Kreowanie polityki informacyjnej władz samorządowych na tle zmieniającego się rynku mediów. Studium przypadku polskich miast
Authors: Kowalik Krzysztof
Published: June 2024

Celem artykułu jest przedstawienie działań w obszarze polityki informacyjnej największych polskich jednostek samorządu miejskiego, które mogły być wywołane zmianami własnościowymi na rynku mediów lokalnych (zakup przez Orlen tytułów Grupy Polska Press) oraz obawami przedstawicieli miast o przekaz mediów publicznych dotyczący funkcjonowania samorządu terytorialnego. Metoda badań obejmuje kwerendę dokumentów zamieszczanych w Biuletynie Informacji Publicznej i informacji publikowanych przez media oraz obserwację oficjalnych miejskich serwisów online i profili w mediach społecznościowych. Wybrano największe polskie gminy (powyżej 300 tys. mieszkańców – dziewięć ośrodków), których prezydentki/prezydenci w wyborach samorządowych 2018 r. nie kandydowali z list Zjednoczonej Prawicy. Analizą objęto okres od publikacji informacji o kupnie przez Orlen Grupy Polska Press (przełom lat 2020/2021) do końca roku 2022. Wyniki i wnioski: sześć z dziewięciu największych polskich jednostek samorządu miejskiego podjęło działania zwiększające liczbę kanałów dystrybucji własnych treści. Stworzyły one tytuły prasowe i zintensyfikowały przekaz online (portale oraz profile w mediach społecznościowych). Oryginalność i wartość poznawcza: badanie wypełnia lukę poznawczą, gdyż do tej pory nie prowadzono analizy działań samorządów miejskich mogących wskazywać na korelację między tworzeniem własnych kanałów dystrybucji treści w przekazie tradycyjnym i cyfrowym a zmianami własnościowymi na rynku mediów lokalnych oraz opiniami niektórych władz samorządowych dotyczącymi narracji mediów publicznych.
Impact of Public Debt Refinancing Techniques on Managing Public Budgeting in Iraq: An Analytical Study
Authors: Abdul Razaq Abdul Wahaab* Noor , Hasan Ali Azhar
Published: July 2024

The use of public debt by the state as a primary financial instrument is an essential strategy for directing economic activity, ensuring economic stability, and fostering economic growth. Despite this, as the levels of public debt continue to climb, governments are increasingly resorting to debt refinancing methods that are focused on either replacing or rescheduling current debt or converting to a new kind of creditor via investment and securitization investment vehicles to relieve the burden of their debt. Utilization of these instruments is essential for effective management of the overall budget. The discovery that debt scheduling and the debt sustainability index impact the accomplishment of fiscal surpluses and maximizing public revenues informed the study's results in Iraq, which inspired the conclusion that debt refinancing methods and general budget advice are connected. In order to reduce public debt with the possibility of eliminating it, to take advantage of the time it gives to initiate a strategy for investing in projects that contribute to increasing public revenues through which that debt can be repaid, to achieve sustainable economic growth, and to reduce the budgetary deficit, the author of the study recommended that the mechanism of scheduling public debt in its entirety and not just a part of its structure be implemented. Implementing the technique of scheduling public debt in its totality rather than simply a portion of its structure may help achieve these aims.

Feasibility of Establishing and Re-operation of Industrial Projects in Iraq Through import-substitution strategy
Authors: Fadhel Kazem* Durgham , Mahmoud Rashid Alani Thaer
Published: July 2024

The research idea originated from the significance of the industrial sector and its pivotal role in inducing structural and systemic changes at the national economic level. Given the numerous challenges the industrial sector faces in Iraq, many industrial projects have partially or entirely ceased operations. In contrast, state-owned industrial companies have become a burden on the government. Import substitution through manufacturing is considered one of the leading strategies and most vital industrial approaches that have historically catalyzed industrial growth and structural transformations in the economy. This has been evident in the development of countries that initially relied on primitive economic models centred around simple agriculture and the export of raw materials and transitioned into diversified economies with a significant industrial component, producing numerous high-quality and technologically advanced products. Based on this, the study aims to assess the compatibility of this strategy with the current Iraqi economic landscape. It seeks to shed light on inactive industrial projects and companies, exploring the feasibility of reactivating them or establishing new industrial ventures. Priority will be given to projects aligned with its objectives and goals. Additionally, the study aims to provide a forward-looking perspective on the state of the industry in Iraq's prospects, diagnose existing problems, and attempt to find solutions and remedies that can contribute to establishing a reliable industrial sector.

Published: July 2024

The paper features an examination of the link between the behavior of the Money supply and Bank deposit in both an autoregressive distributed lag ARDL, plus a nonlinear autoregressive distributed lag NARDL framework. The regression relationship between any two nonstationary time series suffer from the problem of superior regression and the results may be incorrect and unreliable, and to overcome this problem the aim of this paper was find a balanced relationship in the long - run between the variables of Money supply and Bank deposits using the method of cointegration by focusing on the behavior of the residuals of the cointegration model based on monthly data for a time series for the period (2010-2015). The time series stationary test was done by conducting the Unit Root Test based on the Philips-Perron test to find out the stationary of the variables and then detect the existence of the cointegration using the bounds testing, the tests showed the nonstationary of the time series at level I(0) and their become stationary after taking the first differences I(1). Bounds test showed the existence of cointegration .The Error correction model for the ARDL model was the best, despite the convergence of most of the test results for the two models, but the ARDL model was  the more accurate with the speed of adjustment in the short -run to return to long-run equilibrium, as it reached (37%) and a period of two months for the ARDL model, while the percentage for the NARDL model was equal to (28%) and a period of time of approximately three and a half months.

Published: July 2024

Local savings are an essential source for financing sustainable development. The research is based on careful analysis due to the importance of local savings in the Iraqi economy for the period (2003-2022) to provide the necessary local financing necessary for development investments in infrastructure and investments that enhance economic growth and productivity, generate job opportunities, and achieve The goals and indicators of sustainable development and the extent of the efficiency of those local savings and their impact on the average per capita share of GDP. The research aims to examine the effect of the efficiency of local savings on the level of per capita income of GDP. Moreover, it analyzes the potential impact on income distribution in the local community. The research adopts a multi-faceted approach that uses quantitative data to analyze the statistical relationships between the level of efficiency of local savings and the average per capita income from the gross domestic product, as local savings constitute an essential part of the local and national economy. The research starts from the hypothesis that the efficiency of local savings is represented by both the Local resource gap and the financing gap, which impacts the average per capita output and is linked to a causal relationship with the efficiency of local savings. The importance of this significant impact on the average per capita income, as local savings rates, the efficiency of these savings, and the local savings and financing gaps in Iraq were analyzed by cointegration analysis. The most important results showed that increasing the efficiency of local saving is linked to an increase in local investments, thus improving the level of per capita income and that there is a direct relationship between the Local resource gap and the average per capita share of GDP and an inverse relationship between the financing gap and the average per capita share of GDP.

Authors: Zakrzewska-Bielawska Agnieszka , Flaszewska Sylwia , Sowa Mateusz
Published: July 2024

Idea zrównoważonego rozwoju jest istotna dla zachowania równowagi pomiędzy ekonomicznymi, społecznymi i środowiskowymi aspektami rozwoju przedsiębiorstw i innych organizacji. Jednym z jej fundamentów jest współpraca przynosząca nie tylko wartość ekonomiczną, ale przede wszystkim wartość społeczną. W artykule poszukiwano odpowiedzi, w jakim stopniu współpraca uczelni z biznesem koncentruje się na czystej komercjalizacji, przynoszącej zyski finansowe, a w jakim uwzględnia wpływ społeczny. Wyniki badań przeprowadzone metodą wywiadu w 13 jednostkach naukowo-badawczych ze świata wskazują, że uczelnie europejskie podejmują przede wszystkim działania waloryzacyjne, podobnie jak uczelnie kanadyjskie, dla których ważnym działaniem w tym procesie jest mobilizacja wiedzy. Z kolei w uczelni amerykańskiej pierwszoplanową rolę nadal odgrywa komercjalizacja wiedzy.

Authors: Szczech-Pietkiewicz Ewelina , Czerniak Adam
Published: July 2024

Artykuł jest wynikiem badania wykonanego na próbie 400 polskich przedsiębiorstw zajmujących się produkcją towarów i usług. Celem badania była analiza potencjału, jaki modele biznesowe obiegu zamkniętego tworzą dla rozwoju przedsiębiorstw, zwłaszcza w kontekście wyzwań rozwoju zrównoważonego. W artykule dokonano oceny praktyk gospodarki obiegu zamkniętego wśród polskich przedsiębiorstw, wskazując na różnice w opiniach na temat ich wpływu na działalność gospodarczą. Dostrzegając korzyści, takie jak redukcja kosztów i zwiększona konkurencyjność, dwie trzecie zbadanych firm nie inwestuje w rozwiązania cyrkularne, głównie ze względu na postrzegane przeszkody inwestycyjne. Ponadto prawie połowa z nich nie posiada celów strategicznych w zakresie gospodarki odpadami, co wskazuje na potrzebę większej świadomości i strategicznej integracji zasad obiegu zamkniętego. W badaniu zauważono również ogólny brak uznania modeli gospodarki obiegu zamkniętego jako przewagi konkurencyjnej, a dodatkowo niewiele przedsiębiorstw wskazano jako wzorce do naśladowania. Sugeruje to rozbieżność między uznaniem korzyści wynikających z gospodarki obiegu zamkniętego a faktycznym wdrożeniem, co podkreśla potencjał zachęt finansowych sprzyjających przyjęciu tej gospodarki.

Authors: Laktionov O , Laktionova I
Published: June 2024

Purpose. Improving the optimization method for predicting the efficiency of a robotic platform (using the gradient boosting method as an example). Methodology. The process of refining the optimization method for predicting efficiency has been investigated using robotic platforms as complex systems comprising hardware components, data exchange technology, security systems, and navigation, along with user interaction methods. The optimization method relies on a linear equation, whose mathematical model, through the triple interaction of factors, consolidates assessments of subsystem elements into an efficiency index for the robotic platform. The outcomes of the proposed optimization algorithm result in regression models from machine learning. These acquired models are employed for predicting the efficiency of a specific configuration of a robotic platform designed to perform particular practical tasks. Findings. The optimization method for predicting the efficiency of a robotic platform has been enhanced by utilizing evaluations of the robotic platform efficiency index as input data. In comparison to existing methods, the proposed index demonstrates minimal values of root mean square deviation at 0.1794, 0.14 and 0.1245, respectively. This particular characteristic has enabled the development of a more accurate optimization method for predicting the efficiency of robotic platforms. This assertion is supported both theoretically and empirically through criteria such as Root Mean Square Error, Mean Absolute Error, and Maximum Absolute Error on experimental datasets. Originality. The optimization method for predicting the efficiency of a robotic platform differs from existing approaches through its model-building process, which consists of two iterations and incorporates different sets of input evaluations. The first iteration involves primary and index-based evaluations of the robotic platform’s efficiency, while the second iteration incorporates primary, index-based evaluations, and predicted index-based evaluations. Practical value. Selection of the optimal configuration of a robotic platform for addressing tasks in the energy sector. Cost reduction through a finely tuned combination of robotic platforms. The proposed solutions will contribute to the Development Concept of Artificial Intelligence in Ukraine.

Aspects of reproductive biology are important information in efforts to monitoring fish resources. Aspects of reproductive biology of K. hexapterus to be observed include: sex ratio, Gonadal Maturity Rate, and Gonadal Maturity Index. Fish sampling was carried out in October – December 2021 using splint net fishing gear. Determination of observation stations by purposive sampling method, where based on the location of fishermen install splint nets. The results obtained the sex ratio of male and female K. hexapterus (1: 0.34).  Male of the Gonadal maturity Rate only at levels I-II while females are level I-IV. It can be concluded based on the results of the study, that there is too much difference in the ratio between male and female fish caught, so that Gonadal maturity Rate of male fish is not obtained that is ready to spawn. However, in female fish there are already those who reach Gonadal maturity Rate IV phase, this means they are ready to spawn. Male of the Gonad Maturity Index (0.12 - 0.43%) and female (0.11 - 2.98%). Conditions like these can make it difficult for female fish to find males who are also gonadally mature and equally ready to spawn.
