The rapid advancement of new technologies necessitates the adaptation of existing resources to address the evolving demands of contemporary conflicts among nations. As exemplified by the emergence of Unmanned Aerial Systems (UAS) and Unmanned Aerial Vehicles (UAVs), these technologies have become indispensable components of military drone operations. This study investigates the role of innovation models in driving Portuguese Innovation and Development, focusing specifically on military drones.

Through an examination of existing scientific and doctrinal literature, this research establishes a connection between theoretical concepts and the practical deployment of drones within the Portuguese ground forces. Employing a qualitative approach, this study follows a case study, with data collection following the principle of triangulation.

The findings of this research reveal several attributes crucial to drone utilization, such as optronic capability and drone range. These attributes are vital for ensuring high-quality, real-time imagery transmission and operational effectiveness in military activities.

This study contributes to the understanding of the implications of drone attributes for the Command, Control, Communications and Information Systems (C3IS) capabilities of the Portuguese ground forces. It highlights the importance of continued emphasis on drone development and innovation as a key priority for the Portuguese Army.

This paper aims to investigate how service providers are using their channels to support the handling of customer complaints in a technology-based business network (Tb2N) environment. It aims to discuss the implications from existing misalignments between the service delivery debilities and the complexity of the Tb2N recovery process.

This study used an exploratory case study research conducted in a Portuguese private bank. Data collection involved multiple sources for corroboration purposes, such as reports from customer complaints, semi-structured interviews, direct observation and official documents. Data were analysed to identify paths and relationships between constructs, to reduce data, to enable interpretation and to achieve valid and reliable results.

The case analysis revealed four types of Tb2N debilities: weaknesses in what concerns the channel migration to new technologies, automated physical and virtual barriers in accessing the firms’ common channel, non-automated barriers concerning the cross-training of employees and, finally, barriers concerning the service operations management.

To the best of the authors’ knowledge, this is the first attempt to characterize the service failure and recovery in a Tb2N context. Complaint management is an essential tool for managers, as failures in service delivery are inevitable and the recovery of such encounters encompasses significant challenges. For academics, this is the first effort to discuss a growing topic in the operations management literature. Further investigation is needed, and with this contribution, the authors expect to stimulate other researchers to provide their contribution.

Russia’s large-scale invasion of Ukraine has inflicted catastrophic consequences, profoundly impacting Ukrainian sustainability across the environment, society and economic dimensions.

In this study, the author has explored the key role of civil society in strengthening resilience and social justice during wartime.

This study uses a qualitative multi-method research design, combining a systematic literature review (SLR) and a single case study to understand and describe the phenomenon. The SLR provided a replicable, scientific and transparent conceptual framework, which the case study empirically validated and enriched. Additionally, the Delphi method gathered relevant insights from academic experts and Ukrainian nationals residing in the EU, enhancing this research.

This research revealed complex social dynamics and community resilience, highlighting various resilience-building efforts undertaken by voluntary organizations and emerging Ukrainian movements. The findings highlight civil society’s pivotal role in promoting resilience and addressing adversity to enhance social justice and unity in Ukraine. Specific contributions include countering disinformation, providing psychosocial support and mobilizing community efforts. Furthermore, the paper identified six key steps that epitomize societal resilience and formulated a conceptual model based on these steps.

This research offers a comprehensive and practical analysis of grassroots organizations’ efforts to sustain social resilience and unity amid war. It builds upon previous studies, extending their scope by providing empirical validation and offering new insights into civil society’s contributions to Ukraine’s defense and social cohesion. The study also explores the obstacles faced by civil society and the implications for Ukraine’s future sustainability and social cohesion.

Within this scope, we highlight the necessity of redefining auditing practices and the essential adaptation required from auditors. The primary objective is to understand comprehensively how auditor competencies can be strengthened to meet the challenges posed by innovative audit practices.

A Systematic Literature Review (SLR) was conducted to explore this theme, ensuring rigor and credibility in the outcomes. The results emphasize the importance of auditors strengthening professional competencies, embracing technological agility, and promoting ongoing professional development initiatives.

The triadic framework comprising—Auditor, Auditing Practices, and Digital Audits— forms the basis for innovative audit practices. This manuscript further discusses the transition of advanced technologies, laying the groundwork for the evolution of auditing practices. Through a systematic assessment of the literature, this study develops a framework for innovative, ethically driven, and effective auditing practices, ensuring the occupation's relevance and value. Future investigations should focus on the ethical implications of automation in auditing practices and develop innovative frameworks tailored to diverse organizational contexts.

The study addresses a contemporary issue by examining the evolving nature of auditing practices considering digital transformation. Practical implications highlight the enhancement of auditor roles in digital transformation, covering ethics, technological adaptation, and continuous development to uphold the profession's integrity. This focus acknowledges the changing dynamics of business and the growing role of technology in auditing processes.

The purpose of this study is to explore how conflicting factors create tensions that hinder the development of effective policies. It specifically focuses on the broken connections between government policies and social-economic sectors. The study intends to explain how differing and often opposing interests in creating government policy influence the learning process.

This study uses a research methodology that combines developmental work research as a framework with historical case studies for collecting data. The process starts by identifying a problem and challenges related to the Brazilian “Diesel Crisis”. Following this, an analysis of the activity system was undertaken to uncover contradictions and tensions related to policy development.

The key results of the study focus on the learning process of public policy by (1) spotting gaps between government policies and socio-economic areas, (2) finding potential sources for a learning path and shared growth, (3) identifying various conflicting interests in the development of government policy, (4) creating learning possibilities in a complex and diverse environment and (5) offering solutions for resolving conflicting relationships in government policy development.

This study highlights the importance of recognizing the complicated social setting where public policy learning takes place, emphasizing the duality of collaboration and conflicting interests among different government bodies, policymakers and community members as they use tools and rules to reach their objectives.

This study aims to determine the physicochemical and fatty acids composition of Serra da Estrela cheese (SEC), as well as health-related lipid indices, like the atherogenic and thrombogenic indices, and to evaluate the influence of producer, geographical origin and production date.

All 24 SEC produced between November 2017 and March 2018 were collected at selected certified producers and analyzed by NIR spectrophotometer and by GC. Data were statistically evaluated by chemometric tools.

In all evaluated SEC, 23 fatty acids were quantified. Cheese origin influenced nutritional and health-related lipid indices). The cheeses were characterized by a relative high abundance of saturated fatty acids (67-76%), followed by a medium content of monounsaturated fatty acids (17-25%) and by low level of polyunsaturated fatty acids (5-7%). A putative positive association between cheese consumption and healthy lipid indices could be reached.

The contents of some medium and long chain fatty acids as well as of nutritional and health indices were influenced by cheese producer, geographical origin and production date pointing out the need for standardizing production procedures.

The SEC plays a key role in the local economy, being an endogenous product with unique sensory characteristics and nutritional potential, for which the knowledge of the lipids profile and health indices is of utmost relevance.

SEC is an iconic Portuguese cheese with Protected Designation of Origin. Based on the results, like health-related lipid indices, evaluated for the first time, a positive association between cheese consumption and healthy lipid indices could be envisaged.

The prosthodontics sector is facing major challenges because of scientific and technological advances that imply a clearer definition of lines of action and decision making processes. Measuring quality of service in this sector is a complex decision problem since the perceptions of three main players need to be considered: patients, dentists and dental technicians. This study sought to develop an artificial-intelligence-based (AI-based) method for assessing service quality in the dental prosthesis sector.

Using strategic options development and analysis (SODA), which is grounded on cognitive mapping, and the measuring attractiveness by a categorical based evaluation technique (MACBETH), a constructivist decision support system was designed to facilitate the assessment of service quality in the dental prosthesis sector. The system was tested, and the results were validated both by the members of an expert panel and by the vice-president of the Portuguese association of dental prosthesis technicians.

The methodological process developed in this study is extremely versatile and its practical application facilitated the development of an empirically robust evaluation model in this study context. Specifically, the profile analyses carried out in actual clinics allowed the cases in which improvements are needed to be identified.

Although already applied in the fields of AI and decision making, no prior work reporting the use of SODA and MACBETH for assessing service quality in the prosthodontics sector has been found.

This chapter investigates the political and economic contexts of the controversy about the causes of the increase of income concentration in Brazil during the 1960s. That was the most important economic debate that took place under the military dictatorship that ran the country from 1964 to 1985. The perceived sharp increase in income inequality posed a challenge to the economic legitimation of the military regime, which had by the early 1970s achieved high rates of economic growth. This chapter discusses the apparent paradox of relatively open economic debate during a period of political repression, as well as its international dimension as reflected in the role played by institutions such as the World Bank.

Considered the largest investment for most households, buying a house requires careful and transparent analysis by all parties involved in the transaction. The aim of this paper is to propose a methodological framework allowing for the readjustment of trade-offs among risk evaluation criteria, considered of extreme importance in the lending decision process of mortgage loans.

Multiple criteria decision analysis (MCDA) has proved over the years to be effective and versatile in handling compensations among criteria. Measuring attractiveness is applied by a categorical based evaluation technique (MACBETH) to a pre-established structure of credit-scoring criteria for mortgage lending risk evaluation. This pre-established structure is currently used by one of the largest banks in Portugal.

The framework allowed the authors to provide the credit experts who participated in the study with a more informed, transparent and accurate mortgage-lending risk-evaluation system. The sensitivity and robustness analyses carried out also helped in promoting discussion and supporting the readjustments made.

The study shows the usefulness of using the MACBETH approach to assist credit analysts in making better informed decisions, and opens avenues for further research. However, due to the dependence on the participants involved, extrapolations without proper caution are discouraged.

The credit analysts who participated in this study considered the framework more discerning in terms of Basel directives.

The integration of MACBETH and credit-scoring mechanisms holds great potential for risk assessment and decision support. No prior work reporting the application of MACBETH in terms of mortgage-lending risk-evaluation is known.

This study concerns how well stock market regulators prevent trading by using trading halts when they suspect asymmetric information in the market. Security trading halts in the Portuguese stock market are analysed to measure the effectiveness of trading halts imposed by market authorities as well as their timing in interrupting and restarting trading. Stock price returns, abnormal returns and volatility are used to compare the significance of differences for pre‐and post‐halt periods. First the global sample is used to analyse abnormal returns and then it is split into good and bad news halts. A GARCH (1,1) model is also applied and found to be a more sensitive instrument on justifying trading halts. Justification for trading halts tends to rise as event window size increases, suggesting that supervisory authorities tend to spot the dominant changes better. In fact, when very short time‐sampling periods are used weaker justifications for stock halting are found. The opportunity for market authorities to interrupt trading seems to be increasing. In terms of timing they seem, on the whole, to be delayed when imposing trading halts or anticipated when authorising the restart. Nevertheless, when considering good news, although the halt tends to be late the restart seems to be on time. It is concluded that all methodologies should be jointly applied by stock watch departments of supervision authorities for detecting trading under asymmetric information, but special attention is drawn to GARCH methodologies that show superior ability for detecting changes in stock characteristics.
