Bangkok : formes du commerce et évolution urbaine

Davisi Boontharm, architecte, étudie dans cette thèse la ville de Bangkok comme un espace urbain en mouvement, à travers les lieux et les formes du commerce. Elle porte une attention particulière à la place qu'il occupe dans le dynamisme urbain. Elle cherche à comprendre comment les modèles de la ville coexistent et se coproduisent pour former des tissus et des systèmes originaux

Crushing modes of aluminium tubes under axial compression

A numerical study of the crushing of circular aluminium tubes with and without aluminium foam fillers has been carried out to investigate their buckling behaviours under axial compression. A crushing mode classification chart has been established for empty tubes. The influence of boundary conditions on crushing mode has also been investigated. The effect of foam filler on the crushing mode of tubes filled with foam was then examined. The predicted results would assist the design of crashworthy tube components with the preferred crushing mode with the maximum energy absorption.

Prelude to the birth of Wayo-Secchu (Japanese hybrid style) in Japanese early modern architecture

This paper will investigate the background of the emergence of Wayo-secchu (Japanese Hybrid Style), by re-examining the rhetoric of the government-oriented early Meiji Western style architecture and Japanese traditionalism's reaction to it. I will elucidate the undercurrent of the intentional shift in nineteenth-century Japan towards the recuperation of traditional Japanese style, a shift which initiated the Japanese hybrid style we now call Wayo-secchu. I will discuss the effect of institutional pressure to Westernize, by investigating what was meant by a new architectural method as expressed by the government of the time.

Professionalisation and public relations : an ethical mismatch

This paper explores the ethical culture in which contemporary public relations practitioners’ work and how it relates to the professionalisation of the domain. Focusing on the international umbrella public relations institution Global Alliance (GA) and other important industry bodies such as the Public Relations Institute of Australia (PRIA) and Public Relations Institute of New Zealand (PRINZ), we study how the ‘work’ of a public relations practitioner is described, and as a corollary, what professional and ethical standards are promoted. Our analysis draws on theories of professions (Abbott 1988; Anderson and Schudson 2009; Volti 2008) and narrative (Surma 2004, Herman 2009), and argues that key elements of professionalisation in public relations contribute to a normative culture which is potentially at odds with notions of ethical communication. We suggest public relations needs to engage more rigorously with professional values to develop, effectively, ethical practice and be normatively aligned with other professions.

Least squares asymptotics in spurious and cointegrated panel regressions with common and idiosyncratic stochastic trends

This article makes an analytical study of the effects of the presence of both common and idiosyncratic stochastic trends on the pooled least squares estimator. The results suggest that the usual result of asymptotic normality depends critically on the absence of the common stochastic trend.

On the estimation and inference in factor-augmented panel regressions with correlated loadings

In an influential paper, Pesaran [Pesaran, M.H. (2006). Estimation and inference in large heterogeneous panels with a multifactor error structure. Econometrica 74, 967–1012] proposes a very simple estimator of factor-augmented regressions that has since then become very popular. In this note we demonstrate how the presence of correlated factor loadings can render this estimator inconsistent.

Invasion from the skies

Increased competition and shrinking budgets have forced public service broadcasters around the world to reconsider their role. Doordarshan, India’s public service television network, shares the problems faced by its counterparts in more developed countries. Although it continues to enjoy the luxury of being the only television network broadcasting its programs from within national boundaries, it has had to change its policies and programming to compete with foreign television channels including Murdoch’s Star TV. However, it is the Indian audience that has benefited most from this competition from the skies in the form of improved quality and quantity of programs. This paper reports on an audience survey carried out in India earlier this year to gauge television viewers’ perception of these benefits. The paper also gives background on the developments in thetelevision industry in India.

Cross-sectional averages versus principal components

In spite of the increased use of factor-augmented regressions in recent years, little is known regarding the relative merits of the two main approaches to estimation and inference, namely, the cross-sectional average and principal component estimators. By providing a formal comparison of the approaches, the current paper fills this gap in the literature.

Application of air quality combination forecasting to Bogota

The bulk of existing work on the statistical forecasting of air quality is based on either neural networks or linear regressions, which are both subject to important drawbacks. In particular, while neural networks are complicated and prone to in-sample overfitting, linear regressions are highly dependent on the specification of the regression function. The present paper shows how combining linear regression forecasts can be used to circumvent all of these problems. The usefulness of the proposed combination approach is verified using both Monte Carlo simulation and an extensive application to air quality in Bogota, one of the largest and most polluted cities in Latin America. © 2014 Elsevier Ltd.
