Exploring career change through the lens of the intelligent career framework

This study explores what motivates engineers in their early-mid career to change careers. It first establishes the definition of a career change from the perspective of those who have changed careers, and then examines what drives, influences and facilitates a career change, as well as how a career change is enacted physically and emotionally. This has been looked at through the contemporary lens of the ‘intelligent career framework’. This research adopted a qualitative, abductive approach following an initial inductive small-scale exploratory study. The fieldwork consisted of a pilot and main study using semi-structured interviews. For the main study, 22 interviews were conducted within one organisation in order to elicit the subjective experiences of engineers who had undertaken a career change. The findings show how the driving factors relate predominantly to knowing-why and knowing-where. The influencing and facilitating factors vary by individual, and relate to knowing-what, knowing-how knowing-when and knowing-whom. Six clusters of interacting factors were observed with knowing-why, knowing-how and knowing-when at the core. Whilst the process of career change was complex and long, differing pathways through which individuals changed careers were evident, as well as emotions that needed to be managed. This study contributes to knowledge in the area of contemporary career theory by exploring career change through a new lens: the intelligent career framework. It demonstrates how individuals use their ‘career capital’ to effect a career change and the ways in which the six knowings interact to bring about a career change. It extends the understanding of the process of career change and discovers some of the organisational factors that influence or facilitate individuals making a career change. All of these contributions address identifiable gaps in the literature

A GIS-based decision support tool for optimisation of marine cage siting for aquaculture: A case study for the Western Isles, Scotland.

Scotland’s coastal environment has many areas which are potentially suitable for sustainable aquaculture development. However previous studies have shown that aquaculture may have a detrimental impact on sensitive environments. The main objective of this study is to develop a holistic management tool for sustainable coastal marine aquaculture in the Western Isles of Scotland through development of a multi-faceted holistic model that allows consideration of sensitive environments. As the Scottish Government promotes better collaboration and integration of all involved in coastal zone governance (Baxter et al, 2008) this study illustrates the benefits to be gained from harmonized management of information in a Geographical Information System. GIS models are strong support tools designed to aid decision-making. The main strengths are that GIS can generate easily understandable visual displays of results which are based on robust models capable of incorporating vast amounts of spatial data and which can be predictive and can simulate future coastal environment scenarios. Within this study it is demonstrated that GIS-based models can successfully manage and manipulate a wide range of datasets that are essential components in the determination and management of suitable aquaculture locations. The GIS decision support tools evaluated and integrated in this study were based on four main sub models. These were Cage Site Suitability, Particulate Dispersion, Sensitivity Biodiversity Indicators and Visual Landscape Capacity. Exploration of a combination of these sub-models into an overall decision support system was also completed. All sub models developed were flexible, instrumentally coherent and communicatively balanced for the management and planning of the coastal environment . A sub-model was designed to evaluate and optimize the location of marine cage systems. This required development of data layers and modelled sub-components relevant to the important environmental and engineering factors affecting cage designs which included wave climate, bathymetric and substrate profiles. Three cage types were explored; those designed for sheltered, semi-exposed and exposed areas. These environmental factor layers were combined through weighting and Multi criteria evaluation consideration for each cage type. The resulting three sub-models indicated that while the archipelago has quite restricted development potential for cages designed for sheltered environments (91km2), there is a limited development potential for cages designed for semi exposed environments (1543km2) and an optimal potential for aquaculture development with cages designed for exposed environments (3103km2). The greatest potential environmental impact from aquaculture comes from particulate dispersion. Currently, assessing footprints of effect from fish farms is carried out on an individual site basis mostly at ten metre resolution. The sub-model successfully developed in this work resulted in a partially validated multisite particulate sub model at one metre resolution which implemented maximum current velocity as the friction/force image. The sub-model was run on a range of coastal loch fjord systems and demonstrated the variation in particulate dispersion patterns in each fjord system. In all the fjord systems modelled, even where farm sites are close neighbours, there appears to be minimal interaction in the particulate dispersion. While the particulate sub-model is effective and rapid to deploy for multiple sites, it requires further development in order to incorporate the quantitative aspects of particulate dispersion. Aquaculture biodiversity sensitivity indicators were evaluated and five main sub-components were developed; Species sensitive to Aquaculture, Endangered species, Species important to the Western Isles, important spawning and nursery areas and Protected Areas. The sub-model was constructed by combining these layers through weighting and Multicriteria evaluation. The outcomes indicated that within the study area there are 1168km2 (4% of study area) which are highly sensitive to aquaculture activity, although 20595km2 (65% of study area) has a biodiversity that is much less sensitive to aquaculture. This sub-model, and some of its components, can operate as a “stand alone” tool or can be combined into a larger framework. Little modification and re-parameterisation would be required to enable models to be developed to cover the whole of the Scottish coastline, or other coastal locations. Aquaculture can visually affect landscapes, seascapes and can adversely affect visual capacity of different areas. GIS was successfully applied to investigate this contentious issue. This comprehensive and flexible sub-model successfully develops Seascape and Landscape sensitivity analysis of aquaculture structures and also incorporated a novel approach to visual assessment through use of proportional assessment. Combining the sensitivity layers, 6448km2 of the waters of the archipelago (20% of study area) were categorized as having high capacity to incorporate new aquaculture developments, whilst 3301km2 (10% of study area) have a moderate capacity for new aquaculture structures and 1324km2 (4% of study area) have a low capacity for new developments. An overall conceptual framework was designed to explore two methods for the combination of the major sub-models in order to identify the most appropriate areas for sustainable aquaculture with consideration of possible conflicts including conservation issues. Initial evaluations involved the extraction of information from the component GIS sub-models into a structured database. The extracted data provides a range of information that can be used for statistical analysis and decision support, but which leaves the evaluation of the optimal siting of aquaculture at any location in the Western Isles in the hands of the database interrogator. The second method involved combining the sub-models within GIS whole considering trade offs in relation to conservation. This GIS combination of models indicated that, taking many factors into consideration, the Western Isles has 748km2 (2.5% of study area) appropriate for aquaculture development when implementing the C315 and whilst considering the interactions with conservation areas. There were 498km2 (1.6% of study area) appropriate for development when implementing the intermediate C250 cage types but only 15km2 (0.04% of study area) were appropriate for development based on the LMS cage designs for sheltered environments. Both analytical approaches had strengths and weakness and clearly both need to be used in combination to maximise the benefit of the GIS model outcomes. This study has demonstrated the ability to apply scientific rigour to spatial modelling of aquaculture problems including site suitability, biodiversity, landscape capacity and multi-site particulate dispersion. The various sub-models and their components sub-models can be stand-alone decision-making tools or combined into a holistic model which incorporates a flexible method of trade-off management. The range of GIS-based coastal analytical tools developed form the core of a decision support system that can enable the objective management of the increasing demands on the coastal zone, while having the capacity to bring together stakeholders, multiple agencies and governing bodies that are responsible for management and use of these precious and sometimes threatened resources

Sex Differences with Aging in the Fatigability of Dynamic Contractions

This study determined the sex difference with aging in fatigability of the elbow flexor muscles during a dynamic fatiguing task, and explored the associated mechanisms. We compared fatigability of the elbow flexor muscles in 18 young (20.2 ± 1 years: 9 men) and 36 old adults (73.5 ± 1 years: 16 men) during and in recovery from repeated dynamic contractions (~ 60°/s) with a load equivalent to 20% of maximal voluntary isometric contraction (MVIC) torque until failure. Transcranial magnetic stimulation (TMS) was used to assess supraspinal fatigue (an increase in the superimposed twitch, SIT) and the peak rate of muscle relaxation. Time to failure was briefer for the men than the women (6.1 ± 2.1 vs. 9.7 ± 5.5 min, respectively; P = 0.02) with no difference between young and old adults (7.2 ± 2.9 vs. 8.4 ± 5.2 min, respectively, P = 0.45) and no interaction (P \u3e 0.05). The relative decline in peak relaxation rate with fatigability was similar for young and old adults (P = 0.11), but greater for men than women (P = 0.046). Supraspinal fatigue increased for all groups and was associated with the time to failure (P \u3c 0.05). Regression analysis however, indicated that the time to failure was best predicted by the peak relaxation rate (baseline values and slowing with fatigability) (r2 = 0.55). Rate-limiting contractile mechanisms (e.g. excitation–contraction coupling) were responsible for the increased fatigability of the elbow flexors of men compared with women for a dynamic fatiguing task of slow angular velocity, and this sex difference was maintained with aging. The age difference in fatigability for the dynamic task was diminished for both sexes relative to what is typically observed with isometric fatiguing contractions

Maximum fidelity retransmission of mirror symmetric qubit states

In this paper we address the problem of optimal reconstruction of a quantum state from the result of a single measurement when the original quantum state is known to be a member of some specified set. A suitable figure of merit for this process is the fidelity, which is the probability that the state we construct on the basis of the measurement result is found by a subsequent test to match the original state. We consider the maximisation of the fidelity for a set of three mirror symmetric qubit states. In contrast to previous examples, we find that the strategy which minimises the probability of erroneously identifying the state does not generally maximise the fidelity

A survey of smoking cessation training within UK Pharmacy education

Introduction: Tobacco smoking is a significant public health problem, and remains the leading cause of preventable, premature death in the UK. In order to reduce the burden of smoking in the UK, all healthcare professionals should be able to advise and assist smokers to quit. Adequately trained pharmacists can play a key role in providing smoking cessation support and advice. The aim was to identify the extent of smoking cessation teaching and examination in UK pharmacy schools.Methods: A short survey of smoking cessation was sent to each Programme Director for all UK pharmacy schools (n=29). Results: The survey achieved a response rate of 72%. All schools dedicated time teaching smoking cessation interventions, with 76% spending more than three hours, and 90% examining students on some aspect of smoking cessation. All schools taught about Nicotine Replacement Therapy (NRT) and the role of behavioural support. At least 90% of schools taught about the role of the stop smoking services; and opportunistic brief interventions, e.g. Very Brief Advice (VBA). Only 14% covered practical delivery in clinical settings.Conclusions: UK pharmacy schools are teaching and examining students on a wide range of smoking cessation interventions, including VBA. However, there was a lack of training reported on the management of mental health patients who smoke, and practical skills training. All schools should do more to ensure they are providing practical skills training to enable students to be adequately prepared for delivering smoking cessation support to all smokers, including vulnerable populations

The use of SIFT-MS in profiling the faecal volatile metabolome in horses with colic: a pilot study

SIFT-MS is used for the first time in profiling the volatile organic profile in faecal headspace in two groups of horses admitted to an equine hospital, one group with acute intestinal disease (colic) affecting the large colon, plus a control group of similarly managed horses admitted for non-gastrointestinal/metabolic reasons (e.g. acute orthopaedic injury). Compounds in faecal headspace which show statistically significant concentration differences between the groups are acetone and methanol. In addition, some ions at various m/z values show significantly different ion counts between the groups. Further information may be gleaned by using multivariate statistics in evaluating the differences between the two horse groups. Principal components analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) were evaluated for reducing the dimensionality of the SIFT-MS data, and OPLS-DA was found to be best at discriminating between the groups, particularly with SIFT-MS data acquired using the H3O+ precursor ion. Analysis of these data also show the significance of ammonia as a discriminating ion. These results show that SIFT-MS may potentially be used on the headspace of horse faecal samples for detecting altered microbial fermentation associated with acute intestinal disease of the colon

What do working menopausal women want? A qualitative investigation into women’s perspectives on employer and line manager support

Objectives: To explore women’s perspectives on what employers and managers should, and should not do in relation to women going through the menopause at work. Methods: An online questionnaire was used to collect qualitative data in a cross-sectional study of working women. Three open-ended questions asked peri- and post-menopausal women, aged 45-65 years: (i) what they thought employers could do, or should do, to help menopausal women who may be experiencing difficult menopausal symptoms at work; (ii) how managers should behave, and (iii) how managers should not behave towards women going through the menopause. Results: 137 women responded to the open questions in the survey. An inductive thematic analysis was conducted and three overarching themes emerged. Theme 1 related to employer/manager awareness, specifically to knowledge about the menopause and awareness of how the physical work environment might impact on menopausal women. Theme 2 related to employer/ manager communication skills and behaviors, specifically, those considered helpful and desired and those unhelpful and undesired. Theme 3 described employer actions, involving staff training and raising awareness, and supportive policies such as those relating to sickness absence and flexible working hours. Conclusions: The menopause can be difficult for some women to deal with at work partly due to the working environment. To our knowledge, this is the first study to explore women’s descriptions of how they would like to be treated by employers/managers, and what would be helpful and unhelpful. The results have clear implications for communication about menopause at work and for employer-level policy and practice

Spatiotemporal Statistical Downscaling for the Fusion of In-lake and Remote Sensing Data

This paper addresses the problem of fusing data from in-lake monitoring programmes with remote sensing data, through statistical downscaling. A Bayesian hierarchical model is developed, in order to fuse the in-lake and remote sensing data using spatially-varying coefficients. The model is applied to an example dataset of log(chlorophyll-a) data for Lake Erie, one of the Great Lakes of North America

Humour styles as moderators and mediators of the relationship between peer-victimisation and internalising

Peer-victimisation is associated with numerous, negative psycho-social outcomes and meta-analyses indicate that internalising difficulties are particularly salient. Given the inherently social nature of humour, and previous work supporting the association of humour with wellbeing, we investigated whether specific humour styles mediated or moderated the relationship between peer-victimisation and depressive symptomatology. Peer-reports of physical, verbal, and indirect peer-victimisation were collected for 1,241 English adolescents aged 11-13 years old. Self-reports of humour style and depression were also collected. Analyses using Structural Equation Modeling revealed no moderation by humour was evident. Verbal victimisation had the largest association with depressive symptomatology and a positive association between verbal victimisation combined with large, positive association between self-defeating humour and depressive symptomatology provides evidence for an indirect pathways via self-defeating humour use. The implications of these results for our understanding of peer-victimisation, adjustment, and humour are considered
