Diritto e volontà di disconnessione, due elementi che devono viaggiare in parallelo
No full textGli autori di questo contributo – do-centi in diversi atenei del mondo e membri dell’International Network on Technology, Work and Family (INTWAF) della Università del Quebec a Montreal – si interrogano se i contri-buti della ricerca scientifica, le espe-rienze delle organizzazioni di lavoro e le policy delle istituzioni governative possano dialogare per fornire soluzio-ni a quello che si annuncia come uno dei fenomeni più rilevanti nella vita moderna: la necessità di moderare i nostri comportamenti di connettività
Il nuovo impiego non è soddisfacente: meglio resistere o limitare i danni?
No full textNon è affatto ciò che mi aspettavo... IL PRIMO GIORNO DI MIA RICCI era iniziato male. Mia era entusiasta del suo nuovo ruolo di responsabile di programma presso Rescue, la più antica e grande organizzazione umanitaria impegnata nella lotta alla povertà globale. Si era alzata presto, aveva portato a spasso i cani, aveva fatto colazione con il suo ragazzo, Mateo, aveva preparato il pranzo ed era comunque riuscita ad arrivare in ufficio prima delle 9. Aveva pensato che arrivando in anticipo avrebbe fatto una buona impressione. All’ingresso, Mia riconobbe alcuni volti familiari già incontrati durante il colloquio di selezione, ma l’addetto alla reception fu l’unico a salutarla
A network approach to work-family conflict
No full textMost human behaviours, including those instrumental for reducing Work–Family Conflict (WFC), take place in the context of social relationships. However, the role of social networks in an individual's WFC goal pursuit process has not received sufficient attention, as most current research is dominated by an agentic perspective that argues that individuals possess the capabilities to change the demands and resources associated with their roles freely. We believe that the reality faced by many workers is more composite, as the various work and family stakeholders present in an individual's network can create significant constraints and opportunities that are capable of inhibiting or enhancing their agency. In this paper, we aim to examine how the ecosystem of network relationships in an individual’ social network can influence his or her overall capability to minimise WFC. Building on insights from dynamic network theory, a recently introduced framework in the social network literature, we propose a conceptual model that explains the specific roles that work and family stakeholders (i.e., supporters, preventers, resistors, reactors, negators, interactants, or observers) can assume with respect to goal strivers' attempts to manage WFC. Building on prior work-family and social network research, we illustrate how two characteristics of the network in which an individual is embedded (i.e., centrality and density) can shape the magnitude of social network influence on WFC. Implications for theory and practice are also discussed
Relationship between perceived justice and identification: The mediating role of organizational images
No full textPurpose – The purpose of this paper is to contribute to our understanding of the antecedents of organizational identification. Specifically, this paper aims to integrate two perspectives developed within the social identity domain, labeled “cognitive” and “relational,” by comparing and reconciling their relationship organizational identification.
Design/methodology/approach – This study uses a survey method and a structured questionnaire to collect data from people working in a call center. The hypotheses were tested on a sample of 743 employees by using structural equation models and Hayes’ (2017) bootstrapping procedure.
Findings – The results provide evidence for a mediational model in which the attractiveness of organizational images (cognitive representations) mediates the relationship between perceived justice (relational judgments) and organizational identification.
Research limitations/implications – The data were obtained from a single source in a cross-sectional design, which may inflate common method variance. To address threats to validity, the authors employed several procedures, the results of which revealed that no parameters corresponding to the hypotheses changed in sign or significance, thus suggesting that the presence of method bias, if any, was nonconsequential.
Practical implications – Not only does perceived justice relate to the sense of belonging to an organization, but it also contributes to shaping the long-term cognitive representations of the company. In particular, both HR and line managers should be aware that in this respect, the interactional dimension of justice shows the strongest effect.
Originality/value – Building on and enlarging the scope of the extant literature, the findings contribute to our knowledge of how relational judgments shape cognitive images about the company, influencing, in turn, the individual–organization relationship
Who are the Others? A Stakeholder Approach to Organizational Image and its Congruence with Identity
No full textOrganizational image can be defined as the manner in which the members of an organization believe that other people view the organization. We propose a stakeholder approach to the study of organizational image and clarify who are the others that the definition makes reference. In addition, we examine the relationship among the organizational images (construed by managers around a set of key stakeholders), organizational identity, goal congruence, and company identification using a sample of 192 CEOs of Italian firms. We hypothesized that goal congruence mediates the relationship of identity and images with identification. Our results extend previous research by providing a fine-grained approach to the study of organizational images and clarifying how congruent identity and images foster organizational identification
Global regularity for a logarithmically supercritical hyperdissipative dyadic equation
No full textWe prove global existence of smooth solutions for a slightly supercritical dyadic model. We consider a generalized version of the dyadic model introduced by Katz-Pavlovic 10 and add a viscosity term with critical exponent and a supercritical correction. This model catches for the dyadic a conjecture that for Navier-Stokes equations was formulated by Tao 13
La concezione architettonica
No full textQuesto capitolo presenta l’idea architettonica alla base della Casa dei Risvegli Luca De Nigris e le conseguenti soluzioni strutturali relative agli spazi interni ed esterni che ne sono derivate. Si tratta di aspetti rilevanti per la Casa dei Risvegli in quanto la struttura in cui si inserisce il progetto determina inevitabilmente i flussi organizzativi (p.e., la comunicazione interna, il coordinamento tra gli operatori, ...) e parallelamente la qualità della vita all’interno della struttura (p.e., i rapporti tra operatori e famiglie, il contatto tra le famiglie stesse, ...)
Smooth solutions for the dyadic model
No full textWe consider the dyadic model, which is a toy model to test issues of well-posedness and blow-up for the Navier-Stokes and Euler equations. We prove well-posedness of positive solutions of the viscous problem in the relevant scaling range which corresponds to Navier-Stokes. Likewise we prove well-posedness for the inviscid problem (in a suitable regularity class) when the parameter corresponds to the strongest transport effect of the nonlinearity

Methodological aspects in synthesis of combined sugar and ethanol production plant
No full textThe synthesis problem, i.e. the definition of type, number and design parameters of system components
and their interconnections, is one of the main research field of chemical and energy engineering. The
present paper aims at clarifying some methodological aspects for the systematic synthesis of processes
by suggesting an organized procedure which is applied here to a case study of a sugarcane mill. The
procedure starts from the definition of a Basic Plant Configuration (BPC) that is built according to the
original “concept” of the conversion process (e.g., “transform sugarcane into sugar” or “transform
sugarcane into sugar and ethanol”). The BPC comprises the “basic components”, i.e. those required to
perform the main material and energy conversions, and considers the hot and cold thermal flows only
instead of the heat exchangers. A design optimization of this configuration is then to be performed, in
which the extreme temperature of the thermal streams are considered among the set of the decision
variables. The original BPC is then progressively changed into new BPCs by means of structural modifications
including component staging and addition of new material connections or subprocesses.
Modifications to the original BPC are mainly derived from the interpretation of the process Grand
Composite Curve (GCC), a graphical tool provided by Pinch Analysis, which helps identify the potential
for process internal heat recovery. Although the development of an automated algorithm is the final goal
of the research activities, this article aims at showing that the proposed approach can be used to
systematically explore the most significant process synthesis options. In the light of the suggested
procedure we investigate here three different process concepts for the conversion of sugarcane. Starting
from the original concept of sugar production, process structural developments towards the combined
sugar and ethanol production are proposed and discussed
