Agglomeration Effects: Productivity of the Informal Sector in Vietnam

This paper investigates agglomeration externalities on the productivity of informal household businesses in Vietnam. Although the paper finds heterogeneous impacts of agglomeration on the productivity of informal firms between urban and rural settings and across industries, it is found that technology transfers are not an agglomerative force for the informal sector of Vietnam. The disaggregation of local scale externalities into city types reveals that the highest developed cities in Vietnam may either be low-quality agglomeration or go beyond their optimal scale for the informal sector in some industries.     

Political Participation and Civic Courage: The Negative Effect of Transparency on Making Small Campaign Contributions

This study assesses whether public disclosure of campaign contributions affects citizens’ willingness to give money to candidates. In the American states, campaign finance laws require disclosure of private information for contributors at relatively low thresholds ranging from $1 to $300. The Internet has made it relatively easy to publicize such information in a way that changes the social context for political participation. Drawing on social influence theory, the analysis suggests that citizens are sensitive to divulging private information, especially those who are surrounded by people with different political views. Using experimental data from the 2011 Cooperative Congressional Election Studies, it demonstrates how individuals refrain from making small campaign contributions or reduce their donations to avoid disclosing their identities. The conclusion discusses the implications of transparency laws for political participation, especially for small donors.     

Does This Make Me Look Fat? Peer Crowd and Peer Contributions to Adolescent Girls’ Weight Control Behaviors

Based on the Theory of Reasoned Action, this study evaluated a “socialization” model linking girls’ peer crowd affiliations (e.g., Jocks, Populars) with their own weight concern, perceived peer weight norms, and weight control behaviors. An alternative “selection” model was also evaluated. Girls (N = 236; M age = 15.95 years) from diverse ethnic backgrounds completed surveys assessing peer crowd affiliation, their own concern with weight, perceptions of peers’ concern with weight, and weight control behaviors. Models were evaluated using SEM. The socialization model demonstrated good fit; the alternative selection model did not. Specifically, girls’ level of identification with certain peer crowds (Jocks, Burnouts, Alternatives) was associated with girls’ reported own concern and perceived peer concern with weight. Additionally, girls’ own concern and peer norms were related independently to girls’ weight control behaviors. Findings suggest that peer crowds and girls’ own and peer weight norms may be important targets of prevention efforts.

Language and education laws in multi-ethnic de facto states: the cases of Abkhazia and Transnistria

Even after the conflicts of the early 1990s that brought them to their de facto independence, both Abkhazia and Transnistria remained strongly multi-ethnic. In both territories, no single ethnic group is an absolute majority and Russian is the language that is mostly spoken on the streets of Sukhumi and Tiraspol. Legislators of both entities felt the need to deal with multi-ethnicity and multilingualism, including in their constitutions, in laws related to education, or more directly with specific language laws (1992 law “On languages” in Transnistria; 2007 law “On the state language in Abkhazia”). The protection of linguistic rights that is formally part of the legislation of both territories finds limitations in practice. The language of education has proved to be particularly contentious, in particular for Moldovan/Romanian language schools in Transnistria and Georgian language schools in Abkhazia. Why are language laws in Abkhazia and Transnistria so different, in spite of the fact that they are both post-Soviet, multi-ethnic territories that became de facto independent in the early 1990s? The different approaches found in Abkhazia and Transnistria represent remarkable examples of language legislation as a tool for nation-building in ethnically heterogeneous territories.     

Peer Victimization and Social Anxiety in Adolescents: Prospective and Reciprocal Relationships

This study used a 2-month prospective research design to examine the bi-directional interplay between peer victimization and social anxiety among adolescents. Participants included 228 adolescents (58% female) in grades 10–12. Three types of peer victimization were examined: overt (physical aggression or verbal threats), relational (malicious manipulation of a relationship, such as by friendship withdrawal), and reputational (damaging another’s peer relationships, such as through rumor spreading). Adolescents’ self-reported feelings of social anxiety and peer victimization experiences were assessed at two time points, in November and January of the same school year. Peer victimization was strongly related to adolescents’ social anxiety, and relational victimization explained additional unique variance. Moreover, peer victimization was both a predictor and consequence of social anxiety over time, with the most robust results found for relational victimization. Limited support was obtained for gender as a moderating variable. Findings highlight the deleterious effects of peer victimization, especially relational victimization, and suggest avenues for future research and clinical intervention for adolescents experiencing such victimization.

Do citizens hold mayors accountable for local conditions? Evidence from Italian municipalities

Using data on 75 big Italian municipalities between 2010 and 2015, this paper looks at the extent to which citizens’ evaluations of mayors are responsive to changes in local performance indicators. While local economic and crime measures are found not be associated with mayoral approval ratings, there is a correlation between mayors’ popularity and indicators for local public transportation and air quality. Mayors of municipalities where more individuals use public transport and where there is less polluted air enjoy higher approval ratings. Additional analysis shows that this result is driven by very big municipalities (with a population over 500,000) that are more likely to be exposed to high levels of traffic congestion and pollution.     

Models of university technology transfer: analyses and policies

Recent data on European countries show that innovation leaders perform better than economies with low levels of innovation investment and institutions that do not favor knowledge and technology transfer activities. This result confirms that to achieve a high level of performance, countries need a balanced innovation system performing well across all dimensions. More interestingly, the two most important indicators that have been driving increases in performance include new doctoral graduates and international scientific co-publications, that is, two channels of knowledge transfer from universities to firms. This special issue of the Journal of Technology Transfer is dedicated to the discussion of models of university technology transfer, mostly from a European perspective.
