The Autonomous University of Sinaloa (Spanish: Universidad Autónoma de Sinaloa, UAS) is a Mexican public university based in the city of Culiacán, Sinaloa, but with several campuses across the state..
The migration of a relative to the United States transforms the experience of home for those who remain in the place of origin, yet this translocal habitability is rarely measured. Using the preliminary data cut from the pilot survey of project FZ-HAB-0026 on the Factoriza UAS platform, this study described the initial behaviour of a fifteen-item scale with three dimensions, Bond with the home at a distance, Longing for the migrant relative and Attachment to the family dwelling, among Sinaloan families with relatives in the United States. With a cross-sectional design, 12 cases out of a target of 100 were analysed while data collection remained open. Descriptive statistics, Cronbach’s alpha, McDonald’s omega total and Spearman correlations between dimensions were estimated, and an exploratory factor analysis was attempted. Internal consistency was acceptable for Attachment to the dwelling (α = .719), moderate for Longing (α = .566) and negative for Bond with the home (α = -.948); in all three dimensions, the reverse-worded item did not covary with the rest. The factor analysis was not interpretable because the sample had fewer cases than items, and no correlation between dimensions had an interval excluding zero. Missing the relative and feeling their absence on special dates received the highest ratings. The findings do not yet provide structural validity evidence and point to revisions of the instrument.
Tourism and real estate development are advancing on the coastal localities of southern Sinaloa, Mexico, yet the perceptions of their residents are rarely measured. Using the preliminary data cut from the pilot survey of project FZ-HAB-0021 on the Factoriza UAS platform, this study described the initial behaviour of a fifteen-item scale with three dimensions, Presence of tourism, Living conditions and Rootedness, in Teacapán (Escuinapa) and Chametla (El Rosario). With a cross-sectional design, 20 cases out of a target of 100 were analysed while data collection remained open. Descriptive statistics, Cronbach’s alpha, McDonald’s omega total, exploratory factor analysis and Spearman correlations between dimensions were estimated. Rootedness showed acceptable internal consistency (α = .763; ω = .786), whereas Presence of tourism (α = .355) and Living conditions (α = .277) did not behave as homogeneous scales. The factor analysis, with KMO = .325, suggested two factors: one of rootedness and a bipolar one that opposes the presence of real estate and commercial tourism to housing affordability and the sufficiency of services. Living conditions and Rootedness were positively associated (ρ = .631, 95% CI [.219, .852]). The findings do not yet provide structural validity evidence and point to revisions of the instrument.
The Mazatlán malecón is a coastal public space valued by local residents and, at the same time, a setting for experiences of insecurity. This study examined, using a preliminary data cut from the pilot survey of project FZ-HAB-0003 on the Factoriza UAS platform, the initial psychometric properties of a ten-item scale with two dimensions, Bond with the malecón and Fear on the malecón, and the association between them. With a cross-sectional design, 14 cases out of a target of 100 were analysed while data collection remained open. Descriptive statistics, Cronbach’s alpha and McDonald’s omega total, an exploratory factor analysis with minimum residual extraction, oblimin rotation and parallel analysis, and the Spearman correlation between dimensions were estimated. Internal consistency was high (α = .848 and ω = .870 for Bond; α = .812 and ω = .839 for Fear), but sampling adequacy was very low (KMO = .283). Parallel analysis suggested two factors that accounted for 66.67% of the variance and did not reproduce the intended dimensions: bond items clustered with two fear items loading in the opposite direction, while vigilance, fear of robbery and night-time insecurity defined the second factor. The correlation between dimensions was ρ = -.367, 95% CI [-.759, .222]. The findings do not yet provide sufficient structural validity evidence and point to specific revisions of the instrument before data collection is closed.
This study evaluates the structural reliability and seismic performance of reinforced concrete buildings with two different lateral load-resisting systems: (1) conventional moment-resisting frames (MRF) and (2) dual systems combining MRF with buckling-restrained braces (BRB). Both structures are assumed to be located on soft soil deposits within the lake-bed zone of Mexico City. Nonlinear dynamic analyses were performed using a suite of ground motion records representative of the local seismic hazard. The reliability assessment included the development of fragility curves and the estimation of the mean annual frequency of exceedance for key engineering demand parameters. Furthermore, the seismic performance of the building models was quantified in terms of expected economic losses using the methodology included in FEMA P-58. Results demonstrate that the incorporation of BRB significantly enhances structural reliability and reduces expected annual losses compared to the conventional MRF system. Specifically, the dual MRF–BRB building exhibited an Expected Annual Loss (EAL) of 0.43
Backyard activities (BAs) constitute a traditional rural food production strategy, although their sustainability-related outcomes remain underexplored in rural contexts. Our objective is to analyze how BAs in rural communities in the municipality of Guasave, Sinaloa, Mexico, represent a local strategy for producing healthy food through sustainable practices, focusing on the relationship between production processes and indicators associated with waste management, water use, and environmental impact. A stratified sampling approach was employed, and a structured survey was administered to 387 households practicing BAs in the region. Instrument consistency was verified using the Kuder-Richardson coefficient. Results show that BAs are relevant in the region: 89.15% of respondents have a family garden and 67.96% raise animals for domestic consumption, supporting an additional income. Chi-square tests revealed statistically significant correlations (p < 0.05) among the study variables, ranging from moderate to strong, with backyard animal husbandry practices standing out in relation to nutritional and health management in animal production, reaffirming that these are not isolated events but complementary activities. These findings indicate that BAs involve interconnected systems rather than isolated activities, reflecting an integrated household-level system with potential implications for resource management and environmental sustainability in rural contexts.
