The Presumption of Innocence and Irish Criminal Law:Whittling the Golden Thread

The right to be presumed innocent until proven guilty has been described as the 'golden thread' running through the web of the English criminal law and a 'fundamental postulate' of Irish criminal law which enjoys constitutional protection. The purpose of this book is to consider whether the reality matches the rhetoris surrounding this central precept of our criminal law and to consider its efficacy in light of recent legislative innovations.

Enacting National Concerns: Accounts of the 2002 Golden Jubilee

Although the study of national identity in social psychology has examined the various ways in which the national group is ‘imagined’, little attention has been paid to the many collective national commemorations, celebrations and rituals of state assumed to unite the nation. This is surprising given the number of celebrations and commemorations which fill the calendars of modern nations
throughout the world and which are assumed by social scientists to play some part in the reproduction of the national community. Taking the British Royal Golden Jubilee celebrations of 2002, the present study examines how understandings of Anglo-British national identity are manifest in conversational
interviews during and after these events. In line with previous examinations of Anglo-Britishness, our respondents typically resisted imagining the national community as a homogenous whole and distanced themselves from depictions of the Jubilee as a nationalistic event. Support for the Jubilee was contingent upon the event being apolitical and inclusive.We suggest that such collective
national events could potentially facilitate ways of imagining the national community in terms of diversity and inclusivity rather than homogeneity and exclusivity.

Interpreting the near-infrared spectra of the 'golden standard' Type Ia supernova 2005cf

We present nine near-infrared (NIR) spectra of supernova (SN) 2005cf at epochs from -10 to +42d with respect to B-band maximum, complementing the existing excellent data sets available for this prototypical Type Ia SN at other wavelengths. The spectra show a time evolution and spectral features characteristic of normal Type Ia SNe, as illustrated by a comparison with SNe 1999ee, 2002bo and 2003du. The broad-band spectral energy distribution (SED) of SN 2005cf is studied in combined ultraviolet (UV), optical and NIR spectra at five epochs between ~8d before and ~10d after maximum light. We also present synthetic spectra of the hydrodynamic explosion model W7, which reproduce the key properties of SN 2005cf not only at UV-optical as previously reported, but also at NIR wavelengths. From the radiative-transfer calculations we infer that fluorescence is the driving mechanism that shapes the SED of SNe Ia. In particular, the NIR part of the spectrum is almost devoid of absorption features, and instead dominated by fluorescent emission of both iron-group material and intermediate-mass elements at pre-maximum epochs, and pure iron-group material after maximum light. A single P-Cygni feature of Mgii at early epochs and a series of relatively unblended Coii lines at late phases allow us to constrain the regions of the ejecta in which the respective elements are abundant. © 2012 The Authors Monthly Notices of the Royal Astronomical Society © 2012 RAS.

Role of Predalors, Habitat Attributes, and Spatial Autocorrelation on the Distribution of Eggs in the Northern Spectacled Salamander (Salamandrina perspicillata)

We predicted that the probability of egg occurrence of salamander Salamandrina perspicillata depended on stream features and predation by native crayfish Austropotamobius fulcisianus and the introduced trout Salmo trutta. We assessed the presence of S. perspicillata at 54 sites within a natural reserve of southern Tuscany, Italy. Generalized linear models with binomial errors were constructed using egg presence/absence and altitude, stream mean size and slope, electrical conductivity, water pH and temperature, and a predation factor, defined according to the presence/absence of crayfish and trout. Some competing models also included an autocovariate term, which estimated how much the response variable at any one sampling point reflected response values at surrounding points. The resulting models were compared using Akaike's information criterion. Model selection led to a subset of 14 models with Delta AIC(c) <7 (i.e., models ranging from substantial support to considerably less support), and all but one of these included an effect of predation. Models with the autocovariate term had considerably more support than those without the term. According to multimodel inference, the presence of trout and crayfish reduced the probability of egg occurrence from a mean level of 0.90 (SE limits: 0.98-0.55) to 0.12 (SE limits: 0.34-0.04). The presence of crayfish alone had no detectable effects (SE limits: 0.86-0.39). The results suggest that introduced trout have a detrimental effect on the reproductive output of S. perspicillata and confirm the fundamental importance of distinguishing the roles of endogenous and exogenous forces that act on population distribution.

Evidence for chronic morbillivirus infection in the Mediterranean striped dolphin (Stenella coeruleoalba)

In the summer of 1990 an epizootic infection caused by a morbillivirus (DMV) killed several thousand striped dolphins (Stenella coeruleoalba) in the Mediterranean Sea. In 1991 and 1992 the epizootic reached Italian and Greek waters. The infection by DMV in the acute period of the epizootic caused encephalitis, pneumonia and depletion of lymph nodes. After 1990, the systemic infection apparently disappeared from the Catalonian coast, giving way to cases of chronic infection of the CNS. Dolphins that died between 1991 and May 1994 were necropsied, and investigated for lesions due to DMV, and for the presence of morbillivirus antigen in tissues. Encephalitis occurred in 6 dolphins in which DMV antigen was demonstrated in the CNS and which were without lesions or antigen in other, non-nervous tissues. Inflammatory lesions, gliosis, and DMV antigen decreased in density and amount from cerebral grey matter, through the thalamic areas to the medulla oblongata. The cerebellum was usually spared. Lesions consisted of non-suppurative encephalitis, with diffuse gliosis and glial nodules and neuronophagia, and loss of neurons. Perivascular cuffing of lymphocytes and plasma cells was present in the cerebral cortex and the white matter beneath the cortex. Multinucleate syncytia were not detected in any of the dolphins. The haemagglutinin of DMV was detected mainly in neurons in the cerebral cortical areas. There was no clear relationship between the presence and amount of DMV antigen and the density or chronicity of lesions. Viral inclusions were seen in haematoxylin and eosin stained sections in 3/6 dolphins, principally in the nucleus and the cytoplasm of neurons. In the immunoperoxidase stained sections, dense granular deposits of chromogen, similar to viral inclusions, were evident in all 6 dolphins. The change in the distribution of lesions and of DMV antigen, from systemic to localized in the CNS, and the clustering of systemic DMV infections in the first four months of the epizootic, giving rise to sporadic occurrence of local CNS infection in the subsequent four years, as well as the chronic nature of the CNS lesions, which closely resembles subacute sclerosing panencephalitis, strongly support the existence of a chronic morbillivirus infection in the striped dolphin, as a delayed consequence of the 1990 epizootic.

Ranakinestatin-PPF from the Skin Secretion of the Fukien Gold-Striped Pond Frog, Pelophylax plancyi fukienensis: A Prototype of a Novel Class of Bradykinin B2 Receptor Antagonist Peptide from Ranid Frogs

The defensive skin secretions of many amphibians are a rich source of bradykinins and bradykinin-related peptides (BRPs). Members of this peptide group are also common components of reptile and arthropod venoms due to their multiple biological functions that include induction of pain, effects on many smooth muscle types, and lowering systemic blood pressure. While most BRPs are bradykinin receptor agonists, some have curiously been found to be exquisite antagonists, such as the maximakinin gene-related peptide, kinestatin—a specific bradykinin B₂-receptor antagonist from the skin of the giant fire-bellied toad, Bombina maxima. Here, we describe the identification, structural and functional characterization of a heptadecapeptide (DYTIRTRLHQGLSRKIV), named ranakinestatin-PPF, from the skin of the Chinese ranid frog, Pelophylax plancyi fukienensis, representing a prototype of a novel class of bradykinin B₂-receptor specific antagonist. Using a preconstricted preparation of rat tail arterial smooth muscle, a single dose of 10⁻⁶ M of the peptide effectively inhibited the dose-dependent relaxation effect of bradykinin between 10⁻¹¹ M and 10⁻⁵ M and subsequently, this effect was pharmacologically-characterized using specific bradykinin B₁- (desArg-HOE140) and B₂-receptor (HOE140) antagonists; the data from which demonstrated that the antagonism of the novel peptide was mediated through B₂-receptors. Ranakinestatin—PPF—thus represents a prototype of an amphibian skin peptide family that functions as a bradykinin B₂-receptor antagonist herein demonstrated using mammalian vascular smooth muscle.

Shortening design time through multiplatform simulations with a portable OpenCL golden-model: the LDPC decoder case

Hardware designers and engineers typically need to explore a multi-parametric design space in order to find the best configuration for their designs using simulations that can take weeks to months to complete. For example, designers of special purpose chips need to explore parameters such as the optimal bitwidth and data representation. This is the case for the development of complex algorithms such as Low-Density Parity-Check (LDPC) decoders used in modern communication systems. Currently, high-performance computing offers a wide set of acceleration options, that range from multicore CPUs to graphics processing units (GPUs) and FPGAs. Depending on the simulation requirements, the ideal architecture to use can vary. In this paper we propose a new design flow based on OpenCL, a unified multiplatform programming model, which accelerates LDPC decoding simulations, thereby significantly reducing architectural exploration and design time. OpenCL-based parallel kernels are used without modifications or code tuning on multicore CPUs, GPUs and FPGAs. We use SOpenCL (Silicon to OpenCL), a tool that automatically converts OpenCL kernels to RTL for mapping the simulations into FPGAs. To the best of our knowledge, this is the first time that a single, unmodified OpenCL code is used to target those three different platforms. We show that, depending on the design parameters to be explored in the simulation, on the dimension and phase of the design, the GPU or the FPGA may suit different purposes more conveniently, providing different acceleration factors. For example, although simulations can typically execute more than 3x faster on FPGAs than on GPUs, the overhead of circuit synthesis often outweighs the benefits of FPGA-accelerated execution.

Spatial variation in adult sex ratio across multiple scales in the invasive golden apple snail, Pomacea canaliculata

Adult sex ratio (ASR) has critical effects on behavior and life history and has implications for population demography, including the invasiveness of introduced species. ASR exhibits immense variation in nature, yet the scale dependence of this variation is rarely analyzed. In this study, using the generalized multilevel models, we investigated the variation in ASR across multiple nested spatial scales and analyzed the underlying causes for an invasive species, the golden apple snail Pomacea canaliculata. We partitioned the variance in ASR to describe the variations at different scales and then included the explanatory variables at the individual and group levels to analyze the potential causes driving the variation in ASR. We firstly determined there is a significant female-biased ASR for this species when accounting for the spatial and temporal autocorrelations of sampling. We found that, counter to nearly equal distributed variation at plot, habitat and region levels, ASR showed little variation at the town level. Temperature and precipitation at the region level were significantly positively associated with ASR, whereas the individual weight, the density characteristic, and sampling time were not significant factors influencing ASR. Our study suggests that offspring sex ratio of this species may shape the general pattern of ASR in the population level while the environmental variables at the region level translate the unbiased offspring sex ratio to the female-biased ASR. Future research should consider the implications of climate warming on the female-biased ASR of this invasive species and thus on invasion pattern.

The Golden Age? What the 100 Most Cited Articles in Terrorism Studies Tell Us

ln a context where widespread failings in the nature of terrorism research are well recognised - yet where the quantity of work is still enormous - is it possible to fairly assess whether the field is progressing or if it has become mired in mediocre research? Citation analysis is widely used to reveal the evolution and extent of progress in fields of study and to provide valuable insight into major trends and achievements. This study identifies and analyses the current 100 most cited journal articles in terrorism studies. A search was performed using Google Scholar for peer reviewed journal articles on subjects related to terrorism and counter-terrorism. The most cited papers were published across 62 journals which reflected the interdisciplinary nature of terrorism studies. Compared to other articles, the most cited papers were more likely to be the result of colloborative research and were also more likely to provide new data. 63 of the top 1-00 articles have been published since 2001. The findings are discussed in relation to the evolution of terrorism research and current debates on progress in the field.

Exploring the linguistic landscape: the case of the ‘Golden Triangle’ in the Algarve, Portugal

Studies of the linguistic landscape (LL) are concerned with language in its written form, in the public sphere; language that is visible to all through texts such as billboards and other public signs. The LL is such a taken-for-granted part of our everyday experience that its importance as a form of social practice is often overlooked. Taking a mixed methods approach to the case of the linguistic landscape of the ‘Golden Triangle’, an area of tourist resorts which is gradually becoming a residential area in the Algarve, Portugal, I suggest that the discursive construction of a place is partly achieved through the highly visible texts of the LL which may also impact upon the discursive construction of the collective identities of those who inhabit the place.
