Reconstructing the Risk–Need–Responsivity model : a theoretical elaboration and evaluation

In this paper, we examine the theoretical strengths and weaknesses of the Risk–Need–Responsivity (RNR) model of offender rehabilitation. We briefly discuss the nature of rehabilitation theories and their core components and then review the three source theories associated with the RNR Model. Following this we set out to reconstruct the RNR model in light of this analysis, essentially arguing that there are at least three components to any rehabilitation theory: (a) primary aims, values and principles; (b) etiological and methodological assumptions; and (c) practice implications. We then evaluate the theoretical and empirical adequacy of the RNR model. Finally, we conclude the paper with a few comments on the policy, research, and clinical implications of our evaluation (and reconstruction) of this important rehabilitation model.

Analysis and modelling of critical infrastructure systems

The increasing complexity and interconnectedness of critical infrastructure systems, including the information systems and communication networks that support their existence and functionality, poses questions and challenges. Particularly, in terms of modelling and analysis of the security, survivability and ultimately reliability and continued availability of critical infrastructure systems and the services they deliver to modern society. The focus of this research enquiry is with regard to critiquing and modelling critical infrastructure systems. There are numerous systems analyse and modelling approaches that outline any number of differing methodological approaches, each with their own characteristics, expertise, strengths and weaknesses. The intention of this research is to investigate the merit of applying a ‘softer’ approach to critical infrastructure system security analysis and modelling that broadly views the systems in holistic terms, including their relationships with other systems. The intention is not to discuss or criticise existing research applying quantitative approaches, but to discuss a ‘softer’ system analysis and modelling approach in a security context that is adaptable to analysis modelling of critical infrastructure systems.

Public policy and USM : an approach to fit a renewed sense of public purpose

Malaysian Higher educational reform is an important and central aspect of the broader Malaysian public policy focus on excellence, development and national growth. This proposed paper intends to discuss analyze and critique the APEX program for Malaysian Universities. In particular the paper will investigate and discuss the way Universiti Sains Malaysia has interpreted and developed its strategic goals in light of its award of APEX status. Specifically I intend to discuss the strengths and limitations of the Universiti Sains Malaysia agenda, and contextualize it within a broader discussion about the directions of Malaysian Higher Education, in conditions of globalization, network society, and the knowledge economy. The challenges faced by the reform agenda at USM are significant and it is important that any understanding of the USM agenda be informed by deep reflection on the underlying philosophical aims and justifications for its direction. In this way my paper will attempt to show how the USM project is both an important part of Malaysian national development and a critical response to contemporary globalization, while at the same time an innovative and challenging intervention into public policy debate in Higher Education. The values and objectives of USM in regards to its strategic reorientation have implications far beyond the Higher Education sector and these implications will also be discussed.

A comparative assessment of the information technology services sector in India and China

The purpose of this paper is to assess the nature of competition in the information technology (IT) services sector between India and China. Using primary and secondary data sources, we compare and contrast the strengths and weaknesses of the IT services sector in the two countries along the main dimensions of Porter’s competitive advantage model. The principal findings indicate that the IT services sectors in the two countries are distinctively different, have developed along different paths and are highly complementary to each other. China has a well established hardware sector and its IT services sector focuses mostly on servicing its domestic market. India’s IT services sector is predominantly export orientated with focus on the US and Western European markets. Contrary to popular beliefs, given the complementary characteristics of the IT services sectors in India and China, it is unlikely for the two countries to compete against each other in the near future and greater strategic co-operation between IT service providers in the two countries is a more likely outcome.

Accountability structures and management relationships of internal audit : an Australian study

Purpose – The purpose of this study is to examine the accountability structures and the management relationships of internal audit. In particular, related issues such as the predominant internal audit objectives and the related functions, the extent to which internal audit addresses any financial reporting risks and the manner in which internal auditors in Australia perform their tasks, are identified. The study also looks at the extent of compliance with the Institute of Internal Auditors (IIA) Standards.
Design/methodology/approach – Based on a survey of the chief audit executives in Australia, the study identifies the reporting mechanisms, functions and relationships of internal audit, including the contributions made towards good corporate governance. There is, however, some misalignment between the aspirations of internal auditors and their relationships with management.
Findings – While internal audit objectives have been established with a focus on controls, risks and governance, the study has highlighted the fact that there is a lack of correlation between the tasks performed by internal auditors and the important internal audit objectives, with the exception of internal control and risks. The results also suggest that internal auditors have been providing an internal consulting and advisory role in matters concerning IT systems, strategic risks and financial issues. If internal auditors are to proactively contribute to good corporate governance, they need to define how, and in what way, this can be done. In regard to corporate governance processes, the results of the research indicate that issues surrounding internal control, risk assessment and management processes are regarded as the key factors for internal audit to contribute to good corporate governance.
Originality/value – This study complements and contributes to the existing literature in providing insights into the evolving role of the internal audit function in terms of accountabilities and relationships with management. It also provides a valuable insight into how the internal audit profession can build upon its inherent strengths and address any apparent areas of concern. This will assist both the profession and policy makers alike, in better understanding and improving the role of the internal audit process.

Contrasting the perceptions of child testimony experts, prosecutors and police officers regarding individual child abuse interviews

The aim of this study was to compare and contrast the perceptions of various stakeholders regarding a series of interviews about child abuse. Eight focus groups were conducted, each involving a police officer (child abuse investigator), a prosecutor who specializes in child abuse and a child testimony expert. The aim of the focus groups was to discuss the strengths and weaknesses of the specific interviews, which were conducted by the police officer in each focus group. Thematic analysis showed that the prosecutors and child testimony experts were relatively consistent in their perceptions about the need for more free narrative from child witnesses, and to ensure that police officers demonstrate open-mindedness when interviewing children. Differences in priorities and assumptions about the value of various interview techniques, however, were found among the stakeholders. These differences and their practical implications are discussed.

Stakeholder analysis in urban development : the application of stakeholder circle methodology and social network analysis

The increasing research interest on stakeholder analysis in urban planning reflects a growing recognition that stakeholders can and should influence the decision-making. This paper concentrates on exploring the techniques for analysing stakeholders, especially the application of the Stakeholder Circle tool and Social Network Analysis. An urban renewal project and an infrastructure project in Australia are presented as case studies to verify the use of these two techniques. The stakeholders are identified and prioritized from two different points of view, namely, the attribute evaluations in the Stakeholder Circle tool, and the relationship network analysis. The paper ends with a discussion on the strengths and limitations of the techniques for stakeholder analysis. No method for stakeholder identification and prioritization is perfect. The selection of the approaches is an art with extensive considerations of ‘when, what, and how’ to choose methods to achieve the project objectives. Each method has its own strengths and limitations. Combining several methods when necessary is the best way to analyse stakeholders.

Supermarket Healthy Eating for Life (SHELf): protocol of a randomised controlled trial promoting healthy food and beverage consumption through price reduction and skill-building strategies

Background: In the context of rising food prices, there is a need for evidence on the most effective approaches for promoting healthy eating. Individually-targeted behavioural interventions for increasing food-related skills show promise, but are unlikely to be effective in the absence of structural supports. Fiscal policies have been advocated as a means of promoting healthy eating and reducing obesity and nutrition-related disease, but there is little empirical evidence of their effectiveness. This paper describes the Supermarket Healthy Eating for LiFe (SHELf) study, a randomised controlled trial to investigate effectiveness and cost-effectiveness of a tailored skill-building intervention and a price reduction intervention, separately and in combination, against a control condition for promoting purchase and consumption of healthy foods and beverages in women from high and low socioeconomic groups.
Methods/design: SHELf comprises a randomised controlled trial design, with participants randomised to receive either (1) a skill-building intervention; (2) price reductions on fruits, vegetables and low-joule soft drink beverages and water; (3) a combination of skill-building and price reductions; or (4) a control condition. Five hundred women from high and low socioeconomic areas will be recruited through a store loyalty card program and local media. Randomisation will occur on receipt of informed consent and baseline questionnaire. An economic evaluation from a societal perspective using a cost-consequences approach will compare the costs and outcomes between intervention and control groups.
Discussion: This study will build on a pivotal partnership with a major national supermarket chain and the Heart Foundation to investigate the effectiveness of intervention strategies aimed at increasing women’s purchasing and consumption of fruits and vegetables and decreased purchasing and consumption of sugar-sweetened beverages. It will be among the first internationally to examine the effects of two promising approaches - skill-building and price reductions - on diet amongst women.

Indoor location prediction using multiple wireless received signal strengths

This paper presents a framework for indoor location prediction system using multiple wireless signals available freely in public or office spaces. We first propose an abstract architectural design for the system, outlining its key components and their functionalities. Different from existing works, such as robot indoor localization which requires as precise localization as possible, our work focuses on a higher grain: location prediction. Such a problem has a great implication in context-aware systems such as indoor navigation or smart self-managed mobile devices (e.g., battery management). Central to these systems is an effective method to perform location prediction under different constraints such as dealing with multiple wireless sources, effects of human body heats or mobility of the users. To this end, the second part of this pa- per presents a comparative and comprehensive study on different choices for modeling signals strengths and prediction methods under different condition settings. The results show that with simple, but effective modeling method, almost perfect prediction accuracy can be achieved in the static environment, and up to 85% in the presence of human movements. Finally, adopting the proposed framework we outline a fully developed system, named Marauder, that support user interface interaction and real-time voice-enabled location prediction.

The association between perceived sweetness intensity and dietary intake in young adults

Individual differences in taste perception may influence dietary habits, nutritional status, and ultimately nutrition-related chronic disease risk. Individual differences in sweetness intensity perception and the relationship between perceived sweetness intensity, food behaviors, and dietary intake was investigated in 85 adults. Subjects (body mass index [BMI]= 21 ± 3, 21 ± 4 y) completed a food and diet questionnaire, food variety survey, 2 24-h food records, and a perceived sweetness intensity measurement using the general labeled magnitude scale (gLMS). There was interindividual variation in perceived sweetness intensity (0 to 34 gLMS units, mean 10 ± 7). One-way analysis of variance (ANOVA) revealed no difference between perceived sweetness intensity and degree of importance placed on not adding sugar to tea or coffee (P = 0.2) and the degree of importance placed on avoiding sugar-sweetened or fizzy drinks (P = 1.0). Independent t-test analysis revealed no significant association between perceived sweetness intensity and the food variety measure for sugar and confectionary intake (P = 0.6) and selected fruit and vegetable intake (P = 0.1 to 0.9). One-way ANOVA also demonstrated no difference between tertiles of sweetness intensity and BMI (P = 0.1), age (P = 0.3), and food variety score (P = 0.5). No correlation was observed with regards to perceived sweetness intensity and mean total energy (kJ) intake (r = 0.05, P = 0.7), percent energy from total fat, saturated fat, protein, carbohydrate, and grams of fiber (r =–0.1 to 0.1, P = 0.2 to 0.8) and also for intake of the micronutrients: folate, magnesium, calcium, iron, and zinc (r = 0.1 to 0.2, P = 0.1 to 0.4). Only modest correlations were observed between sodium (r = 0.3, P < 0.05), vitamin C (r = 0.3, P < 0.05), and potassium (r = 0.2, P < 0.0) intake and perceived sweetness intensity. Overall, perceived sweetness intensity does not appear to play a role in food behaviors relating to sugar consumption and dietary intake in adults.

Mobile technology platforms for flexible access to information resources : considerations in the use of ebook readers, smart phones, netbooks and iPads

Smart phones are everywhere, people are taking eBook readers on holiday, the iPad has queues of people wanting to buy one, and some netbooks can fit in a pocket. The technology is attractive and increasingly affordable – how can it help an individual in their access to and use of texts, journals, databases, clinical sources, the web and day-to-day information? The Library has been investigating and trialling mobile devices during 2010, and has received interesting feedback from staff and students on the effectiveness of the technology in the University and personal environments. Each device has its strengths and weaknesses depending on the needs of the individual or activity it is supporting – productivity, research, study, clinical or recreational. The presentation will explore these issues along with some of the practical implications at Deakin, and international experiences in academic environments.

Cultural influences on body dissatisfaction, body change behaviours and disordered eating of Japanese adolescents

We administered a paper-and-pencil questionnaire to 133 female and 99 male Japanese high school students 13–18 years old (M = 15.9, SD = 1.57) from the Kansai area to examine cultural influences on their body image and body change behaviours. Our aim was to ascertain the independent and combined influences from traditional Japanese, modern Japanese, and Western values. Cluster analyses identified four ‘acculturative’ groups: ‘anti-modern’, ‘traditional’, ‘pro-modern/anti-traditional’, and ‘pro-Western/anti-Japanese’. Pro-modern and pro-Western adolescents were most dissatisfied with their bodies, and pro-Western adolescents were also most likely to attempt weight loss. The results demonstrate the value of assessing cultural interactions in Japan along three dimensions.

Effects of Si on microstructural evolution and mechanical properties of hot-rolled ferrite and bainite dual-phase steels

Based on the thermo-mechanical controlled process, the effects of Si on microstructural evolution, tensile properties, impact toughness, and stretch-flangeability of ferrite and bainite dual-phase (FBDP) steels were systematically investigated. The addition of Si from 0 to 0.95% promoted the formation of fine and equiaxed ferrite grains, and high Si (0.95%) also resulted in the formation of blocky martensite islands and retained austenite. Yield and tensile strengths, and uniform and total elongations all increased with increasing Si content. Therefore, the tensile strength and ductility balance was improved by Si addition due to the increasing strain-hardening rate. The fractured morphologies after hole-expansion showed that the excellent stretch-flangeability of FBDP steels was associated with the micro-cracks propagating through in ferrite phase as well as the elongated ferrite grains along the direction perpendicular to the crack. 0.95% Si steel had a similar high combination of tensile strength and impact toughness to 0.55% Si steel, and especially 0.95% Si steel exhibited an excellent combination of tensile strength and stretch-flangeability.

The quality of dietary intake methodology and reporting in child and adolescent obesity intervention trials : a systematic review

Assessing dietary intake is important in evaluating childhood obesity intervention effectiveness. The purpose of this review was to evaluate the dietary intake methods and reporting in intervention studies that included a dietary component to treat overweight or obese children. A systematic review of studies published in the English language, between 1985 and August 2010 in health databases. The search identified 2,295 papers, of which 335 were retrieved and 31 met the inclusion criteria. Twenty-three studies reported energy intake as an outcome measure, 20 reported macronutrient intakes and 10 studies reported food intake outcomes. The most common dietary method employed was the food diary (n = 13), followed by 24-h recall (n = 5), food frequency questionnaire (FFQ) (n = 4) and dietary questionnaire (n = 4). The quality of the dietary intake methods reporting was rated as ‘poor’ in 15 studies (52%) and only 3 were rated as ‘excellent’. The reporting quality of FFQs tended to be higher than food diaries/recalls. Deficiencies in the quality of dietary intake methods reporting in child obesity studies were identified. Use of a dietary intake methods reporting checklist is recommended. This will enable the quality of dietary intake results to be evaluated, and an increased ability to replicate study methodology by other researchers.

Using models in teaching and learning science

Models can be excellent tools to help explain abstract scientific concepts and for students to better understand these abstract concepts. A model could be a copy or replica, but it can also be a representation that is not like the real thing but can provide insight about a scientific concept. Models come in a variety of forms, such as three dimensional and concrete, two dimensional and pictorial, and digital forms. The features of models often depend on their purpose: for example, they can be visual, to show what something might look like, dynamic to show how something might work, and or interactive to show how something might respond to changes. One model is often not an accurate representation of a concept, so multiple models may be used.
Students’ modelling ability has been shown to improve through instruction and with practice of mapping the model to the real thing, highlighting the similarities and differences. The characteristics of a model that can be used in this assessment include accuracy and purpose. Models are commonly used by science teachers to describe, and explain scientific concepts, however, pedagogical approaches that include students using models to make predictions and test ideas about scientific concepts encourages students to use models for higher order thinking processes. This approach relates the use of models to the way scientists work, reflecting the nature of science and the development of scientific ideas. This chapter will focus on the way models are used in teaching: identifying pedagogical processes to raise students’ awareness of characteristics of models. In this way, the strengths and limitations of any model are assessed in relation to the real thing so that the accuracy and merit of the model and its explanatory power can be determined.
