Abstract

Given the concerns about urban mobility, traffic congestion, and greenhouse gas (GHG) emissions, extensive research has explored the relationship between the built environment and transit ridership. However, the nature of aggregation and the cross-sectional approach of the research rarely provide essential clues on the potential of a transit system as a sustainable mobility option. From the perspective of longitudinal sustainability, this paper develops regression models for rail transit stations in the Los Angeles Metro system. These models attempt to identify the socio-demographic characteristics and land use features influencing longitudinal transit ridership changes. Step-wise ordinary least square (OLS) regression models are used to identify factors that contribute to transit ridership changes. Those factors include the number of dwelling units, employment-oriented land uses such as office and commercial land uses, and land use balance. The models suggest a negative relationship between job and population balance with transit ridership change. They also raise a question regarding the 0.4 km radius commonly used in transit analysis. The models indicate that the 0.4 km radius is too small to capture the significant influence of the built environment on transit ridership. Document type: Article

Abstract

Transsexuality has found a place in both the Spanish collective mindset and media. To analyze the portrayal of this type of sexual diversity in the media, we evaluated its presence in cybermedia, its preeminence in journalistic texts, and the issues addressed in its media coverage. A quantitative content analysis (N = 24,363) of the journalistic texts published during the period 2000–2020 by 13 generalist Spanish cybermedia was carried out, using both rule-based classification and unsupervised topic modeling. The results highlight an increase in journalistic texts about transsexuality, in which three inflection points and four phases or distribution changes can be distinguished. The preeminence of this topic within the analyzed pieces has also increased, and the issues covered have diversified over the years. Overall, these data confirm the newsworthiness that this type of sexual diversity achieved throughout the first two decades of the twenty-first century. Media attention especially highlights the newsworthiness of aspects such as conflict, the protagonist’s notoriety, or periodicity through anniversary journalism. Likewise, the results also suggest that the media offer an increasingly complex portrayal that favors both the visibility and the understanding of the different dimensions and characteristics that intersect in these realities.
