Effect of Aging and Surface Interactions on the Diffusion of Endogenous Compounds in Latent Fingerprints Studied by Mass Spectrometry Imaging,

The ability to determine the age of fingerprints would be immeasurably beneficial in criminal investigations. We explore the possibility of determining the age of fingerprints by analyzing various compounds as they diffuse from the ridges to the valleys of fingerprints using matrix‐assisted laser desorption/ionization mass spectrometry imaging. The diffusion of two classes of endogenous fingerprint compounds, fatty acids and triacylglycerols (TGs), was studied in fresh and aged fingerprints on four surfaces. We expected higher molecular weight TGs would diffuse slower than fatty acids and allow us to determine the age of older fingerprints. However, we found interactions between endogenous compounds and the surface have a much stronger impact on diffusion than molecular weight. For example, diffusion of TGs is faster on hydrophilic plain glass or partially hydrophilic stainless steel surfaces, than on a hydrophobic Rain‐x treated surface. This result further complicates utilizing a diffusion model to age fingerprints.     

Job satisfaction among frontline police officers in China: the role of demographic,work-related,organizational and social factors

This study was intended to add to information about the underinvestigated policing studies in China. The possible impact of demographic characteristics, work-related variables, and organizational management and social variables on police job satisfaction was investigated. Data were collected through a self-report survey administered to a sample of sworn police officers training in a national police university in China (N?=?393). Results indicated that work-related characteristics associated with variety and stress, and organizational variables associated with professional development and peer cohesion were the most important predictors of job satisfaction in this sample of police officers.     

Postal Service Reforms in Solomon Islands of the South Pacific: Evaluating Consequences for Public Service Delivery and Customer Satisfaction

The changing environment of the postal sector over the last decade has increased the urgency for governments worldwide to re-examine regulations governing how their public postal administrations operate. The need to increase service efficiency and quality is a critical strategic focus, given the increasing technological competition, rising operational costs, and changing customers' needs and expectations. There are many success stories, particularly from developed countries, highlighting improved service quality following corporatization of their public postal administration. This particular study revealed that reforms of the Solomon Islands postal service have had some positive influence on the level of customer satisfaction.     

Citizen Satisfaction: A Multicriteria Satisfaction Analysis

Governments across Europe face the challenge of responding to public demand for more valuable, responsive, and efficient and effective services. In this article we will evaluate the public services in Greece. More specifically, this article refers to a citizen's satisfaction web survey for Citizens’ Service Centers. The analysis of the data is based on the MUSA (Multicriteria Satisfaction Analysis) method. MUSA is an ordinal regression model which is based on the principles of multicriteria decision analysis. The method is an instrument to evaluate quantitative global and partial satisfaction levels and to determine the weak and strong points of citizens Service Centers. Furthermore the results of this study will help the Citizens Service Centers to develop more effective services.     

Does User Co-Production of Public Service Delivery Increase Satisfaction and Trust? Evidence From a Vignette Experiment

Whereas it is assumed that involving users in the delivery of public services yields more positive evaluations of those services, this study shows that levels of satisfaction and trust are not necessarily positively affected by such user co-production. An experimental vignette design among students (n = 174) is used to analyze the differences concerning trust and satisfaction between co-produced and non-co-produced public services. In some cases, the results suggest, co-production actually leads to less satisfaction and trust. This might be explained by the self-serving bias, which states that co-producers take credit for success but blame service providers for failure.

Leave it at the gate: job stress and satisfaction in correctional staff

Though academic literature firmly establishes an inverse relationship between job stress and job satisfaction, global correctional studies fail to examine the extent of that affiliation on overall correctional job satisfaction. As such, this study uses a faceted approach to explore underlying relationships between organizational, job, and personal characteristics of correctional staff and causes of job stress and satisfaction. Using the Job Satisfaction Survey, nine aspects of job satisfaction are considered. The Work Stress Scale for Correctional Officers’ analyses of five areas of stress directly related to correctional environments. This study examines both uniform and nonuniform staff assigned to a minimum security prison. On average, staff scored well below the average American worker on the Job Satisfaction Survey. Job satisfaction was predicted exclusively by job characteristics or stressors, including the job itself, role conflict, and ambiguity, and the physical condition of the prison, while employee demographic variables and variables that measure healthy lifestyles (such as sleep and exercise) were not significant predictors. While job stress does predict a substantively significant portion of job satisfaction (21%), there is still room to improve prediction.

Mass Media Paradoxes in the Bulgarian Elections of 2001

ABSTRACT

Electoral year '01 marked another headway of the country along the road of its democratic development.

For the first time after 1989, the parliamentary elections (fifth in a row) were not held before their time, but after a normally completed cycle. The unproductive bipolar model of alternating the main political opponents was broken. A new and unusual player of royal blood emerged, who, without any firm structures, with little funds, and under the conditions of political and media hostility, won firmly the majority vote.

For the first time since the outset of transition, a representative of the Left qualified for the presidential post, which was the most articulate acknowledgement that the Left has changed and the most eloquent criticism of the former bearers of public confidence.

Both parliamentary and presidential elections '01 took part under the conditions of a free media system and after the advent of Internet into political campaigning, information, and analysis. Both campaigns and election returns, however, manifested grave professional problems in the domain of sociology and the media that failed to meet the principal requirement for unbiased information and predictability of developments and results. In this situation, the society manifested considerable civil advancement. The paradox of that electoral year was that both Par-Lilia Raycheva is affiliated with the Faculty of Journalism and Mass Communication, The St. Kliment Ohridsky Sofia University, Bulgaria. Parliament and President were elected contrary to sociological forecasts and attitudes.
