Risk Factors for Cognitive Impairment in Adults Attending Australian Community‐Based Substance Use Treatment Services
Online survey data integrity
A notable and growing risk in online research is fraudulent respondent activity using artificial intelligence. Given that researchers often rely on anonymous recruitment methods to reach hidden and diverse populations, it is essential to develop contextualised anti-bot protocols sensitive to research scale, topic and population, allowing sufficient data to be collected while detecting bot activity and safeguarding data integrity. This paper repor…
Nutrient Dense, Low-Cost Foods Can Improve the Affordability and Quality of the New Zealand Diet—A Substitution Modeling Study
The high prevalence of non-communicable disease in New Zealand (NZ) is driven in part by unhealthy diet selections, with food costs contributing to an increased risk for vulnerable population groups. This study aimed to: (i) identify the nutrient density-to-cost ratio of NZ foods; (ii) model the impact of substituting foods with a lower nutrient density-to-cost ratio with those with a higher nutrient density-to-cost ratio on diet quality and affo…
Diet and Economic Modelling to Improve the Quality and Affordability of the Australian Diet for Low and Medium Socioeconomic Households
Food costs are a barrier to healthier diet selections, particularly for low socioeconomic households who regularly choose processed foods containing refined grains, added sugars, and added fats. In this study, the objectives were to: (i) identify the nutrient density-to-cost ratio of Australian foods; (ii) model the impact of substituting foods with lower nutrient density-to-cost ratio with those with the highest nutrient density-to-cost ratio fo…
Vegetable intake in Australian children and adolescents
Objective: We aimed to profile vegetable consumption and its association with dietary and sociodemographic factors. Design: Secondary analysis of a nationally representative nutrition survey. ‘Vegetables’ refers to non-discretionary ‘vegetables and legumes/beans’ as defined by the Australian Dietary Guidelines (ADG). Prevalence of vegetable consumption, frequency of intake, proportion meeting ADG recommendations, most popular food groups, intake …
Discretionary intake among Australian adults
Objective To profile discretionary food and beverage (DF) consumption among Australian adults. Design Cross-sectional analysis. Dietary and sociodemographic data were used to profile DF intake. Prevalence of DF consumption, DF servings (1 serving=600 kJ), nutrient contribution from DF and top DF food groups by self-reported eating occasions were determined. DF consumers (>0 g) were classified according to quartile of DF intake and general linear …
Acquisition of nominal morphophonological alternations in Russian
Morphophonological alternations can make target-like production of grammatical morphemes challenging due to changes in form depending on the phonological environment. This article explores the acquisition of morphophonological alternations involving the interacting patterns of vowel deletion and stress shift in Russian-speaking children (aged 4;0–7;11) using a ‘wug’ test with real and nonce words. Depending on the phonological context, participan…
Creative workers’ views on cultural heritage and sustainability
This paper presents the “Arts–Sustainability–Heritage” (ASH) model which may be used to understand the values and actions of creative workers in relation to cultural heritage and sustainability. The model is derived from previous research on conceptions of sustainability, and the qualitative data comes from the “Creative Workforce” survey. We contend that artistic work is essential both for cultural heritage through the work's reference and re-in…
Factors leading to the adoption of a learning technology
This paper reports on a case study which examined factors leading to the adoption of graphics calculators (GCs) by secondary mathematics teachers in the state of New South Wales, Australia. In total, 587 teachers of the General Mathematics Course (Years 11 and 12) participated in the study. The median teachers' stage of adoption of GCs was found to be at the "Understanding and application of the process" level, the third lowest on a six point sca…
Educators' conceptions of student diversity in their classes
This article reports on an international study investigating university educators' ideas about the diversity of their students, carried out by using semi‐structured email interviews. The information obtained from participants was analysed using a phenomenographic approach to obtain an outcome space, in which the narrowest conception ignored any differences between students, the broader conceptions made allowance for such differences, while the mo…
Research interviews in cyberspace
Contemporary developments in technology provide opportunities for qualitative researchers to enhance their modes of collecting rich data for analysis. In this article we explore the utility and impact of using email as a means of collecting data in the form of semi‐structured interviews. We investigate what participants think about email interviews, and how they view the relationship between email interviews and online pedagogies. We illustrate o…

Identity and engagement for professional formation
Students enter university with ideas about their future professions. In some disciplines, the profession and the nature of professional work are well understood, while in other areas, they are more opaque. The authors investigate the ways in which students develop a sense of identity with their profession, how the nature of the profession impacts on identity formation, how students engage with learning based on their professional expectations, an…

Relationship between learning outcomes and online accesses
This paper reports on a study carried out in Thailand investigating the relationship between students' use of an e-learning system and their learning outcomes in a course on Business Statistics. The results show a clear relationship between accesses to the e-learning system, as measured by number of "hits", and outcomes, as measured by final results. While the results do not establish a direct casual connection, they indicate that under appropria…
Synthetic Indices
Demands are increasingly being placed on aid agencies to demonstrate impact, but the measurement and attribution of non-tangible changes in complex environments are problematic. Synthetic indices are frequently used by statisticians in other contexts to capture complex changes and may prove useful to describe changes effected by aid projects. A hierarchy of hypotheses is presented to describe a case-study project. The construction of synthetic in…
Factors Influencing Young People's Conceptions of Environment
Environmental education in schools is an important strategy in achieving environmental protection and improvement. However, it needs to be based on children's understandings of environment rather than on assumptions of what children know and believe. In a previous article (Loughland et al ., 2002), we reported on a research project where school children's responses to an open-ended statement 'I think the term/word environment means' were analysed…
