Journal editors serve as gatekeepers of knowledge, a role critical to preserving the quality and standards of good research. Some scholars have questioned whether editors have taken advantage of their position to publish their own work. To understand the extent to which editors of public administration journals self-publish, we examined publishing patterns over a 20-year period. We collected the names of editors from the mastheads of 13 generalist public administration journals from 1997 to 2016 and used data indexed from Web of Science to look at articles published in those journals during the same time. We found that while self-publishing behaviour is not common across the entire field, it is a trend for certain journals and individuals. We also found the practice of self-publishing is influenced by whether an individual served in a primary editorial role (e.g., editor-in-chief), length of editorial service, and overall scholarly productivity. We discuss appropriateness and ethical implications of the practice. 相似文献

This article examines the extent to which central bankers have been willing and able to rethink their beliefs about monetary policy in the wake of the global financial crisis. We show that despite the upheaval, the core pre‐crisis monetary policy paradigm remains relatively intact: central bankers believe that they should primarily pursue price stability through targeting a low inflation rate in a transparent manner, and that they need operational independence in order to achieve this goal. In a bid to address post‐crisis conditions and maintain their credibility, however, central bankers have also layered new elements onto this paradigmatic core. We document both the resilience of pre‐crisis beliefs and the process of layering using computer‐assisted text analysis and qualitative analysis of 13,586 speeches given between 1997 and 2017 by central bankers from around the world. 相似文献

Few studies have examined risk factors of childhood and early adolescent depressive symptomatology trajectories. This study
examined self-report depressive symptomatology across a 6-year time period from 2nd to 8th grade to identify latent groups
of individuals with similar patterns of depressive phenomena in a sample of 951 children (440 girls, 511 boys). Analyses,
using semiparametric group modeling (SGM), identified 5 trajectory groups for girls and boys: low depressed stables, low depressed
risers, mildly depressed stables, moderately depressed changers, and moderately depressed risers. Individual risk factors,
with the exception of shy/withdrawn behavior, were significantly different across trajectory group membership for boys and
girls, as was low-income status for boys. Boys in the low depressed and mildly depressed stable trajectory groups had significantly
higher levels of antisocial behavior, attention problems, and lower social competency compared to girls in similar groups.
These results suggest that universal prevention programs implemented in early elementary school that target selected risk
factors may be helpful in reducing future adolescent mental health problems, specifically depressive symptomatology. 相似文献

Much economic policy is deliberately shifted away from direct political processes to administrative processes—political pressure deflection. Pressure deflection poses a puzzle to standard political economy models which suggest that having policies to ‘sell’ is valuable to politicians. The puzzle is solved here by showing that incumbents will favor pressure deflection since it can deter viability of a challenger, essentially like entry deterrence. U.S. trade policy since 1934 provides a prime example, especially antidumping law and its evolution. 相似文献

The riskiness of state employee pension plan portfolios varies across states. We investigate whether this variation is related to how public employees and taxpayers share actuarial surpluses of pension accounts. We focus on two determinants of a plan’s asset mix: the relative influence of public employees to taxpayers; and whether a surplus-sharing contract is specified. Our theoretical model demonstrates that the effect of public employee influence on the asset mix is ambiguous. Our empirical results corroborate this complex theoretical result. In our theoretical and empirical analyses, if a surplus sharing rule is specified, plans adopt a more aggressive investment allocation. 相似文献

In this note, new data concerning the agrarian structure of Bangladesh are employed to test the efficacy of ceilings on the size of landholdings as a means of making land available to the landless and the near landless. The data confirm that the numbers of potential claimants for land far exceeds the potential supply, even if ceilings on holdings were lowered from 100 standard bighas (331/3 acres) to 25 standard bighas (81/3 acres). 相似文献
