title: Comparison of blended elemental (BE) and mechanical alloyed (MA) powder compact forging into Ti-6Al-4V rocker arms

authors: Jia, Mingtu

subjects: Powder compact forging

abstract: Ti-6Al-4V rocker arms for internal combustion engines were produced by forging of compacts of blended powder consisting of elemental hydride-dehydride (HDH) titanium powder and Al60V40 (wt%) master alloy powder or mechanical alloyed (MA) powder synthesized by high energy mechanical milling of a mixture of HDH titanium and Al60V40 master alloy powders. The powder compacts were made by warm compaction, and their relative density was 90%. The mechanical properties and microstructures of as-forged parts made using blended powder were improved significantly with increasing holding time at forging temperature, and close to those of as-forged parts produced by powder compact forging of HDH Ti-6Al-4V pre-alloyed powder. However, the as-forged part produced by powder compact forging of MA powder was brittle, and fractured prematurely during tensile testing.

title: Experiences of women returning to work after maternity leave

authors: Sriram, Divya

subjects: maternity leave

abstract: With an increase in the number of women in the workforce, numerous studies have looked at the importance of parental leave and benefits of cash, predictors of postpartum depression, and how they affect women, handling work-family conflict, family friendly policies and many more. Of particular interest for many working women is research looking at working mothers and the issues that have an impact on mothers. Longer duration of leave has been shown to have numerous physical and mental health benefits for the mother and the child, such as mother-infant attachment. Similarly, workplace support and work-life balance were found beneficial for working mothers. This study investigates factors such as work-life balance, social support, length of maternity leave and mental health. It explores both the positive and negative impacts these factors have on mothers and their babies once mothers return to work. The study used a qualitative methodology, interviewing 11 working mothers. The participants had returned to work within the last three years, some as recent as four weeks, at the time of the interview. Participants had at least one child under the age of four. The sample of working mothers included most of the mothers working full-time, some working part-time and one mother working as self-employed. Template analysis was used to analyze the interview transcripts. Analysis revealed that working mothers returned to work for myriad reasons after having been on government aided maternity leave. Work-life balance policies like reduced hours and returning part-time initially for some mothers were found along with an understanding supervisor and supportive colleagues. In conclusion, working mothers desired longer leave citing their need to bond with the baby as one of the reason. Mothers had satisfactory support from family, friends and workplace. In addition to the government mandated parental leave policies, working mothers found a lack of information on any additional policies offered by their organizations and preferred more communication on them.

title: Research support in New Zealand University Libraries

authors: Howie, Jess

abstract: Researcher-facing librarians in New Zealand are providing guidance across more of the research lifecycle than ever before in response to an increasingly complex scholarly ecosystem. This research explored the development of research support through survey responses from all eight New Zealand University Libraries. From the responses it was possible to ascertain the level of services offered or planned in the four key areas of research impact, Research Data Management, scholarly communication and Kaupapa Māori research. Skills gaps and barriers to service development were also identified. Comparison with an earlier study revealed that research impact and Research Data Management services have developed well over the last 6 years. A good level of maturity was identified in scholarly communication services but support for Kaupapa Māori research was identified as an area for development. Barriers to service development included lack of resourcing and low recognition of library value from the wider institution.
