Despite ongoing conceptual, theoretical, and empirical debates, a large number of retrospective self-report scales have been produced to ostensibly measure various classes of such behaviour. These scales are typically based on a variety of theoretical and diagnostic frameworks. Given current conceptual ambiguities, building on previous studies, we evaluated the dimensional structure of 50 scales targeting the assessment of supposedly problematic behaviours in relation to four technologies: Internet, smartphones, video games, and social network sites. We find that two dimensions ('compulsive use' and 'negative outcomes') account for over 50\% of all scale-items analysed. With a median of five dimensions, on average, scales have considered fewer dimensions than various proposed diagnostic criteria and models. No relationships were found between the number of items in a scale and the number of dimensions, or the technology category and the dimensional structure. The findings indicate, firstly, that a majority of scales place an inordinate emphasis on some dimensions over others and, secondly, that despite differences in the items presented, at a dimensional level, there exists a high degree of similarity between scales. These findings highlight shortcomings in existing scales and underscore the need to develop more sophisticated conceptions and empirical tools to understand possible problematic interactions with various digital technologies.}, language = {en} } @inproceedings{Abramova2020, author = {Abramova, Olga}, title = {Does a smile open all doors?}, series = {Proceedings of the 53rd Hawaii International Conference on System Sciences}, booktitle = {Proceedings of the 53rd Hawaii International Conference on System Sciences}, publisher = {HICSS Conference Office University of Hawaii at Manoa}, address = {Honolulu}, isbn = {978-0-9981331-3-3}, pages = {831 -- 840}, year = {2020}, abstract = {Online photographs govern an individual's choices across a variety of contexts.

Evaluation of our theoretical model on a sample of 179 employees reveals a nuanced picture. Self-view engagement while speaking and while listening is positively associated with self-awareness, which, in turn, is negatively associated with satisfaction with meeting process, perceived productivity, and meeting enjoyment.

However, Glg2p possesses an additional tyrosine residue, Tyr230 and therefore two potential autoglucosylation sites. Glucosylation of Glg2p was studied using both matrix-assisted laser desorption ionization and electrospray quadrupole time of flight mass spectrometry. Glg2p, carrying a C-terminal (His(6)) tag, was produced in Escherichia coli and purified. By tryptic digestion and reversed phase chromatography a peptide (residues 219-246 of the complete Glg2p sequence) was isolated that contained 4-25 glucosyl residues. Following incubation of Glg2p with UDPglucose, more than 36 glucosyl residues were covalently bound to this peptide. Using a combination of cyanogen bromide cleavage of the protein backbone, enzymatic hydrolysis of glycosidic bonds and reversed phase chromatography, mono- and diglucosylated peptides having the sequence PNYGYQSSPAM were generated. MS/MS spectra revealed that glucosyl residues were attached to both Tyr232 and Tyr230 within the same peptide. The formation of the highly glucosylated eukaryotic Glg2p did not favour the bacterial glycogen accumulation. Under various experimental conditions Glg2p-producing cells accumulated approximately 30\% less glycogen than a control transformed with a Glg2p lacking plasmid. The size distribution of the glycogen and extractable activities of several glycogen-related enzymes were essentially unchanged. As revealed by high performance anion exchange chromatography, the intracellular maltooligosaccharide pattern of the bacterial cells expressing the functional eukaryotic transgene was significantly altered.

However, this development is not reflected in people's perceptions of wealth inequality, as the public tends to underestimate it. Research suggests that inequality estimates are derived from personal reference groups, which, as we propose, are expanded by social network site (SNS) use. As content on SNSs frequently revolves around events of consumption, signaling enhanced overall population wealth, this study tests the hypothesis that SNS use distorts inequality perceptions downward, i.e., increases the perception of societal equality. Responses of 534 survey participants in the United States confirm that SNS use negatively predicts perceived inequality. The relationship is stronger the more SNS users perceive the content they encounter online as real, supporting the assumption that observing other people's behavior online lowers estimates of nationwide wealth inequality. These findings provide novel insights on inequality misperceptions by suggesting individuals' SNS use as a new predictor of perceived wealth inequality.}, language = {en} } @book{BenRafaelJasperHarris2006, author = {Ben-Rafael, Eliezer and Jasper, Willi and Harris, Paul}, title = {Building a diaspora : Russian Jews in Israel, Germany and the USA}, volume = {13}, publisher = {Brill}, address = {Leiden}, isbn = {978-90-04-15332-5}, pages = {374 S.}, year = {2006}, language = {en} } @incollection{BenderThim2021, author = {Bender, Benedict and Thim, Christof}, title = {Entering complementary markets on software platforms}, series = {Platform coring on digital software platforms}, booktitle = {Platform coring on digital software platforms}, editor = {Bender, Benedict}, publisher = {Springer Gabler}, address = {Wiesbaden}, isbn = {978-3-658-34798-7}, doi = {10.1007/978-3-658-34799-4_7}, pages = {149 -- 199}, year = {2021}, abstract = {Software platforms regularly introduce new features to remain competitive.

In this paper we proceed from the assumption that the role of politics, the constellation of political actors and arenas vary according to the scope and objectives of administrative reforms. Depending on whether they refer to changes between organizational units/levels/sectors ('external institutional policy') or to an internal reorganization ('internal institutional policy'), different actor strategies, patterns of conflict and power constellations can be expected. As external administrative reforms are aimed at changing functional and/or territorial jurisdictions and thus always involve external actors, larger resistance, heavier political conflicts and generally more politicization are likely to occur than in the case of internal administrative reforms. Yet, for internal reforms, too, actor coalitions which support or block institutional changes, promotors, leaders, and moderators have revealed to shape processes and outcomes. Against this background, this chapter examines the influence of politics on various types of administrative reforms making a distinction between external and internal institutional policies. We analyse the role of politico-administrative actors, their strategies and influence on the formulation, trajectories and outcomes of administrative reforms. Our major focus will be on reforms in the multi-level system on the one hand and on (Post-) NPM reforms on the other as two major international trends.

As this paper argues, this is partly due to a concept of terrorism utilized by policymakers, intelligence agents, and police investigators that is based on experience of international terrorism perpetrated by leftists or jihadists as opposed to domestic extreme-right violence. This was one reason why investigators failed to identify the crimes committed by the National Socialist Underground (NSU) in Germany (2000-2011) as extreme-right terrorism, for example. While scholarly debate focused on the Red Army Faction and Al Qaeda, terrorist tendencies among those perpetrating racist and extreme-right violence tended to be disregarded. Influential researchers in the field of "extremism" denied that terrorist acts were committed by right-wingers. By mapping the specifics regarding the strategic use of violence, target selection, addressing of different audiences etc., this paper proposes a more accurate definition of extreme-right terrorism. In comparing it to other forms of terrorism, extreme-right terrorism is distinguished by its specific framework of ideologies and practices, with the underlying idea of an essential inequality that is compensated for through the affirmation of violence.

The analysis involves computational reproducibility checks and robustness assessments. It reveals several patterns. First, we uncover a high rate of fully computationally reproducible results (over 85\%). Second, excluding minor issues like missing packages or broken pathways, we uncover coding errors for about 25\% of studies, with some studies containing multiple errors. Third, we test the robustness of the results to 5,511 re-analyses. We find a robustness reproducibility of about 70\%. Robustness reproducibility rates are relatively higher for re-analyses that introduce new data and lower for re-analyses that change the sample or the definition of the dependent variable. Fourth, 52\% of re-analysis effect size estimates are smaller than the original published estimates and the average statistical significance of a re-analysis is 77\% of the original. Lastly, we rely on six teams of researchers working independently to answer eight additional research questions on the determinants of robustness reproducibility. Most teams find a negative relationship between replicators' experience and reproducibility, while finding no relationship between reproducibility and the provision of intermediate or even raw data combined with the necessary cleaning codes.}, language = {en} } @article{Brosch2004, author = {Brosch, Renate}, title = {Visual Culture}, year = {2004}, language = {en} } @techreport{CaliendoCobbClarkSilvaGoncalvesetal.2023, type = {Working Paper}, author = {Caliendo, Marco and Cobb-Clark, Deborah A. and Silva-Goncalves, Juliana and Uhlendorff, Arne}, title = {Locus of control and the preference for agency}, series = {IZA discussion paper}, volume = {No. 16061}, journal = {IZA discussion paper}, publisher = {Elsevier}, address = {Amsterdam}, issn = {2365-9793}, doi = {10.2139/ssrn.4416820}, pages = {49}, year = {2023}, abstract = {We conduct a laboratory experiment to study how locus of control operates through people's preferences and beliefs to influence their decisions.

Knowing the return and cost of stated effort, principals either retain or delegate the right to make an investment decision that generates payoffs for themselves and their agents. Extending the game to the context in which the return to stated effort is unknown allows us to explicitly study the relationship between locus of control and beliefs about the return to effort. We find that internal locus of control is linked to the preference for agency, an effect that is driven by women.

However, doing so can be difficult as AI encompasses a wide range of technologies, some of which enable fundamentally new forms of interaction. In this research-in-progress paper, we propose the development of a taxonomy to categorize unique characteristics of AI-based technology that influence the interaction and have ethical implications for human workers.

Regarding the definition, an invention is the outcome of a creative process taking place within a technological milieu, which is recognized as successful in terms of its effectiveness as an original technology. In the process of invention, a technological possibility becomes realized. Inventions are distinct from either discovery or innovation. In human creative processes, seven mechanisms of invention can be observed, yielding characteristic outcomes: (1) basic inventions, (2) invention branches, (3) invention combinations, (4) invention toolkits, (5) invention exaptations, (6) invention values, and (7) game-changing inventions. The development of humanity has been strongly shaped by inventions ever since early stone tools and the conception of agriculture. An "explosion of creativity" has been associated with Homo sapiens, and inventions in all fields of human endeavor have followed suit, engendering an exponential growth of cumulative culture. This culture development emerges essentially through a reuse of previous inventions, their revision, amendment and rededication. In sociocultural terms, humans have increasingly regulated processes of invention and invention-reuse through concepts such as intellectual property, patents, open innovation and licensing methods.

Livestock activities are one of the largest producers of residues in the agricultural sector and contribute greatly to climate change. The present chapter gives an introduction and an in-depth analysis of the waste management of livestock for the conversion in a circular agriculture and economy based on research and experience in the sector conducted in the last decades. The conversion of animal waste into energy generation is an opportunity for farmers to obtain additional economic benefits, while contributing to the environment by preventing the release of GHGs into the atmosphere. The use of animal waste for energy generation through anaerobic digestion is a progressive technique and is being widely accepted in Europe, where Germany is the leading country in the use of biogas plants for energy production among others in the European Union. Economically speaking, the livestock industry faces the challenge of converting its production into a clean and more profitable production. The goal of this chapter is to analyze the economic benefit as well as the environmental contribution and future challenges of the use of livestock waste in the biorefineries sector from different perspectives, based on an intensive literature review. This review is accompanied by a geospatial analysis component, mapping biogas reactor hotspots and clusters in Germany, by means of methods of spatial statistics as analysis methods as kernel density estimations (KDE) and K-means clustering, based on volunteer geographic data. The applied methods easily can be transferred to other regions and allow a quick macroscopic overview over existing biogas reactors; furthermore, an identification of cluster and hotspots with a high biogas potential, that in a subsequent step can be analyzed in depth in larger scales.}, language = {en} } @incollection{Dannemann2024, author = {Dannemann, Udo}, title = {Understanding neoliberal subjectification}, series = {Economy, society and politics : socio-economic and political education in schools and universities}, booktitle = {Economy, society and politics : socio-economic and political education in schools and universities}, editor = {Fridrich, Christian and Hagedorn, Udo and Hedtke, Reinhold and Mittnik, Philipp and Tafner, Georg}, publisher = {Springer Fachmedien}, address = {Wiesbaden}, isbn = {978-3-658-42524-1}, doi = {10.1007/978-3-658-42525-8_10}, pages = {217 -- 236}, year = {2024}, abstract = {The contribution explores how an understanding of neoliberal subjectification in socio-economic education can serve to counteract the trend marketisation of democracy.

Other studies have examined what shapes workplace friendships, focusing on determinants such as personality or the spatial composition of organizations. Finally, an increasing number of studies focus on multiplex workplace friendships, where employees who are friends are also linked by a specific work-focused relationship. In this chapter, we first take stock of the literature on workplace friendships by providing an overview of their antecedents and consequences at the individual, the group, and the organizational level, and review the smaller body of research on multiplex workplace friendships. Second, we critically discuss practical implications of workplace friendships, focusing on their relevance to three current challenges for employees and organizations: the increase in virtual work, social inequalities in organizations, and the increased overlap of professional and private life.

Against the background of the continuing expansion of formal education and the persistence of educational and social inequalities, the growing influence of shadow education begs major implications for the postulated goal of equality in educational opportunities. This chapter addresses this issue both theoretically and empirically, focusing on the following question: What is the relationship between the continuous growth of SE across the world and the persistence of social inequality in educational attainment? First, existing findings on the topic are reviewed before I draw on and expand neo-institutionalist and social reproduction theories to incorporate SE, thereby identifying the universal causes for the inevitable expansion of SE and its relation to social inequality across the world. Finally, policy implications and future research directions are discussed. The results of this analysis indicate that even though there exist tremendous differences in the effects of family background on SE use in different regions and systems of education across the world, SE always feeds into the broader institutionalization of education and its role for social stratification. SE might occupy a key role in maintaining vertical and horizontal inequalities in educational attainment in schooled societies, which continue to struggle with inequity of educational opportunities and outcomes in spite of massive educational expansion at the higher education levels and more equity in educational opportunities.}, language = {en} } @article{Ette2012, author = {Ette, Ottmar}, title = {Archeologies of Globalization : European Reflections on Two Phases of Accelerated Globalization in Cornelius de Pauw, Georg Forster, Guillaume-Thomas Raynal and Alexander von Humboldt}, year = {2012}, language = {en} } @article{FaberKonczak2005, author = {Faber, Wolfgang and Konczak, Kathrin}, title = {Strong Equivalence for Logic Programs with Preferences}, year = {2005}, language = {en} } @book{FangXu2005, author = {Fang, Daoyuan and Xu, Jiang}, title = {Asymptotic behavior of solutions to multidimensional nonisentropic hydrodynamic model for semiconductors}, series = {Preprint / Universit{\"a}t Potsdam, Institut f{\"u}r Mathematik, Arbeitsgruppe Partiell}, journal = {Preprint / Universit{\"a}t Potsdam, Institut f{\"u}r Mathematik, Arbeitsgruppe Partiell}, publisher = {Univ.}, address = {Potsdam}, issn = {1437-739X}, pages = {29 S.}, year = {2005}, language = {en} } @article{FanselowKlieglSchlesewsky2008, author = {Fanselow, Gisbert and Kliegl, Reinhold and Schlesewsky, Matthias}, title = {Syntactic variation in German wh-questions}, year = {2008}, language = {en} } @book{Fedosov2006, author = {Fedosov, Boris}, title = {On a spectral theorem for deformation quantization}, series = {Preprint / Universit{\"a}t Potsdam, Institut f{\"u}r Mathematik, Arbeitsgruppe Partiell}, journal = {Preprint / Universit{\"a}t Potsdam, Institut f{\"u}r Mathematik, Arbeitsgruppe Partiell}, publisher = {Univ.}, address = {Potsdam}, issn = {1437-739X}, pages = {19 S.}, year = {2006}, language = {en} } @article{FloeterSelbigSchaub2004, author = {Fl{\"o}ter, Andr{\´e} and Selbig, Joachim and Schaub, Torsten}, title = {Finding metabolic pathways in decision forests}, isbn = {3-540-23221-4}, year = {2004}, language = {en} } @incollection{Franzke2022, author = {Franzke, Jochen}, title = {Challenges of admission and integration of Ukraine war refugees in Germany since the Russian raid in February 2022}, series = {Ziemie Zachodnie i P{\´o}łnocne}, booktitle = {Ziemie Zachodnie i P{\´o}łnocne}, editor = {Stelmach, Andrzej and Barabasz, Adam and Trosiak, Cezary}, publisher = {Uniwersytet im.

Method: By using surface-enhanced laser desorption and ionization time of flight mass spectroscopy (SELDI-TOF-MS) serum peptide and protein patterns were detected enabling to discriminate between postmenopausal women with and without hormone replacement therapy (HRT). Results: Serum of 13 HRT and 27 control subjects was analyzed and 42 peptides and proteins could be tentatively identified based on their molecular weight and binding characteristics on the chip surface. By using decision tree-based Biomarker Patterns (TM) Software classification and regression analysis a discriminatory function was developed allowing to distinguish between HRT women and controls correctly and, thus, yielding a sensitivity of 100\% and a specificity of 100\%. The results show that peptide and protein patterns have the potential to deliver novel biomarkers as well as pinpointing targets for improved treatment. The biomarkers obtained represent a promising tool to discriminate between HRT users and non-users. Conclusion: According to a tentative identification of the markers by their molecular weight and binding characteristics, most of them appear to be part of the inflammation induced acute-phase response.

Furthermore, these assessment procedures are usually only available after the disassembly process has been completed. This is where conceptualization, data acquisition and simulation of remanufacturing processes can help. One major constraining aspect of remanufacturing is reducing logistic efforts, since these also have negative external effects on the environment. Thus regionalization is an additional but in the end consequential challenge for remanufacturing. This article aims to fill a gap by providing an regional remanufacturing approach, in particular the design of local remanufacturing chains.

In a design-science-oriented manner, a prototype of a feedforward ANN is demonstrated and refined using the new learning method. The results show that the so-called crystallizing backpropagation increases the control possibilities of neural structures and interpretation chances, while learning can be carried out as usual.

This study shows the importance of dealing with ANN in hierarchies through backpropagation and brings in learning methods as novel ways of interacting with ANN.
