Changes over time in sexual and relationship functioning of people with multiple sclerosis

Relationship and sexual satisfaction among people with multiple sclerosis (MS) has received little research attention. This article reports on a longitudinal investigation of the impact of coping style and illness-related variables among people with MS and the general population on sexual and relationship functioning. Both men (n = 120) and women (n= 201) with MS and men (n = 79) and women (n = 160) from the general population participated in the study at two points in time, 6 months apart. People with MS experienced lower levels of sexual activity, sexual satisfaction, and relationship satisfaction and higher levels of sexual dysfunction. Generally speaking, the time 1 levels of the health and coping variables explained little of the variance in the time 2 sexual and relationship variables. However, sexual activity at time 1 contributed significant unique variance to relationship satisfaction at time 2 for MS men, and coping strategies at time I contributed to relationship satisfaction among general population women at time 2. Furthermore, for those respondents who had been diagnosed with MS for less than 7 years, levels of sexual activity at time 2 were predicted by levels of sexual and relationship satisfaction, as well as levels of sexual activity at time 1. These results suggest that strategies used to cope with illness may not play a major role in sexual and relationship satisfaction. However, an examination of these strategies over a longer time frame is needed.

Ageing effects on visual reaction time in a single task condition and when treadmill walking

Visual reaction time (RT) was measured in 10 older men (mean age, 71.1 years) and gender-matched controls (mean age, 26.3 years) when standing (single task) and when walking on a motor-driven treadmill (dual task). There were 90 quasirandomly presented trials over 15 min in each condition. Longer mean and median RTs were observed in the dual task compared to the single task. Older males had significantly slower mean and median RTs (315 and 304 ms, respectively) than the younger group (273 and 266 ms, respectively) in both task conditions. There were no age or condition effects on with in-subject variability. Both groups showed a trend of increasing RT over the 90 single task trials but when walking only the younger group slowed. These novel findings demonstrate high but sustained attention by older adults when walking. It is proposed that the motor task's attentional demands might contribute to their slower preferred walking speed.

Preparing Australia's future lawyers: an exposition of changing values over time in the context of teaching about ethical dilemmas

This study investigated what values may be influential to decision making in relation to ethical behaviour for early career lawyers. It adopted a longitudinal approach to investigate how values develop or degrade over time as final year law students move into their first two years of employment or further study. To this end, the study investigated the role that tertiary education and employers fulfill in building and perpetuating ‘appropriate’ professional values? Results demonstrate that, in general, ethical behaviour was not uniformly reinforced over time in the workplace. The undertaking of pro bono work stands out here. Results suggested that certain behaviour relevant values may develop or degrade over the early years of the Australian lawyer's career. The implications of results are discussed in the contexts of ethics education in a tertiary context and the continuing education and regulation of the legal profession.

"Where myth becomes history" : the politics of mythical time in Heiner Muller's Medea

Heiner Müller in the 1980s produced a sequence of plays featuring Euripides’ heroine Medea using his distinctive, poetic modality of “the theatre of images”. These ostensibly postmodern narratives take the form of disjointed, visual and textual representations that are also fragmentations of historical and mythical times and spaces. Müller’s Medea plays are thus suggestive of the intersection between the discourses of history and myth — and the blending of historical time with ahistorical, supposedly “timeless” mythical narratives. Further, the postmodern possibility of history’s textuality to liquidate it into a type of (modern) mythology seeks expression in the plays’ representation of a converse equation: the moment signaled in the text as that “where myth becomes history”. This paper examines the problematisation of the myth-history dichotomy in Müller’s Medea plays, outlining the ways in which the “timeless” myth of the classical, infanticidal figure of Medea is strategically deployed to politicise evolutionist teleology, Western colonialism and the technologies of war in twentieth century Europe.

Engagement and learning through social software in finance : the trading room experience

The introduction of a social software blog space called “The Trading Room” in an undergraduate Finance unit for an assessment task generated a great deal of activity to support student learning. A subsequent evaluation of this pilot demonstrated that students perceived high value in the opportunity it provided for them to reaffirm theories, obtain individualized feedback and benchmark their work against others. Whilst assessment is generally seen as both the carrot and the stick of learning, and certification; students in the study reported that they would still participate in reading and posting to the “Trading Room” blog even if there was no assessment requirement! Additionally they did not see any value in the environment as a purely social space, reporting that they saw it primarily as a professional educational community. It would appear that just as there are different communities in the real world social space, there are also different types of communities in the online space. Context, structure and activity design, perhaps are the most important facets of online interaction for learning.

Passing time in Clifton Court : an ethnographic study of a unit for confused older people

An exploration of how the residents of a 30 bed unit for confused older people spent their time and a description of the impact upon this of any associated factors. The study demonstrates that it is possible for for elders with dementia and mental health problems to enjoy a range of activities, however, these need to be individualised to take into account the skills they have to meet the challenges with which they are presented. The informed contribution from the activities personnel and the support of nurses is vital to ensure a high quality of social interaction. Sound leadership at the clinical level is essential.

Socio-demographic correlates of prolonged television viewing time in Australian men and women : the AusDiab study

Background: Sedentary behaviors, particularly television viewing (TV) time, are associated with adverse health outcomes in adults, independent of physical activity levels. These associations are stronger and more consistent for women than for men. Methods: Multivariate regression models examined the sociodemographic correlates of 2 categories of TV time (≥2 hours/day and ≥4 hours/day); in a large, population-based sample of Australian adults (4950 men, 6001 women; mean age 48.1 years, range 25-91) who participated in the 1999/2000 Australian Diabetes, Obesity, and Lifestyle (AusDiab) study. Results: Some 46% of men and 40% of women watched ≥ 2 hours TV/day; 9% and 6% respectively watched ≥ 4 hours/day. For both men and women, ≥2 hours TV/day was associated with less than tertiary education, living outside of state capital cities, and having no paid employment. For women, mid and older age (45-64 and 65+) were also significant correlates of ≥2 hours TV/day. Similar patterns of association were observed in those viewing ≥4 hours/day. Conclusions: Prolonged TV time is associated with indices of social disadvantage and older age. These findings can inform the understanding of potential contextual influences and guide preventive initiatives.

Application of sequential nonparametric confidence bands in finance

In a nonparametric setting, the functional form of the relationship between the response variable and the associated predictor variables is assumed to be unknown when data is fitted to the model. Non-parametric regression models can be used for the same types of applications such as estimation, prediction, calibration, and optimization that traditional regression models are used for. The main aim of nonparametric regression is to highlight an important structure in the data without any assumptions about the shape of an underlying regression function. Hence the nonparametric approach allows the data to speak for itself. Applications of sequential procedures to a nonparametric regression model at a given point are considered.

The primary goal of sequential analysis is to achieve a given accuracy by using the smallest possible sample sizes. These sequential procedures allow an experimenter to make decisions based on the smallest number of observations without compromising accuracy. In the nonparametric regression model with a random design based on independent and identically distributed pairs of observations (X ,Y ), where the regression function m(x) is given bym(x) = E(Y X = x), estimation of the Nadaraya-Watson kernel estimator (m (x)) NW and local linear kernel estimator (m (x)) LL for the curve m(x) is considered. In order to obtain asymptotic confidence intervals form(x), two stage sequential procedure is used under which some asymptotic properties of Nadaraya-Watson and local linear estimators have been obtained.

The proposed methodology is first tested with the help of simulated data from linear and nonlinear functions. Encouraged by the preliminary findings from simulation results, the proposed method is applied to estimate the nonparametric regression curve of CAPM.

Blended learning in finance : comparing student perceptions of lectures, tutorials and online learning environments across different year levels

In modern pedagogy, a blended approach is used comprising both face-to-face and online learning. This study investigates how undergraduate students majoring in finance view the different learning environments, and evaluates the changes in perception over the three years of the degree after controlling for gender, age, international/domestic student and English as a first language. Using a purpose designed survey instrument, students across the three years of undergraduate study rated the importance of lectures, tutorials and web-based learning environments in a blended learning model. The results indicate that there is still a strong preference for face-to-face learning. Additionally, there were significant differences in attitudes and perception by year level.

Creating a dialogue across time in Athens : the new Acropolis museum and the Parthenon

A visit to the New Acropolis Museum in Athens, Greece, in late June 2010 set in train a number of questions and inspired a research project to begin to unravel something of the complex relationship between ancient and modern architecture on the Athenian Acropolis. Research was guided by the question: how does the contemporary museum, designed by Swiss born architect Bernard Tschumi in collaboration with local Greek architect Michalis Photiadis relate to the ancient Acropolis and the fifth century BC Parthenon, whose sculptures it was to house? A critical literature review was augmented by design analysis and field experience. This paper documents the resulting critical thematic investigations of the Parthenon, the Acropolis and the New Museum through siting, materiality and light, alignment, visual connections, through exploitation of the unique Attic light, orchestrated movement and considered juxtapositions. Research has revealed that Tschumi’s deliberate strategy of creating a dialogue between his building and the ancient monuments holds the key to his design intent, to creatively exploring contemporary architecture at the edge of such a physically and culturally dominant ancient plateau.

Real-time, in-situ, extinction spectroscopy studies on silver-nanoseed formation

In this paper, real-time extinction spectroscopy was employed to analyze in situ the fast formation process of silver seeds. The influencing factors for silver-seed formation, including the concentration of the reducer (NaBH 4), the amount of stabilizer (citrate), and the addition procedure of NaBH4, were evaluated. The configuration of the surface plasmon resonance (SPR) spectra of silver nanoparticles, which reflected the morphology of the produced silver seeds, was found to be distinctly affected by the NaBH4 concentration. Homogeneous silver nanoparticles were obtained when the added NaBH4 was lower in concentration than 2.00 mM. In contrast, higher concentrations of reducing agent (>3.00 mM NaBH4) resulted in uneven silver nanoparticles. Mie theory was applied to clarify the correlation of the SPR and the size of the silver seeds. Repeated additions of a small amount of the reducing agent could increase the monodispersity and isotropy of silver seeds. Real-time extinction spectroscopy is a convenient technique that achieves the in-situ and nondestructive measurement of intermediates in the formation process of silver nanoseeds.

Comparing different accelerometer cut-points for sedentary time in children

Actigraph accelerometers are hypothesized to be valid measurements for assessing children's sedentary time. However, there is considerable variation in accelerometer cut-points used. Therefore, we compared the most common accelerometer sedentary cut-points of children performing sedentary behaviors. Actigraph Actitrainer uniaxial accelerometers were used to measure children's activity intensity (29 children, 5-11 years old) during different activities, namely playing computer games, nonelectronic sedentary games, watching television and playing outdoors. A structured protocol was the criterion for assessing the validity of four common cut-points (100, 300, 800, 1100 counts/minute). The median counts during all sedentary behaviors were below the lowest comparison cut-point of 100 cpm. The 75th percentile values for the sedentary behaviors were always below the cut-point of 300 cpm. Our results suggest that the cut-point of <100 cpm is the most appropriate.
