The current study examined concurrent and longitudinal predictors of early adolescents’ involvement in Internet aggression. Cross-sectional results (N = 330; 57% female) showed that the likelihood of reporting Internet aggression was higher among youth who spent more time using Internet-based technologies to communicate with friends and who were themselves targets of Internet aggression. Offline relational aggression and beliefs supportive of relational and physical aggression also predicted concurrent involvement in Internet aggression. We used longitudinal data (N = 150; 51% female) to distinguish between youth who were aggressive in traditional contexts only (i.e., school) from those who were aggressive both online and offline. These results indicated that youth who were aggressive both online and offline were older at the initial assessment, were targets of Internet aggression, and held beliefs more supportive of relational aggression than youth who were aggressive offline only. Implications and directions for future research are discussed.  相似文献

The transition to high school has been identified as a potentially difficult time in adolescents’ lives. Reductions in both academic and social functioning often accompany this transition. While these effects have been documented in urban youth, the move to high school has not been extensively studied in rural minority youth. Toward that end, the academic grades and substance use in ninth grade of 447 (184 male and 263 female) African-American adolescents from two rural counties in a state in the deep South were examined in relation to configurations of adaptation from sixth through eighth grade. Results indicate that individual with consistently positive patterns across middle school had higher grades and lower rates of substance use compared to individuals with persistent difficulties or those that transitioned to problem behavior. Many individuals who improved in their patterns of adaptation had relatively high grades, but also rather high rates of substance use in the ninth grade. David B.

In this article I test two competing visions about how democracy produces responsive government. Electoral theories of democracy posit that elected governments are responsive to public demands because citizens are able to sanction bad politicians and select good ones. Participatory theories attribute responsiveness to a citizenry's ability to articulate demands and pressure government through a wider range of political action. I test hypotheses derived from these two approaches, using an original dataset that combines electoral, socioeconomic, and public-financial indicators for Mexico's 2,400 municipalities, from 1989 to 2000. The data show that electoral competition has no effect on municipal government performance. But the results are consistent with the hypothesis that nonelectoral participation causes improved performance. Thus, I suggest that the quality of municipal government in Mexico depends on an engaged citizenry and cooperation between political leaders and their constituents, rather than the threat of electoral punishment. I recommend that scholars broaden the study of government responsiveness to account for participatory strategies of political influence and critically assess the claims of those who would promote elections as a cure-all for poor democratic performance.  相似文献

Why does the influence of Congressional parties fluctuate over time? Building on prevailing answers, we develop a model, Strategic Party Government, which highlights the electoral motives of legislative parties and the strategic interaction between parties. We test this theory using the entire range of House and Senate party behavior from 1789 to 2000 and find that the strategic behavior of parties complements members' preferences as an explanation for variation in party influence. Specifically, the strongest predictors of one party's voting unity are the unity of the opposing party and the difference between the parties in the preceding year. Moreover, we find strong links between party behavior in Congress and electoral outcomes: an increase in partisan influence on legislative voting has adverse electoral costs, while winning contested votes has electoral benefits.  相似文献

It is widely recognized that interest groups affect both microeconomic and macroeconomic outcomes. However, few researchers have attempted to discern empirically the factors that contribute to interest group activity. This paper provides a test of several theories of group formation in a panel setting. A nation’s stability, socioeconomic development, political system, size, and diversity all appear to contribute to interest group formation, as predicted by theory.  相似文献

The index of socioeconomic and cultural diversity among theAmerican states formulated by John L. Sullivan for 1960 is recreatedfor 1980. Comparisons are made between the index for the twotime periods, and changes among the states are examined overtime. Significant differences continue to exist between northernand southern states, mainly because of cultural rather thansocioeconomic factors. The diversity index remains a relativelypowerful predictor of policy variation among the states and,as such, might be considered as a substitute for geographicregion in comparative state policy research.  相似文献
