The rapid growth in cruise shipping coupled with increasing public awareness of climate change has led to increasing concerns about the impact cruise shipping poses on the environment, especially regarding air emissions. This study analyses the cruise shipping network of ports in and around the emission control areas (ECAs) to understand the structural properties of the network and ports.

A complex network approach was used to analyse the network data of 239 voyages serviced by 14 international cruise lines, visiting 127 ports across 44 countries in the Caribbean Sea.

It is found that the network has a small-world property with a short average path length and a high clustering coefficient. The regulations affect connections among ports, in which most ports in ECAs have lower connections than ports outside ECAs. A few ports in ECAs play important key roles, but many ports outside ECAs play a more important role in the network because the regulations are barriers for cruise ships entering the ports.

The findings of this study have drawn useful guidelines for cruise lines and port authorities to improve their operations. Constrictive recommendations are suggested to policymakers for designing reasonable regulations to attract more cruise shipping to travel in ECAs.

The purpose of this study is to build a proposal for an integrated analysis / evaluation / decision / implementation framework to suit entrepreneurial companies intending to redefine their strategic behaviours and their competitive schemes in the global environment.

A conceptual approach, based on theoretical perspectives relating to globalisation-based management and decision-making of entrepreneurs, is adopted.

The paper presents a conceptual framework useful for supporting entrepreneurial decisions for global strategies, drawing on an integrated analysis of external environment and internal components, with a specific focus on the entrepreneur's characteristics in terms of cognitive and emotional profiles. It is suggested to adopt a logical process aimed at identifying which strategic levers are available for entrepreneurial players to implement their strategies.

Entrepreneurial decision-making may benefit from an integrated framework which helps entrepreneurs, who aim to compete in the global marketplace, to explore and exploit all the key factors useful to defining their strategies.

There is a lack of decision-making frameworks that put the entrepreneur at the centre and, at the same time, present a potential balance between the external factors (globalisation drivers and local opportunities) and the resources and competences required to manage risks and difficulties of the global environment (internal factors). The originality of the proposed framework consists in filling this gap. Moreover, this framework can be useful for “re-born global” or “global-again” firms that are currently a neglected typology of studied firms.

Previous literature suggests that exposure to trauma has both positive and negative impacts on leadership and leadership development, although there is a lack of empirical research. This exploratory study compared military leaders’ use of transformational leadership styles (TLS) before and after trauma exposure from the followers’ perspective. This study used a retrospective pretest design to survey veteran and active duty military personnel. Significant differences were found between pre- and post-trauma exposure TLS ratings, with a mean decline in the TLS after trauma exposure. The analysis of the open-ended questions indicated a reduction in the use of the TLS after trauma, but identified positive changes in some cases. There was no evidence that changes in the TLS were concentrated in any of the five styles.

Using a panel of over 433,000 college students from over 600 institutions of higher education in the USA, we investigate students’ opinions of leadership skill development during their undergraduate tenure.

The data used in this analysis come from the Higher Education Research Institute, which runs the Cooperative Institutional Research Program (CIRP) housed at the University of California, Los Angeles. Among others, the CIRP administers two surveys known as The Freshman Survey (TFS) and the College Senior Survey (CSS).

The present research supports the extant literature and conventional wisdom of academic and student affairs professionals with regards to engagement in leadership classes or training where students have an opportunity to increase their knowledge bases through course content, and when there are opportunities for them to apply leadership principles, the students are more likely to report an increase in leadership capacity upon completion of their collegiate degree.

If colleges and universities are serious about fulfilling their espoused visions, then it is essential that awareness of leadership courses and applied opportunities be heightened and made a strategic priority to ensure resources are allocated in appropriate places to support these key efforts. It also suggests greater collaboration between academic and student affairs, as well as other departments (e.g. athletics and centers), is needed, as well as prioritizing experiential learning.
