Stability and continuity of women's core beliefs and psychopathological symptoms from pregnancy to one year postpartum

Unhealthy core beliefs are theorized to be stable constructs throughout the life-span, but no research to date, outside of the context of clinical intervention, has addressed this claim over a period of greater than 6 weeks. This study explores the stability and continuity of core beliefs and psychopathological symptoms in a group of women over a major life event and for 1 year subsequently. Eighty-seven women completed measures assessing their core beliefs and psychopathological symptoms during pregnancy and at 6 and 12 months after giving birth. General maternal psychopathological symptoms significantly decreased across the group between pregnancy and 6 months postpartum, and between pregnancy and 1 year, but showed evidence of stability in the ranks of individuals across time. The majority of core beliefs remained both stable and continuous throughout this period of major transition. These findings generally support the theoretical contention that core beliefs are relatively stable and continuous self-constructs. Science+Business Media, LLC.

Is pregnancy a teachable moment for diet and physical activity behaviour change? An interpretative phenomenological analysis of the experiences of women during their first pregnancy

OBJECTIVES: Pregnancy may provide a 'teachable moment' for positive health behaviour change, as a time when women are both motivated towards health and in regular contact with health care professionals. This study aimed to investigate whether women's experiences of pregnancy indicate that they would be receptive to behaviour change during this period. DESIGN: Qualitative interview study. METHODS: Using interpretative phenomenological analysis, this study details how seven women made decisions about their physical activity and dietary behaviour during their first pregnancy. RESULTS: Two women had required fertility treatment to conceive. Their behaviour was driven by anxiety and a drive to minimize potential risks to the pregnancy. This included detailed information seeking and strict adherence to diet and physical activity recommendations. However, the majority of women described behaviour change as 'automatic', adopting a new lifestyle immediately upon discovering their pregnancy. Diet and physical activity were influenced by what these women perceived to be normal or acceptable during pregnancy (largely based on observations of others) and internal drivers, including bodily signals and a desire to retain some of their pre-pregnancy self-identity. More reasoned assessments regarding benefits for them and their baby were less prevalent and influential. CONCLUSIONS: Findings suggest that for women who conceived relatively easily, diet and physical activity behaviour during pregnancy is primarily based upon a combination of automatic judgements, physical sensations, and perceptions of what pregnant women are supposed to do. Health professionals and other credible sources appear to exert less influence. As such, pregnancy alone may not create a 'teachable moment'. Statement of contribution What is already known on this subject? Significant life events can be cues to action with relation to health behaviour change. However, much of the empirical research in this area has focused on negative health experiences such as receiving a false-positive screening result and hospitalization, and in relation to unequivocally negative behaviours such as smoking. It is often suggested that pregnancy, as a major life event, is a 'teachable moment' (TM) for lifestyle behaviour change due to an increase in motivation towards health and regular contact with health professionals. However, there is limited evidence for the utility of the TM model in predicting or promoting behaviour change. What does this study add? Two groups of women emerged from our study: the women who had experienced difficulties in conceiving and had received fertility treatment, and those who had conceived without intervention. The former group's experience of pregnancy was characterized by a sense of vulnerability and anxiety over sustaining the pregnancy which influenced every choice they made about their diet and physical activity. For the latter group, decisions about diet and physical activity were made immediately upon discovering their pregnancy, based upon a combination of automatic judgements, physical sensations, and perceptions of what is normal or 'good' for pregnancy. Among women with relatively trouble-free conception and pregnancy experiences, the necessary conditions may not be present to create a 'teachable moment'. This is due to a combination of a reliance on non-reflective decision-making, perception of low risk, and little change in affective response or self-concept.

Interventions for nurses caring for a child who has an unexpected acute life threatening event (ALTE) in hospital

Introduction: Caring for a child who has an unexpected ALTE in hospital can be stressful. An ALTE may include a cardiac arrest, respiratory arrest or call for immediate assistance. An international survey of practice was conducted to identify any existing interventions to inform a PhD program of work aimed at reducing the stress from these events through preparation and support. Purpose: The purpose of the survey was threefold: (1) Describe ‘normal’ practice when it comes to preparing staff or providing psychological support after caring for a child who has had an ALTE. (2) Determine if there are any interventions to prepare clinical staff for potential psychological effects of caring for a child who has an ALTE. (3) Determine if there are any interventions to provide support for clinical staff after caring for a child who has an ALTE. Material - Methods: An 18 item semi structured questionnaire was designed for the study to allow respondent to describe practices within their institution and outline their opinions and professional experiences. Clinicians from selected children’s and adult hospitals in Australia, Canada, New Zealand, United Kingdom and the United States of America were contacted by telephone. Following consent they were given the option to complete the survey via the telephone, by post or online. Results: Of the 61 hospitals approached 44 (72%) clinicians responded. Eighteen (41%) respondents identified interventions in place to prepare nurses for an ALTE ranging from (but not limited to) ad hoc discussions during life support training through to structured simulation training. Thirty-six (82%) respondents identified that they had interventions in place to support nurses after an ALTE ranging from (but not limited to) debriefing through to structured case reviews. Conclusions: Interventions varied across institutions, with no outcome or evaluation data for the interventions published to date.

Moving beyond heterosexism? The good, the bad and the indifferent in accounts of others’ reactions to important life events

Latterly the psychology of sexualities has diversified. There has been increased engagement with queer theory and a heightened focus on sexual practices alongside continued interrogation of heteronormativity via analyses of talk-in-interaction. In this article, I offer an argument for juxtaposing the incongruent in order to further interrogate manifestations of heterosexism in lesbian, gay, bisexual, trans and queer (LGBTQ) people’s lives. In this case, accounts of others’ reactions to a happy event and to a sad experience. By drawing on two contrasting data corpuses – 124 people planning or in a civil partnership and 60 women who had experienced pregnancy loss – there is increased potential for understanding variation in ‘normative’ and/or heteronormative interpretations of LGBTQ lives. I suggest that, despite significant legal and structural gains for LGBTQ communities in a number of Western countries in recent years, and lively internal debates within the psychology of sexualities field, critical examination of manifestations of heterosexism should remain a central focus.

Exploring the experiences of nurses who care for children who have Acute Life Threatening Events (ALTE) in hospital

This thesis presents a program of work designed to explore and describe what the experience of caring for a child who has an Acute Life Threatening Event (ALTE) is like for the nurses. An ALTE may include a cardiac arrest, respiratory arrest or unplanned admission for a ward to the Paediatric Intensive Care unit. Using the MRC framework for the development of complex interventions, this information was then coupled with theory to develop the PREPARE and SUPPORT interventions. Given the wide-ranging and exploratory nature of this research, a pragmatic, mixed design approach was used to address the aims and objectives of the thesis. The mixed design approach included: a systematic literature review; international survey of practice; interviews with nurses and doctors using Interpretative Phenomenological Analysis; development, refinement and evaluation of interventions during a feasibility study. Two studies were identified through the systematic review which aimed to evaluate the effectiveness of debriefing. The studies did not provide evidence to support the use of these interventions within healthcare. The international survey of practice demonstrated hospitals were using interventions to both prepare and support nurses for these events. The preparatory interventions were clinically focused and the majority of the supportive interventions included a debrief. The interventions were not being evaluated for effectiveness. The interviews conducted with nurses and doctors provided insight into what that experience was like for the participants. Using the MRC framework, this evidence was coupled with theory to develop the PREPARE and SUPPORT interventions. A multidisciplinary working party used an iterative process to refine and evaluate the interventions and study procedures were explored through a feasibility study. The pragmatic, mixed design approach demonstrated how the empirical evidence was coupled with theory and clinical expertise to develop interventions for use within the healthcare environment.

Modular ESS with second life batteries operating in grid independent mode

This work is part of a bigger project which aims to research the potential development of commercial opportunities for the re-use of batteries after their use in low carbon vehicles on an electricity grid or microgrid system. There are three main revenue streams (peak load lopping on the distribution Network to allow for network re-enforcement deferral, National Grid primary/ secondary/ high frequency response, customer energy management optimization). These incomes streams are dependent on the grid system being present. However, there is additional opportunity to be gained from also using these batteries to provide UPS backup when the grid is no longer present. Most UPS or ESS on the market use new batteries in conjunction with a two level converter interface. This produces a reliable backup solution in the case of loss of mains power, but may be expensive to implement. This paper introduces a modular multilevel cascade converter (MMCC) based ESS using second-life batteries for use on a grid independent industrial plant without any additional onsite generator as a potentially cheaper alternative. The number of modules has been designed for a given reliability target and these modules could be used to minimize/eliminate the output filter. An appropriate strategy to provide voltage and frequency control in a grid independent system is described and simulated under different disturbance conditions such as load switching, fault conditions or a large motor starting. A comparison of the results from the modular topology against a traditional two level converter is provided to prove similar performance criteria. The proposed ESS and control strategy is an acceptable way of providing backup power in the event of loss of grid. Additional financial benefit to the customer may be obtained by using a second life battery in this way.

Stretching the life of Twitter classifiers with time-stamped semantic graphs

Social media has become an effective channel for communicating both trends and public opinion on current events. However the automatic topic classification of social media content pose various challenges. Topic classification is a common technique used for automatically capturing themes that emerge from social media streams. However, such techniques are sensitive to the evolution of topics when new event-dependent vocabularies start to emerge (e.g., Crimea becoming relevant to War Conflict during the Ukraine crisis in 2014). Therefore, traditional supervised classification methods which rely on labelled data could rapidly become outdated. In this paper we propose a novel transfer learning approach to address the classification task of new data when the only available labelled data belong to a previous epoch. This approach relies on the incorporation of knowledge from DBpedia graphs. Our findings show promising results in understanding how features age, and how semantic features can support the evolution of topic classifiers.
