Deutsch als Wissenschaftssprache, where are you? Einige Bemerkungen zu den Artikelüberschriften in der deutschen Onlinepresse

The role of the German language in scientific communication in Germany has long been the subject of much discussion. In the media, including online, you can find a numerous articles on the subject. Titles in the press show that the German public is very concerned about this state of affairs. The headlines already leave no illusions that the German language is displaced in the scientific research by the English language. Are we dealing with the birth of new lingua franca? Based on selected titles I tried to show how far they correspond with the content of the article. Subjected analyses allowed to discover language strategies used in the titles to illustrate the problem

Women Mentoring Women: A Phenomenological Study

The purpose of this study was to examine the lived experience of ten business and professional women who have experienced a mentoring relationship as a mentor or protegee with another woman, to understand the essence of their mentoring experience, and to know more about their participation as mentors. This study began with the assumption that women who experienced mentoring whether from women or men would be active mentors themselves. However, the data reveal an important contradiction. Since women are entering the business and professional ranks of the work force at an increasing pace, there are greater numbers of women who have reached positions of influence and are in situations to mentor other women. Likewise, there is also an increase in the number of women entering professions who may benefit from a mentoring relationship, especially as it concerns their workplace satisfaction and professional development. Thus, those who promote mentoring need to know more about its practice. This qualitative study took a phenomenological approach to examine mentoring experiences; the data were collected during conversations that developed into narratives. This approach enabled these women participants to reflect deeply on their own mentoring experiences, and to consider how they in turn mentor others. These women narrated their mentoring experiences as they examined the influences of family, education, and gender, as well as their work. Part of this examination considered the historical context which has otherwise been repressive to women\u27s development in general and to their career development in particular for these women aged thirty-eight to fifty-seven. There are two major implications of this study. First, while these women are interested in mentoring, participate in and enjoy mentoring, and recognize the benefits of mentoring, they lack a commitment to specifically mentor other women. Second, this phenomenological methodology promoted their understanding about the way they seem to distance themselves from mentoring even though they believe they benefited from their own mentoring experiences

SOURCES OF VARIATION IN THE CARBON ISOTOPE SIGNATURE OF WINE GRAPE JUICE

The stable carbon isotope ratio (δ13C) – termed “delta c thirteen” – found in grape juice (Vitis vinifera L.) has gained attention as a marker of vine water status. Due to a unique ratio dependent on growing conditions, the δ13C can also be thought of as the grape juice’s “carbon signature.” Some proponents of this measure suggest the carbon signature is dependent wholly on the water status of the vine during ripening, while others state the carbon signature represents seasonal water stress; both theorize the signature may be useful in grower contracts – allowing a winemaker to price, accept, or reject loads dependent on perceived irrigation status. The objectives of this study were first, to explore the potential for water stress, nutrient management, and biotic stress to influence the δ13C of grape juice at harvest. And second, to make a recommendation as to the usefulness of juice δ13C at harvest as a representation of irrigation status throughout the season or solely during ripening. Accomplishing these objectives required leveraging existing field experiments in vineyards across eastern Washington. A drought stress experiment on two cultivars, Cabernet Sauvignon and Riesling, showed juice δ13C at harvest can be influenced by seasonal drought initiated at fruit set. A separate experiment on Cabernet Sauvignon revealed pre-ripening drought can influence the δ13C of berry juice collected in the pre-ripening period, but that influence may be overcome by irrigation during ripening. Third, three mineral nutrition experiments utilizing nitrogen and potassium revealed nitrogen treatments can manipulate δ13C in Syrah juice at harvest. Fourth, two observational experiments – one on the effects of powdery mildew foliar disease severity, the other on grapevine leafroll associated virus-3 positive versus negative vines – showed no difference between treatments in juice δ13C at harvest. Considering results, using the carbon isotope signature in grape juice solely as a marker for either seasonal irrigation practices or irrigation status solely during ripening is against industry interests, as juice δ13C is largely influenced by irrigation during the post-version (ripening) period, but may also be skewed by vineyard nitrogen management

Economic Growth, Greenhouse Gases and Environmental Regulation

Dans cette étude, nous cherchons à mesurer l’impact des émissions anthropogéniques de gaz à effet de serre sur la croissance économique dans un modèle de convergence conditionnelle. Nous nous intéressons au dioxyde de carbone, au méthane, au protoxyde d’azote et au groupe des "gaz F", ainsi qu’à l’effet de la somme de ces polluants, c’est-à-dire la quasi totalité des gaz à effet de serre. Notre échantillon est composé de 81 pays, avec une variété de niveaux de revenu par habitant, entre 1993 et 2012. Nous définissons deux sous-périodes de 10 ans et nous régressons la croissance économique sur la croissance des émissions de chaque polluant séparément, sur le PIB de la première année de la période et sur plusieurs variables de contrôle. Face au risque de biais de causalité inversée entre les émissions de pollution et la croissance économique, et entre l’investissement et la croissance économique, nous décidons d’utiliser les données passées comme variables instrumentales. Plus précisément, les données de la première année de la période sont utilisées comme instruments pour la pollution et l’investissement. Mis à part le CO2, nous trouvons qu’aucun des gaz à effet de serre n’a d’impact significatif sur la croissance économique. La croissance des émissions de CO2 semble avoir un impact positif sur la croissance économique. Cet impact apparaît moins fort sur la seconde période (2003-2012) que sur la première (1993-2002). De plus, il semble plus fort pour la moitié la plus riche des pays de notre échantillon.In this study, we investigate the effect of anthropogenic greenhouse gas emissions on economic growth in a conditional convergence framework. We look at carbon dioxide, methane, nitrous oxide and the group of "F gases", as well as the effect of the sum of these pollutants, i.e. almost all greenhouse gases. Our sample is composed of 81 countries with a variety of per capita income levels and covers the period between 1993 and 2012. We define two ten-year periods and regress economic growth on emissions growth of each pollutant separately, on the first-year GDP of the period and on several control variables. To address the issue of inverse causality bias between pollution emissions and economic growth, as between investment and economic growth, we use an instrumental variable methodology. We use past data to instrument pollution and investment. More precisely, the data of the first year of the period are used as instruments. We find that, except for CO2, greenhouse gas emissions growth does not generate economic growth. CO2 emissions growth has a positive impact on economic growth. Interestingly, this impact is less pronounced between 2003 and 2012, as compared to the 1993-2002 period. In addition, the impact of CO2 emissions growth is stronger in the richer half of countries in our sample

Ocena jakości stron WWW bibliotek państwowych wyższych szkół zawodowych z perspektywy ekologii informacji

The subject of the dissertation is to evaluate the quality of websites. The research consisted in specifying infoecological characteristics and attributes of website quality, diagnosing information needs of users of such services as well as a providing a detailed analysis of 36 library websites of state higher vocational schools in Poland and 6 services of foreign libraries. The main objective of the dissertation is to show and fill in gaps in the field of bibliology and informatology research by emphasizing the particular importance of information ecology as a vital element in the correct website assessment. An indirect goal is to draw attention to a responsibility for the information environment in which web pages play an important role and are treated by the contemporary recipient as one of the main sources of information and knowledge. Methods used to attain the objective of the dissertation included the method of scholarly literature analysis and criticism, and the comparative method. For the purposes of the research an original method was created for assessing the quality of library web services from the perspective of environmental information. The method was built based on the method of diagnostic survey. Results of the analysis of the services have shown their quality level regarding their construction, utility and functionality as well as their information content. The analysis of library websites, their design and content, has led to the conclusion that they meet infoecological information needs of their users, whereby they show infoecological features. The level of the implementation of these features, however, is varied. In an aggregate comparison and statement of the results, it is Polish websites that attained better marks. The ranking of the library website qualities created on the basis of the research performed by the author of the dissertation can be a valuable source of information for the management of a given library. Also, it can serve as a basic set of data that can be used to improve the existing services

Putative P1B-type ATPase from the bacterium Achromobacter xylosoxidans A8 alters Pb2+/Zn2+/Cd2+-resistance and accumulation in Saccharomyces cerevisiae

AbstractPbtA, a putative P1B-type ATPase from the Gram-negative soil bacterium Achromobacter xylosoxidans A8 responsible for Pb2+/Zn2+/Cd2+-resistance in Escherichia coli, was heterologously expressed in Saccharomyces cerevisiae. When present in Zn2+- and Pb2+/Cd2+-hypersensitive S. cerevisiae strains CM137 and DTY168, respectively, PbtA was able to restore Zn2+- and Pb2+-resistant phenotype. At the same time, the increase of Pb, Zn, and Cd accumulation in yeast was observed. However, Cd2+-tolerance of the pbtA-bearing yeasts dramatically decreased. The PbtA-eGFP fusion protein was localized primarily in the tonoplast and also in the plasma membrane and the perinuclear region corresponding to the endoplasmic reticulum at later growth stages. This indicates that PbtA protein is successfully incorporated into membranes in yeasts. Since PbtA caused a substantial increase of Pb2+/Zn2+-resistance and accumulation in baker's yeast, we propose its further use for the genetic modification of suitable plant species in order to obtain an effective tool for the phytoremediation of sites polluted by toxic transition metals

Search for cold and hot gas in the ram pressure stripped Virgo dwarf galaxy IC3418

We present IRAM 30m sensitive upper limits on CO emission in the ram pressure stripped dwarf Virgo galaxy IC3418 and in a few positions covering HII regions in its prominent 17 kpc UV/Ha gas-stripped tail. In the central few arcseconds of the galaxy, we report a possible marginal detection of about 1x10^6 M_sun of molecular gas (assuming a Galactic CO-to-H_2 conversion factor) that could correspond to a surviving nuclear gas reservoir. We estimate that there is less molecular gas in the main body of IC3418, by at least a factor of 20, than would be expected from the pre-quenching UV-based star formation rate assuming the typical gas depletion timescale of 2 Gyr. Given the lack of star formation in the main body, we think the H_2-deficiency is real, although some of it may also arise from a higher CO-to-H_2 factor typical in low-metallicity, low-mass galaxies. The presence of HII regions in the tail of IC3418 suggests that there must be some dense gas; however, only upper limits of < 1x10^6 M_sun were found in the three observed points in the outer tail. This yields an upper limit on the molecular gas content of the whole tail < 1x10^7 M_sun, which is an amount similar to the estimates from the observed star formation rate over the tail. We also present strong upper limits on the X-ray emission of the stripped gas in IC3418 from a new Chandra observation. The measured X-ray luminosity of the IC3418 tail is about 280 times lower than that of ESO 137-001, a spiral galaxy in a more distant cluster with a prominent ram pressure stripped tail. Non-detection of any diffuse X-ray emission in the IC3418 tail may be due to a low gas content in the tail associated with its advanced evolutionary state and/or due to a rather low thermal pressure of the surrounding intra-cluster medium.Comment: 15 pages, 11 figures, A&A accepte

Exemplarische Analyse von Texttiteln im archäologisch-ideologischen Diskurs… zur Ethnogenese der Slawen

Vor Ihnen liegt der Band „Die deutsche Sprache in vielfältigen Forschungsparadigmen”, welcher das Resultat des neunten Linguistischen Doktorandentreffens ist, das in Zusammenarbeit mit den germanistischen Einrichtungen der Universitäten Warschau und Poznań am 9. Mai 2015 an der Universität Łódź stattgefunden hat. An dem Treffen nahmen Doktorandinnen und Doktoranden mit ihren wissenschaftlichen Betreuerinnen und Betreuern teil, die die Universitäten in Warschau, Poznań, Rzeszów, Lublin und Łódź vertreten haben. Sie hatten die Aufgabe, ihre Promotionsprojekte vorzustellen und zu diskutieren, die sie zu verschiedenen Forschungsthemen aus dem Bereich der germanistischen Linguistik ausgearbeitet haben. Die Autorinnen und Autoren konzentrierten sich in ihren Vorträgen auf relevante linguistische Phänomene der deutschen Sprache aus den Bereichen der Morphologie, Textlinguistik, Gesprächsanalyse, Phraseologie, der Hypermedien sowie des Diskurses und der Problematik der Mehrsprachigkeit, die in unterschiedlichen Forschungsparadigmen linguistischen Analysen unterzogen wurden. Die Ergebnisse dieser Analysen finden ihre Widerspiegelung im vorliegenden Band.Dieser Artikel untersucht, unter ausgewählten Aspekten, die Texttitel im archäologisch-ideologischen Diskurs zur Ethnogenese der Slawen. Schon allein die Titelanalyse hat gezeigt, wie stark nicht nur der Inhalt, sondern auch die Form der Texte und somit auch der Titel vom Diskurs, also dem gesellschaftlich-ideologischen Rahmen geprägt wurden. Die Entstehungszeit der Texte war durch Politik und die bereits erwachenden nationalistischen Stimmungen stark geprägt. Auch die Wissenschaft blieb von den Strömungen der Epoche nicht verschont. Der Diskurs zeigt hier seine volle Macht.This article examines, under the selected aspects, the texts’ titles belonging to the archaeological and ideological discourse on ethnogenesis of the Slavs. An analysis of the titles show how much not only the content of the text but also the form of it and the titles themselves are under the historical and institutional framework building up an sociopolitical discourse. The period of time when the title was established is the one of the strong nationalist movement and a particular political situation. As the effect of the latter not only the press releases but also the scientific publications were not neutral against the mention earlier discourse but shows how powerful it was in the case of the titles.Die vorliegende Publikation ist durch die Philologische Fakultät der Universität Łódź und den Verband Stowarzyszenie Nauczycieli Akademickich na rzecz Krzewienia Kultury Języków Europejskich finanziell gefördert worden
