This study investigates how the structural mix of USA regional economies affects their volatility of economic growth. Four exogenous sectors are chosen for this investigation: Federal Government, construction, manufacturing, and tourism. Perhaps unsurprisingly, evidence suggests that a larger share of Federal Government employment in an economy reduces the variability of overall employment growth, while a larger share of construction activity elevates it. More telling is a finding that, recently, manufacturing has not contributed as much to such variability, and that a larger tourism presence increases it. The increasing integration of technology in tourism offers significant opportunities for a network approach and innovation in regional development.

In France, the regional airport’s demand for services is facing challenges due to the continuous expansion of the high-speed train, high-speed line, and highway networks. This study focuses on the viability of regional airports in France through technical efficiency using data envelopment, principle component analysis, Malmquist productivity index, and regression analysis using bootstrapping. To face the current competitive environment, the regional airports in France adopted strategies, such as the construction of low-cost carrier (LCC)-dedicated terminals (LCCTs) with lower expenses to attract more LCCs, increasing non-aeronautical revenue, and hosting regional hubs of LCCs. This is the first study that analyzes all of the French regional airports. The findings indicate that the existence of LCCTs positively affects technical efficiency on the airport’s performance, and share of LCCs at a regional airport leads to neither the efficiency nor the profit level.

Previous research evidence showed deficient physical activity (PA) and physical fitness (PF) performance levels among high school students. Personal goal orientations motivate their behavior; therefore, it is essential to discover high school students’ goal orientations in PA and PF. Guided by the latest 3 × 2 achievement goal model, we examined the influence of six goal orientations on PA and PF in high school students. A total of 792 high school students in China (54.5% girls; Mage = 16.93 ± 0.82) completed validated measurements assessing 3 × 2 goal orientations for PA and PF. Stepwise multiple regression analyses were used to analyze whether 3 × 2 achievement goal orientations significantly influenced the study variables. Other-approach, self-approach, and task-avoidance goals significantly predicted PA, and the 50-meter dash was predicted by other-approach and self-avoidance goals. The self-approach goal was the only significant predictor of the standing long jump. In conclusion, fostering self- and other-approach-oriented environments with developmentally appropriate content in physical education may have implications for enhancing high school students’ PA and PF.

Phosphonic acid functionalization of gellan gum and chitosan biopolymers was successfully performed. In the first step, the sorption was investigated using La(III) ions before testing for the recovery of rare earth elements (REEs) from pretreated industrial acidic leachate. The sorbent was characterized by Fourier-transform infrared (FTIR), scanning electron microscopy with energy dispersive X-ray analysis (SEM-EDX), thermogravimetric analysis (TGA), Brunauer–Emmett–Teller (BET), and pH of zero charge (pHPZC) determination. FTIR and EDX results show efficient grafting of phosphoryl groups. The sorption was determined for the crude materials before functionalization (PGEG) and after phosphorylation (TBP-PGEG). More efficient sorption was seen for phosphorylated sorbent than for the crude composite. The sorption capacity is 0.226 mmol La g−1 for the PGEG while the value is 0.78 mmol La g−1 for the TBP-PGEG. We infer that phosphonate groups participate in the sorption. The most effective sorption is at pH = 4. The kinetic behavior was described using pseudo first-order equations (PFORE), pseudo second-order equations (PSORE), and resistance to intraparticle diffusion (RIDE). The sorption isotherms can be better represented by Langmuir and Sips equations than by the Freundlich equation. The sorbent shows high stability performance during reuse cycles with a limit on the decrease in the sorption performances and stability in the desorption performances. We have thus developed a good tool for the recovery of REEs with a selectivity higher than that of the non-functionalized components.

The complex interaction between social, economic, and environmental processes coupled with transformations of the landscape primarily driven by urbanization have impacts on the access, availability, and distribution, of food. This has resulted in a global micronutrient deficiency and hunger. Given rapid urbanization and population growth, a more sustainable food system is necessary to feed more urban populations and provide adequate nutrition, especially in developing countries. Existing frameworks for modelling urban-environment interactions contain components related to food security, however, lack the specificity needed to evaluate the effects of land use decisions and agricultural production strategies on the health of local populations measured through metrics such as nutritional output. The research presented here proposes an urban nutrition (UN) extension to the previously published urban ecological economic system by developing a focused component that simulates scenarios of different degrees of urbanization and agricultural production techniques to improve the nutritional output of agricultural land, while considering the conservation of soil. This simulation approach was subsequently applied to the Toluca Metropolitan Zone, Mexico. Results showed that nutritional output would greatly increase when adding a variety of crops, even in scenarios where agricultural land is limited. The proposed extension can be used by decision makers worldwide to evaluate how landscape configurations and agricultural production systems affect the nutritional needs of the local population while fostering sustainable practices.

The secondary luxury market is a recent phenomenon attributed to changing consumer beliefs that influence their consumption process. The purpose of this study was to explain consumption behaviors of secondary luxury consumers by investigating secondary consumer beliefs and purchase intention, specifically in the context of online shopping. An online survey was created in Qualtrics to collect data. After a preliminary analysis, structural equation modeling was used to conduct a confirmatory factory analysis and to test the hypothesized relationships. The findings revealed that all consumer beliefs, including environmental, frugality, online retailing, and fashion consciousness, positively influenced consumers’ attitudes and subsequent purchase intention for second-hand luxury items from online secondary luxury retailers. This study added to the literature by utilizing the Theory of Planned Behavior framework and incorporating the secondary luxury consumer beliefs. Ultimately, the researchers were able to better understand this online secondary luxury consumer and what influences the consumer to purchase secondary luxury goods from online retailers such as The RealReal.

Information about the factors associated with conservation participation by local communities is important to garner support and involvement within a natural protected area. This research examined how residents’ natural resource dependency and other social, economic, and access-related variables predict conservation participation. Data were collected based on a stratified random sampling of households from Gaurishankar Conservation Area Project (GCAP)—a newly designated mountainous protected area in Nepal. Analysis was conducted via an ordered logistic regression model. Higher levels of participation were observed among households that comprised of a larger family size, belonged to a higher caste/ethnicity, resided in higher elevations, and noted frequent visits and interactions with park management staff. However, natural resources dependency (i.e., income and fuelwood fodder) lacked a statistically significant relationship with conservation participation. Similarly, the economic dimension (i.e., land holdings and total livestock unit) was not a significant predictor of participation. Overall, key findings suggest that conservation participation at GCAP needs to be improved with multiple outreach activities, especially to resource-dependent households. More specifically, it is important to ensure equitable access so that locals can participate in programs that provide alternative resource use options, skills development, and trainings for income generation activities.

Tourism has been recognized as an important economic sector, requiring a high degree of involvement from the entrepreneurial sector to diversify tourism products and services to meet increasing demand. Tourism is often considered a tool for economic development and a strategy to improve the livelihoods of rural citizens. Specifically, nature-based tourism, such as wildlife tourism, is growing faster than tourism in general, providing a myriad of opportunities for small-scale entrepreneurial engagement. However, several obstacles exist for these small-scale tourism enterprises, such as a lack of social capital. This study examined a network of wildlife tourism microentrepreneurs for bonding and bridging forms of social capital using a social network analysis approach, where bonding and bridging social capital have their own interpretation. Thirty-seven in-person interviews were conducted with wildlife tourism microentrepreneurs from North Carolina’s Pamlico Sound Region. The study revealed that microentrepreneurs interacted with each other in a bridging network structure. The ability to reciprocate with other members of the network was essential for business success. The results identified four key bridging ties connecting potential sub-groups in the network, connected to each other in a redundant fashion. We concluded that the formation of a bridging network structure was a function of entrepreneurial phenomena that may not promote a highly trusted, well-connected network. The findings and implications are further discussed in the paper.
