Strategic responses to global challenges: The case of European banking, 1973–2000

In applying a strategy, structure, ownership and performance (SSOP) framework to three major clearing banks (ABN AMRO, UBS, Barclays), this article debates whether the conclusions generated by Whittington and Mayer about European manufacturing industry can be applied to the financial services sector. While European integration plays a key role in determining strategy, it is clear that global factors were far more important in determining management actions, leading to significant differences in structural adaptation. The article also debates whether this has led to improved performance, given the problems experienced with both geographical dispersion and diversification, bringing into question the quality of decision-making over the long term

Óleo essencial de alecrim no controle de doenças e na indução de resistência em videira

O objetivo deste trabalho foi determinar as características químicas do óleo essencial de alecrim e o seu efeito na produtividade, no controle da mancha da folha e do míldio, e na indução de resistência em videira 'Isabel'. O experimento foi realizado em vinhedo comercial, em dois ciclos consecutivos. Os tratamentos consistiram das doses do óleo essencial: 0, 500, 1.000, 2.000 e 4.000 µL L-1, além dos tratamentos Tween 80%, calda bordalesa, acibenzolar-S-metil e mancozebe. Foram avaliados a severidade da mancha da folha e do míldio, a atividade das enzimas quitinase e catalase, a massa e o número de cachos e as características químicas das uvas. Houve efeito quadrático das doses do óleo essencial de alecrim, para severidade da mancha da folha e do míldio da videira, nos dois ciclos, com resultados semelhantes aos dos tratamentos com calda bordalesa, acibenzolar-S-metil e mancozeb. Também houve aumento no número e na massa dos cachos, bem como na produtividade. O óleo essencial não interferiu nas características químicas das uvas. Observaram-se aumento na atividade da enzima quitinase e redução na atividade da catalase nas folhas. O óleo essencial nas doses de 500, 1.000 e 2.000 μL L-1 é uma alternativa para o controle de doenças da videira 'Isabel'

Defining the origin of Plasmodium falciparum resistant dhfr isolates in Senegal.

We previously reported a high baseline prevalence of mutations in the dhfr and dhps genes of Plasmodium falciparum throughout Senegal. The highest prevalence of the triple dhfr pyrimethamine associated mutations were found in isolates obtained in the western part of the country near the capital city of Dakar. In this study, we sought out to determine the relatedness of dhfr wild type and mutated strains by analyzing three microsatellite regions upstream of the dhfr locus. Twenty-six of the 31 wild type strains had a unique microsatellite pattern. In contrast, of the 17 isolates containing the triple mutation in dhfr, 11 had an identical microsatellite pattern. Diverse geographical isolates in Senegal containing the triple dhfr mutation have arisen from a limited number of ancestral strains. In addition, we demonstrate that these isolates have shared ancestry with the previously reported triple mutation haplotype found in Tanzania, South Africa, and southeast Asia. This common ancestry may have implications for the malaria control strategy for reducing the spread of sulfadoxine-pyrimethamine resistance in Senegal and elsewhere in Africa
