The Cyclisation of l-Aryl-2-Benzamidoalkan-l-Ols to 4,5-DihydroOxazoles or Isoquinolines

The cyclisation of several N-benzoyl derivatives of 2-amino-l-phenylpropan-l-ol w~e carried out employing the Pictet-Cams modification ofthe BischlerNapieralski reaction. The formation of4, 5-dihydro-oxazoles orisoquinolines depends on the substituents on the N-benzoyl group. The mode of formation of the products is discussed

Detecting and mapping the ‘ephemeral’: magnetometric survey of a Pastoral Neolithic settlement at Luxmanda, Tanzania

Common assumptions about the ephemeral archaeological signature of pastoralist settlements have limited the application of geophysical techniques in the investigation of past herding societies. Here, the authors present a geophysical survey of Luxmanda, Tanzania, the largest-known settlement documented for the Pastoral Neolithic era in eastern Africa (c. 5000–1200 BP). The results demonstrate the value and potential of fluxgate gradiometry for the identification of magnetic anomalies relating to archaeological features, at a category of site where evidence for habitation was long thought to be undetectable. The study provides comparative data to enable archaeologists to identify loci for future investigations of mobile populations in eastern Africa and elsewhere

Pastoral Neolithic Settlement at Luxmanda, Tanzania

The later Holocene spread of pastoralism throughout eastern Africa profoundly changed socio-economic and natural landscapes. During the Pastoral Neolithic (ca. 5000–1200 B.P.), herders spread through southern Kenya and northern Tanzania—areas previously occupied only by hunter-gatherers—eventually developing the specialized forms of pastoralism that remain vital in this region today. Research on ancient pastoralism has been primarily restricted to rockshelters and special purpose sites. This paper presents results of surveys and excavations at Luxmanda, an open-air habitation site located farther south in Tanzania, and occupied many centuries earlier, than previously expected based upon prior models for the spread of herding. Technological and subsistence patterns demonstrate ties to northerly sites, suggesting that Luxmanda formed part of a network of early herders. The site is thus unlikely to stand alone, and further surveys are recommended to better understand the spread of herding into the region, and ultimately to southern Africa

Una Visión General del Sistema Financiero Colombiano

Desde finales de los 80 el sistema financiero colombiano ha experimentado cambios sensibles. En efecto, la liberalización financiera, el fortalecimiento de la regulación prudencial, la conversión de un número importante de sociedades en establecimientos de crédito, el aumento en los requisitos de capital, etc. han determinado un cambio de perfil en el sistema. Adicionalmente, en el pasado reciente las autoridades han tomado medidas en cuanto a la estructura de los encajes, aumentos en los requisitos de capital, el acceso al crédito externo, etc. que afectan de manera importante a las entidades financieras. A raíz de estas medidas ha surgido un debate acerca del tipo de sistema financiero que resulta más deseable para Colombia. La discusión es de vital importancia puesto que la estructura de encajes, las formas de intervención del Banco de la República en los mercados cambiario y monetario, la supervisión y todo el aparato regulatorio deben ser consistentes con el tipo de sistema que se desee. Con el fin de contribuir al debate, en este documento se presenta una breve descripción del estado actual del sistema financiero y su evolución reciente, se plantea una reflexión normativa acerca del tipo de sistema financiero que puede resultar más deseable y, finalmente,se presentan algunas recomendaciones.
