Student attention, engagement and participation in a Twitter-friendly classroom

Guided by a participatory action research methodology, this paper outlines an approach to integrating the social media Twitter platform within a tertiary education course, based on a social, constructivist pedagogy. It explores the perceptions of students on the benefits of using this technology for enhancing attentiveness, engagement and participation in the classroom. Previous studies have shown that greater participation and communication can stimulate student learning and lead to better academic performance, increased motivation, and an appreciation of different points of views. The untested hypothesis is that social media tools like Twitter can foster this type of communication. Students posted their responses during classroom activities via Twitter and then were surveyed on their perceived benefits associated with using the social media platform. The preliminary findings of the qualitative study suggest that, while not without its challenges, social media tools like Twitter have the potential to be used effectively for education-based activities in the classroom to improve communication and engagement both amongst the students and with the instructor.

Tropes of friendship, undercurrents of fear : alternative emotions on the friendly frontier

This article examines a conciliation narrative at King George Sound in Western Australia that originated in the early nineteenth century during an era of European exploration when explorers had fleeting meetings with the Mineng. This friendship narrative has been continually re-presented and inscribed by settlers and later by historians without its imperial power dynamic being critiqued. This essay attempts a genealogy of this friendship motif  as well as exploring the destablising of this narrative by writers and community members. This essay also suggests ways of decolonising this narrative and searches for alternative emotions from this frontier.

Tri-component bio-composite materials prepared using an eco-friendly processing route

We report on the blending of three natural polymers, raw cotton, silk and wool, using ionic liquids as the dissolving media. We find that with increased content of wool and silk the thermal degradation temperature of the new bio films increases. This is due to an increase in the hydrogen bond network between the blended polymers. We also investigated the role of the coagulating solvent by coagulating the bio films using water, methanol or isopropanol. Again, we find the coagulating solvent impacts the final properties of the bio films with water shown to coagulated films with the best material properties.

‘Waiting-to-see’ if the baby will come : findings from a qualitative study in Kafa Zone, Ethiopia

Background: Much of the quantitative research on maternal mortality in developing countries focuses on the need for health service interventions such as skilled attendants at birth and emergency obstetric and newborn care. A growing number of studies document the need for a more comprehensive perspective and include the macrostructural, that is, the social, cultural, economic and political determinants of health.
Objectives: To examine the salient aspects of birth at home and variables that influence decision making around transfer to a health facility during prolonged/obstructed labor.
Methods: Ethnography using participant observation and semi-structured interviews was conducted in 2007. A total of 56 mothers in Kafa Zone were selected: 20 in-depth interviews with women who gave birth at home; four who gave birth in a health facility; and 32 during antenatal care. Interviews were also conducted with health staff from Bonga Hospital and 15 health centers or health posts. Analysis followed a process of data reduction, data display and conclusion drawing/verification with the data organized around key themes.
Results: Most women gave birth at home assisted by their neighbor, mother, mother-in-law, or husband. It is likely women who gave birth at home feel ‘safe’ because that is where birth normally takes place and where they feel supported by close relatives and neighbors. Prolonged labor or ‘waiting-to-see’ if the baby would come was somewhat normalized and resulted in considerable delays to seeking assistance. Women felt it was ‘unsafe’ to go to a health facility because of the very real possibility that they would die on the way.
Conclusion: The findings highlight the importance of educating the local communities to recognize pregnancy related risks and to develop and implement appropriate responses, especially early referral, as communities play an important mobilizing role to health services.

Formative evaluation of baby makes 3

Baby Makes 3 was originally developed by Whitehorse Community Health Service and the City of Whitehorse as a program which seeks to prevent violence by promoting respect and equality between couples who have recently become parents for the first time. This is a significant but often stressful event in the life of families and it is not uncommon for couples to adopt ways of relating which reflect gendered norms and foster inequality.
By being offered as a program to all first-time parents by maternal and child health staff, the program in Whitehorse managed to engage with couples at this critical time, many of whom found the program enabled them to adopt greater equality in their relationships. As such, the initial Baby Makes 3 program has been found to be an effective and cost-efficient violence prevention strategy (Flynn, 2011).
The introduction of Baby Makes 3 to the Great South Coast Region is the first time this program has been implemented in a non-metropolitan setting. In addition to the original program aims, a number of additional aims and activities have been added, with the new project being known as Baby Makes 3 Plus.
Programs developed in urban contexts often face different challenges when implemented in rural and regional settings. Likewise, the factors for facilitating success may vary from those in an urban setting (Maidment and Bay, 2012). Hence, this formative evaluation aims to provide feedback on the initial implementation of the original Baby Makes 3 program in the Great South Coast Region with the expectation this will enable problems with implementation and/or opportunities for further enhancement of outcomes to be identified and appropriate action taken.

Knowledge change regarding osteoporosis prevention: translating recommended guidelines into user-friendly messages within a community forum.

Osteoporosis is a skeletal disorder characterised by low bone mineral density and increased fracture risk. Nationally the total costs of this chronic disease are currently estimated at $2.754 billion annually. Effective public health messages providing clear recommendations are vital in supporting prevention efforts. This research aimed to investigate knowledge change associated with the translation of preventive guidelines into accessible messages for the community.

Human passive motions and a user-friendly energy harvesting system

Energy harvesting for wireless sensors and consumer electronic devices can significantly improve reliability and environmental sustainability of the devices. This is achieved by eliminating the dependency of these devices on rechargeable batteries, using clean and/or renewable energy sources. Energy harvesting from various energy sources is widely discussed among researchers and entrepreneurs, including harvesting energy from microscale phenomena. This topic is receiving increasing attention due to the rising numbers of low-power consumer electronic devices and wireless sensors, but also the increasing demand for more convenient and available devices. This article presents a feasibility study for an energy harvesting system based on a human's breathing motion. The system is based on a modified pants belt that is integrated with an array of piezoelectric films and a harvesting circuit. The proposed energy harvester generates electricity from reciprocal abdominal motions of the human subject. In comparison with existing breathing-based energy harvesters, the proposed system allows for safe and convenient energy harvesting with no influence on the natural movement of the lungs. Stomach pressure analysis and measurement, as well as the design and simulations of the proposed harvester, are presented. © 2013 The Author(s).
