Impact of Marketing Tactics on the Performance of Oyster Mushroom Cultivation among Small-Scale Farmers: A Study in Mumias Division, Mumias Sub-County, Kenya
Authors:   Faculty of Business and Management Kampala international University-Western Campus, Uganda, Nyakundi Andrew, O.
Published: November 2023

Mushrooms, as macro-fungi capable of thriving above and below ground, are a rich source of nutrients and can be successfully cultivated within well-ventilated structures using organic substrates. China is the global leader in Oyster mushroom production, accounting for 80% of the total output, with Africa contributing relatively little. In Kenya, two mushroom species are grown: Button and Oyster, with a combined annual production of 500 tons and an additional 150 tons imported. Button mushrooms dominate production at 95%, while Oyster mushrooms represent only 5% of the total output. Among farmers, the majority (80%) focus on cultivating Oyster mushrooms, while the remaining 20% prefer Button mushrooms. Despite the availability of suitable substrates and the preference of growers, the performance of Oyster mushroom cultivation has remained suboptimal. Consequently, the impact of marketing strategies on Oyster mushroom performance has remained uncertain. This study aimed to investigate the influence of marketing strategies employed by farmers. The research was grounded in Innovation theory and guided by a conceptual framework. A descriptive research design was adopted, with a study population of 300 individuals, and a random sample of 30 respondents was selected using cluster random sampling. Data were collected through questionnaires and interview guides and analyzed using SPSS. The results revealed that 56.7% of the farmers sold mushrooms in rural open markets, while 43.3% supplied their produce to hotels and restaurants. Furthermore, 53.3% of farmers engaged in personal selling, whereas 46.7% relied on vendors for distribution. In terms of sales, 76.7% marketed mushrooms through their respective groups, while 6.7% used retailers. Regarding packaging, 96.7% of farmers utilized polythene bags, with a small proportion (3.3%) opting for bottles. On pricing, 70% sold 50gm packages for Ksh 100, while the remaining 30% offered 1kg packages priced at Kshs 2000. A significant majority (83.3%) of farmers sold processed mushrooms, while 16.7% focused on fresh mushrooms. In conclusion, the study found that existing marketing strategies had a limited impact on the performance of Oyster mushroom cultivation. The study recommends intensive training, the development of incentive schemes, the construction of cold storage facilities, and the formation of mushroom cooperatives to enhance the industry's performance. The findings of this research have implications for policymakers, mushroom growers, scholars, and researchers in the field. Keywords: Mushroom, Oyster, production, marketing strategy

Designing for Liberation: A Case Study in Antiracism Instructional Design
Authors: Ikeda Ryan , Nham Kai , Armstrong Laura , Diec Fiona , Kim Nicole , Parada Douglas , Sanchez Diana , Zhen Kelly , Robinson Victoria
Published: November 2023

While grappling with the COVID-19 pandemic and the ongoing racialized, anti-Black violence, uprisings around the nation have launched anti-racism into popular consciousness and discourse. In higher education, many statements of solidarity with Black lives have been made with few structural changes offered or enacted. This essay positions instructional design as a material act that extends the organizing logic of education to learners and students (Harney and Moten, 2013) and offers anti-racism as a multimodal framework for instructional design centered upon dismantling the organizing logics of white supremacy and building liberatory possibilities, especially for Black, Indigenous, People of Color (BIPOC). The essay directs these questions and concerns to a case study, the Creative Discovery Fellows program (CDF) at U.C. Berkeley.
Equity Unbound as Critical Intercultural Praxis
Authors: Zamora Mia , Bali Maha , Mehran Parisa , Cronin Catherine
Published: November 2023

This article traces the emergence of Equity Unbound, originally founded as “equity-focused,
open, connected, intercultural learning curriculum” (Equity Unbound, n.d.) and designed with a
critical curriculum approach. We outline how our design and praxis centers on social justice and
how our activities and purpose have continued to evolve to respond, with care, to the needs of
our networks. We then offer a critical autoethnographic account from an educator who started on
the margins of Equity Unbound and later became a key co-facilitator.
Designing a Virtual Learning Environment for Critical Media Literacy Education
Authors: Söken Ali , Nygreen Kysa
Published: November 2023

In this reflective practitioner essay, we describe our redesign of a large undergraduate course, “Education and Film” (EdFilm), which teaches Critical Media Literacy (CML) to 181 students at a large state university. Using Practitioner Inquiry methods, we discuss the significance of the broader social context in shaping our design, show how we used Universal Design for Learning (UDL) to inform five design choices, and share outcomes from the course. Our findings indicate our course redesign increased flexibility and accessibility without sacrificing student learning outcomes. Reflecting on these findings, we argue for a redesign process that puts student learning goals at the center, considers the impacts of social context (especially with regard to social inequalities), and applies UDL to maximize accessibility and social justice.
With Our Community, for Our Community: Expanding Possibilities for Engaging in STEM
Authors: Nation Jasmine , Sen Francesca , Duncan Joi , Sañosa David , Durán Richard
Published: November 2023

We examine shifting perceptions of STEM for Latinx teens involved in a “Community STEM” environment. This design shows promise in broadening the definition of science and leveraging expertise of STEM-underrepresented youth. However, these programs are still not typical and merit further investigation. Therefore, we examined a Community STEM project where Latinx teens addressed local noise pollution. Teens documented sound levels, created graphs and maps, presented to stakeholders, and built acoustic panels. Researchers employed an ethnographic perspective, identifying science-relevant roles and artifacts. Artifacts became focal points, promoting reflection on noise pollution, potential solutions, and roles in the project and community.
How Instructional Designers Approach Conflict with Faculty
Authors: Mueller Chad , Richardson Jennifer , Watson Sunnie , Watson William
Published: November 2023

Using a multiple case study approach, we interviewed 14 instructional designers working at different universities to explore the approaches and strategies they utilized when experiencing conflict with faculty. While past practitioner-based research has identified strategies instructional designers employ to cultivate effective and productive collaborations with faculty, there are no similar publications examining how practitioners in the field handle conflict with faculty during these collaborations. Based on an analysis of the interview data, we uncovered conflict prevention and management strategies used by instructional designers that synchronizes with three phases of a typical faculty collaboration timelines: (1) at the outset of the collaboration (2) during the collaboration; and (3) post collaboration. Results suggest an interconnectedness across the approaches and strategies. This article concludes with a discussion of our findings including future research and implications.
Considering What Faculty Value When Working with Instructional Designers and Instructional Design Teams
Authors: McDonald Jason , Elsayed-Ali Salma , Bowman Kayla , Rogers Amy
Published: November 2023

The purpose of this research was to study what university faculty valued when working with instructional designers and instructional design teams to develop educational simulations. We did this through a case study of three faculty, where we analyzed what they discussed among themselves or communicated to other team members about what mattered to them about their team relationships or the design processes they employed. We structured our case report around three thematic issues that expressed how our participants depicted good relationships and processes. Our report concludes with a discussion of how instructional designers could use our findings in their practice.
Mediating Artifacts
Authors: Moore Stephanie , Tillberg-Webb Heather
Published: November 2023

While we usually discuss multimedia in the context of frameworks such as Mayer’s theory of multimedia learning, our frameworks for multimedia lack a contextualized approach that recognize other dimensions and impacts of the work we do with mediating artifacts. Educational technology at its core centers around the introduction of mediating artifacts into learning and performance environments. Shifting from an emphasis on media (i.e., things) to mediating allows us to differently frame the work we do and the artifacts we introduce into systems, emphasizing not merely the nature of the things but the impacts of them as well.
Conclusion: A Trauma-Informed Instructional Design
Authors: Bogard Treavor , Carr-Chellman Alison
Published: November 2023

Most instructional design practices are founded on relatively systematic, linear models which tend toward pseudoscientific determination of learning goals, measurable objectives and outcomes. However, this special issue’s contributors reveal design approaches that transcend lock-step models. Collectively, their accounts center practices that are humanity-centered, co-constructed, and adaptive to learner needs. In this vein, a move toward a trauma-informed practice of instructional design will focus on the importance of collaboration, communication, and care. Care involves listening to learner preferences, recognizing learning needs, anticipating potential barriers to learning, embedding targeted tools and supports, and remaining adaptive to the population served.
How the War in Gaza May Upend Israel’s Constitutional Limbo
Authors: Kozlov Noam
Published: November 2023

The war in Gaza serves, this blog post argues, as the final nail in the coffin of Netanyahu's judicial overhaul. The Israeli political climate, relentless opposition and the political fallout after Hamas' surprise attack on Israel and the current war thwarted the judicial overhaul. However, populism is far from overcome. Therefore, the current failed judicial overhaul remains a warning sign for the democracy-seeking public in Israel and should raise demand for constitutional entrenchment of the democratic values of the Israeli state. As the judicial overhaul of 2023 has shown us – democracy is not safe if it hangs by the thread of a simple majority in parliament.

Seroprevalence of cytomegalovirus antibodies positivity among voluntary blood donors in the Delta State University Teaching Hospital (DELSUTH), Oghara, and its environs in Delta State - Nigeria
Authors: Yusuf EO  , Nwagu M
Published: November 2023

Background: Cytomegalovirus (CMV) is widely distributed globally and it is found in different geographical and socioeconomic groups. It can be transmitted from person to person via blood transfusion or tissue/organ transplantation and if the receipt is immune-compromised, then a severe infection and mortality can occur.

Study Objective: The purpose of this study is to determine the seroprevalence and risk factors for Human Cytomegalovirus (HCMV) among blood donors in DELSUTH and its environs.

Materials and Methods: This is a randomized cross-sectional study of voluntary blood donors for the purpose of replenishing stock in the blood bank system of the Delta State University Teaching Hospital, Oghara-Delta State, Nigeria and also from outreach blood donation centres around DELSUTH during blood donation campaigns. Five millilitres of venous blood was taken from each voluntary blood donor and assayed for CMV IgG and IgM using enzyme linked immunosorbent assay.

Results: A total of 185 voluntary donors were recruited for this study comprising of 162 males and 23 females. The age of the donors ranges from 23 to 62years. Human CMV IgG seroprevalence rate for males is 93% and for the females 91%. Therefore the overall CMV IgG seroprevalence rate is 92%. The CMV IgM seroprevalence rate is zero percent. There is no significant difference between the seroprevalence rates in respect of their gender, age, occupation, level of education and previous history of blood transfusion. (p>0.5)

Conclusion: The rate of seroprevalence of CMV is high among the studied population and this call for screening of voluntary-donor's blood before transfusion especially to those that are immunocompromised.
Review and epidemiological description of rape cases among female adolescents seen at secondary healthcare facility in Abak, south-south Nigeria
Authors: Iyanam VE  , Udoh B  , Akinbami OS
Published: November 2023

BACKGROUND: The rising incidence of rape pandemic among female adolescents is a worrisome phenomenon. This is made worse by the negative culture of underreporting of this devastating crime due to stigmatization of its victims resulting in under prosecution, especially in developing countries.

OBJECTIVE: We undertook a review and epidemiological description of rape survivors among adolescent girls seen at a secondary missionary health care facility in Abak, Akwa Ibom State, South-South Nigeria.

METHODS: This was a retrospective review and description of all rape survivors among female adolescents seen at Mercy Hospital, Abak, Akwa Ibom State between January 2016 and December 2017. The case records of all the adolescent females who presented at the facility during the period of the study were sorted out from the health information unit of the facility. Cases of rape among them were identified. Data from the rape survivors case notes including socio-demographic characteristics, location and nature of the attack, time interval between attack  and presentation, notification of police, profile of the perpetrators and treatment response offered to the victims were extracted,  collated and entered into a spread sheet for analysis.

RESULTS:Out of 278 adolescent girls who presented at the facility during the period of the study due to one morbidity or the other, 15(5.40%) were cases of rape survivors. The mean age of the rape victims was 14.17 + 2.35 years. Results obtained show that most of the victims (66.67%) were younger adolescents (10-15years), 80% had formal education while 73.33% of them lived with their parents. Also 33.33%  of the attacks occurred in the perpetrators residence,  86.67% of the attacks were penetrative, 46.67% of the victims kept quiet, only 40.0% of the cases were reported to the police, 26.67% reported to hospital within 24 hours, 60% of the attacks were by acquaintance while 80% of the attacks were perpetrated by one assailant. Those who presented within stipulated time received appropriate  treatment interventions including PEP (46.67%). Only age had statistically significant association with rape (p=0.03).

CONCLUSION:The prevalence of rape among adolescent girls in the study, especially younger adolescents, is high. This portends devastating consequences on the psychophysical health of adolescent girls in the society. It calls for concerted effort from stake holders in adolescent care to be more proactive in working to ensure that sexual  assault against adolescent girls is averted.
Schistosomiasis: Review of an immune complex disease
Authors: Yusuf EO
Published: November 2023

BACKGROUND: Morbidity due to human schistosomiasis is associated with host immune responses which result in immune based inflammation, granuloma formation and fibrotic lesions.

MATERIALS AND METHODS: This is a review of the literature on the immunology of schistosomiasis and the description of the immunopathogenesis of the disease. Relevant articles were retrieved using electronic search and hand search of published literature.

RESULTS: Host responses which include immune based inflammation, granuloma formation and fibrotic lesions are aimed at destroying schistosome ova lodged in the liver, intestinal and bladder walls, and other tissues. At the site of the infection, ‘swimmers’ itch is due to physical damage to the skin by proteases and other toxic substances secreted by cercaria. During intestinal Schistosomiasis, the parasitic ova are lodged in the liver provoking fibrogenesis, while during urinary schistosomiasis pathology is attributed to the formation of granuloma along the urinary tract, there is fibrosis which lead to strictures, calcification and urodynamic abnormalities. The classic descriptions of schistosomiasis-related morbidity focus on pathologies unique to schistosome infection: periportal fibrosis for intestinal schistosomiasis and bladder deformity and hydronephrosis for urogenital schistosomiasis.

CONCLUSION: This review provides some useful information concerning some aspects of the relationships between Schistosoma species and the human host.

Biodisponibilidad del zinc
Authors: Paredes Guerra Gloria , Bolaños Díaz Rafael
Published: November 2023

La deficiencia marginal de zinc (déficit sub-clínico de zinc) ha sido reconocida como una condición muy prevalente en diferentes regiones del mundo. La absorción intestinal de zinc se efectúa mediante un mecanismo de transporte facilitado, mediado por una proteína de absorción a nivel de la vellosidad intestinal. La carga de zinc por dosis tiene importancia cuando se busca eficacia de la absorción de este elemento. El mecanismo saturable de su absorción explica la existencia de una relación inversa entre las cargas orales de zinc y su absorción intestinal. Las cargas excesivas de zinc por dosis condicionarían una pérdida innecesaria del micronutriente por saturación del mecanismo de absorción, siendo importante fraccionar racionalmente la dosis total diaria para obtener una mayor eficacia en su absorción. Se considera que la fibra a menudo ejerce un efecto negativo en la absorción de zinc; no obstante, este efecto se debe generalmente al hecho que la mayoría de los alimentos que contienen fibra también contienen un importante contenido de fitato. Es bien sabido que los fitatos ejercen un efecto inhibitorio sobre la absorción de zinc. Parece muy poco probable que el calcio per se tenga un efecto negativo en la absorción de zinc y, de igual manera, las cargas habituales de zinc en la dieta difícilmente afectarían de manera significativa la absorción de calcio. Diferentes estudios han evaluado la interacción de estos dos micronutrientes no encontrando evidencia de algún efecto negativo de uno u otro elemento. La absorción de hierro a partir de una comida estandarizada se reduce significativamente con la ingesta concomitante de carbonato de calcio o de hidroxiapatita; en contraste, la absorción de zinc no se afectó con los suplementos de calcio. Existe evidencia de una franca interacción entre hierro y zinc cuando se administran al mismo tiempo. Por tal razón, el suplemento conjunto de Zinc y Hierro es menos eficaz que suplementar ambos micronutrientes por separado. Existe una asociación significativa entre acidez gástrica y absorción de zinc, especialmente para aquellos compuestos poco hidrosolubles como el carbonato de zinc y el óxido de zinc. Por lo tanto, conocer la prevalencia de hipoclorhidria o de infección por H. pylori resulta de mucha utilidad para predecir el impacto del suplemento de zinc o de los programas de fortificación de alimentos. Por estas mismas razones, es preferible administrar los suplementos de zinc luego de la ingesta de alimentos para aprovechar la mayor acidez gástrica post- prandial y promover así su mejor absorción. De los compuestos de zinc, el sulfato de zinc y el óxido de zinc son los mejores prospectos para los programas de suplemento y fortificación debido a su relativo bajo costo. De estos compuestos, el óxido de zinc es el compuesto más estable y de menor costo.

La enfermedad neurológica aguda (ENA) grave en niños está asociada con significativa morbilidad, mortalidad y altos costos. Su prevalencia y desenlaces son desconocidos. El siguiente forma parte de un estudio multicéntrico internacional de prevalencia puntual, observacional y prospectivo (PANGEA). Objetivos: Determinar la prevalencia puntual y los desenlaces en niños con enfermedad neurológica aguda grave en la Unidad de Cuidados Intensivos Pediátrica (UCIP) del Instituto Nacional del Niño (INSN) en Lima - Perú.

Material y Métodos: Se realizó un estudio de prevalencia puntual en 4 fechas distintas en un periodo de 1 año (Noviembre 2011 - Noviembre 2012). La población del estudio estuvo conformada por niños de 7 días hasta 17 años de edad con enfermedad neurológica aguda grave hospitalizados en la UCIP del INSN en el periodo de estudio. Participaron los niños con enfermedad neurológica aguda debido a TEC, ACV, paro cardiaco, estado epiléptico, infección del SNC, TVM y niños con injuria cerebral crónica y enfermedad neurológica aguda concomitante; se excluyeron los niños con enfermedad neurológica perinatal aguda y niños con injuria cerebral crónica sin enfermedad aguda neurológica concomitante. Los resultados fueron presentados como promedios. Se consideró significativo un valor de p < 0.05.

Resultados: En el estudio global se enrolaron 961 pacientes de 126 UCIP ubicadas en 23 países. En la UCI del INSN se enrolaron 12 pacientes de 63 evaluados; las prevalencias en las 4 fechas fueron 25, 26.7, 12.5 y 12.5, respectivamente. Tanto de manera global como en la UCI del INSN el paro cardiaco fue la causa de enfermedad neurológica más frecuente; el 50% de pacientes con injuria neurológica aguda del INSN presentaron como desenlace discapacidad severa, en contraste con el 35% del estudio global. Tuvimos una estancia hospitalaria 3 veces mayor que en el estudio global. La mortalidad fue de 25%.

Conclusiones: Las enfermedades neurológicas agudas son una causa importante de mortalidad y morbilidad en niños. El PCR fue el evento causal de injuria cerebral más común. La mortalidad, estancia hospitalaria y frecuencia de secuelas severas es alta.

Published: November 2023

En Ecuador, los servicios farmacéuticos son limitados, por lo que se deben tomar medidas para aprovechar al máximo el potencial del profesional farmacéutico (PF) en la atención integral del paciente. La atención farmacéutica (AF) hospitalaria y comunitaria ofrece una plataforma sólida, en donde el consejo farmacéutico y la educación sanitaria actúan como herramientas claves para obtener mejores beneficios clínicos en cuanto al tratamiento.

El PF desempeña un papel esencial en la atención sanitaria, su participación contribuye significativamente en la promoción de la seguridad, calidad y eficacia de los tratamientos médicos, especialmente en situaciones de alta complejidad terapéutica como: polimedicación, medicamentos de estrecho margen terapéutico y enfermedades crónicas.

Además, se enfatiza la necesidad de imple- mentar estrategias como los criterios STOPP-START para mejorar la prescripción de medicamentos en adultos mayores y reducir los riesgos asociados. El presente artículo de revisión tiene como objetivo la descripción de estrategias de implementación y desarrollo en la atención farmacéutica para reforzar la seguridad del paciente y mejorar la calidad asistencial.

Published: November 2023

I denne rundbordssamtale, diskuterer vi forskellige former for kritik, historisk og aktuelt. Vi diskuterer, hvordan kritik er blevet noget uomgængeligt og allestedsnærværende, og hvilken problemer- og udfordringer det stiller til en kritisk praksis i dag. Vi skitserer to arketypiske kritikformer, som vi benævner som negativ og affirmativ kritik. Den negative kritik kan karakteriseres ved at afsløre, afdække og kritisere det bestående. Denne kritikform er væsentlig og afgørende både i samfundet og akademisk praksis. Vi diskuterer, hvordan en sådan negativ kritik dog også har sine begrænsninger. I det den ikke altid bidrager til at skabe forandring, men tværtimod kan skabe håbløshed, frustration og apati. Vi argumenterer for, at vi må udvide vores kritiske praksis og supplere med mere affirmative former for kritik. Affektive kritikformer, virker ikke ved at skrælle noget af, men i højere grad ved at lægge til. Det handler om at multiplicere, potentialisere, udfolde det virtuelle og bekræfte noget, der endnu er i tilblivelse. På den måde producerer de forskellige kritikformer også affektive fænomener som håb, begejstring, uhygge og vrede, ligesom kritikken selv kan udspringer af disse. En grundpointe er, at disse kritikformer ikke er modsætninger, men supplerer hinanden og at vi med dem kan udvide vores kritiske redskaber og måder at forstå og forandre verden på. Artiklen argumenterer ved at vise hvordan forskellige typer af kritik kan udfoldes i forhold til empiriske eksempler fra samfundsdebatter og forskningen, og diskuterer de forskellige opfattelser af kritik op mod centrale filosoffer, teoretikere og aktivister.
Resistenspunktet
Authors: Tobias-Renstrøm Sebastian , Køppe Simo
Published: November 2023

I denne artikel prøver vi teoretisk at give et bud på spørgsmålet om, hvorvidt subjektet rummer et samfundskritisk potentiale, når det nu produ- ceres i en samfundsmæssighed. Det gør vi primært ved at udlægge og videreudvikle freudo- marxisten Alfred Krovozas (1973) begreb om resistenspunktet. Resistenspunktet beskriver et emancipatorisk minimum, som etableres igennem den ikke-kumulative proces og svarer til det præ-kapitalistiske samfunds produk- tionsmåder i modsætning til den kumulative procestype, der karakteriserer kapitallogikken i kapitalismen. Igennem begrebet om neoteni påpeger vi, at den ikke-kumulative proces er en forudsætning for dannelsen af subjektets intrasubjektive struktur – dets ‘indre natur’. Vi sammenkobler dernæst resistenspunktet med Ødipuskomplekset for at vise, at der er to typer af kritisk refleksivitet på spil, når vi undersøger kritikkens udfoldelse; det kritiske forhold til, om man får det man vil have, og hvorfor man overhovedet vil have det. Vi peger ydermere på, at denne kritik sagtens kan rummes inden for en generel forståelse af kritikken som affirmativ (Raffnsøe, 2017) ved at pege på, at kritikken må være inden for rammerne af den samfundsmæssighed, som den udmøntes i, da den baserer sig på samme indirekte. Slutteligt kobler vi resistenspunktet op på begrebet om kollektivet for at demonstrere, at subjektet er sat i relation til kollektiver (Nissen, 2012), som i deres udfoldelse af bestemte praksisformer bevirker, at subjektet får en direkte erfaring med forskellige procestypers produktion og derved også med konflikterne imellem disse procestyper.
Els «personatges de carn i ossos». Domènec Guansé i els gèneres biogràfics
Authors: Isarch Antoni
Published: November 2023

El present article ressegueix l’atenció crítica de Domènec Guansé pels gèneres biogràfics al llarg dels anys vint i trenta del segle xx. D’una banda, s’hi analitzen els avantatges en termes de mercat editorial i de públic derivats de la incorporació de modalitats prosístiques en voga a Europa com les biografies novel·lades. De l’altra, s’hi consideren les relacions que aquests gèneres estableixen amb la novel·la, especialment pel que fa a l’obertura potencial de noves vies creatives que se situen en espais limítrofs entre la ficció i la no ficció. Finalment, es comenta la primera incursió biogràfica de l’autor, una obra dedicada a Pompeu Fabra que apareix el 1935.

Competitive approach to assessing the national security of the Russian Federation
Authors: Krupnov Yuriy A. , Sil'vestrov Sergei N. , Starovoitov Vladimir G. , Lapenkova Natalya V.
Published: November 2023

The object of the study is the procedure for assessing the state of national security of the Russian Federation, which is being considered for its improvement based on the implementation of a competitive approach when conducting assessments. The authors review the current procedure for assessing national security and justify the need for its improvement. A comparative analysis of domestic and international experience in the formation of criteria, the hierarchical structure of indicators and the prioritization of threats is carried out. The necessity of forming a hierarchical structure, universalization and integration of indicators as part of the implementation of a competitive approach in assessing the state of national security is substantiated. Particular attention is paid to studying the possibility of using uniform international criteria and a system of indicators in domestic practice. Based on the results of the study, the following conclusions are presented. The state of security is not an absolute value, but is characterized by relative indicators obtained from the results of a comparative assessment of the indicators of competing countries. Security monitoring and assessment should be carried out on a cross-country rating basis, comparing different countries, including countries whose activities are the source of the main challenges and threats. The novelty lies in the substantiation of the use of a competitive approach and rating methodology, allowing governing bodies to assess the state of security taking into account domestic development dynamics and a comparative analysis of the indicators of countries that can influence the state of security in Russia. Author also presented the associative series of national interests and national security indicators of the USA and Russia. In contrast to similar studies, an original approach to the formation of a set of indicators of the state of national security is proposed. Building a hierarchical structure of indicators provides an opportunity to focus on the most important international complex and integral indicators, and increase the efficiency and reliability of assessments. The main directions for improving assessment based on the implementation of structural-hierarchical and competitive approaches have been identified.
