Destination Australia: Working conditions of Korean women working in the entertainment and sex industry
The experience of women working in the sex and entertainment industry is an issue central to feminism, social and human rights movements, and ongoing political debate. Although now an area of scholarly research the clandestine nature of this industry makes research challenging and means many aspects remain unknown. In this paper, the researchers examine the working conditions of Korean women working in the sex industry in Australia. The paper reports on recent trends in patterns of migration and draws attention to the fact that increasing numbers of Korean women are utilising =working holiday` visas to work in the sex and entertainment industry and that under Australian law this practice is essentially legal. The paper also examines the nature of their service in the sex industry and details the conditions of their employment. Findings from this study aim to inform recommendations to policy makers in relevant government and non-government community service organisations
Is alveolar ridge preservation an overtreatment?
The morphology and dimensions of the postextraction alveolar ridge are important for the surgical and restorative phases of implant treatment. Adequate new bone formation and preservation of alveolar ridge dimensions following extraction will facilitate installation of the implant in a restorative position, while preservation of soft tissue contour and volume is essential for an aesthetic and implant-supported restoration with healthy peri-implant tissues. Alveolar ridge preservation (ARP) refers to any procedure that aims to: (i) limit dimensional changes in the alveolar ridge after extraction facilitating implant placement without additional extensive bone and soft tissue augmentation procedures (ii) promote new bone formation in the healing alveolus, and (iii) promote soft tissue healing at the entrance of the alveolus and preserve the alveolar ridge contour. Although ARP is a clinically validated and safe approach, in certain clinical scenarios, the additional clinical benefit of ARP over unassisted socket healing has been debated and it appears that for some clinicians may represent an overtreatment. The aim of this critical review was to discuss the evidence pertaining to the four key objectives of ARP and to determine where ARP can lead to favorable outcomes when compared to unassisted socket healing
Air-spun PLA nanofibers modified with reductively-sheddable hydrophilic surfaces for vascular tissue engineering : synthesis and surface modification
Polylactide (PLA) is a class of promising biomaterials that hold great promise for various biological and biomedical applications, particularly in the field of vascular tissue engineering where it can be used as a fibrous mesh to coat the inside of vascular prostheses. However, its hydrophobic surface providing nonspecific interactions and its limited ability to further modifications are challenges that need to be overcome. Here, the development of new air-spun PLA nanofibers modified with hydrophilic surfaces exhibiting reduction response is reported. Surface-initiated atom transfer radical polymerization allows for grafting pendant oligo(ethylene oxide)-containing polymethacrylate (POEOMA) from PLA air-spun fibers labeled with disulfide linkages. The resulting PLA-ss-POEOMA fibers exhibit enhanced thermal stability and improved surface properties, as well as thiol-responsive shedding of hydrophilic POEOMA by the cleavage of its disulfide linkages in response to reductive reactions, thus tuning the surface properties
Classification of facial periâ implant soft tissue dehiscence/deficiencies at single implant sites in the esthetic zone
BackgroundThe incidence of a periâ implant soft tissue dehiscence/deficiency (PSTD) is not a rare finding. Despite multiple previous attempts aimed at correcting the PSTDs, a classification of these conditions has not yet been proposed. This lack in the literature may also lead to discrepancies in the reported treatment outcomes and thus misinform the clinician or the readers. The aim of the present article was therefore to present a classification of periâ implant PSTD at a single implant site.MethodsFour classes of PSTDs were discussed based on the position of the gingival margin of the implantâ supported crown in relation to the homologous natural tooth. In addition, the buccoâ lingual position of the implant head was also taken into consideration. Each class was further subdivided based on the height of the anatomical papillae.ResultsSubsequently, for each respective category a surgical approach (including bilaminar techniques, the combined prostheticâ surgical approach or soft tissue augmentation with a submerged healing) was also suggested.ConclusionThis paper provides a new classification system for describing PSTDs at single implant sites, with the appropriate recommended treatment protocol.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/151905/1/jper10351_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/151905/2/jper10351.pd

In vitro antioxidant properties of a ginseng intestinal metabolite IH-901
IH-901 (20-O-β-D-glucopyranosyl-20(S)-protopanaxadiol or compound K) is a final intestinal bacterial metabolite of ginseng in humans. It has various pharmacologic effects such as antiaging, immunopotentiation, antistress, and antimetastatic activities. We analyzed the antioxidant activities of IH-901 using several assays including: total antioxidant activity, reductive potential, 1,1-diphenyl-2-picryl-hydrazyl, hydroxyl, superoxide and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging assays, a nitric oxide scavenging assay and a lipid peroxidation assay. At concentrations of 25 and 100 µg/mL, IH-901 inhibited lipid peroxidation of a linoleic acid emulsion with a potency comparable to ascorbic acid and butylated hydroxyanisole. The reductive potential of IH-901 increased in a concentration-dependent manner. IH-901 exhibited strong DPPH, hydroxyl, superoxide and ABTS radical scavenging activities. IH-901 was also an effective inhibitor of lipid peroxidation, although IH-901 had only a mild scavenging activity against nitric oxide. These results suggest that IH-901 may be a useful antioxidant agent against reactive oxygen species
Integrating the promotion of physical activity within a smoking cessation programme: Findings from collaborative action research in UK Stop Smoking Services
Background: Within the framework of collaborative action research, the aim was to explore the feasibility of
developing and embedding physical activity promotion as a smoking cessation aid within UK 6/7-week National
Health Service (NHS) Stop Smoking Services.
Methods: In Phase 1 three initial cycles of collaborative action research (observation, reflection, planning,
implementation and re-evaluation), in an urban Stop Smoking Service, led to the development of an integrated
intervention in which physical activity was promoted as a cessation aid, with the support of a theoretically based
self-help guide, and self monitoring using pedometers. In Phase 2 advisors underwent training and offered the
intervention, and changes in physical activity promoting behaviour and beliefs were monitored. Also, changes in
clients’ stage of readiness to use physical activity as a cessation aid, physical activity beliefs and behaviour and
physical activity levels were assessed, among those who attended the clinic at 4-week post-quit. Qualitative data
were collected, in the form of clinic observation, informal interviews with advisors and field notes.
Results: The integrated intervention emerged through cycles of collaboration as something quite different to
previous practice. Based on field notes, there were many positive elements associated with the integrated
intervention in Phase 2. Self-reported advisors’ physical activity promoting behaviour increased as a result of
training and adapting to the intervention. There was a significant advancement in clients’ stage of readiness to use physical activity as a smoking cessation aid.
Conclusions: Collaboration with advisors was key in ensuring that a feasible intervention was developed as an aid to smoking cessation. There is scope to further develop tailored support to increasing physical activity and
smoking cessation, mediated through changes in perceptions about the benefits of, and confidence to do physical activity
ABCD Neurocognitive Prediction Challenge 2019: Predicting individual residual fluid intelligence scores from cortical grey matter morphology
We predicted residual fluid intelligence scores from T1-weighted MRI data
available as part of the ABCD NP Challenge 2019, using morphological similarity
of grey-matter regions across the cortex. Individual structural covariance
networks (SCN) were abstracted into graph-theory metrics averaged over nodes
across the brain and in data-driven communities/modules. Metrics included
degree, path length, clustering coefficient, centrality, rich club coefficient,
and small-worldness. These features derived from the training set were used to
build various regression models for predicting residual fluid intelligence
scores, with performance evaluated both using cross-validation within the
training set and using the held-out validation set. Our predictions on the test
set were generated with a support vector regression model trained on the
training set. We found minimal improvement over predicting a zero residual
fluid intelligence score across the sample population, implying that structural
covariance networks calculated from T1-weighted MR imaging data provide little
information about residual fluid intelligence.Comment: 8 pages plus references, 3 figures, 2 tables. Submission to the ABCD

A cross validation of Consumer-Based Brand Equity (CBBE) with Private Labels in Spain
Molinillo,S., Ekinci, Y., Japutra, A. (2014)'A cross validation of Consumer-Based Brand Equity (CBBE) with Private Labels in Spain'. in MartĂnez-LĂłpez, Gázquez-Abad, J.C. and Sethuraman, R. J.A. (eds.) Advances in National Brand and Private Label Marketing. Second International Conference, 2015. Springer Proceedings in Business and Economics, pp. 113-125In recent years a number of Consumer-Based Brand Equity (CBBE) models and measurement scales have been introduced in the branding literature. However, examinations of brand equity in Private Labels (PL) are rather limited. This study aims to compare the validity of the two prominent CBBE models those introduced by Yoo and Donthu (2001) and Nam et al. (2011). In order to test the models and make this comparison, the study collected data from 236 respondents who rated private labels in Spain. A list of 30 different fashion and sportswear PL was introduced to respondents. These brands do not make any reference to the retail store in which they are sold. Research findings suggest that the extended CBBE model introduced by Nam et al. (2011) and Ciftci et al. (2014) is more reliable and valid than Yoo and Donthu’s model for assessing PL. Theoretical contributions and managerial implications are discussed.Universidad de Málaga. Campus de Excelencia Internacional AndalucĂa Tech
