Classifying the Diversity of Urban Diversities: an Inductive Analysis of European Cities
Authors: Pisarevskaya Asya , Scholten Peter , Kaşlı Zeynep 
Published: July 2021

AbstractThis paper provides an empirical classification of migration-related diversities in 166 European cities. The local turn in migration studies has shown that migration-related diversity may take varied forms in different cities. Our understanding of how and why cities differ is lagging behind the wealth of existing conceptualisations. This is partly because most studies look only at one kind of city, in particular, superdiverse global cities. This paper takes a systematic inductive approach to map the diversity of migration-related diversities in urban setting and understand the reasons behind such variations. Applying quantitative classification methods to European cities in France, Germany, the Netherlands and Italy, we search for a new meaningful classification of the urban diversity configurations based on measures of volume, variety and spread of migration-related diversity. Five empirical clusters of cities of migration are found: superdiverse cities, migrant minority cities, new diversity cities, low-migration cities and non-diverse cities. Subsequently, we develop a better qualitative understanding of these clusters by examining typical cities, their economic positioning, migration history, their policy and political structures, as well as their social and geographical position. A thorough classification, we argue, is necessary to have a more differentiated view of the existing urban diversities and go beyond one-size-fits-all solutions for urban governance of migration-related diversity.

AbstractThe purpose of this study was to investigate the biological properties of an extract obtained from the waste of blueberry fruit. The study covered the optimization of extraction of antioxidants from blueberry pomace and the determination of antioxidant properties of the extract using HaCaT as the model organism. Research showed that the yield of antioxidants extraction from blueberry waste was dependent on the applied extraction conditions. Based on the mathematical models, the optimal conditions of extraction process in which the maximum quantity of antioxidant compounds is achieved from the waste mass unit, i.e., the relation of the waste mass to the volume of ethanol equal to 1:17.36, and process time equal to 1000 s. The obtained extract was characterized by high antioxidant activity, which was shaped by high content of polyphenols, mainly anthocyanins. Moreover, the extract showed a high ability to protect HaCaT cells from the occurrence of oxidative stress induced by H2O2. Cells treated with the extract and H2O2 generated a lower amount of ROS than cells treated with H2O2 only. The obtained results will be base of further studies on applying the extract in production of diet supplements and functional foods with increased antioxidant activity. Moreover, the main research material is blueberry pomace which is a troublesome waste material for juice producers. Consequently, according to a sustainable development idea, the study results will provide an opportunity to increase interest in the problem of rational use of the waste material to a certain extent.
Habitat Attributes Dictate the Roles of Dispersal and Environmental Filtering on Metacommunity Assembly at Coastal Soft-Bottom Ecosystems
Authors: Brustolin Marco C. , Fonseca Gustavo , Gallucci Fabiane 
Published: July 2021

AbstractTracking the effects of habitat attributes on species distribution is pivotal to the understanding of community assembly across space and time. We used the elements of metacommunity (EMS), which evaluates coherence, turnover, and boundary clumping of species, to access the spatial patterns of nematodes from three coastal habitats with increasing degree to wave exposure, namely, mangroves, estuarine unvegetated tidal flats, and sandy beaches. Each habitat was sampled in four locations, hundreds of kilometers apart from each other. We hypothesized that (1) coastal habitats act as metacommunity boundaries and drive positive turnover and clumped distribution of species and (2) metacommunity structure within coastal habitats depends on the habitats’ degree to wave exposure since wave energy generally decreases sediment heterogeneity and favors connectivity among locations. Habitats were the main drivers of species turnover, with tidal flats harboring a transitional assemblage between mangrove and sandy beach. Metacommunities from the different habitats showed distinct patterns of organization among locations. Mangroves were characterized by species loss, with smaller areas of mangroves harboring a subset of the species pool present on larger areas of mangroves. Tidal flats showed positive species turnover among the different estuaries, with co-occurring species responding as a group to environmental variations. Both patterns indicate environmental filtering as the main driver at these less wave-exposed habitats. At sandy beaches, in contrast, metacommunity displayed a random pattern, suggesting high connectivity among locations. Our study confirmed that habitat attributes may induce distinct mechanisms of metacommunity assembly at coastal soft-bottom ecosystems.
Sexbots as Synthetic Companions: Comparing Attitudes of Official Sex Offenders and Non-Offenders

Published: July 2021

AbstractThis is the first Italian study to examine views on sexbots of adult male sex offenders and non-offenders, and their perceptions of sexbots as sexual partners, and sexbots as a means to prevent sexual violence. In order to explore these aspects 344 adult males were involved in the study. The study carried out two types of comparisons. 100 male sex offenders were compared with 244 male non-offenders. Also, sex offenders were divided into child molesters and rapists. Preliminary findings suggest that sex offenders were less open than non-offenders to sexbots, showed a lower acceptance of them, and were more likely to dismiss the possibility of having an intimate and sexual relationship with a sexbot. Sex offenders were also less likely than non-offenders to believe that the risk of sexual violence against people could be reduced if a sexbot was used in the treatment of sex offenders. No differences were found between child molesters and rapists. Though no definitive conclusion can be drawn about what role sexbots might play in the prevention and treatment of sex offending, this study emphasizes the importance of both exploring how sexbots are both perceived and understood. Sex offenders in this study showed a high dynamic sexual risk and, paradoxically, despite, or because of, their sexual deviance (e.g. deficits in sexual self-regulation), they were more inclined to see sexbots as just machines and were reluctant to imagine them as social agents, i.e. as intimate or sexual arousal partners. How sex offenders differ in their dynamic risk and criminal careers can inform experts about the mechanisms that take place and can challenge their engagement in treatment and intervention.
Biochar, compost and arbuscular mycorrhizal fungi: a tripartite approach to combat Sclerotinia sclerotiorum in soybean

Published: July 2021

AbstractSclerotinia stem rot, caused bySclerotinia sclerotiorum(Lib.) de Bary, is a major disease in soybean in many parts of the world. Sustainable control measures to combat this pathogen can be better achieved by combining different available tools. One element to control fungal diseases could be changing biological activities by adding organic matter inputs, such as biochar and compost, to the soil. Other players are arbuscular mycorrhizal fungi (AMF); bioprotective effects have already been documented for them. In the present study, we assessed the effect of organic matter inputs, such as compost alone at the application rate of 20% of the total substrate (v/v) and/or green waste biochar at the application rate of 3% (v/v) in combination with or without arbuscular mycorrhizal fungi, againstSclerotinia sclerotiorumand their effect on plant growth characteristics in soybean. Substrates including compost resulted in a lower disease severity in both, plants inoculated and non-inoculated with AMF. The AMF root colonization was highest in plants grown in the control treatment and green waste biochar substrate inoculated withSclerotinia sclerotiorum; the lowest colonization was found in plants grown in substrates containing compost. Soil substrates, especially compost, affected shoot dry matter production in soybean plants inoculated withSclerotinia sclerotiorumand in non-inoculated plants; compost alone was superior in treatments with and without AMF. Root morphological traits were more strongly influenced by AMF than by the substrate. Our findings suggest that compost has a positive effect in terms of soybean growth and diseases suppression, which is more pronounced than that of biochar and AMF.

Published: July 2021

AbstractAs a photocatalyst with good prospects, TiO2 has the shortcomings of easy agglomeration and no catalytic performance under visible light. The purpose of the present study was to help solve these problems by employing muscovite as a carrier for N-doped TiO2 in a nanocomposite. The nanocomposites were prepared by a liquid precipitation-grinding method using muscovite as the matrix and urea as the nitrogen source. The crystal structures, chemical bonding, and micromorphology of the nanocomposites were analyzed by X-ray diffraction, infrared absorption spectrometry, and field emission scanning electron microscopy, respectively. Visible and ultraviolet (UV-Vis) light absorption of the nanocomposites was analyzed by solid ultraviolet diffuse reflectance spectroscopy. The photocatalytic effect of the nanocomposites was studied based on the degradation of rhodamine B (RhB) solution. The photocatalytic degradation product of RhB was detected by high-performance liquid chromatography-mass spectrometry, revealing that N-doping inhibits the growth of TiO2 nanoparticles. The photocatalytic performance of N-TiO2/muscovite composite nanomaterials decreased with increasing heat-treatment temperature. N-doped TiO2/muscovite nanocomposites that were heated at 400°C showed the best photocatalytic performance under visible-light illumination with an RhB degradation of 97%.

Published: July 2021

AbstractVarved clay deposits from ice-dammed lakes are a particularly important and broadly applied raw material used for the production of high-quality ceramics (red bricks, roof tiles, etc.), but the mineralogy and geochemistry of these sediments are not fully understood. The aim of the present study was to determine the chemical and mineralogical composition of ice-dammed lake sediments of the Lębork deposit. Major-element analysis of the compositions of selected samples from the ice-dammed lake clays was performed by X-ray fluorescence (XRF) and trace elements were determined by inductively coupled plasma-mass spectrometry. The mineralogical composition of clay samples was determined by X-ray diffraction (XRD). Analyses of the chemical composition of the ice-dammed lake clays of the Lębork deposit showed that the dominant component was SiO2 with a mean content of 56.13 wt.%; the second most abundant component was Al2O3, with a mean content for the entire deposit of 11.61 wt.%. Analysis by ICP-MS indicated the presence of rare earth elements (REE), e.g. cerium, neodymium, lanthanum, and praseodymium; their mean contents are: 56.9, 27.0, 26.3, and 7.3 ppm, respectively. Mineralogical analysis of the varved clays identified quartz, muscovite, calcite, and clay minerals – illite, kaolinite, and montmorillonite. The material filling the Lębork basin is characterized by small lateral and vertical variability in chemical composition. The results of the present study may be of considerable importance in determining the parent igneous, metamorphic, and sedimentary rocks, the weathering products of which supplied material to the ice-dammed lake, as well as in determining the mechanisms and character of the sedimentation process itself.
Kelly and Jackson networks with interchangeable, cooperative servers
Authors: Wang Chia-Li , Wolff Ronald W. 
Published: July 2021

AbstractIn open Kelly and Jackson networks, servers are assigned to individual stations, serving customers only where they are assigned. We investigate the performance of modified networks where servers cooperate. A server who would be idle at the assigned station will serve customers at another station, speeding up service there. We assume interchangeable servers: the service rate of a server at a station depends only on the station, not the server. This gives work conservation, which is used in various ways. We investigate three levels of server cooperation, from full cooperation, where all servers are busy when there is work to do anywhere in the network, to one-way cooperation, where a server assigned to one station may assist a server at another, but not the converse. We obtain the same stability conditions for each level and, in a series of examples, obtain substantial performance improvement with server cooperation, even when stations before modification are moderately loaded.
Markov chain approximation of one-dimensional sticky diffusions
Authors: Meier Christian , Li Lingfei , Zhang Gongqiu 
Published: July 2021

AbstractWe develop a continuous-time Markov chain (CTMC) approximation of one-dimensional diffusions with sticky boundary or interior points. Approximate solutions to the action of the Feynman–Kac operator associated with a sticky diffusion and first passage probabilities are obtained using matrix exponentials. We show how to compute matrix exponentials efficiently and prove that a carefully designed scheme achieves second-order convergence. We also propose a scheme based on CTMC approximation for the simulation of sticky diffusions, for which the Euler scheme may completely fail. The efficiency of our method and its advantages over alternative approaches are illustrated in the context of bond pricing in a sticky short-rate model for a low-interest environment and option pricing under a geometric Brownian motion price model with a sticky interior point.
The Church of England and the Coronation Rite, 1761–1838
Authors: Dixon Nicholas 
Published: July 2021

AbstractBritish coronations from 1761 to 1838 have conventionally been dismissed as tawdry pageants with little religious significance. The study of these ceremonies has also been impeded by the dominance of historiographical frameworks characterizing the later Georgian period as an era of political secularization. Drawing upon many neglected sources, this article challenges such presuppositions by situating the Anglican clergy in the foreground of coronations and exploring the ways in which these events were perceived to retain a religious and political significance. The discussion encompasses theoretical understandings of coronations and the practical tensions between church and state exposed by them.
Progression of asexual to sexual stages of Cystoisospora suis in a host cell-free environment as a model for Coccidia
Authors: Feix Anna Sophia , Cruz-Bustos Teresa , Ruttkowski Bärbel , Mötz Marlene , Rümenapf Till , Joachim Anja 
Published: July 2021

AbstractCoccidia display a characteristic life cycle, where the parasites switch between asexual and sexual development, resulting in an environmental stage, the oocyst. The entero-pathogenic Cystoisospora suis, a coccidian parasite of swine and close relative to Toxoplasma gondii, undergoes development in one host-cycle. Despite the well-described intracellular development of Coccidia, the C. suis life cycle can progress in an in vitro, host cell-free system after initial intracellular development of merozoites. A novel host cell-free cultivation method was developed by transferring purified merozoites from cell culture supernatant (dpi 6) to culture medium and incubating them for 5 days to induce their progression to sexually differentiated stages. The development of sexual stages in the absence of host cells was verified by morphological studies, flow cytometry and the transcription analysis of three genes linked to sexual stages (HAP2, OWP and TyRP). The host cell-free culture permits the sexual development (and with this, the complete life cycle progression from sporozoites to oocysts) of C. suis in vitro and provides a new tool for detailed research on the development of C. suis and possibly other Coccidia. This will also be useful for the evaluation of novel drug or vaccine targets in these parasites.

Published: July 2021

Abstract

Objective
To assess the adherence of economic evaluations to the recommendations on principles of economic evaluation as stated in the country-specific guidelines for three countries across different income groups, namely, Canada, South Africa, and Egypt.

Methods
Searches were undertaken in three databases to identify economic evaluations meeting predefined inclusion criteria. Methodological and reporting standards listed in the country-specific guidelines were converted into discrete binary variables to calculate mean adherence scores. Quality appraisal was done using Drummond's checklist. Stratified analysis was undertaken to identify independent variables affecting adherence.

Results
We identified forty-four, seventy-nine, and sixteen economic evaluations for Canada, South Africa, and Egypt, respectively. The mean adherence score was the highest for Canada (71%), followed by South Africa (65%) and Egypt (60%). Adherence to guidelines was positively correlated with quality of studies, r = .72. Furthermore, the mean adherence score was significantly (p < .05) higher for studies using a cost-utility analysis design (72%), having local/national funding aid (72%), undertaken by a health economist (71%) and for pharmacoeconomic evaluations (70%).

Conclusion
The quality of economic evaluations improves with adherence to country-specific guidelines. Locally funded and health-economist led health technology assessments (HTAs) should be encouraged for greater adherence to the guidelines. The HTA researchers and the HTA bodies should lay emphasis on adherence to the country-specific guidelines for improving the quality of HTA evidence.
Students, Suffrage, and Political Change: The College Equal Suffrage League and Campus Campaigns for Women’s Right to Vote, 1905–1920
Authors: Marino Kelly 
Published: July 2021

AbstractFrom 1905–1920, American college and university students carried on active and understudied campaigns to gain legitimacy and support for women’s suffrage at institutions of higher education across the United States. The primary organization responsible for initiating and directing campus activism was the College Equal Suffrage League (CESL), formed in 1900 by Massachusetts teachers Maud Wood Park and Inez Haynes Gillmore to recruit more upper- and middle-class, well-educated, students and alumni to the women’s rights movement. Exploring the records of state and national suffragists, women’s organizations, and academic institutions associated with the CESL shows that the league’s campaigns helped to reinvigorate the suffrage cause at an important moment in the early twentieth century by using educational tactics as powerful tools to cultivate a scholarly voice for the campaign, appeal to the upper classes, and fit within the contexts of higher education and larger movement for progressive reform. In addition to influencing the suffrage cause, campus organizing for equal voting rights changed the culture of female political activism and higher education by ushering a younger generation of articulate and well-trained activists into the women’s rights campaign and starting in a trend of organized youth mobilization for women’s rights at colleges and universities.
Synthesis and design of filters and multiplexers with acoustic transversal topology

Published: July 2021

AbstractThe novel acoustic transversal topology has demonstrated to be a potential candidate for the development of the next generation of communication filters. The major asset of this topology is its capacity to achieve any filter response without the detriment of limited electro-acoustic coupling. Additionally, this topology prompts for an easy connection of different filters to create multiband and multiplexing responses. This study recalls and further details on the design of multiplexers based on transversal topology using bulk acoustic wave (BAW) or surface acoustic wave (SAW) resonators. An important practical aspect of this topology is the need of a BALUN stage at one port of the filter.The use of the transversal topology is then applied to another type of acoustic resonator configuration, coupled resonator filter (CRF). Such a resonator configuration offers control over the phase of each transversal path, allowing us to eliminate the BALUN stage. CRF resonators are modeled by means of a different circuit model than BAW or SAW, which calls for a new synthesis procedure. This paper describes the synthesis approach and circuit transformation for the development of multiplexers based on the transversal arrangement of the CRF resonators. An example of a fully simulated 9-plexer is provided to verify this procedure.

Published: July 2021

AbstractIn this article a compact circular monopole antenna is represented with dimensions of 38.87 × 24.00 × 1.60 mm3 applicable for WLAN/Wi-MAX and satellite band rejection characteristics. The impedance bandwidth is 9.42 GHz (3.12–12.54 GHz) for the final antenna with an equivalent fractional bandwidth of about 120.31%, producing triple notched bands centered at 3.95, 5.20 and 8.90 GHz with assistance of Archimedean spiral slot and incorporation of defected ground structure allowing WLAN (5.2 GHz), WiMAX (3.5 GHz) and higher satellite X-band (8.5 GHz) filtering abilities. Simulations of the antenna are performed to attain preferable return loss properties as well as gain and omni-directional radiation patterns. The suggested antenna yields a peak gain of about 7.46 dBi at 11.30 GHz and experimental values are in good obedience with simulated ones.
