Enhancing contrast of fingerprints on plastic tape

Many of the currently available fingerprinting methods have limited ability to visualize fingerprints on plastic tape without expensive equipment or significant handling of the sample. This is especially true for visualizing fingerprints on black electrical tape. This study sought a hands-off method to produce easy visualization of fingerprints on different types of plastic tape, including black electrical tape, without the need for expensive equipment. The methods selected were to sublime disperse dyes into the tape, both with and without the fuming of cyanoacrylate, everywhere except for where the fingerprint was applied. The resulting color contrasts provided enough differentiation to visualize fingerprints on plastic tape under ambient light. Sequential fuming with cyanoacrylate followed by disperse dyes provided the best visualizations on all tapes, and cyanoacrylate followed by disperse yellow 211 clearly visualized fingerprints on black electrical tape.     

Do Policy Horizons Structure the Formation of Parliamentary Governments?: The Evidence from an Expert Survey

This article tests the hypothesis that parties in West European parliamentary systems operate under the constraint of "policy horizons," that is, limits or bounds on the extent to which they can compromise on policy for the purpose of entering coalition governments. The test is based on a new expert survey covering thirteen West European parliamentary democracies in which respondents were asked not only to locate party positions on a number of policy dimensions, but also to estimate the parties' limits of acceptable compromise on each dimension. The survey data are first analyzed using a new computer program, Horizons 3D, to determine which parties have intersecting horizons in these systems—and hence the ability to form coalition governments under the hypothesis. These calculations are then employed to assess whether policy horizons structure the choice of governing coalition beyond any effect conveyed by the policy distances among parties. Although the potential for error in these data is considerable, the estimated horizons, with few exceptions, appear to play the role hypothesized for them .     

Institutional trustworthiness and national security governance: Evidence from six European countries

This article examines the relationship between the institutional trustworthiness of security agencies in the context of data‐intensive security practices. It focuses on the public's acceptance of the way digital surveillance technologies feed into large‐scale security data analytics. Using the case of deep packet inspection (DPI), survey data gathered in six European countries (n = 1,202) demonstrates that security agencies' institutional trustworthiness directly and indirectly influences public acceptance of DPI. Against a backdrop of declining public trust in government and a climate of intense international terrorist threat, governments around the world are appealing to citizens to trade privacy for enhanced security. This article supports calls for security agencies and their respective governments to engage with the democratic process to enrich security and privacy at all levels of public security governance and for the common good.     

Neo-feudalism in Latin America? Globalisation,agribusiness, and land re-concentration in Chile

This article traces the effects of globalisation on an export-oriented ‘hotspot’ in Chile's non-traditional agricultural export sector. Drawing on evidence from fieldwork carried out in 1994 and in 2004/5, the analysis examines the impact of neoliberal policy over the past two decades. Although the fruit export sector is seen as a key success story of the Chilean economy, and is an area to which small producers are often encouraged to ‘reconvert’, it is argued here that the outcome has been land re-concentration, marginalisation and proletarianisation. Small farmers become increasingly locked into dependent relationships with larger landowners and agribusiness, whilst others form a rural proletariat that serves these concerns. Whilst some commentators have labelled this process ‘semi’ or ‘neo’ feudalism, this article maintains that we are witnessing a deepening fragmentation of the peasantry driven by the continued development of capitalism. The gains of the earlier land reform period are being eroded as rural Chile differentiates and depeasantisation unfolds.     

Behind the ‘Miracle’: Non‐Traditional Agro‐Exports and Water Stress in Marginalised Areas of Ica,Peru

Expansion in the non‐traditional agricultural export sector following neoliberal reform has precipitated an economic transformation in Peru. Non‐traditional agricultural export growth has brought environmental, social and distributive costs. This article critically examines the Peruvian asparagus boom and the impact of this on water availability among marginal groups. Based on primary case study fieldwork, the paper asserts that the agro‐export model is causing the over‐exploitation of important groundwater supplies in the Ica Valley where almost all of Peru's fresh asparagus is produced. This reveals wider issues concerning neoliberal development and the political economy of natural resource allocation in Latin America.
