On a combined theory of pay level satisfaction

For decades, research on pay level satisfaction has focused on two theories and one approach: the direct link theory, the discrepancy theory, and the no‐difference‐scores approach. However, there are still unsolved puzzles facing pay level satisfaction research. We develop a combined theory to consider the impact of the interaction of reported pay and pay discrepancy. With this newly developed theory, we expect that (a) both reported pay and pay discrepancy have main effects on pay level satisfaction; (b) reported pay and pay discrepancy also interact with each other, in that the effect of pay discrepancy on pay level satisfaction decreases as pay level increases; (c) equitable payment is more related to pay level dissatisfaction when pay level is low; and (d) overpayment in general is related to pay level satisfaction, not dissatisfaction. An empirical study (N = 481) using four types of comparison standards was conducted, and the results supported our predictions. The findings of our study have important implications for both academic research and management practice.     

Financial incentives,professional values and performance: A study of pay‐for‐performance in a professional organization

We investigated the effect of financial incentives on performance in a professional organization. Whereas agency theory treats tangible rewards such as money as a potentially powerful motivator for improving performance, the professional control perspective posits that the motivational effects of financial incentives will depend on the intended recipients attitudes toward the incentives relative to their professional values. The study setting was a large network of physician practices that adopted a financial incentive program to improve physician performance in the management of diabetic patients. Consistent with agency theory, performance did improve following the introduction of the incentive. However, consistent with the professional control perspective, physicians' psychologically based attitudes toward the incentive program regarding its impact on their own work autonomy and the importance of the performance goals moderated the effect of the incentive on performance. Study findings indicate that agency theory and professional control are complementary theoretical perspectives for understanding how professionals will respond to the imposition of performance‐related financial incentives. In terms of practice, pay‐for‐performance programs aimed at professional organizations should be designed to take into account the values and goals of an organization's professionals to maximize the effect of financial incentives on performance.

Heavy gas dispersion by water spray curtains: A research methodology

The mitigation of the consequences of accidental releases of dangerous toxic and/or flammable cloud is a serious concern in the petro-chemical and gas industries. Nowadays, the water-curtain is recognized as a useful technique to mitigate a heavy gas cloud. The paper presents a research methodology, which has been established and undertaken to quantify the forced dispersion factor provided by a water-curtain with respect to its configuration.

The method involves medium-scale field tests, Wind-Gallery tests and numerical simulations. These different approaches are discussed and exemplified by typical results emphasizing the observed concentration reduction due to the water-curtain.     

Experimental evidence for the effects of task repetitiveness on mental strain and objective work performance

People frequently have to work in high repetitive jobs. Previous research has focused exclusively on the effects of task repetitiveness on well‐being, while neglecting effects on work performance. In the present study, we aimed to fill this void by conducting two workplace simulations with experimental manipulations of task repetitiveness. Participants worked for about 5 hours at either a computer workstation, compiling computer hardware packages according to customer requests (Experiment 1, N = 160), or at an assembly line, piecing together equipment sets for furniture (Experiment 2, N = 213). Both experiments provide consistent evidence that high repetitiveness has a detrimental effect on well‐being, whereas work performance increases under conditions of high repetitiveness. On a practical level, our study hence shows that high task repetitiveness is a double‐edged sword for both employees and organizations. On a conceptual level, our findings emphasize the necessity to account for both mental strain and work performance when examining the effects of task repetitiveness.

An empirical survey of the benefits of implementing pay for safety scheme (PFSS) in the Hong Kong construction industry

Introduction

The Government of the Hong Kong Special Administrative Region (SAR) has implemented different safety initiatives to improve the safety performance of the construction industry over the past decades. The Pay for Safety Scheme (PFSS), which is one of the effective safety measures launched by the government in 1996, has been widely adopted in the public works contracts. Both the accident rate and fatality rate of public sector projects have decreased noticeably over this period.

Method

This paper aims to review the current state of application of PFSS in Hong Kong, and attempts to identify and analyze the perceived benefits of PFSS in construction via an industry-wide empirical questionnaire survey. A total of 145 project participants who have gained abundant handson experience with the PFSS construction projects were requested to complete a survey questionnaire to indicate the relative importance of those benefits identified in relation to PFSS. The perceived benefits were measured and ranked from the perspectives of the client and contractor for crosscomparison.

Results

The survey findings suggested the most significant benefits derived from adopting PFSS were: (a) Increased safety training; (b) Enhanced safety awareness; (c) Encouragement of developing safety management system; and (d) Improved safety commitment. A wider application of PFSS should be advocated so as to achieve better safety performance within the construction industry.

Impact on Industry

It is recommended that a similar scheme to the PFSS currently adopted in Hong Kong may be developed for implementation in other regions or countries for international comparisons.     

Underwater LNG release test findings: Experimental data and model results

An underwater LNG release test was conducted to understand the phenomena that occur when LNG is released underwater and to determine the characteristic of the vapor emanating from the water surface. Another objective of the test was to determine if an LNG liquid pool formed on the water surface, spread and evaporated in a manner similar to that from an on-the-surface release of LNG.A pit of dimensions 10.06 m × 6.4 m and 1.22 m depth filled with water to 1.14 m depth was used. A vertically upward shooting LNG jet was released from a pipe of 2.54 cm diameter at a depth of 0.71 m below the water surface. LNG was released over 5.5-min duration, with a flow rate of 0.675 ± 0.223 L/s. The wind speed varied between 2 m/s and 4 m/s during the test.Data were collected as a function of time at a number of locations. These data included LNG flow rate, meteorological conditions, temperatures at a number of locations within the water column, and vapor temperatures and concentrations in air at different downwind locations and heights. Concentration measurements were made with instruments on poles located at 3.05 m, 6.1 m and 9.14 m from the downwind edge of the pit and at heights 0.46 m, 1.22 m, and 2.13 m. The phenomena occurring underwater were recorded with an underwater video camera. Water surface and in-air phenomena including the dispersion of the vapor emanating from the water surface were captured on three land-based video cameras.The lowest temperature recorded for the vapor emanating from the water surface was −1 °C indicating that the vapor emitted into air was buoyant. In general the maximum concentration observed at each instrument pole was progressively at higher and higher elevations as one traveled downwind, indicating that the vapor cloud was rising. These findings from the instrument recorded data were supported by the visual record showing the “white” cloud rising, more or less vertically, in air. No LNG pool was observed on the surface of water. Discussions are provided on the test findings and comparison with predictions from a previously published theoretical model.     

Experimental data and CFD performance for cloud dispersion analysis: The USP-UPC project

Forecasting the behaviour of a flammable or toxic cloud is a critical challenge in quantitative risk analysis. Recent literature shows that empirical and integral models are unable to model complex dispersion scenarios, like those occurring in semi-confined spaces or with the presence of physical barriers. Although CFD simulators are promising tools in this regard, they still need to be fully validated with comprehensive datasets coming from experimental campaigns designed ad-hoc. In this paper, we present an experimental campaign carried out by a joint venture between University of São Paulo and Universitat Politècnica de Catalunya to investigate CFD tools performance when used to analyse clouds dispersion. The experiments consisted on propane cloud dispersion field tests (unobstructed and with the presence of a fence obstructing the flow) of releases up to 0.5 kg s⁻¹ of 40 s of duration in a discharge area of 700 m². We provide a full 1-s averaged propane concentration evolution dataset of two experiments, extracted from 29 points located at different positions within the cloud, with which we have tested FLACS^® CFD-software performance. FLACS reproduces successfully the presence of complex geometry, showing realistic concentration decreases due to cloud dispersion obstruction by the existence of a fence. However, simulated clouds have not represented the whole complex accumulation dynamics due to wind variation.     

Pool evaporation: Experimental tests at medium-scale with gasoline

Pool evaporation is a major source of flammable vapour clouds. Predicting the evaporation rate of a liquid hydrocarbon pool is therefore a key issue of dispersion modelling for safety concerns. This paper presents small- and medium-scale experiments of pool evaporation carried out with liquid hydrocarbons (pentane, heptane), hydrocarbon “gasoline-like” mixtures and gasoline. Liquid mass loss was measured and the evaporation rate deduced with its evolution in time. Other observations are highlighted, regarding the evolution of liquid temperatures, mixture compositions, and scale effects like the influence of pool length on surface evaporation rate. Comparisons with well-known correlations are then shown. The authors finally suggest a new semi-empirical correlation with a set of parameters fitted on the performed experiments.     

Let's get this meeting started: Meeting lateness and actual meeting outcomes

Meeting lateness is pervasive and potentially highly consequential for individuals, groups, and organizations. In Study 1, we first examined base rates of lateness to meetings in an employee sample and found that meeting lateness is negatively related to both meeting satisfaction and effectiveness. We then conducted 2 lab studies to better understand the nature of this negative relationship between meeting lateness and meeting outcomes. In Study 2, we manipulated meeting lateness using a confederate and showed that participants' anticipated meeting satisfaction and effectiveness were significantly lower when meetings started late. In Study 3, participants holding actual group meetings were randomly and blindly assigned to either a 10 min late, 5 min late, or a control condition (n = 16 groups in each condition). We found significant differences concerning participants' perceived meeting satisfaction and meeting effectiveness, as well as objective group performance outcomes (number, quality, and feasibility of ideas produced in the meeting). We also identified differences in negative socioemotional group interaction behaviors depending on meeting lateness. In concert, our findings establish meeting lateness as an important organizational phenomenon and provide important conceptual and empirical implications for meeting research and practice.     

Emissions of volatile hydrocarbons from floating roof tanks and their local dispersion: Considerations for normal operation and in case of damage

This work investigates the release and dispersion of volatile organic hydrocarbons, which may escape from external floating roof tanks (EFRT) during normal operation or in case of damage. The dispersion will be described using CFD simulations in close range of the EFRT where hazardous areas are assigned. The aim of this work is to investigate which events can lead to emissions in dangerous quantities and to estimate the corresponding likelihood with regard to explosion protection. An emission in hazardous amount is present if the lower explosion limit has been exceeded and if the extent of this emission is not too low. It is discussed in particular whether the used zoning of potentially explosive areas is conservative or over-conservative.     

Memento Mori: The development and validation of the Death Reflection Scale

Despite its potential for advancing organizational behavior (OB) research, the topic of death awareness has been vastly understudied. Moreover, research on death awareness has predominantly focused on the anxiety‐provoking aspect of death‐related cognitions, thus overlooking the positive aspect of death awareness, death reflection. This gap is exacerbated by the lack of a valid research instrument to measure death reflection. To address this issue, we offer a systematic conceptualization of death reflection, develop the Death Reflection Scale, and assess its psychometric properties across four studies. Further, using a sample of 268 firefighters, we examine whether death reflection buffers the detrimental impact of mortality cues at work on employee well‐being and safety performance. Results provide strong support for the psychometric properties of the Death Reflection Scale. Further, moderation analysis indicates death reflection weakens the negative effect of mortality cues on firefighters' safety performance. Overall, these findings suggest the newly developed Death Reflection Scale will prove useful in future research on death‐related cognitions.     

CFD simulations of dust dispersion in the 20 L vessel: Effect of nominal dust concentration

Measurements of flammability and explosion parameters for dust/air mixtures require uniform dispersion of the dust cloud inside the test vessel. In a previous work, we showed that, in the standard 20 L sphere, the dust injection system does not allow generation of a uniform cloud, but rather high gradients of dust concentration are established. In this work, we used a previously validated three-dimensional CFD model to simulate the dust dispersion inside the 20 L sphere at different dust nominal concentrations (and fixed dust diameter). Results of numerical simulations have shown that, as the dust nominal concentration is increased, sedimentation prevails and, thus, when ignition is provided, the dust is mainly concentrated at the vessel walls.     

Rivals or allies: How performance‐prove goal orientation influences knowledge hiding

Previous research suggests that performance‐prove goal orientation is positively related to knowledge hiding. However, we argue that this effect depends on the focus of performance feedback (i.e., individual‐ and group‐focused feedback), which shapes the nature of the competitive expression of performance‐prove goal orientation (i.e., intragroup and intergroup oriented). We conducted three studies to test our theoretical model. The results of Study 1 with time‐lagged data from 128 part‐time MBA students showed that performance‐prove goal orientation was positively related to knowledge hiding when performance feedback focused more (vs. less) on individual performance but was negatively related to knowledge hiding when performance feedback focused more (vs. less) on group performance. Study 2 replicated these moderation findings in an experimental study of 210 undergraduate students. Study 3 again replicated the moderation effects using multisource data from 317 employees and their supervisors. It also included creativity as an outcome of knowledge hiding and illustrated the distal consequence of the moderation effects of individual‐ and group‐focused performance feedback. We then discussed the implications for the theory and practice of performance‐prove goal orientation and knowledge hiding.     

The Janus face of paternalistic leaders: Authoritarianism,benevolence, subordinates' organization‐based self‐esteem,and performance

We investigated how the two components of paternalistic leadership, namely authoritarianism and benevolence, jointly influenced work performance through their impacts on organization‐based self‐esteem (OBSE). Using a sample of 686 supervisor–subordinate dyads collected from a manufacturing firm in the People's Republic of China, we found that OBSE mediated the negative relationship between authoritarian leadership on one hand and subordinate task performance and organizational citizenship behavior toward the organization (OCBO) on the other. We also found that the negative effect of authoritarian leadership on subordinate OBSE, task performance, and OCBO was weaker when supervisors exhibited higher levels of leader benevolence. Also, OBSE mediated the joint effect of authoritarian leadership and benevolent leadership on subordinate task performance and OCBO. Copyright © 2012 John Wiley & Sons, Ltd.     

Source attribution matters: Mediation and moderation effects in the relationship between work‐to‐family conflict and job satisfaction

On the basis of the source attribution perspective of work–family conflict, this study aims to first test whether threat to the family role mediates the relationship between work‐to‐family conflict and job satisfaction. We then examine boundary conditions of the source attribution perspective by drawing on boundary management and gender role orientation theories to examine whether role segmentation enactment and gender role orientation moderate the relationship between work‐to‐family conflict and job satisfaction. Using a scenario‐based experiment in Study 1, we find that threat to the family role mediates the relationship between work‐to‐family conflict and job satisfaction. This finding provides evidence supporting the appraisal process proposed by the perspective of source attribution. Using survey data collected from 216 Chinese managers and their spouses in Study 2, we find that work‐to‐family conflict has a negative relationship with job satisfaction only among people with high levels of role segmentation between work and home. In addition, for male managers, the negative moderating effect of role segmentation enactment on the relationship between work‐to‐family conflict and job satisfaction is stronger for those with a nontraditional gender role orientation, compared with those with a traditional gender role orientation. Theoretical and managerial implications are discussed.     

Leader‐signaled knowledge hiding: Effects on employees' job attitudes and empowerment

The authors introduce the concept of leader‐signaled knowledge hiding (LSKH) and conduct two studies observing what happens when leaders signal employees that knowledge hiding (KH) is practiced, tolerated, and expected. Social learning theory provides the basis for predicting that LSKH encourages subordinates to hide knowledge, even though they suffer from negative job attitudes in reaction. In Study 1, data measured at two time points (N = 1,162) shows that LSKH positively predicts KH among subordinates. The KH dimensions of evasive hiding and playing dumb (but not rationalized hiding) negatively relate to job satisfaction and positively affect turnover intentions. Study 2 (N = 1,169) replicates these results with cross‐sectional data. Moreover, Study 2 demonstrates that evasive hiding and playing dumb negatively affect empowerment, whereas rationalized hiding has a positive effect. Both studies reveal that subordinates will show less KH when they work under leaders who avoid LSKH and in turn have more job satisfaction, feel more empowered, and harbor fewer turnover intentions. The results in this study provide important practical implications for knowledge management activities.     

A meta‐analysis of sleep and work performance: An examination of moderators and mediators

The present study utilizes meta‐analytic techniques to examine the literature on sleep and work performance. In line with previous meta‐analytic research, results indicate that sleep and work performance have a positive relationship. However, more importantly, results from moderator analyses reveal that the type of sleep measurement (sleep quantity and sleep quality), work performance measurement (task performance, organizational citizenship behavior, and counterproductive work behavior), analysis method (between‐person and within‐person), sleep report source (self‐report, other report, and objective), sleep recall window (day, week/month, and more than 1 month), and study setting (field and laboratory) differentially influence the strength of the sleep–work performance relationship. Furthermore, meta‐analytic SEM results indicate that certain mediators (affect, job attitudes, and cognitive resources) provide stronger explanations (i.e., stronger indirect effects) for the relationship between sleep and work performance, depending on the specific type of performance being examined. In general, results highlight the importance of construct operationalization and methodology decisions when conducting sleep–work performance research and provide greater insight into explanations for the relationship between sleep and work performance. Research implications, practical implications, potential limitations, and future directions are also discussed.     

Examining the effects of feeling trusted by supervisors in the workplace: A self‐evaluative perspective

Trusting and feeling trusted are related but unique components of a trusting relationship. However, we understand relatively little about the effects of felt trust on work performance and organizational citizenship behavior. From a self‐evaluative perspective, this study argued that when employees perceive that their supervisors trust them, their organization‐based self‐esteem is enhanced, leading them to perform better in the workplace. We tested our hypotheses on a sample of 497 teachers using two trust measures, that is, reliance and disclosure, and found support for them on the basis of the reliance (but not the disclosure) measure. The effect of felt trust especially reliance on the employees' work performances were mediated by their organization‐based self‐esteem. Copyright © 2013 John Wiley & Sons, Ltd.     

The relation between emotional intelligence and job performance: A meta‐analysis

This meta‐analysis builds upon a previous meta‐analysis by (1) including 65 per cent more studies that have over twice the sample size to estimate the relationships between emotional intelligence (EI) and job performance; (2) using more current meta‐analytical studies for estimates of relationships among personality variables and for cognitive ability and job performance; (3) using the three‐stream approach for classifying EI research; (4) performing tests for differences among streams of EI research and their relationships with personality and cognitive intelligence; (5) using latest statistical procedures such as dominance analysis; and (6) testing for publication bias. We classified EI studies into three streams: (1) ability‐based models that use objective test items; (2) self‐report or peer‐report measures based on the four‐branch model of EI; and (3) “mixed models” of emotional competencies. The three streams have corrected correlations ranging from 0.24 to 0.30 with job performance. The three streams correlated differently with cognitive ability and with neuroticism, extraversion, openness, agreeableness, and conscientiousness. Streams 2 and 3 have the largest incremental validity beyond cognitive ability and the Five Factor Model (FFM). Dominance analysis demonstrated that all three streams of EI exhibited substantial relative importance in the presence of FFM and intelligence when predicting job performance. Publication bias had negligible influence on observed effect sizes. The results support the overall validity of EI. Copyright © 2010 John Wiley & Sons, Ltd.
