Adolescent Substance Use and Marital Status in Adulthood

Researchers have noted that substance use in the adolescent years is associated with a variety of consequences. The majority of studies have focused on relatively short-term consequences of substance use. Using data from the 2007 National Survey on Drug Use and Health, this study examines how early substance use and current substance use affect individuals’ eventual marital status. Higher levels of substance use in the adult years are shown to be relatively deleterious to both women’s and men’s chances of marriage. However, initial cigarette use in the adolescent years is shown to enhance adults’ likelihood of marriage, whereas adolescent marijuana use substantially reduces the chances of marriage. Interestingly, early alcohol use decreases women’s chances of becoming married yet increases the chances for men. Similarly, early alcohol use was associated with a greater risk of divorce. Overall, the results point to the intricate nature of early substance use and the long-term consequences thereof. The results are discussed within a framework of precocious development theory.     

Stakeholder strategies for the physician executive.

If physician executives are to be effective in confronting the environmental turbulence and uncertainty facing their organizations, they must effectively manage their stakeholders. This article extends the stakeholder approach described in the May-June 1989 issue of Physician Executive as a tool for the physician executive in the development of practical strategies to cope with turbulence and uncertainty. We suggest four generic strategies physician executives can use: involve supportive stakeholders, monitor marginal stakeholders, defend against nonsupportive stakeholders, and collaborate with mixed-blessing stakeholders. As an overarching strategy, a physician executive should try to change the organization's relationships with a stakeholder from a less favorable category to a more favorable one. The stakeholder can then be managed using the generic strategy most appropriate for the category.     

The Student Watershed Research Project (SWRP): collecting watershed data for use by resource management agencies

From 1992 to 1994, Saturday Academy and the Oregon Graduate Institute of Science and Technology instituted the pilot phase of a long-term monitoring program called the Student Watershed Research Project (SWRP). The SWRP program was developed to create and maintain collaboration among eighth through twelfth grade teachers and students, scientists, businesses, governmental agencies, and community members which would couple environmental education with the collection of high quality, reproducible watershed health data.The original authors of this paper set out to evaluate the impacts of the SWRP program in terms of changes in educational attitudes of participants and collection of accurate data. Findings demonstrate that assuring accuracy of student collected data was challenging, that teachers and students benefited greatly from a hands-on research approach to science education, and that such an approach would be difficult without the support of a program like SWRP.The SWRP program is entering its seventh year in the Portland, Oregon and Vancouver, Washington metropolitan areas with approximately half of the pilot phase participants still involved. A Quality Assurance Project Plan has been developed to assure data accuracy. Evaluation student science education attitudes documents improved results on a yearly basis.     

Negotiating with interactive scenarios and strategies

Physician executives need to negotiate effectively with a wide range of parties. In those negotiations, they should consider the relative importance of both substantive and relationship outcomes in selecting initial negotiation strategies. Of course, these strategies may or may not be successful, depending on the strategies used by the other party. Hence, the physician executive must consider the other party's strategy and how it and his or her initial strategy are likely to interact both before and during negotiations.     

Ecological Risks and Community Perceptions of Fairness and Justice: A Cross-Cultural Model

Intergenerational justice is implicit in international commitments to sustainability. If ecological, economic, and social components of sustainability are to be achieved, there is a necessity for intergenerational justice considerations to be included in decision making. The present generation's risk judgments should include consideration of the possible outcomes for their children. But intergenerational issues cannot be considered in isolation from other current risk and fairness concerns. This article reports on a community-based integrative model that describes justice and other attitudes and motivations that determine community and individual proenvironmental behavior in two nations: Germany and Australia. This model can account for a considerable amount of the variance in political compliance as well as various proenvironmental behaviors. Group or individual self-interests have nearly no effects on global protective behavior. It is shown that universal as well as contextual principles, including distributive (within or between generations), procedural, and interactive justice, play a crucial role in fairness judgments. Other principles are also taken into account, such as efficiency, environmental rights, and rights to economic welfare. The results are discussed in relation to the importance of complex community fairness judgments in predicting and evaluating acceptance of political decisions, and for promoting proenvironmental behavior.     

A Simulation Study of Sequencing Rules in a Kanban-Controlled Flow Shop*

This paper addresses the problem of sequencing in decentralized kanban-controlled flow shops. The kanban production control system considered uses two card types and a constant withdrawal period. The flow shops are decentralized in the sense that sequencing decisions are made at the local workstation level rather than by a centralized scheduling system. Further, there are no material requirements planning (MRP)-generated due dates available to drive dispatching rules such as earliest due date, slack, and critical ratio. Local sequencing rules suitable for the decentralized kanban production-control environment are proposed and tested in a simulation experiment. These rules are designed so that they can be implemented with only the information available at the workstation level. Example sequencing problems are used to show why the shortest processing time rule minimizes neither average work-in-process inventory nor average finished-goods withdrawal kanban waiting time. Further, it is shown how work station supervisors can use the withdrawal period, in addition to the number of kanbans, to manage work-in-process inventories.     

Simulation Tests of FCFS and SPT Sequencing in Kanban Systems

One of the basic tenets of scheduling theory is that the SPT sequencing rule maximizes average production rates and minimizes average in-process inventories. This paper shows that on single-card kanban-controlled lines FCFS often has greater average production rates than SPT. Further, the performance of SPT declines relative to FCFS for larger queue capacities and less frequent material handling. Results for the single-card system are also compared to those of Berkley and Kiran [1]. In that article it was shown that for two-card systems with periodic material handling, SPT has larger average inventories than FCFS. This paper shows that these surprising results can be attributed to Berkley and Kiran's material-handling mechanism.     

Parents' Affect,Adolescent Cognitive Representations,and Adolescent Social Development

Prior research regarding the role of parent‐child relationships in children's social development generally has been limited to concurrent or short‐term longitudinal data and has focused primarily on mothers' influence in the early or middle childhood years. Using a multimethod, multiinformant design, the present study extends previous findings by examining whether maternal and paternal affect predicted adolescent social behavior and peer acceptance 2 years later. Both maternal and paternal affect had significant direct and indirect effects (via adolescent cognitive representations of parents) on adolescent negative social behavior as reported by siblings, which in turn predicted decreased peer acceptance as rated by teachers. Findings suggest that both mothers and fathers shape adolescent social development and attest to the importance of exploring multiple pathways that may account for continuity in parent‐child and peer relationships.
