Contact problems are among the most difficult ones in mechanics. Due to its practical importance, the problem has been receiving extensive research work over the years. The finite element method has been widely used to solve contact problems with various grades of complexity. Great progress has been made on both theoretical studies and engineering applications. This paper reviews some of the main developments in contact theories and finite element solution techniques for static contact problems. Classical and variational formulations of the problem are first given and then finite element solution techniques are reviewed. Available constraint methods, friction laws and contact searching algorithms are also briefly described. At the end of the paper, a bibliography is included, listing about seven hundred papers which are related to static contact problems and have been published in various journals and conference proceedings from 1976.

Many organizations around the world currently are facing board diversity issues and challenges. Hence, this empirical paper investigates the relationship between board diversity and firm’s financial performance. We use a sample of 35 companies from five countries in Southeast Europe (Macedonia, Croatia, Serbia, Bosnia and Herzegovina, and Greece) for the period between 2008 and 2012 to find that, on average, companies with well-educated board members are more profitable and overvalued on the market. When running the regression again to test the levels of heterogeneity, we also find that the companies with more women on board tend to be overvalued on the market, while those with more foreigners on board are subject of undervaluation. The paper mostly contributes to the literature on corporate governance and board diversity. First, we postulate the impact of each of the board diversity variables on the financial performance and then show the extent of this impact and its economic interpretation. Our findings have important practitioners’ implications for corporate regulators and policy-makers since the demonstrated positive impact of the well-educated board members on firm’s financial performance gives a new impetus in building a corporate strategy that will intend to engage more people holding PhD on board.

The purpose of this chapter is to review how well walking interventions have increased and sustained walking, and to provide suggestions for improving future walking interventions. A scoping review was conducted of walking interventions for adults that emphasised walking as a primary intervention strategy and/or included a walking outcome measure. Interventions conducted at the individual, community, and policy levels between 1990 and 2015 were included, with greater emphasis on recent interventions. Walking tends to increase early in interventions and then gradually declines. Results suggest that increased walking, and environmental-change activities to support walking are more likely to be sustained when they are immediately followed by greater economic benefits/time-savings, social approval, and/or physical/emotional well-being. Adaptive interventions that adjust intervention procedures to match dynamically changing environmental circumstances also hold promise for sustaining increased walking. Interventions that incorporate automated technology, durable built environment changes, and civic engagement, may increase cost-efficiency. Variations in outcome measures, study duration, seasons, participant characteristics, and possible measurement reactivity preclude causal inferences about the differential effectiveness of specific intervention procedures for increasing and sustaining walking. This review synthesises the effects of diverse walking interventions on increasing and sustaining walking over a 25-year period. Suggestions are provided to guide future development of more effective, sustainable walking interventions at the population level.

There are still many different theoretical approaches and practical interpretations about what an integrated report is. Starting from this premise, the overall purpose of this chapter is to critically analyze the relationship between integrated reporting (IR) and social/sustainability disclosure. Indeed, although some scholars considered IR as a tool to improve the sustainability approach of the companies allowing to disclose more relevant social information, others are more critical about the potentiality of IR to improve social disclosure. Therefore, the general research question is: Is there a natural link between IR and social disclosure (true love) or is the IR a practice to “normalize” the social disclosure and accounting (forced marriage)?

In the attempt to provide a preliminary answer to the research question, the chapter analyzes what is the approach of three categories: (1) academics; (2) soft-regulators; and (3) companies. From the methodological point of view, a mixed method of analysis has been adopted.

From the analysis of the three different points of view, IR can be considered as a “contested concept” because of the heterogeneous and sometimes conflicting interpretations and implementation that are done on this type of report. This leads to relevant theoretical and practical implications.

This paper aims to examine the measurement of intangible aspects of research and development (R&D) projects, particularly from the funding organization's point‐of‐view.

A literature review on R&D measurement is carried out in order to identify the intangible factors to be measured as well as potential indicators. The practical applicability of the measures is discussed in light of an exploratory case study.

Lists of intangible inputs and outputs of R&D projects are presented along with some potential measures. The assessment of the intangible aspects of R&D projects is considered important for the funding organization. However, the current measurement practices are inadequate.

The results provide a summary of the current status of the topic and a basis for further research.

The knowledge about the intangible aspects of R&D projects summarized in this paper has been scattered before in a wide set of previous research literature. The evaluation of the existing measures provides valuable information for understanding the development stage of this academic and managerial discipline.

The purpose of this paper is to describe the work of IDMEC, a not‐for‐profit R&D private association located in Porto and Lisbon, Portugal.

The paper focuses on IDMEC's R&D activities, focusing on aeronautics.

Together IDMEC‐Porto and INEGI provide answers to R&D challenges in the broad area of aerostructures, from fracture and fatigue problems to advanced composites for space applications.

The paper offers a concise presentation of the IDMEC's R&D activities in the field of aeronautics.
