DIGITAL BUSINESS MODEL OF AN ENTERPRISE IN AN INNOVATIVE ECOSYSTEM: INTEGRATION CONCEPT TAKING INTO ACCOUNT THE TECHNOLOGICAL PROFILE AND INDUSTRY SPECIFICITY
Authors: Galimova Margarita
Published: December 2024

The article is devoted to the development of a digital business model concept aimed at the effective integration of enterprises into innovative ecosystems in the context of dynamic technological changes and digital transformations. Traditional business models are poorly adapted to the new rules and features of the digital environment and become a competitive constraint that slows down innovation processes and restrains technological breakthroughs. The development of an adaptive digital business model is becoming relevant in the context of technological gaps and imbalances in industry potentials.
The author defines the principles of adaptation of digital business models of enterprises, taking into account the technological profiles of both the enterprises themselves and the ecosystems into which they are integrated. The technological profile is determined by the level of digitalization, innovative potential and the ability to interact, which allows enterprises to choose the most effective integration strategies.
Particular attention is paid to the analysis of integration models and trajectories taking into account the digital context. A matrix of management projections is proposed, which, based on an assessment of technological (including digital) gaps, identifies the positions of enterprises and integration models, such as incremental adaptation, technological convergence, integration reinforcement, cluster innovation leadership and others, which provide enterprises with flexibility in the context of digital transformation. Depending on the level of technological maturity and digital capabilities of enterprises and ecosystems, it is proposed to use digital frameworks such as business models of digital licensing, platform solutions, data sharing and analytics, cluster strategies and sustainable development, adapting them to changes in the technological environment. The implementation of these models allows enterprises not only to improve operational efficiency, but also to strengthen interaction with partners, which contributes to the development of innovative capabilities of the ecosystem, the activation of regional innovations and the achievement of a synergistic effect on the scale of the entire territory.

Published: December 2024

Digital transformation has become an essential tool for crisis management, allowing enterprises to adapt to changing conditions and effectively confront modern economic challenges. The integration of technologies such as cloud computing, big data analysis, artificial intelligence and process automation opens up new opportunities to increase efficiency, reduce costs and increase business sustainability. Companies actively implementing digital solutions not only minimize losses during crisis periods, but also strengthen their competitive positions. The study examines the impact of digitalization on the effectiveness of crisis management using both qualitative and quantitative analysis methods. The key performance indicators (KPIs) were the speed of decision-making, reduction of financial losses and adaptability of business processes. It has been revealed that real-time data analysis, crisis forecasting and the development of preventive measures have become possible thanks to digital tools. At the same time, significant gaps in the digitalization of certain industries, for example, in the mining industry (-61.7) and logistics (-52.8), emphasize the need for targeted investments in these sectors. Regional differences also have a significant impact on business sustainability. Thus, in the Krasnodar Territory, the liquidation rate of organizations decreased from 2.174 in 2021 to 1,800 in 2023, which indicates the effectiveness of anti-crisis measures. However, this figure remains one of the highest, which indicates the need for additional support measures. Thus, digitalization becomes an integral part of crisis management, creating conditions for innovative development and long-term sustainability. Effective planning, selection of a suitable business model and constant monitoring of the implementation of measures ensure the successful overcoming of crisis situations and strengthen the position of companies in the market.

Authors: Kuznetsova Svetlana , Kutepova Lyubov'
Published: December 2024

Transfer of innovations in inter-industry cooperation ensures a synergy effect. Inter-industry cooperation is of paramount importance today. Cooperation between residents of the industrial park is based on the organization of production chains. As a result of cooperation, the competencies of anchor residents are formed, and the quality of import substitution products increases, as well as stable demand for domestic products. As a result of the implementation of the mechanism of cooperative links, costs are reduced, the optimal production process and efficient loading of production capacity are ensured, and innovations are introduced. To implement cooperative links, it is advisable to involve a pool of management companies. The authors propose to intensify work on organizing the navigation of domestic industrial parks abroad. It is necessary to build industry chains when developing projects for joint international parks in other countries in order to create centers of technological cooperation with industry specialization. The central tasks set for industrial parks are the implementation of uninterrupted mutual deliveries of products, as well as the formation of agreements for organizing technological chains of foreign partners. The authors determine that the goal of implementing the ideas of cross-cutting inter-industry cooperation between industrial parks is to ensure qualitative changes in the dynamics of economic growth, technological development and global leadership of domestic products in the world market. The implementation of the idea of cross-cutting inter-industry cooperation of industrial parks will ensure technological sovereignty, which characterizes the political and economic independence of the country. Due to cooperation chains, industrial production is restored; manufacturers are provided with components and raw materials. The authors have defined the trajectory of development of industrial sites, the paths of associations, industrial consortiums, which have their own industry focus. The geography of technological cooperation has undergone fundamental transformations. It is necessary to form industrial and logistics infrastructure along the route of international transport corridors. The external direction of organizing points of presence of domestic production is being actively developed.

Authors: Batistuta Ahmad Isa Fitra Ikhwanda , Safitri Rini
Published: December 2024

This study aims to explore differences in employee productivity levels based on tenure, revealing that employees with less than three years of service generally exhibit lower productivity compared to their more seasoned counterparts. The research was conducted at PT Didu Indonesia, focusing specifically on a comparative analysis of productivity between employees with tenure under three years and those with tenure exceeding three years. Employing a quantitative research design, the study utilized secondary data, comprising productivity records from 60 employees categorized by tenure from 2021-2023. Data analysis was performed using SPSS, with the Kolmogorov Smirnov test yielding a statistic of 3.873 and an asymptotic significance (2-tailed) of 0.000. Since this result is below the 0.05 threshold, the null hypothesis (H0) was rejected in favor of the alternative hypothesis (H1), confirming that the productivity levels between the two groups are significantly different.
The implications of these findings are significant for human resource management and organizational strategies. The observable gap in productivity based on tenure suggests that companies should consider implementing tailored onboarding and mentorship programs for new employees to enhance their productivity more swiftly. Fostering a supportive work environment that facilitates skill development and knowledge transfer is crucial.
Moreover, identifies a need for ongoing training and professional development opportunities tailored to employees with varying levels of tenure. Organizations can ultimately benefit from recognizing the contributions of long-tenured employees, utilizing their experience as mentorship resources while investing in the growth of newer employees to bridge the productivity gap. By addressing these dynamics, PT Didu Indonesia and similar organizations can create a more cohesive, productive workforce that enhances overall organizational performance and job satisfaction.

Ontslag tijdens pensioentransitie; de verborgen valkuilen van de Wet toekomst pensioenen

Met de inwerkingtreding van de Wet toekomst pensioenen (Wtp) per 1 juli 2023 worden de aandachtspunten bij ontslag verder uitgebreid. Bij ontslag van een werknemer verdient het aanbeveling voor werkgevers en betrokken juristen om niet alleen te kijken naar de reguliere gevolgen van dat ontslag, maar tevens naar de specifieke transitiemaatregelen bij de pensioenuitvoerder in het kader van de wijziging van de pensioenregeling als gevolg van de Wtp. Een aanpassing van de ontslagdatum kan onder omstandigheden een compensatie voor de overgang naar het nieuwe pensioenstelsel veiligstellen.
Measuring Adolf Loos’ Parallax: Retroactive Photogrammetry and the Persistent Off-Screen
Authors: Pearce Thomas
Published: December 2024

This article traces the ever-shifting and often contradictory nature of what it calls Adolf Loos’ architectural parallax. Parallax, the effect whereby an object’s position appears to differ when viewed from different positions, is suggested to encapsulate a key quality of experiencing Loos’ spatial compositions. Centrally, the article uses a set of 1901 photograph capturing the parallactic qualities of a Loos-designed, mirror-lined Viennese tailor shop as an unintended source for its digital photogrammetric reconstruction. The photographic evocation of Loos’ architecture’s immeasurability is turned against itself and misused to take its measure. The resulting three-dimensional point-cloud model recuperates the enigmatic shop’s geometry as well as the position of the photograph’s carefully staged protagonists. Yet the photogrammetric reconstruction also prompts the emergence of new elements of the immeasurable. It is this persistent off-screen, this ongoing personal/photographic/architectural reference to a difficult-to-grasp ‘Other’ that is finally proposed to constitute an expanded understanding of Loos’ parallax.

«Sin otro pleto e sin otro enxeco»: estructuras léxicas y variación en documentación temprana del castellano norteño
Authors: Ramos Remedios Emiliana
Published: December 2024

Pese a responder a la necesidad de precisión semántica propia de esta tradición discursiva y pese a su carácter relativamente fijo y repetitivo, las estructuras propias de la documentación notarial en las que se organiza parte de su léxico —series, dobletes, binomios o lexías complejas—son útiles para discernir la variación, sea estilística, cronológica o geográfica, como intentaremos mostrar a partir de la documentación castellanonorteña del corpus CORHEN. Así, el léxico incluido en estas estructuras puede reflejar variación diatópica o preferencias escriturarias, como sucede con la voz corte, o mostrar procedimientos de variación y cambio lexicosemántico, como el proceso de especialización a lo largo del siglo xiii de la voz polisémica pleito desde ‘acuerdo’ a ‘litigio’, mientras se impone sobre paralelos semánticos como enjeco.

Desarrollo de habilidades argumentativas a través de una Unidad Didáctica en la Formación Inicial de docentes de Física
Authors: Campos Moncada Gonzalo
Published: December 2024

La argumentación científica es crucial en la construcción y evaluación del conocimiento científico, y tiene un gran potencial en la educación. Sin embargo, no se proveen de oportunidades sistemáticas para desarrollar la habilidad en los estudiantes, por la falta de formación docente. Esta investigación busca evaluar el impacto de una Unidad Didáctica en la habilidad argumentativa de estudiantes de Pedagogía en Física y sus percepciones sobre la argumentación en ciencias, utilizando una metodología mixta. Se realizó una intervención en un curso de Mecánica de primer año en una universidad pública de Santiago de Chile. Los resultados muestran que, aunque los futuros docentes demuestran un alto manejo conceptual, tienen dificultades para articular evidencias y justificaciones en sus conclusiones. Aunque comprenden mejor la importancia de argumentar en ciencias, no se observó una mejora significativa en su habilidad argumentativa. Sin duda que, en la medida que se continúe explorando y promoviendo este tipo de instancias, se podrán establecer bases más sólidas para la formación de futuros docentes de Física en argumentación científica.

Identificación de los sistemas físicos en el estudio de procesos energéticos en libros universitarios de Física
Authors: Zang Claudia , Giacosa Norah
Published: December 2024

Se realizó la inspección de diez libros de texto universitarios usados en Argentina, mediante técnicas de análisis de contenido, con el propósito de describir si se explicitan los sistemas de interés en el desarrollo teórico de los conceptos energía, trabajo, teorema de trabajo-energía cinética y conservación de la energía. Se encontró que en una fracción importante de textos se deslizan frases que podrían reforzar conceptualizaciones inadecuadas como asignar energía a objetos individuales. Además, en la mayoría de ellos se destina poco espacio a la explicitación de los sistemas subyacentes y la identificación de las interacciones que éstos tienen con su entorno. Esto podría dificultar la comprensión por parte de los estudiantes de que el tipo de energía presente en el sistema está condicionado por la elección que se realiza del mismo.

El potencial de la inclusión de múltiples representaciones de conceptos físicos ha mostrado ser beneficioso para alcanzar una mayor significación y comprensión en contextos de resolución de problema. Este trabajo presenta un análisis parcial del estudio de los principios programáticos de construcción de conocimiento acumulativo en un contexto de enseñanza remota en una clase de física de quinto año de educación secundaria, que integra problemas con diagramas P-V. La dimensión semántica de la Teoría de los códigos de legitimación proporcionó herramientas de análisis multidimensionales que permitieron reconocer el valor de diversas estrategias de resolución y de contenido para identificar cómo se forman, organizan y validan los significados en el aula.
Kantian Transcendental Idealism in Physics Teaching: The Universe on a Sheet of Paper

Published: December 2024

One of the most attractive aspects of Theoretical Physics is that its implications are often more fascinating than ﬁction. Both Philosophy and Physics often use logical reasoning that involves experiments that cannot be carried out in practice, but that through imagination allow us to explore and understand non-experimental aspects of the Universe. Einstein popularized the term “thought experiment” for conceptual approaches explored only in the ﬁeld of ideas. In this work, we discuss how knowledge is possible through reﬂections that lead the subject from a simple logic to a transcendental logic from Kantian Transcendental Idealism. Subsequently, we present an initially simple experiment to be carried out in practice, involving folding a sheet of paper. Then, after verifying the existence of an experimental limit for its continuity, we performed it through a theoretical-mental extension and proceeded in a guided way to explore the Universe.
Lata falante: protótipo didático de transmissor eletromagnético com microfone piezoelétrico
Authors: Desteffani Admiral Tiago
Published: December 2024

Este artigo descreve a construção, e a aplicação em sala de aula, de um protótipo experimental, de baixo custo, que converte ondas mecânicas em ondas eletromagnéticas, e as transmite de forma que podem ser captadas por um aparelho de rádio. O protótipo foi desenvolvido a partir de materiais alguns materiais reciclados e utiliza-se de um transdutor piezoelétrico como atuador principal no alto falante. O protótipo, entre outros experimentos, foi utilizado em uma intervenção numa turma de alunos do sexto e sétimo ano de uma escola pública estadual, nas aulas de uma disciplina eletiva de robótica. A intervenção se fundamentou na perspectiva da experimentação investigativa, e na negociação de significados, em que os conceitos e seus significados são compartilhados ao longo da intervenção. Como resultados obtidos destacou-se a praticidade e funcionalidade do protótipo e, em relação aos resultados de aprendizagem, verificou-se indícios claros de aprendizagem significativa, além de relatos que evidenciam um aumento significativo na motivação dos estudantes após a intervenção.
Kumkapı’daki Göçmen Girişimcilerin Toplumsal Aidiyet Duygularını Anlamaya Yönelik Alan Çalışması
Authors: İlgün Aleyna
Published: December 2024

İlk uygarlıklardan beri göç kavramı çok yaygın olmakla birlikte günümüze kadar etkisi devam etmektedir. Sebepleri değişiklik gösteren göç kavramının günümüzdeki yaygın karşılığı zorunlu göçlerle yer değiştirme hareketidir. Son yıllarda dünyada yaşanan göç olayları son yıllarda en fazla Türkiye’yi etkilemiştir. Bunun sonucu olarak İstanbul’un ucuz yaşam yeri diye nitelendirilen Kumkapı’ya çok fazla göç hareketi gerçekleşmiştir. Bu göç hareketinin başlıca sebebi girişim faaliyetleri olmuştur. Belirli bir ekonomik sermayeye sahip göçmenler Kumkapı’yı kendilerine yaşam ve iş bölgesi seçerek faaliyetlerini sürdürmeye başlamışlardır.

Bu araştırmada göç öncesi, süreci ve sonrasında bölgeye ve halka karşı olan toplumsal aidiyet duygularının nasıl kazanıldığı anlaşılmak istenmiştir. Bunun adına küçük bir araştırma grubu ile görüşmeler yapılmış ve sonuçlar analiz edilerek göçmen girişimci grubunun aidiyet duygusu çeşitli olay ve durumlarla araştırmaya sunulmuştur.
OPTİMAL VERGİLEME (Optimal Vergileme Teorisinin Doğuşu, Gelişimi ve Geleceği: Literatüre Eleştirel Bir Bakış)
Authors: Aktan Coşkun Can
Published: December 2024

Bu makale optimal vergilemeye ilişkin literatüre giriş niteliğinde bir çalışmadır. Doğru ve anlamlı sorulara (örneğin, gelir ve servet vergilerine mi yoksa tüketim vergilerine mi ağırlık verilmeli? Tüketim vergileri içerisinde, vergi oranları mallar arasında nasıl düzenlenmeli? Vergi oranları artan oranlı mı yoksa düz oranlı mı olmalı vb.) cevap aramasına rağmen optimal vergileme literatürü oldukça karmaşıktır; matematiksel formüllerin ve geometrik açıklamaların aşırı kullanımı nedeniyle anlaşılması kolay değildir. Çalışmamızda optimal vergilemenin teorik temelleri ortaya konulduktan sonra sözkonusu yaklaşımın gerçek dünyadaki vergi sorunlarına ne derece katkı sunduğuna dair eleştirilerin bir özetini sunulmaktadır.
Anahtar Kelimeler: Optimal Vergileme, Refah İktisadı, Ramsey Optimum Vergi Kuralı, Ters Esneklik Kuralı

A identidade ciborgue: conflitos do pós- humanismo no filme Transcendence – A Revolução (2014)
Authors: Almeida Gustavo Santos , D' Antony Jean Paul
Published: December 2024

Este artigo, resultado de pesquisa do PIBIC, visa problematizar questões relacionadas ao pós-humanismo a partir do filme Transcendence (2014). O exame de tal questão apresenta uma realidade em que o ciborgue e a sua construção enquanto ser social estão presentes em nosso cotidiano. A abordagem para a realização do presente estudo se edifica no diálogo entre a teoria pós-humana e o cinema, através do método dialético. Buscando reflexões e tendo embasamento em teóricos(as) como Maia (2017), Haraway (2009), Zaboli (2016), Nietzsche (2008), entre outros. Nesse sentido, nosso trabalho também busca entender o processo de hibridização em curso ao longo dos anos, o qual, na medida em que potencializa melhorias no corpo humano, proporciona efeitos transumanos.
