“…Relatively high values of Cd, Zn, Mn and Cr were detected in TF, whereas Pb and Ni were only found at station 16. Some studies have reported heavy metals in invertebrates, the dissolved phase and sediments in several coastal sites of the Beagle Channel and Ushuaia Bay (Conti et al 2011(Conti et al , 2012(Conti et al , 2019Duarte et al 2011;Giarratano et al 2010Giarratano et al , 2011, but to our knowledge, there are no metal records in the sector of the shelf that belongs to this area. Higher levels of Pb, Zn, and Fe, and lower levels of Cd and Cu have been reported in the sediments of the BC (Duarte et al 2011) (Table 3), than in the particulate fraction in the present study.…”

A global record of particulated metals on the southwestern Atlantic shelf (Argentine Sea)

The Argentine Sea (Southwestern Atlantic) is one of the most productive ecosystem in the Southern Hemisphere. Research on metals in this region is scarce or null. In this study, we evaluated the concentrations of some metals in the suspended particulate matter (SPM), to provide baseline data that would enable us to understand the role of the SPM in the transport of metals in the Argentine Sea. Sampling was carried out during the austral summer 2016 at 20 stations distributed in the Argentine Sea. Surface seawater samples were collected and then filtered by vacuum through Millipore ® HAWP 04,700 filters (0.45 µm). The samples were acid-digested (HNO 3 and HClO 4 , 5:1) and the metal concentrations were determined with ICP-OES Optima 2100 DV (Perkin Elmer). Significant spatial variations were detected due to the extension of the study area, with the highest levels of metals in the stations next to large urban centers (

“…Deepening these theoretical aspects, norms constitute the behavioral boundaries to contain social action and permit people to discern what is allowed from what is not. According to the VSA, norms configure one of the more stable structural element of the information variety, a concept rooted in the Ashby' requisite variety (1956Ashby' requisite variety ( , 1958 and that expresses the overall knowledge endowment owned by a viable social system at a certain instant t [infVt] ( Barile and Saviano, 2011b;Conti et al, 2019). As the more stable element of the [infVt], the taken-for-granted norms act as a genetic memory of a social system (Hayek, 1952(Hayek, , 1979North, 2006).…”

The paper investigates the complex interaction between technological innovation and norms: a crucial dynamic to facing the severe challenges of the Anthropocene.On the one hand, the sedimentation of norms acts as the genetic memory of a society. Allowing a reduction in the uncertainty of human condition and ensuring greater predictability of human interaction, the set of norms tend to activate a system of constraints that normalize and legitimate technological innovations.On the other hand, technological innovation is one of the most unpredictable and non-linear sources of change. It demands legitimization for what in the past were excluded or prohibited a priori (e.g. behaviors, ethics): this may trigger a “decoupling” process from the extant set of norms. Nevertheless, what decoupling should be legitimized? A wicked problem arises, and forking paths emerge in the socio-economic landscape.Leading the tension between new technology (source of unpredictability) and the taken-for-granted norms (source of predictability) is crucial if the aim is to linking effectiveness and efficiency to viable sustainability. While the (still dominant) cartesian approach considers norms and new technology as separate elements of the social system, system thinking enlightens the interaction between them. This helps to unveil hidden options/feedbacks in the decoupling-recoupling process between technological innovation and the evolution of norms enriching the information variety of the decision-makers (policy makers, citizens, urban planners, etc.).The dynamics that govern this dyad, however, are not linear: norms, in fact, do not have the same reactivity to absorb (recouple) the change triggered by new technologies (decoupling from the extant set of norms).Although the relevance of the issue, it has been often neglected, or at least not taken in the right consideration. Therefore, aiming to investigate this dyadic relationship, the paper focuses on the ambiguous role technology plays in enabling resilience: sometimes it acts as a resilience amplifier; sometimes it is a resilience inhibitor (and even a steel cage); sometimes it provokes an undesirable deviation from the taken-for-granted codified rules.In particular, aiming to contribute in filling this gap, and rooting in the Viable System Approach (VSA), the paper investigates why and how in some cases the interaction between technological innovation and norms leads to resistance towards change or acts as a resilience amplifier in other cases.The paper is structured as follows: after an Introduction underlying the need to understanding the increasing tension between new technology and norms, Section 2 deals with the contribution of the VSA in understanding the social systems; then, rooting in the VSA and moving from the concept of information variety, Section 3 frames the complex interplay between new technology and taken-for-granted norms as one of the most dramatic “resistance-resilience” issue of the Anthropocene era; Section 4 proposes a more comprehensive framework discussing the range “resilience-resistance-vulnerability” and presents final reflections.
