Authors: Mohd Aripin Norhana , Nawanir Gusman , Hussain Suhaidah , Mahmud Fatimah , Lee Khai Loon
Published: March 2024

This study aims to investigate the relationship between sustaining factors and lean manufacturing implementation. This survey-based study was a cross-sectional study and the samples were drawn by using cluster sampling procedure from medium and large manufacturing companies based on the Federation of Manufacturers Malaysia (FMM) with the final number of 151 respondents. In total, four hypotheses were developed and tested statically using PLS-SEM through SmartPLS software. The result provided evidence that lean culture, lean leadership, and lean knowledge management have a positive relationship on lean manufacturing implementation. However, lean supplier management does not have a positive relationship on lean manufacturing implementation. The survey was responded by middle and top-level management from the discrete manufacturing industries. Although there is growing interest in empirical shreds of evidence in favor of sustaining lean, this study provides a comprehensive view of sustaining factors for lean manufacturing implementation. Hence, this study contributes to expanding the boundary of the existing literature and contributes to the body of knowledge while providing insights to practitioners in tailoring strategies to sustain lean manufacturing implementation and leverage their performance.

Published: March 2024

Nanolubricants can improve the tribological properties for application in automotive systems. By reducing the friction rate of the internal components with nanolubricants, the service life of a compressor used in automotive air conditioning (AAC) can be extended. The investigation aims to determine the optimal volume concentration of nanolubricants for achieving the highest performance in tribological properties. Al2O3 nanoparticles dispersed in a polyalkylene glycol (PAG ND12) base at volume concentrations of 0.01%, 0.03%, and 0.05% were investigated to improve the lubrication system in the AAC compressor. The stability investigations were carried out by comparing absorbance conditions using a UV-Vis Spectrophotometer at each volume concentration for 210 days. Koehler's four-ball tribometer was used to measure coefficient of friction (COF) and friction torque at a load of 40.0 kg and a speed of 1200 rpm. The stability study of nanolubricant yielded average absorbance values of 0.752, 0.755, and 0.684, respectively. The average COF values of the nanolubricants of 0.01%, 0.03%, and 0.05% were 0.104, 0.078, and 0.117, while the pure lubricant was 0.095. Further investigation on friction torque resulted in a decrease in the pure lubricant of 0.064%, and for nanolubricant Al2O3/PAG ND12, a decrease of 0.087%, 0.057%, and 0.092%, respectively. The results indicated that a concentration of 0.03% produced the greatest reduction in COF and torque, namely 0.0078% and 0.0578%, correspondingly. Therefore, it is recommended to use Al2O3/PAG ND12 nanolubricant at a volume concentration of 0.03% because it is the most optimal in terms of stability and has the highest COF and frictional torque reduction.

Sub-National Authoritarianism after the New Order: Relationship of Political Recruitment and Political Culture with Political Dynasties in Indonesia
Authors: Delsya Kartika , Permana Panji Anugrah
Published: March 2024

The transition of the Indonesian government from a centralized to a decentralized one, marked by the granting of autonomy to the regions to manage their regions, raises political problems. One of the political problems is the emergence of political dynasties at the sub-national level. The emergence of political dynasties in regional elections at the sub-national level in Indonesia has experienced a significant increase. For this reason, this article will research the emergence of political dynasties in regional elections at the sub-national level in Indonesia. The method used in this research is the literature study method. A literature study is related to data collection methods that involve reviewing literature, reading and taking notes, and processing research materials. The results of this study indicate that, apart from weak regulations, another aspect that causes the emergence of political dynasties is the process of political recruitment by political parties that nominate candidates based on the capacity of candidates as regional heads. Nominations for regional heads by political parties are based on the local community's political culture, which wants to maintain the status quo. Political parties carry out unfair political recruitment to nominate candidates for regional heads so that they nominate candidates from political dynasties by using the image of their predecessors, which makes the emergence of political dynasties more and more common in Indonesia, especially at the sub-national level. Therefore, the recruitment of political parties to elect regional head candidates is highly dependent on the political culture of the local community. The link between society's political culture and political recruitment has led to the emergence of political dynasties at the sub-national level in Indonesia.

Non-Wood Pulping
Authors:   Hehner and Cox Ltd, Grant Julius
Published: March 2024

The theme of this paper is a comparison of the role, properties, and technology of fibrous paper-making raw materials other than wood, with those of wood. Aspects considered are the economic role in world pulp supplies, the nature and properties of the fibres, technological problems arising in pulping, the properties and economic status of the resulting pulps, and the present and likely future of fundamental research. To the vast majority of those connected with paper manufacture “cellulose pulp” is instinctively synonymous with wood pulp, especially in North American and Scandinavia. The aim of this paper is to redress this tendency, in particular from the point of view of the title of this Symposium. This is attempted by a comparison from all relevant aspects of the role, properties and technology of fibrous cellulose paper-making raw materials other than wood with those of wood. Thus, non-cellulose fibres (as of asbestos or glass) and modified cellulose fibres (usually derived from wood) are excluded.
Ultrasonic Characteristics of Fibre Suspensions

Published: March 2024

This paper presents the results of an experimental and theoretical investigation into the fundamental mechanisms that govern ultrasonic propagation in fibre slurries. An experimental apparatus which measures the attenuation and velocity of ultrasound in slurries is described. Measurements on wood fibre slurries show, in contrast to previous work, that the effect of the fibre on the velocity of ultrasound is negligible. This observation led to the development of an isolated segment model, which can predict attenuation as a function of fibre properties and ultrasonic frequency. The theory assumes the fibres are isolated, isotropic, infinite cylinders. It accounts for scattering, heat conduction, viscous losses in the fluid, and relaxation processes in the fibre. Experiment and theory are shown to be in good agreement for some synthetic fibre slurries. In the more complicated case of wood fibre suspensions, the theory predicts attenuation to the correct order of magnitude and permits speculation about the effects of fibre properties.

Published: March 2024

The relationship between the torsional and flexural rigidity of single fibres, and the flow resistance of pulp suspensions was investigated from the point of the flocculation process. The torsional and flexural properties of wetted single pulp fibres were measured by the torsional pendulum method and by the bending method respectively, for chemical pulps. A new experimental apparatus to measure the flow resistance of dilute fibre suspensions to rotary motion was developed in our laboratory. A good correlation between torsional rigidity and the flexural property of single pulp fibres was observed, and the flexibility of fibres was found to increase intensely during the early stages of beating. It was found that wall-shear stress, motion decay times, and the shapes of the motion decay curves of fibre suspensions depended on the flexural properties of the fibres, their length, and the concentration and temperature of the suspension.

Published: March 2024

A wave theory describing paper as a three-dimensional homogeneous orthotropic plate is discussed, and the theory compared with experiment. The results indicate that as long as the wavelength is large compared to typical fibre dimensions, paper may be considered to behave as a homogeneous orthotropic plate. This allows determination of all nine orthotropic elastic constants. Measurement of the three Young’s moduli, the in-plane shear modulus, and the in-plane Poisson’s ratios were made as functions of fibre orientation, wet straining, and density. Qualitatively, the results show that a variable producing a change in properties in one direction, alters the properties in the other two directions in a predictable way. The in-plane shear modulus and the Poisson’s ratios, expressed as (vₓᵧvᵧₓ)¹/² were found to be relatively insensitive to fibre orientation and wet straining, except at the highest levels of each.

Published: March 2024

The particular role played by a contract research laboratory such as Battelle will be examined. This role is affected by the different approaches which a contract research laboratory has necessarily to adopt. Specific single-company sponsored research, as opposed to government or multi-company programmes, is seldom fundamental. However, the advantages of using a nonspecialised laboratory to address specialised problems are several, and examples will be given of the results which can be obtained in this context.

Some Key Points to Consider in Conducting Research in the Paper Industry
Authors:   Omni-Continental Ltd ., New Westminster, Canada, Mardon Jasper
Published: March 2024

It is wrong to consider that there is anything unique in the conducting of research (and development) in the paper industry. The only difference between this and other industries, is the management attitude which has resulted in the situation described by Ron Allan in his paper (1). Research demands a combination of the correct organisation, able people, and insight. Insight is a rare characteristic: it is the one that distinguishes “great captains” from mediocre generals. In managing research for productive ends the rules are the same as for any other management task, but the boundary conditions are different.
Fracture Modes of Sheet Materials

Published: March 2024

I would like to draw your attention to the fact that the fibres of which paper is made retain their individuality in the sheet, even in dense papers. In many experiments, conditions are such that the discontinuous structure of paper has little chance to show. This is why the modulus of elasticity, for example, comes out the same whether it is determined by bending, by a sonic method, or by stretching in a tensile tester of standardized inertia. Such experiments assure us that the laws of continuum physics are consistent and that it is still worth reading and studying them.

Published: March 2024

The aim of the present investigation is to find out those variables of the paper-making process that cause variation in the light transmission of paper, independently of basis weight variation. Furthermore, is intended to discover under what conditions and to what accuracy the distribution of areal mass (formation) can be characterised by the areal distribution of light transmittance. The study is carried out by measuring values of beta-ray transmission and light transmission at exactly the same points of paper samples using an aperture of 1 mm diameter and analysing the correlation of the results. At this stage of the study the effects of furnish composition, beating, wet pressing, and calendering on the correlation between mass distribution and distribution of transmittance have been analysed. It can be seen that at least prolonged beating and heavy calendering change the distribution of transmittance in such a way that the optical formation measurement does not give a true picture of the distribution of mass.
Application of Image Analysis to Pulp Fibre Characterisation

Published: March 2024

Experimental and analytical techniques are discussed for the application of image analysis to the measurement of fibre length, width, coarseness, and curl. It is shown that automated and manual procedures agree well and the crossed fibre problem can be reduced to insignificance by appropriate sample preparation procedures and the use of a curl factor as a recognition function for crossings. Image analysis is used to characterise the introduction of curl in kraft pulp fibres by high consistency beating, and the removal of curl in the hot disintegration of refiner mechanical pulp.

Research and Development Activities for the Pulp and Paper Industry in the EEC Countries
Authors:   Institut fur Papierfabrikation, Technical University Darmstadt, Gottsching L.
Published: March 2024

Most EEC countries have institutes concerned with research and development for the pulp and paper industry. These institutes are either independent establishments, such as PIRA in Great Britain or the Centre Technique in France, or they are part of larger institutions, such as the paper department of TNO in Holland or the Institute of Paper Technology of the Technical University of Darmstadt in the Federal Republic of Germany. Budgets and personnel and hence the capacity of the research institutes vary considerably, characterised by a total staff of 12 persons minimum to 185 persons maximum. Accordingly, the budget varies between US$ 0.8 – 7 M per institute. The funding of the EEC research institutes is done in various ways, either by the government, or mixed, in the form of government and industrial contributions. A few years ago the EEC commission in Brussels initiated a new funding incentive for certain projects. Since the various research institutes already existed before the EEC was founded, it is not surprising that research strategies continue to have a strong national bias. The multi national character of research is still under-developed. The reason for this is, among other things, that the paper industries in some EEC countries regard international research with a certain suspicion. In addition, active communication and cooperation in research and development are impeded by the fact that much energy must be expended for raising funds . This is bound to lead to pronounced formalisation and to tactical biases in those bodies which are concerned with research and its contents.

Published: March 2024

The cross-border exchange of goods, services, capital, and knowledge has emerged as a crucial driver of economic prosperity. Consequently, the objective of this work is to provide an overview of research trends in foreign and international trade, identifying thematic gaps and outlining areas for future research. To achieve this, a scientometric analysis and a systematic review of literature on the production of Scopus were carried out in the last five years. The findings revealed significant growth in current production, in which information was predominantly in English. Similarly, policy formulation requires a comprehensive approach, with a balance between free markets and protectionism, and an encouragement of participation in trade agreements and free trade agreements that drive multilateral and bilateral integration. Additionally, investments in infrastructure, logistics, and technological innovation, along with an understanding of socioeconomic, cultural, health, and environmental factors, allow for the improvement of connectivity and efficiency in international trade. Nonetheless, considering the environmental impact of trade, trends that aim to strike a balance between trade and environmental conservation, as well as addressing socioeconomic inequality, have emerged.

Authors: Llave Angulo Irvin Luis
Published: March 2024

Objective: Determine the relationship between the sales level and the asset confiscation penalty for taxpayers in the commerce sector in Peru during the period 2013-2020. Methods: The approach was quantitative, relational, with a non-experimental design, and an applied nature. An investigation was conducted through the documentary analysis of reports obtained from National Superintendency of Customs and Tax Administration. The relationship between the sales level declared by taxpayers and the levels of asset confiscation penalties imposed during the period 2013-2020 was evaluated using the Spearman’s Rho correlation coefficient. Results: There is a significant inverse relationship between the sales levels declared by taxpayers and the asset confiscation penalty for not having payment receipts in the interventions carried out by the Tax Administration. Conclusion: In the short term, lower sales levels are associated with a higher probability of committing the offense of not carrying the payment receipt that supports the ownership and/or possession of the goods transported by the taxpayer. This is explained by a weak tax culture and a lack of awareness of the obligation to contribute to the tax authorities.

Objective: Determine the correlation between the interest rate on consumer loans and the collection of the Value Added Tax in Peru during the period 2011-2022. Methods: The research was descriptive and correlational in nature. To measure the relationship between the variables, the Spearman correlation coefficient was used, which is suitable for data that do not meet the normality conditions. A total of 144 monthly observations were analyzed, obtained from the Superintendence of Banking, Insurance and Pension Fund Administrators and the National Superintendency of Customs and Tax Administration. Results: There is a positive correlation between the interest rate on consumer loans and the collection of the value added tax in the period from January 2011 to December 2022. Conclusion: When the interest rate on consumer loans increases, so does the collection of the Value Added Tax. However, the relationship between these variables is not constant and may be subject to changes at different times.

Nanoparticles of (LaF3)0.75Er0.025Yb0.225 and (LaF3)0.75Er0.015Yb0.235  were synthesized using the chemical coprecipitation method and subjected to thermal treatment of 200 °C, 400 °C and 600 °C respectively for 2 hours. The structure of the samples was analyzed through the X-ray diffraction (XRD) technique and RIETVELD modeling by fundamental parameters using the TOPAS software. The size of the crystallites was found to be at nanometric level (between 119 nm and 140.7 nm) and the increment in size of the crystallites was verified as the temperature of the heat treatment was increased. It was possible to verify the change from hexagonal to rhombohedral structure for the samples subjected to 600 °C and a significant increment in the crystallinity of the samples due to the effect of thermal treatment. The SEM-EDS images show the described effects and provide a way to corroborate the growth of the particles (between 538 nm and 778 nm), as well as to obtain the elemental composition of the samples. Finally, the Raman spectrum show a low phonon energy of the samples (between  and), thus ensuring that the loss of the anti-Stokes emission properties of the excited states of the lanthanide ions in the samples due to the cooling effect is minimal.

The urgency of the research problem is due to the official recognition of a new sport -basketball 3x3 as an Olympic sport and a review of theoretical and methodological approaches to the selection and preparation of basketball players to participate in official competitions in 3x3 format. The first official national level competitions are held for players in the U-15 category. Given the lack of a managed training process in the new sport, there was a need for additional training of players in the sections of classical basketball to participate in competitions 3x3.Purpose: to determine the opinion of basketball players aged 15-16 about basketball in 3x3 format.Methods:theoretical (analysis and generalization of scientific and methodological literature, Internet data on the problem of research), empirical (pedagogical (surveys), sociological (questionnaires)).Results: the results of a survey of coaches and a survey of classic players about basketball in 3x3 format are presented. The opinion of the players about the place of the new species, the importance of purposeful preparation for competitions in the 3x3 format is established. Priorities for the use of technical and tactical interactions during competitions in 3x3 format have been identified. The effectiveness of their use in 3x3 basketball in players of this age is analyzed. Conclusions:аmong the vast majority of athletes aged 15-16, training in the sections of classical basketball under the guidance of a coach, 3x3 basketball is very popular and is perceived as a separate sport (70%). 72% of respondents have experience of performing at official competitions in 3x3 format. 85% have a sufficient level of knowledge of the official rules of the new game. Distinguishing between features of competition formats, 87% of respondents expressed the need to train before 3x3 basketball competitions. The opinion of athletes aged 15-16 about the use of tactical interactions during games in 3x3 format partially differs from modern requirements.

FASCISMOS E SISTEMAS E MOVIMENTOS AUTORITÁRIOS E TOTALITÁRIOS: O CASO PORTUGUÊS
Authors: Reis Torgal Luís
Published: March 2024

As revoluções (e as contrarrevoluções), salvo alguns casos de resultados efémeros (como sucedeu com a Revolução de Setembro de 1836, de orientação vintista1), tiveram, em Portugal, um carácter predominantemente militar. Assim sucedeu com a nossa primeira revolução liberal, que se deu no Porto em 24 de agosto de 1820.
OLIVEIRA SALAZAR E A DITADURA DAS FINANÇAS EM PORTUGAL: DE MINISTRO DAS FINANÇAS A LÍDER DO ESTADO NOVO
Authors: Rafael Amaro Antônio
Published: March 2024

O papel dos indivíduos na mudança da História é uma discussão antiga, nomeadamente entre historiadores e investigadores de outras ciências sociais e humanas. São conhecidos os termos do debate e o caminho que foi preciso percorrer para evitar todos os exageros cometidos sobre o papel atribuído às grandes figuras. A correção dessas limitações não evitou, contudo, que certas correntes historiográficas caíssem no polo oposto, arredando totalmente o papel das individualidades de qualquer explicação histórica. Muito recentemente, o historiador alemão Ian Kershaw (2022), no seu livro Personalidade e poder: construtores e demolidores da Europa Moderna.
“QUE EM NENHUM LAR ESPANHOL FALTE O PÃO NEM O LUME”: HISTORIA, MEMORIA Y PROPAGANDA DE LA FALANGE ESPAÑOLA EN PORTUGAL (1936-1939)
Authors: Pena-Rodríguez Alberto
Published: March 2024

La Guerra Civil Española, entre 1936 y 1939, es un período histórico clave para comprender la evolución de las relaciones políticas entre España y Portugal durante el largo período de los regímenes autoritarios que sustentaron el franquismo y el salazarismo, aliados naturales en la consolidación y legitimación política internacional de ambas dictaduras peninsulares. Salazar tuvo una intervención relevante en el desarrollo de la guerra, sobre todo en el contexto diplomático y propagandístico, con importantes consecuencias políticas, sociales y económicas para Portugal, cuyo gobierno actuó como si la guerra española fuera un asunto interno, alegando que el país estaba amenazado por el llamado perigo vermelho tras la victoria del Frente Popular en febrero de 1936, aunque en realidad el temor de Salazar estaba vinculado a la influencia desestabilizadora de la democracia republicana española sobre su régimen autoritario (Delgado, 1980; Oliveira, 1987; Pena Rodríguez, 2014a).
Na prática a teoria é outra
Authors: Zibordi Marcos Antônio
Published: March 2024

O artigo apresenta resultados parciais de pesquisa sobre a presença, em obras jornalísticas, das quatro características do “novo jornalismo”, definidas por Tom Wolfe (2005). Verificamos empiricamente se existe a presença de atributos que seriam literários em livros-reportagem mais citados por teóricos estadunidenses e, sobretudo, brasileiros. Estamos constatando que a narração não ocorre alternando cenas, os narradores não são personagens, os diálogos são raros e os detalhes significativos, quando existem, dificilmente podem ser qualificados como realistas.
Approximations of Singular Surfaces with Standard Cuspidal Edges
Authors: Saji Kentaro , Yamamoto Yoshiki
Published: March 2024

We consider a function from the Euclidean three space whose zero set is the image of the standard cuspidal edge. The composition of a parametrized singular surface in the three space with this function provides an approximation of the surface by the standard cuspidal edge. Taking a look at singularities of this composition, we study various approximations of singular surfaces like the cross cap, the generalized cuspidal edge and the swallowtail by standard cuspidal edges.
Psychedelic-assisted therapy for people with gambling disorder?
Authors: Romero Pedro , Czakó Andrea , van den Brink Wim , Demetrovics Zsolt
Published: March 2024

Gambling disorder is a severe mental health and behavioural problem with harmful consequences, including financial, relationship and mental health problems. The present paper initiates discussion on the use of psychedelics combined with psychotherapeutic support as a potential treatment option for people living with a gambling disorder. Recent studies have shown promising results using psychedelic-assisted therapy (PAT) to treat anxiety, depression, post-traumatic stress disorder, and various substance use disorders. Considering the similarities in the underlying psychosocial and neurobiological mechanisms of gambling disorder and other addictive disorders, the authors suggest that psychedelic-assisted therapy could be effective in treating gambling disorder. The paper also underscores the need for further research into the viability and effectiveness of psychedelic-assisted therapy for gambling disorder.
First recorded sighting of the Critically Endangered Tricolour Langur, Presbytis chrysomelas cruciger (Thomas, 1892) (Primates, Cercopithecidae), in Jemoreng Protected Forest, Sarawak, Malaysia

Presbytis chrysomelas cruciger (Thomas, 1892) is a Critically Endangered langur subspecies that has rarely been studied due to the difficulty of encountering it in the wild. Previously, this subspecies was sighted in Maludam National Park, Sarawak, Malaysian Borneo. Here, we provide the ﬁrst sighting record of P. c. cruciger in Jemoreng Protected Forest in Sarawak, where a total of eight groups were observed. We urge for further comprehensive studies and immediate conservation action.

Uczestnictwo ludności Polski w kulturze w czasie kryzysu związanego z pandemią COVID-19
Authors: Mazurkiewicz Anna
Published: March 2024

Pandemia COVID-19 wpłynęła na sytuację na całym świecie, doprowadzając do kryzysu w wielu obszarach działalności, w tym w kulturze. Kultura ma pozytywny wpływ na gospodarkę, jest także istotna dla rozwoju osobowości jednostki. Stąd tak ważne jest uczestnictwo w wydarzeniach kulturalnych. Jednak w czasie kryzysu ta możliwość zostaje ograniczona. Celem opracowania jest identyfikacja wpływu ograniczeń związanych z pandemią COVID-19 na uczestnictwo ludności w Polsce w wydarzeniach kulturalnych organizowanych stacjonarnie, z uwzględnieniem poszczególnych form aktywności kulturalnej. Aby zrealizować cel, zastosowano metodę analizy i krytyki piśmiennictwa. Skorzystano z literatury przedmiotu, raportów i opracowań krajowych oraz międzynarodowych instytucji podejmujących problematykę kultury, aktów prawnych. Przeprowadzono okresu 2019–2022. 

Z przeprowadzonych badań wynika, że pandemia spowodowała niespotykany wcześniej kryzys w kulturze w Polsce. Mimo korzystnych zmian w 2022 r. liczba wydarzeń organizowanych przez instytucje kultury była mniejsza niż przed ogłoszeniem pandemii, jednocześnie w wydarzeniach tych uczestniczyło mniej osób. Brak lub ograniczenie uczestnictwa w kulturze osłabia lub doprowadza do zanikania relacji interpersonalnych, ogranicza możliwości oddziaływania na inne jednostki, tym samym podmiotowość.

Dla instytucji kultury pozyskanie odbiorców wymaga wspierania twórczości, kreatywności, otwartości na nowości. Służyć temu może zaproponowanie nowych kanałów kontaktu z odbiorcą, nowych form prezentacji oferty kulturalnej, jednocześnie dotarcie z informacją do osób potencjalnie zainteresowanych, a także rozwój kwalifikacji zatrudnionych osób.
Nierówności odpornościowe państw Unii Europejskiej
Authors: Król Paulina
Published: March 2024

Celem artykułu jest identyfikacja grup państw Unii Europejskiej cechujących się zbliżonym poziomem rezyliencji ekonomicznej w okresie występowania sytuacji kryzysowych oraz zależności pomiędzy poziomem rezyliencji ekonomicznej a poziomem rozwoju gospodarki, ze szczególnym uwzględnieniem Polski. Hipoteza zakłada, że Polska cechuje się słabą odpornością ekonomiczną, a poziom rezyliencji ekonomicznej członków Unii Europejskiej jest skorelowany z poziomem rozwoju gospodarki. Zakres przedmiotowy badania tyczy się poziomu odporności ekonomicznej oraz poziomu rozwoju gospodarki. Zakres podmiotowy badania objął państwa Unii Europejskiej z wyłączeniem Luksemburga i Malty, natomiast czasowy – rok 2021. W artykule zastosowano analizę literatury oraz statystyczną metodę badawczą. Dokonano przeglądu literatury światowej odnoszącej się do sytuacji kryzysowych oraz zagadnienia odporności podmiotów gospodarczych. W empirycznej części artykułu przedstawiono wyniki grupowania krajów Unii Europejskiej ze względu na ich rezyliencję ekonomiczną oraz wyniki analizy współczynnika korelacji pomiędzy odpornością ekonomiczną a poziomem rozwoju gospodarek. Każde państwo Unii Europejskiej cechuje się innym poziomem rezyliencji ekonomicznej. Najwyższy jej poziom cechuje kraje nordyckie i Holandię. Polska, wraz z państwami bałkańskimi, należy do grupy członków UE o najniższym poziomie odporności, jednak dla Polski jest on nieco wyższy w przypadku aspektów związanych z odpornością edukacyjną oraz odpornością finansową. Krajom mniej odpornym, takim jak Polska, może więc być trudniej dostosować się do rezyliencji jako kierunku polityki Komisji Europejskiej. Poziom rozwoju gospodarczego państw jest silnie dodatnio skorelowany z poziomem ich odporności ekonomicznej (po wyłączeniu obserwacji odstającej – Irlandii – współczynnik korelacji Pearsona pomiędzy indeksem odporności ekonomicznej a PKB per capita według PPP za 2021 r. wyniósł 0,883).
