“…In this regard, the value of a variable of interest in each region ( i ) is associated with the value of the same variable in the neighboring regions ( j ) . We first used Moran’s I to check for spatial autocorrelation ( 41 , 42 ). Then, we developed both ordinary least squares and spatial regression models to assess the equity impact of transit accessibility.…”

Addressing social equity in public transportation remains a key challenge for many cities and planning organizations. In this study, we examined social equity dimensions of accessibility to light rail transit (LRT) stations in Salt Lake County, U.S., by employing two novel methods. First, we used the two-step floating catchment area (2SFCA) method to examine the interactions between the demand and supply of the public transit service. Second, we developed geospatial models to account for spatial bias in transit equity analysis. Results showed little evidence of inequitable access to LRT stations in Salt Lake County. The accessibility to LRT stations appeared to be generally higher in the downtown and transit catchment areas with a higher concentration of low-income and ethnic minority populations. Furthermore, we found statistically significant associations between higher transit accessibility and households which are not homeowners, and/or do not own a private motor vehicle. Our findings suggest that transit investments in Salt Lake County could leverage substantial transportation accessibility opportunities to achieve an equitable and sustainable future.

“…However, under the high fishing pressure of the early 2000s, particularly since 2003, the landing continued to decrease until 2009 (Figure 1), and anchovy spawning stock biomass (SSB) in the Yellow Sea during the early 2000s declined significantly from 1.3 × 10 6 tons to 0.2 × 10 6 tons, as estimated through acoustic methods [15,18,19]. There is also a phenomenon of catch composition characterized by miniaturization, early sexual maturity, and decreasing catch per unit effort (CPUE) [16,20,21]. In recent years, the anchovy landings gradually increased until 2015, followed by a subsequent decrease.…”

Japanese anchovy (Engraulis japonicus) is a small pelagic fish with commercial and ecological importance. In spite of its importance, in recent years, specific research on anchovy in the Shandong Peninsula area has been relatively scarce and outdated. This study aims to estimate the age and growth characteristics of anchovy through year-round seasonal sampling from 2016 to 2017, utilizing length–frequency and otolith microstructure analysis. The higher coastal abundance and larger size observed in the spring and summer suggest a potential peak spawning period for anchovies dominated by larger-sized individuals. Based on otolith analysis, anchovies range in age from 0 to 4 years, with a limited presence at age 0 and dominance in the age-1 group. The length–weight relationship (LWR) equation shows hyper-allometric growth for each season, with a mean relative condition factor (Kn) of 1.025 ± 0.005, indicating good health. Additionally, the von Bertalanffy growth equation of can be expressed as Lt = 154.40 [1 − e−0.604 (t + 0.965)], suggesting a medium growth rate (K = 0.604). These findings contribute to the understanding of anchovy age and growth patterns, emphasizing the continuous need for research and monitoring to support rational and sustainable fisheries management and conservation efforts.
