A spatial judgement task to determine background emotional state in laboratory rats (Rattus norvegicus)
Humans experiencing different background emotional states display contrasting cognitive (e.g. judgement) biases when responding to ambiguous stimuli. We have proposed that such biases may be used as indicators of animal emotional state. Here, we use a spatial judgement task, in which animals are trained to expect food in one location and not another, to determine whether rats in relatively positive or negative emotional states respond differently to ambiguous stimuli of intermediate spatial location. We housed 24 rats with environmental enrichment for seven weeks. Enrichment was removed for half the animals prior to the start of training (‘U’: unenriched) to induce a relatively negative emotional state, whilst being left in place for the remaining rats (‘E’: enriched). After six training days, the rats successfully discriminated between the rewarded and unrewarded locations in terms of an increased latency to arrive at the unrewarded location, with no housing treatment difference. The subjects then received three days of testing in which three ambiguous ‘probe’ locations, intermediate between the rewarded and unrewarded locations, were introduced. There was no difference between the treatments in the rats’ judgement of two out of the three probe locations, the exception being when the ambiguous probe was positioned closest to the unrewarded location. This result suggests that rats housed without enrichment, and in an assumed relatively negative emotional state, respond differently to an ambiguous stimulus compared to rats housed with enrichment, providing evidence that cognitive biases may be used to assess animal emotional state in a spatial judgement task
Genes in the postgenomic era
We outline three very different concepts of the gene - 'instrumental', 'nominal', and 'postgenomic'. The instrumental gene has a critical role in the construction and interpretation of experiments in which the relationship between genotype and phenotype is explored via hybridization between organisms or directly between nucleic acid molecules. It also plays an important theoretical role in the foundations of disciplines such as quantitative genetics and population genetics. The nominal gene is a critical practical tool, allowing stable communication between bioscientists in a wide range of fields grounded in well-defined sequences of nucleotides, but this concept does not embody major theoretical insights into genome structure or function. The post-genomic gene embodies the continuing project of understanding how genome structure supports genome function, but with a deflationary picture of the gene as a structural unit. This final concept of the gene poses a significant challenge to conventional assumptions about the relationship between genome structure and function, and between genotype and phenotype
Medicalisation of Vaping in the UK? E-cigarette users’ perspectives on the merging of commercial and medical routes to vaping
Background: In the UK, most smokers choosing e-cigarettes to quit smoking will access vaping via commercial routes. In recent years, however, a shift towards medicalisation of vaping has become apparent, with public health guidance supporting e-cigarettes for smoking cessation and increased partnership working between healthcare professionals and the vaping industry. To achieve the UK’s Smokefree 2030 target, the UK Government has set out measures to utilise e-cigarettes in NHS settings and to move towards streamlining processes to make e-cigarettes available to a million smokers. This paper aims to understand acceptability of different approaches by seeking perspectives of people with lived experience of e-cigarette use for smoking cessation. Methods: Mixed methods data, collected between March 2018 and March 2019 as part of a broader study of e-cigarette use trajectories (ECtra study). Data here relate to views of partnership working and medicalisation of vaping extracted from 136 interviews/extended surveys of people who had used e-cigarettes to try to stop smoking. Qualitative data were thematically analysed. Participant ratings of interventions were presented descriptively and differences in participant characteristics and ratings were reported. Results: Three qualitative themes were identified: pro-partnership, anti-partnership and medicalisation dissonance. Medicalisation was discussed for its potential to reassure smokers about e-cigarette harms and its potential to reach smokers from disadvantaged backgrounds. Concerns were raised about cost effectiveness, quality of support, conflicts of interest, and limiting product choice. Most participants rated interventions involving partnership working as potentially helpful in switching from smoking to vaping. There were no statistically significant associations between age, gender and socio-economic status and helpfulness ratings. Conclusions: Both commercial and medical routes to vaping offer perceived benefits to vapers and may complement and reinforce each other to support smoking cessation
The development and evaluation of a mentor training programme for those working with autistic adults
This paper evaluates the training developed for potential mentors wanting to work with autistic adults to enable them to work towards their chosen goals. It then gives some initial findings of how the mentoring worked in practice. Research Autism provided the funding to offer a one day training event free to adults who expressed a wish to work as a mentor. Fifty people were trained and 45 of these completed a feedback form. This provided excellent information on the content and delivery. The most highly rated aspect of the training was the fact the much of the content was developed and delivered by autistic adults. The most often cited way to enhance the training would to extend this to two days as a great deal was packed into the day. Not all those who attended the training went on to act as mentors but it was felt they would have gained from receiving the training. It was felt that short-term, goal oriented mentoring was likely to be the most effective. There is little data presented on the goals the mentors worked on and with what degree of success as that is the subject of future papers. Instead the focus was on the training offered. It came to light that some of the mentors who did start to work with autistic adults were not reliable and so future training will stress the importance of this. A key point throughout the paper is the need to involve autistic individuals in training and interventions designed for autistic people. Such work is slowly developing and becoming more common and this paper adds to the literature on this
Fairer decisions, better health for all : Health equity and cost-effectiveness analysis
This report provides a non-technical introduction to practical methods for using cost-effectiveness analysis to address health equity concerns, with applications to low-, middle- and high-income countries. These methods can provide information about the likely impacts of alternative health policy decisions on inequalities in health, financial risk protection and other health-related outcomes that may be considered unfair, allowing for the distribution of costs as well as benefits. They can also provide information about the trade-offs that sometimes arise between improving total health and reducing health inequalities of different kinds. We distinguish three general ways of using cost-effectiveness analysis to address health equity concerns: (1) equity impact analysis, which quantifies the distribution of costs and effects across a population by equity-relevant variables such as socioeconomic status, ethnicity, location, gender, age and severity of illness; (2) equity constraint analysis, which counts the cost of choosing fairer but less cost-effective options; and (3) equity weighting analysis, which uses equity weights or parameters to explore how much concern for equity is required to choose fairer but less cost-effective options. We hope this report will raise awareness of the practical tools of cost-effectiveness analysis that are now available to help give health care and public health policy makers a better understanding of who gains and who loses from their priority setting decisions
Thinking like a man? The cultures of science
Culture includes science and science includes culture, but conflicts between the two traditions persist, often seen as clashes between interpretation and knowledge. One way of highlighting this false polarity has been to explore the gendered symbolism of science. Feminism has contributed to science studies and the critical interrogation of knowledge, aware that practical knowledge and scientific understanding have never been synonymous. Persisting notions of an underlying unity to scientific endeavour have often impeded rather than fostered the useful application of knowledge. This has been particularly evident in the recent rise of molecular biology, with its delusory dream of the total conquest of disease. It is equally prominent in evolutionary psychology, with its renewed attempts to depict the fundamental basis of sex differences. Wars over science have continued to intensify over the last decade, even as our knowledge of the political, economic and ideological significance of science funding and research has become ever more apparent
Why Did Memetics Fail? Comparative Case Study
Although the theory of memetics appeared highly promising at the beginning, it is no longer considered a scientific theory among contemporary evolutionary scholars. This study aims to compare the genealogy of memetics with the historically more successful gene-culture coevolution theory. This comparison is made in order to determine the constraints that emerged during the internal development of the memetics theory that could bias memeticists to work on the ontology of meme units as opposed to hypotheses testing, which was adopted by the gene-culture scholars. I trace this problem back to the diachronic development of memetics to its origin in the gene-centered anti-group-selectionist argument of George C. Williams and Richard Dawkins. The strict adoption of this argument predisposed memeticists with the a priori idea that there is no evolution without discrete units of selection, which in turn, made them dependent on the principal separation of biological and memetic fitness. This separation thus prevented memeticists from accepting an adaptationist view of culture which, on the contrary, allowed gene-culture theorists to attract more scientists to test the hypotheses, creating the historical success of the gene-culture coevolution theory
Does ‘mentoring’ offer effective support to autistic adults?: a mixed methods pilot study
The Research Autism Cygnet Mentoring project was a two-year pilot study, completed in 2016, which aimed to develop, trial and evaluate a mentoring scheme designed with input from autistic people, their families and supporters. The mentoring scheme involved 12 matched pairs (mentor/mentee) meeting once per week for one hour, over a six month period. All mentors attended a training day, led by the principles of Personal Construct Theory (PCT) and an emancipatory research ethos. The project and training involved significant involvement of autistic people in both its design and delivery. Participants on the autism spectrum found their mentoring experience very helpful in enabling them to progress toward self-identified goals, and mentees felt empowered by the person-centred ethos and methods employed on the project. However, a number of aspects of the mentoring project have been identified for requiring further investigation, including: caution over offering mentoring without formal structures, boundary setting, supervision, flexibility, and the matching of mentees with mentors. The project has highlighted the potential benefits of time-limited goal-orientated mentoring and the negligible evidence base underpinning current mentoring practice with adults on the autism spectrum. In order for the project to realise its emancipatory aim, there is a need for a large-scale quantitative study and a health-economics analysis to provide the necessary evidence base for mentoring to be recommended as a cost-effective intervention with clear benefits for individual wellbeing
