Abstract
Purpose
The present work is a numerical study of a breaking dam problem. The purpose of this paper is to assess the effect of turbulence and surface tension models in the prediction of the interface position in a long-term analysis. Additionally, dimensional effects are analyzed by carrying out both 2D and 3D simulations.
Design/methodology/approach
Finite volume simulations performed with the different models are compared between them and contrasted with numerical results computed using other numerical techniques and experimental data.
Findings
The reported numerical results are in general in good agreement with experimental results available in the literature. They are also consistent with numerical solutions of other authors obtained using different numerical techniques. The results show that the laminar simulations exhibit strong mesh size dependency, while the turbulence models seem to help in producing mesh-independent solutions. Surface tension modeling does not seem to play a relevant role in the interface evolution.
Practical implications
Model validation.
Originality/value
The value of the present work encompass the comparison of different flow conditions used to simulate a free surface problem and their validation by contrasting numerical results with experiments. Also, the results shown in the present work are a contribution to the understanding of the role of some specific aspects of the models in the simulation of the proposed problem.

Abstract
Purpose
This study explores the evolving role of preprint servers within the scholarly communication system, focusing on their relationship with peer-reviewed journals. As preprints become more common, questioning and understanding their future role is critical for maintaining a healthy scholarly communication ecosystem. By examining the values, concerns and goals of preprint server managers, this study highlights the significant influence these individuals have in shaping the future of preprints.
Design/methodology/approach
A qualitative, interview-based approach was used to gather insights from preprint server managers on their roles, challenges and visions for the future of preprints within the broader scholarly communication system.
Findings
The findings point to a lack of consensus on how preprint servers and journals should interact and to diverging views on how the certification and curation functions are best performed and by whom. Concerns about credibility and long-term financial sustainability are increasingly driving independent and community-run preprint servers to align more closely with journals, potentially undermining the disruptive and emancipatory potential of preprints.
Originality/value
This study is the first to examine the relationship between preprints and journals from the perspective of preprint server managers in the later stages of the COVID-19 pandemic. It sheds light on how preprint servers are navigating external pressures and market dynamics, how they are seeking to establish credibility and trust, and how, in doing so, they are reshaping the core functions of scholarly communication.

Abstract
Purpose
Healthcare organizations have addressed current error issues by adopting quality programs, which usually include strategic human resource management (HRM). However, little research has focused on the determinants of successful quality programs at healthcare organizations. The purpose of this paper is to examine the centrality of strategic HRM for addressing healthcare errors, error reduction barriers, quality management processes and practices, quality program results, and competitive advantage.
Design/methodology/approach
The methodology of this study involves the analysis of questionnaire data from the quality and/or risk directors of 587 US hospitals by factor analysis and regression analysis.
Findings
The findings focus on highly statistically significant relationships of strategic HRM with antecedent healthcare error sources, error reduction barriers, and quality management processes and practices, as well as the strategic HRM consequences of perceived quality program results and sustainable competitive advantage.
Research limitations/implications
The limitations of perceptual data and common method variance are checked. Future research could investigate international effects.
Practical implications
The practical implications are that hospital errors can be successfully addressed with effective strategic HRM, quality management processes, and quality management practices.
Originality/value
The original contribution of this paper is the centrality of strategic HRM as a determinant of successful quality programs at healthcare organizations.

The purpose of this paper is to define the integration capability dimensions and create a model for self-assessing the integration capability in inter-organizational projects.
Abstract
Purpose
The purpose of this paper is to define the integration capability dimensions and create a model for self-assessing the integration capability in inter-organizational projects.
Design/methodology/approach
A theoretical construct of, referred in this study as integration capability framework is elaborated following a systematic literature review. Thereafter, an integration capability self-assessment model, based on maturity thinking, is derived from the theoretical framework. The self-assessment model is further developed and tested for validity within five inter-organizational project networks in cooperation with industry practitioners, representing construction, industrial engineering, and mining sectors.
Findings
The results show that inter-organizational projects can use the developed model in self-assessing the maturity levels of various integration mechanisms, thus the state of integration capability at any point in time during inter-organizational projects.
Originality/value
This study is an attempt to identify how the integration capability dimensions can be self-assessed in inter-organizational projects, through the maturity levels of various integration mechanisms. The results offer insights for both academics and project management practitioners.

This paper aims to examine how project managers frame variability for categorised risk factors on enterprise resource planning (ERP) projects.
Abstract
Purpose
This paper aims to examine how project managers frame variability for categorised risk factors on enterprise resource planning (ERP) projects.
Design/methodology/approach
Weighting and selection of the risk factors was undertaken based on an analysis of data (using PASW17), obtained from a random sample of 307 ERP project managers working in Thailand.
Findings
The findings suggest that: framing of variability for categorised risk factors in ERP projects is not necessarily culturally bound; both “internal” and “external” risk factors did have a strong impact on ERP project success; and the impact of the degree of inter‐relationships between critical risk and success factors may influence the success of a ERP project.
Practical implications
The authors anticipate that the results will stimulate future research in this area as well as raise the profile of critical success factors for ERP implementation, particularly in developing countries.
Originality/value
The study contributes to a better understanding of the viewpoint of consultants on critical success factors for ERP implementation in the context of a developing country.

Abstract
Purpose
This paper aim to propose a model of analysis that justifies gamification as an adequate tool to improve the design of services through the human centered design (HCD) methodology.
Design/methodology/approach
The present study is a conceptual contribution. Based on the information provided by the academic literature on the design of services, HCD and gamification, the suitability of the proposed model is justified to help the servitized companies to improve the design of their services.
Findings
There is a gap in the academic literature about how a servitized company develops its service design process; consumers demand experiences through services; involving consumers in the co-creation of value and co-design of services can guide servitized companies to achieve success with servitization; gamification is an effective tool as a relational marketing strategy.
Research limitations/implications
The review of the literature carried out in this paper provides a solid theoretical basis for future researchers in the area of servitization, service design and relational marketing. However, given the conceptual nature of the research, it is necessary to validate empirically the proposed model.
Practical implications
The proposed model can be useful as a reference for manufacturing companies to guide their servitization process. The study extends the debate on how to integrate the design of services by presenting a model of development based on gamification.
Originality/value
Having knowledge of the end-user is essential throughout the service design process and gamification can be achieved as a HCD technique.

Abstract
Purpose
Lactobacillus rhamnosus GG, a probiotic of human origin, known to have health beneficial effects can be exposed to osmotic stress when applied in food production as important quantities of sugars are added to the food product. The aim of this study is to assess the mode of action of non‐electrolytes stress on its viability.
Design/methodology/approach
Investigations were carried out on stationary phase cells treated with 0‐1.5M sugars, by means of flow cytometric method (FCM) and plate enumeration method. Osmotically induced changes of microbial carboxyfluorescein (cF)‐accumulation capacity and propidium iodide‐exclusion were monitored. The ability of the cells to extrude intracellularly accumulated cF upon glucose energization was ascertained as an additional vitality marker, in which the kinetics of dye extrusion were taken into consideration as well. Sugar analysis by HPLC was also carried out.
Findings
The results of FCM analysis revealed that with sucrose, only cells treated at 1.5M experienced membrane perturbation but there was a preservation of membrane integrity and enzymatic activity. There was no loss of viability as shown by plate counts. In contrast, the majority of trehalose‐treated cells had low extent of cF‐accumulation. For these samples a slight loss of viability was recorded on plating (logN/No ∼ −0.45). At 0.6M, cells had similar extrusion ability as the control cells upon glucose energization. However, 20 per cent of sucrose‐treated cells and 80 per cent of trehalose‐treated cells extruded the dye in the first 10min.
Originality/value
This finding pointed out the importance of trehalose to enhance the dye extrusion activity, which is regarded as an analogue of the capability of cells to extrude toxic compounds. Sugars exert different effects on the physiological and metabolic status of LGG but none caused a significant viability loss. LGG can be a choice probiotic bacterium in sugar‐rich food production e.g. candies, marmalade etc., in which exposure to high osmotic pressure is be expected.

Abstract
Purpose
The purpose of this paper is to explore the relationships between best human resource management (HRM) practices, knowledge management (KM), organization learning and organizational capabilities (OC) and their impact on organizational performance. The proposed framework intends to add to the understanding of the specific processes that mediate between best HRM practices and organizational performance.
Design/methodology/approach
A range of relevant literature is explored and a conceptual model is proposed and discussed.
Findings
This paper proposes an answer to “how” best HRM practices can influence performance. It is suggested that KM and organizational learning (OL) play their own unique role in creating OC, which lead to superior performance.
Practical implications
The paper can help human resource managers to understand better the importance of OL and KM processes and the way best HRM practices, through the integration of these two processes, lead to superior and sustainable performance.
Originality/value
This paper attempts to shed some light on the processes through which HRM practices influence performance. The proposed conceptual framework is an original, complete model that will hopefully contribute towards the enrichment of the relevant literature. Moreover, it clarifies relevant terms and their relationship that seem to be surrounded by ambiguity.

Abstract
Purpose
Research findings provide the professional community with knowledge that enables to better understand healthcare interventions. Many authors point out that whilst these findings are valued, the findings are not always translated into healthcare practise. The purpose of the paper is to assess the applicability of the essential elements of an integrated palliative care system (IPCS) found in research into the practise of Osona Palliative Care System (OPCS).
Design/methodology/approach
The study used a qualitative methodology with a case study design. In total, 24 health professionals were interviewed in Osona for the research, and the results were analysed using deductive content analysis.
Findings
The study concludes that research findings can better be translated into specific contexts by incorporating the needs and characteristics of the system. The process could be a strategy for bridging the research–practise gap.
Originality/value
Combining the findings from the study and the findings found in the literature reviewed led to the creation of the IPCS-elements-blended model of research and practise. Such a kind of mixed model could be used in other studies seeking to overcome the research and practice gap.
