In an attempt to understand the (alarming) character of procrastination, a large body of research on the causes, correlates, and consequences of procrastination has been accumulating over the last 40 years. The aim of this paper is to provide a systematic characterization of the trends in procrastination research and to suggest future directions for research and practice. The systematic characterization comprises a comparison of procrastination to functional forms of delay (referred to as strategic delay) and a presentation of the theoretical approaches to explaining procrastination. The future directions suggested pertain to the development of a differentiated understanding of procrastination and of integral interventions. }}, author = {{Klingsieck, Katrin B.}}, issn = {{1016-9040}}, journal = {{European Psychologist}}, keywords = {{General Psychology, Arts and Humanities (miscellaneous)}}, number = {{1}}, pages = {{24--34}}, publisher = {{Hogrefe Publishing Group}}, title = {{{Procrastination: When Good Things Don’t Come to Those Who Wait}}}, doi = {{10.1027/1016-9040/a000138}}, volume = {{18}}, year = {{2013}}, } @inbook{46948, author = {{Klingsieck, Katrin B. and Steel, Piers}}, booktitle = {{Oxford Bibliographies in Psychology}}, editor = {{Dunn, Dana S. }}, publisher = {{Oxford University Press}}, title = {{{Procrastination}}}, year = {{2013}}, } @article{46939, author = {{Klingsieck, Katrin B.}}, issn = {{1046-1310}}, journal = {{Current Psychology}}, keywords = {{General Psychology}}, number = {{2}}, pages = {{175--185}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Procrastination in Different Life-Domains: Is Procrastination Domain Specific?}}}, doi = {{10.1007/s12144-013-9171-8}}, volume = {{32}}, year = {{2013}}, } @article{46940, author = {{Klingsieck, Katrin B. and Grund, Axel and Schmid, Sebastian and Fries, Stefan}}, issn = {{1543-3382}}, journal = {{Journal of College Student Development}}, keywords = {{Education}}, number = {{4}}, pages = {{397--412}}, publisher = {{Project MUSE}}, title = {{{Why Students Procrastinate: A Qualitative Approach}}}, doi = {{10.1353/csd.2013.0060}}, volume = {{54}}, year = {{2013}}, } @inproceedings{46878, author = {{Güldenpenning, Iris and Schäfer, A and Selig, C and Schack, Thomas}}, booktitle = {{Angewandte Sportpsychologie. 45.

Zur Berechnung der elektromechanischen Charakteristik eines piezoelektrischen ''Energy Harvesters" wird ein auf Materialeigenschaften, Geometrie und Randbedingungen basierendes analytisches Modell vorgestellt. Dieses dient als Basis für ein weiteres Modell, welches den Betrieb eines autonomen Systems beschreibt. Die theoretischen Arbeiten werden mit Laborversuchen validiert. Es zeigt sich, dass der piezoelektrische Harvester im eingeschwungenen Zustand durch den Gleichrichtungsvorgang zwei abwechselnde Lastzustände erfährt. Dies führt zu nichtlinearem Verhalten des Harvesters, besonders wenn die angeschlossene Last eine geringe Impedanz hat. Desweiteren zeigen die Ergebnisse, dass ein solches autonomes System effizient arbeitet, wenn es an eine Last mit hoher Impedanz angeschlossen ist und bei einer der Antiresonanzfrequenz des piezoelektrischen Harvesters entsprechenden Frequenz angeregt wird.Das Modell des autonomen Systems wird auf ein System mit mehreren piezoelektrischen Wandlern erweitert. Zur praktischen Implementierung eines solchen Systems wird eine Technik zur Frequenzeinstellung eingeführt, da die optimalen Betriebsfrequenzen der einzelnen Wandler aufeinander abgestimmt werden müssen. Die Einstellung erfolgt, indem die Entfernung zwischen zwei Permanentmagneten und damit deren Anziehungskraft, welche die Steifigkeit des Harvesters beeinflusst, angepasst wird. Diese Technik zur Frequenzeinstellung wird modelliert und experimentell validiert. Die Ergebnisse zeigen, dass die Frequenzeinstellung mittels Permanentmagneten eine einfache und zugleich effektive Lösung für das Problem der Frequenzanpassung piezoelektrischer ''Energy Harvester" darstellt. Energy harvesters convert ambient energy into useful electrical energy. An analytical model for calculating the electromechanical characteristics of a piezoelectric harvester based on the material properties, geometry and boundary conditions is presented. This model is the basis for a further model which describes the operation of an autonomous system powered by a piezoelectric harvester. This theoretical work is validated by corresponding laboratory experiments. It is found that, in steady-state operation, the piezoelectric harvester experiences two alternating load conditions due to the rectification process. These load conditions make the system behave nonlinearly, especially if the connected electrical load is of low impedance. Furthermore, the results show that such an autonomous system works efficiently if it is connected to a high impedance load and excited at a frequency matching the anti-resonance frequency of the piezoelectric harvester.The model of an autonomous system is extended to describe a system with multiple piezoelectric transducers. For implementing such a system, the optimum operation frequencies of the individual transducers must be adjusted. Therefore, a frequency tuning method is introduced. The tuning is accomplished by adjusting the distance between two permanent magnets and thus changing the attracting force between them in order to affect the structural stiffness of the harvester. This tuning method is modeled and validated experimentally. The results show that frequency tuning using permanent magnets is a simple and effective solution for the frequency adjustment of piezoelectric energy harvesters.}}, author = {{Al-Ashtari, Waleed}}, publisher = {{Shaker}}, title = {{{Model based enhancement of an autonomous system with a piezoelectric harvester}}}, year = {{2013}}, } @article{41354, author = {{Kehne, Miriam and Seifert, Andreas and Schaper, Niclas}}, journal = {{Sportunterricht}}, number = {{2}}, pages = {{53--57}}, title = {{{Struktur eines Instruments zur Kompetenzerfassung in der Sportlehrerausbildung.}}}, volume = {{62}}, year = {{2013}}, } @inbook{44651, author = {{Brandl-Bredenbeck, Hans-Peter and Kämpfe, Astrid and Köster, Carolin}}, booktitle = {{Gesundheitsförderung im Setting Schule }}, editor = {{Marchwacka, M.

The term directive speech act is being used in a more narrow sense than intended by Searle (1975).Dramatic plays are used as data source for the original language and the translation into the other language. The four texts are Brechts “Mutter Courage und Ihre Kinder“, Dürrenmatts „Die Physiker“, Osbornes „Look Back in Anger“, and Leighs „Abigail‘s Party“.The central questions of this study are: Which forms are available in each language? Which specific function does a form fulfill in the system of each language? How do forms correspond across languages?In general, realizations as regular sentences, irregular sentences and non-sentences are possible. In the case of regular sentences, the subcategories imperative, declarative, yes-no interrogative, and wh-interrogative are possible in both languages. German also offers the adhortative and the infinitive. There are remarkable differences in terms of frequencies for these types.In general, German and English behave rather similar in their use of the clause types. The detailed qualitative description of specific examples constitutes the main part of the analysis and answers the following questions: which forms occur as equivalences? Under which conditions can declaratives and interrogatives be used directively?Non-sentences also play an important role. Formal categories, however, are not helpful; hence the utterances were grouped according to functional aspects. These are: propositional content, relationship between speaker and hearer, and illocutionary force.}}, author = {{Freudinger, Markus}}, pages = {{230}}, publisher = {{Universitätsbibliothek Paderborn}}, title = {{{Syntactic perspectives on directive speech acts : a contrastive study}}}, year = {{2013}}, } @inproceedings{528, abstract = {{Cold-boot attacks exploit the fact that DRAM contents are not immediately lost when a PC is powered off. Instead the contents decay rather slowly, in particular if the DRAM chips are cooled to low temperatures.

By exploiting the known cryptographic structure of the cipher and layout of the key data in memory, in our application an AES key schedule with redundancy, the resulting memory image can be searched for sections that could correspond to decayed cryptographic keys; then, the attacker can attempt to reconstruct the original key.
