Latvia. Human Development Report 2010/2011: National identity, Mobility and Capability

2011

The 2010/2011 report was produced under the auspices of the national research programme „National Identity”. The job of the report is to survey the content of individual national belonging in the context of human development. The report particularly focuses on emigration issues, because human development is weakened by a reduction in the size of the country’s population. The fact that people are moving to other countries shows that there is an endless competition among identities, as well as a transformation of those identities. The report also reveals the set of circumstances and techniques (the ability to act) which facilitate links between an individual and a location or region. The firs…

Distribution of sea urchins living near shallow water CO2 vents is dependent upon species acid-base and ion-regulatory abilities.

2013

To reduce the negative effect of climate change on Biodiversity, the use of geological CO2 sequestration has been proposed; however leakage from underwater storages may represent a risk to marine life. As extracellular homeostasis is important in determining species' ability to cope with elevated CO2, we investigated the acid-base and ion regulatory responses, as well as the density, of sea urchins living around CO2 vents at Vulcano, Italy. We conducted in situ transplantation and field-based laboratory exposures to different pCO2/pH regimes. Our results confirm that sea urchins have some ability to regulate their extracellular fluid under elevated pCO2. Furthermore, we show that even in cl…

Furthermore we show that even in closely-related taxa divergent physiological capabilities underlie differences in taxa distribution around the CO2 vent. It is concluded that species distribution under the sort of elevated CO2 conditions occurring with leakages from geological storages and future ocean acidification scenarios may partly be determined by quite subtle physiological differentiation.Mediterranean seaBenthosAnimalsSeawater14.

Women’s empowerment and child mortality: the case of Bangladesh

2018

Bangladesh is the Southern Asian country that has been experiencing the highest absolute decline in the Under Five Mortality Rate in the past 15 years. This paper focuses on the importance of women’s education and empowerment variables in explaining this extraordinary result. We use a twolevel multilevel logistic regression to take into account the great differences among territorial communities in terms of child mortality reduction. It emerges that the importance of woman’s empowerment - measured as individual and as mother - remains relevant even when the context is considered. A sensitivity analysis has been conducted to test the relevance of different indicators of female empowerment.

EMI Analysis in Electrical Drives under Lightning Surge Conditions

2012

In this paper, a complete model of a power drive system including the earth electrodes is proposed to evaluate electromagnetic conducted interference due to lightning pulses. Circuit model of a power drive system is joined with a full-wave approach for the simulation of the time behavior of the grounding system. The proposed model enables to predict the electromagnetic conducted interference generated in the power drive system when lightning conditions involve the earth electrodes.

Electric Power Quality Evaluation in the Presence of Electromagnetic Emissions

2013

The measurements for the assessment of the electric power quality are often carried out in hostile electromagnetic environments. The aim of the paper is analyzing if and how both radiated and conducted electromagnetic emissions can disturb the measurement system used to quantify these disturbances. To achieve the target, an experimental approach is proposed, which, by means of a simple and fast test, allows establishing if the real electromagnetic environment, where power quality analysis is performed, can alter the measurements. © 2013 IEEE.

Immunity of a Virtual Instrument to conducted electromagnetic disturbances

2004

In the paper the performances of the Virtual Instruments under conducted electromagnetic disturbances are investigated, in order to find out if and how their metrological characteristics change with respect to the ones measured in absence of electromagnetic threats. The analysis is carried out by means of experimental tests, subjecting the AC power port of the systems under test to the conducted disturbances considered by the IEC-61326 standard and following the test procedures prescribed in the IEC-61000-4-series standards. The results show that the tested measurements instruments are sufficiently immune to these disturbances, since no variations of the distinctive parameters have been obs…

In this article the fi rst results of the performance analysis of the photovoltaic glassblock are given. The photovoltaic glassblock is an innovative product which integrates third generation solar cells (DSSC) invented for the construction of translucent building envelopes energetically effi cient and “active” able to reduce the energy consumption in buildings and to produce at the same time green energy. The analysis was conducted on four different hypotheses of integration through numerical simulations in order to evaluate the energy absorption and the optical performance of the device. The software simulations represent a fi rst step for the understanding of the performance of the element and prelude to an experimental analysis session. The results of a research conducted about national and international patents publications on the DSSC technology and its applications will be illustrated too. The data collected during this research had been organized in a digital database.Settore ICAR/10 - Architettura Tecnica

Diagnosis and therapeutic management of primary headache in an emergency setting

2013

Introduction and aim: Much headachers are under or mis-diagnoses and data regarding the proportion of patients attending an emergency department (ED) because of headache are still few. We conducted a retrospective observational study in an ED with the following aims: (a) estimate the proportion of headache attending to an ED (b) to estimate and describe the therapeutic management of primary headache and (c) to assessment the exam most frequently requested. Materials and methods: We collected data regarding patients diagnosed with headache consecutively attending the ED of the University of Palermo between September 2011 and March 2012. The study was approved by the ethics committee. Results: Between the semester evaluated 25110 subjects were admitted to ED headache suffers were equal to 1.6 %. Of these 263 (63.1 %) were woman and 154 (36.9 %). Mean age was 44.2 (DS ± 18.4) years (p = 0.068).According to ED registry headache admission was as follow assigned: 76.5 % with a diagnosis of headache 22.8 % with a secondary headache 0.7 % with Trigeminal Autonomic Cephalgias (TACs). Among those with a primary headache about 36 % of patient did not received a pharmacological treatment. Monotherapy was prescribed less frequently than combination therapy (19.1 vs 44.5 %).In monotherapy the most frequent medication were NSAIDs (28.3 %) benzodiazepines (26.7 %) and dopamine antagonists (11.7 %). Among those with a primary headache a CT scan was performed in the 124 subjects and 111 (34.8 %) had a neurologist consultation. Discussion: Our data are in line with the one previously reported in literature. The most frequently medication in the Italian ED were NSAIDs benzodiazepines dopamine antagonists and steroids. Neverless our data unlikely can be compared to other study give a snapshot. We believe that much more can be done to improve treatment of primary headache in ED.Settore MED/26 - Neurologia

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
