That we live in a time of unprecedented and ever-increasing change is both a shibboleth of our age and the more-or-less explicit justification for all manner of “strategic” actions. The seldom, if ever, questioned assumption is that our now is more ephemeral, more evanescent, than any that preceded it. In this essay, we subject this assumption to some critical scrutiny, utilizing a range of empirical detail. In the face of this assay we find the assumption to be considerably wanting. We suggest that what we are actually witnessing is mere acceleration, which we distinguish as intensification along a preexisting trajectory, parading as more substantive and radical movement away from a preexisting trajectory. Deploying Deleuze's (2004) terms we are, we suggest, in thrall to representation of the same at the expense of repetition of difference. Our consumption by acceleration, we argue, both occludes the lack of substantive change actually occurring while simultaneously delimiting possibilities of thinking of and enacting the truly radical. We also consider how this setup is maintained, thus attempting to shed some light on why we are seemingly running to stand still. As the Red Queen said, “it's necessary to run faster even to stay in the one place.”

Purpose of review: Postnatal pelvic floor muscle training aims to rehabilitate the pelvic floor muscles. To be effective, a certain exercise dosage must be respected. Recent trials evaluated the effect of different programs on prevention/treatment of urinary incontinence immediately after delivery and in treatment of persistent incontinence. Recent findings: Only three systematic reviews, six trials, and four follow-up studies have been published in the past two decades. High heterogeneity in postnatal pelvic floor muscle training programs is observed throughout the literature, making comparisons difficult. In the prevention/treatment of postnatal urinary incontinence immediately after delivery and in persistent incontinence, supervised intensive programs prove more effective than standard postnatal care. Longer-term results have yet to show advantages for postnatal training programs. Summary: Although a certain exercise dosage must be respected for a postnatal pelvic floor muscle training program to be effective, a few randomized controlled trials present such dosage. Randomized controlled trials should study the effect of supervised, intensive training protocols with adherence aids. As standard care does not seem to reduce the prevalence of postnatal urinary incontinence, obstetrics services must address delivery of postnatal pelvic floor muscle training.

A comprehensive approach to sport expertise should consider the entire situation that is comprised of the person, the task, the environment, and the complex interplay of these components (Hackfort, 1986). Accordingly, the Developmental Model of Sport Participation (Côté, Baker, & Abernethy, 2007; Côté & Fraser-Thomas, 2007) provides a comprehensive framework for sport expertise that outlines different pathways of involvement in sport. In pathways one and two, early sampling serves as the foundation for both elite and recreational sport participation. Early sampling is based on two main elements of childhood sport participation: 1) involvement in various sports and 2) participation in deliberate play. In contrast, pathway three shows the course to elite performance through early specialization in one sport. Early specialization implies a focused involvement on one sport and a large number of deliberate practice activities with the goal of improving sport skills and performance during childhood. This paper proposes seven postulates regarding the role that sampling and deliberate play, as opposed to specialization and deliberate practice, can have during childhood in promoting continued participation and elite performance in sport.

Background: It is well known that sprint interval training (SIT), induces significant increases in peak oxygen uptake (VO2peak) at the group level. However, there have been only a few studies that have addressed the variability of VO2peak response following SIT, and precise mechanism(s) that may explain individual magnitude of response are unknown. Purpose: Therefore, the purpose of this thesis was to: 1) examine the inter-individual variability of the VO2peak response following SIT, 2) to inspect the relationship between changes in both central and peripheral measures and changes in VO2peak, and 3) to assess if peripheral or central adaptations play a role in whether an individual is a high or low responder with respect to VO2peak. Subjects: Twenty-two young, recreationally active males (age: 20.4 1.7 years; weight: 78.4 10.2 kg; VO2peak: 3.7 0.62 L/min) Methods: VO2peak (L/min), peak cardiac output (Qpeak [L/min]), and peak deoxygenated hemoglobin (HHbpeak [mM]) were measured before and after 16 sessions of SIT (Tabata Protocol) over four weeks. Peak a-vO2diff was calculated using a derivation of the Fick equation. Results: Due to a systematic error, HHbpeak could not be used to differentiate between individual responses. There was a large range of VO2peak response from pre to post testing (-4.75 to 32.18% change) and there was a significant difference between the Low Response Group (LRG) (n=8) and the High Response Group (HRG) (n=8) [f(1, 14)= 64.27, p<0.001]. Furthermore, there was no correlation between delta () VO2peak and Qpeak (r=-0.18, p=0.46) for all participants, nor was there an interaction effect between the Low and High Response Groups [f(1,11)=0.572, p=0.47]. Lastly, there was a significant correlation between VO2peak and peak a-vO2diff [r=0.692, p<0.001], and a significant interaction effect with peak a-vO2diff [f(1, 14)= 13.27, p<0.004] when comparing the HRG to the LRG. Conclusions: There was inter-individual variability of VO2peak response following 4 weeks of SIT, but central adaptations did not influence this variation. This suggests that peripheral adaptations may be responsible for VO2peak adaptation.

Our case study of charismatic celebrity comedian Russell Brand’s turn to political activism uses Bourdieu’s field theory to understand the process of celebrity migration across social fields. We investigate how Brand’s capital as a celebrity performer, storyteller and self-publicist translated from comedy to politics. To judge how this worked in practice, we analysed the comedic strategies used in his stand-up show Messiah Complex and undertook a conversational analysis of his notorious interview with Jeremy Paxman on the British Broadcasting Corporation (BBC)’s flagship current affairs programme Newsnight. We argue that Brand was able to secure political legitimacy by creatively constituting himself as an authentic anti-austerity spokesperson for the disenfranchised left in United Kingdom. In order to do so, he repurposed his celebrity capital to political ends and successfully deployed the cultural and social capitals he had developed as a celebrity comedian to secure widespread engagement with his media performances.

[EN] The emergent marine deposits of the Mediterranean basin have been recognized as an important record of Quaternary sea level history for more than a century. Previous workers identified what have been interpreted to be two separate high stands of sea in the late Quaternary, namely the "Eutyrrhenian" (thought to be ~ 120 ka) and the "Neotyrrhenian" (thought to be either ~ 100 ka or ~ 80 ka). On Mallorca, Spain, both of these named deposits lie close to present sea level, implying paleo-sea levels slightly above present during both marine isotope stages (MIS) 5.5/5e and either 5.3/5c or 5.1/5a. If these interpretations are correct, they conflict, at least in part, with sea level records from far-field localities.

Due to the overwhelming burden of colorectal cancer (CRC), great effort has been placed on identifying genetic mutations that contribute to disease development and progression. One of the most studied polymorphisms that could potentially increase susceptibility to CRC involves the nucleotide-binding and oligomerization-domain containing 2 (NOD2) gene. There is growing evidence that the biological activity of NOD2 is far greater than previously thought and a link with intestinal microbiota and mucosal immunity is increasingly sought after. In fact, microbial composition may be an important contributor not only to inflammatory bowel diseases (IBD) but also to CRC. Recent studies have showed that deficient NOD2 function confers a communicable risk of colitis and CRC. Despite the evidence from experimental models, population-based studies that tried to link certain NOD2 polymorphisms and an increase in CRC risk have been described as conflicting. Significant geographic discrepancies in the frequency of such polymorphisms and different interpretations of the results may have limited the conclusions of those studies. Since being first associated to IBD and CRC, our understanding of the role of this gene has come a long way, and it is tempting to postulate that it may contribute to identify individuals with susceptible genetic background that may benefit from early CRC screening programs or in predicting response to current therapeutic tools. The aim of this review is to clarify the status quo of NOD2 mutations as genetic risk factors to chronic inflammation and ultimately to CRC. The use of NOD2 as a predictor of certain phenotypic characteristics of the disease will be analyzed as well.

Das vorliegende Papier soll zur Unterstützung der Diskussion um Personalmindeststandards im Pflegebereich dienen. Dazu wird zunächst ein Rückblick auf die Vorgeschichte und Hintergründe des Stellenabbaus sowie die Auswirkungen des Pflege-Förderprogramms und dessen Überführung in das DRG-System gegeben. Da die Frage einer staatlichen Regulierung der Personalbesetzung im Pflegedienst der Krankenhäuser sehr eng mit der Verteilung der Gesetzgebungskompetenzen zwischen Bund und Ländern verbunden ist, werden im darauf folgenden Kapitel Möglichkeiten und Grenzen einer Regulierung durch Landesrecht oder Bundesrecht vorgestellt und diskutiert. Daran schließt sich ein Überblick über die wichtigsten bisher vorgelegten Überlegungen und Vorschläge für eine staatliche Regulierung der Personalbesetzung an. Im darauf folgenden Kapitel werden die bisherigen Vorschläge einer kritischen Analyse unterzogen, dabei wird insbesondere auf die Frage der Eignung des DRG-Systems als Ansatzpunkt für eine Regulierung der Personalbesetzung eingegangen. Daran anschließend werden zwei Regulierungsansätze, die möglicherweise besser geeignet wären, um verbindlich einzuhaltende Personalbesetzungsstandards nicht nur vorzugeben, sondern auch durchzusetzen: Eine Regulierung auf Landesebene im Rahmen der Krankenhausplanung und eine Regulierung auf Bundesebene, die den OPS nutzt, um die Einhaltung vorgegebener Personalbesetzungsstandards zur Bedingung für die Kodierung und somit auch Abrechnung von Leistungen macht. Das letzte Kapitel ist der Frage der Finanzierung verbindlich eizuhaltender Personalbesetzungsstandards gewidmet.

Im Forschungsprojekt "Prozesse der Sprachförderung im Kindergarten – ProSpiK" werden Gespräche zwischen Lehrpersonen und Kindern gefilmt und sequenzanalytisch ausgewertet, um ihre Potenziale für den Erwerb und die Förderung bildungssprachlicher Fähigkeiten zu untersuchen. Ziel ist es, Grundlagen für eine stufengerechte (integrierte, situations- und themenorientierte) Sprachdidaktik zu erarbeiten, die Bildungsungleichheit abbauen hilft, anstatt sie zu reproduzieren. In der Nummer 3/2014 der Schweizerischen Zeitschrift für Bildungswissenschaften wurden die Anlage des Projekts und erste Auswertungsergebnisse (zum Phänomen «Wechsel von Referenzräumen») vorgestellt (Isler, Künzli, & Wiesner, 2014). Der vorliegende Beitrag befasst sich weiter vertiefend mit der Ausgestaltung von pädagogischen Gesprächen: Es wird untersucht, mit welchen kommunikativen Mitteln die Kinder beim Erwerb von Fähigkeiten des Argumentierens (Beziehen und Begründen eigener Positionen) unterstützt werden können.2 Im ersten Abschnitt geht es um die Bedeutung der Prozessqualität in der frühen Bildung und um Gespräche als Erwerbskontexte sprachlicher Fähigkeiten. Im zweiten Abschnitt werden zentrale theoretische Konzepte dargestellt, die unseren Analysen zugrunde liegen. Der dritte Abschnitt gibt einen exemplarischen Einblick in das Datenmaterial und die Auswertungsarbeiten. Im vierten Abschnitt wird anhand einer exemplarischen Analyse gezeigt, wie im Kindergarten multimodal gelernt werden kann. Abschliessend werden die Ergebnisse mit Bezug auf die Forschungsfragen des Projekts diskutiert. (DIPF/Orig.)

Koulunkäynninohjaajien ammattikunta on vakiintunut osaksi peruskoulujen henkilökuntaa jo 1990- luvulla. Heitä työskentelee Suomen kouluissa noin 9000. Taustalla on peruskoulun voimakas muuttuminen viime vuosina. Oppilaan tuen painopiste on siirtynyt enemmän lähikouluihin ja tavallisiin luokkiin. Opiskeluhuoltolaki on muuttunut ja uusi opetussuunnitelma otetaan käyttöön syksyllä. Muutosten seurauksena koulun aikuisten yhteistyöhön on välttämätöntä kiinnittää aiempaa enemmän huomiota. Vaikka koulunkäynninohjaajien tehtäväkuva on laajentunut ja monipuolistunut vuosien kuluessa, heidän ammatillinen statuksensa on paikoin epäselvä. Suomessa ei ole tehty paljonkaan tutkimusta koulunkäynninohjaajiin liittyen. Tässä tutkimuksessa kysytään, minkälaista yhteistyötä opettajat ja koulunkäynninohjaajat tekevät, millaista vuorovaikutusta heidän välillään on ja mitä ovat ne tekijät, mitkä yhteistyön onnistumiseen tai epäonnistumiseen vaikuttavat. Lopuksi esitän joitakin ehdotuksia yhteistyön ja vuorovaikutuksen helpottamiseksi. Tutkimus toteutettiin teemahaastatteluna kuudessa eri koulussa. Haastateltavina oli neljä opettajaa ja neljä koulunkäynninohjaajaa. Kaikilla tutkimukseen osallistuneilla on pitkä kokemus opettaja-ohjaaja työparityöskentelystä. Tässä tutkimuksessa havaittiin opettajan ja koulunkäynninohjaajan välisen yhteisen suunnittelun olevan keskeistä hyvän yhteistyön toteutumiselle. Luokassa tapahtuvan vuorovaikutuksen laatu ja ilme on pitkälti seurausta yhteisestä suunnittelusta. Yhteistyön ja vuorovaikutuksen taustalla vaikuttavina tekijöinä havaittiin johdon tuki, resurssit, koulutus tai sen vähäisyys, ohjaajien ammatillinen status, erilainen käsitys ohjaamisesta, opettamisesta tai suhtautumisesta lapsiin, ammattien välinen kilpailu, odotukset yhteistyöltä, tiedonkulku tai tiedonkulun ongelmat, joustavuus sekä keskinäinen arvostus tai sen puute. Yksi tärkeimpiä havaintoja oli se, että opettajat eivät saa, mutta tarvitsisivat yliopistossa koulutusta ohjaajien kanssa työskentelyyn. Lisäksi havaittiin, että koulunkäyntiavustajien ammattinimikkeen vaihtuminen koulunkäynninohjaajan ammattinimikkeeksi on herättänyt huolta opettajaprofession puolella. Ammattinimikkeen muutoksen kautta koulunkäynninohjaajat kykenevät kuitenkin vahvistamaan asemaansa koulun ammattilaisina, mikä voi vaikuttaa yhteistyön laatua parantavasti.

In order to grow and survive, a firm must create value with consumers in ways that both fit in with consumer demands and stand out from competitors. Focusing on and understanding consumer and firm assessments of value and creation of value has become a central scope in the contemporary strategic management and marketing literature for understanding and explaining firm survival and success. Consequently, the overall aim of this thesis is to provide a conceptually and empirically grounded understanding of consumers’ and managers’ value assessments and behavior in value creation. This thesis draws on a consumer experience perspective and theories on social construction, organizational identity, self-congruence, and the theory of attractive quality, and combines multiple qualitative and quantitative studies. The findings in this thesis shed light on the interplay between consumers, firms, and contextual structures in value creation. Contextual structural, cultural, and political forces are shown to affect and be affected by the shared and individual cognitions of value creation that firms and consumers use in their assessment and creation value. The results of the study enhance the understanding of how firms can adopt various strategic schemas or organizing logics to optimize different types of use value creation when choosing between opposing and contradictive demands in their value creation. Furthermore, the thesis provides a deeper understanding of the hierarchical nature of consumer judgments of value that can be used to enhance the effectiveness of firm prioritizations and as a foundation for future value-creating strategies.
