The Impact

Purpose The purpose of this paper is to identify the impact of public support through equity instruments on firm performance, as measured by growth in employment, turnover and innovative activities. Design/methodology/approach The paper draws on available academic literature and policy evaluation studies and using a mixed-method approach based on evaluation synthesis. Findings The key findings reflect positive, albeit quantifiably small, outcomes for this type of policy intervention for employment and turnover and no effect on innovation. There is some concentration of positive results, which is also dependent on the number and quality of the available target companies. Research limitations/implications The evaluations used in this study vary considerably in their design, nature and the input and output variables used and, thus, limit a robust comparison of their outputs. Most of the evaluations examined in this paper did not control for multiple simultaneous treatment effects and/or subsequent funding rounds. Practical implications The evaluations are rarely designed to compare the treatment effects of alternative policy choices. Only seldom is an evaluation designed to assess the impact of the scheme in the context of the broader policy mix (with its framework conditions, etc.) which would provide more fine-grained policy implications. Originality/value The recent literature (Duruflé et al., 2017, Da Rin et al., 2011) highlights the dearth of studies exploring the role of government policies supporting venture and, more broadly, equity investments beyond comparisons of the efficiency of independent venture capital and government-backed venture capital. Most studies explore the impact in terms of exits, initial public offering and leverage effects whereas fewer studies look at output effects on companies such as turnover and employment growth. The paper aims to collect the existing evidence including less analysed policy evaluation studies and draw lessons for public policy.

Purpose This study continued Phase I investigation of a modified Phonomotor Treatment (PMT) Program on motor planning in two individuals with apraxia of speech (AOS) and aphasia and, with support from prior work, refined Phase I methodology for treatment intensity and duration, a measure of communicative participation, and the use of effect size benchmarks specific to AOS. Method A single-case experimental design with multiple baselines across behaviors and participants was used to examine acquisition, generalization, and maintenance of treatment effects 8–10 weeks posttreatment. Treatment was distributed 3 days a week, and duration of treatment was specific to each participant (criterion based). Experimental stimuli consisted of target sounds or clusters embedded nonwords and real words, specific to each participants' deficit. Results Findings show improved repetition accuracy for targets in trained nonwords, generalization to targets in untrained nonwords and real words, and maintenance of treatment effects at 10 weeks posttreatment for one participant and more variable outcomes for the other participant. Conclusions Results indicate that a modified version of PMT can promote generalization and maintenance of treatment gains for trained speech targets via a multimodal approach emphasizing repeated exposure and practice. While these results are promising, the frequent co-occurrence of AOS and aphasia warrants a treatment that addresses both motor planning and linguistic deficits. Thus, the application of traditional PMT with participant-specific modifications for AOS embedded into the treatment program may be a more effective approach. Future work will continue to examine and maximize improvements in motor planning, while also treating anomia in aphasia.

Abstract. We examined the effect of presenting unknown policy statements on German parties’ election posters. Study 1 showed that participants inferred the quality of a presented policy from knowledge about the respective political party. Study 2 showed that participants’ own political preferences influenced valence estimates: policy statements presented on campaign posters of liked political parties were rated significantly more positive than those presented on posters of disliked political parties. Study 3 replicated the findings of Study 2 with an additional measure of participants’ need for cognition. Need for cognition scores were unrelated to the valence transfer from political parties to policy evaluation. Study 4 replicated the findings of Studies 2 and 3 with an additional measure of participants’ voting intentions. Voting intentions were a significant predictor for valence transfer. Participants credited both their individually liked and disliked political parties for supporting the two unknown policies. However, the credit attributed to the liked party was significantly higher than to the disliked one. Study 5 replicated the findings of Studies 2, 3, and 4. Additionally, participants evaluated political clubs that were associated with the same policies previously presented on election posters. Here, a second-degree transfer emerged: from party valence to policy evaluation and from policy evaluation to club evaluation. Implications of the presented studies for policy communications and election campaigning are discussed.
