Cost system design and cost management in the Spanish public sector

Cost systems have been shown to have developed considerably in recent years andactivity-based costing (ABC) has been shown to be a contribution to cost management,particularly in service businesses. The public sector is composed to a very great extentof service functions, yet considerably less has been reported of the use of ABC tosupport cost management in this sector.In Spain, cost systems are essential for city councils as they are obliged to calculate thecost of the services subject to taxation (eg. waste collection, etc). City councils musthave a cost system in place to calculate the cost of services, as they are legally requirednot to profit , from these services.This paper examines the development of systems to support cost management in theSpanish Public Sector. Through semi-structured interviews with 28 subjects within oneCity Council it contains a case study of cost management. The paper contains extractsfrom interviews and a number of factors are identified which contribute to thesuccessful development of the cost management system.Following the case study a number of other City Councils were identified where activity-based techniques had either failed or stalled. Based on the factors identified inthe single case study a further enquiry is reported. The paper includes a summary usingstatistical analysis which draws attention to change management, funding and politicalincentives as factors which had an influence on system success or failure.

Design Gráfico na Construção da Identidade visual da Marca Turística em City Branding.

Esta dissertação apresenta um estudo sobre a participação de Design Gráfico no projeto de identidade visual das marcas turísticas de cidades. O foco recai sobre a coerência da visualidade gráfica da marca com relação ao posicionamento socioeconômico e cultural das cidades, como instâncias de empreendimentos turísticos. O estudo do posicionamento das marcas de cidades foi baseado no livro Competitive Identity (ANHOLT, 2007), também, em Anholt city branding index (2006) e nas atualizações parciais desse índice (ANHOLT, 2009 e 2011). Além disso, as marcas gráficas de 30 cidades e os respectivos dados sobre seu posicionamento, como empreendimentos turísticos, foram coletadas em websites oficiais das cidades na internet. Tendo como base essas 30 cidades com um a marca gráfica turística da cidade, foi proposta uma classificação visual dessas baseando-se em três principais categorias: Categorização conceitual; a Categorização cinéticosensorial; Categorização visual. Com base nessas informações e na classificação da visualidade das marcas gráficas pesquisadas, foi realizado um estudo comparado, visando estabelecer coerências entre a comunicação visual da marca gráfica e o posicionamento socioeconômico e cultural das cidades turísticas. Diante disso, apresentam-se em destaque as marcas das cidades São Paulo e Melbourne, como um exemplo nacional e outro internacional da criatividade gráfica aplicada e da coerência entre o posicionamento do empreendimento turístico e a identidade visual da marca

Costly search and design

Firms compete by choosing both a price and a design from a family of designs thatcan be represented as demand rotations. Consumers engage in costly sequential searchamong firms. Each time a consumer pays a search cost he observes a new offering. Anoffering consists of a price quote and a new good, where goods might vary in the extentto which they are good matches for the consumer. In equilibrium, only two design-styles arise: either the most niche where consumers are likely to either love or loathethe product, or the broadest where consumers are likely to have similar valuations. Inequilibrium, different firms may simultaneously offer both design-styles. We performcomparative statics on the equilibrium and show that a fall in search costs can lead tohigher industry prices and profits and lower consumer surplus. Our analysis is relatedto discussions of how the internet has led to the prevalence of niche goods and the"long tail" phenomenon.

The minimax distortion redundancy in empirical quantizer design

We obtain minimax lower and upper bounds for the expected distortionredundancy of empirically designed vector quantizers. We show that the meansquared distortion of a vector quantizer designed from $n$ i.i.d. datapoints using any design algorithm is at least $\Omega (n^{-1/2})$ awayfrom the optimal distortion for some distribution on a bounded subset of${\cal R}^d$. Together with existing upper bounds this result shows thatthe minimax distortion redundancy for empirical quantizer design, as afunction of the size of the training data, is asymptotically on the orderof $n^{1/2}$. We also derive a new upper bound for the performance of theempirically optimal quantizer.

The challenge of representative design in psychology and economics

The demands of representative design, as formulated by Egon Brunswik (1956), set a high methodological standard. Both experimental participants and the situations with which they are faced should be representative of the populations to which researchers claim to generalize results. Failure to observe the latter has led to notable experimental failures in psychology from which economics could learn. It also raises questions about the meaning of testing economic theories in abstract environments. Logically, abstract tests can only be generalized to abstract realities and these may or may not have anything to do with the empirical realities experienced by economic actors.

Expanding molecular modeling and design tools to non-natural sidechains.

Protein-protein interactions encode the wiring diagram of cellular signaling pathways and their deregulations underlie a variety of diseases, such as cancer. Inhibiting protein-protein interactions with peptide derivatives is a promising way to develop new biological and therapeutic tools. Here, we develop a general framework to computationally handle hundreds of non-natural amino acid sidechains and predict the effect of inserting them into peptides or proteins. We first generate all structural files (pdb and mol2), as well as parameters and topologies for standard molecular mechanics software (CHARMM and Gromacs). Accurate predictions of rotamer probabilities are provided using a novel combined knowledge and physics based strategy. Non-natural sidechains are useful to increase peptide ligand binding affinity. Our results obtained on non-natural mutants of a BCL9 peptide targeting beta-catenin show very good correlation between predicted and experimental binding free-energies, indicating that such predictions can be used to design new inhibitors. Data generated in this work, as well as PyMOL and UCSF Chimera plug-ins for user-friendly visualization of non-natural sidechains, are all available at http://www.swisssidechain.ch. Our results enable researchers to rapidly and efficiently work with hundreds of non-natural sidechains.

Genomewide association study using a high-density single nucleotide polymorphism array and case-control design identifies a novel essential hypertension susceptibility locus in the promoter region of endothelial NO synthase.

Essential hypertension is a multifactorial disorder and is the main risk factor for renal and cardiovascular complications. The research on the genetics of hypertension has been frustrated by the small predictive value of the discovered genetic variants. The HYPERGENES Project investigated associations between genetic variants and essential hypertension pursuing a 2-stage study by recruiting cases and controls from extensively characterized cohorts recruited over many years in different European regions. The discovery phase consisted of 1865 cases and 1750 controls genotyped with 1M Illumina array. Best hits were followed up in a validation panel of 1385 cases and 1246 controls that were genotyped with a custom array of 14 055 markers. We identified a new hypertension susceptibility locus (rs3918226) in the promoter region of the endothelial NO synthase gene (odds ratio: 1.54 [95% CI: 1.37-1.73]; combined P=2.58 · 10(-13)). A meta-analysis, using other in silico/de novo genotyping data for a total of 21 714 subjects, resulted in an overall odds ratio of 1.34 (95% CI: 1.25-1.44; P=1.032 · 10(-14)). The quantitative analysis on a population-based sample revealed an effect size of 1.91 (95% CI: 0.16-3.66) for systolic and 1.40 (95% CI: 0.25-2.55) for diastolic blood pressure. We identified in silico a potential binding site for ETS transcription factors directly next to rs3918226, suggesting a potential modulation of endothelial NO synthase expression. Biological evidence links endothelial NO synthase with hypertension, because it is a critical mediator of cardiovascular homeostasis and blood pressure control via vascular tone regulation. This finding supports the hypothesis that there may be a causal genetic variation at this locus.

iLOGP: A Simple, Robust, and Efficient Description of n-Octanol/Water Partition Coefficient for Drug Design Using the GB/SA Approach.

The n-octanol/water partition coefficient (log Po/w) is a key physicochemical parameter for drug discovery, design, and development. Here, we present a physics-based approach that shows a strong linear correlation between the computed solvation free energy in implicit solvents and the experimental log Po/w on a cleansed data set of more than 17,500 molecules. After internal validation by five-fold cross-validation and data randomization, the predictive power of the most interesting multiple linear model, based on two GB/SA parameters solely, was tested on two different external sets of molecules. On the Martel druglike test set, the predictive power of the best model (N = 706, r = 0.64, MAE = 1.18, and RMSE = 1.40) is similar to six well-established empirical methods. On the 17-drug test set, our model outperformed all compared empirical methodologies (N = 17, r = 0.94, MAE = 0.38, and RMSE = 0.52). The physical basis of our original GB/SA approach together with its predictive capacity, computational efficiency (1 to 2 s per molecule), and tridimensional molecular graphics capability lay the foundations for a promising predictor, the implicit log P method (iLOGP), to complement the portfolio of drug design tools developed and provided by the SIB Swiss Institute of Bioinformatics.

Design effect and interviewer effects: Evidence from the Spanish ESS3-2006 Data

In 2007 the first Quality Enhancement Meeting on sampling in the European SocialSurvey (ESS) took place. The discussion focused on design effects and inteviewereffects in face-to-face interviews. Following the recomendations of this meeting theSpanish ESS team studied the impact of interviewers as a new element in the designeffect in the response s variance using the information of the correspondent SampleDesign Data Files. Hierarchical multilevel and cross-classified multilevel analysis areconducted in order to estimate the amount of responses variation due to PSU and tointerviewers for different questions in the survey. Factor such as the age of theinterviewer, gender, workload, training and experience and respondent characteristicssuch as age, gender, renuance to participate and their possible interactions are alsoincluded in the analysis of some specific questions like trust in politicians and trustin legal system . Some recomendations related to future sampling designs and thecontents of the briefing sessions are derived from this initial research.

O Estereótipo na Publicidade em Cabo verde Estudo de Caso das Publicidades produzidas pela Design Comunicação e Imagem (DECO)

O presente trabalho monográfico intitulado “O estereótipo na publicidade em Cabo Verde – Estudo de Caso das Publicidades Produzida pela Design Comunicação e Imagem”, enquadra-se no âmbito do curso de licenciatura em Ciências da Comunicação, vertente Publicidade realizado pela universidade Jean Piaget de Cabo Verde. O presente trabalho visa apresentar as noções conceptuais do estereótipo e a sua dinâmica na publicidade e argumentar sobre alguns efeitos que este elemento pode promover no discurso publicitário. Assim, propôs-se como estudo de caso as publicidades criadas pela empresa DECO: O objectivo é, essencialmente, caracterizar a publicidade que se faz em Cabo Verde, verificando se os publicitários cabo-verdianos estão a explorar os recursos de que dispõem, designadamente os valores, os estilos de vida, estereótipos, etc., para chegar aos seus consumidores. Com a realização deste trabalho, chegou-se a conclusão que, o estereótipo faz parte da vida do homem para o bem ou para o mal. Sem a sua presença seria muito complicado perceber ou descodificar alguns fenómenos que acontecem na sociedade. O estereótipo ajuda na compreensão de informações que a primeira seria complexo de interpretar, tornando-a fácil.

Design of new promoters and of a dual-bioreporter based on cross-activation by the two regulatory proteins XylR and HbpR.

The HbpR protein is the sigma54-dependent transcription activator for 2-hydroxybiphenyl degradation in Pseudomonas azelaica. The ability of HbpR and XylR, which share 35% amino acid sequence identity, to cross-activate the PhbpC and Pu promoters was investigated by determining HbpR- or XylR-mediated luciferase expression and by DNA binding assays. XylR measurably activated the PhbpC promoter in the presence of the effector m-xylene, both in Escherichia coli and Pseudomonas putida. HbpR weakly stimulated the Pu promoter in E. coli but not in P. azelaica. Poor HbpR-dependent activation from Pu was caused by a weak binding to the operator region. To create promoters efficiently activated by both regulators, the HbpR binding sites on PhbpC were gradually changed into the XylR binding sites of Pu by site-directed mutagenesis. Inducible luciferase expression from mutated promoters was tested in E. coli on a two plasmid system, and from mono copy gene fusions in P. azelaica and P. putida. Some mutants were efficiently activated by both HbpR and XylR, showing that promoters can be created which are permissive for both regulators. Others achieved a higher XylR-dependent transcription than from Pu itself. Mutants were also obtained which displayed a tenfold lower uninduced expression level by HbpR than the wild-type PhbpC, while keeping the same maximal induction level. On the basis of these results, a dual-responsive bioreporter strain of P. azelaica was created, containing both XylR and HbpR, and activating luciferase expression from the same single promoter independently with m-xylene and 2-hydroxybiphenyl.

Sociétés anonymes de famille : structure, maintien et optimisation de la détention du capital

Introduction générale : D'après une étude réalisée en Suisse en 2004, les entreprises de famille représentent 88,14% des entreprises, dont 80,2% sont constitués en sociétés anonymes. Les chiffres parlent d'eux-mêmes : les sociétés anonymes de famille occupent une place considérable dans le paysage des entreprises suisses. Les sociétés anonymes de famille correspondent donc à une réalité pratique. Juridiquement, la notion de société de famille n'apparaît pas dans le Code des obligations ; les sociétés anonymes de famille revêtent la forme juridique de la société anonyme, qui représente l'entreprise commerciale la plus courante en pratique. Le Code des obligations, à ses art. 620 ss, se limite à donner un cadre général de réglementation, ce qui a notamment pour conséquence que la forme juridique de la société anonyme s'adapte à des entités très variées, dans toutes sortes de secteurs d'activité, que ce soient des petites et moyennes entreprises ou de grandes multinationales, des sociétés capitalistes et impersonnelles ou des sociétés purement privées. Selon la conception générale de la forme juridique de la société anonyme, celle-ci revêt en principe un caractère capitaliste. L'intérêt de l'actionnaire pour la société anonyme est normalement de nature financière. Le fait que la qualité d'actionnaire soit matérialisée dans un titre, l'action, implique tant une certaine liquidité de l'actionnariat qu'une dépersonnalisation des rapports entre les membres qui composent la société anonyme. A l'opposé, la famille repose sur des liens personnels particuliers, étroits, avec notamment des dimensions psychologiques, affectives, émotives. Au premier abord, société anonyme et famille semblent donc antinomiques. Cette dichotomie présente un intérêt dogmatique. Elle correspond en outre à l'un des principaux enjeux : comment tenir compte des intérêts d'une entité fortement personnalisée - la famille - dans une structure impersonnelle et de type capitaliste - la société anonyme ? Le fait que le Code des obligations se limite à donner un cadre général de réglementation prend alors ici toute son importance ; la marge de manoeuvre et la liberté d'aménagement que le législateur accorde aux sociétés anonymes r vont permettre - ou alors empêcher - d'adapter la forme juridique de la société anonyme aux besoins d'une entité personnalisée comme la famille. Cette liberté n'est donc pas sans limites et les membres de la famille devront peut-être aussi assumer les conséquences du choix de cette forme de société. Partant, le but de notre travail est d'étudier les raisons d'être, l'organisation et la pérennité des sociétés anonymes de famille, spécifiquement sous l'angle du maintien du caractère familial de la société. Nous nous concentrerons sur la détention du capital, mais aussi sur sa structure, son maintien et son optimisation ; nous aborderons ainsi notamment les questions relatives à la transmissibilité des actions. Au regard de l'ampleur du sujet, nous avons dû procéder à certains choix, parfois arbitraires, notamment en raison des implications presque infinies des règles avec d'autres domaines. Nous nous limiterons ainsi, dans la première partie, à exposer les notions de base employées dans la suite de notre travail et nous focaliserons sur l'élaboration des définitions d'entreprise, société et société anonyme de famille, prémisses non seulement essentielles sous l'angle théorique, mais aussi fondamentales pour nos développements ultérieurs. S'agissant ensuite de l'analyse des possibilités d'aménagement d'une société anonyme dans le cadre du maintien du caractère familial de la société, nous nous concentrerons sur les règles relatives à la société anonyme et étudierons les limites qu'elles imposent et la liberté qu'elles offrent aux actionnaires familiaux. Nous laisserons en revanche de côté les problématiques particulières de la protection des actionnaires minoritaires et des organes. Enfin, si nous traitons toutes les notions théoriques nécessaires à la compréhension de chaque thématique présentée, seules celles primordiales et déterminantes sous l'angle de la conservation de l'hégémonie familiale seront approfondies. Nous avons structuré notre étude en quatre titres. Dans un premier titre, nous développerons les notions et principes élémentaires de notre sujet. Nous rappellerons ainsi la définition et les particularités de la société anonyme en général, y compris les sources et les modifications législatives, et les conditions de la cotation en bourse. Au stade des notions introductives, nous devrons également définir la société anonyme de famille, en particulier en établissant les éléments de la définition. Qu'entend-on par famille ? Quels critères permettent de qualifier une société anonyme de « société anonyme de famille » ? La définition de la société anonyme de famille devra être à la fois suffisamment précise, afin que cette notion puisse être appréhendée de manière adéquate pour la suite de notre travail, et suffisamment large, pour qu'elle englobe toute la variété des sociétés anonymes de famille. Nous présenterons aussi les raisons du choix de la forme juridique de la société anonyme pour une société de famille. Nous terminerons nos développements introductifs par un exposé relatif à la notion d'action et à son transfert en sa qualité de papier-valeur, préalables nécessaires à nos développements sur la transmissibilité des actions. Nous mettrons ainsi en évidence les conditions de transfert des actions, en tenant compte de la tendance à la dématérialisation des titres. Une fois ces éléments mis en place, qui nous donneront une première idée de la structure du capital d'une société anonyme de famille, nous devrons préciser la manière dont le capital doit être structuré. Nous chercherons comment il peut être maintenu en mains de la famille et si d'autres moyens n'ayant pas directement trait au capital peuvent être mis en oeuvre. Ainsi, dans un deuxième titre, nous analyserons les dispositions statutaires relatives à la structure du capital et à son maintien en mains familiales, en particulier les restrictions au transfert des actions nominatives. Les dispositions statutaires constituent-elles un moyen adéquat pour maintenir le caractère familial de la société ? Quelles sont les conditions pour limiter le transfert des actions ? Le caractère familial de la société peut-il être utilisé afin de restreindre le transfert des actions ? Les solutions sont-elles différentes si les actions sont, en tout ou en partie, cotées en bourse ? Nous traiterons aussi, dans ce même titre, les modalités du droit de vote et déterminerons si des dispositions statutaires peuvent être aménagées afin de donner plus de voix aux actions des membres de la famille et ainsi d'optimiser la détention du capital. Nous examinerons, dans notre troisième titre, un acte qui a trait à la fois au droit des contrats et au droit de la société anonyme, la convention d'actionnaires. En quoi consistent ces contrats ? Quels engagements les actionnaires familiaux peuvent-ils et doivent-ils prendre ? Quelle est l'utilité de ces contrats dans les sociétés anonymes de famille ? Quelles en sont les limites ? Les clauses conventionnelles peuvent-elles être intégrées dans les statuts ? Comment combiner les différentes clauses de la convention entre elles ? Dans ce même titre, nous étudierons également la concrétisation et la mise en application des dispositions statutaires et des clauses conventionnelles, afin de déterminer si, combinées, elles constituent des moyens adéquats pour assurer la structure, le maintien et l'optimisation de la détention du capital. Enfin, dans le quatrième et dernier titre, qui est davantage conçu comme un excursus, nous nous éloignerons du domaine strict du droit des sociétés (et des contrats) pour envisager certains aspects matrimoniaux et d'ordre successoral. En effet, puisque la famille est à la base de la société, il convient de relever l'importance des règles matrimoniales et successorales pour les sociétés anonymes de famille et leur incidence sur la détention des actions et le maintien du caractère familial de la société. Nous examinerons en particulier comment ces instruments doivent être utilisés pour qu'ils n'annihilent pas les efforts entrepris pour conserver la société en mains familiales. Notre travail a pour but et pour innovation de présenter une analyse transversale aussi complète que possible du droit de la société anonyme et des instruments connexes en étudiant les moyens à disposition des actionnaires d'une société anonyme de type personnel, la société anonyme de famille. Il tentera ainsi d'apporter une approche théorique nouvelle de ces questions, de présenter certains aspects de manière pragmatique, d'analyser la mise en oeuvre des différents moyens étudiés et de discuter leur opportunité.

A double-quadrature radiofrequency coil design for proton-decoupled carbon-13 magnetic resonance spectroscopy in humans at 7T

Purpose Carbon-13 magnetic resonance spectroscopy (13C-MRS) is challenging because of the inherent low sensitivity of 13C detection and the need for radiofrequency transmission at the 1H frequency while receiving the 13C signal, the latter requiring electrical decoupling of the 13C and 1H radiofrequency channels. In this study, we added traps to the 13C coil to construct a quadrature-13C/quadrature-1H surface coil, with sufficient isolation between channels to allow simultaneous operation at both frequencies without compromise in coil performance. Methods Isolation between channels was evaluated on the bench by measuring all coupling parameters. The quadrature mode of the quadrature-13C coil was assessed using in vitro 23Na gradient echo images. The signal-to-noise ratio (SNR) was measured on the glycogen and glucose resonances by 13C-MRS in vitro, compared with that obtained with a linear-13C/quadrature-1H coil, and validated by 13C-MRS in vivo in the human calf at 7T. Results Isolation between channels was better than â^'30 dB. The 23Na gradient echo images indicate a region where the field is strongly circularly polarized. The quadrature coil provided an SNR enhancement over a linear coil of 1.4, in vitro and in vivo. Conclusion It is feasible to construct a double-quadrature 13C-1H surface coil for proton decoupled sensitivity enhanced 13C-NMR spectroscopy in humans at 7T.
