The purpose of this paper is to assess the quality of commercial lubricant oils. A spectroscopic method was used in combination with multivariate regression techniques (ordinary multivariate multiple regression, principal components analysis, partial least squares, and support vector regression (SVR)).

The rationale behind the use of SVR was the fuzzy characteristics of the signal and its inherent ability to find nonlinear, global solutions in highly complex dimensional input spaces. Thus, SVR allows extracting useful information from calibration samples that makes it possible to characterize physical-chemical properties of the lubricant oils.

A dataset of 42 spectra measured from oil standards was studied to assess the concentration of copper into the oils and, thus, evaluate the wearing of the machinery. It was found that the use of SVR was very advantageous to get a regression model.

The use of genetic algorithms coupled to SVR was considered in order to reduce the time needed to find the optimal parameters required to get a suitable prediction model.

The purpose of this study was to explore the innovative and proactive practices adopted by subsistence businesses under the COVID-19 health contingency. Evidence of the current situation and the contingency practices that businesses have implemented in dealing with the economic crisis caused by the COVID-19 pandemic was collected through a literature review of secondary information sources: bibliographic and hemerographic, as well as in-depth interviews with five owners of artisanal and agricultural subsistence businesses.

Faced with uncertainty, artisanal and agricultural subsistence businesses have adopted innovative and proactive survival practices. The closure of markets, the absence of tourism, the suspension of non-essential activities, the lack of mobility and transportation, and the closure of access in rural communities are some of the realities these businesses are experiencing. Subsistence businesses in marginalised areas are a long way from accessing information technologies for online sales and home deliveries, which are implemented by most businesses in urban areas. In contrast, they revert to ancestral marketing practices such as bartering and low prices to earn an income for family food. Despite the loss of over 50% of subsistence businesses in urban and semi-urban areas, online sales through social media and websites, socially responsible initiatives, along with government support programmes, have helped others stay in business.

The purpose of this study has the aim of expanding lessons learned that were originally detected for information literacy (INFOLIT) programs in Ibero-American universities (from Latin America, Spain and Portugal), this paper presents lessons learned for enhancing equivalent programs offered by other universities around the world.

As this paper is a comparative literature review, the methodology involved three stages. Initially, a documentary analysis was carried out to identify the texts published during the past five years – since 2013 – reporting a categorization of experiences and cases of international INFOLIT programs and their corresponding lessons learned. Second, we conducted a content analysis of these publications to uncover the classification, identification and frequency of the lessons learned. A third comparative step consisted of analyzing the similarities of these lessons when compared to those reported in similar research on Ibero-American universities (Uribe-Tirado, 2013).

From the 75 lessons learned from INFOLIT programs in Ibero-American universities, 65 lessons (87 per cent) were identified as also present in universities elsewhere. These similarities give an account of the possibilities for collaborative learning and benchmarking that INFOLIT programs could achieve with regard to content, pedagogy, learning objects and evaluation if there were more networking and more common participation in sharing experiences, with appropriate adaptations to contextual, technological and idiomatic variations.

As a comparative literature review, this paper makes a significant contribution to the international advancement of INFOLIT in higher education, as it correlates the lessons learned from INFOLIT programs in Ibero-American universities with those from other countries. This provides a global view of the lessons learned about INFOLIT, which to date have not been reported with such a wide scope and number of lessons.

Most studies on work–life support at workplaces consider work–life balance to be a women’s issue, either explicitly or implicitly. This chapter analyses how fathers who are involved caregivers are supported or hindered in attaining work–life balance by their workplaces. It explores the following three questions: (1) why fathers value some job adaptations over others compared with mothers; (2) how organizational cultures influence the work–life balance of new fathers and (3) what differences exist across public and private sectors as well as large versus small companies. A qualitative approach with three discussion groups and 22 involved fathers enables us to explore these issues for large companies, public sector workplaces and small businesses. We find that tight time schedules, flextime, telework, schedule control and fully paid nontransferable leaves of absence constitute policies that favor involved fatherhood, while measures without wage replacement generate fear of penalization in the workplace and do not fit the persistent relevance of the provider role. In addition, un-similar supervisors, envy, lack of understanding and gender stereotypes among co-workers and clients constitute cultural barriers at the workplace level. Contrary to our expectations, small businesses may offer a better work–life balance than large companies, while the public sector is not always as family-friendly as assumed.

The study aims to provide relevant information on the educational processes experienced by university students in Spain during the period of compulsory confinement. To this end, the key factors of the emergency educational model implemented by the country's universities have been analysed.

The study investigated, through qualitative, exploratory research and 30 in-depth interviews, how university students have lived the process of change to alternative forms of education during the crisis, what training experiences stand out and what factors related to virtual education they identify as relevant keys.

Participants usually focus on three main topics: (1) The impacts of changes in training development with regard to methodologies and forms of assessment; (2) The facilities and difficulties in this new modality of online training; and (3) The consequences of the crisis on higher education in the medium and long term.

Students participating in the study offer relevant and critical information on the adaptations developed by Spanish universities during the Coronavirus crisis. This information can be fundamental for the conscious decision making of the institutions, so that they can develop educational processes more adequate to the needs and possibilities of the university students in times of crisis.

The purpose of this paper is to present a new vision-based control method, which enables delta-type parallel robots to track and manipulate objects moving in arbitrary trajectories. This constitutes an enhanced variant of the linear camera model-camera space manipulation (LCM-CSM).

After obtaining the LCM-CSM view parameters, a moving target’s position and its velocity are estimated in camera space using Kalman filter. The robot is then commanded to reach the target. The proposed control strategy has been experimentally validated using a PARALLIX LKF-2040, an academic delta-type parallel platform and seven different target trajectories for which the positioning errors were recorded.

For objects that moved manually along a sawtooth, zigzag or increasing spiral trajectory with changing velocities, a maximum positioning error of 4.31 mm was found, whereas objects that moved on a conveyor belt at constant velocity ranging from 7 to 12 cm/s, average errors between 2.2-2.75 mm were obtained. For static objects, an average error of 1.48 mm was found. Without vision-based control, the experimental platform used has a static positioning accuracy of 3.17 mm.

The LCM-CSM method has a low computational cost and does not require calibration or computation of Jacobians. The new variant of LCM-CSM takes advantage of aforementioned characteristics and applies them to vision-based control of parallel robots interacting with moving objects.

A new variant of the LCM-CSM method, traditionally used only for static positioning of a robot’s end-effector, was applied to parallel robots enabling the manipulation of objects moving along unknown trajectories.

This paper aims to examine the role of organizational innovative capabilities (OIC) on the relationship between knowledge sharing (KS), corporate entrepreneurship (CE) and firm performance (FP). Specifically, this study uses the knowledge-based view to develop a model that examines the mentioned relationship.

Using survey data from 520 participants across 75 service sector companies in Thailand, measurement and structure models are tested through structural equation modeling to quantify the impact between constructs.

This study shows that KS and CE positively affect OIC and FP. A positive relationship is also found between KS and CE. The mediating impact of OIC strengthens the relationship between KS and CE on FP.

Like all research using survey methods, the research is prone to respondent biases and generalizability. However, this paper has put the best effort to minimize such effects by rigorous methodological testing to avoid such biases.

The findings of this study suggest that to improve organizational learning and knowledge-based performance, commitment and understanding of the employees in the entire organization is crucial. KS significantly contributes to developing innovative abilities because of its characteristics of providing firm-specific and socially complex advantages. The way a firm transforms and exploits its knowledge may ascertain its level of innovativeness, such as coming up with certain problem-solving procedures and new product development according to the rapid change in the market demand. However, organizations may only instigate to effectively organize knowledge when their employees are ready to share knowledge. Continuous KS boosts entrepreneurial practices and contributes innovativeness across individuals, groups, units or the entire organization.

The relationship between CE, organization innovative capabilities and FP in the presence of KS is rarely discussed in both theoretical and empirical literature. This study contributes to the literature by arguing that apart from the direct impact of KS on FP, KS can lead the firms toward generating important competitive advantage by forming innovative capabilities that can significantly influence FP.
