Abstract

Purpose

This paper aims to numerically study the compositional flow of two- and three-phase fluids in one-dimensional porous media and to make a comparison between several upwind and central numerical schemes.

Design/methodology/approach

Implicit pressure explicit composition (IMPEC) procedure is used for discretization of governing equations. The pressure equation is solved implicitly, whereas the mass conservation equations are solved explicitly using different upwind (UPW) and central (CEN) numerical schemes. These include classical upwind (UPW-CLS), flux-based decomposition upwind (UPW-FLX), variable-based decomposition upwind (UPW-VAR), Roe’s upwind (UPW-ROE), local Lax–Friedrichs (CEN-LLF), dominant wave (CEN-DW), Harten–Lax–van Leer (HLL) and newly proposed modified dominant wave (CEN-MDW) schemes. To achieve higher resolution, high-order data generated by either monotone upstream-centered schemes for conservation laws (MUSCL) or weighted essentially non-oscillatory (WENO) reconstructions are used.

Findings

It was found that the new CEN-MDW scheme can accurately solve multiphase compositional flow equations. This scheme uses most of the information in flux function while it has a moderate computational cost as a consequence of using simple algebraic formula for the wave speed approximation. Moreover, numerically calculated wave structure is shown to be used as a tool for a priori estimation of problematic regions, i.e. degenerate, umbilic and elliptic points, which require applying correction procedures to produce physically acceptable (entropy) solutions.

Research limitations/implications

This paper is concerned with one-dimensional study of compositional two- and three-phase flows in porous media. Temperature is assumed constant and the physical model accounts for miscibility and compressibility of fluids, whereas gravity and capillary effects are neglected.

Practical implications

The proposed numerical scheme can be efficiently used for solving two- and three-phase compositional flows in porous media with a low computational cost which is especially useful when the number of chemical species increases.

Originality/value

A new central scheme is proposed that leads to improved accuracy and computational efficiency. Moreover, to the best of authors knowledge, this is the first time that the wave structure of compositional model is investigated numerically to determine the problematic situations during numerical solution and adopt appropriate correction techniques.

Abstract

Purpose

The purpose of this paper is to propose a model of competitiveness for small and medium-sized enterprises (SMEs) by investigating the structural relationship between organizational structure, knowledge quality (KQ) dimensions, improvisational creativity, compositional creativity and innovation in an emerging market – Malaysia – grounding in sense-making and organizational improvisational theories.

Design/methodology/approach

A total of 358 valid questionnaires administered among SMEs’ top management were used in examining the measurement model and structural relationship between latent constructs using partial least squares (PLS) path-modelling approach.

Findings

The findings indicate that a flat organizational structure influences business entities’ sense-making activities in the way they realize the intrinsic value of knowledge (intrinsic KQ) and take action to apply the organizational knowledge (actionable KQ). These sense-making activities are also conducive to SMEs’ improvisational creativity, compositional creativity and innovative capabilities. All KQ dimensions are positively interrelated, thus supporting sense-making theory.

Originality/value

A sustainable competitive advantage for SMEs requires a setting that is based on a lean, decentralized and cooperative organizational structure that shapes organizational KQ. As a contribution to the literature, accessibility KQ is introduced as a KQ dimension. Even though previous research was unclear on the reflectiveness/formativeness of KQ, by applying confirmatory tetrad analysis-PLS, this study empirically supports that KQ is a formative construct.

Abstract

Purpose

The purpose of this paper is to demonstrate an actual compositional process that entails a diversity of music information modes and describe the way these modes contribute to the creative aspirations of a composer.

Design/methodology/approach

The music information typology proposed by Rousi, Savolainen and Vakkari is used as a point of departure for defining the different modes of music-related information. First, relevant music information modes are identified from the composer-informant’s verbal description of a compositional process. Then, their proportions and dynamics are examined.

Findings

The findings suggest that the music information typology may be applied within the context of musical composition, that is, all of its five modes of music information could be identified from the composer’s verbal description of the compositional process. However, two additional significant information modes were identified: shaping music as the third mode of enactive representations and genuine iconic representations.

Research limitations/implications

The purpose of this case study is not to claim that the results regarding the significance of individual music information modes apply to all compositional processes within diverse genres of music.

Originality/value

This study introduces a new mode of music information indicative of the artistic capacity of expressiveness: shaping musical structures as the third mode of enactive representations was the means whereby the composer made musical structures work for himself and hence created performative power in his music.

Abstract

Purpose

Team cognition is known to be an important predictor of team process and performance. DeChurch and Mesmer-Magnus (2010) reported the results of an extensive meta-analytic examination into the role of team cognition in team process and performance, and documented the unique contribution of team cognition to these outcomes while controlling for the motivational dynamics of the team. Research on team cognition has exploded since the publication of DeChurch and Mesmer-Magnus’ meta-analysis, which raises the question: to what extent do the effect sizes reported in their 2010 meta-analysis still hold with the inclusion of newly published research? The paper aims to discuss this issue.

Design/methodology/approach

The authors updated DeChurch and Mesmer-Magnus’ meta-analytic database with newly published studies, nearly doubling its size, and reran their original analyses examining the role of team cognition in team process and performance.

Findings

Overall, results show consistent effects for team cognition in team process and performance. However, whereas originally compilational cognition was more strongly related to both team process and team performance than was compositional cognition, in the updated database, compilational cognition is more strongly related to team process and compositional cognition is more strongly related to team performance.

Originality/value

Meta-analyses are only as generalizable as the databases they are comprised of. Periodic updates are necessary to incorporate newly published studies and confirm that prior findings still hold. This study confirms that the findings of DeChurch and Mesmer-Magnus’ (2010) team cognition meta-analysis continue to generalize to today’s teams.

Abstract

Purpose

This paper aims to understand how social, cultural and political economic dynamics inform packaging design. Specifically, it focuses on one of the oldest Turkish pasta brands, Piyale, and seeks to understand the impact of the changes in the macro-institutional structures on its packaging practices over the course of almost a century.

Design/methodology/approach

The analysis is mainly based on data collected through archival and documentary research. The archival data are gathered from various sources including the personal archives of the former managers, advertisements published in the popular magazines of the time and industry reports and documents. Data are analyzed using a combination of compositional and social semiotic analysis.

Findings

The analysis indicates four distinct periods in the brand’s history. The design elements and visual identity reflect the social, cultural, political, economic and technological changes shaping the Turkish society in these different time periods. The findings show that a socio-historically situated analysis of a brand’s packaging design transformation reveals the complex relationship between design and culture and provides clues to the market-society interface.

Originality/value

This study provides a comprehensive historical analysis of the visual identity evolution of the oldest Turkish pasta brand Piyale and contributes to research on packaging histories in the non-Western markets.

Abstract

Purpose

The purpose of this paper is to provide a method that allows the decollating of formerly monolithic services into separate modules. To provide a semantically equivalent decomposed model, structure and dependencies need to be defined. This fine‐grained image of the service allows an easier configuration and optimisation of single service modules and the service portfolio as a whole.

Design/methodology/approach

As an initial point of the work the authors conducted an extensive literature review, transferring insights from other domains that already make use of modularisation, such as industrial engineering and software engineering. The method developed on that basis was evaluated consecutively in use cases conducted with three companies.

Findings

As research in the fields of industrial and software engineering has shown, modularisation is a suitable approach for handling complexity. In this paper approaches and concepts of modularisation in industrial and software engineering were identified, adapted, and transferred into the field of service engineering, resulting in a method to modularise services. Additionally, potential positive effects of modularisation were compiled.

Research limitations/implications

The process of modularising in general requires three aspects: an architecture to describe the system's structure; interfaces to describe the interaction of modules; and standards for testing a module's conformity to the design rules. The method presented contributes primarily to the architecture. Further research efforts need to be conducted regarding aspects of interfaces and standards.

Practical implications

Nowadays, service providers are facing growing competition, which requires greater economical efficiency. Furthermore, customers increasingly demand individualised services, which can only be offered by applying the concepts of mass customisation. Both challenges can be met with the application of the concept of modularisation.

Originality/value

While service modularisation is increasingly discussed for the service domain, only little work has been done on presenting a method for a structured description. The provision of a method for describing the architecture of services and service portfolios can be used as the basis for further research regarding optimisation and configuration of service offers.

Abstract

Purpose

This purpose of this paper is to explore how Western design, fashion and aesthetic styles influenced advertising practice in Turkey in the post-Second World War era. Specifically, the authors focus on the key targets of the consumerist ideology of the period, women and discuss the representations of females in Turkish advertisements.

Design/methodology/approach

Data were analysed using a combination of social semiotic and compositional analysis methods. Compositional analysis focused on the formal qualities and design elements of the ads; social semiotic analysis sought to uncover their meaning potentials in relation to social, cultural, political and economic dynamics of the period. The advertisements of a prominent Turkish pasta brand, Piyale, published in the local adaptation of the American Life magazine, between 1956 and 1966, constitute the data set.

Findings

The analysis reveals that Piyale followed the stylistic and thematic trends prevailing in American and European advertisements at the time and crafted ads that constructed and communicated a Westernized image of Turkish women and families. In line with the cultural currents of the 1950s and 1960s, the ads emphasize patriarchal gender roles and traditional family values and address the woman as a consumer whose priority is to please her husband and take good care of her children.

Originality/value

This study contributes to the advertising history in non-Western contexts and provides an understanding of the influence Western advertising conventions and fashion trends had on developing country markets. The findings indicate that Western-inspired representations and gender roles dominated advertisements of local brands during the post-war period.

Abstract

Purpose

The salvation of human life is the goal of work for all rescue units. At the same time, a significant part of rescue operations is carried out in buildings or premises, which themselves are often in a state of destruction or are emergency ones. This paper aims to find how it is possible to carry out rescue operations in the face of the threat of constant collapse of the building.

Design/methodology/approach

To study the collapse hazard of the building, the information systems are used that display the process of rescue measures in case of a threat of deformation of the building in which there is a risk of burnback or destruction.

Findings

The findings show that the analysis of destruction parameters online allows using infrared sensors to form a picture of the allocation of places where people can be and thus saves lives while reducing the risk for the fire and rescue unit. To implement the presented format, it is proposed to use infrared sensors.

Originality/value

The use of infrared sensors allows online interaction with foci of dangerous situations and identifies the main aspects of the stratification of the preparation of the fire and rescue unit’s activities in conditions of increased danger.

Abstract

Purpose

This paper aims to examine how client requirements undergo representational and transformational shifts and changes in the design process and explore the consequence of such changes.

Design/methodology/approach

A series of design resources relating to hospital departmental configurations are examined and analysed using a social semiotic framework. The findings are supplemented by practitioner opinion.

Findings

Construction project requirements are represented and transformed through semiotic resource use; such representations deliver specific meanings, make new meanings and affect project relationships. Requirement representations may be understood as socially motivated meaning-making resources.

Research limitations/implications

The paper focuses on one set of project requirements: hospital departmental configurations from a National Health Service hospital construction project in the UK.

Practical implications

The use of semiotic resources in briefing work fundamentally affects the briefing and design discourse between client and design teams; their significance should be noted and acknowledged as important.

Social implications

The findings of the paper indicate that briefing and design work may be understood as a social semiotic practice.

Originality/value

This original paper builds upon scholarly work in the area of construction project communications. Its fine-grained analysis of briefing communications around representations of specific requirements is novel and valuable.
