Public and stakeholder values and knowledge of wildlife in Victoria, Australia

Prompted by a lack of human dimensions research in Australia, this study investigated the values and knowledge relating to wildlife held by members of the public within distinct demographic subsets of the Victorian population and members of wildlife management stakeholder groups; and compared these characteristics with how Victorian wildlife managers perceive these groups. A combination of semi-structured interviews and postal questionnaires were used. Fifteen in-depth interviews were conducted to explore how wildlife managers perceive the values and knowledge of wildlife held by members of various subsets of the Victorian population. A total of 1,431 questionnaires were completed by members of 13 public and stakeholder groups throughout Victoria, and these were analysed to explore values and knowledge relating to wildlife in Victoria. The findings of this study suggest that Victorian people have a strong emotional attachment to individual animals (the humanistic value), and an interest in learning about wildlife (the curiosity/learning/interacting value). The dominionistic/wildlife-consumption, utilitarian-habitat, aesthetic and negativistic values were not expressed by the majority of respondents from the public samples. The data also suggest that Victorian people have relatively low levels of factual knowledge about Australian wildlife. Thus, wildlife managers should expect support for wildlife management objectives that reflect the strong humanistic orientation of Victorians and tailor management and education programs to appeal to this value and Victorians' interest in learning about wildlife. Members of the Field Naturalists Club of Victoria (FNCV), Bird Observers Club of Australia (BOCA), Australian Conservation Foundation (ACF) stakeholder groups and management agency Parks Victoria expressed a strong interest in learning about wildlife. Members of the Royal Society for the Prevention of Cruelty to Animals (RSPCA) obtained high humanistic value scores; and members of the Victorian Field and Game Association (VFGA) obtained high domimomstic/wildlife-consumption value scores. Importantly, the humanistic and curiosity/learning/interacting values were the most strongly expressed values in all six groups and these values could be the key to more effective communication and collaboration between groups. Relationships between demographic factors, and values and knowledge relating to wildlife were found. For example, rural Victorians held a stronger dominionistic/ wildlife-consumption value than urban Victorians; females held stronger humanistic, curiosity/learning/interacting and negativistic values than males; young Victorians (18-34 years) held a lower curiosity/learning/interacting value and lower factual knowledge of wildlife than older Victorians; and more highly educated Victorians were more knowledgeable about wildlife than people with less formal education. No statistically significant differences were found between the values and knowledge of wildlife held by different income classes. While relationships between demographic factors, and values and knowledge relating to wildlife were found, they were generally much smaller than expected based on wildlife managers' perceptions and previous research. For example, the results suggest that Victorian females have a slightly stronger humanistic value of wildlife than males do. However, the important message emerging from the data is that males and females both express a strong emotional attachment to individual animals. Importantly, the results indicate that the effects of demographic factors on values and knowledge relating to wildlife are not always consistent across different geographic locations and stakeholder groups. For example, the slightly stronger interest in learning about wildlife among females when compared with males was observed in the rural and urban-fringe samples but not in the urban samples. This suggests that caution must be used when generalising the findings from human dimensions studies from one type of community or stakeholder group to another. Management programs should be tailored to the specific characteristics of the target audience. The findings also indicate that Victorian wildlife managers have diverse perceptions about the values and knowledge of wildlife held by members of different publics and stakeholder groups, and that the perceptions held by wildlife managers are not always consistent with the actual values and knowledge of wildlife held by members of different publics and stakeholders. For example, counter to the perceptions expressed by the interviewed wildlife managers, the interest in and factual knowledge of wildlife held by members of voluntary conservation groups equalled or surpassed that of wildlife managers; young Victorian adults (18-34 years) held a slightly lower curiosity/learning/interacting value and slightly lower level of factual knowledge of wildlife than older Victorians; and rural and urban communities in Victoria held low dominionistic and utilitarian values. Such discrepancies highlight the importance of investigating the actual values and knowledge held by members of such groups, so that appropriate and effective wildlife management programs can be implemented. Inaccurate perceptions and assumptions may contribute to ineffective communication between managers, stakeholders and publics; and adversely effect the success of wildlife management programs.

Agent-based hybrid framework for decision making on complex problems

Electronic commerce and the Internet have created demand for automated systems that can make complex decisions utilizing information from multiple sources. Because the information is uncertain, dynamic, distributed, and heterogeneous in nature, these systems require a great diversity of intelligent techniques including expert systems, fuzzy logic, neural networks, and genetic algorithms. However, in complex decision making, many different components or sub-tasks are involved, each of which requires different types of processing. Thus multiple such techniques are required resulting in systems called hybrid intelligent systems. That is, hybrid solutions are crucial for complex problem solving and decision making. There is a growing demand for these systems in many areas including financial investment planning, engineering design, medical diagnosis, and cognitive simulation. However, the design and development of these systems is difficult because they have a large number of parts or components that have many interactions. From a multi-agent perspective, agents in multi-agent systems (MAS) are autonomous and can engage in flexible, high-level interactions. MASs are good at complex, dynamic interactions. Thus a multi-agent perspective is suitable for modeling, design, and construction of hybrid intelligent systems. The aim of this thesis is to develop an agent-based framework for constructing hybrid intelligent systems which are mainly used for complex problem solving and decision making. Existing software development techniques (typically, object-oriented) are inadequate for modeling agent-based hybrid intelligent systems. There is a fundamental mismatch between the concepts used by object-oriented developers and the agent-oriented view. Although there are some agent-oriented methodologies such as the Gaia methodology, there is still no specifically tailored methodology available for analyzing and designing agent-based hybrid intelligent systems. To this end, a methodology is proposed, which is specifically tailored to the analysis and design of agent-based hybrid intelligent systems. The methodology consists of six models - role model, interaction model, agent model, skill model, knowledge model, and organizational model. This methodology differs from other agent-oriented methodologies in its skill and knowledge models. As good decisions and problem solutions are mainly based on adequate information, rich knowledge, and appropriate skills to use knowledge and information, these two models are of paramount importance in modeling complex problem solving and decision making. Follow the methodology, an agent-based framework for hybrid intelligent system construction used in complex problem solving and decision making was developed. The framework has several crucial characteristics that differentiate this research from others. Four important issues relating to the framework are also investigated. These cover the building of an ontology for financial investment, matchmaking in middle agents, reasoning in problem solving and decision making, and decision aggregation in MASs. The thesis demonstrates how to build a domain-specific ontology and how to access it in a MAS by building a financial ontology. It is argued that the practical performance of service provider agents has a significant impact on the matchmaking outcomes of middle agents. It is proposed to consider service provider agents' track records in matchmaking. A way to provide initial values for the track records of service provider agents is also suggested. The concept of ‘reasoning with multimedia information’ is introduced, and reasoning with still image information using symbolic projection theory is proposed. How to choose suitable aggregation operations is demonstrated through financial investment application and three approaches are proposed - the stationary agent approach, the token-passing approach, and the mobile agent approach to implementing decision aggregation in MASs. Based on the framework, a prototype was built and applied to financial investment planning. This prototype consists of one serving agent, one interface agent, one decision aggregation agent, one planning agent, four decision making agents, and five service provider agents. Experiments were conducted on the prototype. The experimental results show the framework is flexible, robust, and fully workable. All agents derived from the methodology exhibit their behaviors correctly as specified.

Fall incidence and fall prevention practices at acute care hospitals in Singapore : a retrospective audit

Objective To investigate the incidence of falls and explore fall prevention practices at acute care hospitals in Singapore.

Design A retrospective audit to collect baseline data on (1) incidence of falls (patient fall rates and fall injury rates) and (2) fall prevention practices, was conducted in five acute care hospitals in Singapore from December 2004 to March 2005.

Study participants Medical record data (n = 6000) of patients admitted into the medical, surgical and geriatric units in the five hospitals.

Outcome measures Fall incidence was obtained from the hospital's fall databases and incident reports for the period of June 2003 to May 2004. In total, 6000 medical records from five hospitals were randomly selected, retrieved and reviewed to determine whether falls, fall assessments and interventions were being initiated and documented.

Results The number of fallers for all hospitals was 825. Analysis showed that patient fall rates ranged from 0.68 to 1.44 per 1000 patient days, and the proportion of falls associated with injury ranged from 27.4% to 71.7%. The use of a fall risk assessment tool by nurses was recorded in 77% of all the nursing records.

Conclusion This study has laid the foundation for further research for fall prevention in Singapore by describing current fall rates, fall-associated injury rates and the status of fall prevention practices in acute care settings. The results will be used to inform the development of a tailored multifaceted strategy to facilitate the implementation of Fall Prevention Clinical Practice Guidelines to reduce the burden of falls and fall injuries in hospitals in Singapore.

Apatite formation on nano-structured titanium and niobium surface

Current orthopaedic biomaterials research mainly focuses on developing implants that could induce controlled, guided and rapid healing. In the present study, the surface morphologies of titanium (Ti) and niobium (Nb) metals were tailored to form nanoporous, nanoplate and nanofibrelike structures through adjustment of the temperature in the alkali treatment. The in vitro bioactivity of these structures was then evaluated by soaking in simulated body fluid (SBF). It was found that the morphology of the modified surface significantly influenced the apatite inducing ability. The Ti surface with a nanofiber-like structure showed better apatite inducing ability, than the nanoporous or nanoplate surface structures. A thick dense apatite layer formed on the Ti surface with nanofiberlike structure after 1 week soaking in SBF. It is expected that the anofibre-like surface could achieve good apatite formation in vivo and subsequently enhance osteoblast cell adhesion and bone formation in vivo.

Superhydrophobic modification of polyimide films based on gold-coated porous silver nanostructures and self-assembled monolayers

We present a facile and effective method for controlling the surface hydrophobicity of polyimide films from sticky to superhydrophobic properties by tailoring their topographies. Nanostructured silver layers were produced on polyimide films by treatment with aqueous KOH and AgNO3, followed by thermal treatment at 200 degrees C or higher temperatures. Further modification of the gold-coated silver layers with n-dodecanethiol led to hydrophobic surfaces. Different morphologies of the silver layers at the micro- and nano-meter scales, which result in the variety of hydrophobicity, can be tailored by controlling the thermal treatment temperature. Surfaces prepared at 320 degrees C showed a sticky property that water drops did not slide off even when the sample was held upside down. Superhydrophobic surfaces were obtained when the temperature was above 340 degrees C. A remarkable superhydrophobicity, as evidenced by a very large water contact angle of 162 degrees and a very small sliding angle of 7 degrees, was achieved by heating the modified polyimide films at 360 degrees C. This is also the first example for superhydrophobic modification of polyimide films.

Advanced virtual engineering educational program for engineering research and teaching excellence

In this paper, an advanced virtual engineering educational program developed at University of South Australia for both on-campus and off-shore students will be studied. This extensive training program is based on a comprehensive online tutorial and comprises both face-to-face and online learning. The program provides a tailored evaluation format to ensure that all postgraduate students, including course work and research students, will have appropriate exposure to updated learning skills and research resources. Although the internet (WWW) is the primary resource being used in this educational program, other resources such as video conference, video taping, and face-to-face lecturing have also played a role in promoting engineering teaching and research excellence. The feedback from students in recent years has been very encouraging, showing increased information literacy skills and improved researching abilities. As off campus class numbers have increased, further development of the program to meet their requirement has been a priority.

Pi-shaped MEMS architecture for lowering actuation voltage of RF switching

A wide band low actuation capacitive coupling electrostatic RF MEMS switching device is presented in this paper. The device includes a pi-shaped matching architecture containing two switches connected by a high impedance short transmission line. The device can act as a switch for any desired frequency whilst requiring only 12volts for actuation. By optimizing the length and the characteristic impedance of the transmission line, the switch can be tailored for desired frequency bands. The switch is calculated and simulated for Ka to V frequency bands demonstrating excellent improvements of RF characteristics.

MUSTe method for quantifying virtual environment training system efficacy

In the current era increased attention and interest of utilizing advanced computer technologies for training and education at all managerial levels and functional areas is apparent. One of such technologies, virtual environment (VE), is perceived to be effective in enhancing human abilities to learn abstract concept and complex procedural tasks. Despite its adaptation for training and fast-paced technological advancements, ways in which to evaluate efficacy of such technology are unclear. We have approached this problem by developed a new evaluation method focus on cognitive, affective and skillbased learning dimensions, based on traditional usability evaluation methods but tailored to specifically suit for the quantification of 3D VE system. We first describe the construct of the new method and then report a study utilizing the method in the context of quantifying a VE efficacy in an object assembly task. At last, we discuss the implications of such a method.

A nurse-assisted screening and referral program for depression among survivors of colorectal cancer : feasibility study

Objective: To test the feasibility and acceptability of a telephone-based program to screen survivors of colorectal cancer (CRC) for distress, and to refer distressed patients to their treating health service.

Design, setting and participants: A prospective, multicentre study involving 59 patients with CRC recruited from six public and private health services in Melbourne, Victoria, from 15 June 2008 to 22 September 2009. Patients who had completed adjuvant chemotherapy for CRC were contacted (7–10 days after recruitment [outcall one] and again 4 weeks later [outcall two]) by the Cancer Council Victoria’s helpline nurse, and screened for distress with the Distress and Impact Thermometer (DIT); participants were given tailored information and support and those with distress scores of ≥5, and impact scores of ≥4, were referred for follow-up. Telephone interviews were conducted 4 weeks after outcall two. Participating helpline and health service staff were surveyed on the feasibility and acceptability of the service. Main outcome measure: Anxiety and depression, measured by the Hospital Anxiety and Depression Scale (HADS).

Results: Of the 59 patients (87%) who agreed to participate, 63% were men; their mean age was 59 years (SD, 9.5 years). HADS depression decreased significantly from baseline (mean score, 4.93; SD, 4.22) to follow-up (mean score, 3.84; SD, 4.10; Z = −2.375; P= 0.02). However, there was no significant difference in HADS anxiety between baseline (mean score, 5.29; SD, 4.11) and follow-up (mean score, 4.78; SD, 3.65). Outcall one generated two referrals (4% of participants) and outcall two generated four referrals
(8%); five of these six participants took up the referrals. Satisfaction with the program among participants was high; 82% found outcall one “quite or very helpful” and 79% found outcall two “quite or very helpful”. Helpline and health service staff reported a straightforward process that did not adversely affect workloads.

Conclusion: This model of care carries the potential to meet ongoing psychosocial needs of survivors of CRC.

Developing a graduate diploma to cater for career-change adults

A seven-month intensive graduate diploma of teaching course was developed in 2007 to cater for an increasing demand for qualified teachers. The course is developed to university standards and is accredited by teacher registration authorities, with graduates obtaining a qualification as a teacher at the end of the seven month period. The course is tailored to recognise and build on the existing academic attributes and capacifies expected of top tertiary graduates, and to be appropriate to academically-experienced adult learning styles. This paper will discuss the process involved in the course development. Aspects related to the student cohort demographics and leaming styles will be highlighted. A 'nested case study approach' involving both qualitative and quantitative data collection was used. Questionnaires, surveys, and interviews were used to gather the data from stakeholders (post-graduate students) involved in this aspect of the research. The analysis of the data will provide detail on the aspects of the course which enabled mature-aged students to succeed and highlight future challenges.

The association between physical activity and depression among young women

Young women experiencing depressive symptoms were shown to have different constraints to being active compared to young women without depressive symptoms, such as lower motivation and lower confidence in their ability to be active. Physical activity promotion initiatives may benefit from individually-tailored, multi-component programs rather than a 'one-fits-all', single-arm approach

Teaching journalism students and regional reporters how to work with cultural diversity

This paper examines the effectiveness of a set of curriculum materials developed for a Reporting Diversity and Integration Project tailored for Australian journalists and journalism students. The materials take a problem-based learning (PBL) approach to a hypothetical case study that involves Muslim netballers being banned from competition because they want to wear headscarves during play. Deferring to ideas developed by Russian psychologist, Leo Vygotsky, we proposed a few ‘scaffolding’ strategies to support student learning. The material was trialed with 30 first-year Deakin University journalism students and 30 regional journalists. The responses showed that both groups felt the materials we added to the curriculum resources, which provided information on Muslim women and the headscarf, affected how they would write the story. They also thought it was important to provide this kind of information for readers. This paper argues that providing cultural information in an accessible format for students and journalists in newsrooms should be integral to education and training materials designed to improve media coverage of cultural diversity issues.

An exploratory cluster randomised controlled trial of knowledge translation strategies to support evidence-informed decision-making in local governments (The KT4LG study)

Background: Childhood overweight and obesity is the most prevalent and, arguably, politically complex child health problem internationally. Governments, communities and industry have important roles to play, and are increasingly expected to deliver an evidence-informed system-wide prevention program. However, efforts are impeded by a lack of organisational access to and use of research evidence. This study aims to identify feasible, acceptable and ideally, effective knowledge translation (KT) strategies to increase evidence-informed decision making in local governments, within the context of childhood obesity prevention as a national policy priority.
Methods/Design: This paper describes the methods for KT4LG, a cluster randomised controlled trial which is exploratory in nature, given the limited evidence base and methodological advances. KT4LG aims to examine a program of KT strategies to increase the use of research evidence in informing public health decisions in local governments. KT4LG will also assess the feasibility and acceptability of the intervention. The intervention program comprises a facilitated program of evidence awareness, access to tailored research evidence, critical appraisal skills development, networking and evidence summaries and will be compared to provision of evidence summaries alone in the control program. 28 local governments were randomised to intervention or control, using computer generated numbers, stratified by budget tertile (high, medium or low). Questionnaires will be used to measure impact, costs, and outcomes, and key informant interviews will be used to examine processes, feasibility, and experiences. Policy tracer studies will be included to examine impact of intervention on policies within relevant government policy documents.
Discussion: Knowledge translation intervention studies with a focus on public health and prevention are very few in number. Thus, this study will provide essential data on the experience of program implementation and evaluation of a system-integrated intervention program employed within the local government public health context. Standardised programs of system, organisational and individual KT strategies have not been described or rigorously evaluated. As such, the findings will make a significant contribution to understanding whether a facilitated program of KT strategies hold promise for facilitating evidence-informed public health decision making within complex multisectoral government organisations.
