Misconceptions about density of decimals : insights from Indonesian pre-service teachers’ work

Extensive studies have documented various difficulties with, and misconceptions about, decimal numeration across different levels of education. This paper reports on pre-service teachers’ misconceptions about the density of decimals. Written test data from 140 Indonesian pre-service teachers, observation of group and classroom discussions provided evidence of pre-service teachers’ difficulties in grasping the density notion of decimals. This research was situated in a teacher education university in Yogyakarta, Indonesia. Incorrect analogies resulting from over generalization of knowledge about whole numbers and fractions were identified. Teaching ideas to resolve these difficulties and challenges in resolving pre-service teachers’ misconceptions are discussed. Evidence from this research indicates that it is possible to remove misconceptions about density of decimals.

Dedicated emergency theatres improve service delivery and surgeons' job satisfaction

Background
There are well-described benefits to separating emergency and elective surgery. Geelong Hospital lacked the resources to implement a separate acute surgical unit, but instituted daily dedicated emergency general surgery operating sessions, managed by an on-site consultant. This study aims to assess the impact of this on service delivery and surgeons' job satisfaction.
Methods
From 1 February 2011, daily half-day operating lists were allocated for general surgical emergencies. Patients treated on these lists were studied prospectively until 31 December 2011. Theatre waiting times and hospital stay were compared with the previous year. A quality-of-life questionnaire was administered to participating surgeons before the project commenced and after 6 months.
Results
A total of 966 patients underwent surgery during an emergency general surgery admission in the control period, and 984 underwent surgery during the study period. The median time from arrival in the emergency department (ED) to surgery was reduced from 19 (18–21) h in the control group to 18 (17–19) h in the study group (P = 0.033). The time from booking surgery to operation was reduced from 4.8 (4.3–5.4) h to 3.9 (3.5–4.3) h (P < 0.0001). For patients undergoing emergency laparotomy, the time from booking to surgery was reduced from 3.1 (2.2–4.1) to 2.4 (1.8–2.9) h, and hospital stay was reduced from 13 (11–15) to 10 (9–12) days (P = 0.0089). The surgeons' responses to the questionnaires showed improvement in job satisfaction (P < 0.0001).
Conclusion
This intervention has improved service delivery for emergency surgery patients, and improved the participating surgeons' job satisfaction.

Assessing for work integrated learning experiences : a pre-service teacher perspective

A critical aspect of the debate about work integrated learning in the university context is the blurring of boundaries and responsibilities in terms of student learning. In an Australian pre-service teacher education program this blurring of boundaries is apparent in stakeholder tensions about the nature and role of assessment during the practicum. In the study reported in this paper students responded positively to the content of assessment tasks but maintained that their efforts to implement the associated planning in the workplace were stymied because of disparate understandings between university and school staff about the purpose of the task.

Education and work in service of the nation: Canadian and Australian girls' fiction, 1908-1921

This chapter compares early twentieth-century Australian novels by Ethel Turner, Mary Grant Bruce, and Lilian Turner to Canadian novels by Nellie McClung and L.M. Montgomery to demonstrate important differences in attitudes towards education and work. Girls’ fiction in these white settler colonies has many similarities, containing strong ideals related to domesticity, education, employment, and femininity. In the Canadian fiction, attitudes towards women’s higher education and employement are generally much more positive. Although both Australian and Canadian girls’ fiction typically conclude with marriage, Montgomery’s Anne of Green Gables and Nellie McClung’s Pearlie Watson are offered the opportunity to pursue higher education and use this education to teach others. In contrast, Lilian Turner’s Paradise and the Perrys, Ethel Turner’s Fair Ines, and Mary Grant Bruce’s ’Possum emphasise the importance of domesticity while also showing how girls sought to earn income without leaving home. Through our comparison of these Canadian and Australian novels, all published between 1908 and 1921, we demonstrate how the different feminine ideals embodied through these heroines are inevitably intertwined with the needs of the nation

Cancer diagnosed in the emergency department of a regional health service

OBJECTIVE: Patients diagnosed with cancer in the Emergency Department (ED) have more advanced disease at diagnosis and poorer outcomes. High rates of initial presentation to ED suggest potential problems with access to care. The aim of this project was to interpret findings in regional/rural Victoria and explore implications for practice.

DESIGN: Cross-sectional study linking two independent data sets.

SETTING: Regional city of Geelong and surrounding rural areas in south-west Victoria.

PARTICIPANTS: All newly diagnosed cancer patients in 2009.

MAIN OUTCOME MEASURES: Number of cancer patients diagnosed in the ED.

RESULTS: One in five newly diagnosed cancer patients present to ED 6 months prior to cancer diagnosis. One in 10 is diagnosed as a result of their ED visit. Patients presenting to ED were older, more often men and from disadvantaged areas. Symptoms on presentation included chest complaints, bowel obstruction, abdominal pain, anaemia and generalised weakness. Cancer diagnosed in the ED is associated with advanced stage and shorter survival.

CONCLUSION: Reasons for presentation to ED would be multifactorial and include complex cases with coexisting symptoms making diagnosis difficult. The general public appear to have a low level of awareness of alternative primary care services or difficulty accessing such information. Some of the changes towards reducing the number of patients presenting to ED will include patient education.

Work ability among hospital food service professionals: multiple associated variables require comprehensive intervention

The work of hospital food service is characterized by demands that can be associated with work ability - WA. The aim of this study was to evaluate factors associated with WA among hospital food service professionals and recommend intervention measures. This is a cross sectional study carried out in 2009, conducted in a hospital of Sao Paulo, Brazil. Participants were 76 (96.2%) of the eligible. They filled out a questionnaire including socio-demographic data, life styles, working conditions and WA. Multivariate linear regression analyses were performed. Factors associated with WA were age (p=0.051), over commitment (p=0.011), effort-reward ratio (p=0.002) and work injuries (p<0.001). In spite was a young population, age was associated with WA. Association with work injuries is consistent with the theoretical model that demonstrated that health status is the basis to maintain the WA. The association of effort-reward imbalance shows that issues related with work organization are relevant for these workers. The association of overcommittment suggests that workers recognize their responsibility with the therapeutic processes of patients. Results showed a number of features of different nature that should be taken into account when implementing measures to improve the WA, to be applied at different levels: individual, task and institutional.

Accessibility and demand at an Emergency Care Unit: the user's perspective

AIM: To analyze the search for Emergency Care (EC) in the Western Health District of Ribeirão Preto (São Paulo), in order to identify the reasons why users turn to these services in situations that are not characterized as urgencies and emergencies. METHODS: A qualitative and descriptive study was undertaken. A guiding script was applied to 23 EC users, addressing questions related to health service accessibility and welcoming, problem solving, reason to visit the EC and care comprehensiveness. RESULTS: The subjects reported that, at the Primary Health Care services, receiving care and scheduling consultations took a long time and that the opening hours of these services coincide with their work hours. At the EC service, access to technologies and medicines was easier. CONCLUSION: Primary health care services have been unable to turn into the entry door to the health system, being replaced by emergency services, putting a significant strain on these services' capacity.
