Abstract

Purpose

This paper aims to propose a shape factor for granular materials based on particle shape. The scientific goal is to investigate the influence of particle shape on the mechanical properties of rockfill materials.

Design/methodology/approach

The method of generating four regular-shaped particles is based on the observation that most rockfill grains are regarded as like-triangle, like-rhombus, like-square and like-hexagon. A shape factor F that is developed using the Blaschke coefficient and a concave–convex degree is proposed. A biaxial compression test on rockfill materials under stress path is numerically simulated by discrete element method. The evolution of the shape factor F under the simulated stress paths is analyzed, and particle breakage rate, peak intensity and peak-related internal friction angle for rockfill materials are derived. A method of determining the shape factor F involved in the two functions is proposed.

Findings

A new micro-parameter is calibrated using the test data of one rockfill material. Particle shape greatly affects the particle breakage rate, peak intensity and peak-related internal friction angle for rockfill materials. The final experimental grading curves all approach the particle breakage grading curve proposed by Einav (the fractal dimension is 2.7).

Originality/value

This study proposes a shape factor F, which describes the geometric features of natural rockfill particles. The proposed shape factor F has a simple structure, and its parameters are easy to determine. The method provides an opportunity for a quantitative study on the particle shape of granular materials, and this study helps to better understand the influence of particle shape on the mechanical characteristics of rockfill materials.

Abstract

Purpose

The morphology of a building describes its outline and influences its architectural aesthetics and the cost directly. However, the literature on the impact of morphology on the aesthetics and cost of urban detached residential buildings is scarce. Thus, this study is significant because its aim was to identify the critical building morphology factors and the relationship that each of them maintains with the cost and aesthetics of urban detached residential buildings.

Design/methodology/approach

The multi-method qualitative approach was used to collect the required empirical data through interviews and case studies and to identify the effect of the morphology factors on the aesthetics and construction cost of urban residences in Sri Lanka, respectively. The collected data were analyzed using manual content analysis and descriptive statistics.

Findings

The study findings revealed that the morphology factors such as the roof and circulation spaces, open spaces and voids have a high impact on both the building cost and aesthetics. These findings will assist building designers in making effective design decisions on building costs and aesthetics so that a successful design outcome satisfying both the clients and design team could be obtained.

Originality/value

Although morphology has an impact on the cost and aesthetic of buildings, literature on the subject is scarce. Thus, this study is significant in that it aimed at identifying the significant building morphology factors in urban detached residential buildings and identifying their relationship with the cost and aesthetic of those buildings.

Abstract

Purpose

The purpose of this paper is to study online clothing consumers' behaviour and their visual attention mechanism to provide objective and quantitative evidences for the display and sales of online clothing.

Design/methodology/approach

Firstly, this paper conducted a Focus Group Methodology and questionnaire survey to obtain concern factors of online clothing. Secondly, the online clothing's bottom-up visual stimulation and consumer's top-down expectations were analysed, and proposed the hypotheses about significant stimulus of clothing and consumer's emotional experience. Thirdly, the online clothing consumer's visual attention rules and related qualitative results were discussed, and proposed visual attention law for online clothing. Finally, took the company's 84th quarter clothing design practices as research projects, all the hypotheses were demonstrated through eye movement physiology experiments, online clothing trial release and node sales data.

Findings

Online clothing has unique visual display ways compared with other online products such as online advertising, brands and food packaging. Clothing patterns of unfamiliar (fresh) font shapes are more attractive than the patterns of familiar fonts. The cause of the bottom-up visual attention bias is the contrast between clothing features, not the absolute stimulus intensity of the features themselves. Clothing factors can change their emotional experience from no difference to significant difference under the influence of other clothing factors.

Originality/value

Put forward hypotheses of online clothing consumer behaviour and its visual attention mechanism, provided objective and quantitative evidences through eye tracker.

Abstract

Purpose

While a substantial number of studies have examined information behaviour, most centred on choice of information source, student information behaviour, information behaviour of women, environmental uncertainty and scanning behaviour of top-level hotel executives. However, little is known about how the small and medium enterprise (SME) managers scan, seek, gather, document and use information relevant for emerging information and communication technology (EICT) adoption decision-making. This paper aims to examine the key success factors influencing SME manager’s information behaviour on EICT adoption decision-making.

Design/methodology/approach

This study deploys a qualitative approach to exploring 16 key success factors shaping SME managers’ information behaviour on EICT adoption decision-making. More specifically, the study adopted both unstructured and semi-structured interviews with 20 small business managers drawn purposeful from Crunch Database.

Findings

This study develops an extended technology, organisation and environment framework by incorporating the information context which helped to unravel 16 key success factors influencing small business managers’ information behaviour on EICT. From the technology context, uncertainty driven, compatibility, replacement of legacy technology, relative advantages, lack of technical know-how and perceived affordability fit for purpose influence SME managers’ information behaviour. Users’ acceptance information, efficiency driven, owner’s support shape the organisation context of perceived information need; competitor’s intelligence gathering, customer’s information gathering provider credibility and government policy influence the environmental context of perceived information need; and finally, perceived information sources credibility, herding event, testimonial and openness to other people’s ideas and experiences are shaped by the information context.

Research limitations/implications

Qualitative research is normally subjective, interpretive and limited on the sample used. Because of the limited number of interviews, the generalisation of the framework and the finding is difficult. Therefore, the finding and the framework need to be established across broader population. The findings are vital considering the fact that small business managers are limited in knowledge and the study may improve the way and manner they go about seeking and gathering information relevant in adopting new ICT.

Originality/value

This research provides further insight into SME managers’ information behaviour by developing a framework and identifying main factors influencing SMEs information behaviours on EICT. Therefore, understanding such factors will enrich their knowledge on some of the factors that may shape their decisions during EICT adoption decision to make effective decision.

Abstract

Purpose

The purpose of this study is to investigate the various enablers of and constraints on employees' information sharing on an enterprise social media platform. It draws on two theoretical perspectives, communication privacy management theory and the technology affordance framework, as well as on empirical data in an attempt to paint a comprehensive picture of the factors shaping employees' decisions to share or not share information on enterprise social media.

Design/methodology/approach

This qualitative field study is based on semi-structured interviews and enterprise social media review data from a large Nordic media organization.

Findings

On an enterprise social media platform, privacy management principles shape employees' information-sharing decisions in relation to personal privacy boundaries, professional boundaries and assumed risks, online safety concerns and perceived audience. Additionally, the technological affordances of visibility, awareness, persistence and searchability shape employees' information sharing in varying and sometimes even contradictory ways. Finally, organizational factors, such as norms, tasks and media repertoires, are associated with employees' information-sharing decisions. Together, these three dimensions, personal, technological and organizational, form a model of the enablers of and constraints on employees' decisions to share information on enterprise social media.

Originality/value

This study extends the understanding of different factors shaping employees' decisions to share or not share information on enterprise social media. It extends the two applied theories by uniquely combining interpersonal privacy management principles with a technological affordance framework that focuses on the relationship between the user and the technology. This research also furthers the authors' knowledge of what privacy management principles mean in the organizational context. This study shows connections between the two theories and extends the understanding of technology affordances as not only action possibilities but also constraining factors. Additionally, by revealing what kinds of factors encourage and inhibit information sharing on enterprise social media, the results of this study support organizations in their efforts to manage information sharing on enterprise social media systems.

Abstract

Several comprehensive reviews are united in drawing the conclusion that the cumulative research evidence on work team diversity is equivocal. Rather than review the extant state of diversity research, in this paper we redirect attention to the context of workplace diversity as a possible explanation for these mixed findings. We discuss how diversity context may be conceptualized, specify various aspects of this context at multiple levels of analysis, and consider how contextual variables can shape the outcomes of work team diversity. We present findings from a literature review (1999–2006) to identify key trends and patterns of results reported in recent research as well as contextual factors that have received attention to date. This paper also considers how the non-significant, positive, negative, and curvilinear effects of diversity reported in studies can be explained by the contextual factors outlined. Implications for future research are also discussed.

Abstract

Purpose

In order to develop high shape retention yarn and investigate the effects of spinning process and core yarn contents on the shape retention of yarn, in this paper, three kinds of yarns, JC/T400 18.5tex (55.6dtex) core-spun yarn, JC/T400 18.5tex (44.4dtex) core-spun yarn and JC18.5tex pure cotton yarn were spun by using the complete condensing Siro-spinning technology. The paper aims to discuss these issues.

Design/methodology/approach

In this paper, the core-spun yarns were spun by using the complete condensing spinning and Siro-spinning technology. Two key spinning processes, yarn twist factor and core yarn pre-draft ratio, were optimized by using the orthogonal test method first. Then, via the variable control method, the position of the core yarn, the position of the bell mouth and the center distance between two bell mouths were optimized, respectively, and corresponding optimal spinning process of the three yarns was determined. Finally, the yarns were spun under the optimal process, and the performance of the spun yarns was tested and compared.

Findings

Results show that the yarn twist factor affects yarn strength and hairiness, the position of bell mouth affects the evenness and hairiness of the yarn mainly, and the position of the core yarn affects the coverage and hairiness of the yarn. For the Z-twist spinning, the core yarn enters the front roller from the left side of two strands center, which is beneficial to improve the covering effect of core yarn, and reduce the pilling phenomenon of the yarn. The contents of core yarn affect indicators of the yarn shape retention, such as yarn strength, elastic recovery and abrasion resistance.

Originality/value

The shape retention of yarns affects the shape retention of fabrics, and the production of yarn with high shape retention is a key step in achieving shape retention of fabrics. At present, there are little studies on the shape retention of yarns, most researchers shave focused on shape retention of fabrics. Using the complete condensing Siro-spinning method to spin the core-spun yarn can improve the quality of the yarn. Compared with traditional ring-spinning yarns, the addition of the core yarn can improve the shape retention of the yarn.

Abstract

Purpose

The purpose of this paper is to illuminate how supplier evaluation practices are linked to supplier performance improvements. Specifically, the paper investigates how performance information travelling between the evaluating buyer and the evaluated suppliers is shaped and reshaped in the evaluation process.

Design/methodology/approach

The paper relies on a multiple, longitudinal case research methodology. The two cases show two companies' efforts in designing, implementing, and using supplier evaluation in order to improve supplier performance.

Findings

The findings show how the dynamics of representing, reducing, amplifying, dampening, and directing shape and reshape supplier evaluation information. In both companies, evaluation practices were defined, redefined, and re‐directed by the involved actors' perception and decision making, as well as organisational structures, IT systems, and available data sources.

Research limitations/implications

The identified factors and dynamics could be empirically tested on larger samples to increase generalisability.

Practical implications

The results provide insights into how an evaluating buyer may analyse and control supplier evaluation processes thereby improving their effects. Managers must know how performance information is altered before reaching key supplier actors in order to optimise supplier performance.

Originality/value

Current studies on supplier evaluation practices are limited in their focus on design, implementation, or use. This paper explores all three phases empirically, and proposes a set of dynamics to better understand and control the often taken for granted link between intentions and outcome of such practices. In relation to future research, the authors propose a more holistic direction, which will take the entire supplier evaluation process as its unit of analysis.

Abstract

Purpose

Various theoretical studies were carried out which attempted to identify impacting factors of cultural changes; however, these studies ignored the correlation among other affecting factors all together. In this paper, the authors aim not only to discuss the hidden layers that trigger the cultural changes but also to answer the questions of how to identify the main factors in each layer based on casual layered analysis (CLA), which could have a strong impact in shaping other layers’ factors? What are the dominant metaphors and worldviews that human beings are telling themselves about our universe that influences the future cultural changes?

Design/methodology/approach

To answer the questions of “how to identify the main factors in each layer,” the CLA methodology was used to investigate the underlying reasons. CLA takes into account four layers (litany, social systems, dominant discourse and worldviews and metaphors), which could be a tremendous help in identifying the mentioned factors.

Findings

The analysis shows that there are some contributing factors such as economy, technology, politics, society, environment, mass media, globalization and migration at the second layer – “social systems layer” – which may trigger cultural changes in first layer “litany”; in addition, in the third and deeper layer two dominant worldviews – materialist/secular and religious affecting the contributing factors in the second layer – were identified. Such worldviews are, in turn, supported by metaphors or perfect stories/myths of the deepest layer.

Originality/value

It can be concluded that because the cultural changes as a reality is composed of different layers, it is important to dig into different layers of reality to comprehend the significant shaping factors of that reality to visualize and make the better future.

Abstract

Order picking, the assembly of a customer’s order from items in storage, is an essential link in the supply chain and is the major cost component of warehousing. The critical issue is to simultaneously reduce the cost and increase the speed of the order picking activity. The main objectives are to: evaluate various routeing policies in a random storage environment; evaluate the impact of warehouse shape and pick‐up/drop‐off location; and examine the interaction of the routeing policies, warehouse shape, and pick‐up/drop‐off location under different pick list sizes. The experimental results clearly indicate that the optimal routeing procedure generates significantly shorter routes than heuristic methods. The composite and largest gap routeing policies are, however, significantly better than simpler heuristic procedures. Further testing, in addition, indicates that the shape of the warehouse and the location of the pick‐up/drop‐off point can affect the picking efficiency.
