Keeping on[line] farming: Examining young farmers’ digital curation of identities, (dis)connection and strategies for self-care through social media

File replaced (docx to pdf) on 27.4.23 by NK (LDS)This paper explores the geographies of digital curation and self-care among young farmers in the UK, examining how virtual and digital spaces are having a significant impact on how young farmers negotiate their identities, (dis)connection and self-care within their everyday lives. Drawing on interviews with 28 young famers in the UK, we observe how farming identities are (re)produced and practiced online, via carefully curated social media, and how these might constitute practices of self-care in overcoming issues such as disconnection and rural isolation. Our analysis reveals how social media posts are more than simple connections, they are curations of the self that are complexly bound up in the emotional, spatial and temporal contexts of the author’s identities. We examine how digital curation is not just an act of the self, but something drawn relationally to others. Attention is given not just to what is posted, but how others are (dis)engaged with, and how posts of others are reacted to, or endorsed, implicitly or explicitly. Through our examination of young farmers’ social identities, we therefore argue that digital identities are produced, practiced, managed and understood in very specific ways ‘online’, in ways that carefully overlap with other geographical identities

Analysis of Per Capita Contributions from a Spatial Model Provides Strategies for Controlling Spread of Invasive Carp

Metapopulation models may be applied to inform natural resource management to guide actions targeted at location-specific subpopulations. Model insights frequently help to understand which subpopulations to target and highlight the importance of connections among subpopulations. For example, managers often treat aquatic invasive species populations as discrete populations due to hydrological (e.g., lakes, pools formed by dams) or jurisdictional boundaries (e.g., river segments by country or jurisdictional units such as states or provinces). However, aquatic invasive species often have high rates of dispersion and migration among heterogenous locations, which complicates traditional metapopulation models and may not conform to management boundaries. Controlling invasive species requires consideration of spatial dynamics because local management activities (e.g., harvest, movement deterrents) may have important impacts on connected subpopulations. We expand upon previous work to create a spatial linear matrix model for an aquatic invasive species, Bighead Carp, in the Illinois River, USA, to examine the per capita contributions of specific subpopulations and impacts of different management scenarios on these subpopulations. Managers currently seek to prevent Bighead Carp from invading the Great Lakes via a connection between the Illinois Waterway and Lake Michigan by allocating management actions across a series of river pools. We applied the model to highlight how spatial variation in movement rates and recruitment can affect decisions about where management activities might occur. We found that where the model suggested management actions should occur depend crucially on the specific management goal (i.e., limiting the growth rate of the metapopulation vs. limiting the growth rate of the invasion front) and the per capita recruitment rate in downstream pools. Our findings illustrate the importance of linking metapopulation dynamics to management goals for invasive species control

2009,02: Evolutionary Policy

We explore the idea of public policy from the perspective of evolutionary thinking. This involves paying attention to concepts like diversity, population, selection, innovation, coevolution, group selection, path-dependence and lock-in. We critically discuss the notion of evolutionary progress. The relevance of evolutionary dynamics is illustrated for policy and political change, technical change, sustainability transitions and regulation of consumer behaviour. A lack of attention for the development of evolutionary policy criteria and goals is identified and alternative choices are critically evaluated. Finally, evolutionary policy advice is compared with policy advice coming from neoclassical economics, public choice theory and theories of resilience and adaptive management. We argue that evolutionary thinking offers a distinct and useful perspective on public policy design and change. -- Adaptive management ; coevolution ; escaping lock-in ; evolutionary politics ; evolutionary progress ; innovation policy ; optimal diversity ; resilience ; social-technical transitio

Assessing the conservation value of waterbodies: the example of the Loire floodplain (France)

In recent decades, two of the main management tools used to stem biodiversity erosion have been biodiversity monitoring and the conservation of natural areas. However, socio-economic pressure means that it is not usually possible to preserve the entire landscape, and so the rational prioritisation of sites has become a crucial issue. In this context, and because floodplains are one of the most threatened ecosystems, we propose a statistical strategy for evaluating conservation value, and used it to prioritise 46 waterbodies in the Loire floodplain (France). We began by determining a synthetic conservation index of fish communities (Q) for each waterbody. This synthetic index includes a conservation status index, an origin index, a rarity index and a richness index. We divided the waterbodies into 6 clusters with distinct structures of the basic indices. One of these clusters, with high Q median value, indicated that 4 waterbodies are important for fish biodiversity conservation. Conversely, two clusters with low Q median values included 11 waterbodies where restoration is called for. The results picked out high connectivity levels and low abundance of aquatic vegetation as the two main environmental characteristics of waterbodies with high conservation value. In addition, assessing the biodiversity and conservation value of territories using our multi-index approach plus an a posteriori hierarchical classification methodology reveals two major interests: (i) a possible geographical extension and (ii) a multi-taxa adaptation

Fatal gunshot trauma of a child: A case from colonial Cyprus

Forensic science has made some significant contributions to the investigation of human rights abuses related to armed conflicts, especially in the last 40 years. Some investigations are aimed at the collection of evidence in order to prosecute those responsible, while others are humanitarian in nature. This paper presents the multidisciplinary effort to recover and identify the remains of a 7-year-old child who was shot by British colonial forces in Cyprus in 1956. An investigation led to the discovery of the burial site, and archaeological methods were used to recover the remains. The anthropological examination provided information about the age of the child, as well as the nature of the skeletal trauma present. DNA results confirmed the identity of the victim, and the remains were released to the surviving family members for burial

Public Versus Private: Does It Matter for Water Conservation? Insights from California

This article asks three connected questions: First, does the public view private and public utilities differently, and if so, does this affect attitudes to conservation? Second, do public and private utilities differ in their approaches to conservation? Finally, do differences in the approaches of the utilities, if any, relate to differences in public attitudes? We survey public attitudes in California toward (hypothetical but plausible) voluntary and mandated water conservation, as well as to price increases, during a recent period of shortage. We do this by interviewing households in three pairs of adjacent public and private utilities. We also survey managers of public and private urban water utilities to see if they differ in their approaches to conservation and to their customers. On the user side we do not find pronounced differences, though a minority of customers in all private companies would be more willing to conserve or pay higher prices under a public operator. No respondent in public utility said the reverse. Negative attitudes toward private operators were most pronounced in the pair marked by a controversial recent privatization and a price hike. Nonetheless, we find that California’s history of recurrent droughts and the visible role of the state in water supply and drought management undermine the distinction between public and private. Private utilities themselves work to underplay the distinction by stressing the collective ownership of the water source and the collective value of conservation. Overall, California’s public utilities appear more proactive and target-oriented in asking their customers to conserve than their private counterparts and the state continues to be important in legitimating and guiding conservation behavior, whether the utility is in public hands or private

Hepatic wound repair

BACKGROUND: Human chronic liver diseases (CLDs) with different aetiologies rely on chronic activation of wound healing that represents the driving force for fibrogenesis progression (throughout defined patterns of fibrosis) to the end stage of cirrhosis and liver failure. ISSUES: Fibrogenesis progression has a major worldwide clinical impact due to the high number of patients affected by CLDs, increasing mortality rate, incidence of hepatocellular carcinoma and shortage of organ donors for liver transplantation. BASIC SCIENCE ADVANCES: Liver fibrogenesis is sustained by a heterogeneous population of profibrogenic hepatic myofibroblasts (MFs), the majority being positive for alpha smooth muscle actin (alphaSMA), that may originate from hepatic stellate cells and portal fibroblasts following a process of activation or from bone marrow-derived cells recruited to damaged liver and, in a method still disputed, by a process of epithelial to mesenchymal transition (EMT) involving cholangiocytes and hepatocytes. Recent experimental and clinical data have identified, at tissue, cellular and molecular level major profibrogenic mechanisms: (a) chronic activation of the wound-healing reaction, (b) oxidative stress and related reactive intermediates, and (c) derangement of epithelial-mesenchymal interactions. CLINICAL CARE RELEVANCE: Liver fibrosis may regress following specific therapeutic interventions able to downstage or, at least, stabilise fibrosis. In cirrhotic patients, this would lead to a reduction of portal hypertension and of the consequent clinical complications and to an overall improvement of liver function, thus extending the complication-free patient survival time and reducing the need for liver transplantation. CONCLUSION: Emerging mechanisms and concepts related to liver fibrogenesis may significantly contribute to clinical management of patients affected by CLDs
