Although many towns repaired, restored or destroyed the ruins of Civil War sieges, there are a number of towns, villages and hamlets which still clearly bear marks of the conflict. By focusing on Colchester, this article will highlight how sites affected by the wars remained and survived in the local consciousness throughout the following centuries. This article traces the uses of such sites in the urban landscape in the eighteenth and nineteenth centuries to assess the long-term impact of the war on towns in the British Isles. By examining Colchester in 1648, the article will show how political parties, parishes, tourists and businesses all derived value from the sites of the siege centuries after it had ended.

Clay minerals are effective adsorbents for the remediation of pesticides in wastewater due to their large superficial areas and excellent cation-exchange capabilities. However, this adsorption effect can be reduced by the accumulation of adsorbents on clay minerals, amongst other problems. Therefore, in this study, montmorillonite (Mnt) modified by layered double hydroxide (LDH) with different loading amounts was successfully prepared using an in situ method. The results from X-ray diffraction, Fourier-transform infrared spectrometry, Brunauer–Emmet–Teller (BET) and scanning electron microscopy analyses revealed that LDH structures were successfully combined with the Mnt layer and formed a porous structure. However, excess LDH still caused the aggregation and accumulation of layers. The adsorption performance of LDH@Mnt for atrazine (ATZ) and paraquat (PQ) was investigated, and the removal efficiency of the LDH@Mnt composite was higher than those of Mnt and LDH alone. The kinetic study revealed that the adsorption process fitted the pseudo-second-order model and internal diffusion model, and 3-LDH@Mnt had the greatest absorbability efficiency for both ATZ and PQ, indicating the adsorption process was controlled by the number of active sites of the adsorbent. The generalized Langmuir model accurately characterized the adsorption process of ATZ and PQ elimination in the adsorption isotherm investigation, indicating that the adsorption energies of the active sites on the adsorbents were different. 3-LDH@Mnt had better absorbability performance for ATZ/PQ, and the sorption capacities were 7.03 and 91.9 mg g–1, respectively. According to site energy distribution theory, the amount of sorption sites of the composite adsorbent was large and the average adsorption energy was high, both of which being beneficial for the adsorption of ATZ and PQ. The effects of pH, coexisting anions and reuse experiments were also tested, indicating that the LDH@Mnt composite possessed high adsorption stability. This excellent removal performance represents a promising strategy for the remediation and elimination of pesticide contaminations from the environment.

Research into young learners' metalinguistic awareness has led to both definitions of the construct and key findings about its role in children's cognitive and linguistic development. I briefly summarise this research before introducing two established theoretical models that can help us understand the concept of metalinguistic awareness more broadly: Ellen Bialystok's classic dichotomy of analysis of knowledge and control of processing, and Rod Ellis's notion of explicit (second language) knowledge. This is followed by an overview of measures of metalinguistic awareness that have been used in empirical studies to date as well as an illustration and critique of selected measures. As a result, I propose a model that combines features of the two previous frameworks by conceptualising knowledge representations and processes in terms of (1) how implicit/explicit and (2) how specific/schematic they are. I explain this model to illustrate how it can serve as a useful thinking tool. In particular, I argue that the model not only allows us to theorise measures of metalinguistic awareness more clearly and easily, but that it can also capture tasks aimed at assessing other linguistic and cognitive abilities. The article concludes with a brief outlook on future research into metalinguistic awareness.

Despite the salutary effects of mask wearing broadly recognized during the COVID-19 pandemic, little is known about the consequences of wearing masks in the workplace. The current research raises the question of whether and how mask wearing may impact employees' emotional well-being at work. Drawing on emotion regulation theory (e.g., Gross, 1998, 2015), we propose that mask wearing enables employees to adopt more authentic emotional displays, which in turn decreases emotional exhaustion. Furthermore, guided by the social interaction model of emotion regulation (Coté, 2005), we further posit that for employees whose work requires more frequent face-to-face interaction, the positive impact of mask wearing on emotional exhaustion becomes more significant. Across a pilot study and a three-wave field survey, we find support for this hypothesized model. Implications of these findings for future theorizing and research on mask wearing are discussed.

The war in the former Yugoslavia produced many highly trained and experienced combatants, some of whom engaged not only in a variety of organized criminal activities such as the illicit trade of natural resources, trafficking and corruption, but also war crimes. In the post-war environment various criminal groups took advantage of post-conflict transition conditions which enabled them to be transformed into legitimate legal entities. The failure to investigate and hold to account those involved in criminal activity meant that demobilized soldiers turned to highly profitable, legally constituted private military and security companies (PMSCs). This is coupled with poorly designed security sector reforms that often fail to enhance effective and accountable security that is respectful of human rights. In recent years, similar transformations of many former combatants and criminal groups into legitimate PMSCs around the globe have raised new concerns about their growing activities across different sectors. This article uses the former Yugoslavia as an example from which to highlight some of the increasingly common problems posed by the creation of private military and security providers globally, as a result of the current uncoordinated processes to prevent armed conflicts. The article reflects on the need to avoid smart sanctions and use other foreign policy tools, while calling for an integrated approach to security sector reform and transitional justice that is necessary for sustainable peace.
