The World Order is a concept in constant mutation that has lost a lot of what characterized it when it was established with the Peace of Westphalia. The conflicts also went through changes. They lost its State distinctiveness and became dispersed and chaotic due to multipolarization. These two concepts share some connections and both dissociated from their traditional definition. This paper aims to establish a connection between the contemporary World Order and the conflicts evolution. The threats to the stability of the World Order contribute to the current disorder and reflects how the conflicts distanced themselves from the clausewitzian battles. To understand how these threats impact the World Order stability and evince the conflicts evolution two cases of study were selected: the nuclear proliferation in Iran and the crisis in Ukraine. These two examples will help establishing the link between the contemporary World Disorder and the conflicts evolution.

This chapter aims at presenting and discussing credible online recruitment eliciting techniques targeting scientific purposes adjusted to the digital age. Based on several illustrations conducted by the author within the framework of both quantitative and qualitative inquiries, this chapter critically explores the digital ethos in three main challenges faced when dealing with online recruitment for scientific purposes: entering the normality of the everyday life, entering the idiosyncrasy of multicultural lives, and entering the chaos of busy lives. By the end, a toolbox for establishing and evaluating (dis)credibility within online recruitment strategies is presented. Moreover, it is argued that success of data collection at the present time in online environments seems to rely as ever on internal factors of the communication process vis-à-vis e-mail content, design and related strategies.

As key prey, the wild rabbit downsize constitutes a major drawback on the endangered Iberian lynx (Lynx pardinus) re-introduction in the Iberia. Several captive breeding units mostly located in Alentejo, endeavour the wild rabbit repopulation of depleted areas assigned for the lynx re-introduction. Here we report an RHDV2 outbreak that occurred in early 2016 in a wild rabbit captive breeding unit located in Barrancos municipality. The estimated mortality rate between March and April 2016 was approximately 8.67%. Anatomopathologic examination was carried out for 13 victimized rabbits. Molecular characterization was based on the complete vp60 capsid gene. The 13 rabbit carcasses investigated showed typical macroscopic RHD lesions testing positive to RHDV2- RNA. Comparison of the vp60 nucleotide sequences obtained from two specimens with others publically available disclosed similarities below 98.22% with RHDV2 strains originated in the Iberia and Azores and revealed that the two identical strains from Barrancos-2016 contain six unique single synonymous nucleotide polymorphisms. In the phylogenetic analysis performed, the Barrancos-2016 strains clustered apart from other known strains, meaning they may represent new evolutionary RHDV2 lineages. No clear epidemiological link could be traced for this outbreak where the mortalities were lower compared with previous years. Yet, network analysis suggested a possible connection between the missing intermediates from which the strains from Barrancos 2013, 2014 and 2016 have derived. It is therefore possible that RHDV2 has circulated endemically in the region since 2012, with periodic epizootic occurrences. Still, six years after its emergence in wild rabbits, RHDV2 continues to pose difficulties to the establishment of natural wild rabbit populations that are crucial for the self-sustainability of the local ecosystems.

O presente trabalho tem como objecti- vo mostrar os resultados preliminares do estudo de prospecção geoarqueológica realizado no povoado do Outeiro do Circo. O trabalho consistiu no cruzamen- to de dois métodos de prospecção geofísica: georradar e magnetometria. Para concretizar o objectivo da missão realizaram-se ensaios dos dois métodos em áreas dis- tintas. O processamento dos dados registados permitiu identificar estruturas enterradas, interpretadas como vestígios da muralha que rodeava o povoado e de edifíci- os que terão existido no seu interior. Essas estruturas serão em breve confirmadas pelas escavações arque- ológicas em curso.
