This chapter suggests that delinquency conceals two distinct categories of individuals, each with a unique natural history and etiology: A small group engages in antisocial behavior of one sort or another at every life stage, whereas a larger group is antisocial only during adolescence. According to the theory of life-course-persistent antisocial behavior, children's neuropsychological problems interact cumulatively with their criminogenic environments across development, culminating m a pathological personality. According to the theory of adolescence-limited antisocial behavior, a contemporary maturity gap encourages teens to mimic antisocial behavior in ways that are normative and adjustive. There are marked individual differences in the stability of antisocial behavior. The chapter reviews the mysterious relationship between age and antisocial behavior. Some youths who refrain from antisocial behavior may, for some reason, not sense the maturity gap and therefore lack the hypothesized motivation for experimenting with crime.

Adolescence-limited and life-course-persistent antisocial behavior: A developmental taxonomy.

It is a daunting honor to deliver the inaugural Pool Lecture. Ithiel de Sola Pool was a brilliant, broad-gauged scholar whose interests ranged from the Nazi elite to direct satellite broadcasting, from the first rigorous computer simulation of electoral behavior to the development of network theory, from which he invented "small world" research. He helped found the field of political communications. A graduate of the University of Chicago's political science department during its classic golden age, and first chair of the MIT political science department, Pool must also have been a remarkable teacher, for his students continue to contribute to our understanding of technology, communications, and political behavior. When I accepted this honor, I did not guess how close my own inquiry would lead me to Pool's own professional turf. I shall return to the contemporary relevance of Pool's insights at the conclusion of this talk.

Tuning In, Tuning Out: The Strange Disappearance of Social Capital in America

The pioneering longitudinal studies of child development (all launched in the 1920s and 1930s) were extended well beyond childhood Indeed, they eventually followed their young study members up to the middle years and later life In doing so, they generated issues that could not be addressed satisfactorily by available theories These include the recognition that individual lives are influenced by their ever-changing historical context, that the study of human lives calls for new ways of thinking about their pattern and dynamic, and that concepts of human development should apply to processes across the life span Life course theory has evolved since the 1960s through programmatic efforts to address such issues

The life course as developmental theory.

Today, the life course perspective is perhaps the pre-eminent theoretical orientation in the study of lives, but this has not always been the case. The life histories and future trajectories of individuals and groups were largely neglected by early sociological research. In the pioneering study, The Polish Peasant in Europe and America (1918-1920), W. I. Thomas (with Florian Znaniecki) first made use of such histories and trajectories and argued strongly that they be investigated more fully by sociologists. By the mid-1920s, Thomas was emphasizing the vital need for a “longitudinal approach to life history” using life record data (Volkart, 1951, p. 593). He advocated that studies investigate “many types of individuals with regard to their experiences and various past periods of life in different situations” and follow “groups of individuals into the future, getting a continuous record of experiences as they occur.” Though this advice went unheeded for decades, Thomas’s early recommendations anticipated study of the life course and longitudinal research that has become such a central part of modern sociology and other disciplines.

The Emergence and Development of Life Course Theory

The life course has emerged over the past 30 years as a major research paradigm. Distinctive themes include the relation between human lives and a changing society, the timing of lives, linked or interdependent lives, and human agency. Two lines of research converged in the formation of this paradigm during the 1960s; one was associated with an older «social relationship» tradition that featured intergenerational studies, and the other with more contemporary thinking about age. The emergence of a life course paradigm has been coupled with a notable decline in socialization as a research framework and with its incorporation by other theories

Social Change and Transitions to Adulthood in Historical Perspective

The Economic Basis of Ethnic Solidarity: Small Business in the Japanese American Community.

Bonacich and Modell explore class and ethnic behavior as reflected in the history of Japanese Americans in the Unites States. They demonstrate that involvement in certain types of self-consciously ethnic business structures supports the development and maintenance of Japanese American ethnic solidarity. The authors question the idea of ethnicity as a natural or primordial bond; they accept that ethnicity reflects social and political decisions; ethnic solidarity and antagonisms are socially constructed. Moreover, economic factors play a great role in maintenance or dissolution of ethnic bonds, and ethnic groups often function as economic-interest groups; when they no longer do so, they dissolve. Participation in wider society and professions diminishes such ethnicity. The middleman-minority thesis is used to interpret the experience of pre- and post-war Japanese Americans. The model comprises three traits: social and economic characteristics and society reactions. This study emphasizes the importance of a concentration in trade for creation and perpetuation of ethnicity. The middleman-minority model applies best to the first (Issei) generation of Japanese Americans. This generation had a peculiar economic position consisting of family-centered, non-contractual oriented firms doing business (primarily agricultural related) in the midst of a capitalist economy. Owners of these ethnic firms faced open hostility and discrimination, which drove them to develop and preserve their own distinctive ethnic associations and outlook. Characteristic features of Japanese American small businesses are identified. Using the structural framework of the "middleman minority," the authors explain the decreasing ethnic identity among second generation Japanese Americans in terms of the decreasing importance of small business as an economic base for the group, as members of this generation tended to move out into the professions. Using data from the Japanese American Research Project, the researcj examines the postwar development of this ethnic group to see to what degree pre-war economic forms have been reestablished among the second generation of Japanese Americans and the implications for their internal social organization and integration with the outside community. The pre-war ethnic economy was most revived by the oldest Japanese Americans. A division was found in the second (Nisei) generation, who are divided in economic orientation between small business and the professions. Degree of Nisei ethnicity and education are strongly related to birth date. The more educated Nisei moved into professions. Three important aspects of ethnic community are examined for the mid-1960s. Close family and kin relationships, and strong formal and informal ethnic associations, support and are supported by the middleman-minority ethnic economy. There is only a weak, but positive relationship between participation in small business and ethnic socialization and values; the relation is stronger for religion. The Sansei (children of the Nisei) show an even greater shift toward the professions than their parents. The study strongly departs from the "success story" or "model minority" approach of other ethnic research. Concludes that ethnic solidarity is a historical phenomenon; when ethnic minorities become like the majority economically, preserving their distinctiveness is difficult. (TNM)
