The information age is upon us. In schools across the country, administrators are making important decisions about how best to employ computer technology. This case study of an expert educational administrator looks at computer use from a problem‐solving perspective, focusing on the relationship between how this school leader thinks about and acts on technological capacity. It examines the personal attributes and perceptions that underlie his effective application of technology and finds them interwoven with the same cognitive and behavior skills he employs across his problem solving. It explores the connections he makes between school and community and between administrative and instructional technology.

Recent experiments show that feedback transmission can mitigate opportunistic behavior in repeated social dilemmas. Two nonexcludable explanations have been investigated: strategic signaling and nonmonetary sanctioning. This literature builds on the intuition that under both partner matching (where the same groups of players interact many times) and stranger matching (where groups change continuously), feedback may work as a nonmonetary sanctioning device, but only the former also allows for strategic signaling. Empirical evidence on the two explanations is mixed. Moreover, the usual design may give rise to confounding matching protocol effects.

My experiment provides a novel empirical testbed for different channels by which feedback – costless disapproval points – may affect behavior in a repeated public goods game. In particular, it is based on a random matching scheme that neutralizes the confounding effects of different matching protocols on behavior.

The transmission of feedback is found to foster prosocial behavior. The data favor the nonmonetary sanctioning explanation rather than the signaling hypothesis.

This study provides a novel set of evidence that (i) communication may mitigate selfishness in social dilemmas and (ii) the source of this phenomenon may be linked to the emotional reaction that communication evokes in humans.

Civil society has emerged as a contested concept in development. Some observers claim that economic restructuring has eroded the political hegemony of authoritarian regimes and created a new space for autonomous associations. In Mexico, chronic economic crisis and economic adjustment policies generated widespread popular discontent in the 1980s. The authoritarian regime tried to channel popular dissatisfaction into the institutionalized political arena through a series of electoral reforms. Thus, economic liberalization in Mexico was paralleled by a slow and gradual process of liberalization of the Mexican political system. In the context of these economic and political changes, scholars have observed an awakened civil society in Mexico. They have chronicled the emergence of independent organizations of workers, peasants, and the urban poor. They have also documented new types of civic associations such as environmental groups, election‐watch groups, human rights organizations, debtors’ groups, and women’s movements. Numerous studies of social movements beginning in the 1980s appear to suggest the rise of civil society in the era of economic and political liberalization.

The object of this research is the reconstruction of the existing legal response by European Union states to the phenomenon of immigration. It seeks to analyse the process of conferral of protection.

One main dimension is selected and discussed: the case law of the national courts. The study focuses on the legal status of immigrants resulting from the intervention of these national courts.

The research shows that although the courts have conferred an increasing protection on immigrants, this has not challenged the fundamental principle of the sovereignty of the states to decide, according to their discretionary prerogatives, which immigrants are allowed to enter and stay in their territories. Notwithstanding the differences in the general constitutional and legal structures, the research also shows that the courts of the three countries considered – France, Germany and Spain – have progressively moved towards converging solutions in protecting immigrants.

The research contributes to a better understanding of the different legal orders analysed.
