Reward management: linking employee motivation and organizational performance

Companies invest enormous financial resources in reward systems and practices to attract, retain, and motivate employees and thereby ensure and improve individual, team, and organizational effectiveness. Organizational rewards comprise financial and nonfinancial rewards, such as appreciation, job security, and promotion. Financial rewards, also called tangible rewards, include direct forms (such as fixed and variable pay and share ownership) as well as indirect and/or deferred forms (such as benefits and perquisites). Fixed or base pay refers to the amount of money one receives in return for fulfilling one’s job requirements, the job’s grade, or the skill or competence level required to perform the tasks. Variable pay (such as cash bonuses and commissions as forms of short-term incentives, or stocks or stock options as forms of long-term incentives) depends, for example, on individual, team, and/or company performance or outcomes, and is based on quantitative and/or qualitative criteria. Benefits (such as pension plans or health programs) and perquisites (such as onsite fitness centers, medical care or health facilities, and company cars), among other forms, are indirect financial rewards (Milkovich, Newman, & Gerhart, 2016). Both qualitative reviews (Gerhart & Fang, 2014; Shaw & Gupta, 2015) and meta-analytic studies (Cerasoli, Nicklin, & Ford, 2014; Garbers & Konradt, 2014; Jenkins, Mitra, Gupta, & Shaw, 1998) have shown that extrinsic rewards (such as financial incentives) can improve employee motivation and performance and shape employee health (Giles, Robalino, McColl, Sniehotta, & Adams, 2014) and safety behavior (Mattson, Torbiörn, & Hellgren, 2014). However, empirical evidence regarding under which conditions particular rewards are most effective or lead to unintended consequences is still scarce. In short, compensation and incentive systems remain one of the most under-researched areas in personnel psychology and human resource management (Gupta & Shaw, 2015). This state of affairs poses risks. Reward management approaches may waste both money and effort, and may be ineffective in attracting, retaining, and motivating target personnel, if not grounded in a base of evidence. Added to this, in the face of the recent financial crisis and of serious cases of employee and company unethical behavior, company’s financial incentives, especially bonus and pay-for-performance (pfp) systems, have been widely criticized for their detrimental effects on individuals, companies, and society (Larcker, Ormazabal, Tayan, & Taylor, 2014). These examples of the dark sides of incentives highlight the importance of reward management research, not only from a human resources management (HRM) but also from a societal perspective. They also illustrate the need to understand the underlying mediating and moderating mechanisms linking reward systems and practices to individual, team, and organizational behavior and outcomes. This special issue contributes to the research on reward management by focusing on the contextual effects of financial rewards on employee motivation, behavior, and performance, and by analyzing the mediating mechanisms of different types of financial and nonfinancial rewards. The four studies included in this special issue address different issues of reward management research and take different theoretical perspectives. The first two studies analyze the interaction effects of financial incentives and individual factors, such as employee perceptions of distributive justice, and then how individual competitiveness moderates the effects of pay-for-performance (pfp) on employee motivation, behavior, and performance. These studies show which and how intended or unintended consequences of pfp occur. The other two studies differentiate the effects of tangible and intangible rewards on employee turnover and risk taking; they disentangle underlying mediating and moderating mechanisms by comparing the effects of benefits and perquisites, and of esteem, security, and promotion as nonfinancial rewards. In the following passages, we present a short overview of these four papers before we discuss their contribution and their implications for further research

Characterization and Quantification of Isoprene-Derived Epoxydiols in Ambient Aerosol in the Southeastern United States

Isoprene-derived epoxydiols (IEPOX) are identified in ambient aerosol samples for the first time, together with other previously identified isoprene tracers (i.e., 2-methyltetrols, 2-methylglyceric acid, C5-alkenetriols, and organosulfate derivatives of 2-methyltetrols). Fine ambient aerosol collected in downtown Atlanta, GA and rural Yorkville, GA during the 2008 August Mini-Intensive Gas and Aerosol Study (AMIGAS) was analyzed using both gas chromatography/quadrupole mass spectrometry (GC/MS) and gas chromatography/time-of-flight mass spectrometry (GC/TOFMS) with prior trimethylsilylation. Mass concentrations of IEPOX ranged from ~1 to 24 ng m^(−3) in the aerosol collected from the two sites. Detection of particle-phase IEPOX in the AMIGAS samples supports recent laboratory results that gas-phase IEPOX produced from the photooxidation of isoprene under low-NO_x conditions is a key precursor of ambient isoprene secondary organic aerosol (SOA) formation. On average, the sum of the mass concentrations of IEPOX and the measured isoprene SOA tracers accounted for about 3% of the organic carbon, demonstrating the significance of isoprene oxidation to the formation of ambient aerosol in this region

The thermally-coupled imager: A scalable readout architecture for superconducting nanowire single photon detectors

Although superconducting nanowire single-photon detectors (SNSPDs) are a promising technology for quantum optics, metrology, and astronomy, they currently lack a readout architecture that is scalable to the megapixel regime and beyond. In this work, we have designed and demonstrated such an architecture for SNSPDs, called the thermally-coupled imager (TCI). The TCI uses a combination of time-of-flight delay lines and thermal coupling to create a scalable architecture that can scale to large array sizes, allows neighboring detectors to operate independently, and requires only four microwave readout lines to operate no matter the size of the array. We give an overview of how the architecture functions, and demonstrate a proof-of-concept $32\times32$ imaging array. The array was able to image a free-space focused spot at 373 nm, count at 9.6 Mcps, and resolve photon location with greater than 99.83\% distinguishability

Dynamic and Double-Diffusive Instabilities in a Weak Pycnocline. Part II: Direct Numerical Simulations and Flux Laws

The article of record as published may be found at http://dx.doi.org/10.1175/JPO-D-13-043.1This study examines the interaction of diffusive convection and shear through a series of 2D and 3D direct numerical simulations (DNS). The model employed is based on the Boussinesq equations of motion with oscillating shear represented by a forcing term in the momentum equation. This study calculates thermal diffusivities for a wide range of Froude numbers and density ratios and compares the results with those from the analysis of observational data gathered during a 2005 expedition to the eastern Weddell Sea. The patterns of layering and the strong dependence of thermal diffusivity on the density ratio described here are in agreement with observations. Additionally, the authors evaluate salinity fluxes that are inaccessible from field data and formulate a parameterization of buoyancy transport. The relative significance of double diffusion and shear is quantified through comparison of density fluxes, efficiency factor, and dissipation ratio for the regimes with/without diffusive convection. This study assesses the accuracy of the thermal production dissipation and turbulent kinetic energy balances, commonly used inmicrostructure-based observational studies, and quantifies the length of the averaging period required for reliable statistics and the spatial variability of heat fluxThis work was supported by NSF Grant ANT-0944536.

Seasonal characterization of submicron aerosol chemical composition and organic aerosol sources in the southeastern United States: Atlanta, Georgia,and Look Rock, Tennessee

A year-long near-real-time characterization of non-refractory submicron aerosol (NR-PM1) was conducted at an urban (Atlanta, Georgia, in 2012) and rural (Look Rock, Tennessee, in 2013) site in the southeastern US using the Aerodyne Aerosol Chemical Speciation Monitor (ACSM) collocated with established air-monitoring network measurements. Seasonal variations in organic aerosol (OA) and inorganic aerosol species are attributed to meteorological conditions as well as anthropogenic and biogenic emissions in this region. The highest concentrations of NR-PM1 were observed during winter and fall seasons at the urban site and during spring and summer at the rural site. Across all seasons and at both sites, NR-PM1 was composed largely of OA (up to 76 %) and sulfate (up to 31 %). Six distinct OA sources were resolved by positive matrix factorization applied to the ACSM organic mass spectral data collected from the two sites over the 1 year of near-continuous measurements at each site: hydrocarbon-like OA (HOA), biomass burning OA (BBOA), semi-volatile oxygenated OA (SV-OOA), low-volatility oxygenated OA (LV-OOA), isoprene-derived epoxydiols (IEPOX) OA (IEPOX-OA) and 91Fac (a factor dominated by a distinct ion at m∕z 91 fragment ion previously observed in biogenic influenced areas). LV-OOA was observed throughout the year at both sites and contributed up to 66 % of total OA mass. HOA was observed during the entire year only at the urban site (on average 21 % of OA mass). BBOA (15–33 % of OA mass) was observed during winter and fall, likely dominated by local residential wood burning emission. Although SV-OOA contributes quite significantly ( ∼  27 %), it was observed only at the urban site during colder seasons. IEPOX-OA was a major component (27–41 %) of OA at both sites, particularly in spring and summer. An ion fragment at m∕z 75 is well correlated with the m∕z 82 ion associated with the aerosol mass spectrum of IEPOX-derived secondary organic aerosol (SOA). The contribution of 91Fac to the total OA mass was significant (on average 22 % of OA mass) at the rural site only during warmer months. Comparison of 91Fac OA time series with SOA tracers measured from filter samples collected at Look Rock suggests that isoprene oxidation through a pathway other than IEPOX SOA chemistry may contribute to its formation. Other biogenic sources could also contribute to 91Fac, but there remains a need to resolve the exact source of this factor based on its significant contribution to rural OA mass.</html
