This paper continues previous studies on designing stabilizing control laws for a mechanical system consisting of a wheel and a pendulum suspended on its axis. The control objective is to simultaneously stabilize the vertical position of the pendulum and a given position of the wheel. The difficulty of this problem is that the same control is used to achieve two targets, i.e., stabilize the pendulum angle and the wheel rotation angle. Previously, the output feedback linearization method was applied to this problem. The sum of the pendulum angle and the wheel rotation angle was taken as the output. For the closed loop system to be not only asymptotically stable in the output but also to have asymptotically stable zero dynamics, a dissipative term was added to the output-stabilizing control law. Below, a two-parameter modification of this law is described. Along with the dissipative term, we introduce a positive factor. The more general parameterization allows stabilizing this system in the cases where the control law proposed previously appeared ineffective. The properties of the new control law are investigated, and the attraction domain is estimated. The estimation procedure is reduced to checking the feasibility of linear matrix inequalities.
On the Transformation of a Stationary Fuzzy Random Process by a Linear Dynamic System

Published: June 2024

In this paper, stationary random processes with fuzzy states are studied. The properties of their numerical characteristics—fuzzy expectations, expectations, and covariance functions—are established. The spectral representation of the covariance function, the generalized Wiener–Khinchin theorem, is proved. The main attention is paid to the problem of transforming a stationary fuzzy random process (signal) by a linear dynamic system. Explicitform relationships are obtained for the fuzzy expectations (and expectations) of input and output stationary fuzzy random processes. An algorithm is developed and justified to calculate the covariance function of a stationary fuzzy random process at the output of a linear dynamic system from the covariance function of a stationary input fuzzy random process. The results rest on the properties of fuzzy random variables and numerical random processes. Triangular fuzzy random processes are considered as examples.
Big river channel formation and deformation in the intermountain basin (case study of the Yana River within the Kular mountain massif)
Authors: Shkolnyi D. I. , Chalov R. S.
Published: June 2024

The incised pebble-boulder channels of large mountain rivers (including the Yana in its mountainous area), their morphology and history of formation are well studied. However, local conditions within the intermountain depressions lead to the emergence of specific features of the channel development and its morphology — in this case, the formation of finger-shaped meander. The paper analyzes the historical and modern features of the formation of the Yana riverbed in the “Porogi” section located in the depression inside Kular range, and describes the negative impact of channel processes on navigation. Using this case study, we consider the characteristic features of the channel development of a large river under the influence of a complex of factors — the regional geological conditions (which caused active incision of the channel), discharge, and channel sediment composition. Characteristics of lateral migration and curvature development of meander controlled by bedrock and narrowing of the valley are presented. The discharge conditions under which the displacement of riffles is possible are calculated. The forecast of the further channel development and recommendations for sustainable navigation are given.

The chronology of the Mikulino Interglacial and its individual phases have been the subject of discussion. The goal of this study was to evaluate the time limits of the main stages of the Mikulino Interglacial on the Russian Plain according to ²³⁰Th/U dating and paleobotanical studies of lake and peat sediments from the known sections located within the Tver region on the Bolshaya Dubenka River, Malaya Kosha River, Granichnaya River, and Sizhina River (“Kileshino-2” section). An improved geochronological approach has been applied to identify layers suitable for the ²³⁰Th/U isochronous approximation. In combination with pollen and carpological studies of the deposits, this made it possible to date units corresponding to relatively narrow time intervals in the development of plant formations at different stages of the Last Interglacial. New paleobotanical studies of buried lake and peat sediments from the sections located on the Bolshaya Dubenka River, Malaya Kosha River, and Granichnaya River allowed us to restore the vegetation development during the Mikulino Interglacial in the interval of pollen zones M1–M7, i.e., more pollen zones have been analyzed and in greater detail than in 1960–1970. A chronological scheme of the main stages of vegetation development in the Mikulino Interglacial is proposed based on the results of ²³⁰Th/U dating and paleobotanical studies of organic-rich deposits from the Tver region sections in combination with previously published data obtained for the “Nizhnyaya Boyarshchina” section from the Smolensk region. The Mikulino Interglacial had begun about 130–126 kyr ago. Its first phase, corresponding to the M2 zone, ended ca. 118 kyr ago. The pre-optimal stages of vegetation development (M3 and M4 zones) fit into the time range of ca. 118–112 kyr ago. The climatic optimum of the interglacial (M5 and M6 zones) began ca. 112 kyr ago and ended ca. 100 kyr ago. The duration of the Mikulino Interglacial was probably at least 25 thousand years.
The influence of a weak ultra-low
frequency electromagnetic field 2 and 8 Hz
on the consolidation of daytime sleep
Authors: Ligun N. V.
Published: June 2024

The article present the hypothesis that weak electromagnetic fields
of ultra-low frequencies (0.5–26 Hz) could affect daytime sleep features and
structure. Parameters of daytime sleep continuity were compared in the study
with counterbalanced control/exposition (50 min exposure to electromagnetic
field at 2 and 8 Hz / 0.004 μT) scheme in 14 healthy volunteers (8 men,
6 women, mean age 19.43 ± 1.22 y.o.). Nonlinear regression model was used
to assess daytime sleep continuity. Exposure to a weak electromagnetic field
of ultra-low frequency significantly improved the quality of sleep, assessed
by the indicator of sleep continuity, namely, there were fewer transitions
from the second and deeper stages of sleep to the first stage and to the state of wakefulness. The results can be used to develop non-pharmacological
methods of sleep correction, as well as to improve the quality of short-term
sleep and its positive effect on wellbeing, cognitive function and working
capacity

Authors: Dhiaulhaq Mudrikah , Utami Tri , Nabila Akifah Noor Ayu
Published: June 2024

This study aims to improve cognitive abilities through patterned beading activities using loose parts in children aged 4-5 years. This research employs Classroom Action Research (CAR). The study was conducted in two cycles, each comprising four stages: planning, implementation, observation, and reflection. Data collection techniques used in this research include observation, interviews, performance assessments, and documentation. The results show that learning activities aimed at enhancing cognitive abilities through patterned beading with loose parts can effectively improve cognitive skills in recognizing patterns, particularly ABC-ABC patterns. The improvement is evident as the pre-cycle activities showed that the percentage of pattern recognition skills in the BSH and BSB categories was only 14.28%. In Cycle I, this increased to 50% in the BSH and BSB categories. Subsequently, in Cycle II, cognitive abilities in pattern recognition within the BSH and BSB categories further increased to 78.57%. These findings imply that incorporating loose parts in patterned beading activities can be a valuable strategy in early childhood education to enhance cognitive development.

This assistance was carried out as an effort to help the Koperasi Karyawan Jayawijaya PT KPI, Timika Regency, Papua. The cooperative is currently facing the problem of large amounts of account receivables, which since 2018 have not been able to be collected. The method used to resolve these problems was a participatory mentoring approach, starting with preparation and planning, implementation and evaluation. Until now, only two stages of activities have been carried out, for evaluation we are still waiting for the decision of the member meeting which will be held in March 2024. As a result of the assistance, it was agreed that the cooperative can write off problematic business receivables by writing them off completely at the end of the 2024 financial year or gradually over five (5) years, depending on the decision in the RAT. In the future, cooperatives need to anticipate by making provisions to form reserves (allowance).
Bimbingan Teknis Penyusunan Anggaran Operasional Koperasi Simpan Pinjam dan Koperasi Konsumen Bagi Pengurus Koperasi di Jawa Barat

Published: June 2024

Professional business management includes, among other things, implementing management functions correctly and precisely. One of the fundamental management functions is preparing rational, detailed, and measurable planning. For this reason, all cooperative managers must be able to prepare plans, both work program plans and financial plans to implement the work program, which is often called the cooperative income and expense budget. This reason is one of the reasons for providing technical guidance carried out by the West Java Province Cooperative Education and Training Center with material including the preparation of the Cooperative Work Plan and Revenue and Expenditure Budget (RKAPBK). The work plan is prepared according to the type of cooperative activity, which in this case is consumer cooperatives and savings and loan cooperatives. If the cooperative has activities related to the financial services business, then all management, including the preparation of the RKAPBK, must be made separately. This is absolutely necessary because financial services businesses are financial sector businesses and trading businesses are real sector business activities. In the financial services business of savings and loan cooperatives, money is a product whose benefits are taken, which will generate income over time. Meanwhile, in the real business sector, the products being traded are goods and money is the means of payment. For this reason, in this technical guidance, the RKAPBK case for financial sector businesses in Savings and Loans Cooperatives and the RKAPK case for the real sector business of Consumer Cooperatives are discussed.

Acceso al significado literal y figurado de formas léxicas ambiguas por hablantes de inglés LE
Authors:   Universidad Autónoma de Queretaro, Castro Yáñez Sonny Angelo
Published: June 2024

En inglés, las partículas verbales (phrasal verbs) y las configuraciones verbo + preposición comparten una superficie común, pero despliegan rasgos sintácticos y semánticos distintos en formas léxicas ambiguas (eat up). El estudio cómo los hablantes no nativos de inglés LE procesan el significado de formas léxicas ambiguas que pueden asignárseles un significado literal o figurado, es decir si se accede primero al significado de partícula verbal, o al significado de verbo + preposición. Además, se busca evidenciar el efecto del nivel de proficiencia en el procesamiento de dichas construcciones ambiguas. Estudios previos (Matlock & Heredia, 2002), han demostrado evidencia de la influencia en el tipo de bilingüismo en el acceso a significados literales o ambiguos en formas léxicas ambiguas. Los participantes son dos grupos de hablantes mexicanos de inglés LE con nivel de proficiencia avanzado e intermedio. Los resultados obtenidos a través de la prueba ANDEVA permiten demostrar que en el proceso de desambiguación de formas léxicas ambiguas, el nivel de proficiencia no es una variable que permita una preferencia significativa por una interpretación literal o figurada. Ambos grupos acceden al mismo tiempo a significados de verbo + preposición y de partícula verbal, es decir se seleccionan ambas interpretaciones sin mostrar preferencia por uno de los significados. El estudio es relevante para el entendimiento de cómo se accede al significado literal y figurado en el lexicón de hablantes bilingües de acuerdo a teorías del procesamiento léxico.

‘‘‘...pausa… continuación? (a Zelter, 26 de marzo de 1816)’’. La danza de la vacilación. La ladrona de fruta de Peter Handke
Authors:   Universität Zürich, Wagner Karl
Published: June 2024

La “última epopeya” de Peter Handke, “La ladrona de fruta”, según la tesis, amplía y renueva las formas lúdicas de la narración y las características de las formas de la gran epopeya mediante el recurso a los antiguos relatos de todas las partes del mundo. La narración sin trama, sin héroes, explora las posibilidades de la contemplación, la reflexión y la autoironía. Las aventuras de la vita contemplativa y la atención a lo discreto se escenifican con tanta delicadeza como fragilidad, entre otras cosas mediante una relectura de Goethe.
“Yo sola soy tres caminantes” De la triple narración “adaptada libremente de Wolfram von Eschenbach” en La ladrona de fruta de Peter Handke
Authors:   Universität Wien, Pektor Katharina
Published: June 2024

Este ensayo pretende llevar a cabo una lectura detallada de una imagen del texto épico de Peter Handke del año 2017 La ladrona de fruta o viaje de ida al interior del país: en ella, Alexia, la heroína de la historia, es acompañada en parte de su viaje por un perro que lleva un cuervo en la boca; ambos animales simbolizan diferentes aspectos de la narración. Alexia aleja al perro y se libera con las palabras: “Yo sola soy tres caminantes” dice a la narradora y sigue al cuervo. La frase de Alexia es una alusión a Wolfram von Eschenbach, que en su prólogo de Parzival se adjudicó a sí mismo como narrador, con las palabras “ahora déjame ser un tres”, la imagen de la Trinidad divina. Handke desarrolla esta Trinidad para su narrador al principio de su La ladrona de fruta, lo que es retomado en la imagen del perro y el cuervo. El autor interpreta esta imagen y muestra cómo pequeños fragmentos de texto contienen ya toda la poética del autor, cómo la desarrollan y aplican. Lo anterior, a través del estilo narrativo de Handke, variado, simbólico y autorreferencial, que alude a sus propios textos y a los de otros.
Identifying with Disability: Benefit or Barrier? A Three-Part Study Examining the Impact of Disability on Over-Qualification, Access to Work-Related Training, and Inclusion in University Classrooms
Authors: Emanuel Talia
Published: June 2024

Despite Canada's commitment against discrimination, workers with disabilities face barriers to labour market participation. Relying on Human Capital Theory, Signaling Theory, and Stigma theory, this three-part study examines impact of disability status in three distinct contexts. Study 1 explores the relationship between disability status and job-qualification mismatches in a representative sample of 7172 respondents from Statistics Canada's General Social Survey (GSS) data bases. Disability status is negatively corelated with horizontal job education match, and positively corelated with perceptions of under-qualification. Study 2 explores the relationship between disability status and work-related training using a series of logistic regressions, and a GSS sample of n =7, 154. Disability status is negatively corelated with the probability of receiving employer-sponsored training. Study 3 tests the impact of disclosing disability related information university project team inclusion decisions. Using a sample of 378 TMU students, Study 3 found that signaling diabetes had no main effect on inclusion ratings, but diabetes-related stigma negatively predicted the inclusion of those with diabetes. Taken together, these studies failed to prove disability status as a consistent disadvantage. Instead, unanticipated results suggest a more complex relationship between disability status and labour market outcomes. I discuss the implications of these findings and suggest directions for future research.
Academic Independent Director Resignation and Stock Price Crash Risk: Evidence From China
Authors: Xu Beijia
Published: June 2024

Academic independent directors typically reduce future stock crash risk by improving the quality of financial reporting, urging corporate social responsibility, discouraging overinvestment, and reducing institutional capital. Accordingly, this paper analyzes the impact of academic independent director resignations on firm-specific stock price crash risk under the influence of Document 18 and Regulation 11 using data from the Chinese stock market from 2008 to 2018. During the research period, the paper further investigates the PSM-DID method and uses the methodology to test the policy effects. Heterogeneity tests show that academic independent directors with a doctorate degree (Ph.D.) and female academic independent directors have a more significant impact on stock price crashes. In contrast, in the overall sample, the relationship between academic director resignations and stock price crashes was concluded to be less significant and passed multiple robust tests. Overall, our findings suggest that some kind of academic independent directors in China provide value to firms and help reduce stock price risk, effectively bridging the limitations of the literature in its development.
Canadian SME Internationalization to the UAE: A Case Study Through a Network-based Lens
Authors: Qutob Anas
Published: June 2024

Canadian small-and-medium enterprises (SMEs) can enhance their chances for success through access to potentially lucrative foreign markets and have commonly relied on network ties to facilitate overseas expansion. However, relying heavily on network ties to enter such markets may hinder expansion when geographical distance is great, and boundaries of network connections are reached since information borne out of those networks may lack objectivity and create distorted images of reality, suggesting that network-based explanations are overstated in the existing literature. The role of network ties is salient with immigrant-owned internationalizing SMEs whereby shortfalls in firm resources are offset by network links to host markets. Nevertheless, Canadian SMEs with native-born owners with no inherent ties have succeeded in expanding into such markets. Therefore, how exactly do such SMEs expand into geographically and culturally distant markets without pre-existing network ties? A case study of 6 Canadian SMEs with owners who have either expanded into or plan expansion into the United Arab Emirates, a culturally and geographically distant market, despite possessing no pre-existing ties. Results reveal that these firms have navigated the uncertainties of expanding into distant markets with little or no pre-existing network ties through early-stage network broadening activities and outsourcing networking activities to domestic market experts.
Indirect Positive Effects of the COVID-19 Pandemic on Air Pollution in Canadian CMAs/CAs
Authors: Damba Nelson
Published: June 2024

This paper investigated how the restrictions during the COVID-19 pandemic have affected air pollution within Canadian Census Metropolitan Areas/Census Agglomerations (CMAs/CAs) and provinces/territories in 2020 compared to 2019 (pre-pandemic). It explored the connection based on emission levels of two air pollutants (NO and PM ) obtained from the National Air Pollution 2 2.5 Surveillance Program (NAPS) website, pandemic restrictions in Canadian cities obtained from COVID19 Government Measures Dataset, and socio-demographic factors from the 2016 Census which are the pollutants causes. This secondary data compiled in Excel database was used within multiple analyses which included, descriptives, pairwise t-test, correlation, stepwise regression done in SPSS, and using GIS methods to map the final results. The results showed a reduction in NO emi2sions in many CMAs/CAs and provinces, but increased PM emiss2.5s in 31 CMAs/CAs and 8 provinces. Reductions in NO 2nd PM wer2.5ost prominent in March and April of 2020 when the most stringent COVID-19 restrictions were implemented. The overall results showed a small but significant connection between the air pollutants and the few socio-demographic variables chosen through the stepwise technique (i.e. commuting time, public transit, and work location) contributed to the connection. These results corroborate findings from previous studies on air pollution and mobility restrictions and indicate that strategies such as remote work, and conversion to environmentally friendly modes of transportation (hybrid vehicles) can be leveraged to reducing NO and PM emissions in the future. These strategies 2 2.5 could especially be beneficial to the provinces and CMAs/CAs with high PM emissi2.5. Lack of data limited how thorough the analysis of the topic could be conducted.
Gaze: A Digital Tool Designed for the LGBTQ+ Community to Confidently Navigate and Interact in Public Spaces
Authors: Pinto Tyra
Published: June 2024

Members of the LGBTQ+ community are often on the lookout for spaces where they can freely express themselves without fear. These spaces include LGBTQ+ inclusive businesses, events, community centres, and organizations that are active advocates all year round towards a framework that supports equity, diversity, accessibility, and inclusion. Many people in the community operate from a scarcity mindset. It is a mindset that stems from the lack of spaces and the inaccessibility and difficulty of finding these spaces. This research paper and creative artefact, Gaze, focuses on promoting safe and inclusive spaces catered to Toronto's LGBTQ+ population, making them easier to identify and navigate. Toronto is home to Canada's largest LGBTQ+ population, and throughout the year, this community celebrates its creativity and diversity through various organizations and events. The creative artefact, Gaze, proposes to design a mobile application that combines services relative to digital directories, social media networks, and wayfinding technology. The goal is to enable the LGBTQ+ community to confidently navigate and interact in public spaces that prioritize their safety and embrace and empower those entrepreneurs who create them. With Gaze, there is potential to reflect the true diversity of Toronto's frequently overlooked LGBTQ+ population.
Study of Problems Involving Mobile Agents
Authors: Kundu Somnath
Published: June 2024

In this thesis we study two different problems that involve the movement of some entities within a well-defined space. One problem is in a continuous domain and the other problem is in the context of discrete spaces of graphs. 

The first problem is a primitive vehicle routing-type problem in which a fleet of n ∈ {1, 2, 3} unit speed robots start from a point within a non-obtuse triangle ∆, where the goal is to design robots’ trajectories to visit all edges of the triangle with the smallest visitation time makespan. Here, makespan is defined as the maximum of the times needed by each robot to finish the work. We begin our study by introducing a framework for subdividing ∆ into regions with respect to the type of optimal trajectories that each starting point P ∈ ∆ admits, pertaining to the order that edges are visited and to how the cost of the minimum makespan Rn(P) is determined, for n ∈ {1, 2, 3}. These subdivisions lead to our main result, which involves makespan trade-offs with respect to the size of the fleet. 

In the next problem we study unit acquisition process in the context of random graphs. Here each vertex of a given graph has unit weight initially. In each step, the unit weight from a vertex u to a neighbouring vertex v can be moved, provided that the weight on v is at least as large as the weight on u. The unit acquisition number of graph G, denoted by au(G), is the minimum cardinality of the set of vertices with positive weight at the end of the process, over all acquisition algorithms. We investigate the Erdõs-Rényi random graph process and show that asymptotically almost surely au(G) = 1 when the random graph process creates a connected graph. The result holds in the strongest possible sense, since au(G) ≥ 2 if the graph is disconnected.
Identity Information in Object-Level Descriptions: Towards Inclusive Cataloguing Contemporary Photography
Authors: Kanellopoulos Maria
Published: June 2024

This research follows an epistemological questioning among archival practitioners who are challenging methods of historical recordkeeping. The National Gallery of Canada’s contemporary photography holdings serve as a case study to question what information is deemed necessary in records documentation and the ways that information reaches the archive. I propose including self-disclosed object-maker identity information in museum databases to better contextualize, and enable the interpretation of collection objects and allow more accurate representation of artists and makers. Self-disclosed identity information shifts knowledge production away from the institution to the object-maker, decentering information and power structures away from collecting institutions. This study presents the Inclusive Cataloguing Toolkit as a practical solution. Its creation and implementation is inspired by contemporary archival documentation practices such as participatory description, archival autonomy, and record co-creation that relocate information, knowledge, and power structures to bridge the needs of inclusive cataloguing and provide a framework for future change.
Genetic variation of heat tolerance in a model ectotherm: an approach using thermal death time curves

Published: June 2024

The assessment of thermal tolerance holds significant importance in predicting the physiological responses of ectotherms, particularly in elucidating their capacity for evolutionary adaptation in the context of global warming. Current approaches to assessing thermal tolerance have limitations that can lead to misleading results, especially with regard to the heritability of thermal limits. In this study, we examined twenty isogenic lines of Drosophila melanogaster from the DGRP panel to characterize their thermal death time (TDT) curves, which account for the duration and intensity of heat stress. Furthermore, we examined the extent of genetic variation in the two parameters that characterize TDT curves, namely CTmax and thermal sensitivity z. Our analysis revealed evidence of genetic (co)variation for both parameters. Results from simulations of the evolutionary consequences of selection on CTmax and z suggest that directional selection to increase CTmax will also increase z as a correlated response. However, directional selection to increase z may have the opposite effect. We conclude that the evolution of thermosensitive or thermotolerant strategies is better achieved by directional selection to decrease or increase CTmax, which may aid in mitigating the effects of global warming on ectotherms.

Published: June 2024

This chapter presents the rationale behind employing the term ‘EU peripheries’ in the book and clarifies the theoretical framework adopted to define this term within the context of the EU integration process. The first section scrutinizes the concept of ‘EU peripheries’ as it will be theorized in the book. Its main aim is to critically examine the evolving connotations of the term, particularly in light of several crises of the last decade. Subsequently the chapter delves into the diverse manifestations of emerging forms of EU contestation at the peripheries, followed by the methodology section and an outline of the book’s structure. In the last section we examine the selected country cases and their contribution to the proposed conceptualization of EU peripheries, drawing connections with existing literature on the subject from a multi-disciplinary perspective. Finally, the chapter outlines the unique aspects of our approach and its potential contributions to existing scholarship in this field.
From Dreaming of to Dealing with Europe: How the Political Elite in Georgia Frames and Contests the EU
Authors: Aprasidze David
Published: June 2024

How do Georgian political elites frame the EU and EU integration in their discourse? Why do they simultaneously support and contest the EU? How does the membership perspective recently opened for Georgia alter this discourse and contestation? In this chapter, we argue that the EU became the cornerstone of domestic political struggle in Georgia. Local elites regard the EU and EU integration as a strategic process, producing new opportunities and challenges. They contextualize events related to the EU and EU integration through the lenses of their interests and expectations. This reveals the limits of the EU’s transformative power, and therefore conditionality, even within the membership perspective, especially in the liminal periphery with competing forces such as Russia. Along with secondary data regarding Georgia–EU relations, the chapter draws on original interviews with members of the Georgian parliament, both from the ruling party and the opposition, and their public statements.
THE DEVELOPMENT AND INITIAL TESTS FOR THE PSYCHOMETRIC PROPERTIES OF THE EQUAL OPPORTUNITY IN EDUCATION SCALE
Authors: Gül Yavuz Ercan , Yeşil Rüştü
Published: June 2024

Although equality of opportunity in education is a current and important issue, most of the studies on this subject are based on theoretical studies rather than empirical studies. The main reason for this can be said to be the lack of a valid and reliable measurement tool in this field. For this reason, this study aims to develop a valid and reliable measurement tool for determining pre-service teachers' perceptions of equality of opportunity in education. For this purpose, data were collected from four different samples using a simple random sampling technique. First, a literature review was conducted, and qualitative interviews were conducted with the first sample on equal opportunities in qualitative education. After the item pool was created, the first application was made in order to determine the factor structure of the measurement tool. Data were collected from a separate sample to test the resulting structure and perform confirmatory factor analysis. Then, in the context of reliability studies of the measurement tool, calculation of the internal consistency coefficient, extracted mean variance, composite reliability and test-retest processes were used. As a result, a valid and reliable scale for determining the perception of equality of opportunity in education consisting of three factors and 23 items has been brought to the education literature.

IDENTIFYING AND VALIDATING SUSTAINABLE DEVELOPMENT GOALS-RELATED KEY COMPETENCIES IN UNDERGRADUATE GRAPHIC DESIGN EDUCATION
Authors: Le Quyen Tran Thi , Liou Shyhnan , Yang Chia Han
Published: June 2024

In contemporary higher education, aligning student competencies with sustainable development goals (SDGs) is crucial for enhancing their employability. This necessity extends to graphic design undergraduate programs, pivotal in nurturing designers capable of addressing global sustainability challenges. Using a mixed-methods approach, this study aims to outline essential competencies for graphic design undergraduates pertinent to the SDGs. The research commenced with a systematic review of fourteen seminal articles, leading to the initial identification of fifty-eight key competencies. Subsequently, a Delphi study involving 44 graphic design experts validated these competencies. This iterative process refined the list, excluding twenty-seven competencies and affirming thirty one as critical. These validated competencies were categorized into four groups: Systemic, Performance, Contextual, and Global. The study's findings provide valuable insights for graphic design educators and industry employers, illuminating competencies essential for addressing sustainability challenges. Furthermore, this research contributes to academic discourse by offering a structured framework for integrating SDG-related competencies into graphic design education. This facilitates the development of designers proficient not only in their craft but also in sustainability imperatives. Our aim is to enhance pedagogical strategies and inform curriculum development in graphic design education, aligning them with evolving professional demands and sustainable development objectives.

Authors: Torres Rodas Tiberio
Published: June 2024

En el presente trabajo se presenta un análisis de las disposiciones de la Constitución de la República del Ecuador vigente desde el año 2008, y que se relacionan con el régimen tributario nacional. Se inicia con una referencia breve a la concepción del Estado en función de la noción del Buen Vivir y la obligación ciudadana de contribuir al sostenimiento del gasto público. Se estudian luego los principios constitucionales rectores de la actividad tributaria y los aspectos extrafiscales del tributo y del régimen tributario en atención a la concepción del Estado como garante de derechos. Finalmente, se hace una muy breve descripción del ejercicio de la potestad tributaria del Estado, con relación a los distintos tipos de tributos.
