Is There a Causal Effect of Working Part‐Time on Current and Future Wages?

In this paper, I study the causal effects of part‐time work on current and future wages. To estimate these effects, I use a random effects model with a wage equation capturing the employment history and a dynamic multinomial probit component for the choice of employment status. Exclusion restrictions from the institutional context are exploited to support identification. The results suggest that working part‐time with few hours has a large causal effect on current wages, but more extensive part‐time work does not reduce current wages. However, both types of part‐time work lead to negative long‐term wage effects.

Port geography at the crossroads with human geography: between flows and spaces

Port research is not a new field of interest for human geographers, evidenced by numerous conceptual models and empirical cases of port evolution and development in the literature. However, several critical questions remain unanswered, notably the exact position of port geography as a subdiscipline within human geography in the past, present and future. Based on a pluralistic approach, the paper analyzes the changing waves and development of port geography as a sub-discipline of human geography, with a special focus on whether port geography has experienced a paradigm shift and, if so, when, why, and how. Also, through analyzing the major terrains of port geography research from the macro perspective, it brings a new lease of life to port geography in this rapidly changing world.

Understanding conflicting perspectives in event planning and management using Q method

There is a need to better understand the interests of actors in the planning and management of major events. The diversity of actor perspectives about an event creates a wicked problem set that event organisers and public officials find difficult to understand, let alone address. This paper focuses on problem identification as one stage in the event planning and management process. It explores how problem structuring can contribute to more effective planning and management of actors' interests. The value of Q methodology is explored through a case study of the Australian World Rally Championship. Four perspectives are identified in the problem structuring process: the Skeptics, the Materialists, the Middle-grounders and the Supporters. The findings demonstrate that Q methodology is effective in identifying the depth and breadth of different problem perspectives, providing insights into the importance of different perspectives, and can be used reflexively to anticipate and manage potential conflict.
