The personality of “aggressive” and “non-aggressive” dog owners

The relationship between pet-keeping and owner personality has attracted considerable attention. Little focus, however, has been directed towards the personality of pet owners in relation to the type of pet owned. This study therefore explored the personality of pet owners in relation to the type of dog breed owned, focusing specifically on owners of breeds widely considered to be “aggressive” versus those more generally perceived as “non-aggressive”. One hundred and forty seven owners of “aggressive” (German shepherd dogs, Rottweilers) or “non-aggressive” (Labrador retrievers, Golden retrievers) dog breeds completed the Eysenck Personality Questionnaire short scale. Breed of dog owned was significantly related to owners’ psychoticism scores, with people who kept “aggressive” dogs having significantly higher scores on this trait than owners of “non-aggressive” dogs. Dog breed ownership was not significantly related to neuroticism, extraversion or lie scale scores, although male owners of “aggressive” dogs were found to be significantly less neurotic than women who kept “aggressive” or “non-aggressive” dogs. Overall, findings suggest that there is a significant relationship between dog breed ownership and specific personality traits, with owners of breeds widely considered to be “aggressive” harbouring more psychotic tendencies than people who choose to keep dogs with a reputedly less aggressive temperament.

Cigarette smoking and random serum cholesterol levels in a Northern Ireland general practice population of 18- to 20-year-old students and non-students

Coronary heart disease is the commonest cause of death in Northern Ireland, but few data exist on the incidence of risk factors in young adult students and non-students.

Components of Shame and Eating Disturbance among Clinical and Non-Clinical Populations

OBJECTIVE: To examine the association between components of shame (characterological, behavioural and bodily) and eating disturbance.

METHOD: This was a cross sectional study of 859 female and 256 male participants from the general population [non-clinical (NCP)] and 167 female participants from an eating disordered population [clinical (CP)] completing the Experience of Shame Scale. The NCP samples also completed the Eating Attitudes Test-26, and the CP samples completed the Eating Disorder Risk Composite of the Eating Disorder Inventory-3. Participants were recruited via schools/colleges, eating disorder charities and the Internet.

RESULTS: Bodily and characterological shame were independently predictive of eating disturbance in female NCP samples (both, p?<?.001); bodily shame was uniquely predictive of eating disturbance for the male NCP (p?<?.05) and female CP samples (p?<?.001).

CONCLUSION: The aetiology of eating disturbance may be different for male and female NCP samples. The male NCP and the female CP samples displayed a similar pathway to eating disturbance. It is important to acknowledge the different components of shame associated with eating disturbance in different populations.

Military Service Pensions for public and civil servants in independent Ireland

In 1924 the Cumann na nGaedheal government introduced the first Military Service Pensions Act to provide monetary compensation for those who fought for Irish independence between 1916 and 1923. Pensioners who were in receipt of remuneration from the state as civil and public servants had a portion of their pension deducted commensurate with their state income. This controversial provision was criticised by all political parties as representing a mean-spirited attitude towards veterans of the independence campaign and treating civil and public servants differently from those in private employment. It was eventually modified in the 1940s and abolished in the 1950s. This article provides a case study that highlights the parsimonious attitude of Irish governments towards veterans of the independence campaign and shows how the treatment of public and civil servants reflected tensions between the government and the civil service in the early years of the state.

Ciprofloxacin use and susceptibility of Gram-negative organisms to quinolone and non-quinolone antibiotics

A Trust strategy to reduce ciprofloxacin use was implemented at a University hospital. This study aimed to investigate whether the susceptibility of Gram-negative organisms (GNO) to alternative antimicrobials (co-amoxiclav, doxycycline, aztreonam, piperacillin/tazobactam, meropenem and gentamicin) changed, and whether there was any relationship between GNO susceptibility to these antimicrobials and ciprofloxacin usage.

Arsenic-speciation in arsenate-resistant and non-resistant populations of the earthworm, Lumbricus rubellus

Arsenic speciation was determined in Lumbricus rubellus Hoffmeister from arsenic-contaminated mine spoil sites and an uncontaminated site using HPLC-MS, HPLC-ICP-MS and XAS. It was previously demonstrated that L. rubellus from mine soils were more arsenate resistant than from the uncontaminated site and we wished to investigate if arsenic speciation had a role in this resistance. Earthworms from contaminated sites had considerably higher arsenic body burdens (maximum 1,358 mg As kg-1) compared to the uncontaminated site (maximum 13 mg As kg-1). The only organo-arsenic species found in methanol/water extracts for all earthworm populations was arsenobetaine, quantified using both HPLC-MS and HPLC-ICP-MS. Arsenobetaine concentrations were high in L. rubellus from the uncontaminated site when concentrations were expressed as a percentage of the total arsenic burden (23% mean), but earthworms from the contaminated sites with relatively low arsenic burdens also had these high levels of arsenobetaine (17% mean). As arsenic body burden increased, the percentage of arsenobetaine present decreased in a dose dependent manner, although its absolute concentration rose with increasing arsenic burden. The origin of this arsenobetaine is discussed. XAS analysis of arsenic mine L. rubellus showed that arsenic was primarily present as As(III) co-ordinated with sulfur (30% approx.), with some As(v) with oxygen (5%). Spectra for As(III) complexed with glutathione gave a very good fit to the spectra obtained for the earthworms, suggesting a role for sulfur co-ordination in arsenic metabolism at higher earthworm arsenic burdens. It is also possible that the disintegration of As(III)-S complexes may have taken place due to (a) processing of the sample, (b) storage of the extract or (c) HPLC anion exchange. HPLC-ICP-MS analysis of methanol extracts showed the presence of arsenite and arsenate, suggesting that these sulfur complexes disintegrate on extraction. The role of arsenic speciation in the resistance of L. rubellus to arsenate is considered.

Phagocytic and serum killing of capsulate and non-capsulate Bacteroides fragilis

The relative susceptibilities of capsulate and non- capsulate variants of Bacteroides fragilis to serum and phagocytic killing were investigated. The capsule of B. fragilis did not confer resistance to serum killing. Phagocytic killing of non- capsulate B. fragilis occurred at bacterial concentrations of 1 X 10(6) and 1 X 10(7) cfu/ml. Capsulate B. fragilis organisms were also phagocytosed and killed at a concentration of 1 X 10(6) cfu/ml, but phagocytosis and killing were impaired at a concentration of 1 X 10(7) cfu/ml.

Neonatal facial and cry responses to invasive and non-invasive procedures

Evaluation of pain in neonates is difficult due to their limited means of communication. The aim was to determine whether behavioural reactions of cry and facial activity provoked by an invasive procedure could be discriminated from responses to non-invasive tactile events. Thirty-six healthy full-term infants (mean age 2.2 h) received 3 procedures in counterbalanced order: intramuscular injection, application of triple dye to the umbilical stub, and rubbing thigh with alcohol. Significant effects of procedure were found for total face activity and latency to face movement. A cluster of facial actions comprised of brow bulging, eyes squeezed shut, deepening of the naso-labial furrow and open mouth was associated most frequently with the invasive procedure. Comparisons between the 2 non-invasive procedures showed more facial activity to thigh swabbing and least to application of triple dye to the umbilical cord. Acoustic analysis of cry showed statistically significant differences across procedures only for latency to cry and cry duration for the group as a whole. However, babies who cried to two procedures showed higher pitch and greater intensity to the injection. There were no significant differences in melody, dysphonation, or jitter. Methodological difficulties for investigators in this area were examined, including criteria for the selection of cries for analysis, and the logical and statistical challenges of contrasting cries induced by different conditions when some babies do not always cry. It was concluded that facial expression, in combination with short latency to onset of cry and long duration of first cry cycle typifies reaction to acute invasive procedures.
