Critical appraisal of health literacy indices revealed variable underlying constructs, narrow content and psychometric weaknesses

Objective
Health literacy refers to an individual's ability to seek, understand, and use health information. A range of indices exist that purport to measure health literacy across individuals and populations. This study aimed to review the development and content of existing indices and to critically appraise their properties.

Study Design and Setting
Using standardized search terms, published generic health literacy indices (1990–2008) were identified. Using a methodological framework, each was evaluated for purpose, validity (face, content, construct), reliability, responsiveness, feasibility, and generalizability.

Results
Nineteen instruments were evaluated. Three measurement approaches were identified: direct testing of individual abilities, self-report of abilities, and population-based proxy measures. Composition of underlying constructs and content varied widely across instruments, and none appeared to fully measure a person's ability to seek, understand, and use health information. The content was focused primarily on reading comprehension and numeracy; scoring categories were poorly defined and may not be mutually exclusive, and few indices had been assessed for reliability.

Conclusion
Health literacy is not consistently measured, making it difficult to interpret and compare health literacy at individual and population levels. Empirical evidence demonstrating validity and reliability of existing indices is required, and more comprehensive health literacy instruments need to be developed.

Post global financial crisis international business strategies

International business strategies are affected by economic conditions, although the resource-based view would suggest that company resources are a more significant factor. This paper identifies differences in the international strategy behaviours of companies located in countries which, as a result of the GFC, entered either a deep recession, a shallow recession or no recession at all. Empirical evidence is provided for companies with home country markets with each of these conditions. The ability of international strategy theories to explain these behaviours is considered. Based on observations of international businesses with home country markets in each of these categories, it is suggested that determinants of international strategy during financial crises (and immediately after) are influenced by the strength of the home country market, foreign market government protectionist behaviour, international exchange rate variations and local levels of rivalry.

Tracking of sedentary behaviours of young people : a systematic review

Objective : To review the empirical evidence concerning the strength of tracking of sedentary behaviours from childhood and adolescence.

Methods : Published English language studies were located from computerised and manual searches in 2009. Included studies were prospective, longitudinal studies with at least one sedentary behaviour for at least two time-points, with tracking coefficients reported, and included children (aged 3–11 years) and adolescents (12–18 years) at baseline.

Results : Based on data from 21 independent samples, tracking coefficients (r) ranged from 0.08 (over 16 years) to 0.73 (over 2 years) for TV viewing, from 0.18 (boys over 3 years) to 0.52 (over 2 years) for electronic game/computer use, from 0.16 (girls over 4 years) to 0.65 (boys over 2 years) for total screen time, and from −0.15 (boys over 2 years) to 0.48 (over 1 year) for total sedentary time. Study follow-up periods ranged from 1 to up to 27 years, and tracking coefficients tended to be higher with shorter follow-ups.

Conclusions : Sedentary behaviours track at moderate levels from childhood or adolescence. Data suggest that sedentary behaviours may form the foundation for such behaviours in the future and some may track slightly better than physical activity.

Brand salience for fast-moving consumer goods : an empirically based model

Brand salience, or the prominence of a brand in memory, has been linked to brand choice and purchase by consumers. The research reported in this paper proposed and tested a model of brand salience for fast-moving consumer goods, which incorporates knowledge, media consumption, and brand image as antecedents. A quasi-experimental method was utilised, where 270 respondents undertook a free recall exercise using category cues, and then completed multiitem measures of brand knowledge, brand associations, and purchase likelihood. Analysis of the data using SEM found support for an empirical model of brand salience where there was a relationship between brand salience and purchase likelihood. The empirical evidence supports building a brand in a primary category, in order to build the depth and breadth of the brand’s associations in consumer memory.

Is healthy behavior contagious : associations of social norms with physical activity and healthy eating

Background
Social norms are theoretically hypothesized to influence health-related behaviors such as physical activity and eating behaviors. However, empirical evidence relating social norms to these behaviors, independently of other more commonly-investigated social constructs such as social support, is scarce and findings equivocal, perhaps due to limitations in the ways in which social norms have been conceptualized and assessed. This study investigated associations between clearly-defined social norms and a range of physical activity and eating behaviors amongst women, adjusting for the effects of social support.

Methods
Self-report survey data about particular physical activity (leisure-time moderate-vigorous activity; volitional walking; cycling for transport) and eating behaviors (fast food, soft drink and fruit and vegetable consumption), and social norms and support for these, were provided by 3,610 women aged 18-46 years living in socioeconomically disadvantaged neighborhoods in Victoria, Australia.

Results
Results of regression analyses showed that social norms for physical activity and eating behaviors predicted these respective behaviors relatively consistently; these associations generally remained significant after adjustment for social support.

Conclusions
Acknowledging the cross-sectional study design, these data confirm theoretical accounts of the importance of social norms for physical activity and eating behaviors, and suggest that this is independent from social support. Intervention strategies aimed at promoting physical activity and healthy eating could incorporate strategies aimed at modifying social norms relating to these behaviors.

A practical approach to achieving agility : a theory of constraints perspective

This article documents an action research (AR) project aimed at identifying the practical steps needed to become an agile manufacturer through a combination of the theory of constraints (TOC) and resource- based view (RBV) approaches in a small to medium enterprise (SME) in the Australian manufacturing sector. To date, lean production has been highlighted as a possible catalyst for creating an agile manufacturer, despite the evidence suggesting that lean manufacturing lacks the responsiveness and adaptability to effectively handle a rapidly changing market place and only works well in a stable environment. A more flexible system of production is required to fully encompass the agile characteristics needed to attain a competitive advantage. This research provides empirical evidence that the TOC perspective can be used as a practical approach for becoming an agile manufacturer. The study provides a workable approach for small firms to achieve ‘Agility’ in practice.

Developing negotiation decision support systems that support mediators : a case study of the Family_Winner system

Negotiation Support Systems have traditionally modelled the process of negotiation. They often rely on mathematical optimisation techniques and ignore heuristics and other methods derived from practice. Our goal is to develop systems capable of decision support to help resolve a given dispute. A system we have constructed, Family_Winner, uses empirical evidence to dynamically modify initial preferences throughout the negotiation process. It sequentially allocates issues using trade-offs and compensation opportunities inherent in the dispute.

Developing a scholarly approach to the evaluation of assessment practices

Purpose – The purpose of this paper is to examine and reflect on current assessment practice in a large undergraduate accounting programme delivered both in Australia and offshore, from the perspective of academics in their first semester at a “new-to-them” university.

Design/methodology/approach – The changing higher education environment and the reality of assessment in the current context are considered, as they raise a number of important issues around assessment practice. Some of the often cited literature linking teaching, learning and assessment, including student-centred learning and Confucian heritage culture, is also discussed. A reflective approach is used where Säljö's five categories of student learning are used as the basis for informed reflection of the assessment used in the “new” academics' first semester at the university. The use of empirical evidence to test these reflections would be the next step in this scholarly approach to teaching and learning.

Findings – The reflections reveal a disparity between reality and the ideal in relation to assessment practice. Issues regarding timely feedback to students and timing of assessments can result in summative assessment when it has the potential to be formative. This paper has provided an opportunity for “new” academics to engage with the higher education literature early in their careers.

Originality/value – This paper is a resource for academics beginning to engage with the higher education literature around assessment, teaching and learning and can also be used to inform and improve the teaching and learning practices of many academics in higher education.

Does the polygraph lead to better risk prediction for sexual offenders?

The polygraph is receiving increased attention surrounding its ability to facilitate more honest disclosures from sexual offenders concerning risk-related information (e.g., historical risk factors and acute-dynamic risk factors). In addition, the polygraph has become accepted as a standard containment tool in the US, although UK professionals appear to have taken a more cautionary approach. The aim of this review is to provide a basic overview of current risk assessment procedure in the absence of the polygraph, and then to investigate studies that use the polygraph to enhance sexual offenders' risk assessments. Specifically, studies examining historical risk factors, stable-dynamic risk factors, and acute-dynamic risk factors are examined and evaluated. We conclude that there is reasonable evidence supporting polygraph use in some areas of risk assessment. However, the vast majority of studies suffers from serious confounds that should be taken into account by professionals who use the polygraph as a standard practice in sexual offender risk assessment and management. Finally, the future of the polygraph is discussed in light of the presented empirical evidence.

Relapse prevention : a critique and proposed reconceptualisation

Relapse prevention (RP) plays a significant role in current treatments and post-treatment approaches to substance abuse problems. It is also widely used in a number of other problem areas, including other addictive behaviours and sexual offending. The widespread use of RP in various fields is due to both its clearly articulated theoretical basis, which has significant face validity, and its transferability into clinical practice. Also, there is a growing (though arguably still modest) body of empirical evidence that demonstrates its efficacy in a range of therapeutic contexts. However, arguably, in terms of both the theoretical underpinnings and the practical application of RP there is room for improvement. This article hypothesises that one of the key weaknesses of RP is that it takes a generally unconstructive approach to the therapeutic process through the use of negative concepts and avoidance goals. It is suggested that a 'good lives' framework of psychological wellbeing can provide a means of remedying these weaknesses of the traditional RP model. It is argued that a good lives framework can lead to a more optimistic approach to the prevention of relapse among individuals with substance use problems.

Restorative justice and the human rights of offenders : convergences and divergences

Restorative justice has gained significant momentum as a justice reform movement within the past three decades, and it is estimated that up to one hundred countries worldwide utilize restorative justice practices. Although claims about the role of restorative justice in protecting human rights are repeatedly made in the restorative justice literature, they are seldom supported by empirical evidence or a thorough analysis of human rights and their justification. In this paper, we discuss how the assumptions underpinning restorative justice practices impact on offenders' human rights, and their points of convergence and divergence. We argue that while these assumptions can protect certain offender rights, they may violate others. We finish with some suggestions about how to reconcile the tensions between human rights and restorative justice, focusing in particular on the relationship between community needs and individual well-being.

Parental nurturing and adverse effects of redistribution

This paper suggests that if parental nurturing is a dominating force in human capital formation then income redistribution may not promote economic growth. In particular, if, consistently with empirical evidence, parental human capital complements investment in a child’s education and yields increasing returns in the intergenerational production of human capital, income redistribution may have an adverse impact on the growth rate of average human capital. Redistribution shifts resources towards the less educationally-productive families and thus in the presence of credit markets imperfections and increasing returns, it reduces the aggregate level of investment in human capital. Moreover, if the degree of increasing returns is sufficiently large to produce sustained growth, this adverse effect on human capital formation may outweigh the conventional beneficial effects of redistribution that arises from the interaction between a production technology exhibiting diminishing returns and credit market imperfections.

Modelling behavioural and fitness consequences of disturbance for geese along their spring flyway

1. For migratory birds the implications of environmental change may be difficult to predict because they use multiple sites during their annual cycle. Moreover, the migrants’ use of these sites may be interdependent. Along the flyway of the Svalbard pink-footed goose Anser brachyrhynchus population, Norwegian farmers use organized scaring to minimize goose use of their grasslands in spring. We assessed the consequences of this practice for regional site use of pink-footed geese along their spring migration route.

2. We used dynamic programming to find the sequence of migratory decisions that maximizes the fitness of female geese during spring migration, assuming scaring impinges on both food-intake rates and predation risk. The parameterization of the model was based on data gathered from individually marked pink-footed geese between 1991 and 2003.

3. The effect of scaring in terms of fitness and site use was most noticeable regarding food-intake rate. Scaring resulted in a redistribution of geese along the flyway. Furthermore, the outcomes of the modelling exercises were highly dependent on whether or not the geese were omniscient or naive: at moderate scaring levels naive geese were predicted to succumb.

4. On a qualitative basis there was good correspondence between the predictions from the model and the empirical evidence gathered to date.

5. Synthesis and applications. Besides highlighting the importance of learning and changing behaviour in an adaptive fashion, our modelling exercise indicated the potential vulnerability of the geese to abrupt environmental change. In addition, the exercise emphasized the interdependence of site use along the migratory flyway. The model supports the necessity for an integrated flyway management approach. In Norway, discussion is ongoing about the future management of the spring conflict between farming interests and geese. Farmers in north and mid-Norway have announced that they will expand the scaring campaign if a long-term solution, including a compensation scheme, is not forthcoming. If scaring on such a large scale is implemented abruptly, it may have severe consequences for the population: management of both the scaring intensity and its geographical extent is urgently required.

Value relevance of accounting information in China pre- and post-2001 accounting reforms

Purpose – This paper aims to investigate whether the accounting reform in China has improved the relevance of China's accounting information. It seeks to investigate the association between earnings and book value of equity to share returns before and after the introduction of the Accounting System for Business Enterprises (ASBE) in 2001 for A- and A&B-share firms.

Design/methodology/approach – The paper employs the return regression model. The pre-ASBE period is designated as 1997 through to 2000, and the post-ASBE period is designated as 2002 through to 2004. All firms listed on the Chinese stock market during the investigation period constitute the sample.

Findings – It is found that accounting information better explains share returns for both A-share firms and A&B-share firms in the post-ASBE period. The paper also finds that the book value of equity for A&B-share firms is incrementally value relevant to that of A-share firms in the post-ASBE period.

Research limitations/implications – Further studies will contribute to understanding how governance mechanisms and liquidity influence the association between accounting information and share returns in the Chinese A-share market.

Practical implications – The findings provide empirical evidence regarding the relevance of accounting information in emerging markets.

Originality/value – The paper contributes to the extant value relevance literature by investigating time periods surrounding the issue of ASBE in 2001 in the Chinese stock market.

Inbreeding level does not induce female discrimination between sibs and unrelated males in guppies

Significant empirical evidence has demonstrated the importance of discriminative mate choice as a mechanism to avoid inbreeding. Incestuous mating can be avoided by recognition of kin. The guppy, Poecilia reticulata, is a livebearer with a polygamous mating system and active female choice. Despite potential inbreeding costs in the guppy, Viken et al. (Ethology 112:716–723, 2006) and Pitcher et al. (Genetica 134:137–146, 2008) have found that females do not discriminate between sibs and unrelated males. However, populations experiencing different inbreeding histories can have different levels of inbreeding avoidance, and it is possible that the lack of inbreeding avoidance observed in guppies is a consequence of using outbred fish only. Here we tested the preference of female guppies with different inbreeding coefficients, for olfactory cues of males that were either unrelated but had the same inbreeding coefficient, or were related (i.e. brother) with the same inbreeding coefficient. We found no evidence that female guppies preferred unrelated males with the same inbreeding coefficient. Moreover, inbreeding level did not influence female preference for unrelated males, suggesting that inbreeding history in a population has no influence on female discrimination of unrelated males in guppies.
