Impact of International Diplomacy on Combating Global Terrorism
Authors: Nwala Paul
Published: January 2024

Insecurity had defined the global arena with insurgency and terrorism increasing by leaps and bounds. Therefore, defining terrorism as a discrete international crime under the purview of international law normatively recognizes and protects vital international community values and interests. The issue of terrorism symbolically expresses community condemnation, and stigmatizes offenders. In proper analysis context the paper opines that any definition of terrorism also accommodates reasonable claims to political violence, particularly against repressive governments, and this paper examines the range of exceptions, justifications, excuses, defenses, and amnesties potentially available to terrorists, as well as purported exceptions such as self-determination struggles. The paper further seeks to minimize recourse to violence, it recognizes that international law should not become complicit in oppression by criminalizing legitimate forms of political resistance and instead diplomacy can be applied in such scenario. In the absence of an international generally accepted definition of terrorism, the paper explores how the international community has responded to terrorism in international and ‘regional’ treaties, the United Nations system, and in customary law which has proof that diplomacy is a vital instrument in the global combat of terrorism. The conclusion of the paper explores the distinctiveprohibitions and crime of ‘terrorism’ in armed conflict under international humanitarian law.

Epithelioid sarcoma is a rare aggressive soft tissue sarcoma, which can be distal or proximal types. The classic form (distal-type) of epithelioid sarcoma mainly occurs in teenagers and young adults. A rarer form, called large-cell (proximal-type) epithelioid sarcoma, tends to be more aggressive and mainly affects adults. The proximal subtype mostly arises from the proximal pelvis, limbs, and genital tract. We report a case of a 59 -year-old female, presented with a progressively growing mass in the left labia majora. Gynecologic examination revealed a 2 cm mobile and painless mass that was not attached to deep planes. The histological study showed a multinodular tumor was seen comprising sheets of oval to polygonal cells with moderate amount of cytoplasm. Interspersed were larger, rhabdoid cells with abundant eosinophilic cytoplasm and prominent nucleoli. On IHC, the tumor cells showed positivity for EMA and CKAE1/AE3 and do not expressed INI-1 in the nucleus. All tumor cells were negative for S-100 protein and CD34. The histopathological diagnosis was soft tissue of the vulvar region with proximal epithelioid sarcoma. The patient received adjuvant external pelvic radiotherapy and brachytherapy in the vulvar bed. Currently, 3 years after diagnosis, the patient does not present signs of tumor recurrence in her controls. Due to its low incidence, there are no evidence-based diagnostic algorithms or published recommendations for treatment. The prognosis is generally poor. A wide excision with clear margins is imperative with options of post-operative CT/RT in individual cases during a close follow-upbehavior, as seen in our case.

Explore the Impact of Initial Data Coherence on ARIMA Model Prediction Based on Python
Authors: Yan Yuting
Published: January 2024

As the most intuitive economic indicator reflecting the economic development level of a company, an industry, or even a country, the fluctuation of stock prices will attract great attention. In order to avoid the loss of investors to a certain extent, stock price prediction is widely used in the stock market to prevent risks to a certain extent, and the ARIMA model is a time series prediction model that has been widely used in recent years. Therefore, the application of the ARIMA model to stock price forecasting is the main research object of this paper. This paper speculated at the beginning of the study that there may be a close relationship between the degree of fit of the ARIMA model and the consistency of the prediction results with the original data used. However, the existing literature is basically blank in this aspect of research and analysis. Therefore, this paper chooses to conduct comparative experiments on a set of continuous data and a set of discontinuous data to analyze the influence of the consistency of the original data under application conditions on the ARIMA model fitting and prediction results, hoping to fill the gaps in the existing literature through this research. The experimental results show that in some cases of original data with obvious discontinuous data missing, its smoothness is extremely poor, resulting in a poor fitting effect of the ARIMA model, and it can not be applied to the prediction of such data.

Authors: Huang Yaobin
Published: January 2024

The evolution of International Financial Reporting Standards (IFRS) reflects the needs of the global business environment and the pursuit of higher quality financial reporting. This paper discusses and explores major changes implemented in IFRS, specifically in the areas of revenue recognition, lease accounting, and the treatment of intangible assets. The shortcomings of the past application of IFRS standards in these aspects are presented in this paper, as well as changes and benefits after IFRS made corresponding modifications. By reviewing materials and literature, the study conducts a comparison between IFRS and the United States Generally Accepted Accounting Principles (US GAAP). These two major accounting frameworks have adopted unique methods and standards. Still, both the International Accounting Standards Board (IASB) and the Financial Accounting Standards Board (FASB) work hard together to realize international harmonization. The outcomes of this research make it clear that ongoing refinements to IFRS have significantly improved the clarity, consistency, and comparability in how financial activities are reported. Such changes have been pivotal in diminishing uncertainties and bolstering the trustworthiness of financial disclosures. Being influenced by the continuous developments in IFRS, greater transparency and accountability in financial reporting will be achieved. This has made a great contribution to helping investors in sound economic decision-making and enhancing investor confidence.

Исследованы особенности дифракции рентгеновского пучка от пьезокристаллов бифталатов калия и рубидия при условии возбуждения в них поперечных ультразвуковых колебаний. Ранее при аналогичном воздействии в кристаллах кварца нами наблюдался эффект рентгеноакустического перераспределения, при котором существенно увеличивается интенсивность дифрагированного излучения в точном брэгговском положении при одновременном уменьшении интенсивности прошедшего пучка, вплоть до зануления при определенных параметрах воздействия для отражающих атомных плоскостей (101/1), получившего название полной переброски. Этот эффект можно использовать для управляемой перестройки интенсивности дифрагированного пучка. С целью поиска новых материалов для изготовления элементов, позволяющих осуществлять такую пе-рестройку, в данной работе изучены зависимости степени усиления дифрагированного излучения от амплитуды управляющего сигнала для кристаллов бифталатов калия и рубидия (БФР). Продемонстрирована фактическая возможность модуляции интенсивности рентгеновского излучения с помощью поперечных колебаний в этих кристаллах.
Peculiarities of X–ray beam diffraction from potassium and rubidium biphthalate piezocrystals under the condition of excitation of transverse ultrasonic vibrations are investigated. Previously, under a similar influence in quartz crystals, the effect of X–ray acoustic redistribution was observed, in which the intensity of diffracted radiation in the exact Bragg position increases significantly with a simultaneous decrease in the intensity of the transmitted beam, down to zero for certain parameters for reflecting atomic planes (101 ̅1), called the full pumping effect. This effect can be used for controlled tuning of the diffracted beam intensity. In this work, in order to search for new materials for the creation of elements that allow such a rearrangement, we studied the dependences of the degree of amplification of diffracted radiation on the amplitude of the control signal for potassium and rubidium biphthalates crystals. The actual possibility of X–ray intensity modulation using transverse vibrations in these crystals is demonstrated.

Исследованы структурные и оптические свойства тандемных структур кремний/перовскит с иерархической антиотражающей поверхностью на границе раздела. Поверхность состояла из микроразмерных пирамид и наноразмерных коротких игл, образованных соответственно методами химического и реактивного ионного травления кремниевых подложек. Показано, что пленка перовскита без пор и пустот с высокой степенью конформности покрывает иерархическую поверхность. Изготовленные образцы характеризуются низким коэффициентом отражения в широком диапазоне длин волн излучения.
The structural and optical properties of tandem silicon/perovskite structures with a hierarchical antireflective surface at the interface have been studied. The surface consisted of micro-sized pyramids and nano-sized short needles, formed respectively by chemical and reactive ion etching of silicon substrates. It is shown that a perovskite film without pores and voids covers a hierarchical surface with high conformity. The manufactured samples are characterized by low reflectance over a wide range of radiation wavelengths.

Исследовано взаимодействие пищевого консерванта и красителя эритрозина В с бычьим сывороточным альбумином (БСА) под воздействием электромагнитных волн миллиметрового диапазона (ММ ЭМВ) с частотами 41.8 и 51.8 ГГц методом УФ-денатурации, а также спектроскопическими (поглощение, флуоресценция, круговой дихроизм (КД)) методами. Показано, что облучение ММ ЭМВ частотой 51.8 ГГц приводит к стабилизации комплекса БСА-эритрозин В. В то же время, параметры денатурации комплекса при облучении раствора БСА с частотой 41.8 ГГц, в пределах ошибки, не отличаются от таковых, полученных для необлученных образцов. Показано также, что под влиянием облучения частотой 51.8 ГГц, изменения конформации БСА не обнаруживается, в то время как в случае комплекса БСА-эритрозин В имеет место изменение конформации. При этом процесс комплексообразования является термодинамически выгодным и под влиянием ММ ЭМВ реализуется за счет дополнительных водородных связей и вандерваальсовых взаимодействий между БСА и эритрозином В.
The interaction of food conservator and dye erythrosine B with bovine serum albumin (BSA) under the effect of millimeter range electromagnetic waves (MM EMW) with frequencies 41.8 and 51.8 GHz has been studied by the UV-denaturation and spectroscopic (absorption, fluorescence, CD) methods. It was shown that the irradiation by MM EMW with the frequency 51.8 GHz results in stabilization of the complex BSA-erythrosine B. At the same time, denaturation parameters of the complex at the irradiation of BSA solution with the frequency 41.8 GHz, in error framework, do not differ from those, obtained for non-irradiated samples. It was also revealed that under the effect of the irradiation by 51.8 GHz frequency there is no conformational change of BSA, while in the case of the complex BSA-erythrosine B a change of the protein conformation takes place. Though, the complex-formation process is thermodynamically beneficial and implemented due to the additional hydrogen bonds and vander- Waals interaction between BSA and erythrosine B under the effect of MM EMW.
Essays on Risk Creation in the Banking Sector
Authors:   , Kütük Samet
Published: January 2024

This thesis consists of four essays exploring risk creation in the banking sector. The essays examine how conflicting interests can compromise the objectivity, judgment, and decision making of economic agents. Consequently, they may prioritize their personal or institutional interests over the best interests of others or the entire financial system.

Chapter 2 delves into the conflict of interest that arises when a bank serves as an investor in the stock market. Chapter 3 revisits the discussion of the potential misalignment between sovereign incentives and the collective interests of the currency union, particularly in the bond market. Chapter 4 draws attention to a situation where regulations in the banking sector may be advantageous for a government in the sovereign bond market. Finally, Chapter 5 looks at the flip side of the coin, examining how banks may be susceptible to moral hazard concerns in their FX lending decisions, given that they do not fully bear the consequences of their actions.
The freedom of movement of asylum-seekers within the host State under international and European human rights law
Authors:   , Ruiz Ramos Juan Jose
Published: January 2024

Asylum-seekers in several European States often have to endure policies that make them feel trapped in a specific part of the country or that constrain their movements to such an extent that their situation resembles detention. How can human rights law respond to these practices? This PhD thesis comprehensively examines the right to free movement within the country under international and European human rights law, as well as under the Spanish and German domestic legal systems. With a specific focus on asylum-seekers, the study analyses this issue from four different angles: (1) the travaux préparatoires of the various instruments that enshrine this freedom; (2) the personal scope of the right according to legal doctrine and case law; (3) the material scope of the right, i.e. the distinction between a restriction on movement and a deprivation of liberty; and (4) the safeguards offered by this right. By comparing the protection afforded to asylum-seekers with that extended to nationals and individuals in general, the thesis contributes to the growing literature on migration exceptionalism. Additionally, the exploration of the legal status of asylum-seekers under various treaties and the detailed assessment of the definition of ‘detention’ hold the potential to inform research in other areas of human rights law, including refugee law.
Changing landscapes of Apulia
Authors:   , Ducci Marta
Published: January 2024

Rural landscapes are a fundamental part of the European territory and are generally recognised for their specific ecological, economic and cultural qualities. Great importance is attached to identifying new strategies for protecting, conserving and developing these landscapes, which are often characterised by the coexistence of a fragile balance between natural resources, agricultural traditions and small urban settlements.
Citizen participation is among the most pressing demands in the international debate on heritage and landscape. Although documents such as the European Landscape Convention (ELC) promote the engagement of locals in defining landscape heritage values and identifying strategies for its protection, management and planning, observance of these principles is not widespread in practice.
The aim of this thesis was to develop and evaluate a methodology that makes it possible to uncover local heritage perceptions and integrate them into a planning strategy in order to implement the ELC principles and foster widespread participation in the landscape planning practice. To this end, PPGIS and geo-design methods were combined to engage the Brindisi Plain community in Apulia (Italy) as a case study. Citizens, stakeholders and experts from different fields were involved through map-based online questionnaires and co-design workshops, allowing them to actively participate in defining and planning the local cultural landscape.
Through this study, the developed methodology proved to be an effective way to implement the European Landscape Convention principles by facilitating participation and the involvement of the local population in the definition and planning of cultural landscapes. The three-step approach allowed us to uncover local heritage perceptions of the Brindisi Plain community and integrate them into a shared planning strategy. Combining citizen and expert knowledge produced a multivocal representation of heritage values, which could then be translated into design proposals. The use of GIS-based tools facilitated community engagement in landscape planning in rural contexts, enabling citizens to co-design their future cultural landscapes.
