Thinking skills are essential to achieve sustainable social development. Nonetheless, there is no specific instrument that assesses all of these skills as a whole. The present study aimed to design and validate a scale to assess complex thinking skills in adult people. A scale of 22 items assessing the following aspects: analysis and problem solving, critical analysis, metacognition, systemic analysis, and creativity, in five levels, was created. This scale was validated in 626 university students from Peru. In total, 16 experts in the field helped to determine the content validity of the scale (Aiken’s V value higher than 0.8). The confirmatory factor analysis allowed the evaluation of the structure of the five factors theoretically proposed and the goodness of fit indexes was satisfactory. An item was eliminated during the process and the scale resulted in 21 items. The composite reliability for the different factors was ranged between 0.794 and 0.867. The invariance between genders was also checked and the concurrent validity was proved. The study concludes that the content validity, construct validity, concurrent validity, and composite reliability levels of the COMPLEX-21 scale are appropriate.

Although human talent is essential to achieve social and organizational development with a sustainable focus, its definition and features remain unclear considering humanity’s current challenges and the transformation towards the knowledge society. The purpose of this conceptual analysis is to propose a new definition of talent using socioformation as its basis. The methodology used was a hermeneutical analysis due to the lack of previous published works on the subject. The main results were: 1) the proposal of a new definition of talent as a complex process which focuses on solving contextual problems with relevant results for improvement of living conditions, based on competencies, laboriousness, complex thought, opportunities for inclusion, the ethical project of life, collaboration, and continuous improvement; and 2) the new approach is characterized by emphasizing collaboration, being inclusive, and having a systematic and procedural approach. We concluded that it is necessary to approach a new perspective of talent, which contributes to the formation of citizens committed to human development with an emphasis on environmental care, against which the proposal presented in this conceptual analysis, arriving from socioformation, is only an option for discussion.

Based on the fact that malignant cancerous lesions (neoplasms) develop high metabolism and use more blood supply than normal tissue, infrared thermography (IR) has become a reliable clinical technique used to indicate noninvasively the presence of cancerous diseases, e.g., skin and breast cancer. However, to diagnose cancerous diseases by IR, the technique requires procedures that explore the relationship between the neoplasm characteristics (size, blood perfusion rate and heat generated) and the resulting temperature distribution on the skin surface. In this research work the dual reciprocity boundary element method (DRBEM) has been coupled with the simulated annealing technique (SA) in a new inverse procedure, which coupled to the IR technique, is capable of estimating simultaneously geometrical and thermophysical parameters of the neoplasm. The method is of an evolutionary type, requiring random initial values for the unknown parameters and no calculations of sensitivities or search directions. In addition, the DRBEM does not require any re-meshing at each proposed solution to solve the bioheat model. The inverse procedure has been tested considering input data for simulated neoplasms of different sizes and positions in relation to the skin surface. The successful estimation of unknown neoplasm parameters validates the idea of using the SA technique and the DRBEM in the estimation of parameters. Other estimation techniques, based on genetic algorithms or sensitivity coefficients, have not been capable of obtaining a solution because the skin surface temperature difference is very small.
