Abstract

Purpose

Cannabis use continues to increase worldwide, and a number of nation states are changing their cannabis policies. Policy changes require research into key populations, namely, people who use cannabis. This study aims to examine sociodemographic differences of young Finns who reported using cannabis mainly for self-medication versus mainly recreationally, as well as their reported effects of cannabis use.

Design/methodology/approach

The data come from an anonymous online survey (N = 247, 70.0% males, 25.9% females, 4.1% other) that was analysed using multiple logistic regression. The authors focused on whether various demographic indicators differed between those who reportedly used cannabis mainly for recreational purposes and mainly for self-medicinal purposes. The authors also qualitatively examined the respondents’ experienced effects of cannabis, both desired and undesired.

Findings

Being older and female, living in a smaller city and earlier age of initiation of cannabis use were statistically significant in predicting the medicinal use of cannabis. The majority of recreational effects were related to themes such as relaxation and pleasure, but many participants also reported desired medical effects. Similarly, many participants reported several undesired effects.

Research limitations/implications

Understanding especially young people’s motivations to use cannabis, which include using it for various medical effects, can improve the design of harm reduction and treatment programmes as well as enhance the well-being of people who use cannabis.

Originality/value

This study gives a nuanced account of sociodemographic factors and motivations of young people who use cannabis in Finland as well as the reported effects it has on them, which complements data from national drug surveys.

Abstract

Purpose

Football is significant in the global economic context. However, the same significance is not identified in the value added to the chain, as the elements that make it up act in a disintegrated and independent manner with undesired effects. Consequently, it is necessary to structure the undesired effects to seek the basic causes that sustain this problematic situation. Thus, this paper aims to use a CRT to structure the undesired effects and basic causes that limit the positive economic impacts of the south Brazilian football value chain.

Design/methodology/approach

A semi-structured questionnaire was applied with questions about the existing constraints. Based on the answers in the interviews, the current reality tree was elaborated, premised on identifying the basic causes that sustain the undesirable effects detected.

Findings

Among the main results, it was identified that management problems of the traditional leaders of football clubs and federations are considered the main reason why south of Brazil football cannot fully exploit its economic potential.

Originality/value

It is evidenced that the paper shows the undesired effect that has the most impact on the development of this chain, and it is important to propose improvements to its root causes, aiming at greater efficacy of the resulting actions.

Abstract

Purpose

Although windy weather conditions have a significant effect on the flight safety and stability of any aircraft, the fact that quadrotors are lighter than other aircraft makes them more sensitive to the wind. This study aims to examine the extent to which quadrotors and their sensors, which are used in many fields and whose use is expected to increase significantly in the future, are affected by wind.

Design/methodology/approach

Flight experiments were carried out on different routes assigned by using Pixhawk Holybro 4 and Radiolink flight controllers. In these flight experiments, quadrotors were exposed to winds at different speeds and directions.

Findings

In the flight experiments, the deviation amounts in the quadrotor’s route at which wind speed was determined, and it was seen that these deviations were very serious and affected the safe flight at high wind speeds. According to the sensor information obtained from both different quadrotors’ flight experiments at different wind speeds, it was determined that the wind decreased the sensors’ accuracy.

Practical implications

It is foreseen that the data obtained in this study will be a source to be used in the design of quadrotors to be used in public areas in the future and to take the wind into account for safe flight.

Originality/value

In this study, numerous flight tests were carried out experimentally at various speeds from low speeds to high speeds on different routes using different flight controllers. The deviation data on the obtained routes and the effect of the wind on the sensors are experienced in real atmospheric conditions.

Abstract

Purpose

Hydrothermal waves represent the preferred mode of instability of the so-called Marangoni flow for a wide range of liquids and conditions. The related features in classical rectangular containers have attracted much attention over recent years owing to the relevance of these oscillatory modes to several techniques used for the production of single crystals of semiconductor or oxide materials. Control or a proper knowledge of convective instabilities in these systems is an essential topic from a material/product properties saving standpoint. The purpose of this study is to improve our understanding of these phenomena in less ordinary circumstances.

Design/methodology/approach

This short paper reports on a numerical model developed to inquire specifically about the role played by sudden changes in the available cross-section of the shallow cavity hosting the liquid. Although accounting for the spanwise dimension would be necessary to derive quantitative results, the approach is based on the assumption of two-dimensional flow, which, for high-Pr fluids, is believed to retain the essence of the involved physical processes.

Findings

Results are presented for the case of a fluid with Pr = 15 filling an open container with a single backward-facing or forward-facing step on the bottom wall or with an obstruction located in the centre. It is shown that the presence of steps in the considered geometry can lead to a variety of situations with significant changes in the local spectral content of the flow and even flow stabilization in certain circumstances. The role of thermal boundary conditions is assessed by considering separately adiabatic and conducting conditions for the bottom wall.

Originality/value

Although a plethora of studies have been appearing over recent years motivated, completely or in part, by a quest to identify new means to mitigate these instabilities and produce accordingly single crystals of higher quality for the industry, unfortunately, most of these research works were focusing on very simple geometries. In the present paper, the causality and interdependence among all the kinematic and thermal effects mentioned above is discussed.

Abstract

Purpose

This study systematically reviews the literature on psychological ownership theory since its inception 30 years ago. Psychological ownership describes why and how individuals inform their identities by taking ownership. The authors provide guidance and support to management scholars to access the field and make meaningful contributions to the literature.

Design/methodology/approach

A variety of bibliometric techniques for performance analyses and science mapping is implemented to examine quantitative bibliographic data of 178 studies on psychological ownership. The data are obtained from Web of Science. The VOSviewer science mapping framework is employed to perform the analyses.

Findings

Co-authorship, citation and keyword co-occurrence networks indicate the social structures, most influential authors, publications and journals, as well as topics of past research and avenues for future investigation in the field of psychological ownership. While the authors of the seminal studies Pierce et al. (2001, 2003) have shaped the field over the past decades, the future of psychological ownership research requires stronger collaborations across the globe to advance the field from the individual level to the group and organization level.

Originality/value

This study is the first to comprehensively analyze the management literature on psychological ownership from a historical perspective using a systematic approach, bibliometric procedures and quantitative data. Insightful guidance and avenues for future investigation are offered to move psychological ownership research forward.

Abstract

Purpose

The purpose of this paper is to identify strategic options and challenges that arise when an industrial firm moves from providing smart service toward providing a platform.

Design/methodology/approach

This conceptual study takes on a multidisciplinary research perspective that integrates concepts, theories and insights from service management and marketing, information systems and platform economics.

Findings

The paper outlines three platform types – smart data platform, smart product platform and matching platform – as strategic options for firms that wish to evolve from smart service providers to platform providers.

Research limitations/implications

Investigating smart service platforms calls for launching interdisciplinary research initiatives. Promising research avenues are outlined to span boundaries that separate different research disciplines today.

Practical implications

Managing a successful transition from providing smart service toward providing a platform requires making significant investments in IT, platform-related capabilities and skills, as well as implement new approaches toward relationship management and brand-building.

Originality/value

The findings described in this paper are valuable to researchers in multiple disciplines seeking to develop and to justify theory related to platforms in industrial scenarios.

Abstract

This case challenges students to apply financial reporting concepts pertaining, most notably, to liabilities and expenses in a specific corporate situation. In the context of an interesting, but noncomplex, technical accounting issue, students debate the best way for Adenosine Therapeutics to present its compensation arrangements in its financial statements. In addition, this case also prompts students to debate the best way for a growing company, with cash constraints, to provide incentive and maintain top employees.

Abstract

Purpose

This paper aims to investigate how marketing leakage to undesired audiences, a common phenomenon in today's globally connected world of consumers, impacts on the target audience, and how marketers can mitigate the negative effects of leaked marketing.

Design/methodology/approach

The authors conduct three studies in line with research on the third-person effect (TPE). The studies feature experimental designs with participants from neighbouring countries.

Findings

The first study finds that people in the intended target audience expect and overestimate a (negative) reaction in the undesired audience to marketing leakage, and this impacts negatively on their own reactions. The second study replicates and extends the findings, showing that explicit information that marketing has leaked to an undesired audience impacts negatively on both the attitudes and behaviors of the intended, target audience. The third study tests potential strategies to mitigate the negative effects of leaked marketing and finds that the most important thing is to inform the intended target audience that the undesired audience has accepted the marketer's actions.

Research limitations/implications

Extending the TPE to marketing, this is, to the authors' knowledge, a first investigation of the previously neglected phenomenon of marketing leakage and the impact of undesired audiences on marketing effectiveness. It hopes to stimulate further research on consequences of marketing leakage and enrich research on international advertising and crisis management.

Originality/value

This is, to the authors' knowledge, the first inquiry into how and why marketing leakage to undesired audiences impacts on the intended target audience, and how negative effects can be mitigated. The original use of a third-person approach in this setting helps explain marketing effectiveness and assess managerial strategies.

Abstract

Purpose

The purpose of this paper is to present a case of integration between the processes modeling by using the Value Stream Mapping (VSM) and the Thinking Process of the Theory of Constraints (TP-TOC) through the analysis of productive processes of an organization, indicating the complementary aspects between them and their benefits to the organization.

Design/methodology/approach

The paper uses a company of the Brazilian automotive industry as the administering site. The research began by identifying the organization's processes and choice of a family of products to model according to the VSM approach. The integrated view between the losses in the process (VSM) and the unwanted effects of the adding value process were analyzed by using the Current Reality Tree. After the analysis, different improvement procedures are proposed based on the lean principles. Finally, a work plan is presented based on the previous steps aiming to achieve the proposed future state.

Findings

The analysis of this case helps to understand and identify the causes of the current problems in the processes studied, providing an integrated view between the losses in the process and the prioritization of steps for the elimination of such losses. The approach in its initial administration was robust and the solution steps were promising. By integrating these approaches, it was possible to verify improvement opportunities by identifying the losses and the basic causes that sustain the unwanted effects in the processes at the same time.

Originality/value

The study proposes an approach that enables a systematic and systemic analysis of the processes at organizations through the combined use of process modeling through the VSM and TP-TOC. Simultaneously, the losses in the processes and the unwanted effects are identified. Thus, through the construction of an effect-cause-effect robust logic, both losses in particular and the unwanted effects in general can be prioritized in order to maximize the improvement efforts in the processes.

Abstract

Purpose

The purpose of this paper is to first define the “jet principle” of (e‐)learning as providing dynamically suitable framework conditions for enhanced learning procedures that combine views from multiple cultures of science. Second it applies this principle to the case of the “Global Studies” curriculum, a unique interdisciplinary curriculum at Graz University in Austria that is targeted to multicultural and developmental learning among students from diverse ethnic and disciplinary backgrounds.

Design/methodology/approach

Social and learning procedures are heuristically analysed based on ten years of interdisciplinary experience in interdisciplinary learning settings in a multicultural environment with critical approach to globalisation, while also diverse scientific disciplines are counted as “cultures of understanding”.

Findings

The outcomes of the analysis suggest that the negation‐oriented web‐supported five‐level learning suite “Surfing Global Change” (SGC) is capable of providing helpful framework conditions to multicultural learning that can suitably be applied in the “Global Studies” curriculum as well as in other similar international curricula.

Research limitations/implications

Quality criteria are subject to scientific cultures and hence differ from discipline to discipline; thus representing continuous challenge for suitable perception of actors and bystanders.

Practical implications

Complexities of cultural diversity are reflected also by complexities caused by origins in diverse scientific cultures. For constructing thorough and practically implementable consensus solutions, dialogic processes and peer review are best mediated through web‐based discussion, for which this paper provides examples. Discourse‐oriented features and amendments for curricula of “Global Studies” are presented.

Social implications

Networking among multicultural and interdisciplinary curricula with a critical stance towards globalisation is facilitated through suggestions in this paper.

Originality/value

By offering a new type of graphic notation for learning procedures, this paper facilitates new perspectives on the intrinsic dynamics of learning, adoption of new standpoints and acquiring a 360° view of the institutional landscape and interest patterns in complex multi‐stakeholder issues such as globalisation.
