Parent cognitions and parent-infant interaction: the relationship with development in the first 12 months

This study examined parent cognitions and parent-infant interaction in terms of their contribution to infant development in the first 12 months. With a sample of 95 mother-infant dyads, results using structural equation modelling confirmed the expected finding that parent-infant interaction mediates the association between parent cognitions and infant development. An unexpected finding was that the direct association between parent cognitions and infant development was stronger than the direct association between parent-infant interaction and infant development. These findings are discussed with regard to the implications for preventative and early intervention models.

Bone geometry in response to long-term tennis playing and its relationship with muscle volume : a quantitative magnetic resonance imaging study in tennis players

The benefit of impact-loading activity for bone strength depends on whether the additional bone mineral content (BMC) accrued at loaded sites is due to an increased bone size, volumetric bone mineral density (vBMD) or both. Using magnetic resonance imaging (MRI) and dual energy X-ray absorptiometry (DXA), the aim of this study was to characterize the geometric changes of the dominant radius in response to long-term tennis playing and to assess the influence of muscle forces on bone tissue by investigating the muscle–bone relationship. Twenty tennis players (10 men and 10 women, mean age: 23.1 ± 4.7 years, with 14.3 ± 3.4 years of playing) were recruited. The total bone volume, cortical volume, sub-cortical volume and muscle volume were measured at both distal radii by MRI. BMC was assessed by DXA and was divided by the total bone volume to derive vBMD. Grip strength was evaluated with a dynamometer. Significant side-to-side differences (P < 0.0001) were found in muscle volume (+9.7%), grip strength (+13.3%), BMC (+13.5%), total bone volume (+10.3%) and sub-cortical volume (+20.6%), but not in cortical volume (+2.6%, ns). The asymmetry in total bone volume explained 75% of the variance in BMC asymmetry (P < 0.0001). vBMD was slightly higher on the dominant side (+3.3%, P < 0.05). Grip strength and muscle volume correlated with all bone variables (except vBMD) on both sides (r = 0.48–0.86, P < 0.05–0.0001) but the asymmetries in muscle parameters did not correlate with those in bone parameters. After adjustment for muscle volume or grip strength, BMC was still greater on the dominant side. This study showed that the greater BMC induced by long-term tennis playing at the dominant radius was associated to a marked increase in bone size and a slight improvement in volumetric BMD, thereby improving bone strength. In addition to the muscle contractions, other mechanical stimuli seemed to exert a direct effect on bone tissue, contributing to the specific bone response to tennis playing.

Volunteering and its relationship with personal and neighborhood well-being

Although a relationship between volunteering and well-being has been demonstrated in numerous studies, well-being has generally been poorly operationalized and often defined by the relative absence of pathology. In this study, the authors take a positive approach to defining well-being and investigate the relationship between volunteering and personal and neighborhood well-being. The theoretical approach incorporates elements of the homeostatic model of well-being. A sample of 1,289 adults across Australia completed a questionnaire that assessed personal and neighborhood wellbeing, personality factors, and the psychosocial resources implicated in the homeostatic model of well-being. Analyses reveal that volunteers had higher personal and neighborhood well-being than nonvolunteers and that volunteering contributed additional variance in well-being even after psychosocial and personality factors were accounted for. The findings are discussed in terms of previous research and the homeostatic model of well-being, and it is argued that the relationship between volunteering and well-being is robust.

Developing a relationship with place : art in the context of bioregional theory and practice

Investigates a proposed solution to Western culture's essentially separatist and destructive relationship with the earth from the perspective of the artist. Examines the author's bioregional philosophical model which is based on a belief in the importance of place in physical and spiritual well-being and argues that it is an appropriate one to apply in the context of contemporary Australian art practice.

Students' use of online academic resources within a course web site and its relationship with their course performance : an exploratory study

Prior research suggests that the online provision of course materials can have a positive impact on students' examination performance. This study adds to the existing literature by investigating the link between the students' use of different forms of online course provisions and tools (i.e. course materials, links and discussion forums) and the final examination performance of students in a second year undergraduate accounting course. Findings indicate a positive association between the number of online files viewed by students, the number of online discussion messages posted by them, and their examination performance. A significant relationship was not found between examination performance and the amount of time spent on the subject's web site, the viewing of links to web sites that were not core to the course being studied, or the passive reading of discussion messages. These findings support the benefits to be gained by providing course materials online and encouraging students to access the materials posted and to participate actively in online discussion.

Childhood cruelty to animals in China: the relationship with psychological adjustment and family functioning

Background
The current study broadened the general scope of research conducted on childhood cruelty to animals by examining the association between psychological adjustment, family functioning and animal cruelty in an Eastern context, China.

Method
The mothers and fathers of 729 children attending primary school in Chengdu, China participated in this study. Each parent completed the Strengths and Difficulties Questionnaire, the Chinese Family Assessment Instrument, and the Children's Attitudes and Behaviours towards Animals questionnaire.

Results
Findings from an actor partner interdependence model demonstrated that parents' ratings of family functioning and of their child's externalizing coping style predicted only modest amounts of variance in animal cruelty. In particular, parents' ratings of their child's externalizing coping style most consistently predicted animal cruelty. Family functioning, fathers' ratings in particular, played a minor role, more so for boys compared with girls.

Conclusion
This study provided the first insight into childhood animal cruelty in China, and suggests that further research may enhance our understanding of these phenomena.

Long-term ethylene oxide exposure trends in US hospitals : relationship with OSHA regulatory and enforcement actions

We assessed long-term trends in ethylene oxide (EtO) worker exposures for the purposes of exposure surveillance and evaluation of the impacts of the Occupational Safety and Health Administration (OSHA) 1984 and 1988 EtO standards. We obtained exposure data from a large commercial vendor and processor of EtO passive dosimeters. Personal samples (87 582 workshift [8-hr] and 46 097 short-term [15-min] samples) from 2265 US hospitals were analyzed for time trends from 1984 through 2001 and compared with OSHA enforcement data. Exposures declined steadily for the first several years after the OSHA standards were set. Workshift exposures continued to taper off and have remained low and constant through 2001. However, since 1996, the probability of exceeding the short-term excursion limit has increased. This trend coincides with a decline in enforcement of the EtO standard. Results indicate the need for renewed intervention efforts to preserve gains made following the passage and implementation of the 1984 and 1988 EtO standards.

Nasdijj's fake magical realist memoir: re-visioning magical realism's relationship with fakery

Examining what might be described as Nasdijj’s "fake magical realist memoir" The Blood Runs Like a River Through My Dreams, this paper is interested in how Nasdijj's text might be useful in contesting our understanding of the postcolonial literature of magical realism. Drawing attention to Nasdijj’s utilization of the “primitivist” conventions of magical realism, this paper will illustrate how fakery might be seen as essential not only to Nasdijj's text but also to magical realism. In fact, this paper argues that magical realist novels might be productively read as hoaxes, mobilizing what Graham Huggan describes as the "postcolonial exotic" in order to engage in a subversive act of “culture jamming”. The objective of the analysis is not to condemn magical realism along with Nasdijj’s opportunistic memoir, but rather to rescue magical realism from ideas about authenticity, celebrating its ironies and its challenges to colonial discourses of identity and history.
