Estudio experimental de la efectividad de la entrevista abierta frente a la entrevista independiente de contexto
Resumen. OBJETIVO: Estudiar la efectividad relativa de las técnicas de entrevista abierta y entrevista independiente de contexto en la identificación de requisitos para sistemas software. MÉTODO: Experimento controlado ensayando dos factores: “tipo de entrevista” (abierta e independiente de contexto) y “tipo de problema” (identificación de requisitos para dos sistemas software distintos). Debid...
متن کاملPriests of Lucina: The Story of Obstetrics
of the process of growing old as it has been seen by twenty-four top-flight investigators. Each author presents the evidence from his own field of the slowing of physiological processes during the passage of time in all forms of life from plants, through protozoa and invertebrates, to mammals and man. Some attention is paid to personality and to psychological factors, as well as to the more obv...
متن کاملStructure and ligand selection of hemoglobin II from Lucina pectinata.
Lucina pectinata ctenidia harbor three heme proteins: sulfide-reactive hemoglobin I (HbI(Lp)) and the oxygen transporting hemoglobins II and III (HbII(Lp) and HbIII(Lp)) that remain unaffected by the presence of H(2)S. The mechanisms used by these three proteins for their function, including ligand control, remain unknown. The crystal structure of oxygen-bound HbII(Lp) shows a dimeric oxyHbII(L...
متن کاملExpression and purification of recombinant hemoglobin I from Lucina pectinata.
Hemoglobin I (HbI) from Lucina pectinata reacts with hydrogen sulfide to form the ferric sulfide complex needed to transport H2S to the bacterial endosymbiont. To further study HbI, expression studies of this protein were performed in Escherichia coli. This is the first time that the recombinant HbI was produced using a recombinant DNA expression system. Hemoglobin I cDNA was amplified and clon...
متن کاملRT patterns and chunks in SRT tasks: a reply to Jiménez (2008).
Previous research has shown that the formation of units or chunks contributes to sequence learning in serial reaction time (SRT) tasks (Koch & Hoffmann, Psychological Research 63:22-35, 2000). However, some of these results were assumed to be unrelated to sequence learning and to reflect preexistent response tendencies (Jiménez, Psychological Research 72:387-396, 2008). In the Experiment of thi...
