Association of Gestational Weight Gain With Adverse Maternal and Infant Outcomes
2019
Importance: Both low and high gestational weight gain have been associated with adverse maternal and infant outcomes, but optimal gestational weight gain remains uncertain and not well defined for all prepregnancy weight ranges. Objectives: To examine the association of ranges of gestational weight gain with risk of adverse maternal and infant outcomes and estimate optimal gestational weight gain ranges across prepregnancy body mass index categories. Design, setting, and participants: Individual participant-level meta-analysis using data from 196 670 participants within 25 cohort studies from Europe and North America (main study sample). Optimal gestational weight gain ranges were estimated…

Structural Dynamics and Intentional Governance in Strategic Interfirm Network Evolution
2015
This paper aims to shed light on the drivers underlying the role and scope of intentional governance of the structural dynamics of whole interfirm networks. Prior research has distinguished networks that are emergent from networks that are orchestrated. While empirical studies have shown situations in which the role and scope of intentional governance of whole interfirm networks has changed in time, and there is a growing interest regards the endogenous drivers of network dynamics, the dimensions that influence intentional governance of network structure dynamics and the way this is carried out remain still to be elucidated. In order to pinpoint these drivers, we leverage the models of netw…
Sostenibilità nelle global supply chains: uno schema di analisi della letteratura
2022
Il presente lavoro si pone l’obiettivo di ricercare quali siano i differenti livelli di governance impegnati nell’implementazione di pratiche di sostenibilità aziendale e come questi siano influenzati e, allo stesso tempo, influenzino distinti contesti istituzionali. A tal fine, viene offerta una revisione della letteratura interpretando la ricerca con due chiavi di lettura, attinenti rispettivamente agli studi di International Corporate Governance e Institutional Theory. Vengono utilizzate due chiavi di lettura distinte per analizzare come, le multinazionali, coinvolte in strutture di governance multilivello e, operanti in contesti istituzionali caratterizzati da sistemi di capitalismo dif…

Il governo dei sistemi reticolari di imprese
2010
Negli ultimi anni un numero crescente di studiosi ha focalizzato l'attenzione sulle opportunità strategiche di creazione e di sfruttamento della conoscenza che si dischiudono alle imprese che operano in un contesto reticolare. Il lavoro muove dalla considerazione che il potenziale economico-cognitivo localizzato in un network di imprese è connesso con tematiche rilevanti quali: le modalità che caratterizzano i processi di produzione e di condivisione della conoscenza che vi risiede; la struttura delle relazioni che interconnettono le imprese interagenti e i loro percorsi evolutivi; e ancor più il nesso che lega dinamicamente gli aspetti processuali-cognitivi con gli aspetti strutturali e di…
El Gran rescate de la prensa española: los anticipos reintegrables durante la Primera Guerra Mundial
2021
Resumen La crisis económica que se derivó de la Primera Guerra Mundial provocó, entre otros efectos, la caída aguda de los resultados económicos de la prensa española y una amenaza real de colapso generalizado. Reconvertida a grandes empresas, con exponentes como el primer trust periodístico español, creado en 1906, los editores de periódicos plantearon por primera vez un dilema clave para el sistema representativo: si se quería que existiese prensa, el tesoro público debía colaborar mediante subvenciones a la compra de papel. Se puso en marcha, de esta forma, el primer gran rescate de la prensa española, con una aportación millonaria de dinero público a empresas privadas que, en teoría, te…
Hot Impression Die Forging Process: An Approach to Flash Design for Tool Life Improvement
2005
In impression die forging the role of the flash geometry is fundamental since a proper design of the flash land strongly influences both the complete die filling and the die wear (i.e. the die life and the related costs). In this paper an integrated approach between numerical simulations and statistical tools was developed with the aim to optimize flash thickness in order to reduce die wear and to minimize material wasting. As wear is regarded, an analytical model depending on sliding velocity, temperature, die hardness and contact pressure was utilized during the numerical simulations of the process in order to reach a wear evaluation for different values of the flash design variables. Thu…
Study of Water Distribution, Textural and Colour Properties of Cold Formulated and Air-Dried Apple Snacks
2022
Vacuum impregnation is considered a cold formulation technology since it allows the incorporation of a desired functional compound into porous plant tissue without applying any heat. It is widely used in combination with the drying process to obtain added-value snacks. The aim of this work was to evaluate the effect of two trehalose concentrations (5 and 10% w/w) on: (i) the water state and texture evolution during the air drying (50 °C, 8 h) of apple snacks vacuum impregnated with blueberry juice, and on (ii) the colour of the final dried apple snacks. The results of nuclear magnetic resonance (NMR) showed that trehalose affects the water mobility of the samples during drying especially af…
Europeans' willingness to pay for ending homelessness: A contingent valuation study.
2020
The purpose of this study is to assess the utility value European citizens put on an innovative social program aimed at reducing homelessness. The Housing First (HF) model involves access to regular, scattered, independent and integrated housing in the community with the support of a multidisciplinary team. Currently, HF is not implemented by most European countries or funded by healthcare or social plans, but randomised controlled trials have stressed significant results for improved housing stability, recovery and healthcare services use. The broader implementation of HF across Europe would benefit from a better understanding of citizens' preferences and "willingness to pay" (WTP) for med…
