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

Strikes are more common in those OECD countries where the legislature is elected in single member districts (SMD) than in those where it is elected by proportional representation (PR). Furthermore, more working days are lost due to industrial conflict in countries with SMD. I suggest a politico-economic explanation for these rarely noticed empirical regularities. Further empirical testing – including controls drawn from previous strike research – reveals that they hold up in a variety of econometric specifications.  相似文献

A 6-year longitudinal panel study investigated the absolute and relative stability in depressed mood throughout adolescence by reporting data from a sample of 538 adolescents between 13 and 19 years of age. Results revealed the following. (1) Girls had on average higher depressed mood scores than boys at all ages. (2) Among boys there were no substantial changes in depressed mood mean scores, while among girls there was a slight tendency of a curvilinear trend, with a peak level reached in midadolescence. (3) There was a tendency for adolescents to retain their relative level in depressed mood, most pronounced for a period of 4 years, from age 15 to age 19 years. (4) Depressed mood was most stable in a subgroup of adolescents who had high initial depressed mood scores. (5) By applying structural equation modeling, it was shown that the stable (trait) component of depressed mood increased in importance with increasing age, while the temporal (state) component decreased with increased age.  相似文献

This paper describes an effort to develop a clinical tool for the continuous monitoring of risk for violence in forensic mental health clients who have left their institutions and who are dwelling in the community on a conditional release basis. The model is called Structured Outcome Assessment and Community Risk Monitoring (SORM). The SORM consists of 30 dynamic factors and each factor in SORM is assessed in two ways: The current absence, presence or partial och intermittent presence of the factors, which is an actuarial (systematized and 'objective') assessment. Secondly, the risk effect, i.e. whether the presence/absence of factors currently increases, decreases or is perceived as unrelated to violence risk, is a clinical (or impressionistic) assessment. Thus, the factors considered via the SORM can be coded as risk factors or protective factors (or as factors unimportant to risk of violence) depending on circumstances that apply in the individual case. Further, the SORM has a built-in module for gathering idiographical information about risk-affecting contextual factors. The use of the SORM and its potential as a risk monitoring instrument is illustrated via preliminary data and case vignettes from an ongoing multicenter project. In this research project, patients leaving any of the 9 participating forensic hospitals in Sweden is assessed at release on a variety of static background factors, and the SORM is then administered every 30 days for 2 years.  相似文献

Experimental data useful for the interpretation of paint evidence recovered during burglary cases were obtained. A population study was carried out on 41 blue crowbars seized on suspects in Switzerland and 37 blue paints traces found at burglary scenes. Paint traces were also searched on the blades of 207 crowbars seized by the police in Switzerland and 24 white traces were analysed: these paints were analysed using infrared spectroscopy (FTIR) in order to estimate relative frequencies of each paint type. Simulated contacts were carried out between crowbars and painted wood in order to study the phenomenon of transfer and to evaluate the amount of paint transferred: a total of 198 simulations were carried out including individual, successive and cross transfer. The paint properties such as the chemical composition and its age influenced the amount of paint transferred. Cross transfer from the tool paint to the wood and vice versa was regularly observed. Moreover, secondary transfer of paint coming from the preceding wooden surfaces was also systematically observed: this could establish links between several burglary scenes and a suspected tool. A scenario of a burglary case involving the cross transfer between tool and household paints is proposed as a numerical example: the evaluation of such case was formalised using likelihood ratios based on the experimental data obtained.  相似文献
