Snacks at work are often of poor dietary quality. The main objective of the current study is to examine the effect of making vegetable snacks available at workplace meetings on consumption.

In three between-subjects field experiments conducted at a hospital and three ministries in the Netherlands, with meeting as the unit of condition assignment, attendees were exposed to an assortment of vegetables, varying in vegetable variety and presence of promotional leaflet in study 1 (N = 136 meetings), serving container in study 2 (N = 88 meetings) and additional presence of cookies in study 3 (N = 88 meetings). Consumption of vegetables and cookies was measured at meeting level to assess grams consumed per person.

Across the three studies, average consumption per meeting attendee was 74 g (SD = 43) for study 1; 78 g (SD = 43) for study 2 and 87 g (SD = 35) for study 3. In the first study, manipulation of perceived variety and information leaflets did not affect intake. In the second study, significantly more vegetables were eaten when they were offered in single sized portions (M = 97 g, SD = 45) versus in a shared multiple portions bowl (63 g, SD = 38) (p < 0.001). In the third study, no effect was found of the additional availability of cookies on vegetable consumption during the meeting.

The present studies show how availability of vegetables at unconventional occasions makes meeting attendants consume considerable portions of vegetables on average. As such, offering healthy snacks at the workplace may be a valuable part of workplace health promotion programs and positively change the “office cake culture”.

Vegetable intake is less than recommended in many countries worldwide. Many snacking occasions are at work, which makes office meetings a potential consumption occasion to encourage vegetable intake. Hence, the aim of this study is to examine whether free availability of vegetable snacks during meetings contributes to their consumption among meeting attendees and under what conditions consumption is optimal.

More and more governmental organizations are switching to information systems to enhance their operations and reduce cost but the development of these systems involves a lot of challenges. This paper aims to find out the challenges that project managers have to face during the development of such systems and the practices they can adopt to address these challenges.

To identify the challenges, data have been gathered across six key project management areas. The six targeted key areas are project integration management, project scope management, project time management, project cost management, project human resource management and project communications management. The authors have coordinated with 11 managerial-level IT professionals using semi-structured interviews and have gone through their communication archives.

Findings prove that practices such as focusing on cost reduction, informal congregations, trainings and frequent communication between vendor and client help in addressing the challenges. Furthermore, learning from management experiences of the managers can assist managers in similar role to create a pattern of success while working with governmental projects.

The authors peek into the development life cycle of a public sector project named as prison information management system. The project has encountered numerous challenges and has been accomplished in significantly delayed time than designated.

The circular economy (CE) has gained momentum in recent years as a new economic paradigm. While the CE sets a very defined vision for a sustainable future, it still operates in the present. As such, existing guidance on and research into the CE lack a necessary understanding of how to go from the present to the future. What if the future is different from what the CE expects? The CE cannot answer this question adequately and therefore is not capable of developing this understanding alone. To address this shortcoming, this paper proposes futures studies (FS) as a complementary discipline because it offers exactly what CE lacks: methods to explore alternative futures.

To understand the level of interdisciplinary research in the built environment between CE and FS, a systematic literature review is carried out using a bibliometric review and a snowballing technique. This manuscript reviews seminal literature in both fields and their theoretical background.

This paper demonstrates the lack of collaboration between CE and FS and highlights a systemic failure within CE, which is to consider the future as unknowable. It further provides an initial understanding of where the synergy sits, recommendations on where to start and introduces some of the FS chief methods that could be used by CE in the built environment.

The authors’ bibliometric review and snowballing approach might have missed out on some literature that still falls within the scope. Such limitations are due, on one hand, to the authors’ bibliometric review approach by selecting publications based on matching keywords. On the other hand, the snowballing approach is affected by the authors’ subjective judgements on which of the publications are worth to explore based mainly just on the title and abstract of the paper.

The inclusion of Futures Studies will allow a stronger focus on approaching possible futures to be integrated overtly into existing work, research and action within the CE community.

It is more reasonable to expect that by cooperatively creating and implementing constructed futures with FS methods and CE principles, a better future for the built environment be reached. This is why it is so relevant for humanity that these two communities start to interact as soon as possible and maintain and open and productive collaboration in transitioning towards a sustainable society.

To the authors’ knowledge, this research is the first of its kind by considering FS into the CE debate.

The purpose of this paper is to reconstruct the marketing history of medical marijuana cigarettes in the past three decades of Austria-Hungary.

This paper constructs an analytical narrative based on information scattered in historical periodicals.

Towards the end of Habsburg rule, two Ljubljana-based pharmacists, the Trnkóczy brothers, managed to establish themselves as monopolistic suppliers of pre-rolled medical marijuana cigarettes for the entire Austrian part of the dual monarchy. Garnering the support of the regional Carniolan Government, Julius von Trnkóczy successfully argued his wares were not affected by the prohibition passed against imported French medicinal cigarettes. This happened despite medical opposition, suggesting that Trnkóczys could only operate this business because of their elevated social status. In the past decade of the 19th century, Ubald von Trnkóczy took advantage of newly loosened regulation to obtain an official permit by the royal-imperial government in Vienna. This was followed, in late 1909, by an advertising campaign covering mass media throughout the empire. This was enabled, amongst others, by a cutting down on medicinal claims. Their declining price is further indication that the cigarettes were mass marketed, especially as their core ingredient, cannabis, underwent price inflation.

Because of its later illegality, the research subject was for a long time considered embarrassing, leading to an absence of retrievable documents. Missing archival sources are thus a major limitation, but one which can be overcome by the concurrent reading of historical periodicals – ranging from mass-market newspapers to specialist journals and legal texts. This paper has implications for 21st-century challenges in the marketing of newly legalized medical marijuana.

This paper discusses the marketing history of cannabis, a drug rarely discussed in historical literature outside its medical and regulatory context, and reconstructs previously forgotten case histories.

The paper aims to explore the relationship between gamification and design thinking approach to innovation in the context of the early stage of innovation process (ESoIP). Design thinking is conceptually appropriate to support innovative, complex and uncertain business environments. Still, its practices have demonstrated some difficulties in managing the ESoIP, such as lack of structure and clarity around goals. This paper argues that gamification can enhance and complement design thinking in the management of firms' ESoIP.

Given the need to achieve a deeper understanding of the linkages between gamification and design thinking, the paper follows an exploratory theory building approach for this complex reality of innovation. The case study research method was conducted in three firms (Trivalor, Novartis and Microsoft) that applied a gamification approach to the ESoIP.

The results demonstrate that gamification has the power to enhance and complement design thinking practices by getting tasks more organized and improving coordination and employees' engagement in the innovation process.

The paper provides critical managerial contributions on how firms can use gamification to improve design thinking approaches to ESoIP. Its consequences are also crucial to innovation, R&D, and product/service development managers interested in using gamification to support the ideation and concept development of new solutions complementing traditional design thinking approaches.

Merging the gamification and design thinking approaches is novel, particularly on firms' ESoIP. The paper provides a comprehensive discussion of design thinking shortcomings and the role that gamification can play in overcoming them.

This study aims at developing a comprehensive model for the analysis of electro-osmotic flow (EOF) through a fluid-saturated porous medium. To fully understand and exploit a number of applications, such a model for EOF through porous media is essential.

The proposed model is based on a generalised set of governing equations used for modelling flow through fluid saturated porous media. These equations are modified to incorporate appropriate modifications to represent electro-osmosis (EO). The model is solved through the finite element method (FEM). The validity of the proposed numerical model is demonstrated by comparing the numerical results of internal potential and velocity distribution with corresponding analytical expressions. The model introduced is also used to carry out a sensitivity analysis of the main parameters that control EOF.

The analysis carried out confirms that EO in free channels without porous obstruction is effective only at small scales, as largely discussed in the available literature. Using porous media makes EO independent of the channel scale. Indeed, as the channel size increases, the presence of the charged porous medium is essential to induce fluid flow. Moreover, results demonstrate that flow is significantly affected by the characteristics of the porous medium, such as particle size, and by the zeta potential acting on the charged surfaces.

To the best of the authors’ knowledge, a comprehensive FEM model, based on the generalised equations to simulate EOF in porous media, is proposed here for the first time.

This paper aims to provide a comprehensive literature review on modelling electro-osmotic flow in porous media.

Modelling electro-osmosis in fluid systems without solid particles has been first introduced. Then, after a brief description of the existing approaches for porous media modelling, electro-osmotic flow in porous media has been considered by analysing the main contributions to the development of this topic.

The analysis of literature has highlighted the absence of a universal model to analyse electro-osmosis in porous media, whereas many different methods and assumptions are used.

For the first time, the existing approaches for modelling electro-osmotic flow in porous have been collected and analysed to provide detailed indications for future works concerning this topic.

This paper analyses “luxemburgian” political and economic thought and tries to associate its importance with Luxemburg’s role as a socialist and as an activist in the women’s liberation movement. Luxemburg’s “feminism,” Marxism, anti-authoritarianism and independent thinking make her a figure of continuing importance within both Marxism and feminism. At the same time, she was part of a changing political and social reality and not only passed on an important legacy to economics, but also through her political activism alerted us to the dangers of anti-democratic behaviour. Similarly, her defence of internationalism and denunciation of economically motivated imperialist wars was equally original. Summing up, it is Luxemburg who originated new ways of thinking, which go beyond simple representational thought.

The purpose of this paper is to identify and characterize patterns of physical activity among office workers employed in largely sedentary occupations at a major health insurer located in the Southeastern USA.

The authors used latent class analysis to identify segments of office workers (n=239) based on their self-reported activities of daily living and exercise behaviors. The authors examined the association of demographic characteristics with segment membership, and differences in accelerometer-measured weekly minutes of light and moderate-vigorous physical activity across segments.

The authors identified two segments and labeled them “exerciser” and “non-exerciser.” Being female was associated with lower odds of membership in the “exerciser” segment (OR=0.18; 95% CI=0.06, 0.52), while those with at least a bachelor’s degree were more likely to be in the “exerciser” segment (OR=2.12; 95% CI=1.02, 4.40). Mean minutes of moderate-vigorous physical activity per week were greater for the “exerciser” segment than the “non-exerciser” segment.

Based on this sample, the authors found that office workers in sedentary occupations were roughly equally divided and distinguished by their engagement in exercise-type behaviors. The findings underscore the need for innovative workplace programming that enhances activity opportunities particularly for those that are not likely to exercise.

A scarcity of research on activity patterns among office workers inhibits development of targeted worksite activity programming. The present research reveals two segments of workers with regard to their activity patterns and suggests ways for worksites to meet their unique needs.
