Applications of nutrient profiling : potential role in diet-related chronic disease prevention and the feasibility of a core nutrient-profiling system

Background/objectives: A number of different nutrient-profiling models have been proposed and several applications of nutrient profiling have been identified. This paper outlines the potential role of nutrient-profiling applications in the prevention of diet-related chronic disease (DRCD), and considers the feasibility of a core nutrient-profiling system, which could be modified for purpose, to underpin the multiple potential applications in a particular country.

Methods: The ‘Four ‘P’s of Marketing’ (Product, Promotion, Place and Price) are used as a framework for identifying and for classifying potential applications of nutrient profiling. A logic pathway is then presented that can be used to gauge the potential impact of nutrient-profiling interventions on changes in behaviour, changes in diet and, ultimately, changes in DRCD outcomes. The feasibility of a core nutrient-profiling system is assessed by examining the implications of different model design decisions and their suitability to different purposes.

Results and conclusions: There is substantial scope to use nutrient profiling as part of the policies for the prevention of DRCD. A core nutrient-profiling system underpinning the various applications is likely to reduce discrepancies and minimise the confusion for regulators, manufacturers and consumers. It seems feasible that common elements, such as a standard scoring method, a core set of nutrients and food components, and defined food categories, could be incorporated as part of a core system, with additional application-specific criteria applying. However, in developing and in implementing such a system, several country-specific contextual and technical factors would need to be balanced.

Clinical nurse research consultant : a clinical and academic role to advance practice and the discipline of nursing

Aims:  This article presents a proposal for the Clinical Nurse Research Consultant, a new nursing role. Background:  Although healthcare delivery continues to evolve, nursing has lacked highly specialized clinical and research leadership that, as a primary responsibility, drives evidence-based practice change in collaboration with bedside clinicians. Data sources:  International literature published over the last 25 years in the databases of CINAHL, OVID, Medline Pubmed, Science Direct, Expanded Academic, ESBSCOhost, Scopus and Proquest is cited to create a case for the Clinical Nurse Research Consultant. Discussion:  The Clinical Nurse Research Consultant will address the research/practice gap and assist in facilitating evidence-based clinical practice. To fulfil the responsibilities of this proposed role, the Clinical Nurse Research Consultant must be a doctorally prepared recognized clinical expert, have educational expertise, and possess advanced interpersonal, teamwork and communication skills. This role will enable clinical nurses to maintain and share their clinical expertise, advance practice through research and role model the clinical/research nexus. Implications for nursing:  Critically, the Clinical Nurse Research Consultant must be appointed in a clinical and academic partnership to provide for career progression and role support. Conclusion:  The creation of the Clinical Nurse Research Consultant will advance nursing practice and the discipline of nursing.

Visualising literature : screen adaptation and the process of reading/viewing

This study demonstrates a method of reading/viewing screen adaptations of literary works as intertextually situated works of art which interact through differences to make possible new interpretations. Switching between possible interpretations undermines views of the world which critics find embedded in the screen adaptation and literary precursors.

The strange and the familiar : seeing beyond when we know

My novel is a collection of interrelated stories. Each story is framed by the idiosyncrasies and prejudices of a different first-person voice. There are gaps in narrative time and there is disparity between the narrators’ voices. The result is a ‘discontinuous narrative’; this term describes the early work of Frank Moorhouse: ‘an innovative narrative method using interconnected stories’ (Griffith University 2011).
As I draft and re-draft the stories, I am forced to assess the interaction between the voices. I am aware of the disjuncture, and I ask myself: Why not tell the story through the eyes of one narrator? Why not choose a third-person perspective, an omniscient narrator who might collect all of the voices together, in a coherent way?
As I second-guess my approach, I realise that the splintering of voices feels like the right way to tell the story and, in this way, I approach the question of methodology. I am aware that a sense of disjuncture arises out of the medley of voices, but I also realise that the disjuncture is carefully constructed; it is not accidental. This is an intuitive judgement.
If I edit my novel ethically, I ask what the discontinuity achieves, rather than how it fails in the context of logic. This means that I recognise that the narrative begins from a place that does not worry about logic, and I realise that second-guessing the surface content of the narrative, from a rational perspective, may be counterproductive.
The conscious mind, fettered as it is with inhibitions, may fail to see that the logical track is not necessarily the most productive route. The conscious mind may not recognise that going off-track is the way forward and, perhaps, the only way that the story can become something other than what I, in my rational mind, believe that it should be.
Ethical editing means that I am attentive to my intuitive response to the narrative; it means that I tolerate incongruous elements of the narrative, even if they do not fit the criteria of logic.
Ethical editing is a meeting of minds (both mine); the fully conscious mind meets the work of the subconscious mind with surprise and approval, at best, skepticism and derision, at worst. The work of the subconscious mind is elusive but it need not be subjugated to logical, rational considerations, for this means that I delimit the work of the subconscious; it means I assess the discontinuity on the basis of an external operating system; it means that I impose certain criteria upon the surface narrative, criteria that has nothing to do with understanding why the discontinuity exists in the first instance.
Alternatively, when I pay heed to a primal moment of narrative composition, a moment that is not necessarily consciously determined or logical, I apprise the surface of the narrative as a metaphorical map, I attempt to engage with the possibilities for meaning that the map encompasses; this constitutes a quest for the unstable how of meaning attribution.

Influence of atmospheric helium plasma on the surface energy of jute fibres and the performance of resulting composites

In this work, an atmospheric pressure glow discharge helium plasma treatment was employed to modify the surface properties of jute fibres. The resulting bio-composites showed an increase in flexural properties and interlaminar shear strength (ILSS) compared to composites produced using untreated jute fibres. To understand the reason behind the ILSS improvement, the acid–base properties of jute fibres were determined by contact angle analysis using the capillary rise method. The results were fitted further to van Oss–Chaudhury–Good (vOCG) and Chang–Qin–Chen (CQC) models to determine the Lifshitz–van der Waals (LW) and acid–base components of surface energy. Surface energy determined by the vOCG model revealed that plasma treatment of jute fibre resulted in a 22% increase in total surface energy, a 19% increase in the LW component and a 24% increase in the acid–base component of surface energy. The increase in the acid–base component is due to the significant increase (69%) in the electron-accepting (γ+S) parameter. On the other hand, the CQC model clearly indicates an amphoteric nature of the fibre surface based on opposite signs of the acid and base principal values (PSa and PSb). Overall, the results indicated that increases in both LW and acid–base components were responsible for improvement in the properties of the composites.

Privacy and the access of information in a smart house environment

In this paper we present a framework for addressing privacy issues raised by the monitoring of assisted living smart house environments. In home environments, the conflict between the goals of the surveillance, and the private nature of the home, raises the issue of occupant privacy. This issue needs to be addressed if applications are to be accepted by the occupant. We identify four key properties required for the design of privacy sensitive ubiquitous computing applications. Subsequently, we develop a dynamic and flexible method for implementing privacy measures through controlling access to data, and an interface to provide feedback to the occupant, enabling them to control the implemented privacy measures. We form a generic framework for implementing privacy sensitive ubiquitous computing applications based on previous applications within the field. This framework was then extended and used to develop a specific framework for a privacy sensitive smart house. The approach proposed in the framework dynamically applies privacy measures to multi-modal data according to the situation, or context, of the environment. We further test an implementation of the privacy measures, and detail methods to implement feedback and control. The approach aims to decrease the invasiveness of the surveillance, while retaining the purpose of the assisted living environment.

Vitamin D and the musculoskeletal health of older adults

The scientific literature related to vitamin D and bone health in older adults is extensive.

This article aims to summarise key practice points regarding vitamin D and bone health in older adults, relevant to general practitioners, and to provide an overview of the background literature to enable GPs to appreciate the extent of the supporting evidence.

Vitamin D supplementation can prevent falls, particularly in the vitamin D deficient elderly. However, adequate vitamin D levels and dietary calcium intake are needed for effective primary fracture prevention with greatest benefits occurring in the elderly with vitamin D deficiency and/or low dietary calcium intakes. For secondary fracture prevention, ie. preventing further fractures in the elderly who have already sustained a fragility fracture, specific anti-osteoporosis treatment is necessary. However, to maximise the benefits of these medications, vitamin D deficiency should be corrected and adequate dietary calcium consumed.

Teaching primary science : emotions, identity and the use of practical activities

This paper uses cultural historical activity theory to examine the interactions between the choices primary teachers make in the use of practical activities in their teaching of science and the purposes they attribute to these; their emotions, background and beliefs; and the construction of their identities as teachers of science. It draws on four case studies of science lessons taught over a term by four exemplary teachers of primary science. The data collected includes video recordings of science lessons, interviews with each teacher and some of their students, student work, teachers’ planning documents and observation notes. In this paper, we examine the reflexive relationship between emotion and identity, and the teachers’ objectives for their students’ learning; the purposes (scientific and social) the teachers attributed to practical activities; and the ways in which the teachers incorporated practical activities into their lessons. The findings suggest that it is not enough to address content knowledge, pedagogy and pedagogical content knowledge in teacher education, but that efforts also need to be made to influence prospective primary teachers’ identities as scientific thinkers and their emotional commitment to their students’ learning of science.

Organised crime in ports and the isps code: where to now?

In a previous Strategic Insights article [issue no.31, March 2011]  there was a focus on increasing use of maritime shipping containers by drug traffickers pointing to their use as a transport method. This raised the quetion of the extent to which counterterrorism efforts that have raised security levels in ports, as part of a general heightening of security levels. This article questions whether current counterterrorism arrangements on the landside of ports can be effective tools against the presence of organised crime.

Oral language competence, young speakers and the Law

Purpose: This paper highlights the forensic implications of language impairment in 2 key (and overlapping) groups of young people: identified victims of maltreatment (abuse and/or neglect) and young offenders.

Method: Two lines of research pertaining to oral language competence and young people's interface with the law are considered: 1 regarding investigative interviewing with children as victims or witnesses in the context of serious allegations of sexual abuse, and the other pertaining to adolescent offenders as suspects, witnesses, or victims. The linguistic demands that forensic interviewing places on these young people are also considered. Literature concerning the impact of early maltreatment on early language acquisition is briefly reviewed, as is the role of theory of mind in relation to the requirements of investigative interviewing of children and adolescents.

Implications: High-risk young people (i.e., those who are subject to child protection orders because of suspected or confirmed maltreatment, and those who are engaged with the youth justice system) face an elevated risk for suboptimal language development but may need to draw on their language skills in high-stakes forensic interviews. Implications for early intervention policy and practice are identified, and the need for greater speech-language pathology advocacy and engagement in forensic interviewing research is emphasized.

Identification of nonlinear fMRI models using Auxiliary Particle Filter and kernel smoothing method

Hemodynamic models have a high potential in application to understanding the functional differences of the brain. However, full system identification with respect to model fitting to actual functional magnetic resonance imaging (fMRI) data is practically difficult and is still an active area of research. We present a simulation based Bayesian approach for nonlinear model based analysis of the fMRI data. The idea is to do a joint state and parameter estimation within a general filtering framework. One advantage of using Bayesian methods is that they provide a complete description of the posterior distribution, not just a single point estimate. We use an Auxiliary Particle Filter adjoined with a kernel smoothing approach to address this joint estimation problem.

Mentoring and the transfer of organizational memory within the context of an aging workforce : cultural implications for competitive advantage

Organizational memory, the knowledge gained from organizational experience, has significant potential for competitive advantage. Many authors in the knowledge management and human resource management literatures consider mentoring to be a particularly effective method of transferring organizational memory. In addition, older workers are often considered ideal mentors in organizations because of their experience and alleged willingness to pass on their knowledge to less experienced employees. There is an associated assumption that these workers also anticipate and experience positive outcomes when mentoring others. This chapter considers whether these assumptions hold up in the workplaces of the 21st century, particularly within Western countries. Individualistic cultural norms and some discriminatory practices towards older workers, along with a changing career contract that no longer guarantees employment in one organization for life, may discourage knowledge sharing in organizations. This chapter discusses the constraints and motivations that may operate when older experienced workers consider mentoring others. It considers relevant global and organizational cultural characteristics that may influence mentoring to transfer knowledge, and accordingly suggests strategies for those eager to capitalise on the knowledge experienced employees possess.

Experiences of migration and the determinants of obesity among recent Iranian immigrants in Victoria, Australia

Objectives. There is evidence to suggest that immigrant groups from low- or medium-human development index countries show a significant adoption of obesogenic behaviors and experience weight gain following migration to Australia. The objective of this study is to understand the changes that Iranian immigrants experience in relation to the determinants of obesity after migration to Victoria, Australia.

Design. We conducted five focus group discussions with 33 recent Iranian immigrants. This study took an interpretive qualitative approach to data analysis using the constant comparative method.

Results. Participants discussed individual level acculturation (e.g., in diet, body size, attitudes), as well as environmental level changes (e.g., physical/structural and sociocultural) that occurred after immigration. Stress during the initial immigration transition, which affected diet and physical activity habits, was a common experience among participants. Gender and the effect of political/religious changes were also important factors. Participants' discourse largely focused on their ability and willingness to adopt positive health behaviors after migration.

Conclusion. This study provides insight into the effect of migration on the determinants of obesity among Iranian immigrants in Victoria, Australia, and offers a contrast with the existing evidence by considering the experience of a group that is generally well educated, often emigrates for reasons related to personal freedom as opposed to material deprivation, and has rates of obesity similar to high-income countries.

Solvent induced changes in the conformational state of β-lactoglobulin and the influence of protic ionic liquids

The protic ionic liquids (pILs), triethylammonium acetate, triethylammonium trifluoroacetate, triethylammonium mesylate and trimethylammonium sulfate were used to induce various native and non-native conformational states of the protein β-lactoglobulin (βLG). Changes in the secondary structure of βLG were observed on moving from a high water content to a high pIL content. We examined the stability of various pIL induced states via thermal unfolding and refolding, where it was found that at a given pIL concentration a highly stable non-native conformation was formed. The βLG non-native conformation was characterized by a high α-helical content. Additionally, pIL conditions that promoted amyloid fibril formation were identified and characterized by CD, a Thioflavin T binding assay and transmission electron microscopy (TEM). This work highlights the use of pILs as solvents in the study of protein folding using βLG as a model system.
