Despite growing interest in salespeople’s social media use, the role of customers in motivating and shaping such use has received limited scholarly attention. Moreover, little is known about whether—and how—social media use enhances salespeople’s effectiveness in managing service recovery situations. Using the conservation of resources theory and analyzing matched survey responses from B2B salespeople and their managers, we find that while customer interest in digital technology has a curvilinear (inverted U-shape) relationship with salesperson social media use, this relationship decreases at higher levels of job engagement, indicating that salespeople with high job engagement have greater resources to manage the stress caused by customer interest in digital technology. Moreover, social media use improves manager-rated salesperson service recovery performance. The study offers significant implications for both theory and practice.
Construction remains one of the most hazardous global industries, with worker fatalities occurring approximately every 99 min. However, safety is intrinsically linked to broader project performance; a truly safe construction site is hazard free, organized, and efficient, thereby minimizing waste and resource depletion. In response, a growing body of research has explored the use of advanced technologies, such as machine learning, robotics, wearable, and immersive visualization, to synergize safety improvements with sustainable building practices. In this article, we systematically review 165 peer-reviewed articles in the era of artificial intelligence (AI) that capture how technologies have evolved to address the dual imperatives of safety and sustainability in response to technology-driven transformation. To analyze this inflection, the article develops a four-domain taxonomy spanning AI, visualization, surveillance, navigation and collaboration, and wearable technology each mapped against both earlier and recent research studies. Crucially, we highlight emerging dual-utility applications, such as the use of "green digital twins" for real-time lighting optimization and UAVs for building envelope energy auditing. By mapping this transition, this article provides a grounded perspective on current capabilities, identifies research practice gaps, and supports informed decision-making for the implementation of future-integrated safety and sustainability technologies. The insights derived are aimed at supporting researchers, technology developers, and industry professionals to guide future integration of advanced, sustainable construction safety practices. Our review identifies recurring themes in the recent studies, including the integration of real-time sensing, multimodal data fusion, and user-centered system design. It also highlights unresolved challenges related to cross-project generalizability and long-term field adoption. By offering this structured analysis, the review aims to contribute a domain-wise benchmark of progress, capturing the recent technological inflection in construction safety and sustainability, and outlining future opportunities to support researchers, technology developers, and industry professionals.
Human-modified landscapes introduce novel and challenging environments that can drive rapid shifts in species behavior. Woodland salamanders (genus Plethodon) represent a key group to investigate the effects of human disturbance as they play critical roles in forest ecosystem function yet are highly sensitive to environmental change. Here, we examined behavioral responses of two closely related species, the Eastern Red-Backed Salamander (Plethodon cinereus) and the Northern Ravine Salamander (Plethodon electromorphus), to urban environmental features. Specifically, we tested salamander boldness toward concrete substrates (mimicking roads and walkways) and neophobic responses to common anthropogenic litter items that can be found in forest patches near urban areas. We predicted both species would avoid these novel features, but that P. cinereus would be more bold given its previously documented territorial and aggressive tendencies. We quantified three exploratory behaviors: time spent moving in the open, hiding, and thigmotaxis (wall-hugging behavior) but found evidence that only P. electromorphus increased thigmotaxis on the novel substrate. Both species exhibited neophobic responses to anthropogenic litter objects. Our results suggest that these novel urban features can alter the typical behaviors of these common salamander species. Future work should assess whether such avoidance behaviors reduce opportunities for dispersal, foraging, or mating, which may influence population persistence in urbanized landscapes.
Magnetic cellulose nanocrystal (MCNC) nanocomposites are promising sustainable and biocompatible platforms for magnetic hyperthermia; however, the molecular mechanisms governing Fe3O4 adsorption and deposition onto CNCs remain poorly understood. Here, sulfated (S-CNC) and TEMPO-oxidized CNCs (T-CNC) were used to prepare nanocomposites at 1:2 and 1:4 CNC:Fe3O4 mass ratios, enabling a systematic evaluation of how surface chemistry and nanoparticle loading dictate interfacial interactions and magneto-colloidal behavior. Bare magnetite nanoparticles were 21 ± 5 nm by TEM but grew to 144 ± 18 in the DLS measurement at pH 7. The S-CNC nanocomposites had hydrodynamic sizes between 144 and 210 nm, not much larger than the 140 nm long CNC rods, suggesting an enhanced dispersion stability compared to Fe3O4 alone. X-ray photoelectron spectroscopy combined with density functional theory revealed that -OH and -COOH groups drive electrostatic adsorption with charge transfer from Fe3O4 to the CNC surface, while T-CNCs showed more favorable adsorption energies and evidence of covalent Fe-O bonding. Vibrating sample magnetometry demonstrated superparamagnetic behavior for all samples, with S-CNC/Fe3O4 1:4 and 1:2 displaying saturation magnetizations of 78 and 77 emu/g-Fe3O4, close to the 83 emu/g of bare magnetite. The T-CNC composites showed lower (60 and 66 emu/g-Fe3O4) saturation magnetizations. Zero-field-cooled/field-cooled measurements resulted in a blocking temperature of 112 K for all samples, except T-CNC/Fe3O4 1:2 (100 K). Magnetic hyperthermia studies revealed that specific absorption rate (SAR) increased with field strength and Fe3O4 content; however, S-CNC/Fe3O4 (1:2) achieved the highest intrinsic SAR per gram of Fe3O4 (649 W/g-Fe3O4) likely due to its anisotropy and fast magnetic relaxation. Cytotoxicity assays confirmed that all nanocomposites were nontoxic toward mammalian cells. These results establish quantitative structure-property relationships between CNC surface chemistry, interfacial bonding mechanisms, and magnetic heating performance, providing a foundation for rational design of biocompatible magnetic nanocomposites for hyperthermia and related applications.
We examine how the processing of social information for identity-driven consumption choices is moderated by individual differences in the psychological management of multiple identities. We specifically show that consumers who experience their multiple identities as more incompatible-or low identity integrators-are less likely to conform to social information. Study 1 found evidence for this effect in a real-world consumption choice. Study 2 experimentally demonstrated that low identity integrators resisted social, but not technical, information. By manipulating identity integration experimentally, Study 3 found that identity integration directly affected preferences against socially vetted products above and beyond alternative individual difference factors. Suggesting that nonconformity to social information may serve self-protective motives, Study 4 found correlational evidence that low identity integrators tend to be especially concerned about the preferences of others when making their own consumption choices. Study 5 experimentally showed that low identity integrators tend to resist conforming to others' preferences only for products that signal identity but not for identity-irrelevant products, further suggesting that low identity integrators may counter social information to protect the self.
