With the worldwide growth of open telecommunication networks and in particular the Internet, the privacy and security concerns of people using these networks have increased. On the one hand, users are concerned about their privacy, and desire to anonymously access the network. On the other hand, some organizations are concerned about how this anonymous access might be abused. This paper intends to bridge these conflicting interests, and proposes a solution for revocable anonymous access to the Internet. Moreover, the paper presents some legal background and motivation for such a solution. However, the paper also indicates some difficulties and disadvantages of the proposed solution, and suggests the need for further debate on the issue of online anonymity.

The objective of this chapter is to provide an understanding of the meaning and measurements of food security.

This chapter consolidates and examines the evolution of the many definitions of food security since 1975 and describes the four dimensions of global food security. We examine the relationship between global food crisis and food security, and the significance of Brazil, Russia, India, China, and South Africa as emerging markets.

Achieving food security will be determined by the world as a group helping developing countries in creating proper infrastructures, providing better income opportunities, and reducing financial constraints.

Governments, international agencies, private firms, and the world’s population need to be involved in food security from seed to plate.

The purpose of this paper is to design and to implement an oral health educational strategy that targeted an older population residing in three social protection centers (SPC) in Villavicencio, Colombia.

The first phase consisted in determining the oral health of older citizens in the SPC. To do this, the research group gathered patients’ personal information and indices. The second phase consisted in the development of an educational strategy based on the population’s requirements. The educational strategy, focusing on oral hygiene and denture care, was implemented for the older people and their caregivers. The third and final phase consisted in the research group measuring the effect of the designed strategy by repeating oral diagnoses for the older people six months after strategy implementation.

The results of the assessment indicated that implementing a strategy to strengthen oral hygiene care was positive, given that statistically significant reductions were observed in the soft plaque index and the Gingival Index (p<0.05).

As a result of the complexity of the population, the data obtained after the strategy was implemented were significantly reduced. However, these results indicate that an educational strategy can have an effect on this type of population.

Implementing a strategy that promotes oral hygiene education and brushing skills, fosters good oral behavior and helps the older people in SPC to remember the information taught, thus contributing to their oral hygiene.

This paper aims to propose the development of formal (scientific content) and informal (content for science communication) educational activities in an inclusive and safe way, involving two essential elements, virtual reality (VR) and the digital library; as well as the implications for its enforcement such as educational strategies in the university setting and for the encouragement of scientific culture in society.

For the integration of content, a simplified conceptual model was designed first, in which universities and research centers are seen as complex systems where different subsystems, from which processes and information resources are derived, converge. To cover the model’s elements, a descriptive documentary review was developed, looking to synthesize each element’s contexts and implications.

The need to establish transdisciplinary relationships between the VR and the digital library is determined with the goal to integrate educational activities using technology, with the purpose of studying contents from the scientific point of view, as well as with the possibility of transforming them into contexts of general access for society, with the objective of social appropriation of knowledge, citizen science and social innovation. In the conclusion section, some implications in the implementation of this type of initiatives are presented.

The aspects that set this paper apart are: treating VR as emerging documents tending to measure their direct impact, not as isolated elements of a collection; identifying the digital library’s social influence actions through VR; and generating processes to encourage the creation of contents with a differentiated focus according to the population served.

Hyperglycemic diets are a critical risk factor for diabetes and other chronic diseases; therefore, food innovation is encouraged. In this sense, starchy foods with a better postprandial glycemic response (PGR) could contribute to disease prevention for consumers. This study aims to evaluate the effect of three biscuit formulations on glycemic indicators – in general, and by sex – and their acceptability.

The authors analyzed the nutritional composition of biscuits A, B and C (high, moderate and low fiber content, respectively, among other differences) and the PGR, glycemic index (GI) and glycemic load (GL) after being consumed by 15 healthy adults. A sensory evaluation was also performed (n = 54 subjects). An analysis of variance and generalized linear models were fitted to estimate the effect of formulations on glycemic indicators, including interactions by sex.

For samples A, B and C (classic biscuit) the GI was 50, 54 and 51, respectively. The formulations did not show differences in the GI or GL. Lower values of PGR were observed in women (p = 0.01) and inverse effects on glycemia in all formulations in women with respect to formulation C in men were found. Calories, fiber and monounsaturated fats showed inverse effects on the PGR, GI and GL. Sample A had the highest value of acceptability (86.1%), considering all attributes assessed.

A sex-related effect in glycemia was found, with all formulations triggered a better PGR in women. The nutritional profile of biscuits can be improved while maintaining palatability.

Most strategies for managing conflicts between social and commercial objectives of social enterprises are discussed either at the individual or at the team level of analysis. This paper aims to argue in favor of taking into account both levels of analysis at the same time. It furthermore aims to unravel how management strategies at the individual and the team level reinforce one another.

This study adopts the theoretical lenses of personal values (at the individual level of analysis) and stewardship (at the team level). The authors have conducted 23 semi-structured interviews across three Belgian social enterprises. Primary data collection was complemented with secondary data of 12 annual reports and 314 newspaper articles. The variety of cases and the richness of primary and secondary data proved useful to elaborate on the mechanisms of managing conflicting objectives.

This paper highlights four bridging mechanisms that facilitate the mitigation of conflict between social and commercial objectives, i.e. fit of values, agile structure, partnerships and communications. It also shows how these mechanisms reinforce each other at the individual and team levels of analysis and thus form an iterative process for managing the conflicting objectives of social entrepreneurs.

This paper contributes by bringing the level of analysis on managing conflicting objectives at the intersection of the individual and team performance. It argues that social entrepreneurs should target both individuals and teams at the same time, to manage effectively conflicting objectives. The four mechanisms create an alignment and reflection iterative process for managing conflicting objectives.

The main objective of this study is to understand the role that family council and protocol can have in the planning process of family companies.

To reach this general objective, the qualitative approach was used using multiple case studies: seven Portuguese family companies. Data collection techniques, interviewing, direct observation and documentary analysis were used.

Based on the empirical evidence, it is concluded that the family council and family protocol help succession planning and favour the continuity and survival of the family business. However, other working groups also support the entire planning process, such as the cousin generation meeting and the New Generation Monitoring Committee (or Mentoring Committee). The development of future personal plans for the younger generations may lie in this Committee, which assists and guides the younger family members.

This study is pioneering in Portugal because it analyses the use of new instruments that helps the succession planning process in family firm context: the family council and family protocol. These managerial mechanisms allow to achieve the success, allowing family conflicts to be minimized, the continuity of family firms and avoiding their mortality.

The study contributes to increasing knowledge about the family council, the family protocol, family firm succession and its planning. It is important and innovative by studying those topics in depth, their connection being little explored in the literature. This study can be seen as a benchmarking for governance practices in other countries.
