Internet Users, Privacy Concerns and Attitudes towards Government Surveillance - An Exploratory Study of Cross-Cultural Differences between Italy and the United States
Beam Test Results of the BTeV Silicon Pixel Detector
The results of the BTeV silicon pixel detector beam test carried out at
Fermilab in 1999-2000 are reported. The pixel detector spatial resolution has
been studied as a function of track inclination, sensor bias, and readout
threshold.Comment: 8 pages of text, 8 figures, Proceedings paper of Pixel 2000:

Performance of prototype BTeV silicon pixel detectors in a high energy pion beam
The silicon pixel vertex detector is a key element of the BTeV spectrometer.
Sensors bump-bonded to prototype front-end devices were tested in a high energy
pion beam at Fermilab. The spatial resolution and occupancies as a function of
the pion incident angle were measured for various sensor-readout combinations.
The data are compared with predictions from our Monte Carlo simulation and very
good agreement is found.Comment: 24 pages, 20 figure
Beam Test of BTeV Pixel Detectors
The silicon pixel vertex detector is one of the key elements of the BTeV
spectrometer. Detector prototypes were tested in a beam at Fermilab. We report
here on the measured spatial resolution as a function of the incident angles
for different sensor-readout electronics combinations. We compare the results
with predictions from our Monte Carlo simulation.Comment: 7 pages, 5 figures, Invited talk given by J.C. Wang at "Vertex 2000,

Relazioni consulenziali "di processo"
Le relazioni consulenziali \u201cdi processo\u201d sono pratiche trasformative finalizzate allo sviluppo delle organizzazioni e delle persone. Sono fondate sul
presupposto che facilitare l\u2019apprendimento abbia a che fare con lo sviluppo della consapevolezza e il supporto riguardo al metodo (processo) piuttosto
che sulla trasmissione di contenuti o l\u2019apprendimento di una soluzione. Nel lavoro presentato viene problematizzato il concetto di consulenza di processo
attraverso una riflessione sui possibili assunti che orientano le prassi consulenziali. In particolare si fa riferimento alle possibili teorie implicite del
consulente per ci\uf2 che riguarda l\u2019organizzazione, il processo, l\u2019apprendimento, la relazione. Nell\u2019ipotesi dell\u2019Autore queste teorie implicite danno vita a
diverse pratiche di consulenza, quindi \ue8 opportuno che vengano chiarite ed esplicitate

La transizione intergenerazionale nelle piccole e medie imprese (PMI): un'analisi della letteratura sull'argomento
The present study constitutes a review relative to the theoretical references present in literature on the topic of the transfer of business. The scope is to put in evidence the complexity of the entire successory process, characterizing some studies that better than others can supply useful interpretative keys to us to the positive resolution of the phenomenon considered. To face in an integrated way this delicate organizational phase demands necessarily the punctual decode of the single strongly interconnected aspects and the necessity to comprise the detailed problematics of the involved protagonists: the enterprise, the family, the entrepreneur, the heir and all the persons who work in company
Privacy calculus model in e-commerce: a study of Italy and the United States
This study examines cross-cultural differences beliefs related to e-commerce use
for Italy and the United States. We argue that for both cultures, the user’s
decision to make an online purchase is simultaneously influenced by a set of
contrary factors. These include decision facilitators such as propensity to trust
and institutional trust, and decision inhibitors such as perceived risk and privacy
concerns. We argue that substantial cultural differences exist that affect the
above factors and the relationships among them. We use Hofstede’s cultural
theory and Fukuyama’s theory of trust and social capital, along with emic
factors important for the Italian society, to develop the study’s propositions.
The hypotheses were empirically tested using LISREL structural equation
modeling and multigroup analysis. The results revealed that the Italian society
exhibited lower propensity to trust, institutional trust, privacy concerns, and
higher perceived risk. The relationships between institutional trust and ecommerce
use, privacy concerns and e-commerce use, and perceived risk and
institutional trust are all weaker for Italy. The relationship between perceived
risk and privacy concerns is stronger for Italy. The paper’s major contribution is
in validating an important model of e-commerce use across two cultures and
showing the moderating effects of culture
Internet Users' privacy Concerns and Beliefs About Government Surveillance: An Exploratory Study of Differences Between Italy and the United States
The study examines differences in individual’s privacy concerns and beliefs about government
surveillance in Italy and the United States. By incorporating aspects of multiple cultural theories,
we argue that for both countries, the user’s decision to conduct e-commerce transactions
on the Internet is influenced by privacy concerns, perceived need for government surveillance
that would secure the Internet environment from fraud, crime and terrorism, and balancing
concerns about government intrusion. An empirical model was tested using LISREL structural
equation modeling and multigroup analysis. The results support the hypotheses with regard to
direction and relative magnitude of the relationships. Italians exhibit lower Internet privacy
concerns than individuals in the U.S., lower perceived need for government surveillance, and
higher concerns about government intrusion. The relationships among the model constructs
are also different across the two countries. Implications of the findings and directions for future
work are discussed
