Tensile Strength: A Pedologist's Perspective on Variability in Cohesive and Non‐Cohesive Horizons From Brazil's Coastal Tablelands

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Previous research has underscored the importance of evaluating soil consistency for accurate determination of cohesive character and mechanical properties. Although qualitative assessments by pedologists are pertinent, they exhibit inherent subjectivity that may compromise accuracy.

Measuring Organizational Resilience in a Resource‐Constrained Environment: An Empirical Study of Micro‐and‐Small‐Service‐Enterprises (MSSEs) in Nigeria

Strategic Change, EarlyView.
ABSTRACT There is growing evidence that a preponderance of resilience indicators discussed in management scholarship is often developed with limited consideration of the context in which micro‐and‐small‐service enterprises (MSSEs) operate. Given their strategic relevance to developing economies, it thus becomes necessary to understand the meaning of ...
