The Capital Sculpture of Wells Cathedral, c. 1184-1210

The understudied capital sculpture of Wells Cathedral in Somerset, England (c. 1184-1210) provides ample opportunity of expanding the current scholarship and understanding of interior ecclesiastical sculpture in a West Country cathedral. While the Gothic style of architecture is typically understood as, according to Paul Binski (2014), rational in execution and reception, the capital sculpture at Wells Cathedral has been considered illogical in terms of both its iconography and location within the nave, transepts, and north porch. Utilizing Michael Camille’s post/anti-iconographical approach, this project examines the Wells figural capitals in five case studies: labour, Old and New Testament Scenes, animals and beast fables, busts, and monsters and hybrids. Each group of capitals will be approached with an understanding that this type of art was viewed by people of different classes and professions, with each viewer bringing their own personal experiences and abilities into how they could have read and understood these types of images. Therefore, the capitals at Wells must be read through layers of meaning and interpretation while also considering their locations within the cathedral and how they react and respond to surrounding figural capitals.

Rethinking Professional Practice: The Logic of Competition and the Crisis of Identity in Housing Practice

The relationship between professionalism, education and housing practice has become increasingly strained following the introduction of austerity measures and welfare reforms across a range of countries. Focusing on the development of UK housing practice, this article considers how notions of professionalism are being reshaped within the context of welfare retrenchment and how emerging tensions have both affected the identity of housing professionals and impacted on the delivery of training and education programmes. The article analyses the changing knowledges and skills valued in contemporary housing practice and considers how the sector has responded to the challenges of austerity. The central argument is that a dominant logic of competition has culminated in a crisis of identity for the sector. Although the focus of the article is on UK housing practice, the processes identified have a wider relevance for the analysis of housing and welfare delivery in developed economies.

Impact of the Financial Crisis on the Performance of European Acquisitions

This study looks at the impact of the recent financial crisis on the short-term performance of European acquisitions. We use institutional theory and transaction cost economic theory to study whether bidders derive lower or higher returns from acquisitions announced after 2008. We investigate shareholders’ stock price reaction to 2245 deals which occurred during 2004–12 across 22 European Union countries. Our results from both univariate and multivariate analysis show that the deals announced in the post-crisis period, corresponding to the period of economic recession, generate higher returns to shareholders as compared to acquisitions announced in the pre-crisis period. We also test the relevance of the Economic and Monetary Union (EMU), that is, the Eurozone, to this value accrual during the recessionary period. We observe that non-EMU transactions obtain significantly higher gains vis-à-vis EMU transactions in the post-crisis years. Overall, announcement returns of European acquisitions have been affected by the financial crisis and the global recession; and companies that target countries with different currency regimes are likely to generate better returns from their acquisitions.

Mad Men, The Sopranos and The American Way of Life. The history of the capital in two times

Don Draper (Mad Men, Matthew Weiner, AMC: 2007-2015) actively colaborates in the birth and consolidationof a model of consumer society without realizing the enormous lie he is telling himself. Tony Soprano(The Sopranos, David Chase, HBO: 1999-2007) desperately grasps the wreckage of that ideal imageof effort and self-improvement which is not only disappearing but was actually never coherent or real.This article does a comparative textual, sociological, and discursive analysis these two characters as arepresentation of the evolution of the discourse of capitalism in the second half of the 20th century, that is,the artificiality of the hegemonic discourse of “pursuit of happiness” as the main myth in post-war NorthAmerican neoliberalism.

The impact of political and economic crisis on the polarization of the Spanish media

In this paper the characteristics of the cyclical political polarization of the Spanish media system are defined. From this study, a prospective analysis raises doubts about this scenario remains unchanged because of the political and economic crisis. It seeks to define the role played by political and media actors in polarization focusing on the two legislatures where the tension reached higher levels (1993-1996 and 2004-2008) and compares it with the developments faced by them in the current economical and political context of crisis. To achieve these aims, it has been performed an analysis of media content (since 1993) and looked through primary sociological sources and the scientific literature about polarization. This is an exploratory, critical and descriptive case analysis.

On the Capital Structure of Real Estate Firms

The leverage and debt maturity choices of real estate companies are interdependent, and are not made separately as is often assumed in the literature. We use three-stage least squares (3SLS) regression analysis to explore this interdependence for a sample of listed U.S. real estate companies and Real Estate Investment Trusts (REITs) traded between 1973 and 2006.We find substantial differences in the nature of the relationship between leverage and maturity for the two firm types. Leverage is a determinant of maturity for non-REITs, whereas maturity is a determinant of leverage for REITs. We also find that the drivers of capital structure choices in real estate companies and REITs clearly reflect the effects of the REIT regulation.

Shining a Light on the Dark Side: How the Global Financial Crisis Exposed the Dark Side of Leadership

The global financial crisis has had innumerate outcomes around the globe. Whilst most of these are generally perceived to be negative, there are outcomes which could be considered positive for society. One such outcome is the spotlight that the financial crisis has shone on corruption within organisations and in particular, the role that destructive leaders play in the promotion of negative behaviours within organisations. This interest in identifying so-called ‘dark-side’ traits in leaders is a positive step both academically and practically. Academically, there is a limited research examining individuals with ‘dark-traits’ within organisations (Mahmut, Homewood & Stevenson, 2008). Practically, most leader derailment can be attributed to ‘dark-side’ traits and leaders with such traits are implicated in a host of issues for organisations including poor staff morale and satisfaction, bullying, poor levels of productivity, high staff turnover, unethical behaviour and even white collar crime (e.g. Boddy,2010; 2011; Lesha & Lesha, 2012; O’Boyle, Forsyth, Banks & McDaniel, 2012; Sanecka, 2013). This paper focuses on one of the ‘dark-side’ traits; psychopathy. Psychopathy is a personality disorder characterised by guiltlessness, incapacity to experience love, impulsivity, shallow emotions, superficial charm and an inability to learn from experience (Cleckley, 1941, 1982). Research has found that individuals with high levels of psychopathy can be found working within organisations and experiencing some degree of career success (e.g. Babiak, Neumann & Hare, 2010; Board & Fritzon, 2005; Boddy, 2010; Lilienfeld, Latzman, Watts, Smith & Dutton, 2014). These individuals are theoretically thought to be attracted to careers which offer power, status and monetary rewards. In particular, the finance industry has been suggested as an ideal work place for the organisational psychopath. Some authors go as far as attribute organisational psychopaths a key role in the financial crisis (Boddy, 2011). However, little research has been conducted to explore whether levels of psychopathy in employees differ across industries and what careers might be most attractive to individuals with high levels of psychopathy. This paper presents the results of a large scale survey of 265 alumni of universities in the Central England region of the UK. The survey was conducted to assess the link between levels of three factors of psychopathy (Egotism, Callousness and Antisocialism) with occupation as defined by Holland’s RIASEC model. Participants completed Brinkley, Diamond, Magaletta & Heigel’s (2008) revision of Levenson’s Self-Report Psychopathy Scale and responded to questions regarding their current occupation. Logistic regression analyses were conducted to assess whether levels of Egotism, Callousness and Antisocialism were predictive of occupation. The results showed that when compared to individuals who occupy job roles within the Social sector of Holland’s model, individuals with higher levels of psychopathy were more likely to be employed within Realistic, Investigative, Enterprising and Conventional roles. When comparing Social and Realistic roles, more Egotistical individuals were likely to be employed within Realistic roles. When comparing those employed in Social roles to Investigative, Enterprising and Conventional roles, individuals with higher levels of Antisocialism were more likely to be employed within the latter three occupations than within Social roles. This suggests that individuals with psychopathy do gravitate towards certain career paths. Social roles where job incumbents are required to be caring and interact with others to a large extent appear to be unattractive to individuals with high levels of psychopathy. Social roles are also associated with lower monetary rewards and are generally less prestigious (Henley, 2001). These individuals instead seek out occupations where there are higher levels of risk, power and reward. Roles in the Realistic category include those which include high levels of risk e.g. fighter pilot, fireman etc., (Cohen, Meir, Segal & Amar, 2003). Investigative careers hold the highest level of prestige and ranking. Enterprising roles include management positions where power is wielded over subordinates and sales roles, where customers can be manipulated (ACT, 2009). Conventional roles include those within the finance industry, which include some of the most financially lucrative positive available (Babiak & Hare, 2006). The above suggests that individuals with higher levels of psychopathy may be seeking to satisfy their self-centred natures by selecting careers which provide them with high levels of reward in one way or another. Alternatively, these individuals may select roles where their traits can be accepted. The importance of Antisocialism in predicting occupation may be testament to the importance of finding a career which ‘fits’ such traits. Antisocialism is generally associated with negative outcomes in the workplace (Ettner, MacLean & French, 2010). Therefore, finding environments tolerant of antisocial tendencies may be a priority for individuals with high levels of these traits. The results suggest that Enterprising, Investigative and Conventional work environments may be tolerant of Antisocialism in employees and Realistic environments tolerant of Egotism. Academically, the results show that there is value in studying ‘dark-side’ characteristics in organisations. Individuals with higher levels of psychopathic traits, do not appear to randomly enter employment. Instead, they appear to gravitate to careers which meet their needs and/or tolerate their traits. It is important to further explore what industries and positions are particularly attractive to individuals with higher levels of psychopathy and what makes them attractive to these individuals. Such knowledge is important for practitioners to be able to advise organisations as to the likely level of risk they face of employing organisational psychopaths and to enable organisations which are particularly attractive to highly psychopathic employees to design selection systems which detect undesirable traits in candidates. Furthermore, organisations can examine their culture to assess whether traits such as antisocialism are tolerated (or even rewarded) and what the implications of this are.

Quantification of the human postural control system to perturbations

Human standing posture is inherently unstable. The postural control system (PCS), which maintains standing posture, is composed of the sensory, musculoskeletal, and central nervous systems. Together these systems integrate sensory afferents and generate appropriate motor efferents to adjust posture. The PCS maintains the body center of mass (COM) with respect to the base of support while constantly resisting destabilizing forces from internal and external perturbations. To assess the human PCS, postural sway during quiet standing or in response to external perturbation have frequently been examined descriptively. Minimal work has been done to understand and quantify the robustness of the PCS to perturbations. Further, there have been some previous attempts to assess the dynamical systems aspects of the PCS or time evolutionary properties of postural sway. However those techniques can only provide summary information about the PCS characteristics; they cannot provide specific information about or recreate the actual sway behavior. This dissertation consists of two parts: part I, the development of two novel methods to assess the human PCS and, part II, the application of these methods. In study 1, a systematic method for analyzing the human PCS during perturbed stance was developed. A mild impulsive perturbation that subjects can easily experience in their daily lives was used. A measure of robustness of the PCS, 1/MaxSens that was based on the inverse of the sensitivity of the system, was introduced. 1/MaxSens successfully quantified the reduced robustness to external perturbations due to age-related degradation of the PCS. In study 2, a stochastic model was used to better understand the human PCS in terms of dynamical systems aspect. This methodology also has the advantage over previous methods in that the sway behavior is captured in a model that can be used to recreate the random oscillatory properties of the PCS. The invariant density which describes the long-term stationary behavior of the center of pressure (COP) was computed from a Markov chain model that was applied to postural sway data during quiet stance. In order to validate the Invariant Density Analysis (IDA), we applied the technique to COP data from different age groups. We found that older adults swayed farther from the centroid and in more stochastic and random manner than young adults. In part II, the tools developed in part I were applied to both occupational and clinical situations. In study 3, 1/MaxSens and IDA were applied to a population of firefighters to investigate the effects of air bottle configuration (weight and size) and vision on the postural stability of firefighters. We found that both air bottle weight and loss of vision, but not size of air bottle, significantly decreased balance performance and increased fall risk. In study 4, IDA was applied to data collected on 444 community-dwelling elderly adults from the MOBILIZE Boston Study. Four out of five IDA parameters were able to successfully differentiate recurrent fallers from non-fallers, while only five out of 30 more common descriptive and stochastic COP measures could distinguish the two groups. Fall history and the IDA parameter of entropy were found to be significant risk factors for falls. This research proposed a new measure for the PCS robustness (1/MaxSens) and a new technique for quantifying the dynamical systems aspect of the PCS (IDA). These new PCS analysis techniques provide easy and effective ways to assess the PCS in occupational and clinical environments.
