Different facets of attitudes towards having children: The Procreation Attitude Scale (PrAttS)

2020

The attitudes towards children are more complex than simple positive/negative distinctions. In the present study, we sought in two studies (N = 445) to provide a tool to explore different facets of attitudes towards babies and procreation by developing and validating a questionnaire regarding attitudes towards procreation. Study 1 was conducted to develop an English language scale tapping into adults’ attitudes toward having offspring. A larger number of statements were formulated that expressed an emotional value and motivational attitudes towards having babies. The sample consisted of n = 157 participants. Participants’ responses were subjected to a preliminary principal components analys…

Unidirectional Magnon-Driven Domain Wall Motion Due to the Interfacial Dzyaloshinskii-Moriya Interaction

2018

We demonstrate a unidirectional motion of a quasiparticle without an explicit symmetry breaking along the space-time coordinate of the particle motion. This counterintuitive behavior originates from a combined action of two intrinsic asymmetries in the other two directions. We realize this idea with the magnon-driven motion of a magnetic domain wall in thin films with interfacial asymmetry. Contrary to previous studies, the domain wall moves along the same direction regardless of the magnon-flow direction. Our general symmetry analysis and numerical simulation reveal that the odd order contributions from the interfacial asymmetry is unidirectional, which is dominant over bidirectional contr…

Dynamical left-right symmetry breaking.

1995

We study a left--right symmetric model which contains only elementary gauge boson and fermion fields and no scalars. The phenomenologically required symmetry breaking emerges dynamically leading to a composite Higgs sector with a renormalizable effective Lagrangian. We discuss the pattern of symmetry breaking and phenomenological consequences of this scenario. It is shown that a viable top quark mass can be achieved for the ratio of the VEVs of the bi--doublet $\tan\beta\equiv\kappa/\kappa'$ =~ 1.3--4. For a theoretically plausible choice of the parameters the right--handed scale can be as low as $\sim 20 TeV$; in this case one expects several intermediate and low--scale scalars in addition…

Dissociation between priming and recognition in the expression of sequential knowledge

2002

Exposure to a repeating sequence of target stimuli in a speeded localization task can support both priming of sequence-consistent responses and recognition of sequence components. Here, a task is introduced in which measures of priming and recognition are obtained concurrently, and it is demonstrated that priming of sequence-consistent responses occurs even when test stimuli are not recognized. The results show that sequence knowledge can be expressed in the absence of conscious recognition. However, we also show that this result is consistent with a simple model in which priming and recognition depend on exactly the same underlying memory strength variable.

Agility and system documentation in large-scale enterprise system projects: a knowledge management perspective

2021

Abstract The growth of the agile approach usage comes with a deemphasis on formal documentation (explicit knowledge) and an increased reliance on personal interactions (tacit knowledge) for knowledge transfer. However, the sharing of tacit knowledge poses challenges. The agile approach is prone to knowledge hoarding, as well as knowledge loss from employee turnover and reassignment during periods of significant organizational changes. This study proposes a model that frames documentation and personal interactions as co-agents of system knowledge transfer. We report the preliminary confirmation of crucial antecedents along the dimensions of codification and personalization strategies to supp…

The Urban-Rural Continuum. The Bioclimatic Approach to Design, Between Past and Future

2021

L’ambiente costruito rurale, insieme multiscalare di trasformazioni praticate dall’uomo per accogliere le attività collegate all’agricoltura, suggerisce varie riflessioni sull’approccio bioclimatico nel progetto di architettura. Il contributo mette subito in evidenza il tema del continuum urbano-rurale (luogo intermedio e contraddittorio che condensa le trasformazioni che stanno avvenendo nella contemporaneità, offrendo un banco di prova necessario per tutti i campi del sapere e per tutte le discipline tecnologiche) per evidenziare che la contrapposizione tra urbano e rurale non solo è superata nei fatti, ma anche è teoricamente inadeguata a identificare l’ambiente costruito rurale, nonosta…

Symmetries and Symmetry Groups in Quantum Physics

2013

When one talks about discrete or continuous groups which are to describe symmetries of quantum systems, one must first identify the objects on which the elements of these groups are acting.

ASYMPTOTIC ANALYSIS OF THE LINEARIZED NAVIER–STOKES EQUATION ON AN EXTERIOR CIRCULAR DOMAIN: EXPLICIT SOLUTION AND THE ZERO VISCOSITY LIMIT

2001

In this paper we study and derive explicit formulas for the linearized Navier-Stokes equations on an exterior circular domain in space dimension two. Through an explicit construction, the solution is decomposed into an inviscid solution, a boundary layer solution and a corrector. Bounds on these solutions are given, in the appropriate Sobolev spaces, in terms of the norms of the initial and boundary data. The correction term is shown to be of the same order of magnitude as the square root of the viscosity. Copyright © 2001 by Marcel Dekker, Inc.

The advantage of errorless learning for the acquisition of new concepts' labels in alcoholics

2009

BackgroundPrevious findings revealed that the acquisition of new semantic concepts' labels was impaired in uncomplicated alcoholic patients. The use of errorless learning may therefore allow them to improve learning performance. However, the flexibility of the new knowledge and the memory processes involved in errorless learning remain unclear.MethodNew concepts' labels acquisition was examined in 15 alcoholic patients and 15 control participants in an errorless learning condition compared with 19 alcoholic patients and 19 control subjects in a trial-and-error learning condition. The flexibility of the new information was evaluated using different photographs from those used in the learning…
