To encourage more just open educational practices, the purpose of this paper is to describe Jose Medina’s theory of epistemic justice and develop a framework applying this conception of epistemic justice to OEP through learning design. The authors hope this framework will help researchers and practitioners develop more equitable learning experiences in open educational contexts.

This paper is conceptual and design-oriented. This paper seeks to draw relationships between José Medina’s work in The Epistemology of Resistance, recent empirical studies in learning design and OEP. By analyzing relationships between these works, this paper lays out design principles that can empower educators seeking to create equitable open learning experiences.

This paper finds several generative intersections between the social justice centered epistemology presented by Medina, empirical learning design studies and OEP. This study finds that structured learning designs which integrate well-researched principles may provide guidance for further practice and research in ways not generally discussed in open education literature. This paper builds on these findings by describing practical ways these intersections can be implemented in OEP.

To the best of the authors’ knowledge, this is the first theoretical analysis of the relationship between epistemic justice and OEP.

La presente investigación examina la existencia de memoria de largo plazo por medio del cálculo del coeficiente de Hurst y Hurst ajustado, y del análisis de características de estructuras caóticas en la serie del mercado bursátil de Chile, específicamente a través del Índice de Precios Selectivo de Acciones.

Se desarrolló un breve análisis del mercado, según la metodología de Box y Jenkings. La validez de los resultados se realizó por medio de la prueba propuesta por Brock, Dechert y Scheinkman. En segundo lugar, se procedió a analizar la dinámica y patrones del índice y de su rendimiento, para observar si existía evidencia de memoria de largo plazo.

Los resultados demuestran la presencia de esta memoria en el mercado bursátil chileno, determinado a través del índice accionario en dos escalas, diaria y trimestral, lo que además corrobora resultados obtenidos por otros autores, confirmando el uso de la metodología de Rango Re-escaldo para la identificación y determinación de memoria de largo plazo en una serie temporal.

Este estudio permitirá a futuros investigadores realizar análisis similares en otros mercados, aportando un nuevo enfoque al analizar la memoria de la largo plazo y los factores que inciden en ella.

This research examined the existence of long-term memory by calculating the coefficient of Hurst and Hurst set, and the analysis of characteristics of chaotic structures in the series of stock market of Chile, specifically through the Selective Price Index Shares.

A brief analysis of the market was developed, according to Box and Jenkins methodology. The validity of the results was performed by means of the test proposed by Brock, Dechert and Scheinkman. Secondly, we proceeded to analyze the dynamics and patterns of the index and its performance, to see if there was evidence of long-term memory.

The results demonstrate the presence of long-term memory in the Chilean stock market, determined by stock index in two scales, daily and quarterly, which also corroborates results obtained by other authors, confirming the use of the methodology Range Re-scalded for the identification and determination of long-term memory in a time series.

This study will allow future researchers to perform similar analyzes in other markets, providing a new approach when analyzing the long-term memory and the factors that affect it.

Big Data introduces high amounts and new forms of structured, unstructured and semi-structured data into the field of accounting and this requires alternative data management and reporting methods. Generating insights from these new data sources highlight the need for different and interactive forms of visualization in the field of visual analytics. Nonetheless, a considerable gap between the recommendations in research and the current usage in practice is evident. In order to understand and overcome this gap, a detailed analysis of the status quo as well as the identification of potential barriers for adoption is vital. The paper aims to discuss this issue.

A survey with 145 business accountants from Austrian companies from a wide array of business sectors and all hierarchy levels has been conducted. The survey is targeted toward the purpose of this study: identifying barriers, clustered as human-related and technological-related, as well as investigating current practice with respect to interactive visualization use for Big Data.

The lack of knowledge and experience regarding new visualization types and interaction techniques and the sole focus on Microsoft Excel as a visualization tool can be identified as the main barriers, while the use of multiple data sources and the gradual implementation of further software tools determine the first drivers of adoption.

Due to the data collection with a standardized survey, there was no possibility of dealing with participants individually, which could lead to a misinterpretation of the given answers. Further, the sample population is Austrian, which might cause issues in terms of generalizing results to other geographical or cultural heritages.

The study shows that those knowledgeable and familiar with interactive Big Data visualizations indicate high perceived ease of use. It is, therefore, necessary to offer sufficient training as well as user-centered visualizations and technological support to further increase usage within the accounting profession.

A lot of research has been dedicated to the introduction of novel forms of interactive visualizations. However, little focus has been laid on the impact of these new tools for Big Data from a practitioner’s perspective and their needs.

The purpose of this paper is to explore the challenges that are experienced by staff responsible for commissioning liaison psychiatry services and to establish if these are shared by other health professionals.

Using a mixed-methods design, the findings from a mental health commissioner workshop (n = 12) were used to construct a survey that was distributed to health care professionals using an opportunistic framework (n = 98).

Four key themes emerged from the workshop, which was tested using the survey. The importance of secure funding; a better understanding of health care systems and pathways; partnership working and co-production and; access to mental health clinical information in general hospitals. There was broad convergence between commissioners, mental health clinicians and managers, except in relation to gathering and sharing of data. This suggests that poor communication between professionals is of concern.

There were a small number of survey respondents (n = 98). The sampling used an opportunistic framework that targeted commissioner and clinician forums. Using an opportunistic framework, the sample may not be representative. Additionally, multiple pairwise comparisons were conducted during the analysis of the survey responses, increasing the risk that significant results were found by chance.

A number of steps were identified that could be applied in practice. These mainly related to the importance of collecting and communicating data and co-production with commissioners in the design, development and monitoring of liaison psychiatry services.

This is the first study that has specifically considered the challenges associated with the commissioning of liaison psychiatry services.

The article aims to determine the implementation extent of the regulations around appointment and characteristics of audit committees and regulations concerning disclosure of information about the audit committee in Polish practice.

The author analyzed the informative content of management reports and corporate governance statements. The survey covered all domestic companies listed on the Warsaw Stock Exchange in the years from 2017 to 2021.

The new guidelines resulting from hard law had a significant impact on the corporate governance on the Polish capital market. According to the research results, over the analyzed years, the share of companies listed on the Warsaw Stock Exchange, which appointed an audit committee within the supervisory board, clearly increased. Moreover, the research found that in the period under study, not all companies fulfilled the obligation to disclose information about the audit committee resulting from hard law. In particular, this applies to disclosures on how the members of the audit committee acquired competencies in the area of accounting.

The article concerns the operation of the audit committee in public companies listed on the Polish capital market. The study can serve as a reference point for further research on corporate governance. The results of the research may be an indication for those who create legal solutions in the area of corporate governance.

This is the first such comprehensive study on the characteristics of the audit committee and disclosures about the audit committee resulting from the introduction of hard law in this area.

This study aims to identify the counterproductive knowledge behavior (CKB) of volunteers in nonprofit organizations and its influencing factors, based on the theories of planned behavior and well-being.

An online survey was used to collect 496 valid responses. A structural equation model was constructed, and the relationships among the constructs were estimated via the maximum likelihood method. To analyze the direct and indirect effects, 2,000 bootstrapping runs were conducted. A Kruskal-Wallis test was also conducted to analyze the relationship between the variables.

A combination of organizational factors and individual attitudes and perceptions can be used to explain CKB. Insecurity about knowledge sharing had the greatest impact on CKB. A competitive organizational norm induced CKB while a knowledge-sharing organizational norm did not have a significant impact. Further, the more self-determined the volunteer activity was, the more the CKB was suppressed. However, well-being did not have a significant direct effect. Volunteers with high levels of well-being and self-determination had significantly lower levels of insecurity about knowledge sharing compared to those who did not.

Well-being arising from volunteering did not directly suppress CKB. To improve organizational efficiency by reducing CKB, nonprofit organization managers should provide intrinsically motivating tasks and interact with the volunteers.

There is a lack of empirical research on CKB in volunteer organizations; therefore, the authors propose a new approach to knowledge management in volunteer activities.

Logistics and supply chain management has been elevated to a strategic level whereby firms can simultaneously achieve differentiation and low cost for sustained competitive advantage. Empirical studies have often concentrated on logistics management in developed Western countries, displaying a bias towards the USA. This study applies the competency approach to explore logistics in Taiwan. A survey of 1,200 manufacturing firms was undertaken in order to examine the relationships between logistics competency, logistics performance, and financial performance, using exploratory factor analysis and the structural equation modelling technique. Four logistics competencies, namely, integration and knowledge competency, customer focused logistics competency, measurement competency, and agility competency were identified. The research findings revealed that (1) logistics competency was significantly related to logistics performance but not significantly associated with financial performance, and (2) logistics performance was positively associated with financial performance. These findings also implied that logistics competency has an indirect effect on financial performance through logistics performance. This finding confirmed the “world-class” logistics competencies (i.e. positioning, integration, agility, and measurement) as identified by MSUGLRT (1995). In addition, it suggests that logistics competency in a huge geographic area such as America can have the same effect in a smaller geographic area such as Taiwan.

The purpose of this research is to contribute to knowledge-building on microenterprises in emerging economies, by assessing the determinants that drive their use of accounting systems.

A probabilistic model was developed to determine the likelihood that a micro-firm would adopt an accounting registry system as a function of a series of contingencies and personal characteristics of their owners/managers. Data from the Microentrepreneurship Survey (EME), from the National Institute of Statistics of Chile for 2017 was used.

The findings suggest that access to external funds, the size and the use of technology strongly influence micro-firms' adoption of accounting systems.

Despite the richness and scope of the data, direct measurements of entrepreneurial orientation and environmental uncertainty, both central variables of the contingency theory, were missing. Hence, duly justified proxies were applied. It is also likely that there would be other variables that also influence the probability of using accounting tools.

The study contributes to a better understanding of microenterprises, and the factors that determine the use of accounting systems. The results highlight that public policies aimed at fostering microenterprises should facilitate access to technology and external funds. Consistent with previous studies, the authors’ findings highlight the importance of training owner/managers on issues related to their business.

This paper contributes to theory by arguably being the first study to confirm that contingency theory does explain the adoption of accounting systems in microenterprises in emerging countries.

The purpose of this study is to evaluate the effectiveness of “Connect the circle” systems thinking tools for improving contextualised systems thinking from sustainability perspectives. The guiding question is could “Connect the circle” improve sustainability education?

The effect of the “Connect the circle” tool on the development of learning dimensions, especially improved problem understanding, shared vision and quality of communication in STEM modules, was analysed by qualitative and quantitative methods.

Authors find that “Connect the circle” is an effective tool for thinking skills development. However, scaffolding in education is required to achieve higher-order thinking skills by empowering students to become active agents of change, capable of envisioning and implementing sustainable solutions at multiple levels.

Educators must bridge gaps between systems theory and understanding how systems thinking skills should be developed in sustainability contexts. Insights from this research will support the development of knowledge and skills required for higher education institutions graduates to address complex sustainability issues.

Applying this tool to STEM curricula represents an original way to explain student holistic vision to connect systems theory to the application of systems thinking skills for sustainability change.

The sharing economy (SE) is significantly affecting traditional companies, which have felt a need to adapt their business model. The aim of this study is to identify the different types of adaptation developed by companies within a SE context, and to examine how they relate to their characteristics.

A content analysis involving 149 real-world adaptation cases was carried out, after which a Kruskal–Wallis test and a multiple correspondence analysis were used to explore the relationships between the types of adaptation identified, the business characteristics and the strategic decisions taken for these adaptations.

Through the analyses proposed in the study, the main conclusions suggest that the way companies adapt to SE is related to business characteristics and the strategic decisions taken for these actions, demonstrating throughout the article what types of adaptations are made depending on variables such as sector of activity or business orientation.

This study is the first to examine the variables affecting the decisions among traditional companies in response to the SE. In addition, this work explores the SE from the business point of view, shedding light on the participation in SE by traditional companies.
