AbstractTreatment response heterogeneity and individual responses following exercise training are topics of interest for personalized medicine. Proposed methods to determine the contribution of exercise to the magnitude of treatment response heterogeneity and categorizing participants have expanded and evolved. Setting clear research objectives and having a comprehensive understanding of the strengths and weaknesses of the available methods are vital to ensure the correct study design and analytical approach are used. Doing so will ensure contributions to the field are conducted as rigorously as possible. Nonetheless, concerns have emerged regarding the ability to truly isolate the impact of exercise training, and the nature of individual responses in relation to mean group changes. The purpose of this review is threefold. First, the strengths and limitations associated with current methods for quantifying the contribution of exercise to observed treatment response heterogeneity will be discussed. Second, current methods used to categorize participants based on their response to exercise will be outlined, as well as proposed mechanisms for factors that contribute to response variation. Finally, this review will provide an overview of some current issues at the forefront of individual response research.

Purpose – This research aims to explore the factors that lead to the prevalence of the green gap. Currently, an overwhelming majority of consumers voice concern about the state of the environment; however, only a select few mirror their intentions with actual green behaviors. Design/methodology/approach – A critical incident technique is utilized in the first study, followed by a quantitative study analyzed via cluster analysis for the second study. Findings – Results suggest the green gap exists for several reasons, of which price is most commonly noted. However, factors such as poor perceptions of quality, lack of green product availability and brand loyalty to conventional products appear to be important issues leading to the gap as well. Additionally, the type of product sought for purchase appears to impact the prevalence of the green gap. Research limitations/implications – Future research should seek to extend the present study by monitoring actual usage rather than intentions, as well as an examination of strategies that may help to minimize the green gap. Practical implications – Consumers need to understand why green products are priced higher, the benefits they offer and the impact they can make as an individual. Additionally, firms competing in specific product categories can alter their strategies to better capitalize on the motivations of their target markets. Originality/value – Past research has focused on why consumers buy green, but there is a lack of research on why consumers fall into the green gap – that is they have the intention of going green, but don’t. This research examines factors surrounding the green gap and the role of product type in the prevalence of the green gap.

Purpose While country image consists of two hierarchical images – macro country image at the country level and micro country image at the specific product level – previous studies have largely failed to detail its varying effects by product category and by the level of a country’s economic development. The purpose of this paper is to examine the impact of the macro and micro country images of four countries (USA, Italy, Korea, and Malaysia) on Saudi consumers’ purchase intentions in two product categories (symbolic and functional product). Design/methodology/approach Data were collected from shoppers older than 20 years of age at several shopping malls in Riyadh, Saudi Arabia via mall intercept method. Findings Analyses of 496 data revealed that the effects of macro and micro country images differ by product category. In particular, both macro and micro country images were equally relevant to the purchase intention of symbolic goods (i.e. handbags), while micro country image played a greater role in the purchase intention of functional goods (i.e. cell phones). A partial country moderating effect was found. The effects of micro country image on the purchase intention of handbags were valid only in Italy, where product-country match is high. Originality/value This study advances country image research by highlighting how the effects of macro and micro country images on purchase intention differ by product category and by country. The findings suggest which aspect of country image (i.e. macro vs micro) should be actively communicated in the marketing of symbolic and functional goods.

Proposed Model ◽  
The Impact

Purpose This paper aims to present a model linking price promotions to checkout donations. It is argued that price promotions evoke two perceptions/emotions, namely, feelings of gratitude and perceived sacrifice of purchase, which consequently, influence the likelihood to donate. Feelings of gratitude dominate when the discount is high, while feelings of sacrifice dominate when the discount is low. Compared to no-discount situations, high discounts enhance consumers’ intention to donate while low discounts reduce this intention. Design/methodology/approach A total of four studies using shopping scenarios are conducted. Study 1 examines the main effect and the mediating factors. Study 2 replicates the findings in different product categories and at different unit-price levels. Studies 3 and 4 test the moderating effects of customer effort and discount framing. Findings Findings of the four studies provide support for the proposed model. Compared to no-discount situations, high discounts enhance consumers’ intention to donate, while low discounts reduce this intention. The effects are mediated by feelings of gratitude and sacrifice and moderated by effort obtaining the discount and format of the discount. Research limitations/implications Theoretically, this research advances the understanding of consumers’ interpretations of price promotions. All studies are conducted in an online context. Practical implications This research informs retailers and charity institutions on the best timing for soliciting checkout donations and indicates specific tactics to enhance consumers’ donations. Originality/value This is the first study linking price discounts to the growing phenomenon of checkout donations. The research is different from cause marketing where the donation is included in the price of a specific product. The work also differs from studies examining the spillover effect where additional purchases benefit the consumers instead of a cause.

Effect Magnitude

A primary psychometric concern with laboratory-based inhibition tasks has been their reliability. However, a reliable measure may not be necessary or sufficient for reliably detecting effects (statistical power). The current study used a bootstrap sampling approach to systematically examine how the number of participants, the number of trials, the magnitude of an effect, and study design (between- vs. within-subject) jointly contribute to power in five commonly used inhibition tasks. The results demonstrate the shortcomings of relying solely on measurement reliability when determining the number of trials to use in an inhibition task: high internal reliability can be accompanied with low power and low reliability can be accompanied with high power. For instance, adding additional trials once sufficient reliability has been reached can result in large gains in power. The dissociation between reliability and power was particularly apparent in between-subject designs where the number of participants contributed greatly to power but little to reliability, and where the number of trials contributed greatly to reliability but only modestly (depending on the task) to power. For between-subject designs, the probability of detecting small-to-medium-sized effects with 150 participants (total) was generally less than 55%. However, effect size was positively associated with number of trials. Thus, researchers have some control over effect size and this needs to be considered when conducting power analyses using analytic methods that take such effect sizes as an argument. Results are discussed in the context of recent claims regarding the role of inhibition tasks in experimental and individual difference designs.

The Impact

Travellers have high standards and regard restaurants as important travel attributes. In the tourism and hospitality industry, the use of developed tools (e.g., smartphones and location-based tablets) has been popularised as a way for travellers to easily search for information and to book venues. Qualitative research using semi-structured interviews based on the face-to-face approach was adopted for this study to examine how consumers’ restaurant selection processes are performed with the utilisation of social media on smartphones. Then, thematic analysis was adopted. The findings of this research show that the adoption of social media on smartphones is positively related with consumers’ gratification. More specifically, when consumers regard that process, content and social gratification are satisfied, their intention to adopt social media is fulfilled. It is suggested by this study that consumers’ restaurant decision-making process needs to be understood, as each stage of the decision-making process is not independent; all the stages of the restaurant selection process are organically connected and influence one another.

Aluminium is a metal of high economic importance for the European Union (EU), presenting unique properties (e.g., light weight and high corrosion resistance) and with applications in important sectors (e.g., transportation, construction and packaging). It is also known for its high recyclability potential, but relevant losses occur in its life cycle, compromising the amount of aluminium available for secondary production. A novel methodology that allows the identification of these losses and their impact on the aluminium flows in society is the MaTrace model. The objective of this article is to perform a dMFA of the secondary production of aluminium in the EU technosphere using the modified version of MaTrace, in order to estimate flows of the metal embedded in 12 product categories. Twelve scenarios were built in order to assess the impact of changes in policies, demand and technology. The flows were forecasted for a period of 25 years, starting in 2018. The results of the baseline scenario show that after 25 years, 24% of the initial material remains in use, 4% is hoarded by users, 10% has been exported and 61% has been physically lost. The main contributor to the losses is the non-selective collection of end-of-life products. The results of the different scenarios show that by increasing the collection-to-recycling rates of the 12 product categories, the aluminium that stays in use increase up to 32.8%, reaffirming that one way to keep the material in use is to improve the collection-to-recycling schemes in the EU.

Abstract Background Natural or quasi experiments are appealing for public health research because they enable the evaluation of events or interventions that are difficult or impossible to manipulate experimentally, such as many policy and health system reforms. However, there remains ambiguity in the literature about their definition and how they differ from randomized controlled experiments and from other observational designs. We conceptualise natural experiments in the context of public health evaluations and align the study design to the Target Trial Framework. Methods A literature search was conducted, and key methodological papers were used to develop this work. Peer-reviewed papers were supplemented by grey literature. Results Natural experiment studies (NES) combine features of experiments and non-experiments. They differ from planned experiments, such as randomized controlled trials, in that exposure allocation is not controlled by researchers. They differ from other observational designs in that they evaluate the impact of events or process that leads to differences in exposure. As a result they are, in theory, less susceptible to bias than other observational study designs. Importantly, causal inference relies heavily on the assumption that exposure allocation can be considered ‘as-if randomized’. The target trial framework provides a systematic basis for evaluating this assumption and the other design elements that underpin the causal claims that can be made from NES. Conclusions NES should be considered a type of study design rather than a set of tools for analyses of non-randomized interventions. Alignment of NES to the Target Trial framework will clarify the strength of evidence underpinning claims about the effectiveness of public health interventions.
