Does higher employee wellbeing lead to productivity, and, ultimately, tangible benefits the bottom line of businesses? We survey evidence and study this question in a meta-analysis 339 independent research studies, including 1,882,131 employees performance 82,248 business units, originating from 230 organisations across 49 industries Gallup client database. find significant, strong positive correlation between employees' satisfaction with their company productivity customer loyalty, negative...
This paper provides evidence from a natural experiment on the relationship between positive affect and productivity. We link highly detailed administrative data behaviors performance of all telesales workers at large telecommunications company with survey reports employee happiness that we collected weekly basis. use variation in worker mood arising visual exposure to weather—the interaction call center architecture outdoor weather conditions—to provide quasi-experimental test effect find...
Laboratory—determined larval growth rates of the detritivore (collector—gatherer) Paratendipes albimanus (Chironomidae) responded proportionally to microbial densities 4 food sources. Substrates with higher activities and biomasses produced greater in order: pignut hickory (Carya glabra) leaves > white oak (Quercus alba) insect feces natural stream detritus. Laboratory P. were linearly related quantitative estimates quality based on substrate adenosine triphosphate (ATP) respiration but...
Are individuals more sensitive to losses than gains in terms of economic growth? We find that measures subjective well-being are twice as negative compared positive growth. use Gallup World Poll data from over 150 countries, BRFSS on 2.3 million US respondents, and Eurobarometer cover multiple business cycles four decades. This research provides a new perspective the welfare cost cycles, with implications for growth policy nature long-run relationship between GDP well-being.

Annual flooding in low-gradient rivers is recognized as an important subsidy between the river and its broad adjoining floodplains. Unfortunately, relatively few are unregulated retain their natural "flood pulse" behavior most developed regions of world. Furthermore, attempts to quantify flood inundation dynamics any floodplain scarce. We used aerial photography delineate degree GIS flooded areas on forested a 6.3-km reach Ogeechee River, sixth-order southeastern USA. A regression was...
A comparison between stream community processing rates of naturally entrained leaf litter and leaves in packs or 1‐mm‐mesh bags demonstrated that served as a suitable analogue exposed sites (riffles) whereas did not. In riffles, were processed at characteristic depositional zones (pools alcoves). length‐weight regression method for evaluating the range microhabitat‐related communities appears suitable. Leaf nitrogen levels increased by shredders reflected microbial conditioning. Shredders...
The detritus standing crop, microbial respiration, and macroinvertebrate biomass were examined in monthly samples from the riffle sections of a first—order woodland stream. Total was remarkably constant; average (with 95% CL) ash—free dry mass crop 426.4 ± 85.9 g/m 2 over 14 mo study. Throughout year benthic dominated by fine particulate (<1 mm), which made up 68.9% total mass. Woody debris 8%, whole leaves 3.5%, leaf fragments other coarse accounted for 19.7% crop. Decreases attributable...
Abstract There is a growing interest among policy makers in the use of subjective well‐being (or “happiness”) data to measure societal progress, as well inform and evaluate public policy. Yet despite sharp rise supply well‐being‐based policymaking, it remains unclear whether there any electoral demand for it. In this article, I study long‐run panel general elections Europe find that strong predictor election results. National measures are able explain more variance governing party vote share...
A rapidly growing literature has attempted to explain Donald Trump's success in the 2016 U.S. presidential election as a result of wide variety differences individual characteristics, attitudes, and social processes.We propose that economic psychological processes previously established have common they generated or electorally capitalized on unhappiness electorate, which emerges powerful high-level predictor electoral outcome.Drawing large dataset covering over 2 million surveys, we...
The distribution and lignocellulolytic activity of the microbial community was determined on a large log Douglas fir ( Pseudotsuga menziesii ) in Pacific Northwest stream. Scanning electron microscopy, plate counts, degradation [ 14 C]lignocelluloses prepared from incubated with samples wood taken surface within revealed that most colonization lignocellulose-degrading occurred surface. Labeled lignocellulose were vitro nutrient supplements to determine potential limiting factors...
The potential contribution of woody debris to fine particulate organic matter pools (0.45 μm ≤ FROM < 1 mm) was investigated in a coniferous forest stream ecosystem western Oregon. amount wetted surface area both large (>10 cm) and (1–10 0.018 0.069 m 2 ∙m −2 bed, respectively, during summer base flow. These values increase 0.062 0.195 bed winter flows. Studies vertical distribution indicated that most wood is concentrated within 0.3 the bottom, while more evenly distributed up 0.7 m....
Summary 1. Species‐discharge relationships (SDR) are aquatic analogues of species‐area relationships, and increasingly used in both basic research conservation planning. SDR studies often limited, however, by two shortcomings. First, they do not determine whether reported SDRs, which normally use complete drainage basins as sampling units, scale dependent. Second, account for the effects habitat diversity within or among samples. 2. We addressed problems using discrete fish zones units a...
Happiness is typically defined by how people experience and evaluate their lives as a whole. Since the majority of spend much at work, it critically important to gain solid understanding role that employment workplace play in shaping happiness for individuals communities around world.
We studied the relationship between geology and lotic secondary production by analyzing geographical patterns of distribution, biomass, freshwater snail Elimia (Pleuroceridae) in Alabama. Nine streams were selected for study, three each physiographically distinct regions uniform climate but contrasting lithology. Our objectives to assess: 1) biomass among with alkalinities due differences regional geology--sandstone (5.7 mg/L as CaCo<sub>3</sub>) < phyllite (19.4) carbonate (103.4); p...
