Hormone replacement therapy improves contractile function and myonuclear organization of single muscle fibres from postmenopausal monozygotic female …
2013
Ageing is associated with a decline in muscle mass and strength leading to increased physical dependency in old age. Postmenopausal women experience a greater decline than men of similar age in parallel with the decrease in female sex steroid hormone production. We recruited six monozygous female twin pairs (55-59 years old) where only one twin pair was on hormone replacement therapy (HRT use = 7.8 ± 4.3 years) to investigate the association of HRT with the cytoplasmic volume supported by individual myonuclei (myonuclear domain (MND) size,) together with specific force at the single fibre level. HRT use was associated with a significantly smaller (∼27%; P < 0.05) mean MND size in muscle fib…
Language teacher identities as socio-politically situated construction: Finnish and Brazilian student teachers’ visualisations of their professional …
2021
Abstract The process of envisioning the future is central to teachers’ identity construction, but different environments create distinct sociocultural conditions for the process. This qualitative study drawing on visual-textual methods compares Finnish and Brazilian student teachers’ desired and feared professional futures. Two different perspectives on future identities were detected: a desire for status and a desire for meaningfulness. The results revealed the radically different social status of teaching in the two countries and the role this played in the envisioned identities. The study highlights the importance of awareness of the socio-political nature of identity construction in dev…
A Smart Contract Based Recommender System
2019
Nowadays information available on the World Wide Web has reached unprecedented growth and it makes difficult for users to find the most relevant for them. In order to alleviate such issue, Recommender Systems (RSs) have been proposed to collect opinions and preferences about a set of items, process such preferences and build a personalized information access. While the most part of current RSs exploit centralized architecture to provide the service, in this manuscript we propose an alternative approach for building a general purpose RSs that provides to users with more transparent and decentralized rating strategy. Indeed, the proposed framework is built on top of a Distributed Ledger techn…
I contratti di rete: valutazioni oltre l'emergenza
2018
The network contract: some evaluations after the emergency. The debate over the Italian network contract develops in the phase of the heaviest crisis for Italians firms. This article evaluates limits and opportunities of network contracts. Findings are based on 14 network cases selected among declining or growing productive sectors in the context of two regions of the South: Apulia and Sicily. Formal networks, although initiated later than in the Northern regions, are indeed now widespread also in the South. The main findings concern the inability of formal networks to support actors to come out of the crisis. Actually, the decline of the sector is one of the most relevant factors that can …
L'efficacité des privatisations françaises : une vision dynamique à travers la théorie de la gouvernance
2004
International audience; A reading of the process of privatization through the corporate governance theory leads to propose a model taking into account, on the one hand, the time dimension of the process of privatization, on the other hand, the contextual, organizational, governance and strategic variables which influence this process. After replicating some traditional tests, we test this model on a sample of French privatized firms and on a seven years horizon. The positive effect traditionally attributed to privatizations is not confirmed. The importance of the effect is subordinated to some of the suggested variables.; Une lecture du processus de privatisation à travers la théorie de la …
Multivariate modeling and analysis of regional ocean freight rates
2018
Abstract In this paper, we propose a new multivariate model for the dynamics of regional ocean freight rates. We show that a cointegrated system of regional spot freight rates can be decomposed into a common non-stationary market factor and stationary regional deviations. The resulting integrated CAR process is new to the literature. By interpreting the common market factor as the global arithmetic average of the regional rates, both the market factor and the regional deviations are observable which simplifies the calibration of the model. Moreover, forward contracts on the market factor can be traded in the Forward Freight Agreement (FFA) market. We calibrate the model to historical spot r…
Automorphisms of 2–dimensional right-angled Artin groups
2007
We study the outer automorphism group of a right-angled Artin group AA in the case where the defining graph A is connected and triangle-free. We give an algebraic description of Out.AA/ in terms of maximal join subgraphs in A and prove that the Tits’ alternative holds for Out.AA/. We construct an analogue of outer space for Out.AA/ and prove that it is finite dimensional, contractible, and has a proper action of Out.AA/. We show that Out.AA/ has finite virtual cohomological dimension, give upper and lower bounds on this dimension and construct a spine for outer space realizing the most general upper bound. 20F36; 20F65, 20F28
Hilbert space operators with two-isometric dilations
2021
A bounded linear Hilbert space operator $S$ is said to be a $2$-isometry if the operator $S$ and its adjoint $S^*$ satisfy the relation $S^{*2}S^{2} - 2 S^{*}S + I = 0$. In this paper, we study Hilbert space operators having liftings or dilations to $2$-isometries. The adjoint of an operator which admits such liftings is characterized as the restriction of a backward shift on a Hilbert space of vector-valued analytic functions. These results are applied to concave operators (i.e., operators $S$ such that $S^{*2}S^{2} - 2 S^{*}S + I \le 0$) and to operators similar to contractions or isometries. Two types of liftings to $2$-isometries, as well as the extensions induced by them, are construct…
El killer adquisition theory of harm y la autonomía de las partes: illumina/pacific biosciences y paypal/izettle
2022
: Partiendo del trabajo expuesto por Cunningham, Ederer y Ma titulado: “Killer Acquisition” publicado en el “Journal of Political Economy” en marzo 2021, se analizará la fusión de Illumnia, Inc/Pacific Biosciences of California, Inc (dos empresas del sector biotecnológico) y la de Paypal Holdings/iZettle con el fin de dar respuesta a las siguientes interrogantes: ¿La US Federal Trade Commission contaba con suficiente evidencia jurídica y económica para limitar la autonomía de las partes Illumnia, Inc/Pacific Biosciences of California, en pro de la innovación y competencia o se trató de una coartación a la libertad contractual cuyo único objetivo era la maximización de los rendimientos econó…
