Abstract This paper introduces new estimates of recent productivity developments in the United States, using an appropriate theoretical framework for aggregating industry multi-factor productivity (MFP) to sectors and the total economy. Our work sheds light on the sources of the continued strong performance of US productivity since 2000.We find that the major sectoral players in the late 1990s pickup were not contributors to the more recent surge in productivity. Rather, striking gains in MFP in the finance and business service sector, a resurgence in MFP growth in the industrial sector, and an end to drops elsewhere more than account for the aggregate acceleration in productivity in recent years. Further, some evidence is found for a link between IT intensity and the recent productivity acceleration.

Este trabalho tem por objetivo analisar a produção recente no campo da história da legislação urbanística no Brasil, procurando detectar avanços e limites para a reflexão sobre desenvolvimento urbano e práticas urbanísticas. O texto organiza-se em três eixos analíticos. Em primeiro lugar, procura-se situar os trabalhos no processo de disseminação de estudos da história urbana no Brasil, vinculando-os ao movimento de ampliação do território da história que ocorre na Europa e nos Estados Unidos, a partir dos anos 60, com a chamada História Nova. Em segundo, baseado em um panorama da produção recente, são detectadas as vertentes dominantes e emergentes nos trabalhos sobre legislação. Em terceiro, são discutidos dois aspectos que se configuram como lacunas na historiografia da legislação: o lugar ocupado pelas normas, a partir do momento em que idéias e práticas urbanísticas têm um espaço institucionalizado na administração pública; e o lugar dos pressupostos modernistas na legislação brasileira, visto que o movimento modernista formula a proposta de um novo sistema legal para o urbanismo.Palavras-chave: legislação urbanística; história; movimento moderno. Abstract: This paper analyses recent developments in the history of Brazilian urban legislation, pointing out the progress made and limits faced, as a basis for reflection in the debate on urban development and planning practice. The analysis is divided into three parts. The first relates the dissemination of urban historical research in Brazil to the expansion of the field of history which began in the 1960s with the "New History" movement in Europe and the United States. The second part sets out the dominant and emerging approaches to urban legislation. Finally, there is a discussion of two aspects that are seen as gaps in the history of urban legislation: the role of norms, as the ideas and practices of urban planning become institutionalised within public administration, and the influences of modernist ideas on Brazilian urban legislation, taking into account that the modern movement proposes a new legal system for urban planning.Keywords: urban legislation; history; modernist movement.

Of particular concern, are the more recent developments that occurred due to technological advances, i.e. E-commerce, and rapid growth in Wal-Mart&rsquo;s operations. <span style="mso-spacerun: yes;">&nbsp;</span>It is noted that the industry has transitioned from a more competitive environment to an oligopolistic structure in which a few large firms dominate their respective market. The role of Wal-Mart is evaluated and its impact on the economy, in general, and in the retail industry, in particular, is elaborated upon.</span></span></p>

This study demonstrates the significance of individual difference factors, particularly gender and sensation seeking, in predicting media choice (examined through hypothetical descriptions of films that participants anticipated they would view). This study used a 2 (Positive mood/negative mood) × 2 (High arousal/low arousal) within-subject design with 544 undergraduate students recruited from a large northeastern university in the United States. Results showed that happy films and high arousal films were preferred over sad films and low-arousal films, respectively. In terms of gender differences, female viewers reported a greater preference than male viewers for happy-mood films. Also, male viewers reported a greater preference for high-arousal films compared to female viewers, and female viewers reported a greater preference for low-arousal films compared to male viewers. Finally, high sensation seekers reported a preference for high-arousal films. Implications for research design and importance of exploring media characteristics are discussed.
