Objectives:

The processes driving gang entry and disengagement are central to classic and contemporary criminological research on gang involvement. Yet, the role of delinquent peer friendship networks in contouring gang membership has driven much of criminological research, with little empirical research devoted to understanding sibling influences on the gang career.

Method:

The study uses the National Longitudinal Survey of Youth 1997 to examine the transmission of gang membership among similar-aged siblings. These data offer the opportunity to use siblings’ self-report of gang involvement as a determinant of focal youths’ self-report of gang involvement while treating gang entry, persistence, and exit (and reentry) as unique transitions with potentially asymmetric determinants.

Results:

Results from the event history models indicate that gang involved siblings increase the hazard of entry and re-entry into the gang but have little influence on exit decisions. Sibling configurations with respect to sex and age-order further conditions these relations, with brothers and older siblings most influential.

Conclusion:

Ties to siblings serve as a salient and intimate type of social tie with siblings serving multiplex roles in each other’s lives. Findings lend additional insight on crime concentration in family networks and advance our understanding of continuity and change in gang involvement

帮派参与的兄弟姐妹传播

目标：

驱动犯罪团伙进入和脱离接触的过程是有关犯罪团伙参与的经典和当代犯罪学研究的核心。然而，不良同伴友谊网络在勾勒帮派成员身份方面的作用推动了许多犯罪学研究，很少有经验研究致力于了解兄弟姐妹对帮派职业的影响。

方法：

该研究使用《 1997年全国青年纵向调查》研究了同龄兄弟姐妹中帮派成员的传播情况。这些数据提供了一个机会，可以利用兄弟姐妹的帮派自我报告作为焦点青年的帮派自我报告的决定因素，同时将帮派的进入，持续性和退出（和再进入）视为具有潜在不对称决定因素的独特转变。

结果：

事件历史模型的结果表明，涉及帮派的帮派成员增加了进入帮派和再次进入帮派的危险，但对退出决策的影响很小。在性别和年龄顺序方面的兄弟姐妹结构进一步制约了这些关系，其中兄弟姐妹和年长的兄弟姐妹最有影响力。

结论：

与同胞的联系是显着和亲密的社会联系，同胞在彼此的生活中扮演着多重角色。调查结果使人们对家庭网络中的犯罪集中度有了更多了解，并加深了我们对犯罪团伙参与的连续性和变化的理解
