Abstract
Purpose
The paper aims to present a new two stage local causal learning algorithm – HEISA. In the first stage, the algorithm discoveries the subset of features that better explains a target variable. During the second stage, computes the causal effect, using partial correlation, of each feature of the selected subset. Using this new algorithm, the study aims to identify the actions that lead a student succeed or failure in a course.
Design/methodology/approach
The paper presents a brief review of main concepts used in this study: Causal Learning and Causal effects. The paper also discusses the results of applying the algorithm in education data set. Data used in this study was extracted from the log of actions of a Learning Management System, Moodle. These actions represent the behavior of 229 engineering students that take Algorithm and Data Structure course offered in a blended model.
Findings
The algorithm proposed in the paper identifies that features with weak relevance to a target may become relevant when computing the direct effect.
Research limitations/implications
The algorithm needs to be improved to automatically discard attributes that are under a specific threshold of direct effect. Researchers are also encouraged to test the proposed propositions further.
Practical implications
The algorithm presented in this paper can be used to identify the mostly relevant features given a classification task.
Originality/value
This paper computes the direct effect of a selected subset of features in a target variable to evaluate if a variable in this subset is really a cause of the target or if it is a spurious correlation.

Abstract
Economic and social inequality in Mexico presents a challenge in the transformative recovery of the country. This chapter aims to identify opportunities and multi-actor actions in the different scenarios of economic growth and sustainable development for Mexico in the coming years. We managed to propose public policy recommendations for the country by building future scenarios along with the participation of representatives from government, business, civil society and academia. A regenerative Mexico by 2030 requires policies that encourage private, domestic and foreign investment; regulatory frameworks for investment in clean technologies; implementation of tax incentives to promote a green economy and cooperative and inclusive models, such as the social and solidarity economy. Inclusive and collaborative multi-actor actions among the country's sectors become the common denominator of future scenarios for Mexico from an optimistic, resilient and hopeful perspective for its population.

Entrepreneurship and family business.
Abstract
Subject area
Entrepreneurship and family business.
Study level/applicability
The case is suitable for BA and MBA levels and for courses focusing on family businesses, entrepreneurship, or small and medium-sized enterprises.
Case overview
The Gomez family is the owner of Colchones Eldorado, a Colombian mattress company, in business for more than 50 years. Its founder and CEO Gumercindo Gomez, 75 years old, had no succession plan but he wanted to ensure the future of his business. Given the urgency of this situation and the complexity of the family structure, Martha Gomez, General Manager, hired a consultant to design the succession plan. To prepare this plan, the consultant must take into account: the preservation of stock ownership within the family, the company's sustainability under the new CEO family member, and the assurance of the family harmony.
Expected learning outcomes
These include: understanding the characteristics of a family business in the Latin American context; recognizing the stages of the family ownership; and identifying personal characteristics and roles of family members in order to design the basis of the succession plan.

Abstract
Learning outcomes
The contribution of the present case lies in the critical view that every business actor should exercise – be it general manager, middle management, supervisor or executive – when building a strong organizational culture in corrupt political environments.
Case overview/synopsis
The purpose of this case study is to explore the dilemma in which Marcelo Odebrecht, once CEO of Odebrecht, found/determined whether to continue with the business model established by the founders of Odebrecht or take a new path for the organization. After exploring the corrupt acts of Odebrecht and the scope of Operation Lava Jato, the reader can reflect on the importance of organizational culture (according to the three levels proposed by Schein) in the face of the emergence of corruption. By generating discussions about organizational culture, business ethics, political culture and corruption, the organizational culture of Odebrecht is problematized in relation to its real behavior.
Complexity academic level
Students of administration, business and international business undergraduates and graduates, as well as members of senior management in companies in the infrastructure sector. Also, given the plurality of possible readings, it is recommended that the case also be used in courses or specializations in organizational psychology, organizational sociology or organizational anthropology.
