This article explores the diverse semiotic landscapes which may be experienced as a consequence of apparently mundane rides taken upon the Shanghai metro. I first present, and then untangle, the ideological discourses that form, clash and, at times, collapse during these journeys. In order to elaborate upon the composition of these signs, they are viewed from multiple perspectives, although significant reference is made to Roland Barthes’ punctum/studium dialectic. These signs are not only read as manifestations of robust ideology but also as indeterminate, and fragile. This article is also concerned with pragmatics on the Shanghai metro, or the relationships between people and signs, and illustrates how passengers perform within this semiotically charged environment in ways which, sometimes, undo, or subvert, urban rationality. Although this article specifically focuses upon the Shanghai metro, and one particular route in its parliament of lines, it is intended these observations not only inform but also are informed by accounts of social spaces beyond these limits.  相似文献

Government transparency continues to challenge existing frameworks for understanding organizational performance. Transparency has proven difficult to measure and results assessing its impacts are mixed. This article sets forward a model of performance-based accountability in open government initiatives. Data come from the Open Government Partnership’s (OGP) database of over 1,000 transparency initiatives across 50 countries in 2013. Ordered logistic regression estimates the effect of management practices on three different measures of transparency performance, and the results broadly support the model. Expert interviews from two country cases offer insight into how performance management is used in the context of transparency reforms.  相似文献

An economic impact snapshot of foreign and domestic enterprises from the functional economic areas of Guinea-Bissau showed that not all micro and small enterprises (MSEs) are local, and not all outside investment is large scale. We find that South–South entrepreneurship has prospects to improve livelihoods as drivers of economic growth and development in a low-income economy. While political instability and a lack of resources remain as barriers to solvency for both domestic and foreign investors in the global periphery, as opportunities and effective business strategies are fostered, improved socio-economic integration and development results.  相似文献

The relationship between victimization and offending has been shown consistently across different samples, settings, and crime types. This study uses data from the Pathways to Desistance Study to examine dual trajectories of offending between the ages of 15 and 24 in a sample of male felony offenders. The dual trajectory models demonstrate substantial convergence in victimization and offending. And while there are sizable numbers of youth who continue to be victimized, but desist or decrease in their offending behaviors, very few youth continue to offend in the absence of continued victimization. This study also proposes and tests three criminological theories that have been employed as explanations for the victim-offender overlap—low self-control, lifestyles/routine activities, and street-code attitudes. The logistic regression results indicate that involvement in risky and/or unstructured, unsupervised activities is a key correlate of the victim-offender overlap. The strength of the relationship between routine activity variables and the victim-offender overlap supports the provision of structured, supervised activities for youth and young adults as a way of preventing future victimization and offending, particularly among youth who have high exposure to violence.  相似文献

The current study modeled trajectories of substance use from ages 15 to 20 among 1,095 male serious juvenile offenders (M age = 16.54; 42% African-American, 34% Latino, 20% European-American, and 4% other ethnic/racial backgrounds) and prospectively predicted trajectories from risk and protective factors before and after controlling for time spent in a supervised setting. Results indicated that supervised time suppressed age-related growth in substance use. Trajectories of offenders with no supervised time and low levels of supervised time increased in substance use across age, whereas offenders with high levels of supervised time showed no growth. Almost all risk and protective factors had effects on initial substance use but only adolescent history of substance use, impulse control, and psychosocial maturity had an effect on change in substance use over time. Findings highlight the importance of formal sanctions and interventions superimposed on normal developmental processes in understanding trajectories of substance use among serious juvenile offenders.

Exposure to violence is a serious public health concern that compromises adolescents by affecting their behavior and psychological well-being. The current study advances knowledge about the consequences of exposure to violence in adolescence by applying a life course perspective to evaluate the developmental implications of adolescents’ exposure to violence. In particular, drawing on a sample of 11,949 school-aged adolescents in the U.S., we examine whether exposure to violence in adolescence is associated with precocious role exits that some adolescents experience. Exposure to violence is conceptualized as including both direct (i.e., experiencing physical victimization) and indirect exposure (i.e., witnessing others’ victimization). Three types of direct exposure to violence are examined: street, intimate partner, and family victimization, as well as four types of indirect exposure including: street, peer, and school violence as well as exposure to family/friend suicide. Using three waves of longitudinal data from the Add Health Study, we find that exposure to violence is associated with greater risks of running away from home, dropping out of high school, having a child, attempting suicide, and coming into contact with the criminal justice system in later adolescence. In addition, risks depend upon the relational context in which the exposure to violence occurred, risks increase with greater exposure to violence, and risks are, for the most part, highest for those youth exposed to both indirect and direct violence in adolescence.
