Thisstudy aims to evaluate the ecological, social, economic, institutional, and infrastructural sustainability of the Maros–Watampone road corridor that crosses TN Babul. Using a qualitative descriptive design, the research employed theMultidimensional Scaling (MDS) method supported by leverage and Monte Carlo analysis. Data were gathered fromkey stakeholders through purposive sampling and analyzed based on sustainability attributes across five dimensions.The findings reveal that environmental, institutional, and infrastructure dimensions scored in the "less sustainable"category, indicating high ecological risk and governance gaps. In contrast, economic and social dimensions weremoderately sustainable, reflecting emerging opportunities for inclusive growth. Sensitive attributes influencingsustainability include habitat fragmentation, road design, governance coordination, and community participation. Thestudy concludes that balancing development with conservation requires integrated, multi-stakeholder strategies andtargeted interventions that address the most vulnerable sustainability dimensions.展开更多

The results indicate that poverty in its multi-dimensions is an epidemic problem in rural Iran. The results also exhibit that there are 11 patterns of poverty in the rural areas including four main patterns with 99.62% coverage and seven sub-patterns with nearly 0.38% coverage. In these patterns, housing and household education are the most important dimensions of poverty and income poverty is the least important dimension. Government income support policy to households, in enforcement the law of targeting subsidies, cannot be regarded as pro poor policy but it follows other political aspects.展开更多

Jenner’s and Wang Yitong’s translations of Luoyang Jialan Ji (547 AD) from a multidimensional perspective. Statistics show that both the two translations belong to the General Narrative Exposition Register. However, there are significant discrepancies between the two versions in Dimension 1 “Involved versus Informational Production”, Dimension 4 “Overt Expression of Persuasion” and Dimension 5 “Abstract versus Non-Abstract Information”. The differences in Dimension 2 “Narrative versus Non-Narrative Concerns” and Dimension 3 “Explicit versus Situation-Dependent Reference” are not that significant. It is found that in Dimension 1, the information density of Wang’s version is much higher than that of Jenner’s. In Dimension 4, Wang’s version contains more overt persuasive effort than Jenner’s. In Dimension 5, the positive and negative contrast between the two versions indicates that Wang’s version provides information in a more abstract way, whereas Jenner’s in a relatively non-abstract way. Combined with typical examples in the two translation versions, this study is hoped to help better understand the translations of Luoyang Jialan Ji and conduct future studies on the translation styles of the two translators.展开更多
