Sensitive Questions in Online Surveys: An Experimental Evaluation of the Randomized Response Technique and the Crosswise Model

Marc Höglinger, Ben Jann & Andreas Diekmann
Self-administered online surveys provide a higher level of privacy protection to respondents than surveys administered by an interviewer. Yet, studies indicate that asking sensitive questions is problematic also in self-administered surveys. Because respondents might not be willing to reveal the truth and provide answers that are subject to social desirability bias, the validity of prevalence estimates of sensitive behaviors from online surveys can be challenged. A well-known method to overcome these problems is the Randomized...

Testing chemical carcinogenicity by using a transcriptomics HepaRG-based model?

Tatyana Y. Doktorova, Reha Yildirimman, Liesbeth Ceelen, Mireia Vilardell, Tamara Vanhaecke, Mathieu Vinken, Gamze Ates, Anja Heymans, Hans Gmuender, Roque Bort, Raffaella Corvi, Pascal Phrakonkham, Ruoya Li, Nicolas Mouchet, Christophe Chesne, Joost Van Delft, Jos Kleinjans, Jose Castell, Ralf Herwig & Vera Rogiers
The EU FP6 project carcinoGENOMICS explored the combination of toxicogenomics and in vitro cell culture models for identifying organotypical genotoxic- and non-genotoxic carcinogen-specific gene signatures. Here the performance of its gene classifier, derived from exposure of metabolically competent human HepaRG cells to prototypical non-carcinogens (10 compounds) and hepatocarcinogens (20 compounds), is reported. Analysis of the data at the gene and the pathway level by using independent biostatistical approaches showed a distinct separation of genotoxic from...

Eco-Enterprises, Policies and Institutional Setup for RHEES - North East India

P. Balachandra, S. Mahapatra, D.C. Baruah, H.N. Chanakya & S. Dasappa
The paper presents a possible approach to address India’s formidable challenge of ensuring security of access to modern energy carriers to the majority of its rural population. This study presents a case study of the selection methodology, implementation strategies for setting up Energy Eco-enterprise in North-East, India under RHEES. The RHEES (Rural Hybrid Energy Enterprise Systems) approach aims at designing and implementing a ‘participatory’ process of capturing the perception of rural end-users on all the...

2012 final report on the performance of the northeast multispecies (groundfish) fishery (May 2012-April 2013).

Tammy Murphy, Andrew W. Kitts, David Records, Chad K. Demarest, Daniel Caless, John Walden & Sharon Benjamin
This report provides an evaluation of the economic and social performance of active limited access Northeast groundfish vessels for the 2012 fishing year (May 2012 through April 2013). Table 1 contains a summary of major trends for the fishery for the period 2009-2012. The report focuses on changes during 2011-2012, with a brief discussion for some performance indicators of trends from 2009 onward. For the first time in its three year history, this annual report...

Ausbreitungsmodellierung von Gerüchen mit zeitaufgelösten Modellen

Peter Boeker, Oliver Wallenfang, Bernd Diekmann & Peter Schulze Lammers
Die Fortschritte der Rechnerentwicklung und neue numerisch-mathematische Verfahren ermöglichen detaillierte Geruchsausbreitungsberechnungen, die viele der bisherigen Einschränkungen vermeiden. Das neue Geruchsausbreitungsmodell basiert auf dem Programmpaket NaSt3D, einem parallelisierten Programmcode der Bonner Angewandten Mathematik, und ist durch spezielle Modifikationen an die Problematik der Geruchsausbreitung angepasst. Mit dem Modell sind zeitaufgelöste Berechnungen möglich, damit kann die für die Geruchswahrnehmung wichtige Frage der Konzentrationsfluktuation ohne modellfremde Hilfsannahmen mitberechnet werden. Durch neue Varianten der Ausbreitungsansätze innerhalb des Modells wird das...

Gefahrenfall und Entempirisierung

David-Christopher Assmann
Die Replik setzt die seit der ersten Ausgabe von Textpraxis geführte Diskussion um eine Neufokussierung der systemtheoretischen Literaturwissenschaft fort. David-Christopher Assmann antwortet auf Oliver Jahraus’ Kritik an der Unterscheidung von Akteuren und Personen im Literatursystem, die jener in Ausgabe #3 in die Debatte eingeführt hat.

VALIDITY AND RELIABILITY OF THE POLISH VERSION OF THE TILBURG FRAILTY INDICATOR (TFI)

I. Uchmanowicz , B. Jankowska-Polańska , B. Uchmanowicz , K. Kowalczuk & R.J.J. Gobbens
Background: In the last decade, studies on frailty have become increasingly frequent in the literature on aging, and also the number of available questionnaires regarding frailty has increased over the years. Therefore, the choice of which questionnaire to use is becoming more difficult. Objective: The aim of this study was to assess the psychometric properties of the Polish version of the Tilburg Frailty Indicator (TFI), an instrument that identifies frailty in the elderly population. Design:...

Disease modelling, biomarkers and virtual physiology - the role of jcpex! and U-CEP

Rainer Von Ammon
The vision of this paper is to bring together a team of biologists and from medicine regarding the definition of biomarkers with specialists of process or event modelling methodology to implement such biomarkers and with IT specialists of Ubiquitous Complex Event Processing of accordant real-time processing platforms for a tremendous vast amount of events or signals per second. In the final paper we will combine and transfer the process modelling approach based on the example...

Social distribution of world wide web use in Romania

Katalin Ravasz
This paper attempts to give a broad picture about the social distribution of the use of the internet, in its first part referring to international aspects, then giving a more detailed account of Romanian peculiarities. The author – Katalin Ravasz – is a sociologist and works with the Institute of Research Programs, Kolozsvár. According to comparative data, the price of a home internet connection is quite high in Romania, but we also have to consider...

The Crack of Dawn

Victor Lamme
There is conscious vision, and there is unconscious visual processing. So far so good. But where lies the boundary between the two? What are the visual functions that shape the transition from “processing in the dark” to having a conscious visual percept? And what are the neural mechanisms that carry that transition? I review the findings on feature detection, object categorization, interference, inference, Gestalt grouping, and perceptual organization, and examine to what extent these functions...

Measuring distinction in the megalithic architecture of the Carnac region: from sign to material

Serge Cassen, Pierre Pétrequin, Christine Boujot, Salvador Domínguez-Bella, Mikaël Guiavarc’h & Guirec Querré
Barely two centuries after the appearance of the first archaeologically- visible elements that served to define the earliest Neolithic in the west of France around 4900 BC – that is, domestic buildings, pottery, a distinctive flint technology, and other aspects of material culture that reproduced the norms that had been established in the Paris Basin and on the middle Loire river – along the southern shores of Brittany there was a sudden and unexpected ‘accumulation...

Neues Dachlabel für nachhaltig erzeugte Lebensmittel

Stephan A. Kolfhaus & Petra Teitscheid
Die Kennzeichnung von Lebensmitteln, auch aus ökologischer Produktion, hat sich immer weiter ausdifferenziert. Durch die Überfülle von Zeichen oder Siegeln kann deren Informationsfunktion für Verbraucher eingeschränkt werden, was zugleich auch für die Transparenz und Vertrauenswürdigkeit dieser Labels Konsequenzen hat. Daher wird im Rahmen einer Fallstudie ein Dachlabel für nachhaltig erzeugte Lebensmittel vorgeschlagen, das im Wesentlichen auf politischen und wissenschaftlichen Vorüberlegungen zum Food-Labeling beruht. Dabei werden im Einzelnen die Merkmale und die Ausgestaltung sowie die besonderen...

The effects of livestock numbers and land cover transformation processes on rangelands in the Balkan Mountains between 1947 and 2012

Hristo Pedashenko, Iva Apostolova & Jens Oldeland
The historical transition from the Bulgarian Kingdom through the Soviet period to the present state of Bulgaria has affected humans and their land use preferences, leading to repeated transformations of the vegetation. We analysed the proportional change of vegetation types in the Tsentralen Balkan National Park in Bulgaria using aerial imagery over the last 65 years and object based image segmentation. Segments were classified into three land cover classes (vegetation types): shrubland, grassland, and shrub-grassland...
