Application of Chiral Lanthanide-induced Shift Reagents to Optically Active Cations: the Use of Tris[3-(trifluoromethylhydroxymethylene)-( + )-camphorato]europium(III) to Determine the Enantiomeric Purity of Tris(phenanthroline)ruthenium(II) Dichloride
In non-polar solvents, chiral europium complexes provide attractive n. m. r. shift reagents to resolve spectra of optically active cations, and, in particular, for tris(phenanthroline)ruthenium dichloride,^1H n. m. r. shift differences of up to 0.7 p.p.m. between isomers easily permit the determination of absolute enantiomeric purity
Compassion in the emergency department. Part 3: enabling and supporting the delivery of compassionate care
In the final part of this three-part series, David Hunter and colleagues analyse the factors that enable and support delivery of compassionate care in emergency departments (EDs). Part one reported findings from doctoral-level research that explored nursing students' experiences of compassionate care in EDs, while part two considered the barriers to such care identified by the students. This article highlights and celebrates the ways in which emergency nurses provide compassionate care despite the challenges they face

Solitary fibrous tumour of the nose and nasopharynx
A case of solitary fibrous tumour of the nasal cavity is reported. These tumours, rare in the nose, are believed to be similar to fibrous mesotheliomas of the pleural cavity. The main presenting symptom is that of unilateral nasal obstruction and diagnosis is made on histological examination of the lesion. These tumours have to be distinguished from other spindle-cell tumours of the nasal cavity and sinuses.peer-reviewe
Demographic change and employment in the Central North Island, 1986-1996
This paper examines some dimensions of demographic and economic change in a region which is generally considered to be one of the most productive and affluent parts of New Zealandâs âheartlandâ. The paper highlights considerable demographic and economic diversity within the Central North Island. This is a complex region in terms of its population composition, its mix of rural and urban places and industries, and its linkages to other parts of New Zealandâs society and economy. The consistently poorer performance found in a wide range of indices of social and economic change in this part of New Zealand is
very sobering

Illuminating Massive Black Holes With White Dwarfs: Orbital Dynamics and High Energy Transients from Tidal Interactions
White dwarfs (WDs) can be tidally disrupted only by massive black holes
(MBHs) with masses less than . These tidal interactions feed
material to the MBH well above its Eddington limit, with the potential to
launch a relativistic jet. The corresponding beamed emission is a promising
signpost to an otherwise quiescent MBH of relatively low mass. We show that the
mass transfer history, and thus the lightcurve, are quite different when the
disruptive orbit is parabolic, eccentric, or circular. The mass lost each orbit
exponentiates in the eccentric-orbit case leading to the destruction of the WD
after several tens of orbits. We examine the stellar dynamics of clusters
surrounding MBHs to show that single-passage WD disruptions are substantially
more common than repeating encounters. The erg s peak
luminosity of these events makes them visible to cosmological distances. They
may be detectible at rates of as many as tens per year by instruments like
Swift. In fact, WD-disruption transients significantly outshine their
main-sequence star counterparts, and are the most likely tidal interaction to
be detected arising from MBHs with masses less than . The
detection or non-detection of such WD-disruption transients by Swift is,
therefore, a powerful tool to constrain lower end of the MBH mass function. The
emerging class of ultra-long gamma ray bursts all have peak luminosities and
durations reminiscent of WD disruptions, offering a hint that WD-disruption
transients may already be present in existing datasets.Comment: Revised following response from refere
The Canine Behaviour Type Index
While working intensively with companion dogs it emerged that certain behavior types present particular management challenges in a domestic setting. Gosling, Kwan, John & Oliver validated the concept of dogs having a distinct measurable personality type (Gosling, Kwan, John, Oliver 2003 A Dog's Got Personality: A Cross-Species Comparative Approach to Personality Judgments in Dogs and Humans Journal of Personality & Social Psychology. 2003 Dec Vol 85(6) 1161-1169). Our team (Pet Connect) developed The Canine Behavior Type Index (CBTI) (Patent Pending) typing companion dogs into 12 distinct profiles. There are 3 psychological dimensions: (1) Environmental Order (either Organized or Spontaneous); (2) Social Order (either Alpha, Beta, or Gamma); (3) Motivation (either Medium or High) giving 12 possible outcomes. The CBTI is not breed specific though breeds may cluster around particular profiles. Questions were administered to 50 volunteer pet dog owners with 1-3 dogs each. Each owner played a board game in solitude. The board game has twenty-six two-sided cards with opposing statements about the dog. The owner selects the most appropriate statement about their dog. There were nine cards for each of the Environmental Order and Motivation dimensions, and eight for the Social Order dimension. The CBTI type was decided according to a majority of answers, then the corresponding CBTI printed profile given to the owner. The owner filled in a questionnaire about the perceived accuracy of the CBTI printed profile to their companion dog. In preliminary statistical analysis, the owner perceived accuracy ranged from 70-100 percent. The person administering the test was a Veterinary Behaviorist who also typed each dog independently of the owner, based on behavioral questions and observations. The correlation between the owners and the researcher's selected CBTI type is P is less than .01. The CBTI recognizes that certain canine psychological profiles best suit specific tasks and lifestyles. A behavior management plan was tailored to meet the specific needs of each CBTI profile. Each dog requires exercise, deference, environmental enrichment, rapport and respect exercises, though the relative importance and style of each exercise depends on the dog's CBTI profile
Wildlife-Based Tourism, Ecology and Sustainability of Protected Areas in Kenya
Tourism plays a hugely significant role in Kenyaâs economy, contributing to approximately 25% of Kenyaâs Gross Domestic Product (GDP). Wildlife tourism to Kenyaâs numerous National Parks and Reserves represents a substantial part of this, with around 70% of tourism revenue in Kenya coming from wildlife tourism. Ecotourism has been recommended as a sustainable development option particularly for the ecologically depressed and underdeveloped regions of the world which have little potential for development. Tourism has been recommended as a sustainable development option particularly for the economically depressed and underdeveloped regions of the world that have little potential for development (Akama, 1999). McIntyre (1993, p. 10) defined sustainable development as: A process which allows development to take place without degrading or depleting the resources which make the development possible. This is generally achieved either by managing the resources so that they are able to renew themselves at the same rate at which they are used, or switching from the use of a slowly regenerating resource to one that regenerates more rapidly. In this way, resources remain able to support future as well as current generations
