Abstract
Purpose
The aging of the population, high prevalence of chronic diseases, and increased need for evidence‐based practice are factors that have boosted a high demand for clinical trials in the United States. In recent years, an increasing number of clinical trials have shifted from academic medical centers, to community‐based practices, to global sites in different countries. Contract research organizations (CROs) are service organizations that provide research and support services to pharmaceutical, biotechnological, and health companies. This paper aims to explore the evolution of the CRO industry in the United States and worldwide, and to discuss the benefits and pitfalls of the globalization of CROs.
Design/methodology/approach
The organizational ecology framework is used to analyze the lifecycle of CROs in response to their environment including their emergence, growth, and evolution to date.
Findings
The authors discuss the drug development process, the role of CROs and outsourcing in clinical research. Pharmaceutical companies began outsourcing research activities to increase their profit margins and better position themselves in the rapidly‐changing healthcare environment. The paper analyzes the evolution of the CROs over time and the factor that affected it, including the current globalization stage with special emphasis in India, China and Central and Eastern Europe. Consequences of globalization include the stimulation of research collaboration, policy and issues related to quality.
Originality/value
The evolution of CROs over time points to transformation/evolution of these organizations, with challenges as they become an integral part of the drug development process in the USA and other countries.

Abstract
Purpose
The mechanical performances of 3D-printed parts are influenced by the manufacturing variables. Many studies experimentally evaluate the impact of the process parameters on specimens’ static and dynamic behavior with the aim of tailoring the mechanical response of the prints. However, this experimental approach is hampered by the very large number of parameters, 3D printers and materials, the development of computer simulation models being thus required. In the context, this study aims to fill a gap by experimentally investigating the influence of infill related parameters over the vibrations of 3D-printed specimens, as well as to propose and validate a parametric finite element (FE) model for the prediction of eigenfrequencies.
Design/methodology/approach
A generally applicable FE model is not yet available for the 3D printing technology based on the material extrusion process due to the large number of parameters settings that determine a large variability of outcomes. Hence, the idea of developing numerical simulation models that address sets of parameters and assess their impact on a certain mechanical property. For the natural frequency, the influence of the infill density and infill line width is studied in this paper. An FE script that automates the generation of the model geometry by using the considered set of parameters is developed and run. The results of the modal analysis are compared to the experimental values for validating the script.
Findings
Based on the experimental results, a linear regression between the weight of the part and the first natural frequency is established. The response surfaces indicate that the infill density is the most significant parameter of influence. The weight-frequency function is then used for the prediction of the natural frequency of specimens manufactured with other infill parameters and values, including different infill patterns.
Practical implications
As the malfunctions or mechanical damages can be caused by the resonant vibration of parts during use, this research develops a FE-parameterized model that evaluates and predicts the eigenfrequencies of 2D printed parts to prevent these undesirable events. The targeted functional applications are those in which 3D-printed polymer parts are used, such as drone arms or drone propellers.
Originality/value
This research studies the influence of process parameters on the natural frequency of 3D-printed polylactic acid specimens, a topic scarcely addressed in literature. It also proposes a new approach for the development of parameterized FE models for sets of parameters, instead of a general model, to reduce the time and resources allocated to the experimental tests. Such a model is provided in this paper for evaluating the influence of infill parameters on 3D prints eigenfrequency. The numerical model is validated for other infill settings.

Abstract
Purpose
This study explores the enablers of students “entrepreneurial intentions by identifying the factors that raise students” interest in embracing an entrepreneurial career.
Design/methodology/approach
Entrepreneurship education is increasingly attracting attention as a means of fostering entrepreneurial activity and creating a culture of innovation. Developing students' entrepreneurial intentions is critical to promote entrepreneurship. This research is built on a mixed method approach of partial least squares structural equation modelling and fuzzy-set qualitative comparative analysis.
Findings
The factors that influence students ‘entrepreneurial intentions are identified: business incubation programmes, non-reimbursable grants for entrepreneurial students, networking events to promote entrepreneurship, mentoring services, innovation labs for business idea validation and entrepreneurship courses. This knowledge can help develop effective entrepreneurship education programmes. The study also provides actionable insights for educational institutions and policymakers. It underscores the need for innovative educational platforms such as entrepreneurial bootcamps. It also highlights the value of advanced learning environments such as decision theatres to foster a culture of entrepreneurship and innovation.
Originality/value
The study contributes to the body of knowledge on entrepreneurship education. It highlights the need for a multidisciplinary approach to understand the factors that shape students’ entrepreneurial intentions.

Abstract
During the last three decades or so, the introduction of gender studies into higher education in Romania as a field of teaching and research has proved to be a very uneven and sometimes precarious process. The notion of gender has not been properly integrated into scholarly research, and women’s and gender studies have therefore been seen as an appendix to mainstream research in the humanities and the social sciences. This chapter aims at providing a meaningful picture of how gender studies have become part of the higher education system in Romania, what challenges have been met on the way and what future gender studies have in the education landscape. It also provides a comprehensive overview of the significance and importance of the TARGET project for the implementation of the first gender equality plan in the Romanian higher education system.

Abstract
Purpose
The present paper explores Generation Z university students' clusters based on the consumption of daily fruits and vegetables in an emerging market economy, indicating young people's reasons to adopt a healthy diet.
Design/methodology/approach
Using cluster theory, the authors analyse Generation Z university students who consume fresh fruits and vegetables, highlighting aspects of a healthy diet, in compliance with the WHO recommendations and challenges.
Findings
Data collected from over 459 Generation Z university students point out the possibility of typologizing them into nine clusters: three consuming fresh fruit and six consuming fresh vegetables. Most cluster members are aware of the value of regular fresh fruit and vegetable consumption in order to maintain health and overall well-being, but the authors also identified a cluster called “urban, but sick humanists at the beginning of their professional careers”, for whom a healthy diet based on fruits and vegetables is not a priority.
Research limitations/implications
Although this research only refers to consumers in the emergent economy Romania, it also allows the delimitation of specific categories which can be utilized by sector stakeholders, in order to identify issues addressed by each cluster member and to find the most appropriate solutions for encouraging/promoting a healthy diet.
Social implications
The paper also raises awareness of the importance of fruit and vegetable consumption in other emerging economies, given the advancement of processed food and reduction of time available to cook healthy dishes.
Originality/value
The results contribute to extending studies conducted on emerging markets concerning fruit and vegetable consumption among Generation Z university students, highlighting the importance of a healthy diet, and the proper targeting of these consumer clusters by fresh fruit and vegetable producers and distributors.

Abstract
Purpose
The paper aims to investigate the standpoints and practices of university members from European developing countries regarding the harnessing of the intellectual capital (IC) within online academic social networks.
Design/methodology/approach
A questionnaire-based survey with 210 university members was conducted, with the indicators adopting prior measurement scales which were further adapted to a network framework.
Findings
The organizational policies and practices relate positively and highly significantly with the valuation of the network-based IC components. Moreover, 63 per cent of the professional and organizational competitiveness of higher education institutions is determined by the exploitation of the IC embedded in online academic networks.
Research limitations/implications
All survey respondents were from the European developing countries, which may limit the general applicability of the findings. Also, the emphasis is laid solely on online academic networks.
Practical implications
This paper brings to the fore both the potential and the state-of-the-art in leveraging the IC of online specialized networks which are indicative of the academic field. When acknowledged as such, the network-based IC is liable to generate substantial competitive advantages at the professional and organizational levels at the same time.
Originality/value
This research adds to the extant literature in two main ways. First, it advances a new construct – network-based IC – in the context of the online academic social networks. Second, it proposes a research model for addressing the network-based IC from a competitive advantage perspective.
