This chapter outlines how the academic field in Germany, particularly universities as institutions of research and education, became a constitutive element in the process of digitalization. Institutions in higher education created long-lasting networks not only by scientific relations in the academic field but also by the establishment of business-oriented and application-oriented disciplines. This chapter focuses on the case of business information systems (BIS) and reconstructs the structural conditions under which BIS evolved from an initially marginal data-centric subfield of business administration into an independent discipline. This discipline has had a major influence on the transformation of work processes in recent decades and is an important player in the digital transformation in Germany. This chapter therefore also outlines the far-reaching implications of the paths taken, which are eventually not limited to the academic field but manifested in transformed work processes in almost all professional fields.

The authors propose a dairy bundle, integrating strategies to jointly maximise producer revenue and consumer utility according to the latter's preferences.

An algorithm based on a nested logit model identifies the bundle maximising producer revenue based on factors affecting consumer purchase behaviour. The data are drawn from a mall-intercept survey administered in Iran, with consumers stating a hypothetical choice among a comprehensive set of dairy products.

Demographic characteristics and marketing mix elements significantly affect consumers' preferences. An algorithm based on the estimated dissimilarity parameter determines the best bundle of dairy products, simultaneously obtaining the highest utility and the highest expected revenue.

Consumer preference and maximum producer or retail seller income are considered simultaneously. The bundling promotion strategy is widely used for food offerings and fresh foods and can be extended to other products.

This paper is determined to examine the role of body image and materialism in predicting the identity exploration of university students when conspicuous consumption is a mediator variable.

The study used a quantitative method. Data were collected from students of three federal universities in Nigeria. The sample size was 331. A self-report questionnaire was used to collect data and analysis was performed using the partial least squares structural equation modelling.

Findings reveal that materialism has a negative association in predicting the identity exploration of students. At the same time, there was a significant full and partial mediating effect of conspicuous consumption on the relationship between body image and materialism on identity exploration, respectively.

The study provides valuable information for parents in understanding how conspicuous consumption may influence their children’s identity formation. The findings can also be helpful for educators in the design of discussions and interventions for students on the social-psychological antecedents of conspicuous consumption and identity exploration. Government and regulatory agencies can use the study’s findings to shape student financial literacy and consumer protection policies.

This study makes both theoretical and methodological contributions to the existing literature. It provided concrete empirical evidence establishing a subtle connection between the symbolic self-completion theory and the identity status paradigm. It is also amongst the first single research conducted within the scope of these two theories in the Nigerian higher education context.

This study aims to assess the nature and scope of dog-based programmes in prisons, assessing critically the potential opportunities, benefits, challenges and risks of developing innovative dog-based programmes for older prisoners in England and Wales. This paper outlines the potential benefits and challenges of developing dog-based programmes for older prisoners and sets out next steps for future research and practice.

This study is based on a scoping review of published research literature on prison dog programmes (PDPs) in the USA, the UK and other countries, with particular reference to older people in prison, followed by semi-structured interviews with six members of an expert advisory group. The literature review and data from the qualitative interviews were analysed thematically.

There is a substantial body of published research literature which supports PDPs as having identifiable positive impacts for people and also dogs, and also published research which highlights the benefits to older people of dog ownership or participation in dog-based activities. However, much of this research is small-scale and qualitative, and it has been argued that there is a lack of a quantitative evidence base. This research concludes that findings from the literature review and the semi-structured interviews support further research and the creation of pilot projects to develop dog-based projects for older people in prison.

This study was small-scale, and the findings need to be approached with caution. The literature review searched a small number of databases and filtered out articles published in languages other than English, and the review of the grey literature focused on reports from the UK. The number of experts interviewed was small and there was no direct consultation with older people in prison nor with older people with recent personal lived experience of imprisonment and community resettlement. A more extensive future study would benefit from a more extensive literature review, a larger group of participants and the inclusion of service users, prison managers and government policymakers, subject to the appropriate ethical and security approvals. At the time the research took place, ongoing COVID-19 restrictions on prison research meant that research with current prisoners and prison managers would not have been approved by the HMPPS NRC.

This research provides a research-based justification for future dog projects for older prisoners, leading potentially to improved well-being for older people in prison.

This study brings together the published research literature on PDPs with the research literature on the needs and experiences of older people in prison for the first time, and identifies potential directions for future research.

This study aims to examine consumer perception during COVID-19 and identifies cruise industry marketing strategies to fill a gap in crisis management and product pricing literature.

This study developed and validated two-factor measurement scales (vaccine perception and protective behavior), which predicted cruise intents well. This study revealed how geo-regional factors affect consumer psychology through spatial analysis.

This study recommended pricing 7-day cruises at $1,464 (the most preferred length). The results also showed that future price hikes would not affect demand and that coastal marketing would help retain customers.

This study contributed to the business, hospitality and tourism literature by identifying two new and unique factors (vaccine perception and protective behaviors), which were found to affect consumers’ intention to travel by cruise significantly. The result provided a better understanding of cruise tourists’ pricing preferences and the methods utilized could easily be applied to other cruise markets or tourism entities.

Guilt appeals are increasingly being used in road safety campaigns, despite recent research that has raised doubts about their effectiveness and the potential for triggering defensive responses. Building on the extended parallel process model, this study aims to add to this growing body of research by evaluating whether combining a hope message with guilt appeals can solve this problem.

An online experiment with a 2 (Appeal type: Guilt vs Guilt+hope) × 2 (Language intensity: Low vs High) between-subjects design was conducted. A total of 399 participants recruited from Amazon’s Mechanical Turk were randomized to view one of the four advertisements discouraging texting while driving (TWD). Their affective responses, perceptions about the advertisements and intentions to not TWD were measured.

The results showed that compared to guilt-only appeals, guilt+hope appeals directly reduced defensive responses (i.e. perceived manipulative intent and anger) across varying levels of language intensity. In addition, guilt+hope appeals mitigated the negative impacts of manipulative intent on intended emotions and intentions to not TWD.

Findings of this study mark the first to support the idea that communicating hope within guilt appeals is a promising social marketing strategy to discourage TWD.

This paper aims to develop bilayer woven fabrics with different picking sequences with enhanced comfort without any change in the constituent materials.

Six bilayer woven fabrics were produced on Dobby loom with 3/1 twill weave using micro-polyester yarn. Three different picking sequences, i.e. single pick insertion (SPI), double pick insertion (DPI) and three pick insertion (3PI), were used in both face and back layers. The effect of picking sequence on air permeability (AP), volume porosity, thermal resistance and overall moisture management capability (OMMC) of the samples were analyzed.

The results showed that 3PI–3PI picking sequence gives the highest OMMC, AP and thermal resistance in bilayer woven fabrics and the least results exhibited by SPI–SPI picking sequence.

This research uses a bilayer woven system that develops channels and trapes the air causing higher thermal resistance; therefore, applicable for winter sports clothing rather than for summer wear. Developed bilayer woven fabrics can be used in winter sportswear to improve the comfort of the wearer and reduce fatigue during activity.

Authors have developed bilayer fabrics by changing the picking sequences, i.e. SPI, DPI and 3PI of weft yarns in both layers and compared their thermo-physiological comfort properties.

Using the integrated behavioural model (IBM) as a theoretical framework, this study aims to identify the determinants of saving behaviour among Malaysia's income-earning Generation Y (Gen Y) born in the years 1980–1995.

The study was conducted using a questionnaire survey targeting Gen Y respondents 500 sets of responses were obtained via convenience sampling method.

Analysis conducted using partial least squares structural equation modelling (PLS-SEM) revealed that there were positive relationships among instrumental attitude, injunctive norm, perceived control, self-efficacy and intention to save. Secondly, intention to save, financial literacy and time preference were found to positively influence saving behaviour.

Policymakers may find this study useful as the results reveal saving behaviour determinants of Gen Ys in Malaysia, and policies could then be formulated to improve Gen Y's saving behaviour.

This study contributes to the literature by applying the IBM to a study on saving behaviour.

The proposed model aims to consider the flying hours as a criterion to initiate maintenance operation. Based on this condition, aircraft must be checked before flying hours threshold is met. After receiving maintenance service, the model ignores previous flying hours and the aircraft can keep on flying until the threshold value is reached again. Moreover, the model considers aircraft age and efficiency to assign them to flights.

The aircraft maintenance routing problem (AMRP), as one of the most important problems in the aviation industry, determines the optimal route for each aircraft along with meeting maintenance requirements. This paper presents a bi-objective mixed-integer programming model for AMRP in which several criteria such as aircraft efficiency and ferrying flights are considered.

As the solution approaches, epsilon-constraint method and a non-dominated sorting genetic algorithm (NSGA-II), including a new initializing algorithm, are used. To verify the efficiency of NSGA-II, 31 test problems in different scales are solved using NSGA-II and GAMS. The results show that the optimality gap in NSGA-II is less than 0.06%. Finally, the model was solved based on real data of American Eagle Airlines extracted from Kaggle datasets.

The authors confirm that it is an original paper, has not been published elsewhere and is not currently under consideration of any other journal.

This paper aims to investigate the role of personal and affective factors in curbing unethical consumer behaviour (UCB). Specifically, this study scrutinizes how religiosity, consumer ethical beliefs (CEBs) and anticipated guilt influence UCB.

Using a survey-based approach, the author distributed offline and online questionnaires among students enrolled in a public university in Roorkee, India and analysed the data using structural equation modelling.

The results provide evidence that intrinsically religious individuals develop strong ethical beliefs, which can help them to refrain from unethical behaviour and adopt ethical conduct. Also, individuals prone to experiencing anticipated guilt show less inclination to commit unethical behaviour.

This research presents significant theoretical and practical implications to facilitate academic understanding and managerial decision-making in the context of consumer ethics.

This research is one of the few empirical studies in the Indian context that simultaneously examines the antecedents and consequences of CEB.
