Application of Inverse-Probability-of-Treatment Weighting to Estimate the Effect of Daytime Sleepiness in Obstructive sleep apnea patients

2022

Continuous positive airway pressure (CPAP), the first line therapy for obstructive sleep apnea (OSA), is considered effective in reducing daytime sleepiness. Its efficacy relies on adequate adherence, often defined as >4 hours per night. However, this binary threshold may limit our understanding of the causal effect of CPAP adherence and daytime sleepiness and multilevel approach for CPAP adherence can be more appropriate.

Scritti in onore di Pellegrino Capaldo

2014

La qualità dei servizi è stata riconosciuta come un rilevante aspetto caratterizzante la performance dell’azienda pubblica, analogamente alla capacità di operare secondo criteri di efficienza e nel rispetto dei vincoli di bilancio. Sebbene sia possibile riscontrare alcuni significativi casi di adozione di politiche di customer satisfaction nelle amministrazioni pubbliche italiane, a tutt’oggi il tema presenta significative criticità, specialmente in ordine agli aspetti metodologici e agli strumenti operativi che consentano di integrare dette politiche nel sistema di programmazione e controllo delle aziende che erogano tali servizi. Il presente lavoro adotta una diversa prospettiva di analis…

Settore SECS-P/07 - Economia AziendaleQuality in delivering public services has been recognised as a major issue challenging performance in the public sector as well as the ability to operate effectively and within budget constraints. Empirical findings shown by the literature demonstrate that concrete efforts have been produced towards the evaluation and improvement of satisfaction levels of citizens and other Public Administration’s ‘customers’. However still today this issue portrays many unresolved criticalities particularly concerning the methodological approaches and operative tools to adopt in order to integrate ‘customer satisfaction’ programs with the wider organisational control system in each public administration. This paper adopts a non-conventional view of the ‘customer satisfaction’ concept. This is currently meant as a matter of social reporting or even statistical analysis based on the users’ perceptions on the level of provided services by a given (front office) unit in the public sector. Here an inter-institutional perspective is adopted with a view to map the overall value chain leading to the final product delivered to citizens or the community. Inside this chain tracking the underlying administrative products delivered by back-office units to their ‘internal clients’ in the public administration is recommended as a fundamental step to understand how to improve performance in satisfying citizens’ needs. This should also require a proper link between the administrative units’ goals and performance measures to the desired efficiency and effectiveness of processes leading to the attainment of administrative products providing the basis of the final services delivered to the private sector. Based on first empirical findings from field analysis in the Italian context the paper aims to outline an approach which could assist both politicians and managers to better assess and improve performance according to a customer satisfaction perspective.

Design and analysis of discrete choice experiments for models with response time

2013

Settore SECS-S/02 - Statistica Per La Ricerca Sperimentale E TecnologicaA sector of conjoint analysis (experimental design in marketing research) is made of the so called choice experiments. In choice experiments respondents undergo a questionnaire which is nowadays mostly submitted through the internet. The questionnaire proposes to the respondent a sequence of choice sets each one including two or more profiles being a profile a specific combination of attribute levels. The respondent selects the preferred profile for each choice set. Responses given by a sample of respondents are analysed through suitable methods aimed to eventually find the best combination of attribute levels. One method of analysis adopts the Multinomial Logit (MLN) model. In this article the authors show the results of the MLN analysis compared with another model of analysis which uses an additional response which can be easily recorded by electronically submitted questionnaires. In practice modern survey platforms like “Qualtrics” (the one used for this work) can record the so called “response latency” i.e. the time taken by the respondent to make the choice and select the most preferred profile in the choice set. Thanks to a response latency model further refined in this work it is possible to deduce the relative weight of importance of the profiles for each choice set and respondent. This type of response can be used in place of the dichotomous choice variable in the MLN model. The two models and methods of analysis are deeply compared and it is critically discussed when it is better to use one or the other method. As a result a more reliable estimate of the optimal profile comes up implying lower risks for new investments and marketing decisions.

Evaluation of Daylight Availability for Energy Savings.

2015

Dynamic daylight simulations are very useful instruments in daylighting design process. They allow an in depth analysis of indoor daylight availability levels and define if they are adequate to perform a particular visual task. Their results can be used to design shading devices or lighting control systems and compare different technical solutions. The use of these simulations is likely to spread in the common design practice since some regulations and green building rating systems suggest their use. This paper presents dynamic daylight simulation results related to an open-plan office, performed with Autodesk 3ds Max Design ® , which is a calculation software validated by recent researches…

Radio polarization maps of shell-type SNRs II. Sedov models with evolution of turbulent magnetic field

2017

Polarized radio emission has been mapped with great detail in several Galactic supernova remnants (SNRs), but has not yet been exploited to the extent it deserves. We have developed a method to model maps of the Stokes parameters for shell-like SNRs during their Sedov evolution phase. At first, 3-dimensional structure of a SNR has been computed, by modeling the distribution of the magnetohydrodynamic parameters and of the accelerated particles. The generation and dissipation of the turbulent component of magnetic field everywhere in SNR are also considered taking into account its interaction with accelerated particles. Then, in order to model the emission, we have used a generalization of t…

Present-day use of an empirical wave prediction method

2016

Knowledge of the offshore wave climate is key to the design of coastal engineering structures and to the study of shoreline evolution. To date, the available wave data have been limited both in time and space; even though there are several options for obtaining wave data calculated using complex numerical models at basin scale, design issues can in some cases be solved by means of simpler models. This paper shows whether, under certain conditions and in an enclosed basin, an old empirical model can provide results that are good enough to determine the design condition necessary for engineering purposes. The empirical model chosen to answer this question is called Sverdrup–Munk–Bretschneide…

The Fifteen Signs before Doomsday in Cotton Vespasian D. xiv: Role and Contextualisation

2010

Il saggio offre uno studio dettagliato, corredato di traduzione in inglese moderno, di un’omelia antico inglese sui Segni del Giudizio tramandata nel ms. London, British Library, Cotton Vespasian, D. XIV. Questa versione della leggenda dei Quindici segni antecedenti la fine del mondo è stata copiata nel codice probabilmente per assolvere a una funzione catechetico-didattica e mostra svariate analogie con trattati di natura numerologica e con testi pronostici conservati nello stesso manoscritto. Il contributo ha evidenziato come il testo dei Quindici segni e altre opere di natura profetica (come la Revelatio Esdra) condividano una serie di tratti peculiari, quali l’impiego di topoi numerolog…

Sleep disorders in menopause: Results from an Italian multicentric study

2016

Menopause in the female life cycle is a special period due to important hormonal, physical and psychological changes. Sleep disruption represents a common complaint for midlife and menopausal women, related to primary sleep disorders, including insomnia, sleep disordered breathing, restless legs syndrome (RLS), mood and anxiety disorder, other medical illness, hormonal-related vasomotor symptoms, and aging per se. Aims of our study were to evaluate the prevalence of sleep disorders in a sample of pre and post menopausal women, and to investigate the relationship between sleep and other medical disorders, and life habits. Among workers in the six participant centers, we enrolled 334 women, a…

From Togetherness to Equal Partnership in Role Play

1998

In the day care centre, already at the transition stage to role play children show different kinds of participation. They observe each other's play, share goal orientation and directly tutor each other. The play process is materially supported and often initiated by educators. However, children also need to acquire the power to act autonomously in role play. The different kinds of participation in young children's play, as well as the appearance and development of basic features of joint role play were examined in three games of a two‐year‐old girl, Katju, in her day care group. The games are examples of ten play sessions she was involved in. These data were collected by means of reactive p…
