Anorectal anomalies associated with or as part of other anomalies.

Anorectal anomalies occurring with other anomalies or as part of syndromes were analyzed to determine how their epidemiological characteristics differed from those of isolated anal anomalies. Almost 15% of cases were chromosomal, monogenic or teratogenic syndromes, whereas the rest were of unknown cause including sequences (9.3%), VACTERL associations (15.4%) and multiple congenital anomalies (MCA) (60.2%). Almost half of babies with MCA had one or two VACTERL anomalies with distribution frequencies that did not differ significantly from those in babies with the full VACTERL association. There were considerable differences in the frequency of the VACTERL association among babies with different types of anorectal anomaly. Babies with anal anomalies occurring with sequences, VACTERL or MCA showed the same sex differences as babies with isolated anal anomalies, namely male predominance in anal atresia without fistula or cloaca, no sex difference in anal atresia with fistula, and female predominance in ectopic anus and congenital anal fistula. These anomalies, however, were associated with significantly lower mean gestational lengths and birth weights, and higher frequencies of fetal death and pregnancy termination than babies with isolated anal anomalies. Twins were more frequent in sequences, VACTERL and MCA than in isolated anomalies, monogenic syndromes or chromosome anomalies. Five cases were conjoined twins, representing 15% of all cases of twin pregnancies with an anal anomaly. Indeterminate sex was more frequent in babies with anal atresias without fistula than in those with fistula. Anal anomalies are defects of blastogenesis attributable to disorders in expression of pattern determining genes. The differential sex involvement in different types of anal anomaly may be manifestations of expression of the HY/SRY genes during blastogenesis or of X-linkage.

Road Safety Audit for Intersection of IA 1 and County Road R-67 in Johnson County, Iowa, 2009

On August 3, 2009, a road safety audit was initiated for the intersection of IA 1 and County Road F-67 in Johnson County, Iowa. Due to the high volume of traffic accessing the cheese producing plant (Twin County Dairy, Inc.), a grocery store east of the intersection, and a large Amish community with horse-drawn wagons and carriages frequently sharing the roads with motorized vehicles, this intersection has developed a crash history that concerns the Iowa Department of Transportation (Iowa DOT), Iowa State Patrol, and local agencies. Considering this, Johnson County and the Iowa DOT requested that a road safety audit be conducted to address the safety concerns and recommend possible mitigation strategies.

Meiotic drive favors Robertsonian metacentric chromosomes in the common shrew (Sorex araneus, Insectivora, mammalia).

Meiotic drive has attracted much interest because it concerns the robustness of Mendelian segregation and its genetic and evolutionary stability. We studied chromosomal meiotic drive in the common shrew (Sorex araneus, Insectivora, Mammalia), which exhibits one of the most remarkable chromosomal polymorphisms within mammalian species. The open question of the evolutionary success of metacentric chromosomes (Robertsonian fusions) versus acrocentrics in the common shrew prompted us to test whether a segregation distortion in favor of metacentrics is present in female and/or male meiosis. Performing crosses under controlled laboratory conditions with animals from natural populations, we found a clear trend toward a segregation distortion in favor of metacentrics during male meiosis, two chromosome combinations (gm and jl) being significantly preferred over their acrocentric homologs. Apart for one Robertsonian fusion (hi), this trend was absent in female meiosis. We propose a model based on recombination events between twin acrocentrics to explain the difference in transmission ratios of the same metacentric in different sexes and unequal drive of particular metacentrics in the same sex. Pooled data for female and male meiosis revealed a trend toward stronger segregation distortion for larger metacentrics. This is partially in agreement with the frequency of metacentrics occurring in natural populations of a chromosome race showing a high degree of chromosomal polymorphism.

Prise en charge des plaies, quoi de neuf? [Advances in wound care]

Wound care made great progress during last years related to several factors. The first is an awakening of the importance of wounds. The progress made in the comprehension of the physiopathology of wounds led to innovations in all stages of this complex process which is the wound healing. Autologus platelet concentrate producing growth factors are in use to stimulate the first phase of the healing. The second phase which is the phase of proliferation and secretion is currently better managed with new categories of bandages which are true local treatments. The nutrition became one of the pillars of wound treatments especially among old patients. The reconstructive surgery took great steps since the physiology and the vascular anatomy of the skin and soft tissues are better known. Finally the bio-engineering has entered the treatment of the wound there is more than 20 years ago and methods have improved and become more reliable

Kulttuurierot kaksoiskaupunkiyhteistyössä Case: Imatra-Svetogorsk

The primary target of this study is to examine what kind of cultural differences have been noticed in co-operation concerning twin-city of Finnish town Imatra and Russian town Svetogorsk. The secondary purpose of the study is to analyse influences of cultural differences on leadership in this twin-city project and it's realizing. The case study has been carried out by qualitative research method. The research material has been gathered mainly by interviews. The results of the study show that cultural differences in twin-city co-operation are most clearly associated with the culture of the administration, attitude towards relations, communication style and the meaning of planning and time. The results also show that it has been realized both in Imatra and in Svetogorsk, that culture is a significant factor when people work together. Although its influence on leadership has not been analysed completely. The activities are mostly guided by common goals.

The business model ontology a proposition in a design science approach

The goal of this dissertation is to find and provide the basis for a managerial tool that allows a firm to easily express its business logic. The methodological basis for this work is design science, where the researcher builds an artifact to solve a specific problem. In this case the aim is to provide an ontology that makes it possible to explicit a firm's business model. In other words, the proposed artifact helps a firm to formally describe its value proposition, its customers, the relationship with them, the necessary intra- and inter-firm infrastructure and its profit model. Such an ontology is relevant because until now there is no model that expresses a company's global business logic from a pure business point of view. Previous models essentially take an organizational or process perspective or cover only parts of a firm's business logic. The four main pillars of the ontology, which are inspired by management science and enterprise- and processmodeling, are product, customer interface, infrastructure and finance. The ontology is validated by case studies, a panel of experts and managers. The dissertation also provides a software prototype to capture a company's business model in an information system. The last part of the thesis consists of a demonstration of the value of the ontology in business strategy and Information Systems (IS) alignment. Structure of this thesis: The dissertation is structured in nine parts: Chapter 1 presents the motivations of this research, the research methodology with which the goals shall be achieved and why this dissertation present a contribution to research. Chapter 2 investigates the origins, the term and the concept of business models. It defines what is meant by business models in this dissertation and how they are situated in the context of the firm. In addition this chapter outlines the possible uses of the business model concept. Chapter 3 gives an overview of the research done in the field of business models and enterprise ontologies. Chapter 4 introduces the major contribution of this dissertation: the business model ontology. In this part of the thesis the elements, attributes and relationships of the ontology are explained and described in detail. Chapter 5 presents a case study of the Montreux Jazz Festival which's business model was captured by applying the structure and concepts of the ontology. In fact, it gives an impression of how a business model description based on the ontology looks like. Chapter 6 shows an instantiation of the ontology into a prototype tool: the Business Model Modelling Language BM2L. This is an XML-based description language that allows to capture and describe the business model of a firm and has a large potential for further applications. Chapter 7 is about the evaluation of the business model ontology. The evaluation builds on literature review, a set of interviews with practitioners and case studies. Chapter 8 gives an outlook on possible future research and applications of the business model ontology. The main areas of interest are alignment of business and information technology IT/information systems IS and business model comparison. Finally, chapter 9 presents some conclusions.

Niños "vergonzantes" y "pequeños rojos". La población marginal infantil en la Cataluña interior del primer franquismo

En el imaginario colectivo de la sociedad de posguerra siempre están presentes las duras condiciones de la vida cotidiana. La población infantil fue especialmente sensible a esta situación debido al alto índice de enfermedades infecciosas, el racionamiento dietético y las angustias derivadas del conflicto bélico. En estas condiciones, el Auxilio Social de la Falange fue el encargado de administrar la beneficencia y, a su vez, resocializar la población, en este caso, la infantil, dentro de los valores nacionalsindicalistas y nacionalcatólicos. Ello le permitió no sólo controlar la política social sino también criminalizar a los vencidos en el momento de administrarla. En definitiva, fue uno de los pilares fundamentales en el proceso de construcción del edificio franquista.

Hacia la arquitectura de la información 3.0: pasado, presente y futuro

La arquitectura de la información (IA), aunque presente en cierta manera desde hace más de 50 años, ha tomado especial relevancia con la llegada de la Web y el aumento de la cantidad de información a nuestro alcance. La disciplina cuenta ya con unos pilares claros, que se fundamentan en los contenidos gestionados pero sobre todo en los usuarios, sin olvidar su contexto. También se identifica una serie de componentes a combinar a la hora de elaborar una IA y una metodología básica. Pero la cantidad de información a nuestro alcance no para de crecer, así que se continúa innovando en nuevas formas de organización, buscadores más eficaces o tecnologías de web semántica que permiten a los ordenadores encargarse de la parte menos creativa de enfrentarse a esa avalancha de información.

Tandem-GMA Welding of Low Alloy Structural Steel

The Tandem-GMAW method is the latest development as the consequences of improvements in the welding methods. The twin-wire and then the Tandem-method with the separate power sources has got a remarkable place in the welding of many types of materials with different joint types. The biggest advantage of Tandem welding method is the flexibility of choosing both the electrodes of different types from each other according to the type of the parent material. This is possible because of the feasibility of setting the separate welding parameters for both the wires. In this thesis work the effect of the variation in three parameters on the weld bead in Tandem-GMA welding method is studied. Theses three parameters are the wire feed rate in the slave wire, the wire feed rate in the master wire and the voltage difference in both the wires. The results are then compared to study the behaviour of the weld bead with the change in these parameters.

Genetic origin of the relationship between parental negativity and behavior problems from early childhood to adolescence: A longitudinal genetically sensitive study.

Little is known about how genetic and environmental factors contribute to the association between parental negativity and behavior problems from early childhood to adolescence. The current study fitted a cross-lagged model in a sample consisting of 4,075 twin pairs to explore (a) the role of genetic and environmental factors in the relationship between parental negativity and behavior problems from age 4 to age 12, (b) whether parent-driven and child-driven processes independently explain the association, and (c) whether there are sex differences in this relationship. Both phenotypes showed substantial genetic influence at both ages. The concurrent overlap between them was mainly accounted for by genetic factors. Causal pathways representing stability of the phenotypes and parent-driven and child-driven effects significantly and independently account for the association. Significant but slight differences were found between males and females for parent-driven effects. These results were highly similar when general cognitive ability was added as a covariate. In summary, the longitudinal association between parental negativity and behavior problems seems to be bidirectional and mainly accounted for by genetic factors. Furthermore, child-driven effects were mainly genetically mediated, and parent-driven effects were a function of both genetic and shared-environmental factors.

Pankkien vakavaraisuussäännöstön uudistus

Tutkielman tavoitteena on kuvata pankkien vakavaraisuusuudistuksen eri osa-alueita. Tarkempi analyysi rajautuu uudistuksen tuomiin muutoksiin luotto- ja operatiivisen riskin pääomavaateissa. Tutkielman empiirisen osuuden tavoitteena on perehtyä vakavaraisuussäännöstön uudistusten vaikutuksiin Nordeassa. Tutkimusmetodologiaksi on valittu normatiivinen tutkimusote. Lisäksi tutkielma sisältää deskriptiivisiä ja positivistisia osia. Lähdeaineisto koostuu Baselin pankkivalvontakomitean ja Suomen Pankin julkaisemista tutkimuksista ja dokumenteista sekä alan julkaisuissa ilmestyneistä artikkeleista. Pankkien vakavaraisuussäännöstöuudistuksen tavoitteena on lisätä rahoitusmarkkinoiden vakautta. Sääntelyn kautta pyritään turvaamaan pankkien varojen riittävyys suhteessa niiden riskien ottoon. Vakavaraisuussäännöstön uudistus muodostuu kolmesta pilarista: (1) minimipääomavaatimuksista, (2) pankkivalvonnan vahvistamisesta ja (3) markkinakurin hyödyntämisestä luottolaitosten toiminnan julkistamisvaatimuksia lisäämällä. Pankkivalvonnan harmonisoinnista vallitsee kansainvälinen yhteisymmärrys, mutta ennen kuin Basel II voi astua voimaan on useita ongelmia ratkaisematta. Baselin vakavaraisuuskehikko ei ole ainut lähitulevaisuudessa pankkitoimialaa koetteleva uudistus. Kansainväliset tilinpäätösstandardit; International Accounting Standards ja erityisesti IAS 39 sekä International Financial Reporting Standards, lyhyemmin IFRS tulevat muuttamaan merkittävästi pankkien tilinpäätöskäyttäytymistä. Epäselvää on vielä kuitenkin tukevatko uudistukset toisiaan ja missä määrin pankkien tulosvolatiliteetin odotetaan kasvavan. Tutkielmassa pohditaan vakavaraisuussäännöstön uudistuksen hyötyjä kansainvälisen kilpailuneutraliteetin osalta, sillä Yhdysvalloissa uudistus koskee vain suurimpia pankkeja. Tutkielmassa paneudutaan lisäksi uudistuksen mahdolliseen talouden syklejä voimistavaan vaikutukseen ja tarkastellaan parannusehdotuksia prosyklisyyden hillitsemiseksi. Yksi vakavaraisuusuudistuksen tärkeimmistä tehtävistä on luoda pankeille kannustin kehittää omia riskienhallinta malleja. Kannustin ongelma on pyritty ratkaisemaan vapaampien sisäisten mallien menetelmien avulla. Ongelmaa ei ole pystytty kuitenkaan ratkaisemaan aivan täysin, sillä luottoriskien osalta pankkien lainaportfolioiden rakenne määrittää sen, hyötyvätkö pankit siirtymisestä sisäisten mallien menetelmän käyttöön. Tutkielma sisältää myös Nordean arvion vakavaraisuusuudistuksen vaikutuksista pankkitoimialaan.

Pankkien vakavaraisuuskehikon uudistaminen erityisesti markkinakurin edellytysten kannalta

Tutkielman tavoitteena on kuvata ja analysoida valmisteilla olevan pankkien vakavaraisuuskehikon uudistuksen eri osa-alueita erityisesti markkinakurin edellytysten parantamisen kannalta keskittyen julkistamisvaatimuksiin. Lisäksi tutkielmassa arvioidaan koko uudistuksen pankille ja sen eri intressiryhmille aiheuttamia seurauksia, uudistuksen hyviä ja huonoja puolia sekä mahdollisia ongelmakohtia. Tutkielma perustuu Baselin pankkivalvontakomitean ja Euroopan komission toisiin ehdotuksiin vakavaraisuuskehikon uudistamiseksi. Lisää perspektiiviä antavat aiheesta kirjoitetut artikkelit ja julkaisut sekä haastattelut. Pankkien vakavaraisuuskehikon uudistus muodostuu kolmesta toisiaan täydentävästä niin kutsutusta pilarista, jotka ovat 1) vähimmäisvakavaraisuuden laskentatapa, 2) valvontaprosessin vahvistaminen ja 3) markkinakurin edellytysten parantaminen. Uudistus on vielä kesken ja sen sisältö muuttuu jatkuvasti eri tahojen kantojen kirkastuessa. Varsinaisten johtopäätösten teko on siis vielä liian aikaista, mutta jo nyt on selvää, että kyseessä on laaja ja merkittävä uudistus. Se muun muassa mahdollistaa sisäisten riskiluokitusten käytön ja kannustaa pankkeja tehokkaampaan riskien hallintaan sekä moninkertaistaa julkistettavan tiedon määrän nykyiseen säännöstöön verrattuna. Uudistuksen suuntalinjoista vallitsee kansainvälinen yhteisymmärrys, mutta monia ongelmia on vielä ratkaistava. Sen vuoksi laatijatahot ovat päättäneet antaa vielä kolmannen ehdotuksen ennen lopullista päätöstä. Suurimpia huolenaiheita ovat tällä hetkellä yhdenmukainen kansainvälinen täytäntöönpano ja säännösten tasapuolinen noudattaminen. Myös kehikon yksityiskohtaisuus arveluttaa monia.

Fetal laser therapy: applications in the management of fetal pathologies.

Fetoscopic coagulation of placental anastomoses is the treatment of choice for severe twin-to-twin transfusion syndrome. In the present day, fetal laser therapy is also used to treat amniotic bands, chorioangiomas, sacrococcygeal teratomas, lower urinary tract obstructions and chest masses, all of which will be reviewed in this article. Amniotic band syndrome can cause limb amputation by impairing downstream blood flow. Large chorioangiomas (>4 cm), sacrococcygeal teratomas or fetal hyperechoic lung lesions can lead to fetal compromise and hydrops by vascular steal phenomenon or compression. Renal damage, bladder dysfunction and lastly death because of pulmonary hypolasia may be the result of megacystis caused by a posterior urethral valve. The prognosis of these pathologies can be dismal, and therapy options are limited, which has brought fetal laser therapy to the forefront. Management options discussed here are laser release of amniotic bands, laser coagulation of the placental or fetal tumor feeding vessels and laser therapy by fetal cystoscopy. This review, largely based on case reports, does not intend to provide a level of evidence supporting laser therapy over other treatment options. Centralized evaluation by specialists using strict selection criteria and long-term follow-up of these rare cases are now needed to prove the value of endoscopic or ultrasound-guided laser therapy.

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.
