Comparing aversive and appetitive learning performances in individual honeybees

Background A neurobiological perspective has become accepted as a valuable approach for understanding anti-social behaviour. There is literature to suggest that, in non-offending populations, psychological treatments affect both neurobiological measures and clinical presentation. A theoretical position to this effect has been adopted with respect to offender treatment, but there has been no systematic review of empirical literature on this point. Aims This study aimed to ascertain from published literature firstly whether there is evidence of change in neuropsychological or physiological measures after behavioural treatments/programmes for people with anti-social behaviour and secondly whether these neurobiological changes are associated with behavioural change. Method A systematic search strategy was formulated to include studies considering neurobiological factors', anti-social population', treatment' and treatment outcome'. The Maryland Scientific Methods Scale was used to select relevant studies of sufficient methodological quality. Results Eleven studies were found, only one with adults. Overall, the values of specific neurobiological risk factors, particularly of basal cortisol, become less abnormal following intervention. There was some evidence for a link between change in neurobiological functioning and behavioural improvement. Conclusions Findings, although provisional, may provide new insights into the underlying mechanisms of interventions for anti-social behaviour. Future studies that include pre-treatment neurobiological assessment could help reveal physical vulnerabilities that interventions should target to improve treatment efficacy, and provide for objective, independent corroboration of change

Toxocara vitulorum & Fasciola gigantica in cattle and buffalo in northern Laos

LUZIA RAST – PhD THESIS… abstract Toxocara vitulorum & Fasciola gigantica in Cattle and Buffalo in Northern Laos In South-East Asia agricultural production including livestock is predominately produced within mixed smallholder farming systems. These mostly operate at subsistence levels. Cattle and buffalo are typically kept as assets rather than for optimal production purposes. Economic growth and urbanisation in the region continues to lead to increased demand for red meat products. This provides opportunities and pressures for smallholder farmers to increase their livestock outputs and supply this market with consistent and high quality products. Laos is well placed to supply this increasing regional demand but constraints inhibiting optimal production outputs from smallholder farming systems need to be addressed. These constraints include low capacity animal health systems, lack of infrastructure, traditional low input/low output farming methods and endemic livestock diseases. There is limited documentation about disease prevalence in large ruminants and basic production benchmarks such as reproductive, morbidity and mortality rates. Anecdotal reports indicate that Fasciola gigantica and Toxocara vitulorum are endemic in Laos and contribute to substantial production losses. This is despite the availability of relative cheap and simple treatment technology for T.vitulorum and substantial past research investment in the region on both parasites. The research presented in this thesis contributes to knowledge on the prevalence of T.vitulorum and F.gigantica in cattle and buffalo and the impact of these parasitic infections on production in mixed smallholder farming systems in northern Laos, which are typical for many other parts of South-East Asia. It further contributes to defining and documenting basic large ruminant production parameters within these production systems and quantifies the financial impact of T.vitulorum treatment of calves. Importantly this research identified a large gap in knowledge and in the sustained adoption of effective control practices for large ruminant internal parasites and explored pathways and gives recommendations to address this. The thesis presents data from seven separate field studies completed in northern Laos between 2009 and 2012. Two cross-sectional field surveys were conducted and results showed that both T.vitulorum in cattle and buffalo calves and F.gigantica in adult cattle and buffalo had high apparent prevalence (22.6% and 17.2% respectively) and were geographically widespread throughout northern Laos. Results further indicated that both parasites affected cattle and buffalo at similar levels and that no specific clinical signs were associated with either parasite. This was in line with past research on F.gigantica infection but not for T.vitulorum with limited past research and anecdotal reports indicating that Toxocariasis causes diarrhoea and rough coats in calves and especially so in buffalo calves. Slaughterhouse surveys were conducted in five main provincial slaughterhouses in northern Laos. Results showed a prevalence of faecal eggs for F.gigantica (34.1%) plus liver lesions consistent with F.gigantica infection in 71.0% of slaughtered cattle and buffalo providing further evidence of the endemic nature of this parasite and its potential clinical impact across northern Laos. Additional findings of the slaughterhouse surveys were that a large proportion of slaughtered female animals were pregnant (44% cattle, 47% buffalo), 9.8% of slaughtered animals had FMD lesions and meat inspectors were rarely present for the entire slaughter process with no condemnation of any products. Two separate farmer surveys on a sample of farmers that had their large ruminants tested for either T.vitulorum or F.gigantica were conducted using face-to-face semi-structured interviews. Results of the T.vitulorum farmer survey (n=273) showed that there was a relative high rate of awareness (62.3%) about this parasite amongst farmers and that specific knowledge about its epidemiology and potential clinical impact was lacking. Only 2.5% of farmers used pyrantel treatment of calves at the recommended age and dose rate. Results of the farmer survey (n=326) for F.gigantica showed smallholders had very limited knowledge about Fasciolosis in large ruminants despite 20.6% reporting having seen leaf shaped parasites in livers of slaughtered cattle or buffalo in the past. None of the interviewed farmers treated larger ruminants to control liver fluke. Analyses of large ruminant production data found annual calf morbidity and mortality rates of 42.6% (CI 0.38-0.47) and 37.3% (CI 0.33-0.42) respectively; and adult morbidity and mortality rates of 7.4% (CI 0.06-0.09) and 2.8% (CI 0.003-0.05) respectively. Further, results showed low reproductive performance of 0.6 and 0.4 calf per year for cattle and buffalo respectively with first calving ages of 36 months reported for both species. Two separate field treatment trials were conducted. For T.vitulorum calves were treated when they were 90% reduction of faecal egg counts in adult cattle and buffalo four, eight and twelve weeks post treatment compared to untreated animals. In addition there was a trend of increased weight gain in treated buffalo compared to the untreated control group indicating that treatment of Fasciolosis may result in heavier buffalo. Financial analysis using partial budgeting and data from our surveys showed that there was a large net benefit of USD 3.69-14.86 per calf for treatment with pyrantel (12.5 mg/kg) once only between 14-21 days of age compared to no treatment. It was concluded that both T.vitulorum and F.gigantica are endemic in northern Laos and contribute to substantial production losses in this area. Smallholder farmers still keep large ruminants mostly as an asset and there is also a large knowledge gap amongst smallholder producers about internal parasites, their health and production effects and effective control methods. This knowledge gap and the lack of commercial driver contribute to the deficit of widespread adoption of parasite control methods by smallholder farmers despite their availability and known effectiveness. These results suggest, especially for T.vitulorum that if recommended control methods were widely adopted, large ruminant production output from smallholder farming systems could be increased through reduced calf morbidity and mortality rates

Interaction with the future self in virtual reality reduces self-defeating behavior in a sample of convicted offenders

In this study, we test an intervention in which convicted offenders interacted with an age-progressedavatar representing their future selves in virtual reality. During the interaction, they reflected on theircurrent lifestyle, alternating between the perspective of their present self and that of their future self.We hypothesized that this embodied experience would increase their ability to imagine themselvesin the future and reduce their engagement in self-defeating behavior, as measured with a self-reportsurvey. In line with expectations, results indicated that the interaction increased vividness of thefuture self compared to baseline and reduced self-defeating behavior, including alcohol use andoverspending, one week later. In addition, increases in vividness were associated with a reductionin self-defeating behavior over and above other concepts relating to the future self, includingconnectedness, similarity, and valence. The results are based on a small sample and should thereforebe considered as indicative of the possibilities of our virtual reality paradigm as an intervention tool toreduce self-defeating behavior.Development Psychopathology in context: clinical setting

The Extreme Male Brain theory and gender role behaviour in persons with an autism spectrum condition

According to the Extreme Male Brain theory persons with autism possess masculinised cognitive traits. In this study masculinisation of gender role behaviour is evaluated in 25 persons with an autism spectrum condition (ASC) and matched controls with gender role behaviour as part of a shortened version of the Minnesota Multiphasic Personality Inventory-2 and the Empathizing Quotient and Systemizing Quotient. Both males and females with an ASC showed minimum male role behaviour. It is suggested that the minimum male gender role could be related to an underdeveloped Theory of Mind, a well-known feature of autism. (C) 2011 Elsevier Ltd. All rights reserved

De 'zelfmetende' justitiabele

Quantifying personal characteristics with help of technological devices, such as smartwatches and smartphones, has become a common activity among people over the past years. In the field of criminal justice, there is an increasing interest in these techniques. Self-measurement equipment could potentially contribute to tailor-made treatment and supervision and could possibly 'empower' individuals. This report investigates how technological self-measurement equipment could enrich judicial processes. At the same time, potential risks related to technological self-measurement methods are highlighted. See also: Infographic The 'self-measuring' delinquent

Does a cognitive skills training program for prisoners affect neurocognitive functioning and heart rate activity?

Item does not contain fulltextThis study investigates changes in neurobiological characteristics after a cognitive skills program for prisoners. It was hypothesized that prisoners who completed a cognitive skills training program would show improved neurocognitive functioning and changes in heart rate (HR) activity. In addition, it was expected that neurobiological changes were related to behavioral improvement. Male adult prisoners were included in the study and divided into two groups: the intervention groupprisoners participating in a cognitive skills training programand the control groupprisoners placed on a waitlist. Several neurocognitive skills and HR activity measures were assessed at pre- and posttest assessment. In addition, trainers, prison officers, and prisoners were requested to evaluate behavioral changes over time. Results did not confirm the hypotheses. The absence of both neurobiological and behavioral improvement is discussed in light of the measures used, the content and duration of the current intervention program, and the prison setting.26 p
