From slavery and colonialism to Black Lives Matter: New mood music or more fundamental change
No full textPURPOSE 2020 has proved to be a challenging year. In addition to the challenges of Covid 19, yet again, the USA has witnessed police brutality leading to the death of a Black man, George Floyd. The Black Lives Matter movement, founded in the US but now an international organisation which challenge white supremacy and deliberate harm against Black people, mobilised hundreds of thousands of people to take to the streets, across the globe. Increasingly, the protests focus not only on George Floyd’s murder, but also the continued failure to challenge the celebrity of those involved in the transatlantic slave trade and European imperialism. In this article, I will contend that many organisations are now re-examining their association with these historical wrongs against Black Africa and its diaspora. Further, I will contend but that the failure to highlight the role of Black chattel slavery and imperialism in the accumulation of economic, commercial and political benefits reaped by the global north is a source of shame for many firms and institutions but also, universities. APPROACH I have reviewed the online media for the latest developments in response to Black Lives Matter’s George Floyd campaign in 2020, and reviewed literature on the link between European global ambition and its impact on the Americas and sub-Saharan Africa. FINDINGS Internationally, there is a discernible change in outlook towards the importance of the evils of slavery and colonialism on the Black experience today. These small steps will require scholars to embark on a fresh reexamination of race, society and work. For decades, the slave trade and colonialism were issues rarely raised in government, firms and business schools. This will inevitably change, especially in those countries that are the main beneficiaries of Black chattel slavery and colonial exploitation. Much EDI practice is fundamentally, tokenism. A root and branch reappraisal will be needed to created more effective EDI policy and practice in support of race equality and anti-racism
A review: Reaction mechanism and strength of slag and fly ash-based alkali-activated materials
No full textAlkali-activated materials (AAM) are known to be environmentally friendly alternatives to cement-based materials because they can potentially reduce greenhouse gas emissions and reutilize industrial by-products/wastes. To study the factors influencing the strength of slag based alkali-activated materials (BFS-AAM), fly ash based alkali-activated materials (FA-AAM), slag, and fly ash-based alkali-activated materials (BFS/FA-AAM), and clarifying their reaction mechanisms, this paper reviews current knowledge about the mechanical properties and the reaction mechanisms of BFS-AAM, FA-AAM, and BFS/FA-AAM. The precursor requirements and the strength control factors are summarized. The control factors for the strength of BFS/FA-AAM are the BFS/binder ratio, the Na2O/binder ratio, the SiO2/Na2O ratio, and the w/binder ratio. Ion concentrations, determined by these control factors, play a decisive role in the development of strength. Generally, the strength is proportional to the BFS/FA ratio. The optimal values of the Na2O/binder ratio of BFS-AAM and FA-AAM are between 5.5% and 8% and between 7 and 10%, respectively. The optimal values of the SiO2/Na2O ratio of BFS-AAM and FA-AAM are between 0.85 and 1.4 and between 0.6 and 1, respectively. Increasing the w/binder ratio will only benefit workability but will affect the strength negatively. A w/binder ratio of around 0.4 may strike a balance between strength and workability.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Materials and Environmen
AAM - Politically Motivated Consumer Boycotts
No full textThis project contains the Author Accepted Manuscript (AAM) of the article accepted for publication in the Journal of Consumer Marketing. The study introduces Politically Motivated Consumer Boycotts (PMCBs) as a distinct form of political consumerism that emerges in response to brands’ perceived political alignment—particularly in polarized societies. Drawing on social movement theory and political consumerism literature, it examines the emergence and motivations behind such boycotts through a qualitative case study of the 2017 Pınar boycott in Turkey. The manuscript includes interview data, digital platform analysis, and a multi-level framework connecting macro-political context, digital mobilization, and consumer motivation.

Kaidah ‘Aam, Khas dan Takhshish dalam Hukum Keluarga
No full textPronunciation is an expression with which one thing can be understood. However, the meaning of the pronunciation will be greatly influenced by something that goes hand in hand with it. The meaning of lafaz can mean aam (general), special (special), and Takhsis. This paper will explore how lafaz can mean am, distinctive, and takhsis, accompanied by an explanation of the rules/provisions that can influence it. This study uses the library research method, where later the author will explain the discussion by including examples from the Koran and Hadith to find a clearer understanding of a syara' proposition. The results of this study found that there are three family laws that have gone through the stages of the takhshish rule, where the existing 'aam' pronunciation from the syara' proposition is taken so that the meaning becomes narrower or limited.Lafaz merupakan suatu ungkapkan yang dengannya dapat dipahami satu hal.

A review: The strength influence factors of slag and fly ash based alkali activated materials
No full textAlkali-activated materials(AAM) are known to be environmentally friendly alternatives to cement-based materials because they can potentially reduce greenhouse gas emissions and reutilize industrial by-products. However, the application of AAM is still limited by the lack of mixture design regulation. Unlike cement, the very different chemical composition of the precusors and alkaline activators may result in a very fluctuating strength. In order to study the factors influencing the strength of slag and fly ash-based alkali-activated materials (BFS/FAAAM), and clarify their reaction mechanism, this paper reviews current knowledge about the mechanical properties and the reaction mechanisms of BFS/FA-AAM. The control factors of strength are BFS/binder ratio, Na2O/binder ratio, and SiO2/Na2O ratio. The ion concentrations, determined by these control factors, play a decisive role in the development of strength. Generally, the strength is proportional to the BFS/binder ratio. The best strength could be obtained at the optimum values of Na2O/binder ratio, and SiO2/Na2O ratio. The optimum values of the SiO2/binder ratio of BFS-AAM and FA-AAM are between 5.5%-8% and between 7-10%, respectively. The optimal values of the SiO2/Na2O ratio of BFS-AAM and FA-AAM are between 0.85-1.4 and between 0.6-1, respectively. For BFS/FA-AAM, the optimum ratio is still unknown. Further study is needed to investigate the effect of control factors on the mechanical properties of BFS/FA-AAM
Effect of Activator Solutions on the Thixotropic Behavior of Alkali-Activated Slag Concrete
No full textAlkali-activated material (AAM) is developed as a green alternative binder to replace Portland cement (PC) in the construction field. However, the large-scale application with AAM concrete is limited so far, with the insufficient knowledge of rheological behavior being a major obstruct. Thixotropy of concrete is of great interest, which can be helpful to predict various early-age performances. The current study dedicates to evaluating the thixotropy of alkali-activated slag (AAS) concrete mixtures with different silicate and water content in activator solutions. In specific, the silicate modulus (Ms) and water to binder (w/b) ratio have been varied. The thixotropic index calculated by the initial and equilibrium shear stress from the stress growth test, as well as the breakdown area obtained by applying different shear speeds were used to evaluate the thixotropy of AAM concrete. Results indicate a good correlation between different approaches. It was found that an increase in Ms led to more pronounced thixotropic behaviors in AAS concrete due to the rapid nucleation and accumulation of early hydration products, resulting in significant increases in peak torque values and slight reductions of torque at equilibrium. Besides, the concrete thixotropy gradually declined by applying a higher w/b ratio.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Materials and Environmen
Advances in using municipal solid waste incineration (MSWI) bottom ash as precursor for alkali-activation materials: A critical review
No full textThe pursuit of low-carbon binders as alternatives to Portland cement has sparked interest in developing alkali-activated materials (AAM).1 Using municipal solid waste incineration (MSWI) bottom ash as precursor for AAM has attracted increasing attention as it offers a sustainable, resource-efficient solution to mitigate the environmental impacts associated with the landfill of MSWI bottom ash. However, the varying properties of MSWI bottom ash present challenges in its wide application as AAM precursor. This review provides a comprehensive overview of advances in MSWI bottom ash-based AAM,2 with a particular focus on the relationship between the physicochemical properties of MSWI bottom ash and the engineering properties of MSWI bottom ash-based AAM. This work consolidates the most up-to-date understanding of the reaction mechanism and reaction products of MSWI bottom ash, along with the existing knowledge about mix design and microstructure formation of MSWI bottom ash-based AAM. The factors influencing the engineering properties of MSWI bottom ash-based AAM are detailed, and the environmental impacts of MSWI bottom ash-based AAM are reviewed. Ultimately, this review provides recommendations for the standardized and effective use of MSWI bottom ash as AAM precursor.Materials and Environmen
Reactivity and leaching potential of municipal solid waste incineration (MSWI) bottom ash as supplementary cementitious material and precursor for alkali-activated materials
No full textThis work evaluated the reactivity and leaching potential of municipal solid waste incineration (MSWI) bottom ash as supplementary cementitious material (SCM) and precursor for alkali-activated materials (AAM). The chemical composition of the amorphous phase in MSWI bottom ash was found to be in the same range as that of Class F coal fly ash. The reactivity of MSWI bottom ash as SCM and AAM precursor was tested to be much lower than that of blast furnace slag, but similar to that of Class F coal fly ash. The method of thermodynamic modeling was found useful in providing references for the mix design of MSWI bottom ash-based AAM. Grinding MSWI bottom ash into powder for the application of SCM and AAM precursor increased its leaching potential. Based on the findings of this study, recommendations were provided on how to use MSWI bottom ash to prepare blended cement pastes and AAM.Materials and EnvironmentDC systems, Energy conversion & Storag
