description: Infertility poses multifaceted challenges, encompassing emotional, psychological, and socio-economic dimensions to humans. This study investigated the effect of the co-administration of aqueous extract of Cyperus esculentus (tiger nuts) and vitamins (vitamin C and vitamin E) on male reproductive organ histology and fertility indices in albino rats. The experimental design involved administering an oral median lethal dose (LD50) of tiger nuts to 91 male albino rats. They were divided into thirteen groups, each comprising seven animals. Groups included a Control Group for baseline comparison, Aqueous Extract Groups (2-4) to study dose-dependent effects, Aqueous Extract + Vitamin C Groups (5-7) to explore combined effects, Aqueous Extract + Vitamin E Groups (8-10) to examine antioxidant influence, and Aqueous Extract + Vitamins C and E Groups (11-13) for a comprehensive understanding of potential interactions. The study spanned 21 days, evaluating the impact on testicular conditions. The serial sections were stained using hematoxylin and Eosin staining techniques for the testes tissue. The study found a significant difference in testicular weight among different groups of albino rats. Group 11 had the highest testicular weight, while the control group had the least. Testicular weights in groups fed with Vitamin E and a combination of vitamin C and E were significantly higher than those fed with tiger nut only and Vitamin C. Additionally, testosterone levels varied significantly among groups, with higher levels in groups receiving Vitamin E and a combination of vitamin C and E. Vitamin C levels did not show a significant difference among groups, but vitamin E levels were significantly higher in specific groups (12 and 13) compared to others. Histological examinations revealed enhanced spermatogenic maturation and preserved testicular architecture. Overall, the study observed vacuolations and Leydig cell changes, suggesting physiological effects on testicular weight, hormonal levels, and vitamin concentrations in albino rats. The study finds that tiger nut extract, combined with vitamin E or vitamins C and E, significantly boosts testicular weight and serum testosterone in albino rats, supporting spermatogenesis. Particularly, vitamin E enhances spermatogenic maturation, interstitial cells, and blood vessels. Histological examination shows preserved testicular morphology, indicating a healing effect. In conclusion, administering tiger nut extract with vitamins, notably vitamin E, improves fertility indices in male albino rats.

description: Joint injuries are highly associated with cell death and development of posttraumatic osteoarthritis (PTOA). The present study focused on necroptosis as a possible modality of chondrocyte death after cartilage trauma and its relevance in OA disease in general. For this purpose, apoptosis- and necroptosis-associated markers were determined in highly degenerated (ICRS ≥ 3) as well as macroscopically intact cartilage tissue (ICRS ≤ 1) by means of real-time PCR and immunohistochemistry (IHC). Moreover, influence of blunt trauma and/or stimulation with cycloheximide (CHX), TNF-a, and caspase-inhibitor zVAD were investigated in cartilage explants (ICRS ≤ 1). Further characterization of necroptosis was performed in isolated chondrocytes. We found that gene expression levels of RIPK3 (4.2-fold, P < 0.0001) and MLKL (2.7-fold, P < 0.0001) were elevated in highly degenerated cartilage tissue, which was confirmed by IHC staining. After ex vivo trauma and/or CHX/TNF stimulation, addition of zVAD further enhanced expression of necroptosis-related markers as well as release of PGE2 and nitric oxide, which was in line with increased cell death and subsequent release of intracellular HMGB1 and dsDNA in CHX/TNF stimulated chondrocytes. However, trauma and/or chemically induced cell death and subsequent release of pro-inflammatory mediators could be largely attenuated by RIPK1-inhibitor necrostatin 1 or antioxidant N-acetylcysteine. Overall, the study provided clear evidence of necroptotic cell death in OA disease. Moreover, a possible link between cartilage injury and necroptotic processes was found, depending on oxidative stress and cytokine release. These results contribute to further understanding of cell death in PTOA and development of novel therapeutic approaches.

description: In this part of the report, the results of the qualitative analyses on municipal climate protection measures and fields of action are summarised in the form of profiles. The profiles show which measures are implemented voluntarily or within the framework of existing obligations. Different ambition levels of municipal climate protection action are presented. In this respect, it was made transparent in the 20 profiles that were compiled that municipal climate protection is in no way adequately addressed in sectoral legislation and that almost all options are of a voluntary nature. Possibilities can hardly be exploited due to technical and personnel bottlenecks. If climate protection criteria are added to sectoral laws, the additional personnel costs incurred by municipalities are not remunerated or financially compensated. Quelle: Foschungsbericht

description: Background: Though several epidemiological surveys of psychiatric disorders have been carried out in China, only a few of them are concerned about the prevalence of psychiatric disorders in central Hunan and reveal the distribution of common psychiatric disorders and their comorbidities. Methods: Achenbach’s Child Behavior Checklist (CBCL), the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID), and Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) were administered to a stratified sample of 17,071 participants aged 6 to 16 years old from two cities in the central part of Hunan province. Twelve-month prevalence rates were calculated. Results: Twelve-month prevalence of the population was 9.74%. The most common psychiatric disorders were attention deficit hyperactivity disorder (ADHD) (4.96%), oppositional defiant disorder (ODD) (2.98%) and generalized anxiety disorder (GAD) (1.77%). Of those with a 12-month prevalence diagnosis, 34.6% had one or more comorbid psychiatric disorders. Most notably, ADHD had comorbidity rates of 25.15% with ODD, 18.18% with CD, 6.38% with GAD, and 3.66% with MDD. Conclusions: Psychiatric disorders are common in Chinese children and adolescents. Being the most prevalent mental disorder, ADHD requires continued focus and support in awareness and education.

description: The improvement of traffic efficiency at urban intersections receives strong research interest in the field of automated intersection management. So far, mostly non-learning algorithms like reservation or optimization-based ones were proposed to solve the underlying multi-agent planning problem. At the same time, automated driving functions for a single ego vehicle are increasingly implemented using machine learning methods. In this work, we build upon a previously presented graph-based scene representation and graph neural network to approach the problem using reinforcement learning. The scene representation is improved in key aspects by using edge features in addition to the existing node features for the vehicles. This leads to an increased representation quality that is leveraged by an updated network architecture. The paper provides an in-depth evaluation of the proposed method against baselines that are commonly used in automatic intersection management. Compared to a traditional signalized intersection and an enhanced first-in-first-out scheme, a significant reduction of induced delay is observed at varying traffic densities. Finally, the generalization capability of the graph-based representation is evaluated by testing the policy on intersection layouts not seen during training. The model generalizes virtually without restrictions to smaller intersection layouts and within certain limits to larger ones.

Factors linked to employees’ preferences for teleworking: a mixed-methods study of UK employees.
Creators: name: Chiiachenko, Kateryna
Publisher: name: London South Bank University
Year: 2024

description: Background: Teleworking has become more common since Covid-induced restrictions. While many employees enjoy teleworking, 17% prefer returning to the office full-time. This creates a potential conflict between teleworkers who would like to return to the office and employers who wish to expand teleworking practices. To address this, understanding the factors that influence teleworking preferences is important.
Aims: This thesis investigates factors influencing teleworking preference among UK white-collar employees, aiming to develop a valid and reliable tool for measuring teleworking preference predictors. It also seeks to enhance conceptual understanding using Mokhtarian and Salomon's (1994;1995) Model of Telecommuting Adoption as a reference.
Methods: The research includes a narrative review of teleworking literature, a meta-aggregative review of qualitative teleworking-related studies, a qualitative study of 21 UK white-collar teleworkers, and the development and validation of a teleworking preference predictors (TPP) scale involving 310 white-collar teleworkers.
Results: The meta-aggregative review identified four cross-study generalisations which were advantages and disadvantages of teleworking, factors influencing teleworking experiences, and Covid-induced restrictions impact. In the qualitative study the following themes were created: benefits of teleworking, drawbacks of teleworking, adaptation to teleworking, and importance of voluntariness. The TPP scale had content validity, face validity, construct validity, internal reliability, and split-half reliability established. After the EFA analysis, final 28 items and four factors explained 38% of the teleworking preference variance.
Conclusions: Teleworking preference is positively influenced by saved costs and time, reduced stress, increased productivity, avoidance of unwanted social situations, ability to pursue personal interests, and voluntariness. Negative teleworking preference influences include communication difficulties, reduced trust, lack of financial support from employers,

description: Während der Dezellularisierung werden Zellen und antigenes Material aus Gewebe oder Organen entfernt, sodass nur noch die weniger immunogene extrazelluläre Matrix erhalten bleibt. Da diese Matrix die Struktur des Organs erhält, eignet sie sich optimal für die Rebesiedlung mit Zellen, auch anderen Ursprungs. Im Rahmen der vorliegenden Arbeit wurde die Technik der De- und Rezellularisierung für abdominelle Gewebe (i.e. extrahep. Gallengang) und Organe (i.e. Leber, Pankreas) etabliert und optimiert. Hierbei wurde die Dezellularisierung von Ratten- und Schweinelebern durch die Anwendung von oszillierenden Umgebungsdruckschwankungen optimiert. Mittels ex vivo Perfusion von rebesiedelten Rattenlebern und Analyse der Konstrukte zu verschiedenen Zeitpunkten wurde die Entwicklung der Morphologie und Funktion der Konstrukte nach erfolgreicher Rebesiedlung analysiert. Außerdem wurde ein endokrines Neo Pankreas generiert durch Rebesiedlung von dezellularisierten Rattenpankreata mit Langerhans Inseln. Die Funktion dieser grafts wurde durch Glukose-stimulierte Insulin Sekretionstests nachvollzogen.
description: During decellularization, cells and antigenic material is removed from tissue or organs and only the less immunogenic extracellular matrix is conserved. This matrix conserves the architecture of the organ and thus can be used as a biomatrix for the repopulation with cells from a different origin. We established and optimized the technique for abdominal tissue (i.e. extrahepatic bile duct) and organs (i.e. liver and pancreas). Rat and pig liver decellularization was optimized by the application of oscillating pressure changes during the process. The morphology and function of recellularized rat livers was analyzed by ex vivo perfusion and analysis of the grafts at different time points. Furthermore, we generated an endocrine Neo Pancreas by repopulating decellularized rat pancreata with islets of Langerhans. Graft function was analyzed by Glucose stimulated Insulin secretion

description: This thesis comprises of two parts. The first part is the determination of vapor-liquid equilibrium data at atmospheric pressure and 55°C for the ternary system n-hexane-ethyl alcohol-benzene and for the three possible binary systems n-hexane-ethyl alcohol, n-hexane-benzene and ethyl alcohol-benzene which constituted the ternary system. A modified Gillespie equilibrium still is employed to conduct the investigation. The equilibrium data for the three binary systems and the ternary system appear to be consistent as shown from the thermodynamic consistency tests. The experimental results indicate that two binary systems, namely, n-hexane-ethyl alcohol and ethyl alcohol-benzene form azeotrope at 760 nm. Hg. and 55°C. The ternary system deviates considerably from ideal liquid phase behavior. However, no ternary azeotrope is found from the experiment. The second part presents a method for predicting binary vapor-liquid equilibrium data at various conditions if the equilibrium data for the system concerned are available over the complete concentration range at any one isothermal or isobaric condition. The proposed method is limited to nonazeotropic solutions.

description: Background
Bioaccumulating contaminants in surface waters are preferably monitored in fish for assessing the related risks to and via the aquatic environment. Consequently, the European Water Framework Directive (WFD) requires a monitoring of certain priority substances such as mercury, polybrominated diphenyl ethers (PBDE), perfluorooctane sulfonic acid and its derivatives (PFOS), hexachlorobenzene (HCB), hexabromocyclododecanes (HBCDD) and polychlorinated dioxins/dioxin-like compounds (dioxins) in freshwater and coastal fish. Tissue levels have to comply with biota environmental quality standards (EQSs) given in Directive 2013/39/EU. EQSs are justified either by risks for human health (assessed on the basis of fillet) or secondary poisoning of wildlife (based on whole fish). To support the practical implementation of the WFD biota monitoring in Germany, comparative investigations of target fish species caught at six sites were performed.Results
At each site, at least three fish species listed in a national guidance document were sampled (e.g., chub, roach, bream, perch). Beside biometric data, concentrations of seven priority substances were determined in pooled fillet and carcass samples and whole fish data were calculated. The EQSs for PBDE and mercury were exceeded in nearly all fillet and whole fish samples. PFOS was above the EQS at several sites especially in perch, while HCB exceeded the EQS only at one site (Elbe River). All fillet and whole fish samples complied with the EQSs for dioxins and HBCDD. Based on wet weight concentrations of a homogeneous set of 20 composite sample pairs of 3â€Ì5 year-old fish, the following fillet-to-whole fish conversion factors were derived: mercury 0.81, PBDE 5.4, HCB 3.6, PFOS 2.7, dioxins 5.3, and HBCDD 1.8.Conclusions
Recommendations on selection of target fish species, age or tissue given by EU and national guidance documents are practical and feasible. However, further adjustments of the samplings such as the determination of site-specific length-age relationships are required from both ecological and risk assessment perspectives. The derived conversion factors allow the translation of fillet-to-whole fish concentrations (and vice versa), and thus the EQS compliance assessment for the appropriate tissue (fillet for human health, whole fish for wildlife risks) if only one tissue is investigated.

description: Background Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most important infectious agents for the swine industry worldwide. Zinc (Zn) salts, which are widely used as a dietary supplement in swine nutrition, have shown antiviral effects in vitro as well as in vivo. The purpose of this study was to determine the influence of dietary zinc oxide supplementation on vaccination and challenge infection with PRRSV. Findings The clinical course of PRRS and the success of vaccination with an experimental inactivated vaccine were compared between animals receiving a conventional diet (50 ppm Zn, control group) and diets supplemented with Zn oxide (ZnO) at final Zn concentrations of 150 or 2,500 ppm. Pigs receiving higher dietary Zn levels showed a tendency towards higher neutralizing antibody levels after infection, while dietary Zn levels did not substantially influence the number of antiviral IFN-gamma secreting cells (IFN-gamma-SC) or percentages of blood immune cell subsets after infection. Finally, feeding higher dietary Zn levels reduced neither clinical symptoms nor viral loads. Conclusions Our results suggest that higher levels of dietary ZnO do not have the potential to stimulate or modulate systemic immune responses after vaccination and heterologous PRRSV infection to an extent that could improve the clinical and virological outcome.
Experimental and Theoretical Investigation of Ligand Effects in Ruthenium-Catalyzed Olefin Metathesis

description: Olefin metathesis, a powerful means of assembling carbon frameworks, was recognized with the 2005 Nobel Prize in Chemistry. Metathesis catalyst RuCl(OC6Br5)(IMes)(py)(=CHPh) (C) exhibits outstanding performance in macrocyclization and enyne metathesis. This thesis established the trans-anionic geometry of C, and undertook a computational study of its cycloaddition behaviour relative to models RuCl 2L(PMe3)(=CH2) (A: L = PMe3 , B: IMe). Both A and B undergo loss of a stabilizing Cl-Ru pi-donation during cycloaddition, but this is almost completely compensated for in B by enhanced Cl-Ru electrostatic attraction (a consequence of the poor charge-donor capacity of the NHC ligand, which results in a more electropositive Ru center). This poor donor capacity is also important in C, as the NHC ligand is unable to offset the electron-withdrawing effect of the aryloxide. Instead, stronger ethylene binding results. This flattens the energy profile for cycloaddition, accounting for the very high reactivity of C once initiation has commenced.

description: Elemental Carbon (EC) has a significant impact on human health and climate change. In order to evaluate the size segregation of EC emission in the EUCAARI inventory and investigate its influence on the simulation of EC long-range transportation in Europe, we used the fully coupled online Weather Research and Forecasting/Chemistry model (WRF-Chem) at a resolution of 2 km focusing on a region in Germany, in conjunction with a high-resolution EC emission inventory. The ground meteorology conditions, vertical structure and wind pattern were well reproduced by the model. The simulations of particle number and/or mass size distributions were evaluated with observations at the central European background site Melpitz. The fine mode particle concentration was reasonably well simulated, but the coarse mode was substantially overestimated by the model mainly due to the plume with high EC concentration in coarse mode emitted by a nearby point source. The comparisons between simulated EC and Multi-angle Absorption Photometers (MAAP) measurements at Melpitz, Leipzig-TROPOS and Bösel indicated that the coarse mode EC (ECc) emitted from the nearby point sources might be overestimated by a factor of 2-10. The fraction of ECc was overestimated in the emission inventory by about 10-30 % for Russia and 5-10 % for Eastern Europe (e.g., Poland and Belarus). This incorrect size-dependent EC emission results in a shorter atmospheric life time of EC particles and inhibits the long-range transport of EC. A case study showed that this effect caused an underestimation of 20-40 % in the EC mass concentration in Germany under eastern wind pattern.Quelle: http://www.atmos-chem-phys.net

description: Measuring the volume of bird eggs is a very important task for the poultry industry and ornithological research due to the high revenue generated by the industry. In this paper, we describe a prototype of a new metrological system comprising a 3D range camera, Microsoft Kinect (Version 2) and a point cloud post-processing algorithm for the estimation of the egg volume. The system calculates the egg volume directly from the egg shape parameters estimated from the least-squares method in which the point clouds of eggs captured by the Kinect are fitted to novel geometric models of an egg in a 3D space. Using the models, the shape parameters of an egg are estimated along with the egg’s position and orientation simultaneously under the least-squares criterion. Four sets of experiments were performed to verify the functionality and the performance of the system, while volumes estimated from the conventional water displacement method and the point cloud captured by a survey-grade laser scanner serve as references. The results suggest that the method is straightforward, feasible and reliable with an average egg volume estimation accuracy 93.3% when compared to the reference volumes. As a prototype, the software part of the system was implemented in a post-processing mode. However, as the proposed processing techniques is computationally efficient, the prototype can be readily transformed into a real-time egg volume system.
The etiology of adolescent suicide with special reference to the role of firearms and other opportunity-related factors.

Subjects: subject: Psychology, Behavioral.

description: In recent decades, throughout the industrialized world, youth have shown an increasing vulnerability to self-destruction. This thesis supports research which argues that modifying the availability of firearms could act as an immediate approach to the prevention of adolescent suicide. I add to existing psychological and sociological theories, which fail to address the issue of opportunity and the situational factors around an adolescent taking their life, by focusing not only on theory but on the empirical research upon which the validity of these and subsequent theories must depend. I argue that the explanations for suicidal behaviour must, in general, depend on an interactional theory in which socialization, cognitive, intrapsychic, biological factors and opportunity all play a part. For the purposes of this thesis, I have used a cross-section of studies that include the four primary methods of studying the epidemiology of suicide, including: (1) profile analyses; (2) restrospective and prospective investigations of patients who come to clinical attention on account of attempted suicide; (3) cohort analyses; and (4) psychological autopsies of suicides.

description: In order to better understand the kinetics of gas phase bimolecular exchange reactions a computer program has been written which allows easy exploration of the time dependent and vibrational level dependent details of this class of reactions. BIMSIM (for BIMolecular exchange reaction SIMulation) is intended as a very flexible "virtual laboratory" which can easily be configured and reconfigured for a wide range of different experiments (e.g., laser pulse or shock tube), different initial conditions (e.g., of temperature, reactant concentration, and molecular environment), for different reactions in this class, and for different levels of approximation. In order to test the validity and demonstrate the use of the program a reaction system was found for which appropriate input data is available and for which suitably detailed analytical calculations have been done. Agreement was found to be excellent. Using BIMSIM, results of chemical interest were obtained for the reaction Br + HCl $\to$ HBr + Cl. It was found that non-equilibrium depletion of the vibrational levels of HCl are as much as a factor of 10 and that they depend on the relative amounts of Br, HCl and inert diluent He, as well as on the temperature, becoming more pronounced around 500 K. Interesting details of the time dependence of the fractional level populations are discussed.

description: The mouse is the main model organism used to study the functions of human genes because most biological processes in the mouse are highly conserved in humans. Recent reports that compared identical transcriptomic datasets of human inflammatory diseases with datasets from mouse models using traditional gene‐to‐gene comparison techniques resulted in contradictory conclusions regarding the relevance of animal models for translational research. To reduce susceptibility to biased interpretation, all genes of interest for the biological question under investigation should be considered. Thus, standardized approaches for systematic data analysis are needed. We analyzed the same datasets using gene set enrichment analysis focusing on pathways assigned to inflammatory processes in either humans or mice. The analyses revealed a moderate overlap between all human and mouse datasets, with average positive and negative predictive values of 48 and 57% significant correlations. Subgroups of the septic mouse models (i.e., Staphylococcus aureus injection) correlated very well with most human studies. These findings support the applicability of targeted strategies to identify the optimal animal model and protocol to improve the success of translational research.
Understanding the Power of Local Government and the Motivation of Construction Organisations to Drive Low Carbon Outcomes Beyond Minimum Standards
Creators: name: Bedggood, Juliana
Publisher: name: Swinburne
Year: 2024

description: This research developed a framework for the proactive implementation of low carbon outcomes beyond minimum standards in large development projects. The framework comprises the following components: motivating construction organisations, local governments' influential power, and a corresponding suite of strategies aligned with the first two components. This framework will be useful in practice towards guiding the transformation towards low carbon outcomes beyond minimum standards as a new benchmark standard in the built environment. This framework could find utility across many other countries too and thus if implemented, will contribute towards a substantive drop in emissions in the built environment in the future.

description: Häufig genannte Ziele einer Service-orientierten Architektur (SOA) sind die bessere Unterstützung und Anpassbarkeit von Geschäftsprozessen sowie das Business-IT-Alignment. Diese Ziele werden heute nicht erreicht, da die bei der Implementierung eines Fachprozesses notwendigen komplexen Transformationen in einen ausführbaren Workflow schwer nachvollziehbar sind. Dadurch gehen fachliche Anforderungen verloren und es entsteht ein hoher Aufwand bei späteren Prozessanpassungen. Dieser Beitrag führt die Ebene des Systemmodells zwischen Fachbereich (Fachmodelle) und IT-Bereich (ausführbare Modelle) ein, um Geschäftsprozess-Transformationen besser zu unterstützen und den Ergebnisprozess mit den Fachbereichen abstimmen zu können. Im vorgestellten Ansatz wird ein sog. Abbildungsmodell eingeführt, das Zugehörigkeiten von Aktivitäten des Fachmodells zu denen des Systemmodells (d.h. technische Spezifikation des Informationssystems) explizit dokumentiert. Dadurch werden im Software-Entwicklungsprozess automatisierte Konsistenzprüfungen zwischen den Modellebenen möglich. Werden später Prozessanpassungen erforderlich, lassen sich die zu einer fachlichen Aktivität gehörenden technischen Aktivitäten unmittelbar erkennen, was die Durchführung der Anpassung erleichtert. Ein wesentlicher Vorteil unseres Ansatzes besteht darin, dass die Erstellung des Abbildungsmodells nur einen minimalen Aufwand verursacht, da keine komplexen Regeln, sondern nur einfache Beziehungen definiert werden müssen. Der Ansatz ist damit in der Praxis gut verwendbar, was durch eine prototypische Umsetzung unterstrichen wird.

description: This paper is the second in a pair of papers presenting data release 1 (DR1) of the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS), the largest single open-time key project carried out with the Herschel Space Observatory. The H-ATLAS is a wide-area imaging survey carried out in five photometric bands at 100, 160, 250, 350 and 500 μm covering a total area of 600 deg2. In this paper, we describe the identification of optical counterparts to submillimetre sources in DR1, comprising an area of 161 deg2 over three equatorial fields of roughly 12 × 4.5 deg centred at 9h, 12h and 14{^h.}5, respectively. Of all the H-ATLAS fields, the equatorial regions benefit from the greatest overlap with current multi-wavelength surveys spanning ultraviolet (UV) to mid-infrared regimes, as well as extensive spectroscopic coverage. We use a likelihood ratio technique to identify Sloan Digital Sky Survey counterparts at r < 22.4 for 250-μm-selected sources detected at ≥4σ (≈28 mJy). We find `reliable' counterparts (reliability R ≥ 0.8) for 44 835 sources (39 per cent), with an estimated completeness of 73.0 per cent and contamination rate of 4.7 per cent. Using redshifts and multi-wavelength photometry from GAMA and other public catalogues, we show that H-ATLAS-selected galaxies at z < 0.5 span a wide range of optical colours, total infrared (IR) luminosities and IR/UV ratios, with no strong disposition towards mid-IR-classified active galactic nuclei in comparison with optical selection. The data described herein, together with all maps and catalogues described in the companion paper, are available from the H-ATLAS website at www.h-atlas.org.

description: Background Assessment of disability-adjusted life years (DALYs) resulting from non-communicable diseases (NCDs) requires specific calculation methods and input data. The aims of this study were to (i) identify existing NCD burden of disease (BoD) activities in Europe; (ii) collate information on data sources for mortality and morbidity; and (iii) provide an overview of NCD-specific methods for calculating NCD DALYs. Methods NCD BoD studies were systematically searched in international electronic literature databases and in grey literature. We included all BoD studies that used the DALY metric to quantify the health impact of one or more NCDs in countries belonging to the European Region. Results A total of 163 BoD studies were retained: 96 (59%) were single-country or sub-national studies and 67 (41%) considered more than one country. Of the single-country studies, 29 (30%) consisted of secondary analyses using existing Global Burden of Disease (GBD) results. Mortality data were mainly derived (49%) from vital statistics. Morbidity data were frequently (40%) drawn from routine administrative and survey datasets, including disease registries and hospital discharge databases. The majority (60%) of national BoD studies reported mortality corrections. Multimorbidity adjustments were performed in 18% of national BoD studies. Conclusion The number of national NCD BoD assessments across Europe increased over time, driven by an increase in BoD studies that consisted of secondary data analysis of GBD study findings. Ambiguity in reporting the use of NCD-specific BoD methods underlines the need for reporting guidelines of BoD studies to enhance the transparency of NCD BoD estimates across Europe. © The Author(s) 2022

Publisher: name: Springer International Publishing
Year: 2018

description: Canada has a long history of online and distance education, but until 2017 there had been no comprehensive national data on online enrolments in both the university and college sectors. However, in 2017 a team of independent Canadian researchers, working in collaboration with the Babson Survey Research Group and WCET in the USA, raised the funding and conducted a national survey of online learning in all public post-secondary institutions in Canada. The results from the survey are presented and discussed, as well as plans for further studies in the future.
