Twitter free Iran: an evaluation of Twitter's role in public diplomacy and information operations in Iran's 2009 election crisis

Social media platforms such as Twitter pose new challenges for decision-makers in an international crisis. We examine Twitter’s role during Iran’s 2009 election crisis using a comparative analysis of Twitter investors, US State Department diplomats, citizen activists and Iranian protestors and paramilitary forces. We code for key events during the election’s aftermath from 12 June to 5 August 2009, and evaluate Twitter. Foreign policy, international political economy and historical sociology frameworks provide a deeper context of how Twitter was used by different users for defensive information operations and public diplomacy. Those who believe Twitter and other social network technologies will enable ordinary people to seize power from repressive regimes should consider the fate of Iran’s protestors, some of whom paid for their enthusiastic adoption of Twitter with their lives.

Evaluation of housing developments for sustainability using a multi-criteria approach

New housing developments in Australia, particularly on Greenfield sites on the edge of existing urban centres, need to be sustainable in environmental and social terms if long term problems are to be avoided. Sustainability is multi-dimensional and existing analyses have been found to be inadequate in assessing housing developments holistically. This paper describes research which has used five criteria (energy use, resource use, neighbourhood character, neighbourhood connectivity and diversity), representing 31 indicators, to assess three housing precincts of a regional city in southern Australia. The method has been found to produce useful assessments of sustainability. The method has the potential to inform future housing developments and to be used to improve existing suburbs.

Cross-cultural learning and international collaboration: evaluation of a study tour to Thailand

Purpose:
To evaluate cross-cultural learning among Thai staff and host students from the Faculty of Nursing, Mahidol University (MU) and Australian guest students from the School of Nursing and Midwifery, Deakin University (DU), who participated in a study tour.

Design:
Descriptive exploratory evaluation.

Methods:
Key stakeholders were invited to participate resulting in a convenience sample of seven MU staff, five MU and 22 DU students. Data were collected using mixed methods. Qualitative data were theme analysed and quantitative data were analysed using descriptive statistics.

Main findings:
The semi-structured interviews with MU staff, focus group with MU students and free response questions in the online survey with DU students indicated the themes of enhanced and valuable cross-cultural learning and relationship building, the challenges of different social behaviours and the importance of tolerance and acceptance. In the online survey, over 77% (n = 17) of DU students reported high satisfaction with their cross-cultural learning on the study tour. The online survey included the validated Miville-Guzman Universality-Diversity scale short form (M-GUD-S). All Australian students reported seeking diversity of contact (X ± SD = 23.1 ± 4.4), relativistic appreciation (X ± SD = 24.7 ± 3.9), and comfort with differences (X ± SD = 26.2 ± 3.0), indicating high levels of openness to cultural diversity and similarity on the M-GUD-S. 

Conclusion and recommendations:
This study provides an example of an evaluated study tour emphasising cross-cultural relationship building. Findings indicate that nursing education should include opportunities for intercultural exchange among nursing students. Nurses require excellent skills in cross-cultural nursing and relating to meet the future global challenges to health care over the next millennium.

Social and emotional wellbeing in Indigenous Australians: identifying promising interventions

Objective: 

Development and evaluation of a teaching and learning approach in cross-cultural care and antidiscrimination in university nursing students

Background:
Cross-cultural care and antidiscrimination are vital to ethical effective health systems. Nurses require quality educational preparation in cross-cultural care and antidiscrimination. Limited evidence-based research is available to guide teachers.

Objectives:
To develop, implement and evaluate an evidence-based teaching and learning approach in cross-cultural care and antidiscrimination for undergraduate nursing students.

Design:
A quantitative design using pre- and post-survey measures was used to evaluate the teaching and learning approach.

Settings:
The Bachelor of Nursing program in an Australian university.

Participants:
Academics and second year undergraduate nursing students.

Methods:
A literature review and consultation with academics informed the development of the teaching and learning approach. Thirty-three students completed a survey at pre-measures and following participation in the teaching and learning approach at post-measures about their confidence to practice cross-cultural nursing (Transcultural Self-efficacy Tool) and about their discriminatory attitudes (Quick Discrimination Index).

Results:
The literature review found that educational approaches that solely focus on culture might not be sufficient in addressing discrimination and racism. During consultation, academics emphasised the importance of situating cross-cultural nursing and antidiscrimination as social determinants of health. Therefore, cross-cultural nursing was contextualised within primary health care and emphasised care for culturally diverse communities. Survey findings supported the effectiveness of this strategy in promoting students' confidence regarding knowledge about cross-cultural nursing. There was no reported change in discriminatory attitudes. The teaching and learning approach was modified to include stronger experiential learning and role playing.

Conclusions:
Nursing education should emphasise cross-cultural nursing and antidiscrimination. The study describes an evaluated teaching and learning approach and demonstrates how evaluation research can be used to develop cross-cultural nursing education interventions.

Preserving utility in social network graph anonymization

To protect from privacy disclosure, the social network graph is modified in order to hide the information that potentially be used to disclose person's identity. However, when the social network graph is changed, it is a great challenge to balance between the privacy gained and the loss of data utility. In this paper, we address this problem. We propose a new graph topological-based metric to improve utility preservation in social network graph anonymization. We compare the proposed approach with the amount-of-edge-change metric that popularly used in most of previous works. Experimental evaluation shows that our approach generates anonymized social network with improved utility preservation.

Modeling malware propagation in smartphone social networks

Smartphones have become an integral part of our everyday lives, such as online information accessing, SMS/MMS, social networking, online banking, and other applications. The pervasive usage of smartphones also results them in enticing targets of hackers and malware writers. This is a desperate threat to legitimate users and poses considerable challenges to network security community. In this paper, we model smartphone malware propagation through combining mathematical epidemics and social relationship graph of smartphones. Moreover, we design a strategy to simulate the dynamic of SMS/MMS-based worm propagation process from one node to an entire network. The strategy integrates infection factor that evaluates the propagation degree of infected nodes, and resistance factor that offers resistance evaluation towards susceptible nodes. Extensive simulations have demonstrated that the proposed malware propagation model is effective and efficient.

A qualitative evaluation of online chat groups for women completing a psychological intervention for female sexual dysfunction

Because of the embarrassment that can surround female sexual dysfunctions, online interventions offer an anonymous and private treatment alternative. Recently, an online cognitive-behavioral treatment for female sexual dysfunctions was evaluated. Although significant improvements were observed in sexual functioning, the treatment was primarily a behavioral intervention because of difficulties with engaging participants in cognitive therapy over e-mail. To address this limitation, the use of chat groups was incorporated into a new online treatment for female sexual dysfunctions—the PursuingPleasure program. Thirty-eight women participated in the PursuingPleasure chat groups. The goals of the chat groups were to address and overcome challenges as women progressed through PursuingPleasure and to create a social support network where group therapy processes could be used. The chat groups aimed to address misunderstandings, monitor changes, and receive feedback. A qualitative analysis of the chat groups revealed that they helped to facilitate the cognitive-affective aspects of the program, as well as fulfill their other intended functions. This study demonstrates how the use of chat groups in the online treatment of female sexual dysfunctions is a useful addition to Internet-based treatment. Feedback suggests that the chat groups were one of the most helpful aspects of the program, although a small group of women reported finding the groups unhelpful.

Using theory in criminal justice evaluation

This chapter examines the nature and role of theory in criminal justice evaluation. A distinction between theories of and theories for evaluation is offered to clarify what is meant by ‘theory’ in the context of contemporary evaluation practice. Theories of evaluation provide a set of prescriptions and principles that can be used to guide the design, conduct and use of evaluation. Theories for evaluation include programme theory and the application of social science theory to understand how and why criminal justice interventions work to generate desired outcomes. The fundamental features of these three types of theory are discussed in detail, with a particular focus on demonstrating their combined value and utility for informing and improving the practice of criminal justice evaluation

Unpacking black boxes: Mechanisms and theory building in evaluation

There is growing interest in the concept of ‘‘mechanism’’ across many areas of the social sciences. In the field of program and policy evaluation, a number of scholars have also emphasized the importance of causal mechanisms for explaining how and why programs work. However, there appears to be some ambiguity about the meaning and uses of mechanism-based thinking in both the social science and evaluation literature. In this article we attempt to clarify what is meant by mechanisms in the context of program evaluation by identifying three main characteristics of mechanisms and outlining a possible typology of mechanisms. A number of theoretical and practical implications for evaluators are also discussed, along with some precautions to consider when investigating mechanisms that might plausibly account for program outcomes.

Process evaluation of a community-based intervention program: Healthy Youth Healthy Communities, an adolescent obesity prevention project in Fiji

Nearly one-half of the adult population in Fiji between the ages of 15–64 years is either overweight or obese; and rates amongst school children have, on average, doubled during the last decade. There is an urgent need to scale up the promotion of healthy behaviors and environments using a multi-sectoral approach. The Healthy Youth Healthy Community (HYHC) project in Fiji used a settings approach in secondary schools and faith-based organizations to increase the capacity of the whole community, including churches, mosques and temples, to promote healthy eating and regular physical activity, and to prevent unhealthy weight gain in adolescents aged 13–18 years. The team consisted of a study manager, project coordinator and four research assistants (RAs) committed to planning, designing and facilitating the implementation of intervention programs in collaboration with other stakeholders, such as the wider school communities, government and non-governmental organizations and business partners. Process data were collected on all intervention activities and analyzed by dose, frequency and reach for each specific strategy. The Fiji Action Plan included nine objectives for the school settings; four were based on nutrition and two on physical activity in schools, plus three general objectives, namely capacity building, social marketing and evaluation. Long-term change in nutritional behavior was difficult to achieve; a key contributor to this was the unhealthy food served in the school canteens. Whilst capacity-building proved to be one of the best mechanisms for intervening, it is important to consider the cultural and social factors influencing health behaviors and affecting specific groups.

Process evaluation design and tools used in a kindergarten-based, family-involved intervention to prevent obesity in early childhood. The ToyBox-study

Process evaluation (PE) is used for the in-depth evaluation of the implementation process of health promotion programmes. The aim of the current paper was to present the PE design and tools used in the ToyBox-intervention. The PE design was based on a three-step approach, including the identification of ToyBox-specific PE elements (step 1), the development of PE tools and harmonization of procedures (step 2), and the implementation of PE using standardized protocol and tools across the intervention countries (step 3). Specifically, to evaluate the implementation of the intervention, teachers' monthly logbooks were recorded (dose delivered, fidelity, dose received); post-intervention questionnaires were completed by parents/caregivers and teachers (dose received); participation and attrition rates were recorded (recruitment, reach); and audit questionnaires and retrospective information on weather conditions were collected (physical and social environment within which the intervention was implemented). Regarding the teachers' training sessions, the researchers who performed the trainings completed evaluation forms and documented teachers' attendance after each training (dose delivered, fidelity, dose received) and teachers completed evaluation forms after each training (dose received). The PE performed in the ToyBox-intervention may contribute in the evaluation of its effectiveness, guide the revision of the intervention material and provide insights for future health promotion programmes and public health policy.

Enhancing critical analysis and problem-solving skills in undergraduate psychology: An evaluation of a collaborative learning and problem-based learning approach

Critical analysis and problem-solving skills are two graduate attributes that are important in ensuring that graduates are well equipped in working across research and practice settings within the discipline of psychology. Despite the importance of these skills, few psychology undergraduate programmes have undertaken any systematic development, implementation, and evaluation of curriculum activities to foster these graduate skills. The current study reports on the development and implementation of a tutorial programme designed to enhance the critical analysis and problem-solving skills of undergraduate psychology students. Underpinned by collaborative learning and problem-based learning, the tutorial programme was administered to 273 third year undergraduate students in psychology. Latent Growth Curve Modelling revealed that students demonstrated a significant linear increase in self-reported critical analysis and problem-solving skills across the tutorial programme. The findings suggest that the development of inquiry-based curriculum offers important opportunities for psychology undergraduates to develop critical analysis and problem-solving skills. © 2013 The Australian Psychological Society.

Evaluation of University of Queensland Library Spaces: three case studies at St Lucia Campus

Introduction: The paper reports on an evaluation study of spaces in the Social Sciences and Humanities (SSHL), Biological Sciences (BSL) and Walter Harrison Law (WHLL) Libraries of the University of Queensland (UQ). The study was part of an evaluation of the quality and patterns of use of spaces in UQ libraries, which aimed to propose recommendations for future improvements and decision-making. This paper presents a study of areas of weakness in existing SSHL spaces, and impacts of the refurbishment of spaces at BSL and WHLL on students’ experiences. The findings evidence a link between students’ learning experiences and the quality of library spaces.Methods: An online survey, “Students’ Experiences and Perceptions of Library Physical Spaces”, was designed to collect data from students. The survey questions addressed seven topics: (1) overall satisfaction with spaces in the UQ Libraries; (2) welcoming nature of the library entry; (3) lighting; (4) acoustics; (5) furniture; (6) wayfinding; and (7) preferences for different space types in the library.Results: 1505 students completed the surveys, with 1098 responses recorded to open-ended questions on why students visited the libraries and the physical characteristics of the spaces that influenced their experiences. Quantitative and qualitative analysis of the data elucidated key design challenges and considerations. In particular, the data suggested that the provision of individual quiet study spaces remains an important role of academic libraries, with Studying Alone identified as the most important reason for student visits.Conclusions: The findings highlight the importance of individual study spaces and propose a number of recommendations in relation to physical space design and management.Relevance: Academic libraries face the challenge to keep pace with change in relation to students’ demographics, pedagogy and technology. In doing so, it is important to have an understanding of the evolving patterns of students’ learning behaviours, space uses and preferences through ongoing evaluation of library spaces.
