The purpose of this paper is to develop an original model and a solution procedure for solving jointly three main strategic fleet management problems (fleet composition, replacement and make-or-buy), taking into account interdependencies between them.

The three main strategic fleet management problems were analyzed in detail to identify interdependencies between them, mathematically modeled in terms of integer nonlinear programing (INLP) and solved using evolutionary based method of a solver compatible with a spreadsheet.

There are no optimization methods combining the analyzed problems, but it is possible to mathematically model them jointly and solve together using a solver compatible with a spreadsheet obtaining a solution/fleet management strategy answering the questions: Keep currently exploited vehicles in a fleet or remove them? If keep, how often to replace them? If remove then when? How many perspective/new vehicles, of what types, brand new or used ones and when should be put into a fleet? The relatively large scale instance of problem (50 vehicles) was solved based on a real-life data. The obtained results occurred to be better/cheaper by 10% than the two reference solutions – random and do-nothing ones.

The methodology of developing optimal fleet management strategy by solving jointly three main strategic fleet management problems is proposed allowing for the reduction of the fleet exploitation costs by adjusting fleet size, types of exploited vehicles and their exploitation periods.

The concept of trust suffers from conceptual confusion. The current perspectives on trust within the B2B marketing domain could be visualised as a big box of which the borders are defined by the disciplines marketing, economics, psychology and sociology. The purpose of this paper is to enlarge the box by introducing neuroscientific insights on trust to the B2B marketing domain.

By a literature study on neuroscientific insights on trust, this paper examines how neuroscience can help to solve existing problems within trust research and how it can address problems that otherwise might not be considered.

The neural coordinates of trust not only show that trust entails cognitive and affective elements, but also that these elements are so intertwined that they cannot be completely separated. What can and should be separated are the concepts of trust and distrust: the neural coordinates of trust are clearly different from the neural coordinates of distrust. Furthermore, there are personal differences in the ease of trusting others, which are not only caused by previous experiences but also by differences in resting patterns of frontal electroencephalographic asymmetry and by differences in hormonal state.

Specifically, the neural difference between trust and distrust might shape the future research agenda for trust research within industrial marketing. It is likely that the process of distrust goes quick, whereas trust comes more slow. This is reflected in the dual processing theory, which is seen as a paradigm shift in the psychology of reasoning.

New perspectives and directions for trust research are presented. The distinction between trust and distrust is connected to approach- and avoidance-motivated behaviour, which is highly relevant for deepening the studies on trust within industrial marketing.

This study investigates the presence of a productivity–quality trade-off in judicial decisions from an organisational standpoint, focusing on the courts as bureaucracies. Applied to the Italian context and focusing on criminal courts, the main question addressed is whether or not increasing productivity diminishes decision quality.

Directional distance function (DDF) models were utilised to assess productivity. Two-sample t-tests are then used to compare the quality of efficient and inefficient units in first instance and appeal, with the aim to determine whether a productivity–quality trade-off exists.

The study’s approach yields results that differ from previous studies. (1) The Italian judicial system is found less efficient. (2) The efficiency of the courts of first instance is relatively uniform. In contrast, there is a difference in efficiency between northern and southern courts of appeal, with northern courts on average being more efficient. (3) The analysis reveals a statistically significant productivity–quality trade-off when the courts of appeal are considered.

New evidence of a judicial system is presented, suggesting reforms regarding “reasonable time” as the optimal balance between quality and productivity.

The organisational framework leads to evaluating the efficiency of the courts by considering the various types of proceedings based on the gravity/complexity of the cases. In light of the pyramidal structure of the justice system, the quality is then defined in terms of hierarchical control expressed as review rate.

This paper aims to provide an overall review and assessment of the virtues and flaws of decentralized self-regulated markets, discussing in particular the extent to which deceiving attitudes by some market participants might be potentially diluted and contradicted.

To approach deception and morality in markets, the paper follows two paths. First, the relevant recent literature on the theme is reviewed, examined and debated, and second, one constructs a simulation model equipped with the required elements to discuss the immediate and long-term impacts of deceiving behaviour over market outcomes.

The discussion and the model allow for highlighting the main drivers of the purchasing decisions of consumers and for evaluating how they react to manipulating behaviour by firms in the market. Agents pursuing short-run gains through unfair market practices are likely to be punished as fooled agents spread the word about the malpractices they were allegedly subject to.

Markets are complex entities, where large numbers of individual agents typically establish local and direct contact with one another. These agents differ in many respects and interact in unpredictable ways. Assembling a concise model capable of addressing such complexity is a difficult task. The framework proposed in this paper points in the intended direction.

The debate in this paper contributes to a stronger perception on the mechanisms that attribute robustness and vitality to markets.

This case study explores trust at work, described by young professionals in the early stages of their careers. In this article, trust is approached as the study participants' experiences of interpersonal trust. More specifically, it refers to relationships between colleagues, among individuals or at group level (Ma et al., 2019). Supervisors or managers did not take part in this study. The research question was “What do young professionals tell about trust and its importance at work?”

The empirical study consists of qualitative data, focus group (5) interviews (n = 20) of young professionals who are in the early stages of their careers (1–3 years after graduation). The study is contextualized in Finland, in Helsinki metropolitan area, in three social and healthcare workplaces and two information technology (IT) organizations. Both public and private sectors are represented. The data were analysed by theory-based content analysis.

According to the study results, descriptions of trust and its importance at work can be placed in three main categories. First, trust is an important element in improving young professionals' adaptation into the working community. Second, trust strengthens young professionals' professionalism and professional development at work. Third, trust at work highlights ethical issues and their significance in workplace relationships. Practical implications and limitations are also discussed.

Due to the nature of this study, the research results should be viewed critically. The results can be seen as one suggestion to structure and increase understanding of trust in working life, from the perspective of young professionals in the early stages of their careers. As all research, the studies included in this review had several limitations that need to be taken into account. First, one of them is the size of the data, also in this study. Second, although literature has been searched carefully, there is always a chance of better literature existing for discussion on trust at work from young professionals' points of view, even though there is not a lot available on this specific topic. Nonetheless, literature of this study includes the most relevant classics of trust research. Third, the method has its own limits because it is based on focus group interviews, not interviews of individuals. On the other hand, it offered time for the team to reflect on trust in their own team. Still, this study offers one option for discussion of trust in work relationships. Additionally, it was noteworthy that the subjects were at the beginning of their careers, joining a new working community. They were in the early stages of building a professional identity, seeking confirmation of their skills and position in the working community. Thus, we recognize that this may have contributed to the collection of research data, which was a focus group interview. Few participants in the interview wanted to strongly point out the factors related to distrust, even if they had appeared at work. The authors recognize that exploring trust requires trust and acknowledge it. Data have been collected before the COVID-19 pandemic (see, e.g. van Zoonen et al., 2021).

This study implies that trust at work should focus on discussing young professionals' thoughts, expectations, feelings and experiences of trust at work as part of transitioning from graduation into working life or in early stages of their careers. Trust should not only be discussed in dyadic discussions between young professionals and supervisors but also as part of team discussions. The authors’ suggestion is that trust should be in the core of team discussions, not just as part of teams' social and emotional dimensions of their functionality and capacity. Courage and skills to take part in such discussions is needed from all parties. Especially leaders have to have the ability to create a trusting environment to talk about trust. In particular, the importance of peers in trust and their importance at work should be taken into account. By understanding young professionals’ point of view, we can prevent job changes or dissatisfaction at work too. The purpose of this study was to contribute to this line of research on trust at work. The trust resource contributes to and promotes the realization of participation in working life.

The trust resource contributes to and promotes the realization of participation in working life. Leaders and coworkers can learn about trust as a phenomenon, while developing more emotionally sustainable working environments for young professionals. Trust should be seen as a skill or competence to improve various positive functional dimensions at work.

The results demonstrate that it is crucial to ensure emotional sustainability at work, and a positive feeling of belonging at work supports young professionals by developing a trusting work environment. It strengthens their engagement in a new work.

The aim of this paper is to explore whether the use of an active learning methodology implemented through a mobile phone can help future teachers to develop more effective reading promotion activities than those based on traditional learning methodologies.

A study was conducted based on the comparison of perceptions of two groups of teacher training students. The experimental group was trained in an active methodology to promote reading on mobile phones, whilst the control group was trained in a classical methodology also using the same devices. Variables were observed using a self-administered questionnaire, and the scores obtained were analysed from their descriptive statistics of the comparison of means of Kruskal–Wallis H test.

The results showed that students perceived significant improvements associated with active learning methodology. The variables with the most remarkable results were those related to better use of the class, participation and satisfaction. However, the ubiquitous variable obtained the fewest differences, maybe because both learning methodologies were applied using mobile devices.

The conclusions of this study clearly suggest that combining active learning methodologies and the use of mobile phones to promote reading could lead to better results than applying traditional learning methodologies. The value of this study paves the way for future research to move forward in the discovery of effective teaching strategies based on active methods and mobile devices.

During the planting process, agricultural products produce large amounts of greenhouse gas (GHG) emissions. This has placed tremendous pressure on sustainable global development. Many countries and regions in the world have adopted intensive subsistence cultivation methods when planting maize; however, limited studies exist on these methods. The main purpose of this research is to show the impact of climate change on maize yields and carbon footprint (CF) in South Korea over 10 years, find the proper operating method and promote the advanced combination of inputs for the sustainable development of maize farmers.

This study used survey data from the South Korea Rural Development Administration of 2010, 2014 and 2019 to estimate the CF of maize planting under intensive subsistence cultivation. Life-cycle assessment was used to determine the CF. Farmers were grouped according to significant differences in yield and GHG emissions. Linear regression was used to measure the dependence of the main contributors on the CF production and carbon efficiency.

In South Korean maize planting, N in chemical fertiliser was the most significant contributor to the CF and organic fertiliser was the most significant input. The use of chemical and organic fertilisers significantly affects the production of the CF and carbon efficiency. Households in the high-yield and low-GHG emission groups are more sustainable because they generate the least GHG when producing and earning through maize cultivation. Globally, maize production in South Korea has a relatively low CF and maize production produces fewer GHG.

This study provides information for policymakers to determine key operational options for reducing GHG emissions using intensive subsistence cultivation of maize production in South Korea and other countries.

Vendors’ social cues – physical or behavioural hints – have an impact on the professional buyer. However, little is known about that impact. The purpose of this paper is to place knowledge about the impact of social cues that other disciplines acquired in the context of business-to-business (B2B) marketing to contribute constructively to the research agenda.

By integrating findings on the processing of social cues and the behavioural response from the disciplines of neuroscience, biology and psychology (specifically the behavioural inhibition system [BIS]/behavioural activation system [BAS]-theory), this paper aims to provide an interdisciplinary perspective on the automatic evaluation of vendors by professional buyers.

Social cues are likely to be of substantial value in the (first) encounter between buyer and seller. Positively evaluated social cues create an approach-motivated behavioural intention, whereas negatively evaluated ones create avoidance. This process is probably predominantly mediated by trust and moderated by personality and contextual factors.

This paper stimulates research about the impact of social cues in a B2B context. While such knowledge would add practical value, this paper also explores possibilities for managers to use neuroscientific techniques to assess and train sales agents.

The impact of social cues is hardly covered in the B2B marketing literature, but they have an important impact on B2B decision-making. The conceptual framework combines the BIS/BAS theory (approach/avoidance) with the SOR-model (stimulus-organism-response), which is unique to the B2B marketing field.

The purpose of this paper is to examine the career shocks of Red Cross (RC) of Serbia staff and volunteers providing aid during the 2016 migrants’ influx. Specifically, the authors explore what the volatile environment in which RC staff and volunteers work can teach us about career shocks, and what makes a career shock for people whose everyday work entails stressful events.

This study examined a number of anecdotes that reflect the career shock construct to a greater or lesser extent. These anecdotes were developed by RC staff and volunteers as part of a communications training storytelling exercise.

The authors analyzed these events from the perspective of recent developments in career shocks research and examined whether the anecdotes contained elements that would enable us to differentiate between career shocks and stressors. Those anecdotes found to be the most prototypical of career shocks, as opposed to stressors, were found to instigate in-depth reflection about the career, were identity related, and had a tangible career impact. Shocking events in the eyes of RC people entailed work demands that go beyond expectations, excessive media scrutiny, and conflicting values. The authors discuss how organizational values, fostering person–organization fit, providing organizational and collegial support, and deploying “weathered” staff, could comprise the “vaccine” that makes the organization immune to career shocks.

By taking a data before theory approach to the study of career shocks, this paper provides a novel perspective on the lived experiences of RC people, and how such experiences may be classified into career shocks or stressors.
