Freight Market

One of the major goals of the European Union's transport policy is to increase the market share of rail freight transports. With the Internet, globalization, and just-in-time production, the future of freight transport has moved to high-value and lightweight goods. Rail freight has had difficulty entering this market. Thus, a multipronged strategy is required for improving the rail freight market in which freight is consolidated and transported in Europe by encouraging new players to enter the market. A key pillar of this strategy is the introduction of freight exchanges that are based on principles similar to those of power exchanges. The latter are already well established and operational in the energy sector. This paper describes the market and operational requirements for efficient and reliable freight exchanges in the European freight market from which the rail sector can profit. Lessons learned from the energy sector were reviewed and applied in the context of the rail freight sector in this study. The analysis implies that for rail freight to function, as a pre requisite the freight exchanges would need to provide high liquidity in the market and be neutral to all parties, including shippers and forwarders. Furthermore, to facilitate competition, such exchanges would have to send price signals in the market like power exchanges do. The exchanges would allow automatic bidding, and the transaction process would be efficient and reliable. The rail freight operators would need to provide standardized indistinguishable products to serve as commodities on the freight exchanges.

The Right

Just-in-time adaptive intervention (JITAI) has gained attention recently and previous studies have indicated that it is an effective strategy in the field of mobile healthcare intervention. Identifying the right moment for the intervention is a crucial component. In this paper the reinforcement learning (RL) technique has been used in a smartphone exercise application to promote physical activity. This RL model determines the ‘right’ time to deliver a restricted number of notifications adaptively, with respect to users’ temporary context information (i.e., time and calendar). A four-week trial study was conducted to examine the feasibility of our model with real target users. JITAI reminders were sent by the RL model in the fourth week of the intervention, while the participants could only access the app’s other functionalities during the first 3 weeks. Eleven target users registered for this study, and the data from 7 participants using the application for 4 weeks and receiving the intervening reminders were analyzed. Not only were the reaction behaviors of users after receiving the reminders analyzed from the application data, but the user experience with the reminders was also explored in a questionnaire and exit interviews. The results show that 83.3% reminders sent at adaptive moments were able to elicit user reaction within 50 min, and 66.7% of physical activities in the intervention week were performed within 5 h of the delivery of a reminder. Our findings indicated the usability of the RL model, while the timing of the moments to deliver reminders can be further improved based on lessons learned.

Online Sources

This paper describes lessons learned from developing the most recent Balanced Corpus of Modern Latvian (LVK2018) from various online sources. Most of the new corpora are created from data obtained from various text holders, which requires cooperation agreements with each of the text holders. Reaching these cooperation agreements is a difficult and time consuming task and may not be necessary if the resource to be created is not of hundred millions of size. Although there are many different resources available on the Internet today for a particular language, finding viable online resources to create a balanced corpus is still a challenging task. Developing a balanced corpus from various online sources does not require agreements with text holders, but it presents many more technical challenges, including text extraction, cleaning and validation.

Rapid Transformation

Resumen:La organización de la producción ha venido sufriendo una rápida transformación desde hace casi dos décadas, con los cambios de los equipos de trabajo, las técnicas administrativas de calidad total y la producción justo a tiempo. Estas transformaciones han resultado en una mejora en la productividad en el trabajo, pero también en las repercusiones negativas sobre la vida de los trabajadores. Si las consecuencias positivas de la transformación del proceso de trabajo con respecto a la productividad están más que compensadas por las consecuencias negativas en las condiciones de trabajo, es posible que el movimiento de transformación del proceso de trabajo sea nocivo para la sociedad como un todo.Palabras clave : organización de la producción; equipos de trabajo; técnicas administrativas; calidad total; producción justo a tiempo; productividad. Abstract:The organization of production has undergone a rapid transformation for almost two decades, through changes in the work teams, the total-quality administrative techniques, and the just-in-time production. These changes have resulted in a better labor productivity, but also in negative effects on workers' lives. If positive consequences of the transformation of labor process with regard to productivity are more than compensated by the negative impact on working conditions, the labor process's change movement can be harmful to society as a whole.Key words: organization of production; work teams; administrative techniques; total quality; just-in-time production; productivity.

Web Based Education

This article reviews the development of three Web-based education resources and the potential for each of these resources to meet the needs of users for a 'killer app'. Three case studies (the Annotated List of Education Journals, the IDEAS Portal Web Site and the Eisenhower National Clearinghouse Web Site)review the purpose, audience, content, funding, publicity and structure of the sites. Differences in staffing, funding and the centrality of these sites to the mission of their sponsoring institutions impacted the growth of these sites. Technological changes and the diffuse nature of the Internet also impacted the development of these resources.
