Lapid, Ulrich, and Rammsayer (2008) reported that estimates of the difference limen (DL) from a two-alternative forced choice (2AFC) task are higher than those obtained from a reminder task. This article reanalyzes their data in order to correct an error in their estimates of the DL from 2AFC data. We also extend the psychometric functions fitted to data from both tasks to incorporate an extra parameter that has been shown to allow obtaining accurate estimates of the DL that are unaffected by lapses. Contrary to Lapid et al.'s conclusion, our reanalysis shows that DLs estimated with the 2AFC task are only minimally (and not always significantly) larger than those estimated with the reminder task. We also show that their data are contaminated by response bias, and that the small remaining difference between DLs estimated with 2AFC and reminder tasks can be reasonably attributed to the differential effects that response bias has in either task as they were defined in Lapid et al.'s experiments. Finally, we discuss a novel approach presented by Ulrich and Vorberg (2009) for fitting psychometric functions to 2AFC discrimination data.

We recently published an article (García-Pérez & Alcalá- Quintana, 2010) reanalyzing data presented by Lapid, Ulrich, and Rammsayer (2008) and discussing a theoretical argument developed by Ulrich and Vorberg (2009). The purpose of this note is to correct an error in our study that has some theoretical importance, although it does not affect the conclusion that was raised. The error lies in that asymptote parameters reflecting lapses or finger errors should not enter the constraint relating the psychometric functions that describe performance when the comparison stimulus in a two-alternative forced choice (2AFC) discrimination task is presented in the first or second interval.

Fadrique Álvarez de Toledo, que nació hacia 1460 y murió en 1531, lidera en Castilla el linaje de la casa de Alba en el tránsito de la Edad Media al Renacimiento. Primo carnal de Fernando el Católico, y colaborador íntimo de los Reyes, desarrolla una amplia labor de mecenazgo artístico y literario, de la cual son ejemplos relevantes los apoyos a poetas como Juan del Encina, Juan Boscán o Garcilaso de la Vega. A pesar de esta actividad, la crítica no se ha ocupado con detalle de este personaje por haberle eclipsado un tanto su nieto, el Gran Duque de Alba. Este artículo reproduce el inventario de la biblioteca de Don Fadrique (formado por los libros que fueron catalogados a su muerte), inédito hasta ahora y que nos muestra una rica biblioteca patrimonial de ciento ochenta y seis obras. Entre los libros religiosos encontramos biblias, tratados de oración y libros de horas; se hallan también algunos títulos indispensables de las tradiciones franciscana y dominica, que nos muestran a un personaje interesado en las nuevas corrientes devocionales de finales del siglo XV, en el escolasticismo y en las mujeres santas y visionarias del Medievo.

In questo lavoro di tesi si presenta il primo studio multi-scala e multi-frequenza focalizzato sul getto della radiogalassia IC1531 (z=0.026) con i satelliti Chandra, XMM-Newton e Fermi con l’obiettivo di tracciarne l’emissione alle alte energie; definire i processi radiativi responsabili dell’emissione osservata e stimare i principali parametri fisici del getto; stimare l’energetica del getto alle diverse scale. La sorgente è stata selezionata per la presenza di un getto esteso (≈5’’) osservato in radio e ai raggi X, inoltre, era riportata come possibile controparte della sorgente gamma 3FGLJ0009.6-3211 presente nel terzo catalogo Fermi (3FGL). La presenza di emissione ai raggi γ, confermata dal nostro studio, è importante per la modellizzazione della SED della regione nucleare. L’emissione X del nucleo è dominata da una componente ben riprodotta da una legge di potenza con indice spettrale Γ=2.2. L’analisi dell’emissione in banda gamma ha evidenziato una variabilità su scale di 5 giorni, dalla quale è stato possibile stimare le dimensioni delle regione emittente. Inoltre viene presentato lo studio della distribuzione spettrale dell’energia della regione nucleare di IC 1531 dalla banda radio ai raggi γ. I modelli ci permettono di determinare la natura dell’emissione gamma e stimare la potenza cinetica del getto a scale del su-pc. Gli osservabili sono stati utilizzati per ottenere le stime sui parametri del modello. La modellizzazione così ottenuta ha permesso di stimare i parametri fisici del getto e la potenza trasportata del getto a scale del sub-pc. Le stime a 151MHz suggerisco che il getto abbia basse velocita' (Γ≤7) e angolo di inclinazione rispetto alla linea di vista 10°<ϑ<20°; nel complesso, il trasporto di energia da parte del getto risulta efficiente. L’origine dell’emissione X del getto a grandi scale è consistente con un’emissione di sincrotrone, che conferma la classificazione di IC1531 come sorgente di bassa potenza MAGN.

ResumenEn este trabajo se hace un análisis desde la creación de la Diócesis de Nicaragua y Costa Rica (1531-1850) hasta que se divide en 1850, cuya organización se basó en las disposiciones del Patronato Real y los acuerdos del Concilio de Trento (1545). De igual manera, se estudia el papel de los obispos que estuvieron al frente de la dirección de la diócesis y también son objeto de investigación los conflictos internos, en especial los que ocurrieron con la provincia de Costa Rica.AbstractThis work sets forth an analysis made of the Nicaraguan and Costa Rican Diocese (1531-1850) from its creation up to its division in 1850. It was established based on the resolutions of the Royal Patronage (Patronato Real) and the accords of the Council of Trent (1545). Likewise, research is carried out on the role played by the bishops that geared the Diocese, as well as on the internal conflicts, especially those that occurred in the province of Costa Rica.

ResumenEl artículo analiza las funciones del cabildo catedralicio de la Diócesis de Nicaragua y Costa Rica con el fin de explicar las relaciones sociales, políticas y económicas de sus miembros y determinar la importancia del cabildo en el funcionamiento de la diócesis entre los años 1531 y 1859. Las fuentes primarias coloniales sobre el cabildo catedralicio, los testamentos y padrones de diezmos, entre otros; revelan que los miembros del cabildo catedralicio de León tuvieron funciones específicas dentro de la diócesis tanto durante la sede vacante como cuando existía Obispo al frente de la diócesis. Los miembros del cabildo catedralicio no constituyeron un cuerpo capitular aislado de la sociedad, sino que mantuvieron relaciones de confianza, económicas y sociales entre ellos y con la sociedad que los rodeaba, por tanto, fueron un cuerpo capitular crucial para el funcionamiento de la diócesis durante su sede vacante y cuando fueron el consejo asesor del ObispoAbstractThe article analyzes the functions of the cathedral chapter of the Diocese of Nicaragua and Costa Rica with the purpose of explaining the social, political and economic relations of its members and determining the importance of the chapter in the operation of the diocese between the years 1531 and 1859. Colonial primary sources, including testaments and tithe registers, among others, reveal that the members of the cathedral chapter of Leon had specific functions within the diocese, both when the see was vacant and when there was a Bishop in office. The members of the cathedral chapter did not constitute a capitular body isolated from the rest of society. Rather, they maintained economic and social relations of trust among themselves and with the society that surrounded them. Therefore, they were a capitular body crucial to the operation of the diocese, both when they served as the bishops advisory committee and when they governed the diocese in the absence of a Bishop.
