Food Hub or Not Yet? Exploring the Food Hub Milieu in Czechia
Authors: Smutná Zdeňka , Hruška Vladan
Published: July 2024

In global research, food hubs are evaluated as a suitable tool for the development of alternative food networks and the transformation of the agri-food system towards sustainability. However, in Europe, research conclusions in recent years point to a lack of knowledge about operating food hubs. Expanding information about how food hubs work is crucial for improving their operational effectiveness and establishing support from the public sector. Therefore, this exploratory research aims to discover examples of food hubs in Czechia where the term "food hub" is not used and no appropriate equivalent has been developed. This leads to the task of determining the criteria under which it is possible to define existing entities as food hubs. Using several examples supported by qualitative research, the article opens a discussion about the acceptability of the hybridization of alternative food networks. Our findings contribute to the debate about the potential of food hubs to develop local and regional food markets, especially in the context of post-socialist countries, where the conditions are different from the Western states.

Authors: Mata Fernando , Cano-Díaz Concha , Jesus Meirielly
Published: July 2024

The European Common Agricultural Policy (CAP) has evolved over the years, and climate change mitigation and sustainability were recently added as objectives to the policy. This sustainability policy includes subsidies for farmers. The success of EU policies relies on positive public perception. This study aimed to investigate Europeans' perception of EU sustainability subsidies. This analysis was complemented by evaluating citizens’ attitudes towards agriculture and climate change and socio-economic variables. Overall, EU citizens support CAP and sustainability practices. Our findings reveal that EU citizens strongly in favour of this support tend to be older, more educated, politically left-wing, from higher social classes, residing in smaller communities, and optimistic about the EU's future. Additionally, these citizens hold strong environmental concerns and support innovative practices to benefit sustainable agriculture.

Due to its many engineering applications, low manufacturing costs, and environmental friendliness, 3D printing is considered one of the most promising manufacturing technologies. The quality of printed parts will inevitably be affected by the controllable variables used in the 3D printing process. The present study aims to investigate how different printing process parameters affect the bending strength of PLA prints. The ASTM D790 standard was used to fabricate the samples in this work, while the Taguchi principle was used to design the experiments. The following values were chosen: shell width (0.8, 1.2, 1.6, and 2 mm), layer thickness (0.15, 0.2, 0.25, and 0.3 mm), and infill density (40%, 60%, 80%, and 100%). The results showed that fill density is the most effective variable for improving bending strength. Measurements of infill density (100%), layer thickness (0.15 mm), and shell width (2 mm) gave the best results, which were calculated to be 83.1479 MPa in bending test. The mathematical model in this study was developed using linear regression analysis, and the residuals confirmed that the model fit the data well, with a maximum error of 6.1%.

The ongoing involvement of homeless former prisoners in crime raises questions about involvement factors. Failure to reintegrate into society frequently results in homeless former prisoners becoming re-involved in crime. The situation is particularly worrying when the recurring criminal involvement involves other overlapping factors, which should be identified for a sound understanding of this homeless group. In this research, 30 homeless former prisoners, nine Malaysian government agency officers, and nine volunteers were interviewed in this study. Several sub-themes, namely peer influence, self-confidence conferred by drugs, and drug addiction, were derived from interviews with homeless former prisoners. The officers’ interviews revealed the sub-themes of mental disorders, addiction problems, survival, friends’ influence, environmental influence, personal choice, and unrepentant. The volunteers’ interviews revealed the sub-themes of friends’ influence, unemployment, drug activity-filled environments, and drugs as a necessity. The findings provide an insight into the influence of drugs, which were among the leading contributing factors to the involvement of homeless former prisoners in crime. This comprehensive study involved three population groups and filled knowledge gaps on homeless former prisoners. Efforts to reduce recidivism require a diverse approach, which includes policies, agencies, and action plans.

This cross-sectional design study examined rural-urban fertility differences in The Gambia. We used the 2019-20 Gambia Demographic and Health Survey data. A multi-stage sampling technique was used to select women of reproductive age (8,747 urban & 3,119 rural). Data were analyzed using descriptive statistics, Kitagawa’s Decomposition technique, and the negative binomial (NB) model, α = .05. The mean Children Ever Born (CEB) was higher in the rural (3.25 ± 3.02) than in the urban (2.19 ± 2.45) areas. In the urban and rural areas, 82.8% and 95.1% of women aged 45–49 years who had had three children progressed to fourth birth, respectively. The parity progression rate (λ) was lower in the urban (-0.0647) than in the rural (-0.051). The difference between the standardized fertility rates in rural and urban areas was 83.2 in The Gambia, and the effect of the age composition attributable to this difference was 8.11%. The fertility incidence rate ratio (IRR) was 44% (IRR = 1.440, 95% CI [1.371, 1.513], p < .001) higher in the rural than the urban areas. A similar pattern of rural-urban differences in fertility was observed in the full model. Childbearing progression was higher in rural areas than urban areas and rural-urban differences exist in fertility determinants in The Gambia. Thus, rural-urban-specific fertility reduction programs may address the observed fertility differences in the rural and urban areas in The Gambia.
Cybersecurity and the Evolution of the information space: a phenomenological analysis of the relationship with the metaverse and the digital world
Authors: Kochetkova Natal'ya Pavlovna
Published: July 2024

The subject of the study is cybersecurity, within the framework of the modern changing conditions of the information space, which is filled with such phenomena as the metaverse and the digital world. These systems create new threats and problems in the processing, transmission, preservation and confidentiality of data. Assuming that the intersection of cybersecurity, digital transformation (including the metaverse and the digital world) and phenomenological analysis is an important area of research, the paper examines aspects of building cybersecurity in the country. The merger itself is seen as a centrifugal current that cannot be stopped, but must be regulated, which suggests that the transformation of approaches to cybersecurity plays a crucial role in developing effective strategies to overcome the problems that arise in a rapidly changing digital landscape.  The research methods are based on data collection, analysis and synthesis, which revealed key problems. The key method is a phenomenological analysis of the ongoing changes in the information sphere associated with the spread of the phenomena of the metaverse and the digital world, which made it possible to reflect the problems of information processing and insecurity from malicious attacks and propose a new approach to the formation of a cybersecurity system. The scientific novelty of the article lies in an integrated approach to studying the relationship of cybersecurity, the evolution of the information space and such new concepts, like the metaverse and the digital world. The transition to the latter is the next stage in the development of the information space, which can be traced in the gradual expansion of ecosystems and personal information platforms. All this suggests the need to expand the system of providing personal information, as well as data that gets into unsecured information networks. At the same time, domestic cybersecurity systems are being criticized, which indicates the need to find new solutions. One of these options may be a phenomenological approach to the study of data. The study shows how the use of phenomenological research methods allows us to take a fresh look at the capabilities of domestic developers to strengthen cybersecurity measures and adapt them to rapidly changing digital landscapes.

Published: July 2024

Introduction

Hypertension is an important factor driving mortality among dialysis patients. Angiotensin-II receptor blocker (ARB) has been effective similarly to angiotensin-converting enzymes (ACEs) but with a low incidence of side effects.

Methodology

The meta-analysis included all published studies that investigated the effect of ARB on the hypertension in adult dialysis patients (≥18 years). Data extraction was guided by a predetermined checklist. Data sources of the retrieved studies were PubMed, MEDLINE, ScienceDirect, SCOPUS, Cochrane, Web of knowledge, and Google Scholar were systematically searched until February 2023. Using the RevMan 5 software, the mean difference for systolic and diastolic BP (SBP and DBP) and the risk ratio (RR) of the adverse events (AEs) were pooled from the selected studies. The random-effects model was used to compare the difference in the pre-and post-dialysis of the SBP and DBP. Data analyses were performed from December 2022 to February 2023. The primary outcome was the reduction in SBP and DBP in dialysis hypertensive patients who were on anti-hypertensive agents, and the secondary outcome was assessment of AE associated with the drug after dialysis (PROSPERO Registration: CRD42022355369).

Results

The initial search yielded 1,679 records, of which 84 studies underwent full-text evaluation, which identified 13 studies and 1,462 patients. The pooled standard MD for losartan with other anti-hypertensive agents, where the pre-dialysis SBP was 0.17 (95% confidence interval [CI]: −0.21–0.55) and the post-dialysis was 0.35 (95% CI: −0.17–1.02); yet, both are statistically non-significant, implies that there was no difference between Losartan and ARB drugs regarding the effect on the SBP. Diastolic BP for predialysis was −0.01 (95% CI: −0.65–0.63) and post-dialysis was 0.03 (95% CI: −0.24−0.30) and statistically non-significant. AEs by the ARB agents were lower compared to other anti-antihypertensive agents (relative risk [RR]: 1.01; 95% CI: 0.59–1.75) and statistically non-significant.

Conclusion

This systematic review and meta-analysis of RCT demonstrated that ARB and other anti-hypertensive medications had similar impacts on the treatment of hypertension.

Published: July 2024

Background

Increased caregiver burden undermines caregivers’ mental and physical health and is an under recognized but critical aspect for the success of continuous ambulatory peritoneal dialysis (CAPD). This study was undertaken to quantify and identify the factors determining CAPD caregiver burden.

Materials and Methods

A cross-sectional study was conducted among 51 caregivers of CAPD patients visiting the centers from July to August 2023. Caregiver burden score was determined using “Zarit Burden Interview” by interview method.

Results

The mean age of caregivers was 42.8 ± 10.83 years with 52.9% females. The mean Zarit burden score of the caregivers was 29.18 ± 11.81. Younger caregivers experienced significantly higher burden (r = −0.34, P = 0.013). Lesser educated caregivers were perceiving a higher burden. Lower socioeconomic strata people had significantly higher burden (P < 0.001) and especially so when there was a loss in income attributed to caregiving. Patients who were covered by state insurance experienced a notably lower caregiver burden (19.2 ± 6.1) when compared to those who were self-financed (32.4 ± 11.08) or had company insurance (37.2 ± 13.6). Gender, religion, marital status, and type of family had no bearing on the caregiver burden.

Conclusion

Age, loss of income, education, and socioeconomic status are important determinants of caregiver burden. State sponsored program lowers caregiver burden significantly. A CAPD program should address these factors to mitigate caregiver burden.
Variación temporal en estimaciones de abundancia de Panopea abbreviata en diferentes sustratos: Monitoreo mediante vídeo remoto de bajo costo en el Golfo San Matías, Atlántico Sur

Published: July 2024

Las almejas del género Panopea pertenecen a la familia Hiatellidae, se distribuyen en los mares templados y son recursos pesqueros en la mayoría de las regiones donde habitan. Estos bivalvos suelen agruparse en sustratos arenosos o fangosos, presentando variaciones temporales en su abundancia, o más precisamente, en su detectabilidad. Tradicionalmente, los bancos de estos organismos son monitoreados mediante buceo autónomo, lo que plantea limitaciones de seguridad en profundidad y de tiempo de buceo. En este estudio se evaluó el desempeño del método de vídeo remoto de bajo costo denominado ‘Toki’ para evaluar y monitorear Panopea abbreviata en el Golfo San Matías. Las observaciones de abundancia fueron analizadas mediante modelos aditivos generalizados mixtos, usando temperatura, profundidad, fecha de muestreo y calidad de imagen como covariables. Observamos un patrón diferencial de abundancia de P. abbreviata, con picos en los meses de octubre y mayo, en contraste con lo reportado para otras especies del mismo género. La variación de abundancia fue más alta en comparación con informes previos para la región. En concordancia con esos informes, P. abbreviata presentó una abundancia significativamente más alta en sustratos de arena. El método ‘Toki’ resultó eficaz, cubriendo áreas extensas de forma sencilla y en poco tiempo. Entre las principales ventajas de la técnica están la accesibilidad a mayores profundidades y menores limitaciones de tiempo de muestreo que en el buceo; sobre todo, a profundidades >25 m. Asimismo, con esta técnica se logra un registro permanente que se puede usar luego con nuevos objetivos. Es necesario destacar que todo el procedimiento se realizó desde una embarcación pequeña y de forma manual, lo cual implicó costos relativamente bajos y facilitó el trabajo. Sin embargo, el buceo puede ser una técnica complementaria a tareas intensivas en áreas pequeñas.

Authors: Ayala Florencia E. , Avalos Adan A. , Cajade Rodrigo
Published: July 2024

La introducción de especies exóticas constituye una de las principales amenazas para la biodiversidad a nivel mundial. Spathodea campanulata es una especie arbórea cultivada como ornamental, cuyo néctar tóxico presenta propiedades con actividad insecticida, en especial contra abejas. En la Argentina se desconocen sus efectos sobre la entomofauna. Por lo tanto, este estudio explora los efectos de mortalidad causados por S. campanulata sobre la entomofauna nativa en un área verde de la ciudad de Corrientes. A partir del estudio de tres árboles se analizó el porcentaje de flores con especímenes de entomofauna muertos en su interior y se determinó la abundancia de los taxones representados. Se calcularon índices de diversidad, riqueza de especies, completitud del inventario y curva de rango abundancia. Los resultados indican que la abeja nativa Scaptotrigona jujuyensis presentó la mayor mortalidad, con un total de 46 ejemplares de un total de 151, entre los que se hallaron representantes de los órdenes Himenoptera, Diptera, Coleoptera, Hemiptera y Araneae. Este estudio exploratorio advierte que S. campanulata es una amenaza potencial para la entomofauna nativa en áreas urbanas.

Published: July 2024

Desde el siglo pasado, los ecosistemas acuáticos de Tierra del Fuego se encuentran bajo el impacto de la introducción de especies exóticas. Entre ellas se destacan el castor norteamericano —Castor canadensis— y los salmónidos por su dispersión y abundancia. Este estudio se enmarca en el proyecto Fortalecimiento de la Gobernanza para la Protección de la Biodiversidad Mediante la Formulación e Implementación de la Estrategia Nacional Sobre Especies Exóticas Invasoras, para la erradicación de C. canadensis de la Isla Grande de Tierra del Fuego (IGTdF). El objetivo del trabajo fue evaluar el efecto de remover castoreras sobre diferentes aspectos de la ictiofauna de la IGTdF. Se realizaron muestreos ictiológicos antes y después de la remoción de las castoreras en seis sitios distribuidos a lo largo de la isla. Se capturaron tres especies de salmónidos (Salmo trutta, Oncorhynchus mykiss y Salvelinus fontinalis) y se observó un aumento promedio de 43% en su abundancia, cambios en su dieta y diferencias en su densidad energética (mayor o menor dependiendo de la especie) luego de remover las castoreras. No se registraron especies nativas de peces ni antes ni después de la remoción. Los resultados sugieren que las castoreras tienen un impacto positivo en las poblaciones de salmónidos.

Published: July 2024

This study investigates the prevalence and geographic distribution of co-infection involving Pasteurella multocida (P.multocida) and Chicken anemia virus (CAV) in poultry populations across various regions of India. From August 2019 to May 2020, organ samples from poultry flocks suspected of Fowl cholera (FC) and CAV were collected. The study included ten samples representing instances of co-infection obtained from six Indian States: Andhra Pradesh, Haryana, Karnataka, Gujarat, Maharashtra and Telangana. The study used polymerase chain reaction (PCR) to determine the co-infections of P.multocida and CAV, mainly focusing on P.multocida-induced immunosuppression leading to subsequent CAV infection. Among the co-infection cases, two samples exhibited concurrent infections, one with Avian Leukosis Virus (ALV) and another with Mycoplasma gallisepticum (MG), along with P.multocida and CAV. Understanding the immunosuppressive mechanism is crucial for effective control measures and mitigation of economic losses in the poultry industry.

Authors: Gahlawat S.K. , Saharan P. , Duhan J.S.
Published: July 2024

Loop-mediated isothermal amplification method was developed for the detection of Aeromonas hydrophila. Four primers were designed against the hemolysin gene of A. hydrophila and conditions were standardized for the amplification of DNA. This method amplified the A. hydrophila from nutrient broth, water and tissue samples. When compared, LAMP method was found to be more sensitive than PCR. The LAMP method was also highly specific and did not amplify DNA purified from other bacterial species. LAMP amplification was observed from the stored master-mix up to six weeks and thus, it can be successfully used as a kit for detection of A. hydrophila.

Published: July 2024

Skin cancer occurs when skin cells undergo uncontrolled growth. One in three cancer patients worldwide is affected by skin cancer which has a significant impact. Chemotherapeutic medications work to kill cancer cells, but they can cause long-term morbidities that degrade one's quality of life and are only effective when cancer is in early stages. As a result, experts began to consider using traditional medication to treat the illness effectively and with fewer side effects. Naringin is a naturally occurring flavanone that is prominent and has a variety of pharmacological actions. It is particularly available in citrus fruits. Finding antiproliferative drugs that reduce skin cancer is an extremely important activity. Using Epidermoid carcinoma cells (A431), we evaluated the impact of naringin in exhibiting anticancer activities. The MTT evaluation of Naringin in A431 cells revealed the IC50 concentration 72μg/ml, it is similarly effective to the Imiquimod's IC50 value 52μg/ml. Additionally, flow cytometric analysis was performed to detect the molecular mechanism underlying the Naringin's antitumor actions. Naringin caused apoptosis as induced by early and late apoptotic cells as compared to the control, further decreased reactive oxygen species ROS and decreased mitochondrial membrane potential in A431 cells. The outcome demonstrates naringin's anticancer ability against a skin cancer cell line. The reported effects on ROS production, apoptosis and decreased viability of A431 cells may have cumulative or synergistic effects. In future, the in vivo and clinical studies in naringin may overlay a way to produce antitumor drug for the treatment of skin cancer.

Published: July 2024

The fish processing sector presents environmental challenges due to the generation of by-products like viscera, scales, fins, frames and gills. This study focuses on sustainably utilizing scales from Catla catla, a by-product of this industry, by converting them into nutrient-rich media for microbial culture via acid hydrolysis. The aim is to formulate to develop and to validate a comprehensive microbial nutrient medium sourced from freshwater fish scales. The process involves acid hydrolysis of Catla catla scales at 37°C for 15-17 hours, utilizing 10% hydrochloric acid, followed by heating at 100°C for 2-3 hours and subsequent neutralization with 1N sodium hydroxide. The properties of the resulting hydrolysate powder were analyzed for compositional amounts of total nitrogen, ash, fat and moisture content, solubility and ability to support the growth and multiplication of bacterial strains Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). The findings revealed that the microbial medium derived from Catla catla scales exhibited a chemical composition of 4.5% moisture, 16.33% total nitrogen, 0.31% fat and 6.5% ash, with a pH of 7.1 and a solubility of 99.25%. In bacterial growth tests, the medium produced from Catla catla scales demonstrated a faster growth rate compared to commercial media. These results suggest that Catla catla scales, as a by-product, hold promise as a raw material for producing a complete nutrient microbial medium, serving as an efficient growth medium for bacteria. This approach contributes significantly to both environmental sustainability and resource optimization within the fish processing industry.

Bacillus subtilis group produces a variety of secondary metabolites in which siderophores are lower molecular weight iron chelating compounds produced to overcome iron deficient environments and aid the delivery of iron inside the bacterial cell for numerous metabolic activities The present study aims to isolate and evaluate Bacillus species from fermented soybean food and soil samples for the detection of siderophores. A total of 20 samples including soil (11) and fermented soybean food (9) were processed by serial dilution and the Bacillus species isolated. Morphological testing, biochemical testing and 16S rRNA gene sequencing were performed to confirm the phenotype and genotype of the isolates. Two media such as Luria Bertani (LB) and iron-deficient succinate media (IDSM), were utilized for siderophores production by qualitative and quantitative measures using the Chrome Azurol Sulfonate (CAS) assay. Using phenotypic and genotypic characterization techniques, 26 Bacillus species were isolated from 20 samples. Based on phenotypic and genotypic methods, among 20 samples, 26 Bacillus isolates were identified. The supernatant of all the isolates in LB broth was positive whereas IDSM was negative qualitatively. However, in quantitative analysis, both LB and IDSM demonstrated the yield of siderophores. Thus, the study concludes that Bacillus species producing siderophores can be promising candidates with wide applications in pharmaceutical and environmental studies.
A mini review of Tilapia Lake Virus (TiLV): Disease pathogenesis and host immune response against virus
Authors: Saranya S.R. , Sudhakaran R.
Published: July 2024

The use of tilapia for farming is increasing every year to meet the worldwide demand for protein sources. Unexpectedly, high mortality rates of tilapia, known as tilapia lake virus (TiLV), have been observed in various countries, including India. TiLV is a pathogenic virus with a trilaminar capsid that is composed of a negative-sense icosahedral RNA virus. Infected tilapia exhibit noticeable signs and symptoms, indicating the presence of the disease. Understanding TiLV is crucial for effective preventing of its spread in the tilapia farming industry. Interferons can hinder viral particles by inhibiting viral replication in the host. These bony fish species require type I and III interferons to protect against the virus. Type I interferons act against all nucleated cells, while type III interferons specifically target dendritic and epithelial cells. Interferon-stimulating gene (ISG) expression, induced by signaling molecules, blocks the virus from spreading to other cells. In vertebrates, the type I IFN-inducible gene product 'Mx' has demonstrated high resistance to orthomyxovirus infection. Recent findings suggest that TiLV lacks HA ligands for binding to the Sia receptor. Protein kinase (PKR), an integral component of the innate immune response, is considered the first-line defense molecule against viral infection in fish. When the viral pathogen enters the host cell, PKR is activated by dsRNA and phosphorylates the translation initiation factor eIF2α, triggering an innate immune response activated by type I interferon. The host immune response to pathogens is also regulated by cytokines which effectively induce inflammation during TiLV infection. Recent research has shown that intraperitoneally injected zebrafish are susceptible to TiLV infection. Therefore, zebrafish were chosen as a model organism for studying the immune response against TiLV. Zebrafish possess a well-developed immune system that allows for the study of both innate and humoral immunity, providing insights into the antiviral activity of both the host and the pathogen. There is limited understanding of the structure of the virus and minimal information on the immunopathogenesis of TiLV. Therefore, a comprehensive understanding of disease strategies is necessary to develop solution to this epidemic.
Plant growth and adaptive responses to Cd stress under effects of nitrogen nutrient: A review
Authors: Bui Thi Tuyet Xuan
Published: July 2024

Mining activities cause heavy metals (HMs) contamination in arable soil, plants absorb heavy metals and may be indirect causes of adverse impacts on human health. The mobility of HMs in soils at high levels might be accumulated or fixed in the parts of plant (phytostabilization), may easily take up by plants to provoke adverse impact directly on living organisms. The aim of this work was to assess the effectiveness of nitrogen (N) nutrient and its combination with other micro-elements to improve growth and yield of plants and to enhance plants adaptive responses to Cd stress. Our results indicated that the inhibitory effect of Cd toxicity on plant growth traits and photosynthesis was reduced by N application. Fertilizer N might have been involved in the regulation of hormone signaling pathways and stomata opening in response to Cd stress. Fertilizer N can increase tolerance resulting to better growth of plants under Cd stress through stimulation of antioxidant enzyme activities and inducing the expression of related coding genes. Overall, the findings indicated that an adequate of N nutrition was essential for the adaptive responses and increased plants tolerance to Cd stress.

Загрязнение малых рек в результате сельскохозяйственной деятельности является серьёзной проблемой. Во время дождей и паводков в малые реки из поверхностных слоёв почв поступают загрязняющие вещества. В данной работе представлены результаты изучения гидрохимических показателяй малой реки и распространения тяжелых металлов в компонентах речной экосистемы (воде, рыбе). Для вод малой реки Манга летом характерно высокое насыщение кислородом и высокое содержание органического вещества, что свидетельствует об эвтрофировании экосистемы реки. Полученные результаты изучения гидрохимических показателей малой реки Манга позволяют выявить закономерности взаимодействия природных и антропогенных компонентов и оценить возможность сохранения биоразнообразия речной экосистемы.

Энторопийные принципы дают базисную основу формирования функциональных связей между многими величинами химической кинетики. Равновесная сумма энтропийных составляющих универсальной газовой постоянной равная R/2, имеет прямую математическую связь с тангенсом геодезического угла. Аналогичное соотношение этого параметра получено по графикам Аррениуса - зависимости коэффициента скорости реакции от температуры. При движении в одном формате двух энтропийных составляющих равновесная сумма их энергий равна половине первоначальной величины энергии. Природное моделирование энтропийных принципов проявляется и в других закономерностях в химической кинетике и в физике, например, в энергии активации диффузионных процессов и в уравнении кинетической энергии. Практическое применение энтропийной методологии в научных исследованиях позволяет найти рациональное решение поставленных задач.

В статье проанализированы промежуточные итоги админи- стративной реформы в Республике Мордовия. Переформатирование систе- мы государственного управления было направлено на развитие экономики, снижение административных барьеров, повышение качества предоставля- емых гражданам услуг, модернизацию организационной структуры мини- стерств и ведомств, сокращение бюджетных расходов, обеспечение финан- сового контроля и внедрение информационных технологий в деятельность органов государственной власти и органов местного самоуправления Респу- блики Мордовия. Выделены основные этапы и ключевые мероприятия про- веденных преобразований. Реализованные процедуры не привели к росту социально-экономического развития, продемонстрировав недостаточную эффективность работы системы государственного управления. При этом были достигнуты положительные результаты в области регламентации функ- ций органов власти и предоставления услуг. Снижению экономических по- казателей способствовали организационные, информационные и кадровые причины.
