This paper aims to discuss the evaluation of the compressive and splitting tensile strength of concrete mixes containing different proportions of up to 20 per cent glass aggregate. Portions of sand in concretes with and without admixtures were replaced with measurements of glass aggregates.

“Glascrete” is a term used for concrete in which crushed glass is used as a substitute for all or part of the aggregates. Glass can be recycled many times without changing its properties, making it an ideal material in concrete. Overall, 144 cubes and 144 cylinders of glascretes were prepared with different admixtures and subjected to compressive and splitting tensile strength test.

A comparison with a 21-day control mix indicated that glass aggregates are replacing sand in concrete ranging from 5 to 20 per cent by volume, resulting in 3.8-10.6 per cent and 3.9-16.4 per cent fall in compressive and tensile strength, respectively. However, the use of mineral admixture improved the properties of the mixes at 3, 7, 14 and 21 days.

Cities worldwide are congested, and even those with the best waste-management system would have issues with waste disposal after the year 2030. Consequently, waste management is a current issue for cities all over the world.

This study aims to evaluate the physical properties of mortar mixes that contain different volumes of waste glass as substitutes for fine aggregate with or without additives. Mineral additives are used to improve the mechanical properties of glascrete mixes in addition to its chemical resistance by absorbing the OH⁻ ions responsible for the possible alkali-silica reaction (ASR). It also reduces the adverse effects of mix-dimensional stability. Water-reducing admixtures are used to reduce the impact of the ASR by minimizing the amount of moisture in concrete, in effect decreasing the possible expansion of any produced gel. In this research, compressive and splitting tensile strength of concrete mortar containing waste glass of limited substitutions is evaluated.

The purpose of this paper is to investigate how consumers’ affective goal pursuit influences the relationship between their affect and satisfaction in services. In particular, it examines when affect can directly influence satisfaction and when such an impact is mediated by perceived service quality.

This research explores consumers’ consumption goals in three different service contexts, i.e., a primarily pleasure-seeking hedonic service context, a primarily arousal-seeking hedonic service context and a utilitarian (non-affect-seeking) service context.

Results from two studies show that the primary affective consumption goal determines which specific affect can directly influence satisfaction. Other desirable non-primary affect influences satisfaction through the mediation of perceived service quality.

This research focuses on the service contexts in which consumers’ primary consumption goals vary. Further research may focus on the priority and strength of a consumer’s various consumption goals in different services and study how the priority and strength of different consumption goals determine how affect influences quality and satisfaction.

The study provides several insights for service providers and retailers to recognize that consumers’ primary consumption goals may vary in different service contexts, for different consumers, and even at different usage situations. Accordingly, marketers need to develop different strategies for consumer with different goal pursuit in services.

While the literature has documented that consumer affect influences consumer satisfaction in general, it is unclear how different consumption goals influence the impact of affect on satisfaction. This research contributes to the consumer goal literature by demonstrating the importance of primary consumption goals in the post-consumption evaluation of services.

Concrete is a building material widely used for the infrastructural development. Cement is the binding material used for the development of concrete. It is the primary cause of CO₂ emission globally. The purpose of this study is to develop sustainable concrete material to satisfy the present need of construction sector. Geopolymer concrete (GPC) is a sustainable concrete developed without the use of cement. Therefore, investigations are being conducted to replace the cement by 100% with high calcium fly ash (FA) as binding material.

High calcium FA is used as cementitious binder, sodium hydroxide (NaOH) and sodium silicates (Na₂SiO₃) are used as alkaline liquids for developing the GPC. Mix proportions with different NaOH molarities of 4, 6, 8 and 10 M are considered to attain the appropriate mix. The method of curing adopted is ambient and oven curing. Workability, compressive strength and microstructure characteristics of GPC are analysed and presented.

An increase of NaOH in the mix decreases the workability. Compressive strength of 29 MPa is obtained for Mix-I with 8 M under ambient curing. A polynomial relationship is obtained to predict the compressive strength of GPC. Scanning electron microscope analysis is used to confirm the geo-polymerisation process in the microstructure of concrete.

This research work focuses on finding some alternative cementitious material for concrete that can replace ordinary portland cement (OPC) to overcome the CO₂ emission owing to the utilisation of cement in the construction industry. An attempt has been made to use the waste material (high calcium FA) from thermal power plant for the production of GPC. GPC concrete is the novel building material and alternative to conventional concrete. It is the ecofriendly product contributing towards the improvement of the circular economy in the construction industry. There are several factors that affect the property of GPC such as type of binder material, molarity of activator solution and curing condition. The novelty of this work lies in the approach of using locally available high calcium FA along with manufactured sand for the development of GPC. As this approach is rarely investigated, to prove the attainment of compressive strength of GPC with high calcium FA, an attempt has been made during the present investigation. Other influencing parameter which affects the strength gain has also been analysed in this paper.

This paper aims to provoke a conversation in marketing scholarship about the overlooked political nature of doing research, particularly for those who research issues of social (in)justice. It suggests a paradigmatic shift in how researchers might view and operationalise social justice work in marketing. Emancipatory praxis framework offers scholars an alternative way to think about the methodology, design and politics of researching issues of social relevance.

This is a conceptual paper drawing on critical theory to argue for a new methodological shift towards emancipatory praxis.

As social justice research involves a dialectical relationship between crises and critique, the concept of emancipation acts as a methodological catalyst for furthering debate about social (in)justice in marketing. This paper identifies a set of methodological troubles and challenges that may disrupt the boundaries of knowledge-making. A set of methodological responses to these issues illustrating how emancipatory research facilitates social action is outlined.

Emancipatory praxis offers marketing scholars an alternative methodological direction in the hope that more impactful and useful ways of knowing can emerge.

The paper is intended to change the ways that researchers work in practical and concrete terms on issues of social (in)justice.

Although this paper is theoretical, it argues for an alternative methodological approach to research that reorients researchers towards a politicised praxis with emancipatory relevancy.

Emancipatory praxis offers a new openly politicised methodological alternative for addressing problems of social relevance in marketing. As a continuous political and emancipatory task for researchers, social justice research involves empirical encounters with politics, advocacy and democratic participation, where equality is the methodological starting point for research design and decisions as much as it is the end goal.

This study aims at designing consistent and durable concrete by making use of waste materials. An investigation has been carried out to evaluate the performance of conventional and optimal concrete (including 5% GP) at high temperatures for different exposure times.

An experimental work is carried out to compare the conventional and optimal concrete with respect to weight loss, mechanical strength characteristics (compressive, tensile and flexural) after exposed to 100, 200 and 300 °C with 1, 2 and 3 h duration of exposure followed by cooling in furnace for 24 h and then air cooling.

The workability of granite powder modified concrete decreases as percentage of replacement increases. Compressive, tensile and flexural strengths all increased at 100 °C when compared to strength characteristics at normal temperature, regardless of the exposure conditions, and there was no weight loss noticed. For 200 and 300 °C, the strengths were decreased compared to normal temperature and an elevated temperature of 100 °C, as weight loss of concrete specimens are observed to be decreased at these temperatures. So, the optimum elevated temperature can be concluded as 100 °C.

Incorporating pozzolanic binder (granite powder) as cement replacement subjecting to elevated temperatures in an electric furnace is the research gap in this area. Many of the works were carried out replacing GP for fine aggregate at normal temperatures and not at elevated temperatures.

The purpose of this paper is to examine the effects of other customer perception (OCP) (Brocato et al., 2012) on focal customer’s service quality perception and revisit intention in high- and low-involvement services and the effect of customer’s need for uniqueness (NFU) as a boundary condition of the above relationships.

Following a theoretical methodology, hypotheses were developed to analyze the effect of OCP, service involvement and customer’s NFU. A 2 × 2 × 2 scenario-based experiment was designed. Multivariate analysis of variance (MANOVA) was used to test the hypotheses.

The analysis reveals that the presence of conforming (versus non-conforming) other customers improves service quality perception and revisit intention of focal customers in high-involvement services, but not in low-involvement services. However, the relationship between similarity perception and outcome variables does not hold good for high-NFU customers.

This study suggests that conforming and non-conforming other customers are critical in forming service quality perception of high-involvement services, and highlights the boundary condition of this relationship. If service managers take service involvement and individual differences into account, and strategize their service offering aligned to their target customers, influence of other customers can be managed more efficiently.

As this study is one of the first empirical studies to focus on the effect of OCP on service quality perception and examine its boundary condition, it contributes significantly to the body of knowledge. Future research directions are discussed and managerial implications are proposed.

Despite the over-representation of stepfamilies in the clientele receiving protective services, there is still very little information about the different forms of the parental commitment of stepfathers in those families. However, the characteristics of families receiving child protective services (CPS) are likely to influence the way that the stepfathers’ commitment is expressed.

Taking into account the viewpoint of mothers (n = 10), stepfathers (n = 10), and adolescents (n = 10), this study attempted to document, using the free association method and semistructured interviews, the following: (1) the representations that the members of these stepfamilies had of the stepfathers’ parental commitment; and (2) the way in which engagement was expressed in daily life.

While the participants agreed that the stepfather had a parental role to play, that is to take care of the children, they did not necessarily agree about which dimensions were the most important. Whereas the adults emphasized the child-rearing dimension of this role and the necessary cooperation with the biological parents, the adolescents insisted on the relational aspect. The results likewise indicated that these men were very committed to their partners’ adolescents and showed that even in families challenged by problems that lead to involvement with CPS, stepfathers can play a positive, supportive role.

This study represents an important addition to the existing literature on the role of stepfathers in that it uses multiple measures and direct reports from father figures allowing us to explore the main dimensions of stepfather commitment.
