In this article, the authors explore the emotional dimension of the strategies that researchers carry out to foster collaboration within research groups in science.

The authors have carried out fieldwork based on semi-structured interviews with members of high-performance research groups, supported by the analysis of ethnographic observations in the local work contexts of several of these groups.

As a result, the authors start from the representations of the principal investigators interviewed about collaboration, as a dynamic between the individuals involved and the group, to describe two forms of leadership strategies: ego-centered or group. Hence, the authors highlight that the emotional work of IPs consists of combining both strategies by activating and deactivating affection, warmth and spontaneity in interactions. The authors conclude by reviewing the contributions and some potential lines of study.

The main contributions and conclusions must be regarded considering several limitations of our work. First, the authors have focused on high-performance groups, so it would be expected that the research groups that do not have the support of European Research Council (ERC) do not present the observed dynamics. Concerning the analysis, the authors have focused on the link between situational (personal interaction) and organizational scales. Although the authors have attended social factors that imply the structure and changes of the professional sector of science (Whitley, 2000, 2014), future publications will allow the authors to delve into relationships on a broader scale, associating collaboration patterns and discursive positions. The authors will focus on (1) roles and social profiles and (2) features of scientific culture and its recent configuration.

The authors affirm that the emotional field is key to understanding how groups and individuals respond to these profound changes. In their work, scientific professionals do not only act based on rational and instrumental criteria but also driven by habits, affective networks and inertia of their organizational cultures. In this paper, the authors provide theoretical and practical keys to understand the complexity that collaboration creates within research groups as a contradictory reality that consists of a constant movement of individuals and the group.

As many of the interviewees expressed, there are no adequate spaces to learn and reflect on leadership and collaboration in science. The authors are science workers who are responsible for imagining and deciding how the authors want their research groups to function. Institutions must ensure the means so that this task can be carried out. Hopefully, this article will contribute to this irrevocable project.

The authors’ aim is to understand how well-known groups operate in their field, with a high level of resources and productivity, in order to identify and promote cutting-edge strategies in different scientific branches. Moreover, the authors want to recognize the importance of institutional infrastructures. For this reason, giving them a place in the framework of management studies allows to submit this issue to public debate for a wide audience of social scientists. Moreover, this permits to inquire about cross-disciplinary subjects, such as social and organizational psychology, sociology of work, studies about science and management studies.

Service-learning (SL) is an innovative methodology aiming to improve learning while providing students experiences in the community. Consequently, students also develop social and emotional skills many higher education institutions promise to foster. However, few academic enrichment opportunities are implemented to develop these social skills and university teaching staff are limited in their knowledge of SL to promote active citizenship and civic engagement (Belando-Montoro, Jover, Ruiz de Miguel, Blanco, & Carrasco, 2015). This chapter presents an analysis of the presence of direct and indirect indicators related to social responsibility and SL in the degree programs of the Social and Legal Sciences area of the Complutense University of Madrid. These indicators include questions related to the social environment needs diagnosis and the design of projects that meet these needs, the environmental care, among others. The results indicate the lack of presence of courses on the direct indicators in the degrees offered. However, the focus on indirect indicators is relatively common. In particular, those common indirect indicators are related to critical thinking about social reality, the environment needs diagnosis, and the development of social intervention. The findings suggest universities increase their focus on social responsibility and community service in the university curriculum, providing training oriented toward socio-community intervention.

This paper presents a comparative analysis of artwork produced in the context of social movements waged by Mexicans and Chicanos (U.S. inhabitants of Mexican descent) during the two decades between the mid-1960s and the mid-1980s. Despite the fact that activists in these movements shared many elements of Mexican culture and history, were part of the same generation of radical social movements born in the 1960s, and experienced some significant interchange among movement participants from each side of the U.S.-Mexico border, an examination of movement art reveals significant differences in key elements of the movements’ collective identity and expression of political citizenship. Analysis of the artwork also highlights different aesthetic choices made by movement artists, particularly with regard to the deployment of formal elements associated with the “Mexican School” of art made famous by artists associated with the Mexican Revolution of the early 20th century. Variations in the representational strategies developed by movement artists reflect the distinct relationship of movement constituents in Mexico and the U.S. to each nation's prevailing regimes of accumulation and modes of regulation. The analysis is based on an examination of 374 pieces of art.

This study aims to assess the relationship between cash management and fund performance in index fund portfolios.

Using a sample of 104 index mutual funds that track the Standard and Poor 500 stock market index from January 1999 to December 2016, the authors employ quintile portfolios and different regression models to assess the differences in risk-adjusted monthly returns experienced by index funds managing different cash levels in their portfolios. To ensure the robustness of the results, different sub-periods and market states are considered in the analyses as well as other exogenous factors and fund characteristics affecting the level of portfolio cash holdings and index fund performance.

Results show that index funds holding higher levels of cash and cash equivalents performed significantly worse than their low-cash counterparts. This evidence remains even after considering different sub-periods and bullish and bearish market conditions and controlling for fund expenses and other variables that could drive this cash-performance relationship.

This study expands the extant literature analyzing cash management in the mutual fund industry. More specifically, the analyses focus on index fund portfolios that replicate a specific benchmark, given that their performance differences should not be related to the market evolution but to the factors derived from the fund management and other exogenous issues. These findings are of interest to managers and investors willing to improve their risk-adjusted returns while investing as diversified as a stock market index.

El objetivo de este estudio es analizar la relación existente entre la gestión de efectivo y el desempeño consiguiente en las carteras de fondos de inversión indexados.

Utilizando una muestra de 104 fondos que replican el índice bursátil Standard and Poor's 500 desde enero de 1999 hasta diciembre de 2016, se emplean carteras hipotéticas que invierten en fondos similares y diferentes análisis de regresión para analizar las diferencias en las rentabilidades ajustadas mensuales entre fondos indexados que gestionan diferentes niveles de efectivo en sus carteras. Por motivos de robustez, se tienen en cuenta diversos subperiodos y estados de mercado, así como otros factores exógenos y características de los fondos que afectan tanto al nivel de efectivo mantenido en la cartera indexada como al desempeño de la misma.

Los resultados muestran que los fondos indexados que gestionan niveles de efectivo más elevados experimentan un desempeño significativamente menor que otros fondos comparables que mantienen menores porcentajes de efectivo en sus carteras de inversión. Se obtiene una evidencia similar tras considerar diferentes subperiodos y momentos alcistas y bajistas de mercado, así como al considerar los gastos propios de cada fondo y otras variables que podrían afectar esta relación entre el rendimiento y el efectivo gestionado.

Este estudio contribuye a la literatura existente que analiza la gestión de efectivo en la industria de fondos de inversión. Más específicamente, los análisis se centran en carteras de fondos que replican un índice bursátil específico, dado que las diferencias en sus rendimientos en este tipo de fondos no deberían originarse por la evolución del mercado, sino a causa de factores relacionados con la gestión de sus carteras y otros componentes exógenos al índice bursátil. Estos hallazgos son de interés para gestores e inversores que pretendan mejorar sus rentabilidades ajustadas al invertir mediante una estrategia tan diversificada como un índice bursátil.

The purpose of this paper is to translate consumer requirements regarding olive-oil quality attributes into specific olive-growing practices that most contribute to satisfy these attributes.

After identifying consumer requirements or needs regarding different attributes of olive-oil quality, through a survey of 439 olive-oil consumers, the authors determine the olive-growing practices that optimally satisfy consumer needs through expert opinions. Finally, the use of expert knowledge to construct the House of Quality or the first matrix of quality function deployment allow the authors to define the relative contribution of the various olive-farming practices to the satisfaction of consumer requirements.

The findings have shown that the olive-oil quality attributes most requested by consumers incorporate organoleptic (e.g. acidity, flavour, colour), sociocultural (e.g. creating employment in rural areas, maintenance of the rural population) and environmental ones (environmental externalities). The “separation of olives collected from ground and trees” (separation), “timing of harvesting” (according to a fruit-ripeness index), the “method of the ground harvest” (no picking from the ground), and the “method of tree harvest” (handpicking) were some of the most commonly identified olive-farming practices that contribute the most to meeting consumers’ needs with regard to olive-oil quality.

The study suggests detailed analyses of the relationships between customer requirements and other agents practices involved in the olive sector (processing industries: mills, distribution, and marketing management, etc.) to more fully investigate the impact of all these practices on consumers’ perceived olive-oil quality attributes. This is the most reliable way to guarantee that the most sought-after quality characteristics are taken into account, not only in the farming stage but also in the various different stages of the olive agri-food chain.

Findings represent an opportunity in the market value chain to develop a quality olive oil which is more oriented towards the consumer and able to face future segmentations in the market. This is one of the main innovative features of this study, as it offers “good practice” guidelines to agents of the olive-oil sector from the consumer perspective.

This study provides positive implications to consumers, providing them important tools to make an informed choice, and producers and marketers helping the design of production strategies to optimally satisfy the consumer preference with regard to olive-oil quality, and attain a competitive advantage by adding value to the product.

This paper is regarded as the pioneer in the literature translating the “consumer voice” regarding olive-oil quality into specific olive-growing practices “good-practices guidelines”. Thus, the relevant required quality olive-oil attributes should be clearly described on the label, to enable consumers to identify the quality features and make an informed choice. Furthermore, to meet consumers’ needs, the olive-oil sector should focus on the olive-growing practices that optimally satisfy consumer requirements concerning olive-oil quality attributes. This would help to improve legitimacy and boost public support for the Common Agricultural Policy subsidies for the agricultural sector in general, and the olive sector in particular. The findings are particularly valuable in helping policy makers to design marketing strategies to improve the sustainability and competitiveness of Spanish olive oil.

This paper aims to develop a novel strategy to manufacture poly-lactic acid (PLA) filaments reinforced with Mg particles for fused filament fabrication of porous scaffolds for biomedical applications.

The mixture of PLA pellets and Mg particles was extruded twice, the second time using a precision extruder that produces a filament with zero porosity, constant diameter and homogeneous dispersion of Mg particles. The physico-chemical properties of the extruded filaments were carefully analysed to determine the influence of Mg particles on the depolymerisation of PLA during high temperature extrusion and the optimum melt flow index to ensure printability.

It was found that the addition of a polyethylene glycol (PEG) plasticizer was necessary to allow printing when the weight fraction of Mg was above 4%. It was possible to print porous face-centre cubic scaffolds with good geometrical accuracy and minimum porosity with composite filaments containing PEG.

The new strategy is easily scalable and seems to be very promising to manufacture biodegradable thermoplastic/metal composite filaments for 3D printing that can take advantage of the different properties of both components from the viewpoint of tissue engineering.

The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

The purpose of this paper is to determine the relation between quality of life (QoL), mental illness, challenging behaviour and institutionalisation in an adult population with intellectual disabilities (ID).

The study assessed the QoL and its conditioning factors in 142 subjects with different degrees of ID. The GENCAT and Quality of Life in Late Stage Dementia scale were used to evaluate QoL, the Psychiatric Assessment Schedule for Adults with Developmental Disability and Diagnostic Assessment for the Severely Handicapped-II scale to assess mental illness and the Inventory for Client and aetiology Planning scale to assess challenging behaviour.

Individuals who live in residential care homes were found to have significantly impaired QoL (<0.001). Individuals with challenging behaviour presented significantly lower QoL, regardless of ID aethiology and degree, while psychiatric disorders did not seem to have a direct influence on individual QoL.

This paper provides new insight into the importance of challenging behaviour and psychiatric disorders in the QoL of individuals with ID.

The purpose of this paper is to establish the importance of accounting in the management of Spanish military hospitals by the St John’s Order (SJO) of the Roman Catholic Church in the eighteenth century, a time of crisis between the Church and the State. The sacred mission of the Order required that they had a significant role outside the Roman Catholic Church in the care and treatment of the sick and infirm which required them to establish hospitals throughout Spain and across the lands that it had conquered. The study establishes that accounting played a key role in ensuring the success of the unconventional commercial relationship between the SJO and the government and the military.

Niebuhr’s typology is used to help understand how accounting practices were consistent, indeed essential, expectations of the sacred mission of the SJO and not something which represented a denial of the Order’s religious beliefs. The paper relies primarily on documents and other material located in Spanish archives.

The SJO accepted that secular accounting and accountability processes were relevant to their search for God’s love and to showing this love to others. The need for the Order to be accountable to the State was not regarded as profane and antithetical to their religious beliefs. Adopting Niebuhr’s typology of religion and society, this study concludes that the Order was an extraordinary example of Christ the transformer of the culture.

This study recognises the need to deepen the understanding of the way in which accounting practices have often played a critical role in the activities of religious organisations by examining an extraordinary example of one organisation which was engaged in an unusual, ongoing, highly complex commercial relationship with the Spanish State.

It is well known in the mining industry that the increase in failures and breakdowns is due mainly to a poor maintenance policy for the equipment, in addition to the difficult access that specialized personnel have to combat the breakdown, which translates into more machine downtime. For this reason, this study aims to propose a remote assistance model for diagnosing and repairing critical breakdowns in mining industry trucks using augmented reality techniques and data analytics with a quality approach that considerably reduces response times, thus optimizing human resources.

In this work, the six-phase CRIPS-DM methodology is used. Initially, the problem of fault diagnosis in trucks used in the extraction of material in the mining industry is addressed. The authors then propose a model under study that seeks a real-time connection between a service technician attending the truck at the mine site and a specialist located at a remote location, considering the data transmission requirements and the machine's characterization.

It is considered that the theoretical results obtained in the development of this study are satisfactory from the business point of view since, in the first instance, it fulfills specific objectives related to the telecare process. On the other hand, from the data mining point of view, the results manage to comply with the theoretical aspects of the establishment of failure prediction models through the application of the CRISP-DM methodology. All of the above opens the possibility of developing prediction models through machine learning and establishing the best model for the objective of failure prediction.

The original contribution of this work is the proposal of the design of a remote assistance model for diagnosing and repairing critical failures in the mining industry, considering augmented reality and data analytics. Furthermore, the integration of remote assistance, the characterization of the CAEX, their maintenance information and the failure prediction models allow the establishment of a quality-based model since the database with which the learning machine will work is constantly updated.
