The analysis of Hermite factor of BKZ algorithm on small lattices

Lattice cryptography is one of the promising directions in modern cryptography research. Digital signatures and key encapsulation mechanisms on lattices have already been used in practice. In the future, such quantum-resistant transformations on lattices replace all standards that are not resistant to attacks on quantum computers. This makes the analysis of their security extremely relevant. Analysis of the security of cryptographic transformations on lattices is often reduced to the estimation of the minimum block size in the lattice reduction algorithm. For the expansion of small vectors, a reduction algorithm can be obtained for a given block size, the GSA model is often used, which uses the so-called Hermitian factor to predict the size of the vectors that the lattice reduction algorithm can obtain given the parameters. Asymptotic formulas have been developed to evaluate it in practice, but the question of their accuracy on cryptographic lattices has not been fully investigated. The work obtained estimates of the accuracy of the existing asymptotic estimates of the Hermite factor for lattices of sizes 120, 145, 170 for the classical BKZ algorithm. Research was conducted using the fpylll library. It was shown that the existing estimators are equivalent from a practical point of view and have a sufficiently small root mean square deviation from the true values. A formula was obtained that binds the root-mean-square error of approximation of the Hermit factor to the cryptographic parameters of lattices. The obtained results are useful for refining the security assessments of existing cryptographic transformations.

Short-time and long-time dynamics of the zeolite films in the light of alternative diffusion models

Analysis of the dynamics of diffusion of two mixtures of hydrogen and heavier components through a flat zeolite film was carried out. The concepts of short-time and long-time dynamics were introduced. They derive from the observation of temporal trajectories obtained by applying abrupt perturbations of concentrations on one side of the membrane.An alternative description of the diffusion dynamics was proposed compared to the commonly accepted model that employs a matrix of thermodynamic factors Γ. In this way, the difficulty of analytical determination of this matrix for more complex adsorption equilibria was eliminated.The model equations were expressed in a matrix form, which enables its easy extension to any number of components. The proposed research methodology was illustrated using an example of diffusion of two selected mixtures, i.e. {H2, n-C4H10} and {H2, CO2} in silicalite-1. These gaseous mixtures have applications in specific technological processes.The two models were used to perform quantitative benchmarking of short-time and long-time dynamics of flat zeolite membranes. The assumed boundary conditions correspond to a semi-batch Wicke-Kallenbach diffusion cell. It was demonstrated that the phenomena occurring in short-time and long-time diffusion represent two different dynamic features important from a scientific and practical point of view.A quantitative measure for degree of confinement was proposed based on dynamic adsorption-desorption hysteresis.

‘Providing a Layman's Guide to the Scheme’: Museum Computing, Professional Personas and Documentary Labour in the United Kingdom, 1967–1983

Abstract Between the 1960s and early-1980s the museum sector in the United Kingdom (UK) was rapidly professionalised and systematised. A crucial moment in this transition was the creation in 1967 of the Information Retrieval Group of the Museums Association (IRGMA), and the subsequent launch of its system for the machine encoding and communication of museum catalogue records. The rise of IRGMA marked an inflection point in museological practice and the normalisation of computerised work within the UK museum profession, a moment when the desire for a ‘layman's guide to the scheme’ began to give way to new professional personas and forms of documentary labour. This article asks how cultures of museology and professional labour shifted in response to IRGMA. It argues that between the late 1960s and mid-1980s both the implementation of and the debate around computerised cataloguing disrupted the function of UK museums and how museum professionals imagined their labour. And by tracing the emergence of these cultures and their intersections with professional identity and labour practices, this article seeks to tease out the ways museum history can resonate with wider narratives of labour, expertise and technological innovation in contemporary British history.

Wearable Devices Based on Bioimpedance Test in Heart-Failure: Design Issues.

Heart-failure (HF) is a severe medical condition. Physicians need new tools to monitor the health status of their HF patients outside the hospital or medical supervision areas, to better know the evolution of their patients' main biomarker values, necessary to evaluate their health status. Bioimpedance (BI) represents a good technology for sensing physiological variables and processes on the human body. BI is a non-expensive and non-invasive technique for sensing a wide variety of physiological parameters, easy to be implemented on biomedical portable systems, also called "wearable devices". In this systematic review, we address the most important specifications of wearable devices based on BI used in HF real-time monitoring and how they must be designed and implemented from a practical and medical point of view. The following areas will be analyzed: the main applications of BI in heart failure, the sensing technique and impedance specifications to be met, the electrode selection, portability of wearable devices: size and weight (and comfort), the communication requests and the power consumption (autonomy). The different approaches followed by biomedical engineering and clinical teams at bibliography will be described and summarized in the paper, together with results derived from the projects and the main challenges found today.

Assessment of Ground Control Points Positional Shift and Management Practices: Evidences from Assosa Town, Western Ethiopia

This study assesses the positional shift of existing control points and management practices found in and around Assosa town. The static GPS measurement technique was used as an independent source and a point wise method were used to assess the positional shift and accuracy level evaluation. Due to unavailability of local CORS station, two first order GCPs were used as a reference during static GPS measurement. After measurement was conducted depending on the baseline length between control point marks, the STC desktop software and online CSRS-PPP post processing technique was used. Thus, the positional accuracy of selected GCPs of STC Post processing technique has a mean error of 0.324 m and whereas the GCPs of CSRS-PPP has a mean error of 0.571 m. Horizontal distance error obtained with the STC differential technique is ranging from 0 to 0.83 m which is inconsistent relative to the range 0.437 m to 0.815 m obtained from online CSRS-PPP solution. The positional accuracy of GCPs was also assessed using horizontal distance error of both processed techniques. The positional accuracy of GCPs at 95% confidence level is between -0.117 m and 0.765 m with STC and between 0.395 m and 0.747 m in online CSRS-PPP solution. Based on the result, the accuracy level of existing GCPs found in Assosa town, does not meet the FGDC accuracy. This was mainly associated with perception of communities on ground control point management activities. The study revealed almost low communities practice and control point management responsiveness. Finally, study suggested that there should be participatory guidance to establish and manage the ground control points.

Design concept of intelligent integrated control system for neutral beam injection

Abstract Due to the specificity of neutral beam injection (NBI) system, the control of its actual physical system is achieved by the integrated control system (ICS). The current NBI ICS adopts a distributed design structure to balance the system load, which is also the mainstream system design and architecture model of ICS around the world. However, from a practical point of view, the distributed system architecture is not perfect. In the long run, upgrading the system intelligence and automation capabilities is an inevitable choice for the future, so it is necessary to explore ways to transform and upgrade the ICS. At present, Internet of Things (IoT), as an important part of the new generation information technology, can realize the control of everything through data exchange. This is because on the one hand, IoT has wide compatibility and powerful scenario-based capabilities, it not only has the advantages and characteristics of distributed design, but also can pull the NBI subsystems into the same level scenario and lay the foundation for the further construction of digital NBI; on the other hand, the intervention of artificial intelligence makes IoT have some new typical characteristics such as intelligent sensing, ubiquitous connectivity, precise control, digital modeling, real-time analysis and iterative optimization, which is enough to pull the current NBI ICS into a new intelligent control era. Finally, it is worth mentioning that due to its inherent design structure and functional characteristics, ICS tends to be broadly generic, so it is not exclusively used for NBI operation in nuclear fusion, and it can provide some insight into other application areas.

The right care in the right place: a scoping review of digital health education and training for rural healthcare workers

BackgroundDigital health offers unprecedented opportunities to enhance health service delivery across vast geographic regions. However, these benefits can only be realized with effective capabilities and clinical leadership of the rural healthcare workforce. Little is known about how rural healthcare workers acquire skills in digital health, how digital health education or training programs are evaluated and the barriers and enablers for high quality digital health education and training.ObjectiveTo conduct a scoping review to identify and synthesize existing evidence on digital health education and training of the rural healthcare workforce.Inclusion criteriaSources that reported digital health and education or training in the healthcare workforce in any healthcare setting outside metropolitan areas.MethodsWe searched for published and unpublished studies written in English in the last decade to August 2023. The databases searched were PubMed, Embase, Scopus, CINAHL and Education Resources Information Centre. We also searched the grey literature (Google, Google Scholar), conducted citation searching and stakeholder engagement. The JBI Scoping Review methodology and PRISMA guidelines for scoping reviews were used.ResultsFive articles met the eligibility criteria. Two case studies, one feasibility study, one micro-credential and one fellowship were described. The mode of delivery was commonly modular online learning. Only one article described an evaluation, and findings showed the train-the-trainer model was technically and pedagogically feasible and well received. A limited number of barriers and enablers for high quality education or training of the rural healthcare workforce were reported across macro (legal, regulatory, economic), meso (local health service and community) and micro (day-to-day practice) levels.ConclusionsUpskilling rural healthcare workers in digital health appears rare. Current best practice points to flexible, blended training programs that are suitably embedded with interdisciplinary and collaborative rural healthcare improvement initiatives. Future work to advance the field could define rural health informatician career pathways, address concurrent rural workforce issues, and conduct training implementation evaluations.Review registration numberOpen Science Framework: https://doi.org/10.17605/OSF.IO/N2RMX.

Summary of the 2023 international evidence-based guideline for the assessment and management of polycystic ovary syndrome: an Australian perspective.

The Australian-led 2023 International evidence-based guideline for the assessment and management of polycystic ovary syndrome was based on best available evidence, clinical expertise and consumer preference. It followed best practice, involved extensive evidence synthesis and applied relevant frameworks across evidence quality, feasibility, acceptability, cost and implementation. Thirty-nine societies and organisations covering 71 countries were engaged. The evidence in the assessment and management of polycystic ovary syndrome (PCOS) has generally improved in the past five years, but remains of low to moderate quality. The technical evidence report, 52 systematic reviews and analyses (approximately 6000 pages) underpin 77 evidence-based and 54 consensus recommendations, with 123 practice points. Changes include: refinement of individual diagnostic criteria, a simplified diagnostic algorithm and inclusion of anti-Müllerian hormone levels as an alternative to ultrasound in adults only, and differentiation of adolescent and adult criteria; strengthening the recognition of broad features of PCOS including metabolic effects, cardiovascular disease, dermatological symptoms, sleep apnoea, a high prevalence of psychological features and a high risk of adverse pregnancy outcomes; emphasising the poorly recognised, diverse burden of disease, the vital need for greater health professional education, evidence-based patient information, improved models of care, shared decision making and research efforts to improve patient experience; maintained emphasis on healthy lifestyle, emotional wellbeing and quality of life, with awareness and consideration of weight stigma; and emphasising evidence-based medical therapy and cheaper and safer fertility management. The 2023 guideline is approved by the National Health and Medical Research Council and provides clinicians and patients with clear advice on best practice in a common and neglected condition, based on the best available evidence, expert multidisciplinary input and consumer preferences. It provides vital, extensive patient and provider resources to enhance evidence-based care. The full guideline is available at www.monash.edu/medicine/mchri/pcos/guideline.

The level of expression of HPV16 early transcripts is not associated with the natural history of cervical lesions.

The natural history of cervical cancer is closely linked to that of high-risk human papillomaviruses (HPV) infection. It is recognized that upon HPV DNA integration, partial or complete loss of the E2 open reading frame precludes expression of the corresponding protein, resulting in upregulation of the E6 and E7 viral oncoproteins. To better characterize HPV16 infection at the cervical level, viral load, viral DNA integration, and viral early transcript expression (E2, E5, and E6) were analyzed in a series of 158 cervical specimens representative of the full spectrum of cervical disease. Overall, the frequency of early transcript detection varied from 45% to 90% and tended to increase with lesion severity. In addition, the levels of E2, E5, and E6 transcript expression were slightly higher in high-grade lesions than in cervical specimens without abnormalities. Notably, early transcript expression was clearly associated with viral load, and no inverse correlation was found between the expression of E2 and E6 transcripts. No clear association was found between early transcript expression and HPV16 DNA integration, with the exception that samples with a fully integrated HPV16 genome did not harbor E2 or E5 transcripts. In conclusion, early HPV16 transcript expression appears to be associated with viral load rather than lesion grade. From a practical point of view, quantification of HPV16 early transcripts is difficult to translate into a relevant biomarker for cervical cancer screening.

시민행동 압력이 공무원의 조직시민행동에 미치는 영향 - 비선형 관계를 중심으로

This study aims to clarify the effect of Citizenship Pressure (CP) on Organizational Citizenship Behavior (OCB). CP is a complex concept that induces OCB while also causing negative effects such as work-family conflict and stress. We applied Social Learning Theory and Conservation of Resource Theory to capture these dynamics. OCB towards Individuals (OCBI) and OCB towards the Organization (OCBO) were set as dependent variables, CP was set as the independent variable, and control variables were established with factors that have been verified to affect OCB. Data were obtained through a survey of 400 public officials in the Republic of Korea. The results showed that with a weak level of CP, both OCBI and OCBO decreased, but as the level of CP increased beyond a certain point, both OCBI and OCBO increased, illustrating a U-shaped effect. Specifically, the inflection point where CP’s effect turns from negative to positive occurred sooner in OCBI than in OCBO. Therefore, this study further claims that the direction of the effect of CP on OCB can differ according to its degree and the types of OCB, which has been predominantly discussed in terms of a linear relationship. Theoretical implications and practical points are suggested based on the results.

Building a model of heating an oil tank under the thermal influence of a spill fire

The object of this study is the process of liquid combustion in a spill, and the subject of research is the distribution of temperature along the wall and roof of a vertical steel tank that is heated under the thermal influence of a spill fire. The heat balance equation for the wall and roof of the tank with oil product was constructed. The assumption of a small thickness of the wall and roof of the tank relative to its linear dimensions makes it possible to move to two-dimensional differential equations of the parabolic type. The equations take into account the radiative heat exchange with the flame, the environment, the internal space of the tank, as well as the convective heat exchange with the surrounding air, the vapor-air mixture, and the liquid inside the tank. Using the methods of similarity theory, estimates of the coefficients of convection heat exchange of the outer surface of the tank with the surrounding air and the inner surface with the vapor-air mixture and liquid in the tank in the conditions of free convection were constructed. The application of the finite difference method for solving the heat balance equations has made it possible to derive the temperature distribution on the surface of the tank at an arbitrary moment in time. It is shown that the value of the coefficient of convection heat exchange of the liquid exceeds the corresponding value for the air-vapor mixture by (1÷2) orders of magnitude. As a result, the part of the wall located below the oil product level is heated to a temperature of (80÷230) °C depending on the viscosity of the liquid. This occurs despite the fact that the value of the mutual radiation coefficient reaches its maximum value at the lower part of the wall. From a practical point of view, this means that the part of the wall above the level of the oil product in the tank can reach dangerous temperature values, and it should be cooled first. The constructed model of tank heating also enables determining the limit time for the start of cooling of the tank.

Identification of the oxidation and hydrolysis products content influence on the rapeseed oil oxidation induction period

The object of the study is the dependence of the induction period of rapeseed oil on the content of oxidation and hydrolysis products. A feature of the work is determining the approximation dependence of the induction period of accelerated oxidation of refined rapeseed oil on the content of primary oxidation products and free fatty acids. This is useful when predicting the shelf life of refined rapeseed oil. It was determined that both factors negatively affect the oxidation stability of refined rapeseed oil. An increase in the peroxide value decreases the induction period of model oil samples by 32.8512 units for each additional mmol ½ O/kg. In turn, increasing the acid value of oil samples reduces the induction period by 19.8424 units for each additional mg KOH/g. Different oxidation dynamics of model samples of refined rapeseed oil with tocopherol were revealed, depending on the concentration of primary oxidation and hydrolysis products. The obtained data are explained by the fact that the primary lipid oxidation products are unstable and quickly decompose to form free radicals. These radicals initiate further lipid oxidation, resulting in reduced oil quality. In addition, free fatty acids are more reactive than triglycerides and are more easily oxidized. A feature of the obtained results is the possibility of modeling processes that affect the oxidation stability of refined rapeseed oil. From a practical point of view, the research results allow initiating measures to maintain the safety of oil-containing food products based on refined rapeseed oil. An applied aspect of using the scientific results is the possibility of rationalizing the storage conditions of refined rapeseed oil to maximize its shelf life and increase competitiveness

Fast Reaction of the Prussian Blue Based Nanozyme "Artificial Peroxidase" with the Substrates: Pre-Steady-State Kinetic Approach.

This letter introduces the pre-steady-state kinetic approach, which is traditional for evaluation of elementary constants in molecular (enzyme) catalysis, for nanozymes. Apparently, the most active peroxidase-mimicking nanozyme based on catalytically synthesized Prussian Blue nanoparticles has been chosen. The elementary constants (k1) for the nanozymes' reduction by an electron-donor substrate (being the fastest stage according to steady-state kinetic data) have been determined by means of stopped-flow spectroscopy. These constants have been found to be dependent on both the size of the nanozyme and the reducing substrate redox potential. For the smallest nanozymes (32 nm in diameter), log(k1) linearly decays with an increase of the substrate redox potential (cotangent value ≈125 mV). On the contrary, for the largest nanozymes with a diameter above 150 nm, k1 is almost independent of it. Moreover, for the substrate with the lowest redox potential (K4[Fe(CN)6]), the rate constant under discussion (k1) is almost independent of the nanozymes' size. Perhaps, the rate of the intrananozyme electron transfer causing bleaching becomes comparative or even lower than that of the nanoparticle interaction with the fastest substrate. Anyway, the elementary constant of nanozyme reduction with potassium ferrocyanide (k1) reaches the value of 1 × 1010 M-1 s-1, which is 3-4 orders of magnitude faster than for enzymes peroxidases. The obtained results obviously demonstrate that the pre-steady-state kinetic approach is able to discover novel advantages of nanozymes from both fundamental and practical points of view.

Trade policy revisited: how government support initiatives affect international performance in SMEs?

PurposeThis paper aims to understand how government support initiatives can enhance the international performance of small and medium-sized enterprises (SMEs). To address the gap of literature, this paper employed three theoretical lenses to examine both of direct and indirect relationships between two main constructs.Design/methodology/approachThis empirical study is based on data collected from Armenian exporter SMEs. The data collection utilized a random sampling approach, resulting in 138 fully completed questionnaires, yielding a response rate of 28.4%, comparable to previous studies in international business research. This sample includes firms from three main sectors: agriculture, manufacturing and services, reflecting the structure of Armenia's international trade. Relationships were examined using Partial Least Squares Structural Equation Modeling (PLS-SEM).FindingsThe results of this study indicate that government support initiatives lack a direct impact on international performance, while positing instead an indirect connection between the two constructs through strategic capability and institutional pressures.Originality/valueThe results of this study contribute to the international business literature in several ways. First, it surpasses the conventional examination of government support on firm performance by delving into both the direct and indirect relationships between these constructs. Second, it reveals that not all theoretical viewpoints hold equal strategic importance in explaining the internationalization of SMEs. From the practical point of view, findings help policymakers to maximize a country's export capacity by implementing tailored initiatives, considering the unique requirements of SMEs.

Difficulties among Teachers' Emotional Regulation: Analysis for the Development of Student Well-Being in Chilean Schools.

Emotional regulation, a process that involves detecting and evaluating physiological signals in response to stressful events, is a crucial aspect of preparing students for school and ensuring teachers' effectiveness, stress management, and job satisfaction. This research, which adopted a quantitative approach, used a non-experimental comparative and cross-sectional design with a non-probabilistic sample by convenience. The study involved the participation of n = 1321 teachers (n = 125 preschool education; n = 645 primary education; n = 417 secondary education; n = 134 higher education). The results revealed significant differences in the total scores of emotional regulation difficulty between teachers at the higher education level and primary and secondary school teachers, with the latter group showing higher levels of difficulty. The findings suggest that the impact of emotional regulation difficulties affects professional performance, highlighting the importance of interventions aimed at improving teachers' self-efficacy, resilience, and emotion regulation to reduce emotional exhaustion. From a practical point of view, our findings underline the importance of integrating emotional regulation training into pre-service teacher education and continuous teacher professional development programs. This could improve relational dynamics between students and teachers, fostering an environment conducive to teaching and learning processes.

Stroke in women: anticoagulation in a complicated puzzle

Stroke is the third leading cause of death and the most important reason for disability. It is worth noting that 60% of all stroke deaths involve women. This review aims to revise the prothrombotic hemostatic alterations in hypertension along with the often-overlooked role of depression and the job strain of the homemakers’ condition proven to be risk factors for stroke. Moreover, the impact of atrial fibrillation and the related oral anticoagulation with either vitamin K antagonists (VKA) or direct oral anticoagulants (DOAC) in women will be discussed. Another point is that women are treated less with anticoagulants than men. Underdosing is also frequent. In our opinion, defensive medicine represents the basic bias, which plays a major role in this contest. The main reasons are the overlooking of the increased cardioembolic risk in women, the fear of an increased bleeding risk, and the wrong concept regarding a hypothetical higher frailty. In conclusion, from a practical point of view, thrombosis centers should consider all these factors when a woman shows a bad quality of anticoagulation with VKA or a poor adherence to DOAC treatment. Underdosing should also be carefully avoided. We hope that the sex gap in terms of inadequate treatment and inclusion in clinical trials will be covered in the future. Lastly, defensive medicine should be strongly discouraged.

Linguistics for Translators

What makes a translator truly exceptional? Is it their grasp of both source and target languages, or perhaps their sensitivity to cultural nuances? Linguistics for Translators by Ali Almanna and Juliane House delves into these questions with the ambition to bridge the gap between linguistic theory and translation practice. This ambitious textbook does not just present linguistic concepts but intricately weaves them into the fabric of translation studies, making it an indispensable resource “for a diverse audience, including students of translation and linguistics, practising translators, and readers from neighbouring disciplines who are interested in the subject” (Alamnaa and House, 2024, p.4). Almanna and House (2024) begin with a captivating premise: understanding the intricate mechanisms of language is fundamental for any translator. They set the stage by discussing why linguistic knowledge is crucial, not just as an academic exercise, but as a practical toolkit for enhancing translation quality. “Our aim with Linguistics for Translators is to emphasize that the linguistic dimension of translation cannot be overlooked,” Almanna and House (p.1) assert, highlighting the book’s relevance from the outset. This approach aligns with the views of Hatim and Munday (2004), who also emphasize the significance of linguistic competence in translation. The book’s twelve chapters cover a broad spectrum of linguistic areas, each crucial for the aspiring translator. Each chapter is meticulously designed to build on the previous one, from the basics of phonetics and phonology to the complexities of cognitive linguistics. The authors provide an engaging overview of linguistics, linking it directly to translation through practical exercises and discussion points. They introduce linguistic universals and translation universals, sparking curiosity about their application in real-world translation. This discussion echoes the foundational work of Catford (1965), who first articulated the need for linguistic theory in translation.

Parasitological Examination of the Digestive System of Wild Boar from a Practical Point of View-Endoparasitological Sampling under Field Conditions.

From 2015 to 2023, we conducted a comprehensive study in the 11,893-hectare hunting area managed by the Marcal-Bitvaközi Hunting Company, characterised by its substantial wild boar population. The research was carried out across various settings, including a free-range wild boar garden during large-scale hunts and free-living areas during individual hunts. We examined 216 wild boars in total, with 173 individuals from free-living areas and 43 from free-range areas. Throughout the sample collection process, we encountered numerous technical challenges that are infrequently detailed in the professional literature, often mentioned only tangentially. This oversight in existing publications neglects the significance of addressing field sampling difficulties, which are crucial for ensuring the precision and accuracy of research. This paper details the equipment requirements, sampling methodologies, and practical solutions to streamline fieldwork. While our primary focus was on endoparasitic infections of the stomach and small intestine, the described methodologies and findings are broadly applicable to research involving all internal organs.

Inter-organisational cooperation networks: a strategy for the knowledge-sharing and performance of higher education institutions

PurposeThis study aims to present how an inter-organisational cooperation network can contribute to the competitive performance of higher education institutions (HEI) and also to students’ academic performance. The intention is also to examine how knowledge-sharing processes should develop to meet the needs of maintaining cooperation networks.Design/methodology/approachThis study adopts a qualitative approach, using the case study (network) method. The data were collected through semi-structured interviews, group interviews and documentary analysis. The convenience sampling technique was used. Data analysis was carried out through a data triangulation process.FindingsThe general benefits arising from cooperation networks are encouraging. The HEIs improved not only through creating an environment that supports learning processes and knowledge-sharing efficiently, but also through cooperation between students and lecturers.Practical implicationsThe cooperation network experience studied here can be used by other universities or HEIs as an approach/strategy to launch a cooperation initiative in order to increase levels of knowledge, learning, innovation and competitiveness. The results also help university or HEI leaders to understand the importance of academic cooperation networks, letting them form innovative teaching strategies that stimulate academic and competitive performance, as well as economic growth.Originality/valueThe central elements of originality lie in advancing a new vision of cooperation networks, creating a new, innovative framework that considers the dimensions presented from the theoretical and practical point of view. The framework helps to understand what is necessary for network cooperation to develop and create value for HEIs. Combining different perspectives of the cooperation network inevitably represents a significant innovation.
