摘要：Rapidly increasing numbers of ships and ship sizes pose an ever–growing challenge to the maritime industry.Although statistics indicate improved levels of safety in the industry which carries 90% of the world’s trade,the risk of navigational accidents,among other issues,remains a prime concern and priority (EMSA,2010;2014).In order to address these concerns,the authors turned to another high–risk industry for inspiration.Specifically,they turned to the aviation industry,which has often been used as a source of comparisons and ideas by researchers in the maritime domain.Keeping up with the trend,the authors of this paper turn to a tried–and–tested system used widely in modern aviation:the Airborne Collision Avoidance System (ACAS).The prime idea behind ACAS is to construct two virtual 3D zones around an aircraft.These zones are dynamic,and depend on the manoeuvring characteristics of a given aircraft.If the system detects an "intruder” (another aircraft) in either of the two well–defined virtual zones,it provides warnings and/or instructions to pilots of both aircraft to take certain precautionary or emergency measures.In the current paper,the authors explore whether or not such a system is feasible for use in the maritime domain and,if so,how.The paper provides a detailed analysis of the potential benefits and drawbacks of using an ACAS–like system onboard vessels.It also discusses possible means of implementation and integration with current equipment,and explores how the introduction of e–navigation may impact the proposed solution.
其他摘要：Penelitian ini merupakan penelitian explanatory yang bertujuan untuk mengidentifikasi model perilaku berwirausaha perempuan terdidik di Sumatera Barat dengan menginvestigasi hubungan antara sikap berwirausaha,Norma Subjektif,dan Efikasi diri sebagai variabel endogen dan perilaku berwirausaha sebagai variabel eksogen.Sebagai tambahannya,penelitian ini melibatkan intensi berwirausaha sebagai variabel intervening.Kontribusi penelitian ini adalah untuk meningkatkan intensi berwirausaha bagi lulusan perguruan tinggi.Populasi adalah member IWAPI Sumbar.Sampel ditarik dengan cara stratified random sampling dengan menggunakan kuesioner.Untuk analisis data didukung dengan software SPSS 20 untuk deskriptif data dan Smart PLS untuk menganalisis model..
