SuntoL’autore illustra le varie modalità con cui viene posta in essere la multiproprietà (o godimento turnario) nel nostro ordinamento. Inoltre, visto il sempre più frequente uso di modelli di common law, vengono illustrate anche le principali modalità con cui viene gestito il time-share in detti ordinamenti: il club e il trust. In tal modo, viene offerta una panoramica esaustiva delle soluzioni adottate e adottabili dai professionisti italiani nelle operazioni relative a multiproprietà.

Full textAbstract:
Il turismo č un fenomeno fortemente localizzato. Le caratteristiche del territorio ne denotano strutturalmente il profilo e i molteplici modelli di offerta cercano di soddisfare la variabilitŕ dei gusti e delle esigenze dei visitatori. Sulla base della rilevazione ISTAT sul movimento nelle strutture ricettive, che fornisce informazioni in serie storica sul turismo interno italiano al livello di provincia, viene proposta un'analisi descrittiva, in chiave territoriale, della dinamica delle presenze (pernottamenti) per il periodo 1997-2007. L'obiettivo di fondo consiste nell'analizzare tre aspetti, correlati ma distinti: 1) la presenza di tendenze di medio- lungo periodo differenziate a livello territoriale; 2) la rilevanza statistica della dimensione territoriale, rispetto ad altri potenziali fattori esplicativi, come particolarmente discriminante di tendenze evolutive diverse; 3) la misurazione dell'eterogeneitŕ delle dinamiche provinciali non osservabile sulla base dei soli indicatori medi aggregati.

Full textAbstract:
Il rapporto tra le dimensioni fondamentali del vivere sociale e le caratteristiche dei ‘nuovi' turisti sono molto strette, a dimostrazione del ruolo rilevante assunto dal fenomeno turistico; la dimensione globale, lo spazio estetico, la ridefinizione delle coordinate spazio-temporali, il desiderio di recuperare relazioni interpersonali significative determinano in modo decisivo le scelte turistiche. L'autore si sofferma sulla crescente attenzione per la natura e per la ruralitŕ, che conduce alla diffusione di nuove forme di fruizione del territorio, come le greenways, e di modelli innovativi di ricettivitŕ come gli agriturismi. Lo stretto legame che si instaura tra turismo e ambito rurale si esprime in particolare nella riscoperta delle culture e delle tradizioni dei luoghi d'origine dei prodotti enogastronomici. Il binomio turismo-agricoltura č rafforzato dal fatto che la ristorazione e le ricette locali sono parte integrante di ogni tipologia di prodotto turistico. Anche alcune aree montane in difficoltŕ possono trovare occasioni di rinascita sociale ed economica sviluppando il turismo enogastronomico. La rete locale dei soggetti che agisce sul territorio per sviluppare una tale offerta turistica deve peraltro essere suggellata da una progettualitŕ condivisa, che coinvolga la popolazione locale e si ispiri a modelli di sostenibilitŕ: una delle componenti fondamentali del sistema turistico č costituita dalla partnership strategica tra i partecipanti, che li accomuna attorno a progetti di sviluppo.

Nel mondo digitale contemporaneo lo skills mismatch e la mancanza di opportunità di lavoro per i giovani rappresentano sfide non agevoli da affrontare. Per far fronte a tali difficoltà si ritiene che l'apprendistato possa giocare un ruolo chiave, in grado di consentire ai giovani di acquisire le competenze necessarie a facilitare la loro transizione dall'educazione al lavoro. La pedagogia è pertanto chiamata a riflettere sulla possibilità di pensare a modelli di apprendimento integrati, in grado di stabilire connessioni tra istruzione/formazione e lavoro con modalità nuove. Tra i criteri per apprendistati efficaci e di qualità appare centrale il supporto pedagogico, offerto da personale interno alle imprese, con l'incarico di collaborare strettamente con le istituzioni formali. Sebbene l'importanza del mentoring nell'apprendistato sia ampiamente riconosciuta, la ricerca non ha sempre prestato adeguata attenzione alle competenze educative che i mentori dovrebbero possedere per preparare gli studenti quali learning agent. Lo studio qui presentato intende fornire un contributo di ricerca, definendo un modello di formazione per mentori. Il saggio - che descrive il progetto di ricerca internazionale ApprEnt - presenta il prototipo elaborato per la formazione di mentori competenti.

Full textAbstract:
È sempre più diffusa la richiesta di cura avanzata da coppie, siano esse coniugali, di fatto o ricostituite. Ciò è dovuto anche alla trasformazione dello scenario culturale relativamente al rapporto tra relazione di coppia e relazione familiare. La clinica di coppia è così diventata un vero e proprio genere terapeutico con sue specificità, in cui il cliente è la relazione tra i partner e il destino di tale relazione. Il contributo focalizza poi l'attenzione sulle differenti concezioni epistemologiche ed etiche che guidano il lavoro clinico con la coppia. La prima concezione, quella supportata empiricamente (Empirically Supported Treatments), propone un'etica basata sull'efficacia-utilità della cura; la seconda, quella supportata qualitativamente, si fonda su un'etica relazionalmente orientata e tende verso la ricerca di senso sia in merito alla relazione di coppia sia alla relazione coppia-terapeuta. Affronta poi, entro tale cornice, la questione della differenza, cruciale nel fare ricerca sulla psicoterapia, tra teoria e modello per un verso e tra metodo e tecniche per l'altro. Evidenzia infine come sia possibile un reale ed efficace incontro tra pratica clinica e ricerca empirica a proposito della relazione di coppia aldilà delle differenze tra modelli terapeutici. A tale proposito vengono offerte indicazioni metodologiche in grado di tener conto sia della variabile personale (i partner, ma anche il terapeuta), sia del legame in quanto tale (la relazione di coppia, ma anche la relazione terapeutica).

A fronte delle potenzialitŕ offerte dai continui sviluppi tecnologici, il problema principale non č oggi l'indisponibilitŕ di ausili, ma la possibilitŕ di individuare quali siano le tecnologie giuste per una soluzione personalizzata nel singolo caso, come acquisirle, assemblarle, come imparare ad usarle efficacemente. Nel presente contributo analizzeremo il modo in cui i modelli tradizionali di "assistenza protesica" possono evolvere verso modelli piů moderni di "accompagnamento" dell'utente nella scelta delle tecnologie, nei quali l'informazione sulle tecnologie disponibili e l'educazione dell'utente all'autonomia giocano un ruolo sostanziale. Questi concetti verranno esemplificati con casi di studio e strumenti innovativi tratti dall'esperienza del Polo Tecnologico e del Servizio DAT (Domotica Ausili Terapia Occupazionale) della Fondazione Don Gnocchi di Milano.

Abstract In his creation of this narrative of friendship featuring the divitis filius and pauperis filius, the declaimer was clearly influenced by cultural and anthropological exemplars of undisputed validity. They range from Seneca's philosophical paradigm of the sapiens to the military vir fortis and the prototype of the certus amicus. Oxymoronic stans periit specifically characterizes the poor man's son's aloofness from the ill-fame attached to gladiators. It also marks his death in battle: scorning the exit offered by the gladiatorial lex pugnandi, he chooses the law for bellica certamina, which offers the only opportunity to display virtus.

IntroduzioneÈ stato convincentemente sostenuto che, una volta consolidati, alcuni sistemi partitici sono in grado di modificare, talvolta con effetti destabilizzanti, i modelli della competizione politica. Questi non dipendono dunque soltanto dai fenomeni di alienazione, dalle ideologie o dal mutamento delle issues presenti nella società, ma sono anche il risultato degli incentivi e delle opportunità offerti ai partiti e agli elettori dalle condizioni create dallo stesso sistema partitico. La teoria del pluralismo polarizzato di Giovanni Sartori è senz'altro l'analisi piò sofisticata e piò ampiamente citata al proposito.

In primo luogo, esso ricostruisce il nesso fra i tre elementi e individua le principali critiche ecologiche alla democrazia ambientale. Quindi considera i due modelli di partecipazione ambientale ("ottativa" e "prescrittiva") offerti dalla comparazione, nel quadro della triplice emergenza contemporanea (ecosistemica, climatica e fossile), diversa dalle già conosciute emergenze ambientali. Infine, considera le prassi di litigation strategy ed "eco-democrazia" in quanto reazioni a queste emergenze, nella contestuale individuazio-ne del "mandato climatico" quale nuova prescrizione deliberativa di "protezione sostenibile".

Full textAbstract:
Retail business models, both with respect to overall retail operations, as well as individual types of retail organisations, are undergoing transformation brought on by the current economic environment. This can be attributed to growing competition, changes to customer behaviour and expectations, globalisation, as well as the availability and development of new information technologies. This paper outlines the essence and fundamental components of retail business models, indicates the probable directions in which those models may evolve and identifies the determining factors and trends that shape the business models applied by retailers. In her analysis the author has demonstrated that although the retail sector eagerly embraces innovation, any changes to business models are evolutionary in their nature. They mainly involve the introduction of new solutions in terms of store formats, cooperation within the distribution channels, changes to the range of products and services offered and the use of mobile technologies.

Full textAbstract:
2006/2007Nel corso del presente lavoro di tesi è stata presentata un’analisi delle problematiche inerenti alla schematizzazione dell’offerta di trasporto alla scala regionale, evidenziando i vantaggi derivanti da un utilizzo congiunto di modelli di simulazione e sistemi informativi. L’attività di ricerca è stata condotta nell’ambito di un accordo di collaborazione scientifica tra il Dipartimento di Costruzioni e trasporti dell’Università di Padova e la Provincia di Venezia, sul tema della progettazione ed implementazione di un sistema informativo a supporto della pianificazione e del monitoraggio del sistema dei trasporti delle persone, relativamente ad un ambito territoriale extraurbano quale quello provinciale. In particolare l’analisi ha interessato la componente relativa alla rappresentazione dell’offerta di trasporto, sia per quanto riguarda la schematizzazione topologica della rete di trasporto e la zonizzazione del territorio che per quanto concerne la valutazione prestazionale della rete mediante funzioni di costo. La realizzazione di tale sistema informativo secondo metodologie evolute proprie di ambiti disciplinari trasversali all’Ingegneria dei trasporti (sistemi informativi territoriali) è stata quindi avvalorata da un’analisi delle esigenze da considerare nel processo di schematizzazione ai fini dell’analisi trasportistica. Infatti partendo da una rete commerciale gerarchica (RC), che costituisce una fonte di dati disponibile e aggiornata periodicamente ed operando coerentemente con gli standard normativi attuali (TRANSMODEL e GDF), sono state individuate e materializzate le corrispondenze tra questa ed il grafo della rete viaria (GRV), sviluppando allo scopo specifiche procedure informatiche. Una volta realizzata la corrispondenza fra gli elementi del GRV e quelli della RC, si sono potute sfruttare in modo efficiente, ai fini dell’analisi trasportistica, le potenzialità di uno strumento quale il sistema di gestione della base di dati nella fornitura, organizzazione ed estrazione di informazioni dai dati. Non si è tralasciato inoltre di indagare e testare le possibilità di una gestione organica ed unitaria delle varie schematizzazioni ed elaborazioni relative ad uno stesso contesto territoriale (ad esempio grafo del trasporto privato e grafo del trasporto pubblico). L’analisi delle funzioni di prestazione da associare agli archi del grafo è partita da una ricognizione delle formulazioni presenti in letteratura (e dal confronto metodi e valori proposti dall’HCM). Tale analisi ha permesso di constatare come le formulazioni utilizzate provengano da approcci in buona parte empirico-induttivi, privi di una modellizzazione del fenomeno basata su di un procedimento rigorosamente deduttivo. Le ragioni di tale lacuna sono molteplici. Innanzitutto la teoria del deflusso non presenta, in generale, i livelli di accuratezza descrittiva riscontrabili in altri campi (fisica meccanica, termodinamica ecc.). Ciò è dovuto alla presenza di caratteristiche di eterogeneità ed aleatorietà difficilmente eliminabili, soprattutto nel caso di rappresentazioni aggregate. Soprattutto in contesti come quelli dell’Area Centrale Veneta, caratterizzata da un’urbanizzazione diffusa, la frammentarietà delle caratteristiche della viabilità secondaria rendono problematica la descrizione del fenomeno sulla base di poche grandezze, relativamente alle quali si possa ipotizzare di disporre informazioni per tutti gli elementi della rete. Infatti in una visione a livello macroscopico del deflusso veicolare tali caratteristiche di eterogeneità (interna alle grandezze utilizzate come variabili esplicative) si traducono in componenti significative di varianza non spiegata. D’altra parte l’assunzione di un tale punto di vista risulta necessaria nell’analisi del sistema di trasporto nel suo complesso, in particolar modo nel caso della modellizzazione a scala regionale. Inoltre si deve considerare che le funzioni di costo, oltre a rappresentare in maniera realistica le prestazioni dell’arco al variare del flusso, devono rispondere alle esigenze poste dal loro utilizzo negli algoritmi di assegnazione. Occorre poi tener presente che il livello di tolleranza, spesso piuttosto ampio, è legato a quello più generale accettato nel processo di determinazione dei flussi e dei percorsi scelti dagli utenti nella rete. Da un punto di vista pragmatico appare pertanto, in molti casi, sostanzialmente inutile oltre che gravoso e non sostenibile in termini di requisiti informativi spingere l’analisi verso modellizzazioni particolarmente raffinate ed articolate. Pertanto, nell’ambito del processo di modellizzazione, la mancanza di una caratterizzazione ed interpretazione, unitamente all’esigenza di una rappresentazione semplificata, aumenta l’importanza relativa delle fasi di calibrazione e attribuzione agli archi delle funzioni di costo. É stata quindi elaborata una metodologia di classificazione funzionale degli archi della rete sulla base delle informazioni provenienti dalla banca dati Multinet in modo da rendere maggiormente efficiente la fase di calibrazione delle funzioni di costo. Va osservato come la classificazione sia stata effettuata su un numero limitato di informazioni. L’integrazione con altre fonti dati (come il Catasto Stradale), nel caso del presente studio non disponibili, e/o un arricchimento del contenuto informativo nelle prossime versioni della banca dati potranno portare ad un notevole miglioramento dell’efficacia del metodo. Nell’ambito dello studio è stata effettuata la calibrazione di funzioni di costo, segnatamente del tipo “BPR”, per alcuni archi campione delle classi di archi definite. Allo scopo sono stati realizzati diversi rilievi sia su sezione che su tratta: la metodologia di rilievo su sezione, pur consentendo un facile approvvigionamento dei dati, pone il problema della rappresentatività del dato rilevato su sezione, allorquando lo si riferisca ad un intero arco della rete. Per ovviare a tali inconvenienti si è quindi proceduto alla realizzazione di rilievi su tratta; tuttavia tali rilievi hanno comportato diverse difficoltà operative ed interpretative. Pertanto, date le problematiche insite nei vari metodi, si ritiene auspicabile l’utilizzo di un approccio integrato, includendo il metodo del veicolo sonda, che, oggigiorno, si può avvalere delle possibilità offerte dalla tecnologia GPS. Sviluppi futuri della ricerca potranno consentire di espandere il campione di calibrazione ed estendere l’analisi ad altre forme funzionali. Ulteriori spunti di approfondimento riguardano l’analisi delle condizioni di stazionarietà, relativamente agli intervalli temporali di riferimento e l’influenza di diverse tipologie di veicoli e dei flussi in archi diversi da quello considerato (funzioni non separabili) sulle modalità del deflusso. In tal senso risulterà particolarmente efficace l’impiego delle funzionalità del sistema informativo proposto nel porre in relazione i diversi elementi di interesse.

Over the last 20 years, electricity markets around the world have gradually been deregulated, creating wholesale markets in which generating companies compete for the right to supply electricity, through an offering system. This thesis considers the optimisation of the offering process from the perspective of an individual generator, subject to intertemporal constraints including fuel limitations, correlated rest-of-market behaviour patterns and unit operational decisions. Contributions from the thesis include a Pre-Processing scheme that results in considerable computational benefits for a two-level Dynamic Programming method, in addition to the development of a new process that combines the techniques of Decision Analysis and Dynamic Programming.

Janawade, Vikrant. "Evaluation par le consommateur des services offerts par des réseaux de firmes : valeur perçue, satisfaction et comportement dans le contexte des alliances aériennes." Thesis, Aix-Marseille, 2014. http://www.theses.fr/2014AIXM2010.
Full textAbstract:
Cette thèse explore la perception par les consommateurs de services offerts par des firmes organisées en réseau. De nos jours, les clients sont confrontés de plus en plus à des situations de service complexes bien différentes des situations simples analysées traditionnellement par le marketing et le management des services (un seul service délivré par une entreprise bien identifiée et choisie par le client). Les entreprises de services ont évolué vers des offres de plus en plus complexes et riches (« fleurs de services », « bouquets » ou « constellations ») dans lesquelles le client se voit proposer des offres intégrant plusieurs prestataires, parfois mal identifiables. Le choix du client gagne en simplicité mais perd en liberté et l'on sait peu de choses sur les conséquences que cela peut avoir sur son comportement ultérieur. L'hypothèse centrale est qu'à la suite d'une expérience de ce type de service, le client opère une synthèse en termes de valeur perçue du réseau, et que cela détermine largement son comportement ultérieur. Une enquête par questionnaire menée dans le contexte des alliances aériennes, confirme que cette hypothèse peut être acceptée. Les alliances globales formées par les compagnies aériennes constituent un terrain d'observation privilégié car les services sont offerts aux clients à la fois par des compagnies de transport indépendantes et par une organisation commune assurant la coopération et la coordination nécessaires. Le modèle d'équations structurelles estimé par PLS-SEM identifie en outre les déterminants de la valeur perçue d'une alliance dans le cadre de transports aériens de longue durée et permet de hiérarchiser leurs impacts respectifsThis research explores the services offered by networked firms and the way in which they are perceived by the customers. Nowadays customers are facing more and more often complex service situations which drastically differ from the simple situations traditionally analysed by service marketing and management studies (a single service delivered by a well identified single firm deliberately chosen by the consumer). Service firms now propose more and more complex and enriched offerings (service "flowers", "bunches" or "constellations") grouping several providers, but among them some are hardly identifiable by the customer. Consumers' decision is made simpler but a part of their liberty of choice has been lost. Little is known about the consequences this can have on their future behaviour.The main hypothesis is that after experiencing a service delivered by networked firms, the consumers synthesize all their perceptions in terms of the perceived value of the network; furthermore, this assessment will largely determine their behavioural intentions. A quantitative survey shows that such a hypothesis can be accepted. This survey was conducted in the field of airline industry, aiming at multi-lateral airline alliances. This context is particularly appropriate to our subject because during such a travel, services are delivered to passengers by independent airline companies as well as by the common organisation in charge of the co-ordination and co-operation. The structural equations model tested using the PLS-SEM method also identifies the determinants of perceived value of an alliance in the specific context of long haul flights and their respective weights and contributions

This study aimed to verify whether it is possible to estimate an econometric model to predict the behavior of issuers of new shares of Fundos de Investimentos em Participações (FIPs) based on some explanatory variables for the most part, based on macroeconomic variables in the model estimated in the study of Iaquipaza (2005). We analyzed a series of 75 observations, on the number of FIPs’ offers made each month, from October 2003 to December 2009. To analyze the time series of FIPs’ offers, was used a model of Poisson regression, to work with the count data that made up the dependent variable sample. The results showed the influence of some variables listed in study Iaquipaza (2005) and others that were included in the model due to the specific type of asset analyzed. However, the study is limited by the fact that it was studied an industry still in its beginning, which culminated in the estimation of a model with few observations.
Este trabalho objetivou verificar se é possível estimar um modelo econométrico para prever o comportamento dos emissores de novas cotas de Fundos de Investimentos em Participações (FIPs) com base em algumas variáveis explicativas, em sua grande maioria, variáveis macroeconômicas baseadas no modelo estimado no trabalho de Iaquipaza (2005). Foi analisada uma série histórica de 75 observações, referentes ao número de ofertas públicas de FIPs realizadas em cada mês, no período de outubro de 2003 a dezembro de 2009. Para analisar a série histórica de ofertas públicas de FIPs utilizou-se um modelo de regressão de Poisson, para trabalhar com os dados 'contáveis' que compunham a amostra da variável dependente. Os resultados indicaram a influência de algumas variáveis indicadas no trabalho de Iaquipaza (2005) e de outras que foram incluídas no modelo em virtude da especificidade do tipo de ativo analisado. Contudo, o trabalho tem como limitação o fato de ter sido estudada uma indústria ainda incipiente, o que culminou na estimação de um modelo com a utilização de poucas observações.

Este modelo, que é uma generalização do modelo de múltiplos estados proposto pelo Continuous Mortality Investigation Bureau no seu relatório n°12, em 1991 (CMIR 12[1991]), é um modelo que se torna útil nas etapas de subscrição de seguros e de gestão de indemnizações IP.Nos capítulos 1 e 2 desta tese estudamos detalhadamente o modelo proposto em CMIR 12[1991] e o modelo mais geral proposto em Cordeiro [2002a], respectivamente. Para cada um destes modelos apresentamos: a sua base matemática, as fórmulas das probabilidades básicas que se podem definir a partir do modelo, os algoritmos numéricos que permitem obter de uma forma eficiente valores de algumas das probabilidades básicas e as regularizações das intensidades de transição do modelo. No capítulo 3 utilizamos o modelo mais geral para calcular os prémios puros, quer de apólices IP que oferecem coberturas totais, quer de apólices que oferecem coberturas parciais, ou seja, que incluem nas suas coberturas apenas algumas classes de causas de incapacidade. Para o efeito, utilizamos os algoritmos numéricos para o cálculo das probabilidades básicas e as regularizações das intensidades de transição apresentados no capítulo 2. No capítulo 3 fazemos ainda a análise dos resultados obtidos.
Cordeiro [2002a] presented a new multiple state model which enables us to analyse Income Protection (IP) claims by cause of disability. This model, which is a generalization of the multiple state model presented by the Continuous Mortality Investigation Bureau in its 12th report, in 1991 (CMIR 12(1991]), is a very useful tool in the underwriting and claim control stages of IP business. In chapters 1 and 2 of this thesis we study in detail the model proposed in CMIR 12(1991] and the more general model proposed in Cordeiro [2002a], respectively. For each of these models we present: the mathematical basis of the model, formulae for the basic probabilities which can be defined with the model, the numerical algorithms which enable us to evaluate efficiently some of the basic probabilities and the graduations of the transition intensities of the model. In chapter 3 we use the more general model to calculate net premiums both for IP policies which offer total protection and for policies which offer partial protection (i.e. which cover only some classes of causes of disability. For that purpose, we use the numerical algorithms which allow us to calculate the basic probabilities efficiently and the graduations of the transition intensities presented in chapter 2. In chapter 3 we also analyse the results obtained.

AbstractIn this chapter, we examine the association between forgiveness and flourishing. We begin by identifying what forgiveness and flourishing are. We then move to considering conceptual models as well as evidence supporting the connection between forgiveness and flourishing. An early model of the forgiveness and mental health relationship offers a beginning in this regard. Next, we examine the stress-and-coping models of forgiveness of oneself and others. The final model is the scaffolding self and social systems model of forgiveness and subjective well-being. These models offer multiple vantage points from which to consider the forgiveness-flourishing connection. Limitations to these models and to the current state of knowledge on forgiveness and flourishing are highlighted, especially the limits to comprehensive assessment of flourishing in the extant literature. Conclusions and future directions for studying and promoting flourishing in people of different religious affiliation, cultures, countries, and life-circumstances are discussed in closing.

AbstractAdvanced systems engineering (ASE) is a new paradigm for agile, efficient, evolutionary, and quality-aware development of complex cyber-physical systems using modern digital technologies and tools. ASE is essentially enabled by smart digital modeling tools for specifying, modeling, testing, simulating, and analyzing the system under development embedded in a coherent and consistent methodology.The German Federal Ministry of Education and Research (BMBF) projects SPES2020, SPES_XT, and CrESt offer such a methodology and framework for model-based systems engineering (MBSE). The framework provides a comprehensive methodology for MBSE that is independent of tools and modeling languages. The framework also offers a comprehensive set of concrete modeling techniques and activities that build on a formal, mathematical foundation. The SPES framework is based on four principles that are of paramount importance: (1) Functional as well as non-functional requirements fully modeled and understood at system level. (2) Consistent consideration of interfaces at each system level. (3) Decomposition of systems into subsystems and their interfaces. (4) Models for a variety of cross-sectional topics (e.g., variability, safety, dynamics).

AbstractStructural runtime models provide a snapshot of the constituents of a system and their state. Capturing the history of runtime models, i.e., previous snapshots, has been shown to be useful for a number of aims. Handling, however, history at runtime poses important challenges to tool support. We present the InTempo tool which is based on the Eclipse Modeling Framework and encodes runtime models as graphs. Key features of InTempo, such as, the integration of temporal requirements into graph queries, the in-memory storage of the model, and a systematic method to contain the model’s memory consumption, intend to address issues which seemingly place limitations on the available tool support. InTempo offers two operation modes which support both runtime and postmortem application scenarios.

AbstractEvery day more midwives and other healthcare practitioners (HCPs) realise that good care has to consider their clients’ sexual well-being. Still, many find it challenging to breach the topic during a consultation by talking to their clients about sexuality. This chapter explores the thresholds midwives and other healthcare practitioners experience when it comes down to talking about sex with their clients. Drawing on existing models of health and well-being, such as the biopsychosocial model of health, and existing models for communication in clinical settings, such as the ICE model, the chapter offers a simple and easy to use four-step communication model—starting with raising the issue of sexuality pro-actively and ending by making the client an offer. This approach can help healthcare practitioners to integrate sexuality into their daily practice.“Talking sexuality” is a part of the more extensive publication “Sexuality & Midwifery”, an open access textbook published by Springer Nature, geared at midwives and related healthcare professionals, providing an overview of the current scientific knowledge on sexuality and midwifery, presented in a practice-oriented way.

Full textAbstract:
The practitioners of activities such as bouldering or mountain climbing sometimes find themselves in the situation of needing textile equipment that offer protection without limiting the body mobility. Modern design implies a complex process, from concept, to modelling, to prototyping and testing. The paper presents a tutorial which is useful for training of all those involved in designing, modelling and manufacturing knee pads integrated into protective garments, using certain principles regarding ergonomics, impact force management, texture, weight etc. The use of modelling software such as Rhinoceros 3D and Grasshopper offer also a wide array of tools for creating a virtual model which be later evaluated in virtual strain tests. The next step is creating a physical prototype, in order to test and compare materials, textures and physical parameters. This is where 3D printing technologies come in, compacting the physical modelling and prototyping process and offering designers, manufacturers or students a better control over the whole design and development process. Parameters such as material, infill, shell thickness can greatly influence an object's behaviour under strain tests. The fact that it can be build a minutely accurate scale prototype of a model in a very short time, without having to deal with the logistic or acquisition of expensive precision equipment, is especially relevant in the current context of the pandemic. This offers the possibility to create several prototypes of knee pads, made from plastics of varying degrees of rigidity, with differing infill percentage and layout, which will be further tested in order to assess their fit with the needs of climbers. In this context, 3D printing offers a new perspective in prototyping, providing a compact solution for most of the challenges in developing new functional or protective textile products.

Full textAbstract:
Bayesian networks offer an intuitive method of modelling causal relationships between the triggering events that lead to equipment impact on a pipeline. This method offers an advantage over the more well-known fault-tree methods due to its ability to use Bayesian inference for updating the prior probabilities of triggering events that lead to equipment impact such as, failure of permanent markers, use of one-call system, or failure of right-of-way patrol. In this paper, a modelling approach for a Bayesian network for equipment impact assessment, based on the available fault-tree method, is demonstrated. The advantages of the Bayesian network, such as updating the occurrence rates of basic triggering events and tracking information flow based on partial and incomplete information are illustrated by using the event data available from the damage incident reporting tool (DIRT) of Common Ground Alliance (CGA).

Full textAbstract:
Abstract One of the major challenges the oil and gas industry faces is the enablement of fast and seamless multi-disciplinary integration across the reservoir, production, network and facilities. Integrated Asset Management (IAM) is a key concept for making critical decisions about assets development and to maximise asset value. Although the IAM concept has been used in the past, it's tough to implement due to its inherent complexities. This paper introduces the latest technical innovations and processes that make IAM approach practical and reliable for its implementation. This innovative solution offers flexibility to rapidly adjust the model through "automatic and fast model updates" and provides a fit-for-purpose integrated model. The solution improves the speed and accuracy of decisions, and assists in field development planning workflows, modelling operational challenges and addressing debottlenecking options while considering all the domain constraints and development scenarios. Integrated asset modelling methodology used in this paper, is flexible in capturing domain science at different fidelity levels, incorporating fit for purpose physics, ranging from analytical models to highly complex reservoir simulation models with high-resolution grids that capture geological complexity. Operational logic design and decision cycle implementation for production forecasting are leveraged from an implicitly coupled scheduler, referred to as "Field management". Surface network integration in the integrated asset model is flexible and dependent on the level of fidelity needed – with complete control of all entities inside the surface network model provided by the "Field management" system. Optimisation capabilities provided with the "Field management" system allows for "automatic updates" to entities in the production system to optimise the recovery. "Model updates" pertinent to production data updates is driven by the "rapid model update" technique. Flexible coupling techniques and niche optimisation capabilities offered by the "Field management" scheduler between the different domain models enable optimising the asset's production with implicit operational constraints. The superior performance offered through state-of-the-art solvers, fit for purpose fidelity and parallel scalability offers a practical advantage to this integrated asset management approach. "Rapid model update" workflow allows for seamless and fast integration of production data updates within the integrated asset model, thereby keeping the model in an "evergreen" state, reflective of the subsurface dynamics and operational changes. This paper provides the most practical solution for Integrated asset modelling implementation that provides flexibility to balance between performance and fidelity by leveraging the latest technological advancements and workflows. It is the first solution that offers an optimisation technique capable of "rapid and automatic model updates" and python extensibility to achieve realistic field planning forecasts.

Full textAbstract:
This paper describes some of the outcomes of the development of finite element modelling guidelines for the stress analysis of bolted joints in pressure vessels and piping. The modelling methods originally developed at Rolls-Royce typically used 2D axisymmetric models as this was deemed adequate at the time. However, computing software and hardware improvements have subsequently been made which enable more realistic 3D bolted joint models to be solved where a greater level of geometric detail is required. For example the bolts, nuts and perforated flanges can now be represented more realistically reducing the degree of geometric abstraction that is required. Also, modern finite element codes such as ABAQUS and ANSYS now offer gasket elements which enable the initial compression, in-service performance and unloading of the joint to be modelled more realistically. Additionally, contact techniques can also be used to simulate the axial and radial distribution of thread load in the joint which will affect the stress distribution remote from the threaded region. Consequently, the modelling guidelines have been updated and provide guidance for stress engineers to decide which degree of model complexity is warranted.

The article discusses the issue of intergenerational tension in the collaboration of differently old colleagues. It is a follow-up to the outputs of the research project �Intergenerational Management in Support of Digitalization in the Building Industry� financed by Technological Agency of the Czech Republic. The author focuses on the problems of intergenerational cooperation and analyze the current situation from the point of view of generations division according to typical generational behavior. The solution is based on a model of intergenerational cooperation based on improving communication between generations and sharing digital competences. When modelling inter-generational collaboration, willingness to cooperate is a key issue. The article focuses on the causes of intergenerational tension, which has its roots in the current social climate and the rejection of authorities. The research project shows the way how to deal with the situation in companies introducing digital data processing and offers a relatively simple solution that aims to improve intergenerational cooperation and digital competence sharing in order to increase the competitiveness of companies. At the same time, it offers the way how to effectively use older employees and offer them job satisfaction.

Full textAbstract:
The overarching goals for the UK in relation to global water security are to; tackle and reverse growing water insecurity and its consequences caused by depletion and degradation of natural water sources; and address poor water management and increasing demand. To do this, the UK has a well-developed water ‘offer’ that together can help reach the goal of global water security. This note details some of that water offer: UK water leadership: The UK developed the concept of modern sanitation and water supply, with an early example being the Victorian Bazalgette London sewer; Ownership and regulation: The UK has four models of ownership: government department in Northern Ireland, GoCo in Scotland, Mutual in Wales, and private companies in England. But the common thread is strong and clear, regulation to deliver the right outcomes for society; Competition and markets: The UK set up the world’s first water retail markets for business customers, delivering savings and environmental benefits. Similar market mechanisms are being developed for sewage sludge, which will help drive circular economy solutions; Innovation: The UK has a huge number of water tech start-ups and most water companies have labs and pilot schemes to support these fledgling companies. At the same time, the English regulator, Ofwat, has established a huge innovation fund, which along with the Scottish Hydro Nation initiative has made the UK the best place in the world for water innovation and tech.

Full textAbstract:
The first-mile, last-mile problem is a significant deterrent for potential transit riders, especially in suburban neighborhoods with low density. Transit agencies have typically sought to solve this problem by adding parking spaces near transit stations and adding stops to connect riders to fixed-route transit. However, these measures are often only short-term solutions. In the last few years, transit agencies have tested whether new mobility services, such as ridehailing, ridesharing, and microtransit, can offer fast, reliable connections to and from transit stations. However, there is limited research that evaluates the potential impacts of these projects. Concurrently, there is growing interest in the future of automated vehicles (AVs) and the potential of AVs to solve this first-mile problem by reducing the cost of providing these new mobility services to promote access to transit. This paper expands upon existing research to model the simulate the travel and revenue impacts of a fleet of automated vehicles that provide transit access services in the San Francisco Bay Area offered over a range of fares. The model simulates a fleet of AVs for first-mile transit access at different price points for three different service models (door-to-door ridehailing and ridesharing and meeting point ridesharing services). These service models include home-based drop-off and pick-up for single passenger service (e.g., Uber and Lyft), home-based drop-off and pick-up for multi-passenger service (e.g., microtransit), and meeting point multi-passenger service (e.g., Via).

Over the last decade, many researchers have conducted randomised trials alongside economic models. The work of these researchers has shown that both approaches are strengthened by their combined use and the conclusions they lead to are full of policy implications. In the latest CEDIL Methods Brief, Edoardo Masset, Research Director, CEDIL Programme, uses three examples to offer tips on the application of modelling to evaluate development interventions and explore various policy questions. The brief shows that models and experiments should be seen as complementary, rather than as alternative approaches. This brief is based on the CEDIL Inception Paper No. 9, Structural Modelling in Policy Making, by Orazio Attanasio and Debbie Blair. This paper is available on the CEDIL website.

Minority language media (MLM) faced significant disruption resulting from the digitalisation processes which brought in increased competition and challenged traditional business models. With a new wave of technological advancements in auto-translation, however, there may be opportunities to grow audience within different speaker groups. This blogpost considers the model of Scottish Gaelic broadcaster BBC Alba, which is sustained by a two-pronged strategy of content for speakers and non-speakers, concluding that other outlets, including newspapers, could utilise auto-translation tools to grow their audience as readership habits evolve. Caution is also expressed towards the possibility of majority-language first practices creeping in out of convenience, serving as a reminder that regulation and public funding must ensure that minority language content is continuously produced, and that the current wave of digitalisation is advantageous for MLM.

United Nations University Institute for Water, Environment and Health, December 2021. http://dx.doi.org/10.53328/uxuo4751.
Full textAbstract:
The report provides a review of how risk is conceived of, modelled, and mapped in studies of infectious water, sanitation, and hygiene (WASH) related diseases. It focuses on spatial epidemiology of cholera, malaria and dengue to offer recommendations for the field of WASH-related disease risk mapping. The report notes a lack of consensus on the definition of disease risk in the literature, which limits the interpretability of the resulting analyses and could affect the quality of the design and direction of public health interventions. In addition, existing risk frameworks that consider disease incidence separately from community vulnerability have conceptual overlap in their components and conflate the probability and severity of disease risk into a single component. The report identifies four methods used to develop risk maps, i) observational, ii) index-based, iii) associative modelling and iv) mechanistic modelling. Observational methods are limited by a lack of historical data sets and their assumption that historical outcomes are representative of current and future risks. The more general index-based methods offer a highly flexible approach based on observed and modelled risks and can be used for partially qualitative or difficult-to-measure indicators, such as socioeconomic vulnerability. For multidimensional risk measures, indices representing different dimensions can be aggregated to form a composite index or be considered jointly without aggregation. The latter approach can distinguish between different types of disease risk such as outbreaks of high frequency/low intensity and low frequency/high intensity. Associative models, including machine learning and artificial intelligence (AI), are commonly used to measure current risk, future risk (short-term for early warning systems) or risk in areas with low data availability, but concerns about bias, privacy, trust, and accountability in algorithms can limit their application. In addition, they typically do not account for gender and demographic variables that allow risk analyses for different vulnerable groups. As an alternative, mechanistic models can be used for similar purposes as well as to create spatial measures of disease transmission efficiency or to model risk outcomes from hypothetical scenarios. Mechanistic models, however, are limited by their inability to capture locally specific transmission dynamics. The report recommends that future WASH-related disease risk mapping research: - Conceptualise risk as a function of the probability and severity of a disease risk event. Probability and severity can be disaggregated into sub-components. For outbreak-prone diseases, probability can be represented by a likelihood component while severity can be disaggregated into transmission and sensitivity sub-components, where sensitivity represents factors affecting health and socioeconomic outcomes of infection. -Employ jointly considered unaggregated indices to map multidimensional risk. Individual indices representing multiple dimensions of risk should be developed using a range of methods to take advantage of their relative strengths. -Develop and apply collaborative approaches with public health officials, development organizations and relevant stakeholders to identify appropriate interventions and priority levels for different types of risk, while ensuring the needs and values of users are met in an ethical and socially responsible manner. -Enhance identification of vulnerable populations by further disaggregating risk estimates and accounting for demographic and behavioural variables and using novel data sources such as big data and citizen science. This review is the first to focus solely on WASH-related disease risk mapping and modelling. The recommendations can be used as a guide for developing spatial epidemiology models in tandem with public health officials and to help detect and develop tailored responses to WASH-related disease outbreaks that meet the needs of vulnerable populations. The report’s main target audience is modellers, public health authorities and partners responsible for co-designing and implementing multi-sectoral health interventions, with a particular emphasis on facilitating the integration of health and WASH services delivery contributing to Sustainable Development Goals (SDG) 3 (good health and well-being) and 6 (clean water and sanitation).

Full textAbstract:
Achieving universal electrification in sub-Saharan Africa requires creative solutions. Renewable mini-grids are a promising technology to electrify remote communities with a substantial productive demand, mainly from agro-processing. Mini-grids have experienced fast growth and there are now around 2,200 systems in the sub-Saharan Africa region. However, their economic case in the sub-continent is unclear. Most mini-grids are struggling not only to obtain a profit but also to recover costs. This Research Report describes the case of a private company in Tanzania implementing a business model for mini-grids that promotes productive uses of energy to achieve financial sustainability (the ‘Keymaker model’). A group of researchers worked jointly with the mini-grid developer to procure equipment for fish processing activities, support local entrepreneurs to use electricity productively, and to document and learn from the process. Although the business model was ultimately unsuccessful – facing high regulatory risks, high initial tariffs required to recover costs, and complex management of agro-processing activities – the project offers useful lessons and considerations for future efforts to promote mini-grids, and how public–private partnerships can help improve affordability and reduce regulatory risks.

Full textAbstract:
Public interest, research and policies about dual language education and the multiple benefits of bilingualism and biliteracy have led to shortages of bilingual education teachers in the state and nation. School districts and educator preparation programs are actively looking for pathways of bilingual teacher preparation to meet local demands for more dual language programs. Modeled after medical residencies, teacher residencies are deeply rooted in clinical training, typically placing residents in classrooms with experienced teachers in high-needs schools where they are supported in their development. Teacher residencies allow for the recruitment of teachers, offer strong clinical preparation, connect new teachers to mentors and provide financial incentives to retain teachers in the school/district of residency. Little is known however, about bilingual teacher residencies in the state. Following a review of various data sources, researchers find that, to date, there are few bilingual teacher residencies offered and that there is a need to expand and study bilingual teacher residencies as one of the most viable pathways to respond to this shortage.
