Comprehensive Analysis of Portfolio Optimization Using the Markowitz and Index Models
Authors: Luo Ziye
Published: October 2024

Harry Markowitz’s 1952 systematic approach to optimizing the trade-off between risk and return, known as Modern Portfolio Theory (MPT), revolutionized investment strategy. The objective of this final project is to apply the Markowitz and index models to provide a comprehensive analysis of portfolio optimization and conduct a comparative examination of the two models. By utilizing 20 years of historical daily total return data for 10 selected stocks within the S&P 500 Index, the study will develop optimal portfolios under various realistic constraints, such as typical leverage limitations and short selling restrictions. Additionally, the study evaluates the performance of these models and demonstrates that while index models offer computational simplicity, there are some drawbacks. In this scenario, a Markowitz model will generally provide a more precise risk-return optimization. Finally, the findings highlight the substantial influence of real-world constraints on portfolio management, which can significantly alter the efficient frontier and the structure of the optimal portfolio. This article, in the chapter on future research, proposes some possible future research directions, including the integration of behavioral finance elements and dynamic portfolio optimization, and furthermore discusses the implications of these research results.

Authors: Cheng Shaobo
Published: October 2024

In this study, the key factors affecting football player value were analyzed using a multiple linear regression model. The analysis considered variables such as nationality, location, historical achievements, experience, skill level, and market value. The results indicate that a player’s competitive level significantly enhances their value, while there is a negative correlation between market value and player value. The relationship between experience and value is complex and requires further exploration. Additionally, the study examined the distribution of players from various countries in the English Premier League, with French, Spanish, and Brazilian players ranking highest in appearances. French and Spanish players are versatile across positions, while Brazilian players excel primarily as forwards. Visual analyses demonstrated the proportions and performances of players in different positions, confirming the positive correlation between competitive level and net worth and the negative correlation with market value. The intricate relationship between experience and net worth was also highlighted. These findings offer valuable insights into the determinants of football player value and provide data to support team management and future research.

Authors: Xu Jizheng
Published: October 2024

With the invention and application of artificial intelligence products into modern society, robot pets have become one of the important products. At present, along with the gradual integration of robot pets into human life and becoming people’s intimate companions, more and more people begin to pay attention to the social identity of robot pets. In order to clarify the social identity of robotic pets in modern society, this study used questionnaires and interviews to collect the acceptance attitudes and perspectives of residents from the Yangtze River Delta region toward robotic pets as companions. It is found that there is diversity in public acceptance of robotic pets, and that health, emotional needs, and the function of the robots are important factors influencing people’s choice of robotic pets. Regarding the social status of robotic pets, some people believe that robotic pets should be regarded as an integral part of society. While others believe they lack socio-emotional attributes and should not have a social identity. In the future, pet robots will move toward personalization, multifunctionality, or cross-industry cooperation, where their social identity is expected to be strengthened. In conclusion, this study organizes the social cognition of robotic pets, gives an empirical basis for the study of the social identity of robotic pets, and provides guidance for the future direction of AI products.

Effects of Increased Adult Hippocampal Neurogenesis on Neuronal Output from the Subiculum to the Lateral Hippocampus under Anxiety
Authors: Tang Lienyi
Published: October 2024

Numerous studies assessed the important involvement of adult hippocampal neurogenesis (AHN) in the regulation of stress. Although the precise processes underlying the promotion of AHN on the recovery of anxiety-induced symptoms have been thoroughly examined, they are still unclear.We observed the subiculum region and its neuronal output to the lateral hippocampal formation, which may serve as a conduit between AHN and the recovery from depression.In order to cultivate AHN with exercise and fluoxetine injection independently, we employed a mouse model. We then used FosTRAP2, PET, and fMRI to measure the subiculum’s neural activity during anxiety.When considered collectively, our findings imply that raising AHN in anxious mice modifies the way some subiculum neurons in the lateral hippocampal region output.

Authors: Ding Ying
Published: October 2024

The complexity and severity of brain diseases have led to increased focus on their diagnosis and treatment. Due to the inherent drawbacks of manual medical diagnosis, such as error-prone and costly, and the recent widespread use of Artificial Intelligence (AI) in medicine, it is a worthy topic to explore machine learning in diagnosing brain diseases utilizing Computed Tomography (CT) and Magnetic Resonance Imaging (MRI). In this paper, three brain diseases using CT or MRI datasets from Kaggle were merged and processed, and then three models of decision tree (DT), random forest (RF) and K-Nearest Neighbors (KNN) were used to make classification prediction. Furthermore, their performance was compared through classification reports and confusion matrix to analysis results. The results showed that DT performed worse than the other two models in this task, with an accuracy of 0.91, whereas RF and KNN performed similar overall, each achieving an overall accuracy of 0.96. Notably, RF exhibited less confusion, especially between some similar categories, which indicates the ability of handle complex data more effectively. Additionally, the strengths and weaknesses of the three models are discussed in the paper. These experimental results show that machine learning model, particularly RF and KNN, is a useful tool for diagnosing brain diseases with high accuracy, which could substantially assist clinical practices by providing reliable and efficient diagnostic support.

Electrochemical Biosensor for Detecting both Pb2+ and Hg2+ in Human Blood
Authors: Sun Chenxi
Published: October 2024

Many studies have demonstrated that lead ion ( Pb2+ ) and mercury ion ( Hg2+ ) are harmful to human health. Lead was found to accumulate in the kidney, leading to oxidative stress, apoptosis, and inflammation in the nephrons, and possess marked testicular toxicity. Mercury is well-known to produce nephrotoxicity, inflammatory responses and induce oxidative stress and apoptosis. These heavy metals can enter the human body in various ways, such as through skin or inhalation routes, or contaminated drinking water and food.  But heavy metal poisoning is not easy to diagnose because existing detecting measures has many disadvantages cause them can’t widely spread. So, seeking an easy way to detect them in human blood to discover lead or mercury poisoning is an unmet need. This paper develops a new reusable biosensor for detecting both Pb2+  and Hg2+  in human blood. This work is based on the reaction between guanine and  Pb2+  form of G-quadruplex and Hg2+  connect two thymines together cause the variation of electrochemical signal. The signal is magnified by methylene blue-gold nanoparticles (MB-AuNP) to increase the limit of detection Although the reuse part of sensor is still in theory, but this approach can make the cost of sensor low and create the feasibility of recycle. Overall, providing a new idea to make contributions to the prevention of heavy metal poisoning is the reason why this study is conducted.

Análisis semiótico de las heráldicas territoriales de Latacunga, Pujilí y Saquisilí y su incidencia en la identidad cultural
Authors: Moreno Díaz María Caridad , Astudillo Mamarandi Alfredo Mauricio
Published: October 2024

La ineficacia en la comunicación visual que existe desde las heráldicas a la población no permite la trascendencia de la identidad cultural. Heráldicas que, desde los inicios, el ser humano usaba para identificar y diferenciar una comunidad de otra. Primitivamente se hacía uso de marcas o inscripciones, pero, con el pasar del tiempo estas marcas evolucionan en conjuntos de elementos propios de la comunidad a la que representan, actualmente conocidos como heráldicas, cuyo fin hace evidente las habilidades, las
costumbres, en sí la cultura y sociedad a la que representan. El objetivo de estudio es determinar el nivel de comprensión e identificación de cada símbolo presente en las heráldicas cantonales de Latacunga, Pujilí y Saquisilí y su incidencia cultural en la población. Para lo cual se llevó a cabo una metodología investigativa
basada en el análisis semiótico de los elementos presentes en las heráldicas cantonales mencionadas a través de una encuesta y cuyos datos recabados se analizaron cuantitativamente, para determinar la comprensión de cada elemento y su significado, determinando la efectividad de la comunicación visual.
Obteniéndose como resultado una población escasa en codificación y significación de los elementos constitutivos de las heráldicas contradiciendo la teoría de Humberto Eco y que no comprenden el mensaje transmitido, debido a los ineficaces medios de transmisión de información mencionada por Lasswell y las ambigüedades de los símbolos, que únicamente son reconocidos gracias a sus características de semejanza con el objeto representado.

An Appraisal of the Conduct and Character of Men in the Society: Perspectives of Yorùbá Female Novelists
Authors: Asiwaju Jumoke Helen
Published: October 2024

In Yorùbá literature, the focus has often been on the roles, struggles and societal expectations of women. However, a notable silence exists in the exploration of men’s character. This apparent oversight exposes the prevailing patriarchal system, which has historically cast men into roles defined by fatherhood and as the head of the family. This narrative portrays men as guardians of traditions, providers and the pillars of family structures. Yet, beneath the surface lies the curiosity concerning the authenticity of these portrayals. Two questions become pertinent: one, do these depictions truly reflect the male identity, or are they just shadows cast by a societal construct designed to reinforce established norms? Two, are men truly capable of meeting the standards set for them, or are they merely being shielded from scrutiny by a narrative that perpetuates their idealized roles? Using the Feminist theory and a Sociological Approach, with narratives from fifteen selected novels authored by Yorùbá women, this study scrutinizes the narratives surrounding the portrayal of male conduct and characters in society by questioning the authenticity of the pedestal upon which men are placed and the realities that shape their lives arising from their conducts, and the character displayed. Findings from the Yorùbá female novelists’ perspectives reveal that lots of men act contrary to the assumed pattern of portrayal. Their shortcomings are unknown to society because the women in the men’s lives cover up the inadequacies of such men. These revelations confirm that the portrayal of men as superhuman beings does not truly represent their conduct and character in society.

Published: October 2024

In the recent period, the Advocate profession has received very sharp attention from the public, especially those who have experienced cases in court. Often there are cases of an advocate making a mistake in providing legal assistance. This results in a negative assessment from the public. The negative assessment of the public towards advocates will have an impact on the image of the legal institution (law firm) that houses them. Currently, many complain that advocates lack sufficient competence in carrying out their duties. Based on these problems, a question arises how to improve the competence of an advocate. So this study aims to design the concept of a model for improving the competence of advocates along with the variables and indicators that follow. The method used in data collection is a survey method by distributing questionnaires to 101 advocates in various law offices in Yogyakarta. The data obtained were analyzed using Structural Equation Modeling (SEM) through the AMOS 24 application program. The results showed that there was an influence between knowledge and competency (H1), there was an influence between skill and competency (H2), there was an influence between attitude and competency (H3) and there is an influence between motivation and competency (H4). Thus, based on the results of the AMOS analysis, the concept of an advocate competency improvement model was obtained.

Published: October 2024

A produção agropecuária no estado de Mato Grosso e dos 31 municípios que compõem as principais áreas de contribuição do Pantanal setentrional é voltada para o mercado internacional de commodities e, possui assim, importância significativa para a economia brasileira. Baseado em análises comparativas de dados secundários, o presente trabalho avalia em escala regional, estadual e nacional a evolução da produção agropecuária e busca identificar os fatores que contribuíram para as suas mudanças entre os anos de 1980 a 2016. Em função do nível de agregação espacial, foram detectadas expressivas diferenças na evolução temporal dos principais produtos vegetais e animais. Até o início do século 21 e principalmente nas escalas estadual e regional, o aumento vertiginoso da produção agropecuária foi fomentado por desmatamentos. Estes que foram mais expressivos a partir de 2005 e dentro da escala regional, o aumento da produção foi adicionalmente garantido por processos de intensificação no plantio, com aumento da produtividade e da inclusão de áreas anteriormente utilizadas para pecuária e consideradas inaptas para o plantio de soja e milho. Impulsionado por vantagens geoeconômicas, a região se tornou e prevalece como uma das principais produtoras de algodão no estado, cultura de alto valor agregado.

Authors: Al-Haj Husain Adib , Salzer Esra , Stadlinger Bernd
Published: October 2024

Soft tissue lesions are among the most prevalent forms of tumors or tumor-like alterations within the oral cavity. They exhibit a wide spectrum of characteristics, ranging from benign, noninvasive lesions to malignant tumors, which collectively present a diagnostic challenge.
A 67-year-old patient presented with an incidental finding of induration on the right cheek during dental hygiene. The intraoral examination revealed a soft, non-tender swelling measuring 20 mm in diameter. The sensitivity and percussion tests for the teeth in the fourth quadrant yielded unremarkable results. Panoramic radiography (OPG) revealed tip-ping of the premolars and an unclear apical finding in region 44. Cone-beam computed tomography (CBCT) revealed a sharply defined, lobulated hypodense lesion in the right buccal area. To clarify the diagnosis and optimize perioperative management, a 3 Tesla dental magnetic resonance imaging (MRI) scan was performed. This identified a 23×6×23 mm lipoma along the right mandibular ramus, causing detachment of the buccinator and de-pressor anguli oris muscles. A cinematic rendering reconstruction derived from the MRI data facilitated enhanced visualization for preoperative planning.
The surgical excision was performed under local anesthesia, resulting in the successful removal of the neoplasm while preserving the mental nerve and submandibular gland. Histo-pathology confirmed the presence of a lobulated mature cell lipoma. The patient exhibited no complications during the removal of the sutures, with complete wound healing and no recurrence observed.
This article highlights the efficacy of advanced MRI diagnostics and post-processing techniques in the management of ambiguous soft tissue neoplasms.
Problem of Surface Waves on Water in Higher School Laboratory Workshop
Authors: Chkhartishvili L , Chikhladze M , Kantaria I
Published: October 2024

Traditionally, in lecture courses on General Physics, the example of waves propagating on the water surface is used for the qualitative description of wave phenomena. At the same time, in corresponding laboratory courses, there are almost no quantitative tasks on the same topic, the purpose of which would be to measure the surface wave characteristics. The reason for this difference must be associated with the complexity of the physical mechanism of generation and propagation of waves on the water surface. In this work, a laboratory problem has been developed to measure the group velocity of circular waves traveling on the water surface. It uses a standard laboratory water tank equipped with a surface wave generator. The proposed experiment offers an opportunity for quantitative measurement of surface wave characteristics, a dispute of only qualitative observations of wave phenomena commonly found in current curricula, due to the introduction of two improvements. First, to produce the water waves’ rich in-contrast representations on a screen, the optimal generator amplitude is specially set for each experiment; and second, to measure the group wavelength, the device magnification is preliminary calculated based on the laws of geometric optics. The tests carried out have shown that the relative accuracy of these measurements is quite acceptable: within a few percent. The introduction of the problem of surface waves on water into the General Physics laboratory workshop for engineering specialties of technical universities will contribute to improving the quality of mastering the subject by students.

Authors: Hamzah Hamzah
Published: October 2024

Welding is a job with a high risk of danger for the welder, such as a hot working environment, dehydration, eye complaints, and uncomfortable working positions. One of the conditions that often occur in welding workers when carrying out work is the position of the welder's body when carrying out welding, which is required to stand. This condition will cause complaints that the welder feels because carrying out the welding process takes a long time. This causes the welder to experience pain in the legs and back and, if done continuously, will trigger long-term illness. The method used in this research is method Rapid Entire Body Assessment (REBA). From the results of manually calculating the REBA method, a score of 2 is obtained, which can be interpreted according to the REBA Classification and Risk Level as low risk. Based on the results of work posture testing on the welding section, the workload of the workers has been reduced from 5 to 2. Therefore, the best position is welding while standing with the body upright; this will help the welder work without injury and has been tested using the REBA method.

Basketball is a predominantly aerobic sport during which high-intensity anaerobic actions are performed. In recent years, this characteristic has evolved in terms of demands on the athlete and intensity of the competition, implying an increase in the number and duration of explosive actions. To meet the demands of this sport, good technical, tactical, physical and mental training is required. The research purpose was to determine the anthropometric and motor differences between two male basketball teams from a private club, both playing in the U15 age category. The study included 32 athletes who were divided into two groups. One group was made up of 16 players representing the club’s elite team, and the other group also consisted of 16 players representing the club’s secondary team for this age category. All players were tested in the same sports hall on two different days, during their training for the U15 National Basketball Championship of Romania. Anthropometric and physical characteristics were measured using a test battery with six variables: Height, Weight, Body mass index, 10 m Sprint, Standing long jump, Vertical jump, and Little Marathon. The methods used were: literature review, observation, mathematical statistics, tabular and graphical methods. Differences in anthropometric and physical values between the basketball players of the two teams were determined using the t-Test for independent small samples (Assuming Equal Variances). Our research hypothesis is confirmed, since there are significant anthropometric and motor differences between the players of the two representative club teams, justifying the presence of the elite team in the U15 National Basketball Championship.

EMS Fitness is an electrical muscle stimulation, a full-body training method that offers the combination of strength training and cardio training through a machine that uses electrical impulses to stimulate muscle contraction. The aim of the study was to follow the effects of electrostimulation training on body composition, weight loss and muscle strength increase. Ten people, women and men, aged between 25 and 50, were studied. We want to demonstrate the hypothesis that the use of the EMS Fitness technique over a period of 90 days will lead to a decrease in body weight, optimisation of body mass index and increase in muscle strength. Participants in the exercise group performed 12 weeks of high-intensity training using specific EMS equipment in an Xbody. The objective of the experiment was to identify whether the use of EMS technology contributed to changes in body mass, skeletal muscle mass, body fat and visceral fat. All exercise sessions were constantly supervised; in addition, exercise intensity, volume and frequency were recorded in training logs. A body composition scale was used for testing, which provides accurate body analysis using BIA technology. The training scheme was used for 12 weeks, changing the dosage and intensity for each subject, with the first signs of weight loss appearing after the first week. Methods used in the research: experimental method, graph-tabel method, observation method, bibliographic study method. Our results support the hypothesis, as the use of the EMS Fitness technique over a period of 90 days led to decreased body mass, optimized body mass index and increased muscle strength. In conclusion, I believe that people in Romania should have a wider openness in practicing physical exercise in their free time in order to develop a healthy generation and decrease the possibility of reaching the stage of obesity and stopping diseases, and a good help in achieving this goal is presented by training using EMS Fitness technology.

Background. The major importance of physical education lessons in higher education is achieved through their contribution to maintaining health, to compensating for the increased intellectual efforts generated by passing exams. Basketball training helps in the positive development of the general and specific motor capacity required by the subsequent professional activity, as well as to the achievement of the necessary framework for recreation and the practice of the favorite sport. Therefore, at this level, the achievement of the following objectives will be mainly pursued: – maintaining health and increasing the ability to adapt to changing conditions; – the development of the general motor capacity necessary to carry out the sports activity; – improving the somato-functional indices and optimizing the relationship between them. Physical training is a component of sports training that constitutes the pivot for all other components, constituting the starting point for the entire training process (Ardelean. T, 1996). General physical training has different weightages in training, depending on the experience of the students and for the training of beginner students it is very important that the time allocated is much greater than in the training of students from older years. Objectives. This study aims to find and offer, through specific basketball exercises, how to improve the quality of speed. Speed should be present in the equipment of the "motric luggage" of each student, considering the evolution of our modern society, to dynamic games. This speed quality motor offers several advantages to basketball players: – allows the execution of thechnical and tactic actions in a sustained rhythm. – gives the player a high degree of complexity and dynamic adaptation to playing basketball. – develops the player's thinking, attention, rationality and ability to concentrate. Methods. For this study we used the following research methods: documentation, observation method, statistical method, graphical representation method and experimental method. Results. For checking the motility of students enrolled in educational experiment we chose the following control samples: speed running 15m, speed running 20m and dribbling through cones. Conclusion. The results of this test depend both on the execution speed and the technique in performing the dribbling. We therefore recommend that these results can be improved both by increasing the speed of movement and the execution technique.
Tradisi Menjual Anak Dalam Masyarakat Suku Bugis Makassar Ditinjau Dari Perspektif Hukum Nasional
Authors: Dyah Auliah Rachma Ruslan
Published: October 2024

Dalam masyarakat hukum adat Bugis Makassar, terdapat kepercayaan bahwa seorang anak yang lahir dengan wajah sangat mirip dengan salah satu orang tuanya dianggap kurang baik, karena dipercaya dapat membuat anak tersebut sering sakit atau bahkan cepat meninggal. Oleh karena itu, menurut kepercayaan masyarakat Bugis, anak yang sangat mirip dengan orang tuanya harus dijual kepada orang lain untuk menghindari hal-hal buruk.  Penulisan jurnal ini bertujuan untuk menganalisis lebih lanjut dari sudut pandang hukum nasional terkait tradisi menjual anak dalam masyarakat Bugis, khususnya apakah makna "menjual" dalam tradisi tersebut sama dengan konsep jual beli sebagaimana diatur dalam Pasal 1457 KUH Perdata, dan apakah ada implikasi hukum dari tradisi tersebut. Penelitian ini menggunakan metode penelitian hukum normatif dengan pendekatan undang-undang. Sumber bahan hukum yang digunakan meliputi bahan hukum primer dan sekunder, yang dikumpulkan melalui studi pustaka dan dianalisis secara kualitatif serta disajikan secara preskriptif. Dalam tradisi menjual anak di masyarakat Bugis Makassar, tidak ada transfer tanggung jawab, karena anak tetap berada di bawah asuhan orang tuanya. Tradisi ini tidak dapat dianggap sebagai perjanjian jual beli yang sah menurut hukum, karena bertentangan dengan ketentuan objek perjanjian. Tradisi ini hanya merupakan bagian dari adat istiadat setempat yang dipercaya dapat mencegah hal-hal buruk, tanpa menimbulkan akibat hukum.

Régimen jurídico que debe regir el ingreso en residencias de personas mayores. Aplicación de la Sentencia del Tribunal Constitucional 34/2016, de 29 de febrero de 2016, recurso de amparo 4984/2014
Authors: González Casso Joaquín
Published: October 2024

La Sentencia del Tribunal Constitucional 34/2016, de 29 de febrero, y la posterior Sentencia 132/2016, de 18 de julio, han supuesto un cambio radical en el tratamiento del régimen jurídico que debe regir el ingreso en residencias de personas mayores en los juzgados de primera instancia. La recepción de dicha doctrina supone la necesidad de aplicar soluciones a una cuestión que el legislador contempló para los internamientos en centros psiquiátricos, pero no para los ingresos en centros geriátricos.
El apoyo en el ejercicio de la capacidad jurídica
Authors: Salas Murillo Sofía de
Published: October 2024

Se analiza el significado del concepto apoyo en el ejercicio de la capacidad jurídica en el texto de la Convención sobre los Derechos de las Personas con Discapacidad de las Naciones Unidas y en la interpretación de la Observación General n.º 1, así como la interpretación que se le ha dado en el sistema español desde la aprobación de la Convención hasta la fecha de esta ponencia, sin olvidar las propuestas de plasmación legislativa del mismo, en especial en el anteproyecto en su versión de 14 de enero de 2019. A continuación, se abordan algunas cuestiones problemáticas, tales como los apoyos informales y su encuadre jurídico, la proyección temporal de los apoyos al proceso previo a la declaración de voluntad, la duda sobre si se contempla el derecho a no recibir apoyos o a prescindir de su contenido y la compatibilidad del mantenimiento de sistemas sustitutivos con la noción misma de apoyo.
¿Qué es un mediador?
Authors: Vall Rius Ana María
Published: October 2024

Este trabajo trata de presentar una visión amplia sobre la figura de la persona mediadora: qué es, qué hace, cómo lo hace y cómo puede variar su labor según el ámbito de conflicto. Asimismo, qué puede aportar de diferente y cómo puede definirse la persona mediadora en función de la actividad que desempeña, la filosofía en la que se funda y en contraste con la actividad de distintos profesionales y operadores jurídicos que también trabajan en el abordaje del conflicto y con los cuales colabora. Conocer las funciones de la persona mediadora, las actuaciones que le son propias y las que no también puede ayudar a establecer el perfil de este tipo de profesionales con sus diferentes matices, sus límites y las diferencias complementarias con la actuación de otros profesionales.
La construcción normativa y jurisprudencial del principio de igualdad de género en la Unión Europea. Guía para jueces españoles
Authors: Ordóñez Solís David
Published: October 2024

Los tratados constitutivos, las directivas y la Carta de la Unión Europea han consagrado un derecho fundamental a la igualdad entre mujeres y hombres y en otros ámbitos como la religión, las preferencias sexuales, la edad o la discapacidad. La jurisprudencia del Tribunal de Justicia ha subrayado la eficacia de estas normas, ha depurado los derechos nacionales de discriminaciones y ha interpretado las acciones positivas empeñadas en conseguir una igualdad de género, no solo formal, sino también real. La interpretación del Tribunal Europeo de Derechos Humanos ha sido complementaria y se ha pronunciado sobre la obligación positiva de las autoridades y la protección de las víctimas de la violencia de género frente a los agresores. Los tribunales españoles, especialmente la jurisdicción social, han contribuido al desarrollo de esta jurisprudencia europea y a la recepción del principio de igualdad mediante el planteamiento de numerosas cuestiones prejudiciales. El objetivo del estudio es conocer mejor la interacción del soft law con el derecho positivo, la interpretación de la Constitución española sin vulnerar la Carta o el Convenio Europeo y el diálogo de los jueces en Europa en materia de igualdad. En realidad, los jueces, al resolver litigios, deben determinar si procede plantear cuestiones prejudiciales europeas o de inconstitucionalidad y deben decidir si cabe anular, inaplicar o adoptar una interpretación del derecho español de conformidad con el ordenamiento europeo.
