Linking food literacy to nutrition

“Food literacy” is an emerging term used to describe the relative ability to understand the nature of food and how it is important. It also describes the ability to gather, process, analyse and act upon information about food and to apply it in individual settings. A Delphi study of 43 Australian food experts from diverse sectors and settings in all states and territories explored the meaning of food literacy, its constitutive components and how they relate to nutrition. The three-round Delphi began with a semi-structured telephone interview and was followed by two online surveys. Grounded theory was used to develop a conceptual model of the relationship between food literacy and nutrition. It is proposed that food literacy influences nutrition through three related mechanisms of security, choice and pleasure. These mechanisms will be mediated by the local food supply and individual values. The relative importance of components of food literacy will depend upon these mediators. The level of nutrition outcome being sought (for example, dietary guidelines versus food group serves) will also influence the relative importance of these components. This model will be useful in informing program planning and evaluation and will be tested and refined following a phenomenological study of consumers.

Modeling perceived influences on journalism : evidence from a cross-national survey of journalists

Surveying 1,700 journalists from seventeen countries, this study investigates perceived influences on news work. Analysis reveals a dimensional structure of six distinct domains—political, economic, organizational, professional, and procedural influences, as well as reference groups. Across countries, these six dimensions build up a hierarchical structure where organizational, professional, and procedural influences are perceived as more powerful limits to journalists' work than political and economic influences.

Does gender determine journalists' professional views? A reassessment based on cross-national evidence

Research into journalism and gender to date has found somewhat contradictory evidence as to the ways in which women and men practice journalism. While some scholars claim that women have inherently different concepts and practices of journalism and that this has led to a feminization of journalism, others have found little evidence to suggest that men and women differ significantly in terms of their role conceptions. While numerous studies have been conducted into this issue around the world, few have taken a truly comparative approach. This paper presents results from a large-scale comparative survey into gender differences in journalists’ professional views in 18 diverse countries around the world. Results suggest that women and men do not differ in any meaningful ways in their role conceptions on neither the individual level, in newsrooms dominated by women, nor in socio-cultural contexts where women have achieved a certain level of empowerment.

HPAKE : Password authentication secure against cross-site user impersonation

We propose a new kind of asymmetric mutual authentication from passwords with stronger privacy against malicious servers, lest they be tempted to engage in “cross-site user impersonation” to each other. It enables a person to authenticate (with) arbitrarily many independent servers, over adversarial channels, using a memorable and reusable single short password. Beside the usual PAKE security guarantees, our framework goes to lengths to secure the password against brute-force cracking from privileged server information.

Who struggles most in making a career choice and why?Findings from a cross-sectional survey of highschool students

This paper reports findings from an empirical study examining the influence of student background and educational experiences on the development of career choice capability. Secondary school students attending years 9-12 (N = 706) in New South Wales (NSW), Australia, were invited to participate in an online survey that sought to examine factors influencing their career choices. The survey included questions relating to student demographics, parental occupation, attitudes to school and to learning, student aspirations, and students’ knowledge of the further education or skills required to achieve their desired goal. We found no significant differences in the proportions of students who were “uncertain” of their future career aspirations with respect to their socio-educational background. There were, however, significantly more students struggling with career decision making from an English-speaking background in comparison to households where children spoke a language other than English. Those students were proportionally present in government and non-government schools and had some behavioural and attitudinal characteristics in common.

Unusual cross-ring S(N)2 reactions of M-H (-) ions of methoxyacetanilides

Deprotonated o, m-, and p-methoxyacetanilide show pronounced peaks in their collision-induced tandem mass spectra (MS/MS) produced by losses of the elements of C2H6. It is proposed that this reaction is a 'cross-ring' internal S(N)2 reaction involving an incipient methyl anion. For example, p-CH3O-C6H4-N--CO-CH3--> [(p.CH3O-C6H4-N=C=O)CH3-]--> O---C6H4-N=C=O+C2H6.

Linking research and practice

Understanding the key factors that influence the evidentiary basis for practice and using skills in retrieving evidence that informs practice change are essential to the development of a health professional's career, regardless of the discipline. This chapter focuses on the key links between research and practice, particularly how health professionals use various sources of evidence and new knowledge to inform and improve the effectiveness of their practice in order to benefit the health of clients. Evidence-based practice and research utilisation are two major global research/practice initiatives that form the basis for this chapter. Examples that illustrate the real-world application of these initiatives are included in the Research Alive and Case Study sections. How practice change can be facilitated within health organisations is also briefly introduced.
