Abstract
Purpose
This paper aims to present a procedure to change the orientation of a grasped object using dexterous manipulation. The manipulation is controlled by teleoperation in a very simple way, with the commands introduced by an operator using a keyboard.
Design/methodology/approach
The paper shows a teleoperation scheme, hand kinematics and a manipulation strategy to manipulate different objects using the Schunk Dexterous Hand (SDH2). A state machine is used to model the teleoperation actions and the system states. A virtual link is used to include the contact point on the hand kinematics of the SDH2.
Findings
Experiments were conducted to evaluate the proposed approach with different objects, varying the initial grasp configuration and the sequence of actions commanded by the operator.
Originality/value
The proposed approach uses a shared telemanipulation schema to perform dexterous manipulation; in this schema, the operator sends high-level commands and a local system uses this information, jointly with tactile measurements and the current status of the system, to generate proper setpoints for the low-level control of the fingers, which may be a commercial close one. The main contribution of this work is the mentioned local system, simple enough for practical applications and robust enough to avoid object falls.

Abstract
Purpose
The purpose of this paper is to focus on the underpinning dynamics that explain collective intelligence.
Design/methodology/approach
Collective intelligence can be understood as the capacity of a collective system to evolve toward higher order complexity through networks of individual capacities. The authors observed two collective systems as examples of the dynamic processes of complex networks – the wiki course PeSO at the Universidad de Los Andes, Bogotá, Colombia, and an agent-based model inspired by wiki systems.
Findings
The results of the wiki course PeSO and the model are contrasted with a random network baseline model. Both the wiki course and the model show dynamics of accumulation, in which statistical properties of non-equilibrium networks appear.
Research limitations/implications
The work is based on network science. The authors analyzed data from two kinds of networks: the wiki course PeSO and an agent-based model. Limitations due to the number of computations and complexity appeared when there was a high order of magnitude of agents.
Practical implications
Better understanding can allow for the measurement and design of systems based on collective intelligence.
Originality/value
The results show how collective intelligence emerges from cumulative dynamics.

Abstract
This study, carried out in the bilingual and bicultural border area of South Texas, is an exploration of bilingual preservice teachers’ identity formation and their experiences and beliefs about literacy and biliteracy during an undergraduate class focused on learning about emergent literacy in the bilingual classroom. This study is based on a sociocultural approach to learning and identity development, and research that explores how bilingual teachers’ identity is shaped through their participation in cultural and linguistic practices. The purpose of this practitioner research is to provide insights into preservice teachers’ identities as they start to explore literacy and biliteracy practices. Two research questions guide the study: What experiences about literacy and biliteracy development do prospective teachers identify as meaningful? How do these experiences contribute to define bilingual preservice teachers’ identities? Findings indicate that bilingual preservice teachers’ identities are shaped by cultural and linguistic experiences that define the bilingual and bicultural dynamics of the region. Two predominant types of experiences impact bilingual preservice teachers’ beliefs about teaching, learning, and literacy/biliteracy development. Particularly significant in defining their perceptions are the lessons learned from meaningful others – especially mothers and teachers – and certain relevant memories regarding effective practices they experienced when learning to read and write. Implications for teacher education preparation of bilingual teachers are identified.

Abstract
This chapter analyzes the development of the relationship between the social sciences and sport in Argentina – from its first steps, to the present, and to possible future issues. The description of Arbena (1999) from the last part of twentieth century about the situation of the social sciences and sport in Latin America in general and Argentina in particular could not be more precise:
Latin America has produced little scholarly analysis of sport and society, though information and insights are found in other types of writings, journalistic accounts such as club histories and popular biographies. What has been focused on soccer normally treats only the author’s own country, and is rarely available in English. Nowhere does a single author or academic group dominate. (Arbena, 2000, p. 548)

We also make reference to how the anthropologist Eduardo Archetti breaks that mold described by Arbena and how he becomes the undisputed referent in the study of the social sciences and sport in Argentina, and how his immense contribution is recognized in the region. We analyze the present status of this topic, its major changes, the development that the area has undergone so far, and the issues that are being studied today. Moreover, we mention the importance of sociology of sport in the academic field and its formalization. Finally, this chapter also considers possible future trends in the sociology of sport in Argentina.

Abstract
Purpose
The purpose of this paper is to investigate the impact of increasing trade and investment relations between China and Latin American economies. The paper focuses on the threats and opportunities that permeate this relationship.
Design/methodology/approach
The paper surveys existing literature and secondary data in Spanish, Portuguese, and in English to investigate the different ramifications of this dynamic relationship between China and Latin American economies.
Findings
After analyzing trade and investment trends and data, it is clear that Latin American economies must make changes to increase their participation in the Chinese market. Direct involvement with China is inherently risky, however, the opportunities obviously make the alliance necessary. Latin American economies are under increasing pressure to revamp their business environments and to implement long‐term strategies in order to compete more efficiently with China, domestically and in third‐markets. China has showed Latin American economies that investments in education, R&D, innovation, infrastructure, and friendly business policies, both facilitate and foster the creation of new competitive advantages.
Originality/value
This paper highlights and contributes to a better understanding of the ongoing challenges and opportunities permeating the Chinese Latin America's trade and investment relationship, as well as a indicating a number of areas for further study.

Abstract
Why are some of the municipalities located on the most dynamic, populous and productive region of a nation, also the poorest of the nation? Why after decades of being at the center of national development policies, the municipalities of Greater Buenos Aires are still suffering some of the worst development indicators of the Argentina?

Abstract
Purpose
The purpose of this paper is to analyze the relationship between financial and operational performance and the application of two different talent management (TM) models: internal talent development model and external talent capture model. Comparative case studies of the Football Club Barcelona and the Real Madrid Football Club allow drawing a definitive conclusion for TM in companies related to the competitive strategy.
Design/methodology/approach
The two TM models are examined via a longitudinal comparative case study analysis: FC Barcelona and Real Madrid CF. Present paper builds on secondary sources: first, the TM properties of the clubs were extracted from academic sources and newspapers; second, data used to analyze the financial performance were derived from SABI database and operational performance was measured as the effectiveness in winning trophies in football championships (data gathered from Union of European Football Associations and International Federation of Football Associations databases).
Findings
The case analysis reveals that the two TM models offer equally effective financial and operational performance outcomes. The internal talent development model would be more useful for companies whose competitive advantage is achieved through differentiation through teamwork. However, companies that do not achieve a clear differentiation through teamwork should opt for the external talent capture model.
Originality/value
Talent is one of a company’s most important intangible assets. Although there exists a growing interest among companies as to the best way to TM, practical models on how to manage talent are virtually nonexistent. Comparative case studies from the sports arena allow for the extraction of lessons for companies related to TM and competitive strategy.

Abstract
This chapter aims to contribute to the study of social protests around the world and particularly in Latin America during the 1960s and 1970s, with a focus on an Argentinean case. Throughout these years, Argentina like many other Latin American societies witnessed the growth and development of intense social and political struggles in concert with the armed insurgency. Did workers or other popular social sectors support guerrilla organizations in Argentina? What was the interconnection between working-class and armed insurgent struggle? This chapter examines these liaisons by studying the case of an industrial city that has been identified to be a paradigm of labor radicalization and political violence in Argentina—Villa Constitución. Through the reanalysis of documents and sources as well as interviews, we discuss established interpretations on armed and labor struggles that reveal a broader heterogeneity in the forms of social support to revolutionary violence. Solidarity among workers and armed militants appears in (1) the actions of militant workers at their workplaces, and (2) the armed actions organized by militants in support of worker’s fights.” These two groups reinforced each other's activism. But, by no means can we directly deduct from this that rank and file workers immediately identified their strikes with ideologically revolutionary objectives.
