Automated processing of forensic casework samples using robotic workstations equipped with nondisposable tips: contamination prevention

An automated process has been developed for the analysis of forensic casework samples using TECAN Genesis RSP 150/8 or Freedom EVO liquid handling workstations equipped exclusively with nondisposable tips. Robot tip cleaning routines have been incorporated strategically within the DNA extraction process as well as at the end of each session. Alternative options were examined for cleaning the tips and different strategies were employed to verify cross-contamination. A 2% sodium hypochlorite wash (1/5th dilution of the 10.8% commercial bleach stock) proved to be the best overall approach for preventing cross-contamination of samples processed using our automated protocol. The bleach wash steps do not adversely impact the short tandem repeat (STR) profiles developed from DNA extracted robotically and allow for major cost savings through the implementation of fixed tips. We have demonstrated that robotic workstations equipped with fixed pipette tips can be used with confidence with properly designed tip washing routines to process casework samples using an adapted magnetic bead extraction protocol.     

Fourier transform infrared reflectance spectra of latent fingerprints: a biometric gauge for the age of an individual

To determine if changes in fingerprint infrared spectra linear with age can be found, partial least squares (PLS1) regression of 155 fingerprint infrared spectra against the person's age was constructed. The regression produced a linear model of age as a function of spectrum with a root mean square error of calibration of less than 4 years, showing an inflection at about 25 years of age. The spectral ranges emphasized by the regression do not correspond to the highest concentration constituents of the fingerprints. Separate linear regression models for old and young people can be constructed with even more statistical rigor. The success of the regression demonstrates that a combination of constituents can be found that changes linearly with age, with a significant shift around puberty.     

Rediscovering Implementation: Public Sector Contracting and Human Services

There is vast literature on how to implement public policies, with endless case studies emphasising a few key lessons. The drive to contracting in the public sector raises familiar threats to coherent program implementation, and adds those of control and incentives. Contracting fragments program responsibility among multiple contractors, and separates policy agencies from service delivery contractors. It raises questions about political control and accountability, and the prospect of gaps between intention and outcome. This paper 'rediscovers implementation' by reviewing the practical difficulties of constructing public-private relationships which can deliver quality human services. After considering broad arguments about the efficacy of contracting, the paper turns to the provision of human services by examining the contracting out of welfare services and the Job Network. Our argument is modest: that public sector contracting fails if the challenges of implementation are not addressed explicitly, since service delivery through the private sector can falter for exactly the same reasons as traditional public bureaucracies.     

A Framework for Unifying Formal and Empirical Analysis

An important disconnect exists between the current use of formal modeling and applied statistical analysis. In general, a lack of linkage between the two can produce statistically significant parameters of ambiguous origin that, in turn, fail to assist in falsifying theories and hypotheses. To address this scientific challenge, a framework for unification is proposed. Methodological unification leverages the mutually reinforcing properties of formal and applied statistical analysis to produce greater transparency in relating theory to test. This framework for methodological unification, or what has been referred to as the empirical implications of theoretical models (EITM), includes (1) connecting behavioral (formal) and applied statistical concepts, (2) developing behavioral (formal) and applied statistical analogues of these concepts, and (3) linking and evaluating the behavioral (formal) and applied statistical analogues. The elements of this EITM framework are illustrated with examples from voting behavior, macroeconomic policy and outcomes, and political turnout.

‘Whatever It Takes'Despite European leaders’ efforts to address fears over the euro, there is no quick solution to the crisis

While most of Europe goes on holiday or sits glued to the London Oympics,the euro sovereign debt crisis continues to preoccupy policymakers.In the last week of July,it appeared as if the crisis had reached Olympian proportions as the Spanish Government looked set to follow its banks and seek a bailout from the EU.Dealing with Greece is one problem.Dealing with Spain,and potentially Italy,are problems of a vastly different dimension.As rumors grew of a Spanish bailout request,markets fell and the euro dipped against the dollar.     

Information diffusion within the electorate:: the asymmetric transmission of political–economic information

This paper examines the connection between information and expectations. Drawing upon Lazarsfeld et al.'s (Lazarsfeld, P.F., Berelson, B., Gaudet, H., 1944. The People's Choice. Duell, Sloan, and Pearce, New York) classic work on communication flows, we devise an asymmetric transmission model of expectation formation. This model assumes that the expectations of the less informed segments within the electorate are influenced by the expectations of more informed groups but that the opposite does not hold. We use educational differences as a proxy for information heterogeneity. A vector autoregression (VAR) analysis on monthly surveys of inflation expectations supports the asymmetric transmission hypothesis.     

Integrity Systems,Values, and Expectations: Explaining Differences in the Extent of Corruption in Three Spanish Local Governments

Our article attempts to explain the differences in the extent of corruption related to urban planning in three Spanish local settings, all of them being important touristic resorts: Marbella, a municipality in the Costa del Sol with a very high level of corruption; Lanzarote, in the Canary islands with a high incidence of corruption despite its pioneering role in establishing innovative policies to limit urban (touristic) growth; and Menorca, in the Balearic Islands where corruption has been very low. We argue that the explanations focusing on the different features of the local integrity systems (LISs) face difficulties to account for the variations in the incidence of corruption across these Spanish municipalities: despite some interesting differences, the LIS of the cases considered is basically quite similar. Thus, we turn to the analysis of social values and social expectations on the political system by local citizens, testing whether a different set of citizens’ values and expectations on the behavior of local decision makers may explain this local variation in corruption practices. The article presents the results of a public opinion survey on values and expectations administered in the three cases. Against our expectations and the literature on the topic, no significant difference in shared social values and expectations has been found. The article shows that, as for an empirically tested explanation of the cross-local variations in the degree of urban corruption in Spain, the jury is still out.     

Amazonian peasant livelihood differentiation as mutuality-market dialectics

ABSTRACT

Economistic approaches to the study of peasant livelihoods have considerable academic and policy influence, yet, we argue, perpetuate a partial misunderstanding – often reducing peasant livelihood to the management of capital assets by rational actors. In this paper, we propose to revitalize the original heterodox spirit of the sustainable livelihoods framework by drawing on Stephen Gudeman’s work on the dialectic between use values and mutuality on the one hand, and exchange values and the market on the other. We use this approach to examine how historically divergent mutuality-market dialectics in different Amazonian regions have shaped greater prominence of either extractivism or agriculture in current livelihoods. We conclude that an approach centered on the mutuality-market dialectic is of considerable utility in revealing the role of economic histories in shaping differential peasant livelihoods in tropical forests. More generally, it has considerable potential to contribute to a much-needed re-pluralization of approaches to livelihood in academia and policy.
