Life is Getting Better: Societal Evolution and Fit with Human Nature

Human society has changed much over the last centuries and this process of ‘modernization’ has profoundly affected the lives of individuals; currently we live quite different lives from those forefathers lived only five generations ago. There is difference of opinion as to whether we live better now than before and consequently there is also disagreement as to whether we should continue modernizing or rather try to slow the process down. Quality-of-life in a society can be measured by how long and happy its inhabitants live. Using these indicators I assess whether societal modernization has made life better or worse. Firstly I examine findings of present day survey research. I start with a cross-sectional analysis of 143 nations in the years 2000–2008 and find that people live longer and happier in today’s most modern societies. Secondly I examine trends in modern nations over the last decade and find that happiness and longevity have increased in most cases. Thirdly I consider the long-term and review findings from historical anthropology, which show that we lived better in the early hunter-gatherer society than in the later agrarian society. Together these data suggest that societal evolution has worked out differently for the quality of human life, first negatively, in the change from a hunter-gatherer existence to agriculture, and next positively, in the more recent transformation from an agrarian to an industrial society. We live now longer and happier than ever before

Organisationskultur. Eine Konkretisierung aus systemtheoretischer Perspektive

Kühl S. Organisationskultur. Eine Konkretisierung aus systemtheoretischer Perspektive. Managementforschung. 2018;28(1):7-35.Die Bestimmung des Verhältnisses von Informalität und Organisationskultur bereitet in der Organisationstheorie Schwierigkeiten. Das liegt daran, dass der Begriff Informalität häufig stillschweigend durch den Begriff der Organisationskultur ersetzt wurde, ohne dass dafür eine präzise, abgrenzungsscharfe Definition vorgenommen worden wäre. Unter Rückgriff auf Überlegungen von Dario Rodríguez argumentiert dieser Artikel, dass die beiden Begriffe Organisationskultur und Informalität das gleiche Phänomen bezeichnen: die nichtentschiedenen Entscheidungsprämissen einer Organisation. Dabei wird systematisch zwischen „unentscheidbaren Entscheidungsprämissen“ und „prinzipiell entscheidbaren, aber nicht entschiedenen Entscheidungsprämissen“ unterschieden. Es wird gezeigt, wie sich mit einer präzisen Bestimmung über das Konzept der Entscheidungsprämissen Ordnung in die „wilden Merkmallisten“ der Literatur sowohl über Informalität als auch Organisationskultur bringen lässt und empirische Phänomene genauer erfasst werden können

Emergency coronary artery bypass grafting using minimized versus standard extracorporeal circulation--a propensity score analysis

BACKGROUND: The impact of minimized extracorporeal circulation (MECC) for emergency revascularization remains controversial. METHODS: A total of 348 patients underwent emergency CABG with MECC (n=146) or conventional extracorporeal circulation (CECC; n=175) between January 2005 and December 2010. Using propensity score matching after binary logistic regression, 100 patients, who underwent CABG with MECC could be matched with 100 patients, who underwent CABG with CECC. Primary outcome was 30-day mortality. RESULTS: Unadjusted 30-day mortality was 14.8% in patients with CECC and 6.9% in those with MECC (mean difference -7.9%; p=0.03). The adjusted mean difference (average treatment effect of the treated, ATT) after matching was -1.0% (95% CI -8.6 to 7.6; p=1.0). Intensive care unit stay (adjusted mean difference 1.0; 95% CI -0.2 to 3.2; p=0.70) and hospital stay (adjusted mean difference 1.0; 95% CI -2.0 to 3.6; p=0.40) did not show significant differences between both groups. The adjusted mean difference for postoperative low cardiac output syndrome was -1.1% (95% CI -7.3 to 7.1; p=0.83) without significant differences between CECC and MECC. Postoperative mechanical ventilation time, drain loss, postoperative rethoracotomy, postoperative neurological events, new onset renal replacement therapy and respiratory failure also had insignificant average treatment effects of the treated. In addition, all average treatment effects (ATEs) did not significantly differ between both groups. CONCLUSION: Using propensity score estimation and matching, we did not observe significant differences in terms of survival and further outcomes in patients who undergo emergency CABG with CECC or MECC, but our results call for further analysis

Combined cycle and run performance is maximised when the cycle is completed at the highest sustainable intensity

The aim of this study was to determine the effect of cycle intensity on subsequent running performance and combined cycle–run (CR) performance. Seven triathletes undertook a cycling graded exercise test to exhaustion, an isolated 500-kJ cycle time trial (CTT) and an isolated 5-km running time trial. Then they performed a series of CR tests, at various cycle intensities, followed by an all-out, 5-km run. The CR tests were separated into four categories based on the percentage of the CTT at which the cycle was performed (CR 81–85%, CR 86–90%, CR 91–95%, and CR 96–100%). Running performance was slower during CR 96–100% compared to CR 81–85% and CR 86–90% (20:45 ± 1:19 vs. 19:56 ± 0:40 and 19:46 ± 0:49 min; P 0.05). CR performance was maximised during CR 96–100% when compared to CR 81–85, CR 86–90 and CR 91–95% (56:37 ± 4:04 vs. 62:40 ± 5:30, 59:53 ± 4:41 and 58:29 ± 4:40 min; P < 0.05). The results suggest that combined cycle and run performance is maximised when the cycle is completed at the highest sustainable intensity

Planimetry and Altimetry Thematic Mapping in Part of Perimeter of Project of Land Consolidation in Cadastre Unit Bukovina

Import 26/06/2013Tématem diplomové práce je „Účelové mapování polohopisu a výškopisu v části obvodu projektu pozemkových úprav v katastrálním území Bukovina.“ V první části je poukázáno na důležitost odstranění roztříštěnosti pozemkového vlastnictví na Slovensku a následní obnovu zanedbané a zničené krajiny. Druhá a pátá část se teoreticky a prakticky zabývá geodetickou činností v projektu pozemkových úprav, s využitím poznatků a zkušeností získaných v průběhu studia. Výsledkem práce je vytvořena účelová mapa polohopisu a výškopisu pro projekt pozemkových úprav v katastrálním území Bukovina.The topic of the thesis is quot;assigned mapping topography and elevation in the district land consolidation project in the cadastral Bukovina.quot;. The first part is a reference to the importance of eliminating fragmentation of land ownership to the Slovak and subsequent restoration of derelict and ruined landscape. The second and the fifth part of the theory and practice on the geodetic activities in the project of land consolidation, using the knowledge and experience gained during the study. The result is creation of a dedicated map planimetric and elevation for land consolidation project in the cadastral territory of BukovinaPrezenční544 - Institut geodézie a důlního měřictvívelmi dobř
