Sustainable inland transportation [PDF]

Inland navigation is often mentioned as a ‘green’ alternative for the two other main inland transport modes: rail and road transport. In order to investigate the opportunities for inland navigation we first analyze the competitive position of inland ...

Audio‐guided exercise at home: Preliminary findings from a pilot study on physical activity for people with low vision

PM&R, EarlyView.
Abstract Background: Individuals with severe visual impairments frequently refrain from regular physical activity due to multiple barriers, including transportation difficulties, financial constraints, and limited availability of exercise programs tailored to their needs. These factors often contribute to a gradual decline in mobility and independence.

Conjugated Polymers Engineered for Flexible/Stretchable Electronics

Journal of Polymer Science, EarlyView.
This review highlights glass transition temperature (Tg) as the central parameter linking molecular structure to device performance in conjugated polymers. By tuning backbone rigidity, side‐chain architecture, and dynamic bonding, Tg governs the balance between π–π stacking–enabled charge transport and mechanical compliance.

When do firms learn by hiring? How complexity moderates the value of new knowledge

Strategic Management Journal, EarlyView.
Abstract Research Summary Organizations often hire employees hoping to acquire new knowledge. While the literature has paid considerable attention to the role of the characteristics of the source of knowledge, the recipient firm, and the knowledge being transferred, it has largely overlooked those of the knowledge being replaced.

Joint optimization of vessel scheduling and tugboat allocation in seaports with one-way navigation channels

Frontiers in Marine Science
With the continuous growth of port traffic volumes, limited navigation channel capacity and tugboat resources have emerged as major bottlenecks to port service efficiency, particularly in ports with one-way channel configurations, where vessel congestion

On the Effect of Tugboat Assistance in Harbour-III : A Study on the Standard of Tugboat Assistance

The Journal of Japan Institute of Navigation, 1995
This paper discusses a conventional standard of tugboat assistance in a harbour using a mathematical model. Diagrams show required tug-power for each element of the harbour manoeuvres and for each ship type. The turning and drifting motion in a harbour is the most typical combined ship handling manoeuvre and the final position of this motion is ...

Looking at quality through a systems lens—Applying systems thinking to the Australian National Disability Insurance Scheme

Australian Journal of Public Administration, EarlyView.
ABSTRACT It is widely recognised that many policy systems are complex, requiring collaboration across different organisations and sectors to address socioeconomic outcomes and inequalities. Yet, the public policy literature is dominated by rational–technical frameworks that struggle to understand complex systems. This paper applies ideas from the field

Crisis, temporality and governmental policy agendas: The cases of Finland and Sweden

Scandinavian Political Studies, EarlyView.
Abstract Crises transform the temporal orientation of political decision‐making. They demand immediate and decisive action and thus convert time into a means of political control. In these circumstances, assessing the long‐term consequences of proposed policies with respect to welfare, sustainability or justice also becomes demanding.
