MANAGEMENT CONTROL SYSTEMS FOR THE WATER CONCESSIONAIRES GOVERNANCE: A MULTIPLE CASES STUDY IN THE ITALIAN SEAPORTS
The purpose of this paper is to investigate the information and knowledge
management regarding the carried out processes into the seaport relationships
system in the Italian market. We focus on the relationships established between the
water concessionaires and Port Authorities (PAs), in order to examine the main
tools developed and adopted for facilitating their information and knowledge
sharing, recognizing their role in the performing of tasks assigned to the PAs by the
Law 84/1994. In the last decades, some reforms have significantly changed the port
facilities management because of the need to reduce costs and guarantee high
quality services. According to the main frameworks on the topic, we investigate
how management control, information systems and reporting tools can facilitate the
coordination and integration between water concessionaires and PAs in order to
support the long-term decision in the seaport, following a systemic viewpoint. This
qualitative work, adopting a multiple cases study methodology, compare four different
ports in the Italian seaport system (Civitavecchia, Naples, Trieste, and
Venice). Despite the crucial role played by the tools investigated in the information
sharing and coordination process, we observe still the lack of an integrative
information system—in terms of a shared digital platform—and, also, the presence
of strong resistances by both the players to deeply communicate and effectively and
efficiently interact to provide the water facility
Differenze contrattuali, comportamenti organizzativi e lavoro di gruppo: un'analisi empirica nel settore della riabilitazione
Molecular adaptation strategies to high temperature : D-trehalose/D-maltose-binding protein from the hyperthermophilic archaeon Thermococcus litoralis as an example
The D-trehalose/D-maltose-binding protein (TMBP), a monomeric protein of 48 kDa, is one component of the trehalose and maltose uptake system. In the hyperthermophilic archaeon T. litoralis this is mediated by a protein-dependent ATP-binding cassette system transporter.
The gene coding for a thermostable TMBP from the archaeon T. litoralis has been cloned, and the recombinant protein has been expressed in E. coli. The recombinant TMBP has been purified to homogeneity and characterized. It exhibits the same functional and structural properties as the native one. In fact, it is highly thermostable and binds both trehalose and maltose with high affinity.
In this work we used differential scanning calorimetry (DSC) studies together with a detailed analysis, at the molecular level, of the three-dimensional protein structure to shed light on the basis of the high thermostability exhibited by the recombinant TMBP from the archaeon T. litoralis.
The obtained data suggest that the presence of trehalose does not change the overall mechanism of the denaturation of this protein, but it selectively modifies the stability of the TMBP structural domains.

REGULATION IN THE SPORTS SETTING: TRAINING PROGRAMS TO REDUCE UNETHICAL BEHAVIORS
There has been increasing recognition of the need for regulations effectiveness, in terms of understanding
and compliance with the rules, in the sport settings. This is important because sport is a rule-governed
practice: constitutive rules, both prescriptive and proscriptive formal rules of play, define required equipment
and facilities; auxiliary rules specify and control eligibility; regulatory rules place restraints on behaviour
independent of the sport itself. This paper provides a review of regulations in sport settings and it focuses on
managerial implications, in terms of training programs on dynamical process for ethical and unethical
behaviors in systems significantly based on rules: for a qualitative exploratory study, we assume that
understanding and being aware of the rules from the point of view of their technical contents is a necessary
but not sufficient condition for the rule to be applied and ethically applied. Training on the intentional
violations of the rules decided by the principal administrators of the system and the dynamical process which
let to automatic adjustment to infringements frequently implemented by other stakeholders could prevent or
reduce the corruptive phenomenon and increase rules effective application in sport settings
The revenues of local governments in the statistical register for public administrations: inequality decomposition by sources
During the last decade, the Italian national institute of statistics (Istat) has been
engaged in a modernization program involving the revision of the statistical
production model. The main goal behind this program is the use of statistical
registers integrated into a single logical environment, the Italian Integrated System
of Statistical Registers (ISSR), for supporting the consistency of statistical
production processes and improving the quality of information for users. One object
of the ISSR is the satellite statistical REgister for Public Administrations (REPA)
that contains information on structural and economic variables on a subset of the
Italian PA. The public institutions are different from each other in structures, dimensions,
and scopes. In the present paper, these differences are analysed by looking at their
revenues. For this aim, the inequality in the revenues, measured with the Gini index,
is decomposed “by sources”
MEASUREMENT AND CONTROL CHALLENGES IN THE HUMAN CAPITAL MANAGEMENT FOR MENTORING RELATIONSHIPS SYSTEM
The aim of this paper is to identify and describe possible measurement
indicators for monitoring the performance within a mentoring relationships system.
We propose to investigate which factors can provide an adequate assessment of
mentoring recognized as one innovative and specific technique to support the
human resources management policies within any organizations. We analyze
mentoring programs applied in different organizational settings evidencing their
main functions and application areas and trying to evidence if and how some
specific factors can affect their effectiveness. Starting from these dimensions, we
develop and analyze key performance indicators which can support the mentoring
evaluation process. This is a theoretical study that, through a review of the literature
on mentoring topic, allows us to identify and evidence a set of effective and
successful key performance indicators. This study outlines some relevant key
factors for generating and developing effective mentoring programs by systematizing
and clarifying the main contributions on this topic and identifying new
research perspectives
Port Community System e Smart Port per il miglioramento della performance: il caso del sistema portuale di Amburgo
Il sistema portuale e la complessiva sea-land supply chain rappresentano un campo interessante per studiare gli effetti derivanti dall’adozione di tecnologie digitali per la gestione efficace ed efficiente dei processi operativi ed organizzativi nella loro complessità. Negli ultimi trenta anni, i porti hanno dovuto affrontare numerose sfide ascrivibili alla ratifica di convenzioni internazionali e al recepimento delle direttive europee soprattutto in materia di gestione dei flussi informativi dei sistemi portuali, in particolare al loro grado di digitalizzazione. D’altra parte, i sistemi portuali sono chiamati a gestire anche le criticità connesse ai mutamenti del commercio internazionale, all’introduzione di navi di grandi dimensioni, ai cambiamenti nella domanda di servizi e allo sviluppo delle tecnologie sia a bordo delle navi, sia nelle infrastrutture portuali fino così ad assumere una posizione strategica come “hub port” (Keceli et al., 2008). In particolare, con riguardo alle innovazioni strettamente connesse alla navigazione marittima, nell’ultimo decennio, l’Unione Europea (UE) ha promosso e-maritime, cioè un’iniziativa focalizzata sull’Information Communication Technology (ICT) per migliorare la competitività, la sicurezza e la sostenibilità in materia di navigazione marittima (Pipitsoulis, 2009). Questa iniziativa, derivata dal concetto di e-navigation introdotto dall’International Maritime Organization (IMO), si pone l’obiettivo di promuovere e suggerire modelli efficienti e semplificati grazie al supporto delle tecnologie digitali per favorire la cooperazione e l’interconnettività tra tutti gli attori della filiera marittima. Dunque, l’obiettivo dell’iniziativa e-maritime e della strategia di e-navigation dell’IMO è di raccogliere, integrare, scambiare e analizzare le informazioni marittime a bordo delle navi e in mare aperto (IMO, 2005). Nonostante il settore marittimo continui a registrare una crescente e considerevole adozione di tecnologie digitali sia a bordo delle navi, sia a terra, gli studi su questo tema appaiono ancora frammentari (Joszczuk-Januszewska, 2012, 2013, 2014). Solo recentemente lo studio e lo sviluppo di sistemi informativi per migliorare l’efficienza, la sicurezza e la sostenibilità dell’intero settore marittimo sta accogliendo un crescente interesse da parte della comunità scientifica. In questa direzione, il presente studio mira ad investigare le principali implicazioni nella gestione delle informazioni tra più player dovute a scelte di digitalizzazione dei processi organizzativi e operativi. In particolare, l’attenzione è posta sulle possibili relazioni fra l’adozione di “digital platform”, “accounting information system” e “sustainable performance” nei sistemi portuali. Questo studio dopo aver verificato l’adozione di “smart technologies” quali Industrial Internet of Things (IoT), Industrial Analytics e Cloud Manufacturing (Information Technology – IT) e Advanced Automation, Advanced Human Machine Interface e Additive Manufacturing (Operational Technologies - OT) in uno dei principali sistemi portuali in Europa, quale è Amburgo, si sofferma sul ruolo assunto dalle piattaforme digitali come il “port communty system” (PCS) nei processi organizzativi e operativi e nelle possibili interconnessioni con l’Accounting Information System (AIS) e Management Control System (MCS). Il presente capitolo fornisce un’analisi di queste principali modalità esecutive attraverso le quali l’IT può migliorare le operazioni portuali e i processi globali. Questo capitolo, infatti, fornisce una breve review della regolamentazione a livello internazionale, europeo e nazionale e della letteratura sul tema delle tecnologie smart applicate ai porti portando alla definizione dei c.d. smart port nell’ottica di migliorare la loro performance anche realizzando propriamente una performance sostenibile. Si focalizza l’attenzione su una specifica piattaforma digitale centralizzata per la gestione dei flussi di traffico nella comunità portuale, quale il PCS. Tale piattaforma digitale è investigata anche illustrando la sua funzione e ruolo nell’utilizzo combinato con gli strumenti di Accounting Information System (AIS) e Management Control System (MCS). Il capitolo, inoltre, si conclude con una interessante analisi di un caso rappresentativo di smart port, ossia il sistema portuale di Amburgo
Combining Multiple Imputation and Hidden Markov Modeling to Obtain Consistent Estimates of Employment Status
Recently, a method was proposed that combines multiple imputation and latent class analysis (MILC) to correct for misclassification in combined data sets. A multiply imputed data set is generated which can be used to estimate different statistics of interest in a straightforward manner and can ensure that uncertainty due to misclassification is incorporated in the estimate of the total variance. In this article, MILC is extended by using hidden Markov modeling so that it can handle longitudinal data and correspondingly create multiple imputations for multiple time points. Recently, many researchers have investigated the use of hidden Markov modeling to estimate employment status rates using a combined data set consisting of data originating from the Labor Force Survey (LFS) and register data; this combined data set is used for the setup of the simulation study performed in this article. Furthermore, the proposed method is applied to an Italian combined LFS-register data set. We demonstrate how the MILC method can be extended to create imputations of scores for multiple time points and thereby show how the method can be adapted to practical situations
