Quaternary environments on the Arabian Peninsula shifted between pronounced arid conditions and phases of increased rainfall, which had a profound impact on Earth surface processes. However, while aeolian sediment dynamics are reasonably well understood, there is a lack of knowledge with regard to variability in the fluvial systems. Presented here are the findings from several locations within wadi drainage systems to the west of the Hajar Mountains (United Arab Emirates). The performance of optically stimulated luminescence dating using a customized standardized growth curve approach is investigated, showing that this approach allows reliable determination of ages by reducing the machine time required. Three main periods of fluvial activity occurred at 160–135, 43–34, and ca. 20 ka. Additional ages fall into the latest Pleistocene and Late Holocene. None of the ages coincides with major wet periods in SE Arabia that have been identified in stalagmites and by the deposition of lake sediments. It is shown that fluvial activity was partly contemporaneous (within the given time resolution) with phases of aeolian deposition and was almost continuous, but likely sporadic, during the Middle to Late Pleistocene. This highlights the need for regionally defined paleoenvironmental records to fully understand the response of dryland systems to long-term climatic change.

Summary
This chapter outlines an approach to the study of categorisation in language practice grounded in the work of American sociologist Harvey Sacks known as Membership Categorisation Analysis. MCA proposes that categories and their associated ‘normative orders’ are not simply stored in people’s heads; they are used as part of the accomplishment of practical tasks in various social settings. Thus, MCA focuses on how categories are used to do things within talk and text, such as criticising, complaining, praising, encouraging, inviting, commending, blaming, and so on. Moreover, we also propose that power relations can be central to the study of categories. We demonstrate this in a political context through analysis of a political speech made by the previous British Prime Minister, Theresa May. We show that May’s category-based reasoning about social injustice was used to appeal to a sense of social solidarity and moral responsibility of ‘the fortunate’ to help the ‘less fortunate’ in society. We conclude that MCA has value for students and practitioners of language because no other approach comes as close to the study of how categories are used in talk and text in real-life situations.

Background:
The use of assessment tools has been shown to improve the inter-rater reliability of capacity assessments. However, instrument-based capacity assessments of people with dementia face challenges. In dementia research, measuring capacity with instruments like the MacArthur Competence Assessment Tool for Treatment (MacCAT-T) mostly employ hypothetical treatment vignettes that can overwhelm the abstraction capabilities of people with dementia and are thus not always suitable for this target group. The primary aim of this study was to provide a standardized real informed consent paradigm that enables the dementia-specific properties of capacity to consent to treatment in people with dementia to be identified in a real informed consent process that is both externally valid and ethically justifiable.
Methods:The sample consisted of 53 people with mild to moderate dementia and a group of 133 people without cognitive impairment. Rather than using a hypothetical treatment vignette, we used a standardized version of the MacCAT-T to assess capacity to consent to treatment with cholinesterase inhibitors in people with dementia. Inter-rater reliability, item statistics, and psychometric properties were also investigated.
Results:Intraclass correlations (ICCs) (0.951–0.990) indicated high inter-rater reliability of the standardized real informed consent paradigm. In the dementia group, performance on different items of the MacCAT-T varied. Most people with dementia were able to express a treatment choice, and were aware of the need to take a tablet. Further information on the course of the disorder and the benefits and risks of the treatment were less understood, as was comparative reasoning regarding treatment alternatives.
Conclusion:The standardized real informed consent paradigm enabled us to detect dementia-specific characteristics of patients’ capacity to consent to treatment with cholinesterase inhibitors. In order to determine suitable enhanced consent procedures for this treatment, we recommend the consideration of MacCAT-T results on an item level. People with dementia seem to understand only basic information. Our data indicate that one useful strategy to enhance capacity to consent is to reduce attention and memory demands as far as possible.

Introduction: Tobacco use is common among people who have been in prison. The relationship between social stressors, risky health behaviours, and smoking cessation has not been studied in people recently released from prison. Studying this relationship could yield information that guides strategic and cost-effective tobacco cessation interventions for an under-resourced population.
Methods: One hundred and forty-three smokers were interviewed 7 to 21 days after they had been released from USA prisons. Independent variables included employment status, housing security, relationship problems, educational achievement, risky drinking behaviour, recent drug use, history of drug dependence, and depression. The primary outcome was ‘trying to quit smoking.’ Data were analysed using Pearson chi-square tests and single and multivariable logistic regression models.
Results: Of those who had to quit smoking due to tobacco-free prison policies, 98% reported relapsing on tobacco after release. Trying to quit smoking was associated with the absence of risky drinking behaviour in the past 30 days (adjusted odds ratio [AOR] 6.44, 95% confidence interval [CI] 2.02–20.48).
Conclusions: The absence of risky drinking behaviour is associated with trying to quit smoking among people recently released from prison. Further research may determine whether interventions addressing risky alcohol use can reduce smoking relapse.

In this paper we contribute to the body of work on agency and institutional transmission by proposing two new concepts: distributed agency and dialogue. Distributed agency is a companion concept to that of ‘institutional entrepreneurship’. Whilst institutional entrepreneurship emphasizes the deliberate institution-building by a select few, distributed agency highlights the emergent institution-building that involves any and every organizational member. In turn, dialogue supplements the models of institutional diffusion by drawing attention to the situated interactions between the ‘champions’ and the ‘recipients’ of institutional innovations, to the frictions that accompany institutional transmission, and to the deviations that emerge from those interactions. We use these concepts to analyze the micro-discursive processes during a crucial event in the institutionalization of a new organizational template in a UK public–private partnership. We found that the implementation hinged upon enabling the audience (i.e. the employees expected to apply the template in their work) to act as agents (hence, distributed agency) by engaging in a dialogue that sought to define the audience's identity vis-à-vis coercive pressures, articulate and address its interests, and recognize its rights to modify the template to suit the local circumstances.

Infectious diseases are among the main causes of death and disability in developing countries, and they are a major reason for the health disparity between rich and poor countries. One of the reasons for this public health tragedy is a lack of lifesaving essential medicines, which either do not exist or badly need improvements. In this article, we analyse which of the push and pull mechanisms proposed in the recent literature may serve to promote research into neglected infectious diseases. A combination of push programmes that subsidise research inputs through direct funding and pull programmes that reward research output rather than research input may be the appropriate strategy to stimulate research into neglected diseases. On the one hand, early-stage (basic) research should be supported through push mechanisms, such as research grants or publicly financed research institutions. On the other hand, pull mechanisms, such as prize funds that link reward payments to the health impacts of effective medicines, have the potential to stimulate research into neglected diseases.

Inconsistent results exist from human and animal studies for Se and methionine (Met) regarding their influence on homocysteine (HCys) and cholesterol (Chol) metabolism. To elucidate these contradictions, sixty-four weanling albino rats were divided into eight groups of 8, and were fed diets containing four different Se levels (15, 50, 150 and 450 μg/kg) either in combination with the recommended Met level of 3 g/kg (C15, C50, C150 and C450) or with an increased Met concentration of 15 g/kg (M15, M50, M150 and M450) for 8 weeks. Plasma HCys was twofold higher in the Se-supplemented C groups than in group C15. Met addition also doubled plasma HCys compared with the respective C groups. In contrast, the expression of the key enzymes of glutathione biosynthesis in the liver was significantly lowered by Se and in particular by Met. Liver Chol concentration was significantly higher in all the Se-supplemented C and M groups than in groups C15 and M15. Plasma Chol was, however, lowered. The uninfluenced expression of sterol-regulatory element-binding protein 2 and of hydroxymethyl-glutaryl-CoA reductase, the increased LDL receptor expression and the reduced expression of the hepatobiliary Chol exporter ATP-binding-cassette-transporter 8 (ABCG8) by Se and/or Met explain these findings. We conclude that the elevation of plasma HCys in rats by Se and Met results from a higher export into plasma. The fact that Se in particular combined with Met increases liver Chol but reduces plasma Chol should be addressed in future investigations focussing on the regulation of ABCG8, which is also selectively involved in the reverse transport of phytosterols in the small intestine.

Maternal supplementation with long-chain PUFA, to improve infant neurological development, might cause additional increase of oxidative stress. Pregnant women aged 18–41 years were randomised into one of four supplementation groups. From week 22 on, they received supplements containing either modified fish oil (n 69), 5-methyl-tetrahydro-folate (n 65), both (n 64), or placebo (n 72). Plasma Trolox-equivalent antioxidative capacity (TEAC), concentrations of α-tocopherol, retinol, β-carotene, free thiol groups, uric acid and thiobarbituric acid-reactive substances (TBARS) were determined at weeks 20 and 30 and at delivery. The studied antioxidants showed no significant differences between the four supplementation groups. At week 30 plasma TBARS levels were found to be significantly higher in the fish oil group (0·80 (sem 0·04) μmol/l) than in the folate (0·67 (sem 0·03) μmol/l; P = 0·024) and control (0·69 (sem 0·04) μmol/l; P = 0·01) groups. Concentrations of retinol and free thiol groups decreased during pregnancy, whereas uric acid increased and β-carotene as well as TEAC showed only minor changes. Fish oil supplementation during the second half of pregnancy appears not to decrease antioxidant status. The increased TBARS levels at week 30 may indicate a period of increased oxidative stress in plasma at this time.

As the debate throughout the eighties has concluded, the efforts of governments to intervene at the firm level has largely been disappointing. Using two examples drawn from the British experience, Rover and Inmos, this paper offers an analysis as to why the Government has encountered difficulties when it has sought to intervene in a strategic fashion. Essentially, public policy makers lack adequate mechanisms to intervene effectively in technology-based companies. Locked out of the knowledge base of the firm, inappropriate financial control is imposed which reinforces the ‘outsider’ status of the Government. Having addressed the limitations of strategic intervention, the paper, drawing on the comparative experience of other countries, then goes on to address how this policy boundary might be pushed back in the long term.

Summary
GLOBALIZATION AND NETWORKS
In this chapter, we explore globalization through networks. Of course, globalization can be described in terms of networks of trade between countries and as executed by multinational corporations (Breiger 1981; Chase-Dunn and Grimes 1995; Kim and Shin 2002). And fisheries ecosystems have long been characterized in terms of networks of predator and prey relationships between taxon or species (e.g., Cohen et al. 1993; Gaedke 1995; Krause et al. 2003). But here we will explore how human social networks mediate between global economic exchanges and the dynamics of aquatic ecosystems. Thus we extend critiques of the globalization literature for lack of attention to individual agency (e.g., Schechter 1999:62) by calling attention to the effects of human relationships in globalization. Ultimately, our focus allows us to integrate theories related to social networks (e.g., social capital) as well as inform policy and management of and research on fisheries and their associated ecosystems.
What is globalization?
We define globalization as an increase in the rate of exchange of resources and information across geographic regions and cultures. Though communities have been interdependent through trade as long as people have traversed the oceans, our current awareness of globalization suggests that we are increasingly globalized – that the resources and related actions in distant regions of the world have an unrivaled immediacy in the lives of most people (Harrison 1996; Kim and Shin 2002; One World 2007).

Several electrorheological (ER) materials systems composed of amorphous ceramic powders dispersed in light paraffin oil were developed to determine if relationships among ER activities, dielectric properties, compositions, porosities, and oxide species could be identified. The results of the studies suggested that trends among ER activity, dielectric phenomena, and alkali metal species existed. The aluminosilicate powders developed with various alkali metals showed that the ER activity increased as the activation energy decreased. The sodium aluminosilicate appeared to have the greatest ER activity and the lowest activation energy, while the cesium aluminosilicate displayed the weakest ER response, but had the highest activation energy. The thermodielectric responses of the different oxide materials systems developed with sodium showed that the mechanisms contributing to the dielectric dispersions had similar activation energies; however, the magnitudes of the recorded ER activities varied, and thus a direct correlation was not apparent. In addition, studies conducted with ER materials composed of sodium aluminosilicate powders of varying porosities showed that ER activities increased with increasing porosity. Furthermore, the analysis of the results of the thermodielectric and rheological studies of the different amorphous materials ER systems suggested that these materials may have an optimal stimulus frequency/temperature for ER activity.
