Effect of Teachers’ Knowledge Sharing Behavior on Students’ Entrepreneurial Motivation in Social Media Environment
Authors: Li Jiajing , Qin Jian
Published: January 2022

The improvement of social media network and the enrichment of social media make the communication of modern people more convenient, break through the limitations of time and space, and meet the knowledge sharing between different groups. This study provides a model framework for teachers to promote students' entrepreneurial motivation through knowledge sharing. Through the questionnaire survey, the sample data of 111 teachers and students in 5 higher vocational colleges in Hangzhou, Zhejiang Province were collected. Through path analysis and mediation effect analysis, the four hypotheses of the model are analyzed and tested. The results show that the overall Cronbach coefficient of the questionnaire is 0.935, which has high reliability. Kaiser – Meyer – Olkin (kmo) value is 0.884, greater than 0.8. Research data information is very suitable for extracting information. Teachers' knowledge sharing can not play a direct and positive role in students' entrepreneurial motivation. Knowledge reciprocity between teachers and students can promote students' entrepreneurial motivation. The results of this study have important reference value for fully understanding how teachers' knowledge sharing behavior stimulates students' entrepreneurial motivation.
Prediction of College Students' Psychological Crisis with a Neural Network Optimized by Harmony Search Algorithm
Authors: Jia Zhiping
Published: January 2022

Despite the growing concern with students’ mental health education, there are neither extensive research on stressors of psychological crisis, nor targeted research on the psychological crisis warning of college students with different levels of psychological crisis. To solve the problem, this paper aims to explore the psychological crisis warning and physical education (PE) intervention of college students based on artificial neural network (ANN). Firstly, the important evaluation indexes were determined for psychological crisis warning of college students; according to the adverse reactions and performance of college students in physiology, cognition, emotion, and behavior, the index data were processed by partial least squares (PLS) method. Next, a psychological crisis warning model was developed based on the optimized ANN: the harmony search (HS) algorithm was improved based on the differential evolutionary (DE) algorithm, and then used to optimize the backpropagation neural network (BPNN). The proposed model was proved feasible and effective through experiments.

Developing Musical Creativity Through Activity Theory in an Online Learning Environment
Authors: Chien Chih-Feng , Walters Brent G. , Lee Ching-Yieh , Liao Ching-Jung
Published: January 2022

An online general education platform, e-Holistic (e-HO), was developed to support digital learning. Following Burnard's (2007) adoption of Activity Theory (AT) in designing music education to galvanize learners' creativity, the authors' study extended her theoretical framework through a hypothetical model they designed. From AT, this article investigates a number of elements—musical activities (tools), e-HO (community), emotional arousal (object), and musical creativity (outcome). Through the operation of the AT system, 733 students immersed in musical activities in e-HO were able to compose music even without any musical background. The purpose of this article is to report how an e-HO online activity helps arouse students' emotions and inspire their musical creativity. The structural equation modeling (SEM) analysis indicates that all research hypotheses were supported, and the musical activities on e-HO predicted 71.6% of students' self-assessed musical creativity. Finally, the implications of the authors' findings are reported for the future development of online musical education.

This chapter explores how enterprise pedagogy and entrepreneurial pedagogy (i.e., authentic learning experiences) provide opportunities for students to reflect on, and prepare for, the likelihood of multiple jobs and roles in their upcoming career paths. Podcasting as an authentic learning tool is explored through the development of MusicWorks, a podcast series giving voice to the multiple career paths of industry and educational leaders in music.
Music Composition and Kyosei
Authors: Kaschub Michele Ellen
Published: January 2022

The spirit of cooperation central to kyosei is a critical component in the creative corners of American music education. This chapter will describe a project that involved the creation of a hybrid space where a music teacher-educator and practitioner worked with pre-service teachers and middle school students to explore teaching and learning music composition. By recasting who is considered an expert, rethinking institutional boundaries, and immersing in project-based learning on multiple levels, teacher education programs and schools can better identify their challenges and explore possible solutions. Though not part of initial program planning, the principles of kyosei were evidenced in the evolution of complex understandings developed prior to and throughout the project, in the inclusive nature of project-based learning by pre-service teachers and music students, and in the professional relationships—and, ultimately, the friendships—that emerged as the teaching-learning community matured.

What Turkish Women Need to Advance in Academia
Authors: Tatarlar Ceren Deniz
Published: January 2022

As can be seen in most Eastern or Middle Eastern countries, the primary role of women has been defined as motherhood or to be a wife to a man. The fact that women have a role apart from these is seen as a radical change. In Turkey, where the base of this chapter is, there have been many struggles to change this situation from past to present and to maintain the male-female equality. Yet, this “equality” cannot be seen in some broad areas in life such as work-life. The aim of this chapter is to make visible what women have encountered in order to advance in academia through some real-life stories.

Published: January 2022

The present study considers the effects of spatial neighborhood relations on the economic growth and urban identities of two Turkish cities over the course of the last century. This chapter sets out a number of reasons for the conflict between center-provincial arguments and concludes that the urban experience of Safranbolu relative to Karabük and the central-provincial dilemma is a manifestation of a political, social, and urban failure to accommodate the needs of a traditional regional centre in the early 20th century.
A Survey on Georgian and Byzantine Architecture and Their Cultural Encounters
Authors: İşler Bülent
Published: January 2022

Georgians lived in Northeastern Anatolian and south of the Caucasian Mountains during the Middle Ages and had centuries-long relations with the neighboring Byzantines. Christianity was a common denominator, with both cultures adopting it as their official state religion in the 4th century AD. They also faced common threats to their security, and while the quality of their relations varied over time, their rulers intermarried and strong ties emerged. Yet even from the earliest encounters, it is seen that the Georgians created unique artforms in line with their economic and geographical conditions, personal needs, tastes, and opportunities. This chapter highlights the unique architectural characteristics of Georgian sacred art and cultural heritage from examples located in and around the boundaries of the Georgian Republic and Northeastern Turkey. These trace the emergence and continued use of distinctive features in plan types, interior and exterior arrangements, materials, craftsmanship, mural decorations, and sculpture.
Colonial Encounters in Space
Authors: Altinoz Meltem Ozkan
Published: January 2022

This study focused on the Great Sacred Center of the Aztecs in Mexico, which was completely destroyed, and in its space, a huge colonial city square, Plaza Mayor, was constructed by the Spaniards in the 16th century. Passing time never diminished the spatial importance of Plaza Mayor. The city square hosted religious and political identities for a long time. In recent times, folk used to meet, sell their productions, protest, or celebrate national and religious festivities in the center; thus, it will be concluded that recently Zócalo has value for every person, which charges a public space character to it.
Ornaments as Means of Communication
Authors: Ruppio Christin
Published: January 2022

A few years after art patron and museum founder Karl Ernst Osthaus (1874-1921) had his family residence—the Hohenhof (1908-1906)—built, he decided to have his study redesigned with a striking ornament. The chapter aims to explain why Osthaus had his study redesigned and how impulses from Islamic ornamentation and the world art collection at his museum—the Folkwang—were tied to this process. It will become apparent that to Osthaus this was not a process of mere decoration after Orientalist fashion but rather a way to exemplify how impulses from other cultures can lead to a new way of artistic practice. Osthaus believed that applied arts and architecture were the most important means of initiating social change, and his study became a place to discuss the significance of Eastern artistic practice to contemporary design questions.

Public transportation provides opportunities for mobility, access to basic services, work, and studying. Generally, commuters often experience waiting at a transport terminal for transport controllers to get information about transport facilities (means of transportation). In order to reduce the waiting time at transport terminals, an automated enquiry system becomes necessary. The transport enquiry system not only provides bus details but also helps in travel planning and saving of enormous timing of the user, which would have been spent in waiting at the bus station. The aim of this research work is to develop a voice-based automated transport enquiry system. The voice application is important to help people, especially those with educational inefficiency and visual impairments, have access to the functionality of the transport enquiry system. A test case of FUTA shuttle system was used. The evaluation of the system performance is based on three metrics: response time, efficiency, and functionality.

Authors: Lavanderos Leonardo P. , Lavanderos Leonardo , Morales Ramón , Araya Abelardo
Published: January 2022

Codelco Chile will revolutionize underground mining as we know it today. The large infrastructure developed should be automated and monitored according to the most recent advances in the field. It implies a systemic conception of the operation to allow the remote control of communications and connectivity of the organization, making possible its coordination, cohesion, and management. The foregoing requires the implementation of an integrated technological model, which includes semi-autonomous operations from an integrated operations and control centre, but for this to happen, the entire organization needs to be adjusted. We propose a systemic model based on the control of the Organizational Waste (Variety No Required VNR). To reduce the loss of value (waste) need to evaluate and correct the incoherence in the decision-making processes, break in the continuity of the information flows by poorly designed organizational structures and by the elevated risk in redundancy values because of the disconnection between these.
Bullying, Cyberbullying, and Hate Speech
Authors: Cohen-Almagor Raphael
Published: January 2022

The Internet's design and raison d'être are complete freedom, but complete freedom might lead to anarchy and to harmful and anti-social activities. In this paper I address the concepts of moral and social responsibility, applying them to the Internet realm in considering the most troubling phenomenon of cyberbullying that results in loss of life. Specifically, I probe the moral and social responsibilities of Internet users (agents), of parents and of the education system in fighting cyberbullying. Balance needs to be struck between two most important principles: freedom of expression and social responsibility. Illustrative examples in which this disturbing and harmful phenomenon of cyberbullying had cost young life are mentioned. It is argued that all relevant stakeholders need to think of the consequences of their conduct, that Internet abusers should be accountable for their wrongdoing and be penalized, and that people who have the ability to stop or at least reduce the risk of cyberbullying should take proactive steps, exhibiting zero tolerance to cyberbullying.
Condotte suicidarie e adolescenza nel dibattito attuale
Authors: Di Pietro Maria Luisa , Lucattini Adelia
Published: January 2022

L'articolo si propone di formulare una risposta a tre domande: 1. perché un adolescente può suicidarsi; 2. le cause di tale gesto; 3. la prevenzione di tale scelta di morte. Dopo avere brevemente passato in rassegna le c.d. "condotte suicidarie", gli Autori analizzano il problema del suicidio nell'epoca adolescenziale relativamente all'epidemiologia ed ai mezzi utilizzati per il tentativo di suicidio. Riguardo all'eziologia del suicidio, l'articolo nota come tale gesto solo apparentemente caratterizzato da improvvisatezza ed incomprensibilità. In realtà, il suicidio è da considerare come atto conclusivo e manifesto di un complesso insieme di processi, fantasie, desideri e vissuti determinati sia dalla realtà psichica interna sia dalle vicende relazionali esterne dell'ambiente sociale in cui vive l'adolescente. Risulta perciò difficile parlare di cause scatenanti del suicidio preferendosi parlare di fattori di rischio. Essi sono: la personalità vulnerabile dell'adolescente; la compresenza di psicopatologie, soprattutto depressione; il rapporto conflittuale col proprio corpo; alcoolismo e tossicodipendenza; la situazione familiare (confl itti irrisolti o compresenza nella famiglia di psicopatologie o condotte suicidarie; l'influenza dei mass media, che possono rafforzare situazioni di "debolezza" dell'adolescente; gli insuccessi scolastici; il fattore socio-ambientale "difficile"; le "fantasie" dell'adolescente suicida. Gli Autori individuano tre livelli di prevenzione del suicidio negli adolescenti: primario, mediante l'attuazione di provvedimenti diretti a tutta la popolazione a rischio; secondario, per evitare l'insorgenza di recidive; terziflrio, mediante il contenimento dei danni conseguenti al comportamento suicidario. L'articolo si conclude con una proposta di educazione alla vita che tenga conto delle tre dimensioni umane: se stesso. gli altri, la trascendenza.
L'eutanasia in Olanda: risposta legislativa ad una prassi iniqua
Authors: Fravolini G. , Mencarelli A. , Mazzeo E.
Published: January 2022

L'articolo prende in esame la situazione normativa sull'eutanasia in Olanda, cercando di sottolineare il significato e la reale portata della innovazione legislativa al fine di contenere le errate interpretazioni secondo le quali sarebbe stata legalizzata l'eutanasia in tale Paese. Considerando, infatti, che in Olanda a partire dal gennaio 1994, l'eutanasia è stata inclusa fra le cause di morte che debbono essere espressamente specificate dal medico al momento del decesso del paziente, sono stati analizzati i tempi e i modi in cui la pratica dell'eutanasia può essere messa in atto. Si sono quindi osservate le modalità secondo le quali la suddetta prassi diventerebbe ex-lege atto non perseguibile per il medico, presentando i requisiti di legittimità e parimenti le ipotesi in cui comunque il sanitario curante potrebbe incorrere in un procedimento penale dal momento che il reato di omicidio resta immodificato nel codice penale, essendone tal une evenienze scriminanti di punibilità. Gli Autori concludono, infine, che ad ogni modo una codificazione normativa in tale ambito ed in tal senso non può garantire la tutela dell'assistito né essere immune da rischi per chi la realizza e, pertanto, ne risulterebbe inopportuna l'ipotesi di attuazione nel nostro Paese.
VIDĒRE EST CREDERE: LA STRUTTURA AD ALTA RISOLUZIONE DEL CANALE DEL PACEMAKER HCN4
Authors: Moroni Anna
Published: January 2022

HCN channels (HCN1-4) generate the If current that controls automaticity and rhythm of the heartbeat. Using single-particle electron cryo-microscopy (cryo-EM), we obtained the structure of HCN4, bound and unbound to the cAMP ligand and with the pore in open and closed configuration. Analysis of the structures reveals a coordination site for the Mg2+ ion which, by linking two domains of the protein, facilitates channel gating by cyclic nucleotides. The open pore configuration used in molecular dynamics simulations provided information on the mechanisms of permeation of K+/Na+ ions and on the mechanism of action of ivabradine, a drug used in the treatment of angina.

Authors: Kumar Akhilesh , Gopalakrishnan Maya , Kuri Harshavardhan R. , Bajpayee Archana , Kothari Nikhil , Garg Mahendra Kumar
Published: January 2022

Snakebite envenoming is a common occupational hazard in the tropics. Venom-induced consumption coagulopathy and acute kidney injury are the most frequently encountered complications of viper bites. Diffuse alveolar hemorrhage (DAH) is an unusual presentation reported rarely in the literature. Our case report highlights the uncommon presentation of delayed pulmonary hemorrhage after snakebite envenoming. A 40-year-old healthy man presented to our emergency department after 6 hours of Echis sochureki (a saw-scaled viper subspecies) bite. He had abnormal coagulation parameters and thrombocytopenia with no signs of acute kidney injury. Transfusion protocols were initiated because of active bleeding and a rapid decrease in hemoglobin levels over next few days. Around day 10, his coagulation profile and hemoglobin were corrected, but he developed hemoptysis with rapidly progressive respiratory distress. Computed tomography of the chest was suggestive of DAH and the patient was started on a plasma exchange with pulse methylprednisolone. After the initial worsening, he had rapid symptomatic improvement and radiological resolution. The patient had persistent hypofibrinogenemia, which resolved, and was discharged and remained healthy at the 60-day follow-up. This case highlights a presentation with an initial phase of venom-induced consumption coagulopathy followed by delayed DAH in saw-scaled viper envenoming that was treated successfully with immunosuppressants and plasma exchange.
Affinity study of -lactalbumin nanoparticles in a mixed solvent environment using Laplace transform technique
Authors: Kavitha K. , Palaniappan L.
Published: January 2022

ABSTRACT. Effect of pH and cosolvent on the stabilization of protein structure is a well established study in protein or food science. Of the various interesting applications of protein nanoparticles, making it as a drug or bioactive compound carrier is of vital importance. This application of protein nanoparticle demands the affinity priority of protein with the available components of the medium. The basis of such studies lies in the synthesis of such protein nanoparticles and their characterizations. Secondly the knowledge of priority in affinity of protein to a particular solvent is essential. On this basis, the present work deals with the ultrasonic analysis of hydophobic interactions exhibited by the α-lactalbumin nanoparticle synthesised by heat treatment using acetone as desolvating agent. In order to enrich the variations in hydrophobicity, pH and cosolvent (fructose) are included in the study. The results are compared with one of our earlier work and are interpreted in terms of the interactions existing among the components and the evolved discussions reveal that the bulk nature of the medium is controlled by the existing hydrophobicity interactions. Further, as a novel attempt, the preference of protein particle to interact with a particular solvent in mixed solvent environment is elucidated using Laplace transform technique. This approach is expected to torch light in protein science in fixing the most desirable solvent in mixed solvent environment.

Preparation, spectral study and antimicrobial activity of binary Co(II) complexes derived from 2’-hydroxy chalcones
Authors: Patil P. , Zangade S.
Published: January 2022

ABSTRACT. The present work comprises preparation, characterization, thermal behavior and growth inhibitory activity of some novel Co(II) complexes derived from substituted (E)-1-(1-hydroxy-4-iodonaphthalen-2-yl)-3-phenylprop-2-en-1-one (L1) and (E)-1-(4-bromo-1-hydroxynaphthalen-2-yl)-3-phenylprop-2-en-1-one (L2-L6). Newly synthesized metal-ligand complexes were structurally confirmed with suitable spectroscopic technique such as FT-IR, EPR, NMR (both 1H and 13C). XRD analysis for complex C1 confirmed the crystal system; tetragonal and space group; P 42/n: 2 with unit cell dimensions a, b = 13.3516 Å, c = 10.8009 Å; α, β, γ = 90o. The IR and EPR study demonstrated that interaction between metal ions and ligand occurs through carbonyl oxygen and hydroxyl oxygen. From the values of magnetic moment (μ) it was observed that synthesized complexes (C1-C6) are paramagnetic with three unpaired electrons contain one electron in t2g orbital and two electrons in eg orbitals. Further all these complexes have been evaluated in-vitro for their antimicrobial activity against the Gram positive bacteria Staphylococcus aureus, Gram negative bacteria Escherichia coli and the yeast Candida albicans. The complex C1 showed the significant antimicrobial activity, whereas the complexes C2, C4, C5 and C6 are moderately active against the tested pathogens. The antimicrobial data revealed that growth inhibitory activities of complexes were enhanced comparatively than its respective ligands. The enhanced antimicrobial activity is attributed to the presence of halogens (Br, Cl, I) and hydroxyl (OH) active substituents associated with the basic nucleus of complexes. Therefore, the present study helps to develop a new class of antimicrobial analogues.

Fenomenologia, film i awangarda. O inspiracjach Stefana Morawskiego
Authors:   University of Gdańsk, Poland, Przybysz Piotr J.
Published: January 2022

Phenomenology, Film and the Avant-garde. The Inspirations of Stefan Morawski The article addresses three key issues that are presented in the section of the “Cultural Studies Review” dedicated to the 100th anniversary of the birth of Professor Stefan Morawski. Firstly, the issue of the relationship between Stefan Morawski and Roman Ingarden and his environment, where I draw attention to the role of Roman Ingarden’s phenomenology in building an independent position in Morawski’s aesthetics/philosophy of art. Secondly, in reconstructing Morawski’s aesthetic views on the basis of published film reviews and on the basis of his reflections on film criticism and artistic meta-criticism, I pay attention to the axiological context of the hierarchisation of works of art, which is the basis of this review. Thirdly, I present basic findings on avant-garde and neo-avant-garde art, as well as on avant-garde theory. This provides an opportunity to better recognise what Morawski’s diagnosis of continuity and severance in the historical development of art was in this area. The above three issues are preceded by biographical information, which is continued in the rest of the text. In this way, Morawski’s choices and changes of interests become more understandable and fraught with consequences.
Moroccans’ Behavioural Response to the Development of Digital Tourism
Authors: Laajini Tariq
Published: January 2022

Electronic tourism was born at the crossroads between tourism and electronic commerce. Electronic tourism developed in the 1990s and became widespread with the emergence of the Internet 2.0. This article examines this new disintermediated form of tourism by looking at the new requirements and attitudes of today’s tourists. The analysis focuses on tourists’ behaviour regarding technological tools. It relies on both the conceptual and theoretical frameworks and a qualitative study carried out with four focus groups composed of Moroccan Internet users aged between 16 and 64 years. The results of the study indicate that these technological tools have become an integral part of tourists’ behaviour because they not only facilitate the accommodation search but also significantly influence purchasing behaviour.

Marketing Político 2.0: Estrategias de storytelling a través de TikTok de los dos candidatos a presidente del Ecuador 2021
Authors: Suárez-Tomalá Geovanny , Cochea-Panchana Gerzon
Published: January 2022

El uso de las redes sociales como herramientas de comunicación política es una tendencia que se evidenció con mucha mayor fuerza en Ecuador durante las campañas presidenciales del 2021, las cuales se dieron en medio de la crisis por COVID-19. En dicho marco, el presente documento investigativo presenta como objetivo principal el análisis del uso del discurso como parte de la estrategia de storytelling, implementado por los candidatos Guillermo Lasso y Andrés Arauz en la red social TikTok. La metodología de la investigación fue de carácter mixta, usando como técnica de recolección de datos la observación de los videos subidos por los candidatos a la plataforma, revisando las principales características discursivas que estos poseían. Entre los principales hallazgos se evidencia que el alcance general es similar al de otras redes, además, a pesar de que las temáticas discursivas principales son asertivas, es poco probable definir con exactitud un tipo de discurso que resulte efectivo, pues cada video posee un alcance distinto.

Vehicular Communication using Balanced Centralized and Decentralized Cluster Heads
Authors: Iskandarani Mahmoud Zaki
Published: January 2022

A new approach to vehicular communication employing equal weights for distance and vehicular speed for centralized and decentralized communication is presented. The main objective of this work, which is to establish utilization expression and characteristics for an optimized balanced vehicular communication is achieved. The technique is based on analyzing effect of communication process (centralized, decentralized) on transmission efficiency and probability of failure. The analysis using utilization function, cluster head selection time, and end to end transmission time. The simulation and analysis concluded that the decentralization approach is more efficient compared to the centralized approach, so combination of both is proved to be effective. The work also uncovered the need for optimization of vehicular speed relative to transmission radius and use of zoning to effectively improve transmission efficiency. Mathematical models are presented that covers a critical relationship between probability of transmission failure, cluster head selection time and end to end delay. Also, an important mathematical expression that considers cluster head selection time and end to end delay and their effect on connection utilization is presented. The work proves that combined centralized and decentralized techniques using balanced weights approach is effective using dynamic weights selection algorithm that determines optimum weights for both used variables (distance, Vehicular speed).

HISTOLOGY AND CYTOLOGY OF SUGAR CANE MOSAIC
Authors: Cook Melville T.
Published: January 2022

1. The symptoms of mosaic are more conspicuous on actively growing than on slow growing plants; and on the new than on the old leaves of a diseased plant. 2. The light areas of a diseased leaf are slightly thinner than the green areas. 3. The green areas correspond in every way to the leaves from healthy plants of the same age and variety. 4. The cells in the light area of a diseased leaf are slightly less in size than those in the green areas. 5. Intracellular bodies were difficult to find but corresponded quite well with those reported by Kunkel. 6. The host nuclei were usually very much enlarged in the diseased tissues, especially in the tissues of the leaves. They were frequently very irregular in form and it was very difficult to find intracellular bodies associated with them. 7. The chloroplasts were smaller and fewer in number in the mosaic than in the healthy tissues. 8. The internal cavities in both stems and leaves start with a disintegration of the cell walls.
A Review on Various Biofuels and its Applications

Biofuels derived from biofuels, plant or algae or animal wastes. Unlike fossil fuels such as petroleum, coal and natural gas, refilled immediately. Biofuels are fuels made from recently harvested plants. They act like fossil fuels: they burn when ignited, releasing energy that can be converted into kinetic energy in a car, or heat a home. Biofuels can be obtained from a variety of crops and from a wide range of plant products from other industries. Not only is biodiesel stable, it is also a highly environmentally friendly, clean burning option that can be used without modification in diesel engines. In fact, biodiesel reduces greenhouse gas emissions by 56% to 86%, which means that the use of biodiesel has already reduced carbon emissions by 75.5 million metric tons. Many countries promote the use of biodiesel. In 2001, global biodiesel consumption was approximately 0.3 billion gallons. Based on the raw material, biofuels are divided into four groups: third, fourth (FGBs), first biodiesel, which is the only is a locally produced, clean-burning, renewable alternative to petroleum diesel. The use of biodiesel as a vehicle fuel enhances energy conservation, improves air quality and the environment, and provides safety benefits. Biofuels are transport fuels such as ethanol and biomass based diesel fuels. These fuels are usually blended with petroleum fuels (petrol and distillation / diesel fuel and heating oil), but can also be used on their own. Scientists have found that, in practice, biofuels produced from agricultural crops cause less pollution and greenhouse gas emissions than conventional fossil fuels, causing some environmental problems. Biofuels can also affect the poor. Various problems arise due to high prices for crops. It can go from improved water quality to creating new jobs in economically backward areas. Some applications of bioenergy require a feed based on residues from dedicated field production (such as energy crops) or agricultural production. However, many plant species grown for biofuels release higher levels of the ozone precursor isoprene than conventional crops and plants. Excess ozone poses a well-documented risk to human health, with 22,000 premature deaths each year linked to ground ozone exposure in Europe.
Geopolitics in the Western hemisphere after Trump: Has the united states abandoned hegemony in Latin America?
Authors: Grass Kacper
Published: January 2022

The isolationist presidency of Donald Trump was only the last, albeit the most radical, of a series of United States administrations that have largely ignored fostering close relations with Latin America and the Caribbean. This apparent withdrawal has resulted in the steady rise of Brazil as a significant regional power as well as the incursion of Russian and Chinese influence in the region. In light of these developments, this article presents a historical overview of United States hegemony in the western hemisphere before outlining how recent setbacks have undermined this trend in the areas of regional trade, diplomacy, and security. As the Biden administration makes its transition, the article finishes by proposing how the United States could regain influence in the region by collaborating with its southern neighbors to promote economic development, defend human rights, and confront the region’s ongoing security issues.
Cinismo político. Un nuevo estilo discursivo en las democracias liberales
Authors: López de Lizaga José Luis
Published: January 2022

Este artículo parte de la premisa de que en las democracias liberales actuales se extiende un nuevo estilo discursivo propiamente cínico. El artículo traza una genealogía de este cinismo político partiendo del liberalismo político de John Rawls y recalando en la teoría agonística de la democracia de Chantal Mouffe, e intenta mostrar que la superación del liberalismo político que la teoría agonística lleva años proponiendo parece realizarse finalmente a través del cinismo, aunque con resultados diferentes de los esperados: la expansión del cinismo en la esfera pública debe entenderse como una degradación del debate público con consecuencias políticas inquietantes.
