Direct limits on the $B_s^0$ oscillation frequency
2006
Made available in DSpace on 2022-04-28T20:09:59Z (GMT). No. of bitstreams: 0 Previous issue date: 2006-01-01 We report results of a study of the Bs0 oscillation frequency using a large sample of Bs0 semileptonic decays corresponding to approximately 1fb-1 of integrated luminosity collected by the D0 experiment at the Fermilab Tevatron Collider in 2002-2006. The amplitude method gives a lower limit on the Bs0 oscillation frequency at 14.8ps-1 at the 95% C.L. At Δms=19ps-1, the amplitude deviates from the hypothesis A=0 (1) by 2.5 (1.6) standard deviations, corresponding to a two-sided C.L. of 1% (10%). A likelihood scan over the oscillation frequency, Δms, gives a most probable value of 19ps…
Leveraging Collaborative Governance: How Co-production Contributes to Outcomes and Public Value in a Small Town
2020
Collaborative governance is increasingly considered an effective approach to improve outcomes and public value. This chapter focuses on co-production as an instrument to implement collaborative governance at local level. It is not uncommon that small towns develop co-production processes to deliver cultural and touristic services. Out of a literature review, the study develops a Dynamic Multidimensional Performance Management framework to explore the impact of co-production on community outcomes. To this end, this chapter discusses the case “Museo Civico di Castelbuono (MCC)”,which concerns the co-production process of the guided tour of the museum’s venue. The resulting model provides insi…
Innovation Management Practices in Production-Intensive Service Firms
2015
Postprint version of the article. This paper posits that innovation management practices are contingent upon the type of industry, and examines the innovation management practices in a distinctive set of service firms: production-intensive service firms. Production-intensive services are standardised services produced at a large scale. These services have received little attention from prior comprehensive qualitative innovation management practices research. The examination in this paper is based on in-depth interviews with 21 key-employees in five large Scandinavian production-intensive service firms. The results revealed a number of innovation management practices specific to production-i…
Leisure, Social Capital and Life Turns in Deviant Youth
2017
The production of social capital in a specific area of everyday life such as leisure time and the different socio-cultural contexts it is experienced in is a very interesting research issue, especially in the light of certain pecific meanings of the notion of social capital, such as Bourdieu's or, more recently, Putnam's. Nonetheless, this research issue is scarcely taken into consideration in Italy. Albeit inexaustively, this paper intends to introduce this issue starting from a brief review on the generation of social capital in youth's leisure time contexts. In the first paragraph I problematize the notion of social capital as referred to leisure time "contexts" as well as analyze either…
Economic Allocation in Life Cycle Assessment The State of the Art and Discussion of Examples
2012
Summary This article examines methods for analyzing allocation in life cycle assessment (LCA); it focuses on comparisons of economic allocation with other feasible alternatives. The International Organization for Standardization's (ISO) guideline 14044 indicates that economic allocation should only be used as a last resort, when other methods are not suitable. However, the LCA literature reports several examples of the use of economic allocation. This is due partly to its simplicity and partly to its ability to illustrate the properties of complex systems. Sometimes a price summarizes complex attributes of product or service quality that cannot be easily measured by physical criteria. On th…
Stochastic frontier models using R
2020
Abstract The production function is usually assumed to specify the maximum output obtainable, from a given set of inputs, describing the boundary or frontier of the obtainable output from each feasible combination of input; it relates the production process of individual units to the efficient border of the production possibilities. The measure of the distance of each unit from the border is the most immediate way to assess its (in)efficiency. However, the production function is not generally known, but it has only a set of information on each production unit and it is therefore essential to develop techniques to estimate the production frontier. Starting from the packages already developed…
Toward solutions for energy efficiency
2020
Abstract The tariff setting for district heating (DH) services is a hard regulatory procedure. This chapter is devoted to development of the simple but sufficiently accurate methodology for fast and objective evaluation of the actual costs of DH to optimize the regulatory process and to set adequate tariffs on heat production and transmission. The developed methodology is based on the data sets of Latvian DH providers, but the methodological principles are applicable in another area too. Investigation of heat production drivers and following simulation revealed the key performance indicators (KPIs): fuel type and price. By usage of intelligent benchmarking data mining methods and mathematic…
Modeling musical attributes to characterize ensemble recordings using rhythmic audio features
2011
In this paper, we present the results of a pre-study on music performance analysis of ensemble music. Our aim is to implement a music classification system for the description of live recordings, for instance to help musicologist and musicians to analyze improvised ensemble performances. The main problem we deal with is the extraction of a suitable set of audio features from the recorded instrument tracks. Our approach is to extract rhythm-related audio features and to apply them for regression-based modeling of eight more general musical attributes. The model based on Partial Least-Squares Regression without preceding Principal Component Analysis performed best for all of the eight attribu…
ECONOMIC EVALUATION OF MEDITERRANEAN SEA BASS FARMS ACCORDING TO MARKET TYPOLOGY
2014
Italy represents one of the main production countries of European sea bass and, in this context, Sicilian fish farms play a key role. Since in the last years the economic development has led to an increasingly globalized market, in this paper it has been carried out an economic evaluation of two Sicilian European sea bass farms according to the market typology in which their product is allocated: competitive and oligopolistic market. Moreover, a sensitivity analysis allows to understand how market prices could influence farm economic performances. Results showed higher profit for farm that sold product in oligopolistic market, even if sensitivity analysis highlighted that both farms were ve…
Economic evaluation of PDO introduction in Sicilian orange farms
2014
The south-western part of Sicily is the largest Italian production area of Navel oranges where in 2008 it was established the Arancia di Ribera Prot ected Designation of Origin (PDO). The aim of the paper was to ana lyze the effect that the PDO introduction determined on farm profitability and sustainability. To this end, it was carried out an economic analysis on some representative orange farms of PDO area.
