The purpose of this paper is to introduce a three-echelon multimodal transportation problem applied to a humanitarian logistic case study that occurred in Mexico.

This study develops a methodology combining a transshipment problem and an adaptation of the multidepot heterogeneous fleet vehicle routing problem to construct a mathematical model that incorporates the use of land-based vehicles and drones. The model was applied to the case study of the Earthquake on September 19, 2017, in Mexico, using the Gurobi optimization solver.

The results ratified the relevance of the study, showing an inverse relationship between transportation costs and delivery time; on the flip side, the model performed in a shorter CPU time with medium and small instances than with large instances.

While the size of the instances limits the use of the model for big-scale problems, this approach manages to provide a good representation of a transportation network during a natural disaster using drones in the last-mile deliveries.

The present study contributes to a model that combines a vehicle routing problem with transshipment, multiple depots and a heterogeneous fleet including land-based vehicles and drones. There are multiple models present in the literature for these types of problems that incorporate the use of these transportation modes; however, to the best of the authors’ knowledge, there are still no proposals similar to this study.

This chapter discusses the connection between authentic leadership and meta competence, examining whether authentic leadership can be developed or promoted in educational processes. The authors propose the concept of shaping orientation: problem-based learning without a fixed solution but with the generation of a solution-finding approach through the process of holistic action. They posit that training in authentic leadership can be embedded in curricula if learning is problem-based. This proposition poses important research and pedagogical questions for research. Is there evidence that problem-based learning generates the leadership qualities and attitudes that the authors claim? If so, how can this relationship be reliably tested over time?

This chapter offers a dynamic model of authentic leadership that links authentic leadership to situational leadership theory and shows how dynamics in the academic environment, one of the most difficult settings that leaders face, can be addressed. Kindsiko and Vadi detail the concept of situational authenticity, which reveals how authentic leadership takes place via forms of sensing – sense-giving, sense-making, sense-breaking and sense-keeping – in work-related situations. The authors highlight questions for future research: Is sensing the key to success? Are situational ethics valid if they adapt to evolving circumstances? Are situational ethics, in effect, just another way of expressing relativism? If so, can that be reconciled with authentic leadership theory?

Researchers who work in partnership with older adults in participatory studies often experience various advantages, but also complex ethical questions or even encounter obstacles during the research process. This paper aims to provide insights into the value of an intersectional lens in participatory research to understand how power plays out within a mixed research team of academic and community co-researchers.

Four academic researchers reflected in a case-study approach in a dialogical way on two critical case examples with the most learning potential by written dialogical and via face-to-face meetings in duos or trios. This study used an intersectionality-informed analysis.

This study shows that the intersectional lens helped the authors to understand the interactions of key players in the study and their different social locations. Intersections of age, gender, ethnicity/class and professional status stood out as categories in conflict. In hindsight, forms of privilege and oppression became more apparent. The authors also understood that they reproduced traditional power dynamics within the group of co-researchers and between academic and community co-researchers that did not match their mission for horizontal relations. This study showed that academics, although they wanted to work toward social inclusion and equality, were bystanders and people who reproduced power relations at several crucial moments. This was disempowering for certain older individuals and social groups and marginalized their voices and interests.

Till now, not many scholars wrote in-depth about race- and age-related tensions in partnerships in participatory action research or related approaches, especially not about tensions in research with older people.

This paper investigates the role of economic disagreement in the cross-sectional pricing of individual stocks. Economic disagreement is quantified with ex ante measures of cross-sectional dispersion in economic forecasts from the Survey of Professional Forecasters (SPF), determining the degree of disagreement among professional forecasters over changes in economic fundamentals.

The authors introduce a broad index of economic disagreement based on the innovations in the cross-sectional dispersion of economic forecasts for output, inflation and unemployment so that the index is a shock measure that captures different aspects of disagreement over economic fundamentals and also reflects unexpected news or surprise about the state of the aggregate economy. After building the broad index of economic disagreement, the authors test out-of-sample performance of the index in predicting the cross-sectional variation in future stock returns.

Univariate portfolio analyses indicate that decile portfolios that are long in stocks with the lowest disagreement beta and short in stocks with the highest disagreement beta yield a risk-adjusted annual return of 7.2%. The results remain robust after controlling for well-known pricing effects. The results are consistent with a preference-based explanation that ambiguity-averse investors demand extra compensation to hold stocks with high disagreement risk and the investors are willing to pay high prices for stocks with large hedging benefits. The results also support the mispricing hypothesis that the high disagreement beta provides an indirect way to measure dispersed opinion and overpricing.

Most literature measures disagreement about individual stocks with the standard deviation of earnings forecasts made by financial analysts and examines the cross-sectional relation between this measure and individual stock returns. Unlike prior studies, the authors focus on disagreement about the economy instead of disagreement about earnings growth. The authors' argument is that disagreement about the economy is a major factor that would explain disagreement about stock fundamentals. The authors find that disagreement in economic forecasts does indeed have a significant impact on the cross-sectional pricing of individual stocks.

The provision of air transport services in small and regional airports is a major concern worldwide as regional aviation is challenged with inadequate revenues. This chapter aims to identify the driving factors for sustaining regional airlines and airports. Nine factors are identified through literature review and expert opinion. Fuzzy-total interpretive structural modeling is used to develop a hierarchical relationship among the factors. Truncated population of the region, national subsidies, and airport infrastructure development have been found to be the strongest drivers for promoting regional airports. This hierarchical model provides a logical structure to the factors.

This study aims to develop a conceptual model to understand how customer knowledge management (CKM) affects fitness club membership renewal through the mediation of relationship quality.

Data were collected outside of fitness clubs using a systematic sampling method. A total of 224 valid responses were collected. Structural equation modelling was used to evaluate the relationship between the constructs of the research model.

The results indicate that both knowledge from customers and knowledge for customers have a positive influence on customer satisfaction and customer trust. Among them, knowledge for customers has a stronger influence on customer satisfaction while knowledge from customers has a greater influence on customer trust. Additionally, three dimensions of relationship quality (customer satisfaction, customer trust and customer commitment) positively influence membership renewal intention with customer commitment exhibiting the greatest influence on it.

This study combines the theories of CKM and relationship quality management to explain why members will renew their service contracts. By using fitness clubs as an example, this research extends the authors' understanding of how knowledge from and for customers can influence customers' attitudes and behavioural intentions towards service companies.

This chapter addresses one of the most crucial areas for critical thinking: the morality of turbulent markets around the world. All of us are overwhelmed by such turbulent markets. Following Nassim Nicholas Taleb (2004, 2010), we distinguish between nonscalable industries (ordinary professions where income grows linearly, piecemeal or by marginal jumps) and scalable industries (extraordinary risk-prone professions where income grows in a nonlinear fashion, and by exponential jumps and fractures). Nonscalable industries generate tame and predictable markets of goods and services, while scalable industries regularly explode into behemoth virulent markets where rewards are disproportionately large compared to effort, and they are the major causes of turbulent financial markets that rock our world causing ever-widening inequities and inequalities. Part I describes both scalable and nonscalable markets in sufficient detail, including propensity of scalable industries to randomness, and the turbulent markets they create. Part II seeks understanding of moral responsibility of turbulent markets and discusses who should appropriate moral responsibility for turbulent markets and under what conditions. Part III synthesizes various theories of necessary and sufficient conditions for accepting or assigning moral responsibility. We also analyze the necessary and sufficient conditions for attribution of moral responsibility such as rationality, intentionality, autonomy or freedom, causality, accountability, and avoidability of various actors as moral agents or as moral persons. By grouping these conditions, we then derive some useful models for assigning moral responsibility to various entities such as individual executives, corporations, or joint bodies. We discuss the challenges and limitations of such models.

The purpose of this study is to compare market reactions to the change in the demand by index funds between large and small company stocks by examining the transition of the S&P 500, S&P 400 MidCap and S&P 600 SmallCap indexes from market capitalization to free-float weighting. This unique information-free event allows not only avoiding confounding information signaling and investor awareness effects but also comparing the effect of the decrease in demand on stocks of different sizes.

This study uses the event study methodology to calculate abnormal returns and trading volume around the full-float adjustment day. It also tests for significant changes in institutional ownership and liquidity. Multivariate regressions are used to examine the relation of liquidity changes and price elasticity of demand to the cumulative abnormal returns around the full-float adjustment day.

This study finds significant decreases in stock price accompanied with significant increases in trading volume on the full-float adjustment day, and significant gains in quasi-indexer institutional ownership and liquidity. The main finding is that cumulative abnormal returns around the event period are related to changes in the number of quasi-indexer and transient institutional shareholders, not to changes in liquidity or price elasticity of demand.

This study provides the first comprehensive comparison analysis of stock market reactions to the decline in demand between large and small company stocks. As an important implication for future studies of the index effect, changes in institutional ownership should be considered in the analysis.
