User models for multi-context-aware music recommendation
Authors: Pichl Martin , Zangerle Eva 
Published: October 2020

AbstractIn the last decade, music consumption has changed dramatically as humans have increasingly started to use music streaming platforms. While such platforms provide access to millions of songs, the sheer volume of choices available renders it hard for users to find songs they like. Consequently, the task of finding music the user likes is often mitigated by music recommender systems, which aim to provide recommendations that match the user’s current context. Particularly in the field of music recommendation, adapting recommendations to the user’s current context is critical as, throughout the day, users listen to different music in numerous different contexts and situations. Therefore, we propose a multi-context-aware user model and track recommender system that jointly exploit information about the current situation and musical preferences of users. Our proposed system clusters users based on their situational context features and similarly, clusters music tracks based on their content features. By conducting a series of offline experiments, we show that by relying on Factorization Machines for the computation of recommendations, the proposed multi-context-aware user model successfully leverages interaction effects between user listening histories, situational, and track content information, substantially outperforming a set of baseline recommender systems.

Authors: Wiesnagrotzki Nina , Bernreuther Christian , Saeger Wolfgang , Flitsch Jörg , Glatzel Markus , Hagel Christian 
Published: October 2020

Abstract
Purpose
To analyze the co-expression of the intermediate filaments GFAP and cytokeratin in 326 pituitary adenomas with regard to the distribution pattern, the subtype of the adenoma and clinical prognostic data.

Methods
Tissue from 326 pituitary adenomas and 13 normal anterior pituitaries collected in the Institute of Neuropathology, University Medical Center Hamburg-Eppendorf, between 2006 and 2009 was investigated by immunohistochemistry, immunofluorescence and electron microscopy.

Results
Co-expression of intermediate filaments GFAP and cytokeratin was associated with hormone expression in 62/278 cases (22%), but only found in 2/48 (4%) of null cell adenomas (p < 0.01). Simultaneous co-expression of GFAP and cytokeratin in the same cells was demonstrated in 26 out of 326 pituitary adenomas and in all 13 pituitaries. In pituitary intermediate filaments were demonstrated in a larger area of the cytoplasm than in adenoma (p < 0.01), however, overlapping expression was seen in 2.6% of the total area in both, pituitary and adenoma. Congenially, cells with overlapping expression were found near vessels and in follicles. Furthermore, adenomas with cellular co-expression of GFAP and cytokeratin were associated with a lower recurrence rate (7.7%) compared to adenomas without co-expression of intermediate filaments (17.8%).

Conclusions
Cellular co-expression of the intermediate filaments GFAP and cytokeratin in pituitary adenomas and the pituitary was demonstrated and shown to be associated with hormone expression and low recurrence rate. The results are discussed with regard to the biology of folliculostellate cells, neural transformation and tumor stem cells. This study may complement the understanding of pituitary adenoma biology.
Multiparameter assessment of select metal distribution in lacustrine sediments
Authors: Aleksander-Kwaterczak Urszula , Kostka Anna , Leśniak Andrzej 
Published: September 2020

Abstract
Purpose
The main objective of the study was the determination of the Cd, Cr, Cu, Pb, and Zn distribution in Wigry Lake sediments, as well as the contamination and ecotoxicological risk assessment on the basis of a large data set.

Materials and methods
Select metal concentrations were determined via AAS or ICP-MS. Contamination assessment was achieved via the implementation of different geochemical background values, selected pollution indices, and by way of comparison with the limit values of the sediment quality guidelines and supported by cartographic methods.

Results and discussion
Metal concentrations presented in the paper were associated with a specific type of sediment and sedimentation environment. The highest concentrations of metals were found in the fluvial-lacustrine sediment covering the bottom of the bay of eutrophic character. The lowest amounts were found in the lacustrine chalk and clastic sediment present in the littoral parts of the lake, while profundal sediments were more enriched with metals. Studies revealed that the examined metals have mostly natural, but also anthropogenic origin. The assessment of lake sediments, with the use of geochemical background values and different indices, yielded highly diversified results associated with the variability of background values applied in the study. However, ultimately, the Wigry Lake sediments were found to be only slightly contaminated with Cd, Cr, Cu, and Zn, while Pb concentrations were considered to be more disturbing. The potential ecotoxicological risk was assessed as low.

Conclusions
Particular attention in this study was paid to the significance of the geochemical background values adopted for calculations, which, in the case of Wigry Lake, gave very divergent results. A uniquely large data set facilitated the performance of a thorough analysis of metal distributions in recent lacustrine sediments and highlighted the necessity of using integrated approaches in aquatic ecosystem studies.
Faith Assimilated to Perception: the Embodied Perspective
Authors: Kalmykova Elena 
Published: October 2020

AbstractIn this paper, I consider how the embodied approach can be applied to religious faith, and possibly other kinds of faith. I start with the reformed epistemologists’ idea that religious faith is similar to sense perception, and I argue that we can elaborate this idea by taking into account our capability perceptually to grasp what is not accessible by senses—the ‘presence in absence’ (Noë 2012) or, as I call it, perceptual faith. As perception necessarily involves not only a mental but also an embodied relation to its object; an embodied relation can be seen as a constitutive component of faith as well. According to phenomenological accounts of perception (Merleau-Ponty, Noë, Siewert), embodiment and enactment allow humans to transcend perspectival limitations and to perceive an object as it is beyond its appearances: constant despite changes of angle, light, and other conditions and whole even when only parts of it are visible. I argue that, in the same vein, embodied relations and particular normativity involved in perception-based faith allow humans to transcend the precariousness of our experience and to sustain a perception-like relation to religious objects, achieved in a ‘better look’ moments of religious experience. I conclude that an embodied account can provide new insights into the nature of religious faith and resolve some puzzles, such as how faith can be a virtue.

Published: October 2020

AbstractPurpose of ReviewThis systematic review aimed to determine the effects of interdisciplinary/multidisciplinary outpatient rehabilitation programmes by looking at physical, psychosocial and return to work status of adult cancer patients.Recent FindingsThere is growing evidence that emphasizes the importance of interdisciplinary/multidisciplinary rehabilitation especially in outpatient care, which addresses the complex and individual needs of cancer patients. Many studies focus on measuring the effect of individual rehabilitation interventions.SummaryRandomized controlled trials (RCTs) and before-after studies examining the effects of interdisciplinary/multidisciplinary outpatient rehabilitation programmes were included in this systematic review. The electronic literature search was conducted in MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials and PEDro. The PICO statement was used for selection of the studies. Six randomized controlled trials and six before-after studies were included. Interdisciplinary/multidisciplinary outpatient cancer rehabilitation programmes improved physical and/or psychosocial status of cancer patients. However, non-significant changes in a variety of single physical and psychosocial measures were also common.The findings of the systematic review indicate that interdisciplinary/multidisciplinary outpatient cancer rehabilitation can improve cancer patients’ physical and psychosocial status. This review is limited by the narrative approach due to the heterogeneity of outcome measures. To evaluate effects of rehabilitation, better comparable studies are necessary. Further research is needed in regard to long-term outcomes, effects on return to work status and on the associations depending on cancer type.
How digitalization affects insurance companies: overview and use cases of digital technologies
Authors: Eckert Christian , Osterrieder Katrin 
Published: October 2020

AbstractThe digital transformation is of increasing relevance for insurance companies’ business models. It leads to opportunities as well as challenges, especially for IT departments as core enablers or preventers. Against this background, the aim of this paper is to provide a comprehensive overview of digital technologies (e.g., artificial intelligence, cloud computing) and the resulting use cases for the insurance industry. To this end, we conduct a review of academic articles, industry studies and publications of the supervisory authorities. We point to the resulting requirements for an insurer’s IT and find many interdependencies between the digital technologies. Our results therefore emphasize the importance of a holistic digital strategy.
The strong emergence of molecular structure
Authors: Seifert Vanessa A. 
Published: October 2020

AbstractOne of the most plausible and widely discussed examples of strong emergence is molecular structure. The only detailed account of it, which has been very influential, is due to Robin Hendry and is formulated in terms of downward causation. This paper explains Hendry’s account of the strong emergence of molecular structure and argues that it is coherent only if one assumes a diachronic reflexive notion of downward causation. However, in the context of this notion of downward causation, the strong emergence of molecular structure faces three challenges that have not been met and which have so far remained unnoticed. First, the putative empirical evidence presented for the strong emergence of molecular structure equally undermines supervenience, which is one of the main tenets of strong emergence. Secondly, it is ambiguous how the assumption of determinate nuclear positions is invoked for the support of strong emergence, as the role of this assumption in Hendry’s argument can be interpreted in more than one way. Lastly, there are understandings of causation which render the postulation of a downward causal relation between a molecule’s structure and its quantum mechanical entities, untenable.
Urban water and food security in this century and beyond: Resource-smart cities and residents
Authors: Drangert Jan-Olof 
Published: October 2020

AbstractThe urban world population will increase from 3 to 8.5 thousand million in the 21st century. Cities become hot spots of both demand for water and global food and for disposed used water and nutrients. Sustainability requires that resource flows through our cities are co-managed and connected to agriculture. Reduced use of harmful chemicals in consumer products facilitates treatment to a quality that allows reuse/recycling of water and nutrients. A solid and liquid waste hierarchy can assist in ordering measures. A novel flexible water balance can guide city infrastructure and keep toilet water separate. New water-saving equipment can substantially reduce water use without losing personal comfort. The combination of these new approaches ascertains access to safe urban water, and that recovered nutrients from cities can substitute half of chemical fertilisers needed in food production. Now, thousands of new cities and suburbs provide unique opportunities to develop resource-smart and sustainable flows.
Sporopollenin as a dilution agent in artificial diets for solitary bees
Authors: Tainsh Fiona , Woodmansey Shannon R. , Austin Alexander J. , Bagnall Toby E. , Gilbert James D. J. 
Published: October 2020

AbstractNutritional studies often require precise control of nutrients via dilution of artificial diets with indigestible material, but such studies in bees are limited. Common diluents like cellulose typically result in total mortality of bee larvae, making quantitative studies difficult. We investigated potential alternative dietary dilution agents, sporopollenin (pollen exines) and agar. We rearedOsmia bicornislarvae on pollen diluted with these substances, alongside undiluted controls. Sporopollenin neither prevented nor improved survival, suggesting it is a suitable diluent. Agar appeared marginally to increase survival and its suitability requires further research. Both substances reduced cocoon weight, and sporopollenin also prolonged development, suggesting processing costs. Determining the physiological mechanisms driving these responses requires further work. Our findings should facilitate studies involving nutritional manipulations for solitary bees.

Digitization of neuropsychological diagnostics: a pilot study to compare three paper-based and digitized cognitive assessments
Authors: Latendorf Antje , Runde Lina Marie , Salminen Tiina , Steinert Anika 
Published: October 2020

Abstract
Background and objective
The number of people suffering from dementia is increasing worldwide and so is the need for reliable and economical diagnostic instruments. Therefore, the aim of this study was to compare the processing times of the neuropsychological tests Trail Making Tests A and B (TMT-A/B) and Color-Word Interference Test (CWIT), which were performed in both digital and paper versions.

Methods
The pilot study was conducted among 50 healthy participants (age 65–83 years) using a randomized crossover design. The correlations and differences in the individual processing times of the two test versions were statistically analyzed. Further research questions concerned the influence of the individual usage of technology and the technology commitment of participants as well as the influence of the assessed usability on participants’ performance.

Results
Between the two versions (paper-based vs. digital) statistically significant correlations were found in all tests, e.g., TMT-A r(48) = 0.63, p < 0.01; TMT-B rs(48) = 0.77, p < 0.001). The mean value comparison showed statistically significant differences, e.g., interference table (CWIT) t(49) = 11.24, p < 0.01). Correlations with medium effect were found between the differences in processing times and the individual usage of computer (e.g., rs(48) = − 0.31) and smartphone (rs(48) =  − 0.29) and between the processing times of the TMT-B and the usability (rs(48) = 0.29).

Conclusions
The high correlations between the test procedures appear promising. However, the differences found in the processing times of the two test versions require validation and standardization of digitized test procedures before they can be used in practice.

Published: October 2020

Abstract
Background
Management of elderly patients with acute myocardial infarction (AMI) is challenging due to lack of knowledge about the link between fragility, outcomes and interventional procedures.

Aims
The aim of this study was to establish the prognostic role of the Multidimensional Prognostic Index (MPI) in elderly with AMI.

Methods
A total of 241 patients ≥ 65 years old with AMI were continuously enrolled in this prospective study and divided into three groups according to the MPI score. The primary endpoint was 30-day mortality. Secondary endpoints were 6-month mortality and rate of adverse events.

Results
In-hospital overall mortality rate was higher in MPI-3 (p = 0.009). Patients of MPI-3 had a significantly higher mortality rate regarding the primary endpoint with 30-day survival of 78.9%, compared to 97.4% and 97.2%, in MPI-1, MPI-2 (p < 0.001), respectively. The survival rate progressively decreased in the three MPI classes of risk with a 6-month survival of 96.5%, 96.3%, 73.7% in groups MPI-1, MPI-2, and MPI-3 (p < 0.001). Longer length of in-hospital stay was observed in MPI-3 group. In-hospital complications were more frequent in higher MPI score.

Discussion
Our findings are in agreement with the results of other studies that evaluated the risk of in-hospital complications and mortality in older patients. In our “real-world” population of elderly hospitalized for AMI we observed poorer outcomes in patients belonged to higher MPI groups.

Conclusions
In the setting of AMI, MPI may be very useful in the daily clinical practice to manage older patients and predict the risk of in-hospital and follow-up complications.
Nutrition Transition and Climate Risks in Nigeria: Moving Towards Food Systems Policy Coherence
Authors: Morgan Alexandra E. , Fanzo Jessica 
Published: October 2020

AbstractPurpose of ReviewThe purpose of this review is to describe the combined impacts of the nutrition transition and climate change in Nigeria and analyze the country’s national food-related policy options that could support human and planetary health outcomes.Recent FindingsThis paper uses a food systems framework to analyze how the nutrition transition and climate change interact in Nigeria affecting both diets and the double burden of malnutrition, resulting in what has been termed the syndemic. Interactions between climate change and the nutrition transition in Nigeria are exacerbating diet-related inequities and will continue to do so if food systems continue on their current trajectory and without significant transformation. Siloed policy actions that attempt to mitigate one aspect of food system risk can create a negative feedback loop in another aspect of the food system. Our analysis finds that Nigeria has five national policies that include actionable steps to address food system insufficiencies; however, each of these policies is constrained by the boundaries of singular nutrition, climate change, and agricultural objectives. The country should consider a coherent policy environment that explicitly identifies and links underlying systemic and institutional drivers between climate change and malnutrition that simultaneously and comprehensively address both human and planetary health outcomes of food systems.SummaryThe systemic and institutional outcomes of this emerging syndemic—undernutrition, obesity, and climate change—are inexorably linked. Nigeria lacks a coherent policy environment taking on this challenging syndemic landscape. The analysis in this paper highlights the need for Nigeria to prioritize their national nutrition and agricultural and climate policies that uncouple feedback loops within food systems to address climate change and malnutrition in all its forms.
Quarantined, Sequestered, Closed: Theorising Academic Bodies Under Covid-19 Lockdown
Authors: Gourlay Lesley 
Published: October 2020

AbstractThe term ‘quarantine’ is derived from the Italian quarantena, from quaranta, referring to the forty days of isolation traditionally imposed during the era of the Black Death in Europe. This paper examines this and related contemporary terms, in order to consider the complex and contradictory nature of enforced sites of isolation, with reference to the historical literature. The centrality of spatial practices in the current pandemic is emphasised, with a focus on the normally unobserved, micro practices of individuals under ‘lockdown’. The paper reports on an interview study conducted at a large UK Higher Education institution during the Covid-19 ‘lockdown’, and analyses the accounts of six academics, focusing particularly on their embodied and sociomaterial practices, with reference to the etymological analysis. The paper considers the extent to which their reported experiences reflect the various meanings of the term sequestrato, going on to propose that their working practices, particularly focused on screens and video calls, are characterised by a need to ‘perform the university’. I speculate on how the ontological nature of the university itself has been fundamentally altered by the closure of the campus and lockdown, proposing that the site of the university is now radically dispersed across these sequestered bodies. I conclude by calling into the question the accuracy of the term ‘online teaching and learning’, instead suggesting that in a fundamental sense, none of these practices is in fact ‘online’ or digital.
