Vertically probabilistic selling mechanism under asymmetric quality-tier competition: An analytical
exploration
Authors: Yang Guang , TIAN Lin 
Published: February 2024

Abstract
Compared with the existing literature that focuses on horizontal features of probabilistic selling (PS), PS in vertical quality markets is receiving significant attention in the travel and marketing industries, both in the United States and China. Focusing on a general framework for a vertically PS mechanism that involves firm asymmetric quality-tier competition and the active role of an intermediary retailer, we consider a duopoly, where the leader firm can endogenously generate differentiated quality PS products via either the direct channel or the indirect channel through an intermediary retailer, while the follower firm sells transparent products by providing exogenously differentiated quality levels. Utilizing Stackelberg game theory, we construct an economic model involving PS under asymmetric competition by quantifying probabilistic products in terms of expected quality and provide firms with profit-maximizing strategies under three scenarios. Second, we theoretically analyze three strategies to identify the advantages of PS, and further conduct a comparison of PS and traditional selling (TS) in terms of revenue pricing, social welfare and consumer surplus.Our results suggest that (i.) PS is not always profitable; only if the expected quality level is low could PS be effective; (ii.) PS could weaken asymmetric quality-tier competition and further mitigate cannibalization effect. In our duopoly model, if there were no probabilistic sales, the equilibrium would eventually converge to a situation where one Firm produces a high-quality product and the other produces a relatively low-quality product. Finally, we extend our model by incorporating attitude to risk and word-of-mouth persuasion. These additions enhance the applicability of our conclusions.

This study aims to describe the conceptual understanding of two-dimensional shapes in students with special needs based on Pirie Kieren's theory in terms of learning motivation. This research is a case study with the research subject is 1 students with special needs of class IV at SDN Pademawu Timur V The results of this study are low learning motivation with layers of understanding on the square starting from Image making then head to property noticing to ineffective folding back to image making and do ineffective folding back again to primitive knowing. In solving the square problem, the subject doubled back to ineffective image-making and primitive knowing. Meanwhile, in the rectangular problem, the subject does one folding back to image making. There are similarities in solving square and rectangular problems, for example, the subject describes the two-dimensional shape first before image making and folding back because they don't know how to calculate the area of a square and rectangle. From the similarities and differences in the thinking flow of students with special needs in squares and rectangles, educators are expected to be able to pay attention to their understanding abilities and learning motivation before carrying out learning.

Published: February 2024

The thermohaline processes in the Arctic coastal zone of seas in Russia are analyzed on the example of some parts of the Barents and Kara Seas: specifically, the Medynsko-Varandey site and the near-mouth coast of the Ob and Yenisey. For comparison with the thermohaline characteristics of international waters, the authors used observation data obtained by Admiral Vladimirsky oceanographic research ship in the summer — autumn of 2014 and Professor Multanovsky in the summer — autumn of 2019 (“Transarctica 2019”). The study aims to obtain typical and extreme distributions of hydrological characteristics in order to estimate heat and salt fluxes in the bottom layers. The characteristic substance fluxes can be used in the calculations of fluxes in bottom sediments, which have a significant effect on permafrost thawing. Such sedimentary rocks constitute a new source of minerals in the Arctic zone. In order to calculate heat and salt fluxes, it is necessary to obtain high spatial resolution data. The available data may be insufficient, thus requiring integrated oceanological observations in the coastal zone.
UM LUTO QUE DANÇA: O FESTEJAR LÉSBICO E NEGRO EM MEMÓRIA A LUANA BARBOSA
Authors: Freire Isadora Façanha Gurgel 
Published: February 2024

O artigo a seguir se orienta a partir da dissertação da autora acerca das consequências morais, simbólicas e afetivas após um episódio criminoso de violência policial que ficou conhecido como Caso Luana Barbosa, ocorrido em 2016, no estado de São Paulo. Enquanto à dissertação coube analisar materiais discursivos constituintes de versões que abrangiam a ocorrência por parte da defesa e da acusação, o trabalho a seguir traz a análise sobre um fenômeno que marcou e continua, insistentemente, a singularizar o processo de luto e de reconhecimento da vítima enquanto uma bandeira do maior movimento lésbico de São Paulo: o acontecimento da festa Sarrada no Brejo. A festa, em si, trata-se de uma realização originalmente centrada no encontro de ativistas lésbicas e periféricas em homenagem à Luana Barbosa, no entanto, por meio de deslocamentos de relações de sentido entre as participantes entorno do luto, promove a produção de um novo território para pensar e viver erotismos lésbicos, pretos e periféricos – sempre em estado de alerta. Ao observar as adjacências do funk e do pagode, os dois gêneros musicais que fluem e garantem o evento e suas condutas, analiso de que forma a performance sensual e os conjuntos de práticas envolvidas na festa Sarrada no Brejo redefinem estereótipos e recolocam a pessoa de Luana Barbosa como uma existência de vida e de gozo, e não só mais uma vítima da violência policial e opressão racista paulistana.

Hacia una Reforma Fiscal para el crecimiento y la igualdad
Authors: Casar Pérez José Ignacio 
Published: February 2024

Este libro presenta un diagnóstico general de la carga fiscal agregada en México y de su composición; una evaluación de sus efectos en la distribución del ingreso y una reflexión, sobre las consecuencias de la penuria fiscal del Estado desde la Gran Recesión de 2008 – 2009 que ha llevado a la contracción sistemática de la inversión pública en el marco de un esquema de política fiscal que, si bien ha permitido mantener el equilibrio macroeconómico en lo que va del siglo, lo ha hecho a costa de sacrificar la inversión pública y, en consecuencia, de limitar el potencial de crecimiento del país, lo que a su vez ha frenado el crecimiento de los ingresos públicos en un círculo vicioso que es necesario revertir. Asimismo, presenta las opciones disponibles para la construcción de una propuesta de reforma del régimen fiscal que fortalezca los ingresos del Estado, lo coloque en una mejor posición para enfrentar la posible recesión internacional, promueva el crecimiento a largo plazo y contribuya a una mejor distribución del ingreso y al abatimiento de la pobreza.
Reducing wind energy forecast error with a hybrid ensemble prediction methodology
Authors: Rutherford Justin , Nyhan Marguerite , Leahy Paul 
Published: February 2024

As a commodity, wind energy is typically traded in ex-ante time frames
and is dependent on forecasts to secure physical positions up to 36
hours after gate closure for trading in Day-Ahead markets. Wind energy
is traded in discrete quantities, however it is generated from an
intermittent and variable resource. Deterministic forecasts are
preferred for energy trading as the most compatible solution to provide
a defined forecast quantity. However, deterministic forecasts cannot
capture the stochastic nature of the underlying power source and are
therefore sub-optimal. Ensemble based forecasts have the potential to
reduce forecast error by accounting for uncertainties not captured in
deterministic models. However, ensemble forecasts are not always
available at the vertical levels at which wind turbines operate.
Therefore, a method is needed to apply ensemble information to turbine
hub heights for energy forecasting purposes. This paper presents a novel
machine learning based method that translates the perturbations from a
localised Numerical Weather Prediction model’s 10m wind speed component
to an ensemble energy forecast at 100m. The extrapolated ensemble based
forecast has improved the forecast accuracy by 9% when compared to the
deterministic output. The findings will have important implications for
future energy trading, transmission system operation and meteorological
forecasting.

Constitutional and legal principles of ensuring the independence of judges of the Constitutional Court of Ukraine
Authors: Berch V. V. , Byelov D. M. , Bysaga Yu. M. 
Published: February 2024

The independence of judges constitutes one of the fundamental components of the legal system in any democratic country. Within the legal framework of Ukraine, the constitutional and legal principles guaranteeing the independence of judges, specifically those of the Constitutional Court, represent a key element of the legal structure ensuring the stability of the rule of law, the protection of human rights, and the development of the rule-of-law state.
It is emphasized that the guarantees of the independence of courts of general jurisdiction and bodies of constitutional justice play a critical role in ensuring legal stability and protecting judges from political or external influences. The independence of judges in performing their functions is crucial in upholding the principles of the rule of law and justice. Therefore, it is vital to ensure an effective mechanism to safeguard this independence from any external pressure or influence, regardless of the sphere of jurisdiction.
It has been identified that one potential drawback associated with expressing a separate opinion of a judge of the Constitutional Court could be the blurring of the clarity of the adopted decision. Separate opinions generate significant interest among scholars and practicing lawyers, with the texts of such opinions often utilized in the educational process of legal institutions and drawing attention from judges of the Constitutional Court of Ukraine during the consideration of similar cases. As these documents contain doctrinal views on various aspects of cases reviewed by the Constitutional Court of Ukraine, they become the subject of additional analysis and consideration.
It is noted that ensuring the independence of judges of the Constitutional Court of Ukraine is based on a comprehensive system of constitutional and legal guarantees aimed at ensuring their independence in resolving important constitutional issues and preserving the principles of the rule-of-law state in Ukraine.
Moreover, Ukraine, as a participant in international treaties and organizations, is obliged to adhere to international standards in the field of justice and guaranteeing judicial independence. Consequently, means of protecting the rights of judges of the Constitutional Court are developed and adapted to international normative documents.
The concept and classification of principles of constitutional-legal responsibility of subjects of the electoral process
Authors: Vyshnevska M. M. 
Published: February 2024

In this scientific article, the concept and classification of the principles of constitutional-legal responsibility of subjects of the electoral process are examined and analyzed. It is established that elections are a phenomenon guided by central principles of democracy. They provide citizens with the opportunity to choose their representatives and determine the future of the country. However, to ensure the fairness and legality of the electoral process, it is essential to have an effective system of constitutional-legal responsibility for the subjects of the electoral process.
Fundamental (basic) principles of constitutional-legal responsibility of subjects of the electoral process include legitimacy and legality, honesty and transparency, justice, accountability and punishment, independence of the electoral commission, freedom of speech and media independence, international observation, as well as the principle of popular sovereignty.
It is emphasized that the principle of justice is fundamental to ensuring the democracy and legitimacy of the electoral process. It helps ensure that all participants have equal conditions for expressing their political preferences and freely expressing the will of the citizens through voting. Constitutional-legal responsibility also includes a prohibition of discrimination and ensuring equal opportunities for all subjects of the electoral process.
Highlighting the principle of independence of the electoral commission, it is crucial for ensuring fairness and trust in the electoral process. The electoral administration should be entirely apolitical, meaning that electoral bodies and commissions should not be influenced by any political party or candidate. They should operate independently of political ambitions and interests, strictly adhering to the laws and constitutional norms of the country. Their actions and decisions should be based on the law rather than political or personal beliefs.
In summary, the principles of constitutional-legal responsibility of subjects of the electoral process are guiding ideas and fundamental principles enshrined in the Constitution and laws of Ukraine, defining the content and essence of the constitutional-legal responsibility of participants in the electoral process, the peculiarities of the development of its normative-legal regulation, and the specifics of its application.
Dimensions of the constitution
Authors: Pustovalova I. S. 
Published: February 2024

The article is devoted to the conceptualization of the dimensions of the constitution as an important direction of modern political and legal research. It was noted that the category “dimension” combines the objective determination of the influence of the constitution on the course of social relations with its utilitarian value.
Given the complexity and multidimensionality of society, it can be argued that there can be many dimensions of the constitution. However, it is known that the constitution to one degree or another regulates (consolidates) all four subsystems of the social system: political, economic, social, and spiritual and cultural. Therefore, the most general, system-creating dimensions of the constitution can be only four - according to the number of subsystems of the social system. All of them can be covered by the term “general or general social dimensions”.
The author claims that from a legal point of view, we should be primarily interested in those “internal” dimensions of the constitution that characterize the significance of the constitution for the state mechanism and the national legal system. They, again conditionally, can be called “special” or “legal”. The relevant criteria should be sufficiently universal and significant, capable of being applied to states of different levels of development and different historical eras. At the same time, it should be understood that the constitution is only a legal instrument, so it can neither be blamed for a bad political choice nor praised for a good one.
In the broadest plan, five main legal criteria for the success of the constitution are proposed – these are its endurance (permanence), legitimacy, the ability to resolve political conflicts in a legal way, the ability to limit agency costs, as well as to promote the production of public goods.
The opinion that according to the vast majority of the dimensions listed above, the current Constitution of Ukraine of 1996 demonstrates quite high results, being an example of a modern and effective Basic Law, is justified. The main problem facing the national Constitution in this regard is the problem of limiting the so-called “agency costs”, especially in the area of corruption prevention.
The prosecutor’s influence on compliance with the principle of equality of parties in civil proceedings
Authors: Hlushkov V. O. 
Published: February 2024

Despite the reform of the prosecutor’s office carried out in the period from 2014 to 2016, one of the main ideas of which was the maximum concentration of the prosecutor’s office on activities within the criminal process excluding the so-called “general supervision”, every year, the courts of Ukraine consider more and more civil cases cases initiated by the prosecutor acting in accordance with Art. 23 of the Law of Ukraine “On the Prosecutor’s Office” No. 1697-VII dated October 14, 2014.
This circumstance definitely calls into question the effectiveness of the reform and creates the need to analyze its results. Also, it is considered appropriate to check whether the current legislation of Ukraine defines the range of interests of the state that the prosecutor’s office has the right to defend in court, whether there is no place for the prosecutor to abuse his right to represent the interests of the state in civil proceedings, as well as whether the participation of the prosecutor affects compliance with the principle equality of all participants in the civil process before the law and the court, which is one of the basic principles of civil justice, defined as part 3 of Article 2 of the Civil Procedure Code of Ukraine and Article 129 of the Basic Law of Ukraine.
This article also publicizes the author’s position regarding the existence of a problem in the fact that the prosecutor’s office is empowered to initiate legal proceedings on virtually any issue that, to one degree or another, is of importance to the state.In addition, the main ideas and goals that were pursued and declared by the legislator during the reform of the prosecutor’s office were highlighted, judicial practice and conclusions of domestic courts, made after the reform, were analyzed, and attention was also paid to the conclusions of the European Court of Human Rights, in the context of: the expediency of empowering the prosecutor’s office powers to represent the interests of the state in civil proceedings; prevention of duplication by the prosecutor of the functions of bodies authorized to perform state functions; the need to observe the principle of equality of participants in the legal process before the law and the court, as well as paragraph 1 of Article 6 of the Convention “On the Protection of Human Rights and Fundamental Freedoms”.
History of appeal of notarial deeds or refusal to perform them in court in Ukraine (late 18th - early 20th centuries)
Authors: Dzhuga M. V. 
Published: February 2024

The article is devoted to judicial control over notarial activities during the times of Austrian and Russian rule on Ukrainian lands (end of the 18th - beginning of the 20th century).
It is noted that the 19th century is a significant period for the domestic notary, since it is at this time that it is formed as an independent institution in the system of law enforcement agencies. Two types of notaries were built on Ukrainian lands as part of the Austrian and Russian empires: Latin and state. As a result, the author conducts a comparative legal study of the mechanism of challenging notarial actions or refusal to perform them in court in different types of notary offices that were built in Ukraine at that time.
It is claimed that the Russian notarial legislation was based on the Austrian one, in particular the Austrian Notarial Order of 1855 was laid as the basis of the Russian Regulation on the Notarial Part of 1866.
It is concluded that it was not possible to build a Latin-type notary in Russia due to the lack of civil society and the prerequisites for its formation, as well as the desire of the state to put notary bodies under its control.
On the other hand, the mechanism of judicial control over the activities of notaries in the two empires was similar. A notary public could be subject to civil, criminal and disciplinary liability for failure to fulfill his duties. It was within the framework of the latter that the institution of judicial appeal of notarial acts or refusal to perform them developed. Disciplinary proceedings carried out by the courts (in Austria also by the notary chamber as a notary self-governing body) regarding the consideration of such complaints were carried out outside the civil process, but it was possible to file claims to challenge the legal force of notarial acts under the rules of civil procedure. This was allowed by both the Russian Statute of Civil Procedure of 1864 and the Austrian Civil Procedure Code of 1895.
