| This paper presents (1) a conceptual framework for structural change when farms may be multiproduct or specialized and (2) an econometrics examination of causes of structural and total factor productivity (TFP) change for U.S. agriculture. Farm size, farm specialization, and part-time farming are the structural dimension emphasized, and they become potential channels to TFP change. Using state aggregate data starting in 1950, we conclude that input prices, public and private research, public extension, and government commodity programs have directly and indirectly caused change in U.S. farm structure and TFP. Our results suggest that changes in farm size, however, have been dominated by input price changes rather than by technology or government programs. |

| Los primeros especialistas en mamíferos o maztozoólogos en Chile fueron naturalistas (siglo XVIII y XIX). A principios del siglo XX sobresalieron el Dr. Federico Albert, el Dr. Angel Cabrera y el profesor Bernardino Quijada, entre otros. En 1943, aparece "Mammals of Chile", obra fundamental en la mastozoología chilena, del Dr.W. H. Osgood. Entre 1946 y 1958, destacaron los trabajos sobre mamíferos marinos de los Dres. Guillermo Mann, Carlos Oliver Schneider y Parmenio Yáñez Andrade, en Santiago, Concepción y Valparaíso, respectivamente. En 1958, llega a nuestro país el Dr. Robert Clarke, a la Estación de Biología Marina de Montemar, de la Universidad de Chile, contratado por la Comisión Permanente del Pacífico Sur, con el fin de asesorarla en el manejo y... |

| Morale and faculty development are closely related. The agricultural economics profession must decide what it is about. There is room to practice the principle of comparative advantage and allow a degree of specialization in teaching, extension, and research. To continue in the role of an applied discipline, there must also be an opportunity for the young professional to establish rapport with, and understanding of, the private sector and the policy-making arena. If that is to happen, there must be encouragement in the institutional setting and by faculty colleagues who respect the importance of investment in building rapport and in establishing credibility. If that environment is present, morale should be good and faculty development will occur. |

| The number of research papers (128 papers) on mycotoxins published by Brazilian researchers in 1991-2000 surpassed the total number (85 papers) published in the preceding three decades (1961-1990). Thirty percent of the papers surveyed mycotoxins in foods and feeds. AFs in peanut and peanut products continued to be alarming, and high incidence and levels of FBs in corn and corn products also appeared as a serious problem. Contamination with other toxins, such as ZEA, OTA and trichothecenes, was low. Occurrence of AFM1 in milk and dairy products and patulin in apple juice needs to be verified as the results are somewhat diverging. Work on analytical methods, mycological examination and toxic effects constituted 16, 13 and 13%, respectively, of the published... |

| The aim of this investigation is to enrich the knowledge about nutrigenetics, a scientifictechnologyc paradigm in nutritional sciences. This new knowledge implies the interaction between nutrition and human genetic polymorphisms. However, the development of nutrigenetics will only be successful if the consumer, who has an essential role in this field, perceives clear health benefits, and if industries see a high potential for the development and innovation of food or genetic products, and commercial applications could be profitable. However, in order to achieve significant advances, it will be necessary a extensive economic investment in genomic research. |
