Impact for whom? Mapping the users of public research with lexicon-based text mining
Authors: Bonaccorsi Andrea , Chiarello Filippo , Fantoni Gualtiero 
Published: December 2020

AbstractWe contribute to the debate on societal impact of SSH by developing a methodology that allows a fine-grained observation of social groups that make use, directly or indirectly, of the results of research. We develop a lexicon of users with 76,857 entries, which saturates the semantic field of social groups of users and allows normalization. We use the lexicon in order to filter text structures in the 6637 impact case studies collected under the Research Excellence Framework in the UK. We then follow the steps recommended by Börner et al. (Annu Rev Inf Sci Technol 37:179–255, 2003) to build up visual maps of science, using co-occurrence of words describing users of research. We explore the properties of this novel kind of maps, in which science is seen from the perspective of research users.

Published: December 2020

AbstractCollaborations between researchers and practitioners have recently become increasingly popular in education, and educational design research (EDR) may benefit greatly from investigating such partnerships. One important domain in which EDR on collaborations between researchers and practitioners can be applied is research on simulation-based learning. However, frameworks describing both research and design processes in research programs on simulation-based learning are currently lacking. The framework proposed in this paper addresses this research gap. It is derived from theory and delineates levels, phases, activities, roles, and products of research programs to develop simulations as complex scientific artifacts for research purposes. This dual-level framework applies to research programs with a research committee and multiple subordinate research projects. The proposed framework is illustrated by examples from the actual research and design process of an interdisciplinary research program investigating the facilitation of diagnostic competences through instructional support in simulations. On a theoretical level, the framework contributes primarily to the literature of EDR by offering a unique dual-level perspective. Moreover, on a practical level, the framework may help by providing recommendations to guide the research and design process in research programs.

Abstract
Purpose
The success of bariatric surgery varies largely, which may relate to variance in adopting a physically active lifestyle. This study aimed to determine whether two-year changes in physical activity (PA) were associated with weight loss, fat-free mass, cardiorespiratory fitness and quality of life up to two years after bariatric surgery.

Materials and Methods
In this retrospective study, 3879 post-bariatric patients were divided into three groups: 1) decreased PA (n = 388), 2) maintained PA (n = 2002) or 3) increased PA (n = 1498). Measurements regarding PA (Baecke questionnaire), body composition (bioelectrical impedance analysis), estimated cardiorespiratory fitness (Åstrand test) and health-related quality of life (RAND-36) were performed preoperatively and two years post-surgery.

Results
Bariatric patients with increased PA had greater excess weight loss (76.3% vs. 73.2% vs. 72.9%, P < 0.001), greater increases in %fat-free mass (Δ14.0% vs. 13.0% vs. 12.8%; P < 0.001), larger improvements in VO2max (Δ11.8 vs. 10.2 vs. 8.0 ml/kg/min, P < 0.001), and larger increases in health related quality of life subscale scores (P < 0.05) compared to patients with maintained- and decreased PA.

Conclusions
Bariatric patients who managed to induce improvements in habitual physical activity had better body composition, fitness and quality of life at 2 years post-surgery, compared to patients who maintained or even reduced their PA levels. These findings underscore the importance of perioperative-bariatric care programs to change lifestyle and achieve sustainable improvements in PA levels.
Implementing Feedback Granule Size Control in a Continuous Dry Granulation Line Using Controlled Impeller Speed of the Granulation Unit, Compaction Force and Gap Width

Published: December 2020

Abstract
Purpose
In continuous manufacturing of pharmaceuticals, dry granulation is of interest because of its large throughput capacity and energy efficiency. In order to manufacture solid oral dosage forms continuously, valid control strategies for critical quality attributes should be established. To this date, there are no published control strategies for granule size distribution in continuous dry granulation.

Methods
In-line laser diffraction was used to determine the size of granules in a continuous roll compaction/dry granulation line (QbCon® dry). Different process parameters were evaluated regarding their influences on granule size. The identified critical process parameters were then incorporated into control strategies. The uncontrolled and the controlled processes were compared based on the resulting granule size. In both processes, a process parameter was changed to induce a shift in median particle size and the controller had to counteract this shift.

Results
In principle, all process parameters that affect the median particle size could also be used to control the particle size in a dry granulation process. The sieve impeller speed was found to be well suited to control the median particle size as it reacts fast and can be controlled independently of the throughput or material.

Conclusion
The median particle size in continuous roll compaction can be controlled by adjusting process parameters depending on real-time granule size measurements. The method has to be validated and explored further to identify critical requirements to the material and environmental conditions.

AbstractKůlna Cave is the only site in Moravia, Czech Republic, from which large assemblages of both Magdalenian and Epimagdalenian archaeological materials have been excavated from relatively secure stratified deposits. The site therefore offers the unrivalled opportunity to explore the relationship between these two archaeological phases. In this study, we undertake radiocarbon, stable isotope (carbon, nitrogen and sulphur), and ZooMS analysis of the archaeological faunal assemblage to explore the chronological and environmental context of the Magdalenian and Epimagdalenian deposits. Our results show that the Magdalenian and Epimagdalenian deposits can be understood as discrete units from one another, dating to the Late Glacial between c. 15,630 cal. BP and 14,610 cal. BP, and c. 14,140 cal. BP and 12,680 cal. BP, respectively. Stable isotope results (δ13C, δ15N, δ34S) indicate that Magdalenian and Epimagdalenian activity at Kůlna Cave occurred in very different environmental settings. Magdalenian occupation took place within a nutrient-poor landscape that was experiencing rapid changes to environmental moisture, potentially linked to permafrost thaw. In contrast, Epimagdalenian occupation occurred in a relatively stable, temperate environment composed of a mosaic of woodland and grassland habitats. The potential chronological gap between the two phases, and their associations with very different environmental conditions, calls into question whether the Epimagdalenian should be seen as a local, gradual development of the Magdalenian. It also raises the question of whether the gap in occupation at Kůlna Cave could represent a change in settlement dynamics and/or behavioural adaptations to changing environmental conditions.
The dissipative approach to quantum field theory: conceptual foundations and ontological implications
Authors: Oldofredi Andrea , Öttinger Hans Christian 
Published: December 2020

AbstractMany attempts have been made to provide Quantum Field Theory with conceptually clear and mathematically rigorous foundations; remarkable examples are the Bohmian and the algebraic perspectives respectively. In this essay we introduce the dissipative approach to QFT, a new alternative formulation of the theory explaining the phenomena of particle creation and annihilation starting from nonequilibrium thermodynamics. It is shown that DQFT presents a rigorous mathematical structure, and a clear particle ontology, taking the best from the mentioned perspectives. Finally, after the discussion of its principal implications and consequences, we compare it with the main Bohmian QFTs implementing a particle ontology.
ADDRESSING IMBALANCED INSURANCE DATA THROUGH ZERO-INFLATED POISSON REGRESSION WITH BOOSTING
Authors: Lee Simon C.K. 
Published: December 2020

AbstractA machine learning approach to zero-inflated Poisson (ZIP) regression is introduced to address common difficulty arising from imbalanced financial data. The suggested ZIP can be interpreted as an adaptive weight adjustment procedure that removes the need for post-modeling re-calibration and results in a substantial enhancement of predictive accuracy. Notwithstanding the increased complexity due to the expanded parameter set, we utilize a cyclic coordinate descent optimization to implement the ZIP regression, with adjustments made to address saddle points. We also study how various approaches alleviate the potential drawbacks of incomplete exposures in insurance applications. The procedure is tested on real-life data. We demonstrate a significant improvement in performance relative to other popular alternatives, which justifies our modeling techniques.
Application of batch system ultraviolet light on the surface of kashar cheese, a kind of pasta-filata cheese: effects on mould inactivation, lipid oxidation, colour, hardness and sensory properties
Authors: Koca Nurcan , Öztürk Müge Urgu 
Published: December 2020

AbstractThis research paper addresses the hypothesis that the application of ultraviolet (UV) light before packaging of pasta-filata cheese has the potential to eliminate or control post-processing contamination whilst maintaining chemical and sensorial quality. The surfaces of kashar cheese were treated at different doses of UV light (0.32–9.63 kJ/m2) in a batch UV cabinet system to determine effects on physicochemical and sensorial quality as well as mould inactivation. Untreated cheese samples were also used for comparison. Kashar cheese was naturally contaminated in a mouldy environment to provide the desired mould numbers before UV treatments. Log reductions of 0.34, 0.69 and 2.49 were achieved in samples treated at doses of 0.32, 0.96 and 1.93 kJ/m2, respectively and the mould count of sample treated at 9.63 kJ/m2 was below the detection limit. We found no significant differences in composition and hardness values between any of the treated or control cheeses. Although some individual colour values increased as the UV doses increased, this change was not observed visually in sensory analysis. Increased light intensity accelerated the lipid oxidation causing a perception of off-flavour. The results of this study show that it is necessary to examine the relationship between the oxidative and sensory interactions while determining the effective doses applied to cheese surface for microbial inactivation.
Attalid aesthetics: the Pergamene ‘baroque’ reconsidered
Authors: Nelson Thomas J. 
Published: December 2020

Abstract:In this paper, I explore the literary aesthetics of Attalid Pergamon, one of the Ptolemies’ fiercest cultural rivals in the Hellenistic period. Traditionally, scholars have reconstructed Pergamene poetry from the city’s grand and monumental sculptural programme, hypothesizing an underlying aesthetic dichotomy between the two kingdoms: Alexandrian ‘refinement’ versus the Pergamene ‘baroque’. In this paper, I critically reassess this view by exploring surviving scraps of Pergamene poetry: an inscribed encomiastic epigram celebrating the Olympic victory of a certain Attalus (IvP I.10) and an inscribed dedicatory epigram featuring a speaking Satyr (SGO I.06/02/05). By examining these poems’ sophisticated engagements with the literary past and contemporary scholarship, I challenge the idea of a simple opposition between the two kingdoms. In reality, the art and literature of both political centres display a similar capacity to embrace both the refined and the baroque. In conclusion, I ask how this analysis affects our interpretation of the broader aesthetic landscape of the Hellenistic era and suggest that the literature of both capitals belongs to a larger system of elite poetry which stretched far and wide across the Hellenistic world.
Towards One-Dollar Robots: An Integrated Design and Fabrication Strategy for Electromechanical Systems
Authors: Yan Wenzhong , Mehta Ankur 
Published: December 2020

SUMMARYTo improve the accessibility of robotics, we propose a design and fabrication strategy to build low-cost electromechanical systems for robotic devices. Our method, based on origami-inspired cut-and-fold and E-textiles techniques, aims at minimizing the resources for robot creation. Specifically, we explore techniques to create robots with the resources restricted to single-layer sheets (e.g., polyester film) and conductive sewing threads. To demonstrate our strategy’s feasibility, these techniques are successfully integrated into an electromechanical oscillator (about 0.40 USD), which can generate electrical oscillation under constant-current power and potentially be used as a simple robot controller in lieu of additional external electronics.

Published: December 2020

AbstractObjective:To describe the duration of breast-feeding between 1990 and 2013 and to estimate the association between breast-feeding duration and sociodemographic, health and pro-breast-feeding policies and programmes in Latin American countries.Design:This is a cross-sectional study with data from Demographic and Health Surveys programme conducted in Bolivia, Brazil, Colombia, Peru and the Dominican Republic between 1990 and 2013. The median duration of breast-feeding was estimated by survival analysis. Information on pro-breast-feeding policies and programmes was extracted from the World on Breastfeeding Trends Initiative (WBTi) tool. The association between the duration of breast-feeding and WBTi tool score was analysed by multilevel survival regression.Setting:Nationally representative cross-sectional survey from Bolivia, Brazil, Colombia, Peru and Dominican Republic.Participants:We included children under 24 months of age, totalling 17 318 children.Results:Breast-feeding duration showed a significant increase in all countries, except the Dominican Republic. Mothers with higher schooling level (HR = 1·66; 95 % CI 1·35, 2·04), higher income (HR = 1·58; 95 % CI 1·40, 1·77) and overweight (HR = 1·14; 95 % CI 1·05, 1·23) breastfed for a shorter time. Breast-feeding in the first hour of life (HR = 0·79; 95 % CI 0·74, 0·83) was associated with increase in the duration of breast-feeding. Regarding WBTi, Peru presented the lowest score and the Dominican Republic presented the highest score. WBTi score was inversely related to the duration of breast-feeding for this set of countries (HR = 1·07; 95 % CI 1·02, 1·12).Conclusions:Mothers with better socio-economic conditions and overweight breastfed for a shorter time. Breast-feeding in the first hour was associated with longer duration of breast-feeding. In this set of countries, higher scores from WBTi tool did not result in longer duration of breast-feeding.
Is it possible to gain energy at work? A questionnaire study in primary health care
Authors: Ejlertsson Lina , Heijbel Bodil , Brorsson Annika , Andersson H. Ingemar 
Published: December 2020

Abstract

Objectives:
The area of regenerative work is still close to unexplored. The aim was to explore the possibility for employees to gain energy at work.

Methods:
Questionnaire to all employees (n = 599) from different professions in public and private primary health care centers in one health care district in Sweden. The questionnaire, which had a salutogenic perspective, included information on self-rated health, psychosocial work environment and experiences, recovery, social climate, and energy. Having an energy-building experience was defined by a positive response to two combined questions regarding energy at work. Analyses were performed with bivariate correlation and multiple logistic regression.

Results:
The response rate was 84%. Health and energy correlated positively (r = 0.54). In total, 44.5% of the employees reported having an energy-building experience. Predictors for having an energy-building experience were recovery [positive odds ratio (POR) = 2.78], autonomy (POR = 2.26), positive workplace characteristics (POR = 2.09), and internal work experiences (POR = 1.88).

Conclusions:
The results support the hypothesis that it is possible to gain energy at work, an area that is still close to unexplored. There is a high correlation between energy and health. Employees’ energy-building experiences relate to well-being at work and correlates to recovery, autonomy, positive workplace characteristics, and positive internal work experiences. This knowledge can help in improving future work environment development.

AbstractAimsHealthcare workers exposed to coronavirus 2019 (COVID-19) patients could be psychologically distressed. This study aims to assess the magnitude of psychological distress and associated factors among hospital staff during the COVID-19 pandemic in a large tertiary hospital located in north-east Italy.MethodsAll healthcare and administrative staff working in the Verona University Hospital (Veneto, Italy) during the COVID-19 pandemic were asked to complete a web-based survey from 21 April to 6 May 2020. Symptoms of post-traumatic distress, anxiety and depression were assessed, respectively, using the Impact of Event Scale (IES-R), the Self-rating Anxiety Scale (SAS) and the Patient Health Questionnaire (PHQ-9). Personal socio-demographic information and job characteristics were also collected, including gender, age, living condition, having pre-existing psychological problems, occupation, length of working experience, hospital unit (ICUs and sub-intensive COVID-19 units vs. non-COVID-19 units). A multivariable logistic regression analysis was performed to identify factors associated with each of the three mental health outcomes.ResultsA total of 2195 healthcare workers (36.9% of the overall hospital staff) participated in the study. Of the participants, 35.7% were nurses, 24.3% other healthcare staff, 16.4% residents, 13.9% physicians and 9.7% administrative staff. Nine per cent of healthcare staff worked in ICUs, 8% in sub-intensive COVID-19 units and 7.6% in other front-line services, while the remaining staff worked in hospital units not directly engaged with COVID-19 patients. Overall, 63.2% of participants reported COVID-related traumatic experiences at work and 53.8% (95% CI 51.0%–56.6%) showed symptoms of post-traumatic distress; moreover, 50.1% (95% CI 47.9%–52.3%) showed symptoms of clinically relevant anxiety and 26.6% (95% CI 24.7%–28.5%) symptoms of at least moderate depression. Multivariable logistic regressions showed that women, nurses, healthcare workers directly engaged with COVID-19 patients and those with pre-existing psychological problems were at increased risk of psychopathological consequences of the pandemic.ConclusionsThe psychological impact of the COVID-19 pandemic on healthcare staff working in a highly burdened geographical of north-east Italy is relevant and to some extent greater than that reported in China. The study provides solid grounds to elaborate and implement interventions pertaining to psychology and occupational health.
The reciprocal jaw-muscle reflexes elicited by anterior- and back-tooth-contacts—a perspective to explain the control of the masticatory muscles
Authors: Vaahtoniemi Lauri 
Published: December 2020

Abstract
Aims
Tooth-contact sensations are considered essential to boost jaw adductor muscles during mastication. However, no previous studies have explained the importance of the inhibitory reflex of human anterior-tooth (ANT)-contacts in mastication. Here I present the “reciprocal reflex-control-hypothesis” of mammalian mastication.

Subjects and setting of the study
I demonstrate the hypothesis with the live kinematics of free jaw-closures as inferred from T-Scan recordings of dental patients.

Results
The jaw-closures started with negligible force, predominantly with ANT-contacts (the AF-bites). The first ANT-contact inhibited the first kinematic tilt of the mandible, whereas the bites starting from a back-tooth (BAT)-contact (the BF-bites) accelerated the first tilt. The second tilt established a low-force static tripod of the ANT- and bilateral BAT-contacts for a fixed mandible-maxilla relation. Thereafter, semi-static bite force increased rapidly, relatively more in the BAT-area.

Discussion and Conclusions
In the vertical-closure phase of chewing, the primate joint-fulcrum (class 3 lever) conflicts with the food-bolus-fulcrum in the BAT-area (class 1 lever). The resilient class 3 and 1 lever systems are superseded by an almost static mechanically more advantageous class 2 lever with a more rigid fulcrum at the most anterior ANT-contact. For humans, the class 2 levered delivery of force also enables forceful horizontal food grinding to be extended widely to the BAT-area.
