Abstract
Purpose
This paper aims to simulate a punch shear test of partly consolidated ice ridge keel by using a three-dimensional discrete element method. The authors model the contact forces between discrete ice blocks with Hertz–Mindlin contact model. For freeze bonds between the ice blocks, the authors apply classical linear cohesion model with few modifications. Based on punch shear test simulations, the authors are able to determine the main characteristics of an ice ridge from the material parameters of the ice and freeze bonds.
Design/methodology/approach
The authors introduced a discrete model for ice that can be used for modelling of ice ridges. The authors started with short introduction to current status with ice ridge modelling. Then they introduced the model, which comprises Hertz–Mindlin contact model and freeze bond model with linear cohesion and softening. Finally, the authors presented the numerical results obtained using EDEM is commercial Discrete Element Modeling software (EDEM) and analysed the results.
Findings
The Hertz–Mindlin model with cohesive freeze bonds and linear softening is a reasonable model for ice rubble. It is trivial that the ice blocks within the ice ridge are not spherical particles, but according to results, the representation of ice blocks as spheres gave promising results. The simulation results provide information on how the properties of freeze bond affect the results of punch shear test. Thus, the simulation results can be used to approximate the freeze bonds properties within an ice ridge when experimental data are available.
Research limitations/implications
As the exact properties of ice rubble are unknown, more research is required both in experimental and theoretical fields of ice rubble mechanics.
Originality/value
Based on this numerical study, the authors are able to determine the main characteristics of an ice ridge from material parameters of ice and freeze bonds. Furthermore, the authors conclude that the model creates a promising basis for further development in other applications within ice mechanics.

Abstract
Purpose
In the COVID-19 pandemic, consumers increasingly opt for, or are forced to, use home delivery services. The authors study retailers' decisions regarding “delivery mode”, which is about outsourcing (vs. insourcing) the delivery service to a traditional delivery company or an unbranded carrier and its effects on consumers' perceived overall quality, perceived hygienic quality, and subsequently, willingness to stay with the firm beyond the pandemic.
Design/methodology/approach
A pre-test, an experiment and a post-test were conducted with participants from the UK (Total N = 380).
Findings
The results of this study show that (1) in a pandemic, perceived hygienic quality overshadows perceived service quality as a key determinant of consumers' choices, and (2) while consumers have a relatively negative view of the hygienic level of unbranded carriers, they do not differentiate between traditional delivery carriers and retailer-branded carriers. Thus, they are equally interested in using the services of the latter ones.
Originality/value
This study shows that during a health crisis, consumers change their hierarchy of motivations to reflect the new protection motivations. The authors usher perceived hygienic quality as a variable that should be seriously considered as both a tactical and a strategic variable affecting the attractiveness of alternative home delivery methods and consumers' intentions to continue using them after the pandemic.

Abstract
Purpose
While most marketing research on organic products refers to the premium price levels of organic products, little research exists on consumers’ behavioural responses to price promotions or discounts of organic products. The present study aims to fill this research gap.
Design/methodology/approach
To develop alternative hypotheses about consumers’ behavioural responses to price promotions of organic fast-moving consumer good (FMCG) products, the authors used the researcher-introspection method in a pre-study. To test the hypotheses developed based on the pre-study, the authors conducted a field experiment on online advertising of an FMCG sold in drugstores. In the field experiment, the authors exposed consumers to an online ad featuring either a price promotion (−20%) or the regular price of the product. The ads also varied in terms of whether they contained explicit organic claims or not, and whether they included implicit organic cues or not.
Findings
The price promotion increased the clickthrough rate of the ad both when combined with an explicit organic claim and when combined with the implicit cue of green product pack. The results suggest that consumers do not have significant suspicions about price promotions of organic products, but rather presume that the price promotion of an organic FMCG product is a periodical promotional action, similar to the price promotions for conventional, non-organic products. Also, consumers seem to assume that the regular prices of organic FMCG products are so high that the retailer/manufacturer can well afford periodic price discounts.
Research limitations/implications
The present research shifts the focus of organic marketing research from the premium price levels to the effectiveness of price promotions and discounts. Further, the present results contrast with certain earlier studies that have questioned the effectiveness of price promotions for organic products.
Practical implications
The results have different implications for marketing managers of brands not yet providing organic product versions in the market, of brands producing non-organic products, which cannot easily be rendered organic, and of brands offering organic products in the market.
Originality/value
This is, to the best of the authors’ knowledge, the first empirical study and field experiment on price promotions of organic products, including explicit organic claims.

Abstract
Purpose
Even as multi-story apartment building development proposals in existing neighbourhoods represent a substantial component of policy debate at local planning boards, there is limited evidence for the impact of such residential developments on surrounding apartment values. This paper aims to address the void in knowledge, and the impact of multi-story apartment building developments on apartment values in residential high-rise areas located outside city and district centres is investigated in Helsinki Metropolitan Area, Finland.
Design/methodology/approach
Whether a multi-story apartment building development is followed by an increase in housing values depends on both positive and negative externalities. To specify valuation effects of proximate development projects, advanced research design combining matched sample methodology and hedonic-based difference-in-difference approach is used.
Findings
It appears from the analysis that completion of a single multi-story apartment building has an immediate positive impact on apartment values within 300 metre radius, while there is no statistically significant impact on price trend.
Research limitations/implications
This paper studies apartment values only in Helsinki Metropolitan Area, Finland, and it is important to notice that local regulations and market conditions may have a notable impact on the outcomes.
Originality/value
This study is the first of its kind to provide with statistically significant evidence for positive impacts from multi-story apartment building development in Finnish residential high-rise areas and may have a crucial role in helping to dispel prejudices related to such developments.

This research examines what motivates professional truck drivers to engage in eco-driving by linking their self-reports with objective driving scores.
Abstract
Purpose
This research examines what motivates professional truck drivers to engage in eco-driving by linking their self-reports with objective driving scores.
Design/methodology/approach
Theory of Planned Behavior (TPB) is illustrated in an embedded, single-case study of a Finnish carrier with 17 of its truck drivers. Data are obtained through in-depth interviews with drivers, their fuel-efficiency scores generated by fleet telematics and a focus group session with the management.
Findings
Discrepancies between drivers’ intentions and eco-driving behaviors are illustrated in a two-by-two matrix that classifies drivers into four categories: ideal eco-drivers, wildcards, wannabes and non-eco-drivers. Attitudes, subjective norms and perceived behavioral control are examined for drivers within each category, revealing that drivers’ perceptions did not always align with the reality of their driving.
Research limitations/implications
This study strengthens the utility of TPB through data triangulation while also revealing the theory’s inherent limitations in elucidating the underlying causes of its three antecedents and their impact on the variance in driving behaviors.
Practical implications
Managerial insights are offered to fleet managers and eco-driving solution providers to stipulate the right conditions for drivers to enhance fuel-efficiency outcomes of transport fleets.
Originality/value
This is one of the first studies to give a voice to professional truck drivers about their daily eco-driving practice.

Abstract
Purpose
This study aims to examine the interplay between focal and background goals in consumer financial decision-making and identify conditions that lead individuals to trade-off financial returns for background goals.
Design/methodology/approach
The current research reviews the relevant literature on consumer financial decision-making and goal systems theory to develop a set of hypotheses that is tested using three experiments.
Findings
The experiments show that individuals who have been subtly primed with self-expressive background goals, or experienced progress toward the focal goal of financial returns, accept lower financial returns for the opportunity to invest in stocks that allow for increased self-expression. Further, while subtly primed background goals exert a non-normative influence on investment decisions, explicit cues about an investment’s background goal-instrumentality create a backlash effect, and decrease individuals’ willingness to trade-off financial returns.
Research limitations/implications
Future research could confirm the robustness of the findings of the present research by using different priming tasks and alternative ways of making the background goal explicit to individuals.
Practical implications
To achieve greater attraction among individual investors, it helps to frame a financial product or stock in communications materials in a way that sends subtle signals with which investors can identify. Such signals could include stressing the product/company’s home country (addressing individuals’ patriotism) or a particular product domain (addressing individual investors’ desire for interesting/exciting current/future products).
Originality/value
While previous research suggests that investment choices may be influenced by self-expressive motivations, to date, it remains unclear whether and when individual investors are actually willing to trade-off the focal goal of maximizing financial returns for the opportunity to satisfy alternative background goals.

Abstract
In this chapter, I utilize insights from symbolic interaction to analyze the identity work processes of larp subculture participants to construct and perform their in-game identities. I extend the research on larp subcultures in two ways. First, I place larping within the larger context of leisure subcultures and society by arguing that larping is representative of changes in leisure and subcultures in postmodern society. Second, I draw upon ethnographic data collected among the New England Role-playing Organization (NERO) to analyze larpers character identity performances. RPG and Larp researchers have developed several theories about the relationship between larp participants and their character performances. While these concepts provide a helpful framework for understanding the participant-character relationship, they undertheorize the in-game constructed performance of identity. Using symbolic interaction theory, I analyze the identity work processes larpers use to construct and perform their larp identities extending our understanding of the similarities between everyday identity and larpers' character identity performances.

The purpose of this paper is to investigate positive mental health (PMH) and factors related to it among those living alone in the sparsely populated area of the Lapland region.
Abstract
Purpose
The purpose of this paper is to investigate positive mental health (PMH) and factors related to it among those living alone in the sparsely populated area of the Lapland region.
Design/methodology/approach
The study utilises data from the Mental Health Survey of the Lapland region in Finland, covering 12 municipalities. The scores of short Warwick–Edinburgh Mental Well-Being Scale (sWEMWBS) were categorised into three levels of PMH. Logistic regression models were used to separately estimate the odds ratios for the high level of PMH compared with the moderate level of PMH and the low level of PMH compared with the moderate level.
Findings
Social support seemed to be very strongly associated with both low and high levels of PMH among people living alone. Participating in activities provided by organisations or societies decreased the odds of having low PMH. Among men, young age predicted low PMH.
Originality/value
The number of people living alone in Finland and other parts of Europe is increasing, yet there are few studies focusing on their positive mental health (PMH). Using scales such as sWEMWBS adds to the authors’ knowledge about the positive mental well-being of those living alone, especially in rural areas, thus making it possible to utilise mental health promotion interventions effectively and accordingly.

Abstract
Purpose
In the age of digital media, customers have access to vast digital information sources, within and outside a company's direct control. Yet managers lack a metric to capture customers' cross-media exposure and its ramifications for individual customer journeys. To solve this issue, this article introduces media entropy as a new metric for assessing cross-media exposure on the individual customer level and illustrates its effect on consumers' purchase decisions.
Design/methodology/approach
Building on information and signalling theory, this study proposes the entropy of company-controlled and peer-driven media sources as a measure of cross-media exposure. A probit model analyses individual-level customer journey data across more than 25,000 digital and traditional media touchpoints.
Findings
Cross-media exposure, measured as the entropy of information sources in a customer journey, drives purchase decisions. The positive effect is particularly pronounced for (1) digital (online) versus traditional (offline) media environments, (2) customers who currently do not own the brand and (3) brands that customers perceive as weak.
Practical implications
The proposed metric of cross-media exposure can help managers understand customers' information structures in pre-purchase phases. Assessing the consequences of customers' cross-media exposure is especially relevant for service companies that seek to support customers' information search efforts. Marketing agencies, consultancies and platform providers also need actionable customer journey metrics, particularly in early stages of the journey.
Originality/value
Service managers and marketers can integrate the media entropy metric into their marketing dashboards and use it to steer their investments in different media types. Researchers can include the metric in empirical models to explore customers' omni-channel journeys.

Abstract
Purpose
The purpose of this paper is to examine the links between individual investors' subjective evaluations of certain companies' products and brands, on one hand, and their willingness and decisions to invest in those companies' stocks, on the other. The authors aim to challenge the traditional assumption that individuals would make stock investment decisions purely on the basis of expected financial returns and risks.
Design/methodology/approach
Survey data were collected from 293 individuals who invest in the stock market of a European country and analyzed with PLS path modeling.
Findings
In the clear majority of the consumers' stock investment decisions that were analyzed, the consumers exhibited some willingness to invest in a chosen stock beyond its expected financial returns/risk. Two variables are found to elicit willingness to invest in a company's stock beyond its financial returns: the personal relevance that the individual attaches to domains (activities or areas of interest; ideas or ideals) supported or represented by the company's products; and the individual's affective evaluation of the company's product brand.
Research limitations/implications
Replicating the study with different companies from different industries and with consumers from different countries will be important. Overcoming a potential retrospection bias in the reported study is also a task for further research.
Practical implications
The findings provide insights that can serve segmentation, targeting, and positioning when it comes to marketing a company in the stock market so as to attract investors.
Originality/value
The paper provides new evidence on the influence of product and brand evaluations in consumers' stock investment decisions – suggesting that positive product evaluations elicit extra willingness to invest in a company's stock, over and beyond its financial returns.
