The purpose of this paper is to explore last mile delivery (LMD) to the bottom of the pyramid in Brazilian slums, its challenges and how practitioners overcome them. Urban logistics in precarious circumstances is central to the conceptualization.

A qualitative, grounded theory methodology is developed, gathering data from companies delivering to slums in Sao Paulo and Rio de Janeiro, Brazil. Field notes, documents and interviews led to conceptual categories for LMD to slums.

The study indicates that while some standard urban logistics practices can be effective for LMD to slums, such unusual contexts often call for unusual solutions. A model is developed using grounded theory categorization, resulting in five dimensions for LMD to slums: employing locally, giving back, acknowledging criminals, vehicle and location.

The model is a qualitative proposition representing LMD to slums in two major Brazilian cities. Even though slums in different cities/countries may face similar conditions, additional studies are needed to confirm and replicate the model.

Companies that successfully engage in LMD to slums must adapt and develop idiosyncratic practices.

LMD to slums enables a larger portion of bottom of the pyramid consumers to access a wider range of products and work opportunities, contributing to their social inclusion.

The study provides an understanding of LMD in a new context. The model encourages companies to question their current practices, learning from effective LMD experiences implemented by successful practitioners.

Social factors can shape economic decisions. Corporate governance (CG) studies and guidelines usually neglect that the chief executive officer (CEO) and board members may be socially tied. This study investigates the effects of social ties between the CEO and board members on earnings management (EM).

The authors run a series of regressions using a sample of Brazilian companies listed on the Brazilian Stock Exchange [B]³ between 2011 and 2017 to assess the effect of the social ties between the CEO and board members on EM using a social ties index. The authors also employ five robustness tests to verify the consistency of results, including alternative proxies of EM and social ties and an estimation using fixed effects.

After developing and computing a social ties index between the CEOs and members of the board of directors (BD) and the fiscal council (FC), the study’s findings indicate that a significant level of social ties between the CEO and BD has a negative impact on EM. However, for FC members, the authors found non-significant results.

Unlike previous studies, the authors built a social tie index (STI) from five elements of social ties assessed in an environment with a two-tier board system. Results show that elements of social interactions and personal relationships can benefit the company, as a CEO's level of social ties with the BD reduces EM practices.

This study aims to protect Lactobacillus plantarum and Enterococcus faecium encapsulated in alginate beads during stress treatments, such as high temperatures and concentrations of sodium chloride (NaCl) and sodium nitrite (NaNO₂).

Free and encapsulated probiotics were subjected to 70 and 80°C during 5, 10, 20 and 30 min. In addition, the probiotics were subjected to concentrations of 0.5, 1.0, 2.5 and 5.0 per cent NaCl and 0.5 and 1.0per cent of NaNO₂.

Free Lactobacillus plantarum was more resistant to heat than free Enterococcus faecium. Alginate-encapsulated Lactobacillus plantarum (ALP) also was more resistant to heat treatments than alginate-encapsulated Enterococcus faecium (AEF). After 30 min at 70°C, ALP showed levels about 6.9 log CFU/g while AEF presented 4.3 log CFU/g (p = 0.005). However, at 80°C, ALP maintained levels higher than 6 log CFU/g for up to 10 min, while AEF was able to maintain those levels only for approximately 5 min (p = 0.003). Encapsulation process provided adequate protection for both probiotics against NaCl. In relation to NaNO₂ concentrations, 0.5 and 1.0 per cent reduced viability of both probiotics (p = 0.014), either as free cells or as alginate-encapsulated forms.

Alginate beads containing probiotics is an interesting alternative for application in foods such as cooked meat products.

Alginate beads elaborated with milk powder, inulin and trehalose were effective to protect probiotics in stress situations similar to those can be found in the processing of foods, such as cooked meat products.

In a dynamic, continuously evolving sports landscape, social media have become an indispensable tool for sports organizations to cultivate meaningful connections with fans. The rapid pace of technological advancements has elevated these digital platforms from a supplementary role to a pivotal position within strategic management frameworks. The existing literature explores how football clubs can utilize social media, but analyzing social media strategies within the context of football leagues is lacking. The absence of comparative studies benchmarking clubs across different geographical regions while simultaneously analyzing multiple social media platforms is especially noteworthy. In this study, a comprehensive analysis of social media engagement is undertaken within esteemed football leagues spanning Europe, South America and North America.

Drawing on relationship marketing and employing content analysis as a methodological tool, the study examined 10,772 posts from the official accounts of eight football leagues on Facebook, Twitter and Instagram.

Across the leagues, the findings reveal that content quality drives engagement more than frequency. In addition, several format combinations were identified that facilitate engagement and Instagram emerged as the top social media platform for generating fan engagement.

This is one of the first empirical studies focusing on optimizing the use of social media to amplify fan engagement across various geographies and social media accounts and formats simultaneously.
