Abstract
The life history of parasitoids is divided into a parasitic immature stage living in or on a host invertebrate and a free‐living adult stage. We still have little consensus on how larvae and adult parasitoids differ in their responses to environmental heat waves.
We tested the performance of two cosmopolitan drosophila pupal parasitoids, Pachycrepoideus vindemiae (Hymenoptera: Pteromalidae) and Trichopria drosophilae (Hymenoptera: Diapriidae), when exposed to 35 and 40°C heat waves in the larval and adult stage, respectively. Additionally, we tested if heat hardening in the larval stage influenced the thermal tolerance of adult parasitoids.
P. vindemiae had a higher tolerance to heat waves than T. drosophilae in both the larval and adult stages. We did not find significantly increased thermal tolerance of adult wasps that experienced heat hardening during the larval stage.
A 35°C heat wave had no effect on P. vindemiae. Larval T. drosophilae that experienced a 35°C heat wave had longer development times, but individuals that survived showed no significant decrease in longevity and fecundity compared with those without warming experience. By contrast, adult T. drosophilae suffered less mortality from the 35°C heat wave, but individuals that survived had significantly reduced longevity and fecundity. A 40°C heat wave resulted in higher mortality in the larval stage than in the adult stage for both parasitoid species.
Our study clearly revealed the contrasting responses to heat waves in the larval and adult stages of two parasitoids and highlighted the importance of ontogenetic differences in thermal tolerance in predicting parasitoid distributions and population dynamics.
Red gold: Copper and the U.S. mobilization campaign, 1950–3
Authors: Dorn Glenn J. 
Published: July 2024

AbstractThis paper examines U.S. planners’ persistent efforts to secure an adequate supply of a vital metal, copper, during the Korean War, and the numerous obstacles that plagued them. Their initial efforts to mobilize without imposing a disruptive, draconian control scheme quickly proved inadequate, all but forcing planners to adopt a much more regimented Controlled Materials Plan (CMP). The inability of U.S. planners to secure a strong supranational control regime through the International Materials Conference undercut efforts to coordinate international mineral allocation, exacerbated U.S. shortages, and spawned ill‐conceived compromises that eroded the effectiveness of the CMP. Finally, Truman's domestic opponents, never entirely reconciled to a rigid control regime, used the copper shortage to further weaken mobilization planning. In the end, the preparedness campaign, despite some remarkable successes, failed to achieve many of its goals due, in part, to a global copper shortage that Senator Burnet Maybank's Joint Committee on Defense Production called ‘perhaps the most serious material limiting factor on fulfillment of defense goals’.

AbstractCold‐water lakes situated in high latitudes and altitudes have pivotal socio‐ecological importance both globally and locally. However, they are increasingly threatened by multiple anthropogenic stressors, such as climate change, hydropower and invasive species. The development of efficient management strategies is therefore urgently needed and requires a comprehensive understanding of the factors influencing the biodiversity and ecological processes of these ecosystems. We provide a holistic knowledge base for informed future research and management by addressing the interplay between local and global environmental drivers of food webs in Arctic charr (Salvelinus alpinus, Salmonidae) and brown trout (Salmo trutta, Salmonidae) dominated cold‐water lakes in Fennoscandia. The trophic niche and population dynamics of these generalist top consumers provide extensive insights into the effects of natural and anthropogenic drivers on food webs in intensively studied Fennoscandian cold‐water lakes, covering marked biogeographical gradients in abiotic and biotic conditions. Drawing on a synthesis of existing literature, our focus is on three pivotal drivers: (1) lake location and connectivity, (2) lake area and morphometry and (3) fish community composition. These drivers significantly influence the complexity and the origin and flow of energy in lake food webs, and ultimately the size structure of the charr and trout populations. Furthermore, we highlight ongoing environmental changes in Fennoscandian cold‐water lakes caused by hydropower and invasive species. Finally, we identify crucial knowledge gaps and propose management actions for improving the future state of Fennoscandian cold‐water lake ecosystems and their charr and trout populations.

Published: July 2024

AbstractThe objective of this research is to explore the scale effect on the mechanical properties of sheet‐based triply periodic minimal surface (TPMS) uniform lattice structures fabricated with PLA (polylactic acid) under quasi‐static loading conditions. The scale dependency was evaluated by two additional breakdown categories, namely, wall thickness effect and unit cell size effect. Deformation mechanisms and failure modes as well as mechanical properties including stiffness, yield strength, first peak stress, and energy absorption based on the categories of wall thickness, unit cell size, and scale were evaluated experimentally. The assessment of the scale effect involved considering the combined influence of wall thickness and unit cell size. In addition, numerical analysis was also performed to investigate the stress distributions and compare with the experimental results for certain geometries. Ultimately, the relation between the normalized mechanical properties and relative density is evaluated and categorized, which can be used as an indication for future design practices.

Published: July 2024

AbstractPer‐ and polyfluoroalkyl substances (PFAS) are persistent in the environment due to their chemical stability and can spread quickly in a lake system due to mixing. Passive samplers allow for time‐weighted average concentration monitoring and the ability to detect low concentrations, which are difficult to measure with conventional grab sampling. This study demonstrates the feasibility of deploying both ceramic dosimeters and Sediment Bed Passive Flux Meters (SBPFMs) to assess time integrated PFAS concentrations and fluxes, respectively, at a historically contaminated PFAS lake near Baden‐Baden, Germany. Long‐term surface water grab samples resulted in the detection of PFBA, PFPeA, PFHxA, PFHpA, PFOA, PFNA, PFDA, PFBS, PFHxS, and PFOS at a total concentration of approximately 1 μg/L. Dosimeters were deployed for 66 and 126 d, resulting in detected concentrations ranging from approximately 250 to 380 ng/L and 120 to 460 ng/L, respectively. The 66 d deployment resulted in the detection of PFPeA, PFHxA, PFHpA, and PFOA, whereas the 126 d deployment additionally detected PFBA, PFNA, PFDA, PFUnDA, PFDoDA, PFTeDA, PFBS, PFPeS, PFOS, PFNS, and PFDS. SBPFMs resulted in the detection of PFBA, PFPeA, PFHxA, PFHpA, PFOA, PFNA, PFUnA, PFTrDA, and PFBS and the determination of a total mass discharge of 5.6 g/d into the lake. Overall, dosimeters and SBPFMs are more sensitive than grab samples at detecting PFAS at low concentrations and can be used to better understand spatial distribution of PFAS in a lake system.

AbstractThis study aimed to compare and summarize the mullitization mechanism of the sillimanite group minerals and investigated its effect on the mechanical properties of Al2O3‐SiC‐C gunning materials. By comparing the phase composition and microstructure of kyanite, andalusite, and sillimanite at different temperatures, the mullitization mechanism of sillimanite group minerals was clarified. Furthermore, the Al2O3‐SiC‐C gunning materials with sillimanite group minerals addition were prepared by bauxite and fused brown corundum as aggregates, fused white corundum (≤0.045 mm), SiC (≤0.075 mm), α‐Al2O3 (≤10 µm), pitch sphere, SiO2 micropowder (≤2 µm) as a matrix, and silica sol as a binder. Then, the effect of the addition of sillimanite group minerals on the mechanical properties of Al2O3‐SiC‐C gunning materials was characterized. The results indicate that kyanite requires the lowest temperature for mullitization compared to andalusite and sillimanite. The mullitization process involves the migration of Al3+ and Si4+, resulting in a decrease in the lattice constant of sillimanite group minerals followed by the production of mullite and SiO2. Incorporating sillimanite group minerals into Al2O3‐SiC‐C gunning materials effectively controls their linear change rate after firing while enhancing their mechanical properties. Notably, the addition of kyanite yields superior performance in Al2O3‐SiC‐C gunning materials.

Published: July 2024

AbstractNi2+‐doped glass–ceramics containing Zn(GaxAlx−1)2O4 crystals were successfully synthetized using both parent glass crystallization (Technique 1) and a direct doping method also called “frozen sorbet” (Technique 2) to get a ZnGa2O4 crystal/glass composite. The frozen sorbet technique allows the survival of ∼10 nm crystalline particles. Both materials are further crystallized near their respective temperature of crystallization to get glass–ceramics with the stabilization of Zn(GaxAlx−1)2O4 crystals. Although these two materials exhibit the same glass transition temperature, a shift in the crystallization temperature is observed. The glass–ceramics are transparent in the near infrared range, and the Ni2+ doping provides a broadband emission centered around 1300 nm with a full width at half‐maximum (FWHM) equal to 228 nm. The structure, microstructure, and thermal and optical properties of these materials are discussed in the present study.
Does interlanguage grammar project intermediate categories? Evidence of partial representation from one‐substitution by Chinese learners of English
Authors: Ma Zhigang , Yu Xiaomei 
Published: July 2024

AbstractThis study investigates how prepositional phrases within English noun phrases (e.g., the student of physics from Italy) are represented and processed by advanced Chinese‐speaking learners of English (henceforth L2ers). Using grammaticality judgment tasks and self‐paced reading tasks, we aim to examine the offline performance and the real‐time processing of English NP‐internal PPs in relation to the head nouns. To this end, two groups of participants were instructed to provide judgments of testing materials and to respond on‐line to experimental stimuli containing the proform one. Results indicate that highly proficient L2ers processed English NP‐internal PPs utterly differently from English controls in that they demonstrated almost no sensitivity to the existence of PPs as complements following one, mostly without consciously distinguishing them from PP adjuncts. To account for L2ers’ response patterns, we propose a partial representation hypothesis (PRH), claiming that L2ers tend to disregard intermediate categories containing PP‐complements in English NPs, thus only partially representing syntactic constituents of the target language. As a structural explanation, PRH awaits further corroboration and/or falsification from more empirical studies.

Published: July 2024

AbstractThis study aimed to determine the effect of incontinence after radical prostatectomy on quality of life and level of frailty. It is a descriptive study conducted with 107 radical prostatectomy patients who were hospitalized in the Urology Clinic of a training and research hospital in Istanbul between March–August 2021, and met the inclusion criteria. Data were collected using the Patient Identification Form, the International Consultation on Incontinence Questionnaire – Male Lower Urinary Tract Symptoms (ICIQ‐MLUTS), and the Edmonton Frail Scale (EFS). The mean fragility score of the patients was 7.82 ± 2.63, and 27% of them were ‘Mildly Frail’ and 25.2% were ‘Moderately Frail’. The ICIQ‐MLUTS voiding complaints sub‐dimension score of the patients was 8.62 ± 3.48, and the voiding complaints bother score was found to be 24.8 ± 9.85. The ICIQ‐MLUTS storage complaints sub‐dimension score was 12.13 ± 3.05, and the storage complaints bother score was 36.25 ± 9.02. The ICIQ‐MLUTS daytime urinary frequency subdimension score was 2.35 ± 0.93, and the daytime urinary frequency bother score was 6.94 ± 2.17. The ICIQ‐MLUTS nocturnal urinary frequency sub‐dimension score was 2.79 ± 0.88, and the nocturnal urinary frequency discomfort level score was found to be 7.37 ± 2.19. In this study, it was observed that patients' complaints regarding lower urinary tract symptoms and their quality of life were at a moderate level and the frailty levels increased with the increasing severity of incontinence symptoms after radical prostatectomy.

Published: July 2024

AbstractInflammatory bowel disease (IBD) and food allergy (FA) increase in tandem, but the potential impact of IBD on FA remains unclear. We sought to determine the role of IBD on FA. We first assessed the changes of FA‐related risk factors in dextran sulphate sodium salt (DSS) induced colitis mice model. Then, we evaluated the role of IBD on FA in mice. FA responses were determined using a clinical allergy score, body temperature change, serum antibody levels, cytokines level and mouse mast cell protease 1 (MMCP‐1) concentration. Accumulation of regulatory T cells was tested using flow cytometry. Intestinal changes were identified by histology, immunohistochemistry, gene expression and gut microbial community structure. In DSS‐induced colitis mice model, we found the intestinal damage, colonic neutrophil infiltration, and downregulation of splenic Th2 cytokines and Tregs in mesenteric lymph nodes (MLN). Moreover, we also found that IBD can alleviate the FA symptoms and lead to the significant downregulation of Th2 cytokines, serum IgE and MMCP‐1. However, IBD exacerbates intestinal injury and promotes the gene expression levels of IL‐33 and IL‐5 in the small intestine, damages the intestinal tissue structure and aggravates intestinal dysbiosis in FA. IBD functions as a double‐edged sword in FA. From the perspective of clinical symptoms and humoral immune responses, IBD can reduce FA response by downregulating Th2 cytokines. But from the perspective of the intestinal immune system, IBD potentially disrupts intestinal tolerance to food antigens by damaging intestinal tissue structure and causing intestinal dysbiosis.

Published: July 2024

AbstractIn this paper, boron (B)‐doped biphasic calcium phosphate (BCP)/poly(vinylidene fluoride) (PVDF) membrane scaffolds were developed by the combination of non‐solvent induced phase separation and lyophilization processes. In addition, the effects of the synthesized B‐incorporated BCP powders on the properties of the fabricated scaffolds were investigated. The physicochemical and morphological properties of the scaffolds were characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy. The physical properties were evaluated by surface wettability and swelling measurements, whereas the mechanical properties were investigated by tensile strength measurements. The thermal behavior was determined by differential scanning calorimetry, the β‐crystallization ratio was calculated by FTIR, and the β‐phase structure was characterized by X‐ray diffraction. The bioactivity was evaluated in the simulated body fluid, and the cytotoxicity of the scaffolds was also investigated by performing in vitro cell culture experiments. The results showed that the incorporation of B into the PVDF matrix improved the hydrophilicity while reducing the degree of swelling of the scaffolds. Tensile strength was slightly reduced by the powder content, but yet the strength of all scaffolds was mechanically compatible with native bone. Increasing the B content up to 0.5 and 1 wt.% was improved the thermal properties, the β‐crystalline phase fraction, and thus the piezoelectricity. Furthermore, B‐doped BCP/PVDF‐based scaffolds significantly promoted bioactivity, cell viability, and proliferation without cytotoxicity, compared to the PVDF scaffold, depending on the B content. In conclusion, our results indicate that the PVDF‐based composites in the form of membrane scaffolds that support bone growth have the potential to be highly sought‐after candidates in the field of biomedical applications.

AbstractAimsTo explore levers and barriers to providing culturally responsive care for general practice nurses (GPNs) using normalization process theory.DesignA self‐administered online cross‐sectional survey.MethodsA participatory co‐designed adapted version of the normalization of complex interventions measure (NoMAD) validated tool was distributed to a convenience sample of GPNs between December 2022 and February 2023. The sample comprised of GPNs working in general practice services in Ireland (n = 122). Data were analysed using descriptive and analytical statistics (Pearson correlations) and principles of content analysis. This study was conducted and reported in line with the Consensus‐Based Checklist for Reporting of Survey Studies (CROSS).ResultsGPNs in this study indicated their familiarity with, acknowledged the importance of and were committed to, providing culturally responsive care. However, implementing culturally responsive care in daily practice was problematic due to insufficient education and training, scarcity of resources and supports and a lack of organizational leadership. Subsequently, GPNs experience difficulties adapting everyday practices to respond appropriately to the care needs of culturally and linguistically diverse (CaLD) patients.ConclusionThis analysis highlights the necessity of exploring the intricacies of factors that influence capabilities and capacity for providing culturally responsive care. Despite demonstrating awareness of the importance of providing nursing care that responds to the needs of CaLD patients, GPNs do not have full confidence or capacity to integrate culturally responsive care into their daily work practices.ImpactUsing normalization process theory, this study elucidates for the first time how GPNs in Ireland make sense of, legitimize, enact and sustain culturally responsive care as a routine way of working. It illuminates the multitude of micro‐level (individual), meso‐level (organizational) and macro‐level (structural) factors that require attention for normalizing culturally responsive care in general practice services.Patient or Public ContributionThe study question was identified in a participatory research prioritization for Irish research about migrant health that involved migrants in the process.
Regulating data: Evidence from corporate America
Authors: Motoki Fabio , Pinto Jedson 
Published: July 2024

AbstractUsing the enforcement of the General Data Protection Regulation (GDPR) as our empirical setting, we examine how stricter data privacy and data protection requirements affect shareholder wealth, firms’ investment decisions, and data breaches. Consistent with consumer privacy negatively affecting firms, we find that U.S. firms exposed to the GDPR lose 0.7%–1.1% in market value relative to unexposed firms in the week in which the regulation became enforceable. We find that the decrease in market value is partially attributable to a decrease in sales growth. GDPR‐exposed firms increase their investment above that of control firms and become less likely to report a data breach post‐regulation. The decrease in data breach likelihood is statistically and economically significant, resulting in up to 34 million records not being leaked, which costs between $205 million and $561 million to firms in breach mitigation expenses per year. The results of this study should be of interest to academics and regulators worldwide by examining the costs and benefits of regulating data.
Context Matters: Variation in the Shortsightedness of European Climate Policy
Authors: Gheuens Jana 
Published: July 2024

AbstractWhen governments are faced with long‐term issues like climate change, it is often argued that they bias the short term over the long term, leading to inadequate policy responses. However, the shortsightedness of European Union (EU) climate governance has varied over time and between policy areas. This suggests that, under certain conditions, EU policy‐makers can formulate policies for the long term. This article examines the shortsighted mechanisms in the decision‐making of the European Commission, European Parliament and Council of the EU on two groups of cases: (1) the 2030 Climate Framework and the Fit for 55 Package and (2) the 2014, 2019 and 2023 Regulations on the CO2 emission performance standards for new passenger cars. The article reveals that responsiveness to electoral and interest group concerns differs amongst EU institutions, and depending on the shortsightedness of these concerns, their own shortsightedness may likewise vary.
