The ethics of creative accounting: Some Spanish evidence

'Creative accounting' involves accountants in making accounting policy choices or manipulating transactions in such a way as to give the impression in the accounts that they prefer. While regarded as unethical by most observers, a defence of creative accounting can be based on the ability of the users of accounts to identify bias in accounting policy choices and make appropriate adjustments.In this paper we take the example of the Barcelona Football Club where the club management made three key accounting policy choices that presented a favourable position, and a supporters' club presented an alternative report choosing three alternative accounting policies that presented an unfavourable position. We presented each of these financial reports to one of two groups of Spanish bank loan offices, with supporting notes making the impact of the accounting policy choices clear. We found that the more favourable set of accounts was significantly more likely to attract a positive response to a loan request.This result undermines the defence for creative accounting, based on the ability of users to identify manipulation.

Management control in non-profit organizations: The case of the Associations of Economists in Spain

The number of non-profit organizations has grown considerably over thelast decades, however management control techniques are not being introducedwith the same frequency as in lucrative organizations. The increasedcompetition in this sector has created a growing interest in managementcontrol techniques but with little empirical research in the area. Withthe aim to throw some light over the uses of management control inprofessional associations we have focused in the associations foreconomists in Spain as a particular case of a non-lucrative body.Specifically, the paper comprises three surveys addressed to the followingsectors:1) To the 30 Spanish associations of economists.2) To associations related to the business and/or economics area operatingin the United Kingdom.3) To members of the association of economists in Catalonia (Col.legid'Economistes de Catalunya).Results indicate that management accounting tools are used exceptionally,many times only the minimum legal requirements. The critical situation ofthe associations of economists in Spain requires the implementation ofinformation systems, specially taking into account the differentspecialities of economists and offering to its members, services and productsthat are not available through profit organizations.

OCORRÊNCIA E DIVERSIDADE DE GENES pspA ENTRE AMOSTRAS DE Streptococcus pneumoniae PERTENCENTES A COMPLEXOS CLONAIS CIRCULANTES NO BRASIL

De PINA, Sandrine Ester da Cruz Monteiro. Ocorrência e diversidade de genes pspA entre amostras de Streptococcus pneumoniae pertencentes a complexos clonais circulantes no Brasil. Rio de Janeiro, 2015. Dissertação (Mestrado em Ciências Biológicas - Microbiologia), Instituto de Microbiologia Paulo de Góes, Universidade Federal do Rio de Janeiro, Rio de Janeiro, 2015. Streptococcus pneumoniae é um importante patógeno associado a infecções invasivas, sendo também geralmente encontrado na nasofaringe de portadores assintomáticos. A cápsula polissacarídica é o principal fator de virulência e constitui a base das vacinas atualmente licenciadas. Devido às limitações inerentes às vacinas existentes, proteínas desse microrganismo, como a proteína de superfície pneumocócica A (PspA), são consideradas alvos de grande interesse para a formulação de novas estratégias de prevenção. No entanto, devido à natureza polimórfica dos genes pspA, torna-se essencial o levantamento de dados sobre a distribuição desses genes entre as amostras de pneumococos circulantes em diferentes regiões geográficas. Desta forma, o presente estudo teve como objetivo analisar a ocorrência e a diversidade de genes pspA entre 413 amostras de S. pneumoniae isoladas no Brasil entre 1988 e 2014, além de avaliar a ocorrência desses genes em amostras clínicas de espécies relacionadas (Streptococcus mitis e Streptococcus pseudopneumoniae), investigar a ocorrência de eventos de recombinação nesses genes e avaliar a distribuição de biomarcadores por MALDI-TOF MS em cada tipo de gene pspA. Todas as amostras de S. pneumoniae e apenas uma amostra de S. mitis albergavam genes pspA. Genes da família 2 (com destaque para a clade 3) foram os mais comuns (59,6%) com índices de ocorrência crescentes ao longo do tempo, seguidos dos genes da família 1 (39%; com destaque para a clade 1) e da família 3 (1,4%; todas clade 6). Dentro de uma mesma clade, as amostras compartilharam >80% de similaridade em fragmentos do gene pspA, sendo as clades pertencentes a uma mesma família mais próximas entre si evolutivamente. Os tipos de genes pspA foram conservados dentro de cada complexo clonal, independente de qualquer outra característica da amostra (como sorotipo, origem clínica e perfil de susceptibilidade à penicilina). Sinais de eventos de recombinação foram detectados, entre amostras de S. pneumoniae e S. mitis, em fragmentos do gene pspA que representam os alvos mais prováveis para inclusão em uma nova vacina baseada em PspA. MALDI-TOF MS apresentou potencial para ser utilizada como alternativa na caracterização dos diferentes tipos de genes pspA, distribuindo as amostras de S. pneumoniae em subgrupos que se correlacionaram com a família de genes pspA, e permitindo a determinação de perfis de biomarcadores de interesse representativos de cada clade. Este estudo adiciona dados ao conhecimento da distribuição das famílias e clades de genes pspA entre as amostras de pneumococos circulantes em nosso meio, sendo este aspecto de extrema importância para a elucidação da epidemiologia desta espécie bacteriana, assim como representa um passo essencial no desenvolvimento de novas estratégias vacinais.

Hipoglucèmia neonatal en fills de mares que han presentat diabetis gestacional

La hipoglucèmia neonatal (HN) és un problema de salut freqüent en les primeres hores de vida del recent nascut (RN) especialment de mares que pateixen diabetis mellitus (DM) durant l’embaràs, més coneguda com a diabetis gestacional (DG). La diabetis gestacional és un dels principals factors de risc que condiciona a un nadó a presentar hipoglucèmia en les hores posteriors al naixement, per això, els professionals d’infermeria necessiten conèixer la millor manera d’atendre a la dona embarassada que pateix DG amb l’objectiu d’ensenyar-li unes cures personals especifiques per intentar disminuir la incidència de recent nascuts (RN) que presenten hipoglucèmia.

Nitric oxide reduces Cl- absorption in the mouse cortical collecting duct through an ENaC-dependent mechanism.

Since nitric oxide (NO) participates in the renal regulation of blood pressure, in part, by modulating transport of Na(+) and Cl(-) in the kidney, we asked whether NO regulates net Cl(-) flux (JCl) in the cortical collecting duct (CCD) and determined the transporter(s) that mediate NO-sensitive Cl(-) absorption. Cl(-) absorption was measured in CCDs perfused in vitro that were taken from aldosterone-treated mice. Administration of an NO donor (10 μM MAHMA NONOate) reduced JCl and transepithelial voltage (VT) both in the presence or absence of angiotensin II. However, reducing endogenous NO production by inhibiting NO synthase (100 μM N(G)-nitro-l-arginine methyl ester) increased JCl only in the presence of angiotensin II, suggesting that angiotensin II stimulates NO synthase activity. To determine the transport process that mediates NO-sensitive changes in JCl, we examined the effect of NO on JCl following either genetic ablation or chemical inhibition of transporters in the CCD. Since the application of hydrochlorothiazide (100 μM) or bafilomycin (5 nM) to the perfusate or ablation of the gene encoding pendrin did not alter NO-sensitive JCl, NO modulates JCl independent of the Na(+)-dependent Cl(-)/HCO3(-) exchanger (NDCBE, Slc4a8), the A cell apical plasma membrane H(+)-ATPase and pendrin. In contrast, both total and NO-sensitive JCl and VT were abolished with application of an epithelial Na(+) channel (ENaC) inhibitor (3 μM benzamil) to the perfusate. We conclude that NO reduces Cl(-) absorption in the CCD through a mechanism that is ENaC-dependent.

Determinación de sistemas de flujo regionales y locales en las depresiones tectónicas del Baix Empordà y La Selva (NE de España) en base a datos hidroquímicos e isotópicos

The Baix Empordà-Selva-Gavarres aquifer system is related to the fault set that created the tectonic basins of Empordà and Selva areas (NE Spain) during the Neogene. In this work, we describe groundwater hydrogeological, hydrochemical and isotopical (3H, δD, δ18O, and the 87Sr/86Sr ratio) characteristics of this system in order to illustrate the relevance of fault zones in groundwater flow-paths and the recharge. In that way, we identify two flow systems, with distinct hydrochemistry and isotopes. A local flow system originates at the Gavarres Range, and it flows towards the basins of the Baix Empordà and Selva, with an approximate residence time of 20 years. Additionally, a regional flow system has only been identified in the Selva basin. This one is related to the main fault zones, as preferential flow paths. Its recharge is located in mountain ranges with higher altitudes, namely the Transversal and Guilleries Ranges, with residence times larger than 50 years. Isotopical data has also shown mixing processes between both flow systems and rainfall recharge while multivariate statistical analysis of principal components has shown the main processes that control hydrochemistry of each flow systems

Ventricular but not atrial electro-mechanical delay of the embryonic heart is altered by anoxia-reoxygenation and improved by nitric oxide.

BACKGROUND/AIM: Excitation-contraction coupling is modulated by nitric oxide (NO) which otherwise has either beneficial or detrimental effects on myocardial function during hypoxia-reoxygenation. This work aimed at characterizing the variations of electromechanical delay (EMD) induced by anoxia-reoxygenation within the developing heart and determining whether atrial and ventricular EMD are modulated by NO to the same extent. METHODS: Hearts of 4 or 4.5-day-old chick embryos were excised and submitted in vitro to normoxia (45 min), anoxia (30 min) and reoxygenation (60 min). Electrocardiogram and atrial and ventricular contractions were simultaneously recorded throughout experiment. Anoxia-reoxygenation-induced chrono-, dromo-and inotropic disturbances and changes in EMD in atrium (EMDa) and ventricle (EMDv) were investigated in control hearts and in hearts exposed to 0.1, 1, 10, 50 and 100 microM of DETA-NONOate (a NO donating agent) or to 50 microM of L-NAME (a NOS inhibitor). RESULTS: Under normoxia, heart rate, PR interval, ventricular shortening velocity, EMDa and EMDv were similar in control, L-NAME-treated and DETA-NONOate-treated hearts. Under anoxia, cardiac activity became markedly erratic within less than 10 min in all groups. At the onset of reoxygenation, EMDv was increased by about 300% with respect to the preanoxic value while EMDa did not vary significatively. Compared to control conditions, L-NAME or DETA-NONOate had no influence on the negative chrono-, dromo- and inotropic effects induced by anoxia-reoxygenation. However, L-NAME prolonged EMDv during anoxia and delayed EMDv recovery during reoxygenation while 100 microM DETA-NONOate had the opposite effects. EMDa was neither affected by NOS inhibitor nor NO donor. At the end of reoxygenation, all the investigated parameters returned to their basal values. CONCLUSION: This work provides evidence that a NO-dependent pathway is involved in regulation of the ventricular excitation-contraction coupling in the anoxic-reoxygenated developing heart.

Impacte d'un programa d'informació sobre l'elaboració del document de voluntats anticipades

Tot i que en el nostre territori comptem des de els anys 80 amb diferents models de Document de Voluntats Anticipades (DVA), aquests continuen essent desconeguts tant per la ciutadania com pels professionals de la salut. Aquesta situació ha fet que ens plantegem com a objectiu d’aquest estudi descriure si existeix la correlació entre el fet de proporcionar informació sobre el DVA i la motivació per la seva realització. En aquest estudi hem agafat com a mostra els usuaris del servei de psicogeriatria de la Fundació Sociosanitaria de Manresa l’Hospital de Sant Andreu de Manresa, tenint en compte les recomanacions del Document Sitges del 2005 i d’altres autors que recomanen fer el DVA en situació de demència lleu o moderada. També s’ha tingut present l’elevada prevalença d’aquesta patologia. S'ha dissenyat un assaig clínic comunitari amb aleatorització de dos consultoris d'un servei de psicogeriatria. Els metges del consultori assignat al grup control feien el tractament habitual en relació al DVA, és a dir, no informar els pacients atesos sobre l'existència i característiques del DVA, i els metges del consultori assignat al grup intervenció donaven informació reglada als seus pacients sobre el DVA. En el moment de la inclusió es registrava informació sociodemogràfica i clínica per poder classificar els participants i, també a tots els subjectes inclosos en l'assaig, al cap de tres setmanes se'ls feia una enquesta telefònica per avaluar l'opinió i el coneixement sobre el DVA. De les respostes de l’enquesta podem extreure com a resultats que més del 90% dels subjectes del grup control no coneixen el DVA. També s’observa de manera significativa com les persones del grup intervenció parlen amb el metge,la infermera i/o la família sobre la dependència i la mort, tenint en compte que la mort i la dependència continuen sent un tema tabú, i que la majoria de la població de l’estudi no planifiquen com volen ser atesos. Tanmateix s’observa com un 2’3 % tenia fet el DVA i un 22’7% manifesten la seva voluntat de realitzar-lo. Amb aquest estudi es conclou que el fet de proporcionar informació sobre el DVA als usuaris del servei de psicogeriatria afavoreix que aquests estiguin motivats per la realització d’aquest document; al mateix temps també afavoreix la planificació de les cures i el parlar sobres temes com la mort i/o la dependència amb la família, el metge la infermera.

Els plans municipals de biblioteques: contextualització i situació a Catalunya

S'analitzen les funcions de la biblioteca pública previstes en les darreres pautes internacionals sobre la biblioteca pública de l'IFLA/UNESCO. Es destaca que, per poder fer front als nous reptes, la biblioteca pública necessita treballar en una doble perspectiva: el treball en xarxa i el treball de cooperació en el territori. Es consideren els plans municipals de biblioteques com una eina que ha de vetllar per l'adequació del servei bibliotecari a l'entorn on desenvolupa els serveis i per garantir aquest treball necessari de cooperació en el territori i s'analitza la situació a Catalunya pel que fa a l'elaboració de plans municipals de biblioteques. El treball es clou amb una bibliografia temàtica.

Reduction of corneal edema in endotoxin-induced uveitis after application of L-NAME as nitric oxide synthase inhibitor in rats by iontophoresis.

PURPOSE: To investigate the involvement of the cornea during endotoxin-induced uveitis (EIU) in the rat and the effect of Ngamma-nitro-L-arginine methyl ester (L-NAME) as nitric oxide synthase (NOS) inhibitor, administered by iontophoresis. METHODS: EIU was induced in Lewis rats that were killed at 8 and 16 hours after lipopolysaccharide (LPS) injection. The severity of uveitis was evaluated clinically at 16 hours, and nitrite levels were evaluated in the aqueous humor at 8 hours. Corneal thickness was measured, 16 hours after LPS injection, on histologic sections using an image analyzer. Transmission electron microscopy (TEM) was used for fine analysis of the cornea. Transcorneoscleral iontophoresis of L-NAME (100 mM) was performed either at LPS injection or at 1 and 2 hours after LPS injection. RESULTS: At 16 hours after LPS injection, mean corneal thickness was 153.7+/-5.58 microm in the group of rats injected with LPS (n=8) compared with 126.89+/-11.11 microm in the saline-injected rats (n=8) (P < 0.01). TEM showed stromal edema and signs of damage in the endothelial and epithelial layers. In the group of rats treated by three successive iontophoreses of L-NAME (n=8), corneal thickness was 125.24+/-10.36 microm compared with 146.76+/-7.52 microm in the group of rats treated with iontophoresis of saline (n=8), (P=0.015). TEM observation showed a reduction of stromal edema and a normal endothelium. Nitrite levels in the aqueous humor were significantly reduced at 8 hours by L-NAME treatment (P=0.03). No effect on corneal edema was observed after a single iontophoresis of L-NAME at LPS injection (P=0.19). Iontophoresis of saline by itself induced no change in corneal thickness nor in TEM structure analysis compared with normal rats. CONCLUSIONS: Corneal edema is observed during EIU. This edema is significantly reduced by three successive iontophoreses of L-NAME, which partially inhibited the inflammation. A role of nitric oxide in the corneal endothelium functions may explain the antiedematous effect of L-NAME.
