Economic Tremors From a Perfect Storm: The Ukrainian Crisis and Its Impact on Regional Stock Market Volatility
Authors: OPRIȘOR Tudor , BALINT Cristina-Ioana , CORDOȘ George-Silviu 
Published: December 2024

This study investigates the impact of the Russia-Ukraine war on stock market volatility in neighboring countries, analyzing five stock market indices (BET, BUX, WIG, SAX, and MOEX) over a three-year period encompassing one year before and two years after the conflict’s outbreak. Employing four volatility estimators (Close-to-Close, Parkinson, Garman-Klass, and Rogers-Satchell), this research examines the evolution of market volatility and inter-market correlations. Findings reveal a general increase in volatility across most indices following the war’s commencement, with the MOEX index experiencing the highest turbulence. The concept of a “proximity penalty” is partially supported, as geographical closeness to the conflict zone does not uniformly correspond to increased volatility. Also, findings show an initial strengthening of correlations between markets in the first year of the war, suggesting a “contagion effect.” However, this is followed by a weakening of correlations in the second year, indicating a potential “decoupling effect” as markets begin to respond more to local economic conditions. These results have significant implications for investors, policymakers, and risk managers, highlighting the need for dynamic portfolio management strategies, tailored policy responses, and flexible risk models that can adapt to changing market conditions during prolonged geopolitical crises. This study contributes to the existing literature by extending the temporal scope of analysis beyond the immediate aftermath of the war’s outbreak and providing insights into the “proximity effect” in the context of a major European conflict. The observed patterns of initial volatility spikes followed by varying degrees of persistence and changing correlation structures offer a nuanced picture of how geopolitical events impact financial markets over time, emphasizing the complex interplay between political events and financial market dynamics.

Decreases in hemoglobin and hematocrit may signal degree of hemorrhagic shock: retrospective evaluation in a dog model
Authors: Jahr Jonathan S. , Dang Jonathan , Tong Ashley , Iskandar Stephanie , Patel Anamika , Grogan Tristan , Hopster Klaus , Driessen Berndt , Gunther Robert A. 
Published: December 2024

Abstract

OBJECTIVE
Data were extracted from preexisting published studies and evaluated retrospectively to compare lactate and base deficit values at baseline and posthemorrhage with changes in corresponding hemoglobin (Hb) and Hct measurements to assess any association of such changes with severity of hemorrhage over time. To understand the goal, the objective of this study was to demonstrate statistical changes in laboratory values as described above.

METHODS
Previous prospectively designed experiments on 120 mixed-breed dogs were conducted. Various parameters, including Hb and Hct, lactate concentration, and base deficit, were extracted from the previously mentioned experiments. To validate this retrospective study, subset data on heart rate and arterial pressure were compared. In a subset analysis, 60 experiments were extracted to compare baseline mean arterial pressure to posthemorrhagic values to prove the validity of this model. Published studies were evaluated retrospectively to compare lactate and base deficit values at baseline and posthemorrhage.

RESULTS
Arterial pressure is lowest posthemorrhage, increases, then stabilizes. Baseline Hb averaged 15.1 g/dL and Hct 43.4%, and posthemorrhage values averaged 12.1 g/dL (Hb) and 35.3% (Hct). Significant differences were observed for both Hb (3.0 g/dL difference; P < .001) and Hct (8.3% difference; P < .001) posthemorrhage. Lactate significantly increased (2.1; P < .001), and base deficit significantly decreased (5.2; P < .001).

CONCLUSIONS
The data collected retrospectively validated the model for significant hypotension. It was then possible to evaluate whether Hb and Hct may accurately predict the degree of hemorrhage. In this model, both Hb and Hct decreased posthemorrhage significantly, although the actual change in Hb and Hct posthemorrhage was modest. Lactate concentration increased, and base deficit decreased.

CLINICAL RELEVANCE
The data suggest that Hb, Hct, lactate, and base deficit should be studied to see if they may have a potential role in guiding resuscitation decisions.

Published: December 2024

Abstract
This study evaluated the efficiency of different Selenium supplements on blood Se status and reproductive performance of carp broodstock. Female carp (n=120) were distributed in 4 groups supplemented with Se as follows: control (non-supplemented), sodium selenite 200 µg/kg feed, sodium selenite i/m injection (160 µgSe/kg bodyweight), and selenized yeast 200 µg/kg feed. Blood was sampled on days 1, 20, and 30. On day 30, samples of roe were taken from females, and samples of blood and milt from 10 unsupplemented males. Larvae samples were taken after hatching. Plasmatic Se concentration was 51.38±3.77 µg/kg (day 1) and did not vary significantly. The erythrocyte Se concentration increased from 14.04±3.05 µg/kg (day 1), reaching 90.58±12.43 (day 20), to 212.38±57.87 µg/kg (day 30). Plasmatic glutathione peroxidase activity in supplemented groups increased from 4.41±1.15 to 7.73±2.26 μkat/L and plateaued until day 30. A similar pattern was observed for erythrocyte glutathione peroxidase activity, ranging from 54.51±15.45 μkat/L (day 1) to 80.72± 6.82 μkat/L (day 30). Se concentration and selenoenzyme activities in males did not differ from the female control group. Roe Se content ranged from 48.26±17.53 μg/L in control to 65.68±34.39 μg/L in fish supplemented selenized yeast, and in the pooled larvae samples, ranged from 26-43 μg/L. The Se concentration in the milt was 24.78±4.27 μg/L. Results suggest that 250 µgSe/kg feed was sufficient to meet the requirements of mature carp, sodium selenite being more efficient in elevating blood Se concentrations and selenoenzymes activities, while selenized yeast being more efficient in roe and larvae.
This time is different? Lessons from past reform initiatives in the Irish health system
Authors: Weir Stephen 
Published: December 2024

Abstract
The publication of the Sláintecare report in May 2017 is a landmark in Irish healthcare policy. For the first time in the history of the state, the Irish political system produced an agreed long-term vision for the health system. The Irish healthcare system has attracted considerable negative comment over a long period and satisfactory healthcare reform had appeared to be impossible to achieve. The history of Irish healthcare reform is replete with policy difficulties. This paper seeks to assess the likelihood that Sláintecare will be implemented given that it is the first long-term, multielectoral cycle healthcare initiative that is agreed by all the main political parties. The paper uses a game theoretic model developed by Dal Bó, Dal Bó, and Di Tella to develop an understanding of the impact of the electoral cycle on politicians and interest groups in negotiating and implementing healthcare reform. It uses a case-study methodology, with previous Irish healthcare reform initiatives as the unit of analysis. Finally, it shows that politicians are at a distinct disadvantage due to the short-term horizon imposed on them due to the electoral cycle and that the adoption of a long-term agreed policy, like Sláintecare, is more likely to be implemented.
Are Lough Neagh and the rights of nature the unfinished business of ‘the peace process’?
Authors: Doran Peter 
Published: December 2024

Abstract
This article outlines the background to an emergent all-island movement advocating for recognition of the rights of nature – including calls for recognition of Lough Neagh’s right to participate in its community ownership – and proposes that these developments could prefigure a far-reaching transition in our regard for our island home and all its subjects, including the more-than-human. Noting the significance of the fact that prominent voices in the Irish rights of nature movement originated in the borderlands of Derry and Donegal, the paper proposes that the plight of the iconic Lough Neagh in particular presents an unprecedented opportunity for governments in Dublin, Belfast and London to address a blind spot at the heart of the Anglo–Irish ‘peace process’, that is our regard for the intrinsic rights of the land, the waters, and all the communities of species who constitute our island home to flourish. With Ireland’s celebrated eco-philosopher and mystic, John Moriarty, the emergent movement is behind the call to enfranchise the earth and everything in it.
Protecting National Honor: Advocating for Legislation Against Cyber Hate Targeting Pakistan’s Armed Forces
Authors: Ali Muhammad Imran 
Published: December 2024

Abstract
Cyber hate constitutes a great danger for the Armed Forces of Pakistan, being the reason for diminishing the reputation and culture of discipline among the forces while influencing the general opinion of civilians. Through the discussion of cyberattacks on the military, this article focuses on the ludic nature of military cyberattacks and underlines the necessity for legislative intervention. Lack of respective laws is the main factor behind online defamations and misinformation spread by the Armed Forces. Applying analogy to foreign experience, the article advocates for the implementation of integrated regulatory measures targeted at digital violence. Proposed models provide for jurisprudence and policy principles to provide for strong legal mechanisms that would help formulate holistic national approaches to safeguard the Armed Force’s honor, dignity, and reputation. Nevertheless, these solutions are short of the desired outcomes due to the already highlighted challenges, such as enforcement. The solution to facing these challenges should be to adopt legislative reforms as the main route to maintaining the respect of the Pakistan Armed Forces. Effectively, the reforms can lead the country to stand firmly against the threats that are inherent in the future.
Factors that Influence Counterproductive Behaviors in Military Organization
Authors: Rusu Raluca 
Published: December 2024

Abstract
The main objective of the present study is to identify and analyze the factors that predict counterproductive behaviors in the military organization, specifically among military students. A quantitative research design, based on data collection through multiple measurement scales, was used to achieve this goal. The measurement scales used to analyze the organizational predictors of counterproductive behaviors were: the Organizational Constraints Measurement Scale (Spector & Jex, 1998), the Interpersonal Conflict at Work Measurement Scale (Spector & Jex, 1998). And perceptions of organizational justice were measured by the Distributive and Procedural Justice Measurement Scale, which was developed by Niehoff & Moorman (1993). The data analysis measured the correlation (using SPSS we calculated the coefficient of determination, denoted R2, which represents the proportion of the variation in the dependent variable that is predictable from the independent variables) between a number of predictors, namely interpersonal conflict, perceptions of procedural and distributive organizational justice, and organizational constraints and counterproductive behavior. The analysis was carried out comparatively on students from faculties belonging to “Nicolae Bălcescu” Land Forces Academy of Sibiu. In constructing the sample, we used a probabilistic stratified sampling, reaching a number of 137 students. The results show as that high levels of interpersonal conflict and organizational constraints are associated with variations in counterproductive behaviors, but low levels of distributive justice and procedural justice do not have a significant impact on these behaviors according to the data presented.

Authors: Herda Roman , Slivanský Miloš , Sandanus Jaroslav 
Published: December 2024

Abstract
The paper deals with the modelling and analysis of a single layer timber gridshell produced by active bending. Two geometrically nonlinear calculation methods, the Newton-Raphson method and the Modified Newton-Raphson method, are compared for the suitability of active bending modelling. The calculation is presented using the results of the timber lamella bending model. With this analysis, a more stable convergence of the calculation was achieved with the modified Newton-Raphson method than with the Newton-Raphson method. Based on the obtained results, the research was subsequently extended to the bending model of a single-layer network of timber beams, while the applied deformation method was the compression of supports. The suitability of using the modified Newton-Raphson method was verified on the model of a single-layer beam network, and the results were evaluated on five beam network models with different values of initial imperfection. During the processing of the parametric study, two methods of deforming the beam net in its supports were compared. The first method of shaping the beam mesh was the applied load using nodal forces. The second method of shaping the beam network was applied load using nodal displacements.

Authors: Salih Sarah R. , Shafiqu Qassun S. Mohammed 
Published: December 2024

Abstract
This study was to investigate the influence of adding optimum percentages of gypsum (G) - lime (L) mixtures (i.e. 6% lime and 4% gypsum) with three percentages of fly ash geopolymer (FAG) (i.e. 6%, 9%, and 12%) on some engineering properties of expansive soil. The tests results indicated that adding the percentages for the gypsum-lime mixture (6% lime + 4% gypsum) affected the soil’s properties by decreasing the plasticity index, swelling potential, and swelling pressure by 48.2%, 85%, and 87.9%, respectively. Adding (6% L + 4% G + 12% FAG) decreased the plasticity index, swelling potential, and swelling pressure of prepared expansive soil by about 66.1%, 96.4%, and 96.9%, respectively. The California bearing ratio increased up to 33.3% and 95.1% with the addition of (6% L + 4% G) and (6% L + 4% G + 12% FAG), respectively. Also, adding the same percentages of gypsum-lime mixture and gypsum-lime mixture with geopolymer caused increasing in Unconfined compressive strength value by 109.5% and 322.6%, respectively. The results show the significant effect of gypsum-lime mixture with geopolymer on compaction parameters of the prepared soil, so there was a decrease from 22% to 18% for the optimum moisture content and an increase from 1.473 g/cm3 to 1.516 g/cm3 for the maximum dry density.

Published: December 2024

Abstract
Due to its large activity and raw material use, construction offers great recycled material potential. Demolition and construction waste affect the cycle. Broken window glass powder can replace self-compacting concrete due to its pozzolanic properties. This study will quantify high-strength self-compacting concrete’s compatibility and mechanical characteristics (HSSCC) with varied amounts of waste glass powder. This study explored using limestone powder with 0.46 µm waste glass powder (WGP) as a filler in self-compacting concrete (SCC) mixtures. Waste glass powder (WGP) was tested as limestone filler powder replacements at 25%, 50%, 75%, and 100% by weight. Waste glass powder (WGP) was tested on compatibility with self-compacting concrete (SCC). This was done via slump flow, L-box, T500, and V-funnel testing. Furthermore, compressive, splitting tensile, and flexural strengths were to be assessed. SCC with WGP at varied replacement percentages had good flowability, passing ability, and viscosity in newly mixed concrete. Due to its filler effect and pozzolanic activity, WGP improves self-compacting concrete (SCC) compatibility and mechanical qualities. The efficiency of WGP replacement was substantially higher at 50%, resulting in a more marked influence on enhancement, particularly among those in older age groups.

Published: December 2024

Abstract
In a world where many new concepts and phenomenon have emerged, cities are the first territorial entities to be concerned and impacted by changes in their various spatial, social, economic, political, urban planning and environmental components. In this article, we focus on the urban evolution of Rabat, a city with historical, political, social, economic and environmental issues at stake.
As the capital of Morocco, Rabat enjoys many qualities and advantages in terms of its urban evolution, but this development is not without setbacks. An attractive post-Protectorate city is one that suffers from rural exodus, insecurity, urban pockets and so on. With this in mind, in this article we will try to visualize Rabat’s urban evolution using a cartographic approach based on time sequences, in an attempt to answer the question: What are the stages in Rabat’s evolution, and where is it heading?

Published: December 2024

Abstract
The advances in geodesy that are continually occurring allow the science of investigating the Earth’s shape and size to be applied to the observation of its geodynamics as well. Space geodesy and remote sensing methods enable the desired phenomenon to be observed with high precision and at different scales, where the phenomenon can be global or local in nature. By tracking changes in the position of unique points on the Earth’s surface using space geodesy methods (GNSS – Global Navigation Satellite System, VLBI – Very-long Baseline Interferometry, SLR – Satellite Laser Ranging, DORIS – Doppler Orbitography and Radiopositioning Integrated by Satellite), it is possible to indirectly track the movement of the Earth system and describe changes, anomalies and their evolution over time.
The main objective of the article is to define and describe the tectonic plates’ movement based on the selected approach and analysis, compare the results with conventional tectonic boundaries definition and support the anomalous outcomes for discrete locations by ongoing tectonic phenomena over the time period under study. By implementing space geodesy data into deformation analyses, the aim is to demonstrate the geodynamic contribution of space geodesy in studying and monitoring the geodynamics of the Earth system.

Environmental Benefits of Turbo Roundabout: A Case Study of Noise and Air Pollution Modelling in the Village of Košťany Nad Turcom, Slovakia
Authors: Jandacka Dusan , Cingel Andrej , Brna Matej , Cingel Michal 
Published: December 2024

Abstract
Road transport represents a significant source of environmental pollution by air pollutants and noise. An important task is therefore to find ways to reduce these negative impacts. One option is also to change the conditions of the road transport infrastructure, for example by re-arranging the spatial layout of intersections and thus changing the driving mode of vehicles. The task of this study is to analyze the impact of the potential reconstruction of the intersection on the noise and air pollution load in its surroundings using modelling with the CadnaA program. This is a proposal to change the intersection (PK) to a turbo roundabout (TOK), with a specific structural layout and driving mode. As part of the study, a traffic survey was carried out to obtain detailed information about the volume and directions of road traffic at the intersection. The traffic volume at the intersection is specific to a high proportion of trucks, which also significantly affected the (un)change in the environmental load by noise and emissions. From the modeled variants, a reduction in noise pollution was observed, but no significant positive change in air pollution was demonstrated at TOK. At the observation point MP1, an increase in noise by 2 dB was recorded, and at MP4 a decrease of 3.6 dB. PM10 concentrations did not decrease at any observation point and increased most at MP1 by 7 µg/m3 according to the model.
