The changing patterns of group politics in Britain
Two interpretations of ways in which group politics in Britain have presented challenges to democracy are reviewed: neo-corporatism or pluralistic stagnation and the rise of single issue interest groups. The disappearance of the first paradigm created a political space for the second to emerge. A three-phase model of group activity is developed: a phase centred around production interests, followed by the development of broadly based 'other regarding' groups, succeeded by fragmented, inner directed groups focusing on particular interests. Explanations of the decay of corporatism are reviewed. Single issue group activity has increased as party membership has declined and is facilitated by changes in traditional media and the development of the internet. Such groups can overload the policy-making process and frustrate depoliticisation. Debates about the constitution and governance have largely ignored these issues and there is need for a debate
Evidence of strong small-scale population structure in the Antarctic freshwater copepod Boeckella poppei in lakes on Signy Island, South Orkney Islands
Environmental conditions were particularly severe during the Last Glacial Maximum, altering the distribution of the Southern Hemisphere biota, particularly at higher latitudes. The copepod Boeckella poppei is the only macroscopic continental invertebrate species known to be distributed today across the three main biogeographic regions in Antarctica as well as in southern South America. Signy Island (South Orkney Islands) is a unique location for the study of Antarctic freshwater ecosystems due to its location and geographic isolation; it contains 17 lakes in several low altitude catchments. We conducted phylogeographic and demographic analyses using the cox1 gene on 84 individuals of B. poppei from seven lakes across Signy Island. We recorded low levels of genetic diversity and a strong genetic differentiation signal between the eastern and western valleys within the island. Phylogeographic structure and demographic inference analyses suggested at least one asymmetrical dispersal event from west to east. Demographic inference detected a strong signal of population growth during the deglaciation process, which may have followed either (1) a strong genetic bottleneck due to a reduction in population size during the last glacial period, or (2) a founder effect associated with postglacial recolonization of Signy Island from elsewhere. The genetic architecture of this island's populations of B. poppei shows that historical events, rather than continuous dispersal events, likely played a major role in the species' current distribution. Finally, our study considers possible mechanisms for dispersal and colonization success of the most dominant species in the Antarctic freshwater community
'We stand in the Luddite legacy': Tracking Patterns of Anti-GM Crop-Trashing in the United Kingdom
Concern over the uncertainty associated with genetically modified (GM) products from the late 1990s in the UK led to an extensive anti-GM campaign. Activists adopted a broad array of tactics from conventional protest marches and rallies through to more unconventional and confrontational actions. An important part of the protest repertoire was the physical damage and destruction of GM crops. These were intensified following the decision of the government to license a series of field scale evaluations (FSE) of GM crops intended to determine their potential impact on biodiversity. The aim of the article is to determine why crop-trashing such a significant tactic. The paper draws on a protest event catalogue of anti-GM protests over the 1996-2016 period to identify their intensity, tactics and locations. The findings suggest that crop-trashing was primarily adopted due to the availability of targets. However, it also points to the rural setting as a space in which different norms and histories provide a justification for destructive acts in the face of uncertainty
Methodological considerations for the special-risk researcher: a research note
Researchers seeking to investigate the dynamics and individuals constituting todayâs myriad social movements must grapple with attendant challenges such as designing a methodological framework appropriate for investigating subjects and phenomena of interest, as well as gaining and maintaining access to groups of interest. Such challenges are magnified many times over when the groups under investigation pose potential special safety risks to themselves as well as researchers through engagement in dangerous or illegal activities, problematize previously conceived research criteria for suitable participants due to their amorphous and transient organizational dynamics or are otherwise difficult to access. In this research note, I recount my experiences in the field and the various methodological readjustments I was compelled to make as a result while conducting qualitative investigations of radical environmental activists for my PhD thesis. It is hoped that the experiences and insights gleaned from the research note will be deemed of value for future scholars engaging in 'special-risk' research
From âgreenest government everâ to âget rid of all the green crapâ: David Cameron, the Conservatives and the environment
The environment was David Cameronâs signature issue underpinning his modernization agenda. In opposition the âVote Blue, Go Greenâ strategy had a positive impact on the partyâs image: the environment operated as a valence issue in a period of raised public concern, particularly about climate change, and Cameronâs high-profile support contributed to the cross-party consensus that delivered radical change in climate policy. Although the Coalition government has implemented important environmental measures, the Conservatives have not enhanced their green credentials in government and Cameron has failed to provide strong leadership on the issue. Since 2010, climate change has to some extent been transformed into a positional issue. Conservative MPs, urged on by the right-wing press, have adopted an increasingly partisan approach to climate change, and opinion polls reveal clear partisan divisions on climate change amongst public opinion. As a positional issue climate change has become challenging for the Conservatives, showing them to be internally divided, rebellious and inclined to support producer interests. This article makes a contribution to our understanding of Conservative modernization, while also challenging the dominant assumption in the scholarly literature that the environment, particularly climate change, is a valence issue
Millbank tendency: the strengths and limitations of mediated protest âeventsâ in UK student activism cycles
UK studentsâ desire to create disruptive, media-friendly âeventsâ during the 2010-11 protests against fees and cuts is reflective of wider cycles and processes in student activism history. First, constant cohort turnover restricts studentsâ ability to convert campaigns into durable movements, necessitating that they must periodically âstart from scratchâ. This informs a second process, namely the need to gain the attention of mainstream media, as this can potentially amplify studentsâ grievances far beyond their own organisational capacities. Both have shaped student activism over the past fifty years, compelling contemporary students to create protest events that live up to their radical history. These processes were evident in autumn 2010, when an NUS demonstration saw students attack and briefly occupy Conservative Party headquarters at 30 Millbank. The protestâs mass mediation was central to activistsâ âeventingâ processes, and provided the spark for the radical UK-wide campaign that followed. Yet once the fees bill was passed by Parliament, studentsâ dependency on mainstream media cycles was quickly exposed. With âmediatizationâ tendencies having dogged student activism since the sixties, this article argues that creating âeventsâ epitomises studentsâ longstanding strengths and limitations as societyâs âincipient intelligentsiaâ (Rootes, 1980: 475)
Differences in the neural correlates of schizophrenia with positive and negative formal thought disorder in patients with schizophrenia in the ENIGMA dataset
Formal thought disorder (FTD) is a clinical key factor in schizophrenia, but the neurobiological underpinnings remain unclear. In particular, the relationship between FTD symptom dimensions and patterns of regional brain volume loss in schizophrenia remains to be established in large cohorts. Even less is known about the cellular basis of FTD. Our study addresses these major obstacles by enrolling a large multi-site cohort acquired by the ENIGMA Schizophrenia Working Group (752 schizophrenia patients and 1256 controls), to unravel the neuroanatomy of FTD in schizophrenia and using virtual histology tools on implicated brain regions to investigate the cellular basis. Based on the findings of previous clinical and neuroimaging studies, we decided to separately explore positive, negative and total formal thought disorder. We used virtual histology tools to relate brain structural changes associated with FTD to cellular distributions in cortical regions. We identified distinct neural networks positive and negative FTD. Both networks encompassed fronto-occipito-amygdalar brain regions, but positive and negative FTD demonstrated a dissociation: negative FTD showed a relative sparing of orbitofrontal cortical thickness, while positive FTD also affected lateral temporal cortices. Virtual histology identified distinct transcriptomic fingerprints associated for both symptom dimensions. Negative FTD was linked to neuronal and astrocyte fingerprints, while positive FTD also showed associations with microglial cell types. These results provide an important step towards linking FTD to brain structural changes and their cellular underpinnings, providing an avenue for a better mechanistic understanding of this syndrome
Mutual aid groups in psychiatry and substance misuse
Background: Mutuality is a feature of many âself-help groupsâ for people with mental health and/or substance misuse needs. These groups are diverse in terms of membership, aims, organisation and resources. Collectively, in terms of the pathways for seeking help, support, social capital or simply validation as people, mutual aid groups figure at some time in the life story of many psychiatric and/or substance misuse patients. From the viewpoint of clinical services, relations with such groups range from formal collaboration, through incidental shared care, via indifference, to incomprehension, suspicion, or even hostility. How should mental health and substance misuse clinicians relate to this informal care sector, in practice?
Aims: To synthesise knowledge about three aspects of the relationship between psychiatric/substance misuse services and mutual aid groups:
profile groups' engagement of people with mental health and/or substance misuse needs at all stages of vulnerability, illness or recovery;
characterise patterns of health benefit or harm to patients, where such outcome evidence exists;
identify features of mutual aid groups that distinguish them from clinical services.
Method: A search of both published and unpublished literature with a focus on reports of psychiatric and substance misuse referral routes and outcomes, compiled for meta-synthesis.
Results: Negative outcomes were found occasionally, but in general mutual aid group membership was repeatedly associated with positive benefits.
Conclusions: Greater awareness of this resource for mental health and substance misuse fields could enhance practice
