La responsabilidad social corporativa en las empresas del IBEX-35

La responsabilitat social corporativa és un concepte molt genèric i, en moltes ocasions, bastant abstracte i desconegut que no significa que no estigui molt present i citat avui en dia. El treball de la responsabilitat social corporativa en les empreses de l’IBEX-35 té per objectiu ensenyar i educar al lector sobre què consisteix exactament aquest concepte i conèixer més profundament les raons per les quals és imprescindible incorporar-lo en el món empresarial, sota un context de globalització i de competència permanent. Tanmateix, una vegada interioritzat aquesta matèria és molt important per als clients, proveïdors i membres afectats per les activitats de l’empresa rebre la informació de forma detallada sobre quina metodologia, accions i missió que pren l’empresa per aconseguir complir amb els reptes i objectius que se li plantegen i es marca sobre RSC cosa que fa necessari per a assolir una bona conducta, coordinació i feed-back positiu entre l’empresa i els diferents grups d’interès una bona comunicació amb aquests grups d’interès. Això es possible gràcies a l’elaboració d’un informe de RSC. Per dur-lo a terme amb coherència, claredat i, sobretot, perquè pugui arribar a ser útil per a la gestió i govern de l’organització, serà necessari definir-lo i emmarcar-lo en els àmbits i temàtiques que té que contenir i el procediment per elaborar-lo. Tot informe precisa d’anàlisis per a avaluar la qualitat de la informació reflexada i, d’aquesta manera, poder realitzar accions correctores oportunes. Mitjançant la definició d’una sèrie d’indicadors de desenvolupament i altres, intentarem aproximar-nos a l’anàlisi dels continguts de les memòries de les empreses que componen l’IBEX-35 de l’any 2006, ja que podem considerar-les com les més representatives i més influents d’Espanya. Amb tot això sabrem quina és la situació en l’àmbit general dels informes que presenten aquestes empreses i podrem recomanar per a que les empreses puguin completar-lo i respondre més eficientment les necessitats dels futurs lectors d’aquest informe i obtenir millor imatge corporativa.

Clinical significance of the CCR5delta32 allele in hepatitis C.

BACKGROUND: The CCR5 receptor, expressed on Th1 cells, may influence clinical outcomes of HCV infection. We explored a possible link between a CCR5 32-base deletion (CCR5delta32), resulting in the expression of a non-functioning receptor, and clinical outcomes of HCV infection. METHODS: CCR5 and HCV-related phenotypes were analysed in 1,290 chronically infected patients and 160 patients with spontaneous clearance. RESULTS: Carriage of the CCR5delta32 allele was observed in 11% of spontaneous clearers compared to 17% of chronically infected patients (OR = 0.59, 95% CI interval 0.35-0.99, P = 0.047). Carriage of this allele also tended to be observed more frequently among patients with liver inflammation (19%) compared to those without inflammation (15%, OR = 1.38, 95% CI interval 0.99-1.95, P = 0.06). The CCR5delta32 was not associated with sustained virological response (P = 0.6), fibrosis stage (P = 0.8), or fibrosis progression rate (P = 0.4). CONCLUSIONS: The CCR5delta32 allele appears to be associated with a decreased rate of spontaneous HCV eradication, but not with hepatitis progression or response to antiviral therapy.

Adult abundance, biting behavior and parity of Anopheles aquasalis, Curry 1932 in two malarious areas of Sucre State, Venezuela

The principal vector of malaria in eastern Venezuela, Anopheles aquasalis, is exophagic and exophilic. Control using indoor insecticide house sprays has failed to lower the number of malaria cases. Therefore, studies were initiated in two villages of the eastern coastal state of Sucre to better understand this vector's biology and develop a more integrated control program. An. aquasalis was found to have a crepuscular biting behavior with a major peak at dusk and a minor peak at dawn. Mosquitos were collected more outdoors than indoors. Forty-seven percent of the biting took place before people went to bed (22:30 hr) and 69% of the mosquitos biting during this time period bite outdoors. Outdoor biting could be the reason why indoor spraying alone did not lower malaria cases. Seasonal abundance was greater in the rainy season compared to the dry season. Seasonal parous rates were high (78.3%-100%) and similar indoors and outdoors and between dry and wet season in Santa F e. In Guayana, the seasonal parity was lower (34.6%-42.2%) than Santa F e with indoor parity slightly higher than outdoors. Malaria cases were higher in Santa F e, but adult mosquito density was much lower than in Guayana. This difference could have been due to higher parity in Santa F e compared to Guayana. The greater distance to the nearest breeding site and presence of alternative hosts in Guayana can not be discounted as factors which contributed to the difference in malaria transmission between locations. We concluded that knowledge on seasonal occurrence, biting activity, resting behavior and breeding site location can be used to design a new control strategy for this vector.

Rhipidocotyle gibsoni n. sp. from a Brazilian Freshwater Fish and Rhipidocotyle froesi n.sp. for r. baculum (linton, 1905) of Eckmann (1932) (Bucephalidae; Digenea)

Rhipidocotyle gibsoni n.sp. is described from Acestrorhynchus lacustris from Paraná River, brazil. It is most closely related to r. froesi n. sp. and to R. eckmanni in the shape of the cephalic hood, differing in the extent of the uterus, in the position of the vitelline follicles and in that the host is a freshwater fish. Rhipidocotyle froesi n. sp. is proposed for the marine specimens described by Eckmann (1932) as R. baculum (Linton, 1905).

Présentation de l'adaptation française de « l'échelle de coparentage » de McHale pour familles avec jeunes enfants [Presentation of the french adaptation of McHale's coparenting scale for families with young children.]

The aim of this paper is to present McHale's coparenting scale,a self-administered questionnaire enabling assessment of the quality of coparenting, and first steps in structural and construct validation of the French version. A total of 41 French speaking Swiss families and 84 US families completed this questionnaire and the Dyadic Adjustment Scale, a measure of marital satisfaction. The results of the Swiss families correspond to those of US families: first, items distributed into four factors (family integrity, conflict, affection and disparagement) and second, a partial link was found between quality of coparenting and marital adjustment. This finding supports the construct validity of the questionnaire, reflecting the established link between these two family sub-systems. Given that coparenting quality has a major influence on children's socio-affective development, the questionnaire will find great use in assessing not just negative features of coparenting, such as conflicts and disparagement, but also positive components such as warmth and support. This will be an important asset for research as well as clinical purposes.

Bionomics of Anopheles aquasalis Curry 1932, in Guaraí, state of Rio de Janeiro, southeastern Brazil: I. Seasonal distribution and parity rates

From a total of 12,721 anophelines collected in a lowland area in Guaraí, Rio de Janeiro, from November 1991 to October 1992, 99.7% (12,688) were Anopheles aquasalis. This species occurred throughout the year, but in higher numbers from April to September, when rainfall was low or moderate. The proportion of parous females in June was significantly higher than the annual rate. An. aquasalis was weakly attracted by a light-trap, and no significant differences in abundance were detected between nights with and without moonlight.

Introduction de la quatrième édition française

L' »Ethique » de Bonhoeffer est un ouvrage marquant. Il l'est d'abord à cause de la personnalité de son auteur, résistant antinazi actif dans les complots contre Hitler, condamné et exécuté pour cela par les SS le 23 avril 1945. L' »Ethique » fait comprendre les raisons profondes de cet engagement au coeur du combat politique de l'époque et ce souci d'assumer de façon responsable ce que Bonhoeffer appelle les « réalités avant-dernières » du salut. Il y a plus: l' »Ethique » est devenu un classique de la réflexion éthique chrétienne qui prend au sérieux l'amour de Dieu en Christ pour le monde. Avec sa dimension incontestablement prophétique, Bonhoeffer donnait à cette réflexion la capacité d'entrevoir les défis que notre fin de siècle affronte. Dietrich Bonhoeffer est né en 1906 et mort, exécuté, le 8 avril 1945.

Birth records from Swiss married couples analyzed over of the past 35 years reveal an aging of first-time mothers by 5.1 years while the interpregnancy interval has shortened

RésuméIntroduction : Le travail de thèse est un article publié dans le journal « Fertility & Sterility » s'intitulant « Birth records from Swiss married couples analyzed over the past 35 years reveal an aging of first-time mothers by 5.1 years while the interpregnancy interval has shortened ».Méthodes : Les données concernant l'âge auquel les femmes mariées donnaient naissance ont été obtenues de l'Office fédéral de la statistique. Nous avons examiné la période allant de 1969 à 2006. Cet intervalle de temps choisi nous a permis de prendre en considération un total de 2'716'370 naissances. L'âge moyen des parturientes à la naissance de leur 1er, 2ème et 3ème enfant a été calculé pour chaque année à l'aide du logiciel Excel. Grâce à ces données on a pu obtenir les intervalles inter-gestationnels théoriques entre le 1er et 2ème enfant, ainsi qu'entre le 2ème et 3ème enfant.Résultats : Nous pouvons constater que l'intervalle inter-gestationnel théorique entre la première et la deuxième grossesse était de 23.2 mois en 1969 et passait à 13.0 mois en 2006. L'intervalle compris entre la deuxième et la troisième grossesse passait de 22.4 mois en 1969 à 7.9 mois en 2006. Notre analyse suggère donc que c'est le facteur social qui exerce un effet plus important que le facteur biologique sur les intervalles inter-gestationnels, car ces intervalles diminuaient malgré l'augmentation de l'âge des mères à la naissance.

Re-descriptions of Isospora ameivae Carini, 1932 in the Teiid Lizard Ameiva ameiva and Isospora hemidactyli Carini, 1936 in the Gecko Hemidactylus mabouia, with Particular Reference to their Endogenous Stages

Redescriptions are given of the mature oocysts of Isospora ameivae Carini, 1932, from the teiid lizard Ameiva ameiva, and Isospora hemidactyli Carini,1936 from the gecko Hemidactylus mabouia, in north Brazil. The endogenous stages of the two parasites in the small intestine are described. Those of I. ameivae are intracytoplasmic, whereas those of I. hemidactyli are intranuclear.

A 35.7 kb DNA fragment from the Bacillus subtilis chromosome containing a putative 12.3 kb operon involved in hexuronate catabolism and a perfectly symmetrical hypothetical catabolite-responsive element.

The Bacillus subtilis strain 168 chromosomal region extending from 109 degrees to 112 degrees has been sequenced. Among the 35 ORFs identified, cotT and rapA were the only genes that had been previously mapped and sequenced. Out of ten ORFs belonging to a single putative transcription unit, seven are probably involved in hexuronate catabolism. Their sequences are homologous to Escherichia coli genes exuT, uidB, uxaA, uxaB, uxaC, uxuA and uxuB, which are all required for the uptake of free D-glucuronate, D-galacturonate and beta-glucuronide, and their transformation into glyceraldehyde 3-phosphate and pyruvate via 2-keto-3-deoxygluconate. The remaining three ORFs encode two dehydrogenases and a transcriptional regulator. The operon is preceded by a putative catabolite-responsive element (CRE), located between a hypothetical promoter and the RBS of the first gene. This element, the longest and the only so far described that is fully symmetrical, consists of a 26 bp palindrome matching the theoretical B. subtilis CRE sequence. The remaining predicted amino acid sequences that share homologies with other proteins comprise: a cytochrome P-450, a glycosyltransferase, an ATP-binding cassette transporter, a protein similar to the formate dehydrogenase alpha-subunit (FdhA), protein similar to NADH dehydrogenases, and three homologues of polypeptides that have undefined functions.
