A geometric street scattering channel model for car-to-car communication systems

2011

This paper presents a geometric street scattering channel model for car-to-car (C2C) communication systems under line-of-sight (LOS) and non-LOS (NLOS) propagation conditions. Starting from the geometric model, we develop a stochastic reference channel model, where the scatterers are uniformly distributed in rectangles in the form of stripes parallel to both sides of the street. We derive analytical expressions for the probability density functions (PDFs) of the angle-of-departure (AOD) and the angle-of-arrival (AOA). We also investigate the Doppler power spectral density (PSD) and the autocorrelation function (ACF) of the proposed model, assuming that the mobile transmitter (MT) and the mo…

Il Polar prima del Polar: il poliziesco italo-americano tra fine Ottocento e gli anni Trenta del Novecento

2018

Tra la fine dell’Ottocento e gli anni Trenta del Novecento, alcuni Italiani immigrati negli Stati Uniti – quali, fra gli altri, Bernardino Ciambelli, Italo Stanco, Garibaldi Marto Lapolla, Louis Forgione, nonché il sodalizio letterario costituito da Michael Fiaschetti e Prosper Buranelli – si sono cimentati nel genere del poliziesco con alcuni testi che, partendo da alcune delle caratteristiche tipiche del Mystery, quali la serializzazione e l’incardinamento della fabula in uno specifico contesto urbano, insieme ad alcuni degli elementi caratteriali dei personaggi dell’Hard boiled non perdono mai di vista la peculiare ‘missione’ di denuncia politica, economica e sociale. Facendo del problem…

Higher Brain Centers for Intelligent Motor Control in Insects

2011

The higher control of orientation, walking and gap climbing behavior in the fruit fly Drosophila is studied by neurogenetic means. An insect brain model is presented for the control of object approaches. The model comprises learning abilities of flies at two different time scales. A short-term orientation memory allows for the continued approach of objects that disappeared from sight. Flies can come back to the still invisible object even after a detour to a distracter object. A long-term memory allows for the storage of experience with particular types of objects in order to trigger avoidance behavior in the future instead of the default approach behavior. Moreover, we provide evidence tha…

A Closer Look at First Sight: Social Relations Lens Model Analysis of Personality and Interpersonal Attraction at Zero Acquaintance

2011

Based on a new theoretical framework—the Social Relations Lens Model—this study examined the influence of personality on real–life attraction at zero acquaintance. A group of psychology freshmen ( N = 73) was investigated upon encountering one another for the first time. Personality traits, attraction ratings and metaperceptions were assessed using a large round–robin design (2628 dyads). In line with our model, personality differentially predicted who was a liker and who expected to be liked (perceiver effects), who was popular and who was seen as a liker (target effects), as well as who liked whom and who expected to be liked by whom (relationship effects). Moreover, the influence of pers…

“Out of Sight, Out of Mind?”: The Role of Physical Stressors, Cognitive Appraisal, and Positive Emotions in Employees’ Health

2017

This study analyzes the mediating role of the appraisal of environmental stressors in the relationship between physical characteristics in the offices and health symptoms. It also studies the moderating role of positive emotions in the relationship between physical characteristics and the appraisal of environmental stressors using a diary study on 59 office workers ( n = 432 time points) and sensor data. The results show that the appraisal of environmental stressors mediates the relationship between physical office characteristics and health symptoms, emphasizing the important link of stress appraisal in the stressors–strain relationship. The results also show that positive emotions modera…

Images of the future for a circular economy : The case of Finland

2022

A transition from a linear to a circular economy (CE) is one of the key solutions to the sustainability crisis. A CE requires new mental models and insights, especially of a desirable future towards which to move. A CE aims at making better use of resources and jointly considers economic, environmental and social sustainability aspects in the long run. The objective of this study is to develop alternative images of the future for CE in Finland in 2050. The study was performed using qualitative research methods and covers extensive data from 61 interviews with experts. We analysed the data using qualitative content analysis. Four alternative images of the future were generated: A circular su…

La Valle dei Templi in epoca medioevale. Caratterizzazione antropologica e paleopatologica delle sepolture antistanti in Tempio della Concordia

2021

Riassunto ― Il lavoro presenta i risultati delle analisi bio-archeologiche effettuate su resti scheletrici umani rinvenuti in quattordici sepolture di epoca medioevale rinvenute nel Parco Archeologico della Valle dei Templi di Agrigento (Sicilia). L’obiettivo è stato l’acquisizione delle informazioni necessarie per la ricostruzione del profilo biologico di ciascun individuo, al fine di determinarne il sesso, la stima dell’età biologica alla morte, la stima della statura e la valutazione delle patologie e degli indicatori di stress occupazionale mediante le correnti metodologie e tecniche diagnostiche di tipo antropologico. Sebbene il cattivo stato di conservazione di alcuni individui non ne…

Backcasting for desirable futures in Finnish forest-based firms

2020

Purpose In Finland, new forest-based sector (FBS) businesses are seen as important for the transition to the circular bioeconomy. The purpose of this study is to explore the transition of Finnish FBS companies to new business models. The aim is to understand how FBS companies define their ideal future states and related business models for the year 2030. Design/methodology/approach This study uses thematic interviews with managers from various FBS firms and companies from interfacing sectors. In the interviews, the key idea of backcasting was pursued when respondents discussed the desirable future states of their business. Findings The effort to achieve growth of the business and the appea…

Building on Entrepreneurs’ Leadership through ‘Lean’ and Dynamic Performance Management Systems in Small and Micro Firms. Challenges and Missed Oppor…

2014

This paper frames the potential benefits of ‘lean’ and dynamic performance management (PM) systems for small and micro enterprises. In this context, the ‘lean’ attribute is used to characterize a different approach in applying PM to small firms, in respect to larger organizations. In fact, such systems may exploit the entrepreneur’s tacit knowledge and build on leadership, by incorporating individual attributes into organizational routines. Related to small and micro firms, direct experience and case-studies suggest that their sudden crises and demises are often a product of gradual – internal and external – phenomena that entrepreneurs are not enabled to selectively and promptly detect and…
