For the purpose of reducing the incidence of hazardous materials transport accident, eliminating the potential threats and ensuring their safety, aiming at the shortcomings in the process of current hazardous materials transportation management, this paper aims to construct the framework of hazardous materials transportation safety management system under the vehicle-infrastructure connected environment.

The system takes the intelligent connected vehicle as the main supporter, integrating GIS, GPS, eye location, GSM, networks and database technology.

By analyzing the transportation characteristics of hazardous materials, this system consists of five subsystems, which are vehicle and driver management subsystem, dangerous sources and hazardous materials management subsystem, route analysis and optimization subsystem, early warning and emergency rescue management subsystem, and basic information query subsystem.

Hazardous materials transportation safety management system includes omnibearing real-time monitoring, timely updating of system database, real-time generation and optimization of emergency rescue route. The system can reduce the transportation cost and improve the ability of accident prevention and emergency rescue of hazardous materials.

It is quite universal for high-speed turnouts to be exposed to the wear of the stock rail of the switch rail during the service process. The wear will cause the change of railhead profile and the relative positions of the switch rail and the stock rail, which will directly affect the wheel–rail contact state and wheel load transition when a train passes the turnout and will further impose serious impacts on the safety and stability of train operation. The purpose of this paper is to provide suggestions for wear management of high-speed turnout.

The actual wear characteristics of switch rails of high-speed turnouts in different guiding directions were studied based on the monitoring results on site; the authorized wear limits for the switch rails of high-speed turnout were studied through derailment risk analysis and switch rail strength analysis.

The results show that: the major factor for the service life of a curved switch rail is the lateral wear. The wear characteristics of the curved switch rail of a facing turnout are significantly different from those of a trailing turnout. To be specific, the lateral wear of the curved switch rail mainly occurs in the narrower section at its front end for a trailing turnout, but in the wider section at its rear end when for a facing turnout. The maximum lateral wear of a dismounted switch rail from a trailing turnout is found on the 15-mm wide section and is 3.9 mm, which does not reach the specified limit of 6 mm. For comparison, the lateral wear of a dismounted switch rail from a facing turnout is found from the 35-mm wide section to the full-width section and is greater than 7.5 mm, which exceeds the specified limit. Based on this, in addition to meeting the requirements of maintenance rules, the allowed wear of switch rails of high-speed turnout shall be so that the dangerous area with a tangent angle of wheel profile smaller than 43.6° will not contact the switch rail when the wheel is lifted by 2 mm. Accordingly, the lateral wear limit at the 5-mm wide section of the curved switch rail shall be reduced from 6 mm (as specified) to 3.5 mm.

The work in this paper is of reference significance to the research on the development law of rail wear in high-speed turnout area and the formulation of relevant standards.

Inpatient violence is a substantial problem in psychiatric wards and de-escalation is difficult. When managing instances of violence through verbal techniques fail, mental health-care staff may use restrictive practices. The Six Core Strategies and debriefing exist for managing violence and restrictive practices in different mental health settings. Debriefing is used to get patients’ views on restrictive practices, ensure proper patient care and strengthen the role of patients as experts. This study aims to provide new information on debriefing implementation and how debriefing was used among different patient groups in a forensic hospital.

Quantitative seclusion time and debriefing reports (n = 524) were examined with Poisson regression analysis. Fisher’s exact test was used to determine the associations between debriefing and seclusion/restraint.

Debriefing (n = 524) was provided in 93% of violent episodes, which is an excellent result on an international level. There was significant variation in how often debriefing was used (p < 0.001) among different patient groups, i.e. dangerous, difficult-to-treat patients and criminal offenders whose sentences have been waived. Previous debriefing research has rarely specified what types of psychiatric patients have been subjected to seclusion or restraint.

The implementation of debriefing requires multiprofessional work within the organization and wards.

Debriefing seems to stimulate reflection at every level of a health-care organization, which fosters learning and can ultimately change clinical practices. The use of debriefing can strengthen the role of patients as well as professionals.

This study aims to explore the risk level of pufferfish and lionfish by comparing them among Turkish marines. In addition, this study focuses on comparing pufferfish with lionfish to determine which one is more dangerous for marine economics in Türkiye.

This study employs descriptive content analysis to give some qualitative evidence for the related literature. As a sample case, Türkiye was selected in the context of being a country in the Mediterranean Basin. By reviewing recent news, reports and publications, this study firstly will conclude how invasive alien marine species affect Turkish marines. Then, pufferfish and lionfish will be compared together to determine the risk level of these species for Turkish marine economics.

As a result of descriptive findings, it is seen that captured fishery has been declined in Turkey recently due to many factors including climate change, global warming, overfishing, environmental pollution and attack of invasive alien species. Pufferfish and lionfish are seen as the most spread marine species in Turkish marines. When comparing pufferfish with lionfish, it is seen that pufferfish is more dangerous than lionfish for Turkish marine economics.

This study provides descriptive and original findings as a result of comparison of pufferfish and lionfish due to their impact on Turkish marine economy. It is thought to give useful importation for the fight against invasive alien marine species in the Mediterranean Basin. Future studies can investigate different invasive alien marine species and their impacts on marine economics in the Mediterranean Basin.

Based on the Turkish cases, it is determined that there should be different policies for fight against invasive alien marine species in the Mediterranean Sea. Each marine species has different impacts on seafood market. Some of marine species can be consumed as a seafood product but some of them can't be consumed that policy makers should develop other strategies such as catching them to reduce their population in the local marines.

The spread of invasive alien marine species is still continuing in the Mediterranean Basin. Each country has been affected by the attack of invasive alien marine species. To keep sustainable seafood market and marine economics, countries should both implement common policies and develop policies specific to threats in their own countries.

This study reveals key points in the rise of invasive alien marine species in Turkish marines at first. The main contribution of this study is to be a recent sample for a country which is under attack by invasive alien marine species by giving a comparison of pufferfish and lionfish.

Non-fatal strangulation (NFS) is a dangerous form of domestic violence. We need to understand and address the challenges of prosecuting offences of NFS to help ensure the safety of women and children. This policy brief draws on an examination of prosecution case files involving NFS. It identifies the key challenges and makes recommendations for responding to them.

The purpose of this paper was to examine smallholder farmers’ perceptions of climate change risks, adaptation responses and the links between adaptation strategies and perceived/experienced climate change risks in South Gondar, Ethiopia.

This paper used a convergent mixed methods design, which enables us to concurrently collect quantitative and qualitative data. Survey data was collected from 352 households, stratified into Lay Gayint 138 (39%), Tach Gayint 117 (33%) and Simada district 97 (28%). A four-point Likert scale was used to produce a standardised risk perception index for 14 climate events. Moreover, using a one-way analysis of variance, statistical differences in selecting adaptation strategies between the three districts were measured. A post hoc analysis was also carried out to identify the source of the variation. The findings of this paper are supplemented by qualitative data gathered through focus group discussions and key informant interviews of households who were chosen at random.

The standardised climate change risk perception index suggests that persistent drought, delayed onset of rainfall, early termination of rainfall and food insecurity were the major potentially dangerous climate change risks perceived by households in the study area. In response to climate change risks, households used several adaptation strategies such as adjusting crop planting dates, crop diversification, terracing, tree planting, cultivating drought-tolerant crop varieties and off-farm activities. A Tukey’s post hoc test revealed a significant difference in off-farm activities, crop diversification and planting drought-tolerant crop types among the adaptation strategies in the study area between Lay Gayint and Simada districts (p < 0.05). This difference reconfirms that adaptation strategies are location-specific.

Although many studies are available on coping and adaptation strategies to climate change, this paper is one of the few studies focusing on the linkages between climate change risk perceptions and adaptation responses of households in the study area. The findings of this paper could be helpful for policymakers and development practitioners in designing locally specific, actual adaptation options that shape adaptation to recent and future climate change risks.

With team-based structures replacing traditional hierarchical systems, the purpose of this paper was to explore the concept of shared leadership and its impact on improving team performance. The five underlying mechanisms that form the components which drive shared leadership, namely (1) trust, (2) empowerment, (3) age and maturity, (4) fair reward, and (5) dispositions and beliefs, provide readers with a practical understanding of how to attain, maintain, and regain shared leadership for the performance of teams in organisations today. In addition, a focus on shared leadership in other team contexts, such as sport, unconventional and multicultural environments is also discussed to aid the progression of shared leadership research and broaden its application beyond traditional business and managerial contexts.

The Black Sea region has become as an important energy transit route for Caspian and Russian oil and natural gas to western markets. Since 1996 the quantity of oil exported from the Black Sea through the Turkish Straits and the number of transiting tankers has doubled and will continue to expand. However, these are also two waterways where the risk of either an accidental or intentional disaster is significant bringing serious repercussions for energy supply security. This paper will analyze measures taken by Black Sea coastal States to provide for secure ports and shipping against accidental and intentional disasters. The paper will examine the role of technology, such as satellite based VTS providers in the Black Sea, implementation of the ISPS Code, the role of the relatively new BlackSeaFor in providing both port and navigational security. The paper will further make recommendations for further improvements for enhancement of security emergency response planning. In addition, the paper will examine current security measures taken by the Turkish Administration for oil transportation through the Turkish Straits.

Bystander apathy has been a source of debate for decades. In the past half-century, psychologists developed theoretical frameworks to understand bystander activity, commonly referred to as bystander intervention models (BIMs). More recently, BIMs have been modified to facilitate initiatives to prevent various forms of online victimization. This chapter begins with a review of BIMs and recent applications of bystander intervention research to online environments. We also present several future directions for research along with applications for reducing technology-facilitated violence, including programming recommendations and theoretical development.
