A Strategy for Dog-Owner Education

The author comments on the large number of animals being euthanized in shelters and suggests that dog owners undertake an education program before acquiring a dog as a pet. The author acknowledges to difficulties involved in such a change and recommends procedures to address them

A Strategy for Dog-Owner Education

The author responds to an article by Graham Henderson of the Toronto Humane Society (lJSAP 2(6):305-309, 1981) commenting on his proposal regarding the education of dog owners. He agreed with many of Henderson\u27s statements and was pleased that Henderson, in turn, agreed with most of the author\u27s points. However, he notes that he found Mr. Henderson\u27s article to contain several inaccuracies and contradictions addressed here. The author recaps his proposed program of Dog Owner Education and reemphasizes some of its major points. The primary intention is to promote an early license application: preferably before the owner acquires a dog, but at least while the dog is still a puppy. The rationale behind this suggestion is that this would provide the ideal opportunity to give the prospective (or new) dog owner an information package on health, husbandry, puppy training, and the prevention of behavioral problems (of which aggression is the most common and the most serious). Spreading the burden of licensing control is a secondary aim. In addition, the author recommends that the fee for the license should not be a deterrent to dog ownership. The author then expands on some proposals to develop suitable education materials for new dog owners

A Strategy for Dog-Owner Education (Response)

I have read with interest the response by Graham Henderson of the Toronto Humane Society (lnt J Stud Anim Prob 2(6):305-309, 1981). I agree with many of his statements and am pleased that he, in turn, agreed with most of mine, although at first, this was not entirely apparent. In fact, I found Mr. Henderson\u27s letter to be somewhat confusing, and it contained a number of inaccuracies and contradictions. So, please bear with me if I go into some detail to try to unravel the confusion

Consolidated democracies and the past: transitional justice in Spain and Canada

The majority of scholarly consideration on the principles of transitional justice has focused upon how emerging democracies should deal with former regimes immediately following violent conflict. However, consolidated democracies have also begun to turn to transitional justice mechanisms in order to address historical legacies of violence and repression. This article examines Spain and Canada, two countries dealing with seemingly disparate issues: the legacy of the Civil War and Franco’s repressive regime, and the abuses of the Indian Residential Schools system, respectively. However, both nations have been forced to respond to similar questions regarding the merits of revisiting a painful past well after democratic consolidation. The article first discusses the proliferation of transitional justice principles into consolidated democracies, and considers the argument that such processes may destabilize and divide society, particularly by exacerbating federalist divisions. It concludes that despite the unique challenges of employing transitional justice so long after a transition, the Spanish and Canadian cases reveal the inevitability of confronting the past in response to charges of hypocrisy and illegitimacy. Consolidated democracies, embedded with principles of public contention and debate, are well-suited to respond to these challenges while maintaining political and societal cohesion

New money for mental health : will it make things better for rural and remote Australia?

New Australian government funding for the Better Outcomes in Mental Health Care initiative is a significant step forward for mental health, with general practitioners now able to offer direct referrals to psychologists, social workers, occupational therapists and Aboriginal health workers. Incentives for better teamwork between GPs and other mental health professionals have been introduced, but may have unintended consequences, including an exacerbation of workforce shortages in rural and remote areas. Possible solutions to these shortages include rural scholarships for students in the mental health professions; recruitment and retention of students coordinated by university departments of rural health; better access to continuing professional development; and federally funded rural positions and additional financial incentives for rural mental health practitioners.<br /

Megacrystals track magma convection between reservoir and surface

Active volcanoes are typically fed by magmatic reservoirs situated within the upper crust. The development of thermal and/or compositional gradients in such magma chambers may lead to vigorous convection as inferred from theoretical models and evidence for magma mixing recorded in volcanic rocks. Bi-directional flow is also inferred to prevail in the conduits of numerous persistently-active volcanoes based on observed gas and thermal emissions at the surface, as well as experiments with analogue models. However, more direct evidence for such exchange flows has hitherto been lacking. Here, we analyse the remarkable oscillatory zoning of anorthoclase feldspar megacrystals erupted from the lava lake of Erebus volcano, Antarctica. A comprehensive approach, combining phase equilibria, solubility experiments and melt inclusion and textural analyses shows that the chemical profiles are best explained as a result of multiple episodes of magma transport between a deeper reservoir and the lava lake at the surface. Individual crystals have repeatedly travelled up-and-down the plumbing system, over distances of up to several kilometers, presumably as a consequence of entrainment in the bulk magma flow. Our findings thus corroborate the model of bi-directional flow in magmatic conduits. They also imply contrasting flow regimes in reservoir and conduit, with vigorous convection in the former (regular convective cycles of ∼150 days at a speed of ∼0.5 mm s−1) and more complex cycles of exchange flow and re-entrainment in the latter. We estimate that typical, 1-cm-wide crystals should be at least 14 years old, and can record several (from 1 to 3) complete cycles between the reservoir and the lava lake via the conduit. This persistent recycling of phonolitic magma is likely sustained by CO2 fluxing, suggesting that accumulation of mafic magma in the lower crust is volumetrically more significant than that of evolved magma within the edifice.The work reported here has been partially supported by the National Science Foundation (Division of Polar Programs) under grant ANT1142083.

The heme-hemopexin scavenging system is active in the brain, and associates with outcome after subarachnoid hemorrhage

Background and Purpose – Long-term outcome after subarachnoid hemorrhage (SAH) is potentially linked to cytotoxic heme. Free heme is bound by hemopexin (Hpx) and rapidly scavenged by CD91. We hypothesized that heme scavenging in the brain would be associated with outcome after haemorrhage. Methods - Using cerebrospinal fluid (CSF) and tissue from SAH patients and control individuals, the activity of the intracranial CD91-Hpx system was examined using enzyme-linked immunoassays, ultra-high performance liquid chromatography and immunohistochemistry. Results - In control individuals, CSF Hpx was mainly synthesized intrathecally. After SAH, CSF Hpx was high in one-third of cases, and these patients had a higher probability of delayed cerebral ischaemia and poorer neurological outcome. The intracranial CD91-Hpx system was active after SAH since CD91 positively correlated with iron deposition in brain tissue. Heme-Hpx uptake saturated rapidly after SAH, since bound heme accumulated early in the CSF. When the blood-brain barrier was compromised following SAH, serum Hpx level was lower, suggesting heme transfer to the circulation for peripheral CD91 scavenging. Conclusions - The CD91-heme-Hpx scavenging system is important after SAH and merits further study as a potential prognostic marker and therapeutic target

Nonverbal Auditory Cues Allow Relationship Quality to be Inferred During Conversations.

UNLABELLED: The claim that nonverbal cues provide more information than the linguistic content of a conversational exchange (the Mehrabian Conjecture) has been widely cited and equally widely disputed, mainly on methodological grounds. Most studies that have tested the Conjecture have used individual words or short phrases spoken by actors imitating emotions. While cue recognition is certainly important, speech evolved to manage interactions and relationships rather than simple information exchange. In a cross-cultural design, we tested participants' ability to identify the quality of the interaction (rapport) in naturalistic third party conversations in their own and a less familiar language, using full auditory content versus audio clips whose verbal content has been digitally altered to differing extents. We found that, using nonverbal content alone, people are 75-90% as accurate as they are with full audio cues in identifying positive vs negative relationships, and 45-53% as accurate in identifying eight different relationship types. The results broadly support Mehrabian's claim that a significant amount of information about others' social relationships is conveyed in the nonverbal component of speech.
