Abstract

Purpose

The sheathing panels of traditional light wood frame shear walls mainly use oriented strand board (OSB) panels, and the damage of the traditional walls is mainly caused by the tear failure at the bottom corner of the OSB panel. In order to improve the lateral performance of the traditional light wood frame shear wall, a new type of end narrow panels reinforced light wood frame shear wall is proposed.

Design/methodology/approach

The monotonic loading tests and finite element analysis of nine groups of walls, with different types of end narrow panel, types of fasteners used on the end narrow panels and the end narrow panels edge fastener spacing, are carried out. The effects of different characters on lateral performance of light wood frame shear walls are reported and discussed.

Findings

The failure modes of the wall reinforced by parallel strand bamboo narrow panels with 150 mm edge nails spacing are similar to the traditional wall. Conversely, the failure modes of other groups of walls reinforced by end narrow panels are the tears of the bottom narrow panel or the bottom beam. The end narrow panel reinforced light wood frame shear wall can make full use of the material property of sheathing panels. Compared with the lateral performance of traditional walls, the new-type end narrow panels reinforced walls have better lateral performance.

Originality/value

A new type of end narrow panels reinforced light wood frame shear wall is proposed, which can enhance the lateral performance of the traditional light wood frame shear wall. The new-type walls have advantages of convenient operation, manufacture cost saving and important value of engineering application.

Abstract

Notes that many authors have supported the value of integrating qualitative and quantitative approaches within a research design to address research questions that aim both to develop or extend theory and test its application. Presents research which explores two alternative approaches to conducting qualitative interviews within an integrated research method. Aims to determine how those different approaches can enhance the design of the quantitative component of the research, and contribute to the interpretation of the quantitative data. Concludes that the findings indicate the importance of adopting both qualitative interview techniques within this combined approach, while completing a comprehensive review of the literature. Suggests that this will develop a theoretical framework and quantitative design, and assist in the interpretation of the quantitative data. The qualitative components of two outshopping studies, each study having a combined qualitative/quantitative research design, were selected to illustrate the nature of the data produced through each qualitative interviewing technique and the contribution of the data to the interpretation of the quantitative findings.

Abstract

Purpose

The purpose of this study is to explore the enviropreneurial marketing approach used by firms in China and its impact on the success of green marketing actions, with the aim of drawing useful lessons from the literature and successful green firms.

Design/methodology/approach

This study follows the inductive case study approach, and the qualitative data come from a study of four firms engaging in enviropreneurial marketing activities. Interview data were triangulated with qualitative data from other sources.

Findings

The evidence from this study indicates that enviropreneurial marketing plays a central role in developing innovative product or services, adopting an innovative and pragmatic green marketing mix that differentiates and creates changes within industry and markets.

Research limitations/implications

The main limitation of this study is that data samples are from successful firms labelled as “green” by the Chinese authorities, based on winning “official” awards. These do not necessarily represent the opinions of a cross section of firms within China with respect to enviropreneurial marketing. Future studies should include a mixed population of firms.

Practical implications

Policy makers and marketing practitioners need to consider drivers to ensure that Chinese firms integrate enviropreneurial marketing activities, which need to complement the delivery of functional value.

Social implications

Green initiatives/changes within the firm seem to be partly driven by the environmental orientation of these firms’ founders, thus, developing an environmental orientation in managers may be important to drive enviropreneurial marketing activities.

Originality/value

This study contributes by confirming the current literature on green marketing and examining the positive impact of enviropreneurial marketing on firms’ performance in the context of marketing in emerging markets.

Abstract

Purpose

Carbon nanotubes (CNTs) with exceptional mechanical, thermal and electrical properties are considered to be ideal for reinforcing high-performance structures. The interfacial stresses between the CNTs and surrounding matrix are important phenomena which critically govern the mechanical properties of CNTs-reinforced nanocomposites. A number of methods have been proposed to investigate the stress transfer across the CNT/matrix interface, such as experimental measurement and molecular dynamics (MDs). Experimental tests are difficulty and expensive. MDs simulations, on the other hand, are computationally inefficient. The purpose of this paper is to present a reasonably simplified model. Incorporating the simplified model, the analytical expressions of the interface stresses including the shear stress and longitudinal normal stress are obtained.

Design/methodology/approach

The analytical model consists of two concentric cylinders, namely a single-walled carbon nanotube (SWCNT) cylinder and a matrix cylinder, as the representative volume element (RVE). The interfacial stress analysis is performed using the shear lag model for the axisymmetric RVE. Analytical solutions for the normal stresses in the SWCNT and matrix, and the interfacial shear stress across the SWCNT/matrix interface are obtained. The proposed model has a great ability to theoretical prediction of the stress transfer between the matrix and CNTs.

Findings

In order to demonstrate the simulation capabilities of the proposed model, parametric studies are conducted to investigate the effects of the volume fraction of SWCNT and matrix modulus on the stress transfer. The axial stress in the matrix is decreasing with the increase of the volume fraction and decrease of the matrix modulus. As a result of more loads can be transferred to the SWCNT for a large volume fraction and small matrix modulus. These results show that using a large volume fraction and a small matrix modulus improves the efficiency of the stress transfer from the matrix to the CNTs.

Originality/value

A simple but accurate model using a simplified 2D RVE for characterizing the stress transfer in CNT-reinforced nanocomposites is presented. The predictions from the current method compare favourably with those by existing experimental, analytical and computational studies. The simple and explicit expressions of the interfacial stresses provide valuable analysis tools accessible to practical users.

Abstract

Purpose

Simulated child interviews, where adults play the role of a child witness for trainee investigative interviewers, are an essential tool used to train investigators to adhere to non‐leading, open‐ended questions. The aim of this study is to examine whether the use of a training procedure that guides persons playing the role of a child in simulated interviews results in interviewees producing more coherent narratives (measured by the number of story grammar details).

Design/methodology/approach

A total of 80 police officers individually engaged in ten‐minute interviews, whereby an untrained (colleague), or trained respondent, played the role of the child interviewee. For each child respondent condition, the interviews varied according to child age (five or eight years).

Findings

As predicted, trained respondents reported a higher proportion of story grammar elements and a lower proportion of contextual information than the untrained respondents, as well as more story grammar elements in response to open‐ended questions. However, there were limitations in how well both groups tailored their story grammar to the age of the child they were representing.

Originality/value

These findings demonstrate that our training procedure promotes a more coherent interviewee account, and facilitates a response style that is more reinforcing of open‐ended questions.

Abstract

Microfoundations of institutions are central to constructing place – the interplay of location, meaning, and material form. Since only a few institutional studies bring materiality to the fore to examine the processes of place-making, how material forms interact with people to institutionalize or de-institutionalize the meaning of place remains a black box. Through an inductive and historical study of Boston’s North End neighborhood, the authors show how material practices shaped place-making and institutionalized, or de-institutionalized, the meaning of the North End. When material practices symbolically encoded meanings of diverse audiences into the church, it created resonance and enabled the building’s meanings to withstand environmental change and become institutionalized as part of the North End’s meaning as a place. In contrast, when the material practices restricted meaning to a specific audience, it limited resonance when the environment changed, was more likely to be demolished and, thus, erased rather than institutionalized into the meaning of the North End as a place.

Abstract

Purpose

The purpose of this paper is to trace the history of official policy on the regulation of care homes in respect of end of life care and to contrast this with the results of research on this important theme, not least in terms of what is required to support care home staff in relation to dying residents and their relatives. A central concern is to argue for the open recognition that care homes now cater primarily for frail people towards the end of their lives. Good end of life care and a good death could become a positive “selling point”. The author concludes that the system of regulation has broadly failed to address a good death or good end of life care in a residential home. Death talk should no longer need to be avoided in care homes. The research suggests that appropriate support for care home staff in relation to dying residents needs careful identification and investment. A cultural shift is required.

Design/methodology/approach

Following a review of policy documents on regulation and standards of care in residential homes and a subsequent review of the research literature on death and dying in care homes, the paper illuminates the contrast between the ambitious aims in policy documents with very varied practice in everyday care of frail residents.

Findings

The recent systems of regulation have broadly failed to address a good death or good end of life care in residential homes. Open acknowledgement of death and dying should not be avoided in care homes. Appropriate support for care home staff in relation to dying residents needs careful identification and investment.

Originality/value

The focus of this paper is to contrast official policy with everyday practice. Whilst policy documents suggest recognition of the importance of dignity and respect from dying residents, the research literature indicates great variation in the practice of everyday care.

Abstract

Purpose

The initiative for sustainability in the construction industry has led to the innovative utilization of automobile tire waste, transforming it into value-added products, toward decarbonization in the construction industry, aligning with the development and sustainability goals of Al-Kharj Governorate. However, the disposal of these materials generates significant environmental concerns. As a payoff for these efforts, this study aims to contribute to a fruitful shift toward eco-friendly recycling techniques, particularly by studying the transformation of tire waste bead wires into recycled steel tire fibers (RSTFs) for sustainable concrete composites.

Design/methodology/approach

This research delves into how this technological transformation not only addresses environmental concerns but also propels sustainable tire innovation forward, presenting a promising solution for waste management and material efficiency in building materials. Recent studies have highlighted the superior tensile strength of RSTFs from discarded tires, making them suitable for various structural engineering applications. Recently, there has been a notable shift in research focus to the use of RSTFs as an alternative to traditional fibers in concrete. In this study, however, efforts have paid off in outlining a comprehensive assessment to investigate the viability and efficacy of repurposing tire bead wires into RSTFs for use in concrete composites, as reported in the literature.

Findings

This study examined the Saudi waste management, the geometrical properties of RSTFs, and their impact on the strength properties of concrete microstructure. It also examined the economic, cost, and environmental impacts of RSTFs on concrete composites, underscoring the need for the construction industry to adopt more sustainable and adaptable practices. Furthermore, the main findings of this study are proposed insights and a blueprint for the construction industry in Al-Kharj Governorate, calling for collective action from both public and private sectors, and the community to transform challenges into job opportunities for growth and sustainability.

Originality/value

This study pointed to thoroughly demonstrate the technological advancement in converting tire waste to reinforcing fibers by evaluating the effectiveness, environmental sustainability, and practicality of these fibers in eco-friendly concrete composites. Besides, the desired properties and standards for RSTFs to enhance the structural integrity of concrete composites are recommended, as is the need to establish protocols and further study into the long-term efficacy of RSTF-reinforced concrete composites.

Abstract

This chapter examines how proponents of industrialization used multiple modes of communication to socially construct the rational myth of industrialization in the French construction sector after World War II. We illuminate the respective roles of visual and verbal communication in this process. Our findings suggest that actors construct rational myths according to the following step-by-step method: first, they use visuals to suggest associations between new practices and valuable purposes; then they use verbal text to establish the technical rationality of certain practices; and lastly, they employ both verbal and visual communications to convey their mythical features.

Abstract

In an aircraft fuselage or motor gondola wherein all the stresses occurring are taken up by a spatial skeleton structure a, an outer covering is provided formed by individual reinforced panels b, c, d, e, each covered on one side with fabric, sheet‐metal or plywood f, g, h, i. All the panels may be removably secured to the structure a by means of clamps, screws, bolts, or the like, or some only of the panels at places where easy access to the interior of the fuselage is desired, the remainder of the fuselage being provided with a non‐removable covering. Each panel is reinforced by a lattice structure, or by profiled members, or by other means and may be mounted with its covered surface towards the interior of the fuselage. The panels may be interchangeable and some may be covered on both sides.
