Surface-sampling and analysis of TATP by swabbing and gas chromatography/mass spectrometry

The method of sample recovery for trace detection and identification of explosives plays a critical role in several criminal investigations. After bombing, there can be difficulties in sending big objects to a laboratory for analysis. Traces can also be searched for on large surfaces, on hands of suspects or on surfaces where the explosive was placed during preparatory phases (e.g. places where an IED was assembled, vehicles used for transportation, etc.).In this work, triacetone triperoxide (TATP) was synthesized from commercial precursors following reported methods. Several portions of about 6 mg of TATP were then spread on different surfaces (e.g. floors, tables, etc.) or used in handling tests. Three different swabbing systems were used: a commercial swab, pre-wetted with propan-2-ol (isopropanol) and water (7:3), dry paper swabs, and cotton swabs wetted with propan-2-ol. Paper and commercial swabs were also used to sample a metal plate, where a small charge of about 4 g of TATP was detonated. Swabs were sealed in small glass jars with screw caps and Parafilm^® M and sent to the laboratory for analysis. Swabs were extracted and analysed several weeks later by gas chromatography/mass spectrometry. All the three systems gave positive results, but wetted swabs collected higher amounts of TATP. The developed procedure showed its suitability for use in real cases, allowing TATP detection in several simulations, including a situation in which people wash their hands after handling the explosive.     

Multichannel Delivery of Public Services: A New and Complex Management Challenge

A strategic challenge facing all governments today is how to deliver services effectively and efficiently. At one time, they thought that they could meet this challenge by exploiting technology and going the E-government route with the promise of single-window, integrated, intelligent service delivery. Very quickly, however, they had to accept the fact that they would have to overcome a multitude of obstacles and that individual and corporate clients often preferred to receive service in traditional ways.

As a result, the delivery of public services is becoming increasingly multichannel: over the counter, by mail and telephone, over the Internet, via text and television, etc. There is therefore a need to identify some kind of model for managing this highly complex new phenomenon effectively and efficiently. By conducting research in the field with the help of case studies and international benchmarking, it was possible to identify the main variables in the degree of effectiveness and efficiency of multichannel public service delivery and develop the outline of a model representing the underlying factors.     

The Disappeared and the Mesa de Diálogo in Chile 1999–2001: Searching for Those Who Never Grew Old

This paper describes steps taken in order to deal with information regarding human rights abuses in Chile during the Pinochet regime, focusing on the most recent initiative, the Mesa de Diálogo (1999–2001) whose final report was given to president Lagos in January 2001. Two national initiatives, i.e. the establishment and reports of the Comisión de Verdad y Reconciliación (1991) and the following-up of this inquiry by the Corporación Nacional de Reparación y Reconciliación (1996) preceded La Mesa and are discussed in this paper. The paper concludes by suggesting that the Chilean transition to democracy will remain incomplete if the fate of the disappeared is not fully known and legally investigated.     

Using Stationarity Tests in Antitrust Market Definition

In this article it is argued that, if two products or geographicareas belong in the same market, their relative price must bestationary. Hence stationarity tests like the Augmented Dickey-Fullerand the KPSS can be helpful in delineating the relevant marketfor antitrust purposes, particularly for abuses of dominantpositions and agreements between competitors. The proposed procedureis strictly related to cointegration analysis but is simplerand has more general validity. An application to the Italianmilk market illustrates the technique.     

Myths about workplace violence, harassment and bullying

The objective of this article is to examine myths about various forms of violence which occurs in the workplace. Harassment, bullying or hounding at work, is a problem which has increased in magnitude and needs to be addressed. We therefore analyse the nature, perception, accusations and prevention of such myths with the objective of clarifying the tangible and intangible effects on the health of the victim, and the results such harassment provokes on the organisation of the workplace.

Soziale Mechanismen und mechanismische Erklärungen

Researchers in all fields dealing with reality wish to explain facts once they have described them. The prevailing account of explanation in the philosophical literature is the “covering law model”. According to this opinion, to explain a fact is to deduce the proposition(s) describing it from a theory together with the appropriate data, such as initial conditions. This is not how explanation is conceived of in the advanced factual sciences. In these, to explain a fact consists in unveiling the mechanism that makes the thing in question “tick”. In turn, a mechanism consists in the process(es) characteristic of the given thing. For example, metabolism is the central mechanism of living beings, learning is that of schools, and trade that of markets. I call mechanismic this kind of explanation. Therefore, anyone wishing to control a concrete system had better start by finding out its typical mechanisms, so as to maintain or alter them. This is what social control mechanisms, from cooperation and charity to legislation and violence, are supposed to accomplish. Typically, social mechanisms involve at least two levels, micro (individual) and macro (institutional). Consequently they can be neither understood nor designed on the basis of either individualism or holism. I argue that only systemism, the view that every thing is either a system or a component of one, can satisfactorily account for the centrality of mechanisms. Warning: Merton, Giddens and others often called “structure” what I call “mechanism”. Following mathematical usage, I define the structure of a system as the set of all the relations (in particular cohesive bonds) among the system component (endostructure), as well as the relations between the system components and things in the environment.     

Reform and regulation of electricity in colombia -uk experiences taken across the atlantic

The Colombian reform of its electricity industry was inspired in the British experience. The theoretical support and the actual application of the reform in the UK and Colombia are examined in this paper. Both theory and the British experience show the importance of designing an appropriate institutional framework for the sector that takes into account its specific features. The main challenges presented by the reform in Colombia are the control of the concentration of property, the introduction of antitrust and anticorruption mechanisms, as well as the development of new managerial skills that are required to confront the complex dynamics of the new environment.     

Mapping a way forward: Interest group selection and roles performed in engagement processes

Interest groups have much to offer citizen engagement activities, yet their contributions have been marginalized in recent years with the focus on more deliberative approaches for “ordinary citizens.” It seems that an either/or situation exists between citizen and interest group engagement. This article transcends this debate by delineating a methodology to inform the design of engagement processes that would include both citizens and groups in productive dialogue. Based on past interest group collaboration patterns, a collaborative method is outlined, which offers a way to identify and select interest groups for inclusion in engagement processes with citizens. The method is then applied to a case study of two water issues confronting the City of Hamilton in Ontario.     

Personal and Vicarious Experience with the Criminal Justice System as a Predictor of Punitive Sentencing Attitudes

This study examined the impact of prior personal or vicarious experience with the criminal justice system on sentencing attitudes. Existing research on sentencing attitudes has examined factors such as race, gender, income level, political affiliation, and education level, but few research studies have focused on actual contact with the criminal justice system and its influence on perceptions of sentencing as either too harsh or too lenient. The current study utilized data collected by the Roper Center for Public Opinion Research. Over 1,500 respondents were surveyed nationwide in 2006 regarding sentencing attitudes. Logistic regression analysis was utilized to assess the impact of factors of interest on sentencing attitudes. Results indicated that individuals who had been charged with a crime (personal experience), or who had an immediate relative or close friend who had been charged (vicarious experience), were more likely to perceive the criminal justice system as too harsh, regardless of race/ethnicity.
