Repeated Transaction in Rural Grain Markets of Ethiopia

This article uses the theory of repeated transaction to model exchange in rural grain markets. We examine the theoretical and empirical drivers of repeated transaction, as well as potential problems that may arise as a result of its widespread use. We develop a structural repeated game to represent buyer-seller relations in a developing country grain market, motivated by observations in Ethiopia. The model generates hypotheses regarding the logic that drives long-term tied transactions, as governed by information access, screening and investment costs, and time preferences. The model's predictions are tested using market transaction data collected in Ethiopia in 2009. Results support the view that a relational contract is driven by access to information and the costs of screening. Our major finding is that trust in relational trading can emerge through costly repeated interaction.     

The value of comparative analysis

Critical questions in both theory and practice can only be answered through comparative analysis whose value increases with the growing internationalization of public administration. Theoretically, it has long been assumed that public administration has to be a discipline reaching beyond one country and any specific culture, but the practical benefits derived from comparative analysis, such as more effetive policy making, better administrative arrangements and enhanced development prospects need also t o be stressed. Comparative bureaucratic corruption illustrates both the benefits and t h e difficult methodological problems encountered, in this case revealing why rich and stable polities can depend on legal–rational norms while poor and unstable polities a r e more susceptible t o systemic deviant conduct by public officials.     

Waging Peace on Okinawa

“Waging Peace on Okinawa” examines peace discourses as enacted in tours of battle sites and war (peace) memorials on the main island of Okinawa. Pointing out linkages with and divergences from mainland Japanese peace practices, the essay focuses on “peace guides” that have emerged as the backbone of educational tours that cater to Okinawan and, especially, mainland Japanese schoolchildren. Staffed by volunteers in conjunction with private and public organizations, peace guide tours and their supporting materials endeavor to promote peace by conveying a historical knowledge of the Battle of Okinawa that is more richly contextualized – “complete” – than that which is typically found in official textbooks, commercial tours, and patriotic pilgrimages. “Complete” in this context implies open discussion – even highlighting – of the violence and discrimination Okinawan civilians suffered at the hands of Japanese during the battle, but it also signals discriminatory treatment toward Okinawans before and beyond the battle (the most concrete example of the latter being the maintenance of U.S. military bases under the U.S.-Japan security arrangement). Peace guides and their supporters thus find themselves in a battle over historical representation that arguably has more to do with immediate political and economic issues than with setting the historical record straight.     

The Classification of Inkjet Inks Using AccuTOF™ DART™ (Direct Analysis in Real Time) Mass Spectrometry—A Preliminary Study

A novel approach for the analysis of inkjet inks is being reported. A time‐of‐flight mass spectrometer, coupled with a Direct Analysis in Real Time (DART?) ion source (AccuTOF? DART?), was used to determine if inkjet inks from various manufacturers and models of printers could be reliably differentiated, characterized, and identified. A total of 217 ink standards were analyzed. As inkjet printing often involves the use of multiple colors (e.g., cyan, magenta, yellow, and black) to form an image or text, two different approaches to creating a library of standards and sampling methods were evaluated for implementation in a standard operating procedure. This research will show that a microscopic examination of the region of interest is requisite to identify what colors were utilized during the printing process, prior to comparing with known standards. Finally, blind testing was administered with 10 unknown samples to assess the validity and accuracy of the methodology.     

Resource Material for Ethical Psychological Assessment of Symptom and Performance Validity,Including Malingering

The present paper offers resource material for evaluation of malingering, response bias, and symptom and performance validity. The material mostly consists of noncontroversial, paraphrased excerpts from relevant consensus statements, guidelines, codes, books, and articles. The five principles of the American Psychological Association (APA) ethics code were used to integrate the material. In addition, five other principles were needed (e.g., on science). The companion article on a new consensus statement on the ethical use of symptom and performance validity written for the Association for Psychological Advancement in Psychological Injury and Law (ASAPIL) in the journal Psychological Injury and Law (PIL; Bush, Ruff, & Heibronner, 2014) was instigated by and written partly based on the resources described in the present paper. The resources offered in the present paper are divided into the following sections: I. Malingering; II. Related Terms; III. APA Ethics Code; IV. Other Ethics Guidelines; V. Practice Guidelines; VI. Assessment Guidelines; VII. Other Ethical Sources; IX. Biases, Fallacies, Errors; X. Prior SVT-M/PVT-M Statements; XI. A New Ethical Model of Ten Principles; and XII. Instrumentation, and followed by Conclusions. The ten principles of the present ethical guidelines could be used to help revise the APA ethics code. The companion statement constitutes a major advance in the field and the present resource material facilitates its use.     

Analytical methods used for the discrimination of substances suspected to be bar soap: a preliminary study

The submission to forensic laboratories of unknown specimens suspected of being biological or chemical warfare agents has increased tremendously with the threat of terrorism. Oftentimes, a threatening correspondence that contains hoax materials is intended to make the recipient(s) believe they have been exposed to a toxin. In some cases, the perpetrator can use standard household products, such as detergents and soaps. Once these materials are received, they become forensic evidence and may be analyzed for identification and/or comparison with known seized material from a suspect(s). Two separate studies were conducted using different analytical protocols for bar soaps. In the first set, the forensic laboratory at the United States Secret Service conducted tests on 68 bars of soap using solid-phase microextraction and gas chromatography coupled with mass spectrometry. The 68 different soaps displayed unique total ion chromatogram profiles. Energy-dispersive X-ray analysis in conjunction with scanning electron microscopy was also used to characterize 46 of the 68 soaps as a preliminary study. In a second set of studies, as part of a homicide investigation, the laboratory at the California Department of Justice, Riverside, conducted examinations on 13 bars of soap by utilizing Fourier transform-infrared spectroscopy. The case study demonstrated that it is possible to distinguish some bar soaps using infrared analysis. Furthermore, the bar soaps could be distinguished from typical laundry detergents using this technique.
