Marketing career transitions: women marketers embedded in the profession?
This qualitative study explores a UK sample of 25 women marketing professionals and how their career paths are reached and moderated over time. The research addresses the women‟s reasons for moving from corporate marketing careers to self-employment in marketing and discovers that their career anchor is their embeddedness in the marketing profession which remains a constant throughout their career. This suggests that marketing talent is being lost to the corporate environment but not necessarily to the profession. It also suggests that the profession needs to acknowledge these career transitions when offering support to those practicing marketing
The Richtmyer–Meshkov instability in magnetohydrodynamics
In ideal magnetohydrodynamics (MHD), the Richtmyer–Meshkov instability can be suppressed by the presence of a magnetic field. The interface still undergoes some growth, but this is bounded for a finite magnetic field. A model for this flow has been developed by considering the stability of an impulsively accelerated, sinusoidally perturbed density interface in the presence of a magnetic field that is parallel to the acceleration. This was accomplished by analytically solving the linearized initial value problem in the framework of ideal incompressible MHD. To assess the performance of the model, its predictions are compared to results obtained from numerical simulation of impulse driven linearized, shock driven linearized, and nonlinear compressible MHD for a variety of cases. It is shown that the analytical linear model collapses the data from the simulations well. The predicted interface behavior well approximates that seen in compressible linearized simulations when the shock strength, magnetic field strength, and perturbation amplitude are small. For such cases, the agreement with interface behavior that occurs in nonlinear simulations is also reasonable. The effects of increasing shock strength, magnetic field strength, and perturbation amplitude on both the flow and the performance of the model are investigated. This results in a detailed exposition of the features and behavior of the MHD Richtmyer–Meshkov flow. For strong shocks, large initial perturbation amplitudes, and strong magnetic fields, the linear model may give a rough estimate of the interface behavior, but it is not quantitatively accurate. In all cases examined the accuracy of the model is quantified and the flow physics underlying any discrepancies is examine
Fire and rescue service community safety initiatives: measuring impact
Purpose - The purpose of this paper is to discuss methods of capturing the impact of fire and rescue service (FRS) community safety work which directly aims to reduce the occurrence of specific incidents. Design/methodology/approach - The impact assessment method described focuses on addressing one of the major problems with regards to attributing outcomes to FRS community safety work; the influence of external factors. This paper looked to assess the incident trends within a case study UK FRS within the context of the following external data sets: first, incident trends within other UK FRSs; second, demographic trends; and third, incident data from other public services. Findings - There were instances, either across the whole region served by the case study FRS, or within specific districts, where evidence suggested a strong likelihood of the community safety work of the case study FRS contributing towards an observed reduction in incidents. These findings were established through filtering the impact of widespread external factors, which could impact upon incident figures. Research limitations/implications - The utility of this impact assessment relies upon FRS consistently recording the specific aims and focus of individual community safety activity, so that any positive outcomes can be attributed to a particular group of community safety initiatives. Originality/value - This paper discusses how an evaluation process, to deter mine the likelihood of community safety impacting upon incident numbers, can be practically applied to a FRS

Marketing women in Iceland: challenges of establishing a company
Objectives: This paper explores the experiences of nine
Icelandic business women who that have their own marketing businesses. In recent years more women graduated from Icelandic universities than men (Statistic Iceland, 2012a) where business and marketing studies have proved popular. Little is known though about the experiences of Icelandic women moving into self-employment in marketing, particularly in relation to challenges of setting up and managing their own business. Iceland provides a unique context as it is a small island with only 325.000 habitants (Statistic Iceland, 2014). The country was hit badly by the economic crisis in 2008 which is likely to have affected the career and business decisions of self-employed women. Prior Work: Marketing is considered to be a female-oriented industry but experiences of women working in marketing are an under-researched area (Maclaren and Catterall, 2000). In addition, Marlow et al.,(2009) called for studies focusing on the challenges of the entrepreneurial environment for women. Some of the challenges that women owning their own business have to face have been identified as capitalisation, working hours and location (Carter et al., 2001; Roper and Scott, 2009; Harding, 2006). These experiences will be discussed in this paper. Approach: This paper builds on work from a similar study already undertaken in the UK by Foster and Brindley (2010); Foster et al., (2011) and Wheatley at al., (2011) and their investigation of marketing businesses in the UK but explores the experiences in the novel context of Iceland which is a much smaller economy and often heralded as a beacon of gender equality (Petterson 2012; Acthenhagen and Tilmar, 2013). The study takes an exploratory, qualitative approach. Convenience sampling was used for the study with nine Icelandic women who owned a marketing business. All the interviews were conducted with the owner of the company using a set of questions around a priori themes drawn from the literature. The interviews took place in August 2013. Results: Preliminary analysis indicates that Icelandic women are cautious when it comes to capitalisation. They are quite reluctant to take out a loan to finance their business. In addition the majority seemed to work long hours, often nights and weekends. Full findings will be presented at the conference. Implications: These findings give the first account of experiences of Icelandic self-employed women in marketing and answers recent calls for studies in the field of marketing and the entrepreneur environment for women (Maclaren and Catterall, 2000; Marlow et al.,2009). Value: This paper provides an insight into the experiences of the Icelandic business women working in marketing. In addition it offers comparisons with previous studies conducted in the UK

An exploration of Icelandic marketing entrepreneurs
Little research have focused on women entrepreneurship in Iceland and yet it is often heralded as a beacon of gender equality (Pettersson, 2012; Achtenhagen and Tilmar, 2013; Smith-Hunter, 2013). The World Economic Forum (2013) identified Iceland as the country with the world's smallest gender gap. This small gender gap is not reflected in the entrepreneurship figures which show that only 8 percent of Icelandic women are classed as entrepreneurs (GEM, 2009) compared to 15 percent of men. Furthermore, Danson and Burnett (2013) posited that entrepreneurship in island environments is an under-researched area. It is therefore pertinent to explore what is happening in terms of women’s entrepreneurship in Iceland. The paper builds upon similar studies already undertaken in the UK and Europe (see Foster et al., 2011 and Wheatley et al, 2011) that have investigated the careers of marketing professionals through their life-courses. Marketing is considered to be a feminised industry in Iceland yet there is little knowledge about the careers these women have in the profession or why they decide to become self- employed. The findings showed the most often women became self-employed because of a trigger event and it seemed in most cases to be the financial crises in 2008

Working 9 to 5? Complex patterns of time allocation among managers and professionals in dual career households
This PhD is a theoretically informed empirical investigation of contemporary patterns of time allocation among managers and professionals in dual career households. Focus centres on three key elements of time allocation, namely work, care and commuting. Specifically, this thesis addresses three research questions: (1) Which theoretical approach(es) — mainstream, institutional or feminist — offer the most suitable explanation of individual and household choices and constraints in the allocation of time? (2) Do distinctions need to be made within the Professional-Managerial Class (PMC), and are these distinctions occupational and/or gender specific? (3) What challenges, in a policy context, do dual career households face in managing the combined demands of work-time, caring and commuting? A mixed methods approach is employed. This combines quantitative empirical analysis using published national statistics, specifically the Labour Force Survey (LFS) and the Census Special Licence Household Sample of Anonymised Records (SL-HSAR), with a mixed methods case study of Greater Nottingham, a major employment centre of the East Midlands region of the UK. The case study comprises a series of interviews with Human Resource Managers (HRMs) and a survey of managerial and professional workers. It allows analysis at two reference points, using primary data collected as part of the ‘location and mobility decisions of dual career households’ project funded by the Leverhulme Trust (grant F/740)
Calculating the inherent visual structure of a landscape (inherent viewshed) using high-throughput computing
This paper describes a method of calculating the inherent visibility at all locations in a landscape (‘total viewshed’) by making use of redundant computer cycles. This approach uses a simplified viewshed program that is suitable for use within a distributed environment, in this case managed by the Condor system. Distributing the calculation in this way reduced the calculation time of our example from an estimated 34 days to slightly over 25 hours using a cluster of 43 workstations. Finally, we discuss the example ‘total viewshed’ raster for the Avebury region, and briefly highlight some of its implications
Argumentative Synthesis Essay on Enhanced Interrogation Techniques
This essay discusses enhanced interrogation techniques. For reference, enhanced interrogation techniques are interrogation techniques that involve “physically coercive interventions” (Duke & Puyvelde, 2017). The U.S. government supported these techniques after the attacks on September 11, 2001. This essay argues that enhanced interrogation techniques should not be used in interrogations because they are unethical, ineffective, and negatively impact the mental health of the interrogators using these techniques. Additionally, the essay references articles on the varied viewpoints as well as explains information on these interrogation techniques. Also, the essay argues that enhanced interrogation techniques encourage people to be cruel and inhumane. Moreover, there is evidence that interrogations involving torture actually bring out lies and false-memories--instead of the truth--from detainees. For example, in the “Committee Study of the Central Intelligence Agency’s Detention and Interrogation Program,” the Senate Select Committee on Intelligence talks about how the CIA unsuccessfully got credible intelligence information from detainees through enhanced interrogation techniques. Furthermore, these interrogation techniques cause major psychological problems for the interrogators using these techniques, such as “burn out” and PTSD (Dee, 2017). However, the essay mentions that some people support enhanced interrogation techniques because they think the detainees receiving the torture deserve it and that it is effective. The essay refutes these claims by saying that torture is against human rights and that science shows that torture is ineffective in interrogations. To conclude, the essay claims that there are ethical interrogation techniques that can bring out more reliable information than enhanced interrogation techniques
