Abstract

Purpose

Personnel who work in emergency medical services (EMS) face work environments which are high stress. These can lead to burnout, secondary traumatic stress (STS), and a reduction of compassion satisfaction (CS). However, very little is known about what individual and work factors influence these negative coping mechanisms in EMS personnel. It is also unknown how perceived organizational and coworker support, debriefing methods, or individual characteristics are associated with the aforementioned coping mechanisms in EMS personnel. The paper aims to discuss these issues.

Design/methodology/approach

A cross-sectional administration of surveys to Florida EMS personnel was done. A total of 351 individuals who regularly performed EMS tasks completed the survey. Three regression analyses were carried out, utilizing the three ProQOL 5 subscales as the dependent variables. The Perceived Coworker Support survey, Survey of Perceived Organizational Support, the Brief Resilience Survey and questions regarding debriefing practices were included.

Findings

Both organizational support and psychological resilience were found to be related to higher CS as well as lower burnout and STS. Coworker support was associated with higher CS. Informal debriefing was associated with higher CS and lower burnout. Several individual factors were also statistically significant, specifically education with CS, being a volunteer and race with burnout, and working part time or volunteering with STS.

Research limitations/implications

There are limitations due to the nature of cross-sectional survey design and due to the sample size. The varying circumstances which EMS personnel work also hinders generalizability.

Originality/value

This study displays statistical relationships between factors which EMS agencies could use to increase employee job satisfaction and potentially reduce turnover.

Abstract

Purpose

The purpose of this paper is to determine a baseline level of the Professional Quality of Life (ProQOL 5) in emergency dispatchers in the state of Florida, as well as to examine the how it is associated with psychological resilience, perceived coworker support, different types of debriefing, and perceived organizational support.

Design/methodology/approach

This was done through a cross-sectional administration of surveys to emergency telecommunicators and dispatchers in the state of Florida.

Findings

In total, 186 surveys were completed by active emergency dispatch personnel across the state of Florida. The study found that psychological resilience, education, and perceived organizational support were statistically related to professional quality of life in Florida Dispatchers.

Research limitations/implications

There are limitations due to the nature of cross-sectional survey design and due to the sample size. There are also possible issues with the accuracy of self-reported survey answers. The lack of participation from all agencies also hinders generalizability.

Practical implications

This study serves as a reference point for a very under studied emergency service population. There are also implications that psychological resilience development in dispatch personnel would assist in multiple aspects of their professional quality of life.

Originality/value

This is the first study to use the ProQOL 5 on dispatch personnel in Florida. It also displays statistical relationships between factors which dispatch agencies could use to increase employee job satisfaction and potentially reduce turnover.

Abstract

Purpose

The purpose of this paper is to investigate the relationship between ownership type and population health initiatives adopted by hospitals using the 2015 American Hospital Association data.

Design/methodology/approach

Hospitals of various sizes, ownership structures and geographic locations are represented in the survey. The outcome variables of interest include measures of hospital population health activities.

Findings

Findings indicate that nonprofit hospitals are most likely to express commitment to population health and participate in population health activities, with for-profit hospitals being least likely. Implications for policy and practice are discussed.

Research limitations/implications

This study demonstrates that discrepancies in population health approaches exist across ownership status – particularly, nonprofit hospitals appear to be the most likely to be involved in population health efforts.

Practical implications

As we continue to push for population health management in the hospital setting, grappling with the definition and purpose of population health management will be essential.

Social implications

Overall, these results suggest that nonprofit hospitals are more likely to be implementing population health efforts than for-profit or government-owned hospitals.

Originality/value

Although there are several studies on population health in hospitals, this study is the first to investigate the relationship between ownership type and population health initiatives adopted by hospitals.

Abstract

Purpose

The purpose of this study is to provide a new convolutional neural network (CNN) model with multi-scale feature extractor to segment and recognize wear particles in complex ferrograph images, especially fatigue and severe sliding wear particles, which are similar in morphology while different in wear mechanism.

Design/methodology/approach

A CNN model named DWear is proposed to semantically segment fatigue, severe sliding particles and four other types of particles, that is, chain, spherical, cutting and oxide particles, which unifies segmentation and recognition together. DWear is constructed using four modules, namely, encoder, densely connected atrous spatial pyramid pooling, decoder and fully connected conditional random field. Different from the architectures of ordinary semantic segmentation CNN models, a multi-scale feature extractor using cascade connections and a coprime atrous rate group is incorporated into the DWear model to obtain multi-scale receptive fields and better extract features of wear particles. Moreover, fully connected conditional random field module is adopted for post-processing to smooth coarse prediction and obtain finer results.

Findings

DWear is trained and verified on the ferrograph image data set, and experimental results show that the final Mean Pixel Accuracy is 95.6% and the Mean Intersection over Union is 92.2%, which means that the recognition and segmentation accuracy is higher than those of previous works.

Originality/value

DWear provides a promising approach for wear particle analysis and can be further developed in equipment condition monitoring applications.

Abstract

Purpose

The purpose of this paper is using a model-free reinforcement learning (RL) algorithm to optimize manipulability which can overcome difficulties of dilemmas of matrix inversion, complicated formula transformation and expensive calculation time.

Design/methodology/approach

Manipulability optimization is an effective way to solve the singularity problem arising in manipulator control. Some control schemes are proposed to optimize the manipulability during trajectory tracking, but they involve the dilemmas of matrix inversion, complicated formula transformation and expensive calculation time.

Findings

The redundant manipulator trained by RL can adjust its configuration in real-time to optimize the manipulability in an inverse-free manner while tracking the desired trajectory. Computer simulations and physics experiments demonstrate that compared with the existing methods, the average manipulability is increased by 58.9%, and the calculation time is reduced to 17.9%. Therefore, the proposed method effectively optimizes the manipulability, and the calculation time is significantly shortened.

Originality/value

To the best of the authors’ knowledge, this is the first method to optimize manipulability using RL during trajectory tracking. The authors compare their approach to existing singularity avoidance and manipulability maximization techniques, and prove that their method has better optimization effects and less computing time.

Abstract

Purpose

The digital economy has become a key force supporting the high-quality development of tourism. This paper discusses the coupling coordination relationship and spatiotemporal evolution path of digital economy and tourism in China's provinces.

Design/methodology/approach

This paper uses the entropy method to measure the development level of digital economy and tourism, and establishes coupling coordination model and spatial autocorrelation model to study the interaction between the two industries.

Findings

Results show that the development levels of the two industries are rising, which spatially show a progressively decreasing pattern of east-middle-northeast-west. The coupling coordination degrees of the two industries have increased steadily, but the overall level is still near maladjusted. Spatially, the positive correlation is increasing, but the incongruity of spatial agglomeration is still significant. The coupling coordination evolution path in the provinces shows differentiated characteristics. The migration path is mainly concentrated in Zones I and II. The eastern region has an obvious trend of extending to Zone III, where the tourism industry was the most affected by the pandemic.

Practical implications

The study helps clarify the industrial coupling and coordination relationship in various regions and formulate regional tourism digital transformation strategies to promote the high-quality development of China's tourism industry.

Originality/value

This paper enriches the research on the relationship between digital economy and tourism from the perspective of industrial integration. The development commonality of China's tourism digital transformation summarized provides theoretical reference and demonstration for the coordinated development of China's tourism.

Abstract

Purpose

Detection of hidden defects of aluminum alloy plate with damping coating is a challenging problem. At present, only a few non-destructive testing methods exist to address this engineering problem. Without the restriction of skin effect, remote field eddy current (RFEC) overcomes the interference caused by the damping coating. The RFEC, which has potential advantages for detecting the hidden defects of aluminum plate with damping coating, can penetrate the metal plate to detect buried depth defects. This study aims to test how thick the RFEC sensor can penetrate the metal plate to detect the buried defects.

Design/methodology/approach

The magnetic field distribution characteristics are analyzed, the magnetic field intensity distribution is calculated, and the structure and parameters of the coil, magnetic circuit and shielding damping are determined through the two- and three-dimensional finite element simulation methods. Optimal excitation frequency is obtained, and the distance between the excitation coil and detection coil is determined by analyzing the relationship between excitation frequency and remote field points.

Findings

Simulation and experimental results verify the feasibility of applying the RFEC detection technology in detecting the hidden defects of aluminum alloy plate with damping coating.

Originality/value

In this paper, the RFEC testing model of hidden defects in aluminum plate sample with damping coating is established by using the finite element method.

Abstract

Purpose

With the analysis of the causes of corruption, this study aims to investigate specific anti-corruption measures that can be implemented to reform the political system and the social climate of China.

Design/methodology/approach

This study examines 97 severe corruption cases of high-ranking officials in China, which occurred between 2012 and 2015. As this insinuates that both institutional and social corruption are major problems in China, the analysis delves into multiple facts of corruption, including different types, four primary underlying causes, and suggestions regarding the implementation of three significant governmental shifts that focus on investigation, prevention tactics and legal regulations.

Findings

China’s corruption is not only individual-based but also it has developed into institutional corruption and social corruption. Besides human nature and instinct, the causes of corruption can be organised into four categories, namely, social customs, social transitions, institutional designs and institutional operations. For the removed high-ranking officials, the formation of interest chains was an important underlying cause behind their corruption.

Originality/value

This study makes a significant contribution to the literature because this study provides a well-rounded approach to a complex issue by highlighting the significance of democracy and the rule of law as ways to regulate human behaviour to combat future corruption.

Abstract

Purpose

The purpose of this study is to further explore the effects of customer participation (CP) and service personal values (SPVs) on cruise customer satisfaction (CS) and customer loyalty (CL) by applying the empirical research approach.

Design/methodology/approach

A self-administered questionnaire was prepared and used to collect data. Exploratory factor analysis and structural equation modeling analysis was used to test the proposed model and hypotheses.

Findings

The empirical results indicate that CP positively influences SPVs, CS and CL. SPVs have a significant and positive impact on CS as well. Moreover, the study also finds that collectivism has a strong positive effect on CP. Price sensitivity negatively moderates the relationship among CP, CPV, CS and CL.

Research limitations/implications

The generalizability of the current study findings should be considered or scrutinized in light of the fact that limited samples and cross-sectional data were used. This limitation positions the findings as a continuation of the developing path toward a better understanding of customer behavior rather than a definitive conclusion.

Practical implications

The study results show that CP has a positive direct effect on SPVs, CS and CL. Even though many researchers have verified the importance and function of CP, there is a lack of literature, which assesses the influence of CP in a cruise industry context. By focusing on this gap, this research makes it feasible to empirically analyze the different effects of CP in relation to SPVs, CS and CL in Chinese cruise preferences.

Social implications

The study results suggest that CP is a new predictor of CS and CL in the cruise industry. Thus, creating a positive experience through participation is crucial. As customers are co-producers, it is beneficial for the cruise companies to raise labor productivity and reduce cost by guiding and stimulating them to take part in the service-producing process.

Originality/value

Based on the perspective of service-dominant logic, the purpose of this study is to shed light on the formation process of loyalty behavior of Chinese cruise tourists. The empirical results indicate that CP positively influences SPVs, CS and CL. SPVs have a significant and positive impact on CS as well. Moreover, the study also finds that collectivism has a strong positive effect on CP. Price sensitivity negatively moderates the relationship among CP, CPV, CS and CL.

La lealtad de los clientes chinos de cruceros: el impacto de la participación de los clientes y los valores personales del servicio

Objetivo

El propósito de este estudio es explorar, en profundidad, los efectos de la participación del cliente (CP) y los valores personales del servicio (SPV) en la satisfacción del cliente de cruceros (CS) y la lealtad del cliente (CL) aplicando el enfoque de la investigación empírica.

Diseño/metodología/enfoque

La obtención de datos se realizó a través de un cuestionario autoadministrado. El modelo y las hipótesis propuestas fueron contrastados a través del análisis factorial exploratorio (EFA) y el análisis de ecuaciones estructurales (SEM).

Resultados

Los resultados empíricos indican que la CP influye positivamente en los SPV, CS y CL. Los SPVs también tienen un impacto significativo y positivo en la CS. Además, el estudio también encuentra que el colectivismo tiene un fuerte efecto positivo en el CP. La sensibilidad al precio modera negativamente la relación entre CP, CPV, CS y CL.

Limitaciones/implicaciones de la investigación

La posibilidad de generalizar las conclusiones del presente estudio debe considerarse teniendo en cuenta que se utilizaron muestras limitadas y datos transversales. Esta limitación hace que los hallazgos avancen en la senda para una mejor comprensión del comportamiento del cliente y no sean una conclusión definitiva.

Implicaciones prácticas

Los resultados del estudio muestran que el CP tiene un efecto directo positivo en las SPVs, CS y CL. Aunque muchos investigadores han verificado la importancia y la función de la CP, falta literatura que evalúe la influencia de la CP en el contexto del sector de los cruceros. Al centrarse en esta carencia, esta investigación permite analizar empíricamente los diferentes efectos de la CP en relación con las SPVs, CS y CL en las preferencias de los cruceristas chinos.

Implicaciones sociales

Los resultados del estudio sugieren que la CP es un nuevo predictor de la CS y la CL en el sector de los cruceros. Por tanto, crear una experiencia positiva a través de la participación es crucial. Dado que los clientes son coproductores, es beneficioso para las compañías de cruceros aumentar la productividad laboral y reducir los costes guiándolos y estimulándolos a participar en el proceso de producción del servicio.

Originalidad/interés

Basado en la perspectiva de la lógica dominante del servicio, el propósito de este estudio es arrojar luz sobre el proceso de formación de la lealtad de los turistas chinos de cruceros. Los resultados empíricos indican que la participación del cliente (CP) influye positivamente en los valores personales del servicio (SPV), la satisfacción del cliente (CS) y la lealtad del cliente (CL). Los SPVs también tienen un impacto significativo y positivo en la CS. Además, el estudio también encuentra que el colectivismo tiene un fuerte efecto positivo en el CP. La sensibilidad al precio modera negativamente la relación entre CP, CPV, CS y CL.
