The purpose of this paper is to present an acoustics-based method for measuring turbofan nozzle exhaust thrust, while assessing the potential of scaling the methods for in-flight measurements.

Although many methods proposed for achieving in-flight thrust measurements involve complicated, sensitive and expense instruments, an acoustics-based approach is discussed that greatly simplifies the technology development pathway to in-flight applications.

Results are provided for a minimum set of sensors applied in the exhaust of a research turbofan engine at Virginia Tech, showing the difference in acoustics-measured thrust and nozzle thrust found by integrating thermocouple and Kiel probe measurements to be less than 6 per cent at the maximum fan speed examined.

Measuring accurate thrust values in flight will prove immediately valuable for installed thrust validation and engine health monitoring. Acoustics-based methodologies are attractive because of the robustness and low cost of sensors and sources. The value of in-flight thrust measurements, along with the benefits of acoustic approaches, makes the current topic of great interest for further development.

This paper presents unique applications of a time-of-flight acoustic thrust sensor, while providing an original assessment of technological challenges involved with the progression of the technique for in-flight measurements.

The study explores the connection between foresight and Artificial Intelligence (AI) methods in a community within an environment of social instability in Colombia. It aims to contribute to research on aligning these methods for future-shaping, with the goal of enhancing shared governance, peer learning and collective learning among traditional decision-makers and local communities in emerging countries. The study seeks to foster a community of social actors who are likely to engage constructively in strategic dialogues. To enhancing shared governance and learning a hybrid model is synthesized, combining foresight and computational intelligence.

The case study explores the integration of computational intelligence and foresight through Gaston Bachelard's (Bachelard, 1936) phenomenology concept of ante-perception. The mathematical representation of the cone of scenarios provides a structured way to explore multiple future pathways, allowing communities to visualize and compare different trajectories and make informed decisions amid uncertainty. The model facilitates critical reflections on present assumptions, deepening insights into future scenarios. Ante-perception challenges traditional approaches to foresight by encouraging a break from established experiences, allowing for novel insights into possible futures. When enriched by computational intelligence, this reflective process is further strengthened by quantitative approach scenario modeling.

This research develops and tests a proposal that includes the logic and methods for constructing a mathematical representation of the cone of scenarios. This process, which is interactive and deliberative, is driven by anticipation and combines qualitative and quantitative approaches within a context of high uncertainty. By combining the critical reflection facilitated by ante-perception with the predictive power of computational intelligence, the model allows communities to transcend established thought patterns and explore innovative future possibilities. This integrative approach helps them envision and work toward social self-transformation.

The article aims to identify the creation of scenarios in contexts of high uncertainty, to respond to the needs of communities in emerging countries to manage change.

This article explores a novel approach to using foresight for address collective intelligence by developing a shared future vision in high-uncertainty contexts within local communities in emerging countries. The application of the hybrid model demonstrates that foresight is a key innovative social tool for developing long-term strategic reflection and planning for territories.

In developing long-term reflective processes, explaining phenomena, mechanisms and correlations requires the use of value judgments. This set of value judgments requires a representation that facilitates their treatment, helps to account for their behavior during the inference process to form a shared future vision. Consequently, ensuring the recognition of the opinions of local communities through participatory discussion spaces and their subsequent refinement, from a technical perspective, aims to illustrate the development of this social construction process. While similarities exist, differences add value through a transfer process, often subconscious. This process stimulates collective learning and builds capacities as knowledge is developed through inquiry, evaluation, interpretation and generalization.

This research provides a unique hybrid model that fosters collective learning and engagement by integrating local community perspectives with advanced computational intelligence methods. By facilitating both reflective and quantitative approach future-shaping, it offers a practical framework for addressing uncertainty while empowering communities to shape their own futures. It underscores the importance of recognizing local community views through bottom-up participatory discussions, thereby widening the stakeholder community to active engagement in addressing broader societal issues. The case study focuses on community collaboration in Puerto Gaitán, a Colombian municipality.

The purpose of this paper is to examine the role played by the visual arts in expressing and shaping the nation brand. In doing so, it establishes the centrality of visual discourse in nation branding; illustrating that discursive strategies can directly alter the nation brand’s perception.

This single case study drawing on in-depth interviews, field observation and secondary/historical material, applies mediated discourse analysis and critical discourse analysis to capture a transitional period in the cultural policies and nation branding rhetoric across a time frame of 60 years.

This study establishes the visual arts as a significant carrier of meaning, thus reflecting changes in the national discourse. This analysis illustrates that publicly supported visual arts can articulate policy aspirations and provide insight into the power of competing national discourse which co-exists, thereby shaping the internal and external nation brand.

The study focuses on the visual arts and the context of Venezuela. Future research could expand this to look at the visual arts in other national or regional contexts.

The paper establishes visual art as central to expressing national identity and policy, and a tool for examination of national identity and policy. More broadly, the paper establishes public support for the (visual) arts as central to nation-branding projects providing insight for those engaged in such campaigns to prioritize arts funding.

The authors’ study indicates the marketing relevance of visualization of the nation through the arts and establishes the visual arts as a central tenant of the nation brand.

For five surprising years, from 1968 to 1973, Peru achieved the near miracle of social reform combined with good economic growth. As if in revenge, the classic catastrophes that have plagued so many Latin American countries when they have tried to move in new directions then surged up to stop the process: a foreign exchange crisis, accelerating inflation, paralysed growth, rising unemployment, and intensified social conflict. Was all this necessary? What might have been done better? And what might be done now to resume growth without further taking apart the reforms?

The purpose of this paper is to analyze the relationship between financial and operational performance and the application of two different talent management (TM) models: internal talent development model and external talent capture model. Comparative case studies of the Football Club Barcelona and the Real Madrid Football Club allow drawing a definitive conclusion for TM in companies related to the competitive strategy.

The two TM models are examined via a longitudinal comparative case study analysis: FC Barcelona and Real Madrid CF. Present paper builds on secondary sources: first, the TM properties of the clubs were extracted from academic sources and newspapers; second, data used to analyze the financial performance were derived from SABI database and operational performance was measured as the effectiveness in winning trophies in football championships (data gathered from Union of European Football Associations and International Federation of Football Associations databases).

The case analysis reveals that the two TM models offer equally effective financial and operational performance outcomes. The internal talent development model would be more useful for companies whose competitive advantage is achieved through differentiation through teamwork. However, companies that do not achieve a clear differentiation through teamwork should opt for the external talent capture model.

Talent is one of a company’s most important intangible assets. Although there exists a growing interest among companies as to the best way to TM, practical models on how to manage talent are virtually nonexistent. Comparative case studies from the sports arena allow for the extraction of lessons for companies related to TM and competitive strategy.
