of wooden furniture and construction elements where RCT is important.
Research limitations/implications
The endurance of the protective coating (such as varnish) to external effects is limited and the lifetime of the coating is determined by the type and the severity of the effects to which it is exposed.
Practical implications
The impact of varnish type, wood material type and impregnation chemical on RCT can determine the usefulness of the massive wood materials where RCT values are important.
Originality/value
It is conjectured that especially for the manufacturers and consumers in the furniture, construction and decoration sector, the data obtained in this study will contribute to the making up of the deficiencies in the understanding of the subject.

Abstract
High-involvement work processes (HIWPs) are associated with high levels of employee influence over the work process, such as high levels of control over how to handle individual job tasks or a high level of involvement at team or workplace level in designing work procedures. When implementations of HIWPs are accompanied by companion investments in human capital – for example, in better information and training, higher pay and stronger employee voice – it is appropriate to talk not only of HIWPs but of “high-involvement work systems” (HIWSs). This chapter reviews the theory and practice of HIWPs and HIWSs. Across a range of academic perspectives and societies, it has regularly been argued that steps to enhance employee involvement in decision-making create better opportunities to perform, better utilization of skill and human potential, and better employee motivation, leading, in turn, to various improvements in organizational and employee outcomes.
However, there are also costs to increased employee involvement and the authors review the important economic and sociopolitical contingencies that help to explain the incidence or distribution of HIWPs and HIWSs. The authors also review the research on the outcomes of higher employee involvement for firms and workers, discuss the quality of the research methods used, and consider the tensions with which the model is associated. This chapter concludes with an outline of the research agenda, envisaging an ongoing role for both quantitative and qualitative studies. Without ignoring the difficulties involved, the authors argue, from the societal perspective, that the high-involvement pathway should be considered one of the most important vectors available to improve the quality of work and employee well-being.

Abstract
Purpose
Over the last eight years, the Middle East has experienced a series of high profile conflicts which have resulted in over 5.6 million Syrians forced to migrate to neighbouring countries within the MENA (Middle East and North Africa) region or to Europe. That have exerted huge pressure on hosting countries trying to accommodate refugees in decent shelters and in quick manner. Temporary shelters normally carry a high environmental burden due to their short lifespan, and the majority are fabricated from industrialised materials. This study assesses the carbon impact for a minus carbon experimental refugee house in Sweden using life cycle assessment (LCA) as tool. SimaPro and GaBi software were used for the calculations and the ReCiPe midpoint method for impact assessment. The results show that using local plant-based materials such as straw, reeds and wood, together with clay dug from close to the construction site, can drastically reduce the carbon footprint of temporary shelters and even attain a negative carbon impact of 226.2 kg CO2 eq/m2. Based on the results of the uncertainty importance analysis, the overall global warming potential impact without and with sequestration potential are mostly sensitive to the variability of the GWP impact of wood fibre insulation.
Design/methodology/approach
The methodology is designed to calculate the GWP impact of the refugee house over its entire life cycle (production, operation and maintenance and end of life). Then, the sensitivity analysis was performed to explore the impact of input uncertainties (selection of material from the database and the method) on the total GWP impact of the refugee house with and without sequestration. The ISO standards (International Standard 14040 2006; International Standard 14044 2006) divide the LCA framework into four steps of Goal and scope, inventory analysis, impact assessment, and interpretation.
Findings
This study has shown an example for proof of concept for a low impact refugee house prototype using straw, reeds, clay, lime and wood as the principle raw materials for building construction. Using natural materials, especially plant-based fibres, as the main construction materials, proved to achieve a minus carbon outcome over the life cycle of the building. The GWP of the shelter house without and with sequestration are found to be 254.7 kg CO2 eq/m2 and -226.2 kg CO2 eq/m2, respectively.
Originality/value
As there are still very few studies concerned with the environmental impact of temporary refugee housing, this study contributes to the pool of knowledge by introducing a complete LCA calculation for a physical house prototype as a proof of concept on how using low impact raw materials for construction combined with passive solutions for heating and cooling can reach a minus carbon outcome. The GWP of the shelter house without and with sequestration are found to be 254.7 kg CO2 eq/m2 and -226.2 kg CO2 eq/m2.

Abstract
This chapter provides an introduction to the problematic notion of teaching excellence in higher education, which is a focus of this collection. It draws on an extensive review of relevant literature to explore how teaching excellence is defined and conceptualised and what factors underpin different conceptions. It notes that definitions are disparate, often context-specific and are influenced by a range of different ‘players’. It then examines how different conceptualisations play out at the macro, meso and micro levels and highlights the tensions between performative and transformative notions of teaching excellence. It notes the move from ‘surface’ to ‘deep’ excellence and efforts to articulate a more holistic conception of teaching excellence that emphasises the relational, emotional and moral dimensions of teaching. It suggests that, rather than seeking singular definitions and conceptions, it may be more useful to talk of ‘teaching excellences’, to reflect a stratified and plural sector, a diverse student body and different disciplinary families. Equally, it argues for further investigation of the intersections of teaching excellence with other key drivers of institutional change, such as student engagement and well-being, inclusion and diversity, widening participation and retention and success.
