A Precise Measurement of the Tau Lepton Lifetime

1996

The tau lepton lifetime has been measured using three different methods with the DELPHI detector. Two measurements of one-prong decays are combined, accounting for correlations, giving a result of \tau_\tau = 291.8 \pm 3.3 \mbox{ (stat.)} \pm 2.0 \mbox{(sys.) fs} while the decay length distribution of three-prong decays gives the result \tau_{\tau} = 286.7 \pm 4.9 \mbox{ (stat.)} \pm 3.3 \mbox{ (sys.) fs}. Combining the results presented here with previous DELPHI measurements, we get \tau_{\tau} = 291.4 \pm 3.0 fs and find that the ratio of the coupling constant for tau decay relative to that for muon decay is 0.990 \pm 0.009, compatible with lepton universality.

Cultural institutions as agents of urban and community regeneration in the (post-)pandemic city. The case of the «Laboratorio Zen Insieme» in Palermo

2022

Although all cities in the world have been affected by the COVID-19 pandemic, its impacts on the territories, yet to be understood, are unevenly distributed, revealing extremely varied imbalances depending on the places. However, it is clear that the virus and its variants have aggravated pre-existing socio-spatial inequalities, creating new ones and bringing attention back to those implications between space, planning, public health and citizenship that are at the origins of contemporary urbanism. In a reference framework in which the crisis is globalized but unequal and in the absence of a welfare system capable of responding to the urgencies of the most marginalized social contexts and g…

Olsen 2018Settore ICAR/21 - UrbanisticaSettore M-GGR/01 - GeografiaSacco and Blessi 2009). In the current (post-) pandemic context and through the lens of a southern European perspective the purpose of this article is to critically reflect about the role of culture as possible vehicle of urban and community regeneration. In particular we will focus on the activities of the no profit organization «Laboratorio Zen Insieme» in ZEN2 one of the last large popular and peripheral neighborhoods built in Palermo at the end of 80s in order to explore and understand how cultural practices work as agent of urban and social transformation capable of addressing emerging issues especially in the pandemic scenario we are experiencing. Thecasestudy has been conducted through analysis of documents participative observations (Honer and Hitzler 2015) and qualitative in-depth interviews with key actors involved in the conception organization and management of the activities carried out by Laboratorio Zen Insieme with representatives of local institutions and non-formal conversations with participants of the workshops heldin the neighborhood. The experience we narrate finds that cultural practices have re-conceptualized their design and functions as strategies of urban and community regeneration and at the same time have contributed to answer to emergent issues in developing proximity and local based strategies facing up to problems inherent civil rights educationalpoverty socio-spatial justice and have changed the image and identity of urban places they inhabit.In this sense the research provides a framework for development of strategies and legitimization for cultural practices and a point of discussionabouttheirrolein urban development.Although all cities in the world have been affected by the COVID-19 pandemic its impacts on the territories yet to be understood are unevenly distributed revealing extremely varied imbalances depending on the places.

In a reference framework in which the crisis is globalized but unequal and in the absence of a welfare system capable of responding to the urgencies of the most marginalized social contexts and groups a response to the new social and individual needs has been offered by cultural institutions that play a role of territorial agency often independently or in the absence of political institutions. Far from the idea of entertainment and divertissement it is in fact increasingly clear how the practices of cultural innovation experimenting with various forms of action and participation can in some cases play a fundamental role in the processes of social cohesion and community building representing an antidote to the worsening of the phenomena of marginalization and socio-spatial inequalities within cities and territories (Colantonio and Dixon 2011

The location of an international logistics center in Poland as a part of The One Belt One Road Initiative

2019

Background: The One Belt One Road initiative opens up many development opportunities for Central and Eastern European countries, some related to the possible construction of a logistics center in this area. For Poland, such an investment would also bring many benefits, not only due to infrastructure development, but also through acceleration of economic growth and job creation. In this context, the crucial issue becomes, what should be the role of an international logistics center and where should it be located. Due to the novelty of the subject, there is a shortcoming of scientific papers related to this issue. The scientific goal of the present paper is to fulfill the gap and to address …

Unity in Discourse, Diversity in Practice: The One Person One Language Policy in Bilingual Families

2013

When parents with different first languages have a child, and want the child to become bilingual in both languages, many parents adopt the one person – one language (OPOL) strategy. This chapter uses nexus analysis (Scollon R, Scollon SW, Nexus analysis. Discourse and the emerging internet. Routledge, London, 2004) to carry out a discourse analysis of ways in which this strategy is motivated by parents and ways it is enacted in conversations between parents and children, in three Swedish-Finnish bilingual families with 3–4 year old children in Finland. We also look at how the children participate in the negotiation of family language policy. Parents were interviewed about their own language…

The Big Meaning of Small Messages: The Use of WhatsApp in Intergenerational Family Communication

2018

This study explores the use of WhatsApp instant messenger in extended families in two countries, Finland and Italy, that represent different family and communication cultures. Qualitative research material was collected in 2014/2015 from families consisting of three or more generations and living either in the same or different households. A directed approach to qualitative content analysis was applied in the analysis of the research data. The results of the study show that WhatsApp is considered to facilitate family interaction across generations. The success of WhatsApp in the family context accounts for two main factors: first, for the possibility to reach the whole family at once; and s…

Expansion of a quantum gas released from an optical lattice

2008

We analyze the interference pattern produced by ultracold atoms released from an optical lattice. Such interference patterns are commonly interpreted as the momentum distributions of the trapped quantum gas. We show that for finite time-of-flights the resulting density distribution can, however, be significantly altered, similar to a near-field diffraction regime in optics. We illustrate our findings with a simple model and realistic quantum Monte Carlo simulations for bosonic atoms, and compare the latter to experiments.

Generalised Kronig-Penney model for ultracold atomic quantum systems

2014

We study the properties of a quantum particle interacting with a one dimensional structure of equidistant scattering centres. We derive an analytical expression for the dispersion relation and for the Bloch functions in the presence of both even and odd scattering waves within the pseudopotential approximation. This generalises the well-known solid-state physics text-book result known as the Kronig-Penney model. Our generalised model can be used to describe systems such as degenerate Fermi gases interacting with ions or with another neutral atomic species confined in an optical lattice, thus enabling the investigation of polaron or Kondo physics within a simple formalism. We focus our atten…
