Policy research between the accumulation and implementation of knowledge

An important issue in the development of the field of applied research methodology is the increasing diversity of research questions, methodologies, and types of utilization. This is reflected in the fact that policy research is directed toward the analysis of social problems as well as designing and implementing policy strategies. In this context, different types of knowledge are produced in policy research (e.g., problem diagnosis, evaluation research, futures research). Moreover, policy research employs both qualitative and quantitative scientific approaches, as well as different implementation strategies of knowledge utilization. This article provides an overview of the most important developments in this area in The Netherlands during the past decade.

The knowledge and use of quantitative research by pastoral counselors

This study investigated the degree of training, experience and interest in quantitative research among pastoral counselors. It was found that a little over half of the subjects had had at least one statistics course and thought that research was valuable. However, less than 6% had ever published research and only one subject (less than 1%) had published more than two quantitative articles. This suggests there is a research vacuum in the field of pastoral counseling. There is no scientific core of scholars publishing a systematic program of research. Recommendations for ways to involve pastoral counselors more actively in research are made.New Perspectives, Owings Mills, MD.     

Recalibrating color categories using world knowledge

ABSTRACT— When the perceptual system uses color to facilitate object recognition, it must solve the color-constancy problem: The light an object reflects to an observer's eyes confounds properties of the source of the illumination with the surface reflectance of the object. Information from the visual scene ( bottom-up information) is insufficient to solve this problem. We show that observers use world knowledge about objects and their prototypical colors as a source of top-down information to improve color constancy. Specifically, observers use world knowledge to recalibrate their color categories. Our results also suggest that similar effects previously observed in language perception are the consequence of a general perceptual process.     

Characterizing sequence knowledge using online measures and hidden Markov models

What knowledge do subjects acquire in sequence-learning experiments? How can they express that knowledge? In two sequence-learning experiments, we studied the acquisition of knowledge of complex probabilistic sequences. Using a novel experimental paradigm, we were able to compare reaction time and generation measures of sequence knowledge online. Hidden Markov models were introduced as a novel way of analyzing generation data that allowed for a characterization of sequence knowledge in terms of the grammar that was used to generate the stimulus material. The results indicated a strong correlation between the decrease in reaction times and an increase in generation performance. This pattern of results is consistent with a common knowledge base for improvement on both measures. On a more detailed level, the results indicate that at the start of training, generation performance and reaction times are uncorrelated and that this correlation increases with training.     

Fostering integrity in research: Definitions, current knowledge, and future directions

Over the last 25 years, a small but growing body of research on research behavior has slowly provided a more complete and critical understanding of research practices, particularly in the biomedical and behavioral sciences. The results of this research suggest that some earlier assumptions about irresponsible conduct are not reliable, leading to the conclusion that there is a need to change the way we think about and regulate research behavior. This paper begins with suggestions for more precise definitions of the terms "responsible conduct of research," "research ethics," and "research integrity." It then summarizes the findings presented in some of the more important studies of research behavior, looking first at levels of occurrence and then impact. Based on this summary, the paper concludes with general observations about priorities and recommendations for steps to improve the effectiveness of efforts to respond to misconduct and foster higher standards for integrity in research.     

Measuring unconscious knowledge: distinguishing structural knowledge and judgment knowledge

This paper investigates the dissociation between conscious and unconscious knowledge in an implicit learning paradigm. Two experiments employing the artificial grammar learning task explored the acquisition of unconscious and conscious knowledge of structure (structural knowledge). Structural knowledge was contrasted to knowledge of whether an item has that structure (judgment knowledge). For both structural and judgment knowledge, conscious awareness was assessed using subjective measures. It was found that unconscious structural knowledge could lead to both conscious and unconscious judgment knowledge. When structural knowledge was unconscious, there was no tendency for judgment knowledge to become more conscious over time. Furthermore, conscious rather than unconscious structural knowledge produced more consistent errors in judgments, was facilitated by instructions to search for rules, and after such instructions was harmed by a secondary task. The dissociations validate the use of these subjective measures of conscious awareness.     

Children's capacity to agree to psychological research: knowledge of risks and benefits and voluntariness

A series of studies investigated the capacity of children between the ages of 7 and 12 to give free and informed consent to participation in psychological research. Children were reasonably accurate in describing the purpose of studies, but many did not understand the possible benefits or especially the possible risks of participating. In several studies children's consent was not affected by the knowledge that their parents had given their permission or by the parents saying that they would not be upset if the children refused. In contrast, other studies found that children were much more likely to stop their participation if the experimenter said explicitly that she would not be upset if they stopped. We suggest that experimenters should pay more attention to describing the possible risks and benefits of participation in research, and that they should also make it clearer to children that they are free to stop once they have begun.     

Forbidden knowledge. A case study with commentaries exploring ethical issues and genetic research

This case is part of a series of case studies used as an exercise within a program on research ethics education. The case involves research on genetic birth defects in a culturally distinct, closed religious community in which elders speak for the community. The case raises ethical issues of informed consent in such a setting; of collaboration with the community; of conflicts between the researchers' responsibilities to the community as a whole and to individual subjects; of the impact of the researcher's findings on the practices and values of the community and issues regarding how the researchers share findings with subjects and how the findings are stored.     

Language knowledge and event knowledge in language use

This paper examines how semantic knowledge is used in language comprehension and in making judgments about events in the world. We contrast knowledge gleaned from prior language experience (“language knowledge”) and knowledge coming from prior experience with the world (“world knowledge”). In two corpus analyses, we show that previous research linking verb aspect and event representations have confounded language and world knowledge. Then, using carefully chosen stimuli that remove this confound, we performed four experiments that manipulated the degree to which language knowledge or world knowledge should be salient and relevant to performing a task, finding in each case that participants use the type of knowledge most appropriate to the task. These results provide evidence for a highly context-sensitive and interactionist perspective on how semantic knowledge is represented and used during language processing.     

Advancing knowledge about delinquency and crime: The need for a coordinated program of longitudinal research

Past research on delinquency and crime has provided convincing data about correlates but not about causes, because it has been largely cross-sectional in design. Whereas cross-sectional research focuses on variations between subjects, longitudinal research can provide information about changes within subjects, which are more important for causes, prevention, and treatment. Many of the most important results in criminology have been obtained in longitudinal or experimental studies, and the major studies of these types are reviewed here. It is now desirable to combine the two methods in a new coordinated program of longitudinal studies including experimental interventions or quasi-experimental analyses. Such projects could study several overlapping cohorts, extend from birth to adulthood, have frequent data collection, and obtain data from a variety of sources about many different types of antisocial behavior.     

Disseminating a Parenting Intervention in the Community: Experiences from a Multi-Site Evaluation

Circle of Security-Parenting (COS-P) is a widely used parenting intervention that is gaining popularity globally as it is currently being delivered across several continents. Despite the global uptake of COS-P, there is limited research on its effectiveness with considerable variability in its delivery. Here we present a multi-site evaluation of the group delivery of COS-P to under-resourced mothers (n?=?131 enrolled) in an urban community as facilitated by community-based providers (n?=?12) from community sites (n?=?6) that provide maternal and child services. The feasibility and acceptability of delivering COS-P in the community are highlighted as well as characteristics of sites and providers as they relate to implementation efforts, and pre and post-intervention data examining COS-P and maternal caregiving functioning (i.e., depressive symptoms, reflective functioning) are also included. Several service delivery barriers were encountered at agency, provider and participant levels that created obstacles for program dissemination, participant retention and evaluation. Nonetheless, COS-P was successfully delivered in the community when sites embedded the program within their existing infrastructure and had the internal capacity for delivery, participant recruitment, supervision, and community presence. Mothers who participated in COS-P also reported fewer depressive symptoms following the intervention (n?=?25). This multi-site implementation and evaluation study has important implications for the delivery of parenting services to under-resourced communities globally. Implications for future research and service delivery are discussed.     

Meta-planning: Representing and using knowledge about planning in problem solving and natural language understanding

This paper is concerned with those elements of planning knowledge that are common to both understanding someone else's plan and creating a plan for one's own use. This planning knowledge can be divided into two bodies: Knowledge about the world, and knowledge about the planning process itself. Our interest here is primarily with the latter corpus. The central thesis is that much of the knowledge about the planning process itself can be formulated in terms of higher-level goals and plans called meta-goals and meta-plans. These entities can then be used by the same understanding and planning mechanisms that process ordinary goals and plans. However, the meta-planning knowledge now enables these mechanisms to handle much more complicated situations in a uniform manner. Systems based on meta-planning would have a number of advantages over existing problem solving and understanding systems. The same knowledge could be shared by both a planner and understander, and both would be able to handle complex situations elegantly. In addition, in planning, the use of meta-planning has several advantages over more traditional methods involving constraints or critics. Meta-planning allows the full power of a problem solver to be applied to situations that are generally amenable only to special purpose processing. In addition, meta-planning facilitates the representation of some situations that are difficult to express otherwise. We have begun to introduce meta-planning knowledge into two systems: PAM, a story understanding program, and PANDORA, a problem solving and plannin?g system.
