"But no one told me it’s okay to not drink": a qualitative study of young people who drink little or no alcohol

Young people’s drinking is a matter of social, media and political concern and the focus of much policy activity within the UK. Little consideration has been given to the fact that some young people choose to drink little or not all and our knowledge and understanding of their choices and how they manage not drinking is limited. Nor has much attention been paid to the possibility that the insights of young light and non-drinkers could be useful when thinking about how to change the prevailing drinking culture, but if we are to gauge and engage with the current culture of consumption then we need to understand all parts of it (Pattenden et al., 2008). This qualitative study of young people (aged 16-25) who drink little or no alcohol aimed to further understanding of their lives and choices. The results highlight that choosing not to drink or drink lightly is a positive choice made for diverse reasons with the strongest messages and influences coming from real life observations. Young people develop strategies to manage not drinking or drinking lightly. Alcohol education messages need to present not drinking as a valid option to young people, parents and society more broadly

Ethnicity and alcohol: a review of the UK literature

This literature review draws together recorded drinking patterns among minority ethnic groups in the UK over the last 15 years and considers the evidence for service provision and support. A recommendation in implementing the Government’s alcohol strategy, Safe. Sensible. Social. is to assess the need for and develop provision for black and minority ethnic groups. This need is heightened by the growing minority ethnic population and changes in consumption levels that may emerge over generations. The review explores differences in drinking patterns by ethnicity and the cultural and social contexts around which the use of alcohol is established and maintained. This review: • describes drinking levels as reported in national surveys and local research; • considers processes and infl uences that help to explain why drinking rates among ethnic groups in a new country may change over time; • examines help-seeking, support and service provision for minority ethnic groups; • examines the extent to which services are equipped to respond to the needs of minority ethnic groups

A positive choice: young people who drink little or no alcohol

This study examined the lives and choices of young people (aged 16-25) living in the UK who drink little or no alcohol. Current policy is directed at young people who drink alcohol with little attention paid to the insights of those who drink lightly or not at all. The influences that shape young people’s decisions and how their choices and patterns of consumption affect their lives were explored through interviews. The report: • examines current drinking patterns and identifies five ‘drinking types’; • highlights that choosing not to drink alcohol or to drink lightly is a commonplace and positive choice; • explores the influences and experiences that led young people to their choices and identifies three ‘narratives’ encapsulating their journeys; • considers the strategies and responses young people employ to manage not drinking or drinking lightly; and • critically examines the widely held assumption that drinking is part of‘growing up’ and discusses how ‘not drinking’ could be supported as a valid choice

Teenage drinking and interethnic friendships.

This report explores the links between young people’s interethnic friendships and their drinking patterns and behaviours. Britain is a multicultural society, but little is currently known about if, and how, young people mix with friends from different ethnic backgrounds and the potential impact of this on drinking attitudes and behaviours. Research was undertaken to examine these links using quantitative and qualitative methods among a sample of 14-and 15-year-olds in diverse locations in London and Berkshire. The report: • explores the intra- and interethnic mix of young people’s friendship groups as described by young people in questionnaires and interviews; • analyses how drinking patterns vary by ethnicity, religion and gender; • investigates the links between young people’s background characteristics, their friendship groups (including the ethnicity of friends) and their reported drinking rates; and • looks at the implications of the findings, including recommendations for harm reduction based on education and peer support programmes

Quantitative assessment of sewer overflow performance with climate change in northwest England

Changes in rainfall patterns associated with climate change can affect the operation of a combined sewer system, with the potential increase in rainfall amount. This could lead to excessive spill frequencies and could also introduce hazardous substances into the receiving waters, which, in turn, would have an impact on the quality of shellfish and bathing waters. This paper quantifies the spilling volume, duration and frequency of 19 combined sewer overflows (CSOs) to receiving waters under two climate change scenarios, the high (A1FI), and the low emissions (B1) scenarios, simulated by three global climate models (GCMs), for a study catchment in northwest England. The future rainfall is downscaled, using climatic variables from HadCM3, CSIRO and CGCM2 GCMs, with the use of a hybrid generalized linear–artificial neural network model. The results from the model simulation for the future in 2080 showed an annual increase of 37% in total spill volume, 32% in total spill duration, and 12% in spill frequency for the shellfish water limiting requirements. These results were obtained, under the high emissions scenario, as projected by the HadCM3 as maximum. Nevertheless, the catchment drainage system is projected to cope with the future conditions in 2080 by all three GCMs. The results also indicate that under scenario B1, a significant drop was projected by CSIRO, which in the worst case could reach up to 50% in spill volume, 39% in spill duration and 25% in spill frequency. The results further show that, during the bathing season, a substantial drop is expected in the CSO spill drivers, as predicted by all GCMs under both scenarios

A role for NPY-NPY2R signaling in albuminuric kidney disease

Albuminuria is an independent risk factor for the progression to end-stage kidney failure, cardiovascular morbidity, and premature death. As such, discovering signaling pathways that modulate albuminuria is desirable. Here, we studied the transcriptomes of podocytes, key cells in the prevention of albuminuria, under diabetic conditions. We found that Neuropeptide Y (NPY) was significantly down-regulated in insulin-resistant vs. insulin-sensitive mouse podocytes and in human glomeruli of patients with early and late-stage diabetic nephropathy, as well as other nondiabetic glomerular diseases. This contrasts with the increased plasma and urinary levels of NPY that are observed in such conditions. Studying NPY-knockout mice, we found that NPY deficiency in vivo surprisingly reduced the level of albuminuria and podocyte injury in models of both diabetic and nondiabetic kidney disease. In vitro, podocyte NPY signaling occurred via the NPY2 receptor (NPY2R), stimulating PI3K, MAPK, and NFAT activation. Additional unbiased proteomic analysis revealed that glomerular NPY-NPY2R signaling predicted nephrotoxicity, modulated RNA processing, and inhibited cell migration. Furthermore, pharmacologically inhibiting the NPY2R in vivo significantly reduced albuminuria in adriamycin-treated glomerulosclerotic mice. Our findings suggest a pathogenic role of excessive NPY-NPY2R signaling in the glomerulus and that inhibiting NPY-NPY2R signaling in albuminuric kidney disease has therapeutic potential. Chronic kidney disease (CKD) is a major global healthcare concern, affecting over 10% of the general population, and frequently occurs secondary to other systemic disorders including diabetes, obesity, hypertension, and the metabolic syndrome. A common early hallmark of CKD is albuminuria, which not only reflects damage to the glomerular filtration barrier (GFB) in the kidney but also is an important independent risk factor for the progression to end-stage renal failure and cardiovascular disease (1⇓–3). Thus, strategies to prevent albuminuria have important therapeutic potential, particularly in the early stages of CKD progression. Podocytes are highly specialized epithelial cells of the glomerulus, lining the urinary side of the filtration barrier. Owing to their complex, dynamic structures and their ability to secrete (and adapt to) a number of growth factors, these cells have a central role in filtration barrier maintenance (4). As such, podocyte damage is a key driver of albuminuria and glomerular disease in numerous settings and occurs early in the pathogenesis of many albuminuric conditions (5⇓⇓⇓–9). While it is well-established that podocyte damage is a major cause of albuminuria (8), the pathways and molecules involved in podocyte injury are incompletely understood. We (10, 11) and others (12, 13) have highlighted the importance of podocyte insulin responses in maintaining glomerular function, and it is now evident that circulating factors associated with common systemic disorders, including diabetes, obesity, and the metabolic syndrome, can directly induce podocyte insulin resistance (14⇓⇓–17) and associated damage (15, 18). In this study, we analyzed the transcriptomes of insulin-sensitive and insulin-resistant podocytes with the aim of identifying molecules that are differentially regulated in podocyte damage, which may play a role in albuminuric kidney disease. This unbiased transcriptome analysis revealed that Neuropeptide Y (Npy) was the most highly down-regulated transcript in insulin-resistant vs. insulin-sensitive podocytes. Analysis of patient cohorts also revealed a significant reduction in glomerular NPY expression in both early and late-stage diabetic nephropathy (DN), as well as in several other human albuminuric conditions. This contrasts with the increased plasma and urinary levels of NPY that are observed in diabetes and CKD (19⇓⇓–22). This prompted us to further investigate the potential role of NPY (and NPY signaling) in the podocyte and glomerulus

Rethinking use-wear analysis and experimentation as applied to the study of past hominin tool use

In prehistoric human populations, technologies played a fundamental role in the acquisition of different resources and are represented in the main daily living activities, such as with bone, wooden, and stone-tipped spears for hunting, and chipped-stone tools for butchering. Considering that paleoanthropologists and archeologists are focused on the study of different processes involved in the evolution of human behavior, investigating how hominins acted in the past through the study of evidence on archeological artifacts is crucial. Thus, investigat ing tool use is of major importance for a comprehensive understanding of all processes that characterize human choices of raw materials, techniques, and tool types. Many functional assumptions of tool use have been based on tool design and morphology according to archeologists’ interpretations and ethnographic observations. Such assumptions are used as baselines when inferring human behavior and have driven an improvement in the methods and techniques employed in functional studies over the past few decades. Here, while arguing that use-wear analysis is a key discipline to assess past hominin tool use and to interpret the organization and variability of artifact types in the archeological record, we aim to review and discuss the current state-of-the-art methods, protocols, and their limitations. In doing so, our discussion focuses on three main topics: (1) the need for fundamental improvements by adopting established methods and techniques from similar research fields, (2) the need to implement and combine different levels of experimentation, and (3) the crucial need to establish standards and protocols in order to improve data quality, standard ization, repeatability, and reproducibility. By adopting this perspective, we believe that studies will increase the reliability and applicability of use-wear methods on tool function. The need for a holistic approach that combines not only use-wear traces but also tool technology, design, curation, durability, and efficiency is also debated and revised. Such a revision is a crucial step if archeologists want to build major inferences on human decision making behavior and biocultural evolution processes.info:eu-repo/semantics/publishedVersio

Persistent Place-Making in Prehistory: the Creation, Maintenance, and Transformation of an Epipalaeolithic Landscape

Most archaeological projects today integrate, at least to some degree, how past people engaged with their surroundings, including both how they strategized resource use, organized technological production, or scheduled movements within a physical environment, as well as how they constructed cosmologies around or created symbolic connections to places in the landscape. However, there are a multitude of ways in which archaeologists approach the creation, maintenance, and transformation of human-landscape interrelationships. This paper explores some of these approaches for reconstructing the Epipalaeolithic (ca. 23,000–11,500 years BP) landscape of Southwest Asia, using macro- and microscale geoarchaeological approaches to examine how everyday practices leave traces of human-landscape interactions in northern and eastern Jordan. The case studies presented here demonstrate that these Epipalaeolithic groups engaged in complex and far-reaching social landscapes. Examination of the Early and Middle Epipalaeolithic (EP) highlights that the notion of “Neolithization” is somewhat misleading as many of the features we use to define this transition were already well-established patterns of behavior by the Neolithic. Instead, these features and practices were enacted within a hunter-gatherer world and worldview
