Employment Stability and the Role of Sectoral Dominance in Rural Economies
Authors: Fawson Christopher , Thilmany Dawn , Keith John E. 
Published: July 2006

AbstractRural development has received renewed attention, particularly in the West, where there are opportunities for enhancing tourism in communities once reliant on extractive resources. The historical focus of rural development has been on economic growth, with little concern about the sustainability or socioeconomic impacts of such growth. This study analyzes and discusses the employment dynamics of rural economies with varying employment bases to illustrate some possible impacts of targeting specific employment sectors as part of a rural economic development strategy. The empirical research focuses on the rural counties of Utah, where the trade and service sectors associated with increased tourism and retirement communities have been rapidly expanding throughout the past two decades.
Better Confidence Intervals: The Double Bootstrap with No Pivot
Authors: Letson David , McCullough B.D. 
Published: July 2006

AbstractThe double bootstrap is an important advance in confidence interval generation because it converges faster than the already popular single bootstrap. Yet the usual double bootstrap requires a stable pivot that is not always available, e.g., when estimating flexibilities or substitution elasticities. A recently developed double bootstrap does not require a pivot. A Monte Carlo analysis with the Waugh data finds the double bootstrap achieves nominal coverage whereas the single bootstrap does not. A useful artifice dramatically decreases the computational time of the double bootstrap.
Mother's Nutrition Knowledge and Children's Dietary Intakes
Authors: Variyam Jayachandran N. , Blaylock James , Lin Biing‐Hwan , Ralston Katherine , Smallwood David 
Published: July 2006

AbstractThis article uses U.S. food consumption data to examine the effect of maternal nutrition knowledge on the dietary intakes of children between two and seventeen years of age. Results show that maternal knowledge influences children's diets and that such influence decreases as children grow older. Nutrition knowledge acts as a pathway through which maternal education influences children's diets. This finding supports the hypothesis that education affects health‐related choices by raising the allocative efficiency of health input use. The results suggest that nutrition education may be more effective if targeted both toward mothers with young children and directly toward school‐age children.
Some Productivity‐Increasing and Quality‐Changing Technology for the Soybean Complex: Market and Welfare Effects
Authors: Gallagher Paul W. 
Published: July 2006

AbstractSimulations suggest that soybeans with less protein and more oil would alter quality and change quantities on the market. Substitution toward other protein feeds, like fishmeal, would mitigate the benefits from restricted soymeal supply. Thus, there would not be a net welfare gain for the United States, only a redistribution of benefits. But a joint yield increase and composition change would benefit the United States, mainly because livestock producers would pay lower feed prices. Also, industrial processing of soybean oil would become competitive. Hence, soybean research should pursue yield increases by allowing protein reductions.
Testing Homogeneity in the Linearized Almost Ideal Demand System
Authors: Buse Adolf 
Published: July 2006

AbstractThe behavior of exact tests for homogeneity (F and Hotelling T2) is compared with size‐adjusted LR tests in the linearized AIDS model with different approximating price indexes (Stone, Paasche, Laspeyres). The Monte Carlo evidence shows that test size distortions are sensitive to the correlation structure of prices, the time‐series properties of the data, and the choice of price index. None of the results explains the persistent over‐rejection of homogeneity in applied work.
Bipartite containment control of nonlinear multi‐agent systems with unknown inputs and state constraints
Authors: Zhao Younan , Zhu Fanglai 
Published: March 2024

SummaryThis article addresses the issue of bipartite containment tracking for nonlinear strict feedback multi‐agent systems (MASs) with disturbances and measurement uncertainties. To provides a better performance against strong disturbance, a coordination transformation is applied such that all the nonlinear functions, controller disturbances and measurement uncertainties are lumped into a single disturbance signal in the last state equation. Then, the lumped disturbance is compensated through a novel disturbance rebuilding method. Moreover, in order to get better control performance, state constraints are also considered through a nonlinear transformation function (NTF). Different from traditional methods dealing with the state constraint problems, the NTF method can avoid using any discontinuous Lyapunov function. Finally, an adaptive finite‐time distributed controller is established via the disturbance estimates, backstepping technique and fuzzy logic system (FLS). The performance of the controller is illustrated by a simulation example in which the bipartite containment formation of followers is realized in a practical finite time.

AbstractConventional therapies for inflammatory bowel diseases are mainly based on systemic treatments which cause side effects and toxicity over long‐term administration. Nanoparticles appear as a valid alternative to allow a preferential accumulation in inflamed tissues following oral administration while reducing systemic drug exposure. To increase their residence time in the inflamed intestine, the nanoparticles are here associated with a hydrogel matrix. A bioadhesive peptide‐based hydrogel is mixed with nanoemulsions, creating a hybrid lipid‐polymer nanocomposite. Mucopenetrating nanoemulsions of 100 nm are embedded in a scaffold constituted of the self‐assembling peptide hydrogel product PuraStat. The nanocomposite is fully characterized to study the impact of lipid particles in the hydrogel structure. Rheological measurements and circular dichroism analyses are performed to investigate the system's microstructure and physical properties. Biodistribution studies demonstrate that the nanocomposite acts as a depot in the stomach and facilitates the slow release of the nanoemulsions in the intestine. Efficacy studies upon oral administration of the drug‐loaded system show the improvement of the disease score in a mouse model of intestinal inflammation.

Published: March 2024

AbstractBiomedical alloys are paramount materials in biomedical applications, particularly in crafting biological artificial replacements. In traditional biomedical alloys, a significant challenge is simultaneously achieving an ultra‐low Young's modulus, excellent biocompatibility, and acceptable ductility. A multi‐component body‐centered cubic (BCC) biomedical high‐entropy alloy (Bio‐HEA), which is composed of non‐toxic elements, is noteworthy for its outstanding biocompatibility and compositional tuning capabilities. Nevertheless, the aforementioned challenges still remain. Here, a method to achieve a single phase with the lowest Young's modulus among the constituent phases by precisely tuning the stability of the BCC phase in the Bio‐HEA, is proposed. The subtle tuning of the BCC phase stability also enables the induction of stress‐induced martensite transformation with extremely low trigger stress. The transformation‐induced plasticity and work hardening capacity are achieved via the stress‐induced martensite transformation. Additionally, the hierarchical stress‐induced martensite twin structure and crystalline‐to‐amorphous phase transformation provide robust toughening mechanisms in the Bio‐HEA. The cytotoxicity test confirms that this Bio‐HEA exhibits excellent biocompatibility without cytotoxicity. In conclusion, this study provides new insights into the development of biomedical alloys with a combination of ultra‐low Young's modulus, excellent biocompatibility, and decent ductility.

AbstractA variety of functionalized 3‐arylazoindoles were prepared in good to excellent yields through an iron(III)‐catalyzed C−H azolation of 2‐substituted indoles with arylhydrazines under mild reaction conditions. The reaction underwent an initial TBN‐mediated nitrosation, 1,5‐hydrogen migration, intramolecular condensation, and 1,5‐hydrogen migration over four steps in one pot. A paracyclophane‐derived 3‐phenylazoindole could be prepared in 25% yield over three steps and some prepared 3‐arylazoindoles showed a different fluorescence emission wavelength and existed obvious pH conditions response. The present method highlights broad substrate scope of easily available starting materials, wide range of functional group compatibility, gram scalable preparations, high atom economy, avoidance of unstable and explosive azolation reagents, and simple purification operations by extraction, washing, and recrystallization without flash column chromatography.

AbstractWithin the burgeoning field of electronic materials, B−N Lewis acid‐base pairs, distinguished by their partial charge distribution across boron and nitrogen centers, represent an underexplored class with significant potential. These materials exhibit inherent dipoles and are excellent candidates for ferroelectricity. However, the challenge lies in achieving the optimal combination of hard‐soft acid‐base pairs to yield B−N adducts with stable dipoles. Herein, we present an enantiomeric pair of B−N adducts [R/SC6H5CH(CH3)NH2BF3] (R/SMBA‐BF3) crystallizing in the polar monoclinic P21 space group. The ferroelectric measurements on RMBA‐BF3 gave a rectangular P‐E hysteresis loop with a remnant polarization of 7.65 μC cm−2, a value that aligns with the polarization derived from the extensive density‐functional theory computations. The PFM studies on the drop‐casted film of RMBA‐BF3 further corroborate the existence of ferroelectric domains, displaying characteristic amplitude‐bias butterfly and phase‐bias hysteresis loops. The piezoelectric nature of the RMBA‐BF3 was confirmed by its direct piezoelectric coefficient (d33) value of 3.5 pC N−1 for its pellet. The piezoelectric energy harvesting applications on the sandwich devices fabricated from the as‐made crystals of RMBA‐BF3 gave an open circuit voltage (VPP) of 6.2 V. This work thus underscores the untapped potential of B−N adducts in the field of piezoelectric energy harvesting.

AbstractThe second near‐infrared (NIR‐II) theranostics offer new opportunities for precise disease phototheranostic due to the enhanced tissue penetration and higher maximum permissible exposure of NIR‐II light. However, traditional regimens lacking effective NIR‐II absorption and uncontrollable excited‐state energy decay pathways often result in insufficient theranostic outcomes. Herein a phototheranostic nano‐agent (PS‐1 NPs) based on azulenyl squaraine derivatives with a strong NIR‐II absorption band centered at 1092 nm is reported, allowing almost all absorbed excitation energy to dissipate through non‐radiative decay pathways, leading to high photothermal conversion efficiency (90.98 %) and strong photoacoustic response. Both in vitro and in vivo photoacoustic/photothermal therapy results demonstrate enhanced deep tissue cancer theranostic performance of PS‐1 NPs. Even in the 5 mm deep‐seated tumor model, PS‐1 NPs demonstrated a satisfactory anti‐tumor effect in photoacoustic imaging‐guided photothermal therapy. Moreover, for the human extracted tooth root canal infection model, the synergistic outcomes of the photothermal effect of PS‐1 NPs and 0.5 % NaClO solution resulted in therapeutic efficacy comparable to the clinical gold standard irrigation agent 5.25 % NaClO, opening up possibilities for the expansion of NIR‐II theranostic agents in oral medicine.

AbstractAs one of the self‐luminescence imaging approaches that require pre‐illumination instead of real‐time light excitation, afterglow luminescence imaging has attracted increasing enthusiasm to circumvent tissue autofluorescence. In this work, we developed organic afterglow luminescent nanoprobe (nanotorch), which could emit persistent luminescence more than 10 days upon single light excitation. More importantly, the nanotorch could be remote charged by 660 nm light in a non‐invasive manner, which showed great potential for real‐time tracing the location of macrophage cell‐based microrobots.

Published: March 2024

AbstractThe eusuchian crocodyliforms recorded in the Eocene levels of the Spanish Duero Basin belong to three lineages: Planocraniidae, with the species Duerosuchus piscator; Alligatoroidea, represented by several specimens of the genus Diplocynodon; and Crocodyloidea, which includes several specimens traditionally attributed to Asiatosuchus. The genus Asiatosuchus, established in 1940 based on a middle Eocene species from Mongolia, has subsequently served as a wastebasket taxon for Paleogene remains belonging to several species, not only from Asia but also belonging to the European and North American records. Many of these species are known by highly fragmentary remains, sharing the presence of characters such as a flat and triangular skull, and long symphyses in the lower jaw, recognized as characteristic for the crocodyloids. In addition to isolated cranial remains, among the material traditionally attributed to Asiatosuchus at the Duero Basin stands out a nearly complete skull and a left mandible, from the middle Eocene area of Casaseca de Campeán (Zamora Province). The present study analyses in detail these specimens, previously reported during the 1980s, but analyzed in a very preliminary way. They are included for the first time in a phylogenetic analysis to establish the systematic position of this Spanish form. The results confirm that it corresponds to a new species of basal crocodyloid, defined here as Asiatosuchus oenotriensis sp. nov.

AbstractThe changes in the East Asian polar‐front jet (EAPJ) and the East Asian subtropical jet (EASJ) profoundly impact the weather and climate in East Asia. However, the link between aerosols and the jet streams is still unclear. Here, we investigated the decadal co‐variation of aerosols and the East Asian jet streams in the boreal winter during the period of 1980–2019. In synch with a positive change in aerosol optical depth over East Asia, 300‐hPa winds show an equatorward shift of the land branch of the EASJ, and weakened EAPJ and oceanic branch of the EASJ. This can be linked to the enhanced meridional temperature gradient along 30°–50° N but weakened in northern regions and the decreasing synoptic‐scale transient eddy kinetic energy over subtropical Pacific. Relative importance estimation of aerosols and ocean signals emphasized the contributions of aerosols in jet variations. In turn, meteorological conditions related to jet streams also contribute to variations in aerosols, the decadal co‐variations are a result of their interactions, particularly for the oceanic branch of EASJ. The findings would be helpful in providing potential indicators of climate change.
The effect of maturity learn element in Enterprise risk management and corporate social responsibility on the level of digital transformation
Authors: Djakman Chaerul Djusman , Siregar Sylvia Veronica 
Published: March 2024

AbstractEnterprise Risk Management (ERM) has emerged as a response to globalization and regulatory pressure on firms to manage their risk comprehensively. CSR is related to corporate risk management, as by engaging in CSR activities firms can be more effective in managing stakeholder relationships. Extant studies rarely examine both issues to the level of digital transformation. In the coming years, the issue of digital transformation will have an even bigger impact on business models. The first step in the effective implementation of ERM is the ability of the organization to learn and understand the requirements of ERM implementation in its company. Thus, it is important to examine the effect of the maturity learn element in ERM and CSR as risk management on the level of digital transformation. In addition, this paper also examines the moderating role of CSR on the association between ERM and the level of digital transformation. Our samples consist of manufacturing companies of developed countries in the European Union (which consists of Italy, Spain, Belgium Switzerland, Germany, France, and UK). The paper found evidence that enterprise risk management has a positive significant effect on the level of digital transformation. The paper also found evidence that CSR has a direct effect on the level of digital transformation. However, the paper failed to provide supporting evidence on the moderating role of CSR on the association between ERM and the level of digital transformation.

Published: March 2024

AbstractThe pine cones (PC), spruce cones (SC) and fir cones (FC) were used for biocarbons preparation. Chemical activation with sodium hydroxide was applied to prepare activated biocarbons. All the materials under investigation were characterized by the N2 adsorption, scanning electron microscopy (SEM), elemental analysis (CHNS), infrared spectroscopy (ATR FT‐IR), and the Boehm's titration method. Moreover, pHpzc (the point of zero charge) was determined. It was shown that cones are a good, cheap precursor from which biocarbons with a developed porous structure, characterized by good adsorption properties, can be obtained. All the obtained adsorbents are characterized mainly by a microporous structure. Moreover, they contain both acidic and basic surface functional groups (acidic ones prevail over basic ones). The tested activated biocarbons have large specific surface area values ranging from 578 to 1182 m2 g−1. The efficacy of selected materials in the adsorption of an essential contaminant of increasing concern, tetracycline (TC), was investigated. The experimental data were described using the Langmuir and Freundlich adsorption isotherm models. The maximum adsorption capacity of the tested biocarbons ranges from 200 to 392 mg g−1. Thermodynamic studies proved that adsorption is a spontaneous and endothermic process. In summary, economical and environmentally friendly adsorbents were obtained.

AbstractFor its vital role in maintaining cellular activity and survival, mitochondrion is highly involved in various diseases, and several strategies to target mitochondria have been developed for specific imaging and treatment. Among these approaches, theranostic may realize both diagnosis and therapy with one integrated material, benefiting the simplification of treatment process and candidate drug evaluation. A variety of mitochondria‐targeting theranostic agents have been designed based on the differential structure and composition of mitochondria, which enable more precise localization within cellular mitochondria at disease sites, facilitating the unveiling of pathological information while concurrently performing therapeutic interventions. Here, progress of mitochondria‐targeting theranostic materials reported in recent years along with background information on mitochondria‐targeting and therapy have been briefly summarized, determining to deliver updated status and design ideas in this field to readers.
