Establishing mand emergence: The effects of three training procedures and modified antecedent conditions

This study examined the effects of a modified antecedent during probes for emergent mands following listener versus tact training for children with autism. Eight students, aged 7 to 11, were trained to respond to 3 sets of relational responses (front/back, left/right, on/under), each assigned a nonsense label. Three training types were evaluated: listener training, tact training, and listener– tact training combined. Following the experimental training, probes for emergent mands were conducted under modified antecedent conditions. Results showed that modified antecedent conditions were critical in demonstrating mand emergence for some participants

Contamination of the lairage of a pork abattoir with Salmonella species

The objectives of this study were to determine the prevalence of Salmonella spp. In the lairage of a pork abattoir on different days of the week and to investigate the effect of daily washing routines and disinfection procedures on contamination levels with Salmonella spp. In total, 359 swabs were collected from lairage pen floors at three time points during the course of two slaughter days. All samples were analysed quantitatively

Infection of pigs following exposure to contaminated pen floors

The objective of these studies was to determine if pigs could acquire infection when exposed to different levels of environmental contamination with Salmonella typhimurium. In experiment 1, pigs were euthanised after 2, 3 and 24 hours of exposure to a highly contaminated environment (105 organisms/100cm2)

Down the local: A qualitative case study of daytime drinking spaces in the London Borough of Islington.

BACKGROUND: Recognising the lack of research on daytime drinking practices in areas with managed night-time economies (NTEs), this qualitative study explores the phenomena in the London Borough of Islington; a rapidly gentrifying area with a highly regulated night-time economy (NTE). The objectives were to (i) Characterise the daytime drinking spaces of the local alcohol environment and (ii) Theorise the ways in which these spaces, and the practices and performativities within them, are situated within broader social and economic trends. METHODS: Adopting a legitimate peripheral participation approach to data collection, 39 licensed premises were visited in Islington and on-site observations carried out between the hours of 12 pm and 6 pm using a semi-structured observation guide. Observations were written-up into detailed fieldnotes, uploaded to NVivo and subject to a thematic analysis. FINDINGS: The daytime on-premises alcohol environment was characterised by two main trends: the decline of traditional pubs and a proliferation of hybrid establishments in which alcohol was framed as part of a suite of attractions. The consumption trends that the latter exemplify are implicated in processes of micro-cultural production and 'hipster capitalism'; and it is via this framing that we explore the way the diverse local drinking spaces were gendered and classed. Hybrid establishments have been regarded as positive in terms of public health, crime and safety. However, they could also help introduce drinking within times and contexts where it was not previously present. CONCLUSION: The intersection of an expanding hipster habitus with Local Authority efforts to tackle 'determined drunkenness' create very particular challenges. The operating practices of hybrid venues may feed into current alcohol industry strategies of promoting 'new moments' in which consumers can drink. They blur the divisions between work and play and produce temporal and classed divisions of drinking

A Numerical Examination of ¹⁴CO₂ Chamber Methodologies for Sampling at the Soil Surface

Radiocarbon is an exceptionally useful tool for studying soil-respired CO₂, providing information about soil carbon turnover rates, depths of production, and the biological sources of production through partitioning. Unfortunately, little work has been done to thoroughly investigate the possibility of inherent biases present in current measurement techniques, like those present in δ¹³CO₂ methodologies, caused by disturbances to the soil’s natural diffusive regime. This study investigates the degree of bias present in four ¹⁴C sampling chamber methods using a three-dimensional numerical soil-atmosphere CO₂ diffusion model. The four chambers were tested in an idealized, surrogate reality by assessing measurement bias with varying Δ¹⁴C and δ¹³C signatures of production, collar lengths, soil biological productivity rates, and soil diffusivities. The static and Iso-FD chambers showed almost no isotopic measurement bias, significantly outperforming dynamic chambers, which demonstrated biases up to 200‰ in some modeled scenarios. The study also showed that ¹³C and ¹⁴C diffusive fractionation are not a constant multiple of one another, but that the δ¹³C correction still works in diffusive scenarios because the change in fractionation is not large enough to impact measured Δ¹⁴C values during chamber equilibration.This is the publisher’s final pdf.

Using Rapid Reviews in Nursing and Midwifery Research: An Example From a Study Commissioned to Inform Policy-Making

Aim: To illustrate the potential use of rapid review approaches in nursing and midwifery research by presenting a worked example from a study conducted to inform policy decision making. Background: Rapid reviews, which can be defined as outputs of a knowledge synthesis approach that involves modifying or omitting elements of a systematic review process due to limited time or resources, are becoming increasingly popular in health research. This paper provides guidance on how a rapid review can be undertaken and discusses the strengths and challenges of the approach. Data source and research design: Data from a rapid review of the literature undertaken in 2015 is used as a worked example to highlight one method of undertaking a rapid review. Implications for nursing: Seeking evidence to inform health policy making or evidence based practice is a process that can be limited by time constraints, making it difficult to conduct comprehensive systematic reviews

International spread of multidrug-resistant Rhodococcus equi

A multidrug-resistant clone of the animal and human pathogen Rhodococcus equi, MDR-RE 2287, has been circulating among equine farms in the United States since the 2000s. We report the detection of MDR-RE 2287 outside the United States. Our finding highlights the risk for MDR-RE spreading internationally with horse movements

The perceptions of key stakeholders of the roles of specialist and advanced nursing and midwifery practitioners

Aim: To explore the perceptions of key stakeholders of the roles of specialist and advanced nursing and midwifery practitioners. Background: There is evidence that the contribution of these roles to patient care is poorly understood. Design: This research took place over 2 months in 2015 and is part of a larger study involving a rapid review to inform policy development on the specialist and advanced nursing and midwifery practice in Ireland. As an added value, a qualitative element involving thematic analysis was undertaken with key stakeholders. Methods: A phenomenological qualitative study was conducted incorporating semistructured interviews with key stakeholders (n = 15). Purposive sampling with maximum diversity was used to recruit a wide range of perspectives. Findings: Participant’s perspectives led to seven themes: Impact of these roles; role preparation, experience and organizational support; specialist and advanced practice roles in an interdisciplinary context; different folks but not such different roles; impact of specialist and advanced practice roles on patient outcomes; barriers and facilitators to enacting specialist and advanced practice roles; future development of these roles. Conclusion: There is acknowledgement of the positive impact of specialist and advanced practitioners; however, the evidence is currently not conclusive. Preparation for these roles needs to reflect changes in the calibre of today’s professional applicants, and organizational support is paramount to their successful execution. The contribution of their activity to patient outcome needs to be made visible to enhance these roles and to justify the development of new roles across a variety of healthcare areas

Empathy at the heart of darkness: empathy deficits that bind the dark triad and those that mediate indirect relational aggression

The dark triad (DT) traits–psychopathy, narcissism and Machiavellianism–have collectively been linked to reduced empathy and increased aggression; however, their association with distinct empathic subtypes remains unclear; and unique links to indirect relational aggression (IRA) have not been delineated. Moreover, whether dark traits should be conceptualized individually, as a dyad or as a triad with a dark core centered around the absence of empathy is debated. The current study examines (i) whether impaired empathy indeed represents a common “dark core” binding Machiavellianism, narcissism, and psychopathy, and (ii) this core explains associations between the dark traits and IRA. Participants (N = 301, 262 F/39 M) completed measures of the DT traits, cognitive and affective empathy components and IRA (Social Exclusion, Malicious Humor and Guilt Induction). The individual traits model without links between narcissism and IRA showed the best fit, suggesting that, at least in the context of IRA, the DT traits are best viewed as three independent personality traits. Distinct cognitive and affective empathy deficits and capacities are seen in the DT. Peripheral responsivity was the only type of empathy deficit associated with all dark traits, but unrelated to IRA. Psychopathy was the strongest indicator of impaired empathy and all IRAs; however, only online simulation, an affect-related cognitive empathy facet, partially mediated the relationships of psychopathy and Machiavellianism with IRA. Whilst the unique pathways for the dark triad traits suggest stronger alignment of psychopathy and Machiavellianism in their empathic deficits and indirect aggression; the data do not support the notion that an unempathic dark core underpinning all three traits drives indirect aggression. This is the first paper delineating the specific empathic deficits involved using a facet approach and their link to indirect forms of aggression. Results therefore inform theoretical models of aggression in the DT and offer some clarity on the debates surrounding the unempathic dark core in the DT

Media representations of opposition to the 'junk food advertising ban' on the Transport for London (TfL) network: A thematic content analysis of UK news and trade press.

BackgroundAdvertising of less healthy foods and drinks is hypothesised to be associated with obesity in adults and children. In February 2019, Transport for London implemented restrictions on advertisements for foods and beverages high in fat, salt or sugar across its network as part of a city-wide strategy to tackle childhood obesity. The policy was extensively debated in the press. This paper identifies arguments for and against the restrictions. Focusing on arguments against the restrictions, it then goes on to deconstruct the discursive strategies underpinning them.MethodsA qualitative thematic content analysis of media coverage of the restrictions (the 'ban') in UK newspapers and trade press was followed by a document analysis of arguments against the ban. A search period of March 1, 2018 to May 31, 2019 covered: (i) the launch of the public consultation on the ban in May 2018; (ii) the announcement of the ban in November 2018; and (iii) its implementation in February 2019. A systematic search of printed and online publications in English distributed in the UK or published on UK-specific websites identified 152 articles.ResultsArguments in favour of the ban focused on inequalities and childhood obesity. Arguments against the ban centred on two claims: that childhood obesity was not the 'right' priority; and that an advertising ban was not an effective way to address childhood obesity. These claims were justified via three discursive approaches: (i) claiming more 'important' priorities for action; (ii) disputing the science behind the ban; (iii) emphasising potential financial costs of the ban.ConclusionThe discursive tactics used in media sources to argue against the ban draw on frames widely used by unhealthy commodities industries in response to structural public health interventions. Our analyses highlight the need for interventions to be framed in ways that can pre-emptively counter common criticisms
