Abstract

Purpose

WIth limited research on the effects of variable message sign (VMS) message content and verbiage on revealed driver behavior, this study aims to investigate how different verbiage of crash-related messages are related to the diversion rate.

Design/methodology/approach

Using ordered logit models, the associations of message verbiage with diversion rates during crash incidents were assessed using five years of VMS message history within a section of I-15 in the state of Utah.

Findings

A significant impact of message verbiage on the diversion rate was observed. Based on the analysis results, the crash message verbiage with the highest diversion was found to be miles to crash + “prepare to stop,” followed by crash location + delay information, miles to crash + “use caution” + lane of the crash, etc. In addition, the diversion rate was found to be correlated to some roadway characteristics (e.g. occupancy in mainline, weather condition and light condition) along with the temporal variations.

Research limitations/implications

These findings could be used by transportation agencies (e.g. state department of transportation [DOTs]) to make informed decisions about choosing the message verbiage during future crash incidents. This study also revealed that higher diversion rates are associated with a shorter distance between the crash location and VMS device location, recommending increasing the number of VMS devices, particularly in crash-prone areas.

Abstract

Purpose

The purpose of this paper is to improve the health and criminal justice outcomes for people who come into contact with the criminal justice system. People with learning disabilities (LD) are particularly vulnerable to health and social inequalities within the criminal justice system.

Design/methodology/approach

Using examples from practice, this paper discusses some of the challenges and achievements experienced by a LD nurse employed within a liaison and diversion service within the North-West of England.

Findings

Whilst the specific functions of liaison and diversion practitioners are detailed by National Health Service (NHS) England (2014), complexities in communication, multi-disciplinary working and role recognition affect the embedment of the role in practice.

Research limitations/implications

The implications for practice are identified and recommendations for further research made. These seek to evaluate the impact of liaison and diversion services from the perspectives of LD nurses within liaison and diversion services, people with LD, their families and the wider multi-disciplinary team.

Originality/value

NHS England (2015) are in the process of evaluating of liaison and diversion services. This paper adds to the evaluation by discussing the experiences of a LD nurse within a liaison and diversion service through the inclusion of activity data and illustrative examples.

Abstract

Purpose

The purpose of this study was to describe programs that aim at programs to divert people with a mental condition from the criminal justice system to mental health services are being initiated, but reporting is limited and fragmented. This study described programs that aim at diverting persons with mental health conditions out of criminal justice systems to community mental health services, with the intention to inform research and practice.

Design/methodology/approach

A scoping review was used to map and synthesise diversion programs. Ten online data bases were searched. Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews was used to direct the selection of sources. Research and evaluation publications and grey literature published from 2010 to 2021 in English language were included.

Findings

Eight distinct diversion programs were identified across 24 countries or territories covering five phases of the criminal justice process. Diversion programs included crisis intervention teams, the electronic linkage system, mobile crisis units, the criminal justice liaison program, problem-solving courts, the abstinence-based program, the community equivalence program and the forensic assertive community treatment program. Although distinct programs have the potential to form a system of diversion across the continuum of the criminal justice process, only two territories moved in that direction. Diversion programs reported overwhelmingly originated from high-income countries.

Practical implications

Stigma that labels people with mental health conditions as violent and dangerous need to be addressed. It is important to place diversion systems on national policy agendas and advocate for evidence-based interventions.

Originality/value

The study provides a blueprint on diversion systems to set a research agenda and develop a road map, tailored towards local contexts.

Abstract

Purpose

Waste diversion rate (WDR) is a key indicator of effective waste management and circular economy. However, it has not yet been widely used in the construction and demolition waste (C&DW) sector. This study aims to promote the application of WDR as an effective measure for waste management through the investigation of the current status of C&DW diversion in the Australian construction industry.

Design/methodology/approach

A mixed-method approach, which combines a desk study and a case study of 12 residential projects was used in this study. Data retrieved from the National Waste Database (NWD) were used for the descriptive analysis.

Findings

The analysis of the national waste data revealed that the national average WDR in Australia is 64%. WDR varies based on material types and across the states. The analysis facilitated the forecasting of the possible future trend of waste diversion in Australia. The studied projects from two states in Australia presented slightly different results. Most of the waste stream, except mixed waste, presented above 95% of WDR in each project.

Research limitations/implications

Although the studied projects showed a higher recycling rate, this study claims that achieving a higher rate of recovery by diverting the waste could not be assured unless accurate estimation is carried out with reliable and verifiable data. Lack of reliable data is considered as the limitation of this study. While the scope of descriptive analysis of waste generation and diversion covers the whole country, the case study analysis is limited to the states of New South Wales and Victoria.

Originality/value

The study highlights the significance of WDR in assessing the performance of effective waste management in the C&DW sector. WDR is a comprehensive measure that takes the output of the waste life cycle into account for benchmarking waste management. The results provide a critique of the current practices of waste management and the essence of the consistent, transparent and verifiable waste data to enable accurate WDR estimation in Australia. The outcome is useful for waste managers and policymakers in developing potential waste management strategies and C&DW specific legislation for building a more ecologically sustainable industry.

Abstract

Purpose

This study explores the determinants of police officer support for pre-arrest/booking deflection programs that divert people presenting with substance use and/or mental health disorder symptoms out of the criminal justice system and connect them to supportive services.

Design/methodology/approach

This study analyzes responses from 254 surveys fielded to police officers in Delaware. Questionnaires asked about views on leadership, approaches toward crime, training, occupational experience and officer’s personal characteristics. The study applies a new machine learning method called kernel-based regularized least squares (KRLS) for non-linearities and interactions among independent variables. Estimates from a KRLS model are compared with those from an ordinary least square regression (OLS) model.

Findings

Support for diversion is positively associated with leadership endorsing diversion and thinking of new ways to solve problems. Tough-on-crime attitudes diminish programmatic support. Tenure becomes less predictive of police attitudes in the KRLS model, suggesting interactions with other factors. The KRLS model explains a larger proportion of the variance in officer attitudes than the traditional OLS model.

Originality/value

The study demonstrates the usefulness of the KRLS method for practitioners and scholars seeking to illuminate patterns in police attitudes. It further underscores the importance of agency leadership in legitimizing deflection as a pathway to addressing behavioral health challenges in communities.

Abstract

Purpose

The purpose of this paper is to study the pipe-type electromagnetic induction heating device under power frequency condition.

Design/methodology/approach

To reduce eddy current loss and improve heating efficiency, the structure of a pipe-type power-frequency electromagnetic heating device was optimized. Based on the maximum load flow formula, a parallel excitation winding structure is designed, and the distribution of electromagnetic field under four different powers is analyzed by simulation. Four heating modes were proposed according to the structure of diversion ring, inner wall and outer wall. Two heating modes with better heating effect were obtained by comprehensively considering the factors such as magnetic field distribution, thermal power and energy consumption.

Findings

The double-wall structure of the pipe-type electromagnetic heating device can make the heat source distribution more uniform, and the use of power-frequency power supply can increase security, the installation of diversion ring can make the heating more sufficient and the heating efficiency of the two heating methods selected according to the structural performance is more than 90%.

Originality/value

In view of the medium or high frequency of pipe-type electromagnetic heating device, it is necessary to configure high power electronic frequency conversion drive system, and eddy current can only be produced on the tube wall, resulting in uneven distribution of heat sources. A pipe-type power-frequency electromagnetic heating device with double-wall structure was proposed.

Abstract

Purpose

The purpose of this paper is to investigate users’ continuous adoption behaviors on mobile game playing from the perspective of situational habit formation.

Design/methodology/approach

Based on the literature research, a continuous adoption model for situational mobile game is proposed. And the research model is assessed based on data gathered from a sample of 226 mobile game players by employing the structural equation model methodology.

Findings

The results show that situational cues represented by availability, perceived ease of use and diversion lead to repeated performance that can be represented by flow experience and satisfaction in the situational mobile game playing context. But only flow experience and diversion influence continuous usage directly. Additionally diversion, as a critical situational variable, not only indirectly affects continuous usage intention through flow experience, but also directly affects continuous usage intention for situational mobile game playing.

Originality/value

Mobile game adoption has been studied from different perspectives, but most research is based on the technology acceptance model. They could not explain the common fact that young people tend to be highly motivated by mobile games and can be regarded as pro-active mobile game players, but many people play mobile games only when they are bored and need a diversion. So this study attempts to illustrate the phenomena to fill the gaps.

Abstract

Purpose

The purpose of this paper is to examine the effects of a regional trade agreement among a group of small island developing states on trade creation and trade diversion.

Design/methodology/approach

An augmented gravity model and panel data are used to estimate the trade creation and trade diversion effects. The generalized method of moments technique is used to account for possible endogeneity. Country pair and time fixed effects are also included.

Findings

The regional trade agreement had a positive effect on intra-regional trade creation, but there was no significant diversion of imports from extra-regional trade partners.

Practical implications

Small developing economies can benefit from regional trade agreements (RTAs) among themselves. The trade diversion effects of such agreements are likely to be limited.

Originality/value

To the best of authors’ knowledge, this is the only paper which investigates the impact of RTAs among small island developing states.

Abstract

Purpose

An optimal control model is built considering the private sector's opportunistic effort diversion and reciprocal effort improvement, while a numerical study is conducted to draw some managerial implications.

Design/methodology/approach

In infrastructure PPP projects, private sectors may opportunistically divert part of their effort from the current projects to other projects to allocate their limited human resources. Nevertheless, this effort diversion can be inhibited by dynamic incentives since the private sectors reciprocally exert greater effort into the current projects when receiving the dynamic incentives. This article investigates how the government specifies the output standard that the private sector should meet and offers dynamic incentives to mitigate the private sector's opportunistic effort diversion.

Findings

The output standard for the private sector to acquire the dynamic incentives should be specified as the output level corresponding to the private sector's optimal long-run stationary equilibrium (OLSE) effort level, which decreases with its reciprocal preference level but increases with its effort-diverting level. The optimal dynamic incentives comprise an initial incentive and a periodic OLSE incentive, which declines with the reciprocal preference level but improves with the effort-diverting level. Besides, the numerical study reveals that the government should distinguish whether the bidders have high effort-diverting levels and, if so, should focus on their reciprocal preference levels and decline the bidders with low reciprocal preference to avoid utility loss.

Originality/value

This article provides a theoretical model combining opportunistic behavior with reciprocal preference through an optimal control lens, thus embedding the problem of incentive design into a broader socioeconomic framework.

Abstract

Provision of comprehensive diversion services for the mentally disordered who come into conflict with the law offers benefits for patients and all those involved in the process, including the police, crown prosecution service and other agencies. It gives access to the most appropriate disposal for this vulnerable group. This case study of a man who had multiple contacts with the diversion services in Birmingham illustrates the particular difficulties associated with diversion from custody for mentally disordered individuals, particularly where there are multiple problem areas. Examination of the case suggests that in spite of inter‐agency commitment to the philosophy of diversion, in some instances a period spent in custody is unavoidable.
