Monetary Policy, Uncertainty and COVID-19
Authors: PINSHI Christian P.
Published: October 2024

The COVID-19 pandemic is influencing the management of monetary policy in its role as regulator of aggregate demand and guarantor of macroeconomic stability. We use a Bayesian VAR framework (BVAR) to provide an analysis of the COVID-19 uncertainty shock on the economy and monetary policy response. This analysis shows important conclusions. The uncertainty effect of COVID-19 hits unprecedented aggregate demand and the economy. In addition, it undermines monetary policy action to soften this fall in aggregate demand and curb inflation impacted by the exchange rate effect. We suggest a development of unconventional devices for a gradual recovery of the economy.
Ravulizumab in adults and children with atypical hemolytic uremic syndrome: a plain language summary of three studies
Authors: Nowicki Michal , Printza Nikoleta
Published: October 2024

What is this summary about?

This summary gives an overview of three published articles that report the results of research studies of ravulizumab, an approved treatment for people with atypical hemolytic uremic syndrome (often shortened to aHUS). This is a rare and serious condition where blood clots form in small blood vessels. Blood vessels are structures that transport blood around the body. Blood clots are the body's way of stopping someone from bleeding too much. However, if they form when they are not needed, they can cause harm. In atypical hemolytic uremic syndrome, the blood clots can cause injury to organs like the kidney. In the three studies, the researchers wanted to know if ravulizumab could decrease the formation of these clots and improve kidney function.

Children who had never received ravulizumab or a similar treatment took part in the first study.

Adults who had never received ravulizumab or a similar treatment took part in the second study.

In the third study, children whose disease was already controlled by a medication called eculizumab switched to ravulizumab. Ravulizumab is dosed less frequently than eculizumab.

The researchers looked at kidney function and the levels of different blood components to see how well the treatment was working. They also monitored the adverse effects that participants experienced.

What were the results?

Across the three studies, ravulizumab improved indicators of blood clotting in small vessels and improved kidney function in both children and adults. In addition, ravulizumab was similarly effective to eculizumab for children who were already receiving eculizumab and switched to ravulizumab. Overall, the adverse effects that people experienced with ravulizumab were manageable.

What do the results mean?

These studies showed that ravulizumab is a treatment option for children and adults with aHUS. In addition, a switch to ravulizumab can be considered for children who are already responding well to eculizumab and would benefit from less frequent dosing.
Die Grundsicherung als Spielball – fachfremde und außergesetzliche Einflüsse auf das SGB II in rechtspolitischer Bewertung
Authors: Wentzel Joachim
Published: October 2024

Die deutsche Sozial- und Arbeitsmarktpolitik schaut auf eine sehr bewegte Dekade zurück, in der trotz stabiler wirtschaftlicher und arbeitsmarktlicher Verhältnisse exogene Faktoren die Sozialsysteme stark unter Druck gesetzt haben: Die 2015 beginnende erste große Fluchtwelle, die Corona-Pandemie und der Beginn des russischen Angriffskriegs gegen die Ukraine am 24.2.2022 mit in der Folge von bis zu einer Million geflüchteter ukrainischer Menschen in Deutschland. Die Grundsicherung nach dem Sozialgesetzbuch Zweites Buch (SGB II) war neben anderen eine der Säulen in der Bewältigung dieser Krisen.

Nichtsdestotrotz ist die Grundsicherung in der Sozial- und Arbeitsmarktpolitik eines der am meisten und am heftigsten diskutierten Bereiche: Arbeitsmarktzugang von geflüchteten Menschen, Bürgergeld, Leistungsminderungen und Sanktionsmoratorium, Diskussion „Arbeit muss sich lohnen“ oder Lohn-Abstands-Gebot etc. – all diese Themen werden in meist kurzer Abfolge hinter- oder auch nebeneinander im politischen Raum, der Presse und der Gesellschaft diskutiert. Dabei ist die Arbeit der Jobcenter mit ihrer Klientel (erneut) im Brennglas der Debatte.

Die Diskurse bleiben nicht ohne Auswirkung auf das SGB II selbst, die Einflussfaktoren sind immens. Infolgedessen unterliegt das SGB II einem ständigen Wandel und Anpassungen, was nicht zuletzt an der bloßen Anzahl an Gesetzesänderungen zu erkennen ist.

Dieser Aufsatz skizziert die wesentlichen politischen Einflussfaktoren auf das SGB II – jenseits der oben beschriebenen exogenen Faktoren – des letzten Jahres und sortiert diese sozial- und rechtspolitisch ein.
Der Kooperationsplan im Sozialgesetzbuch II – Die rechtliche Bewertung und die praktische Umsetzung
Authors: Jäger Melanie , Hökendorf Jörn
Published: October 2024

Seit über einem Jahr werden in den Jobcentern gemeinsam mit den Bürgergeldbeziehenden Kooperationspläne erstellt. Mit dem Bürgergeld-Gesetz sollte ein neues Eingliederungskonzept etabliert werden, welches die Handhabung erleichtert, da die zuvor bestehenden rechtlichen Anforderungen nach Einschätzung des Gesetzgebers der Praktikabilität entgegenstanden. Im Nachgang ergaben sich in der Literatur unterschiedliche Auffassungen zur Rechtsnatur des Kooperationsplans, welche aufgrund der grundsätzlichen Differenzen einer praktikablen Lösung entgegenstehen könnten. In der Rechtsprechung hingegen scheint die Neuregelung nicht angekommen zu sein, da bisher keine Entscheidungen in den großen Datenbanken veröffentlicht sind. Aufbauend auf diesen Feststellungen wollen wir die unterschiedlichen Literaturmeinungen kurz darstellen und klären, ob erst eine höchstrichterliche Entscheidung für einen rechtssicheren Umgang erforderlich ist. Beispiele für den Inhalt von Kooperationsplänen aus der Praxis und deren rechtliche Bewertung schließen unseren Beitrag ab.

Published: October 2024

The consumer-centric electricity market is the new paradigm in electricity market regulation in Europe. Small players such as prosumers and energy communities become increasingly important and call for a re-evaluation of the current ways to trade electricity. This work focuses on innovative ways to integrate small players in a regional context and identifies path dependencies in the existing legal framework that have historically supported a centralized market order in the electricity sector but now hinder the implementation of new approaches. With the proposal of an energy platform cooperative, an organizational model contributing to a just energy system transformation is presented.
Selektivität im Völkerstrafrecht
Authors: Patett Andreas
Published: October 2024

Modern international criminal law has been subject to accusations of selectivity since its inception. Double standards, victor's justice, the law of the strongest - these are the accusations. This study assumes that the application of international criminal law has always been selective and is likely to remain so, which is not necessarily a shortcoming. Decisive are the criteria according to which the selection takes place. The theories of punishment are used as a foundation for the assessment of various selection strategies. After examining this elementary topic, the study addresses the question arising from the accusation of selectivity: Does the selectivity of international criminal law cause the loss of its legitimacy?

“The substitution of one mental picture for another”
Authors: Flint Justice M. ,   Marquette University Press
Published: October 2024

This essay explores Mary Augusta Ward’s 1888 novel Robert Elsmere and its place in the complex, evolving religious landscape of the Victorian period, arguing that its narrative strategies are designed to persuade readers to agree with the beliefs of its protagonist not mainly through intellectual argument or emotional appeals, but through appeals to images. It contends that this image-based approach is key to the novel’s resonance, a resonance which suggests a counter to intellectually focused narratives of the Victorian faith crisis. Robert Elsmere establishes a model of belief that privileges the power of images over that of intellectual assent, offering readers a compelling glimpse into the inner world of a religious dissenter. Ultimately, it underlines the importance of imaginative identification with new religious images in facilitating the seismic spiritual changes of the Victorian period.
“Orbis Non Sufficit”
Authors: Wisniewski Mark ,   Marquette University Press
Published: October 2024

This paper uses the context of early modern English colonialism and empire building to propose a new reading of Francis Godwin’s The Man in the Moone. My reading of this text focuses on Godwin’s narrator, the Spanish picaro Domingo Gonsales, and postulates that the choice to fictionalize a Spaniard’s lunar voyage is deeply tied to Godwin’s personal anxieties over the state of Spanish colonialism and the nescient English Empire. By choosing a Spanish protagonist over an Englishman, Godwin is able to explore the logical conclusion of the Spanish imperial project—colonization that has subsumed terrestrial conquest and moved into the celestial spheres. When The Man in the Moone suggests that a Spaniard is already beginning to make the transition to extraterrestrial colonization, Godwin is forced to confront the possibility that an English alternative to Spanish colonialism may no longer be possible.

Published: October 2024

Context.—

Generative artificial intelligence (GAI) technologies are likely to dramatically impact health care workflows in clinical pathology (CP). Applications in CP include education, data mining, decision support, result summaries, and patient trend assessments.

Objective.—

To review use cases of GAI in CP, with a particular focus on large language models. Specific examples are provided for the applications of GAI in the subspecialties of clinical chemistry, microbiology, hematopathology, and molecular diagnostics. Additionally, the review addresses potential pitfalls of GAI paradigms.

Data Sources.—

Current literature on GAI in health care was reviewed broadly. The use case scenarios for each CP subspecialty review common data sources generated in each subspecialty. The potential for utilization of CP data in the GAI context was subsequently assessed, focusing on issues such as future reporting paradigms, impact on quality metrics, and potential for translational research activities.

Conclusions.—

GAI is a powerful tool with the potential to revolutionize health care for patients and practitioners alike. However, GAI must be implemented with much caution considering various shortcomings of the technology such as biases, hallucinations, practical challenges of implementing GAI in existing CP workflows, and end-user acceptance. Human-in-the-loop models of GAI implementation have the potential to revolutionize CP by delivering deeper, meaningful insights into patient outcomes both at an individual and a population level.

Dark Triad and Humor Styles: A Study on White Collar Workers from Türkiye
Authors: Ekizler Hüseyin , Bolelli Murat
Published: October 2024

Humor plays a crucial role in psychological functioning, influencing goal achievement, emotional regulation, and interpersonal interactions. This study explores the effects of dark triad on humor styles and to inquire about the inconsistent relations previously reported between narcissism and self-enhancing humor within a Turkish sample. Utilizing the Humor Styles Questionnaire and the Dirty Dozen Dark Triad inventory, data were collected from 468 white-collar employees working in various companies through online questionnaire. The results indicated that Narcissism positively affects all humor styles, while Psychopathy significantly associated with aggressive, self-enhancing and self-defeating humor. In contrast, Machiavellianism shows a negative effect with self-defeating humor. These findings underscore the complex interplay between personality traits and humor, suggesting that while Narcissism may enhance both positive and negative humor styles, Psychopathy predominantly influences negative styles, and Machiavellianism appears less involved. The study discusses the implications of these results and provides suggestions for future research.

Authors: Ehiwario, F. A.  , Onyemekonwu, R. C.  , Giweze, E. A.
Published: October 2024

The study examined Co-operators' perception towards cooperatives' involvement in agricultural extension delivery. Multi-stage sampling process was used to select 337 respondents sampled through the use of questionnaires. Descriptive statistical tools were used to analyse data collected while Logit regression was used to analyze the hypothesis. The results showed that 93.2% of the co-operators had a positive attitude towards cooperatives' involvement in extension delivery, while only 6.8% did not. The likelihood ratio or model chi-square was significant (chi-square = 95.49; df = 8; P<0.050) which indicated that the independent variables had a significant influence on co-operators’ perception of the involvement of cooperatives in agricultural extension delivery. Based on the result, educational qualification (b=-1.274), farming experience (b=-0.601), income (b=1.065), cooperative experience (b=-0.620) and co-operators attitude (b=-0.191) had a significant relationship with the co-operators perception towards cooperative involvement in extension service delivery. It was concluded that most co-operators have a positive perception toward cooperative involvement in extension service delivery; hence they are willing to accept extension programmes channelled through cooperative societies. The researchers recommended that co-operators should be trained to build their capacity in rendering extension services.

Published: October 2024

This study was carried out to analyze the factors influencing tomato marketing in Jalingo Local Government Area of Taraba State: A case study of CBN redesign of naira notes. Public opinion survey design was adopted for the study; multi-stage technique was used to select 100 respondents. Data for the study were collected from primary source with the aid of questionnaire. Descriptive statistic and multiple regressions were used to analyzed data. Results of the multiple regressions indicated that the major factors that significantly influenced the marketing of tomato are: annual income (0.390), scarcity of money (-989.943), low patronage (-6130.114) and high transaction charges (-205.636). During the redesign of the new Naira notes in Nigeria, various mediums of buying and selling were observed, as reflected in the provided table 1. The predominant mode of transactions (buying and selling of tomatoes) by tomato marketers was through cash transfer 96.0%. The result further showed that the major constraints faced by the tomato marketers were naira scarcity (100.0 %), low patronage (91.0%), transportation cost (94.0%), and failed cash transfer (93.0%).  Also, the major medium of buying and selling tomatoes explored by tomato marketers during the period of new Naira redesign are cash transfer (96.0%) and cash payment (90.0%) in the study area. It was concluded that tomato marketing was negatively and significantly influenced by the CBN redesign of naira currency which led to scarcity of money. It was recommended that government should be discouraged from formulating policy that will bring about scarcity of naira currency in the country as it affects marketing of tomatoes and also policymakers and stakeholders in the tomato marketing sector should focus on strategies to enhance income levels, address challenges related to low patronage, and provide financial support to mitigate constraints during periods of Naira redesign.

Authors: Banseka, R. F.  , Murtala, N.  , Sani, R. M.
Published: October 2024

The study was carried out to examine the impact of fadama III additional finance II on yield and income of faro-44 rice farmers beneficiaries in Taraba State, Nigeria. A Multi-stage sampling procedure was used to select 500 respondents. Data were analyzed using descriptive statistics (mean, frequency distribution and percentages) and inferential statistics (Gini coefficient). The findings of the study revealed that more days was expended in faro-44 rice weeding days per hectare with mean of 5.0 and 8.0 hours worked/day. The average number of tractors owned by the fadama users’ association (FUA) farmers was 2 with value of N3,129,079.63. The major inputs intervention received by the respondents were 5 kg seeds, wet season = 10 kg seeds all at N10,000/20 kg bag ((dry season), 2 bags of NPK fertilizer and 4 bags of NPK fertilizer at N7,000/50 kg bag in dry and wet season respectively, followed by a bag of Urea fertilizer in dry season and 2 bag of Urea fertilizer at N9,000/50 kg bag in wet season. Similarly, the respondents also received 4 liters of herbicides each in dry season and wet season. The result further revealed that the yield (kg/ha) in dry season increased from 3,675 kg before intervention to 6,156 kg after intervention representing 59.69% increase and with mean difference of 2,481 kg significant at P<0.01. Similarly, yields in wet season by the faro-44 rice farmers has a mean difference of 1,679 kg compared to mean difference of 2,481 yield in dry season. Consequently, income from dry season harvest (N/ha) increased by 40.77% representing Naira value from N787,375.00 to N1,720,400.00 for before and after fadama AF-II intervention. Similarly, income from wet season harvest only increased by 4.63% with wet season mean income difference of N315,189 compared to the dry season mean income difference of N933,025 implying that the respondents realized more income in dry season faro-44 rice farming than wet season in Taraba State, Nigeria. The study concluded that fadama III additional finance II project intervention had positive impact on yield and income of the respondents and faro-44 rice farming yielded more in dry season than wet season. It is recommended that farm inputs at subsidized rate should be made timely available, there should be further collaboration through the State fadama office with National Agricultural Land Development Authority (NALDA) to clear more land, rice promotion programmes like training on modern rice production techniques, new varieties of seeds in order to be technically efficient should also be promoted and farmers should be encouraged to form cooperatives to benefit more from such laudable fadama AF-II intervention and enjoy economies of scale.

The NA-DEL airfoil modifications for general aviation and UAV applications
Authors: Dančuo Zorana , Kostić Ivan , Kostić Olivera , Bengin Aleksandar , Vorotović Goran
Published: October 2024

This paper presents the NA-DEL geometric method for modifications of the so-called Dolphin family airfoils. Based on the original mathematical concept for Dolphin airfoils by Iosif Taposu, a new modification method was developed by the authors of this paper to achieve better aerodynamic efficiency than the original Dolphin airfoils and also their NACA geometrical counterparts. Bionic airfoils represent cutting-edge aerodynamic research. After the creation and integration of the natural optimization method-the semi-elliptical method, a new concept was introduced. The concept proposed that changing the shape of the leading edge of the original Dolphin airfoils could produce favorable outcomes in terms of aerodynamic efficiency. This method involves merging the two corresponding NACA and Dolphin airfoils to create a new hybrid airfoil in the leading edge zone. The NA-DEL method was tested both numerically and experimentally, and it showed noticeable improvements by modifying the airfoils of the 2410, 2412, and 2415 series. By numerical analyses, the NA-DEL 2410, 12, and 15 hybrid airfoils have been found to increase lift and lift-to-drag ratio, while also reducing drag in cases of standard roughness and MRe=6.0, which corresponds to the general aviation category. Through wind tunnel tests performed at the Belgrade University-Faculty of Mechanical Engineering, it has been discovered that the hybrid NA-DEL 2415 is also aerodynamically more effective than NACA and original Dolphin counterparts at a Reynolds number of 400.000. Results for this Reynolds number indicate that the NA-DEL airfoils are a suitable choice for fixed-wing UAVs and in that sense have potential military applications as well.

Modern approach to the aircraft design implies more often rescue system application to the aircrafts with human crew like gliders, ultra-light and trainer aircraft. Likewise different class of the UAVs is more commonly designed with the parachute, or parachute/airbag landing system. Whether the aim is to land UAV in a usual mission or to rescue the aircraft/UAV system and the crew, integration of the parachute system is the solution. This paper represents implementation analysis of the different rescue systems in the medium range UAV with the diverse aspects of limitations like minimum mass increase, limited free space in the UAV to place the system and minimum increase of the aerodynamic load.

Artillery rockets of medium and long range are used on the battlefield for indirect firing of distant targets. Having a large dispersion of hits, they are used for targeting surface areas from multitube launchers. At the same time, the line of sight of the target does not exist, so the firing elements are taken based on the known geographical coordinates of the target and the launcher, using the ballistic computer and firing tables. Long ranges, low initial velocity and long duration of the flight to the target make such rockets very sensitive to the impact of disturbances on the accuracy of hitting. As the range increases, the accuracy of rocket systems decreases more and more. At the same time, for effective coverage of the target area, a large number of rockets is counted. Firing a target area with a large number of rockets involves a statistical approach to determining the efficiency of the firing. Thereby, statistical indicators of the distribution of impact points are used, such as the circular error probable, which represents the radius of the circle that contains half of all hits. In addition to the number of rockets with which an area is targeted, the probability of destroying all targets in the area also depends on the radius of the lethal effect of the warheads. This paper presents determination of the probability of hitting and destroying a surface target.

This paper presents a novel system for accurately mapping military targets using a combination of trigonometry and computer vision, deployed through unmanned aerial vehicles (UAVs). The proposed system integrates a drone equipped with a camera and employes trigonometric principles to calculate target distances based on the drone's position, angles and elevation. Upon sighting a target, the system utilizes computer vision algorithms to precisely identify and localize it within the drone's field of view. Subsequently, leveraging the calculated distances and the drone's GPS coordinates, the system accurately maps the target's coordinates on a global positioning system (GPS). The integration of trigonometry and computer vision enhances target localization capabilities, facilitating efficient and precise mapping of military objectives in diverse operational environments. This system holds significant potential for enchancig situational awareness and operational effectiveness in military applications.
Effect of erosive burning in rocket motor on the ballistics of rocket flight
Authors: Stojković Srđan , Gligorijević Nikola
Published: October 2024

Erosive burning in solid rocket motor is a phenomenon that occurs at the beginning of the motor operation and represents an increase in the burning rate in the motor compared to the designed rate. The result of increased burning rate is an unwanted pressure increase in the motor, and thus thrust, which changes the designed flight parameters of the rocket. During development of the rocket motor, this problem should be solved constructively, if possible, by changing the shape and dimensions of the propellant grain and motor elements. If it is not possible, the designer tries to make the system capable enough to withstand pressure and thrust jumps without major disturbances, and to provide to achieve the reproducibility of this phenomenon. The paper presents examples of the impact of erosive burning onto the flight of some small-caliber unguided rockets, and also for one short-range guided missile, where this phenomenon is clearly expressed, but reproducible and acceptable. In this paper, the results obtained on the basis of measurements carried out by researchers from MTI, HK Krusik, MB-Lucani and the Vlatacom Institute were used. Measurements were made in static and dynamic conditions, in the laboratories of the mentioned companies. For the analysed guided missile, the shape of the propellant grain was reconstructed to avoid guidance and structural problems. Some examples of design solutions of the rocket propellant grain in order to reduce the occurrence of erosive burning are also presented.

Published: October 2024

Smoothed Particle Hydrodynamics (SPH), a computational method as part of ANSYS Autodyn software is widely employed for simulating natural fragmentation phenomena and all others process follow with large deformations. The goal of this study is to investigate the impact of particle size on key parameters such as fragment velocity and the total number of fragments. The research focused on the 105 mm M1 artillery projectile, aims to examine the relationship between particle size and fragmentation phenomena. The Johnson-Cook failure model was applied to the projectile case and Johnson-Cook strength model was applied to all metal parts of the artillery projectile. Furthermore, the research aims to underscore the importance of validation against available experimental data to ensure the reliability and applicability of SPH simulations. It is noted, however, that the available experimental results provide limited information. As a result, the comparison is restricted to the total number of fragments rather than a detailed analysis of fragment mass group numbers. Through systematic simulations with varying particle sizes, the study reveals a distinct trend: decreasing particle size correlates with increase of total number of fragments and no significant changes in fragment velocities within the specified material model behavior. By offering comprehensive insights into the relationship between particle size and fragmentation behavior, the study aims to emphasize the necessity of considering multiple factors in SPH simulations to enhance their accuracy and utility in predicting natural fragmentation phenomena.

Within this study, the process of forming explosively formed projectiles is analyzed. This type of warhead is used for military purposes due to its excellent impact performance. The projectile is shaped like a metal disc which, during the action of the explosive, forms into a high-speed projectile. Such formed projectiles act on the target. The performance of the projectile is influenced by a large number of parameters, such as structural characteristics and material properties. Using a numerical program on the EFP model, various parameters influencing the final shape of the projectile and thus its performance on the target can be analyzed. The parameters considered within this study are the type of explosive filling and the thickness of the copper disc. The analyzed disc thickness was 1-4% of the explosive filling diameter. It was observed that reducing the thickness of the projectile results in higher values of projectile stable velocity. Specifically, reducing the initial thickness of the projectile can replace the use of more explosive explosives, thereby reducing the overall mass of the construction.

Conventional black powder typically consists of charcoal, sulfur and potassium nitrate (KNO3). The use of other carbon-based substances instead of charcoal has been less common. Following the development of time delay pyrotechnic compositions in this research, the pyrotechnic properties of other carbon-based substances, particularly carbon black were studied. The use of charcoal has been widely spread due to its unique chemical composition and superior combustion properties. However, due to the specific production process and the selection of materials for producing charcoal, it is difficult to achieve the same quality, i.e., chemical composition of charcoal. The use of other carbon-based substances may suppress those problems. Quaternary compositions containing charcoal or carbon black as a fuel and KNO3, sulfur and phenol-formaldehyde resin were prepared and tested. Commercially available charcoal and carbon black were obtained for this initial research. The as-received materials, charcoal and carbon black, were characterized by SEM, EDS and particle size analyzer. SEM and EDS analysis were used to obtain information about morphology and semi-quantitative determination of the chemical composition and particle size analyzer for obtaining information about particle size and its distribution. The experimental values of heat of reaction and linear burning rate were compared. The average linear burning rate for pyrotechnic composition with carbon black of 7.33mm/s showed increase of 28.5% comparing to pyrotechnic composition with charcoal. Observed behavior suggests that this compound may be useful for a variety of pyrotechnic applications.

Published: October 2024

An artillery weapon that uses a precise Inertial Navigation System (INS) for orientation towards the North was considered. For this purpose, the axes of the INS must be aligned with the axes of the artillery weapons. If the axes of the INS are not well aligned with the axes of the weapon or if the axes of the barrel of the weapon is not perpendicular to the axis of elevation, then during the elevation of the axis of the weapon, an azimuth angle error may occur, which depends on the axis misalignments and the value of elevation angle. The result obtained by calculation based on spherical trigonometry and the results obtained by laboratory measurements are presented. The results obtained by calculation were confirmed by measurements. These results fully apply to rocket artillery. Tthe obtained result shows that the minimization of the INS installation offset is needed to reduce the error at larger azimuth angles.
