Abstract

Purpose

The purpose of this paper is to present the method of lines (MOL) solution of the stimulated Brillouin scattering (SBS) equations (a system of three first-order hyperbolic partial differential equations (PDEs)), describing the three-wave interaction resulting from a coupling between light and acoustic waves. The system has complex numbers and boundary values.

Design/methodology/approach

System of three first-order hyperbolic PDEs are first transformed and then spatially discretized. Superbee flux limiter is proposed to offset numerical damping and dispersion, brought on by the low order approximation of spatial derivatives in the PDEs. In order to increase computational efficiency, the structured structure of the PDE Jacobian matrix is identified and a sparse integration algorithm option of the ordinary differential equation (ODE) solvers is used. The flux limiter based on higher order approximations eliminates numerical oscillation. Examples are presented, and the performance of the Matlab ODE solvers is evaluated by comparison.

Findings

This type of solution provides a rapid means of investigating SBS as a tool in fiber optic sensing.

Originality/value

To the best of the authors' knowledge, MOL solution is proposed for the first time for the modeling of three-wave interaction in a SBS-based fiber optic sensor.

Abstract

This synthesis covers academic research on the use of valuation, tax, information technology (IT), and forensic specialists on audit engagements. The importance and role of specialists on audit engagements have recently increased, and specialist use has garnered significant attention from regulators and academics. Given the PCAOB’s (2017b) recent proposal to revise auditing standards regarding specialists’ involvement, it is important to review the specialist literature as a whole. By integrating research across these four domains, I identify commonalities and differences related to: (1) factors associated with the use of specialists on audit engagements (including the nature, timing, and extent of use); (2) factors impacting auditors’ interactions with specialists (including specialists contracted by the auditor or management); and (3) outcomes associated with the use of specialists. This integrated analysis of the specialist literatures shows variation in the use of specialists, and various factors affecting both if and how they are involved and whether auditors use specialists internal or external to the audit firm. Additionally, research has sometimes (but not always) linked specialist involvement to higher audit quality. The commonalities and areas of variation identified are informative to audit research and practice, particularly as regulators and audit firms look to improve the quality of audits using specialists. Throughout the synthesis, I also provide a number of directions for future research.

Abstract

Purpose

To provide a summary of the principles, theories and basic components of a recently developed brief integrated motivational intervention (BIMI) for working with individuals experience co-ccurring severe mental health and substance use problems in inpatient settings, including the outcomes of a feasiblity randomised controlled trial (RCT). There are greater financial costs and a negative impact on functioning associated with psychiatric admissions for people who experience co-occurring severe mental heath and substance misuse problems. In addition, their engagement in treatment is often problematic.

Design/methodology/approach

The BIMI described was evaluated via a feasibility RCT that assessed whether the opportunity to discuss use of substances whilst on an inpatient ward represented an opportunity to engage inpatients in thinking about their use and the impact it has on their mental health.

Findings

The BIMI is delivered in short burst sessions of 15-30 minutes over a two-week period adopting a simple 3-step approach that can be delivered by routine ward staff. It incorporates an assessment of substance use, mental health and motivation followed by personalised feedback, a focus on increasing awareness of the impact on mental health and development of goals and a change plan. The intervention has been shown to lead to higher levels of engagement in clients exploration of substance use and the impact on mental health. Findings suggest both staff and inpatients found the intervention feasible and acceptable.

Originality/value

Routine ward staff were trained to deliver a brief intervention to inpatients during an acute hospital admission.

Abstract

Constructive deviance has received increasing attention across the last 20 years. However, because the distinction between constructive and traditional forms of deviance (i.e., destructive) is based on the intent behind the behaviors, it can be difficult to determine which acts are constructive. As an umbrella construct consisting of several forms of deviant acts (e.g., whistle-blowing, employee voice, necessary evils), research into constructive deviance has largely remained focused on the individual behaviors to date. While advancements have been made, this focus has limited the consideration of an overarching understanding of constructive deviance in the workplace. Further, constructs like constructive deviance that straddle the bounds between beneficial and detrimental necessitate the exploration into their antecedents as determined by the employees (i.e., apples), their environments (e.g., barrels), or some combination of the two. The author seeks to advance the research in constructive deviance by proposing a testable model. In which, the author develops an interactionist perspective of the antecedents to reposition constructive deviance as the acts of good employees in restrictive or negative environments. In doing so, the author considers how various aspects of individuals, their organizational environments, and the influence of their leaders interact. The author then develops a multi-stakeholder approach to the outcomes of constructive deviance to consider how the various parties (i.e., organization, coworkers, customers) are expected to respond and how these responses impact the more distal outcomes as well as the likelihood of engaging in future constructive deviance.

This paper aimed to examine the role of social factors and individual factors on alcohol drinking in a licensed premise.

Abstract

Purpose

This paper aimed to examine the role of social factors and individual factors on alcohol drinking in a licensed premise.

Design/methodology/approach

An unobtrusive covert systematic observational study of 632 licensed premise patrons was conducted during May 2015.

Findings

Convergence between genders was observed with females drinking as much and as long as males; 57.9 per cent of patrons drank two and more servings, exceeding daily recommended amounts. Social factors such as group size are more influential on drinking than individual factors such as gender and smoking status. Serving practices such as straws and buying drinks in rounds influence the quantity of alcohol consumed.

Research limitations/implications

The study focussed on one licensed premise. Replication of the method outlined in the current study in different licensed venues, states and countries will permit the role of policy, drinking environments and drinking cultures to be understood.

Practical implications

Drinking patterns of both genders are converging. Thus, intervention efforts should target both genders.

Originality/value

This paper contributes a structured observation protocol that extends our understanding of alcohol drinking beyond quantity by incorporating observation of duration of consumption for each serve, permitting identification of social and environmental factors that can be used to lower licensed premise alcohol drinking.

Abstract

SO much controversy has raged around the subject of newsrooms in the past two years, that librarians are, as a rule, utterly tired of it, and the appearance of still another article upon the subject is not calculated to tone down the general spirit of vexation. It requires no little courage to appear in the arena in this year of Grace, openly championing those departments of our institutions which were originally intended to convey the news of the day in the broadest manner.
