This study consists of 284 interviews of people dedicated to labor activities in different public zones in the city of Bogotá, Colombia. The results indicate that informal workers include individuals of different ages, with the majority being adults; and there is an increasing trend in participation from individuals with high levels of education, showing that low educational levels are not sufficient to explain informal street work, especially in situations of displacement such as that caused by violence in Colombia in recent years. Instead, the main reasons for engagement in informal work are limited opportunities and low wages in the formal labor market, as well as the desire for work autonomy. While informal workers recognize the arduosity of informal street labor, they maintain positive concepts of themselves and their work, as these activities allow them to support their family while serving others in their communities. This article provides reflection on the conditions of informal street workers and provides understanding of the problem in order to better design strategies to overcome discrimination and exclusion.}, publisher = {Mediterranean Journal of Social Sciences}, title = {Informal Workers in the Streets: An Integral View}, doi = {10.2478/mjss-2018-0156}, author = {Bernal Torres, César Augusto and Peralta Gómez, María Claudia and Zwerg Villegas, Anne Marie and Cabrejos Burga, Raúl}, }@misc{10818/32748, year = {2016}, month = {7}, url = {http://hdl.handle.net/10818/36962}, abstract = {The purpose of this paper is to explore the relationship between civil conflict and educational achievement in Colombia through the use of pseudo-panel analysis.

As such, devising efficient methods for freight transportation planning is of paramount importance. One of the most crucial aspects affecting the efficiency of freight transport is the variability in travel speeds, impacted by factors such as traffic congestion. While traditional approaches often rely on GPS technologies and associated routing services-which can be expensive-for planning, these methods also necessitate frequent re-optimization due to ever-changing traffic conditions. To address these challenges, we introduce a novel solution that integrates real-time traffic data into daily vehicle route planning. Specifically, our method incorporates Google Maps API for traffic congestion estimation and utilizes a Mixed Integer Linear Programming (MILP) model to determine optimal routes for an entire day. We tested our methodology in a major U.S. city and found that it outperforms conventional approaches by up to 18% in terms of routing time, underscoring its practical relevance and efficiency. © 2024 The Authors.

Through an ethnographic exploration of sensory expertise, this article brings detail to the question of what makes up flavor expertise and how it is valued, juxtaposing the work of the high-end chef with that of the flavorist—a producer of flavorings for mass-produced foods and beverages. These two worlds of flavor are generally differently valued (i.e., chefs are seen as creative geniuses, while flavorists are considered fraudulent tricksters). However, as the article will contend, these worlds are actually closer than is recognized and share common ground in the development of sensory acuity. As an analytic framework, the concept of acuity understood as keenness of understanding and feeling is used and how acuity-in-action operates in both fields is illustrated. Overall, the article makes a case for studying expertise ethnographically, by suggesting that the traditional approach to sensible skills, with its subjectivist bias and emphasis on physiological traits, is insufficient insofar as it neglects the communal space where flavor becomes an object of concern and appropriation.

In spite of its relevance, literature on VRPLCs is still limited. The majority of the solution approaches have concentrated on heuristic solution methods, and few have presented mathematical optimization models to help characterize the problem. Furthermore, few studies have considered several practical loading and routing constraints that could be used to approximate the problem toward more realistic situations. To help fill this gap in the literature, this article extends an existing VRPLC optimization model to a nonlinear optimization model that considers weight-bearing strength of three-dimensional items, vehicle weight capacity, weight distribution inside vehicles, delivery time windows, and a balanced fleet of vehicles. The model is solved by applying a simple procedure that isolates the nonlinearity of the model. Computational experiments show that the new proposed model gives a more streamlined formulation than the model it extended on, and that the addition of practical loading constraints can improve the solutions of the original model by reducing the measure of tardiness due to late deliveries and by producing cargo patterns with better weight distribution. © 2018 The Authors.

The research explores how various competing retail formats influence market choice and demand. We used data from a survey conducted in Sabana Centro, Colombia, in this study. Originality: We believe this is the first study examining the nanostores’ resilience in serving emerging markets under this novel hybrid technique. Research method: We propose a multi-agent-based model mimicking nanostore survival and resilience in a competitive market. Household agents use a discrete choice model to select their preferred retail format for household purchases based on location, price, and service levels. Considering supply breakdowns, we tested the outcoming model under different disruption scenarios. Main findings: Results indicated nanostores’ great resiliency in competitive markets, specifically in peripheral areas, which are usually neglected by other retail formats. This suggests that this retail format can strategically complement household supply in underserved areas, displaying the importance of supporting these channels and generating tools that improve their performance in the market. Implications for theory and practice: Theoretically, we aim to improve the understanding of households’ decision-making process when buying food.

Therefore, it is necessary to develop tourism management based on sustainable tourism, mainly in the transport process. Tourist itinerary planning is a complex process that plays a crucial role in tourist management. This type of problem, called the tourist trip design problem, aims to build personalised itineraries. However, planning tends to be biased towards group travel with heterogeneous preferences. Additionally, much of the information needed for planning is vague and imprecise. In this paper, a new model for tourist route planning is developed to minimise CO2 emissions from transportation and generate an equitable profit for tourists. In addition, the model also plans group routes with heterogeneous preferences, selects transport modes, and addresses uncertainty from fuzzy optimisation. A set of numerical tests was carried out with theoretical and real-world instances. The experimentation develops different scenarios to compare the results obtained by the model and analyse the relationship between the objectives. The results demonstrate the influence of the objectives on the solutions, the direct and inverse relationships between objectives, and the fuzzy nature of the problem. © 2021 by the authors.

Additionally, this research seeks to underscore the transformative role of women entrepreneurs-for-peace (WE4P) in a post-peace agreement society. Design/methodology/approach: This study seeks to contribute to theory building on sustainable business models (SBMs) at the base of the pyramid (BoP) theory from a single case study of the Colombian microfranchise TechOil. The theoretical sampling process guided the selection of data sources, which include semi-structured interviews, company and microfranchise donors’ reports, websites and external expert interviews to support the findings. The research adopts a framework of intro-entrepreneurship characteristics, ambiance, organization and sustainability. Findings: TechOil offers a valuable case study for understanding how the phenomenon of microfranchise as an SBM spills over the BoP and promotes gender equality. The authors also developed a new SBM typology by extending the theory inductively. Practical implications: The paper highlights WE4P and introduces microfranchises as a new SBM typology, offering insights into policy, practice and societal transformation in post-peace agreement zones. Originality/value: The issue of WVC entrepreneurs in post-peace agreement settings remains under-reviewed and under-theorized. This study’s originality lies in introducing microfranchises as a new SBM typology, emphasizing the importance of gender equality and women’s roles in sustainable development and addressing the overlooked link between entrepreneurship and peace, contributing to global applicability. © 2023, Emerald Publishing Limited.}, publisher = {Management Research}, title = {Sustainability and women entrepreneurship through new business models: the case of microfranchises in post-peace agreement Colombia}, doi = {10.1108/MRJIAM-04-2023-1407}, author = {Pérez-Morón J and Thoene U and García Alonso R.}, }@misc{10818/32748, year = {5}, url = {http://hdl.handle.net/10818/52240}, abstract = {We estimate the effects of peer benchmarking by institutional investors on asset prices.

Design/methodology/approach Interview data collected from Wayuu entrepreneurs in La Guajira region of Colombia and from Māori entrepreneurs in the Rotorua region of New Zealand were analyzed qualitatively. The analysis primarily focused on Wayuu entrepreneurs, with the results for Māori entrepreneurs used for comparison, to help to interpret the Wayuu data. Findings For Wayuu entrepreneurs, family members play a range of crucial roles in enterprise operations, with the family and the kin-centered local Indigenous community emerging as an informal organization surrounding the enterprise. Family is the source of Indigenous culture, while the mainstream culture is centered on global Western business culture, rather than the culture of the country. The Indigenous entrepreneurs integrate the values of the two cultures in managing their enterprises, thus acting as n-Cultural. Māori entrepreneurs who managed enterprises with a strong Indigenous character were similar in this respect to Wayuu entrepreneurs.

Excluding serial defaulters like Argentina, our focus lies on countries still susceptible to the Twin Ds phenomenon amidst high debt levels. We find that global economic spillovers significantly influence the Twin Ds in these markets; with fluctuations in the US term spread serving as an indicator of broader shifts in global economic conditions. Our analysis reveals asymmetric spillover effects, particularly during periods of positive and increasing spreads such as the Global Financial Crisis, where changes in the term spread disproportionately impact the depreciation tail in currency markets and the high-risk tail in sovereign CDS markets. Notably, such effects are absent in stock markets, which accentuate the particular dynamics of currency and sovereign debt markets. The asymmetry of spillover effects although still present during the most recent Covid-19 crisis, was less pronounced, which may be linked to the accumulation of international FX reserves in the region during the last decades.

Methodology: This research uses legal technique and case-law analysis as research methodologies, offering a detailed panorama of the normative development of the PA and its relationship with the constitutional requirements regulating the international relations of Colombia. Conclusion: Despite being at an initial stage in relation to its normative and institutional structure, the PA has emerged as a second generation regional trade agreement (RTA), which complements its commercial trajectory with political, social and productive integration agendas, promoting the diversification of international economic relations of its members without altering or modifying their sovereign powers. The above allows to show its compatibility with the constitutional mandate pro integratione, particularly in regard to the ideal of promoting the internationalization of Colombian economic relations with countries of Latin America and other world regions. Originality: The proposed approach has theoretical and methodological originality inasmuch as there are no previous studies analyzing the legal and normative nexus between the interests of Colombia’s foreign policy and the PA.

This surge calls for novel strategies to optimize vehicle utilization while maintaining timely delivery. In response, many online retailers are incentivizing customers to embrace delayed home deliveries by offering economic incentives. Nonetheless, current transportation systems fall short in accommodating orders with extended delivery windows, primarily adhering to the First-In-First-Out rule and distance minimization via the Vehicle Routing Problem (VRP). In this paper, we introduce a new consolidation-based delivery methodology that addresses these challenges. Our approach accounts for orders with daily-based time windows and also anticipates future demand realizations (i.e., expected incoming orders). We characterize this consolidation problem using a Mixed Integer Linear Programming model and propose a custom metaheuristic approach that can tackle the problem on a large-scale setting, introducing a significant novelty approach in last-mile delivery research. We applied our methodology to one of Mexico's largest retailers and compared its performance against the company's existing transportation systems. O approach substantially improves vehicle utilization and yields considerable reductions in distance traveled, time, and overall transportation costs, achieving cost savings of up to 52%. These savings represent tangible benefits, enabling potential revenue enhancements for businesses and cost-effective, timely deliveries for consumers. Additionally, the increased vehicle utilization implies fewer vehicles are needed for the same volume of deliveries, thereby enhancing operational efficiency. This innovative approach, therefore, presents a practical and highly effective solution for managing large-scale last-mile delivery scenarios. © 2023 The Author}, publisher = {Expert Systems with Applications}, title = {A large-scale last-mile consolidation model for e-commerce home delivery}, doi = {10.1016/j.eswa.2023.121200}, author = {Muñoz Villamizar, Andrés Felipe and Velazquez Martínez J.C. and Caballero Caballero S.}, }@misc{10818/32748, year = {2021}, url = {http://hdl.handle.net/10818/52156}, abstract = {Nowadays, Supply Chain Networks (SCNs) must respond to economic, environmental, social, and uncertain considerations.

The unique set of arc costs in the CVRP is replaced by a set of discrete scenarios. A scenario is for instance the travel time observed on each arc at a given traffic hour. The goal is to build a set of routes using the lexicographic min–max criterion: the worst cost over all scenarios is minimized but ties are broken using the other scenarios, from the worst to the best. This version of robust CVRP has never been studied before. A Mixed Integer Linear Program (MILP), two greedy heuristics, a local search and four metaheuristics are proposed: a Greedy Randomized Adaptive Search Procedure, an Iterated Local Search (ILS), a Multi-Start ILS (MS-ILS), and an MS-ILS based on Giant Tours (MS-ILS-GT) converted into feasible routes via a lexicographic splitting procedure. The greedy heuristics provide the other algorithms with good initial solutions. Tests on small instances (10–20 customers, 2–3 vehicles, 10–30 scenarios) show that the four metaheuristics retrieve all optima found by the MILP. On larger cases with 50–100 customers, 5–20 vehicles and 10–20 scenarios, MS-ILS-GT dominates the other approaches.

This juxtaposition of traditional machismo attitudes towards women along with progress in women’s leadership participation make this setting ideal for examining a topic of continued worldwide debate: women’s career advancement. This study examines attitudes towards the career advancement of women—a historically marginalized group in Latin America. Building on the extant literature, we test the negative association between traditional gender role orientations and attitudes towards women’s career advancement, both directly and via a mediated relationship through acceptance of women in the workplace. We then theoretically and empirically extend this literature by examining an important context-related moderator—a company’s international proactiveness—which we contend serves as a mechanism for keeping traditional machismo attitudes from manifesting. We examine these relationships within a sample of 973 respondents within the Latin American countries of Argentina, Bolivia, Brazil, Chile, Colombia, Dominican Republic, Ecuador, Mexico, Panama, Peru, and Venezuela.

To achieve the above, organizational resilience would also seem to be critical, as it is a capacity which enables the organization to build a risk-aware culture that helps it better position itself to deal with the demands of high-impact events as well as to be able to find opportunities through uncertainty. Yet, both corporate sustainability and organizational resilience are organizational capabilities that can nourish (and/or be nurtured by) a corporate purpose that leads organizations to have a clear and inspiring sense of direction, fostering the development of strong responsible and adaptive behaviors. Nevertheless, the academic traditions that relate and explain “how” these concepts are related are non-existent.

In most industrial practice, the implementation of picking and slotting optimization techniques uses information based on historical data that, in most cases, would fail to work because of many factors affecting daily operations in the warehouse. Simulation models have been employed to build virtual scenarios in order to predict the outcomes of a specific operational decision. Simulation models also fail because collected data is not fully reliable. In order to overcome those problems, this paper proposes the use of a hybrid simulation and optimization approach in which real-time data is incorporated thanks to radio-frequency identification (RFID) technology. Operational decisions are hence made in real-time.

Military rations must provide military personnel with suitable nutrition, as high-quality nutrition is crucial for promoting health. Aim: This systematic review provides information regarding the nutritional design of military rations according to energy and protein intake and supplements. Methods: A systematic search was conducted for articles published to date regarding the nutritional needs involved in a military diet for an active population of either gender, ranging from 18 to 60 years old, without excluding material by year, type of document, location, or author. The pertinent articles found were published from 1994 to 2017. Results: Physical activity and environmental factors directly affect calculating energy needs and carbohydrate intake when designing military rations. However, the results showed no influence on protein, fat and/or sodium intake. Furthermore, the search revealed that military populations have a high intake of dietary supplements; it is thus worth considering their incorporation into campaign rations. Conclusion: Military personnel macro- and micro-nutrient needs depend on physical activity and nutrient intake measurement methodologies. The data regarding military personnel dietary supplement consumption indicated that this is a niche worth considering when designing military rations. Research on nutritional needs for military rations could concentrate on optimizing the amount of macro- and micro-nutrients and their biological value, according to physical activity, as well as maintaining their sensory quality, safety and shelf life using different processing technologies.}, publisher = {Nutrition and Health}, title = {A systematic review of the nutritional implications of military rations}, doi = {10.1177/0260106018820980}, author = {Sotelo Díaz, Indira and Blanco Lizarazo, Carla María}, }@misc{10818/32748, year = {2021}, url = {http://hdl.handle.net/10818/52154}, abstract = {Sustaining continuous improvement activities is one of the biggest challenges that companies face.

Among the most challenging operations in disaster relief is food aid supply, particularly in long-lasting humanitarian assistance. Food aid supply requires the design of inventory optimization methods adapted to disaster relief contexts to tackle over-stock, significant wastage levels, shortage, and protocols to distribute non-perishable items, such as canned tuna and rice, among others. This is due to the uncertain and changing conditions of disaster relief operations. In addition, most humanitarian food supply chains are unable to handle perishable products because of the lack of resources needed to perform the required logistic operations, respecting product shelf-life constraints. This study evaluated the capability of different humanitarian food supply chain configurations to distribute perishable products, such as vegetables and fresh meat, which can be obtained in agronomic-based economies, and can aid in providing the means for food distribution as well as the likelihood of fulfilling social and cultural aid based on the characteristics of the population. Consequently, a dynamic system model was proposed for comparing centralized and decentralized supply chain configurations. Further, the experimental results, considering a natural disaster in Colombia, facilitated the evaluation of the sensitivity of the system’s key performance indicators in humanitarian logistics in terms of agility, recovery time, and efficiency in specific echelons.

Colors are important in an economic analysis. This study aims to analyze the paintings executed by Jean-Michel Basquiat (the famous street artist from the 1980s' New York City) and sold at auction to study the potential effect of color intensity, luminosity and color contrast on the prices of his paintings. The authors also study the case of the op art master, Carlos Cruz-Diez, as a robustness analysis to the main results. The analysis that the authors present may be of interest to academicians and to participants in the art market. Design/methodology/approach: The authors run a hedonic regression model considering 306 paintings (executed by Basquiat alone), and 41 works painted collaboratively between Basquiat and Warhol and sold at auction (2003–2017). The data and the images corresponding to each painting were hand-collected from the websites of several auction houses and complemented with information obtained from the Artprice and Blouin websites. Findings: Increases in color intensity, luminosity and color contrast have a positive effect on art prices. The authors also find that color intensity is even more recognized (as reflected by higher prices) for paintings belonging to Basquiat's most appreciated (understood as most expensive) artistic period (1980–1983) and during the second part of the sample period (2011–2017). The authors find similar results for Cruz-Diez. The authors also estimate that Basquiat's artworks made collaboratively with Andy Warhol are worth 55% less than those made only by Basquiat. An investment in Basquiat's paintings generated an average annual compounded return of 16.81% (2003–2017), clearly overperforming the S&P 500. Research limitations/implications: The main limitation of the hedonic regression method lies in the need to have a significant and varied sample to identify the true effect of each variable on the price of the good. Another limitation is that we are only able to use art prices from auctions, as this is the only comprehensive source of data that is publicly available. These two limitations are common to all studies that use the hedonic pricing model. This paper has implications not only for the art pricing (and more generally, asset pricing) literature, but also for the fields of psychology and marketing. Originality/value: This is the first paper that highlights the importance of analyzing the price impact of color intensity throughout the artistic periods of a painter, finding that color intensity is even more appreciated (as reflected by higher prices) for paintings belonging to an artist's most recognized period.

Other forms of expression (e.g. sculptures and installations) are generally ignored, in part because they are three-dimensional and, hence, more difficult to measure. We analyze the price determinants as well as the return and risk of three artistic expressions (paintings, drawings and sculptures) executed by Fernando Botero, the most expensive living Latin American artist, to analyze the degree to which their risk and return attributes differ throughout a 20-year period. Design/methodology/approach: We analyzed all paintings, drawings and sculptures executed by Botero and sold at Sotheby’s and Christie’s between 2000 and 2020 (a total of 707 artworks). The data and the images of each artwork were obtained from the web pages of these two auction houses. A hedonic regression was run to explain the price of each artwork and use explanatory variables that are standard in the literature. Art price indices for paintings, drawings and sculptures were constructed using the year-dummy variables estimated in the regressions. We performed a similar analysis for another artist, Carlos Cruz-Diez, as a robustness to our results. Findings: The performance of Botero’s sculptures through time differs markedly from that of his paintings and drawings. Our results suggest that it is possible that returns estimated in the literature could suffer from a bias, as they have usually ignored the performance of sculptures and other artistic expressions. Botero’s paintings provided a return that was comparable to those of his sculptures (3.36% and 3.20%, respectively), they were two times as high as those of his drawings (1.68%). On the other hand, whereas paintings and drawings had similar annual standard deviations (26% and 25.22%, respectively), sculptures had a much smaller standard deviation (16.96%). Research limitations/implications: A limitation of the hedonic regression method lies in the need to have a significant and diverse sample to identify the true effect of each variable on the price of a good. Another limitation is that we were only able to use art prices from auctions, as this is the only comprehensive source of art price data that is publicly available. These two limitations are shared by all the studies that use the hedonic pricing model. Practical implications: Our results have practical applications for art collectors and investors, as well as for artists, galleries and, in general, for the whole art market ecosystem. The risk and return attributes of the various artistic expressions of an artist can be different, and thus it makes sense to analyze each one of them individually, as well as their correlations with the other artistic expressions and with traditional and other alternative investments. Social implications: The art market is part of what is known as the “orange economy” (also known as the Creative Economy). According to the World Bank, the economic value of the creative sector is not well known or appreciated, even though cultural, creative and artistic activities are vital for our sense of well-being. Originality/value: To the best of our knowledge, this is the first paper that compares the financial performance of paintings, drawings and sculptures for the case of a specific artist. We chose Botero for three reasons. First, he is a Latin American living artist who has achieved the highest levels of international sales. Second, Botero has worked extensively on various artistic expressions (oil paintings, drawings on different materials and sculptures) throughout his life, a characteristic that is essential to be able to carry out our study. Third, there is a long record of auction sales for each of Botero’s artistic expressions. © 2024, Emerald Publishing Limited.}, publisher = {Academia Revista Latinoamericana de Administración}, title = {Do the different expressions of an artist offer the same financial performance over time?

The participants were able to search for packaging flavor labels more rapidly when the color of the packaging was congruent with the flavor label (e.g., red/tomato) than when it was incongruent (e.g., yellow/tomato). In addition, when the packaging color was incongruent, those flavor labels that were more strongly associated with a specific color yielded slower reaction times and more errors (Stroop interference) than those that were less strongly tied to a specific color. Importantly, search efficiency was affected both by color/flavor congruence and association strength.

The linear economy model, based on “take, make, use and waste” of products and resources, has discarded potentially valuable resources and caused serious contamination problems. In contrast, the circular economy (CE) model is a strategic paradigm whose purpose is to regenerate and conserve resources through closed material loops and the sustainable use of energy in its processes. Therefore, a growing number of companies are applying different tools and techniques to implement the CE principles to innovate their products, services, and processes, achieving promising results. Thus, the main objective of this study is to suggest an implementation model named “Circular clock” based on a set of tools and techniques which firms may use for implementing CE. Design/methodology/approach: The paper presents an empirical analysis based on the triangulation method that includes three different data sources: semi-structured interviews in Spain, academic literature and books, and non-academic publications from institutions and consultancy firms. Findings: The most relevant result of this study is the proposal of a Circular Clock model for circular economy implementation is based on six fields of action define in the academic literature: take, make, distribute, use, recover, and industrial symbiosis. Moreover, this study may serve as guidance in facilitating the strategic adoption of eco-innovation practices in firms' transition to a CE. Research limitations/implications: The sample of companies that participated in the triangulation is exploratory; however, this limitation is overcome by reviewing academic literature and institutional reports. On the other hand, academics could expand the selection of tools with subsequent studies. Practical implications: The current study is based on the triangulation method, which was vital to balance the theory and practice provided by academic sources, reports, and books. In addition, this study has improved our understanding of the goals or intentions that may motivate firms to implement the CE and align them with the suggested set of tools. Consequently, this study is relevant to support practitioners in selecting a tool based on the goal they want to achieve towards circular economy implementation. Social implications: This research suggests several tools; however, each organization could adapt some that it already knows. Therefore, firms and implementation leaders should customize the circle with short lines in each case. Moreover, the clock bells represent the deadline considering that every CE implementation process requires a deadline to ensure its success in micro-level or firms. Originality/value: The “circular clock” provides a didactic way for sustainability leaders, consultants, or companies to facilitate the implementation of the circular economy by choosing the field of action on which they want to focus and the most appropriate tool according to their strategy, objective, and budget. Therefore, this model is based on the balance between theory and practice. © 2023, OmniaScience.

As an example, the palm oil supply chain is considered. This study is carried out under the focus of the “closed-loop supply chain (CLSC) framework” in which forward and backward product flows are considered simultaneously.

BRT systems are highly efficient and relatively low cost when compared to rail-based systems. In Colombia, BRT systems are the main public transportation solution in many cities such as Bogotá, Cali, Barranquilla or Pereira. One of the major challenges in BRT systems is the formation of bus queues at busy stations, which reduces the performance of the entire system. The modelling of these queues is challenging as they arise from the complex interaction between the station’s geometry, the service frequencies and the passenger demand. In this paper, we present a complete microsimulation framework for the Megabus BRT system in Pereira based on cellular automata. The simulation introduces two kinds of agents: buses and passengers, interacting to reproduce realistic behaviour. Our results show that the simulation can reproduce queues formation and delays arising from the interaction between buses and with the traffic lights. Our framework allows the evaluation of different service frequency schemes from the operator’s and the passenger’s point of view, making it a suitable tool to solve the frequency optimization problem successfully accounting for bus delays. ©ECMS Daniel Grzonka, Natalia Rylko, Grazyna Suchacka, Vladimir Mityushev (Editors) 2024.}, publisher = {Proceedings - European Council for Modelling and Simulation, ECMS}, title = {Simulation of the complete operation of a bus rapid transit system using cellular automata}, author = {Camargo O.J. and Uribe-Laverde M.A.}, }@misc{10818/32748, year = {2023}, url = {http://hdl.handle.net/10818/62328}, abstract = {Innovation plays a key role in business success, and technology policy is essential to explain why some companies achieve better innovation results than others.

Design/methodology/approach: This exploratory descriptive study used a survey of 919 executives and non-executives of 59 enterprises from different economic sectors in Bogotá. Information was gathered via a questionnaire elaborated by the researchers consisting of 11 closed multiple-choice questions. Findings: Results indicate that in the participant enterprises knowledge management activities do not have any emphasis either on the use of technologies or on activities relating to individuals’ behaviour as sources of competitive advantage, as occurs in North American enterprises (emphasising the intensive and effective use of technologies in their different activities), and in Japanese enterprises (emphasising the development of individuals’ potential as their competitive advantage). Research limitations/implications: It is an exploratory and descriptive study from which it is not pertinent to make generalisations of the previously described results about the whole group of enterprises in Bogotá motivating the development of new studies that allow the in-depth identification of the true role of knowledge management activities in enterprise performance. Practical implications: Contributes to the empirical knowledge of business reality and to the need for designing strategies allowing a better use of knowledge management to improve the competitive capacities of enterprises. Social implications: Contributes to the reflection on the importance of the essential differences providing sustainable competitive advantages to nations, organisations, and individuals over prolonged periods of time understanding knowledge as the strategic resource of contemporary society.

For example, management style can be held to be a variable with a major impact on the organization because it affects the definition of organizational objectives while coordinating and controlling resources. Therefore, this study presents a proposal for the characterization of management models and presents in the form of a causal chart what could be considered a matrix framework for an organizational management model.

Design/methodology: This scoping literature review rigorously identifies the most relevant research and variables pertaining to financial inclusion and social innovation. Findings: Based on a scoping literature review, a comprehensive framework of key concepts of financial inclusion, scholarly contributions, countries and variables is presented. Research limitations/implications: Owing to the methodological approach of this paper and its rather theoretical nature, this research seeks to enrich scientific debates pertaining to the empirical data displayed, especially on the case of Colombia.

A framework that explains how these three concepts are related and effectively merged for long-term corporate survival are proposed. Design/methodology/approach: A systematic review is carried out. It is explained, first, initial search strategies to identify those documents that define each concept and to identify concepts with which each concept is associated. Subsequently, it is designed a search strategy combining all three concepts and their associated concepts to gather and analyze all the possible studies that have tried to connect these concepts. Finally, it is identified some gaps in the understanding of how these three concepts are related. Findings: Results indicate that corporate sustainability, organizational resilience and corporate purpose merge to achieve long-term corporate survival. There exists a two-way relationship between these three variables. Findings also present gaps and future directions that should be addressed to foster an increase in knowledge about the relationships between corporate sustainability, organizational resilience and corporate purpose. Originality/value: Nowadays, some authors endeavor to explain how aspects such as corporate sustainability, organizational resilience and corporate purpose are crucial in the dynamic environment facing corporations every day. Nevertheless, there needs to be more understanding of how these three concepts are related and effectively merged for long-term corporate survival.

This study sought to modulate the flavor development of chocolates by establishing controlled processing conditions during the transformation from seed to bean in a laboratory setting, to produce superior quality chocolates. Our experimental setup comprised two varying temperature levels (30 °C and 45 °C) and three organic acids (OAs: acetic, lactic, and citric acids) at concentrations of 1–30 g/L to adjust the pH of the transformation system. Our study focused on how these conditions affect the development of distinct flavor profiles in chocolate bars, emphasizing the enhancement of fine-flavor notes. Flavor development was monitored through the untargeted metabolomics of cocoa beans and analyzing the volatile compounds and sensory profiles of the resultant chocolates. This study revealed that OA concentration markedly influenced metabolite formation, particularly affecting peptides, volatile organic compounds, and flavor notes. Chocolates derived from seeds processed with 30 g/L acid solutions demonstrated enhanced fruitiness and acidity, whereas those processed with 1 g/L acid solutions exhibited pronounced nuttiness and cocoa taste attributes but lower acidity. These findings underscore the significance of meticulously managing flavor development processes to produce fine-flavored chocolates with unique aromatic profiles. Crucially, variables in the controlling process, such as temperature and pH, are essential for fine-tuning flavor attributes, enabling the correlation and identification of key quality biomarkers to elucidate flavor development pathways. © 2024 The Authors}, publisher = {Food Research International}, title = {Modulating fine flavor cocoa attributes: Impact of seed-to-bean transformation under controlled conditions on metabolite, volatile and sensory profiles}, doi = {10.1016/j.foodres.2024.115109}, author = {Dahiana Becerra L. and Yolanda Ruiz-Pardo R. and Vaillant F. and Viviana Zuluaga M. and Boulanger R. and Santander M. and Escobar S.}, }@misc{10818/32748, year = {2014}, month = {7}, url = {http://hdl.handle.net/10818/35844}, abstract = {The protection of minorities in Central Europe became a deeply controversial issue in the aftermath of World War One.

Even though the availability of technology has increased and it is easier than ever to obtain all kinds of data, there is a lack of agreement on how to correctly measure environmental performance, and companies could suffer from an overload of environmental information. The biggest challenge, therefore, lies in how to measure and obtain the appropriate environmental data and how to interpret and relate these data to the company’s productivity.

Findings: The paper maintains that the historical social and cultural forces that were configured in the New World shaped the institutional features of the Anglo-Saxon corporate states with liberal capitalism and the Hispanic patrimonial states with hierarchical capitalism, and that these features are related to the predominant organizational corporate governance forms in North American and Latin American firms, respectively. Originality/value: This paper provides insights into the social, cultural and institutional factors that gave rise to corporate and patrimonial states and their relationships with the different types of organizational corporate governance. It introduces a categorization into the literature with three types of organizational corporate governance (e.g. corporatist, patrimonial and hybrid). This allows progress in linking corporate governance theories with a managerial focus and governance perspectives oriented to economic and social development. © 2024, Emerald Publishing Limited.}, publisher = {Journal of Management History}, title = {Social, cultural and institutional forces in corporate and patrimonial states and their relations with corporate governance: a North–South contrast}, doi = {10.1108/JMH-02-2024-0017}, author = {Martínez Avella, Mario Ernesto and Jiménez-Aguilar C.}, }@misc{10818/32748, year = {2009}, month = {4}, url = {http://hdl.handle.net/10818/48615}, abstract = {Nowadays, implementing collaboration strategies between the members of the supply chain has been an important research topic to obtain a more reactive and flexible supply chain in the highly competitive markets.

This article is devoted to the study of information sharing between the members of a supply chain in a dynamic context.

Mathematical models are providing for each case. A solver allows us to find the optimal solution in small problem instances, while a Simulated Annealing algorithm is proposed to deal with large problem instances. In the latter, the initial solution is obtained using the well-known Nawaz-Enscore-Ham algorithm, and two local search operators are evaluated.

Nonetheless, little is known about EU Ecolabel evolution; it is not clear what the drivers that encourage its implementation are. Thus, this study aims to assess the growing acceptance of the EU Ecolabel in the European Union, and Spain more specifically, by examining product and service categories and geographical regions. Methods The methodological approach taken in this study is a mixed methodology based on the triangulation method by consulting the EU Ecolabel scheme database, EU Ecolabel delegates from some autonomous regions, and the academic literature. Also, a geographic analysis was run in the ArcGIS Software with data about the accumulation of licenses assigned in 2016. Results and discussion The analysis shows that most products in Spain that have been awarded the EU Ecolabel belong to the following categories: Do-It-Yourself Products (paint and varnish), Paper Products, Cleaning Up Products, and Electronic Equipment. At the same time, the study showed that this ecolabel faces significant obstacles in its diffusion, such as the competition with environmental labels launched previously in Europe and other regional labels. Conclusions The results of this study indicate the existence of five drivers that may encourage the implementation of EU Flower in a region: (1) public management, (2) communication strategy, (3) sustainable public procurement criteria, (4) local income per capita, and (5) international trade incentives. Finally, this study provides essential recommendations for policymakers to trigger ecolabeling practices such as the need to improve the understanding of the EU ecolabel impact in different levels of activity, which means countries, regions, industrial clusters, firms, and consumers. Also, this investigation identifies areas for further research, and it expresses the need to develop business case studies about ecolabeling with the objective to visualize this phenomenon as an eco-innovation process.}, abstract = {Objetivo La Etiqueta Ecológica Europea (Flor de la UE) tiene la misión de fomentar la producción más limpia e influir en los consumidores para promover la transición de Europa hacia una economía circular. No obstante, se sabe poco sobre la evolución de la etiqueta ecológica de la UE; no está claro cuáles son los impulsores que alientan su implementación. Por lo tanto, este estudio tiene como objetivo evaluar la creciente aceptación de la etiqueta ecológica de la UE en la Unión Europea, y España más específicamente, mediante el examen de categorías de productos y servicios y regiones geográficas. Métodos El enfoque metodológico adoptado en este estudio es una metodología mixta basada en el método de triangulación consultando la base de datos del esquema de etiqueta ecológica de la UE, los delegados de etiqueta ecológica de la UE de algunas regiones autónomas y la literatura académica. Asimismo, se ejecutó un análisis geográfico en el Software ArcGIS con datos sobre la acumulación de licencias asignadas en 2016. Resultados y discusión El análisis muestra que la mayoría de los productos en España que han obtenido la etiqueta ecológica de la UE pertenecen a las siguientes categorías: Productos de bricolaje (pintura y barniz), Productos de papel, Productos de limpieza y Equipos electrónicos. Al mismo tiempo, el estudio mostró que esta ecoetiqueta enfrenta importantes obstáculos en su difusión, como la competencia con las etiquetas ambientales lanzadas anteriormente en Europa y otras etiquetas regionales. Conclusiones Los resultados de este estudio indican la existencia de cinco impulsores que pueden fomentar la implementación de EU Flower en una región: (1) gestión pública, (2) estrategia de comunicación, (3) criterios de contratación pública sostenible, (4) renta local per cápita y (5) incentivos al comercio internacional.}, publisher = {The International Journal of Life Cycle Assessment}, keywords = {Circular economy tool}, keywords = {Eco-innovation}, keywords = {Ecolabeling}, keywords = {Environmental certificates}, keywords = {EU Flower}, keywords = {Spain}, title = {Challenges for ecolabeling growth: lessons from the EU Ecolabel in Spain}, title = {Retos para el crecimiento del ecoetiquetado: lecciones de la etiqueta ecológica de la UE en España}, doi = {10.1007/s11367-019-01611-z}, author = {PrietoSandoval, Vanessa and Mejía Villa, Andrés and Ormazabal, Marta and Jaca, Carmen}, }@misc{10818/32748, year = {2018}, month = {8}, url = {http://hdl.handle.net/10818/47785}, abstract = {Changes in social organization and food systems in a community could be understood through the modifications that occurred to cookware in a specific period of time as these artifacts are not only thought for a final purpose but also represent the values, beliefs, and meanings of the culture that has created them.

This analysis was carried out by reviewing documents that describe the cookware used by indigenous peoples before the Spanish settlement, the social shifts that occurred through the alterations of those utensils, and the views that Spaniards had of the “new” lands and its peoples.

Design/methodology/approach – Based on a sample with 117 papers, this paper presents a systematic review on the integration of lean and green in the agri-food sector. Findings – Key findings indicate that research on lean and green topics has increased in recent years, an important gap in the integration of lean and green in the agri-food sector has been identified. Two paths that remain open for further research are detected: the lack of theoretical, prescriptive and quantitative research and the possibility of integrating the two most used tools of lean (i.e. value stream mapping) and green (i.e. life-cycle assessment). Practical implications – This study does not only advance the theoretical knowledge of the lean and green field, but it is also beneficial for agri-food companies who aim to effectively deploy lean and green in their processes in order to improve both operational and environmental performances. Social implications – No other industry matches in such a complete way the agri-food industry’s challenge of sustainability that is due to the amount of resources it consumes and its interrelatedness with the well-being of humanity. Originality/value – There are separate streams of established research on lean and green management in the agri-food sector, yet very few authors have addressed the intersection of these strategic initiatives.

This chapter presents a novel procedure based on Bacterial Phototaxis, called Global Bacteria Optimization (GBO) algorithm, to solve combinatorial optimization problems. The algorithm emulates the movement of an organism in response to stimulus from light. The effectiveness of the proposed meta-heuristic algorithm is first compared with the well-known meta-heuristic MOEA (Multi-Objective Evolutionary Algorithm) using mathematical functions. The performance of GBO is also analyzed by solving some single- and multi-objective classical jobshop scheduling problems against state-of-the-art algorithms.

This surge calls for novel strategies to optimize vehicle utilization while maintaining timely delivery. In response, many online retailers are incentivizing customers to embrace delayed home deliveries by offering economic incentives. Nonetheless, current transportation systems fall short in accommodating orders with extended delivery windows, primarily adhering to the First-In-First-Out rule and distance minimization via the Vehicle Routing Problem (VRP). In this paper, we introduce a new consolidation-based delivery methodology that addresses these challenges. Our approach accounts for orders with daily-based time windows and also anticipates future demand realizations (i.e., expected incoming orders). We characterize this consolidation problem using a Mixed Integer Linear Programming model and propose a custom metaheuristic approach that can tackle the problem on a large-scale setting, introducing a significant novelty approach in last-mile delivery research. We applied our methodology to one of Mexico's largest retailers and compared its performance against the company's existing transportation systems. O approach substantially improves vehicle utilization and yields considerable reductions in distance traveled, time, and overall transportation costs, achieving cost savings of up to 52%. These savings represent tangible benefits, enabling potential revenue enhancements for businesses and cost-effective, timely deliveries for consumers. Additionally, the increased vehicle utilization implies fewer vehicles are needed for the same volume of deliveries, thereby enhancing operational efficiency. This innovative approach, therefore, presents a practical and highly effective solution for managing large-scale last-mile delivery scenarios. © 2023 The Author}, publisher = {Expert Systems with Applications}, title = {A large-scale last-mile consolidation model for e-commerce home delivery}, doi = {10.1016/j.eswa.2023.121200}, author = {Muñoz-Villamizar A. and Velazquez-Martínez J.C. and Caballero-Caballero S.}, }@misc{10818/32748, year = {2019}, month = {4}, url = {http://hdl.handle.net/10818/48526}, abstract = {This paper studies the dynamics of horizontal and vertical coordination arising from a set of sectoral and intersectoral projects in the border areas of Colombia–Venezuela and Brazil–Argentina.

Findings Results indicate that 1) of the set of factors that contribute to the achievement of franchise objectives, personnel motivation and continuous environmental scanning are the most important; 2) the primary sources of knowledge for construction of competitive advantage are clients and providers; and 3) the most significant impact of knowledge occurs in human resource and organizational development and in increased earnings. Practical implications The study provides evidence of the role and the impact of knowledge in the performance of franchised restaurants and thereby contributes to academic analysis and managerial decision-making. Originality This study provides aggregated and disaggregated analysis of empirical data on the role of knowledge in franchised restaurants, a sector with limited extant research in the context of emerging markets.}, abstract = {Objetivo El objetivo de este estudio es analizar la importancia del conocimiento en el logro de los objetivos organizacionales (metas organizacionales a largo plazo) y en la construcción de una ventaja competitiva (valor agregado) e identificar el impacto de este conocimiento en el desempeño organizacional de los restaurantes franquiciados en un mercado emergente. .

Corn flour was mixed with 15, 30, and 50% of cowpea flour and extruded for this proposal. After extrusion, mixtures were ground to produce a powder. Techno-functional properties of powders as water content, hygroscopicity, water absorption, fat absorption, water solubility index, swelling index, bulk density, Hausner ratio, Carr index, and porosity were evaluated in the mixtures, extrudates, and obtained powders to assess the effect of the addition of cowpea on these properties. Results showed that processing powder obtained by extrusion and drying could be used as a powder to regenerate with water as a source of protein. Moreover, storing processing samples in sections (pellet format) is convenient to avoid wetting since this format is less hygroscopic and the same mass occupies less storage volume than powders.}, publisher = {Foods}, title = {Techno-functional properties of corn flour with cowpea (vigna unguilata) powders obtained by extrusion}, doi = {10.3390/foods12020298}, author = {Sotelo Díaz, Luz Indira and Igual, Marta and Martínez Monzó, Javier and García Segovia, Purificación}, }@misc{10818/32748, year = {2022}, url = {http://hdl.handle.net/10818/55726}, abstract = {The socio-emotional condition during the COVID-19 pandemic subsidises the (re)modulation of interactive neural circuits underlying risk assessment behaviour at the physical, emotional, and social levels.

The threats of social disconnection are processed by some of the same neural structures that process basic threats to survival. The lack of social connection can be “painful” due to an overlap in the neural circuitry responsible for both physical and emotional pain related to feelings of social rejection. Indeed, many of us go to great lengths to avoid situations that may engender these experiences. Accordingly, this work focuses on pandemic times; the somatisation mentioned above seeks the interconnection and/or interdependence between neural systems related to emotional and cognitive processes such that a person involved in an aversive social environment becomes aware of himself, others, and the threatening situation experienced and takes steps to avoid daily psychological and neuropsychiatric effects.

This method empowers us to discern the repercussions of distinct uncertainty sources on the worldwide economy by introducing inherent contemporaneous constraints into the data generation process—an approach not feasible when confined to a single-country perspective. Our analysis unveils that financial uncertainty triggers an immediate, adverse influence on most of the Real Estate Investment Trust (REIT) markets across the globe, with this negative effect persisting for a span ranging from one to three quarters. In contrast, the impact of macroeconomic uncertainty exhibits a spectrum of responses. Numerous nations do not undergo a detrimental effect on their respective REIT markets. In certain instances, there is even a favorable reaction observed approximately 1 year later. This positive response suggests that housing markets beyond US borders may derive advantages from heightened US uncertainty, potentially attributed to the diverse investment opportunities they present during periods of economic upheaval in the USA. Furthermore, our findings indicate that the response of credit markets to uncertainty shocks mirrors the behavior of REIT returns, albeit to a lesser degree. This discovery implies that, while housing markets and credit are intertwined through crucial feedback mechanisms, housing markets also manifest a direct response to developments in financial uncertainty, likely via the expectations channel. © 2023, EEA.}, publisher = {Eastern Economic Journal}, title = {Financial and Macroeconomic Uncertainties and Real Estate Markets}, doi = {10.1057/s41302-023-00263-0}, author = {Gomez Gonzalez J.E. and Hirs Garzón J. and Sanin Restrepo S. and Uribe J.M.}, }@misc{10818/32748, year = {2022}, url = {http://hdl.handle.net/10818/52162}, abstract = {This article seeks to identify the presence of internal strategic factors in accommodation and lodging establishments in the province of Sabana Centro in the department of Cundinamarca, Colombia.

Se encuestó a un total de 293 gerentes de igual número de medianas y grandes empresas de diferentes sectores económicos de Colombia mediante técnicas de muestreo no probabilístico. Luego, la información se analizó mediante un Modelo de Ecuaciones Estructurales. Los resultados muestran que la innovación juega un papel positivo muy limitado en la relación entre la sostenibilidad empresarial y el desempeño organizacional de las empresas.

Design/methodology/approach We use a monthly panel of 51 commercial banks for the period 1996:4–2014:8. Findings An increase in the monetary policy interest rate significantly reduces bank loan growth. The magnitude of this effect depends on banks’ financial structure. Additionally, we identify an asymmetric effect in which the bank lending channel is stronger in monetary contractions than during expansions. We show that this behavior is due to the heterogeneous response of banks with different levels of solvency. This finding has important implications for the design and implementation of monetary policy and coordination of central bank’s policy with key economic agents. Practical implications The fact that the BLC is stronger in times of monetary contraction is quite interesting for central banking, as it shows that monetary policy transmission is harder during macroeconomic downturns. When investment plans are depressed, monetary stimulus may prove insufficient to reactivate credit demand. This has proven to be true in advanced economies after a strong recession and our results suggest that is also true in emerging market economies for economic downturns in general. Central banks may have to provide stronger shocks to reactivate private credit when the economy is facing a slow economic recovery. Originality/value Our findings point out that an increase in the monetary policy interest rate significantly reduces bank loan growth. However, the magnitude of this effect critically depends on two aspects. First, bank heterogeneity matters. Particularly, the loan supply of better capitalized banks is less sensitive to monetary policy shocks. Second, the response of credit supply to shifts in short-term interest rates critically depends on the monetary policy stance. The BLC is stronger in times of monetary contraction than during expansions. Moreover, we show that this asymmetric behavior is due to the heterogeneous response of banks with different levels of solvency to the monetary policy stance.}, abstract = {Objetivo Este artículo prueba el impacto de la estructura financiera de los bancos en el canal de crédito bancario de transmisión de la política monetaria en Colombia. Diseño/metodología/enfoque Usamos un panel mensual de 51 bancos comerciales para el período 1996:4–2014:8. Recomendaciones Un aumento en la tasa de interés de política monetaria reduce significativamente el crecimiento del crédito bancario. La magnitud de este efecto depende de la estructura financiera de los bancos. Además, identificamos un efecto asimétrico en el que el canal de crédito bancario es más fuerte en las contracciones monetarias que durante las expansiones. Mostramos que este comportamiento se debe a la respuesta heterogénea de los bancos con diferentes niveles de solvencia. Este hallazgo tiene implicaciones importantes para el diseño e implementación de la política monetaria y la coordinación de la política del banco central con agentes económicos clave. Implicaciones prácticas El hecho de que la BLC sea más fuerte en tiempos de contracción monetaria es bastante interesante para la banca central, ya que muestra que la transmisión de la política monetaria es más difícil durante las recesiones macroeconómicas. Cuando los planes de inversión están deprimidos, el estímulo monetario puede resultar insuficiente para reactivar la demanda de crédito. Esto ha demostrado ser cierto en las economías avanzadas después de una fuerte recesión y nuestros resultados sugieren que también es cierto en las economías de mercados emergentes para las recesiones económicas en general. Es posible que los bancos centrales tengan que proporcionar choques más fuertes para reactivar el crédito privado cuando la economía se enfrenta a una recuperación económica lenta. Originalidad/valor Nuestros hallazgos señalan que un aumento en la tasa de interés de política monetaria reduce significativamente el crecimiento del crédito bancario. Sin embargo, la magnitud de este efecto depende críticamente de dos aspectos. En primer lugar, la heterogeneidad bancaria importa. En particular, la oferta de préstamos de los bancos mejor capitalizados es menos sensible a los choques de política monetaria. En segundo lugar, la respuesta de la oferta de crédito a los cambios en las tasas de interés a corto plazo depende de manera crítica de la orientación de la política monetaria. El BLC es más fuerte en tiempos de contracción monetaria que durante las expansiones.

In Experiment 2, eye movements were recorded while the participants viewed differently-sized (small, medium, and large) objects with the same three indentation positions tested in Experiment 1, together with a control object lacking any indentation. The results revealed that irrespective of the location of the indentation, the participants tended to grasp the mid-region of the object, with their index finger always positioned slightly above its midpoint. Importantly, the first visual fixation tended to fall in the cap region of the novel object. The participants also fixated for longer in this region. Furthermore, participants saccaded more often, as well saccading more rapidly when directing their gaze to the upper region of the objects that they were required to inspect visually.

To decrease the negative impact of these issues, different methods have been traditionally implemented. On the one hand, the location of urban consolidation Centers (UCCs) near a city can be used to consolidate freight delivery services. Therefore, the number of trucks moving in urban areas can be reduced. On the other hand, Horizontal Cooperation can also help to reduce environmental impact while increasing service level. This paper combines both strategies, that is, we deal with the location of UCCs and, simultaneously, we analyze different scenarios where the players of different supply chain processes exhibit various levels of cooperation. Thus, different levels of cooperations regarding routing and UCCs-location decisions are considered in the following scenarios: (a) non-cooperative case, in which all decisions are decentralized (i.e., each enterprise solves its own vehicle routing problem); (b) low-cooperative case, where depot capacities are shared but the customers are still being served by each company's fleet of vehicles; (c) semi-cooperative case, based on centralized route planning decisions (i.e. facilities and fleets are shared among participating enterprises); and (d) fully cooperative scenario, where the routing plans and facility-location decisions are taken by consensus amongst all the participants. In order to estimate the benefits of both strategies, we propose a flexible metaheuristic algorithm to deal with the combined location and routing problem under the different cooperative scenarios.

Theoretical literature suggests a positive relationship between financial openness and growth, development, and stability, but empirical studies reveal conflicting evidence. This paper examines these contradictions by analyzing data from 58 countries between 2010 and 2020. Using various measures for financial openness and stability, and a double debiased machine learning (DDML) model to control for confounders, we find that financial openness generally enhances banking stability, evidenced by lower nonperforming loan ratios, higher capital adequacy ratios, and increased bank liquidity.

However, inefficient routes are not only more expensive for the shipper but they are also more carbon-intensive. In this context, and from an operative level, we analyze the environmental impact of inbound logistics caused by fast shipping. We create a discrete-event simulation model to understand and compare the effect that certain parameters (i.e., delivery windows, inventory management policies, truck type) have on sustainability inbound logistics. We validate this model with the largest retailer in Mexico in order to analyze how sustainable fast shipping actually is and how to reduce its environmental impact.

In this sense, this research aims to study the impacts of consumers' ethical perceptions on companies, and how this perception affects the development of the consumer-brand relationship, integrating attitudinal, conative, and behavioral elements. Method: A survey was carried out with 538 questionnaires, analyzed through structural equations, with the reference market of manufacturers of cellular devices (smartphones). Main Result: The consumer's ethical perception demonstrated contributions in the development of the consumer-brand relationship, under the attitudinal, conative, and action aspects. At an attitudinal level, the greatest impact of PEC is on consumer confidence. The total effects of PEC on behavioral intentions were consistent and relatively high, showing a strong relationship with loyalty, purchase intention, and brand value. Contributions: We describe how the PEC affects the development of the consumer-brand relationship in a chain that represents its evolution, integrating the attitudinal, connective components of action, suggesting a central role of consumers' ethical perception in brand management. The model explained 79.2% of loyalty and 74.1% of purchase intent in the development structure of the consumer-brand relationship, based on the impact of ethical perceptions.

We found that SW and BT positively influence CP, with BT having the greater influence, and economic activity moderated these relationships. Consequently, we show that manufacturing companies use SW the most, while service companies tend towards BT. No significant differences were found in the multigroup analysis by type of industry. However, there was a positive association between CP and SW only for commercialization companies, which means that these are increasingly making inroads into using SW.

It also broadens the understanding of Industry 4.0 (I4.0) technologies and their impact on the CP of companies in emerging economies. © 2023 The Authors}, abstract = {Este estudio analiza las relaciones de trabajo inteligente (SW) en grandes y medianas empresas de Ecuador, Colombia y Perú en términos de tecnologías base (BT) y desempeño corporativo (CP). Se recogieron un total de 431 encuestas a trabajadores de diferentes niveles jerárquicos y el procesamiento de los datos se realizó mediante el Modelo de Ecuaciones Estructurales (SEM) y el Análisis Multigrupo. Encontramos que SW y BT influyen positivamente en CP, siendo BT la mayor influencia, y la actividad económica moderó estas relaciones. En consecuencia, mostramos que las empresas manufactureras son las que más utilizan SW, mientras que las empresas de servicios tienden a BT. No se encontraron diferencias significativas en el análisis multigrupo por tipo de industria. Sin embargo, hubo una asociación positiva entre CP y SW sólo para las empresas de comercialización, lo que significa que estas están incursionando cada vez más en el uso de SW. Este artículo reconoce las contribuciones de estudios previos y es el primero en proporcionar a investigadores, profesionales y académicos evidencia empírica sobre SW, BT y CP. También amplía la comprensión de las tecnologías de la Industria 4.0 (I4.0) y su impacto en el PC de las empresas de las economías emergentes. © 2023 Los Autores}, publisher = {Asia Pacific Management Review}, title = {Smart working and base technologies in corporate performance: New directions in emerging firms}, title = {Trabajo inteligente y tecnologías de base en el desempeño corporativo: nuevos rumbos en las empresas emergentes}, doi = {10.1016/j.apmrv.2022.12.008}, author = {Aguilar-Rodríguez, Iliana E. and Bernal-Torres, César A. and Artieda-Cajilema, Carlos Hernán and Tapia-Andino, Geovanni F.}, }@misc{10818/32748, year = {2024}, url = {http://hdl.handle.net/10818/61883}, abstract = {The data presented in this article is generated by a steady-state simulation for performing a techno-economic assessment for comparing three electrolysis technologies in the PtM context.

In the experiments reported here the participant's tongue was stimulated while they looked at a mirrored dummy tongue. On average, the participants agreed with the statement that they felt as if they had been touched in the location where they saw the rubber tongue being touched (experiment 1), thus demonstrating visual capture. When the external tongue was illuminated with a laser pointer (experiment 2), a significant proportion of the participants reported feeling either tactile or thermal stimulation on their own tongue. These results therefore demonstrate that the multisensory integration of visual, tactile, and proprioceptive information that gives rise to the RHI can be extended to the tongue (a body part that is rarely seen directly).}, publisher = {Perception}, title = {The Butcher's Tongue Illusion}, doi = {10.1068/p7733}, author = {Charles, Michel and Velasco, Carlos and Salgado Montejo, Alejandro}, }@misc{10818/32748, year = {2009}, month = {1}, url = {http://hdl.handle.net/10818/48742}, abstract = {Nowadays, productivity and ergonomic reasons impose the use of Automated Material Handling Systems (AMHS) to transfer work-in-process within modern semiconductor factories.
