Factors related to the presentation of thin and thick nodular melanoma from a population-based cancer registry in Queensland Australia

Purpose: Worldwide, the incidence of thick melanoma has not declined, and the nodular melanoma (NM) subtype accounts for nearly 40% of newly-diagnosed thick melanoma. To assess differences between patients with thin (≤2.00 mm) and thick (≥2.01 mm) nodular melanoma, we evaluated factors such as demographics, melanoma detection patterns, tumor visibility, and physician screening for NM alone and compared clinical presentation and anatomic location of NM with superficial spreading melanoma (SSM). Methods We utilized data from a large population-based study of Queensland (Australia) residents diagnosed with melanoma. Queensland residents aged 20 to 75 years with histologically confirmed first primary invasive cutaneous melanoma were eligible for the study, and all questionnaires were conducted by telephone (response rate 77.9%). Results During this four-year period, 369 patients with nodular melanoma were interviewed, of whom 56.7% were diagnosed with tumors ≤ 2.00 mm. Men, older individuals, and those who had not been screened by a physician in the past three years were more likely to have nodular tumors of greater thickness. Thickest nodular melanoma (4 mm+) was also most common in persons who had not been screened by a doctor within the past three years (OR 3.75; 95% CI 1.47-9.59). Forty-six percent of patients with thin nodular melanoma (≤ 2.00 mm) reported a change in color, compared with 64% of patients with thin SSM and 26% of patients with thick nodular melanoma (>2.00 mm). Conclusion Awareness of factors related to earlier detection of potentially fatal nodular melanomas, including the benefits of a physician examination, should be useful in enhancing public and professional education strategies. Particular awareness of clinical warning signs associated with thin nodular melanoma should allow for more prompt diagnosis and treatment of this subtype.

Queensland College of Teachers annual lecture 2010 : child protection

Teachers have a crucial role as “sentinels” for children who have been abused or neglected. This professional development session will provide a framework for understanding the types, incidence and causes of child abuse and neglect, and teachers’ role in reporting suspected cases. The session will provide participants with knowledge and skills to enable them to identify warning signs and indicators of child abuse and neglect, know the basis of their duties to report suspected cases of abuse and neglect, and respond to the needs of abused and neglected children at school. The presentation will focus on: • the reasons why child abuse and neglect can occur; • the different types of child abuse and neglect and their effects on children; • the warning signs and indicators of physical abuse, emotional abuse, sexual abuse and neglect; • applying knowledge of indicators to make judgements about risk of harm; • responding to indications of risk of harm, including complying with legislative and policy-based duties to report suspected child abuse and neglect.

From the Editor

In this issue of the Journal, the articles considered reflect the depth of research and practice that is unique to project management discipline. The range of topics addressed includes managing project contracts (Chan et al., “A Comparative Study of the Benefits of Applying Target Cost Contracts Between South Australia and Hong Kong”), managing project complexity (Chronéer and Bergquist, “Managerial Complexity in Process Industrial R&D Projects: A Swedish Study”), identifying early warning signs in complex projects (Williams et al., “Identifying and Acting on Early Warning Signs in Complex Projects”), project risk management (Krane, Olsson, and Rolstadås, “How Project Manager–Project Owner Interaction Can Work Within and Influence Project Risk Management”), exploring decisions regarding outsourcing and alignment of the project management office (Martins and Martins, “Outsourcing Operations in Project Management Offices: The Reality of Brazilian Companies”), and project management practices at strategic and tactical levels of the organization leading to sustainable development (Herazo, Lizarralde, and Paquin, “Sustainable Development in the Building Sector: A Canadian Case Study on the Alignment of Strategic and Tactical Management”).

Parking, parties and pets : disputes - the dark side of community living

In the last decade community living, in master planned communities or strata titled complexes, has increased. As land becomes scarcer, the popularity of these schemes is predicted to grow. Offsetting this popularity is the peculiarities of community living, in particular the often unthought-of difficulties arising from living in very close proximity to your neighbour. Such difficulties affect both amenity of life and property value. This paper seeks to inform practitioners of the issues arising from community living. It does this by identifying the more common forms of disputes and considering recent tribunal and court decisions. The paper concludes by identifying the dispute warning signs to assist to practitioners with the valuation process.

How childcare providers interpret "reasonable suspicion" of child abuse

- Background Childcare providers are often “first responders” for suspected child abuse, and how they understand the concept of “reasonable suspicion” will influence their decisions regarding which warning signs warrant reporting. - Objective The purpose of this study was to investigate how childcare providers interpret the threshold for reporting suspected abuse, and to consider the implications of these findings for professional training and development. - Method A convenience sample of 355 childcare providers completed the Reasonable Suspicion of Child Abuse survey to quantify what likelihood of child abuse constitutes “reasonable suspicion.” Responses were examined for internal consistency, evidence of a group standard, and associations with professional and personal demographics. - Results On a Rank Order Scale, responses for what constitutes “reasonable suspicion” ranged from requiring that abuse be “the” most likely cause (8 %) of an injury, to the second most likely (9 %), third (18 %), fourth (18 %), to even the seventh (8 %) or eighth (5 %) most likely cause of an injury. On a numerical probability scale, 21 % of respondents indicated that “abuse” would need to be ≥83 % likely before reasonable suspicion existed; 40 % stated that a likelihood between 53–82 % was needed; 27 % identified the necessary likelihood between 33–52 %; and 12 % set a threshold between 1–32 %. - Conclusions The present finding that no consensus exists for interpreting “reasonable suspicion” suggests that a broadly accepted interpretive framework is needed in order to help prepare childcare providers to know when to report suspected abuse.

Computational modeling and psychophysics in low- and mid-level vision

This thesis addresses a series of topics related to the question of how people find the foreground objects from complex scenes. With both computer vision modeling, as well as psychophysical analyses, we explore the computational principles for low- and mid-level vision.

We first explore the computational methods of generating saliency maps from images and image sequences. We propose an extremely fast algorithm called Image Signature that detects the locations in the image that attract human eye gazes. With a series of experimental validations based on human behavioral data collected from various psychophysical experiments, we conclude that the Image Signature and its spatial-temporal extension, the Phase Discrepancy, are among the most accurate algorithms for saliency detection under various conditions.

In the second part, we bridge the gap between fixation prediction and salient object segmentation with two efforts. First, we propose a new dataset that contains both fixation and object segmentation information. By simultaneously presenting the two types of human data in the same dataset, we are able to analyze their intrinsic connection, as well as understanding the drawbacks of today’s “standard” but inappropriately labeled salient object segmentation dataset. Second, we also propose an algorithm of salient object segmentation. Based on our novel discoveries on the connections of fixation data and salient object segmentation data, our model significantly outperforms all existing models on all 3 datasets with large margins.

In the third part of the thesis, we discuss topics around the human factors of boundary analysis. Closely related to salient object segmentation, boundary analysis focuses on delimiting the local contours of an object. We identify the potential pitfalls of algorithm evaluation for the problem of boundary detection. Our analysis indicates that today’s popular boundary detection datasets contain significant level of noise, which may severely influence the benchmarking results. To give further insights on the labeling process, we propose a model to characterize the principles of the human factors during the labeling process.

The analyses reported in this thesis offer new perspectives to a series of interrelating issues in low- and mid-level vision. It gives warning signs to some of today’s “standard” procedures, while proposing new directions to encourage future research.
