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.

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.

The purpose of this paper is to reflect upon how encountering trauma unexpectedly in the field informs the doing of fieldwork.

A reflexive essay approach was adopted to explore traumatic incidents in extreme contexts. Written vignettes, interviews, field notes and information conversations served as the bases for reflections.

Four themes arose from the reflections (Bracketing, Institutional Pressure, Impact on Research and Unresolvedness). It was suggested that researchers engaged in extreme context research, and management and organization studies scholars engaged in dangerous fieldwork more broadly, are under institutional pressure to continue work that may put themselves in harm's way. Traumatic experiences also shape and reflect the researcher's identity, which informs choices about current and future research projects.

It was suggested that scholars will benefit from reading the accounts of others to reduce the burden of isolation that can accompany traumatic field experiences.

Exploring single traumatic events enabled in engaging with trauma encountered unexpectedly and directly in the field. The reflections reveal the effects of psychological and physical trauma on researchers, and highlight how trauma impacts the research process.

Firefighters are daily confronted with adverse, unpredictable and demanding situations. It is a dangerous profession that puts firefighters at risk of developing burnout. Although the literature has already identified personal and work-related factors of burnout, the examination of specific factors explaining burnout among volunteer and career firefighters is still needed. The purpose of this study is to investigate the explaining role of personal and work-related factors on volunteer and career firefighters’ burnout.

A nonrandom convenience sample of 250 firefighters (67% volunteer; M_age = 31.88) completed a sociodemographic questionnaire, the Oldenburg Burnout Inventory, the Proactive Coping Scale and a standard of living subscale item. Hierarchical multiple linear regression models were tested. Fisher’s criterion was considered, with p-values lower than 0.05 interpreted as statistically significant.

Personal and work-related factors accounted for 18% of volunteer and 31% of career firefighters’ variations in burnout. Personal factors offered a greater contribution explaining volunteer and career firefighters’ burnout. Still, variations in the role played by age, family responsibilities, proactive coping and satisfaction with standard of living on burnout were found among volunteer and career firefighters. Taking the work-related factors into account, working in rotative shifts constituted a risk factor for career firefighters’ burnout.

This study advances the understanding about the role of personal and work-related factors in volunteer and career firefighters’ burnout.

This study adds information about specific factors explaining burnout among voluntary and career firefighters. It deepens existing knowledge on variations in the role played by age, family responsibilities, work conditions, proactive coping and satisfaction with standard of living on the burnout of volunteer and career firefighters.

Even though every decision a leader makes carries an element of risk, no review on the topic of leadership and risk has appeared in highly-ranked management journals in the past 20 years. This is in contrast to the discipline of psychology in which leadership and risk receives considerable attention, particularly in the field of heroism studies. In the context of the established body of research on the topic of leadership and risk in the discipline of psychology, this review therefore explores the research on leadership and risk in highly-ranked management studies’ journals.

The review was conducted in five stages. During phase 1, journal rankings were used as basis to determine which highly-ranked journals to include in the review. Phase 2 focused on identifying all relevant articles in the journals included in our review. We searched for articles published from 2000 to 2021 with the words “risk” or “danger” and “leader” or “leadership” in their abstracts. In phase 3, the author analysed the abstracts of the articles in depth to determine whether the keywords were included on the basis of an explicit scholarly reflection or research on leadership and risk. Phase 4 focused on analysing articles' treatment of leadership and risk, and assigning key words and key phrases. Finally, during phase 5 key words and key phrases were clustered together thematically.

This study analysis yielded six thematic clusters. The first two clusters – on risk appetite of followers and leaders – are closely related. In total, 12 journal articles explored these themes. The remaining thematic clusters contain four and seven articles each. These clusters are risk, creativity and innovation; risk and failure; risk in dangerous contexts; and risk and gender. Nine of the selected articles did not fit in any of the thematic clusters.

The review reveals a significant lack of research on leadership and risk in highly-ranked management studies’ journals. The author found that the topic of leadership and risk is approached in a binary fashion: successful leaders are viewed as using risk to drive innovation and unsuccessful leaders fail because of risk. The author argues that the heroic bias in leadership research could be partly blamed for this binarism. In practical terms, the author highlights that the growing importance of chief risk officers – leaders appointed to deal with company risk – indicates a clear need for research on leadership and risk in general management studies’ journals.
