Haltung der katholischen Kirche in Westfalen zum und während des Ersten Weltkrieg
Die Arbeit fragt nach der Haltung und dem Verhalten der katholischen Kirche, genauer gesagt, des Bistums Münster, im Ersten Weltkrieg. Einerseits bot die Kirche vielen Westfalen in ihren seelsorgerischen Aktivitäten Trost und Unterstützung angesichts von Schwierigkeiten und Leid im Krieg. Andererseits leistete sie einen wesentlichen Beitrag dazu, bis zuletzt den Krieg zu legitimieren und ihre Gläubigen auf die Kriegsziele einzuschwören. Nicht zuletzt versuchte sie so, die Gläubigen enger an die Kirche zu binden
Workplace learning and organisational performance in the hospitality industry.
Purpose The hospitality industry creates a distinctive context in which learning takes place. The industry's international perspective and large globalisation play an important role in learning, as well as the operational and structural features that give meaning to learning and development in the hospitality industry. This explorative research therefore studies the relation between workplace learning and organisational performance in the Dutch hospitality industry. Design/methodology/approach The qualitative research is done through 15 in-depth interviews with general managers and HR managers of Dutch hotels with three or more stars and at least ten employees. Findings It can be concluded that there is a relation between workplace learning and organisational performance in the hospitality industry, as the participants in this research and the literature both mention workplace learning enhances organisational performance. Originality/value Little research has been done on learning and organisational performance specifically, in the (Western) hospitality industry. This research therefore focusses on HRD and studies the influence of workplace learning on organisational performance in the Dutch hospitality industry
Is Our Model for Contention Resolution Wrong?
Randomized binary exponential backoff (BEB) is a popular algorithm for
coordinating access to a shared channel. With an operational history exceeding
four decades, BEB is currently an important component of several wireless
standards. Despite this track record, prior theoretical results indicate that
under bursty traffic (1) BEB yields poor makespan and (2) superior algorithms
are possible. To date, the degree to which these findings manifest in practice
has not been resolved.
To address this issue, we examine one of the strongest cases against BEB:
packets that simultaneously begin contending for the wireless channel. Using
Network Simulator 3, we compare against more recent algorithms that are
inspired by BEB, but whose makespan guarantees are superior. Surprisingly, we
discover that these newer algorithms significantly underperform. Through
further investigation, we identify as the culprit a flawed but common
abstraction regarding the cost of collisions. Our experimental results are
complemented by analytical arguments that the number of collisions -- and not
solely makespan -- is an important metric to optimize. We believe that these
findings have implications for the design of contention-resolution algorithms.Comment: Accepted to the 29th ACM Symposium on Parallelism in Algorithms and

Analysis of civic initiatives: Multiparameter classification of social innovations
This paper focuses on the topical and problematic area of social innovations. The aim of this paper is to develop an original approach to the allocation of social innovations, taking into account characteristics such as the degree of state participation, the scope of application, the type of initiations as well as the degree of novelty, which will be elaborated on further in this article. In order to achieve this goal, the forty-two most successful social innovations were identified and systematized. The results of this study demonstrated that 73.5% of social innovations are privately funded, most of them operating on an international level with a high degree of novelty. Moreover, 81% of all social innovations are civic initiatives. Social innovations play an important role in the growth of both developed and less developed countries alike as highlighted in our extensive analysis. © 2016 Evgeny Popov, Jol Stoffers, Zhoomart Omonov and Anna Veretennikova
Olfactory testing combined with dopamine transporter imaging as a method to detect prodromal Parkinson's disease
Assessment of myocardial injury after reperfused infarction by T1ρ cardiovascular magnetic resonance.
BackgroundThe evolution of T1ρ and of other endogenous contrast methods (T2, T1) in the first month after reperfused myocardial infarction (MI) is uncertain. We conducted a study of reperfused MI in pigs to serially monitor T1ρ, T2 and T1 relaxation, scar size and transmurality at 1 and 4 weeks post-MI.MethodsTen Yorkshire swine underwent 90 min of occlusion of the circumflex artery and reperfusion. T1ρ, T2 and native T1 maps and late gadolinium enhanced (LGE) cardiovascular magnetic resonance (CMR) data were collected at 1 week (n = 10) and 4 weeks (n = 5). Semi-automatic FWHM (full width half maximum) thresholding was used to assess scar size and transmurality and compared to histology. Relaxation times and contrast-to-noise ratio were compared in healthy and remote myocardium at 1 and 4 weeks. Linear regression and Bland-Altman was performed to compare infarct size and transmurality.ResultsRelaxation time differences between infarcted and remote myocardial tissue were ∆T1 (infarct-remote) = 421.3 ± 108.8 (1 week) and 480.0 ± 33.2 ms (4 week), ∆T1ρ = 68.1 ± 11.6 and 74.3 ± 14.2, and ∆T2 = 51.0 ± 10.1 and 59.2 ± 11.4 ms. Contrast-to-noise ratio was CNRT1 = 7.0 ± 3.5 (1 week) and 6.9 ± 2.4 (4 week), CNRT1ρ = 12.0 ± 6.2 and 12.3 ± 3.2, and CNRT2 = 8.0 ± 3.6 and 10.3 ± 5.8. Infarct size was not significantly different for T1ρ, T1 and T2 compared to LGE (p = 0.14) and significantly decreased from 1 to 4 weeks (p < 0.01). Individual infarct size changes were ∆T1ρ = -3.8%, ∆T1 = -3.5% and ∆LGE = -2.8% from 1 - 4 weeks, but there was no observed change in infarct size for T2 or histologically.ConclusionsT1ρ was highly correlated with alterations left ventricle (LV) pathology at 1 and 4 weeks post-MI and therefore it may be a useful method endogenous contrast imaging of infarction
New system for drying poultry manure in belt batteries
Voor het drogen van mest op legbatterijen met mestbanden is een systeem ontwikkeld. Hierbij wordt lucht door polyethyleen buizen in de nok van de stal geblazen die aldus opgewarmd door geperforeerde buizen over de mest op de mestbanden geblazen wordt. De voorgedroogde mest wordt daarna buiten op een overdekte mesthoop opgeslagen waar het door spontane compostering verder opdroogt. Dit systeem biedt economisch gezien meer voordelen dan de dieppit- of de kanalensta
