As specific objectives, we intend to: (1) measure the connectivity between the spillovers of returns from the financial and nonfinancial sectors of the Brazilian stock market; (2) estimate the spillovers of individual returns for each sector to identify periods of higher and lower profits over a period of around eight years; (3) investigate the existence of relationships between these repercussions between pairs of sectoral indices, evaluating how much each specific sector transfers to each other and the market as a whole and (4) examine whether the connectivity of the Brazilian stock market itself and future interest rates in the USA and Brazil as well as the risk of the Brazilian economy, were explanatory variables of the dynamics of interdependence in the returns of these indices.

With a daily series of closing prices of sectoral indices from March 3, 2015, until June 21, 2023, we researched eight of the most relevant sectoral indices on the São Paulo Stock Exchange (B3). With this data, we estimate the Diebold–Yilmaz spillover index and frequency decompositions of Barunik–Krehlik.

The conclusions indicate that there is an overall connection of 66% in the financial and nonfinancial sectoral indices, with a peak of 83%. The consumer, energy and public services sectors stand out as significant sources of primary spillovers. When we classified secondary effects into periods, we saw that the shocks dissipated as time passed and the returns of the commodity index remained resilient across all periods.

Our conclusions highlight the influence of three main factors in sectors with a high degree of connectivity: periods of increased uncertainty; negative externalities in post-crisis periods and the impact of financial news on market sentiment. We think this study provides information that can be useful for policymakers, investors, investment portfolio managers, economists (financial, monetary and industrial), investment consultants and researchers who are interested in the complex interconnection among emerging market stock indices.

The records surrounding the assassination of President John F. Kennedy (JFK) have been subject to unique treatment in their management and opening. The John F. Kennedy Assassination Records Collection Act of 1992 (JFK Records Act) mandated that the records would be opened in full by 2017, unless there was intervention from the sitting president. This study aims to examine the extent to which access to the JFK assassination records has been granted. It evaluates how open the archive is, and the consequences of withholding government records. It examines how the continued non-disclosure of this archive has helped to fuel the controversy and conspiracy theories surrounding Kennedy’s death.

This research was approached as traditional historical document analysis, reviewing the JFK assassination records releases from 2017–2018 and the broader landscape of access to information in America. A random sampling of the open and redacted records was used to undertake a statistical analysis on the amount of information that has been withheld. It was supplemented with freedom of information requests intended to reveal further information on the approach taken to redaction. The work was situated within a broader global literature review.

The research identified the limits to access to the JFK assassination records that exist because of the continued postponement and redaction of information by US federal government agencies. It found that the ambiguous language used for exemptions in the US Freedom of Information Act (FOIA) and the JFK Records Act has allowed agencies the freedom to interpret and limit access to information if they desired. Furthermore, agencies have had the power to hold and sanitise their own records. The work identifies how these approaches have caused questions, inconsistences, a lack of transparency and accountability in the US government. The lack of centralised processes and related explanations can be seen to fuel further controversies and conspiracies.

Using a systematic research methodology, this work presents a careful analysis of the varying processes and their implications for understanding of the events that surrounded Kennedy’s assassination. Lessons learnt can be applied to the general management of freedom of information and access to information.

The study will add to the current discourse on the Israel-Hamas conflict by examining the impact of the war on the stock markets of trading partners. Stock market returns inevitably rise as globalization keeps integrating financial markets and economies around the world. Thus, the impact of war is assessed across a range of indicators that are similar in some way, such as geographic location, political climate or economic standing. Thus, the goal of this study is to investigate how the Israel-Hamas war affects trading partner countries' stock performance.

Event study methodology is applied using Morgan Stanley Capital Index (MSCI) as a benchmark index. The influence of the Israel-Hamas war on the world's major stock markets is evaluated using a market model. The study takes into account Israel and its 23 trading partners. To capture the locational asymmetry in the outcome, the countries are further categorized according to their geographic locations. The official declaration of war came on October 7, 2023, a non-trading day. Consequently, October 9, 2023, is designated as the event day in this study. The data was gathered between January 1, 2023, and December 31, 2023, with an estimation period of 140 days taken into account to minimize bias.

Asymmetric response is shown among the nations due to their economic standing, geographic proximity and trading links with Israel. While Austria, Greece, Egypt, Palestine and Israel had the greatest negative effects, Argentina, Japan and Chile saw significant beneficial effects. The remaining nations had little effect. The market quickly adjusted itself, eliminating anomalous returns.

Taking into account the topic's criticality, the current work has certain limits. The study has used the daily data to limit its reach to the stock market exclusively. In the future, academics can combine high-frequency stock market data with data from other macroeconomic variables, such as currency or different commodities markets, to further their research. Furthermore, a cross-national comparison of the impact in terms of direction and intensity regarding developing global groups such as I2U2, LEVANT, BRICS, MIKTA, SCO, NATO, SAARC and OECD can provide a more comprehensive understanding in this context. To gain insight into the durability and adaptation of financial systems over time, longitudinal studies could be conducted to monitor the long-term effects of geopolitical crises on the stock markets of trading partner countries.

By better managing investment portfolios and evaluating potential risks associated with trading partners involved in such conflicts, investors and businesses can lessen the impact of geopolitical tensions on stock market performance. These results contribute to our understanding of how geopolitical conflicts affect stock markets.

This research provides an extensive analysis of the global impact of Israel-Hamas tensions on stock market volatility by taking into account trading partners. This allows for the investigation of how various market structures and economic systems react to geopolitical turmoil. The present study is one of the first attempts to look into how disturbances in one region might affect continents to better understand the dynamics of global trade and economic interdependencies.

The language of participative theatre can be considered immersive in the treatment of its dialectics where participants engage fully with their dichotomies and value systems through physical and psychological exploratory processes as they commit themselves to transformation.

The use of drama as an intervention for challenging recurring mental models of oppressive narratives is used extensively in experiential psychotherapy and as a socio-psychological integrative tool. This experiential methodology allows for an organic development and expression of themes and motifs by encouraging a participant to develop a deeper awareness of how he/she interprets their identity and that of the community in which they function.

This paper aims to review the implications of applying drama-based interventions as positive psychotherapeutic devices to facilitate self-reflection and active-constructive responding in enabling a rendering of positive patterns of thought and purposeful movement towards emotional and physical well-being.

Research on the principles of positive psychology suggests that positive emotions lead to therapeutic change. Nurturing positive emotions which are immanent in spirituality, creativity and optimistic perseverance through autonomy and self-regulation enable individual potential to come to meaningful fruition.

The paper conceptualizes psychodrama as a framing technique in enabling reflexive action in identity transformation and well-being.

In the past decade, against increasing global inequality, higher education has grappled with increased demands for social justice, transformation and decolonisation. While a lot of research in South Africa has focused on the (im)possibilities of fostering racial, gendered, socio-economic and cultural change, the connection of such change to questions of sustainability has been less explored. The purpose of this paper is to specifically explore the agency of academics to foster transformative initiatives for sustainability within the context of institutions historically serving under-represented populations.

Using a qualitative methodology, this paper highlights the importance of considering sustainability in processes of transformation. This paper is specifically interested in how academic faculty and those in assigned leadership positions view their agency in relation to promoting transformation for sustainability at the institutional level. Drawing on data generated from semi-structured interviews with 13 participants at an historically Black university in South Africa, this paper details academics' and leaders’ experiences and perceptions of their agency.

This study reveals the adverse interactional dynamics within higher education institutions, which negatively impact academics’ participation as key agents in change processes. Positional and identity challenges faced reveal the persistence of colonial and apartheid legacies of racism, sexism, Afrophobia and xenophobia – which casts a shadow on possible trajectories of transformation and sustainability. This has serious implications for the common good, given South Africa's regional import for knowledge production and decolonisation within universities; its key role in the African 2063 Agenda; and the wider global Sustainable Development agenda.

This study highlights insufficient engagement with the sustainability of transformation efforts within the context of South Africa. This study also emphasises the relation between transformation imperatives and racial, socio-economic, gender and epistemic justice imperatives of sustainable development.

There is little to no empirical research on the phenomenon of ways in which the racism of whiteness transpires within the faculties and classrooms of US-based ALA-accredited library and information science (LIS) education programs. We do have scholars publishing meaningful work exploring diversity-equity-inclusion topics and initiatives to evolve the LIS discourse on these issues (Honma, 2005; Chancellor, 2019; De LaRosa et al., 2021; Gibson, 2019; Mehra et al., 2023; Colón-Aguirre et al., 2022; Hands, 2022). This research substantiates the conceptual research that exists by empirically exposing the ways in which the racism of whiteness functions at the interpersonal level of work culture in LIS programs (i.e. the academy) in the US.

Adapting Baima and Sude’s (2020) modified Delphi Method, a focus group of 13 BIPOC (Black, Indigenous, and People of Color) library and information science faculty members in the United States were recruited to participate in a one-time 60-min virtual Zoom session. Participants were engaged in three iterative rounds of reflective inquiry to reach a consensus of experience. The study design was embedded with critical race theory-based (CRT) ethnographic methods such as testimony (counterstorytelling), collective affirmation (shared narratives), and silence.

BIPOC LIS faculty (tenure-track and tenured) have similar ideas about whiteness and how it is operationalized as micro- and macro-aggressions in the LIS academic workplace, most significantly inside the classroom. The experience of whiteness was prevalent among all study participants in two areas: workplace meetings with faculty colleagues and classroom sessions (face-to-face and online) with students.

The findings offer empirical evidence to support the prolific conceptual literature in LIS discourse concerning ways in which critical race theory (CRT) interrogates LIS’s socio-professional injustices and inequities (e.g. Gibson et al., 2018; Stauffer, 2020; Leung and Lopez-McKnight, 2021; Jennings and Kinzer, 2022; Snow and Dunbar, 2022). There remains a dearth of empirical research that reports how whiteness is reproduced in the practices, knowledge, and resources that make up the ethos of the LIS faculty meeting and classroom. Documenting the testimonies of BIPOC LIS faculty solidifies the existence of whiteness as a toxic reality in the LIS academy.

Consumers often prefer sustainable goods and services but fail to follow through with purchases that reflect these espoused values. The green intention–outcome gap is studied in many contexts but has yet to inform deathcare decisions. Industry reports suggest that most Americans prefer sustainable deathcare options, yet unsustainable corpse dispositions dominate the market. The purpose of this paper is to understand how history informs this phenonea.

This study looks to the past – using historical narrative analysis of deathcare trends and influential intermediaries – to understand the future of sustainable deathcare and the prospective role that marketers can play in bridging the gap between decedents’ preferences and survivors’ purchase outcomes.

Historical ritualization, medicalization and commercialization have resulted in the monopolization of traditional deathcare services. Mortuary professionals remain unresponsive to consumer preferences for sustainable alternatives.

Socioeconomic shocks can allow humanity to reflect and transition from consumerism to sustainability. COVID-19 has led to greater awareness of self-mortality, and death has become less taboo. The slow market penetration of sustainable deathcare services suggests a lack of communication between a decedent and their survivors. Marketing scholars need to help marketing practitioners bridge the preference-outcome gap.

To the best of the authors’ knowledge, this study is amongst the first to examine how history informs the sustainable action–outcome gap for deathcare preferences in a post-COVID environment and the role that marketers can play in perpetuating change.

Although belief in conspiracy theories has been researched since the 1970s, specific research on conspiratorial thinking in the workplace is scarce. Conspiratorial thinking could be fostered among employees in workplaces because of unequal power relations resulting from the organizational hierarchy. This study examines workplace conspiracy attribution (WCA) as employees’ attribution of problematic events in the workplace as being plotted by powerful actors within their organizations and tests its antecedents and consequences.

A survey dataset collected from employees in South Korea (N = 600) was used. This study tested three variables (i.e. two-way communication, employee–organization relationship quality, and perceived ethical orientation) as antecedent conditions of WCA and two outcome variables (i.e. turnover intention and whistleblowing potential) as consequences.

Perceived ethical orientation mediates the relationship between two-way communication and WCA. WCA was found to be positively associated with turnover intention and whistleblowing potential.

This study adopts a public relations lens to understand the significant roles of WCA in reducing turnover intention and whistleblowing potential. It expands existing knowledge of the significance of power and power disparities in organizations.

This paper aims to consider the role of social media platforms as educational technologies given growing evidence of harms to democracy, society and individuals, particularly through logics of efficiency, racism, misogyny and surveillance inextricably designed into the architectural and algorithmic bones of social media. The paper aims to uncover downsides and drawbacks of for-profit social media, as well as consider the discriminatory design embedded within its blueprints.

The authors used a method of a technological audit, framed through the lenses of technoskepticism and discriminatory design, to consider the unintended downsides and consequences of Twitter and Instagram.

The authors provide evidence from a variety of sources to demonstrate that Instagram and Twitter’s intersection of technological design, systemic oppression, platform capitalism and algorithmic manipulation cause material harm to marginalized people and youth.

The authors contend that it is a conflict of professional ethics to treat social media as an educational technology that should be used by youth in educational settings. Thus, they suggest that future scholarship focus more on addressing methods of teaching about social media rather than teaching with social media.

The paper concludes with recommendations for educators who might work alongside young people to learn about social media while taking informed social actions for more just technological futures.

This paper fulfills an identified need to challenge the direction of the field of social media and education research. It is of use to education scholars, practitioners and policy makers.
