This study aims to analyze the phenomenon of entrepreneurial spawning in the new context of software startups, revisiting theory and identifying patterns within the emergence of startups/spin-offs in Brazil.

A study of two cases of startups recognized for generating several spin-offs founded by former employees. The authors based the data collection on the following triangulation: 11 in-depth interviews, systematic analysis of 33 resumes from entrepreneurs in spawned firms and document analysis.

Six skills developed in startups were identified: (1) structuring a company, (2) people management, (3) strategic/operational planning, (4) commercial/sales, (5) product development, and (6) behavioral traits. In addition, points of contradiction concerning the literature were found, such as the absence of the location effect, different professional experiences and new local agents to support startups.

The present study covers only two cases in the context of software startups, which requires caution and discretion in extrapolating to other contexts.

The understanding of the phenomenon may reflect in: university programs focused on internships in startups, corporate training programs for entrepreneurs and the design of public policies based on entrepreneurial spawning.

The present study stands out for its access to data from high-impact startups in Brazil, in addition to revisiting the literature bringing a new perspective to the specificities of high-growth software companies.

In this article, the author discusses the influence of technological development on the survival of European parties since the Second World War.

The database comprises more than 200 parties and the political forces observed in 20 countries.

The author find that Internet users as a proportion of the population and a higher value of secure servers in an economy tend to strengthen the duration of parties since their first electoral participation.

This is the first paper discussing parties' survival in democratic regimens as depending on the technological development.

Recently, a new class of fatigue crack growth models based on elastoplastic stress‐strain histories at the crack tip region and strain‐life fatigue damage models have been proposed. The fatigue crack propagation is understood as a process of continuous crack initializations, over elementary material blocks, which may be governed by strain‐life data of the plain material. The residual stresses developed at the crack tip play a central role in these models, since they are used to assess the actual crack driving force, taking into account mean stresses and loading sequential effects. The UniGrow model fits this particular class of fatigue crack propagation models. The purpose of this paper is to propose an extension of the UniGrow model to derive probabilistic fatigue crack propagation data, in particular the derivation of the P–da/dN–ΔK–R fields.

An existing deterministic fatigue crack propagation model, based on local strain‐life data is first assessed. In particular, an alternative methodology for residual stress computation is proposed, based on elastoplastic finite element analysis, in order to overcome inconsistencies found in the analytical approximate approaches often used in literature. Then, using probabilistic strain‐life fields, a probabilistic output for the fatigue crack propagation growth rates is generated. A new probabilistic fatigue field is also proposed to take mean stress effects into account, using the Smith‐Watson‐Topper (SWT) damage parameter. The proposed models are assessed using experimental data available for two materials representative from old Portuguese bridges.

A new method to generate probabilistic fatigue crack propagation rates (P–da/dN–ΔK–R fields) is proposed and verified using puddle iron from old Portuguese bridges, usually characterized by significant scatter in fatigue properties. Also, a new probabilistic fatigue field for plain material is proposed to deal with mean stress effects.

A relation between the P–ε–N and the P–da/dN–ΔK–R fields is firstly proposed in this research. Furthermore, a new P–SWT–N field is proposed to deal with mean stress effects.

This chapter discusses how young Black people produce social agency through the sphere of culture, based on hip-hop. Divided into two parts, it surveys theses and dissertations produced in Brazilian universities on the subject in the last ten years. In a second moment, it proposes a research methodology that takes young people as narrators of their social experiences, emphasizing how they think about the school space. The work is an exploratory study and seeks the interposition between formal schooling and the cultural practices of hip-hoppers. It intends to affirm hip-hop as a power, an affirmative form of an ethic of life, a way of life, and a way of escaping the established places for poor, Black young people from the suburbs. It is also intended to show how hip-hop, a marginal culture, has triggered a game of cultural positions within the school and displaced provisions of power.

This article presents the current situation of Ouro Preto, the first Brazilian city to be inscribed on the World Heritage List of UNESCO (United Nations Educational, Scientific and Cultural Organization) in 1980. It explores the evolution of the urban form, especially concerning public policies and development strategies as the motors to prompt the city's expansion.

Landscape architecture concepts were employed to understand impacts caused by the settlement within its urban landscape. In addition, urban morphology methods were used to research the urban form considered as a product of public policies, shaped by political, social and economic forces. In this manner, building typologies and new urban forms occupying the surrounding hills of the historical city's core were viewed as urban morphology issues, whereas the impact of the new housing scheme on the land and on the city skyline was a subject related to landscape architecture.

In general, it was observed that the public policies that have been implemented mainly control individual buildings, rather than whole homogeneous areas. Consequently, this has been contributing to environmental damage and the loss of the city's character.

The added value of the article is its contribution to studies focusing on uncontrolled expansions, as well as the occupation of the city's surrounding hills, as it explores the evolution of the city by considering it a product of society's actions that materialise through public policies.

The city of São Paulo, as one of the World’s mega‐cities, has considerably increased the quantity of commercial floor space recently, with around 160,000m² added in this sector in 1998 and another 400,000m² planned for 1999. For this post‐occupancy evaluation (POE), the building chosen was a recently designed office building, considered to be high‐tech which has a total of 34 floors including six underground levels, 1,033m² of useful area per floor and circulation of more than 3,000 people per day. The unique situation of the different users, with their particular layouts, is an area that has still not been analyzed in POEs in Brazil. This paper will present the results of a pilot POE applied to four floors occupied by the headquarters of a manufacturer of domestic appliances, focusing on the methodological approach.

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.

The purpose of this study is to present a general review that provides an overview of the concept of sustainability and the effectiveness of mathematics curricula in courses where deeper work on economic and environmental sustainability has become central.

A qualitative methodology consisting of a review based on a pre-defined systematic method was used to exhaustively search and identify the most relevant answers to the research question: What is the role of mathematics to sustainability? To facilitate answering such a broad question, several concrete questions were formulated. Answers from published and unpublished documents were analysed. The quality of the extracted data was assessed, and the results were synthesized.

It was concluded that, on the one hand, the discipline of mathematics has much to contribute to solving the problems of sustainability; on the other hand, new mathematics is appearing stimulated by new challenges.

This work presents social implications in an innovative way. It allows for an increase in educational sustainability by bringing the academic community closer to the business world and the challenges of society and, furthermore, by having a major impact on the motivation of teachers and students to develop cooperative work within university institutions.

The originality is based on an a priori analysis for the construction and implementation of didactic tools for university teacher training in the area of mathematics within the framework of sustainable development, both economically and environmentally.

This chapter analyzes the role of new local planning frameworks in the development of urban megaprojects (UMPs). It argues that the way projects are integrated with existing planning controls and statutory procedures influences how its costs and benefits are distributed. Drawing on the case studies of the Special Hudson Yards District in New York City, the “Zone d’Amenagement Concerte Clichy-Batignolles” in Paris and the Operacao Urbana Agua Branca in Sao Paulo, it compares how the legislative reforms and strategic plans enacted in each city impacted development programs, implementation process, and public benefits delivered by each project. This is a comparative case study analysis using quantitative and qualitative data collected through planning documents, press articles, interviews, and field research on the planning process of the three case studies, their administrative and institutional frameworks focused combined with quantitative analysis of the development proposals and outcomes of each project. The research shows how the articulation between the new plans and the underlying zoning districts as well as willingness by the city to commit public funds to finance the required upfront investments influence the ability of cities to extract public benefits from urban megaprojects and improve integration with surrounding neighborhoods, transport infrastructure, and regional policy. Based on a succinct review of the related literature the chapter illustrates the evolving role of public agencies and land-use regulation in the development of UMPs, illustrates the material expression of strategic planning on legislative reform and policy statements, provides a comparative analysis of contrasting legal systems, and suggests policy formulations that can improve the “public return” generated by UMPs.

This article aims at the understanding of specific spaces where entrepreneurship education (EE) happens – inside and outside the classroom.

Building on frameworks such as formal versus non-formal entrepreneurial education and institutional versus non-institutional actors, this research applies structural equation modeling (SEM) to explore which spaces entrepreneurs attended as undergraduate students. Going beyond intentionality, the authors collected data from 175 respondents in Brazil, all of the respondents are entrepreneurs whose companies are at least one year old.

Results demonstrate that student-led activities are as important as institutional ones when training future entrepreneurs, while specific in-classroom activities feature the lowest impact among the institutional ones.

Sample size and characteristics could impact the generalization power, but, since the results fit within research criteria, researchers can benefit by reflecting over new research horizons, going beyond classroom studies and understanding the university as an ecosystem of learning interventions.

Results can be useful to university managers when designing institutional policies, fostering a diverse set of undergraduate experiences towards entrepreneurship training.

Although current literature has focused on classroom education, researchers have been pointing out the need of stepping out of the classroom, analyzing other spaces such as student-led movements, co-curricular programs and more.
