Facial expression recognition by human observers is affected by subjective components. Indeed there is no ground truth. We have developed Discrete Choice Models (DCM) to capture the human perception of facial expressions. In a first step, the static case is treated, that is modelling perception of facial images. Image information is extracted using a computer vision tool called Active Appearance Model (AAM). DCMs attributes are based on the Facial Action Coding System (FACS), Expression Descriptive Units (EDUs) and outputs of AAM. Some behavioural data have been collected using an Internet survey, where respondents are asked to label facial images from the Cohn–Kanade database with expressions. Different models were estimated by likelihood maximization using the obtained data. In a second step, the proposed static discrete choice framework is extended to the dynamic case, which considers facial video instead of images. The model theory is described and another Internet survey is currently conducted in order to obtain expressions labels on videos. In this second Internet survey, videos come from the Cohn–Kanade database and the Facial Expressions and Emotions Database (FEED).

The purpose of the paper is to shed light on the output of project management (PM) dynamic capabilities Specifically, the study investigates what effect PM dynamic capabilities have on company performance, both directly and indirectly, through the mediation effect of project and portfolio performance. Additionally, it tests whether program performance might also mediate the relationship.

The hypotheses were tested using partial least squares with a sample of 63 international firms that engage in projects globally.

The main finding of this research is that PM dynamic capabilities do not influence firm performance directly but do so indirectly by increasing firms' performance in projects, programs and portfolios. Both project and portfolio performance have a mediation effect on the relationship between dynamic capabilities and firm performance, but portfolio performance absorbs all this effect when the two performances are in the model.

This paper sheds light on the link between dynamic capabilities and firm performance. It tests the real outcome of dynamic capabilities by making an explicit distinction between firm performance at three intermediate levels (project, program and portfolio) and overall firm performance. Moreover, it opens the black box of dynamic capabilities and empirically operationalizes the theoretical model of sensing-seizing-transforming as the three constituting routines of dynamic capabilities.

Rectangular conductors play an important role in planar transmission line structures, multiconductor transmission lines, in power transmission and distribution systems, LCL filters, transformers, industrial busbars, MEMs devices, among many others. The precise determination of the inductance of such conductors is necessary for their design and optimization, but no explicit solution for the AC resistance and internal inductances per-unit length of a linear conductor with a rectangular cross-section has been found, so numerical methods must be used. The purpose of this paper is to introduce the use of a novel numerical technique, the proper generalized decomposition (PGD), for the calculation of DC and AC internal inductances of rectangular conductors.

The PGD approach is used to obtain numerically the internal inductance of a conductor with circular cross-section and with rectangular cross-section, both under DC and AC conditions, using a separated representation of the magnetic vector potential in a 2D domain. The results are compared with the analytical and approximate expressions available in the technical literature, with an excellent concordance.

The PGD uses simple one-dimensional meshes, one per dimension, so the use of computational resources is very low, and the simulation speed is very high. Besides, the application of the PGD to conductors with rectangular cross-section is particularly advantageous, because rectangular shapes can be represented with a very few number of independent terms, which makes the code very simple and compact. Finally, a key advantage of the PGD is that some parameters of the numerical model can be considered as additional dimensions. In this paper, the frequency has been considered as an additional dimension, and the internal inductance of a rectangular conductor has been computed for the whole range of frequencies desired using a single numerical simulation.

The proposed approach may be applied to the optimization of electrical conductors used in power systems, to solve EMC problems, to the evaluation of partial inductances of wires, etc. Nevertheless, it cannot be applied, as presented in this work, to 3D complex shapes, as, for example, an arrangement of layers of helically stranded wires.

The PGD is a promising new numerical procedure that has been applied successfully in different fields. In this paper, this novel technique is applied to find the DC and AC internal inductance of a conductor with rectangular cross-section, using very dense and large one-dimensional meshes. The proposed method requires very limited memory resources, is very fast, can be programmed using a very simple code, and gives the value of the AC inductance for a complete range of frequencies in a single simulation. The proposed approach can be extended to arbitrary conductor shapes and complex multiconductor lines to further exploit the advantages of the PGD.

For decades, the Altiplano farmers of Bolivia had been marginalized by the remoteness of their home and exploitation by the private sector and injustices inflicted by the government. The notion that this impoverished region could sustain economic development might correctly have been described as hopeless. The Altiplano farmers’ inability to develop a sustainable source of income threatened their very cultural identity. The only manner in which the farmers’ culture might be sustained was through charitable donations from international NGOs. But it is exactly in this situation, when obstacles are stacked against success, where appreciative intelligence can provide an avenue to overcome despair. After years of working with NGOs, Javier Hurtado was able to identify a source of value that could provide hope and a path to sustainable development for the Altiplano farmers. This is the story of the impact that one individual's application of appreciative intelligence can have on a community. The Irupana story illustrates how our destinies are shaped by our ability to discover that which is best within ourselves and the communities in which we live. This is the story of Javier Hurtado and Martha Cordero, founders of Irupana Organic Foods located in the Bolivian Altiplano, as they discover the unique potential in the harsh Bolivian landscape and the impoverished peasant farmers that inhabit this setting. Through the framework of appreciative intelligence, the researchers observed the entrepreneurs reframe their circumstances around the positive potential that is within the Altiplano-farming community and its unique natural resources, and create a successful organic foods company.

This paper investigates the impact of green technological distance (GTD) – environmental technological knowledge distance between the firm and the industry – on the adoption of proactive and reactive environmental strategies and whether this relationship is moderated by different manifestations of green structural capital, i.e. environmental incentives, senior environmental responsibilities and external environmental communication.

The empirical analysis is conducted on a sample of 202 manufacturing companies from Spain. Hierarchical regression analysis was used to examine the moderating effect of green structural capital.

Results show that the role of green structural capital as guiding factor of the environmental response of the firm and organizational support to cope with the GTD between the firm and the industry is diverse and depends on the manifestation of green structural capital under analysis. The establishment of environmental incentives for managers and the presence of environmental information in the firm's external communications – as two expressions of green structural capital – show a different behavior when facing the environmental technological challenge, supporting environmental reactive and proactive strategies respectively. In addition, GTD increases the adoption of reactive environmental strategies, while it has no direct effect on the implementation of proactive environmental practices.

Using the novel construct of GTD and the analysis of a so far unstudied interaction, the study contributes to the literature on intellectual capital and environmental strategy considering the technical change associated to the environmental challenge. In so doing, it improves the understanding of the role of green structural capital as a guiding factor of the environmental response of the firm and organizational support to cope with the GTD between the firm and the industry.

This article aims to report on the development and validation of a bribery measurement index for the business sector, which, based on institutional theory, seeks to overcome the limitations of traditional measurements, recognizing the dynamics that originate the phenomenon and identifying process components.

To construct the index, correlational and principal component analysis techniques were used, as well as rigorous statistical tests, validating the instrument in a sample of 2,963 companies in Latin America, including Argentina, Colombia, Chile, Ecuador, Guatemala, Mexico and Peru.

The result was an instrument composed of two dimensions: (1) anti-bribery game rules, composed of regulations knowledge and anti-bribery efforts, and (2) bribery as a perceived habit, allowing an objective representation of reality due to its internal consistency, concurrent and discriminant validity.

This instrument is one of the few that focuses on measuring bribery in the business sector in terms of corrupt practices, applicable for both public and private institutions to promote game rules against bribery. Additionally, the proposed theoretical model can be used to measure other phenomena with similar characteristics.

This article empirically highlights different variables that make bribery possible. The results can be helpful in the design of strategies to prevent this type of behavior. It also highlights the importance of designing mechanisms to record information related to bribery and the different expressions of corruption in order to explain its different nuances.

Este artículo pone en evidencia empírica diferentes variables que hacen posible el soborno. Los resultados pueden ser útiles en el diseño de estrategias para prevenir este tipo comportamiento, también destaca la importancia de diseñar mecanismos para registrar la información relacionada con la lucha contra el soborno.

Este instrumento es uno de los pocos que se enfoca en medir el soborno en el sector empresarial en términos de prácticas de corrupción, útil para instituciones tanto públicas como privadas para promover mejores reglas de juego en contra del soborno. Adicionalmente el modelo teórico propuesto puede ser utilizado para medir otros fenómenos con características similares.

There is a growing interest on how critical perspectives can help us understand family businesses. Current literature suggests that critical reflection is needed in aspects such as conflict, fear, and emotions. In this chapter, we argue that the use of a critical perspective illuminates the intricate complexities of family business behavior and that a critical discussion around fear, which is conceptualized as both an inhibitor and a motivator for business, plays a significant role in the dark side of family business. To advance understanding, we review recent conversations that can help us understand better the role of fear; how does this impact on resilience? And, how do feelings and emotions impact family firms? In our review, we argue that perspectives that focus on specific tangible resources (e.g. financial) are limited to explain how families in business may deal with fear. A critical perspective suggests that three areas merit further attention: fear of failure, effects of failure, and the intersection between entrepreneurial learning and the effects of fear in the dark side of family businesses. By contextualizing critical approaches, we provide insight for researchers, policymakers, and those operating family businesses alike.
