Executive pay, tournaments and corporate performance in UK firms

Recent initiatives for modernising local government have ignored the potential contribution of parish and town councils. This article critically examines English parish and town councils in the context of the current debate about the need for government to be more responsive to community needs. It considers measures to enhance the capacity of these grassroots councils by recalibrating the responsibilities and resources between tiers of local government. It concludes by setting out possible reforms to facilitate the contribution of these local councils to the modernising agenda as both representatives of the community and potential providers of local services.

Remote sensing applied to land use and erosion hazard studies in Jamaica

The northern half of the parish of St. Catherine in Jamaica was selected as a test area to study, by means of remote sensing, the problems of soil erosion in a tropical environment. An initial study was carried out to determine whether eroded land within this environment could be successfully interpreted and mapped from the available 1: 25,000 scale aerial photographs. When satisfied that a sufficiently high percentage of the eroded land could be interpreted on the aerial photographs the main study was initiated. This involved interpreting the air photo cover of the study area for identifying and classifying land use and eroded land, and plotting the results on overlays on topographic base maps. These overlays were then composited with data on the soils and slopes of the study area. The areas of different soil type/slope/land use combinations were then measured, as was the area of eroded land for each of these combinations. This data was then analysed in two ways. The first way involved determining which of the combinations of soil type, slope and land use were most and least eroded and, on the basis of this, to draw up recommendations concerning future land use. The second analysis was aimed at determining which of the three factors, soil type, slope and land use, was most responsible for determining the rate of erosion. Although it was possible to show that slope was not very significant in determining the rate of erosion, it was much more difficult to separate the effects of land use and soil type. The results do, however, suggest that land use is more significant than soil type in determining the rate of erosion within the study area.

Molecular characterization of proteinaceous material in the Florida coastal Everglades

Dissolved organic nitrogen (DON) is the least known component of the nitrogen cycle, in part as a result of the lack of adequate analytical methods for its molecular characterization. In this study proteinaceous material in DON, collected at six geomorphologically different sites in the Florida coastal Everglades, was characterized by amino acid analysis and protein gel electrophoresis. The amino acid composition of the samples suggests that the canal DON was more degraded and subject to higher microbial inputs than the mangrove marshwater and marine end-member stations. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) results supported this observation as distinctly different protein profiles were obtained for the canal waters compared to samples collected at other stations. These preliminary results highlight the potential of combining amino acid and intact protein analysis to fingerprint the sources of DON in different aquatic environments, and show SDS-PAGE as a potentially useful method to characterize DON.

Chemical characteristics of dissolved organic matter in an oligotrophic subtropical wetland/estuarine ecosystem

Fluorescence properties of whole water samples and molecular characteristics of ultrafiltrated dissolved organic matter (UDOM > 1,000 D) such as lignin phenol and neutral sugar compositions and 13C nuclear magnetic resonance (NMR) spectra were determined along a freshwater to marine gradient in Everglades National Park. Furthermore, UDOM samples were categorized by hierarchical cluster analysis based on their pyrolysis gas chromatography/mass spectrometry products. Fluorescence properties suggest that autochthonous DOM leached/exuded from biomass is quantitatively important in this system. 13C NMR spectra showed that UDOM from the oligotrophic Taylor Slough (TS) and Florida Bay (FB) ecosystems has low aromatic C (13% ± 3% for TS; 2% ± 2% for FB) and very high O-alkyl C (54% ± 4% for TS; 75% ± 4% for FB) concentrations. High O-alkyl C concentrations in FB suggest seagrass/phytoplankton communities as dominant sources of UDOM. The amount of neutral sugars was not appreciably different between the TS and FB sites (115 ± 12 mg C g C-1 UDOM) but their concentrations suggest a low level of diagenesis and high production rates of this material in this oligotrophic environment. Total yield of lignin phenols (vanillyl + syringyl phenols) in TS was low (0.20–0.39 mg 100 mg C-1 UDOM) compared with other riverine environments and even lower in FB (0.04–0.07 mg 100 mg C-1 UDOM) and could be a result of photodegradation and/or dilution by other utochthonous DOM. The high O-alkyl and low aromatic nature of this UDOM suggests significant biogenic inputs (as compared with soils) and limited bioavailability in this ecosystem.

Chemical characterization of dissolved organic nitrogen in an oligotrophic subtropical coastal ecosystem

Water samples were collected from rivers and estuarine environments within the Florida Coastal Everglades (FCE) ecosystem, USA, and ultrafiltered dissolved organic matter (UDOM; 1 kDa) was isolated for characterization of its source, bioavailability and diagenetic state. A combination of techniques, including 15N cross-polarization magic angle spinning nuclear magnetic resonance (15N CPMAS NMR) and X-ray photoelectron spectroscopy (XPS), were used to analyze the N components of UDOM. The concentrations and compositions of total hydrolysable amino acids (HAAs) were analyzed to estimate UDOM bioavailability and diagenetic state. Optical properties (UV–visible and fluorescence) and the stable isotope ratios of C and N were measured to assess the source and dynamics of UDOM. Spectroscopic analyses consistently showed that the major N species of UDOM are in amide form, but significant contributions of aromatic-N were also observed. XPS showed a very high pyridinic-N concentration in the FCE–UDOM (21.7 ± 2.7%) compared with those in other environments. The sources of this aromatic-N are unclear, but could include soot and charred materials from wild fires. Relatively high total HAA concentrations (4 ± 2% UDOC or 27 ± 4% UDON) are indicative of bioavailable components, and HAA compositions suggest FCE–UDOM has not undergone extensive diagenetic processing. These observations can be attributed to the low microbial activity and a continuous supply of fresh UDOM in this oligotrophic ecosystem. Marsh plants appear to be the dominant source of UDOM in freshwater regions of the FCE, whereas seagrasses and algae are the dominant sources of UDOM in Florida Bay. This study demonstrates the utility of a multi-technique and multi-proxy approach to advance our understanding of DON biogeochemistry.

Spatial and Temporal Variability of Dissolved Organic Matter Quantity and Composition in an Oilgotrophic Subtropical Coastal Wetland

Dissolved organic matter (DOM) is an essential component of the carbon cycle and a critical driver in controlling variety of biogeochemical and ecological processes in wetlands. The quality of this DOM as it relates to composition and reactivity is directly related to its sources and may vary on temporal and spatial scales. However, large scale, long-term studies of DOM dynamics in wetlands are still scarce in the literature. Here we present a multi-year DOM characterization study for monthly surface water samples collected at 14 sampling stations along two transects within the greater Everglades, a subtropical, oligotrophic, coastal freshwater wetland-mangrove-estuarine ecosystem. In an attempt to assess quantitative and qualitative variations of DOM on both spatial and temporal scales, we determined dissolved organic carbon (DOC) values and DOM optical properties, respectively. DOM quality was assessed using, excitation emission matrix (EEM) fluorescence coupled with parallel factor analysis (PARAFAC). Variations of the PARAFAC components abundance and composition were clearly observed on spatial and seasonal scales. Dry versus wet season DOC concentrations were affected by dry-down and re-wetting processes in the freshwater marshes, while DOM compositional features were controlled by soil and higher plant versus periphyton sources respectively. Peat-soil based freshwater marsh sites could be clearly differentiated from marl-soil based sites based on EEM–PARAFAC data. Freshwater marsh DOM was enriched in higher plant and soil-derived humic-like compounds, compared to estuarine sites which were more controlled by algae- and microbial-derived inputs. DOM from fringe mangrove sites could be differentiated between tidally influenced sites and sites exposed to long inundation periods. As such coastal estuarine sites were significantly controlled by hydrology, while DOM dynamics in Florida Bay were seasonally driven by both primary productivity and hydrology. This study exemplifies the application of long term optical properties monitoring as an effective technique to investigate DOM dynamics in aquatic ecosystems. The work presented here also serves as a pre-restoration condition dataset for DOM in the context of the Comprehensive Everglades Restoration Plan (CERP).

"Porta do Céu": o processo de cristianização da Freguesia de Nossa Senhora da Apresentação (1681-1714)

This study aims to analyze the process of Christianization space in the different areas of the Parish of Our lady of Presentation between 1681 and 1714. To accomplish this goal, the main primary sources researched was the parish records of baptism. Thus, areas of the parish were designed based on two fundamental concepts: Christianization of the locations (and souls), based on the study of Claudia Damasceno, who worked with the notion of ecclesiastical circumscription, adapted for the case of Parish of Our lady of Presentation, and the concept of local experimentation, by Yi-Fu Tuan. Christianization the areas was the process of transformation of spatial logic, found previously by the Portuguese, by overlapping the ecclesiastical logic over Indigenous perception, through buildings construction, to initiate people to Catholicism. The experiment, in turn, would be made by the local residents studied and by religious themselves, making these areas, in places, in the sense of achieving new local meanings. It was verified, therefore, that Parish of Our lady of Presentation had at least three distinct places, the City of Natal, the villages around and the parish missions. Then, the focus of this thesis is to analyze how settlers used these different places as religious meanings.

En el pasado colonial y en el presente revolucionario : los curas párrocos y las parroquias como soportes del cambio político

El período de descomposición del orden colonial y de trabajosa construcción de otro nuevo en clave republicana reconoce un conjunto de dispositivos y prácticas que posibilitaron el cambio político. Determinadas instituciones y agentes soportaron esta transición que supuso desmontar muchas de las antiguas referencias y modelos de acción política, y orientaron la emergencia de nuevas formas de concebir, percibir y relacionarse con el poder. En la persistencia de algunas de estas figuras clave residió la factibilidad de las nuevas repúblicas. En particular, los agentes y las jurisdicciones eclesiásticos, los ritos y celebraciones religiosas permanecieron ocupando un lugar que no puede ignorarse.

The Provenance and Geochemical Alteration of Bermudan Eolianites

Large calcareous eolianites cover the remote island of Bermuda, accounting for more than 90% of the limestone bedrock. This study examines the sedimentology and geochemistry of these eolianites to better understand Pleistocene oceanography and the meteoric alteration of subtropical carbonate sediments. Cluster analyses reveal that the eolian carbonate sediments fall into two natural groups that represent lagoonal and reefal end members of marine sediment production. Coral fragments are uncharacteristically absent, possibly destroyed prior to their incorporation into eolian deposits by endolithic microboring organisms or broken up during transport. Sediment assemblages lead to the following interpretations of the Bermudan offshore environment: (1) the Ledge Flats reef system along the southwestern coast has been active since MIS 11, contributing coralline algal-rich sediment to the northern beaches of Sandy’s Parish and acting as an energy barrier in the south, allowing for low energy sedimentation in the quiet back- reef region; (2) on the northeastern coast, the low energy back-reef region landward of the Ledge Flats has thrived since MIS 11; (3) during MIS 5e, slightly warmer water temperatures led to the hindrance of coralline algal growth along the southern coast and in the North Lagoon. These are the first interpretations of Pleistocene marine assemblages on Bermuda. Meteoric fluids progressively transformed the pristine carbonate sediments into hardened limestones in a predictable solubility-dependent manner. The progressive alteration is coincident with: (1) divergence of δ18O and δ13C values from those similar to unaltered sediment towards those of calcrete, due to interaction with CO2-charged meteoric fluids; (2) depletion of elements with low partitioning coefficients and low meteoric concentrations, such as barium, boron, magnesium, potassium, sodium, strontium, and uranium; (3) enrichment of iron from Terra Rossa-hosted iron oxides; (4) enrichment of aluminum via detrital minerals sourced from protosol horizons; and (5) manganese concentrations that remain uncharacteristically low, owing to the lack of a consistent manganese source. Elemental correlations are useful for characterizing meteoric diagenesis, assuming the primary mineralogy is recognized, all components have been fully altered, and inter-particle cements are ubiquitous.

Faith on the Home Front: Aspects of Church Life and Popular Religion in Birmingham, 1939-1945

The nature of religion on the domestic front in Britain during the Second World War has, hitherto, been relatively unexplored. This study focuses on Birmingham and describes wartime popular religion, primarily as recounted in oral testimony. The difference the War made to people’s faith, and the consolation wrought by prayer and a religious outlook are explored, as are the religious language and concepts utilised by the wartime popular media of cinema and wireless. Clerical rhetoric about the War and concerns to spiritualise the war effort are dealt with by an analysis of locally published sources, especially parish magazines and other religious ephemera, which set the War on the spiritual as much as the military plane. A final section of the study is devoted to measuring the extent of the influence of the churches in the creation of a vision for post-war Britain and Birmingham.

Evaluation of vegetation recovery after fire: a case study in Calde, central region of Portugal

Remote Sensing has been used for decades, and more and more applications are added to its repertoire. With this study we aim to show the use of Remote Sensing in the field of vegetation recovery monitoring in burned areas and the added value of data with a high spatial resolution. This was done by analysing both Landsat 7 and 8 scenes, after the forest fire of summer 2012 in the parish of Calde, in the central region of Portugal, as well as an orthophoto produced with images acquired by an unmanned aerial vehicle.
