- This document summarises the talks and discussions happened during the VBSCan Split17 workshop, the first general meeting of the VBSCan COST Action network. This collaboration is aiming at a consistent and coordinated study of vector-boson scattering from the phenomenological and experimental point of view, for the best exploitation of the data that will be delivered by existing and future particle colliders.

Polarimetric Properties of Event Horizon Telescope Targets from ALMA

Tidskriftsartikel (refereegranskat)abstract
- We present the results from a full polarization study carried out with the Atacama Large Millimeter/submillimeter Array (ALMA) during the first Very Long Baseline Interferometry (VLBI) campaign, which was conducted in 2017 April in the lambda 3 mm and lambda 1.3 mm bands, in concert with the Global mm-VLBI Array (GMVA) and the Event Horizon Telescope (EHT), respectively. We determine the polarization and Faraday properties of all VLBI targets, including Sgr A*, M87, and a dozen radio-loud active galactic nuclei (AGNs), in the two bands at several epochs in a time window of 10 days. We detect high linear polarization fractions (2%-15%) and large rotation measures (RM > 10(3.3)-10(5.5) rad m(-2)), confirming the trends of previous AGN studies at millimeter wavelengths. We find that blazars are more strongly polarized than other AGNs in the sample, while exhibiting (on average) order-of-magnitude lower RM values, consistent with the AGN viewing angle unification scheme. For Sgr A* we report a mean RM of (-4.2 0.3) x 10(5) rad m(-2) at 1.3 mm, consistent with measurements over the past decade and, for the first time, an RM of (-2.1 0.1) x 10(5) rad m(-2) at 3 mm, suggesting that about half of the Faraday rotation at 1.3 mm may occur between the 3 mm photosphere and the 1.3 mm source. We also report the first unambiguous measurement of RM toward the M87 nucleus at millimeter wavelengths, which undergoes significant changes in magnitude and sign reversals on a one year timescale, spanning the range from -1.2 to 0.3 x 10(5) rad m(-2) at 3 mm and -4.1 to 1.5 x 10(5) rad m(-2) at 1.3 mm. Given this time variability, we argue that, unlike the case of Sgr A*, the RM in M87 does not provide an accurate estimate of the mass accretion rate onto the black hole. We put forward a two-component model, comprised of a variable compact region and a static extended region, that can simultaneously explain the polarimetric properties observed by both the EHT (on horizon scales) and ALMA (which observes the combined emission from both components). These measurements provide critical constraints for the calibration, analysis, and interpretation of simultaneously obtained VLBI data with the EHT and GMVA.

- Purpose - The purpose of this paper is to investigate the characteristics of actors that allow them to relate to others actors in the system through shared intentionality (orientation) and the nature of the A4A relationship and the results that such interactions bring to the emergent system based on this shared purpose (finality). Design/methodology/approach - The topic is approached by theoretical analysis and conceptual development of three integrative frameworks: the sociological perspective, service-dominant logic and a particular perspective of system thinking: the viable system approach (vSa). Findings - The A4A relationships involve value co-creation based on actors integrating their resources and acting with intentionality to obtain value by providing benefits to other parties and by belonging to the emergent viable system; actor acts for other actors directly involved in the relationship generating positive effects for the whole system in which it is contextualized. Research limitations/implications - Future empirical research might better support findings. Social implications - Many social implications deriving from an augmented role of actors engaged within social relationships in co-creation exchanges. From the title of the paper A4A over on the manuscript describes numerous social inferences of actors in co-creation. Originality/value - A4A is a relationship formed by actors that interact for the benefit of the whole system in which are involved. They find own benefit from the benefit created for the system in which they live and act. In A4A relationships the value of the single actor comes from the participation to the viability of the whole system.

Measuring place branding strategy implementation

Konferensbidrag (refereegranskat)abstract
- Place branding caught significant attention both among researchers and practitioners in the last decades, moving from corporate branding and marketing concept to a more multidisciplinary approach. Being an influential part of new public management, urban planning, and governance place branding concept became more complex and broader.Place branding is considered as a way for places to differentiate themselves addressing concrete actions highlighting identity and communicating values to beneficiaries and targets. Even if the literature and practitioners share frameworks and processes to design place branding strategy, problems emerge with the implementation of plans. The question on how to measure place branding strategy implementation remains. A paradox occurs when measurement models and indicators are fragmented or too broad and complicated. Moreover, these models are mostly focused on measuring results and outcomes of events and campaigns, confusing tactical with strategic results. It is necessary to search for measurement systems and indicators focusing on the day-by-day communication and implementation of place branding values and identity coming from the concrete activities, approaches and decisions of place brand primary stakeholders.This study aims to discuss the nature and possibilities of identifying a measurement model of place branding strategy implementation and to propose a framework for collecting qualitative and quantitative data among the primary stakeholders of a place. The study's conceptual framework adopts place branding and identity concepts to identify measurement indicators of place branding strategy implementation. In particular, the role of primary stakeholders is recognized in their strategy implementation and place identity diffusion.Economic and not economic activities, organizations, and citizens that everyday work and live the place can communicate and implement the place branding strategy. For this reason, this work presents a selection of indicators, mainly based on secondary data, helpful to identify if primary stakeholders of a place are on the right track in communicating and implementing the place branding strategy.Different from the actual existing models about place branding assessment, this study focuses on the primary stakeholders and their interpretation, communication, and implementation of the place branding strategy. Because place branding is a strategy to highlight place identity and values to beneficiaries and targets, the work selects indicators to measure the compatibility between the place identity and values and the effective communication, investments, and actions on the ground coming from the primary stakeholders.The research makes it possible to measure the alignment between the place branding strategy and place stakeholders’ practices, aiding desired positioning and amplifying brand value dissemination. Researchers and practitioners can obtain valuable elements to understand if strategy implementation, stakeholders’ involvement and even the communication is going toward the right direction identified by the place branding. It is a process useful at the end of the place branding process but even in progress.
