Abstract

In this chapter we approach the estimation of dynamic stochastic general equilibrium models through a moments-based estimator, the empirical likelihood. We attempt to show that this inference process can be a valid alternative to maximum likelihood, which has been one of the preferred choices of the related literature to estimate these models. The empirical likelihood estimator is characterized by a simple setup and only requires knowledge about the moments of the data generating process of the model. In this context, we exploit the fact that these economies can be formulated as a set of moment conditions to infer on their parameters through this technique. For illustrational purposes, we consider a standard real business cycle model with a constant relative risk averse utility function and indivisible labor, driven by a normal technology shock.

Abstract

This chapter proposes a simple, fairly general, test for global identification of unconditional moment restrictions implied from point-identified conditional moment restrictions. The test is a Hausman-type test based on the Hausdorff distance between an estimator that is consistent even under global identification failure of the unconditional moment restrictions, and an estimator of the identified set of the unconditional moment restrictions. The proposed test has a χ2 limiting distribution and is also able to detect weak identification. Some Monte Carlo experiments show that the proposed test has competitive finite sample properties already for moderate sample sizes.

Abstract

In the introduction to Beyond Bombshells, Jeffrey A Brown lists examples of blockbuster films with leading female heroines and proclaims that they have ‘challenged the assumption that action movies are a strictly male domain’ (2015, p. 6). His examples include, but are not limited to, the Kill Bill films (2003, 2005), The Hunger Games (2012), Brave (2012) and Snow White and the Huntsman (2012), all of which demonstrate the rise in popularity of the woman-led action film. However, these films also demonstrate a reluctance of the action film to detach itself from masculinity. Despite their female leads, these action films still foreground masculinity. The films have darker colour palettes and their female leads tend to have masculine coded traits and hobbies, suggesting that women can succeed within this genre only by distancing themselves from femininity.

This chapter analyses the subversion of the genre conventions of action by exploring the use of feminine objects in director Cathy Yan's Birds of Prey: And the Fantabulous Emancipation of One Harley Quinn (2020). Written and directed by women, Birds of Prey is a notable turn in the action genre as it makes use of feminine objects (hair ties, glitter, fashion, jewellery) within action sequences that don't just allow a female presence within the action, but centre feminine power. By relocating femininity and masculinity to objects rather than bodies, new ways of understanding how genre conventions are not fixed but fluid are opened up for further exploration.

Abstract

This paper examines Aman Ullah’s contributions to robust inference, finite sample econometrics, nonparametrics and semiparametrics, and panel and spatial models. His early works on robust inference and finite sample theory were mostly motivated by his thesis advisor, Professor Anirudh Lal Nagar. They eventually led to his most original rethinking of many statistics and econometrics models that developed into the monograph Finite Sample Econometrics published in 2004. His desire to relax distributional and functional-form assumptions lead him in the direction of nonparametric estimation and he summarized his views in his most influential textbook Nonparametric Econometrics (with Adrian Pagan) published in 1999 that has influenced a whole generation of econometricians. His innovative contributions in the areas of seemingly unrelated regressions, parametric, semiparametric and nonparametric panel data models, and spatial models have also inspired a larger literature on nonparametric and semiparametric estimation and inference and spurred on research in robust estimation and inference in these and related areas.

Abstract

Purpose

The purpose of this paper is to explore the possibility of designing training sessions on the basis of a dramatic structure and inclusion of contextual narrative for facilitating transfer of learning. The role of stimulating curiosity in this process has also been scanned under the lens of neurobiological insights.

Design/methodology/approach

The paper theoretically develops a framework through an integrative literature review to examine the prospect of enhanced learner engagement through structure, narrative and some interdisciplinary theories, namely, the gap theory of curiosity and the peak end theory.

Findings

A contextual story-based training method designed on the basis of a dramatic plot structure can leverage on the learners’ emotions for engaging learning sessions and retention of content. Such design offers potential to improvise and strengthen the overall training module design and delivery mechanism. The outcome is seen through enhanced peak moments of curiosity and satisfaction, thus enriching the overall training–learning process.

Research limitations/implications

The study is theory based and non-empirical which does not give it a ground to make generalised statements and conclusions. This factor, however, paves the way for future research in the allied areas such as empirical testing of the framework by identifying and testing the variables and other contextual and causal factors.

Practical implications

The suggested framework has practical implications for Learning and Development managers as well as academies. The conceptual framework provided in this work can lend some unique insights towards strengthening the training–learning process.

Originality/value

Although the concept of using stories for training is not new, this study contributes by proposing a new theoretical framework that examines together the elements of sound dramatic structure and a story-based training method. Such a design, conceived by taking into account an understanding of the working mind, can influence the overall experience of achieving positive training–learning results.

Abstract

Purpose

The purpose of this paper is to present two examples how stories and storying can be utilised to excavate forgotten points and junctures that result as fundamental episodes in the forming of the subjective selves. Writing in-between masculinity and queerness both stories trace the experience of two boys through accounts of initiation and subjection.

Design/methodology/approach

Using autobiography as a method, in concert with Deleuzian-Guattarian notions of becoming and becoming other the paper explores how the discovery of subjective difference informs how the work of identity making and survival take place.

Findings

What is uncovered in the process of the paper is how we learn the disguises needed for survival through an early encounter away from the dominating and into the dominated. In this process of becoming other strategies are designed to disguise difference and avoid detection.

Social implications

The gaps and fissures that exist between intergenerational positions in conjunction with the straight/gay sexuality binary provide the environment within which the paper operates. Through personal biography the paper investigates how this structure informs the subjective positionality and the identity construction.

Originality/value

The openness of the writing found in both of these accounts, although clearly a narrative construction, are also akin to a stream of remembering or spontaneous prose writing. The accounts themselves are not heavily edited; they have not been figured and refigured to produce pleasing literary effects. Instead they remain raw utilising narrative tropes such as flash-back and dramaturgy simply as conduits to memory. The tropes that are employed could be read as defensive or distancing mechanism, a protection against the capacity of the unfolding lived experience to disturb and disrupt.

Abstract

Purpose

The purpose of this paper is to analyse job ads as relatively accessible indicators of the knowledge, skills and competencies required of librarians by employers. It then uses a framework provided by the literature on professional jurisdiction to examine what may be trends and shaping factors for the Library and Information Studies (LIS) profession with regard to jurisdiction in a changing information landscape.

Design/methodology/approach

Job ads were examined in two separate studies; one comparing job ads in Australia and the USA over eight weeks in 2004, and the other looking at one month snapshots of Australian job ads in 1974, 1984, 1994 and 2004. The text from the job ads was analysed using a content analysis software package. The literature on professional jurisdiction provided an interpretive framework.

Findings

The Australian snapshots over time showed that there is an increasing lack of clarity about the skills and competencies required of librarians. The American job ads seemed to rank jurisdictional knowledge and professional qualifications more highly than their Australian counterparts. Interpersonal skills, behavioural characteristics and technical services skills are in demand in both countries.

Originality/value

In addition to reporting on the knowledge, skills and competencies required of librarians, by applying an interpretive framework from the literature on professional jurisdiction the paper exposes some of the challenges ahead for the LIS profession. Research limitations/implications – The research used a small number of sources and a relatively small number of ads. It is acknowledged that job ads are only one source of information about knowledge, skills and competencies.

Abstract

Purpose

The goal of the paper is to introduce a new method of obtaining equivalent dynamic model of electromagnetic field quantities. Proposed algorithm allows approximation of the frequency and step response by a simple inertial element model, with adjustable rank and delay. The values of the model parameters may be also used to describe the dynamics of considered system.

Design/methodology/approach

The dynamics of interesting field quantity in certain space location may be represented by an equivalent model of inertial element. Parameters of the model are identified using the solution of the problem in quasi‐stationary conditions for very limited number of excitation frequencies. These solutions are further used to build a matching approximation of real frequency response function (FRF).

Findings

The proposed method allows fast approximation of transient states of linear vector field. It may be useful with fast and relatively precise estimation of dynamic parameters of the electromagnetic field, e.g. in screening and eddy current problems.

Research limitations/implications

The main limitation of the method is the assumption of linearity of the problem. However, many practical tasks similar to the examples presented in the paper can be considered highly linear.

Practical implications

The main advantage of the method is that it allows fast estimation of the field dynamics without either solving the problem for whole range of frequencies or computing the transient state in time domain. It does not need the access to the original mass and stiffness matrices. Therefore, it may be used with commercial FEM software, which usually restricts access to its internal data.

Originality/value

The method is based on well known concept of moments, but the use of existing stationary FEM solutions for approximating transient states is a novel approach. Proposed procedure may be easily automated for the simulation environments with scripting capabilities.

Abstract

The decision on which countries will participate in European Monetary Union (EMU) is to take place as early as possible in 1998, with the final run in, regarding the technicalities of introducing a single currency, starting on 1 January 1999. With this timetable in mind, examines some of the major issues which will have to be confronted by UK retailers. Even if the UK Government decides to opt out, the increasing internationalization of retailing will mean that UK retailers will have to face a Euro‐denominated environment over a significant range of its business activities. Consequently, by identifying EMU factors which specifically relate to retailing, identifies the key areas which retailers need to consider in planning a strategy to take account of the possibility that EMU will take place in at least some major EU economies.
