An Amino Acid Model for Latent Fingerprints on Porous Surfaces*

Abstract: Analytical standards are needed in latent fingerprint detection for research and development as well as for quality control in routine work because normal fingerprints are too varied for comparison studies and tests. One way is to create latent fingerprints. For the amino acid sensitive detection method this can be achieved by coating test items with an amino acid solution using a modified commercial office bubble jet printer. Besides low costs, fast and easy preparation, the main advantage of a bubble jet printer is that the amino acid loading per area on the test item can be calculated by weighing the cartridge on a balance. This opens the possibility to determine the deviation for every printing series. The reproducibility of prints in a printing series made by one cartridge has a deviation of 2–16% and of prints made by different cartridges 20–25%.     

Turkish delight a public affairs study on family business: The influence of owners in the entrepreneurship orientation of family‐owned businesses

Family‐owned businesses (FOBs) are as unique as the families that own and control them. As reported by Miller, Steier, and Le Breton‐Miller (2003, p.513), the founders of many of these businesses try to continue their legacy and ensure continued family control via intergenerational succession, as when they hand over leadership to their children. The initial statistics suggest only approximately one third of FOBs survive into the second generation, with just 12% remaining “viable” by the third, and only about 3% operating into the fourth generation or beyond. Thus, one of the central problems for FOBs is this inability to ensure competent cross‐generational family leadership through successful transfer of ownership and management to the next family generation. This is a core issue for the modern public affairs practitioner and policy maker, nationally and internationally, and the Turkish case is a good example of the multicomplex issues evident in succession planning and leadership for business founders and leaders in these organisations. A firm's strategic orientation is an indicator of the processes developed to integrate new information, to coordinate decisions, to examine the evolution of environmental factors, and to assess new projects (Escriba‐Esteve, Sanchez‐Peinado & Sanchez‐Peinado, 2009). However, few studies have provided a framework that jointly analyses the FOB owner characteristics, the mediating processes and attitudes by which owners shape the direction of their family firms, and the effect of these postures on firm performance. This paper addresses the influence of family business owner, over the behaviour of FOBs. By treating FOB owners' characteristics as predictors of a firm's strategic orientation, we seek to provide a deeper understanding of how the characteristics of FOB owners shape decision making process and FOBs' behaviours in order to successfully survive in generations. This study introduced the concept of FOB's entrepreneurship orientation (EO) as a variable that mediates between FOB owners' characteristics and business performance. The objective of this paper is twofold: (a) to identify the demographic predictors FOBs' EO and (b) to analyse the role of EO as a mediator of the relationship between FOB owners' characteristics and FOBs' performance.     

Age-related differences when measuring political hypocrisy

This article aims to develop a scale for measuring political hypocrisy (conceptualized as the inconsistency between values publicly expressed by politicians and the behavior they actually demonstrate) and to explore the role of age in voters' perceptions of politicians' hypocrisy, analyzing if citizens belonging to different age groups may identify politicians' hypocrisy with a different detail. Results show that the 19-item scale of political hypocrisy—composed of three dimensions, called “ambiguity,” “slyness,” and “deceit”—has good psychometric properties, and that age-related differences when measuring political hypocrisy do exist (young voters show a greater awareness of the hypocritical behavior held by politicians). Furthermore, results suggest that the perception of political hypocrisy may vary according both to voters' political orientation and voting intention.     

Idealism,realism, and immigration: David Miller’s Strangers in Our Midst

David Miller’s Strangers in Our Midst is an important contribution to the debate among political philosophers about how liberal democratic states should deal with the issue of migration. But it is also a thoughtful statement concerning how best to do political philosophy and, as such, contributes also to the growing debate within Anglo-American political theory about the relative merits of ‘ideal’ versus ‘non-ideal’ normative theorising. Miller’s argument in the book builds on his earlier published work in suggesting that political philosophy should be ‘for Earthlings’: it should not be understood as a process of ideal theorising which ignores political reality. He argues that normative theorists should seek to resolve complex political problems by taking seriously the political context that makes these problems complex, rather than putting aside that context in the interests of deriving first principles. This is a controversial approach, which requires political philosophers to take more seriously than they often do the expressed concerns of citizens living in democratic states and the practical problems associated with applying normative principles in ways which actually help address the issue at hand. This piece discusses some of these themes, and the issue of migration more generally, in order to help frame the debate which follows.     

Corporate social responsibility in the European Union: a new trade barrier?

• This paper contributes to the discussion about Corporate social responsibility (CSR), competitiveness and trade policies, and how trade barriers emerge between countries already committed to CSR and those for whom CSR is still gaining ground. The authors describe the development of CSR within Europe and explain its role in shaping trade relationships. Gaining access to the European market, and obtaining the ‘licence to operate’ in light of strengthening commitment to CSR, is an issue for many companies. For countries outside the EU it is important to understand what CSR means in the European context and to recognize its implications for conducting business in the region. Further, through its economic power and resources, the EU sets standards and influences international trade norms. The authors conclude that the EU establishes CSR as a trade barrier for non‐complying companies in the terms of organizational culture, communication, capabilities and compliance.

Modernism's Legacy: Dialogue,Objectivity, and Justice in Mark Bevir's Democratic Governance

This article looks at Mark Bevir's ideas on the changing nature of the modern state, as expressed in his book, ‘Democratic Governance’. In the book, the author argues that recent developments in the theory and practice of politics have their intellectual roots in wider trends in the academic study of society and politics. In particular, he argues, the rise in what he and others have called ‘the new governance’ – that is, the shift in Britain and elsewhere away from centralised policy making and implementation by state institutions toward policy networks in which the state is merely one actor among many – has emerged as a direct consequence of the rise of ahistorical, universalist social science methodologies.     

A Novel Solvent-based Method to Separate Duct Tape from Porous Surface for Fingerprint Development

In this study, we have proposed a novel solvent-based method using a specific concentration of 3M™ Novec™ HFE-72DE and 7200 solvents to untangle duct tape from porous article with minimal impact to the quality of latent fingerprint deposited on the sticky-side surface of duct tape. A series of experiments determined that a mixture of 30% HFE-72DE:7200 (v/v) was found to be the most effective to separate various brands of duct tape from different types of porous surface, including office copy paper, newspaper, cardboard, and tissue wipe, which had been stored for up to 30 days before untangling. Further studies also revealed that 30% HFE-72DE:7200 was compatible with three common fingerprint development methods for porous articles, namely ninhydrin, indanedione-zinc, and physical developer. The nonflammability and low toxicity nature of this novel solvent mixture also make it ideal for separating duct tape from porous surface in laboratory or at crime scene.     

Enhancement of Latent Fingerprints on Fabric Using the Cyanoacrylate Fuming Method Followed by Infrared Spectral Mapping

A method has been developed for the visualization of latent fingerprints on fabrics, which is based upon cyanoacrylate (superglue) fuming followed by imaging using an infrared microscope. Results show that imaging on smooth, shiny fabrics such as polyester, silk, nylon, and acetate of different colors and patterns can give an improvement over existing enhancement methods. Results for cotton and polycotton were less successful and it is thought this may be due a combination of the presence of the carbonyl functional group in these fabrics as well as their absorbency to fingerprint sweat. The carbonyl peak (1700 cm^?1) provided the optimum spectroscopic feature to map and image a fingerprint. Comparisons between infrared mapping at a specific frequency range and principal component analysis showed that improved imaging was obtained with principal component analysis.     

Does Canadian Multiculturalism Survive through State Repression?

Emma Ambrose and Cas Mudde argued in this journal that the absence of far-right parties in Canada can be attributed, among other factors, to “strong state repression of dissent” on multiculturalism policy. This article provides numerous examples of such dissent, to show that the state repression invoked by Ambrose and Mudde does not exist. The article also argues that certain “supply-side” explanations for the absence of a strong far-right apply to the Canadian case. It notes, in particular, how Steven Harper's Conservative government occupied much of the political space that might otherwise have been available for far-right challengers.     

Comparison of Chemical and Heating Methods to Enhance Latent Fingerprint Deposits on Thermal Paper

A comparison is made of proprietary methods to develop latent fingerprint deposits on the inked side of thermal paper using either chemical treatment (Thermanin) or the application of heat to the paper (Hot Print System). Results with a trial of five donors show that the application of heat produces statistically significantly more fingerprint ridge detail than the chemical treatment for both fingerprint deposits aged up to 4 weeks and for a nine sequence depletion series. Subjecting the thermal paper to heat treatment with the Hot Print System did not inhibit subsequent ninhydrin chemical development of fingerprint deposits on the noninked side of the paper. A further benefit of the application of heat is the rapid development of fingerprint deposits (less than a minute) compared with up to 12 h for the Thermanin chemical treatment.
