Las dificultades de los gobiernos occidentales para mantener los Sistemas de Bienestar han promovido la privatización en la gestión de los servicios. Las organizaciones del Tercer Sector, en su papel como proveedoras de servicios, deben adaptarse a los cambios provocados por las demandas sociales y tratar de fomentar su participación en la configuración de los sistemas, pero siendo capaces de demostrar la eficiencia con la que desarrollan sus actividades. Ante este reto, los sistemas de gestión de la calidad ofrecen una oportunidad a las organizaciones del Tercer Sector, aunque por parte de las entidades que conforman el sector se mantienen ciertas reticencias sobre la validez del modelo a causa de su origen empresarial. Este trabajo de investigación tiene por objetivo el estudio de los procesos de implantación de un sistema de Gestión de la Calidad en las organizaciones del Tercer Sector Social. Para ello se llevó a cabo un análisis de casos múltiples, eligiendo cuatro organizaciones en diferentes estadios de implantación. El tratamiento de la información se realizó mediante el software de análisis cualitativo Atlas.ti y, para la evaluación de cada caso, se siguió el sistema de valoración del EFQM, analizando los diferentes elementos de los agentes facilitadores. Los principales resultados muestran la importancia de las alianzas, el enfoque en el usuario así como en las personas, los cuales son considerados como elementos clave para estas organizaciones. El trabajo muestra las conclusiones para cuatro casos, pero sugiere la importancia de establecer las relaciones entre los agentes facilitadores así como un análisis causal para futuras líneas de investigación.

Estimates of length at birth and early postnatal growth are made for the northern and southern populations of the offshore spotted dolphin in the offshore eastern tropical Pacific. Length at birth is estimated to be 85.4 cm for the northern population and 83.2 cm for the southern population. Analyses of series of monthly distributions of length revealed two cohorts born each year in the northern population, at least in the northern inshore part of its geographic range, but only one cohort born each year in the southern population. Growth curves fitted to the means of the monthly distributions of length gave estimates of length at 1 year of 126.2 and 132.6 cm and length at 2 years of 154.3 and 154.9 cm for the two cohorts in the northern population. and length at 1 year of 127.9 cm for the southern population. A growth curve fitted to lengths and ages (in dental growth layer groups) from the northern population gave estimates of lengths at 1 and 2 years of 123.0 and 143.0 cm, respectively.

The broad scale features in the horizontal, vertical, and seasonal distribution of phytoplankton chlorophyll a on the northeast U.S. continental shelf are described based on 57,088 measurements made during 78 oceanographic surveys from 1977 through 1988. Highest mean water column chlorophyll concentration (Chlw,) is usually observed in nearshore areas adjacent to the mouths of the estuaries in the Middle Atlantic Bight (MAB), over the shallow water on Georges Bank, and a small area sampled along the southeast edge of Nantucket Shoals. Lowest Chlw «0.125 ug l-1) is usually restricted to the most seaward stations sampled along the shelf-break and the central deep waters in the Gulf of Maine. There is at least a twofold seasonal variation in phytoplankton biomass in all areas, with highest phytoplankton concentrations (m3) and highest integrated standing stocks (m2) occurring during the winter-spring (WS) bloom, and the lowest during summer, when vertical density stratification is maximal. In most regions, a secondary phytoplankton biomass pulse is evident during convective destratification in fall, usually in October. Fall bloom in some areas of Georges Bank approaches the magnitude of the WS-bloom, but Georges Bank and Middle Atlantic Bight fall blooms are clearly subordinate to WS-blooms. Measurements of chlorophyll in two size-fractions of the phytoplankton, netplankton (>20 um) and nanoplankton «20 um), revealed that the smaller nanoplankton are responsible for most of the phytoplankton biomass on the northeast U.S. shelf. Netplankton tend to be more abundant in nearshore areas of the MAB and shallow water on Georges Bank, where chlorophyll a is usually high; nanoplankton dominate deeper water at the shelf-break and deep water in the Gulf of Maine, where Chlw is usually low. As a general rule, the percent of phytoplankton in the netplankton size-fraction increases with increasing depth below surface and decreases proceeding offshore. There are distinct seasonal and regional patterns in the vertical distribution of chlorophyll a and percent netplankton, as revealed in composite vertical profiles of chlorophyll a constructed for 11 layers of the water column. Subsurface chlorophyll a maxima are ubiquitous during summer in stratified water. Chlorophyll a in the subsurface maximum layer is generally 2-8 times the concentration in the overlying and underlying water and approaches 50 to 75% of the levels observed in surface water during WS-bloom. The distribution of the ratio of the subsurface maximum chlorophyll a to surface chlorophyll a (SSR) during summer parallels the shelfwide pattern for stability, indexed as the difference in density (sigma-t) between 40 m and surface (stability 40. The weakest stability and lowest SSR's are found in shallow tidally-mixed water on Georges Bank; the greatest stability and highest SSR's (8-12:1) are along the mid and outer MAB shelf, over the winter residual water known as the "cold band." On Georges Bank, the distribution of SSR and the stability40 are roughly congruent with the pattern for maximum surface tidal current velocity, with values above 50 cms-1 defining SSR's less than 2:1 and the well-mixed area. Physical factors (bathymetry, vertical mixing by strong tidal currents, and seasonal and regional differences in the intensity and duration of vertical stratification) appear to explain much of the variability in phytoplankton chlorophyll a throughout this ecosystem.

The Alaska Fisheries Science Center (AFSC), National Marine Fisheries Service (NMFS), hosted an international workshop, 'The Importance of Prerecruit Walleye Pollock to the Bering Sea and North Pacific Ecosystems," from 28 to 30 October 1993. This workshop was held in conjunction with the annual International North Pacific Marine Science Organization (PICES) meeting held in Seattle. Nearly 100 representatives from government agencies, universities, and the fishing industry in Canada, Japan, the People's Republic of China, Russia, and the United States took part in the workshop to review and discuss current knowledge on juvenile pollock from the postlarval period to the time they recruit to the fisheries. In addition to its importance to humans as a major commercial species, pollock also serves as a major forage species for many marine fishes, birds, and mammals in the North Pacific region.

[ES] En este artículo se exponen los resultados obtenidos en una investigación descriptiva sobre la feminización del ámbito lector en la Literatura Infantil y Juvenil (LIJ) vasca. La tesis que desde el principio sostuvo esta investigación se fundamentó en que el progresivo aumento de la presencia de la mujer en el sistema literario vasco tendría que reflejarse también de alguna manera en el ámbito lector. Se utilizó el cuestionario como instrumento metodológico y se eligió una población escolar de 300 niños y niñas de edades comprendidas entre los 11 y 12 años en Vitoria. Se verificó la hipótesis preliminar; no obstante, se detectó una tendencia clara a una mayor presencia femenina en las lecturas de las niñas que en la de los niños. Las lectoras leen un mundo imaginario en un 21.6% más femenino que los lectores.

Zebrafish (Danio rerio) embryos have been used to quantify the teratogenic potential of environmental samples and harmful substances respectively. The short spawning interval renders this species a good test organism in toxicological research. Due to the transparency of the eggs several lethal and non-lethal endpoints can be detected in parallel after 48 h of embryonic development. Zebrafishembryos have been shown to be sensitive to a number of environmental relevant contaminants, as well as to ex-tracts from polluted sediments

The spring session of ACFM gave advice for a number of stocks in the North Atlantic, North Sea and Baltic. The present assessment of the situation is given here for stocks of higher importance for the German fishery. These are: Blue Whiting: the stock is still relatively high, this, however, will not last very long, due to too intense fishing. Cod in Kattegat: stock is outside safe biological limits. No immediate recovery in sight. Cod in 22–24 (Baltic): stock is inside save biological limits. F, however, is above the recommendation of the IBSFC. Greenland Halibut: state of the stock not quite clear. The present fishing intensity seems to be sustainable. Herring (Atlanto- scandian, Norwegian spring spawner): stock is within safe biological limits, weak recruitment of the recent years will lead to a reduction of biomass. Herring: for Baltic spring spawner in 22–24 and IIIa still no increasing tendency detectable. North Sea Herring: further increasing tendency, with 900 000 t over B lim, good recruitment. Herring in VIa: stable. Redfish: generally decreasing tendency observed, a reduction of the fishery is recommended. Signs of recovery, however, visible for some units

(ES) En el presente artículo trata de poner de relieve los mecanismos utilizados por Aristófanes en Lisístrata para presentar de forma paródica el sacrificio juratorio con el que las mujeres sellan el pacto para obligar a sus maridos a que firmen la paz. Se analiza en este trabajo la utilización del vocabulario específico y la organización básica de este ritual, que Aristófanes conserva intacto, en contraste con la sustitución operada en cuanto a la persona que realiza el sacrificio y a la víctima sacrificial, una jarra de vino de Tasos. Esta elección entronca con el motivo cómico del amor de las mujeres al vino, al que se dedica la segunda parte de este trabajo.
