Animal abuse and intimate partner violence: researching the link and its significance in Ireland - a veterinary perspective
B Gallagher, M Allen, B Jones
Irish Veterinary Journal , 2008, DOI: 10.1186/2046-0481-61-10-658
Abstract: A number of recent studies have highlighted the relationship between non-accidental injury (NAI) in animals (also known as 'battered pet syndrome') and domestic violence [20,3,6,15]. Further research identifies that intimate partner violence, abuse of children and abuse of companion pets tends to occur in the same families ([9,1,2]; Boat, 1995; [6,15,14]). Flynn [15] found that 46.5% of women using a refuge in South Carolina reported that their abuser had either harmed or threatened to harm their pets. Other studies have suggested a higher prevalence. Ascione [5] demonstrated that almost two-thirds of women who suffered domestic violence also witnessed abuse of, or threats to, their pets. A study in the United Kingdom identified similar statistics, with 66% of women in one survey reporting threats, and 38% reporting actual abuse of their pet [26]. This data indicates that animal abuse in the context of interpersonal violence is likely to be more prevalent and universal than was previously realised. While it is likely that similar patterns of multiple forms of abuse can be found in Ireland, no Irish study has examined this aspect of intimate partner violence.The purpose of this study, undertaken by veterinary practitioners and a social worker, was to examine the 'link' between domestic violence and animal abuse in Ireland, and to establish to what extent the abuse of pets is used to control women within an abusive relationship. In doing so, the aim is to raise awareness of the 'link' amongst the staff of women's refuges, social workers, childcare workers and veterinary practitioners.Official Irish statistics place reports of violence against women within European and US figures, with the only Irish national prevalence study to-date [19] showing that 18% of women had, at some time in their lives, been victims of emotional, sexual or physical violence, or subject to threats of violence, and had their property or pets damaged, by male intimate partners.

A Selective Emotional Decision-Making Bias Elicited by Facial Expressions
Nicholas Furl, Shannon Gallagher, Bruno B. Averbeck
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0033461
Abstract: Emotional and social information can sway otherwise rational decisions. For example, when participants decide between two faces that are probabilistically rewarded, they make biased choices that favor smiling relative to angry faces. This bias may arise because facial expressions evoke positive and negative emotional responses, which in turn may motivate social approach and avoidance. We tested a wide range of pictures that evoke emotions or convey social information, including animals, words, foods, a variety of scenes, and faces differing in trustworthiness or attractiveness, but we found only facial expressions biased decisions. Our results extend brain imaging and pharmacological findings, which suggest that a brain mechanism supporting social interaction may be involved. Facial expressions appear to exert special influence over this social interaction mechanism, one capable of biasing otherwise rational choices. These results illustrate that only specific types of emotional experiences can best sway our choices.
(Ga,Mn)As based superlattices and the search for antiferromagnetic interlayer coupling
A. D. Giddings,T. Jungwirth,B. L. Gallagher
Physics , 2008, DOI: 10.1103/PhysRevB.78.165312
Abstract: Antiferromagnetic interlayer coupling in dilute magnetic semiconductor superlattices could result in the realisation of large magnetoresistance effects analogous to the giant magnetoresistance seen in metallic multilayer structures. In this paper we use a mean-field theory of carrier induced ferromagnetism to explore the multidimensional parameter space available in (Ga,Mn)As based superlattice systems. Based on these investigations we examine the feasibility of creating a superlattice that exhibits antiferromagnetic coupling and suggest potentially viable recipes.
Emission Line Ratios and Variations in Temperature and Ionization State in the Diffuse Ionized Gas of Five Edge-on Galaxies
B. Otte,J. S. Gallagher III,R. J. Reynolds
Physics , 2002, DOI: 10.1086/340381
Abstract: We present spectroscopic observations of ionized gas in the disk-halo regions of five edge-on galaxies, covering a wavelength range from [OII] 3727A to [SII] 6716.4A. The inclusion of the [OII] emission provides additional constraints on the properties of the diffuse ionized gas (DIG), in particular, the origin of the observed spatial variations in the line intensity ratios. We have derived electron temperatures, ionization fractions and abundances along the slit. Our data include both slit positions parallel and perpendicular to the galactic disks. This allowed us to examine variations in the line intensity ratios with height above the midplane as well as distance from the galactic centers. The observed increase in the [OII]/Halpha line ratio towards the halo seems to require an increase in electron temperature caused by a non-ionizing heating mechanism. We conclude that gradients in the electron temperature can play a significant role in the observed variations in the optical emission line ratios from extraplanar DIG.
Interlayer exchange coupling in (Ga,Mn)As based multilayers
A. D. Giddings,T. Jungwirth,B. L. Gallagher
Statistics , 2006, DOI: 10.1002/pssc.200672834
Abstract: Exhibiting antiferromagnetic interlayer coupling in dilute magnetic semiconductor multilayers is essential for the realisation of magnetoresistances analogous to giant magnetoresistance in metallic multilayer structures. In this work we use a mean-field theory of carrier induced ferromagnetism to explore possible (Ga,Mn)As based multilayer structures that might yield antiferromagnetic coupling.
Analysis on the Growth Rhythm and Cold Tolerance of Five-Year Old Eucalyptus benthamii Plantation for Bioenergy  [PDF]
Aihua Yu, Tom Gallagher
Open Journal of Forestry (OJF) , 2015, DOI: 10.4236/ojf.2015.56052
Abstract: A research plot of Eucalyptus benthamii was planted to evaluate this species’ ability to supply the emerging bioenergy markets that are developing in the southern U.S. The plot was planted in two different densities to investigate the growth parameters and the cold tolerance. The stand was measured annually through five growing seasons. The results indicated that the growth difference among the young E. benthamii was noticeable. For example, the maximum and minimum value of five-year old trees at diameter breast height (DBH) was 27.9 centimeters and 1.27 centimeters; and the maximum and minimum value of tree height was 22.86 meters and 2.44 meters, respectively. The yearly change in DBH and height of E. benthamii had significant differences. The average annual survival rates of E. benthamii had differences under the two planting densities (1650 trees ha-1 and 1237 trees ha-1). The densities also had effects on the height and DBH growth of E. benthamii. The average DBH and height of 1650 trees ha-1 plantation were 11.18 centimeters and 15.03 meters, and the average DBH and height of 1237 trees ha-1 plantation were 13.46 centimeters and 16.28 meters. The volume per hectare of 1650 trees ha-1 and 1237 trees ha-1 plantation were 111.45 cubic meters and 101.15 cubic meters, respectively. Average diameter growth was almost 2.54 centimeters per year and average height growth was over 3 meters. E. benthamii plantations were considered tolerant to -7.4 degrees Celsius and a cold spell during early 2014 (-11.3 degrees Celsius for two consecutive nights) killed the plantation. The growth of E. benthamii also
Dissociation of the N400 component between linguistic and non-linguistic processing: A source analysis study  [PDF]
Anne Gallagher, Renée Béland, Phetsamone Vannasing, Maria Luisa Bringas, Pedro Valdes Sosa, Nelson J. Trujillo-Barreto, John Connolly, Maryse Lassonde
World Journal of Neuroscience (WJNS) , 2014, DOI: 10.4236/wjns.2014.41004
Abstract:


The N400 component is commonly associated with the detection of linguistic incongruity. A few studies have shown that the N400 can also be elicited by non-linguistic stimuli. Different spatiotemporal patterns were observed between the typical Linguistic N400 and the Non-linguistic N400, suggesting distinct brain generators. The aim of this study was to investigate the presence of an N400 in response to linguistic and non-linguistic stimuli, and to specify anatomical sources of both N400s using a novel analysis method: the Bayesian Model Averaging (BMA) distributed source model. Picture-word and environmental soundpicture associations, either congruent or incongruent, were presented to ten young healthy adults while highdensity ERP recordings were made. Standard electrophysiological analyses confirmed that the N400 was not specific to linguistic incongruity but was also elicited by environmental sound-picture incongruities. Different topographic distributions were obtained for the Linguistic N400 and Non-linguistic N400. BMA analysis showed that the Linguistic N400 generators were mostly located in the left superior temporal gyrus, whereas the sources of the Non-linguistic N400 were identified mostly in the right middle and superior temporal gyri. Detection of linguistic incongruities recruited cerebral areas commonly associated with language processing, whereas non-linguistic incongruities recruited right cerebral regions usually associated with auditory processing of non-linguistic stimuli. The Linguistic and Non-linguistic N400s appear to be elicited by similar cognitive mechanisms assumed by different cerebral areas depending on the type of material to be processed. The present findings support the existence of parallel pathways for the processing of linguistic and non-linguistic incongruities.


Greater lean tissue and skeletal muscle mass are associated with higher bone mineral content in children

Nutrition & Metabolism , 2010, DOI: 10.1186/1743-7075-7-41
Abstract: 175 healthy children (103 boys; 72 girls) had assessments of body mass, height, and Tanner stage. Whole body bone mineral content, non-bone lean body mass (nbLBM), skeletal muscle mass, and fat mass were assessed using dual-energy X-ray absorptiometry (DXA). Muscle mass was estimated from an equation using appendicular lean soft tissue measured by DXA, weight and height. Estimates of skeletal muscle mass and adipose tissue were also assessed by whole body multi-slice magnetic resonance imaging (MRI). Linear regression was used to determine whether skeletal muscle mass assessed by DXA or by MRI were better predictors of bone mineral content compared with nbLBM after adjusting for sex, age, race or ethnicity, and Tanner stage.Greater skeletal muscle mass was associated with greater bone mineral content (p < 0.001). The skeletal muscle mass assessed by MRI provided a better fitting regression model (determined by R2 statistic) compared with assessment by DXA for predicting bone mineral content. The proportion of skeletal muscle mass in nbLBM was significantly associated with greater bone mineral content adjusted for total nbLBM.This study is among the first to describe and compare the relationship of skeletal muscle to bone using both MRI and DXA estimates. The results demonstrate that the use of MRI provides a modestly better fitting model for the relationship of skeletal muscle to bone compared with DXA. Skeletal muscle had an impact on bone mineral content independent of total non-bone lean body mass. In addition, Hispanics had greater bone mineral content compared to other race and ethnic groups after adjusting for sex, age, adipose tissue, skeletal muscle mass, and height.Fat-free body mass as measured by dual X-ray absorptiometry (DXA) consists of 50% bone and extracellular fluids, and 50% non-bone lean body mass (nbLBM) including muscle, organs, and connective tissue[1]. In a 1992 review of human studies, Weinsier et al. reported that as children grow bone is co
Linking aerosol fluxes in street canyons to urban city-scale emissions

Atmospheric Chemistry and Physics Discussions , 2009,
Abstract: In this study we investigate ultrafine particle (UFP) fluxes using a first order eddy viscosity turbulence closure Computational Fluid Dynamics (CFD) model and determine the different factors that influence emissions of UFP into the urban boundary layer. Both vertical turbulent fluxes as well as the fluxes due to mean flow are shown to contribute to the overall ventilation characteristics of street canyons. We then derive a simple parameterised numerical prediction model for canyon top UFP venting which is then compared with tower based micrometeorological flux measurements obtained during the REPARTEE and CityFlux field experiments.
