Quality management framework for housing construction in a design-build project delivery system : a BIM-UAV approach
Quality management in project administration can affect the costs and schedule of a project considerably. The immediate notable result of unacceptable quality in a construction project is the âdissatisfied client.â which can be interpreted as âcustomer lossâ. Additionally, defective work is a synonym for problems such as dispute, because items of non-compliance with early agreements can be considered the main factor in triggering claims by the client. The integrated use of two modern technologies, namely Building Information Modeling (BIM) and Unmanned Aerial Vehicles (UAV) is proposed in this study to support project quality management (PQM). This study aims to develop the theoretical underpinnings to provide a quality management framework, formed by BIM-UAV, for housing projects in design-build (D&B) contracts. For this purpose, in the first step the causes of client dissatisfaction rooted in quality concerns were identified in two phases of design and construction. The next step was dedicated to the mapping of BIM-UAV capacities to address the identified causes of dissatisfaction of the client. In the final step, expert opinion was obtained to integrate the BIM-UAV capacities to the quality management framework. The findings and main contribution of this study to the body of knowledge is a guide for design-builders to implement BIM-UAV as an innovative quality management solution to improve their services and to gain the maximum level of client satisfaction, focusing on house building
Biografieforschung: theoretische Perspektiven und methodologische Konzepte fĂŒr eine re-konstruktive Geschlechterforschung
Die Biografieforschung bezeichnet einen komplexen Forschungsansatz, der auf eine lange Geschichte des wissenschaftlichen Interesses an "persönlichen Dokumenten" verweisen kann. Sie ist eine voraussetzungsvolle Forschungsperspektive, die sich in zentralen Aspekten ihres Vorgehens auf Biografien als theoretisches Konzept, als historisch-empirischen Gegenstand und als komplexe methodologische Strategie bezieht. Andere Begriffe, welche oftmals synonym gebraucht, in der Biografieforschung aber systematisch unterschieden werden, sind "Lebensgeschichte" und "Lebenslauf". Die Autorin skizziert die Perspektiven einer rekonstruktiven Geschlechterforschung innerhalb der Biografieforschung, wozu sie auf die Differenzierungen empirischer Forschung, die methodologischen Prinzipien sowie auf Datenerhebung und Datenanalyse eingeht. Sie hebt insbesondere drei Kontextrelationen bei der Interpretation eines biografischen Textes hervor: Biografie, Interaktion, kulturelle Muster und soziale Regeln. Das skizzierte Konzept von Biografieforschung begreift sie als ein offenes Programm, das vielfĂ€ltige AnknĂŒpfungspunkte zu aktuellen theoretischen Diskussionen in der Geschlechterforschung aufweist.

Ageâsex differences in the global burden of lower respiratory infections and risk factors, 1990â2019: results from the Global Burden of Disease Study 2019
Summary
Background
The global burden of lower respiratory infections (LRIs) and corresponding risk factors in children older than 5 years and adults has not been studied as comprehensively as it has been in children younger than 5 years. We assessed the burden and trends of LRIs and risk factors across all age groups by sex, for 204 countries and territories.
Methods
In this analysis of data for the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we used clinician-diagnosed pneumonia or bronchiolitis as our case definition for LRIs. We included International Classification of Diseases 9th edition codes 079.6, 466â469, 470.0, 480â482.8, 483.0â483.9, 484.1â484.2, 484.6â484.7, and 487â489 and International Classification of Diseases 10th edition codes A48.1, A70, B97.4âB97.6, J09âJ15.8, J16âJ16.9, J20âJ21.9, J91.0, P23.0âP23.4, and U04âU04.9. We used the Cause of Death Ensemble modelling strategy to analyse 23â109 site-years of vital registration data, 825 site-years of sample vital registration data, 1766 site-years of verbal autopsy data, and 681 site-years of mortality surveillance data. We used DisMod-MR 2.1, a Bayesian meta-regression tool, to analyse ageâsex-specific incidence and prevalence data identified via systematic reviews of the literature, population-based survey data, and claims and inpatient data. Additionally, we estimated ageâsex-specific LRI mortality that is attributable to the independent effects of 14 risk factors.
Findings
Globally, in 2019, we estimated that there were 257 million (95% uncertainty interval [UI] 240â275) LRI incident episodes in males and 232 million (217â248) in females. In the same year, LRIs accounted for 1·30 million (95% UI 1·18â1·42) male deaths and 1·20 million (1·07â1·33) female deaths. Age-standardised incidence and mortality rates were 1·17 times (95% UI 1·16â1·18) and 1·31 times (95% UI 1·23â1·41) greater in males than in females in 2019. Between 1990 and 2019, LRI incidence and mortality rates declined at different rates across age groups and an increase in LRI episodes and deaths was estimated among all adult age groups, with males aged 70 years and older having the highest increase in LRI episodes (126·0% [95% UI 121·4â131·1]) and deaths (100·0% [83·4â115·9]). During the same period, LRI episodes and deaths in children younger than 15 years were estimated to have decreased, and the greatest decline was observed for LRI deaths in males younger than 5 years (â70·7% [â77·2 to â61·8]). The leading risk factors for LRI mortality varied across age groups and sex. More than half of global LRI deaths in children younger than 5 years were attributable to child wasting (population attributable fraction [PAF] 53·0% [95% UI 37·7â61·8] in males and 56·4% [40·7â65·1] in females), and more than a quarter of LRI deaths among those aged 5â14 years were attributable to household air pollution (PAF 26·0% [95% UI 16·6â35·5] for males and PAF 25·8% [16·3â35·4] for females). PAFs of male LRI deaths attributed to smoking were 20·4% (95% UI 15·4â25·2) in those aged 15â49 years, 30·5% (24·1â36·9) in those aged 50â69 years, and 21·9% (16·8â27·3) in those aged 70 years and older. PAFs of female LRI deaths attributed to household air pollution were 21·1% (95% UI 14·5â27·9) in those aged 15â49 years and 18·2% (12·5â24·5) in those aged 50â69 years. For females aged 70 years and older, the leading risk factor, ambient particulate matter, was responsible for 11·7% (95% UI 8·2â15·8) of LRI deaths.
Interpretation
The patterns and progress in reducing the burden of LRIs and key risk factors for mortality varied across age groups and sexes. The progress seen in children younger than 5 years was clearly a result of targeted interventions, such as vaccination and reduction of exposure to risk factors. Similar interventions for other age groups could contribute to the achievement of multiple Sustainable Development Goals targets, including promoting wellbeing at all ages and reducing health inequalities. Interventions, including addressing risk factors such as child wasting, smoking, ambient particulate matter pollution, and household air pollution, would prevent deaths and reduce health disparities
