The Effect of Fiscal Decentralization on The Human Development Index and Its Components: A Panel Data Study
Authors: TÜMAY Muhammed
Published: October 2021

Most countries worldwide in recent decades, particularly developing and transition countries, have implemented decentralization in their governance structures. The main purpose of decentralization is the idea that local government can deliver local needs and preferences to their communities more accurately. However, some researchers argue that decentralization has its limitations and point out an optimal fiscal decentralization size. This paper investigates the effect of fiscal decentralization on the human development index and its components by using panel data between the period 2000 to 2010 from 49 countries. Using robust OLS and Fixed Effect methods, results suggest that the revenue measure of fiscal decentralization has a significant and positive effect on the human development index. Furthermore, results show that this effect is non-linear may diminish once the degree of fiscal decentralization crosses a threshold.

Background: COVID-19 caused the worst international public health crisis, accompanied by major global economic downturns, mass-scale job losses, which impacted on the psychosocial wellbeing of the worldwide population. This study examined factors associated with psychosocial distress, fear of COVID-19 and coping strategies amongst the general population in Saudi Arabia.Methods: A cross-sectional study was conducted using an anonymous online questionnaire. Multivariate logistic regressions were used; Adjusted Odds Ratio (AOR) with 95% Confidence Intervals (CIs) was reported.Results: Among 803 participants, 70 %(n=556), were females and the median age was 27 years; 35% (n=278), were frontline or essential service workers; 24% (n=195), reported comorbid conditions including mental health illness. Factors associated with moderate to high levels of psychological distress were: youth (18 - 29 years) (AOR 3.35, 95% CIs 2.06 - 5.44), females (2.59, 1.60 - 4.19), non-Saudi nationals (2.17, 1.11 - 4.26), change in employment (2.9, 1.73 - 4.87), negative financial impact (2.14, 1.29-3.56), having comorbidities (2.67, 1.47 - 4.87), and current smoking (2.87, 1.55 - 5.33). Being ex-smokers (3.72, 1.14 - 12.14) and change in employment (3.42, 1.91 - 6.11) were associated with higher levels of fear of COVID-19. People whose financial situation was impacted and who had contact with known/suspected cases (1.63, 1.12-2.38) had low medium to high resilient coping.Conclusions: People in Saudi Arabia were at a higher risk of psychosocial distress and fear along with low resilience during the COVID-19 pandemic, warranting urgent attention from healthcare providers and policymakers, to provide specific mental health support strategies for their wellbeing currently and to avoid a post-pandemic mental health crisis.

Authors: Bhatia Meenakshi , Kumar Ashwani , Verma Vikas , Yadav Snehlata , DEVI SUNITA
Published: October 2021

The present piece of research work is framed as improving the solubility of ketoprofen by forming co-crystal using fumaric acid as a coformer. Co-crystal of ketoprofen and fumaric acid were prepared by simple solvent assisted grinding. The independent variables i.e. drug and coformer were mixed in 1:1 molar ratio and dependent variables were assumed to be solubility and % drug release. Differential scanning calorimetry, fourier transform infrared spectroscopy, X-ray diffraction, nuclear magnetic resonance and scanning electron microscopy techniques were used to characterize the preparation of optimized batch of co-crystal and further, evaluated for in-vitro and in-vivo anti-inflammatory and analgesic activities. Based on results of solubility and dissolution rate studies the drug showed 4-5 fold improvement in both the properties on co-crystallisation. The values of Gibbs free energy are negative at all levels of carrier demonstrating spontaneity of drug solubilization process. The IC50 value of optimized batch of co-crystal formulation and pure drug was observed as 327.33 µg/ml and 556.11 µg/ml, respectively, demonstrating that co-crystal formulation possesses more percentage protection against protein denaturation than the drug ketoprofen. In-vivo (anti-inflammatory and analgesic) activities revealed that optimized batch of co-crystal formulation delivered a rapid pharmacological response in wistar rats and albino mice when compared with standard drug.
TNFα-Mediated Necroptosis in BBB Endothelia as a Potential Mechanism of Increased Seizure Susceptibility in Mice Following Systemic Inflammation
Authors: Huang Wan-Yu , Lai Yen-Ling , Liu Ko-Hung , Lin Shankung , Chen Hsuan-Ying , Liang Chih-Hung , Wu Hung-Ming , Hsu Kuei-Sen
Published: October 2021

BackgroundSystemic inflammation is a potent contributor to increased seizure susceptibility. However, less is known about the effects of systemic inflammation on blood-brain barrier (BBB) that affect neuron excitability. Necroptosis and inflammation are intimately associated in various neurological diseases. We hypothesized that necroptosis is involved in the mechanism underlying sepsis-associated neuronal excitability in BBB components.MethodsSystemic inflammation was induced by LPS. Seizure susceptibility of mice was measured by kainic acid intraperitoneal injection. Pharmacological inhibitors (C87 and GSK872) were used to block signaling of TNFα receptors and necroptosis. To identify the features of sepsis-associated response in the BBB and CNS, brain tissues of mice were obtained for assays of the necroptosis-related protein expression, and immunofluorescence staining for morphological changes of endothelia and glia. Microdialysis assay was also used to evaluate the changes of extracellular potassium and glutamate levels in brain.ResultsSignificant findings including induced increased seizure susceptibility and BBB endothelia necroptosis and leakage, Kir4.1 dysfunction, and microglia activation were observed in mice following LPS injection. Inhibition of TNFa receptor inhibitor C87 significantly attenuated increased kainic acid-induced seizure susceptibility and endothelia necroptosis and microglia activation, and restored kir4.1 protein expression, compared with those in controls. GSK872 (a RIP3 inhibitor) treatment, like C87, had consistent effects on these changes following LPS.ConclusionsOur results showed that TNFα-mediated necroptosis in BBB endothelia damage contributes to the development of increased seizure susceptibility in mice after systemic inflammation. Pharmacologic inhibition targeting this necroptosis pathway may provide a promising therapeutic approach to reduce sepsis-associated BBB dysfunction, astrocyte ion channel dysfunction, and subsequent neuronal excitability.
Survival rate, adaptation ability and carbon production and sequestration of 21 green oak (Quercusrotundifolia Lam.) provenances at Mounts of Saida (western Algeria)
Authors: Khatir Hadj , Yahia Nasrallah
Published: October 2021

Due to recent global changes, a substantial degradation of natural ecosystems in North Africa and difficulties of species regeneration have been observed. A comparison of 21 green oak (Quercus rotundifolia Lam.) provenances in different bioclimatic zones was carried out at two ecologically different stations in western Algeria. The main objectives of the study were to (a) assess the survival rate and development in the natural environment of young individuals who derive from it, (b) gain an understanding of the level of morphological variability and (c) explore the possibilities of adapting the different provenances of green oak in the west Algerian ecological regions. The field trial was established in 2008 at two sites. The average survival rate ten years after the establishment of the field trial was 38.50%, with a total height average of 122.95 cm, a dry epigeous biomass production of 0.0630 t/ha and a sequestered amount of atmospheric carbon (CO2) of 0.0859 t/ha. The green oak provenance (origin) of Zaccar from the Tellian Atlas group is distinguished by a higher survival rate and dryer epigeous than other origins. The variability of large regions of the country means that there are four areas in which varieties can show superiority in survival and biomass: those representing the Northern part of the Saharan Atlas, those of the high inner plains, those of the southern facade of the Tellian Atlas and finally those of the Saharan Atlas.

Published: October 2021

Background: Acute respiratory distress syndrome (ARDS), which is caused by severe immune cell response and associated alveolar inflammation, is also a critical complication in hospitalized patients with COVID-19. Triptolide is a powerful anti-inflammatory and immunosuppressive drug and is proved to help relieve the inflammation of ARDS. However, its anti-inflammatory effect on COVID-19 patients with ARDS complications remains uncertain. Methods: In this study, human normal lung epithelial cells (BEAS-2B), the pseudovirus system of syndrome coronavirus 2(SARS-CoV-2) and lipopolysaccharide (LPS) were used to construct as severe COVID-19-pseudovirus cell model to explore the effects of triptolide on cell viability, secretion of inflammatory cytokines, and gene expression. Results: The results showed that triptolide increased cell viability, decreased the secretion levels of cytokines IL-6, TNF-a, and increased the expression of IL-10. Furthermore, transcriptome analysis in this cell models showed that the Differentially expressed genes (DEGs) were related to plasma membrane integrity, metabolic activity and mitochondrial function, and were associated with TNF, FOXO, mTOR and MAPK signaling pathways. Conclusion: Take into consideration previous studies on the functions of triptolide in BEAS-2B cells, the current study indicated that triptolide can play a critical role in protecting against inflammatory damage and maintaining the normal physiological function of BEAS-2B cells in response to pseudovirus and LPS infection.
Advised or Paid Way to get it right. The contribution of fact-checking tips and monetary incentives to spotting scientific disinformation
Authors: Panizza Folco , Ronzani Piero , Mattavelli Simone , Morisseau Tiffany , Martini Carlo , Motterlini Matteo
Published: October 2021

Disinformation about science can impose enormous economic and public health burdens. Several types of interventions have been proposed to prevent the proliferation of false information online, where most of the spreading takes place. A recently proposed strategy to help online users recognise false content is to follow the techniques of professional fact checkers, such as looking for information on other websites (lateral reading) and looking beyond the first results suggested by search engines (click restraint). In two preregistered online experiments (N = 5387), we simulated a social-media environment and set-out two interventions, one in the form of a pop-up meant to advise participants to follow such techniques, the other based on monetary incentive. In Experiment 1, we compared these interventions to a control condition. In Experiment 2 another condition was added to test the joint impact of the pop-up and the monetary incentive. We measured participants' ability to identify whether presented information was scientifically valid or invalid. Results revealed that while monetary incentives were overall more effective in increasing accuracy, the pop-up contributed when the post originated from an unknown source (and participants could rely less on prior information). Additional analysis on participants’ search style based on both self-report responses and objectively measured behaviour revealed that the pop-up increased the use of fact-checking strategies, and that these in turn increased accuracy. Study 2 also clarified that the pop-up and the incentive did not interfere with each other, but rather acted complementarily, suggesting that attention and literacy interventions can be designed in synergy.

Published: October 2021

Large cardamom (Amommum subulatum Roxb.) a high valued spice crop grown in Sikkim Himalaya is now facing a devastating leaf blight disease that has brought down the yield drastically. Present study was focused on identification of this major fungal pathogen based on the morphological and molecular characterization. During this study infected leaves of large cardamom with blighted appearance were collected from all the four districts of Sikkim. The pathogen was isolated using Potato Dextrose Agar (PDA) medium, incubated at 25°C. The mycelium was septate, hyaline, and 2-4 µm wide. The conidiospores were cylindrical with both ends rounded, sometimes oblong. Length and breadth were 11-12 µm and 3-4 µm, respectively. On the basis colony morphology, growth and microscopic observations, out of the total 48 samples studied Colletotrichum sp. was identified from 14 samples. Based on phylogenetic analysis of the ITS4, ITS5 and ApMAT genes and phenotypic characters (colony morphology, microscopic features) the isolate (No. LC05) isolated from the sample collected from the village Assam Linzey, East Sikkim showed 100% homology with Colletotrichum fructicola from NCBI database. The pathogenicity of C. fructicola was also confirmed during the study. The fungal culture has been deposited at the NFCCI-ARI, Pune with an accession number NFCCI 4542 and the sequences have been deposited in NCBI GenBank with accession number (ITS) MN710587, (ApMAT) MW348934 respectively. To the best of our knowledge this is the first report of C. fructicola causing blight disease of large cardamom. Also the finding is very important to improve the disease control strategies of this high valued cash crop.
Diagnostic Yield of Chilaiditi’s Sign in Advanced-Phase Late-Onset Pompe Disease
Authors: Takahashi Junichiro , Mori-Yoshimura Madoka , Ariga Hajime , Sato Noriko , Nishino Ichizo , Takahashi Yuji
Published: October 2021

Purpose: Chilaiditi’s sign (CS), hepatodiaphragmatic interposition of the intestine, was caused by morphological abnormalities such as diaphragmatic atrophy, intestinal dilation, and liver atrophy. The sign is potentially important due to associations with clinically recurrent abdominal pain or even colonic volvulus. In general, neuromuscular disease (NMD) could have the high prevalence of CS because of widened hepatodiaphragmatic space, following diaphragmatic atrophy. Particularly, in late-onset Pompe disease (LOPD), glycogen accumulation in smooth muscle of intestine could lead to the abnormal dilation of intestine. Though the prevalence of CS in LOPD could be high because of developing two main factors of CS, no studies have evaluated the prevalence of CS in LOPD. Our aim was to investigate the prevalence of CS in LOPD, and to identify the risk factors of CS in LOPD patients. Methods: Medical records of genetically confirmed patients of Pompe disease at the National Center Hospital, National Center of Neurology and Psychiatry were retrospectively reviewed. We evaluated CS using chest X-ray (CXR) and abdominal CT and assessed the prevalence of CS in LOPD patients. We also divided the patients into two groups, CS and non-CS group, and evaluated the factor associated with CS compared to clinical variables between groups. Results: Three of seven (43%) were detected in CS. CS group (P5-7) and non-CS group (P1-4) were obtained. In comparison of clinical variables, the severity of atrophy in right diaphragms was significantly higher in CS than non-CS groups (p =0.029). Also, the frequency of abnormal position of right diaphragm and liver, and abnormally dilated bowel was seen in all of CS patients, but none of non-CS patient (p = 0.029, each). Conclusion: In LOPD patients, the prevalence of CS was much higher of 43%, compared to healthy groups, or even in similarly respiratory muscle impaired neuromuscular diseases such as Duchenne muscular dystrophy (DMD) or Myotonic dystrophy type 1 (DM1). The anatomically abnormal position of diaphragm and liver, atrophy and fat infiltration of diaphragms, and abnormally dilated bowel were significantly associated with CS in LOPD. Since CS can cause intestinal symptoms or even contribute to sudden-death of intestinal volvulus, we should pay more attention to CXR or abdominal CT as follow up in LOPD patients.

Оптимизированная система мониторинга сибирского шелкопряда Dendrolimus sibiricus Tchetverikov (Lepidoptera: Lasiocampidae) была разработана в ходе выполнения международного проекта «Лесные ресурсы и технологии» (ФОРЕСТ), профинансированного Агентством США по международному развития (USAID) в 2001-2005 гг. Она включает последовательные стадии лесопатологического районирования субъектов федерации, отдельных лесхозов, организации феромонного мониторинга разреженных популяций шелкопряда и лишь при фиксации ловушками подъема численности (выше 100 бабочек/ловушку/сезон) - перехода к учету гусениц. В ходе проекта впервые разработана технология феромонного мониторинга вредителя (синтезирован аналог феромона, созданы диспенсер, ловушки и фиксирующие инсектицидные пластинки, рекомендована методика учетов и алгоритм принятия решения). Проект профинансировал создание трехтомного справочника «Болезни и вредители в лесах России», впоследствии изданного Агентством лесного хозяйства Российской Федерации. Опробованная и внедренная в ходе проекта на территории Томской, Иркутской, Сахалинской областей, Красноярского, Хабаровского, Приморского краев и Республики Бурятия система мониторинга служит ярким примером плодотворной кооперации ученых Российской академии наук и лесных вузов с практиками лесного хозяйства.

The optimized monitoring system of the Siberian moth Dendrolimus sibiricus Tchetverikov (Lepidoptera: Lasiocampidae) was developed during the implementation of the Forest Resources and Technologies (FOREST) international project funded by the United States Agency for International Development (USAID) in 2001-2005. It includes successive stages of forest pathology zoning of the subjects of the Russian Federation, individual forestry enterprises, organization of pheromone monitoring of sparse Siberian moth populations and, only when the population growth is recorded by the means of traps (above 100 male moths / trap / season) - transition to caterpillar sampling. In the course of the project, the technology for pheromone monitoring of the pest was developed for the first time (a pheromone analogue was synthesized, a dispenser, trap and fixing insecticidal strip were created, a methodology of accounting and a decision-making algorithm was recommended). The project financed the creation of a three-volume handbook "Diseases and Pests in Russian Forests", subsequently published by the Forestry Agency of Russian Federation. The monitoring system tested and implemented in the course of the project in the Tomsk, Irkutsk, and Sakhalin Districts, Krasnoyarsk, Khabarovsk, Primorskiy krays and the Republic of Buryatia serves as a vivid example of fruitful cooperation between scientists of the Russian Academy of Sciences and forestry universities with forestry practitioners.
THE THEME OF THE GERMAN SUBMARINES’ACTIVITIES COVERED IN THE PRESS PROPAGANDA ON THE OCCUPIED TERRITORIES OF UKRAINE (BASED ON THE MATERIALS OF “SUMY HERALD” IN 1941-1943)
Authors: Nesterenko V.A.
Published: October 2021

The materials of the newspaper “Sumy Herald” published during the period of the German occupation in the city of Sumy and devoted to the German submarines’ activities are analyzed in the article. The objective of the publication is to highlight the usage of this theme by the German propaganda to influence the Ukrainian population through the local press. The author has come to the conclusion that newspapers were the most widespread and effective form of propaganda at that time on the occupied territories of the USSR and Ukraine. In comparison to the radio and cinema they were able to cover the considerable part of the rural and urban population. The reports concerning the conduct of military operations were produced centrally and did not take into consideration the specific nature of perceiving this sort of information by the local population. They reports were overloaded with digital, geographic data and specific terms. Only in the second half of 1942 the articles, maps and charts meant to explain certain issues of the undersea war were produced. The greatest attention to the German submarines’ activities was paid by the propaganda in the period from February to September 1942. This is related to the successful actions of the German troops at the Eastern coast of the North Africa. The information concerning this theme was generally published on the first page. It was printed in the headings or subheadings, the bold font was used in the text of the article. Sometimes some illustrations in the form of photos and cartoons were used. The latter were not very common in the newspapers of that period. The information about the undersea war was provided quite promptly and in general was accurate. Except the loses of Britain and its allies in separate military operations the general data concerning the tonnage of sunk ships was published. The information about the German submarines loses was not given in contrast to the loses of the planes, for example. The reports references to the names of the submarines’ captains without providing any information about their personalities had no “personification” effect. Perhaps, it might be compensated by other sources of propaganda, for example by “Die Deutsche Wochenschau” series in the cinemas. But the latter covered a considerably lesser audience in comparison to the newspapers.

Mother wavelet selection using signal energy for cracks detection in the rotation shafts
Authors: Codruta Pricop
Published: October 2021

The mother wavelet greatly influences the wavelet analysis of a non-stationary and nonlinear recorded signal. Choosing mother wavelet must be done to determine cracks in rotating shafts so as to take into account the nature and type of information signals to be extracted from the signal. The difficulty in optimum selection of the mother wavelet is determined by their complex properties that determine different selection criteria. In the paper, several families of functions (Haar, Daubechies, Symlets, Coiflet, BiorSplines) were used for analysis and the proposed selection criterion is the energy dissipated on the frequency bands. Signal recordings were made on a stand to determine the presence of cracks in rotating shafts and their classification. For discrete decomposition of recorded signals (DWT) and the calculation of energy dissipated on the frequency bands the Matlab wavelet instrument was used.
Reducing GHG Emissions at Military Vessels
Authors: Doru Coșofreț
Published: October 2021

The shipping industry is responsible for 3% of global greenhouse gas (GHG) emissions, emissions mainly resulting from the combustion of fuels in naval energy aggregates. The current requirements for a 50% reduction in GHG emissions by 2050 represent a challenge for maritime transport, as there is no effective solution to reduce this emissions from ships. Thus, the current problem is represented by insufficient methods to reduce CO2 emissions on board ships, in particular for ships which are in service for more than 10 years, which are the most affected by these environmental requirements, since their design did not take into account the reduction of ecological parameters. In this context, even if military vessels are not subject to IMO GHG emission reduction requirements, they must be aligned with global emissions reduction efforts. This article presents actually operational and technological solutions to reduce CO2 emissions that can be deployed on board military vessels, until other technical solutions or power supply solutions for non-polluting renewable energy aggregates are identified.
Methodology for identification, analysis and evaluation of risks in the maritime industry. Study case: Container Maritime Transport
Authors: Nicolae FLORIN
Published: October 2021

The paper proposes a methodology for identifying, analyzing, and evaluating risks for the maritime industry, presented systematically. In the research, the methodology we applied to container ship, for a generic model of the fully cellular containership type and three modes of operation. The conceptual framework of the research was organized into three stages, which are detailed in the paper. Risk analysis and evaluation took into account the provisions of the IMO (Revised Guidelines for Formal Safety Assessment - FSA for use in the IMO rule- making process). The major / priority risk factors were grouped into 12 risk scenarios, and the consequences of their materialization were related to 4 types of risk (the risk for human life, risk for the environment, risk for cargo, risk for the ship. The authors consider that the proposed research can be used by adapting it to identify, analyze, and evaluate the risks for the other types of ships.

Authors: Alexandru Curcă
Published: October 2021

In the context of network evolution, concepts like Software Defined Networking (SDN) and Network Functions Virtualisation (NFV) appeared on the market. Network virtualization permits the implementation of routers, switches and load balancers in software and separation of control plane and data plane brings easier configuration, implementation and scalability. The monolithic design of traditional network devices can be changed by implementing new algorithms which will improve the overall system performance. An example is our Software Load Balancer with a Genetic Algorithm. The code written in Python is functional through the POX Controller and the advantages of evolutionary algorithms make this implementation an innovative solution for dynamically modified topologies.
Operational anomalies identification of the turbo blowers using statistical analysis of the experimental data
Authors: Elena Răducan
Published: October 2021

In this paper is presented a method for anomalies identification that may occur in equipments operation because of the large variations, above the limits, of the process parameters. The method is developed by using statistical approach and visualization tools of the processed data. The scientific visual method is generally used to control, monitor and improve processes by removing special cause variation. The statistical process control (SPC) has an advantage over other methods, because it can be applied to any process with its emphasis on early detection and prevention of problems. The objective for this paper is to present the technique used to control and monitor the Turbo Blower equipment, from steel industry. The purpose of statistical analysis is to ensure that all processes function as accurately as possible within the tolerance limits.
Comparative analysis of two maritime routes in part of North America in the context of global warming, melting ice caps and opening of new passages for navigation
Authors: Dinu Atodiresei
Published: October 2021

The subject of this paper is to analyze comparative two maritime routes planned different for a ship that carry cargo from the United Kingdom to the Norton Sound, (63o 48’N / 161o21’W). The route are analyzed separately as a result of the evolution of the thermal regime, the ice in the last ten years in the area of North America and the impact of ice caps, from the perspective of total distance and opportunity of navigation. Take into consideration all three possible routes on this date, only the north-west route was included in this comparative analysis. The results presents a difference of 6070 Nm between the classic route (using Panama Channel) and the route through north-west passage, in safety condition.
Logistics processes and quality framework in port operation
Authors: Bucur MARIUS
Published: October 2021

The port operation services have developed a specific framework of business processes of which model is commonly defined by the peculiar logistic activities provided for goods handling in stevedoring operations or for storage, stowage, unitization, or processing operations with added value alongside the flow of the supply chain. In the last decades the port services have been enlarged and diversified not only on extensive basis but intensively also, having on its ground new methods of business processes modelling in completion to the updated equipment and technologies. In this context, the port development is calling for a higher level of social and environmental responsibility, the quality management standards becoming very important for a successful business on sustainable development perspective. Due to its excessive diversification, the quality management framework has been considerable diversified, making difficult the recognition of all the required procedures and standards, to be acquired and implemented on different areas of port logistic functions and processes. The authors’ main purpose for this paperwork was to identify and to depict the most relevant processes, actively pursued in the stevedoring operations, as to further draw a synoptic panel of applied quality management standards, in order to serve the sustainable efforts in harmonizing the business practices in compliance with the social, environmental and public responsibility imperatives.
Modelling the grain terminal cargo supply process using the road transportation
Authors: Marius Bucur
Published: October 2021

The largest share of operations in a specialized port terminal consists in grain supply processes usually delivered by motor trucks, on traditional road transportation means. In this respect, any process improvement could add value with a high impact against the terminal productivity. The traditional grain port operation technologies can no longer be used because the maritime business in particular requires new operating rules embedded by the integrated logistics variables, that ensure a shorter delivering time and an enhanced safety framework for cargo operation. Under these circumstances, the processes’ automation using modern technologies of supply, internal transportation, storage and forwarding of cargo flow, permanently monitored with an accurate control of operations, have determined the modern silo functional model. Moreover, the specific operations in the terminal are not only performed by automated processes, but there are many interventions and activities dependent on the human factor. This paper comes with an element of novelty, depicting the most relevant subprocesses carried out in the process of receiving grains in the terminal, in case of road shipment by truck. The authors have developed a model on this scenario, under a logical and generally valid flow sequences, that can be used by both those who want to update the terminal effectiveness and those who forth seek to benefit from a modern terminal functionality, valuing the processes and subprocesses improvement potential, in order to increase the quality of actions taken and the labour productivity, by eliminating port operation congestion and ultimately increasing the operational profit.

Considerations regarding the sources of corruption
Authors: Violeta-Ioana Nagat
Published: October 2021

Corruption is a threat to democracy, the rule of law, social equity and justice, erodes the principles of efficient administration, undermines the market economy and endangers the stability of state institutions. Therefore, the fight against this phenomenon must be carried out by the legally authorized authorities, with the support of civil society, without any obstruction, so that no one is perceived as being above the law. In this context, the prevention of acts and facts of corruption, by monitoring conflicts of interests and incompatibilities, as well as by controlling the assets acquired illegally, must be the support of any strategy in this field. Adopting adequate measures to prevent the "corruption" phenomenon requires knowing its real size, its complexity, the trigger mechanisms and the consequences produced. The complexity and the continued diversification of the forms of manifestation of this phenomenon, together with the tendencies of globalization, require the design and elaboration of appropriate strategies, which scientifically and systematically approach the criminogenic sources and the effects of the crime and offer the effective tools for social prevention and control. The phenomenon of "corruption" is generated by ideologies, norms, individuals and groups with antisocial behavior, institutions and organizations.
