An examination of Graham Fitkin’s saxophone music and implications for the modern saxophonist

There is a significant body of academic writing on long-entrenched traditional chamber repertoire for the saxophone, both in the form of creative outputs (saxophone repertoire and études) and traditional academic writing (practical methods, journal articles, and dissertations). In contrast, the aggregate research output existing on “contemporary-classical” music for the saxophone is comparatively small. This research endeavours to contribute to the lesser-studied field, by providing an exposition on saxophone usage in the works of Graham Fitkin (1963-), an internationally recognised composer known for his music which demonstrates a variety of more recent styles, including post-minimalism, jazz and heavy influence from popular music. The study explores Graham Fitkin’s artistic process or processes and the construction of his pieces, the reasons for his use of saxophones in his music, what his usage of saxophones entails from a technical perspective, and examples of such factors in three selected works. The study employs a qualitative research methodology incorporating literature review, a semi-structured interview with Graham Fitkin, and supplemental compositional analysis of three works (Stub, Hard Fairy, and Torn Edge). The research identified three key approaches that Fitkin employs in composing his music and discusses these approaches in the context of three saxophone works, exploring related techniques, considerations, and effects. This research is intended to aid saxophonists in their study, interpretation, and performance of Fitkin’s saxophone works, by bringing to light aspects of musical design and Fitkin’s use of saxophones to achieve them

Juvenile crime stories use police blotter without comment from suspects

This article discusses a research on news media coverage of juvenile crime. It seeks to answer two questions: what sources do present-day reporters rely on in writing juvenile justice stories; and, are reporters more likely to balance police and defendants comments. The study focused on stories published in Connecticut\u27s three largest newspapers--the Hartford Courant, the New Haven Register, and the Connecticut Post--between January 1, 2002, and March 31, 2002. The study\u27s design was based on a census of all newspaper stories, not a random sample, in the three-month period. The methodology yielded 180 news stories, those generated by both the staff and six Associated Press stories. Results suggest that, at least in the newspapers studied here, not much has changed since Doris Graber first documented the shortcomings of crime reporting more than two decades ago in her book, Crime News and the Public. The economic efficiency that allows reporters to chum out stories with little effort from the police blotter has not changed. Coverage of juvenile crime issues followed the same pattern

Hexagonal uniformly redundant arrays (HURAs) for scintillator based coded aperture neutron imaging

A series of Monte Carlo simulations have been conducted, making use of the EJ-426 neutron scintillator detector, to investigate the potential of using hexagonal uniformly redundant arrays (HURAs) for scintillator based coded aperture neutron imaging. This type of scintillator material has a low sensitivity to gamma rays, therefore, is of particular use in a system with a source that emits both neutrons and gamma rays. The simulations used an AmBe source, neutron images have been produced using different coded-aperture materials (boron-10, cadmium-113 and gadolinium-157) and location error has also been estimated. In each case the neutron image clearly shows the location of the source with a relatively small location error. Neutron images with high resolution can be easily used to identify and locate nuclear materials precisely in nuclear security and nuclear decommissioning applications

Comment on 'The Value of Cost Benefit Analysis of Road Projects'. Quarterly Economic Commentary Special Article, April 1985

In accepting the invitation by the editors of the Quarterly Economic Commentary to comment on Mr. Mansergh's paper it is hoped to show that his fears about cost benefit analysis and its use are unjustified. His paper proposes two important changes in cost benefit analysis. These are the treatment of labour costs as benefits and taxes as a resource rather than as a transfer payment. Labour is treated as a cost in cost benefit .. analysis because the supply price of labour is positve. Workers require a positive sum in exchange for their labour. Cost benefit analysis measures the benefits and costs to society as a whole from projects. The level of a project's benefits over its costs is the critical factor in evaluating the project. The division of the benefits between those accruing in tax revenues and elsewhere in the economy distributes the net benefits of the project. It neither increases nor reduces the level of net benefits from the, project. Transfer payments, such as taxes, are therefore excluded from cost benefit analysis. The proposed changes add two categories of benefit, labour costs and tax revenues, and delete one cost, labour. These changes would raise the rate of return on projects now rejected. They are thus inconsistent with the paper's recommendation that "a more rational result might be a reduction in the national enthusiasm for investment"..

The challenges, uncertainties and opportunities of bioaerosol dispersion modelling from open composting facilities

Bioaerosols are ubiquitous organic particles that comprise viruses, bacteria and coarser fractions of organic matter. Known to adversely affect human health, the impact of bioaerosols on a population often manifests as outbreaks of illnesses such as Legionnaires Disease and Q fever, although the concentrations and environmental conditions in which these impacts occur are not well understood. Bioaerosol concentrations vary from source to source, but specific human activities such as water treatment, intensive agriculture and composting facilitate the generation of bioaerosol concentrations many times higher than natural background levels. Bioaerosols are not considered ‘traditional’ pollutants in the same way as PM10, PM2.5, and gases such as NO2, and consequently dispersion models do not include a bespoke method for their assessment. As identified in previous studies, priority areas for improving the robustness of these dispersion models include: 1) the development of bespoke monitoring studies designed to generate accurate modelling input data; 2) the publication of a robust emissions inventory; 3) a code of practice to provide guidelines for consistent bioaerosol modelling practices; and 4) a greater understanding of background bioaerosol emissions. The aim of this research project, funded by the Natural Environmental Research Council (NERC), is to address these key areas through a better understanding of the generation, concentration and potential dispersion of bioaerosols from intensive agricultural and biowaste facilities, using case studies developed at specific locations within the UK. The objective is to further refine existing bioaerosol monitoring and modelling guidelines to provide a more robust framework for regulating authorities and site operators. This contribution outlines the gaps that hinder robust dispersion modelling, and describes the on-site bioaerosol data collection methods used in the study, explaining how they might be used to close these gaps. Examples of bioaerosol dispersion modelled using ADMS 5 are presented and discussed

The Universe is at Most 88% Neutral at z=10.6

Recent observations of GN-z11 with JWST have revealed a Ly$\alpha$ emission line with an equivalent width of 18$\pm 2$ angstroms. At z=10.6, this galaxy is expected to lie in the heart of reionization. We use a series of inhomogeneous reionization simulations to derive the distribution of the Ly$\alpha$ EW after traveling through the neutral intergalactic medium with varying average neutral gas fraction, $x_{HI}$. We use these distribution to place an upper limit of $x_{HI} <$ 0.88 at z=10.6 at 95% confidence level. We compare our upper limit to different reionization history models, which include the recently identified enhancement at the bright end of the luminosity function at z>8. We find that models in which faint galaxies have higher escape fraction compared to bright galaxies are favored by the new data.Comment: 7 pages, 3 figure

Towards improved bioaerosol model validation and verification

Bioaerosols, comprised of bacteria, fungi and viruses are ubiquitous in ambient air. Known to adversely affect human health, the impact of bioaerosols on a population often manifests as outbreaks of illnesses such as Legionnaires Disease and Q fever, although the concentrations and environmental conditions in which these impacts occur are not well understood. Bioaerosol concentrations vary from source to source, but specific industrialised human activities such as water treatment, intensive agriculture and open windrow composting facilitate the generation of bioaerosol concentrations many times higher than natural background levels. Bioaerosol sampling is currently undertaken according to the requirements of the Environment Agency’s regulatory framework, in which the collection of bioaerosols and not its long-term measurement is of most importance. As a consequence, sampling devices are often moved around site according to changing wind direction and sampling intervals are invariably short-term. The dispersion modelling of bioaerosols from composting facilities typically relies on proxy pollutant parameters. In addition, the use of short term emission data gathering strategies in which monitors are moved frequently with wind direction, do not provide a robust reliable and repeatable dataset by which to validate any modelling or to verify its performance. New sampling methods such as the Spectral Intensity Bioaerosol Sensor (SIBS) provide an opportunity to address several gaps in bioaerosol model validation and verification. In the context of model validation, this paper sets out the current weaknesses in bioaerosol monitoring from the perspective of robust modelling requirements

Isotopic exchange of carbon-bound hydrogen over geologic timescales

The increasing popularity of compound-specific hydrogen isotope (D/H) analyses for investigating sedimentary organic matter raises numerous questions about the exchange of carbon-bound hydrogen over geologic timescales. Important questions include the rates of isotopic exchange, methods for diagnosing exchange in ancient samples, and the isotopic consequences of that exchange. This article provides a review of relevant literature data along with new data from several pilot studies to investigate such issues. Published experimental estimates of exchange rates between organic hydrogen and water indicate that at warm temperatures (50–100°C) exchange likely occurs on timescales of 10^4 to 10^8 yr. Incubation experiments using organic compounds and D-enriched water, combined with compound-specific D/H analyses, provide a new and highly sensitive method for measuring exchange at low temperatures. Comparison of δD values for isoprenoid and n-alkyl carbon skeletons in sedimentary organic matter provides no evidence for exchange in young (350 Ma) rocks. Specific rates of exchange are probably influenced by the nature and abundance of organic matter, pore-water chemistry, the presence of catalytic mineral surfaces, and perhaps even enzymatic activity. Estimates of equilibrium fractionation factors between organic H and water indicate that typical lipids will be depleted in D relative to water by ∼75 to 140‰ at equilibrium (30°C). Thus large differences in δD between organic molecules and water cannot be unambiguously interpreted as evidence against hydrogen exchange. A better approach may be to use changes in stereochemistry as a proxy for hydrogen exchange. For example, estimated rates of H exchange in pristane are similar to predicted rates for stereochemical inversion in steranes and hopanes. The isotopic consequences of this exchange remain in question. Incubations of cholestene with D_2O indicate that the number of D atoms incorporated during structural rearrangements can be far less than the number of C-H bonds that are broken. Sample calculations indicate that, for steranes in immature sediments, the D/H ratio imparted by biosynthesis may be largely preserved in spite of significant structural changes

Child Custody Outcomes in Cases Involving Parental Alienation and Abuse Allegations

Arguably the most troubling aspect of justice system response to intimate partner violence is custody courts\u27 failure to protect children when mothers allege the father is abusive. Family courts\u27 errors in assessing adult and child abuse, and punitive responses to abuse allegations, have been widely documented. A significant contributor to these errors is the pseudo-scientific theory of parental alienation (PA). Originally termed parental alienation syndrome (PAS), the theory suggests that when mothers allege that a child is not safe with the father, they are doing so illegitimately, to alienate the child from the father. PA labeling often results in dismissal of women\u27s and children\u27s reports of abuse, and sometimes trumps even expert child abuse evaluations. PAS was explicitly based on negative stereotypes of mothers and has been widely discredited. The term parental alienation – while treated as distinct - is still widely used in ways that are virtually identical to PAS. Nonetheless, because PA is nominally gender neutral (and not called a scientific syndrome), it continues to have substantial credibility in court. The first goal of this project was to ascertain whether empirical evidence indicates that parental alienation is, like PAS, gender-biased in practice and outcome. Second, the study sought to explore outcomes in custody/abuse litigation by gender and by differing types of abuse. Analysis of over 2000 court opinions confirms that courts are skeptical of mothers’ claims of abuse by fathers; this skepticism is greatest when mothers claim child abuse. The findings also confirm that fathers’ cross-claims of parental alienation increase (virtually doubling) courts’ rejection of mothers’ abuse claims, and mothers’ losses of custody to the father accused of abuse. In comparing court responses when fathers accuse mothers of abuse, a significant gender difference is identified. Finally, the findings indicate that where Guardians Ad Litem or custody evaluators are appointed, unfavorable outcomes for mothers and gender differences are increased. The study relies solely on electronically available published opinions in child custody cases. It has produced an invaluable database identifying 10 years of published cases involving alienation, abuse and custody, while coding parties’ claims and defenses, outcomes, and other key factors by gender and parental status
