Examining the Interface between Bureaucratic Leadership and Nation-building in Africa
Authors: Igbokwe-Ibeto Chinyeaka Justine
Published: July 2024

Background: Most countries in Africa are heterogeneous in nature, as reflected in their ethno-religious, linguistic and cultural diversities. Very few countries in the continent of Africa enjoy homogeneity in terms of customs, religion, and ethnic groups, among others. Unlike some countries in Europe that share many things in common and have been able to enjoy relative peace and development over time, Africa has been a hotbed of crises and conflicts.
Aim: Within the framework of the Theory of Integration, this article examines the interface between bureaucratic leadership and nation-building in Africa, with reference to Nigeria. The aim is to identify the challenges facing this country in its efforts at nation-building.
Method: The article adopts a qualitative approach and is descriptive in nature, with the researcher setting out to illustrate the association that exists between dependent and independent variables. Authoritative scholarly sources were reviewed during a desktop study. The purpose was to identify the relevant publications and apply them in the research.
Results: This article argues that Nigerians, in particular, and Africans, in general, do not seem to really desire a change of leadership that could enhance nation-building. If its leaders are bad, it is because they (the electorate) support them.
Conclusion: Building administrative capacities is key to resolving the myriad of challenges facing bureaucratic leadership in nation-building in Nigeria. The activities of government are increasing by the day and are getting more complex, but the available skilled and experienced administrators are far behind what is required at any given point in time.
The Future of the Past: The Preservation of and Access to Oral History Records at Pietermaritzburg Archives Repository, South Africa
Authors: Malokotha Mbongeni Tembe , Nsibirwa Zawedde
Published: July 2024

Abstract
Preserving and providing access to oral history records poses several challenges, including the need for significant resources, fragility, a lack of standardisation in the quality of carriers, legal and ethical considerations, access barriers because of factors such as language, limited resources for transcription and translation, and restrictions on access to protect privacy or confidentiality. Technology obsolescence is a further significant challenge to preserving and accessing oral history records. This study investigates the preservation of and access to oral history records at the Pietermaritzburg Archives Repository. A qualitative approach was used, and data were collected using semi-structured interviews from purposively selected staff members of the Oral History Unit (OHU). Content and thematic analysis were used to analyse the data. The findings revealed that the key challenges include the outdated provincial archives legislation, an absence of policies and strategies in place, an adapted building, lack of relevant qualifications, lack of training, scarcity of equipment and resources, and inadequate funding. Based on the issues identified, various strategies and recommendations are provided.

Authors: Osagie Onome , Oladokun Bolaji
Published: July 2024

This study investigated the usefulness of Artificial Intelligence (AI) in record-keeping in libraries. The objectives of the study were to analyse current trends in AI applications for record-keeping in libraries, evaluate the effectiveness of AI in protecting library records from physical and digital threats, explore the impact of AI on the efficiency and accuracy of record management in libraries, and identify potential factors that may limit the implementation of AI in library systems. Using a qualitative research approach, the study reviewed existing literature and case studies to assess AI’s contributions and limitations in library settings. The literature search was conducted using three major academic databases: Google Scholar, ResearchGate, and Emerald. These databases were selected based on their comprehensive coverage of scholarly articles, ease of access, and relevance to the fields of information science, library science, and technology. The findings revealed that AI significantly improves the automation of cataloguing and metadata management, thus reducing human error and increasing operational efficiency. AI also enhances the preservation of both digital and physical records through real-time monitoring and automated repair solutions. Additionally, AI-powered search engines provide more relevant and accurate search results by leveraging natural language processing and semantic search capabilities. However, the study also highlights challenges such as data quality issues, data privacy, biases in AI algorithms, and staff and user resistance. The policy implications include the necessity for funding and regulatory support, while practical implications involve the adoption of AI tools and staff training. For librarianship, adapting to new AI technologies and advocating for ethical AI use are essential.

Loss of lateral femoral condyle following sepsis of knee region in infancy: The hypothesis of vascular pathogenesis and clinical course
Authors: Agarwal Anil , Jethwa Ravi
Published: July 2024

Complete loss of lateral femoral condyle of the femur following sepsis of the knee region in infancy is a well-recognized entity. The etiopathogenesis of the sequelae is poorly understood with synovial plicae and post-septic growth disturbance postulated as possible causes. Two illustrative cases are presented to elucidate the clinical effects of condylar loss in the pediatric age group.There is a typical pattern of unicondylar damage, loss of adjacent metaphysis, and metaphyseal spur in involved cases. Abnormal loading of the knee, ligament laxity, and the presence of a physeal bar contribute additionally to deformity. The deformity progression can be as rapid as 2.8 degrees per month. The lesion is most often treated by balancing the knee mechanics using osteotomies and growth modulations. The lesion progresses downhill due to the absence of lateral support of the knee joint configuration. The anatomical region supplied by the superior lateral genicular vessels closely matches with the lateral unicondylar femoral loss seen post-sepsis. A vascular etiology is therefore hypothesized for the lesion.

Published: July 2024

Параметры ветровых волн, развивающихся на акватории водохранилищ, оказывают влияние на надежность эксплуатации гидротехнических сооружений. Определение реакции конструкций, расположенных на акваториях водохранилищ, на волновую нагрузку является основой расчета прочности сооружений гидроузлов. Динамический характер волновых нагрузок вызывает рост напряжений в конструкции, что при длительном периоде эксплуатации сооружений может служить причиной их разрушения. Оценка параметров ветровых волн, развивающихся на акватории водохранилищ, влияющих на силовое воздействие воды на погруженные конструкции, определяет устойчивость и степень надежности функционирования гидроузлов. В связи с этим в работе произведена автоматизация вычисления распределений направления и скорости ветра во времени на акватории водохранилища на основе модели Вейбулла в среде MathCad, что позволило построить графики изменения величины и направления скорости ветра на акватории Чебоксарского гидроузла в зависимости от месяца года. Обработка исходных данных произведена на основе сплайн-аппроксимации коэффициента вариации скорости, величины и направления вектора скорости дрейфа волнения. В результате определена плотность распределения давления поверхностных волн в зависимости от частоты при различных скоростях волн. Произведена оценка воздействия волны синусоидальной формы на формирование сил, поддерживающих плавающие тела. Вычислены геометрические параметры поверхностных волн на основе решения дифференциального уравнения второго порядка.

Wind-generated waves in the water surface of reservoirs affect the reliable operation of hydraulic structures. Determining the structural response to the wave load is necessary to calculate the strength of hydrosystem structures. The wave load has a dynamic nature and increases the stress in hydraulic structures, which can cause their destruction during a long period of operation. Assessment of parameters of wind-generated waves, which affect the water force action on hydraulic structures submerged in water reservoirs, is important to determine the stability and reliability of operation of hydrosystems. Therefore we automated the calculation of wind direction and velocity distributions in time based on the Weibull modelin MathCad. This enabled us to plot changes in the wind direction and velocity in the Cheboksary hydrosystem water area, depending on a month. The initial data were processed based on a spline approximation of a velocity variation coefficient, a wave drift velocity, and a wave drift direction. As a result, a surface wave pressure distribution was determined depending on the frequency at different wave velocities. The effect of a sinusoidal wave on the formation of forces supporting floating bodies was estimated. Geometric parameters of surface waves were calculated based on the solution of a second-order differential equation.
Impact of Dumpsite-Derived Compost on Heavy Metal Accumulation in Cultivated Maize and Spinach.
Authors: Gideon Mathew , Dennis Ambo Samuel
Published: July 2024

In many agricultural settings, the high cost of inorganic fertilizers has led farmers to resort to using compost from large dumpsites for soil amendment, in some cases, farmers even level smaller dumpsites and utilize the land for crop cultivation. This study investigated the concentrations of trace metals (Cd, Cr, Cu, Mn, Ni, Fe, Pb, Zn) in dumpsite compost, soil for cultivation, maize plants, and spinach vegetables. The study results revealed significant variations in heavy metal levels across the different samples analysed. Dumpsite compost exhibited elevated concentrations of Cd (6.00 mg/kg), Cr (89.00 mg/kg), Cu (21.00 mg/kg), Mn (101.00 mg/kg), Ni (17.12 mg/kg), Fe (1570.02 mg/kg), Pb (29.31 mg/kg), and Zn (315.18 mg/kg), surpassing the EU limits for Cd, Cu, Ni, Pb, and Zn. Conversely, soil for cultivation showed low concentrations of heavy metals, for Cd is (0.40 mg/kg), Cr (21.31 mg/kg), Cu (1.72 mg/kg), Mn (12.98 mg/kg), Ni (2.43 mg/kg), Fe (520.11 mg/kg), Pb (0.98 mg/kg), and Zn (67.31 mg/kg), still exceeding EU limits for Cd, Cr, Mn, Ni, and Zn. Maize plants and spinach vegetables showed varying levels of heavy metals, with concentrations generally lower than those in dumpsite compost but still exceeding the EU limits for several metals. The metal uptake by plants followed the order Cd > Pb > Cu > Ni > Cr > Zn > Fe > Mn. Thus, this study underscores the potential health risks associated with consuming crops grown on heavy metal loaded compost/soil and highlights the importance of continuous monitoring and remediation efforts to ensure food safety and environmental health.

Published: July 2024

Shape symmetry breaking in the formation of inorganic nanostructures is of large current interest. It was typically achieved through growth of colloidal nanoparticles with adsorbed chiral molecules. Photochemical processes induced through asymmetric plasmon excitation by circularly polarized light in surface immobilized nanostructures also led to symmetry breaking. Here we show that chiral symmetry breaking can be achieved on randomly rotating gold@silver core-shell nanobars in colloidal solution, by means of circularly polarized illumination, where orientational averaging does not eliminate the symmetry breaking of an asymmetric plasmon-induced galvanic replacement reaction. Different morphological effects that are produced by circularly vs. linearly polarized light illumination demonstrate the intricate effect of light polarization on the localized plasmonic-induced photochemical response. The symmetry breaking becomes smaller in more symmetric geometrical shapes such as triangular nanoprisms and nanocubes, down to zero in spherical ones. The symmetry breaking rises when the nanobars are immobilized on a substrate and illuminated from a single direction.
Novel Clustering Algorithm Based on Dpc and Pso

Published: July 2024

Analyzing the fast search and find of density peaks clustering (DPC) algorithm, we find that the cluster centers cannot be determined automatically and that the selected cluster centers may fall into a local optimum and the random selection of the parameter cut-off  distance dc value. To overcome those problems, a novel clustering algorithm based on DPC and PSO (PDPC) is proposed. Particle swarm optimization(PSO) is introduced because of its simple concept and strong global search ability, which can find the optimal solution in relatively few iterations. First, to solve the effect of the selection of the parameter dc on the calculation density and the clustering results, this paper proposes a method to calculate that parameter. Second, a new fitness criterion function is proposed that iteratively searches K global optimal solutions through the PSO algorithm, that is, the initial cluster centers. Third, each sample assigned to K initial center points according to the minimum distance principles. Finally, we update the clusters centers and redistribute the remaining objects to the clusters closest to the cluster centers. Furthermore, the effectiveness of the proposed algorithms verified on nine typical benchmark data sets. The experimental results show that the PDPC can effectively solve the problem of cluster centers selection in the DPC algorithm, avoiding the subjectivity of the manual selection process and overcoming the influence of the parameter dc. Compared with the other six algorithms, the PDPC algorithm has a stronger global search ability, higher stability and a better clustering effect.

Evaluation of Forecasting Methods from Selected Stock Market Returns
Authors: Obulesu Varikunta  , Madhupathi Yeswanth
Published: July 2024

Forecasting stock market returns is one of the most effective tools for risk management and portfolio diversification. There are several forecasting techniques in the literature for obtaining accurate forecasts for investment decision making. Numerous empirical studies have employed such methods to investigate the returns of different individual stock indices. However, there have been very few studies of groups of stock markets or indices. The findings of previous studies indicate that there is no single method that can be applied uniformly to all markets. In this context, this study aimed to examine the predictive performance of linear, nonlinear, artificial intelligence, frequency domain, and hybrid models to find an appropriate model to forecast the stock returns of developed, emerging, and frontier markets. We considered the daily stock market returns of selected indices from developed, emerging, and frontier markets for the period 2000–2018 to evaluate the predictive performance of the above models. The results showed that no single model out of the five models could be applied uniformly to all markets. However, traditional linear and nonlinear models outperformed artificial intelligence and frequency domain models in providing accurate forecasts.

SOCIAL ANXIETY – AN IMPORTANT FACTOR IN LEARNING SUCCESS
Authors: MIHAI (CĂLUGĂRU) Adina
Published: July 2024

An important aspect of learning refers to the fact that the student is not only a cognitive entity, but manifests affective states, motivations, attitudes that influence learning both directly and indirectly. A prerequisite for the success of learning consists in the determination of the students’ state of readiness, assimilated as the level of psychoeducational development. The results of school learning must be viewed under two dimensions: one is informative and refers to understanding some useful information, some intellectual algorithms; the other is formative, and triggers, both the transformation of the student’s cognitive apparatus, and the formation and development of his/her personality. Social anxiety is a factor that can strongly condition success in learning, being the effect of personal, motivational factors, as well as external factors such as: group values, social representations, the richness, and variety of individual experiences allowed by the social environment (Negovan, 2007). In the present study, we have investigated whether there are significant correlations between the level of social anxiety and the students’ school results. 382 students between the ages of 11 and 14, of which 157 boys and 225 girls, from a secondary school in Bucharest answered questionnaires between April and May 2023. The school is located in the urban area, in Sector 3 of Bucharest, and the secondary school includes 17 classes. The students who attend this school come from the areas that are close to the school, making it a “neighborhood school”. The teachers are concerned with the students’ education that goes beyond the school routine, since the interest is not only in intellectual training, but also in socio-emotional development. The results demonstrate that there is a significant inverse correlation between the level of social anxiety and the students’ academic performance. The results of the present research reflect a concern of the community of teachers that seek to create optimal conditions for students to develop their innate potential for learning.
TRANSLATION AND TREASON: AN ANALYSIS OF POLICY DOCUMENTS ON THE USE OF DIGITAL TOOLS IN THE ROMANIAN SCHOOL COUNSELLING SYSTEM
Authors: IACOB Mihai
Published: July 2024

The analysis looks at the policy documents of the Centres for Resources and Educational Support regarding the use of digital technology in school counselling, as they were enacted at the beginning of the Covid-19 pandemic. For this task, I employed a framework provided by socio-material theories (Cooren, 2010; Latour, 2005). Policy documents are designed to be obligatory points of passage (Callon, 1986) for human and non-human actors to bind them together for common goals. They take on a life of their own, beyond what their authors intended, in what is termed textual agency (Cooren, 2004). Using controversies (Venturini, 2010) as a means of retracing agencies, I analyse the references to digital technology within two types of documents: the institutional development plan and the managerial plan. The results point towards the existence of a state of incontrovertibility regarding the use of digital technology within the school counselling system, which precludes human and non-human actors from entering a negotiation process led by service managers and sets the stage for subversive actions (Callon, 1986). The failure of the policy documents to set themselves as obligatory points of passage opens up the school counselling system to being governed through obligatory points of passage designed by other actors with non-transparent and divergent agendas.

Abstract
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on Lactococcus lactis DSM 34262 when used as a technological additive to improve ensiling of fresh plant material. The additive is intended for use in easy and moderately difficult to ensile fresh plant material for all animal species at a proposed minimum concentration of 1 × 108 colony forming units (CFU)/kg fresh plant material. The bacterial species L. lactis is considered by EFSA to be suitable for the qualified presumption of safety approach to safety assessment. The identity of the strain was established and no acquired antimicrobial resistance genes of concern were detected. Therefore, the FEEDAP Panel concluded that the use of the strain as a silage additive is considered safe for all the animal species, for consumers of products from animals fed the treated silage and for the environment. Regarding user safety, the additive containing Lactococcus lactis DSM 34262 should be considered as a potential skin and respiratory sensitiser, and any exposure through skin and respiratory tract is considered a risk. One preparation was shown not to be irritant to skin or eyes. However, the Panel cannot assess the irritation potential of other possible preparations. The FEEDAP Panel concluded that Lactococcus lactis DSM 34262 has the potential to improve the fermentation of the silage prepared from fresh plant material with a DM range of 30–35% at a minimum concentration of 1 × 108 CFU/kg fresh material.
Design optimization of a new cavity receiver for a parabolic trough solar collector
Authors: Adıyaman Gülden , Çolak Levent
Published: July 2024

The most important parameter affecting the optical efficiency, the upper limit for an overall efficiency of parabolic trough solar collector (PTC), is the net absorbed heat rate by receiver on which solar beam radiation is concentrated. The objective of this study is to propose and optimize a new cavity receiver used in PTC for increasing optical efficiency. Three different geometries (triangle, rectangle and polygon), aperture widths, heights and positions of cavity receiver are taken as optimization parameters. A design of experiments (DoE) approach is used to evaluate the effects of these parameters on the absorbed radiation heat rate by receiver at the same time. SolTrace is used to investigate the effects of these parameters by optical analysis. The results indicate that the optimum cavity geometry is polygonal, and the cavity depth and aperture both are equal to 0.05 m. Moreover, it is found that the most effective parameter is the position of the cavity receiver, and the optimum position is at the focal line of the parabolic concentrator. The highest absorbed radiation rate by the cavity receiver and the optical efficiency of the PTC are equal to 3241.99 W and 81.05 % respectively for the optimum cavity receiver design.
SCIENTIFIC AND TECHNICAL REVIEW OF NATURAL CAMEROONIAN BASED FOODS AND DEVICES FOR ADMINISTRATION BY ENTERAL TUBE FEEDING
Authors: Taga Maka Cybele , Nono Yvette Jiokap , Mbiatat Hilaire de Goethe
Published: July 2024

Enteral feeding is a medical indication for people who cannot, should not, or no longer want to feed themselves through their mouth, and thus use a tube for that. In some countries, local foods were used because of the high cost and low availability of imported pharmaceutical products. Unfortunately, the blenderized food used have uncontrolled nutritional composition, and are not fluid enough. It leads to the feeding tube clogging. Pharmaceuticals and enteral feeding devices can help the food to flow easily by gravity, and many of them are patented. Some food technologies for making fluid products are known and their operating conditions generally have to be found regarding the type of equipment and raw materials composition. Therefore, with an appropriate process, it is possible to obtain a food from local sources, flowing through an enteral tube feeding only by gravity assistance without clogging. This situation encourages innovations based on local foods, fluidification techniques defined for a process and delivery devices, for the formulation of an enteral food. But some administrative constraints regarding the implementation strategy onsite, are likely to hinder the availability of local enteral feeding products, needing the creation of new requirements. The aim of this review is to present the current problems by bringing out the scientific, technical and administrative knowledges of the existing situation, in Cameroon especially, in order to propose innovative solutions.
Comparing peer, ChatGPT, and teacher corrective feedback in EFL writing: Students' perceptions and preferences
Authors: Zeevy-Solovey Orit
Published: July 2024

The effectiveness of Written Corrective Feedback (WCF) provision in English as a Foreign Language (EFL) classrooms for enhancing students’ writing has been well-established. With the advent of various feedback modes in modern classrooms, this pilot study aims to explore EFL students’ perceptions and preferences regarding the effectiveness of three distinct feedback modes: peer feedback, artificial intelligence (AI), and teacher feedback. The study also aimed to determine the distribution of feedback across specific components of writing, while accounting for revisions made. Fifteen pairs of participants were assigned to complete a brief writing task, followed by receiving WCF from peers, an AI tool (ChatGPT), and the teacher. Subsequent revisions to their writing were made after each feedback mode. A qualitative approach utilizing a survey was used for data collection and analysis. Results indicated that participants perceived both ChatGPT and teacher feedback as effective, with peer feedback also being generally regarded as effective by most participants. Preferences leaned towards receiving teacher WCF, as well as a combination of teacher and ChatGPT WCF. Furthermore, the study identified the proportion of feedback allocated to specific writing components, with subsequent discussions regarding implications. These findings have potential implications for refining feedback practices within EFL classrooms.
Augmented linguistic analysis skills: Machine translation and generative AI as pedagogical aids for analyzing complex English compounds
Authors: Loock Rudy , Holt Benjamin
Published: July 2024

In this article, our aim is to assess the efficacy of machine translation tools and state-of-the-art generative AI platforms such as ChatGPT in fostering enhanced linguistic analysis skills among students in order to improve their understanding of the language. Our case study deals with the analysis of complex English compounds—a known challenge for French learners of English as a second language. Our investigation centers on students’ ability to identify the head noun within complex noun phrases, both in full sentences and in press titles. The study involved two distinct cohorts: students in their third and final year of an undergraduate program in applied foreign languages, and students in their second and final year of a master's program in professional translation. We evaluated the participants’ ability to identify head nouns—a necessary skill for comprehending complex noun phrases—under two conditions: (i) without the aid of any linguistic tools and (ii) with the assistance of machine translation outputs by a generic online translator. Subsequently, we explored the capabilities of advanced generative AI tools—in this instance ChatGPT—of correctly identifying head nouns. Our results show that students may benefit from the presence of machine translation outputs, albeit with varying degrees of success. Our experimentation with ChatGPT shows that, given appropriate prompts, the tool is capable of identifying head nouns, suggesting that generative AI tools may be a more effective tool in helping students analyze and understand complex noun phrases in English.

Mangroves are important ecosystems that provide a range of ecosystem functions and services that support livelihoods and the environment. Mangrove forests in Timor-Leste have been exploited since at least the 1940s for agriculture, timber, and clearing for settlements. Measurement of the distribution of mangrove vegetation was carried out at two observation stations, namely: Station I, located in Tibar Village; Station II and located in Ulmera Village. The determination of the research location was determined by purposive sampling after a survey was conducted. The results of vegetation analysis that has been done there are 4 types of mangroves found such as; Sonneratia alba, Rhizophora apiculata, Rhizophora mucronata and Brugueira cylindrica. Stand density at Tibar station is dominated by the type of Sonneratia alba having a density of 366.67 trees / ha with a species mastery level of 91.23 m2 / ha and has an INP value of 219.98%. In contrast to the results of observations in Tibar village, the density of stands at the Ulmera observation station, the Rhizophora apiculata species has a higher density of 511 trees/ha but the level of species mastery is dominated by the Sonneratia alba species of 53 m2/ha with INP = 116%. The density level is dominated by the Rhizophora apiculata species because in the middle zone the substrate is muddy, while in the outer zone directly facing the sea and always inundated with sea water, more Sonneratia alba species are found.

O quanto de emoções e sentimentos uma pessoa consegue sentir por segundo? No dia a dia ou em momentos que você se sente encurralada nas dificuldades do cotidiano? Será se existe alguém que saiba?
Bom, essas respostas eu também não sei te dizer, mas hoje você vai entender um pouco como funciona a mente de uma estudante de medicina durante as práticas em uma Unidade Básica de Saúde (UBS) pelo eixo Práticas de Integração Serviço e Comunidade (PIESC). Os protagonistas dessa história real são alunos e professores da Universidade Federal do Pará campus Altamira da Faculdade de Medicina. O PIESC tem como objetivo colocar os discentes em cenários de práticas reais, auxiliando o nosso raciocínio clínico com casos verídicos em nossa frente, os pacientes. Me diz se isso é moleza? Eu senti uma enchorrada de emoções todos os dias, por aqui não faltaram borboletas no estômago!
Conciliar os problemas familiares, pessoais e as demandas da graduação não é tarefa fácil, mas eu tento me desdobrar para dar o meu melhor. O melhor para quem eu irei atender, que precisa da minha ajuda, às vezes com apenas um atendimento humanizado e empático e outras com intervenções mais sérias. Esse portfólio vai te levar para dentro da minha mente e entender como ela funcionou durante o semestre, o que eu pensei e o que eu senti.

Authors: Foesch Elfride
Published: July 2024

O presente artigo foi direcionado para revisar aspectos do transtorno do pânico, destacando aspectos etiológicos, clínicos, sintomatológicos e neurobiológicos. Bem como avaliar os avanços já existentes quanto ao tratamento e delimitar marcadores fisiológicos que trazem prejuízos funcionais e psíquicos. A base de dados para a pesquisa literária foi fundamentada nas fontes Scielo, Pepsic, Lilacs, Revistas acadêmicas, Google Acadêmico e livros. A partir destas fontes, o que se objetivou foi caracterizar os sintomas da crise do pânico, buscar respostas sobre as distorções cognitivas provocadas pelas alterações estruturais cerebrais, as desregulações no sistema neurotransmissor, interpretações errôneas acerca das sensações corpóreas, bem como entender a interação entre fatores genéticos, de desenvolvimento, ambientais e psicossociais que resultam nestas alterações no funcionamento das áreas cerebrais envolvidas no surgimento do transtorno do pânico. Descrever os tratamentos farmacológicos e não farmacológicos com ênfase na terapia Cognitivo-Comportamental. Avanços nos estudos que utilizem técnicas de neuroimagem serão de grande auxílio para elucidar as alterações no circuito cerebral do transtorno do pânico, bem como o avanço no delineamento sobre novos estudos farmacológico e psicoterapêuticos para o seu tratamento.
Kína védelmi ipari bázisának és védelmi innovációs ökoszisztémájának értékelése
Authors: Budavári Krisztina
Published: July 2024

Napjainkban a globális biztonság legfontosabb kérdései közé tartozik Kína világszínvonalú védelmi technológiai hatalommá válása és annak globális következményei. Kína az 1960-as évektől, különösen 1999-től jelentős erőfeszítéseket tett a védelmi ipara fejlesztése érdekében, amely fő célja az volt, hogy önellátóvá váljon a fejlett fegyverek és technológiák terén. A 21. század eleje óta a kínai védelmi ipar a technológiai innovációk előtérbe helyezésével jelentős fejlődésen ment keresztül. A legutolsó védelmi stratégiájában Kína egy „új korszakra” készül, és az a célja, hogy ezeket a technológiai eredményeket integrálja a Népi Felszabadító Hadsereg képességeibe, olyan „világszínvonalú” haderőt hozva létre, amely ellensúlyozza az Amerikai Egyesült Államok hagyományos katonai fölényét. A védelmi ipara fejlesztésével kapcsolatban azonban számos jelentős kihívással is szembe kell néznie, amelyeket az eddigiekben még nem sikerült leküzdenie.
Biztonság, piacgazdaság matematikai megközelítése (A hadfelszerelési igények tervezésének alapjai)
Authors: Bencsik Gábor
Published: July 2024

Legyen szó bármelyik nemzetről, a szembenálló felek határozott érdeke, hogy felülkerekedjenek a másik félen és győzelemmel zárják az ütközetet. Az úgynevezett „harc” összetételét és lehetséges kimeneteleit számos tudós próbálta definiálni, matematikai formába önteni. 1914-ben F. W. Lanchester több, differenciálegyenleteken alapuló matematikai modellt javasolt a harci helyzetek leírására, melyet érintően az alábbiképpen fogalmazott: „a fegyverek hatékonysága nem hagyható figyelmen kívül”. A harc kimenetelét befolyásoló tényezők vizsgálata nemcsak, hogy elegendő, de minden körülmények között szükségszerű. A befolyásoló tényezők között azonban számolnunk kell a közgazdaságtanban csak erőforrások szűkösségeként megjelenő korlátozó tényezővel. Jelen írásban a szerző a biztonsági dimenziók, a piacgazdasági lehetőségek és a matematikai törvényszerűségek között barangolva kínál az olvasó számára betekintést a harc megvívásához kapcsolódó tervezési nehézségek útvesztőibe.
