Abstract

Purpose

An experimental investigation of hemispherical forebody interaction effects on the drag coefficient of a D-shaped model is carried out for three-dimensional flow in the subcritical range of Reynolds number 1 × 105 ≤ Re ≤ 1.8 × 105. To study the interaction effect, hemispherical shapes of various sizes are attached to the upriver of the D-shaped bluff body model. The diameter of the hemisphere (b1) varied from 0.25 to 0.75 times the diameter of the D-shaped model (b2) and its gap from the D-shaped model (g/b2) ranged from 0.25 to 1.75 b2.

Design/methodology/approach

The experiments were carried out in a low-speed open-circuit closed jet wind tunnel with test section dimensions of 1.2 × 0.9 × 1.8 m (W × H × L) capable of generating maximum velocity up to 45 m/s. The wind tunnel is equipped with a driving unit which has a 175-hp motor with three propellers controlled by a 160-kW inverter drive. Drag force is measured with an internal six-component balance with the help of the Spider 3013 E-pro data acquisition system.

Findings

The wind tunnel results show that the hemispherical forebody has a diameter ratio of 0.75 with a gap ratio of 0.25, resulting in a maximum drag reduction of 67%.

Research limitations/implications

The turbulence intensity of the wind tunnel is about 5.6% at a velocity of 18 m/s. The uncertainty in the velocity and the drag coefficient measurement are about ±1.5 and ±2.83 %, respectively. The maximum error in the geometric model is about ±1.33 %.

ractical implications

The results from the research work are helpful in choosing the optimum spacing of road vehicles, especially truck–trailer and launch vehicle applications.

Social implications

Drag reduction of road vehicle resulting less fuel consumption as well as less pollution to the environment. For instance, tractor trailer experiencing approximately 45% of aerodynamics drag is due to front part of the vehicle. The other contributors are 30% due to trailer base and 25% is due to under body flow. Nearly 65% of energy was spent to overcome the aerodynamic drag, when the vehicle is traveling at the average of 70 kmph (Seifert 2008 and Doyle 2008).

Originality/value

The benefits of placing the forebody in front of the main body will have a strong influence on reducing fuel consumption.

Abstract

The manoeuvring of everyday spaces to nudge the population towards a physically active lifestyle or active living has been the hallmark of the policy modes of instrumental thinking for combating physical inactivity, particularly in urban spaces across the world. Thus, the active promotion of fitness activities by the postcolonial state signifies the centrality of the body in disciplining docile and inactive individuals to produce fit and active citizens. Such a population-based approach has often raised concerns about social and spatial justice and expressions of identity, liberty, and surveillance, even as everyday spaces in cities continue to exhibit elements of colonial governmentality. In the midst of this, the body continues to be central to the ways in which such a population makes sense of being physically active and ‘being healthy’ in their everyday lives. By employing a multi-sited ethnography conducted over a period of 10 months in different public parks in Delhi, the present chapter aims to understand the ways in which fitness activities are performed, produced, and practised in the city. While public parks themselves are a product of colonial urban governmentalities in Delhi, this chapter argues that active bodies engaged in everyday sports in the parks also emerge as the critical site for the bodily inscription of global standards of physical activity. Driven by Western fitness regimes, individuals tend to understand themselves as entrepreneurial selves that can bring to life this imagination of the body ideal even while being engaged in various fitness and leisure activities aimed at being ‘healthy’.

Abstract

The body has been one of the central tools in analysing connections between sport and postcolonialism in India, given how sport was an essential part of the colonial ‘civilising’ mission, which involved disciplining and controlling Indian bodies. Any discursive understanding of sport and postcolonialism in India must consider how it relates to existing concepts of the body and shapes the experiences of the people involved in it – acknowledging not just the power of colonialism in moulding sporting experiences but also the force of internal hierarchies that exist in Indian society. This chapter explores the experiences of students who studied in higher educational institutions in Kerala under the ‘sports quota’, a system that reserves seats in colleges/universities for high-performing sportspersons in India. Through their interviews, the sustained exclusion of the sporting body in contemporary Indian pedagogy is illustrated here. Specifically, the continuing prevalence of the colonial emphasis on the sporting body, as one whose strength and instrumentality are paramount, as well as its corollary postcolonial position, which treats this sporting body as inferior to the ‘refined mind’ of studious pupils, can be observed. Approaching the sports quota with a decolonising lens would require re-examining the disembodied nature of pedagogy in India’s higher educational institutions, acknowledging sporting students’ lived experiences, and a seamless integration – as opposed to separation/exclusion – of the sportsperson into higher education.

Abstract

Fairy tales and their movie counterparts have, for decades, been a means of socialising children and audiences regarding gender (e.g., Shewmaker, 2015; Whitley, 2013). Specifically, Disney movies that portray fairy tales have strongly influenced how young children learn gender roles and gendered behaviours, yet deeper examination is needed of how Disney portrayals of masculinities have evolved among these films and across character type to understand how Disney may be reflecting or impacting dominant representations of masculinity that privilege certain identities and characteristics over others (Brode, 2016). While previous work has examined Pixar films as socio-culturally meaningful for representations of boyhood that remain grounded in traditional, hegemonic notions of masculinity (Wooden & Gillam, 2014), this chapter adds to the body of work by employing a critical content analysis of Disney films from Snow White and the Seven Dwarfs to Disney's most recent addition of Strange World to answer the questions about how masculinities are portrayed. Through answering these questions of evolved representation throughout close to a century amount of work, we contribute to scholarship that attempts to understand media influences on boyhood culture, which is considered in crisis due to overemphasised representations of powerful, strong male characters that hide their emotions (Brode, 2016; Wooden & Gillam, 2014).

Abstract

In the past 10 years, the scale of running events in China has increased dramatically, and the forms of running events have also become rich and diverse. Running is not only a social phenomenon but also a historical and cultural phenomenon as an organic part of human culture with its own sociological values in China. This chapter offers insight into the development of Chinese running culture and how this has emerged from ancient and modern Chinese running cultures based on Foucault's disciplinary power theory, biopower and the technologies of the self. This chapter argues that running culture in China constructs the subjectivity of the Chinese runners under the joint action of the technologies of power and the technologies of the self. The findings acknowledge how Chinese Runners present and express themselves by showing a ‘sense of presence’. Runners illustrate the implicit or explicit meaning and value of a particular way of life through running. Runners regard running as the technology of the self for self-expression and self-creation so that individuals can control their bodies and soul, thoughts, behaviours and ways of existence. Emerging technologies of power provide possibilities for the production of running culture in China, and the current policy under the technologies of power meets the needs of runners. In Chinese running culture, power was not oppressive but productive.

Abstract

Sport organizations hold substantial ideological power to showcase and reinforce dominant cultural ideas about gender. The organization and portrayal of sporting events and spaces continue to promote and reinforce a hierarchical gender binary where heroic forms of masculinity are both desired and privileged. Such publicly visible gender hierarchies contribute to the doing of gender beyond sport itself, extending to influence gender power relations within sport and non-sport organizations. Yet, there has been a relative absence of scholarship on sport organizations within the organizational sociology field. In this paper, we review findings of studies that look at how formal and informal organizational dimensions influence the doing and undoing of gender in sport organizations. Subsequently, we call for scholars to pay more attention to sport itself as a source of gendered organizational practices within both sport and non-sport organizations. We end with suggestions for research that empirically explores this linkage by focusing on innovative theoretical perspectives that could provide new insights on gender inclusion in organizations.

Abstract

Purpose

This study aims to explore and segment consumer preferences for electric and hybrid vehicles in Germany, Sweden, the Netherlands and Turkey, focusing on understanding the various factors that influence consumer decisions in these markets.

Design/methodology/approach

Using latent class analysis (LCA) on data collected through online surveys and discrete choice experiments, this research categorizes consumers into distinct segments. The approach allows for a nuanced understanding of how various factors such as income level, fuel cost, age, CO2 emissions, purchase price, vehicle range, policy policies and environmental concerns interact with shape consumer preferences.

Findings

The analysis uncovers significant heterogeneity in consumer preferences for electric and hybrid vehicles across Germany, Sweden, the Netherlands and Turkey, revealing four key segments: “Eco-Driven Innovators,” “Value-Focused Pragmatists,” “Tech-Savvy Early Adopters” and “Reluctant Traditionalists.” “Eco-Driven Innovators” prioritize environmental benefits and are less sensitive to price, demonstrating a strong inclination toward vehicle CO2 emissions and policy policies. “Value-Focused Pragmatists” weigh economic factors heavily, showing a sharp interest in fuel costs and purchase prices but are open to considering electric and hybrid vehicles if they present clear long-term savings. Technology-savvy early adopters are attracted by the latest technological advancements in vehicles, regardless of the type, and are motivated by factors beyond just environmental concerns or cost savings. Lastly, “Reluctant Traditionalists” exhibit minimal interest in electric and hybrid vehicles due to concerns over charging infrastructure and upfront costs. This detailed segmentation illustrates the diverse motivations and barriers influencing consumer choices, from governmental policies and environmental concerns to individual financial considerations and technological appeal.

Originality/value

This study stands out for its pioneering application of LCA to dissect the complexity of consumer preferences for electric and hybrid vehicles, a methodological approach not widely used in this research domain. Using LCA, the authors are able to uncover nuanced consumer segments, each with distinct preferences and motivations, providing a depth of insight into market dynamics that traditional analysis methods may overlook. This approach enables a more granular understanding of how diverse factors – ranging from environmental concerns to economic considerations and technological attributes – interact to shape consumer choices in different countries. The findings not only fill a critical gap in the existing literature by mapping the intricate landscape of consumer preferences, but also offer a novel perspective on strategizing market interventions. Therefore, the application of LCA enriches the discourse on sustainable transportation, offering stakeholders, manufacturers, policymakers and researchers – a refined toolkit for navigating the evolving market dynamics and fostering the adoption of electric and hybrid vehicles.

Abstract

Purpose

The purpose of this multi-voiced paper is to propose a prosocial paradigm for the field of performance management and management control systems. This new paradigm suggests cultivating prosocial behaviour and prosocial groups in organizations to simultaneously achieve the objectives of economic performance and sustainability.

Design/methodology/approach

The authors share a common concern about the future of humanity and nature. The authors challenge the influential assumption of economic man from neoclassical economic theory and build on evolutionary science and the core design principles of prosocial groups to develop a prosocial paradigm.

Findings

Findings are based on the premise of the prosocial paradigm that self-interested behaviour may outperform prosocial behaviour within a group but that prosocial groups outperform groups dominated by self-interest. The authors explore various dimensions of performance management from the prosocial perspective in the private and public sectors.

Research limitations/implications

The authors call for theoretical, conceptual and empirical research that explores the prosocial paradigm. They invite any approach, including positivist, interpretive and critical research, as well as those using qualitative, quantitative and interventionist methods.

Practical implications

This paper offers implications from the prosocial paradigm for practitioners, particularly for executives and managers, policymakers and educators.

Originality/value

Adoption of the prosocial paradigm in research and practice shapes what the authors call the prosocial market economy. This is an aspired cultural evolution that functions with market competition yet systematically strengthens prosociality as a cultural norm in organizations, markets and society at large.

Abstract

Purpose

Are there smart ways to find heuristics? What are the common principles behind heuristics? We propose an integrative definition of heuristics, based on insights that apply to all heuristics, and put forward meta-heuristics for discovering heuristics.

Design/methodology/approach

We employ Herbert Simon’s metaphor that human behavior is shaped by the scissors of the mind and its environment. We present heuristics from different domains and multiple sources, including scholarly literature, practitioner-reports and ancient texts.

Findings

Heuristics are simple, actionable principles for behavior that can take different forms, including that of computational algorithms and qualitative rules-of-thumb, cast into proverbs or folk-wisdom. We introduce heuristics for tasks ranging from management to writing and warfare. We report 13 meta-heuristics for discovering new heuristics and identify four principles behind them and all other heuristics: Those principles concern the (1) plurality, (2) correspondence, (3) connectedness of heuristics and environments and (4) the interdisciplinary nature of the scissors’ blades with respect to research fields and methodology.

Originality/value

We take a fresh look at Simon’s scissors-metaphor and employ it to derive an integrative perspective that includes a study of meta-heuristics.
