Mechanical control of floating aquatic weed: Kainji Lake experience

The paper describes the uniqueness and invasiveness of water hyacinth (Eichhornia crassipes) on Lake Kainji (Nigeria). The mechanical blocking device design concept based on the Kainji Lake flooding regime is also highlighted. Water hyacinth coverage, that was over 23% at high water in level in 1994, was reduced to 0.75% in the same period in 2000. Although this feat cannot be wholly ascribed to mechanical control effort alone, the first year of the device's full operation more than 1.04 million kg of fresh weight of water hyacinth were trapped, collected and deposited in two separate dumping pits, each at about 1 km off the shoreline of either side of the Lake. On further analysis over a period of one year of uncleared inflow of water hyacinth indicated the effectiveness of the bloom. Recommendations are advanced for the use of such local but highly technical knowledge to control floating water hyacinth that is vastly taking over the intricate network of Nigerian water systems and within the West African sub-region

Legal dimensions of the Chinese experience in Los Angeles, 1860-1880

On October 24, 1871, a massacre of eighteen Chinese in Los Angeles brought the small southern California settlement into the national spotlight. Within a few days, news of this “night of horrors” was reported in newspapers across the country. This massacre has been cited in Asian American narratives as the first documented outbreak of ethnic violence against a Chinese community in the United States. This is ironic because Los Angeles’ small population has generally placed it on the periphery in historical studies of the California anti-Chinese movement. Because the massacre predated Los Angeles’ organized Chinese exclusion movements of the late 1870s, it has often been erroneously dismissed as an aberration in the history of the city.

The violence of 1871 was an outburst highlighting existing community tensions that would become part of public debate by decade’s close. The purpose of this study is to insert the massacre into a broader context of anti-Chinese sentiments, legal discrimination, and dehumanization in nineteenth century Los Angeles. While a second incident of widespread anti-Chinese violence never occurred, brutal attacks directed at Chinese small businessmen and others highlighted continued community conflict. Similarly, economic rivalries and concerns over Chinese prostitution that underlay the 1871 massacre were manifest in later campaigns of economic discrimination and vice suppression that sought to minimize Chinese influence within municipal limits. An analysis of the massacre in terms of anti-Chinese legal, social and economic strategies in nineteenth-century Los Angeles will elucidate these important continuities.

Marketing experiencial aplicado a los establecimientos comerciales: Shopping experience

En el presente trabajo, se analiza el concepto de Marketing experiencial, aplicado a los establecimientos comerciales, lo que denominamos como Shopping Experience. Para ello, en primer lugar se explica el término teórico de Shopping Experience. A continuación se analiza el comportamiento del consumidor a lo largo de los últimos años, cómo han ido cambiando nuestros hábitos de compra y qué es lo que hacen los establecimientos comerciales para adaptarse a estas nuevas exigencias de los consumidores. Veremos nuevos modelos de establecimientos comerciales, donde se ofrece al cliente una experiencia memorable de compra y lo contrastaremos con ejemplos reales. Contamos con el testimonio de un ex – trabajador de Purificación García, donde hace una comparativa con la tienda de Carolina Herrera, y nos explica cuáles son las diferencias más significativas entre ambas, cómo son los diseños de las tiendas y qué papel juegan los sentidos a la hora de generar una experiencia de compra memorable. Finalmente veremos cómo los establecimientos comerciales pueden medir el impacto de estas experiencias en sus clientes y tras realizar un análisis teórico – práctico, se exponen las conclusiones del presente trabajo.
