Understanding the work of the city manager

The managerial behaviour approach to understanding managerial work has developed from research over the course of fifty years. The approach represents a marked departure from mainstream (and still prevalent) management approaches that depict management as a set of general composite functions. The managerial behaviour approach is distinctive in its empirical research background, object, focus and methodology. Its objective is to provide the simple answer to the complex question: what do managers do? However, the emphasis in the studies on managerial behaviour represents a limitation in so far as a context for locating and judging that behaviour is largely absent (Hales, 1986). This paper presents the results of initial research into managers operating in a different and largely neglected context - city councils. The research uses Mintzberg’s (1973) concept of behavioural roles as an analytical tool to explain and understand what city managers do. This study assesses whether these roles adequately capture the important features of managerial work in the city council. It is argued that while Mintzberg’s role framework is useful, structured observation alone does not adequately address the complexities of environments and styles of managers or the cognitive processes of managers. However, by integrating this approach with an appreciation of context and cognitive processes and how they can influence or affect managerial behaviour, we develop a more realistic description of what managers actually do and why they do it.

The treatment of landfill leachate using natural systems

Leachate may be defined as any liquid percolating through deposited waste and emitted from or contained within a landfill. If leachate migrates from a site it may pose a severe threat to the surrounding environment. Increasingly stringent environmental legislation both at European level and national level (Republic of Ireland) regarding the operation of landfill sites, control of associated emissions, as well as requirements for restoration and aftercare management (up to 30 years) has prompted research for this project into the design and development of a low cost, low maintenance, low technology trial system to treat landfill leachate at Kinsale Road Landfill Site, located on the outskirts of Cork city. A trial leachate treatment plant was constructed consisting of 14 separate treatment units (10 open top cylindrical cells [Ø 1.8 m x 2.0 high] and four reed beds [5.0m x 5.0m x 1.0m]) incorporating various alternative natural treatment processes including reed beds (vertical flow [VF] and horizontal flow [HF]), grass treatment planes, compost units, timber chip units, compost-timber chip units, stratified sand filters and willow treatment plots. High treatment efficiencies were achieved in units operating in sequence containing compost and timber chip media, vertical flow reed beds and grass treatment planes. Pollutant load removal rates of 99% for NH4, 84% for BOD5, 46% for COD, 63% for suspended solids, 94% for iron and 98% for manganese were recorded in the final effluent of successfully operated sequences at irrigation rates of 945 l/m2/day in the cylindrical cells and 96 l/m2/day in the VF reed beds and grass treatment planes. Almost total pathogen removal (E. coli) occurred in the final effluent of the same sequence. Denitrification rates of 37% were achieved for a limited period. A draft, up-scaled leachate treatment plant is presented, based on treatment performance of the trial plant.

An investigation into reactivity and selectivity in cycloadditions of 1,3-dipoles with formamidines

The objective of this research was to investigate the synthesis of nitrile oxides and to study their reactivity in 1,3-dipolar cycloadditions with formamidines. Chapter one looks at the literature surrounding the 1,3-dipolar cycloaddition reaction. It explores the generation of 1,3-dipoles (mainly nitrile oxides) and dipolarophiles (predominantly amidines). It discusses the potential synthetic uses of the 1,3-dipolar cycloadducts. It examines both and inter- and intra-molecular cycloaddition reactions. It recognises the use of the 1,3-dipolar cycloadditions as a successful method in building natural products and oxadiazolines. The decomposition of oxadiazolines as a route to nitriles is also outlined in this chapter. Chapter two discusses the results of this research candidate. The preparation of nitrile oxide precursors - hydroximoyl halides - is outlined at first. The generation of nitrile oxides is then demonstrated, followed by the preparation of furoxans. Methods for preparing the reference materials (nitriles and ureas), which result from decomposition of oxadiazolines, then follow. The preparation of series of Δ2-1,2,4- oxadiazolines via the 1,3-dipolar cycloaddition reaction is illustrated in this chapter. The selectivity of the addition of nitrile oxides to dipolarophiles was tested by competition reactions, which are also described in this chapter. NMR techniques were used in the study of the kinetics of the 1,3-dipolar cycloadditions used for the preparation of a series of Δ2-1,2,4-oxadiazolines, which is addressed in this chapter. Chapter three charts the experimental procedures followed to gain results which are discussed in chapter two. It also outlines all analytical data produced during the course of this research.

Within the carnal: re-reading Merleau-Ponty through the language of drawing

In order to present visual art as a paradigm for philosophy, Merleau-Ponty investigated the creative processes of artists whose work corresponded closely with his philosophical ideas. His essays on art are widely valued for emphasising process over product, and for challenging the primacy of the written word in all spheres of human expression. While it is clear that he initially favoured painting, Merleau-Ponty began to develop a much deeper understanding of the complexities of how art is made in his late work in parallel with his advancement of a new ontology. Although his ontology remains unfinished and only exists as working notes and a manuscript entitled The Visible and Invisible, Merleau-Ponty had begun to appreciate the fundamental role drawing plays in the making of art and the creation of a language of expression that is as vital as the written or spoken word. Through an examination of Merleau-Ponty’s unfinished manuscript and working notes my thesis will investigate his working methods and use of materials and also explore how he processed his ideas by using my own art practice as the basis of my research. This research will take the form of an inquiry into how the unfinished and incomplete nature of text and artworks, while they are still ‘works in progress’, can often reveal the more human and carnal components of creative processes. Applying my experience as a practitioner and a teacher in an art school, I focus on the significance of drawing practice for Merleau-Ponty’s later work, in order to rebalance an overemphasis on painting in the literature. Understanding the differences between these two art forms, and how they are taught, can offer an alternative engagement with Merleau-Ponty’s later work and his struggle to find a language to express his developing new ontology. In addition, by re-reading his work through the language of drawing, I believe we gain new insights which reaffirm Merleau-Ponty's relevance to contemporary art making and aesthetics.
