Although there is a growing interest toward the topic of leader humility, extant research has largely failed to consider the underlying mechanisms through which leader humility influences team ...outcomes. In this research, we integrate the emerging literature of leader humility and social information processing theory to theorize how leader humility facilitates the development of collective team psychological capital, leading to higher team task allocation effectiveness and team performance. While Owens and Hekman (2016) suggest that leader humility has homogeneous effects on followers, we propose a potential heterogeneous effect based on the complementarity literature (e.g., Tiedens, Unzueta, & Young, 2007) and the principle of equifinality (leaders may influence team outcomes through multiple pathways; Morgeson, DeRue, & Karam, 2010). In three studies conducted in China, Singapore, and Portugal, including an experiment, a multisource field study, and a three-wave multisource field study, we find support for our hypotheses that leader humility enhances team performance serially through increased team psychological capital and team task allocation effectiveness. We discuss the theoretical implications of our work to the leader humility, psychological capital, and team effectiveness literatures; and offer suggestions for future research.

eBook, Book
Written in a clear and non-technical manner, Retaking Rationality gives progressive groups and the public the tools they need both to understand and to engage in the debate over the economic analysis ...of environmental, public health, and safety regulation. Since the Reagan presidency, the most important regulations affecting every American have been required to pass a "cost-benefit" test, but most Americans-including many professionals working for progressive institutions or elected officials-do not understand how economic analysis works. The result is that industry and conservative ideologues have twisted economic analysis so that good regulations seem to fail the cost-benefit test. This book argues that the public, and progressive institutions, must take up the fight over how economic analysis is conducted, and gives them the knowledge they need to engage industry and conservatives about when and how economic analysis of regulation should be carried out.
Background and Aims
In this follow‐up study to a randomized controlled trial of a chronic disease management (CDM) model in cirrhosis, our aim was to assess the relative cost‐effectiveness of this ...model compared with usual care during the 12‐month study period, using incremental costs per death avoided as the primary outcome.
Methods
Mean differences in hospitalization costs, deaths avoided, and change in Chronic Liver Disease Questionnaire (CLDQ) total scores were presented with 95% non‐parametric bootstrapped confidence intervals. Results were also presented using a cost‐effectiveness plane (CEP) and cost‐effectiveness acceptability curve.
Results
The CDM intervention was more expensive, by 18 521 AUD per participant, but more effective (% of deaths at 12 months: 10% vs 15% and 0.67 units increase per patient in CLDQ total scores). The resultant incremental cost‐effectiveness ratios were 370 425 AUD per death avoided (95% confidence interval: −14 564 AUD to 2 059 373 AUD) and 27 547 AUD per unit improvement in the CLDQ total score (95% CI: 7455 AUD to 143 874 AUD). The CEPs demonstrated some uncertainty around cost‐effectiveness. The cost‐effectiveness acceptability curves demonstrated that at willingness to pay values of 400 000 AUD per additional death avoided and 40 000 AUD per unit improvement in the CLDQ, there was at least a 70% probability of CDM being more cost‐effective than usual care. At 24 months, CDM was much more effective (12% less deaths but now also cheaper by 985 AUD per patient).
Conclusions
The analysis of data from a randomized controlled trial suggests that the CDM intervention used is likely to be cost‐effective, relative to usual care, due to fewer patient deaths.
Diffuse support for democracy, as captured in mass surveys, tends to be treated as impervious to regime performance. Such a finding is often presented as confirmation of the basic distinction between ...‘diffuse’ and ‘specific’ support as proposed by David Easton. This study argues that this line of argument stems from an incomplete reading of important aspects of Easton's theorisation about the relationship between system outputs and diffuse support. Using multilevel models, evidence from more than 100 surveys in close to 80 countries, and different measures of democratic support, it is shown that government effectiveness is the strongest macro‐level predictor of such support. In democratic regimes, government effectiveness, understood as the quality of policy‐making formulation and implementation, is linked to higher levels of support for democracy. Furthermore, in non‐democracies, effectiveness and support for democracy are, under some model specifications, negatively related.
The purpose of this paper is to systematically review the academic literature on organizational effectiveness (OE) through an analysis of 134 contributions. While OE is the most important goal for an ...organization, research views on this construct are diversified. Over time, the literature has increasingly focused on antecedents, measures, and more diversified approaches to OE. This paper contributes to the OE literature by developing an integrated conceptual model that considers the levels of antecedents (individual, group, and organizational) as well as measures of OE (financial, operational, structural, and attitudinal). Previous research has focused primarily on organizational-level antecedents and non-financial measures of OE. The paper also discusses the barriers hampering the measurement of OE. An agenda for future research is also provided.
•Organizational effectiveness is a complex and prominent construct.•Individual, Group and Organizational, all three factors influence organizational effectiveness.•Non-financial measures are equally important as the financial measures.•Measurement of organizational effectiveness is divergent.•Measurement is not free from barriers.
A blood-based colorectal cancer (CRC) screening test may increase screening participation. However, blood tests may be less effective than current guideline-endorsed options. The Centers for Medicare ...& Medicaid Services (CMS) covers blood tests with sensitivity of at least 74% for detection of CRC and specificity of at least 90%. In this study, we investigate whether a blood test that meets these criteria is cost-effective.
Three microsimulation models for CRC (MISCAN-Colon, CRC-SPIN, and SimCRC) were used to estimate the effectiveness and cost-effectiveness of triennial blood-based screening (from ages 45 to 75 years) compared to no screening, annual fecal immunochemical testing (FIT), triennial stool DNA testing combined with an FIT assay, and colonoscopy screening every 10 years. The CMS coverage criteria were used as performance characteristics of the hypothetical blood test. We varied screening ages, test performance characteristics, and screening uptake in a sensitivity analysis.
Without screening, the models predicted 77–88 CRC cases and 32–36 CRC deaths per 1000 individuals, costing $5.3–$5.8 million. Compared to no screening, blood-based screening was cost-effective, with an additional cost of $25,600–$43,700 per quality-adjusted life-year gained (QALYG). However, compared to FIT, triennial stool DNA testing combined with FIT, and colonoscopy, blood-based screening was not cost-effective, with both a decrease in QALYG and an increase in costs. FIT remained more effective (+5–24 QALYG) and less costly (–$3.2 to –$3.5 million) than blood-based screening even when uptake of blood-based screening was 20 percentage points higher than uptake of FIT.
Even with higher screening uptake, triennial blood-based screening, with the CMS-specified minimum performance sensitivity of 74% and specificity of 90%, was not projected to be cost-effective compared with established strategies for colorectal cancer screening.
Current test performance characteristics of blood-based colorectal cancer screening tests are insufficient to justify their high costs compared with less expensive and more effective alternatives such as fecal immunochemical testing, triennial stool DNA testing combined with a fecal immunochemical testing assay, and colonoscopy.
Team trust has often been discussed both as requirement and as challenge for team effectiveness, particularly in virtual teams. However, primary studies on the relationship between trust and team ...effectiveness have provided mixed findings. The current review summarizes existing studies on team trust and team effectiveness based on meta-analytic methodology. In general, we assumed team trust to facilitate coordination and cooperation in teams, and therefore to be positively related with team effectiveness. Moreover, team virtuality and documentation of interactions were considered as moderators of this relationship because they should affect perceived risks during teamwork. While team virtuality should increase, documentation of interaction should decrease the relationship between team trust and team effectiveness. Findings from 52 studies with 54 independent samples (representing 12,615 individuals in 1,850 teams) confirmed our assumptions. In addition to the positive overall relationship between team trust and team effectiveness criteria (ρ = .33), the relationship between team trust and team performance was stronger in virtual teams (ρ = .33) as compared to face-to-face teams (ρ = .22), and weaker when team interactions were documented (ρ = .20) as compared to no such documentation (ρ = .29). Thus, documenting team interactions seems to be a viable complement to trust-building activities, particularly in virtual teams.
