Application of Micro‐Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy to Ink Examination in Signatures Written with Ballpoint Pen on Questioned Documents

Questioned documents examined in a forensic laboratory sometimes contain signatures written with ballpoint pen inks; these signatures were examined to assess the feasibility of micro‐attenuated total reflectance (ATR) Fourier transform infrared (FTIR) spectroscopy as a forensic tool. Micro‐ATR FTIR spectra for signatures written with 63 ballpoint pens available commercially in Korea were obtained and used to construct an FTIR spectral database. A library‐searching program was utilized to identify the manufacturer, blend, and model of each black ballpoint pen ink based upon their FTIR peak intensities, positions, and patterns in the spectral database. This FTIR technique was also successfully used in determining the sequence of homogeneous line intersections from the crossing lines of two ballpoint pen signatures. We have demonstrated with a set of sample documents that micro‐ATR FTIR is a viable nondestructive analytical method that can be used to identify the origin of the ballpoint pen ink used to mark signatures.     

TOF‐SIMS Analysis of Red Color Inks of Writing and Printing Tools on Questioned Documents

Time‐of‐flight secondary ion mass spectrometry (TOF‐SIMS) is a well‐established surface technique that provides both elemental and molecular information from several monolayers of a sample surface while also allowing depth profiling or image mapping to be performed. Static TOF‐SIMS with improved performances has expanded the application of TOF‐SIMS to the study of a variety of organic, polymeric, biological, archaeological, and forensic materials. In forensic investigation, the use of a minimal sample for the analysis is preferable. Although the TOF‐SIMS technique is destructive, the probing beams have microsized diameters so that only small portion of the questioned sample is necessary for the analysis, leaving the rest available for other analyses. In this study, TOF‐SIMS and attenuated total reflectance Fourier transform infrared (ATR‐FTIR) were applied to the analysis of several different pen inks, red sealing inks, and printed patterns on paper. The overlapping areas of ballpoint pen writing, red seal stamping, and laser printing in a document were investigated to identify the sequence of recording. The sequence relations for various cases were determined from the TOF‐SIMS mapping image and the depth profile. TOF‐SIMS images were also used to investigate numbers or characters altered with two different red pens. TOF‐SIMS was successfully used to determine the sequence of intersecting lines and the forged numbers on the paper.

Child protective intervention in the context of welfare reform: The effects of work and welfare on maltreatment reports

Recent changes in welfare policy have produced changes in parental work and welfare receipt. These factors are assessed in relation to investigated reports of child abuse and neglect using survey data on 1998 welfare recipients in nine Illinois counties, in conjunction with longitudinal administrative data on cash welfare benefits, employment, and child abuse and neglect reports. Trend analyses show that rates of child maltreatment reports among welfare recipients have risen since the passage of PRWORA in 1996. Findings from multivariate analyses indicate that parental employment has a protective effect on reports to child protection systems (CPS), that this effect is greatest when combined with welfare receipt, and that this effect becomes stronger over time. Those who receive welfare in the absence of employment face a significantly greater risk of CPS involvement, even compared with those who neither work nor receive welfare. © 2003 by the Association for Public Policy Analysis and Management

How Filipina Maids Are Treated in Hong Kong—A Comparison Between Chinese and Western Employers

This study compares Chinese and Western employers in Hong Kong in terms of their treatment of Filipina domestic helpers in four major areas: atmosphere of work environment, consideration, social psychological distance, and personal space. The data were based on in-depth and structured interviews, mainly with Filipina helpers who have served both types of employers. A few Chinese and Western employers were also interviewed. The findings indicate that the Filipina maids, in general, are more satisfied with their Western employers, who tend to provide them with an easier and more comfortable work environment; are more considerate; are more likely to treat them on equal terms; and to allow them more personal space. Within group variations in the treatment of maids are greater among Chinese employers than Western employers. This means that, in terms of the treatment of Filipina maids, Western employers in Hong Kong are more homogeneous and tend to concentrate on the positive side, whereas Chinese employers are more diversified.     

The Influence of Emotional Intelligence on Negotiation Outcomes and the Mediating Effect of Rapport: A Structural Equation Modeling Approach

Although early research on negotiation focused on cognition and decision‐making processes, recently, negotiation scholars have started to pay attention to the importance of emotion in negotiation and have suggested that emotional intelligence is likely to improve negotiation performance. Few studies, however, have tested the relationship between emotional intelligence and negotiation outcomes. This study contributes by empirically testing the influence of emotional intelligence on specific negotiation outcomes (joint gain, trust between parties, and the desire of parties to work together again) and also examines the mediating effects of rapport. We used a laboratory experimental design with 202 participants to test the hypotheses. We found that a negotiator's emotional intelligence was correlated with his or her counterpart's trust level and desire to work again but had no effect on joint gain. In addition, rapport fully mediated the relationship between emotional intelligence and desire to work again, and between emotional intelligence and trust.     

Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy Analysis of Red Seal Inks on Questioned Document

Seals are traditionally used in the Far East Asia to stamp an impression on a document in place of a signature. In this study, an accuser claimed that a personal contract regarding mining development rights acquired by a defendant was devolved to the accuser because the defendant stamped the devolvement contract in the presence of the accuser and a witness. The accuser further stated that the seal ink stamped on the devolvement contract was the same as that stamped on the development rights application document. To verify this, the seals used in two documents were analyzed using micro‐attenuated total reflectance Fourier transform infrared spectroscopy and infrared spectra. The findings revealed that the seals originated from different manufacturers. Thus, the accuser's claim on the existence of a devolvement contract was proved to be false.     

Modern Scientific Evidence Pertaining to Criminal Investigations in the Chosun Dynasty Era (1392–1897 A.C.E.) in Korea

A guidebook detailing the process of forensic investigation was written in 1440 A.C.E. It outlines the fundamentals and details of each element of criminal investigation during the era of the Chosun dynasty in Korea. Because this old guidebook was written in terms of personal experience rather than on scientific basis, it includes many fallacies from the perspective of modern forensic science. However, the book describes methods to form a scientific basis for the experiments performed. We demonstrate the modern scientific basis for ancient methods to monitor trace amounts of blood and detect lethal arsenic poisoning from a postmortem examination as described in this old forensic guidebook. Traces of blood and arsenic poisoning were detected according to the respective color changes of brownish red, due to the reaction of ferric ions in blood with acetic ions of vinegar, and dark blue, due to the reaction of silver with arsenic sulfide.
