External knowledge search,absorptive capacity and radical innovation in high-technology firms

Open innovation and absorptive capacity are two concepts based on the idea that companies can leverage the knowledge generated externally to improve their innovation performance. The aim of this paper is to analyse the joint effect of open innovation and absorptive capacity on a firm's radical innovation. Open innovation is expressed in terms of external search breadth and depth strategies and absorptive capacity is described by distinguishing between potential and realized absorptive capacity. In order to test our hypotheses, we carried out empirical research in firms operating in high-technology industries. The results indicate that internal routines and processes for absorbing external knowledge help explain radical innovation as they show a significant effect of potential and realized absorptive capacity. Also, there is a moderating effect of absorptive capacity on open innovation. Specifically, potential absorptive capacity exerts a positive effect on the relationship between external search breadth and depth and radical innovation. Realized absorptive capacity moderates the influence of external search breadth. These findings confirm the complementary nature of absorptive capacity and open innovation search strategies on radical innovation.     

Graphical and Numerical Methods for Detecting Influential Observations in Complex Bingham Data

We describe methods to detect influential observations in a sample of pre-shapes when the underlying distribution is assumed to be complex Bingham. One of these methods is based on Cook's distance, which is derived from the likelihood of the complex Bingham distribution. Other method is related to the tangent space, which is based on the local influence for the multivariate normal distribution. A method to detect outliers is also explained. The application of the methods is illustrated in both a real dataset and a simulated sample.     

Adolescent Bullying and Weapon Carrying: A Longitudinal Investigation

Using four data waves from an ongoing longitudinal study, we examined the longitudinal association between weapon carrying and bullying (i.e., bully, victim, bully‐victim). Participants were 1,042 adolescents (55.9% female) recruited from Texas high schools, including Hispanic (31.7%), White (30.3%), African American (26.6%), and other (11.4%) with a mean age of 15.1 years at baseline. Multivariate logistic regression revealed that only baseline bully‐victim was linked to weapon carrying and only 1 year later (Adjusted odds ratio = 1.76, 95% confidence interval: 1.08, 2.85), after controlling for baseline weapon carrying, age, gender, race, and parent education. No significant longitudinal association was found with bully or victim. Findings emphasize the importance of interventions targeting both bullying perpetrators and victims, while also highlighting the necessity of longitudinal research.     

An Intercultural Competence Model of Strategic Public Relations Management in the Peru Mining Industry Context

This study develops and tests an intercultural competence model of strategic public relations management in the Peruvian mining industry. The model proposes that public relations practitioners' trait-level intercultural competence (empathy, open-mindedness, and flexibility) affect their perceptual-level competence (anxiety and uncertainty management), which in turn influence their behavioral-level competence (public relations practices) and the consequent relational quality with the publics. Structural equal modeling was used to analyze the data from 90 practitioners with rich intercultural public relations experiences. Results indicated that trait competence components worked differently in reducing practitioners' uncertainty and anxiety. Such distress reduction enhanced the use of symmetrical and two-way public relations. Finally, symmetrical public relations and lowered anxiety increased practitioners' perceptions of trust and control mutuality in the relationships their organizations had with the publics. The model's theoretical and practical implications are discussed.     

Are Spontaneous Expressions and Emotions Linked? an Experimental Test of Coherence

We measured facial behaviors shown by participants in a laboratory study in which a film was used to elicit intense emotions. Participants provided subjective reports of their emotions and their faces were recorded by a concealed camera. We did not find the coherence claimed by other authors (e.g., Rosenberg & Ekman, 1994) between the displayed facial expressions and subjective reports of emotion. We thus concluded that certain emotions are not a necessary or sufficient precondition of certain spontaneous expressions.     

Sustainability Ranking for Cuban Tourist Destinations Based on Composite Indexes

This investigation approaches the levels and the predictors of loneliness among migrant youths from returned migrant families from France to Portugal. Three research questions guided the study: (1) Does loneliness of migrant youths differ from those who have never migrated? (2) Are migrant youths’ re-acculturation factors related to their loneliness? (3) Is the adaptation of migrant youths linked to their loneliness? The answer to these questions is important to improve migrant youths’ re-acculturation experiences and their adaptation. The sample included 222 youths from returned migrant families from France. Participants completed the brief Portuguese version of the Revised UCLA Loneliness Scale (ULS-6), in addition to measures of re-acculturation and adaptation. A control group comprised of 211 Portuguese adolescents who have never migrated was also involved in the investigation. Youths from returned migrant families showed lower levels of loneliness than their native Portuguese counterparts who have never migrated. Demographic, re-acculturation, and adaptation factors were significantly related to adolescents’ loneliness. Major predictors of loneliness were age at return, contacts with peers without migratory experience, perceived discrimination, stressful adaptation experience, and satisfaction with life.     

Guerrillera Editorship enacts the decolonial imaginary of Chicana editors

This project examines the editorial practices of former Chicana editors of a bilingual, alternative, activist Chicana/Chicano college student newspaper, mapping out the ways Chicana feminist epistemologies shaped their editorial praxis. Grounded in the decolonial imaginary of seven Chicanas, we identify a praxis we call Guerrillera Editorship in which Chicana editors integrate their leadership, advocacy, and written work within a muxerista orientation in order to work communally to honor the testimonio of contributors, strive towards social justice, and draw attention to Chicana issues. This work enhances an existing scholarly record that analyzes the rhetoric of Chicana feminists, but lacks an analysis of Chicana-led media production. By contextualizing the efforts of these contemporary Chicana cultural workers within the history of Chicana feminist print media, and drawing on Chicana feminist theories to guide the methodology and analysis of this project, we offer a Chicana-centered editorial activism whose decolonial underpinnings counter masculinist leadership styles and offset mainstream editorial practices.     

El tema de la pregunta y la elaboración de las respuestas en la detección de mentiras

Resumen

En este trabajo se estudió la incidencia que, sobre la detección de mentiras, podría tener que los temas a que estaban referidas variasen en cuanto a implicación emocional para el emisor y que las respuestas fuesen preparadas o espontáneas. Los resultados obtenidos señalaron que la implicación personal en el tema facilita el reconocimiento de las respuestas falsas, a la vez que la preparación previa de las respuestas dificulta la detección de mentiras a jueces no entrenados.     

The development of global IT infrastructure

A research model of the impact of a multinational corporations’ (MNC) global strategic orientation on global IT infrastructure was developed using global integration, or the degree to which a global strategy is actually implemented, as a mediator. A “matched pair” survey of 94 MNCs was conducted (two respondents per firm) in order to guard against common source bias. The results showed that the firms that pursue a globally oriented strategy actually enacted these strategies as indicated by a wide-variety of resource flows across national units. The role of the level of global integration as a mediator between global strategic orientation and global IT capabilities was empirically demonstrated. This confirms that a global strategy is not sufficient to ensure that an enabling IT infrastructure will be developed; rather it is the actual level of integration and interdependence that is achieved as a result of the strategy that drives IT infrastructure. The primary areas in which global integration was found to be closely linked to the global IT infrastructure were human resources, which significantly influenced the reach, range, support services and planning of the global IT infrastructure, and information resources which significantly influenced the planning dimension of the infrastructure. These results strongly suggest that the transfer of people among national units creates an information needs “pull” which leads to the development of better IT infrastructure and that the “push” of standardized information also contributes positively.
