Aptitude-based student selection: A study concerning the admission processes of some technically oriented healthcare degree programmes in Finland (Orthotics and Prosthetics, Dental Technology and Optometry). The data studied consisted of conveniencesamples of preadmission information and the results of the admission processes of three technically oriented healthcare degree programmes (Orthotics and Prosthetics, Dental Technology and Optometry) in Finland during the years 1977-1986 and 2003. The number of the subjects tested and interviewed in the first samples was 191, 615 and 606, and in the second 67, 64 and 89, respectively. The questions of the six studies were: I. How were different kinds of preadmission data related to each other? II. Which were the major determinants of the admission decisions? III. Did the graduated students and those who dropped out differ from each other? IV. Was it possible to predict how well students would perform in the programmes? V. How was the student selection executed in the year 2003? VI. Should clinical vs. statistical prediction or both be used? (Some remarks are presented on Meehl's argument: "Always, we might as well face it, the shadow of the statistician hovers in the background; always the actuary will have the final word.") The main results of the study were as follows: Ability tests, dexterity tests and judgements of personality traits (communication skills, initiative, stress tolerance and motivation) provided unique, non-redundant information about the applicants. Available demographic variables did not bias the judgements of personality traits. In all three programme settings, four-factor solutions (personality, reasoning, gender-technical and age-vocational with factor scores) could be extracted by the Maximum Likelihood method with graphical Varimax rotation. The personality factor dominated the final aptitude judgements and very strongly affected the selection decisions. There were no clear differences between graduated students and those who had dropped out in regard to the four factors. In addition, the factor scores did not predict how well the students performed in the programmes. Meehl's argument on the uncertainty of clinical prediction was supported by the results, which on the other hand did not provide any relevant data for rules on statistical prediction. No clear arguments for or against the aptitude-based student selection was presented. However, the structure of the aptitude measures and their impact on the admission process are now better known. The concept of "personal aptitude" is not necessarily included in the values and preferences of those in charge of organizing the schooling. Thus, obviously the most well-founded and cost-effective way to execute student selection is to rely on e.g. the grade point averages of the matriculation examination and/or written entrance exams. This procedure, according to the present study, would result in a student group which has a quite different makeup (60%) from the group selected on the basis of aptitude tests. For the recruiting organizations, instead, "personal aptitude" may be a matter of great importance. The employers, of course, decide on personnel selection. The psychologists, if consulted, are responsible for the proper use of psychological measures.

Con el objetivo de evaluar diferentes niveles de daños causados por enfermedades foliares en la etapa vegetativa de sorgo hibrido H 89-96 y su efecto en el rendimiento durante la época de postrera, se estableció este experimento en tierras que fueron alquiladas por el productor Agapito Ñurinda ubicada en el km 43 carretera Tipitapa Masaya, del departamento de Managua a 12° 08'36"de latitud norte y 86° 09' 49"de longitud oeste, Se utilizó un diseño con bloques completos al azar (BCA), Los tratamientos consistieron en aplicaciones de Benomyl con tres niveles de severidad de enfermedades; siendo el tratamiento uno con 3%, tratamiento dos con 7% tratamiento tres con 20% de severidad. El tratamiento T4 es el testigo al cual no se hizo aplicación alguna. Se realizaron aplicaciones calendarizadas para cogollero con Cypermetrina cada ocho días durante la etapa vegetativa y protección a la panoja con Cypermetrina y Benomyl al inicio de la floración para todos los tratamientos. La toma de datos para la severidad de enfermedades foliares fue basada en la escala de Takhur, utilizando cinco sitios al azar y registrando 10 plantas consecutivas por sitio. Los datos se procesaron mediante el análisis de varianza, para todas las variables evaluadas. No se presentaron condiciones climáticas favorables, para el desarrollo de las enfermedades que comúnmente afectan al cultivo del sorgo, no obstante la antracnosis (Colletotrichum graminicola (ces) G.W.Wison), se presentó en el híbrido de sorgo no alcanzado el 20 % de nivel de daño en estudio. El efecto de la aplicación de fungicida para antracnosis no mostró diferencia estadística entre tratamientos. La enfermedad no superó el 7% de severidad, durante la etapa vegetativa. Durante la etapa reproductiva, las condiciones ambientales favorecieron la incidencia de mohos en un período corto no mostrando diferencias estadísticas significativas. El acame se presentó hasta el momento de cosecha no llegando a tener significancia estadísticas en los tratamientos. Para la variable rendimiento el análisis de varianza no mostró diferencias significativas, sin embargo, los mayores rendimientos se obtuvieron en el T1 (3 % severidad) y T3 con 6 149, 01kg ha¹ y 5 389, 80kg ha¹ respectivamente. El análisis económico indicó que el T1 presentó mayor rentabilidad con un 0.55 %.

Anistia aos microempresários tumultua sessão e só de ser votada na próxima semana. A Zona Franca de Manaus será mantida por mais 25 anos. E ainda falta ser votada a maioria dos textos das disposições transitórias. Um dos temas é o problema dos atuais aposentados. Aproximadamente 14 milhões de aposentado de todo o país estão esperando o que será decidido pelos constituintes. Há várias emendas, como a do constituinte Valmir Campelo, que beneficiam as pessoas já aposentados. Já existe consenso sobre uma fusão de todas as emendas que concedem reajuste aos atuais aposentados, segundo o constituinte Farabulini Júnior. A sessão de ontem começou tumultuada. Havia a expectativa que fosse votada a anistia aos micro e pequenos empresárias. Mas a votação começou por outros temas. Foi aprovada a emenda garantindo a permanência da Zona Franca de Manaus por mais 25 anos, com suas características de área de livre comércio de importação e exportação. Foi aprovada a emenda que garante que a reforma tributária seja aplicada de forma progressiva. Na distribuição de recursos, os estados mais ricos serão igualados com os mais pobres. Em uma nova tentativa de acordo sobre a anistia dos microempresários, os líderes voltaram a se reunir com os autores da emenda da anistia. Mas não deu certo. Os autores da emenda queriam que a votação fosse ontem. Os líderes pediram o adiamento da votação que foi concedida pelo Deputado Ulysses Guimarães. Pretende-se que o texto da anistia seja votado hoje, mas a maioria dos constituintes acredita que a votação só será realizada na próxima semana.

The benthic macrofauna of the New York Bight has been monitored extensively, primarily to determine trends over space and time in biological effects of waste inputs. In the present study, from 44 to 48 stations were sampled each summer from 1980-1985. Data from other Bight benthic studies are included to· extend the temporal coverage from 1979 to 1989. Numbers of species and amphipods per sample, taken as relatively sensitive indicators of environmental stress, showed consistent spatial patterns. Lowest values were found in the Christiaensen Basin and other inshore areas, and numbers increased toward the outermost shelf and Hudson Shelf Valley stations. There were statistically significant decreases in species and amphipods at most stations from 1980 to 1985. (Preliminary data from a more recent study suggest numbers of species increased again between 1986 and 1989.) Cluster analysis of 1980-85 data indicated several distinct assemblages-sewage sludge dumpsite, sludge accumulation area, inner Shelf Valley, outer Shelf Valley, outer shelf-with little change over time. The "enriched" and "highly altered" assemblages in the Basin appear similar to those reported since sampling began there in 1968. No consistently defaunated areas have been found in any sampling programs over the past 20 years. On a gross level, therefore, recent faunal responses to any environmental changes are not evident, but the more sensitive measures used, i.e. numbers of species and amphipods, do indicate widespread recent effects. Causes of the faunal changes are not obvious; some possibilities, including increasing effects of sewage sludge or other waste inputs, natural factors, and sampling artifacts, are discussed.

The significance of detritus in the nutrition of aquatic animals, especially of the small representatives of the zooplankton, has been studied very slightly. Research so far has established that in M. rectirostris with feeding on protococcal and single-celled green algae and bacteria the beginning of formation of eggs takes place in 2 - 4 days. The young appear in 4 - 6 days. In this study M. rectirostris and C. quadrangula are fed on detritus of natural origin in laboratory conditions. In order to determine the assimilability and productive: effect of detritus, the author set up experiments, permitting to characterize the rate of growth, speed of maturing and fertility of M. rectirostris and C. quadrangula with feeding of them on detritus of different composition and age.

The consumption of oxygen in Asellus aquaticus was measured to find if there existed a periodicity in the consumption of oxygen and how this showed itself during the course of the day, year and in various experimental conditions. From the figures obtained comparative values were calculated and from these curves were plotted of the changes in the consumption of oxygen during the day and year.
