Hintergrund Die Osteitis pubis ist eine häufige Ursache chronischer Leistenbeschwerden. Aufgrund hoher klinischer Unsicherheit sowie dem unterschiedlichen Verlauf der Erkrankung wird die Diagnose nicht selten erst spät gestellt. Das Krankheitsbild betrifft insbesondere Sportlerinnen und Sportler, wobei auch Patienten aus den Bereichen Orthopädie, Traumatologie, Neurologie, Urologie, Gynäkologie sowie der Rheumatologie betroffen sein können. Therapeutisch kommen sowohl konservative als auch operative Verfahren zum Einsatz. Material und Methoden Systematische Literaturrecherche, deskriptive Darstellung der Studienlage und Interpretation der Ergebnisse im Sinne der evidenzbasierten Medizin. Ergebnisse Das wissenschaftliche Niveau der Studien über die Osteitis pubis ist, wie die Anzahl der in Studien inkludierten Sporttreibenden, insgesamt niedrig. Aufgrund der Heterogenität der Publikationen ist ihr statistischer Vergleich methodisch schwierig. Klinisch führendes Symptom der Osteitis pubis ist die schmerzhafte Symphysis pubica, wobei ein klassisches pathognomonisches Zeichen fehlt. Die Diagnose basiert nach Ausschluss zahlreicher Differentialdiagnosen (z. B. „Sportlerleiste“, FA-Impingement, Adduktorenläsion) auf der Zusammenschau von Anamnese, klinischer Untersuchung sowie bildgebender Verfahren. Die Osteitis pubis ist eine durch Sportkarenz oftmals selbstlimitierende Erkrankung, die initial konservativ behandelt wird. Bei frustranem Verlauf sind operative Verfahren, in Abhängigkeit der Begleitpathologien, in Betracht zu ziehen. Schlussfolgerung Es existieren bis dato keine Leitlinien hinsichtlich Diagnostik und Therapie der Osteitis pubis, allerdings ein Konsens darüber, dass der operativen Behandlung eine konservative vorangehen muss. Das Evidenzniveau der Studien ist niedrig. Eine metaanalytische Auswertung ist mit den derzeitig vorhandenen Publikationen nicht möglich. Die Anzahl der untersuchten Sporttreibenden ist in Relation zu den sozioökonomischen Folgen der Erkrankung, insbesondere im Profisport, niedrig. [less ▲]

We show that the annual excess return of the S&P 500 is almost 10 percent higher during the last two years of the presidential cycle than during the first two years. This pattern cannot be explained by business-cycle variables capturing timevarying risk premia, differences in risk levels, or by consumer and investor sentiment. We formally test the presidential election cycle (PEC) hypothesis as the alternative explanation found in the literature for explaining the presidential cycle anomaly. The PEC states that incumbent parties and presidents have an incentive to manipulate the economy (via budget expansions and taxes) to remain in power. We formulate eight empirically-testable propositions relating to the fiscal, monetary, tax, unexpected inflation and political implications of the PEC hypothesis. We do not find statistically significant evidence confirming the PEC hypothesis as a plausible explanation for the presidential cycle effect. The presidential cycle effect in U.S. financial markets thus remains a puzzle that cannot be easily explained by politicians employing their economic influence to remain in power, as is often believed.

One single code change can significantly influence a wide range of software systems and their users. For example, 1) adding a new feature can spread defects in several modules, while 2) changing an API method can improve the performance of all client programs. Developers often may not clearly know whether their or others’ changes are influential at commit time. Rather, it turns out to be influential after affecting many aspects of a system later. This paper investigates influential software changes and proposes an approach to identify them early, i.e., immediately when they are applied. We first conduct a post- mortem analysis to discover existing influential changes by using intuitions such as isolated changes and changes referred by other changes in 10 open source projects. Then we re-categorize all identified changes through an open-card sorting process. Subsequently, we conduct a survey with 89 developers to confirm our influential change categories. Finally, from our ground truth we extract features, including metrics such as the complexity of changes, terms in commit logs and file centrality in co-change graphs, to build ma- chine learning classifiers. The experiment results show that our prediction model achieves overall with random samples 86.8% precision, 74% recall and 80.4% F-measure respectively. [less ▲]

This study aims to determine the relationships between local meteorological conditions, proglacial river discharge and biogeochemical processes operating in a periglacial basin located in the Polar Ural mountain range, Russia. Fieldwork was conducted in the catchment of Obruchev Glacier (13 km2) during the summer peak flow period in 2008. River discharge was dominated by snowmelt and changed from 3300 l s-1 to less than 1000 l s-1. The mean daily air temperatures of stations situated in the mountain tundra and near Obruchev Glacier from July 11th to August 1st 2008 were 14.4°C and 10.3°C, respectively. The glacial river had low total dissolved solids varying from 4.5 to 9 mg l-1 and coefficients of correlation between Na+ and Cl-, K+ and Cl-, as well as NH4+ and Cl- were 0.94, 0.90 and 0.84, respectively. Rainfall events affected the snowmelt initiation and provided an essential part of the discharge during the intense snowmelt period, which occurred from July 11th to July 18th 2008. Data showed that Na+ and K+ in the surface water derived from snowmelt rather than chemical weathering of silicates. Also, it was obtained that NO3- derived from the melting snowpack, whereas ammonification occurring under the snowpacks was the primary source for NH4+. [less ▲]

The sensitivity for one’s own internal body signals (i.e., interoception) has been demonstrated to play an important role in the pathogenesis of eating and weight disorders. Most previous measures assessing interoceptive processing have not, or only partly, captured perception of hunger and satiety cues, which is a core aspect of interoceptive deficits in eating disorders. In addition, methods used to measure sensitivity to gastric signals are heterogeneous and findings inconsistent. The primary aim of the present study was to establish a standardised test to measure gastric interoception, and to provide normative data using a non-clinical adult sample. The two-step Water Load Test (WLT-II) involves ingestion of non-caloric water until perceived satiation (step 1) and until maximum fullness (step 2). The WLT-II consists of several variables: Besides volumes of water ingested until satiation and maximum fullness expressed in ml, percentage of satiation to maximum fullness is calculated as an individual index of gastric interoception that is not confounded with stomach capacity. Ninety-nine healthy women participated in the study. Measures included the WLT-II, the heartbeat tracking test, a self-report questionnaire assessing subjective sensations, and the Eating Disorder Inventory-2. Twenty-eight participants underwent test-retest of the WLT-II. Results suggest that the WLT-II is a valid and reliable measure of gastric interoception. Importantly, satiation volume and percentage of satiation to maximum fullness were strongly positively related to self-reported bulimic symptoms, indicating that the WLT-II could emerge as a useful clinical tool to measure interoceptive processing in the field of eating disorders.

Recent experiments on noncovalent interactions at the nanoscale have challenged the basic assumptions of commonly used particle- or fragment-based models for describing van der Waals (vdW) or dispersion forces. We demonstrate that a qualitatively correct description of the vdW interactions between polarizable nanostructures over a wide range of finite distances can only be attained by accounting for the wavelike nature of charge density fluctuations. By considering a diverse set of materials and biological systems with markedly different dimensionalities, topologies, and polarizabilities, we find a visible enhancement in the nonlocality of the charge density response in the range of 10 to 20 nanometers. These collective wavelike fluctuations are responsible for the emergence of nontrivial modifications of the power laws that govern noncovalent interactions at the nanoscale. [less ▲]

The phenomenon of non-mediation is an important factor in virtual experiences. Users seem to ignore their physical surroundings and become present in the virtual environment (VE). Assessing presence in VEs with continuous measures is an ongoing effort both to complement the data provided by self-report measures and to identify specific events during virtual experiences that disrupt presence (“breaks in presence”; BIPs, Slater & Steed, 2002). Early studies employed self-report measures for BIPs, but have also identified specific psychophysiological reactions bearing the potential to develop a continuous measure—the nature of these reactions, however, has been unclear. We argue that BIPs can be considered as orienting responses (ORs; Sokolov, 1963) as users interact with VEs based on dedicated mental models and direct all their attention to virtual stimuli. When a new virtual stimulus is incompatible with these mental models, an OR is triggered, directing user attention at the source of the stimulus to determine its cause. ORs have been linked to psychophysiological reactions (Bradley, 2009) similar to the ones reported for BIPs. We designed a series of three studies to investigate this account to BIPs. Two studies are already complete, while a third study is currently being conducted. In all studies, users played Skyrim (Bethesda, 2011) modified to include stimuli that can be considered as BIPs not belonging to the VE. We measured psychophysiological responses using ECG and GSR. In study 1 (N = 31) participants played for M = 82.08 minutes (SD = 34.23) and encountered ten different types of BIP stimuli (e.g. error message, game crash) determined empirically through a prestudy. In line with previous literature on ORs, we found significant responses in ECG and GSR for all BIPs with a clearly defined stimulus onset. Additionally, we found a habituation effect of repeated exposure to the error message consistent with habituation of orienting. Analysis of blinking activity showed prolonged intervals during BIPs consistent with the information acquisition function of ORs. In study 2 (N = 69) participants played for M = 22.02 minutes (SD = 7.1). We employed a modified secondary-task reaction time (STRT) procedure in addition to psychophysiological measurements to compare ORs towards a game-related stimulus with ORs towards a BIP-stimulus. By pressing a footswitch, participants had to react to a crying baby, embedded into the game’s narrative, or a similarly pitched interference pattern of two sinewaves. Although we expected faster reaction times for game-related stimuli, we found similar reaction times for both types of stimuli. However, we could replicate the psychophysiological patterns from study 1. Both sounds equally elicited ORs with game-related stimuli leading to stronger responses and habituation. The data from the first two studies indicate that BIPs can be considered a type of OR, suggesting a promising avenue towards continuous measurement of presence. Following a similar design, Study 3 employs a STRT task based on more intricate considerations of the processes in human working memory (Oberauer, 2009). Additionally, pupil dilation is being assessed to investigate cognitive load associated with responses to game-related stimuli and BIPs. [less ▲]
