Occupational aspirations of sixth-grade children

The present study examined the occupational aspirations of sixth-grade children in terms of occupational category, minimum education level and gender. In addition, the study identified the sources of occupational information used by the children and the factors they thought could influence them toward or away from a job. The study found that all of the children were able to express occupational aspirations. While the children obtained occupational information from a range of sources, including the media and family, the source most likely to influence them toward or away from choosing a job was family.

Identifying trajectories of adolescent smoking: An application of latent growth mixture modeling

The goal of the current study was to identify discrete longitudinal patterns of change in adolescent smoking using latent growth mixture modeling. Five distinct longitudinal patterns were identified. A group of early rapid escalators was characterized by early escalation (at age 13) that rapidly increased to heavy smoking. A pattern characterized by occasional puffing up until age 15, at which time smoking escalated to moderate levels was also identified (late moderate escalators). Another group included adolescents who, after age 15, began to escalate slowly in their smoking to light (0.5 cigarettes per month) levels (late slow escalators). Finally, a group of stable light smokers (those who smoked 1-2 cigarettes per month) and a group of stable puffers (those. who smoked only a few puffs per month) were also identified. The stable puffer group was the largest group and represented 25% of smokers.

Occupational Therapy in mental health: Managing stress and burnout

Stress and burnout for human service workers has received increasing attention over a number of years. It has been suggested that health care professionals may be particularly at risk of stress and burnout because of the amount and type of direct client contact that makes up their work. For workers in the field of mental health, additional stressors are present owing to organisational restructuring and new models of care. Mental health occupational therapists may be vulnerable to stress and burnout owing to the nature of their work, the types of client they see, the changed work environment and professional issues. It is recommended that occupational therapists become aware of the factors contributing to stress and burnout and develop strategies to maintain their wellbeing in the workforce.

Work-related stress and occupational therapy

Occupational stress and burnout have been studied extensively in the human services. It has been suggested that healthcare professionals in particular are at risk of stress owing to the caring nature of their work. Articles related to occupational therapy and work-related stress were reviewed in regard to practice in Australia, Canada, the United Kingdom, the United States and Sweden. Although the empirical literature is relatively weak for occupational therapy, it has been argued that occupational therapists in health care share risk factors with other healthcare professionals. These risk factors include repeated exposure to distress and difficult behaviour, prolonged interventions and uncertain outcome. Issues such as professional status, staffing issues and the nature of the profession have been identified as additional risk factors for occupational therapists. However, empirical studies that enable burnout rates of occupational therapists to be compared with those of related occupational groups suggest that this may not be the case. Occupational therapists may in fact be protected from some stress and burnout factors. Further research is recommended to clarify the nature of stress experienced by occupational therapists and to identify both risk and protective factors characteristic of the profession.

Relationships between non-occupational cadmium exposure and expression of nine cytochrome P450 forms in human liver and kidney cortex samples

This study was undertaken to assess associations between age, gender, cigarette smoke and non-workplace cadmium exposure, and liver pathology and inter-individual variation in cytochrome P450 (CYP) expression in human tissues. Autopsy specimens of twenty-eight Queensland residents whose ages ranged from 3 to 89 years were analyzed for the presence of nine CYP protein isoforms by immunoblotting. All subjects were Caucasians and their liver cadmium contents ranged from 0.11 to 3.95 kg/g wet weight, while their kidney cadmium contents were in the range of 2 to 63 mug/g wet weight. CYP1A2, CYP2A6, CYP2D6, CYP3A4, and CYP3A5 were detected in liver but not in kidney, and CYP1A1 and CYP1B1 were not found in liver or kidney. Lowered liver CYP2C8/19 protein contents were found to be associated with liver pathology. Importantly, we show elevated levels of CYP2C9 protein to be associated with cadmium accumulation in liver. No mechanism that explains this association is apparent, but there are two possibilities that require further study. One is that variation in CYP2C9 protein levels may be, in part, attributed to an individual's non-workplace exposure to cadmium, or an individual's CYP2C9 genotype may be a risk factor for cadmium accumulation. A positive correlation was found between liver CYP3A4 protein and subject age. Levels of liver CYPIA2 protein, but not other CYP forms, were increased in people more exposed to cigarette smoke, but there was no association between CYPIA2 protein and cadmium. CYP2A6 protein was found in all liver samples and CYP2A6 gene typing indicated the absence of CYP2A6 null allele (CYP2A6(D)) in this sample group, confirming very low prevalence of homozygous CYP2A6(D) in Caucasians. CYP2A6 gene types W/W, WIC, and CIC were not associated with variations in liver microsomal CYP2A6 protein. CYP2D6 protein was absent in all twenty-five kidney samples tested but was detectable in liver samples of all but two subjects, indicating the prevalence of the CYP2D6 null allele (CYP2D6(D)) in this sample group to be about 7%, typical of Caucasian populations.

Scoring occupational categories for social research: A review of current practice, with Australian examples

The scoring of occupational categories has along history. After reviewing the historical background, we develop and discuss the properties of two new Australian scales based on current theorising in stratification research. The first is based on the operation of the labour market and scores occupations to reflect their central role in converting educational credentials into market income. The second is based on patterns of social interaction and scores occupations to reflect the choices that people make in marriage markets. While these two scales are not theoretically or empirically equivalent, they are closely related and provide equally valid, but alternative, ways of measuring the underlying stratification order of modern societies.

Changing pay systems, occupational concentration and the gender pay gap: Evidence from Australia and the UK

While aggregate level pay equity comparisons between Australia and the UK confirm expectations based on their different wage distributions and regulatory systems, observation of trends and occupational level analysis reveal additional complexity. Our analysis suggests the need for a multi-faceted approach to closing the average gender pay gap.

Dynamic assessment of tongue function in children with dysarthria associated with acquired brain injury using electromagnetic articulography

The study to be presented is the first to use a new physiological device, the electromagnetic articulograph, to assess articulatory dysfunction in children with acquired brain injury. Two children with dysarthria subsequent to acquired brain injury participated in the study. One child, a female aged 12 years 9 months exhibited a mild-moderate ataxic dysarthria following traumatic head injury while the other, a male aged 13 years 10 months, demonstrated a moderate-severe flaccid-ataxic dysarthria also following traumatic head injury. The speed and accuracy of their tongue movements was assessed using the Carstens AG100 electromagnetic articulograph. Movement trajectories together with a range of quantitative kinematic parameters were estimated during performance of ten repetitions of the lingual consonants /t, s, k/ and consonant cluster /kl/ in the word initial position of single syllable words. A group of ten non-neurologically impaired children served as controls. Examination of the kinematic parameters, including movement trajectories, velocity, acceleration, deceleration, distance travelled and duration of movement, revealed differences in the speed and accuracy of the tongue movements in both children with acquired brain injury compared to those produced by the non-neurologically impaired controls. The results are discussed in relation to contemporary theories of the effects of acquired brain injury on neuromuscular function. The implications of the findings for the treatment of articulatory dysfunction in children with motor speech disorders associated with acquired brain injury are highlighted.
