Abstract

This article explodes traditional notions of ethnographic documentary, and instead positions the emerging practice of ethnocinema as a 21st century modality that falls within the paradigm of what Denzin calls the ‘eighth moment scholarship’ in this ‘fractured future’. Drawing on the monological, dialogic and imagistic ‘data’ from the ethnocinematic research project Cross‐Marked: Sudanese Australian Young Women Talk Education, the article uses ethnographic documentary film theory (including Minh‐ha, Rouch, and Aufderheide) and the critical pedagogical scholarship of McLaren to examine notions of performative identity construction and the possibility of intercultural identities and collaborations. Utilising the central metaphor of Minh‐ha’s ethnographic and filmic ‘zoo’, which cages those who are Othered by race, class, gender, sexuality and a myriad of differences, this article and ethnocinema overall seek to overthrow notions of difference, culture and community while recognising the increasingly prescient power of McLuhan’s dictum that the ‘medium is the message’ in this rhizomatic age.

Abstract

Purpose

This paper deals with numerical techniques dedicated to the predictive calculation of complex structures undergoing medium‐frequency vibrations. This field presents challenging difficulties. The first difficulty is the development of an efficient computational method because with the traditional finite element method (FEM), as the frequency increases, it becomes more expensive to control the pollution error. The second difficulty is the availability of sufficiently realistic joint models to take into account damping phenomena because in vibration problems dissipation controls the magnitude of the response directly.

Design/methodology/approach

We use the Variational Theory of Complex Rays (VTCR), an approach which effectively avoids the difficulties encountered with traditional FE techniques. Using two‐scale shape functions which verify the dynamic equation and the constitutive relation within each substructure, the VTCR can be viewed as a means of expressing the power balance at the different interfaces between substructures in variational form. New joint models which include heterogeneous mass, stiffness and damping are introduced to deal with the second difficulty.

Findings

This paper focuses on a new, substructured version of the VTCR which enables us to separate the realistically modeled substructures from the less accurate joints. The equations of the substructures are enforced exactly, whereas the interface equations are verified approximately through the minimization of an L2 residual. We show that this new formulation gives good results compared to the traditional VTCR or the FEM.

Practical implications

Although the examples presented in this paper are very simple, this new formulation shoult encounter no difficulties when dealing with more complex assemblies composed of several plates, beams, shells,…

Originality/value

This new, substructured VTCR approach provides more flexibility in the improvement of joint models, for example by carrying out experimental measurements on real structures.

Abstract

Purpose

The determination of the vibration induced by an aircraft impact on an industrial structure requires dynamic studies. The determination of the response by using classical finite element method associated with explicit numerical schemes requires significant calculation time, especially during the transient stage. This kind of calculation requires several load cases to be analyzed in order to consider a wide range of scenarios. Moreover, a large frequency range has to be appropriately considered and therefore the mesh has to be very fine, resulting in a refined time discretization. The purpose of this paper is to develop new ways for calculating the shaking of reinforced concrete structures following a commercial aircraft impact (see Figure 1). The cutoff frequency for this type of loading is typically within the 50-100 Hz range, which would be referred to as the medium-frequency range.

Design/methodology/approach

Taking into account this type of problem and assuming that the structure is appropriately sized to withstand an aircraft impact, the vibrations induced by the shock bring about shaking of the structure. Then these vibrations can travel along the containment building, as directly linked with the impact zone, but also in the inner part of the structure due to the connection with the containment building by the raft. So the excited frequency range, due to the impact of a commercial aircraft, contains two frequency ranges: low frequencies (less than ten wavelengths in the structure) and medium frequencies (between ten and 100 wavelengths). The strategy, which is presented in this paper, is inscribed in the context of the verification of inner equipment under this kind of shaking. The non-linear impact zone is assumed to have been delimited with classical finite element simulations. In this paper the authors only focus on the response of the linear part of the structure. This phenomenon induces a non-linear localized area around the impact zone.

Findings

So the medium frequencies can therefore induce significant displacements and stresses at the level of equipment and thus cause damage if the structure is not dimensioning to this frequency range.

Research limitations/implications

In this context the use of finite elements method for the resolution of the shaking implies a spatial discretization in correlation with the number of wavelengths to represent, and thus a long computation time especially for medium frequencies. That is why in the case of a coarse mesh the medium-frequency range is ignored. For example, a concrete structure with a characteristic dimension of about 30 and 1 m of thickness, may not represent frequencies higher than 16 Hz with a mesh size of 1 m (assuming ten elements per wavelength).

Practical implications

The paper includes implications for proper dimensioning civil engineering structures subjected to a load case containing a large frequency range.

Originality/value

This paper shows the gain of the strategy using appropriate method to medium frequencies compared to conventional method such as finite elements.

Abstract

The social licence literature contains two quite different accounts of the concept. Sometimes social licence is presented as an essentially empirical matter; sometimes it is portrayed as having normative significance. Both advocates and critics assume that the normative version is easy to generate from the empirical version but the author argues that it is difficult to account for the normativity of social licence. It is commonly claimed that social licence is a ‘metaphor’ or ‘analogy’ drawing on familiar understandings of institutional licences, and standard accounts purport to ‘build in’ normativity. Neither strategy establishes the normativity of social licence. If that is correct, we have reason to be sceptical about the normative significant of claims about the possession of empirical social licence. The approval or acceptance by affected communities may be one factor to be taken into account in such analysis, but it will not itself settle whether a practice ought to be approved or accepted or licenced.

Abstract

A new approach called the “variational theory of complex rays” (VTCR) is developed for calculating the vibrations of weakly damped elastic structures in the medium‐frequency range. Here, the emphasis is put on the most fundamental aspects. The effective quantities (elastic energy, vibration intensity, etc.) are evaluated after solving a small system of equations which does not derive from a finite element discretization of the structure. Numerical examples related to plates show the appeal and the possibilities of the VTCR.

Abstract

The work of Henri Lefebvre Rhythmanalysis, Space, Time and Everyday Life (2004) is generally known as the original proposer of rhythmanalysis, inspired by the last chapter of Gaston Bachelard's book La dialectique de la durée (1963), entitled ‘Rhythmanalysis’. Nevertheless, it was the Portuguese philosopher Lúcio Pinheiro dos Santos who developed the notion of rhythmanalysis. In this chapter I address this episode of the genealogy of rhythmanalysis aiming to contribute to a broader understanding of its context of origin. I also present fragments of a rhythmanalysis exercise developed in Caminito, Buenos Aires, as part of my research in the field of art studies. Following a pre-Platonic notion of rhythm (Benveniste, 1966), I draw on those fragments as much as on the reflexive confrontation of rhythmanalysis with feminist and ch'ixi epistemologies (e.g., Haraway, 1988; Rivera, 2018) in order to propose what I come to call rhuthmanalysis.

This paper aims to develop an efficient numerical method for mid-frequency analysis of built-up structures with large convex uncertainties.

Abstract

Purpose

This paper aims to develop an efficient numerical method for mid-frequency analysis of built-up structures with large convex uncertainties.

Design/methodology/approach

Based on the Chebyshev polynomial approximation technique, a Chebyshev convex method (CCM) combined with the hybrid finite element/statistical energy analysis (FE-SEA) framework is proposed to fulfil the purpose. In CCM, the Chebyshev polynomials for approximating the response functions of built-up structures are constructed over the uncertain domain by using the marginal intervals of convex parameters; the bounds of the response functions are calculated by applying the convex Monte–Carlo simulation to the approximate functions. A relative improvement method is introduced to evaluate the truncated order of CCM.

Findings

CCM has an advantage in accuracy over CPM when the considered order is the same. Furthermore, it is readily to consider the CCM with the higher order terms of the Chebyshev polynomials for handling the larger convex parametric uncertainty, and the truncated order can be effectively evaluated by the relative improvement method.

Originality/value

The proposed CCM combined with FE-SEA is the first endeavor to efficiently handling large convex uncertainty in mid-frequency vibro-acoustic analysis of built-up structures. It also has the potential to serve as a powerful tool for other kinds of system analysis when large convex uncertainty is involved.

Abstract

Purpose

The purpose of this paper is to examine the causal correlation between the work stress of immigration officers (IOs) and the cross-level effect of social support.

Design/methodology/approach

A multilevel model was used to analyze the quantitative data obtained from 231 IOs in Taiwan, who served as the research objects.

Findings

From the results of this study, it was found that a positive significant relationship existed between role conflict and work stress, as well as between work stress and job burnout. Also, cross-level context and moderating effect for the relationship between social support and work stress, as well as between social support, work stress and job burnout were obtained.

Originality/value

This study only considered IOs in airports and ports. Therefore, it is necessary to determine if other topics of organizational behavior, such as the leadership of supervisors, organizational climate and work values of IOs, have a positive moderating effect. In this regard, it is recommended that a longitudinal study should be conducted in the future.

Abstract

Purpose

Notwithstanding the findings of several published articles on human capital, there is scarcity of a comprehensive instrument to measure it. In this direction, the objective of present research is to develop a valid and reliable scale to assess human capital.

Design/methodology/approach

This research was divided into two parts. Study 1 focused on literature review of human capital measures, development of items and exploring the factor structure of human capital construct on a sample of 184 employees. Study 2 was based on the survey of 212 employees, and reliability assessment and confirmatory factor analysis was performed to validate the factor structure of human capital construct.

Findings

The findings can be summarized in two ways. Study 1 present that human capital scale is multidimensional consisting of employee capability, leadership and motivation, employee satisfaction and creativity. The findings of study 2 confirms the validity and reliability of three factor structure of human capital construct consisting of 18 items in total.

Practical implications

The study provides a multidimensional psychometric instrument which can help in measuring the human capital of the organization from the perspective of capabilities, satisfaction and creativity and leadership and motivation. Moreover, it can serve as an aid to human resource (HR) and human resource development (HRD) professionals for human capital assessment in the organizations.

Originality/value

This study provides a measure to assess human capital in Indian manufacturing sector organizations that makes a novel contribution to the area.

Abstract

Purpose

Inspired by an exciting revival of interest in the working methods and processes of the creative arts, the purpose of this paper is to make use of the auteur approach to film production, to further develop knowledge about sensuous methodologies in qualitative research.

Design/methodology/approach

An exegesis of the authors’ particular experiences in producing and disseminating a short documentary film is used to construct a framework from which to analyse affective modes of engagement within the parameters of qualitative research.

Findings

Qualitative researchers are characterised as creative artists who bring their precise aesthetic choice to bear on an audience through a mix of technical competence, distinguishable personality and interior meaning.

Practical implications

One way for qualitative research to have affective impact is to use the working methods and procedures of the creative arts.

Social implications

A research culture is required where risk is permissible and engagement with the creative arts is given greater recognition in future qualitative projects.

Originality/value

As a mode of creative arts enquiry, film making can allow a degree of the emotional meaning and feeling within a study to come through into the analysis and the viewer's/reader's affective experience. This is often difficult to come by in more scientifically‐driven research approaches.
