Work and health : remodelling perspectives of working life research, as proposed by Järvholm et al. (2009)

Järvholm and Co-workers (2009) proposed a conceptual model for research on working life. Models are powerful communication and decision tools. This model is strongly unidirectional and does not cover the mentioned interactions in the arguments.With help of a genealogy of work and of health it is shown that work and health are interactive and have to be analysed on the background of society.Key words: research model, work, health, occupational health, society, interaction, discussion paperRemodellierung der von Järvholm et al. (2009) vorgeschlagenen Forschungsperspektiven in Arbeit und GesundheitJärvholm und Kollegen stellten 2009 ein konzeptionelles Modell für die Forschung im Bereich Arbeit und Gesundheit vor. Modelle stellen kraftvolle Kommunikations- und Entscheidungsinstrumente dar. Die Einflussfaktoren im Modell verlaufen jedoch nur in einer Richtung und bilden die interaktiven Argumente im Text nicht ab. Mit Hilfe einer Genealogie der Begriffe Arbeit und Gesundheit wird aufgezeigt, dass Arbeit und Gesundheit sich gegenseitig beeinflussen und nur vor dem Hintergrund der jeweiligen gesellschaftlichen Kontextfaktoren zu analysieren sind.Introduction : After an interesting introduction about the objectives of research on working life, Järvholm and Co-workers (2009) manage to define a conceptual model for working life research out of a small survey of Occupational Safety and Health (OSH) definitions. The strong point of their model is the entity 'working life' including personal development, as well as career paths and aging. Yet, the model Järvholm et al. (2009) propose is strangely unidirectional; the arrows point from the population to working life, from there to health and to disease, as well as to productivity and economic resources. The diagram only shows one feed-back loop: between economic resources and health. We all know that having a chronic disease condition influences work and working capacity. Economic resources have a strong influence on work, too. Having personal economic resources will influence the kind of work someone accepts and facilitate access to continuous professional education. A third observation is that society is not present in the model, although this is less the case in the arguments. In fact, there is an incomprehensible gap between the arguments brought forth by Järvholm and co-workers and their reductionist model.Switzerland has a very low coverage of occupational health specialists. Switzerland is a long way from fulfilling the WHO's recommendations on workers' access to OSH services as described in its Global plan of action. The Institute for Work and Health (IST) in Lausanne is the only organisation which covers the major domains of OSH research that are occupational medicine, occupational hygiene, ergonomic and psychosocial research. As the country's sole occupational health institution we are forced to reflect the objectives of working life research so as not to waste the scare resources available.I will set out below a much shortened genealogy of work and of health, with the aim of extending Järvholm et al's (2009) analyses on the perspectives of working life research in two directions. Firstly towards the interactive nature of work and health and the integration of society, and secondly towards the question of what working life means or where working life could be situated.Work, as we know it today - paid work regulated by a contract as the basis for sustaining life and as a base for social rights - was born in modern era. Therefore I will start my genealogy in the pre-modern era, focus on the important changes that occurred during industrial revolution and the modern era and end in 2010 taking into account the enormous transformations of the past 20-30 years. I will put aside some 810 years of advances in science and technology that have expanded the world's limits and human understanding, and restrict my genealogy to work and to health/body implicating also the societal realm.

Le corps humain et la conceptualisation de l'espace sacré: trois exemples tirés des traditions indiennes

(Résumé de l'ouvrage) Carte geografiche ma anche riti, concetti cosmologici, fonti letterarie vengono riletti in quanto modelli di organizzazione spaziale in determinati sistemi simbolici religiosi: la presente raccolta sviluppa la problematica della cartografia religiosa in tradizioni del mondo antico, indiane, sudest asiatiche, islamiche e occidentali contemporanee. Geographische Karten, aber auch Rituale, kosmologische Konzepte und literarische Quellen werden als Modelle räumlicher Organisation in bestimmten religiösen Symbolsystemen untersucht. Der vorliegende Sammelband behandelt diese Themenbereiche mit Beiträgen zur Antike, zu Indien, Südostasien, zum Islam und zu zeitgenössischen Bewegungen im Westen.

Comparative descriptions of eggs from three species of Rhodnius (Hemiptera: Reduviidae: Triatominae)

The authors describe and compare the morphological and ultrastructural characteristics of eggs from the three most recent described species of the genus Rhodnius Stål, 1859, which have not previously been studied. These species are Rhodnius colombiensis (Mejia, Galvão & Jurberg 1999), Rhodnius milesi (Carcavallo, Rocha, Galvão & Jurberg 2001) and Rhodnius stali (Lent, Jurberg & Galvão 1993). The results revealed that there are similarities in the exochorial architecture of optical microscopy and scanning electron microscopy; these include the predominance of hexagonal cells that are common to all Rhodnius species and variable degrees of lateral flattening, which is common not only to species of this genus, but also to the Rhodniini tribe. Differences in overall colour, the presence of a collar in R. milesi, a longitudinal bevel in R. stali and the precise length of R. colombiensis can be useful distinguishing features. As a result of this study, the key for egg identification proposed by Barata in 1981 can be updated.

Zwischen Literatur und Journalismus : die Reportagen und Feuilletons von Annemarie Schwarzenbach

Die Dissertation bietet eine neue Sichtweise auf die Autorin Annemarie Schwarzenbach, die in den 1930er Jahren im Feuilleton der renommiertesten Schweizer Zeitungen - wie der NZZ, der Weltwoche oder auf den besten Doppelseiten der illustrierten Zeitschriften - überaus präsent war. Im Zentrum der Analyse steht das journalistische Werk Schwarzenbachs mit ca. 300 Reportagen und Feuilletons, die im Zeitraum von 1930-1942 erschienen sind. Die Studie erlaubt einen Einblick in wenig erforschtes und zum Teil unveröffentlichtes Material, das in den für Schwarzenbach relevanten Nachlässen und Zeitungsarchiven in großen Schweizer Bibliotheken ausgewertet wurde. Zu den konsultierten Institutionen gehören die Schweizerische Nationalbibliothek (NB) in Bern, das Schweizerische Literaturarchiv (SLA), das Robert Walser-Zentrum in Bern, die Zentralbibliothek Zürich (ZBZ) und die Universitätsbibliothek Basel (UB Basel). Zu den ausgewerteten Beständen zählen die Zürcher Illustrierte, Sie und Er, Annabelle, die Basler National-Zeitung, Die Tat, Luzerner Tagblatt, Thurgauer Zeitung, Die Weltwoche und ABC. Erst die Arbeit an den Originalartikeln in den Zeitungen ermöglicht präzise Aussagen zum Aufbau und Stil der Texte; das impliziert die Untersuchung der einzelnen Textstufen - vom Typoskript bis zum gedruckten Artikel. Das publizistische Profil der Zeitungen wurde analysiert und in Beziehung zu den jeweiligen Beiträgen Schwarzenbachs gesetzt. Die Arbeit ist als Text- Kontext-Studie angelegt. Das Projekt veranschaulicht die Entwicklung einer Schriftstellerin, die in ihren literarischen Anfangen eher einem poetologischen Prinzip folgt, das sich klassische Modelle der dichterischen , Inspiration' zum Vorbild nimmt und sich an zeitgenössischen Dichtern wie Rilke und George orientiert. Über das Medium der Zeitung findet die Autorin zu einem neuen Stil: Im Spannungsfeld von subjektiv-lyrischem Anspruch und der Orientierung am Sachlichkeitswert und Authentizitätspostulat entstehen Schwarzenbachs journalistische Arbeiten. In dieser Hinsicht ist die Autorin keine literarische Außenseiterin, trotz ihrer außergewöhnlichen Biografie und Lebenssituation. Sie teilt in ihrer Hinwendung zum feuilletonistischen und journalistischen Schreiben die literarischen Existenzbedingungen einer ganzen Generation von Grenzgängern zwischen Literatur und Journalismus, von Musil, Roth bis zu Kerr, Kisch, Toller und Benjamin. Annemarie Schwarzenbach akzentuiert aber dabei die Reportage als Medium der Fremderfahrung und fuhrt sie gleichzeitig an ihren historischen Ursprung im Reisebericht zurück.

Shocks and institutions in a job matching model

This paper explains the divergent behavior of European an US unemploymentrates using a job market matching model of the labor market with aninteraction between shocks an institutions. It shows that a reduction inTF growth rates, an increase in real interest rates, and an increase intax rates leads to a permanent increase in unemployment rates when thereplacement rates or initial tax rates are high, while no increase inunemployment occurs when institutions are "employment friendly". The paperalso shows that an increase in turbulence, modelle as an increase probabilityof skill loss, is not a robust explanation for the European unemploymentpuzzle in the context of a matching model with both endogenous job creationand job estruction.

Bioactivity of the latex from Parahancornia amapa (Apocynaceae) on the development of Rhodnius nasutus (Hemiptera, Reduviidae, Triatominae) under laboratory conditions

Bioactivity of the latex from Parahancornia amapa (Apocynaceae) on the development of Rhodnius nasutus (Hemiptera, Reduviidae, Triatominae) under laboratory conditions. The aim of this study was to verify the effects of the methanolic fraction of the latex from Parahancornia amapa (Apocynaceae) (PALAM) on individuals of the species Rhodnius nasutus Stål (Hemiptera, Triatominae). Many of the insects treated with the substance presented deformities and these may interfere in the feeding and possibly hinder the reproductive capacity. They also presented significant mortality during the molt when compared to the control group, noting a gradual increase in mortality. The treated insects also presented delayed nymphal development (5th instar) and higher adult longevity.

Efeito do peso corporal na fecundidade e na longevidade do percevejo predador Podisus rostralis

Considerando a importância dos percevejos predadores como agentes de controle biológico e a necessidade de se otimizar sua produção massal, realizou-se o presente trabalho para avaliar a influência do peso corporal sobre a sobrevivência e a reprodução de fêmeas de Podisus rostralis (Stål) (Hemiptera: Pentatomidae). Os tratamentos foram constituídos por fêmeas desse predador com peso médio de: 39,5 mg, 45,5 mg, 51,5 mg, 57,5 mg e 63,5 mg. O período de preoviposição foi menor nas fêmeas mais pesadas, enquanto o número de ovos e de ninfas por dia apresentou relação linear positiva com o peso das fêmeas de P. rostralis. A longevidade das fêmeas desse predador foi semelhante entre tratamentos, porém não apresentou tendência de variação em razão do seu peso corporal. Como o objetivo de uma criação massal é produzir o maior número possível de ninfas por dia, recomenda-se o uso de fêmeas de P. rostralis com peso acima de 60,0 mg.

Letramento em química, educação planetária e inclusão social

From the different conceptions on scientific and technology literacy (STL), and reflections on globalization and social inclusion, this paper points out the responsibility of the chemists in social actions by their associations for supporting political actions to improving the quality of life, and to protecting the environment by sustainable development for changing the modern society. Supporting ideas for equity within the society between the nations, and giving examples from approaching of socioscientific issues of the textbook "Chemistry and Society", it demonstrated the role of the teachers and the chemistry professionals to realize the STL of the people in the planetary perspective.

Influence of the temperature and type of salt on the phase equilibrium of peg 1500 + potassium phosphate and peg 1500 + sodium citrate aqueous two-phase systems

The present work analyzed the effect of the temperature and type of salt on the phase equilibrium of aqueous two-phase systems (ATPS) formed by poly (ethylene glycol) (PEG) 1500 + potassium phosphate, from (278.15 to 318.15) K, and PEG 1500 + sodium citrate, from (278.15 to 298.15) K. The rise of the temperature normally increased the slope of the tie line (STL). With respect to the influence of the type of salt, sodium citrate showed better capability to induce phase separation, when compared to potassium phosphate.
