PUBLIC POLICY AND POLITICAL CHOICE: A REVIEW ARTICLE

Abstract: In reviewing the literature on policy studies, as in studying policy making itself, what you see depends on where you look. Studies of public policy vary widely in forms, methods and rationale. This paper does not try to categorize and capture the spirit of all aspects of a diverse and burgeoning literature. Its focus is on a number of recent books that straddle broadly the categories of process and administrative studies. The questions addressed in the volumes discussed are about how institutions handle issues in public policy, their relevance to the actual content of policy, and the ways in which individuals and groups within them see and respond to opportunities for choice. Each book is concerned with questions of theory but the books do not, either singly or together, suggest a single compelling theory of institutions and policy processes. Indeed, considering their theoretical sophistication, one may doubt whether such a goal is practicable. The better the work done on policy studies the more open-ended theoretically the field seems to be.     

Latent-variable models in criminological research: Applications and a generalization of Joreskog's LISREL model

This paper examines issues in LISREL models involving latent, or unobserved, variables. We discuss estimating parameters in multiple-indicator models, various approaches to assessing goodness of fit, different types of linear measurement models, using LISREL to correct for attenuation in models involving single indicators with known reliabilities, and estimating parameters in structural equation models involving latent exogenous and endogenous variables. Finally, we present a generalization of the standard LISREL model which explicitly identifies implicit constraints on parameters in the standard LISREL model. We argue that the generalization can accommodate a wider range of models and provide additional diagnostic information on some assumptions in the standard LISREL model. By example, we show how the more general model can be estimated using Joreskog's LISREL program.     

Using brain MERMER testing to detect knowledge despite efforts to conceal

This experiment examined the accuracy and reliability of the memory and encoding related multifaceted electroencephalographic response (MERMER) technique for detecting information related to events subjects have experienced, despite subjects' efforts to conceal that knowledge. Information obtained through interviews was used to develop stimulus sets consisting of words and phrases presented to subjects visually by computer. Sets were composed of three types of stimuli: life experience-related (Probes), stimuli the subject was asked to memorize and respond to (Targets), and irrelevant information (Irrelevants). Each set of stimuli was tested on two individuals: (1) one individual who had participated in the event in question--and thus had the relevant information stored in his/her brain, and (2) one who had not. Six subjects were tested. Electrical brain responses to the stimuli were recorded non-invasively from the scalp and analyzed. MERMERs, (memory and encoding related multifaceted electroencephalographic responses), of which the P300 is a sub-component, were used to determine whether the subject had the relevant information stored in his brain (information present) or not (information absent), thus indicating whether or not each subject had participated in the real-life event in question. Bootstrapping was used to analyze and compare the responses to the three types of stimuli. As predicted, MERMERs were elicited by Probe stimuli only in the subjects who had participated in the investigated event, by Target stimuli in all subjects, and in no case by Irrelevant stimuli. For each of the six subjects, brain MERMER testing correctly determined whether the subject had participated in and consequently knew about the event in question (information present) or had not participated (information absent). The statistical confidence for this determination was 99.9% in five cases and 90.0% in one case. The article concludes with a discussion of areas of future research and the potential for using this new technology as an investigative tool in criminal cases.     

Accuracy of comparison decisions by forensic firearms examiners

This black box study assessed the performance of forensic firearms examiners in the United States. It involved three different types of firearms and 173 volunteers who performed a total of 8640 comparisons of both bullets and cartridge cases. The overall false-positive error rate was estimated as 0.656% and 0.933% for bullets and cartridge cases, respectively, while the rate of false negatives was estimated as 2.87% and 1.87% for bullets and cartridge cases, respectively. The majority of errors were made by a limited number of examiners. Because chi-square tests of independence strongly suggest that error probabilities are not the same for each examiner, these are maximum-likelihood estimates based on the beta-binomial probability model and do not depend on an assumption of equal examiner-specific error rates. Corresponding 95% confidence intervals are (0.305%, 1.42%) and (0.548%, 1.57%) for false positives for bullets and cartridge cases, respectively, and (1.89%, 4.26%) and (1.16%, 2.99%) for false negatives for bullets and cartridge cases, respectively. The results of this study are consistent with prior studies, despite its comprehensive design and challenging specimens.     

Establishing Identity: How Direct‐to‐Consumer Genetic Testing Challenges the Assumption of Donor Anonymity

The rise of direct‐to‐consumer genetic testing is challenging the rules and expectations of the fertility industry concerning donor anonymity. While ethicists debate whose rights should prevail, many donor conceived people, recipient parents and donors are currently sharing their genetic information, along with methods to identify genetic links, in vast online communities, invalidating donor anonymity and providing a platform for those who advocate globally for legislative change to support donor‐linking practices. This article looks at why it is important to access this information in relation to identity and kinship formation and how the Family Court Community can apply this knowledge in order to achieve better outcomes for children and families.
