Moistened hands do not necessarily allude to high quality fingerprints: the relationship between palmar moisture and fingerprint donorship

We explored the quality distribution of ninhydrin-developed prints on A4 bond paper in two groups of individuals, in Israel and in India. While the quality distributions of the developed marks in both countries had some dissimilarities, both groups showed the expected bell-shape distribution, with the majority of the donors belonging to the central zone, defined as "average" or "good." Attempt was made to correlate between a physiological feature, palmar moisture, and the fingerprint donorship. As a rule, high fingermark quality could be associated with sweating hands, but there were individuals with moist palms whose fingermarks had a low score and vice versa. This finding supports the logical but hitherto unproven assumption that besides the amount of palmar sweat, the other physiological factor governing the prints' quality is the total amount of substrate, amino acids in this case, in the latent deposits, which depends on the substrate concentration in the sweat.     

Effect that the relative abundance of copper oxide and zinc oxide corrosion has on the visualization of fingerprints formed from fingerprint sweat corrosion of brass

From an examination of the fingerprint sweat corrosion of 40 different individuals on α phase brass, we show that an increase in visualization can be achieved by applying a negative potential to the brass followed by the introduction of a conducting powder. Previously, this technique has been demonstrated only for a positive applied potential and a corrosion product that was dominated by p-type copper (I) oxide. X-ray photoelectron and Auger electron spectroscopic analyses of the surface of the corroded brass show that an increase in visualization with a negative applied potential corresponds with an increase in the concentration of n-type zinc oxide relative to p-type copper (I) oxide with the Cu:Zn ratio <0.8:1. Work function conditions for the formation of an n-type zinc oxide/brass rectifying Schottky barrier are fulfilled.     

Bite marks: physical properties of ring adhesion to skin-phase 1

Abstract: Unsupported excised skin may shrink by as much as 50% or more. In 1981, a method was developed for ring adhesion to skin with the goal of minimizing tissue distortion upon excision. Five modified versions of the technique bearing the author’s name followed (Dorion types I, II, III, IV, and V). The scientific literature reveals little supporting empirical evidence for the preferential use of one adhesive/suturing technique over another. This study compares the use of various bonding materials (Loctite Super Glue gel^®, Dermabond?, Vetbond?), cleaning agents (ethanol, dishwashing liquid, and shaving cream), and depilatory (Veet^®) on the effects of ring adhesion to skin. The conclusions indicate that surface wetness is the most influential factor affecting ring adhesion to skin, followed by the type of bonding material, its “freshness,” and by the cleaning agent used to prepare the skin. The use of a depilatory or shaving cream is to be avoided.     

Visualizing latent fingerprints on color-printed papers using ultraviolet fluorescence

Laser detection of latent fingerprints on a white paper has been performed, previously. Ultraviolet fluorescence from various kinds of printer toner and ink used for home printers were measured to study fluorescence imaging of fingerprints on a color-printed white paper. The experimental system consisted of a nanosecond pulsed tunable laser and a cooled CCD camera. Excitation wavelengths are 230 and 280 nm. Fourteen printers consisting of three color laser printers, three color inkjet printers, five monochrome laser printers, two monochrome copy machines, and a color copy machine were tested. Toner and ink of most printers exhibited fluorescence in the region from 360 to 550 nm. In most cases, clear fluorescence images were obtained by time-resolved imaging with a band-pass filter and 280-nm excitation. However for toners from laser color printers that showed strong fluorescence, better results were obtained with 230-nm excitation. Latent fingerprints on a photograph page and a black-character page of a newspaper were also imaged.

A BETTER BEGINNING: FAMILY LAW IN THE FIRST YEAR OF LAW SCHOOL

The American Bar Association's Section of Legal Education and Admission to the Bar's Standards Review Committee has focused law schools' efforts to modify their curriculum with an appeal to focus on outcomes and assessments. A cornerstone of the outcomes and assessments discussion is skills training. The committee's call for more skills training has prompted family law faculty to consider innovative methods to bring that training into substantive courses or to bring the substantive curriculum into a skills course. This essay discusses how law faculty are incorporating family law doctrines into first‐year legal research and writing courses.

全球化背景下中国公共行政本土研究:动力、内涵与进路

中国公共行政学者对于公共行政身份危机的反思为公共行政本土研究提供了契机。在本土研究过程中,对推动本土研究的动力、本土化内涵及其进路的分析是进一步开展本土研究的前提。文章试图在全球化背景下审视中国公共行政的本土研究。从中国改革开放的历史背景入手探讨和分析推动中国公共行政本土研究的动力;从全球化与本土化关系角度分析了公共行政本土化的内涵;最后从学者的学术自觉、本体论、知识论和方法论角度分析了进行本土化研究的进路。     

妇女贫困：从农村到城乡，从收入贫困到多维贫困——2000年以来中国“妇女贫困”研究评述与展望
