Poderes fácticos mediáticos: una agenda de investigación

Based on the recognition of the importance of the commonly referred to as factual powers in Mexico’s political life, and specifically in the media power, the author calls upon our attention the insufficient analysis and research on the subject and underscores the need to overcome this deficit by systematically and rigorously approaching it as a subject of inquiry and as part of a research agenda. This article brings to the fore the basic points of such an agenda and proposes a multidisciplinary analytical approach to develop it. The author argues that the studies’ findings can be applied to constructing limits for the exercise of media power, which are indispensable for national democratic development.     

Microwave Selective Thermal Development of Latent Fingerprints on Porous Surfaces: Potentialities of the Method and Preliminary Experimental Results

The thermal development of latent fingerprints on paper surfaces is a simple, safe, and chemicals‐free method, based on the faster heating of the substrate underlying the print residue. Microwave heating is proposed for the first time for the development of latent fingerprints on cellulose‐based substrate, in order to add to the thermal development mechanism the further characteristic of being able to heat the fingerprint residues to a different extent with respect to the substrate, due to the intrinsic difference in their dielectric properties. Numerical simulation was performed to confirm and highlight the selectivity of microwaves, and preliminary experimental results point out the great potentialities of this technique, which allowed developing both latent sebaceous‐rich and latent eccrine‐rich fingerprints on different porous surfaces, in less than 30 sec time with an applied output power of 500 W. Microwaves demonstrated more effectiveness in the development of eccrine‐rich residues, aged up to 12 weeks.     

Paving the (Hard) Way for Regional Partnerships: Evidence from Portugal

A fundamental dilemma which troubles advocates of interinstitutional partnerships in regional development pertains to the extent to which partnerships enhance the effectiveness of governance processes and outcomes. This dilemma is particularly relevant in contexts that lack strong cohesive regional development alliances, such as the Portuguese case. This article aims to shed light on the debate regarding the role of partnerships in regional development, drawing on a unique collaborative interinstitutional partnership. It explores the responses to complexity across the different stakeholders, as well as its effects at the formulation and implementation stages of the strategic plans devised to apply for EU funding. Findings suggest that interinstitutional partnerships induce significantly different allocative choices at the agenda-setting. However, the established partnership was unable to cope with the several obstacles that emerged during the implementation, suggesting several vulnerabilities of partnerships, which are explored. Findings suggest the need to reinforce governance mechanisms during the implementation stage.     

Effects of an Alibi Witness’s Relationship to the Defendant on Mock Jurors’ Judgments

Two studies tested the impact of an alibi witness’s relationship to a defendant on the perceived credibility of that witness. In the first study, 291 mock jurors estimated the frequency with which individuals would invent alibis, the frequency they themselves would do so, and the frequency of interpersonal contact among individuals of varying relationships. The degree of relationship between an alibi witness and a defendant remained a predictor of witness credibility when contact frequency was controlled. In the second study, 512 mock jurors were randomly assigned to case scenarios. Skepticism toward witnesses who are biologically or affinally related to a defendant was greater than skepticism toward a socially linked witness. Both studies supported predications from kinship theory and reciprocal altruism.
