    Um sein Leistungsangebot den AnsprĂŒchen seiner Mitglieder anzupassen und Optimierungen in der Mitgliederkommunikation vornehmen zu können, gab der Verband Schweizer Fachjournalisten (SFJ AJS) eine Studie am Institut fĂŒr Angewandte Medienwissenschaft (IAM) in Auftrag. Von Interesse waren soziodemographische Daten der Verbandsmitglieder, deren fachjournalistisches Schaffen und die Bewertung der Angebote des SFJ AJS. 910 Aktiv- und Passivmitglieder wurden schriftlich angefragt, einen standardisierten Fragebogen auszufĂŒllen. Die RĂŒcklaufquote belief sich auf rund 33%. Die Auswertung der demographischen Daten zeigt unter den Verbandsmitgliedern eine Dominanz von 55- bis 65-JĂ€hrigen, MĂ€nnern, JournalistInnen mit hohem Ausbildungsstand, die sich zudem ihre journalistischen FĂ€higkeiten "on the job" angeeignet haben. Viele ĂŒben die fachjournalistische Arbeit als Teil des Haupt- oder aber als Nebenberuf aus. FĂŒhrend bei den MĂ€nnern ist die Arbeit im Themenbereich Technik, bei Frauen dominiert der Bereich Kultur. GrundsĂ€tzlich beschĂ€ftigt sich die FachjournalistInnen aber mit mehr als einem Themengebiet. Ihre Arbeit konzentriert sich vorwiegend auf eine bestimmte Sparte und richtet sich an ein ĂŒberregionales Publikum, das sich aus Experten bildet. Dabei bediente ein Fachjournalist in den vergangenen 12 Monaten im Schnitt rund drei journalistische Produkte, wobei die freischaffenden Journalisten hĂ€ufig fĂŒr mehr als drei Medien tĂ€tig waren. Gezeigt werden konnte in der Studie im Weiteren eine wechselseitige Beziehung zwischen Fachjournalismus und dem Gebiet der Public Relations, das auf das Expertenwissen der FachjournalistInnen, aber auch auf deren AbhĂ€ngigkeit von gesicherter Fachinformation zurĂŒckzufĂŒhren ist. Unter den Rollenselbstbildern ist dasjenige des neutralen Berichterstatters und des Experten am beliebtesten, ganz im Gegensatz zum werbemarktorientierten, das kaum Zustimmung fand. Über alle Fachjournalisten gesehen ist der Zeitdruck, der wirtschaftliche Druck und die hohe Arbeitsbelastung, die am stĂ€rksten negativ beurteilten Begleiterscheinungen ihrer Arbeit. Positiv empfunden wurde die Freiheit in der Wahl journalistischer Themen, sowie die Möglichkeit, die eigene Vorstellung von gutem Journalismus realisieren zu können. Zum Verband SFJ AJS fanden die Fachjournalisten vor allem ĂŒber ein anderes Mitglied, Ă€usserst selten ĂŒber Messebesuche oder ĂŒber ein Anschreiben des Verbandes. Die Studie kann dem SFJ AJS eine gesunde Entwicklung attestieren: Immerhin kam ein FĂŒnftel aller Mitglieder in den vergangenen fĂŒnf Jahren neu dazu. Jedoch ist die AffinitĂ€t zum Verband nicht sehr stark, wofĂŒr der tiefe Wissensstand ĂŒber ihn und die spĂ€rlich in Anspruch genommenen Angebote sprechen. Nur der Presseausweis, der Berufsregistereintrag und die Verbandszeitschrift Faximile werden hĂ€ufig genutzt. Zu den StĂ€rken des SFJ AJS wurde seine zuverlĂ€ssige Arbeit, seine fachliche Kompetenz, Mitgliederorientierung und sein sympathisches Wesen gezĂ€hlt, doch fehlt es nach der Meinung der Befragten an Innovation und Dynamik. Ausserdem wird der Einfluss des Verbandes in der Branche als sehr gering angesehen. Die Verbandszeitschrift Faximile wird in der Machart und VerstĂ€ndlichkeit als gut und kompetent bewertet, die inhaltlich berufsrelevanten Informationen gelobt. Der praktische Nutzen und die UnterstĂŒtzung bei der Orientierung im Beruf werden hingegen als gering eingeschĂ€tzt. Als Chance fĂŒr den SFJ AJS kann der stĂ€ndig wachsende Bedarf an Vermittlern von technischen ZusammenhĂ€ngen fĂŒr den Laien angesehen werden. Der Verband muss sich jedoch bewusst sein, dass seine Mitglieder wegen der Doppelfunktion als Experten und Vermittlern oft unter erhöhtem Zeit- und Arbeitsdruck stehen. Eine weitere Schwierigkeit ist zudem die Tatsache, dass der Verband Vertreter aus sehr unterschiedlichen Themengebieten vereint, was es unrealistisch macht, alle Mitglieder gleich gut bedienen zu können

    This study examines the variables of digital maturity of companies. The framework for enterprise architectures Archimate 3.0 is used to compare the variables. The vari¬ables are assigned to the six layers of architecture: Strategy, Business Environment, Applications, Technology, Physical and Implementation and Migration. On the basis of a literature overview, 15 “digital maturity models” with a total of 147 variables are analyzed. The databases Scopus, EBSCO – Business Source Premier and ProQuest are used for this purpose.The results of the work will help researchers and managers to identify which digitiza¬tion variables affect the different layers of the company. This enables researchers or managers to use the right model for a specific purpose or to create a new model from a combination of existing models for the entire company or just one architectural layer.On the basis of a more precise assessment of the digital maturity of a company, better actions can be derived. This work is important for companies, as the digitization of enterprises and markets changed similarly to the invention of the steam engine did. Websites, sensors, mobile devices, apps, etc. are combined into new digital products and services. The competitors in the market have to adapt. If this is not done, they will increasingly disappear.Finally, the authors suggests a conclusion about the current situation regarding the measurement of digital maturity in companies and show in which areas further studies could be carried out

    Vitamin A Metabolism: An Update

    Retinoids are required for maintaining many essential physiological processes in the body, including normal growth and development, normal vision, a healthy immune system, normal reproduction, and healthy skin and barrier functions. In excess of 500 genes are thought to be regulated by retinoic acid. 11-cis-retinal serves as the visual chromophore in vision. The body must acquire retinoid from the diet in order to maintain these essential physiological processes. Retinoid metabolism is complex and involves many different retinoid forms, including retinyl esters, retinol, retinal, retinoic acid and oxidized and conjugated metabolites of both retinol and retinoic acid. In addition, retinoid metabolism involves many carrier proteins and enzymes that are specific to retinoid metabolism, as well as other proteins which may be involved in mediating also triglyceride and/or cholesterol metabolism. This review will focus on recent advances for understanding retinoid metabolism that have taken place in the last ten to fifteen years

    Multi-ancestry genome-wide association analyses improve resolution of genes and pathways influencing lung function and chronic obstructive pulmonary disease risk

    Lung-function impairment underlies chronic obstructive pulmonary disease (COPD) and predicts mortality. In the largest multi-ancestry genome-wide association meta-analysis of lung function to date, comprising 580,869 participants, we identified 1,020 independent association signals implicating 559 genes supported by ≄2 criteria from a systematic variant-to-gene mapping framework. These genes were enriched in 29 pathways. Individual variants showed heterogeneity across ancestries, age and smoking groups, and collectively as a genetic risk score showed strong association with COPD across ancestry groups. We undertook phenome-wide association studies for selected associated variants as well as trait and pathway-specific genetic risk scores to infer possible consequences of intervening in pathways underlying lung function. We highlight new putative causal variants, genes, proteins and pathways, including those targeted by existing drugs. These findings bring us closer to understanding the mechanisms underlying lung function and COPD, and should inform functional genomics experiments and potentially future COPD therapies

    The organization of budgeting processes for ITProjects in Swiss banks is a subject, which is almost unexplored. To gather different budgeting methods and identify actual challenges banks are facing, a thorough literature review was carried out. To find out how the individual budgeting processes of the banks support the ability to react to fast changing market conditions, how they differ from each other as well as to identify the main problems of the budgeting process in place, an interview with five banks have been conducted

    The budgeting processes for IT projects in Swiss banks is a subject which has remained almost unexplored to date. For the purpose of this paper, a thorough literature review was conducted to gather information on different budgeting methods and identify the current challenges that banks are facing. To find out how the various budgeting processes of banks support their ability to react to fast-changing market conditions, how they differ from each other, and to identify the main problems of individual budgeting processes, interviews with five banks were conducted. While, on the whole, Swiss banks were found to be well-prepared for fast changes in the markets, a strong link to their IT project budget processes could not be confirmed. In addition, Swiss banks use traditional budgeting methods in combination with improved budgeting methods. A number of problem areas were identified for current budgeting processes; these include planning accuracy as well as implementation and business IT alignment

    Temperature dependence of magnetization processes in Sm(Co, Fe, Cu, Zr)z magnets with different nanoscale microstructures

    The characteristic microstructure of Sm (Co, Fe, Cu, Zr) z (z = 6.7 - 9.1) alloys with SmCo 5 cell walls in Sm 2 Co 17 cells, all intersected by Zr-rich platelets, makes them some of the best performing high-temperature permanent magnets. Plentiful research has been performed to tailor their microstructure at the nanoscale; but due to its complexity, many questions remain unanswered about the effect of the individual phases on the magnetic performance at different temperatures. Here, we explore this effect for three different Sm (Co, Fe, Cu, Zr) z alloys by deploying high-resolution magnetic imaging via in situ transmission electron microscopy and three-dimensional chemical analysis via atom probe tomography. We show that their microstructures differ in terms of SmCo 5 cell-wall and Z-phase size and density as well as the Cu concentration in the cell walls and demonstrate how these features influence the magnetic domain size and density, thus forming different micromagnetic spin structures. Moreover, we illustrate that the dominant coercivity mechanism at room temperature is domain-wall pinning and show that magnets with a denser cell-wall network, a steeper Cu gradient across the cell-wall boundary, and thinner Z-phase platelets have a higher coercivity. We also show that the coercivity mechanism at high temperatures is domain-wall nucleation at the cell walls. Increasing the Cu concentration inside the cell walls decreases the temperature of transition between pinning and nucleation, significantly decreasing the coercivity with increasing temperature. We, therefore, provide a detailed explanation of how the microstructure on the atomic to nanoscale directly affects the magnetic performance and provide detailed guidelines for an improved design of Sm (Co, Fe, Cu, Zr) z magnets.ISSN:0021-8979ISSN:1089-755
