Researchers have studied supervisors’ proactive personality in its relationship with employees’ attitudes. However, little attention has been given to how employees react to instances of supervisors’ proactive behavior. Drawing from P-E fit theory, we propose that the relationship between supervisor weekly taking charge behavior (TCB, the quintessential proactive behavior) and employees’ weekly job attitudes depends on employees’ proactive personality.

Utilizing a diary study, we investigate how employees’ proactive personality moderates the within-person relationship between supervisor TCB and employees’ attitudes (measured as job satisfaction and affective commitment). We surveyed 39 employees ten times over ten weeks.

Multi-level analyses partially supported our predictions on the differential effects of weekly supervisor TCB on employees’ job attitudes. Supervisors’ above-average TCB was significantly related to higher levels of employees’ job satisfaction and marginally related to affective commitment for employees with high proactive personality, but not for those with low proactive personality. Supplemental analyses revealed that our results are unique to supervisor TCB and not to supervisor helping behavior.

Our study is among the first to utilize a dynamic approach to understand the consequences of supervisors’ proactive work behavior in the context of P-E fit research. Our findings will open several fruitful avenues for future research that continue to understand the powerful effects of supervisors’ proactivity.

Drawing from the emotions as social information theory, this paper aims to investigate the differential effects of emotions in inter vs intracultural negotiations.

The authors used one face-to-face negotiation and two experimental scenario studies to investigate the influence of emotions (anger vs happiness) and negotiation type (intercultural vs intracultural) on concession behavior.

Across the three studies, the results consistently show that angry opponents from a different national culture obtain larger concessions from negotiators. A face-to-face negotiation shows that happy opponents from the same culture are able to obtain larger concessions from negotiators. Additionally, the negotiator’s intentions to compromise and yield mediate the relationship between the interaction of emotions and counterpart’s culture on concessions.

Two limitations are that the studies were conducted in a single country and that they use different types of role-playing designs. The empirical implications provide evidence of the moderating effect of the counterpart’s culture on the effect of anger on concessions. Then, providing two different mechanisms for concessions.

The research helps global negotiators who face counterparts from different nationalities. It suggests that these negotiators should be mindful of their counterpart’s emotions in intercultural negotiation as anger seems to generate more concessions in this setting.

The article is among the first studies to show that the combination of the counterpart’s culture and emotions has an effect on concessions in negotiation. Compromising and yielding are mediating mechanisms for this moderated effect. As opposed to previous studies that use one type of research design, the research combines face-to-face and scenario methodologies to test the predictions.

Pulque is a fundamental piece in the Mexican gastronomy and identifying consumers’ perception could help promote it and generate new opportunities of commercialization. The purpose of this paper is twofold: first, to explore the underlying factors that influence consumers’ perception toward pulque, and second, to identify groups of consumers according to their perception.

A questionnaire was designed and applied to 220 consumers within points of sales. Exploratory factor analysis (EFA) was undertaken and hierarchical cluster analysis (HCA) was used to identify different groups of consumers.

By means of EFA three factors were obtained: traditionality, bad reputation of pulquerías and functional beverage. In order to identify different consumption patterns among consumers, HCA was performed and three groups were identified: traditional, neo-consumers and neo-consumers in transition. The groups identified showed significant differences in their perception.

Pulque has recently gained interest in various consumer sectors, mainly among young consumers, who are consuming and promoting the beverage these days. In this sense, the results of this work could be used for its promotion and consumption in order to attract more consumers and make a contribution to the development of local economies.

This is the first work in Mexico to explore the perception of consumers toward pulque: the most important traditional fermented beverage in Central México. Results of this research suggest the appearance of a revaluation process among young consumers, more informed and with greater sensitivity toward traditional Mexican food, particularly in the case of pulque. Likewise, these results could be useful for producers and sellers to carry out commercial strategies and promote the drink.

In recent decades, higher education institutions (HEIs) have increasingly adopted marketing-oriented approaches. While the adoption of marketing was slower in Europe and Spain, it has become a vital tool for HEIs, both to stay competitive in a changing socio-economic context and to face the challenges posed by the transition to the University 2.0 model. This study aims to analyse the historical evolution of communication techniques used by universities, bringing into focus the relevance of social networks in the most recent decades.

This research methodology consists of two components. Firstly, a comprehensive analysis of the available data is conducted to investigate the earliest marketing and communication actions involving universities, as well as their evolution over time, contextualizing this within the significant shifts in the social, political and technological background. Secondly, a specific focus is placed on the contribution of social media, particularly Twitter, as a powerful tool in creating a university brand and effectively promoting educational institutions, especially during the last stage of this historical evolution. To identify and analyse these trends, Natural Language Processing is used, specifically by leveraging topic modelling techniques.

The results of this analysis offer insights into the evolution of marketing communication applied by Spanish universities and show the increasing importance of social networks and the use of specific topics and contents to enhance their impact on engagement.

This study contributes to the literature by using a novel methodological approach to the research on the historical development of communication in universities in Spain, providing guidance to manage their social media strategy to differentiate themselves, increase engagement and foster brand loyalty.

The purpose of this paper is to propose a dedication-constraint-temptation (DCT) model to study the factors influencing customers’ loyalty to mobile data service (MDS) providers. The DCT model explicitly explores the important yet overlooked role of alternative attractiveness (the temptation-based mechanism) as a mediator and the boundary condition of their interrelationships (e.g. relationship length). The model also integrates new and established antecedents of customer-based brand equity (C-BBE) (the dedication-based mechanism) and switching barriers (the constraint-based mechanism).

The proposed model is tested using partial least squares–structural equation modeling with a sample of 331 MDS users.

The results indicate that C-BBE has an indirect effect on customer loyalty (via alternative attractiveness) in both relationship groups (shorter- vs longer-term). However, the indirect effect of switching barriers on customer loyalty only exists in longer established relationships. The results from multi-group analysis reveal that the effect of switching barriers on alternative attractiveness significantly differs across groups. In addition, customer value anticipation and procedural switching costs appear to be the most salient antecedents of C-BBE and switching barriers for both groups.

This study makes an incremental contribution by incorporating the temptation-based mechanism as a mediator and relationship length as a moderator into the dedication-constraint model. This study also extends the information systems and brand management literatures by demonstrating the strategic importance of customer value anticipation in the information and communication technology brand equity-building.

Based on the theory of dynamic capabilities, the purpose of this study is to examine how generation influences the effect of innovation capability on family business performance. To achieve this purpose, a moderation model is tested using the generational level as the moderating variable.

This study used a sample of 106 family businesses CEOs who were surveyed by mail using the Limesurvey 2.5 platform. The results obtained were analyzed using the second-generation partial least squares (PLS) structural equation model. The MICOM (Measurement Invariance of Composite Models) approach was used to analyze the moderating effect.

This research sheds lights on the innovation capacity to influence the family businesses performance, and on the generational level moderating this effect. As a result, the influence of the innovation capacity in second generation family businesses performance is higher than in the first generation.

This study reveals the influence that the generational level has on the effect of innovation capacity on the family business performance. A greater dispersion of ownership, more participatory decision-making, and greater CEOs commitment to leadership in second- and later-generation family businesses, are the main key drivers of this result.

In comparison to previous studies, this research provides insights into the moderating effect of the generational level on the influence of innovation capacity on the family businesses performance through the MICOM approach (Measurement Invariance of Composite Models).

The purpose of this paper is to conduct a literature review in order to understand the relationship that exists between international academic mobility (IAM) and innovation and its impact on the countries of origin, country of destination and the countries of origin and destination simultaneously of academics.

After analysing 36 articles selected from 15 top journals by way of a systematic review of the literature, the authors located 20 variables, including five related to innovation with a positive, negative or null impact on the countries.

The five innovation proxies identified were: highly qualified human capital”, “attractive research and working conditions”, “patent filing”, “publications” and “research networks”, all related to Science, Technology and Innovation. The results highlight the evidence that the different dimensions of innovation have a differentiated impact on the countries of origin and destination and in both at the same time.

Knowing the types of innovation that IAM generates enables governments to invest in scientific, technological, economic and social development to choose the best measures for attracting and retaining academics. For the industry, technological catch-up and highly skilled labour means enhancing competitiveness and capacity building, growth in Research and Development (R&D), the creation of new products, patent filing, increased investments and the expansion of internationalisation.

This paper shows that the association between IAM and innovation is differentiated for the countries. Both countries involved in the association receive a positive impact in the publications and research networks. The main impact to countries of origin is the increase of highly qualified human capital. On the other hand, the benefits for the countries of destination concern patent filing, working conditions and an attractive research environment.

This paper aims to present experimental results related to the performance of cactus mucilage (CM) and brown seaweed extracts (SEs) to inhibit reinforcing steel bar (rebar) corrosion in saturated calcium hydroxide alkaline solutions (pH = 12.5).

Electrochemical cells were prepared using CM solutions at 0.5, 1 and 1.38 per cent concentration (w/v), SE solutions at 0.5, 1, 1.38, 2 and 3 per cent concentration (w/v), sodium alginate at 1 per cent concentration (w/v) and calcium nitrite at 11.3 per cent (v/v). Each cell contained six deformed reinforcing steel bars of 9.5 mm nominal diameter. The experiments were performed at 23 ± 2°C in two stages. The first stage was aimed at stabilizing the rebar until passivation was reached. The second stage included adding NaCl in six steps from 0.5 to 16 g/L. Half-cell potential, linear polarization resistance and electrochemical impedance spectroscopy measurements were monitored during both stages.

The electrochemical test results indicated that both additions reduce the corrosion rate of rebars and pitting in an alkaline media with chloride ions (16 g/L NaCl). Electrochemical impedance spectroscopy results for rebars in natural-added solutions showed higher charge transfer resistance and double layer capacitance values, indicative of the formation of a second interface between the rebar and the electrolyte.

The information obtained was for alkaline solutions only. Further investigation is performed using concrete as the alkaline electrolyte.

CM and SE may be suitable low-cost corrosion inhibitors for steel in concrete.

The use of botanical or algae products for this application will encourage people to consider its production for this particular application. Also, the possible harvest in an environmental friendly way will diminish in the future the use of biohazards and toxic inhibitors.

This investigation is a continuation of a one presented in 2007, which uses only nopal mucilage. This new investigation corroborates what was concluded in the early investigation and incorporates a new natural by product, algae, as a possible corrosion inhibitor product.

The purpose of this paper is to identify the personal characteristics and individual values of Venezuelan low-income entrepreneurs, according to the theoretical framework of the Schwartz model.

A stratified probabilistic sample of 416 individuals was selected from a database of Bangente’s clients, who received microcredits between 1999 and 2016, in the Capital District of Venezuela. The Portrait Value Questionnaire (Schwartz, 2003; Peiró and Palencia, 2009) was applied to measure the values of power, self-direction, stimulation and achievement. The locus of control was measured (Schjoedt and Shaver, 2012) and information was collected on some personal variables. An analysis of hierarchical clusters was conducted to group clients with similar characteristics, as well as a discriminant analysis, to characterize the groups obtained.

The selected Schwartz values, the locus of control and personal characteristics (such as educational level, age and gender) proved to be efficient in discriminating between four groups or profiles of low-income entrepreneurs: those “Focused on progress through effort,” “Independent and ambitious young people,” those “Focused on power and achievement” and those who were “Indifferent.” The results of the cluster analysis were validated using discriminant analysis, which identified the variables with the greatest impact for the characterization of each group. The coefficients of the discriminant functions would allow the classification of a new individual requesting a microcredit into one of the groups obtained. This is a proposal to complement the selection process mechanisms currently used to decide whether or not to grant loans, which must be validated in conclusive studies.

The results cannot be generalized until the study is replicated in representative samples in other entities of the microfinance sector.

The main contribution of this work is the integration of individual values in the profile description of low-income entrepreneurs and in the use of statistical strategies such as cluster analysis and discriminant function. The nature of the study is exploratory: the development of this line of research can guide future decisions about which clients (according to their values, personal characteristics and locus of control) could receive their financial support. When considering these non-traditional variables in the banking context, the aim is to enrich our knowledge about low-income entrepreneurs.

El objetivo de este trabajo es identificar cuáles son las características personales y los valores individuales de los emprendedores populares venezolanos, según el marco teórico del modelo de Schwartz.

Se seleccionó una muestra probabilística estratificada de 416 individuos, de una base de datos de clientes de Bangente beneficiarios de microcréditos entre 1999 y 2016, del Distrito Capital de Venezuela. Se aplicó el Portrait Value Questionnarie (PVQ) (Schwartz, 2003; Peiró y Palencia, 2009) para medir los valores poder, autodirección, estimulación y logro. Se midió el locus de control (Schjoedt y Shaver, 2012) y se recopiló información sobre algunas variables personales. Se llevó a cabo un análisis de conglomerados jerárquicos para agrupar clientes con características similares y un análisis discriminante para caracterizar los grupos obtenidos.

Los valores de Schwartz seleccionados, el locus de control y las características personales (como nivel educativo, edad y género) mostraron ser eficientes para discriminar de forma significativa entre cuatro grupos o perfiles de emprendedores populares: “orientados al progreso por esfuerzo,” “jóvenes independientes y ambiciosos,” “focalizados en el poder y logro” e “indiferentes.” Los resultados del análisis de conglomerados fueron validados por análisis discriminante, que permitió identificar las variables de mayor impacto para la caracterización de cada grupo. Los coeficientes de las funciones discriminantes permitirían clasificar a un nuevo individuo solicitante de microcréditos en alguno de los grupos obtenidos; esta es una propuesta complementaria a los mecanismos de selección actualmente utilizados para decidir la concesión de los créditos, que deberá ser validada en estudios concluyentes.

No se pueden generalizar los resultados hasta que el estudio se replique en muestras representativas en otras entidades del sector microfinanciero.

La mayor contribución de este trabajo está en la integración de los valores individuales en la descripción del perfil de los emprendedores populares y en el uso de estrategias estadísticas como el análisis de conglomerados y la función discriminante. La naturaleza del estudio es exploratoria: el desarrollo de esta línea de investigación puede orientar en el futuro las decisiones acerca de a cuáles clientes (de acuerdo con sus valores, características personales y locus de control) podrían dirigir su apoyo financiero. Al considerar estas variables no tradicionales en el contexto de la banca, se pretende enriquecer el conocimiento sobre los emprendedores populares.
