The Impact

It is easier for voters to make informed electoral choices when parties talk about the same issues. Yet, parties may decide against such “issue engagement.” We hypothesize that issue engagement between parties is more likely (a) when the similarity of their policy positions means that both parties have clearelectoral incentivesto talk about the same topics and (b) when parties face feworganizational constraintsin terms of campaign resources. Our empirical analysis of 2453 press releases by Austrian parties shows that ideological proximity and party resources affect the level of issue engagement. These findings suggest that issue engagement is less likely precisely where it is needed most, which has important implications for understanding the democratic quality of election campaigns.

The Impact

Conducting research on the quality of life of young people and the impact on it of such a significant factor as the youth labor market, as well as related research on the problems of state support for young people, require the use of simulation methods due to the incompleteness of information and poorly structured problems of such complex systems as the quality of life of young people and the labor market. The article gives a brief overview of the categories “labor market”, “quality of life”, “youth”, which is necessary to determine the content of cognitive modeling of the complex system “youth, labor market, quality of life”. The technology of cognitive modeling is briefly presented. The results of the application of cognitive simulation modeling to the study of the quality of life of young people in relation to the labor market are presented. An example of modeling is presented in the form of a corresponding cognitive map and a number of scenarios for the possible development of situations on it, which may arise under the assumed influence of various social and economic factors, as well as under the influence of regulatory and control systems.

The Impact

AbstractPrior research concludes that option introductions improve the average liquidity of the underlying stocks. We develop an improved, generalizable test to assess whether market quality changes occur on or near an event date. Applying this method to option listing events, we conclude that options do not systematically improve the market quality of the underlying security; rather, the market quality of the underlying security improves before the listing decision. Hazard model tests indicate that improving liquidity is a selection criterion in the option listing decision. Moreover, these tests suggest that the size of a stock's bid-ask spread is the single most important option listing determinant.

Purpose The purpose of this study was to identify levels of self-compassion in adults who do and do not stutter and to determine whether self-compassion predicts the impact of stuttering on quality of life in adults who stutter. Method Participants included 140 adults who do and do not stutter matched for age and gender. All participants completed the Self-Compassion Scale. Adults who stutter also completed the Overall Assessment of the Speaker's Experience of Stuttering. Data were analyzed for self-compassion differences between and within adults who do and do not stutter and to predict self-compassion on quality of life in adults who stutter. Results Adults who do and do not stutter exhibited no significant differences in total self-compassion, regardless of participant gender. A simple linear regression of the total self-compassion score and total Overall Assessment of the Speaker's Experience of Stuttering score showed a significant, negative linear relationship of self-compassion predicting the impact of stuttering on quality of life. Conclusions Data suggest that higher levels of self-kindness, mindfulness, and social connectedness (i.e., self-compassion) are related to reduced negative reactions to stuttering, an increased participation in daily communication situations, and an improved overall quality of life. Future research should replicate current findings and identify moderators of the self-compassion–quality of life relationship.
