Senyals i espills

L'objectiu d'aquest article és discutir una antiga matriu comunicativa parcialment assenyalada per A. Comte, Ch. S. Peirce i U. Eco. Aquests autors reconegueren la relació entre marques, fletxes, ensenyes i espills com a diferents metàfores bàsiques de diverses operacions cognitives, encara que no en van presentar una visió de conjunt. Tots tres van treballar la distinció entre metàfora i metonímia, que va resultar tan fructífera en diferents dominis de recerca, com Jakobson (entre altres) ens va ensenyar. La meua hipòtesi és que aquestes quatre metàfores bàsiques (marques, fletxes, ensenyes i espills) es poden deduir correctament d'una matriu que relacioni l'eix metàfora-metonímia amb menes de codi ficació. E. Verón llançà una interessant reflexió sobre els modes analògic i digital, tot partint d'un problema semblant. Marques, etxes, ensenyes i miralls poden recordar bé operacions com senyalar i assenyalar, representar i reflectir, respectivament: estipular de manera aproximada com aquests objectes i aquestes operacions estan connectats podria ser una petita contribució a l'antic programa de Peirce i els altres.

Genome-wide meta-analysis identifies six novel loci associated with habitual coffee consumption

Coffee, a major dietary source of caffeine, is among the most widely consumed beverages in the world and has received considerable attention regarding health risks and benefits. We conducted a genome-wide (GW) meta-analysis of predominately regular-type coffee consumption (cups per day) among up to 91 462 coffee consumers of European ancestry with top single-nucleotide polymorphisms (SNPs) followed-up in ~30 062 and 7964 coffee consumers of European and African-American ancestry, respectively. Studies from both stages were combined in a trans-ethnic meta-analysis. Confirmed loci were examined for putative functional and biological relevance. Eight loci, including six novel loci, met GW significance (log10Bayes factor (BF)>5.64) with per-allele effect sizes of 0.03-0.14 cups per day. Six are located in or near genes potentially involved in pharmacokinetics (ABCG2, AHR, POR and CYP1A2) and pharmacodynamics (BDNF and SLC6A4) of caffeine. Two map to GCKR and MLXIPL genes related to metabolic traits but lacking known roles in coffee consumption. Enhancer and promoter histone marks populate the regions of many confirmed loci and several potential regulatory SNPs are highly correlated with the lead SNP of each. SNP alleles near GCKR, MLXIPL, BDNF and CYP1A2 that were associated with higher coffee consumption have previously been associated with smoking initiation, higher adiposity and fasting insulin and glucose but lower blood pressure and favorable lipid, inflammatory and liver enzyme profiles (P<5 × 10-8).Our genetic findings among European and African-American adults reinforce the role of caffeine in mediating habitual coffee consumption and may point to molecular mechanisms underlying inter-individual variability in pharmacological and health effects of coffee.

Ash2 acts as an Ecdysone Receptor coactivator by stabilizing the histone methyltransferase Trr.

The molting hormone ecdysone triggers chromatin changes via histone modifica- tions that are important for gene regulation. On hormone activation, the ecdysone receptor (EcR) binds to the SET domain-containing histone H3 methyltransferase trithorax-related protein (Trr). Methylation of histone H3 at lysine 4 (H3K4me), which is associated with tran- scriptional activation, requires several cofactors, including Ash2. We find that ash2 mutants have severe defects in pupariation and metamorphosis due to a lack of activation of ecdy- sone-responsive genes. This transcriptional defect is caused by the absence of the H3K4me3 marks set by Trr in these genes. We present evidence that Ash2 interacts with Trr and is re- quired for its stabilization. Thus we propose that Ash2 functions together with Trr as an ecdysone receptor coactivator.

Study on Accuracy of Judgments by Chinese Fingerprint Examiners

The interpretation of fingerprint evidence depends on the judgments of fingerprint examiners. This study assessed the accuracy of different judgments made by fingerprint examiners following the Analysis, Comparison, and Evaluation (ACE) process. Each examiner was given five marks for analysis, comparison, and evaluation. We compared the experts' judgments against the ground truth and used an annotation platform to evaluate how Chinese fingerprint examiners document their comparisons during the identification process. The results showed that different examiners demonstrated different accuracy of judgments and different mechanisms to reach them.

Detection of Clinically Significant Prostate Cancer Using Magnetic Resonance Imaging-Ultrasound Fusion Targeted Biopsy: A Systematic Review.

CONTEXT: The current standard for diagnosing prostate cancer in men at risk relies on a transrectal ultrasound-guided biopsy test that is blind to the location of the cancer. To increase the accuracy of this diagnostic pathway, a software-based magnetic resonance imaging-ultrasound (MRI-US) fusion targeted biopsy approach has been proposed. OBJECTIVE: Our main objective was to compare the detection rate of clinically significant prostate cancer with software-based MRI-US fusion targeted biopsy against standard biopsy. The two strategies were also compared in terms of detection of all cancers, sampling utility and efficiency, and rate of serious adverse events. The outcomes of different targeted approaches were also compared. EVIDENCE ACQUISITION: We performed a systematic review of PubMed/Medline, Embase (via Ovid), and Cochrane Review databases in December 2013 following the Preferred Reported Items for Systematic reviews and Meta-analysis statement. The risk of bias was evaluated using the Quality Assessment of Diagnostic Accuracy Studies-2 tool. EVIDENCE SYNTHESIS: Fourteen papers reporting the outcomes of 15 studies (n=2293; range: 13-582) were included. We found that MRI-US fusion targeted biopsies detect more clinically significant cancers (median: 33.3% vs 23.6%; range: 13.2-50% vs 4.8-52%) using fewer cores (median: 9.2 vs 37.1) compared with standard biopsy techniques, respectively. Some studies showed a lower detection rate of all cancer (median: 50.5% vs 43.4%; range: 23.7-82.1% vs 14.3-59%). MRI-US fusion targeted biopsy was able to detect some clinically significant cancers that would have been missed by using only standard biopsy (median: 9.1%; range: 5-16.2%). It was not possible to determine which of the two biopsy approaches led most to serious adverse events because standard and targeted biopsies were performed in the same session. Software-based MRI-US fusion targeted biopsy detected more clinically significant disease than visual targeted biopsy in the only study reporting on this outcome (20.3% vs 15.1%). CONCLUSIONS: Software-based MRI-US fusion targeted biopsy seems to detect more clinically significant cancers deploying fewer cores than standard biopsy. Because there was significant study heterogeneity in patient inclusion, definition of significant cancer, and the protocol used to conduct the standard biopsy, these findings need to be confirmed by further large multicentre validating studies. PATIENT SUMMARY: We compared the ability of standard biopsy to diagnose prostate cancer against a novel approach using software to overlay the images from magnetic resonance imaging and ultrasound to guide biopsies towards the suspicious areas of the prostate. We found consistent findings showing the superiority of this novel targeted approach, although further high-quality evidence is needed to change current practice.

Reklamaatioprosessin kehittäminen tavarataloketjussa

Tämän työn tavoitteena oli selvittää Sokoksen reklamaatioprosessin kehittämisessä saavutettavia etuja. Reklamaatiokäytäntö muuttui tämän työn aikana paperiversiosta sähköiseen muotoon, ja tässä on pyritty selvittämään muutosten vaikutuksia seurantaan ja ja toimintaan. Tavoitteena oli myös rakentaa prosessin seurannan kannalta tärkeitä mittareita kehityksen seurantaa varten.Sokos-ketjussa tehtiin vuonna 1999 yli 20 000 virheilmoitusta hankintayhtiöön. Näistä osa oli toimitusvirheitä ja osa tuotevirheitä. Reklamaatioiden arvoksi muodostui ostohinnoin lähes seitsemän miljoonaa markkaa. Reklamaatioiden suuresta määrästä johtuen Sokoksella katsottiin järkeväksi tehostaa reklamointia siirtymällä tekemään virheilmoitukset suoraan tietojärjestelmään ja välittämään ne sitä kautta automaattisesti hankintayhtiöön. Uuteen toimintamalliin siirryttiin 1.5.2000. Prosessissa saavutettuja etuja mitattiin tässä työssä järjestämällä henkilöstölle kysely, sekä mittaamalla ja arvioimalla ajansäästöjä. Investoinnin kannattavuutta tutkittiin erilaisten tulevaisuusnäkymien perusteella. Tutkimuksen perusteella uusi prosessi on helpottanut tekijöiden työtä, seuranta/mittaaminen on huomattavasti aiempaa tehokkaampaa, ja investointi muodostuu melko suurella todennäköisyydellä kannattavaksi tiettyjen hyvityssummiin liittyvien ehtojen täyttyessä.

Fingermark initial composition and aging using Fourier transform infrared microscopy (μ-FTIR)

This study investigated fingermark residues using Fourier transform infrared microscopy (μ- FTIR) in order to obtain fundamental information about the marks' initial composition and aging kinetics. This knowledge would be an asset for fundamental research on fingermarks, such as for dating purposes. Attenuated Total Reflection (ATR) and single-point reflection modes were tested on fresh fingermarks. ATR proved to be better suited and this mode was subsequently selected for further aging studies. Eccrine and sebaceous material was found in fresh and aged fingermarks and the spectral regions 1000-1850 cm-1 and 2700-3600 cm-1 were identified as the most informative. The impact of substrates (aluminium and glass slides) and storage conditions (storage in the light and in the dark) on fingermark aging was also studied. Chemometric analyses showed that fingermarks could be grouped according to their age regardless of the substrate when they were stored in an open box kept in an air-conditioned laboratory at around 20°C next to a window. On the contrary, when fingermarks were stored in the dark, only specimens deposited on the same substrate could be grouped by age. Thus, the substrate appeared to influence aging of fingermarks in the dark. Furthermore, PLS regression analyses were conducted in order to study the possibility of modelling fingermark aging for potential fingermark dating applications. The resulting models showed an overall precision of ±3 days and clearly demonstrated their capability to differentiate older fingermarks (20 and 34-days old) from newer ones (1, 3, 7 and 9-days old) regardless of the substrate and lighting conditions. These results are promising from a fingermark dating perspective. Further research is required to fully validate such models and assess their robustness and limitations in uncontrolled casework conditions.

Osakeyhtiön sivuuttaminen, kohdistamisongelmana tulonsaaja - OY vs. osakas

Tutkielman tavoitteena on tutkia veronkiertosäännöksen eli VML 28 §:n soveltamista sivuutettaessa osakeyhtiö verotuksessa. Tutkielma on rajattu tapauksiin, joissa osakeyhtiön tuloa on sivuutettu ja verotettu osakkaan palkkatulona. Tutkielma muodostuu lähinnä kirjallisuuteen ja lainsäädäntöön perustuvista teoriaosista sekä oikeuskäytäntöön pohjautuvasta tutkimusosasta. Tutkimus on oikeusdogmaattinen, eli tarkoituksena on selvittää voimassa olevan lainsäädännön sisältö. Tutkimuksessa on käyty läpi korkeimman hallinto-oikeuden ja hallinto-oikeuksien päätöksiä ja selvitetty näiden avulla kriteerejä, joita voidaan pitää tunnusmerkkeinä vallitsevasta palkkasuhteesta. Tämä saattaa johtaa verotuksessa osakeyhtiön tulon sivuuttamiseen. Päätös osakeyhtiön sivuuttamisesta tehdään kuitenkin aina kokonaisarvioinnin perusteella. Päätöksen lopputulokseen vaikuttaa kuitenkin merkittävästi mm. osakeyhtiön toimeksiantajien lukumäärä. Mikäli toimeksisaaja työskentelee hyvin samankaltaisissa olosuhteissa kuin toimeksiantajan työntekijät, voidaan osakeyhtiö verotuksessa sivuuttaa, mikäli tilanne tulee esille esim. verotarkastuksen yhteydessä.

Mistificat o infravalorat?, Urbanista o polític?: la figura d'Ildefons Cerdà a través de La Vanguardia, 1881-2010

La figura de l’urbanista i enginyer osonenc Ildefons Cerdà (1815-1876) ha estat objecte de controvèrsia entre els intel·lectuals de cada època. Però, públicament, no va ser fins als treballs de l’economista Fabià Estapé (1968-1971) que es va recuperar i reivindicar finalment el llegat del dissenyador de l’Eixample de Barcelona. En l’any que es commemoren els 150 anys del Pla Cerdà, aquest article té per objectiu revisar què n’ha dit la premsa d’època d’Ildefons Cerdà, usant com a base el material hemerogràfic de La Vanguardia.

General Equilibrium Analysis. A Century after Walras

2010 marks the hundredth anniversary of the death of Léon Walras, the brilliant originator and first formaliser of general equilibrium theory - one of the pillars of modern economic theory. In advancing much derided practical solutions Walras also displayed more concern for the problems of living in a second best world than is common in modern pure theories of the invisible hand, efficient market hypothesis, DSGE macroeconomics or the thinking of some contemporary free market admirers all based on general equilibrium theory. This book brings contributions from the likes of Kenneth Arrow, Alan Kirman, Richard Posner, Amartya Sen and Robert Solow to share their thoughts and reflections on the theoretical heritage of Léon Walras. Some authors reminisce on the part they played in the development of modern general economics theory; others reflect on the crucial part played by general equilibrium in the development of macroeconomics, microeconomics, growth theory, welfare economics and the theory of justice; others still complain about the wrong path economic theory took under the influence of post 1945 developments in general equilibrium theory.

Epigenetic Activation of SOX11 in Lymphoid Neoplasms by Histone Modifications

Recent studies have shown aberrant expression of SOX11 in various types of aggressive B-cell neoplasms. To elucidate the molecular mechanisms leading to such deregulation, we performed a comprehensive SOX11 gene expression and epigenetic study in stem cells, normal hematopoietic cells and different lymphoid neoplasms. We observed that SOX11 expression is associated with unmethylated DNA and presence of activating histone marks (H3K9/14Ac and H3K4me3) in embryonic stem cells and some aggressive B-cell neoplasms. In contrast, adult stem cells, normal hematopoietic cells and other lymphoid neoplasms do not express SOX11. Such repression was associated with silencing histone marks H3K9me2 and H3K27me3. The SOX11 promoter of non-malignant cells was consistently unmethylated whereas lymphoid neoplasms with silenced SOX11 tended to acquire DNA hypermethylation. SOX11 silencing in cell lines was reversed by the histone deacetylase inhibitor SAHA but not by the DNA methyltransferase inhibitor AZA. These data indicate that, although DNA hypermethylation of SOX11 is frequent in lymphoid neoplasms, it seems to be functionally inert, as SOX11 is already silenced in the hematopoietic system. In contrast, the pathogenic role of SOX11 is associated with its de novo expression in some aggressive lymphoid malignancies, which is mediated by a shift from inactivating to activating histone modifications.

Divergence with gene flow and fine-scale phylogeographical structure in the wedge-billed woodcreeper, Glyphorynchus spirurus, a Neotropical rainforest bird.

Determining the relative roles of vicariance and selection in restricting gene flow between populations is of central importance to the evolutionary process of population divergence and speciation. Here we use molecular and morphological data to contrast the effect of isolation (by mountains and geographical distance) with that of ecological factors (altitudinal gradients) in promoting differentiation in the wedge-billed woodcreeper, Glyphorynchus spirurus, a tropical forest bird, in Ecuador. Tarsus length and beak size increased relative to body size with altitude on both sides of the Andes, and were correlated with the amount of moss on tree trunks, suggesting the role of selection in driving adaptive divergence. In contrast, molecular data revealed a considerable degree of admixture along these altitudinal gradients, suggesting that adaptive divergence in morphological traits has occurred in the presence of gene flow. As suggested by mitochondrial DNA sequence data, the Andes act as a barrier to gene flow between ancient subspecific lineages. Genome-wide amplified fragment length polymorphism markers reflected more recent patterns of gene flow and revealed fine-scale patterns of population differentiation that were not detectable with mitochondrial DNA, including the differentiation of isolated coastal populations west of the Andes. Our results support the predominant role of geographical isolation in driving genetic differentiation in G. spirurus, yet suggest the role of selection in driving parallel morphological divergence along ecological gradients.
