Basically, closure refers to processes of drawing boundaries, constructing identities, and building communities in order to monopolize scarce resources for one's own group, thereby excluding others from using them. Society is not a homogenous entity but is instead internally structured and subdivided by processes of social closure. Some social formations, such as groups, organizations, or institutions, may be open to everybody, provided they are capable of participation, while access to most others is limited due to certain criteria that either allow people to become members or exclude them from membership. Therefore, social closure is a ubiquitous, everyday phenomenon that can be observed in almost every sphere and place in the social world. Members of societies experience closure from the very beginning of their social life. To be excluded from certain groups starts at school, where presumably homogenous classes begin to subdivide into distinct peer groups or sports teams. Here, exclusion may be rather arbitrary, but the experience of having a door slammed in one's face proceeds in cases, where inclusion depends on formal rules or preconditions. Access to private schools follows explicit rules and depends on financial capacities; access to university depends on a certificate or diploma, eventually from certain schools only; membership in a highly prestigious club depends on economic and social capital and the respective social networks; and finally, in the case of migration, people will have to be eligible for citizenship and pass the thorny path of naturalization. However, it is not just the enormous plurality of forms that makes social closure crucial for sociology. Rather, the process of closure of social relations—of groups, organizations, institutions, and even national societies—is the fundamental process of both "communal" (Vergemeinschaftung) and "associative" relationships (Vergesellschaftung), and neither would be possible without social closure. In this broad and fundamental sense, social closure is not restricted to processes in national societies. It even allows for understanding crucial processes of the way the social world is organized at the regional or global level.}, language = {en} } @article{Guenther2012, author = {G{\"u}nther, Oliver}, title = {More politics in the GI - More GI in politics}, series = {Informatik-Spektrum}, volume = {35}, journal = {Informatik-Spektrum}, number = {6}, doi = {10.1007/s00287-012-0657-9}, pages = {397 -- 398}, year = {2012}, language = {en} } @article{WinklerGoebelBidaultetal.2012, author = {Winkler, Till J. and Goebel, Christoph and Bidault, Francis and G{\"u}nther, Oliver}, title = {Information technology and business practieses in Germany}, series = {The UCLA Anderson Business and Information Technologies (BIT) Project}, journal = {The UCLA Anderson Business and Information Technologies (BIT) Project}, publisher = {world scientific}, address = {Singapore}, doi = {10.1142/9789814390880_0005}, pages = {81 -- 114}, year = {2012}, language = {en} } @article{GuentherBrechtEckhardtetal.2012, author = {G{\"u}nther, Oliver and Brecht, Franziska and Eckhardt, Andreas and Berger, Christian}, title = {Corporate career presences on social network sites: an analysis of hedonic and utilitarian value}, series = {CHI '12 Proceedings of the SIGCHI Conference on Human Factors in Computing Systems}, journal = {CHI '12 Proceedings of the SIGCHI Conference on Human Factors in Computing Systems}, publisher = {ACM}, address = {Texas}, isbn = {978-1-4503-1015-4}, doi = {10.1145/2207676.2208408}, pages = {2441 -- 2450}, year = {2012}, abstract = {Due to the shortage of skilled workforce and the increasing usage of social network sites, companies increasingly apply social network sites to attract potential applicants.

The ability to extract such information however, has been restricted by a limited understanding of the relationships between minerals and the environment. In an attempt to fill in this gap in our knowledge, 146 surface sediment samples have been investigated from 146 lakes on the Tibetan Plateau. The mineral compositions derived from these samples by X-Ray Diffraction (XRD) were used to examine the relationships between mineral compositions and the environmental variables determined for each site. Statistical techniques including Multivariate regression trees (MRT) and Redundancy Analysis (RDA), based on the mineral spectra and environmental variables, reveal that the electrical conductivity (EC) and Mg/Ca ratios of lake water are the most important controls on the composition of endogenic minerals. No endogenic minerals precipitate under hyper-fresh water conditions (EC lower than 0.13 mS/cm), with calcite commonly forming in water with EC values above 0.13 mS/cm. Between EC values of 0.13 and 26 mS/cm the mineral composition of lake sediments can be explained in terms of variations in the Mg/Ca ratio: calcite dominates at Mg/Ca ratios of less than 33, whereas aragonite commonly forms when the ratio is greater than 33. Where EC values are between 26 and 39 mS/cm, monohydrocalcite precipitates together with calcite and aragonite; above 39 mS/cm, gypsum and halite commonly form. Information on the local geological strata indicates that allogenic (detrital) mineral compositions are primarily influenced by the bedrock compositions within the catchment area. By applying these relationships to the late glacial and Holocene mineral record from Chaka Salt Lake, five lake stages have been identified and their associated EC conditions inferred. The lake evolved from a freshwater lake during the late glacial (before 11.4 cal. ka BP) represented by the lowest EC values (< 0.13 mS/cm), to a saline lake with EC values slightly higher than 39 mS/cm during the early and mid Holocene (ca. 11.4-5.3 cal. ka BP), and finally to a salt lake (after 5.3 cal. ka BP). These results illustrate the utility of our mineral-environmental model for the quantitative reconstruction of past environmental conditions from lake sediment records.}, language = {en} } @article{HildebrandtGeissler2012, author = {Hildebrandt, Niko and Geissler, Daniel}, title = {Semiconductor quantum dots as FRET acceptors for multiplexed diagnostics and molecular ruler application}, series = {Advances in Experimental Medicine and Biology}, volume = {733}, journal = {Advances in Experimental Medicine and Biology}, editor = {Zahavy, E and Ordentlich, A and Yitzhaki, S and Shafferman, A}, publisher = {Springer}, address = {Dordrecht}, isbn = {978-94-007-2554-6}, issn = {0065-2598}, doi = {10.1007/978-94-007-2555-3_8}, pages = {75 -- 86}, year = {2012}, abstract = {Applications based on Forster resonance energy transfer (FRET) play an important role for the determination of concentrations and distances within nanometer-scale systems in vitro and in vivo in many fields of biotechnology.

Moreover, investigations with American-English- and Dutch-learning infants suggest that processing prosodic boundary markings involves a weighting of these cues. This weighting seems to develop with increasing exposure to the native language and to underlie crosslinguistic variation. In the following, we report the results of four experiments using the headturn preference procedure to explore the perception of prosodic boundary cues in German infants. We presented 8-month-old infants with a sequence of names in two different prosodic groupings, with or without boundary markers. Infants discriminated both sequences when the boundary was marked by all three cues (Experiment 1) and when it was marked by a pitch change and preboundary lengthening in combination (Experiment 2). The presence of a pitch change (Experiment 3) or preboundary lengthening (Experiment 4) as single cues did not lead to a successful discrimination. Our results indicate that pause is not a necessary cue for German infants. Pitch change and preboundary lengthening in combination, but not as single cues, are sufficient. Hence, by 8 months infants only rely on a convergence of boundary markers. Comparisons with adults' performance on the same stimulus materials suggest that the pattern observed with the 8-month-olds is already consistent with that of adults. We discuss our findings with respect to crosslinguistic variation and the development of a language-specific prosodic cue weighting.}, language = {en} } @article{HenrichsElsnerElsneretal.2012, author = {Henrichs, Ivanina and Elsner, Claudia and Elsner, Birgit and Gredeback, Gustaf}, title = {Goal salience affects infants' goal-directed gaze shifts}, series = {Frontiers in psychology}, volume = {3}, journal = {Frontiers in psychology}, publisher = {Frontiers Research Foundation}, address = {Lausanne}, issn = {1664-1078}, doi = {10.3389/fpsyg.2012.00391}, pages = {7}, year = {2012}, abstract = {Around their first year of life, infants are able to anticipate the goal of others' ongoing actions. For instance, 12-month-olds anticipate the goal of everyday feeding actions and manual actions such as reaching and grasping. However, little is known whether the salience of the goal influences infants' online assessment of others' actions. The aim of the current eye-tracking study was to elucidate infants' ability to anticipate reaching actions depending on the visual salience of the goal object. In Experiment 1, 12-month-old infants' goal-directed gaze shifts were recorded as they observed a hand reaching for and grasping either a large (high-salience condition) or a small (low-salience condition) goal object. Infants exhibited predictive gaze shifts significantly earlier when the observed hand reached for the large goal object compared to when it reached for the small goal object. In addition, findings revealed rapid learning over the course of trials in the high-salience condition and no learning in the low-salience condition. Experiment 2 demonstrated that the results could not be simply attributed to the different grip aperture of the hand used when reaching for small and large objects. Together, our data indicate that by the end of their first year of life, infants rely on information about the goal salience to make inferences about the action goal.}, language = {en} }
