Abstract
Purpose
The purpose of this paper is to analyze the impact of the torque, power, jerk and energy consumed constraints on the generation of minimum time collision‐free trajectories for industrial robots in a complex environment.
Design/methodology/approach
An algorithm is presented in which the trajectory is generated under real working constraints (specifically torque, power, jerk and energy consumed). It also takes into account the presence of obstacles (to avoid collisions) and the dynamics of the robotic system. The method solves an optimization problem to find the minimum time trajectory to perform the tasks the robot should do.
Findings
Important conclusions have been reached when solving the trajectory planning problem related to the value of the torque, power, jerk and energy consumed and the relationship between them, therefore enabling the user to choose the most efficient way of working depending on which parameter he is most interested in optimizing. From the examples solved the authors have found the relationship between the maximum and minimum values of the parameters studied.
Research limitations/implications
This new approach tries to model the real behaviour of the actuators in order to be able to upgrade the trajectory quality, so a lot of work has to be done in this field.
Practical implications
The algorithm solves the trajectory planning problem for any industrial robot and the real characteristics of the actuators are taken into account, which is essential to improve the performance of it.
Originality/value
This new tool enables the performance of the robot to be improved by combining adequately the values of the mentioned parameters (torque, power, jerk and consumed energy).

Abstract
The purpose of this article is to provide organized, synthesized information related to initiatives throughout the world based on knowledge‐based development (KBD) such as knowledge cities (KCs), knowledge regions, and knowledge countries. A first search was conducted using the Internet and specialized databases under the keywords “knowledge cities”. The information compiled led to other related keywords which branched out the search. All resulting information was then collated and integrated into a number of categories all unified under the field of knowledge‐based development. A compilation of information on the topic “knowledge cities” and other topics related to knowledge‐based development. The information is presented in eight sections: a glossary of KC‐related terms, a list of knowledge‐based development initiatives, a list of associations and organizations related to the topic, a list of urban KBD‐related value dimensions and their indicators, a list of international rankings, a list of special editions on KCs, a bibliography, and a directory of related sites on the Internet. This effort resulted in a public service available at the World Wide Web. The information included in this compilation is limited mainly to public domain information available throughout Internet in both English and Spanish, as well as in selected databases.

Abstract
Purpose
The aim of this paper is to disentangle the contemporaneous and non-contemporaneous relationship between regional business cycles and manufacturing productivity in a developing country, namely Colombia.
Design/methodology/approach
The methodology is quantitative. To deal with the problems of endogeneity in the production function and with the law motion of productivity (the Markov process), the authors obtain Total Factor Productivity (TFP) through the Wooldridge’s two equations system that can be jointly estimated under the generalized method of moments framework (GMM). Secondly, to avoid bias we estimate regional business cycles through the Kalman filter. Subsequently, we implement an instrumental variables/generalized method of moments regression (IV/GMM) to capture the contemporaneous and endogenous TFP–GDP cycles’ linkage at the regional level. Lastly, to deal with the non-contemporaneous link, the authors estimate a vector autoregressive model with exogenous variables (VARX) for each region. We also present the corresponding impulse–response functions.
Findings
The authors’ general results suggest a remarkable causality, both contemporary and non-contemporary, from productivity to GDP (but not vice versa) in the most developed regions of the country. This implied productivity could influence in the economic growth of regions in short and long runs. These results are different than those expected by economic theory and should be considered by local economic policy makers.
Research limitations/implications
The authors consider that a more detailed analysis should be carried out at the level of each sector within the manufacturing industry to further clarify these findings.
Practical implications
The policy should be oriented to obtaining cutting-edge technologies through subsidies, and also should facilitate the access to financial capital and the investment in R&D laboratories. On the other hand, the link with international trade also must be reinforced because the importing of intermediate inputs and exporting of output allow the firms to obtain embodied technologies, also to incur on learning by exporting and importing processes and finally to gain experience and competitiveness in foreign markets.
Social implications
The causality in the region that provides more than 50% of economic activity within the country (Third region) is only in one directional, from TFP towards gross domestic product (GDP) and not vice versa. As the influence from GDP towards TFP is minimal in the remaining regions, the manufacturing productivity influences both short and long run regional economic growth in Colombia. This implies that economic policy at the level of macro-region must be modified; the government should give additional support to the manufacturing sector, especially in developed regions and for the small and medium-sized enterprises (SMEs) (wich represent 92% of manufacturing firms) to increase economic growth in the future.
Originality/value
The authors’ contribution is threefold. First, they pay special attention to the contemporaneous cyclical relationship (i.e. pro-cyclical, counter-cyclical or acyclic) and the non-contemporaneous causality with productivity. Second, they estimate productivity with the GMM two equation system considering an endogenous Markov process. Third, to the best of their knowledge, at least in the case of Latin America, there are no studies in this direction combining these statistic methods, including that of Colombia.

Abstract
Purpose – Despite an abundance of literature on the effects of copyright infringement on music consumption, empirical evidence remains ambiguous. The aim of this chapter is to quantify the effect of copyright infringement on recorded music purchases and live music attendance for Spanish frequent music consumers, and to measure its effect on participation for all music consumers.
Design/methodology approach – We rely on survey data for the Spanish population as our main information source and use propensity score matching to estimate the average effect of copyright infringement on music consumption. In order to do so, the methodology aims at estimating the difference between actual outcomes (record purchases or attendance to live concerts) for copyright infringers and the (counterfactual) outcome would they had not been infringers.
Findings – Two findings stand out. First, and with regards to recorded music consumption, we find a net positive effect of copyright infringement on full album purchases although a nonsignificant one for tracks. Second, there is a positive and significant effect on live attendance, which is consistent with an indirect appropriation effect across products. These results are robust when participation is considered, but some interesting differences arise between recorded music purchasers and live concerts attenders.
Originality/value – First, the use of a counterfactual control group provides an additional approach to the assessment of copyright infringement. Second, within the same framework we investigate the effects of copyright infringement on recorded and live music, an approach that sheds some light on the degree of complementarity between both markets.

This paper aims to analyze the relationship between watching dance and mood enhancement considering potential differences across gender and age brackets.
Abstract
Purpose
This paper aims to analyze the relationship between watching dance and mood enhancement considering potential differences across gender and age brackets.
Design/methodology/approach
Exploratory research was undertaken through a personal survey, using a structured questionnaire on a large sample of young participants between 18 and 35 years old, split into generational cohorts (Millennials or Generation Y and Centennials or Generation Z). Quota sampling (gender and age) was the method used to select respondents.
Findings
Results show that after watching dance, more positive mood changes were observed in general. However, they were stronger among women and younger Millennials. These findings are important as they open a new area of study; show the effects of culture on people; and help design programming strategies to enlarge audiences.
Originality/value
The effects of specific forms of arts and cultural participation on people’s moods have been analyzed from a diversity of disciplines. In the case of dance, studies have tested this relation among practitioners (active participants) but not among viewers (attendees) as this paper does.

The purpose of this paper is to carry out a meta-regression analysis upon the literature that examines the relationship between family firms and financial performance.
Abstract
Purpose
The purpose of this paper is to carry out a meta-regression analysis upon the literature that examines the relationship between family firms and financial performance.
Design/Methodology/Approach
Information of publication and study characteristics from 61 primary studies, comprising 726 size effects was collected. In particular, three leading factors highlighted in narrative literature reviews analyzed were: the financial performance measures, the family–firm definitions and the estimation methodologies.
Findings
Overall, a positive relationship between family involvement and financial performance was found. A series of results, those linked to return on assets (ROA) – earnings before interest, taxes, depreciation and amortization (EBITDA), suggest positive publication bias from family definition and negative publication bias when OLS is used. Tobin’s Q estimates show no linkage to certain traits and aspects of the research process.
Originality/value
Existing literature review and meta-analysis studies show not concluding results on the family effect upon firm performance. The meta-regression analysis used in this paper allows to examine simultaneously effect size and publication bias. The latter effect is particularly salient in the approach and findings, and not present in previous studies.
Propósito
Llevar a cabo un análisis de meta-regresión a la literatura que examina la relación entre firmas familiares y desempeño financiero.
Diseño/metodología/aproximación
Se usa la información de la publicación y características del estudio de 61 estudios primarios, que incluyen 726 estimaciones. Se examinan tres elementos principales de esta literatura: (i) medidas de desempeño financiero, (ii) definición de firma familiar, y (iii) metodología de estimación.
Resultados
Se establece una relación positiva entre involucramiento familiar y desempeño financiero. Las estimaciones que examinan ROA-EBITDA sugieren sesgo positivo de publicación. Las estimaciones que utilizan estimación de Mínimos Cuadrados Ordinarios sugieren un sesgo negativo de publicación. Las estimaciones que examinan la Q de Tobin, no sugieren relación con las características de los estudios o de la investigación.
Originalidad/valor
Los estudios de meta-análisis existentes sobre esta literatura no ofrecen resultados concluyentes del efecto de las firmas familiares y desempeño financiero. El método de meta-regresión permite examinar simultáneamente el efecto entre las variables y la posible existencia de sesgo de publicación. La indagación de este último es de particular interés y no se encuentra en otros estudios.

Abstract
Purpose
This study investigates the impact of top management’s networking capabilities on the organizational networking and absorptive capacities of small and medium-sized enterprises (SMEs) in Puerto Rico. This study aims to enhance understanding of how top management influences the networking behaviors that drive SME performance.
Design/methodology/approach
Data were collected from Puerto Rican SMEs and analyzed using multi-item reflective indicators on a five-point Likert scale. Partial least squares structural equation modeling was used to test the hypotheses and explore relationships between networking capabilities and absorptive capacities.
Findings
The study finds that top management’s networking capabilities are predominantly reactive, significantly impacting information acquisition, opportunity enabling and weak-tie resource mobilization. Both potential and realized absorptive capacities are critical for SMEs to leverage resources for competitive advantage.
Research limitations/implications
Further research is needed to explore how these findings apply to other regions or industries and expand on the role of proactive networking in enhancing SME competitiveness.
Practical implications
The study underscores the importance of refining proactive and reactive networking capabilities to sustain competitive advantage in dynamic environments.
Social implications
Puerto Rico’s unique economic context, including natural disasters and economic downturns, makes the findings relevant for SMEs in similar regions that rely on strong networks for resilience.
Originality/value
This research contributes to the dynamic capabilities literature by confirming SMEs’ proactive and reactive networking dimensions. It also offers a unique perspective by focusing on Puerto Rican SMEs facing distinct economic and social challenges.
Objetivo

Abstract
Purpose
This paper aims to explore the position of women in the communication management sector in Spain from their own experiences. The study examines female communication and leadership styles, emphasising the cost of leadership in which they are leaders or led.
Design/methodology/approach
This study used a qualitative methodology based on in-depth interviews with 22 women actively working in top companies and agencies: female communication directors, female employees with a female leader and female employees with a male leader. Data were analysed through thematic analysis.
Findings
Results show mixed communication and leadership styles. In addition, the high level of self-demand of female communication managers stands out, making it challenging to achieve a work-life balance and the implementation of successful role models.
Social implications
Exploring the factors of female leadership remains necessary to understand and make their situation in various industries and positions visible. It also helps remove barriers to leadership, guide organisations in addressing gender discrimination issues and develop mechanisms for the internal promotion of female professionals.
Originality/value
To the best of authors' knowledge, this is the first study exploring the leadership and communication styles of women in the Spanish Public Relations (PR) and communication management industries. It also highlights the aspects influencing the cost of leadership.
