Archaic period hunter-gatherers of the Lower Pecos Canyonlands of southwest Texas and Coahuila, Mexico, created complex rock art murals containing elaborately painted anthropomorphic and zoomorphic figures. These figures are frequently portrayed with dots or lines emanating out of or into their open mouths. In this article, we discuss patterns in shape, color, and arrangement of this pictographic element and propose that artists used this graphic device to denote speech, breath, and the soul. They communicated meaning through the image-making process, alternating brushstroke direction to indicate inhalation versus exhalation or using different paint application techniques to reflect measured versus forceful speech. The choices made by artists in the production of the imagery reflect their cosmology and the framework of ideas and beliefs through which they interpreted and interacted with the world. Bridging the iconographic data with ethnohistoric and ethnographic texts from Mesoamerica, we suggest that speech and breath expressed in the rock art of the Lower Pecos was tied to concepts of the soul, creation, and human origins.

Background: Successful evaluation capacity development (ECD) at regional, national and institutional levels has been built on a sound understanding of the opportunities and constraints in establishing and sustaining a monitoring and evaluation system. Diagnostics are one of the tools that ECD agents can use to better understand the nature of the ECD environment. Conventional diagnostics have typically focused on issues related to technical capacity and the ‘bridging of the gap’ between evaluation supply and demand. In so doing, they risk overlooking the more subtle organisational and environmental factors that lie outside the conventional diagnostic lens.Method: As a result of programming and dialogue carried out by the Centre for Learning on Evaluation and Results Anglophone Africa engaging with government planners, evaluators, civil society groups and voluntary organisations, the author has developed a modified diagnostic tool that extends the scope of conventional analysis.Results: This article outlines the six-sphere framework that can be used to extend the scope of such diagnostics to include considerations of the political environment, trust and collaboration between key stakeholders and the principles and values that underpin the whole system. The framework employs a graphic device that allows the capture and organisation of structural knowledge relating to the ECD environment.Conclusion: The article describes the framework in relation to other organisational development tools and gives some examples of how it can be used to make sense of the ECD environment. It highlights the potential of the framework to contribute to a more nuanced understanding of the ECD environment using a structured diagnostic approach and to move beyond conventional supply and demand models.

In the modern market economy conditions, financial information is very significant when evaluating the results of enterprises’ financial status and activity results. General economic, mathematical, heuristic methods are used for this type of analysis. The article analyses application opportunities for one of the mathematical research methods–time series–as well as its research instruments, discusses the place and role of interpolation methods in a financial analysis. The article reveals that interpolation methods which may be used to determined former values of an enterprise’s financial indicators or identify reasons which determined the enterprise’s financial status and activity results are the following: 1) graphic and arithmetic interpolation in a linear equation; 2) geometric interpolation based on the compound percentage formula and 3) interpolation by averaging.
