Supply chains are among the most important, complex and risky systems in the modern world. Thus, managing risk is no longer an option, but a fundamental process in organizations. Given the lack of pathways that guide companies toward supply chain risk management (SCRM), the purpose of this study is to provide a conceptual reference, in the form of a maturity model, to support them in the evolution and improvement of this process.

The proposal covered a broad literature review, a survey and a multiple case study. The research was conducted in the aerospace industry and included companies from the supply chain of a leading aircraft manufacturer.

The model elaborated with the research results has eight attributes and four levels, addressing critical issues for SCRM to achieve its scope and purposes. The attributes include the structuring and scope of the SCRM process, the importance it receives within the organization, the resources used and the qualification of employees, the role of leadership and the inter-organizational collaboration.

Managing risk along supply chains is particularly challenging, demands resources and knowledge and requires a continuous effort. The proposed model offers a reference for improvement, helping to identify areas that need to be strengthened and practices to be implemented. Thus, it can guide the focus and efforts in a more efficient and systematic way, in addition to support evaluations and comparisons.

Although maturity models are abundant in different fields and several are available for risk management, models specifically developed for SCRM are scarce. This study broadens the understanding of SCRM with novel insights about how to improve this process in an evolutionary way. While many researchers focused their efforts on the SCRM process steps, this study identified critical issues that transcend these steps. The research was carried out in a sector with a long tradition in risk management and included companies belonging to a same supply chain, that is, using an approach still little explored in studies on SCRM or risk management maturity models.

The objective of this chapter is to describe and analyze Brazil's main steps in its long and incomplete process of organizing a professional and responsive public service. During the twentieth century, Brazil had two authoritarian regimes and organized a state-oriented process of industrialization. After 1988, democracy has changed how public administration should be constituted, imposing demands for universal recruitment and accountability. The level of professionalization of the federal public service was improved, with a higher level of education, better wages and the recruitment of public servants to management positions. The challenges ahead are improving governance and executive coordination and raising the responsiveness and quality of public management (such as human resources, planning, budgeting, procurement, information and communication technologies, and organizational modeling) in a context of political instability, slow economic recovery, and substantial public debts at the federal government.

This study analyzes the competencies toward sustainability in hotel facilities in order to identify the level of implementation of sustainability practices, as well as individual competencies for sustainability in the hospitality companies.

Interviews and a survey with hotel employees were conducted in two important touristic Brazilian cities, Florianopolis, and Rio de Janeiro, considering the TBL (triple bottom line) dimensions. The data were analyzed with content analysis and descriptive statistics and conjoint analysis.

Preventive competencies in the companies' management were identified. The research also revealed that competencies for sustainability are fairly present in the hospitality context yet, which demonstrates the urgency to discuss the theme in both academic and business practices.

The access to the hotel managers impaired the performing of a robust statistical analysis; the study provided new insights about the topics investigated and generated information for the theoretical framework about competencies for sustainability.

The research results emphasized the need for the hotel industry to invest in sustainable strategies to meet its target audience, but also to raise the level of its staff and reduce costs in the long term, offering benefits to society, the environment, and, to their businesses.

The research socially contributes through promoting discussion on sustainability, which is one of the most challenging and relevant issues for society. Besides, it can assist the diffusion of the competencies for sustainability in the hotel industry, as an attempt to decrease their negative externalities on the environment and primary audiences.

It was identified a distance between practice and the triple bottom line concept, which is linked only to environmental practices. Besides, it was found limited knowledge about the concepts of competencies in the companies.

The goal of this work is to create a computational finite element model to perform thermoelastic stress analysis (TSA) with the usage of a non-ideal load frequency, containing the effects of the material thermal properties.

Throughout this document, the methodology of the model is presented first, followed by the procedure and results. The last part is reserved to results, discussion and conclusions.

This work had the main goal to create a model to perform TSA with the usage of non-ideal loading frequencies, considering the materials’ thermal properties. Loading frequencies out of the ideal range were applied and the model showed capable of good results. The created model reproduced acceptably the TSA, with the desired conditions.

This work creates a model to perform TSA with the usage of non-ideal loading frequencies, considering the materials’ thermal properties.
