Abstract

Purpose

The purpose of this paper is to explore the variety of food in which it has been applied as a prebiotic and functional ingredient, the concentrations used there in, the tests that have been conducted on these fortified foods and briefly reviews the history and characteristics of inulin.

Design/methodology/approach

The review included articles from 1999-2013. The papers which reported inulin concentrations used, the purpose of the application and tests on final product, were mainly selected. Articles were collected in electronic databases such as Elsevier-Science Direct, Emerald, Springer Link, Wiley and Redalyc.

Findings

The interaction inulin-food with different food matrices is complex, and is not always technologically favorable for the product. Moreover, additional to evaluations of sensory, physicochemical and rheological characteristics, it is essential to carry out measurements in the food, of such characteristics as prebiotic content, and prebiotic activity in vivo and in vitro, and assess potential adverse reactions in order to define suitable doses of consumption.

Originality/value

The paper highlights the importance of conducting in vitro and in vivo testing of potential prebiotic inulin-supplemented food in order to define dose that benefit health and do not cause unacceptable gastrointestinal distress.

Abstract

Learning outcomes

The contribution of the present case lies in the critical view that every business actor should exercise – be it general manager, middle management, supervisor or executive – when building a strong organizational culture in corrupt political environments.

Case overview/synopsis

The purpose of this case study is to explore the dilemma in which Marcelo Odebrecht, once CEO of Odebrecht, found/determined whether to continue with the business model established by the founders of Odebrecht or take a new path for the organization. After exploring the corrupt acts of Odebrecht and the scope of Operation Lava Jato, the reader can reflect on the importance of organizational culture (according to the three levels proposed by Schein) in the face of the emergence of corruption. By generating discussions about organizational culture, business ethics, political culture and corruption, the organizational culture of Odebrecht is problematized in relation to its real behavior.

Complexity academic level

Students of administration, business and international business undergraduates and graduates, as well as members of senior management in companies in the infrastructure sector. Also, given the plurality of possible readings, it is recommended that the case also be used in courses or specializations in organizational psychology, organizational sociology or organizational anthropology.

Abstract

Purpose

The purpose of this paper is to introduce a multi‐agent architecture, which offers services to be applied in B2C e‐Marketplaces and to present the core system: the search agent.

Design/methodology/approach

The different parts that compose an e‐commerce portal are naturally performed through intelligent agents, which have the ability to communicate with one another and autonomously act depending on defined goals.

Findings

The search agent returns the more relevant results in direct shopping than others previously used. It is based on a usability‐improved fuzzy searching mechanism that allows the specification of uncertain and vague searching preferences.

Research limitations/implications

More empirical research efforts need to be directed to study the efficiency over time. This work is based on a prototype, which is its main limitation.

Practical implications

Intelligent agents can be useful to improve e‐commerce services in B2C portals.

Originality/value

The research extends previous authors' work on the application of intelligent agents to e‐commerce fields.

Abstract

Purpose

Opportunity-driven entrepreneurship (ODEs) is a key to economic development. Consequently, the emigration of potential ODEs constitutes a barrier to the development of the country of origin. Thus, this study examines how the combined effect of subjective insecurity, corruption perception, subjective norm towards emigration, socioeconomic level and the entrepreneurial intention of potentially opportunity-driven university students can affect their propensity to emigrate.

Design/methodology/approach

A sample of students (N = 354) from the Technological University of the State of Zacatecas is surveyed, and a causal model based on the fuzzy set qualitative comparative analysis (fsQCA) configuration methodology is proposed.

Findings

The results suggest that future graduates are more likely to emigrate when their corruption and/or insecurity perceptions are high. In addition, the subjective norm is decisive when taking the decision to emigrate. Finally, in the specific cases of individuals with the highest entrepreneurial intentions as well, their perceptions of corruption and insecurity have a great influence.

Originality/value

This study addresses, from a cognitive point of view, the effect on ODEs of phenomena that are strongly prevalent in Mexico, such as citizen insecurity, corruption, poverty and the migratory tradition.

Propósito

El emprendimiento por oportunidad es clave en el desarrollo económico de los territorios. De esta forma, la emigración de individuos potencialmente emprendedores por oportunidad constituye un freno al desarrollo del país de origen. Así, en esta investigación se estudia cómo el efecto combinado de la inseguridad subjetiva, la percepción de corrupción, la norma subjetiva hacia la emigración, el nivel socioeconómico y la intención emprendedora que presentan los estudiantes universitarios potencialmente emprendedores por oportunidad puede afectar a su propensión a emigrar.

Diseño/metodología/enfoque

Se emplea una muestra de alumnos (N = 354) de la Universidad Tecnológica del Estado de Zacatecas (UTZAC) y se plantea un modelo causal siguiendo la metodología configuracional fsQCA.

Hallazgos

Los resultados sugieren que los futuros egresados presentan mayor propensión a emigrar cuando su percepción de corrupción y/o inseguridad son altas. De la misma manera, la norma subjetiva es determinante a la hora de tomar la decisión de emigrar. Finalmente, en el caso concreto de los individuos con mayor intención emprendedora también se aprecia una gran influencia de su percepción de corrupción y de inseguridad.

Originalidad/valor

Este estudio aborda desde un punto de vista cognitivo el efecto sobre el emprendimiento por oportunidad de fenómenos muy presentes en México como son la inseguridad ciudadana, la corrupción, la tradición migratoria y la pobreza.

Abstract

Purpose

The purpose of this paper is to explore the hypothesis that collaboration was a key characteristic of Cuban science to maintain their scientific capacity during a period of economic restrictions and an important feature of Cuban science policy and practice for the benefit of society.

Design/methodology/approach

Collaboration was studied through Cuban scientific publications listed in PubMed for the period 1990-2010. The search was carried out using the advanced search engine of PubMed indicating < Cuba > in the affiliation field. To identify participating institutions a second search was performed to find the affiliations of all authors per article through the link to the electronic journal. A data set was created to identify institutional publication patterns for the surveyed period. Institutions were classified in three categories according to their scientific production as Central, Middle or Distal: the pattern of collaboration between these categories was analysed.

Findings

Results indicate that collaboration between scientifically advanced institutions (Central) and a wide range of national institutions is a consequence of the social character of science in Cuba in which cooperation prevails. Although this finding comes from a limited field of biomedical science it is likely to reflect Cuban science policy in general.

Originality/value

Using bibliometric tools the study suggests that Cuban science policy and practice ensure the application of science for social needs by harnessing human resources through national and international collaboration, building in this way stronger scientific capacity.
