Investment In Defence Research Articles

Концептуальные и стратегические направления повышения экономической безопасности, как фактор устойчивого развития предприятий

Improving economic security is a complex task that requires a comprehensive approach. As you know, the most important and most expensive resource is information, it is not for nothing that they say: "Whoever owns information owns the world." With the constant development of technology and an increase in the volume of digital data, information security is becoming an important competitive advantage, plays a significant role and underlies the economic sustainability of enterprises. Information security in the field of economics covers a wide range of issues, ranging from investments in cyber defense to the consequences of cyber attacks on financial markets. The article examines the main aspects of economic relations in the field of information security, as well as its impact on the national and global economy.

Testing intra-species variation in allocation to growth and defense in rubber tree (Hevea brasiliensis).

Plants allocate resources to growth, defense, and stress resistance, and resource availability can affect the balance between these allocations. Allocation patterns are well-known to differ among species, but what controls possible intra-specific trade-offs and if variation in growth vs. defense potentially evolves in adaptation to resource availability. We measured growth and defense in a provenance trial of rubber trees (Hevea brasiliensis) with clones originating from the Amazon basin. To test hypotheses on the allocation to growth vs. defense, we relate biomass growth and latex production to wood and leaf traits, to climate and soil variables from the location of origin, and to the genetic relatedness of the Hevea clones. Contrary to expectations, there was no trade-off between growth and defense, but latex yield and biomass growth were positively correlated, and both increased with tree size. The absence of a trade-off may be attributed to the high resource availability in a plantation, allowing trees to allocate resources to both growth and defense. Growth was weakly correlated with leaf traits, such as leaf mass per area, intrinsic water use efficiency, and leaf nitrogen content, but the relative investment in growth vs. defense was not associated with specific traits or environmental variables. Wood and leaf traits showed clinal correlations to the rainfall and soil variables of the places of origin. These traits exhibited strong phylogenetic signals, highlighting the role of genetic factors in trait variation and adaptation. The study provides insights into the interplay between resource allocation, environmental adaptations, and genetic factors in trees. However, the underlying drivers for the high variation of latex production in one of the commercially most important tree species remains unexplained.

The Developments in the Arms Market in the Context of the Military Conflict in Ukraine

The military conflict provoked by the Russian Federation in Ukraine has created major imbalances in international security. In this fluid and unpredictable security environment, the defence industry has reacted promptly, increasing production and export of military equipment and modern weapon systems to counterbalance the aggressive actions of the Russian Federation. The data analysed indicate the Russian Federation’s continuing concern to make significant defence investments, including in the defence complex, which reveals its interest in continuing the military conflict in Ukraine. As for the Euro-Atlantic states, they are trying to counter the threat posed by the Russian Federation by supplying Ukraine with high-performance military equipment, while investing in their militaries to supplement the weapons supplied to Ukraine. After the outbreak of the military conflict in Ukraine, Romania has managed to increase its exports of arms and ammunition, creating favourable conditions for profitable partnerships with large companies in the Euro-Atlantic area. At the same time, Romania has increased its defence budget allocation to 2.5% of GDP, and there are discussions to further increase this percentage in the coming period. A substantial part of this budget allocation is earmarked for the procurement of modern military equipment to NATO standards for the Romanian armed forces.

Poor shoot and leaf growth in Huanglongbing-affected sweet orange is associated with increased investment in defenses.

Citrus disease Huanglongbing (HLB) causes sparse (thinner) canopies due to reduced leaf and shoot biomass. Herein, we present results demonstrating the possible mechanisms behind compromised leaf growth of HLB-affected 'Valencia' sweet orange trees by comparing morphological, transcriptome, and phytohormone profiles at different leaf development phases (1. buds at the start of the experiment; 2. buds on day 5; . 3. leaf emergence; 4. leaf expansion; and 5. leaf maturation) to healthy trees. Over a period of 3 months (in greenhouse conditions), HLB-affected trees had ≈40% reduction in growth traits such as tree height, number of shoots per tree, shoot length, internode length, and leaf size compared to healthy trees. In addition, buds from HLB-affected trees lagged by ≈1 week in sprouting as well as leaf growth. Throughout the leaf development, high accumulation of defense hormones, salicylic acid (SA) and abscisic acid (ABA), and low levels of growth-promoting hormone (auxin) were found in HLB-affected trees compared to healthy trees. Concomitantly, HLB-affected trees had upregulated differentially expressed genes (DEGs) encoding SA, ABA, and ethylene-related proteins in comparison to healthy trees. The total number of cells per leaf was lower in HLB-affected trees compared to healthy trees, which suggests that reduced cell division may coincide with low levels of growth-promoting hormones leading to small leaf size. Both bud dieback and leaf drop were higher in HLB-affected trees than in healthy trees, with concomitant upregulated DEGs encoding senescence-related proteins in HLB-affected trees that possibly resulted in accelerated aging and cell death. Taken together, it can be concluded that HLB-affected trees had a higher tradeoff of resources on defense over growth, leading to sparse canopies and a high tree mortality rate with HLB progression.

How to get your board and executive team cyber-ready and achieve a culture of cyber security from the board down: The CEO Method™ for breach prevention

Most boards and executive teams do not know how to achieve a culture of cyber security in their organisations, which puts company assets and ROI at risk. Many also do not know how to behave securely in all areas of their lives, much less what their role in driving the cyber security strategy of their organisation is or should be, which further drives up the risk. Given that culture always starts at the top, this paper teaches CEOs, board chairs, their CISOs, as well as other board directors, C-suite executives and their Investors, the CEO-driven yet decentralised, board-down method for breach prevention, getting all board directors and C-Suite executives cyber-ready to execute their part and creating a culture of cyber security from the board down, thus also helping organisations alleviate the pressure on CISOs as the focal point of creating and sustaining cultures of cyber security and serving as an indispensable complement to CISOs’ work of cyber-securing the IT and OT infrastructure of organisations. This method, called The CEO Method™, was invented by global tech and defence investment banker, entrepreneur, US Congressional adviser, Wharton and Harvard alum Andrzej Cetnarski, Chairman, CEO and Founder of Cyber Nation Central®, global cyber security protocol education, insights and advisory company dedicated to creating cyber-secure-by-design boards, executive teams and organisations. Cetnarski invented The CEO Method™ and its protocol process in response to a fatal breach of his first venture, where even the most cyber-secure technology and best-performing CTO were not able to prevent a breach caused by lack of understanding by the board, C-suite and blue-chip investors of what a true culture of cyber security entailed, allowing the threat actors to take advantage of the still-very-typical-of-boards-and-investors-today gap in cyber security knowledge and awareness, further exacerbated by a still-CISO-centric approach to cyber security. In so doing, this paper also teaches its readers the process for bridging the widening gap between CISO, regulatory compliance and technology as ‘the answer’ versus actual hacker-deterrent cultures of decentralised cyber security, individual ownership of cyber-specific fiduciary roles and tactical responsibilities, ‘partnership with’ instead of ‘over-reliance on’ the CISO and mastery of individual risk and response, individual cyber security and organisational cyber-strategy and each board director’s and executive’s role in it. This paper covers the answers to ‘Why and how should CEOs, board chairs and CISOs treat breach prevention readiness differently than they are now?’, ‘Why and how is the core concept of cyber security different than what most boards and C-suites think it Is?’ and ‘What do boards and C-suites need to be doing differently to close the gap between the 37.5 per cent chance of breach and US$10mm average cost of breach and actual breach deterrence?’

Emergence of games from ecological trade-offs: longevity changes strategies for extra-pair mating in birds

Each member of a breeding pair benefits if the other does more of the parental investment, so there is scope for behaviours that can be interpreted as both cooperative and competitive games between males and females. Extra-pair mating, widespread among socially monogamous birds, adds extra conflict but also potential opportunity to these social interactions. We analyse an individual-based model of a social environment with simple behavioural strategies where game-like patterns and cooperative outcomes emerge. The model focuses on three evolving traits: female propensity for extra-pair copulations and male investment in territorial behaviour and care. Male traits are reaction norms that use experienced within and extra-pair copulations as information input. We found that female extra-pair mating provided incentives for males to reduce territorial aggression and increase care for offspring. However, when adult survival was higher, male investment in care and territoriality changed from being negatively to positively correlated. This happened because longer life expectancy gave more behavioural opportunities for males, where nest desertion maximises lifetime male fitness when female extra-pair copulation is high. This outcome evolved gradually, with stable periods of intermediate extra-pair mating and low territoriality. These were punctuated by cycles of high extra-pair mating, nest desertion, reduced extra-pair mating and relapse to aggressive territoriality before a new stable phase was established. Each successive trait cycle was faster and smaller, indicating that through evolution of reaction norms, the gene pool has a long history that canalizes the evolution of behaviours, which can be interpreted as emergence and refinement of frequency-dependent games.Significance statementMost birds that mate in monogamous pairs engage in extra-pair copulations. Males of some species invest (in varying proportions) in offspring that are genetically related only to their social female. The great variability of extra-pair mating levels among different species and populations, supported by numerous field studies, indicates that social and ecological factors play a crucial role in shaping the behaviour. We analyse a computer model in which extra-pair mating evolves concurrently with male reproductive investments in territory defence and offspring care and show how common ecological trade-offs may change the social dynamics within a breeding population and lead to the emergence of complex social interactions between males, females and their neighbours.

India’s defence-industrial partnership with the UK

India and the United Kingdom have described an ambitious agenda for increasing defence-industrial cooperation, but almost no such engagement has occurred in practice. This is due in large part to India’s strong protectionist policies, which are meant to defend domestic industries and encourage the development of indigenous defence capabilities. These policies include rules that restrict foreign investment in defence, regulate the ownership of intellectual-property rights and define the amount of indigenous content that must be used in defence manufacturing.

The Evolutionary Ecology of Plant Chemical Defenses: From Molecules to Communities

Classic theory relates herbivore pressure to the ecology and evolution of plant defenses. Here, we summarize current trends in the study of plant–herbivore interactions and how they shape the evolution of plant chemical defenses, host choice, and community composition and diversity. Inter- and intraspecific variation in defense investment is driven by resource availability. The evolution of defenses at deeper nodes of plant phylogeny is conserved, yet defenses are highly labile at the tips. On an ecological timescale, while greater specialization of tropical herbivores enhances local diversity by reducing the performance of plants with similar defenses, in temperate ecosystems with more generalist herbivores, rare defense profiles are at a disadvantage. On an evolutionary timescale, host choice by herbivores is largely determined by plant defenses rather than host phylogeny, leading to evolutionary tracking by herbivores rather than cocladogenesis. The interplay between plants and herbivores shapes both the origin and maintenance of diversity.

Security in the Context of Sustainability: The Implications on Defence Expenditures

Abstract This scientific article aims to assess the link between defence expenditures and sustainable development in Romania. As the world faces increasingly complex security challenges and environmental concerns, it becomes crucial to examine the interplay between defence investments and sustainable development goals. The study focuses specifically on Romania, a country that has been undergoing significant economic and political transformations since joining the European Union. The analysis employs a comprehensive framework that integrates economic, social, and environmental indicators to evaluate the sustainability implications of defence expenditures. Using data from various sources, including national statistics and international databases, this study examines the trends in defence spending in Romania over a specified period. The research investigates the potential trade-offs between defence investments and sustainable development outcomes by considering key dimensions such as economic growth, social well-being, and environmental impact. By examining the case of Romania, valuable insights can be gained regarding the challenges and opportunities in balancing defence expenditures with sustainable development priorities. The study not only provides a comprehensive analysis of the current situation but also identifies potential pathways for enhancing the sustainability of Romania’s defence sector. This study contributes to the broader discourse on sustainable security fostering a more resilient and sustainable future.

Evolutionary signatures of a trade-off in direct and indirect defenses across the wild grape genus Vitis.

Evolutionary correlations between chemical defense and protection by mutualist bodyguards have been long predicted, but tests of these pattern remain rare. We use a phylogenetic framework to test for evolutionary correlations indicative of trade-offs or synergisms between direct defense in the form of plant secondary metabolism, and indirect defense in the form of leaf domatia, across 33 species in the wild grape genus, Vitis. We also performed a bioassay with a generalist herbivore to associate our chemical phenotypes with herbivore palatability. Finally, we tested whether defensive traits correlate with the average abiotic characteristics of each species' contemporary range and whether these correlations were consistent with plant defense theory. We found a negative evolutionary correlation between domatia size and the diversity of secondary metabolites in Vitis leaf tissue across the genus, and also that leaves with a higher diversity and richness of secondary metabolites were less palatable to a generalist herbivore, consistent with a trade-off in chemical and mutualistic defense investment. Predictions from plant defense theory were not supported by associations between investment in defense phenotypes and abiotic variables. Our work demonstrates an evolutionary pattern indicative of a trade-off between indirect and direct defense strategies across the Vitis genus.

Trade-offs in non-native plant herbivore defences enhance performance.

Non-native plants are typically released from specialist enemies but continue to be attacked by generalists, albeit at lower intensities. This reduced herbivory may lead to less investment in constitutive defences and greater investment in induced defences, potentially reducing defence costs. We compared herbivory on 27 non-native and 59 native species in the field and conducted bioassays and chemical analyses on 12 pairs of non-native and native congeners. Non-natives suffered less damage and had weaker constitutive defences, but stronger induced defences than natives. For non-natives, the strength of constitutive defences was correlated with the intensity of herbivory experienced, whereas induced defences showed the reverse. Investment in induced defences correlated positively with growth, suggesting a novel mechanism for the evolution of increased competitive ability. To our knowledge, these are the first linkages reported among trade-offs in plant defences related to the intensity of herbivory, allocation to constitutive versus induced defences, and growth.

Economic web-building behavior and behavioral investment trade-offs in a cobweb spider

Web-building spiders that build detritus-based bell-shaped cobwebs are model organisms for studies on behavioral plasticity because their web architecture components are easily quantified and behavioral investments are clearly separated. We investigated the web architectures and behavioral investments of the cobwebs built by Campanicola campanulata under different weight (heavy, medium, and light) detritus to research its cobweb architecture variation and analyzed the investment trade-off between foraging and defense. The results showed that spiders could actively choose lighter detritus to build retreats to reduce material and energy cost. There was a clear trade-off between defense and foraging investment of spiders choosing different weight detritus for their webs. The total length of gumfooted lines (foraging investment) was longer for the spiders that chose lighter detritus, but the energy expenditure during web-building (defense investment) was higher for the spiders that chose heavier detritus.

Group size rather than social status influences personal immune efficacy in a socially polymorphic bee.

The evolution of group living is associated with increased pressure from parasites and pathogens. This can be offset by greater investment in personal immune defences and/or the development of cooperative immune defences (social immunity). An enduring question in evolutionary biology is whether social-immune benefits arose in response to an increased need in more complex societies, or arose early in group living and helped facilitate the evolution of more complex societies. In this study, we shed light on this question through investigating how immunity varies intraspecifically in a socially polymorphic bee. Using a novel immune assay, we show that personal antibacterial efficacy in individuals from social nests is higher than that of solitary individuals, but that this can be explained by higher densities in social nests. We conclude that personal immune effects are likely to play a role in the social/solitary transition in this species. These patterns are consistent with the idea that social immunity evolved secondarily, following the evolution of group living. The flexibility of the individual immune system may have favoured a reliance on its use during the facultative phase early in social evolution.

Age-dependent resistance of a perennial herb, Aristolochia contorta against specialist and generalist leaf-chewing herbivores.

Plants need to balance investments in growth and defense throughout their life to increase their fitness. To optimize fitness, levels of defense against herbivores in perennial plants may vary according to plant age and season. However, secondary plant metabolites often have a detrimental effect on generalist herbivores, while many specialists have developed resistance to them. Therefore, varying levels of defensive secondary metabolites depending on plant age and season may have different effects on the performance of specialist and generalist herbivores colonizing the same host plants. In this study, we analyzed concentrations of defensive secondary metabolites (aristolochic acids) and the nutritional value (C/N ratios) of 1st-, 2nd- and 3rd-year Aristolochia contorta in July (the middle of growing season) and September (the end of growing season). We further assessed their effects on the performances of the specialist herbivore Sericinus montela (Lepidoptera: Papilionidae) and the generalist herbivore Spodoptera exigua (Lepidoptera: Noctuidae). Leaves of 1st-year A. contorta contained significantly higher concentrations of aristolochic acids than those of older plants, with concentrations tending to decrease over the first-year season. Therefore, when first year leaves were fed in July, all larvae of S. exigua died and S. montela showed the lowest growth rate compared to older leaves fed in July. However, the nutritional quality of A. contorta leaves was lower in September than July irrespective of plant age, which was reflected in lower larval performance of both herbivores in September. These results suggest that A. contorta invests in the chemical defenses of leaves especially at a young age, while the low nutritional value of leaves seems to limit the performance of leaf-chewing herbivores at the end of the season, regardless of plant age.

Defense investment and economy: a study on the causality relationship

The effect of defense expenditure on economic growth is the subject of many debates. This study investigates the relationship between defense expenditure and economic growth applying Granger causality test. To do this, data of military expenditure, gross domestic product, and gross capital formation from six countries are analyzed. They are: Brazil, China, United States of America, France, United Kingdom and Russia. The findings of the study indicate Granger causality relationship for some of these countries.

Efficient Adaptation to Flood Risk

This paper studies whether private adaptation to flood risk is economically efficient. We estimate the return to elevating houses, one of the most significant private defensive investments against flooding, using two decades of microdata on the universe of houses and flood damages in high-risk flood zones in the Atlantic and Gulf Coast United States. We find that undertaking adaptation is socially optimal in the highest-risk areas over a house's lifetime but that individual homeowners may underinvest in flood protection because the benefits do not accrue over their average tenure. We identify conditions under which adaptation yields the highest returns.

Development Status and Trend of Stealth Technology of Tactical Missiles

In modern warfare, precision guided munitions have become one of the major equipment to attack and hit the enemy’s crucial value targets. In addition, they are the critical targets of the missile defense and anti-aircraft interceptor system of varying countries during interception and destruction, and the world has increased investment in missile defense. Therefore, the penetration and countermeasures capacities of missiles holds the key to the victory, and the stealth technology of tactical missiles provides a vital orientation for the future advancement of weapons and equipment technology. Based on the current military requirements, this paper summarizes the application of stealth technology in varying tactical missiles and analyzes the development trend of such technology in the future, which is expected to have great implications for further research and application of both stealth and anti-stealth technology.

From self-interest to cooperation: extra-pair mating as a driver of relaxed territorial aggression in social neighbourhoods

In socially monogamous bird species, males and females tailor their reproductive strategies to that of the other. Interactions are complex, and have elements of both conflict and cooperation. Breeding process is further complicated with the occurrence of matings outside the pair bond, which is a frequent phenomenon in these species. Extra-pair mating has clear benefits for males, but cuckolded males may withdraw care and resources at a cost to females, which produces an unbalanced costs-to-benefits ratios within the mating pair. We used an individual-based model with social networks approach, to study how female extra-pair mating strategies may affect male investment in offspring care and territorial defence. In our model, extra-pair copulation rate is a female-driven strategy; we use two adjustable male traits—care and territorial defence—that co-evolve with that strategy and control the number of extra-pair copulations initiated by a social female. The model utilises very simple rules of behaviours between individuals that lead to the emergence of evolved changes in mating strategies on a large scale. We show how extra-pair copulations initiated by females in their neighbourhood can reduce territorial defence and wasteful aggression between the males across the whole population. We propose that female mating behaviour and male responses are flexible traits that might serve as potential drivers of the evolution of cooperation.

Dominant ecological processes and plant functional strategies change during the succession of a subtropical forest

Understanding community assembly process could enhance forest conservation and restoration, while which dominant ecological process drives the community assembly during forest succession is still controversial. In this study, the phylogeny-based and functional trait-based indicators were used to investigate the community assembly processes during forest succession in southern China. 30 dominant species and 33 functional trait indicators related to plant competition, reproduction, and defense strategies, 7 environmental factors related to light availability and soil nutrients, and species richness were selected to explore the dominant ecological processes during succession via Monte Carlo method, structural equation model, multiple linear regression, and one-way ANOVA analysis. Results showed that both the community phylogenetic and functional trait structures changed during succession. Phylogenetic structure clustering and functional trait clustering were evident in early succession. In middle succession, the phylogenetic structure and functional trait structure were randomly dispersed. In middle and later succession, the phylogenetic structure clustering, functional trait clustering, and functional trait evenly dispersed were found. The environmental factors, especially the soil P content, and species richness were found to have significant effects on the community assembly processes during succession. Dominant species in early succession always occupied acquisitive strategies and had high light-use ability and low investment in defense, but dominant species in later succession showed more conservative strategies and exhibited diverse defense strategy, reproductive strategy, and light and nutrient resource-use strategy, apparently in order to adapt changing and more complex environments. The results demonstrate that the relative importance of ecological processes changed during succession. Environmental filtering mainly dominated in early succession, and its strength gradually decreased as succession progressed. Both environmental filtering and competitive exclusion had important effects on community assembly in later succession. The assessment of the relative importance of ecological processes during succession could be biased if only based on one plant functional strategy.
