Alpha-decay energies of superheavy nuclei for the Fayans functional
2016
Alpha-decay energies for several chains of super-heavy nuclei are calculated within the self-consistent mean-field approach by using the Fayans functional FaNDF$^0$. They are compared to the experimental data and predictions of two Skyrme functionals, SLy4 and SkM*, and of the macro-micro method as well. The corresponding lifetimes are calculated with the use of the semi-phenomenological formulas by Parkhomenko and Sobiczewski and by Royer and Zhang.
Multimode OPOs as Sources for Multipartite Entanglement
2009
We present here multimode OPOs as a source of multimode squeezing and multipartite entanglement of continuous-wave light beams, with applications to the engineering of multimode states of light in the spatial and spectral domains.
Harnessing stakeholder input on Twitter: A case study of short breaks in Spanish tourist cities
2019
Abstract Knowledge of how destination marketing organisations (DMOs) use Twitter is still limited. This study aimed to assess how DMOs' Twitter activity affects hotel occupancy in short-break holidays. Key dimensions of Twitter that may affect hotel occupancy in tourist destinations were first identified. A longitudinal study using data for 10 Spanish DMOs was conducted to forecast hotel occupancy. Twitter application programming interfaces were used to gather data on tweets by DMOs and retweets and likes by users. Text mining was used to analyse the tweets by DMOs, differentiating between tweets related to events, attractions, socialisation, and marketing. Data were analysed using artifici…
Diversification and performance in the mobile app market: The role of the platform ecosystem
2019
Abstract We examine the effect of app developers' product line diversification decision on their performance and shed light on whether the type of platform ecosystem (open versus closed) where they commercialize apps influences this effect. We compare the revenue performance of diversified and specialized developers in Apple's App Store and Google Play. We show that in the Apple's App Store (closed platform) diversified developers always display lower performance than their specialized counterparts. In Google Play (open platform) diversification is beneficial in categories where diversified developers have predominant market share, whereas it is detrimental in categories dominated by specia…
Generation Z and Organizational Listening on Social Media
2020
Young people are avid users of social media and have appeared as a powerful force for social change, as shown by the ranks of those who have joined Greta Thunberg in the global climate movement. In addition to challenging political institutions and governments, young people today are also holding the corporate world accountable. To respond to young people’s expectations, brands, and organizations have turned to social media to interact and build relationships with them. However, critics have lamented that these attempts often fail and that young people’s trust in institutions, brands, and organizations continues to decline. This article asks how young people perceive organizational listenin…
Cross-lagged associations between perceived external employability, job insecurity, and exhaustion: Testing gain and loss spirals according to the Co…
2012
Summary This study investigates perceived external employability (PEE) as a personal resource in relation to job insecurity and exhaustion. We advance the idea that PEE may reduce feelings of job insecurity and, through felt job insecurity, also exhaustion. That is, we probe the paths from PEE to job insecurity and from job insecurity to exhaustion. We furthermore account for possible reversed causality, so that exhaustion felt job insecurity and felt job insecurity PEE. This aligns with insights from the Conservation of Resources Theory, which is built on the assumption of resource caravans passageways and associated gain and loss spirals. We based the results on a sample of 1314 workers…
Change Talk in Hospital Management Groups
2020
Recent national healthcare reforms have resulted in many changes to healthcare organizations. When social realities are enacted in social interactions, changes also occur in communication through discourses. In public hospitals, middle management groups form one important platform for change talk. This study aimed to identify and understand how change talk emerges in management group meetings. Data were collected from 10 hospital meetings, and change-related interactions were explored by analyzing sensemaking and positioning. In the data, change talk took three forms: collaboration, control and confrontation. These forms consisted of change discourses (change as a possibility, concealed cha…
Towards a novel conceptual framework for understanding mergers in higher education
2015
ABSTRACTThis paper tries to develop a conceptual framework for a comprehensive understanding of the merger process, which is regarded as a matter of institutionalization of organizational innovation. In the framework, a number of factors affecting merger process or institutionalization of merger are identified, such as those related to environmental issues, economic benefits, institutional compatibility and human agency. The framework hopefully narrows our knowledge gap on theorizing innovation process, in general, and university merger, in particular. It also has a potential to better assist decision-makers and managers in planning and implementing university mergers.
The landscape of strongholds
2016
La difesa dei territori ha offerto risultati straordinari alla formazione e alla trasformazione del territorio e del paesaggio, a volte con tratti spettacolari e dimensioni incredibili. La celebrazione del centenario dell’inizio della Prima guerra mondiale ha offerto lo spunto per una riflessione sulle ricadute indotte sul paesaggio dagli eventi bellici, e più in generale dalla realizzazione di strutture difensive e del loro rapporto con il paesaggio circostante. Territorial defence led to extraordinary results in terms of forming and transforming the territory and landscape, at times with spectacular sights and incredible sizes. The one hundred year anniversary since the beginning of the F…
Preparation and Characterization of Pulp and Paper Mill Sludge-Activated Biochars Using Alkaline Activation : A Box–Behnken Design Approach
2022
This study utilized pulp and paper mill sludge as a carbon source to produce activated biochar adsorbents. The response surface methodology (RSM) application for predicting and optimizing the activated biochar preparation conditions was investigated. Biochars were prepared based on a Box–Behnken design (BBD) approach with three independent factors (i.e., pyrolysis temperature, holding time, and KOH:biomass ratio), and the responses evaluated were specific surface area (SSA), micropore area (Smicro), and mesopore area (Smeso). According to the RSM and BBD analysis, a pyrolysis temperature of 800 °C for 3 h of holding and an impregnation ratio of 1:1 (biomass:KOH) are the optimum conditions f…
