Are self-employment training programs effective? Evidence from Project GATE

In 2002, the U.S. Department of Labor and the Small Business Administration implemented Project GATE, an experimental demonstration program designed to provide free self-employment assistance to individuals interested in starting their own business. This paper uses data from Project GATE to examine the efficacy of public self-employment training programs in the modern U.S. economy. Our analyses show that GATE led to significant improvements in the post-training outcomes of treatment group participants who were unemployed at the time of application. Particularly, GATE had a significant positive impact on new business starts and sustainability for unemployed participants five years after random assignment. For those who were unemployed at random assignment, GATE also led to higher employment likelihood and higher total earnings five years after random assignment. GATE had no impact, however, for participants who were employed, self-employed, or out of the labor force at the time of application.self-employment; small business; unemployment; workforce development; SEA; Project GATE

Evaluating Active Labor Markets in Romania

We evaluate the presence of effects from joining one of four active labour market programs in Romania in the late 1990s compared to the no-program state.  Using rich follow-up survey data and propensity score matching, we find that three programs (training and retraining, self-employment assistance, and employment and relocation services) had success in improving participants' economic outcomes and were cost-beneficial from society's perspective. In contrast, public employment was found detrimental for the employment prospects of its participants.Active labour market programs, propensity score matching, transition economies, and net social benefits

Speech vocoding for laboratory phonology

Using phonological speech vocoding, we propose a platform for exploring relations between phonology and speech processing, and in broader terms, for exploring relations between the abstract and physical structures of a speech signal. Our goal is to make a step towards bridging phonology and speech processing and to contribute to the program of Laboratory Phonology. We show three application examples for laboratory phonology: compositional phonological speech modelling, a comparison of phonological systems and an experimental phonological parametric text-to-speech (TTS) system. The featural representations of the following three phonological systems are considered in this work: (i) Government Phonology (GP), (ii) the Sound Pattern of English (SPE), and (iii) the extended SPE (eSPE). Comparing GP- and eSPE-based vocoded speech, we conclude that the latter achieves slightly better results than the former. However, GP - the most compact phonological speech representation - performs comparably to the systems with a higher number of phonological features. The parametric TTS based on phonological speech representation, and trained from an unlabelled audiobook in an unsupervised manner, achieves intelligibility of 85% of the state-of-the-art parametric speech synthesis. We envision that the presented approach paves the way for researchers in both fields to form meaningful hypotheses that are explicitly testable using the concepts developed and exemplified in this paper. On the one hand, laboratory phonologists might test the applied concepts of their theoretical models, and on the other hand, the speech processing community may utilize the concepts developed for the theoretical phonological models for improvements of the current state-of-the-art applications

Figurative Constructivism, Pictorial Statistics, and the Group of Progressive Artists, c. 1920-1939

This dissertation examines an episode of interdisciplinary collaboration in Vienna during the late 1920s and early 1930s, led by the Austrian social scientist Otto Neurath (1882-1945) and the German printmaker Gerd Arntz (1900-1988). This collaboration, which took place at Vienna's Gesellschafts- und Wirtschaftsmuseum [Social and Economic Museum] ultimately created an international graphic sign language that would have wide-ranging applications across a variety of media and disciplines. Known as the Vienna Method of Pictorial Statistics, this graphic language was intended to communicate social and economic facts to a general audience. In making such information broadly accessible, the Vienna Method's designers hoped to empower the public at large to take informed positions on a variety of social and political issues. Prior to and during the period of this collaboration, Arntz was a member of the Rhineland-based Gruppe progressiver Künstler [Group of Progressive Artists]. In 1929 two additional members of this group—the Dutch artist Peter Alma (1886-1969) and the Czech artist Augustin Tschinkel (1905-1983)—joined Arntz at the museum. All three artists produced prints, drawings, and paintings in an expressive mode, later classified under the rubric "figurative constructivism." While these "free" works (as they often described them) were produced independent of the applied work at the museum, the two types of production share several key stylistic and iconographic features. Yet, the relationship between figurative constructivist artworks and pictorial statistic graphics has until now remained obscure. This dissertation analyzes the nature of this creative relationship by describing the different circumstances out of which the two projects originated, and by examining the manner in which certain figurative constructivist features were adapted in the design of pictorial statistics. In considering the ways in which these two types of work were presented and discussed together in a variety of contemporaneous avant-garde publications, the present investigation will provide new insights concerning the interwar connections between the artistic avant-garde and visual communication in the sciences

Evaluating the impact of active labor programs : results of cross country studies in Europe and Central Asia

The objective of this cross country study was to determine if there was any significant difference those individuals who participated in active labor programs (ALP) and similar individuals who did not participate in the programs (the comparison group), with regard to agreed outcome measures of program success (e.g., employment, wage levels) in four countries: the Czech Republic, Poland, Hungary, and Turkey. The study evaluated five different ALPs across the four countries for several categories of program participants, grouped by demographic characteristics and geographic location. The active labor programs studies comprised: retraining, public works or temporary community employment, wage subsidy, self-employment initiatives, and general employment services. All five ALPs evaluated were found to have a significant positive net impact for some population subgroups, a general finding supported by the 1996 OECD review that concluded that there are ALPs that work for most groups of individuals. However, the study found the impact was not significant for some sub-groups, and for some ALPs the impact was negative. The final chapter summarizesthe general trends in findings on the various outcome measures across demographic and regional subgroups.Environmental Economics&Policies,Poverty Impact Evaluation,ICT Policy and Strategies,Health Monitoring&Evaluation,Poverty Monitoring&Analysis

Individual strategies of aggressive and non-aggressive male mice in encounters with trained aggressive residents

To determine whether individual differences in offensive behaviour are related to differences in defensive behaviour, the responses of male wild house mice, Mus domesticus, of an aggressive and a non-aggressive line to defeat by physically stronger residents were analysed. Individuals of the aggressive line engaged in more flight behaviour, whereas the males of the non-aggressive line predominantly showed immobility. The higher flight tendency of the aggressive intruders provoked more attacks by the resident, resulting in more fighting between the resident and an aggressive male than between the resident and a non-aggressive intruder. However, if offered an opportunity to escape from the home-cage of the resident, aggressive males more readily made use of it than non-aggressive intruders. Differences between aggressive and non-aggressive male mice are interpreted in terms of fundamentally different behavioural strategies adopted in response to social interaction. The response of aggressive males can be characterized as an active behavioural strategy by which they tend to determine actively their social situation. In contrast, the prevailing lack of overt attempts to manipulate the situation by the non-aggressive mice points to passive confrontation, in an offensive as well as in a defensive context.
