Means–end chains as goal hierarchies

Abstract: A means–end chain (MEC) has been defined as a hierarchy of goals that represents potential identities of the actions necessary for the person to reach his or her goal. Goals as ends in MECs can be grouped into three levels: action goals (concerned with the act itself), outcome goals (immediate effects of actions), and consequences (indirect effects stemming from outcomes). An action unit (AU) is defined as a planned sequence of acts directed toward goal achievement. AUs may be part or all of a MEC, thus the highest goal in a MEC may not be what the consumer has in mind when making a purchase or consumption decision. Data are presented that suggest that laddering takes respondents beyond the intended goals of their initial actions or choice. Goals beyond AU's which are part of a MEC may represent the underlying reasons why we strive for the goals we do. This seems to be one useful way to differentiate goals from values. Goals are what we want; values are why we want them. © 1997 John Wiley & Sons, Inc.

The Prevention of Childhood Sexual Abuse

Abstract: Summary David Finkelhor examines initiatives to prevent child sexual abuse, which have focused on two primary strategies—offender management and school-based educational programs. Recent major offender managment initiatives have included registering sex offenders, notifying communities about their presence, conducting background employment checks, controlling where offenders can live, and imposing longer prison sentences. Although these initiatives win approval from both the public and policy makers, little evidence exists that they are effective in preventing sexual abuse. Moreover, these initiatives, cautions Finkelhor, are based on an overly stereotyped characterization of sexual abusers as pedophiles, guileful strangers who prey on children in public and other easy-access environments and who are at high risk to re-offend once caught. In reality the population is much more diverse. Most sexual abusers are not strangers or pedophiles; many (about a third) are themselves juveniles. Many have relatively low risks for re-offending once caught. Perhaps the most serious shortcoming to offender management as a prevention strategy, Finkelhor argues, is that only a small percentage of new offenders have a prior sex offense record that would have involved them in the management system. He recommends using law enforcement resources to catch more undetected offenders and concentrating intensive management efforts on those at highest risk to re-offend. Finkelhor explains that school-based educational programs teach children such skills as how to identify dangerous situations, refuse an abuser’s approach, break off an interaction, and summon help. The programs also aim to promote disclosure, reduce self-blame, and mobilize bystanders. Considerable evaluation research exists about these programs, suggesting that they achieve certain of their goals. Research shows, for example, that young people can and do acquire the concepts. The programs may promote disclosure and help children not to blame themselves. But studies are inconclusive about whether education programs reduce victimization. Finkelhor urges further research and development of this approach, in particular efforts to integrate it into comprehensive health and safety promotion curricula.

Direct evidence for magnetic reconnection in the solar wind near 1 AU

Abstract: [1] We have obtained direct evidence for local magnetic reconnection in the solar wind using solar wind plasma and magnetic field data obtained by the Advanced Composition Explorer (ACE). The prime evidence consists of accelerated ion flow observed within magnetic field reversal regions in the solar wind. Here we report such observations obtained in the interior of an interplanetary coronal mass ejection (ICME) or at the interface between two ICMEs on 23 November 1997 at a time when the magnetic field was stronger than usual. The observed plasma acceleration was consistent with the Walen relationship, which relates changes in flow velocity to density-weighted changes in the magnetic field vector. Pairs of proton beams having comparable densities and counterstreaming relative to one another along the magnetic field at a speed of ∼1.4VA, where VA was the local Alfven speed, were observed near the center of the accelerated flow event. We infer from the observations that quasi-stationary reconnection occurred sunward of the spacecraft and that the accelerated flow occurred within a Petschek-type reconnection exhaust region bounded by Alfven waves and having a cross section width of ∼4 × 105 km as it swept over ACE. The counterstreaming ion beams resulted from solar wind plasma entering the exhaust region from opposite directions along the reconnected magnetic field lines. We have identified a limited number (five) of other accelerated flow events in the ACE data that are remarkably similar to the 23 November 1997 event. All such events identified occurred at thin current sheets associated with moderate to large changes in magnetic field orientation (98°–162°) in plasmas characterized by low proton beta (0.01–0.15) and high Alfven speed (51–204 km/s). They also were all associated with ICMEs.

Collaboration and technology linkages: a strategic supplier typology

Abstract: This study uses frameworks from the strategic management and operations strategy literatures to explore the relationships among collaboration, technology, and innovation in small and medium-sized manufacturers. Statistical analysis of the responses of 200 New Hampshire manufacturing companies in four SIC code industries (fabricated metals, industrial equipment, electrical and electronic equipment, and instruments) leads to the development of a strategic supplier typology which is useful in explaining the differences in the composition and performance of various types of suppliers.
