An interpretation of Argentine economic growth since 1930. Part II∗

This article focuses on the measurement of embodied technological change. It develops the core-machinery approach to capital measurement, which is based on an engineering perspective on technological change. Using technical characteristics of different types of machinery, technical progress in the capital stock can be decomposed into incremental innovation in existing machinery and radical shifts to new technologies. The usefulness of this approach is illustrated by an analysis of embodied technological change in the Indonesian spinning and weaving industries. The core-machinery measure is compared with more traditional measures of the capital stock which are based on price information. Strengths, weaknesses and relevance of the new measure are discussed.     

The measurement of institutional characteristics of nations: Methodological considerations

A major barrier to the quantitative investigation of interactions between economic and non‐economic influences in economic development is the lack of adequate indicators of institutional traits of nations. Our purpose in this paper is to consider the methodological procedures involved in the development of qualitative sociopolitical and economic indicators.

The first sections of the paper deal with various aspects related to the subject of measurement. This is necessary because misconceptions regarding the nature of ‘qualitative measurement’ are common, and misleading contrasts between qualitative and quantitative measurement are frequently made. The last four sections illustrate the procedures for the measurement of institutional indicators by applying them to the quantification of the concept of political participation in developing countries.     

Nepali fuelwood production and consumption: Regional and household distinctions,substitution and successful intervention

This article uses household data from Nepal's two major populated regions (and 27 of 59 districts within those regions) to examine fuelwood consumption and production. In contrast with a purely market assessment, household analysis includes production which is consumed in the producing household. The household regressions yield coefficients and elasticities that are very different from and more reliable than a comparable assessment of market demand and supply. Household results generally support the hypotheses that expenditures on fuelwood are a small share of total household activity and that fuelwood is not sufficiently scarce to alter household behaviour. Fuelwood is sufficiently scarce, however, to alter behaviour for those households in the hill region that do not participate in market exchange. These households may be the best targets for public market interventions designed to alter fuelwood supply and deforestation.     

A New Method for the Removal and Analysis of Small Particles Adhering to Carpet Fiber Surfaces,,

Fibers are a commonly encountered evidence type and fiber comparisons are routinely conducted. When the characteristics of questioned and known fibers correspond, the probative value is limited because the characteristics compared are determined by their manufacture. It would be valuable to test the hypothesis that questioned fibers originated from a specific carpet. One means of testing this is to analyze fine particles on the fibers. A procedure was developed for removing adhering particles from fibers and preparing them for scanning electron microscopy/ energy dispersive X‐ray spectrometry (SEM/EDS) analysis. The efficacy of several fluids (acetone, ethanol, hexanes, aqueous ethanol, aqueous sodium hexametaphosphate) and agitation methods (sonication and vortexing) for removing particles from fibers was evaluated. The most effective method evaluated was sonication in ethanol for 10 min. The recovered particles were filtered onto a polycarbonate filter and analyzed by automated SEM/EDS analysis to generate data on the particle assemblage. This method makes possible future research to test the within‐item and between‐item variability of particle assemblages on fibers.     

Raman Spectroscopy as a Simple,Rapid, Nondestructive Screening Test for Methamphetamine in Clandestine Laboratory Liquids

Raman spectroscopy has found increased use in the forensic controlled substances laboratory in recent years due to its rapid and nondestructive analysis capabilities. Here, Raman spectroscopy as a screening test for methamphetamine in clandestine laboratory liquid samples is discussed as a way to improve the efficiency of a laboratory by identifying the most probative samples for further workup among multiple samples submitted for analysis. Solutions of methamphetamine in ethanol, diethyl ether, and Coleman fuel were prepared in concentrations ranging from 0.5% to 10% w/v, and Raman spectra of each were collected. A concentration‐dependant Raman peak was observed at 1003 per cm in each solution in 4% w/v and greater solutions. Case samples were analyzed and also found to reliably contain this diagnostic peak when methamphetamine was present. The use of this diagnostic indicator can save the forensic controlled substances laboratory time and materials when analyzing clandestine laboratory liquid submissions.     

Ultrafast Amplification of DNA on Plastic Microdevices for Forensic Short Tandem Repeat Analysis

The majority of microfluidic devices used as a platform for low‐cost, rapid DNA analysis are glass devices; however, microchip fabrication in glass is costly and laborious, enhancing the interest in polymeric substrates, such as poly (methyl methacrylate) (PMMA), as an inexpensive alternative. Here, we report amplification in PMMA polymerase chain reaction (PCR) microchips providing full short tandem repeat profiles (16 of 16 loci) in 30–40 min, with peak height ratios and stutter percentages that meet literature threshold requirements. In addition, partial profiles (15 of 16 loci) were generated using an ultrafast PCR method in 17.1 min, representing a ~10‐fold reduction in reaction time as compared to current amplification methods. Finally, a multichamber device was demonstrated to simultaneously amplify one positive, one negative, and five individual samples in 39 min. Although there were instances of loci dropout, this device represents a first step toward a microfluidic system capable of amplifying more than one sample simultaneously.     

How American Commercial Bail Developed Differently from Other Common Law Countries

Outside the United States those countries sharing the common law tradition are pervasively hostile to commercialization of the bail process, whereas in the United States it is the typical approach. In some jurisdictions payment for bail is a crime; in others it is simply obstructed by various civil legal disabilities. How the American branch of the common law heritage came to deviate so strikingly from the rest on the matter of commercial bail is the topic of this article.

Beginning in the second half of the nineteenth century, courts principally in Ireland, England, and India began to act against payment to bail sureties on the concept that any indemnification of them—even partial—undermined their reliability. Irish courts took the approach that indemnified potential sureties were unreliable and should be rejected by courts. Where all potential sureties were indemnified, bail should be denied. In England courts declared agreements to indemnify sureties illegal contracts contrary to public policy, which would not be enforced by courts. While India took up the refinement of this position, England went on to declare agreements to pay bail sureties to be criminal conspiracies.

Meanwhile in the United States a circumscribed version of the position that indemnification contracts were against public policy—and therefore illegal and unenforcible—actually gained acceptance between 1870 and 1912. In 1912, however, Justice Holmes in Leary v. U.S. renounced the common law concept of bail sureties in favor of an “impersonal and wholly pecuniary” view. This terminated the anti-indemnification movement. Courts soon noted the detrimental effects of commercialism on bail.     

Hostage negotiation in Costa Rica

This article compares legal and procedural constraints that operate on United States and Costa Rican hostage negotiations. In an effort to better understand the Costa Rican police system, comparisons are drawn between United States law enforcement agencies, United States military services and the Costa Rican police system. The introductory material lays the foundation for a discussion of hostage negotiation as it is practiced in Costa Rica prior to and after hostage negotiation training.     

Generational Transmission of Collective Memory about Tiananmen in Hong Kong: how young rally participants learn about and understand 4 June

This article addresses the problem of generational transmission of collective memory in Hong Kong about the 1989 Tiananmen Square incident. It focuses on the young participants in the annual 4 June commemoration rallies and examines the process of mnemonic socialization that brought them into the community of 4 June commemoration. Drawing upon a rally onsite survey and in-depth interviews, this study found that many young people went through a dynamic process of gradual discovery in which various social institutions—school, family and media—played complementary roles. Their understanding of Tiananmen tended to be simplified and essentialized. Yet the loss of details through essentialization has arguably allowed them to uphold a clear-cut moral judgment regarding the event and dismiss certain memory-blurring discourses straightforwardly.
