The Effects of Environmental Exposure on the Optical,Physical, and Chemical Properties of Manufactured Fibers of Natural Origin

Manufactured fibers derived from natural origins include viscose rayon, azlon, and polylactic acid (PLA). A 2‐year study was conducted to document any changes these fibers undergo as a result of exposure to various environmental conditions. Fabric swatches representing each fiber type were exposed to freshwater, saltwater, heat, cold, ultraviolet light, or composter conditions. Fibers from the swatches were periodically analyzed using polarized light microscopy and Fourier transform infrared microspectroscopy. Fiber solubility and melting‐point behavior were measured every 6 months. Except for the complete degradation of viscose rayon in the composter, saltwater, and freshwater environs, no changes in the optical properties, infrared spectra, solubility, or melting points of the remaining fibers in any of the environments were observed. However, microscopic morphological changes were observed in fibers from two azlon swatches submerged in freshwater and saltwater, two PLA swatches exposed to ultraviolet light, and two viscose rayon swatches exposed to ultraviolet light.     

Hong kong public administration under stress: the significance and implications of management paradoxes

The purpose of this study is to identify the major obstacles to administrative reform in Hong Kong so as to generate a basis for addressing one critical question, “what is to be done to ensure the occurrence of effective reform?” Based on 35 interviews with 48 public executives, this researcher finds that there are various paradoxical forces acting in concert in their impacts upon the bureaucracy, that public executives are unable to cope with those forces, and that unless those paradoxes are effectively managed, administrators' ability to act (or to undertake reform measures) is seemingly very limited. Policy and research implications are discussed.     

Forensic Evidence and Criminal Investigations: The Impact of Ballistics Information on the Investigation of Violent Crime in Nine Cities,

We explore the impact of information from ballistics imaging hit reports on the investigation into violent crimes. Ballistics imaging hits link two crimes involving the same firearm by forensically matching tool marks on the fired bullets or cartridge cases. Interview data collected from detectives who received a hit report were used to explore the relationship between the presence of a hit report and outcomes in 65 gun‐related violent crime investigations in nine U.S. police agencies. Findings indicate hit reports rarely contribute to identification, arrest, charging, or sentencing of suspects, because of delays in producing hit reports. On average, hit reports were completed 181.4 days after the focal crime. This delay forces investigations to proceed without the benefit of information from ballistics analysis. Additionally, hit reports rarely contained detailed information that was immediately useful to investigators. Instead, hit reports required additional research by the investigator to unlock useful information.     

Evaluating interviews which search for the truth with suspects: but are investigators’ self-assessments of their own skills truthful ones?

Self-evaluation of one’s own performance has been found in prior research to be an enabler of professional development. The task of evaluation is also a core component of a model of the investigative interviewing of victims, witnesses and suspects, being increasingly used throughout the world. However, it remains the case that there has been little research as to how practitioners approach the task itself. The present study examined the topic through the lens of observing how effectively 30 real-life investigators in the UK undertook evaluation of their interviews, representing almost the entire investigative frontline workforce of a small law enforcement agency in this country. Using an established scale of measurement, both investigators’ and an expert’s ratings of the same sample of interviews were compared across a range of tasks and behaviours. It was found that in almost all the assessed behaviours, requiring of the investigators to provide a self-rating, their scores tended to significantly outstrip those applied to the sample by the expert. Reasons are explored for the investigators’ overstated assessments. Implications for practice are then discussed.     

Demography of the Legal Profession and Racial Disparities in Sentencing

The demography of the legal profession has changed rather dramatically in recent decades, yet the consequences of a more racially and ethnically diverse pool of lawyers for the administration of justice have not received significant attention. The present research examines how the racial composition of the local legal profession affects one facet of criminal law: the sentencing of convicted defendants. Building on prior work in the fields of law, stratification, and mobility, we hypothesize that racial and ethnic disparities in sentencing are mitigated where the legal profession is more diverse. In line with this hypothesis, analysis of data from a sample of large urban counties taken between 1990 and 2002 shows that the black-white racial disparity in sentencing attenuates as the number of black attorneys in the county increases, net of the percent black in the county and other possible confounding variables. Comparable results are found for Hispanics. The findings are discussed in the context of a demographically changing legal profession and prior work on racial disparities in the justice system.     

Profiling the mobile customer – Privacy concerns when behavioural advertisers target mobile phones – Part I

Mobile customers are being tracked and profiled by behavioural advertisers to be able to send them personalized advertising. This process involves data mining consumer databases containing personally-identifying or anonymous data and it raises a host of important privacy concerns. This article, the first in a two part series on consumer information privacy issues on Profiling the Mobile Customer, addresses the questions: “What is profiling in the context of behavioural advertising?” and “How will consumer profiling impact the privacy of mobile customers?” The article examines the EU and U.S. regulatory frameworks for protecting privacy and personal data in regards to profiling by behavioural advertisers that targets mobile customers. It identifies potential harms to privacy and personal data related to profiling for behavioural advertising. It evaluates the extent to which the existing regulatory frameworks in the EU and the U.S. provide an adequate level of privacy protection and identifies key privacy gaps that the behavioural advertising industry and regulators will need to address to adequately protect mobile consumers from profiling by marketers. The upcoming second article in this series will discuss whether industry self-regulation or privacy-enhancing technologies will be adequate to address these privacy gaps and makes suggestions for principles to guide this process.¹
