Abstract

THE Society of Automotive Engineers' paper, upon which this article is based, followed very closely along the lines of an article entitled ‘Composite Power Plant System for V/S.T.O.L. Aircraft’ published in the December, 1962, issue of AIRCRAFT ENGINEERING [see Ref. (4)]—although the latter paper concentrated upon a description of the RB. 162 and the use of lightweight lift engines for a V/S.T.O.L. low‐level strike fighter. The S.A.E. paper has therefore been slightly condensed here, to avoid unnecessary duplication and a number of illustrations have been omitted. Throughout this paper there are references to the advantages of a multi‐engined aircraft for the V/S.T.O.L. fighter application in preference to the single‐engined type. These passages must be read in the light of the recent statement to the effect that Rolls‐Royce have submitted to the Ministry of Aviation design proposals for a version of the Hawker PA 154 V.T.O.L. aircraft powered by two lift/thrust engines based upon the Spey by‐pass engine. These two lift (thrust engines would replace the single Bristol Siddeley BS.100 vectored thrust engine which is believed to have a thrust (with plenum chamber burning) of about 30,000 lb. Apart from the more obvious advantage of having two engines, i.e. safety, and the ability of the aircraft to complete the mission as a conventional aircraft if one engine fails, there is also the additional and attractive proposition that the Rolls‐Royce Spey engine is already in quantity production for a number of civil and military aircraft and could presumably be readily adapted to a lift/thrust configuration with front nozzle incorporating plenum chamber burning and rear nozzle. Finally, the reader is recommended to study in full the articles referred to in Refs. (2), (3), (4) and (5), in addition to this paper, since these provide a comprehensive survey of the jet lift field and in particular the application of jet lift to V/S.T.O.L. fighters. The six references listed on this page did not, of course, form part of the original S.A.E. paper—Editor.

Abstract

Purpose

The purpose of this paper is to examine the role of safety participation as a mediator in the relationship between the six facets of safety management practices (i.e. management commitment, safety training, worker’s involvement, safety communication and feedback, safety rules and procedures, and safety promotion policies) and safety compliance.

Design/methodology/approach

A survey of 74 employees of small and medium enterprises (SMEs) in the northern region of Peninsular Malaysia was carried out. Self-reported measures were used to obtain data on workplace safety dimensions and safety behavior. The partial least square structural model analysis was used to ascertain the proposed relationships.

Findings

The present study found that only three dimensions of safety management practices (management commitment, safety training, and safety rules and procedures) were significantly related to safety compliance. Of these, safety participation mediated the link between management commitment and safety training and safety compliance.

Research limitations/implications

The small sample size may limit the generalizability of the findings. Second, the correlational nature of the study did not permit causation to be implied. However, despite these limitations, while safety performance can be theorized to trigger the establishment of safety management practices, such theoretical perspective tends to connote reactivity rather than proactivity of the decision-making process.

Practical implications

The study highlights the role of the voluntary behavior of employees in promoting a safe work environment. Business owners are recommended to provide safety training in which the employees are stressed on their crucial role in safety and use this knowledge to educate and convince their co-workers to work safely.

Originality/value

Literature indicates the lack of studies on safety research in SMEs. Furthermore, such studies are justified because SMEs are likely to have more risks of occupational accidents and injuries. More importantly, this research highlights the importance of the voluntary behaviors of employees (i.e. safety participation) in promoting a safe work environment. As SMEs tend to have limited resources to implement a comprehensive OSH management system, using the employees as the safety agents at work can be an effective way toward accomplishing safety performance.

Abstract

This study proposes targeted modernization of the Department of Defense (DoD's) Joint Forces Ammunition Logistics information system by implementing the optimized innovative information technology open architecture design and integrating Radio Frequency Identification Device data technologies and real-time optimization and control mechanisms as the critical technology components of the solution. The innovative information technology, which pursues the focused logistics, will be deployed in 36 months at the estimated cost of $568 million in constant dollars. We estimate that the Systems, Applications, Products (SAP)-based enterprise integration solution that the Army currently pursues will cost another $1.5 billion through the year 2014; however, it is unlikely to deliver the intended technical capabilities.

Abstract

Purpose

Evidence is lacking as to the superiority of dual-focused versus single-focused approaches in treating depression and alcohol use comorbidity. Different people may also value the different features of treatment options differently, necessitating a decision-support tool. This study aims to test the acceptability, feasibility, safety and potential usefulness of the Alcohol and Depression Decision-Aid for Psychological Treatments (ADDAPT).

Design/methodology/approach

ADDAPT was developed according to International Patient Decision-Aid Standards and in consultation with potential end users. Adults with depression and alcohol use comorbidity, who were considering/recently considered psychological treatments, were recruited via online advertisements. After clicking on the study URL, participants accessed the ADDAPT e-book and completed validated and purpose-designed questionnaires.

Findings

Of the 24 participants, most would recommend ADDAPT to others (79.2% agree) and endorsed it as easy-to-use (75%), useful in decision-making (79.2%), presenting balanced (87.5%), up-to-date (91.7%), easy-to-understand (79.2%) and trustworthy information (83.3%), which did not provoke anxiety (i.e. safety; 75%). Post-use, participants felt well prepared to decide on treatment (M = 3.48/5) and demonstrated good treatment knowledge (M = 65.83%). All but one participant indicated a treatment choice supported by best available evidence, and decisional conflict scores except for the uncertainty subscale were below the threshold for decisional delay (all M < 37.5/100).

Originality/value

ADDAPT is the first decision-aid of its kind, with pilot findings supporting its acceptability, feasibility, safety and potential usefulness for improving decision-making quality among people considering psychological treatment options for depression and alcohol use comorbidity.

Abstract

Purpose

The purpose of this paper is to present a hierarchy decision model for assessing the priority of safety management elements in manufacturing enterprises with reference to three major industries (i.e. textile and clothing, electronics, and printing and publishing) in Hong Kong. The identification of core decision criteria and safety management elements were addressed with respect to the effective implementation of safety management systems (SMS) in manufacturing enterprises.

Design/methodology/approach

Empirical data were acquired via a conduct of personal interviews with evaluators (i.e. safety personnel, experts and professionals) in industry. Using the analytic hierarchy process (AHP) methodology, a list of seven decision criteria and 13 safety management elements were identified and their relative importance were evaluated.

Findings

It was found that the top three criteria for SMS implementation were “client requirement” “insurance company requirement” and “employee requirement”. Both “safety organisation” and “safety policy” were the most important safe management elements. Besides, evaluators put greater concerns on “safe person” elements than “safe place” elements. Incorporating the AHP findings, a self‐regulatory approach to implementing safety management elements was proposed.

Research limitations/implications

The hierarchy decision model would enable manufacturing enterprises to focus their resources on the critical elements at a time, to improve the effectiveness of SMS implementation. Future study could validate the applicability of the model and the self‐regulatory approach in large enterprises and small to medium‐sized enterprises, separately and collectively.

Practical implications

Using the AHP methodology, safety personnel could evaluate the relative importance of decision criteria and safety management elements with respect to the corporate goals, resources and constraints of their respective organisations.

Originality/value

The hierarchy decision model presented would enable manufacturing enterprises to determine the relative importance of decision criteria and safety management elements and to establish viable strategies for SMS implementation.

Abstract

Purpose

This paper examines how nurses differentially respond, both emotionally and behaviorally, to incivility from coworkers (i.e. other healthcare staff) and from their patients. Specifically, the authors explore how coworker and patient incivility distinctly influence the extent to which nurses engage in emotional labor, which in turn, may impact nurses' safety performance. The authors further examine how nurses' hostile attribution biases exacerbate and mitigate these effects.

Design/methodology/approach

A three-week longitudinal study was conducted with 187 nurses in which they reported their experiences with incivility, surface and deep acting, hostile attribution biases and safety performance (i.e. safety compliance and participation).

Findings

Patient incivility led to more surface acting across all nurses. Further, the effects of coworker incivility on emotional labor strategies were conditional on nurses' hostile attribution biases (HAB). Specifically, coworker incivility led to more surface acting among nurses higher on HAB, and coworker incivility led to less deep acting among those lower on HAB. Finally, surface acting was associated with reduced safety participation, and deep acting was associated with greater safety compliance and safety participation.

Originality/value

The nursing context allowed the current research to extend understanding about how incivility affects an unexplored outcome—safety performance. The current research also offers a rare examination of the effects of incivility from multiple sources (i.e. coworkers and patients) and demonstrates the different processes through which incivility from these different sources impacts nurses' ability to perform safely.

Abstract

Purpose

The purpose of this paper is to explore cultural tourism investment and resident quality of life in the Midwestern city of Indianapolis, Indiana. It is important to understand from a cultural tourism perspective how further attempts to grow and invest in tourism will affect resident perception of quality of life and future cultural tourism investment.

Design/methodology/approach

To achieve this goal, data from the 2012 Indianapolis Quality of Life survey was statistically analyzed to specifically examine how residents’ perceived quality of life affects cultural tourism investment. This allows for the study of what city-service attributes (i.e. safety, attractions, transportation, etc.) identify as potential indicators of whether residents’ perception of quality of life affects cultural tourism investment and if there were any correlations between demographic factors of age, gender, ethnicity, and household income with the perception that investing in cultural events and attractions for tourists is good for residents.

Findings

Results indicated that several key city-service attributes identify as potential indicators of whether residents’ perception of quality of life in Indianapolis affects residents’ perceptions that investing in cultural tourism for tourists is good for residents. Furthermore, excluding perceptions of cultural tourism investment, several key city-service attributes identified as potential indicators of residents’ perception of quality of life in Indianapolis. Finally, results indicated that demographic factors of gender, age, ethnicity, and income were not significant when it came to affecting the perception that investing in cultural events and attractions for tourists is good for residents.

Research limitations/implications

The findings of this study have unique academic and applied implications in the continued study of tourism in Indianapolis, Indiana. This study provided research related to the study of quality of life in Indianapolis and reported statistics for the 2012 Indianapolis Quality of Life survey. The data and statistical analysis reported in this study will serve as valuable information for future endeavors concerning cultural tourism and quality of life in Indianapolis. The identification of city-service attributes that significantly impact resident perception of quality of life and city-service attributes that, in conjunction with resident perception of quality of life, affect how residents perceive cultural tourism investments is important information that can be utilized by future researchers, tourism planners, and policymakers in Indianapolis. The analysis revealed what city-service attributes are important to residents of Indianapolis and demographic factors that affect resident perception of quality of life. The continued examination of these city-service attributes may help to identify areas of public service that need to be improved.

Practical implications

This study demonstrates that resident level of awareness pertaining to the benefits of cultural tourism investment are relatively low. Tourism planners, officials, and researchers can utilize this knowledge to better facilitate methods to gain resident support for cultural tourism investment and development. In addition, this research can be utilized to better understand the needs of residents and how tourism and various city-services impact their quality of life. If cultural tourism planners and other tourism officials better understand methods to gain resident support for cultural tourism investment then they can maximize economic and cultural tourism gains for the city.

Originality/value

This case study specifically focussed on cultural tourism to better present data regarding this issue; however, the authors believe future studies that examine both cultural and sports tourism could be beneficial. Aspects such as city-services and resident perception of quality of life could be examined from both cultural and sports tourism perspectives. This approach could produce beneficial results regarding cultural and sports tourism investment and potentially highlight demographic characteristics unique to cultural tourism and sports tourism supporters in the city of Indianapolis.

Abstract

Purpose

This paper aims to investigate how perceived working conditions affect employee performance, including safety compliance and task performance, through employee well-being (i.e. job satisfaction) in the context of the coal mining sector in China.

Design/methodology/approach

This paper uses the job demands-resources model to test the relationships between working conditions, including job demands (work pressure as a challenge demand and perceived risks and hazards in the workplace and ineffectiveness of the safety system as hindrance demands), job resources (interpersonal harmony), job satisfaction and performance. This study adopts a two-wave design with a three-month lag to reduce possible common method bias.

Findings

Employees who experienced high level of challenge demands, e.g. time pressure workload, reported higher levels of task performance, and this positive relationship seemed to be robust. There is a direct effect of perceived ineffectiveness of the safety system on task performance, while the relationship between perceived risks and hazards and task performance was fully mediated by job satisfaction. Challenge demands, i.e. work pressure, did not impact much on employees’ well-being, and thus job satisfaction did not mediate the relationship between work pressure and performance. Perceived ineffectiveness of the safety system was negatively associated with safety compliance. This result is not surprising since a lack of effective safety system reflects management’s ignorance of workplace safety, which demotivates employees to enact safe behaviors. In contrast, the presence and implementation of an effective safety system would be interpreted by employees as management exhibiting a high level of commitment. Work pressure was positively not negatively related to safety compliance. One possible explanation for this finding is that the effects of work pressure on safety compliance behaviors might be dependent on contextual factors such as safety climate. Interpersonal harmony moderated the relationships between work pressure and employee performance (both safety compliance and task performance) and the relationship between perceived risks and hazards and task performance, but the role of interpersonal harmony appeared more complex. There was no significant correlation between challenging job demands and individual employee performance when there were higher levels of interpersonal harmony. The relationship between perceived risks and hazards, a hindrance job demand and task performance became positive as interpersonal harmony increased but negative as interpersonal harmony decreased.

Originality/value

This paper provides a robust integrative theoretical framework that better explains the various types of job demands and job resources in the working environment of coal mining sector in China and their relationships to employee performance. The findings also offer valuable guidance for managers trying to identify effective ways to enhance employee performance and safety in the workplace.

Abstract

While research on workplace safety spans across disciplines in medicine, public health, engineering, psychology, and business, research to date has not adopted a multilevel theoretical perspective that integrates theoretical issues and findings from various disciplines. In this chapter, we integrate research on workplace safety from a variety of disciplines and fields to develop a multilevel model of the processes that affect individual safety performance and safety and health outcomes. In doing so, we focus on cross-level linkages among national, organizational, and individual-level variables in relation to the exhibition of safe work behavior and occurrence of individual-level accidents, injuries, illnesses, and diseases. Our modeling of workplace safety is intended to fill a theoretical gap in our understanding of how the multitude of individual differences and situational factors interrelate across time to influence individual level safety behaviors and the consequences of these actions, and to encourage research to expand the limits of our knowledge.
