Synchronous Oscillation Suppression in Grid-Forming Converters Using Ultra-Local Model Predictive Control

Grid-forming (GFM) converters play a vital role in future power systems due to their ability to independently establish voltage and frequency. However, their interaction with AC circuits may give rise to synchronous oscillations, which pose a threat to system stability and dynamic performance. This paper investigates the issue of synchronous oscillations and proposes an ultra-local model predictive control strategy for their suppression. First, a small-signal power dynamic model is developed to analyze the mechanism behind these oscillations. It is revealed that this problem is related to the electromagnetic dynamics of power transfer and is strongly influenced by the line impedance characteristics. Then, a predictive control framework is formulated, which incorporates oscillation suppression into the control objective and enables the real-time optimization of the active power reference. To avoid reliance on detailed system models, an ultra-local modeling approach is introduced. In this framework, a fixed-time sliding mode observer is employed to estimate the system power dynamics in real time, enabling the prediction of future states without requiring grid-side parameters and facilitating the design of a model-free controller. Simulation results verify that the proposed method effectively mitigates synchronous oscillations while significantly enhancing system stability and robustness.

Power and marginalization in discourse on AI in education (AIEd): social actors’ representation in China Daily (2018–2023)

Artificial Intelligence in Education (AIEd) has the potential to transform educational practice, and its media representation both reflects and reshapes public perceptions of this new technology. While interest in AIEd is growing worldwide, not all social actors are represented equally. Moreover, limited media coverage contributes to a scarcity of studies on AIEd media representations. This study examines how social actors are represented in AIEd discourses in China Daily (2018–2023), using 100 news articles selected through stratified proportional sampling in Nexis Uni to ensure balanced coverage across all years. Employing intertextuality analysis and social actor theory, the results show that government and corporate voices dominate, while public perspectives are marginalized. Discursive strategies, including objectivation, functionalization, and activation, construct a hierarchical collaboration, where government actors are activated to emphasize leadership, and corporate actors are functionalized as enabler to state-defined goals. Intertextuality analysis highlights co-occurrence between corporate and parental discourses, which risks prioritizing commercial interests over educational equity. This alignment weakened after 2021, reflecting a shift in government efforts to regulate educational commercialization. These findings show a hierarchical power dynamic in AIEd discourses, where government actors dominate and corporate actors subordinate, while public voices are marginalized. This framing prioritizes the institutional corporate and state interests, and limits inclusivity and diversity. This study advances the understanding of AIEd media discourses in a context distinct from Western-centric perspectives. By unpacking the imbalanced representations of social actors, this study uncovers the underlying power dynamics and ideologies in AIEd discourse. It encourages policymakers, educators, and media professionals to address equity and inclusion in media representations.

Powerful Women, Men in Power: An Analysis of Kösem Sultan and Lady Macbeth

There has been an intricate relationship and interconnectedness between gender and power/authority throughout human culture and history. From the male rulers of kingdoms to the male leaders of nations, the power dynamic has been structured around male participation, with various forms of power in the hands of men. Two powerful fictional female characters created in Turkish and English literature, A. Turan Oflazoğlu’s Kösem Sultan and William Shakespeare’s Lady Macbeth, will be analysed in this study to reflect the distribution of power by gender. These two strong female characters at the centre of this study, are remarkable for their intelligence, ambition and lust for power. Since the qualities associated with incompletion and fragility are ascribed to women, they have only indirectly come to power because they are not men. By considering the practices that are effective in social and political life such as the sultanate system and the great chain of being in the fictional periods in which the plays are set, the link between the concept of power and gender will be revealed. The relationship between power and gender will also be evaluated in the context of Simone de Beauvoir's ideas on male domination and Michel Foucault's ideas on power, as they have a significant impact on the perception of power and gender in today’s societies. Therefore, this study will highlight the relationship of power dynamics with gender issues through the analysis of the plays Kösem Sultan and Macbeth by referring to the ideas of Foucault and Beauvoir.

Shifting Tides: Analyzing the Evolving Power Dynamics in the Asia-Pacific Region

Geopolitics across the Asia-Pacific region is being powerfully reshaped by shifting power dynamics, strengthening strategic competition and growing economic interdependence. The way in which the power dynamic in this region is evolving is analyzed in this study through three core dimensions, namely, major power and alliance, economic interdependence, and security architecture, in three tentative regions that have been previously defined. The study uses data from popular sources like World Bank, SIPRI and IMF to conduct descriptive statistics, correlation analysis, and comparative analysis to establish trends, relationships, as well as variations in the region’s geopolitical landscape. The most important finding is that the US-China rivalry broadly remains the central axis of regional geopolitics, with the US symbolically dominating in military expenditure (800 billion) and alliances networks, however, Chinese rapid economic and military rise (challenges (800 billion) and alliances networks, however, Chinese rapid economic and military rise (challenges the status on 250 billion in military spending) the status quo. However, ASEAN’s centrality in responding to Chinese influence is being undermined, while middle powers play an increasingly significant role in balancing China in an effort to do so: Japan and India are two important cases in point. Economic interdependence fosters both cooperation and competition, with countries like Japan and South Korea heavily reliant on trade with China (22% and 25% of total trade, respectively) but cautious about over-dependence. Trade dependence on China appears to have a negative correlation with military expenditure, although trade dependence appears to have few, if any, restraints on defense spending as it is evident from India that provides exception to this rule. Using the study’s quantitative method enables a powerful and data driven method of understanding the region’s power dynamics, through the use of tools such as bar charts, line graphs, and correlation tables. Limitations of the cross-sectional data do not allow for concluding about causality and thus require further qualitative research to reveal mechanisms underlying the relationships observed. The lessons are important for policymakers and stakeholders to note as the regional governance moves towards inclusive and multi-lateral ways in an age of geopolitical uncertainty. This study adds to the broader literature on international relations by n effect of these factors that combine statistical rigor with practical relevance and offers a basis for future research on the Asia-Pacific region.

Power Dynamics in Sport Governance and the Potential of Scientific/Intellectual Movements (SIMs) for Maintaining the Balance of Power: Literature Review and Future Agenda

Problem. The modern sport governance is characterised by an unbalanced power dynamic, which often leads to controversy in decision making and distribution of resource. This imbalance not only influences the honesty of sport competitions, but also impedes sustainable development of sport organisation and its positive impact on society. Our approach constitutes an analysis of the impact of Scientific/Intellectual Movements (SIMs) on power structures in sport governance. Using a qualitative approach of analysing case studies and of examining the theoretical framework, we research into the ways in which actors in sport industry create the dynamic of power. The aim of this study is to reveal the mechanisms that enable using and contesting power in sport governance and to research the potential of SIMs for facilitating more honest power relations. Study results. Power in sport governance is concentrated among a few main actors, who have a disproportionately large impact. However, the present study examined the ways in which SIMs can facilitate the balance of power relations, encouraging transparent, accountable, honest and inclusive governance. Conclusions. To avoid imbalance in sport governance, it is necessary to embrace conscious and deliberate governance structures and ethical principles of governance. The study highlighted the decisive role of SIMs in contesting the existing power hierarchies and facilitating a more democratic and just paradigm of sport governance.

"One Day It Will Happen For Us": The Power of Academia in Community-University Service-Learning Partnerships

This qualitative research explores the community-university partnership experience from the perspective of community organizations engaged in a service-learning (SL) relationship with a private university in a developing country with a collectivist culture. The research explores the relational exchange among partners and foregrounds the issues of power and power redistribution in SL partnerships. The conceptual framework used is informed by conceptions from Dewey (1986), Freire (1996), values of democratic engagement (Saltmarsh et al., 2009), and the critical SL framework (Mitchell, 2008). Findings indicated that faculty were engaged in a traditional SL model in which the focus was not on the process of engagement but on the outcome of the SL experience. The definition of a partnership from community partners was linked to gains and to current or future access to resources. The perception and definition of power impacted community respondents’ reactions to the power dynamic in the ongoing interactions. Being situated in a collectivist culture seemed to impact the community members’ acceptance of unequal relationships. Findings suggested that in a collectivist context, partnerships cannot be examined without considering the context and culture in which the relationship takes place, as both will impact how a community partner defines an authentic relationship and, accordingly, what they expect from the partnership. The power of academia can be intimidating to community partners, so faculty must proactively map out power differentials and initiate reflections and discussions on power dynamics as part of the partnership building process.

Opportunity to Export Fish Directly From the Outermost Islands of Indonesia: Exploring Value Chain and Power Dynamics in Fisheries

The fishers in the outermost islands of Indonesia have an abundant fish catch but local markets have limited capacity to absorb large quantities of fish which limits the potential economic returns to the fishers. This research examines the current fishing value chain in the Sangihe and Talaud islands, which are considered the outermost locations in Indonesia. The study also investigates the roles and influence of each participant within the value chain and the potential for direct export of fishery goods from these islands, bypassing transit points. The contemporary fishing value chain, power dynamic, and fishery direct export issue were investigated through a series of interviews with relevant actors, field observations, and focus group discussions. The results show that the fishing value chain experiences congestion due to the absence of alternative channels for fishers to directly sell their catch, hence relying solely on intermediaries. It also found that fishers have a heightened vulnerability as they lack the capacity to negotiate seafood pricing. Sangihe and Talaud islands are favourable locations for the direct export of fishery goods to General Santos in the Philippines, which provides a potential viable solution for the expansion of the fisheries markets. Currently, the Sangihe local administration is taking steps to implement the direct export of fishing products. The General Santos Fish Port Complex authority and other fishing firms in General Santos have responded favourably to this initiative. These initiates suggest that the outermost regions of Indonesia should be capable of influencing its geographical proximity to export destination countries for fostering economic development within the region.

Negotiating censorial power and its legitimacy: a case study of the second face of state censorship

ABSTRACT This article proposes the ‘second face of censorship’, emphasizing how states use censorial institutions to reinforce their value system and moral authority. It argues that censorship involves an interactive power dynamic between state censors and society, posing the question of legitimacy in censorial power dynamics, which is crucial for authoritarian resilience. To investigate this interactive process and the possibility of legitimacy, this article conducted a case study of public reactions to the takedown of a drama series in China. It examines how public sentiment and state responses intertwined in censorial practice, revealing the construction of descriptive legitimacy through negotiation.

Power Dynamics, Oppression and Resistance (2019)

This research investigates the postcolonial issues in Uzma Aslam Khan's "The Miraculous True History of Nomi Ali," (2019) by using the theoretical framework developed by Walter Mignolo. The research begins by discussing the intricate interplay between the power dynamic, oppression and resistance in the novel which sets the stage for an investigation of the postcolonial theme. The main research question will examine the way in which Khan's story confronts the lasting consequences of colonialism. it is the aim of understanding how marginalized voices are represented as well as their resistance forms. By utilizing Mignolo's theories of colonialism and power, as well as notions of border, this study seeks to discover the contribution of the novel to the debate of postcolonial identity as well as resisting decoloniality. this study highlights the power of Mignolo's theory-based approach to studying Khan's work and reveals how the novel doesn't just criticize remnants of the colonial power structure, but also highlights the resilience and power of the marginalized against ongoing discrimination and oppression.

Embracing complexity: rethinking education inspection in England

ABSTRACT This theoretical paper provides valuable insights into the ongoing debates on OfSTED’s fitness for purpose and effectiveness. It critically examines the current education inspection system in England through the lens of complexity theory. The paper begins with a review of significant changes in the system from 2019 to the present, explaining that education inspection, as a complex system, is characterised by path-dependence, self-organisation, co-evolution, emergence, interdependence and adaptability. This is followed by a comprehensive discussion concerning the underlying power dynamics contributing to the gradual lock-in of the inspection system over the past three decades. Furthermore, it evaluates whether the system has reached a tipping point, potentially transitioning towards a new era. The complexity theory equips change agents, policymakers, policy implementers and school practitioners with a useful theoretical framework to navigate the landscape of educational inspection and facilitate meaningful changes. For change agents to embrace complexity thinking when envisioning a new inspection system, this paper presents several recommendations: surveying the evolving landscape and collecting new evidence, benchmarking against other inspection systems, balancing the power dynamic between OfSTED and schools and paying switching costs while incentivising change adopters.

Paradise Lost of Language Decoding Li Guo-Hua's Linguistic Manipulation in Fang Si-Chis First Love Paradise with the Foucauldian Discourse

This study investigates the power dynamics in Fang Si-Chi's First Love Paradise, a work by the late Taiwanese author Lin Yi-Han, using the Foucauldian Discourse Analysis method. Specifically, it focuses on the linguistic interactions between the main characters to uncover the power structures at play. The analysis reveals that Li Guo-Hua's manipulation of language, within the context of classic Chinese literature, plays a pivotal role in establishing and perpetuating his power. Throughout the narrative, Li Guo-Hua subjects Fang Si-Chi to prolonged sexual and psychological abuse, thereby creating a power dynamic characteristic of Foucauldian discourse. He positions himself as her teacher, exerting control through the distortion of truthful knowledge, linguistic manipulation, and the denial of Fang's agency. This research sheds light on how power can be intricately woven into language and discourse, enabling the exploitation of individuals within intimate relationships. The findings underscore the importance of critically examining linguistic power dynamics in literary works, as they reflect broader societal constructs and behaviors.

Examining Foreign Development Assistance in Africa through Emerging Power Dynamics: A Focus on Turkey’s Engagement in the Horn of Africa

In the last two and a half decades of the 21st century, a modern-day “scramble” for Africa, led by traditional Western powers, has taken shape. This coincides with Africa’s expanding external relations, notably with non-traditional powers like Brazil, Russia, India, China, and South Africa (BRICS). The emerging powers share an objective of advancing their interests in Africa, particularly through exploiting its strategic resources. Turkey has also joined this narrative, yet existing scholarly literature focuses disproportionately on the BRICS, sidelining other players like Turkey. This article addresses this gap by comprehensively investigating Turkey’s distinctive role and its ramifications in Africa. It specifically probes Turkey’s contributions to development in the Horn of Africa, encompassing diverse forms of aid and investments. Turkey strategically wields soft power tools, including humanitarian aid, loans, grants, and technical expertise, to bolster its political and economic sway, thus fostering trade and investment prospects across the Horn of Africa. This engagement has been warmly received, particularly in nations like Somalia and Ethiopia, which have long sought constructive developmental partnerships. This development assistance, however needs to be taken with caution and accompanied by a clear strategy on the mode of response by the Horn of Africa countries in regards to self-guarding themselves from being sucked into a deeper dependence relationship where power is heavily weighted in favor of global powers. This necessitates a clear roadmap to prevent unwarranted dependency on external forces and to preserve a balanced power dynamic. In essence, this study underscores the importance of equitable engagement for sustainable growth and self-determination in the continent.

Supervisee perspectives on improving cultural responsivity in clinical supervision

Culturally responsive supervision has been shown to improve the supervisory relationship and supervision outcomes. This article considers the perspectives of 131 supervisees (trainee/qualified Clinical Psychologists, Counselling Psychologists and CBT Therapists) to better understand what may be required to improve culturally responsive supervisory practices. Supervisees completed an online survey and opted into responding to five free text questions. A qualitative approach was used to further explore their answers using thematic analysis. Five major themes were found from the data: integrating race/ethnicity into the profession, attending to the supervisory relationship, increasing cultural competence, addressing the power dynamic, and promoting cultural humility. It was proposed that the supervisor needs to initiate and lead cultural conversations safely and sensitively, particularly as supervisees may be at varying stages of their own cultural development. Supervisees also felt that supervisors should take responsibility to develop their personal and professional cultural identity due to the existing power dynamics inherent within the supervisory relationship. The responsibility of training programmes and professional bodies was also highlighted in integrating cultural responsivity into clinical training on a wider level.

Implementing Personal Construct Theory to explore divergent approaches to substantive knowledge in RE

AbstractDivergence is not a new phenomenon in RE in England and Wales. A diverse range of aims and approaches have been promoted since RE provision became compulsory in 1944. Approaches include the phenomenological, interpretative, and dialogic with current debates centring around the benefits and challenges of a ‘worldviews approach’. There have been a range of responses to this approach, and implementation has been diverse. It may appear that at the heart of this divergence is confusion over the definition of the term 'worldview' and what this entails for teachers: adding content knowledge and diverse sources. However, this paper argues that the divergence is much more significantly rooted in the nature of ‘substantive knowledge’ and the power dynamics associated with who defines, selects and assesses the validity of substantive knowledge. In current research, I am testing the hypothesis that teachers’ personal worldviews influence their choice of substantive knowledge in RE. Through 142 questionnaires and 21 interviews, this power dynamic is being investigated. Employing Kelly’s (Kelly, Personal construct psychology, Norton, 1955) Personal Construct Theory illuminated teachers’ personal worldviews relating to substantive knowledge in RE. Through the completion and analysis of RepGrids, the teachers revealed they taught the ‘good’ aspects of religions and ignored the ‘bad’. They prized knowledge from lived experience above knowledge provided by religious institutions and some deemed online sources more useful than those from religious institutions. The power to define ‘substantive’ knowledge, once primarily in the hands of religious institutions, has dissipated to embrace definitions from teachers’ personal worldviews. Whilst enabling a diversity of beliefs to be covered, without examination, hegemonic power may risk the validity of the subject. What is needed, in the midst of this divergence, is not a battle for supremacy, and a rejection of one voice over the other, but an acknowledgement of the power dynamics in defining substantive knowledge in RE.

Domestic/Intimate Partner Violence, Abuse, and Trauma During COVID-19 Lockdown: Gaslighting, Non-consensual Condom Removal, Grooming, Coercive Control, Power Dynamic, and Sexual Entitlement in Emotional and Psychological Abuse

The COVID-19 outbreak has amplified psychosocial and emotional stressors for the more vulnerable segments of population. This article explored the drastic increase in emotional/psychological forms of abuse in intimate partner violence during COVID-19 lockdown period. Additionally, predisposing, precipitating, and perpetuating factors of gaslighting abuse, including non-consensual condom removal, grooming, love bombing, coercion, and power dynamics in controlling relationship, are discussed. Published articles on PubMed, Embase, Google Scholar, and Elsevier about psychological aspects of abuse in intimate partner violence during COVID-19 have been considered and reviewed. This article facilitates a solution-focused response for mental healthcare practitioners to support sustainable well-being through collective solidarity, empowerment, and resilience for survivors. This article introduced personal-collective growth process through humanistic-centered approaches for individuals to share their experiences, realign meaningfulness, create hope, and develop coping strategies.

PHOTOESSAY: Refugee migration: Turning the lens on middle Australia.

This non-traditional research paper explores the role of photojournalism and documentary photography in shifting the power dynamic inherent in photographing refugee migrants in Australia—the refugee as an object of photographic scrutiny. It draws on visual politics literature which argues refugees have been subjected to a particular ‘gaze’, where their migration narratives are mediated, mediatised, dissected and weaponised against them in the name of journalistic public accountability in and for the Global North. This photo-documentary praxis project subverts this ‘gaze’ of the Global North and decolonises the power dynamics of the visual politics of refugee migration by turning the lens on middle Australia. Instead of questioning refugees, this project asks what is our moral responsibility to support them? These images are drawn from three years of photographically documenting the Meanjin (Brisbane) community that rallied around and eventually triggered the release of about 120 medevaced refugee men locked up in an urban motel in Brisbane for more than a year in 2020-21. In these images taken outside the detention centre, community members go ‘on the record’ to articulate their motivations for taking a stand—an enduring Fourth Estate record of their social and political stance as active participants within the mediated democratic process of holding power accountable in the refugee migration space. The refugees central to this project have now been released into the community but as they continue to languish in an immigration purgatory, the project is ongoing and continues to manifest through an activist journalism framework, drawing on human rights-based photojournalism practice.

Leadership and power dynamics in crisis management: implication for brain-drain behaviour – Singaporean government experience during Covid-19

PurposeThis study explored how the Singaporean government responded to the Covid-19 pandemic crisis from early January 2020 to the end of May of the same year. It evaluated the capability of Singapore's leadership management in a crisis during the peak and ravaging period of the Covid-19 pandemic.Design/methodology/approachThe study utilised a systematic design analysis approach, analysing Singaporean cases on the Covid-19 crisis using a systematic and narrative approach to underscore the country's response to the pandemic attack from January 2020 to May 2020.FindingsAgainst the backdrop of Singapore's peculiar political system of government dominated by the ruling People's Action Party (PAP) and culture of bureaucracy, the government has increasingly executed several control measures, including strict travel bans, contact tracing, the circuit breaker–lockdown, mask-wearing, social distancing orders as well as financial support to businesses and employees from top to the bottom in the country. However, the treatment and health issues of the migrant workers in the dormitories continue to be the major concern among academics and scholars. At the same time, policy inadequacies truncate the excellent measure of Singapore's response to Covid-19. The case point review concluded that the mortality rate in Singapore remains low compared to other nations of the world. Singapore's case points unveil fundamental learning that an excellent leadership-driven harmonised strategic model is essential for crisis management in any society. The finding of the analysis demonstrated that Singapore adopted a contingency and value-based leadership model to advance good governance and tackle the spread of the deadly coronavirus in its country.Originality/valueThe study has demonstrated a profound analysis that has not been conducted hitherto. Investigation of the Singapore case point is not a popular analysis among Nigerian scholars. Therefore, from Nigeria's perspective, the study has showcased the good and the wrong sides of a coin in Singapore's leadership and power dynamic in crisis management.

&lt;p class="MsoNormal" style="line-height: 115%;"&gt;&lt;strong&gt;EDITORIAL&lt;/strong&gt;&lt;/p&gt;

This first 2023 Journal of Social Intervention presents a peer reviewed article, three book reviews and an interview in our section Innovation in Practice and Education (IWO). In a sense all the authors write about power dynamics.&#x0D; In the peer reviewed research article Perceptions of informal coercion among care users and mental health professionals, Liesel Vandekerkhove, Jürgen Magerman, Wouter Vanderplasschen and Dirk Meesen focus on the power dynamic between client and professional. Results show that informal coercion can be experienced in a supportive way when certain preconditions are met, but that professionals have limited insight into how their actions are received by care users. The article argues that reducing the use of power in psychiatric care asks for systematic reflection in which care users and their network should participate. It also suggests that professional proximity and alignment with the needs of the client are key in using informal coercion in a respectful and reflective manner.
