As sustainability is becoming a common practice in planning transport systems and mobility services, the designation and management of gender issues are of paramount importance. TInnGO is a European Project that has developed a network of 10 national Hubs to build the capacity to generate and apply evidence on gender equality and transport issues at the European level. This paper presents the project activities by introducing a relevant framework and exploring user mobility experiences based on gender to identify diversified needs and requirements. This process relies on the combination of a review of current gender-oriented experiences and practices in mobility with focus group activities conducted in four different EU cities. The insights obtained from these activities supported the design of a survey to collect information on socioeconomic, personal, and operational aspects to serve a gender-oriented transport analysis for all the Hubs. These preliminary analyses identified the main issues related to the female mobility experience, namely safety, security, accessibility, and transport reliability. Future research on the data collected through the survey would help operators in successfully improving their mobility offer to women.

Rail Systems

Condition monitoring of rail transport systems has become a phenomenon of global interest over the past half a century. The approaches to condition monitoring of various rail transport systems—especially in the context of rail vehicle subsystem and track subsystem monitoring—have been evolving, and have become equally significant and challenging. The evolution of the approaches applied to rail systems’ condition monitoring has followed manual maintenance, through methods connected to the application of sensors, up to the currently discussed methods and techniques focused on the mutual use of automation, data processing, and exchange. The aim of this paper is to provide an essential overview of the academic research on the condition monitoring of rail transport systems. This paper reviews existing literature in order to present an up-to-date, content-based analysis based on a coupled methodology consisting of bibliometric performance analysis and systematic literature review. This combination of literature review approaches allows the authors to focus on the identification of the most influential contributors to the advances in research in the analyzed area of interest, and the most influential and prominent researchers, journals, and papers. These findings have led the authors to specify research trends related to the analyzed area, and additionally identify future research agendas in the investigation from engineering perspectives.

Perceived Power

Impelled by a desire to control, suppress, and deny emotional response, stoic individuals may act out their pent-up emotions on relational partners by provoking conflict and/or engaging in partner-directed violent and aggressive behaviors. However, little is known regarding what factors can push stoics over the edge from remaining quiet or avoiding revealing frustrations to initiating aggressive behavior. This relationship between stoicism and aggression is important to consider in serial arguments, where the repetitive nature of a conflict may become increasingly difficult for stoics to manage internally. Here, we examined the influence of stoicism on verbal aggression in serial arguments between romantic partners. We additionally considered the effects of power, perceived resolvability, and argument frequency on the relationship between stoicism and verbal aggression. Using a survey design with a sample of 281 individuals involved in a romantic relationship, we observed that stoicism is positively associated with verbal aggression in serial arguments. While perceived power and resolvability did not moderate the relationship between stoicism and verbal aggression, argument frequency about a serial argument topic was a significant moderator. The results of this study imply that stoicism plays an important role in explaining aggressive tactics in conflict. A high argument frequency about a conflict topic may lead to a buildup of unexpressed emotions, particularly anger, in stoic individuals, resulting in an explosive release of violence and aggression toward a romantic partner. Unique results on the relationship between stoicism and power and directions for future research are discussed.

Many of today´s world wide challenges such as climate change, water supply and transport systems in cities or movements of crowds need spatio-temporal data to be examined in detail. Thus the number of examinations in 3D space dealing with geospatial objects moving in space and time or even changing their shapes in time will rapidly increase in the future. Prominent spatio-temporal applications are subsurface reservoir modeling, water supply after seawater desalination and the development of transport systems in mega cities. All of these applications generate large spatio-temporal data sets. However, the modeling, management and analysis of 3D geo-objects with changing shape and attributes in time still is a challenge for geospatial database architectures. In this article we describe the application of concepts for the modeling, management and analysis of 2.5D and 3D spatial plus 1D temporal objects implemented in DB4GeO, our service-oriented geospatial database architecture. An example application with spatio-temporal data of a landfill, near the city of Osnabrück in Germany demonstrates the usage of the concepts. Finally, an outlook on our future research focusing on new applications with big data analysis in three spatial plus one temporal dimension in the United Arab Emirates, especially the Dubai area, is given.

Community-based green care initiative is an intervention geared towards satisfying the environmental, social, psychological, medical and material care for stimulating healthy well-being of children, adolescence and adults. Evidence-based studies have established that there is continual degeneration of self-esteem among adolescence in developing countries including Nigeria due to problems associated with unsustainable parenting styles and teaching patterns. It is in the light of this, the study examines a community-based green care initiative as a catalyst for sustainable parenting styles, teaching patterns and child self-esteem in Ogun State, Nigeria. The study adopted exploratory survey design and tested three hypotheses on the subject matter. A self-structured questionnaire and in-depth interview guide were used for data collection. Quantitative data were analysed through percentage distribution table and multiple regressions while qualitative data were analysed using direct quotes. Findings were discussed with reference to relevant empirical literatures and future research highlighted.

Sustainability Challenges

In recent years, there is a need for new methods and frameworks for planning transport systems, improving their efficiency, and addressing globalisation and sustainability challenges. In addition, the use of existing capacities and infrastructure has raised significant issues in the transport sector. To achieve an economically, environmentally, and socially sustainable logistics ecosystem, Benoit Montreuil introduces the concept of “Physical Internet” (PI) to increase the efficiency and effectiveness of logistics networks. As a ground-breaking transportation philosophy, the PI aims to revolutionise freight and logistics transport. Moreover, the PI can enhance logistics productivity through the organisation of large-scale pooling. Similar to Digital Internet that conveys data, the PI strives to connect, synchronise, and ship regular modular containers from the point of origin to an exact destination, thereby creating robust and collaborative logistics networks. While the literature on the PI is relatively growing, there is still a lack of reviews that synthesise this knowledge body, identify current trends and gaps, and advance the research more broadly.  Therefore, this study aims to investigate the potentials of the PI for the development of sustainable logistics networks. Overall, 59 studies are selected from leading academic databases and further analysed. The review findings reveal that most scholars focus on the optimisation of transport at the tactical and organisational stage while devoting little attention to the contribution of the PI to the social sustainability of logistics compared to the economic and environmental aspects.

The Impact

Research background: The economic impact of investing in new transport capacity or improving existing ones is complex and often indirect. Loans for infrastructure are often needed, but they cannot create sufficient conditions for economic growth. Investments in transport infrastructure require public funding. An assessment of their cost-effectiveness is needed to ensure a reasonable and acceptable allocation. Relevant economic, environmental and social effects must be taken into account. There is a growing concern in the transport sector about decisions on the development of the transport system and the effects of scale and externalities they produce. Planners and decision-makers need to know more about the wider economic impact of individual infrastructure projects and transport policies in general. Purpose of the article: This paper aims to present the most important theoretical and practical aspects of the importance of transport investment worldwide, at European level and Romania. Investments in transport infrastructure will not improve the economic vitality of a region unless it has sufficient economic capacity and employment, land use and economic development policies. Methods: This article starts from the hypothesis of the influence of globalization on the development of transport systems in general and applies as a case study on Romania. The paper was based on the analysis of transport legislation, as well as data sets for the period 2011-2019, to observe the gradual development of all types of transport. Findings & Value added: Following these researches, the link between globalization and investments in transport systems was found by emphasizing accessibility to new infrastructures, new horizons and development plans for the main types of transport, which is a key element in economic activity. The main results were disseminated throughout the article and it adds value through the analysis created at global and regional level (at European level) and the interpretation of statistical data related to transport investments.

Abstract We discuss an evidence-based approach to guiding real-time design decisions during the course of survey data collection. We call it responsive and adaptive design (RAD), a scientific framework driven by cost-quality tradeoff analysis and optimization that enables the most efficient production of high-quality data. The notion of RAD is not new; nor is it a silver bullet to resolve all the difficulties of complex survey design and challenges. RAD embraces precedents and variants of responsive design and adaptive design that survey designers and researchers have practiced over decades. In this paper, we present the four pillars of RAD: survey process data and auxiliary information, design features and interventions, explicit quality and cost metrics, and a quality-cost optimization tailored to survey strata. We discuss how these building blocks of RAD are addressed by articles published in the 2017 JOS special issue and this special section. It is a tale of the three perspectives filling in each other. We carry over each of these three perspectives to articulate the remaining challenges and opportunities for the advancement of RAD. We recommend several RAD ideas for future research, including survey-assisted population modeling, rigorous optimization strategies, and total survey cost modeling.

SUMMARY One of the most salient features of Bacillus subtilis and related bacilli is their natural capacity to secrete a variety of proteins into their environment, frequently to high concentrations. This has led to the commercial exploitation of bacilli as major “cell factories” for secreted enzymes. The recent sequencing of the genome of B. subtilis has provided major new impulse for analysis of the molecular mechanisms underlying protein secretion by this organism. Most importantly, the genome sequence has allowed predictions about the composition of the secretome, which includes both the pathways for protein transport and the secreted proteins. The present survey of the secretome describes four distinct pathways for protein export from the cytoplasm and approximately 300 proteins with the potential to be exported. By far the largest number of exported proteins are predicted to follow the major “Sec” pathway for protein secretion. In contrast, the twin-arginine translocation “Tat” pathway, a type IV prepilin-like export pathway for competence development, and ATP-binding cassette transporters can be regarded as “special-purpose” pathways, through which only a few proteins are transported. The properties of distinct classes of amino-terminal signal peptides, directing proteins into the various protein transport pathways, as well as the major components of each pathway are discussed. The predictions and comparisons in this review pinpoint important differences as well as similarities between protein transport systems in B. subtilis and other well-studied organisms, such as Escherichia coli and the yeast Saccharomyces cerevisiae. Thus, they may serve as a lead for future research and applications.

Purpose The rise of new information and communication technologies forms the cornerstone for the future development of work. The term Industry 4.0 refers to the vision of a fourth industrial revolution that is based on a network of autonomous, self-controlling, self-configuring, knowledge-based, sensor-based and spatially distributed production resources. All in all, different forms of the application of the Industry 4.0 concept can be observed, ranging from autonomous logistic transport systems drawn upon the idea of swarm intelligence to smart knowledge management systems. This paper aims to develop a theoretical framework to analyze different applications of Industry 4.0 on an organizing continuum. The general research questions are: What forms of organizing digitalized work lead to the reproduction of routines, and what forms foster innovation within Industry 4.0? The authors thus analyze the consequences of different forms of organizing work on workers’ perceptions and the results of the working process. Design/methodology/approach This paper provides case studies for different stages of the organizing continuum in the context of Industry 4.0. The cases and a further analysis of all 295 funded projects are based on the Platform Industry 4.0 Map, which is part of the Industry 4.0 initiative of the German Federal Ministry of Economic Affairs and Energy and the German Federal Ministry of Education and Research. The consequences for people acting in such organizational and digitally supported structures are discussed. Findings A variety of applications of Industry 4.0 can be found. These applications mainly vary in the dimensions of the degree of formalization, the location of control authority, the location of knowledge and the degree of professionalization. At the right side of the organizing continuum, the digitalization organizes a work environment that supports highly qualified humans. They have broad leeway and a high degree of autonomy to design and create innovative forms of digitalization for tomorrow. At the left side of the organizing continuum, Industry 4.0 structures a work environment with narrow leeway, a low degree of autonomy and a top-down structure of control authority predetermined by digital applications. In this case, employees fill the gaps the machines cannot handle. Research limitations/implications As the paper focuses on Industry 4.0 developments in Germany, the comparability with regard to other countries is limited. Moreover, the methodological approach is explorative, and broader quantitative verification is required. Specifically, future research could include quantitative methods to investigate the employees’ perspective on Industry 4.0. A comparison of Industry 4.0 applications in different countries would be another interesting option for further research. Practical implications This paper shows that applications of Industry 4.0 are currently at a very early stage of development and momentarily organize more routines than innovations. From a practical point of view, professional vocational and academic training will be a key factor for the successful implementation of digitalization in future. A joint venture of industry and educational institutions could be a suitable way to meet the growing demand for qualified employees from the middle to the right-hand of the organizing continuum in the context of Industry 4.0. Social implications Industry 4.0 is designed by men, and therefore, humans are responsible for whether the future work situation will be perceived as supportive or as an alienated routine. Therefore, designers of Industry 4.0, as well as politicians and scientists, absolutely must take the underlying outcomes of digitalized work into account and must jointly find socially acceptable solutions. Originality/value This paper provides a promising avenue for future research on Industry 4.0 by analyzing the underlying organizational structures of digital systems and their consequences for employees. Moreover, the paper shows how Industry 4.0 should be organized to simply reproduce routines or to support innovation.

The concluding chapter begins by summarizing and discussing the insights that this book has generated. It has addressed three aspects that have received scant attention in existing research: The importance of analyzing the Eurozone crisis in comparative perspective, the importance of examining the whole range of policy options, including the ones not chosen, and the importance of analyzing crisis politics not just in deficit-debtor, but also in surplus-creditor countries. Because the bulk of the book’s analyses have focused on domestic distributive struggles, the concluding chapter turns to the question to what extent the book’s approach is useful for understanding the distributive struggles on the European level as well. For this purpose, the chapter examines how surplus and deficit states positioned themselves with regard to the core EMU-related issues and reforms that were discussed in the European Council during the Eurozone crisis. The analysis shows that on policy issues related to questions of adjustment and financing, deficit and surplus countries aligned in opposing camps. Moreover, creditor-surplus countries managed to secure policy decisions in line with their preferences on almost all adjustment-related policy issues. This meant that deficit countries had to carry the bulk of the adjustment burden. In contrast, surplus countries showed more willingness to compromise on issues related to financing. The chapter concludes with a discussion of the policy implications of the findings and offers an agenda for future research.
