AbstractA new cost‐effective NHS functionalized polyoxazoline (POx) loaded polymer with strong hemostatic properties has been developed. In this study, we investigate POx loaded hemostatic patches regarding hemostatic efficacy, local inflammatory reaction and wound‐healing, as compared to the non‐POx treated blanks and commercially available hemostatic products. Hundred and ten rats divided into 11 groups of 10 animals underwent partial liver lobe resection. Eight groups received experimental patches, two groups commercially available hemostatic patches (TachoSil® and Veriset™, positive controls), one group with gauzes (negative control). Each animal received twice a patch with a size 1.5 × 2.5 cm, on each partially resected lobe. Primary endpoint was time to hemostasis (TTH). The rats were sacrificed at different time points (1, 3, or 7 days) to measure local inflammatory response and early wound healing. Of the POx loaded patches, GFC NHS‐POx (TTH 20.4 s, p = .019) and GFC‐NHS‐POx1.5 (TTH 0.0 s, p = .003) showed significantly faster TTH compared to TachoSil® (TTH 95.4 s), and were comparable to Veriset™ (TTH 17.0 s). Three patches, GFC‐NHS‐POx 1.5 (TTH 0.0 s, p = .016), ORC NHS‐POx:NU‐POx (TTH 91.4 s, p = .033), and ORC‐PLGA NHS‐POx:NU‐POx (TTH 105.6 s, p = .04) had a lower TTH compared to their own blank carrier (TTH 74.9, 157.8, and 195.7 s, respectively). With regard to biocompatibility, all POx loaded patches showed results comparable to TachoSil® and Veriset™. NHS‐POx‐loaded hemostatic patch demonstrate fast and effective hemostasis, comparable or better than commercially available hemostatic patches, with similar early biocompatibility.
Reflections on philanthropy and organizing in the United States
Authors: Frey Ethan 
Published: September 2021

AbstractPhilanthropic foundations play a major role in supporting community organizing efforts around the country. Even as they provide millions of dollars each year to enable organizing, they have also come under significant criticism for investment approaches that sometimes hinder and even undermine the core goals of organizing itself. This paper focuses on reflections from a funder seeking to support community organizing and the challenges of doing so within the structures of the philanthropic community. In particular the paper examines the way notions of power, theories of change used to justify philanthropic investments, and entrenched assumptions about social change shape the ability of funders to leverage their perch to support organizing. The paper also contextualizes these reflections in a broader debate about the appropriate relationship between funders and grassroots organizing.

Published: September 2021

AbstractBACKGROUNDThe present work investigates the use of municipal mixed waste compost (MMWC) residue for phosphorus (P) recycling from a technical, economic, and environmental perspective. The study aims to obtain liquid extracts rich in P from MMWC with a low heavy metals content, suitable for their subsequent precipitation in the struvite form. The effect of inorganic (sulfuric/nitric) and organic (oxalic/citric) acids at different molarities and temperatures was studied using technical analysis. The preliminary economic analysis allows the costs of the extraction section for the optimal extraction strategies to be estimated and compared.RESULTSBased on the multilevel factorial design, the P extraction optimization shows that sulfuric acid 0.5 M and 30 °C provided the highest P extraction yield, 94.2%. However, oxalic acid 0.1 M and 30 °C is the best choice to maximize the P extraction yield, while also minimizing the heavy metals concentration, reaching a P recovery of 2.5 g P/kg. The extraction kinetics for all tested acids were satisfactorily modelled using a second‐order model (r2 > 0.99). The preliminary economic analysis, estimated for a P extraction pilot plant of 100 kg h−1 of MMWC, noted that sulfuric acid 0.5 M provided the lowest total investment cost (130 000 €) and a minimum sale price of theoretical struvite at 4.96 €/kg.CONCLUSIONMMWC is a promising raw material for P recycling as fertilizer due to an appreciable P concentration (7 g P/kg), which can be used together with other residues rich in P to obtain an economical and sustainable extraction process. © 2021 The Authors.

AbstractThis study aimed to characterize the palynological morphology of melliferous species of family Asteraceae belonged to seven tribes which were categorized into 15 genera and were studied under light and scanning electron microscopy. The pollen grains were acetolyzed, measured, and described qualitatively. Quantitative data were analyzed by descriptive and multivariate statistical analysis. The species were analyzed considering 11 quantitative pollen characteristics. The study revealed that the pollen grains are circular, triangular, angular, semi‐angular, quadrangular, pentagonal and hexagonal amb, and 3‐colporate or 3‐colpate. The size of the pollen is variable among the species, ranged from 56.1 to 23.2 μm. Three pollen types: oblate spheroidal (eight species), prolate spheroidal (six species), and suboblate (two species) were observed. The surface pattern of the exine varies from echinoperforate, echinate, echinate microperforate, fenestrate, echinoperforate reticulate, microreticulate, echinate perforate, tectate, and scabrate. Exine thickness was calculated minimum in Cichorium intybus (2.47 μm) and maximum in Taraxacum campylodes (5.15 μm). A key to studied bee floral species, based on the morphological features of pollen grains, is also provided. The palynomorphological characters here analyzed can be potentially used to correctly identify the Asteraceous honeybee floral species most commonly plants visited by honeybees in the study area.

Published: September 2021

SummaryOur research examined how team age diversity can be either detrimental or beneficial for team performance depending on team agreeableness minimum. In age diverse teams, a disagreeable teammate may trigger age‐based stereotypes about his/her social group, thereby activating social categorization. This would result in decreased relational team functioning and worsened team performance. When the least agreeable member scores high on agreeableness, negative social categorization processes may not be triggered in age diverse teams. They may focus on informational diversity with beneficial effects for team relational processes and team performance. We tested our model in three samples (Study 1: k = 81, N = 254; Study 2: k = 109, N = 434; Study 3: k = 195, N = 1784) wherein performance was measured both objectively (Studies 1 and 2) and subjectively (Study 3). In both Studies 1 and 2, team age diversity was positively related to team performance when team agreeableness minimum was high. In Study 2, when the least agreeable person scored low on agreeableness, greater age diversity resulted in lower performance, and this relationship was mediated by higher interpersonal conflict. In Study 3, these interactive effects transpire via reduced team cohesion—another aspect of relational team functioning.

Published: September 2021

ABSTRACTA submillennial‐resolution record of lake water oxygen isotope composition (δ18O) from chironomid head capsules is presented from Burial Lake, northwest Alaska. The record spans the Last Glacial Maximum (LGM; ~20–16k cal a bp) to the present and shows a series of large lake δ18O shifts (~5‰). Relatively low δ18O values occurred during a period covering the LGM, when the lake was a shallow, closed‐basin pond. Higher values characterize deglaciation (~16–11.5k cal a bp) when the lake was still closed but lake levels were higher. A rapid decline between ~11 and 10.5k cal a bp indicates that lake levels rose to overflowing. Lake δ18O values are interpreted to reflect the combined effects of changes in lake hydrology, growing season temperature and meteoric source water as well as large‐scale environmental changes impacting this site, including opening of the Bering Strait and shifts in atmospheric circulation patterns related to ice‐sheet dynamics. The results indicate significant shifts in precipitation minus evaporation across the late Pleistocene to early Holocene transition, which are consistent with temporal patterns of vegetation change and paludification. This study provides new perspectives on the paleohydrology of eastern Beringia concomitant with human migration and major turnover in megafaunal assemblages.

AbstractMany countries are having increased frequency and severity of wildfires, including mega‐fires. The revegetation of postfire sites and tree species selection are the most important counteracting measures. In this study, we analyzed the effect of tree species (Scots pine, European larch, common birch) on the C stock, macronutrient content, and physicochemical parameters (pH, sorption complex properties) of regenerated soil of different textures (sands and loams) in a large, postfire site. Nearly, 30 years after the fire, soils differed among the species. The carbon stock under larch was higher in litter (Oi + Oe) horizons than under birch. In mineral horizons (0–5 cm), the C stock was highest under birch. Litter layers under birch had a higher pH, a lower C:N ratio, and higher N, P, Ca, and Mg content compared to layers under pine and larch. In the A‐horizons (0–5 cm), soils under birch was higher in soil organic carbon (SOC), cation exchange capacity (CEC), and acidity than soils under conifers. Soil texture in the studied range—from sands to loams—had only a limited effect on the properties of the studied postfire soils. Thus, our results indicate that the tree species used for the reforestation of postfire sites are crucial to the properties of regenerating soils and restoring the ecological functions of soils. Among the studied tree species, common birch had the most pronounced effect on soil properties, and this is especially significant because the species has appeared by spontaneous succession.
Defining what constitutes a reliable dataset to test for hybridization and introgression in marine zooplankton: Comment on Choquet et al. 2020 “No evidence for hybridization between Calanus finmarchicus and C. glacialis in a subarctic area of sympatry”

AbstractThe article ‘No evidence for hybridization between Calanus finmarchicus and C. glacialis in a subarctic area of sympatry’ (Choquet et al. 2020) concludes that “no evidence supports a potential for hybridization between C. finmarchicus and C. glacialis”. We argue that the InDel markers used by Choquet et al. (2020) may have limited capacity to detect admixed genotypes between C. finmarchicus and C. glacialis due to an inappropriate choice of reference sample for each species during the marker development. We first review terms and concepts used in genetic classification using reference samples and describe problems associated with the selection of genetic markers in the context of possible hybridization. We reanalyze InDel genotypes provided with Choquet et al. (2017) and identified an admixed individual. We then contrast methods used by Choquet et al. (2017) and Parent et al. (2012) and explain how Parent et al. (2012) developed microsatellite markers capable of discriminating admixed genotypes from parental species. In this comment, we have identified a major issue that must be considered when selecting reference samples in the context of testing for possible hybridization.
Personal information disclosure on social networking sites

Published: September 2021

AbstractThe rapid growth in consumers' adoption of social networking sites revolutionized the marketing landscape, transforming the way brands communicate with their customers. At the same time, the widespread popularity of social networking sites raised major concerns about the privacy and security of users' personal information on these platforms. Drawing on social identity, and privacy calculus theories, this study examines the roles of consumer‐social networking site relational dimensions, namely personal information disclosure and social networking sites identification as drivers of consumer brand engagement on social networking sites‐hosted brand pages. We show that the extent of consumer‐social networking site identification and the degree to which consumers disclose personal information on a social networking site affect their engagement with other brands hosted on that platform. Online survey data collected from a nationally representative sample of US consumers (n = 506) and empirically tested through structural equation modeling provide overall support to the proposed model. This study contributes to the literature by being the first to empirically demonstrate the spillover effects of consumer‐social networking site relational attributes to online consumer brand engagement. The findings provide guidance to marketing managers seeking to increase brand engagement on social media.

Published: September 2021

ABSTRACTThe relative importance of antimuscarinic anticholinergic medications for Parkinson's disease (PD) declined after the introduction of levodopa, such that anticholinergic medications are now much more likely to be prescribed for clinical indications other than parkinsonism. Recent studies have found an association between anticholinergic medication exposure and future risk of dementia in older individuals and those with PD. These findings provide a further reason to avoid the use of anticholinergic medications to treat motor symptoms of PD. More importantly, they raise the question of whether one of the goals of PD treatment should be to deprescribe all medications with anticholinergic properties, regardless of their indication, to reduce dementia risk. In this review, we discuss the use of anticholinergic medications in PD, the evidence supporting the association between anticholinergic medications and future dementia risk, and the potential implications of these findings for clinical care in PD.

AbstractBackground8q21.11 microdeletion syndrome is a rare chromosomal disorder characterized by recurrent dysmorphic features, a variable degree of intellectual disability and ocular, cardiac and hand/feet abnormalities. To date, ZFHX4 is the only candidate gene implicated in the ocular findings. In this study, we evaluated a patient with a de novo 8q21.13–21.3 deletion to define a new small region of overlap (SRO) for this entity.MethodsWe conducted a clinical evaluation and comparative genomic hybridization (CGH) 4x44K microarrays in a patient with de novo unbalanced translocation t(8;16)(q21; q11.2).ResultsThe case, a 6‐year‐old boy, presented dysmorphic features including an elongated face, brachycephaly with a high forehead, an underdeveloped ala, thin upper lip, micrognathia, low‐set ears, hypotonia, mild intellectual disability, cortical atrophy with thin corpus callosum defect, and an atrial septal defect. No ocular abnormalities were found. Microarray analysis revealed a 9.6 Mb interstitial 8q21.11–21.3 deletion, not including the ZFHX4 gene. This microdeletion was confirmed in our patient through qPCR analysis, and both parents had a normal profile. Alignment analysis of our case defined a new SRO encompassing five genes. Among them, the HEY1 gene is involved in the embryonic development of the heart, central nervous system, and vascular system. Hrt1/Hey1 null mice show perinatal lethality due to congenital malformations of the aortic arch and its branch arteries. HEY1 has also been linked to the maintenance of neural stem cells, inhibition of oligodendrocyte differentiation, and myelin gene expression.ConclusionHEY1 is a candidate gene for both neurological and cardiac features of the 8q21.11 microdeletion syndrome and might, therefore, explain specific components of its pathophysiology.

Published: September 2021

AbstractA wideband multilayer filter with frequency tunable characteristics is proposed using active frequency selective surface (AFSS). The proposed AFSS includes three metal layers, while the top and bottom metal layers are embedded with varactors. The metal layers are separated by dielectric layers. By simultaneously adjusting the bias voltage loaded on both ends of the varactor diode, the working bandwidth of the AFSS can be continuously tuned. The operating mechanism is studied using an equivalent circuit, which is composed of an LC series resonance circuit and a parallel resonance circuit. The simulation results prove that the proposed AFSS performs wideband filtering in the frequency range of 3.55 to 4.43 GHz without a bias voltage. With a bias voltage of −19 V, the AFSS working passband is tuned to 4.43 to 5.53 GHz. Simulation and experimental results show that the AFSS has wideband filtering characteristics and good tunable performance.

Abstract
Artificial reefs are commonly used to provide structured habitat in areas with limited natural habitat to enhance the environment. Creating artificial reefs is expensive, and materials are often limited; thus, discussions are needed regarding the best material and design to maximize reefing efficiency while best meeting the goal of reefing programs. We tracked Red Snapper Lutjanus campechanus, an economically important and reef-dependent species, by using a Vemco Positioning System to determine fine-scale movements and habitat use around a nearshore reef comprised of three types of reefing structure: concrete reef pyramids, concrete culverts, and a sunken ship. Habitat use (core volume and home range, or the probability of a fish being absent 50% or 5% of the time, respectively) was significantly different by month, with the largest movements during summer months. Mean depth values also differed by study month (February–August), with Red Snapper residing deepest in the water column during August and shallowest during April. In the summer months, differences among structure types were observed in core volume use but not home range, suggesting that Red Snapper used similar-sized areas on all three structure types. A high reported recapture rate (77%; 10 of 13 fish) indicated that these easily accessible nearshore reefs undergo heavy fishing pressure. Half of the recaptures were reported as recaptured on a structure other than their tagging structure; however, tagged fish spent the greatest percentage of time on their tagging structure. Red Snapper habitat use was influenced more by the presence of structure than by the type of reefing structure. Using the results from this study combined with a cost comparison of reef types, we argue that use of the least expensive reefing material that covers the largest area may be the best policy in designing future artificial reefs.
Synthesis of dual pH‐ and temperature‐sensitive poly(N‐isopropylacrylamide‐co‐acrylic acid)/sewage sludge ash hydrogel with the simultaneously high performance of swelling and deswelling

AbstractAn advanced dual pH‐ and temperature‐sensitive hydrogel (NASH2.5) was optimally synthesized through modification of N‐isopropylacrylamide (NIPAM) hydrogel with introducing 5 mol% acrylic acid (AA) and 2.5 wt% sewage sludge ash (SSA). The swelling kinetic results showed that NASH2.5 exhibited both high equilibrium swelling ratio and swelling rate, which was attributed to the higher porous structure as shown in scanning electron microscope, and the more hydrogen bonding formed inside of the hydrogel as investigated in Fourier transform infrared spectrometer. In addition, its curve was better fitted to the pseudo‐second‐order model, indicating that the water absorption process was dominated by chemisorption through forming the hydrogen bonding among the water molecules and carboxyl/silanol groups of the hydrogel. Compared with the pure NIPAM hydrogel, the water transport mechanism switched from Case I diffusion to Case II diffusion by introduction of AA and further SSA. Furthermore, through the results of the deswelling kinetics in pH value change (from 9 to 4 and 2, respectively), temperature value change (from 25 to 40, 50, and 60°C, respectively), and dual pH and temperature values changes, NASH2.5 not only presented a high pH sensitivity, but also showed high sensitive to temperature by achieving high water recovery ratio in rapid dehydrated rate. Therefore, the dual stimuli‐sensitive hydrogel with the simultaneously high performance of swelling and deswelling would provide a suitable alternative for specific applications such as pollutant adsorption.
