In Spain both accounting practice and accounting research have been strongly influenced by accounting practices developed in the Englishspeaking world. This paper:1) Summarizes a seminal English paper, the 'Corporate Report', that identified the potential for accounting reports to serve a wide range of users.2) Identifies the ways in which English language accounting conceptual frameworks have paid lip service to a range of user needs, but in practice have excluded users other than investors and creditors.3) Argues that for Spain the ideas put forward in the Corporate Report have a particular relevance, and might usefully form the basis for a new research agenda.

During the 1990's studies of management accounting practices in Europe and in Latin America have given us data on 23 countries. In this paper we use this data to identify five distinct aspects of national management accounting culture being:1. The influence of regulations on official recommendations;2. The source of management accountants;3. Influence from one country to another;4. Variations in use of specific techniques;5. Variations in the objectives of the management accounting system.We then identify seven significant implications of the manager operating in the multinational environment.

Creative accounting is a growing issue of interest in Spain. In this article we argue that the concept true and fair view can limit or promote the use of creative accounting depending upon its interpretation. We review the range of meanings that true and fair view can take at an international level and compare the experience of the United Kingdom with the Australian one by analysing the use of true and fair view to limit creative accounting. Finally, we suggest lines of action to be considered by the Spanish accounting standards-setting institutions.

Recent research shows that financial reports are losing relevance. Mainly thisis due to the growing strategic importance of intangible assets in theperformance of a company. A possible solution is to modify accounting standardsso that statements include more self-generated intangible assets, taking intoaccount with their inherent risk and difficulty of valuation. We surveyed loanofficers who were asked to assess the credit-worthiness of a hypotheticalcompany. The only information given was a simplified version of financialstatements. Half the group got statements where research and development costshad been capitalized. The other half got statements in which these costs hadbeen treated as an expense. The findings show that capitalization wassignificantly more likely to attract a positive response to a loan request. Thepaper raises the question of whether accounting for intangibles might providemanagers with one more creative accounting technique and, in consequence, itsethical implications.

After the accounting scandals that have taken place mainly in the UnitedStates during the last years, some Spanish leading authorities havedefended the idea that this kind of accounting problems cannot happen inSpain. They argue that accounting regulation in Europe, and specificallyin Spain, make more difficult the use of creative accounting practices.The objective of this paper is to identify some evidence about thesituacion in Spain. The study tries to demonstrate that some accountingpractices of several of the companies quoted in the Spanish Stock Exchangecould be qualified as earnings management.To carry out this study, the authors have analysed the accounts of the 35companies included in the stock market index IBEX 35. This index iscalculated with the share prices variations of the most importantcompanies quoted in the Spanish Stock Exchange.

The synthesis of a photoreactive derivative of the human leukocyte antigen-A1 (HLA-A1)-restricted MAGE-1 peptide 161-169 (EADPTGHSY) is described. Using conventional automated solid-phase peptide synthesis, a photoreactive derivative of this peptide was synthesized by replacing histidine-167 with photo-reactive N-beta-4-azidosalicyloyl-L-2,3-diaminopropionic acid. The C-terminal tyrosine was incorporated as phosphotyrosine. This peptide derivative was radioiodinated in the presence of chloramine T. This iodination took place selectively at the photoreactive group, because the phosphate ester prevented tyrosine iodination. Following dephosphorylation with alkaline phosphatase and chromatographic purification, the radiolabeled peptide derivative was incubated with cells expressing HLA-A1 or other HLA molecules. Photoactivation resulted in efficient photoaffinity labeling of HLA-A1. Other HLA molecules or other cellular components were not detectably labeled. This labeling was inhibited by HLA-A1 but not by HLA-A2-binding peptides. This synthesis is generally applicable and can also be adapted to the synthesis of well-defined radiolabeled nonphotoreactive peptide derivatives.

From the year of its foundation, until the foundation of Revista deContabilidad in 1997, REFC has been the only referred accounting journalin Spain. Published by the Spanish Association for Accounting and BusinessAdministration (AECA), this journal is at the heart of the emergence ofa distinctly Spanish academic accounting community.Our study is based on:1. An analysis of 100 issues of REFC covering the period from 1985 to 1999.2. A questionnaire to Spanish accounting academics on their perceptionsand experience of the journal.Key points emerging from this study include:a) A move away from interest in accounting concepts and rules, as wellas accounting history, and towards positive accounting theory, the impactof accounting information on capital markets, and financial analysis.b) The emergence of a small number of universities as the driving forcein Spanish accounting research.c) Spanish academics rate REFC highly compared to other Spanish journalsfor publication status, as a support for research, and as a support forteaching. A number of English language journals are rated more highly forboth publication status and as a support for teaching.

'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.

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.

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.

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.
