Recensione a: NG Irene, The Pricing and Revenue Management of Services. A Strategic Approach, Routledge, UK
No full textIrene Ng’s book plays a significant role in the progress made in revenue management studies.
What the author actually does is not only to collect contributions from all the various previous works, but also she adds something completely new.
The text is split into two parts: the first looks at the question of pricing for service firms from the point of view of the customer: “the buyer as an individual”.
The second part of the book focuses on the issue of the “buyer as an aggregate”, i.e. “how do we go from one buyer to many buyers
Climate-related environmental stress in intertidal grazers: scaling-up biochemical responses to assemblage-level processes
No full textOrganisms are facing increasing levels of environmental stress under climate change that may severely affect the functioning of biological systems at different levels of organization. Growing evidence suggests that reduction in body size is a universal response of organisms to global warming. However, a clear understanding of whether extreme climate events will impose selection directly on phenotypic plastic responses and how these responses affect ecological interactions has remained elusive
L’efficienza del settore pubblico regionale attraverso gli indicatori di contesto e la spesa pubblica consolidata
No full textL’efficienza del settore pubblico regionale viene valutata mediante l’impiego di due tecniche non-parametriche, la FDH (Full Disposable Hull) e la DEA (Data Envelopment Analysis), che permettono di stimare l’efficienza di un’unità decisionale appartenente a un insieme omogeneo in base alla distanza fra le combinazioni input-output di quella unità e una frontiera costruita sulla base delle prassi migliori dell’insieme considerato. Nel caso specifico, quest’ultima è stata stimata a partire dalle variabili di contesto della banca dati QCS, utilizzati come misure di output, e della spesa pubblica consolidata, calcolati dal DPS, in qualità di input. Data l’ampiezza delle informazioni utilizzate, la costruzione degli indicatori ha richiesto preliminarmente la scelta di un metodo di normalizzazione e di un criterio di aggregazione. Nel far questo si è verificata anche la possibilità di utilizzare, in una veste nuova, i pesi forniti dall’applicazione della tecnica DEA. Alla luce dei punteggi-efficienza stimati troviamo che: (i) il numero di regioni efficienti cambia a seconda delle ipotesi riguardanti la forma della frontiera; (ii) le regioni efficienti sono prevalentemente quelle del Nord-Est e della fascia Centrale Adriatica (iii) sono presenti significative sacche di inefficienza.The efficiency of the regional public sector is evaluated according to two non-parametric techniques, the FDH and DEA, which estimate the efficiency of a given decision making unit as the distance between the observed input-output combinations and an efficient frontier based on the sample’s best practices. Our exercise utilizes as proxies for the level of outputs the context indicators drawn from the Community Support Framework databank, and as proxies for the level of inputs the consolidated public expenditure estimated by the Department for Development Policies, Ministry of Economy and Finance, Italy. Due to the large amount of variables involved, as a preliminary we select an appropriate normalization method and a suitable aggregation criterion. To this latter end, we also experiment with the weights resulting from the DEA application viewed as a method for achieving robust aggregation. The main findings are as follows: (i) the number of efficient regions changes according to the specific assumptions concerning the shape of the frontier; (ii) efficient regions are generally located in the North-East of Italy and along the Central Adriatic Coast, and finally (iii) there is considerable scope for improving efficienc

The Role of Blockchain in the Public Sector: An Overview
No full textIl capitolo esamina quale utilità e quali funzioni può avere la blockchain nel settore pubblico. Dopo aver espresso alcune riflessioni sulle obiezioni di fondo che si potrebbero muovere all'uso della blockchain nel settore pubblico, l'autore analizza alcuni degli elementi fondamentali della gestione dei dati, a partire dalla nozione di database. Avendo quindi descritto quali sono i processi funzionali per la gestione dei dati nel settore pubblico, l'autore illustra quali caratteristiche e funzionalità della blockchain potrebbero essere utili nel settore pubblico. Vengono quindi descritti alcuni potenziali utilizzi della tecnologia blockchain.The chapter examines what utility and what functions blockchain can have in the public sector. Having given some thoughts on the underlying objections that could be made to the use of blockchain in the public sector, the author analyses some of the fundamental elements of data management, starting from the notion of database. Having therefore described what are the functional processes for data management in the public sector, the author illustrates which features and functionality of the blockchain could be useful in the public sector. Some potential uses of blockchain technology are therefore described
Comparison of OXITEST and RANCIMAT methods to evaluate the oxidative stability in frying oils
No full textThe oxidation of fatty acids in the presence of
atmospheric oxygen is recognized as one of the main factors
affecting the shelf life of oils and fats causing rancidity
by the formation of off-flavors due to aliphatic aldehydes or
other volatile compounds. Therefore, the oxidative stability
is one of the most important parameters to be evaluated in
the formulation of commercial frying oils. In this regard, the
induction period of 15 frying oils has been measured using
two different methods of accelerated oxidation, OXITEST
and RANCIMAT, and correlated to their fatty acid content
previously detected by gas chromatographic technique.
Frying oils containing high contents of saturated fatty acids
mainly from the palm oil achieved an improved oxidative
stability by increasing their induction period. Moreover,
the linear regression analysis showed a good correlation
between the induction period values of the two instruments.
Hence, the innovative OXITEST method may be an easy,
fast, and eco-friendly alternative to the official RANCIMAT
method for evaluating the oxidative stability in oil- and fat containing
products
