A collaborative perspective in green construction risk management
No full textMany risks existing in the supply chain of green construction projects are poorly managed by traditional non-collaborative approaches leading to problems such as higher prices, inappropriate indoor environment quality, technological failures and legal battles that in turn adversely affect all stakeholders. To reduce the cases of failure in the green construction industry, it is necessary for supply chain (SC) key players to collaboratively identify, analyse and treat risks, considering benefits and concerns of all stakeholders inside the network.
This paper presents a method for collaborative risk management to provide informed advice to supply chain stakeholders to manage risks in the green construction industry. Contribution of the proposed collaborative approach is illustrated in a case study carried out in a green construction development project in Melbourne, Australia. The case study introduced in this research is sufficiently robust to provide evidence that collaborative approaches can add value to traditional methods of risk management and presents a modelling and analysis framework for assessing supply chain risks in the green construction.

Implementation of Smart Pilotage to Safeguard Pilots from Pilot Ladder Accidents
No full textThis study aims to identify and use digital technology to ensure the pilots’ lives’ safety and to avoid unnecessary delays due to vessels staying at quarantine anchorage during pandemics. The primary means for a pilot to board or disembark a ship is by a pilot ladder. Many pilots suffered severe injuries or even lost their life due to accidents involving the failure of pilot ladders. For this research, a questionnaire with five questions about the dangers and its reasons which threaten pilots’ lives, was
prepared, and distributed to professionals both in the maritime industry and port operations. Eightynine professionals from the maritime industry answered it. The most common causes affecting pilots’ safety were unsafe rigging and not securing the ladder correctly or the breaking of a defective pilot ladder. In addition, interviews made with three maritime experts about the distance pilotage. This study aims to utilize and implement the digital technology enabling pilots to sit in the port control office or
Vessel Traffic Services (VTS) office instead of going onboard a vessel. For assessing our innovation, a berthing and one unberthing scenario were designed and tested in our full mission bridge simulator by an experienced pilot. The results discovered during the debriefing sessions and the feedback from other experienced pilots and captains were satisfying, making us confident and comfortable with the innovation ide

Evaluating Bullying Effect on the Happiness and Performance of the Ship’s Crew
No full textBullying is rampant and has severe effects on the health and wellbeing of the employees. Additionally, it also undermines job satisfaction and performance, thus affecting productivity. Bullying among seafarers is widespread, and their isolation from the rest of the people while at sea can enhance aggressive behaviour. Bullying is widespread among seafarers and severely affects them in core areas of their life. There is a significant effect of bullying on mental health. However, the Omani seafarers are loyal to their jobs and claim to be happy at sea despite the challenges and hardships. While there are different forms of bullying in the workplace, verbal abuse is the most rampant. The study seeks to highlight the impact of bullying on seafarers' happiness and job satisfaction who work in a shipping company. A questionnaire with nine questions was prepared based on the authors' experience and sent by mobile phone to fifty officers and crew members working onboard. More insight into workplace bullying among seafarers is essential in formulating adequate law, thus improving seafarers' health and safety

Abstract Background and aimResearch utilization is a mechanism for transferring the results of research into practice and improving the quality of care in nursing. The aim of this study was to determine nurses’ readiness to utilize research needed for applying evidence-based practice. Materials and methodsIn this descriptive study, 375 nurses in all teaching hospitals affiliated with Tehran University of Medical Sciences were selected by stratified random sampling method. A 4-part questionnaire with open and close-ended questions including professional profile, research activities, research skills and access to research resources was used foe data collection. Content as well as face validities and Cronbach's α for reliability (0.82) were identified. Findings 85.9% of nurses had weak readiness in research utilization. Both research activities and skills were also low (71.4% and 82.7% respectively). 44% of nurses had insufficient access to research resources. A significant relationship was found between nurses' educational level, participation in research activities as well as English language skills and their readiness in research utilization. ConclusionLack of skills and inaccessibility to research findings lead to weak readiness for research utilization. With respect to the importance of utilizing research findings, organizational and administrative support, continuing education programs, well-defined processes and pathways to facilitate research utilization need to be provided for nurses.

Maritime decarbonization- the pathway, chances, developments and obstacles
No full textDecarbonization is crucial to meeting the world’s climate goals and a more sustainable future. As the globe works to cut greenhouse gas emissions and lessen the effects of climate change, decarbonizing the maritime sector has become an urgent problem in recent years. Fossil fuel combustion is the leading cause of greenhouse gas emissions, which have a role in climate change and global warming. It entails moving away from energy based on fossil fuels and toward greener, lower-carbon options, including renewable energy, energy-saving devices, and sustainable mobility. The necessity of coordination and cooperation between various stakeholders is one of the significant obstacles to decarbonizing the maritime sector. Governments, shipping firms, and other stakeholders must collaborate to develop and put into practice sustainable solutions because shipping is a global sector. In this research, the author examines the difficulties and possibilities of decarbonizing the shipping sector and the development achieved in this direction. This study investigates the decarbonization prospects available to shipping businesses, the regulatory framework, and alternatives to fossil fuels through a thorough assessment of the literature and data analysis. This article thoroughly analyses the difficulties and potential of decarbonizing the shipping sector, emphasizing fossil fuel alternatives, the regulatory environment, and the options open to shipping businesses for decarbonization. Additionally, it emphasizes the significance of stakeholder cooperation and the contribution of digital technology to the enhancement of shipping operations and the lowering of emissions
Utilización de redes energéticas inteligentes para mitigar la huella de carbono de los puertos marítimos inteligentes en aras de la sostenibilidad
No full textAccording to the European MSP Platform\u27s "Green airports and ports as multimodal hubs for sustainable and intelligent mobility" program, all ports must demonstrate integrated low-emission energy production and supply at ports and supply systems, with storage, distribution, and sustainable alternative fuel refuelling infrastructure for ships, other vehicles, and other uses. Smart seaports also balance energy demand and supply via IoT-based intelligent management.Next, seaports must reduce internal port border energy consumption or use renewable energy in compliance with sustainability, ISO 50001, and Port Energy Management Plans (PeMP). This study examines energy generation, transfer, distribution procedures and implementation to lower the seaport\u27s carbon footprint (C.F). The technique includes a "scoping review" and extensive linked resource investigation. EMS impact in smart ports lower carbon emissions is in the discussion. And finally, the conclusion contains scientific insights, thoughts, and proposals for enhancing the ports\u27 EMS in a relevant subject.Según el programa «Aeropuertos y puertos verdes como centros multimodales para una movilidad sostenible e inteligente» de la Plataforma MSP europea, todos los puertos deben demostrar una producción y suministro integrados de energía de bajas emisiones en puertos y sistemas de abastecimiento, con infraestructuras de almacenamiento, distribución y repostaje sostenible de combustibles alternativos para buques, otros vehículos y otros usos. Los puertos marítimos inteligentes también equilibran la demanda y el suministro de energía mediante una gestión inteligente basada en IoT. A continuación, los puertos marítimos deben reducir el consumo de energía en las fronteras interiores del puerto o utilizar energías renovables en cumplimiento de la sostenibilidad, la norma ISO 50001 y los planes de gestión de la energía portuaria (PeMP). Este estudio examina los procedimientos de generación, transferencia y distribución de energía y su aplicación para reducir la huella de carbono (H.C.) del puerto marítimo. La técnica incluye una «revisión del alcance» y una amplia investigación de recursos vinculados. El impacto del SME en la reducción de las emisiones de carbono de los puertos inteligentes es objeto de debate. Y por último, la conclusión contiene ideas científicas, reflexiones y propuestas para mejorar el SGA de los puertos en un tema relevant
