Uses a rigid viscoplastic formulation to simulate hot and cold forging processes. The finite element solution uses mixed methods in which the independent variables can be velocities, pressures and deviatoric stresses. Uses interface elements both in the mechanical and the thermal analysis, to take into account the effects of contact and friction, thermal conductivity of lubricants and heat generated by friction. The code developed includes an adaptive mesh refinement, triggered by an error estimator based on energy norms evaluated from nodal stress values, recovered from a local continuous polynomial expansion, and those given by the numerical solution. Assesses the code developed, using experimental results.

An optimisation method for design of intermediate die shapes needed in some forging operations is presented. The basic problem consists of finding an optimal two‐step forging sequence by automatically designing the shape of the preforming tools. The optimisation problem is defined based on an inverse formulation. The objective function of the optimisation problem is a function describing the quality of the obtained part by measuring the die underfill. The finite element method is used to simulate the forging problem. The optimisation method is based on a modified sequential unconstrained minimisation technique and a gradient method. The sensitivity‐dependent algorithm requires computing the derivatives of the objective function with respect to the design variables defining the preform shapes. A direct differentiation method has been developed for this purpose. The optimisation scheme is demonstrated with two axisymmetric forging examples in which optimal preform dies are obtained.

Race scholars often refer to the colonization of Indigenous peoples in the Americas and the enslavement of Africans as a founding moment in the making of today's racial hierarchies. Yet their narrative of this initial moment often mischaracterizes early European states, erases Indigenous and African states, and naturalizes racial group belonging. Such practices are counterproductive to the antiracist project. Following the lead of decolonial scholarship, much recent work by historians has sought to recover and reconstruct the institutions, social structures, and agency of African and Indigenous peoples, as well as revisit assumptions about European power, institutions, and agency in their historical encounters with their continental “others.” I highlight the potential of this approach for sociologists of “race” by narrating two significant historical events in the making of the modern Atlantic world: the conquest of Tenochtitlán, the capital of the Aztec empire, and the transatlantic enslavement of subjects of the kingdoms of Kongo and Ndongo (in today's Angola) in the sixteenth and seventeenth centuries. I analyze how particular European, Indigenous, and African actors made decisions in the context of their own and others' historically situated and dynamic political and social structures. I read these historical events through the lens of decolonial scholarship, and sociological literatures on group-making, state formation, and the emergence of capitalism, to make sense of the violent social process that led to the breakup of African, Indigenous, and European political and social structures and the making of colonial and racially hierarchical social structures in the Atlantic world.

This research addresses the pressing need for comprehensive studies in the rapidly evolving field of city tourism. This study aims to understand the overall performance of the International Journal of Tourism Cities (IJTC), the structure of knowledge in city tourism research and the prevalent themes and trends arising from IJTC.

A bibliometric analysis was conducted to scrutinize the publication patterns in IJTC. This involved examining parameters such as the annual count of published articles, the keywords used in them and their respective authors.

The findings reveal that IJTC has a growing and diverse publication output, establishing itself as a reputable and influential publication within urban tourism research. The results reflect various aspects and themes in city tourism research.

The study has certain limitations. The data used for analysis was obtained exclusively from the Scopus database. The analysis was conducted using only one software package, Bibliometrix. Other software packages may offer different features for bibliometric analysis. The study relied exclusively on quantitative methods for data analysis. Qualitative methods could have provided more nuanced interpretations of the data.

Comparative analyses could be conducted between IJTC and other journals within urban tourism or related disciplines. Such research would yield valuable insights into the current state of the field and aid in identifying areas warranting further investigation.

The findings from this study can inform the decisions and actions of various stakeholders involved in urban tourism. Practitioners and policymakers can draw from this research to make informed decisions. Existing and emerging authors can identify relevant topics for their research. Readers can access pertinent information for their needs.

This study offers a unique contribution by thoroughly comprehending the performance of IJTC between 2015 and 2023. It progresses the existing body of knowledge on city tourism research by examining its current status and future trends.

The purpose of this paper is to study the portrayal of early accountants in the unfamiliar site of Portugal by examining Portuguese-language realist literature from the second half of the nineteenth century.

Two popular literary works – Uma Família Inglesa (An English Family), written by Júlio Dinis and published in 1867, and Singularidades de uma Rapariga Loura (The Idiosyncrasies of a Young Blonde Woman), written by Eça de Queirós and published in 1873 – were examined through a qualitative content analysis.

The dimensions of the accounting stereotype discerned for the two early accounting practitioners featured in these works are portrayed as: modest; on-the-job trained practitioner; uncreative, conservative and unenergetic; honest financial manager; servant of the capitalist (i.e. merchant), and warm and sentimental. The accountant stereotype depicted from 1860s to 1870s period is similar to the conventional accountant stereotype, identified as the “traditional accountant” stereotype. Variations from this stereotype, however, are identified in the local, time-specific settings of Lisbon and Oporto.

The study’s portrayal of early accounting practitioners occurs during a period of transformation marked by liberalism. It augments an understanding of the image of early accounting practitioners, reflecting their social positioning at a time of significant social, economic, political and cultural changes, thereby contributing to an appreciation of the historical legacy of the accountant stereotype in continental Europe. Importantly, a taxonomy is proposed for content analysis that can be used and developed by future researchers.

This paper aims to examine the relationships between socioeconomic development, renewable energy and the innovative process by providing: a descriptive analysis; a co-occurrence analysis of terms, thematic mapping and conceptual structure; and the typology of the textual corpus.

To analyze the relationship between “renewable energies, socioeconomic development and the innovative process,” it is necessary to build a theoretical foundation that contains the relevant scientific studies and reflects the current state of the art on the subject. For this, this study developed a systematic literature review (SLR) using the preferred reporting items for systematic reviews and meta-analyses research protocol to answer the relationship on the theme.

Research shows a global understanding of the need to invest in developing studies to reduce carbon dioxide emissions and improve economic growth. The main contributions lie in providing a typology of the state of the art, identifying the joint relationships between themes, insights into the key themes and indicating themes that must be developed. This study may also support future empirical studies as it provides a theoretical foundation for formulating hypotheses, which can be tested through qualitative and quantitative approaches.

The innovative character consists of addressing a shortage of SLRs on this theme. Thus, this paper fills this gap by providing a theoretical foundation for future scientific and academic knowledge generation. Furthermore, regarding the interdisciplinary aspects of this research as contributions, this paper presented different approaches and theoretical perspectives.
