La familia de la Compuestas (=Asteraceae) es la más numerosa de todas las fanerógamas con aproximadamente 23000 especies y más de 1500 géneros ampliamente distribuidos en todos los continentes excepto en la Antártida. En la República Argentina es la familia más abundante con 222 géneros nativos y 1490 especies, en tanto que en la provincia de Buenos Aires, las compuestas representan la sexta parte de la flora de plantas vasculares con 113 géneros y 356 especies, de las cuales 55 son adventicias y el resto indígenas. Muchas de las especies de esta familia son utilizadas por el hombre como plantas alimenticias o medicinales. Algunas especies son tóxicas para el ganado. Otras son utilizadas como repelentes de insectos o son perjudiciales por ser malezas invasoras en los campos y competir con las plantas cultivadas.

[ES] El presente artículo pretende aportar nuevos datos sobre la ganadería en los territorios vascos durante la Edad Moderna. Ante todo se trata de romper con falsos paradigmas que se han venido repitiendo durante largo tiempo, aportando datos inéditos. Los clásicos de la historiografía vasca siempre han recalcado el carácter rural y agrario de la economía vasca; a pesar de ello, actividades como la ganadería jamás han ocupado un espacio primordial como objeto de estudio entre los historiadores, que en muchos casos han aceptado las teorías de etnógrafos y antropólogos sin contrastarlas. La ganadería en tierras vascas siguió modelos cantábricos, que ya vienen siendo estudiados desde algunas décadas por los historiadores gallegos, asturianos o cántabros; escuelas que han establecido nuevas metodologías para el estudio de la ganadería, las cabañas predominantes, el régimen de explotación, su impacto económico, etc., y cuyo ejemplo desgraciadamente no ha sido secundado en el caso vasco.

ENGLISH: Hitherto the only investigation dealing with the food and feeding of the larvae of the northern anchovy, Engraulis mordax Girard, was that of Arthur (1956). His main consideration was, however, with the Pacific sardine, Sardinops caerulea (Girard), and his work on the anchovy can only be considered preliminary. The present investigation is a continuation of Arthur's work on the food of the larval northern anchovy. SPANISH:El único trabajo publicado hasta ahora que trata sobre el alimento y nutrición de las larvas de la anchoa norteña, Engraulis mordax Girard, es el de Arthur (1956); pero su objeto principal fué la sardina del Pacifico, Sardinops caendea (Girard), y el estudio dedicado a la anchoa solo puede considerarse como preliminar. La presente investigación es una continuación del estudio de Arthur sobre el alimento de las larvas de la anchoa norteña.

[EN] The objective of this study was to determine whether a short training program, using real foods, would decreased their portion-size estimation errors after training. 90 student volunteers (20.18±0.44 y old) of the University of the Basque Country (Spain) were trained in observational techniques and tested in food-weight estimation during and after a 3-hour training period. The program included 57 commonly consumed foods that represent a variety of forms (125 different shapes). Estimates of food weight were compared with actual weights. Effectiveness of training was determined by examining change in the absolute percentage error for all observers and over all foods over time. Data were analyzed using SPSS vs. 13.0. The portion-size errors decreased after training for most of the foods. Additionally, the accuracy of their estimates clearly varies by food group and forms. Amorphous was the food type estimated least accurately both before and after training. Our findings suggest that future dietitians can be trained to estimate quantities by direct observation across a wide range of foods. However this training may have been too brief for participants to fully assimilate the application.

[EN] The objective of this study was to test the hypothesis that cooperative learning strategies will help to increase nutrition knowledge of nurses and nursing assistants caring for the elderly in different institutional communities of the Basque Country, Spain. The target population was a sample of volunteers, 16 nurses and 28 nursing assistants. Training consisted of 12 nutrition education sessions using cooperative strategies conducted over a period of 3 consecutive weeks. The assessment instruments included two pretest and two posttest questionnaires with questions selected in multiplechoice format. The first questionnaire was about general knowledge of applied nutrition (0-88 point scale) and the second one on geriatric nutrition knowledge (0-18 point scale). Data were analyzed using SPSS vs. 11.0. The outcomes indicated a significant increase in general nutrition knowledge (difference between the pre- and posttest mean score: 14.5±10.1; P<0.001) and in geriatric nutrition knowledge for all participants (difference between the pre- and post-test mean score: 4.6±4.6; P<0.001). So the results indicated that cooperative learning strategies could improve the nutrition knowledge of nursing staff. Additionally, the results of this study provide direction to continuing nutrition education program planners regarding appropriate content and methodology for programs.

[EN] Some authors have suggested that body weight dissatisfaction may be high in students majoring in dietetics. Therefore, this study was conducted to examine the extent of body weight and image dissatisfaction in a sample of women in dietetics major. Additionally, predictors of magnitude of body weight dissatisfaction were analyzed. Participants were 62 volunteers with normalweight whose mean age was 21.87±1.89 years old (nonrandom sample). The assessment instruments included anthropometric measurements, a somatomorphic matrix test and an eating disorders inventory (EDI-2). Data were analyzed using SPSS vs. 15.0. A larger proportion of students chose an ideal body weight lower than actual weight (67.7%) and body image with less body fat and more muscle mass than actual values (56.4%). The magnitude of body weight dissatisfaction was associated with muscle mass and body fat dissatisfaction, and with the subscale of EDI-2 “body dissatisfaction”. So, from a public health standpoint, we consider important to continue working in this line of research with the aim of better understanding the extent of body weight dissatisfaction in women dietitians, and how this dissatisfaction could interfere with their professional practice.
