Introduction: In this study, approaches based on right-tail unit root tests are used to analyze high-frequency time series. Although these approaches successfully capture unusually extreme price movements (bubbles) in financial markets, they can be biased in policymaking and forecasting. Testing the parameter stability enables the detection of both unusual price behavior and possible change points within the framework of the volatility approach. The break dates that cause the parameter change on the return series can be obtained, and the differentiation in the period can be seen.

Purpose: In this study, the analysis of periods that differ from the “changing parameter values” of the volatility process that emerged after November 2018 in the Borsa Istanbul (BIST) is made by using a new econometric approach in terms of change dates, parameter stability, and explosiveness characteristics. In this way, starting from determining periods with stable parameter values, the volatility process is tested to decide whether or not it shows an explosive feature.

Methodology: This study’s mainstay was published in February 2023. The findings reached within the framework of the knowledge provided by the technique in question will be the first in the applied literature. We used a uniform test for a mildly explosive GARCH process with double supreme statistics for BIST.

Findings: BIST is significantly affected by social and political events. This result implies that the “semi-efficient” market hypothesis for BIST needs to be re-examined in this context.

Introduction: Based on the given experiences, many government institutions failed in their strategic management and planning for managing COVID-19. Meanwhile, when a crisis disrupts a system, institutions lose their direction and fail to make necessary responses.

Purpose: The current study highlighted the impact of social justice and modern governance in providing equitable healthcare services and dealing with crises during the COVID-19 pandemic in developing countries.

Methodology: Cross-country analyses were used based on captured secondary data. We evaluated several indices, including, for example, Crisis Index Indicators, Worldometers, and the Global Health Security (GHS) Index 2019.

Findings: According to the GHS (2019) data, public health service delivery equity was ineffective, socially unjust, and unfair treatment was experienced in the context of the conflict-affected countries. Most conflict-affected countries (Iraq, Nigeria, Afghanistan, and Venezuela) did not have guidelines or public reports committing to providing prioritized healthcare services to the public and healthcare workers. The experience of conflict-affected countries has shown that healthcare disparities still exist. While many governments in conflict-affected countries failed to give equitable access to healthcare services during the COVID-19 pandemic to the public.

In today's contemporary landscape, profound shifts are being driven by technological advancements that are propelling innovation to unprecedented heights. As societal needs and demands are undergoing perpetual evolution, organizations find themselves compelled to be continually pursued excellence, thereby redefining technologies to elicit consumer satisfaction and secure a competitive edge. Concurrently, the prevalence of online decision-making processes is being surged, mirroring a consumer base that is increasingly inclined toward digital transactions and technological interfaces. Moreover, the global proliferation of plastic currency underscores the dynamic nature of societal needs and the imperative for innovation, as individuals are readily adapting to the evolving milieu. This study is being endeavored to elucidate the most salient technologies employed to enhance the customer online decision-making process within the Middle East region. Employing a qualitative research approach rooted in descriptive research philosophy, the study is meticulously analyzing the theoretical and practical implications of these technologies. Furthermore, recommendations and strategic insights are being proffered for both future research endeavors and organizational frameworks, with the aim of fostering seamless operational efficacy.

Network configurations have been proposed as an efficient form of organisation and a promising area of research; however, a lack of conceptual clarity can be noted. The purpose of this review is to allow for a broad appreciation of network configurations and provide guidance for future studies of the concept.

A systematic literature review was conducted based on the PRISMA method; Scopus, Web of Science, PubMed and the Cochrane Library were searched for conference proceedings and journal articles describing organisational networks to integrate resources aimed at care delivery. Around 80 articles were included in the final review and analysed thematically and by use of bibliographic coupling.

The last decades have seen an increase in the frequency of articles describing networks for healthcare delivery. The most common contexts are care for multiple and/or long-term conditions. Three clusters of articles were found, corresponding to different conceptualisations of networks in healthcare: efficiency-enhancing cooperation, efficiency-enhancing integration and involvement for cocreation.

To increase conceptual clarity and allow the research on network configurations in healthcare to produce meta-learnings and guidance to practice, scholars are advised to provide ample descriptions of studied networks and relate them to established network classifications.

The current review has only included articles including networks as a key concept, which provides a focused overview of the use of network configurations but limits the insights into similar approaches not described explicitly as networks.

Consumers nowadays are no longer bystanders in the process of production but are proactive collaborators with the power to co-create value with brands. This study aims to explore the impact of social commerce on the co-creation process of brand value in a social commerce setting.

A questionnaire survey was conducted online to gather 300 eligible responses. The data were empirically validated using the partial least squares structural equation modelling (PLS-SEM) method.

The results indicated that brand engagement (BEN) is vital to brand co-creation (BCC) in social commerce, which could be driven by social-hedonic value (SHV) and social information sharing (SIS).

This study stresses the influence of consumer autonomy in the process of BCC by probing the role of SIS. Moreover, by considering the prevailing trend in social media, this study offers a nuanced perspective on the values of social commerce from the viewpoint of SHV.

This study may serve as a useful guide for practitioners to improve their digital outreach strategy on social commerce to forge stronger relationships, encourage further engagements and promote value co-creation within their brand community.

This examines the effect of relationship quality (RQU) and BEN on BCC through a relational viewpoint.

This study aims to develop and apply a process model for prioritizing and selecting basic research projects in developing countries.

Basic research is mainly funded by governments and since, unlike technological research, it does not have clear business goals, its prioritization is one of the complicated issues in formulating science and technology policy. Adopting a design science research methodology, the authors chose a general framework for project portfolio selection as an appropriate artifact for solving this problem. By customizing it for two specific features of this study, i.e. national scale of the problem and the basic nature of research proposals, the authors developed the proposed framework for solving the problem of priority setting.

The process for selecting basic research proposals consists of several steps, which can be categorized into eight steps including strategic decisions, preparation, pre-screening, evaluating individual proposals, screening, portfolio selection and monitoring. This study emphasizes the necessity of defining goals that can be evaluated for the national basic research portfolio, as a key strategic decision. Evaluating individual proposals is a peer-review-based process. In contrast, portfolio selection is done through a zero-one linear programming model. The validity of the proposed framework has been confirmed based on the data obtained from the Iran National Science Foundation.

To the best of the authors’ knowledge, in this research, for the first time, a mathematical model for prioritizing basic research at the national level has been presented, which effectively contributes to policymaking regarding the development of an optimum national research portfolio.

Companies must no longer just report on corporate sustainability (CS) performance but also demonstrate that they are aligning their strategies with sustainability. However, suitable management control systems (MCS) are required to implement a sustainability strategy. Thereby, sustainability reporting (SR) can also be employed for control purposes. On the other hand, existing MCS can be used to develop SR that goes beyond accountability. Accordingly, this paper explores how this interplay can be designed.

For the study, 20 semi-structured interviews were conducted with persons from ATX and DAX companies. Since the interplay should be examined from a holistic control perspective, the authors used the MCS package of Malmi and Brown as an analysis framework.

Nowadays, merely focusing on reporting is too narrow a view. It is therefore not surprising that the investigation was able to reveal various possible linkages between MCS and SR that span the full range of the MCS package of Malmi and Brown.

Future research should also consider non-listed companies to investigate potential differences and take a closer look at the proposed reciprocal nature of the interplay.

The findings expand the knowledge of how companies can use SR for control purposes and how existing MCS can help develop a reporting that goes beyond accountability.

The study contributes by highlighting the potential of SR to control CS performance from a holistic MCS perspective and likewise the impact of existing MCS on reporting. In addition, different theoretical perspectives are used to explain why the interplay can be designed differently in practice.

With the launch of the Feminist International Assistance Policy (FIAP), the Canadian government named solidarity as a shared value and a driving motivation behind the FIAP. This paper explores how development workers understand and apply solidarity to their work, uncovering the opportunities and constraints they face.

In-depth, semi-structured interviews were conducted with 42 development workers from Canada’s federal development agency between 2019 and 2020. Transcribed data were coded by the author to identify how workers made sense of solidarity within the development industry.

The majority of workers were unsure of how to define or operationalize solidarity, demonstrating confusion. Commonality was routinely mentioned as a facet of solidarity, but workers understood this term in diverse ways, with some considering commonality as a precondition that inhibited a sense of solidarity with development partners in the global South due to differences in living conditions. About a quarter identified power and privilege as necessary considerations in the process of building solidarity, showing potential for bonds across the inequalities that define development. About 40% of workers identified the institutional structure of the organization as an obstacle to solidarity.

This paper presents original data from Canadian development workers, providing the first study of their understanding of solidarity as a development ethic. It shows the gaps between rhetoric and practice while recommending ways for development organizations to meaningfully engage with solidarity in their work.

This paper aims to examine how visual elements used in packaging design relate to diasporic consumer identity and influence aesthetic appreciation.

Drawing on social identity theory, research on aesthetic principles and using a mixed methods approach, two studies are conducted. Study 1 involves a qualitative exploration of the nature of diasporic consumer identity and its relation with visual design in packaging. Study 2 involves quantitative testing and calibration of this relationship and its subsequent influence on aesthetic appreciation.

Diasporic consumers from the Middle East appreciate hybrid visual designs and prefer packaging that strikes an optimum balance of visual elements (colour, shapes, patterns) from the heritage aspects of their ancestral homeland and more contemporary aspects from their culture of living. Preference for balance elicits an overall positive diasporic identity feeling that mediates the relationship with aesthetic appreciation of visual design in packaging.

These findings offer new knowledge about the role of visual design in packaging in delivering symbolic value to diasporic consumers, evidencing how diasporic consumers’ dual identities shape aesthetic appreciation and preferences for hybrid visual designs.

Provides marketing practitioners and packaging designers with a concise and contextual directive for creating visual designs that appeal to a growing segment of diasporic consumers.

This research draws on social identity theory to uncover an aesthetic cultural precept – heritage, yet contemporary – that can inform the development of packaging designs targeting diasporic consumers.
