Given the importance of education‐based approaches in stimulating breastfeeding, the paper aims to investigate the feasibility and efficacy of discussing breastfeeding with school children..

Two workshops about breastfeeding and on the view of the human being as a mammal were carried out in schools in Brazil. Children were invited to express their views of breastfeeding based on what they had learned. Questionnaires were applied immediately before and 15 days after the workshops to assess the impact on children's knowledge.

There was on average a low level of knowledge about breastfeeding previous to the interventions. The interventions increased children's self‐perception as mammals, and managed to enhance their knowledge about several important issues regarding breastfeeding.

There was a fairly small number of participants and a restricted age range. More studies with other age ranges are warranted.

Educative interventions on breastfeeding targeting young school children can have very positive results, suggesting that school could successfully include breastfeeding.

This is the first study to demonstrate the impact of this innovative approach on school children's awareness on breastfeeding and it demonstrates this pedagogic approach to be effective.

This research aims to identify whether leaders' affective organizational commitment influences employees' affective commitment to both the leader and the organization. Additionally, the study explores the role of employees' emotional awareness in shaping these relationships.

Examining a sample of 154 leaders and 249 employees in multinational companies, this study adopts a multilevel approach.

The results reveal a positive influence between the two foci of commitment (leaders and organization) at both the leader and employee levels. Furthermore, it confirms that employees' emotional awareness plays a positive role in the commitment process.

This research highlights the significance of implementing internal policies and measures that consider the various foci of commitment. To foster employees' commitment, it is crucial to establish a robust alignment between human resources management and leaders.

This study delves into the exploration of two commitment foci to deepen our comprehension of the directional relationship between them in the workplace. More specifically, our research scrutinizes the impact of leaders' affective organizational commitment on employees' affective commitment to the organization, while also analyzing its reciprocal influence on employees' affective commitment toward their leaders.

The heritage and tourist attractiveness of Heritage Cities have aroused interest in establishing mechanisms to enhance their value based on the development of sustainability policies. The socioeconomic and socioenvironmental valuation of these heritage sites has become a necessary tool for decision-making.

Following the recommendations of International Council on Monuments and Sites – ICOMOS, this paper proposes a series of indicators and an exploratory model to define the factors that contribute to their valuation. Following the partial least squares structural equation modelling methodology, information was obtained from 363 intramural residents in the three Heritage Cities that currently have management plans in Spain.

The results show the importance of specifying indicators of sustainable mobility and socioeconomic and socioenvironmental sustainability for an adequate valorisation of heritage sites.

To this end, it is necessary to follow the guidelines of international bodies such as ICOMOS in relation to the management plans.

The purpose of this study is to affirm that it is possible to segment visitors of cultural heritage into homogeneous groups according to a series of characteristics to detect the variables that have statistical significance to identify visitor clusters.

Four case studies were selected, where a total of 500 questionnaires were made to visitors. The authors proceeded with cluster analysis using SPSS software to differentiate visitor segments. Four groups of visitors were first identified and which have subsequently been reduced to three, according to several factors.

The main contributions of this paper are: (1) the segment to which each one of the determinants of the cultural tourism product is dedicated; (2) the variable object of the analysis, i.e. the formation of visitor segments; and (3) the inclusion of less studied variables such as type of accommodation contracted, treatment offered in the museums or entrance price.

The analysis has been developed in different museums, with different management models, in a specific place. However, the results are generalizable to other places and to other institutions that manage cultural heritage. The implications are management strategies for a sustainable cultural development in institutions of tourism and heritage.

From a practical point of view, the results are useful for cultural managers, travel agencies, tour operators, tourism companies or political offices, among others, because they generate new ideas and strategies focused on maximizing the use of the resources of cultural institutions.

For both local and non-local agents, the knowledge of the factors that make up the groups of visitors in the heritage sites represents a strategy in aspects of marketing, promotion and distribution, thus generating capacities for the different intermediaries, and the possibility of negotiating lower prices with better benefits. It is also possible to create new products destined for other publics.

The study is original because this has not been published.

This paper aims to shed some light on the distribution of population, living in disaster risk areas in Brazil, on the intra-urban scale. The following three aspects are evaluated in this paper: the distribution of exposed population according to municipal size classification; the population density in disaster risk areas; and the municipal human development classification for the municipalities with disaster risk areas.

This research is based on an explorative approach. The main database used is a result of the association of landslide and flood risk areas to demographic census, available for 825 Brazilian municipalities. Additional databases were integrated to characterize disaster risk management and municipal human development.

The results revealed that the population exposed to disaster areas is concentrated within the capitals and small cities in the country. Moreover, disaster risk areas are densely populated even in small cities, suggesting that it is a reality faced not only by the larger cities. Finally, disaster risk areas exist even inside municipalities with a high level of human development.

These findings could contribute to the understanding of the spatialisation of disaster risk in Brazil, a primordial step for the reduction of human losses.

A novel perspective about the Brazilian population exposed to disaster risk was obtained, revealing a current issue faced by the municipalities independent of the size classification and level of human development.

The purpose of this paper is to evaluate the fatigue process through the dynamic analysis of the global structural model and local static sub-modelling in a critical detail using the hot-spot stress approach. The detail was studied in three different positions at the “Alcácer do Sal” access viaduct, and the methodologies from the IIW and Eurocode EN 1993-1-9 were compared.

In this study, the fatigue life process based on the hot-spot stress approach was evaluated using a global dynamic analysis and a local sub-modelling based on a static analysis of welded connections in the “Alcácer do Sal” railway structure, Portugal, taking into consideration the recommendations from IIW and Eurocode EN 1993-1-9. The hot-spot stresses were calculated through the static analysis of the sub-model of the welded connection for each vibration mode with the aim to obtain the temporal stresses using the modal coordinates and modal stresses of the extrapolation points. The Ansys® and Matlab® softwares were used for the numerical analysis and the hot-spot stress calculations, respectively.

The proposed methodology/approach to obtain fatigue assessment is based on the modal analysis of the global structural model and local static sub-modelling. The modal analysis was used to extract the boundary conditions to be used in the local model to determine the temporal stresses of the extrapolation points. Based on the modal superposition method, the stresses as function of time were obtained for fatigue life evaluation of a critical detail by the hot-spot stress approach. The detail was studied in three different positions.

In the present study, a global-local fatigue methodology based on dynamic analysis of the global structural model and local static sub-modelling of the critical detail using the hot-spot stress approach is proposed. Herein, the modal analysis of the global structural model supported by the modal superposition method was used to obtain the matrix of modal coordinates. The static analysis of the local sub-model for each mode from the modal analysis of global structural model was done to estimate the hot-spot stresses. The fatigue damage calculation was based on S-N curve of the critical detail and rainflow method. The IIW recommendation proved to be more conservative compared to the proposed rules in the Eurocode EN 1993-1-9. The global-local modelling based on dynamic analysis is an important and effective tool for fatigue evaluation in welded joints.

Reducing fuel consumption of unmanned aerial vehicles (UAVs) during transient operation is a cornerstone to achieve environment-friendly operations. The purpose of this paper is to develop a control scheme that improves the fuel economy of a turbojet in its full operating envelope.

A novel direct-thrust linear quadratic integral (LQI) approach, comprised by an optimal observer/controller satisfying specified performance parameters, is presented. The thrust estimator, based in a Wiener model, is validated with the experimental data of a micro-turbojet. Model uncertainty is characterized by analyzing variations between the identified model and measured data. The resulting uncertainty range is used to verify closed-loop stability with the circle criterion. The proposed controller provides stable responses with the specified performance in the whole operating range, even with after considering plant nonlinearities. Finally, the direct-thrust LQI is compared with a standard thrust controller to assess fuel economy and performance.

The direct-thrust LQI approach reduced the fuel consumption by 2.1090% in the most realistic scenario. The controllers were also evaluated using the environmental effect parameter (EEP) and transient-thrust-specific fuel consumption (T-TSFC). These novel metrics are proposed to evaluate the environmental impact during transient-thrust operations. The direct-thrust LQI approach has a more efficient fuel consumption according to these metrics. The results also show that isolating the thrust dynamics within the feedback loop has an important impact in fuel economy. Controllers were also evaluated using the EEP and T-TSFC. These novel metrics are proposed to evaluate the environmental impact during transient-thrust operations. The direct-thrust LQI approach has a more efficient fuel consumption according to these metrics. The results also show that isolating the thrust dynamics within the feedback loop has an important impact in fuel economy.

This study shows the design of an effective direct-thrust control approach that minimizes fuel consumption, ensures stable responses for the full operation range, allows isolating the thrust dynamics when designing the controller and is compatible with classical robustness and performance metrics. Finally, the study shows that a simple controller can reduce the fuel consumption of the turbojet during transient operation in scenarios that approximate realistic operating conditions.

This teaching case aims to provide in-class discussions on the commercialization and consumption of goods in spiritual markets. This teaching case is a narrative based on facts with a fictitious plot reporting the journeys of the launch, commercialization and consumption of mineral water in bottles in the shape of Father Cícero – a religious leader in Northeast Brazil – produced by Blue Spring Mineral Water in Juazeiro do Norte’s pilgrimage spiritual market.

Primary and secondary data sources were gathered. Two focus groups with pilgrims and semi-structured interviews with Blue Spring leaders and a local Church representative were conducted as primary data. As secondary data, a dossier was created holding content from newspapers and blogs online on the focal product and data from the company’s official website and social networks.

Throughout the case, the strategies and challenges of the production and commercialization of this religiously appealing product and the consumer practices adopted by different consumer profiles are unfolded.

This case intends to be a useful pedagogical tool to discuss the creation, production, commercialization and consumption of goods in spiritual markets. The case allows students to experience Blue Spring’s managers’ point of view regarding the decisions of production and commercialization of the focal product. In a broad sense, this case intends to inform future marketers of the importance of balancing commercialization in religious contexts.

The purpose of this study is to identify factors that approach and that separate the Brazilian bureaucracy from the model advocated by Max Weber. Efforts were concentrated on the discussion of aspects of historical and social foundations of society and the Brazilian state that influence its bureaucracy and in the reforms undertaken in the state apparatus. The authors selected some of its iconic moments, within the framework of patrimonialism, seeking to identify evidence of its influence in Brazilian public administration.

This study is qualitative and has interpretative background with descriptive purposes. The whole process of research was based on the literature. The interpretation of data relied on content analysis based on Bardin.

The study reveals that the prevailing bureaucratic model in Brazil, although it contains some characteristics of rational-legal model, is not yet produced the expected disenchantment, at least in public administration. In addition, it was noted that the patrimonialism bases, in which society and the Brazilian State still rely, seems to prevent the bureaucracy that was advocated by Max Weber from installing fully.

Studies dealing with bureaucracy in the context of public administration are still welcome and necessary in Brazil. This is because this country still does not admit the bureaucracy to function according to the model advocated by Max Weber.
