Published: October 2024

AbstractInternational entrepreneurial orientation (IEO) and its potential impact on business performance in foreign markets has attracted significant research attention in recent years. However, few studies have attempted to examine how, and under what conditions, IEO results in enhanced performance for international firms. The present study aims to contribute towards filling this gap by investigating the internal mechanism through which IEO influences performance, considering the mediating effects of dynamic capabilities and international business strategy. Using data collected from 258 small‐ and medium‐sized enterprises (SMEs) that engage in international business activities, we find that IEO contributes to the frequent use of sensing and reconfiguring, which in turn fosters international strategy comprehensiveness and implementation speed. Our results also indicate that international strategy comprehensiveness and implementation speed have a positive impact on international market performance. These findings suggest that research on the impact of IEO on performance should explore how it influences firms' dynamic capabilities and examine the effect of these dynamic capabilities on business strategy. For entrepreneurs and managers of emerging market SMEs, our results indicate that IEO should guide international expansion efforts.
Technology acquisitions and investor expectations: Reputation and expectancy violation perspectives
Authors: Chaturvedi Tuhin 
Published: October 2024

AbstractEmploying the organizational reputation lens and expectancy violation theory (EVT), I examine how financial market investors (investors) affect the technology acquisition activity and the likelihood of survival of firms facing technological change. I theorize that when a firm has a growth reputation, that is, investors expect revenue growth in future periods, the likelihood of making an acquisition will increase in anticipation of a positive expectancy violation on the part of investors. In contrast, for a firm that has an income reputation, that is, investors expect shareholder returns in future periods, the likelihood of making an acquisition will decrease in avoidance of a negative expectancy violation on the part of investors. I predict a novel moderating effect of investor expectations—a firm's acquisition activity will exert a stronger positive effect on its likelihood of surviving technological change when investor expectations are growth‐oriented, that is, when there is a positive expectancy violation. Using a multi‐industry sample of industry convergence, a salient form of technological change, I find support for my theoretical predictions. I advance research that examines the reactions of investors to firm strategies during technological change to the domain of technology acquisitions, a salient strategic decision. I also expand the predictive utility of the reputation lens and EVT to the context of firm survival during technological change.

SummaryA 15‐year‐old Warmblood gelding was presented with recurrence of a histologically confirmed osteosarcoma of the left second and third metacarpal bones 3 years after initial diagnosis and treatment. Initially, surgical excision was performed, followed by local injection of carboplatin 11 weeks later. The horse was sound after surgery and was used for low‐level dressage and jumping. Three years later, the horse developed an acute onset of lameness in the left forelimb and a painful soft tissue swelling at the proximomedial metacarpal region. Radiographs showed a spiculated periosteal reaction on the medial aspect of the third metacarpal bone, indicating re‐activation of the lesion. Stereotactic radiation therapy was performed with a protocol consisting of three fractions under general anaesthesia (Mo‐We‐Fr schedule), and a total dose of 30 Gy. The technique used was volumetric‐modulated arc therapy guided by cone beam computed tomography for daily positioning. Following the radiation therapy, the horse became sound at walk, and 1 month later, it became sound at trot. Follow‐up by veterinary examination 18 months after final treatment revealed no lameness at walk and trot, and a stable radiographic appearance.

Published: October 2024

AbstractThe surface morphology has a significant influence on the fatigue behavior of components. For austenitic stainless steels (ASSs), this issue is even more pronounced due to their metastability. Based on the complex deformation mechanisms of metastable ASSs, which include dislocation slip, deformation twinning, and deformation‐induced martensitic phase transformation, the metastable stainless steel AISI 347 was investigated in this study together with the stable AISI 904L as a reference material. Four‐point bending fatigue tests with load ratio R = 0.1 and testing frequency f = 10 Hz at ambient temperature were carried out on specimens with five technically relevant surface morphologies: mechanical polished, milled, microshot peened, laser shock‐peened, and ultrasonic modified. Systematic material characterizations were carried out to elucidate the crucial role of surface roughness and deformation‐induced α′‐martensite in the fatigue behavior of both metastable and stable materials. While surface roughness is a well‐known key factor in conventional fatigue cases, deformation‐induced martensite layers implemented by various surface modification methods were proven to improve the fatigue life in metastable austenitic steels, opening new perspectives to extend the lifetime of ASS components.
Bait Biomass and Caloric Contribution From the Dungeness Crab (Cancer magister) Fishery in Oregon, USA
Authors: Harbison Toby , Henkel Sarah K. 
Published: October 2024

ABSTRACTFishery discards worldwide increase the availability of organic materials on the benthos, altering trophic relationships and potentially increasing the abundance of benthic consumers. Expert knowledge from fishers is a valuable yet often underutilized source of information to understand these dynamics. We interviewed Dungeness crab fishers (n = 24) to determine the most‐used bait types and to characterize regional and seasonal bait use strategies that drive inputs of organic matter into Oregon coastal waters during the commercial Dungeness crab fishery each year. Based on bomb calorimetry measurements of caloric densities of 12 commonly reported bait species, total energetic input was 12.99 × 109 kJ (3.10 B kcal) from bait in the 2019–2020 commercial ocean Dungeness season in Oregon, USA. Fishing effort and bait inputs were strongly seasonal, with 88% of effort concentrated in the first 60 days of the 9‐month‐long season but did not vary regionally. This large, temporally concentrated caloric input suggested that bait could contribute substantially to Dungeness crab productivity. Fisher respondents indicated that bait effectiveness was the most important motivating factor in choosing a bait type, more than availability or cost.

ABSTRACTAimBiogenic structural complexity increases mobile animal richness and abundance at local, regional and global scales, yet animal taxa vary in their response to complexity. When these taxa also vary functionally, habitat structures favouring certain taxa may have consequences for ecosystem function. We characterised global patterns of epifaunal invertebrates in eelgrass (Zostera marina) beds that varied in structural and genetic composition.LocationNorth America, Europe and Asia.Time Period2014.Major Taxa StudiedPeracarid crustaceans and gastropod molluscs.MethodsWe sampled epifaunal invertebrate communities in 49 eelgrass beds across 37° latitude in two ocean basins concurrently with measurements of eelgrass genetic diversity, structural complexity and other abiotic and biotic environmental variables. We examined how species richness, abundance and community composition varied with latitude and environmental predictors using a random forest approach. We also examined how functional trait composition varied along with community structure.ResultsTotal species richness decreased with latitude, but this was accompanied by a taxonomic shift in dominance from peracarid crustaceans to gastropods, which exhibited different sets of functional traits. Greater eelgrass genetic diversity was strongly correlated with both richness and abundance of peracarids, but less so for gastropods.Main ConclusionsOur results add to a growing body of literature that suggests genetic variation in plant traits influences their associated faunal assemblages via habitat structure. Because peracarids and gastropods exhibited distinct functional traits, our results suggest a tentative indirect link between broad‐scale variation in plant genetic diversity and ecosystem function.
A Life's Work? Unpacking the Existential Meaning of Educational Mobilities for Migrant Families
Authors: Waters Johanna L. 
Published: October 2024

ABSTRACTIt is axiomatic that middle‐class Asian migrant families invest heavily—practically and emotionally—in their children's education. Scholarship has linked this investment to strategies of capital accumulation. There has been little discussion, however, about the transformative nature of these strategies and how they might be framed in terms of migrants' whole lives. This paper applies theoretical concepts from migration studies and a framework proposed by philosopher Charles Taylor, to argue that educational migration should be seen as profoundly life shaping.
Search for putative gene regulatory motifs in CAHS3, linked to anhydrobiosis in a tardigrade Ramazzottius varieornatus, in vivo and in silico
Authors: Ishikawa Sora , Tanaka Sae , Arakawa Kazuharu 
Published: October 2024

AbstractTardigrades possess the ability to enter an almost completely dehydrated state, anhydrobiosis. The CAHS (cytosolic abundant heat‐soluble) protein family has been identified as one of the anhydrobiosis‐related proteins. In particular, CAHS3 protein from an anhydrobiotic tardigrade, Ramazzottius varieornatus, shows heat‐solubility and reversible condensation and is one of the most highly expressed among the CAHS paralogs. A recently developed tardigrade‐specific vector showed tissue‐specific expression of RvCAHS3 most pronounced in the epidermis in vivo, contrary to the idea that anhydrobiotic genes are uniformly expressed in all tardigrade cells. In this study, we investigated the regulation of RvCAHS3 gene expression through in vivo expression experiments using tardigrade vectors with a series of truncated upstream regions coupled with in silico analysis to identify the anhydrobiosis‐related genes that are expressed under the same regulatory system as RvCAHS3. As a result, the 300–350 bp region upstream of RvCAHS3 is critical for regulating gene expression in tardigrade vector experiments, and three motifs conserved between two species of anhydrobiotic tardigrades were identified within a 500 bp region directly upstream of RvCAHS3 start codon. These motifs, which have also been identified upstream of other CAHS genes, could be associated with the regulatory system of anhydrobiosis‐related genes in tardigrades.

Published: October 2024

AbstractThe energy consumption of MOS (metal oxide semiconductor) sensors has always been a challenge in improving their performance. In this study, bougainvillea‐like Au/ZnO nanostructures were successfully synthesized using the hydrothermal method and the sol fixation technique. The composition, crystallinity, crystal structure, and morphology of the materials were characterized using X‐ray diffraction, energy‐dispersive spectroscopy, and field emission scanning electron microscopy. The experimental results confirm the successful synthesis of a substantial quantity of bougainvillea‐like Au/ZnO nanostructures through nanoparticle self‐assembly. The sensitive performance of the bougainvillea‐like Au/ZnO sensor was evaluated using a CGS‐8 intelligent gas‐sensitive analysis system. Results demonstrate that modification of ZnO with Au in a bougainvillea‐like nanostructure significantly enhances sensitivity to ethanol vapor compared to those of unmodified material sensors. Specifically, the optimal work temperature was greatly reduced by 64%, whereas the sensitivity increased approximately 12 times and the response time decreased nearly 5 times. The significantly enhanced ethanol sensitivity can be attributed to the precious metal modification and unique three‐dimensional morphology. It provides the necessary experimental exploration for reducing energy consumption and improving the performance of MOS gas sensors.
Extrusion‐based additive manufacturing of alumina ceramics through controlled extrusion pressure
Authors: Chandan Palivela Bhargav , Sankar Mamilla Ravi 
Published: October 2024

AbstractThe development of dense alumina ceramics through additive manufacturing necessitates the careful analysis of various parameters. The extrusion pressure during printing is a crucial but often overlooked factor in the literature. This study investigates the impact of extrusion pressure on the densification and mechanical properties of alumina ceramics. The primary objective is to analyze extrusion pressure to achieve superior physical and mechanical characteristics while maintaining minimal shrinkage. All other printing parameters were kept constant, and the extrusion pressure was varied from 1 to 2.85 bar during the extrusion‐based additive manufacturing of alumina green bodies. The printed and sintered samples were analyzed for linear shrinkage, density, compressive strength, and microhardness. The results indicate that an extrusion pressure in the 2.2–2.5 bar range leads to alumina ceramics with the best combination of densification and other mechanical properties. Additionally, the interparticle bonding mechanisms contributing to the improved properties of the alumina ceramics were examined. This study provides valuable insights into the role of extrusion pressure in the additive manufacturing process, underscoring its significance in achieving high‐quality alumina ceramics.
Preparation, characterization, and catalytic performance comparison of Ni/LaBO3 and Ru‐Ni/LaBO3 (B = Al, Fe) for methane steam reforming to hydrogen production

Published: October 2024

AbstractThe methane steam reforming (MSR) reaction is a significant process for hydrogen production, and developing catalysts with high activity and stability is crucial. In this work, the supported perovskite catalysts of Ni/LaBO3 and Ru‐Ni/LaBO3 (B = Al, Fe) were prepared by the sol–gel method using citric acid as a gelling agent for MSR to hydrogen production. The phase composition, pore structure, and surface morphology of the prepared catalysts were characterized by X‐ray diffractometer, Brunauer–Emett–Teller, scanning electron microscopy and energy dispersive spectroscopy, and X‐ray photoelectron spectroscopy. The reaction activity and stability of the prepared catalysts were tested in the fixed‐bed reactor with the temperature range of 500–800°C. The effect of Ru addition on the structure of perovskite and catalytic performance of MSR is explored. The results showed that 1wt%Ru–15wt%Ni/LaAlO3 catalyst exhibited the most excellent activity and stability during the reaction compared with the other three catalysts. The CH4 conversion, H2 selectivity, and H2 yield of the 1wt%Ru–15wt%Ni/LaAlO3 catalyst could reach 94.68%, 79.78%, and 48.65%, respectively, under the reaction temperature of 800°C and gas hourly space velocity of 36 000 mL/(gh), which were higher than those of a commercial catalyst. It was because that the relatively large surface area of perovskite support provides more active site and the addition of Ru enable Ni to have a smaller size and more dispersion. This study could provide a reference of perovskite catalysts for hydrogen production by MSR.

ObjectivesThis study aimed to investigate the potential for using the phosphatase and tensin homolog (PTEN) gene as a prognostic marker in post‐prostatectomy patients with castration‐sensitive prostate cancer (PCa).MethodsA total of 180 patients with castration‐sensitive PCa who underwent radical prostatectomy at our institution were included in this study. PTEN expression was evaluated using immunohistochemistry, and patients were classified into two groups based on the staining intensity: PTEN‐Normal and PTEN‐Loss. The association between PTEN expression and biochemical recurrence was analyzed using the Cox proportional hazards model.ResultsPatients in the PTEN‐Loss group had a higher risk of biochemical recurrence (hazard ratio, 4.642; 95% confidence interval, 2.137–10.083; p < 0.001) and a lower recurrence‐free rate compared to the PTEN‐Normal group (35% vs. 75%). In addition to clinicopathological factors, such as the serum prostate‐specific antigen level, Gleason score, and T stage, evaluation of PTEN expression improved the prediction of biochemical recurrence after prostatectomy (area under the curve, 0.577 vs. 0.688).ConclusionsLow PTEN expression is a significant predictor of biochemical recurrence in patients with castration‐sensitive PCa who have already undergone prostatectomy.
The role of cytoreductive nephrectomy in the era of immune checkpoint inhibitors: A review of current evidence and ongoing trials
Authors: Hara Takuto , Miyake Hideaki 
Published: October 2024

AbstractRenal cell carcinoma (RCC) was diagnosed in over 400 000 individuals globally in 2020, making it a significant global health concern. The incidence of RCC varies by region and overall mortality rates have been declining. This decline is attributed in part to advancements in early cancer detection through imaging and the development of more effective systemic therapies. Cytoreductive nephrectomy (CN) was adopted as a standard treatment for metastatic RCC (mRCC) based on clinical experience and early clinical trials. However, the treatment landscape has shifted with the introduction of tyrosine kinase inhibitors (TKI) in 2007 and, more recently, immune checkpoint inhibitors (ICIs). Dual ICI therapy and combinations of ICIs with TKIs are collectively referred to as immuno‐combination therapies and have become standard first‐line treatments. This review examines the evolving role of CN in the era of immuno‐combination therapies, with a focus on patient selection and the timing of surgery. The immunogenic nature of RCC, characterized by spontaneous tumor regression and immune cell infiltration, suggests a potential benefit from combining CN with ICI therapy to enhance treatment outcomes. This is supported by several clinical studies that reported improved outcomes; however, these were limited by their retrospective nature. Ongoing clinical trials, such as NORDIC‐SUN, PROBE, and SEVURO‐CN, are expected to provide critical insights into the role of CN in the ICI era. Their findings will ultimately guide future clinical decision‐making and further refine treatment strategies for mRCC.
An adaptation of Random Forest to estimate convex non‐parametric production technologies: an empirical illustration of efficiency measurement in education
Authors: España Victor J. , Aparicio Juan , Barber Xavier 
Published: October 2024

AbstractThis paper presents a novel approach to conduct non‐parametric estimations of production technologies that adhere to the basic assumptions of production theory axioms, including free disposability in inputs and outputs and convexity. The methodology is rooted in adapting the highly effective machine learning techniques associated with Random Forest and the use of splines. The new method features a piecewise linear estimator analogous to data envelopment analysis (DEA); however, it distinguishes itself by addressing DEA's overfitting and lack of robustness via randomization of data and input variables in the construction of the models. In this paper, the virtues of employing machine learning techniques for assessing the efficiency of public services, particularly in the realm of educational institutions, are underscored. The new approach has the capability to predict outputs based on inputs, even for units not included in the observed sample. Furthermore, it enables the identification of the most relevant inputs in relation to output production. To demonstrate the advantages of our method, an estimation of the educational production function is conducted for Spanish regions utilizing data sourced from the Program for International Student Assessment.

Published: October 2024

AbstractNative freshwater mussel (Unionidae) mortality events have been occurring with increased frequency in recent decades, with few investigations into potential etiological agents. In the western United States, no surveys have been published regarding the bacteria associated with unionid mussels. Herein, we examine locations of known mussel mortality events in the Chehalis River (Washington), in the Crooked River (Oregon), and Owyhee River (Oregon). Mussel populations considered healthy were sampled in the Skookumchuck River (Washington) for comparison. A variety of bacteria were isolated from these populations, and most notably, Acinetobacter spp. were identified from 82% of moribund individuals of Gonidea angulata in the Owyhee River. Future work evaluating whether Acinetobacter spp. are pathogenic to freshwater mussels could be valuable in unraveling the factors associated with these enigmatic mortality events.
