Psychological Well-Being and Career Indecision in Emerging Adulthood: The Moderating Role of Hardiness
2016
Choosing a career path is an important developmental task during the transition from adolescence to adulthood. However, many emerging adults (EAs)-individuals between 18 and 29 years of age (Inguglia et al., 2016)-struggle to get their career decision-making processes under way because they need a long time to explore various possible career directions (Arnett, 2004; Miller & Rottinghaus, 2014). In particular, this condition concerns EAs who are never employed and is traditionally associated with the construct of career indecision (Gati et al., 2011; Gati, Krausz, & Osipow, 1996), referring to the difficulties that can slow or even stop the career decision-making process.Among such difficul…
Organizational Persistence in Highly Institutionalized Environments: Unpacking the Relation Between Identity and Resilience
2021
AbstractDespite growing academic interest in understanding the conditions under which resilient organizations adapt to challenging circumstances, little attention to date has been paid to the role played by ‘soft’ factors such as identity as an enabler or property of resilient behaviour. In this chapter, we propose that different forms of legitimacy contribute to the framing of acceptable identities affecting the endurance of central elements over time, thus shaping resilience. By splitting up forms of legitimacy and by analysing elements of organizational identity separately, we provide a novel framework that enables a deeper understanding of identity formation processes in complex environ…
Carbon–Phosphorus Coupling from C^N Cyclometalated Au III Complexes
2020
Abstract With the aim of exploiting new organometallic species for cross‐coupling reactions, we report here on the AuIII‐mediated Caryl−P bond formation occurring upon reaction of C^N cyclometalated AuIII complexes with phosphines. The [Au(C^N)Cl2] complex 1 featuring the bidentate 2‐benzoylpyridine (CCON) scaffold was found to react with PTA (1,3,5‐triaza‐7‐phosphaadamantane) under mild conditions, including in water, to afford the corresponding phosphonium 5 through C−P reductive elimination. A mechanism is proposed for the title reaction based on in situ 31P{1H} NMR and HR‐ESI‐MS analyses combined with DFT calculations. The C−P coupling has been generalized to other C^N cyclometalated Au…
Temporomandibular arthropathies : a retrospective study with histopathological characteristics
2018
Background To investigate the incidence of temporomandibular arthropathies diagnosed in a university center and to describe their histopathological characteristics. Material and Methods Temporomandibular arthropathy cases with corresponding slides were selected from an oral and maxillofacial surgical pathology service. Cases of exclusively articular disc disease were not included. Results The mean age was 31.3 years with a predominance of females (69.7%). Of these diagnoses, 53.6% were unilateral condylar hyperplasia, 17.8% were bony ankylosis, 14.3% were degenerative joint disease, 10.7% were osteochondroma, and 3.6% were synovial chondromatosis. Condylar hyperplasia presented as thick fib…
Strong stabilization of amorphous calcium carbonate emulsion by ovalbumin: gaining insight into the mechanism of 'polymer-induced liquid precursor' p…
2011
8 pages; International audience; The impact of the ovo proteins ovalbumin and lysozyme-present in the first stage of egg shell formation-on the homogeneous formation of the liquid amorphous calcium carbonate (LACC) precursor, was studied by a combination of complementing methods: in situ WAXS, SANS, XANES, TEM, and immunogold labeling. Lysozyme (pI = 9.3) destabilizes the LACC emulsion whereas the glycoprotein ovalbumin (pI = 4.7) extends the lifespan of the emulsified state remarkably. In the light of the presented data: (a) Ovalbumin is shown to behave commensurable to the 'polymer-induced liquid precursor' (PILP) process proposed by Gower et al. Ovalbumin can be assumed to take a key rol…
Effect of Composition on the Photoelectrochemical Behavior of Anodic Oxides on Binary Aluminum Alloys
2006
The photoelectrochemical behavior of anodic films on Al alloys, containing titanium, tantalum, and tungsten (valve metals), has been studied as a function of alloy composition and anodizing conditions. Photocurrent spectroscopy has been used to get information on bandgap and the flatband potential values of different mixed oxides. Both insulator-like and semiconducting behavior has been observed for anodic oxides grown on Al-W and Al-Ti alloys dependent on alloy initial composition. Optical bandgap values, E opt g , of different oxides are in accordance with predictions based on the correlation between E opt g and the difference of electronegativities of the oxide constituents, indicating p…
Percepción del alumnado sobre evaluación formativa y compartida: conectando dos universidades a través de la Blogosfera
2017
The aim of this study was to evaluate differences in physical education students’ perception on an educational innovation based on formative and peer assessment through the blogosphere. The sample was made up of 253 students from two Spanish universities. Data was collected using a self-reported questionnaire and t tests were employed in order to find differences among students’ groups. Results show significant differences in almost all of the items on which the students were questioned. Basque students were more satisfied with the assessment tool used than the Valencian students. Students found the blogosphere more active, meaningful, functional and motivating and that it made for collabor…
Fiber Bragg gratings with various chirp profiles made in etched tapers
1996
We have studied, both theoretically and experimentally, fibre Bragg gratings with a number of different chirp profiles. These chirp profiles can be easily achieved with a recently demonstrated technique involving a taper of desired profile being etched into the cladding of a fibre. Performances of gratings with linear, quadratic, periodically modulated and step chirp profiles are numerically analysed. The versatility of the technique is demonstrated when linearly and quadratically chirped gratings were made as examples of continuous chirp and gratings with step chirps were made as examples of discontinuously chirped structure.
Condensation of classical optical waves beyond the cubic nonlinear Schrodinger equation
2012
International audience; A completely classical nonlinear wave is known to exhibit a process of condensation whose thermodynamic properties are analogous to those of the genuine Bose-Einstein condensation. So far this phenomenon of wave condensation has been studied essentially in the framework of the nonlinear Schrodinger (NLS) equation with a pure cubic Kerr nonlinearity. We study wave condensation by considering two representative generalizations of the NLS equation that are relevant to the context of nonlinear optics, the nonlocal nonlinearity and the saturable nonlinearity. For both cases we derive analytical expressions of the condensate fraction in the weakly and the strongly nonlinea…
Bradoriid Arthropods from the Lower-Middle Cambrian of Scania, Sweden
2008
Three species of bradoriid arthropods from the lower to middle Cambrian transitional interval of Scania, southern Sweden, are described and illustrated: Beyrichona tinea from the top of the traditional lower Cambrian (Gislov Formation; Ornamentaspis? linnarssoni Zone), and Hipponicharion eos and Alutella sp. from the basal portion of the traditional middle Cambrian (lowermost part of the Alum Shale Formation). The bradoriid fauna compares most closely with others previously described from western and eastern Avalonia (New Brunswick and England). The record of B. tinea suggests a correlation between the “Protolenus Zone” (Hupeolenus Zone) of western Avalonia and the O.? linnarssoni Zone of S…
