Published: August 2023

AbstractTo examine how knowledge-based dynamic capabilities relate to firm performance through the mediating role of entrepreneurial orientation, we analyzed data of a sample of 1047 Portuguese and Spanish small and medium-sized enterprises (SMEs) of all industry sectors. The results reveal that knowledge-based dynamic capabilities are associated with firm performance and that the relationship is partially mediated by a firm’s entrepreneurial orientation. This mediation could be explained by the fact that an entrepreneurial orientation to identify and utilize new opportunities is integral to knowledge value creation and extraction, and to avoid pervasive rigidities. Our study sheds light on the mechanisms through which knowledge-based dynamic capabilities are associated with firm performance and helps to explain performance differences among firms. In addition, we provide management insight on how firms can deploy their knowledge-based dynamic capabilities and extract value from them to face change and promote their entrepreneurial orientation and performance.

Published: August 2023

AbstractAdvanced soft ion-conducting hydrogels have been developed rapidly in the integrated portable health monitoring equipment due to their higher sensitivity, sensory traits, tunable conductivity, and stretchability for physiological activities and personal healthcare detection. However, traditional hydrogel conductors are normally susceptible to large deformation and strong mechanical stress, which leads to inferior electro-mechanical stability for real application scenarios. Herein, a strong ionically conductive hydrogel (poly(vinyl alcohol)-boric acid-glycerol/sodium alginate-calcium chloride/electrolyte ions (PBG/SC/EI)) was designed by engineering the covalently and ionically crosslinked networks followed by the salting-out effect to further enhance the mechanical strength and ionic conductivity of the hydrogel. Owing to the collective effects of the energy-dissipation mechanism and salting-out effect, the designed PBG/SC/EI with excellent structural integrity and robustness exhibits exceptional mechanical properties (elongation at break for 559.1% and tensile strength of 869.4 kPa) and high ionic conductivity (1.618 S·m−1). As such, the PBG/SC/EI strain sensor features high sensitivity (gauge factor = 2.29), which can effectively monitor various kinds of human motions (joint motions, facial micro-expression, faint respiration, and voice recognition). Meanwhile, the hydrogel-based Zn∥MnO2 battery delivers a high capacity of 267.2 mAh·g−1 and a maximal energy density of 356.8 Wh·kg−1 associated with good cycle performance of 71.8% capacity retention after 8000 cycles. Additionally, an integrated bio-monitoring system with the sensor and Zn∥MnO2 battery can accurately identify diverse physiological activities in a real-time and noninvasive way. This work presents a feasible strategy for designing high-performance conductive hydrogels for highly-reliable integrated bio-monitoring systems with excellent practicability.
Additive Manufacturing of Locally Weakened Parts to Obtain a Designed Fracture
Authors: Galati Manuela , Defanti Silvio 
Published: August 2023

AbstractToday, the additive manufacturing (AM) approach has led to profound changes in part and process design, enabling previously impossible material properties. With the freedom to create the material as components are built layer by layer, AM has permitted precise spatial control of the material properties in manufactured parts. In this work, an original approach is proposed to locally control component and process design and create intentionally weakened regions with designed fracture, which paves the way to tuneable mechanical properties. Tensile tests of specimens with embedded weakened area of various geometries are used to verify the feasibility of a-priori-designed fracture modes and to characterise the variation in material behaviour. The results show that an ad hoc design of the artificially weakened areas is effective for predictable breakage, with load and strain being the precursor for active control of the mechanical behaviour. The attainability of a quantitative relationship between the defect and the mechanical response is exemplified by the fact that, e.g. for a flat geometry, the maximum stress and strain are reduced by half when the thickness of the weak region is doubled.

Abstract
Introduction
Drug use behaviors are closely associated with increased risk for HIV and other STIs among men who have sex with men (MSM) globally. Less is known about the drug use characteristics and their association with HIV/STI risk among MSM in Mexico, who have 13 times higher risk of acquiring HIV than the general population. We characterized distinct classes of drug use behaviors among a nationwide sample of MSM in Mexico and tested their associations with HIV risk behaviors.

Methods
We used latent class analysis (LCA) to analyze injection/non-injection drug use data collected by the online Encuesta de Sexo Entre Hombres self-administered survey among 15,875 MSM living in Mexico between May-June 2017. MSM were recruited on general social media sites (e.g. Facebook and Twitter), popular LGBT + focused web pages (e.g. Soy Homosensual and Desastre), and dating apps (e.g. Grindr and Hornet). We used robust Poisson regression to examine associations between drug use classes and recent sexual risk behaviors while adjusting for sociodemographic characteristics.

Results
Most participants were under 30 years of age (65.5%), received a Bachelor’s degree or higher (65.2%), gay-identified (82.5%), HIV negative (58.1%), and lived in the Mexico City/State of Mexico region (34.5%). We identified five distinct drug use classes: Limited Drug Use (75.4%), Marijuana Only (15.1%), Sex Event Popper + Marijuana (4.3%), Club Drug + Marijuana (4.2%), and Elevated Polydrug Use (1.0%). Compared to the Limited Drug Use class, participants in all other drug use classes were significantly more likely to engage in condomless anal intercourse (aPR = 1.14–1.39; p < 0.001), sex exchange (aPR = 1.37–4.99; p < 0.001), anonymous sex (aPR = 1.22–2.01; p < 0.001), group sex (aPR = 1.50–3.28; p < 0.001), and report an STI diagnosis in the past 12 months (aPR = 1.24–2.20; p < 0.002). Estimates were largest among the Elevated Polydrug Use class.

Conclusions
This study is the first to characterize drug use behaviors and HIV/STI risk among a national sample of MSM in Mexico. Understanding how distinct combinations of drug use behaviors impact sexual risk and prevention behaviors among MSM can inform how best to target and tailor future interventions to reduce HIV/STI incidence.

AbstractThe western honey bee is highly valued for its important role as natural pollinator. In Morocco, pollination services of Apis mellifera along with other insect pollinators were estimated at 1.2 billion US$. Regrettably, biological stressors including pathogens are leading factors contributing to colony losses and hampering pollination services. The aim of this study was to investigate the occurrence and prevalence of four agents responsible for nosemosis and foulbrood diseases in the oases of southeastern Morocco. Using polymerase chain reaction (PCR), we have analyzed 87 beehives sampled during two successive years from four provinces and representing two different beekeeping operation types, namely migratory (N = 51) versus stationary (N = 36). The results obtained revealed the absence of Nosema apis and Paenibacillus larvae. However, Nosema ceranae and Melissococcus plutonius were present at prevalence rates of 16.09% and 62.07% respectively. During the winter of 2020, there was higher prevalence rates of both pathogens compared to the winter of 2019. The province of Errachidia was free of N. ceranae, while the other three provinces were infected with different prevalence rates. On the other hand, M. plutonius was more prevalent in all four sampling areas. In addition, infection and co-infection patterns of N. ceranae and M. plutonius were found to be more prevalent in migratory beehives as opposed to stationary colonies. Results of this work constitute the first contribution to study infection patterns of nosemosis and foulbrood in Morocco, while more inquiries are needed in order to elaborate sustainable strategies for the beekeeping industry in Morocco.

Abstract
Introduction
The Scalp Eschar and Neck Lymph Adenopathy After a Tick Bite (SENLAT) syndrome is frequently caused by Rickettsia slovaca and Rickettsia raoultii. Only six microbiologically confirmed SENLAT cases have been reported in Italy between 1996 and 2021. We report ten cases of SENLAT seen between 2015 and 2022 in a tertiary care center in Tuscany, Italy.

Cases presentation
All patients were women; most common symptoms were scalp eschar on the site of tick bite (100%) and cervical lymphadenopathy (90%). No microbiological identification was obtained. Persistent alopecia, for several months to years, was observed in four patients. The known difficulty of microbiological diagnosis in SENLAT was worsened, in our cases, by factors as the absence of ticks available for identification and microbiological study, and antibiotic treatment administration previous to microbiological tests.

Conclusion
The report highlights the presence of SENLAT in Italy, aiming to raise the awareness toward the emergence of this clinical entity.

Published: August 2023

AbstractBreast cancer stands as the most frequent malignancy and leading cause of death among women. Early and accurate detection of this pathology represents a crucial factor in enhancing both incidence and mortality rates. Ultrasound (US) examination has been extensively adopted in clinical practice due to its non-invasiveness, affordability, ease of implementation, and wide accessibility, thus representing a valuable first-line diagnostic tool for the study of the mammary gland. In this scenario, recent developments in nanomedicine are paving the way for new interpretations and applications of US diagnostics, which are becoming increasingly personalized based on the molecular phenotype of each tumor, allowing for more precise and accurate evaluations. This review highlights the current state-of-the-art of US diagnosis of breast cancer, as well as the recent advancements related to the application of US contrast agents to the field of molecular diagnostics, still under preclinical study.
Watching Women Watch Sports and (re)Claim Their Fandom in Popular Culture
Authors: Symons Kasey 
Published: August 2023

AbstractThis conceptual paper explores the gendered framing of women as sports fans in literature and pop culture and the surveillance of their fandom in the stands. By investigating what it feels like to be watched while watching, and the complex ways in which gendered practices complicate the position of women as spectators of sport, we can see how some women are actively challenging the stereotypes of sports fandom in popular culture. Through using the method of reflexive autoethnography, (see Delamont, 2009; Ellis et al., 2010 and Holman Jones, 2016) this paper will re/address how women are framed as fans in the sports fan space and the activism they demonstrate in these presentations that has gone unnoticed and under-researched in the sports fan space.Through autoethnography I intend to also add personal reflections to connect to, challenge and re-position some representations of women as sports fans through this framework in order to explore different ways of engaging with the existing research. This method builds on innovative approaches to exploring fandom through mixed method and ethnographical investigations that have been developed in studies by key researchers in the field such as Hoeber & Kerwin’s (2013), McParland (2012) and Richards (2015 &, 2018).Applying the lens of reflexive autoethnography as the primary methodology will further allow me, an engaged participant myself, to re-explore my previous experiences to give gendered perceptions of sports fandom further nuanced consideration. This approach aims to offer alternative ways to consider how women show activism in challenging their surveillance and presenting their multi-layered and complicated experiences of fandom by re-viewing how women as fans are represented in popular culture.This paper will move through an examination of the existing research on gender and sports fandom, and touch on concepts of surveillance and present examples of women as fans in several text that perform elements of activism to challenge the ‘female fan’ stereotype to connect key ideas to the reflective autoethnographical entries, bringing a different way to understand the gendered experience of being watched while watching sport in a stadium.
Silicon Incorporation Reduces the Reactivity of Short-range Ordered Aluminosilicates Toward Organic Acids
Authors: Lenhardt Katharina R. , Stein Mathias , Rennert Thilo 
Published: August 2023

AbstractThe structure and composition of short-range ordered aluminosilicates (SROAS) may control their affinity for organic acids with potential effects on soil organic matter stabilization. Adsorption mechanisms of model organic acids were studied to resolve the effect of Si incorporation. Adsorption of oxalic, salicylic, and octanoic acid on Al-rich (Al:Si = 3.7) and Si-rich (Al:Si = 1.4) SROAS was quantified by analyses of dissolved organic carbon using catalytic high-temperature combustion. The initial pH of 5 and 6.5 increased to 6.3–8.2 during adsorption of oxalic and salicylic acid, demonstrating hydroxyl release by ligand exchange. Minor changes in pH indicated weak interactions of octanoic acid with both SROAS. Adsorbates were characterized by Fourier-transform infrared spectroscopy. Asymmetric stretching of carboxylate groups at 1720 and 1700 cm–1, and symmetric stretching at 1430 cm–1 evinced the formation of chelate complexes for oxalic acid. An absorption band centered at 1545 cm–1 indicated partial inner-sphere binding of salicylic acid on both SROAS. Silicon-rich SROAS adsorbed 80–90% less than Al-rich SROAS, suggesting that adsorption of oxalic and salicylic acid was controlled by surface aluminol groups. Fast kinetics of oxalate adsorption on Al sites was studied by a conductivity-based stopped-flow technique. Ligand exchange proceeded at a rate constant of 3.5 s–1 (25°C), similar to solute Al complexation, with an activation energy of up to 34.1 kJ mol–1. A slow process with a rate constant of 0.13 s–1 (25°C) was attributed to diffusion of oxalate at the surface or into SROAS particles. As supported by structural characterization of Si-rich SROAS, the much lower susceptibility of Si-rich SROAS to ligand exchange relates to Al speciation. The formation of tetrahedral Al precludes its complexation by carboxyl groups.
Smooth Operators, Predictable Glitches: The Interface Governance of Benefits and Borders
Authors: Raso Jennifer 
Published: August 2023

AbstractThis article examines the phenomenon of interface governance. It uses two interface technologies—Universal Credit’s digital account (United Kingdom) and ArriveCAN (Canada)—to explore how interfaces and their predictable glitches govern relations between state officials and members of the public. Drawing on tools of government literature, it argues that interfaces do not achieve their stated goals evenly (improved efficiency, digital literacy). Instead, they generate several unintended effects, including heightened bureaucratic intensity, diffused responsibility, and even eroded public trust in state agencies. It urges socio-legal and administrative justice scholars to take interfaces seriously and calls on scholars to adopt socio-legal-technical methods to better conceptualize the effects of infrastructure governance and to imagine other possibilities for public administration.
A quantitative assessment of ontogeny and molting in a Cambrian radiodont and the evolution of arthropod development
Authors: Moysiuk Joseph , Caron Jean-Bernard 
Published: August 2023

AbstractRadiodonta is a clade of stem euarthropods of central importance to our understanding of the evolution of this phylum. Radiodonts include some of the largest early Paleozoic animals; however, little is known about their ontogeny. We present an analysis of molting patterns and ontogeny in the radiodont Stanleycaris based on 265 exceptionally preserved specimens from the mid-Cambrian (Wuliuan) Burgess Shale. Ranging in size from 10 to 83 mm, they constitute the most extensive radiodont ontogenetic series known. Using a novel morphospace approach, we show that putative carcasses and exuviae can be quantitatively distinguished by the particular suites of structures preserved and their modes of preservation. We propose that Stanleycaris, and probably other radiodonts, molted via a suture near the anterior of the trunk. Similar anterior molting strategies, with a suture located at the head–trunk boundary, are shared with some Cambrian euarthropods and are potentially ancestral. Allometric analyses suggest that as Stanleycaris body size increased, the head sclerite and neck became relatively broader, while the trunk and flaps became slightly longer. The eyes developed precociously, indicating an important role of visual processing in juveniles. Finally, we find evidence for an initial anamorphic developmental phase, where segment number increased at least from 11 or 12 up to 17, followed by an epimorphic phase, in which growth continued without segment addition. This is consistent with the hypothesis that finite postembryonic segment addition (hemianamorphosis) is ancestral for arthropods and refines the timing of the origin of this important developmental mode.
Inferred nutrient forcing on the late middle Eocene to early Oligocene (~40–31 Ma) evolution of the coccolithophore Reticulofenestra (order Isochrysidales)

Published: August 2023

AbstractThe first size reduction (FSR) in the Reticulofenestra-Gephyrocapsa-Emiliania (RGE) lineage (order Isochrysidales), which occurred in the early Oligocene (~32 Ma), is of great significance for understanding the Lilliput effect that has affected coccolithophore communities from the late Eocene to this day. We conducted a morphologic analysis on the coccoliths of Reticulofenestra species that lived during the late middle Eocene to early Oligocene (~40–31 Ma), using marine sediments from the South Atlantic Ocean. Our data show increasing size and decreasing abundance of the large species during the late Eocene, leading to their disappearance at the FSR, and a concurrent decrease in the size variability of the small- to medium-sized coccoliths whose central opening diameter had become very reduced. Although the cosmopolitan late Paleogene through Neogene size decrease in coccolithophores has been linked to the concomitant long-term decline in global pCO2, we suggest here that the FSR was the result of environmental destabilization caused by the expansion of eutrophic environments following the late Eocene establishment of overturning circulation associated with ice buildup on Antarctica. This study also leads us to propose a hypothetical model that links coccolith morphology of species of the RGE lineage and trophic resources in the upper ocean: the small- to medium-sized, r-selected coccolithophores with smaller coccolith central openings live in nutrient-rich waters where they rely mostly on photosynthesis and little on mixotrophy, whereas the larger, K-selected species with larger coccolith central openings live in oligotrophic waters where they are more dependent on mixotrophy.
Personal Economic Shocks and Public Opposition to Unauthorized Immigration
Authors: Hopkins Daniel J. , Margalit Yotam , Solodoch Omer 
Published: August 2023

AbstractDo negative economic shocks heighten public opposition to immigration, and through what mechanisms? Extant research suggests that economic circumstances and levels of labour market competition have little bearing on citizens' immigration attitudes. Yet personal economic shocks have the potential to trigger the threatened, anti-immigration responses – possibly through channels other than labour market competition – that prior cross-sectional research has been unable to detect. To examine these propositions, we used a unique panel study which tracked a large, population-based sample of Americans between 2007 and 2020. We found that adverse economic shocks, especially job losses, spurred opposition to unauthorized immigration. However, such effects are not concentrated among those most likely to face labour market competition from unauthorized immigrants. Instead, they are concentrated among white male Americans. This evidence suggests that the respondents' anti-immigration turn does not stem from economic concerns alone. Instead, personal experiences with the economy are refracted through salient socio-political lenses.

AbstractAs the southernmost part of the central segment of the Central Asian Orogenic Belt, the northern Alxa area is characterized by abundant Permian magmatism and records key information on the geological evolution of the Palaeo-Asian Ocean. This study reports new zircon U–Pb and Lu–Hf isotopic and whole-rock geochemical data of the early Permian (285–286 Ma) Huisentala gabbro and Huodonghaer diorites from the Zhusileng–Hangwula Belt in the northern Alxa area. The gabbro is characterized by high Al, Ca, Mg#and light rare-earth elements, and low K, P and high field strength elements (e.g., Ti, Nb and Ta). Furthermore, the gabbro shows heterogeneous zircon ϵHf(t) value (−2.5 to +2.6). The Huodonghaer diorites show high MgO (3.46–6.32 wt%), Mg#(49–58), Sr (408–617 ppm) and Ba (223–419 ppm), and low FeOT/MgO (1.27–1.83) and TiO2(0.48–0.90 wt%), with geochemical features similar to the high-Mg andesite/diorite. They show radiogenic zircon ϵHf(t) values of +1.2 to +4.9 and high Th/Nb ratios. These features suggest that the Huisentala gabbro and the Huodonghaer diorites were derived from the partial melting of mantle peridotite that was metasomatized by subduction-related fluids and by subducted sediment-derived melts, respectively.
