Impact of the Spanish smoking control law on exposure to second-hand smoke and respiratory health in hospitality workers: a cohort study

A smoke-free law came into effect in Spain on 1st January 2006, affecting all enclosed workplaces except hospitality venues, whose proprietors can choose among totally a smoke-free policy, a partial restriction with designated smoking areas, or no restriction on smoking on the premises. We aimed to evaluate the impact of the law among hospitality workers by assessing second-hand smoke (SHS) exposure and the frequency of respiratory symptoms before and one year after the ban.

Congenital hypogonadotropic hypogonadism with split hand/foot malformation: a clinical entity with a high frequency of FGFR1 mutations.

PURPOSE: Congenital hypogonadotropic hypogonadism (CHH) and split hand/foot malformation (SHFM) are two rare genetic conditions. Here we report a clinical entity comprising the two. METHODS: We identified patients with CHH and SHFM through international collaboration. Probands and available family members underwent phenotyping and screening for FGFR1 mutations. The impact of identified mutations was assessed by sequence- and structure-based predictions and/or functional assays. RESULTS: We identified eight probands with CHH with (n = 3; Kallmann syndrome) or without anosmia (n = 5) and SHFM, seven of whom (88%) harbor FGFR1 mutations. Of these seven, one individual is homozygous for p.V429E and six individuals are heterozygous for p.G348R, p.G485R, p.Q594*, p.E670A, p.V688L, or p.L712P. All mutations were predicted by in silico analysis to cause loss of function. Probands with FGFR1 mutations have severe gonadotropin-releasing hormone deficiency (absent puberty and/or cryptorchidism and/or micropenis). SHFM in both hands and feet was observed only in the patient with the homozygous p.V429E mutation; V429 maps to the fibroblast growth factor receptor substrate 2α binding domain of FGFR1, and functional studies of the p.V429E mutation demonstrated that it decreased recruitment and phosphorylation of fibroblast growth factor receptor substrate 2α to FGFR1, thereby resulting in reduced mitogen-activated protein kinase signaling. CONCLUSION: FGFR1 should be prioritized for genetic testing in patients with CHH and SHFM because the likelihood of a mutation increases from 10% in the general CHH population to 88% in these patients.Genet Med 17 8, 651-659.

International STakeholder NETwork (ISTNET): creating a developmental neurotoxicity (DNT) testing road map for regulatory purposes.

A major problem in developmental neurotoxicity (DNT) risk assessment is the lack of toxicological hazard information for most compounds. Therefore, new approaches are being considered to provide adequate experimental data that allow regulatory decisions. This process requires a matching of regulatory needs on the one hand and the opportunities provided by new test systems and methods on the other hand. Alignment of academically and industrially driven assay development with regulatory needs in the field of DNT is a core mission of the International STakeholder NETwork (ISTNET) in DNT testing. The first meeting of ISTNET was held in Zurich on 23-24 January 2014 in order to explore the concept of adverse outcome pathway (AOP) to practical DNT testing. AOPs were considered promising tools to promote test systems development according to regulatory needs. Moreover, the AOP concept was identified as an important guiding principle to assemble predictive integrated testing strategies (ITSs) for DNT. The recommendations on a road map towards AOP-based DNT testing is considered a stepwise approach, operating initially with incomplete AOPs for compound grouping, and focussing on key events of neurodevelopment. Next steps to be considered in follow-up activities are the use of case studies to further apply the AOP concept in regulatory DNT testing, making use of AOP intersections (common key events) for economic development of screening assays, and addressing the transition from qualitative descriptions to quantitative network modelling.

The evolution and distribution of second-hand house prices in Barcelona

The aim of this study is to collect and analyze variables that could have a relationship with the second-hand house prices in Barcelona, as much disaggregated as possible from 2008 to 2011 and make a statistical analysis. The study consists of two parts. The first part is the preliminary study of the data and the second part is the econometric analysis of the data to see if there is any relationship between the second-hand house prices and the variables chosen. Finally, we looked at if there was any atypical observation and if the model presented multicollinarity. With all this information, we extract some conclusions and then, we analyzed more deeply the information.

A Threat to a virtual hand elicits motor cortex activation

We report an experiment where participants observed an attack on their virtual body as experienced in an immersive virtual reality (IVR) system. Participants sat by a table with their right hand resting upon it. In IVR, they saw a virtual table that was registered with the real one, and they had a virtual body that substituted their real body seen from a first person perspective. The virtual right hand was collocated with their real right hand. Event-related brain potentials were recorded in two conditions, one where the participant"s virtual hand was attacked with a knife and a control condition where the knife only struck the virtual table. Significantly greater P450 potentials were obtained in the attack condition confirming our expectations that participants had a strong illusion of the virtual hand being their own, which was also strongly supported by questionnaire responses. Higher levels of subjective virtual hand ownership correlated with larger P450 amplitudes. Mu-rhythm event-related desynchronization in the motor cortex and readiness potential (C3-C4) negativity were clearly observed when the virtual hand was threatened as would be expected, if the real hand was threatened and the participant tried to avoid harm. Our results support the idea that event-related potentials may provide a promising non-subjective measure of virtual embodiment. They also support previous experiments on pain observation and are placed into context of similar experiments and studies of body perception and body ownership within cognitive neuroscience.

Effect of pulps fractionation on formation and strength properties of laboratory hand sheets

The objectives of the work were to study the effect of dewatering time varying on formation properties of papersheets, to determine the role of fines fraction in creation of paper with good formation and strength properties of papersheets, and also to study the effect of charge modification of fibers fractionations on formation properties of handsheets. The paper formation is one of the most important structural properties of paper. This property has effect on physical and optical characteristics of paper. In thi work the effect of formation on tensile strength was determined. The formation properties were analyzed by using the AMBERTEC Beta Formation Tester. The PAM addition as a f;locculant agent did some changes in the formation of paper. Paper sheets were also made from different furnishes of both birch and pine pulps. The fibers particles as a fines have great effect on drainability changes. Fines fraction played important role in papermaking. The two kinds of pulps (pine and birch pulps) were also used in this work for investigation of fines role. As it was expected the fines fraction gave positive effect on paper formation, but when fines fraction was added above initial fines content the formation of paper was deteriorated. The effect of paper formation on tensile strength was also determined. In many cases the poor formation of paper had negative effect on strength properties of paper..

IDENTIFICATION OF SUITABLE AREAS FOR IRRIGATED RICE CROPPING USING MODIS IMAGES AND HAND MODEL

ABSTRACT One of the most relevant activities of Brazilian economy is agriculture. Among the main crops in Brazil, rice is one of high relevance. The state of Rio Grande do Sul, in Southern Brazil, is responsible for 68.7% of domestic production (IBGE, 2013). The goal of this study was to develop a low-cost methodology with a regional scope to identify suitable areas for irrigated rice cropping in this state, using spectro-temporal behavior of vegetation index by means of MODIS images and HAND model. The rice-cropped area of this study was the southern half of the State. Using the HAND model, flood areas were mapped to identify irrigated rice cultivation. We used multi-temporal images of vegetation index from MODIS sensor, covering the period from August 2001 to May 2012. To assess the results, we used data collected in the fields and cropped area information from IBGE. The results showed that the proposed methodology was satisfactory, with Kappa 0.92 and global accuracy of 98.18%. As result, MODIS sensor data and flood areas delineation by means of HAND model generated the estimate irrigated rice area for the area of study.

Yksityisen pysäköinninvalvonnan laintulkinnalliset ongelmat

Tutkielman tavoitteena on paneutua yksityisen pysäköinninvalvonnan lain-tulkinnallisiin ongelmiin Suomessa. Lähtökohtana kysymyksenasettelulle on kansallinen lainsäädäntö, oikeustapaukset, sopimusoikeudelliset peri-aatteet ja oikeuskirjallisuus. Julkinen pysäköinninvalvonta on Suomessa poliisin ja kuntien vastuulla. Suomessa ei ole voimassa yksityistä pysäköinninvalvontaa koskevaa omaa lakia. Yksityisen pysäköinninvalvonnan on nykyisellään katsottu si-sältävän merkittävää julkisen vallan käyttöä, jolloin se tekee siitä perustus-lain vastaista. Samalla yksityinen pysäköinninvalvonta voidaan kuitenkin nähdä sopimukseen perustuvana, laillisena, liiketoimena. Näkökulmien pohdinta tuo esiin laintulkinnallisia ongelmia sekä ongelmia, jotka liittyvät sopimuksen syntymisen kriteereihin.

Sivistyksestä sivilisaatioon. Kulttuurikäsitys J. V. Snellmanin historiallisessa ajattelussa

From Bildung to Civilisation. Conception of Culture in J. V. Snellman’s Historical Thinking The research explores Johan Vilhelm Snellman’s (1806–1881) conception of culture in the context of his historical thinking. Snellman was a Finnish, Swedish-speaking journalist, teacher and thinker, who held a central position in the Finnish national discourse during the nineteenth century. He has been considered as one of the leading theorists of a Finnish nation, writing widely about the themes such as the advancement of the national education, Finnish language and culture. Snellman is already a widely studied person in Finnish intellectual history, often characterised as a follower of G. W. F. Hegel’s philosophical system. My own research introduces a new kind of approach on Snellman’s texts, emphasising the conceptual level of his thought. With this approach, my aim is to broaden the Finnish research tradition on conceptual history. I consider my study as a cultural history of concepts, belonging also to the field of intellectual history. My focus is on one hand on the close reading of Snellman’s texts and on the other hand on contextualising his texts to the European intellectual tradition of the time. A key concept of Snellman’s theoretical thinking is his concept of bildning, which can be considered as a Swedish counterpart of the German concept of Bildung. The Swedish word incorporated all the main elements of the German concept. It could mean education or the so-called high culture, but most fundamentally it was about the self-formation of the individual. This is also the context in which Snellman’s concept of bildning has often been interpreted. In the study, I use the concept of bildning as a starting point of my research but I broaden my focus on the cognate concepts such as culture (kultur), spirit (anda) and civilisation. The purpose of my study is thus to illustrate how Snellman used and modified these concepts and from these observations to draw a conclusion about the nature of his conception of culture. Snellman was an early Finnish philosopher of history but also interested in the practice of the writing of history. He did not write any historical presentations himself but followed the publications in the field of history and introduced European historical writing to the Finnish, Swedish-speaking reading audience in his newspapers. The primary source material consists of different types of Snellman’s texts, including philosophical writings, lecture material, newspaper articles and private letters. I’m reading Snellman’s texts in the context of other texts produced both by his Finnish predecessors and contemporaries and by Swedish, German and French writers. Snellman’s principal philosophical works, Versuch einer spekulativen Entwicklung der Idee der Persönlichkeit (1841) and Läran om staten (1842), were both written abroad. Both of the works were contributions to contemporary debates on the international level, especially in Germany and Sweden. During the 1840s and 1850s Snellman had two newspapers of his own, Saima and Litteraturblad, which were directed towards the Swedish-speaking educated class. Both of the newspapers were very popular and their circulations were among the largest of their day in Finland. The topics of his articles and reviews covered literature, poetry, philosophy and education as well as issues concerning the economic, industrial and technical development in Finland. In his newspapers Snellman not only brought forth his own ideas but also spread the knowledge of European events and ideas to his readers. He followed very carefully the cultural and political situation in Western Europe. He also followed European magazines and newspapers and was well acquainted with German, French and also English literature – and of course Swedish literature to with which he had the closest ties. In his newspapers Snellman wrote countless number of literary reviews and critics, introducing his readers to European literature. The study consists of three main chapters in which I explore my research question in three different, yet overlapping contexts. In the first of these chapters, I analyse Snellman’n theoretical thinking and his concepts of bildning, kultur, anda and civilisation in the context of earlier cultural discourse in Finland as well as the tradition of German idealistic philosophy and neo-humanism. With the Finnish cultural discourse I refer to the early cultural discussion in Finland, which emerged after the year 1809, when Finland became an autonomous entity of its own as a Grand Duchy of Russia. Scholars of the Academy of Turku opened a discussion on the themes such as the state of national consciousness, the need for national education and the development of the Finnish language as a national language of Finland. Many of these academics were also Snellman’s teachers in the early years of his academic career and Snellman clearly formulated his own ideas in the footsteps of these Finnish predecessors. In his theoretical thinking Snellman was a collectivist; according to him an individual should always be understood in connection with the society, its values and manners, as well as to the traditions of a culture where an individual belongs to. In his philosophy of the human spirit Snellman was in many ways a Hegelian but his notion of education or ‘bildning’ includes also elements that connect him with the wider tradition of German intellectual history, namely the neo-humanist tradition and, at least to some extent, to the terminology of J. G. Herder or J. G. Fichte, for example. In this chapter, I also explore Snellman’s theory of history. In his historical thinking Snellman was an idealist, believing in the historical development of the human spirit (Geist in German language). One can characterise his theory of history by stating that it is a mixture of a Hegelian triumph of the spirit and Herderian emphasis on humanity (Humanität) and the relative nature of ‘Bildung’. For Snellman, the process of ‘bildning’ or ‘Bildung’ is being realised in historical development through the actions of human beings. Snellman believed in the historical development of the human civilization. Still Snellman himself considered that he had abandoned Hegel’s idea about the process of world history. Snellman – rightly or wrongly – criticised Hegel of emphasising the universal end of history (the realisation of the freedom of spirit) at the expense of the historical plurality and the freedom of each historical era. Snellman accused Hegel of neglecting the value and independency of different historical cultures and periods by imposing the abstract norm, the fulfilment of the freedom of spirit, as the ultimate goal of history. The historicist in Snellman believed in the individuality of each historical period; each historical era or culture had values, traditions and modes of thought of its own. This historicist in Snellman could not accept the talk about one measure or the end of history. On the other hand Snellman was also a universalist. He believed that mankind had a common task and that task was the development of ‘Bildung’, freedom or humanity. The second main chapter consists of two parts. In the first part, I explore the Finnish nationalistic discourse from the cultural point of view by analysing the notions such as a nation, national spirit or national language and showing how Snellman formulated his own ideas in a dialogic situation, participating in the Finnish discourse but also reacting to international discussions on the themes of the nation and nationality. For Snellman nationality was to a great extent the collective knowledge and customs or practices of the nation. Snellman stated that nationality is to be considered as a form of ‘bildning’. This could be seen not simply as affection for the fatherland but also for the mental identity of the nation, its ways of thinking, its practices, national language, customs and laws, the history of the nation. The simplest definition of nationality that Snellman gives is that nationality is the social life of the people. In the second part of the chapter I exam Snellman’s historical thinking and his understanding about historical development, interaction between different nations and cultures in the course of history, as well as the question of historical change; how do cultures or civilisations develop and who are the creators of culture? Snellman did not believe in one dominating culture but understood the course of history as a dialogue between different cultures. On the other hand, his views are very Eurocentric – here he follows the ideas of Hegel or for example the French historian François Guizot – for Snellman Europe represented the virtue of pluralism; in Europe one could see the diversity of cultures which, on the other hand, were fundamentally based on a common Christian tradition. In the third main chapter, my focus is on the writing of history, more precisely on Snellman’s ideas on the nature of history as a science and on the proper way of writing historical presentations. Snellman wrote critics on the works of history and introduced his readers to the writing of history especially in France, Sweden and German-speaking area – in some extend also in Britain. Snellman’s collectivistic view becomes evident also in his reviews on historical writing. For Snellman history was not about the actions of the states and their heads, nor about the records of ruling families and battles fought. He repeatedly stressed that history is a discipline that seeks to provide a total view of a phenomenon. A historian should not only collect information on historical events, since this information touches only the surface of a certain epoch or civilisation; he has to understand an epoch as totality. This required an understanding about the major contours in history, connections between civilisations and an awareness of significant turning points in historical development. In addition, it required a holistic understanding about a certain culture or historical era, including also the so-called inner life of a specific nation, a common people and their ways of life. Snellman wrote explicitly about ‘cultural history’ in his texts, referring to this kind of broad understanding of a society. In historical writing Snellman found this kind of broader view from the works of the French historians such as François Guizot and Jules Michelet. In all of these chapters, I elaborate the conceptual dimension of Snellman’s historical thinking. In my study I argue that Snellman not only adopted the German concepts of Bildung or Kultur in his own thinking but also developed the Swedish concepts in a way that include personal and innovative aspects. Snellman’s concept of bildning is not only a translation from ‘Bildung’ but he uses the Swedish concept in a versatile way that includes both the moral aspect of human development and social dimension of a human life. Along with ‘bildning’ Snellman used also the terms ‘kultur’ and ‘civilisation’ when referring to the totality of a certain nation or historical era, including both the so-called high culture (arts, science, religion) and the modes of thought as well as ways of life of the people as a whole. Unlike many of his Finnish contemporaries, Snellman did not use civilisation as a negative concept, lacking the moral essence of German term ‘Bildung’ or ‘Kultur’. Instead, for Snellman civilisation was a neutral term and here he comes close to the French tradition of using the term. In the study I argue that Snellman’s conception of culture in fact includes a synthesis of the German tradition of ‘Bildung’ and the French tradition of ‘civilisation’.
