The hierarchical structures of the NEO-PI-R and the 16PF5

The present study compares the higher-level dimensions and the hierarchical structures of the fifth edition of the 16 PF with those of the NEO PI-R. Both inventories measure personality according to five higher-level dimensions. These inventories were however constructed according to different methods (bottom-up vs. top-down). 386 participants filled out both questionnaires. Correlations, regressions and canonical correlations made it possible to compare the inventories. As expected they roughly measure the same aspects of personality. There is a coherent association among four of the five dimensions measured in the tests. However Agreeableness, the remaining dimension in the NEO PI-R, is not represented in the 16 PF 5. Our analyses confirmed the hierarchical structures of both instruments, but this confirmation was more complete in the case of the NEO PI-R. Indeed, a parallel analysis indicated that a four-factor solution should be considered in the case of the 16 PF 5. On the other hand, the NEO PI-R's five-factor solution was confirmed. The top-down construction of this instrument seems to make for a more legible structure. Of the two five-dimension constructs, the NEO PI-R thus seems the more reliable. This confirms the relevance of the Five Factor Model of personality.

Comparison of the NEO-FFI, the NEO-FFI-R and an alternative short version of the NEO-PI-R (NEO-60) in Swiss and Spanish samples

Three different short versions of the NEO-PI-R were compared: The NEO-FFI, the NEO-FFI-R, and a new short version developed in the current study (NEO-60). This new version is intended to improve the psychometric characteristics of the original NEO-FFI, specially in regard to the factor structure at the item-level. A French version of the NEO-PI-R was given to 1090 Swiss subjects, whereas the Spanish (Castilian) version of the NEO-PI-R was administered to 1006 Spanish subjects. Results replicate the limitations of the NEO-FFI already found in other countries. Compared to the NEO-FFI, reliability coefficients and factor structure was enhanced by the NEO-FFI-R and the NEO-60 in both samples, although substantial differences were not found. The factor structure of the NEO-60 shows the best fit since only three items do not load mainly on their own factor in both samples. Besides, correlations between items and NEO-PI-R domain scores are also higher for the items included in the NEO-60 version. On the other hand, convergent correlations with the NEO-PI-R dimensions were satisfactory irrespective of the version, and confirmatory factor analyses show slight differences among the different models generated after the three short versions.

The 16PF5 and the NEO-PI-R in Spanish and Swiss samples: A cross-cultural comparison

This study compared the Spanish (Castilian) and French versions of the 16PF5 and of the NEO-PI-R in Spanish and Swiss samples. The five-factor solution for the 16PF5 only seems clear for the Castilian version, but not for the French version. Indeed, the congruence coefficients for the Tough-Mindedness and the Self-Control dimensions are low. On the other hand, the five-factor solutions are highly similar for both countries concerning the NEO-PI-R, and the congruence coefficients are above .95 for all five dimensions. The low cross-cultural replicability for the 16PF5 makes it difficult to analyze the differences at the mean level for this inventory. For the NEO-PI-R, the differences are generally very small and globally account for 2.6% of the total variance. Spaniards seem to have slightly lower scores on Actions and slightly higher scores on Dutifulness. These differences could either be due to translation problems, sample selection, or cultural differences.

Controladores PI con acción de reset

El control automàtic exerceix un paper important en molts processos de la industria. Cada un dels sistemes de control requereix d’un controlador, la majoria dels quals són del tipus PI. L’objectiu d’aquest projecte es investigar tècniques que permetin superar les limitacions que tenen els controladors PI lineals. En la resposta d’un sistema de control es poden distingir dues tasques diferents: El seguiment a un canvi d’entrada o consigna correspon a la tasca de servo, mentre que el rebuig a pertorbacions correspon a la tasca de regulatori. Al típic esquema de control realimentat, aquestes dues tasques estan enfrontades, és a dir, una millora a la tasca de servo implica un empitjorament a la tasca de regulatori i a l’inversa. Això suposa un problema al rendiment del sistema, així com la necessitat d’establir un cert compromís entre les dues tasques. El que es pretén en aquest projecte es implementar senzilles regles de control no lineal amb la finalitat de millorar el rendiment del sistema i evitar la necessitat d’establir un compromís entre les dues tasques. Així, es pretén superar les limitacions que aquest té, obtenint controladors PI alternatius fàcilment sintetitzables.

Outcomes of patients on dual-boosted PI regimens : experience of the Swiss HIV cohort study

Rapport de SynthèseLa thérapie antirétrovirale a progressée de manière significative depuis te début de l'épidémie du syndrome d'immunodéficience acquise (SIDA). Durant les 20 dernières années, plusieurs combinaisons de traitements ont été utilisées avec succès menant à une réduction de la mortalité associée. Par contre, le traitement a aussi engendré des cas de résistances multiples avec comme résultat, le besoin d'utiliser plusieurs molécules en combinaison, et une augmentation des cas de toxicité. Une stratégie souvent employée fût la combinaison de deux molécules inhibitrices de la protéase en même temps en combinaison avec une troisième molécule, le ritonavir. (DBPI).La cohorte Suisse sur le VIH existe depuis 1987 et permet d'étudier de façon longitudinale les patients qui y sont inscrits. Pour ce travail de thèse, nous avons étudié les patients inscrits à la cohorte suisse de 1996 à 2007 qui ont reçu une combinaison DBPI.Pendant la période étudiée, un total de 405 patients ont reçu un traitement DBPI, dont 295 patients ont reçu le DBPI pour plus de 6 mois. La durée médiane du traitement était de 2.2 ans. Sur les 287 patients qui étaient en échec viral au début du traitement (défini comme HIV RNA>400 copies/ml), 64.1% ont réussi à supprimer la virémie et 54.4% ont eu une suppression dans les 24 semaines qui ont suivi le début de la thérapie. Les patients avaient reçu en moyenne 6 combinaisons de traitement différentes avant le début de la thérapie DBPi. Pour les patients qui ont arrêté le traitement DBPI, la cause principale de l'arrêt était due au souhait du patient (48.3%), à l'échec virologique (22.5%) et à la toxicité (15.8%). Les patients ayant reçu le traitement après 1999, ou ayant été traités avec une combinaison de Lopinavir-ritonvir/saquinavir ou lopinavir-ritonavir/atazanavir arrivaient à supprimer leur virémie plus souvent que ceux qui avaient reçu d'autres combinaisons.Cette étude constitue la plus grande étude publiée sur le sujet de l'utilisation des DBPI pour les patients à résistances multiples. Malgré le fait que c'est une étude observationnelle, nous pouvons attester que le taux de succès était de 64.4%, le taux de toxicité était relativement bas (15.8%) et que la plus part des patients ont toléré ces combinaisons, malgré le taux élevé d'effets secondaires souvent rapportés. En somme, cette approche pourrait être envisagée dans des situations ou les nouveaux traitements tels que les inhibiteurs de l'intégrase et du CCR5 ne sont pas encore disponibles.

Outcomes of patients on dual-boosted PI regimens: experience of the Swiss HIV cohort study.

Dual-boosted protease inhibitors (DBPI) are an option for salvage therapy for HIV-1 resistant patients. Patients receiving a DBPI in the Swiss HIV Cohort Study between January1996 and March 2007 were studied. Outcomes of interest were viral suppression at 24 weeks. 295 patients (72.5%) were on DBPI for over 6 months. The median duration was 2.2 years. Of 287 patients who had HIV-RNA >400 copies/ml at the start of the regimen, 184 (64.1%) were ever suppressed while on DBPI and 156 (54.4%) were suppressed within 24 weeks. The median time to suppression was 101 days (95% confidence interval 90-125 days). The median number of past regimens was 6 (IQR, 3-8). The main reasons for discontinuing the regimen were patient's wish (48.3%), treatment failure (22.5%), and toxicity (15.8%). Acquisition of HIV through intravenous drug use and the use of lopinavir in combination with saquinavir or atazanavir were associated with an increased likelihood of suppression within 6 months. Patients on DBPI are heavily treatment experienced. Viral suppression within 6 months was achieved in more than half of the patients. There may be a place for DBPI regimens in settings where more expensive alternates are not available.

Pi*-pi* bonding interactions generated by halogen oxidation of zirconium(IV) redox-active ligand complexes.

The new complex, [Zr(pda)2]n (1, pda2- = N,N'-bis(neo-pentyl)-ortho-phenylenediamide, n = 1 or 2), prepared by the reaction of 2 equiv of pdaLi2 with ZrCl4, reacts rapidly with halogen oxidants to afford the new product ZrX2(disq)2 (3, X = Cl, Br, I; disq- = N,N'-bis(neo-pentyl)-ortho-diiminosemiquinonate) in which each redox-active ligand has been oxidized by one electron. The oxidation products 3a-c have been structurally characterized and display an unusual parallel stacked arrangement of the disq- ligands in the solid state, with a separation of approximately 3 A. Density functional calculations show a bonding-type interaction between the SOMOs of the disq- ligands to form a unique HOMO while the antibonding linear combination forms a unique LUMO. This orbital configuration leads to a closed-shell-singlet ground-state electron configuration (S = 0). Temperature-dependent magnetism measurements indicate a low-lying triplet excited state at approximately 750 cm-1. In solution, 3a-c show strong disq--based absorption bands that are invariant across the halide series. Taken together these spectroscopic measurements provide experimental values for the one- and two-electron energies that characterize the pi-stacked bonding interaction between the two disq- ligands.

Características estruturais de ácidos húmicos isolados de solos com adição de resíduos orgânicos de origem urbana: composição elementar, análise de RMN 13C e Pi-CG/EM

Foram avaliadas as alterações nas características estruturais de ácidos húmicos (AH) decorrentes da adição de matéria orgânica de resíduos urbanos. Os AH foram extraídos da camada superficial (0-20 cm) de um Argissolo Vermelho-Amarelo (Seropédica, RJ) e de um Latossolo Vermelho Amarelo (Piraí, RJ), ambos tratados com o equivalente a 80 t ha-1 (em base seca) de composto de lixo urbano e lodo de estação de tratamento de esgotos. O tempo de incubação em laboratório foi de 24 semanas à temperatura ambiente e umidade mantida na capacidade de campo. Para caracterizar os AH, foram utilizadas a análise elementar, a ressonância magnética nuclear (RMN) de 13C e Pirólise acoplada à cromatografia gasosa e a espectrometria de massas (Pi-CG/EM). A análise de RMN 13C permitiu observar alterações na composição molecular dos AH de forma clara, principalmente, pelo aumento do teor de C mono e di oxigenados (δC 50-110) e pela diminuição dos teores de grupos CH2 e CH3 (δC 50-110). O aumento no teor de carboidratos evidencia a presença de estruturas mais lábeis nos AH com adição dos resíduos. Em adição, a técnica de Pi-CG/EM permitiu verificar diferenças qualitativas significativas nos compostos orgânicos, provenientes da fragmentação térmica dos AH com incorporação de novas estruturas, sobretudo da fração lipídica e de derivados de carboidratos (furanos), nas amostras de solos tratados com ambos os resíduos orgânicos. O uso em conjunto das técnicas analíticas de RMN 13C e de Pi-CG/EM foi eficiente para avaliar as mudanças na composição molecular de ácidos húmicos decorrentes da adição de resíduos orgânicos de origem urbana.
