Bramstedt, Katrina A. "Increasing Donation Opportunities for Vascularized Composite Allografts". Progress in Transplantation 26, n.º 4 (20 de agosto de 2016): 372–77. http://dx.doi.org/10.1177/1526924816664080.
Texto completo da fonteResumo:
There are 40 vascularized composite allotransplant programs across 5 continents served by 31 organ procurement organizations (or equivalent). The organizations’ websites inform about organ and tissue donation. This research explored worldwide educational efforts on vascularized composite allograft (VCAG) donation via their corporate websites as well as options within donor registries and donor card systems to indicate a VCAG donation preference. Of these, 13 (41.9%) of 31 had VCAG content and 7 (22.6%) of 31 offered a mechanism for individuals to voice a preference about VCAG donation through an opt in donor registry or card or an opt out registry. In North America, the only donor registration/card system that facilitated VCAG donation is in Mexico. The resistance to consent for VACG donation is likely due to poor public education and the personal nature of face, hand, uterus, and penile allografts. Efforts to reduce this resistance can begin with the assistance of website content, registries, and donor cards.

"Transmission of Grapevine Red Blotch Virus by Spissistilus festinus [Say, 1830] (Hemiptera: Membracidae) between Free-Living Vines and Vitis vinifera ‘Cabernet Franc’".

Texto completo da fonteResumo:
Grapevine red blotch disease emerged within the past decade, disrupting North American vine stock production and vineyard profitability. Our understanding of how grapevine red blotch virus (GRBV), the causal agent of the disease, interacts with its Vitis hosts and insect vector, Spissistilus festinus, is limited. Here, we studied the capabilities of S. festinus to transmit GRBV from and to free-living vines, identified as first-generation hybrids of V. californica and V. vinifera ‘Sauvignon blanc’ (Vcal hybrids), and to and from V. vinifera ‘Cabernet franc’ (Vvin Cf) vines. The transmission rate of GRBV was high from infected Vcal hybrid vines to healthy Vcal hybrid vines (77%, 10 of 13) and from infected Vvin Cf vines to healthy Vcal hybrid vines (100%, 3 of 3). In contrast, the transmission rate of GRBV was low from infected Vcal hybrid vines to healthy Vvin Cf vines (15%, 2 of 13), and from infected Vvin Cf vines to healthy Vvin Cf vines (19%, 5 of 27). No association was found between transmission rates and GRBV titer in donor vines used in transmission assays, but the virus titer was higher in the recipient leaves of Vcal hybrid vines compared with recipient leaves of Vvin Cf vines. The transmission of GRBV from infected Vcal hybrid vines was also determined to be trans-stadial. Altogether, our findings revealed that free-living vines can be a source for the GRBV inoculum that is transmissible by S. festinus to other free-living vines and a wine grape cultivar, illustrating the interconnected roles of the two virus hosts in riparian areas and commercial vineyards, respectively, for virus spread. These new insights into red blotch disease epidemiology will inform the implementation of disease management strategies.

Texto completo da fonteResumo:
The Victorian Certificate of Applied Learning (VCAL) is a very successful senior secondary school qualification introduced in the Australian state of Victoria in 2002. Applied learning in the VCAL engages senior students in a combination of work-based learning, service-learning, and project-based learning and aims to provide them with the skills, knowledge, and attitudes to make informed choices regarding pathways to work and further education. The program has enjoyed rapid growth and its system-wide adoption by Victorian secondary schools, Technical and Further Education (TAFE) institutions, Registered Training Organizations (RTOs), and Adult and Community Education (ACE) providers has broadened significantly the range of senior schooling pathway options for young people. This paper will examine reasons for developing an applied learning senior secondary certificate and its rapid growth in Victoria since 2002. The authors draw on a number of case studies to profile the unique nature of applied learning in the VCAL, including its dimensions of service learning, work-based learning, and project-based learning. These case studies are also used to discuss a number of implications that have emerged from the use of applied learning in the VCAL, including approaches to teaching and assessment that will support applied learning and the development of new partnerships between VCAL providers and community partners. Finally, the paper considers significant implications the VCAL has created for teacher education in Victoria by discussing the new Graduate Diploma of Education (Applied Learning) developed by Deakin University.

Texto completo da fonteResumo:
The aim of this review was to give an overview of the outcomes of the use of different regenerative materials to treat molars with class II furcation defects in patients with periodontitis in comparison with open flap debridement (OFD). A search of five databases (PubMed-Medline, Embase, Cochrane, Scopus and Web of Science) was conducted up to and including January 2022. According to the PICOS guidelines, only randomized control trials (S) considering periodontal patients with at least one molar with a class II furcation involvement (P) treated with regenerative materials (I) in comparison to OFD as control treatment (C) and a minimum follow-up period of 6 months were included. Vertical clinical attachment level (VCAL) was considered as the primary outcome (O), while horizontal clinical attachment level (HCAL), horizontal probing depth (HPD) and vertical probing depth (VPD) were considered as secondary outcomes. The search through the databases initially identified 1315 articles. Only 25 of them met the eligibility criteria and were included. The studies were grouped in four macro-categories according to the material used: absorbable and non-absorbable membranes, blood derivatives and a combination of different materials. The greater part of the included studies reported a statistically significant difference in using regenerative materials when compared to OFD. The blood derivatives groups reported a range of mean changes in VCAL of 0.86–4.6 mm, absorbable membrane groups reported −0.6–3.75 mm, non-absorbable membranes groups reported −2.47–4.1 mm, multiple materials groups reported −1.5–4.87 mm and enamel matrix derivatives reported a mean change in VCAL of 1.45 mm. OFD showed a range of mean VCAL changes of −1.86–2.81 mm. Although no statistical analysis was performed, the use of regenerative materials may be considered moderately beneficial in the treatment of molars with grade II furcation involvement. However, the substantial heterogeneity in the protocols’ design does not allow us to draw definitive conclusions. In addition, low levels of evidence for morbidity and patient-centered outcomes were reported.

Texto completo da fonteResumo:
The purpose of the article was to compare selected calculation methods regarding shear strength in reinforced concrete beams without web reinforcement. Several calculation methods were tested. This included codes: PN-EN 1992-1-1:2008, ACI 318-14 and fib Model Code for Concrete Structures 2010. The analysis also consists of authorial methods published in technical literature. Calculations of shear strengths were made based on experimental works found in literature. The shear strength ratios Vtest/Vcalc were chosen to be the yardstick of comparison, where Vtest is the experimental shear strength and Vcalc is the calculated shear strength. A wide range of variables including shear span/depth ratio, compressive strength of concrete, longitudinal steel percentage helped to verify the applicability of calculation methods. Although most of authorial techniques proved to be unstable, they succeeded to show that codes’ formulas for shear strength may still be improved. The presented article is a part of Authors’ long term research in the matter and a new chapter of their study now concerning beams without web reinforcement.

"Use of Platelet-Rich Fibrin in the Treatment of Grade 2 Furcation Defects: Systematic Review and Meta-Analysis". Journal of Clinical Medicine 9, n.º 7 (3 de julho de 2020): 2104. http://dx.doi.org/10.3390/jcm9072104.
Texto completo da fonteResumo:
In periodontitis patients, furcation defects are crucial sites to regenerate due to their complex anatomy. Various modern surgical techniques and use of biomaterials have been suggested in the literature. Among all, platelet-rich fibrin (PRF) has potential in tissue regeneration thanks to its role in the release of growth factors. Therefore, the purpose of this study was to evaluate the beneficial effect of the addition of PRF to open flap debridement (OFD) or as an adjuvant to other biomaterials such as bone grafts in the treatment of grade 2 mandibular furcation defects. Systematic research was carried out on the databases Medline, Scopus, Embase, and Cochrane Library and registered on PROSPERO (CRD42020167662). According to the PICO guidelines by Cochrane, randomized trials and prospective non-randomized trials were evaluated, with a minimum follow-up period of 6 months. The inclusion criteria were the absence of systemic diseases, non-smoking patients, and a population aged from 18 to 65 years. Vertical pocket probing depth (PPD), vertical clinical attachment level (VCAL), and gingival recession (REC) were the primary outcomes. Vertical furcation depth (VFD), and the percentage of bone defect fill (%v-BDF) were considered as secondary outcomes. A meta-analysis of the primary and secondary outcomes was performed. Publication bias was assessed through a funnel plot. Eighty-four articles were initially extracted. Eight randomized clinical trials were analyzed according to the exclusion and inclusion criteria. The Quality assessment instrument (QAI) revealed four articles at low risk of bias, one at moderate, and three at high risk of bias. The metanalysis showed significant data regarding PPD, VCAL, VFD and %v-BDF in the comparison between PRF + OFD vs. OFD alone. The adjunct of PRF to a bone graft showed a significant difference for VCAL and a not statistically significant result for the other involved parameters. In conclusion, the adjunctive use of PRF to OFD seems to enhance the periodontal regeneration in the treatment of grade 2 furcation defects. The combination of PRF and bone graft did not show better clinical results, except for VCAL, although the amount of literature with low risk of bias is scarce. Further well-designed studies to evaluate the combination of these two materials are therefore needed.

Texto completo da fonteResumo:
AbstractOne hundred and fifty-seven students (aged 15 to 19 years) enrolled in the Victorian Certificate of Applied Learning (VCAL) program completed the Adolescent Coping Scale (ACS), and measures of school-related stress, attitudes to school and wellbeing. In general, VCAL students reported a positive attitude to school, high levels of wellbeing, low levels of school-related stress, and used a wide range of coping strategies. Gender differences and attitudinal differences were found in relation to coping strategies used, wellbeing, and stress. Discriminant analysis indicated that for females, low levels of school-related stress and frequent use of the ‘work hard’coping strategy significantly predicted a positive attitude to school, while for males high levels of wellbeing, and the frequent use of ‘work hard’, ‘focus on the positive’, and minimal use of ‘tension reduction’ predicted positive attitudes to school. The findings are discussed in light of current research and recommendations for interventions are proposed.

Texto completo da fonteResumo:
The traditional method for power load forecasting is susceptible to various factors, including holidays, seasonal variations, weather conditions, and more. These factors make it challenging to ensure the accuracy of forecasting results. Additionally, there is a limitation in extracting meaningful physical signs from power data, which ultimately reduces prediction accuracy. This paper aims to address these issues by introducing a novel approach called VCAG (Variable Mode Decomposition—Convolutional Neural Network—Attention Mechanism—Gated Recurrent Unit) for combined power load forecasting. In this approach, we integrate Variable Mode Decomposition (VMD) with Convolutional Neural Network (CNN). VMD is employed to decompose power load data, extracting valuable time-frequency features from each component. These features then serve as input for the CNN. Subsequently, an attention mechanism is applied to give importance to specific features generated by the CNN, enhancing the weight of crucial information. Finally, the weighted features are fed into a Gated Recurrent Unit (GRU) network for time series modeling, ultimately yielding accurate load forecasting results.To validate the effectiveness of our proposed model, we conducted experiments using two publicly available datasets. The results of these experiments demonstrate that our VCAG method achieves high accuracy and stability in power load forecasting, effectively overcoming the limitations associated with traditional forecasting techniques. As a result, this approach holds significant promise for broad applications in the field of power load forecasting.

Journal of Cognitive Neuroscience 14, n.º 2 (1 de fevereiro de 2002): 298–310. http://dx.doi.org/10.1162/089892902317236911.
Texto completo da fonteResumo:
The basal ganglia are intimately connected to the frontal cortex via five fronto-striatal circuits. While the role of the frontal cortex in cognition has been extensively studied, the contribution of the basal ganglia to cognition has remained less clear. In Parkinson's disease, posteroventral pallidotomy (PVP) involves surgical lesioning of the internal section of the globus pallidus (GPi, the final output pathway from the basal ganglia) to relieve the motor symptoms of the disorder. PVP in Parkinson's disease provides a unique opportunity to investigate the impact of disruption of striatal outflow to the frontal cortex on cognition. We assessed executive function and working memory after withdrawal of medication in 13 patients with Parkinson's disease before and 3 months after unilateral PVP compared to 12 age-and IQ-matched normals assessed twice with an interval of 3 months. The tests used were: Wisconsin Card Sorting (WCST), Self-Ordered Random Number Sequences, Missing Digit Test, Paced Visual Serial Addition Test (PVSAT), and Visual Conditional Associative Learning Test (VCALT). After PVP, the patients performed significantly better on the Self-Ordered Random Number Sequences and the WCST, an improvement that was also observed in the normals across the two assessment and is therefore likely to reflect practice effects. Relative to the normals, the patients showed significant differential change following PVP on the Missing Digit Test and PVSAT, on which they performed worse after compared to before surgery, while the controls performed better on the second assessment. For the patients, performance on the VCALT also indicated deterioration after PVP, but the changes approached significance. The side of PVP had no effect on the results. The pattern of change observed 3 months after PVP was maintained at 15-month follow-up. The results suggest that striatal outflow to the frontal cortex may be essential for those aspects of executive function that showed deterioration after PVP. &

Texto completo da fonteResumo:
In Victoria, there are some school students who, having completed Year 11, as Victorian Certificate of Applied Learning (VCAL) Intermediate students, leave school. They do not go on to complete Year 12 [or equivalent] either in other institutions or as part of an apprenticeship or traineeship. This group of students is quite a substantial proportion of the total VCAL student cohort, and their numbers are increasing every year. This behaviour is juxtaposed with government policy that is emphasizing youth participation in schools or vocational alternatives. The Compact with Young Australians (COAG, 2009) set a new target of 90% attainment of Year 12 or equivalent by 2015 and expects an additional 92,527 young people across Australia (23,500 in Victoria) to remain in school. A survey of the literature indicates that there is a significant gap in our knowledge of what behavioural intentions drive vocational students to leave school early. By using in-depth conversations with selected students, this study seeks to determine the factors that students see act as drivers in their decision to get to this level, and then to leave school. This study provides, in the words of the students, some of the reasons for their choice for their non-continuance of the secondary school programs that are available to them. This will enable education policy makers to understand these students’ perspectives and to examine the VCAL programs in a new light. As educators, they can then respond to the challenge to develop and sustain vocational programs and retention strategies that will engage young people and assist them to build work-ready skills.Master of Business (Research)

van, Son Adriana Johanna Maria. "Beyond the boundary: A three-way partnership creating valuable learning experiences for young people in senior secondary education". Thesis, 2016. https://vuir.vu.edu.au/32592/.
Texto completo da fonteResumo:
While Australia has experienced a steady increase in the proportion of young people who complete their Senior Secondary Certificate there is still a large number of young people who leave school prior to completion (ABS 2015).
To support Year 12 attainment, various policy, programming and curriculum initiatives have been implemented. Relevant for this thesis are the National Partnerships policies that mandate and support school participation, the introduction of the Victorian Certificate of Applied Learning (VCAL) and the proliferation of Flexible Learning Programs (FLPs). Each of these policies and initiatives provide the current education context for the Cricket Victoria Sports Development Program (CV-SDP). The program is designed along applied learning principles to reengage young people with learning who might otherwise have left school without completing Year 12.
The research set out to investigate the learning experiences and education outcomes valued by students in this program which is delivered in the state of Victoria, Australia, in partnership between SEDA, a provider of senior secondary programs, and Cricket Victoria (CV) the peak body for cricket in Victoria. The research also considered how the SEDA-CV partnership contributed to these learning experiences and education outcomes.
The research was conducted using a single case study methodology. Data was gathered using student videos and interviews, senior staff and program staff interviews from SEDA and CV and organisational documents. The data identified two key findings. The first highlights interest-based learning, choice and autonomy as unique features of learning valued by the students.
Secondly, the research reconceptualises educational partnerships beyond the philanthropic relationships currently described in the literature to one of joint value creation (Austin & Seitanidi 2012) where SEDA and CV demonstrate a genuine ability to create value for themselves and each other. Beyond philanthropic, the research also reframes educational partnerships as a three-way partnership that valued young people for their unique contribution, and in exchange provided them with valued learning experiences and education outcomes.
