Abstract

In this chapter, we address the question if and how modern technology can be used to design questionnaires, diaries, web sites, and experiments to improve the validity of reliability of active data collection instruments. In particular, it discusses the history of computer-assisted activity diary data, reenactment sessions, stated preference methods, and interactive computer experiments with a special focus on the design of these instruments in terms of respondent support and user interfaces. Empirical evidence and experience suggests that although fascinating instruments may increase respondent motivation and involvement and therefore improve the reliability of the measurements, there is also the danger that respondents' answers are influenced by features of the electronic instrument that are not essential, reducing validity and reliability.

Abstract

Purpose

Aims to evaluate the impedance of a rapidly‐evolving corrosion cell by developing an alternative method to the traditional frequency domain method, and to present a new method to analyze the coulostatically‐induced transient (CIT).

Design/methodology/approach

The coulostatic impulse signal was used to obtain the CIT. By transforming the CIT from the time domain into the frequency domain, the coulostatically induced impedance spectrum (CIS) can be obtained, which contributes to the evaluation of the impedance of the electrode and of its corrosion processes. The equations for the coulostatic response also can be obtained by using network analysis in the Laplace domain.

Findings

Obtaining the CIS of an electrode in the time domain can facilitate accurate evaluation of metal corrosion rate in a rapidly evolving system. Compared with the traditional method for deriving CIT equations, the proposed method based on network analysis is convenient for more complex circuit models to obtain the CIT equation.

Research limitations/implications

It is difficult to obtain an impedance spectrum over a wide range of frequencies by the coulostatic measurement at one time, which perhaps limits its usefulness in systems with longer time constants.

Practical implications

The proposed method is advantageous compared with traditional analysis methods of CIT, because analysis of CIS can be conducted using commercial software and dispenses with the need for personal software to be developed, which greatly facilitates the interpretation of the coulostatic measurements involving multi‐time constants.

Originality/value

It is possible that the present work may pave the way for further work to investigate more complex corrosion systems by means of CIS.

Abstract

It is shown that a reduction of the bending moments in a helicopter rotor blade may be achieved by replacing an elastic beam‐type flapping hinge by a stack of leaf‐springs having the same overall bending stiffness but no shear stiffness. This reduction becomes more pronounced when the tensile load on the flapping hinge is increased.

Abstract

This chapter sheds light on long-term trends in the level and structural dynamics of investments in Russian human capital formation from government, corporations, and households. It contributes to the literature discussing theoretical issues and empirical patterns of modernization, human development, as well as the transition from a centralized to a market economy. The empirical evidence is based on extensive utilization of the dataset introduced in Didenko, Földvári, and Van Leeuwen (2013). Our findings provide support for the view expressed in Gerschenkron (1962) that in late industrializers the government tended to substitute for the lack of capital and infrastructure by direct interventions. At least from the late nineteenth century the central government's and local authorities' budgets played the primary role. However, the role of nongovernment sources increased significantly since the mid-1950s, i.e., after the crucial breakthrough to an industrial society had been made. During the transition to a market economy in the 1990s and 2000s the level of government contributions decreased somewhat in education, and more significantly in research and development, but its share in overall financing expanded. In education corporate funds were largely replaced by those from households. In health care, Russia is characterized by an increasing share of out-of-pocket payments of households and slow development of organized forms of nonstate financing. These trends reinforce obstacles to Russia's future transition, as regards institutional change toward a more significant and sound role of the corporate sector in such branches as R&D, health care, and, to a lesser extent, education.

Abstract

This research explores two interconnected questions: (1) How do we approach stylistic features of multimodal rhetorical artifacts such as protest posters? (2) Do said artifacts designed for different purposes exhibit systematic stylistic differences? Drawing on Charles Sanders Peirce’s semiotic categorization, this study develops a framework for examining concision, one of the primary stylistic considerations for multimodal rhetorical artifacts such as protest posters. This paper illustrates the use of this framework by exploring the correlation between rhetorical purpose and concision in posters created and disseminated before and during the 2011–2012 Québécois student movement. This study fine-tunes our existing knowledge on multimodality with style sensitivity, and demonstrates how an economy-of-sign based semiotic approach could enrich the empirical examination of multimodal rhetorical artifacts by generating more controlled interpretations.

Abstract

The author focusses on corporate history from a media aesthetic perspective using the case of the Danish brewer Carlsberg. Through a careful examination of the company’s website that draws on Kress and Van Leeuwen’s work on modality, the author examines how images and symbols of the past and present are intertwined so as to ‘curate’ history and present the brand as both deeply rooted and authentic.

Abstract

Purpose

The purpose of this paper is to examine the representations of male and female social actors within the subversive gendered discourse of “equal opportunities for men and women” in Iranian English as a foreign language (EFL) textbooks.

Design/methodology/approach

From the methodological perspective, this study fused van Leeuwen’s (2003) “Social Actor Network Model” and Sunderland’s (2004) “Gendered Discourses Model”.

Findings

Data obtained from this study showed the subversive gendered discourse of “equal opportunities” was supported through such representations within a narrow perspective in line with dominant gender ideologies in Iran. The findings suggest the resistance against such subversive gendered discourse in Iranian EFL textbooks underpins gender norms and religious ideologies existing in Iran.

Originality/value

Such representations of male and female social actors in school textbooks show inclusive education and the discourse of “equal opportunities” have yet to be realised in education system of many countries, including Iran.
