Research on Trajectory Planning of Autonomous Vehicles in Constrained Spaces
Authors: Li Yunlong , Li Gang , Wang Xizheng
Published: September 2024

This paper addresses the challenge of trajectory planning for autonomous vehicles operating in complex, constrained environments. The proposed method enhances the hybrid A-star algorithm through back-end optimization. An adaptive node expansion strategy is introduced to handle varying environmental complexities. By integrating Dijkstra’s shortest path search, the method improves direction selection and refines the estimated cost function. Utilizing the characteristics of hybrid A-star path planning, a quadratic programming approach with designed constraints smooths discrete path points. This results in a smoothed trajectory that supports speed planning using S-curve profiles. Both simulation and experimental results demonstrate that the improved hybrid A-star search significantly boosts efficiency. The trajectory shows continuous and smooth transitions in heading angle and speed, leading to notable improvements in trajectory planning efficiency and overall comfort for autonomous vehicles in challenging environments.
Local-Peak Scale-Invariant Feature Transform for Fast and Random Image Stitching
Authors: Li Hao , Wang Lipo , Zhao Tianyun , Zhao Wei
Published: September 2024

Image stitching aims to construct a wide field of view with high spatial resolution, which cannot be achieved in a single exposure. Typically, conventional image stitching techniques, other than deep learning, require complex computation and are thus computationally expensive, especially for stitching large raw images. In this study, inspired by the multiscale feature of fluid turbulence, we developed a fast feature point detection algorithm named local-peak scale-invariant feature transform (LP-SIFT), based on the multiscale local peaks and scale-invariant feature transform method. By combining LP-SIFT and RANSAC in image stitching, the stitching speed can be improved by orders compared with the original SIFT method. Benefiting from the adjustable size of the interrogation window, the LP-SIFT algorithm demonstrates comparable or even less stitching time than the other commonly used algorithms, while achieving comparable or even better stitching results. Nine large images (over 2600 × 1600 pixels), arranged randomly without prior knowledge, can be stitched within 158.94 s. The algorithm is highly practical for applications requiring a wide field of view in diverse application scenes, e.g., terrain mapping, biological analysis, and even criminal investigation.

Published: September 2024

As the energy demand increases, there is a significant expansion and utilization of oil resources, resulting in the inevitable occurrence of environmental pollution. Oil has been identified as a prevalent soil contaminant, posing substantial risks to the soil ecosystems. The remediation of soil contaminated with oil is a formidable undertaking. Increasing evidence shows that chemical washing, a remediation technique employing chemical reagents like surfactants to augment the solubilization, desorption, and separation of petroleum hydrocarbons in soil, proves to be an efficacious approach, but the latest advances on this topic have not been systematically reviewed. Here, we present the state of knowledge about the surfactant-based chemical washing to remediate oil-contaminated soil. Using the latest data, the present article systematically summarizes the advancements on ex situ chemical washing of oil pollution and provides a concise summary of the underlying principles. The use of various surfactants in chemical washing and the factors influencing remediation efficiency are highlighted. Based on the current research status and knowledge gaps, future perspectives are proposed to facilitate chemical washing of oil-polluted soil. This review can help recognize the application of chemical washing in the remediation of oil-polluted soil.

Published: September 2024

Humans are unavoidably exposed to numerous different mutagenic DNA alkylating agents (AAs), but their role in the initiation of cancers is uncertain, in part due to difficulties in assessing human exposure. To address this, we have developed a screening method that measures promutagenic O6-alkylguanines (O6-AlkGs) in DNA and applied it to human DNA samples. The method exploits the ability of the Schizosaccharomyces pombe alkyltransferase-like protein (Atl1) to recognise and bind to a wide range of O6-AlkGs in DNA. We established an Atl1-based slot-blot (ASB) assay and validated it using calf thymus DNA alkylated in vitro with a range of alkylating agents and both calf thymus and human placental DNA methylated in vitro with temozolomide (TMZ). ASB signals were directly proportional to the levels of O6-meG in these controls. Pre-treatment of DNA with the DNA repair protein O6-methylguanine–DNA methyltransferase (MGMT) reduced binding of Atl1, confirming its specificity. In addition, MCF 10A cells were treated with 500 μM TMZ and the extracted DNA, analysed using the ASB, was found to contain 1.34 fmoles O6 -meG/μg DNA. Of six human breast tumour DNA samples assessed, five had detectable O6-AlkG levels (mean ± SD 1.24 ± 0.25 O6-meG equivalents/μg DNA. This study shows the potential usefulness of the ASB assay to detect and quantify total O6-AlkGs in human DNA samples.
Quantum Loop Corrections in the Modified Gravity Model of Starobinsky Inflation with Primordial Black Hole Production
Authors: Saburov Sultan , Ketov Sergei V.
Published: September 2024

A modified gravity model of Starobinsky inflation and primordial black hole production is proposed in good (within 1σ) agreement with current measurements of the cosmic microwave background radiation. The model is an extension of the singularity-free Appleby–Battye–Starobinsky model by the R4 term with different values of the parameters whose fine-tuning leads to the efficient production of primordial black holes on smaller scales with the asteroid-size masses between 1016 g and 1020 g. Those primordial black holes may be part (or the whole) of the current dark matter, while the proposed model can be confirmed or falsified by the detection or absence of the induced gravitational waves with the frequencies in the 10−2 Hz range. The relative size of quantum (loop) corrections to the power spectrum of scalar perturbations in the model is found to be of the order of 10−3 or less, so that the model is not ruled out by the quantum corrections.

Published: September 2024

Cancer is a complex pathological condition associated with substantial rates of mortality and morbidity in both humans and animals. Mammary gland tumors in intact female dogs are the most prevalent neoplasms. Surgical intervention remains the primary treatment choice. Alternative therapeutic options have emerged, with histopathological examination being fundamental to confirm the diagnosis and to decide the best therapy. This research focused on the clinicopathological, immunohistochemical, and cytogenetic aspects of canine mammary tumors (CMTs). Most of the animals were mixed-breed, with the majority being older than seven years, and only 16.7% had been spayed before surgery. Caudal abdominal and inguinal mammary glands were the most affected, with regional mastectomy being the predominant treatment (75.0%). Of all the tumors, 29.1% were benign, while 70.9% were malignant. Complex adenoma was the most common benign tumor, whereas tubulopapillary carcinoma was the most common malignant type. Grade III tumors (17.6%) were the least encountered, while grades I and II exhibited a similar prevalence (41.2%). All the carcinomas were classified as luminal, and cytogenetics analysis demonstrated a high chromosomal instability with significant aneuploidy observed in all cases and polyploidy detected in 62.5%. This study holds significance as canine and human breast cancers share similar characteristics, suggesting that dogs could be a valuable model for human breast cancer research. Further studies with larger sample sizes are needed to enhance our understanding of CMTs.

Published: September 2024

Introdução: A oftalmopatia de Graves é a doença orbitária mais comum e acomete até metade dos pacientes portadores da Doença de Graves. Se trata de uma doença inflamatória autoimune caracterizada pela deposição de imunocomplexos antitireoglobulina nos músculos extraoculares e da órbita. Objetivo: o presente texto visa apresentar uma revisão sintetizada e abrangente do que há de atual na literatura científica sobre a oftalmopatia de Graves, a fim de contribuir não apenas para a ampliação do entendimento desta patologia, como também servir como uma ferramenta para guiar futuras pesquisas e práticas clínicas. Metodologia: os esforços implicados nesta pesquisa, voltaram-se para uma revisão integrativa da literatura. Discussão: A literatura atual tem sugerido que, das condições clínicas que levam à oftalmopatia, uma apresentação clínica rara, porém incapacitante e desfigurante, é o comprometimento ocular associado a alterações no funcionamento da tireoide. Além da oftalmopatia de graves, outras condições clínicas podem cursar com o aparecimento desta comorbidade, como é o caso do câncer de tireoide, em estados hipotireoidianos como a tireoidite de Hashimoto e no hipotireoidismo subclínico. Em um estudo de revisão sistemática, nos pacientes já diagnosticados com oftalmopatia associada à tireoide, encontrou-se prevalência de 86,2% com hipertireoidismo; prevalência de 10,36% com hipotireoidismo; e 7,9% com estados eutireoidianos, seguindo o mesmo padrão em outros estudos.  Conclusão: Com base nos achados desta pesquisa a oftalmopatia de graves é uma doença frequentemente bilateral. Os sintomas mais comuns incluem dor orbital, lacrimejamento, fotofobia, sensação de corpo estranho, visão turva, diplopia e desconforto ao movimentar os olhos. Os fatores de risco para orbitopatia tireoidiana incluem disfunção tireoidiana, tabagismo e tratamento com iodo radioativo. O diagnóstico da doença oftalmológica de Graves é baseado na combinação de critérios clínicos e exames oftalmológicos e de imagem. Como tratamento desta doença, deve ser realizada uma abordagem multidisciplinar a fim de otimizar o manejo e preservar a função visual do paciente.

Published: September 2024

O Transtorno Afetivo Bipolar (TAB) e as doenças cardiovasculares são intimamente relacionadas, sendo as doenças cardiovasculares a principal causa de morte prematura, em relação à população geral, nos indivíduos com bipolaridade. Assim, o presente trabalho tem como objetivo relatar a correlação entre o TAB e doenças cardiovasculares por meio de uma revisão sistemática de literatura. Foi realizada uma busca eletrônica em diversas bases de dados, sendo inclusos 21 artigos publicados em português, inglês e espanhol entre agosto de 2006 a junho de 2023 e que condiziam com o objetivo proposto. No TAB, a morbidade excessiva por doenças cardiovasculares tem etiologia multifatorial, sofrendo influência das condições socioeconômicas dos pacientes, das características inerentes a própria doença que promovem a adoção de comportamentos de risco relacionados à má alimentação, etilismo e tabagismo e dos tratamentos direcionados a ela. O tratamento do TAB é constituído, principalmente, por terapia medicamentosa com estabilizadores de humor e/ou antipsicóticos, medicações que possuem efeitos adversos os quais comprovadamente podem gerar elevação do risco cardiovascular e propiciar o surgimento de doenças cardiovasculares. Os estabilizadores de humor destacam-se pelo seu potencial de ganho de peso, em especial o lítio e o ácido valpróico, e embora as desordens no metabolismo dos lipídios e da glicose não sejam frequentemente causadas por essas medicações, o ganho de peso secundário a elas pode contribuir para o surgimento de hiperglicemia, diabetes e dislipidemia. Levando em consideração os antipsicóticos atípicos, sabe-se que eles possuem capacidade comprovada de elevação do risco cardiovascular, visto que podem causar ganho de peso, hiperglicemia, diabetes e dislipidemia de forma isolada. Apesar disso, estudos recentes mostram que os as medicações mais novas dessa classe, como o aripiprazol e a ziprazidona, parecem apresentar pouco ou nenhum efeito deletério sobre o metabolismo lipídico e glicídico. A correlação entre o TAB e as doenças cardiovasculares demonstra a constante negligência médica das comorbidades físicas em pacientes psiquiátricos e a maior necessidade de vigilância em relação ao aumento do risco cardiovascular e surgimento de doenças cardiovasculares nesses indivíduos. Assim, diante do exposto, percebe-se a impossibilidade de atribuir a carga de doenças cardiovasculares em pacientes com TAB à um único fator, o que reitera a maior necessidade de novos estudos nessa população.

The Role of Stakeholders in Crowdfunding Success: Insights From a Systematic Literature Review
Authors: Maraglino Misciagna Maurizio
Published: September 2024

In the last decade, crowdfunding has emerged as a pivotal innovation in financial and entrepreneurial ecosystems, reshaping how projects are funded and how investors interact with emerging ventures. This paper conducts a systematic review of crowdfunding literature from 2010 to 2020 using the PRISMA method, focusing on the roles and interactions of diverse stakeholders within the crowdfunding framework. By integrating stakeholder theory, the study examines how alignment of stakeholders’ interests—ranging from founders and backers to crowdfunding platforms and regulatory bodies—contributes to the success of crowdfunding initiatives. The review highlights the evolution of crowdfunding, not only as a funding tool but also as a community-building platform that leverages Web 2.0 technologies to foster interactive engagement. Findings suggest that successful crowdfunding requires more than financial transactions; it necessitates a robust ecosystem where stakeholders’ expectations and contributions are clearly understood and managed. The study contributes to academic and practical understandings of crowdfunding by delineating the dynamics between various stakeholders and providing insights into how these relationships influence the outcomes of crowdfunding campaigns. Future research directions are suggested, including deeper exploration of the regulatory impacts and the long-term sustainability of crowdfunding as a finance model.
Knowledge Management Meets Artificial Intelligence: A Systematic Review and Future Research Agenda
Authors: Bolisani Ettore , Nakash Maayan
Published: September 2024

In the complex mosaic of the digital age, the tactical incorporation of artificial intelligence (AI) within knowledge management (KM) is revealed as a central business component of technology management. The current study aims to clarify the intersection between KM and AI in organizational contexts. Specifically, this paper represents a preliminary step to investigate the potential impacts of AI on KM research and practice. Building on a database we created from Scopus, we shine a spotlight on trends in pertinent peer-reviewed scientific articles published in the last decade (2013-2023) on the KM-AI nexus. In addition, the paper presents an extended systematic analysis of literature, which synthesizes theoretical and empirical works conducted to date on this topic. Through a review of the available studies, we strive to shed light on effective KM frameworks and strategies in the era of AI. As extant research in the literature is largely theoretical, we propose to conduct empirical research on AI technologies in core KM processes such as acquisition, documentation, sharing, and application of knowledge. In addition, we recognize that the challenges and barriers to implementing AI in KM systems are not in focus and deserve to ignite further research. The anticipated contributions from such inquiries promise not only to augment the corpus of knowledge within the discipline, but also to furnish KM practitioners with the insights necessary for the crafting of efficacious systems. This research marks the advent of a transformative scholarly epoch, wherein the harmonious integration of KM and AI emerges as the bedrock of organizational ingenuity and strategic acumen. It distinguishes itself from prior works by pinpointing knowledge gaps in the synergy between disciplines and underscores the imperative for future research to bridge these lacunae.
Using T2-Capability Profile Modelling to Anticipate Change and Development: Bridging the Industry and Higher Education Views
Authors: Saukkonen Juha , Sanna Nieminen Sanna
Published: September 2024

Organizations depend on the capabilities their members possess to survive and succeed in the highly competitive operating environment. Typically, capability or competence profiles have been created cross-sectionally, serving the current needs of the organization, whilst the Knowledge (KM) and Human Resource Management (HRM) also need to be future-oriented, addressing the emerging needs for new capabilities in an anticipatory manner. The development of capability profiles has moved from I-shaped models stressing the need for deep professional special knowledge to T-shaped models where the emphasis is adding horizontal knowledge capabilities (about business processes and additional knowledge areas) to balance the deep vertical specialization to specific occupational areas. In an ECKM (European Conference on Knowledge Management)  conference paper in 2022, a new model called T2-model was introduced on a conceptual level (Saukkonen & Kreus, 2022). The development step to earlier T-shaped capability models was the addition of a second horizontal layer on top of combinatory capabilities – thus the name of T2. The lower horizontal layer contains business-specific items (like supply chain management, quality, or project management) where advanced knowledge is needed. The higher horizontal layer contains items of phenomena where a basic level of knowledge is needed (e.g., financial literacy, AI principles, sustainability). In the experimental research design, capability profiles were created for selected professional positions.  The capability profiles were created by both business professionals (individuals currently having or managing the profession in question) and higher education professionals (who educate undergraduates and graduates to the industry and function studied). The respondents filled into the visualized T2-model the skills preselected from earlier literature to relevant and were also able to add the skills they felt were missing in the original list of skills for the profession in question. The results give early proof-of-concept of the viability of T2-model as a method of bridging both HRM and KM within organizations as well as University-Industry views on the knowledge items and levels needed for the future. Furthermore, the results give a basis for the knowledge anticipation process. The paper elaborates on a new model for anticipation of knowledge and offers a process that organizations can use in designing their HRM and Knowledge Management. Using T2-model may offer an improved integration to other areas of planning such as technology development and strategic change.
Exploring Knowledge Management Dynamics in International Film Productions: Insights from the Maltese Film Industry
Authors: Zontek Tomasz
Published: September 2024

This paper discusses an empirical analysis of the knowledge management in international film productions. It presents the findings of exploratory data research taking place during the research trip to Malta. The research took place between 2023 and 2024 during two film productions undertaken in this country. The main study aim is to indicate which forms of tacit and explicit knowledge management are used in international film productions. To achieve the aim of this study, several research questions were formulated: What is the nature of knowledge sharing in the Maltese Film Industry? Is it tacit or explicit knowledge that is shared? What is the difference between collaboration and knowledge sharing? What factors influence effective knowledge management within an international film crew, particularly in the context of the Maltese film industry? The study established a research hypothesis: The management skills of the film producer and the heads of departments, as well as efficient management of explicit and tacit knowledge, are essential factors in the success of film production. The multicultural differences of the film crew members are noticeable, but they are not considered as a disadvantage or a barrier. The methodology of this paper is based on qualitative research. A survey was used as the research method and the interview questionnaire was chosen as the research instrument. Interviews were carried out between 2023 and 2024. The study identified best practices for knowledge management during international film productions. Preliminary research results have identified factors influencing the effectiveness of knowledge management, as well as barriers related to the initiatives undertaken. Finally, the results obtained highlight the importance of compromise, mentoring and trust. Film production processes require effective knowledge management and efficient, talented film production managers. These individuals should be familiar with the principles of knowledge management and also be open to the cultural diversity of their employees.

Authors: Jaime Miranda Junior  , José Leomar Todesco  , Denilson Sell  , Caroline de Medeiros  , Lídia Neumann Potrich
Published: September 2024

Knowledge is a fundamental element to enable organizations in anticipating and responding to Operational Safety Events (OSE). The identification and analysis of knowledge flows emerge as strategies to strengthen the potential for organizational resilience, as they qualify the knowäedge necessary for risk mitigation and the strengthening of operational safety. This article presents the results of an empirical research conducted in a sanitation company, aiming to investigate critical knowledge and its flows in complex sociotechnical systems. The research involved interviews with professionals who faced OSEs in their daily activities. OSEs were defined as situations where professionals were able to prevent accidents and/or incidents, successfully dealing with potential threats. To achieve the research objectives, two sequential instruments were used. The first instrument was employed to identify critical knowledge related to OSEs, exploring those mainly related to situational awareness and the repertoire for implementing responses to an OSE. This process revealed a diversity of knowledge, much of which was tacitly present in the minds of professionals and was not formally documented in the company's standard operating procedures. The second instrument was developed to map knowledge flows associated with the identified OSEs. This mapping provided a deeper understanding of how these critical knowledge were shared and used within the organization. The research results evidenced various critical knowledge in the analyzed OSEs, going beyond the information available in tutorials, work plans, or organizations' standard operating procedures. Both instruments used in the interviews were validated and yielded positive results. As a result of this empirical research, the organization now has a valuable understanding of the critical knowledge evidenced, which has the potential to drive organizational learning and strengthen the resilient capabilities of the organization, considering that knowledge resources are a fundamental element for resilience. As a next step, it is aimed to investigate the visual representation of knowledge flows, assess their effectiveness, and provide specific guidelines to enhance knowledge management processes in organizations.
Assessing the Moderating Role of Organizational Culture on the Effect of Knowledge Networks on Firm Innovation in Visegrad Countries: The Perspective of Knowledge Production Function.
Authors: Arthur Emmanuel Ebo , Stejskal Jan
Published: September 2024

Among the elements of Knowledge Production Function (KPF), R&D remains one of the highly studied factors. In an era of interdependence and collaborations, no firm or enterprise can survive the prevailing highly competitive business environment by not networking with firms of similar interest, values, and goals. The unanswered question in prior literature on firm co-operation is what kind of firm co-operation best works? In finding an answer to fill this gap in literature, we examined the impact of R&D co-operation, innovation co-operation (excluding R&D) and co-operation based on other business activities on radical and incremental innovations. We further examined the moderating role of organizational culture on the effect of firm co-operation on innovation. Our study is based on open innovation theory and the KPF. Adopting the 2018 cross-sectional CIS data from the Eurostat database for the four Visegrad countries (Czech Republic, Poland, Hungary, and Slovakia), the OLS regression and Average Marginal Effects models were used for the analysis. We confirmed that when firms co-operate on R&D, there is a positive and significant effect on radical innovation but negative significant effect on incremental innovation. Firm co-operation on innovation activities excluding R&D has positive and significant effect on both radical and incremental innovations. Other business co-operations had positive and significant effect on incremental innovation but not on radical innovation. We further confirmed a positive significant moderating role on the effect of R&D co-operation on radical innovation. We proposed theoretical and practical implications of our study to firm managers, government, and policy formulators.

Business internationalization and globalization naturally led to the need to manage across cultures and develop  new competencies for leaders. One of these competencies is cultural intelligence (CQ) that is actually a meta-competence because it incorporates rational, emotional, spiritual, and social intelligence. Cultural intelligence expresses the capacity of a leader to understand different cultures and the behavioral types generated by them, and to make decisions able to satisfy multicultural requirements, avoiding intercultural conflicts due especially to different cultural and religious values and principles. Different cultures are characterized by different knowledge dynamics which influence the process of decision making and multicultural leadership. The purpose of this paper is to explore the impact of knowledge dynamics on multicultural leadership, in multicultural business environments, and what is the role of cultural intelligence in this process. Based on the critical literature review we identified the main constructs and connections we have to explore through an investigation based on questionnaires and a statistical analysis using PLS-SEM method. The findings confirmed our initial hypotheses.
Knowledge Management and Resilience in SMEs Sector
Authors: Zieba Krzysztof
Published: September 2024

Purpose: The aim of this paper is to investigate the role of resilience in surviving major disruptions, such as pandemic or war. This problem is especially vital for small and medium-sized enterprises (SMEs), as they often lack both resources needed for survival during prolonged economic hardship and knowledge management (KM) practices which are useful for developing the necessary business resilience. Methodology: The paper uses literature review approach to investigate the current knowledge on resilience and its dimensions as well as the links between KM, resilience and operational efficiency. Systems Thinking approach is proposed to be used to show the complexity of mechanisms behind those phenomena and the impact they have on business competitiveness in the SMEs sector. Findings: Because of their nature, SMEs were particularly severely hit by the COVID-19 crisis. SMEs now have to adjust to the new reality of the post-crisis phase by developing their business resilience. KM practices prove to offer high potential in resilience creation and resilience maintenance. Specific features of SMEs, if combined with operational agility and resilience, may allow them to successfully face challenges of their turbulent environment.. Research limitations: This paper is of a preliminary, conceptual nature. Its further development includes investigation of various aspects of KM relevant to strengthening business resilience in SMEs. More data is still needed to develop and test full Systems Thinking model based on the framework proposed here. Practical implications: SMEs owners and managers may benefit from this paper, as they may use it as a guidance in the process of developing business resilience in their organisations. The insights provided in this paper may be useful for decision makers and also for businesses offering knowledge-based services, offering them a deeper understanding of the presented phenomena and relations between them.. Originality/value: The paper is focused on SMEs, which are rarely investigated when it comes resilience creation and benefits it offers. The framework presented here provides important insights, which can be useful to numerous stakeholders.
Creating Expert Knowledge on Aligning Tax Systems With Corporate Business Strategies
Authors: Stepien Marcin
Published: September 2024

The article presents the possibilities of creating expert knowledge on aligning tax systems with corporate business strategies which can help identify new perspectives for the management of companies in the changing legal environment in which they operate. The lack of comprehensive theoretical research on creating expert knowledge regarding the alignment of tax systems with business strategies has led to an attempt at theoretical analysis and empirical research to fill an identified gap on this matter by deepening the understanding of the knowledge creation processes in this area. The considerations made are based on empirical research conducted in 250 companies that use tax systems in their business strategy. The research procedure involved conducting a survey among randomly selected large and medium-sized Polish enterprises, using the CATI Support method, taking into account the Mann-Whitney U test. This article supports the current view that a higher level of alignment between tax systems and business strategy is more likely to affect large companies than medium-sized ones. What is more, the issue of creating expert knowledge on aligning tax systems with corporate business strategies is important and topical, as there are differences in the perception of the alignment between tax systems and corporate business strategy between corporate executives and tax professionals.
Knowledge Creation on Costs in the Context of Economic Environment Changes – Perspective of SMEs
Authors: Biadacz Renata
Published: September 2024

The increasingly challenging geopolitical situation and the growing frequency of various unpredictable crisis threats make the future uncertain and unstable. On the one hand, the sharp rise in raw material prices and labor costs, supply chain issues, pressures to implement sustainable development principles and non-financial reporting, and the transition to a circular economy model is increasing cost awareness and, consequently, the demand for more detailed cost data. On the other hand, the rapid development of technology and digitization, along with the evolution of Industry 5.0, means that business managers increasingly recognize knowledge as an indispensable element of business management. Knowledge management is an excellent tool for streamlining processes, which each company constructs based on its goals, needs, and capabilities, essential for effective planning and proper organizational functioning. Therefore, enterprises are compelled to continuously self-improve and seek new management methods, including cost management. This article raises a research question concerning how cost knowledge is created in SMEs in the context of changes occurring in the economic environment. The article aims to analyze the use of cost knowledge in managerial decision-making in medium-sized enterprises operating in the Polish SME market. The research methods used to achieve this goal include participant observation, critical analysis, and synthesis. The empirical research was conducted in the form of surveys carried out using CATI/CAWI methods among 400 randomly selected medium-sized enterprises operating in Poland, along with personal interviews. The research results suggest managers should focus on acquiring broader knowledge about incurred costs. Many surveyed enterprises still use traditional cost accounting solutions, providing data necessary solely for reporting purposes. The potential and tools offered by cost accounting are used to a limited extent. This indicates a need to continue and expand the discussion on the usefulness of detailed knowledge about incurred and forecasted costs in decision-making processes. The research findings presented in the article are intended for both researchers and practitioners. The article concludes with practical recommendations for enterprises and future research tasks. It is a continuation of the author's research on the role of cost accounting in managing SMEs in Poland.
Assessing the Impact of Science and Technology Parks on Firm Profitability: A Comparative Study of On-Cluster and Off-Cluster Dynamics
Authors: Al-kfairy Mousa
Published: September 2024

Science and Technology Parks (STPs) are pivotal in driving regional development, primarily through fostering innovation and enhancing regional wealth. However, the impact of STPs on regional development remains a contentious topic with inconclusive findings. This study digs into the contribution of STPs to the profitability of firms by conducting a comparative analysis of profitability and salary data between firms located within these parks (on-cluster) and those outside them (off-cluster). The research adopts a two-pronged approach: initially, it examines firm profitability and employee salaries at an aggregate level to understand the overall economic impact of STPs. Following this, it models the various factors that influence firm profitability, offering a nuanced understanding of the dynamics at play. The findings are revealing – being located within an STP (on-cluster) appears to significantly boost a firm's profitability, but only up to a certain size of the cluster. This suggests that the benefits of being in an STP diminish beyond a certain scale. At a more granular, micro level, the study finds that a firm's previous innovation output has a positive impact on its profitability. This underscores the importance of continuous innovation for sustained economic success within these clusters. Conversely, a larger firm size seems to negatively impact profitability within STPs, indicating a potential strategy for growing firms to relocate off-cluster to mitigate this effect. For firms operating outside STPs (off-cluster), the scenario differs. Here, innovation plays a partial role in influencing profitability, and interestingly, the size of the firm does not significantly impact its profitability. This distinction between on- and off-cluster firms highlights the unique economic ecosystems fostered by STPs and their varied effects on firm performance. Overall, this study contributes to the ongoing debate on the role of STPs in regional development, offering new insights into how these entities affect firm profitability and suggesting potential strategies for firms operating within and outside these parks.
