Abstract

Purpose

The purpose of this paper is to address the use of sludge from water treatment plant (WTP sludge), in its natural form (wet), in the construction industry, especially in the production of concrete, evaluating the effects of replacing natural sand with different WTP sludge levels in the concrete properties.

Design/methodology/approach

The dosage study evaluated mixtures with replacement levels of 0, 5, 7 and 10 percent of wet sludge in relation to the mass of natural sand, analyzing their effects on mechanical properties and water absorption in concrete with water/cement (w/c) ratios of 0.45, 0.55 and 0.65.

Findings

From the results obtained, it is possible to note that the addition of WTP sludge in its natural form (wet) reduces the strength of concrete. However, from a technical point of view, a level of replacement of up to 5 percent for applications in concrete is suitable, provided that it is not structural concrete.

Practical implications

Further studies should be conducted to verify the influence of the replacement of sand for heat-treated sludge in concrete properties, also analyzing the environmental viability linked to the calcination process.

Originality/value

Few studies are conclusive in relation to the use of WTP sludge in concrete production. This study shows statistically the negative effect of the addition of wet sludge in the mechanical properties and in the water absorption of concretes from different w/c ratios.

Abstract

Purpose

The distress that is associated with auditory hallucinations, or voices, is well documented. However, increasingly research into this phenomenon is also capturing those who cope with their voices, and live meaningful lives. Peer support is a popular and useful way in which to learn to manage the distress for voice-hearers. The Hearing Voices Network (HVN) acts as an umbrella organisation for which research, training and peer support groups exist (www.intervoiceonline.org). Despite the growing amount of peer support groups established, there is to date no published material on these groups. The purpose of this paper is to discuss these issue.

Design/methodology/approach

The present study used Interpretive Phenomenological Analysis to explore the experiences of four informants across three New South Wales HVN groups.

Findings

Results suggest that the social connections, value of sharing and desire for more group members are all important within the group. Beyond the group, informants described the increased willingness to talk to others about their voice experiences, improvements in sense of self and a positive change in their relationship with their voices.

Originality/value

The study demonstrates the importance of peer participation in the mental health workforce and the provision of safe spaces for those with lived experience to share and learn from each other in meaningful ways. Research implications include the need for further research measuring outcomes on a larger scale for these support groups.

Abstract

Purpose

It was aimed to propose and test a theoretical model to evaluate how some dimensions of environmental awareness influence the intention of consuming organic products using gender as a control variable.

Design/methodology/approach

The research was developed through quantitative methodology with the use of multivariate data analysis (PLS-SEM). The model uses a second-order construct. Although, it was conducted in a nonprobabilistic way using a convenience sample, with 213 university students.

Findings

It was confirmed the relation between the environmental awareness dimensions' influence and the intention to buy organic products that is also influenced according to the consumers' gender. There is a more positive effect and intensity in the organics' purchase by women.

Research limitations/implications

The nonprobabilistic nature in addition to the use of the convenience sample, factors that do not allow the generalization of the results, are some limitations. Moreover, the dimensions of environmental awareness proposed do not include all of the motivators about the organic consumption.

Practical implications

The results identified the factors that motivate the intention to consume organic products in Brazilian context and can contribute to managerial strategies formulation in order to increase the value perceived by the customer in relation to the consumption of these products.

Originality/value

This paper presents a deeper understanding about the dynamics between the factors that can guide the choice for organic products, besides providing a greater theoretical and empirical support tested by the use of a second-order construct.

Abstract

Purpose

Considering the different roles universities can perform to contribute to sustainable development, it is through teaching and outreach that they might be able to connect to the academic and local communities the most. The purpose of this study is to investigate the extent to which energy sustainability is being considered in campus teaching and outreach activities of different higher education institutions worldwide. In this context, this exploratory study was developed.

Design/methodology/approach

Through an online survey, a group of 36 universities from all continents was inquired about the level of sustainability in energy aspects of teaching and outreach activities, including curriculum change, training courses for staff and the regularity of outreach projects.

Findings

The results allowed global analysis concerning challenges and opportunities of these educational activities. This study also touches upon the interconnection between these practices and the contribution of universities towards the 2030 Agenda, and how universities can expand their activities and contribute practically to society. In terms of practical contributions, this study provides recommendations for higher education institutions to develop further in the area of energy sustainability through teaching and outreach.

Originality/value

Energy is a sustainability aspect relatively well covered by actions on campus operations, but there is a paucity of studies connecting this topic to teaching and outreach activities. This study is an approach to not only fill this gap but also reinforce the university role and contribution to the Sustainable Development Goals.
