Adolescent peer group orientation, parent/attachment styles and mental health

Jennette Robinson’s research examined peer group characteristics and their relationship to parent/peer attachment, parenting styles, and adolescent functioning. Secure parental attachments were not associated with easier group access or participation in a greater number of groups. Evidence supported a relationship between parenting style and both group establishment and membership hierarchy.

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

Senior marketers’ insights into the challenges of social media implementation in large organisations: assessing generic and electronic orientation models as potential solutions

The unique characteristics of social media (SM) have made it difficult to implement this tool within many large organisations. This paper seeks to identify the implementation challenges and evaluate alternative organisational orientations that may provide solutions. We aimed to reconcile theory with current practice by integrating the extant literature with data from three focus groups involving 27 senior marketing executives. The managerial discussions identified additional challenges to those previously discussed in the literature, which appear to result from SM’s unique characteristics. These include: interactivity, the integration of communication into distribution channels, collaborative media and information collection. Using both broad orientation models (market orientation and entrepreneurial orientation) and a specific digital orientation (e-marketing orientation), guidelines and research propositions for effective implementation are put forward.

Effect of feed temperature and membrane orientation on pre-treatment sludge volume reduction through forward osmosis

This study focuses on volume reduction of pre-treatment sludge as well as on dilution of reverse osmosis (RO) concentrate through emerging forward osmosis (FO) technology where RO concentrate draws water from the pre-treatment sludge (feed solution) in order to reduce pre-treatment sludge volume and increase the RO water recovery. Experiments were carried out using two different types of sludge i.e. (1) synthetic pre-treatment sludge (Lab sludge) which has lower salinity and (2) actual sludge from Perth Seawater Desalination Plant, Australia (Perth Seawater Desalination Plant (PSDP) sludge) which has higher salinity. Effect of membrane orientation (FO and pressure-retarded osmosis (PRO) modes) and temperature of pre-treatment sludge on permeate water flux was investigated. There was a significant increase in water flux from 3.2 to 10.2 LMH (i.e. ~3 times higher) when temperature increased from 20 to 40°C for Lab sludge in PRO mode. However, there is no significant effect of temperature on water flux in FO mode for Lab sludge. On the contrary for PSPD sludge, there was no effect on water flux with increase in temperature at PRO mode. Dissolved ions in the porous side increased the severity of concentrative internal concentration polarization; hence, it could reduce the flux. There was no significant change in water flux when temperature increased from 20 to 40°C for PSDP sludge in FO mode. However, higher amount of water has permeated from Lab sludge compared to PSDP sludge in FO mode. © 2014 © 2014 Balaban Desalination Publications. All rights reserved.

The National Safety and Quality Health Service Standards requirements for orientation and induction within Australian healthcare: a review of the literature

Introduction: A workplace orientation program is a core requirement of the National Safety and Quality Health Service (NSQHS) Standards in Australia. This is particularly important within healthcare as patient safety and the patient experience are at risk if the healthcare workforce is not supported with an effective orientation and induction program. Aim: This study aimed to review the literature and map the requirements of the NSQHS Standards in relation to orientation and induction. Method: This study utilised online databases to search for literature pertaining to orientation and induction within healthcare. Inclusion criteria included relevance to research questions, and originating in a country with a comparative health system to Australia. Results: The search identified a total of 202 articles of potential relevance with 42 articles meeting the inclusion criteria. Articles were ranked according to hierarchy of evidence criteria for both qualitative and quantitative studies. The importance of using orientation to detail safety and quality roles, the organisations' risk management system, governance structure, operational processes and procedures was highlighted. Patient-centred care, antimicrobial stewardship, clinical handover and mechanisms for escalation of care and emergency assistance should also be covered within the orientation process. Conclusion: There is a dearth of studies in relation to orientation and induction in the healthcare literature. Orientation content is now clearly prescribed, what is lacking within healthcare is a standardised framework. Concept mapping, educational theory and adult learning methods have been shown to enhance workforce problem solving and engagement with orientation, however further research is needed to enhance practice

Influence of orientation on twin nucleation and growth at low strains in a magnesium alloy

The resolved shear stress is believed to play an important role in twin formation. The present study tests this idea for an extruded magnesium alloy by examining "tension" twinning in different grain orientations. Electron backscatter diffraction analysis is employed for alloy AZ31 tested in compression along the extrusion axis to strains between 0.008 and 0.015. For heavily twinned grains, it is seen that twinning occurs on 2.3 twin systems per grain on average. The active systems are also most commonly those with, or very near to, the highest Schmid factor. The most active system in multiply twinned grains accounts on average for ∼0.6 of the twinning events. In addition, it is found that the twin habit plane falls within 6° of the K1 plane. Orientations with the highest Schmid factors (0.45-0.5) for twinning display twin aspect ratios greater by ∼40% and twin number densities greater by ∼10 times than orientations with maximum Schmid factors for twinning of 0.15-0.2. Thus the Schmid factor for twinning is seen to affect nucleation more than thickening in the present material. Viscoplastic crystal plasticity simulations are employed to obtain approximations for the resolved shear stress. Both the twin aspect ratio and number density correlate quite well with this term. The effect of the former can be assumed to be linear and that of the latter follows a power law with exponent ∼13. Increased aspect ratios and number densities are seen at low Schmid factors and this may relate to stress fluctuations, caused most probably in the present material by the stress fields at the tips of blocked twins. Overall, it is evident that the dominance of twinning on high Schmid factor systems is preserved at the low strains examined in the present work, despite the stress fluctuations known to be present. © 2014 Acta Materialia Inc.

Automated quantification of neurite outgrowth orientation distributions on patterned surfaces

Objective. We have developed an image analysis methodology for quantifying the anisotropy of neuronal projections on patterned substrates. Approach. Our method is based on the fitting of smoothing splines to the digital traces produced using a non-maximum suppression technique. This enables precise estimates of the local tangents uniformly along the neurite length, and leads to unbiased orientation distributions suitable for objectively assessing the anisotropy induced by tailored surfaces. Main results. In our application, we demonstrate that carbon nanotubes arrayed in parallel bundles over gold surfaces induce a considerable neurite anisotropy; a result which is relevant for regenerative medicine. Significance. Our pipeline is generally applicable to the study of fibrous materials on 2D surfaces and should also find applications in the study of DNA, microtubules, and other polymeric materials.

Entrepreneurial orientation and performance of microenterprises in an emerging economy

Guided by the literature on institutional theory and entrepreneurial orientation (EO), this study examines the impact of the institutional environment on EO and performance of microenterprises at the subnational, city level in an emerging economy in contrast to most studies conducted at the national level in developed markets. The results of the study show that four types of formal institutions and two types of informal institutions are significantly associated with EO and that the latter is positively associated with higher levels of microenterprise performance. Implications of the results and future research directions are discussed.

Asian Cities: Cultural heritage and the interplay between nation building and internationalism

It is over a decade since the volume The Disappearing Asian City (Logan 2002) was published. An edited volume bringing together a number of experts on the region, the book identified the threats facing buildings, archaeological sites and the historic character of cities, as well as the myriad of challenges of raising civic and regulatory awareness about the value of cultural heritage in times of rapid transformation. It was a set of concerns and arguments that remain as pertinent as ever. Those who have lived and worked in different parts of Asia over the past decade on cultural heritage issues, frequently use the terms 'extraordinary' or 'bewildering' to describe the scale and speed of transformation that has taken place. Indeed, for those concerned about maintaining continuities between past and present - whether they be social, spiritual or material - the development of cities, the wholesale movements of communities in and out of urban landscapes, together with the dramatic increase in industries like tourism, has often been disorienting, and in some cases deeply confronting: both professionally and emotionally. And yet, to focus on loss and destruction would miss a whole set of other fascinating, emergent and important trends. As numerous publications in the intervening period have shown, cultural heritage has become a topic of intense interest and debate in the majority of Asian societies, for a host of reasons (Askew 2010; Broudehoux 2004; Pai 2013).

Sexual orientation and psychological distress: the role of minority stress

 The thesis found that that personal homonegativity/binegativity and discrimination are important when considering risk for depression and anxiety in gay men, lesbian women, bisexual men and bisexual women. The thesis also highlights the important role intrapersonal resilience can have in partially protecting sexual minority groups against these stressors.

Homeland, territory, property: contesting land, state, and nation in urban Timor-Leste

This article considers contestations over land, state and nation in Aitarak Laran, an urban settlement in post-independence Timor-Leste. Since 2010 the settlement has been resisting eviction by the East Timorese state, which wishes to use the land it occupies to build a National Library and Cultural Centre. In exploring the contestation, the purpose of this article is two-fold. Firstly, it explores the nature of social connection to land within postcolonial state- and nation-building. Here, the contestation at Aitarak Laran reveals counter-posed imaginings of land as homeland, territory and property. Secondly, the article draws out the implications of these counter-posed imaginings for thinking about the 'right to the city', a notion first theorised by Lefebvre (1996 [1968]) and subsequently developed to encompass a range of modes of urban protest. In the settlement, the promises of independence-unity, equivalence, and inclusion within the sovereign nation-state-are at odds with residents' experiences of what independence has in fact brought. Land, in its multiple imaginings, becomes a crucible upon which this painful disjuncture plays out. Reading Aitarak Laran as an instance of 'right to the city' struggle, these tensions emerge as well not only in practice but also in theory, reflected particularly in the limitations and ambiguities of rights discourse.
