Sustainable product attributes and firm performance: The moderating role of marketing resource intensity
Authors: Ullah Zeeshan 
Published: July 2021

AbstractThis paper aims to study the performance implications of sustainable product attributes (SPA) of US manufacturing firms. Specifically, it analyzes the influence of aggregate and disaggregated SPA on firm profitability. The study further explores the moderating influence of marketing resource intensity on aggregate and disaggregated SPA and firm profitability relationships. The fixed‐effect regression analysis of 433 US manufacturing firms' panel dataset reveals that aggregate and disaggregated SPA positively influence the firm profitability. The moderation analysis also confirms the positive influence of marketing resource intensity on aggregate and disaggregated SPA and firm profitability relationship. The current paper contributes to the triple‐bottom‐line and theory‐of‐the‐firm literature streams by empirically studying the influence of aggregate and disaggregated SPA on firm profitability. Furthermore, this study uses the resource‐based view to complement theory‐of‐the‐firm model of SPA and empirically study the moderating role of marketing resource intensity between aggregate and disaggregated SPA and firm profitability. Finally, the findings inform the managers of the increased firm profitability by aggregate and disaggregated SPA, and the pivotal role of marketing resource intensity in strengthening the positive influence of aggregate and disaggregated SPA on US manufacturing firms' profitability.
Probing the Role of Chirality in Phospholipid Membranes

Published: July 2021

AbstractNucleotides, amino acids, sugars, and lipids are almost ubiquitously homochiral within individual cells on Earth. While oligonucleotides and proteins exist as one natural chirality throughout the tree of life, two stereoisomers of phospholipids have separately emerged in archaea and bacteria, an evolutionary divergence known as “the lipid divide”. Within this review, we focus on the emergence of phospholipid homochirality and compare the stability of synthetic homochiral and heterochiral membranes in vitro. We discuss chemical probes designed to study the stereospecific interactions of lipid membranes in vitro. Overall, we aim to highlight studies that help elucidate the determinants of stereospecific interactions between lipids, peptides, and small molecule ligands. Continued work in understanding the drivers of favorable interactions between chiral molecules and biological membranes will lead to the design of increasingly selective chemical tools for bioorthogonal labeling of lipid membranes and safer membrane‐associating pharmaceuticals.

Published: July 2021

AbstractThe extrusion of dendrites and gas bubbles can lead to the appearance of dead lithium, which seriously reduces the coulomb efficiency, hindering the rapid development of high‐energy batteries. Therefore, it is very important to study the internal mechanism of the interaction between lithium dendrites and gas bubbles during electrochemical processes. In this paper, we have designed and developed a special in situ observation device for investigating the dendrite behavior. We also modified the phase‐field model to study the growth of lithium dendrites on the electrode with bubbles. The cantilever beam theory was applied to study the interaction between lithium dendrites and gas bubbles. The observed effects comprise the coalescence of gas bubbles, changing of lithium‐ion transport path on graphite electrode surface near the gas bubble, and bending of dendrites in front of the bubble. The local variation in the lithiation speed can be attributed to the insulating properties of the gas bubbles. Phase‐field simulation results of the interaction between dendrites and gas bubbles were consistent with the experimental results. A deeper insight into the gas‐bubble behaviors during dendrite growth with the presented simulation and experiment techniques becomes possible, which could be helpful to choose an appropriate structural design for reducing bubbles and lithium dendrites.

AbstractReactions of Li+ [(η5‐C5H5)Re(NO)(PPh3)]− with 2‐ and 4‐chloroquinoline or 1‐chloroisoquinoline give the corresponding σ quinolinyl and isoquinolinyl complexes 3, 6, and 8. With 3 and 8 there is further protonation to yield HCl adducts, but additions of KH give the free bases. Treatment of 3 with HBF4⋅OEt2 or H(OEt2)2+ BArf− gives the quinolinium salts [(η5‐C5H5)Re(NO)(PPh3)(C(NH)C(CH)4C(CH)(CH))]+ X− (3‐H+ X−; X−=BF4−/BArf−, 94–98 %). Addition of CF3SO3CH3 to 3, 6, or 8 affords the corresponding N‐methyl quinolinium salts. In the case of [(η5‐C5H5)Re(NO)(PPh3)(C(NCH3)C(CH)4C(CH)(CH))]+ CF3SO3− (3‐CH3+ CF3SO3−), addition of CH3Li gives the dihydroquinolinium complex (SReRC,RReSC)‐[(η5‐C5H5)Re(NO)(PPh3)(C(NCH3)C(CH)4C(CHCH3)(CH2))]+ CF3SO3− ((SReRC,RReSC)‐5+ CF3SO3−, 76 %) in diastereomerically pure form. Crystal structures of 3‐H+ BArf−, 3‐CH3+ CF3SO3−, (SReRC, RReSC)‐5+ Cl−, and 6‐CH3+ CF3SO3− show that the quinolinium ligands adopt Re⋅⋅⋅C conformations that maximize overlap of their acceptor orbitals with the rhenium fragment HOMO, minimize steric interactions with the bulky PPh3 ligand, and promote various π interactions. NMR experiments establish the Brønsted basicity order 3>8>6, with Ka(BH+) values >10 orders of magnitude greater than the parent heterocycles, although they remain less active nucleophilic catalysts in the reactions tested. DFT calculations provide additional insights regarding Re⋅⋅⋅C bonding and conformations, basicities, and the stereochemistry of CH3Li addition.

Published: July 2021

SummaryDue to the new technologies of the Internet of Things (IoT), connected objects have become smart interactive devices. However, despite their imminent advantages, whether for the daily life of users or in professional contexts, and the various security solutions proposed in literature in particular, the security of IoT networks is still a paramount issue given to the amount of confidential data that circulates through these technologies. In other words, among the IoT protocols that suffer from security issues, routing protocol for low power and lossy networks (RPL) is considered to be one of the most widely used protocols in the deployment of constrained IoT networks with limited resources (storage and energy constraints for example). On this basis, this article investigates in the first part a security flaw in the RPL protocol by carrying out an attack against the rank value of the RPL in an IoT environment. In the second part, a mitigation scheme to avoid it using a trust threshold is proposed. The malicious behavior of the attack and the effectiveness of the proposed scheme were assessed by detailed simulations using the Cooja simulator, in terms of successful detection rate, average network hops and global energy consumption. To conclude, a fair comparison between the different simulation results has been adopted using the Friedman statistical test, and a discussion has been presented with some future works concerning security against rank attack.
Dynamics of microglia and dendritic spines in early adolescent cortex after developmental alcohol exposure

Published: July 2021

AbstractFetal alcohol spectrum disorder patients suffer from many cognitive disabilities. These include impaired auditory, visual, and tactile sensory information processing, making it more difficult for these patients to learn to navigate social scenarios. Rodent studies have shown that alcohol exposure during the brain growth spurt (BGS) can lead to acute neuronal apoptosis and an immunological response by microglia in the somatosensory cortex. Since microglia have critical physiological functions, including the support of excitatory synapse remodeling via interactions with dendritic spines, we sought to understand whether BGS alcohol exposure has long‐term effects on microglial or dendritic spine dynamics. Using in vivo two‐photon microscopy in 4–5 week old mice, we evaluated microglial functions such as process motility, the response to tissue injury, and the dynamics of physical interactions between microglial processes and dendritic spines. We also investigated potential differences in the morphology, density, or dynamics of dendritic spines in layer I/II primary sensory cortex of control and BGS alcohol exposed mice. We found that microglial process motility and contact with dendritic spines were not altered after BGS alcohol exposure. While the response of microglial processes toward tissue injury was not significantly altered by prior alcohol exposure, there was a trend suggesting that alcohol early in life may prime microglia to respond more quickly to secondary injury. Spine density, morphology, stability, and remodeling over time were not perturbed after BGS alcohol exposure. We demonstrate that after BGS alcohol exposure, the physiological functions of microglia and excitatory neurons remain intact in early adolescence.
Optimal foraging by a large ungulate in an extreme environment: Wild mountain reindeer select snow‐free feeding habitats in winter

Published: July 2021

AbstractOptimal foraging models predict that individual animals will optimize net energy gain by intensifying forage activity and/or reducing forage energy cost. Then, the free distribution model predicts an animal's distribution in a patchy landscape will match the distribution of the resources. If not modified by other factors, such patterns may be expected to be particularly explicit in variable and extreme, forage‐limited, and patchy environments, notably alpine and Arctic environments during winter. The large ungulate wild mountain reindeer (Rangifer tarandus tarandus) surviving in such environments is used as a model during the forage‐limited winter season. The largest wild reindeer area in Western Europe (Hardangervidda, 8130 km2) is actively managed to sustain 10,000–12,000 wild reindeer. Since 2001, 104 different individuals have been GPS‐tracked at 3‐hr intervals. In winter, mountain reindeer may either choose to seek out and forage in patchy snow‐free habitats, typically on top of wind‐blown ridges, or use energy‐demanding digging through the snow to reach ground forage (cratering). We use late April satellite data from Landsat 5 and 8 (30 × 30 m), airborne laser scanning subsampling (processed to 1 × 1 m grid), and topographic information (1 m resolution) derived from digital aerial photographs (0.25 × 0.25 m resolution) to delineate snow‐free patches, constituting less than 694 km2. By overlaying recorded wild reindeer GPS positions winters 2001–2017 (188,942 positions), we document a strong positive selection for snow‐free patches, which were used about four times more frequently than expected from a “random walk” model. On a daily basis, the preference for snow‐free areas was slightly stronger in the evenings. In the sustainable management of wild mountain reindeer, the area of snow‐free patches is an important predictor of winter forage availability and important winter source areas. It may be derived from remote sensing data.
Environmental variability affects optimal trade‐offs in ecological immunology
Authors: Kirk Devin , Greischar Megan , Mideo Nicole , Krkošek Martin 
Published: July 2021

AbstractThe costs of mounting and maintaining an immune response lead to trade‐offs with investment in (or maintenance of) other organ systems or functions such as reproduction, as has been observed in several taxa, including birds, insects, and mammals. Given these trade‐offs, optimal strategies can be affected by biotic and abiotic conditions; however, how these trade‐offs are affected by environmental variability remains unclear. Using a deterministic within‐host model of disease dynamics, we analyzed the effect of environmental variability (here, the coefficient of variation in the host’s background survival distribution) on the optimal resolution to a trade‐off between investment in reproduction and the immune system. We found that higher variability led to increased investment in the immune system at the cost of decreased early‐life reproduction when the immune investment strategy was assumed to be constant through life. Since we manipulated the distribution of lifespans while keeping the mean lifespan constant, our results suggest that even the small probability of living far past the mean lifespan for individuals in highly variable environments has a large effect on the optimal investment strategy. When immune investment was able to change over the age of the organism, the optimal investment strategies were again contingent on the level of environmental variability experienced by individuals. Our results support and extend previous work on optimal life‐history theory in variable environments by showing that in the context of ecological immunology, the most fit individuals in constant environments are not the most fit individuals in variable environments. The effects of environmental variability on optimal immune investment are likely to have consequences for other aspects of infectious disease such as transmission dynamics, virulence evolution, and the likelihood of epidemics occurring.
Triacylglycerols and Polar Lipids in Cow and Goat Milk are Differentially Affected by Various Lipid Supplemented Diets

Published: July 2021

AbstractThis study characterizes milk triacylglycerol (TAG) and polar lipid (PL) fractions from cows and goats fed various lipid supplements modulating milk fat content. Twelve Holstein cows and 12 Alpine goats, at 86 ± 24.9 and 61 ± 1.8 days in milk, respectively, are allocated to one of 4 groups to receive diets supplemented with either corn oil [5% dry matter intake (DMI)] plus wheat starch (COS), marine algae powder (MAP; 1.5% DMI) or hydrogenated palm oil (HPO; 3% DMI), or a no‐added‐lipid control diet (CTL), according to a 4 × 4 Latin square design with 28 d experimental periods. Milk TAG and PL contents are determined by liquid chromatography‐mass spectrometry (LC‐MS). Multivariate analysis and ANOVA demonstrate major between‐species differences in diet effects. In cows, COS specifically increases TAG 54:3 and 54:4 associated with milk fat depression (MFD), and increases the sum of phosphatidylcholines (PC) and phosphatidylinositols (PI). In addition to causing a MFD, MAP diet increases long‐chain polyunsaturated TAG in both species, with higher magnitude in cows than in goats, and decreases the sum of PI in goats. HPO increases TAG 52:1 and the sum of PI in cows, but not in goats.Practical applications: Feed strategies can quickly and efficiently modulate the ruminant milk fat production and composition to improve nutritional quality for consumers. Certain starch‐rich diets supplemented with polyunsaturated fatty acids (PUFA)‐rich vegetable oils and diets supplemented with marine products (long‐chain PUFA) reduce milk fat secretion and modify the milk fatty acid (FA) profile in cows, but not—or less so—in goats. Advanced analysis of both the TAG and PL fractions of milk fat is required to unravel these differences in lipid metabolism between cows and goats fed various lipid‐supplemented diets. This study brings new insight on using nutritional strategies to control milk lipid composition according to ruminant species.

Published: July 2021

AbstractIt is the most efficient way to solve the sluggish kinetics of anodic oxygen evolution reaction during water electrolysis and realize rapid high‐purity hydrogen production by designing high performance oxygen evolution reaction (OER) catalysts. Herein, we have designed a series of PdRu nanoparticles‐modified carbon nanotubes (PdRu/CNTs) by rapid solvent‐free microwave‐assisted method. In this process, CNTs were chosen as the substrate because of its highly stable structure and fast electron transfer. What's more, Pd and Ru have formed a PdRu alloy and occurred partial oxidation based on the analysis of X‐ray diffraction and X‐ray photoelectron spectra spectrums. Through the regulation of composition, Pd69Ru31/CNTs exhibit excellent OER performance in 0.1 M HClO4 with a lowest overpotential of 225 mV at the current density of 10 mA cm−2. In the meanwhile, the current density of Pd69Ru31/CNTs was almost unchanged after 10 h i‐t test, and the overpotential only occurred to 10 mV positive shift after 5000 testing cycles. This work provides a feasible way to design high performance Pd‐based OER catalysts.

AbstractA new Cd‐Eu coordination polymer (CP) with open‐chain ether Schiff base ligand bis(3‐methoxysalicylidene)‐3‐oxapentane‐1,5‐diamine (H2L) and 4,4′‐bipyridine (bipy), with composition [CdEuL(bipy)(NO3)3]n, has been synthesized by interfacial diffusion method and further performed structural characterization. The structure analysis revealed that Cd‐Eu CP is an infinite one‐dimensional zigzag coordination polymer formed by CdEuL secondary units through symmetrical coordination bridging bipy. Luminescence property of the Cd‐Eu CP in solid state was also studied. It has been found that the emission spectra of the Cd‐Eu CP exhibit corresponding Eu(III) ion characteristic emission peaks. Antioxidation activities of the ligand and the Cd‐Eu CP were also studied, showing that the antioxidant activities of the Cd‐Eu CP were better than that of H2L. All provide an irreplaceable reference for the study of the properties of one‐dimensional chain d–f coordination polymers.

We prove that there is no such graph on the projective plane is the unique such graph on the Klein bottle and is the unique such graph on the torus . In contrast to this for each we construct an infinite family of such graphs on the orientable surface of genus , that are edges short of a triangulation.
