Ultrasound practice is a longstanding tradition for radiology departments, being part of the family of imaging techniques. Ultrasound is widely practiced by non-radiologists but becoming less popular within radiology. The position of ultrasound in radiology is reviewed, and a possible long-term solution to manage radiologist expectations is proposed. An international group of experts in the practice of ultrasound was invited to describe the current organisation of ultrasound within the radiology departments in their own countries and comment on the interaction with non-radiologists and training arrangements. Issues related to regulation, non-medical practitioners, and training principles are detailed. A consensus view was sought from the experts regarding the position of ultrasound within radiology, with the vision of the best scenario for the continuing dominance of radiologists practising ultrasound. Comments were collated from nine different countries. Variable levels of training, practice, and interaction with non-radiologist were reported, with some countries relying on non-physician input to manage the service. All experts recognised there was a diminished desire to practice ultrasound by radiologists. Models varied from practising solely ultrasound and no other imaging techniques to radiology departments being central to the practice of ultrasound by radiologists and non-radiologist, housed within radiology. The consensus view was that the model favoured in select hospitals in Germany would be the most likely setup for ultrasound radiologist to develop and maintain practice. The vision for 20 years hence is for a central ultrasound section within radiology, headed by a trained expert radiologist, with non-radiologist using the facilities. Critical relevance statement The future of ultrasound within the radiology department should encompass all ultrasound users, with radiologists expert in ultrasound, managing the ultrasound section within the radiology department. The current radiology trainees must learn of the importance of ultrasound as a component of the 'holistic' imaging of the patient. Key points: 1. Ultrasound imaging within radiology departments precedes the introduction of CT and MR imaging and was first used over 50 years ago. 2. Non-radiology practitioners deploy ultrasound examinations to either 'problem solve' or perform a comprehensive ultrasound examination; radiologists provide comprehensive examinations or use ultrasound to direct interventional procedures. 3. Radiology does not 'own' ultrasound, but radiologists are best placed to offer a comprehensive patient-focused imaging assessment. 4. A vision of the future of ultrasound within the radiology department is encompassing all ultrasound users under radiologists who are experts in ultrasound, positioned within the radiology department. 5. The current radiology trainee must be aware of the importance of ultrasound as a component of the 'holistic' imaging of the patient. [ABSTRACT FROM AUTHOR]

The German school system employs centrally organized performance assessments (some of which are called "VERA") as a way of promoting lesson development. In recent years, several German federal states introduced a computer-based performance testing system which will replace the paper-pencil testing system in the future. Scores from computer-based testing are required to be equivalent to paper-pencil testing scores so that the new testing medium does not lead to disadvantages for students. Therefore, the current study aimed at investigating the size of the mode effect and the moderating impact of students' gender, academic achievement and mainly spoken language in everyday life. In addition, the variance of the mode effect across tasks was investigated. The study was conducted in four German federal states in 2019 using a field experimental design. The test scores of 5140 eighth-graders from 165 schools in the subject German were analysed. The results of multi-level modelling revealed that students' test scores in the computerized version of the VERA test were significantly lower than in the paper-pencil version. Students with a lower academic achievement were more disadvantaged by the VERA computerized test. The results were inconsistent regarding the interactions between testing mode and students' gender and mainly spoken language in everyday life. The variance of the mode effect across tasks was high. Research into different subjects and in other federal states and countries under different testing conditions might yield further evidence about the generalizability of these results.

Since the first statement of the German Society of Oto-Rhino-Laryngology, hypoglossal nerve stimulation (HNS) is meanwhile an established treatment option for obstructive sleep apnea (OSA). There are three HNS systems available in Germany which differ in their technical details of the underlying comparable basic principle. For the unilateral HNS with respiratory sensing, several comparative studies, high-volume register analysis and long-term reports exist. The continuous HNS without respiratory sensing does not require a sleep endoscopy for indication. For the bilateral continuous HNS as the single partially implantable device, a feasibility study exists. For indication, the assessment of positive airway pressure failure by sleep medicine is crucial, and the decision for HNS should be made in discussion of other treatment options for at least moderate OSA. The implantation center holds primarily responsibility among the interdisciplinary sleep team and is primary contact for the patient in problems. This depicts why structural processes are required to secure outcome quality and minimize the complications. The aftercare of HNS patients can be provided interdisciplinary and by different medical institutions, whereat, minimal reporting standards to document outcome and usage are recommended.

The present paper is the second of a series of publications that aim at investigating relevant directions to turn the nuclear energy density functional (EDF) method as an effective field theory (EFT). The EDF approach has known numerous successes in nuclear theory over the past decades [1] and is currently the only microscopic technique that can be applied to all atomic nuclei. However, the phenomenological character of the EDF method also comes with important limitations, such as the lack of an explicit connection with quantum chromodynamics (QCD). As was argued in the first paper of this series [2], reformulating the EDF framework as an EFT would enable us to overcome these limitations. In particular, path-integral (PI) techniques are suited to achieve such a purpose as they allow us to design numerous non-perturbative approximations and can take Lagrangians possibly derived from EFTs of QCD as inputs. In our previous paper [2], we have illustrated such technical features for diagrammatic PI techniques in a study of the (0+0)-D O(N)-symmetric φ 4 -theory. In the present work, we consider another class of PI techniques, i.e. functional renormalization group (FRG) approaches, that we apply to the same toy model. Despite our explicit interest for the nuclear many-body problem, the presented study is also directed towards FRG practitioners from various fields: technical details are provided for FRG techniques based on 1-particle-irreducible (1PI), 2-particle-irreducible (2PI) and 2-particle-point-irreducible (2PPI) effective actions, coined respectively as 1PI-, 2PI- and 2PPI-FRGs, and the treatment of the O(N) symmetry is also addressed thoroughly. Connections between these various FRG methods are identified as well. [ABSTRACT FROM AUTHOR]

The global trend in manufacturing has shifted from a manufacturing-centric process toward a user-centric process. This has resulted in a shorter lifespan and a high product replacement rate of any consumer product. Germany has introduced the concept of Industry Revolution 4.0 (IR 4.0) to convert manufacturing processes and mechanisms into cyber-physical systems (CPS). Digital factory, being the first step into CPS and IR4.0, is being targeted as the most important evolution of the manufacturing industry. This paper defines digital factories and their differences between other similar domains such as smart factories, CPS, and virtual factories. The requirements and goals of a digital factory are explained in detail to facilitate future digital factory tool developments. Furthermore, the current challenges faced in the implementation of the digital factory are proposed to be approached by adapting an interoperable virtual reality technology. This paper emphasizes the usage of virtual reality (VR) in simulating a digital factory that aids in the decision-making and efficient operation of a manufacturing facility. Furthermore, recommendations gathered from previous studies for developing VR-based digital factory tools are also explained in detail in this paper. [ABSTRACT FROM AUTHOR]

The political participation literature has documented a long-term trend of the normalization of noninstitutional participation that is often equated with the conventionalization of engagement in protest politics. Less is known on the extent to which noninstitutional forms are differentiated by their mobilization context. Population surveys find it difficult to contextualize individual engagement, and on-site surveys point to effects that are hard to generalize. This study fills this gap by emphasizing differentiation and distinguishing participation according to the issue of engagement. It introduces a conceptual distinction between political insiders and outsiders, defined based on the extent to which they are embedded in the organizational landscape of the dominant cleavage dimension. Using an original survey conducted in Germany during the Covid-19 crisis, the analysis demonstrates that general-population surveys are fit to examine issue-specific participation patterns. The results expose an insider and outsider divide, captured by the effect of attitudinal and behavioral indicators, and demonstrates that the two groups are equally likely to participate in noninstitutional forms. However, insiders engage on the established issues of climate and anti-racism, whereas outsiders engage on the new issues of Covid-19 related economic assistance and civil liberties restrictions. In addition, dynamic models reveal that noninstitutional participation is rooted in volatile issue preferences. Overall, the paper argues that participation during the Covid-19 crisis has furthered the trend towards a differentiated protest arena. [ABSTRACT FROM AUTHOR]

Home delivery services require the attendance of the customer during delivery. Hence, retailers and customers mutually agree on a delivery time window in the booking process. However, when a customer requests a time window, it is not clear how much accepting the ongoing request significantly reduces the availability of time windows for future customers. In this paper, we explore using historical order data to manage scarce delivery capacities efficiently. We propose a sampling-based customer acceptance approach that is fed with different combinations of these data to assess the impact of the current request on route efficiency and the ability to accept future requests. We propose a data-science process to investigate the best use of historical order data in terms of recency and amount of sampling data. We identify features that help to improve the acceptance decision as well as the retailer's revenue. We demonstrate our approach with large amounts of real historical order data from two cities served by an online grocery in Germany. [ABSTRACT FROM AUTHOR]

Between 2016 and 2021, Germany's first total diet study was performed to assess the variety of substances humans are exposed to by dietary intake. On a global scale rather unique, the natural radionuclides lead-210, uranium-234, uranium-238, radium-226, and radium-228 should be investigated in over 200 different food samples within that study. This paper serves as a guide how to successfully determine these natural radionuclides in very low concentrations in a variety of samples. Two independent laboratories were involved for comparison to assure the quality of the presented sample pretreatment and analyzing techniques. [ABSTRACT FROM AUTHOR]

Fire statistics mirror the outcome of fire prevention. Most fire statistics in Germany deal with the loss of life, value, and fire department actions (number of interventions, nozzles used, or alarm category like a false alarm). However, these results also represent the safety level the legislator has set through the prescriptive building regulations. The current statistics cannot evaluate the level of fire safety and the fulfillment or necessity of fire safety precautions. Today, expert judgment from firefighters is necessary to fill this gap. Here, we show the first evaluation of fire prevention and hazard protection measures by evaluating 900 potentially harming fires throughout Germany. In contrast to minor fires, these fires have advanced to the extent that they could potentially violate the protection objectives outlined in building regulations. The fire department association developed a questionnaire to evaluate the fire safety level and possibly reduce unnecessary fire safety regulations. One hundred twenty-three fire departments carried out the questionnaire, which are responsible for 25% of the German population. Fire prevention officers of the fire departments went to the scene after the fire was extinguished, and the fire safety concept of the building could be evaluated. We found a high rate of injuries, smoke spread, need for rescue by firefighters, and higher than expected firefighter response times after arrival at the scene. Surprisingly, smoke spread rates correlated with building height and not with building age. It was even possible to assess the risk of multiple casualties. Overall, the questionnaire results give insight into the current level of fire safety in existing buildings. Ways and rates for smoke and fire spread prove the importance of second escape routes and the influence of human misconduct. According to these results, current building code regulations are sufficient to prevent fire spread. On the other hand, smoke spreading is a severe threat to people's safety. For example, the data shown can be applied in Bayes nets or other risk calculations to optimize individual building designs or even governmental building codes concerning fire safety engineering. Based on our observations, science, and building codes, authorities could in the future establish a performance-based building code instead of the current prescriptive code. This paper presents the first approach in Germany to quantify the expert judgment of fire departments and use it as a source of knowledge for fire prevention. [ABSTRACT FROM AUTHOR]

Purpose: Hospital information systems (HIS) play a critical role in modern healthcare by facilitating the management and delivery of patient care services. We aimed to evaluate the current landscape of HIS in the specialty of gynecology and obstetrics in Germany. Methods: An anonymous questionnaire was distributed via the German Society of Gynecology and Obstetrics newsletter in December 2022. The questionnaire covered the domains baseline demographic information, satisfaction with daily use, satisfaction with implementation, and degree of digitization. Results: Ninety-one participants completed the survey. Median age was 34 years; 67.4% (60 of 89) were female, and 32.6% (29 of 89) were male. Of the survey participants, 47.7% (42 of 88) were residents, 26.1% (23 of 91) senior physicians, and 9.1% (8 of 88) medical directors. The degree of digitization of clinical documentation is mainly mixed digital and paper-based (64.0%, 57 of 89) while 16.9% (15 of 89) operate mainly paper-based. The current HIS has been in use on average for 9 years. The median number of different software systems used in daily routine is 4. About 33.7% (30 of 89) would likely or very likely recommend their current HIS to a colleague. Conclusions: The current landscape of HIS in gynecology and obstetrics in Germany is characterized by a high heterogeneity of systems with low interoperability and long service life; thus, many healthcare professionals are not satisfied. There is both a need to enhance and an interest in modernizing the technological infrastructure to meet today's requirements for patient care. [ABSTRACT FROM AUTHOR]

Increasing residential mobility is said to challenge existing social support systems as mobility raises geographic distances between family members. Since family social support is essential for health and well-being, this study investigates whether residential mobility affects familial social support following changes in proximity to family and kin. By applying a stepwise linear regression on data from the German Socio-Economic Panel study, this paper is looking at variations between different residential mobility trajectories regarding social support provision and spatial proximity to family members in Germany over a 10-year period. Our findings show that people who are moving within Germany are receiving significantly more social support from their family and kin, while internationally mobile respondents receive less compared to non-mobile people. Mediation analyses show that proximity to family and kin are accounting for the negative effect of international mobility on social support but cannot explain the positive effect of internal migration.

Purpose: This paper reports on the first evaluation of infertility counselling in Germany. Methods: Sixty-nine infertility counsellors provided feedback via 524 survey sheets and 182 questionnaires were filled in by clients. Results: The results show a high level of satisfaction on behalf of the clients. They valued the emotional support, information, and exploration of family-building options with and without medical assistance and the counsellors' expertise. During counselling, coping with the emotional burden of infertility was an important issue, but in more than half of all counselling sessions, future parental issues were addressed. The group of clients seeking support can be described to be very heterogeneous, and counselling issues comprise a wide range of aspects. Conclusions: This piece of research suggests that the following issues need to be considered to improve infertility counselling. Better integration of counselling in infertility clinics, more awareness for infertility counselling for other medical and non-medical professions Better funding for counselling so that its uptake is not dependent upon the financial resources of clients Awareness for new groups of clients and counselling issues such as single and transgender individuals, co-parenting families There is a need for more research and the development of counselling concepts.

This paper addresses the challenges and solutions in developing a holistic prevention mobile health application (mHealth app) for Germany's healthcare sector. Despite Germany's lag in healthcare digitalization, the app aims to enhance primary prevention in physical activity, nutrition, and stress management. A significant focus is on user participation and usability to counter the prevalent issue of user attrition in mHealth applications, as described by Eysenbach's 'law of attrition'. The development process, conducted in a scientific and university context, faces constraints like limited budgets and external service providers. The study firstly presents the structure and functionality of the app for people with statutory health insurance in Germany and secondly the implementation of user participation through a usability study. User participation is executed via usability tests, particularly the think-aloud method, where users verbalize their thoughts while using the app. This approach has proven effective in identifying and resolving usability issues, although some user feedback could not be implemented due to cost-benefit considerations. The implementation of this study into the development process was able to show that user participation, facilitated by methods like think-aloud, is vital for developing mHealth apps. Especially in health prevention, where long-term engagement is a challenge. The findings highlight the importance of allocating time and resources for user participation in the development of mHealth applications. [ABSTRACT FROM AUTHOR]

Since 2019, a global increase in patients presenting with functional Tourette-like behaviors (FTB) has been observed. This has been related to the exposure of tic-related content in social media, although other factors seem to further fuel this phenomenon. Recently, we, therefore, proposed the term mass social media-induced illness (MSMI) as, in our opinion, this phenomenon constitutes a new type of mass sociogenic illness (MSI) that is in contrast to all recent outbreaks spread solely via social media. In accordance with this hypothesis, we were able to identify the host of the German YouTube channel "Gewitter im Kopf" ("Thunderstorm in the brain") as the initial virtual index case. The purpose of this paper is to present clinical characteristics of a sample of 32 patients diagnosed with MSMI-FTB compared to a large sample of patients with Tourette syndrome (TS) and other chronic tic disorders (CTD) (n = 1032) from the same center in Germany indicating clinical factors helpful to distinguish between tics in TS/CTD and MSMI-FTB. Our main findings were: in patients with MSMI-FTB compared to those with TS/CTD we found (i) a significantly higher age at onset, (ii) a significantly higher rate of females, (iii) a significantly higher rate of obscene and socially inappropriate symptoms, (iv) a significantly lower rate of comorbid ADHD, and (v) a significantly lower rate of OCD/OCB. In contrast, rates of comorbid anxiety and depression as well as reported frequencies of premonitory urges/sensations and suppressibility of symptoms did not differ between groups.

This paper investigates the Maximum Acquisition Values (MAVs) of weeding robots and their determinants in both organic and conventional sugar beet farming in Germany. The MAV is defined in this paper as the price of the weeding robot that renders the same net profit as the current weeding methods. For our analysis, a Monte Carlo simulation approach is used, combined with empirical data and data collected from weeding robot companies. The results show that the MAVs of mechanical weeding robots for organic farming are substantially higher than that of spot spraying robots for conventional farming. Technology attributes are more influential than labour cost in determining the MAVs of weeding robots: in organic farming, technology attributes such as area capacity and weeding efficiency impact the MAVs of mechanical weeding robots the most; in conventional farming, supervision intensity and the robot's ability to save herbicides are the most influential factors. The wage rate of unskilled labour, relevant for manual weeding, plays a more important role in determining the MAVs than that of skilled labour, relevant for supervision of the robot. This implies that a shortage of seasonal workers and hence increases in the wage of low-skilled labour could be important drivers of the adoption of mechanical weeding robots. Plot characteristics such as plot size and mechanisation level only have limited impacts on the MAVs. [ABSTRACT FROM AUTHOR]

The ongoing demographic change in most developed countries consists of two coinciding independent developments that differ in structure and persistence: A slow, monotonic and (presumably) permanent longevity effect caused by an increasing life expectancy; and a more rapidly changing, non-monotonic and less permanent cohort effect caused by fluctuations in the size of cohorts. This paper shows the longevity effect has a positive impact on the rates of return households generate within a pay-as-you-go (PAYG) pension system. The cohort effect, by contrast, results in winners and losers in PAYG systems. The paper additionally shows that the type of PAYG pension system alters the results significantly. Taking the remarkable demographic change in Germany as an example, a large-scale overlapping generation model quantifies rates of return within the PAYG pension system for every cohort. The results show that the two effects combined cause return differentials of almost 1.3 percentage points between generations. [ABSTRACT FROM AUTHOR]

Fire detection and fire alarm systems (FDAS) have the function of warning people swiftly of the hazards of a fire and thus permitting rapid rescue, protecting material assets (particularly where unattended), ensuring operational processes, and preventing fires from spreading, i.e. ensuring early and effective firefighting. In attaining these objectives, installed FDAS contribute substantially to fire protection. In this context, automatic fire detectors have the function of detecting fires early, swiftly and reliably. Fire detectors are sensor systems and form part of a wider safety system. They are exposed to numerous environmental conditions specific to their use and, like other socio-technical systems, undergo natural ageing processes which limit their service lifespan. Owing to the numerous risks that arise when a fire detector fails or its function is impaired, the continuous serviceability of a FDAS must be ensured. This requires controlled replacement of fire detectors. In some countries, this is ensured by standards. This paper explains the need for controlled replacement of fire detectors and the associated causes and effects, with reference to the example of Germany and the provisions of DIN 14675-1. The paper explains, in terms of practical relevance and with reference to examples, the basic concept of preventing possible failure of a technical safety system in order to assure its protective function in the event of a hazard occurring, together with the range of essential causes and effects.

This paper investigates the changes in time use, working conditions and subjective time wealth during the COVID-19 pandemic in Germany. Our analysis draws on panel data collected before and during the first lockdown among 786 employees. It employs a recently developed scale on time wealth which has been suggested as a comprehensive measure to capture the subjective experience of time. We provide separate analyses according to gender and essential occupation. First-difference regressions are applied to examine how changes in time use and changes in working conditions during the lockdown affected subjective time wealth. Our results show a general growth in time wealth during the lockdown which is, among other factors, driven by a decline in work hours and an increase in sleep duration. We also find positive effects on time wealth from decreased time pressure at work, more autonomy in organising one's working day, and an improved reconciliation of work and private life. This study contributes to existing research by identifying key aspects how to improve time wealth among employees. [ABSTRACT FROM AUTHOR]

SEIR (Susceptible–Exposed–Infected–Recovered) approach is a classic modeling method that is frequently used to study infectious diseases. However, in the vast majority of such models transitions from one population group to another are described using the mass-action law. That causes inability to reproduce observable dynamics of an infection such as the incubation period or progression of the disease's symptoms. In this paper, we propose a new approach to simulate the epidemic dynamics based on a system of differential equations with time delays and instant transitions to approximate durations of transition processes more correctly and make model parameters more clear. The suggested approach can be applied not only to Covid-19 but also to the study of other infectious diseases. We utilized it in the development of the delay-based model of the COVID-19 pandemic in Germany and France. The model takes into account testing of different population groups, symptoms progression from mild to critical, vaccination, duration of protective immunity and new virus strains. The stringency index was used as a generalized characteristic of the non-pharmaceutical government interventions in corresponding countries to contain the virus spread. The parameter identifiability analysis demonstrated that the presented modeling approach enables to significantly reduce the number of parameters and make them more identifiable. Both models are publicly available. [ABSTRACT FROM AUTHOR]

In Germany, building codes relating to fire safety are mainly prescriptive nature. Therefore, fire safety engineering is based on a combination of expert judgment and reverse engineering of prescriptive rules. This necessitates to connect the given objectives with the detailed prescriptive rules—if not already described within the law or bylaw. This paper proposes a table relating the fire safety objectives of European building regulations and their German counterpart with the prescriptive model building code in Germany. In addition, a risk curve for prenormative work is also given. This represents the prescriptive regulations concerning in terms of fatalities of a level acceptable to society and emphasizes the lower degree of acceptance of multiple fatalities occurring in a single incident. This residual risk limit represents the opinion of German firefighting associations. Data taken from the London area supports the suggested slope rate, as the level of safety in Britain is similar to that in Germany. The table of prescriptive building regulations and their corresponding objectives aids everyday planning decisions in the context of determining adequate compensation without missing out any essential aspects, such as firefighting and firefighter safety. The proposed table forms the basis of the current discussion of a European model performance-based model building code (PBC) within the European Committee for Standardization CEN. Moreover, the risk curve is the first to be discussed in Germany that takes into consideration the societal aspect. It forms an appropriate basis for performing fire safety risk calculations based on fault tree analysis or Bayes nets. The CEN working group for fire safety engineering discusses both aspects of the current development of a European, performance-based fire safety code. It is presented here for the first time.

In this paper, I study the role of gender-typical parental occupation for young adults' gender-typical university major choice using data on a recent cohort of university students in Germany. Results show significant intergenerational associations between the gender typicality in parental occupation and young adults' majors. As to why these effects occur, findings suggest that the transfer of occupation-specific resources from parents to their children plays an important role and that a transmission of gender roles explains at least some of the father-son associations. The paper contributes to existing literature by introducing a novel measure that operationalises the extent to which majors and occupations are 'typically female' or 'typically male' and by studying different transmission channels.

The paper presents the findings of two recent books on the financial history of the Frankfurt School: Jeanette Erazo-Heufelder, Der argentinische Krösus: Kleine Wirtschaftsgeschichte der Frankfurter Schule, 2017, and Bertus Mulder, Sophie Louisa Kwaak und das Kapital der Unternehmerfamilie Weil. Ein Beitrag zur Wirtschaftsgeschichte der Frankfurter Schule, 2021 (Dutch original 2015). In contrast to the "court histories" of the school, the two authors tell the story of the money that brought the school to life and secured its existence throughout a turbulent period of history. At the center of the books are individuals who have been sidelined until now or even completely ignored by the literature on the Frankfurt School: on the one hand, Felix Weil, who founded and financed the Institute of Social Research and, on the other hand, Erich A. Nadel and Sophie L. Kwaak, two employees of the holding company who managed the accounts of the Weil family and the Institute's foundations and were responsible for protecting the assets from being seized by Nazis. The books' thick descriptions induced the author of the present paper to consider an alternative perspective on the Frankfurt School by contemplating Max Horkheimer and Friedrich Pollock as playing confidential games with Weil and others.

Purpose: This paper presents the results of the first joint survey on the use of SPECT and PET myocardial perfusion imaging (MPI) and cardiac amyloidosis imaging in Austria, Germany, and Switzerland of the year 2021. Methods: A questionnaire was sent in 2022 to centres practicing nuclear medicine. Results: Data from 14 Austrian (10,710 SPECT), 218 German (133,047 SPECT), and 16 Swiss centres (11,601 MPI (6,879 SPECT, 4722 PET)) were analysed. In Austria and Germany, the PET MPI numbers were close to zero and not considered. Official MPS numbers from 2015 to 2021 from Austria and Germany revealed a decline in Austria by about 40% in the pandemic years 2020 to 2021, but an increase in Germany by 9%. Ambulatory care cardiologists represented the major referral group (56–71%). Mostly, stress tests were performed pharmacologically (58–92%). Contrary to Germany, a 1-day protocol was predominant (58–97%) in Austria and Switzerland. The leading camera systems were SPECT-CT in Austria and Switzerland (57–79%) and multi-head systems in Germany (58%). Switzerland had the highest proportion of SPECT MPI with attenuation correction (84%), followed by Austria (43%), and Germany (33%). Electrocardiogram-gated SPECT MPI showed an overall high penetration of 87–99%. Scoring was most frequently applied in Germany (72%), followed by Austria (64%), and Switzerland (60%). Related to the population, the number of cardiac amyloidosis imaging was highest in Austria, followed by Switzerland and Germany. Conclusions: This first joint survey of 2021 shows considerable differences among the countries. The Swiss situation is outstanding due to the wide use of PET MPI. In terms of camera equipment, Switzerland is also leading, followed by Austria and Germany. Despite the differences in procedural issues, the results reveal an overall high standard of MPI imaging.

A cornerstone of well-being research is that the resource-rich are happier with their lives than the resource-poor and better positioned to cope with stressful life events. This paper addresses the role of various resources—human, economic, social, and psychological capital—in life satisfaction during the coronavirus pandemic, using panel data from Germany and the United Kingdom for 2020 and 2021. Cross-sectionally, we find life satisfaction to be clearly related to all these forms of capital, with psychological capital being the strongest predictor of life satisfaction. Longitudinally, the capital endowments in 2020 did not predict changes in life satisfaction within individuals from 2020 to 2021, except for psychological capital. Our results suggest two things: first, the unfolding pandemic did not heighten well-being inequalities; and second, weathering the pandemic required psychological resources in the first place.

Women in academia are typically outnumbered by men, a phenomenon metaphorically known as "the leaky pipeline." This study contributes by showing a motherhood penalty in the career pipeline at the postdoctoral stage in Germany—that is, during habilitation. Based on CV information and an email survey, the paper examines which factors are associated with being awarded a habilitation and whether these factors differ between women and men as well as mothers and fathers. Using Cox regressions of retrospective career trajectories of almost all psychologists at German universities in 2019 (2527 scientists with 37,423 publications), the study shows that SSCI/SCIE articles and having a PhD from abroad increase the habilitation risk more strongly for women and mothers than for men and fathers. Net of career factors observed by CVs, however, mothers have a 42% significantly lower habilitation risk. [ABSTRACT FROM AUTHOR]

Based on anthropological fieldwork among protesters against the Covid policy in Germany, this paper elaborates the symmetry of accusations made against each other by proponents and opponents of the state-imposed protection measures against the backdrop of an asymmetrical distribution of power. The social dynamics that emerged during the pandemic are often understood as the result of a knowledge controversy that most participants thus categorize as a media problem. A key finding of my research on protests against the German Covid policy is that, as in my research on the controversy over mediumism, the controversy is about the agency of human and nonhuman actors and carried out to a great extent based on the same values on both sides, which at the same time accuse each other of not conforming to these values. The protesters are part of a heterogeneous minority that in large parts embodies the values of the majority and, in a way, exceeds them, i.e., a minority that is hypercritical and has extreme expectations about the values of the majority society – in this case: of solidarity, science, transparency, rationality, and coherence. From its marginal position, the minority develops a canny eye for the unfulfilled promises of the majority: its contradictions and conscious or unconscious double standards are perceived as bigotry against the backdrop of the aspiration to absence of contradiction. Therefore, this minority suspects that the motivations and goals behind the measures taken are other than just the protection of health, while the majority in turn see the minority's commitment to society and democracy as (self-)deception and also suspect hidden motives and actors behind it. This mutual suspicion leads to a hysterical state of doubt and distrust, which is rooted in the nature of mediality. [ABSTRACT FROM AUTHOR]

Mental health home treatment is a service where patients with severe mental illnesses are visited by a multiprofessional psychiatric care team at their homes. In Germany, inpatient-equivalent home treatment as a specialized form of home treatment has been offered by hospitals since 2018. In its early stage, the shift of care activities out of the hospital toward the patient's home opened up a new set of problems and blurred the existing boundaries. This ethnographic study follows two home treatment teams and provides an in-depth description of their work. The findings are presented by three themes from our data analysis: (i) closeness and familiarity; (ii) bridging the distance; and (iii) tensions of proximity and distance. We then discuss the findings with the guiding lens of Becoming a Guest, which refers to the ambiguity of proximity and distance. The contribution for computer-supported cooperative work (CSCW) is twofold; on the one hand, we provide a detailed account of mental health home treatment, and on the other hand, we outline a conceptual model that helps to describe and analyze similar cases. We conclude the paper with directions for further research. [ABSTRACT FROM AUTHOR]

SEIR (Susceptible–Exposed–Infected–Recovered) approach is a classic modeling method that is frequently used to study infectious diseases. However, in the vast majority of such models transitions from one population group to another are described using the mass-action law. That causes inability to reproduce observable dynamics of an infection such as the incubation period or progression of the disease's symptoms. In this paper, we propose a new approach to simulate the epidemic dynamics based on a system of differential equations with time delays and instant transitions to approximate durations of transition processes more correctly and make model parameters more clear. The suggested approach can be applied not only to Covid-19 but also to the study of other infectious diseases. We utilized it in the development of the delay-based model of the COVID-19 pandemic in Germany and France. The model takes into account testing of different population groups, symptoms progression from mild to critical, vaccination, duration of protective immunity and new virus strains. The stringency index was used as a generalized characteristic of the non-pharmaceutical government interventions in corresponding countries to contain the virus spread. The parameter identifiability analysis demonstrated that the presented modeling approach enables to significantly reduce the number of parameters and make them more identifiable. Both models are publicly available. [ABSTRACT FROM AUTHOR]

Purpose: The WHO 2016 re-classification of myeloproliferative neoplasms resulted in a separation of essential thrombocythemia (ET) from the pre-fibrotic and fibrotic (overt) phases of primary myelofibrosis (MF). This study reports on a chart review conducted to evaluate the real life approach regarding clinical characteristics, diagnostic assessment, risk stratification and treatment decisions for MPN patients classified as ET or MF after implementation of the WHO 2016 classification. Methods: In this retrospective chart review, 31 office-based hematologists/oncologists and primary care centers in Germany participated between April 2021 and May 2022. Physicians reported available data obtained from patient charts via paper–pencil based survey (secondary use of data). Patient features were evaluated using descriptive analysis, also including diagnostic assessment, therapeutic strategies and risk stratification. Results: Data of 960 MPN patients diagnosed with essential thrombocythemia (ET) (n = 495) or myelofibrosis (MF) (n = 465) after implementation of the revised 2016 WHO classification of myeloid neoplasms was collected from the patient charts. While they met at least one minor WHO-criteria for primary myelofibrosis, 39.8% of those diagnosed with ET did not have histological BM testing at diagnosis. 63.4% of patients who were classified as having MF, however, did not obtain an early prognostic risk assessment. More than 50% of MF patients showed characteristics consistent with the pre-fibrotic phase, which was emphasized by the frequent use of cytoreductive therapy. Hydroxyurea was the most frequently used cytoreductive medication in 84.7% of ET and 53.1% of MF patients. While both ET and MF cohorts showed cardiovascular risk factors in more than 2/3 of the cases, the use of platelet inhibitors or anticoagulants varied between 56.8% in ET and 38.1% in MF patients. Conclusions: Improved histopathologic diagnostics, dynamic risk stratification including genetic risk factors for cases of suspected ET and MF are recommended for precise risk assessment and therapeutic stratification according to WHO criteria.

Shallow-seismic full-waveform inversion (FWI) provides an effective way for the accurate reconstruction of near-surface models. The common 2D shallow-seismic FWI inverts either individual Rayleigh or Love waves, and the joint FWI of Rayleigh and Love waves can further improve the reliability of the result. Conventionally, FWI is formulated as a single-objective inverse problem and is solved with deterministic optimization algorithms. It suffers from a relatively high level of ill-posedness and high computational cost, which are two of the main problems that FWI faces. Recently, a random-objective waveform inversion (ROWI) method is proposed to mitigate these problems. ROWI reformulates waveform inversion as a multi-objective inverse problem and solves it with a stochastic optimization algorithm. The multi-objective framework and the stochastic nature provide ROWI relatively high freedom in searching for the optimal model and therefore improve its robustness against the poor initial model. In this paper, we perform a comprehensive comparison between the performance of shallow-seismic FWI and ROWI for the reconstruction of near-surface models. We compare their performance in the scenario of individual inversion of Rayleigh wave, individual inversion of Love wave, and joint inversion of both wave types. Besides, we also compare their effectiveness when using good and poor initial models. Synthetic examples of a highly heterogeneous model show that ROWI is more efficient and more robust than FWI in both individual and joint inversions. The individual ROWI of Love wave can reconstruct the model more efficiently than Rayleigh wave if a good initial model is available, and the other way around if a poor initial model is provided. The joint inversion, in both FWI and ROWI, outperforms the individual inversion of a single wave type. In both individual and joint inversions, ROWI is more efficient in reducing model error and more robust against the poor initial model than FWI. We also compare the performance of ROWI and FWI by using field data sets acquired in Rheinstetten, Germany. The results show that when a good initial model is available, both FWI and ROWI can nicely reconstruct the main structure of the subsurface model. The validity of the reconstructed model is proved by comparing it to a migrated ground-penetrating radar profile. ROWI can consistently reconstruct the model to a good level even when using a poor initial model, while the individual and joint FWIs fail to work when the initial model is poor. It confirms the relatively higher efficiency and robustness of ROWI than FWI in the reconstruction of near-surface models. [ABSTRACT FROM AUTHOR]

Black people and People of Color are disproportionately affected by racism and show increased rates of psychosis. To examine whether racialized migrant groups are particularly exposed to racism and therefore have higher risks for psychosis, this paper (1) systematically assesses rates of psychosis among racialized migrant groups concerning the country of origin, and (2) analyzes interviews regarding the association of racism experiences with psychosis-related symptoms in racialized Black people and People of Color populations in Germany. We present an umbrella review of meta-analyses that report the incidence of positive symptoms (e.g., hallucinations and delusions) and negative symptoms (e.g., apathy and incoherent speech) of diagnosed schizophrenia, other non-affective psychotic disorders (e.g., schizoaffective disorder) or first-episode psychosis among migrants by country of origin. We also report 20 interviews with first- and second-generation migrants racialized as Black and of Color in Germany to capture and classify their experiences of racism as well as racism-associated mental health challenges. In the umbrella review, psychosis risk was greatest when migration occurred from developing countries. Effect size estimates were even larger among Caribbean and African migrants. In the qualitative study, the application of the constant comparative method yielded four subordinate themes that form a subclinical psychosis symptomatology profile related to experiences of racism: (1) a sense of differentness, (2) negative self-awareness, (3) paranoid ideation regarding general persecution, and (4) self-questioning and self-esteem instability. We here provide converging evidence from a quantitative and qualitative analysis that the risk of poor mental health and psychotic experiences is related to racism associated with minority status and migration.

Universities have increasingly been subjected to policy- and industry demands to produce multi- and interdisciplinary knowledge. This paper explores the extent to which different higher education policy instruments are used to promote interdisciplinarity in teaching and research at universities in the German higher education system comparing them across different federal states. Based on a manifest content analysis of higher education laws and performance agreements with universities in the 16 German states, we were able to distinguish between three types of states: Those a) with a general use of policy instruments aimed at all universities in a state, whereas considerable differences could be observed with regard to the degree of coercion (enabling versus prescriptive provisions) and scope (teaching or research), b) a directed use of policy instrument, targeting specific universities, and c) a hybrid use of policy instruments using both general and directed elements. This paper provides a novel mapping of the promotion of interdisciplinarity in German higher education policies through a variety of policy instruments and hereby contributes to the extant literature on interdisciplinarity in higher education.

In the wake of the coronavirus disease 2019 (COVID-19) pandemic, religious organizations increasingly mediatized their activities. Studies examining this process mostly focused on communal offerings, while ignoring how rapid mediatization affected programs geared toward interfaith dialogue. This paper examines the effects and possibilities of this shift to virtual spaces by focusing on frameworks that promote Jewish–Muslim dialogue in Germany. It traces how Jews and Muslims intervene in popular discourse using social media platforms to self-define their respective religions and the relationship between them. In this process, those involved in creating virtual spaces focused on the intersectionality between gender biases and Christonormativity. This paper utilizes a broad methodological approach, including participant observation in dialogue events in virtual spaces, discursive analyses of videos and podcasts, and qualitative interviews with Jews and Muslims involved in the creation of virtual spaces. The first section discusses Jewish–Muslim encounters occurring in organized dialogue events on video communication platforms that are ephemeral in nature (no recordings). The subsequent sections analyze German-language formats that have a representative character and are streamed, recorded, and presented on social media platforms. [ABSTRACT FROM AUTHOR]

The genus Taxus (yew) is a source of a number of high-value medicinal substances, particularly, paclitaxel (taxol)—a complex diterpenoid compound with a powerful antitumor action (trade name of Taxol®). Paclitaxel is one of the most efficient drugs in chemotherapy owing to its specific ability to suppress proliferation of tumor cells via stabilization of their microtubules. The world-wide demand for taxol is 800–1000 kg a year and these figures annually rise by 20%. The growing need for paclitaxel and its derivatives and the shortage of plant resources necessary for their production made compounds of the taxane group one of the most important objects for development of biotechnological methods of their production. Out of all the possible ways of taxol production (isolation from wild or plantation trees, total chemical synthesis or semisynthesis, use of yew cell cultures, techniques of metabolic engineering, and use of yew endophytic fungi), the most promising is industrial cultivation of Taxus spp. cell cultures. This review examines the papers dealing with investigation of secondary metabolism in dedifferentiated cells in vitro of various yew species and feasibility of industrial use of cell cultures for production of taxoids. We revealed a number of specificity of Taxus spp. cell cultures: (1) from a cytophysiological aspect—difficult initiation of cell cultures, their low growth characteristics, specific media and culturing conditions; (2) from a phytochemical aspect—distinction from intact plants in qualitative composition and content of secondary metabolites accounted for by specificity of cell culture as a biological system; predominant formation of С14-hydroxylated rather than of С13-hydroxylated taxoids; an opportunity for elevation of the content of taxoids—including commercially valuable ones (paclitaxel and baccatin III) with the aid of different tools (elicitation, stress exposures, two-phase cultivation and some others); (3) from a biotechnological aspect—possibility of industrial cultivation of yew cell cultures; existence of several successful industries (Germany and the Republic of Korea).

This paper explores Twitter adoption and social media engagement of private German environmental foundations. The study follows Lovejoy and Saxton's (2012) approach to the hierarchy of social media engagement. It demonstrates the domination of an information provision role on Twitter and the almost equal relevance of action mobilizations and community building posts. At the same time, the study supplements the existing typology with the additional dimension of communication partners addressed in each type of tweet. Finally, using data from interviews, the study interprets and explains the role of social media tweets and patterns of engagement with different groups. In-depth analysis of tweets and interviews with the foundation representatives confirmed a limited use of social media as a means for dialogue and community development. Simultaneously, analysis shows that tweets posted by foundations predominantly address a professional community of other civil society actors, experts and politicians, creating an online expert bubble. Interviews confirmed that such online connections mirror offline cooperation networks that are perceived to be more important for successful communication and project development by the investigated organizations.

Criminological research on COVID-19 and its repercussions on crimes, criminals and law enforcement agencies is still in its infancy. This paper fills that void with regard to the influence of COVID-19 on organized crime and the work of law enforcement agencies' investigations of organized crime in Germany by presenting empirical findings from a nationwide qualitative interview study. Through the methodological combination of Grounded Theory and Situational Analysis, we find three central narratives (us vs. them, nationalization vs. internationalization, conservatism vs. innovation) that were provided by law enforcement personnel in terms of the way in which COVID-19 influenced both organized crime groups and their work in the investigation thereof. Following a reflexive approach, the implications of COVID-19 on the research process itself are also discussed. [ABSTRACT FROM AUTHOR]

Purpose: This paper summarises the results of 4 national surveys on the numbers, utilisation and technique of myocardial perfusion SPECT (MPS) from 2012 to 2021. Methods: A one-page questionnaire for information on MPS in 2012, 2015, 2018 and 2021 was sent to German centres practising nuclear medicine. To check for representativeness, the numbers obtained were related to official annual data and furthermore to the numbers of invasive coronary angiography procedures (ICA). Results: MPS examinations increased by > 40% from 2012 to 2021 and showed a centralisation with increasing MPS per centre. In 2020, a mild impact of the COVID-19 pandemic could be observed in the form of only a slight MPS increase, which was compensated in the following year. Outpatient care cardiologists represent the most important referrer (70%). Mostly, 2-day protocols were used. One-day protocols and stress-only protocols showed insignificant changes. The use of exercise stress decreased steadily. In 2021, exercise stress was replaced by pharmacological stress as the most frequent stress modality. Camera systems showed a shift to more SPECT-CT systems. The use of gated SPECT increased to almost 90%. Quantitative scoring showed an increasing acceptance. The ratio of invasive coronary angiographies (ICA) to MPS was between 3.9 and 4.5. A significant proportion of ICA in the context of CCS (chronic coronary syndrome) was performed without prior testing for ischaemia. Conclusion: The 2012 to 2021 MPS surveys reveal a continuously growing number of examinations with only a mild temporary effect of the COVID-19 pandemic and a centralisation with increasing numbers per centre. Performance and technical data reveal a high-grade adherence of MPS practice to the current ESC guideline. A large potential of non-invasive diagnostics remains for the future.

Anisotropic fast-marching algorithms are computationally efficient tools for generating realistic maps of karst conduit networks, constrained by both the spatial extent and the orientation of karstifiable geologic units. Existing models to generate conduit network maps are limited either by high computational requirements (for chemistry-based models) or by their inability to incorporate the effects of elevation and orientation gradients (for isotropic fast-marching models). The new anisotropic fast-marching approach described here provides a significant improvement, though it imitates rather than reproduces actual speleogenetic processes. It can rapidly generate a stochastic ensemble of plausible networks from basic geologic information, which can also be used as input to karst-appropriate flow models. This paper introduces an open-source, easy-to-use implementation through the Python package pyKasso, then describes its application to a well-mapped geologically complex long-term study site: the Gottesacker alpine karst system (Germany/Austria). Groundwater flow in this system is exceptionally well understood from speleological investigations and tracer tests. Conduit formation primarily occurs at the base of the karst aquifer, following plunging synclines. Although previous attempts to reproduce the conduit network at this site yielded implausible network maps, pyKasso quickly generated networks faithful to the known conduit system. However, the model was only able to generate these realistic networks when the inlet-outlet connections of the system were correctly assigned, highlighting the importance of pairing modeling efforts with field tracer tests. Therefore, a model ensemble method is also presented, to optimize field efforts by identifying the most informative tracer tests to perform. [ABSTRACT FROM AUTHOR]

Backgound: Headache disorders are not only among the most prevalent, they are also among the most disabling disorders worldwide. This paper investigates the association between headache impact on daily life and the socioeconomic status (SES) of headache sufferers. Methods: Data stem from a random general population sample in Germany. Respondents who reported having headache for at least a year and were aged ≥ 18 years were included in the study. A standardized questionnaire addressing headache and headache treatment was filled in during the face-to-face survey. The impact of headache on daily life was measured using the German version of the Headache Impact Test (HIT-6). Results: Higher headache impact was found in low and medium SES compared to high SES. After adjustment for sociodemographics, headache-related factors (analgesic use, headache duration, headache frequency, migraine diagnosis), depressive symptoms, physical inactivity and obesity, an increased odds ratio of having higher headache impact in low SES compared to high SES was found: OR = 1.83, 95% CI [1.43, 2.23], p =.014. When the interactions "SES*obesity", "SES*depressive symptoms", and "SES*physical inactivity" were added, the results showed a significant interaction effect of "SES*obesity". Obese persons with low SES were 3.64 times more likely to have higher headache impact than non-obese persons with low SES. No significant differences between obese and non-obese persons were found in the medium and high SES groups. Conclusions: SES is an important factor that should not be neglected in headache awareness campaigns and headache treatment. Longitudinal studies are needed in the future to investigate whether lifestyle interventions, such as weight reduction, can help to reduce headache impact in people in lower SES.

Since the 1990s, Albania has recognized human dignity as one of the main constitutional principles. However, the national medical jurisprudence regarding informed consent has not been developed as in other Western European Countries. Germany is one of the countries that has a long tradition of protecting human dignity in patient-physician relations.This contribution studies the German law on informed consent to medical treatment, Gesetz zur Verbesserung der Rechte von Patientinnen und Patienten of February 2013 through the application of a case-law study. This law, which codifies the national courts' decisions, highlights the ethical principle of autonomy. In other words, in the absence of a solid national medical jurisprudence, this paper investigates the possibility that Albanian judges could apply the legal arguments of their German colleagues since in the case of case-law study there is an absence of political interference, which can better demonstrate the ethical principle of autonomy and the right to self-determination.

Risk assessment in operative medicine is a key aspect for patient safety. The aim of this paper is to outline the degree of dissemination of a standardized procedure for risk analysis, process-oriented risk analysis, at German university hospitals. Process-oriented risk analysis represents a standardized procedure for the analysis of adverse events within the framework of clinical risk management. In this study, 262 full professors of German university hospitals were surveyed in November 2020 regarding the use of this instrument. The response rate was 17%. The analysis showed that 29% of the respondents already introduced the process-oriented risk analysis in their department. Further, 97% of the respondents were willing to standardize clinical processes with regard to patient safety. Moreover, 95% of the respondents said that a risk analysis and the resulting implementation of new procedural measures were important. It could be shown that the readiness for the procedural consideration of clinical processes with regard to patient safety is 92%. Currently, there is a lack of scientific evidence on the effectiveness and efficiency of the process-oriented risk analysis which is why further studies are needed to achieve a comprehensive understanding of this tool.

Students from a lower socioeconomic background have a higher risk of dropping out of higher education. The underlying mechanisms of this association between socioeconomic background and higher education dropout are not well understood. Previous research in higher education has followed Tinto's model of academic and social integration to explain dropout but has largely neglected social inequality therein. In contrast, social stratification research draws on rational choice theory to explain social inequality in educational attainment but has rarely been applied to explain dropout from higher education. In our paper, we combine these two strands of research. Utilizing data from the National Educational Panel Study (NEPS), we draw on a largescale, representative sample of students in Germany to quantify the relative contribution of each theoretical approach for explaining social inequality in dropout from higher education. Binary logistic regression models reveal that both students' integration and costs-benefit considerations are associated with their dropout risk net of each other. While academic and social integration appears to better predict dropout, rational choice theory accounts for a larger proportion of social inequality therein. We conclude that combining Tinto's model and rational choice theory provides a more comprehensive perspective of dropouts from higher education and social inequality therein. [ABSTRACT FROM AUTHOR]

Individual perceptions of pay satisfaction and pay justice are closely related social indicators. Notwithstanding their apparent resemblance, there are essential theoretical differences between those two concepts. Yet, we know little if people merely consider pay satisfaction and pay justice as two sides of the same coin. This paper theorizes two situations in which people's perceptions of pay satisfaction and pay justice should differ in meaningful ways. First, their pay level should affect people's self-interest and thus have a stronger effect on their pay satisfaction than on pay justice. Second, pay inequality in the workplace should affect people morally and thus should have a stronger effect on their pay justice perception than on pay satisfaction. These hypotheses were tested with linked employer-employee data collected in Germany (N = 2.695). Results of regression analyses with multiple dependent variables show that people's pay satisfaction and pay justice perceptions increased with the level of their individual pay and decreased with the degree of workplace inequality. The pay effect was significantly stronger on pay satisfaction than on pay justice while the workplace inequality effects did not differ significantly. These results suggest that people under specific circumstances differentiate between pay satisfaction and pay justice. Consequently, researchers should consider that their results and conclusions might differ if they analyze pay satisfaction instead of pay justice and vice versa. [ABSTRACT FROM AUTHOR]

The paper reports the results of an exploratory online survey among German, Austrian, and Swiss hospital chaplains (n = 158, response rate 17%) to identify the ethical conflicts they encounter in their work. Respondents indicated that questions surrounding end-of-life care are predominant among the conflicts faced. Chaplains get involved with these conflicts most often through the patients themselves or through nursing staff. Most encounters occur during pastoral care visits rather than in structured forms of ethics consultation such as clinical ethics committees. The results add to the ongoing discussion of chaplains as agents in ethics consultation within healthcare systems as well as their specific role and contribution. [ABSTRACT FROM AUTHOR]

As digitalization in the agricultural sector has intensified, the number of studies addressing adoption and use of digital technologies in crop production and livestock farming has also increased. However, digitalization trends in the context of small-scale farming have mainly been excluded from such studies. The focus of this paper is on investigating the sequential adoption of precision agriculture (PA) and other digital technologies, and the use of multiple technologies in a small-scale agricultural region in southern Germany. An online survey of farmers yielded a total of 2,390 observations, of which 1,820 operate in field farming, and 1,376 were livestock farmers. A heuristic approach was deployed to identify adoption patterns. Probable multiple uses of 30 digital farming technologies and decision-support applications, as well as potential trends of sequential technology adoption were analyzed for four sequential points of adoption (entry technology, currently used technologies, and planned short-term and mid-term investments). Results show that Bavarian farmers cannot be described as exceedingly digitalized but show potential adoption rates of 15–20% within the next five years for technologies such as barn robotics, section control, variable-rate applications, and maps from satellite data. Established use of entry technologies (e.g., automatic milking systems, digital field records, automatic steering systems) increased the probability of adoption of additional technologies. Among the most used technologies, the current focus is on user-friendly automation solutions that reduce farmers' workload. Identifying current equipment and technology trends in small-scale agriculture is essential to strengthen policy efforts to promote digitalization. [ABSTRACT FROM AUTHOR]

Background: The paper examines whether the widespread assumption holds that younger birth cohorts (referred to as Millennials or Generation Y) act as pioneers of changing everyday mobility. Methodology: Based on the time-series dataset "Mobility in Germany" (Mobilität in Deutschland), cohort-specific changes in everyday bicycle and car use that have occurred between 2002 and 2017 are analyzed. The empirical analyses are differentiated by age-group and settlement type. Additionally, socio-structural factors are taken into account. Results: The results show a decline in the predominant everyday use of cars in metropolitan cities, especially among Generation Y. However, the Millennials do not emerge as pioneers of the trend toward predominant bicycle use. The results challenge the assumption that changes in everyday mobility are essentially driven by generational change. [ABSTRACT FROM AUTHOR]

During recent years, maintaining scientific and medical databases has turned out to be a major challenge in the medical sector. The medical data regarding the patients comprise diverse diagnostic medical reports and features for such disease need to be recorded carefully for providing high-quality treatments. Therefore, this paper proposes a hybrid deep convolutional neural network (HDCNN)-based COOT approach to predict the risk of diseases. Initially, an improved crossover-based levy flight optimization algorithm (ICLFDO) algorithm is employed in selecting and processing the unstructured textual data. Then later, the HDCNN-COOT approach predicts the diseases more accurately. In addition to this, the classifier predicts whether the patient is at risk of disease in the future or not. The efficiency of the proposed model is evaluated by using a dataset obtained from University Hospital of Ludwig Maximilian University of Munich, Germany. The data collected in the data center include 29,477,035 data items from 36,082 patients. The proposed model is capable of using structured data and uses textual data of the patients. Finally, the higher classification accuracy and improved performance of the classifiers can be viewed using the experimental results conducted on five different datasets. [ABSTRACT FROM AUTHOR]

Background This paper explores the role of providing structure for students within a new blended-learning family medicine curriculum at Saarland University. This study intends to clarify the role of different structural elements for different learning approaches (deep vs. structured vs. surface learning). Methods This study is based on a mixed-methods approach. Fifth year medical students' (n = 84) learning approaches, measured by a shortened version of the ASSIST questionnaire, were correlated with students' academic performance in state exams and the family medicine exam. Based on learning approaches and age, participants were purposefully sampled into two semi-structured group interviews with seven participants each. Results Although surface approach learning weakly correlated with lower performance in the first state exam (rho = 0.231), surface approach learning did not correlate with lower performance in the family medicine assessment. Based on qualitative results, the structural design of the curriculum seemed to have a high impact on students' satisfaction and motivation to learn. The reduction of extraneous cognitive load was identified as effective in motivating students to study. Deep-learning students highlighted the positive effects of curriculum activities that foster germane cognitive load through schema- based learning. Conclusions Especially for surface approach learners it may be important to provide structured guidance and provide a clear alignment of course content in a blended-learning curriculum, even in higher education. Deep and structured approach learners also benefit from a clear course structure that keeps extraneous cognitive load low and fosters schema acquisition. [ABSTRACT FROM AUTHOR]

This paper explores proculturative semiotic dynamics underlying self-construction in emigration that reveals various forms of the self's positioning through the processes of relating to the native and foreign socio-cultural environments. The self is conceptualised as the heterogeneous entirety of voices and self-related positions which are hierarchically organised. Hierarchical organisation implies the dominance of certain voices and I-positions at the expense of silencing others. Moreover, external societal voices promote hegemonic social representations which are represented as promoter I-positions/signs in the self-structures and have the power to regulate individuals' mental activity. Therefore, it is argued that selves' relations to the environment are not always symmetrically dialogical. The compelling power of hierarchically ordered external meaning systems that are conceptualised as "objective culture" is illustrated in the best manner when a person occurs in emigration where the native organisation of voices and I-positions is being semiotically ruptured due to the meeting with a foreign configuration of a hierarchy of external I-positions and gets "attacked" by alien promoter signs. External promoter voices and I-positions have the power to take the dominant position and establish asymmetric relations with other self-related elements. They can significantly influence intra-psychological negotiations by vocalising hegemonic social representations which exist in any community. The case study of a Georgian emigrant's living in Germany vividly reveals the wave of self-transformations which she undergoes after the liberation from the pressure of native promoter signs and engagement with the German ones. Specific microgenetic experiences leading to the transformations at the ontogenetic level are highlighted. Symmetric and asymmetric forms of communication are conceived as particular instances of relating. This paper vividly reveals the significance of the exploration of the forms of dynamic relations between various components of the self and socio-cultural environment and entailing intra-psychic and external negotiations for better understanding of the nature of humans' epigenetic development.
