Life cycle assessment of aquaculture bivalve shellfish production — a critical review of methodological trends
Authors: Vélez-Henao Johan Andrés , Weinland Franz , Reintjes Norbert 
Published: September 2021

Abstract
Purpose
The increase of shellfish production has raised environmental concerns, i.e., enrichment and redistribution of nutrients and energy consumption. Efforts assessing the environmental burdens arising from the expansion of shellfish production have been made using the life cycle assessment (LCA) methodology. Although LCA has been extensively applied and reviewed in aquaculture systems, shellfish production remains scarcely studied. The objective of this review is to identify methodological trends, highlight gaps and limitations, and provide guidelines for future studies.

Methods
A systematic literature review was applied to scientific studies published up to 2021. A total of 13 documents were shorted by abstract and full text-screening. Literature meeting the inclusion criteria were further analyzed in six different aspects of a LCA (functional unit, system boundaries, data and data quality, allocation, impact assessment methods, interpretation methods). Discussion and guidelines are provided for each reviewed aspect.

Results and discussions
Shellfish LCAs differ considerably from other aquaculture studies mainly because shellfish avoids the allocation of impacts derived from the production of fishmeal. Co-products are present when the shellfish is processed, e.g., in canned products. Furthermore, shellfish studies do not take into account the positive credits from the removal of nutrients from the ecosystems and from the valorization of the shellfish waste (shell and organic remains). Limited information was found for countries outside Europe and species different from mussels. Despite the variability on goals and scopes of the studies, methodological trends were found. The local impacts of the shellfish with the farming area and the impacts on biodiversity have not been included into the studies.

Conclusions and recommendations
Effort should be made in providing the data associated with the fore-background system within the studies in order to improve transparency and to allow the reproduction of the results. Information regarding the natural condition of the cultivation area should be provided as the shellfish production depends mainly on non-anthropogenic conditions. Application of biodiversity assessment methodologies should be encouraged, despite their limitations.

Published: September 2021

ZusammenfassungBildungs- und erziehungswissenschaftliche Fragestellungen, die sich z. B. mit dem Umgang mit (Leistungs‑)Heterogenität von Schüler*innen im Klassenzimmer befassen, sind nicht nur aus der Perspektive des pädagogischen Professionswissens relevant, sondern auch Bestandteil von Diskursen zwischen Wissenschaft, Politik, Gesellschaft und pädagogischer Praxis. Da (angehende) Lehrpersonen als aktiv Beteiligte sowohl produktiv als auch rezeptiv an diesen Diskursen partizipieren, benötigen sie die generische Fähigkeit, Aussagen aus verschiedenen Informationsquellen sowie deren Bedeutsamkeit adäquat einschätzen zu können. Basierend auf dem Multiple-Document-Comprehension-Modell (MDC-Modell) wird in dieser Studie untersucht, ob Lehramtsstudent*innen des Bachelorstudiums (n = 193) an der Paris Lodron Universität Salzburg die aus dem MDC-Modell abgeleiteten kognitiven Anforderungen im Vergleich von Texten beherrschen. Den Student*innen wurde dazu ein wissenschaftlicher Text und ein journalistischer Kommentar zu der Frage des Umgangs mit (Leistungs‑)Heterogenität vorgelegt, auf deren Basis Verifikationsitems bearbeitet werden mussten. Anschließend wurden mithilfe eines kognitiven Diagnosemodells (CDM) die kognitiven Anforderungen des MDC-Modells modelliert, um dessen Mehrdimensionalität empirisch abzubilden. Die Ergebnisse zeigen, dass ca. 93 % der Lehramtsstudent*innen zumindest einen der vier Anforderungsbereiche des MDC-Modells nicht beherrschen. Der Beitrag zeigt somit neue Möglichkeiten in der Diagnostik von Fertigkeiten zum Vergleich multipler Dokumente gemäß des MDC-Ansatzes im Bereich der Lehrer*innenbildungsforschung auf, welche zukünftig auch für die Ausbildung von angehenden Lehrpersonen genutzt werden können.
Primary Soil Contaminants and Their Risks, and Their Relationship to Myocardial Infarction Susceptibility in Urban Krakow (Poland)
Authors: Ciarkowska Krystyna , Konduracka Ewa , Gambus Florian 
Published: September 2021

AbstractWe recorded the concentrations, distributions and sources of 16 polycyclic aromatic hydrocarbons (PAHs), along with zinc (Zn), lead (Pb) and cadmium (Cd), in soils from different areas of Krakow––the city-centre, industrial and residential zones––and from outside the city. Their relationships to the soil properties were examined, and associations were established between the soil pollution in the different areas and myocardial infarction (MI) incidences in 5054 hospitalised patients who had lived in Krakow for more than 30 years. The PAH and Cd concentrations exceeded threshold-effect levels in the city-centre and industrial zones, while Zn, Pb and phenanthrene exceeded probable-effect levels. Industrial incineration processes, coal combustion and petrol-powered vehicles are the main sources of the PAHs, Zn and Cd, while the Pb originates mainly from historical accumulation and the use of Pb-enriched petrol. The mean number of MI incidences in Krakow equated to 0.72% of the residents, while in the city-centre and industrial zones it was ~ 2.8 and 1.2%, respectively. In the residential zone, the mean number of MI incidences was < 0.5% of the residents. These results may suggest that differences in MI incidence in Krakow residents is, at least in part, linked to chronic PAH and heavy-metal exposure.
A quick GRASP-based method for influence maximization in social networks

Published: September 2021

AbstractThe evolution and spread of social networks have attracted the interest of the scientific community in the last few years. Specifically, several new interesting problems, which are hard to solve, have arisen in the context of viral marketing, disease analysis, and influence analysis, among others. Companies and researchers try to find the elements that maximize profit, stop pandemics, etc. This family of problems is collected under the term Social Network Influence Maximization problem (SNIMP), whose goal is to find the most influential users (commonly known as seeds) in a social network, simulating an influence diffusion model. SNIMP is known to be an$$\mathcal {NP}$$NP-hard problem and, therefore, an exact algorithm is not suitable for solving it optimally in reasonable computing time. The main drawback of this optimization problem lies on the computational effort required to evaluate a solution. Since each node is infected with a certain probability, the objective function value must be calculated through a Monte Carlo simulation, resulting in a computationally complex process. The current proposal tries to overcome this limitation by considering a metaheuristic algorithm based on the Greedy Randomized Adaptive Search Procedure (GRASP) framework to design a quick solution procedure for the SNIMP. Our method consists of two distinct stages: construction and local search. The former is based on static features of the network, which notably increases its efficiency since it does not require to perform any simulation during construction. The latter involves a local search based on an intelligent neighborhood exploration strategy to find the most influential users based on swap moves, also aiming for an efficient processing. Experiments performed on 7 well-known social network datasets with 5 different seed set sizes confirm that the proposed algorithm is able to provide competitive results in terms of quality and computing time when comparing it with the best algorithms found in the state of the art.
What’s inside is all that counts? The contours of everyday thinking about self-control
Authors: Bermúdez Juan Pablo , Murray Samuel , Chartrand Louis , Barbosa Sergio 
Published: September 2021

AbstractDoes self-control require willpower? The question cuts to the heart of a debate about whether self-control is identical with some psychological process internal to the agents or not. Noticeably absent from these debates is systematic evidence about the folk-psychological category of self-control. Here, we present the results of two behavioral studies (N = 296) that indicate the structure of everyday use of the concept. In Study 1, participants rated the degree to which different strategies to respond to motivational conflict exemplify self-control. Participants distinguished between intra-psychic and externally-scaffolded strategies and judged that the former exemplified self-control more than the latter. In Study 2, participants provided various solutions to manage motivational conflict and rated their proposals on effectiveness. Participants produced substantially more intra-psychic strategies, rated them as more effective, and advised them at a higher rate than externally-scaffolded strategies. Taken together, these results suggest that while people recognize a plurality of strategies as genuine instances of self-control, purely internal exercises of self-control are considered more prototypical than their externally-scaffolded counterparts. This implies a hierarchical structure for the folk psychological category of self-control. The concept encompasses a variety of regulatory strategies and organizes these strategies along a hierarchical continuum, with purely intra-psychic strategies at the center and scaffolded strategies in the periphery.
Testing, Training, and Optimising Performance of Track Cyclists: A Systematic Mapping Review
Authors: Stadnyk Antony M. J. , Impellizzeri Franco M. , Stanley Jamie , Menaspà Paolo , Slattery Katie M. 
Published: September 2021

Abstract
Background
Track cyclists must develop mental, physical, tactical and technical capabilities to achieve success at an elite level. Given the importance of these components in determining performance, it is of interest to understand the volume of evidence to support implementation in practice by coaches, practitioners, and athletes.

Objective
The aim of this study was to conduct a systematic mapping review to describe the current scale and density of research for testing, training and optimising performance in track cycling.

Methods
All publications involving track cyclist participants were reviewed from four databases (PubMed, SPORTDiscus, Academic Search Complete, Cochrane Library) plus additional sources. Search results returned 4019 records, of which 71 met the inclusion criteria for the review.

Results
The review revealed most published track cycling research investigated athlete testing followed by performance optimisation, with training being the least addressed domain. Research on the physical components of track cycling has been published far more frequently than for tactical or technical components, and only one study was published on the mental components of track cycling. No true experimental research using track cyclists has been published, with 51 non-experimental and 20 quasi-experimental study designs.

Conclusions
Research in track cycling has been growing steadily. However, it is evident there is a clear preference toward understanding the physical—rather than mental, tactical, or technical—demands of track cycling. Future research should investigate how this aligns with coach, practitioner, and athlete needs for achieving track cycling success.

Registration
This systematic mapping review was registered on the Open Science Framework (osf.io/wt7eq).

Authors: Fedeli U. , Schievano E. , Masotto S. , Bonora E. , Zoppini G. 
Published: September 2021

Abstract
Purpose
Diabetes is a growing health problem. The aim of this study was to capture time trends in mortality associated with diabetes.

Methods
The mortality database of the Veneto region (Italy) includes both the underlying causes of death, and all the diseases mentioned in the death certificate. The annual percent change (APC) in age-standardized rates from 2008 to 2017 was computed by the Joinpoint Regression Program.

Results
Overall 453,972 deaths (56,074 with mention of diabetes) were observed among subjects aged ≥ 40 years. Mortality rates declined for diabetes as the underlying cause of death and from diabetes-related circulatory diseases. The latter declined especially in females − 4.4 (CI 95% − 5.3/− 3.4), while in males the APC was − 2.8 (CI 95% − 4.0/− 1.6).

Conclusion
We observed a significant reduction in mortality during the period 2008–2017 in diabetes either as underlying cause of death or when all mentions of diabetes in the death certificate were considered.
Psychosoziale Arbeitsbedingungen und Burnout im Längsschnitt der „Studie zur mentalen Gesundheit bei der Arbeit (S-MGA)“
Authors: Kersten Norbert , Formazin Maren 
Published: September 2021

Zusammenfassung
Hintergrund
Die Gefährdungsbeurteilung psychischer Belastung bei der Arbeit kann als Instrument nur wirksam werden, wenn zum einen die Prädiktoren gesundheitlicher Zielgrößen bekannt sind und zum anderen belegt ist, dass bei einer Änderung der Arbeitsbedingungen hin zu einer günstigen Ausprägung diese gesundheitlichen Zielgrößen zum Positiven veränderbar sind.

Fragestellung
Am Beispiel des Burnout wird in einer Längsschnittanalyse untersucht, ob Änderungen der Arbeitsbedingungen mit entsprechenden Änderungen in der Ausprägung von Burnout einhergehen.

Material und Methoden
In der „Studie zur mentalen Gesundheit bei der Arbeit (S-MGA)“ wurden die psychosozialen Arbeitsbedingungen mit dem Copenhagen Psychosocial Questionnaire (COPSOQ), Burnout mit dem Oldenburger Burnout-Inventar (OLBI) erfasst. Die Daten der Erwerbstätigen beider Erhebungswellen (n = 2005) wurden zu einem Längsschnittdatensatz zusammengefügt. Um den Einfluss der Änderung der COPSOQ-Skalenwerte im Fünf-Jahres-Beobachtungszeitraum auf den Burnout-Score zu ermitteln, wurden Regressionsmodelle mit COPSOQ-Differenzvariablen und den COPSOQ-Ausgangswerten unter Berücksichtigung von möglichen Confoundern angepasst.

Ergebnisse
Die Analyse zeigt, dass der Burnout-Score über einen Zeitraum von 5 Jahren sowohl vom Ausgangsniveau der Anforderungen und Ressourcen als auch von deren Veränderungen abhängt, d. h. sinkende Werte bei den Anforderungen und steigende Werte bei den Ressourcen führen zu sinkenden Burnout-Scores. Die stärksten Effekte in allen Modellen, auch bei gegenseitiger Adjustierung der COPSOQ-Skalen, weist die Arbeitsmenge auf. Ebenso weist die Arbeitsplatzunsicherheit stets signifikante Effekte auf. Anders ist dies bei den Ressourcen, die einzeln im Modell jeweils signifikant sind, bei gegenseitiger Adjustierung der COPSOQ-Skalen jedoch im Effekt nachlassen und teilweise ihre Signifikanz verlieren. Eine Ursache dafür sind die hohen paarweisen Korrelationen der Ressourcen.

Diskussion
Die Analyse zeigt, dass der Burnout-Score im Fünf-Jahres-Längsschnitt sowohl von den Ausgangswerten der Anforderungen und Ressourcen als auch deren Änderungen abhängig ist, also sinkende Anforderungen und steigende Ressourcen zu einem verringerten Burnout-Score führen. Folglich sollten Arbeitsgestaltungsmaßnahmen, die an diesen Arbeitsbedingungen ansetzen, zu einer Verringerung von Burnout beitragen.
Seaweed ingress of cooling water intakes with predictions for Torness power station
Authors: Spanakis Nikolaos , Stansby Peter K. , Rogers Benedict D. , Bernardara Pietro 
Published: September 2021

AbstractSeaweed ingress into the cooling water intakes of nuclear power stations has caused several disruptions to electricity supply. Seaweed is transported by tidal and wave-induced currents after dislodgement from the sea bed following stormy conditions but ingress will be shown to be not only determined by wave conditions. An integrated model system has been developed to predict such ingress and applied at the Torness power station in Scotland where the mass of seaweed recovered was measured for some ingress cases. Prior to each case, seaweed is assumed initially to be distributed in areas surveyed within the surrounding coastal domain with a mass per unit area based on local measurements. Criteria for dislodgement are based on near-bed velocity. Six cases where the mass of ingress was measured and two cases with no ingress have been modelled and predicted by adjusting a dislodgement factor (a multiplier on the threshold velocity) within a relatively narrow range.
Two-Step Optimization of Urban Rail Transit Marshalling and Real-Time Station Control at a Comprehensive Transportation Hub

Published: September 2021

AbstractUrban rail transit connecting with a comprehensive transportation hub should meet passenger demands not only within the urban area, but also from outer areas through high-speed railways or planes, which leads to different characteristics of passenger demands. This paper discusses two strategies to deal with these complex passenger demands from two aspects: transit train formation and real-time holding control. First, we establish a model to optimize the multi-marshalling problem by minimizing the trains’ vacant capacities to cope with the fluctuation of demand in different periods. Then, we establish another model to control the multi-marshalling trains in real time to minimize the passengers’ total waiting time. A genetic algorithm (GA) is designed to solve the integrated two-step model of optimizing the number, timetable and real-time holding control of the multi-marshalling trains. The numerical results show that the combined two-step model of multi-marshalling operation and holding control at stations can better deal with the demand fluctuation of urban rail transit connecting with the comprehensive transportation hub. This method can efficiently reduce the number of passengers detained at the hub station as well as the waiting time without increasing the passengers’ on-train time even with highly fluctuating passenger flow.

Published: September 2021

AbstractOrganic, ionic soil stabilizers (OISS) are designed to regulate directly the hydration properties of clay minerals to improve their engineering behavior. The steps involved in this regulation by OISS are unclear and this might limit their application in the current construction environment in China. The purpose of the present study was to reveal the origin of changes in hydration properties of four typical clay samples (with clay mineral contents of >90 wt.%: Na-bentonite, Ca-bentonite, illite, and kaolinite) as affected by OISS. The water-retention capacity of each clay was measured first through liquid limit and water-vapor adsorption tests. Then, the changes in hydration sites, such as exchangeable cations and the surfaces of minerals, were investigated by a series of microscopic measuring and testing techniques. Finally, infrared spectroscopy (IR) and thermal analysis were performed to verify the regulation of hydration properties by OISS. The results suggested that the exchangeable cation and surface changes controlled the regulation of hydration properties. OISS could cause some of the exchangeable cations to become free ions and disrupt the interaction between some cations and water molecules by its long organic chains; thus, the amount of hydrated cations decreased. In addition, the long organic chains covered the mineral surface and weakened its adsorption capacity. Furthermore, the long chains had cementitious qualities, connecting them to the crystalline layer and resulting in more aggregated clay particles and a smaller specific surface area (SSA). With the decrease in the number of cations and in the SSA by OISS, the hydration of the four clay samples decreased, especially in the case of bentonite.
A Comparison of the Adsorption of Cesium on Zeolite Minerals vs Vermiculite

Published: September 2021

AbstractRadiocesium was deposited on the soils of Fukushima Prefecture in Japan after the meltdown of the Fukushima Daiichi Nuclear Power Plant in 2011. The radiocesium bound to 2:1 clay minerals, such as vermiculite, common in the soil of that region and became non-exchangeable due to the strong affinity of these clay minerals for the Cs+ adsorbed. The current study generated adsorption envelopes for Cs+ on three zeolite minerals: zeolite Y, ZSM-5, and ferrierite. Two of these (ZSM-5 and ferrierite) caused monovalent cations to adsorb via a strong inner-sphere mechanism. A comparison of Cs+ adsorption on these zeolites to Na+ adsorption on the same zeolites showed that Cs+ adsorbs much more strongly than Na+, which is explained by its atomic properties. Despite the inner-sphere adsorption of Cs+ on ZSM-5 and ferrierite, the affinity of vermiculite for Cs+ is even stronger. An adsorption envelope for Cs+ on vermiculite failed to show a low-pH adsorption edge even at a pH of 1.01, with adsorption remaining at ~65% of the maximum even at this low pH. The adsorption envelopes for Cs+ on ZSM-5 and ferrierite minerals did show low-pH adsorption edges centered at pH 3.5 and 3.0, respectively, where Cs+ adsorption dropped to zero. The greater affinity of vermiculite for Cs+, even when compared with that for two zeolite minerals known to have significant affinities for monovalent ions, highlights the difficulty in removing Cs+ from contaminated Fukushima soils.

Abstract
Proximity labeling catalyzed by promiscuous enzymes, such as APEX2, has emerged as a powerful approach to characterize multiprotein complexes and protein–protein interactions. However, current methods depend on the expression of exogenous fusion proteins and cannot be applied to identify proteins surrounding post-translationally modified proteins. To address this limitation, we developed a new method to label proximal proteins of interest by antibody-mediated protein A-ascorbate peroxidase 2 (pA-APEX2) labeling (AMAPEX). In this method, a modified protein is bound in situ by a specific antibody, which then tethers a pA-APEX2 fusion protein. Activation of APEX2 labels the nearby proteins with biotin; the biotinylated proteins are then purified using streptavidin beads and identified by mass spectrometry. We demonstrated the utility of this approach by profiling the proximal proteins of histone modifications including H3K27me3, H3K9me3, H3K4me3, H4K5ac, and H4K12ac, as well as verifying the co-localization of these identified proteins with bait proteins by published ChIP-seq analysis and nucleosome immunoprecipitation. Overall, AMAPEX is an efficient method to identify proteins that are proximal to modified histones.
