Intersectionality to better understand women's health issues

Intersectionality, a theory for understanding women's health issue. Intersectionality offers the possibility of holistic analyzes to understand and act on women's health issue. It facilitates the exploration of the different dimensions of social inequalities in health, which are both at the level of institutions and of the individual experiences of people who live at the intersection of multiple dimensions of domination and power.

White fragility: An emotion regulation perspective.

To address anti-Black Racism, systemic change across many domains in American life will be necessary. There are many barriers to change, however, and progress requires identifying these barriers and developing tools to overcome them. Given that White individuals disproportionately occupy "gatekeeping" positions of power, one key barrier to systemic change is rooted in White individuals' emotional (and emotion-regulatory) responses when considering their own role in racism (e.g., involvement in racist systems, biased actions). White people often experience such moments as a jeopardy to their valued goals and are consequently highly motivated to reduce the negative emotions that they feel by denying or avoiding the issue-a multifaceted response known as a White fragility response. When White individuals enact a White fragility response, they can further damage the well-being of Black members of their community and weaken their own motivation for systemic change. Given its stark costs, it is critical to understand White fragility responses. In this article, we argue that White fragility can be usefully viewed through the lens of emotion and emotion regulation theory. In particular, we describe the emotion and emotion regulation responses that characterize White fragility, summarize the wide-ranging consequences of White fragility responses, highlight more sustainable ways forward, and end by considering a broader fragility framework that acknowledges multiple dimensions of power. Although emotion regulation lies at the heart of White fragility, emotion regulation is also a tool that can be leveraged for greater justice.

Power and empowerment in transdisciplinary research: a negotiated approach for peri-urban groundwater problems in the Ganges Delta

Abstract. The co-creation of knowledge through a process of mutual learning between scientists and societal actors is an important avenue to advance science and resolve complex problems in society. While the value and principles for such transdisciplinary water research have been well established, the power and empowerment dimensions continue to pose a challenge, even more so in international processes that bring together participants from the Global North and Global South. We build on earlier research to combine known phases, activities, and principles for transdisciplinary water research with a negotiated approach to stakeholder empowerment. Combining these elements, we unpack the power and empowerment dimension in transdisciplinary research for peri-urban groundwater management in the Ganges Delta. Our case experiences show that a negotiated approach offers a useful and needed complement to existing transdisciplinary guidelines. Based on the results, we identify responses to the power and empowerment challenges, which add to existing strategies for transdisciplinary research. A resulting overarching recommendation is to engage with power and politics more explicitly and to do so already from the inception of transdisciplinary activities as a key input for problem framing and research agenda setting.

Navigational Computations of Social Interactions

Humans ability to navigate social situations is akin to physical navigation. This capacity may depend upon social mapping: the hippocampus organizing information about social relationships into a multidimensional map, like that of physical space. In this framework, other people occupy social places based on their locations along abstract social dimensions of power and affiliation.

The Journalism in Climate Change Websites: Their Distinct Forms of Specialism, Content, and Role Perceptions

ABSTRACT Survey results from news consumers around the world suggest that specialist or niche websites covering climate change are now one of the most important sources of climate information. However, there is very little detailed scholarship about these sites. We carried out semi-structured interviews with senior representatives of 14 online information sites, based in the United States, United Kingdom and other countries, which prioritize the provision of climate information following journalistic values. Through qualitative analysis of the interviews, we show how the sites carve out their niche authority and distinctive nature by emphasizing (to different degrees) their scientific expertise, relevance for policy communication, and their complementary contribution to the work of mainstream journalism. They offer a multiplicity of specialized content, broadly divided into certain, often discrete, aspects of climate change. The self-declared role perceptions of the interviewees suggest that traditional, professional journalistic values eschewing overt advocacy still predominate, although some of the practices, norms and priorities associated with these values have shifted, particularly in their roles as effective and authoritative mediators of climate science. At the theoretical level, the findings highlight the need to study “the niche” at the intersection of broader dimensions of authority, power and knowledge in changing media ecologies.

Consumer power: scale development and validation in consumer–firm relationship

PurposeThe purpose of this paper is to report on the development and validation of a consumer power scale comprising a personal and a social power dimension. Personal power refers to consumers’ perceived ability to resist and ignore a firm’s marketing efforts. Social power refers to consumers’ perceived ability to influence a firm’s actions.Design/methodology/approachFollowing established scale development procedures, the construct definition and item generation preceded five studies that establish the scale’s dimensionality, psychometric properties and external, predictive and nomological validity.FindingsConsumer power was modeled as a reflective first-order, formative second-order latent construct. The consumer power scale is psychometrically sound and possesses external and discriminant validity with regard to other power-related measures. Consumer power mediates the relation between consumers’ cognitive control and consumer satisfaction and between perceived choice and emotional responses.Research limitations/implicationsThis research uses episodic recall tasks to elicit power perceptions in various contexts. Results suggest that the scale is useful in comparative and longitudinal tracking of consumers’ perceptions of power in relation to a firm.Originality/valueBuilding on a comprehensive literature review and rigorous scale development, this paper introduces a scale of consumer power that comprises a personal and a social power dimension. A critical analysis of and a predictive validity test of the scale against existing power scales highlight its unique contribution. The scale lends itself to further theory tests regarding antecedents, consequences and moderators of consumer power.

Spatio-Temporal Evolution and Driving Mechanism of Green Innovation in China

Sustainable development has become a global consensus, and green innovation is the key to promoting transition to sustainable development. The study on green innovation contributes to develop and implement green innovation policies. This paper investigates the spatio-temporal characteristics and driving mechanism of green innovation 2009–2019 in China from the perspective of economic geography based on a variety of methods such as GIS tools and Geodetector, in two dimensions of green innovation power (GIP) and green innovation growth ability (GIGA). The findings show that (1) The GIP and GIGA in China continue to increase, with obvious decreasing gradient characteristics from eastern to central and western China, extreme polarization, and obvious spatial aggregation, and the high-value regions show a change from coastal and riverine distribution to coastal distribution, with Shandong and Yangtze River Delta as the centers of high-value regions. (2) The power of the 18 driving factors on green innovation varies widely across time, and the 7 factors such as green area in urban completed area and investment in urban environmental infrastructure facilities are super interaction factors. Besides, the 5 variables of innovation input, foreign connection, economic environment, market environment and environmental regulation have different driving forces on green innovation, suggesting that the driving mechanism has changed in different periods. (3) Core factors of GIP were identified as R&D intramural expenditure and R&D personnel equivalent; important factors were identified as 5 factors such as R&D intramural expenditure in high-tech industry and FDI. Core factors of GIGA were identified as R&D intramural expenditure and added value of financial industry; important factors were identified as 4 factors such as R&D intramural expenditure in high-tech industry and GDP. (4) The 31 provinces in China were classified into 4 types of policy areas by BCG model, and proper policy suggestions were put forward. The research methods and conclusions of this paper can provide reference for green innovation policy optimization in China and other countries under similar conditions.

Joint Optimization of Received Signal Power and Signal Space Dimensions for MIMO Broadcast Channels

In Multiple-input multiple-output (MIMO) broadcast channels (BCs), the transmitter simultaneously broadcasts signals to multiple receivers at same frequency band, resulting in that the communication capacity is affected by both interference, channel fading and random noise. Although channel fading can be mitigated by transceivers, the signal-to-noise-ratio (SNR) of the practical communication system is still dynamically changing due to the randomly changing noise. Traditional MIMO transceiver optimization algorithms can not flexibly adapt to the dynamic changes of SNR, resulting in large performance degradation. In this paper, we comprehensively consider signal power and signal space dimensions of the received signal in MIMO BCs, and propose two transceiver optimization algorithms which can dynamically adapt to the variance of SNRs. In the proposed algorithms, SNR is adopted to be an adjustment factor to cope with its variance. When SNR is low, i.e, large noise, the algorithm parameters are automatically adjusted so that the signal power is preserved as much as possible to combat the loss of communication capacity caused by large random noise. Correspondingly, under the condition of high SNR environment, the algorithm parameters are adjusted automatically to effectively compress the inter-user-interference (IUI) and intra-user-inter-stream-interference (ISI) by optimizing signal space dimensions. Simulation results show that in different SNR environments, the proposed algorithms can automatically adjust the focus of optimization, so that the optimization of signal power and signal space dimensions can automatically adapt to different SNRs. Compared with traditional transceiver optimization algorithms, the proposed algorithms can improve the communication capacity within a large dynamic range of SNR.

‘I was celebrating the justice that the victims got’: exploring irreconciliation among Bangladeshi human rights activists in London

AbstractThis essay investigates transnational human rights activist networks seeking justice for war crimes committed during the Bangladesh War of 1971, especially in light of the International Crimes Tribunal in Dhaka, Bangladesh. Focusing on activists in London, it demonstrates the need to engage with transitional justice initiatives discursively and ethnographically in order to avoid losing sight of the ways in which uses of human rights concepts can veil power dimensions through universalist legalistic abstractions. The essay explores engagements with atrocities of the war by mapping the travel and uses of human rights tropes to articulate claims of justice. It showcases how in addressing the violence of the Bangladesh War, victor justice and punishment are emphasized while futures are imagined in which enemies no longer exist. In the examples, a language of justice is employed to call for prosecution, but justice is reframed so that it is equated with the impossibility of reconciling people on opposing sides during the war.

Laser additive manufacturing of bulk and powder ceramic materials: mathematical modeling with experimental correlations

PurposeThis paper aims to develop efficient and simple models for thermal distribution, melt pool dimensions and controlled phase change in the laser additive manufacturing (AM) of bulk and powder particles ceramic materials.Design/methodology/approachThis paper proposes new analytical models for the AM of bulk and powder bed ceramic materials. A volumetric moving heat source, along with the complete melting of bulk and powder particle materials, is taken into account. Different values of laser absorption coefficient in solid and liquid states have been used to investigate the phase transformation. Furthermore, the pores and voids dimensions are also included in the modeling. Theoretical predictions have been compared with the experimental analyses and finite element simulations in laser to silicon nitride and laser to alumina interaction. The analysis focuses on the impact of laser power and scanning speed on the melt pool width and depth evolution into the bulk substrate and powder bed.FindingsThis study shows that the powder particles exhibit a higher thermal distribution value than the bulk substrate because of voids in the powder layer. The laser beam experiences multiple reflections in the presence of porosity/voids, thus increasing the surface absorption coefficient, which becomes relevant with the increment in the pore/void dimension. A direct relationship has been found between the laser power and melt pool dimensions, while the scanning speed displayed an inverse relationship for the melt pool width and length. Larger melt dimensions were inferred in the case of laser–powder particle interaction compared with laser–bulk substrate interaction. A close correlation was found between the analytical simulations, experimental investigations and numerical simulation results within the range of 4%–8%.Originality/valueThis paper fulfills an identified need to develop efficient and simplified models for ceramics laser AM by taking into account different laser absorption coefficients in solid and liquid form, voids and pores dimensions and controlled phase transformation to avoid vapors and plasma formation. The limitation of the finite element simulation model is that the solution is strongly dependent on the mesh quality and accuracy directly linked to the computation efficiency and time. A finer mesh requires a longer computing time than a coarse mesh. Finite element simulations require, however, specialized skills.

Normalized Power Variance: A new Field Orthogonal to Power in EEG Analysis.

To date, electroencephalogram (EEG) has been used in the diagnosis of epilepsy, dementia, and disturbance of consciousness via the inspection of EEG waves and identification of abnormal electrical discharges and slowing of basic waves. In addition, EEG power analysis combined with a source estimation method like exact-low-resolution-brain-electromagnetic-tomography (eLORETA), which calculates the power of cortical electrical activity from EEG data, has been widely used to investigate cortical electrical activity in neuropsychiatric diseases. However, the recently developed field of mathematics "information geometry" indicates that EEG has another dimension orthogonal to power dimension - that of normalized power variance (NPV). In addition, by introducing the idea of information geometry, a significantly faster convergent estimator of NPV was obtained. Research into this NPV coordinate has been limited thus far. In this study, we applied this NPV analysis of eLORETA to idiopathic normal pressure hydrocephalus (iNPH) patients prior to a cerebrospinal fluid (CSF) shunt operation, where traditional power analysis could not detect any difference associated with CSF shunt operation outcome. Our NPV analysis of eLORETA detected significantly higher NPV values at the high convexity area in the beta frequency band between 17 shunt responders and 19 non-responders. Considering our present and past research findings about NPV, we also discuss the advantage of this application of NPV representing a sensitive early warning signal of cortical impairment. Overall, our findings demonstrated that EEG has another dimension - that of NPV, which contains a lot of information about cortical electrical activity that can be useful in clinical practice.

Soft Power of the Russian Federation: Instrumental and Perceptional Dimensions

Abstract The article analyzes specifics of instrumental and perceptional dimensions of the soft power of Russia. The analysis of these dimensions is particularly relevant in terms of studying the likelihood of the fact that Russia may continue applying the soft power strategy of long-term external influence. The main tools of the instrumental foundation of Russia’s soft power have been analyzed. Russia’s position in the rankings of well-known international rating agencies have been compared. The comprehensive studies are considered to be promising, combining detailed analysis of the soft power tools in the domestic and foreign policy strategy of the Russian Federation and the way it is perceived by different target audiences. It is concluded that foreign countries and societies perception of the soft tools application (mostly perceived as propaganda) may affect Russia’s low position in international soft power and branding rankings.

Planning for protraction

As Sino-US relations have deteriorated, concerns have grown in Washington over its ability to defeat China in a major conflict. A conflict between such peer competitors would likely become a protracted war of attrition drawing on all dimensions of national power, but this reality has yet to receive a sufficient degree of analytical attention. In this Adelphi book, Iskander Rehman provides a historically informed and empirically grounded study of protracted great-power war, its core drivers and characteristics, and an examination of the elements that have most often determined a competitor’s long-term strategic performance. A detailed analysis of the contemporary Sino-US rivalry assesses how both parties might fare in the event of a protracted war, while highlighting some of its key significant differentiating aspects – most notably its nuclear and cyber dimensions.

Perceived legitimacy of agricultural transitions and implications for governance. Lessons learned from England’s post-Brexit agricultural transition

It is widely recognized that there is a global need for a transition towards more sustainable forms of agriculture. In order for such a transition to be socially sustainable, its input (problem and goal formulation), output (policy instruments), and throughput (processes) need to be perceived as legitimate. However, we currently know relatively little on how to legitimize normatively shaped transition processes and their outcomes. We aim to address this knowledge gap by examining how the governance of agricultural transitions can be shaped to improve the perceived legitimacy of the transition. Through a combined lens of normative and sociological approaches to legitimacy we investigate the English post-Brexit agricultural transition as a crucial case-study. Building on a policy analysis and semi-structured interviews we find that in order to create perceived legitimacy of agricultural transitions, both in the English case and for agricultural transitions generally, clarity and diversity in design is essential. In addition, in order to take account of the normative and political nature of agricultural transitions, our study highlights the importance of a broad problem formulation, a diverse mix of instruments, and a process that is transparent and includes stakeholders in a meaningful and equal way. We conclude that a combined lens of normative and sociological legitimacy forms a useful framework for future research to critically evaluate the normative and power dimensions of transition processes. In addition, it can support governments in their efforts to develop policies for agricultural sustainability transitions that will be accepted by society.

The Interplay of Alcohol and Wellbeing in the Workplace: Combining Soft Systems Methodology and Foucauldian Approach

This paper focuses on the topic of alcohol and wellbeing in contemporary work organisations. It explores the relationship between stakeholders’ viewpoints regarding alcohol in the workplace and how they have shaped organisational practices regarding wellbeing. The work of Michel Foucault is used to explore these issues. The notions of power, knowledge and discipline are identified as key Foucauldian themes that offer an alternative understanding of how discourses on alcohol are shaped in the United Kingdom workplace. The paper combines certain stages of Checkland’s Soft Systems Methodology and Foucault’s Poststructuralist approach in addressing the topic. Foucault’s method of analysis, particularly archaeology and genealogy, is used to explore how and why certain discourses surrounding alcohol in the workplace become dominant over time. Qualitative cases with semi-structured interviews in knowledge-intensive firms were adopted to capture contrasting, varied experiences and perceptions of these organisational actors and shed light on alcohol and wellbeing and its relationships with the power dimension.

Cancel culture and the consumer: A strategic marketing perspective

ABSTRACT Celebrities and brands have been perceived to be more powerful in the consumer-celebrity-brand relationship. Of late, this power balance has been reversed with the presence of social media allowing consumers to wield this tool over celebrities and brands in the wake of a negative episode, such as an objectionable and controversial incident. This causes celebrities and brands, referred to as the influence target, to be cancelled. The power within relationships theory is used to examine the consumer cancel culture framework. A lack in power dimensions such as warmth and competence cause consumers to experience a decline in their attachment, resulting in cancelling the influence targets more so if the attachment style exhibited by the consumer is anxious and avoidant. This is the first paper in consumer-behaviour to explore this phenomenon from an academic perspective and has practical implications for protecting celebrities and brands from cancel episodes.

Chaotic Power Division Multiplexing for Secure Optical Multiple Access

This paper proposes a novel chaotic power division multiplexing (CPDM) for secure optical multiple access. The proposed CPDM can not only improve spectral efficiency and the user number by multiplexing spectrally overlaid OFDM signals at different power ratio, but also ensure the information security of the users by implementing chaotic encryption on the physical layer. The key space of the encryption scheme is up to <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">${10^{98}}$</tex-math></inline-formula> , which can effectively resist the illegal acceptance. Furthermore, to meet future data traffic and multiple access demands, we first explore the beneficial combination of power dimension and mode dimension. A 30 Gb/s secure chaotic power division multiplexing and mode division multiplexing passive optical network (CPDM-MDM-PON) transmission over 5 km weakly coupled few-mode fiber (FMF) is experimental demonstrated. Experimental results show that, the proposed PON system has the appealing potential to attain high spectral efficiency and large traffic capacity and serve more users. The nonlinearity transmission impairments of single mode fiber and FMF are also investigated in this paper.

Nigeria’s Democracy Promotion in Africa: Hard, Soft or Smart Power Stratagem?

Democracy promotion is undoubtedly one of Nigeria’s most important foreign policy objectives in Africa. Indeed, it has featured in the state’s foreign policy across successive administrations including military and civilian regimes. A fundamental question explored by this article is the dimension of power Nigeria deploys in its foreign policy objective of democracy promotion in Africa. Is it hard or soft, or a combination of the two (smart power)? Using three case studies – Sierra Leone, São Tomé and Príncipe and The Gambia – the article reveals that Nigeria has deployed all three dimensions of power. While this reflects the peculiar circumstances of these particular states in constitutional crisis, Nigeria’s domestic situation, including the type of political system (democratic or authoritarian) and the personality of the president at a given time, as well as trends in the global arena, are also germane. By its very nature, democracy promotion depends on a state’s soft power as the admirable domestic values of the soft power state attract other states to emulate its democratic practices. However, as the case study of Nigeria shows, a state can deploy soft, hard or smart power in its quest to promote democracy depending on the domestic circumstances of both the soft power and recipient states.
