Suspected child abuse and neglect reporting behaviour

Executuve Summary Background and Aims Child abuse and neglect is a tragedy within our community, with over 10,000 substantiated reports of abuse and neglect in Queensland in the past year. The considerable consequences of child abuse and neglect are far-reaching, substantial and can be fatal. The reporting of suspicions of child abuse or neglect is often the first step in preventing further abuse or neglect. In the State of Queensland, medical practitioners are mandated by law to report their suspicions of child abuse and neglect. However, despite this mandate many still do not report their suspicions. A 1998 study indicated that 43% of medical practitioners had, at some time, made a conscious decision to not report suspected abuse or neglect (Van Haeringen, Dadds & Armstrong, 1998). The aim of this study was to gain a better understanding of beliefs about reporting suspected child abuse and neglect and the barriers to reporting suspected abuse and neglect by medical practitioners and parents and students. The findings have the potential to inform the training and education of members of the community who have a shared responsibility to protect the wellbeing of its most vulnerable members. Method In one of the largest studies of reporting behaviour in relation to suspected child abuse and neglect in Australia, we examined and compared medical practitioners’ responses with members of the community, namely parents and students. We surveyed 91 medical practitioners and 214 members of the community (102 parents and 112 students) regarding their beliefs and reporting behaviour related to suspected child abuse and neglect. We also examined reasons for not reporting suspected abuse or neglect, as well as awareness of responsibilities and the appropriate reporting procedures. To obtain such information, participants anonymously completed a comprehensive questionnaire using items from previous studies of reporting attitudes and behaviour. Executive Summary Abused Child Trust Report August 2003 5 Findings Key findings include: • The majority of medical practitioners (97%) were aware of their duty to report suspected abuse and neglect and believed they had a professional and ethical duty to do so. • A majority of parents (82%) and students (68%) also believed that they had a professional and ethical duty to report suspected abuse and neglect. • In accord with their statutory duty to report suspected abuse and neglect, 69% of medical practitioners had made a report at some point. • Sixteen percent of parents and 9% of students surveyed indicated that they had reported their suspicions of neglect and abuse. • The most endorsed belief associated with not reporting suspected child abuse and neglect was that, ‘unpleasant events would follow reporting’. • Over a quarter of medical practitioners (26%) admitted to making a decision not to report their suspicions of child abuse or neglect on at least one occasion. • Compared with previous research, there has been a decline in the number of medical practitioners who decided not to report suspected abuse or neglect from 43% (Van Haeringen et al., 1998) to 26% in the current study. • Fourteen percent of parents and 15% of students surveyed had also chosen not to report a case of suspected abuse or neglect. • Attitudes that most strongly influenced the decision to report or not report suspected abuse or neglect differed between groups (medical practitioners, parents, or students). A belief that, ‘the abuse was a single incident’ was the best predictor of non-reporting by medical practitioners, while having ‘no time to follow-up the report’ or failing to be ‘convinced of evidence of abuse’ best predicted failure to report abuse by students. A range of beliefs predicted non-reporting by parents, including the beliefs that reporting suspected abuse was ‘not their responsibility’ and ‘knowing the child had retracted their statement’. Conclusions Of major concern is that approximately 25% of medical practitioners with a mandated responsibility to report, as well as some members of the general public, revealed that they have suspected child neglect or abuse but have made the decision not to report their suspicions. Parents and students perceived the general community as having responsibility for reporting suspicions of abuse or neglect. Despite this perception, they felt that lodging a report may be overly demanding in terms of time and they had the confidence in their ability to identify child abuse and neglect. An explanation for medical practitioners deciding not to report may be based upon their optimistic belief that suspected abuse or neglect was a single incident. Our findings may best be understood from the ‘inflation of optimism’ hypothesis put forward by the Nobel Laureate, Daniel Kahneman. He suggests that in spite of rational evidence, human beings tend to make judgements based on an optimistic view rather than engaging in a rational decision-making process. In this case, despite past behaviour of abuse or neglect being the best predictor of future behaviour, medical practitioners have taken an optimistic view, choosing to believe that their suspicion of child abuse or neglect represents a single incident. The clear implication of findings in the current research is the need for the members of the general community and medical practitioners to be better appraised of the consequences of their decision-making in relation to suspicionsof child abuse and neglect. Finally findings from parents and students relating to their reporting behaviour suggest that members of the larger community represent an untapped resourcewho might, with appropriate awareness, play a more significant role in theidentification and reporting of suspected child abuse and neglect.

Slotted distributed space-time coding

Distributed space-time coding (DSTC) exploits the concept of cooperative diversity and space-time coding to offer a powerful bandwidth efficient solution with improved diversity. In this paper, we evaluate the performance of DSTC with slotted amplify-and-forward protocol (SAF). Relay nodes between the source and the destination nodes are grouped into two relay clusters based on their respective locations and these relay clusters cooperate to transmit the space-time coded signal to the destination node in different time frames. We further extend the proposed Slotted-DSTC to Slotted DSTC with redundant code (Slotted-DSTC-R) protocol where the relay nodes in both relay clusters forward the same space-time coded signal to the destination node to achieve a higher diversity order.

Critical timescales and time intervals for coupled linear processes

In 1991, McNabb introduced the concept of mean action time (MAT) as a finite measure of the time required for a diffusive process to effectively reach steady state. Although this concept was initially adopted by others within the Australian and New Zealand applied mathematics community, it appears to have had little use outside this region until very recently, when in 2010 Berezhkovskii and coworkers rediscovered the concept of MAT in their study of morphogen gradient formation. All previous work in this area has been limited to studying single–species differential equations, such as the linear advection–diffusion–reaction equation. Here we generalise the concept of MAT by showing how the theory can be applied to coupled linear processes. We begin by studying coupled ordinary differential equations and extend our approach to coupled partial differential equations. Our new results have broad applications including the analysis of models describing coupled chemical decay and cell differentiation processes, amongst others.

Parents’ experience of time distortion following diagnosis of a serious or lethal fetal anomaly

PURPOSE: To explore the experience of couples who continued pregnancy following a diagnosis of serious or lethal fetal anomaly. STUDY DESIGN: Thirty-one male and female participants were recruited from a high-risk maternal–fetal medicine clinic in Washington State. Data were collected using in-depth interviews during pregnancy and after the birth of their baby. Transcribed interviews were thematically analyzed through the phenomenological lens of Merleau-Ponty. FINDINGS: Participants described how time became reconfigured and reconstituted as they tried to compress a lifetime of love for their future child into a limited period. Participants’ concepts of time became distorted and were related to their perceptual lived experience rather than the schedule-filled,regimented, linear clock time that governed the health professionals. CONCLUSION: Living in distorted time may be a mechanism parents use to cope with overwhelming and disorienting feelings when their unborn baby is diagnosed with a fetal anomaly.

Active versus passive screen time for young children

In this paper, we report some initial findings from our investigations into the Australian Government’s Longitudinal Study of Australian Children dataset. It is revealed that the majority of Australian children are exceeding the government’s Screen Time recommendations and that most of their screen time is spent as TV viewing, as opposed to video game play or computer use. In light of this finding,we review the body of research surrounding children’s engagement in Screen Time activities and the associated positive and negative effects. Based on existing evidence,we define two categories of Screen Time—Active Screen Time and Passive Screen Time. It is proposed that this distinction provides a more accurate classification of Screen Time and a more informative lens through which to consider the associated benefits and detrimental effects for young children.

Building intercultural competence one “Patch” at a time

This paper describes a program called Patches that was implemented to assist a group of Australian and Malaysian pre-service teachers to enhance their intercultural competence through their involvement in a series of reciprocal learning activities. Each learning experience was considered a “patch” that eventually created a “quilt of intercultural learning.” The purpose of this study was to enhance the intercultural competence of domestic and international students through organized intercultural activities, through a series of reflective writing sessions, and mutual engagement on a common project. The effectiveness of the Patches program was analysed in accordance with Deardorff’s elements of intercultural competence. The qualitative findings indicate that both cohorts of preservice teachers showed elements of intercultural competence through participation in the program, with both groups reporting a deeper appreciation and understanding of how to communicate more effectively in intercultural contexts.

Retirement villages : time for a change?

In retirement, many Australians relocate to a less onerous form of home occupation. Some downsize their house, or move to a strata title complex. Others, attracted by lifestyle perceptions, move into a retirement village. However, research shows Retirement Village documentation is complex and more analogous to commercial leasing than home ownership. The most recent government review by New South Wales, confirms the need for change. This paper identifies the current retirement village tenure models generally available in Australia. By comparing the various State/Territory systems the authors draw conclusions regarding the adoption of standardised documentation and uniform Australian Retirement Village legislation.

The high price of hesitation where time of the essence

The decision of Lai v Soineva [2011] QSC 247 in relation to the operation of standard conditions in the Queensland REIQ contract highlights a very practical issue often overlooked in the heat of a transaction .The point is relatively simple. In this instance ,the case concerned the interpretation of the printed "Building and Pest Inspection Clause" but is of relevance to the printed "Finance Clause" in the same contract as the wording and principles are identical. It highlights the issue of knowing well what is in the standard contract and not making assumptions. The case also highlights the cost to a party of dithering in making an election in a time of the essence environment

Microscopic cooperative traffic based on NGSIM data

The deployment of new emerging technologies, such as cooperative systems, allows the traffic community to foresee relevant improvements in terms of traffic safety and efficiency. Vehicles are able to communicate on the local traffic state in real time, which could result in an automatic and therefore better reaction to the mechanism of traffic jam formation. An upstream single hop radio broadcast network can improve the perception of each cooperative driver within radio range and hence the traffic stability. The impact of a cooperative law on traffic congestion appearance is investigated, analytically and through simulation. Ngsim field data is used to calibrate the Optimal Velocity with Relative Velocity (OVRV) car following model and the MOBIL lane-changing model is implemented. Assuming that congestion can be triggered either by a perturbation in the instability domain or by a critical lane changing behavior, the calibrated car following behavior is used to assess the impact of a microscopic cooperative law on abnormal lane changing behavior. The cooperative law helps reduce and delay traffic congestion as it increases traffic flow stability.

The effect of injury diagnosis on expected Postconcussion Syndrome (PCS) symptom reporting and illness perception

Objective: To determine if systematic variation of diagnostic terminology (i.e. concussion, minor head injury [MHI], mild traumatic brain injury [mTBI]) following a standardized injury description produced different expected symptoms and illness perceptions. We hypothesized that worse outcomes would be expected of mTBI, compared to other diagnoses, and that MHI would be perceived as worse than concussion. Method:108 volunteers were randomly allocated to conditions in which they read a vignette describing a motor vehicle accident-related mTBI followed by: a diagnosis of mTBI (n=27), MHI (n=24), concussion (n=31); or, no diagnosis (n=26). All groups rated: a) event ‘undesirability’; b) illness perception, and; c) expected Postconcussion Syndrome (PCS) and Posttraumatic Stress Disorder (PTSD) symptoms six months post injury. Results: On average, more PCS symptomatology was expected following mTBI compared to other diagnoses, but this difference was not statistically significant. There was a statistically significant group effect on undesirability (mTBI>concussion & MHI), PTSD symptomatology (mTBI & no diagnosis>concussion), and negative illness perception (mTBI & no diagnosis>concussion). Conclusion: In general, diagnostic terminology did not affect anticipated PCS symptoms six months post injury, but other outcomes were affected. Given that these diagnostic terms are used interchangeably, this study suggests that changing terminology can influence known contributors to poor mTBI outcome.

Learning hierarchical prototypes of motion time series for interactive systems

Abstract. For interactive systems, recognition, reproduction, and generalization of observed motion data are crucial for successful interaction. In this paper, we present a novel method for analysis of motion data that we refer to as K-OMM-trees. K-OMM-trees combine Ordered Means Models (OMMs) a model-based machine learning approach for time series with an hierarchical analysis technique for very large data sets, the K-tree algorithm. The proposed K-OMM-trees enable unsupervised prototype extraction of motion time series data with hierarchical data representation. After introducing the algorithmic details, we apply the proposed method to a gesture data set that includes substantial inter-class variations. Results from our studies show that K-OMM-trees are able to substantially increase the recognition performance and to learn an inherent data hierarchy with meaningful gesture abstractions.

Residence time investigation in a co-axial dielectric barrier discharge reactor

The residence time distribution (RTD) is a crucial parameter when treating engine exhaust emissions with a Dielectric Barrier Discharge (DBD) reactor. In this paper, the residence time of such a reactor is investigated using a finite element based software: COMSOL Multiphysics 4.3. Non-thermal plasma (NTP) discharge is being introduced as a promising method for pollutant emission reduction. DBD is one of the most advantageous of NTP technologies. In a two cylinder co-axial DBD reactor, tubes are placed between two electrodes and flow passes through the annuals between these barrier tubes. If the mean residence time increases in a DBD reactor, there will be a corresponding increase in reaction time and consequently, the pollutant removal efficiency can increase. However, pollutant formation can occur during increased mean residence time and so the proportion of fluid that may remain for periods significantly longer than the mean residence time is of great importance. In this study, first, the residence time distribution is calculated based on the standard reactor used by the authors for ultrafine particle (10-500 nm) removal. Then, different geometrics and various inlet velocities are considered. Finally, for selected cases, some roughness elements added inside the reactor and the residence time is calculated. These results will form the basis for a COMSOL plasma and CFD module investigation.

Rule-based transit signal priority control method using a real-time transit travel time prediction model

An advanced rule-based Transit Signal Priority (TSP) control method is presented in this paper. An on-line transit travel time prediction model is the key component of the proposed method, which enables the selection of the most appropriate TSP plans for the prevailing traffic and transit condition. The new method also adopts a priority plan re-development feature that enables modifying or even switching the already implemented priority plan to accommodate changes in the traffic conditions. The proposed method utilizes conventional green extension and red truncation strategies and also two new strategies including green truncation and queue clearance. The new method is evaluated against a typical active TSP strategy and also the base case scenario assuming no TSP control in microsimulation. The evaluation results indicate that the proposed method can produce significant benefits in reducing the bus delay time and improving the service regularity with negligible adverse impacts on the non-transit street traffic.

Efficient real-time face detection for high resolution surveillance applications

This paper presents an efficient face detection method suitable for real-time surveillance applications. Improved efficiency is achieved by constraining the search window of an AdaBoost face detector to pre-selected regions. Firstly, the proposed method takes a sparse grid of sample pixels from the image to reduce whole image scan time. A fusion of foreground segmentation and skin colour segmentation is then used to select candidate face regions. Finally, a classifier-based face detector is applied only to selected regions to verify the presence of a face (the Viola-Jones detector is used in this paper). The proposed system is evaluated using 640 x 480 pixels test images and compared with other relevant methods. Experimental results show that the proposed method reduces the detection time to 42 ms, where the Viola-Jones detector alone requires 565 ms (on a desktop processor). This improvement makes the face detector suitable for real-time applications. Furthermore, the proposed method requires 50% of the computation time of the best competing method, while reducing the false positive rate by 3.2% and maintaining the same hit rate.

The prevalence and perception of pain amongst hospital in-patients

The aim of this paper is to describe the prevalence and perceptions of pain and pain management amongst hospital in-patients. A cross-sectional descriptive survey of 205 patients was conducted. Presence and severity of pain was assessed using verbal descriptor and visual analogue scales, and perceptions of pain were assessed using multi-item scales. Although the severity of pain reported was consistent across age groups and clinical areas, women in the study sample were significantly more likely to report high levels of pain than men. Differences in how men and women communicate their pain were observed, with women indicating that they were less willing to ask for help with their pain. Results suggest that pain continues to be an important problem for a large number of men and women in hospital, and that the experience of pain impacts negatively upon their well-being. Gender differences in the experience of and response to pain remain important considerations for clinical nurses who have major responsibilities for the management of pain in hospitalized patients.
