Authors: Bawa Iliya , Onuigwe Gladys , Abdulsalami Zainab
Published: May 2024

Banking sector reforms faced some difficulties despite its laudable achievement. In Nigeria, wrong perception and stiff resistance to the policy could potentially determine prospective investors in the banking industry. The objective of the study is to analyse banking sector reforms on Nigeria economic growth for competitive global market from 1981-2020. The study made use of secondary time-series data sourced from annual CBN statistical bulletin. Augmented Dickey Fuller (ADF) and cointegration test were employed to determine the existence of long run relationship among the variables. The study used Econometric View (E-view 12) for descriptive analysis of the variables. The findings revealed that among others that credit allocation to private sector had a statutory trend from 1981 to 2006 and later experienced a gradual upward movement from 2007 to 2020. This shows that banking sector has contributed to the real sector of the economy through credit given to private sector. It shows that credit is significant to economic growth. The study concluded and recommended that time lag should be permitted to exist from one reform period and the next reform period to allow for appropriate planning and as well policy consistency.

Two-stage fusion localization based on UWB/PDR/Geomagnetism in underground space
Authors: Li Jinkun , Xiu Chundi , Yang Dongkai , Selezneva Maria
Published: May 2024

A two-stage fusion positioning model based on UWB/PDR/Geomagnetism is proposed for pedestrian positioning in underground space. Firstly, an improved particle filter (PF) based on regional constraint is applied to PDR/Geomagnetism combination positioning, where the PDR positioning results are used to constrain the geomagnetic matching region. The proposed algorithm improves the inherent blindness of scattered particles of traditional PF, thus to enhance the positioning accuracy. Furtherly, Factor graph (FG) is used to fuse the output of PF above with the UWB positioning results, which effectively overcomes the serious problem of positioning hopping points caused by signal occlusion in some areas of UWB system. Experimental results show that the improved PF can outperform extended Kalman filter (EKF) for PDR/Geomagnetism combination positioning and FG algorithm can provide a higher positioning accuracy for UWB/PDR/Geomagnetism fusion positioning.

Multipath signals that impact positioning accuracy are progressively being utilized to recover land and ocean geophysical information with the introduction of Global Navigation Satellite Systems (GNSS). An interference signal-based approach is GNSS-interferometry reflectometry (GNSS-IR). In this work, interference signals are gathered for sea surface altimetry using a low-cost GNSS signal receiver outfitted with a right-handed circularly polarized antenna, which can reduce cost of tide measurement. This study decompose the raw signal-to-noise ratio and extracts several frequency components using an empirical mode decomposition technique. The vertical distance between the antenna phase center and the sea surface is then calculated using Lomb-Scargle periodogram after the spectra of various frequency components has been analyzed. The final inversion tide is then obtained by removing the wild spots using the sinusoidal fitting approach. According to the results, there is a 0.89 correlation between the measured and recovered tides, and the RMSE is 0.23 m.
Analyzing the Influence of Global Ionospheric Scintillation on GPS PPP during the Geomagnetic Storm of 26-28 February 2023

Published: May 2024

Geomagnetic storms, which follow solar activities like solar flares, coronal mass ejections, and high-speed solar wind streams, are significant disturbances in the global space environment. These storms occur when high-speed plasma clouds, generated by solar activity, reach the vicinity of Earth a few days later, causing disruptions in the Earth's magnetic field. This phenomenon is known as a geomagnetic storm (Gonzalez et al., 1994). Geomagnetic storms have a profound impact on GPS Precise Point Positioning (PPP) by amplifying and varying ionospheric delays in GPS phase and code data. This, in turn, affects high-precision GPS relative positioning (Odijk, 2001). In low-to-mid latitudes, geomagnetic storms can even cause disruptions in total electron content (TEC) and result in satellite signal loss (Astafyeva et al., 2014).
Three Attitude Models and their Characterization in the Generic Multisensor Integration Strategy for Kinematic Positioning and Navigation
Authors: Brunson Benjamin , Wang Jianguo
Published: May 2024

This research aims at further completing our novel Generic Multisensor Integration Strategy (GMIS) with the systematic development of three alternate attitude models, i.e., roll-pitch-heading (RPH), direction cosine matrix (DCM), and quaternion. The GMIS' potential for a true sensor level data fusion is leveraged to its full extent here by facilitating comprehensive error analysis framework in Kalman filtering. A comparative analysis between the solutions resulted from the GMIS associated with each attitude model have been analysed and compared through real road test data. The attitude models were found to perform very consistently, exhibiting the same behaviours in the residuals of the process noise and measurement vectors along with the estimated variance components. Besides, an analysis was conducted to investigate how each attitude model reacts to a sudden trajectory variation captured by the IMU. Each attitude model still performed consistently, but the DCM model in particular exhibited resistance to absorbing erroneous observations into its process noise estimates.

Aim: In this study, ultrastructural, chemical, and histological analyses of extracted deciduous teeth were performed to analyze the effect of two different types of glass ionomer cements used in association with selective caries removal in deep lesions of deciduous teeth. Methods: A clinical, ex vivo, longitudinal study was conducted. A total of 19 deciduous molars from 9 volunteer patients were used. The teeth were randomly restored with one of two types of glass ionomer cement following the selective caries removal technique. The groups were divided into a control group, which used Fuji IX (GC- Europe, Leuven, Belgium), and a test group, which used Maxxion R (FGM- Joinville, Santa Catarina, Brazil). After exfoliation, the teeth were stored at 4°C and subjected to scanning electron microscopy (SEM), optical microscopy (OM), and energy dispersive spectrometry (EDS). Results: EDS analysis revealed that calcium (Ca) and phosphorus (P) were present in 100% of the specimens in both the control and test groups. Fluoride was found in 60% of the control group specimens and 63% of the test group specimens. OM images showed areas of mineralized dentin in both treatment groups. Conclusions: Selective caries removal for deep lesions in deciduous teeth was shown to be a safe therapeutic protocol, demonstrating signs of dentin mineralization and control of disease progression.

Published: May 2024

L’utilisation d’agents virtuels (AVs) pourrait être un moyen de représenter la diversité  dans les technologies en santé mentale. Cependant, la perception de l’utilisateur envers les états  affectifs des AVs reste méconnue. Cette étude visait à déterminer si le choix d’un regroupement d’AVs d’apparences diverses module l’évaluation des états affectifs d’autrui et si le sentiment d’appartenance perçu entre les participants et les AVs explique cette relation. 44 participants  répartis aléatoirement en deux groupes devaient soit : 1) choisir un regroupement d’AVs ou ;  2) se faire imposer au hasard un regroupement d’AVs avec lesquels ils effectueraient la tâche d’évaluation d’états affectifs. Une adaptation du questionnaire Overlap of Self, Ingroup and Outgroup scale (OSIO) a été complété afin de mesurer le sentiment d’appartenance envers les  AVs. Des tests-t comparant les groupes sur la reconnaissance émotionnelle, l’évaluation du désagrément global et le sentiment d’appartenance se sont révélés non significatifs. Une analyse de médiation qui évaluait la contribution du sentiment d’appartenance sur la relation entre le choix d’un regroupement d’AVs et le désagrément global perçu s’est également révélée non significative. Le choix d’un regroupement d’AVs n’influence donc pas l’évaluation émotionnelle. La promotion de la diversité en santé mentale pourrait ainsi passer par l’exposition à des AVs d’apparences variées.

An Anzaldúan Triptych: with Homage to Federico García Lorca
Authors: Conner Randy P.
Published: May 2024

In perhaps her most well-known poem, “To live in the borderlands means you,” Gloria Anzaldúa insists that “hondenying the Anglo inside you / is as bad as having denied the Indian or Black.” That Gloria foregrounded her Chicana—or ChicanX—identity in her writings is indisputable, as even her title Borderlands: La Frontera: The New Mestiza indicates. I must admit, however, that sometimes it concerns me that, even if she played a role, perhaps unwittingly, in the construction of such, her identity has been largely reduced to that of “Chicana,” with “queer” occasionally thrown in for good measure, while other aspects of her complex identity—her Leftist politics, her Pagan spirituality, etc.—have been obscured.
Life Within and Beyond: The Legacy of Borderlands
Authors: Tovar Amanda Lee

Gloria Anzaldúa’s Borderlands/La Frontera: The New Mestiza celebrated its 30th anniversary in 2017, and as a commemoration of the innovative text, the University of Texas Rio Grande Valley’s Center for Mexican American Studies prepared a yearlong celebration in honor of its legacy. Many mujeres across a multitude of disciplines came together to coordinate events that ranged from poetry readings, symposia showcasing student research rooted in Anzaldúan theory, bilingual story hours, and the annual El Retorno: El Valle Celebra [a] Nuestra Gloria. This edition of Río Bravo, like the year itself, is dedicated in honor of Borderland’s legacy, which has provided all of us the space to examine our own borders for a deeper appreciation and critique, as well as the possibility for healing those heridas abiertas (Anzaldúa 3) that still exist and hemorrhage today.
Bedî‘ İlminde Eş Seslilik, Ses Özdeşliği ve Ses Benzerliği İle İlgili Söz Sanatları
Authors: Gezek Ahmet
Published: May 2024

Hicri yedinci yüzyıldan sonra klasik dönem tasnifinde bedî‘ ilminin, mana ve lafızla (söyleyişle) ilgili söz sanatları olarak iki kısımda değerlendirilmesi yaygındır. Lafızla ilgili sanatların kapsamı bir müelliften diğerine bazı farklı sanatları içinde barındırsa da bu sanatlar genel anlamda kelime tekrarı, kelimelerin yer değiştirmesi, bir kelimenin ibaredeki başka bir kelimeden türetilmesi, eş seslilik, ses özdeşliği ve ses benzerliği gibi konuları içerir. Çalışmamızda, lafızla ilgili sanatlar içerisinden eş seslilik, ses özdeşliği ve ses benzerliği ile ilgili olanlara yer verilmiştir. Bu açıdan konu incelendiğinde, cinasın bazı alt başlıklarının eş seslilikle, bazısının ses özdeşliğiyle, bazısının da ses benzerliğiyle ilgili olduğu tespit edilmiştir. Şöyle ki; cinâs-ı tâm’ın alt başlıklarından cinâs-ı mümâsil’de eş sesli sözcükler bulunmaktadır. Cinâs-ı müstevfâ ve cinâs-ı mürekkeb sanatlarında, telaffuzları aynı olduğu için iki kelime veya ifade arsında ses özdeşliği vardır. Ses benzerliğiyle ilgili söz sanatları; cinâs-ı gayr-ı tâm, seci ve lüzûm-ı mâ lâ yelzem’dir. Araştırmamızda, lafızla ilgili söz sanatlarının iki önemli konusu cinas ve seci ile ilgili farklı bir perspektif sunulmuş ve telaffuzla ilgili bu sanatların daha iyi anlaşılması hedeflenmiştir. Yapılan araştırmada, lafızla ilgili bedî‘ sanatlarını eş seslilik, ses özdeşliği ve ses benzerliği açısından ele alan çalışmaya rastlanmamasının konuyu daha önemli hale getirdiği düşünülmektedir.

Influences of sudden stratospheric warmings on the ionosphere above Okinawa
Authors: Hocke Klemens , Wang Wenyue , Ma Guanyi
Published: May 2024

Abstract. We analyzed the ionosonde observations from Okinawa (26.7° N, 128.1° E; magnetic latitude: 17.0° N) for the years from 1972 to 2023. Okinawa is in the northern low-latitude ionosphere, where the influences of sudden stratospheric warmings (SSWs) on the ionosphere are expected to be stronger than in the mid- and high-latitude ionospheres. We divided the dataset into winters with major SSWs in the Northern Hemisphere (SSW years) and winters without major SSWs (no-SSW years). During the SSW years, the daily cycle of the F2-region electron density maximum (NmF2) is stronger than in the no-SSW years. The relative NmF2 amplitudes of solar and lunar tidal components (S2, O1, M2, MK3) are stronger by 3 % to 8 % in the SSW years than in the no-SSW years. The semidiurnal amplitude, averaged across 29 SSW events, has a significant peak at the central date of the SSW (epoch time 0 of the composite analysis). The SSW influence is not strong: the semidiurnal amplitude is about 38.2 % in the SSW years and about 34.0 % in the no-SSW years (relative to the NmF2 of the background ionosphere). However, there is a sharp decrease in the amplitude of about 10 % after the SSW peak is reached. The amplitude of the diurnal component does not show a single peak at the central date of the SSW. We present the maximal semidiurnal amplitudes of the SSWs since 1972. The SSW of 31 December 1984 has the strongest amplitude (162 %) in the ionosphere above Okinawa (with a high geomagnetic activity, Ap, of 37 nT). The most surprising finding of the study is the strong lunar tides with relative amplitudes of about 10 % and the discovery of a terdiurnal lunar tide (5 %) in the NmF2 during the SSW years. The periods of the ionospheric lunar tides align with the periods of ocean tides and lunisolar variations in the atmosphere.
Quality assurance and quality control of atmospheric organosulfates measured using hydrophilic interaction liquid chromatography (HILIC)

Published: May 2024

Abstract. ​​​​​​​As a crucial constituent of fine particulate matter (PM2.5), secondary organic aerosols (SOAs) influence public health, regional air quality, and global climate patterns. This paper highlights the use of hydrophilic interaction liquid chromatography (HILIC) which effectively retains strongly polar analytes that might exhibit incomplete or no retention in reverse chromatography, resulting in superior separation efficiency. A HILIC column was used to analyze six standards, environmental standards (1648a and 1649b), and samples collected in urban environments in Guangzhou in the Pearl River Delta region, which serve as valuable reference points for evaluating the organic composition of the atmospheric environment. The results indicate a high degree of accuracy in the analytical method. Sodium octyl-d17 sulfate serves as the internal standard, with a linear correlation coefficient of the six standards, boasting a linear correlation coefficient r ranging from 0.993–0.9991 and a slope, k, of the linear equation from 0.966–1.882. The instrument detection limits (IDLs) are established at 0.03–0.20 µg mL−1, while the method detection limits (MDLs) fall within the range of 0.30–1.75 ng m−3, demonstrating the method's exceptional sensitivity. Since isoprene-derived organosulfates (iOSs) are highly polar due to containing a hydrophilic bond to the hydroxyl group and a hydrophobic bond to the sulfate, and as such showed strong retention using this method, this technique employs sodium ethyl sulfate and sodium octyl sulfate standards for semi-quantitative compound analysis of iOSs. The error in sample analysis (EA) ranged from 12.25 %–95.26 %, and the two standards maintained a consistent recovery rate between 116 %–131 % and 86.4 %–127 %. These findings indicate a high level of precision when semi-quantifying compounds with similar structural characteristics, affirming the analysis method's minimal relative error and underscoring its repeatability, process stability, and the reliability of its results for iOSs. To enhance the method's reliability assessment, the study analyzed polar organic components of standard particulate matter samples (1648a and 1649b), providing precise determinations of several iOSs using this method. Methyltetrol sulfate (m/z 215, C5H11SO7-) is the highest concentration in the ambient samples, up to 67.3 ng m−3 in the daytime. These results serve as valuable reference points for assessing the organic composition of the atmospheric environment.
Cold Climates, Complex Hydrology: Can A Land Surface Model Accurately Simulate Deep Percolation?

Published: May 2024

Abstract. Cold regions present unique challenges for land surface models simulating deep percolation or potential groundwater recharge. Previous model evaluation efforts often overlooked these regions and did not account for various sources of uncertainties influencing model performance and its evaluation. This work addresses these limitations using high-resolution integrated lysimeter measurements to assess the performance of the SVS land surface model in a cold climate. SVS showed promise in the simulation of snowmelt and rainfall-driven deep percolation events. It also simulated daily snow depth well, with a correlation coefficient (r) greater than 0.94 and a mean-bias-error (MBE) smaller than 3.0 cm for most of the simulation period. The newly implemented soil-freezing scheme reasonably simulated the near-surface soil temperature (r = 0.89) with a slight cold bias (MBE = -0.8 °C). However, the model's inability to represent frozen soil infiltration and preferential flow resulted in a significant underestimation of percolation (r: 0.35, MBE: -0.8 mm·day-1) and near-surface soil moisture during cold months (MBE: -0.058 m3 ·m-3). Those findings highlight the importance of a comprehensive model evaluation for improving deep percolation modeling in cold regions. Such improvements can lead to more informed decision-making regarding groundwater resource management in a changing climate.

Abstract. Understanding the compositions and evolution of atmospheric organic vapors is crucial for exploring their impact on air quality. However, the molecular and seasonal characteristics of organic vapors in urban areas, with complex anthropogenic emissions and high variability, remain inadequately understood. In this study, we conducted measurements in urban Beijing during 2021–2022 covering four seasons using a Vocus-PTR, an improved Proton Transfer Reaction-Mass Spectrometry (PTR-MS). During the measurement period, a total of 895 peaks are observed, and 543 of them can be assigned to formulas. The contribution of CxHyOz species is most significant, which compose up to 53.7 % of the number and 76.0 % of the mass of total organics. With enhanced sensitivity and mass resolution, various sub-ppt level species and organics with multiple oxygens (≥3) were discovered. When counting the species number, 42.2 % of the organics measured are at sub-ppt level and 37.8 % of the species contain 3–8 oxygens. Organic vapors with multiple oxygens mainly consist of intermediate volatility and semi-volatile compounds, and many of them are found to be the multi-generational oxidation products of various volatile organic precursors. In summer, the fast photooxidation process generates organic vapors with multiple oxygens, and leads to an increase in both their concentration and proportion. While in other seasons, the variations of organic vapors with multiple oxygens are closely correlated with those of organic vapors with 1–2 oxygens, which could be heavily influenced by primary emissions. Organic vapors with low oxygen content (≤ 2 oxygens) are comparable to the results obtained by traditional PTR-MS measurements in both urban Beijing and neighboring regions.
Consistency-Checking 3D Geological Models
Authors: Parquer Marion N. , de Kemp Eric A. , Brodaric Boyan , Hillier Michael J.
Published: May 2024

Abstract. 3D geological modelling algorithms can generate multiple models that fit various mathematical and geometrical constraints. The results, however, are often meaningless to geological experts if the models do not respect accepted geological principles. This is problematic given the expected use of the models for various downstream purposes, such as hazard risk assessment, flow characterization, reservoir estimation, natural storage, or mineral and energy exploration. Verification of the geological reasonableness of such models is therefore important: if implausible models can be identified and eliminated, it will save countless hours, computational and human resources, as well as minimize user problems. To begin assessing geological reasonableness, we develop a framework for consistency-checking and test it with a proof-of-concept tool. The framework consists of a space of consistent and inconsistent geological situations that can be held between a pair of geological objects, and the tool assesses a model against the space to identify (in)consistent situations. Both the framework and tool are successfully applied to several case studies as a promising first step toward automated assessment of geological reasonableness.

Abstract. Accurate representation of the hourly variation of the NO2 column-to-surface relationship is needed to interpret geostationary constellation observations of tropospheric NO2 columns. Prior work has revealed inconsistency in the hourly variation in NO2 columns and surface concentrations. In this study, we use the high-performance configuration of the GEOS-Chem model (GCHP) to interpret the daytime hourly variation in NO2 total columns and surface concentrations during summer. We use summer-time Pandora sun photometers and aircraft measurements during the Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality (DISCOVER-AQ) field campaign over Maryland, Texas, and Colorado as well as 50 sites (31: contiguous USA, 10: Europe, 9: Asia) from the Pandonia Global Network (PGN). We correct the Pandora columns for 1) hourly variation in the column effective temperature driven by the fractional boundary layer contribution to the total column, and 2) change in local solar time along the line-of-sight of the Pandora instrument. The corrected Pandora observations are increased by about 5–6 × 1014 molecules cm-2 at 9 AM and 6 PM across all Pandora sites. We conduct fine resolution (~12 km) simulations over the contiguous US, Europe, and East Asia using the stretched grid capability of GCHP. We also examine the effect of planetary boundary layer height (PBLH) corrections on the total columns. We first evaluate the GCHP simulated absolute NO2 concentration with Pandora and aircraft observations. We find that fine resolution simulations at 12 km compared with moderate resolution ~55 km reduce the Normalized Bias (NB) versus Pandora total columns (19 % to 10 %) and versus aircraft measurements (25 % to 13 %) over Maryland, Texas, and Colorado. Fine resolution simulations at 12 km compared with moderate resolution at 55 km reduce the NB versus Pandora total columns over the eastern US (17 % to 9 %), western US (22 % to 14 %), Europe (24 % to 15 %), and Asia (29 % to 21 %). We next use the 12 km simulation to examine the hourly variation in the NO2 column and surface concentrations. We explain the weaker hourly variation in NO2 columns than at the surface as a function of 1) hourly variation in the column effective temperature, 2) hourly variation in the local solar time along the Pandora line-of-sight and 3) the integral of weakly connected layers; with the lowest 500 m exhibiting greater NO2 concentrations in morning and evening than midday, while the residual column above 500 m dominates the total column with weaker variability.

Abstract. Weather forecasts at subseasonal-to-seasonal (S2S) timescales have little or no forecast skill in the troposphere: individual ensemble members are uncorrelated and span a range of atmospheric evolutions that are possible for the given set of external forcings. The uncertainty of such a probabilistic forecast is then determined by this range of possible evolutions – often quantified in terms of ensemble spread. Various dynamical processes can affect the ensemble spread within a given region, including extreme events simulated in individual members. For surface pressure or geopotential height forecasts over Europe, such extremes are mainly comprised of synoptic storms propagating along the North Atlantic storm track. We use ECMWF re-forecasts from the S2S database to investigate the connection between different storm characteristics and ensemble spread in more detail. We find that the presence of storms in individual ensemble members at S2S time scales contributes about 20 % to the total geopotential height forecast uncertainty over Northern Europe. Furthermore, certain atmospheric conditions associated with substantial anomalies in the North Atlantic storm track show reduced geopotential height ensemble spread over Northern Europe. For example, during periods with a weak stratospheric polar vortex, the genesis frequency of Euro-Atlantic storms is reduced and their tracks move equatorwards. As a result, we find weaker storm magnitudes and lower storm counts, and hence anomalously low subseasonal ensemble spread, over Northern Europe.

Abstract. The non-linear interactions between an internal wave field propagating through a balanced turbulent flow make the incoherent propagation of ocean internal tides difficult to understand and to predict. In this paper, we propose a data-driven method that extracts the structures of a wave field correlated with the fluctuations of the background flow, exploiting the fact that the scattering of the wave results from a quadratic nonlinearity involving both types of motions. The method consists of applying the extended proper orthogonal decomposition method to the complex wave envelope, extracted by complex demodulation, in order to provide the spatial structures of an incoherent wave contribution correlated to the proper orthogonal decomposition modes of the balanced motion. Using the rotating shallow water as a canonical model for wave / balanced flow interactions, we describe the connection between the variability of the jet and the incoherence of the internal wave, which provides some theoretical foundations to the proposed method. This expected connection is then confirmed by numerical simulations of the rotating shallow water model, and the variability modes of the jet and wave field are analysed. Finally, an algorithm for estimating the jet component and the associated wave field from single snapshots of the sea level height is proposed and tested using outputs from numerical simulations. We show that such algorithm provides a valuable coupled estimate of the two dynamics, especially in configurations where the wave signal is small compared to the jet.

Background: Academic libraries play a significant role in the student learning process. However, student needs and preferences as well as new paradigms of learning are driving libraries to transition from quiet book repositories to places of collaboration and open information. This descriptive, mixed methods case presentation explores the transition of one library, the United States Air Force School of Aerospace Medicine Franzello Aeromedical Library, in three key areas: collection, capability, and facility. Due to the niche subject matter and audience the library serves, this case also describes how the Franzello Aeromedical Library’s distinct collection and capability remained intact throughout modernization.
Case Presentation: The Franzello Aeromedical Library’s modernization project aimed to augment the library as a cutting-edge resource supporting USAFSAM's education, consultation, and research mission to equip Aerospace Medicine Airmen with the skills and knowledge for healthcare delivery in austere environments. This project was approached using five phases: 1) best practices baseline, 2) baseline evaluation of library visitor needs, 3) collection weeding, 4) capability, and 5) space design and construction.
Conclusion: As a result of this complex two-year project, several recommendations were gleaned. Use the effort as an opportunity to market library services to new audiences. Ensure all stakeholders are at the table from day one and in perpetuity to save time, and consider using purposeful decision-making models, such as Courses of Action, to make tough calls. Be prepared for delays by padding your timeline and compromise where necessary to keep the project alive. Finally, the authors recommend using in-project discovery and findings to plan for future need justification.

Modernization movements which has begun 17.century in Europe, brought to changes and transformation on politics, law, education, art and arthitectural. The phenomenon of modernization which still continues today, has allowed to create own ideology every process. Using modernization effects on arthitectural, states will defined own ideology. Modernization ideologies reflected city centers in Turkey like same in West. It was seen with modernization phenomenon in Ottoman Empire’s Reform Era first time. Modern ideologies was showed in structures which was made in Istanbul city. When transforming nation state, Ankara was choosed capital in line with nationalist modern ideology. Ankara has became a “tabula rasa” for the ideology that was intended to be reflected. Thus modern ideology has found a chance to was to be reflected. Because republic is a modernizing revolution.

Lavirint pravne kvalifikacije oružanih sukoba u Hrvatskoj 1990. - 1995.
Authors: Hrnjaz Miloš
Published: May 2024

Gotovo trideset godina nakon oružanih sukoba u Hrvatskoj, i dalje traju rasprave o njihovim uzrocima, pravnoj prirodi i posledicama koje imaju po današnje odnose Srbije i Hrvatske, ali i odnose u samoj Hrvatskoj između Srba i Hrvata. U ovom radu se traga za odgovorom na pitanje pravne kvalifikacije tih oružanih sukoba i može li nam ona ponuditi određene pravce za početak unapređivanja savremenih odnosa Hrvatske i Srbije. Osnovni argument je da se pravna kvalifikacija oružanih sukoba u Hrvatskoj menjala i da je od nemeđunarodnog oružanog sukoba u leto 1991. godine on kasnije evoluirao u međunarodni. Osim toga, u radu se tvrdi i da ispravno sagledavanje pravne kvalifikacije tih sukoba nudi određena polazišta za unapređenje savremenih odnosa Srbije i Hrvatske, ali i da ta pravna kvalifikacija ima inherentna ograničenja u pogledu šireg konteksta političkih odnosa tih dveju država.
