COPULA REPRESENTATIONS FOR THE SUM OF DEPENDENT RISKS: MODELS AND COMPARISONS
Authors: Navarro Jorge , Sarabia José María
Published: December 2020

The study of the distributions of sums of dependent risks is a key topic in actuarial sciences, risk management, reliability and in many branches of applied and theoretical probability. However, there are few results where the distribution of the sum of dependent random variables is available in a closed form. In this paper, we obtain several analytical expressions for the distribution of the aggregated risks under dependence in terms of copulas. We provide several representations based on the underlying copula and the marginal distribution functions under general hypotheses and in any dimension. Then, we study stochastic comparisons between sums of dependent risks. Finally, we illustrate our theoretical results by studying some specific models obtained from Clayton, Ali-Mikhail-Haq and Farlie-Gumbel-Morgenstern copulas. Extensions to more general copulas are also included. Bounds and the limiting behavior of the hazard rate function for the aggregated distribution of some copulas are studied as well.
Marking one’s own viewpoint: The Finnish evidential verb+kseni‘as far as I understand’ construction
Authors: Jaakola Minna
Published: December 2020

This article examines evidentiality in the frame of inferential adverbs in written interaction from the perspective of Finnish, a language that does not have evidentiality as a grammatical category. The analysis focuses on six adverbs, such askäsittääkseni‘as far as I understand’ andtietääkseni‘to my knowledge, as far as I know’. Evidentiality and epistemic modality intertwine in their semantics, as these adverbs represent a writer’s access to information, but also indicate her evaluation of its reliability. First, this article offers a description of the interactional functions of these adverbs such as marking a writer’s opinion in contrasts, expressing slight hedging in order to anticipate corrections, to allow space for other opinions, or to create irony. Second, in the framework of cognitive grammar, the analysis focuses on the meaning of the evidential verb+kseniconstruction and the effect of different verb stems on it. These adverbs share similar functions in texts, which is due to their flexible constructional meaning. While varying from lexeme to lexeme, specific evidential and epistemic dimensions can either be foregrounded and relevant in a situation or remain backgrounded and not activated.
The United Nations at Seventy-Five: Passing the COVID Test?
Authors: Özler Ş. İlgü
Published: December 2020

The complex issues of the twenty-first century cannot be addressed by disparate actors in the global arena. This has become even more apparent in 2020, as we celebrate the seventy-fifth anniversary of the UN and have witnessed the outbreak of the global COVID-19 pandemic. The pandemic has put the UN system to the test, demonstrating weaknesses in regard to peace and security, sustainable socioeconomic development, and human rights, the three core mission areas of the organization. The underlying tensions between the ideals of liberalism associated with the UN's human rights and socioeconomic-development agendas and the institution of sovereignty, under nationalist strongman leaders throughout the world, stood in the way of an effective response. This is especially true as powerful states are able to thwart collective action in favor of their own perceived national interests. While the UN and its affiliated agencies, such as the World Health Organization, are still able to foster cooperation, their success is limited by the organization's inability to establish some form of authority and command.
Seed enhancement technologies to improve germination and emergence of Australian native Poaceae
Authors: Beveridge Fernanda Caro , Williams Alwyn , Adkins Steve W.
Published: December 2020

Using seeds to restore natural ecosystems has a greater chance of success if the seeds used are ready to germinate given appropriate environmental conditions. For Australian native Poaceae species, seed quality and dormancy can impose constraints on restoration success. In this study, germination biology of three Australian native Poaceae species, such asCymbopogon refractus,Capillipedium spicigerumandBothriochloa bladhii, was investigated. The seeds were exposed to different germination-enhancing chemicals (GECs, namely smoke water (SW), potassium nitrate (KNO3) or a combination (SW + KNO3)) and treated with three different seed enhancement technologies (SETs, namely seed priming, seed coating or seed cookies) then sown into two contrasting soil types (sodosol or black vertisol). Laboratory germination percentages achieved were <50% for all species, limited by dormant seeds. Incorporating GECs together with seed priming or seed coating treatment significantly increased seedling emergence rates and promoted earlier emergence as compared to the untreated control. ForC. refractusandC. spicigerum, priming and/or coating with KNO3+ SW had the highest cumulative emergence. ForB. bladhii, total seedling emergence was the highest (36% in both soils) for primed seeds with KNO3. Seedling emergence from seed cookies was low in all three species (<15%). Generally, soil type did not influence emergence rates for either GEC or SET. Understanding the environmental requirements needed for seed germination, together with an appropriate pre-treatment before sowing, can speed up seedling emergence and increase total emergence when using native Poaceae species for seed-based restoration.
The comparison between CBT focused on perfectionism and CBT focused on emotion regulation for individuals with depression and anxiety disorders and dysfunctional perfectionism: a randomized controlled trial
Authors: Mahmoodi Mohammad , Bakhtiyari Maryam , Masjedi Arani Abbas , Mohammadi Abolfazl , Saberi Isfeedvajani Mohsen
Published: December 2020

Background:

There is considerable evidence indicating that similar aetiological and maintenance processes underlie depressive and anxious psychopathology. According to the literature, perfectionism and emotion regulation are two transdiagnostic constructs associated with symptoms of emotional disorders.

Aims:

This study is the first randomized controlled trial comparing the efficacy of cognitive behavioural therapy for perfectionism (CBT-P) and the unified protocol for the transdiagnostic treatment of emotional disorders (UP).

Method:

Seventy-five participants with a range of depressive and anxiety disorders and elevated perfectionism were randomized to three conditions: CBT-P, UP or a waitlist control (WL).

Results:

Repeated measures ANOVA indicated that the treatment groups reported a significantly greater pre–post reduction in the severity of symptoms of disorders, as well as a significantly greater pre–post increase in quality of life, all with moderate to large effect sizes compared with the WL group. Treatment gains were maintained at 6-month follow-up. The CBT-P group reported a significantly greater pre–post reduction in perfectionism compared with UP, and the UP group reported a significantly greater pre–post improvement in emotion regulation compared with CBT-P.

Conclusions:

Findings support CBT for perfectionism and regard UP as efficacious treatments for individuals with depression and anxiety disorders who also have dysfunctional perfectionism. It appears that perfectionism cannot be a serious obstacle to UP. As this is a preliminary study and has some limitations, it is recommended that further research be conducted.

Whistler‐mode chorus emission is important in the scattering and acceleration of electrons and filling of the radiation belts at Jupiter. In this work whistler mode magnetic intensity levels at Jupiter are comprehensively binned and parameterized. The frequency range of whistler mode under study extends from the proton cyclotron frequency, fcH, to fceq/2, where fceq is the cyclotron frequency mapped to the magnetic equator. Parametric dependence of magnetic plasma wave intensity is obtained versus frequency, latitude, and M‐shell, as determined using a current magnetic field model based on Juno data. The results extend similar analyses of Jupiter whistler‐mode emission obtained by the Galileo spacecraft, particularly on the nightside, and provide better coverage in latitude. Peaks in whistler‐mode emission occur near M ∼ 8–9, similar to previous studies, with average peak intensities approaching 10−2 nT2, as also found by Galileo on the dayside. Auroral hiss and probably Z‐mode are observed at higher latitudes. Jovian chorus emissions near an equatorial source region are more broad‐banded than terrestrial chorus, and are coincident with a broad‐banded electron distribution of free energy and strong electron scattering to large pitch angles. Intense whistler mode within a young plasma injection region is also observed, similar to injections in Saturn's magnetosphere. Future study of wave particle interactions within the chorus source region will be important. Possible Z‐mode emission at significant intensity levels is observed in Jupiter's inner magnetosphere, more intense, but not unlike Z‐mode observed at Saturn.

Proton pump inhibitors (PPIs) belong to the most common medication in geriatric medicine. They are known to reduce osteoclast activity and to delay fracture healing in young adult mice. Because differentiation and proliferation in fracture healing as well as pharmacologic actions of drugs markedly differ in the elderly compared to the young, we herein studied the effect of the PPI pantoprazole on bone healing in aged mice using a murine fracture model. Bone healing was analyzed by biomechanical, histomorphometric, radiological and protein biochemical analyses. The biomechanical analysis revealed a significantly reduced bending stiffness in pantoprazole-treated animals when compared to controls. This was associated with a decreased amount of bone tissue within the callus, a reduced trabecular thickness and a higher amount of fibrous tissue. Furthermore, the number of osteoclasts in pantoprazole-treated animals was significantly increased at 2 weeks and decreased at 5 weeks after fracture, indicating an acceleration of bone turnover. Western blot analysis showed a lower expression of the bone morphogenetic protein-4 (BMP-4), whereas the expression of the pro-angiogenic parameters was higher when compared to controls. Thus, pantoprazole impairs fracture healing in aged mice by affecting angiogenic and osteogenic growth factor expression, osteoclast activity and bone formation.

Published: December 2020

Myocardial infarction (MI) is associated with renal alterations resulting in poor outcomes in patients with MI. Renal fibrosis is a potent predictor of progression in patients and is often accompanied by inflammation and oxidative stress; however, the mechanisms involved in these alterations are not well established. Endoplasmic reticulum (ER) plays a central role in protein processing and folding. An accumulation of unfolded proteins leads to ER dysfunction, termed ER stress. Since the kidney is the organ with highest protein synthesis fractional rate, we herein investigated the effects of MI on ER stress at renal level, as well as the possible role of ER stress on renal alterations after MI. Patients and MI male Wistar rats showed an increase in the kidney injury marker neutrophil gelatinase-associated lipocalin (NGAL) at circulating level or renal level respectively. Four weeks post-MI rats presented renal fibrosis, oxidative stress and inflammation accompanied by ER stress activation characterized by enhanced immunoglobin binding protein (BiP), protein disulfide-isomerase A6 (PDIA6) and activating transcription factor 6-alpha (ATF6α) protein levels. In renal fibroblasts, palmitic acid (PA; 50-200 µM) and angiotensin II (Ang II; 10−8 to 10−6M) promoted extracellular matrix, superoxide anion production and inflammatory markers up-regulation. The presence of the ER stress inhibitor, 4-phenylbutyric acid (4-PBA; 4 µM), was able to prevent all of these modifications in renal cells. Therefore, the data show that ER stress mediates the deleterious effects of PA and Ang II in renal cells and support the potential role of ER stress on renal alterations associated with MI.
Three-dimensional continuum radiative transfer of polarized radiation in exoplanetary atmospheres
Authors: Lietzow M. , Wolf S. , Brunngräber R.
Published: December 2020

Context.Polarimetry is about to become a powerful tool for determining the atmospheric properties of exoplanets. For example, recent observations of the WASP-18 system allowed the polarized flux resulting from scattering in the atmosphere of WASP-18b to be constrained. To provide the basis for the interpretation of such observational results and for predictive studies to guide future observations, sophisticated analysis tools are required.

Aims.Our goal is to develop a radiative transfer tool that contains all the relevant continuum polarization mechanisms for the comprehensive analysis of the polarized flux resulting from the scattering in the atmosphere of, on the surface of, and in the local planetary environment (e.g., planetary rings, exomoons) of extra-solar planets. Furthermore, our goal is to avoid common simplifications such as locally plane-parallel planetary atmospheres, the missing cross-talk between latitudinal and longitudinal regions, or the assumption of either a point-like star or plane-parallel illumination.

Methods.As a platform for the newly developed numerical algorithms, we use the 3D Monte Carlo radiative transfer code POLARIS. The code is extended and optimized for the radiative transfer in exoplanetary atmospheres. We investigate the reflected flux and its degree of polarization for different phase angles for a homogeneous cloud-free atmosphere and an inhomogeneous cloudy atmosphere. Our results are compared with already existing results to verify the implementations. To take advantage of the 3D radiative transfer and to demonstrate the potential of the code, the impact of an additional circumplanetary ring on the reflected polarized flux is studied. Therefore, a simple ring model with water-ice particles is used and various inclination angles, optical depths and viewing angles are investigated.

Results.The considered test cases show a good agreement with already existing results. The presence of a circumplanetary ring consisting of small water-ice particles has a noticeable impact on the reflected polarized radiation. In particular, the reflected flux strongly increases at larger phase angles if the planetary orbit is seen edge-on because the considered particles tend to scatter forwards. In contrast, the degree of polarization decreases at these phase angles.

Conclusions.We present a polarization radiative transfer tool in which all relevant contributions to the reflected polarized continuum flux are considered. In a case study, we investigated the impact of a planetary ring on the net polarization signal.

Published: December 2020

We present a compilation of over 1700 focal mechanisms for nearly 1300 earthquakes in metropolitan France and bordering regions of Western Europe. It is based on both published and unpublished sources (articles, reports, observatory websites) for which the focal mechanism solutions have been verified for internal consistency, corrected in cases of minor errors and rejected in cases of major inconsistencies between the parameters. The database, labeled FMHex20, is a first version and should be regularly updated in the future as part of an ongoing effort within the Seismicity Transverse Action of the French Résif research infrastructure. We also present first-order seismotectonic analyses for the whole metropolitan France and for two regions (Western France and Northern Alps-Jura-Vosges) to illustrate how the FMHex20 database can serve as a basis for geodynamic or seismic hazard zonation studies. Combined with complementary datasets, it can improve our understanding of the kinematics of potentially active faults, including in very-low-strain-rate regions as is the case for most of France.
No-gap second-order optimality conditions for optimal control of a non-smooth quasilinear elliptic equation
Authors: Clason Christian , Nhu Vu Huu , Rösch Arnd
Published: December 2020

This paper deals with second-order optimality conditions for a quasilinear elliptic control problem with a nonlinear coefficient in the principal part that is finitely PC2 (continuous and C2 apart from finitely many points). We prove that the control-to-state operator is continuously differentiable even though the nonlinear coefficient is non-smooth. This enables us to establish “no-gap” second-order necessary and sufficient optimality conditions in terms of an abstract curvature functional, i.e., for which the sufficient condition only differs from the necessary one in the fact that the inequality is strict. A condition that is equivalent to the second-order sufficient optimality condition and could be useful for error estimates in, e.g., finite element discretizations is also provided.

Published: December 2020

This report discusses Shor’s quantum factorization algorithm and ρ–Pollard’s factorization algorithm. Shor’s quantum factorization algorithm consists of classical and quantum parts. In the classical part, it is proposed to use Euclidean algorithm, to find the greatest common divisor (GCD), but now exist large number of modern algorithms for finding GCD. Results of calculations of 8 algorithms were considered, among which algorithm with lowest execution rate of task was identified, which allowed the quantum algorithm as whole to work faster, which in turn provides greater potential for practical application of Shor’s quantum algorithm. Standard quantum Shor’s algorithm was upgraded by replacing the binary algorithm with iterative shift algorithm, canceling random number generation operation, using additive chain algorithm for raising to power. Both Shor’s algorithms (standard and upgraded) are distinguished by their high performance, which proves much faster and insignificant increase in time in implementation of data processing. In addition, it was possible to modernize Shor’s quantum algorithm in such way that its efficiency turned out to be higher than standard algorithm because classical part received an improvement, which allows an increase in speed by 12%.
Using a Boolean derivative to evaluate the significance of properties of recognized objects
Authors: Lyutikova L. A.
Published: December 2020

This paper offers an approach for evaluating the significance of individual characteristics of recognized objects. The scope of this approach is not the subject area where objects and characteristics of these objects are specified, but a trained ∑Π - neural network that works correctly on the specified subject area. In this paper, we propose a method for constructing a crucial function based on the weight characteristics of a correctly functioning ∑Π - neuron. A logical derivative is used to evaluate the significance of object characteristics. This makes it possible to track how the decision function will change its value if one or more object characteristics change their value. This will allow us to draw a conclusion about the most important properties of the subject area under consideration.

Authors: Belyakov P. V. , Nikiforov M. B. , Muratov E. R. , Melnik O. V.
Published: December 2020

Optical flow computation is one of the most important tasks in computer vision. The article deals with a modification of the variational method of the optical flow computation, according to its application in stereo vision. Such approaches are traditionally based on a brightness constancy assumption and a gradient constancy assumption during pixels motion. Smoothness assumption also restricts motion discontinuities, i.e. the smoothness of the vector field of pixel velocity is assumed. It is proposed to extend the functional of the optical flow computation in a similar way by adding a priori known stereo cameras extrinsic parameters and minimize such jointed model of optical flow computation. The article presents a partial differential equations framework in image processing and numerical scheme for its implementation. Performed experimental evaluation demonstrates that the proposed method gives smaller errors than traditional methods of optical flow computation.

Methodology for calculating the average time of entry into synchronism of stations of the system of quantum key distribution with sequential polling of fiber-optic line sections with decreasing length by the graphic-analytical method
Authors: Mironov Y , Mironova P , Rumyantsev K
Published: December 2020

A method is proposed for calculating the average time of entry into synchronism of stations of the system of quantum key distribution (QKD) with sequential polling of sections of a fiber-optic communication line (FOCL) with decreasing length. A diagram of states and transitions for a sequential search for a photon pulse is constructed. Analytical expressions are obtained for finding the probability of detecting a photon pulse, the average number of steps for entry into synchronism of stations, the variance of the number of steps and the average time for entry into connection. It is noted that when the FOCL is divided into sections with decreasing length, the level of dark current pulses (DCP) significantly decreases from section to section. The latter allows to reduce the probability of false alarms of the photodetector. The analysis of the results obtained showed that the time of entry into synchronism for the proposed algorithm is 3 times less than the time required for entry into communication of stations in the case of an algorithm-analogue. The results obtained indicate the possibility of increasing the length of the FOCL while ensuring the value of the synchronization error probability at the level of 0.01.

Published: December 2020

The use of information technology in the management of construction projects has become a decisive factor for the successful completion of projects, taking into account time, quality and financial costs. There are challenges in visualizing the planning process and integrating information between stakeholders. The paper considers some aspects of the development trend of information technology in construction. The element base, including the risks arising during the design and construction, associated with the direct use of computer and mathematical models of the object in the design is considered. The generated information models will provide basic information for the participants in the design process, which ultimately will be the basis of the element base of an effective tool for ensuring project life cycle management. The following methods were used: system analysis, logical-mathematical modelling, systems theory, economic-visual modelling, research methods of operations, economic and mathematical methods. A basic block diagram of 4D modelling is presented to minimize the occurrence of risks during design. The model allows considering the possibility of assessing the duration of the project, the level of labour productivity, as well as visualizing the construction process. The presented analysis indicates the importance of using 4D modelling in relation to the life cycle of the object in order to prevent the possibility of construction risks.

Currently, studies on the use in agriculture of microbial preparations based on plant growth-promoting rhizobacteria are of increasing interest. Mutualistic relationships between microorganisms and plants contribute to increasing the productive potential, immune status of crops. Deciphering of the plant microbiome, the search for effective microsymbionts and the introduction of rhizobacteria into the rhizosphere of plants are current and promising research areas for solving the problem of biologization of agricultural technologies for their cultivation. The purpose of the study was to study the effect of associative bacterial strains on the structure of the microbiocenosis of the rhizosphere and the productivity of winter wheat in the conditions of southern chernozem. The effect of strains associated with Triticum aestivum on the structure of the rhizosphere of winter wheat under the conditions of a field experiment on chernozem southern of the steppe zone of Crimea was established. A metagenomic analysis of the rhizosphere of the varieties Ermak and Bagheera showed the presence of 18 phyla. Seven phyla of prokaryotes: Thaumarchaeota, Acidobacteria, Actinobacteria, Bacteroidetes, Firmicutes, Proteobacteria, and Verrucomicrobia were included in the dominant composition (share above 1%). The positive effect of newly isolated strains of bacteria associated with T. aestivum on plant development was shown.

Published: December 2020

Essential oils as a feed additive in animal and poultry nutrition should preserve the bactericidal properties of blood and suppress the formation of bacterial biofilms. The study of bacterial biofilms and bacterial activity of blood serum in broiler chickens against the background of the addition of essential oil of Satureja montana to a diet was discussed in the article. Blood serum of broilers that received essential oil with feed suppressed the growth of the bacterial biofilms at S. aureus test culture by 60-72%. It serum had a weaker effect on the bacterial biofilms at E. coli test culture; it reduced the density by 23.5%. This effect began only after the 10th day of inclusions of essential oil. The blood serum of chickens that received essential oil in the form of aqueous solutions had a weak antimicrobial effect against growing the bacterial biofilms at S. aureus test culture; the density was 10% lower than that of the control. The growth of the bacterial biofilms of E. coli test culture was not inhibited.

Published: December 2020

A multicenter study of the application of the microbiological preparation Embiko® in vineyards with its introduction with drip irrigation in the Western foothill-seaside viticultural zone of Crimea was carried out. Granulometric analysis of the soil showed that in the experimental version with the use of Embiko®, the specific content of its fine fractions increased by 5%, i.e. the soil became looser. The introduction of Embico® in liquid form with drip irrigation gave an increase in yield by 1.3 kg per bush, while the sugar content of the berry juice improved by at least 8%. An antistress effect on plants under the influence of treatment with a biological preparation was also revealed, which manifests itself in a significant functional improvement of the leaf apparatus and an increase in the growth rates of grape shoots. When using the biological preparation Embico®, the profit or net income at the pilot site increased compared with the control option (without application) and, accordingly, the profitability of production increased by 79%.

The purpose of the work is to identify areas for improving the efficiency of corporate governance in the context of the digitalization of the economy. The characteristic features of a corporation as a system, the development of which is influenced by its subsystems and supersystem, have been highlighted and described. It has been shown that the quality of management impact on a corporation depends on how fully the experience of the corporation’s development in the past is taken into account. Adequate forecasting of its possible states in the future is also important. Based on the study of the triad of the processes of development of socio- economic systems (ontogenesis, phylogenesis and technogenesis), it is shown that currently there is an imbalance caused by a sharp acceleration of technogenesis. The dialectical consideration of the triad of developmental processes led to the conclusion that the imbalance was caused primarily by the exacerbation of the contradiction between technogenesis and ontogenesis. As a point of relevance for resolving the revealed contradiction, it is proposed to shift the emphasis in corporate management to phylogenesis. Specific measures for the development of phylogonese in corporations are the introduction and development of new forms of joint activities, the transformation of organizational structures, the creation of an atmosphere of mutual understanding, justice, morality, ethics, and culture.

Today, universities are increasingly perceived as active participants in the processes of regional development and corporate relations, and the role of the University is not limited to educational activities or science and research jobs. Universities are urged to solve the problem of attracting young people to production in order to ensure the normal reproduction and sustainable development of business, and at the same time provide the opportunity to find the place in society for their graduates, to realize their abilities in present dynamic social-economic conditions. The importance of the problem of effective employment of University graduates is also due to the perception of young people in society as the most socially unstable (“explosive”) group. It requires the creation of graduate employment ecosystems, especially in peripheral regions. The ecosystem model proposed in this article, aimed at promoting employment of graduates and creating conditions for their career development, can be used as an information, analytical and infrastructure basis for integrating young people into the labor sphere of life, for expanding the number of stakeholders and harmonizing their interests.

Published: December 2020

In our research, we cover the problem of strategic planning in the modern period within a separate organization. Long-term fixed strategies are losing their relevance in an unstable, constantly modernizing world. During the CAVID-19 crisis, companies realized the need for changes in the direction of digital transformation. Features of digitalization cause the need to form a new strategy of the organization, the implementation of which requires certain actions. The purpose of the study was to justify these actions. After studying the material that makes up the new corporate strategy, we identified the requirements for its implementation with maximum results. The research substantiates the concepts of corporate strategy, corporate culture, digitalization and its features. The results of the research will become recommendations for modern companies in the formation and implementation of corporate strategy.
Assessment of the impact of digitalization on the formation of strategic corporate interests of the company using the apparatus of fuzzy logic
Authors: Kokhanova Viktoriia
Published: December 2020

Faced with the need to implement digital tools / processes, the company is forced to independently calculate not only costs, but also methods and mechanisms for assessing the effectiveness of these innovations. In this situation, it is necessary to choose, among other things, methods and assessment tools, and the use of the apparatus of fuzzy logic can be used as one of the tools. In this article, we give an example of using the apparatus of fuzzy logic, indicate the criteria that can be used as criteria for building a system for assessing the effectiveness of digitalization in order to achieve the strategic corporate interests of the company, and also provide an overview of the available developments. Within the framework of the article, we have also identified the directions of modification of classical assessment methods that are possible using the apparatus of fuzzy logic.

Published: December 2020

Hintergrund Der Stellenwert curricularer Online-Lehre steigt kontinuierlich an, nicht zuletzt gefördert durch die Notwendigkeit digitaler Lehrinhalte während der SARS-CoV-2-Pandemie. An der Universitäts-HNO-Klinik Freiburg bestehen bereits seit 2018 Erfahrungen mit einer interaktiven Lernplattform (HNO-Lernprogramm).

Ziel der Arbeit Die vorliegende Arbeit gibt einen Einblick in Aufbau und Funktionen des HNO-Lernprogramms. Zudem sollen Nutzung und Nutzen des Programms subjektiv und objektiv evaluiert werden.

Material und Methoden Zur Ermittlung von Nutzen und Nutzung führten wir zunächst eine subjektive Befragung mit 116 Studierenden durch. Zur Objektivierung der Ergebnisse zählten wir anschließend die tatsächlichen Zugriffe und führten eine randomisierte Lernkontrollstudie (n = 47) durch.

Ergebnisse Das Lernprogramm wurde von 97 % der befragten Studierenden genutzt. Über 80 % stimmten zu, dass es ihre Prüfungsvorbereitung verbessert, sie zum Lernen motiviert und ihr Interesse am Fach HNO verstärkt habe. In einem Jahr wurden fast 90 000 Zugriffe auf das Programm gezählt. Die Lernkontrollstudie zeigte zudem ein signifikant besseres Testergebnis bei den Teilnehmern, die zusätzlich das Lernprogramm genutzt hatten.

Diskussion Das HNO-Lernprogramm ist ein vielversprechendes E-Learning-Tool, welches in dieser Form ein Alleinstellungsmerkmal aufweist. Interuniversitäre Kooperationen könnten den Ausbau und die Nutzung des Programms auf nationaler Ebene ermöglichen.
