In dieser Debatte wird Honneth dahingehend kritisiert, dass es ihm mit seiner kritischen Gesellschaftstheorie entgegen seiner eigenen systematischen Zielsetzung nicht gelingt, in modernen liberaldemokratischen Gesellschaften s{\"a}mtliche Ph{\"a}nomene von sozialer Herrschaft kritisch zu hinterfragen. Denn soziale Anerkennung, die Honneth als Schl{\"u}sselbegriff f{\"u}r diese kritische Hinterfragung behandelt, bei der soziale Herrschaft in Verbindung mit sozialer Missachtung (als mangelnde soziale Anerkennung) steht, kann laut der Kritik faktisch selbst ein Medium f{\"u}r die Stiftung von sozialer Unterwerfung sein. Dies geschieht in Prozessen von Identit{\"a}tsentwicklung, in denen soziale Anerkennung f{\"u}r Individuen als Anerkannte bestimmte Identit{\"a}tsm{\"o}glichkeiten einr{\"a}umt und auf diese Weise gleichzeitig andere Identit{\"a}tsm{\"o}glichkeiten ausschließt, womit sie auf diese Identit{\"a}t einschr{\"a}nkend und insofern herrschend wirkt. Es handelt sich um eine Form von sozialer Herrschaft, die durch soziale Anerkennung gestiftet wird. Honneth zieht dem Vorwurf zufolge nicht in Erw{\"a}gung, dass soziale Anerkennung bei Individuen als Anerkannte einen solchen negativen Effekt erzielen kann. Hieraus ergeben sich die Fragen, ob soziale Anerkennung in Prozessen von Identit{\"a}tsentwicklung jeweils mit sozialer Herrschaft einhergeht und wie dieser Typus von sozialer Herrschaft kritisiert werden kann. Diese Fragen hat Honneth zuletzt in einem pers{\"o}nlichen Gespr{\"a}ch mit Allen und Cooke (als zwei Teilnehmerinnen der Debatte gegen Honneth) beantwortet. An dieser Stelle vertritt er mit beiden Gespr{\"a}chsteilnehmerinnen die Auffassung, dass die Operation der Einschr{\"a}nkung von Identit{\"a}tsm{\"o}glichkeiten an sich keine Operation darstellt, welche, wie sonst in der Debatte gegen seine kritische Gesellschaftstheorie behauptet wird, auf soziale Herrschaft zur{\"u}ckf{\"u}hrt. Diese Auffassung beruht auf der Idee, wonach soziale Anerkennung sich in jenem praktischen Kontext nur unter der Bedingung als herrschaftsstiftend erweist, dass sie immanente Prinzipien verletzt, die substanziell kritische Maßst{\"a}be definieren. Mein Beitrag zu dieser Debatte gegen Honneth besteht auf der einen Seite in der Erkl{\"a}rung, dass sowohl jene Auffassung als auch jene Idee argumentativ mangelhaft sind, und auf der anderen Seite in der Ausf{\"u}hrung des Vorhabens, diesen argumentativen Mangel selbst zu beheben. Gegen jene Auffassung behaupte ich, dass die drei Autoren in ihrem Gespr{\"a}ch nicht erl{\"a}utern, inwiefern soziale Anerkennung nicht herrschend wirkt, wenn sie die Identit{\"a}tsm{\"o}glichkeiten von Individuen als Anerkannte einschr{\"a}nkt, denn mit dieser Einschr{\"a}nkung wird vielmehr faktisch {\"u}ber diese Individuen geherrscht - die Debatte gegen Honneth, so zur Unterst{\"u}tzung dieser Ansicht, baut haupts{\"a}chlich auf ebendiesem Faktum auf. Gegen jene Idee habe ich f{\"u}nf problematische Fragen gestellt und beantwortet, die Bezug eigentlich nicht allein auf diese Idee selbst, sondern {\"u}berdies auf weitere, naheliegende Ideen nehmen, welche die drei Autoren angesprochen haben.}, language = {de} } @misc{SchaeferBittmann2018, author = {Schaefer, Laura and Bittmann, Frank}, title = {Coherent behavior of neuromuscular oscillations between isometrically interacting subjects}, series = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, number = {480}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-419864}, pages = {10}, year = {2018}, abstract = {Previous research has shown that electrical muscle activity is able to synchronize between muscles of one subject. The ability to synchronize the mechanical muscle oscillations measured by Mechanomyography (MMG) is not described sufficiently. Likewise, the behavior of myofascial oscillations was not considered yet during muscular interaction of two human subjects. The purpose of this study is to investigate the myofascial oscillations intra- and interpersonally. For this the mechanical muscle oscillations of the triceps and the abdominal external oblique muscles were measured by MMG and the triceps tendon was measured by mechanotendography (MTG) during isometric interaction of two subjects (n = 20) performed at 80\% of the MVC using their arm extensors. The coherence of MMG/MTG-signals was analyzed with coherence wavelet transform and was compared with randomly matched signal pairs. Each signal pairing shows significant coherent behavior. Averagely, the coherent phases of n = 485 real pairings last over 82 ± 39 \% of the total duration time of the isometric interaction. Coherent phases of randomly matched signal pairs take 21 ± 12 \% of the total duration time (n = 39). The difference between real vs. randomly matched pairs is significant (U = 113.0, p = 0.000, r = 0.73). The results show that the neuromuscular system seems to be able to synchronize to another neuromuscular system during muscular interaction and generate a coherent behavior of the mechanical muscular oscillations. Potential explanatory approaches are discussed.}, language = {en} } @misc{ZghalColsonBlainetal.2019, author = {Zghal, Firas and Colson, Serge S. and Blain, Gr{\´e}gory and Behm, David George and Granacher, Urs and Chaouachi, Anis}, title = {Combined Resistance and Plyometric Training Is More Effective Than Plyometric Training Alone for Improving Physical Fitness of Pubertal Soccer Players}, series = {Postprints der Universit{\"a}t Potsdam Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam Humanwissenschaftliche Reihe}, number = {576}, issn = {1866-8364}, doi = {10.25932/publishup-43781}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-437810}, pages = {12}, year = {2019}, abstract = {The purpose of this study was to compare the effects of combined resistance and plyometric/sprint training with plyometric/sprint training or typical soccer training alone on muscle strength and power, speed, change-of-direction ability in young soccer players. Thirty-one young (14.5 ± 0.52 years; tanner stage 3-4) soccer players were randomly assigned to either a combined- (COMB, n = 14), plyometric-training (PLYO, n = 9) or an active control group (CONT, n = 8). Two training sessions were added to the regular soccer training consisting of one session of light-load high-velocity resistance exercises combined with one session of plyometric/sprint training (COMB), two sessions of plyometric/sprint training (PLYO) or two soccer training sessions (CONT). Training volume was similar between the experimental groups. Before and after 7-weeks of training, peak torque, as well as absolute and relative (normalized to torque; RTDr) rate of torque development (RTD) during maximal voluntary isometric contraction of the knee extensors (KE) were monitored at time intervals from the onset of contraction to 200 ms. Jump height, sprinting speed at 5, 10, 20-m and change-of-direction ability performances were also assessed. There were no significant between-group baseline differences. Both COMB and PLYO significantly increased their jump height (Δ14.3\%; ES = 0.94; Δ12.1\%; ES = 0.54, respectively) and RTD at mid to late phases but with greater within effect sizes in COMB in comparison with PLYO. However, significant increases in peak torque (Δ16.9\%; p < 0.001; ES = 0.58), RTD (Δ44.3\%; ES = 0.71), RTDr (Δ27.3\%; ES = 0.62) and sprint performance at 5-m (Δ-4.7\%; p < 0.001; ES = 0.73) were found in COMB without any significant pre-to-post change in PLYO and CONT groups. Our results suggest that COMB is more effective than PLYO or CONT for enhancing strength, sprint and jump performances.}, language = {en} } @misc{Wegmann2022, author = {Wegmann, Simone}, title = {Policy-making power of opposition players}, series = {Zweitver{\"o}ffentlichungen der Universit{\"a}t Potsdam : Wirtschafts- und Sozialwissenschaftliche Reihe}, journal = {Zweitver{\"o}ffentlichungen der Universit{\"a}t Potsdam : Wirtschafts- und Sozialwissenschaftliche Reihe}, number = {1}, issn = {1867-5808}, doi = {10.25932/publishup-56651}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-566516}, pages = {27}, year = {2022}, abstract = {The organisation of legislative chambers and the consequences of parliamentary procedures have been among the most prominent research questions in legislative studies. Even though democratic elections not only lead to the formation of a government but also result in an opposition, the literature has mostly neglected oppositions and their role in legislative chambers. This paper proposes to fill this gap by looking at the legislative organisation from the perspective of opposition players. The paper focuses on the potential influence of opposition players in the policy-making process and presents data on more than 50 legislative chambers. The paper shows considerable variance of the formal power granted to opposition players. Furthermore, the degree of institutionalisation of opposition rights is connected to electoral systems and not necessarily correlated with other institutional characteristics such as regime type or the size of legislative chambers.}, language = {en} } @misc{PrieskeMaffiulettiGranacher2018, author = {Prieske, Olaf and Maffiuletti, Nicola A. and Granacher, Urs}, title = {Postactivation Potentiation of the Plantar Flexors Does Not Directly Translate to Jump Performance in Female Elite Young Soccer Players}, series = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, number = {483}, issn = {1866-8364}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-420558}, pages = {10}, year = {2018}, abstract = {Background: Infection with human immunodeficiency virus (HIV) affects muscle mass, altering independent activities of people living with HIV (PLWH). Resistance training alone (RT) or combined with aerobic exercise (AE) is linked to improved muscle mass and strength maintenance in PLWH. These exercise benefits have been the focus of different meta-analyses, although only a limited number of studies have been identified up to the year 2013/4. An up-to-date systematic review and meta-analysis concerning the effect of RT alone or combined with AE on strength parameters and hormones is of high value, since more and recent studies dealing with these types of exercise in PLWH have been published. Methods: Randomized controlled trials evaluating the effects of RT alone, AE alone or the combination of both (AERT) on PLWH was performed through five web-databases up to December 2017. Risk of bias and study quality was attained using the PEDro scale. Weighted mean difference (WMD) from baseline to post-intervention changes was calculated. The I2 statistics for heterogeneity was calculated. Results: Thirteen studies reported strength outcomes. Eight studies presented a low risk of bias. The overall change in upper body strength was 19.3 Kg (95\% CI: 9.8±28.8, p< 0.001) after AERT and 17.5 Kg (95\% CI: 16±19.1, p< 0.001) for RT. Lower body change was 29.4 Kg (95\% CI: 18.1±40.8, p< 0.001) after RT and 10.2 Kg (95\% CI: 6.7±13.8, p< 0.001) for AERT. Changes were higher after controlling for the risk of bias in upper and lower body strength and for supervised exercise in lower body strength. A significant change towards lower levels of IL-6 was found (-2.4 ng/dl (95\% CI: -2.6, -2.1, p< 0.001). Conclusion: Both resistance training alone and combined with aerobic exercise showed a positive change when studies with low risk of bias and professional supervision were analyzed, improving upper and, more critically, lower body muscle strength. Also, this study found that exercise had a lowering effect on IL-6 levels in PLWH.}, language = {en} } @misc{HortobagyiLesinskiFernandez‐del‐Olmoetal.2015, author = {Hortob{\´a}gyi, Tibor and Lesinski, Melanie and Fernandez-del-Olmo, Miguel and Granacher, Urs}, title = {Small and inconsistent effects of whole body vibration on athletic performance}, series = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, number = {627}, issn = {1866-8364}, doi = {10.25932/publishup-43199}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-431993}, pages = {23}, year = {2015}, abstract = {Purpose We quantified the acute and chronic effects of whole body vibration on athletic performance or its proxy measures in competitive and/or elite athletes. Methods Systematic literature review and meta-analysis. Results Whole body vibration combined with exercise had an overall 0.3 \% acute effect on maximal voluntary leg force (-6.4 \%, effect size = -0.43, 1 study), leg power (4.7 \%, weighted mean effect size = 0.30, 6 studies), flexibility (4.6 \%, effect size = -0.12 to 0.22, 2 studies), and athletic performance (-1.9 \%, weighted mean effect size = 0.26, 6 studies) in 191 (103 male, 88 female) athletes representing eight sports (overall effect size = 0.28). Whole body vibration combined with exercise had an overall 10.2 \% chronic effect on maximal voluntary leg force (14.6 \%, weighted mean effect size = 0.44, 5 studies), leg power (10.7 \%, weighted mean effect size = 0.42, 9 studies), flexibility (16.5 \%, effect size = 0.57 to 0.61, 2 studies), and athletic performance (-1.2 \%, weighted mean effect size = 0.45, 5 studies) in 437 (169 male, 268 female) athletes (overall effect size = 0.44). Conclusions Whole body vibration has small and inconsistent acute and chronic effects on athletic performance in competitive and/or elite athletes. These findings lead to the hypothesis that neuromuscular adaptive processes following whole body vibration are not specific enough to enhance athletic performance. Thus, other types of exercise programs (e.g., resistance training) are recommended if the goal is to improve athletic performance.}, language = {en} } @phdthesis{Molinengo2022, author = {Molinengo, Giulia}, title = {The micropolitics of collaborative governance}, doi = {10.25932/publishup-57712}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-577123}, school = {Universit{\"a}t Potsdam}, pages = {x, 128}, year = {2022}, abstract = {Why do exercises in collaborative governance often witness more impasse than advantage? This cumulative dissertation undertakes a micro-level analysis of collaborative governance to tackle this research puzzle. It situates micropolitics at the very center of analysis: a wide range of activities, interventions, and tactics used by actors - be they conveners, facilitators, or participants - to shape the collaborative exercise. It is by focusing on these daily minutiae, and on the consequences that they bring along, the study argues, that we can better understand why and how collaboration can become stuck or unproductive. To do so, the foundational part of this dissertation (Article 1) uses power as a sensitizing concept to investigate the micro-dynamics that shape collaboration. It develops an analytical approach to advance the study of collaborative governance at the empirical level under a power-sensitive and process-oriented perspective. The subsequent articles follow the dissertation's red thread of investigating the micropolitics of collaborative governance by showing facilitation artefacts' interrelatedness and contribution to the potential success or failure of collaborative arrangements (Article 2); and by examining the specialized knowledge, skills and practices mobilized when designing a collaborative process (Article 3). The work is based on an abductive research approach, tacking back and forth between empirical data and theory, and offers a repertoire of concepts - from analytical terms (designed and emerging interaction orders, flows of power, arenas for power), to facilitation practices (scripting, situating, and supervising) and types of knowledge (process expertise) - to illustrate and study the detailed and constant work (and rework) that surrounds collaborative arrangements. These concepts sharpen the way researchers can look at, observe, and understand collaborative processes at a micro level. The thesis thereby elucidates the subtleties of power, which may be overlooked if we focus only on outcomes rather than the processes that engender them, and supports efforts to identify potential sources of impasse.}, language = {en} } @masterthesis{Klaehr2008, type = {Bachelor Thesis}, author = {Klaehr, Alexander}, title = {{\"U}ber die Zusammenh{\"a}nge von Herrschaft und Bildung}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-24456}, school = {Universit{\"a}t Potsdam}, year = {2008}, abstract = {Kann die Schule demokratisch sein?
