ANÁLISIS PSICOMÉTRICO DEL "TEST DE FLUIDEZ DE DISEÑOS DE RUFF" EN POBLACIÓN UNIVERSITARIA DE BOGOTÁ
Executive function is the construct that comprises the spectrum of cognitive abilities that enable the individual to anticipate, initiate, provide feedback to the behavior and have cognitive flexibility. One of the useful tests to assess this function is the Ruff Figural Fluency Test which measures visuomotor programming and is associated with right frontal activity. In Colombia this test has not been validated with adult population, and considering the usefulness of this instrument for assessing people with neurological injury, the need to carry out a study to analyze the feasibility of using this test both in research and clinical practice was raised. The overall objective was to conduct a psychometric analysis of the Ruff Test with university population in Bogotá. The study was descriptive, of instrumental type. Participants were 492 university students, men and women, aged between 18 and 28 years, enrolled in seven universities of the city of Bogotá. The internal consistency analysis yielded a Cronbach's alpha of 0.876. In order to establish convergent validity, the WAIS cubes subtest was used, and a correlation of 0.24 was found, with p = 0.001. Factor analysis yielded four factors, three of which coincide with the studies conducted by the author of the test. The fourth factor found was related with following directions. Sex differences were found in the unique designs factor, where women obtained a higher average than men

Editorial: microbial communities and metabolisms involved in the degradation of cellular and extracellular organic biopolymers. Frontiers in Microbiology, 12, (2022): 802619, https://doi.org/10.3389/fmicb.2021.802619.Most organic matter on Earth occurs in the form of macromolecules and complex biopolymers, which include the building blocks of every organism. Plant, animal, fungal, and microbial cells largely consist of macromolecules belonging to four compound classes: proteins, polysaccharides, nucleic acids, and lipids (Figure 1). The percentage of these compounds per dry weight can vary greatly between lineages, but also between individuals of the same species or developmental stages of the same organism. Living and lysing cells release a substantial quantity and variety of macromolecules to the environment. These compounds often contain nitrogen, phosphorus, and sulfur, in addition to carbon, and are thus ideal food sources for heterotrophic organisms. Although the degradation of biopolymers and macromolecules has received considerable attention, many knowledge gaps remain, particularly in very complex ecosystems such as soils and sediments

Impeachment trial of U.S. President Bill Clinton. Day 16, afternoon session
During the afternoon session on the sixteenth day of the impeachment trial of President Bill Clinton, Chief Justice William Rehnquist questions Clinton's defense attorneys and members of the House Judiciary Committee who are serving as "managers", the equivalent of prosecutors. The questions, which are provided by Senators and simply read by Rehnquist, focus on the nature of the arguments made by the Managers and Clinton's attorneys. Clinton's attorneys Charles Ruff, David Kendall and Greg Craig defend their original arguments against conviction under Republican questioning. House Managers Henry Hyde (R-IL), Ed Bryant (R-TN), Bill McCollum (R-FL), Steve Buyer (R-IN), Asa Hutchinson II (R-AR), Bob Barr Jr. (R-GA) and Charles T. Canady (R-FL) defend their arguments for conviction under Democratic questioning. Part four of four

A análise de consistência interna mostrou um alfa de Cronbach de 0.876. Utilizou-se o sub-teste de cubos do WAIS para estabelecer a validade convergente, e encontrou-se uma correlação de 0.24, com um valor p = 0.001. A análise fatorial mostrou 4 fatores, três dos quais coincidem com os estudos realizados pelo autor do teste; o quarto fator encontrado relacionou-se com o seguimento de instruções. Encontraram-se diferenças por sexo no fator desenhos únicos, no qual as mulheres obtiveram uma média mais alta que os homens.La función ejecutiva es el constructo que reúne el conjunto de habilidades cognoscitivas que permiten anticipar, iniciar, retroalimentar el comportamiento y tener flexibilidad cognoscitiva.
