The temporal binding deficit hypothesis of autism
Frith has argued that people with autism show âweak central coherence,â an unusual bias toward piecemeal rather than configurational processing and a reduction in the normal tendency to process information in context. However, the precise cognitive and neurological mechanisms underlying weak central coherence are still unknown. We propose the hypothesis that the features of autism associated with weak central coherence result from a reduction in the integration of specialized local neural networks in the brain caused by a deficit in temporal binding. The visuoperceptual anomalies associated with weak central coherence may be attributed to a reduction in synchronization of high-frequency gamma activity between local networks processing local features. The failure to utilize context in language processing in autism can be explained in similar terms. Temporal binding deficits could also contribute to executive dysfunction in autism and to some of the deficits in socialization and communication
Entire functions with Julia sets of positive measure
Let f be a transcendental entire function for which the set of critical and
asymptotic values is bounded. The Denjoy-Carleman-Ahlfors theorem implies that
if the set of all z for which |f(z)|>R has N components for some R>0, then the
order of f is at least N/2. More precisely, we have log log M(r,f) > (N/2) log
r - O(1), where M(r,f) denotes the maximum modulus of f. We show that if f does
not grow much faster than this, then the escaping set and the Julia set of f
have positive Lebesgue measure. However, as soon as the order of f exceeds N/2,
this need not be true. The proof requires a sharpened form of an estimate of
Tsuji related to the Denjoy-Carleman-Ahlfors theorem.Comment: 17 page
Loneliness among under-represented older adults in the UK: a study of minority ethnic and LGBTQ+ populations
Issue Section: Late Breaking Poster Session IIIInternationally loneliness has been identified as a major public health problem. Although there is a substantial body of research about loneliness in older adults in the UK, there is a significant evidence gap reporting experiences of loneliness of older people from ethnic minorities and those who identify as lesbian, gay, or bisexual and transgender (LGBT). These two groups, under-represented in UK gerontological research, are included in our recently funded project, Socially Inclusive Ageing across the Lifecourse. In this poster we explicitly focus upon the experiences of loneliness for older adults, aged 50+, from the LGBTQ+ and minority ethnic communities. Using wave 9 data from the UK Household Longitudinal Study (UKHLS/Understanding Society) we measured loneliness using the three-item UCLA scale with a score of 6+ out of 9 defining loneliness. Of our total sample of 16,805 who completed the loneliness measure, 1.5% of respondents identified as LGB and 5.4% as Asian, 2.9% as black and 1.5% as other or mixed ethnicity. Overall, 21.7% of the population aged 50+ were lonely. Participants from a black, Asian or other ethnic minority reported higher loneliness than white respondents: 25.8%, 29.6%, 31.0% and 21.0% respectively. Respondents identifying as gay or lesbian (29.1%) or as bisexual (35.2%) reported greater loneliness in comparison to those who identified as heterosexual (21.3%). Our study is novel and timely in demonstrating the higher prevalence of loneliness in two under-represented groups of older adults with the potential consequences this may have for their health and wellbeing in later life

Social health in people with dementia and their carers. Preliminary findings from the IDEAL program
Issue Section: SESSION 4070 (SYMPOSIUM)WHO defines health as a state of complete physical, mental, and social wellbeing. There is an extensive literature examining physical and mental health in later life and, typically, measures of healthy ageing focus upon physical and/or mental health. In the IDEAL dementia research programme we investigated social health outcomes because of their importance in understanding the experience of âliving wellâ for people with dementia. Using data from the IDEAL cohort study, we examined the prevalence and predictors of social isolation in 1,052 people with mild-to-moderate dementia and 928 caregivers who were followed up at 12 and 24 months. Social isolation was assessed using the six-item Lubben Social Network Scale where a score of less than 12 suggests participants are at risk of social isolation. Linear mixed models showed that both people with dementia and caregivers experienced increased social isolation across the two-year period. At baseline 29% of people with dementia were categorised as being socially isolated compared with 14% of caregivers. For both people with dementia and caregivers, loneliness and depression were associated with greater social isolation whilst increased cultural engagement mitigated the impact of social isolation. For people with dementia cognition, the number of green and blue spaces nearby and higher trust in the local community were also important factors. Interventions aimed at increasing cultural engagement and interaction with blue and green spaces may go some way to reducing social isolation
Encountering Heritage In Ipplepen, Denbury and Torbryan
Heritage Trail produced as part of the Understanding Landscapes projectThis is one of five publications produced as part of the National Lottery Heritage Fund project "Understanding Landscapesâ. The other publications are available in ORE via the links in this record.âHistory is all around usâ may sound like a clichĂŠ, but
it is true! The buildings, settlements, roads and fields
that form the backdrop of our daily lives are all in one
sense âmodernâ â they are in use today â but they all
have a history, and that history in many cases goes
back hundreds or thousands of years.
This history manifests itself in many different ways. In some
cases buildings in use today are centuries old â notably our parish
churches, while elsewhere ancient settlements and field systems
that have gone out of use still have remains that are still visible
today. Similarly, sometimes there may be nothing visible now
of a place that was significant in the past, but its existence is
commemorated in a modern field- or place-name.
This guide aims to introduce people living in, or visiting, the
Ipplepen area to some of its history, to visit and walk in these
historic places. Locations have been chosen that can be visited
individually by car, or by foot along public rights of way, and
include both obviously historically important places but others
that people may walk past quite oblivious to whatâs there.National Lottery Heritage FundDevon County CouncilTeignbridge District CouncilBritish MuseumAssociation for Roman ArchaeologyRoman Research TrustProfessor Mick Asto
The iterated minimum modulus and conjectures of Baker and Eremenko
In transcendental dynamics significant progress has been made by studying points whose iterates escape to infinity at least as fast as iterates of the maximum modulus. Here we take the novel approach of studying points whose iterates escape at least as fast as iterates of the minimum modulus, and obtain new results related to Eremenko's conjecture and Baker's conjecture, and the rate of escape in Baker domains. To do this we prove a result of wider interest concerning the existence of points that escape to infinity under the iteration of a positive continuous function
Data Quality Over Quantity: Pitfalls and Guidelines for Process Analytics
A significant portion of the effort involved in advanced process control,
process analytics, and machine learning involves acquiring and preparing data.
Literature often emphasizes increasingly complex modelling techniques with
incremental performance improvements. However, when industrial case studies are
published they often lack important details on data acquisition and
preparation. Although data pre-processing is unfairly maligned as trivial and
technically uninteresting, in practice it has an out-sized influence on the
success of real-world artificial intelligence applications. This work describes
best practices for acquiring and preparing operating data to pursue data-driven
modelling and control opportunities in industrial processes. We present
practical considerations for pre-processing industrial time series data to
inform the efficient development of reliable soft sensors that provide valuable
process insights.Comment: This work has been accepted to the 22nd IFAC World Congress 202
Escape rate and Hausdorff measure for entire functions
The escaping set of an entire function is the set of points that tend to
infinity under iteration. We consider subsets of the escaping set defined in
terms of escape rates and obtain upper and lower bounds for the Hausdorff
measure of these sets with respect to certain gauge functions.Comment: 24 pages; some errors corrected, proof of Theorem 2 shortene
How organizational cognitive neuroscience can deepen understanding of managerial decision-making:a review of the recent literature and future directions
There is growing interest in exploring the potential links between human biology and management and organization studies, which is bringing greater attention to bear on the place of mental processes in explaining human behaviour and effectiveness. The authors define this new field as organizational cognitive neuroscience (OCN), which is in the exploratory phase of its emergence and diffusion. It is clear that there are methodological debates and issues associated with OCN research, and the aim of this paper is to illuminate these concerns, and provide a roadmap for rigorous and relevant future work in the area. To this end, the current reach of OCN is investigated by the systematic review methodology, revealing three clusters of activity, covering the fields of economics, marketing and organizational behaviour. Among these clusters, organizational behaviour seems to be an outlier, owing to its far greater variety of empirical work, which the authors argue is largely a result of the plurality of research methods that have taken root within this field. Nevertheless, all three clusters contribute to a greater understanding of the biological mechanisms that mediate choice and decision-making. The paper concludes that OCN research has already provided important insights regarding the boundaries surrounding human freedom to act in various domains and, in turn, self-determination to influence the workplace. However, there is much to be done, and emerging research of significant interest is highlighted
