The purpose is to analyse the nutritional adequacy and carbon footprint of intermediated meals provided to preschool children and primary-level students in a Portuguese municipality.

An observational cross-sectional study was conducted with a convenience sampling consisting of school snacks from a Portuguese municipality. The nutritional assessment used food labels and a Portuguese food composition table. The literature review for carbon footprint assessment was conducted by searching for the products under analysis or similar ones.

The results showed that 80% of snacks have a higher energy value than recommended. The majority of options are below recommendations for protein and fat and above recommendations for carbohydrates. The intermediated meals with more dairy products in composition have the highest carbon footprint. The carbon footprint included the packaging of the products, and it wasn't possible to determine the influence of non-food products.

This study has limitations in the fact that we do not know the carbon footprint of Portuguese products and we had to compare them with others, from different countries, with possibly different types of production.

Intermediate meals are inadequate, and the carbon footprint is higher when the intermediated meals include products of animal origin – the reason why the composition of intermediated meals should be redesigned considering the achievement of these targets.

The promotion of intermediated meals that promote the Mediterranean eating pattern contributes to health and well-being and is a vehicle for nutrition education and healthy food consumption in schools.

Many studies have been conducted to analyse the carbon footprint and environmental impact of school meals, but commonly lunch is the meal evaluated and the assessment of intermediated meals' impact is an open field.

This study aims to explore demographic market segments’ effect on the relationships between memorable tourism experiences (MTEs), perceived value dimensions and tourists’ behavioral intentions.

The data were collected with an online survey that gathered information on MTEs, economic value, quality value, emotional value, social value and intentions to recommend and revisit. Based on a sample of 1,003 Portuguese tourists, the research model was estimated using partial least squares path modeling.

The results reveal that MTEs have a positive impact on all four perceived value dimensions. Emotional and social value have a positive effect on recommendation intentions. Tourists from different demographic segments exhibit heterogeneous patterns regarding perceived value dimensions’ influence on these individuals’ behavioral intentions. Emotional value has the strongest impact for females, but males are influenced more by social value. Economic value significantly contributes to younger tourists’ recommendation intention, while quality value has the same effect on the 36–45 age group.

This study extended the existing knowledge by confirming heterogeneity among different tourist segments defined by age and gender regarding the relationships between MTEs, perceived value dimensions and behavioral intentions.

本研究旨在探讨人口统计细分市场对难忘旅游体验 (MTE)、感知价值维度和游客行为意愿之间关系的影响。

数据通过在线调查收集。该调查收集了有关 MTE、经济价值、质量价值、情感价值、社会价值以及推荐和重访意愿的信息。研究模型根据 1,003 名葡萄牙游客的样本使用偏最小二乘路径模型进行分析验证。

分析结果表明, MTE 对所有四个感知价值维度都有积极影响。情感价值和社会价值对推荐意愿有正向影响。在游客的感知价值维度对他们行为意愿的影响方面, 不同人口统计背景的群体表现出不同的模式。情感价值对女性的行为意愿影响最大, 而社会价值对男性行为意愿影响最大。对于年轻群体, 经济价值影响其推荐意愿, 而对于 36–45 年龄组的群体, 则是质量价值影响其推荐意愿。

本研究证明按年龄和性别定义的不同旅游群体对于 MTE、感知价值维度和行为意愿之间关系的异质性, 从而扩展了现有文献。

Este estudio buscó explorar el efecto de los segmentos demográficos en la relación entre las experiencias turísticas memorables (MTE, por sus siglas en inglés memorable tourism experiences), las dimensiones del valor percibido y las intenciones de comportamiento de los turistas.

Los datos se recogieron mediante una encuesta online que recopiló información sobre MTEs, valor económico, valor de calidad, valor emocional, valor social, intención de recomendar y de revisita. El modelo de investigación se estimó en base a una muestra de 1.003 turistas portugueses aplicando la metodología de mínimos cuadrados parciales (PLS).

Los resultados revelan que las MTE tienen un impacto positivo en las cuatro dimensiones del valor percibido. El valor emocional y social tiene un efecto positivo en las intenciones de recomendación. Los turistas de diferentes segmentos demográficos exhiben patrones heterogéneos en cuanto a la influencia de las dimensiones del valor percibido en las intenciones de comportamiento. El valor emocional tiene el impacto más fuerte para las mujeres y el valor social para los hombres. El valor económico es relevante para explicar las intenciones de recomendación para el grupo más joven y el valor de calidad para el grupo de edad de 36 a 45 años.

Este estudio amplía el conocimiento existente al confirmar la heterogeneidad entre los diferentes segmentos turísticos definidos por edad y género con respecto a las relaciones entre los MTE, las dimensiones del valor percibido y las intenciones de comportamiento.

The purpose of this paper is to provide a more comprehensive understanding of how authentic leadership (AL) can affect individual performance through creativity and organizational citizenship behavior (OCB)’s mediating roles.

The sample included 177 leader-follower dyads from 26 private and small and medium-sized organizations. Followers reported their perceptions of AL, and leaders assessed each follower’s level of creativity, individual performance and OCB.

The findings show that AL has a positive impact on OCB (i.e. altruism, sportsmanship, civic virtue, conscientiousness and courtesy), employee creativity, and individual performance. Creativity partially mediates the relationship between AL and individual performance. Some dimensions of OCB, namely, altruism, civic virtue and courtesy, also play a mediating role in this relationship.

Additional studies with larger samples are needed to determine more clearly not only AL’s influence on individual performance but also other psychosocial variables affecting that relationship.

Organizations can increase employees’ creativity, OCB and individual performance by encouraging managers to adopt more AL styles.

This study is the first to integrate AL, creativity, OCB and individual performance into a single research model, thereby extending previous research. The study also used a double-source method to collect data (i.e. leader-follower dyads) to minimize the risk of introducing common-method variance.

In the twenty-first century, the family has been turning towards a greater plurality of training paths, situations, family and parental arrangements. However, despite changes in legislation, values, representations and practices, the word family remains inexorably associated with the heterosexual bi-parental model. This paper aims to contribute to the knowledge of the family dynamics of non-heterosexual people, mainly concerning the process of transition to parenting, in relation to family changes in Portuguese society. To do so this study aims to analyze four in-depth interviews¹ with young adults, women and men who have a homoconjugality relationship and a project of parenting in mind.

Based on a qualitative methodology the study intends to discuss issues related to the challenge of heteronormativity, equality within the couple, projects and gender representations of parenthood and in particular what it means for the men and women interviewed, to be a father and to be a mother in a same sex couple and how they project themselves as fathers and mothers.

The study discusses all these issues always in relation to the biographical trajectories, the history and life as a couple and the structural and individual resources, such as school and professional qualifications. It also analyzes the main difficulties experienced in revealing their sexuality to the significant others and the difficulties / strategies they anticipate in relation to the parenting project.

The authors conclude that female interviewees show greater independence of a male figure in relation to their parental projects and anticipate less difficulty in their parental skills compared with the gay man interviewed.

To analyze the dynamics of parenting in same-sex couples, this study also points out to the need to construct a model of analysis capable of articulating structural factors, such as job insecurity and heteronormativity, biographies and individual resources and profiles of conjugal interactions.

This study aims to examine the impact of authentic leadership (AL) on employees’ organizational citizenship behaviors (OCB) by investigating the mediating effect of affective commitment (AC).

Data were collected on 194 leader-follower dyads in diverse organizations, using individual surveys. Followers reported their perceptions of AL and their AC, and leaders assessed each follower’s level of OCB.

The results support the research hypotheses proposed, confirming that employees’ perceptions of AL are positively related to both their AC and OCB. Moreover, AC completely mediates the relationship between AL and OCB, indicating that authentic leaders increase employees’ affective bonds to their organization, and therefore, strengthen workers’ tendency to engage in OCB.

Additional studies with larger samples are needed to clarify more fully not only AL’s influence on OCB but also other psychosocial variables affecting this relationship.

The findings suggest that organizations can foster employees’ AC and OCB by encouraging managers to adopt a more AL style. Authentic leaders are likely to focus on the collective as they care about their teams, the wider organization and even society’s welfare and sustainability.

Growing concerns about sustainability and business ethics and the crisis of trust in organizations can be addressed through further research on positive leadership forms such as AL. This study’s findings suggest that AL fosters employees’ affective bond to organizations and their willingness to engage in OCB, which are two indicators related to organizational sustainability.

This study integrated AL, AC and OCB into a single research model, thereby extending previous investigations. In addition, the data were collected from two sources (i.e. both leaders and followers in dyads) to minimize the risk of common-method variance.

The neighbourhoods surrounding social housing are often characterised by poverty, high rates of unemployment, community violence and other social stress factors that are often linked with adverse childhood experiences, including diverse forms of family, community and institutional violence against children. Based on the sociology of childhood, which considers children as active subjects with rights and promotes a critical understanding of their participation in matters that concern them, this chapter reviews participatory research with children, highlighting the importance of hearing their voices, to sustain their key role in building knowledge about them and the contexts in which they live. In this case, children participated in research to provide a deeper understanding of their needs in their neighbourhood, the role of their families and communities and what they needed to improve the quality of their lives.

The purpose of this paper is to collectively measure and compare the efficiency of Brazilian and American soybean transport corridors, from farmers to export ports, using the data envelopment analysis (DEA).

This paper aims to determine routes from main producing micro-regions to main export ports, specifically using slack-based measure and variables that represent the three pillars of sustainability (economic, social, and environmental). The choice of variables was guided by literature review and analyzed through the principal component analysis. After the application of the model, the quantitative tiebreaking method of the composite index is applied.

The findings are coherent with a global report that compares soybean transportation in both countries (Brazil and USA). Efficient routes and corridors tend to present short distance truck trips and long distance train or barge trips. The efficiency of the inland waterway trips depends on how many barges are used in the same expedition. Routes with more than three modes tend to be inefficient which suggest that there is a limit for multimodality.

Corridor benchmarking is a rare topic in the literature and previous works normally focus on some specific and limited corridor performance characteristics, such as cost. The main contribution of this research is that it expands the discussion regarding corridor benchmarking and it focuses on efficiency as a whole. The paper also proposes a method that can be applied in different logistics contexts, like expanding the study to different countries. More specifically, this method could be used in infrastructure investments programs.
