Online counselling: The motives and experiences of young people who choose the internet instead of face to face or telephone counselling

This study used a Consensual Qualitative Research methodology to explore the motivations and experiences of young people who utilize the Internet for counselling over other counselling media. Semi-structured online group interviews (focus groups) were conducted with 39 participants from the Kids Help Line, a 24-hour national telephone and counselling service located in Australia. Analysis revealed five domains relevant to the adolescents' motives and experiences and the frequency of categories within and across cases were analyzed to generate and understand themes and patterns. Specific motivators and barriers are identified and discussed, as are implications for practice and continued research.

To fix or not to fix: The role of 2-phenoxyethanol in rabbit, Oryctolagus cuniculus, chin gland secretion

The European rabbit (Oryctolagus cuniculus) uses the secretion of the chin gland to maintain dominance hierarchies in the wild. Recent work has investigated changes in the secretion when social status is manipulated in the rabbit. When a rabbit becomes dominant, a new compound appears in his secretion, 2-phenoxyethanol. This compound is used as a fixative in the perfume industry. This study investigates whether the compound performs a similar function in the secretion of the rabbit. 2-Phenoxyethanol is not detected olfactorially by rabbits, and slows the release rate of some of the compounds that occur naturally in rabbit chin gland secretion. We suggest that when a rabbit becomes dominant, he adds a fixative to his secretion so that his scent will persist in the environment and not dissipate. He will thus come to dominate the olfactory environment, in much the same way as he does the physical environment.

Irritative symptoms after colposuspension: Are they due to distortion or overelevation of the anterior vaginal wall and trigone?

Symptoms of bladder irritability are common after incontinence surgery but their cause is unknown. This study tests the hypothesis that irritative symptoms after colposuspension are due to distortion of the trigone. As part of longitudinal follow-up studies, 175 women were examined 6 months to 12 years after either an open or a laparoscopic Burch colposuspension. The main outcome measures were symptoms of bladder irritability (frequency, nocturia and urge incontinence) and ultrasound findings (bladder neck position at rest and on Valsalva, the presence of a colposuspension ridge, ridge depth and ridge distance, and trigonal angle). Two positive associations between ultrasound parameters and symptoms of bladder irritability were observed: urge incontinence was more likely in the presence of bladder neck funneling, and women with nocturia had a higher trigonal angle. Increased distortion of the trigone was associated with a reduced incidence of urge incontinence in the subgroup of patients after laparoscopic colposuspension. The data presented in this study do not support the hypothesis that symptoms of bladder irritability are due to trigonal distortion or overelevation.

Responsibility to protect or Trojan Horse? The crisis in darfur and humanitarian intervention after Iraq

What does the world's engagement with the unfolding crisis in Darfur tell us about the impact of the Iraq war on the norm of humanitarian intervention? Is a global consensus about a "responsibility to protect" more or less likely? There are at least three potential answers to these questions. Some argue that the merging of strategic interests and humanitarian goods amplified by the intervention in Afghanistan makes it more likely that the world's most powerful states will act to prevent or halt humanitarian crises. Others insist that the widespread perception that the United States and its allies "abused" humanitarian justifications to legitimate its invasion of Iraq has set back efforts to build a global consensus about humanitarian action. A third group argues that the "responsibility to protect" inhibits the potential for abuse and, as a result, consensus is likely to strengthen post-Iraq for precisely this reason. Through a detailed study of the international engagement with Darfur, I suggest that the latter two arguments have merit but need to be adjusted. I argue that the humanitarian intervention norm has changed in two subtle ways. First, while the strength of the norm itself has not changed, the credibility of the United States and U.K. as "norm carriers" has been significantly undermined. Second, while the "responsibility to protect" has been invoked to support international activism, it has also re-legitimated anti-interventionist arguments.

To marry or not to marry: marital status and the household division of labour

Data from an Australian national survey (1996 to 1997) are used to examine domestic labor patterns among de facto and married men and women. The results show that women spend more time on housework and do a greater proportion of housework than men. However, the patterns are most traditional among married men and women. Women in de facto relationships spend less time doing housework and do a smaller proportion of indoor activities than married women. Men in de facto relationships do a larger proportion of indoor activities and a lower proportion of outdoor tasks than married men. The data also show that couples who have cohabited prior to marriage have more egalitarian divisions of labor than those who have not cohabited prior to marriage. This article concludes by arguing that the incompleteness of the de facto relationship provides a period of relative freedom in which to negotiate more equal roles.

To self, or not to self ... A review of outcrossing and pollen-mediated gene flow in neotropical trees

Despite the typically low population densities and animal-mediated pollination of tropical forest trees, outcrossing and long-distance pollen dispersal are the norm. We reviewed the genetic literature on mating systems and pollen dispersal for neotropical trees to identify the ecological and phylogenetic correlates. The 36 studies surveyed found >90% outcrossed mating for 45 hermaphroditic or monoecious species. Self-fertilization rates varied inversely with population density and showed phylogenetic and geographic trends. The few direct measures of pollen flow (N = 11 studies) suggest that pollen dispersal is widespread among low-density tropical trees, ranging from a mean of 200 m to over 19 km for species pollinated by small insects or bats. Future research needs to examine (1) the effect of inbreeding depression on observed outcrossing rates, (2) pollen dispersal in a wide range of pollination syndromes and ecological classes, (3) and the range of variation of mating system expression at different hierarchical levels, including individual, seasonal, population, ecological, landscape and range wide.

Seronegative spondyloarthropathies: To lump or split?

The advent of novel biological therapies for the treatment of rheumatic disease has renewed interest in the seronegative spondyloarthropathies (SpAs). International efforts are redefining disease classification and measures of disease activity, outcome, metrology, and imaging. However, opinion is divided between those who propose that the SpA group represents the same disease with variable expression (the lumpers) and those who consider these to be separate diseases with shared clinical features (the splitters). This review presents the evidence for both approaches.

Modelling cell lifespan and proliferation: is likelihood to die or to divide independent of age?

In cell lifespan studies the exponential nature of cell survival curves is often interpreted as showing the rate of death is independent of the age of the cells within the population. Here we present an alternative model where cells that die are replaced and the age and lifespan of the population pool is monitored until a, steady state is reached. In our model newly generated individual cells are given a determined lifespan drawn from a number of known distributions including the lognormal, which is frequently found in nature. For lognormal lifespans the analytic steady-state survival curve obtained can be well-fit by a single or double exponential, depending on the mean and standard deviation. Thus, experimental evidence for exponential lifespans of one and/or two populations cannot be taken as definitive evidence for time and age independence of cell survival. A related model for a dividing population in steady state is also developed. We propose that the common adoption of age-independent, constant rates of change in biological modelling may be responsible for significant errors, both of interpretation and of mathematical deduction. We suggest that additional mathematical and experimental methods must be used to resolve the relationship between time and behavioural changes by cells that are predominantly unsynchronized.
